MethodsOne hundred and fourteen patients with heart failure with reduced ejection fraction （HFrEF） and heart failure with mildly reduced ejection fraction （HFmrEF） were randomly allocated into a control group and an observation group. The control group was treated with dapagliflozin tablets， sacubitril-valsartan sodium tablets， metoprolol succinate， and spironolactone， and the observation group was treated with Ershen Zhenwu Decoction on the basis of the therapy in the control group. The course of treatment was 8 weeks in both groups. The 6-min walking distance， New York Heart Association （NYHA） heart function grade， Minnesota Living with Heart Failure Questionnaire （MLHFQ） score， N-terminal pro-B-type natriuretic peptide （NT-proBNP）， angiotensin Ⅱ （Ang Ⅱ）， left ventricular ejection fraction （LVEF）， left ventricular end-diastolic diameter （LVIDd）， left ventricular end-systolic diameter （LVIDs）， interventricular septum thickness at diastole （IVSd）， left ventricular end-diastolic posterior wall thickness （LVPWd）， left ventricular shortening fraction （FS）， miR-423-5p， Smad7， Smad2， Smad3， Smad4， TGF-β₁， Ang Ⅱ， type Ⅰ collagen （Col Ⅰ）， type Ⅲ collagen （Col Ⅲ）， mRNA levels of fibronectin （Fn） and α-smooth muscle actin （α-SMA） in the myocardial tissue were observed before and after treatment in both groups to evaluate the efficacy of cardiac function and drug safety. ResultsAfter treatment， both groups showed declined levels of NT-proBNP， Ang Ⅱ， miR-423-5p， Smad2， Smad3， Smad4， TGF-β₁， Col Ⅰ， Col Ⅲ， and mRNA levels of Fn and α-SMA （P0.05）， and the levels of the indicators above were lower in the observation group than in the control group （P0.05）. After treatment， the Smad7 level increased obviously in both groups （P0.05） and was higher in the observation group than in the control group （P0.05）. After treatment， both groups showed decreased MLHFQ scores and increased 6-min walking distance （P0.05）， and the observation group had lower MLHFQ score and longer 6-min walking distance than the control group （P0.05）. After treatment， the control group showed increased LVEF and FS （P0.05） and the observation group showcased decreased LVIDd and LVIDs and increased LVEF and FS （P0.05）. Moreover， the observation group had lower LVIDd and LVIDs （P0.05） and higher LVEF and FS （P0.05） than the control group. The total response rate of cardiac function in the observation group was 90.38% （47/52）， which was higher than that （70.59%， 36/51） in the control group （P0.05）. No adverse reactions associated with Ershen Zhenwu Decoction were observed during the study period. ConclusionErshen Zhenwu Decoction can improve the cardiac function， exercise tolerance， and quality of life， regulate neuroendocrine factors， and slow down/reverse myocardial remodeling in the patients with HFrEF and HFmrEF （syndrome of heart-kidney Yang deficiency and blood stasis by regulating the miR-423-5p/Smad7/TGF-β₁/Smads axis， inhibiting α-SMA and Fn expression， and alleviating myocardial fibrosis.

Objective:To evaluate the effectiveness of an integrated management model involving the Centers for Disease Control and Prevention (CDC), general hospitals, and community health service centers in improving outcomes for community-dwelling patients with chronic obstructive pulmonary disease (COPD), with the aim of optimizing existing COPD management strategies.Methods:This study was a cluster randomized controlled trial. From January to March 2022, a total of 236 patients with COPD were recruited from four communities in Chibi City, Hubei Province. Ultimately, 223 patients completed follow-up and participated in the intervention evaluation. The participants were cluster-randomized into an intervention group ( n=121) and a control group ( n=102). The intervention group received a one-year "trinity" integrated community management model, while the control group received only basic follow-up. Face-to-face questionnaires were administered before and after the intervention to collect data on demographics, disease awareness, risk factors, respiratory symptoms, medication use, and disease management. Quality of life scores and pulmonary function tests were also assessed. Pre-and post-intervention outcomes were compared using t-tests or chi-square tests. Results:The intervention group demonstrated significantly higher rates of COPD awareness and disease-related knowledge compared to the control group (94.12% vs 77.78% and 78.15% vs 49.49%; both P<0.05), along with lower overall smoking rate and current smoking rate (57.14% vs 70.71% and 29.41% vs 47.47%; both P<0.05). The intervention group showed reduced household polluting fuel use for heating (17.65% vs 28.93%; P<0.05), while the control group exhibited no significant change. Significant improvements were observed in the intervention group for inhaler medication usage (14.05% vs 2.94%), exercise training, and respiratory muscle training (22.31% vs 2.94% and 26.45% vs 0.98%)(all P<0.05). Additionally, the intervention group reported lower prevalence of chronic sputum production, wheezing, and dyspnea (12.40%, 0.83%, 27.27% vs 24.51%, 9.80%, 41.18%; all P<0.05) compared to controls. Pulmonary function tests revealed that the percentage of forced expiratory volume in one second (FEV 1%predicted) was significantly higher in the intervention group than in the control group [(69.53±18.01)% vs (54.90±12.39)%; both P<0.05]. Conclusions:The "trinity" integrated management model effectively enhances health literacy, self-management capabilities, and quality of life among COPD patients, while reducing behavioral risk factors. This model aligns with the long-term and individualized management needs of COPD patients.

