Objective To investigate the antibacterial activity of the alkaloids extract from Oxytropis falcata Bunge against 9 common pathogens in vitro. Methods Alkaloids was extracted from Oxytropis falcata Bunge. The agar plate dilution method was adopted to evaluate the activity against bacteria of 4 Gram-negative test strains and 5 Gram-positive test strains, while the MIC and MBC were determined by tube double dilution method. Results The alkaloids extract from Oxytropis falcata Bunge had the antibacterial activity against 9 pathogens and there was a good dose-response relationship between sensitivity and concentration. Antibacterial activities against bacillus subtilis and stentrophmomas maltophilia showed stronger than other tested bacteria, the MIC and MBC were 0.95 mg/mL and 1.91 mg/mL, respectively. In other tested bacteria, MIC and MBC were ranged in 1.91-7.63 mg/mL. Conclusion The alkaloids extract showed a broad spectrum of a stronger antibacterial activity against all tested pathogens. Gram-positive strains were more sensitive than Gram-negative strains to the inhibitory effects of the alkaloids extract.

Objective To investigate the expression of brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) in hippocampus after status convulsion (SC) and explore the influence of age and duration of SC on the expression of BDNF and NGF. Methods Animal model with the different durations of SC (30 min,3h) were established by intraperitoneal injection of 3 mEq/kg lithium chloride,18-20 h later,followed by 5 mg/kg pilocarpine in 40 adult Wistar rats aged 2-3 months and 40 20-day-old Wistar rats. The normal control and experimental control were made in ten adult rats and ten 20-day-old rats (n=5 for each control). The rats were sacrificed at 3 h,6 h,12 h,1 d,3 d,7 d after 30-minute SC,or 3 h,1 d after 3-hour SC respectively. The location and cell type expression of BDNF and NGF in the hippocampus were observed by immunohistochemistry. The levels of BDNF and NGF at different time points were quantitatively analyzed by enzyme-linked immunosorbent assay (ELISA). Results The cells expressing BDNF and NGF located mainly in the dentate granule cells and CA1-CA4 pyramidal cells of hippocampus. The most positive immunoreactivity was in cytoplasm,partly in axons. The expression of BDNF had the tendency of increase in all rats after 3-hour SC,peaked at 1 d and 3 d respectively. These increases lasted for at least 7 d. Moreover,a several-fold increase was observed at the peak levels. The patterns of NGF expression were similar to that of BDNF after SC. The elevated degree and duration of NGF expression were remarkably lower than that of BDNF,declining abruptly to below control levels by 12 h with the characteristic of biphasic increase. The expression of hippocampal BDNF had the positive correlation with the duration of SC,but that of NGF was not. No matter the duration of SC,there was more rapid and evident induction of BDNF in 20-day-old rats and adult rats. Moreover,the age-related difference was more obvious for the longer duration of SC. Conclusion SC induced the expression of BDNF chiefly in hippocampus,and had minor influence on that of NGF. The expression of BDNF was related to age and duration of SC. There was a more rapid and marked induction of BDNF in 20-day-old rats and adult rats. The age-related difference had the positive correlation with the duration of SC.

Objective To study the effect and eradication of Kuiyang Decoction(decoction for ulcer) plus triad-therapy of western medicine on helicobacter pylori(Hp) positive duodenal ulcer.Methods The 140 cases were randomly divided into two groups.The control group,70 cases,was treated by standard triad-therapy:omeprazole,amoxicillin and metronidazole per os for one week in succession,then only omeprazole,20mg each time,twice a day,3 weeks in succession.The treatment group,70 cases,was treated by Kuiyang Decoction per os,one dose each day,for 4 weeks in succession in addition to taking the above-mentioned western medicines in the same way as the control group.Before and after treatment both groups were given the Hp test for comparing the therapeutic effect.Results The treatment group was better than the control group in the effect under gastroscope,Hp eradication rate,symptom improvement,and one-year recurrent rate(P

To evaluate the efficacy and safety of resection and cryotherapy combined with amniotic membrane transplantation (AMT) for the treatment of vernal keratoconjunctivitis (VKC) with giant papillae (GP). Eight patients (16 eyes involved) with VKC, characterized by GP on the upper tarsal conjunctiva, underwent resection and cryotherapy in combination with AMT. The follow-up lasted for 3-22 months. The results showed that corneal shield ulcers and superficial punctuate keratitis healed during the first week after surgery and did not recur. Fourteen eyes (87.5 %) were symptom-free 1 month after surgery, and no GP, ectropion, trichiasis and other complications were noted, but the blood vessels of upper tarsal conjunctiva could not be clearly seen and a little conjunctival scar was observed. Recurrence of GP was observed in 2 eyes (12.5 %), with the area being less and irritation milder as compared with those before the operation. Among the two eyes, one eye was treated by cyclosporine eyedrops with improvement, but the other eye showed no improvement after the treatment, and underwent a second surgery with a cotton patch soaked in fluorouracil applied onto the supratarsal area after resection and cryotherapy. Four months after the treatment the patient presented no symptoms and GP did not recur. It is concluded that the resection and cryotherapy combined with AMT is an effective and safe treatment for VKC with GP.
