The aim of this updated guideline is to provide comprehensive recommendations for the management of gout in patients with common comorbidities, such as chronic kidney disease(CKD), cardiovascular disease(CVD), diabetes, osteoarthritis(OA), and gastrointestinal disorders. This guideline was developed by a multidisciplinary expert panel consisting of specialists in endocrinology, rheumatology, nephrology, cardiology, gastroenterology, and methodology. The development process adhered to standard methodologies, including PICO(population, intervention, comparator, and outcomes) question deconstruction, systematic literature review, the Grading of Recommendations Assessment, Development and Evaluation(GRADE) for evidence and recommendation evaluation, Delphi voting, and expert consensus. The guideline presents 26 evidence-based recommendations addressing 7 clinical questions for patients with hyperuricemia and gout in the context of comorbidities. Key recommendations include the maintenance of strict serum urate targets, particularly for patients with CKD stage≥3, chronic gouty arthritis, and OA, in order to prevent disease progression. In patients with CVD or diabetes, intra-articular triamcinolone is preferred over systemic glucocorticoids. Prioritized anti-inflammatory treatments for patients with CKD, gastrointestinal diseases and OA are recommended. The guideline also introduces emerging therapies, such as interleukin-1 inhibitors and selective urate transport inhibitors, as potential treatment options for refractory cases. The update offers a comprehensive, patient-centered approach to managing gout, particularly in individuals with associated comorbidities. Multidisciplinary collaboration and emerging new treatments and evidence ensure the optimization of the recommendations.

Objective: To investigate the exposure to television advertising of sugar sweetened beverages and the use of persuasive marketing techniques among children and adolescents in Beijing, so as to provide evidence for reduing childrens intake of sugar sweetened beverages. Methods: From October 19, 2020 to November 16, 2021, 32 days were randomly selected. The top four popular channels of children and adolescents aged 3-18 years were defined. Each channel was monitored from 6:00:00 to 23:59:59 for each date. A total of 2 304 h was recorded. Advertisements involving sugar sweetened beverages broadcast before, during or after the program were included. The frequency and the use of persuasive marketing techniques were analyzed. Results: A total of 1 237 advertisements for sugar sweetened beverages were included, of which 50.93% were dairy beverages, 28.38% were teabased beverages, and 19.48% were vegetable protein beverages. The average frequency of sugar sweetened beverages advertisements on every channel was (0.62±1.29)piece/h. The frequency of sugar sweetened beverages advertisements on every local channel [(1.04±1.35)piece/h] and childrens channel [(1.11±1.61)piece/h] was separately higher than every national channel [(0.48±1.24)piece/h] and general channel [(0.12±0.48)piece/h] (t=-14.05, 31.64, P<0.01). There were seasonal differences in television advertising of sugar sweetened beverages, and were more frequent during lunch and dinner times. The most frequently used persuasive marketing techniques were "images of children" (74.54%), "nutritional message" (61.76%), "product composition details" (58.61%), "nutrition claim" (57.24%), and "nutrition function claim or other function claim" (53.11%). Conclusions Children and adolescents are often exposed to television advertisement of sugar sweetened beverages on childrens channels and during meal times. There is an urgent need to formulate relevant policies to regulate the marketing of sugar sweetened beverages advertisement and reduce children and adolescents intake.

Based on high-resolution magnetic resonance tube wall imaging,reverse medical engineering modeling techniques are used to obtain individualized intracranial artery models of high prevalence in ischemic stroke.Three types of intracranial artery models,including Newtonian fluid model,non-Newtonian fluid model and non-Newtonian fluid with two-phase flow model,are established for transient numerical simulations using computational fluid dynamics method.The hemodynamic parameters such as blood flow field,wall shear stress distribution and erythrocyte volume distribution are analyzed to investigate the possible mechanisms involved in the formation and progression of intracranial atherosclerosis.It is found that blood flow velocity increased significantly at the end of the internal carotid artery and the middle cerebral artery.Low-speed vortex flow and disturbed flow appear in the local vessels.The difference in blood flow velocity between the center and the edge of the wall is large,with an obvious low-flow velocity area on the outer side.A clear central core area is formed in the stenotic wall under the action of high-speed blood flow,resulting in thinner edge layer and lower erythrocyte volume fraction.The combination of low erythrocyte distribution in the edge layer and low flow velocity on the outer side of the wall exacerbates endothelial cell necrosis,hypoxia,endothelial dysfunction,and leads to atherosclerosis.Compared with Newtonian and non-Newtonian fluid models,non-Newtonian fluid with two-phase flow model has greater variability for hemodynamic parameters and shows higher fidelity in simulating blood flow,which provides a reference for clinical diagnosis and treatment of cerebrovascular diseases.

