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.

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.

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.

Background and purpose:Curcumin is the major effective component of curcuma,curcumin has been noted to be able to selectively inhibit proliferation and induce apoptosis in tumor cells. Interferon-?(IFN-?) is one of the most important cytokines used in clinical treatment nowadays. This study was made to investigate the inhibitory effect of interferon-?(IFN-?)and curcumin on Raji cells (B-NHL) and discuss their mechanism.Methods:The variations of morphology of Raji cells were observed in culture medium after being treated by IFN-?(500,100,2000U/L) combined with various concentrations of curcumin (6.25,12.5,25?mol/L), cells were incubated with the compounds for variable times.The inhibitory ratio was measured by MTT assay, apoptosis was quantitated by flow cytometry(FCM) and the expressions of caspase6, caspase8 and caspase9 in Raji cells were detected by Western blot.Results:both IFN-? and curcumin could significantly induce apoptosis and inhibit the proliferation of Raji cells, synergistic effects were found if cells were treated by the combination of IFN-? and curcumin. The overexpressions of caspase6, caspase8 and caspase9 in Raji cells could be observed in a time-and dose-dependent manner.Conclusions:The combination of IFN-? and curcumin could synergistically inhibit proliferation and induce apoptosis, and its potential mechanism is probably associated with upregulating the expressions of caspase6, caspase8 and caspase9 in B-NHL Raji cell.

Aim To investigate the effect of selective cyclooxygenase-2 inhibitor, NS-398, on cell apoptosis in leukemia cell line K562 cells and its underlying mechanism. Methods Apoptotic cell percentage was examined by flow cytometry(FCM). The protein expression of Bcl-2 and Caspase-3 was detected by Western blot, and the activity of Caspase-3 was checked by FCM. Results NS-398 induced the cell apoptosis in K562 cells in a dose-dependent manner. After NS-398 treatment, the expression of Bcl-2 protein was downregulated, whereas the expression of Caspase-3 protein was upregulated. Moreover,the activity of Caspase-3 was increased in a dose-dependent way after NS-398 treatment. Conclusion Selective cyclooxygenase-2 inhibitor,NS-398,significantly induced apoptosis in K562 cells. The underlying mechanism might be related to the downregulation of Bcl-2 and the activation of Caspase-3.

Objective To study the connection between vascular endothelial growth factor(VEGF) and pool prognosis in nephroblastoma.Methods Serum VEGF was measured with immuneohistochemical(ELISA) methods in 35 children of nephroblastoma at preope-ration,1 week,2 weeks after surgery respectively. Simple visiting happened after surgery 4,8,16,32 weeks.The countrol group was 35 healthy children. Result Before surgery,the median VEGF in the children was (89.47?22.45) ?g/L.After surgery 1 week,2 weeks,levels in the children fell significantly to (2.75?0.31) ?g/L,(1.52?0.18) ?g/L.There was a significant difference compared with preoperation ( t =4.125 P

Aim To investigate the effect of Trichostatin A(T SA)on histone deacetylase (HDAC1) and P21 WAF1/CIP1,cyclin dependent ki nase inhibitor,in NB4 cells for exploring the underlying mechanism of TSA in an ti-leukemia.Methods The total proteins and P21 WAF1/CIP1 mRN A were extracted from acute promyelocytic leukemia NB4 cells treated with or wit hout TSA of different concentrations at different time points,Western blot anal ysis was performed to determine the level of HDAC1 and P21 WAF1/CIP1 protei n,respectively,and RT-PCR was performed to detect the level of P21 WAF1/CI P1 mRNA.Results (1)The level of HDAC1 was obviously inhibited by TSA,and had decreased at 4 hours at IC 50 and lasted for 48 h. The inhibi tion of HDAC1 was significant at the TSA concentration of 37.5 nmol?L -1 , but there was no difference between 75~300 nmol?L -1.(2)The levels of P21 WAF1/CIP1 mRNA and protein were up-regulated by TSA in dose-and ti me-dependent manner,and mRNA increased in 8 h,but the P21 WAF1/CIP1 prot ein was detected at 12 hours and lasted for 48 hours.Conclusion TSA could inhibit the level of HDAC1 and enhance the expression of P21 WAF1/CIP1 protein and mRNA,and the results suggest that inhibiting HDAC1 and increasin g P21 WAF1/CIP1 may be one of the possible mechanisms of anti-leukemia by TSA.
