Objective To evaluate the effect of Jianpi Bushen Formula(Formula for Invigorating Spleen and Nourishing Kidney) combined with moxibustion on quality of life(QOL) and maturation degree of vaginal exfoliate cells(MDVEC) in premature ovarian failure(POF) patients.Methods Totally 55 POF patients were randomized into treatment group(33 cases,treated by Jianpi Bushen Formula with moxibustion) and control group(22 cases,treated by Premarine).Menopause-specified quality of life(MENQOL) was adopted to evaluate QOL of the patients.Maturation index(MI) and maturation value(MV) were applied to evaluate MDVEC.Results The scores of MENQOL of both groups were improved and the effect of the treatment group(except sexual life dimension) was superior to that of the control group(P

? Choroidal neovascularization is the primary pathogenesis of neovascularage - related macular degeneration ( nAMD ) , and the role of vascular endothelial growth factor ( VEGF ) in neovascularization has been widely recognized. Currently, drugs target different targets of VEGF have been widely used in the treatment of nAMD. As a subtype of VEGF, placental growth factor ( PlGF) has synergistic effects with VEGF-A on promoting angiogenesis, stimulating the migration of endothelial cell proliferation and mediating immune inflammatory response. There is no expression of PlGF in mature blood vessels so PlGF hashigh specificity. ln this paper, the role of PlGF in the pathogenesis and treatment of nAMD is reviewed.

Objective To investigate the effects of RNA interference (RNAi) targeting angiotensinconverting enzyme (ACE) on blood glucose,insulin resistance,as well as oxidative stress in type 2 diabetic rats.Methods Type 2 diabetic rats were divided into diabetes control group (caudal intravenation with control adenovirus named Ad5),gene treatment group (caudal intravenation with recombinant adenoviral vectors named Ad5-ACE-shRNA,expressing ACE gene-specific shRNA),and enalapril group (intragastric administration with enalapril every day).At the same time,the normal blood glucose control group was set up.All rats were injected two times during the experiment period.Blood glucose was measured before and after the intervention.At the third day of the experiment,expressions of ACE mRNA and protein in pancreas were evaluated by RT-PCR and Western blot,and serum concentrations of ACE and Ang Ⅱ were measured by ELISA.By the end of the experiment,insulin sensitivity index was calculated and expressions of glucose transporter 4 (GLUT4) protein of epididymal adipose tissue and NAD (P) H (p22phox) protein of pancreas were measured.Results Blood glucose levels in the gene treatment group [(17.8 ±1.1) mmol/L] and the enalapril group [(17.9 ± 1.2) mmol/L] were lower than that in the diabetes control group [(24.9 ± 1.3) mmol/L] when the experiment was finished.ACE mRNA and protein expressions in pancreas of the gene treatment group were significantly decreased compared with the diabetes control group (P ＜ 0.05).Serum concentrations of ACE and Ang Ⅱ in the gene treatment group were (16.37 ± 3.01) ng/ml and (18.24 ± 3.69)pg/ml,significantly lower than those of the diabetes control group [(46.67 ± 3.92) ng/ml and (44.93 ± 4.12) pg/ml respectively,both P＜0.05].Insulin sensitivity indexes of the gene treatment group and the enalapril group were (-5.14 ± 0.41) and (-5.17 ± 0.38),being all significantly higher than that of the diabetes control group (-6.18 ±0.46,both P＜0.05).Expressions of GLUT4 protein in epididymal adipose tissue were higher and expressions of p22phox protein in pancreas were lower in the gene treatment group and the enalapril group than those of the diabetes control group (both P＜0.05).Conclusions RNAi targeting ACE gene may delay the progress of hyperglycaemia and improve the situation of insulin resistance and oxidative stress.The RNAi technology may be used as a new strategy of gene therapy for diabetes mellitus.

Objective To verify the detection ability of experimental animal quality detection laboratories in China for Staphylococcus aureus.Methods The testing samples for Staphylococcus aureus detection were prepared by bacterial culture, homogeneity test and stability test, according to the study plan approved by CNAS.Then the samples and operation instruction were sent to the participant laboratories.The detection reports from these laboratories should be submitted before the deadline expires, and the collected data were summarized and analyzed.Results There were 28 laboratories which joined to this test plan.Among them 22 laboratories ( 78.57%) achieved satisfactory test results, and six laboratories (21.43%) had unsatisfactory test results.27 Laboratories used the national standard detection assay, while only one labo-ratory used PCR assay.Conclusions Most of experimental animal quality testing laboratories in China have sufficient pro-ficiency in detection of Staphylococcus aureus.The obtained information are very helpful for the laboratory ability verification testing in future.

