Objective To observe the clinical efficacy of abdominal acupuncture in treating perimenopausal insomnia.Method Sixty patients with perimenopausal insomnia were randomized into a treatment group and a control group, 30 in each group. The treatment group was intervened by abdominal acupuncture, while the control group was by regular body acupuncture. The FSH, LH, and E2 contents, and Pittsburgh Sleeping Quality Indext (PSQI) were observed before and after intervention, and the clinical efficacies were compared.Result The total effective rate was 90.0% in the treatment group versus 86.7% in the control group, and the difference was statistically insignificant (P>0.05). The PSQI score was changed significantly in both groups after intervention (P<0.01). After intervention, there was no significant difference in comparing PSQI score between the two groups (P>0.05). The FSH, LH, and E2 contents were significantly changed after intervention in both groups (P<0.01). After intervention, there were no significant differences in comparing FSH, LH, and E2 contents between the two groups (P>0.05).Conclusion Abdominal acupuncture in an effective method in treating perimenopausal insomnia.

Objective To investigate the efficiency of levodopa in dopa responsive dystonia (DRD) patients and drugs safety in pregnancy cases confirmed by genetic detection.Methods The clinical characteristics of two patients were analyzed.Direct sequences were performed in guanosine triphosphate (GTP) cyclohydrolase Ⅰ (GCH1) gene and tyrosine hydroxylase (TH) gene mutation screening.Results Case 1 was a young man exhibiting writer's cramp and dystonia of lower legs with marked diurnal fluctuation.Writer's cramp could not be relieved by treatment of low dose levodopa/benserazide.After increasing dose,the symptom of writer's cramp appeared occasionally.Case 2 was a young woman who experienced gait disorder.The symptom disappeared completely by levodopa treatment.She used levodopa and benzhexol during pregnancy.By 38 gestational weeks,she gave birth to a healthy baby.Sequence analysis of GCH1 gene in case 1 revealed a mutation (c.230C ＞ G p.S77C) that is a novel pathogenic mutation.The confirmed mutation c.628delC (p.His210Thrfs* 5) found in case 2 had been reported previously.No mutations in TH gene were detected in two patients.Condnsions Most of DRD patients have dramatic response to levodopa,but patients exhibited writer' s cramp may respond to levodopa incompletely.The previous reports indicate that no adverse events have been reported in DRD pregnant women with the monotherapy of levodopa.

This paper is discussed about course system construction of Microbiology, teaching method, in- struction means and experimental teaching mode. Teaching practice indicated that reform the pattern of Mi- crobiology educational mode can stimulate students’ interest in studying the course, cultivate their inde- pendent ability to solve questions, develop their creative thinking. It is an important way to train high-caliber talents.

Objective To construct RNAi combinant adenoviral expressive vectors specific to p65 subunit of NF-?B and to observe their gene silencing effect on p65 subunit.Methods Three pairs of complementary. single-strand DNA oligos targeting three various sites of p65 mRNA were designed and synthesized.Annealling was used to generate double-strand oligos(ds-oligos),and then the ds-oligos were cloned into pENTR~TM/u6 to generate the entry clone named pENTR.Recombination reaction in vitro with the pENTR and pAd/BLOCK-iT~TM- DEST was used to creat the adenovirus plasmid which contains the RNAi cassette.Then,the adenovirus plasmids digested with PacI were transfected into HEK293A cells to product adenovirus,and latter infected the HEK293A cells to amplify the adenoviral stock.Plaque forming assay was used to titer the adenoviral stock.The p65 gene silencing effect induced by the RNAi adenovirus was detected by Western blot and immunocytochemistry assay in ECV304 cells.Results The RNAi adenovirus specific to p65 subunit of NF-?B were produced with titer of 3.0 x 10~9pfu/ml to 2.5?10~10pfu/ml.The expression of p65 protein in ECV304 cells could be down-regulated efficiently by the RNAi adenovirus 48-72 h after infection,which would last for more than 6 days after infection.Conclusion RNAi adenovirus is an important tool inhibiting the expression of target gene efficiently.

