Objective To observe and analyze the clinical efficacy of Hewei Jiangni Formula in treating patients with non-erosive gastroesophageal reflux disease(NERD)and cold-heat complex syndrome and explore its regulatory mechanism on visceral hypersensitivity.Methods Sixty patients with NERD and cold-heat complex syndrome diagnosed at the Gastroenterology Clinic of Dongfang Hospital,Beijing University of Chinese Medicine from January 2021 to Decemer 2023,were randomly divided into the Hewei Jiangni Formula group and omeprazole group,with 30 patients per group.The Hewei Jiangni Formula group was treated with Hewei Jiangni Formula and omeprazole enteric-coated tablets placebo,whereas the omeprazole group was treated with omeprazole enteric-coated tablets and Hewei Jiangni Formula placebo.The treatment period was scheduled to last for 8 weeks.The primary outcome indicators(Gastroesophageal Reflux Disease Quality of Life Questionnaire(GERD-Q)scale score:response rate,total score,and single symptom score)and secondary outcome indicators(traditional Chinese medicine clinical scores scale)were recorded before and after treatment in both groups.Ten healthy individuals were recruited from the Physical Examination Center of Dongfang Hospital,Beijing University of Chinese Medicine,as the healthy control group.The expression levels of mast cell tryptase(MCT),protease-activated receptor 2(PAR2),transient receptor potential vanilloid 1(TRPV1),substance P(SP),calcitonin gene-related peptide(CGRP),5-hydroxytryptamine(5-HT),and 5-hydroxytryptamine 3 receptor(5-HT3R)were recorded.These indicators were then used for the following comparisons:the NERD patients vs.the healthy group before treatment;the Hewei Jiangni Formula group vs.the omeprazole group after treatment;the intra-group comparisons within both NERD groups.Changes in serum levels of these indicators were observed before and after treatment in both NERD groups.Results According to the GERD-Q scores before and after treatment,the effective rate was 90.00%in the Hewei Jiangni Formula group and 86.67%in the omeprazole group,with no significant differences.Both groups exhibited improved symptoms of heartburn,regurgitation,upper abdominal pain,and sleep disorders caused by heartburn or regurgitation(P<0.05);however,neither group exhibited significantly improved nausea(P>0.05).Before treatment,MCT,PAR2,TRPV1,SP,CGRP,5-HT,and 5-HT3R expression levels in both NERD groups were significantly higher than those in the healthy control group(P<0.05).After treatment with Hewei Jiangni Formula or omeprazole enteric-coated tablets,the expression levels of these indicators decreased in both groups(P<0.05).The omeprazole group was superior to Hewei Jiangni Formula in reducing 5-HT3R expression(P<0.05).Conclusion Hewei Jiangni Formula significantly improves the symptoms of patients with NERD and cold-heat complex syndrome,with efficacy comparable to that of omeprazole enteric-coated tablets.It is superior to omeprazole in improving symptoms of spleen yang deficiency,such as loss of appetite,fatigue,borborygmus with loose stools,and cold extremities.Hewei Jiangni Formula reduces MCT,PAR2,TRPV1,SP,CGRP,5-HT,and 5-HT3R expression levels,regulates related signaling pathways,and alleviates visceral hypersensitivity.

