ObjectiveTo explore the therapeutic effect of Xuebijing injection （XBJ） on severe acute pancreatitis induced acute lung injury （SAP-ALI） by regulating formyl peptide receptors （FPRs）/nucleotide-binding oligomerization domain-like receptor 3 （NLRP3） inflammatory pathway. MethodsSixty rats were randomly divided into a sham group， a SAP-ALI model group， low-， medium-， and high-dose XBJ groups （4， 8， and 12 mL·kg^-1）， and a positive drug （BOC2， 0.2 mg·kg^-1） group. For the sham group， the pancreas of rats was only gently flipped after laparotomy， and then the abdomen was closed， while for the remaining five groups， SAP-ALI rat models were established by retrograde injection of 5% sodium taurocholate （Na-Tc） via the biliopancreatic duct. XBJ and BOC2 were administered via intraperitoneal injection once daily for 3 d prior to modeling and 0.5 h after modeling. Blood was collected from the abdominal aorta 6 h after the completion of modeling， and the expression of interleukin （IL）-1β， IL-6， and tumor necrosis factor-α （TNF-α） in plasma was measured by enzyme-linked immunosorbent assay （ELISA）. The amount of ascites was measured， and the dry-wet weight ratios of pancreatic and lung tissue were determined. Pancreatic and lung tissue was taken for hematoxylin-eosin （HE） staining to observe pathological changes and then scored. The protein expression levels of FPR1， FPR2， and NLRP3 in lung tissue were detected by the immunohistochemical method. Western blot was used to detect the expression of FPR1， FPR2， and NLRP3 in lung tissue. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression of FPR1， FPR2， and NLRP3 in lung tissue. ResultsCompared with the sham group， the SAP-ALI model group showed significantly decreased dry-wet weight ratio of lung tissue （P<0.01）， serious pathological changes of lung tissue， a significantly increased pathological score （P<0.01）， and significantly increased protein and mRNA expression levels of FPR1， FPR2， and NLRP3 in lung tissue （P<0.01）. After BOC2 intervention， the above detection indicators were significantly reversed （P<0.01）. After treatment with XBJ， the groups of different XBJ doses achieved results consistent with BOC2 intervention. ConclusionXBJ can effectively improve the inflammatory response of the lungs in SAP-ALI rats and reduce damage. The mechanism may be related to inhibiting the expression of FPRs and NLRP3 in lung tissue， which thereby reduces IL-1β and simultaneously antagonize the release of inflammatory factors IL-6 and TNF-α.

【Objective】 To investigate the practice and benefit of national standardized management of type 2 diabetes in Yulin City. 【Methods】 We recruited the adult type 2 diabetes patients who sought medical help at our hospital from May 2020 to October 2022 as subjects. We collected their basic information (sex and age); measured height, weight, waist and hip circumference, and blood pressure; calculated body mass index (BMI); and detected blood glucose, c-peptide, HbA1c, biomarkers, urinary microalbumin, sensory nerve conduction velocity of lower limbs, ABI, and subcutaneous and visceral fat at the time of MMC recruited and the end of six months. T test and Mann-Whitney U rank sum test were used for measurement data and χ² test or Fisher’s exact probability method for counting data to analyze the data. 【Results】 After 6 months, the levels of fasting blood glucose, postprandial blood glucose, HbA1c, and visceral and subcutaneous fat in all the patients decreased, but the level of fasting c-peptide increased compared with the baseline (all P<0.05). Secondly, compared with the baseline, the control rate of HbA1c (35.21% vs. 13.71% ) and the comprehensive control rate (13.97% vs. 7.26% ) were both significantly increased at six months (P<0.05). Thirdly, after 6 months, the levels of fasting blood glucose, postprandial blood glucose, HbA1c, TG, TC, and UA were decreased more, while the fasting c-peptide and postprandial c-peptide were increased more in the patients of the HbA1c standard group (HbA1c<7% ) than those of the non-standard group. 【Conclusion】 The multiple benefits of blood glucose, blood lipid, uric acid and islet function can be achieved by taking type 2 diabetes patients into MMC. Meanwhile, the rates of HbA1c control and comprehensively reaching the standard are significantly increased. Therefore, MMC can explore a new way for the management of type 2 diabetic patients in this area.

Objective: To analyze the existing problems in the construction of pneumoconiosis rehabilitation station in Beijing under the framework of ecosystem theory, and put forward countermeasures. Methods: A total of four managers directly involved in the construction of three pneumoconiosis rehabilitation stations in Beijing and 12 rehabilitation doctors working in rehabilitation stations were selected as the interviewees using the judgment sampling method. Based on the perspective of ecosystem theory, an interview outline was designed to conduct a semi-structured interview with the interview subjects. In combination with literature data, the current situation, existing problems and solutions of pneumoconiosis rehabilitation station construction were analyzed. Results: There were still deficiencies in the construction of pneumoconiosis rehabilitation stations in Beijing. At the microscale level, pneumoconiosis patients could not make full use of family resources for active and effective pulmonary rehabilitation treatment, and family members lack of effective rehabilitation guidance and assistance for patients. At the medium-scale level, the resources of primary rehabilitation institutions were insufficient, the medical support for pneumoconiosis rehabilitation was insufficient, and the pneumoconiosis rehabilitation stations lacked a unified information management and technology platform. At the macroscale level, it has not established clear and specific requirements for the construction management and evaluation of pneumoconiosis rehabilitation stations, and there was social discrimination and prejudice against pneumoconiosis patients. Conclusion: It is necessary to improve the recognition of rehabilitation in primary medical and health institutions, strengthen education on the awareness of the disease and rehabilitation skills guidance for patients and their families, strengthen the responsibilities of technical support institutions in rehabilitation stations, promote the construction of primary rehabilitation stations and personnel training, make full use of information technology, promote information exchange and knowledge sharing, and ensure the quality of rehabilitation of pneumoconiosis.

