Objective To compare the probability of anastomotic leak in the Chinese patients with carcinoma of esophagus using anastomat anastomose and manual anastomose in order to provide some refer -ence for patients with carcinoma of esophagus .Methods By meta-analysis, we made a comprehensive a-nalysis of 12 literatures published in China on anastomat anastomose and manual anastomose in preventing anastomotic leak in patients with carcinoma of esophagus .Results The probability of anastomotic leak in patients with carcinoma of esophagus was obvious heighten in using anastomat anastomose compared to that in using manual anastomose,with the combined odds ratio(OR)value being 0.53(95%CI:0.40-0.71) >0,( P <0.01 ).Conclusion To preventing anastomotic leak in patients with carcinoma of esophagus , anastomat anastomose is more predominant than manual anastomose .

Objective To compare the screening effects between Wells and revised Geneva scores on suspected acute pulmonary thromboembolism (APTE),and to explore a optimum screening method for APTE in the emergency department of China.Methods The study was carried out by using random,crossed,prospective methods to compare the screening effects between Wells and revised Geneva scores for 167 suspected APTE patients in the emergency department of the First Affiliated Hospital of Xiamen University.Results The areas under the receiver operating characteristic curve of Wells and revised Geneva scores for screening APTE in the emergency department were (0.917 ± 0.022 ) and (0.927 ± 0.020),respectively ( P ＜ 0.05 ).The diagnostic concordance between the two score systems for predicting APTE was poor (Kappa value =0.276 ). In addition, the difference between their hierarchical discrimination for the possibility of APTE was statistically significant ( P ＜ 0.05 ).Compared with revised Geneva score,fewer patients were diagnosed with low clinical probability of APTE and more patients were diagnosed with intermediate or high clinical probability of APTE through Wells score.The patients with low chnical probability of APTE were excluded from pulmonary embolism in Wells or revised Geneva score.At intermediate clinical probability,the accuracy rate of Wells score for predicting APTE (9.64％) was lower than that (32.84％ ) of revised Geneva ( P ＜ 0.05 ).At high clinical probability,there was no significant difference between their accuracy rate [ (67.24％ vs.86.21％),P＞0.05]. Conclusions Revised Geneva score is more suitable than Wells score in screening suspected APTE patients in the emergency department in our country.

To establish an HPLC method to determine osimertinib mesylate,Agilent ZORBAX Eclipse Plus C18 column (4.6 mm × 250 mm,5 μm) was used with a mobile phase consisting of methanol-buffer solution (20 mmoL/L NaH2PO4,pH 3.0 adjusted with 85％ H3PO4) (50 ∶ 50) at the flow rate of 1.0 mL/min.The detection wavelength was 210 nm,and the column temperature was kept at 35 ℃.The calibration curve was liner over the range from 50％ to 150％ of determination concentration (0.201 1-0.603 2 mg/mL,r =0.999 9).The limit of quantitation (LOQ) and limit of detection (LOD) were 0.32 μg/mL and 0.08 μg/mL,respectively.The contents of osimertinib mesylate in samples were 100.1％,99.5％ and 99.7％.Good chromatographic separation of osimertinib mesylate and its related substances,including synthetic impurities and degradation products,were obtained.The established HPLC method is specific,accurate,simple and durable,and could be used for the determination of osimertinib mesylate.

Objective Measuring the displacement and deformation of the fifth screw under different tensile force before or after adultal internal fixation with compressing steel plate for femoral fractuer by digital speckle correlation method.And analysis of the displacement and deformation after reducing the number of screws.Aimed at providing a theoretical basis for clinical femoral internal fixation with compressing steel plate about the number of screws. Methods Taking the antisepsis femoral specimen of grown-ups, embedding and fixing with tooth powder after removing the soft tissue, producing a fixed model in the 1/2 femur.Fixing steel plate below the lateral femur subperiosteal with five screws through the fourth floor of cortical bone on both sides of the fractures, samples were divided into 10 states, group A-J were measured by orders, under the rally of 400 N,500N , measuring the displayment of the fifth screw with CSS-44100-e-universal test machine for loading rally experiment ,and automatic data processing. Results For analysis of variance, the mean displacement measurements of the fifth screw under rally of 400N,500N, B-J group and A group have significant differences(P<0.05). The mean deformation measurements of the fifth screw under rally of 400N,500N, group A and group F-J group have significant differences(P<0.05);group A and B-E group have no significant differences.Conclusion In a certain range, the fracture displacement and the numuber of the screws show negative correlation. The screws near the fracture line for femoral compression plate internal fixation of femoral fractuer is easily broken because of the too large deformation.

