Objective:To investigate the regulation mechanisms of the bone marrow mesenchymal stem cells on lymphocyte pro -liferation of type I diabetic rats .Methods:The rat bone marrow mesenchymal stem cells were isolated , cultured and identified and the effect on lymphocyte proliferation of type Ⅰdiabetic rat was observed by MTT assay , and analyze the CD 4 +CD25 +regulatory T cell ra-tio, cell cycle and apoptosis of type I diabetes rat by flow cytometric .Results:B and C groups was significantly lower than the absor-bance values of group A,the differences between the data were statistically significant (P<0.05), C group was significantly lower than group B absorbance values, the difference was significant (P<0.05);the CD4 +CD25 +regulatory T cells of B and C groups were sig-nificantly higher than group A, the differences of the data were statistically significant (P<0.05), the CD4 +CD25 +regulatory T cell ratio of C group significantly higher than that group B , the differences were statistically significant (P<0.05);the apoptosis levels of B and C groups were significantly higher than group A , the differences were statistically significant (P<0.05), the apoptosis levels of C group were significantly higher in group B , the differences were statistically significant (P<0.05).Conclusion:Bone marrow mesen-chymal stem cells can significantly inhibit lymphocyte proliferation of type Ⅰdiabetic rats, and it may regulate CD4 +CD25 +regulatory T cells, promote apoptosis, thereby affecting the immune function of T lymphocytes , and play its rejection.

Objective To observre the change of plasma arginine vasopressin(AVP)in plasma and relationship of AVP with brain edema after traumatic brain injury(TBI).Methods The rat models of mild and severe degree local cerebral cortex injury were caused by free dropping.Radioimmunoassay was used to measure serial concentration of AVP in plasma in 45 rats with acute brain injuries at the 24th,48th,72th hour and the 5th day after brain injury.The content of injury brain water was measured by drying-wetting way.Results AVP levels had positive correlation with the severity of brain edema.The severer brain injury resulted in higher AVP level and longer persistent time of peak brain edema(P<0.05).Conclusion AVP level is closely associated with edema after TBI.AVP may play a vital role in pathogenesis of brain edema.

Objective To investigate the relationship between helicobacter pylor (Hp) and primary carcinoma of the gallbladder (PCG), providing a theoretical basis for the treatment of PCG.Methods Mucosa and bile of gallbladder samples were collected from 18 patients with PCG (PCG group), 40 patients with chronic cholecystitis or cholelithiasis (CC group), and 20 patients with no PCG and CC (control group). 16S rDNA-based polymerase chain reaction (PCR) followed by DNA sequence analysis of the obtained PCR fragments was performed. A developed search for Hp was also carried out by PCR. Five genes specific for Hp were amplified. Results In the PCG group, 81% samples of mucosa and bile were positive for Helicobacter-specific 16S rRNA gene. The positive rate in PCG group was significantly higher than those of the CC group (50%) and the control group (20%).Of the 16S rDNA sequence of Helicobacter pylori positive samples of mucosa and bile, 52% of samples were positive in cagA, 86% were positive in 26 KDa, 48% were positive in ureA separately. The vacA and rps4 genes were never detected in any of the samples of mucosa and bile. At least one gene was positive in 93% of samples of musca and bile. The sequencing showed more than 99% homology of Helicobacter 16S rRNA in PCG and Hp groups. Conclusion A higher infection rate is present in bile and gallbladder mucosa from patients with PCG. Hp in the biliary system may be one of the risk factors for occurrence of PCG.

Pender′s health promotion model explains the factors influencing health behaviors, which provides a framework for nursing practice and research. Functional exercise compliance in postoperative patients with breast cancer was in a low level, this article reviewed factors influencing functional exercise among breast cancer survivors through three aspects based on health promotion model and made some suggestions on nursing intervention, to promote the rehabilitation of this population.

Objective To evaluate the complication rate of secondary surgery in patients with benign thyroid disease. Methods From June 1992 to June 2003, 65 patients underwent reoperation. Operative procedures. pathology and complications were reviewed. Results The first surgery was unilateral in 27 cases (41.5%), bilateral in 38 (58.5%). Reoperation identified carcinoma in 8 cases with complications developed in 8 cases and left over permanent in 1 case (1.5%). Conclusion The complication rate of second operation is higher than that of first thyroid surgery, but still acceptable.

Objective To assess the correlation between pre-operative N-terminal-pro-brain natriuretic levels and early survival rate among heart transplantion (HT) recipients in a single Chinese center.Methods According to the pre-operative NT-proBNP level of 284 HT recipients,the recipients were divided into two distinctive groups,≤5000 nmol/L group (237 cases) and >5000 nmol/L group (47 cases).The baseline characteristics and mortality for recipients with different primary cardiac diseases and on extracorporeal membrane oxygenation (ECMO) support were compared.Kaplan Meier method was used to calculate the 1-year survival rate of the two groups.Results The pre-operative NT-proBNP >5000 nmol/L group had an average pulmonary capillary wedge pressure of (25.1 ± 7.4)mmHg,noticeably higher than in ≤5000 nmol/L group [(21.4 ± 9.2) mmHg,P<0.05].At the same time,the cardiac index (CI) in >5000 nmol/L group was (1.8 ± 0.5) L·min-1·m-2,significantly lower than in ≤5000 nmol/L group [(2.1 ± 0.6) L·min-1 ·m-2,P<0.05].14.9%(7/47) of recipients in >5000 nmol/L group used ECMO support,and the corresponding ECMO-related morbidity was 71.4% (5/7) and 1-year survival rate was 91.3%.6.8% (16/237) of recipients in ≤ 5000 nmol/L group used ECMO support and the corresponding ECMO-related morbidity was 12.5% (2/16) and 1-year overall survival rate was 96.9%.There was statistically significant difference in the ECMO usage,ECMO-related mortality rate and 1-year survival rate between the two groups (P<0.05).Conclusion Recipients with pre-operative NT-proBNP >5000nmol/L have higher peri-operative ECMO-related morbidity and 1-year death rate.So determination of pre-operative NT-proBNP level may be beneficial to the timing of cardiac transplantation.
