The zinc finger protein A20 exists in many kinds of ceils in the body and plays multiple roles in physiological and pathological processes such as regulation of immune response,inflammatory diseases and cancers by inhibiting cell apoptosis induced by tumor necrosis factor (TNF) and restricting NFKB signaling pathway.Recently,the role of A20 in generation and development of tumors draws wide attention,hence,we summarized recent research progress of the relation between A20 and cancer in this review.

Objective To compare the effects of a single injection of palonosetron and tropise-tron to prevent postoperative nausea and vomiting (PONV ) in gynecological surgeries. Methods Sixty patients undergoing elective major gynecological surgeries with general anesthesia (Apfel score ≥ 3 ) were included and randomized to group P (palonosetron ) and group T (tropisetron),30 patients in each group.All patients received general anesthesia with tracheal intuba-tion,and palonosetron 0.25 mg or tropisetron 5 mg were injected before anesthesia respectively in two groups.Intravenous hydromorphine was delivered for postoperative analgesia in all patients. PONV were evaluated and followed up for 72 hours.The degree of PONV was recorded and the com-plete response rate (CR)and complete control rate (CC)were calculated.Results The degree of PONV in 0-24 h and 24-48 h was milder in group P than in group T (P <0.05),while in 48-72 h the degree of PONV was similar between the two groups.In group P,5 patients had vomiting postopera-tively with the failure period of treatment of (1 9.6±9.4)h,and no patients needed rescue treatments. While in group T,1 9 patients suffered from vomiting with the failure period of treatment of (20.6± 4.5)h,and rescue treatments were delivered 3 times in total.The CR and CC of preventing PONV in 0-24 h,24-48 h and 0-72 h were significantly higher in group P than in group T (P <0.05).The CR and CC of the two groups were comparable in 48-72 h postoperatively.Conclusion A preoperative single dose of palonosetron 0.25 mg is better than tropisetron 5 mg in preventing PONV within 48hours after gynecological surgery.

Objective To facilitate standing and walking after rehabilitation training by designing and using individualized ischial weight bearing orthosis for patients with various conditions of the lower limbs. Methods An orthosis with ischial support was ordered and tailored according to the condition of the patient's affected lower limb. Adaptive standing and walking training were administered daily. The functional recovery after the assembly of the orthosis was observed. Results The patients' standing and walking ability improved significantly after the training with the ischial weight bearing orthosis. The standing time was significantly longer than without the orthosis, and the walking distance was notably increased. Conclusion An ischial weight bearing orthosis has a significant effect on the recovery of standing and walking capability.

Objective To evaluate the prognosis in patients with hepatocarcinoma by examining the expression of α-fetoprotein (AFP) and des γ prothrombin (DCP).Methods Retrospectively analyzed the expression of AFP and DCP in 105 patients received curative hepatectomy.Divided the patients into three groups as follow:the tumor markers were both negative pre-and post-operation (Group N) ; the tumor markers decreased to normal after operation (Group D) ; the tumor markers kept positive or decreased but still higher positive after operation (Group P).Then combined the two markers and divided the patients into 4 groups:two markers both negative(AFP + DCP +)(Group A) ; AFP + DCP-(Group B) ; AFP-DCP + (Group C) ; AFP-DCP-(Group D).Results High AFP and DCP levels were significantly associated with poor tumor-free and overall survival.The presence of large size and advanced stage were significantly associated with Group P.Overall survival in the AFP-N group was significantly better than that of other groups and overall survival in DCP-N group were significantly better than that of the P group.After the combination,Group A had the best overall and tumor free survival rate while the D group had the worst.The differences between B and C group were not significant.Conclusions AFP and DCP can be both used solely as tumor markers and the expressions of them are associated with the prognosis.The combination of two markers can be used for better prediction of hepatocarcinoma.

Objective To compare of intervention embolization and operation in the treatment of brain aneurysms.Methods 60 cerebral aneurysm patients using random number table method were divided into two groups each 30 cases,group A given intervention embolization;group B given surgical operation treatment.They were followed for 3months,the bleed Glasgow results score,matrix metalloproteinases 2(MMP-2) level change and the length of time were recorded.Results After treatment,A group total effective rate was 73.4％,postoperative treatment to bleed again rate was 10.0％ (3/30),B group was 76.7％,6.7％ (2/30),two groups had no statistically significant differences (x2 =0.09,0.22,all P ＞ 0.05 ) before treatment M MP-2 level between ;The two groups was statistically significant ( t =1.21,P ＞ 0.05 ) ;Two groups after surgical treatment 3 d MMP-2 levels were ( 20.1 ± 8.7 ) μg/L,( 35.7 ±8.9 ) μg/L respectively,which was statistically significant ( t =3.33,P ＜ 0.05 ).A group of hospitalization time (8.6 ±1.5 ) d,group B ( 13.2 ± 1.3 ) d,the difference between two groups was statistically significant ( t =3.18,P ＜ 0.05 ).Conclusion For brain aneurysm patients,the intervention embolization had no obvious difference in curative effect with operation,but could reduce the time in hospital and significantly reduced MMP-2 level.

Objective To investigate the expression of peripheral blood (PB) CD4+ CD25+ Foxp3+ regulatory T cells (Tregs) in patients with benign end-stage liver disease after liver transplantation and the relationship between levels of PB Tregs and acute rejection. Methods A prospective analysis was performed on 55 consecutive patients who underwent liver transplantation.Fourteen out of 55 cases suffered from acute rejection after liver transplantation were defined as rejection group,while the rest patients were classified into no acute rejection group. PB was obtained from liver transplant patients at different time points longitudinally: pre-transplant, post-transplant within one year and acute rejection. The circulating CD4+ CD25+ Foxp3+ Tregs in PB were measured by flow cytometry. Blood samples were drawn during acute rejection, at the same time, liver biopsies were performed. The circulating CD4+ CD25+ Foxp3+ Tregs were compared between two groups.Results There was no difference between two groups in levels of circulating CD4+ CD25+ Foxp3 + Tregs cells pre-transplant. However, the levels of circulating CD4+ CD25+ Foxp3+ Tregs in rejection group were decreased significantly as compared with no-rejection group (2. 23 % ± 0. 54 % vs. 2. 99 % ±0. 86 %,P＜0.01). The frequency of CD4+ CD25+ Foxp3+ T cells was negatively correlated with rejection activity index (RAI) (r = - 0. 80, P＜0. 01 ). Conclusion Monitoring PB CD4+ CD25+ Foxp3+ Tregs levels may be helpful in evaluating the immune state and act as a more sensitive marker for acute rejection diagnosis in the patients following liver transplantation.
