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.

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 .

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.

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.

The nonstructural protein 5A (NS5A) of the hepatitis C virus (HCV) has been shown to interact with a variety of cellular proteins and implicated in the regulation of cell growth, interferon resistance, and other cellular signaling pathways. Using the yeast-two hybrid method, we have isolated a clone that encodes a novel NS5A--associated binding protein: NS5ABP37. Reverse transcription polymerase chain reaction (RT-PCR) method was employed to amplify the full fragment,and the plasmid pGADT7-NS5ABP37 with the Saccharomyces cerevisiae vector pGADT7 was constructed. To prove the interaction, yeast cell Y187 transformed with pGADT7-NS5ABP37 was mated with yeast cell AH109 containing pGBKT7-NS5A to verify the interaction between the novel protein coded by the new gene NS5ABP37 and NS5A.

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 explore the clinical significance of APACHE Ⅱ score on risk stratification in patients with acute myocardial infarction.Methods One hundred and forty-two patients with acute myocardial infarction were included in the study who were admitted to hospital consecutively from Jan.2011 to Dec.2012.High risk group and low risk group were divided by the APACHE Ⅱ score.Some clinical variables at the first 24 h after admitted to hospital and occurring during the following 1 year were recorded Results The age in high risk group was 78.9 ±8.1,significantly higher than that in low risk group (65.8 ± 10.2;t =6.835,P ＜ 0.001).The cases with Killip Ⅲ and Ⅳ in high risk group were 10(29.4％) and 2(1.8％),lower than in low risk group (6 (1.8％) and 0 (0％) ; x2 =21.950,15.777 ; P ＜ 0.005).The level of creatine kinase-MB (CK-MB) and cardiac troponin Ⅰ in high risk group were (147.7 ±21.5) U/L and (105.5 ± 17.6) U/L,higher than in low risk group((105.5 ± 17.6) U/L,(42.9 ± 6.3) U/L; t =11.541,5.785 ; P ＜ 0.001).The incidence of severe cardiac events(malignant arrhythmia,heart failure,non fatal myocardial infarction and death from any cause in high risk group were 58.8％ (20/34),47.0％ (16/34),17.6％ (6/34) and 17.6％ (6/34),higher than in low risk group (29.6％ (32/108),3.7％ (4/108),6.4％ (7/108) and 6.4％ (7/108) ; x2 =8.274,36.665,3.876 and 3.876 ; P ＜ 0.05).Conclusion APACHE Ⅱ score is likely to be a simple and practical tool for risk stratification in patients with acute myocardial infarction.
