BACKGROUND:The regulation of intestinal flora by exercise is closely related to human health,but intestinal flora involves many factors.Existing studies have lacked consistent evidence on the effect of exercise on the intestinal flora of college students. OBJECTIVE:To explore the effects of exercise on intestinal flora diversity and species composition of college students. METHODS:Through systematic search of PubMed,Web of Science,Embase,Medline,Cochrane Library,CNKI,WanFang Database and VIP database,eight empirical studies were selected and included,and semi-quantitative analysis was performed on them. RESULTS AND CONCLUSION:In terms of the species diversity of the intestinal flora,both high-intensity interval training and Tai Chi exercise significantly enhance the species diversity of intestinal flora in college students,while aerobic exercise does not have a significant effect on the enhancement of intestinal flora diversity in college students.In terms of the species composition of the intestinal flora,all three exercise modalities significantly alter the compositional structure of the intestinal flora in college students,which can increase the abundance of beneficial bacteria such as Ruminalococcus,Faecalis prevotelli,Blautia,and decrease the abundance of harmful bacteria such as Escherichia spp.Compared with high-intensity interval training,aerobic and Tai Chi exercise causes more elevated abundance of beneficial bacteria.In addition to changes in intestinal flora characteristics,exercise improves body composition,cardiorespiratory function,and executive function in college students,and these health benefits are closely linked to exercise-induced changes in intestinal flora that can produce health benefits for the body through metabolic regulation,barrier function,and neuromodulation.Although studies have confirmed the association between exercise and intestinal flora,the mechanism by which exercise affects intestinal flora has not yet been clarified,and at the same time,localizing the flora related to the host health is the key to targeting intestinal flora as a therapeutic target in the future,all of which are worthy of further attention and investigation.

OBJECTIVE To evaluate the influence of pharmaceutical quality control on the efficiency and outcomes of standardized medication therapy management （MTM） services for patients with coronary heart disease by using Economic， Clinical and Humanistic Outcomes （ECHO） model. METHODS This study collected case data of coronary heart disease patients who received MTM services during January-March 2023 （pre-quality control implementation group， n＝96） and June-August 2023 （post-quality control implementation group， n＝164）. Using propensity score matching analysis， 80 patients were selected from each group. The study subsequently compared the economic， clinical， and humanistic outcome indicators of pharmaceutical services between the two matched groups. RESULTS There were no statistically significant differences in baseline data between the two groups after matching （P＞0.05）. Compared with pre-quality control implementation group， the daily treatment cost （16.26 yuan vs. 24.40 yuan， P＜0.001）， cost-effectiveness ratio [23.12 yuan/quality-adjusted life year （QALY） vs. 32.32 yuan/QALY， P＜0.001]， and the incidence of general adverse drug reactions （2.50% vs. 10.00%， P＝0.049） of post-quality control implementation group were decreased significantly； the utility value of the EuroQol Five-Dimensional Questionnaire （0.74± 0.06 vs. 0.71±0.07， P＝0.003）， the reduction in the number of medication related problems （1.0 vs. 0.5， P＜0.001）， the medication adherence score （[ 6.32±0.48） points vs. （6.10±0.37） points， P＝0.001]， and the satisfaction score （[ 92.56±1.52） points vs. （91.95±1.56） points， P＝0.013] all showed significant improvements. Neither group experienced serious adverse drug reactions. There was no statistically significant difference in the incidence of new adverse reactions between the two groups （1.25% vs. 3.75%， P＝0.310）. CONCLUSIONS Pharmaceutical quality control can improve the quality of pharmaceutical care， and the ECHO model can quantitatively evaluate the effect of MTM services， making pharmaceutical care better priced and more adaptable to social needs， thus being worthy of promotion.

