Objective To analyze the distribution status of the end digits of standardized blood pressure measurement recordings in the clinic and the effectiveness of standardized blood pressure measurement for community hypertension screening. Methods The first visit blood pressure measurement data from the Community Health Service Center in Jing'an District, Shanghai from June 2023 to May 2024 were collected and analyzed. According to different measurement methods, the data were divided into two groups: standardized blood pressure measurement and conventional blood pressure measurement. SPSS 19.0 software was used for data analysis. The differences in the distribution balance of the end digits of blood pressure values and the detection rate of blood pressure elevation between the two different groups were analyzed. Results The frequency range of the end digits of blood pressure recorded values in the standardized pressure measurement group was 9.42% to 10.83%, and the detection rate of elevated blood pressure was 24.89%. The conventional pressure measurement group had a preference of the end digit ^"0^", and the detection rate of elevated blood pressure was only 2.12%. The results of multiple logistic regression analysis showed that gender, age, season, and different blood pressure measurement modes were all influencing factors for the detection rate of elevated blood pressure. Conclusion The standardized blood pressure measurement mode in the clinic is suitable for community hypertension screening and pressure measurement, with higher data quality than the conventional pressure measurement mode.

Neuropathic pain is frequently comorbidity with cognitive deficits. Neuralized1 (Neurl1)-mediated ubiquitination of CPEB3 in the hippocampus is critical in learning and memory. However, the role of Neurl1 in the cognitive impairment in neuropathic pain remains elusive. Herein, we found that lumbar 5 spinal nerve ligation (SNL) in male rat-induced neuropathic pain was followed by learning and memory deficits and LTP impairment in the hippocampus. The Neurl1 expression in the hippocampal CA1 was decreased after SNL. And this decrease paralleled the reduction of ubiquitinated-CPEB3 level and reduced production of GluA1 and GluA2. Overexpression of Neurl1 in the CA1 rescued cognitive deficits and LTP impairment, and reversed the reduction of ubiquitinated-CPEB3 level and the decrease of GluA1 and GluA2 production following SNL. Specific knockdown of Neurl1 or CPEB3 in bilateral hippocampal CA1 in naïve rats resulted in cognitive deficits and impairment of synaptic plasticity. The rescued cognitive function and synaptic plasticity by the treatment of overexpression of Neurl1 before SNL were counteracted by the knockdown of CPEB3 in the CA1. Collectively, the above results suggest that the downregulation of Neurl1 through reducing CPEB3 ubiquitination and, in turn, repressing GluA1 and GluA2 production and mediating synaptic plasticity impairment in hippocampal CA1 leads to the genesis of cognitive deficits in neuropathic pain.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

ObjectiveTo analyze the distribution characteristics of traditional Chinese medicine （TCM） syndrome elements in different risk populations of heart failure complicated with type 2 diabetes. MethodsClinical data of 675 type 2 diabetes patients were retrospectively collected. Lasso-multivariate Logistic regression was used to construct a clinical prediction nomogram model. Based on this， 441 non-heart failure patients were divided into a low-risk group （325 cases） and a high-risk group （116 cases） according to the median risk score of heart failure complicated with type 2 diabetes. TCM diagnostic information （four diagnostic methods） was collected for both groups， and factor analysis was applied to summarize the distribution of TCM syndrome elements in different risk populations. ResultsLasso-multivariate Logistic regression analysis identified age， disease duration， coronary heart disease， old myocardial infarction， arrhythmia， absolute neutrophil count， activated partial thromboplastin time， and α-hydroxybutyrate dehydrogenase as independent risk factors for heart failure complicated with type 2 diabetes. These were used as final predictive factors to construct the nomogram model. Model validation results showed that the area under the curve （AUC） of the receiver operating characteristic （ROC） curve for the modeling group and validation group were 0.934 and 0.935， respectively. The Hosmer-Lemeshow test （modeling group P = 0.996， validation group P = 0.121） indicated good model discrimination. Decision curve analysis showed that the curves for All and None crossed in the upper right corner， indicating high clinical utility. The low-risk and high-risk groups each obtained 14 common factors. Preliminary analysis revealed that the main disease elements in the low-risk group were qi deficiency （175 cases， 53.85%）， dampness （118 cases， 36.31%）， and heat （118 cases， 36.31%）， with the primary locations in the spleen （125 cases， 38.46%） and lungs （99 cases， 30.46%）. In the high-risk group， the main disease elements were yang deficiency （73 cases， 62.93%）， blood stasis （68 cases， 58.62%）， and heat （49 cases， 42.24%）， with the primary locations in the kidney （84 cases， 72.41%） and heart （70 cases， 60.34%）. ConclusionThe overall disease characteristics in different risk populations of type 2 diabetes patients with heart failure are a combination of deficiency and excess， with deficiency being predominant. Deficiency and heat are present throughout. The low-risk population mainly shows qi deficiency with dampness and heat， related to the spleen and lungs. The high-risk population shows yang deficiency with blood stasis and heat， related to the kidneys and heart.

