Objective To explore the changing trend in the disease burden of gout in China from 1990 to 2021, and analyze the incidence, prevalence, and disability-adjusted life years (DALYs) by age and gender, with comparisons to global patterns, and to predict the disease burden of gout in China in 2030. Methods Data from the Global Burden of Disease (GBD) database were used to analyze changes in gout burden. Joinpoint regression was used to estimate the average annual percentage change (AAPC) with 95% confidence intervals (CIs). Comparative analyses were conducted on data from China and the world, and an ARIMA model was used to project China's gout burden in 2030. Results From 1990 to 2021, China's age-standardized incidence rate (ASIR) rose from 122.52 to 151.61/100,000, exceeding the global rise from 93.09 to 109.07/100,000. The age-standardized prevalence rate (ASPR) in China increased from 640.67/100,000 to 810.35/100,000, compared to a global rise from 536.54/100,000 to 653.81/100,000. The age-standardized DALYs rate (ASDR) in China increased from 20.2/100,000 to 25.43/100,000, surpassing the global increase from 16.67/100,000 to 20.21/100,000. AAPCs for ASIR, ASPR, and ASDR in China were 0.70%, 0.77%, and 0.75%, respectively, all higher than global rates. Middle-aged and elderly men faced the highest burden. It was predicted that there will be a decline in China's ASIR and ASPR by 2030, while ASDR will remain stable. Conclusion The disease burden of gout in China has increased significantly, outpacing global trends. Targeted interventions for hyperuricemia, particularly in elderly men, are crucial to reduce the future disease burden.

Receptor-interacting serine/threonine-protein kinase 1 (RIPK1) functions as a key regulator in inflammation and cell death and is involved in mediating a variety of inflammatory or degenerative diseases. A number of allosteric RIPK1 inhibitors (RIPK1i) have been developed, and some of them have already advanced into clinical evaluation. Recently, selective RIPK1i that interact with both the allosteric pocket and the ATP-binding site of RIPK1 have started to emerge. Here, we report the rational development of a new series of type-II RIPK1i based on the rediscovery of a reported but mechanistically atypical RIPK3i. We also describe the structure-guided lead optimization of a potent, selective, and orally bioavailable RIPK1i, 62, which exhibits extraordinary efficacies in mouse models of acute or chronic inflammatory diseases. Collectively, 62 provides a useful tool for evaluating RIPK1 in animal disease models and a promising lead for further drug development.

OBJECTIVE To design and synthesize novel α-naphthylthiol amino acid ester lysine specific demethylase 1(LSD1) inhibitors, evaluate their inhibitory activity with selectivity against LSD1, and explore their binding mechanism through molecular docking and dynamics simulation. METHODS Based on the binding mode of hit compound 3a with LSD1, the α- naphthyl mercapto amino acid ethyl ester small molecule compound were designed by fixing the planar hydrophobic naphthyl ring in the structure, while introducing hydrophilic amino fragment, and they were prepared through a multi-component one-pot cascade reaction. All the compounds were evaluated for their inhibitory activity against LSD1 at concentrations of 5.0 and 1.0 μmol·L–1 using the LSD1 screening platform of research group. The most potent compound was tested for its IC50 value and enzyme selectivity over MAO-A and MAO-B, and its binding mode was investigated through molecular docking and dynamics simulation. RESULTS A total of 13 compounds were obtained, all of which exhibited significant inhibitory effects on LSD1. Among them, nine compounds showed an inhibitory rate of over 50.0% against LSD1 at a concentration of 1.0 μmol·L–1, while compound 3l displaying the best activity with an IC50 value of 0.17 μmol·L–1, 174 times higher than the positive control. It also showed excellent selectivity towards MAO-A and MAO-B. Molecular docking and dynamics simulations indicated that compound 3l inhibited the activity of LSD1 through multiple interactions. CONCLUSION The structures of α-naphthylthiol amino acid ester can serve as lead compounds or active fragments, laying a solid foundation for the subsequent design of LSD1 inhibitors based on structure-oriented drug design.

Objective To explore the characteristics of blood lipid metabolism indicators and risk factors of prognosis in children with systemic lupus erythematosus (SLE). Methods A total of 54 children who were diagnosed with SLE and hospitalized in Chengdu Women and Children’ s Central Hospital from January 2013 to August 2022 were selected. Clinical data of all children were collected and blood lipid metabolism indicators and biochemical indicators were detected , and binary logistic regression was used to analyze the prognosis risk factors in children with SLE. Results Among the 47 cases (87.04%) had abnormal blood lipid metabolism at admission, and is mainly manifested as elevated levels of LDL-C, TG and TC and decreased level of HDL-C. The proportion of cardiovascular system damage, hematological system damage, urinary protein positivity, and SLEDAI-2000 score in the group with good prognosis were lower than those in the group with poor prognosis, while the proportion of dsDNA positivity was higher in the group with poor prognosis. Binary Logistic regression analysis showed that the cardiovascular system damage and positive urinary protein were risk factors for poor prognosis, with statistically significant differences (P<0.05). Conclusion Abnormal blood lipid metabolism is common in children with SLE, and cardiovascular system damage and positive urinary protein may increase the risk of poor prognosis in young children.

