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 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 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.

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 understand the expiration date of alcohol-based hand disinfectant after it is opened for use,and provide reference for rational clinical application of alcohol-based hand disinfectant.Methods 20 bottles of the same brand alcohol-based hand disinfectant which opened at the same time by the clinical departments were selected as the study object,hand hygiene compliance in theses departments ranked fourth from the end in the hospital,specimens were taken on the first day after opening,and repeated every 10 days until the disinfectant was used up.Hand specimens were also taken after disinfected by disinfectant.Qualified condition of disinfectant and hand specimens was detected.Results A total of 98 disinfectant specimens were collected,by naked eye observation,20 bottles of alcohol-based hand disinfectant were free of discoloration,precipitation,and suspended matter during the whole study period.The qualified detection rates of alcohol-based hand disinfectant within 60 days after opening were all 100%.44 hand specimens were taken and detected after disinfection,3 of which were unqualified(all were disinfected by alcohol-based hand disinfectant 50 days after opening),then detected again after disinfected by the same batch of disinfectant,all were qualified,which suggested that unqualified detection result of hand specimens was not due to disinfectant.Conclusion Alcohol-based hand disinfectant still has a good bactericidal effect on the sixth day after opening.
