BACKGROUND: Early control of low-density lipoprotein cholesterol (LDL-C) is crucial for reducing the progress of cardiovascular disease. However, its additional role to the risk of primary osteoporosis in men with coronary heart disease was inconclusive. Our study aims to determine the association of LDL-C and its trajectories for osteoporosis risk in the middle-aged and aged men of China. METHODS: The retrospective cohort study of 1546 men aged 69.74 ± 11.30 years conducted in Beijing, China from 2015 to 2022. And the incidence of primary osteoporosis was annually recorded. LDL-C trajectories were further identified by latent class growth model using repeated measurements of LDL-C. The association of baseline LDL-C for osteoporosis was estimated using hazard ratio (HR) with 95% CI in Cox proportional hazard model, while mean level and trajectories of LDL-C for osteoporosis were evaluated using odds ratio (OR) with 95% CI in logistic regression model. RESULTS: During the median 6.2-year follow-up period, 70 men developed primary osteoporosis. The higher level of baseline LDL-C (HR = 1.539, 95% CI: 1.012-2.342) and mean LDL-C (OR = 2.190, 95% CI: 1.443-3.324) were associated with higher risk of osteoporosis in men with coronary heart disease after adjusted for covariates. Compared with those in the LDL-C trajectory of low-stable decrease, participants with medium-fluctuant trajectory, whose longitudinal LDL-C started with a medium LDL-C level and appeared an increase and then decrease, were negatively associated with osteoporosis risk (OR = 2.451, 95% CI: 1.152-5.216). And participants with initially high LDL-C level and then a rapid decrease demonstrated a tendency towards reduced risk (OR = 0.718, 95% CI: 0.212-2.437). CONCLUSIONS Elevated LDL-C level and its long-term fluctuation may increase the risk of primary osteoporosis in men. Early controlling a stable level of LDL-C is also essential for bone health.

OBJECTIVE: To investigate whether Buyang Huanwu Decoction (BYHWD) had a good curative effect on the neuroprotection of red nucleus neurons after spinal cord injury (SCI) and the possible molecular mechanism. METHODS: Ninety male Sprague-Dawley rats were divided into 5 groups (n=18 per group) according to a random number table, including the control, model, low- (12.78 g/kg, BL group), medium- (25.65 g/kg, BM group), and high-dose BYHWD groups (51.30 g/kg, BH group). A rubrospinal tract transection model in rats was established, and different doses of BYHWD were intragastrically administrated for 4 weeks. The forelimb locomotor function was recorded using the spontaneous vertical exploration test. Cyclic adenosine monophosphate (cAMP) level in red nucleus was detected through an enzyme-linked immunosorbent assay. The morphology and number of red nucleus neurons were observed using Nissl's staining and axonal retrograde tracing by Fluoro-Gold (FG). The expression of cAMP-dependent protein kinase A (PKA), nuclear factor kappa-B (NF-κB) p65, and brain-derived neurotrophic factor (BDNF) in red nucleus were detected using immunohistochemistry and quantitative real-time polymerase chain reaction. RESULTS: Compared with the control group, the utilization rate of bilateral forelimbs, unilateral right forelimbs, proportion of FG-labeled positive neurons, cAMP level, protein expressions of PKA and BDNF, and BDNF mRNA expression were significantly decreased in the model group (P<0.01), while NF-κB p65 was increased in the model group (P<0.01). Compared with the model group, the utilization rate of bilateral forelimbs and unilateral right forelimbs were significantly higher in the BL, BM and BH groups (P<0.01), the proportion of FG-labeled positive neurons, cAMP level, protein expressions of PKA and BDNF and BDNF mRNA expression in all BYHWD groups were increased (P<0.05 or P<0.01), while NF-κB p65 were decreased in all BYHWD groups (P<0.05 or P<0.01). CONCLUSIONS BYHWD possesses a sound neuroprotective effect on red nucleus neurons after SCI, and the efficacy was dose-related. The mechanism may be related to regulating the cAMP/PKA/NF-κ B p65 signaling pathway, finally promoting expression of BDNF.

Objective To improve the efficiency of hospital antimicrobial management and ensure rational clinical use of antimicrobial agents with the aid of antimicrobial stewardship(AMS)empowered by digital intelligence tech-nology in hospital.Methods Information systems such as early warning of antimicrobial indexes,closed-loop ma-nagement of microbial detection information,and decision-making system of antimicrobial resistance monitoring data were applied to the traditional AMS system.Through hospital information systems(HIS)to collect data about thera-peutic antimicrobial use and healthcare-associated infection(HAI)quality control indexes of hospitalized patients in a tertiary first-class public hospital in Shenzhen City before and after digital technology improvement,indexes of 2021 and 2022 were as control group(before improvement)and observation group(after improvement)respective-ly,improvement trend of antimicrobial management was compared.Results After upgrading and renovating the hospital information system,hospital antimicrobial management indexes improved significantly compared to before the renovation.The use rate of antimicrobial agents and the preventive use rate of antimicrobial agents in class Ⅰincision surgery in patients in the observation group were both lower than those in the control group(27.0％vs 38.8％,20.9％vs 23.8％,respectively,both P＜0.05).Antimicrobial use density in hospitalized patients in the observa-tion group was lower than that in the control group([33.27±3.03]DDDs vs[42.06±4.42]DDDs),difference was statistically significant(t=13.11,P＜0.001).The observation group had a higher qualified rate for evaluating antimicrobial medical orders compared to the control group(98.5％vs 96.8％).The pathogenic detection rate of hospitalized patients before therapeutic antimicrobial use and pathogen detection rate related to HAI diagnosis were both higher than those in the control group(87.1％vs 84.5％,99.0％vs 95.4％,respectively),differences were both statistically significant(both P＜0.05).Conclusion Empowering the hospital's AMS system with digital technology can promote more scientific,standardized,efficient,and rational antimicrobial management in hospitals.

