Objective To investigate the expression and regulation of ASPP family mRNA in NSCLC cell lines.and study the diagnostic and therapeutic significances of apoptosis stimulating of ps3 expression in NSCLC Patients.Methods Real-time fluorescence quantitative PCR wag established and used to measure the expression Ievels of ASPP mRNA in NSCLC cell lines A549(wild-type p53)and NCI-H157 (mutant-type p53)with p53 different genetic background,and ASPP mRNA was also detected in NSCLC tissue,peripheral blood of 37 NSCLC patients.Western Bloting was used to examine the levels of ASPP1 and ASPP2 proteins of NSCLC cell Iines.Chemosensitivity of the cell lines to CDDP was analyzed by MTT assay,and detect the change of ASPP1 and ASPP2.Compared with the ASPPs mRNA expression between NSCLC patients and healthy controls.and monitoring ASPPs mRNA expression in patients with NSCLC chemotherapy.Results The slope rotes of standard curves were-3.249,-3.358 respectively.and correlation coefficients were more than 0.98.Amplification efficiency of standard curves were 1.156.1.028 respectively.The IC_(50) values of NCI-H157 and A549 cells were 3.70.10.48 μg/ml respectively.Mean ASPP1 ASPP2 mRNA levels were a statistically significant 2.66 folds and 6.98 folds higher in NCI-H157 cell compared to A549 cell The levels of ASPP1 mRNA in tumor tissues and peripheral blood were (4.27±0.57)×10~3,(2.49±0.32)×10~3 in patients with NSCLC respectively,and the levels of ASPP2 mRNA in tumor tissues and peripheral blood were(2.34±0.75)×10~3,(7.00±1.17)×10~3 in Patients with NSCLC respectively.The levels of ASPP1 and ASPP2 mRNA in tissues and peripheral blood were(1.32±0.21)×10~4,(1.46±0.31)×10~4 and(1.38±0.19)×10~4,(1.28±0.18)×10~4 in control groups respectively.The ASPP1,ASPP2 mRNA levels in patients with NSCLC were significantly lower than those of control groups(t=2.58,3.94,3.62,3.76,P＜0.05).Before chemotherapy the levels of ASPP1 and ASPP2 mRNA in patients with NSCLc were(2.34±0.56)×10~3 and(6.64±0.72)×10~3,and after 2 periods of postoperative chemotherapy the levels were(3.66±0.64)×10~3 and(9.42±0.44)×10~3,the expression was higher than those of ehemotherapy before(t=3.02,4.50,P＜0.05).Conclusions The expression of ASPP1.ASPP2 mRNA in p53 mutant-type cell lines is higher than that in p53 wild-type cell lines.The expression of ASPP maybe has close relationship with chemotherapeutic sensitivity of NSCLC.In NSCLC patient chemotherapy process,the change of ASPP1 and ASPP2 mRNA expression may be related with chemotherapy medicine function.Enhance the expression of ASPP1 and ASPP2 will be beneficial to the tumot treatment.

Objective　To study the effects of measures for preventing early postburn damage in improving survival rate of burn patients during the third stage. Methods　12 568 burn cases admitted to our institute were chronically divided into three groups (1958-1980;1981-1990;1991-2000). Total burn surface area (TBSA), survival rate, incidence of burn shock, systemic infection and organ damage as well as the main treatments adopted in the recent decade were retrospectively analyzed. Results　Incidence of burn shock, systemic infection and organ damage were significantly lower, and the total survival rate and the survival rate in patients with different TBSA were markedly higher in the third group as compared with those in the first and the second group. Incidence of organ damage in patients treated with delayed fast fluid infusion, early escharectomy en masse, early enteral feeding, early prevention of inhalation injury and gut bacterial translocation were also significantly lower than in the control. Conclusion Measures taken in the third group for preventing early postburn damage play an important role in improving the survival rate of burn patients.

