Objective To observe the protection effects of sodium ?-aescinate(SA) on the nervous function in the rats with early spinal cord injury(SCI). Methods One hundred and twenty SD rats were randomly divided into four groups(n=30).Rats in the blank control group were performed laminectomy only,while those in the other three groups were injured at the level of Tl1 spinal segment by Allen's weight drop method(10 g ?10 cm) and immediately intraperitoneally given normal saline(5.0 mg/kg)(control group), SA(5.0 mg/kg)(SA group) and methylprednisolone(100 mg/kg)(MP group) once daily,respectively.After 8 h,24 h,96 h,7 d and 14 d,spinal cord function change of posterior limb were determined with Rivlin method.The rats were sacrificed and the injured segments were resected for pathological analysis. Results As time prolonged,the rehabilitation of spinal cord function with various degree could be observed in each group.Function rehabilitation was found among the rats in the control group,SA group and MP group 96 h after injury,and more rehabilitation was gained later in the latter two groups,while that was not the case in the control group.Rats in the SA and MP group gained more significant rehabilitation than those in the control group(P0.05).It was revealed by pathological analysis that no necrotic neurons was found in the blank control group,and the necrotic neurons in the SA group and MP group were significantly less than the control group at the same time points(P

AIM: To research how to separate the active component in Ligusticum chuanxiong Hort by high speed counter current chromatography. METHODS: Senkyunolide A and Z-ligustilide,the main components of volatile oil in Ligusticum chuanxiong Hort were one step separated by high speed counter current chromatography. n-hexane-ethyl acetate-ethanol-water,1 ∶ 1 ∶ 1 ∶ 1(v/v),was used as the solvent system for HSCCC. Top phase and bottom phase were respectively used as static phase and mobile phase. Optimum speed and flow rate were 900 r/min and 1. 2 mL/min respectively. RESULTS: Collected fractions were analyzed by HPLC and identified by EI-MS and 1HNMR. Purity could reach more than 95% . CONCLUSION: Lactone is fit to be separated and prepared by high speed counter current chromatography with good resolution and high purity. We find a fast and efficient way to separate these.

Objective To systematically evaluate the relationship between stroke location and post-stroke depression (PSD) in first-ever stroke patients.Methods The studies on the relationship between stroke location and PSD published from January 1980 to March 2016 were retrieved from databases,including Chinese science and technology journal full-text database (VIP),China journal full-text database (CNKI),Wanfan database,PubMed,ISI Web of Science,Ovid database and Elsevier Science Direct.RevMan5.3 software was adopted for data consolidation and analysis.Results A total of 14 studies,including 1 952 cases of patients were included.The meta analysis indicated that no direct relationship was found between stroke location and PSD in first-ever stroke patients [random effects model,95 ％CI(0.89,1.43),P＜0.01].The results of subgroup analysis indicated that the PSD was associated with the right hemisphere lesion when the Hamilton Depression Scale (HAMD) was adopted for assessment [fixed effects model,95 ％ CI(1.21,1.76),P＜0.01],while the relationships were not found in the subgroup analysis of time course after stroke and the aphasia occurrence.Conclusion Stroke location may be not directly associated with PSD,further studies are needed to ascertain the relationship between stroke location and PSD.

Objective: In acute pancreatitis, traditional treatment insists fasting on purpose to avoid activation of proteolytic enzymes and pancreatic enzyme secretion. The aim of our study was to evaluate the efficacy and feasibility of early oral feeding as compared to traditional fasting in patients with mild acute pancreatitis.Methods: Seventy-two patients were randomized to the two treatment groups, fasting or early oral feeding. The inclusion criteria were pancreas amylase≥3times above normal, onset of abdominal pain within 48h, acute physiological and chronic health evaluation-II score<8 and C-reactive protein(CRP)<150 mg/L. Measures were amylase, systemic inflammatory response, length of hospital stay. Results: The groups were comparable with respect to age, sex, etiology, APACHE II, time from onset of pain and amylase at admission. No significant differences were seen between the groups concerning levels of amylase, CRP, leukocytes, abdominal pain or number of gastrointestinal symptoms. The length of hospital stay time was significantly shorter in the oral feeding group (13 vs. 17 days; P<0.05).Conclusion: Early oral feeding would not exacerbate disease process. The differences between treatment groups for amylase or systemic inflammatory response were not obvious. In mild acute pancreatitis, early oral feeding was feasible and safe and may accelerate recovery.

AIM: To establish a quality control method of analysing Lajiao Fengshi Plaster qualitatively and quantitatively. METHODS: Capsaicin was identificated by TLC and menthol,borneol were determinated by GC Lajiao Fengshi Plaster,silica gel as plate,ligarine(60～90?C)-acetoacetate(3(∶)2) as mobile phase,0.5% solution of dichloroquinonechlorimide R in methanol R.as chromogenic agent to identificate capsaicin.The internal standard of GC,naphthalene was employed.10% PEG-20M as the stationary phase,column temperature at 150(?C,) and FID as the detector to determine methol and borneol.

The essential medium of B115 composed of 1% tryptone, 0.25% yeast extract and 0.5% sodium chloride was determined by using an orthogonal design. The orthogonal design was also employed in testing the optimum additions. It was composed of 0.1%(NH_(4))_(2)SO_(4),1.4%K_(2)HPO_(4), 0.6% KH_(2)PO_(4) and 0.1% (Na_(3)C_(6)H_(5)O_(7)). The yield of B115 cultured in optimum medium was compared with the one in essential medium. Statistic analysis showed that the growth of B115 was most significantly improved by adding K~(+)、NH~+_(4) and (Na_(3)C_(6)H_(5)O_(7)) to essential medium. The antibacterial effect of Bacillus subtilis strain B115 on pathogenic Aeromonas was studied. The results showed different antibacterial effects of B115 on different aeromonads. There were obvious antibacterial effects on BSK-10 and CL990920, while no effect on the growth of TL970424.

OBJECTIVE To investigate the inhibiting effect of Pingyangmycin on cultured vein endothelial cells in vitro and illustrate the mechanism of Pingyangmycin on treatment cavernous hemangioma of head and neck. METHODS By MTT assay,the inhibiting rates of cultured Ecv-304 cells which were managed with Pingyangmycin for 24h and 48h were compared respectively. The changes in the cell cycle,apoptosis,and Caspase 3 protein expression of the cells managed with Pingyangcin for 24h were examined by flow cytometry(FCM). RESULTS The results showed that the inhibiting rate of Ecv-304 was dependent on the concentration of Pingyangmycin. However,in the same concentration,the inhibiting effect for 24h was stronger than that for 48h. The percentage of G1 phase cells increased while the S phase decreased,but the percentage of G2 phase cells remained unchanged after managed with Pingyangcin for 24h. An apoptosis peak appeared before G1 phase. The apoptosis rate was also concentration-dependant. The expression of caspase 3 increased in every group of different concentration. CONCLUSION Pingyangmycin can possibly arrest the growth of Ecv-304 in the G1 phase through the mechanism of inducing apoptosis. Caspase 3 may play an important role in the induced apoptosis.
