MethodsAccording to the systematic review of text and opinion （SrTO） process developed by the Joanna Briggs Institute （JBI） in Australia， this paper determined literature screening criteria by searching China National Knowledge Infrastructure （CNKI）， VIP， Wanfang， and China Biomedical Literature Database. Information was extracted after literature screening， and quality evaluation was conducted using the JBI Narrative， Text， and Opinion Systematic Review Strict Evaluation Checklist. The JBI Narrative， Opinion， Text Evaluation， and Review Tool Summary Table was used for information synthesis， and data analysis and display were conducted in the form of text and charts. ResultsThe 146 articles related to 39 renowned experts and 19 articles related to 10 schools of thought were included. Research has found that contemporary experts and schools in traditional Chinese medicine gynecology consider blood stasis as the core pathogenesis in understanding the etiology and pathogenesis of two diseases and related infertility. Their viewpoints varied from multiple aspects such as clinical symptom characteristics， meridian circulation location， pathological product evolution， disease duration， emotional psychology， lifestyle habits， preference for food and drink， innate endowment， and acquired injury. In terms of treatment， it was advocated to divide the stage， treat according to different types， adapt to the times， integrate nature and humans， and combine multiple methods to treat comprehensively when necessary. It was also recommended to skillfully use insects， make good use of classic formulas and small prescriptions， pay attention to protecting the spleen and stomach and regulating emotions， and make good use of self-formulated empirical formulas for internal or external use. Besides， individualized long-term management of patients was also advocated. ConclusionThis study applies the SrTO process to systematically summarize the academic ideas of contemporary renowned experts and schools in traditional Chinese medicine gynecology regarding the causes， mechanisms， diagnosis， and treatments of endometriosis， providing a scientific and standardized reference for future theoretical exploration.

Reactive astrocytes, which exhibit a correlation with the degeneration of dopaminergic neurons, are present in a considerable number during the progression of Parkinson's disease (PD). However, the underlying factors shaping astrocyte reactivity and neuroinflammation in PD remain inadequately elucidated. Here, we demonstrate that fibroblast growth factor 7 (FGF7)/FGF receptor 2 (FGFR2) autocrine signaling intensifies astrocyte reactivity and inflammation. Genetic deletion of Arrb2, β-Arrestin2 encoding gene, led to escalated astrocyte reactivity in MPTP-treated mice, which was further substantiated in astrocyte-specific Arrb2 knockdown mice. RNA sequencing profiling of Arrb2 knockout astrocytes identified Fgf7 as a critical effector of astrocyte reactivity. Subsequently, conditional knockdown of Fgf7 and its receptor Fgfr2 in astrocytes elicited advantageous effects for MPTP-treated mice by restraining the inflammatory phenotypic transition of reactive astrocytes. Furthermore, deletion of astrocytic Fgf7 mitigated MPTP-induced pathology in Arrb2 knockout mice. Mechanistically, STAT1 was distinguished as the transcription factor suppressing Fgf7 expression, while β-Arrestin2 counteracted the proteasomal degradation of STAT1 by binding to RNF220, an E3 ubiquitin ligase for STAT1. More importantly, selectively engaging dopamine D2 receptor (Drd2)/β-Arrestin2-biased signaling using the agonist UNC9995 exhibited therapeutic potential in MPTP-treated mice via moderation of astrocytic FGF7 production, thereby restoring balance in astrocyte reactivity. Collectively, our study bridges a crucial knowledge gap by elucidating the novel functions of FGF family members within the central nervous system, particularly within the context of PD. The autocrine signaling of FGF7/FGFR2 represents a novel mechanism and a potential druggable target for modulating astrocyte-derived inflammation.

