Objective To explore the associations between microsatellites in gonadal receptor genes and dysfunctional attitudes in adolescent with major depressive disorder(MDD).Methods Polymerase chain reaction(PCR),capillary electrophoresis and genetic scanning were performed in testing the length of microsatellites in first-onset adolescent depressive patients.Dysfunctional attitudes scale(DAS) was used in rating the dysfunctional cognition of adolescent depressive sample.These results were tested by correlative analysis and comparison analysis.Results 1.There existed significantly negative correlation between microsatellite′s length in estrogen receptor ?(ER?) gene and total score of DAS in female adolescent patients with first-onset depressive disorder.2.DAS′ total score of shorter alleles′ group was significantly higher than that of longer alleles′ group on female′ estrogen receptor ?(ER?) Gene.Conclusion The microsatellite′s length of ER? and ER? gene may have associations with dysfunctional attitudes of female adolescent with MDD.

In order to quantitate the bovine immunodeficiency virus (BIV) infection in vitro, a BIV indicator cell line (BIVL) was established by transfecting baby hamster kidney cells with reporter plasmids containing the firefly luciferase gene driven by a BIV long terminal repeat promoter. The BIV activates promoter activity of the LTR to express luciferase upon infection. BIV infection could therefore by quantified by detection of luciferase activity. Compared to standard assays used to detect BIV infection, the BIVL-based assay is 10 times more sensitive than the the CPE-based assay, and has similar sensitivity with the viral capsid protein Western blot assay. BIV indicator cell line could detect BIV infection specifically. Luciferase activity of BIV infected BIVL cells showed a time dependent manner, and 60 h post infection is the optimal time to detect BIV infection. Luciferase activity of BIVL cells correlates with the BIV capsid protein expression. Moreover, a linear relationship was found between MOI and the activated intensity of luciferase expression. In brief, the BIV indicator cell line is an easy, robust and quantitive method for monitoring BIV infection.

Objective: To explore the effect of impaired cardiac microvascular endothelial cells on rat's embryo cardiomyocyte apoptosis and the impact of Tongxinluo in such process. Methods: 3 kinds conditioned medium of cardiac microvascular endothelial cells were prepared. ① normal rat's cardiac microvascular endothelial cell (RCMECs) conditioned medium, ②homocysteine induced impaired RCMECs conditioned medium and ③ Tongxinluo treated RCMECs conditioned medium. Rat's embryo H9c2 cardiomyocytes were divided into 4 groups:① Control group, cells were cultured in DMEM without serum, ② N-CM group, cells were cultured in RCMECs conditioned medium, ③ H-CM group, cells were cultured in homocysteine induced impaired RCMECs conditioned medium and ④ T-CM group, cells were cultured in Tongxinluo treated RCMECs conditioned medium. Cell mitochondrial membrane potential (MMP) was detected by JC-1 agent, ROS level was examined by flow cytometry, cardiomyocytes apoptosis was measured by live cell imaging system, expression levels of cytochrome C (Cyt-C), cysteinyl aspartate specific proteinase-3 (Caspase-3), Bcl-2 associated X protein (Bax) and B-cell leukemia/lymphoma 2 protein (Bcl-2) were detected by Western blot analysis. Results: MMP, expression levels of ROS, Cyt-C and cardiomyocyte apoptosis were similar between Control group and N-CM group, P>0.05. Compared with N-CM group, H-CM group had decreased MMP, increased ROS and cardiomyocyte apoptosis, up-regulated expressions of Cyt-C, Caspase-3 and Bax, all P<0.01. Compared with H-CM group, T-CM group had increased MMP, decreased ROS and cardiomyocyte apoptosis, down regulated expressions of Cyt-C, Caspase-3 and Bax, all P<0.05; while up-regulated expression of Bcl-2, P<0.01. Conclusion: Conditioned medium of impaired cardiac microvascular endothelial cells may induce cardiomyocyte apoptosis and such process could be inhibited by Tongxinluo.

