Effect of 10-year cumulative blood pressure exposure on atherosclerotic cardiovascular disease of different age groups: kailuan cohort study.

Background: The level at which cumulative blood pressure (BP) can increase the risk of ASCVD in different age groups remains unclear. This study aimed to investigate the association of 10-year cumulative BP levels with the long-term risk of ASCVD of different age groups. Methods: Cumulative BP exposure was assessed using the time-weighted average (TWA) BP divided into four BP groups. The participants were also divided into four groups according to their baseline age (<50, 50-59, 60-69, or ≥70 years). The association between TWA BP and the risk of ASCVD was assessed by age group using multivariate Cox models. The China-PAR prediction model was used to assess the ability of TWA BP to predict ASCVD. Results: In the group aged <50 years, the hazard ratios and 95% confidence intervals for the risk of ASCVD were 2.66 (1.04-6.80), 3.38 (1.54-7.43), and 3.13 (1.36-7.24) for the elevated BP, stage 1 hypertension, and stage 2 hypertension groups, respectively, when compared with the normal BP group. There was a significant difference in the risk of ASCVD between the age groups, with participants aged <50 years having the highest risk, followed by those aged 50-59, 60-69, and ≥70 years. Conclusions: The risk of ASCVD with high cumulative BP exposure was age-dependent, with a gradual decrease in risk with increasing age.

Blood-letting therapy combined with Master Tung's Five-tiger Point Scraping (Gua Sha) for patients with hematological malignancy and chemotherapy-induced peripheral neuritis.

OBJECTIVE: To investigate the clinical efficacy of Shixuan and Qiduan blood-letting therapy combined with Master Tung's Five-tiger Point (11.27) Scraping for patients with hematological malignancy and peripheral neuritis. METHODS: A total of 70 patients with hematological malignancy who were admitted to Langfang TCM Hospital between January 2020 and December 2022 for treating chemotherapy-induced peripheral neuritis were enrolled retrospectively. The patients were divided into a single treatment group that received western nutritional interventions alone, and a combined treatment group that underwent additional Traditional Chinese Medicine (TCM) Shixuan and Qiduan blood-letting therapy, along with Master Tung's Five-tiger Point (11.27) Scraping. Statistical analyses were carried out to compare the clinical efficacy of the two treatment plans in the patients. Scores of sensory disturbance rating (SDR), numeric rating scale (NRS) for pain, nail fold microcirculation (NFM) of the infected extremity, and the quality of life (QoL), as well as the motor nerve conduction velocity (MNCV) and sensory nerve conduction velocity (SNCV) of the median and peroneal nerves of patients in both groups were recorded and compared before and after treatment. The incidence rate of adverse events was compared between the two groups. Furthermore, the clinical outcomes of patients in the two groups were followed up and analyzed for correlated factors using univariate and multivariate analyses. RESULTS: The clinical efficacy rate achieved by the combined therapy was 88.57%, significantly higher than 68.57% for patients undergoing single therapy (P=0.041). Moreover, the scores of SDR, pain NRS, QoL, and NFM of the affected extremity, as well as the MNCV and SNCV of patients in the two groups were all improved after treatment, with better improvements in the combined treatment group than in the single treatment group. The incidence rate of adverse events was higher in the single treatment group compared to that of the combined treatment group (17.14% vs. 11.42%) (P=0.466). In addition, during the six-month follow-up period, a total of 27 patients in both groups developed chronic neural disorders. Logistic regression analysis revealed that the MNCV and SNCV of the median and peroneal nerves, together with the duration of chemotherapy, served as independent influencing factors. CONCLUSION: Shixuan and Qiduan blood-letting therapy combined with Master Tung's Five-tiger Point (11.27) Scraping could improve the SDR and pain NRS scores, facilitate the recovery of neural functions, and advance the QoL of patients with chemotherapy-induced peripheral neuritis without increasing the risk of adverse reactions.

Association between living environmental quality and risk of arthritis in middle-aged and older adults: a national study in China.

Background: The association between combined environmental factors and the risk of arthritis is still scarcely studied. The present study performed cross-sectional and cohort studies to explore the association between risk score of living environment quality and the risk of arthritis in middle-aged and older adults in China. Methods: The study was based on China Health and Retirement Longitudinal Study (CHARLS), and it recruited 17,218 participants in the cross-sectional study and 11,242 participants in the seven-year follow-up study. The living environment quality was measured by household fuel types, household water sources, room temperature, residence types, and ambient concentration of PM2.5. Logistic regression and Cox proportional hazard regression models were utilized to examine the association between the living environment quality and the risk of arthritis. Competing risk models and stratified analyses were applied to further verify our results. Results: Compared with individuals in the suitable environment group, people who lived in moderate (OR:1.28, 95%CI: 1.14-1.43) and unfavorable environments (OR:1.49, 95%CI:1.31-1.70) showed higher risks of arthritis when considering the multiple living environmental factors (P for trend <0.001) in the cross-sectional analysis. In the follow-up study, similar results (P for trend = 0.021), moderate environment group (HR:1.26, 95%CI:1.01-1.56) and unfavorable environment group (HR: 1.36, 95%CI: 1.07-1.74), were founded. Conclusion: Inferior living environment might promote the development of arthritis. It is necessary for the public, especially old people, to improve the living environment, which may be the key to the primary prevention of arthritis.

