Long-term hypertension causes excessive vascular remodeling and leads to adverse cardiovascular events. Balance of ubiquitination and deubiquitination has been linked to several chronic conditions, including pathological vascular remodeling. In this study, we discovered that the expression of ubiquitin-specific protease 25 (USP25) is significantly up-regulated in angiotensin II (Ang II)-challenged mouse aorta. Knockout of Usp25 augments Ang II-induced vascular injury such as fibrosis and endothelial to mesenchymal transition (EndMT). Mechanistically, we found that USP25 interacts directly with Forkhead box O3 (FOXO3) and removes the K63-linked ubiquitin chain on the K258 site of FOXO3. We also showed that this USP25-mediated deubiquitination of FOXO3 increases its binding to light chain 3 beta isoform and autophagosomic-lysosomal degradation of FOXO3. In addition, we further validated the biological function of USP25 by overexpressing USP25 in the mouse aorta with AAV9 vectors. Our studies identified FOXO3 as a new substrate of USP25 and showed that USP25 may be a potential therapeutic target for excessive vascular remodeling-associated diseases.

Obesity, as a chronic recurrent disease, has become a major public health challenge in China. To implement the requirements of the Healthy China Initiative (2019—2030), under domestic guidelines or consensus statements on overweight and obesity, and in alignment with the latest scientific advances globally, the Quality control protocol for adult overweight and obesity screening in health management (examination) institutions (2025 edition) was developed. This protocol was drafted by the Health Management Center of Shanghai Changzheng Hospital and formulated through multiple rounds of deliberation by experts in China’s health examination quality control field. The protocol establishes unified standards for screening facilities, personnel qualifications, and measurement or testing procedures. It defines specific screening items, outlines a standardized screening pathway, and sets requirements for the final medical review, ensuring the scientific validity, effectiveness, and safety of the screening process. The implementation of this protocol will enhance the consistency of weight management practices for adults across health examination institutions and strengthen the quality control of overweight and obesity screening programs.

Objective To explore clinical effect of Jiawei Sangju decoction combined with oseltamivir in the treatment of influenza B complicated with benign acute childhood myositis(BACM).Methods Sixty children with influenza B complicated with BACM hospitalized in the Department of Pediatrics,Wenzhou Hospital of Integrated Traditional Chinese and Western Medicine from January 2021 to January 2024 were selected and divided into control group and study group according to random number table method,with 30 cases in each group.The control group was treated with oseltamivir,and the study group was treated with Jiawei Sangju decoction combined with oseltamivir.The clinical efficacy,symptom improvement time and aspartate transaminase(AST),alanine transaminase(ALT),creatine kinase(CK),creatine kinase isozyme(CK-MB),lactate dehydrogenase(LDH)and myoglobin(Mb)before and after treatment were compared between two groups.Results After treatment,the total effective rate of study group was significantly higher than that of control group(χ2=5.455,P=0.020).The duration of fever and leg pain relief in study group were significantly shorter than those in control group(P<0.05).After 5 days of treatment,the levels of AST,CK,CK-MB,LDH and Mb in two groups were significantly lower than before treatment(P<0.05),and the levels of AST,CK,CK-MB,LDH and Mb in study group were significantly lower than those in control group(P<0.05).Conclusion Jiawei Sangju decoction combined with oseltamivir can improve the symptoms of influenza B with BACM,reduce the levels of muscle enzyme and Mb,and have a positive effect on the prognosis of children.

Loganin(LOG),a bioactive compound derived from Cornus officinalis Siebold & Zucc,has been understudied in the context of osteoarthritis(OA)treatment.In this study,we induced an inflammatory response in chondrocytes using lipopolysaccharide(LPS)and subsequently treated these cells with LOG.We employed fluorescence analysis to quantify reactive oxygen species(ROS)levels and measured the expression of NLRP3 and nuclear factor erythropoietin-2-related factor 2(NRF2)using real-time quantitative polymerase chain reaction(qRT-PCR),Western blotting,and immunofluorescence(IF)techniques.Additionally,we developed an OA mouse model by performing medial meniscus destabilization(DMM)surgery and monitored disease progression through micro-com-puted tomography(micro-CT),hematoxylin and eosin(H&E)staining,safranin O and fast green(S&F)staining,and immunohisto-chemical(IHC)analysis.Our results indicate that LOG significantly reduced LPS-induced ROS levels in chondrocytes,inhibited the activation of the NLRP3 inflammasome,and enhanced NRF2/heme oxygenase 1(HO-1)signaling.In vivo,LOG treatment mitigated cartilage degradation and osteophyte formation triggered by DMM surgery,decreased NLRP3 expression,and increased NRF2 expres-sion.These findings suggest that LOG has a protective effect against OA,potentially delaying disease progression by inhibiting the ROS-NLRP3-IL-1β axis and activating the NRF2/HO-1 pathway.

