OBJECTIVE To evaluate the efficacy and safety of total glucosides of paeonia （TGP） in the treatment of systemic lupus erythematosus （SLE）. METHODS Randomized controlled trial （RCT） about TGP combined with western medicine versus western medicine alone for SLE treatment were retrieved from PubMed， Embase， Cochrane Library， Web of Science， CNKI， VIP， Wanfang Data， and CBM. The search period spanned from the inception of each database to June 1， 2025. After literature screening， data extraction， and quality assessment of the included studies， Meta-analysis was performed using RevMan 5.4 software. RESULTS Fifteen RCTs， involving 1 318 patients， were included. Meta-analysis results showed that compared with western medicine alone， TGP combined with western medicine significantly improved clinical efficacy [OR＝4.96， 95%CI（3.41， 7.23）， P＜0.000 01]， complement 3 [MD＝0.18， 95%CI （0.13， 0.23）， P＜0.000 01] and complement 4[MD＝0.08， 般021） 95%CI （0.04， 0.11）， P＜0.000 01]， and reduced the levels of immunoglobulin G （IgG） [MD＝－3.10， 95%CI （－3.59，－2.62）， P＜0.000 01]， IgA [MD＝－0.68， 95%CI （－0.78， －0.58）， P＜0.000 01]， IgM [MD＝－0.43， 95%CI （－0.53，－0.34）， P＜0.000 01]， systemic lupus erythematosus disease activity index （SLEDAI） [MD＝－1.59， 95%CI （－2.20， －0.99）， P＜0.000 01]， recurrence rate [OR＝0.23， 95%CI （0.13， 0.42）， P＜0.000 01] and the incidence of adverse drug reactions [OR＝ 0.54， 95%CI （0.36， 0.82）， P＝0.004]. CONCLUSIONS TGP therapy can improve clinical efficacy of SLE patients， promote the restoration of immunoglobulins and complements， reduce SLEDAI and recurrence rate and has good safety.

ObjectiveTo explore the possible mechanism of Tongbian Decoction （通便汤， TD） in treating slow transit constipation （STC）. MethodsTwenty-four SD rats were randomly divided into normal group， model group， TD group， and mosapride group， with 6 rats per group. Except for the normal group， STC models were established by intragastric administration of loperamide hydrochloride combined with normal saline. On the day following successful model establishment， rats in the TD group received 18.63 g·kg⁻¹ of TD by gavage， while those in the mosapride group received 1.605 mg·d⁻¹ of mosapride， and those in the normal group and the model group received 10 ml·kg⁻¹ of normal saline by gavage. All treatments were administered once daily for 7 consecutive days. Twenty-four hours after the last administration， fecal pellet number and fecal water content were measured. After intragastric administration of a 10% activated charcoal suspension， the small intestinal transit rate was calculated 30 minutes later. Serum levels of gastrin （GAS） and motilin （MTL） were measured by ELISA. Colonic histopathology was observed by HE staining， and mucus secretion by Alcian blue-periodic acid-Schiff （AB-PAS） staining. Ultrastructure of colon tissue was examined using transmission electron microscopy. Protein expression levels of C-kit， stem cell factor （SCF）， autophagy-related protein 5 （ATG5）， Beclin1， vesicle-associated membrane protein B （VAPB）， and protein tyrosine phosphatase interacting protein 51 （VAPB-PTPIP51） were measured by Western Blot， and the mRNA levels were detected by real-time PCR. Immunohistochemistry was used to detect SCF， C-kit， Beclin1， and ATG5 expression. The calcium content in colon tissue was determined by ELISA. ResultsCompared to the normal group， rats in the model group showed significantly reduced fecal pellet number， fecal water content， small intestinal transit rate， and serum GAS and MTL levels （P＜0.01）； the number of goblet cells decreased， and the mucosal and muscular layers of the colon became thinner； mRNA and protein expression levels of ATG5 and Beclin1 in colon tissue significantly increased， while calcium content decreased （P＜0.05 or P＜0.01）； and electron microscopy revealed vacuolar degeneration and increased autophagosomes in colonic cells. Compared to the model group， both TD group and mosapride group showed increased fecal pellet number， fecal water content， small intestinal transit rate， serum GAS and MTL levels， and colonic calcium content， along with decreased Beclin1 and ATG5 protein levels （P＜0.05 or P＜0.01）； the mucosal thickness and goblet cell number increased significantly， and autophagosomes decreased； in the TD group， ATG5 and Beclin1 mRNA levels decreased； in the mosapride group， SCF， VAPB， and PTPIP51 mRNA levels increased， while Beclin1 mRNA decreased （P＜0.05 or P＜0.01）. Compared to the mosapride group， the TD group showed higher fecal pellet number， fecal water content， serum GAS levels， colonic calcium content， and C-kit expression， along with lower ATG5 and Beclin1 levels （P＜0.05 or P＜0.01）. ConclusionTD may improve constipation symptoms by upregulating the VAPB-PTPIP51 complex during mitochondria-endoplasmic reticulum interactions， reducing autophagy of interstitial cells of Cajal， and promoting intestinal motility.

