Objective To compare the safety and efficacy of whole stage and first stage of labor analgesia on puerperas with pregnancy-induced hypertension syndrome.Methods From March, 201 5 to November,201 5,1 96 single fetus,aged 22-35 years,term pregnancy,primipara,ASA physical status Ⅰ or Ⅱ, diagnosed pregnancy-induced hypertension syndrome, were randomly divided into the whole stage of labor analgesia group (group T)and the first stage of labor analgesia group (group F).Patients in group T received labor analgesia after uterine contractions regularly,and continued the labor analgesia to the end of the delivery;patients in group F received labor analgesia after uterine contractions regularly and the uterus cervix was 3 cm,in the end of the first stage of la-bor,using the normal saline instead of the medicine.The MAP and VAS score were recorded before analgesia and 10 minutes,60 minutes after the beginning of analgesia,when the uterine cervix dilated absolutely,the second stage of labor and when the fetal is delivered.The Bromage scores were recor-ded at the second stage of labor.The time for the first stage of labor,the second stage of labor and the third stage of labor were recorded.The mode of delivery,the incidence of eclampsia,postpartum hemorrhage,the use of oxytocin and antihypertensive in the delivery progress were recorded.The ne-onate weight,Apgar score and the cord blood gas analysis were recorded.Results At the uterine cer-vix dilated absolutely and the second stage of labor,the MAP [(106.0±7.0)mm Hg vs.(1 1 5.4± 7.3)mm Hg,(106.2 ± 7.2 )mm Hg vs.(1 1 6.0 ± 7.6 )mm Hg]and VAS score [(2.0 ± 1.1 ) scores vs.(5.1±1.2)scores,(1.9±1.2)scores vs.(5.2±1.3)scores]in group T were lower than those in group F (P <0.05).The patients who received oxytocin in group T were more than that in group F [50(5 1%)vs.35(35%),P <0.05].Conclusion The whole stage labor epidural analgesia is safe and effective for puerperas with pregnancy-induced hypertension syndrome.

OBJECTIVE: The objective of this study was to identify the risk factors for central lymph node metastasis (CLNM) of papillary thyroid microcarcinoma(PTMC) and to explore the necessity of central lymph node dissection (CLND). METHOD: Clinical data of 85 patients with PTMC, who had undergone surgical treatment between January 2004 and May 2012, were retrospected. Risk factors for CLNM were identified by univariate analysis and multivariate analysis,which can provide the basis for elective performance of CLND. RESULT: Of 85 patients,66 patients underwent ipsilateral CLND,while 19 patients received bilateral CLND. Concurrent cervical lymph node dissection was performed in 3 patients. The incidence of central and cervical lymph node metastasis was 38.8% and 3.53%, respectively. Univariate analysis showed that CLNM was correlated with tumor size > 5 mm, extrathyroidal extension, multifocality, bilaterality and intraoperatively suspected lymph node, but not related to gender and age. Upon multivariate analysis, tumor size > 5 mm (OR = 3.862, P < 0.05) and extrathyroidal extension (OR = 3.885, P < 0.05) were independent risk factors for CLNM. CONCLUSION Patients presenting tumor size > 5 mm and/or extrathyroidal extension may have an increased risk of central lymph node metastasis,and it is necessary to perform central lymph node dissection for them.

