China Pharmacy 2001;0(11):-
OBJECTIVE: To assess the efficacy and safety of Sanjin tablets in the treatment of urinary tract infection. METHODS: Retrieved from electronic databases and references literatures by on-line or manual way, RCTs about Sanjin tablets in the treatment of urinary tract infection were collected. Related data were obtained and analyzed with evidence-based medical software statistically. RESULTS: 1 046 patients in 13 studies with were included. Two studies showed that Sanjin tablets had better effect than amoxicillin, ciprofloxacin, erythromycin and norfloxacin in the treatment of urinary tract infections. One study showed there was no significant difference in efficacy of Sanjin tablets and Modified juling tang. Other trials showed that there was no difference in efficacy between Sanjin tablets and Chinese herbal medicine, antibiotics. Three trials showed Sanjin tablets combined with Chinese herbal medicine or antibiotics had the same effect with antibiotics alone in the treatment of urinary tract infection. No severe ADR induced by Sanjin tablets was found in included studies. Funnel plot which assumed asymmetry indicated the existence of publication bias and unsatisfactory methodological quality. CONCLUSION: Few trials show efficacy of Sanjin tablets are better than antibiotics. Most of studies show that there is no significant difference between Sanjin tablets and antibiotics. At present no evidence indicate that efficacy of Sanjin tablet is superior to other drugs. The methodological quality of clinical trials of Sanjin tablets for urinary tract infections should be improved.
2.The influence of anisodamine on the cerebral blood flow in uncompletely ischemic rat brains
Chinese Pharmacological Bulletin 1986;0(04):-
The influence of anisodamine on the cerebral blood flow in the uncompletely ischemic brains was studied with radioactive biomicrosphere assay. After the bilateral carotid arteries were occluded the cerebral blood flow drawmatically decreased and middle part of the hemisphere had the most severe reduction. Anisodamine 10mg ? kg-1 iv selectively increased the cerebral blood flow in this area and 20mg ? kg-1 increased that in the whole hemisphere. When it was used in the dose of 40mg ? kg-, the increasing effect on the cerebral blood flow became weaker. While the cerebral blood flow decreased, the myocardial blood flow increased significantly after bilateral carotid artery occlusion. Anisodamine 20mg ? kg-1 iv made it further increase and 40mg ? kg-1 iv made it decrease. The cardiac index was not influenced by bilateral carotid artery occlusion and anisodamine 10~20mg ? kg-1 iv, but was significanntly increased by anisodamine 40mg ? kg-1 iv. These results suggested that anisodamine may be used in the treatment of ischemic cerebral diseases and should be used in different doses according to different purposes.
3.Effect of Recombination Human Erythropoietin on the Apoptosis of Glutamate-induced Retinal Cells
Acta Medicinae Universitatis Scientiae et Technologiae Huazhong 2014;(2):227-230
Objective To study the protective effect of recombination human erythropoietin (rhEPO) on the apoptosis of retinal neurons induced by glutamate.Methods The primary retinal neurons of postnatal SD rats were cultured in vitro for 7 days and divided into 3 groups :control group ,glutamate group and rhEPO pretreatment group.The neurons in the rhEPO pre-treatment group were afterwards allocated to three subgroups in terms of different rhEPO treatments (0.15 ,0.30 or 0.50 U/mL rhEPO for 12 h).Those in glutamate group and rhEPO pretreatment group were treated with glutamate at the concentration of 20μmol/L for 30 min for establishment of the apoptosis model.Twenty-four h later ,the apoptosis index (AI) was assayed by TUNEL and the expressions of BCL-xL mRNA and protein was detected by RT-PCR and immunocytochemistry respective-ly.Results The AI was significantly higher in the glutamate group than in the control group (P<0.01).The AI was signifi-cantly reduced ,and the expression level of BCL-xL mRNA and protein was markedly dose-dependently increased in the rhEPO pretreatment groups compared with the glutamate group (P<0.01).Conclusion The rhEPO pretreatment can inhibit the glu-tamate-induced apoptosis of retinal neurons by up-regulating the expression of BCL-xL .

