Researches find that microRNAs(miRNAs) participate in cell proliferation,differentiation and apoptosis.Dysregulation of miRNA exist in almost all kinds of tumors,including esophageal cancer.MiRNAs bind to mRNA of oncogene or tumor suppressor gene by perfectly or partly base-pair complementarity,and then,promote mRNA degradation or inhibit translation of target mRNA.Recently studies have comfirmed that miRNA functions as a significant regulator in esophageal cancer and it is involved in tumorigenesis,development and prognosis.MiR-21 binds to programmed cell death 4(PDCD4) mRNA and inhibits the translation of PDCD4,then promotes tumorigenesis of esophageal cancer.MiR-106-25 polycistron is activated by genomic amplification,and then suppresses the expressions of P21 and Rim,and subsequently promotes the occurrence and progress of esophageal cancer.

[Objective]To observe the activity of anti-inflammatory and analgesia of Danweisan.[Methods]The analgesia action of Danweisan was determined with twisting method,and the anti-inflammatory effect of Danweisan was evaluated with xylene induced ear tumefaction.The effects of the small,medium,large dosages of Danweisan group(2,3,4g/kg) on twisting and ear tumefaction in mouse were assessed.[Results] Compared with the normal group,it was shown to exert dramatic inhibitory effect with concentration-dependence on mouse twisting and ear tumefaction in the Danweisan group.[Conclusion]Danwesan has a remarkable analgesia activity and a better anti-inflammatory action than asprine.

Objective:To investigate the regulatory mechanism of LBP on T lymphocytes excessive apoptosis and the mRNA expression of apoptotic genes in aged rats Methods:T lymphocyte apoptosis and the expression of pre apoptotic and anti apoptotic genes (Fas, FasL, TNFR1, Bax, Bcl2 and TNFR2) from young rats and old rats treated with or without LBP were studied using flow cytometry and fluorescence real time quantitative RT PCR Results:LBP could effectively downregulate the percentage of T cell apoptosis in aged rats At the same time LBP also downregulated the transcription level of TNFR1 gene and upregulated the transcription level of Bcl 2 in T cells from old rats Conclusion:The T cell excessive apoptosis in old rats could be effectively downregulated with LBP, by the by of decreasing the expression of pro apoptotic gene and enhancing the expression of anti apoptotic gene

Objective:To evaluate the efficacy of Epstein-Barr nuclear antigen 1/immunoglobulin A (EBNA1/IgA), BamH1 Z transactivator/IgA (Zta/IgA), capsid antigen/IgA (VCA/IgA), and Epstein-Barr virus deoxyribonucleic acid (EBV-DNA) in detecting different stages of na-sopharyngeal carcinoma (NPC). The relationship between the EBV markers and stages of NPC was also analyzed. Methods:Blood sam-ples of 152 untreated patients with NPC and 675 healthy subjects were collected.ELISA was used to detect the serum levels of EBNA1/IgA, Zta/IgA, and VCA/IgA. Fluorescence quantitative PCR (FQ-PCR) was used to detect the plasma levels of EBV-DNA. ROC and correla-tion analyses were employed to assess the detection assays for NPC diagnosis. The positive rates of EBV markers in NPC patients in dif-ferent stages were analyzed statistically. Results: The positive rates of EBNA1/IgA, Zta/IgA, VCA/IgA, and EBV-DNA in NPC patients were higher than those in the healthy individuals. The expression of EBNA1/IgA was relatively high in early NPC. The sensitivity of EB-NA1/IgA was 77.8%. In advanced NPC, the level of EBV-DNA was high, and the sensitivity of EBV-DNA was 88.8%. The specificity of EBV-DNA and EBNA1/IgA could reach more than 96%. The combination of EBV-DNA and EBNA1/IgA showed the best diagnostic value, with a sensitivity of 92.1%(early stage 82.5%, advanced stage 98.9%) and a specificity of 96.9%. The positive rates of EBV-DNA were positively associated with the NPC clinic stage and N stage. The positives rates of Zta/IgA were positively associated with the NPC N stage. Conclusion:The best single index for NPC screening in an asymptomatic population is EBNA1/IgA. EBV–DNA is an ideal index for auxiliary diagnostics of advanced NPC. The combination of EBV-DNA and EBNA1/IgA shows the best diagnostic value. EBV-DNA is an important index in the stage and illness monitoring of NPC. Zta/IgA can indirectly reflect the character of lymph node metastasis, and it may be useful in assessment of NPC surveillance.

