Objective: To explore the treatment technique, occurrence and development patterns of such radiation injuries as in a major radiological accident in which a victim suffered mild bone marrow radiation sickness combined grade degree Ⅲ acute radiation induced skin injury, based on his dose estimation, clinical manifestations and disease treatments. Methods: History inquiry in detail, earlier physical dose estimation and biological dose estimation were conducted in conjunction with analyzing the chromosome aberration of peripheral blood lymphocytes. The physical dose was estimated by Monte Carlo method.The systematic laboratory and imaging examination was performed to evaluate the condition. The comprehensive analysis was conducted to determine the diagnosis and treatment plan. Results: At 3d after the exposure, "Ren" felt mild pain and discomfortable on the skin of the right index finger. The body of the right hand index finger was covered with blister at 21 d after exposure.The estimation of biological dose was 0.43 Gy (95%CI: 0.31-0.58 Gy), and the physical dose was estimated to be 36-164 Gy for each part of the right hand finger. The hematopoietic system, immune system and endocrine system were normal. The liver function index value was transiently increased. The liver damage resulted from the use of antibiotic-induced combined with the patient′s past medical history and admission examination result, and the relevant antibiotics were discontinued. The liver function returned to normal after liver protection treatment. At 22 d after irradiation, a right finger incision and decompression surgery were performed. The stem cells were extracted and implanted into the right index finger. After 59 days of hospitalization, there was no obvious discomfort in the body, and the right index finger recovered well, as well as the pain significantly relieved, and the knuckle activity was basically normal. Conclusions The patient with excessive radiation and grade Ⅲ acute radiation skin injury was successfully treated, and local application of autologous adipose-derived stem cell transplantation achieved good result .

In the research community, resistance to apoptosis is often considered a hallmark of cancer. However, pathologists who diagnose cancer via microscope often see the opposite. Indeed, increased apoptosis and mitosis are usually observed simultaneously in cancerous lesions. Studies have shown that increased apoptosis is associated with cancer aggressiveness and poor clinical outcome. Furthermore, overexpression of Bcl-2, an antiapoptotic protein, is linked with better survival of cancer patients. Conversely, Bax, CD95, Caspase-3, and other apoptosis-inducing proteins have been found to promote carcinogenesis. This notion of the role of apoptosis in cancer is not new; cancer cells were found to be short-lived 88 years ago. Given these observations, resistance to apoptosis should not be considered a hallmark of cancer.

Objective To investigate the relationship between atherosclerotic lesions of arteries of lower extremities and metabolic disorders in patients with diabetic foot. Methods Three hundreds and sixty two patients with type 2 diabetes were selected, including 232 males and 130 females, with average age of (64.9?11.2) years and the average diabetic duration of (9.2?7.5) years. Atherosclerotic lesions of the arteries were detected by type B ultrasound. According to severity of lesions of femoral, popliteal and tibial arteries, the patients were classified into four groups: A-control group, B-plague formation (plague), C-arterial stenosis (stenosis) (luminal narrowing≥50%) and D-arterial occlusion (occlusion). Fasting blood glucose, GHbAlc and lipid levels (Total cholesteral, TC; Triglyceride, TG; Low density iipoprotein, LDL) were tested in all patients. Results (1)GHbAlc levels in group B and group C were significantly different from that in group A respectively[(8.4?2.2%)vs(7.8?2.2%),P

Objective To survey avian influenza A viruses (AlVs) in the environment and explore the reasons for the surge in human H7N9 cases.Methods A total of 1,045 samples were collected from routine surveillance on poultry-related environments and 307 samples from human H7N9 cases-exposed environments in Henan from 2016 to 2017.The nucleic acids of influenza A (Flu A),H5,H7,and H9 subtypes were detected by real-time polymerase chain reaction.Results A total of 27 H7N9 cases were confirmed in Henan from 2016 to 2017,24 had a history of live poultry exposure,and 15 had H7N9 virus detected in the related live poultry markets (LPMs).About 96％ (264/275) Flu A positive-environmental samples were from LPMs.H9 was the main AIV subtype (10.05％) from routine surveillance sites with only 1 H7-positive sample,whereas 21.17％ samples were H7-positive in H7N9 cases-exposed environments.Samples from H7N9 cases-exposed LPMs (47.56％)had much higher AIVs positive rates than those from routine surveillance sites (12.34％).The H7+H9 combination of mixed infection was 78.18％ (43/55) of H7-positive samples and 41.34％ (43/104) of H9-positive samples.Conclusion The contamination status of AIVs in poultry-related environments is closely associated with the incidence of human infection caused by AlVs.Therefore,systematic surveillance of AlVs in LPMs in China is essential for the detection of novel reassortant viruses and their potential for interspecies transmission.

OBJECTIVETo culture, isolate and identify new bunyavirus in Vero cell line.

METHODSSamples of 164 new bunyavirus positive by real time RT-PCR detection and well preserved serum specimens were selected from cases of fever, thrombocytopenia and leukopenia syndrome (FTLS) in Xinyang, Henan province in 2009 - 2011. These sera were cultured in Vero cell line and new bunyavirus were detected by observing cytopathic effect (CPE), Real-time RT-PCR, indirect immunofluorescence assay (IFA) and thin-section electron microscopy observation. A total of 10 positive PCR products were selected randomly for sequencing and the results were compared with sequence in Genbank.

