Objective To investigate the influencing factors of stroke patients with hypertension and their compliance with antihypertensive drugs, and to provide targeted intervention measures for stroke prevention in hypertensive patients.  Methods Using the method of multi-stage cluster sampling, a total of 59,434 permanent residents aged 40 and above were selected from 48 monitoring sites in 9 cities of Hebei Province from December 2019 to December 2020. Unconditional logistic regression analysis was used to explore the influencing factors of stroke complicated with hypertension and the compliance of patients with antihypertensive drugs.  Results Among the 59 434 subjects, the prevalence rate of stroke was 4.33% and the prevalence rate of stroke complicated with hypertension was 82.47%. The results of univariate analysis showed that the proportion of women, rural areas, dyslipidemia, diabetes, obesity, and people with family history of stroke was higher in stroke patients with hypertension, and the difference was statistically significant (P<0.05). Multivariate logistic regression analysis showed that rural areas, dyslipidemia, diabetes, obesity, and family history of stroke significantly increased the risk of stroke, and the OR (95%CI) values were 1.29 (1.03-1.62), 1.39 (1.12-1.72), 1.58 (1.25-1.99), 1.61 (1.22-2.12) and 1.60 (1.26-2.04), respectively. Among stroke patients with hypertension, 92.71% of patients took antihypertensive drugs. It was found that women's compliance with antihypertensive drugs was good, with an OR (95%CI) value of 1.46 (1.01-2.09).  Conclusion The prevalence rate of stroke complicated with hypertension is high in people aged 40 and above in Hebei Province. Hypertensive people should lower blood lipids, control blood glucose, and lose weight as soon as possible to prevent the occurrence of stroke.

ObjectiveTo investigate whether intestinal deficiency of lanosterol synthase （LSS）， a key enzyme in cholesterol synthesis， influences the progression of metabolic dysfunction-associated steatotic liver disease （MASLD） by regulating intestinal cholesterol absorption and immune response. MethodsLSS heterozygous knockout （LSS^+/-） mice and wild-type （WT） controls were generated using CRISPR/Cas9 technology and fed either a high-fat diet （HFD） or regular chow （CHOW）. The model was validated by genotyping. Hepatic steatosis was assessed by HE and oil red O staining. Immunohistochemistry was used to detect the localization and expression of NPC1L1 and CD36 proteins in the intestine. Western blot analysis was performed to measure JNK phosphorylation and TLR4 protein levels in intestinal tissues. Real-time quantitative polymerase chain reaction （qPCR） was employed to examine the mRNA expression of TLR4 and IL-6. ResultsLSS^+/- mice were successfully validated by genotyping and reduced intestinal LSS protein expression. HE and oil red O staining of liver sections showed that， compared with WT mice fed a CHOW diet， WT mice fed a HFD exhibited a marked increase in hepatic lipid vacuoles. In contrast， compared with HFD-fed WT mice， HFD-fed LSS^+/- mice displayed significantly attenuated hepatic lipid deposition and reduced serum ALT levels （P<0.05）. Immunohistochemical analysis revealed that， compared with WT mice， the expression of the cholesterol absorption protein NPC1L1 in the intestinal villi of LSS^+/- mice was downregulated under both CHOW and HFD conditions （P_HFD<0.001）. Conversely， the expression of the fatty acid transporter CD36 was upregulated in the intestines of LSS^+/- mice （P_CHOW<0.05， P_HFD<0.01）. Western blot analysis demonstrated that， compared with WT mice， TLR4 protein expression in the intestines of LSS^+/- mice significantly increased under both CHOW and HFD conditions （both P<0.05）. JNK phosphorylation level was significantly elevated in LSS^+/- mice under CHOW condition （both P<0.05）. Under HFD condition， total JNK protein expression increased， but its phosphorylation level showed no significant change. qPCR analysis showed that， compared with WT mice， the mRNA levels of TLR4 （P_CHOW<0.01， P_HFD<0.000 1） and IL-6 （P_CHOW<0.001， P_HFD<0.01） were significantly upregulated in the intestines of LSS^+/-mice. ConclusionLSS deficiency counteracts hepatic lipid deposition by orchestrating a synergistic reprogramming involving restricted intestinal cholesterol absorption， enhanced fatty acid utilization， and activation of immune pathways， suggesting intestinal LSS as a potential therapeutic target of MASLD.

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.