The impact of fasting plasma glucose variability on osteoporotic fractures.

Purpose: To investigate the impact of FPG variability on osteoporotic fractures in the entire community population. Methods: All participants were from the Kailuan Study. Participants completed three consecutive surveys from 2006-2007, 2008-2009, and 2010-2011. We excluded individuals with an osteoporotic fracture in or prior to the index year and those without complete FPG records at the first 3 examinations. All participants were followed from the date of the 3rd examination to the first occurrence of an endpoint event or December 31, 2021. According to the SD of FPG levels, the included subjects were divided into three groups. A Cox proportional hazards model was performed to further analyze the effect of different FPG-SD groups on the risk of osteoporotic fractures. Results: Ultimately, the study population included 57295 participants. During a median follow-up time of 11.00 years, we documented 772 new osteoporotic fracture cases. When evaluating the FPG-SD level as a categorical variable, the HRs for osteoporotic fractures were 1.07 (95% CI: 0.89-1.29) for T2 and 1.32 (95% CI: 1.10-1.60) for T3 when compared with T1. We found that increased FPG variability was associated with a greater risk of osteoporotic fractures in people with diabetes than in those without diabetes (47% vs. 32%). Conclusion: Increased FPG variability was an independent predictor of incident osteoporotic fracture, especially in individuals older than 50 years old, nonobese individuals, diabetes patients, and individuals with positive FPG-SD variability.

Association of the time course of Chinese visceral adiposity index accumulation with cardiovascular events in patients with hypertension.

BACKGROUND: The Chinese visceral adiposity index (CVAI), a simple surrogate measure of visceral fat, is significantly associated with cardiovascular disease (CVD) risk in the general population. This study aimed to evaluate the association of cumulative CVAI (cumCVAI) exposure and its accumulation time course with CVD risk among patients with hypertension. METHODS: This prospective study involved 15,350 patients with hypertension from the Kailuan Study who were evaluated at least three times in the observation period of 2006 to 2014 (2006-2007, 2010-2011, and 2014-2015) and who were free of myocardial infarction and stroke before 2014. The cumCVAI was calculated as the weighted sum of the mean CVAI for each time interval (value × time). The time course of CVAI accumulation was categorized by splitting the overall accumulation into early (cumCVAI06 - 10) and late (cumCVAI10 - 14) accumulation, or the slope of CVAI versus time from 2006 to 2014 into positive and negative. RESULTS: During the 6.59-year follow-up period, 1,184 new-onset CVD events were recorded. After adjusting for confounding variables, the hazard ratios (HRs) and 95% confidence intervals (CIs) for CVD were 1.35 (1.13-1.61) in the highest quartile of cumCVAI, 1.35 (1.14-1.61) in the highest quartile of the time-weighted average CVAI, 1.26 (1.12-1.43) in those with a cumulative burden > 0, and 1.43 (1.14-1.78) for the group with a 10-year exposure duration. When considering the time course of CVAI accumulation, the HR (95% CI) for CVD was 1.33 (1.11-1.59) for early cumCVAI. When considering the combined effect of cumCVAI accumulation and its time course, the HR (95% CI) for CVD was 1.22 (1.03-1.46) for cumCVAI ≥ median with a positive slope. CONCLUSIONS: In this study, incident CVD risk depended on both long-term high cumCVAI exposure and the duration of high CVAI exposure among patients with hypertension. Early CVAI accumulation resulted in a greater risk increase than later CVAI accumulation, emphasizing the importance of optimal CVAI control in early life.

New-onset stroke on the risk of hip fracture: the Kailuan cohort study in China.