Since the founding of the People’s Republic of China, remarkable achievements have been gained in infectious disease prevention and control, and rich practical experiences have been accumulated. If these experiences are shared with developing countries, it will greatly contribute to global infectious disease control and global health security. Under the framework of Forum on China-Africa Cooperation, a series of China-Africa public health capacity training programs have been recently held in China, in order to help improve the capability of infectious disease control in African countries. This article summarized and refined good design concepts and practices from these programs, so as to provide insights into sustainable optimization of China-Africa public health capacity training and improvements of the training effectiveness.

Background: and Purpose Live cell-based assays (LCBA) are increasingly used for serological antibody detection due to their ability to preserve antigen conformation, offering moderately higher sensitivity than fixed cell-based assays. However, the clinical necessity of prioritizing LCBA for the detection of aquaporin-4 immunoglobulin G (AQP4-IgG) in neuromyelitis optica spectrum disorder (NMOSD) remains unclear, especially when compared to its established role in diagnosing myelin oligodendrocyte glycoprotein antibody-associated disease. Methods: We compared the performance of live cell-based assays using immunofluorescence (LCBA-IF) and fixed cell-based assays using immunofluorescence (FCBA-IF) in detecting AQP4-IgG in 90 cases of NMOSD meeting 2015 International Panel for Neuromyelitis Optica Diagnosis criteria, alongside 40 controls. Additionally, we further investigated the relationship between AQP4-IgG titers as measured by LCBA-IF and FCBA-IF and clinical parameters in NMOSD patients. Results: Results showed 96.9% agreement between LCBA-IF and FCBA-IF (Cohen’s κ=0.935), with a strong Spearman correlation (0.977, p<0.001). Both methods demonstrated 100% specificity, with LCBA-IF showing slightly higher sensitivity compared to FCBA-IF. Within LCBAIF-tested groups, statistically significant differences in annualized relapse rates were observed across all pairwise comparisons (low-titer vs. moderate-titer, low-titer vs. high-titer, and moderate-titer vs. high-titer; all p<0.050). However, this association reached statistical significance in some FCBA-IF-tested groups. Conclusions Overall, there is a strong concordance between LCBA-IF and FCBA-IF in detecting AQP4-IgG, where LCBA-IF shows slightly higher sensitivity. Furthermore, there is a potential link between elevated AQP4-IgG titers and an increased risk of relapse, and this correlation may appear more pronounced when using LCBA-IF.

With the continuous development of refractive surgery, people's focus has gradually shifted from improving vision to improving visual quality, and personalized laser-assisted in situ keratomileusis(LASIK)surgery has gradually become people's preferred choice. Femtosecond laser-assisted keratoplasty provides better advantages for personalized LASIK surgery. This article mainly introduces the commonly used femtosecond laser-assisted personalized LASIK surgery(FS-LASIK)in recent years, such as wavefront-optimized, wavefront-guided, topography-guided, Q value-guided(aspheric cutting), personalized surgery “Wavelight Plus” and personalized surgery when correcting patients with age-related inadequate accommodation. This article focuses on analyzing the advantages and disadvantages of different personalized FS-LASIK, as well as the research progress in recent years, and also focuses on comparing the differences between different personalized surgeries.

