Methods Murine DNFB allergic contact dermatitis was used as an animal model, and was treated with 4 traditional Chinese medicinal compounds which were composed of Chinese materia medica with activities to suppress type Ⅳ allergic reaction. Results The results showed that the effect of compound Ⅲ composed of Paeoniae obovata Maxim(赤芍), Fructus Gardeniae(栀子), Herba Schizonepetae(荆芥), Herba Spirodelae(浮萍) and Poria(茯苓), possessing multiple potencies of cooling and promoting blood, clearing heat, expelling wind and eliminating dampness, was strongest among the compounds tested, and the compound up regulated the serum level of calcitonin gene related peptide which was lowered in the mice with DNFB induced dermatitis. Conclusion It is suggested that the compounds with suppressive effect on type Ⅳ allergic reaction might improve the therapeutic effect in clinical practice.

Objective To summarize the experience of perioperative management of lung volume reduction surgery(LVRS) under video-assisted thoracoscopy.Methods A total of 40 patients with severe chronic obstructive pulmonary disease(COPD) underwent LVRS under video-assisted thoracoscopy.A mini-incision thoracotomy was given in 23 of them.During the operation,the Endo-GIA was utilized to resect 20%~30% of total volume of affected lung.Results The LVRS was performed in bilateral lungs in 13 patients(under thoracoscopy only in 7 patients and with the assistance of mini-incision thoracotomy in 6 patients) and in unilateral lung in 27 patients(under thoracoscopy only in 10 patients and with the assistance of mini-incision thoracotomy in 17 patients).There were no surgery-related deaths.All the patients were discharged from the hospital 9~41 days(mean,18 days) after operation.Not only symptoms of dyspnea were obviously relieved but also the respiratory index was upgraded by 1~2 grades.The comparisons on pulmonary functions between preoperative time and 1 month after operation indicated a great improvement postoperatively,including the forced expiratory volume in 1 second(FEV_1)(48.3%?4.9% vs 68.5%?5.6% predicted;t=17.169,P=0.000),the residual volume(RV)(270.0%?23.6% vs 188.0%?19.8% predicted;t=16.835,P=0.000),and the total lung capacity(TLC)((123.0%?9.8%) vs 102.0%?8.7% predicted;t=10.135,P=0.000).Postoperative complications included air leakage in 10 patients,lung infection in 5 patients,and bronchial asthma in 3 patients,all of whom were cured after symptomatic management.A follow-up was conducted in 37 patients for 3~77 months(mean,46 months).Three patients died of lung cancer at 6,10, and 20 postoperative months,respectively.Two patients died of esophageal cancer at 3 and 8 postoperative months,respectively.And one patient died of cerebrovascular disease at 6 postoperative months.The remaining 31 patients survived. Conclusions Proper perioperative management is of great importance for a successful surgery and a rapid postoperative recovery.

Objective To investigate clinical effects of video assisted thoracoscopic lung volume reduction surgery(LVRS) for severe emphysema. Methods Six patients with severe emphysema underwent lung volume reduction surgery by video assisted thoracoscopy.The LVRS was performed unilateraly in 4 and bilateraly in 2 through median stemination.20%～30% of total volume of lung was resected. Results There was no operative death.All patients were followed up for 3 to 17 months.After LVRS,the mean forced expiratory volume in 1 second(FEV 1) and PaO 2 increased by 24 6% and 8 3%,respectively,Total lung capacity(TLC),residual volume(RV) and ventilatory assistance decreased by 24 6%,20 3% and 47 1% respectively Conclusions LVRS by video-assited thoracoscopy is an effective and safe technique for patients with severe emphysema.It can relieve dyspnea and improve excise tolerance and the quality of life.

Objective To study the X-ray and CT features of costal eosinophilic granuloma for a better understanding.Methods Eight patients with costal eosinophilic granuloma proved by surgery or biopsy were analyzed retrospectively.All patients had X-ray plain film, 6 patients had CT examination,including a case of enhanced CT scan.Results All 8 lesions were solitary.Six lesions were in the anterior rib and 2 in the posterior rib.On X-ray, all case showed single cavity and oval lesion with clear boundary.On CT images, 5 lesions demonstrated expansile destruction of bone with cortical bone thinning, and 3 were osteolystic destruction with soft tissue mass around.On the patient with enhanced CT scan, the lesions showed a moderate and uniform enhancement.Conclusion The X-ray and CT findings of costal eosinophilic granuloma are characteristic.