PURPOSE: Stroke is a documented risk factor for hip fracture(HF). However, no data is currently available on this issue in mainland China, we therefore assessed the risk of hip fracture after new-onset stroke using a cohort study. METHODS: This study included 165,670 participants without a history of stroke at baseline from the Kailuan study. All participants were followed biennially until December 31, 2021. During follow-up, a total of 8,496 new-onset stroke cases were identified. For each case subject, four control subjects was randomly selected, matched for age (± 1 years) and sex. The final analysis comprised 42,455 pair-matched cases and controls. A multivariate Cox proportional hazard regression model was used to estimate the effect of new-onset stroke on the risk of hip fracture. RESULTS: During an average follow-up of 8.87 (3.94) years, a total of 231 hip fracture cases occurred, 78 cases in the stroke group and 153 cases in the control group, with incidence rates of 1.12 and 0.50 per 1000 person-years, respectively. The cumulative incidence of the stroke group was higher than that of the controls (P < 0.01). The adjusted hazard ratio (95% confidence interval) of hip fractures in the stroke group was 2.35 (1.77 to 3.12) (P < 0.001) to controls. After stratifying by gender, age, and body mass index, the higher risk was revealed in female (HR 3.10, 95 CI: 2.18 to 6.14, P < 0.001), age < 60 years old (HR 4.12, 95% CI: 2.18 to 7.78, P < 0.001), and non-obesity (BMI<28 kg/m2) (HR 1.74, 95% CI:1.31 to 2.31, P < 0.001) subgroup. CONCLUSIONS: Stroke significantly increases the risk of hip fracture, strategy for protecting stroke patients from falls and hip fractures should be emphasized in poststroke long-term management, particularly the female, age < 60 years old, and non-obese patients.

Association of long-term triglyceride-glucose index level and change with the risk of cardiometabolic diseases.

Objective: The triglyceride-glucose (TyG) index is considered as a pivotal factor for various metabolic, cardiovascular, and cerebrovascular diseases. However, there is currently a paucity of relevant studies on the association between long-term level and change of TyG-index and cardiometabolic diseases (CMDs) risk. We aimed to explore the risk of CMDs in relation to the long-term level and change of TyG-index. Methods: Based on the prospective cohort study, a total of 36359 subjects who were free of CMDs, had complete data of triglyceride (TG) and fasting blood glucose (FBG) and underwent four health check-ups from 2006 to 2012 consecutively were followed up for CMDs until 2021. The associations between long-term level and change of TyG-index and CMDs risk were assessed by Cox proportional hazards regression models to compute hazard ratios (HRs) and 95% confidence intervals (CIs). The TyG-index was calculated as ln [TG, mg/dL) × FBG, mg/dL)/2]. Results: During the median observation period of 8 years, 4685 subjects were newly diagnosed with CMDs. In multivariable-adjusted models, a graded positive association was observed between CMDs and long-term TyG-index. Compared with the Q1 group, subjects with the Q2-Q4 group had increased progressively risk of CMDs, with corresponding HRs of 1.64(1.47-1.83), 2.36(2.13-2.62), 3.15(2.84-3.49), respectively. The association was marginally attenuated, after further adjustment for the baseline TyG level. In addition, compared with stable TyG level, both loss and gain in TyG level were associated with increased CMDs risk. Conclusions: Long-term elevated level and change of TyG-index are risk factors for the incident CMDs. Elevated TyG-index in the early stage remains to exert cumulative effects on the occurrence of CMDs even after accounting for the baseline TyG-index.

Pulse Pressure Variability and the Risk of Fragility Fracture: The Kailuan Prospective Cohort Study in China.

OBJECTIVES: To investigate the association of the magnitude and direction of pulse pressure variability (PPV) with the incidence of fragility fracture in the general population. METHODS: This prospective cohort study included current Kailuan Group employees and retirees who attended health checkups continuously from 2006 to 2010 and were followed up until December 31, 2021. A total of 56,129 individuals who completed the health checkups were selected and grouped according to coefficient of variation (CV) quartile for PPV. The standard deviation (SD) and variability independent of the mean were also calculated as measures of PPV. The cumulative incidence of fragility fracture in the four groups was calculated and the impact of PPV on the risk of fragility fracture was analyzed using a multivariate Cox regression model. The direction of the variation was also assessed. RESULTS: There were 671 cases of fragility fracture (1.2%) during a median follow-up of 11 years. In the multivariable-adjusted model, the hazard ratio for fragility fracture was 1.37 (95% confidence interval 1.11-1.70) for the highest CV quartile for PPV versus the lowest CV quartile for PPV. There was a linear association between higher PPV and fragility fracture. Consistent results were noted for higher PPV and the risk of fragility fracture using other indices of variability and in various sensitivity and subgroup analyses. CONCLUSIONS: High PPV was associated with a higher rate of fragility fracture independently of blood pressure. Reduction of PPV may help to prevent fragility fractures in the general population.

The effect of arteriosclerosis on new-onset renal damage in diabetic patients.

