Objective To evaluate the therapeutic effects of metformin hydrochloride and rosiglitazone maleate tablets on insulin resistance and androgen concentration in obese and nonobese women with polycystic ovarian syndrome (PCOS).Methods Seventy women with PCOS were enrolled into this study according to the diagnostic criteria of Rotterdam conference (2003).The women with PCOS were divided into the over weight/obese group (body mass index ≥ 25 kg/m2,n =34) and the nonobese group (body mass index＜25 kg/m2,n =36).All women with PCOS took metformin hydrochloride and rosiglitazone maleate tablets twice daily for 3 months.The following indexes were measured before and after the treatment:height,weight,waist circumference,hip circumference,fasting plasma glucose,fasting plasma insulin,luteinizing hormone (LH),follicle stimulating hormone (FSH),total testosterone,free testosterone,follicular number and ovarian area,body mass index,waist to hip ratio,and homeostasis model assessment for insulin resistance (HOMA-IR) were calculated.Results (1) Compared with the nonobese group,dramatic increases in HOMA-IR and follicle number were observed in over weight/obese group(P＜0.05),while LH,LH/FSH,total testosterone,free testosterone showed no significant difference between two groups.(2) After the treatment with metformin hydrochloride and rosiglitazone maleate tablets,weight,body mass index,fasting plasma glucose,fasting plasma insulin,HOMA-IR significantly decreased in two groups (P ＜ 0.05).There were also significant declines of LH,LH/FSH,free testosterone,ovarian area,follicular number,especially in the over weight/ obese women with PCOS (P＜0.05),while total testosterone and FSH did not change significantly.(3) The incidence of gastrointestinal adverse reactions in nonobese and over weight/obese group was 9.3％ and 6.3％ respectively,and no liver toxicity,edema,hypoglycemia and other adverse reactions was observed during treatment.Conclusion Compared with the nonobese group,there were severer insulin resistance and more marked polycystic change of ovary in over weight/obese women with PCOS,while total testosterone and free testosterone showed no significant difference between two gruops.Metformin hydrochloride and rosiglitazone maleate tablets can ameliorate insulin resistance and polycystic ovary,and also reduce body mass index and free testosterone in women with PCOS particularly in the over weight/obese individuals.

Objective:To investigate the effect of chronic ethanol consumption on sensory information transmission in the cerebellar molecular layer and reveal the mechanism of chronic alcoholism on sensory information transmission and integration in the cerebellar cortex.Methods:Fifty healthy male ICR mice aged 6-8 weeks were randomly divided into saline group(control group)and ethanol consumption group(alcohol group) according to the random number table, with 25 mice in each group.The mice in alcohol group were injected intraperitoneally with 20% ethanol daily, while the mice in control group were injected with the same dose of normal saline. All mice were injected intraperitoneally once a day for 28 days.Through electrophysiological technology, patch-clamp amplifier and data acquisition software were used to record the changes in cerebellar molecular layer field potential of mice in the alcohol group and control group induced by sensory stimulation.Clampfit 10.3 software was used to record and analyze the electrophysiological data. SPSS 22.0 software was used for statistical analysis. Paired t-test and one-way ANOVA were used to analyze the differences before and after treatment. Results:After giving the stimulation of wind blowing, the amplitude of P1 in alcohol group was significantly higher than that in control group ((121.31±3.5)%, (97.2±2.7)%; t=26.08, P<0.05), and the area under the P1 curve (AUC) of the alcohol group was significantly lower than that of the control group ((127.1±4.2)%, (102.2±3.5)%; t=22.95, P<0.05). There was no significant difference in N1 amplitude between the two groups (P>0.05). When L-NNA, an inhibitor of nitric oxide synthase, was perfused into the brain surface of mice, the amplitude of P1 in alcohol group was significantly lower than that before administration ((76.2±4.8)%, (103.5±3.6)%; t=22.60, P<0.05), but there was no difference of the amplitude of P1 before administration and after elution ((101.5±4.6)%) ( t=1.70, P>0.05). After the L-NNA was perfused, the AUC of P1 was significantly lower than that before administration((72.4±5.6)%, (102.7±2.66)% ( t=24. 58, P<0.05), and there was no significant difference between before administration and after elution( (100.6±3.5)%, t=1.81, P>0.05). When L-NNA was perfused into the brain surface of mice, the amplitude of P1 in control group was (104.3±1.6)% and it had no differences compared with before administration(102.2±5.6)%, t=1.84, P>0.05) and after elution(102.5±4.5)%, t=1.92, P>0.05). And the AUC of P1 in control group after perfused L-NNA had no differences compared with before administration(103.5±2.6)%, (102.5±4.6)%) and after elution((101.9±3.7)%, t=0.99, 1.81, both P>0.05). When the mouse brain surface was perfused with NO donor SNAP, the amplitude of P1 in the control group was significantly higher than that before administration( (128.2±3.4)%, (103.5±2.6)%; t=28.89, P<0. 05) and there was no difference between before administration and after elution( (105.4±4.2)% , t=1.93, P>0.05). The AUC of P1((125.4±4.4)%) was higher than before administration((104.3±4.6)% , t=16.60, P<0.05) and there was no difference between before administration and after elution(103.5±4.2)%, t=0.65, P>0.05). Conclusion:Chronic ethanol consumption significantly enhances the inhibitory response, and the enhancement of inhibitory components stems from the activation of the NO signaling pathway.

