1.Research progress of liver functional reserve
Journal of Clinical Surgery 2017;25(3):235-237
Liver functional reserve which functioned as the major evaluation factor for the tolerance of the liver surgery or the liver trauma had already been used wildly in preoperative evaluation for liver surgery.So far there were plenty of techniques for liver functional reserve.But each technique had its own advantages and disadvantages.This article briefly discussed the most wildly used techniques for liver functional reserve in preoperative evaluation.
2.Effect of 2,3,4′,5-Tetrahydroxystilbene-2 -O -beta -D-glucoside on the Proliferation of Pulmonary Artery Smooth Muscle Cells In-duced by Hypoxia
Journal of Medical Research 2015;44(10):151-154
Objective To investigate the effects of the 2,3,4′,5-Tetrahydroxystilbene -2-O-beta-D-glucoside on the prolif-eration of PASMCs induced by hypoxia , in orde to search new drugs for the treatment and prevention of hypoxic pulmonary vascular remod -eling.Methods 3%O2 hypoxia was used to induced the proliferation of PASMCs .After hypoxic and TSG treatment for 24h, cell growth was determined by cell counting kit -8 ( CCK-8 ) , cell cycle was analysed by flow cytometry , the mRNA expression of HIF -1αwas measured by quantitative real -time PCR, and the reactive oxygen species ( ROS) production was determined by the fluorescence micro-plate reader .Results TSG can block the proliferation of PASMCs through G 0/G1 to S phase of the cell cycle arrest without cell cytotoxic-ity.Further experiments showed that TSG blocking the proliferation of PASMCs was associated suppression the mRNA expression of HIF -1αand the production of intracellular ROS in hypoxia -stimulated-PASMCs.Conclusion TSG can inhibit the proliferation of pulmo-nary artery smooth muscle cells induced by hypoxia through suppression the mRNA expression of HIF -1αand the production of intracel-lular ROS.
3.The quality standard study of Huangqi-Changyu'an capsule Yutian Hospital of TCM of Hebei Province, Tangshan 064100, China
International Journal of Traditional Chinese Medicine 2015;(11):1015-1018
Objective To establish the quality standard of Huangqi-Changyu'an capsule. Method Thin layer chromatography was used to identify psoralen, evodia mtaecarpa, and nutmeg in Huangqi-changyu'an capsule. HPLC was used to determine the content of psoralen. A Hypeisil BDS C18 column(200 mm×4.6 mm,5 μm) was used with mobile phase consisted of acetonitrile-water (30:70) at the rate of 1 ml/min. The detection wavelength was set at 245nm with the column at room temperature. Results The liner range of psoralen was 3.572~53.58 μg/ml (r=0.999 9) with average recoveries of 99.04%, and the RSD was 0.8%. The liner range of isopsoralen was 3.796~56.94 μg/ml (r=0.999 9) with average recoveries of 99.20%, and the RSD was 0.6%. Conclusion This method is sentivive, accurate and rapid for the quality control of Huangqi-Changyu'an capsule.
4.The mechanism about the role of RhoA/ROCK singal pathway in portal hypertension
Chinese Journal of Hepatobiliary Surgery 2014;20(3):235-240
The hepatic portal system is a unique circulatory system that connects two systems of capillary beds ; one in the wall of the small intestine and spleen and the second in the sinusoidal area of the liver.Therefore,alterations in vasoreactivity (vasodilation and vasoconstriction) play a critical role in the pathophysiology of portal hypertension (PHT).The RhoA/ ROCK pathway exerts an important role in the Ca2+-independent mechanism in vascular smooth muscle (VSM).This mechanism not only modulates the constriction of intrahepatic small vessels and hepatic stellate cells (HSCs) but also effects the hyperdynamic circulation due to vascular hyporesponsiveness.Understanding the detailed mechanism and role of the RhoA/ROCK signal pathway in portal hypertension could be of great utility in providing a new target for portal hypertension therapy.
5.Cancer and venous thromboembolism
Journal of International Oncology 2012;39(6):455-458
Thrombosis disease is a common complication of cancer. Researches show that venous thromboembelism ( VTE ) can increase the mortality rate of patients with cancer.Tissue factor (TF) and cancer procoagulant (CP) and other pathological factors are related to VTE.VTE risk factors in cancer patients can be grouped into 3 general categories:patient-related factors,cancer-related factors and treatment-related factors.Assessment of risk factors and early prevention can reduce the incidence of VTE.Immediate treatment and chronic therapy should be performed immediately after the diagnosis of VTE.
6.Treatment of infections in patients with primary immunodeficiency disease
Chinese Pediatric Emergency Medicine 2013;20(3):240-243
Primary immunodeficiency disease (PID) is a heterogeneous group of congenital disorders of the immune system.The impaired immune response is caused by defect of immune active cells and moleculars,which results in increased susceptibility to pathogens.Recurrent infection is the predominant presenting complaint for patients with PID.Early diagnosis,immunoglobulin replacement therapy,antimicrobial treatment,haematopoietic stem cell transplantation and gene therapy,genetic conselling and prenatal diagnosis will help to prevent and control infections in patients with PID.In addition,we should strengthen the education of paediatricians,improve awareness about PID and collaboration across different centers to advance the diagnosis and management of PID in China and save the life of patients at the maximum limit.
7.Treatment advances in early-stage primary systemic anaplastic large cell lymphoma
Cancer Research and Clinic 2016;28(7):493-497
Primary systemic anaplastic large cell lymphoma (ALCL) is a subtype of rare and heterogeneous clinical entity, extremely rare in early stage of disease. There is no standard treatment yet. Based on retrospective studies, systematic chemotherapy followed by involved field radiation after chemotherapy is the mainstay of treatment. The role of radiotherapy in the treatment of early stage ALCL remains unclear due to lack of prospective studies. So do the optimal chemotherapy regimens and hematopoietic stem cell transplantation. The paper will review these issues.

Chinese Journal of Current Advances in General Surgery 2004;0(06):-
Objective: To summarize the clinical application of reservation of partial duode- num in pancreaticoduodenectomy. Methods: 21 patients of pancreaticoduodenectomy were per- formed with partial duodenum, trans-ligment of Treits and upper-jejunum reservation from June 2000 to June 2005 in our hospital and the clinical data were retrospectively analyzed. Results: There was no death in operation; 2 cases with incision split due to infection after surgery were cured by secondary suture; the rest were discharged from hospital from hospital successfully; a mean period of in-hospital was 21 days, without bile leakage or pancreatic leakage. Follow-up period was from sixmonths to five years, and there were 18 cases with 1-year survival (85.7%), 14 cases with 2 - year survival(66.6%) and 3 cases with 3-year(14.2%). Condusion: Reservation of partial duodenum can reduce trauma caused by extensive anatomy and shorten operation time.
