After a confrontation in 1926 March 16 ,17 days in Beijing ,the KMT Kuomintang executive committee meeting ,to represent the identity of the same Li Dazhao leadership of the Communist Party of China north area appoint decided to organize the various schools and mass organizations in the assembly .
March 18th morning 10 when ,Net transfer of two girls in the street was called have been,KMT ,the headquarters ,Northern District ,Beijing municipal Party committee ,the Beijing Federation of trade unions ,student federations and other groups in more than 80 schools in total about 5000 people held in Tiananmen against the ultimatum to the National Assembly ,the north side of the square makeshift rostrum hangs the portrait of Mr.
and he wrote the poetic couplet the revolution is not yet completed ,comrades still have to work hard .In front of the banner read Beijing from all walks of life firmly against the ultimatum demonstration meeting .
The eight resolutions Committee of North district leader ,Zhao Shiyan ,attended the meeting ,the president of the general assembly ,the university president Xu Qian delivered a speech speak in excitement emotion ,General Assembly resolution: electricity national unity against the ultimatum ,expelled the minister ,abolishing all unequal treaties, withdrawal of foreign warships ,cable militia to fight against imperialist aggression .
The final assembly has passed eight resolutions .The tragedy occurred after the end of the procession ,led by Li Dazhao ,according to a predetermined route ,set off from Tiananmen ,the East Chang ,Dongdan pailou ,,,finally entered the iron lion Lane (now ) in the East ,the Duan Qirui Administration (now ) square in front of the petition .
The demonstrators representative to guard long representations ,and ask to open the door is placed team in, and invites Duan Qirui and Prime Minister meet .Duan Qirui government staff worried about the situation is out of control, command the volt police to force to break up the parade ,resulting in the death of 47 people, injured more than 200 people .
The well known Beijing female normal university student Liu Hezhen ,Li Dazhao and Chen Qiaonian also injured .Later police in cleaning up the site ,moncler outlet,it will make the property off ,even the clothes were all stripped .
The police were beating the students in March 18th on the same day, Duan Qirui and the Beijing state electricity that this massacre is Xu Qian due to agitation ,wanted Xu Qian ,Li Dazhao ,,,the Gu Mengyu five .
Zhu Jiahua ,Lu Xun ,and dozens of people are on the black list .Li Dazhao ,Xu Qian ,Lu Xun and others were forced to move ,KMT leadership is moved into the embassy .In March 19th public opinion have condemned the killings around the doorway .
In March 20th, Jia the cabinet to resign ,Duan Qirui also ordered the pension .In March 20th the Central Committee of Communist Party of China ,published as Duan Qirui to kill the people to the nation books , national businessmen ,students ,called on the workers ,peasants, soldiers ,emergency united, a non-partisan ,louboutin,consistent struggle, launching a movement more than may great sport ,with snow Bourne Ultimatum .
March 23rd, Beijing people from all walks of life ,various social groups ,each school gathered in large playground for the undead ,held three ?One eight Martyrs Memorial meeting .Lu Xun wrote elegiac couplet : dead or alive again ,how to do .
After this massacre continuous wrote seven official accusation .By Liu Bannong lyricist ,composer lamentations sing beijing .Strong public pressure forced the government to convene a meeting of short Rui ,primarily through slaughter should be at national treatment to the tragedy of the resolution ;investigation and officially recognized : the purpose of gathering petition is legitimate ,and all positive infringement behavior ,and Guard troops suddenly line shot casualties people, real there are 311st major criminal suspects .
In 1926 April, Duan Qirui held the downfall of the government .Zhang Zuolin after Beijing sent into North ,female normal university related ,the University banned books and newspapers, much progress ,searching for progressives .
Early in the morning of April 26th was executed in secret ,Beijing University professor Zhu Jiahua ,acting president Jiang Menglin into the hotel and secret from beijing .The police seized news Museum and a number of progressive press ,arrested members of the Communist party .
Impact of student Liu Hezhen wrecked body times called the incident a brutal massacre .Lu Xun referred to this day as one of the darkest days since the Republic of china .
Chinese intellectuals and the media show a hitherto unknown social conscience ,,,Zhu Ziqing ,Jiang Menglin ,Wang Shijie ,Liang Qichao ,Xu ,Shilian ,Gao Yihan ,Ling Shuhua ,have accused the Duan Qirui administration of .
Si , national newspaper ,Spring division _ Baidu Encyclopedia, world news , Tsinghua , Morning News weekly , to condemn violence .Shao Piaoping presided over the news ,large space continuously published news and commentary ,extensive and in-depth reports on the truth ,louboutin pas cher, news supplement also published articles .
