Objective To explore the associations of dietary patterns with bone mineral density(BMD)and osteoporosis(OP)in patients with knee osteoarthritis(KOA)in south China,identify the dietary patterns that could reduce the risk of OP,and provide a reference for prevention of OP.Methods Data from 600 KOA patients who were enrolled in the Pearl River Osteoarthritis Cohort(PROC)between April 2020 and April 2024 were extracted,including general characteristics,dietary questionnaire and BMD test.Factor analysis was employed to identify dietary patterns.Scores of dietary pattern were treated as continuous or categorical variables(quartile-based groups).Multivariable linear regression was used to assess associations between scores of dietary pattern and BMD,while the relationships with OP were analysed by binary logistic regression.Results The prevalence of OP in KOA patients was 19.8%.Factor analysis extracted eight dietary patterns:seafood-nuts,livestock-poultry meats,coarse grains-fruits,wheat-eggs,fish-dairy-vegetables,legumes-fruits,rice-wheat flour,and soy-dairy.After adjusting for confounders,it was found that the pattern of coarse grains-fruits was positively correlated with the BMD of left femoral neck and lumbar spine(P<0.01)and the fish-dairy-vegetables pattern was positively correlated with the BMD of lumbar spine(P<0.01).When pattern scores were discretized into quartiles,the legumes-fruits pattern(Q3 vs.Q1)was found in association with a 68.2%reduction in the risk of OP(P<0.05).Conclusion This study has identified that the pattern of legumes-fruits may lower a risk of OP,while the patterns of coarse grains-fruits and fish-dairy-vegetables correlate with higher BMD.The diet patterns are potentially beneficial to prevention of OP.For bone health,a balanced diet rich in legumes,fruits,vegetables,coarse grains,fish,nuts and dairy is recommended.

Objective To explore the intrinsic relationship between imaging features of the bony structure in varus-type knee osteoarthritis(KOA).Methods A total of 99 patients diagnosed with varus-type KOA were retrospectively selected.All patients underwent standard weight-bearing full-length X-ray radiographs of both lower extremities and 3D CT scans of the knee joints.The images were observed and analyzed at the picture archiving and communication system(PACS)workstation.The hip-knee-ankle(HKA)angle and tibial medial plateau settlement value were measured,the size of osteophyte was measured and graded,and the distribution of subchondral pseudocysts was counted.Correlation analysis was performed on the above imaging indicators,and scatter plots were drawn for linear correlations.Results There was a correlation between the HKA angle and the tibial medial plateau settlement value,with a correlation coefficient(r)of-0.548.The osteophyte grades in each subregion were correlated with the HKA angle,with r of-0.324,-0.307,-0.534,-0.581,-0.468,-0.245,-0.265,-0.244,-0.706,-0.741,-0.726,-0.326,-0.712,-0.218,respectively.There was correlation between the osteophyte grades in the medial patella,medial femoral subregion,and medial tibial subregion and the tibial medial settlement value,with r of 0.227,0.263,0.295,0.242,0.297,0.361,and 0.407,respectively.No correlation was found between the osteophyte grades in other subregions and the tibial medial settlement value.There was an overall correlation between osteophyte grades and subchondral pseudocysts,with a r of 0.245,but with regional differences.No correlation was found between the medial femoral osteophyte grades and subchondral pseudocysts,while correlations were observed in other zones,with r of 0.213,0.230,0.200,and 0.147,respectively.Conclusion KOA is a disease of the entire knee joint.The imaging features of its bony structure,including the HKA angle,tibial medial plateau settlement value,osteophyte grades,and subchondral pseudocysts,have both intrinsic relationship and regional differences,which are influenced by anatomical structures.

Background/Aims: Endoscopic radiofrequency ablation (ERFA) is a treatment option for superficial esophageal squamous cell neoplasia (ESCN), with a relatively low risk of stenosis; however, the long-term outcomes remain unclear. We aimed to compare the long-term outcomes of patients with widespread superficial ESCN who underwent endoscopic submucosal dissection (ESD) or ERFA. Methods: We retrospectively analyzed the clinical data of patients with superficial ESCN who underwent ESD or ERFA between January 2015 and December 2021. The primary outcome measure was recurrence-free survival. Results: Ninety-two and 33 patients with superficial ESCN underwent ESD and ERFA, respectively. The en bloc, R0, and curative resection rates for ESD were 100.0%, 90.2%, and 76.1%, respectively. At 12 months, the complete response rate was comparable between the two groups (94.6% vs 90.9%, p=0.748). During a median follow-up of 66 months, recurrence-free survival was significantly longer in the ESD group than in the ERFA group (p=0.004), while no significant differences in overall survival (p=0.845) and disease-specific survival (p=0.494) were observed.Preoperative diagnosis of intramucosal cancer (adjusted hazard ratio, 5.55; vs high-grade intraepithelial neoplasia) was an independent predictor of recurrence. Significantly fewer patients in the ERFA group experienced stenosis compare to ESD group (15.2% vs 38.0%, p=0.016). Conclusions The risk of recurrence was higher for ERFA than ESD for ESCN but overall survival was not affected. The risk of esophageal stenosis was significantly lower for patients who underwent ERFA.

