Objective To investigate the effect of kakkonein on the expression of NF-?B after hepatic ischemia reperfusion injury in rats.Methods Male Sprague-Dawley rats were randomly divided into three groups:pseudo-operation normal control group,hepatic ischemia reperfusion injury model group,kakkonein group.After hepatic ischemia and reperfusion,we analyzed the expression of NF-?B by the methods of Western blot and RT-PCR.Results After hepatic ischemia reperfusion,the NF-?B level increased obviously comparing with the normal group.Comparing to the hepatic ischemia reperfusion injury model group,the NF-?B level decreased after treated with kakkonein.Conclusion The apigenin has a prominent protective effect on hepatic ischemia reperfusion injury in rats through regulating the expression of NF-?B.

To explore the differences, causes and countermeasures for mental patients' life quality between developed and developing regions.
 Methods: Based on the Quality of Life Questionnaire for Psychiatric Patients (QOL-P) and adopting convenient random sampling method, a total of 340 mental patients in Shanghai and Guangxi were investigated, and the data were analyzed by methods of Paired Design Crosstabulation Data hypothesis test, multivariate logistic regression, and independent sample Kruskal-Wallis test. The differences in patients' life quality in the 2 regions and the influential factors were evaluated.
 Results: There were high consistency and correlation in the total scores of self-evaluation items G (self overall evaluation of life quality by patient) between the 2 regions. Region and gender significantly affected mental patients' life quality in the basic demography characteristics in the 2 regions. The differences between total scores of 4 independent samples grouped by region and sex were significant (P<0.01). The male and femal patients in Guangxi in the dimensions of physiology, psychology, society and symptom were better than those in Shanghai (P<0.01). There was certain homoplasy between the patients from Shanghai and those from Guangxi in terms of the most prominent matters that affect the mental patients' life quality, with the former being affected more seriously than the latter.
 Conclusion: To a certain extent, the mental patients' life quality in the developing region (Guangxi) is better than that in the developed region (Shanghai).

Objective     To explore the correlation between the quantitative and qualitative features of CT images and the invasiveness of pulmonary ground-glass nodules, providing reference value for preoperative planning of patients with ground-glass nodules. Methods    The patients with ground-glass nodules who underwent surgical treatment and were diagnosed with pulmonary adenocarcinoma from September 2020 to July 2022 at the Third Affiliated Hospital of Kunming Medical University were collected. Based on the pathological diagnosis results, they were divided into two groups: a non-invasive adenocarcinoma group with in situ and minimally invasive adenocarcinoma, and an invasive adenocarcinoma group. Imaging features were collected, and a univariate logistic regression analysis was conducted on the clinical and imaging data of the patients. Variables with statistical difference were selected for multivariate logistic regression analysis to establish a predictive model of invasive adenocarcinoma based on independent risk factors. Finally, the sensitivity and specificity were calculated based on the Youden index. Results     A total of 555 patients were collected. The were 310 patients in the non-invasive adenocarcinoma group, including 235 females and 75 males, with a meadian age of 49 (43, 58) years, and 245 patients in the invasive adenocarcinoma group, including 163 females and 82 males, with a meadian age of 53 (46, 61) years. The binary logistic regression analysis showed that the maximum diameter (OR=4.707, 95%CI 2.060 to 10.758), consolidation/tumor ratio (CTR, OR=1.027, 95%CI 1.011 to 1.043), maximum CT value (OR=1.025, 95%CI 1.004 to 1.047), mean CT value (OR=1.035, 95%CI 1.008 to 1.063), spiculation sign (OR=2.055, 95%CI 1.148 to 3.679), and vascular convergence sign (OR=2.508, 95%CI 1.345 to 4.676) were independent risk factors for the occurrence of invasive adenocarcinoma (P<0.05). Based on the independent predictive factors, a predictive model of invasive adenocarcinoma was constructed. The formula for the model prediction was: Logit(P)=–1.293+1.549×maximum diameter of lesion+0.026×CTR+0.025×maximum CT value+0.034×mean CT value+0.72×spiculation sign+0.919×vascular convergence sign. The area under the receiver operating characteristic curve of the model was 0.910 (95%CI 0.885 to 0.934), indicating that the model had good discrimination ability. The calibration curve showed that the predictive model had good calibration, and the decision analysis curve showed that the model had good clinical utility. Conclusion     The predictive model combining quantitative and qualitative features of CT has a good predictive ability for the invasiveness of ground-glass nodules. Its predictive performance is higher than any single indicator.

Objective To investigate the awareness of malaria-related knowledge, the use of mosquito nets and their influencing factors among residents in Banlao Township, Cangyuan County, Yunnan Province.. Methods In August 2020, 19 settlement sites in Banlao Township, Cangyuan County, Lincang City, Yunnan Province were selected as study areas, and permanent residents at ages of 10 years and older were enrolled for a questionnaire survey, including residents’ demographics, family economic status, malaria control knowledge and use of mosquito nets. In addition, the factors affecting the use of mosquito nets in the night prior to the survey were identified using multivariate logistic regression analysis. Results A total of 320 questionnaires were allocated, and all were recovered (a 100% recovery rate). There were 316 valid questionnaires, with an effective recovery rate of 98.75%. The 316 respondents included 152 men and 164 women and 250 Chinese respondents and 66 foreign respondents. The awareness of clinical syndromes of malaria was significantly higher among Chinese residents (71.60%) than among foreign residents (50.00%) (χ² = 11.03, P < 0.01), and the proportions of Chinese and foreign residents sleeping under mosquito nets were 46.00% and 69.70% on the night prior to the survey, respectively (χ² = 11.73, P < 0.01). Multivariate logistic regression analysis identified ethnicity group and type of residence as factors affecting the use of mosquito nets in the night prior to the survey. Conclusions The awareness of malaria control knowledge, the coverage and the use of mosquito nets were low among residents in Banlao Township, Cangyuan County, Yunnan Province. Targeted health education is recommended to improve the awareness of malaria control knowledge and self-protection ability. In addition, improving the allocation of long-lasting mosquito nets and health education pertaining to their uses and increasing the proportion of using mosquito nets correctly is needed to prevent re-establishment of imported malaria.
