Objective To investigate the rule of cell apoptosis after intracerebral hemorrhage (ICH) in rats, and to analyze the effect of Astragalus injection on the brain tissue water content and cell apoptosis perihematoma.Methods Experimental ICH models of rats were produced in by injection of Collagenase into right caudate nucleus using stereotaxis technique. After operation, 160 SD rats were randomly divided into 4 test groups according to different intervention time (operation meanwhile group, 6 h group,12 h group and 24 h group after operation, 32 rats in each group) and hemorrhagic control group (32 rats). The rats in test groups were treated with Astragalus injection intraperitoneally once a day. All ICH animals were killed at 4 d or 7 d after ICH. 12 rats from the above each group were used to measure brain tissue water content (dry-wet method). The effect of different initiation time point of treatment on brain tissue water content and cell apoptosis perihematoma was observed. The apoptosis perihematoma was detected by TUNEL technique.Results Compared with hemorrhagic control group, brain tissue water contents improved significantly in operation meanwhile group (4 d), 6 h group (both 4 d and 7 d) and 12 h group (4 d)(all P

Objective:To analyze the high risk behaviors of HIV/AIDS and its influencing factors in men who have sex with man(MSM)in a city,so as to provide evidence for the targeted intervention.Methods:Between July 2006 and October 2006,1000 MSM were sampled by snowball sampling and had a face to face interview by well trained investigators with informed consent.Questions on age,education background,and sex orientation were designated and 3 ml blood samples were obtained for examination of HIV and syphilis.?2 test and logistic regression analysis were used for statistical analysis.Results:The average age of the 1 000 MSM was 27.8?9.1 years old.In the past 6 months,43.6% of them had 3 or more male sex partners,53.6% had unprotected anal intercourse with men,8.0% had commercial sex with men,and 24.3% had sex with women.Elder subjects had a higher ratio of unprotected anal intercourse and male-female sex;subjects with lower educational background had more sex partners and male-female sex.Subjects working in the bathhouse had a higher ratio of commercial sex and male-female sex.Subjects with a male-female sex orientation or undetermined sex orientation had a higher ratio of commercial sex.Syphilis was detected in 93(9.3%)subjects and HIV was detected in 104(10.4%)subjects;among them 18 subjects had both syphilis and HIV.Multivariate logistic regression analysis showed that the aged(OR=3.5,95%CI 1.7-7.1),the number of male sex partners(OR=3.8,95%CI 1.9-7.6),the behavior of unprotected anal intercourse(OR=1.9,95%CI 1.0-3.5)and the infection of syphilis(OR=2.1,95%CI 1.4-3.4)were independently associated with the risk of HIV/AIDS prevalence;the knowledge of AIDS was the protective factor of HIV/AIDS prevalence(OR=0.5,95%CI 0.3-0.7).Conclusion:High risk behaviors of HIV exist in MSM population in the researched city;there is local epidemic of HIV.Interventions should be given according to age,educational background,sex orientation,etc.

Objective To survey the high risk behavior and infection of HIV/AIDS among men who have sex with men(MSM)and provide scientific evidence for HIV/AIDS prevention and control.Methods MSM were sampled by snowball sampling method and were interviewed by well trained investigators face to face under the informed consent.Their venous blood samples were collected for HIV seropositivity rate.Results A total of 1000 MSM,averagely aged(27.8?9.1)years,were interviewed,among whom 43.9% perceive AIDS knowledge.78.6% had anal intercourse with male partners,31.8% of whom always used condom in the past 6 months.8.0% participants had commercial sex with men in the past 6 months.The prevalence of HIV in the surveyed subjects was 10.4%.Conclusion Potential risk of HIV epidemic threatens local MSM who spread the risk to general population.High risk behavior is ubiquitous among MSM.It is imperative to carry out targeted interventions among MSM.

