Objective To explore the effects of cognitive behavioral intervention in psychological nursing of young female patients with facial burn.Methods 64 cases of young women patients with facial bum were selected as the research object,and randomly divided into the observation group and the control group,with 32 cases in each group.The observation group was given the cognitive behavioral intervention and the control group was done by conventional nursing methods.The anxiety and depression scores between the two groups before and after the intervention were compared.Results After injury,the anxiety and depression scores of both the observation group and the control group were higher than those of the domestic norm; the anxiety and depression scores between two groups showed no statistic significance before intervention,and after intervention,the anxiety and depression scores between two groups had significant difference,scores of the observation group were lower than those of the control group.Conclusions Cognitive behavioral intervention can reduce anxiety and depression of young female patients with facial burn.It is a kind of effective psychological nursing method,and worthy of clinical promotion.

Objective To detect circulating antigen (Cag) for diagnosing neurocysticercosis. Method ELISA was performed with monoclonal antibody 4B6 against the cyst fluid antigen of Cyticercus cellulosae for detecting Cag in serum and/or cerebrospinal fluid (CSF) of patients with neurocysticercosis or with other diseases. Results In the group of 82 cases of neurocysticercosis, the positive rate of serum Cag was 79.2% (65/82) and the positive rate of CSF Cag was 100% (26/26). After chemotherapy for 20 cases with positive serum Cag, the titer of serum Cag in 17 cases dropped to zero(85% ). Cag could not be detected in specimens from patients with other diseases. Conclusion These results indicate that the determination of Cag, especially of the CSF Cag, is useful for the diagnosis of neurocysticercosis and the drop in serum Cag is a good parameter for the evaluation of the effectiveness of chemotherapy.

Objective: To evaluate the surgView-RFT electromagnetic navigation system in radiofrequency thermocoagulation(RFT). Methods: 6 foramen ovales of 3 cadavers were punctured by 3 beginners. Every one tried 5 times by free-hand and 5 times by SurgView-RFT electromagnetic navigation-guidance. After each puncture, CT scans were used as golden standard to measure the distance between the tip of needle and the anterior margin of the foramen ovale. T test and variance of SAS 6.12 statistical software was used to do the statistic analysis. Results: The punctures by free-hand failed, and the distances between the tip of needle and the anterior margin of the foramen ovale were 8-10.6 mm. The punctures by navigation guidance were successful, and the distances between the tip of needle and the anterior margin of the foramen ovale were 2.68-3.54 mm. The error of navigation system was 0.59 mm which was verified by CT scan. There was significant difference between free-hand puncture and navigation-guided puncture. Conclusion: The surgView-RFT electromagnetic navigation system is characteristic with high performance, high accuracy and minimal invasion, while it is applied in training or clinical using.

Objective To investigate whether macrophage-activating lipopeptide-2 ( MALP-2) in-duces the expression of hemoxygenase-1 ( HO-1 ) in THP-1 cells and to further elucidate its possible regulatory mechanism for a better understanding of protective response upon mycoplasma infection .Methods THP-1 cells were cultured in vitro and stimulated by MALP-2 at different concentrations for 12 h.THP-1 cells were incubated with TLR 2 or TLR6 neutralizing antibodies , or transfected with their dominant negative plasmids to evaluate the effects of TLR 2 and TLR6 on HO-1 expression .Phosphorylation of Akt was detected by Western blot.PI3K inhibitor LY294002 was used to investigate the role of PI3K in HO-1 expression.Im-munofluorescence and electrophoretic mobility shift assay ( EMSA ) were performed to observe the nuclear translocation and DNA-binding activity of nuclear factor Nrf 2.Small interfering RNA ( siRNA) was used to silence the genes encoding Nrf2 and HO-1.Cobalt protoporphyrin (CoPP), an inducer of HO-1, was used to treat THP-1 cells.The expression of HO-1 was detected by Western blot .The secretion of TNF-αand IL-1βby THP-1 cells were measured by ELISA .Results MALP-2 induced the expression of HO-1 in THP-1 cells.However, the expression of HO-1 was inhibited by TLR2 and TLR6 neutralizing antibodies and expres-sion of their dominant negative plasmids .Moreover, PI3K pathway was activated by MALP-2, and with the use of PI3K inhibitor, the expression of HO-1 was decreased.The translocation of Nrf2 to the nucleus and itsDNA-binding activity were enhanced by MALP-2, but were inhibited by the treatment of PI3K inhibitor.Theexpression of HO-1 was significantly down-regulated upon the interference of Nrf2 gene expression withsiRNA.Silenced expression of HO-1 increased the level of TNF-αand IL-1β, while CoPP treatment decreasedthe secretion of MALP-2-induced cytokines.Conclusion MALP-2 might induce the expression ofHO-1 in THP-1 cells through TLR2,6/PI3K/Nrf2 pathways.The expression of HO-1 could negatively regulatethe hyper-secretion of cytokines.