Objective This study aimed to investigate the potential relationship between urinary metals copper (Cu), arsenic (As), strontium (Sr), barium (Ba), iron (Fe), lead (Pb) and manganese (Mn) and grip strength. Methods We used linear regression models, quantile g-computation and Bayesian kernel machine regression (BKMR) to assess the relationship between metals and grip strength.Results In the multimetal linear regression, Cu (β=-2.119), As (β=-1.318), Sr (β=-2.480), Ba (β=0.781), Fe (β= 1.130) and Mn (β=-0.404) were significantly correlated with grip strength (P < 0.05). The results of the quantile g-computation showed that the risk of occurrence of grip strength reduction was -1.007 (95％ confidence interval:-1.362, -0.652; P < 0.001) when each quartile of the mixture of the seven metals was increased. Bayesian kernel function regression model analysis showed that mixtures of the seven metals had a negative overall effect on grip strength, with Cu, As and Sr being negatively associated with grip strength levels. In the total population, potential interactions were observed between As and Mn and between Cu and Mn (Pinteractions of 0.003 and 0.018, respectively).Conclusion In summary, this study suggests that combined exposure to metal mixtures is negatively associated with grip strength. Cu, Sr and As were negatively correlated with grip strength levels, and there were potential interactions between As and Mn and between Cu and Mn.

Objective:To investigate the influencing factors for the training quality of clinical pharmacy undergraduates in China from multiple dimensions and the problems existing in the current training model, to propose suggestions for improvement, and to provide a reference for improving the training quality of clinical pharmacy undergraduates in China.Methods:Four dimensions of vital importance to the training quality of clinical pharmacy undergraduates in China were summarized based on the results of previous literature research and semi-structured interviews, and a questionnaire was designed to conduct a survey among clinical pharmacy undergraduates. Then based on the problems obtained through feedback, an investigation was conducted among the clinical pharmacists in various provinces across the country. SPSS 25.0 was used to perform a statistical analysis.Results:The influencing factors for the cultivation and development of clinical pharmacy undergraduates included insufficient awareness of their major [18.28% (17/93) of the senior and graduate students still had no understanding or relatively little understanding of their major], a lack of specialty characteristics in undergraduate education of clinical pharmacy [35.91% (107/298) of the students thought that the arrangement of public courses during the undergraduate period of clinical pharmacy was unreasonable or needed improvement], unreasonable arrangement of the contents and time of internship [34.23% (102/298) of the students thought that the experiment and internship arrangement during the undergraduate period of clinical pharmacy was unreasonable or needed to be improved], and inadequate cultivation of learning and scientific research innovation abilities [66.78% (199/298) of the students had not participated in scientific research projects or training, with σ>1 in the statistics of various learning behaviors]. Conclusions:Professional cognition and internship/practice should be taken seriously in the training system of clinical pharmacy undergraduates. Curriculum setting should be optimized to enhance specialty characteristics, and the teaching and training model should be improved to focus on ability training.

OBJECTIVE: To compare the curative effect between interactive scalp acupuncture and traditional scalp acupuncture on hemiplegic upper extremity motor dysfunction in the patients with ischemic stroke. METHODS: Seventy cases of hemiplegic upper extremity motor dysfunction of ischemic stroke were randomly divided into an interactive scalp acupuncture group (35 cases, 1 case breaked off) and a traditional scalp acupuncture group (35 cases, 1 case dropped off). The patients of the two groups received the secondary prevention medication and routine rehabilitation therapy. Besides, in the interactive scalp acupuncture group, the upper extremity occupational therapy was operated during the needle retaining of scalp acupuncture; and in the traditional scalp acupuncture group, the upper extremity occupational therapy was delivered after the completion of scalp acupuncture. The same points were selected in the two groups such as Fuxiang head area, Fuxiang upper-limb-shoulder point, Fuxiang upper-limb-elbow point and Fuxiang upper-limb-wrist point. The needles were inserted perpendicularly by flying-needle technique and manipulated by triple technique of gentle twisting, heavy pressure and vibrating. The needles were retained for 30 min. Based on the degree of the upper extremity motor impairment, the regimen of the upper extremity occupational therapy was formulated individually and one treatment took 30 min. In the two groups, the therapies were delivered once daily, 5 times a week, lasting 4 weeks. Before and after treatment, the scores of Fugl-Meyer assessment of upper extremity (FMA-UE), Wolf motor function test (WMFT), the modified Barthel index (MBI) and the modified Ashworth scale (MAS) grade in the two groups were observed before and after treatment. RESULTS: After treatment, the scores of FMA-UE, WMFT and MBI were higher than those before treatment (P<0.01), and MAS grade was improved (P<0.05) in the two groups. The scores of FMA-UE, WMFT and MBI in the interactive scalp acupuncture group were higher than those in the traditional scalp acupuncture group (P<0.01, P<0.05), and there was no statistical significance in the difference of MAS grade between the two groups (P>0.05). CONCLUSION The interactive scalp acupuncture can effectively improve the motor function of the hemiplegic upper extremities and the activities of daily living in the patients with ischemic stroke and its efficacy is better than traditional scalp acupuncture. But these two types of scalp acupuncture obtain the similar effect on spasticity.
