OBJECTIVETo establish the quality standard of Entadae Semen, and provide scientific basis for its quality control.

METHODTLC and HPLC were used for qualitative identification and quantitative analysis of phaseoloidin and entadamide A-O-β-D-glucopyranoside in Entadae Semen. The test of water content, ash and ethanol-soluble extractives of Entadae Semen was carried out according to the methods recorded in appendix of Chinese Pharmacopeia (2010 edition).

RESULTThe TLC was well separated with clear spots. The linear range of phaseoloidin was between 0.014 to 2.747 g x L(-1) (r = 0.999 6, n = 9) with an average recovery rate of 101.06% (RSD 0.90%, n = 6); the linear range of entadamide A-O-β-D-glucopyranoside was between 0.002 to 0.452 g x L(-1) (r = 0.999 7, n = 9) withan average recovery rate of 101.52% (RSD 1.09%, n = 6). The content of phaseoloidin in sample is between 5.12% to 9.24%, entadamide A-O-β-D-glucopyranoside is between 0.55% to 2.17%, alcohol-soluble extracts is between 30.9% to 45.2%, water is between 6.6% to 8.6%, and total ash is between 2.4% to 2.9%.

CONCLUSIONThe established standard is acceptable for quality control of Entadae Semen.

ObjectiveTo study the effct of the early rehabilitation of acute stroke with acupunction added to rehabilitational training.Methods120 patients with acute stroke were divided into 2 growps with 60 cases each:the acupunction growp,in which the patients were acepted acupuncture added to rehabilitational training,and the control growp,in which the patients were acepted the rehabilitational training only.All the patients were evaluated with Clinical Nervous Functional Deficiency(CNFD),Fugl-Meyer Assessment(FMA) and Modified Barthel Index(MBI).Results The scales of CNFD,FMAanal Deficiency (CNFD),Fugl-Meyer Assess me that of the control growp.The rate of cure and significantly in the acupunction growp was 75%,while that of the control growp was 41.7%(P<0.01).Conclusions Acupunction compared with the rehabilitational training is effective on the with stroke.

In recent years, polysaccharides have received much attention because of their high safety and good immunological activity. The study of polysaccharide in vivo process is a key scientific problem that needs to be solved for polysaccharide drug development. Some progress has been made in the field of polysaccharide pharmacokinetics and immunomodulation. However, due to the lack of both chromogenic and light-absorbing groups and the complex molecular structure of polysaccharides, the in vivo processes and immunomodulatory mechanisms of polysaccharides have been slow to be investigated. The effective combination of multiple techniques can break the bottleneck of difficult tracing and unknown immunomodulatory mechanism of polysaccharides in vivo, and promote the development and utilization of polysaccharides. In this paper, we systematically summarize the key techniques in the study of polysaccharide in vivo processes and immunomodulatory mechanisms in order to provide technical references and research ideas for the study of polysaccharide in vivo processes and immunomodulatory mechanisms.

Objective:To investigate the immune response after injecting polysaccharide nucleic acid of Bacillus Calmette-Guerin(BCG-PSN)under the mucous membrane of bladder in rabbits and to search for the most suitable dose of BCG-PSN.Methods:The rabbits were randomly divided into 5 groups:high dose(0.35 mg/ml)BCG-PSN group,mid- dle dose(0.175 mg/ml)BCG-PSN group,low dose(0.0875 mg/ml)BCG-PSN group,BCG(0.35 mg/ml)control group and BCG-PSN(0.35 mg/ml)intra-bladder perfusion control group.T lymphocyte subsets(CD4~+,CD8~+)in the peripheral blood were determined by flow cytometry before and 1 week,2 weeks,1 month and 3 months after the treatment; the levels of IL-2,TNF-?,and IFN-?of peripheral blood were determined by enzyme-linked immunosorbent assay;H-E and Masson staining was used for the pathological examination of the bladder.Results:(1)BCG-PSN injection increased the number of CD4~+ and CD8~+ T lymphocytes in a time- and dose-dependent manner,with the peak numbers appeared 2 weeks after BCG-PSN injection;the numbers restored to the normal levels 3 months after BCG-PSN injection.BCG control group had a similar changing pattern to the BCG-PSN injection group.The number of CD4~+ T cells BCG-PSN perfusion group was significantly lower than that in the high-dose BCG-PSN injection group(P

