OBJECTIVE To study the therapeutic effect of Hongqi Shenmai Drink on heart failure(HF)after acute myocardial in-farction(AMI)with qi-yin deficiency and blood stasis,and its regulatory effect on serum secretory phosphoprotein 1(SPP1)in AMI-HF patients.METHODS Seventy-six patients with AMI-HF of qi-yin deficiency and blood stasis type were enrolled in this study from three centers:Affiliated Hospital of Integrated Traditional and Western Medicine,Nanjing University of Chinese Medicine;Hangzhou Xiaoshan Hospital of Traditional Chinese Medicine;and Changzhou Hospital of Traditional Chinese Medicine.They were randomly di-vided into a traditional Chinese medicine(TCM)group and a control group,with 38 patients in each group.During the treatment period,4 patients in the TCM group and 3 patients in the control group dropped out.The control group received conventional Guideline-directed medical therapy(GDMT),while the TCM group received GDMT plus Hongqi Shenmai Drink.The treatment course for both groups was 12 weeks.The TCM syndrome scores of the two groups of patients were compared before and after treatment,and the clini-cal efficacy and readmission rate were assessed.Echocardiography was used to assess cardiac structure and function.ELISA was used to detect changes in serum SPP1,N-terminal pro-brain natriuretic peptide(NT-proBNP),interleukin-1β(IL-1β),type Ⅰ collagen α1(COL1α1),and matrix metalloproteinase 9(MMP9)levels.The 6-minute walk test(6MWT)was used to assess exercise tolerance,and the Minnesota living with heart failure questionnaire(MLHFQ)was used to assess patients'quality of life.Adverse reactions were monitored in both groups during treatment.RESULTS After treatment,the TCM syndrome scores of both groups decreased signifi-cantly(P<0.01),with the TCM group showing a significantly lower score than the control group(P<0.01).The total effective rate of TCM clinical efficacy in the TCM group was superior to that in the control group(P<0.05),and the readmission rate in the TCM group was significantly lower than that in the control group(P<0.01).Left ventricular end diastolic diameter(LVEDD),left ventricular end-systolic diameter(LVESD),left ventricular ejection fraction(LVEF),6MWT,and MLHFQ scores improved in both groups(P<0.01),with the TCM group showing superior improvement compared to the control group(P<0.05,P<0.01).Serum levels of NT-proBNP,IL-1β,COL1α1,and MMP9 decreased in both groups(P<0.05,P<0.01).Serum SPP1 levels were significantly decreased in the TCM group(P<0.01),and serum levels of NT-proBNP,IL-1β,COL1α1,and MMP9 in the TCM group were significantly lower than those in the con-trol group(P<0.01).The change in SPP1(ΔSPP1)showed a negative correlation with the change in the cardiac function ΔLVEF(r=-0.42,P<0.01),and a positive correlation with the myocardial fibrosis marker ΔCOL1α1(r=0.58,P<0.01)and the matrix degradation marker ΔMMP9(r=0.51,P<0.01).There was no significant difference in adverse reaction rates between the two groups during treat-ment(P>0.05).CONCLUSION Hongqi Shenmai Drink combined with GDMT can effectively improve clinical symptoms and cardiac function in patients with AMI-HF of qi-yin deficiency and blood stasis type,with good safety.Its mechanism may be related to the in-hibition of SPP1-mediated inflammation-fibrosis pathway and the downregulation of IL-1β,COL1α1,and MMP9 expression.