Cancer multidrug resistance (MDR) impairs the therapeutic efficacy of various chemotherapeutics. Novel approaches, particularly the development of MDR reversal agents, are critically needed to address this challenge. This study demonstrates that tenacissoside I (TI), a compound isolated from Marsdenia tenacissima (Roxb.) Wight et Arn, traditionally used in clinical practice as an ethnic medicine for cancer treatment, exhibits significant MDR reversal effects in ABCB1-mediated MDR cancer cells. TI reversed the resistance of SW620/AD300 and KBV200 cells to doxorubicin (DOX) and paclitaxel (PAC) by downregulating ABCB1 expression and reducing ABCB1 drug transport function. Mechanistically, protein arginine methyltransferase 1 (PRMT1), whose expression correlates with poor prognosis and shows positive association with both ABCB1 and EGFR expressions in tumor tissues, was differentially expressed in TI-treated SW620/AD300 cells. SW620/AD300 and KBV200 cells exhibited elevated levels of EGFR asymmetric dimethylarginine (aDMA) and enhanced PRMT1-EGFR interaction compared to their parental cells. Moreover, TI-induced PRMT1 downregulation impaired PRMT1-mediated aDMA of EGFR, PRMT1-EGFR interaction, and EGFR downstream signaling in SW620/AD300 and KBV200 cells. These effects were significantly reversed by PRMT1 overexpression. Additionally, TI demonstrated resistance reversal to PAC in xenograft models without detectable toxicities. This study establishes TI's MDR reversal effect in ABCB1-mediated MDR human cancer cells through inhibition of PRMT1-mediated aDMA of EGFR, suggesting TI's potential as an MDR modulator for improving chemotherapy outcomes.

Objective: To investigate the effects of usnic acid(UA) on proliferation, cell cycle, apoptosis and autophagy of lung cancer cells A549 and NCI-H358. Methods: The CCK-8 method was used to detect the inhibitory effect of UA on two kinds of lung cancer cells proliferation. Flow cytometry was used to detect the cell cycle arrest effect of UA on two types of lung cancer cells. The fluorescence amount of UA-induced reactive oxygen species(ROS) in two kinds of lung cancer cells were detected by DCFH-DA probe assay and flow cytometry. Western blot was used to detect the expression of apoptosis related proteins Bax, Caspase-3, Cleaved-Caspase-3, and autophagy related proteins LC3-Ⅰ and LC3-Ⅱ in two types of lung cancer cells after treatment with UA and UA+ROS inhibition. Results: (1) Usnic acid reduced the survival rates of two types of cells and had a stronger ability to inhibit the proliferation of A549 cells than NCI-H358 cells.(2) Usnic acid blocked A549 cells in the G0/G1phase, while NCI-H358 cells in the G2/M and S phases.(3) Usnic acid induced an increase in ROS content in two types of cells. Compared to A549, NCI-H358 cells showed a greater increase in ROS, and the ROS inhibitor reduced the intracellular ROS increase induced by UA.(4) Usnic acid induced high expression of apoptosis-related proteins Bax and Cleaved Caspase-3 and increased the ratio of autophagy-related proteins LC3-Ⅱ/LC3-Ⅰ in both lung adenocarcinoma cells, and its pro-apoptotic and autophagic effects were stronger in A549 than in NCI-H358. After ROS inhibition, the expression levels of Bax and Cleaved Caspase-3 and the LC3-Ⅱ/LC3-Ⅰ ratio of both lung adenocarcinoma cells decreased, and the decrease was greater in NCI-H358 cells. Conclusion Usnic acid inhibits the proliferation of lung cancer A549 and NCI-H358 cells, induces cell cycle arrest, and induces apoptosis and autophagy in cancer cells. The inhibitory and killing effect of UA on A549 cells is stronger than that on NCI-H358 cells. In this case, the induced cell ROS are involved in the action of UA in two types of lung cancer cells. In contrast to A549 cells,ROS might play a more significant role in mediating the apoptosis and autophagy induced by usnic acid in NCI-H358 cells.

