Insulin resistance model of 3T3-L1 adipocytes were prepared with plamotic acid.Adipocytes with generated insulin resistance were cultured with different concentrations of globular domain of adiponectin(gAd:250,500,1 000 ng/ml).The cell culture medium glucose content was detected with the glucose oxidase method,the mRNA expressions of insulin receptor substrate-1 (IRS-1),phosphatidylinositol-3 kinase(PI3K),and protein kinase B(PKB) were detected with real-time quantitative PCR method.The phosphorylation of IRS-1 was detected by Western blot.Compared with the control group,the experimental group showed significantly increased glucose consumption (P ＜ 0.01),and with the increasing gAd concentration,glucose consumption was gradually increasing.IRS-1 phosphorylation was increased gradually with the increasing concentration of gAd.These results suggest that gAd can promote glucose uptake by 3T3-L1 adipocyte model with generated insulin resistance.This may be correlated with promoting insulin signal transduction and improving insulin resistance in adipocytes.

Chinese medicine has developed rapidly in the world, but the international standard system has not been established, further affecting the healthy development of Chinese medicine. Technical status of the member states are closely related to the current legislation and regulations in the development of Chinese medicine, which is important for developing international standards for TCM strategies. By the findings of ISO Technical Committee of Traditional Chinese Medicine (ISO/TC249) 7 European P member (Participating countries) International Traditional/Alternative Medicine (TM/CAM) legislative status, herbal medicine in each member country has a large market, a good environment for the development of some countries. After“The EU Traditional Herbal Medicinal Products Directive 2004/24/EC”issued by the member states for the registration and management in European, regulation of herbal products become more stringent. There are relatively small quantity of TM/CAM practitioners, lack of education for practitioners and standardized management.

OBJECTIVETo explore the clinical efficacy and action mechanism of acupuncture for premature ovarian failure (POF).

METHODSAccording to prospective cohort study design, 30 cases were included. Based on theory of regulating Chong and Conception Vessels as well as soothing the liver and calming the nerves, acupuncture at Guanyuan (CV 4), Dahe (KI 12), Taixi (KI 3), Taichong (LR 3), Baihui (GV 20) was applied, three times per week and 3 months were considered as one session. Totally two sessions were performed. The menstruation condition, estradiol (E2), follicle-stimulating hormone (FSH) and scores of the clinical perimenopausal symptoms were taken as treatment outcomes.

RESULTSThe total effective rate was 86.7% (26/30) and the cured rate was 16.7% (5/30). The recovery rate of menstruation was 16.7% (5/30) and the regain rate of menstruation was 56.7% (17/30). After the treatment, the level of E2 was significantly increased from (45.41 +/- 18. 09) pmol/L to (59.07 +/- 24.21) pmol/L (P < 0.05), and the score of perimenopausal symptoms was obviously reduced from 14.28 +/- 8. 30 to 4.04 +/- 3.28 (P < 0.01). However, no statistical differences could be seen in FSH before and after treatment (P > 0.05).

CONCLUSIONAcupuncture has certain effect on improving menstruation and perimenopausal symptoms in POF patients, which is likely to he related with increasing the level of E2.

Objective To study the effects of oxymatrine as inhibitor of hemorrhagic fever with renal syndrome virus (HFRSV) infection in vitro and in vivo.Methods In vitro studies,a dose of oxymatrine without cytotoxicity and 76-118 strain of HFRSV was taken to treat Vero cells in three ways:①After treated with oxymatrine for 48 h,Vero cells were attacked by HFRSV at dilution of 10-1 ～ 10-6,respectively for 24 h before changing to maintenance medium; ②Vero cells were first attacked by HFRSV of 10-1 ～ 10-6 dilution respectively,then oxymatrine was used for 48 h before changing to maintenance medium; ③Vero cells were attacked by HFRSV at dilution of 10-1 ～ 10-6 respectively,and meanwhile treated with oxymatrine for 48 h before changing to maintenance mcdium.Each dilution handled four porocytes,and four positive controls were set up at the same time.Indirect immunofluorescence assay (IFA) was performed to determine the inhibitory effect of oxymatrine in experimental group and positive control.In vivo studies,thirty 2-week-old hamsters,weighing about 30-40 g,were divided into experimental and control groups according to body weight,n =15.These aninals were inoculated intraperitoneally with HFRSV in 100TCID50(0.1 ml each); on days 4-13,0.1 ml of oxymatrine 1:100 were given to each hamster in experimental group daily by intraperitoneal injection,while the same amount of saline was given to the control ones.Lung tissue of hamsters was then dissected out to slice to be identified by immunofluorcscence stain.Results It was demonstrated that oxymatrine with the diluted fractions of 1:8 was safe in vitro.When the virus dilution of HFRSV was l0-4,compared with control groups,the differences were statistically significant in method 2 and 3 (z =-2.53,-2.53,all P ＜ 0.05),while no statistical significance in method 1 (z＝5.36,P＞ 0.05).When the virus dilution of HFRSV was 10-1 ～ 10-3,10-5,10-6,the differences were not statistically significant (z--0.00,-0.32,-0.19,4.21,4.21,all P ＞ 0.05).In vivo studies,compared with control group,the differences were statistically significant in experimental group (z =-3.85,P ＜ 0.05).Conclusion Oxymatrine significantly inhibites HFRSV.