Objective To explore the effect of continued self-efficacy health education after discharge on patients with benign prostatic hyperplasia. Methods Toally 100 patients with benign prostatic hyperplasia during January to December 2015 were equally assigned to control group and observation group by random digit table:the former was treated with discharge instructions and the latter with discharge instruction plus self-efficacy health education. The two groups were compared before intervention and 6 weeks after intervention in terms of health behavior and self-management ability. Results Before intervention, there were no significant differences between the groups in health behavior and total score of self-management ability as well as the scores on its dimensions (P>0.05). After intervention, however, the total scores on health behavior and self-efficacy ability as well as the scores on the dimensions in the observation group were significantly higher than those of the control group (all P<0.01). Conclusion Post-discharge continued self-efficacy health education can be effective in improving their health behavior and self-management ability, which can promote their recovery.

Raw264.7 cells were incubated with receptor activator of NF-kappa B ligand (RANKL) and α-melanocyte stimulating hormone(α-MSH) for6 d.The amount of osteoclast cells were counted by tartrate resistant acid phosphatase staining and the acid phosphatase activity was assayed.The expressions of 5 melanocortin receptors (MCR) in Raw264.7 cells were determined by RT-PCR.The results showed that the number of osteoclasts in RANKL +α-MSH group was significantly increased compared with RANKL group (P ＜ 0.05),but there was no osteoclast formation in α-MSH group.Compared with control group and α-MSH group,the acid phosphatase activities were significantly increased in RANKL group and α-MSH+RANKL group (P＜0.05).All five MCRs were expressed in the Raw264.7 cells shown by RT-PCR.These results suggest that α-MSH may promote osteoclasts formation through RANK signaling pathway.

Objective: To explore the role of clinical pharmacists playing in the pharmaceutical care of adverse drug reactions. Methods:Clinical pharmacist participated in the treatment of one case of coma induced by intramuscular injection of tramadol. After analyzing the medical records and retrieving the concerned literatures,clinical pharmacists thought that it was tramadol inducing the co-ma, and assisted clinicians to make correct diagnosis rapidly, and then provided a reasonable treatment plan according to the pharma-ceutical expertise for clinicians. Results:Clinicians accepted the recommendations and the patient recovered and discharged from the hospital. Conclusion:Clinical pharmacists should participate in clinical treatment team. When facing with adverse drug reactions, clinical pharmacists should think and practise actively, and then play their roles in monitoring adverse drug reactions.

