Objective To compare the effects of expectoration by high frequency back tapping with both hands and traditional expectoration by tapping back with a single hand on pulmonary complications in esophageal cancer patients having undergone radical resection with video-assisted thoracoscopic surgery (VATS). Methods Sixty patients after radical resection for esophageal cancer with VATS from May 2013 to January 2014 were set as the control group, in which expectoration by tapping the back with a single hand. Another 60 patients after radical resection for esophageal cancer with VATS from February 2014 to July 2014 were set as the observation group, in which the expectoration by high frequency tapping the back with both hands. The two groups were compared in terms of pulmonary complications. Result The incidence of atelectasis and pulmonary infection in the observation group were lower than those with a single hand in the control group (all P<0.05). Conclusion For the patients having undergone radical resection of esophageal carcinoma with VATS, the expectoration with high frequency back tapping with both hands is more effective in lowering atelectasis rate than that with a single hand.

Objective To understand the levels of plasma endothelin (ET) and calcitonin gene-related peptide (CGRP) in cough variant asthma(CVA) patients, and to investigate their correlation and clinical implications. Methods Thirty CVA patients,30 typical bronchial asthma patients and 25 healthy controls were recruited. Three milliliter limosis venous blood were drawn from each patient to measure the levels of plasma ET and CGRP by radioimmanity. Results ①The levels of ET in the CVA group and typical bronchial asthma group were higher than that in healthy controls (P < 0.01). Their values were (103.58±28.66) ng/L, (129.37±27.28) ng/L and (72.63±21.52)ng/L, respectively. The levels of CGRP in the CVA group and typical bronchial asthma group were (7.62±2.56) ng/L and(6.63±2.09)ng/L The level of CGRP in the healthy controls group was (21.60±3.29) ng/L. The first two groups were lower than the latter(P < 0.01). However, there was no significant difference between the CVA group and typical bronchial asthma group(P >0.05). ②ET and CGRP were negatively correlated in both CVA group(r= -0.819,P<0.05) and typical bronchial asthma group(r= -0.738,P<0.05). Conclusions ET and CGRP were negatively correlated in both CVA group and typical bronchial asthma group, which means that ET and CGRP were a couple of antagonistic factors participated in the regulation of CVA, and may play an important role in the process of CVA.

Objective To study effect of Shikonin on human cervical cancer Hela cell growth suppression in vitro and its mechanism. Methods MTT assay was used to examine the growth inhibition of Shikonin in Hela cells.And then, the measurement of both ROS Levels and Mitochondrial Membrane Potential (ΔΨm ) were performed to clarify the mechanism of antitumor in Hela cells by Shikonin.Results Shikonin significantly inhibited the growth of Hela cells in a concentration-dependent manner.Shikonin increased generation of en-dogenous reactive oxygen species ( ROS) and decreased mitochondrial membrane potential.Furthermore, anti-oxidants N-acetylcysteine ( NAC) could significantly reduce the antitumor activity of SK in Hela cells.Conclusion These results suggest that mitochondrial aerobic respiration shift and endogenous ROS augmentation contribute to the action of Shikonin against Hela cells.

Objective: To clone the Fab gene of a monoclonal antibody (mAb) BDI against human bladder cancer and its expression in E. coli. Methods: Fd and K genes of mAb BDI were cloned by RT-PCR and inserted into an Fab expression vector. Phage displaying Fab and soluble Fab were expressed in E. coli. The N-terminal sequence of VH region was corrected by PCR mediated mutagenesis. The antigen-binding characteristics of the Fab were tested by ELISA and immu-nohistochemistry. Results: Fd and K genes were cloned into the expressing vector p3MH and the phage displaying antibody and soluble Fab were expressed in E. coli, which showed weak binding activity to bladder cancer cells. Correction of the N-terminal sequence of the VHimproved the biding activity dramatically. The feasibility of the application of the Fab in phage antibody library screening was confirmed by a simulated panning procedure. Conclusion: The Fab gene of an anti-human bladder cancer mAb was expressed in E. coli. The importance of the N-terminal sequence on antibody binding activity was suggested.

Objective To investigate the prevalence and associated factors of fecal incontinence (FI) and urinary incontinence (UI) in postpartum Chinese women.Methods Questionnaires about FI and UI symptoms were completed via telephone interviews conducted within six months after delivery.Multi-variant Logistic analysis was applied for relation between delivery mode and FI or UI.Results (1) Two thousand and twelve postpartum women were admitted into this study,among which 14 (0.7％) had FI within 6 months after delivery.Logistic regression analysis showed that FI was significantly associated with forceps delivery (OR =20.09,95 ％ CI:3.64-110.90,P =0.000),and mediolateral episiotomy (OR=6.11,95％ CI:1.29-28.80,P=0.024).(2) Among the 2012 women,the prevalence of UI,stress urinary incontinence (SUI),urgent urinary incontinence (UUI)and mixed urinary incontinence (MUD was 10.04％ (n=202),8.15％ (n=164),0.94％ (n=19)and 0.94 ％ (n =19),respectively.Logistic regression analysis found that SUI prevalence was related to maternal age (OR =1.07,95％ CI:1.04-1.11,P =0.000),maternal weight before delivery (OR=1.04,95％ CI:1.02-1.06,P=0.001),neonatal head circumference (OR=1.20,95％ CI:1.05-1.39,P =0.010),mediolateral episiotomy (OR =4.96,95 ％ CI:3.05-8.07,P =0.0005 ),spontaneous vaginal delivery (OR=5.22,95％ CI:2.53-10.76,P=0.000) and forceps delivery (OR=9.20,95％ CI:4.07-20.79,P=0.000).UUI was related to maternal weight before delivery (OR=1.51,95％ CI:1.12-2.05,P=0.008).MUI was related to maternal weight before delivery (OR=1.06,95％ CI:1.00-1.11,P=0.049),duration of second stage of labor (OR=1.01,95％ CI:1.00-1.03,P =0.010),mediolateral episiotomy (OR =7.76,95％ CI:1.42-42.52,P=0.017) and forceps delivery (OR=15.21,95％ CI:1.61-143.44,P=0.018).(3) The prevalence of SUI was higher at 4 days and 42 days after delivery (7.95％ and 9.10％).Conclusions (1) F1 and UI prevalence is lower in this study than in other reports.(2) Vaginal delivery is a risk factor for women's FI and UI,especially forceps delivery and mediolateral episiotomy.(3) Maternal age,pre-delivery weight,newborn head circumference,spontaneous vaginal delivery,forceps delivery and mediolateral episiotomy might increase the risk of UI.

