Objective To explore the efficacy and safety of traditional Chinese medicine(TCM) combined with chemotherapy in the prevention and treatment of postoperative recurrence and metastasis of locally advanced gastric cancer (LAGC) by meta-analysis. Moreover, we evaluated the efficacy of TCM on the quality of life, immune indexes, and toxic and side effects during adjuvant chemotherapy. Methods The CNKI, Wanfang, PubMed, and other databases were searched by computer. Randomized controlled trials (RCTs) were searched. After literature screening and data extraction, Review Manager 5.3 software provided by Cochrane was used for meta-analysis. Results A total of 18 RCTs were included. Compared with chemotherapy alone, TCM combined with chemotherapy could improve the KPS score and CD3+ and CD4+/CD8+ index levels. The incidence rates of postoperative leucopenia, hemoglobin reduction, thrombocytopenia, nausea and vomiting, diarrhea, and neurotoxicity were reduced. In terms of postoperative QLQ-C30 score, abnormal liver function, and abnormal renal function, the incidence of TCM combined chemotherapy was similar to that of chemotherapy alone, with no statistical difference. Compared with chemotherapy alone, TCM combined chemotherapy could reduce the 1-, 2-, 3-, and 5-year cumulative recurrence and metastasis rates and prolong the disease-free survival time. Conclusion Compared with chemotherapy alone in adjuvant chemotherapy, TCM combined chemotherapy could improve the immune level and KPS score of LACC patients after surgery, reduce the incidence of adverse reactions, as well as reduce the recurrence and metastasis rate of LAGC after surgery and DFS could be improved.

Background: Depression post-myocardial infarction (MI) is becoming more prevalent. The gut-brain axis (GBA), influenced by the gut microbiota, is a critical component in understanding depression post-MI. Despite the well-established connection between gut microbiota and depression post-MI, this relationship remains incompletely understood. Methods and analysis: This protocol will follow the Preferred Reporting Items for Systematic Review and Meta-analysis Protocol (PRISMA-P) 2020 statement. Beginning from inception to October 2023, a systematic search will be conducted across eight electronic databases, including PubMed, MEDLINE, Scopus, Embase, Cochrane Clinical Trials Database, Web of Science, China National Knowledge Infrastructure, and China Biomedical Literature Database. Pre-selected studies will be independently assessed by two researchers following a standard inclusion, data extraction and quality assessment protocol. The primary outcome measures are differences in the profile of gut microbiota and rating scale scores for depression. Fixed-effects models will be used when both clinical heterogeneity and statistical heterogeneity are low, otherwise random-effects models will be used. Furthermore, subgroup analyses will be conducted on the depression severity of the participants using the same psychiatric scales employed, study type and geographic region. Random forest plot runs and research-related statistical analyses will be carried out using Rev Man V.5.3 software. Expected results: This study will identify the association between the gut microbiota and the onset of depression post-MI, and provide evidence for the use of probiotics as an adjunctive treatment for depression post-MI. Trial registration: Prospero registration number:CRD42023444026. [ABSTRACT FROM AUTHOR]

In this paper, an optimal scheduling method based on building virtual energy storage equivalent battery is proposed. Firstly, the thermal load prediction model is built based on the thermodynamic model, and then the equivalent battery model of virtual energy storage is established by combining with inverter air conditioning system model. Then, with the goal of minimizing the user’s electricity cost, considering the constraints of energy storage state and charging and discharging power of equivalent battery model, an optimal scheduling method of building virtual energy storage equivalent battery is constructed. The results show that the proposed method can predict the building thermal load, update the building virtual energy storage equivalent battery parameters, formulate the corresponding optimal scheduling strategy, and reduce the electricity cost of users for heating on the premise of ensuring the thermal comfort of users.

Polyacrylonitrile (PAN) fibers were heated and stretched in a steam bath mixed with nitrogen in the early stage of stabilization. During this process, the flexible linear chain of PAN molecule was converted to a rigid ladder structure by intramolecular cyclization. The shrinkage tension along the fiber axis decreased during this heat treatment, because water molecules here acted as a plasticizer for stretching. Consequently, the preferred orientation of ladder molecules in the stabilized fibers was enhanced. As a result, the preferred orientation, crystallite dimensions, and mechanical properties of the resultant carbon fibers (CFs) and graphite fibers (GFs) were improved, comparing with the corresponding CFs and GFs without pretreatment in the steam bath. POLYM. ENG. SCI., 53:827-832, 2013. © 2012 Society of Plastics Engineers, INTRODUCTION The preferred orientation of crystallites along the fiber axis is one of the most important structure parameters for carbon fibers (CFs). Higher preferred orientation usually gives rise to higher [...]

Background: Triglyceride-glucose (TyG) index is a surrogate marker of insulin resistance and metabolic abnormalities, which is closely related to the prognosis of a variety of diseases. Patients with both CHD and depression have a higher risk of major adverse cardiovascular and cerebrovascular events (MACCE) and worse outcome. TyG index may be able to predict the adverse prognosis of this special population., Methods: The retrospective cohort study involved 596 patients with both CHD and depression between June 2013 and December 2023. The primary outcome endpoint was the occurrence of MACCE, including all-cause death, stroke, MI and emergent coronary revascularization. The receiver operating characteristic (ROC) curve, Cox regression analysis, Kaplan-Meier survival analysis, and restricted cubic spline (RCS) analysis were used to assess the correlation between TyG index and MACCE risk of in patients with CHD complicated with depression., Results: With a median follow-up of 31 (15-62) months, MACCE occurred in 281(47.15%) patients. The area under the ROC curve of TyG index predicting the risk of MACCE was 0.765(0.726-0.804) ( P <0.01). Patients in the high TyG index group(69.73%) had a significantly higher risk of developing MACCE than those in the low TyG index group(23.63%) ( P <0.01). The multifactorial RCS model showed a nonlinear correlation (nonlinear P <0.01, overall P <0.01), with a critical value of 8.80 for the TyG index to predict the occurrence of MACCE. The TyG index was able to further improve the predictive accuracy of MACCE., Conclusions: TyG index is a potential predictor of the risk of MACCE in patients with CHD complicated with depression., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Zhao, Wang, Chen, Ding, Hou, Gui, Liu, Li, Liu, Sun and Zhao.)
