Objective To explore the role of HPV16 and p53 protein in the pathogenesis of tumors of nasal cavity and sinus of Chinese people. Methods The expression of HPV16 and p53 in 58 tumor samples of nasal cavity and sinus was detected by immunohistochemistry. Results There was no p53 expression in inverted pipillomas(IP). HPV16 infection rate in IP was 62.5%. The positive rate of p53 protein in the malignant tumors and IP with atypical hyperplasia was 56.0% and 44.4%, respectively, and HPV16 infection rate in the both tissues was 24.0% and 66.7%, respectively. The positive rate of p53 and HPV16 simultaneous expression in IP with atypical hyperplasia were 33.3%, which was higher than that in the malignant tumors and IP without atypical hyperplasia. Conclusion The high-risk HPV16 infection may be primary cause of IP. p53 gene mutation may be close relation with the pathogenesis of nasal cavity and sinus malignant tumors. HPV16 and p53 may have synergic effect in the malignant transformation of nasal cavity and sinus benign tumors.

Objective To observe the clinical efficacy of acupoint application with Xiong Bi Tie in treating unstable angina pectoris. Method Sixty eligible subjects with unstable angina pectoris were randomized into a control group (treated with basic Western medication) and a treatment group (intervened by the basic Western medication plus acupoint application with Xiong Bi Tie), 30 cases in each group. The symptoms of unstable angina pectoris, syndromes and signs of traditional Chinese medicine (TCM), and cardiogram were recorded, and the clinical efficacies were also observed. Result In comparing the improvement of angina pectoris, the treatment group was better than the control group, with a statistical significance (P<0.05). From the perspective of TCM syndromes and signs, the efficacy of the treatment group was significantly better than that of the control group (P<0.05). Regarding the cardiogram, the total effective rate was 76.7% in the treatment group versus 50.0% in the control group, and the difference was statistically significant (P<0.05). Conclusion Acupoint application with Xiong Bi Tie can significantly improve the angina symptoms and cardiogram result of unstable angina pectoris (blood stagnation caused by qi deficiency syndrome), and it’s safe and easy-to-operate.

Objective:To realize the different disaster recovery of infectious disease net reporting system of Chinese Center for Disease Control and Prevention (China CDC) in the same city.Methods:We adopted B/S/DBMS three-tier architecture to deploy the infectious disease net reporting system in the disaster recovery center, realized data level disaster recovery through the remote replication technology, realized application level disaster recovery through technology of the data asynchronous replicating and transmitted disaster recovery data of the infectious disease net reporting system through asynchronous mode. Results: According to the existing resources, we established different disaster recovery center of the same city, realized the disaster recovery data backup of important information system in the same city, completed the security of software and hardware in information security level protection, and passed the level evaluation of Ministry of Public Security.Conclusion: The establishment of disaster recovery center in the off-sete of same city can make sure the security of the system and data, and ensure the continuity of work efficiency.

0.05). Conclusion The p53 gene mutation has close relation with nasal malignant tumor , and may has no related to the pathogenesis of IP possible.

There is a high prevalence of gastric cancer in China,but most of the patients are diagnosed at advanced stages,when chemotherapy is regarded as an important component of the multimodal treatment.Chemotherapy has demonstrated advantages over best suppor-tive care in prolonging survival and improving quality of life.Over the past 40 years,the clinical responses of two or three-drug combination chemotherapy regimens have been accepted,and 5-fluorouracil,cisplatin and epirubicin have been most frequently used in gastric cancer.Recently,the therapeutic effects of advanced gastric cancer treated by new regimen consisted of docetaxel,irinotecan,oxaliplatin and capecitabine have been further enhanced.The molecular targeted agent,cetuximab and bevacizumab,combined with chemotherapy,would be more promising therapeutic regimens in the treatment of advanced gastric caner.

ObjectiveTo evaluate the therapeutic effect of encircling constriction of superficial femoral vein in the treatment of primary deep venous insuficiency(PDVI).MethodsFrom Jan.2004 to Jun.2011,187 patients( 196 lower extremities)with primary deep venous insufficiency were treated with encircling constriction of venous wall at the first pair of superficial femoral venous valve pulse superficial varicose stripping.Results The 183 limbs in 176 patients were followed-up from 7 months to 8 years,with a mean period for 63.5 months.Ninety-four point one percent of the patients were followed up (176/187).Clinical symptomatic improvement achieved in 87.4％ ( 160/183 ) of the lower extremities.There was 2.2％ ( 4/183 ) of recurrence of the varicose vein,9.3％ ( 17/183 ) of light edema,8％ ( 2/25 ) of recurrence of ulcer.ConclusionEncircling constriction of superficial femoral vein is an effective method in the treatment of primary deep venous valve insufficiency.

OBJECTIVE To discuss the gentamycin-induced ototoxity and mechanism on cochlear outer hair cells. METHODS All the guinea pigs were randomly divided into 3 groups. Gentamycin, gentimycin plus furosemide and normal saline were intraperitoneally injected for 6 days respectively. The amplititude of distortion product otoacoustic emissions (DPOAE)urface prepration of cochlear basilar membrane, hair cells’ apoptosis and expression of caspase-3 after injection were analyzed. RESULTS Reduction of the DPOAE amplitude, hair cell damage, apoptosis and Caspase-3 expression were observed in group injected with gentamycin as well as in group injected with gentamycin plus furosemide. CONCLUSION Gentamycin should induce hair cell damage in the cochlea of guinea pigs and Caspase-3 plays an important role in the process of hair cell apoptosis.