Objective Currently, there is no commercially available quantitative detection kit for the main Felis domestic allergen (Fel d 1) in China. To establish a rapid detection method for Fel d 1, this study aims to prepare monoclonal antibodies against Fel d 1 protein. Methods The codon preference of Escherichia coli was utilized to optimize and synthesize the Fel d 1 gene. The prokaryotic expression plasmid pET-28a-Fel d 1 was constructed and used to express and purify the recombinant Fel d 1 protein. Subsequently, the recombinant protein was immunized into BALB/c mice and monoclonal antibodies (mAbs) were prepared by the hybridoma technique. An indirect ELISA was established using the recombinant Fel d 1 as the coating antigen, and hybridoma cell lines were screened for positive clones. The specificity and antigenic epitopes of the mAbs were confirmed by Western blot analysis. Finally, the selected hybridoma cells were injected into the peritoneal cavities of BALB/c mice for large-scale monoclonal antibody production. Results The recombinant plasmid pET-28a-Fel d 1 was successfully constructed, and soluble Fel d 1 protein was obtained after optimizing the expression conditions. Western blot and antibody titer assays confirmed the successful isolation of two hybridoma cell lines, 7D11 and 5H4, which stably secreted mAbs specific to Fel d 1. Antibody characterization revealed that the 5H4 mAb was of the IgG2a subtype and could recognize the amino acid region 105-163 of Fel d 1, while the 7D11 mAb was the IgG1 subtype and could recognize the amino acid region 1-59. Conclusion The high-purity recombinant Fel d 1 protein produced in this study provides a promising alternative for clinical immunotherapy of cat allergies. Furthermore, the monoclonal antibody prepared in this experiment lays a material foundation for the in-depth study of the biological function of Fel d 1 and the development of ELISA detection.

Objective:To explore the dilemmas in the discharge preparation process of postoperative breast cancer patients within the framework of Meleis' Transition Theory, and to provide evidence for the development of nursing interventions to improve discharge readiness.Methods:This was a qualitative study. Using purposive sampling, postoperative breast cancer patients hospitalized in the Department of Breast Surgery of Nanjing Drum Tower Hospital, Affiliated Hospital of Medical School, Nanjing University between September and October 2024 were selected for the study. Semi-structured, in-depth interviews were conducted. Data were analyzed and themes extracted using Colaizzi's seven-step analysis method.Results:A total of four themes were extracted: personal status-patients experienced complex emotions at discharge; disease knowledge preparation-patients had insufficient mastery of relevant knowledge after discharge; coping ability-patients lacked confidence in home self-care after returning home; social support-patients desired support from peers and medical staff.Conclusions:Postoperative breast cancer patients face multiple dilemmas during discharge preparation. Medical staff are advised to pay attention to the psychological status of discharged patients and develop individualized emotional coping strategies; provide professional information and meet patients' fertility and sexual health knowledge needs; optimize health education models to enhance patients' home coping ability; and strengthen the integration of mobile health with nursing practice to build a multidimensional support system.

