Background At present,researches about retinitis and acquired immunodeficiency syndrome (AIDS) mainly focus on observation and analysis of the cytomegalovirus (CMV)-induced ocular complication.To screen the effective drugs is very important for the treatment of AIDS-related CMV-induced retinitis.Objective This study was to describe the clinical features,diagnosis and treatment outcome of CMV-induced retinitis with BAY 38-4766 and evaluate the relationship between CMV retinitis and AIDS.Methods This was a case observational study.A total of 154 eyes of 84 patients with CMV retinitis and AIDS were enrolled in this study.Before the definitive diagnosis of CMV retinitis,the AIDS course of these patients were 4-26 months.In the initial examination,the visual acuity ranged from finger counting to 0.4,and the number of CD4+ T-lymphocyte was 0-30 cells/μl.The survival time in the patients ranged from 3 weeks to 18 months.BAY 38-4766 was used in 117 eyes of 62 patients,and 102 eyes of 53 patients showed the srinked of retinal lesion and improvement of vision (0.1-0.7).BAY 38-4766 was used to treat the CMV retinitis in 117 eyes of 62 patients with the initial intravenous dose of 5 mg/kg,twice per day for consecutive 2 weeks and followed by oral dose 1 gram per day.The follow-up duration was 2 weeks to 18 months.The fundus feature,visual acuity and CD4+ T-lymphocyte counts were analyzed.This study proposal was approved by Ethic Committee of the 474th Hospital of PLA,and written informed consent was obtained from each patient prior to entering this study.Results The numbers of CD4+T-lymphocytes increased to 12-402 eells/μl after administration of BAY 38-4766.The CMV retinitis aggravated and the vision decreased in the untreated 22 patients with the CD4+T-lymphocytes 0-30 cells/μl.Conclusions CMV retinitis is the most common intraocular complication in patients with AIDS.Diagnosis of CMV retinitis is based on the characteristics of necrotizing retinitis,which is typically associated with retinal hemorrhage and vasculitis.BAY 38-4766 is an effective drug for the treatment of CMV retinitis.

Objective To study the influence of sex on the prognosis in acute ST elevated myocardial in- farction(STEMI)patients after primary percutaneous coronary intervention(PCI).Methods :The risk factors, coronary angiography and prognosis in 478 males and 101 females with STEMl were compared.Results:Mortality of STEMI was significantly different in different age groups(P<0.01).The attack of the STEMI in women was 10 vears later than that of men(P<0.01),especially in those women whose age was over 71 years oId.The complica- tion ratio of hypertension and type 2 mellitus diabetes was higher in female patients than that in male(P<0.01). More multi-vessel lesions were found in female patients than those in male(P<0.01).The incidence of in-hospital mortality,pseudoaneurysm,haematoma Was significantly higher in females than in males(P<0.05.P<0.01).Con- clusions The in-hospital mortalitv and puncture complications in STEMI female patients treated with primary PCI are higher than male patients.

Objective To investigate the effects of morroniside on activation of caspase-3 in rats with focal cerebral ischemia/reperfusion. MethodsThe model was induced with occlusion of middle cerebral artery with suture embolus, ischemia for 30 min, and reperfusion for 72 h in rats. Vitamin E used for the positive control. The activity of caspase-3 was detected with spectrophotometry. ResultsCompared with sham group, the caspase-3 activity increased obviously in model rat. Compared with model group, Morroniside (30 mg/kg,90 mg/kg,270 mg/kg) decreased the activation of caspase-3 remarkably, which was dose-dependent (P<0.05). ConclusionMorroniside may reduce apoptosis by decreasing the activation of caspase-3 in rats.

ObjectiveTo investigate the effects of morroniside on IL-1β in rat cortex with focal cerebral ischemia/reperfusion.MethodsThe animal model was induced by occlusion of middle cerebral artery with suture embolus, ischemia for 30 min, and reperfusion for 72 h in rats. The content of IL-1β was detected with enzyme linked immunosorbent assay(ELISA).ResultsCompared with sham group, the content of IL-1β increased obviously in model rat. Compared with model group, morroniside(30 mg/kg, 90 mg/kg, 270 mg/kg) and colchicine (0.06 mg/kg) decreased the content of IL-1β significantly (P<0.001).ConclusionMorroniside may protect the cortex from inflammatory factor IL-1β.

Cerebral ischemia-reperfusion results in damage on neuron, leading to genes and proteins related to apoptosis activation. At the same time, generous cytokines released after cerebral ischemia-reperfusion can induce the apoptosis of the neuron. Many current studies have showed that the major damage mechanisms on apoptosis of the neuron are mitochondrion impairment, calcium overload, increased levels of oxygen radicals and so on. The advance research on the mechanism contributes to explore new neuroprotective drugs, and further identify the target and therapeutic effect of drug treatment.

