Objective To analyze the prevalence of hyperuricemia (HUA) among adults in Hebei Province and its influencing factors related to comorbidities with ^“three highs^”, and to provide a theoretical basis for the prevention and control of HUA and multi-disease co-management. Methods Data were derived from the 2018 China Chronic Disease and Risk Factors Surveillance program conducted in Hebei Province. A multi-stage stratified cluster random sampling method was used to select permanent residents aged ≥18 years. All statistical analyses were adjusted for complex weighting. Design-based logistic regression was employed to analyze factors influencing HUA prevalence, and ordinal logistic regression was used to analyze the influencing factors of HUA patients and their comorbidity with ^“three highs^”. Results The prevalence of HUA among adults in Hebei Province was 10.42%, with males showing higher rates than females (P<0.05). The highest prevalence of HUA was observed in the 18-39 age group, followed by a declining trend, and a resurgence in those aged ≥70 (P<0.05). Among HUA patients with comorbidities, isolated HUA, 1 comorbidity, 2 comorbidities, and 3 comorbidities accounted for 13.94%, 33.33%, 39.17%, and 13.56%, respectively. HUA combined with hypertension and dyslipidemia represented the highest proportion (31.07%). Analysis of the influencing factors of HUA revealed that higher education levels, obesity, central obesity, and dyslipidemia increased the risk of HUA (P<0.05). Ordinal logistic regression analysis of HUA combined with three highs showed that HUA patients aged ≥50 years, overweight individuals, and those with chronic kidney disease had a higher number of patients with three highs (P<0.05). Conclusion HUA exhibits insidious onset, and it is recommended to include uric acid testing in routine physical examinations. Targeted prevention measures, such as early uric acid testing and health education, should be implemented by Hebei authorities for populations with higher education levels, obesity, central obesity, and dyslipidemia to reduce HUA incidence. Additionally, health education and regular medical check-ups are recommended for overweight HUA patients and those with chronic kidney disease to prevent comorbidities and alleviate disease burden.

Objective To investigate the relationship between the comorbidity of dyslipidemia, hypertension and diabetes and lifestyle of adult residents in Hebei Province in 2018, and to provide reference for the development of chronic diseases prevention measures. Methods Using data from the surveillance of chronic diseases and their risk factors among adults in Hebei in 2018, 7 711 permanent residents aged ≥18 years were selected as the research subjects. Multivariate logistic regression analysis was used to analyze the relationship between the comorbidity of dyslipidemia, hypertension, and diabetes and lifestyle in adult residents. Results A total of 7 711 subjects aged ≥18 years were included in 2018. The comorbidity rates of hypertension and dyslipidemia, diabetes and dyslipidemia, and hypertension and diabetes were 16.88%, 7.91%, and 8.13%, respectively. The comorbidity rate of hypertension, diabetes, and dyslipidemia was 22.65%. These comorbidity rates increased with age and BMI. Multivariate logistic regression results showed that male, age, overweight/obesity, physical inactivity, daily sedentary behavior time ≥5 hours, and sleep problems were risk factors for the comorbidity of the "three highs". Conclusion The prevalence of the "three highs" comorbidities is relatively high in Hebei Province, and there are multiple common risk factors. Maintaining a healthy lifestyle and implementing comprehensive prevention and control measures are the key to improving the health level of residents.

