Objective To discuss which drainage method is more efficient in treatment of choledocholithiasis with obstructive jaundice. Methods Compared the difference of serum total bilirubin,direct bilirubin, the variation of serum total bilirubin and direct bilirubin before and after drainage and daily biliary drainage by endoscopic nasobil-iary drainage (ENBD) and endoscopic nasobiliary drainage with continuous negative-pressure suction after three days. Results The daily biliary drainage about the patients by ENBD with continuous negative-pressure suction is much more effective than the patients by ENBD. The serum total bilirubin and direct bilirubin about the patients by ENBD with continuous negative-pressure suction is less than the patients by ENBD after three days. The variation of serum total bilirubin and direct bilirubin before and after drainage about the patients by ENBD with continuous neg-ative-pressure suction is more than the patients by ENBD. Conclusion The ENBD with continuous negative-pres-sure suction is more effective for choledocholithiasis with obstructive jaundice.

Objective To investigate the risk factors and predictors of poor outcome in full-term neonates with severe hyperbilirubinemia. Methods Data were retrospectively collected from 326 neonates with severe hyperbilirubinemia hospitalized between January 1, 2012 and December 31, 2012. Results A total of 326 full-term neonates with severe hyperbilirubinemia were included in this study (181 males and 145 females). The average gestational age was 39.12±1.17 weeks. Two hundred and sixty (260) cases were followed up successfully by phone while 66 cases were lost to follow-up. Infection (74.40%) and hemolytic disease (51.19%) were the main causes of severe hyperbilirubinemia. Multiple factors regression analysis found that threshold TSB was an independent risk factor of poor outcome (OR=2.02, 95%CI:1.13~3.62, P=0.018). The outcome of neonates with BIND scored between 0-6 had poor prognosis and some of them were reversible, and the outcome in those scored between 7-9 were of worse prognosis. Threshold TSB, USB and B/A ratio in group of poor outcome were signiifcantly higher than those in other groups and their area under the ROC curve evaluating the prognosis was 0.682, 0.671 and 0.698, respectively. With TSB at 474.5 μmol/L, UCB at 449.15 μmol/L and B/A at 0.923 mg/g, Youden index was the higest. The results of BAEP, OSE, MRI and NBNA were not signiifcantly different between groups with or without poor outcome. Conclusions Threshold TSB is an independent risk factor of poor outcome in full-term newborns with severe hyperbilirubinemia. BIND score is a very good predictor of outcome. TSB threshold, USB and B/A ratio are the predictors of outcome, but their diagnostic values are limited. NBNA, hearing screening and hyperintense globus pallidus on T1W1 in the acute phase of jaundice might not related with neurologic prognosis.

Objective To evaluate the treatment of advanced endometrial cancer with californium-252 brachytherapy. Methods 21 cases of endometrial cancers who had not received any treatment were diagnosed as in the stages Ⅰ～Ⅳ according to the criteria of FIGO. Treatment schedule included: 252Cf brachytherapy, 8～12Gy/fraction/week, the total dose of reference point A was 35～45 Gy and total dose of reference point F was 35～50Gy in three to four implant sessions. On the second day after 252Cf therapy, the whole pelvis was treated with 6MV X-ray external beam radiotherapy, 200 cGy per fraction, 4 times per week. The total dose of external beam radiotherapy was 45 to 50 Gy (the middle of pelvis was shielded with 4cm of lead), and the total treatment time was 5～6weeks. The recent therapeutic effect and complications were observed. Results The average time of complete tumor regression was 25 days, the local control rate was over 90%; the late radioactive complications of bladder and rectum was low during the 5-year follow-up period. Conclusions Combined californium-252 brachytherapy and high energy X-ray external beam radiotherapy may be safe and effective on advanced endometrial cancer.

Objective To assess the preventive effects of FK506 and Leflunomide (Lef) on islet xenograft acute rejection in rat-to-mouse models. Methods The islets of rat were transplanted under the kidney capsule of streptozotocin-induced diabetic mouse. The recipients were randomly divided into control group, un-treatment group, mono-therapy group and combination-therapy group. All immunosuppressants were administrated daily from 0 to 9 days. CD4 +\, CD8 + T-cell subsets and IL-2 were examined on the 5?th day after transplantation. Results Compared with un-treatment group, xenoislet survival could be significally prolonged in mono-therapy group. Combination-therapy of FK506 with Lef could significantly prolong the survival of xenoislet when compared with FK506 or Lef used alone. The number of CD4 + T-cells in mono-therapy group and combination-therapy group was much less than in un-treatment group. Conclusion Both FK506 and Lef can suppress proliferation of CD4 + T-cells and prevent or delay islet xenograft rejection.

