Objective To examine the effect of family environment and family function on suicide behavior in schizophrenic patients.Methods 53 schizophrenic patients with suicidal behavior in the last month were selected for the schizophrenic suicide group.53 schizophrenic patients and 53 normal controls matched with the schizophrenic suicide group were selected for the schizophrenic no suicide group and normal control group.All of them completed family environment scale and family assessment device.Results The cohesion factor,the expressiveness factor,the active-recreational orientation factor and the control factor of family environment scale in the schizophrenic suicide group were significant lower than those in the schizophrenic without suicide group(separately 5.70 ± 1.29 vs 6.62± 1.23,4.77 ± 1.49 vs 5.96 ± 1.11,3.94 ± 1.63 vs 5.68 ± 1.98,2.68 ± 1.68 vs 4.40 ± 1.81,P＜ 0.05),but the conflict factor in the schizophrenic suicide group was higher than in the schizophrenic without suicide group(3.55 ± 1.60 vs 2.81 ± 1.52,P ＜ 0.05).The affective responsiveness factor,the affective involvement factor and the behavior control factor of family assessment device in the schizophrenic suicide group were significant lower than those in the schizophrenic without suicide group(separately 16.05 ± 2.57 vs 14.53 ± 3.38,19.13 ± 4.09 vs 16.58 ± 2.82,23.35 ± 3.52 vs 21.60 ± 3.25,P ＜ 0.05).Multiple liner regression analyses showed that the expressiveness factor,the active-recreational orientation factor,the control factor,the affective involvement factor and the behavior control factor were important factors for schizophrenic suicide(F=21.583,P=0.000,adjusted R 2 =0.519).Conclusion Attempted suicide patients with schizophrenia have some deficiencies at family function and family environment.

Objective: To investigate the induction of Tca8113 cells to apoptosis by fadd gene.Methods: RT PCR and recombinant PCR were used to amplify human fadd gene and cloned into expression vector pcDNA3 and pIRES2 EGFP, then transfered into Tca8113 cells. The growth and apoptosis of the cells were tested by cell counting,fluorescent microscopy, electron microscopy and flow cytometery. Results: fadd gene was obtained and transfered into Tca8113 cells. After transfection of the gene the growth of the cells was inhibited by 25%～52%, cell number in G 1 phase increased and that in S phase decreased. Apoptosis of the cells was observed. Conclusion: fadd gene can effectively inhibite cell growth and induce Tca8113 cells to apoptosis.

Objective To retrospectively review clinical results of combined coronary artery bypass grafting (CABG) and other heart surgical procedures.Methods Combined CABG and other heart surgical procedures have been done in 134 consecutive cases (male 114, female 20), aged from 48 to 76 years with a mean of 61.7. Coronary angiograph showed that all patients have coronary stenosis with left main involved in 20 cases, and 41 cases have diffused coronary artery disease. 56 patients have post myocardial infarction left ventrical aneurysms, and 42 patients have valve dysfunction which need surgical correction. Left ventricular ejection fraction (EF) were equal to or lower than 45% in 63 patients and in 13 patients EF is less than 30%. All the patients received combined CABG under the support of cardiopulmonary bypass (CPB) and other heart surgical procedures (Transmyocardial laser revascularization in 36, valve procedures in 42, and left ventricle aneurysm resection or plasty in 56 patients simultaneously). Results The mean number of grafts was 2.46 per patient. Intra-aortic balloon pump was required in 6 cases for 11 to 54 hours Postoperative. 3 patients died postoperatively with mortality rate 2.2% (two from low cardiac output syndrome, and one from multiple organs failure). 131 patients recovered and discharged.Conclusion Combined CABG and other heart surgical procedures in more demanding than CABG along but can be done with acceptable morbidity and mortality if good surgical plan can be designed and all the heart abnormalities can be corrected simultaneously.

Objective To investigate the difference of clinical efficiency and safety in obsessive-compulsive disorders (OCD) treatment with escitalopram or paroxetine.Methods A total of 156 OCD patients were randomly divided into escitalopram group (ESC group) and paroxetine group (PAR group).Yale-Brown Obsessive Compulsive Scale (Y-BOCS),Hamilton Depression Scale (HAMD) and Treatment Emergent Symptom Scale (TESS)were used to evaluate the clinical efficiency and safety before and after1,2,4,6,8 weeks treatment.Results The cure rate(21.79％ vs 17.95％) and effective rate(70.51％ vs 71.79％) had no statistically difference between ESC group and PAR group,and incidence of side effect had no significant difference between two groups(x2 =1.99,P＞0.05).Compared with the group before treatment,HAMD scores were significantly decreased from the first weekend in ESC group,but in PAR group HAMD scores did not decrease until the second weekend,and the differences were also significant(P＜0.05).Conclusion Escitalopram is a safety,effective and well-tolerated drug in the treatment of obsessive-compulsive disorder.

The superficial middle cerebral veins (SMCV) of 50 human heads were dissectedunder the operating microscope (10?).There were 122 terminal braches of the SMCV in the specimens and the typesof their drainage can be divided into four:type 1 (41.00%)—drains into the caver-nous sinus;type 2 (24.60%)—drains into the variant venous sinus in the lateralwall of the cavernous sinus;type 3(28.70%)—drains into the variant venous sinus inthe dura of the middle cranial fossa;type 4(5.70%)—drains into other dural venoussinuses.Type 1 may be considered as normal and the others as variant.The two variant dural venous sinuses reported are respectively located in thelateral wall of the cavernous sinus,named“the lateral wall sinus of the cavernoussinus”,and in the dura of the middle cranial fossa,named the“variant sinus ofthe middle cranial fossa”.The former occurred 27% in the specimens and the later25%.We have discussed about the drainage of the SMCV and two variant dural ven-ous sinuses on the embryonic basis and the clinical practice.