Objective To evaluate the efficacy and safety of adefovir dipivoxil(ADV)in treating patients with hepatitis B e antigen(HBeAg)positive chronic hepatitis B.Methods In this randomized,double blind,placebo-controlled,multicenter trial,210 eligible patients with HBeAg positive chronic hepatitis B were recruited and randomized(randomization ratio was 2:1)receiving ADV 10 mg/d for 48 weeks(ADV+ADV group,n=142)or placebo for 24 weeks followed by ADV 10 mg/d for 24 weeks(PLB+ADV group,n=68).The primary endpoint was virological response. The secondary endpoint was serologic response(HBeAg loss rate and HBeAg seroconversion rate) and alanine aminotransferase normalization rate.Results After 24 weeks therapy,mean reduction of hepatitis B virus(HBV)DNA level comparing with that of baseline was 3.12 log_(10)copy/mL in ADV +ADV group while it was 0.95 log_(10)copy/mL in PLB+ADV group.The percentages of patients with HBV DNA clearance(HBV DNA level

RNA-Sequencing (RNA-Seq) is a newly-developed method in transcriptome research, it can afford more accurate transcription information and be more quickly by using Next-generation Sequencing (NGS) technology. RNA-Seq has been widely used in various biological fields. Genuine traditional Chinese medicines (TCM), with good quality and therapeutic effect, were always praised highly and used by famous physicians. The geo-herbalism formation of TCM is based on the product of the gene expression at specific space and time. So it has been a research hotspot to analyze the mechanism of biosynthesis through RNA-Seq in the study on the secondary metabolism of medicinal plant. This article mainly illustrates the RNA-Seq and its advantages, it also discusses the potential application in genuine TCM, and it can provide useful information for other researchers.

The effect of obesity on idiopathic central precocious puberty (ICPP) girls is still under discussion.The relationship between body mass index (BMI) and sexual hormone levels of gonadotropin-releasing hormone (GnRH) stimulation test in ICPP girls is controversial and the underlying mechanism is unclear.This study aims to further explore the independent effect of excess adiposity on peak luteinizing hormone (LH) level of stimulation test in ICPP girls and the role of other related factors.A retrospective cross-sectional study was performed on 618 girls diagnosed as having ICPP,including 355 cases of normal weight,99 cases of overweight and 164 cases of obese.The results showed that obese group had more progressed Tanner stage and no significant difference (P=0.28) in LH peak was found as basal LH value was used as a covariate.The obese group had higher total testosterone (TT),adrenocorticotrophic hormone (ACTH),17-α hydroxyprogesterone (17-αOHP) and androstendione (AN),with significantly increased fasting insulin (FIN) and homeostasis model of assessment for insulin resistance index (HOMA-IR).Stratified analysis showed inconsistency of the relationship between BMI-standard deviation score (BMI-SDS) and LH peak in different Tanner stages (P for interaction=0.017).Further smoothing plot showed linear and non-linear relationship between BMI-SDS and LH peak in three Tanner stages.Then linear regression model was used to analyze the relationship between BMI-SDS and LH peak in different Tanner stages,with and without different confounding factors being adjusted.In B2 stage,BMI-SDS was negatively associated with LH peak.In B3 stage,when BMI-SDS ＜1.5,as BMI-SDS increased,the level of LH peak decreased (model Ⅰ:β=-1.8,95％ CI=-4.7 to 1.1,P=0.214).When BMI-SDS ≥1.5,BMI-SDS was significantly positively associated with LH peak (model Ⅰ:β=4.5,95％ CI=1.7 to 7.4,P=0.002).In B4 stage,when BMI-SDS ＜1.5,BMI-SDS was negatively associated with LH peak (model Ⅰ:β=-11.6,95％ CI=-22.7 to-4.5,P=0.049).When BMI-SDS ≥1.5,BMI-SDS was positively associated with LH peak (model Ⅰ:β=-4.2,95％ CI=-3.3 to 11.7,P=0.28).It is concluded that there is an independent correlation between BMI-SDS and LH peak of stimulation test in ICPP girls,their relationships are different in different Tanner stages,and the effect of BMI-SDS can be affected by adrenal androgens,estradiol and glucose metabolism parameters.
