Objective To explore the effects of dexamethasone on ovulation induction in polycystic ovary syndrome (PCOS).Methods This clinical study included 68 women with PCOS, which of them were divided into two groups: 34 in dexamethasone treating(dexamethasone combined with ovulation induction) and 34 in con-trol(ovulation induction treatment only).Subsequently, comparisons were made between pre and after drug treat-ment in two groups, the main indexes were the levels of testosterone(T), luteinizing hormone(LH), follicle stim-ulating hormone(FSH), growth rate of follicle, and body mass index(BMI).And we have also considered the o-vulation rate and pregnancy rate, and compared these indexes in dexamethasone treating group with control group.Results There were significant differences between pre and after dexamethasone treatment in the levels of T in treatment group(P < 0.01), and there were not significant differences between pre and after treatment in the lev-els of T in control group (P >0.05).LH had decreased significantly after treatment in both two groups (P <0.01), FSH had not significant differences between pre and after treatment in two groups(P >0.05).The growthrate of follicle of two groups had elevated after treatment (P < 0.01).And the ovulation rate in dexamethasone treating group was higher than that in control group(P < 0.05), but there were not significant differences between the two groups in the clinical pregnancy rates(P >0.05).There were not significant differences between pre and after treatment in the levels of BMI in both two groups (P > 0.05).Conclusions Dexamethasone can decrease the T in plasm levels.It is good for ovulation induction in PCOS.

Objective:To investigate the effects of the psychological stress on peripheral blood lymphocytes apoptosis and Bax,Bcl-2 gene expression in rats after being given different intensity of noise stress.Methods:All 24 SD rats were divided into three groups:control,high intensity of the noise stress,middle intensity of the noise stress. The apoptosis in peripheral blood lymphocytes(PBL)of rats was demonstrated with the flow cytometer to determine the percentages of apoptosis in rat PBL,and the expression changes of related Bcl-2,Bax genes were observed by us- ing immunohistochemical method.Results:1)After high intensity of the noise stress for three weeks,the apoptosis in rat PBL increased significantly compared with the control.2)After high intensity of the noise stress for three weeks, Bcl-2 expression as down-regulation in PBL,but the B ax expression remained obviously high.Conclusion:It indi- cates that apoptosis exists in the immunocytes of rats in the course of high intensity of the psychological stress and it consists with the expression of the related regulatory genes.

ObjectiveTo investigate the inhibitory effect of peroxisome proliferator-activated receptor-?(PPAR?) agonist on mesangial cell(MC) proliferation and extracellular matrix expression induced by angiotensin Ⅱ(Ang Ⅱ).MethodsThe incorporation of 3H-thymidine(3H-TdR) and cell count were used as the measurement of MC proliferation.MC cell-cycle was analyzed by flow cytometry.Mouse primary MC was treated with various concentration of Ang Ⅱ(1,10,100 nmol/L) in the presence or Absence of N-acytosistin(NAC) or rosiglitazone.Transforming growth factor-?1(TGF-?1),plasminogen activator inhibitor-1(PAI-1),and fibronectin(FN) mRNA expression were determined by real time-PCR.Reactive oxygen species(ROS) production was measured by 2,7-dichlorofluorescein diacetate(DCFDA) fluorescence.Results1.One hundred nmol/L Ang Ⅱ increased 3H-TdR incorporation and cell number by 2.14 and 2.32 fold,respectively.Ang Ⅱ-induced MC proliferation was inhibited by PPAR? agonist rosiglitazone with dose-dependent manner in mouse MC.2.One hundred nmol/L Ang Ⅱ stimulation for 24 h induced 48% MC processed to S and G2/M phase.Rosiglitazone significantly blocked Ang Ⅱ increased cell number in S and G2/M phase.3.Rosiglitazone reduced Ang Ⅱ-induced TGF-?1,PAI-1,and FN mRNA expression with dose-dependent manner.4.One hundred nmol/L Ang Ⅱ stimulation for 60 min increased ROS production by 3.85 folds.Rosiglitazone significantly inhibited Ang Ⅱ-induced ROS production.Ten ?mol/L rosiglitazone almost completely blocked Ang Ⅱ-induced ROS production.ConclusionPPAR? agonist rosiglitazone could block Ang Ⅱ-induced MC proliferation and extracellular matrix expression via inhibition of ROS production.

OBJECTIVE To prevent and control nosocomial infection(NI) among patients with hematological malignancies,and make clinical investigation.METHODS The random medical records of patients suffering from hematological malignancies in our hospital were analyzed retrospectively.RESULTS NI rate was 51.11%,in which the main infection site first was respiratory tract,next oral cavity and gastrointestinal tract.Gram-negative bacteria and fungi were the most common pathogens.CONCLUSIONS Patients with hematological malignancies are susceptible to NI,and they should be treated properly so as to prevent from infection effectively.

Objective To investigate the effect and mechanism of oxycodone on the treatment of cancerous neuropathic pain in advanced colon cancer.Methods 80 cases of advanced colon cancer in department of anorectal of Shaoxing Second Hospital of Zhejiang Province from March 2015 to March 2016 were selected and randomly divided into two groups with 40 cases in each group.The control group were treated with routine clinical treatment, and the experiment group were treated with oxycodone treatment on the basis of the control group.The levels of pain score, quality of life score, serum β-EP, calcitonin gene related peptide (CGRP) and prostaglandin E2(PGE2), clinical efficacy and adverse reaction incidence rate changes were compared between two groups before and after treatment.Results Compared with before treatment, levels of the pain score, serum β-EP, CGRP and PGE2 decreased in two groups after treatment, after treatment, the experiment group pain score (2.38 ±0.34), quality of life score (28.39 ± 3.97), serumβ-EP (228.71 ±34.92), CGRP (22.46 ±3.15), PGE2 level (2.45 ±0.35) and the incidence of adverse reactions was 17.50%, were lower than that of the control group the pain score (3.51 ±0.51), the quality of life score (33.53 ±4.76), serum β-EP (246.67 ±34.83), CGRP (30.36 ±4.25), PGE2(3.36 ±0.47) and the incidence of adverse reactions was 40.00%, the difference was statistically significant (P<0.05), the total effective rate of the experiment group was 87.50%, higher than that of the control group, the total effective rate was 60.00%, the difference was statistically significant (P<0.05).Conclusion Oxycodone can effectively reduce pain in patients with advanced colon cancer neuropathic pain score, improve the quality of life, and has high clinical efficacy and safety.

Objective: To establish a method of quantitative analysis of multi-components by single-marker (QAMS) for simultaneously determination of neoastilbin, astilbin, neoisoastilbin, isoastilbin, and engeletin in Smilax glabra, and research the tendency of content changes in different growth years by QAMS. Methods: An HPLC method was established to determine the relative correction factors of four other flavonoids by using astilbin as the internal reference standard. Then the method was used to determine the various content of five flavonoids in different growth years and validate the feasibility and accuracy by comparing the content results determined by the external standard method with QAMS. The dynamic change regularity of flavonoids in S. glabra was investigated. Results: A total of 23 samples from five batches in different growth years were simultaneously determined by external standard method and QAMS, the results deviation were all less than 1.0%. The content of five flavonoids in different growth years was different, astilbin decreased with the increase of growth years, neoastilbin, neoisoastilbin and isoastilbin had the reverse trend. Conclusion: The established QAMS method is feasible and accurate for the simultaneous determination of five flavonoids in S. glabra. Growth years have a certain impact on the content of each component.