Objective:To observe the therapeutic effect of Edaravone Dexborneol combined with aspirin and clopidogrel in the treatment of acute ischemic stroke(AIS).Methods:82 AIS patients were randomly divided into control group(treated with aspirin and clopidogrel,n=41)and observation group(treated with Edaravone Dexborneol on the basis of control group,n=41)by random number table method.National Institutes of Health Stroke Scale(NIHSS),Montreal Cognitive Assessment Scale(MoCA),Barthel Index(BI),serum biochemical indicators[neuron specific enolase(NSE),superoxide dismutase(SOD),brain-derived neurotrophic factor(BDNF),malondialdehyde(MDA)],intracranial hemodynamic indicators[bilateral anterior cerebral artery(ACA),bilateral middle cerebral artery(MCA),bilateral posterior cerebral artery(PCA)],and incidence of adverse reactions during treatment were compared between the two groups.Results:The total clinical effective rate,MoCA,BI score,BDNF,SOD,and the average flow rates of ACA,MCA,and PCA in the observation group 14 d after treatment were higher than those in control group,NIHSS score,NSE,and MDA were lower than those in control group(P＜0.05).There was no significant difference in the incidence of adverse reactions between the two groups(P＞0.05).Conclusion:Edaravone Dexborneol combined with aspirin and clopidogrel in AIS treatment can significantly improve intracranial hemodynamics,regulate nerve factors,reduce nerve function damage,and has good safety.

Objective To investigate the correlation of serum miR-146a-3p and miR-155-5p levels with the progression of allergic rhinitis(AR)patients and the efficacy of Dermatophagoides farinae drops.Methods From February 2023 to April 2024,115 patients with AR who visited our hospital were included as the rhinitis group,and were assigned into mild group(63 cases)and moderate-to-severe group(52 cases)according to the severity of their condition.Another 100 healthy individuals who experienced physical check-ups were selected as the healthy group.Patients with AR were treated with Dermatophagoides farinae drops and assigned into an effective group(87 cases)and an ineffective group(28 cases)based on the efficacy.ELISA method was used to detect serum specific immunoglobulin E(IgE)level;RT-qPCR was used to detect the relative expression levels of serum miR-146a-3p and miR-155-5p.The total nasal symptom score(TNSS)and visual analogue scale(VAS)were used to assess the severity of clinical symptom;Pearson method was used to analyze the correlation of serum miR-146a-3p,miR-155-5p with IgE,VAS and TNSS;ROC was used to analyze the predictive value of serum miR-146a-3p and miR-155-5p for the progression of AR and the efficacy of Dermatophagoides farinae drops.Results The serum miR-146a-3p and miR-155-5p levels in the rhinitis group were higher than those in the healthy group(P＜0.05);the VAS,TNSS,IgE level,miR-146a-3p and miR-155-5p levels in the moderate-to-severe group were higher than those in the mild group(P＜0.05).Serum miR-146a-3p and miR-155-5p were positively correlated with IgE level,VAS and TNSS(P＜0.05).The AUC of serum miR-146a-3p combined miR-155-5p in predicting the progression of AR was higher than that of serum miR-146a-3p or miR-155-5p alone(Zcombination-miR-146a-3p=2.344,P=0.019,Z combination-miR-155-5p=2.335,P=0.020).Before treatment,the serum miR-146a-3p and miR-155-5p levels in the effective group were lower than those in the ineffective group.After treatment,the serum miR-146a-3p and miR-155-5p levels were decreased in the ineffective and effective groups,especially in the effective group(P＜0.05).The AUC of the combination of serum miR-146a-3p and miR-155-5p in predicting the efficacy of Dermatophagoides farinae drops was higher than that of serum miR-146a-3p or miR-155-5p alone(Z combination-miR-146a-3p=2.277,P=0.023,Z combination-miR-155-5p=2.268,P=0.023).Conclusion The levels of serum miR-146a-3p and miR-155-5p in patients with AR are elevated and closely related to the severity of clinical symptoms and IgE level.Combined detection of serum miR-146a-3p and miR-155-5p can predict the progression of AR and the efficacy or treatment response of Dermatophagoides farinae drops.