Objective:To investigate the effect of long-term chronic ethanol consumption on the spontaneous discharge activity of Purkinje cells in the cerebellar cortex of mice.Methods:Fifty 3-week-old ICR mice, regardless of gender, were divided into control group and ethanol group according to the random number table method, with 25 mice in each group. The mice in ethanol group were administered 20% ethanol (1.6 g/kg, once a day) by gavage, and the control group mice were given the same volume of 0.9% sodium chloride solution by gavage, and the gavage cycle was 28 days.The electrical activity of cerebellar Purkinje cells induced by sensory stimulation was recorded by patch clamp amplifier and data acquisition software. Statistical analysis was conducted by Clampfit 10.3 software and SPSS 22.0 software, t-test and one-way ANOVA were used to compare the data between the two groups and the data before and after intervention of each group. Results:The electrophysiological results showed that the spontaneous simple spike discharge frequency of Purkinje cells in the cerebellar cortex of mice in ethanol group was lower than that of the control group ((26.8±2.5)%, (34.6±4.7)%; t=26.08, P<0.05), and the coefficient of variation was higher than that of the control group ((27.3±3.3)%, (19.2±2.3)%; t=22.95, P<0.05). After cerebral surface perfusion of GABAA receptor antagonist, the frequency of simple peak potentials in the cerebellar cortex of ethanol mice was higher than before administration ( t=10.19, P<0.05), and the coefficient of variation was lower than before administration ( t=28.36, P<0.05). After brain surface perfusion of GABAA receptor antagonist, there was no significant change in the spontaneous simple peak discharge frequency of cerebellar Purkinje cells in the control group( P>0.05), and the coefficient of variation decreased compared to before administration ( t=6.95, P<0.05). After administering AMPA receptor antagonists on the surface of the brain, there were no significant changes in the discharge frequency and coefficient of variation in both the ethanol group and control group compared to before administration (both P>0.05). After simultaneously blocking AMPA and GABAA receptors, it was found that the spontaneous discharge frequency in ethanol group increased after administration compared to before administration((107.3±4.3)%, (99.7±3.7)%, P<0.05), and the increased value of frequency in the ethanol group was also higher than that of control group ( P<0.05). After simultaneously blocking AMPA and GABAA receptors, the coefficient of variation of the alcohol group and the control group mice were both lower than those before administration (both P<0.05), and the decrease in the alcohol group was higher than that in the control group ( P<0.05). Conclusion:Chronic ethanol exposure significantly inhibited the spontaneous discharge of Purkinje cells in the cerebellum, and the enhancement of inhibitory components was achieved by the inhibitory input mediated by GABAA receptors.

Hispidin is an important styrylpyrone produced by Sanghuangporus sanghuang. To analyze hispidin biosynthesis in S. sanghuang, the transcriptomes of hispidin-producing and non-pro ducing S. sanghuang were determined by Illumina sequencing. Five PKSs were identified using genome annotation. Comparative analysis with the reference transcriptome showed that two PKSs (ShPKS3 and ShPKS4) had low expression levels in four types of media. The gene expression pattern of only ShPKS1 was consistent with the yield variation of hispidin. The combined analyses of gene expression with qPCR and hispidin detection by liquid chro matography-mass spectrometry coupled with ion-trap and time-of-flight technologies (LCMS-IT-TOF) showed that ShPKS1 was involved in hispidin biosynthesis in S. sanghuang.ShPKS1 is a partially reducing PKS gene with extra AMP and ACP domains before the KS domain. The domain architecture of ShPKS1 was AMP-ACP-KS-AT-DH-KR-ACP-ACP. Phylogenetic analysis shows that ShPKS1 and other PKS genes from Hymenochaetaceae form a unique monophyletic clade closely related to the clade containing Agaricales hispidin synthase. Taken together, our data indicate that ShPKS1 is a novel PKS of S. sanghuang involved in hispidin biosynthesis.
