Objective To explore urban middle students' learning strategies, as well as to provide substantial evidences for learning strategies counselling in middle schools. Methods The differences between sexes,among grades and between class types were examined by t test and MANOVA for 466 middle school students. Resukts The participants'total learning strategies level (3.17±0.52) was slightly higher than midpoint "3" of moderate level. Significant score differences of total learning strategies was found between genders((3.11 ±0.54)vs(3.22±0.48), t=2.30, P＜0.05) and among grades ((3.26±0.51)vs(3.09±0.51), t=3.50, P＜0.01). Interaction of grade and class type on learning strategies was significant (F=7.997,P＜0.01). Conclusion Learning strategies level of middle school students exist genders and grades,and grade and cla.ss type have interaction obviously.

ObjectiveTo explore relations between self-control and aggressive behavior in college students.Methods 310 students were surveyed with Buss-Perry aggression questionnaire and self-control questionnaire(SCQ).Results①High score group in SCQ was higher with physical aggression,verbal aggression,anger,hostility and aggression scores ( respectively ( 25.86 ± 5.04 ),( 15.27 ± 2.76 ),( 20.12 ± 4.26 ),( 23.87 ±4.45 ),( 85.11 ± 11.75 ) ) than the low group ( respectively (20.26 ± 5.04 ),( 14.04 ± 3.35 ),( 13.76 ± 4.68 ),( 19.37 ±5.31 ),(67.43 ± 13.56) ),the difference was statistically significant (P＜ 0.01 ).②Self-control scores had significant positive correlations with aggressive behavior scores( r=0.60,P＜ 0.01 ).③Self-control dimension (self-emotional,simplistic tendency,impulsive risk-taking) were significant predictors of aggressive behavior(P ＜0.01 ).ConclusionSelf-control is closely related with aggressive behavior,and it is a significant predictor of aggressive behavior.

Objective:To construct an eukaryotic radiation-inducible expressing vector of the human perforin N-terminal(hPFN-N),and to investigate the distribution and the killing effect of human perforin N-terminal truncated 118 amino acid polypeptide (rhPFN-N,22-139aa) on tumor cells.Methods:The gene hPFN-N was amplified by PCR from the plasmid pcDNA3.1(+)/hPFN and an enkaryotic radiation-inducible expression vector pcDNA3.1(+)/ Egr-hPFN-N was constructed after DNA recombination.After transfecting SPC-A1 cells with this recombination vector via liposome mediation,the expression of the hPFN-N protein was detected by RT-PCR and Immunocytochemical method and the killing effect of hPFN-N protein was assessed by standard MTT chromatometry.Results:DNA sequencing and restriction endonuclease digestion analysis indicated that the eukaryotic radiation-inducible expressing vector pcDNA3.1(+)/ Egr-hPFN-N had been constructed successfully.After the recombinant plasmid being transfected into SPC-A1 cells and being irradiated by X ray,RT-PCR verified the expression of hPFN-N mRNA.The result of Immunocytochemical assay was positive and in MTT assay the killing activity of rhPFN-N on target cells was 29.2%.Conclusion:After being irradiated the hPFN-N gene is expressed on the cell membrane and the killing activity of rhPFN-N on target cells is 29.2%.

Objective To observe the changes of mechanical pain thresholds and autophagy related proteins microtubule-associated protein 1 light chain 3 (LC3) and sequestosome 1 (SQSTM1 also known as p62) expression levels in the C57BL/6 mouse models of chronic prostatitis/ chronic pelvic pain syndrome (CP/CPPS),and provide animal experimental evidence for CP/CPPS pain and autophagy study.Methods 36 male C57BL/6 mice were randomly divided into three groups: the model group,control group and na(i)ve group.The CP/CPPS model was established by subcutaneous injection in the lower abdomen region with suspension liquid,containing protein extract of male SD rat prostate gland and complete Freund adjuvant.At 1month and 6 months after modeling,the mice were sacrificed and prostate tissues were harvested for histological examination using HE staining.Mechanical tactile hyperalgesia was measured with von Frey filaments.The autophagy-related proteins LC3 and p62 expression levels were detected by immunohistochemistry,respectively.The average IOD was measured by Image Pro Plus 6.0,and the statistical analysis was performed with GraphPad Prism 5 software.Results The histopathology showed the appearance of chronic prostatitis in the model group,representing hyperplasia and lymphocytic infiltration to a different degree and lasted for 6 months after modeling.Moreover,prostate intraepithelial neoplasia (PIN) appeared in the model group at 6 months after modeling,characterized by the disappearence of basement membrane and obvious nuclear abnormality,while the control and na(i)ve groups showed normal histology during the 1-6 months.Compared with the control and na(i)ve groups,the mechanical pain threshold in the model group was significantly decreased along with the time from (0.353±0.154) g at 0 week to (0.008±0.00) g at 22 weeks (P<0.05).The average IOD of LC3 and p62 expression in the model group was significantly increased with timing from [(2.767±0.464)%,(2.872±1.642)%] at 1month to [(13.501±1.900)%,(9.07±0.49)%] at 6 month,P<0.05.Conclusions A CP/CPPS model is successfully established in C57BL/6 mice.For the model group,the mechanical pain threshold is decreased and autophagy levels are increased gradually with time.These phenomena show that chronic inflammation microenvironment may promote pain and autophagy activity in the prostate,which is closely related with the occurrence and development of prostatic intraepithelial neoplasia.