Objective To investigate the diagnostic value of serum levels of leukocyte cell derived chemo-taxin 2(LECT2)and tumor necrosis factor ligand-related molecule-1A(TL1A)in children with atopic der-matitis(AD).Methods A total of 83 children with AD who were adimitted to the hospital from August 2021 to August 2023 were selected as the AD group,and 83 healthy children who underwent physical examination in the hospital during the same period were selected as the control group.Enzyme linked immunosorbent assay(ELISA)was applied to measure the expression levels of LECT2 and TL1A in serum.Spearman method was applied to analyze the correlation between serum LECT2,TL1A,and AD integral index(SCORAD).Multiva-riate Logistic regression was applied to analyze the factors that affected the severity of AD in children.Receiv-er operating characteristic(ROC)curve was applied to analyze the diagnostic efficacy of serum LECT2 and TL1A levels on the severity of AD in children.Results Compared with the control group,the expression lev-els of LECT2 and TL1A in the serum of the AD group were significantly increased(P＜0.05).Compared with the low-grade group,the serum LECT2,TL1 A,SCORAD score,EOS and total IgE in the moderate and severe groups were significantly increased in turn(P＜0.05).According to Spearman correlation analysis,the serum levels of LECT2 and TL1A in the AD group were positively correlated with the SCORAD score(r=0.776,0.693,both P＜0.05).According to the results of multivariate Logistic regression analysis,serum LECT2、TL1 A、EOS and total IgE were risk factors affecting the severity of AD in children(P＜0.05).In ad-dition,the combination of serum LECT2 and TL1A had the highest AUC for diagnosing the severity of AD in children,which was better than the individual diagnosis of serum LECT2 and TL1A(Z=2.249,1.989,P=0.025,0.047).Conclusion The elevated levels of serum LECT2 and TL1A in children with AD are closely re-lated to the severity of the disease,and the combination of the two can better evaluate the severity of the dis-ease in children with AD.

Objective:To investigate the clinicopathological features and molecular characteristics of β-catenin-deficient colorectal cancer.Methods:The clinical, pathological and molecular features of 11 colorectal cancers with β-catenin protein loss diagnosed at the 960th Hospital of People′s Liberation Army of China, from January 2012 to November 2022 were analyzed.Results:Among the 11 patients, 3 were males and 8 were females. Their age ranged from 43 to 74 years, with the median age of 59 years. Six were in the left colon and 5 were in the right colon. One of the 11 cases had lymph node metastasis, 10 cases were well and moderately differentiated adenocarcinoma, and 1 was mucinous adenocarcinoma. Eight cases were of TNM stage T4, 2 of T1 stage and 1 of Tis stage. β-catenin protein was not detected using immunohistochemistry. Sanger sequencing revealed the presence of fragment-deletion mutation in exon 3 of CTNNB1 gene, resulting in loss of β-catenin protein expression.Conclusion:β-catenin deficiency is present in a small number of colorectal cancers and may be associated with exon 3 mutations of CTNNB1 gene.

Objective:This study aimed to explore the effect of Vaspin on adipose tissue macrophage polarization and its underlying mechanism.Methods:Fifty male SD rats, aged 8 weeks, were chosen and randomly allocated into three groups: the normal control(NC), the type 2 diabetes(T2DM), and various concentrations of Vaspin intervention(V1: 480 ng/kg, V2: 960 ng/kg, V3: 1 440 ng/kg). Vaspin was administered via intraperitoneal injection for 8 weeks. Glucose tolerance and insulin sensitivity were evaluated via intraperitoneal glucose tolerance test(IPGTT), intraperitoneal insulin tolerance test(IPITT) and hyperinsulinemic-euglycemic clamp. Adipose tissue inflammation and macrophage polarization were assessed using immunofluorescence, RT-PCR and western blotting.Results:After 8 weeks of intervention, there were no statistically significant differences in body weight and blood lipid levels among groups. IPGTT, IPITT, and hyperinsulinemic-euglycemic clamp experiments demonstrated that Vaspin intervention improved blood glucose and insulin sensitivity, exhibiting a dose-dependent manner( P<0.05). IF and RT-PCR showed that Vaspin downregulated the expression of CD11c, IL-1β, and TNF-α in eWAT, while upregulating the expression of CD206, IL-10, and PPARγ, which correlated with Vaspin concentration( P<0.05). ELISA revealed that Vaspin intervention reduced the concentrations of IL-1β and TNF-α in serum, while increasing the concentration of IL-10( P<0.05). Western blotting demonstrated that Vaspin downregulated iNOS protein expression, while upregulating Arg1, p-Akt, and PPARγ expression in a dose-dependent manner( P<0.05). Conclusion:Vaspin promotes M2 polarization of adipose tissue macrophages via PPARγ pathway, leading to reduced inflammation and improved insulin sensitivity in T2DM rats.