Objective:To investigate the association between the Doppler variables of the ophthalmic artery with the severity of preeclampsia(PE).Methods:Systematic literature was searched between January 1995 and March 2023 in PubMed,Web of Science,Embase,and the Cochrane Library.Studies comparing ophthalmic artery Doppler variables,including peak systolic velocity(PSV),end-diastolic velocity(EDV),resistive index(Rl),pulsa-tility index(PI),and peak ratio(PR,the ratio of the flow velocity of the second peak to that of the initial peak)in patients with PE,severe preeclampsia(sPE),and healthy pregnant women were included.The random-effects model was adopted as the method of pooled analysis,and the I2value was used to assess heterogeneity.The pooled standardized mean difference(SMD)with 95％confidence interval(CI)was used to estimate the associa-tion between ophthalmic artery Doppler variables and PE patient's characteristics.Results:Eight retrospective studies were eventually included in this Meta-analysis.Our pooled results suggested that compared with PE ca-ses,sPE patients had lower PI levels(SMD-0.56,95％CI-0.92～-0.20,P=0.000),higher EDV levels(SMD 0.47,95％CI 0.12～0.83,P=0.028)and higher PR levels(SMD0.96,95％CI 0.13～1.78,P=0.023).Howev-er,there was no significant difference between PE and sPE patients about the PSV and RI(P=0.361,P=0.626).Conclusions:This review demonstrates that ophthalmic artery Doppler variables(PI,EDV and PR)could be useful for predicting PE and PE development(especially in identifying sPE),which in turn may help the practitioner in the management of these complicated cases and in taking early necessary precautions.

MethodsA survey was conducted among 93 assessment personnel randomly selected from 29 elderly care needs assessment agencies in Shanghai. The personnel’s perception of their work and their levels of job satisfaction were examined. Chi-square test and Fisher’s precision probability test were used to compare regional differences， while the two-factor theory was employed to analyze the factors influencing job satisfaction. ResultsRegarding perception of the work， 92.5% of the surveyed personnel believed their work was important. Moreover， 87.1% were interested in their assessment tasks， and 84.9% believed they made a positive contribution to the assessment work and the assessment position was in line with their personal preferences. Regarding job satisfaction， 83.9% of the participants were satisfied with their assessment work， 78.5% considered the workload appropriate， and 74.2% found the working hours suitable. Additionally， 65.6% expressed satisfaction with the level of cooperation from the assessment subjects， while 94.6% and 91.4% of the personnel were satisfied with the support provided by the assessment agencies and had a sense of belonging， respectively. Furthermore， 65.6% of the personnel expressed satisfaction with their job compensation and benefits. Hygiene factors affecting job satisfaction included salary and compensation， workload， time spent on the job and institutional support related to external assistance， job suitability， teamwork， and client cooperation （P<0.05）， while motivational factors included recognition of the significance of the job， sense of achievement， interest in the job， sense of belonging， and opportunities for personal growth （P<0.05）. ConclusionThe overall work cognition and satisfaction of unified elderly care needs assessment personnel in Shanghai towards their work are relatively positive. Main issues include the heavy workload and actual job subsidies not meeting expectations. It is recommended to improve the standardization of the assessment process， establish a professional team of assessment personnel， and enhance the compensation and incentive mechanisms to continuously increase staff satisfaction.

