Silent information regulator 1 (SIRT1) is a kind of histone deacetylase which dependents on nicotinamide adenine dinucleotide.It is involved in the occurrence and development of tumors.Data show that SIRT1 is highly expressed in many tumors,such as gastric cancer,breast cancer,prostate cancer and so on.On the other hand,the expression of SIRT1 is lower in many other types of tumors,including glioblastomas,bladder cancer,ovarian cancer and so on.Therefore,the role of SIRT1 in tumor formation process is still uncertain and controversial.

Objective To investigate the expression and clinical significance of zinc finger gene 217 (ZNF217) in human papillary thyroid carcinoma.Methods The expressions of ZNF217 mRNA and protein were detected by quantitative realtime PCR and Western blot in papillary thyroid carcinoma tissues (n =20) and adjacent normal tissues (n =20),and the data were analyzed.Results The expressions of ZNF217 mRNA and protein in papillary thyroid carcinoma were significantly higher than those in adjacent normal tissues (96.72 ± 44.19 vs 4.86 ±3.55,0.994 ± 0.172 vs 0.195 ± 0.061,both P＜0.01),being higher in the papillary thyroid carcinoma with capsule invasion compared with that without capsule invasion (P＜0.01).The expressions of ZNF217 mRNA and protein in papillary thyroid carcinoma were not related to gender,age,tumor size,TNM stage or lymph node metastasis (all P＞0.05).Conclusions The overexpression of ZNF217 may be associated with the oncogenesis and progress of papillary thyroid carcinoma and capsule invasion,and thus is expected to become a new target for prevention and treatment of papillary thyroid carcinoma.

Objective To study the expression of ZNF217 and EF1α gene in the pathological scars and to investigate role and probable mechanism in the pathogenesis of abnormal scar.Methods Quantitative real-time PCR and Western blot were performed to detect the expression and distribution of mRNA and protein of ZNF217 and EF1α in hypertrophic scar (10 cases),keloid (10 cases),normal scar (10 cases),and normal skin (10 cases),and statistics was used to analyze the data.Results The expression of ZNF217 mRNA and protein in the normal skin,normal scar,hypertrophic scar and keloid were 1.46±0.397,1.45±0.265,4.49±0.999,5.47±0.808; 0.276±0.0211,0.299±0.0150,0.743t0.0509 and 0.747±0.0377,respectively.The expression of EF1α mRNA and prorein in the normal skin,normal scar,hypertrophic scar,and keloid were 1.47±0.469,1.47±0.218,5.10±1.68,5.74±1.92; 0.505±0.0371,0.518±0.0153,0.780±0.0369 and 0.792±0.0290,respectively.The positive rate of mRNA and protein of ZNF217 and EF1α was not statistically different between the hypertrophic scar and keloid (P＞0.05),while they were all remarkably significant in comparison between normal scar and abnormal scar (P＜0.01).In pathological scar mRNA and protein of ZNF217 and EF1α showed a strong positive correlation.Conclusions The expression of ZNF217 and EF1α is increased in pathological scar.Therefore,ZNF217 and EF1α overexpression may play an important role in the proliferation of fibroblasts and in the pathogenesis of pathological scar.

Alemtuzumab (Campath) was successfully injected in 21 kidney transplant patients,7 islet transplant patients and 1 simultaneous kidney and islet transplant patient for either prevention or treatment of graft rejection.Prophylactic administration was successfully completed in all patients without discontinuation.Adverse events were not observed in 11 patients (38%),but hypertension in 18 patients (62%),shivering in 3 patients (10.3%),high fever in 3 patients (10.3%),and bronchospasm in 1 patient (3%),respectively.All complications alleviated after proper therapy.During the prophylactic administration of alemtuzumab,strict,timely and proper ward-management was needed.Care for lung,perineum,skin,diet and psychological nursing were necessary.Neither graft acute rejection nor graft chronic rejection episode occurred in all patients during 6 months to 2 years follow-up.Therefore,long term effects of Alamtuzumab and consequences of lymphocytopenia need further observation.