Duan Qirui knelt at the altar on lifelong vegetarian three ?One eight massacre, the whole nation was shocked .Chinese intelligentsia, regardless of their political views and how different academic point of view ,are denounced government and ruling Duan Qirui behavior as retroaction , violence , government Ziqi in people .
the Republic of China ,is the history of dark page ,scholars such as Jiang Menglin ,Zhou Zuoren ,,Lin Yutang ,Zhu Ziqing ,Wen Yiduo ,Wang Shijie ,Xu Shilian ,Gao Yihan ,Yang Zhensheng ,Ling Shuhua ,Shao Piaoping ,Tao Meng and etc.
,have the character appear in newspapers ;Liang Qichao just finishes moving operation ,bedridden ,still did not forget to condemn both in speech and in writing ;Liu Bannong and Zhao Yuanren once again songwriters bige ,groaning sad ,sung while Lu Xun is ; ,article, particularly human .
.. ... Public opinion is not illegal .To this end, said : the intellectuals in the age of even and the most outstanding intellectuals also compared favorably ,in whom we see the most valuable qualities of intellectuals ,they are ,our hearts will never fall of the Great Wall, is real man .
Duan Qirui and his government of the Northern Warlords be kill in cold blood .But the day of Duan Qirui actually does not know its guards fired on students ,not even ordered to student shot , three ?One eight after the tragedy ,Duan Qirui immediately rushed to the scene in front of the deceased ,knelt at the altar ,and then a lifelong vegetarian ,death has not changed is true .
Because of this massacre ,1926 April Duan Qirui Feng Yuxiang was ousted ,back when that Buddhism ,with great concentration ,since the way the householder .According to the three ?One eight massacre in the description of data compilation ,in that the guard shot and killed the student ,Duan Qirui feet : I sigh of Qingming ,be destroyed on one day ! When Congress immediately passed the killing of students primarily for national disposition should be resolution ,Bang Bang chicken _ Baidu Encyclopedia,and the State Council general resignation and Duan Qirui issued on the pension to the bereaved family .
The various schools held various memorial activities, as well as the city memorial meeting and various newspapers and the extensive and detailed report ,the Duan Qirui administration did not dare to be stopped .
Although Duan Qirui generals origin, was a warlord ,is a culture of the warlord .The personality image well ,is the famous six is not prime minister ,i.e. do not smoke ,do not drink ,do not visit ,not gambling ,not greedy ,not accounted for .
This and his family have a great relationship ,Duan Qirui the Huai army generals, when Duan Qirui was born ,was already declining .At the age of 18, my father in the army on the way to visit Duan Qirui ,murdered ,soon, mother also died because of grief .
Leaving Duan Qirui and three younger siblings, and several people have been embarrassed .Even when the prime minister ,Duan Qirui is quite simple ,always a long gown ,a skullcap .Home often flow problems ,need to borrow money to spend .
If someone gave him gifts,louboutin pas cher, he can only choose one or two worthless stay,have a career fill m, remaining all decline with thanks .Once Feng Yuxiang gave him a big pumpkin ,he left in the half to give people feel shy half ,then .
Duan Qirui did not have any real estate ,this in the Chinese history and even seems to be unique ,so they called Duan Qirui was a political officer .In 1931 the ?One eight ,the Japanese invaders occupied me ,and then attempts to control ,planning organization .
Once the pro-Japanese Duan Qirui became the object of hook in Japan ,Japan promised high position and handsome salary ,but Duan Qirui is unmoved .Should be invited ,on January 24, 1933 ,Duan Qirui a line of Shanghai ,started his life in last three years .
By 1936, Duan Qirui body was very weak ,pain ,the doctor advised him to eat some meat to enhance physical fitness ,he with people can die ,C cannot open answer ,still fresh in the same, and died .

