Objective To explore operation method,key technique and clinical therapeutic effect of laparoscopy assisted vaginal hysterectomy. Methods Retrospective analysis was conducted on operation method and post operative clinical data of SO cases had LAVH ( LAVH group) , 60 cases had total abdominal hysterectomy (TAH group) and 60 cases had transvaginal hysterectomy ( TVH group), treated from October 2009 to December 2010. Results The blood loss during operation,time to first flatus,incidence of postoperative pyrexia,hospitalization day,time of getting out of bed in LAVH group were (101. 6±6. 2)ml, (22. 9±6. 1 ) min,2% ,0,(5.0 ±1.5)d,(25. 1±5.3)h; the 7 indices in TAH group were (174.0 ±6.9)ml,(35.3±4.3) min,10%,3.3%,(8.5±1.6)d,(56.4±.6.1)h; and the 7 indices in the TVH group were (189.0±8.2) ml, (26.0±8.2)min,6.7%,1.7%,(7.8±3.5)d,(49.4±3. 8) h. The numbers in LAVH group were all lower than those in TAH group and TVH group ( Ps < 0. 05 ). Conclusion LAVH has advantages of less operation blood loss,less injury to body and sooner recovery,less complications compared with TAH and TVH. This is a safe and effective operation type,which is worth of popularizing.

Objective To compare the clinical efficacy between reformed laparoscopic-assisted vaginal hysterectomy with sutureless of cardinal and uterosacral ligament(LAVH)and trans abdominal hysterectomy(TAH)for large uterus.Methods A retrospective study was performed using 106 reformed LAVH patients(observation group)and 100 TAH patients(control group)whose uterus were big(≥ 12weeks of gestation),the information was observed in perioperative period.Results Anal exsufflation time,hospitalization time after operation and postoperative pain time in observation group[(25.4 ± 3.3)h,(6.5 ±1.5)d,(16.9 ± 2.4)h]were significantly shorter than those in control group[(42.4 ± 5.3)h,(8.5 ± 1.5)d,(30.6 ± 5.3)h](P ＜ 0.05),the rate of complication in observation group[5.7％(6/106)]waa lower than that in control group[10.0％(10/100)](P＜ 0.05).Conclusion As to large uterus,reformed LAVH has several advantages over TAH,the technique is easy to learn,operation time is short,and the rate of complication is low.

One hundred and fifty-six patients with primary aldosteronism(PA)and 189 patients with essential hypertension (EH) were included in this study.The value of estimate glomerular filtration rate (eGFR) was calculated by MDRD equation.The plasma levels of aldosterone,triglycerides,creatinine and fasting glucose were measured.The plasma creatine,24 hour urine albumin excretion in PA patients were higher and eGFR and plasma aldosterone were lower than those in EH patients ( all P ＜ 0.01 ).Multiple regression analysis revealed that the plasma concentrations of aldosterone ( P =0.003 ) and creatinine ( P =0.001 ) were independent predictors of eGFR.

Objective To understand the epidemiological characteristics of patients with advanced schistosomiasis in Hunan Province,so as to provide the evidence for formulating the advanced schistosomiasis prevention strategies and measures. Meth-ods The data of advanced schistosomiasis patients were collected and analyzed retrospectively with the cross section research method and description method in Hunan Province,2012. Results There were 5 722 advanced schistosomiasis patients in Hu-nan Province,and among them,4 112 patients were male(71.86%),and 1 610 were female(28.14%). Totally 5 311 patients came from the schistosomiasis endemic areas(92.82%)and 411 patients from non-schistosomiasis endemic areas(7.18%). The prevalence rate of advanced schistosomiasis was 8.46/10 000. The mean age of advanced schistosomiasis patients was 60.30 ± 11.63 years,and the youngest was 17 years old and the oldest 92 years old. In the age composition of advanced schistosomiasis pa-tients,the greatest number of cases was in the 60-70 years age group (32.72%). There were 3 595 cases of ascites type (62.83%),2107 cases of splenomegaly type(36.82%),11 cases of dwarf type(0.16%),and 11 cases of colon proliferation type (0.35%). Conclusion The prevalence rate of advanced schistosomiasis is relatively stable in Hunan Province,and the age of the patients showed an old aging trend. The salvation of advanced schistosomiasis patients in non-endemic areas should be strength-ened.

