To construct the Bac-to-Bac expression system of Bombyx mori nucleopolyhedrovirus (BmNPV), a transfer vector was constructed which contained an Escherichia coli (E. coli) mini-F replicon and a lacZ: attTN7: lacZ cassette within the upstream and downstream regions of the BmNPV polyhedrin gene. B. mori larvae were cotransfected with wild-type BmNPV genomic DNA and the transfer vector through subcutaneous injection to generate recombinant viruses by homologous recombination in vivo. The genomic DNA of budded viruses extracted from the hemolymph of the transfected larvae was used to transform E. coli DH10B. Recombinant bacmids were screened by kanamycin resistance, PCR and restriction enzyme (REN) digestion. One of the bacmid colonies, BmBacJS13, which had similar REN profiles to that of wild-type BmNPV, was selected for further research. To investigate the infectivity of BmBacJS13, the polyhedrin gene was introduced into the bacmid and the resultant recombinant (BmBacJS13-ph) was transfected to BmN cells. The budded viruses were collected from the supernatant of the transfected cells and used for infecting BmN cells. Growth curve analysis indicated that BmBacJS13-ph had a similar growth curve to that of wild-type BmNPV. Bio-assays indicated that BmBacJS13-ph was also infectious to B. mori larvae.

Objective To evaluate the efficacy and side effects of adjuvant chemotherapy plus in-tensity modulated radiotherapy (IMRT) after breast-conserving surgery for stage Ⅰ and Ⅱ breast cancer.Methods After breast-conserving surgery, 108 patients received six cycles of chemotherapy followed by IM-RT. The irradiation dose of the whole breast was 50 Gy given by 25 fractions, followed by 10 Gy boost to the tumor bed given by 5 fractions with electron beams. Patients with positive estrone receptor or progesterone re-ceptor were given endocrine treatment, mostly with tamoxifen. Results The follow-up rate was 100% by December 2007. The number of patients followed-up at 1-, 2- and 3-year was 108,88 and 58. The 1-, 2- and 3-year over survival rates were 100% ,100% and 98%. Three patients had local recurrence. Different degree of dermatitis occurred with good long-term cosmetic results. No severe side effects occurred such as radiation-induced pneumonitis, pulmonary fibrosis and heart injury. Conclusions Breast cancer patients treated by adjuvant chemotherapy plus IMRT after breast-conserving surgery have high survival rate and low side-effect rate. The survival quality and local control can be improved.

Objective This study was undertaken to examine possible relationship between attempted suicide and underachievement,bullying,low life satisfaction and low self-concept at school.Methods An anonymous self-report survey assessing demographic characteristics and the major risk factors of teenage attempted suicide was completed by students from 16 middle schools in grades seven to twelve in 4 counties of Anhui province (age 10 to 21 years).An anonymous questionnaire was used to rate attempted suicide,bullying involvement and learning performance.Attempted suicide was defined as: experiencing specific suicide actions at least one time during the 12 months preceding the survey.Multidimensional Students' Life Satisfaction Scale and Children' s Self-concept Scale were used to evaluate satisfaction and self-conscience on and at respectively.In total,10 894 respondents substantially completed the survey.Multiple logistic-regression analyses,controlling for socio-demographic variables,was used to analyze if underachievement,bullying,low school life satisfaction and low children' s self-conscience at school had been risk factors.Results 629 participants (5.8%) reported having made at least one attempted suicide within the last 12 months.Students being underachieved were significantly having more attempted suicide events than those excellent students (X2=11.39,P=0.023).Students being both bully-victims and practiced bully were significantly more than those being only practiced bully (28.7% vs.15.8%,P＜0.001),being victims (28.7% vs.10.6%,P＜0.001) or having neither of them (28.7% vs.4.8%,P＜0.001).Results from multiple logistic regression analyses showed that underachievement,bullying,lower school life satisfaction and low self-conscience were risk factors for attempted suicide.Conclusion Data from this study confirmed that school bullying and children' s self-conscience at school were significantly associated with attempted suicide among rural middle school students in Anhui province.It is of importance to improve the school' s environments to reduce the risk of attempted suicide among this group.

OBJECTIVETo observe the clinical efficacy on sleep disorder in the intervention of flying needling therapy and compare the efficacy difference among flying needling therapy, estazolam and non-acupoint acupuncture.

METHODSThree hundred and fifteen cases of sleep disorder were randomized into a flying needling group (110 cases), an estazolam group (107 cases) and a non-acupoint acupuncture group (98 cases). In the flying needling group, the flying needling therapy was applied to Sanyinjiao (SP 6), Anmian (EX HN22), Shenmen (HT 7) and so on. Additionally, vitamin B1 was prescribed for oral administration and the intradermal needle method was given at the Back-shu points. In the estazolam group, estazolam was prescribed for oral administration. Also the non-acupoint acupuncture and the acupoint sticking therapy on the Back-shu points were given additionally. In the non-acupoint acupuncture group, the non-acupoint acupuncture, oral administration of vitamin B1 and the acupoint sticking therapy on the Back-shu points were applied. The treatment of 2 weeks were required in all the groups. The efficacy and the score of PSQI (Pittsburgh sleep quality index) were observed in the 2-week follow-up visit.