Objective To explore the application effects of transitional care on the prevention of scar hyperplasia after burn.Methods A total of 110 burn patients, who were treated in our hospital from February 2015 to February 2016, were divided into two groups according to the order of admission, 55 cases respectively. Patients in the control group were given regular discharge guidance and follow-up, while patients in the experimental group were given additional transitional care. The treatment compliance and the score of Vancouver Scale were compared between the two groups at six months after discharge.Results At six months post discharge, the proportions of patients who were prescribed medication, adhered to stress treatment, rehabilitation exercise, and on-time referral in the experimental group were 80.39%, 74.51%, 76.47% and 84.31% respectively, all of which were significantly higher than those in the control group (χ2=9.607, 7.985, 10.471, 11.411,P<0.05). At six months after discharge, the Vancouver scar scores were (6.03±1.98) in the experimental group and (7.56±2.03) in the control group, with statistically significant differences between the two groups (t=-3.815,P<0.05).Conclusions Transitional care can improve the treatment compliance of burn patients and reduce the degree of scar hyperplasia.

ObjectiveTo investigate the prevalence,antibiotic characteristics as well as molecular background of community-associated methicillin-sensitive Staphylococcus aureus (CA-MRSA) from patients with skin and sofi tissue infections from 4 different hospitals in Beijing.MethodsFive hundred and one patients were enrolled from 4 hospitals prospectively.Patients with skin and soft tissue infections and no risk factors for healthcare-associated acquisition were included.Sample from the infection sites were collected for culture.Case report form was filled out for each patient.Antibiotic susceptibility test and molecular analysis was performed for each Staphylococcus aureus isolate.ResultsTotally 164 Staphylococcus aureus isolates were cultured from the patients with skin and soft tissue infections.Of them 5 isolates were CA-MRSA.These 5 CA-MRSA isolates harbored SCCmec Ⅰ, SCCmec Ⅲ, SCCmec Ⅳ,SCCmec Ⅴ and untypable,respectively.CA-MRSA was highly resistant to β-lactamase,levofloxacin,erythromycin and clindamycin,but susceptible to vancomycin,teicoplanin,linezolid,daptomycin,and trimethoprim/sulfamethoxazole.Prevalence of PVL in community-associated methicillin sensitive Staphylococcus aureus(CA-MSSA) and CA-MRSA were 41.9％ and 2/5.Other toxins expressed similarly between them.Combined with multilocus sequence typing (MLST) and spa typing,the major clones of CA-MSSA were ST398-t034,ST7-t796,ST398-t571,ST1t127,and ST188-t189,while in CA-MRSA were ST239-t037-SCCmec Ⅰ,ST239-t632-SCCmecⅢ,ST59-t437-SCCmecV,ST8-t008-SCCmecⅣ,and ST6-t701-NT.ConclusionsThe low prevalence of CA-MRSA in Beijing and complexity of the genetic background in CA-MRSA were observed.Clone spread is not found among CA-MRSAisolates.CA-MRSAexhibithigher resistancecomparedwithmethicillinsensitive Staphylococcus aureus (MSSA).Rational drug use scheme is called in the clinical practice to prevent development of high level resistance.

