Objective To explore the effect of action research based on group learning in hospice care module for nursing students. Methods 82 students were divided into cooperative learning group (40) and conventional teaching group (42). The cognition and attitude of good death questionnaire was used to evaluate teaching effect before and after teaching of hospice care. After teaching, self-feedback and self-feedback questionnaire were made to evaluate the effect of cooperative learning group. SPSS 17 was used to make comparison of data between groups and within groups, and t test, chi square test or Fisher exact probability 2 were also used . Results There were no difference between two groups of nurses before teaching. The students' cognitive level and attitude in cooperative learning group increased significantly, especially their cognitive level of physiological needs (t=5.398, P=0.001), cognition and attitude of death education in intervention group was higher than control group (t=2.992, P=0.004; t=3.661, P=0.001). Although 95% of the nursing students of the cooperative learning group thought group cooperative studying could improve their interests and cultivated their comprehensive abilities, only 50% could accept this kind of studying methods . Conclusions Action research based on group cooperative studying can improve students' cognitive level and attitude of good death, and it is also good for cultivating their ability of au-tonomous learning, innovation, cooperation, and meanwhile, educational action research is a good way to improve both teaching effect and research ability of teacher staffs, but in practice, students' acceptance of group learning needs to be improved.

OBJECTIVEThis study aimed to investigate the effect of a lactoperoxidase-peroxidase-thiocyanate (LPO-H2O-SCN-) system with different concentrations of iodine (I-) on Streptococcus mutans (S. mutans), particularly on various parameters, including growth, adhesion, glucosyltransferase (GTF) enzyme activity, and insoluble exopolysaccharide synthesis.
METHODSS. mutans ATCC 25175 was used as experimental species. Clonal formation unit (CFU) were counted to investigate the inhibitory effect on bacterial growth. The inhibition rate of bacterial adherence was calculated to analyze the effect on adhesion. Anthrone method was used to determine the content of insoluble exopolysaccharides and the amount of reducing saccharides. GTF activity and enzyme activity were then determined.
RESULTSThe inhibitory ability of the LPO-H2O2-SCN- system with I- on the cariogenicinity of S. mutans was strengthened as I- concentration was increased. At I- concentration > or = 100 micromol x L(-1) the antibacterial effects were significantly increased compared with those of the control group (P < 0.05). At I- concentration > or = 1,000 micromol x L(-1), the antibacterial effects were significantly improved compared with those of the group with SCN-only (P < 0.05). At I- concentration > or = 100 micromol x L(-1), the inhibition rate of bacterial adherence was > 50%; insoluble exopolysaccharide synthesis and GTF enzyme activity were reduced (P < 0.05).
CONCLUSIONThe antibacterial effects of the LPO-H2O2-I- system were enhanced by adding I- to overcome the antagonistic effect of physiological SCN- concentration. LPO-H2O2-SCN- system with different concentrations of I- showed statistically significant inhibitory effects on growth, adhesion, insoluble exopolysaccharide synthesis, and GTF enzyme activity.

BACKGROUND: In patients with obstructive sleep apnea(OSA),the degree of severity of OSA is mostly related to the sleep time spent in the supine position. According to the apnea-hypopnea index(AHI), positional and n onpositional OSA has been distinguished.OBJECTIVE: To compare the clinical characteristics of positional and nonpositional OSA and investigatethe relationship between sleep position and respiratory function of patients with OSA.DESIGN: A comparative clinica] observation based on the OSA patients.SETTING: Center of Sleep Disorders,Nanjing General Hospital of Nanjing Military Area Command of Chinese PLA.PARTICIPANTS: From October 1998 to May 2002,225 patients were examined with overnight polysomnography in the Center of Sleep Disorders,Department of Respiratory Disease, Nanjing General Hospital of Nanjing Command. According to the inclusion criteria of ① AHI≥10 times/hour;② Sleep time in supine and lateral positions≥30 minutes; ③ Over 20years of age; 225 patients were selected from the total of 415 consecutive patients,including 63 with positional and 162 with nonpositional OSA.METHODS: All patients received overnight monitoring with HMS-5500polysomnography system(Respironics Inc USA) in the sleep laboratory. Queries for a detailed case history and physical examination were performed with the pulmonary functions evaluated with body p lethysmography. The clinical data and results of polysomnographic and pulmonary function tests were compared between the two groups of patients and a multiple stepwise regression analysis was employed to evaluate the determinant factors for sleep position dependence of the patients' condition.MAIN OUTCOME MEASURES: Main outcome: Comparisons of the clinical data,polysomnographic result and pulmonary function between the two groups. Secondary outcome: Correlation between classification of OSA and the clinical data.RESULTS: Totally 63 (28%) of the 225 OSA patients were identified as the positional type,who had significantly greater body mass index (BMI)then the nonpositional type patients [(43.46 ± 16.43) kg/m2 vs (23.90 ± 12.36) kg/m2,t =3. 977,P<0.01]. Except for sleeping time in lateral and supine positions, minimal SatO2 and basic SatO2 before the matching for BMI,all the other factors in polysomnograms of the two groups were significant different(P<0.05 or P<0.01). After BMI matching,all the measurements were identical to those recorded for the primary grouping with the exception of nocturnal limb movement frequency,which differed but insignificant between the two groups. The pulmonary function in the two groups was no significant difference(P>0.05) . Multiple stepwise regression analysis indicated that AHI and BMI were the two determinant factors for positional dependence of OSA with a predictive power of 26. 2%. Linear correlation analysis showed correlation of AHI and SatO2 with BMI in the whole group and nonpositional group(P<0.05 or P<0.01),but not in the positional group (P>0.05).CONCLUSION: About one-third of the OSA patients shows sleep position dependence,who may respond favorably to sleep position training. Sufficient patency can be retained in the upper airway of these patients to relieve respiratory obstruction during sleep and improve the respiratory function.

