Objective To explore the strategy of emergency medical rescue of the massive crowd in general hospital during spring festival with snow disaster. Method The clinical data of 20 966 emergency cases were analyzed retrospectively from 22 Jan,2008 to 6 Feb, 2008 with snow disaster, and concerned about the ratio of different diseases, the character of pre-hospital care and the contrast between emergency medical treatment and routine work. Results The accidence of respiratory disease ( 57.3 % ) was followed by gastrointestinal ( 25.5 % ) and trauma (6.2% )during the emergency medical treatment, and surgical trauma, syncope, coma and convulsion were the most common symptoms, also in some conditions, but empties returning was 30.3% . Similar to the above situation, the extremities (56%)and head injury (24%)were most commonly in the hospital emergency department. The incidence of falling accidents was high( 35.7 % ), and two of them were dead due to trauma on died of being trampled, and on the other was electrothermal burn and falling. Conclusions The general hospital is very important in emergency medical treatment, and it should be ready to tackle the emergency disaster, in order to reduce the loss to minimum.

Objective To study the epidemiologic characteristics of trauma in the prehospital first-aid in megapolis. Methods The epidemiologic data of 10 654 traumatic patients,including treated by prehospital treatment and emergency treatment from January 2000 to January 2005,were analyzed.Results The proportion of male was 70.96%,adult patients(21~50 years old)79.23%,suburb 62.86%,downtown 37.14%.The patients whose ISS scores surpassed 16 accounted for 37.98%,which caused by traffic accident was 37.74%,by public order 24.39%,by industrial trauma 21.71%.The trauma in the limbs accounted for 67.51%,cephalic and cervical wounds accounted for 58.64%,multiple wounds 41.77%,thoracic and abdominal wounds 39.41%.Three hundred and sixty one were killed on the spot,which caused by traffic accident were 46.81%,by public order 28.81%,by industrial trauma 14.40%.Forty-two percent point six six patients died of multiple trauma,54.07% died of cephalic and cervical trauma,15.79% died of thoracic and abdominal wounds.Conclusion Suburban area gradually became the frequently-occurred areas of trauma in megapolis. The wounded were mainly young adults and had a tendency of juvenility.The majority of damaging and lethal factors were traffic accident,public order and industrial trauma.Some pertinet measures and professional first-aid models may improve the traumatic first-aid level.

Reprogramming of energy metabolism is one of the basic characteristics of cancer and has been proved to be an important cancer treatment strategy. Isocitrate dehydrogenases (IDHs) are a class of key proteins in energy metabolism, including IDH1, IDH2, and IDH3, which are involved in the oxidative decarboxylation of isocitrate to yield α-ketoglutarate (α-KG). Mutants of IDH1 or IDH2 can produce d-2-hydroxyglutarate (D-2HG) with α-KG as the substrate, and then mediate the occurrence and development of cancer. At present, no IDH3 mutation has been reported. The results of pan-cancer research showed that IDH1 has a higher mutation frequency and involves more cancer types than IDH2, implying IDH1 as a promising anti-cancer target. Therefore, in this review, we summarized the regulatory mechanisms of IDH1 on cancer from four aspects: metabolic reprogramming, epigenetics, immune microenvironment, and phenotypic changes, which will provide guidance for the understanding of IDH1 and exploring leading-edge targeted treatment strategies. In addition, we also reviewed available IDH1 inhibitors so far. The detailed clinical trial results and diverse structures of preclinical candidates illustrated here will provide a deep insight into the research for the treatment of IDH1-related cancers.

Stroke at the acute stage is a major cause of disability in adults, and is associated with dysfunction of brain networks. However, the mechanisms underlying changes in brain connectivity in stroke are far from fully elucidated. In the present study, we investigated brain metabolism and metabolic connectivity in a rat ischemic stroke model of middle cerebral artery occlusion (MCAO) at the acute stage using F-fluorodeoxyglucose positron emission tomography. Voxel-wise analysis showed decreased metabolism mainly in the ipsilesional hemisphere, and increased metabolism mainly in the contralesional cerebellum. We used further metabolic connectivity analysis to explore the brain metabolic network in MCAO. Compared to sham controls, rats with MCAO showed most significantly reduced nodal and local efficiency in the ipsilesional striatum. In addition, the MCAO group showed decreased metabolic central connection of the ipsilesional striatum with the ipsilesional cerebellum, ipsilesional hippocampus, and bilateral hypothalamus. Taken together, the present study demonstrated abnormal metabolic connectivity in rats at the acute stage of ischemic stroke, which might provide insight into clinical research.