Purpose:To study the expression and clinical significance of p27 in esophageal carcinoma. Methods:Immunohistochemical staining was used to determine the expression of p27 in 32 cases of normal esophageal issues and 88 cases of esophageal carcinoma.Results:The positive incidences of P27 expression in esophageal carcinoma was 40.9% while in normal esophageal issues it was 75.0%. The expression of p27 was correlated to degree of differentiation of carcinoma and lymph node metastasis, but not to length, depth of invasion and TNM stage. The p27 negative group was seen to have the worst survival rate among all groups.Conclusions:The results suggest that p27 gene plays an important role in carcinogenesis and progress of esophageal carcinoma. Expression of P27 may prove to be valuable in prognosis assessment of esophageal carcinoma.

Objective To explore the mechanism of siRNA targeted hTERT gene to inhibit bladder cancer T24 cell growth by decreasing c-myc and TGF-?1 expression. Methods shRNA-hTERT-pTZU6+1 vectors were constructed by RNAi-DNA vector technique, then the vectors were transfected into bladder cancer T24 cells,and the most effective vector and its optimal concentration were screened using RT-PCR to detect hTERT expression in T24 cells.The T24 cell growth, the alternative of cell phase,the expression of hTERT,c-myc and TGF-?1 were detected by flow cytometry,RT-PCR and immunohistochemistry. Results Three shRNA-hTERT-pTZU6+1 vectors were successfully constructed.The most effective vector was ph2-shRNA vector,and its optimal concentration was 1.0 ?g.This vector decreased the cell growth and the cell number of S phase from 65.2% to 38.6%,increased the cell number of G0/G1 phase from 32.0% to 57.9%,and attenuated both mRNA and protein expressions of hTERT,c-myc and TGF-?1 in T24 cells. Conclusions Targeted hTERT gene with siRNA may inhibit the cell proliferation of bladder cancer;down-regulating hTERT expression by attenuating the expression of c-myc and TGF-?1 is probably involved in the mechanism.

AIM: To investigate the transcription regulation of the promoter of human telomerase reverse transcriptase (hTERT) by transcription factors c-myc and [STBX]mad1. METHODS: The various plasmids including wild type hTERT (Tw) or mutant type hTERT (Td) which both harboring luciferase gene, the expression plasmids of c-myc and [STBX]mad1, and their control vectors were constructed. The plasmids were co-trans fected into bladder cancer cell lines T24, EJ and control cells COS-7 or fibrocytes by DOTAP liposome in various combining manner, respectively. The reporter gene luciferase activities in various groups were measured 48 h after transfection. RESULTS: The luciferase activities in T24 and EJ cells treated with Tw were much higher than that in COS-7 and fibrocytes cells treated with Tw, as well as higher than that in T24 and EJ cells treated with Td, respectively. In bladder cancer T24 and EJ cells, transcription factor c-myc and [STBX]mad1 positively and negatively regulated Tw expression in a dose-dependent manner. However, the effects of c-myc and [STBX]mad1 on Td were completely opposite to Tw. Combined with c-myc and [STBX]mad1, down-regulation of Tw expression was observed. CONCLUSION: c-myc and [STBX]mad1 regulates the transcriptional activity of hTERT promoter in bladder cancer cells, and the effects might highly depend on the conservative E-box sequence CACGTG.

Objective To investigate the relationship between procoagulation of HFGL 2 and abnormality of coagulation in patients with systemic lupus erythematosus (SLE) by detecting the expression of HFGL2/fibroleukin in peripheral blood mononuclear cell(PBMC) of SLE patients. Methods A polyclonal antibody against HFGL2 was applied to detecting the expression of HFGL2 protein in 32 SLE patients and 15 healthy volunteers by immunohistochemistry. Semi-quantitative measurement of HFGL2 expression in the blood specimen was done with high multiple image analytical system(HMIAS). Results The expression of HFGL2 in PBMC from 23 active SLE patients was significantly higher than that in the controls, which showed a positive correlation with the disease activity. Conclusion The expression of HFGL2 in PBMC is probably correlated with the pathogenesis and disease activity of SLE.