Objective To analyze the incidence of remaining symptoms after discectomy with different operation,and investigate its causes and clinical significance.Methods Two hundred and twentyfour patients were followed up.The incidence of remaining symptoms and clinicai situation after discectomy were observed with different operation:discectomy (110 patients,single group),discectomy with bone grafting internal fixation (70 patients,fusion group),and discectomy with dynamic fixation (44 patients,non-fusion group).The SPSS 19.0 software was used to analyze the data.Results One hundred and sixpatients (47.32％,106/224) occurred remaining symptoms in 224 patients.In single group was 69 patients (62.73％,69/110),in fusion group was 26 patients (37.14％,26/70),and in non-fusion group was 11 patients (25.00％,11/44).The incidence of remaining symptoms among three groups was significant difference(x2 =22.177,P =0.000).The incidence of remaining symptoms in single group was significantly higher than that in non-fusion group and fusion group (x2 =17.921,P =0.000;x2 =11.235,P =0.001).The incidence of remaining symptoms in non-fusion group and fusion group had no significant difference (x2 =1.817,P =0.178).Conclusions There is significantly different in the incidence of lumbar disc herniation with different surgery methods.Discectomy with bone grafting internal fixation and with dynamic fixation can effectively reduce the incidence of remaining symptoms.

Objective To investigate the epidemic characteristics and trends of incidence and mortality of prostate cancer in cancer registration areas in Zhejiang province from 2000 to 2009.Methods Clinical data incidence and mortality of prostate cancer were collected from 6 cancer registration areas in Zhejiang province,including Hangzhou,Jiaxing,Jiashan,Haining,Shangyu and Xianju.Crude rates,standardized rate and change trend,age-specific rates and annual percent change (APC,95％ CI) of prostate cancer were checked,sorted and analyzed in Zhejiang Cancer Center.Results The prostate cancer incidence rate from 2000 to 2009 was 9.79/100 000,age-standardized incidence rates by world standard population (ASIRW) was 6.39/100 000,and the incidence cumulative risk of males aged 0-74 was 0.72％ ; while the mortality rate was 2.73/100 000,age-standardized mortality rates by world standard population was 1.74/100 000,and the mortality cumulative risk of males aged 0-74 was 0.14％.Age-specific incidence of prostate cancer remained low before 50,years old and peaked at over 85-year-old group (130.30/100 000).Age-specific mortality of prostate cancer increased after 55,and also peaked at over 85-year-old group (81.19/100 000).The annual prostate cancer incidence rate generally grew from 1.39/100 000 (2000) to 13.89/100 000 (2009),and the APC was 14.18％ (95％ CI,9.68％-18.98％).Meanwhile,the prostate cancer mortality rate also increased from 1.52/100 000 (2000) to 3.58/100 000 (2009),and the APC was 11.83％ (95％ CI,5.69％-18.33％).Conclusion Prostate cancer incidence and mortality in Zhejiang cancer registration areas increased sharply,and the prevention and treatment of prostate cancer should be strengthened.

Objective To evaluate the role of temporary arteriovenous fistula(AVF) in the treatment of acute deep venous thrombosis(DVT) with Amplatz thrombectomy device(ATD). Method Seventy-six cases of acute DVT underwent mechanical thrombolysis with ATD, in which 50 cases received a temporary AVF after interventional therapy. Result One case died of pulmonary embolism. Ipsilateral limbs swelling subsided and pain alleviated in the remaining 72 cases since first post-operative day. Secondary contralateral DVT developed in 2 cases on the 7th post-operative day. The patency of temporary AVF was 86%(43/50). Sixty-eight cases (90.7%) were followed-up for 10~42 months post-operatively with limbs swelling completely subsided in 59 cases and ameliorated in 6 cases. Secondary inferior vena cava thrombosis developed in one case and 2 cases died of unrelated diseases. Conclusion Temporary AVF increases blood flow volume and blood velocity in the thrombectomized vein segment to improve the vein patency, hence is a valuable auxiliary means of ATD.