Objective:To explore the dynamic temporal variability of brain functional networks in individuals with internet gaming disorder(IGD)using dynamic functional connectivity density(dFCD).Methods:From January 2019 to December 2021, resting-state functional magnetic resonance imaging data were recruited from 55 patients with IGD and demographically matched 50 healthy controls.Data analysis was performed by IBM SPSS 21.0 software. The functional connectivity density(FCD) combined with sliding window analysis was employed to calculate the temporal variability of global functional connectivity.FCD in whole brain was further devided into ipsilateral and cotralateral parts.The temporal variability of dFCD was further quantified utilizing the standard deviations of whole brain, intra-, and inter-hemispheric FCD. Finally, Pearson correlation analysis was performed between dFCD variance in differential brain regions and clinical behaviors.Results:The inter-hemispheric dFCD in the left posterior cingulate cortex(-0.16±0.24) and the left precuneus(-0.08±0.23) in patients with IGD were lower that those in healthy controls(0.002±0.260, 0.12±0.36)( t=-3.502, -4.160, both P<0.05).And the intra-hemispheric dFCD in the left calcarine, the left precuneus, and the left posterior cingulate cortex in patients with IGD were lower that those in healthy controls( t=-3.809, -4.360, -3.561, all P<0.05).Moreover, abnormal global dFCD variability of the calcarine and ipsilateral dFCD variability of the PCC negatively correlated with the severity of IGD( r=-0.380, -0.413, both P<0.05). Conclusion:Patients with IGD show intra-and inter-hemispheric dFCD differences in the visual attention network and default mode network, which may respond to the underlying neurobiological basis for the presence of cognitive dysfunction and impaired concentration.

Objective:To investigate the impact of residual cholesterol (RC) on the progression of arteriosclerosis in individuals receiving physical examination.Methods:A cross-sectional study. Participants aged 18 years and above who underwent arteriosclerosis testing at the Health Management Center of Zigong Fourth People′s Hospital from January to December 2023 were selected as the subjects of the study. A total of 9 016 subjects were included in this study, of whom 6 213 were considered to have arteriosclerosis. The physical examination conclusions, basic information (age, gender, body mass index, waist circumference, blood pressure, history of hypertension, history of smoking and drinking), and biochemical indicators (lipids, fasting blood glucose, liver and kidney function) were extracted in those individuals. Based on the examination results, the subjects were categorized into arteriosclerosis and normal groups. The RC levels of the participants were calculated using a formula and then the subjects were categorized into binary and quartile RC groups. Additionally, four regression models were used to analyze the impact of RC levels on the progression of arteriosclerosis while adjusting for various confounding factors.Results:The RC level was (0.63±0.44) mmol/L in the normal group and (0.76±0.61) mmol/L in the arteriosclerosis group. Based on level of RC, the normal group was divided into two subgroups: 652 individuals with elevated RC level and 2 241 with normal RC level. In the arteriosclerosis group, there were 2 069 individuals with elevated RC level and 4 144 with normal RC level. Grouped according to quartiles of RC level, the number of individuals with RC in the Q1-Q4 interval in the normal group was 838 (28.97%), 752 (25.99%), 760 (26.27%), and 543 (18.77%), respectively, showing a gradual decreasing trend. The number of individuals with RC in the Q1-Q4 interval in the arteriosclerosis group was 1 414 (22.76%), 1 438 (23.15%), 1 589 (25.58%), and 1 771 (28.51%), respectively, showing a gradual increasing trend. The difference between the groups was statistically significant ( P<0.05). After adjusting for various factors by four regression models, it was found that elevated RC levels increased the risk of arteriosclerosis progression, with a odds ratio ( OR) of 1.381, 1.242, 1.233, and 1.214, respectively. Additionally, individuals in the Q4 RC level quartile had 1.502, 1.318, 1.311, and 1.284-times higher risk of arteriosclerosis progression when compared to those in the Q1 quartile. Conclusion:The impact of RC on the progression of arteriosclerosis tend to stabilize and remain consistent, indicating that elevated RC is an independent risk factor for the progression of arteriosclerosis.

Objective:To present the surgical details of manual double-layer suturing in patients with obesity combined type 2 diabetes mellitus by three-incision laparoscopic single-anastomosis duodenal-jejunal bypass with sleeve gastrectomy .Methods:Clinical data and follow-up information of 52 obesity combined type 2 diabetes mellitus patients (BMI 27.59-43.71 kg/m2) who underwent three-incision laparoscopic single-anastomosis duodenal-jejunal bypass with sleeve gastrectomy from Jan 2019 to Jul 2022 at Beijing Shijitan hospital were retrospectively analyzed.Results:The procedure was successful in all patients. The median operative time was 120 (90, 120) min, and the median intraoperative bleeding was 20.0 (10.0, 27.5) ml. No fistula or serious surgical complications were observed in the patients at 1 month postoperatively. Compared with the preoperative period, the patient's weight decreased [(93.22±15.21) kg vs. (69.97±11.06) kg, t=21.707, P<0.01], BMI decreased [(33.11±4.09) kg/m 2vs. (24.86±2.95) kg/m 2, t=23.224, P<0.01], and the patient's fasting glucose level decreased [9.52 (7.57, 12.96) mmol/L vs. 5.47 (4.66, 6.39) mmol/L, Z=6.11, P<0.01]. The remission rate of various obesity comorbidities was greatly improved. Conclusion:Under the condition of three-incision laparoscopy, the pure manual duodenal and jejunal double-layer suture method is safe, feasible, and effective for patients with obesity combined with type 2 diabetes mellitus.

