OBJECTIVE To provide a reference for improving postoperative pain management outcomes， accelerating patient recovery， and ensuring the safe use of opioids. METHODS A prospective cohort study was conducted， in which patients undergoing elective hip or knee replacement in the Department of Orthopedics at Baoding No.1 Central Hospital （hereinafter referred to as “our hospital”） from November 2021 to November 2023 were randomly divided into control group and observation group using a random number table， with 178 cases in each group. Patients in the control group received postoperative pain management implemented by medical staff according to the clinical pathway for perioperative pain treatment. Patients in the observation group， under the enhanced recovery after surgery model， received postoperative pain management through a multidisciplinary collaborative team including clinical pharmacists. The occurrence and resolution of opioid-related drug-related problems （DRPs） were compared between the two groups， and the DRPs were classified and analyzed using the Pharmaceutical Care Network Europe Classification System （V9.1）. Postoperative pain scores， sleep quality scores， length of hospital stay， and incidence of adverse reactions were compared between the two groups. RESULTS A total of 162 opioid-related DRPs were identified in 2 groups， with 58 in the observation group （identified 52 patients） and 104 in the control group （identified 91 patients）， showing a statistically significant difference （P＜0.05）. The primary issue involved in the DRPs for both groups was therapeutic effectiveness. Clinical pharmacists in the observation group conducted 88 interventions for the identified 58 opioid-related DRPs， achieving an overall intervention success rate of 84.5%. The pain scores and sleep quality scores from postoperative day 1 to 7， the length of hospitalization for hip replacement， the average hospitalization duration， and the total incidence of opioid-related adverse reactions were all significantly lower or shorter in the observation group compared to the control group （P＜0.05）. Furthermore， the main time effect， time-group interaction effect for pain scores and sleep quality scores were statistically significant in both groups （P＜0.05）， indicating that the control group exhibited greater reductions in these scores and observation group exhibited more rapid improvements. CONCLUSIONS The full involvement of clinical pharmacists in postoperative pain management and opioid medication administration in the orthopedics department enables timely identification and intervention of DRPs， enhance postoperative analgesia efficacy， decrease adverse drug reactions， shorten hospital stays， and accelerate patient recovery.

ObjectiveTo unearth novel circRNA-miRNA-mRNA network and potential drugs in ischemic stroke. MethodsData from the GEO database were utilized， focusing on three datasets （GSE115697， GSE51586， and GSE137482） that examine RNA expression levels in middle cerebral artery occlusion （MCAO） mouse models. Differentially expressed mRNA （DEmRNA）， DEcircRNA， and DEmiRNA were identified using the Limma package in R. A comprehensive strategy combining bioinformatics tools such as MiRWalk and StarBase was employed to identify circRNA-miRNA-mRNA networks associated with ischemic stroke. Hub sub-networks were screened and visualized using Cytoscape software. Functional analyses of the ceRNA networks were performed using Gene Ontology （GO） enrichment and Kyoto Encyclopedia of Genes and Genomics （KEGG） pathway analysis， with pathways containing more than 10 enriched genes and an false discovery rate （FDR） ＜ 0.05 considered statistically significant. Lastly， the Connectivity Map （CMap） was applied to identify potential therapeutic drugs for ischemic stroke and the MCAO model was established in wild-type mice to verify the therapeutic effect. ResultsTotally， 1，249 DEmRNA， 294 DEmiRNA and 70 DEcircRNA were identified and it was found that 3 circRNA-miRNA-mRNA networks might be closely related to ischemic stroke. Based on these findings， Austricine， Metyrapone and Desoxypeganine were the most likely drugs that able to reverse the changes caused by stroke-related ceRNA networks. Metyrapone， taken as an example， was validated to improve neurological function damage on the first （P=0.001 4） and second （P=0.016 1） days post-surgery and reduce infarct volume （P=0.004 9）， thereby exerting a neuroprotective effect in ischemic stroke. ConclusionsOur study provides a novel insight into the pathogenesis and therapy of ischemic stroke from the perspective of circRNA-miRNA-mRNA regulatory network. The three drugs predicted in our research provide new clues for the treatment of ischemic stroke.

