1.THE MEASUREMENT OF NEUTROPHIL FUNCTION AND OPSONIC ACTIVITY BY CHEMILUMINESCENCE
Medical Journal of Chinese People's Liberation Army 1982;0(03):-
A method for measurement of neutrophil function and opsonic activity by chemiluminescence (CL) was reported in this paper.The factors influencing the emission of CL were discussed. The experimental results suggested that CL depends on the concentration of luminol, the dilution of serum opsonin, the number of neutrophils and the environmental temperature. The optimum conditions defined in present study were: the concentration of luminol was 1?105M, the number of neutrophils 2?106/mml, the reactive temperature 37℃. According to the relationship between CL emission and the bactericidal activity of phagocytizing neutrophils, the measurement of CL may be used as a rapid, simple and usefull tool to determine the funetion of humoral-phagocyte axis.

Patients with ischemic stroke is often accompanied by inflammtory response. Studies have suggested that toll-like receptor 4 (TLR4) has induced the occurrence,development and of ischemic stroke and secondary brain injury. This article reviews the toil-like receptor 4 signal transduction pathway and its roles in ischemic stroke in order to provide certain basis for the development of TLR4-targeted medication.

Objective To investigate clinical significance and related factors of fluid-attenuated inversion recov?ery vascular hyperintensities (FVH) in transient ischemic attack (TIA) of carotid system. Method Data including general information and TIA risk factors was continuously collected from 142 patients with carotid system TIA from the depart?ment of neurology of Sheng jing Hospital affiliated China Medical University from January 2012 to February 2014.All pa?tients completed brain MRI including FLAIR and diffusion-weighted imaging (DWI)and MRA examinations within 72 hours after TIA. All patients were followed up for one month. Risk factors and FVH situations were analyzed based on clinical manifestations and DWI results. Result There were 87 male cases (61.27%)and FVH positive 57 cases (40.14%) among 142 cases with carotid system TIA (mean age 63.2±11.5). Logistic regression analysis revealed that the large intra?cranial carotid artery stenosis≥50%(OR=2.44,95%CI:1.09~5.49, P=0.03) and prior history of ischemic stroke (OR=3.88,95%CI:1.04~14.5, P=0.04) were independently associated with positive FVH. At one month followed-up, 40 cas?es (28.17%) of 142 patients progressed to acute cerebral infarction. Vulnerable plaque number in the contralateral carot?id artery (P=0.018), contralateral intracranial large vessel stenosis in MRA≥50%(P=0.007) and contralateral FVH oc?currence rate (P=0.001) were significantly higher in cerebral infarction group than in non-cerebral infarction group. Con?clusion FVH is common in carotid TIA patients, which is associated with intracranial carotid artery stenosis ischemic and previous history of ischemic stroke. Vulnerable plaque number of contralateral carotid artery, contralateral intracranial large vessel stenosis≥50%and the rate of occurrence of contralateral FVH may be associated with short-term progress leading TIA to acute infarction.

This paper explored factors influencing initiatives of clinical teachers in millitary medical university for training clinical undergraduates including work pressure after being transferring to civilian,work pressure,policy orientation,economic pressure,student factor and psychological factor,etc. Meanwhile,this paper explored the incentive mechanism of clinical teachers in millitary medical university for training clinical undergraduates including training and evaluating clinical teach-ing teachers, innovating evaluation criterion and creating sustainable teaching atmosphere (building examples and establishing various incentive systems). All measures taken above was mean to inspire the initiatives of clinical teaching teachers and to ensure the quality of clinical teaching.

At present, the formal bariatric surgery approved by the American Society for Metabolic and Bariatric Surgery (ASMBS) includes adjustable gastric banding (AGB), sleeve gastrectomy (Sleeve gastrectomy, SG). ), Roux-en-Y gastric bypass (Roux-en-Y gastric bypass, RYGB), biliopancreatic diversion with duodenal switch (BPD-DS), mini gastric bypass (Mini-gastric bypass, MGB), single anastomosis gastric bypass (OAGB) and partial endoscopic surgery. According to the Chinese Society for Metabolic and Bariatric Surgery (CSMBS), the Chinese Obesity and Metabolic Surgery Database (COMES Database), and the Chinese Obesity and Metabolic Surgery Database (COMES Database), the Chinese Society for Metabolic and Bariatric Surgery (CSMBS) Chinese Obesity and Metabolic Surgery Collaborative, COMES Collaborative), Shanghai Weight Loss and Diabetes Surgery Data Management System, Shandong Province Weight Loss and Metabolic Surgery Case Registration System, Jiangsu Province Weight Loss and Metabolic Surgery Data Registration System, Great North China Weight Loss and Metabolic Surgery Statistics from the clinical data database and the Greater China Weight Loss and Metabolic Surgery Database. The domestically developed and approved bariatric surgery methods include RYGB, SG, MGB, OAGB, BPD-DS, AGB, combined sleeve gastrectomy (SG Plus), Jejunoileal Bypass (Jejunoileal Bypass, JJB), single stoma duodenal transposition (SADI-S), intragastric balloon (Balloon). However, there are still some irregular bariatric surgeries in China, which will cause some uncommon complications and bring great pain to patients. At the same time, it is also a huge challenge for regular bariatric surgeons who perform corrective surgeries. This article will review the revision surgery after bariatric surgery in China in the past 20 years, discusses a series of problems caused by non-standard bariatric surgery and the development of regular bariatric surgery.