In recent years,researchers have shown widespread attention in the impact of commonly used clinical anesthetics on overall physiological health by influencing mitochondrial quality.These widely used anesthetics can alter mitochondrial characteristics in several ways,such as modifying mitochondrial morphology and dynamics,affecting mitochondrial function and metabolism,and altering the expression of mitochondrial proteins.These changes have a direct or indirect effect on clinical outcomes during the peri-operative period.Either beneficial or detrimental consequences are decided by multiple factors,such as the type and dosage of anesthetic used,the timing of administration,and the patient's condition.This review comprehensively presents the effects of different types of anesthetic drugs,including intravenous anesthetics,inhalational anesthetics,analgesic,and local anesthetics,on the mitochondria quality of tissue cells and their potential mechanisms,which can facilitate selecting safer anesthesia protocols,minimizing postoperative complications,optimizing patients'postoperative recovery,developing new therapeutic strategies,and opti-mizing perioperative management.

Objective:The purpose of this study is to explore the clinical characteristics of Coronavirus Disease 2019 (COVID-19) in patients with type 2 diabetes mellitus (T2DM), and analyze the risk factors for adverse outcomes.Methods:2 052 patients diagnosed with COVID-19 who were hospitalized in Shanxi Bethune Hospital between December 1, 2022 and March 20, 2023 were included. They were divided into diabetes group ( n=70) and non-diabetes group ( n=1 982) according to the presence or absence of comorbid T2DM. The two groups were matched at 1:1 via propensity score matching. Clinical characteristics and laboratory examination results of the two groups were compared. According to the outcomes during hospitalization, the two groups were further divided into two subgroups respectively. Univariate analysis and subsequent binary Logistic regression was used to analyze the risk factors of adverse outcomes in patients with COVID-19 and type 2 diabetes. Results:After the propensity score matching, the most common comorbid condition in diabetes group and non-diabetes group was hypertension. The proportion of patients with severe or critical disease in diabetes group was higher compared with non-diabetes group. The levels of hemoglobin A1c (HbA1c), fasting blood glucose (FBG), blood urea, IL-4, IL-6, IL-10, IFN-γ and TNF-α were significantly higher in the diabetes group ( P<0.05). Logistic regression analysis within the diabetes group showed that hypertension ( OR=3.640, 95% CI: 3.156 to 4.290), FBG>11 mmol/L ( OR=3.283, 95% CI: 1.416 to 7.611), HbA1c>10% ( OR=2.718, 95% CI: 1.024 to 7.213) were independent risk factors for adverse outcomes in patients with COVID-19 and type 2 diabetes(all P<0.05). Conclusions:Compared with the non-diabetes group, patients with COVID-19 and T2DM have worse inflammatory response and higher levels of inflammatory cytokines. The elevated levels of FBG and HbA1c are related to the adverse outcome in patients with COVID-19 and T2DM.

Objective:To evaluate the clinical relevant effect of hospital-wide blood glucose management in perioperative cholelithiasis patients with type 2 diabetes.Methods:The subjects of the study were patients with type 2 diabetes mellitus complicated with cholelithiasis who were treated at the Baiqiu'en Hospital in Shanxi from September 2022 to October 2023. The patients were divided into hospital-wide blood sugar management group and conventional treatment group, according to different blood glucose management they received. The differences in preoperative blood glucose control, length of stay, postoperative complications, and hospitalization expenses between the two groups were compared.Results:Compare based on the median (quartiles) of the observed indicators, patients with cholelithiasis who underwent hospital-wide blood glucose management based on insulin pumps had a higher proportion of time in range [72.00(70.21, 82.90)% vs. 64.80 (61.55,70.50)%, P<0.001)], lower average blood glucose level [9.00 (8.55, 10.44) mmol/L vs. 11.50 (10.50, 12.50) mmol/L, P<0.001], and shorter hospital stay [8.00 (7.00,13.00) days vs. 10.00 (8.00, 12.00) ) days, P<0.05]. Moreover, the incidence of postoperative complications was lower [5(11.11)% vs. 15(33.33)%, P<0.05], and hospitalization expenses were lower [16 535.34 (14 271.44, 29 569.23) yuan vs. 18 633.85 (17 482.66) yuan , 22 855.02) yuan, P<0.05] in patients who received hospital-wide blood glucose management. Conclusion:Hospital-wide blood glucose management based on insulin pumps showed favorable effects in the perioperative clinical application in cholelithiasis patients with type 2 diabetes, and could contribute to shortening the average length of stay, reducing hospitalization costs, and reducing postoperative complications.