ObjectiveTo investigate the structural and functional characteristics of gut microbiota in common traditional Chinese medicine （TCM） syndromes of irritable bowel syndrome with diarrhea （IBS-D）. MethodsIBS-D patients who visited the Hospital of Chengdu University of Traditional Chinese Medicine， and healthy participants from the Physical Examination Centre of the same hospital were recruited from 1st January 2020 to 31st March 2021.The IBS-D patients were classified into syndrome of liver constraint and spleen deficiency， and syndrome of spleen deficiency and dampness exuberance； together with the recruited healthy participants， there were liver-constraint group， dampness-exuberance group， and healthy group. General information， including age， gender and body mass index （BMI）， were collected， and Irritable Bowel Syndrome Symptom Severity Scale （IBS-SSS） as well as Irritable Bowel Syndrome Quality of Life Scale （IBS-QOL） scores were additionally collected from IBS-D patients. Fresh fecal samples were also collected and tested by macro-genome sequencing technology for abundance statistical display， PCoA， Anosim， LEfSe bioinformatic analysis of the annotated gut microbiota structure and function. ResultsThere was no statistically significant difference in the general information of the participants in the three groups （P＞0.05）； the difference in the IBS-SSS and IBS-QOL scores between liver-constraint group and dampness-exuberance group were not statistically significant （P＞0.05）. The study included 28 cases each in liver-constraint group， dampness-exuberance group， and healthy group. The number of specific genes to patients in liver-constraint group was 269 135， with 216 156 in dampness-exuberance group and 249 759 in healthy group， accounting of total 1 784 036 in the three groups. There were differences in the relative abundance distribution of the top ten species of gut microbiota among the three groups， with smaller differences at the phylum， class and order levels， and larger differences at the family， genus and species levels. There were differences in the relative abundance of structure and function of the gut microbiota among the three groups. Species PCoA and Anosim analyses at the species level showed significant differences in the composition of the microbiota among the three groups. Further LEfSe analyses showed that patients in liver-constraint group were screened for 14 dominant strains， of which Clostridium sp. CAG 217， Lachnospira pectinoschiza， Anaerotruncus sp. CAG 528， Paeniclostridium sordellii， Eubecterium sp. CAG 76， Bacillus cereus were affected to a greater extent in abundance differences； dampness-exuberance group screened 24 species of dominant bacteria， of which Roseburia inulinivorans， Eubacterium sp. CAG 251， Roseburia hominis， Unclassified Eubacterium rectale， Roseburia intestinalis， and Megamonas funiformis were affected to a greater extent in abundance differences； no dominant functional genes were screened for patients in liver-constraint group， and dampness-exuberance group was screened for flagellum assembly （ko02040）， porphyrin metabolism （ ko00860）， salmonella infection （ko05132）， and benzoic acid degradation （ko00362）. The differentially dominant functional genes in liver-constraint group and dampness-exuberance group may mainly focus on metabolism （including biodegradation and metabolism of exogenous substances， energy metabolism， lipid metabolism， etc.）. ConclusionIBS-D with syndrome of liver constraint and spleen deficiency is characterized by the enrichment of 14 gut microbiota， such as Clostridium sp. CAG 217， while IBS-D with syndrome of spleen deficiency and dampness exuberance is characterized by the enrichment of 24 gut microbiota， such as Roseburia inulinivorans， and 4 functional enrichments， such as flagellum assembly. Clostridium sp. CAG 217 and Roseburia inulinivorans are expected to be biomarkers for IBS-D patients in the two syndromes， respectively.

Objective:To explore the application value of posture adaptation training combined with continuous pas-sive exercise rehabilitation for patients after coronary artery bypass grafting(CABG).Methods:A total of 100 pa-tients with coronary heart disease(CHD)undergoing CABG in our hospital were enrolled,divided into single group(n=50,received single continuous passive exercise rehabilitation intervention)and combined group(n=50,re-ceived posture adaptation training based on single group)according to color grouping method.Both groups were in-tervened for two months.Clinical indexes,cardiac function indexes,cognitive function,exercise endurance,serum levels of neuron specific enolase(NSE),S-100β protein and satisfaction were analyzed and compared between two groups.Results:Compared with single group after intervention,there were significant reductions in first out of bed time,first anal exhaust time and length of hospital stay,and significant rise in left ventricular ejection fraction(LVEF),cardiac index(CI),left ventricular fractional shortening(LVFS),score of Montreal cognitive assessment(MoCA)scale,6min walking distance,and significant reductions in serum levels of NSE[(19.93±1.90)μg/L vs.(16.59±2.25)μg/L]and S-100β protein[(6.72±0.34)μg/L vs.(3.96±0.19)μg/L]in combined group,P=0.001 all.Satisfaction in combined group was significantly higher than that of single group(94.00％vs.80.00％,P=0.037).Conclusion:Posture adaptation training combined with continuous passive exercise rehabilitation can sig-nificantly improve the clinical indexes,promote cardiopulmonary function and cognitive function recovery in pa-tients undergoing coronary artery bypass grafting after operation.

Objective To investigate the attributable risk(AR)of Acinetobacter baumannii(AB)infection in criti-cally ill patients.Methods A multicenter retrospective cohort study was conducted among adult patients in inten-sive care unit(ICU).Patients with AB isolated from sterile body fluid and confirmed with AB infection in each cen-ter were selected as the infected group.According to the matching criteria that patients should be from the same pe-riod,in the same ICU,as well as with similar APACHE Ⅱ score(±5 points)and primary diagnosis,patients who did not infect with AB were selected as the non-infected group in a 1:2 ratio.The AR was calculated.Results The in-hospital mortality of patients with AB infection in sterile body fluid was 33.3％,and that of non-infected group was 23.1％,with no statistically significant difference between the two groups(P=0.069).The AR was 10.2％(95％CI:-2.3％-22.8％).There is no statistically significant difference in mortality between non-infected pa-tients and infected patients from whose blood,cerebrospinal fluid and other specimen sources AB were isolated(P＞0.05).After infected with AB,critically ill patients with the major diagnosis of pulmonary infection had the high-est AR.There was no statistically significant difference in mortality between patients in the infected and non-infec-ted groups(P＞0.05),or between other diagnostic classifications.Conclusion The prognosis of AB infection in critically ill patients is highly overestimated,but active healthcare-associated infection control for AB in the ICU should still be carried out.