Objective:To investigate the effect of body mass index(BMI), waist circumference(WC) and waist hip ratio (WHR) on blood pressure, serum lipids, renal function, protein and lymphocyte. Methods:175 middle and elderly patients were measured. Results:Compared to normal weight cases, SBP and uric-acid were significantly higher in over-weight cases. Triglyceride, SBP and DBP were all significantly higher in obesity cases. When waist circumference was beyond 85 cm in women, triglyceride, lymphocyte and DBP were all significantly higher than those in normal weight women. When waist circumference was beyond 90 cm in men, triglyceride was significantly higher than that in normal weight men. Conclusion:When BMI increases, triglyceride and blood pressure will increase accordingly. When WC is higher than normal, triglyceride in male and female will be higher. Control of obesity, is helpful to prevent cardiovascular diseases.

Objective To investigate the impact of fatty liver on antiviral effect in the patients with chronic hepatitis B (CHB) .Methods A total of 204 patients with hepatitis Be antigen (HBeAg ) positive CHB in the outpatient department of our hospital from January 2011 to April 2014 were selected as the research subjects and divided into the two groups according to wheth‐er complicating fatty liver :the simple CHB group(control group ,122 cases) and CHB complicating nonalcoholic fatty liver disease (NAFID) group(observation group ,82 cases) .The two groups all received the 24‐week antiviral therapy of adefovir (10 mg/d) . The differences in the normalization rate of ALT/AST (biochemical response) ,HBeAg negative conversion rate (serological re‐sponse) and HBV DNA negative conversion rate(virological response) were compared between the two groups .Then the cases ob‐taining the virological response after treatment in the two groups were compared again .Among the cases obtaining virological re‐sponse,thedifferencesinthenormalizationrateofALT/AST(biochemicalresponse)andHBeAgnegativeconversionrate(serologi‐cal response) were compared between the simple CHB group and CHB complicating NAFID group .Results The normalization rate of ALT/AST after 24‐week treatment in the CHB complicating NAFID group was 58 .5% ,which was significantly lower than 72 .1% in the simple CHB group ,the difference was statistically significant ;the negative conversion rate of HBV DNA and HBeAg after 24‐week treatment in the simple CHB group was 67 .2% and 52 .5% ,which were significantly higher than 51 .2% and 37 .8%respectively ,the differences were statistically significant ;among the cases obtaining the virological response ,the normalization rate of ALT/AST in the simple CHB group was 96 .3% ,which was significantly higher than 66 .7% in the CHB complicating NAFID group ,the difference was statistically significant .But among the cases obtaining the virological response ,the negative conversion rate of HBeAg was 78 .0% in the simple CHB group and 73 .8% in the CHB complicating NAFID group ,the simple CHB group was slightly higher than the CHB complicating NAFID group without statistical difference .Conclusion NAFLD has impact on the antiviral effect of adefovir treatment in CHB patients with positive HBeAg ,whereas complicating NAFLD is an important reason for reaching the virological response and serological response ,but without reaching the biochemical response in the antiviral treatment of CHB complicating NAFID .