RESULTSThe total effective rate in the flying needling group was 84.1% (90/107), which was superior to 59.7% (62/104) in the estazolam group and 25.0% (24/96) in the non-acupoint acupuncture group (both P < 0.05). In the follow-up observation, the score of each item and the total score of PSQI were lower apparently than those before treatment in each group (all P < 0.05), and those in the flying needling group were lower apparently than those in the other two groups (all P < 0.05).

CONCLUSIONThe flying needling therapy as the chief therapeutic method effectively improves the sleep quality for the patients with sleep disorder, which is apparently superior to estazolam and non-acupoint acupuncture.

Objective To investigate the prevalence and influencing factors related to abuse and negligence against the elderly in the rural areas. Methods 975 elderly over 60 years from 41counties in Anhui province were included. All participants completed an anonymous questionnaire including items as: educational background, marital condition, income, child-discipline, rude action to parents, daily activities, physical functions, having chronic illness, abuse and negligence against the elderly, etc. Results In the last year, rates of common physical abuse, serious physical abuse,emotional abuse, financial exploitation, negligence, overall abuse and negligence against the elderly were 4.5%, 1.5%, 26.9%, 4.9%, 7.2%, 29.9% respectively. Among the 281 victims, 80.4% reported that they were suffered more than 3 times of abuse and neglect episodes, and 34.9% reported that they were suffered more than 2 forms of abuse and negligence. The primary sadism was carried out by the daughter-in-law or son-in-law (43.2%) of the elderly. Low activity on daily life and having chronic illness were the risk factors causing common physical abuse while better education was the protective factor to it, Low ability in managing daily activity of living was the risk factor causing serions physical abuse. Less active on daily life and having rude action to parents were the risk factors to emotional abuse, but being strict with their children was the protective factor to emotional abuse. Less active on daily life, often beating their children and having rude action to parents were the risk factors related to financial exploitation. Less active on daily life, having rude action to parents and having bad physical functions were the risk factors causing negligence. Less active on daily life and having rude manner to parents were the risk factors of overall elderly abuse and negligence, but being strict with their children was protective factor to the abuse and negligence against the elderly. Conclusion High prevalence on abuse and negligence against the elderly was seen in the rural areas of China. Different forms on elderly abuse and negligence were affected by different factors that called for more attention to be paid to those elderly with lower ability in managing their daily life.

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.

OBJECTIVETo assess the diagnostic values of immunohistochemistry and SYT-SSX fusion gene detection for synovial sarcoma.

METHODSBased on clinical features, histological and immunohistochemical profiles, 195 cases of tumors were divided into three diagnostic categories: definitive synovial sarcoma, probable synovial sarcoma and possible synovial sarcoma. RT-PCR Detection of the SYT-SSX fusion gene was performed using paraffin embedded tissue samples. Comparison between RT-PCR and immunohistochemistry results was carried out and their diagnostic value was evaluated.

RESULTSThere were 62 (31.8%) definite synovial sarcomas, 49 (25.1%) probable synovial sarcomas and 84 cases (43.1%) possible synovial sarcomas. SYT-SSX fusion gene was detected in 140 (78.2%) cases overall, including 94.7% (54/57) definite synovial sarcomas, 86.0% (37/43) probable synovial sarcomas and 62.0% (49/79) possible synovial sarcomas. In tumors in the certain and probable synovial sarcoma categories, the positive rates of epithelial membrane antigen (EMA) were significantly higher in the SYT-SSX positive cases than SYT-SSX-negative cases (P = 0.022, P = 0.010, respectively). EMA was positively correlated with the presence of SYT-SSX (r(s) = 0.431, P = 0.001, r(s) = 0.463, P = 0.002, respectively). However, such a correlation was not seen in cytokeratin (CK), vimentin or S-100 protein immunostains (P > 0.05). In tumors of possible synovial sarcoma category, there were no significant differences of CK, EMA, vimentin or S-100 protein between SYT-SSX-positive and SYT-SSX-negative tumors.

CONCLUSIONSSYT-SSX fusion gene detection is not needed when the conventional approaches are diagnostic. EMA positivity has a similar diagnostic value to that of SYT-SSX by RT-PCR for tumors in the probable synovial sarcoma category. However, detection of SYT-SSX is very important for diagnosis of the tumors in the category of possible synovial sarcoma.
