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.

Objective To evaluate the effect and mechanism of HMG-CoA reductase inhibitor simvastatin on experimental interstitial fibrosis. Methods Experiments on rat 5/6 nephrectomy chronic renal failure model and primary cultured renal interstitial fibroblast cells were conducted in this study. The cell proliferation, extracellular matrix, c-fos mRNA expression of rat interstitial fibroblasts were measured by MTT assay, immunohistochernitry, semi-quantitative reverse-transcript PCR methods, respectively. Results Serum cholesterol, triglyceride and creatinine of treated group were significantly reduced by simvastatin as compared with controls. No statistical significance in BUN was observed between untreated and simvastatin-treated rats. Histological examination revealed that simvastatin caused a reduction in the glomeruli with sclerosis. Tubulointerstitial injury paralleled the degree of glomerular damage. Simvastatin in a dose-dependent manner inhibited the proliferation of renal intersititial fibroblasts, decreased the secretion of lamimn( LN), and suppressed the expression of c-fos mRNA, as compared with normal controls. No obvious effect on hyaluronic acid( HA) secretion of fibroblasts was found. Conclusions Simvastatin is anti-proliferative in interstitial fibroblasts and decreases the secretion of laminin. This effect is exerted, at least in part, via inhibition of the c-fos and c-jun-dependent mitogenic pathway. Simvastatin may prevent interstitial fibrosis development and attenuate renal damage in uremic rats with hvperlipidemia.

OBJECTIVETo investigate the permance index ofof portable X-ray fluorescence spectrometer in the determination of lead on filter membrane and to provide data for the determination of lead in workplace air.

METHODSIrradiated with X-ray, the lead would emit specific X-ray fluorescence during the process from the excited state back to the ground state. Rapid determination of lead was completed using fluorescence energy and wave length for qualitative analysis and fluorescence intensity for quantitative measurement. Under set conditions, a series of customized calibration samples were measured to create a standard curve for quantitative analysis of lead on filter membrane.

RESULTSThe regression equation obtained using a portable X-ray fluorescence spectrometer to determine the lead on filter membrane was y=0.004x-0.182 (r2= 0.9999). The linear range was 0.00 -10.40 mg/m3, the minimum detectable concentration was 0.53 µg/m3, and the minimum quantifiable concentration was 1.76µg/m3. The relative standard deviation (RSD) of within-run precision of samples with different concentrations was 0.48%-6.22%, the RSD of between-run precision was 2.51%-5.09%, and the degree of accuracy was in the calibration range of standard samples.

CONCLUSIONPortable X-ray fluorescence spectrometry is a simple, rapid, repeatable, and accurate method for the determination of lead on filter membrane.