Objective:To investigate the role and underlying mechanism of protein arginine methyltransferase 1 (PRMT1) and its inhibitor in alkali burn-induced corneal neovascularization (CNV).Methods:Seventy-two SPF-grade C57BL/6 mice were randomly divided into a normal group and 1 day post-modeling, 4 days post-modeling, and 7 days post-modeling groups to establish an alkali burn-induced CNV model and determine the optimal time point for analysis.Another 90 mice were randomly assigned to five groups: alkali burn group, dimethyl sulfoxide (DMSO) group, PRMT1 inhibitor group, fibroblast growth factor 2 (FGF2) inhibitor group, and PRMT1 inhibitor combined with FGF2 group to evaluate the role of PRMT1 in CNV.Human umbilical vein endothelial cells (HUVECs) and murine macrophage-like RAW264.7 cells were used to establish a hypoxia/reoxygenation (H/R)-induced in vitro model to mimic the ischemic microenvironment.Cells were assigned to the following groups: control group, H/R group, H/R+ DMSO group, H/R+ si-NC group, H/R+ si-PRMT1 group, H/R+ si-FGF2 group, H/R+ PRMT1 inhibitor group, and H/R+ PRMT1 inhibitor+ FGF2 group.Corneal opacity and CNV areas were assessed by slit-lamp microscopy.Corneal structural changes and inflammatory cell count were determined by hematoxylin and eosin staining.PRMT1-positive cell count was determined by immunohistochemistry and the expression of PRMT1, CD31, vascular endothelial growth factor (VEGF), F4/80, CD206, and inducible nitric oxide synthase (iNOS) was assessed by immunofluorescence staining.The expression levels of macrophage markers, including F4/80, iNOS, CD206, interleukin-10 (IL-10), and arginase-1 (Arg-1), were quantified by real-time quantitative PCR and Western blot.Cell proliferation, migration, and angiogenic capacity were evaluated by functional assays including the CCK-8 assay, wound healing assay, Transwell migration assay, and tube formation assay.The research process followed the relevant regulations of the Visual and Ophthalmology Association, and the research plan was approved by the Laboratory Animal Committee of Wuhan University (No.20220504A). Results:Compared with the normal group, the 7 days post-modeling group showed significantly increased corneal opacity scores and CNV area, upregulated VEGF expression, and increased inflammatory cells (all P<0.05).The number of PRMT1-positive cells in the alkali burn group was (39.67±3.51) cells/visual field, which was significantly higher than (3.33±0.58) cells/visual field in the normal group ( t=17.68, P<0.01).Both mRNA and protein expression levels of PRMT1 and FGF2 were significantly elevated in the alkali burn group compared with the normal group (all P<0.01).Compared with the alkali burn group, the PRMT1 inhibitor group showed reduced corneal opacity scores, decreased CNV area, fewer inflammatory cells, and lower expression levels of PRMT1, FGF2, VEGF, Arg-1, IL-10 proteins, as well as CD206 mRNA (all P<0.05).Cell viability, migration distance, migration number, and tubes formed were significantly increased in the H/R group compared with the control group, significantly reduced in the H/R+ si-PRMT1 and H/R+ PRMT1 inhibitor groups compared with the H/R group and significantly increased in H/R+ PRMT1 inhibitor+ FGF2 group than in H/R+ PRMT1 inhibitor group (all P<0.05).Compared with the H/R group, the H/R+ PRMT1 inhibitor group exhibited reduced expression of FGF2, VEGFA, p-PI3K, and p-Akt, while those were upregulated in the H/R+ PRMT1 inhibitor+ FGF2 group compared with the H/R+ PRMT1 inhibitor group (all P<0.05).The proportions of CD206-positive cells in the H/R, H/R+ DMSO, H/R+ PRMT1 inhibitor, and H/R+ PRMT1 inhibitor+ FGF2 groups were all significantly higher than those in the control group, and significantly higher in the H/R, H/R+ DMSO, and H/R+ PRMT1 inhibitor+ FGF2 groups compared with the H/R+ PRMT1 inhibitor group (all P<0.05).Compared with the alkali burn group, the FGF2 inhibitor group, PRMT1 inhibitor group, and PRMT1 inhibitor+ FGF2 group all showed reduced corneal opacity scores, CNV area, and decreased number of VEGFA-, CD206-, and F4/80-positive cells, with the above indicators being lower in the PRMT1 inhibitor group compared with the FGF2 inhibitor and PRMT1 inhibitor+ FGF2 groups and higher in PRMT1 inhibitor+ FGF2 group than in the FGF2 inhibitor group (all P<0.05).Compared with the alkali burn group, the PRMT1 inhibitor group had decreased protein expression levels of FGF2, p-PI3K, p-Akt, CD31, VEGFA and Arg-1, with higher protein expression levels in the PRMT1 inhibitor+ FGF2 group than in the PRMT1 inhibitor group (all P<0.05). Conclusions:PRMT1 may regulate macrophage activation and anti-inflammatory polarization via the FGF2/PI3K/Akt signaling pathway, thereby promoting the occurrence and development of CNV.Targeted inhibition of PRMT1 may serve as an effective therapeutic strategy for CNV.

Perioperative rehabilitation aims to alleviate symptoms,restore function,and improve quality of life.These goals largely involve subjective patient experiences,which are not fully captured by traditional outcome measures.In recent years,patient-reported outcomes(PROs)have emerged as essential tools to quantify patients'perceptions of health and have been widely used in drug and device clinical trials.This review summarizes the current applications of PROs in general surgery,including symptom description,comparison of surgical methods,complication warning,and patient management.Practical cases and evidence from domestic and international studies are discussed.With the integration of electronic PROs(ePROs),artificial intelligence,and natural language processing,future efforts should focus on developing localized,specialty-specific tools and establishing stronger correlations between PROs and clinical outcomes to support the transition from disease-centered to patient-centered surgical care.

