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 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 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.

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 evaluate the predictive value of modified early warning score (MEWS) and SMART-COP score on mechanical ventilation in patients with severe influenza A H1N1. Methods Fifty cases diagnosed with severe influenza A H1N1 were retrospectively analyzed. The MEWS and SMART-COP score were calculated. The area under the receiver operating characteristic (ROC) curve (AUC) was evaluated using ROC curve. MEWS, SMART-COP score and AUC were analyzed by Z test. Results The AUCs of MEWS and SMART-COP score for predicting mechanical ventilation were 0. 923 and 0. 889, respectively, which were not significantly different (Z=0. 548, P =0. 584).Conclusion Both of MEWS and SMART-COP score are predictive factors of mechanical ventilation in the patients with severe influenza A H1N1.

BACKGROUND: Many studies have suggested that angiotensin-converting enzyme inhibitors(ACEI) protect blood vessels through anti-atherosclerosis independent of lowering blood pressure, but its mechanism is still unclear.OBJECTIVE: To investigate the anti-atherosclerotic mechanism of ACEI by observing the effects of Enalapril on lipoprotein(a) and oxygen free radicals in patients with acute myocardial infarction (AMI) .DESIGN: A controlled study based on the observation of the patients with AMI.SETTING: Second Department of the South Building, General Hospital of Chinese PLAPARTICIPANTS: Thirty-five inpatients with AMI(19 males and 16 females, aged 42 -75 years old, and averaged (62 ± 9) years old and hospitalized at the Department of Cardiology of Tianjin Harbor Hospital from April 2001 to August 2002 were chosen. These patients were randomly divided into 2 groups: the therapeutic group(20 cases) and the control group(15cases). Inclusion criteria: the diagnosis of patients with AMI was confirmed by WHO criteria. Exclusion criteria: patients with renal dysfunction, shock,hypotension, a history of allergy to ACEI, and a history of severe cough induced by ACEI. All patients had not taken ACEI in the past 2 weeks and agreed to participate in this study.METHODS: On early morning of the third day after AMI, patients in the treatment group took 5 mg of Enalapril one time. If they had no first-dose reaction of hypotension, on the fourth day after AMI, the patients of the treatment group were given a dose of 5 mg twice per day for the following 2 weeks. Then, they were given the drug at a dose of 10 mg twice per day for 2 weeks. The patients in the control group were not given Enalapril. Blood samples were taken respectvely prior to the administration and 2 weeks and 4 weeks after the administration in the two groups. Serum content of lipoprotein(a), oxygen free radicals, triglyceride, total cholesterol, high density lipoprotein(HDL) cholesterol, Apo(a) were measured.MAIN OUTCOME MEASURES: We compared the level of serum of lipoprotein (a), oxygen free radicals (OFR), triglyceride, total cholesterol,HDL cholesterol, Apo(a) pre-treatment and post-treatment respectively in patients of the two groups.RESULTS: Serum levels of OFR were significantly lowered in the treatment group, which were(1 423.14±216.23), (1 076.62±287.12) and (566.57 ± 138.02) U/mL respectively 2 weeks and 4 weeks before and after the treatment(t =2. 937, 3. 571, P ＜0. 01), but there were no significant changes in serum concentrations of lipoprotein(a) and lipids( P ＞ 0.05) .CONCLUSION: Enalapril improved the prognosis of patients with AMI by antioxidation, but not by lowering the serum levels of lipoprotein(a) and lipids. The study can serve as a theoretical reference that the mechanism of Enalapril might inhibit atherosclerosis in patients with AMI.