OBJECTIVE To explore the pharmacokinetic characteristics of 3 blood-absorbed components of Xiangshao sanjie oral liquid in rats with hyperplasia of mammary gland （HMG）. METHODS Female SD rats were divided into control group and HMG group according to body weight， with 6 rats in each group. The HMG group was given estrogen+progesterone to construct HMG model. After modeling， two groups were given 1.485 g/kg of Xiangshao sanjie oral liquid （calculated by crude drug） intragastrically， once a day， for 7 consecutive days. Blood samples were collected before the first administration （0 h）， and at 5， 15， 30 minutes and 1， 2， 4， 8， 12， 24 hours after the last administration， respectively. Using chlorzoxazone as the internal standard， the plasma concentrations of ferulic acid， paeoniflorin and rosmarinic acid in rats were detected by UPLC-Q/TOF-MS. The pharmacokinetic parameters [area under the drug time curve （AUC0－24 h， AUC0－∞）， mean residence time （MRT0－∞）， half-life （t1/2）， peak time （tmax）， peak concentration （cmax）] were calculated by the non-atrioventricular model using Phoenix WinNonlin 8.1 software. RESULTS Compared with the control group， the AUC0－24 h， AUC0－∞ and cmax of ferulic acid in the HMG group were significantly increased （P＜0.05）； the AUC0－24 h， AUC0－∞ ， MRT0－∞ ， t1/2 and cmax of paeoniflorin increased， but there was no significant difference between 2 groups （P＞0.05）； the AUC0－24 h and MRT0-∞ of rosmarinic acid were significantly increased or prolonged （P＜0.05）. C ONCLUSIONS In HMG model rats， the exposure of ferulic acid， paeoniflorin and rosmarinic acid in Xiangshao sanjie oral liquid all increase， and the retention time of rosmarinic acid is significantly prolonged.

Objective:To investigate the diagnostic value and imaging features of high resolution magnetic resonance imaging(HR-MRI)in patients with lesions in carotid artery and intracranial artery.Methods:Sixty-nine patients with suspected lesions in carotid artery and intracranial artery who admitted to Handan Central Hospital from June 2021 to December 2023 were selected,and they underwent routine MRI and HR-MRI examinations.Digital subtraction angiography(DSA)examination was used as the"gold standard"to analyze the detection rates of different MRI examinations for lesions in carotid artery and intracranial artery.The diagnostic efficacy of them was calculated,and the HR-MRI imaging features of positive cases and negative patients were compared under the"gold standard".Results:For 69 patients with suspected lesions in carotid artery and intracranial artery,41 cases(59.42%)were confirmed by"gold standard"examination,and 31 positive cases were confirmed by routine MRI examination,and 35 positive cases were confirmed by HR-MRI examination,and 39 positive cases were confirmed by combined examination of routine MRI and HR-MRI.The results indicated that the accuracy,sensitivity,specificity,positive and negative predictive values of the combined examination of routine MRI and HR-MRI were respectively 88.41%,87.80%,89.29%,92.31%and 83.33%,all of which were higher than those of single image examination,and the differences were statistically significant(x2=5.459,7.329,6.216,6.395,6.141,P<0.05).The irregular shape,blurred boundary,high signal,plaque formation,intra-plaque bleeding,displacement of common carotid artery or vein,and calcification of lesion in HR-MRI imaging features of positive patients were significantly higher than those of negative patients,and the differences were statistically significant(x2=8.918,4.418,7.001,4.746,8.743,5.951,4.947,P<0.05),respectively.Conclusion:The detection rates both of routine MRI and HR-MRI are higher in patients with lesions in carotid artery and intracranial artery.However,the combined examination of them can improve the diagnostic sensitivity and specificity,and the morphology,boundary,signal and calcification foci of confirmed patients are more obvious in HR-MRI examination,which can provide reference for subsequent diagnosis and treatment.

