Objective To investigate the efficacy of laparoscopy for the treatment of rectovaginal septum endometriosis. Methods A totalof 13 patients with rectovaginal septum endometriosis underwent open (5 cases) or laparoscopic (8 cases) operations in our hospital between January 2001 and May 2006.Results In the open surgery group,the operation time ranged from 130 to 200 minutes (mean,187 minutes) ,and the mean intraoperative blood loss was 189 ml (170 to 280).After the operation,the menstrual pain was relieved in 5 cases at 1 month,4 at 3 months,3 at 6 months,and 2 at 12 months.Whereas,in the laparoscopy group,the operation time ranged from 120 to 185 minutes (mean,155 minutes),and the mean blood loss was 135 ml(100 to 190 ml).The menstrual pain was relieved in 8 cases at month 1,8 cases at month 3,7 cases at month 6,and 5 cases at month 12.Conclusions Laparoscopic surgery is effective and safe for patients with rectovaginal septum endometriosis.

Objective To evaluate the effects of nimodipine (NIM) on pregnancy induced hypertension(PIH) and to assesse the effects of nimodipine on intraplatelet free calcium(PF[Ca 2+ ] i). Methods Fourty eight patients with moderate or severe PIH were randomized to receive either NIM or magnesium sulfate. We observed the change of blood pressure, urc protein, PF[Ca 2+ ] i and symptoms of preeclampsia before and after medication. We compared the pregnancy outcome of the two groups. Results 1.There was significant reduction of blood pressure at 1/2 h?1 h and 2 h after the administration of nimodipine. The maternal heart rate increased significantly ( P

AIM: To explore the mechanism of nicotine against the apoptosis induced by colchicines in rat cortical neurons.METHODS: Cortical neurons were cultured from newborn Sprague-Dawley(SD) rats(less than 12 h).The rate of apoptosis was measured by Hoechst33258 fluorescence staining in the neurons,and the activity of Akt473 was analyzed by assay kit Akt473.RESULTS: The apoptosis of cortical neurons can be induced by 0.1 ?mol/L colchicine.The phosphorlation of Akt 473 decreased significantly(1/3 times of the control group,P

Objective: The extract technologies for the components of Fuzhuang Capsules were optimized. Methods: Four methods: the semi bionic extraction (SBE), the water extraction (WE), the semi bionic extraction by precipitation with alcohol (SBAE) and the water extraction by precipitation with alcohol (WAE) were used to extract Fuzhuang Capsules, with panaxadiol, panaxatriol, ? sitosterol, icariine, betaine, total sugar and dried extractive taken as the marker, under the same conditions of drug granularity, solvent amount, decocting temperature, filtration, concentration, etc., and then four methods were compared and studied. Results: Through the comprehensive evaluation of seven markers, their comprehensive values Y decreased in the order of SBE, WE, SBAE and WAE. Conclusion: SBE is better than the other three methods in the extraction of the components of Fuzhuang Capsules, which is showed by the fact that the pH values of the water for the 1st, 2nd and 3rd decoctions are 3.4, 7.5 and 8.4, and the extraction times are 2.0h, 1.5h, and 1.5h respectively.

AIM: To observe the effect of Huangqi Danggui Mixture on diabetic nephropathy. METHODS: Using Huangqi Danggui Mixture to treat 32 patients with diabetic nephropathy,In control group 22 patients were treated with Losartan.The therapeutic course was 3 months for both groups.The changes of clinical symptoms,blood glucose,lipid metabolism and urinary albumin were observed and compared. RESULTS: The total effective rate in the treated group was 80.9% while in the control group 63.3%.The symptoms,urinary protein and albumin as well as lipid metabolism in the treated group all significantly improved after treatment (P

Objective:To evaluate right heart remodeling and right heart function change after pulmonary resection by echocardiography (ECG) .Methods:A total of 50 patients undergoing pneumonectomy received ECG examination to evaluate right ventricular structure and right heart function change before and after partial pulmonary resection .Re-sults:(1) Compared with before operation , there were no significant changes in right ventricular anterior free wall thickness ,right ventricular ejection fraction on 7d and 30d after operation;(2) Compared with before treatment , there were significant rise in pulmonary artery systolic pressure [PASP ,(20.52 ± 2.46) mmHg vs .(49.65 ± 2.17) mmHg] ,pulmonary artery diastolic pressure [PADP ,(10.82 ± 2.04) mmHg vs .(21.93 ± 1.26) mmHg] and pul-monary artery mean pressure [PAMP ,(13.78 ± 3.67) mmHg vs .(26.67 ± 3.28) mmHg] ,and significant rise in pulmonary vascular resistance [PVR ,(187.69 ± 12.46) dyn .s .cm-1 vs .(368.72 ± 11.94) dyn .s .cm-1 ] on 7d after pulmonary resection , P<0.05 all;all above indexes recovered to normal on 30d after treatment ;(3) Com-pared with before operation ,right ventricular Tei index significantly rose [ (0.36 ± 0.05) vs .(0.69 ± 0.13) , P=0.04] on 7d after operation ,the Tei index recovered to normal on 30d after treatment ,P=0.20. Conclusion:Com-pared with before operation , the PASP ,PADP and PAMP significantly rise on 7d after operation ,they recover to normal on 30d after treatment ;there are no significant change in right ventricular structure .

In this study,a series of new sildenafil analogues 11-27 possessing a guanidine group were synthesized to investigate their PDE5 inhibitory activity and selectivity using[~3H]cGMP SPA kit in vitro and efficacy in the rat model of erection.Most of the compounds showed potent activity against PDE5,and more importantly,several compounds exhibited higher PDE5 selectivity over PDE6 than that of sildenafil.Structure-activity relationship of these sildenafil analogues was also discussed.Within this series of compounds,compound 15(IC_(50) =1.7 nmol/L)not only exhibited more potent PDE5 inhibitory activity than that of sildenafil (IC_(50) = 6.5 nmol/L),but also showed functional efficacy in the rat model of erection.

A CdTe/ZnSe quantum-dot submicrobead ( QBs ) , which exhibited fluorescence intensity approximately 2800-fold stronger than that of single quantum dots, was conjugated with the anti-histidine rich protein( HRP )-Ⅱ mAbs using N-( 3-( Dimethylamino ) propyl )-N'-ethylcarbodiimide hydrochloride ( EDC ) method as fluorescence probe. The goat anti-HRP-Ⅱ polyclonal antibodies and donkey anti-mouse polyclonal antibodies were sprayed onto the nitrocellulose membrane as test line and control line, respectively. The resultant fluorescence probes were introduced to the immunochromatographic strip for the quantitative determination of Plasmodium falciparum. For determination of Plasmodium falciparum in serum, the QBs based immunochromatographic strips exhibited a good dynamic linear range from 5 . 8 Parasite/μL to 8010 Parasite/μL with a limit of detection of 5. 8 Parasite/μL. The detection time of the proposed QBs based immunochromatographic strips for each sample was only 15 min. Moreover, the recovery rates of the intra-and inter-assay ranged from 93. 0% to 111. 9%, and 98. 3% to 115. 1% respectively, while the relative standard deviations ( RSDs) of intra-and inter-assay were below 5%.