The aim of this study was to investigate the effect of arteriosclerosis on new-onset renal damage in a Chinese community population with diabetes. Patients with diabetes who had attended at least one physical examination after the Brachial-ankle pulse wave velocity (BaPWV) test from 2010 to 2018 were selected as subjects. A total of 4,462 patients were included in the study cohort. BaPWV levels <1,400 cm/s, 1,400-1,799 cm/s, and ≥1,800 cm/s were applied to divide the subjects into a normal arterial stiffness group, borderline atherosclerosis group and atherosclerosis group. Renal damage was defined by isolated proteinuria, isolated eGFR <60 mL/min/1.73 m2, proteinuria and eGFR <60 mL/min/1.73 m2. A Cox proportional risk model was used to analyze the effect of different groups on new-onset renal damage. After a median follow-up of 2.85 (1.88-4.90) years, Cox proportional risk models showed that after adjusting for risk factors, compared with the normal group, the HR and 95% CI of the risk of new-onset renal damage were 1.29 (95% CI: 0.95-1.76) and 1.59 (95% CI: 1.14-2.22) in the borderline atherosclerosis group and the atherosclerosis group, respectively. Atherosclerosis is a risk factor for new-onset renal damage, especially new-onset proteinuria, in diabetic patients.

Effects of mindfulness decompression therapy combined with transcranial magnetic stimulation in generalized anxiety disorder.

OBJECTIVE: To explore the clinical effects of mindfulness decompression therapy combined with transcranial magnetic stimulation in generalized anxiety disorder. METHODS: In the present prospective study, ninety-two patients with generalized anxiety disorder were randomly divided into two groups, with 46 cases in each group. On the basis of drug treatment, patients in the control group received transcranial magnetic stimulation, and patients in the research group were treated with mindfulness decompression therapy combined with transcranial magnetic stimulation. The total effective rate, anxiety degree (evaluated by the Hamilton Anxiety Scale (HAMA) score), severity of condition (evaluated by the clinical global impression (CGI) score), comfort degree score (Psychology, physiology, environment, social culture), neuroelectrophysiological parameters and sleep quality (Pittsburgh sleep quality index (PSQI) factors) before and after treatment were compared between the two groups. RESULTS: After treatment, the research group had higher total effective rate than that of the control group (P<0.05); the HAMA score and CGI score of two groups were both decreased, and the research group decreased much more than the control group (P<0.05); mismatch negativity (MMN) latency, target N2 latency and target P3 latency of two groups were all decreased, MMN amplitude and none-target P2 amplitude were both increased, and the research group improved much more than the control group (P<0.05); the scores of social comfort, environmental comfort, physiological comfort and psychological comfort of two groups were all increased, and the corresponding scores of the research group were all higher than those of the control group (P<0.05); PSQI scores of two groups were all decreased, and the research group had lower PSQI scores than the control group (P<0.05). CONCLUSION: Mindfulness decompression therapy combined with transcranial magnetic stimulation effectively relieve anxiety symptoms and improve comfort degree and sleep quality in patients with generalized anxiety disorder.

Microarray Analysis of the Major Depressive Disorder mRNA Profile Data.

OBJECTIVE: Major depressive disorder (MDD) is a common mood disorder associated with several psychophysiological changes like disturbances of sleep, appetite, or sexual desire, and it affects the patients' life seriously. We aimed to explore a genetic method to investigate the mechanism of MDD. METHODS: The mRNA expression profile (GSE53987) of MDD was downloaded from Gene Expression Omnibus database, including 105 samples of three brain regions in post-mortem tissue suffered from MDD and unaffected controls. Differentially expressed genes (DEGs) in MDD were identified using the Limma package in R. Gene Ontology functions and Kyoto Enrichment of Genes and Genomes pathways of the selected DEGs were enriched using Database for Annotation, Visualization and Integrated Discovery. Protein-protein interactive network of DEGs was constructed using the Cytoscape software. RESULTS: Totally, 241 DEGs in MDD-hip group, 218 DEGs in MDD-pfc group, and 327 DEGs in MDD-str group were identified. Also, different kinds of biological processes of DEGs in each group were enriched. Besides, glycan biosynthesis of DEGs in MDD-str group, RIG-I-like receptor signaling and pyrimidine metabolism of DEGs in the MDD-hip group were enriched, respectively. Moreover, several DEGs like PTK2, TDG and CETN2 in MDD-str group, DCT, AR and GNRHR in MDD-pfc group, and AKT1 and IRAK1 in MDD-hip group were selected from PPI network. CONCLUSION: Our data suggests that the brain striatum tissue may be greatly affected by MDD, and DEGs like PTK2, GALNT2 and GALNT2 in striatum, AR in prefrontal cortex and IRAK1 and IL12A in hippocampus may provide novel therapeutic basis for MDD treatment.