BACKGROUND:Previous studies have confirmed that Wen-Shen-Tong-Du Decoction can promote the recovery of spinal cord injury by inhibiting pyroptosis of splenic B cells,promoting the phagocytosis of myelin debris by microvascular endothelial cells,affecting the migration and infiltration of microglia,promoting the recovery of damaged neurons,and decreasing neuronal apoptosis after spinal cord injury,but the mechanism of this is still not clear. OBJECTIVE:To investigate the effect of Wen-Shen-Tong-Du Decoction on the triggering receptor expressed on myeloid cells 2(TREM2)and PI3K/Akt signaling pathways in mice following spinal cord injury. METHODS:Thirty-six C57BL/6 mice were selected and randomly divided into a sham-operation group,a model group and a Wen-Shen-Tong-Du Decoction group,with 12 mice in each group.In the model and Wen-Shen-Tong-Du Decoction groups,mouse models of T10 spinal cord injury were prepared by the modified Allen's method.On the 1st day after modeling,the Wen-Shen-Tong-Du Decoction group was given Wen-Shen-Tong-Du Decoction by gavage,and the sham-operation group and the model group were given saline by gavage once a day for 28 days.During the drug administration period,mouse motor function was evaluated by Basso Mouse Scale score and inclined plane test.On the 7th and 28th days after modeling,hematoxylin-eosin staining was used to observe the histopathological changes in the spinal cord tissue of the mice;immunofluorescence double staining was used to detect the protein expression of ionized calcium binding adaptor molecule 1(IBA1)and TREM2;and western blot assay was used to detect the expression of TREM2,PI3K,p-PI3K,Akt,p-Akt,Bcl2,Bax and Caspase3 in spinal cord tissue. RESULTS AND CONCLUSION:Basso Mouse Scale scores and inclined plane test results indicated that the motor function of the mouse hindlimbs was declined after spinal cord injury,and Wen-Shen-Tong-Du Decoction significantly improved motor function in mice with spinal cord injury.Hematoxylin-eosin staining results revealed that Wen-Shen-Tong-Du Decoction significantly ameliorated the pathological structure of spinal cord tissue compared with the model group,manifesting as reduced degrees of dorsal white matter and neuronal atrophy,decreased cytoplasmic vacuolization,and reduced inflammatory cell infiltration.Immunofluorescence double staining results showed that on the 7th day after modeling,the protein expression of IBA1 and TREM2 in the model group was lower than that in the sham-operation group(P＜0.05),and the protein expression of IBA1 and TREM2 in the Wen-Shen-Tong-Du Decoction group was higher than that in the model group(P＜0.05);on the 28th day after modeling,the protein expression of TREM2 in the model group was lower than that in the sham-operation group(P＜0.05),and the protein expression of TREM2 in the spinal cord tissue of the mice in the Wen-Shen-Tong-Du Decoction group was higher than that in the model group(P＜0.05).Western blot results analysis demonstrated that on the 7th day after modeling,compared with the sham-operation group,the model group exhibited a significant reduction in TREM2,PI3K,and Bcl2/Bax(P＜0.05),as well as a significant increase in p-Akt,Bax and p-Akt/Aktp-PI3K(P＜0.05);compared with the model group,the Wen-Shen-Tong-Du Decoction group showed a significant increase in TREM2,PI3K,p-PI3K,Akt,p-Akt,Bcl2,p-PI3K/PI3K,p-Akt/Ak,and Bcl2/Bax(P＜0.05),as well as a significant decrease in Bax and Caspase3 protein expression(P＜0.05).On the 28th day after modeling,compared with the sham-operation group,the model group exhibited a significant reduction in TREM2,PI3K,p-PI3K,Akt,p-Akt,Bcl2 and Bcl2/Bax(P＜0.05),as well as a significant increase in Bax protein expression(P＜0.05);compared with the model group,the Wen-Shen-Tong-Du Decoction group showed a significant increase in TREM2,PI3K,Akt,p-Akt,Bcl2,and Bcl2/Bax(P＜0.05),as well as a significant decrease in Bax protein expression(P＜0.05).To conclude,Wen-Shen-Tong-Du Decoction may activate the PI3K/Akt signaling pathway by up-regulating the expression of TREM2 protein in microglia,and then inhibit neuronal apoptosis,thus exerting neuroprotective effects and promoting the repair of spinal cord injury.

