Application of OTD combined with clinical pathway teaching method in the teaching of nursing standardized training in operating room / 中华医学教育探索杂志

Objective:To explore the application of OTD (observation, teaching and discussion) teaching combined with clinical pathway in nursing standardized training in operating room.Methods:A total of 50 nurses who were trained in the Operating Room of The First Affiliated Hospital of Air Force Medical University from August 2017 to June 2020 were selected and divided into control group and study group according to the rotation order, with 25 nurses in each group. Traditional teaching was used in the control group, and OTD teaching combined with clinical pathway was used in the study group. After the rotation training, the teaching effect was evaluated through the assessment of theoretical knowledge and clinical practice comprehensive ability, teaching satisfaction, and the satisfaction scores of participating surgeons and patients. SPSS 22.0 was used for t-test and chi-square test. Results:The results of theoretical assessment, clinical skill assessment and comprehensive ability assessment of operating room of the rotating nurses in the study group were higher than those in the control group, with significant difference ( P < 0.05). The study group was significantly better than the control group in 8 aspects, including learning initiative, stimulating learning interest, problem-solving ability, communication ability, clinical thinking ability, teamwork ability, critical thinking ability and teaching satisfaction ( P<0.05). The satisfaction scores of doctors [(94.06±2.67) vs. (92.17±2.75)] and patients [(94.90±3.22) vs. (91.25±3.10)] in the study group were significantly higher than those in the control group ( P<0.05). Conclusion:OTD teaching combined with clinical pathway can help to improve the theoretical knowledge, clinical practice comprehensive skills and teaching satisfaction of nursing students in operating room, and then improve the teaching quality.

Analysis on willingness to pay for HIV antibody saliva rapid test and related factors / 中华流行病学杂志

<p><b>OBJECTIVE</b>To understand the willingness to pay for HIV antibody saliva rapid test and its influential factors among people seeking counsel and HIV test, STD clinic patients, university students, migrant people, female sex workers (FSWs), men who have sex with men (MSM) and injecting drug users (IDUs).</p><p><b>METHODS</b>An anonymous questionnaire survey was conducted among 511 subjects in the 7 groups selected by different sampling methods, and 509 valid questionnaires were collected.</p><p><b>RESULTS</b>The majority of subjects were males (54.8%) and aged 20-29 years (41.5%). Among the subjects, 60.3% had education level of high school or above, 55.4% were unmarried, 37.3% were unemployed, 73.3% had monthly expenditure <2 000 Yuan RMB, 44.2% had received HIV test, 28.3% knew HIV saliva test, 21.0% were willing to receive HIV saliva test, 2.0% had received HIV saliva test, only 1.0% had bought HIV test kit for self-test, and 84.1% were willing to pay for HIV antibody saliva rapid test. Univariate logistic regression analysis indicated that subject group, age, education level, employment status, monthly expenditure level, HIV test experience and willingness to receive HIV saliva test were correlated statistically with willingness to pay for HIV antibody saliva rapid test. Multivariate logistic regression analysis showed that subject group and monthly expenditure level were statistically correlated with willingness to pay for HIV antibody saliva rapid test.</p><p><b>CONCLUSION</b>The willingness to pay for HIV antibody saliva rapid test and acceptable price of HIV antibody saliva rapid test varied in different areas and populations. Different populations may have different willingness to pay for HIV antibody saliva rapid test;the affordability of the test could influence the willingness to pay for the test.</p>

Relation of 11 C-MET uptake in PET with cell proliferation and angiogenesis in human brain gliomas / 重庆医学

Objective To investigate the relation of 11C-methionine (11C-MET) uptake with cell proliferation and angiogenesis in human brain gliomas .Methods For 30 cases of newly diagnosed glioma patients ,positron emission tomography (PET ) examina-tion with 11C-MET was performed ,and the maximal standardized uptake value (SUVmax) of 11C-MET was measured .Expression of Ki-67 and CD34 antigens was examined by immunohistochemistry method in the same glioma samples ,both Ki-67 labeling index (Ki-67 LI) and microvessel density (MVD) were measured .Results Both 11C-MET SUVmax and Ki-67 LI increased significantly with glioma pathological grade ascending (P=0 .000 ,P=0 .000) ,and which in malignant glioma tissues were significantly higher than those in benign glioma tissues as well (P=0 .000 ,P=0 .000);however ,there were not significant differences in MVD among different grades of gliomas (P=0 .831) as well as between high and low malignant gliomas (P=0 .370) .11 C-MET SUVmax was significantly positively correlated with Ki-67 LI (P= 0 .000) ,however ,there were not significant correlations between 11C-MET SUVmax and MVD (P=0 .154) as well as between Ki-67 LI and MVD (P=0 .842) .Conclusion 11C-MET uptake and cell prolif-eration activity can better reflect the pathological grades and malignant degrees of gliomas .

Expression and significance of calcyclin binding protein in rat brain tissues after traumatic brain injury / 中华创伤杂志

Objective To investigate the expression and significance of calcyclin binding protein (CacyBP)in the brain of rat model of traumatic brain injury(TBI).Methods Sixty 60 male SD rats were divided randomly into normal control group (n=10) and TBI group (n=50).The TBI model was created by using lateral head rotation device and subdivided into 6 h,24 h,72 h,7 d and 14 d group (10 rats per group).The expression and distribution of CacyBP in the rat brain was investigated immunohistochemically.The presence of the brown stained particles was considered aspositiveand lack of the stained particles agnegative. Results CacyBP was mainly distributed in the hippocampus,dentate gyrus and cortical neuron cytoplasm.Compared with the high level expression of CacyBP in the normal control group,the expression of CacyBP was decreased to the lowest in the rat brain at 6 h post TBI (P0.05). Conclusion The lowest level expression of CacyBP after TBI indicates that CacyBP may play an important role in development of brain injury under effect of difierent mechanisms.

Cognitive function changes in response to expression of glucocorticoid recepmr from rat hippocampus after traumatic brain injury / 中华创伤杂志

Objective To explore the effect of glucocorticoid receptor(GR)expression in rat hippocampus on cognitive function after traumatic brain injury(TBI). Methods The TBI model wag established in rats.Then,immunohistochemistry and Western blot were used to detect the GR expression and evaluate its relation with cognitire dysfunction by Morris water maze. Results Expression of hippocampal GR was down-regulated 4-10 days after TBI.Morris water maze test showed significant impairment of the cognitive function in rats. Conclusion There is correlation between expression change of hippocampal GR and cognitive dysfunction.
