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:
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 observe the influence of transcutaneous CO2emission (TCE) at points on the meridian or beside the meridian after different stimulations like acupuncture De-qi, sham acupuncture, study the correlation between acupuncture De-qi and local energy metabolism through TCE. Methods: Twenty healthy volunteers (male 8, female 12, average age 29 years old) were selected. Before, during and after five different acupuncture Neignan (PC 6), the TCE was measured at Quze (PC 3), point A [at the lower one fourth of line between Tianquan (PC 2) and Quze (PC 3)], point B [at the middle of line between Ximen (PC 4) and Quze (PC 3)], point C (2 cm ulnar side point A) and point D (2 cm ulnar side point B) with a high sensitive C02 instrument (Frewil-Q.F., made in China). The measure results were compared. Results: The comparison on value of TCE before and after the acupuncture, in Sham acupuncture and shallow acupuncture groups, it increased in all five points; in De-qi acupuncture group, there are significant increase on point A, point B, and Quze (PC 3), it has statistic significance, but there are no significant increase on point C and D. After Ximen (PC 4) or Daling (PC 7) were pressed to block Neiguan (PC 6), the value of TCE on Quze (PC 3), point A and point B were decreased during acupuncture Neiguan (PC 6), and increased after the block was removed, but there was no significant difference. Conclusion: Sham acupuncture has also some effects on body, it can increase energy metabolism of local skin, it may be the reason that shallow acupuncture without qi amving can obtain clinical efficacy. The operation method of traditional qi arriving acupuncture can increase energy metabolism of relevant meridian skin, mechanical press can reduce this effect.

Aim To investigate the effects and mechanisms of CCK-8 on IL-1? induced proliferation of RSC-364, a rat fibroblast-like synovial cell line. Methods MTT colorimetric assay and Western blot were used to measure cell proliferation and p38MAPK phosphorylation level to elucidate the mechanism of CCK-8 in IL-1? induced RSC-364 proliferation. Results CCK-8 significantly inhibited IL-1?-induced RSC-364 proliferation at 10 -12 , 10 -10 , 10 -8 , 10 -6 mol ? L -1 , and IL-1?-activated p38MAPK activity at 10 -10 , 10 -8 , 10 -6 mol?L -1 in a dose-dependent manner. The effect of CCK-8 was blocked by CR1409 (a CCKA-receptor antagonist) and CR2945 (a CCKB-receptor antagonist). Conclusion CCK-8 inhibits IL-1?-induced RSC-364 proliferation, probably by reducing p38MAPK activity through CCKA and CCKB receptors.