Objective To assess the efficacy of different types of thymectomy for the treatment of myasthenia gravis(MG).Methods A retrospective analysis on 269 cases of MG,who were treated in our hospital from 1991 to 2006 by transsternal thymectomy(January 1991 to May 2002,n=161),thoracoscopic thymectomy(February 2002 to July 2005,n=67),or video-assisted thoracoscopic extended thymectomy(VATET,February 2005 to November 2006,n=41).Results The mean operation time of the transsternal group was significantly shorter than that in the other groups [transsternal group vs thoracoscopic and VATET groups:(97.5?17.5)min vs(130.3?31.5)min(q=12.991,P

Objective To evaluate the effect of tourniquet on incisional infection based on animal model,and evaluate the effect of ischemia preconditioning on incisional infection,so as to provide experimental basis for the ra-tional use of tourniquet in clinic.Methods 100 BALB/c mice were randomly divided into 4 groups,with 25 mice in each group.Group A:tourniquet+methicillin-resistant Staphylococcus aureus (MRSA)incisional infection;group B:ischemic preconditioning+ MRSA incisional infection ;group C :MRSA incisional infection;group D:blank control.The survival rates,temperature,routine blood testing,and change in soft tissue beside femoral incision were compared among 4 groups.Results During observation period ,the survival rate in group A was 68%,in group B,C,and D were all 100%,group A was lower than group B,C,and D (P <0.05).The temperature at each time point was significantly different among group A,B,and C (P <0.01 );temperature curves of 4 groups were significantly different (P <0.01 );except basal body temperature,temperature at the other time points among 4 groups were significantly different(all P <0.01);routine blood testing results (white blood cell count,total granu-locyte count,and total lymphocyte count)among 4 groups on the third,and seventh day were significantly different (all P <0.05);on the seventh day,routine blood testing results of 4 groups all returned to normal level,but group A was slightly higher than group B,C,and D.Section of epithelial tissue revealed that epithelial tissue in group A was not healed,inflammatory response of peripheral tissue was most serious;epithelial tissue in 10 mice in group B was healed,partial peripheral tissue revealed inflammatory response;epithelial tissue in 4 mice in group C was healed,most peripheral tissue revealed inflammatory response.Conclusion Mice incisional infection will be aggrava-ted by using lower limb tourniquet,incision healing and body function recovery time will be delayed,even lead to death.Ischemic preconditioning before making an incision model can reduce the severity of incisional infection,and shorten wound healing time.

Education to medical postgraduates is relatively special. Their study and research work have something to do with their clinical practice. Based on their technical training for thoracic surgery,postgraduates were demanded to follow up and instruct their patients on postoperative recovery from surgery. In this way,these postgraduates were trained not only in clinical practice but also in other aspects,such as communication techniques,how to take care of patients,professional moral education. Instruction to outpatients is helpful to cultivate post-graduates and promote their abilities in self-thinking,self-acknowledging,initiative,creation,and so on. Instruction to outpatients is an important way to bring up excellent medical postgraduates.

Infectious endophthalmitis refers to the acute suppurative inflammation of the uveal and retinal, with acute onset, severe symptoms, and poor prognosis.Early diagnosis and effective treatment is particularly important.Based on the way of intraocular infection, endophthalmitis can be divided into endogenous endophthalmitis and exogenous endophthalmitis.In the East Asian, liver abscess is the main source of endogenous endophthalmitis, and Klebsiella pneumoniae is the main pathogen.Liver abscess endophthalmitis is a serious cause of blindness caused by intraocular infection.A liver infection disseminated through hematogenous and the primary focus was hidden, which makes the disease was easy to be confused with immune related uveitis, causing high misdiagnosis rate, delaying the best time for diagnosis and treatment.In this article we reviewed the etiology, clinical features, diagnosis and treatment and prognosis of endogenous endophthalmitis caused by liver abscess.Clinicians should maintain a high index of suspicion to the endogenous endophthalmitis caused by liver abscess.