Objective: To explore the association between mental health and muscle strength among Chinese adolescents aged 13- 18, providing a theoretical foundation and intervention strategies for mental health promotion. Methods: Data were obtained from the 2019 Chinese National Survey on Students Constitution and Health, including 98 631 Chinese adolescents aged 13- 18. Psychological distress was assessed by using the Kessler Psychological Distress Scale (K10), and mental well being was measured with the Warwick-Edinburgh Mental Well being Scale (WEMWBS). Based on the gender and age specific Z scores of various test items [grip strength, standing long jump, pull ups (for males), and sit ups (for females)], muscle strength index (MSI) was constructed to evaluate the comprehensive level of muscle strength in adolescents. According to the Dual factor Model (DFM) of mental health, participants were categorized into four groups:troubled, symptomatic but content, vulnerable, and complete mental health. Gender differences were analyzed by using Chi-square tests, trends were tested with Cochran-Armitage tests, and multinomial Logistic regression models were applied to assess associations between muscle strength and mental health among adolescents. Results: In 2019, 37.4% of Chinese adolescents aged 13-18 were reported of high mental distress, and 59.9% were reported of low mental well being. Boys had significantly lower rates of high mental distress (35.3%) and low mental well being (55.6%) compared to girls (39.4%, 64.3%), and the differences were of statistical significance ( χ 2=176.13, 780.42, both P <0.05). In 2019, the rate of complete mental health among adolescents showed a downward trend with increasing age ( χ 2 trend = 258.47) and a gradual upward trend with increasing muscle strength levels ( χ 2 trend =123.14)，and both boys and girls exhibited similar trends ( χ 2 trend =103.83, 168.46; 57.00 , 67.34) (all P <0.05). The results of the unordered multiclass Logistic regression model showed that after controlling for confounding factors such as age and gender, when the completely pathological group as a reference, for every 1 unit increase in MSI in adolescents, the likelihood of being in a completely mental health state increased by 29% ( OR = 1.29); for every unit increase in the Z-score for pull ups, the likelihood of being in a completely mental health state increased by 6% ( OR =1.06) among boys; for every 1 unit increase in sit up Z score, the likelihood of being in a completely mental health state increased by 19% ( OR =1.19) among girls (all P <0.05). Conclusions The mental health status of Chinese adolescents is not good enough. Muscle strength is positively associated with mental health.

Hepatic echinococcosis is a chronic parasitic disease, which is caused by the larvae of Echinococcus multilocularis. It has a high risk of disability and mortality, which is also known as "parasite cancer". In clinical practice, hepatic echinococcosis can be divided into hepatic alveolar echinococcosis and hepatic cystic echinococcosis. Hepatic echinococcosis is widely prevalent worldwide. It mainly occurs in the populations residing agricultural and pastoral areas in western China, posing significant threats to the quality of life of local residents. At present, surgery is the main treatment for hepatic echinococcosis in clinical settings. With rapid development of surgical diagnosis and treatment technology and deepening understanding of hepatic echinococcosis, diagnosis and treatment regimens have also been constantly improved. In this article, research progresses on the diagnosis and treatment of hepatic alveolar echinococcosis were reviewed, aiming to provide reference for clinicians, deliver early diagnosis and treatment, mitigate adverse effects of this disease upon patients and improve clinical prognosis.

Tuberous sclerosis complex(TSC)is a rare genetic disease that can lead to benign dysplasia in multiple organs such as the skin, brain, eyes, oral cavity, heart, lungs, kidneys, liver, and bones. Its main symptoms include epilepsy, intellectual disabilities, skin depigmentation, and facial angiofibromas, whilst incidence is approximately 1 in 10 000 to 1 in 6000 newborns. This case presents a middle-aged woman who initially manifested with epilepsy and nodular depigmentation. Later, she developed a lower abdominal mass, elevated creatinine, and severe anemia. Based on clinical features and whole exome sequencing, the primary diagnosis was confirmed as TSC. Laboratory and imaging examinations revealed that the lower abdominal mass originated from the uterus. CT-guided biopsy pathology and surgical pathology suggested a combination of leiomyoma and abscess. With the involvement of multiple organs and various complications beyond the main diagnosis, the diagnostic and therapeutic process for this patient highlights the importance of rigorous clinical thinking and multidisciplinary collaboration in the diagnosis and treatment of rare and challenging diseases.