Objective To analyze the clinical, radiological, pathological and microbiological features of invasive pulmonary aspergillosis (IPA) to improve clinical management.Methods Retrospective analysis of 20 pathologically and/or microbiologically confirmed IPA cases in our hospital from January 2005 to August 2008. Results Group A (with underlying diseases) included 13 patients (underlying malignancy in 9 patients, including 5 cases of hematological malignancy, COPD in 2 patients, pulmonary tuberculosis and bronchiectasis in 1 each). Group B (without underlying disease) included 7 patients (2 patients with a long time of fluffy toy contact, another 1 had exposure to moldy rice, and 3 had exposure to polluted water). All these 20 patients had pulmonary invasion revealed by CT imaging. Multiple changes were identified in 16 patients. Bilateral pulmonary infiltrates and/or consolidation were revealed in 7 patients. Multiple nodules were seen in 9 patients. Four patients had solitary lesions, including isolated nodules in 2 patients and segment consolidation in the other 2 patients. Pulmonary cavity without fluid level was found in 8 patients (40.0%). Eighteen cases received antifungal therapy. The overall efficacy rate was 55.6%. The efficacy rate in group A and B was 45.5% and 5/7 respectively. The average time to symptomatic relief was (12.0±2.8) days. The time to lung lesion improvement on CT was (17.4±2.9) days. The time to significant CT improvement was (34.3±9.9) days. The time to the resolution of active lesion was (56.4±6.2) days.Conclusions IPA may occur in immunocompetent patients without underlying disease. Most IPA patients have bilateral multiple pulmonary nodules and cavities on CT. The time to the resolution of active pulmonary lesions is about 6 weeks.

Objective To investigate the biodistribution of intratumoral administerd~(131)Ⅰ-labeled human-mouse chimeric monoclonal antibody (chTNT) in patients with advanced lung carcinoma. Methods Eleven patients enrolled had cytological and histological confirmed diagnoses of either stage Ⅲ b or stage Ⅳ inoperable lung carcinoma. Intratumoral injection was directed by thoracic CT-guided catheter using a multi-holed needle. The dose for each patient was 18.5 - 37 MBq/cm~3 tumor mass. Blood samples were drawn at different time intervals for up to 13 days, and urine samples were collected for up to 11 days after injection for pharmacokinetic studies. In vivo stability was examined by HPLC by analyzing serum and urine, which were found to contain~(131)Ⅰ-chTNT. Whole body images were taken for quantitative organ and tumor biodistribution studies. Results In all 11 patients,~(131)Ⅰ-chTNT was the major component of the radiolabel in serum. Within 96 hours after administration, it was 100% stable. Plasma disappearance curves of ~(131)Ⅰ-chTNT were best fit by a two-exponential model in all patients with T_(1/2kα) of (0. 89±0. 17) h and T_(1/2β) of (86.88 ± 25.97)h. Free Ⅰ was the only metabolite of Ⅰ-chTNT that appeared in urine. A biodistribution study demonstrated excellent localization of the radioactivity in tumors. The accumulated radioactivity in urine at 264 h was (58.37 △Corresponding author E-mail:chen. shaoliang@zs-hospital. sh. cn±17.45) % of the injection dose. There was (51.05±8.41)%ID ,~(131)Ⅰ-chTNT in the tumor at 30 min after injection, and the tumor/lung (T/N) ratio was 63.87 ± 25.71. It remained (3.47 ± 3.27) %ID at 264 h,and the T/N ratio was 9. 61 ± 11.00. Among the main target organs, accumulation of the radiolabeled antibody was mainly found in lungs, liver, heart, kidneys, spleen and thyroid.Conclusions Pharmacokinietics of ~(131)Ⅰ-chTNT follows a two-exponential model. According to its long preservation in tumor tissue, intratumoral injection of~(131)Ⅰ-chTNT is good for tumor therapy.