Objective To evaluate the diagnostic value of endoscopic ultrasonography (EUS) for unexplained bile duct expansion in patients before retrograde cholangiopancreatography (ERCP). Methods Sixty patients with unknown causes of bile duct dilatation were included in this study. Patients were examined by abdominal ultrasound (TUS), CT and (or) magnetic resonance imaging (MRCP) suggesting the dilatation of common bile duct, suspecting biliary pancreatic disease with unknown cause. EUS diagnosis was performed before ERCP surgery. The final diagnosis was confirmed by ERCP, pathology and follow-up diagnosis. Results Thirty-nine patients were diagnosed as distal bile duct stone by ERCP, 38 were diagnosed by EUS, and one case was diagnosed as common bile duct bottom tumors by EUS. There were 10 cases were diagnosed as common bile duct bottom tumors by ERCP and surgical pathology, 2 cases were diagnosed as biliary papillomatosis, 2 cases were diagnosed as periampullary carcinoma. There were 11, 0 and 3 cases were diagnosed by EUS. One case was diagnosed as distal bile duct stone, which was diagnosed as common bile duct bottom tumor by EUS. Two cases were diagnosed as papillary tumor of the bile duct, one of which was diagnosed as inflammatory stenosis, another one was diagnosed as periampullary carcinoma by EUS. Results of postoperative follow-up confirmed that 7 cases were duodenal papilla inflammatory stenosis. Eight cases were diagnosed by EUS, one of them was followed up and pathologically diagnosed as biliary papillomatosis by ERCP. The diagnostic accuray was 95%(57/60). Conclusion EUS has higher value in the diagnosis of unexplained bile duct expansion, which especially can improve the diagnostic rate of distal bile duct stone compared with that of MRCP detection, and can guide selectively ERCP, improve the therapeutic effect, and reduce its risk .

The zinc finger antiviral protein (ZAP) specifically inhibits the replication of Moloney murine leukemia virus (MLV) and Sindbis virus (SIN), but has very modest inhibitory effect on HIV. Previous studies suggest that ZAP directly binds to the viral RNA and recruit the RNA degradation machinery to degrade the target RNA. The HIV-1 Tat and Rev are regulatory proteins which bind to HIV RNA. Tat and Rev were fused with ZAP in various manners. Two fusion proteins, ZAP-Tat and ZAP-Rev were found to be able to inhibit the expression HIV-1 vector.

Objective To assess the relationship between serum vitamin D and autoimmune thyroid disease.Methods Subjects included total 520 persons receiving regular health examination,and serum calcium,phosphorus,parathyroid hormone (PTH),thyroid peroxidase autoantibody (TPOAb) and 25-dihydroxy vitamin Ds was measured.The incidence of 25-dihydroxy vitamin D3 deficiency (≤30 μ g/L)was observed.The relationship between 25-dihydroxy vitamin D3 deficiency and autoimmune thyroid disease was analyzed.Results The serum 25-dihydroxy vitamin D3 of all the subjects was (24.47 ± 7.21) μ g/L,and the incidence of 25-dihydroxy vitamin D3 deficiency (≤30 μg/L) was 61.15％ (318/520),and the positive rate of TPOAb was 21.54％ (112/520).The proportion of TPOAb ＞ 50 kU/L or ＞ 100 kU/L in subjects with 25-dihydroxy vitamin D3≤30 μ g/L was higher than that in subjects with 25-dihydroxy vitamin D3 ＞ 30 μg/L [25.79％(82/318) vs.19.80％(40/202) and 9.43％(30/318) vs.4.46％(9/202)],and there was significant difference (P ＜ 0.05).The relationship between 25-dihydroxy vitamin D3 and TPOAb was assessed and showed significant inverse correlation (r =-0.13,P ＜0.05).Conclusions Vitamin D deficiency is very common in the population,and autoimmune thyroid disease is related with vitamin D deficiency,which may has impact on the body's immune regulation.Specific mechanism and whether vitamin D supplementation can intervene and treat autoimmune thyroid disease need further study.

Objective To observe the effect of oxidized low-density lipoproteins (Ox-LDL),15-Deoxy-△ 12,14-prostaglandin J2 ( 15d-PGJ2 ),leukotrienes B4 ( LTB4 ) on mRNA expressions of peroxisome proliferator activated receptor γ2 ( PPARγ2 ),receptor activator of NF-κB ligand (RANKL),alkaline phosphatase ( ALP),and osteoprotegerin(OPG) in osteoblastic cells of rats; and to investigate the influence of these PPARγ2 endogenous ligands on bone metabolism.Methods Rat osteoblastic cells were cultured in vitro for 24 h in medium with different PPARγ2 endogenous ligands at various concentrations ( the final concentrations of Ox-LDL were 0,12.5,25,50μg/ml; the final concentrations of 15 d-PGJ2 were 0,10,20,30 μmol/L; the final concentrations of LTB4 were 0,0.1,1.0,10 μ mol/L).RT-PCR was performed to determine the mRNA expressions of PPARγ2,RANKL,ALP,and OPG in osteoblastic cells.Results RT-PCR analysis showed that Ox-LDL,15d-PGJ2,and LTB4 all down-regulated the mRNA expressions of RANKL,ALP,and OPG,while up-regulated the mRNA expressions of PPARγ2 in osteoblastic cells in a dose-dependent manner.Significant differences were found in interclass comparisons( P＜0.05 or P＜ 0.01 ).Conclusions These findings suggest that Ox-LDL,15d-PGJ2,and LTB4 suppress the expressions of osteogenic genes through activating the transcription activity of PPARγ2,and this may be a plausible mechanism of senile osteoporosis.
