The role of autophagy is known to be highly complex and context-dependent, and may be characterized as both tumor suppression and tumor promotion in some tumors, such as breast cancer and prostate cancer. This review outlines recent advances in the studies of the involvement of autophagy in the development, progression and treatment of prostate cancer, focusing on autophagy modulation during androgen deprivation, with a special discussion on the regulatory effect of androgens on the autophagy of prostate cancer cells. A critical evaluation and analysis of the studies suggests that autophagy inhibition combined with androgen deprivation therapy is a promising approach to the treatment of prostate cancer.

Objective: To learn the health literacy level and its influencing factors among junior high school students in Jiaxing, so as to provide basis for health promotion of adolescents. Methods: The junior high school students who had been studying and living in Jiaxing for more than six months were selected by multistage cluster random sampling method. A questionnaire survey was conducted to collect general information and health literacy level (including basic knowledge and concept, healthy lifestyle and behaviors, and basic skills) of these selected students. The multivariate logistic regression model was used to analyze the influencing factors for health literacy. Results : Of 1 773 questionnaires collected, 1 738 were valid, accounting for 98.03%. The level of health literacy in the junior high school students in Jiaxing was 22.84% ( 95%CI: 20.87%-24.82% ), The levels of basic knowledge and concept, healthy lifestyle and behaviors, and basic skills were 55.29% ( 95%CI: 52.95%-57.63% ), 21.75% ( 95%CI: 19.81%-23.69% ), 53.05% ( 95%CI: 50.70%-55.40%), respectively. Multivariate logistic regression analysis showed that the second grade and above ( OR: 1.609-1.835, 95%CI: 1.195-2.459 ), mother's educational level of technical secondary school/senior high school and above ( OR: 1.965-1.976, 95%CI: 1.276-3.357 ), and self-rated academic achievement of medium and above ( OR: 1.881-2.441, 95%CI: 1.359-3.335 ) were the promoting factors for health literacy level of junior high school students; self rated health status as unhealthy ( OR=0.254, 95%CI: 0.089-0.721 ) was an obstructive factor. Conclusions The health literacy level of the junior high school students in Jiaxing was 22.84%. The level of healthy lifestyle and behaviors was the lowest in three aspects. Grade, mother's educational level, self-rated academic performance and self-rated health status may have impacts on health literacy level of junior high school students.

Objective To evaluate the quality of the portal images acquired by computed radiography(CR)system and conventional screen-film system,respectively.Methods imaging plates (IP)and X-ray films of a home-devised lead phantom with a leakage of 6.45% were acquired,and modulation transfer function(MTF)curves of the both images were measured using edge method.Portal images of 40 nasopharyngeal cancer patients were acquired by IP and screen-film system respectively.Two doctors with similar experience evaluated the damage degree of petrosa] bone,the receiver operating characteristic(ROC)curve of CR images and general images were drawn according to two doctors evaluation results.Results The identification frequency of CR system and screen-film system were 1.159 and 0.806 Lp/mm respectively.For doctor one,the area under ROC curve of CR images and general images were 0.802 and 0.742 respectively.For doctor two,the area under ROC curve of CR images and general images were 0.751 and 0.600 respectively.The MTF curve and ROC curve of CR are both better than those of screen-film system.Conclusion The image quality of CR portal imaging is much better than that of screen-film system.The utility of CR in linear accelerator for portal imaging is promising in clinic.

OBJECTIVETo introduce a better surgical approach for the resection of tumors involving the anterior and middle skull base and the fronto-orbito-ethmoidal area.

METHODSA "T" form incision was made in the fronto-orbito-ethmoidal region and along the nasal pyramid down. Parts of ethmoid sinus, lamina papyracea, fronto-orbito bone and behind wall of frontal sinus were resected in order to expose the tumors in the anterior skull base and the fronto-orbito-ethmoidal region. Then, the tumor was resected partly under the operation microscope, protecting the neighbouring important structures, for instance: optic nerve, internal carotid artery, sella, meninx, etc. The nasal pyramid was repaired and fixed to the frontal bone with titanium board and titanium nail in order to resume the appearance of a good face.

RESULTSThirteen patients received tumour resection through this approach. The patients were followed-up for 24 months, 11 patients showed no tumour recurrence, no severe complication, such as cerebrospinal rhinorrhea, meningoencephlocele, etc, in this series. The facial appearance was good.

CONCLUSIONSThe approach via the fronto-orbito-ethmoidal region is a good surgical procedure to resect the tumors involving the anterior and middle skull base and the fronto-orbito-ethmoidal area.

OBJECTIVETo explore indication and approaches of neurotomy of tibial nerve for the treatment of the talipes equinovarus and spastic paralysis.

METHODA total of 25 patients including 15 patients with cerebral paralysis and other 10 patients were diagnosed with clear etiology, spastic muscles with supplied nerves were analyzed in detail, neurotomy of the tibial nerve was performed under microscope, during operation, motor nerve was lovated with electronic stimuli and monitored with induced electromyography. The surgical results were analyzed.

RESULTSA total of 36 of 37 (97%) neurotomy of the tibial nerve were improved with dorsum flex of ankle at 10 - 45 degree, and 22 of 24 (85%) talipes equinovarus improved clinically. Of 37 feet with surgery, 24 feet (65%) were in normal position and could touch ground completely, 9 feet (24%) had 10 degree with ground or could contact ground with external one third of the feet, 4 feet (11%) were abnormal. Of 25 patents, 21 (84%) had improvement of motor activity at discretion, 5 patients (20%) improved dramatically. All the 4 patients failed after the operation were cerebral paralysis, and were presumably related to disorders of spinal function, abnormal reflex and the disappearance of inhibitory reflex.

CONCLUSIONNeurotomy is an effective method to treat talipes equinovarus, and can improve the motor activity of low extremity.

OBJECTIVETo make an inquiry into method of typing of hemorrhagic fever with renal syndrome (HFRS).

METHODAverage monthly rates were calculated on the basis of data from 1995 to 1999, then cluster analysis was carried out to type out endemic areas.

RESULTSCompared with the results of 36 surveillance spots from 1980 to 1992, twenty-four surveillance spots had the same results (66.7%). Twenty-three surveillance spots had the same results with the original data in 1999 (82.1%).

CONCLUSIONHFRS incidences increased in spring or in summer, but decreased in autumn or in winter. Cluster analysis seemed to be a supplementary method in distinguishing the epidemic types for HFRS.

OBJECTIVETo review the epidemiologic and clinical characteristics of 96 cases with novel H1N1 influenza A, and improve the diagnosis and treatment level of novel H1N1 influenza A.

METHODS96 cases of novel H1N1 influenza A admitted to the isolation wards from Oct 20 to Sep 23, 2009 were studied. Their epidemiologic, clinical, laboratory, and radiologic characteristics were analyzed.

RESULTSThe median age of the 96 patients was 26.52 +/- 10.62 years (range, 5 to 60 years). Sixty-four of the 96 patients had a close contact with novel H1N1 influenza A patients. The main symptoms included fever 100%, cough 86.4% , sore throat 66.6% and myalgia 32.3%.

CONCLUSIONThe clinical presentation of novel H1N1 infection is largely indistinguishable from that of seasonal influenza. Combines both a symptom complex with the epidemiological investigation and laboratory characteristics can improve the accuracy of diagnosis of novel H1N1 influenza A.