OBJECTIVE: To evaluate the efficacy and safety of Yiqing Shuangjie Capsule and Tablet in treating acute upper respiratory tract infection with wind-warm syndrome. METHODS: The multiple center, double-blinded, double-dummy and randomized controlled method was conducted. Three hundred and sixty patients were randomly divided into the treatment group A (n=120, treated with Yiqing Shuangjie Capsule and Chaihuang analogues), treatment group B (n=120, treated with Yiqing Shuangjie Tablet and Chaihuang analogues) and the control group (n=120, treated with Chaihuang Tablet and Yiqing Shuangjie Capsule analogues). Every drug was administered 3 pills each time. Patients in the three groups were all treated for 5 days and three times daily. The accumulated scores of syndrome, clinical symptoms, adverse effect and body temperature were recorded before and after the treatment. The safety indexes, such as routine tests of blood, urine and stool, hepatic and renal function tests and electrocardiogram (ECG) were taken before and after the treatment. RESULTS: Three cases were excluded and eighteen cases lost to follow-up. There were 343 patients who entered to the intention-to-treat (ITT) analysis and 339 patients fitted in the per-protocol population set (PPS) analysis. After treatment, the therapeutic effects of respiratory tract infection were calculated by ITT and PPS analysis respectively. The rates of total obvious effect were 84.96% and 87.27% respectively in the treatment group A, and the total response rates were 96.46% and 97.27% respectively. The rates of total obvious effect were 85.47% and 86.20% respectively in the treatment group B, and the total response rates were 97.45% and 97.41% respectively. In the control group, the rates of total obvious effect both were 72.57%, and the total response rates both were 99.12%. There was significant difference among the three groups (P<0.05). The effects of traditional Chinese medicine syndrome were also detected by ITT and PPS analysis respectively. In the treatment group A, the total obvious effect rates were 84.07% and 85.46% respectively, and the total response rates were 96.46% and 97.27% respectively. In the treatment group B, the rates of total obvious effect were 88.89% and 89.65% respectively, and the total response rates were 97.44% and 97.41% respectively. In the control group, the rates of total obvious effect both were 72.57%, and total response rates both were 99.12%. There was also statistical significant difference among the three groups (P<0.05). ITT and PPS analysis had the same results. No adverse effect was found in the trial. CONCLUSION: Yiqing Shuangjie Capsule and Tablet are effective and safe in treating acute upper respiratory tract infection of wind heat syndrome without obvious adverse effect.

Objective To investigate the relationship between thyroid nodules with calcification and thyroid carcinoma and its significance in the screening of thyroid carcinoma in high risk group.Methods The clinical data of 1771 patient undergoing surgery for thyroid nodules from March, 2006 to March, 2009 in Huashan Hospital, Fudan University were retrospectively analyzed. Results Among 1771 patients, 500 were finally identified as having malignant tumors. Incidence of calcification in thyroid carcinoma was 68. 4%, and that in benign thyroid nodules was 27.0% ( χ2 = 259. 5, P ＜ 0. 05 ). The specificity of microcalcification for the diagnosis of carcinoma was 89. 4%, and its positive predictive value was 66. 3% ( χ2 = 368.6, P ＜ 0. 01 ). The incidence of thyroid carcinoma in patients ＜ 45 years was 39.2%, while that in patients ≥ 45 years was 22.9% ( χ2 = 51.12, P ＜ 0. 05 ). The incidence of carcinoma in patients of single thyroid nodule was 31.7% and that in those with multiple nodules was 26. 4% (χ2 =4. 766,P ＜ 0. 05). Metastasis was pathologically diagnosed in 26. 8% of lymph nodes found by preoperative ultrasonography. Conclusions The specificity of thyroid nodule calcification, especially microcalcification is high for the diagnosis of thyroid carcinoma. High-risk index for carcinoma includes thyroid nodules with microcalcification, ＜ 45 years old and single thyroid nodule.

This study is to investigate the authenticity between COLD and HOT natural attribute in the famous Chinese medicine formulas--Zuojinwan (Coptis-Evodia 6 : 1) and Fanzuojinwan (Coptis-Evodia 1 : 6) based on mice temperature tropism, and establish an objective method to estimate the difference of two natural attribute by using a cold/hot plate differentiating technology. The results indicated that the COLD nature Zuojinwan could decrease significantly the remaining rate of HOT-symptom rat on warm pad (P < 0.05). That was not notable to COLD-symptom rat. The interference result of COLD-HOT temperature tropism to COLD/HOT symptom rat in Fanzuojinwan was the reverse with the COLD nature Zuojinwan. Meanwhile, biochemical indicators which are relative to energy metabolism such as ATPase enzyme activity and total anti-oxidant capability (T-AOC), had corresponding change in the organism. In the study, the COLD and HOT natural tendency in Zuojinwan and Fanzuojinwan which were composed by the same herbs with different proportion could be expressed qualitatively, quantitatively, objectively and directly with applying animal temperature tropism, and be verified to philosophical idea of treating disease theory with "expelling heat with cold herbs and cryopathy requiring warm prescription", not "expelling heat with heat herbs and cryopathy requiring cold prescription" in ancient traditional Chinese medicine, which brings a new approach in investigation of the nature theory of traditional Chinese medicine.
