Objective:To study the effects of Shixinyatong buccal tablets(SBT)in patients after the extraction of mandibular third molar.Methods:150 cases of patients were divided into 3 groups(n =50).After tooth extraction the patients in SBT,cephalosporin and control groups were given SBT at 0.6 g,4 times per day,cepholosporin 0.5 g,2 times per day and no drug respectively.At the 3rd and 5th day the patients were followed up and their local symptoms were scored.The data were statistically analyzed with SAS 9.0 soft ware.Results:Between SBT and cepholosporin or control group there was no statistical difference in demographic data and impac-tion types of the teeth(P >0.05).The total symptom integral,primary symptom integral,minor symptoms,wound pain,redness, swelling degree and oral odor in SBT group were lower than those in control group(P <0.05)at the 5th day after tooth extraction.Be-tween SBT group and cephalosporin group there was no significant difference(P >0.05)in the total symptom integral,primary symp-tom integral,secondary symptom integral at the 3rd and the 5th day.Conclusion:Shixinyatong buccal tablet is effective in the preven-tion of complications after the extraction of mandibular third molar.

OBJECTIVETo investigate diagnostic efficacy of transvaginal three-dimensional hysterosalpingo-contrast sonography (3D-HyCoSy) in assessing tubal patency with chromolaporoscopy.

METHODSA total of 157 infertile women underwent 3D-HyCoSy to evaluate tubal patency. Among these patients, 39 patients were also examined by chromolaporoscopy. The concordance of the two clinical assessment methods was analyzed by the Kappa coefficient test.

RESULTSAmong the 306 oviducts examined by 3D-HyCoSy, 99 (32.4%) were patent, 126 (41.2%) partially obstructed, and 81 (26.5%) completely obstructed. Diagnostic results with 3D-HyCoSy were not statistically different from those obtained in the 39 women (78 oviducts) who also underwent chromolaporoscopy, and the two methods showed a high concordance (k=0.747, P=0.000). The 3D-HyCoSy procedure had a sensitivity of 84.8% (28/33), a specificity of 96.2% (25/26), and positive and negative predictive values of 93.3% (28/30) and 86.2% (25/29) respectively.

CONCLUSIONTransvaginal 3D-HyCoSy can accurately reveal the spatial path and morphology of the oviduct and is a safe and effective method to evaluate tubal patency.

This paper focuses on issues needed to be clear towards the product quality supervision of medical devices in use. The life circle of medical devices, the supervision regarding its boundary, target, emphasis, basis and standards have been analyzed in turn. A clear and creative idea is also provided for theoretical exploration of the supervision on medical devices in use.

Objective To identify dosimetric predictors for the development of gastrointestinal toxicity in patients with pancreatic adenocarcinoma treated with TOMO radiotherapy .Methods From January 2014 to Janu-ary 2015 ,we analysed the medical records of 68 pancreatic cancer patients who received helical tomotherapy from Air Force General Hospital .The stomach and duodenum were contoured separately to determine their dose volume histogram(DVH)parameters.Chi-square test was employed to analyze the count data .Spearman correlation anal-ysis was used to analyze the relationship between occurrence of gastrointestinal toxicity and clinical and physical factors.Logistic regression models was performed to identify risk factors associated with gastrointestinal toxicity . Results The median follow-up was 9 months(4~16 months).18 patients experienced grade II acute gastroin-testinal toxicity ,1 patient experienced grade Ⅲ acute gastrointestinal toxicity , whereas 17 patients experienced grade II late gastrointestinal toxicity ,1 patient experienced grade Ⅲlate gastrointestinal toxicity .On UVA,the vol-ume,Dmean,D1,D3,D5,D10,V5 to V40,and V5′to V45′of duodenum were significantly associated with GradeⅡor higher gastrointestinal toxicity ( P <0.05 ) .The MVA, V45′of duodenum was independent predictor for gradeⅡor higher gastrointestinal toxicity(P<0.05).The ROC analysis also showed that V45′of 0.5cm3 was the optimal threshold to predict for gastrointestinal toxicity for the entire cohort .Conclusion V45′of duodenum is of greater importance in the judgment of occurrence of hypofractioned radiation -induced gastrointestinal toxici-ty.

