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.

With the development of society and the improvement of people's living standards, the effect of Chinese medicine in treatment and health care is more and more prominent. The herbal decoction pieces are the important part of Chinese medicine,it can be applied directly to clinical treatment and it's also the raw material of Chinese patent medicine. Therefore, the quality of herbal decoction pieces is quite important. The parts of the production of herbal decoction pieces are numerous, and there are possibilities of adverse effects on the quality of the herbal decoction pieces in every part. In this paper, we based on the production chain of herbal decoction pieces, analyzed the main problem that affect the quality of herbal decoction pieces in the part of selection of Chinese herbal medicines, planting, purchasing, processing, packaging, storage and transport, such as the poor quality of seed and seedlings of plant-based Chinese medicines, some plants left their place of origin and have been introduced in the place that is not suitable for this kind of plant, the insufficient growth time and the excessive harmful substances. The purchasers and the accepters lack of professional knowledge and professional ethics. The mechanism of processing is not clear, the standards can not be uniformed, and lack of qualified person in processing, etc. So we suggest: intensify the basic research of key scientific issues. Improve the quality of persons who work in herbal decoction pieces; Establish an "integration" mode of operation in herbal decoction pieces enterprise; Breeding high quality plant resources, establish the large-scale planting basement; Make the packing of herbal decoction pieces standard; Establish the modernization traditional Chinese medicine logistics enterprise.

Berberine (BBR) is a type of alkaloids isolated from Coptidis Rhizoma and Phellodendri Chinensis Cortex and has been used to treat bacterial gastroenteritis, diarrhea and other digestive diseases for more than 1 000 years. According to recent studies, berberine has been found to have multiple pharmacological activities, including lowering blood glucose and lipid, anti-inflammation, antioxidation, relieving type 2 diabetic nephropathy (DN), diabetic cardiovascular disease, diabetic peripheral neuropathy ( DPN) and other complications. In this article, the authors summarized the literature reports about the effects of BBR in lowering blood glucose and preventing and treating the above type 2 diabetes and its complications, in order to provide reference to further studies and promotion of BBR's application.

Histone deacetylase (HDAC1) has a high expression in many cancer cells and curcumin can inhibit the growth of cancer cells. This paper was designed to investigate the expression of HDAC1 of Raji cells and the effect of curcumin on their proliferation and apoptosis. Raji cells were treated with 3.125-50 micromol/L curcumin for 8-48 h and the growth inhibition rates of Raji cells were measured by MTT. The expression of HDAC1 on Raji cells were examined by mRNA, Western blot at 24 h various concertrations (1.6-50 micromol/L). Curcumin could selectively inhibit the proliferation of Raji cells in a dose- and time-dependent manner, with the inhibition rate being 52.47 %-82.18 % (P<0.01). The up-regulation of HDAC1 expression was observed within 24 h after the treatment with curcumin as shown by RT-PCR and Western blot. With the increase of concentration, the expression was down-regulated in a dose- dependent manner. It is concluded that the expression of HDAC1 plays an important role in the proliferation and apoptosis of Raji cells and curcumin can inhibit the growth of Raji cells at various concentrations and promote the apoptosis of Raji cells.
