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.

Objective To investigate the current status of sleep disorders in patients with Alzheimer’s disease (AD) and its relationship with physical activity, and analyze the intervention effect of light therapy. Methods A total of 345 patients with AD admitted to the First Affiliated Hospital of Air Force Medical University from June 2020 to June 2025 were included. The Pittsburgh Sleep Quality Index (PSQI) was used to evaluate the sleep disorders, and the Physical Activity Scale for the Elderly (PASE) was applied to evaluate the physical activity. Pearson correlation analysis model was adopted to analyze the correlation between PSQI and PASE in patients with AD. 345 patients with AD were treated with light therapy intervention for 4 weeks. The changes of PSQI and PASE scores were compared before and after intervention. Results Among the 345 patients with AD, 251 cases had sleep disorders, accounting for 72.75% (251/345), and the PSQI score was (9.87±2.95) points. The scores of leisure activity, housework and occupation-related activity of PASE were (25.81±6.12) points, (78.15±12.93) points, and (45.31±8.74) points, respectively. Pearson correlation analysis model revealed that the leisure activity score of PASE was negatively correlated with the PSQI score (P<0.05), and the scores of housework and occupation-related activity were not significantly correlated with the PSQI score (P>0.05). After 4 weeks of light therapy intervention, the score of leisure activity of patients was increased significantly (P<0.05), while the scores of housework and occupation-related activity did not change significantly (P>0.05), and the PSQI scores were decreased significantly (P<0.05). Conclusion There is a correlation between sleep disorders and leisure time and physical activity in patients with Alzheimer&#39;s disease. The implementation of light therapy intervention can effectively improve sleep disorders in AD patients.

Objective To investigate the relationship between Helicobacter pylori (Hp) infection and disease severity and pathological type of intestinal polyps in inpatients. Methods The data of 303 inpatients with intestinal polyps in the hospital from August 2022 to February 2025 were collected and analyzed. The clinical characteristics of patients were analyzed, and the influencing factors of pathological types of polyps were explored. Results Among the 303 inpatients with intestinal polyps, there were 135 Hp positive cases and 168 Hp negative cases. The number of polyps, maximum polyp diameter, number of ileocecus/ascending colon/transverse colon polyps, number of descending colon/sigmoid colon/rectal polyps and adenomatous polyps in the Hp-positive group were higher than those in the Hp-negative group (P<0.05). Multivariate logistic regression analysis indicated that age [OR (95%CI)=1.03 (1.01-1.05)] and positive Hp[OR (95%CI)=2.61 (1.62-4.20)] were independent risk factors of occurrence of adenomatous polyps (P<0.05). ROC curve results revealed that the AUCs of age, positive HP and combination in the diagnosis of adenomatous polyps were 0.574, 0.608 and 0.646, and the 95%CI values were 0.509-0.638, 0.545-0.672 and 0.584-0.708 respectively. The efficiency of combination of the two indexes was higher than that of single diagnosis. Conclusion Hp infection is associated with disease severity in inpatients with intestinal polyps, and it may be involved in the occurrence and development of adenomatous polyps.

Objective This study aimed to comprehensively survey the tick distribution in the natural scenic belts of various counties and districts in Huai&#39;an City, Jiangsu Province, and to provide guidance on tick control measures. Methods From 2023 to 2024, questing ticks in 29 natural scenic belts spanning seven counties and districts of Huai&#39;an City were collected using hand-scratching method. Further, parasitic ticks in the surrounding areas were collected using the animal search method. Collected ticks were subsequently identified to the species level in the laboratory. Results In total, 288 questing ticks were collected, all belonging to the genus Haemaphysalis of family Ixodidae. Hae. longicornis was the dominant species, accounting for 98.61%, followed by Hae. flava(1.04%)and Hae. phasiana(0.35%). The average tick density index in Lotus Lake Scenic Area(Jinhu County), All-People Fitness Theme Park(Lianshui County), Peach Blossom Valley(Qingjiangpu District), Huai&#39;an Forest Park(Huai&#39;an District), Qizu of Gaozhuang Village(Hongze District), Ancient Yellow River Sports Park(Huaiyin District), Putao Trench and(Xuyi County)was 0.022, 0.025, 0.01, 0.10,0.22,0.28, and 0.79 ticks/flag·100 m, respectively. In total,114 parasitic ticks were collected at the monitoring sites, with an average tick infestation rate of 69.25% in sheep and 100% in dogs at Tianquanhu Town in Xuyi County; all of these were Hae. longicornis. All parasitic ticks were from Xuyi County, and no parasitic ticks were found at the monitoring sites in Huai&#39;an District, Hongze District, and Lianshui County. Conclusions Overall, with the advancement of eco-tourism resorts and urban greening construction in Huai&#39;an City, the presence of ticks was confirmed by this study in previously unsurveyed areas. As the frequency of human-animal interactions increases in these areas, the potential risk of tick-borne diseases also rises. Furthermore, this study provides important clues for subsequent investigations into local tick-borne pathogens.