Objective To investigate the relationship between serum cystatin C(CysC)level and the risk of Parkinson's disease(PD)in middle-aged and elderly people in China.Methods Based on the baseline survey data from the China Health and Retirement Longitudinal Study(CHARLS)in 2011,participants who were not diagnosed with PD at the time of the baseline survey were recruited.The onset of PD was tracked and followed up until 2020,and the participants were divided into PD group and non-PD group according to whether they were newly diagnosed with PD in 2020.Multivariable Logistic regression analysis was performed to assess the association between serum CysC level and the risk of PD.Subgroup and interaction analyses were performed to assess effect modifications by age,gender and depression.Additionally,restricted cubic spline(RCS)was used to explore the linear or non-linear relationship between serum CysC level and the risk of PD in different subgroups.Results We included a total of 3 339 subjects in this study,who consisted of 1 495 males(44.77％)and 1 844 females(55.23％).While baseline participants were followed until 2020,32 subjects had a new PD,and the incidence of PD was 0.96％.The median age of PD group was 63.00 years.Multivariable Logistic regression analysis found that CysC was an independent risk factor for the risk of PD,and CysC was positive significantly associated with the risk of PD(OR=2.34,95％ CI:1.14-4.82,P=0.021).Subgroup analysis showed that CysC was positively associated with PD in females(OR=2.70,95％ CI:1.30-5.58,P=0.007)and subjects aged 60 years or older(OR=5.29,95％ CI:1.69-16.53,P=0.004).RCS model indicated a linear relationship between serum CysC level and the risk of PD in females(Ptotal=0.018,Pnon-linear=0.062)and subjects aged 60 years or older(Ptotal=0.024,Pnon-linear=0.379).Conclusion High level of CysC may increase the risk of PD in middle-aged and elderly people,especially in females and those aged 60 years or older.

Aim To explore the mechanism by which the compound Chaijin Jieyu formula(CCJJY)regulates the TLR4/NLRP3 signaling pathway to inhibit central oxidative stress and improve hippocampal synaptic plasticity damage in depression.Methods SD rats were randomly divided into the control group,chronic unpredictable mild stress group,sleep deprivation group,chronic unpredictable mild stress combined with sleep deprivation group,positive drug group(venlafax-ine+melatonin),low-dose group of CCJJY,medium dose group of CCJJY,and high-dose group of CCJJY,with nine rats in each group.Except for the control group,a rat model of depression complicated with in-somnia was established using chronic unpredictable mild stress combined with sleep deprivation.Depres-sion-like and sleep behaviors in rats were evaluated through weight,food intake,water maze,and pento-barbital sodium tests.ELisa was used to detect ROS,AANAT,and HPLC-EC was used to detect 5-HT con-tent,while Western blot/RT-PCR was used to detect the expression of IL-1β,TLR4,NLRP3,PSD-95,and SYN related proteins and mRNA.HE and Golgic stai-ning were used to observe the pathological changes in the third ventricle,hippocampus,and neuronal synap-ses.Results Compared with the control group,the depression-like behaviors of the model group rats were significant.The expression of IL-1β,TLR4,and NL-RP3 in the hippocampus increased,while the expres-sion of PSD-95 and SYN decreased.Activation of NL-RP3 inflammasomes led to "sleeve like" pathological changes in the third ventricle,with hippocampal neu-rons undergoing apoptosis and significant damage to neuronal synaptic plasticity.Compared with the model group,after intervention with CCJJY,the expression of ROS,IL-1β,TLR4,and NLRP3 decreased,while the expression of AANAT,5-HT,PSD-95,and SYN in-creased.Pathological damage to the third ventricle and hippocampal neurons was repaired.Conclusion The CCJJY improves hippocampal synaptic plasticity dam-age in depression by regulating the TLR4/NLRP3 sig-naling pathway to inhibit central oxidative stress.

