OBJECTIVE To observe the clinical efficacy of mycophenolate mofetil （MMF） combined with Budesonide enteric capsules in the treatment of high-risk progressive immunoglobulin A nephropathy （IgAN）. METHODS A total of 150 adult patients with high-risk progressive IgAN who attended the Department of Nephrology， Chongqing University Three Gorges Hospital， between August 1， 2024 and March 1， 2025 were enrolled in this study. The control group （ n ＝94） received MMF combined with glucocorticoid， while the observation group （ n ＝56） received MMF combined with Budesonide enteric capsules. The 24-hour urine protein （24 h UP）， estimated glomerular filtration rate （eGFR）， and albumin （ALB） levels of patients in both groups were compared at 1， 2， 3， and 6 months post-treatment. The complete response （CR） rate and overall response rate were calculated for both groups at 1， 2， 3， and 6 months post-treatment. Adverse reactions occurring during treatment were compared between the two groups. RESULTS Compared with before treatment， 24 h UP decreased significantly in both groups at different time points after treatment （ P ＜0.05）， and ALB increased significantly （ P ＜0.05）. However， there was no significant change in eGFR （ P ＞0.05）. The 24 h UP in the observation group at 1， 2， and 3 months after treatment was significantly lower than that of the control group （ P ＜0.05）， while the ALB level was significan tly higher （ P ＜0.05）. However， at 6 months after treatment， there was no statistically significant difference in these two indicators between the two groups （ P ＞0.05）. There was no statistically significant difference in eGFR between the two groups at different time points after treatment （ P ＞0.05）. The overall response rates in the observation group at 1 and 2 months after treatment were significantly higher than those in the control group （ P ＜0.05）. There was no statistically significant difference in the overall response rate at the remaining treatment time points and the CR rate at all time points between the two groups （ P ＞0.05）. Patients in the observation group had significantly lower rates of skin abnormalities， elevated blood glucose， and overall adverse reactions compared with the control group （ P ＜0.05）. CONCLUSIONS Compared with MMF combined with glucocorticoids， MMF combined with Budesonide enteric capsules for the treatment of high-risk progressive IgAN patients can reduce proteinuria and improve serum ALB levels more quickly， significantly increase the early overall response rate， and significantly reduce glucocorticoid-related skin adverse reactions， blood glucose elevation， and the overall incidence of adverse reactions， demonstrating a better short-term benefits.

This study aimed to investigate the anti-inflammatory and antioxidant effects of atractylon on lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice. Changes in lung function parameters were measured in mice after intraperitoneal administration of atractylon. Pathological changes in lung tissue were observed by H&E staining, and the degree of pulmonary edema was assessed by the lung wet/dry weight ratio (W/D). Kit assays were used to detect changes in oxidative stress markers in mouse serum and the protein concentration in bronchoalveolar lavage fluid (BALF). ELISA was employed to measure the expression levels of inflammatory cytokines in BALF and serum. Western blot was used to detect the expression levels of proteins related to the cGAS-STING pathway and vascular cell adhesion molecule-1 (VCAM-1) in lung tissue. Results showed that, compared to the ALI model group, mice in the low-dose and high-dose atractylon groups exhibited significant improvement in lung function parameters, alleviated pulmonary edema, and reduced inflammatory cell infiltration in lung tissue. Protein content and inflammatory cytokine levels in serum and BALF were decreased, while serum oxidative stress indicators were improved. Western blot results further indicated that atractylon could regulate the cGAS-STING pathway, blocking the generation of inflammatory signals, and simultaneously inhibit VCAM-1 expression, thereby reducing pulmonary vascular injury. The results suggest that atractylon may alleviate LPS-induced ALI by modulating the cGAS-STING signaling pathway, reducing the expression of pro-inflammatory cytokines and the production of pro-inflammatory mediators, and improving vascular endothelial injury. This study provides a new potential target and theoretical basis for the treatment of ALI, as well as a potential drug candidate for ALI therapy.

