Human cytomegalovirus (HCMV) has a higher prevalence in the population, and most normal individuals after primary infection can establish latent infections. Recent reports have suggested that cytomegalovirus infection associated with lipid metabolism, and play an important role in the pathogenesis of many diseases, such as hepatitis, atherosclerosis, isolated syndrome, metabolic syndrome, etc. This article summarized the relationship between cytomegalovirus infection and lipid metabolism, as well as its role in a variety of diseases progression.

Objective To investigate the effect of silodosin,a selective alpha1 a-adrenoceptor antagonist on a rat model of testosterone-induced benign prostatic hyperplasia (BPH) and its mechanisms.Methods The rats were divided into three groups:control,testosterone-induced BPH,and silodosin +BPH groups.BPH was induced by subcutaneous injection of testosterone [20 mg/(kg · d)] for 4 weeks.Meanwhile silodosin + BPH groups rats were administered silodosin 4 weeks [100 μg/(kg · d)].After 4 weeks,all animals were sacrificed to examine the blood biochemical profiles,prostate volume,weight,histopathological changes,and epidermal growth factor receptor (EGFR) and B-cell chronic lymphocytic leukemia (CLL)/lymphoma 2 (BCL-2) protein expressions.Results Each group showed an increase compared to their initial body weight;however,differences in weight change between groups were not significant (P ＞ 0.05).The BPH group displayed lower glucose levels than the control group.The serum levels of glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) were not significantly different among groups (P ＞ 0.05).The group treated with silodosin showed significantly lesser prostate size and weight than the testosterone-induced BPH group [volume:(0.93 ± 0.14) cm3 vs (1.75 ± 0.15)cm3,P ＜0.01;weight:(0.97 ±0.06)g vs (1.30±0.05)g,P ＜0.01].In addition,silodosin decreased the expressions of EGFR and BCL-2 in prostate tissues (P ＜ 0.05).Conclusions These results suggest that silodosin suppress the development of BPH by inhibiting the expressions of EGFR and BCL-2.

Currently,the most effective treatment for acute ischemic stroke is administration of tissuetype plasminogen activator for intravenous or intra-arterial thrombolysis within 3 to 6 hours after symptoms onset.However,the narrow therapeutic time window and the risk of intracranial hemorrhage have limited its clinical application.Angiogcncsis refers to the process of the formation of new functional blood vessels with the manner of germination from the already existing network of blood vessels.An increasing number of studies have shown that histone deacetylases involve in the regulation of angiogenesis.It may become a potential stroke treatment strategy.This article reviews the role of histone deacetylases in the regulation of angiogenesis.

ObjectiveTo summarize the clinical features of adult patients with abdominal type Henoch Scholein Purpura(HSP) to improve the early diagnosis and therapeutic outcome of HSP.Methods The clinical features of 31 adult patients with abdominal type HSP from the Hematology department of Handan First Hospital between March 2007 to June 2010 were retrospectively reviewed and compared with that of 30 adult patients with non-abdominal type HSP.Results All the 31 patients had abdominal pain.Of those patients,48.4％ had periumbilical colicky pain, 38.7％ had whole abdominal pain and 12.9％ had lower abdominal pain.The other clinical manifestations included nausea/vomiting(19.4％),positive feces occult blood test(45.1％) .EGD and Colonoscopy of 13 patients showed mucosal congestion, red macda, erosion and ulceration mainly in the descending duodenum, distal ileum and rectosigmoid.There was no difference in age, gender, allergic history and predisposing infection between those with abdominal pain and without.The patients with abdominal pain had more cases of mixed-type HSP than those without and the difference was significant (P ＜ 0.01) .Conclusion Patients with abdominal-type of HSP are mainly young adults.So we must be more alert to abdominal-type of HSP when facing young patients with abdominal emergency.Abdominal-pain-manifesting HSP patients are mostly mixed-type cases.Gastrointestinal endoscopy is specific and might provide valuable clues for early diagnosis.

We have observed the effects of five alga polysaccharides on rabbit's blood platelets aggregation. We found that the polysaccharides could inhibit aggregation of blood platelets in vitro. The strongest effect was observed in the polysaccharides from the following,in decreasing order of strength: Scytosiphon lomentarius, Codium fragile,Laminaria japonica and Ulvalactuca. The same effect was not observed in polysaccharides from Cladophra. We also found a positive correlation between the effects of anti-aggregation and the ratio of vitriol radicles in these five polysaccharides.

0.05. Statistics from 7 papers revealed the mean survival rate of TCM group was 335. 4 days, that of chemotherapeutic group 231. 8, test of significance P = 0. 1489. MA results showed that the features of TCM treatment on NSCL were: high stability, low effectiveness, however, with certain dominance.

Objective To study the different pathogenesis between non-erosive gastroesophageal reflux disease(NERD) and reflux esophagitis(RE).Methods 57 patients with regurgitation or heartburn from 1996 to 2004 were assessed in this study.Patients with esophageal mucosal break by endoscopy were regarded as the RE group,others as the NERD group.The clinical feature and whether complicating with H.pylori infection in both groups were reviewed and all patients underwent esophageal manometry and 24 hours esophageal/gastric pH monitoring.Results No differences of age?sex?smoking?drinking and Hp infection were found between the two groups.The incidence of the atypical reflux symptom (chest pain) in the NERD group was higher than in the RE group.There was pathologic acid reflux in both groups,but the two groups did not differ at reflux degree.Esophageal body peristaltic amplitude of the NERD group was higher than that of the RE group.Average gastric pH of the NERD group in supine was lower compared with the RE group.Conclusion In the NERD patients,the incidence of the atypical reflux symptom is more prevalent.It is the esophageal acid clearance not the reflux degree that plays an important role in the different pathogenesis between NERD and RE.

In this study,we have observed the effects of extract from mussel ( Mytilus edulis Linnaeus ) on experimental hyperlipidemia in rats.The results showed that the extract from mussel could reduce the levels of total cholesterol and triglyceride in blood serum of the experimental hyperlipidemic rats.

Objective To distinguish primary CMV infection from reactivation or reinfection. Methods A urea denaturation test was included in the washstep of the standard IgG ELISA in 12 patients of age＜12 whose serum CMV-IgG were positive, avidity indexes of CMV-IgG were measured. Results Among children aged 1～12 years, the varieties of avidity indexes of CMV-IgG in A group(IgM negative and IgG positive) and B group(IgM positive and IgG positive) had the same trend. There was only one case in B group whose avidity index was under 30%, the other were all above 30%, and most were above 50%. But among 40 children aged 1～12 months,the avidity indexes were under 30% in 21 cases,8 cases were 30～50% ,and 11 cases were above 50%. The antibody avidity in 1～6 months children was influenced by their mothers lgG,80% (12/15) of 7 ～12 months children had low-avidity antibodies. Conclusion CMV infection mostly occurred among 1～12 months children. Urea denaturation test was an efficient method to distinguish primary CMV infection from reactivation or reinfection.

Piplartine is an alkaloids/amide component of Piper species,having diverse pharmacological and biological activities.Recent studies have indicated that piplartine has inhibitory effects on several kinds of tumors and is a kind of potential antitumor drugs.It can inhibit the proliferation of tumor cells,cause cell cycle arrest and induce apoptosis.More investigations suggest that targeting the reactive oxygen species(ROS) stressresponse pathway is closely related to its antitumor activity.