Objective To detect the levels of IL-1, IL-6,TNF-αand IFN-γin serum and colon tissue of rat mod-els of ulcerative colitis with spleen and kidney Yang deficiency, and to explore their roles in the pathogenesis of ulcerative colitis ( UC) .Methods The rat model of ulcerative colitis with Yang deficiency of spleen and kidney was induced by perfusion of rhubarb decoction plus intramuscular injection of hydrocortisone and combined with TNBS (2,4,6-trinitro-benzenesulfonic acid) and ethanol enema.Sixty SPF wistar rats ( body weight 180 ±10 g, male:female=1:1) were ran-domly divided into blank control group, UC model with spleen kidney Yang deficiency for 7 days, 14 days and 21 days groups, respectively.The levels of IL-1, IL-6, TNF-αand IFN-γin serum and colon tissue were detected by ELISA.Re-sults Compared with the blank group, the levels of IL-1, IL-6, TNF-αand IFN-γin serum and colon tissue of rat UC model group with spleen kidney Yang deficiency were greatly increased (P<0.05), especially evidently increased in the model group at 21 days.Conclusions The pro-inflammatory cytokines IL-1, IL-6, TNF-αand IFN-γplay an important role in the pathogenesis of ulcerative colitis with syndrome of spleen and kidney Yang deficiency.

Objective To assess the mid-term and long-term efficacy of the permanent inferior vena cava filter in the treatment of deep vein thrombosis of lower limb and discuss the clinical significance of inferior vena cava filter.Methods Retrospectively analyze on the 86 cases with deep vein thrombosis of lower limb (41 males and 45 females,aged 50 to 94 years,mean age was 71.8 years) treated with implantation of permanent inferior vena cava filter in inferior vena cava from Janunary 2010 to October 2015.In these patients,there were 51 cases with embolism in the left leg,25 cases in the right leg,10 cases in both legs and 6 cases were accompanied with pulmonary embolism.The cases without contraindication underwent catheter directed thrombolysis and even percutaneous transluminal angioplasty or stents subsequently if necessary after inferior vena cava filter implantation.All the cases with no contraindication were treated with anticoagulant therapy.Results All the 86 patients were implanted inferior vena cava filter (B.Braun Vena Tech LP 76 and Cordis TrapEase 10)successfully.Sisty-five cases were underwent inferior wena cava filter implantation only,while 21 cases were treated with inferior vena cava filter implantation and catheter directed thrombolysis or even percutaneous transluminal angioplasty and stents.During the follow-up period(12 to 81 months,mean time was 51 months),27 patients died dueing to malignant tumor(17 cases) and other diseases (10 cases) rather than complications caused by inferior vena cava filter.Three patients had recurrence of deep vein thrombosis and 2 patients suffered from the thrombosis induced by stenosis of stents.Inferior vena cava filter appered tilted with angle less than 15 degrees in 6 cases.Three cases suffered from new thrombosis below the filter and 2 cases complained of the filter migration.No case was found with fracture of filter,perforation of the inferior vena cava,bleeding or pulmonary embolism(new onset or recurrent).Conclusions Application of permanent inferior vena cava filter may cause complications,though it is an effective approach to prevent pulmonary embolism in patients with deep vein thrombosis of lower limb.However,permanent inferior vena cava filter may be fit for patients with old age,incurable cancer or limited expected life.

Objective To investigate the alteration of energy metabolism and oxidative injury in the myocardia suffering from lethal ventricular tachyarrhythmia (LVTA). Methods Two LVTA-SCD SD rat models, induced by aconitine injection or coronary artery ligation (CAL), respectively, were developed. Rats that died from over-anaesthesia or CAL-induced heart failure were served as their controls, respectively. Mitochondrial membrane potential (MMP), reactive oxygen species (ROS), malonaldehyde (MDA), phosphocreatine (PCr) in the ventricular myocardia, and serum troponin I (cTnI) were detected, and compared between LVTA rats and their controls. Results Fourteen ACO-LVTA and six CAL-LVTA rats were successfully developed. As compared to their controls, ACO-LVTA and CAL-LVTA rats had higher ROS and MDA content, and lower concentration of PCr in the ventricular myocardia. MDA content in ACO-LVTA group is signiifcantly higher than that of its control (P<0.05). MMP in myocardia of ACO-LVTA is lower than that of its control, but is higher than those of two CAL groups. Serum cTnI in rats of both LVTA models is higher than those of their controls and pre-treated control. Specially, serum cTnI in CAL-LVTA was signiifcantly higher than that of ACO-LVTA and its control (P<0.01). The myocardial ROS content is correlated with the duration of VT and VF (P<0.05), with correlation coefifcients being 0.44 and 0.46, respectively. Conclusions After LVTA, the ventricular myocardia had lower MMP and PCr content, higher concentration of ROS, MDA, as well as higher serum cTnI than their controls, indicative of oxidative injury and alteration of energy metabolism under LVTA-SCD.