Objective:To compare the embrace fixation and screw fixation in the treatment of inferior tibiofibular syndesmosis injury.Methods:A retrospective study was conducted of the 125 patients who had been treated for ankle fractures and distal syndesmotic injuries at The Hospital Affiliated to Qingdao University from April 2018 to September 2021. They were 79 males and 46 females with an age of (25.4±11.2) years. The patients were divided into 2 groups according to their fixation methods: an observation group of 75 cases subjected to embrace fixation and a control group of 50 cases subjected to conventional screw fixation. Their reduction was evaluated by comparing the disparities between the affected and normal sides in the anterior and posterior syndesmotic distances, fibular translation distance, and fibular rotation angle between the 2 groups after surgery. Intraoperative immobilization time for the inferior tibiofibular syndesmosis, American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, Olerud-Molander ankle function score, and visual analog scale (VAS) for pain were also compared at the last follow-up between the 2 groups.Results:There was no statistically significant difference in the preoperative baseline data between the 2 groups of patients, indicating comparability ( P>0.05). There was no statistically significant difference between the 2 groups in intraoperative immobilization time for the inferior tibiofibular syndesmosis, disparity between the injured and normal sides in postoperative fibular translation distance, or VAS pain score at the last follow-up ( P>0.05). The anterior and posterior syndesmotic distances, disparity between the injured and normal sides in fibular rotation angle, AOFAS ankle-hindfoot score, and Olerus-Molander ankle function score in the observation group [0.1 (-0.2, 0.3) mm, 0.1 (-0.3, 0.5) mm, -0.5 (-1.1, 0.8)°, 96 (93, 100) points, and 95 (90, 100) points] were all significantly better than those in the control group [1.4 (0.6, 2.1) mm, 1.5 (0.9, 2.2) mm, 1.2 (-3.8, 3.7)°, 93 (89, 96) points, and 90 (85, 100) points] (all P<0.05). There was no major complication or nonunion in the observation group. Conclusion:The embrace technique can provide an accurate and effective fixation for the inferior tibiofibular syndesmosis in patients with ankle fracture and lead to better clinical and radiographic outcomes than conventional screw fixation.

Objective To explore the application value of prognostic nutritional index (PNI) in the postoperative complications of McKeown surgery for da Vinci robotic esophageal cancer. Methods The clinical data of the patients who underwent da Vinci robotic McKeown surgery for esophageal cancer in the Department of Thoracic Surgery of the First Hospital of Lanzhou University from January 2019 to June 2022 were retrospectively collected. According to the receiver operating characteristic (ROC) curve, the optimal cut-off value of PNI for predicting postoperative complications was explored. The patients were divided into a high PNI group and a low PNI group according to the cut-off value, and the differences in basic characteristics, surgery-related indexes and postoperative complications between the two groups were analyzed. According to the occurrence of postoperative complications, the patients were divided into a non-complication group and a complication group. Univariate and multivariate analyses were used to explore the influence of relevant indicators on the occurrence of postoperative complications in da Vinci robotic McKeown surgery for esophageal cancer. Results Finally 120 patients were collected, including 95 males and 25 females, with an average age of 62.82 years. The preoperative hemoglobin content, preoperative blood lymphocyte count, preoperative serum albumin and preoperative blood total cholesterol in the high PNI group were higher than those in the low PNI group (P<0.05). There were statistical differences between the two groups in the incidences of postoperative overall complications, pulmonary infection, pleural effusion and poor incision healing (P<0.05). The relevant indicators that may cause postoperative complications were included in univariate analysis, and the results showed that age, operation time, intraoperative blood loss, preoperative blood lymphocyte count, preoperative hemoglobin content, preoperative blood mononuclear cell count, preoperative blood monocyte count, serum albumin level and PNI were possible influencing factors of postoperative complications after da Vinci robotic McKeown surgery for esophageal cancer. Incorporating these influencing factors into multivariate analysis, the results showed that age, PNI, operation time and intraoperative blood loss were independent influencing factors of postoperative complications. Conclusion PNI has certain predictive value in the postoperative complications of da Vinci robotic McKeown surgery for esophageal cancer. PNI is an independent factor affecting postoperative complications. Improving the level of PNI in esophageal cancer patient before surgery may help reduce the occurrence of postoperative complications.

