Objective The study discussed the underlying mechanism of the impact of perceived social support on individual learning behavior from the perspective of the psychosocial impact theory .Methods 224 students majored in public management were involved ,and the dada was collected by questionnaires ,then the conceptual model was tested by moderate effect sequence of statistical analysis .Results The findings were as follows :Firstly ,perceived social support had a significant effect on individual learning behavior (β=0 .332 ,P<0 .01) .Secondly ,the relationship between perceived social support and individual learning behavior was moderated by self efficacy (β= -0 .216 ,P<0 .01) .Conclusion Perceived social support and self efficacy have moderate effect on individual learning behavior .

To attach importance to practice teaching in clinical microbiological analysis,the overall planning,research-on-research and systematic training must be carried out.

Objective To make an investigation for autoantibodies detection in China. Method Forty-eight hospitals were included by mail or Email. The items of QC include ANA, anti-ENA antibody, anti-dsDNA antibody, anti-mitochondria antibody and anti-smooth muscle antibody. The distribution of samples and analysis of the testing results was double-blinded. Result The correct rate of ANA, anti-ENA antibody, anti-dsDNA antibody, anti-mitochondria antibody and anti-smooth muscle antibody were 47%, 70%, 46%, 95%and 40% respectively. Conclusion The overall results are not optimistic. The quality of detecting kits is not all good, neither level of technicians. This condition should be changed by selecting better methods and improving understanding.

Objective To analyze the outcome of patients with acute obstruction of left colorectal cancer treated by modified antegrade colonic lavage with primary tumor resection and anastomosis.Methods From April 2002 to April 2007,112 patients with acute obstruction of left colorectal cancer underwent surgery.During the operation the left colon was exteriorized and placed into a sterilized plastic bag to protect the surgical field from contamination,then a catheter was inserted via the appendix,and after antegrade colonic lavage,primary resection and anastomosis was performed.Results Tumor resection and primary anastomosis was successfully done in the 112 cases.Postoperatively,1 case had anastomotic leak which healed after reoperation with proximal colostomy,and one patient died.Conclusions Modified antegrade colonic lavage is a simple procedure,the bowel can be rapidly decompressed with essentially no contamination,and has a high level of bowel cleansing.It is possible to safely perform primary resection and anastomosis for left colon cancer after the modified antegrade lavage.

Objective To discuss the method to increase the success rate of stomach tube insertion for patients with indwelling nasotracheal tube in order to shorten the time of insertion operation and reduce the discomfort of patients.Methods Seventy patients with nasotracheal tube were randomly divided into the observation group(38 cases)and the control group(32 cases).When the operator for the observation group inserted stomach tube to 18～22 centimeters deep,the nurse pumped the gas out from the tracheal catheter aerocyst.After the stomach tube reached stomach the tracheal catheter aerocyst was aerified again.The control group did not release the gas from tracheal catheter aerocyst when inserting the stomach tube.The first intubation success rate and time needed for intubation were compared between the two groups.Results The first intubation success rate of the observation group was higher than that of the control group(P＜0.05).While the time needed for intubation was shorter than that of the control group(P＜0.01).Conclusions Method used by the observation group not only increased the first intubation success rate,but also shortened time needed for intubation.This method can alleviated pain of patients and worth applying widely in clinic.

Objective To compare the postoperative recovery of vaginal and abdominal hysterectomies of non-prolapsed uterus ,in order to offer the advantages, surgical indications and contraindieations ,surgical characteristic and diflieuhy of transvaginal hysterectomies of non-prolapsed uterus. Methods To retrospectively analyze 480 cases transvaginal hysterectomies (TVH) and 440 cases transabdominal hysterectomies (TAH) with similar indications in the corresponding period, and compare the operation duration ,blood lost during the procedure, postoperative analgesic, morbidity, recovery time of the function of intestine, activity time of getting up and hospitalization between those surgi-ca] techniques. Results There were no intraoperation and postoperative complications in group TVH. In group TAH: more blood was lost(P <0.01) ,the function of intestine recovered more slowly(P <0.01) ,more analgesic needed, more morbidity noted (P < 0.01), activity time of getting up is much longer(P < 0.01). The hospital stay after opera-tion was much shorter in group TVH(P <0.01). No statistical difference was found between the two groups in terms of the duration(P 0.05). Conclusion TVH is minimal invasive surgery that include small trauma,reduced pain, no abdomen scar and quick recovery. So the patients are happy to accept it.

Objective To investigate the relationship between the expression of IFN-γ, IL-2 and TNF-αand pathological damage of lung tissue, and to provide reference values for protection and treatment of pulmonary tuberculosis. Methods BALB/c mice models of pulmonary tuberculosis were established by infection with Mycobacterium tuberculosis H37Rv through the caudal vein. At 0 (not infected),2,4,6W and 8W after infection, the bacterial loads in the lung were performed and the pathological damage of the lung was evaluated, respectively. At the same time, the expression of IFN-γ,IL-2 and TNF-α-positive cells in the lung tissues was detected by immunohistochemistry. Results Two weeks after infection, the expression of IFN-γ, IL-2 and TNF-αpositive cells was obviously increased compared with those at 0 week. The proportion of IFN-γ-positive cells were obviously decreased at 6 weeks (9.25%) to 8 weeks (5.67%) after infection with Mycobacterium tuberculosis H37Rv. At the same stage, there is a limited decrease tendency of TNF-α and IL-2 expression compared with those at 4 weeks after infection, and there was no significant difference compared with those at 2W or 4W after infection. At 8 weeks after infection, the bacterial loads (8.43) in the lung and the scores(17) of pathological damage were significantly increased compared with those at 6 weeks after infection. Conclusion The high expression of IFN-γ, IL-2 and TNF-αprotect lung tissues against MTB infection at the early stage. The decrease of IFN-γexpression is responsible for serious damage of the lung tissues in the persistent infection.

Objective To investigate the CD44v6 and heparanase in non-small cell lung cancer (NSCLC ) and adjacent normal lung tissues ,and to study the correlation of these two molecular in non-small cell lung cancer invasion and metastasis .Methods The expressing of CD44v6 and heparanase in 117 patients with non-small cell lung cancer tissues and 62 adjacent normal lung tissue was detected by immunohistochemical staining .Results The expression of CD44v6 in NSCLC was 54 .7% (64/117) ,which was sig-nificantly higher than in adjacent tissues of 4 .8% (3/62)(P<0 .05);the expression of heparanase in NSCLC was 86 .3% (101/117) ,which was significantly higher than the normal adjacent tissues 17 .7% (11/62)(P<0 .01);CD44v6 expression in NSCLC ex-pression was positive correlated with heparanase .Conclusion CD44v6 and heparanase are associated with the invasion and metasta-sis of NSCLC ,combined detection of the expression of the two molecular maybe has a certain reference value in determine the prog-nosis of NSCLC .

Objective To study the cognitive behaviors of ICU nurses about cluster intervention strategies of central venous catheter blood infection.Methods Two hundred and two ICU nurses were involved in the survey using self-designed questionnaire.Results The scores on knowledge of ICU nurses with cluster intervention strategies was(31.9±2.8)and the score on the cognitive behaviors was(26.9±2.6). Conclusions The ICU nurses’knowledge on cluster intervention strategies is at a general level and their behaviors are at the status ofseldomorsometimes.Therefore,improvement of manipulation flowsheet,control of routes for bacterial infections and enhancement of knowledge learning are critical for the improvement of cognitive behaviors of ICU nurses with cluster intervention strategies.