Objective:To compare the efficacy and safety differences between direct mechanical thrombectomy (abbreviated as direct thrombectomy) and bridging therapy in patients with acute anterior circulation large vessel occlusion and atrial fibrillation.Methods:A retrospective collection of data was conducted for hospitalized patients who underwent mechanical thrombectomy due to acute anterior circulation large vessel occlusion with atrial fibrillation at the First Affiliated Hospital of Soochow University and Suzhou Kowloon Hospital, Shanghai Jiao Tong University School of Medicine from January 1, 2018 to December 31, 2022. Patients were divided into direct thrombectomy and bridging therapy groups based on whether intravenous thrombolysis was used, and the clinical outcomes and safety indicators of the two groups were compared. The primary clinical outcomes included the modified Rankin Scale (mRS) score at 90 days and the proportion of patients with neurological independence at 90 days (the proportion of patients with mRS scores of 0-2). Safety indicators included 90-day mortality rate, intracranial hemorrhage rate, symptomatic intracranial hemorrhage [deterioration of neurological function and an increase of ≥4 points in the National Institutes of Health Stroke Scale (NIHSS) score] rate, and pneumonia incidence. Using the 90-day prognosis as a dependent variable, a binary Logistic regression analysis was conducted to investigate the factors influencing poor prognosis in patients at 90 days.Results:Among the 534 screened patients, 125 were included in the study, with 74 in the direct thrombectomy group and 51 in the bridging therapy group. The difference in the mRS scores at 90 days between the direct thrombectomy group and the bridging therapy group was not statistically significant [2 (0, 3) vs 3 (1, 3), Z=-1.444, P=0.149]. The difference in the proportion of patients with independent neurological function at 90 days [66.2% (49/74) vs 47.1% (24/51), χ2=4.561, P=0.033] was statistically significant between the 2 groups. The 90-day mortality rate [5.4% (4/74) vs 9.8% (5/51), χ 2=0.936, P=0.483], the intracranial hemorrhage rate [17.6% (13/74) vs 29.4% (15/51), χ 2=2.437, P=0.119], the symptomatic intracranial hemorrhage rate [12.2% (9/74) vs 23.5% (12/51), χ 2=2.791, P=0.095], and the pneumonia incidence [59.5% (44/74) vs 56.9% (29/51), χ 2=0.084, P=0.772] between the 2 groups showed no statistically significant differences (all P>0.05). The time from admission to puncture was 97 (74, 122) min and 150 (127, 168) min for the direct thrombectomy and bridging therapy groups, respectively, with a statistically significant difference ( Z=-5.846, P<0.001). Binary Logistic regression analysis showed that venous thrombolysis (adjusted OR=3.004, 95% CI 1.057-8.539, P=0.039), NIHSS score at onset (adjusted OR=1.096, 95% CI 1.009-1.191, P=0.030), and pneumonia (adjusted OR=12.814, 95% CI 3.775-43.499, P<0.001) were associated with poor prognosis at 90 days. Conclusion:For patients with acute anterior circulation large vessel occlusion and atrial fibrillation, direct thrombectomy can increase the proportion of neurological independence at 90 days compared to bridging therapy, with no statistically significant differences in safety indicators, which may be related to the shorter time from admission to puncture in the direct thrombectomy group.

Objective:To investigate the risk factors for heterotopic ossification (HO) after shoulder arthroplasty for patients with proximal humerus fracture.Methods:A retrospective study was conducted to analyze the clinical data of 95 patients with proximal humeral fracture who had undergone shoulder arthroplasty at Department of Sports Medicine, Beijing Jishuitan Hospital between January 2002 and December 2020. The cohort included 69 females and 26 males with an age of (66.8±11.8) years. By the Neer classification, 39 patients had three-part fractures, and 56 ones four-part fractures. According to the postoperative occurrence of HO, the patients were divided into an HO group and an HO-free group. Univariate analysis was performed for factors such as age, gender, time from injury to surgery, injury mechanism, involvement of the dominant side, surgical approach, and the Shoulder and Elbow Surgeons (ASES) score, visual analog scale (VAS) for pain, and shoulder range of motion at the final follow-up in the 2 groups. After positive indicators ( P<0.05) were screened through univariate analysis, they were included in a multivariate logistic regression model to analyze the risk factors for HO following shoulder arthroplasty. Results:All patients were followed up for (83.7±39.8) months. At the final follow-up, the incidence of HO was 34.7% (33/95). There were no statistically significant differences between the 2 groups in gender, time from injury to surgery, injury mechanism, surgical approach, or ASES score, VAS pain score, or shoulder range of motion at the final follow-up ( P>0.05). The univariate analysis showed that the age was significantly younger ( P=0.009), and the proportion of the dominant side involvement significantly lower ( P=0.016) in the HO patients. Multivariate logistic regression analysis showed that a younger age ( OR=0.947, 95% CI: 0.910 to 0.985, P=0.007) was an independent risk factor for HO in patients with proximal humerus fracture after shoulder arthroplasty. Conclusion:A younger age is the risk factor for HO after shoulder arthroplasty for patients with proximal humerus fracture.
