Objective To explore the current situation of disease perception in patients with tophi and its correlation with the quality of life. Methods A retrospective analysis was conducted on 303 gout patients admitted to the Shanghai Sixth People's Hospital from January 2023 to December 2024. The patients were classified into tophi gout (n=150) and non-tophi gout (n=153) groups based on whether they were tophi gout or not. The current disease perception status and quality of life of the two groups were compared using Simplified Chinese Version of the Disease Cognition Questionnaire (BIPQ) and Short Form of Health Survey (SF-36). Logistic regression was used to analyze the influencing factors of the quality of life of patients with tophi gout. Results Compared with the non-tophaceous gout group, the tophaceous gout group had a higher BIPQ score, and a lower SF-36 score (P<0.05). Among patients with tophaceous gout, 80 cases had good quality of life, and 70 cases had poor quality of life. These patients were included in the good quality of life group (n=80) and the poor quality of life group (n=70), respectively. Compared with the good quality of life group, patients in the poor quality of life group had longer gout course and average duration of each gout attack, as well as higher 20-item tophi impact questionnaire (TIQ-20) score and BIPQ score (P<0.05). Logistic regression analysis showed that the course of gout (OR=1.070, 95% CI: 1.017-1.126, P=0.009), TIQ-20 score (OR=1.048, 95% CI: 1.022-1.075, P<0.001), and BIPQ score (OR=1.055, 95%CI: 1.009-1.104, P=0.019) were risk factors affecting the quality of life in patients with tophaceous gout (P<0.05). Conclusion The course of gout, TIQ-20 score and BIPQ score are risk factors affecting the quality of life of patients with tophi gout.

ObjectiveTo observe the clinical efficacy and safety of Tangning Tongluo tablets in the treatment of nonproliferative diabetic retinopathy （DR）. MethodsFourteen research centers participated in this study， which spanned a time interval from September 2021 to May 2023. A total of 240 patients with nonproliferative DR were included and randomly assigned into an observation group （120 cases） and a control group （120 cases）. The observation group was treated with Tangning Tongluo tablets， and the control group with calcium dobesilate capsules. Both groups were treated for 24 consecutive weeks. The vision， DR progression rate， retinal microhemangioma， hemorrhage area， exudation area， glycosylated hemoglobin （HbA1c） level， and TCM syndrome score were assessed before and after treatment， and the safety was observed. ResultsThe vision changed in both groups after treatment （P<0.05）， and the observation group showed higher best corrected visual acuity （BCVA） than the control group （P<0.05）. The DR progression was slow with similar rates in the two groups. The fundus hemorrhage area and exudation area did not change significantly after treatment in both groups， while the observation group outperformed the control group in reducing the fundus hemorrhage area and exudation area. There was no significant difference in the number of microhemangiomas between the two groups before treatment. After treatment， the number of microhemangiomas decreased in both the observation group （Z=-1.437， P<0.05） and the control group （Z=-2.238， P<0.05）， and it showed no significant difference between the two groups. As the treatment time prolonged， the number of microhemangiomas gradually decreased in both groups. There was no significant difference in the HbA1c level between the two groups before treatment. After treatment， the decline in the HbA1c level showed no significant difference between the two groups. The TCM syndrome score did not have a statistically significant difference between the two groups before treatment. After treatment， neither the TCM syndrome score nor the response rate had significant difference between the two groups. With the extension of the treatment time， both groups showed amelioration of TCM syndrome compared with the baseline. ConclusionTangning Tongluo tablets are safe and effective in the treatment of nonproliferative DR， being capable of improving vision and reducing hemorrhage and exudation in the fundus.

HDAC7, a member of class IIa HDACs, plays a pivotal regulatory role in tumor, immune, fibrosis, and angiogenesis, rendering it a potential therapeutic target. Nevertheless, due to the high similarity in the enzyme active sites of class IIa HDACs, inhibitors encounter challenges in discerning differences among them. Furthermore, the substitution of key residue in the active pocket of class IIa HDACs renders them pseudo-enzymes, leading to a limited impact of enzymatic inhibitors on their function. In this study, proteolysis targeting chimera (PROTAC) technology was employed to develop HDAC7 drugs. We developed an exceedingly selective HDAC7 PROTAC degrader B14 which showcased superior inhibitory effects on cell proliferation compared to TMP269 in various diffuse large B cell lymphoma (DLBCL) and acute myeloid leukemia (AML) cells. Subsequent investigations unveiled that B14 disrupts BCL6 forming a transcriptional inhibition complex by degrading HDAC7, thereby exerting proliferative inhibition in DLBCL. Our study broadened the understanding of the non-enzymatic functions of HDAC7 and underscored the importance of HDAC7 in the treatment of hematologic malignancies, particularly in DLBCL and AML.

