OBJECTIVETo investigate the effectiveness of polycystic ovary syndrome (PCOS) of damp-phlegm constitution treated with embedding therapy on back-shu points and front-mu points and needle-pricking therapy on Sifeng (EX-UE 10).

METHODSEighty-five patients were randomly divided into 2 groups of observation group (42 cases) and control group (43 cases). Embedding therapy on back-shu points and front-mu points and needle-pricking therapy on Sifeng (EX-UE 10) were applied to the observation group. Points such as Zhongwan (CV 12), Guanyuan (CV 4), Tianshu (ST 25), Zhangmen (LR 13), Jingmen (GB 25), Qimen (LR 14), Ganshu (BL 18), Weishu (BL 21), Pishu (BL 20), Shenshu (BL 23), Dachangshu (BL 25) and Xiaochangshu (BL 27), etc. were adopted for embedding therapy. At the same time, needle-pricking therapy on Sifeng (EX-UE 10) was also applied once a week. 0. 5 g metformin hydrochloride tablet was given to the control group, once a day for the first week, and twice a day from the second week. Estimation on therapeutic effect was made for both groups after 3 months treatment. Change of symptoms and signs scores, fasting insulin (FINS), 2 hour insulin after meal (2hINS) and insulin resistance index (HOMA-IR) of both groups before and after treatment were observed, and therapeutic effect estimated.

RESULTSThe total effective rate of the observation group is 97. 6% (41/42), and that of the control group was 95. 4% (41/43). There was no significant difference between the two groups (P>0. 05). Scores of symptoms and signs after treatment were significantly improved in both groups (all P<0. 01), and the observation group was better than the control group (7.01+/-4.23 vs 8. 47+/-2. 82,P<0. 05). Compare with those before the treatment, FINS, 2hINS and HOMA-IR after the treatment were all decreased in both groups (all P<0. 05). The comparison between the two groups showed that differences of FIN had no statistic significance (P>0. 05) after the treatment, while both differences of 2hINS and HOMA-IR had statistic significance [ 2hlNS: (443. 531+/- 93. 90) pmol/L vs (621.29+/-93. 87) pmol/L ; HOMA-IR: 4. 88+/-0. 30 vs 5.06+/-0. 32, both P<0. 05]. The improvement of 2hINS and HOMA-IR in the observation group was better than that of the control group.

CONCLUSIONTreatment of PCOS of damp-phlegm constitution with embedding therapy on back-shu points and front-mu points and needle-pricking therapy on Sifeng (EX-UE 10) have positive effect, which can effectively reduce the insulin resistance, meanwhile, reduce the side-effects of western medication.

Fibers with different hemicellulose contents were produced using various degree removal of hemicellulose to obtain large differences in cellulose and hemicellulose proportions at a similar lignin content. Solid state cross polarisation magic angle spinning carbon-13 nuclear magnetic resonance(CP/MAS ~(13)C-NMR) and atomic force microscope(AFM) had been employed to investigate the microstructure of fibers. The results showed that there was an increase in relative content of para-crystalline cellulose with the decreas of hemicellulose content obtained by the spectral fitting for the cellulose C1-region(δ 102-108). The elementary fibril size was relatively constant between 4.0 and 4.3 nm for the three samples obtained by the spectral fitting for the cellulose C4-region(δ 80-92). The difference in elementary fibril size between the samples was not significant. However, the elementary fibril aggregate size increased from 17.9 to 22.2 nm with the decreas of hemicellulose content, which was a significant change. The results of AFM analysis showed that the fiber with a high hemicellulose content had a porous surface structure. In fibres with a low hemicellulose content, the elementary fibril aggregates formed a much more compact surface structure. Lower hemicellulose content can promote the partially irreversible microfibril aggregation, which caused tensions in the microfibrils due to the finite dimensions of the cell wall, amounting to stress in the microfibrils. However, the porous structure can be improved as hemicellulose content decreased to a certain extent.

Treating different diseases with the same method is a unique original thinking in Chinese medicine, which embodies the spirit of treatment based on syndrome differentiation. We briefly reviewed the origin and development of this concept. We also reviewed that thinking of combination of disease and syndrome is its premise and foundation. We put forward the conditionality of diseases in treating different diseases with the same method by cutting-in modern biological basic researches, that is to say, one kind specific diseases or disease of one specific system. We emphasized the importance of diseases conditionality in treating different diseases with the same method, which was of great significance in studies on combination of disease and syndrome, correspondence of prescription and syndrome, and modern biological basic researches of treating different diseases with the same method.

Objective:China was categorized as one of the 68 countdown countries to achieve the United Nations Millennium Development Goals (MDG) 5. This paper aimed to analyze the situation of maternal survival, and coverage of proven cost effective interventions in China, where specific attention was paid to disparities. Methods: National maternal and child mortality surveillance data were used to estimate maternal mortality ratio (MMR). Coverage for proven interventions was analyzed based on National Health Services Survey, where experts' consultations were made for complementation. Results: There had been a significant reduction of MMR in China, however great disparities existed, with rural Ⅱ to Ⅳ areas experiencing 2 to 5 times higher maternal mortality risks than urban areas and accounting for over 70% maternal mortality burdens. Postpartum hemorrhage, pregnancy associated hypertension, embolism and sepsis were the leading causes, and over 75% of the maternal mortality was caused by preventable or curable causes. Maternal health services utilization decreased in accordance with region' s development level. Socioeconomic factors like financial difficulties were the main obstacles hindering access of care.Even those who made deliveries in hospitals faced different probabilities in receiving qualified care according to their socioeconomic standings. Conclusion: China is on track to achieve MDG 5, however great disparities exist. It is necessary to specifically target rural types Ⅱ to Ⅳ areas. Major causes of maternal mortality which can be prevented or averted through the provision of essential obstetrical care. Yet as compared with maternity health needs, insufficient coverage of maternal and child health (MCH) care services and poor service quality are the leading predisposing factors contributing to maternal mortality in China.

OBJECTIVETo explore the effects of trichloroethylene (TCE) on cardiac developmental differentiation in human embryonic stem cells.

METHODSIn this study, based on the human embryonic stem cells in vitro cardiac differentiation assay, we investigated the potential effect of TCE exposure on the cardiac toxicity in embryo development. Human embryonic stem cells were treated with TCE at different concentrations of 100 ppb, 1 ppm, and 10 ppm and dimethyl sulfoxide(DMSO) treated as control. The MTT assay was performed to examine the cytoplasmic toxicity of TCE exposure. The beating percentages were recorded and the expression of cardiac specific gene was evaluated by PCR or flow cytometry. Also, real time PCR was performed to verify the micro array analysis on the expression level changes of genes which were involved in the Ca2+ signal pathways.

RESULTSCompared with the control group, there was no significant difference in cell viability when cells were treated with TCE at the concentrations of 100 ppb, 1 ppm, and 10 ppm. However, TCE could inhibit the expression of cTnT protein in a concentration-dependant manner. And the most interestingly, TCE significantly inhibited the cardiac differentiation characterized by the decrease beating percentages. Genes involved in Ca2+ signaling pathway were severely disrupted by TCE.

CONCLUSIONTCE inhibited the cardiac specific differentiation of human embryonic stem cell and at the meanwhile the genes responsible for Ca2+ signaling pathway were severely disrupted, which could contribute the severe effects of TCE cardiotoxicity.
