1.Relations of matrix metalloproteinases and tumor microenvironment
Journal of International Oncology 2008;35(11):810-812
Matrix metalloproteases(MMPs)and tissue inhibitors of matrix metalloproteases(TIMPs) have a co-regulation of changes of the extraeellular matrix(ECM).MMPs can control the proteases which are related to the process of tumor development.Moreover,MMPs,produced by host cells including inflammatory ceUs,endothelial cells,pericytes and fibroblasts have a positive or negative correlation with tumor formation.
3.Two regimes of transient intensive insulin therapy in newly diagnosed type 2 diabetic patients
Chinese Journal of General Practitioners 2008;7(2):86-89
Objective To evaluate two regimes of transient intensive insulin therapy in newly diagnosed type 2 diabetic patients with severe hyperglycemia.Methods Sixty-eight newly diagnosed type 2 diabetic patients with fasting plasma glucose(FPG)≥10.0 mmol/L and glycated hemoglobin A1c (HbA1c)≥8.0%were randomized to either cantinuous subcutaneous insulin infusion(CSII)group or multiple daily injection(MDI)group.Glycemic control,daily dose of insulin,body mass index(BMI),the mean area under the insulin curve(AUC),β-cell function(HOMA-β)and insulin resistence(HOMA-IR) were compared before and after treatment.Results There were no significant differences between two groups in days reaching glycemic control and BMI.The maximal insulin dose for glycemic control in CSII group was(0.53±0.06)U·kg-1·d-1 and that in MDI group was(0.71±0.04)U·kg-1·d-1(t= 11.100,P<0.01).After CSII and MDI treatment,HOMA-β and the mean AUC of insulin were significantly increased(P<0.01),but there was no significant difference between two groups(P>0.05).No significant changes in HOMA-IR were observed before and after treatment or between two groups.There were no severe hypoglycemic episodes in two groups and mild hypoglycemic episodes were 0.34%(13/3806)in CSII group and 1.09%(44/4045)in MDI group.Conclusions The excellent glycemic control can be reached by short.terra CSII and MDI treatment in newly diagnosed type 2 diabetic patients with severe hyperglycemia.Lower insulin dose and less mild hypoglycemic episodes seem to be the advantage of CSII regime than MDI regime.β-cell function can be dramatically improved in both therapy regimes.
4.Primary intestinal lymphangiectasia
International Journal of Pediatrics 2011;38(1):4-6
Primary intestinal lymphangiectasia is a rare disease, which is characterized by the obstruction of lymphatic return, dilated lymphatics and distorted structure of villi. Lymph fluid leaks into the small bowel lumen as a result of the obstruction of lymphatics and elevated pressure of lymphatics, and leads to malabsorption and loss of proteins. The causes and pathogenesis of PIL are not clear, hut the abnormal immunologic mechanism has got people's attention. Recently, the endoscopic technique has been improved, and the diagnosis rate of PIL has increased obviously. Antisecosis is the basic and effective treatment, especially for children.
5.Correlation between the Rorschach inkblot method and 16 personality factor questionnaire
Chinese Journal of Tissue Engineering Research 2006;10(42):191-193
AIM:To investigate the validity of Rorschach inkblot method (RIM) in personality research by calculating the correlation of RIM with 16 personality factor questionnaire (16 PF).METHODS: Totally 70 undergraduates participated in the examination with RIM and 16 PF, then the correlations of all the variables of two measuring techniques were calculated. Standard score of comprehensive system was used in RIM.RESULTS: Some important Rorschach variables were correlated significantly with 16PF factors, and the correlations are consistent with their meaning. Some variables correlated with 16PF factors but were irrelevant in meaning.CONCLUSION: The results support the validity of RIM in personality study, and they also demonstrate that comprehensive system cannot well annotate RIM, but the meaning of some variables should be further researched.
