The plasma membrane (PM) plays an essential role in maintaining cell homeostasis, therefore, timely and effective repair of damage caused by factors such as mechanical rupture, pore-forming toxins, or pore-forming proteins is crucial for cell survival. PM damage induces membrane rupture and stimulates an immune response. However, damage resulting from regulated cell death processes, including pyroptosis, ferroptosis, and necroptosis, cannot be repaired by simple sealing mechanisms and thus, requires specialized repair machinery. Recent research has identified a PM repair mechanism of regulated cell death-related injury, mediated by the endosomal sorting complexes required for transport (ESCRT) machinery. Here, we review recent progress in elucidating the ESCRT machinery-mediated repair mechanism of PM injury, with particular focus on processes related to regulated cell death. This overview, along with continued research in this field, may provide novel insights into therapeutic targets for diseases associated with dysregulation of regulated cell death pathways.

In recent years, a number of highly active antitumor candidates have been discovered with a significant progress. This article reviews the research progress of evodiamine-based antitumor drug design strategies, in order to provide reference for the development of new drugs with natural products as leads.

Objective:To summarize the clinical characteristics and first aid measures of children with drowning，and to provide scientific basis for the treatment and prevention of drowning in children.Methods:The clinical data of drowning children admitted to the Children's Medical Center of the First Affiliated Hospital of Hunan Normal University（Hunan Provincial People's Hospital）from January 2011 to December 2021 were retrospectively summarized. Baseline characteristics，prehospital emergency care and prognosis of the included children were analyzed.According to the time span, drowning children were divided into two stages, the first stage (2011-2016) and the second stage (2017-2021). According to cerebral performance category assessment scale,drowning children with cardiac arrest were divided into two groups: a group with good neurological prognosis and a group with poor neurological prognosis. The baseline characteristics,pre-hospital emergency care, and prognosis of drowning children during different periods and with different prognosis were analyzed.Results:A total of 53 children were enrolled during the study period，with 24 cases in the first phase（2011-2016）and 29 cases in the second phase（2017-2021）.Boys accounted for 73.6%（39/53）of the cases, the age ranged from 1 month and 24 days to 14 years old，with 1-4 years old being the most common，accounting for 58.5%（31/53）, and the season in which drowning occurred was more common in the summer（39.6%, 21/53）.Six cases (11.3%) had significant neurological sequelae, and the mortality rate was 3.8%（2/53）.There was a decrease in the proportion of drowning with water control in the second stage compared to the first stage（37.5% vs. 13.79%, P=0.046）.Thirty-two（60.4%）children experienced on-site cardiopulmonary resuscitation(CPR) after drowning，with 24 cases in the group with good neurological prognosis and 8 cases in the group with poor neurological prognosis.Children in the poor neurological prognosis group required CPR for a long duration [10.00（1.50, 25.00）min]，had lower body temperature，Glasgow Coma Score，pH and higher blood glucose levels on admission（all P < 0.05）. Conclusion:Drowning is most common in preschool children，common in boys，and drowning prevention measures for young children deserve focused attention. Children found to be in cardiac arrest at the time of drowning have a long duration of drowning and CPR，which predicts a poor neurological prognosis，and timely and effective on-site CPR is the key to reducing the drowning rate.

With the aging and changes in living conditions,the incidence rate and mortality of tumors have been rising rapidly,which has become a hot topic in the medical field.At present,the treatment methods or tumors are also improving day by day,mainly relying on surgical resection.However,the characteristics of fast tumor metastasis and spread,as well as complex growth locations,make the surgical resection method limited.More and more people choose drug targeted therapy for tumors in order to reduce surgical side effects,among which cyclic guanosine monophosphate synthase interferon gene stimulatory factor(cGAS-STING signaling pathway)plays an important role in the occurrence,proliferation,and survival of tumor cells.At present,there are many types of drugs used to treat tumors,but most of them have limited control over tumor spread.In order to study the role of traditional Chinese medicine in tumor treatment and leverage its multi-component,multi target,and multi pathway characteristics,this article comprehensively analyzes and summarizes the treatment of tumors using traditional Chinese medicine based on the cGAS-STING signaling pathway in recent years,in order to further study the mechanism of action of traditional Chinese medicine and its active ingredients in the cGAS-STING signaling pathway,it also provides ideas for clinical research on new drugs.

