1.Molecular diagnosis of intrahepatic cholangiocarcinoma
International Journal of Surgery 2016;43(10):716-720
Intrahepatic cholangiocarcinomas (ICCA) are primary intrahepatic malignancies originating from biliary epithelia.While both hepatocellular cancer and ICCA can present as mass lesions within the liver,these cancers are distinct in their morphology,etiology,pathology,natural history and response to therapy.There is a need for accurate and sensitive molecular markers for the diagnosis of ICCA.Recent advances in elucidating molecular and genetic characteristics of ICCA offer the potential of molecular-based diagnosis of ICCA.Specific genetic mutations of IDH1/2,BAP1,p53,and KRAS,FGFR gene fusions and alterations in microRNA have all been described in ICCA.Although there are no accurate serum or biliary biomarkers currently available for diagnosis of ICCA,several potential candidates have been identified.Knowledge of specific genetic or molecular abnormalities offers potential for individualized approaches for the treatment of patients with ICCA in the future.

Journal of Shanghai Jiaotong University(Medical Science) 2006;0(02):-
Objective To investigate the changes of psychological state and family environment of the patients with neurosis (including depression and anxiety) in the process of treatment. Methods The Hamilton depression scale (HAMD), Hamilton anxiety scale(HAMA), self-rating depression scale(SDS), self-rating anxiety scale(SAS), family environment scale(FES), and family adaptability and cohesion scale(FACESⅡ-CV) were used to evaluate the changes of psychological state and family relationship in the process of treatment among patients with depression and anxiety hospitalized in general hospitals (n=45) and their family members (n=45). Results Before intervention, values of HAMD, HAMA, SDS and SAS in patients were higher than normal ones, and were in line with the corresponding diagnostic criteria. After psychological intervention and medication for 2 to 3 months, symptoms such as depression and anxiety were improved significantly, and values of the above scales were within normal ranges. Besides, there was also significant improvement in FES and FACESⅡ-CV after intervention among the patients. All the values of the family members were in the normal ranges before intervention, however, significantly positive changes were observed after intervention. Conclusion With the improvement in depression and anxiety after intervention among patients, the psychological pressure of family members is released, and family relationship is partially restored. The rehabilitation of patients plays an important role in the restoration of family function.

Objective To evaluate urodynamic diagnosis of intrinsic sphincter deficiency (ISD) in female stress urinary incontinence. Methods Leak-point pressures (LPP) and maximum urethra close pressures (MUCP) were detected in 30 patients with female stress urinary incontinence,among whom there were 11 cases with type Ⅲ,19 type Ⅱ/Ⅲ. Results Of type Ⅲ incontinence the LPP was less than 50 cmH 2O in 10 out of 11 and in 17 out of 19 type Ⅱ/Ⅲ incontinence the LPP 50~100 cmH 2O ( P
6.MSCT-guided percutaneous transthoracic biopsy of lung lesions by using BARD gun: Its clinical application
Journal of Interventional Radiology 1992;0(01):-
Objective To discuss the clinical application of MSCT-guided BARD gun biopsy in diagnosing pulmonary lesions. Methods Under MSCT-guidance percutaneous transthoracic biopsy of lung with BARD gun was performed in 68 patients with pulmonary lesions. Results All the procedures were well performed with the technical successful rate of 100%. The final diagnosis was based on the pathological findings or clinical follow-up observation. The accuracy of the qualitative diagnosis was 94.1%. Of 68 patients, squamous cell carcinoma was found in 30, adenocarcinoma in 21, metastases in 7, inflammatory pseudotumor in 3, lung abscess in 2, and tuberculosis in one. The false-negative rate in making diagnosis was 5.9%. The complication occurrence was 8.8%. Conclusion BARD gun has the advantage of making coaxial- multipoint biopsy. With the help of MSCT-guidance and the full use of the operating advantage of BARD gun, this technique is safe and reliable, with higher accuracy and less complications.

Objective To study the clinical effects of methylenetetrahydrofolate reductase(MTHFR) C677T gene mutation on mild vascular cognitive impairment(VCI)in patients with cerebral infarction.Methods The prospective study was conducted in 180 patients with atherosclerotic acute cerebral infarction hospitalized from June 2015 to May 2016.180 patients were divided into normal homocysteine(Hcy)group (Hcy 5.46~16.20 μmol / L,n=130)and high Hcy group(Hcy>16.20 μmol / L,n=50).MTHFR C677T genotypes were detected by polymerase chain reaction-restriction endonuclease fragment length polymorphism.The VCI state and risk factors for VCI were analyzed with Montreal Cognitive Assessment scale(MoCA)and Mini Mental State Examination(MMSE)score in patients with acute cerebral infarction on admission and 14 days,30 days and 90 days after admission.Results MMSE and MoCA scores at 14 days,30 days,90 days after admission were lower in high Hcy group than in normal Hcy group(P<0.05 or P<0.01).MMSE and MoCA scores were lower in T/T genotype than in C/C genotype(P<0.05)at 14 day after admission,and lower in C/T genotype than in C/C genotype at 30 day and 90 day follow up(P<0.05or P<0.01).Logistic regression analysis showed that Hcy may be independent risk factors for mild VCI(OR =1.274,95%CI:1.027~1.264,P=0.018).Conclusions MTHFR C677T gene mutations may cause hyper-homocysteinemia,and promote the emergence of VCI in patients with cerebral infarction.MTHFR C677T gene mutations may be a genetic susceptibility factor for VCL

Objective To evaluate MRI in diagnosis and follow-up of Achilles tendon rupture. Methods From April 2003 to May 2005, 24 cases of closed Achilles tendon rupture were examined in our department with MRI. It was performed through sagittal T1WI, T2WI, GE-STIR and axial TME imaging. Four cases were followed up with MRI after 4 to 8 weeks. Results MRI could determinate the severity and exact location of Achilles tendon rupture by demonstrating signal changes of Achilles tendon. In this series, complete rupture of Achilles tendon mostly occurred at the median part, with augmentation and high signal on T2WI. MRI demonstrated high signal on T2WI in partial rupture of Achilles tendon. The signal intensity in the four cases followed up by MRI was shown to decrease. Conclusion MRI is a valuable tool for clinical diagnosis and follow-up of Achilles tendon, because it provides enough information through signal changes at the tendon.

Objective:To compare the efficacy, safety and economics of zhibituo and lovastatin in the treatment of hyperlipidemia. Methods:Searching medical references were done, The qualified results of clinical trials were Meta-analysed for evaluating the efficacy of zhibituo comparing with lovastatin. The characters of zhibituo and lovastatin were also compared through scoring by senior physicians. Results:The results of Meta-analysis showed that zhibituo had stronger effects on lowering TG and elevating HDL.It had less severe ADR for old people and cost less than lovastatin. The results of physicians-scoring records showed no significant difference between these two drugs. Conclusion:Zhibituo and lovastatin both are potential lipid-lowering agents. zhibituo is safer and more cost-effective for old people with mild to moderate elevated serum LDL level.
