Objective To analyze influencing factors of small airway dysfunction(SAD)in children with bronchial asthma,and construct a risk prediction model for SAD.Methods A total of 221 bronchial asthma children with normal pulmonary ventilation function were retrospectively selected as the modeling group.According to the presence of SAD,children were divided into the SAD group(43 cases)and the non-SAD group(178 cases).The related factors affecting the occurrence of SAD were analyzed by univariate analysis and multivariate Logistic regression analysis,and risk prediction model of SAD was constructed.In addition,74 bronchial asthma children with normal pulmonary ventilation function were collected and used as the validation group.Hosmer-Lemeshow test was adopted to evaluate the calibration of the model.Receiver operating characteristic(ROC)curve was drawn and area under the curve(AUC)was calculated to evaluate the predictive efficiency of the prediction model.Results Multivariate Logistic regression analysis showed that poor asthma control(OR=10.722,95%CI:4.044-28.428),allergic rhinitis in the attack stage(OR=4.816,95%CI:1.929-12.023)and long use of inhaled corticosteroids(ICS)or ICS/long-acting β2 receptor agonist(LABA,OR=2.903,95%CI:1.269-6.643)were independent risk factors for SAD in children(P<0.05),and older age at first onset of suspected asthma symptoms(OR=0.599,95%CI:0.395-0.907)was a protective factor.Hosmer-Lemeshow test showed good calibration(χ2=8.301,P=0.307).The AUC,sensitivity and specificity of the model in the modeling group for predicting the occurrence of SAD in children with bronchial asthma were 0.820(95%CI:0.749-0.892),74.42%and 78.65%,and the AUC,sensitivity,specificity and accuracy of the model in the validation group were 0.849(95%CI:0.718-0.981),75.00%,94.83%and 90.54%(67/74).Conclusion Children with bronchial asthma who are younger at the time of their first suspected asthma symptoms,poor asthma control,allergic rhinitis in the exacerbation phase,and longer duration of use of ICS or ICS+LABA/LTRA are at higher risk of SAD.Therefore,SAD risk prediction model constructed on this basis has good predictive ability.

Objective To establish a novel localization method for sacral nerve foramen puncture by analyzing the characteristic of sacral nerve foramen trying to help improve the success rate of sacral foramen puncture.Methods Clinical data and sacrococcyx CT and three-dimensional reconstruction imaging data of 158 patients who received sacral nerve modulation(SNM)during Jan.2019 and Aug.2022 in our hospital were retrospectively analyzed.The distance between inferior margin of articulatio sacroiliaca and the internal edge of the 3rd neural foramen(D1),and the distance between the internal edge of the 3rd neural foramen and sacral midline(D2)were measured,and the ratio of D1 and D2 was calculated for precise intraoperative positioning.The measurement data characteristic and puncture results were analyzed.Results A total of 89 males and 69 females were included,with an average age of(49.0±16.9)years.The average D1,D2,and D1/D2 were(29.6±4.9)mm,(13.8±3.2)mm,and(2.2±0.6),respectively.Female patients had greater D1[(30.7±5.5)mm vs.(28.7±4.2)mm,P=0.010]and D1/D2[(2.4±0.7)vs.(2.1±0.5),P=0.001]than male patients.Compared with adults,the adolescents had smaller D1[(29.8±4.7)mm vs.(25.7±5.4)mm,P=0.006].After precise intraoperative positioning using this positioning method,158 patients were successfully punctured,152(96.20%)had excellent intraoperative neural response,2(1.27%)had good response,and 4(2.53%)had average response.Conclusion The surface projection of sacral nerve was approximately at the middle-inner 1/3 of the inferior margin of articulatio sacroiliaca to sacral midline.Through measuring distance from inferior margin of articulatio sacroiliacato sacral midline via X-ray,sacral nerve situation could be performed in surface,which might be a secure way to accessorily situate electrode implantation site for sacral neuromodulation.

The management of antibiotic-resistant, bacterial biofilm infections in skin wounds poses an increasingly challenging clinical scenario. Pseudomonas aeruginosa infection is difficult to eradicate because of biofilm formation and antibiotic resistance. In this study, we identified a new benzothiazole derivative compound, SN12 (IC50 = 43.3 nmol/L), demonstrating remarkable biofilm inhibition at nanomolar concentrations in vitro. In further activity assays and mechanistic studies, we formulated an unconventional strategy for combating P. aeruginosa-derived infections by targeting the two-component (Gac/Rsm) system. Furthermore, SN12 slowed the development of ciprofloxacin and tobramycin resistance. By using murine skin wound infection models, we observed that SN12 significantly augmented the antibacterial effects of three widely used antibiotics-tobramycin (100-fold), vancomycin (200-fold), and ciprofloxacin (1000-fold)-compared with single-dose antibiotic treatments for P. aeruginosa infection in vivo. The findings of this study suggest the potential of SN12 as a promising antibacterial synergist, highlighting the effectiveness of targeting the two-component system in treating challenging bacterial biofilm infections in humans.

OBJECTIVE: To investigate the relationship among resilience,job burnout and subject well-being( SWB) in prison staffs. METHODS: A cluster random sampling method was used to select 226 prison staffs in a city of Shandong Province as the study subjects. Chinese Adults Resilience Scale,Maslach Burnout Inventory-General Survey and General Well-Being Segment Scale were used for investigating resilience,job burnout and SWB in these subjects. RESULTS: The total score of job burnout was negatively correlated with total SWB score( P < 0. 01). The total score of resilience was positively correlated with total score of SWB( P < 0. 05). Psychological resilience,job burnout and demographic factors could explain 51. 6% of the variation of SWB. Psychological resilience plays a moderating role between job burnout and SWB( indirect effect values were-6. 27,-5. 03 and-3. 79 in the low-,medium-and high-resilience groups,respectively). CONCLUSION: Psychological resilience is helpful to reduce the occurrence of job burnout,and has a positive impact on SWB. Resilience plays a moderating role between job burnout and SWB.
