Risk prediction models for postoperative pulmonary complications (PPCs) can assist healthcare professionals in assessing the likelihood of PPCs occurring after surgery, thereby supporting rapid decision-making. This study evaluated the merits, limitations, and challenges of these models, focusing on model types, construction methods, performance, and clinical applications. The findings indicate that current risk prediction models for PPCs following lung cancer surgery demonstrate a certain level of predictive effectiveness. However, there are notable deficiencies in study design, clinical implementation, and reporting transparency. Future research should prioritize large-scale, prospective, multi-center studies that utilize multiomics approaches to ensure robust data for accurate predictions, ultimately facilitating clinical translation, adoption, and promotion.

Objective To compare the clinical efficacy of PCI with radial artery approach and bra-chial artery approach in acute myocardial infarction(AMI).Methods A retrospective analysis was performed on 173 AMI patients undergoing PCI in Department of Cardiology of Affiliated Hospi-tal of Chengde Medical College from September 2022 to September 2024.According to surgical ap-proach,they were divided into the radial artery group(97 cases)and the brachial artery group(76 cases).The X-ray exposure rate,puncture time,operation time and total hospital stay were observed in the two groups,and the puncture success rate,postoperative complication rate and incidence of 30-day cardiovascular adverse events were compared between the two groups.Results There were statistical differences in puncture time,operation duration and length of hospital stay between the two groups(P＜0.05,P＜0.01).The brachial artery group had a higher puncture success rate than the radial artery group(94.7％vs 90.7％,P=0.390),while the radial artery group had a higher incidence of postoperative complications,adverse vascular events due to coro-nary heart disease(P＜0.05,P＜0.01).Conclusion Both radial artery approach and brachial artery approach for PCI can effectively treat AMI patients.Compared with transradial approach,transbrachial approach can effectively improve the success rate of surgery,reduce postoperative complications and the occurrence of cardiovascular adverse events within 30 d of follow-up.

Objective To study the effect of the transbrachial artery approach on the success rate of puncture,revascularization time,and postprocedural complications in patients with acute ST-segment elevation myocardial infarction(STEMI)treated by percutaneous coronary intervention(PCI).Methods The clinical data of 324 patients with STEMI who underwent PCI between September 2020 and May 2024 at our hospital were retrospectively analyzed.According to the different approaches,the patients were divided into a brachial artery group(127 cases)and a radial artery group(197 cases).Their procedural parameters(X-ray exposure time,contrast agent dosage,puncture time,puncture success rate,and revascularization time)and hospital length-of-stay,cardiac function indicators,including left ventricular ejection fraction(LVEF),left ventricular fractional shortening(LVFS),left ventricular end-systolic volume index(LVESVI),and left ventricular end-diastolic volume index(LVEDVI),before surgery and 3 months after PCI,and the incidence of complications were compared between the two groups of patients.Furthermore,a difference-in-differences method was adopted for the logistic model to evaluate the effects of different approaches.Results There were no statistical differences in the general data between the brachial artery group and the radial artery group.Compared with those of the radial artery group,the revascularization time and length-of-stay of the brachial artery group were shortened,and the success rate of puncture was increased(P<0.05).There were no significant differences in X-ray exposure time or contrast agent dosage between the two groups.The changes in LVEF,LVFS,LVESVI,and LVEDVI from baseline to 3 months post-PCI were(10.97±7.15)%,(3.29±5.90)%,(22.11±9.30)mL/m2,and(18.13±6.68)mL/m2,respectively,in the brachial artery group,while those in the radial artery group were(10.61±7.13)%,(4.38±6.04)%,(23.13±9.60)mL/m2,and(19.34±7.27)mL/m2,respectively,without statistical differences.Difference-in-differences analysis revealed that there were no statistical differences in the effects of different approaches on LVEF,LVFS,LVESVI,and LVEDVI between the brachial artery group and the radial artery group.During follow-up,no complications,such as coronary perforation,coronary dissection,or stent thrombosis,were observed in either group,and there were no statistical differences in the complication incidence between the two groups.Conclusion The transbrachial artery approach can shorten the revascularization time and length-of-stay of patients with STEMI treated by PCI.It has a high success rate of puncture and can promote the recovery of postoperative cardiac function without increasing postoperative complications.

BACKGROUND:Skin wound repair is an extremely complex process.The nervous system plays an important role in regulating wound repair and scar healing.OBJECTIVE:To review the role of the nervous system in the process of skin wound repair,including the roles of related factors and various cells in the repair of skin injury.METHODS:The PubMed and CNKI databases were searched with the key words of"skin wound healing,nervous system,nerve regeneration,growth factor"in English and"skin wound healing,skin innervation,neuropeptide,growth factor,cell synergy"in Chinese.The time range of literature search was from 2003 to 2024,and 83 documents were finally included and analyzed.RESULTS AND CONCLUSION:(1)The skin is densely innervated by autonomic and sensory nerves,and there is growing evidence that the cutaneous nervous system is not only responsible for transmitting sensory information to the central nervous system,but also plays an important role in a variety of skin functions,including wound healing.(2)The nervous system acts on different stages of skin wound healing,which can regulate revascularization,promote the release of related growth factors and neurotransmitters,and cooperate with different types of cells to promote skin wound healing.Therefore,research on the underlying mechanisms of the nervous system has become a powerful target to promote skin wound healing.

Objective:To investigate the clinical efficacy of Cyclosporine A(CsA)in patients with unexplained repeated implantation failure(URIF),and to analyze the changes of peripheral blood lymphocyte subsets after CsA treatment.Methods:105 patients with URIF who underwent frozen-thawed embryo transfer(FET)in the De-partment of Reproductive Medicine in The Second Affiliated Hospital of Kunming Medical University from Septem-ber 30,2021 to March 1,2022 were selected.After informed consent,the patients were divided into CsA group(n=52)and control group(n=53)according to whether they received CsA treatment or not.Pregnancy outcomes and changes in lymphocyte subset were compared between the two groups.Results:The embryo implantation rate and clinical pregnancy rate in CsA group were higher than those in the control group,the difference was statisti-cally significant(48.91%vs.32.56%,P=0.027;53.85%vs.32.08%,P=0.024).The CsA group had a lower ear-ly abortion rate than the control group(10.71%vs.23.53%),but the difference was not statistically significant(P=0.25).The percentage of CD3-CD16+CD56+in CsA group was significantly decreased after treatment[(16.15±5.37)%vs.(18.23±7.10)%,P=0.012],it was also lower than that in the control group[(16.15±5.37)%vs.(18.67±5.16)%,P=0.018].Conclusions:CsA treatment can significantly improve the clinical preg-nancy rate and embryo implantation rate of frozen-thawed embryo transfer in patients with URIF,which may be a-chieved by promoting the distribution of peripheral blood lymphocytes to the direction of embryo implantation,es-pecially by down-regulating the percentage of CD3-CD16+CD56+.CsA has a certain application prospect in the field of assisted reproduction.