Objective:To investigate the feasibility of the bortezomib, lenalidomide, and dexamethasone (VRD) regimen combined with autologous hematopoietic stem cell transplantation (auto-HSCT) in patients with multiple myeloma (MM) and renal impairment, analyze treatment efficacy and renal responses stratified based on renal dysfunction severity, and explore the prognostic significance of early renal response and its affecting factors.Methods:This retrospective study, conducted at the First Affiliated Hospital of Soochow University, categorized 316 patients with newly diagnosed MM (NDMM) from August 2018 to October 2022 based on renal function for analysis of clinical characteristics, treatment response, and prognosis. Continuous variables were compared using t-tests or Mann-Whitney U tests, categorical variables utilizing Chi-square tests, survival outcomes employing Kaplan-Meier and Log-rank tests, and renal response predictors with logistic regression.Results:Patients were stratified based on baseline estimated glomerular filtration rate (eGFR) : normal [≥90 ml·min -1· (1.73 m 2) -1, n=160], mild [≥60 ml·min -1· (1.73 m 2) -1 to <90 ml·min -1· (1.73 m 2) -1, n=55], moderate [≥30 ml·min -1· (1.73 m 2) -1 to <60 ml·min -1· (1.73 m 2) -1, n=39], and severe impairment [<30 ml·min -1· (1.73 m 2) -1, n=62]. Moderate and severe renal impairment correlated with advanced International Staging System/Revised International Staging System classification, lower hemoglobin levels, frailty, and higher light-chain/IgD subtype prevalence ( P<0.05). Despite younger age ( P=0.001) and higher transplant rates ( P=0.041) in severe cases, overall response rates ( ORR: 93.7% ; ≥VGPR: 82.9% ) were comparable across groups ( P>0.05). Among 24 dialysis-dependent patients at diagnosis, 11 (45.8% ) achieved dialysis independence after induction [median: 3.0 (0.5–4.0) months], including 10 undergoing auto-HSCT. In 89 evaluable patients [baseline eGFR <50 ml·min -1· (1.73 m 2) -1], renal ORR (RORR) was 70.8% [rapid complete response: 31.5% ; rapid partial response: 11.2% ; rapid minimal response (RMR) : 28.1% ]. Renal response predicted better survival (overall survival: HR=0.36, 95% CI: 0.13–0.99, P=0.049). Moderate-to-severe renal impairment was associated with increased transplant-related adverse events and delayed engraftment ( P<0.05) ; however, auto-HSCT significantly improved outcomes after 33.5-month median follow-up (range: 2–65 months). Multivariate analysis identified 1q21+ ( OR=3.58, 95% CI: 1.17–11.02, P=0.026) and light-chain subtype ( OR=2.86, 95% CI: 1.08–7.69, P=0.036) as independent predictors of poor renal response. Conclusion:VRD regimen plus auto-HSCT demonstrates robust efficacy in NDMM, including patients with renal impairment, with a 70.8% RORR and manageable toxicity. Achieving ≥RMR correlates with superior prognosis, whereas 1q21+ and light-chain subtype independently predict inferior renal response.

Objective:To explore the application value of multi-slice spiral CT (MSCT) perfusion imaging and magnetic resonance high-resolution vessel wall imaging (HR-VWI) in the evaluation of atherosclerotic ischemic stroke (IS).Methods:A total of 131 patients with atherosclerotic IS (study group) and 62 patients with non-atherosclerotic IS (control group) diagnosed and treated in Handan Central Hospital from May 2022 to May 2024 were retrospectively selected as the study objects. MSCT perfusion imaging and HR-VWI were completed before treatment. MSCT perfusion imaging indexes and HR-VWI indexes were compared between the two groups, and HR-VWI indexes and MSCT perfusion imaging indexes were compared among the study groups with different disease degrees. Receiver operating characteristics (ROC) curve was used to analyze the diagnostic value of HR-VWI indexes and MSCT perfusion imaging indexes in atherosclerotic IS.Results:The stenosis degree, out wall area at maximal lumen narrowing (OWA MLN), plaque loading rate and remodeling index in the study group were higher than those in the control group: (69.22 ± 12.57)% vs. (60.81 ± 10.38)%, (7.62 ± 1.03) mm 2 vs. (6.53 ± 1.18) mm 2, (42.51 ± 8.22)% vs. (36.53 ± 7.29)%, 1.32 ± 0.41 vs. 1.01 ± 0.29; while the lumen area at maximal lumen narrowing (LA MLN) in the study group was lower than that in the control group: (0.84 ± 0.28) mm 2 vs.(1.17 ± 0.41) mm 2, there were statistical differences ( P<0.05). The cerebral blood flow (CBF) and cerebral blood volume (CBV) in the study group were lower than those in the control group: 20.25 ± 2.83) ml/100 min vs. (23.66 ± 2.52) ml/100 min, (1.82 ± 0.53) ml/100g vs. (2.31 ± 0.63) ml/100 g; and the peak time (TTP) and mean transit time (MTT) in the study group were higher than those in the control group: (23.55 ± 4.86) s vs.(19.73 ± 3.73) s, (7.13 ± 1.22) s vs. (6.17 ± 1.06) s, there were statistical differences ( P<0.05). In the study group, with the aggravation of disease severity, the stenosis degree, OWA MLN, plaque load rate and remodeling index were gradually increased, while LA MLN was gradually decreased, there were statistical differences ( P<0.05). ROC curve analysis results showed that the area under the curve value of HR-VWI index combined evaluation and MSCT perfusion imaging index combined evaluation in the diagnosis of atherosclerotic IS was 0.921 and 0.828, respectively. Conclusions:HR-VWI and MSCT perfusion imaging can be used in the assessment of patient's condition of atherosclerotic IS. HR-VWI may be better in evaluating the condition of atherosclerotic IS.