Objective To investigate the effects of dihydroquercetin(DHQ)on retinal ferroptosis and visual function in rats with optic nerve injury(ONI),and to elucidate the underlying mechanisms.Methods Thirty-six 8-12-week-old adult male SD rats were randomly divided into three groups:SHAM group(sham surgery without optic nerve damage,fol-lowed by saline injection at the same time points),ONI group(ONI model established by surgery,followed by saline injec-tion),DHQ+ONI group(ONI model established by surgery,followed by intraperitoneal injection of 50 mg·kg-1DHQ on days 1,3,5,and 7 post-surgery).The ONI model was constructed by optic nerve clamping.After 7 days:Brn3a immuno-fluorescence was used to observe morphological and quantitative changes in retinal ganglion cells(RGCs).Immunohisto-chemistry and Western blot were performed to analyze protein expression of nuclear factor-erythroid 2-related factor 2(Nrf2),phosphorylated protein kinase B(p-AKT),and glutathione peroxidase 4(Gpx4),Flash visual evoked potential(F-VEP)was applied to assess visual function changes.Results Immunofluorescence quantification of Brn3a-positive cells:SHAM group:(61.49±3.84)cells·mm-1,ONI group:(25.24±1.81)cells·mm-1,DHQ+ONI group:(46.50±3.51)cells·mm-1.Compared with SHAM group,ONI group showed decreased Brn3a-positive cells(P＜0.001).Compared with ONI group,DHQ+ONI group showed increased Brn3a-positive cells(P＜0.01).Immunohistochemistry and Western blot:Compared with SHAM group,ONI group showed decreased protein expression of Nrf2,p-AKT,and Gpx4(all P＜0.001).Compared with ONI group,DHQ+ONI group showed increased expression of these proteins(all P＜0.01).F-VEP meas-urements:SHAM group:P1 wave amplitude(49.87±0.81)μV,ONI group:(5.87±0.25)μV,DHQ+ONI group:(36.43±0.21)μV.Compared with SHAM group,ONI group showed reduced P1 amplitude(P＜0.001).Compared with ONI group,DHQ+ONI group showed increased P1 amplitude(P＜0.001).Conclusion DHQ may protect and repair RGCs in ONI rats by inhibiting the ferroptosis-related Nrf2/p-AKT/Gpx4 signaling pathway,thereby ameliorating vision impairment caused by ONI.

Kidney transplantation is widely recognized as the optimal treatment for children with end-stage renal disease(ESRD),offering significant improvements in growth,development,and long-term quality of life compared with prolonged dialysis.However,kidney transplantation in low-age(＜5 years old)and low-weight(＜15 kg)children presents significant clinical challenges due to their delicate vas-cular structures,limited surgical space,and complex perioperative management.This report presents two cases of kidney transplantation in low-age,low-weight children performed at Peking University People's Hospital.Case 1:a 2-year-3-month-old boy(8.8 kg),presenting a preoperative serum creatinine of 248μmol/L post-dialysis and the estimated glomerular filtration rates(eGFR)of 35.17 mL/(min·1.73 m2).Case 2:a 3-year-8-month-old girl(11.25 kg),presenting a preoperative creatinine of 281 μmol/L post-dialysis and the eGFR of 22.63 mL/(min·1.73 m2).Both recipients underwent transplantation via the extraperitoneal approach,with end-to-side anastomosis of the donor renal artery and vein to the recipient's common iliac artery and vein,respectively.The ureters were anastomosed to the bladder using the tunnel technique,and double-J stents were placed intraoperatively.The surgeries were uneventful,and both pa-tients exhibited rapid recovery of renal function.Postoperatively,serum creatinine levels decreased to 26μmol/L(Case 1)and 39 μmol/L(Case 2)by the third day,with the eGFR reaching 245.23 mL/(min·1.73 m2)and 164.12 mL/(min·1.73 m2),respectively.No complications,such as vascular thrombosis,ureteral stenosis,or abdominal compartment syndrome were observed during follow-up.A comprehensive literature review was conducted to contextualize these cases within global advancements in pediatric renal transplantation.Current evidence highlights the growing adoption of kidney transplantation for low-age,low-weight children,though debates persist regarding optimal surgical strategies(specifical-ly,the intraperitoneal versus extraperitoneal approaches).This case report underscores the feasibility of the extraperitoneal approach in overcoming anatomical limitations of low-weight pediatric recipients,with distinct advantages including reduced gastrointestinal complications and enhanced accessibility for post-operative ultrasound monitoring.Furthermore,mean arterial pressure(MAP)and central venous pressure(C VP)were systematically monitored intraoperatively to ensure optimal renal blood perfusion and graft viability.Our single-center experience provides valuable insights into surgical strategy selection and peri-operative management for this high-risk population.Nevertheless,larger multicenter studies are warranted to validate long-term outcomes and refine standardized protocols.