【Objective】 To investigate the control rate of blood glucose and its influencing factors in type 2 diabetes mellitus patients in Yulin area. 【Methods】 We selected the adult type 2 diabetes patients who visited our hospital from May 2020 to December 2021 as the subjects. Then we collected their basic information (gender, age, household income, type of medical insurance payment, education level, and duration of disease), measured their height and weight, calculated their body mass index (BMI), detected HbA1c, and measured their subcutaneous and visceral fat. The Chi-square test and multivariate Logistic regression methods were used to analyze the influencing factors. 【Results】 The total attainment rate of HbA1c (HbA1c<7%) among 877 adults with type 2 diabetes was 13.34%. The Chi-square test showed that statistical differences in the attainment rate of HbA1c among different ages, family annual income, type of medical insurance, and duration of disease. Further unconditional multivariate Logistic regression analysis model results showed that the HbA1c attainment rate in 18-44 years old group was 0.418 times higher than that in ≥60 years old group (95% CI=0.219-0.799, P=0.008). The HbA1c compliance rate of patients with employees’ medical insurance was 1.744 times that those with residents’ medical insurance (95% CI=1.131-2.782, P=0.013). The HbA1c attainment rate of diabetic patients with an annual family income of 30 000 yuan to 100 000 yuan was 1.873 times (95% CI=1.074-3.266, P=0.027), and with an annual family income of more than 100 000 yuan was 2.649 (95% CI=1.299-5.404, P=0.007) times than that of diabetic patients with less than 30 000 yuan. 【Conclusion】 The blood glucose control rate in adults with type 2 diabetes mellitus in Yulin area is lower compared with the level of the nation and other regions. Age, annual household income, and type of medical insurance payment are independent influencing factors.

Objective:To explore the independent risk factors of poor healing of surgical incisions in patients with drainage tube removal after thoracic and abdominal surgery and establish a risk prediction model for poor healing of surgical incisions.Methods:Using the convenient sampling method, a total of 545 patients who underwent thoracic and abdominal surgery in the Affiliated Hospital of Qingdao University were selected from July to December 2020. The patients were divided into the poor wound healing group ( n=87) and the non-incision poor healing group ( n=458) according to whether they had poor wound healing. Logistic regression analysis was used to analyze the risk factors of poor healing of surgical incisions and build a risk prediction model. The receiver operating characteristic (ROC) area under the curve was used to test the model to predict the effect and 230 patients were selected to verify the model prediction effect. Results:In this study, 5 factors including duration of exudation, serum albumin, incision infection, the volume of exudation during catheterization and catheterization time were finally included to construct a risk prediction model. The model formula was Z=4.608+4.855× duration of exudation +3.173× serum albumin +3.739× infection of the incision +2.271×the volume of exudation during catheterization + 0.466× catheterization time. The area under ROC curve of this model was 0.773 (95% CI: 0.678 - 0.868). The maximum value of Youden index was 0.549, the sensitivity was 0.742 and the specificity was 0.807. Conclusions:The risk prediction model of poor incision healing after drainage tube removal for patients undergoing thoracic and abdominal surgery can better predict the risk of poor incision healing and provide a basis for clinical medical staff to take preventive management measures for high-risk patients in time.

Purpose: The purpose of the current study was to explore the functions and potential mechanism of miR-451a in breast cancer (BC). Methods: Quantitative reverse transcription real-time polymerase chain reaction was used to analyze the expression of miR-451a in human normal mammary cells (MCF-10A) and BC cells. Colony formation assay, terminal-deoxynucleoitidyl transferase mediated nick end labeling assay and transwell assays were conducted to validate the effect of miR-451a on proliferation, apoptosis, migration and invasion of BC cells, respectively. RNA pull-down, RNA immunoprecipitation and luciferase reporter assays were applied to investigate the upstream and downstream mechanisms of miR-451a in BC cells. Results: MiR-451a was expressed at a low level in BC cells. Overexpression of miR-451a repressed BC cells proliferation, migration and invasion. Moreover, long non-coding RNA AC092127.1 acted as a sponge of miR-451a to enhance the expression level of AE binding protein 2 (AEBP2) that was demonstrated to be the target gene of miR-451a in BC cells. Finally, rescue experiments validated that miR-451a and AEBP2 involved in AC092127.1-mediated BC cell growth, migration and invasion. Conclusion In a word, AC092127.1/miR-451a/AEBP2 axis contributes to BC cell growth, migration and invasion. Our results may help to find novel potential targets for BC treatment.
