OBJECTIVETo compare the difference in clinical efficacy on polycystic ovary syndrome (PCOS) between electroacupuncture (EA) and dyne-35 and to explore the effect mechanism.

METHODSSixty-five patients were randomized into an EA group (33 cases) and a western medication group (32 cases). In the EA group, the selected acupoints were Danzhong (CV 17), Qimen (LR 14), Zhongwan (CV 12), Tianshu (ST 25), Guanyuan (CV 4), Zigong (EX-CA 1), Sanyinjiao (SP 6), Zusanli (ST 36) and Taichong (LR 3), etc. After the arrival of qi, electric stimulation was attached to the acupoints for 30 min. The treatment was given 3 times a week. In the western medication group, dyne-35 was prescribed on the 5th day of natural menstruation or withdrawal bleeding, one tablet a day, continuously for 21 days. The treatment cycle was 3 months in the two groups. The menstrual condition, body mass, body mass index (BMI), serum testosterone (T), luteinizing hormone (LH), follicle-stimulating hormone (FSH) and LH/FSH were compared before and after treatment in the two groups. The clinical efficacy was assessed in the two groups.

RESULTSThe total effective rate was 90.6% (29/32) in the EA group and was 93.3% (28/30) in the western medication group. The efficacy was similar in the two groups (P > 0.05). After treatment, the levels of LH and LH/FSH were all reduced significantly in the two groups (all P < 0.01). After treatment, T level in serum was reduced apparently in the western medication group (P < 0.05). Before and after treatment, the differences in body mass and BMI in the EA group were more significant than those in the western medication group (P < 0.01, P < 0.05).

CONCLUSIONEA is the effective method for PCOS, similar to that of dyne-35. The effect of it for weight loss is superior to dyne-35 and no apparent adverse reactions happen. The effect mechanism of EA is related to the regulation of serum sexual hormone levels and their ratio, as well as to the regulation of body lipid metabolism.

BACKGROUND: Few studies have reported the effect of aldosterone receptor antagonist (ARA) on myocardial remodeling after acute myocardial infarction (AMI). This study was undertaken to investigate the preventive effect of ARA on myocardial remodeling after AMI.METHODS: A total of 616 patients who had been admitted into the CCU of the First Affiliated Hospital of Harbin Medical University from January 2008 to January 2010 were studied prospectively. Only 528 patients were observed completely, including 266 of the control group and 262 of the treatment group. There was no statistical difference in age, gender, medical history, admission situation, and treatment between the two groups (P>0.05). The preventive effects of spironolactone on cardiac remodeling, left ventricular function, renal function and blood levels of potassium were evaluated by echocardiography, serum potassium and serum creatinine at one-month and one-year follow-up.RESULTS: The echocardiography indicators such as LVESD, LVEDD, LVEF, LAD-ML and LAD-SI were signifi cantly improved in the treatment group compared with the control group at one year (P<0.05). In the treatment group, LVESD, LVEDD, LVPWT, LVEF, LAD-ML and LAD-SI were more significantly improved at one year than one month (P<0.05,P=0.007 to LVEF), and in the control group LVEF was more signifi cantly improved at one year than one month (P=0.0277). There were no signifi cant differences in serum potassium and serum creatinine levels between the two groups.CONCLUSION: On the basis of conventional treatment, the early combination of low-dose spironolactone (20 mg/d) could inhibit cardiac remodeling at late stage and prevent heart failure.

A series of adefovir mono-L-amino acid esters, mono non-steroidal anti-inflammatory drugs carboxylic ester prodrugs with more potent anti-HBV activity and lower nephrotoxicity were designed and synthesized. Adefovir bis (L-amino acid) ester was used as lead compound, according to pathological and pharmacological findings that non-steroidal anti-inflammatory drugs can effectively inhibit the organic anion transporter 1 (hOAT1)-mediated adefovir phosphonic acid pairs of anion transport across tubular basement membrane thereby reducing the nephrotoxicity of adefovir. Flatten design principle was used to introducing non-steroidal anti-inflammatory drugs structural fragments to design and synthesize target adefovir mixture ester prodrugs. HepG2 2.2.15 cell line was used as in vitro anti-HBV activity evaluation model. Five compounds exhibited antiviral activity, and compound 18 showed the most potent anti-HBV activity and relatively high selective index (EC50 3.92 micromol L(-1), SI 9.97). HK-2 cell line was used as in vitro model to evaluate nephrotoxicity. Results suggested the target compounds have lower cytotoxicity than the positive control. Moreover, by analyzing the primary structure and activity relationship of these compounds, it could suggest that mono-L-amino acid ester, mono non-steroidal anti-inflammatory drugs carboxylic ester prodrugs strategy has significant potential in the acyclic nucleoside phosphonates prodrug design.