Objective To detect mechanism of action mode of Jiuxieling Granules in spleen and kidney yang deficiency ulcerative colitis. Methods The perfusion of Rhei Radix et Rhizoma Decoction plus intramuscular injection of hydrocortisone and combined with TNBS and ethanol enema were employed to establish UC animal model. Ninety rats were randomly divided into blank group, model group, SASP group and Jiuxieling Granules 7 days, 14 days and 21 days groups. All treatment groups received relevant medicine intervention. The levels of IL-1, IL-6, TNF-α, and IFN-γin serum and colon tissue were detected by ELISA. Results Compared with the blank group, the levels of IL-1, IL-6, TNF-α, and IFN-γ in serum and colon tissues of rats in model group increased (P<0.05);compared with the model group, the levels of IL-1, IL-6, TNF-α, and IFN-γin serum and colon tissues of rats in treatment groups were reduced greatly (P<0.05), among which Jiuxieling Granules 21 days group showed the most obvious effects (P<0.05). Conclusion Jiuxieling Granules can regulate the normal secretion of the levels of IL-1, IL-6, TNF-α, and IFN-γin serum and colon tissue of model rats, and inhibit inflammation and protect colonic mucosa.

A total of 192 patients with sepsis were tested by Montreal Cognitive Assessment (MoCA) for a preliminary diagnosis of whether or not there was sepsis associated encephalopathy (SAE) according to their test results.SAE was diagnosed or excluded after consultations and comprehensive analysis on the basis of clinical manifestations and auxiliary examination results.The scores of the patients in this group were (25.7 ± 3.3) points.The sensitivity of MoCA for screening SAE was 0.776 and its specificity 0.963.The rate of diagnostic coincidence between MoCA and comprehensive analysis for SAE was 0.880.The diagnostic concordance between two diagnostic methods of SAE was excellent (kappa value =0.753 ± 0.048,P =0.000).The area under the receiver operating characteristic (ROC) curve of MoCA for screening SAE was 0.929 ± 0.019 (P =0.000) ; the optimal cutoff value was 25.5 points; and its sensitivity was 0.779 and specificity 0.962.And negative correlations existed between score of MoCA and age,disease course and co-existing shock or multiple organ dysfunction syndrome (P ＜ 0.05).

Objective To review the surgical methods and mid-term results of mitral valve repair in pediatric patients with moderate to severe mitral regurgitation (MR).Methods 132 children with moderate to severe MR,aged (18.9 ± 7.2)months,weighted(11.3 ±4.8) kg.The etiology for mitral regurgitation is congenital heart disease in 126 cases,infective endocarditis in 5 cases and Marfan syndrome in 1 case.Mitral valvuloplasty(MVP) was performed with cardiopulmonary bypass under moderate systemic hypothermia.The methods of MVP included annuloplasty,annuloplasty ring,cleft closure,reconstruction of posterior leaflet.The coucomitant cardiac anomalies were treated at the same time.The results of repair were evaluated by saline injection test and transesophageal echocardiography (TEE) during operation.Results Intra-operative TEE results: 131 cases had none to mild MR,and only one case had moderate MR.The patient underwent second repair immediately,subsequent TEE was mild.Mean cardiopulmonary bypass (CPB) time was (80.0 ± 31.1) minutes.Mean aortic clump time was (48.0 ± 17.9) minutes.The in-hospital mortality was 2.3％ (3 cases died).One died of heart failure on postoperative day 7,the other died of low cardiac output syndrome resulting on postoperative day 2.Another one was large ventricular septal defect(VSD) with pulmonary hypertension (PH),died of pulmonary infection.Mean postoperative ventilation time was (34.4 ± 31.9) hours,and mean postoperative inhosptial time was (9.0 ± 5.4) days.The average follow-up period was (40.5 ± 8.3) months (2 to 74 months).122 cases were fully followed up.Echocardiography showed that moderate MR was in 7 patients,and 3 patients had severe MR.4 patients underwent re-do mitral valve repair or mitral valve replacement.There was no late death.The overall survival rate at 5 years was 97.7％ and the overall freedom from reoperation at 5 years was 92.0％.Conclusion Pediatric patients with moderate to severe MR need early surgical treatment,the early and mid-term results were satisfactory.Individualized treatment protocol based on specific pathology was the keypoint of surgical therapy.