Objective To investigate the mechanism of fisetin inhibiting the activation of microglia NOD-like receptor family protein 3(NLRP3)inflammasome in microglia and alleviating cognitive impairment after sepsis.Methods C57BL/6 mice were used to establish the sepsis model by cecal ligation and puncture.Mice were divided into four groups:the sham group,the sepsis group,the sepsis+caspase-1 knockout group(sepsis+Cas-1-/-group)and the sepsis+fisetin group.Evans blue was used to detect the permeability of blood-brain barrier(BBB).Morris water maze was used to evaluate the cognitive function of mice.Western blot assay and immunofluorescence double staining were used to detect the expression of NLRP3 inflammasome-related proteins including caspase-1,N-terminal fragment of the GSDMD(GSDMD-N),interleukin(IL)-1β,IL-18 and mitophagy-related proteins(Pink1,Parkin and LC3-Ⅱ)in brain tissue and microglia.Results Compared with the sham group,expression levels of caspase-1,GSDMD-N,IL-1β and IL-18 were significantly increased in the sepsis group(P＜0.05).Compared with the sepsis group,expression levels of caspase-1,GSDMD-N,IL-1β and IL-18 were significantly decreased in the sepsis+Cas-1-/-group(P＜0.05).The expression levels of Pink1,Parkin and LC3-Ⅱ were significantly higher in the sepsis+fisetin group than those of the sepsis group(P＜0.05),and expression levels of caspase-1,GSDMD-N,IL-1β and IL-18 were significantly lower(P＜0.05).After fisetin intervention,the permeability of BBB was decreased and the cognitive impairment(decreased escape latency and increased frequencies of crossing the platform)was alleviated in the sepsis+fisetin group compared with those of the sepsis group(P＜0.05).Conclusion Fisetin may alleviate central inflammation and cognitive impairment after sepsis by inhibiting the activation of microglial NLRP3 inflammasome through activating mitophagy.

Objective To investigate the value of three-dimensional amide proton transfer(3D APT)imaging and multi-model diffusion weighted imaging(DWI)in evaluating the histological grade of cervical squamous cell carcinoma(CSCC).Methods A total of 54 patients with CSCC at different grades were prospectively included.All subjects underwent pelvic 3D APT and multi-b-value DWI sequences on a 3.0T MR scanner.Two radiologists blindly measured the amide proton transfer(APT)values of all continuous layers of the lesion,the apparent diffusion coefficient(ADC)of the mono-exponential-model of DWI,the ture-diffusion coefficient(D),pseudo-diffusion coefficient(D*),perfusion fraction(f)of intravoxel incoherent motion(IVIM)imaging,and the mean diffusivity(MD)and mean diffusion kurtosis(MK)values of diffusion kurtosis imaging(DKI).The receiver operating characteristic(ROC)curve was used to analyze the efficacy of each parameter in identifying different pathological grades of CSCC.Results The APT mean signal intensity(SImean),APT maximum signal intensity(SImax)and maximum mean diffusion kurtosis(MKmax)values of the high-grade group were statistically higher than those of the low-grade group,and the minimum apparent diffusion coefficient(ADCmin),minimum ture-diffusion coefficient(Dmin),and minimum mean diffusivity(MDmin)values were statistically lower than those of the low-grade group(P＜0.05).The area under the curve(AUC)increased after the combination of APT parameters and DWI parameters,which was obviously higher than that of a single parameter(P＜0.05).Conclusion Both APT and multi-model DWI are helpful to identify the degree of differentiation of CSCC,and the diagnostic value of combining the two is higher.

The consensus has been reached on the benefits of surgical drainage. However, catheter-related blockage and retrograde infection remain bottleneck problems in the treatment process. To this end, with Huashan Hospital, Fudan University, as the main inventors, a drainage tube dredging umbrella and anti-retrograde infection kit have been designed and applied for the national utility model patent (patent number: ZL 2023 2 1300036.2). The main body of the kit consists of a catheter dredging umbrella, drainage tube, and drainage bag. Several isolation layers are installed in the drainage bag to form a maze structure and a reflux valve is added, thereby increasing the distance and resistance of liquid reflux, greatly reducing the possibility of liquid reflux entering the drainage tube, so as to reduce the risk of retrograde infection through physical means. When the drainage tube is blocked, the drainage tube and joint tube of the drainage bag can be separated, the unblocking umbrella can be inserted into the blockage through the guide wire, the cannula can be inserted along the guide wire, the guide wire is pulled to release the dredging umbrella in the contraction state, and the dredging umbrella can be pulled back in the expansion state until the blockage is removed from the drainage tube. The operating procedure is standardized and simple. While preventing retrograde infection (anti-retrograde infection kit), the catheter dredging umbrella could effectively address the issue of catheter blockage. It has certain clinical promotion and application value.