Ability enhance human immunity but long-term inhalation of high oxygen also occurs to reduce cause alveolar exudate appear dizziness pale heartbeat and other problems More serious is oxygen poisoning was not easily discernible in 2-3 days often occurs in clinical symptoms then again to rescue tend to delay time Some home oxygen is often not noticed the inspired oxygen concentration and time think better oxygen oxygen concentration the longer the better This increases the risk of Pulmonary oxygen toxicity :1 symptoms similar to the bronchial Its performance and normally development process :initially for similar airway irritation symptoms such as bone after discomfort ( stimulation or burning sensation ) with mild cough and slowly increase ;and then the retrosternal pain and the pain gradually along the bronchial tree to spread across the chest breathing is very pain gradually aggravate appeared ;uncontrollable coughing ;rest is also accompanied by dyspnea At the onset of symptoms in the early stages of end exposed chest pain and cough within a few hours to reduce 2 signs :auscultation of the lungs often without obvious positive signs ;later when the symptom is serious can appear scattered crackles or Oxygen pressure is higher the symptoms and signs of latencies shorter 3 laboratory examinations :the X-ray examination can be found :lung markings thickening or pulmonary patchy shadows The spirometry :reduction of pulmonary oxygen toxicity is the most sensitive index Convulsive type of oxygen poisoning :convulsive type of oxygen poisoning performance generally can be divided into four consecutive phases :the latency :latency associated with inhalation of gas oxygen pressure was negatively related to but not a linear Oxygen pressure and shortened the latency The prodromal stage :manifestations include :①facial ticsthe most common mainly for facial and oral fibrillation ;②autonomic symptoms:sweating salivation nausea vomiting dizziness palpitations and pale ;③sensory abnormalities: can have visual field visual hallucination auditory hallucinations olfactory mouth odor and acral numb ;the emotional abnormality :irritability anxiety or euphoria ;⑤prodromalperiod can appear extreme fatigue and dyspnea few cases may have occurred Timely detection of prodromal symptoms and take immediate measures from hyperbaric oxygen environment to prevent oxygen convulsion is very important Note that in specific patients often appear only one item or several items of prodromal symptoms sometimes even without significant prodromal symptoms directly convulsions The convulsion period :prodromal period soon appear convulsion ① grand mal epilepsysample generalized tonic or clonic spasm each lasting about 2 min ;in one episodes sometimes gave a short scream unconsciousness sometimes accompanied by incontinent ;③EEG changes:appears in the convulsions occurred before increase of voltage and frequency speed appearance of spines wave and Clostridium wave ( spindle-like waves ) The coma stage :if the occurrence of seizures after remained at high oxygen environment namely into coma stage The experiment is in occasional local slight twitch dyspnea aggravated gradually continue until the cessation of breathing Personnel in the convulsions after even the timely from hyperbaric oxygen environment also have a long time confusion or mental and behavioral disorders generally 1 ～ 2Hcan be restored after a few hours sleeping No significant sequelae The pathogenesis is not completely clear Mainly has the following several points :the effect of hyperbaric oxygen on the organization the direct toxic effect When we can find no more specific mechanisms of injury temporarily consider is the oxygen to the direct toxic effect The impaired in aerobic conditions alveolar wall ( type II cells ) within the lamellar body membrane damage synthesis secretion and function decreased resulting in increased pulmonary leading to atelectasis The enzyme inhibited under hyperbaric oxygenation of many enzyme activity such as and Na+-K+-ATP enzyme inhibition The role of oxygen free radicals of oxygen is a highly reactive oxygen-containing groups Normal the body produces oxygen free radical by in vivo clearance The body was exposed to hyperbaric oxygen resulting in excessive oxygen free radicals and greatly exceed the antioxidant system removal ability Oxygen free radical damage caused by the following two aspects :1 Biological membrane ;2 :destruction of the polypeptide chain enzymes are proteins its activity is affected At the molecular level to explain many phenomena of oxygen poisoning The neural and humoral factors in the brain within certain peptides such as B endorphins and Cause of disease pathogenesis is simply said excessive inhalation of oxygen and exposure to hyperbaric oxygen pressure and duration of oxygen toxicity is caused by two main factors 1 diving breathing high partial pressure of oxygen in the use of light diving equipment diving exceed the specified depth The use of air ventilation type diving equipment diving underwater for too long it with helium oxygen equipment for large diving depth if not in accordance with the provisions of the preparation of the corresponding oxygen concentration in the gas mixture or mistakenly relatively shallow suction using the gas in the depths of the use of 2 pressurized cabin breathing hyperbaric oxygen :exceeding the prescribed pressure time limit Influence factors of the individual differences and individual differences :on different individuals of high concentration oxygen sensitivity varies greatly Even in the same individual