Infect of pingshen decoction on serum HGF, Cys C and TGF-beta1 diabetic nephropathy in early stage / 中国中药杂志

Study the serum level of HGF, Cys C and TGF-beta1 in type 2 diabetic nephropathy (DN), the infect of Pingshen decoction on those index. Selected 69 cases of 2 type DN and randomly divided into therapy group (36 cases) and control group (33 cases). The therapy group were treated with Pingshen decoction 1 dose/d, bid po. The control group were treated with NephritisShu tablet, 6 tablet, tid po. 8 weeks was a course. Before and after treatment, we examine the serum level of HGF, Cys C and TGF-beta1 by ELISA and immunonephelometry, and compare with 30 cases of healthy control group. The study demonstrates that before treatment, the serum level of HGF in both groups were significantly lower than healthy control group (P < 0.01), but Cys C, TGF-beta1 were significantly higher (P < 0.01). After treatment, the serum level of HGF of both groups were increased. The serum level of HGF of therapy group were significantly higher than of control group (P < 0.01), but the serum level of Cys C and TGF-beta1 were significantly lower than control group (P < 0.01). The serum level of HGF was correlated negatively with Cys C,TGF-beta1. In control group, the UAER, urine beta2-MG and quantity of 24-hour urine protein were significantly decreased after treatment (P < 0.01). The index of urine of therapy group were significantly lower than control group (P < 0.01). Results indicate that test of serum level of HGF and Cys C,TGF-beta1 of diabetic nephropathy have important clinical significance. Pingshen decoction can effectively intervene in the serum level of HGF and Cys C, TGF-beta1 and index of urine.

Impacts on the appetite regulating factors of infantile anorexia treated with acupuncture at Sifeng (EX-UE 10) / 中国针灸

<p><b>OBJECTIVE</b>To explore the dynamic change and clinical efficacy of acupuncture at Sifeng (EX-UE 10) on appetite regulating factors in the serum of infantile anorexia.</p><p><b>METHODS</b>Eighty cases, in compliance with the diagnostic criteria, aged from 3 to 6 years were randomized into an acupuncture group and a medication group, 40 cases in each one. Additionally, a healthy control group (30 cases) was set up. In the acupuncture group, the pricking method was adopted at Sifeng (EX-UE 10) with the three-edged needle. A few light yellow, transparent viscous liquid or blood was squeezed out after pricking. The treatment was given once a week, for 4 weeks totally. In the medication group, erkangning syrup was administered, 3 times a day, for 4 weeks totally. The ghrelin, leptin and neuropeptide Y (NPY), and the clinical efficacy were observed before and after treatment in each group.</p><p><b>RESULTS</b>The levels of ghrelin and NPY before treatment in acupuncture group and the medication group were lower apparently than those in the healthy control group (all P < 0.01), but the level of leptin was higher appa-rently than that in the healthy control group (P < 0.01). After treatment, the levels of ghrelin and NPY were higher apparently than those before treatment in the acupuncture group (both P < 0.01), and the level of leptin was lower apparently than that before treatment (P < 0.01). All of the above indices in the acupuncture group were improved obviously after treatment as compared with those in the medication group (all P < 0.01). The remarkable and effective rate were 82.5% (33/40) and 32.5% (13/40) and the total effective rate were 95.0% (38/40) and 45.0% (18/40) in the acupuncture group and medication group separately, the results in the acupuncture group were superior to the medication group (both P < 0.01).</p><p><b>CONCLUSION</b>Acupuncture at Sifeng (EX-UE 10) effectively promotes the secretion of ghrelin and NPY and inhibit leptin. It effectively promotes appetite for the children and the efficacy is superior to erkangning syrup.</p>

Effect of curcumin on pulmonary hypertension and wall collagen of pulmonary arterioles of chronic hypoxic hypercapnic rats / 中国应用生理学杂志

<p><b>AIM</b>To study the effect of curcumin on pulmonary arterial pressure and type I collagen of pulmonary arterioles in pulmonary hypertensive rats induced by chronic hypoxia and hypercapnia.</p><p><b>METHODS</b>Thirty six rats were randomly divided into three groups: normal control group (NC), hypoxic hypercapnic group (HH) and hypoxic hypercapnia + curcumin group (HC). Collagen I in pulmonary arterioles was observed by the technique of immunohistochemistry.</p><p><b>RESULTS</b>(1) The findings from hemodynamics showed that the mPAP in group HH was significantly higher than that in group NC and HC. Differences of mCAP among groups were not significant (P > 0.05). (2) Light microscopy showed the value of WA/TA (vessel wall area/total area), SMC (the density of medial smooth muscle cells) and thickness of pulmonary arterial media smooth cell layer(PAMT) were significantly higher in group HH than group NC (P < 0.01) and group HC (P < 0.01). (3) Electron microscopy showed that structure of the endothelial cells in pulmonary arterioles in group HC was near to normal, and the proliferation of medial smooth muscle cells and collagen fibers in adventitia was much lighter than those of group HH. (4) Expression of collagen I in pulmonary arterioles was significantly higher in group HH than group NC (P < 0.01) and group HC (P < 0.01).</p><p><b>CONCLUSION</b>Curcumin can decrease pulmonary arterial pressure, improve pulmonary vessel remodeling and inhibit the deposition of collagen I in pulmonary arterioles.</p>
