Cervical cancer is the second most common malignant tumor of women all over the world.Infection with oncogenic human papilloma virus ( HPV) types is the most important risk factor to cause cervical cancer.The viral genome of HPV consists of three regions:the early region (E), the late region (L) and the long control region (LCR).The early proteins (E1, E2, E4, E5, E6, E7 ) play vital roles in the continuous virus expression and replication in cells.Among these proteins, E6 protein has the closest relationship with the tumorogenesis and development of cervical cancer.Many mechanisms of the HPV encoded early protein E6 in in-ducing cervical cancer have been characterized, including degradation of p53 protein, activation of telomerase, interaction with PDZ protein, disturbance of cellular signaling pathways, inhibition of immune recognition and blockage of cellular apoptosis.HPV E6 pro-tein may be a preferred target in prevention and treatment of cervical cancer.

Objective To analyze and compare the advantages and disadvantages in high-field MRI scan and LAVA enhanced in the display of hepatic carcinoma capsule,in order to improve the early diagnosis and differential diagnosis level of primary hepatic carcinoma by MRI.Methods MRI data of 233 patients of primary hepatic carcinoma were retrospective analysed by two radiologists. Results 233 cases of primary hepatic carcinoma,except for 18 cases of diffuse hepatocellular carcinoma,a total of 239 lesions (54 small hepatocellular carcinoma,76 nodular hepatocellular carcinoma,109 massive hepatocellular carcinoma )were found .Hepato-cellular carcinoma capsule display rate was 139/239(58.16%).119 T1 WI,87 cases were found in T2 WI,and 139 cases were found in LAVA enhanced scan.25 lisions showed complete capsule on T1 WI,12 lisions showed complete capsule on T2 WI,59 lisions showed complete capsule on LAVA enhanced scan.Small hepatocellular carcinoma displayed capsule 21/54 (38.9%),nodular hepa-tocellular carcinoma 53/76 (69.7%),massive hepatocellular carcinoma 65/109 (59.6%).Conclusion High-field MRI conventional scan and LAVA enhenced scan can display PHC capsule better,LAVA enhanced (portal phase + delay phase)showed PHC capsule better than T1 WI and T2 WI.

OBJECTIVETo compare the applicative effect of four diagnostic criteria of metabolic syndrome (MS) among the urban adult population of Zhejiang Province.

METHODSAccording to multi-stage stratified and proportional to size, cluster, random sampling principle, 3 417 adults population at urban areas were extracted by random number method from 320 families of Shangcheng and Jianggan community in Hangzhou,Jiangdong community in Ningbo and Wucheng community in Jinhua in 2009 and 2010 respectively, which excluded pregnant, wet nurse, children, and those who were at least 18 years of age. Height, weight, waist, blood pressure, fasting plasma glucose (FBG) , 2-hour postprandial blood glucose (2h-PBG), TG and HDL-C of all the subjects were measured by standard method. MS was diagnosed and compared according to four diagnostic criteria:Chinese Medical Association Diabetic Society (CDS), Joint Committee for Developing Chinese Guidelines (JCDCG), American National Cholesterol Education Program Adult Treatment PaneI II in 2005 (ATPIII) and International Diabetes Federation (IDF), respectively.

RESULTSThe high prevalence of MS diagnosed by the criteria of ATPIII was 21.6% (737/3 417) , while the lowest prevalence diagnosed by CDS was 9.8% (335/3 417), the result of consistency check demonstrated the MS diagnostic criteria of ATPIII and IDF, ATPIII and JCDCG were in strong and the same accordance with the concordance rate, Kappa value was 0.75, while the consistency of the criteria of ATP III and CDS were in relatively weak agreement, Kappa value was 0.53; the detection result of MS abnormal components showed the highest proportion of having ≥ 3 risk factors was presented by ATPIII among subjects diagnosed as MS (100.0%) , meanwhile, the lowest proportion of having ≥ 3 risk factors was also found by ATPIII among those MS-free (0.8%) .

CONCLUSIONSThe criteria of ATPIII may have more sensitivity when screening MS and its abnormal components.However, it's limited to extrapolate the results from the cross-sectional survey to the total population.

Objective To investigate the effects of nutritional treatment in patients with AIDS.Methods A total of 104 HIV/AIDS patients with a total score of nutritional risk screening≥3 were divided into two groups:observation group (n =50) who were treated with nutritional therapy,control group(n =54) who refused nutritional treatment.The changes of parameters in two groups were observed before(I0) and 1 month after (I1)treatment and 3 months after treatment (I2).Results Compare with thecontrol group,the weight,BMI and ALB in observation group were higher at the time of I1 and I2 (P＜0.05);Except for Hb and ALB,the other indexes had significant difference between the time of I0,I1,I2 in control group.While all the indexes had significant differencebetween the time of I0,I1,I2 in observation group.Conclusion Long-term comprehensive nutritional therapy can improve the nutritional status of AIDS patients,which provides patients with a good basis for anti-viral treatment.