ObjectiveTo investigate the effect of hypoxia on pemetrexed （PE）-mediated apoptosis in non-small cell lung cancer cells. MethodsA549 cells were cultured under 21% O₂ （normoxia） or 1% O₂ （hypoxia）， and treated with 8 μmol/L PE for 48 h. The cells were divided into normoxic control group， normoxic vehicle group， normoxic drug-treated group， hypoxic control group， hypoxic vehicle group and hypoxic drug-treated group. Trypan blue staining was used to observe cell death after PE intervention under normoxia and hypoxia. Flow cytometry was adopted to detect cell apoptosis rate. Wound healing assay was used to assess cell migration. Western blot was performed to detect the protein levels of MRP-1， Cleaved Caspase-3， E-Cadherin and N-Cadherin. ResultsTrypan blue staining results showed that the cell death rate was reduced in PE-treated cells under hypoxia compared with the normoxic PE group （P<0.001）. Flow cytometry results indicated that PE induced cell apoptosis under both normoxic and hypoxic conditions.However， the apoptosis rate of the normoxic PE group was significantly higher than that of the hypoxic PE group （P<0.000 1）. Wound healing assay showed that the migration distance of A549 cells decreased after PE treatment for 24 h and 48 h under normoxia and hypoxia when compared with the control group （P<0.05）， while no significant difference was found between the normoxic PE group and the hypoxic PE group. Western blot results revealed that MRP-1 expression was markedly higher in hypoxic PE-treated cells than in normoxic PE-treated cells （P<0.000 1）. Compared with the control group， Cleaved Caspase-3 expression was upregulated in A549 cells following PE intervention under normoxia （P<0.05）， whereas no obvious alteration in Cleaved Caspase-3 expression was detected in hypoxic PE-treated cells. Under both normoxic and hypoxic conditions， PE treatment downregulated the expression of E-Cadherin （P<0.000 1，P<0.001） and N-Cadherin （P<0.05，P<0.000 1）. In addition， the expression levels of E-Cadherin and N-Cadherin in the hypoxic PE group were significantly lower than those in the normoxic PE group （all P<0.000 1）. ConclusionHypoxia significantly attenuates the pro-apoptotic effect of PE on A549 cells and blocks Cleaved Caspase-3 activation. This mechanism may be related to hypoxia-induced MRP-1 overexpression and reduced drug accumulation. Interfering with MRP-1 or restoring the activity of the apoptosis pathway may serve as a novel strategy to overcome hypoxia-induced drug resistance.

BackgroundAs a high prevalence disorder， schizophrenia has caused significant burden to family and society due to the impairment of occupational and social function. Currently， the dominant vocational training model in China follows a paternalistic， clinician-led decision-making approach. Although it improves patients' social function to some extent， it undermines their autonomy and treatment adherence. Therefore， it is urgently necessary to explore a new intervention method to enhance treatment compliance and social function in patients. ObjectiveTo explore the impact of shared decision-making oriented vocational training on social function in hospitalized schizophrenia patients， so as to provide references for rehabilitation interventions. MethodsA total of 68 patients diagnosed with schizophrenia according to the International Classification of Diseases， tenth edition （ICD-10） criteria were consecutively enrolled from January to June 2024 at The Third People's Hospital of Wenjiang Distric， Chengdu. Participants were randomly allocated into the research group （n=34） and the control group （n=34） using a random number table method. Both groups received routine rehabilitation training， while the research group received shared decision-making oriented vocational training for 12 weeks， 2 times a week for 2 hours each time. Before and at the 4^th and 12^th week of intervention， two groups were evaluated by General Self-Efficacy Scale （GSES）， Stigma Scale for Mental Illness （SSMI）， Scale of Social function of Psychosis Inpatients （SSFPI） and Inpatient Psychiatric Rehabilitation Outcome Scale （IPROS）. ResultsA total of 63 participants completed the study， with 30 cases in the research group and 33 cases in the control group. Repeated measures ANOVA revealed statistically significant time effects and interaction effects in both groups for GSES， SSMI， SSFPI and IPROS scores （F=20.451， 16.022； 26.193， 12.944； 23.957， 5.023； 11.776， 3.985， P<0.05 or 0.01）， while no significant group effects were observed （F=0.188， 0.742， 1.878， 0.474， P>0.05）. At the 12^th week of intervention， there were statistically significant differences in GSES， SSMI， SSFPI and IPROS scores between the two groups. ConclusionShared decision-making oriented vocational training may help to improve social function in patients with schizophrenia. ［Funded by 2023 Chengdu Medical Research Project （number， 2023468）］

