Objective: To investigate influence of Wenxin particle on cardiac electrophysiology in rats complicated with depression after myocardial infarction (MI). Methods: A total of 50 SD rats were randomly and equally divided into normal group, MI group, depression group, MI complicated with depression group (model group) and Wenxin particle group (Wenxin particle were given to model rats by gavage, 2 g/d, 28d). Model（MI complicated with depression）rats were made by acute ligation of left coronary artery and supply chronic unpredictable mild stress in order. The influences of Wenxin particle on cardiac electrophysiological indexes, such as monophasic action potential (MAP90), left ventricular effective refractory period (ERP) and ventricular fibrillation threshold (VFT) were evaluated in Wenxin particle group. Results: (1) Compared with normal group, there were significant decrease in behavior scores (P<0.05) in model group, after four-week treatment with Wenxin particle, their behavior scores significantly increased (P<0.01); (2) Compared with normal group, there were significant increase in MAPD90 and ERP, and significant decrease in VFT in model group (P<0.05); compared with model group, there were significant decrease in MAPD90 [(89.33±7.12) ms vs. (72.29±8.37) ms] and ERP [(84.00±6.57) ms vs. (68.00±7.43) ms], and significant increase in VFT [(7±3.11)V vs. (29±5.60)V] in Wenxin particle group, P<0.05. Conclusion: Wenxin particle can improve cardiac electrical remodeling in rats complicated with depression after myocardial infarction, including decrease monophasic action potential duration and effective refractory period, and raise ventricular fibrillation threshold.

Objective To summarize the experience of orthotopic liver transplantation in pigs without veno-venous bypass.Method In general,Bama miniature pigs were used as both the donors and the recipients.Suprahepatic inferior vena cava and portal vein anastomosis was performed with running prolene sutures.After completion of the portal vein anastomosis,the graft was reperfused.Infrahepatic inferior vena cava anastomosis and hepatic artery anastomosis were performed in a similar fashion.Finally,the common bile duct was reconstructed.Result For all of the transplant procedures,the average cold ischemic time was 356.3 ± 66.4 min and anhepatic time 22.5 ± 2.6 min,and the average operative time was 185.7 ± 24.8 min.During the anhepatic phase,the central venous pressure (CVP) and the mean arterial pressure (MAP) were significantly lower than those at baseline (P＜ 0.05).Heart rate (HR),on the other hand,was increased significantly during the anhepatic phase (P＜0.05).By the time the portal vein and the hepatic artery were reperfused,and CVP and MAP were gradually elevated,and HR gradually reduced.All receptors were successfully extubated and awake after surgeries.On the third postoperative day they began to eat.All receptors survived during the intraoperative period,and the survival rate was 93.8％ (15/16) on the fifth postoperative day.One receptor was died on the third postoperative day due to abdominal infection.Conclusion This model has satisfactory stability and reproducibility.Without using any vasoactive substances,to maintain the MAP beyond 50 mmHg in the anhepatic phase and the short anhepatic time are important to perform successful liver transplantation.

Objective To discuss the application of transanal placement of ileus tube in treatment of colonic obstruction in left colorectal cancer.Methods Thirty-two patients with left malignant colorectal obstruction were divided into ordinary colonoscope group (16 cases) and superslim endoscope group (16 cases) by random digits table.The catheter success rate,catheter operating time and exposure to X-ray time was compared between two groups.Results Fifteen cases were successful and 1 case was failed in ordinary colonoscope group.Thirteen cases were successful and 3 cases were failed in superslim endoscope group.There was no significant difference in the catheter success rate between two groups (x2 =1.143,P =0.285).The catheter operating time was (42 + 15),(20 +6) min in ordinary colonoscope group and superslim endoscope group,and there was significant difference between two groups (t =3.895,P =0.005).The exposure to X-ray time was (20 + 12),(5 + 2) min,and there was significant difference between two groups (t =-3.596,P =0.007).Conclusion Transanal placement of ileus tube is more successful and convenient by superslim endoscope combined with anesthesia than by ordinary colonoscope.

Objective To explore the effect of fluoxetine on the brain function of bulimia nervosa (BN) patients.Methods Seven female BN patients,who met criteria of the 3rd version Chinese Criteria of Mental Diseases (CCMD-3),accepted functional magnetic resonance imaging (fMRI) examinations before and after the antidepressant treatment (fluoxetine (20 mg/day)) for three months.Seven normal controls accepted the same fMRI examination only at baseline.fMRI imaging was block-design.Blocks of food or non-food stimulus containing pictures selected from International Affective Picture System (IAPS) which were shown by computer automatically.All subjects were evaluated by Hamilton anxiety scale (HAMA),Hamilton depression scale (HAMD17) and Likert Scale-likelihood evaluation to the same pictures in the fMRI imaging blocks.Results The average intensity and volume activated in BN before treatment were both significantly lower than that in the control (P＜0.05).But under stimulus of food pictures,bilateral prefrontal cortex and left amygdala of BN patients were significantly activated.After fluoxetine treatment,the intensity and volume activated both increased significantly (P＜0.01) and the main areas being activated were right temporal,cerebellum and bilateral prefrontal cortex.Conclusion Fluoxetine improves the bulimic symptoms of BN patients and decreases abnormal activation of prefrontal and limbic in these areas.The underline mechanism may be related to functions of serotonin system in prefrontal-limbic path.

OBJECTIVETo evaluate the efficacy and safety of testosterone undecanoate (TU) in the treatment of late-onset hypogonadism (LOH) by meta-analysis.

METHODSWe searched Pubmed (until April 1, 2014), Embase (until March 28, 2014), Cochrane Library (until April 17, 2014), CBM (from January 1, 2001 to February 2, 2014), CNKI (from January 1, 2001 to February 2, 2014), Wanfang Database (from January 1, 2000 to February 2, 2014), and VIP Database (from January 1, 2000 to Febru ary 2, 2014) for randomized controlled trials of TU for the treatment of LOH. We evaluated the quality of the identified literature and performed meta-analysis on the included studies using the Rveman5. 2 software.

RESULTSTotally, 14 studies were included after screening, which involved 1 686 cases. Compared with the placebo and blank control groups, TU treatment significantly increased the levels of serum total testosterone (SMD = 6.22, 95% CI 3.99 to 8.45, P < 0.05) and serum free testosterone (SMD = 4.35, 95% CI 1.86 to 6. 85, P < 0.05) but decreased the contents of luteinizing hormone (WMD = -2.23, 95% CI -4.03 to -0.42, P < 0.05), sex hormone binding globulin (WMD = 2.00, 95% CI 1.38 to 2.63, P < 0.05). TU also remarkably reduced the scores of Partial Androgen Deficiency of the Aging Males (WMD = -9.49, 95% CI -12.96 to -6.03, P < 0.05) and Aging Males Symptoms rating scale (WMD = -2.76, 95% CI -4.85 to -0.66, P <0.05) but increased the hemoglobin level (SMD = 2.35, 95% CI 0.29 to 4.41, P < 0.05) and packed-cell volume (SMD = 4.35, 95% CI 1.36 to 7.33, P < 0.05). However, no significant changes were shown in aspertate aminotransferase, alanine transaminase, prostate-specific antigen, or prostate volume after TU treatment (P > 0.05).

CONCLUSIONTU could significantly increase the serum testosterone level and improve the clinical symptoms of LOH patients without inducing serious adverse reactions. However, due to the limited number and relatively low quality of the included studies, the above conclusion could be cautiously applied to clinical practice.
