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.

ObjectiveBased on the concept of quality by design(QbD), the processing process of calcined Pyritum was optimized, and its X-ray diffraction(XRD) fingerprint was established. MethodsThe safety, effectiveness and quality controllability of calcined Pyritum were taken as the quality profile(QTPP), the color, hardness, metallic luster, phase composition, the contents of heavy metals and hazardous elements were taken as the critical quality attributes(CQAs), and the calcination temperature, calcination time, paving thickness and particle size were determined as the critical process parameters(CPPs). Differential thermal analysis, X-ray diffraction(XRD) and inductively coupled plasma mass spectrometry(ICP-MS) were used to analyze the correlation between the calcination temperature and CQAs of calcined Pyritum. Then, based on the criteria importance through intercriteria correlation(CRITIC)-entropy weight method, the optimal processing process of calcined Pyritum was optimized by orthogonal test. Powder XRD was used to analyze the phase of calcined Pyritum samples processed according to the best process, and the mean and median maps of calcined Pyritum were established by the superposition of geometric topological figures, and similarity evaluation and cluster analysis were carried out. ResultsThe results of single factor experiments showed that the physical phase of Pyritum changed from FeS2 to Fe7S8 during the process of temperature increase, the color gradually deepened from dark yellow, and the contents of heavy metals and harmful elements decreased. The optimized processing process of calcined Pyritum was as follows:calcination temperature at 750 ℃, calcination time of 2.5 h, paving thickness of 3 cm, particle size of 0.8-1.2 cm, vinegar quenching 1 time[Pyritum-vinegar(10∶3)]. After calcination, the internal structure of Pyritum was honeycomb-shaped, which was conducive to the dissolution of active ingredients. XRD fingerprints of 13 batches of calcined Pyritum characterized by 10 common peaks were established. The similarities of the relative peak intensities of the XRD fingerprints of the analyzed samples were>0.96, and it could effectively distinguish the raw products and unqualified products. ConclusionTemperature is the main factor affecting the quality of calcined Pyritum. After processing, the dissolution of the effective components in Pyritum increases, and the contents of heavy metals and harmful substances decrease, reflecting the function of processing to increase efficiency and reduce toxicity. The optimized processing process is stable and feasible, and the established XRD fingerprint can be used as one of the quality control standards of calcined Pyritum.

PURPOSE:
The rate of complications among patients undergoing surgery has increased due to infection with SARS-CoV-2 and other variants of concern. However, Omicron has shown decreased pathogenicity, raising questions about the risk of postoperative complications among patients who are infected with this variant. This study aimed to investigate complications and related factors among patients with recent Omicron infection prior to undergoing orthopedic surgery.
METHODS:
A historical control study was conducted. Data were collected from all patients who underwent surgery during 2 distinct periods: (1) between Dec 12, 2022 and Jan 31, 2023 (COVID-19 positive group), (2) between Dec 12, 2021 and Jan 31, 2022 (COVID-19 negative control group). The patients were at least 18 years old. Patients who received conservative treatment after admission or had high-risk diseases or special circumstances (use of anticoagulants before surgery) were excluded from the study. The study outcomes were the total complication rate and related factors. Binary logistic regression analysis was used to identify related factors, and odds ratio (OR) and 95% confidence interval (CI) were calculated to assess the impact of COVID-19 infection on complications.
RESULTS:
In the analysis, a total of 847 patients who underwent surgery were included, with 275 of these patients testing positive for COVID-19 and 572 testing negative. The COVID-19-positive group had a significantly higher rate of total complications (11.27%) than the control group (4.90%, p < 0.001). After adjusting for relevant factors, the OR was 3.08 (95% CI: 1.45-6.53). Patients who were diagnosed with COVID-19 at 3-4 weeks (OR = 0.20 (95% CI: 0.06-0.59), p = 0.005), 5-6 weeks (OR = 0.16 (95% CI: 0.04-0.59), p = 0.010), or ≥7 weeks (OR = 0.26 (95% CI: 0.06-1.02), p = 0.069) prior to surgery had a lower risk of complications than those who were diagnosed at 0-2 weeks prior to surgery. Seven factors (age, indications for surgery, time of operation, time of COVID-19 diagnosis prior to surgery, C-reactive protein levels, alanine transaminase levels, and aspartate aminotransferase levels) were found to be associated with complications; thus, these factors were used to create a nomogram.
CONCLUSION
Omicron continues to be a significant factor in the incidence of postoperative complications among patients undergoing orthopedic surgery. By identifying the factors associated with these complications, we can determine the optimal surgical timing, provide more accurate prognostic information, and offer appropriate consultation for orthopedic surgery patients who have been infected with Omicron.