Objective:To utilize routinely available clinical parameters to uncover the clinical features of different clusters in patients with chronic rhinosinusitis with nasal polyp (CRSwNP) through unsupervised clustering analysis.Methods:The clinical data from 155 CRSwNP patients undergoing nasal endoscopic surgery at Renmin Hospital of Wuhan University from 2021 to 2023 were prospectively collected, including 112 males and 43 females, aged from 7 to 87 years. Unsupervised clustering analysis was conducted using various clinical parameters, including age, gender, smoking and drinking history, local eosinophil (EOS) and neutrophil (NEU) counts, comorbid allergic rhinitis (AR), comorbid asthma, recurrence status, serum-specific IgE, total IgE, cytokine levels, peripheral blood EOS count and percentage, Lund-Mackay CT score, the ratio of CT scores for the maxillary sinus and ethmoid sinus (E/M ratio), visual analogue scale (VAS) score, Lund-Kennedy endoscopic score, and other common clinical indicators to elucidate the clinical characteristics of each cluster. Statistical analysis was conducted using GraphPad Prism 9.5 software.Results:Hierarchical clustering analysis identified four main clusters (Cluster A1-A4), showcasing distinct characteristics such as mild nasal polyps with higher peripheral blood cytokines levels, nasal polyps accompanied by allergies and asthma, a subtype of nasal polyps with high recurrence rates dominated by neutrophils, and nasal polyps with high eosinophil levels. Further subset clustering revealed two clusters of mild polyps (Cluster B1-B2) featuring high cytokine expression and comorbid AR; and two clusters of severe polyps (Cluster B3-B4) presented with severe symptoms, high Lund-Mackay CT score, and high Lund-Kennedy endoscopic score. Variations between Cluster B3 and B4 included symptom complexity, the degree of eosinophil infiltration, and the probability of comorbid asthma. Further clustering analysis for eosinophilic nasal polyps revealed a cluster characterized by highly neutrophilic infiltration and recurrent nasal polyps. The comprehensive analysis of multi-index correlations demonstrated valuable insights into the relationships between common clinical parameters of nasal polyps, providing valuable information for a deeper understanding of the pathogenesis of CRSwNP.Conclusion:The clustering analysis in this study categorizes CRSwNP patients into different clusters based on clinical features and disease outcomes, providing a new perspective for more precise clinical treatment strategies.

Objective:To explore the surgical intervention strategy for metastatic cervical lymph nodes surrounding the carotid artery in head and neck squamous cell carcinoma.Methods:A total of 62 patients with advanced head and neck tumors and carotid wrap by disease treated in Department of Otorhinolaryngology and Head and Neck Surgery, the Affiliated BenQ Hospital of Nanjing Medical University between June 2019 and December 2023 were reviewed, of whom 9 patients presented with metastatic squamous cell carcinoma in cervical lymph nodes of unknown primary or with no recurrence of primary lesion and all the 9 patients were males, aged from 48 to 79 years old, with≤level 2 of Eastern Cooperative Oncology Group-Performance Status (ECOG-PS). Radiographically common carotid artery (CCA) and/or internal carotid artery (ICA) were surrounded by≥270° with tumor. All the 9 patients received implantation of covered stent in carotid artery and radical resection of metastatic cervical lymph nodes. The success rate, complications, surgery-related complications, local recurrence rate, quality of life (QOL) and overall survival (OS) were analyzed. The QOL of patients was compared by paired rank sum test, and P<0.05 indicated statistically significant difference. The OS was analyzed by Kaplan-Meier. Results:The success rate of stent implantation was 100%, with no implantation-related complications. R0 resection was performed in 8 cases and R1 resection in 1 case. The QOL of patients after surgery was improved, and the improvements in "pain", "mood" and "anxiety" were statistically significant( Z values were -2.236, -2.460 and -2.200, respectively, and all P values were<0.05). Follow-up was 1-18 months, with a median of 7 months, and 1 case was lost to follow-up. Local recurrence occurred in 3 patients with an incidence of 37.5% (3/8). OS was 59.9% at 12 months after surgery. Conclusion:Implantation of covered stent in carotid artery combined with radical resection is an effective method for the treatment of cervical lymph node metastasis.