convalescents, and to screen for broad-spectrum neutralizing antibodies against the SARS-CoV-2 RBD. Methods Using biotinylated RBD as a molecular probe, flow cytometry was employed to perform single-cell sorting of B cells from peripheral blood mononuclear cells (PBMCs) of convalescents. The obtained B cells were lysed and subjected to reverse transcription, followed by nested PCR amplification of the heavy and light chains of antibodies was conducted using random primers. The amplified products were cloned into corresponding expression vectors, and the respective matched heavy-light chain plasmids were co-transfected into 293F cells for expression. Monoclonal antibodies were then purified using Protein A column chromatography. Neutralization experiments were conducted with the wild-type (WT) pseudovirus, and antibodies with IC50<0.1 μg/mL were selected for further testing of neutralizing breadth and potency against the wild-type (WT), Beta variant (B.1.351), Delta variant (B.1.617.2), and currently prevalent pseudovirus strains (XBB, BA.5, BF.7). Results A total of 21 RBD-specific monoclonal B cells were obtained from two recovered patients, resulting in the isolation of 13 pairs of antibody light/heavy chains. Nine antibodies were successfully expressed, with P1-A1, P1-B6, and P1-B9 exhibiting IC50 values below 0.1 μg/mL against the pseudovirus of the wild-type strain (WT). Specifically, P1-B6 effectively neutralized the wild-type strain (WT), Beta variant (B.1.351), and Delta variant (B.1.617.2), with IC50 values reaching 0.01 μg/mL. P1-B9 demonstrated effective neutralization against the wild-type strain (WT), Beta variant (B.1.351), Delta variant (B.1.617.2), and Gamma variant (P.1) pseudoviruses, with IC50 values of 0.42 μg/mL, 0.63 μg/mL, 0.28 μg/mL, and 2.50 μg/mL, respectively. Additionally, P1-B6 exhibited good neutralization against BA.5 and BF.7 pseudoviruses, with IC50 values of 0.06 μg/mL and 0.09 μg/mL, respectively. Conclusions Infection with the SARS-CoV-2 WT strain can induce the generation of neutralizing antibodies with broad-spectrum activity. Generating these broadly neutralizing antibodies does not require an excessively high somatic hypermutation. The obtained antibodies can be used as candidates for SARS-CoV-2 diagnosis and prevention.

Under the backdrop of the "Healthy China 2030" strategy, running has become the most common form of exercise. Fitness running is a kind of endurance aerobic exercise. Compared with swimming, aerobics, and other sports with high activity and intensity, the risk of lower limb fatigue injury during fitness running is higher. In this review paper, the risk factors for running-related injuries were summarized by consulting and analyzing the database and focuses on discussing and analyzing the impact of running on joints. The results showed that hip adduction, knee bending, and ankle joint abnormalities are the three joint-related factors that cause the main injuries during running. Four rehabilitation intervention methods for running-related injuries were proposed, that can guide patients to generate personalized rehabilitation treatment plans through training.

Objective:To investigate the prevalence of frailty among elders aged ≥60 years in the Beijing community and analyze the risk factors of frailty.Methods:This is a cross-sectional study. A total of 1936 older persons in Baizhifang Community in Beijing were included between May and September 2023. Their frailty was evaluated by Fried Frailty Phenotype Scale. Mini Nutritional Assessment-Short Form (MNA-SF), Short Physical Performance Battery (SPPB), and Geriatric Depression Scale (GDS) were used to evaluate nutritional status, physical function, and depression, respectively. The prevalence and risk factors of frailty among the elderly in the community were analyzed.Results:A total of 168 individuals met the criteria for frailty, and the prevalence of frailty was 8.7%. Compared to the non-frail group, the frail group was predominantly female (71.4% vs 62.2%; χ 2=5.59, P=0.018), older [(72.1±6.6) vs (69.9±6.0) ages; t=-5.25, P<0.001], unmarried (1.8% vs 0.8%; χ 2=8.60, P=0.014), with lower education levels (10.7% vs 3.5%; χ 2=23.38, P<0.001), poorer self-assessed health (22.6% vs 6.5%; χ 2=69.80, P<0.001), lower MNA-SF scores [(12.2±2.2) vs (13.0±1.4) scores; t=6.29, P<0.001], lower SPPB scores [(8.4±1.9) vs (10.2±1.6) scores; t=14.62, P<0.001], higher GDS scores [(4.0±3.8) vs (1.9±2.1) scores; t=-11.48, P<0.001], and worse vision, hearing, and olfactory functions (48.2% vs 34.1%, 36.9% vs 23.0%, 9.5% vs 3.0%; χ 2=13.37, 16.11, 40.58, all P<0.001). They were also more likely to suffer from hypertension (70.8% vs 56.7%; χ 2=12.52, P<0.001), diabetes (42.3% vs 29.4%; χ 2=12.06, P<0.001), osteoarthritis (46.4% vs 30.3%; χ 2=18.39, P<0.001) and stroke (19.0% vs 13.3%; χ 2=4.28, P=0.039). Logistic regression analysis showed that frailty was independently associated with nutritional status ( OR=0.8, 95% CI: 0.7-0.9, P<0.001), depressive symptoms ( OR=1.1, 95% CI: 1.1-1.2, P<0.001), olfactory function ( OR=2.1, 95% CI: 1.4-3.0, P<0.001; OR=2.9, 95% CI: 1.4-5.9, P=0.003), and physical function ( OR=0.6, 95% CI: 0.6-0.7, P<0.001) after adjusting for covariates. Conclusions:The prevalence of frailty among elderly people in community is relatively high. Frailty in community elders is associated with physical function, psychological function, nutritional status, and olfactory function decline.