OBJECTIVETo observe the effect of Chuanhuang No.1 Recipe (CHR) on renal function and micro-inflammation in phase 3 chronic kidney disease (CKD) patients.

METHODSTotally 60 phase 3 CKD patients were randomly assigned to the treatment group (treated by CHR) and the control group (treated by Losartan Potassium), 30 in each group. All patients received basic treatment. Patients in the treatment group took CHR decoction, 400 mL each time, one dose per day, while those in the control group took Losartan Potassium, 50-100 mg per day. All medication lasted for 24 weeks. Changes of serum creatinine (SCr), blood urea nitrogen (BUN), estimated glomerular filtration rate (eGFR), serum uric acid (UA), 24 h urinary protein excretion (24 h U-pro), urinary microalbumin (U-Alb), high-sensitivity C-reactive protein (hs-CRP), serum tumor necrosis factor (TNF)-alpha, and serum IL-6 were detected and compared before and after treatment. Efficacy was also compared.

RESULTSCompared with before treatment, SCr and BUN significantly decreased in the treatment group (P<0.05, P<0.01); eGFR in- creased (P<0.05). Only UA obviously decreased in the control group (P<0.05), but with no obvious change in SCr, BUN, or eGFR. Compared with before treatment, 24 h U-pro decreased after treatment in the treatment group (P<0.05), but with less decreased level when compared with the control group. U- Alb was also significantly decreased in the control group (P<0.01). There was statistical difference in 24 h U-pro and U-Alb between the two groups after treatment (P<0.05). Compared with before treatment, hs-CRP obviously decreased after treatment in the two groups, but serum levels of TNF-alpha and IL-6 obviously decreased only in the treatment group (P<0.05). The total effective rate was obviously higher in the treatment group than in the control group (70.00% vs. 43.33%, P<0.01).

CONCLUSIONCHR could efficiently improve the renal function of phase 3 CKD patients and alleviate the micro-inflammation.

Objective To investigate the effects of endogenous and exogenous hydrogen sulfide (H2S) on the KATP current in isolated rat ventricular myoeytes. Methods Ventrieular myoeytes were isolated from rat heart by modified Langendoff perfusion with collagenase. KATP current of single rat ventricular myocytes was recorded by whole-cell patch-clamp technique. Results The density of KATP current was significantly reduced by 200 μmol/L DL-propargylglyeine (PPG, an irreversible inhibitor of the H2S) [(5.3258±0.7556) pA/pF vs. (3.7856±0.4312) pA/pF, P ＜ 0.01] in a time-dependent way. The density of KATP current could be significantly increased by NariS(a H2S donor, 9.375, 18.75, 37.5,75, 150 μmol/L) in a concentration-dependent manner [(6.6310±0.6092) pA/pF vs. (9.0949±1.0259)pA/pF at 150 μmol/L, P ＜ 0.01]. Conclusion Both endogenous and exogenous H2S could open KATP channels and enhance the KATP current in rat ventricular myocytes.

OBJECTIVETo investigate the dynamic variability of intestinal flora and endotoxins in rats with fulminate hepatic failure.

METHODSEstablishing the fulminate hepatic failure models by intraperitoneal injection of Galactosamine. Forty Sprague-Dawley rats were divided into three groups: group A (n=10) were killed at the beginning of the experiment as control; while Group B (n=12) and C (n=18), the fulminate hepatic failure models, were killed 24 and 48 hours respectively after successful induction. Then, the contents of the jejunum, ileum and colon descendents were collected and a quantitative analysis was made about intestinal flora. Meanwhile, the concentrations of endotoxin in portal vein and right ventricle were determined and so were those in contents of ileums and colons.

RESULTSOur experiments showed that the livers of rats in group B were injured most seriously among three groups, and a minor recovery of hepatic function was observed in group C with the decrease of total bile acids (P< 0.05). Analysis on intestinal flora show: the intestinal enterobacteriacea increase and the lactobacillus decrease in group B (P< 0.01 in jejunum and ileum and P<0.05 in colon). The comparisons between group C and B showed that the enterobacteriacea in the former decreased in both jejunum and colon (P< 0.05) while the number of lactobacillus recovered in the jejunum of group C (P<0.05). Quantitative analysis on endotoxins showed that the ileum endotoxin increased in group B (P< 0.05) and in group C, endotoxins in ileum and colons also increased (vs. control, P<0.01); portal endotoxin in group B showed higher level than that in group A and C (P< 0.01).

CONCLUSIONThe alteration of intestinal flora was observed in fulminate hepatic failure rats. Abnormal intestinal flora might lead to incline of endotoxin in ileum, colon and portal vein, while the recovery of normal intestinal flora would decrease the level of portal endotoxin.
