Bone marrow stromal cells(MSCs) have been shown to be extremely versatile.Recently,it is demonstrated that MSCs differentiate into neurons.Moreover,under the appropriate conditions,MSCs differentiate into special phynotype of neurons,such as 5-hydroxytryptamine-sensitive neurons,and dopaminergic neurons.The mechanism remains to be elucidated,and an overexpression of neuronal specific genes(such as Sox,Pax,Notch gene) may play an important role,especially RB/PBO gene.However,RB triggers cholinergic differentiation.Extrinsic factor such as concentration of cAMP plays certain role in differentiation.MSCs have also been shown to have certain therapeutic effect on neuronal degeneration disease.These cells have great potential because it is easy to isolate,culture,amplify,and no ethics neither immunologic rejection problem was concerned.

Objective To report the early mortality and associated risk factors after damage control operation (DCO) in patients with severe abdominal trauma.Methods A total of 146 patients hospitalized from January to March in 2015 were retrospectively analyzed.Early death was defined as death occurring within 72 h of first surgery and before the definitive surgery.Based on the death definition, the subjects were divided into death group and survival group.The two groups were compared for gender, age, injury time, injury classification, vital signs, need for cardiopulmonary resuscitation, Glasgow coma score (GCS), injury severity score (ISS), hemoglobin, platelets, prothrombin time (PT), activated partial thromboplastin time (APTT), blood pH, base excess, operative time, and postoperative acute physiology and chronic health evaluation score Ⅱ (APACHE Ⅱ).Logistic regression analysis was applied to examine the predicators of early postoperative mortality.Results There were 118 patients (80.8％) in survival group and 28 patients (19.2％) in death group.Survival and death groups differed significantly with regard to the percent of elderly (6.8％ vs.21.4％), percent of patients with multiple injury (62.7％ vs.85.7％), body temperature [(36.1 ± 0.4) vs.(35.2 ± 0.8) ℃], percent of patients with greater ISS (31.4％ vs.64.3％), PT [(12.1±1.5) vs.(13.9±1.2)s], bloodpH (7.25±0.04vs.7.08±0.11), base excess [(-8.9±2.8) vs.(-10.6±3.3)mmol/L], postoperative APACHE Ⅱ[(12.8 ± 1.8) vs.(17.5 ± 2.0) points] (P ＜ 0.05).Logistic regression analysis identified the age (OR=1.512, 95％ CI 1.112-4.157,P＜0.05), ISS (OR =1.313,95％ CI 1.134-5.442, P ＜ 0.05), APACHE Ⅱ (OR =1.361,95 ％ CI 1.182-5.222, P ＜ 0.05) as the independent risk factors for early mortality.Conclusion The patients underwent DCO for severe abdominal trauma has a high early mortality, which is closely associated with the age, injury severity and postoperative medical status.

Background:Gastric cancer is a common gastrointestinal malignancy. The detection rate of early gastric cancer is still low in China,and some gastric cancer patients visit the hospital due to acute disease,such as gastric perforation. Aims:To investigate the influence of acute disease on long-term prognosis in gastric cancer patients. Methods:A total of 318 patients with gastric cancer from Jan. 2009 to Jan. 2015 at Shaoxing People’s Hospital were enrolled,and were divided into acute disease group and non-acute disease group. Clinicopathological characteristics were analyzed. Patients were followed up,and survival rate was compared between the two groups. Results:Fifty-three(16. 7% )patients had acute disease,and the remaining 265(83. 3% )patients were without acute disease. Compared with non-acute disease group, percentage of TNM Ⅳ stage was significantly increased(P < 0. 05),and percentage of radical surgery was significantly decreased in acute disease group(P < 0. 05). Kaplan-Meier assay showed that survival rate in acute disease group was significantly decreased when compared with non-acute disease group( P < 0. 05). After adjusting the TNM stage and surgical treatment,no significant difference in survival rate was found between the two groups. Conclusions:Gastric cancer patients with acute disease have lower survival rate. Acute disease may be not an independent prognostic factor, higher TNM stage and lower proportion of radical surgery are the main reasons for poor prognosis in gastric cancer patients with acute disease.
