Objective To explore the relationship between serum cytokines and liver fibrosis in patients with chronic hepatitis B(CHB), and to discuss their role in the pathogenesis of liver fibrosis. Methods ELISA and RIA techniques were used to detect the levels of transforming growth factor-?1( TGF-?1),tumor necrosis factor-?(TNF-?), Interferon -?(IFN-?), hyaline acid (HA), type III procollagen (PC Ⅲ) and collagen type Ⅳ(C-Ⅳ) in 95 patients with CHB, and contrast study were performed between those serum markers and hepatic pathology. Results The levels of serum TGF-?1, TNF-?, HA, PCⅢ and C-Ⅳ in the patients with CHB were significantly higher than those in normal control group (NC), and were correlated with degree of liver damage positively. Serum levels of TGF-?1, TNF-?, HA, PCⅢ and C-Ⅳ were positive proportion to degree of liver fibrosis (P

Objective To review and analyze minimally invasive right thoracotomy and peripheral cannulation as an alternative strategy in redo heart surgery.Methods From June 2012 to December 2016, 23 reoperative heart procedures were performed through a right lateral thoracotomy with about 5 cm in the third or fourth intercostal space,according to the different diagnosis with the corresponding operations.Results We performed 23 redo heart surgeries,there were 10 female and 13 male patients with a mean age of 41.43 years(range,20 to 69 years).4 mitral perivalvular leakage, 1 prosthetic valve dysfunction, 3 mitral insufficiency after mitral valvuloplasty, 1 aortic insufficiency after ventricular septal defect and aortic repair, 1 mitral insufficiency after ventricular and atrial septal defect repair, 3 residual fistula after surgery repair of ventricular septal defect, 1 tricuspid insufficiency after mitral and aortic valve replacement, 1 tricuspid insufficiency after left atrial myxoma removal,1 tricuspid insufficiency after Bentall surgery, 2 tricuspid insufficiency after mitral valve replacement, 1 mitral insufficiency after ventricular septal defect and mitral valvuloplasty, 2 tricuspid insufficiency after the repair of Ebstein abnormality.We respectively carried out repair of valve leakage, mitral valve replacement, aortic valve replacement, mitral valve repair, tricuspid valvuloplasty, postoperative repair of residual shunt of ventricular septal defect, redo repair of Ebstein abnormality.The effect of the whole group operation of operation was satisfactory, no death during operation and severe complications.All patients were under cardiopulmonary bypass,three patients' ascending aortas were bloked, and nine patients were with cardiopulmonary bypass.It indicated tha the operation was possible at operation time,total blood loss and the frequency of blood transfusion.Conclusion The application of closed thoracic cardiopulmonary bypass and minimally invasive right thoracotomy in redo or multiple cardiac surgery,can avoid reoperative sternotomy risk such as hemorrhage, tissue damage and so on.It shortened the operation time, reduced the risk of surgery and blood transfusion rate, can be used in some of the heart surgery patients again and repeatedly.

Objective To investigate the effect of microcireulation blood flow and altering immunity by Chuanxiongqin,ulinastain and thymosin α1 on sepsis patients.Methods 90 patients were randomly divided into 3 groups(n=30),namely ICU group,Chuanxiongqin group,ulinastain and thymosin α1 group.HLA-DR/CD14+and IL-6,TNF-α,Lac,DD were measured.Results (1)DD showed no significant difference at every time point between ICU group and ulinastain+thymosin α1 group(P＞0.05).DD decreased in Chuanxiongqin group,and was significantly different from the others on the third day.(2)Lac unchanged significantly at every time point in ICU group(P＞0.05).Lac in Chuanxiongqin group and ulinastain+thymeain α1 group tended to decrease,and was statistically different from ICU group on the second day.(3)IL-6 and TNF-α tended to increase at every time point in ICU group(P＜0.05).In ulinastain+thymosin α1 group,IL-6 and TNF-α returned to the level before treatment,HLA-DR/(D14+increased significantly,and was higher than Chuanxiongqin group and ICU group statistically.Conclusion Chuanxiongqin could ameliorate circulation;ulinastsin and thymosin α1 could depress IL-6,TNF-α.So ulinastain and thymosin α1 might protect the immunity of sepsis patients.