Objective:To study the antitumor mechanism of W40,a monomer purified from Wedelia prostrate (Hook.et Arn.) Hemsl.Methods:The effects of W40 on the cell proliferative of GLC-82 cells were detected by MTT assay and colony formation assay.The migratory abilities of GLC-82 cells were observed by wound healing assay.Cell apoptosis was evaluated by Annexin V-FITC/PI staining analysis.The levels of apoptosis-relative proteins and cell proliferation-related proteins,such as Caspase-3,PARP,Stat3 and ERK,were detected by Western blotting.Results:MTF assay showed that W40 had a significant cytotoxic effect on non-small cell lung cancer GLC-82 cells.Colony formation assays showed that W40 significantly inhibited GLC-82 cells proliferation.The migration of GLC-82 cells was inhibited by W40 in a dose-dependent manner.Flow cytometry showed that the apoptotic rate increased gradually in a concentration-dependent manner.W40 down-regulated Stat3 as decreasing p-Stat3 and downstream proteins of Bcl-2 and Mcl-1.At the same time,W40 up-regulated the expression of pro-apoptotic protein Bax,and increased the cleavaged Caspase-9,Caspase-3 and PARP.W40 also down-regulated BRAF / MAPK / ERK signal pathway as decreasing p-BRAF,p-MEK and p-ERK.Conclusions:W40 induced apoptosis by inhibiting BRAF / MAPK / ERK and Stat3 signaling pathways.

Objective To explore promoter methylation of HIC1 gene and the expression of HIC1/SIRT1 related to the occurrence, development, and metastasis of papillary thyroid carcinoma. Methods Using Bisulfite sequencing PCR to analyze the promoter methylation of HIC1 gene. Using quantitative real-time PCR and Western blot to analyze expression differences of HIC1 and SIRT1 genes in tissues of papillary thyroid carcinoma(40 cases) and in adjacent normal thyroid(40 cases), of which datas were analyzed by statistics. Results The degree of HIC1 gene promoter methylation was significantly higher than that in adjacent normal tissues(P<0. 01). The degree of HIC1 gene promoter methylation in papillary thyroid carcinoma was related to lymph node metastasis, age, and the tumor-node-metastasis stages(P<0. 01). Compared with the expression of HIC1 mRNA and protein in adjacent normal thyroid tissue, that in papillary thyroid carcinoma was significantly lower(P<0. 01), while the expression of SIRT1 mRNA and protein in papillary thyroid carcinoma was significantly higher(P<0. 01). The lower expression of HIC1 mRNA and protein in the tumor tissues was related to the stage of lymph node metastasis, age, and the tumor-node-metastasis stages(P<0. 05). There was a strong negative correlation between the degree of HIC1 gene promoter methylation and expression of HIC1 in papillary thyroid carcinoma(P<0. 05). The expression of HIC1 mRNA and protein between that of SIRT1 also showed a strong negative correlation(P<0. 01). Conclusion Promoter hypermethylation of HIC1 and aberrant expression of HIC1/SIRT1 in papillary thyroid carcinoma may play a significant role in the oncogenesis and progress of papillary thyroid carcinoma. HIC1 is expected to become a new marker for prevention and treatment of papillary thyroid carcinoma.

Objective To analyze and study the connections between hypovolemia and lower extremity deep venous thrombosis (LDVT)in patients with cerebral infarction. Methods A total of 504 hospitalized patients with cerebral in-farction were selected.

Results Analysis on the results of ROC curves showed ROC area under the curve of urea nitrogen/creatinine ratio in the diag-nosis of LDVT in 10-14 days after admission was 0.788(95%CI 0.727-0.848),the optimal diagnostic cut-off point was 101.705, the sensitivity was 58%, and the specificity was 88.7%; ROC area under the curve of plasma osmotic pres-sure was 0.892 (95%CI 0.836-0.949), the optimal diagnostic cut-off point was 305.77 mmol/L, the sensitivity was 85.5%, and the specificity was 90.8%; ROC area under the curve of the combined index was 0.895 (95%CI 0.837-0.952); ROC area under the curve of D-dimer was 0.883(95%CI0.832-0.935), the optimal diagnostic cut-off point was 3.055 ug/L,the sensitivity was 85.5%, and the specificity was 82.1%. Conclusion Combined index of urea nitro-gen/creatinine ratio and plasma osmotic pressure in the diagnosis of LVDT is better than D-dimer, which is beneficial for early diagnosis.