Chinese Journal of Infectious Diseases 1999;0(01):-
Objective HCV NS3 protein plays an important role in disease caused by HCV. We investigate the gene expression of HCV NS3 in yeast for future study of the function of the protein. Methods PCR was performed to amplify the gene of HCV NS3 from the plasmid pBRTM/HCV containing the whole fragment of HCV and the gene was cloned into pGEM T vector. Thereafter, HCV NS3 gene was cut from pGEM T vector and cloned into yeast expression plasmid pGBKT7, and recombinant pGBKT7∶NS3 was transformed into yeast AH109. The yeast protein was isolated and analyzed with sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS PAGE) and Western blotting. Results HCV NS3 gene was successfully cloned into pGBKT7. The results of SDS PAGE and Western blotting assay showed that the molecular weight of the expressed product was about 22000 Da and HCV NS3 protein was existed within yeast cells.Conclusions HCV NS3 was successfully expressed in yeast expression system.

Objective To analyze the potential risk factors of sudden death at home in senile people. Methods 38 cases of cardiac arrest in a community occurring at home from 1993 to 2004 were retrospectively analyzed. The data concerning their condition of health before death, the diagnosis of the diseases confirmed, the predisposing causes of cardiac arrest, and the season and time of death were collected and analyzed. Results It was found that hypertension, CHD and diabetes were the predominant diseases in senile patients died of out-of-hospital cardiac arrest. Most of the deaths occurred in April, 73.7% of the deaths occurred during 6:00-18:00, and 81.6% cases occurred in their homes. Conclusion In senile patients, the cardiovascular diseases may be the main risk factors of out-of-hospital cardiac arrest. The patients with myocardial infarction, arrhythmia and heart failure constitute the high risk group of cardiac arrest. Usually death occurs without a portent.

Objective To observe the clinical efficacy and safety of propafenone on paroxysmal supraventricular tachycardia (PSVT).Methods 37 patients with PSVT were injected with 70 mg propafenone intravenously in 5 minutes.The unrecovered patients in 20 minutes were injected with 70 mg propafenone intravenously again,who were given 70 mg propafenone intravenously once again if not controlled in late 30 minuted.Blood pressure,heart beat,12 lead electrocardiogram were recorded before and after use of drug.Results The significant effective rate was 77.5% and effective rate was 21.6% with overall effective rate of 97.3% and effective time of 1~55 (7.1?2.8) minutes.The average accumulated dose of propafenone was 105 mg.Some side effects were observed in part of patients,including slight reduction of blood pressure,P R interval.QRS wave and Q T interval prolonged,temporary type sino atrial block,vertigo and nausea,etc whice could vanish gradually if not treated.Conclusion Propafenone by intravenous injection can quickly contro PSVT with saftey and effectiveness.

Objective To observe the specific humoral and cellular immune response in BALB/c mice injected with pS and p18S. Methods pS and p18S were constructed separately by inserting HBsAg gene fragment and the fusion gene fragment of HBsAg and mouse interleukin 18(IL 18) into the reading frame of pcDNA3.1+. Mice were injected with either plasmid intramuscularly in a total dose of 300 ?g per mouse. Every serum sample was detected for anti HBs using enzyme linked immunosorbent assay(ELISA). Furthermore, HBsAg specific cytotoxic T lymphocytes activity was measured. Results The expression of HBsAg was demonstrated by ELISA in p815 cells transfected with pS and p18S. pS can stimulate a positive antibody response. The average level was 135 mIU/ml, with the highest level of 530 mIU/ml. p18S could elicit relatively lower antibody response which was 20 mIU/ml. HBsAg specific CTL activities were 37.1% and 34% separately in pS and p18S immunized mice. It was only 13.2% when detected in pcDNA3.1+ immunization. Conclusion pS is effective to stimulate a humoral and cellular response in H 2d mice. IL 18 gene can not enhance the immune response when fused with HBsAg gene. Conversely, it seems to inhibit an immune response.
