Chinese Journal of Behavioral Medicine and Brain Science 2013;(6):550-552
Objective To study the impact of gender,gender role and gender traits on depression in adolescents.Methods A sample of 1330 middle school students from seven provinces in China completed Beck Depression Inventory (BDI) and Gender Traits Inventory.Results 27.1 percents of participants displayed the symptoms of depression.The mean score of males of BDI was 10.04 ± 8.38 while that of females was 10.33 ± 8.37,indicating that there was no sex differences in depression of adolescents(P=0.535).The participants could be classified into 4 sex role types:masculine,feminine,androgynous and undifferentiated,and the BDI mean score of each type was 9.51 ± 7.66,12.30 ± 8.81,9.14 ± 8.10,10.72 ± 8.66,and significant differences were found among adolescents with different gender roles (P =0.000).BDI scores of the feminine adolescents were the highest among the four gender roles,which were significantly higher than scores of the masculine and androgynous adolescents (P =0.000).Regression analysis indicated that adolescents with more positive masculine traits tended to be less depressive (t =-4.966,P < 0.01) while adolescents with more negative masculine (t =2.574,P < 0.01) or feminine (t =10.566,P < 0.01)traits tended to be more depressive.Conclusion Gender role rather than gender has greater impacts on adolescent depression,and specifically,positive masculine traits represent protective factors for depression.

AIM: To study the instant effect of circumstance temperature on mechanical properties of single living intact human red blood cell. METHODS: The shape, size, membrane bending elastic modulus and shear elastic modulus of single living intact red blood cell was determined with non-invasive, in situ, real time by employing a static micro-image analyzing and a dynamic micro-image analyzing system. RESULTS: The contact area and diameter of red blood cells were decreased as the temperature increased from 35 ℃ to 43 ℃. The membrane bending elastic modulus and shear elastic modulus of single living intact red blood cell were the least at physiological temperature 37 ℃. CONCLUSION: Red blood cells are easy to carry out their physiological functions such as carrying oxygen to all of the body with the best shape and mechanical deformation at 37 ℃.

BACKGROUND: Body temperature has significant effects on brainstem auditory evoked potentials (BAEP). The wave latency of BAEP is the sensitive and objective index for reflecting the effects of body temperature on the synaptic transmission and nerve fiber conduction. The wave origin of electrocochleogram (ECochG) and the effects of body temperature on it need to be probed into to further define its wave origin so as to guide its clinical application.OBJECTIVE: To observe the effects of body temperature on ECochG and provide important basis for further defining its wave origin and guiding its clinical application.DESIGN: A randomized block design.MATERIALS: This study was performed in the Department of Physiology, Medical College of Jinan University between July and September 2002. Forty adult guinea pigs were randomly divided into hypothermia group (n=20) and hyperthermia group (n=20).INTERVENTIONS: The body temperature of the guinea pigs was decreased or increased step by step with their body contacted with physical method. and the changed rate of body temperature was kept as decreased or increased by 1 ℃ every 5-10 minutes. BAEP and ECochG were detected when the body temperature was changed by 1 ℃.MAIN OUTCOME MEASURES: The PL and IPL of BAEP and ECochG were observed.RESULTS: Finally, 37 guinea pigs were involved in the analysis of relonged as the body temperature was decreased step by step from 36 ℃ to 25 ℃, and shortened as the body temperature was increased gradually from 36 ℃ to 42 ℃. The PL and Ⅰ-Ⅳ IPL prolonged or shortened more significantly with the temperature changed. The PL of wave N1, N2 and N3 and N1-N3 IPL of ECochG also prolonged or shortened as the body temperature perature,the total prolonged and shortened values of Ⅰ -Ⅳ IPL representing the central transmission time of brainstem were much greater than that of wave Ⅰ PL representing the peripheral conduction time, .and the total prolonged and shortened values of thePL of wave Ⅱ , Ⅲ and Ⅳ originating from the brainstem centers were much greater than that of wave Ⅰ originating fromthe auditory nerve. The total prolonged and shortened values of N1-N3 IPL were greater than that of wave N1 PL representing the peripheral conduction time, and the total prolonged and shortened values of the PL of wave N2 and N3 were much greater than that of wave N1 originating from the auditorynerve.CONCLUSION: The significant effects of body temperature on ECochG are similar to those of BAEP, and the origin of wave N2 and N3 of ECochG is higher than that of wave N1 that originates from the auditory nerve.

Objective To investigate the diagnosis and management of pancreatic injury. Methods The clinical data of 23 patients suffering from pancreatic injury treated by surgery in recent 15 years were analyzed retrospectively. According to the pancreas organ injury scale of the American Association for the Surgery of Trauma, there were 8 cases in grade I, 8 in grade II, 5 in grade III, 1 in grade IV and 1 in grade V. Results Only 2 patients were diagnosed preoperatively out of the 19 patients.About 63.2%(12/19)of the cases had elevated levels of serum amylase. All the patients were cured.In this series,8 cases occurred external pancreatic fistula, 4 pseudocysts, 2 intra-abdominal infections and 1 hyperglycemia postoperatively. Internal pancreatic fistulas were found in all the non operation patients. Conclusions The serum amylase determinations is neither sensitive nor specific for diagnosis of pancreatic injury. Early diagnosis and correct operative pracedure are important to decrease the postoperative complications and improve the outcome.

2 cm) according to the size of lesions. Large wound sections were sutured with metal clips. Results Histopathologic investigation showed that among 54 lesions,there were 13 cases of adenoma,38 cases of adenoma with atypical hyperplasia (10 cases with mild dysplasia,23 with moderate dysplasia and 5 with severe dysplasia )and 3 cases of mucosal cancer. We followed forty cases,local recurrence was found in none of 29 cases after 6 months of EMR. However,the recurrence was found in 2 of 11 cases after 1 month of EPMR and 1 each after 3 and 6 month of EPMR. There was no recurrence after further endoscopic re-treatment. Among 3 cancer patients,2 patients shifted to surgery due to patient's preference and 1 patient was followed up for 6 months. All of them were found without local recurrence by endoscopic biopsies or surgical results. Conclusions Chromoscopy,magnifying colonoscopy and EUS have benefits in diagnosis of early large bowel tumors,and it is also helpful in selecting the proper treatment so as to reduce the complication and recurrence.