Objective To observe the intervention with electroacupuncture(EA) through regulating protein kinase(MAPK/ERK) pathway for cerebral ischemia rats.Methods SD rats were randomized into pseudo-operation group,model group and EA group.And the three groups were divided into 2-hour,one-day and 3-day subgroups according to the observation time.Focal cerebral ischemia(FCI) rat models were established by middle cerebral artery occlusion(MCAO) with heat-coagulation method.EA group received EA on Baihui(GV20) and Dazhui(GV14),qd,for 2 hours,one day and 3 days respectively.The learning and memory abilities of the rats in Y maze test and their neuroethological score were observed.Immunohistochemical method was used to observe the expression of phosphorylated extracellular signal-regulated kinase(p-ERK) after ischemia in CA1 area and CA3 area.Results In the model group,the neuroethological score was markedly increased,time for arriving the safe area in Y maze was prolonged(P

Objective To investigate the effects of total nutrient admixture (TNA) on the recovery of patients with gastric cancer after radical gastrectomy.Methods The clinical data of 50 patients with gastric cancer who were admitted to the Affiliated Hospital of Luzhou Medical College between March 2013 and March 2014 were retrospectively analyzed.Among 50 patients receiving radical gastrectomy,26 patients receiving TNA were allocated to the experimental group and 24 patients receiving conventional fluid infusion were allocated to the control group.Patients in the experimental group received the nutritional support therapy using TNA at preoperative day 5 and at postoperative days 1-5,and patients in the control group received the postoperative intravenous rehydration including water,glucose,electrolyte,vitamins and micro elements.The nutritional indexes [albumin (Alb),prealbumin,transferrin and hemoglobin (Hb)],time to anal exsufflation,incidence of complications (wound infection,anastomotic leakage,blooding and intestinal obstruction) and duration of hospital stay were observed before nutritional support therapy and at postoperative day 8.The count data were analyzed using the chi-square test.The chi-square value of correction for continuity was used when 1 ≤ minimum theoretical frequency ≤ 5.The measurement data with normal distribution were presented as (x) ±s and analyzed using the t test or repeated measures ANOVA.The ordinal data were analyzed by the analysis of variance.Results The Alb,prealbumin,transferrin and Hb in the experimental group were (38.6 ± 2.0) g/L,(281 ± 33) mg/L,(2.5 ± 0.9) g/L and (111 ± 20) g/L before nutritional support therapy and (38.2 ± 1.9) g/L,(277 ± 16) mg/L,(2.3 ± 1.1) g/L and (112 ± 37) g/L at postoperative day 8,respectivley.The Alb,prealbumin,transferrin and Hb in the control group were (38.3 ±2.4) g/L,(287 ± 34) mg/L,(2.4 ± 1.1) g/L and (107 ± 21) g/L before nutritional support therapy and (30.3 ±2.3) g/L,(190 ± 41) mg/L,(1.6 ± 0.3) g/L and (93 ± 22) g/L at postoperative day 8,respectivley.There were significant differences in the nutritional indexes at postoperative day 8 between the 2 groups (F =174.042,95.637,9.529,4.919,P ＜ 0.05).The time to anal exsufflation in the experimental group were (52 ± 11) hours,which was significantly different from (70 ± 12) hours in the control group (t =-5.176,P ＜ 0.05).The incidence of complications was 15.4％ (4/26) in the experimental group,which was significantly different from 58.3％ (14/24) in the control group (x2=6.460,P ＜0.05).Patients with complications in the 2 groups were cured by anti-infective or symptomatic treatment.The duration of hospital stay was (9 ± 3) days in the experimental group and (12 ± 4) days in the control group,with a significant difference between the 2 groups (t =-2.912,P ＜ 0.05).Conclusion TNA can improve the nutritional status of patients after radical gastrectomy in a short time.It could help patients to get through the perioperative period smoothly,and enhance the postoperative recovery.

Objective:To optimize the determination technology for the total amino acids in Runing pills. Methods:The process was optimized by L9 (34 ) orthogonal design using the hydrolysis temperature, hydrolysis time and hydrochloric acid concentration as the evaluation factors,and the content and yield of total amino acids as the evaluation indices. Results: The optimal determination condi-tions were as follows:the hydrolysis temperature was 110℃, the hydrolysis time was 22 h and the hydrochloric acid concentration was 6 mol·L-1 . Conclusion:The optimal determination technology can be applied in the total amino acids from Runing pills,which pro-vides the basis for the further research of Runing pills.
