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 expression level of thyroid insulin-like growth factor-Ⅰ (IGF-Ⅰ) in iodine deficiency and excess mice and the effect of thyroid gland IGF-Ⅰ in the thyroid morphological change. Methods Forty-eight Balb/c mice were chosen as studied objects,weighing about 16 g. They were divided into three groups: low iodine(LI,iodine content of 50 μg/kg in feed,drinking deironized water) group,normoi(NI,iodine content of 300 μg/kg in feed,drinking deironized water) group and high(HI,iodine content of 300 μg/kg in feed,iodoine of content 14 700 μg/kg in drinking) group,16 mice in each group. Mice were put to death after 12 weeks and taken out of their thyroid gland. The body weight,absolute and relative weights of thyroid gland were measured and the morphological change of thyroid gland were observed under microscope. The expression levels of thyroid gland IGF-Ⅰ mRNA and protein were detected by RT-PCR and immunohistochemistry,respectively. Results There were statistical significances between groups of thyroid absolute and relative weights(F = 315.881,405.921,all P < 0.01). LI group [(10.71±4.03) mg,(44.98±15.39)mg/100 g body weight]and HI group [(3.42±1.17)mg,(13.50± 3.89)mg/100 g body weight]had heavier thyroid absolute and relative weights than NI group[(2.11±0.53)mg,(8.35±1.98)mg/100 g body weight,all P < 0.01]. Under microscopy,the thyroid follicle capacity grew down and the follicle quantity grew up in LI group,the epithelium was stylolitic,the colloid diminished or absence in follicular cavity,while HI group presented colloid accumulation without follicular hyperplasia. The expression level of thyroid gland IGF-Ⅰ mRNA in LI group(1.03±0.32) was more than that in NI(0.65±0.19) and HI(0.59± 0.20) groups(F= 7.518,P< 0.01). In contrast to NI,there was no difference in the expression level of thyroid gland IGF-Ⅰ mRNA in HI group(P > 0.05). The brownish particles of LI group were more than NI and HI groups in the thyroid follicle epithelium by immunohistochemistry,while HI group was less than NI group. Conclusions The mice of iodine deficiency presented follicular hyperplasia goiter,the mice of iodine excess presented colloid accumulative goiter. The change of IGF-Ⅰ mRNA and protein expression may participate morphologleal change,indicating autocrine IGF-Ⅰ of thyroid gland may play an important role in regulating goiter formation.

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.