Objective To analyze the burden of pressure ulcers and its changing trends among the general population(all age groups)and the elderly aged 65 years and above in China based on the global burden of disease(GBD)data from 1990 to 2021,predict the burden trends from 2022 to 2035,and address the public health issues of its unclear medium-and long-term trends and insufficient precise interventions in its prevention and control in order to provide support for formulating targeted prevention and control strategies.Methods The GBD database was used to extract the incidence,mortality and disability-adjusted life years(DALYs)of pressure ulcers in the general population and in the elderly aged 65 years and above in China from 1990 to 2021.Meanwhile,the age-standardized incidence rate(ASIR),mortality rate(ASMR),and disability-adjusted life rate(ASDR)of the general population were also extracted,and the age-standardized rate(ASRs)corresponding to the elderly population aged 65 years and above were estimated based on the GBD 2021 standard population.The average annual percentage changes(EAPCs)of ASRs were calculated to assess the trends.Bayesian age-period-cohort(BAPC)model was adopted to predict the ASRs and their changing trends of the general and elderly population from 2022 to 2035,respectively.Results From 1990 to 2021,the number of pressure ulcer cases in the general population of China increased from 163 508.67(95%CI:142 891.48～184 055.10)cases to 397 312.27(95%CI:360 058.44～444 875.78)cases,the number of deaths soared from 242.51(95%CI:125.26～702.84)cases to 3 131.54(95%CI:1 562.60～4 126.85)cases,and DALYs increased from 11 965.10(95%CI:7 820.54～21 703.78)to 61 933.91(95%CI:36 313.26～77 402.42).During the same period,the EAPCs of ASIR,ASMR and ASDR were 1.06(95%CI:0.84～1.28),3.63(95%CI:3.45～3.81),and 2.76(95%CI:2.60～2.92),respectively.In 2021,the number of male cases and DALYs were both higher than those of females,while the number of deaths was similar.The ASIR,ASMR and ASDR of the males were all higher than those of the females,and the growth rates of both genders were relatively fast.All indicators were increased significantly with age.It is predicted that by 2035,the ASIR,ASMR,and ASDR in the general Chinese population will continue to rise significantly.From 1990 to 2021,the number of pressure ulcer cases among the elderly(≥65 years old)in China increased from 42 334.95(95%CI:35 739.05～48 930.84)to 238 431.65(95%CI:212 539.53～264 323.77).The number of deaths rose from 204.97(95%CI:93.33～316.60)to 2 871.02(95%CI:2 334.39～3 407.66),and DALYs increased from 4 619.74(95%CI:2 990.73～6 248.76)to 43 968.28(95%CI:37 542.85～50 393.70).The EAPCs of ASIR,ASMR,and ASDR were 2.62(95%CI:2.44～2.80),3.54(95%CI:3.38～3.70),and 3.28(95%CI:3.14～3.42),all of which increased significantly.In 2021,the number of cases,deaths and DALYs among elderly men and women were similar,but the ASIR,ASMR and ASDR of men were all higher than those of women,and their growth rates were faster.It is projected that by 2035,the ASIR of the elderly population will significantly decline to 146.24(95%CI:140.35～152.14),with an EAPC of-0.57(95%CI:-0.64～-0.50),while the ASMR and ASDR will continue to rise and remain higher in males than in females.Conclusion From 1990 to 2021,the number of pressure ulcer cases,deaths and DALYs among the general population and the elderly in China increased significantly,and the ASRs rose rapidly.The burden of pressure ulcers increases significantly with age and is higher in men than in women.Predictions show that ASIR in the general population will continue to rise,while that in the elderly will slightly decline.However,the ASMR and ASDR will continue to increase.Countermeasures Continuously strengthen the prevention and control of pressure ulcers,implement precise intervention for the elderly,especially older men,promote standardized nursing guidelines,enhance training and resource input in primary medical care,and establish a national pressure ulcer monitoring system.
