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    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 establish HPLC fingerprint of Guzhecuoshang capsules, and its quality was evaluated by chemical pattern recognition. METHODS The HPLC-DAD method was used to establish the fingerprint of Guzhecuoshang capsules. The main chromatographic peaks were confirmed and assigned, and finally analyzed them through cluster analysis(CA), principal component analysis(PCA) and orthogonal partial least squares discriminant analysis(OPLS-DA) models. RESULTS The similarity of 75 batches of Guzhecuoshang capsules was covered from 0.685 to 0.986. A total of 26 common peaks were marked, and 6 components were identified respectively: hydroxysafflor yellow A(peak 1), ferulic acid(peak 6), aloeemodin(peak 15), emodin(peak 19), chrysophanol(peak 24) and physcion(peak 26). CA could be divided into five categories. The PCA and OPLS-DA screened out 13 main differentially contributing components, and it was indicated by the attribution of components that controlling the quality of safflower play an important role in ensuring the stability of the quality of Guzhecuoshang capsules. CONCLUSION The established HPLC fingerprint is relatively stable and reliable, which can basically reflect the characteristics of the chemical components in the compound, and can also provide a reference for the quality control and standard improvement of Guzhecuoshang capsules.

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.

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.

Burning mouth syndrome (BMS) is a chronic oral and facial pain disorder characterized by burning pain in the oral mucosa, with multiple pathogenic factors including psychosocial, neuropathological, endocrine, and immune factors. There is still a lack of effective treatment options that have been demonstrated to work. With the development of research on the pathogenesis and treatment of BMS, multidisciplinary comprehensive treatment has gradually been introduced and become a new trend of diagnosis and treatment. Before multidisciplinary treatment, it is necessary to go through a full and comprehensive diagnosis and analysis, select the best comprehensive treatment plan, take the diagnosis and treatment of stomatology as the basis and premise, and apply other multidisciplinary combined treatment, including the treatment of concurrent diseases, psychological interventions, correction of bad habits, etc. A combination of laser therapy and psychological intervention is a more effective treatment method among the current treatment methods, with high comfort and good acceptance by patients. If necessary, mecobalamin tablets, clonazepam α-lipoic acid and other drugs can be used to nourish nerves and provide symptomatic treatment. The comprehensive multidisciplinary treatment of BMS is expected to become a new trend and provide a new strategy for improving the therapeutic effect.

Objective To investigate the incidence of multiple disease coexistence in emergency department patients over 65 years old and its impact on the risk of death in hospital, so as to provide theoretical basis for reducing the risk of death in emergency department patients over 65 years old. Methods From January 2019 to January 2020, elderly patients over 65 years old who received emergency treatment in our hospital were selected as subjects to analyze the coexistence of multiple diseases. The information of current disease, blood pressure, blood glucose level and other potential influencing factors, as well as the incidence of hospitalization after emergency treatment were collected, and the factors influencing the risk of death in hospital were analyzed and discussed. Results During the study period, there were 1 195 patients over 65 years old, including 469 patients with multi-disease coexistence (excluding malignant tumors), with an incidence rate of 39.25%. Among the elderly patients in the emergency department, the top four diseases with multiple coexisting diseases are as follows: ischemic stroke (43.92%), acute myocardial infarction (24.95%), hemorrhagic stroke (16.84%), and falls (11.30%). In addition, ^“ischemic stroke + hypertension + diabetes + coronary heart disease^” accounted for the highest proportion (42.22%) in the combination of multi-disease coexisting diseases, followed by "myocardial infarction + ischemic stroke + hypertension + Diabetes + coronary heart disease^” (21.11%), and the third in the composition ratio was ^“fall + ischemic stroke + hypertension + diabetes + coronary heart disease^” (0.66%). Among the 469 patients with multi-disease coexistence, a total of 68 died during hospitalization after emergency department; 469 patients were divided into two groups: the dead and the survivors, and the potential factors affecting the risk of death were analyzed. The multivariate regression analysis showed that male (OR=1.485 , P<0.001), age over 80 years (OR=3.090, P<0.05), more than four types of comorbidities (OR=4.407, P<0.001), BMI level showed weight loss (OR=4.366, P<0.001) and Comorbidities included hypertension (OR=3.564, P<0.001) as a potential risk factor, which would increase the risk of death; while normal blood pressure (OR=0.581, P<0.001) might potentially reduce the risk of death. Conclusion Special attention should be paid to the elderly patients over 65 years old who are male, over 80 years old, thin and with many types of comorbidities (more than four types), especially those with hypertension at the same time, in order to reduce hospitalization after emergency department risk of death during the period.

Objective     To evaluate the early clinical outcomes of the Renatus® balloon-expandable valve in the treatment of severe aortic stenosis. Methods    From November 2021 to April 2022, a total of 38 patients who received Renatus® balloon-expandable valve for severe aortic stenosis in Guangdong Provincial People&#39;s Hospital were included. There were 22 males and 16 females, with an average age of 73.7±5.3 years. Mean aortic gradient and peak aortic jet velocity at baseline, post-procedure, and follow-up were compared. Clinical outcomes including all-cause mortality, perivalvular leakage, serious adverse cardiovascular events and the occurrence of permanent pacemaker implantation were assessed. Results    All patients completed the procedure successfully without conversion to thoracotomy or perioperative death. The post-implant mean aortic pressure gradient was decreased from 41.5 (27.8, 58.8) mm Hg to 6.0 (3.0, 8.0) mm Hg, and the peak aortic jet velocity was also decreased from 4.1±0.9 m/s to 1.7±0.4 m/s (P<0.001). Pacemakers were required in 2 (5.3%) patients. The median follow-up time was 27.5 (23.0, 87.5) d, with a follow-up rate of 100.0%. The mean aortic gradient was 8.0 (7.0, 10.8) mm Hg and peak aortic jet velocity was 2.0±0.3 m/s, showing significant improvement compared with those in the preoperative period (P<0.001). No severe aortic regurgitation or paravalvular leak was observed. There was no serious cardiovascular adverse event or reoperative event during the study period. Conclusion    Transcatheter aortic valve replacement with the domestic Renatus® balloon-expandable valve system is a safe and effective procedure for selected patients with severe aortic stenosis who are at high risk or not candidates for surgical aortic valve replacement.

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.
