Objective To investigate the pharmacodynamics of remifentanil required to prevent laryngeal mask airway (LMA) insertion response in patients anesthetized with propofol by TCI. Methods Thirty-six ASA Ⅰor Ⅱ patients aged 18-59 yr with body mass index ＜ 30 kg/m2 undergoing elective breast operation were enrolled in the study. Propofol was administered by TCI at an effect-site concentration of 4.0 μg/ml. When the patients lost conciousness, TCI of remifentanil was started. The initial target plasma concentration of remifentanil was set at 2.9 ng/ml, and the ratio of two consecutive effect-site concentrations was 1.2. LMA was inserted at 3 min after the target effect-site concentration and the plasma concentration achieved the balance. Criteria of successful insertion were defined as Muzi score≤2 and the increase in MAP and HR≤ 15% of the baseline values within 3 min after insertion. EC50 was determined by modified Dixon's up-and-down sequential trial and the 95 % confidence interval was calculated. Results The EC50 of remifentanil was 2.75 ng/ml. The 95% confidence interval was 2.51-3.01 ng/ml. Conclusion The EC50 of remifentanil for suppression of cardiovascular response to LMA insertion is 2.75 ng/ml in patients anesthetized with propofol by TCI.

Purpose: To explore the therapeutic method for lameness caused by lumbar spinal stenosis. Methods: 28 cases of the patients with lameness were treated by puncturing Dachangshu (BL 25), Weizhong (BL 40), Chengshan (BL 57) and Kunlun (BL 60) and simultaneously another 26 cases were treated with routine method for control study. Results:After the treatments for four weeks, the scores of the symptoms in the two groups were remarkably elevated. In the acupuncture treatment, the results showed remarkable effect in 4 cases, effect in 21 cases. In the routine treatment, the results showed remarkable effect in 4 cases and effect in 8 cases. Conclusion: acupuncture treatment is better than the routine conventional treatment for lameness caused by lumbar spinal stenosis.

Objective To investigate the effect of resveratrol on autophagic flux of nasopharyngeal carcinoma CNE-2 cells, and to explore the underlying mechanism. Methods Nasopharyngeal carcinoma CNE-2 cells were divided into control group and resveratrol group. Cells in control group were normally cultured at 37℃and received no further treatment. Resveratrol group was added 40 μmol/L resveratrol 2 h before cells were culture at 37 ℃. Western blot analysis was performed to detect protein expressions of LC3B, p62, Beclin-1, phospho-mTOR (p-mTOR) and phospho-S6 (p-S6). The autophagic flux was detected under the confocal laser scanning microscopy through different color spots, after cells were transfected with adenovirus encoding GFP-mRFP-LC3. Results (1) The protein expression of LC3B was significantly increased and the protein expression of p62 was significantly decreased in resveratrol group compared with those of control group (P<0.05). There was no significant difference in Beclin-1 expression between two groups. (2) Compared to control group, expressions of p-mTOR and p-S6 were significantly decreased in resveratrol group (P<0.05). (3) Compared to control group, the red mRFP puncta were significantly increased, and the yellow GFP puncta were significantly decreased in resveratrol group (P<0.05). Conclusion Resveratrol promotes the autophagic flux of nasopharyngeal carcinoma CNE-2 cells, and the effects are possibly dependent on the activation of mTOR pathway-related proteins.

Objective To explore the correlation between the epicaridal adipose tissue (EAT)volume and the SNYTAX score in patients with coronary artery diseases and to evaluate its clinical value.Methods Epicardial fat volume of 102 patients with coronary heart disease in our hospital were measured on dual-source CT angiography images,SNYTAX scores were calculated,and level of blood lipids,blood glucose (Glu),blood pressure,renal functional parameters and body mass index(BMI)were collected.Depending on SNYTAX scores,patients were divided into three groups (mild 0-22,moderate 23-32 and severe>33).The difference of EAT volume between groups and correlation with other indicators were analyzed.With indictors statistical significant in one-factor analysis,multi-ple regression equation was constructed to evaluate the risk factors of coronary artery diseases,particularly correlation between EAT volume and SNYTAX score.Results EAT,TC,TG,HDL,HbALc,GLu and BMI were significant different between three groups. Pearson regression showed that EAT,TC,GLu and BMI were independently risk factor in relation to the value of SNYTAX.Among them,standardized regressive coefficient of the EAT volume was the highest (β=0.52).Conclusion EAT volume is significantly positively correlated with the SNYTAX score in coronary heart disease,which can be as an effective predictor for its severity and prognosis.

