Objective To develop a predictive model for assessment of the risk of the patients on prolonged mechanical ventilation after coronary artery bypass grafting with extracorporeal circulation.Methods A convenience sampling method was employed to select 2 334 patients who received the coronary artery bypass grafting(CABG)with extracorporeal circulation in our hospital from January 2021 to December 2023 as the study subjects.Preoperative,intraoperative and postoperative data were collected through structured queries from the electronic medical record system of hospital.The study subjects were randomly divided into a training set(n=1 633)and a validation set(n=701)following a 3:1 ratio.A risk prediction model was established using Logistic regression based on the training set data.Model fit was assessed using Hosmer-Lemeshow test,and predictive performance of the model was evaluated with the area under curve(AUC)of the receiver operating characteristic(ROC)curve.Results A total of 2,334 patients were included,of whom 215(9.2%)experienced the prolonged mechanical ventilation(>24 hours).The model developed from the training set identified seven factors that contributed to a prolonged mechanical ventilation:age(OR=1.03),body mass index(BMI,OR=1.14),time of extracorporeal circulation(OR=1.01),intraoperative blood transfusion(OR=4.15),postoperative serum total bilirubin(OR=1.08),postoperative serum albumin(OR=0.92)and postoperative re-sternotomy(OR=5.49).The AUC of the model for prediction of prolonged mechanical ventilation after CABG with extracorporeal circulation was 0.761,with a 95%CI of 0.716-0.806,a maximum Youden index of 0.105,a sensitivity of 77.94%,and a specificity of 64.38%.Validation using the validation set data yielded an AUC of 0.733,with a 95%CI of 0.662-0.804,a sensitivity of 75.32%,a specificity of 57.97%,and a predictive accuracy of 73.61%.Conclusion The risk prediction model developed in this study for prolonged mechanical ventilation after a CABG with extracorporeal circulation demonstrates a good predictive performance.It provides a reference for the nurses to identify the patient in high-risk of prolonged mechanical ventilation after a CABG with extracorporeal circulation and to implement preventive nursing measures.

Objective To investigate the efficacy of extracorporeal shock wave therapy(ESWT)combined with ultrasound-guided corticosteroid injection(CSI)for the treatment of primary frozen shoulder(PFS).Methods Ninety-nine patients with PFS who visited the pain department of the Affiliated Hospital of Xuzhou Medical University between April 2024 and July 2024 were enrolled and randomly divided into three groups according to the randomized number table method:ESWT group(T group),CSI group(I group),and combined treatment group(TI group),with 33 patients in each group.Visual analogue scale(VAS)scores,shoulder range of motion(SROM),and Constant-Murley shoulder scores(CMS)were recorded before treatment and at 1,4,8,and 12 weeks post-treatment.Additionally,the patients'Ascens Insomnia Scale(AIS)scores were recorded before treatment and 1 month after treatment.The occurrence of adverse effects and the use of remedial medications during the treatment period were also documented.Results Compared with pre-treatment,VAS scores decreased,and SROM and CM scores improved at all time points after treatment in all three groups(P<0.05).AIS scores also decreased in all three groups at 1 month post-treatment(all P<0.05).Intergroup comparisons revealed that the TI group exhibited signifi-cantly lower VAS pain scores,greater SROM(forward flexion and backward extension),and higher CM scores at 4,8,and 12 weeks post-treatment compared to the T and I groups(Bonferroni-corrected P<0.05).No statistically significant differences were observed between the T and I groups for these measures(Bonferroni-corrected P>0.05).Additionally,there were no statistically significant differences in AIS scores or adverse effects occurrence among the three groups at 1 month post-treatment(P>0.05).Conclusion The combined treatment demonstrated greater efficacy compared to trigger point extracorporeal shock wave therapy alone and periapical steroid injection alone,resulting in significant improvement in the patient's clinical symptoms and quality of life.

Objective To explore the application value of CT fusion navigation technology in Stanford B-type aortic dissection endovas-cular isolation surgery.Methods Nineteen patients who underwent Stanford B-type aortic dissection endovascular isolation surgery were selected.Prior to surgery,all patients underwent chest and abdominal CT plain scan and enhanced scan,and three-dimensional vascular reconstruction was performed at the post-processing workstation;During the operation,a chest(region of interest)digital subtraction angiography(DS A)3D-CT scan was first performed as the intraoperative matching localization image.Then,a thin-layer(1.0 mm)CT enhanced tomographic image of the chest and abdomen was extracted from the picture archiving and communication system(PACS).At the same time,the DSA 3D-CT image and the thin-layer CT enhanced image were opened for overlapping regis-tration of bony landmarks.After registration,the three-dimensional vascular volume rendering(VR)image of the aorta from the thin-layer CT was fused with the DSA 3D-CT,and the positioning and release of the covered stent were guided by the newly fused multimodal real-time image.Results All 19 patients underwent guided surgery with precise positioning of the covered lesions and successful release of the covered stents,with a success rate of 100％ for the guided technique.The intraoperative placement time of the covered stent was(5.4±2.4)s,the exposure time was(12.8±3.2)min,the surgical duration was(53.9±25.3)min,the intraopera-tive contrast agent dosage was(125.8±25.3)mL,the X-ray fluoroscopy dose was(221.3±155.7)mGy,and the total X-ray exposure dose was(1 056.4±330.3)mGy.There were no serious complications during the operation,and all patients received 1-3 months of follow-up which found they all recovered well.Conclusion The use of CT and DSA fusion navigation technology in guiding the treat-ment of Stanford B-type aortic dissection with covered stents provides real-time three-dimensional fusion images for the operator,which can quickly and accurately locate and release the stent,and has certain clinical value.

Rheumatoid arthritis(RA)is an autoimmune disease characterized by chronic,aggressive joint inflammation,which seriously harms mental and physical health of patients.Efficacy of clinical drugs for RA is limited,so it is a hot issue to seek new therapeutic targets and drugs.Zinc finger protein A20,a cytoplasmic ubiquitin modifier,is closely related to negative regulation of nuclear factor-kappaB(NF-κB),an inflammatory signaling pathway,and has anti-inflammatory and anti-apoptotic effects.A20 is involved in pathogenesis of RA and can improve inflammatory response and bone destruction of RA.Treatment of RA by traditional Chinese medicine has unique advantages of multi-target and multi-pathway,and studies have found that traditional Chinese medicine has a regulatory effect on A20.This paper expounds mechanism of A20 in RA and research progress of traditional Chinese medicine intervention in A20,in order to provide references for treatment and drug development of RA.

Primary spontaneous pneumothorax (PSP) is an abnormal accumulation of gas in the pleural cavity without an underlying respiratory disease, excluding trauma or iatrogenic factors. The exact etiology and pathogenesis of PSP have not been clarified. Previous studies have confirmed that meteorological factors and environmental determinants such as atmospheric pollutant exposure can trigger the occurrence of pneumothorax, but no unified conclusion has been reached among different research results. This review summarizes the effects of meteorological factors and air pollutants on primary spontaneous pneumothorax.
