Objective To investigate the effects of combined general and epidural anesthesia on intestinal barrier function in patients with obstructive jaundice after surgery.Methods Forty patients with obstructive jaundice,male 1 5 cases,female 25 cases,aged 26-65 years,of ASA Ⅰ-Ⅲ,with TBIL >100 μmol/L were randomly divided into two groups (n =20):the general intravenous anes-thesia group (group GA)and the combined general and epidural anesthesia group (group GE).Pa-tients of group GA with oxygen mask rapid intubate induction of endotracheal after general anesthesia. Patients of group GE take left side line of T8~9 or T9 ~1 0 segmental epidural puncture and insert cathe-ter,after changing the hypothesis to be 2% lidocaine 5 ml for test quantity,confirm without anesthe-sia complications and other abnormalities after general anesthesia 5 minutes later.Peripheral venous blood was sampled when entering the operating room (T1 ),and at the end of operation (T2 ),24 hours after operation(T3 )and 48 hours after operation (T4 ).The concentration of D-lactate (D-LA) was measured using ELISA method.Also polymerase chain reaction (PCR)was performed for quali-tative detection of Escherichia coli specific beta galactosidase gene BG.Results Compared with T1 , Plasma D-LA level in two groups at T2-T4 were increased gradually and it was significantly higher in group GA than in group GE at T2-T4 with significant difference (P <0.05).The Escherichia coli DNA test was negative at T1 ,the positive rate of Escherichia coli DNA gradually increased,and it was significantly higher in group GA than in group GE at T4 with significant difference(P <0.05).Conclusion Compared with the general intravenous anesthesia, general anesthesia combined with epidural anesthesia may relieve the intestinal barrier injury in patients with obstructive jaundice after surgery.

Objective To study whether closed reduction and interlocking intramedullary nailing will worsen the injured radial nerve associated with the fracture of humeral shaft.Methods Of the 353 patients with fracture of humeral shaft who received operation from January 2002 to January 2005,63 ones were complicated with preoperative injury to their radial nerve.A retrospective analysis was done of their physical examination records, operative records,X-ray films and results of the treatment.Eleven cases were treated with closed reduction and interlocking intramedullary nailing,and 52 cases with open reduction and internal fixation of plates and screws fol- lowed by exploration to the radial nerve.Chisquare test of PEMS 3.1 system was adopted to analyze the clinical data. Results The radial nerve was embedded by the fracture ends in nine cases(17.3%)of the 52 cases,and con- tused in the other 43 ones.In the 63 cases,The injured nerves recovered spontaneously 2 to 12 weeks postoperatively except in twn cases.All the eases got bony union 3 to 4 months after operation.Closed reduction and interlocking intramedullary nailing has hardly more harmful effects on the injured radial nerve assoeiated with the fracture of humeral shaft than open reduction and internal fixation of plates and screws followed by neural exploration.Con- clusion Closed reduction and interlocking intramedullary nailing is fit for the freatment of fractures of humeral shaft with radial nerve injury.

Diabetic keratopathy (DK) is a common ocular complication of diabetes.Long-term hyperglycemia impairs many structures of the cornea, leading to corneal opacity and visual dysfunction.A large number of researches focus on the epithelium and nerve abnormities in DK, but the pathogenesis is not completely elucidated.Dendritic cells (DCs) are specialized antigen-presenting cells, linking innate and adaptive immunity, participating in the occurrence and development of diabetes and its complications.To date, there are many myths in relationship between DCs and DK to be solved, and there are a few researches that investigate the relation between DCs and the occurrence and development of diabetes.In this article, the pathogenesis and pathogenic changes of DK, the types and functions of different DCs, the relationship between DCs and chronic inflammation and delayed healing of corneal epithelium in DK, as well as the role of DCs in corneal neuropathy were reviewed in order to provide some references for further investigations about the pathogenesis and treatment of DK.

Objective To comparatively study the difference between thromboelastography (TEG)and light transmission ag-gregometry (LTA)in monitoring clopidogrel effect in patients with acute coronary syndrome.Methods 68 patients with a-cute coronary syndrome,who were in hospital from February to December 2013,were enrolled in this study.They received TEG and LTA to determine platelet aggregation.Results Clopidogrel effect was (47.84±26.04)% and (45.64±20.92)%respectively by TEG and LTA.There were negative correlation between LTAADP and TEGADP(r=-0.752,P<0.001),pos-itive correlation between LTAADP and MAADP(r=0.789,P<0.001),negative correlation between TEGADP and MAADP(r=-0.820,P<0.001).Conclusion There was a good correlation between the two methods.TEG can be used to evaluate thera-peutic effect of Clopidogrel effect.

Objective To investigate the effects of extracorporeal membrane oxygenation (ECMO) in severe cardiopaths with crisis. Methods Fourteen cases of severe eardiopaths with crisis were treated by ECMO with V A- ECMO technique, whose pump was centrifugal pump and whose tubes was spread byheparin. The cases included 8 fulminating myocarditis (FM) cases with ventricular arrhythmias or/and acute heart failure or/and cardiac shock and 6 acute myocardial infarction cases with pump failure or cardiac shock,in whom 10 cases with cardiorespiratory resuscitation. Haemodynamics and blood gas analysis, and so on were measured before and after treatment. Results The support time of ECMO was 3-106 h, mean (32.4±27.6) h. After ECMO mean arterial blood pressure (MAP), left ventricular ejection fraction (LVEF), left ventricular end-diastolic dimension (LVEDd), partial pressure of arterial oxygen, saturation of blood oxygen improved (P < 0.05 or < 0.01 ), negative value of base excess decreased significantly( P < 0.01 ). MAP had notchanged before and after stopping ECMO [ (80.02±10.20) wan Hg (1 mm Hg = 0.133 kPa) vs (76.34±9.15) mm Hg] (P > 0.05), however, LVEF and LVEDd improved continually (P <0.05). Conclusion ECMO can provide oxygen supply and stable circulation volume for severe cardiopaths with crisis to recover cardiorespiratory function or save valuable time to treat primary disease.

To understand the impact of salvianolate injection treatment of liver and kidney function using different from the hospital information system nationwide 18 large three hospitals (hospital information system, HIS) to extract using salvianolate age 18-80 years-old patient, a total of 10 470 cases, depending on the treatment used to have two times before and after treatment 7 d aspartate aminotransferase (AST), alanine aminotransferase patients (ALT), serum creatinine (Cr) and blood urea nitrogen (BUN) measurement indicators grouped according salvianolate continuous use different treatment patients were divided into two groups, continuous medication time > 14 d were defined as the observation group, ≤ 14 d were defined as the control group, continuous medication longer than 31 d were not included in the analysis. Each index number of the observation group and the control group were: ALT (268/1 465), AST (270/1 585), Cr (278/1 582), BUN (278/1 611). After using propensity score methods to balance two groups of covariates, based on unweighted logistic regression logistic regression propensity score weighting combined with propensity score weighting to adjust for covariates logistic regression of liver and kidney function in the two groups were analyzed. The results showed: three logistic regression analysis showed no likelihood of ALT, AST, Cr targets two groups of patients with abnormal statistically significant difference, continuous medication time > 14 d may increase the risk of abnormal BUN indicators, comprehensive analysis still can not explain use different treatment of patients salvianolate cause liver and kidney toxicity damage, still large prospective randomized controlled trials further study.
