This paper reported twenty-two cases of residual biliary duct stones.Because of biliary duct stenosis of stone impaction,the intrahepatic duct could not show by routine cholangiography through T-tube. We inserted a nylon cathetr lmm in diamenter into the selective biliary duct,and per- formed cholangiography through the catheter.The results were satisfactory in 20 of the 22 pa- tients. In the patients with large stones in the intrahepatic duct,the stone-dissolving liquid was instilled through a catheter which was kept in the selective duct.Finally,the stones fragmentated and were removed out successfully.

It is reported here that removal of residual stones and choledochofiberscopy through T-tube fistula were peformed on 512 patients. The removal procdeure followed by complica- tions, including fever (19 cases), hemorrhage (11 cases), fistulation between T-tube fistula and duodenum (6 cases), false passage formed by damage to the fistula (4 cases) and gallstones falling into false passage and being difficult to remove (2 cases) . The compli- cations with exception of the gallstones falling into false passage were adjusted after antibiotic treatment, coagulant drip by inserting a catheter and false passage drainge, respectively. The opening of T-tube fistula did not heal following remval of residual stones after Roux-en-y in two patients whose wounds only healed after suturing the intestinal wall and abdominal wall by reoperation. The causes, prevention and treatment of complications Were discussed in this papar.

Based on the current guidelines and research progress of severe acute respiratory symptom coronavirus 2(SARS-CoV-2) vaccines in various countries,this review summarized the research progress on non-clinical safety evaluation of SARS-CoV-2 vaccines by referring to the guidelines and relevant literatures over the world,in order to provide a reference for non-clinical research of SARS-CoV-2 vaccines.

Objective To explore the clinical significance of changes of serum.IL-6,IL-18 and C-reactive protein(CRP) in patients with hypoxic ischemic encephalopathy (HIE).Methods Serum IL-6,IL-18 and CRP levels were measured by ELISA and immunity turbidimetry respectively in 100 patients with HIE and 100 health control.Results The HIE group serum IL-6,IL-18 and CRP levels were higher than the healthy control group,and Serum levels of IL-6,IL-18 and CRP increased when the clinical manifestation gradually increased.The CRP were positive correlation with serum levels of IL-6 and IL-18(r=0.663,0.725,all P<0.01).and the serum level of IL-6is positive correlation with IL-18(r=0.783,all P<0.01).Conclusion The serum IL-6,IL-18 and CRP may play an important role in the development process of HIE.Which were correlate to the severity of the disease and clinical change,measurements of their serum concentrations may help to predict these pathogenetic condition and prognosis criterion of the disease.

Chemotherapy induced thrombocytopenia( CIT) is a major dose-limiting hematologic toxicity with cancer patients.Aside from bleeding risk, thrombocytopenia limits chemotherapy doses and frequencies. While platelet transfusion is remain the elementary method for CIT,administration of platelet growth factors,such as recombinant human interleukin-11(rhIL-11),recombinant human thrombopoietin(rhTPO)and thrombopoie-tin receptor agonist(TPO-RA),are convenient and effective platelet-support strategies for patients receiving myelosuppressive chemotherapy.In addition,other cytokines and proximal splenic artery embolization( PSAE) are expected to be new clinical therapies.In this review,we summarize the existing data and approaches in the treat-ment progress of CIT.

Objective To investigate the clinicopathological significance of upregulated NQO 1 protein expression in uterine cervix carcinoma ( UCC) .Methods Immunohistochemical staining was performed on paraf-fin-embedded UCC specimens from 123 patients.Disease-free survival(DFS)and overall survival(OS)rates for all cervical UCC patients were calculated using the Kaplan -Meier method ,and univariate or multivariate analyses were performed using the Cox proportional hazards regression model .Results The NQO1 protein showed a main-ly cytoplasmic staining pattern in cervical cancer cells ,and the strongly positive rate of NQO 1 was significantly higher in UCC.High-level NQO1 was closely associated with poor differentiation ,late-stage,lymph node metas-tasis and high-risk for HPV infection.Additionally,high-level NQO1 was associated with lower DFS and OS rates .Furthermore ,Cox analysis revealed that NQO 1 expression emerged as a significant independent hazard factor for DFS rate in patients with UCC .Conclusion NQO1 overexpression might be an independent biomarker for prognostic evaluation of UCCs .

Objectives To explore the ultrasonic features in the differential diagnosis of thyroid multiple nodules with thyroid carcinoma and summarize the causes of misdiagnosis,and to improve the accuracy of ultrasonic diagnosis of thyroid carcinoma.Methods The ultrasound images from the 40 patients with thyroid carcinoma were selected,whose diagnosis of thyroid carcinoma was confirmed by the pathological examinations after surgery but misdiagnosed or not identified by ultrasound examination.These ultrasound images were retrospectively analyzed through observing the carcinomatous nodules in size,aspect ratio,shape,border,envelope,internal echo,calcification characteristics,posterior echo,acoustic halo,the distribution of blood flow,and the relationship with thyroid capsule and anterior organization,whether to transfer to neck or spraclavicular lymph nodes,and the performance of elasticity imaging,and then these features were compared with the ultrasonic features of the benign thyroid nodules.Results The ultrasonic features of thyroid multiple nodules with thyroid carcinoma were complicated and each nodule should be observed and analyzed individually.The ultrasonic features of carcinomatous nodules were:(1) irregnlar shape,(2)aspect ratio ≥ 1,(3)unclear border,(4)no capsule,(5)heterogeneous hypo echo inside of the carcinomatous nodules,(6)scattered distribution of clustered microcalcifications,(7)incomplete acoustic halo or absent,(8)blood supply to the centrality inside of the carcinomatous nodules,(9)invaded thyroid capsule and anterior organizations,(10)transformation to neck or supraclavicular lymph nodes in the minority of patients,(11) elasticity imaging score of 3 ～ 5.Conclusions It is quite difficult to identify the ultrasonic features of thyroid multiple nodules with thyroid carcinoma and it is with high misdiagnosis rate.A comprehensive analysis of sonographic features is essential in clinical practices,and it will contribute to improving the accuracy of the ultrasonic diagnosis of thyroid multiple nodules with thyroid carcinoma.

Objective To explore the drug fast mechanism on carbapenems of Acinetobacter baumannii,it is important for clinicians to choose appropriate antibiotics.Methods The influence of active efflux inhibitors carbonyl cyanide m -chlorophenylhydrazone (CCCP)on minimal inhibitory concentration (MIC)of Acinetobacter baumannii to imipenem(IMP)was measured by agar dilution method.Results At the concentration of 10mg/L,CCCP had obvi-ously effects on carbapenems MICs,the rate of resistance of imipenem decreased from 64.39% to 34.38%.In vitro CCCP enhanced the activities of imipenem.Efflux mechanism existed not only in IMP resistant strains,but also in IMP sensitive strains.But the affection of CCCP against IMP resistant strains was much stronger than that of IMP suscepti-ble strains.Conclusion Efflux pump may be one of the main mechanisms of Acinetobacter baumannii resistance to IMP,while efflux pump inhibitors may partly reduce the resistance.
