BACKGROUND:Research suggests that exercise interventions may be more advantageous than pharmacologic treatments or dietary restriction alone for fat loss,but fewer studies have simultaneously examined the effects of training modalities and training cycles on visceral and subcutaneous fat in obese populations. OBJECTIVE:To investigate the impact of training modalities and training cycles on visceral and subcutaneous fat in recessive obesity female college students. METHODS:Sixty-three female college students with hidden obesity(body mass index<24 kg/m2 and body fat content percentage≥30%)were recruited from Zhengzhou College of Commerce and Industry,and were randomly divided into a high-intensity intermittent training group(n=32)and a moderate-intensity continuous training group(n=31)using the lottery method.Subjects in both groups performed exercise training of corresponding intensity on a running platform and ensured that the exercise volume of both groups was equal,3 times per week,every 4 weeks as one training cycle for 16 weeks.Before training and at the end of each training cycle,subjects'visceral fat,subcutaneous fat,and overall fat were measured using the corresponding test devices. RESULTS AND CONCLUSION:The repeated measures F results indicated that the main effects of training cycles on visceral fat area,visceral fat index,abdominal subcutaneous fat thickness,percentage of body fat and body mass index were significant,while the main effects of training modalities were significant for subcutaneous fat thickness in the triceps brachii and scapula regions.All the interaction effects between training modalities and training cycles were significant(P<0.05).Results from the simple effect tests revealed that the significant simple effects of training modalities at the 4th and 12th weeks for visceral fat area and visceral fat index,at the 8th and 12th weeks for subcutaneous fat thickness in the triceps brachii,scapula region,and abdominal regions,and at the 8th week for the percentage of body fat and body mass index.Simple effects of training cycles were significant for all measures within each group.(3)The results of multiple comparison tests indicated that in the high-intensity intermittent training group,visceral fat area,visceral fat index,percentage of body fat,body mass index and abdominal subcutaneous fat thickness decreased sequentially at the 4th,8th,12th,and 16th weeks,and subcutaneous fat thickness of the triceps brachii and scapula decreased sequentially at the 8th,12th,and 16th weeks(P<0.05).In the moderate-intensity continuous training group,visceral fat area,visceral fat index,subcutaneous fat thickness of the triceps brachii and scapula,percentage of body fat and body mass index decreased successively at the 8th,12th,and 16th weeks,while abdominal subcutaneous fat thickness decreased successively at the 4th,8th,12th,and 16th weeks(P<0.05).To conclude,both training modalities and training cycles are factors influencing visceral and subcutaneous fat in recessive obesity female college students.Training modality primarily affects subcutaneous fat in the triceps brachii and scapular region,but the fat loss effects may converge over a longer training cycle;training cycle primarily affects visceral fat area,visceral fat index,abdominal subcutaneous fat,body fat content,and body mass index.

ObjectiveTo investigate the current status and development needs of evidence-based medicine （EBM） capability in ethnic minority medicine， and explore effective strategies to enhance EBM capability in this field. MethodsThe questionnaire survey was conducted in various ethnic minority medical institutions and research organisations. The questionnaire covered three dimensions， firstly， perceptions and attitudes towards evidence-based medicine； secondly， advantages and challenges in the development of ethnic minority medicine； thirdly， demands and recommendations for enhancing evidence-based medicine capability in ethnic minority medicine. ResultsA total of 501 valid questionnaires were collected， of which 103 questionnaires were collected by re-sending to minority medicine regions with insufficient participation. The questionnaires included 354 responses （70.66%） from practitioners of minority medicine， including Tibetan medicine， Mongolian medicine， Uyghur medicine， Zhuang medicine， and Korean medicine. Among the 501 questionnaires， 146 respondents （29.14%） indicated that they knew about EBM， 355 respondents （70.86%） had either a "general understanding" or had "not heard about" EBM before， and 469 respondents （93.61%） believed that introducing ECM could promote the development of ethnic minority medicine. The primary challenge in promoting EBM in the field of ethnic minority medicine is the lack of professionals in EBM and a lack of understanding of how to apply it into clinical practice （442 respondents， 88.22%）. In the 9-point importance rating for enhancing evidence-based abilities， high scores were achieved in standardization of clinical practice guidelines （7.50±1.90） and methods for sample sizes in clinical research （7.45±1.90）. Regarding the demand for improving clinical research literacy， expert academic lectures， and experience sharing （404 respondents， 80.64%） and evidence-based methodology monographs on ethnic minority medicine （401 respondents， 80.04%） were emphasized. ConclusionsPractitioners in ethnic minority medicine hold a positive attitude towards integrating EBM. However， there remains substantial room for the education and dissemination of EBM. Enhancing evidence-based capabilities can be achieved through specific measures such as cultivating or recruiting talents in EBM， establishing evidence-based support platforms for clinical research， organizing regular academic lectures and exchanges， and strengthening the construction of theoretical frameworks and evaluation systems tailored to ethnic minority medicine， thereby following a path of evidence-based practices aligned with the unique characteristics of ethnic minority medicine.