Objective To evaluate the efficacy and safety of concurrent chemoradiotherapy versus sequential chemoradiotherapy in the treatment of locally advanced non-small cell lung cancer. Methods The relevant literature was searched in PubMed, Web of Science, CNKI and Wanfang databases from the inception to October 15, 2023, and the literature was screened according to the inclusion and exclusion criteria. Review Manager 5.3 software was used for meta-analysis of the literature, and the Cochrane bias risk assessment tool was used to evaluate the quality of the literature. Results Finally, 14 randomized controlled studies were included covering a total of 1048 patients. The results of meta-analysis showed that the overall response rate [OR=2.39, 95%CI (1.83, 3.11)], 1-year survival rate [OR=1.81, 95%CI (1.39, 2.35)], 2-year survival rate [OR=1.75, 95%CI (1.27, 2.42)] and 3-year survival rate [OR=2.33, 95%CI (1.49, 3.66)] were superior to sequential chemoradiotherapy (P<0.001). In terms of safety, concurrent chemoradiotherapy increased the incidence of radiation esophagitis (P<0.05), but there was no statistical difference in the incidence of leukopenia and radiation pneumonia (P>0.05). Conclusion For patients with locally advanced non-small cell lung cancer, the short-term efficacy of concurrent chemoradiotherapy is better than that of sequential chemoradiotherapy and can improve the 1-, 2- and 3-year survival rates, but the toxic side effects of the treatment are slightly greater than those of the sequential chemoradiotherapy.

BackgroundAs a high prevalence disorder, schizophrenia has caused significant burden to family and society due to the impairment of occupational and social function. Currently, the dominant vocational training model in China follows a paternalistic, clinician-led decision-making approach. Although it improves patients' social function to some extent, it undermines their autonomy and treatment adherence. Therefore, it is urgently necessary to explore a new intervention method to enhance treatment compliance and social function in patients. ObjectiveTo explore the impact of shared decision-making oriented vocational training on social function in hospitalized schizophrenia patients, so as to provide references for rehabilitation interventions. MethodsA total of 68 patients diagnosed with schizophrenia according to the International Classification of Diseases, tenth edition (ICD-10) criteria were consecutively enrolled from January to June 2024 at The Third People's Hospital of Wenjiang Distric, Chengdu. Participants were randomly allocated into the research group (n=34) and the control group (n=34) using a random number table method. Both groups received routine rehabilitation training, while the research group received shared decision-making oriented vocational training for 12 weeks, 2 times a week for 2 hours each time. Before and at the 4th and 12th week of intervention, two groups were evaluated by General Self-Efficacy Scale (GSES), Stigma Scale for Mental Illness (SSMI), Scale of Social function of Psychosis Inpatients (SSFPI) and Inpatient Psychiatric Rehabilitation Outcome Scale (IPROS). ResultsA total of 63 participants completed the study, with 30 cases in the research group and 33 cases in the control group. Repeated measures ANOVA revealed statistically significant time effects and interaction effects in both groups for GSES, SSMI, SSFPI and IPROS scores (F=20.451, 16.022; 26.193, 12.944; 23.957, 5.023; 11.776, 3.985, P<0.05 or 0.01), while no significant group effects were observed (F=0.188, 0.742, 1.878, 0.474, P>0.05). At the 12th week of intervention, there were statistically significant differences in GSES, SSMI, SSFPI and IPROS scores between the two groups. ConclusionShared decision-making oriented vocational training may help to improve social function in patients with schizophrenia. [Funded by 2023 Chengdu Medical Research Project (number, 2023468)]
