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.

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.

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.

"Resolving,espulsing and tonifying" three methods are the general outline of endotherapy in surgery of TCM.The author of this article thinks that pelvic inflammation and appendagitis can be classified in internal ulcer and vusceral carbuncle,and it can be treated by "Resolving,espulsing and tonifying" three methods.As the general programme of treating female inflammatory aphoria in different periods,the three methods can avoid exfetatio and promote the probability of pregnancy.Resolving method is applied in acute period of inflammatory aphoria,active period of chronic inflammatory and chronic pelvic inflammation when abdominal mass has formed but vital qi is not deficient.The pathologic character in this period is sufficiency of vital qi and excessive of pathogenic qi.Expulsing method is applied in inflammatory aphoria patients whose pathogenic has not been cleared but the vital qi has been harmed,at this time damp heat pathogen poison remain in uterus meridians and the nvital qi has no power to resist pathogen,and whose corporeity is always week and infects pathogen poison which results in the course of diseases being repeated and prolonged.Tonifying method is applied after the resolving and espulsing methods have been used.In this period,damp heat stasis have been cleared,inflammation and inflammatory matters have been absorbed,disease has been improved and patient has had condition to be pregnant.Tonifying method can promote human generative function and improve the possibility of conception.