The gene approach to the pathogenesis of male infertility may bring about some strategies for the diagnosis and manage of the condition. Gene knockout technology is the mainstream method currently used in the study of gene function. Screening and identification of testis-specific genes and insights into their features and functions in spermatogenesis are significant for a further understanding of testicular functions and searching for new therapeutic targets for male reproductive disorders. This review focuses on the application of gene knockout technology in the study of spermatogenesis-associated genes.

OBJECTIVETo explore the clinical outcomes of percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) in treating osteoporotic vertebral compression fracture (OVCF).

METHODSFrom January 2007 to February 2010, the data of 40 patients with osteoporotic vertebral compression fracture underwent treatment were retrospectively analyzed. Of them,20 patients were treated with PVP (PVP group), there were 8 males and 12 females with an average age of (66.37 +/- 2.34) years old (54 to 81); 20 patients were treated with PKP (PKP group), there were 11 males and 9 females with an average of (65.12 +/- 3.21) years old (56 to 79). Postoperative at 1 week, 12 weeks, 1 year, pain and daily life function were respectively assessed by visual analogue scale (VAS) and Barthel index (BI); and anterior height of responsibility vertebra, Cobb angle were measured by X-rays.

RESULTSIn PVP group, 1 case complicated with bone cement leakage without clinical symptoms and no operation to treat. No postoperative infection and deep vein thrombosis were found between two groups. All patients were followed up more than 1 year, pain and daily life function has obviously improved than preoperative (P < 0.01); and there was no significant difference on 1 week, 12 weeks, 1 year after operation (P > 0.05); there was no significant difference between two groups (P > 0.05). In PVP group, there was no significant difference in anterior height of responsibility vertebra, Cobb angle before and after operation;and in PKP group, postoperative data has obviously improved than preoperative (P < 0.01), but there was no significant difference postoperative at 1 week, 12 weeks, 1 year (P > 0.05); there was no significant difference between two groups at 1 week, 12 weeks, 1 year after operation.

CONCLUSIONBoth the methods can obviously relieve pain and completely or partly recover daily life function in treating OVCF. But PKP has advantages of recovery of anterior height of responsibility vertebra and correction of Cobb angle, especially for serious compression.

Objective To investigate the protective effects of Wnt-7a protein on renal interstitial fibrosis in mice of unilateral ureteral obstruction (UUO)model.Methods Eighteen male C57BL/6 mice were randomly divided into 3 groups:sham-operation group,the UUO model group and Wnt-7a treatment group.The body weight of mice was measured everyday.All the mice were sacrificed at thc seventh day after the operation.The left kidney was taken for histology evaluation and molecular biology assay.Masson's stain was performed as a main indicator of interstitial fibrosis.The expression of vimentin,α-smooth muscle actin,and E-adherin in renal tissue was detected by immunohistochemistry staining and the expression of α-smooth muscle actin and E-cadhe(nn) in renal tissue was detected by Western blotting.Results Compared with sham-operation group,body weight of the (,)odel group was significantly lower (P＜0.05),and the relative area of interstitial fibrosis was significantly larger (P＜0.05).Furthermore,the expression of vimentin and α-SMA was significantly up-regulated (P＜0.05),and the expression of E-cadherin was significantly down-regulated (P＜0.05).Compared with model group,all the above-mentioned abnormalities were restored to some extent and showed significant differences (P＜0.05) in Wnt-7a treatment group.Conclusion Wnt-7a protein can decrease the interstitial fibrosis by inhibiting epithelial to mesenchymal transition in UUO mice.

Now organophosphorus pesticides (OPs) bioremediation mainly means microbial bioremediation. However, phytoremediation has an advantage over microbial bioremediation because phytoremediation is safer and costs less than microbial bioremediation. Nevertheless, phytoremediation has limitations yet such as plants need better growth conditions and the efficiency of phytoremediation is lower. All these have confined the application of phytoremediation. Progresses of microbial bioremediation and phytoremediation of OPs were reviewed and OPs degrading enzymes and their organism sources, which are known by now, were summarized. Moreover, there are five important ways to enhance the efficiency of phytoremediation of OPs. They are culling plants, studying the action between soil and OPs, studying the genes that can resist or get rid of OPs, setting up the combined system of microbial bioremediation and phytoremediation and using degrading enzymes secreted selectively by roots.
