OBJECTIVE To compare the efficacy and safety of different classes of antibacterial agents in hospitalized adult patients with community-acquired pneumonia （CAP）.METHODS PubMed， Embase，the Cochrane Library，Web of Science，CNKI，and Wanfang data were searched from inception to January 1，2026，to identify randomized controlled trials that evaluated different classes of antibacterial agents in hospitalized adults with CAP.After screening the literature， extracting the data， and evaluating the quality of the literature， a network meta-analysis was performed using Stata 18.0.RESULTS A total of 25 studies were included，involving 7 863 patients. In terms of efficacy，compared with carbapenems，penicillins，cephalosporins，macrolides，and pleuromutilins were associated with significantly higher treatment failure rates （ P ＜0.05），carbapenems and traditional tetracyclines were ranked as the top two by the surface under the cumulative ranking curve area （SUCRA）. No statistically significant differences were observed in mortality among the interventions （ P ＞0.05），carbapenems and other quinolones were ranked as the top two by SUCRA. In terms of safety，no statistically significant differences were observed among the interventions in the incidence of adverse events or discontinuation rates （ P ＞0.05）；traditional tetracyclines and novel tetracyclines were ranked as the top two by SUCRA for the incidence of adverse events，while novel tetracyclines and pleuromutilins were ranked as the top two by SUCRA for discontinuation rates.CONCLUSIONS Carbapenems significantly reduced the treatment failure rate in hospitalized adults with CAP. The safety profiles of all antibacterial agents were comparable， with novel tetracyclines showing a more favorable safety profile.

ObjectiveStarting from the etiology， pathogenesis， and treatment strategies of endometriosis and adenomyosis， to integrate and sort out the academic characteristics of contemporary renowned experts and schools in the field of traditional Chinese medicine gynecology. 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.

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 clinical efficacy of haploidentical high-dose in vitro non-T-cell-depleted peripheral blood hematopoietic stem cell transplantation (haplo-HDPSCT) in treating adult patients with Ph + acute lymphoblastic leukemia (Ph + ALL) . Method:This retrospective analysis was conducted on the clinical efficacy of 25 adult patients with Ph + ALL who underwent haplo-HDPSCT from July 2011 to June 2022 at our hospital. Results:This study included 25 patients with a median age of 27 (16-61) years, consisting of 12 males and 13 females. CR1 and ≥CR2 before transplantation were found in 23 and 2 cases, positive and negative minimal residual lesions were observed in 8 and 17 cases, and myeloablative conditioning and reduced-intensity conditioning were reported in 21 and 4 cases, respectively. Hematopoietic function was restored in all 25 patients after stem cell infusion. Of the 25 patients who underwent transplantation, 16 developed acute graft-versus-host disease (aGVHD). The cumulative incidence rates of Ⅱ-Ⅳ and Ⅲ-Ⅳ aGVHD were (40.4±11.3) % and (4.8±4.6) %, respectively. Four patients experienced relapse after transplantation, the cumulative relapse rates at 1 and 2 years after transplantation were (4.0±3.9) % and (14.5±7.9) %, respectively. The 2-year overall survival rate after transplantation was (81.3±8.5) % and the disease-free survival rate was (77.1±9.1) %.Conclusion:This study reveals that the unique haplo-HDPSCT protocol achieves good clinical efficacy in Ph + ALL treatment.