the oxygen tolerance in different state of great fluctuation The increase of CO2 concentration in the inhaled gas :promoting hyperbaric oxygen induced convulsion labor intensity:labor intensity increase so that oxygen poisoning :high temperature can reduce the organism to hyperbaric oxygen tolerance Low temperature to a certain extent can increase the tolerance but if too low to cause muscle tremors energy consumption increases then the tolerance will be reduced The mental factors :emotional mental stress lack of sleep can reduce the organism to hyperbaric oxygen tolerance Diving oxygen poisoning in rapidly leave the high pressure of environmental : the emergence of prodromal symptoms immediately when the rising water have convulsions when should be timely sent divers to rescue but to control the rate of rise ( < ;10 m/min ) to prevent pulmonary barotrauma The water after treatment :removable equipment lying to rest quiet pay attention to keep warm continue to observe anti convulsion The anticonvulsant treatment of convulsions :medication should be selected on the heart and lung function was less affected by the drug used 4% chloral hydrate enema 50ml 2 h after subcutaneous injection can be used repeatedly do not exceed 4 doses per day Can also be intramuscular or intravenous injection of 02 ～ 03 gamobarbital Because the oxygen convulsions often accompanied by a certain degree of lung injury disabling effects of inhalation anesthetics A pressurized cabin oxygen poisoning on through a face mask oxygen cabin rapid removal of masks breathing air cabin and according to the conventional decompression In the pure oxygen cabin first with compressed air for ventilation reduce the cabin and then gradually decompression cabin The onset of convulsions should pay attention to the following points :①prevent fallsfall or tongue is bitten through if necessary the use of antispasmodic agents ② should pay attention topatients seizures easily occur when the laryngeal spasm while breath-holding now unable to decompress to prevent the glottal closure caused by pulmonary barotrauma Only the rhythmic respiratory recovery patency after that according to the provisions of decompression ③ leavehyperbaric oxygen environment still have convulsions to anticonvulsant therapy On pulmonary oxygen toxicity light back to the normal environment after a few hours can be restored ;in severe cases pulmonary X-ray monitor a few days can be recovery The two type of oxygen poisoning have lung injury should the routine use of antibiotics Cerebral oxygen intoxication initially frontal nasal eye lip and cheek muscle fibrillation can also affect the small muscles of the hand ;pale sense of smell Then can have disgusting vomiting dizziness sweating salivation abdominal tension ;also can appear the loss of vision visual field The ten thing you I incapable of action thing in lifevisual hallucination auditory hallucinations ;there will be a slow heartbeat palpitations choke means (toe) side pins and needles mood abnormality ( anxiety depression irritability or pleasure ) And then there are extreme fatigue sleepiness and difficulty in breathing A few cases may also occur Type of oxygen poisoning mainly atrophy In a preterm infant incubator oxygen time is too long the retina has extensive vascular obstruction tissue infiltration retrolental fibroplasia can be so blind Prevention can be very good prevention on one hand to strengthen the usual for relevant personnel education make the oxygen poisoning symptoms especially the prodromal symptoms aware and alert on the other hand with the oxygen in the process we must strictly observe the rules of operation Specific prevention measures have the following several aspects The oxygen sensitive test ( oxygen susceptibility test ) let subjects under 280 kPa for 30 min pure oxygen such as the onset of seizures in prodromal symptoms then oxygen sensitive test positive not selected as the diver or submariners The strict control of oxygen - time ( pressure-duration limitation ) The intermittent oxygen ( intermittent oxygen exposure ) is oxygen in stages at the time of the two oxygen between 5 ~ 10 min suction air The fact proves the shorter interval time can prevent longer oxygen time may lead to oxygen toxicity thus extending the total duration of oxygen and to maximize the use of oxygen purpose The control factors of ensuring oxygen supply equipment in good condition strict operation regulations of understanding of divers or the patients work and rest system and mental state of the oxygen minimize unnecessary ④during oxygen inhalationmedical staff should pay close attention to in order to find the timely processing Effect of oxygen oxygen effect and exposure due to the partial pressure of oxygen in the height or the presence or absence of the biological effects of fluctuation phenomenon ( GSch Warz ( 1909) in the oppressive skin to promote blood circulation obstacles that can make the skin radiation damage reduced oxygen effect this is the artificial control of radiation effects in the earliest examples From higher organisms can see this kind of phenomenon explain the radiation indirect effects intracellular generation of free radicals and the material response is subject to the influence of oxygen The radiation of high ( LET αproton ) oxygen effect is not significant In fact oxygen is catalytic aging material when the air is to achieve a certain number will oxygen poisoning Oxygen is also leads to cell mitochondrial mutations in the arch-criminal of Effect of oxygen on the medical application of oxygen in radiation