Objective To study the therapeutic value of a second ERCP for the patients with failure of pre-cut ERCP.Methods A total of 167 cases of pre-cut ERCP failure were recruited to the study,among which 109 cases were diagnosed as common bile duct stones and/or benign papillary stenosis,and 58 cases as biliopancreatic lesion.ERCP failed with standard intubation for more than 20 minutes,even with pre-cut or fenestration.A second ERCP was preformed after rest of 3-5 days.The position sequence of intubation for most patients was horizontal,the front and rear.Results The success rate was 79.6％ (133 cases) for the patients with a second ERCP,85 patients received the procedures via the horizontal intubation,36 via anterior,and 12 via posterior intubation.The treatments were performed after successful completion of the endoscopic cannulation.One patient had retroperitoneal infection with duodenal perforation,another patient had severe pancreatitis,who were cured by the intervention methods.Conclusion The success rate of a second ERCP is high with proficient intubation skills.

Objective To explore the clinical application of the expression of LOXL2 mRNA and Tenascin-C mRNA in tissues for the disease with the bile duct cancer.Methods The serum and clinical data in 35 cases of patients with the bile duct cancer (cancer group) and 28 cases of patients with normal bile duct tissue (control group) were collected,used the real-time fluorescent quantitative PCR (real-time-PCR,RT-PCR) technology to detect the expression of LOXL2 mRNA and TenascinC mRNA in tissues toobserve the relationship between the changes and the bile duct cancer for the two markers.Results The expression of LOXL2 mRNA and Tenascin-C mRNA in tissues in the cancer group were 1.27±0.18 and 1.39±0.19,which of ones in the control group were 0.20±0.06 and 0.23±0.06.In the cancer group,the expression of LOXL2 mRNA and Tenascin-C mRNA in tissues respectively with comparision to those in the control group were significantly higher,the differences had statistical significance(t=52.18,56.87,P＜0.01),which of ones in the cancer group was positively related (r=0.687,P＜0.01).Conclution The expression of LOXL2 mRNA and Tenascin-C mRNA in tissues may be a molecular targets for the disease with the bile duct cancer in the early diagnosis and judgment of progression in the courses of this disease.

Obesity is a rapidly growing international health problem. The association of fat mass and obesity associated(FTO) gene and obesity is becoming the hot topic in the gene research. FTO is a member of the nonheme dioxygenase [Fe(Ⅱ) and 2-oxoglutarate-dependent dioxygenases]superfamily. FTO levels in the brain,especially in the hypothalamus,participate in the central control of food intake. The mutation of FTO gene accentuates body mass index,hip circumference and total weight,leading to obesity.

BACKGROUND: Cardiac reserve indicators obtained under quiescent condition are used as evaluating index for cardiac reserve functions. However, most important aspect of cardiac dysfunction in heart failure is not the depressed cardiac performance noted at basal resting states, but rather the loss of cardiac reserve. OBJECTIVE: To develop a data processing and information management system for detecting cardiac reserve indicator with the widely used B mode ultrasound instrument in the ultrasonography field, and to provide guidance for B mode ultrasound instrument perfection. METHODS: General B mode ultrasound instrument as peripherals was connected with the pc by image acquisition card; ultrasound heart image diagnosis and management system including professional heart image acquisition and process and perfect data bank was develop. RESULTS AND CONCLUSION: An efficient and flexible mini picture archiving and communication system system was achieved, which realized image enhancement, geometric parameter measuring, convenient diagnosis report output, archive management and print function. Results demonstrated that with the powerful data process ability of PC, the system could improve the performance of the traditional ultrasound instrument in detecting cardiac reserve, which provide a powerful support for the further study.

