A series of isoindoline derivatives were designed, synthesized, and evaluated for their double inhibitory activities. All of them were new compounds, and their structures were confirmed by 1H NMR and HR-MS. Preliminary in vitro pharmacological tests showed that all compounds exhibited 5-HT or NE reuptake inhibition activity. Among the tested compounds, compound I-3 exhibited potent inhibitory activity against 5-HT and NE reuptake in vitro, and exhibited potent antidepressant activity in vivo. These compounds designed can be further optimized for finding more potent 5-HT/NE dual reuptake inhibitors and antidepressant candidates as well.

Objective To investigate the optimal time of extracorporeal membrane oxygenation (ECMO) on repairing Maastricht Ⅱ pig liver with warm ischemia injury for 30 min.Method Thirty-six miniature pigs were randomized to ECMO 2-h group,ECMO 4-h group and ECMO 6-h group,12 pigs per group,6 donors and 6 recipients.Cardiac arrest was induced by administration of 1 g KCl intravenously,followed by cardiopulmonary resuscitation (CPR) for 30 min according to the standard guideline.Cannulas was placed through inferior vena cava and abdominal aorta,then connected to ECMO extracorporeal circulation pipes.Transaminase,circulation flow rate of portal vein and hepatic artery and arterial blood gas were monitored and recorded.The hepatic tissues were cut into sections for pathological observation by HE stain under a light microscope.Apoptosis was detected by TUNEL and apoptotic index was calculated.The liver was stored in cold UW for 2 h after the ECMO circulation,then orthotopic liver transplantation without veno-venous bypass was performed.The levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were measured in the peripheral blood for 5 days after the operation.Result With the increase of the running time of ECMO,transaminase and lactate levels were decreased continuously.Circulation flow rate of portal vein and hepatic artery in ECMO 6-h group was significantly lower than that in the other two groups (P＜0.05).Pathological change in ECMO 4-h group was milder than the rest two groups.Apoptosis index in ECMO 2-h,4-h and 6-h groups was (40.20 ± 7.22)％,(18.60 ± 4.04)％ and (29.25 ± 5.98) ％,respectively.The 5-day suvival rate in ECMO 2-h,4-h and 6-h groups was 83％,100％ and 83％,respectively.The transaminase level in ECMO 4-h group at 5th day after the operation was lower than in ECMO 2-h group and 6-h group (P＜0.05).Conclusion The optimal time of ECMO on repairing Maastricht Ⅱ liver was 4 h.The effect of restoration is not ideal when circulation time is not enough.Liver function and liver cell viability decline beyond 4 h.

Objective To investigate the clinical characteristics of the infections caused by carbapenem-resistant Pseudomonas aeruginosa (CRPA) for better prevention and treatment of CRPA infections. Methods A retrospective study was conducted to compare the features of CRPA infections (n=85) and carbapenem-susceptible P. aeruginosa (CSPA) infections (n=94) treated in Huashan Hospital from January 1, 2013 to December 31, 2013. Results? The?proportion?of?CRPA?infections?was?significantly?higher?than CSPA in Neurosurgery (40.0% versus 16.0%) and Intensive Care Unit (22.4%, 9.6%). Traumatic brain injury (30.6%) and vascular accidents (21.2%) were the main underlying diseases in CRPA patients, which was higher than in CSPA patients (11.7%and?8.5%,?respectively).?CRPA?infection?was?associated?with?significantly?higher?incidence?of?fever,?altered?mental?status,?and?severe hypoproteinemia than CSPA infection. Multiple bacterial infection was found in more CRPA patients (45.9%, 39/85) than in CSPA patients (24.5%, 23/94). Fewer CRPA patients showed positive treatment response (44.7%, 38/85) than CSPA patients (78.7%, 74/94). CRPA was associated with significantly more cases of disease progression (55.3%, 47/85) and more deaths (16.5%, 14/85) than CSPA (21.3% and 1.1%, respectively). Logistic regression analysis indicated that stay in Department of Neurosurgery, prior carbapenem use, peripherally inserted central catheter, nasal feeding, and mechanical ventilation were the risk factors for CRPA infection. Conclusions No specific clinical manifestation is associated with CRPA infection, which poses a therapeutic challenge and results in unfavorable prognosis. Rational use of antibacterial agents and appropriate supporting treatments are essential for control of CRPA in Huashan Hospital.

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.
