Objective:To evaluate the relationship between silence information regulator 1 (SIRT1) and NOD-like receptor protein 3 (NLRP3) inflammasomes during myocardial ischemia-reperfusion (I/R) in diabetic rats.Methods:SPF-grade healthy male Sprague-Dawley rats, aged 6-8 weeks, weighing 200-220 g, were used in this study.Type 1 diabetes mellitus was induced by intraperitoneal 1% streptozotocin diluted in citrate buffer solution 60 mg/kg.The rats were continuously fed for 8 weeks after successful establishment of the model.Forty-two rats with type 1 diabetes mellitus were divided into 4 groups by a random number table method: diabetic sham operation group (DS group, n=6), diabetic myocardial I/R group (DIR group, n=12), diabetic myocardial I/R plus SIRT1 agonist SRT1720 group (DIR+ SR group, n=12) and diabetic myocardial I/R plus SIRT1 inhibitor EX-527 group (DIR+ EX group, n=12). Eighteen non-diabetic rats were divided into 2 groups by a random number table method: non-diabetic sham operation group (NS group, n=6) and non-diabetic myocardial I/R group (NIR group, n=12). The myocardial I/R model was established by ligation of the left anterior descending coronary artery for 30 min followed by 120-min reperfusion in anesthetized rats.Blood samples were collected from the carotid artery immediately after the end of reperfusion for determination of serum troponin I (cTnI), creatine kinase-MB (CK-MB) and lactate dehydrogenase (LDH) levels (by enzyme-linked immunosorbent assay). Then the rats were sacrificed, and myocardial tissues were obtained for determination of myocardial infarct size (by TTC method) and expression of SIRT1, NLRP3 and IL-1β (by Western blot) and for microscopic examination of pathological changes of myocardial tissues (by HE staining). The percentage of myocardial infarct size was calculated. Results:Compared with group NS, the serum levels of cTnI, CK-MB and LDH were significantly increased, the expression of SIRT1 in myocardial tissues was down-regulated, and the expression of NLRP3 and IL-1β was up-regulated in group NIR ( P<0.05). Compared with group DS, the serum levels of cTnI, CK-MB and LDH were significantly increased, the expression of SIRT1 in myocardial tissues was down-regulated, and the expression of NLRP3 and IL-1β was up-regulated in group DIR ( P<0.05). Compared with group NIR, the percentage of myocardial infarct size and serum levels of cTnI, CK-MB and LDH were significantly increased, the expression of SIRT1 in myocardial tissues was down-regulated, the expression of NLRP3 and IL-1β was up-regulated ( P<0.05), and the pathological changes were accentuated in group DIR.Compared with group DIR, the percentage of myocardial infarct size and serum levels of cTnI, CK-MB and LDH were significantly decreased, the expression of SIRT1 in myocardial tissues was up-regulated, the expression of NLRP3 and IL-1β was down-regulated ( P<0.05), and the pathological changes were significantly attenuated in group DIR+ SR, and the percentage of myocardial infarct size and serum levels of cTnI, CK-MB and LDH were significantly increased, the expression of SIRT1 in myocardial tissues was down-regulated, the expression of NLRP3 and IL-1β was up-regulated ( P<0.05), and the pathological changes were accentuated in group DIR+ EX. Conclusion:The up-regulated expression of SIRT1 can inhibit the activation of NLRP3 inflammasomes and produces endogenous protection during myocardial I/R in diabetic rats.

Objective:To study the influence of the choice of main diagnosis on diagnosis-related groups(DRG) grouping and weight change, by taking cerebral infarction as the entry point.Methods:From January 1, 2019 to March 31, 2019, 331 patients in three DRG groups(BR25, BR23, BR21) with cerebral infarction were selected. The original group was used as the control group; the main diagnosis was exchanged with the first other diagnosis, then DRG group was used as the experimental group. The difference of the number of cases and weight between the two groups was analyzed.Results:41.4%(137/331) of the patients in the experimental group were enrolled in BZ11 with other neurological disorders associated with important comorbidities and comorbidities, and 82.5%(273/331) patients′ weight increased after diagnostic conversion.Conclusions:Choosing other diagnosis as the main diagnosis may change the weight of the disease and affect the corresponding disease benefit. In order to prevent downcoding, DRG grouping should be detailed, and DRG payment should consider how to reflect the value of difficult cases; for upcoding behavior, medical insurance center and relevant medical institutions should check the correctness of coding, and monitor in place.

Objective:To evaluate the medical service quality of psychiatric hospitals in Beijing based on diagnostic related group (DRG), analyze the evaluation effect, for refences to constructe a DRG performance evaluation system suitable for psychiatric hospitals.Methods:This study extracted data such as the number of DRG groups, etc. of hospitalized patients in 14 tertiary and secondary psychiatric hospitals in Beijing from 2018 to 2020 from the Beijing inpatient medical performance evaluation platform, and analyzed data on DRG performance evaluation indicators, as well as the average length of hospital stay and average cost of DRG enrolled cases. All data were analyzed using descriptive research methods, and inter group comparisons were conducted using the Mann Whitney U-test. Results:From 2018 to 2020, the average number of DRG groups in tertiary hospitals (28) was higher than that in secondary hospitals (10) ( P<0.05), and the average CMI values of both were the same(1.79); The average cost consumption index (1.15) of tertiary hospitals was higher than that of secondary hospitals (0.65) ( P<0.05), while the average time consumption index (1.11) was slightly lower than that of secondary hospitals (1.30); The mortality rate of the low-risk group in tertiary hospitals (0.01%) was generally lower than that in secondary hospitals (0.88%), and the average percentage of DRG admitted inpatients (82.8%) was significantly higher than that in secondary hospitals (27.3%) ( P>0.05). The average length of stay and cost per case for DRG enrolled inpatients in tertiary and secondary hospitals were lower than the overall hospital discharge cases ( P<0.05). Conclusions:The number of DRG groups, CMI value, and low-risk mortality rate could be used for evaluating the medical service capacity and safety of psychiatric hospitals, but the cost and time consumption index could not objectively reflect the efficiency of hospital medical services. DRG performance evaluation indicators are more suitable for evaluating short-term hospitalization of psychiatric patients. The proportion of DRG enrolled cases might be a potential indicator for evaluating the service quality of psychiatric hospitals.