Objective:To investigate the clinical effect of jujube core-shaped tissue resection technique in the treatment of alar reduction.Methods:A retrospective analysis was performed for the clinical data of patients who underwent alar reduction from February 2019 to June 2022. A spindle-shaped incision line was designed along the outer edge of the base of the nasal lobule, with a width of 4-5 mm and a length of 8-12 mm. The incision line was 1-2 mm away from the alar groove, and the inner side of the design line was extended to the inside of the nasal vestibule. After the incision was made, the subcutaneous tissue was undermining dissected with curved sharp scissors, and the shape of the extended excision tissue was similar to that of jujube core. After reduction, the incision was closed with vertical mattress suture. The surgical effect and complications were followed up after surgery, and an independent attending plastic surgeon evaluated the outcome and scarring based on photos before and at the last postoperative follow-up using the global aesthetic improvement scale (GAIS) and the Vancouver scar scale (VSS). GAIS is graded as 1, 2, 3, 4, and 5 points, and the lower the score, the better the improvement(&le;3 points as effective improvement). VSS includes four parameters: color (0-3 points), thickness (0-4 points), vascular distribution (0-3 points), and softness (0-5 points). The higher the score, the more significant the scar is.Results:A total of 20 patients were enrolled, including 6 males and 14 females, aged 20 to 33 years, with an average age of 24.9 years. Before the operation, there were different degrees of alar flare and alar hypertrophy. After surgery, 13 patients had mild swelling, ecchymosis, which resolved after 3 days. There were no major complications as infection, incision dehiscence, and delayed healing. After 3 to 16 months of postoperative follow-up, 2 patients gradually developed cartilage deformation and affected the appearance of the nostrils 6 to 9 months after surgery due to the combination of rib-based rhinoplasty, and the satisfactory results were obtained after revision surgery. The symmetry of the nostrils was significantly improved. The GAIS score of 20 patients was (1.20±0.41) points, of which, 16 patients were rated as 1 point and 4 patients were rated as 2 points, all of which met the improvement criteria, and the VSS score was (1.45±0.60) points, in which the average score for color, thickness, vasculature and compliance are 0.60, 0.05, 0.55 and 0.30 points respectively.Conclusion:The application of jujube core-shaped tissue resection technique for alar reduction can increase the amount of tissue removal with the same incision width, which can not only fully narrow the alar effectively but also correct the hypertrophy of the alar tissue.

Objective To observe the safety and efficacy of perioperative short-duration platelet membrane glycoprotein Ⅱ b/Ⅲ a receptor antagonist(GPI)in elderly patients undergoing primary percutaneous coronary intervention(PPCI)for acute ST-segment elevation myocardial infarction(STEMI)with high thrombotic burden.Methods A total of 140 elderly patients with acute STEMI admitted to our department from October 2021 to January 2024 were recruited and ran-domly divided into experimental group(short duration)and control group(standard duration),with 70 cases in each group.The occurrence of MACE,complete rate of ST segment resolution 2 h after surgery,blood flow classification thrombolysis in myocardial infarction(TIMI),left ventric-ular ejection fraction(LVEF),N-terminal pro-B-type natriuretic peptide(NT-proBNP),inhibition of platelet aggregation(IPA)by thromboelastography(TEG),maximum amplitude of adenosine diphosphate receptor pathway(MAADP),platelet-related indicators,and incidences of thrombocy-topenia and bleeding events were observed in the 2 groups after operation.Results There were no significant differences in postoperative recurrence of angina pectoris,acute heart failure,malignant arrhythmia,rate of ST segment resolution,TIMI blood flow grade 3,no reflow,LVEF,NT-proBNP level before discharge,and incidences of severe hemorrhage and thrombocytopenia during hospi-talization between the two groups(P＞0.05).The experimental group had significantly lower IPA[(76.1±15.3)％vs(96.3+19.4)％,P=0.016]and higher MAADP(45.6±8.2 mm vs 26.7±9.7 mm,P=0.028)in 18 h after operation,and lower incidence of minor bleeding(7.1％vs 24.3％,P＜0.05)during hospitalization when compared with the control group.Conclusion Under the premise of using a novel oral purinergic receptor P2Y12 inhibitor,short-term GPI is not inferior to the standard time course in achievement of IPA,with similar efficacy and relatively better safety.

