1.Expression of Inducible Nitric Oxide Synthase and NF-κ Bp65 in Patients with Psoriasis Vulgaris and Their Clinical Significance
Chinese Journal of Dermatology 2001;34(2):103-104
Objective To investigate the internal relationship between the expression of inducible nitric oxide synthase (iNOS) and the activation of NF-κ Bp65 in the skin of patients with psoriasis vulgaris(PV) and their roles in the pathogenesis of PV.Methods The expression and distribution of iNOS and NF-κ Bp65 were studied by in situ hybridization and immunohistochemistry in 20 patients with PV and 12 healthy controls.The severity of PV was assessed by Psoriasis and Severity Index(PASI) score.Results ① The expression of both iNOS mRNA and protein was significantly higher in lesional epidermis than those in non-lesional epidermis and epidermis of the controls (P<0.01).Weak exprssion of iNOS mRNA was found in basal cell layer in a small number of healthy controls, however, strong expression was observed in entire basal cell layer and focal parts of prickle cell layer in all PV epidermis.② There was significantly positive correlation between iNOS and NF-κ Bp65 protein expression in lesional epidermis (P< 0.01).③ There was significantly positive correlation between the level of expression of iNOS mRNA in lesional epidermis and PASI score of patients (P< 0.01).Conclusions The expression of iNOS and NF-κ Bp65 is markedly increased in lesional epidermis of patient with PV.The activation of NF-κ B probably takes part in the pathogenesis of PV.High-level expression of iNOS may be due to the activation of NF-κ B.
2.Updates in the research of laparoscopic splenic hilar lymphadectomy for upper-third gastric cancer
Chinese Journal of Digestive Surgery 2014;13(12):991-994
Laparoscopic surgery for upper-third gastric cancer has gradually been accepted by experienced surgeons as the mature of this technique.Different from the standardized and programmed D2 lymph node dissection in Laparoscopy-assisted Billroth Ⅰ gastrectomy,the indications and methods for laparoscopic splenic hilar lymphadectomy in the upper-third gastric cancer remains controversial.Unsolved problems include joint organs resection,appropriate surgical approach selection and variable vascular anatomy of the splenic hilum.Meanwhile,the long-term efficacy and safety of laparoscopic splenic hilar lymphadectomy for the upper-third gastric surgery need to be confirmed by evidence-based medical trials.With the advance of the theory and clinical practice,laparoscopic splenic hilar lymph node dissection will continue to progress.
3.Social Factors Analysis of the Absence of Professional Ethics among Accountants
Chinese Medical Ethics 1996;0(01):-
As the repeated emergence of accounting communication distortion and criminal behaviors among accounts,the absence of accounts′ professional ethics is drawing increasing attention from the general public.The professional ethics absence is partially related to the imperfect self-discipline of accountants.However,self-discipline by its own can never solve the absence of accounts′ professional ethics to some extent.Certain social factors are also responsible,which are analyzed in this thesis,aiming to provide a welcoming external environment for the improvement of professional ethics among accountants.