biology effect is of great significance in a hand As early as 1921 Holthusen had noticed when deoxygenated Ascaris eggs on a certain antagonism In 1953 Britain LH and his colleagues made the first oxygen effect immediately aroused the great attention of the radiation biologist As mentioned above ionizing radiation produced in the process of all kinds of damage caused by organisms If the presence of oxygen oxygen and free radical function of R and organic radical R00 R00 is the target substance which can not be repaired in the form of The irradiated material chemical composition changes If no oxygen is present the reaction is not produced and a lot of ionized target molecules can repair From this sense oxygen can be considered to fixed radiation injury this is called oxygen effect Oxygen effect the exact mechanism of action is not fully understood but the views are also different but that the role of oxygen free radicals in this are consistent Clinical radiologists have been attached to oxygen effect on radiation sensitivity in vitro and have been found in practice it has a larger role for radiotherapy Is the development of oxygen free radicals in anticancer therapy the drugs used for hydrogen peroxide H202 it enters the human body the most important step in the reaction is generated under the action of catalase CAT water and release oxygen Most people only see the O2 can increase the oxygen supply alleviate hypoxia increased tissue oxidative energy supply Results in H2O2 anticancer therapy the O2 also in free radical damage cancer cells after the injury fixed making it impossible to repair increased the mortality rates of cancer cells So H2O2 anticancer has two aspects :① themechanism of oxygen free radicals attack cancer cells causing injury ;②oxygen effectwill damage fixed H2O2 not only provides oxygen free radicals but also to provide oxygen is a rare Now being studied to increase tissue oxygenation measures :①in hyperbaric oxygen chamber for radiotherapy II during irradiation at atmospheric pressure at the same time for the patient to inhale oxygen containing 95% and 5%CO2 can cause respiratory frequency increased induce peripheral vasodilation increased oxygen diffusion ③ using transfer modifiers such as fluorocarbon emulsion ( FC ) Because it can carry large amounts of oxygen and can get into tumor tissue hypoxia zone and release oxygen ④ oxygen carrying capacity enhancement compounds such as BW12C BW589C ⑤ such as cinnamon benzene of chant fluorine chant through inhibition of cellular respiration and to enhance the role of oxygen in tumor cells ⑥ each time after irradiation using hypoxic cells into cells of oxygenation using small dose fractionated irradiation Dissolved oxygen oxygen in the air to become dissolved oxygen dissolved in The dissolved oxygen content and the oxygen in the air the partial pressure of water are closely related In natural conditions changes in the oxygen content of little so the water temperature is the main factor the lower the water temperature the higher the content of dissolved oxygen in water Dissolved oxygen is dissolved in water the amount of oxygen usually written as DO per liter of water with the oxygen in the Mg numbers The dissolved oxygen in the water is a measure of how many water purification capacity as an indicator It with air oxygen partial pressure atmospheric pressure temperature and quality are closely related In 20 ℃ 100kPa dissolved oxygen in the water about 9mg/L Some in the aerobic bacteria under the effect of biological degradation to consume the water dissolved oxygen If time calculation according to the C+O2=CO2 know every 12g carbon to oxygen consumption 32g When dissolved oxygen value to 5mg/L some fish breath difficulty The water dissolved oxygen due to oxygen into the air and green aquatic plants will continue to be added But when the water polluted by organics oxygen consumption and serious dissolved oxygen cannot get seasonable complement anaerobic bacteria in the water body will soon breed organic matter from the corruption that water turned black smelly Study on the water self-purification capacity value is a basis The water dissolved oxygen is consumed to restore to the initial state for a short time the self-purification ability or water pollution is not serious Otherwise water pollution is serious self-purification ability is weak or even lose the self-purification ability Related information is the main component of the air with oxygen A lot of oxygen compounds for example mercuric oxide in heating would release oxygen All the elements in the earth is oxygen content of the largest These are very early oxygen may be people But because oxygen is normally to gas condition exists and can be exposed to visible solid liquid so that people only by intuition observation cannot recognize it Begin from sixteenth Century in many researchers on heating oxygen containing compounds gases obtained on air in the combustion of the material and animal respiration in the role was in early scientific experiment and thus only the discovery of oxygen It is in the understanding to combustion oxygen was found was demolished Through the experiment to determine the combustion gases in promoting substance material is a kind of element called it oxyg è ne( French English as oxygen ) This word comes from the Greek oxyS ( acid ) and gene (production life source ) namely acid source Air in the other part is called the azote comes from the Greek a ( no ) and Zoe ( life ) is not capable of sustaining life leaving only a historical term .must not make colonialism tail drag to