Objective:To understand the epidemiological characteristics of human parainfluenza viruses（HPIVs）infections in patients with acute lower respiratory tract infection（ALRTI）in Changsha，Hunan from 2013 to 2023.Methods:The respiratory virus detection results,demographic characteristics and clinical data of children hospitalized with ALRTI in Children's Medical Center of Hunan Provincial People's Hospital (the First Affiliated Hospital of Hunan Normal University) from January 2013 to December 2023 were retrospectively collected.The epidemic characteristics and clinical symptoms of HPIVs infection were analyzed.Results:During the study,59 725 children with ALRTI were included,the detection rate of HPIVs was 6.66% (3 978/59 725),among which,HPIV1,HPIV2,HPIV3 were detected in 753(1.26%) cases,217(0.36%) cases and 3 055(5.12%) cases,respectively.Among 3 978 cases infected with HPIVs,the overall detection rate in males was higher than that in females(6.99% vs. 6.14%),and the detection rate of HPIVs in 6-11 months old was higher than those in other age groups,with statistically significant differences( P<0.001).Among cases infected with HPIVs,the main clinical diagnosis were mild pneumonia (77.28%) and acute bronchiolitis (14.40%).The detection rate of HPIV3 was the highest (84.62%) in 208 HPIVs-positive children with severe pneumonia,and the difference was statistically significant ( P<0.001).The detection rate of HPIVs varied across different years,reaching its peak in 2020 with a detection rate of 13.99% ( P<0.001).The overall epidemic peak of HPIVs was in spring and summer.The seasonal epidemic characteristics in different types of HPIVs were not completely consistent.The detection rates of HPIV1(2.07%) and HPIV2(0.60%) were the highest in autumn,while that of HPIV3 (7.11%) was the highest in spring ( P<0.001).The seasonal epidemic characteristics of HPIVs have changed in different years:From 2013 to 2019,HPIVs was mainly prevalent in spring and summer,then shifted to summer and autumn in 2020,and autumn as well as winter in 2021 to 2022,then resumed in spring and summer in 2023. Conclusion:From 2013 to 2023,HPIVs in Changsha,Hunan Province had unique epidemiological characteristics.HPIV3 is the dominant type of HPIVs infection in the hospitalized children with ALRTI in Changsha，Hunan.The epidemic peak of HPIVs was postponed in 2020 to 2022.Paying attention to the continuous monitoring of HPIVs infection is helpful to guide clinicians' diagnosis and treatment.