Objective: To investigate the trends in disease burden due to childhood asthma in China from 1990 to 2021 and to project the disease burden from 2022 to 2035, so as to provide insights into formulation of the control interventions for childhood asthma in China. Methods: The prevalent case, agestandard prevalence, disability-adjusted life years (DALYs) and agestandard DALYs rate of children with asthma at ages of 0 to 14 years and their 95% uncertainty interval (UI) in China from 1990 to 2021 were extracted from the Global Burden of Disease (GBD) database. The temporal trends in the disease burden of childhood asthma were evaluated with estimated annual percentage change (EAPC) and its 95% confidence interval (CI), and the disease burden due to asthma was projected among children at ages of 0 to 14 years in China using a Bayesian age-period-cohort (BAPC) model from 2022 to 2035. Results: There were 9.368 3 million (95%UI=6.410 7 million to 14.026 1 million) prevalent cases of asthma among children at ages of 0 to 14 years in China in 2021, contributing to 0.387 9 million (95%UI=0.216 1 million to 0.668 8 million) DALYs loss. The prevalent cases and DALYs of asthma decreased by 37.28% and 52.55% among children at ages of 0 to 14 years in China in 2021 compared with 1990, and the agestandardized prevalence [EAPC=-0.70%, 95%CI=-1.26% to -0.13%)] and DALY rates [EAPC=-1.71%, 95%CI=-2.32% to -1.10%)] also appeared a tendency towards a decline. From 1990 to 2021, the prevalent cases, prevalence, DALYs and DALYs rate of asthma were all higher among male children than among female children, and the disease burden of asthma was higher among children at ages of 5 to 9 years than at other age groups. BAPC model predicted a decline in both prevalent cases and DALYs of asthma among children at ages of 0 to 14 years in China from 2022 to 2035, with 6.759 6 million prevalent cases and DALYs of 0.228 4 million personyears in 2035, while the prevalence and DALYs rates were projected to rise to 5 143.35/105 and 173.75/105 in 2035. Conclusions Despite a reduction in the disease burden of asthma among children at ages of 0 to 14 years in China from 1990 to 2021, the prevalence remained high. The disease burden due to asthma is projected to appear a decline among children at ages of 0 to 14 years in China from 2022 to 2035; however, the prevalence and DALYs rates still rise. Intensified control measures and targeted interventions are required to reduce the disease burden of childhood asthma.

ObjectiveTo explore the possible mechanisms of Wenyang Huazhuo Formula （温阳化浊方， WHF） in improving reproductive aging from the perspective of the ovarian mechanical microenvironment. MethodsThe experiment included five groups， 3-month group （20 female mice at 3 months of age）， 6-month group （20 female mice at 6 months of age）， 6-month + WHF group （20 female mice at 5 months of age treated with WHF）， 9-month group （20 female mice at 9 months of age）， and 9-month + WHF group （20 female mice at 8 months of age treated with WHF）. The 6-month + WHF group and 9-month + WHF group were orally administered WHF 41.2 g/（kg·d） once daily for 4 consecutive weeks. The other three groups received no intervention. Reproductive hormone levels were measured by ELISA. HE staining was used to count the numbers of various stages of follicles. Ovarian hyaluronic acid （HA） content and collagen fiber content were measured to evaluate the ovarian mechanical microenvironment. Superovulation was performed to observe the number of eggs obtained， as well as the number of offspring and birth weight to assess fertility. The in vitro fertilization and blastocyst culture of oocytes from female offspring in each group were observed to evaluate the effect of WHF on offspring reproductive potential. ResultsCompared with the 3-month group， the 6-month group and 9-month group showed significantly decreased serum levels of gonadotropin-releasing hormone （GnRH）， follicle-stimulating hormone （FSH）， and luteinizing hormone （LH）， decreased ovarian collagen content， and reduced numbers of primordial and secondary follicles. In contrast， the numbers of primary follicles， antral follicles， and atretic follicles increased. The levels of anti-Müllerian hormone （AMH）， ovarian HA content， and the fertilization rate， cleavage rate， and blastocyst formation rate of oocytes from offspring were significantly lower （P＜0.05）. Compared with the 6-month group， the 6-month + WHF group showed significantly reduced serum levels of GnRH， FSH， and LH， with a significant decrease in primary follicles， antral follicles， and atretic follicles as well as increase of AMH levels， ovarian HA content， number of primordial and secondary follicle， egg count， and offspring birth weight （P＜0.05）. Compared with the 9-month group， the 9-month + WHF group exhibited reduced GnRH， FSH， and collagen fiber content， as well as reduced number of primary follicles， antral follicles， and atretic follicles. However， AMH levels， ovarian HA content， number of primordial and secondary follicle， egg count， offspring numbers， birth weight， fertilization rate， cleavage rate， and blastocyst formation rate of oocytes from offspring all significantly increased （P＜0.05）. ConclusionWHF can significantly improve the ovarian reserve， fertility， and reproductive potential in offspring during reproductive mid-life and late-life stages. Its effect may be related to the remodeling of the mechanical microenvironment of aging ovaries. Moreover， the effect on the mechanical microenvironment remodeling of late-stage ovaries and the improvement of the offspring reproductive potential is more significant.