6.The expression and significance of Smad2 in cervical cancer tissue
Chinese Journal of Primary Medicine and Pharmacy 2012;19(7):972-973
ObjectiveTo explore the expression of Smad2 in cervical carcinoma and analyze the clinical significance of Smad2.MethodsThe expression of Smad2 in normal uterus group( NE group,n =61 ) and cervical carcinoma group( CC group,n =53 ) were detected by immunohistochemistry to analyze the significance of Smad2 in the cervical carcinoma.ResultsPositive rate of expression of Smad2 protein in NE group was 39.3%,positive rate was 77.4% in CC group,statistical difference was found between the two groups(P < 0.01 ).The degree of differentiation of cervical cancer was lower,and the Smad2 positive rate was higher,well-differentiated and poorly differentiated were 52.6% and 91.2%,respectively,and the difference was statistically significante ( P < 0.01 ) ; The invasion of cancer was higher,and the Smad2-positive rate was higher ≤ 1/2 and > 1/2 were 66.7% and 91.3%,respectively,and the difference was statistically significante ( P < 0.05 ).ConclusionThe expression of Smad2 was less; Smad2 was related to depth of invasion and degree of differentiation of cervical carcinoma,which could be used as clinical diagnosis and prognostic markers.
7.The diagnosis and treatment of primary duodenal tumor
International Journal of Surgery 2011;38(8):515-518
Objective To evaluate the preoperative diagnostic procedures and treatment choice of primary tumor of the duodenum (PTD).Method The clinical data of 52 cases with PTD in the last 10 years was analyzed retrospectively.Results The correct diagnostic rate of auxiliary examination was:duodenal endoscopy of 90.5%,air barium double radiography of 80%.Six primary benign tumors of duodenum (PBTD)were resected completely with a 5 year's survival of 100%.Among the 46 cases of primary malignant tumors of duodenum (PMTD),28 cases underwent pancreatoduodenectomy,4 cases received segmental duodenectomy,the remaining 13 cases in which the tumors were unresectable were treated bypass.The resection rate was 69.6% and the 5 years' survival rate was 32.6%.Conclusions Duodenal endoscopy and air barium double radiography are mainstays for the diagnosis of PTD.Segmental duodenectomy and simple tumor resection are curable for PBTD; while for PMTD,the therapy of choice should be pancreatoduodenectomy.

Chinese Journal of Postgraduates of Medicine 2012;35(20):26-29
ObjectiveTo investigate the clinical effect of three-dimensional conformal radiotherapy simultaneously combined with XELOX program(oxaliplatin +capecitabine) for local recurrence of esophageal carcinoma after radiotherapy.MethodsSixty patients with local recurrence of esophageal carcinoma after radiotherapy were divided by random digits table method into treatment group and control group with 30 cases each.The patients in treatment group were treated with three-dimensional conformal radiotherapy simultaneously combined with XELOX program chemotherapy.While control group received three-dimensional conformal radiotherapy.The efficacy between two groups were compared.ResultsThe complete remission rate and efficiency rate in treatment group were significantly higher than those in control group [ 53.3% (16/30) vs.23.3% ( 7/30 ),86.7% ( 26/30 ) vs.63.3% (19/30) ] ( P < 0.05 ).The 1,2,3-year survival rate and median survival time in treatment group were 65.5%,44.8%,34.5% and 24.8 months,which were significantly higher than those in control group (48.3%,41.4%,6.9% and 12.1 months)(P <0.01 ).The incidences of radioactive esophagitis,radioactive pneumonia and thrombocytopenia in treatment group were higher than those in control group,but there were no statistical differences between two groups (P >0.05).The incidences of nausea,vomiting,leukocyte decrease and anemia in treatment group were significantly higher than those in control group [36.7%(11/30) vs.13.3%(4/30),40.0%(12/30) vs.16.7%(5/30),43.3%( 13/30 ) vs.13.3%(4/30),P < 0.05 ].ConclusionsThree-dimensional conformal radiotherapy simultaneously combined with XELOX program can improve short-term efficacy and long-term survival rate of local recurrence of esophageal carcinoma after radiotherapy.

Journal of Jilin University(Medicine Edition) 2001;27(1):96-97
Objective:To improve the prediction of the resectability of esophageal carcinoma by computed tomography.Methods:Eighty-five esoghageal carcinoma cases diagnosed by conventional upper GI tract radiography were enrolled.Three CT signs i.e. angularity,triangular area,and angularity combined with posture were used to observe and to determine the >45。Results:The prediction of resectability by CT were accurate which was confirmed by surgical interventions.Conclusion:Determination of the triangular fat pad between the aorta and the tumor lesion by Ct is reliable and practical in the predication of resectability in the patients with esophageal carcinoma.
10.Progress of histone deacetylase in hepatocellular carcinoma
International Journal of Surgery 2008;35(9):609-612
Histone acetylation and deacetylation is an important regulatory way of gene expression in eukaryotic cells. As a key regulatory enzyme, histone deacetylase is overexpressed in many malignant tumors, including hepa- tocellular carcinoma. In addition, it has been suggested to be a potential therapeutic target for solid tumors. In this study, we review the classification, mechanisms, as well as the expression and regulation of histone deactylases in hepatocelhlar carcinoma.