RESULTSAmong 164 FTLS serum specimens cultured in Vero cell line, no special CPE were observed and 67 strains (40.85%) were positive detected by Real-time RT-PCR. Nucleic acid similarity of 10 specimens were 97.8% - 100% and there's also a high similarity (> 99%) between specimens and new bunyavirus isolates (Accession No. HQ141600.1). Among 67 positive strains, 58 of them showed specific fluorescence particles by IFA. The viral particles were observed to be spheres with a diameter of 80 - 100 nm by electron microscopy.

CONCLUSIONVero cell line is suitable for culture, isolation and identification of new bunyavirus.

OBJECTIVETo develop an indirect immunofluorescence assay (IFA) for detection of IgG antibodies against new bunyavirus.

METHODSThe antigen slides were prepared with 5 new bunyavirus strains isolated using Africa green monkey kidney (Vero) cells. Specificity and sensitivity evaluation of IFA were carried out by optimizing working conditions of IFA. Using established IFA, serum samples from both acute and recovery phases were tested for 126 cases with fever thrombocytopenia and leukopenia syndrome in Xinyang, Henan province in 2007 - 2011. The results were compared with detections by RT-PCR.

RESULTSThe new bunyavirus stable immunofluorescence specific WZ69 strain was selected to prepare antigen slides of IFA. The optimum conditions of IFA were: optimum dilution for primary antibody (serum) and secondary antibody (isosulfocyanic acid fluorescence marked goat anti-human IgG antibody) was 1:40 and 1:150 respectively. The optimum dilution for Evans blue in secondary antibody was 1:20 000. Among the 126 patients, 96 paired serum specimens were tested positive to the new bunyavirus and 30 patients were tested negative to the virus. The positive rate of antibodies was 76.19%. There was no significant difference in results between IFA and RT-PCR (72.22% (91/126)) (P > 0.05).

CONCLUSIONThe IFA has high sensitivity and specificity with easy operation. It can be used in detecting the new bunyavirus infection in patients with fever, thrombocytopenia and leukopenia syndrome.

Objective: To investigate the current practice of extracorporeal cardiopulmonary resuscitation (ECPR) for Chinese cardiac arrest patients after the publication of 2015 American Heart Association guidelines for cardiopulmonary resuscitation. Methods: A questionnaire was distributed to healthcare providers of emergency departments (EDs) and/or Intensive Care Units (ICUs) across 52 hospitals in China from August to November 2016. Data collection ended in February 2017. The questionnaire included three parts: (1) characteristics of the departments and the respondents; (2) knowledge about ECPR; (3) practice of ECPR in cardiac arrest patients (case volume, inclusion/exclusion criteria, ECPR procedure). The characteristics of the departments/hospitals were only answered by the head of the department. Results: A total of 1 952 (86.8%) respondents fulfilled the survey. Only 2.5% of the respondents from 3 of 52 hospitals performed ECPR. Among the three hospitals, the case number of ECPR were ≤5 per year and none of them had written ECPR procedures. Only one hospital had formal inclusion/exclusion criteria. The inclusion criteria included age between 18 to 60 years, suspected cardiogenic cardiac arrest, beginning of cardiopulmonary resuscitation <5 min after cardiac arrest and duration of cardiopulmonary resuscitation >10 min. The top three reasons for the nonuse of ECPR were unknown fields (31.2%), potential ECMO-related side effects (26.9%) and cost (18.7%). Conclusions: ECPR for cardiac arrest patients are not well understood by healthcare providers in the emergency department or ICUs and its application is still in the early stage in China. Educational training and other interventions are needed to promote the clinical practice.

A large number of epidemiological data have shown that the high-density lipoprotein cholesterol level is negatively related to atherosclerotic cardiovascular disease, suggesting that high-density lipoprotein may have the effect of anti-atherosclerosis. It may play the role of anti-atherosclerosis, through the promotion of cholesterol reverse transport, anti-inflammatory, antioxidant, and against thrombosis and fibrinolysis and so on. Among them, reverse cholesterol transport which is mainly regulated by apolipoprotein A-I, ATP-binding cassette transporter 1, liver X receptor and cholesteryl ester transfer protein, may play a major role in the maintenance of cholesterol homeostasis and reversing the course of atherosclerosis. These regulatory factors may be potential targets in high density lipoprotein-based drug discovery. In this review, these key proteins are discussed for the current status of small molecule drugs against atherosclerosis.

With the introduction and development of evidence-based medicine in China, it has been spread rapidly in the area of integrative medicine (IM) and has become a new unique discipline. During almost 20 years, as one of the most important parts of evidence-based IM, systematic review (SR)/meta-analysis (MA) of IM have shown a good development momentum in the aspects of quantity, depth, breadth and influence, but also face the harsh situation of the uncontrolled quantity and quality, especially for SRs in Chinese. Therefore, how to supervise and standardize this area effectively becomes a problem to be solved. Based on the experience both at home and abroad, the authors put forward several kinds of solutions for laying the foundation for further development such as promoting the registration system of SR/MA of IM, effectively setting up the regulatory platform of quality and quantity, launching professional training for SR/MA reviewers, forming qualification registration, developing the data transfer and sharing platform to realize the transparency of evidence process.