Objective:To analyze the prevalence of chronic kidney disease (CKD) and influencing factors of adults in Hebei Province, and provide scientific evidence for the development of comprehensive CKD prevention and control strategies.Methods:In China Adult Chronic Disease and Nutrition Surveillance in Hebei in 2018, a total of 7 562 permanent residents aged ≥18 years were selected by multi-stage stratified cluster random sampling from 13 surveillance points in Hebei for questionnaire survey, medical examination and laboratory test.Results:A total of 1 067 CKD patients were detected in the adults aged ≥18 years in this survey, with a weighted prevalence rate of 12.10%. The results of multivariate analysis showed that the daily total static behavior time ( OR=1.07, 95% CI: 1.04-1.09), living in rural area ( OR=1.50, 95% CI: 1.14-1.97), coal use ( OR=1.37, 95% CI: 1.16-1.61), coal gas/liquefied gas/natural gas/biogas use ( OR=2.92, 95% CI: 2.40-3.54) and solar energy/electricity use ( OR=1.75, 95% CI: 1.36-2.25), insufficient fruit intake ( OR=1.39, 95% CI: 1.06-1.83), insufficient physical activity ( OR=1.35, 95% CI: 1.11-1.64), suffering from hypertension ( OR=1.80, 95% CI: 1.44-2.24) and suffering from diabetes ( OR=1.77, 95% CI: 1.27-2.45) were risk factors for CKD in adults in Hebei. High education level ( OR=0.41, 95% CI: 0.19-0.91), excessive drinking ( OR=0.53, 95% CI: 0.28-0.99), central obesity ( OR=0.75, 95% CI: 0.58-0.97), history of allergic diseases ( OR=0.44, 95% CI: 0.27-0.72) were protective factors for CKD. Conclusions:The prevalence of CKD in adults in Hebei was relatively high, especially in those who had too long average daily static behavior, lived in rural area, used coal, gas/liquefied gas/natural gas/biogas, solar energy/electricity, had inadequate intake of fruits, lacked physical activity and suffered from hypertension and diabetes. It is necessary to pay attention to the early prevention and treatment of CKD, strengthen the health education about healthy lifestyle and improve the management of patients with chronic disease, such as hypertension and diabetes, to further reduce the risk for CKD.