Steroid-induced osteonecrosis of the femoral head （SONFH） is a severe musculoskeletal disorder often induced by the prolonged or excessive use of glucocorticoids. Characterized by ischemia of bone cells， necrosis， and trabecular fractures， SONFH is accompanied by pain， femoral head collapse， and joint dysfunction， which can lead to disability in severe cases. The pathogenesis of SONFH involves hormone-induced osteoblast apoptosis， bone microvascular endothelial cell （BMEC） apoptosis， oxidative stress， and inflammatory responses. The phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） signaling pathway plays a pivotal role in the development of the disease. Modulating the PI3K/Akt signaling pathway can promote Akt phosphorylation， thereby stimulating the osteogenic differentiation of bone marrow mesenchymal stem cells and osteoblasts， promoting angiogenesis in BMECs， and inhibiting osteoclastogenesis. The research on the treatment of SONFH with traditional Chinese medicine （TCM） has gained increasing attention. Recent studies have shown that TCM monomers and compounds have potential therapeutic effect on SONFH by intervening in the PI3K/Akt signaling pathway. These studies not only provide a scientific basis for the application of TCM in the treatment of SONFH but also offer new ideas for the development of new therapeutic strategies. This review summarized the progress in Chinese and international research on the PI3K/Akt signaling pathway in SONFH over the past five years. It involved the composition and transmission mechanisms of the signaling pathway， as well as its regulatory effects on osteoblasts， mesenchymal stem cells， osteoclasts， BMECs， and other cells. Additionally， the review explored the TCM understanding of SONFH and the application of TCM monomers and compounds in the intervention of the PI3K/Akt pathway. By systematically analyzing and organizing these research findings， this article aimed to provide references and point out directions for the clinical prevention and treatment of SONFH and promote further development of TCM in this field. With in-depth research on the PI3K/Akt pathway and the modern application of TCM， it is expected to bring safer and more effective treatment options for patients with SONFH.

Objective:To evaluate the clinical value and safety of an intraperitoneal chemotherapy port technique in patients with gastric cancer and peritoneal metastases undergoing intraperitoneal chemotherapy.Methods:This was a retrospective, descriptive case analysis. From November 2022 to October 2024, patients diagnosed with gastric cancer and peritoneal metastases at Wuxi Branch of Ruijin Hospital, Shanghai Jiao Tong University School of Medicine with an expected survival >3 months, underwent laparoscopic exploration combined with implantation of an intraperitoneal chemotherapy port [PORT-A-CATH II system (Model 21-4055-24)] implantation. The procedure was as follows: (1) after laparoscopic exploration, a 4-cm skin incision was made at a predetermined site and a subcutaneous pocket created by dissecting to the muscle fascia and removing subcutaneous fat as needed to position the port septum 0.5-1.0 cm from the skin surface; (2) under direct laparoscopic visualization, the abdominal cavity was punctured and a guidewire inserted, followed by an 8.5 Fr sheath, through which a catheter with three trimmed side holes was placed after removal of the sheath; (3) the catheter length in the abdominal cavity was adjusted to 25–30 cm and the catheter trimmed, and connected to the port base, ensuring it extended beyond the connector's visible hole; (4) the whole port was placed within the subcutaneous pocket, and non-absorbable sutures used to create a double purse-string suture at the catheter's abdominal entry, forming an anti-reflux ring; (5) non-absorbable sutures were used to securely fix the port to the fascia through its four base holes and the exposed catheter segments on the fascia sutured and buried; (6) patency was confirmed by injecting saline and followed by intermittent skin closure provided there was no bleeding; and (7) the catheter tip was positioned in the pelvic cavity under laparoscopic guidance. Postoperatively, the patients underwent normothermic intraperitoneal and systemic treatment. The port infusion protocol involved disinfecting the skin (>10 cm diameter) around the port, confirming the puncture site, inserting a Huber needle vertically at 90° to the port base, infusing 100 mL saline to ensure patency, followed by continuous infusion of 1000 mL paclitaxel solution, and sealing with 20 mL saline before removing the needle. No saline flushing was required between chemotherapy infusions. The primary outcomes were the incidence and management of complications post-port implantation.Results:The study cohort comprised 225 patients with gastric cancer and peritoneal metastases. Using standardized port implantation and postoperative puncture procedures, the complication rate during follow-up was 14.2% (32/225), including effusion in 14 patients (6.2%), port infection in 10 (4.4%), incision dehiscence in four (1.8%), port inversion in two (0.9%), hematoma in one (0.4%), and catheter rupture in one (0.4%). Seventy-five percent (24/32) of patients with complications recovered and continued using the port after conservative treatments (e. g., aspiration of effusions, antibiotic therapy, incision management), whereas the remaining 25.0% (8/32) with complications required surgical removal of the port because the treatment was ineffective. The presence of preoperative ascites ( P=0.019) and peritoneal cancer index score>15 ( P=0.038) were significantly associated with development of complications. Conclusions:Our standardized procedure for intraperitoneal chemotherapy port implantation is safe and feasible for patients with gastric cancer and peritoneal metastases, having a low overall complication rate. Most complications can be successfully managed with conservative treatment, the device thus providing reliable support for intraperitoneal chemotherapy.

