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 analyze the effects of dopamine and norepinephrine on blood oxygen,heart rate and internal environment in patients with septic shock.Methods 80 patients with septic shock were collected.The patients were randomly divided into two groups.The control group was given dopamine treatment,the observation group was given dopamine and norepinephrine.Results The heart rate (HR)[(90.39±15.29)/min],ScVO2 index[(77.03±7.68)％] of the observation group were better than those of the control group (t=4.122 5,2.141 5,all P＜0.05).The urine volume[(94.05±22.39)mL/h],creatinine clearance rate[(53.12±14.45)mL/min] of the observation group were better than those of the control group (t=3.660 6,2.023 2,all P＜0.05).ConclusionDopamine combined with norepinephrine has significant effect on patients with septic shock,which can effectively improve the HR,ScVO2,urine volume,creatinine clearance rate and other indicators,thus to restore the patients'' internal environment.

Objective To explore the clinical effectiveness and safety of percutaneous vertebral augmentation with the Vessel-X bone void filling container system (Vesselplasty).

After procedure, the pain relief, the fracture reduction, and the cement distribution in the vertebra were observed. Results All the 3 cases were treated with the unipediclar injection technique. The operative time was 45, 32 and 30 min, respectively. The hemorrhage volume was

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.

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.

Objective To investigate the effects of eritoran on the expressions of the inflammatory cytokines interleukin-1β (IL-1β),tumor necrosis factor-α (TNF-α) and interferon-[ (IFN-β) mRNA in the basilar artery after subarachnoid hemorrhage (SAH) in rabbits.Methods Atotal of 36 healthy adult male New Zealand white rabbits were randomly allocated into three groups:SAH (n =12),normal saline (n =12) and eritoran (n =12) groups.A SAH model was induced by injection of autologous arterial blood into cisterna magnatwice.An equal amount of cerebrospinal fluid was displaced with the saline in the normal saline group.An equal amount of autologous non-heparinized arterial blood was injected immediate after the replacementof cerebrospinal fluid in the SAH group.Eritoran 1.5 mg/kg was injected intravenously immediately after the blood injection via the cisterna magna each time in the eritoran group.The food intake and neurological deficit were assessed.The expressions of IL-1β,TNF-α and IFN-β mRNA in the basilar artery were detected by real-time fluorescence quantitative polymerase chain reaction.Results The food intake scores (1.20 ± 0.41 vs.2.20 ±0.61; t =53.073,P =0.002),the neurological deficit scores (1.46 ± 0.32 vs.2.6 ± 0.08; t =306.431,P =0.001),the expressions of IL-1β (1.22 ±0.48 vs.2.38 ±0.06,P =0.000),TNF-α (1.39 ±0.07 vs.3.32 ±0.21,P =0.000) and IFN-β (1.51 ±0.08 vs.2.18 ±0.05,P =0.000) in Eritoran group were all significantly lower than those in the SAH group.Conclusions Eritoran may downregnlate the expressions of inflammatory cytokines IL-1β,TNF-α and IFN-β mRNA in the basilar artery after SAH in rabbits,increasing food intake,and improving neurological deficits.

The conventional therapy for arteriosclerosis obliterans (ASO) is Western medicine. However, it has some adverse effects and does not respond to some patients, and it is also very expensive.

Telomeres are protective caps located at the ends of human chromosomes. Telomeres shorten with each successive cell di-vision in normal human cells, whereas they are continuously elongated by human telomerase in over 85%of tumors. This simple and attractive difference steers the development of anticancer drugs targeting telomeres and telomerase. Many promising current telo-mere/telomerase-targeting agents, such as GRN163L and GV1001, showed good therapeutic effect both in preclinical studies and phaseⅠ/Ⅱclinical trials. These agents have even entered phaseⅢclinical trials in patients with various tumors. Most therapeutics are more effective when used in combination with standard chemotherapies. Moreover, pharmacological interference with tumor-cell telomere biology to reduce telomere length and/or telomere stability could enhance the effectiveness and safety of radiotherapy. Therapeutics targeting telomere/telomerase may play a key role in radiotherapy in the era of personalized medicine in the future.