Objective:To investigate the risk factors for esophageal varices in patients with liver cirrhosis,to establish a predictive model,and to provide reasonable guidance for the prevention of early esophageal varices in patients with liver cirrhosis.Methods:A retrospective analysis was performed for 1 113 patients with liver cirrhosis who attended the hospitals in Chongqing,China from Decem-ber 2006 to May 2021.Recursive feature elimination(RFE)and four machine learning methods were used for the screening of features,and five machine learning predictive models were established by logistic regression,random forest,support vector machine(SVM),de-cision tree,and eXtreme Gradient Boosting(XGBoost).The receiver operating characteristic(ROC)curve was used to evaluate the per-formance of each model,and the model with the best performance was used to investigate the risk factors for esophageal varices in pa-tients with liver cirrhosis.SHAP plots were used to explain the impact of each risk factor on patients.Results:The XGBoost model showed the best performance in predicting the risk of esophageal varices in patients with liver cirrhosis,with an area under the ROC curve of 0.872(95%CI=0.813-0.918).SHAP plots showed that platelet count,diameter of the portal vein,cholinesterase,albumin,ala-nine aminotransferase,hemoglobin,prothrombin ratio,prothrombin time,and serum total protein were risk factors for esophageal vari-ces in patients with liver cirrhosis.Conclusion:This study shows that the XGBoost predictive model has a relatively high predictive value,and the risk factors obtained by this model have a certain guiding significance for the clinical prevention and treatment of early esophageal varices in patients with liver cirrhosis.

Objective To investigate the effectiveness of a nurse-led surgical wound management model in postoperative wound care for patients undergoing tophi surgery.Methods A total of 52 post-operative tophi surgery patients were randomly divided into control and observation groups,with 26 ca-ses each.The control group received routine postoperative care,while the observation group was man-aged nurse-led surgical wound management model in addition to routine care.Postoperative complica-tion rates,hospitalization duration and costs,quality of life[evaluated by Quality of Life(QOL)],nursing satisfaction,pain intensity[evaluated by Numberic Rating Scale(NRS)],and wound recov-ery[evaluated by Wound Bed Score(WBS)]were compared between the two groups.Results The observation group demonstrated significantly shorter hospitalization duration,lower costs,fewer compli-cations,and higher nursing satisfaction compared to the control group(P＜0.05).Additionally,the ob-servation group exhibited superior QOL scores(after intervention),lower NRS scores(postoperative day 1,3,7),and improved WBS scores(postoperative day 3,7,14)(P＜0.05).Conclusion The nurse-led surgical wound management model enhances postoperative recovery in tophi surgery patients by accelerating wound healing,reducing pain duration and shortening hospitalization time,lowering costs and complication rates,and improving quality of life.

Objective To develop and validate a risk prediction model based on early platelet-related parameters for bronchopulmonary dysplasia(BPD)in neonates admitted to the neonatal intensive care unit(NICU),and to facilitate early identification and intervention in high-risk populations.Methods Clinical data of 291 preterm infants with a gestational age(GA)≤32 weeks or a birth weight(BW)＜1 500 g,admitted to the NICU,were retrospectively analyzed.Out of these,214 cases were selected as the modeling group.This group was further categorized into the BPD group(n=76)and the non-BPD group(n=138),based on whether they required oxygen therapy at 28 days post-birth.Perinatal data,platelet-related parameters and other indicators between the two groups.Univariate and multivariate Logistic regression analyses were conducted to identify BPD risk factors,followed by the construction of a nomogram.An additional cohort of 105 preterm infants with GA≤32 weeks or BW＜1 500 g,were used to validate the model.This cohort was divided into the BPD group(n=43)and the non-BPD(n=62)group.Receiver operating characteristic(ROC)curve and calibration curve were used to internally verify the efficiency of the prediction model.Results The Logistic regression analysis identified GA,BW,Apgar score at 5 minutes≤7,invasive ventilation,platelet count(PLT)and mean platelet volume(MPV)as significant factors in the model(P＜0.05).The constructed nomogram was formulated using R language,and the areas under the ROC curve(AUC)for the three models were 0.908,0.931 and 0.918,respectively(P＜0.05).The verification group was verified by Bootstrap.The calibration curve showed a good fit.The internal validation AUC values of the three models were 0.877,0.890 and 0.886,respectively.Conclusion GA,BW,invasive ventilation,Apgar score at 5 minutes≤7,MPV and PLT are key risk factors for BPD onset.The risk prediction model based on these indicators can effectively predict BPD,providing clinicians with a valuable tool for early detection and intervention in the development of BPD.