Objective Evaluation of the clinical efficacy of f trochanteric flip osteotomy combined with Kocher-Langen-beck approach for high acetabular posterior wall fracture.Methods Between January 2020 and December 2022,20 patients with high acetabular posterior wall fractures were retrospectively analyzed,including 12 males and 8 females,aged 18 to 75 years old.They were divided into two groups according to the different surgical methods.Ten patients were treated with greater trochanteric osteotomy combined with Kocher-Langenbeck approach as the observation group,including 5 males and 5 fe-males,aged from 18 to 75 years old.Ten patients were treated with Kocher-Langenbeck approach alone as the control group,including 7 males and 3 females,aged from 18 to 71 years old.Matta reduction criteria were used to evaluate the reduction quality of the two groups,and Harris score was used to compare the hip function of the two groups at the latest follow-up.The operation time,blood loss and postoperative complications of the two groups were analyzed.Results All patients were followed up for 10 to 24 months.According to the Matta fracture reduction quality evaluation criteria,the observation group achieved anatomical reduction in 6 cases,satisfactory reduction in 3 cases,and unsatisfactory reduction in 1 case,while the control group only achieved anatomical reduction in 3 cases,satisfactory reduction in 3 cases,and unsatisfactory reduction in 4 cases.At the final follow-up,the Harris hip score ranged from 71.4 to 96.6 in the observation group and 65.3 to 94.5 in the control group.According to the results of Harris score.The hip joint function of the observation group was excellent in 6 cases,good in 3 cases,and fair in 1 case.The hip joint function of the control group was excellent in 2 cases,good in 3 cases,fair in 3 cases,and poor in 2 cases.In the observation group,the intraoperative blood loss ranged from 300 to 700 ml,and the operation dura-tion ranged from 120 to 180 min;in the control group,the intraoperative blood loss ranged from 300 to 650 ml,and the opera-tion duration ranged from 100 to 180 min.Complications in the observation group included 1 case of traumatic arthritis and 1 case of heterotopic ossification,while complications in the control group included 3 cases of traumatic arthritis,3 cases of het-erotopic ossification and 1 case of hip abduction weakness.Conclusions Trochanteric flip osteotomy combined with the Kocher-Langenbeck approach significantly improved anatomical fracture reduction rates,enhanced excellent and good hip joint function outcomes,and reduced surgical complication incidence compared to the Kocher-Langenbeck approach alone.Clinical application of this combined approach is promising,although larger studies are needed for further validation.

  Objective  To identify the risk factors for postoperative nausea and vomiting (PONV) in surgical patients undergoing patient controlled intravenous analgesia (PCIA).  Methods  Our study was a retrospective cohort study, including patients who underwent surgery at Peking Union Medical College Hospital from July 1 to October 31, 2023 and received PCIA after surgery. Patient characteristics, medical history, surgical information, intraoperative medication information, postoperative analgesia follow-up information were obtained through the electronic medical record system. The patients were divided into PCIA-PONV group and non-PCIA-PONV group, depending on the occurrence of PONV during PCIA, and all patients were also divided into PCIA-POV group and non-PCIA-POV according to whether postoperative vomiting (POV) occurred. Multivariate Logistic regression analysis was used to identify the risk factors for PCIA-PONV and PCIA-POV.  Results  A total of 1373 patients were included in this study, with 676 cases in PCIA-PONV group. The incidence of PCIA-PONV was 49.2%. There were 285 patients in PCIA-POV group, and the incidence of PCIA-POV was 20.8%. The results of multivariate Logistic regression analysis showed that female (OR=2.134, 95% CI: 1.590-2.865, P < 0.001) and abdominal surgery (OR=1.655, 95% CI: 1.253-2.186, P < 0.001) were risk factors for PCIA-PONV, whereas the increase of age (OR=0.990, 95% CI: 0.982-0.998, P=0.019) and the increase of BMI (OR=0.961, 95% CI: 0.932-0.991, P=0.012) were protective factors for PCIA-PONV. Female (OR=2.646, 95% CI: 1.754-3.992, P < 0.001), history of general anesthesia (OR=1.372, 95% CI: 1.042-1.806, P=0.024), and intraoperative use of high-dose opioids (OR=1.607, 95% CI: 1.206-2.142, P=0.001) were risk factors for PCIA-POV, whereas no intraoperative use of neuromuscular blocking antagonists (OR=0.393, 95% CI: 0.237-0.651, P < 0.001) was protective factor for PCIA-POV.  Conclusions  Our study reveals the risk factors for PONV in surgical patients undergoing PCIA, and shows that comprehensive preoperative assessment and reasonable perioperative management strategies are significant in the prevention of PCIA-PONV.
