Objective To investigate the efficacy and safety of oral ganciclovir on cytomegalovirus viremia in patients receiving allogeneic stem cell transplantation.Methods Thirty patients who were treated with oral ganciclovir from Feb,2006 to May,2006 were studied.Intravenous ganciclovir was used 10 mg/(kg?d)for eight days before HSCT as prophylaxis of CMV infection.Cytomegalovirus was detected after HSCT once a week using polymerase chain reaction(PCR)method.If CMV was positive and CMV-DNA load was higher than 6.0?102 copies/mL and lower than 105 copies/mL,oral ganciclovir was used for the treatment(1 g,three times a day).Results CMV viremia was positive at a median time of 42 days after HSCT;median CMV-DNA load was 4.626?103 copies/mL.Good response on CMV DNA load(reduction below 6.0?102 copies/mL)was observed in 90% of oral ganciclovir and the response rate was 70.0% within 14 days.Median duration of therapy for good response was 10 days(range 2~30 days).Severe adverse effects were not observed and CMV-related disease did not occur.Conclusion Oral ganciclovir is an attractive and safe alternative for pre-emptive CMV viremia treatment in allo-HSCT recipients.

Objective To explore the effects of glucocorticoid(GC)and lipid metabolism on the pathogenesis of avascular necrosis of femoral head(ANFH).Methods Thirty-two New Zealand rabbits were randomly assigned into two groups as experiment group(n=24)and control group(n=8).Each rabbit in experiment group was given injection with 8.0mg/kg of hydrocortisone acetate for two times per week,while rabbits in control group were given normal saline in same quantity.Serum glucocorticoid(GC)concentration,total cholesterol(TC)and triglyceride(TG)were determined respectively before and 2,4,6 and 8 weeks after treatment.Rabbits were sacrificed at the 2nd,4th,6th and 8th week.The rabbits,sacrificed at the same time point,were stratified into group A(low concentration group)and group B(high concentration group)according to the GC concentration,in an attempt to observe the rate of empty bone lacuna and glucocorticoid receptor(GR)expression in the soft tissue around hips.Results The concentration of TC of experiment group began to increase since the 6th week,and that of TG since 2nd week(P0.05).In addition,the rate of bone lacuna and OD scores of GR were positively correlated at the 4th and 8th week(r=0.699 0,0.605 0,P

Objective To study the intercellular adhesion molecule-1(ICAM-1)and fat metabolism in the contribution of the incidence of steroid avascular necrosis of femoral head(ANFH).Methods 32 New Zealand rabbits were randomly divided into two groups:animals in experiment group(n=24)were given an injection of hydrocortisone acetate(8.0mg/kg)two times per week,and animals in control group(n=8)were given an injection with the same volume of normal saline.Serum total cholesterol(TC),triglyceride(TG)and ICAM-1 were quantitated before and 2,4,6,8 weeks after the treatment.2,4,6 and 8 weeks after treatment,6 animals of the experiment group and 2 of the control group were randomly chosen and sacrificed.ICAM-1 expression in soft tissue around hip was determined immunohistochemically,and pathohistological changes in femoral head were observed by light microscopy.Results Serum TC and TG levels of the animals in experimental group were significantly higher than those before treatment and those in control group in the 6th week after treatment(P

Objective To study the effect of FSH on the secretion of gastrin in the rat stomach,offering experimental evidence for reproductive endocrine hormone regulating digestive function. Methods The FSH was directly injected into the stomach of rats to observe the change of density of gastrin immunoreactive positive cells in the stomach by immunohistochemical SABC method and the gastrin level in circulating blood and gastric liquid by ELISA. Results Compared with the control group,which was injected with saline into the stomach,the density of immunoreactive positive cells was significantly increased in the stomach with FSH treatment group(P

Balantidiosis is a disease infected with Balantidium coli,and swine is the main infection source. The infection of B. coli may cause diarrhea,extra intestinal infection and co?infection with other pathogens and even intestinal necrosis. Strength?ening the manure management of both human and livestock,paying attention to personal hygiene and labor protection,and time?ly treatment of the patients are the main measures to control balantidiosis.

[Summary] It has been believed that both environmental and genetic effects play roles in the pathogenesis of type 2 diabetes. Genetic factors may influence the effect of environmental factors on risk of developing type 2 diabetes. This review focused on the latest evidence of the interaction effect of genes and the environmental factors on type 2 diabetes.

Objective To analyze the clinical distribution ,antimicbial resistance and Staphylococcal cassette chromosome mec (SCCmec) genotype characteristics of 346 methicillirrresistant Staphylococcus aureus (MRSA) clinical isolates in the hospital . Methods A total of 784 strains of Staphylococcus aureus isolated from January 2014 to January 2015 in the hospital ,MRSA identi-fication and the SCCmec genotype was conducted by PCR assay .Results 346 strains of MRSA (44 .13% ) were isolated from 784 strains of Staphylococcus aureus ,the detection rate of MRSA from sputum accounted for 43 .06% ,the secretion accounted for 48 .55% .MRSA was resistant to penicillin ,levofloxacin and erythromycin ,sensitive to vancomycin ,linezolid and teicoplanin .SCC-mec genotyping result showed that SCCmecⅡ was identified in 130 ,SCCmecⅢ in 196 ,SCCmecⅣ in 11 ,SCCmecⅤ in 9 .Conclusion SCCmecⅢ is the main genotypes of MRSA from our Hospital ,all of the MRSA strains are multi-resistant to tested antibiotics , but sensitive to vancomycin and teicoplanin .

Objective To investigate the clinical feature of fibercolonscopy in children.Methods Olympus PCF-20 and Olympus(PSD-20) were used for all examinations and treatments after bowel preparation and anesthesia.Pathological change was observed,then took pictures,and biopsy was done.Intestine polyps underwent electrocision.Results Fibercoloscopy was performed on 243 children(male 177,female 66).Age ranged from 1 to 18 years,with an average of 6.74 years.The cecum was reached in 232 of 243 cases.Abnormal findings were seen in 116(47.74%) of the cases.There were large intestine polyps in 87(35.80%) cases.All cases underwent electrocision.One hundred and fifty-seven polyps were removed with satisfactory results.Conclusion Fibercoloscopy is effective and safe in diagnosis and treatment in children with intestine diseases.

Saw palmetto fruit extract (SPE), as a herbal product, is widely used for the treatment of benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS). Recent studies show that SPE also has some therapeutic effects on chronic prostatitis, prostate cancer, sexual dysfunction, and so on. This article presents an overview on the application of SPE in the treatment of BPH, prostate cancer, and chronic prostatitis/chronic pelvic pain syndrome, with a discussion on its action mechanisms.

In the research field of quality control in Chinese medicinal materials, variation in active ingredients of medicinal plant is always the key and hot issues. With the development of high-throughput sequencing technologies and reducing cost, a large numbers of genes from medicinal plant were cloning and provide a solid foundation for further research of gene structure and its biological function, and also provides conditions for explore active ingredient variation and its quality control from the perspective of molecular pharmacognosy. This paper introduces the concept of homologous gene, gene duplication and classification. We prospect the function of duplicated genes in the role of molecular mechanism research about variation in active ingredients, aiming at providing a new way for medicinal materials quality control.