BACKGROUND:Synthetic patch as an important substitute to pelvic tissue can replace damaged pelvic fascia tissue, and has been widely used in the pelvic floor reconstruction. OBJECTIVE:To observe the efficacy and complications of pelvic floor reconstruction with mesh, and to explore its safety and effectiveness. METHODS: Forty-five pelvic organ prolapse female patients were divided into two groups according to patient’s wilingness: experimental group, pelvic floor reconstruction with mesh (n=25); control group, transvaginal hysterectomy combined with vaginal wal repair (n=20). Perioperative conditions were recorded, and uterine prolapse staging, complications, pelvic floor function, pelvic discomfort, as wel as an objective cure rate were evaluated in the two groups during the folow-up. RESULTS AND CONCLUSION:Compared with the control group, the experimental group was characterized as shorter operative time, less amount of bleeding, milder infections, and faster recovery (AlP < 0.05). At 6 months of folow-up, the score on uterine prolapse staging was higher in the experimental group than the control group; at 12 months, the scores on pelvic floor function and pelvic discomfort as wel as the incidence of complications were significantly lower in the experimental group (P < 0.05), but the objective cure rate was higher compared with the control group (P < 0.05). These findings suggest that pelvic floor reconstruction with mesh for pelvic organ prolapsed can reduce the operative time and blood loss and promote postoperative recovery. Meanwhile, it can significantly improve pelvic floor function, pelvic discomfort, postoperative complications, the rate of exposure, and the objective cure rate, which is safe and effective during the short-term folow-up.

Objective To compare the effects of combination of maternal hydration and hands and knees posture with simple hands and knees posture on correction of breech pregnancy. Methods One hundred patients who were diagnosed breech pregnancy from November 2015 to November 2016 were assigned to experimental group and control group with 50 cases each according to individual willingness. The patients in experimental group received the combination of maternal hydration and hands and knees posture;while the patients in control group received simple hands and knees posture. Results Amniotic fluid index was (18.94±2.44)cm in experimental group and (15.97±2.33)cm in control group, the difference had statistic significance (t=6.239, P<0.05). The effective transfer rate and successfully used time was 92%(46/50) , (2.10 ± 0.75) weeks in experimental group and 64%(32/50), (4.27 ± 0.98) weeks in control group, the difference had statistic significance (χ2=11.422, P<0.05; t=-12.463, P<0.05). For primipara and multipara, the effective transfer rate was 90.91%(30/33), 16/17 in experimental group, and 68.75%(22/32), 10/18 in control group, the difference had statistic significance (χ2=4.986, 6.806, all P<0.05). The rate of vaginal and cesarean section deliveries was 86%(43/50), 14%(7/50) in experimental group, and 56%(28/50), 44%(22/50) in control group, the difference had statistic significance(χ2=10.928, P=0.001). Patients who had fetal movement or who didn′t have time to do correction or missed was 17.10%(46/269), 1.49%(4/269) in experimental group, and 12.55% (22/255), 7.06% (18/255) in control group. Conclusions @Therapic effects of combination of maternal hydration and hands and knees posture is much better than that of the simple hands and knees posture therapy on correction of breech pregnancy, which is worthy of popularization and application in clinic.

BACKGROUND:As one of the most serious pathological types of lumbar disc herniation, the nucleus pulposus of prolapsed style lumbar intervertebral disc herniation is like a cord or mass. And the nucleus pulposus compresses nerve roots and dural sac, which brings severe low back pain and/or cauda equina injury symptoms.OBJECTIVE:To compare the clinical efficacy of simple discectomy under the Quadrant system and minimally invasive transforaminal lumbar interbody Concorde fusion (MIS-TLIF) in the treatment of prolapsed and sequestrated lumbar disc herniation.METHODS:From January 2012 to January 2015, 58 patients with prolapsed and sequestrated lumbar disc herniation were enrolled in this study, including 36 patients in simple Quadrant group and 22 patients in MIS-TLIF group.RESULTS AND CONCLUSION:Significant difference was recorded in the visual analogue scale scores and Oswestry disability index at 1 week, 3 months and 18 months postoperation compared with preoperation in the two groups (P < 0.05). Compared with the simple Quadrant group, the visual analogue scale scores of low back pain and Oswestry disability index were significantly decreased in the MIS-TLIF group at postoperative 18 months (P < 0.05), but there was no significant difference in the visual analogue scale score of leg pain between two groups (P > 0.05). There were two patients with recurrent lumbar disc herniation in the simple Quadrant group. In summary, simple discectomy under the Quadrant system could achieve the similar satisfied effect as the MIS-TLIF, but the MIS-TLIF provides less low back pain.