Objective　To determine the sensitivity and specificity of using the computer-photoscreener and non-cycloplegic retinoscopy in the detection of amblyopiogenic factors in nine to fifty months old infants.Methods　Three hundred children whose ages range from nine to fifty months were screened with the computer-photoscreener and non-cycloplegic retinoscopy. With a masked standardized clinical assessment as the standard, an overall comparison of the results obtained with the two techniques revealed a sensitivity and specificity. Photoscreen images on the computer monitor screen were reviewed and analyzed immediately by two independent observers for indicators of amblyopiogenic risk factors. Simultaneously, the results were compared to the findings of a full ophthalmologic examination.Results　The computer-photoscreener revealed a sensitivity of 94.2% and specificity of 90.1%, and the non-cycloplegic retinocopy revealed a sensitivity of 85.7% and specificity of 81.1% for the detection of amblyopiogenic risk factors, including hyperopia (+2.75 D or more), myopia (-1.50 D or more), astigmatism (2.00 D or more),anisometropia (2.00 D or more), ocular misalignment (5 degrees or more), and media opacity (1.5mm or more). Conclusion　The computer-photoscreener offers an opportunity to identify problems that limit vision, and could provide a feasible and sufficiently reliable screening technique in infants and preschool children who can be screened successfully for amblyopiogenic risk factors.

Glioma is the most common form of brain cancer. Despite recent advances in the treatment of solid tumors, there are few effective treatments for malignant gliomas due to its infiltrative nature. It has important significance to improve the treatment of glioma through in-depth understanding the intracerebral metabolic characteristics and pharmacokinetics of chemotherapeutics. Brain microdialysis (B-MD), an effective method to monitor central nervous system anticancer drug disposition, conditions of drugs through the blood-brain barrier, basic pathophysiologic metabolism, bioactive compounds and the changes of neurotransmitter in brain, provides the unique opportunity to allow the simultaneous determination of unbound concentrations of drugs in several tissues, and directly measure gliomas biochemistry continuously. B-MD has been able to monitor the change of brain drugs, metabolites and neurotransmitters, dynamic analysis of the drug concentration and pharmacological effect after administration, pharmacodynamic interaction between drugs, receptor mechanism of drug transport, as well as feedback information of internal environment. B-MD is expected to provide reference for clinical individual chemotherapy of glioma, but also provide powerful tools for the evaluation of new anticancer drugs in vivo. In this review, a comprehensive overview of B-MD for studies on glioma is elucidated with special emphasis on its application to neurochemistry and pharmacokinetic studies.

Objective To investigate the dosimetric characteristics of hippocampal?avoidance prophylactic cranial irradiation ( HA?PCI ) in fixed?field intensity?modulated radiotherapy ( IMRT ) and volumetric modulated arc therapy ( VMAT) and the feasibility and risks of hippocampal avoidance. Methods Prophylactic cranial irradiation (PCI) was performed for 16 patients with localized small cell lung cancer ( SCLC) who were treated in our hospital from January to August, 2014, and achieved complete response ( CR) after chemoradiotherapy, with a prescribed dose of 25 Gy in 10 fractions. CT localization image was fused with brain MRI image to contour the hippocampus on the fused image, and the boundary of the hippocampus was extended 5 mm outward to form the area for reduced dose. IMRT and VMAT plans with hippocampal avoidance were developed separately, and the dose distribution in the whole brain, the hippocampus, and the 5?mm area outside the hippocampus was evaluated for these two plans. Independent?samples t test was applied to evaluate the difference between the two groups. Results The mean hippocampal volume in the 16 patients was 2. 76 cm3 ( range 2. 56 ?3. 01 cm3 ) . The mean radiation dose ( Dmean ) in the hippocampus during IMRT and VMAT was 9. 04± 0. 20 Gy and 10. 32± 0. 28 Gy, respectively, reduced by 66. 0% and 61. 2%, respectively, compared with the prescribed dose ( P=0. 55);Dmean in the area for reduced dose during IMRT and VMAT was 13. 57± 0. 90 Gy and 14. 86± 0. 60 Gy, respectively, reduced by 49. 0% and 44. 1%, respectively, compared with the prescribed dose (P=0. 88). Conclusions HA?PCI in IMRT and VMAT meets the clinical requirements, and can reduce the dose in the hippocampus while ensuring the whole?brain radiation dose, and therefore can be applied in PCI and provide a technical support to protect the patient’ s neurocognitive function.
