Objective To study the diagnosis and treatment of choledocholithiasis in patients with low left and right posterior hepatic duct confluence.Methods Clinical data of 12 patients suffering from cholelithiasis with a low confluence of the left and right posterior hepatic ducts admitted between January 2000 to June 2013 were retrospectively analyzed.Results Of the 12 cases,the left and right posterior hepatic ducts joined between 2 cm below hilus hepatis and the superior border of the duodenum in 8 cases,below the superior border of the duodenum in 4 cases.Seven cases had a low confluence of the right and left hepatic ducts,and 5 cases had right posterior duct low confluence.As for bile duct stricture:the opening stricture at the junction of the right and left hepatic ducts were found in 4 cases,the opening stricture in the right hepatic ducts were found in 3 cases,the opening stricture of the left hepatic duct were found in 2 cases.There were left and right bile duct stones in 7 cases,right intrahepatic bile duct stones in 3 cases,left intrahepatic bile duct stones in 2 cases.Cystic duct joined the right hepatic duct in 5 cases,left hepatic duct in 2 cases.Seven cases with a low confluence of the right and left hepatic ducts were with double T tube drainage; five of low right hepatic duct confluence were treated by T tube drainage.The right posterior branch of hepatic ducts were injured in four cases and right hepatic duct was injured in one.Conclusions Low confluence of left and right posterior hepatic ducts often leads to misdiagnosis during surgery of cholelithiasis.Magnetic resonance cholangio-pancreatography or endoscopic retrograde cholangiopancreatography was helpful before cholecystectomy to avoid iatrogenic injury of biliary tract.

Objective: The aim of this study is to investigate the clinical factors in association with venous thromboembolism (VTE) in patients with lung cancer, and to provide evidence for prevention and therapy of VTE. Methods: Clinical information of 2 053 patients with lung cancer definitely diagnosed by cytology or pathology between July 2008 and June 2010 was retrospectively analyzed. VTE wasconfirmed by chest spiral computed tomography (CT), pulmonary arteriography and colorful Dopplerultrasound. The clinical factors including age, gender, pathological type, operation, clinical stage,body mass index, co-morbidity and platelet count as well as D -dimer, interleukin-1 (IL-1) and tumornecrosis factor (TNF) were considered as the potential VTE-related factors. Results: Of 2 053 patients,89 (4.34%) were confirmed with VTE. The incidence rates of VTE in patients with adenocarcinoma andnon-adenocarcinoma were 5.65% (58/1 027) and 3.02% (31/1 026), respectively, and the difference wasstatistically significant (P £?0.003). The incidence rate of VTE in stage I-III A lung cancer patients was significantly lower than that in stage IIIB-IV lung cancer patients [1.48% (10/677) vs 5.74% (79/1 376); P<0.001]. In patients with stage I-IIIA undergoing surgical operation or not, the incidence rates of VTE were 1.55% (10/645) and 0% (0/32), respectively (P=0.044). Significant difference of incidence rate of VTE was also found between the patients with and without co-morbidity [6.73% (56/832) vs 2.70% (33/ 1 221); P<0.001]. The incidence rates of VTE in patients with normal levels of platelet count, D -dimer,IL-1 and TNF were 3.72%, 0.31%, 2.44% and 3.27%, respectively; whereas, the incidence rates in patients with increased levels of these measurements were 6.26%, 19.91%, 10.26% and 7.74%, respectively; the differences between two groups were all significant (P<0.05). Logistic multivariant regression analysisrevealed that the clinical factors of adenocarcinoma, operation, co-morbidy and high levels of D-dimer,IL-1 and TNF in blood were associated with increased risk of VTE (P<0.05). Conclusion: Adenocarcinomais the most common pathological type in lung cancer patients with VTE. The risk factors of VTE include operation, co-morbidity and high levels of D -dimer, IL-1 and TNF in blood. Copyright© 2011 by TUMOR.