Objective To study the clinical efficacy of caffeine in premature infants receiving mechanical ventilation and related complications .Method From January 2014 to September 2016, preterm infants (28w≤GA<33w) treated with nasal continuous positive airway pressure (NCPAP) or conventional mechanical ventilation ( CMV ) in neonatal intensive care unit were studied .They were randomly assigned into the caffeine group and the control group .The caffeine group received caffeine when NCPAP ventilation was applied or adjusting to synchronized intermittent mandatory ventilation ( SIMV) mode.The control group was injected with 5%glucose without caffeine .The t test andχ2 test were used to analyze the clinical efficacy and related complications .Result A total of 96 patients receiving NCPAP ventilation were collected ( birth weight between 1300~2100 g), including 51 cases in caffeine group and 45 cases in the control group. 84 cases received CMV ventilation (birth weight between 1000~1499 g), with 43 cases in the caffeine group and 41 cases the control group.Among the NCPAP infants, the incidence of failure to withdraw ventilator (0% vs.13.3%) and the incidence of bronchopulmonary dysplasia (3.9% vs.17.8%) were lower in the caffeine group than the control group .The duration of assisted ventilation and hospital stay in the caffeine group were shorter than the control group [(6.2 ±3.1) d vs.(8.2 ±3.2) d, (16.3 ±8.7) d vs. (19.5 ±9.2) d], the differences were statistically significant (P<0.05).Among the CMV infants, the incidence of failure of A/C to SIMV mode transition and bronchopulmonary dysplasia were lower in the caffeine group than the control group and the duration of assisted ventilation and hospital stay were shorter . The differences were statistically significant ( P <0.05 ) . No differences were found in the related complications in each group ( P>0.05) . Conclusion Caffeine can help reduce the incidences of withdrawal failure, bronchopulmonary dysplasia , ventilation duration and hospital stay when using NCPAP and CMV ventilation.

Objective To assese the healing of stoma after magnetic anastomosis for the reconstruction of biliary-enteric continuity under severe inflammation.
Methods Acute bile duct injury was constructed as a bile peritonitis model in mongrel dogs (n=32). Magnetic anastomosis (group A, n=16) and traditional suture anastomosis (group B, n=16) were performed to reconstruct the biliary-enteric continuity in one stage. Half of the dogs in each group were euthanized on the 30th postoperative day, and the other half on the 90th postoperative day to harvest the stoma region. The healing conditions of the stoma after the 2 anastomotic approaches were observed with naked eyes, under light microscope and scanning electron microscope.
Results The stoma leakage rate (50%versus 0%on the 30th postoperative day, 37.5%versus 12.5%on the 90th postoperative day, both P<0.05) and stenosis degree (13.9%±0.3%versus 7.1%±0.3%on the 30th postoperative day, 17.2%±0.4%versus 9.4%±0.4%on the 90th postoperative day, both P<0.01) were significantly higher in group B than in group A. Compared with traditional manual anastomoses, the histological analysis under light and electron microscope showed a more continuous stoma with more regular epithelium proliferation and collagen arrangement, less inflammation in group A.
Conclusions Magnetic anastomosis stent ensures better healing of the stoma even under the circumstance of severe inflammation.

OBJECTIVETo investigate the role of B7-H1 expression in IL-10 production, the B7-H1 and IL-10 expression levels in pancreatic carcinoma tissues and to analyze the correlation between B7-H1 expression and IL-10 level.

METHODSThe mRNA and protein levels expressions of B7-H1 and IL-10 in 35 cases of pancreatic cancer and corresponding paracarcinoma tissues and 5 cases of normal pancreas tissues were detected by RT-PCR, Western blot and immunohistochemistry respectively.

RESULTSThe findings for the first time provided the evidences that there was a clear trend for B7-H1 and IL-10 expressions to be most highly expressed in carcinoma tissue, intermediately expressed in paracarcinoma tissue, and expressed at the lowest level in normal pancreatic tissue at mRNA and protein levels. Moreover, there were statistically significant differences in B7-H1 and IL-10 expression between pancreatic carcinoma tissues, corresponding paracarcinoma tissues and normal pancreatic tissues at mRNA and protein levels (P < 0.05). Furthermore, the immunohistochemistry indicated that there were high expression levels of B7-H1 (60.5% +/- 12.7%) and IL-10 (65.3% +/- 16.2%) in pancreatic carcinoma tissues while there were no significant expressions in normal pancreatic tissues. Meanwhile, correlation analysis revealed that B7-H1 expression was significant associated with IL-10 level in tumor tissues at mRNA (P = 0.008, r = 0.841) and protein levels (P = 0.007, r = 0.838).

CONCLUSIONSOver-expression of B7-H1 may be responsible for the increasing IL-10 production in pancreatic cancer, which caused reduced immune response to tumor cells and contributed to pancreatic carcinoma escape from immune attack.