The objective of the present study was to establish a method based on principal component analysis (PCA) for the study of transdermal delivery of Chinese medicinal formulae, and to choose the best penetration enhancers for Qingfei Xiaocuo gel depend on this method. Using improved Franz type diffusion cell and excised rat skin in vitro as transdermal barrier, the receptive solution fingerprint was established by HPLC, harvesting the areas of the common peaks in the fingerprint, then the total factor scores of the concentrations at different times were calculated using PCA and were employed instead of the concentrations to compute the cumulative amounts (Q12) and enhancement ratio (ER), the latter of which were considered as the indexes for optimizing penetration enhancers. Compare to the control group, the ER of the other groups increased significantly and furthermore, 2.5% azone with 2.5% menthol manifested the best effect. PCA represent most information in the receptive solution, the method above could choose the best penetration enhancers, it could be a reference for the study of transdermal delivery of Chinese medicinal formulae.

Objective To explore the characteristics of proinsulin secretion in latent autoimmune diabetes in adults (LADA). Methods Fasting and 2 h sera in oral glucose tolerance test from 36 LADA patients, 37 type 2 diabetic patients and 43 healthy controls were collected to test glucose, proinsulin (PI) and C-peptide (CP) by radioimmune assay. Glutamie acid decarboxylase antibodies (GAD-Ab) were determined by radioligand assay.Results (1) Fasting proinsulin (FPI) and 2 h proinsulin (PPI) level in LADA patients were lower than those in type 2 diabetic patients (P<0.05), being both significantly inereasad compared with healthy controls (P<0.05 or P<0.01); The ratios of FPI/FCP and PPI/PCP (%) in LADA were beth significantly higer than those of type 2 diabetes mellitus and controls (P<0.05 or P<0.01); (2) LADA type-1 (GAD-Abe>0.3) patients showed lower PI levels(P<0.05 or P<0.01) and higher PI/CP ratio (all P<0.05) than LADA type-2 (0.05≤GAD-Ab<0.3); Meanwhile, there were no significant differences in above parameters between LADA type-2 and type 2 diabetes meUitus (P>0.05). (3) GAD-Ab index was negatively correlated with FPI and PPI in LADA group (r=-0.236 and-0.268, both P<0.05), and positively correlated with PPI/PCP (r=0.254, P=0.030).Meanwhile BMI was positively correlated with FPI, PPI and PI/CP in type 2 diabetes mellitus (all P<0.01). No factor entered the multiple regression analysis for predieting the hyperproinsulinemia and dispropriately elevated proinsulin levels in LADA patients. (4) According to the 99.5 th percentile of proinsulinemia in the healthy controls, which is defined as the cutoff point dispropriately elevated proinsulin levels, the proportion of subjects with fasting dispropriately elevated proinsulin levels (FPI/FCP) were 77.8%, 62.2% and 2.3% in LADA, type 2 diabetes meUitus and controls respectively, and PPI/PCP 83.3%, 51.4% and 2.3% respectively. Conclusion LADA patients, as well as type 2 diabetic patients, all showed hyperproinsulinemia and disproportionately elevated proiasulin levels that were one of characteristics of defective β-cell function. Moreover, disproportionately elevated nproinsulin level is more evident in LADA patients than that in type 2 diabetics and this may be related to humoral immunity.

To investigate the anticancer effects of ring C in 18β-glycyrrhetinic acid (GA), a series of GA derivatives featured with 9(11)-ene moiety in ring C were designed and synthesized. The structures were confirmed by IR, LC-MS and 1H NMR. Their inhibitory effects towards human prostate cancer PC-3 and leukemia HL-60 cell lines were determined. Most of the derivatives displayed stronger antiproliferative activities than GA. Particularly, compound 14 showed promising anticancer activity with the GI50 values of 4.48 µmol · L(-1) and 1.2 µmol · L(-1) against PC-3 and HL-60 cells respectively, which is worth further study.