Objective:To analyze mobility limitation condition and its relationship with cognitive function in community-dwelling elderly.Methods:In this cross-sectional study, a total of 1 935 older adults aged≥60 years were recruited from May to September 2023 in Beijing Baizhifang Community Health Service Center and its five subordinate health service stations (Baizhifang Hutong health service station, Nancaiyuan community health service station, Youanmen community health service station, Younei West Street health service station and Shuanghuaili community health service station). The Short Physical Performance Battery (SPPB) was used to assess the mobility capacity of the elderly, and the elderly were divided into two groups with SPPB, the elderly with a SPPB≤9 points were grouped into mobility limitation group (645 cases), and the ones with a SPPB≥10 points were considered with normal mobility capacity (1 290 cases). The cognitive function of the older adults was assessed with the mini-mental state examination; and the gender, age, calf circumference, history of chronic disease, frailty status, cognitive function, nutritional status, depression status, hearing and vision condition of the two groups were compared with χ2 test or Mann-Whitney U non-parametric test. Multiple logistic regression analysis was used to analyze the mobility limitation and its relationship with cognitive function in the older adults. Results:Mobility limitation was found in 33.33% (645/1 935) of community-dwelling older adults. The proportions of advanced age, female, hypertension, diabetes, coronary heart disease, stroke, chronic obstructive pulmonary disease, frailty, depression, cognitive impairment, hearing decline, and vision decline in the mobility limitation group were all significantly higher than those in the normal mobility capacity group (31.32% vs 13.41%, 69.92% vs 59.61%, 65.27% vs 54.03%, 33.80% vs 28.60%, 27.91% vs 19.53%, 17.83% vs 11.47%, 10.54% vs 7.36%, 13.18% vs 2.02%, 18.45% vs 6.59%, 14.73% vs 7.75%, 30.54% vs 20.31%, 45.58% vs 30.39%) (all P<0.05). Advanced age ( OR=2.542, 95% CI: 1.977-3.269), female ( OR=1.736, 95% CI: 1.390-2.167), stroke ( OR=1.426, 95% CI: 1.065-1.911), depression ( OR=2.292, 95% CI: 1.656-3.174), cognitive impairment ( OR=1.601, 95% CI: 1.154-2.220), frailty ( OR=5.199, 95% CI: 3.219-8.397) and vision decline ( OR=1.405, 95% CI: 1.124-1.756) were all positively correlated with the mobility limitation in the community-dwelling older adults (all P<0.05). Conclusion:The older adults in the community have a higher risk of mobility limitation, mobility limitation is a positive correlation factor of cognitive impairment.

Objective:To investigate diagnostic and prognostic value of actin-binding protein ANLN in clear cell renal cell carcinoma(ccRCC)and its relationship with tumor microenvironment.Methods:Gene expression data and clinical data for ccRCC were downloaded from The Cancer Genome Atlas(TCGA).Relationship between ANLN expression and clinicopathological features was assessed by Wilcoxon rank sum test and Logistic regression.Receiver operating characteristic(ROC)curve was used to assess diagnostic value of ANLN expression in ccRCC.Kaplan-Meier and Cox regression analysis were used to investigate effect of ANLN expression on overall survival.Gene set enrichment analysis(GSEA)was used to identify signaling pathways associated with ANLN in ccRCC.Relationship between ANLN expression and immune infiltration was analyzed by ESTIMATE algorithm,tumor immune estima-tion resource(TIMER)and CIBERSORT algorithms.Relationship between ANLN and drug sensitivity was calculated using CellMiner database.Results:ANLN expression was significantly upregulated in ccRCC tissues.ANLN expression in ccRCC was correlated with clinicopathological features.ROC analysis showed that ANLN had a high diagnostic value in ccRCC.High ANLN expression was signifi-cantly associated with poor prognosis.Multivariate Cox regression analysis showed that high ANLN expression was an independent risk factor for overall survival in ccRCC patients.GSEA showed that ANLN was associated with multiple signaling pathways.In terms of immunity,ANLN was closely associated with tumor microenvironment,immune infiltration and immune checkpoint molecules in ccRCC.ANLN expression was negatively correlated with sensitivity of most antitumor drugs.Conclusion:ANLN is a potential diagnos-tic and prognostic biomarker and immunotherapeutic target for ccRCC.