0.05).Conclusion The application of oxygen inhalation with a special facial mask during propofol-sedated gastroscopy appears to be more safer than that of oxygen inhalation via snuffle tube.

Objective To observe the hemodynamic changes during operation of piggyback liver transplantation.Methods The Swan-Ganz catheter was inserted and the parameters of hemodynamics were analyzes in 36 patients with chronic hepatic diseases following piggyback liver transplantation. The cardiac output(CO)and pulmonary arterial pressure(PAP)were measured.Results CO and PAP were decreased significantly in the anhepatic phase(P

Objective:To explore the mediating effect of positive emotion on relationship between cognition reappraisal and meaning of life in freshmen.Methods:Totally 192 freshmen[62 males and 130 females,aged 18 to 22 years,mean age (20 ± 2) years] were assessed with the Chinese version of the Emotion Regulation Questionnaire (ERQ),Positive words of the Positive and Negative Affect Scale (PANAS) and Chinese version of the Meaning of Life Questionnaire (MLQ).Interval of 3 months of longitudinal data was used to investigate the mediating role of positive emotions in cognitive reappraisal sense and meaning of life.Results:The EPQ scores were positively correlated with the scores of PA,MLQ-P,and MLQ-S(r =0.17-0.26,Ps ＜ 0.05).The PA scores were positively correlated with the scores of MLQ-P and MLQ-S (r =0.16-0.35,Ps ＜0.05).Bootstrap test showed that positive emotions mediated meaning of life through cognitive reappraisal (95％ CI:0.065-0.295).The structural equation model proved to exhibit an appropriate data fit (x2/df=1.58,RMSEA =0.06,CFI =0.98,GFI =0.95).Conclusion:It indicates that cognitive reappraisal is related to meaning of life and positive emotions,and positive emotions mediate the relationship between cognitive reappraisal and meaning of life among freshmen.

Background Research showed that transforming growth factor-β2 (TGF-β2) promotes scar formation.But its mechanism in scarring after glaucoma filtration surgery is worthy of studying.Objective This study was to investigate the effect of TGF-β2 on myofibroblast transition of human Tenon fibroblasts (HTFs) and scarring after glaucoma filtration surgery.Methods Tenon capsular tissue was obtained from 3 patients with strabismus during the surgery and was incubated in DMEM with 10％ fetal bovine serum (FBS).The cells were collected and passaged in the free-serum medium for 24 hours,and then 1,2,5,10,20 μg/L TGF-β2 was added into the medium respectively,to induce the transformation of HTFs,and 2 μg/L or 5 μg/L TGF-β2 was used to treat the HTFs for 6,24,48 and 72 hours.The control group was not treated with TGF-β2.The expressions of α-smooth muscle actin (α-SMA) and phosphorylation of the signaling proteins (pSmad2) in HTFs were detected by Western blot assay.The expressions of α-SMA and F-actin were located by cell immunofluorescine technique under the confocal immunofluorescence microscopy.Cell contractility was determined by collagen gel contraction assays.This study was approved by Ethic Committee of Institute of Surgery Research of Daping Hospital,and informed consent was obtained from each patient or custodian initial of the study.Results The expression of α-SMA protein in the HTFs was increased significantly after the treatment of TGF-β2 in comparison with the control group and reached a peak at 24-48 hours.The α-SMA expression was gradually weakened in the 10 μg/L TGF-β2 groups.Little of α-SMA and F-actin were expressed in the control group.However,strong staining for α-SMA and F-actin were observed in the 1,2 and 5 μg/L TGF-β2 groups and then the staining weakened at the concentration of 10 μg/L.In addition,pSmad2 showed a stronger expression in the 2 μg/L TGF-β2 group than that in the PBS group and FBS group,with the strongest expression in 30 minutes through 2 hours.The untreated gel contracted (78.00±3.13)％ from its initial size,and contraction in the 1,2,5,10 μg/L TGF-β2 group were (63.88±1.78)％,(20.69±0.65)％,(19.49-±0.54)％,(16.24±0.84) ％,respectively,TGF-β2 increased HTFs contraction significantly (Fgroup =859.400,P =0.000).Conclusions TGF-β2 can induce transdifferentiation of Tenon fibroblast into myofibroblast and increase cell contractility,with a concentration-dependent and time-dependent pattern to an extent.It may be the mechanism of scar formation after glaucoma filter surgery.