Objective:To evaluate the epidemiological protective effect of a booster dose of acellular DTP vaccine (DTaP) against pertussis in 6-year-old children.Methods:A retrospective cohort study was conducted to compare the incidence of pertussis in 6-year-old children who received DTaP versus DT vaccine boosters in 2023 over a two-year period from May 2023 to May 2025. The protective effect of the fifth dose of DTaP against pertussis in 6-year-old children was evaluated.Results:A total of 960 participants were enrolled in this study, including 480 children in the experimental group who received the fifth dose of DTaP vaccine and 480 children in the control group who received the DT vaccine booster. Baseline characteristics were balanced between the two groups. There were six confirmed cases of pertussis in the experimental group, with a reported incidence rate of 1.25%. In the control group, 14 pertussis cases were reported, with a reported incidence rate of 2.92%. The protective effectiveness(VE) of the DTaP vaccine against pertussis was 57.14% (95% CI:-10.59%-83.39%). For 6-year-old children who completed the booster immunization, the incidence data of pertussis were collected from the 14 th day after vaccination (i.e., the study day 0). Based on the annual cumulative incidence rate, the VE of DTaP against pertussis at 6, 12, 18, and 24 months after vaccination was 100%, 63.80% (95% CI:-14.49%-88.55%), 64.59% (95% CI: 1.17%-87.31%), and 57.60% (95% CI:-10.80%-83.78%), respectively. In the DTaP group, the annual cumulative incidence rate of 12 to 24 months did not show a significant upward or downward trend ( Z=-0.995, P=0.320). Conclusion:Boosting 6-year-old children with the DTaP vaccine provides measurable protection against pertussis. The protective efficacy is significant in the early stage (0 to 6 months) after vaccination, and it still remains effective at 12 to 24 months.

ADC189 is a novel drug of cap-dependent endonuclease inhibitor. In our study, its antiviral efficacy was evaluated in vitro and in vivo, and compared with baloxavir marboxil and oseltamivir. A first-in-human phase I study in healthy volunteers included single ascending dose (SAD) and food effect (FE) parts. In the preclinical study, ADC189 showed potent antiviral activity against various types of influenza viruses, including H1N1, H3N2, influenza B virus, and highly pathogenic avian influenza, comparable to baloxavir marboxil. Additionally, ADC189 exhibited much better antiviral efficacy than oseltamivir in H1N1 infected mice. In the phase I study, ADC189 was rapidly metabolized to ADC189-I07, and its exposure increased proportionally with the dose. The terminal elimination half-life (T_1/2) ranged from 76.69 to 98.28 hours. Of note, food had no effect on the concentration, clearance, and exposure of ADC189. It was well tolerated, with few treatment-emergent adverse events (TEAEs) reported and no serious adverse events (SAEs). ADC189 demonstrated excellent antiviral efficacy both in vitro and in vivo. It was safe, well-tolerated, and had favorable pharmacokinetic characteristics in healthy volunteers, supporting its potential for single oral dosing in clinical practice.