Objective    To predict the probability of lymph node metastasis after thoracoscopic surgery in patients with lung adenocarcinoma based on nomogram. Methods    We analyzed the clinical data of the patients with lung adenocarcinoma treated in the department of thoracic surgery of our hospital from June 2018 to May 2021. The patients were randomly divided into a training group and a validation group. The variables that may affect the lymph node metastasis of lung adenocarcinoma were screened out by univariate logistic regression, and then the clinical prediction model was constructed by multivariate logistic regression. The nomogram was used to show the model visually, the receiver operating characteristic (ROC) curve, calibration curve and clinical decision curve to evaluate the calibration degree and practicability of the model. Results    Finally 249 patients were collected, including 117 males aged 53.15±13.95 years and 132 females aged 47.36±13.10 years. There were 180 patients in the training group, and 69 patients in the validation group. There was a significant correlation between the 6 clinicopathological characteristics and lymph node metastasis of lung adenocarcinoma in the univariate logistic regression. The area under the ROC curve in the training group was 0.863, suggesting the ability to distinguish lymph node metastasis, which was confirmed in the validation group (area under the ROC curve was 0.847). The nomogram and clinical decision curve also performed well in the follow-up analysis, which proved its potential clinical value. Conclusion    This study provides a nomogram combined with clinicopathological characteristics, which can be used to predict the risk of lymph node metastasis in patients with lung adenocarcinoma with a diameter≤3 cm.

Objective: To evaluate the effect of Tai Chi and Qigong on patients with lumbar disc herniation (LDH). Methods: Relevant data were retrieved from nine English and Chinese databases, including Cochrane Library, PubMed, and Wanfang Data, etc. from inception to June 2024. All published randomized controlled trials assessing the effect of Tai Chi and Qigong on visual analog scale (VAS), Japanese Orthopedic Association (JOA) score, and other health indicators in participants with LDH compared to usual medical care or other treatments were included. Grey literature, trials involving the pushing of hands (Tui Shou) or Tai Chi with weapons, and trials with co-interventions (Tai Chi/Qigong plus another treatment) were excluded. Methodological quality was analyzed using the Cochrane risk of bias tool, and evidence quality was assessed using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) tool. Results: Fourteen trials (954 patients) were included in this study. Tai Chi and Qigong were associated with lower VAS pain scores (standardized mean difference −0.55, 95% confidence interval [CI] −0.95 to −0.15, P = .01), higher JOA scores (mean difference [MD] 4.40, 95% CI 2.62 to 6.18, P < .001) and straight leg raise test results (MD 9.40°, 95% CI 7.64 to 11.15, P < .001) in patients with LDH. Furthermore, compared with usual care, Tai Chi and Qigong showed enhanced effects on pain and JOA scores. When compared to other exercises or massage, the effect on pain scores was similar but that on JOA scores was significant. Conclusions Tai Chi and Qigong may have favorable effects on VAS pain and JOA scores compared with usual care, and on JOA scores compared with other exercises or massage in patients with LDH. Given the overall poor quality of the evidence, the results of current study should be interpreted cautiously.