Objective To construct a comprehensive evaluation model for physician promotion in tertiary hospitals,which is systematic,scientific and operational.Methods Based on the physician competency model,a multi-level evaluation index system was constructed through literature review,policy analysis,and Delphi method.A simulation assessment was conducted using the CRITIC-TOPSIS method on 22 clinical physicians from a tertiary general hospital in Sichuan Province.Results The final evaluation model,established after two rounds of Delphi consultation,consisted of 4 first-level indicators,10 second-level indicators and 33 third-level indicators.The expert authority coefficient was 0.776,and the Kendall's W coefficients for the two rounds were 0.386 and 0.348(P＜0.01),respectively.The weights for clinical practice,teaching,research,and ethical conduct were 49.44%,18.82%,20.13%,and 11.61%,respectively.Simulation score results show that,the average relative proximity values of case physicians to be promoted to senior,associate senior,and intermediate titles were 0.50,0.43,and 0.39,respectively.Conclusion The model demonstrates scientific validity and reliability for evaluating physician promotion to intermediate and senior professional titles.Five supporting recommendations are proposed:talent development,standard optimization,health information system management,communication and feedback mechanism,and performance enhancement.

Objective:To construct a nanoparticle vaccine displaying the prefusion F (preF) protein of respiratory syncytial virus (RSV) using the I53-50 protein nanoparticle platform, and to systematically evaluate its immunogenicity and protective efficacy.Methods:The RSV preF trimer antigen was genetically fused to I53-50A and assembled in vitro with I53-50B to form preF-I53-50 nanoparticles, theoretically displaying 20 preF antigens per particle. The structure and purity were characterized by size-exclusion chromatography, SDS-PAGE, and negative-stain electron microscopy. BALB/c mice were intramuscularly immunized with varying doses (1 μg or 5 μg) of preF antigen or an equimolar amount of preF-I53-50 nanoparticles. Humoral immunity, B-cell responses, and protective efficacy were assessed following intranasal viral challenge.Results:The preF-I53-50 nanoparticles self-assembled into spherical structures (50-60 nm in diameter) with uniformly arrayed antigens. The nanoparticle vaccine enhanced RSV-specific IgG1 and IgG2a antibody responses, promoting a Th1-biased immune profile. At equimolar preF doses, the neutralizing antibody titers induced by 1 μg and 5 μg nanoparticle formulations were 2.8-fold and 2.3-fold higher, respectively, than those elicited by preF alone ( P<0.05). Notably, even the low-dose nanoparticle group outperformed the high-dose preF group (1.6-fold increase). Viral challenge experiments demonstrated that preF-I53-50 effectively suppressed pulmonary viral replication, mitigated pathological damage, and induced stronger germinal center and memory B-cell responses, suggesting enhanced B-cell affinity maturation and long-term immune memory. Conclusion:The preF-I53-50 vaccine improves the immunogenicity and protective efficacy of RSV preF through multivalent antigen display.

OpenSim is an open source, free motion simulation and gait analysis software, which can be used to dynamically simulate and analyze the complex motion of the human body, and is widely used in human biomechanical research. Since OpenSim can analyze multi-dimensional motion data such as muscle strength, joint torque, and muscle synergistic activation during human movement, it can be used to study the biomechanical mechanism of musculoskeletal imbalance diseases and various treatment methods in TCM orthopedics, and has a broad application prospect in the field of TCM orthopedics. By the analysis of the basic characteristics, elements, analysis process, and application prospects of OpenSim, it is concluded that OpenSim musculoskeletal model has a large application space in the field of traditional Chinese medicine orthopedic, which is helpful to explain the pathogenesis and mechanism of diseases, and promote the precision diagnosis and treatment of orthopedics diseases;the application of OpenSim musculoskeletal model can solve the problem that the previous research paid attention to the bone malalignment and not enough attention to the tendon, and provide a new method for the research of orthopedic diseases. At present, there are still problems in the promotion and application of OpenSim, such as large equipment requirements and high operation threshold. Therefore, multidisciplinary cooperation, clinical research, and data sharing are the basic research strategies in this field.
