Objective To observe the ultrastructure location of Huntingtin-associated protein 1(HAP1) in rat adrenal medulla and the effect of cold stress on the expression of HAP1 in rat adrenal medulla. Methods Fourteen healthy male Wistar rats were used in the present study and among them two rats were used for immune electron microscopy and twelve rats for cold stress experiment. In the cold stress experiment, animals were divided into control and cold groups randomly with six rats in each group. During the experiment, rats were housed in a room at the temperature of 4℃ for 12 hours and then immunohistochemistry and Western blotting were used to measure the expression of HAP1 in adrenal medulla. Results By using the immune electron microscopy, the results showed HAP1 was located on the external membrane of secretory vesicles of adrenal medulla and their membranous organelles. The expression of HAP1 in adrenal medulla of cold group significantly decreased as compared with that of control group ( P <0.01). Conclusion HAP1 might be related with the adrenal medulla cells endocrine granula and involved in the transmission and release of adrenaline or noradrenaline in secretory granule.

Objective To observe the safety and efficacy of ultrasound-guided radiofrequency ablation(RFA)with artificial pleural effusion for cancer of the liver located under the diaphragm.Method Fifteen lesions in 11 patients with cancer of the liver located under the diaphragm were treated by RFA with artificial pleural effusion,for which 500-1000 ml normal saline was injected into the pleural cavity.Results Artificial pleural effusion was finished successfully,the whole tumor for all of 15 lesions were visualized by ultrasound and the ideal puncture pathway were easy to find.The artificial pleural effusion was vanished within 1 week after operation.All of the lesions were treated with RFA and complete necrosis was obtained in 13(86.7%)of the 15 lesions by CT or MRI.No severe complication was observed.Conclusion RFA with artificial pleural effusion is a safe and effective treatment option for patients with liver cancer under the diaphragm.

Objective To study the changes of microarchitecture, bone mineral density (BMD) , and bone mineral content (BMC) in apolipoprtein E knockout( ApoE-/-) mice. Methods Male ApoE-/- mice at 15, 28, and 40-week of age and sex-age-matched wild-type (WT) mice were involved in the study. The trabecular and cortical bone microarchitecture were assessed by micro-CT( μCT) in the right distal femur. The total body BMD of the left femur was determined by dual-energy X-ray absorptiometry ( DXA). The relationships among BMD, microarchitecture, and BMC were analyzed. Results Compared with WT mice,the advancing age ApoE-/- mice showed an increased volumetric BMD (vBMD), tissue BMD (tBMD) , BMC, bone volume fraction (BV/TV), trabecular number (Tb. N ) , trabecular thickness (Tb. Th) with an decreased bone surface fraction ( BS/BV), trabecular separation (Tb. SP) , and the structure mode index (P <0. 05 ) in the cancellous bone of femur. The cortical bone microarchitecture parameters as inner perimeter, outer perimeter, cortical area, marrow area, total area and moment of inertia were also increased, but cortical BMD, cortical bone mineral content (C. BMC) and cortical thickness retained constant. At the age of 28 weeks,the total body BMD in ApoEE-/- mice revealed higher than WT mice (P<0. 05) and there was no changes in 15 and 40-week-old mice compared with the sex-age-matched controls. vBMD was positively correlated with BMC, BV/TV,Tb. Th, BS/BV, and C. BMC, with the correlation coefficients 0.955,0.944,0. 834,0.923, and 0.903 .respectively, and there was no correlation between vBMD and the other parameters. Conclusions ApoEE-/- mice display an increased bone mass, suggesting that ApoE has an important role in bone remodeling.

Objective To understand non stomatology undergraduates'strategies for learning stomatology and to study the reform on this course.Methods The learning strategies of 560 undergraduates majoring in clinical medicine from grade 2007 were investigated s and ten related factors like learning attitudes were investigated by learning strategies scale.Correlation analysis and linear regression analysis were applied to deal with research data.Results Most undergraduates were lack of strategies in learning stomatology.Related coefficient between 10 factors and academic scores ranged from 0.197 to 0.401,existing positive correlation(P＜0.05).Determination coefficients(R2)of attitude,motivation,time management and learning auxiliary means were 0.146,0.167,0.223and 0.122 respectively,which can be used to predict the scores of examination.Condusions Non stomatology undergraduates'strategies for learning stomatology is a vital factor influencing their academic scores.It's necessary for teachers to improve their teaching methods considering students'professional characteristics and learning strategies.