Objective To compare the efficacy and safety of two kinds of homemade sirolimus-eluting stents (Firebird and Excel) for treatment of acute ST segment elevation myocardial infarction (STEMI) in patients who underwent percutaneous coronary intervention (PCI). Methods The 249 consecutive patients with STEMI who underwent PCI were randomly divided into two groups: Excel group (n=136) and Firebird group (n=113). They were followed up for 6-24 months, and coronary angiography was reviewed average 12 months later. The primary endpoints were major adverse cardiac events, including death, reinfarction and target vessel revascularization. The second endpoints included late luminal loss and restenosis 12 months after treatment. Results There were no significant differences in baseline data, coronary arterial lesion before operation, and immediateness condition after PCI between the two groups (all P＞0.05). Within follow-up, there were 2 (1.47%) death cases and 1 (0.88%) death case, 1 (0.74%) and 1 (0.88%) nonfatal myocardial infarction case, 2 (1.47%) and 2 (1.77%) target vessel revascularization cases in the two groups respectively (all P＞0.05). There were no significant differences in late luminal loss of in-stent and in-segment, the rates of in-stent restenosis, in-segment restenosis and stent thrombosis, the in-stent minimal lumen diameter and in-segment minimal lumen diameter between the two groups (all P＞0.05). Conclusions The two kinds of homemade sirolimus-eluting stents may have similar efficacy and safety in patients with STEMI treated with primary PCI.

Objective To determine whether field triage would reduce median contact-to-device ( C2D ) time in patients with ST-segment elevation acute myocardial infarction ( STEMI ) . Methods Consecutive patients with STEMI underwent primary percutaneous coronary intervention( PCI) from March 2010 to February 2014 in Shanghai Pudong Gongli Hospital were analyzed. Patients were divided into two groups. A total of 121 patients were admitted by field triage and 101 patients by non-field triage. The primary study point was C2D time and the study points secondary included ( door-to-balloor, D2B) time, peak Troponin I ( TnI) levels, hospital mortality and 30 days follow-up mortality. Results Baseline and procedural characteristics between the two groups were comparable. Comparing to non-field triage group, the C2D time was reduced [(92. 0 ± 56. 0)min vs. (131. 0 ± 61. 0)min,P﹤0. 01]. The D2B time was lower in the field triage group vs. the non-field triage group [(55. 0 ±26. 0)min vs. (96. 0 ±31. 0)min,P﹤0. 01]. The percentage of patients with C2D time less than 90 minutes increased significantly from 85. 1% to 98. 3%( P﹤0. 01 ) in the field triage group. Peak TnI level was significantly reduced in the field triage group [(23. 5 ±22. 0) μg/L vs. (43. 5 ± 39. 0) μg/L,P﹤0. 01]. In-hospital mortality and 30 days follow-up mortality did not significantly differ between the 2 groups (3. 3% and 3. 0%, P=0. 885;3. 3% and 5. 0%, P=0. 544, respectively). Conclusions In STEMI patients, field triage was associated with significantly reduced C2D and D2B times.

Objective To investigate the relationship between the serum SRC-3 levels and the bone loss severity in postmenopausal women. Methods Fifty-eight PMW with osteopenia or osteoporosis and nineteen healthy PMW were enrolled in this study from June 2012 to September 2013. BMD at the lumbar spine and femoral neck were observed by DXA Lunar Prodigy Vision. The levels of serum SRC-3 were detected by ELISA. The diagnosis value was evaluated by the ROC curves analysis. Results The levels of serum SRC-3 were significant higher in the normal group than those in the osteopenia or the osteoporosis groups (P<0.001 for both), no statistical significance was found between the osteopenia and the osteoporosis group(P=0.056). The levels of serum SRC-3 were negatively correlated with the BMD diagnosis grading (r=-0.543, P < 0.001). By using the ROC curve analysis, the serum level of SRC-3 for PMW with osteoporosis and osteopenia were found to be 0.297 ng/mL and 0.347 ng/mL, respectively. The levels of serum SRC-3 were positively associated with BMI (r=0.395, P<0.001) and LS-BMD (r=0.503,P<0.001) in the postmenopausal women. Conclusion SRC-3 might be an useful index to reflect the severity of lumbar spine bone loss.