Transcatheter aortic valve replacement(TAVR)has become an important therapeutic approach for severe aortic stenosis.However,complications associated with TAVR cannot be overlooked,among which contrast agents induced acute kidney injury(AKI)is a common complication.To explore methods to reduce the occurrence of AKI,this article reports two cases of successful treatment of severe aortic stenosis by TAVR under pure echocardiographic guidance,both of whom were elderly women aged 75 and 69,respectively,and both were implanted with a Evolute Pro 26 mm valve.Postoperative echocardiography showed good valve positioning and function.

Objective:To investigate the factors influencing the occurrence of deep vein thrombosis(DVT)in patients with knee osteoarthritis after artificial total knee arthroplasty(TKA)and to construct a nomogram prediction model.Methods:A total of 120 patients with knee osteoarthritis underwent TKA from Dec 2020 to Dec 2022 were selected.The patients were divided into DVT group(n=20)and non-DVT group(n=100)according to whether DVT occurred after surgery.Receiver operating characteristic(ROC)curve was used to analyze the predictive value of each influencing factor to the occurrence of DVT.Multivariable logistic regression was used to analyze the factors affecting the occurrence of DVT.The nomogram prediction model of DVT was constructed by the R software 4.0"rms"package.The calibration and decision curves were used to internally validate and clinically assess the predictive efficacy of the nomogram prediction model.Results:There were significant differences between DVT group and non-DVT group in age,body mass index(BMI),diabetes mellitus,hyperlipidaemia,plasma D-dimer level,operative time,intraoperative haemorrhage,post-operative bedrest,and anaesthesia modality(P＜0.05).ROC curve showed that the AUC for age,BMI,plasma D-dimer,operative time,intraoperative haemorrhage,and postoperative bedrest were 0.663,0.678,0.985,0.856,0.925 and 0.925,respectively.Multivariable logistic regression analysis showed that age≥71 years old,BMI≥25.47 kg/m2,diabetes mellitus,hyperlipidaemia,plasma D-dimer level≥0.69 mg/L,and general anaesthesia were independent risk factors for postoperative DVT(P＜0.05).The calibration curve of the nomogram prediction model was close to the original and ideal curves,with a C-index of 0.813(0.721-0.905),indicating a high degree of fit.The threshold value of the nomogram prediction model was＞0.17,which could provide a net clinical benefit.And its net clinical benefit was higher than age,BMI,diabetes mellitus,hyperlipidemia,plasma D-dimer,and anaesthesia mode.Conclusions:The factors affecting the occurrence of DVT in patients with knee osteoarthritis after TKA are age,BMI,diabetes mellitus,hyperlipidaemia,plasma D-dimer level,operative time,intraoperative haemorrhage,postoperative bedtrest,and anaesthesia mode.The personalized neomorph prediction model constructed by these predictive factors can help to predict and evaluate whether DVT will be occurred in patients with knee osteoarthritis after TKA,so as to intervene early,reduce the incidence and improve the prognosis.