Head and neck squamous cell carcinoma (HNSCC) is a tumor characterized by immunosuppressive tumor microenvironment (TME) and poor prognosis. Its complex immune evasion mechanisms are primarily related to T cell dysfunction and the suppression of anti-tumor immune responses. Immunotherapy aims to modulate the patient’s immune system to recognize and eliminate tumor cells, thereby achieving therapeutic goals. Studies have demonstrated that the TME plays a pivotal role in HNSCC pathogenesis, facilitating tumorigenesis, progression, and therapy resistance, ultimately contributing to adverse clinical outcomes. Advances in technology have deepened understanding of the TME, paving the way for novel therapeutic interventions in HNSCC. This review comprehensively summarizes the efficacy and safety of TME-targeted immunotherapies, integrating evidence from published clinical trials, while proposing insights for future research to develop more effective therapeutic strategies.

Obesity, as a chronic recurrent disease, has become a major public health challenge in China. To implement the requirements of the Healthy China Initiative (2019—2030), under domestic guidelines or consensus statements on overweight and obesity, and in alignment with the latest scientific advances globally, the Quality control protocol for adult overweight and obesity screening in health management (examination) institutions (2025 edition) was developed. This protocol was drafted by the Health Management Center of Shanghai Changzheng Hospital and formulated through multiple rounds of deliberation by experts in China’s health examination quality control field. The protocol establishes unified standards for screening facilities, personnel qualifications, and measurement or testing procedures. It defines specific screening items, outlines a standardized screening pathway, and sets requirements for the final medical review, ensuring the scientific validity, effectiveness, and safety of the screening process. The implementation of this protocol will enhance the consistency of weight management practices for adults across health examination institutions and strengthen the quality control of overweight and obesity screening programs.

OBJECTIVE To summarize the implementation experiences of the China Hospital Association’s Clinical Pharmacist Instructor Training Program Reform， and to evaluate the effectiveness of the reform， thus continuously enhancing the quality and standards of clinical pharmacist instructor training. METHODS The study drew on project evaluation methodologies to summarize the main characteristics of the comprehensive system and new model for clinical pharmacist instructor training established through the reform by literature review. The “learning assessment” and “reaction assessment” were conducted by using Kirkpatrick’s four-level model of evaluation in order to evaluate the effectiveness of the clinical pharmacist instructor training reform through statistically processing and analyzing the performance data and teaching evaluation data of the instructor participants. Based on problem and trend analysis， the future development directions were anticipated for the reform of clinical pharmacist instructor training. RESULTS & CONCLUSIONS The latest round of clinical pharmacist instructor training reform initiated by the Chinese Hospital Association had initially established a four-pronged training system encompassing “recruitment， training， assessment， and management”. It had also forged a training 。 model “oriented towards enhancing clinical teaching competency， with practical learning and skill-based assessment conducted on clinical teaching sites as its core”. Following a period of over three years of gradual reform， the new training system and model became increasingly mature. In both 2023 and 2024， the participants achieved relatively high average total scores in their initial completion assessments [with scores of （84.05± 5.83） and （85.82±4.35） points， respectively]. They also reported a strong sense of gain from the training reform [with self- perceived gain scores of （4.80±0.44） and （4.85±0.39） points， respectively]. The operation and implementation effects of the reform were generally satisfactory. In the future， clinical pharmacist instructor training reforms should continue to address the issues remaining from the current phase， while aligning with global trends in pharmacy education and industry development. Additionally， sustained exploration and practice will be carried out around the core objective of “enhancing clinical teaching competence”.

Objective To analyze the trend of global cellulitis disease burden from 1990 to 2019, and to provide a theoretical basis for the prevention and control of cellulitis disease. Methods The Global Burden of Disease 2021 (GBD2021) data were collected, and data on the incidence, mortality, and disability-adjusted life year (DALY) of cellulitis were analyzed for each country worldwide. The estimated annual percentage change (EAPC) and age-standardized rate (ASR) were used to estimate the trend change of cellulitis from 1990 to 2021. Results The global burden of cellulitis increased significantly in 2021, with 55.96 million cases, 28.9 million deaths and 876.1 million DALYs, respectively. Incidence and mortality rates were generally higher in males than in females. The incidence and DALYs were higher in high SDI regions, with the highest burden observed in South Asia. In contrast, East Asia exhibited the lowest burden and demonstrated a declining trend. There were significant differences between countries, with India having the highest prevalence, the United States having the highest incidence, and Bahrain having the fastest growing rate.In 2021, China had the lowest age-standardised incidence of cellulitis in the world and the fastest declining age-standardised incidence and age-standardised DALYs. Conclusion The global disease burden of cellulitis is increasing from 1990-2021, and cellulitis remains an an important global public health problem. Targeted preventive meausres should be taken in areas with different economical levels. Men, middle-aged and elderly people, and newborns are the key groups in need of attention and health education.