OBJECTIVE To explore the mechanism by which gastrodin improves renal hyperten-sion in rats.METHODS A rat model of renal hypertension was established by ligating the renal artery.seventy-five rats were randomly divided into 5 groups(n=15):control group(sham operation group),model group,model+ramipril 1 mg·kg-1,model+gastrodin 100 and 200 mg·kg-1.The systolic blood pressure of the tail artery after modeling>18.12 kPa was regarded as the success of modeling.After the model was established,rats in the model+ramipril group were ig given ramipril 1 mg·kg-1 while the model+gastrodin group was ig given gastrodin 100 and 200 mg·kg-1 respectively for 4 weeks.Colori-metric assay kit was used to detect the serum superoxide dismutase(SOD)activity and malondialde-hyde(MDA)content in rats.ELISA was used to detect serum angiotensin-2(Ang-2)and aldosterone(ALD)contents,as well as serum and thoracic aortic tissue interleukin-1β(IL-1β),IL-6 and tumor necrosis factor α(TNF-α)content.HE staining was performed to detect pathological changes in thoracic aorta tissue of rats.The expressions of autophagy protein miceotubule associated protein light chain 3(LC3)-Ⅱand LC3-Ⅰwere detected by Western blotting.RESULTS The systolic pressure of the tail artery of rats after modeling exceeded 18.12 kPa,indicating that the modeling was successful.Compared with the control group,the contens of Ang-2(P<0.01)and ALD(P<0.01)in the model group were significantly increased,the activity of SOD(P<0.01)in serum and thoracic aorta tissue was significantly decreased,the content of MDA(P<0.01)was significantly increased,the contents of IL-1β,IL-6 and TNF-α in serum and thoracic aorta tissue were significantly decreased(P<0.01)and the ratio of LC-32/LC-31 in thoracic aorta tissue was significantly increased(P<0.01).Compared with the model group,gastrodin significantly increased the systolic pressure of the tail artery(P<0.01),the contents of Ang-2(P<0.01)and ALD(P<0.01)and the activity of SOD(P<0.01)in serum,as well as decreased the contents of MDA,IL-1β,IL-6 and TNF-α(P<0.01)in serum and thoracic aorta tissue.Meanwhile,gastrodin signifi-cantly decreased the ratio of LC3-Ⅱ/LC3-Ⅰ in rat thoracic aorta(P<0.01).CONCLUSION Gastrodin can improve the blood pressure of renal hypertensive rats,and the mechanism is possibly related to the reduction of autophagy protein LC3-Ⅱ/LC3-Ⅰratio.

Objective:To observe the effects of nutritional status on the surgical outcomes, nutritional indicators, and renal anemia of maintenance hemodialysis patients with secondary hyperparathyroidism undergoing parathyroidectomy.Methods:A retrospective study was conducted on 35 patients who underwent maintenance hemodialysis with secondary hyperparathyroidism at Huadu District People′s Hospital of Guangzhou from January 2016 to January 2021. All patients underwent total parathyroidectomy with autologous forearm transplantation due to ineffective drug treatment. Before surgery, patients were divided into three groups based on their nutritional status scores: no malnutrition group (0-1 points), mild malnutrition group (2-4 points), and moderate to severe malnutrition group (5-12 points). The changes in serum parathyroid hormone, blood calcium, blood phosphorus, blood albumin, and other indicators were observed at different time points before and after surgery in different groups of patients.Results:The serum parathyroid hormone, blood phosphorus, and calcium phosphorus product of maintenance hemodialysis patients with different nutritional status who underwent parathyroidectomy at 3, 6, and 12 months were significantly decreased compared with preoperative levels, and the differences were statistically significant (all P<0.05). There were no significant changes in albumin, lymphocyte count, and total cholesterol levels in patients without malnutrition at 3, 6, and 12 months after surgery compared with preoperative levels (all P>0.05); The lymphocyte count of patients with mild malnutrition increased significantly at 6 and 12 months after surgery compared to preoperative levels (all P<0.05). The levels of albumin and total cholesterol in patients with moderate to severe malnutrition increased significantly at 3, 6, and 12 months after surgery compared with preoperative levels (all P<0.05). The Hb levels of patients without malnutrition and those with mild malnutrition increased significantly at 6 and 12 months after surgery compared with preoperative levels (all P<0.05); The Hb levels of patients with moderate to severe malnutrition increased significantly at 3, 6, and 12 months after surgery compared with preoperative levels (all P<0.05). Conclusions:Nutritional status affects the long-term outcomes of parathyroidectomy in hemodialysis patients, and parathyroidectomy can significantly improve the nutritional and anemia status of hemodialysis patients with secondary hyperparathyroidism. This effect is more pronounced in patients with moderate to severe malnutrition before surgery.