Objective To investigate the effects of inverse ratio ventilation with positive end expiratory pressure (PEEP) on pulmonary function and inflammatory cytokine in patients undergoing pulmonary lobectomy during one-lung ventilation.Methods Eighty patients with one-lung ventilation,52 males,28 females,aged 37-65 years,BMI 21-29 kg/m2,ASA grade Ⅱ,were randomly divided into inverse ratio ventilation (IRV) group and conventional ventilation (CV) group (n=40 each).Patients were all implemented into the program of general anesthesia,and ventilated with different modes.The IRV group were ventilated with a actual tidal volume (VT) of 7 ml/kg,respiratory rate of 12 breaths/min,I:E of 2:1,PEEP 5 cm H2O;in CV group with I:E of 1:2.Respiratory parameters were recorded at baseline (T0),5 min after anesthesia (T1),initiate of one-lung ventilation (T2),45 min of one-lung ventilation (T3) and the end of surgery (T4).Arterial blood was collected to analyze blood gas at T0 and T3 respectively.Meanwhile,oxygenation index was calculated.The concentrations of IL-6,IL-8 and IL-10 in bronchoalveolar lavage fluid (BALF) were measured with fiberoptic bronchoscope by enzyme-linked immunosorbent assay (ELISA).Results Compared with CV group,PaO2was significantly increased and levels of IL-6,IL-8 and IL-10 in BALF were significantly decreased at T3 in IRV group (P<0.05);Ppeak and Pplat were significantly decreased at T1-T4 in IRV group (P<0.05);PEEP,Pmean and CL at T1-T4 were significantly increased at T1-T4 in IRV group (P<0.05).Two cases (5.0%) of hypoxemia were found in CV group,one case (2.5%) of hypoxemia was found in IRV group,but there were no statistically significant differences in both groups.Two groups were not seen to complications such as delay,atelectasis and pneumothorax.Conclusion The oxygenation and hypoxemia were improved and inflammatory cytokine was released in patients with one-lung ventilation.

Objective To explore the differences of intelligence ，ability of social adaptation and behavior problems between patients of benign epilepsy childhood and those of normal controls .Methods Sixty children of benign epilepsy were investigated. Results The intelligence of children showed no significant differences between two groups ( P＞0.05), while the rate of ability of social adaptation among the children of benign epilepsy patients was less than that of nomal controls （P<0.01) . There were no significant differences in the total rate of behavior problems between two groups except that some factors were different . Conclusions We should create methods to enhance the ability of social adaptation in order to avoid the abnormal behavior when the children patients of benign epilepsy are treated by drugs.

Objective:To explore the diagnostic value of treadmill exercise test (TET)and its Duke score in menopa-usal female patients with coronary heart disease (CHD).Methods:A total of 102 menopausal female patients re-ceived TET and coronary angiography (CAG)examination.With CAG as control,accuracy indexes etc.of TET combined Duke score diagnosing coronary artery disease in these patients were compared and analyzed.Results:Compared with single application of TET or Duke score,there were significant rise in specificity (27.12% vs. 30.50% vs.44.44%),positive predictive value (47.56% vs.46.75% vs.54.55%),negative predictive value (80%vs.72% vs.90.91%)and accuracy (53.92% vs.52.94% vs.64.94%)diagnosing CHD by TET combined Duke score both positive and negative,P <0.05 all;but there was no significant difference in sensitivity,P >0.05 both. There was no significant difference in CHD diagnosis between single use of TET and Duke score,P >0.05 all.Con-clusion:False positive rate of treadmill exercise test is higher in menopausal women.Treadmill exercise test com-bined Duke score is helpful to improve specificity,positive predictive value,negative predictive value and accuracy of the test.

Objective To study the therapeutic effects and side effects of foscarnet in the treatment of active(IgG+,IgM+)and inactive(IgC+,IgM-)cytomegalovirus(CMV)infection after cadaver renal transplantation.Methods Forty-one cases of active cytomegalovirus infection and 22 of inactive cytomegalovirus were selected to receive foscarnet treatment.Besides,10 cases of inactive cytomegalovirus infection served as control group without receiving foscarnet.The usage of foscarnet was 40 mg/kg,iv.,2 ～3 weeks in the active stage,50 mg/kg,iv.,3～4 weeks in the inactive stage.Results Clinical symptoms of patients in the active stage were controlled,and serologic CMV IgG turned negative.Moreover,no positive infection was found after 3-month follow-up for those who received foscarnet.At the same time, 3 patients in the control group turned into active infection. Only one receiving foscarnet appeared urine volume cutting down temporarily,and the renal function had a reversible change;2 patients had skin red reaction.Conclusion Foscarnet could control CMV active infection quickly,markedly and firmly.and no recurrence was found during a 3-month follow-up.Foscarnet may protect the inactive patients from turning positive.And foscarnet had no obvious damage to the renal graft function and didn't interfere with the metabolism of blood calcium and cyclosporine A.Foscarnet is a safe and effective drug to treat CMV infection.