Abstract OBJECTIVE Neuroblastoma(NB) is a prevailing pediatric extracranial solid tumor that accounts for 10%-15% of all childhood cancer-related fatalities. Despite significant strides made in NB therapy through multimodal approaches, the survival rate of high-risk NB patients remains at approximately 50%. Consequently, there is an urgent need to identify novel molecular targets for NB treatment. Recent studies have shown that MYCN oncogene amplification is present in about 25% of NB cases and is a crucial determinant of poor prognosis for high-risk NB patients. Since MYC family proteins, including MYCN, are inherently disordered proteins, MYCN lacks a defined ligand binding site along with a large protein-protein interaction surface. Current treatment approaches for MYCN-amplified NB patients do not include direct targeting of MYCN itself, since the absence of a “drugable” pocket renders it challenging. Notably, no direct MYC-targeting drugs are currently available. There is an existing association between Aurora A kinase(AURKA) and MYCN, whereby they form a complex to fortify MYCN stability. However, MYCN is inherently unstable, with a half-life of only 30 min, but AURKA intervenes by facilitating its stability through a direct protein-protein interaction, hence protecting it from proteasomal degradation. This interaction potentially augments tumor cell proliferation and invasiveness. Notably, AURKA has been verified as a transcriptional target of MYCN. The present study endeavors to employ computer-aided drug design technology to probe AURKA inhibitors discerned from a natural product library of traditional Chinese medicine(TCM), thereby identifying a novel drug for treating NB. METHODS Collected from the YaTCM database, a total of 47 696 natural compounds from TCM were subjected to preprocessing including protonation, deionization, hydrogenation, stereoisomerism, conformation generation, and energy minimization. Of these, 58 048 compounds were initially screened as potential ligands for the library. Utilizing “Lipinski Ro5” and “Verber Ro3” guidelines, 22 227 hit compounds were selected from the library that met the screening criteria. Initially, crystal structures of AURKA and its inhibitor AA35 were downloaded from the RCSB PDB database. The spatial coordinates of AA35 were set as the center of the binding pocket for AURKA, and a 10 Å * 10 Å * 10 Å space around the pocket was designated as the active space. A comprehensive drug screening platform integrating lead-likeness filtering, pharmacokinetic prediction, molecular docking, flexible docking, and molecular dynamics(MD) simulations were established to excavate potential aurora kinase A inhibitors from the TCM compound library, which were further validated by MD simulations. RESULTS A grand total of 6 220 Chinese herbal remedies had been meticulously curated within the YaTCM database. Out of these, an impressive 47 696 Chinese herbal monomers had undergone a rigorous series of flexible docking tests, resulting in the selection of the top ten molecules with the most favorable docking scores. The aforementioned molecules underwent AMDE parameter and toxicity predictions. It was discovered that with the exception of a few compounds such as Tryptophane, 3&#39;-Methoxydaidzein, and Burttinol D(which might elicit liver toxicity), 3&#39;-Methoxydaidzein and Pratensein(which might elicit kidney toxicity), and 3-Deoxysappanone B(which had moderate oral toxicity), as well as Tryptophane(with an oral bioavailability of less than 50%), five compounds including Compound X, (+)-Sesamin dicatechol, Tuberosin, Abrine, and Maackiain, displayed favorable pharmacokinetic parameters and low toxicity predictions. Moreover, all of these compounds exhibited a high binding affinity with the inhibitor active pocket of AURKA. In this study, Compound X, despite its cumbersome name, was referred to as “Compound X”. Upon focusing on Compound X as the subject of investigation, it was discovered that its phenolic framework could readily interact with the hydrophobic cavity constituted of hydrophobic amino acids, namely TYR199, VAL182, LEU178, LEU208, and VAL206. Notably, Compound X could partake in Pi-Pi interactions with TYR199 and create hydrogen bonds with HIS201, GLU175, and LYS166. Computational studies via MD simulations confirmed that Compound X could form a stable receptor-ligand complex with the receptor. Impressively, the inclusion of Compound X significantly reduced the stability of the AURKA-MYCN complex. CONCLUSION This study concludes that Compound X can be used as an AURKA inhibitor for the treatment of NB, which is a novel finding based on the combination of various virtual screening techniques from the natural product database of TCM.