In traditional oral practice, the presystemic interactions with gut microbiota is an important mechanism underlying the holistic health benefits of Chinese herbal medicines (CHMs), making the study of CHMs distinct from the research of Western medicines of which the systemic exposure (level in blood) is the starting point and the core. Gut microbial metabolism complements host metabolism in maintaining metabolic homeostasis of many biologically important endogenous molecules and the disposition of numerous exogenous compounds. Among them, the widely distributed gut bacterial β-glucuronidases (BGUSs) coordinate with host UDP-glucuronosyltransferases (UGTs) to play a role in the occurrence and intervention of diseases by affecting the glucuronidation homeostasis and altering the intestinal local and/or systemic exposure of endogenous compounds and xenobiotics. On one hand, many ingredients of CHMs undergo enterohepatic circulation; On the other hand, CHMs can act on BGUSs directly or indirectly change the distribution and function of BGUSs through reprogramming gut microbiome. The multiple interactions between BGUSs and CHMs may play an important role in the overall therapeutic benefits of CHMs. This work firstly summarizes the latest research progress on BGUSs; then the physiological, pathological and pharmacological significance of BGUSs are exemplified with representative endogenous and exogenous compounds from the aspects of nutrient utilization, metabolic homeostasis, and therapeutic response based on the varied substrate spectra of BGUSs; finally, the scattered data in literature were integrated to summarize the multiple interactions between BGUSs and CHMs, highlighting the important role of BGUSs in the holistic actions of CHMs.

Objective To study effect of excessive iodine intake on sodium-iodide symporter(NIS)mRNA and protein expression of breast in lactating rats.Methods60 Wistar rats,having been weaned for one month,were randomly divided into three groups according to their body weights,I.e,①normal iodine(NI,30 rats);②ten fold high iodine(10 HI,15 rats);③one hundred fold high iodine(100 HI,15 rats).Eating food containing iodine of 300μg/L and drinking water of iodine at 5,1845,20 295μg/L,respectively.After fed for 3 months,the rats mated and had offspring,and urine and milk iodine of lactating rats were determined by As-Ce-catalytic spectrophotometric method.Their marmnary glands were sampled at lactation day 10.Then NIS mRNA expression by RT-PCR was determined and NIS protein by immunohistochemistry(SABC)was observed.Results The urine iodine of 10 HI group(3597.5μg/L)and 100HI group(25 404.3μg/L)increased obviously compared with that of NI group(344.7μg/L).The milk iodine of 10HI group(27.1×103μg/L)and 100HI group(191.0×1μg/L)was higher than that of NI group(6.0×103μg/L),but the increased fold of milk iodine was not paralleled with that of urine iodine.Difference of NIS mRNA expression was significant(F=24.19,P＜0.01)among the groups,and the NIS mRNA expression in 10HI(1.250±0.034)and 100HI(1.272±0.039)group were less than that in NI (1.532±0.044)group(P＜0.01).The breast NIS mRNA expression in lactating rats(1.532±0.044)was significantly higher than that in unlactating rats(0.879±0.018,P＜0.01).With the increasing iodine uptake,NIS protein expression decreased.Conclusions The NIS mRNA and protein in rat breasts is down-regulated by excessive iodine intake.So increasing extent of milk iodine concentration is inhibited,which is important to prevent off-spring from getting excessive iodine intake from parental generation.

OBJECTIVETo evaluate the efficacy and safety of Chinese herbal medicine combined with systemic chemotherapy and/or regional arterial perfusion for pancreatic cancer with liver metastases (PCLM).

METHODSWe retrospectively selected 292 patients with PCLM who were treated by Chinese herbal medicine combined with systemic chemotherapy and/or regional arterial perfusion at Tianjin Medical University Cancer Hospital from January 2001 to December 2010. All patients were assigned to the Western medicine treatment group (157 cases) and the integrative medicine treatment group (135 cases). Patients in the Western medicine treatment group were treated with gemcitabine (GEM)-based chemotherapy, and partial of them received regional arterial perfusion. Those in the integrative medicine treatment group additionally took Chinese herbs of clearing heat and eliminating mass for at least 4 weeks. The median survival time (MST) , adverse reactions and the incidence of complications were observed.

RESULTSThere was no statistical significance in general data between the two groups (P > 0.05). There was statistical difference in MST between the two groups (4.8 months vs 5.5 months, P < 0.05). No death occurred during chemotherapy or regional arterial perfusion. All toxic or adverse reactions were tolerable.

CONCLUSIONChinese herbal medicine combined with systemic chemotherapy and/or regional arterial perfusion was effective and safe, and it could be optimally selected as palliative therapy for PCLM.