6.Research progress on molecular pathology of cholangiocarcinoma
Chinese Journal of Hepatobiliary Surgery 2011;17(2):171-174
The early diagnosis of cholangiocarcinoma is difficult, and the prognosis is poor. The molecular mechanisms underlying the development, growth and metastatic spread of biliary tract cancers are still unclear. The increase in worldwide incidence and mortality of cholangiocarcinoma justifies the impellent need to clarify the intracellular mechanisms triggering the malignant transformation of the biliary epithelium and growth of biliary malignancies. A more complete characterization of the molecular pathology of bile duct cancers could lead to the identification of valid targets for diagnosis and therapy of these devastating malignancies. This review describes the scientific progress made over the past years with regard to the understanding of the molecular processes of cholangiocarcinogenesis.
7.Vascular endothelial growth factor and remedial angiogenesis
International Journal of Surgery 2008;35(10):675-678
Vascular endothelial growth factor (VEGF) is the endothelial cell-specific mitogen, facili-tates endothelial cell proliferation, increases vascular permeability and accelerates the formation of new blood vessels role. Angiogenesis is an important physiological and pathological significance of the process. In the human wound healing, inflammation, organ regeneration and tumor growth and metastasis, vascular prolifer-ative diseases, angiogenesis is an important role. Therapeutic angiogenesis is the use of inducible factor or vascular endothelial progenitor ceils, simulates in vivo angiogenesis mechanism, promotes angiogenesis and improves the collateral circulation. In this paper, VEGF and therapeutic ansiogenesis research progress were reviewed.
8.The clinical research of bevacizumab combined with FOLFIRI as second-line treatment in advanced colorectal cancer
Chinese Journal of Postgraduates of Medicine 2012;(35):29-31
Objective To evaluate the efficacy and safety ofbevacizumab combined with FOLFIRI regimen as second-line treatment in advanced colorectal cancer.Methods Sixty-five advanced colorectal cancer patients previously treated with oxaliplatin were divided into test group(33 patients) and control group (32 patients) by random digits table method.The patients in test group received bevacizumab combined with FOLFIRI regimen chemotherapy.The patients in control group received FOLFIRI regimen chemotherapy only.The therapeutic effect was evaluated every 4 cycles.Results In test group,1 patient received complete remission,9 patients had partial remission,the rate of efficacy was 30.3% (10/33).In control group,non patient had complete remission,3 patients received partial remission,the rate of efficacy was 9.4% (3/32).The rate of efficacy between two groups had significant difference (x2 =4.45,P =0.035).The median duration of survival was 13.0 months in test group,and 10.3 months in control group(HR =0.58,P=0.038).The median progression-free survival duration was 7.5 months in test group,and 4.4 months in control group (HR =0.45,P =0.003).The median treatment cycle was 12 cycles in test group and 8 cycles in control group.The rate of Ⅲ/Ⅳ grade adverse events in test group was higher than that in control group[72.7%(24/33) vs.46.9% (15/32)] (P < 0.05).None of these events led to death during the study.Conclusions Bevacizumab combined with FOLFIRI as second-line treatment in advanced colorectal cancer can improve the total remission rate,and prolong the progression-free survival duration and total survival duration with an acceptable adverse reaction.

10.Patient satisfaction following hospital-community continuity medical care in day surgery unit
Chinese Journal of Practical Nursing 2014;30(13):10-13
Objective To identify the patient satisfaction on follow-up service from the community health service (CHS) or West China hospital (WCH) and to compare the patient satisfaction on follow-up service from CHS and WCH.Methods A cross-sectional survey was used in this study to identify the patient satisfaction on day surgery.The questionnaires were self-made through literature review.Purposive sampling was used in collecting the data.Results Totally 758 qualified questionnaires were collected.The proportions of qualified questionnaires were 96.3%.Respectively,79.3% of patients were completely satisfied with follow-up service from WCH,19.3% of patients were partly satisfied,and 1.4% of patients were completely dissatisfied.66.7% of patients were completely satisfied with follow-up service from CHS,33.3% of patients were partly satisfied with follow-up service from CHS,and no objects were completely dissatisfied.Conclusions Patient satisfaction on follow-up services from WCH was higher than CHS.It is essential to enhance follow-up services from CHS.