Objective     To investigate the risk factors for postoperative complications Clavien-Dindo classification≥grade Ⅱ after lung cancer surgery. Methods     The patients who underwent lung cancer surgery in a multicenter observational study from November 2017 to January 2020 were included. The Clavien-Dindo classification of postoperative complications was analyzed. Logistic regression was used to identify the risk factors for complications≥ gradeⅡ. Results     A total of 388 patients were enrolled, including 203 males and 185 females with a mean age of 56.14±10.36 years. The incidence of postoperative complications was 25.52% (99/388) after lung cancer surgery and the incidence of complications≥gradeⅡ was 20.10% (78/388). The five most common postoperative complications were pneumonia (6.96%), prolonged pulmonary air leak (>7 days, 5.67%), incision dehiscence (4.64%), arrhythmia (3.87%), and postoperative pleural effusion (3.35%). Multivariate analysis showed that open surgery [reference: uniportal thoracoscopic surgery, OR=2.18, 95%CI (1.01, 4.70), P=0.047], extended resection [reference: sublobar resection, OR=2.86, 95%CI (1.11, 7.19), P=0.030; reference: lobectomy, OR=2.20, 95%CI (1.10, 4.40), P=0.026] and operative time≥3 h [OR=2.07, 95%CI (1.12, 3.85), P=0.021] were independent risk factors for postoperative complications≥gradeⅡ after lung cancer surgery. Conclusion     Surgical approach, extent of resection and operative time are independent influencing factors for postoperative complications≥gradeⅡ after lung cancer surgery.

Telephone follow-up is one of the important ways to follow up patients. High-quality follow-up can benefit both doctors and patients. However, clinical research-related follow-up is often faced with problems such as time-consuming, laborious and poor patient compliance. The authors belong to a team that has been committed to the study of patient-reported outcomes for a long time. The team has carried out long-term follow-up of symptoms, daily function and postoperative complications of more than 1 000 patients after lung cancer surgery, and accumulated certain experience. In this paper, the experience of telephone follow-up was summarized and discussed with relevant literatures from the aspects of clarifying the purpose of clinical research follow-up, understanding the needs of patients in follow-up, and using follow-up skills.

Objective : To investigate the role and mechanism of bone formation caused by the ratio of advanced platelet-rich fibrin (A-PRF) and β-tricalcium phosphate (β-TCP) in rabbit femur defect model, which provides a new idea for clinical treatment of bone defect. Methods : Twenty-four New Zealand white rabbits were divided into model group, 1∶1 complex group (A-PRF∶β-TCP=1∶1), 2∶1 complex group (A-PRF∶β- TCP=2∶1) and 4∶1 complex group (A-PRF∶β- TCP=4∶1）, with 6 rabbits in each group. Femoral defect models were constructed in each group. In the composite group, the bone defect was filled with composite material, while in the model group, no material was filled. After 8 weeks, the animals were euthanized and specimens were collected. Bone mineral density (BMD), bone volume fraction (BV/TV), trabecular thickness (Tb.Th), trabecular separation (Tb.SP) and trabecular number (Tb.N) in femoral defect tissue were measured by micro-CT and photographed. Hematoxylin - eosin staining was used to detect the pathological changes of new bone tissue. The morphological changes of the new bone tissue were observed by scanning electron microscopy. Determination of phospho-mitogen activated protein kinase p38 (p-p38MAPK), CCAAT/enhancer binding protein homologous protein (CHOP) and phospho-cysteine aspartic protease-3 (p-Caspase3) in newborn femur by ELISA. The mRNA expressions of osteoprotegerin (OPG), bone morphogenetic protein-2 (BMP-2), receptor activator of nuclear factor kappa-B ligand (RANKL) and p38MAPK were detected by real-time quantitative PCR. The expression of OPG, BMP-2, RANKL, p-p38MAPK and p-Caspase3 protein in the new bone tissue was observed by immunohistochemistry. Results : In the model group, bone formation in the femoral defect area was slow and osteogenic quality was poor. Compared with the model group, the bone formation and neocapillaries of femoral defect area in the complex group was good, BMD, BV.TV, Tb.Th, Tb.N were increased, and Tb.Sp were decreased, the expressions of p-p38MAPK, CHOP and p-Caspase3 were decreased, and the mRNA and protein expressions of OPG and BMP-2 were increased. The mRNA expression of RANKL and p38MAPK was decreased. Apoptosis in new bone tissue of each group showed the lowest apoptosis rate in samples of the 2∶1 complex group (P<0.05); A-PRF: β-TCP=2∶1 ratio has the best osteogenic effect. Conclusion The complex composed of A-PRF and β-TCP can promote the expression of OPG, inhibit the expression of RANKL and phosphorylation of p38MAPK, reduce the apoptosis of new bone tissue cells, and promote osteogenic differentiation.