Objective To research the resilience and related factors of the rescue soldiers. Methods Resilience Scale for Adults( RSA ), Self-report Symptom Checklist 90 (SCL-90), Eysenck Personality Questionnaire(EPQ) and Coping Style Questionnaire were applied in this survey to 1401 rescue soldiers. Results ①The soldiers' resilience score was (2.49±0.57) ,significantly lower than college students( t= 16.619, P=0. 000).The rescue soldiers with the year in army above 3 were significantly higher than that below 2 years in social competence( t=2.581, P=0.01 ) ,social resources( t=2. 158, P=0.031 ) ,structured style( t=3.254, P=0.001 ) and RSA scores(t=2.455, P=0.014). There exist significantly differences in various education level of the rescue soldiers in perception of self(t=3.732, P=0.024), planned of future ( t = 9.324, P = 0.000 ) , social competence ( t = 8. 838, P = 0.000 ), social resources ( t = 13. 660, P = 0. 000 ) and RSA scores (t=9.805, P=0.000) , and college ≥ senior high school ≥ junior high school. ②Compared to the lower group in the RSA, the higher group scored significantly higher in extraversion (t=16. 204, P=0.000) and positive coping( t = - 18. 171, P=0.000), while lower in SCL-90 (t=8.461, P=0.000) and neuroticism (t=8.833, P=0.000 ).③Resilience have the obvious positive correlation with the education ( r= 0. 116 ), extraversion ( r= 0. 463 ) and positive coping(r=0.500) ,and negative correlation with the neuroticism(r=-0.251 ) and SCL-90( r= -0.260). It can be assumed that positive coping,extraversion and neuroticism had good predictive ability(35.9％) to resilience. Conclusion The rescue soldiers have low resilience than college students, positive coping, extraversion, and neuroticism are important psychological factors for rescue soldiers.

BACKGROUND: The study aimed to estimate the value of embryonal natural orifice transluminal endoscopic surgery (ENOTES) in treating severe acute pancreatitis (SAP) complicated with abdominal compartment syndrome (ACS). METHODS: The patients, who were randomized into an ENOTES group and an operative group, underwent ENOTES and laparotomy, respectively. The results and complications of the two groups were compared. RESULTS: Enterocinesia was observed earlier in the ENOTES group than in the operative group. Acute Physiology and Chronic Health Evaluation II (APACHE II) score of patients in the ENOTES group was lower than that of the operative group on the 1st, 3rd and 5th post-operative day (P<0.05). The cure rate was 96.87％ in the ENOTES group, which was statistically different from 78.12％ in the operative group (P<0.05). There were significant differences in complications and mortality between the two groups (P<0.01). CONCLUSION: Compared with surgical decompression, ENOTES associated with flexible endoscope therapy is an effective and minimal invasive procedure with less complications.

Objective To investigate the relationship between absent or hypoplastic fetal nasal bone and chromosome abnormalities.Methods From January 2010 to April 2014,187 fetuses were found to have absent or hypoplastic nasal bone by prenatal ultrasound scanning in Guangzhou Maternal and Children's Hospital.All the pregnant women should undergo interventional prenatal diagnosis for fetal chromosome abnormalities,and should be followed up for three months after the expected delivery date.The correlation between absent or hypoplastic fetal nasal bone and chromosome abnormalities,and the effects of complicating structural defects were analyzed by descriptive analysis and the Chi-square test.Results Of the 187 pregnant women,126 underwent interventional prenatal diagnostic tests,and fetal chromosome abnormalities were detected in 36 cases (28.6％),including 26 cases (20.6％) of trisomy 21,6 cases (4.8％) of trisomy 18,three cases (2.4％) of trisomy 13 and one sex chromosome chimerism.In the 126 cases received prenatal diagnosis,the incidence of chromosome abnormalities in fetuses without other structural defects was significantly lower than that with structural defects [12.7％ (8/63) vs 44.4％ (28/63),x2=15.556,P=0.000].Among 63 cases without other structural defects,seven fetuses were confirmed to have chromosome abnormalities in 14 women with high risk by Down syndrome screening,no chromosome abnormalities were found in 39 pregnant women with low risk by Down syndrome screening,and one sex chromosome chimerism was found in the other ten women who did not undergo Down syndrome screening.Absent or hypoplastic nasal bone detected in the first trimester resulted in a higher risk of chromosome abnormalities than that detected in the second and the third trimester [25.5％ (28/110) vs 10.4％ (8/77),x2=6.613,P=0.007].Conclusions When a fetus is found to have absent or hypoplastic nasal bone,it is necessary to perform Down syndrome screening and a detailed morphology scan.Women shown to have fetuses with absent or hypoplastic nasal bone with other structural defects or high risk by Down syndrome screening should undergo prenatal diagnostic tests to exclude fetal chromosome abnormalities.
