Objective:To evaluate the effect of urban-rural integrated medical insurance on rural households'catastrophic health expenditure(CHE),thereby proposing targeted optimization strategies for the integration.Methods:Based on the five tracking data of the China Household Tracking Survey(CFPS)from 2010 to 2018,Process Specification Model-Dynamic Integrity Dimension(PSM-DID)was used to empirically test the impact of urban-rural integrated medical insurance on rural households'catastrophic health expenditures.Results:The urban-rural integrated medical insurance system significantly reduces the incidence of CHE in ru-ral households.Mechanism testing indicates that health levels,human capital expenditures,and household asset accumulation are important channels of action.Conclusion:It is suggested to continuously promote the urban-rural integrated medical insurance sys-tem,formulate comprehensive policies for medical insurance according to local conditions,and incorporate catastrophic health indi-cators into the detection and warning indicator system for rural residents returning to poverty.

Objective:To explore the effect of sulforaphane (SFN) preconditioning on the cold myocardial ischemia-reperfusion injury (IRI) in the rats through PI3K/Akt signaling pathway.Methods:Sixty-four health male Sprague-Dawley (SD) rats were randomly divided into cold IRI group,SFN group,LY (LY294002) + cold IRI group,and LY+SFN group (n=16).The allogeneic heterotopic heart transplantation model was established by donor heart into recipient abdomen.The myocardium tissue was taken 24 h after reperfusion for the detection of histological changes using HE staining.The expression levels of Akt,p-Akt,Bax and Bcl-2 proteins were detected by immunohistochemistry and Western boltting methods.Results:The morphological results showed that the myocardium tissue damage was serious in cold IRI group and LY+cold IRI group,it was light in SFN group;the myocardium tissue damage of the rats in SFN+ LY group was ranged between cold IRI group and SFN group.Compared with IRI group,the expression levels of p-Akt protein and Bcl-2 protein in SFN group were increased (P<0.05),and the expression level of Bax protein was decreased (P<0.05).After treatment of blockage LY294002,compared with LY-+-cold IRI group,the expression level of p-Akt protein in LY-+-SFN group was not statistically significant (P>0.05),the expression level of Bcl2 protein was increased (P<0.05),the expression levels of Bax protein was decreased),and the ratio of Bcl-2/Bax was also increased (P<0.05).Conclusion:SFN may attenuate cold IRI of heart transplantation through PI3K/Akt signaling pathway in the rats.

Objective:To investigate the predictors of the efficacy of extracorporeal shock wave lithotripsy (ESWL) in the treatment of ureteral calculi, and to evaluate the predictive value of the maximum ureteral wall thickness (UWT) in the treatment of ureteral calculi with ESWL.Methods:The clinical data of 138 patients with ureteral calculi treated with ESWL in the Second People's Hospital of Hefei from January 2020 to December 2020 were retrospectively analyzed. There were 91 males and 47 females. The age was (50.9±14.8) years old. The body mass index was (25.3±3.6) kg/m 2. The stones of 73 cases were located on the left side and 65 cases were on the right side. 70 cases had upper ureteral stones, 18 cases had middle ureteral stones, and 50 cases had lower ureteral stones. The median length of the stone was 8.5 (7.5, 10.5) mm. The CT value of the stone was 509 (343, 783) HU. The anteroposterior diameter of the renal pelvis was 12.0 (10.1, 16.0) mm, and UWT was (2.8 ± 0.8) mm. All patients underwent urinary non-contrast CT before lithotripsy, and the UWT of the stone bed was measured on the CT images. According to the stone removal situation 2 weeks after the operation, the patients were divided into a successful lithotripsy group and a failed lithotripsy group. Univariate analysis was used to compare the differences of various indicators between the two groups, and multivariate logistic regression was used to analyze the independent predictors of ESWL in the treatment of ureteral calculi for the indicators. The receiver operating characteristic (ROC) curve was used to calculate the area under the curve (AUC) of each independent predictor, and the cut-off value, sensitivity and specificity were analyzed. Results:All operations were successfully completed, and the success rate of the first-stage lithotripsy was 71.7% (99/138). The results of univariate analysis showed that the stone length diameter, stone CT value, anteroposterior diameter of renal pelvis, stone skin distance, and UWT were significantly different between the successful lithotripsy group and the failure group ( P<0.05). There was no significant difference in age, gender, body mass index, stone side and stone location ( P>0.05). The results of multivariate logistic analysis showed that stone length ( OR=1.393, P=0.015), stone CT value ( OR=1.002, P=0.043) and UWT ( OR=17.997, P<0.001) were all for the efficacy of ESWL in the treatment of ureteral stones. The ROC curve was used to compare the three independent predictors. The area under the UWT curve was the largest (AUC=0.898, P<0.001), followed by the length of the stone (AUC=0.744, P<0.001), and the CT value of the stone (AUC=0.672, P= 0.002). The cut-off value for UWT was 3.19 mm, which had a sensitivity of 91.9% and a specificity of 71.8% for predicting the success of ESWL lithotripsy. When dividing the patients into thin wall group (UWT ≤3.19 mm) and thick wall group (UWT>3.19 mm) according to the cut-off value, the success rates of one-stage lithotripsy in the two groups were 89.2% (91 / 102) and 22.2% (8/36), respectively ( P<0.05). Conclusions:UWT, calculus length and calculus CT value are independent predictors of the efficacy of ESWL in the treatment of ureteral calculi, and UWT has the best predictive value. When UWT≤3.19 mm, the success rate of ESWL in the treatment of ureteral calculi is higher.

Objective:To describe a systematic approach on identification of poisonous mushroom by investigating two cases of Omphalotus guepiniformis poisoning in Jianyang district, Nanping, Fujian province. Methods:Two incidents of food poisoning on 10 migrant workers were investigated. The remaining suspected mushroom samples were collected and the same fresh mushroom specimens were also collected in the following field investigations from the same dead tree and fallen trunk. These mushroom specimens were identified based on morphological and phylogenetic analyses.Results:On November 24 and 26, 2018, 8 and 2 migrant workers from Jianyang District, Nanping ate wild mushrooms and developed acute nausea, vomiting, abdominal pain and other symptoms within 10 to 90 min after consumption. They were diagnosed as mushroom poisoning, with gastroenteritis as the main manifestation. Further analysis showed that the more poisonous mushroom were consumed, the shorter latency and longer duration of nausea and vomiting were resulted. After admission, gastric lavage, catharsis, acid preparation, gastric protection, fluid replenishment and other symptomatic support treatments were given in time, all patients were discharged in 1-3 d. Based on morphological and phylogenetic analyses, the samples were identified as O. guepiniformis. Conclusions:The two incidents were caused by accidental consumption of O. guepiniformis. Awareness education about poisonous mushroom should be provided to migrant workers to prevent more such poisoning incidents in the future.