Objective To observe changes of dynamic functional connectivity(dFC)of brain networks in different stages of Parkinson disease(PD).Methods Totally 52 early-stage PD patients(early PD group),36 late-stage PD patients(late PD group)and 38 healthy controls(HC group)were prospectively enrolled,and resting-state functional MRI were performed.The sliding window,independent component analysis and k-means clustering were used to extract dFC intensity and temporal properties,including fractional windows,dwell time and transition frequency.Results Network connectivity patterns within and between visual network(VIS),sensorimotor network(SMN),default mode network(DMN),cerebellar network(CB)and cognitive executive network(CEN)were altered in PD patients.Four dFC states were identified,in which connections between components in states Ⅰ and Ⅱ were compact,while in states Ⅲ and Ⅳ were sparse.The fractional window and dwell time of late PD group,early PD group and HC group successively increased under state Ⅱ,but successively decreased under state Ⅲ(all P＜0.05).Under state Ⅰ and Ⅳ,no significant difference of fractional window nor dwell time was found between early PD group and late PD group(both P＞0.05),and the above indexes under state Ⅰ were both lower than those in HC group(all P＜0.05),the fraction window under state Ⅳ was higher than that in HC group(both P＜0.05).Conclusion The temporal properties of dFC in PD patients were altered,characterized by increased tendency toward segregated states.Furthermore,fractional windows and dwell time were associated with PD disease stages,suggesting that dFC parameters might serve as novel biomarkers for assessing clinical progression of PD.

The 2021 version of the Baveno Ⅶ consensus on portal hypertension and the 2023 guidelines from the European Association for the Study of the Liver define recompensated cirrhosis as the restoration and stabilization of liver function, improvement of liver fibrosis, and absence of decompensated cirrhosis for a long time following effective treatment of the underlying etiology of cirrhosis. Recompensated cirrhosis has become an important research direction in the field with the gradually increasing number of these patients. Temporary recompensation, stable recompensation, and long-term recompensation are the three stages into which patients with cirrhosis are divided, based on varying recompensation stages. Clinical characteristics and prognosis are significantly different among different stages. Patients in the temporary compensation stage have significant fluctuations in their condition and poor stability, with a high risk of recurrent complications. The prognosis of patients in the stable recompensation stage is significantly affected by the cause and the type of initial decompensation event, while the condition of patients in the long-term recompensation stage is more stable, and the long-term prognosis is close to that of compensated cirrhosis. This article aims to summarize and explore the recompensation rates at different stages of liver cirrhosis, the occurrence risk of various complications and liver cancer, and long-term management and treatment following recompensation, providing new directions for future research in this field.

Objective:To analyze the application of mobile application-based decision support tools in patient treatment decision-making both domestically and internationally, and to provide references and insights for future research in this area.Methods:A search was conducted in databases including China National Knowledge Infrastructure, VIP, Wanfang, China Biology Medicine disc, PubMed, Embase, CINAHL, and Web of Science for relevant studies on the application of mobile application-based decision support tools in patient treatment decision-making, with the search period extending from database inception to April 1, 2024. The scope review methodology by Arksey and O'Malley was used to guide the literature summary and analysis.Results:A total of 9 studies were included in the review. The main presentation forms of mobile application-based decision support tools in patient treatment decision-making were text, charts, and videos. The main contents included assessing patients' decision-making needs, providing informational support, and summarizing the decision-making process. The evaluation criteria focused on 2 areas: decision quality (preparedness for decision-making, self-efficacy, decision conflict, regret, actual participation, satisfaction, knowledge of the disease, and treatment choices) and psychological state.Conclusions:It is recommended that future researchers fully consider patients' treatment decision-making needs and preferences, provide a more diverse range of information presentation methods, and strengthen the comprehensiveness and scientific basis of the content. These improvements aim to enhance decision quality and, through multi-center, large-sample, high-quality studies, further explore the effectiveness of these tools in clinical applications, thereby providing more evidence for their widespread adoption.