Objective:To investigate the therapeutic effect and potential mechanism of Nepetoidin B on rheumatoid arthritis (RA).Methods:DBA/1 mice were divided into four groups using the random number method, namely the control group, model group, methotrexate group, and Nepetoidin B group. The collagen-induced arthritis (CIA) model was prepared. Mice were treated from day 21th to day 60th. Arthritis symptoms were evaluated every three days during treatment. At the end of treatment, pathological changes of joint tissue were observed through HE staining. Serum IL-17, IL-6, MDA, and NO levels were measured using ELISA and biochemical colorimetric assays. The Nrf2/HO1 pathway in joint tissues was detected using western blot. A group of CIA mice was treated with Nepetoidin B, followed by an Nrf2 inhibitor to validate the mechanism. One-way analysis of variance was used to compare between multiple groups with homogeneity of variance, pairwise comparison using LSD- t test. Results:The study found that mice treated with methotrexate and Nepetoidin B exhibited a significant reduction in arthritis scores(CIA+Meth group 5.2±1.3, CIA+NepB group 6.8±1.2 vs. CIA group 11.0±1.7, t=6.69, P=0.004; t=5.00, P=0.009), and joint histopathology compared to the CIA mice(CIA+Meth group 1.5±1.0, CIA+NepB group 2.2±0.8 vs. CIA group 4.0±0.9, t=4.44, P<0.001; t=3.84, P=0.005). Additionally, there was a significant decrease in serum IL-17[CIA+Meth group(257±69)ng/ml, CIA+NepB group (279±103)ng/ml vs. CIA group(414±71)ng/ml, t=3.86, P=0.006; t=2.63, P=0.020], IL-6[CIA+Meth group(32±6)ng/ml, CIA+NepB group (44±5)ng/ml vs. CIA group(56±11)ng/ml, t=4.69, P<0.001; t=2.48, P=0.040) ,MDA [CIA+Meth group(22±4)μmol/L, CIA+NepB group(22±8)μmol/L vs. CIA group(34±11)μmol/L, t=2.77, P=0.038; t=2.29, P=0.049]and NO[ CIA+Meth group(37±12)μmol/L, CIA+NepB group(37±11)μmol/L vs. CIA group(56±12)μmol/L, t=2.71, P=0.040; t=2.90, P=0.035] levels, and a significant elevation in the Nrf2( 0.263±0.021, 0.273±0.022 vs. 0.221±0.034, t=3.18, P=0.044; t=2.70, P=0.049)/HO1 (0.524±0.021, 0.501±0.014 vs. 0.453±0.033, t=3.95, P=0.006; t=3.41, P=0.032) pathway in methotrexate and Nepetoidin B treated group. It was also observed that Nrf2 inhibitors could counteract the treatment effects of Nepetoidin B on arthritis (1.8±0.8 vs. 3.2±0.8, t=3.07, P=0.024). Conclusion:Nepetoidin B has the ability to inhibit oxidative stress by activating the Nrf2/HO1 pathway, which alleviates collagen-induced arthritis in mice.

Objective:To explore the effect and mechanism of Chlorfortunone A(ChlA) in the treatment of diabetic nephropathy(DN) in mice.Methods:The DN model mice were assigned to DN, low-dose ChlA(ChlAL) and high-dose ChlA(ChlAH), and the normal control groups(Ctrl). Kidney tissue was analyzed via HE and Masson staining, and urine albumin, fasting blood glucose and kidney weight were measured. Collagen1 and α-SMA proteins were detected in renal tissues. The level of GSH-px, SOD, CAT, and TGF-β were detected. The TGF-β/Smad2 pathway in kidney tissue was detected. The mechanism was verified by setting the high glucose+ ChlA+ TGF-β group in MPC-5 cells. The proliferation of the cells and DCFDA staining were detected.Results:Compared to the Ctrl group, the DN group had significantly higher UACR and kidney weight( P<0.001). High-dose ChlA reduced UACR and kidney weight( P<0.05), with no effect on blood glucose( P>0.05). Masson staining showed reduced fibrosis with ChlA treatment. Collagen I and α-SMA expressions were significantly higher in DN( P<0.001) and decreased with ChlA treatment( P<0.05). GSH-px, SOD, and CAT levels were lower in DN( P<0.001), while TGF-β was elevated( P<0.001); ChlA increased antioxidant enzymes and decreased TGF-β( P<0.05). The TGF-β/Smad2 pathway was upregulated in DN( P<0.001) and inhibited by ChlA( P<0.001). In vitro, ChlA reduced cell proliferation( P<0.05) and increased ROS levels( P<0.001). Conclusions:ChlA alleviates kidney injury and fibrosis in DN mice, reduces oxidative stress, which may be related to the inhibition of the TGF-β/Smad2 pathway.