OBJECTIVE: To analyze the characteristics in the incarcerated inmate's death, investigate the main cause of death of the incarcerated inmate and provide some information for forensic investigation. METHODS: The cases from the forensic medical center of Shanxi Medical University from 2005 to 2013 were selected. The statistical analysis was performed by using the incarcerated inmate's gender, age, cause of death, manner of death, and disease as the markers. RESULTS: There were 100 men, 5 women in the 105 incarcerated inmates; the age range was from 16 to 65 years; Inmates were mostly died of natural diseases, mainly in the respiratory and cardiovascular diseases; the main unnatural death was suicide with a rate of 54.5%. CONCLUSION At present, most incarcerated inmate's death are due to natural diseases. The prison should improve incarcerated inmate's lives, work and health care conditions, and strengthen supervision of law enforcement.

In this study, the general bacterial probe and specific cellulolytic bacterial probes were used to quantify the bacteria in rumen. The total RNA were extracted and then hybridized with general bacterial probe after a dilution of concentration. The result showed that there was a high correlation between the hybridization signal and the dilution of total bacterial RNA. Based on the result above, the quantities of three cellulolytic bacteria in rumen sample were detected. The comparative RNA percentage of three cellulolytic bacteria to total bacterial RNA were similar to the previous reports. It can be concluded that the quantification of bacteria in rumen could be conducted by this approach, and which could be used in future research.

OBJECTIVE: To investigate the potential risk factors and management of excessive epistaxis after endoscopic endonasal surgery (EES). METHOD: Six hundred and forty-one patients who underwent EES in our hospital from December 2011 to December 2012 were reviewed retrospectively. Factors which potentially affect the incidence of excessive epistaxis after EES were analyzed with univariate and multivariate logistic regression model. RESULT: The incidence rate of excessive epistaxis after EES was 8.4% in our study. Multivariate logistic regression analysis revealed that history of previous EES, along with other four factors, correlated significantly with the occurrence of excessive epistaxis after EES. CONCLUSIONS Previous EES, along with other three factors, may increase the chance of excessive epistaxis after EES, while pre-operative corticosteroid therapy may reduce the risk to some extent.

Objective To investigate the effect of 3-bromopyruvate (3-BrPA) on transplanted rectal tumors in experimental rabbit models. Methods A total of 60 New Zealand white rabbits with transplanted rectal tumor were randomly and equally divided into low-dose (0.5 mmol/L), medium-dose (1.0 mmol/L), high-dose (2.0 mmol/L) treatment groups and saline control group with 15 rabbits in each group. Arterial perfusion of 10 ml 3-BrPA with concentration of 0.5 mmol/L, 1.0 mmol/L and 2.0 mmol/L via caudal mesenteric artery was respectively employed for the rabbits of the corresponding treatment group; the control group was perfused with equal amounts of saline. Four days later, rectal tumors were removed by vivisection. The necrosis degree of tumor cells was determined by microscopic examination, and the necrosis rate was calculated. The effect of different 3-BrPA concentrations on the rectal tumor was evaluated. Results The rectal tumor transplantation and transcatheter 3-BrPA or saline perfusion was successfully completed in all 60 experimental rabbits. Microscopically, tumor cells showed different degrees of damage in experimental rabbits. In low-dose (0.5 mmol/L) treatment group, gradeⅠnecrosis was observed in 3 rabbits, gradeⅡin 11 rabbits, and gradeⅢin one rabbit;the effective rate was 6.7%. In medium-dose (1.0 mmol/L) treatment group, gradeⅡnecrosis was seen in 2 rabbits, grade Ⅲ in 10 rabbits, and grade Ⅳ in 3 rabbits; the effective rate was 86.6%. In high-dose (2.0 mmol/L) treatment group, gradeⅢnecrosis was detected in 2 rabbits and gradeⅣin 13 rabbits;the effective rate was 100.0%. In the saline control group, grade I necrosis was observed in 15 rabbits. Statistically significant differences in tumor necrosis rate and effective rate existed between medium-dose (1.0 mmol/L) treatment group and high-dose (2.0 mmol/L) treatment group (P<0.05). Statistically significant differences in tumor necrosis rate also existed between each other among the four groups with necrosis of gradeⅠto gradeⅣ(P<0.05). 3-BrPA had obvious therapeutic effect, while it showed no damage to the normal intestinal tissue. Conclusion For the treatment of transplanted rectal tumor in rabbit models, arterial infusion of 3-BrPA has certain therapeutic effect. In the high-dose group, the necrosis rate and effective rate are the highest, and the therapeutic results are the most significant.