OBJECTIVE To study the intervention effects of Wenshen Tongluo Zhitong Recipe(WTZR)on macrophage senes-cence and senile osteoporosis.METHODS The senescent macrophage model was established using hydrogen peroxide(H2 O2)and subsequently divided into four groups:control,model,low-dose drug-treated serum,and high-dose drug-treated serum.β-galactosidase staining,Western blot and qPCR were employed to evaluate the mRNA expression of senescence markers p21 and p53.ROS staining and JC-1 staining were applied to assess mitochondrial function in macrophages.The mRNA levels of Interleukin(IL)-6,IL-10,CD206,and inducible nitric oxide synthase(iNOS)were determined by qPCR analysis.Immunofluorescence was used to evaluate argi-nase(ARG1)and iNOS protein expressions for assessing the impact of drug-containing serum on macrophage polarization.qPCR analy-sis was conducted to measure osteocalcin(OCN),collagen type Ⅰ alpha 1(Col1a1),runt-related transcription factor 2(Runx2)mRNA levels as osteoblast-related markers;ALP staining along with alizarin red staining were performed to evaluate the effect of macrophage conditioned medium treated with drug-containing serum on bone marrow mesenchymal stromal cell(BMSC)osteogenic differentiation.C57BL/6J mice were randomly allocated into four groups:control group,model group,WTZR low-dose group,and WTZR high-dose group.The senile osteoporosis(SOP)mouse model was established by D-galactose.Micro-CT scanning analyzed fe-mur microstructure while HE staining detected pathological changes in femur bone tissue samples collected from each experimental con-dition.Furthermore,Western blot was used to detect the senescence-related molecules p21 and p53 and the osteogenesis-related mark-ers OCN and Runx2,qPCR analysis measured tibial expression levels of senescence-related molecules(p21,p53)as well as macro-phage polarisation-related molecules(IL-6,iNOS,CD206,and IL-10)to assess the effect of this compound on a mouse model simula-ting SOP.RESULTS Following intervention with serum containing WTZR,there was a significant decrease in the number of senes-cent positive cells compared to the model group.Additionally,there was a notable decrease in p21 and p53 mRNA and proteins expres-sion(P＜0.05,P＜0.01,P＜0.001).Furthermore,drug-containing WTZR effectively inhibited ROS production induced by H2 O2 and mitigated mitochondrial membrane potential reduction in macrophages(P＜0.05,P＜0.001).Treatment with drug-containing WTZR re-sulted in down-regulated mRNA expression of M1-related gene iNOS(P＜0.05)while up-regulating mRNA expression of M2-related genes CD163 and CD206(P＜0.05).The drug-containing WTZR significantly reduced fluorescence intensity for iNOS(P＜0.01)while increasing ARG1(P＜0.05)fluorescence intensity.Moreover,conditioned medium from macrophages treated with drug-containing ser-um increased ALP positive cell count(P＜0.01,P＜0.001),alizarin red positive area(P＜0.05),as well as Col1a1,Runx2 and OCN mRNA expression levels(P＜0.05,P＜0.01).The Tb.N,BMD,and BV/TV were significantly higher in the WTZR group compared to the model group(P＜0.05,P＜0.01,P＜0.001);meanwhile,Tb.Sp was notably lower than that observed in the model group(P＜0.05,P＜0.01);bone trabeculae were significantly improved,increased in number and widened.Additionally,the compound could significantly inhibit the D-galactose induced up-regulation of tibial senescence-related genes and proteins p21 and p53(P＜0.05,P＜0.001,P＜0.0001),promote the expression of osteogenesis-related markers OCN and Runx2 protein(P＜0.01,P＜0.0001),promote the down-regulation of M1 related genes IL-6 and iNOS(P＜0.05),and promote the expression of M2 related genes IL-10 and CD206(P＜0.05,P＜0.01).CONCLUSION Wenshen Tongluo Zhitong Recipe may play an anti-osteoporosis effect by inhibiting macrophage senescence and promoting the osteogenic differentiation of BMSC.

Objective:To investigate the impact of rosacea on patients＇ quality of life and mental health, and to analyze variations across different subtypes, gender, sun exposure, smoking status, ethnicity, and educational levels, as well as patients＇ demands for treatment.Methods:It was a cross-sectional study from October 2022 to January 2024, 177 rosacea patients from the Department of Dermatology, the First Affiliated Hospital of Kunming Medical University were surveyed. The cohort comprised 36 males and 141 females, with a median age of 35 (29, 44) years. Data collected through questionnaires included general information, Dermatology Life Quality Index (DLQI), Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), and Patient Need Questionnaire (PNQ). Statistical analysis was conducted on the collected data.Results:The median DLQI score was 10 (3, 15), indicating moderate impact. The median GAD-7 score was 5 (2, 7), suggesting mild anxiety; while the median PHQ-9 score was 6 (2, 9), indicating mild depression. Female patients scored higher in both DLQI and GAD-7 than males ( P<0.05). Papulopustular subtypes had higher DLQI and GAD-7 scores compared to other subtypes ( P<0.01). Patients with lower education levels scored higher in DLQI and GAD-7 than those with higher education ( P<0.01), and non-smokers had higher GAD-7 scores than smokers ( P<0.05). Significant positive correlations were found between DLQI and PHQ-9 ( r=0.39, P<0.01), and DLQI and GAD-7 ( r=0.51, P<0.01), as well as between PHQ-9 and GAD-7 ( r=0.59, P<0.01). Regarding treatment needs, 159 patients (89.8%) expressed a strong desire for a clear diagnosis and treatment plan, and the same number wished for a complete resolution of all skin lesions. Female patients consistently demonstrated significantly stronger demands in all 28 treatment need items (all P<0.05). Conclusions:Rosacea significantly affects patients＇ quality of life and mental health, particularly among females, individuals with papulopustular subtypes, and those with lower education levels. There is a strong demand for definitive diagnostic and therapeutic plans, especially among female patients.