Objective To compare the continuous subarachnoid block with ropivacaine or sufen?tanil either alone or in combination for labor analgesia. Methods Ninety nulliparous parturients who re?quired labor analgesia voluntarily, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, aged 23-35 yr, with a body height of 155-170 cm, were included in this study. When regular uterine contrac?tion appeared, labor analgesia was performed in the first stage of labor. The parturients were divided into 3 groups ( n=30 each ) using a random number table: ropivacaine group ( group R ) , sufentanil group (group S), and combination of ropivacaine and sufentanil group ( group RS). The spinal catheter was placed at L3,4 interspace. In group R, ropivacaine was given as an initial bolus of (0.6 mg∕ml) 5 ml fol?lowed by an infusion of 0.2 mg∕ml after the analgesia pump was connected. In group S, sufentanil was given as an initial bolus of (1.6 μg∕ml) 5 ml followed by an infusion of 0.2μg∕ml after the analgesia pump was connected. In group RS, the mixture of ropivacaine 0. 3 mg∕ml plus sufentanil 0. 8 μg∕ml was given as an initial bolus of 5 ml, followed by an infusion of the mixture of ropivacaine 0. 1 mg∕ml plus sufentanil 0.1 μg∕ml after the analgesia pump was connected. The analgesia pump was programmed to deliver a 5 ml bolus dose with a 15 min lockout interval, background infusion at a rate of 5 ml∕h, and the total volume of 100 ml in the three groups. The analgesia pump was connected at 30 min after the initial bolus was given, and the infusion was stopped at 2 h after delivery in the three groups. Visual analog scale ( VAS) scores were maintained ≤3. VAS scores were recorded before analgesia and at 5, 10 and 30 min after the initial bolus was given. The interval and duration of uterine contraction were recorded before analgesia, in 0-30 min, 30-60 min and 90-120 min of analgesia periods, and in the second stage of labor. The development of nausea and vomiting, pruritus, lateral episiotomy, assisted vaginal delivery, cesarean section, and post?dural puncture headache and requirement for oxytocin were recorded. Apgar scores at 1, 5 and 10 min after birth were recorded. Results The Apgar score of the newborn was more than or equal to 7 at 1, 5 and 10 min after birth in the three groups. Compared with the value before analgesia, the interval of uterine contraction was significantly prolonged, and the duration of uterine contraction was significantly shortened in the 0-30 min of analgesia period in group R ( P<0.05) , and no significant change was found in the inter?val and duration of uterine contraction in each analgesia period in S and RS groups ( P>0.05) . Compared with group R, the VAS scores were significantly increased at 5 and 10 min after the initial bolus was given, the interval of uterine contraction was significantly shortened, and the duration of uterine contraction was significantly prolonged in S and RS groups, and the incidence of pruritus was significantly decreased in group S ( P<0.05 or 0.01) . Compared with group S, the incidence of pruritus was significantly decreased ( P<0.01) , and no significant change was found in the VAS scores at each time point and interval and du?ration of uterine contraction in each analgesia period in group RS ( P>0.05) . Conclusion Continuous sub?arachnoid block with combination of ropivacaine and sufentanil provides better efficacy for labor analgesia than ei?ther alone.

Objective To assess the clinical outcomes of posterior decompression and lumbar interbody fusion with internal fixation treatment for degenerative lumbar scoliosis (DLS). Methods Ninety-eight patients underwent surgery for DLS were retrospectively reviewed in this study. The mean age of the patients(male 35 and femail 63) was (56±9) years. The mean Cobb angle of curves was (26±9)° and the mean scoliosis Cobb angle of lumbar was (19±11)° in patients before surgery. A posterior medial incision was made for spinal exposure. According to the preoperative plan, patients were operated with posterior de-compression and lumbar interbody fusion with internal fixation. The clinical outcomes were assessed by the JOA scores.The preoperative and postoperative Cobb angle was recorded. Results The mean follow-up time was (3.7±2.4) years. The mean JOA scores were improved from (10±2) points preoperatively to (26±3) points at the last follow-up. The excellent or good outcome rates were 89.7%for patients with surgery. The average interbody fusion time was (5.7±1.4) months. The mean postoperative Cobb angle was (6±2)° at the last follow-up, and the mean Cobb angle correction was (17±4)°, with the correction rate of 59.2%. The mean lumbar lordosis angle was (12±3)°. There was no failure in internal fixation. Conclusion The posterior decompression and lumbar interbody fusion with internal fixation appears to be a reasonable option for degenerative lumbar scoliosis.

Objective To investigate the clinical therapeutic effect of Xuebijing injection for treatment of patients with diabetic nephropathy(DN)and its mechanism. Methods 60 DN patients were randomly divided into Xuebijing group and control group(each,30 cases). The patients in both groups received western conventional treatment,and the patients in Xuebijing group received additionally Xuebijing injection intra-venous injection once a day for 14 days. The fasting blood glucose(FBG),glycosylated hemoglobin(HbA1c),urinary albumin excretion rate(AER),blood urea nitrogen(BUN),serum creatinine(SCr),hematocrit(HCT),fibrinogen(Fg),whole blood viscosity,total cholesterol(TC),triglyceride(TG),low density lipoprotein cholesterol(LDL-C),high density lipoprotein cholesterol(HDL-C)and interleukin -6(IL-6),tumor necrosis factor-α(TNF-α)and urine β2-microglobulin(β2-MG)levels before and after treatment were detected,and the curative effect was also observed in both groups. Results In the control group blood FBG,BUN,SCr,TC,IL-6 and TNF-αafter treatment were significantly decreased and HDL-C significantly increased compared with those before treatment(all P<0.05). Compared with those before treatment,in Xuebijing group after Xuebijing therapy,blood FBG,β2-MG,AER,BUN, SCr,TC,TG,HCT,blood viscosity,IL-6 and TNF-αwere significantly decreased,and HDL-C was obviously increased,but there were no significant differences in HbA1c,LDL-C and Fg before and after treatment. The above indexes were changed significantly in Xuebijing group compared with those in control group〔FBG(μg/L):6.98±1.14 vs. 9.73±1.62,β2-MG(μg/L):32.1±10.9 vs. 57.2±15.1,AER(μg/min):86.0±28.1 vs. 152.0±51.6,BUN (mmol/L):12.4±8.1 vs. 19.5±8.9,SCr(μmol/L):301.2±151.9 vs. 371.3±168.6,HCT:0.283±0.075 vs. 0.351±0.059,TC(mmol/L):3.4±1.8 vs. 4.1±1.5,TG(mmol/L):3.4±1.5 vs. 3.6±1.7,HDL-C(mmol/L):1.90±0.75 vs. 1.50±0.25, IL-6 (ng/L):8.96±2.07 vs. 12.75±2.47, TNF-α(pmol/L):17.85±4.75 vs. 20.87±4.90,P<0.05 or P<0.01〕. The total efficiency in Xuebijing group was significantly higher than that in control group(83.3%vs. 36.7%,P<0.01). Conclusion Xuebijing injection has significant protective effects on patients with DN,and the mechanism might be associated with increasing tissue perfusion and inhibiting excessive inflammatory cytokines release.