[Objective]To explore the clinical efficacy of modified Yupingfeng Powder combined with western medicine in the treatment of pregnant women with mild corona virus disease 2019(COVID-19).[Methods]The pregnant women with mild COVID-19 admitted to Shanghai Public Health Clinical Center from April 2022 to June 2022 were divided into treatment group and control group randomly.The control group(52 cases)was treated with western medicine such as Vitamin C,and the treatment group(48 cases)was treated with modified Yupingfeng Powder on the basis of control group.A comparison was made between the two groups in terms of each symptoms scores,incidence of adverse pregnancy outcomes and total effective rate.Besides,the levels of laboratory indicators involving lymphocyte,C reactive protein(CRP),interleukin-2 receptor(IL-2R)and interleukin-6(IL-6)were also be compared.The negative changes of virus nucleic acid and disease outcome were observed in the two groups.[Results]Compared with control group,after treatment cessation,the total symptom score in treatment group significantly decreased(P＜0.001),and the total effective rate significantly increased(P＜0.01).The levels of inflammatory markers including CRP and IL-6 decreased significantly in treatment group(P＜0.001,P＜0.01),while the count of lymphocyte increased significantly(P＜0.001).Besides,there was no difference in the incidence of adverse pregnancy outcomes between the two groups(P＞0.05).[Conclusion]Modified Yupingfeng Powder combined with western medicine can significantly relieve the clinical symptoms of pregnant women with mild COVID-19,while shortening nucleic acid negative conversion time and does not affect the pregnancy outcome,which has certain clinical value and is worthy of clinical application.

[Objective]To analyze the value of grey-scale reversed T1-weighted(rT1)MRI in the detection of structur-al lesions of the sacroiliac joint(SIJ)in patients with axial spondyloarthritis(ax-SpA).[Methods]Fifty-two ax-SpA pa-tients who underwent both MRI and CT in our hospital within a week from February 2020 to December 2022 were retrospec-tively included.Both sacral and iliac side of each SIJ on oblique coronal images were divided into anterior,middle and pos-terior portion.Two radiologists reviewed independently three groups of MRI including T1-weighted imaging(T1WI),rT1 and T1WI+rT1 images to evaluate the structural lesions like erosions,sclerosis and joint space changes in each of the 6 re-gions of the SIJ.One of the radiologist did the evaluation again one month later.CT images were scored for lesions by a third radiologist and served as the reference standard.Intra-class correlation coefficients(ICC)were calculated to test the inter-and intra-reader agreement for the assessment of SIJ lesions.A Friedman test was performed to compare the lesion results of MRI and CT image findings.We examined the diagnostic performance[accuracy,sensitivity(SE)and specifici-ty]of different groups of MRI in the detection of lesions by using diagnostic test.A McNemar test was used to compare the differences of three groups of MRI findings.[Results]CT showed erosions in 71 joints,sclerosis in 65 and joint space changes in 53.Good inter-and intra-reader agreements were found in three groups of MRI images for the assessment of le-sions,with the best agreement in T1WI+rT1.There were no difference between T1WI+rT1 and CT for the assessment of all lesions,nor between rT1 and CT for the assessment of erosions and joint space changes(P>0.05).T1WI+rT1 yielded better accuracy and SE than T1WI in detection of all lesions(Accuracy erosions:90.3%vs 76.9%;SE erosions:91.6%vs 76.1%;Accu-racy sclerosis:89.4%vs 80.8%;SE sclerosis:84.6%vs 73.9%;Accuracy joint space changes:86.5%vs 73.1%;SE joint space changes:84.9%vs 60.4%;P<0.05).rT1 yielded better accuracy and SE than T1WI in detection of erosions and joint space changes(Accuracy erosions:87.5%vs 76.9%;SE erosions:88.7%vs 76.1%;Accuracy joint space changes:85.6%vs 73.1%;SE joint space changes:83.0%vs 60.4%;P<0.05).[Conclusions]In the detection of SIJ structural lesions in ax-SpA,rT1 improves the diagnostic perfor-mance and T1WI+rT1 is more superior to others.

Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.
