Objective To compare the biological characteristics of adipose-derived mesenchymal stem cells (ADAS) and bone marrow derived mesenchymal stem cells (BMSCs).Methods The adipose and bone marrow-derived sources of mesenchymal stem cells were separated,and their phenotype,cell doubling time and the secretion of factors were compared.They were also used to detect T-cell cycle,activation,and proliferation inhibition.Results BMSCs and ADAS were similar on the cell phenotype and the differences only existed in the expression of only CD106.For the proliferation rate,ADAS grew faster than BMSCs (doubling time 28 h vs.39 h,P＜0.05); ADAS and BMSCs also had the same ability to inhibit T cell proliferation,and dose-dependent effects existed in mitogen-stimulated Tcell proliferation and MLR: there was a strong inhibitory effect in 1:2,but this effect disappeared at 1: 100.Both ADAS and BMSCs could arrest most T cells in the G0/G1 phase,but the role of ADAS was weaker than that of the BMSCs.ADAS could not inhibit apoptosis of T cells.ADAS and BMSCs played the same roles in inhibiting the differentiation of TH0 to TH1 or TH2: mainly inhibiting differentiation of TH 0 to TH1 cells (IL-2-and IFN-γ-producing cells),but having no significant effect on TH2 cells (IL-4-and IL 10-producing cells).Conclusion ADAS and BMSC have a similar role in immune regulation.In the same volume,fat tissue has the number of more than 10 times of stem cell precursor cells than that of bone marrow,so adipose tissue is a more promising stem cells transplant source.

Objective Using Nutrition Risk Screening (NRS 2002),to assess the nutritional risk of inpatients with digestive diseases and evaluate its clinical significance.Methods The information of 274 patients med the inclusion criteria were collected in our department from August to October 2011.Nutrition status was assessed according to NRS 2002 by trained nurses.Results The prevalence of nutritional risk was 22.99 ％ (63/274).The rate of nutritional risk of the elderly inpatients (≥ 65y) with digestive diseases was significant higher the younger ones (＜ 65y)(32.95％ vs 18.28％,P ＜ 0.05).74.6％ inpatients with nutritional risk and 52.13％ with no risks were given enteral or parenteral nutritional support during the hospitalized period.Conclusion There was higher nutritional risk rate in inpatients with digestive diseases,especially the elderly ones.For deferent patients,the nutritional support should be on the basis of patient' s nutritional state.

BACKGROUND: At present, more and more scholars pay attention to the influence of spine and pelvis sagittal balance on the quality of life of patients. Postoperative changes in spine imaging parameters fol owing corrective osteotomy for lumbar degenerative kyphosis have not been reported. OBJECTIVE: To evaluate postoperative changes in sagittal balance fol owing corrective osteotomy for lumbar degenerative kyphosis. METHODS: We retrospectively analyzed 35 consecutive lumbar degenerative kyphosis patients treated with posterior osteotomy fixation in the First Affiliated Hospital of Xinjiang Medical University from February 2012 to December 2014. Imaging parameters were measured before fixation, immediately after fixation and during final fol ow-up. RESULTS AND CONCLUSION: (1) There were significant differences between preoperative and postoperative parameters except for pelvic incidence angle (P < 0.05). (2) There were significant differences between postoperative and last fol ow-up parameters except for Cobb angle, pelvic incidence angle, thoracic kyphosis angle and the thoracolumbar kyphosis (P < 0.05). (3) Pelvic tilt angle was negatively correlated with lumbar lordosis after fixation (r=-0.610, P < 0.001). Thoracic kyphosis was positively correlated with lumbar lordosis (r=0.598, P < 0.001). (4) Results suggested that lumbar sagittal contour can be significantly improved by corrective osteotomy for lumbar degenerative kyphosis. Simultaneously, reciprocal changes in the adjacent areas such as thoracic spine and pelvis occur to adapt to the new sagittal balance.

Objective To explore the clinical features and surgical management of aged patients with acute cholecystitis,and try to command the opportunity and procedure of laparoseopic cholecystectomy(LC)better.Meth- ods Clinical data of 52 aged cases with acute cholecystits undergone LC were analyzed retrospectively.Results All of the patients(within 48h of the acute attack)were successfully recovered without serious operative complications. Conclusion Aged acute cholecystitis progressed rapidly and its operative difficulty and risk were higher;only if more attention was paid to perioperative managements and operative time and technical skill were mastered,early LC for the patients was safe and feasible.Therefore.it should be recommended in the great majority of cases except the des- perate patients whose general condition was too poor to operate.

By participating in the research practice of basic medicine,the innovative consciousness,the scientific thinking and researching ability of seven-year program medical students can be improved. Meanwhile,the generalization of Open Experimental Teaching and further development of self-design experiment also improve the innovation and research ability of medical students,which can serve as a new approach to the quality education of higher medical talents.

Objective To evaluate the feasibility, therapeutic effects and normal tissue complications of three-dimensional conformal radiotherapy (3DCRT) for loco-regionally recurrent esophageal cancer after initial radiotherapy. Methods Between March 2001 and May 2007, 42 patients with loco-reigonal recurrent esophageal cancer after initial radiotherapy were treated with 3DCRT, including 27 male and 15 female with a median age of 67.5 years. Radiotherapy was delivered at 1.8 -2.0 Gy per fraction, 5 fractions per week, with a median total dose of 54 Gy. Treatment outcomes and normal tissue complications were assessed with WHO and RTOG/EORTC criteria. Results By December 31,2008, the follow-up rate was 100%. Twenty patients had follow-up time of 1 year and the remaining 22 had 2 years. The clinical symptom relief rate was 60%, and the response rate was 90.5% with a complete remission rate of 17% and partial remission rate of 74%. The overall 1- and 2-year survival (OS) rates were 60% and 24%. Grade 2 and grade 3 acute radiation esophagitis developed in 31% and 5% of the patients, respectively. Grade 2 and grade 3 acute radiation pneumonitis developed in 19% and 2% , respectively. Grade 2 and grade 3 acute radiation hematology toxicities developed in 5% and 2%, respectively. Conclusions For patients with loco-regional recurrences of esophageal cancer after initial radiotherapy, 3DCRT is feasible, with a good clinical symptom relief rate and immediate tumor response. However,the complication rate was high and the clinical indications should be strictly controlled.

Objective To determine the frequency of polymorphism at exon 26 (C3435T) of muhidrug resistance 1 gene (MDR1) in epileptic patients in the southern Chinese and to study the association of this polymorphism with pharmacoresistance.Methods DNA samples were obtained from 134 patients,of whom 72 were resistant to antiepileptic drug treatment and 62 were responsive to the treatment. Genotypes of the C3435T polymorphism were determined by polymerase chain reaction (PCR) followed by restriction digestion and gel electrophoresis.Genotype and allele frequencies in the drug resistant group were compared to those in the response group by Chi-square analysis.Results Of all 134 patients,33 (24.6%) had CC genotype,72 (53.7%) had CT genotype,and 29 (21.6%) had TT genotype.The frequency of CC genotype was significantly higher in the pharmaeoresistance group (33.3%) than that in the responsive group (14.5%,P=0.012).The frequency of the C allele was also significantly higher in the pharmacoresistance group (57.6%) than that in the responsive group (44.4%,P=0.03).When patients were divided by types of seizure into three groups:generalized seizure group,partial seizure group,and undefined seizure group,the CC genotype and C allele were associated with pharmacoresistance in the partial seizure group.Conclusions In the southern Chinese,the CC genotype and C allele are associated with resistance to the antiepileptic treatment.This finding needs to be verified in studies with larger sample size.