Objective To observe the clinical efficacy of acupuncture at the nine acupoints on nape in treating vertebrobasilar ischemia (VBI). Methods Totally 100 VBI patients were randomized into a treatment group and a control group, 50 in each group. The treatment group was intervened by acupuncture at Fengfu (GV 16), Fengchi (GB 20), Wangu (GB 12), Tianzhu (BL 10), and Jiaji (EX-B 2, C3);while the control group was by oral administration of Nimodipine tablets. The parameters in Transcranial Doppler (TCD) and Dizziness Assessment Rating Scale (ADRS) were observed before and after intervention, and the clinical efficacies were compared. Results The TCD parameters were significantly changed in the treatment group after intervention (P<0.05). The TCD parameters [Vs (RVA), Vd (BA, LVA), Vm (BA, RVA), PI (BA)] were significantly changed in the control group after intervention (P<0.05). After intervention, there were significant differences in comparing the TCD parameters [Vs (BA, LVA, RVA), Vd (BA, RVA), Vm (BA, LVA), PI (BA)] between the two groups (P<0.05). The DARS average scores were significantly changed in both groups after 7-day treatment (P<0.01). The DARS average scores after the whole intervention were significantly different from that after 7-day treatment in both groups (P<0.01). There were significant differences in comparing the DARS average scores between the two groups after 7-day intervention and after the whole intervention (P<0.01). The recovery-markedly effective rate and total effective rate were respectively 76.0%and 98.0%in the treatment group versus 44.0%and 96.0%in the control group, and there was a significant difference in comparing the recovery-markedly effective rate (P<0.05). Conclusions Acupuncture at the nine nape acupoints is an effective method in treating VBI.

The activity of free radicals in follcular fluid was related to ovarian responsiveness,in vitro fertilization (IVF),and embryo transfer success rate.However,studies analyzing the relationship between the free radical scavenging capacity and embryo quality of infertile women with polycystic ovarian syndrome (PCOS) were lacking.The aim of this study was to evaluate the relationship between the free radical scavenging window of women with PCOS and their embryo quality.The free radical scavenging capacity of follicular fluid from women with PCOS was determined by a,a-diphenyl-b-picrylhydrazyl (DPPH),2,2-azinobis (3-ethylbenzthiazoline-6-sulphonic acid) assay,superoxide radical,and reactive oxygen species (ROS) assay.In the DPPH and ROS assays,the follicular fluid from grades Ⅰ and Ⅱ embryos was significantly higher than the follicular fluid from grades Ⅲ and Ⅳ embryos.The lower control limit of DPPH radical scavenging capacity and upper control limit of ROS level were 13.2％ and 109.0 cps,respectively.The calculated lower control limit and upper control limit were further confirmed in the follicular fluid of embryos of all grades.These cut-off values of free radical scavenging activity of follicular fluid could assist embryologists in choosing the development of embryos in PCOS patients undergoing.

The Doppler blood flow signal is inherently a nonstationary Gaussian random process whose time-frequency representation associates with the time-varying velocity of blood flow and its variations. With the assumption that the signal being analyzed is stationary during a short time interval, we can not get Doppler time-frequency representations with satisfactory time and frequency resolution. AR modeling based on Levinson-Durbin algorithm has been used to generate time-frequency representations of Doppler blood flow signals. But the errors of the parameters computed by the algorithm will be aggrandized by the shortening of the time interval. Burg has advanced an algorithm, which computes the parameters by making the sum of forward and backward forecasting errors minimum. In the paper, time-frequency representations computed by Burg and Levinson-Durbin algorithm were compared with the theoretical representation. We found that the time-frequency representations computed by Burg algorithm are more similar to the theoretical representation, especially in frequency band.