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 establish a full-chain follow-up system for tumor patients during chemotherapy and to evaluate its application effect.Methods A full-chain follow-up system was built according to the actual needs of cancer patients during chemotherapy,including 5 modules:patient health records,follow-up plan,risk identification and abnormal reminder,online consultation,interaction between doctors and patients and data visualization analysis and intelligent statistical management.Convenience sampling method was used to select 96 patients with tumor at chemotherapy stage who were treated in a tertiary A hospital in Deyang City,Sichuan Province from February to June 2023 as a test group,and the full chain follow-up system for tumor patients at chemotherapy stage was applied for follow-up;93 patients with tumor at chemotherapy stage were treated from February to June 2022 as a control group for routine follow-up care.Indicators of self-management ability,quality of life and satisfaction with follow-up services were compared between the 2 groups before and after the application of the system.Results 94 cases in the test group and 92 cases in the control group completed the study.After the application of the system,the test group scored(169.44±11.96)on the Cancer Patients Self-Management Scale,higher than(150.76±13.44)in the control group.The score on the Cancer Patients Quality of Life Core Scale was(65.50±7.90),higher than(59.81±7.27)in the control group.The score on the Questionnaire of Satisfaction with the Follow-Up Service was(52.00±3.30),higher than(48.89±3.54)in the control group,and the difference between the 2 groups was statistically significant(P＜0.001).Conclusion The application of the full-chain follow-up system can meet the diversified and multi-level follow-up needs of tumor patients during chemotherapy,achieve accurate,professional and intelligent nursing follow-up services,effectively improve patients'symptom self-management ability and quality of life,and improve patients'satisfaction with nursing services.

Objective:To assess the current status and influencing factors of cognitive function among the elderly in Hainan Province, providing a basis for developing future intervention strategies to enhance cognitive health.Methods:A cross-sectional study was conducted from August 2021 to June 2022.A total of 2, 059 elderly individuals were selected from 25 counties and cities in Hainan Province through convenience sampling.Data collection utilized the Mini-Mental State Examination(MMSE)and the Activity of Daily Living Scale(ADL). Chi-square tests were conducted for univariate analysis of cognitive impairment, while binary logistic regression was employed to further investigate the factors influencing cognitive function.Results:Among the 2, 059 elderly participants, 609(29.6%)exhibited cognitive impairment.Statistically significant factors identified in the univariate analysis were incorporated into the binary logistic regression model.The results indicated that being female( OR=1.364, 95% CI: 1.091-1.704), aged 70 to 79 years( OR=1.410, 95% CI: 1.070-1.860), aged 80 to 89 years( OR=1.859, 95% CI: 1.386-2.493), aged 90 years or older( OR=2.369, 95% CI: 1.454-3.859), belonging to an ethnic minority( OR=1.405, 95% CI: 1.109-1.779), being widowed( OR=1.372, 95% CI: 1.049-1.794), residing in rural areas( OR=1.411, 95% CI: 1.074-1.856), having three or more chronic diseases( OR=1.887, 95% CI: 1.337-2.662), and experiencing mild( OR=1.695, 95% CI: 1.275-2.252), moderate( OR=2.326, 95% CI: 1.579-3.428), or severe disability( OR=2.873, 95% CI: 1.760-4.691)were identified as risk factors for cognitive impairment in the elderly( P<0.05). In contrast, higher educational attainment was found to be protective, with junior high school education( OR=0.622, 95% CI: 0.511-0.859), high school or technical secondary school education( OR=0.469, 95% CI: 0.327-0.675), and a college education or higher( OR=0.412, 95% CI: 0.264-0.642)serving as protective factors for cognitive function in the elderly( P<0.05). Conclusions:The prevalence of cognitive impairment among the elderly in Hainan Province is moderate.Elderly women, individuals of advanced age, ethnic minorities, those living in rural areas, widowed individuals, individuals with multiple chronic diseases, and those with disabilities are at a higher risk for cognitive impairment.Relevant health departments and healthcare professionals should prioritize these high-risk groups, conduct early cognitive assessments, and implement targeted interventions to enhance cognitive function.