Objective To elucidate the regulatory effects of Glycerol Kinase(GLPK)on the inflammatory response induced by lipopolysaccharide(LPS)in mouse Raw264.7 macrophages.Methods Raw264.7 macrophages were cultured in vitro,and an inflammatory model was established through LPS induction.The transcriptional levels of inflammatory cytokines NF-κB,TNF-α,IL-6,and IL-1β were quantified using RT-qPCR.The expression and localization of GLPK were examined via Western blot and immunofluorescence.Additionally,Western blot analysis was employed to detect the levels of cellular pan-succinylation and H3K23su expression.ChIP-qPCR was utilized to assess the enrichment of H3K23su modification at the IL-10 promoter.The total reactive oxygen species production was measured using DCFH-DA probes,while mitochondrial ROS levels were determined with Mito-SOX probes.Mitochondrial membrane potential changes,indicative of mitochondrial dysfunction,were evaluated using JC-1 fluorescent probes.Furthermore,GLPK overexpression plasmids were transfected into cells to investigate the effects of GLPK on inflammatory responses,mitochondrial function,and epigenetic modifications.Results LPS treatment led to mitochondrial dysfunction,inflammatory responses exacerbation,succinylation modifications reduction,and GLPK protein expression decrease in Raw264.7 cells.Overexpression of GLPK in LPS-treated cells improved mitochondrial function and reduced the transcription of pro-inflammatory cytokines.ChIP-qPCR analysis revealed that GLPK overexpression could reverse the LPS-induced suppression of H3K23su modification at the IL-10 promoter,thereby attenuating the inflammatory response.Conclusion LPS mediates inflammatory responses in Raw264.7 macrophages through a GLPK-dependent H3K23 succinylation modification mechanism.

Objective:To compare the differences in the prevalence of mild micro-hepatic encephalopathy (MHE) among patients with cirrhosis by using the psychometric hepatic encephalopathy score (PHES) and the Stroop smartphone application (Encephal App) test.Methods:This prospective, multi-center, real-world study was initiated by the National Clinical Medical Research Center for Infectious Diseases and the Portal Hypertension Alliance and registered with International ClinicalTrials.gov (NCT05140837). 354 cases of cirrhosis were enrolled in 19 hospitals across the country. PHES (including digital connection tests A and B, digital symbol tests, trajectory drawing tests, and serial management tests) and the Stroop test were conducted in all of them. PHES was differentiated using standard diagnostic criteria established by the two studies in China and South Korea. The Stroop test was evaluated based on the criteria of the research and development team. The impact of different diagnostic standards or methods on the incidence of MHE in patients with cirrhosis was analyzed. Data between groups were differentiated using the t-test, Mann-Whitney U test, and χ2 test. A kappa test was used to compare the consistency between groups. Results:After PHES, the prevalence of MHE among 354 cases of cirrhosis was 78.53% and 15.25%, respectively, based on Chinese research standards and Korean research normal value standards. However, the prevalence of MHE was 56.78% based on the Stroop test, and the differences in pairwise comparisons among the three groups were statistically significant (kappa = -0.064, P < 0.001). Stratified analysis revealed that the MHE prevalence in three groups of patients with Child-Pugh classes A, B, and C was 74.14%, 83.33%, and 88.24%, respectively, according to the normal value standards of Chinese researchers, while the MHE prevalence rates in three groups of patients with Child-Pugh classes A, B, and C were 8.29%, 23.53%, and 38.24%, respectively, according to the normal value standards of Korean researchers. Furthermore, the prevalence rates of MHE in the three groups of patients with Child-Pugh grades A, B, and C were 52.68%, 58.82%, and 73.53%, respectively, according to the Stroop test standard. However, among the results of each diagnostic standard, the prevalence of MHE showed an increasing trend with an increasing Child-Pugh grade. Further comparison demonstrated that the scores obtained by the number connection test A and the number symbol test were consistent according to the normal value standards of the two studies in China and South Korea ( Z = -0.982, -1.702; P = 0.326, 0.089), while the other three sub-tests had significant differences ( P < 0.001). Conclusion:The prevalence rate of MHE in the cirrhotic population is high, but the prevalence of MHE obtained by using different diagnostic criteria or methods varies greatly. Therefore, in line with the current changes in demographics and disease spectrum, it is necessary to enroll a larger sample size of a healthy population as a control. Moreover, the establishment of more reliable diagnostic scoring criteria will serve as a basis for obtaining accurate MHE incidence and formulating diagnosis and treatment strategies in cirrhotic populations.

【Objective】 To analyze the current situation of direct exemption of clinical blood fess for voluntary blood donors and their family members in Henan Province, in order to improve and fully implement the policy. 【Methods】 According to the policy on blood fees exemption issued by China and Henan Province in 2019,the data of hospitals in 18 prefecture-level cities in Henan from 2020 to 2021 were continuously collected from the system of clinical blood fees exemption,including the way of exemption,the number of people (times) of exemption,exemption amount, the proportion of blood fees exemption and the total exemption rate. The experience gained in the past two years after the implementation of the policy was summarized,and the existing problems and causes were analyzed. 【Results】 The rates of direct exemption of blood fees in Henan Province in 2020 and 2021 were 34.53% (8 709/25 221) and 71.68%(23 587/32 906) (P<0.05) ,respectively. In 2021, the direct exemption rate of blood fees in 18 cities was 6.20% (83/1 370) to 88.50% (1 332/1 505) [ (47.35±41.15)%],and increased month by month from 43.19% (1 183/2 507) in January to 83.15% (2 097/2 522) in August, then remained stable at a similar level to August from September to December, with 83.43% (2 744/3 289) in December as the highest for the year. 【Conclusion】 The implementation of the policy of blood fees exemption showed significant effectiveness, which has effectively promoted the development of voluntary blood donation in Henan. However, there is still room for improving the policy in some cities, which is expected to further increase the direct exemption rate of the city and the whole province.
