Observation on therapeutic effect of " acupuncture" on premature ovarian insufficiency of kidney deficiency / 中国针灸

OBJECTIVE@#To observe the clinical efficacy of " acupuncture" and oral estradiol and dydrogesterone tablets (femoston) on premature ovarian insufficiency of kidney deficiency.@*METHODS@#A total of 50 patients with premature ovarian insufficiency of kidney deficiency were randomized into an observation group and a control group, 25 cases in each one.In the observation group, " acupuncture" was applied at Baihui (GV 20), Zhongwan (CV 12), Guanyuan (CV 4), Qihai (CV 6), Zhongji (CV 3), Yaoyangguan (GV 3), Yaoshu (GV 2), Mingmen (GV 4), etc. once every 2 days, 1 month as a course. In the control group, femoston was prescribed for oral administration, one tablet per time, once a day, 1 month as a course. Both of the two groups were given consecutive treatment for 3 courses. Before and after treatment, the clinical symptoms, menstrual improvement as well as the changes of estradiol (E), luteotrophic hormone (LH) and follicle-stimulating hormone (FSH) in serum were observed in the two groups.@*RESULTS@#After treatment, the clinical symptoms and menstrual conditions were improved (<0.01), the levels of FSH and LH were significantly reduced (<0.01), and the levels of E were significantly increased in the two groups (<0.01). There were no significant difference in menstrual improvement rate and menstrual improvement time between the observation group and the control group (<0.05), the recurrence rate of menopause and clinical symptom score improvement in the observation group were superior to the control group (<0.05). In the observation group, the level of E in serum was lower and the levels of FSH and LH in serum were significantly lower than those in the control group (<0.05, <0.01). In the observation group, the rate of adverse reaction was 4.0% (1/25), which was lower than 36.0% (9/25) in the control group (<0.05).@*CONCLUSION@#" acupuncture" has better therapeutic effect for premature ovarian insufficiency of kidney deficiency. It is superior to femoston in improving clinical symptoms and recurrence rate of menopause as well as reducing the levels of FSH and LH.

Effect of Shugan Jianpi Recipe on LXRα/FAS signaling pathway mediated hepatocyte fatty deposits in NAFLD rats / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To explore the effect of Shugan Jianpi Recipe (SJR) on LXRα/FAS signaling pathway mediated hepatocyte fatty deposits in nonalcoholic fatty liver disease (NAFLD) rats.</p><p><b>METHODS</b>Totally 75 SPF grade male SD rats were randomly divided into 5 groups, i.e., the normal control group, the model group, the Shugan Recipe (SR) treatment groups, the Jianpi Recipe (JR) treatment group, and the SJR group. Except rats in the normal control group, the NAFLD rat model was duplicated using high fat diet (HFD). SR (Chaihu Shugan Powder) was administered to rats in the SR group. JR (Shenlin Baizhu Powder) was administered to rats in the JR group. SJR (Chaihu Shugan Powder plus Shenlin Baizhu Powder) was administered to rats in the SJR group. Changes of liver fat were analyzed using automatic biochemical analyzer. Liver cells were separated by low-speed centrifugation. Their activities and purities were identify using Typan blue and flow cytometry (FCM). Expression levels of LXRα and FAS mRNA in hepatocytes detected by Real-time quantitative PCR. Expression levels of LXRα and FAS protein were detected by Western blot.</p><p><b>RESULTS</b>(1) Pathological results showed in the model group, hepatocytes were swollen with nucleus locating at the cell edge after oil red O staining; unequal sized small vacuoles could be seen inside cytoplasm. Some small vacuoles merged big vacuoles. All these indi- cated a NAFLD rat model was successfully established by high fat diet. Pathological structural changes could be impaired to some degree in all medicated groups, especially in the SR group. (2) Compared with the normal control group, expression levels of LXRα and FAS genes and proteins obviously increased in the model group (P < 0.01). Compared with the model group, their expression levels were obviously down-regulated in the JR group and the SR group (P < 0.01, P < 0.05).</p><p><b>CONCLUSIONS</b>LXRα/FAS signaling pathway was an important signaling pathway for mediating lipid metabolism disorders of NAFLD rats. SJR could make hepatocyte fatty deposits tend to repair by adjusting the LXRα/FAS signaling pathway in NAFLD rats, which might be one of important mechanisms for SJR to prevent and cure NAFLD.</p>

Effects of Yuquan pills on pharmacokinetics of metformin hydrochloride in diabetic rats / 中国中药杂志

<p><b>OBJECTIVE</b>To study effects of Yuquan pills on the pharmacokinetics process of metformin hydrochloride in diabetic rats.</p><p><b>METHOD</b>After administration Yuquan pills 7 day to the diabetic rats, the metformin hydrochloride was orally administrated, then the blood samples were collected at different time. The concentrations of metformin hydrochloride in plasma were determined by HPLC method and the pharmacokinetic parameters were calculated.</p><p><b>RESULT</b>The pharmacokinetic parameter Cmax of the controlling group and the testing group were respectively, 18.95, 21.76 mg x L(-1); t1/2 were 1,069.8, 1,767.4 min, respectively; CL/F were 0.013, 0.008 L x min(-1) x kg(-1); AUC were 10,042.1, 10,712.2 mg z L(-1) x min(-1) respectively.</p><p><b>CONCLUSION</b>The pharmacokinetics process of metformin hydrochloride in diabetic rats fits one-compartment model. Yuquan pills has a significant effect on the pharmacokinetics of metformin hydrochloride in diabetic rats.</p>