Objective To explore the clinical feature,treatment and prognosis of incidental prostate cancer(IPC) after transurethral resection of the prostate (TURP) for benign prostatic hyperplasia (BPH).Methods From January 2009 to April 2017,24 cases undergoing TURP for benign prostatic hyperplasia and being diagnosed with prostate cancer(T1a-T1b) was retrospectivey analysed,who aged from 62 to 84 years (mean 71.8 years).Digital rectal examination (DRE) showed prostate medium texture,smooth surface,and no nodules.Ultrasound presented no low echo nodules in the prostate.Prostate volumes were 19.2-93.4 ml,with median of 40.1 ml.PSA were 1.81-9.11 ng/ml,with median of 4.12 ng/ml.The patients with PSA between 6-10 ng/ml accepted prostate biopsy,and pathological results were negative.Results The The pathology of TURP specimens in 24 cases were diagnosed prostate cancer (21 cases of T1a,3 cases of T1b).According to the new WHO/ISUP classification group,there were 18 cases of hierarchical group 1,3 cases of hierarchical group 2,1 case of hierarchical group 3,2 cases in hierarchical group 4.All patients were treated with hormonal therapy,and 7 cases (5 cases of hierarchical group 1,and 2 cases of hierarchical group 2) underwent laparoscopic radical prostatectomy (LRP) after 3 months of hormonal therapy.The specimens of prostatectomy were examined by whole-mount serial,showing 3 cases of prostate cancer (T1a) with negative margin,and 4 cases of benign prostate cells.They were followed up for 5-82 months with median of 43.5 months.No biological progression or tumor progression was found,and,1 case died of colon cancer after 26 months of follow-up.The patients' age and Gleason score of stage T1b were higher than that of stage T1a.Prostate volume and preoperative PSA had no statistically significant difference between the two stages.Conclusions The patients' age and Gleason score of stage T1b were higher than that of stage T1b.The proportion of residual tumor following TURP was high.The prognosis of incidental prostate cancer was good by hormonal therapy or radical prostatectomy.

ObjectiveTo evaluate the efficacy of three screening questionnaires for COPD in the community residents of Songjiang District， Shanghai， and to provide a basis for selecting COPD screening questionnaire and process that are more suitable. MethodsCommunity residents aged 40 years or over were randomly selected from the Shanghai Suburban Adult Cohort and Biobank for the study with screening questionnaires and spirometry. Questionnaires included the COPD screening questionnaire （COPD-SQ）， the COPD population screener （COPD-PS） and the revised COPD diagnostic questionnaire （revised-CDQ）. Evaluation of the efficacy of these questionnaires was based on the area under the receiver operating characteristic curve （AUC） of the subjects. DeLong test was used to compare the accuracy of different questionnaires； Z test was used to compare the accuracy of different cut-off values for the same questionnaire. ResultsAmong 3 184 community residents， a total of 259 （8.1%） COPD patients were screened by spirometry. AUC values of these 3 screening questionnaires were >0.7 indicating that they were reliable COPD screening tools. The sensitivity and specificity of the questionnaires at the recommended cut-off values were COPD-SQ （63.7% and 72.2%）， COPD-PS （12.0% and 96.1%）， and revised CDQ （78.8% and 52.7%）， with the COPD-SQ having the highest screening accuracy （AUC=0.754）. The optimal and recommended cut-off values for the three questionnaires differed in this population， but the difference in accuracy was statistically significant only for COPD-PS. The optimal cut-off values for the three questionnaires differed between male and female， and the sensitivity and accuracy of COPD-SQ and COPD-PS improved when lower cut-off values were used for women. The AUC was greater when two questionnaires were utilized simultaneously for screening， but the differences were not statistically significant. ConclusionThe COPD-SQ is recommended for primary COPD screening； a lower cut-off value for women should be considered. The COPD screening questionnaire needs to be further improved for the early diagnosis and treatment of COPD patients.
