Objective To examine the effects of mixed infusion of mesenchymal stem cells(MSCs) and bone marrow cells(BMCs) in the induction of chimerism and islet allograft tolerance.Methods BALB/C mouse was used as the recipient and C57BL/6 mouse was as the donor.BALB/C mice were rendered diabetic via injection of streptozotocin.The islet cells of donor mice were transplanted into the recipient mice under the capsule of kidney.Rat anti-mouse CD154 mAb was intraperitoneally injected to the recipient mice.All of recipient mice(n=25) were then randomly divided into five groups: A group(received nothing),B group(donor MSCs),C group(donor BMCs),D group(donor BMCs and MSCs) and E group(donor BMCs and the third strain-derived MSCs).The chimerism level of donor cells and the survival time of islet grafts were compared among these five groups on 7,30d and 60d after transplantation.Results On 30d and 60d after islet transplantation,the chimerism levels of donor cells in D and E groups,in which the recipient mice received the mixed infusion of MSCs and BMCs,were significantly higher than that in C group,in which the recipient mice received BMCs infusion only,and the survival time of islet graft prolonged from 53.0?16.4d to 77.0?7.7d and 61.0?2.2d,respectively(P

Objective To explore the clinical characteristics and management of kidney transplantation in the older adults.Method Forty older kidney recipients (≥60 years old) and 777 younger (18～59 years old) recipients from June 2009 to December 2012 were retrospectively reviewed to evaluate the clinical characteristics and managements.Result Of 40 older recipients,the comorbidities of diabetes and coronary artery disease in older group were higher than in the younger (25％ vs.4.9％,and 32.50％ vs.11.38％).During the first 6 months,7 older patients died,among which 4 died from severe pneumonia,2 from heart failure and 1 from pulmonary embolism.There were 31 deaths in younger group,among which 21 died from severe pneumonia,4 from heart failure,5 from cerebrovascular accident and 2 from pulmonary embolism.The mortality in the older group was higher than in the younger group (17.5％ vs.4.6％).Six-month and 3-year survival rate in the older recipients was lower than the younger recipients (81.56％ vs.95.35％,and 81.56％ vs.94.5％,respectively).Six-month graft survival rate and 3-year survival rate in the older group were also lower than in the younger group (78.75％ vs.92.02％,and 68.82％ vs.85.40％).At the 1st and 2nd year during follow-up,the serum creatinines in the older group were close to those in the younger group,while lower level was observed 3 years after transplantation in the older patients (89.38 ± 11.34 (mol/ L vs.116.57±48.68 (mol/L).Conclusion The patients with ESRD older than 60 years have more preoperative concomitant diseases and worse health status,which contribute to the complex clinical characteristics.More aggressive indication selection,sufficient pre-operative preparation,wellmatched histocompatibility and high quality of donor kidney are the key factors of successful transplantation.Optimized immunosuppressant therapy,delicate perioperative management,preventve and effective treatment of related complications are necessary to promote the survival of recipients and graft in long term.

Testicular germ cell tumor (TGCT) is a most common testicular malignancy with an increasing incidence, and its pathogenesis and mechanisms are not yet clear. The next generation sequencing has become the main tool to uncover the underlying mechanisms of TGCT. The differential gene expressions, gene mutation, predisposing gene-dominated signaling pathways, and changes of the relevant genes in the sex chromosome are largely involved in the occurrence and development of TGCT. Studies on the genomics of TGCT contribute a lot to identifying the pivotal pathogenic genes and paving a theoretical ground for the early screening and targeted therapy of TGCT. This paper summarizes the advances in the studies of the genomics of TGCT so as to reveal thetmechanisms of the disease at the genetic level.

Objective To study the effect of clinical nursing path with graph and text instructions (GTI) on health education to patients with complex retinal detachment.Methods Toally 76 inpatients with complex retinal detachment were enrolled in the study:38 of them hosptalized from March to August 2015 were put in the control group received routine treatment and the others hosptalized from September 2015 to March 2016 as the experiment group treated with GTI.The clinical outcomes were compared.Result The patients treated with GTI were better in the knowledge of the complex retinal detachment and moreover,they felt significantly more satisfied compared to that of the control group (P＜0.05).Conclusion It is beneficial to use GTI in the patients with complex retinal detachment.GTI is effective for improving their knowledge on the disease,and increasing their satisfaction with the clinical nursing.

Juvenile idiopathic arthritis(JIA)is the most common rheumatology disease in childhood period with poor prognosis.The biological agents are newly developed drugs with features of clear therapeutic targets and fast effects.But its use in JIA is still limited,so this article focuses on the clinical use experience,timming and sideffects of the biological agents on JIA.

ObjectiveTo observe the efficacy and safety of patient-controlled intravenous analgesia (PCIA) with morphine and fentanyl after cardiac surgery.MethodsSeventy patients operated with cardiac surgery were randomly divided into morphine group (group M) and fentanyl group (group F). The beginning efficacy time of analgesia,efficacy of analgesia,patient's evaluation,heart rate,respiratory rate,mean arterial pressure,and incidence of nausea and vomiting were assessed.ResultsThere were no significant differences in efficacy and patient's evaluation between two groups. In group G,the beginning efficacy time of analgesia was significantly shorter than those in group M (P<0.05),and the times of nausea and vomiting were significant less than those in group M (P<0.05).ConclusionPCIA with fentanyl and morphine for postoperative pain relief after cardiac surgery is efficient and safe. Compared with morphine,the beginning efficacy time of fentanyl is significant shorter,and times of nausea and vomiting are little.

BACKGROUND:Some studies indicate that PI3K/Akt signaling pathway is associated with the expression of glucose transporter 4 (GLUT4) and the function of cAMP response element binding protein (CREB) in skeletal muscle. However, it is stil unclear whether PI3K/Akt signaling pathway has the effects on CREB and GLUT4 in skeletal muscle of the rats with high-fat diet and treadmil exercise. OBJECTIVE:To investigate whether PI3K/Akt signaling pathway has the effects on CREB and GLUT4 in gastrocnemius muscle of the rats with high-fat diet and treadmil exercise. METHODS:A total of 70 rats were fed with normal diet for 2 weeks, and randomly divided into common feed group (n=20) and high-fat feed group (n=50). Rats in both groups were respectively fed with common feed and high-fat feed for 8 weeks. The rats in the common feed group were equaly assigned to common feed quiet group and common feed exercise group. 20 rats from the high-fat feed group whose body weight was 1.4 times of common rats were randomly and equaly assigned to obese quiet group and obese exercise group. Rats in the quiet groups did not do exercises. Rats in the exercise groups received adaptive sports for 1 week and medium-intensity treadmil exercise for 8 weeks. RESULTS AND CONCLUSION:(1) Impairments of PI3K/Akt signaling pathway appeared in obese rats, however, the quantity of GLUT4 expression did not change obviously in gastrocnemius muscles of obese rats. The reasons for the decrease of the nuclear protein CREB level of gastrocnemius muscles of obese rats might be related to the decrease of pAkt-Ser473 level. (2) The increase of the quantity of GLUT4 expression was accompanied by significantly up-regulated pAkt-Ser473 level by exercise intervention in gastrocnemius muscles of obese rats. Exercise intervention significantly increased the expression of nuclear protein CREB in gastrocnemius muscles of chow-fed rats and obese rats, which was consistent with the changes of pAkt-Ser473. These findings suggest that pAkt-Ser473 can play an important role in the effects of high-fat diet and exercise intervention on GLUT4 and CREB protein expression in gastrocnemius muscles of obese rats.
