Objective To explore the clinical value of the platelet count(PLT)to high-density lipoprotein cholesterol(HDL-C)ratio(PHR)in predicting poor prognosis after intravenous thrombolysis in patients with acute cerebral infarction(ACI).Methods A total of 304 patients with ACI who received intravenous thrombolytic therapy in this hospital from January 2021 to December 2023 were selected as the research sub-jects.According to the modified Rankin scale score at 6-month follow-up,the 304 patients with ACI were di-vided into the good prognosis group(n=216)and the poor prognosis group(n=88).Clinical data of all pa-tients were collected.The levels of PLT,HDL-C and PHR were compared between the two groups.The pre-dictive value of PLT,HDL-C and PHR for the prognosis of ACI patients was analyzed by using the receiver operating characteristic(ROC)curve.Binary Logistic stepwise regression analysis was used to explore the in-fluencing factors of prognosis in ACI patients.Results Compared with the good prognosis group,the HDL-C level in the poor prognosis group decreased,while the PLT level and PHR increased(P＜0.05).The results of the ROC curve showed that the area under the curve(AUC)and 95％CI of PLT,HDL-C,and PHR for pre-dicting poor prognosis after intravenous thrombolysis in ACI patients was 0.829(0.784-0.874),0.743(0.693-0.788),and 0.918(0.873-0.968),respectively.The AUC of PHR in predicting poor prognosis af-ter intravenous thrombolysis in ACI patients was higher than that of PLT and HDL-C alone(Z=13.239,10.776,P＜0.001).The proportions of National Institutes of Health Stroke Scale(NIHSS)score ≥8 points at admission,transformation of previous symptomatic hemorrhage,combined hypertension,and combined dia-betes in the poor prognosis group were all higher than those in the good prognosis group(P＜0.05).The re-sults of binary Logistic stepwise regression showed that the NIHSS score at admission(OR=2.565,95％CI:1.292-5.094),the transformation of previous symptomatic hemorrhage(OR=2.073,95％CI:1.179-8.645),and PHR(OR=3.732,95％CI:2.037-6.839)were risk factors for poor prognosis in ACI patients(P＜0.05).Conclusion PHR is expected to become an important reference index for predicting the prognosis of ACI patients after intravenous thrombolysis therapy.PHR,NIHSS score at admission,and the transforma-tion of previous symptomatic hemorrhage are all influencing factors for the prognosis of ACI patients after in-travenous thrombolysis therapy.

Objective It screens the main factors influencing the choice of the governance structure of the medical alliances,and discusses the matching relationship between the type of governance structure and the performance of the medical alliances,which provides a reference for further promoting the medical alliances.Methods The text coding analysis of interview data from hospital administrators of 54 medical institutions was analyzed using the rooting theory,and 150 medical alliances were selected for questionnaire surveys using convenience sampling to analyze the performance of the medical alliances and the relationship with the choice of the type of governance structure using descriptive statistics,nonparametric tests,factor analysis,and multivariate linear regression.Results The results show that the following factors affect the selection of the governance structure of medical alliances:asset specificity,transaction frequency and uncertainty;regardless of the type of governance structure of the medical alliances,asset specificity and uncertainty both significantly and positively influence the performance of medical alliances.Under the governance structure of the property-type alliance,transaction frequency has no statistically significant effect on the performance of the medical alliances.Conclusion Enhancing the positive impact of asset exclusivity and uncertainty on the performance of medical alliances.

Objective:To investigate the value of ultrasound findings in the diagnosis of lower extremity arterial disease in patients with type 2 diabetes mellitus and correlate it with clinical factors.Methods:A total of 535 patients with type 2 diabetes mellitus who received treatment in Taiyuan Second People's Hospital from January 2016 to June 2019 underwent color Doppler ultrasound examination (T2DM group). Vascular inner diameter, intima-media thickness, atherosclerotic plaque formation, lumen stenosis or occlusion, and hemodynamic characteristics were determined in patients with type2 diabetes mellitus compared with those in 107 patients with non-type 2 diabetes mellitus (non-T2DM group). These parameters were correlated with the course of the disease, blood glucose level, concomitant hypertension or not, and clinical Wagner grade.Results:The incidences of intima-media thickening, atherosclerotic plaque, stenosis, and occlusion of lower extremity arteries were 69.9%, 89.0%, 77.0% and 11.6% respectively, in the T2DM group, which were significantly higher than 41.1%, 78.5%, 72.0%, and 1.9% respectively in the non-T2DM group ( χ2 = 32.52, P < 0.001; χ2 = 8.76, P = 0.003; χ2 = 27.77, P < 0.001). With the prolongation of the course of T2DM, the incidence of arterial lesions in the lower extremities increased ( P < 0.001). The incidences of intima-media thickening, atherosclerotic plaque, stenosis, and occlusion of lower extremity arteries were significantly greater in the poor blood glucose control group and non-hypertension group compared with the good blood glucose control group and hypertension group (all P < 0.05). The degree of lower extremity arterial stenosis in T2DM patients was related to Wagner's grade. As the degree of stenosis increased, Wagner's grade increased correspondingly and significantly ( P < 0.001). Conclusion:Color Doppler ultrasound examination has an important value in evaluating lower extremity arterial lesions in patients with T2DM. The degree of arterial lesions in the lower extremities of T2DM patients is correlated with the course of the disease, blood glucose levels, concomitant hypertension, and clinical Wagner grade. Color Doppler ultrasound examination has an important clinical significance in evaluating the degree of vascular lesions and guiding early interventions in the clinic.