Objective To investigate the effect of multi-sided foramen ultrafine drainage tube with metal support on the formation of thoracic residual cavity after uniportal video-assisted thoracoscopic (VATS) upper lobectomy. Methods The clinical data of the patients who underwent uniportal VATS upper lobectomy for lung cancer in the Department of Thoracic Surgery of the First Hospital of Lanzhou University from January 2021 to April 2022 were retrospectively analyzed. According to the type of ultrafine drainage tube used in the surgery, the patients were divided into a test group (using metal-supported multi-sided foramen ultrafine drainage tube) and a control group (using ordinary 12F ultrafine drainage tube). The incidence of postoperative thoracic residual cavity and operation-related data were compared between the two groups. Results A total of 200 patients were enrolled, including 126 males and 74 females, with a mean age of 57.52 years. There were 90 patients in the test group, and 110 patients in the control group. The incidence of postoperative thoracic residual cavity in the test group was lower than that in the control group (P=0.045). The differences in the postoperative bedtime, postoperative visual analogue scale, postoperative analgesic pump using time, postoperative hospitalization time, times of postoperative thoracentration and drainage, postoperative drainage time and hospitalization cost between the two groups were statistically significant (P<0.05). The incidences of postoperative lung infection, pleural effusion and atelectasis complications were lower in the test group than those in the control group (P<0.05). The differences in the preoperative anesthesia time, operation time, intraoperative bleeding and postoperative lung leakage were not statistically significant (P>0.05). Conclusion The use of multi-sided foramen ultrafine drainage tube with metal support can reduce the incidence of thoracic residual cavity after uniportal VATS upper lobectomy, and can reduce pain and economical burdens and the incidence of operation-related complications, accelerating the recovery of patients after surgery. The application of multi-sided foramen ultrafine drainage tube with metal support in uniportal VATS upper lobectomy can be widely used in the clinic.

Purpose To explore the application value of combining 18F-FDG PET images with interpretable deep learning radiomics(IDLR)models in the differential diagnosis of primary Parkinson's disease(IPD)and atypical Parkinson's syndrome.Materials and Methods This cross-sectional study was conducted using the Parkinson's Disease PET Imaging Benchmark Database from Huashan Hospital,Fudan University from March 2015 to February 2023.A total of 330 Parkinson's disease patients underwent 18F-FDG PET imaging,both 18F-FDG PET imaging and clinical scale information were collected for all subjects.The study included two cohorts,a training group(n=270)and a testing group(n=60),with a total of 211 cases in the IPD group,59 cases in the progressive supranuclear palsy(PSP)group,and a group of 60 patients with multiple system atrophy(MSA).The clinical information between different groups were compared.An IDLR model was developed to extract feature indicators.Under the supervision of radiomics features,IDLR features were selected from the features collected by neural network extractors,and a binary support vector machine model was constructed for the selected features in images of in testing group.The constructed IDLR model,traditional radiomics model and standard uptake ratio model were separately used to calculate the performance metrics and area under curve values of deep learning models for pairwise classification between IPD/PSP/MSA groups.The study conducted independent classification and testing in two cohorts using 100 10-fold cross-validation tests.Brain-related regions of interest were displayed through feature mapping,using gradient weighted class activation maps to highlight and visualize the most relevant information in the brain.The output heatmaps of different disease groups were examined and compared with clinical diagnostic locations.Results The IDLR model showed promising results for differentiating between Parkinson's syndrome patients.It achieved the best classification performance and had the highest area under the curve values compared to other comparative models such as the standard uptake ratio model(Z=1.22-3.23,all P<0.05),and radiomics model(Z=1.31-2.96,all P<0.05).The area under the curve values for the IDLR model in differentiating MSA and IPD were 0.935 7,for MSA and PSP were 0.975 4,for IPD and PSP were 0.982 5 in the test set.The IDLR model also showed consistency between its filtered feature maps and the visualization of gradient-weighted class activation mapping slice thermal maps in the radiomics regions of interest.Conclusion The IDLR model has the potential for differential diagnosis between IPD and atypical Parkinson's syndrome in 18F-FDG PET images.

China's healthcare payment reform seeks to combine a medical insurance point-system with a global budget.The focus and difficulty in implementing the payment reform is how to make effectively link.On the basis of theoretical analysis,it selects the regions that have implemented the payment by disease under regional total budget and the payment by disease under institutional total budget,and summarizes the synergistic mechanism of total budget and payment by disease,including the strict control of total budget at the regional level,the reasonable setup of the budget or the standard of expected service volume at the institutional level,and the rate fluctuation and discount mechanism for the settlement of excess service;and further sort out the additional incentive mechanism to support innovation and quality enhancement under the background of the total budget and the payment by disease.Lessons can be drawn from the experiences of typical regions to strengthen the synergy between regional budgets,institutional budgets and payment by type of disease,and cautiously deal with the risks of excessive competition and"punching points"that may arise from the regional point method.