Objective To explore the targeting homing capacity of bone-marrow derived mesenchymal stem eells(MSCs) on rabbit myocardial ischemia by intravenous injection of MSCs under the mediation of diagnostic ultrasound and microbubble. Methods Density gradient centrifugation and adherent culture method were used in the isolation and cultivation of MSCs. MSCs were labeled with DAPI. Rabbit myocardial infarction(MI) models were builded by totally ligation of left anterior descending branch of coronary artery. DAPI labeled MSCs were implanted by intravenous injection with or without the mediation of diagnostic ultrasound and microbubbles. Forty-eight hours after cell transplantation, the hearts of MI rabbits were made of frozen section and observed under fluorescent microscope. The DAPI positive cells were counted in the MI and border area of rabbit heart and compared between two groups. Pathological changes of MI area were observed with HE staining under light microscope and transmission electronic microscope. Results The number of DAPI positive cells in MI and border area of rabbit in both groups were counted under fluorescent microscope. There were more DAPI positive cells in the MI area in ultrasound + microbubble + MSCs group (213.2±26.5) than that in the intravenous injection group (146.8±18.78, P<0.01). There were erythrocytes leaking out of the vessels in MI area in HE staining section under light microscope in ultrasound + microbubble + MSCs group while there were nearly none in the intravenous injection MSCs group. The intercellular space of endothelial cells of the vessels wall was increased and serum component leaked out of the vessel wall in ultrasound + microbubble + MSCs under transmission electronic microscope. Conclusions The targeted homing capacity of BM-MSCs in the MI area of rabbit heart can be enhanced under the mediation of diagnostic ultrasound and microbubbles.

Purpose: To probe the effect and mechanism of androgen receptor antagonist MDV3100 on benign prostatic hyperplasia (BPH) of rats Methods: BPH rat model was induced by testosterone propionate. Then antagomir-miR-21-3p or agomir-miR-21-3p was injected into rats before MDV3100 treatment. The prostate index was measured by weighing the wet weight of the rat prostate. The structural morphology of rat prostate was observed after hematoxylin & eosin staining. Immunohistochemistry was applied to evaluate the expression levels of Ki-6 and inflammatory cytokines (interleukin [IL]-6, IL-18, and tumor necrosis factor-α) in rat prostate tissues. Quantitative reverse transcription polymerase chain reaction was utilized for assessment of miR-21-3p expression, and Western blot for the performance of the phosphorylation levels of IKKα and p65. Results: Injection of testosterone propionate caused increased prostate gland hyperplasia, heightened miR-21-3p level, and activated nuclear factor-kappa B (NF-κB) signaling pathway. Additionally, BPH was accompanied by inflammatory response, as evidenced by enhanced expressions of Ki-67 and inflammatory cytokines. MDV3100 exposure ameliorated BPH and suppressed miR-21-3p expression. Overexpression of miR-21-3p intensified BPH and inflammation level, while knockdown of miR-21-3p relieved BPH. The coeffect of miR-21-3p upregulation and MDV3100 subjection led to higher inflammatory response, elevated phosphorylation levels of IKKα and p65 than MDV3100 treatment alone. Conclusions Androgen receptor antagonist MDV3100 alleviates BPH and inflammatory response through miR-21-3p downregulation and NF-κB signaling pathway blockade.

Objective To explore the value of diagnostic ultrasound mediated microbubble destruction in improving the myocardial perfusion and left ventricular systolic function when cooperated with the mecsenchymal stem cells(MSCs) transplantation in rabbit myocardial ischemia. Methods One week after myocardial ischemia (MI) modeling,36 rabbits were divided into 3 groups,the control group(group Ⅰ) ,intravenous injection of MSCs group(group Ⅱ) and ultrasound + microbubble + MSCs group (group Ⅲ). Myocardial contrast enhancement (MCE) was performed and quantification analysis of anterior wall was assessed with Photoshop. Left ventrieular systolic function was assessed with M-mode echocardiography and bi-plane Simpson's method. CD34 expression in heart was detected with immunohistochemisty(IHC). Western blotting was applied to detect the level of VEGF in three groups. Results The differences of gray scale analyzed with histogram of Photoshop in anterior wall of ischemia myocardium between the group Ⅰ and group Ⅱ or group Ⅲ were significant,and P value was 0. 032 and 0. 000 , respectively. There were significant differences of FS between group Ⅲ (30. 43±4.09)% and group Ⅱ (26.29±2.93)%, P<0.01, and similar to group Ⅰ (19.28 ± 2.84)%. The difference of EF(%) between group Ⅲ and group Ⅱ was significant [(61.5±5.8 vs 53.6±4. 71), P<0. 05] ,or markedly significant between group Ⅲ and group Ⅰ [(61.5±5.8 vs 42.6± 5.0), P <0.01]. EF(%) assessed with bi-plane Simpson's method was significantly increased from (34.64 ± 4.59) in group Ⅰ to (41.78 ± 4.21) in group Ⅱ and (48.6±3.96) in group Ⅲ. The expression of CD34 assessed with immunohistochemistry was the highest in group Ⅲ. The level of VEGF with western blotting in group Ⅲ was significantly higher than other two groups. Conclusions It is an efficacious transplantation means of MSCs infusion under the ultrasound mediated microbubles destruction in improving the myocardial perfusion and cardiac systolic function.