Autoimmune disease is a kind of disease characterized by immune imbalance,abnormal activation of immune cells,massive production of inflammatory factors and immune complexes,which leads to the damage of multiple organs and systems.Autoimmune disease is easy to recur in clinical practice.The previous studies showed that there is a correlation between dampness syndrome in traditional Chinese medicine(TCM)and immune dysfunction.This paper explains the theoretical basis for the correlation between dampness syndrome of TCM and the recurrence of autoimmune diseases,and the similarities between the two in macro appearance,pathogenesis characteristics,etc.,analyzes the possible correlation about biological mechanism between dampness syndrome and autoimmune diseases,and discussed the correlation between pathogenic dampness of TCM and the recurrence of autoimmune diseases such as psoriasis,rheumatoid arthritis,ulcerative colitis,and nephrotic syndrome.It is pointed out that pathogenic dampness of TCM is an important pathogenic factor for the recurrence of autoimmune diseases,and is closely related to the recurrence of autoimmune diseases.Autoimmune diseases can be treated from the perspective of pathogenic dampness in TCM,and therapy of invigorating spleen,replenishing qi and removing dampness is frequently adopted,which is beneficial to alleviating the clinical symptoms of patients and reducing the recurrence of autoimmune disease.

Objective To identify S-palmitoylation sites on angiotensin-converting enzyme 2(ACE2),the cellular receptor for severe acute respiratory syndrome corona virus(SARS-CoV)and SARS-CoV-2,and to investigate the functional relevance of these modifications in regulating ACE2 localization and activity.Methods An optimized multi-site mutagenesis strategy was performed by simultaneously substitution of all eight cysteine(Cys)residuesin ACE2 by serine to create a non-palmitoylatable mutant(8CS).Then individual cysteine residues were re-introduced one by one.Palmitoylation level of mutants was evaluated using a bioorthogonal click chemistry method to identify palmitoylation-competent residues.Immune-fluorescence staining and extra-cellular vesicle isolation assays were then used to evaluate the impact of specific palmitoylation sites on ACE2 sub-cellular localization.Results An efficient strategy for multi-site palmitoylation site mapping was optimized and successfully identified three critical palmitoylation sites on ACE2:Cys141,Cys344 and Cys498.Functional analyses showed that palmi-toylation of these sites significantly promotes the enrichment of ACE2 in extra-cellular vesicles.Conclusions S-palmitoylation at Cys141,Cys344 and Cys498 is essential for the trafficking of ACE2 to extra-cellular vesicles,which suggests a potential regulatory mechanism of its impact on viral receptor presentation and ACE2-associated signaling pathways.

The incidence of apoplexy remains persistently high among the older population.Based on the traditional Chinese medicine principle of"treating the elderly by focusing on the fu",this paper explores the holistic connotation of"fu".It proposes that the onset of apoplexy in the elderly is characterized by obstruction,stagnation,depression,and sluggishness,which should be treated from six fu viscera,xuanfu,and collaterals.The interconnected hierarchical network of these three systems,serving as macro-and micro-channels for qi and fluid metabolism,plays a central role in both disease development and treatment.The failure of the six fu viscera to descend and the upward invasion of turbid yin are identified as prerequisites for apoplexy onset,whereas yang qi stagnation and xuanfu blockage act as key pathogenic drivers,and the core mechanisms involve phlegm-stasis-toxin accumulation,and dysfunction of the collaterals and fu.In the treatment,acute phase requires unblocking fu viscera and restoring xuanfu patency;chronic phase focuses on dredging collaterals and opening xuanfu;and recovery phase emphasizes tonifying combined with regulating xuanfu.The understanding of"treating the elderly by focusing on the fu"emphasizes that the pathogenesis of the disease should be changed to individual conditions;"six fu viscera-xuanfu-collaterals"exhibits a pathological mechanism characterized by the transmission and reception of pathogenic factors,as well as progressive mutual involvement;in clinical practice,treatment should meticulously assess the severity and nuances of the condition,prioritizing method that emphasizes unobstructed flow;additionally,therapy should be essential to protect stomach qi and integrate therapeutic attacks within a framework of supplementation.These principles offer valuable reference for the differentiation and treatment of apoplexy.