A total of 40 patients with COPD (excluding those with correlated/relevant diseases)were measured for inflammation parameters of erythrocyte sedimentation rate (ESR) and c-reactive protein (CRP) after hospital admission and some coagulation/fibrinolysis parameters including D-dimer,thrombinantithrombin (TAT),prothrombin fragment 1 + 2,(tissue plasminogen activator) tPA,plasminogen activator inhibitor 1 (PAI-1),von Willebrand factor (von WF),endothelin receptor A,thromboxane B2,P-selectin and pulmonary arterial pressure (PAP) by ultrasonic cardiography after the settling of the symptons of acute period.All patients were then divided into 2 groups according to PAP [＜ 40 mm Hg (1 mmHg=0.133 kPa) (n=24),＞40 mm Hg (n=16)].The values of CRP and ESRin the group with PAP ＞ 40 mm Hg were significantly higher than those in another group (P =0.044 and P =0.002respectively) while tPA was lower (P =0.04).A moderate positive correlation existed between tPA and TXB2 (r =0.547).Moreover,a highly positive correlation was found between TXB2 and PAl-1 (r =0.929).The results indicated that the COPD patients with pulmonary arterial hypertension (PAH) tend to have a higher level of inflammation,and their fibrinolysis becomes impaired leading to a prothrombotic state.

Objective To build the cohort of drug resistance and analyze treatment efficiency of AIDS patients and situation of drug resistant mutations among HIV-1 infected individuals.Methods A cohort of 116 HIV-1 infected patients was built and their treatment progress were acquired once every 6 months.At the sanle time CD4+ T cell counts and HIV-1 viral load were measured and genotyping for drug resistance was determined by a home brew nested PCR.Results The CD4+ T cell count(470±251/ml)was higher than that before treatment in patients who were treated by AZT/DDI/NVP or D4T/DDL/NVP.The viral load was lower than that before treatmenL The drug resistant mutation frequency increased gradually along with treatment.The CD4+ T cell count was decreased and viral load was increased and the prevalence of drug resistant mutation was increased in the patients who changed regimens to AZT/3TC/NVP or D41/3TC/NVP.Only one primary mutation that was resistant to non-nucleoside reverse transcriptase inhibitors (NNRTIs)was detected in the naive patients.The cross-resistant mutation was detected in two patients after 6 months treatment. The intermediate resistance to lopinavir(LPV) was detected after 12 months treatment.The prevalence of high-grade resistances to NNRTIs was increased obviously,and the prevalence of multi-resistance and cross-resistance was detected in 5 patients after 36 months treatment.Conclusions The prevalence of primary mutation was rare in naive HIV-1 infected patients.The prevalence of drug resistant mutation was inereased gradually along with treatment.Ahhough few regimens were available,the treatment effect could last relatively long period of time if patients keep taking medicine stably.The regimens could be changed according to the results of drug resistant test.

Objective:To investigate the effectiveness of irbesartan in combination with ramipril for treatment of chronic heart failure in patients with rheumatic heart disease(RHD).Methods:A total of 120 RHD patients with chronic heart failure were randomized into treatment group(n=60)and control group(n=60)after valve replacement.All patients received regular ramipril treatment(5 mg/d);treatment group were also given irbesartan(150 mg/d).The patients were followed up for 6 months.The indices of observation included cardiac function(NYHA Class),6-Minute Hall Walk distance,and echocardiographie parameters.Results:Six months later the cardiac function in the treatment group was obviously improved compared with the control group;the patients in the treatment group had significant increase in 6-Minute Hall-Walk distance and improvement in echocardiographic parameters(left ventricle end-systolic diameters,end-diastolic diameter,ejection fraction, fractional shortening,P