It has been proposed by Basic Questions On Proper Therapies for Different Diseases Geographically （《素问·异法方宜论篇》） that "wei （痿） diseases should be treated by Daoyin （导引）". Furthermore， it is clarified that the indications of Daoyin are those conditions related to spleen and dampness caused by dampness pathogen， excessive food intake and less exercise， and mainly manifested as heavy limbs， fatigue and flaccidity， which is similar to the metabolic imbalance in the early stage of glucose or lipid metabolism disorder in modern medicine. Based on modern clinical and basic research evidence， Daoyin can inhibit the response of inflammation， alleviate oxidative stress， regulate intestinal microbiota， and modulate gene expression to improve metabolic abnormalities， and this will provide ideas for researches on the indications of Daoyin.

Background Suicidal ideation serves as a sensitive predictive indicator for non-suicidal self-injury(NSSI)behavior,and NSSI behavior brings profound effects to both mental and physical health of senior high school students.Existing studies have made exploration on the relationship among insomnia,anxiety and NSSI behavior in the general population,but the internal mechanism of NSSI behavior in senior high school students with suicidal ideation requires further study.Objective To explore the pathway of anxiety between insomnia and NSSI behavior in senior high school students,so as to provide references for the intervention on NSSI behavior in such demographic.Methods From December 10 to 15,2021,cluster sampling was adopted to select 2 572 senior high school students across three senior high schools in Hubei Province as the research objects.Assessment was conducted by using Insomnia Severity Index(ISI),Generalized Anxiety Disorder Scale-7 item(GAD-7)and Adolescents Self-Harm Scale.Spearman correlation analysis was conducted to examine the correlation among scores of scales finished by senior high school students with suicidal ideation.Model 4 from the SPSS 20.0 Process 4.2 was employed to test the mediating path of anxiety between insomnia and NSSI behavior.Results A total of 2 421 valid questionnaires(94.13%)were recovered,which revealed 554 cases(22.88%)with suicidal ideation and 408 cases(16.85%)with NSSI behavior.The scores of ISI,GAD-7 and Adolescents Self-Harm Scale of senior high school students with suicidal ideation were higher than those of students without suicidal ideation(Z=17.124,20.611,21.314,P<0.01).As correlation analysis showed,the ISI score of senior high school students with suicidal ideation was positively correlated with scores of GAD-7 and Adolescents Self-Harm Scale(r=0.646,0.354,P<0.01),and GAD-7 score was positively correlated with the score of Adolescents Self-Harm Scale(r=0.375,P<0.01).Among senior high school students with suicide ideation,anxiety acted in a mediating role between insomnia and NSSI behavior,with effect value of 0.111(95%CI:0.053～0.185),accounting for 53.88%of the total effect.Conclusion Insomnia of senior high school students with suicidal ideation can not only directly affect NSSI behavior,but also indirectly affect NSSI behavior through anxiety.

The grading of evidence is an important factor in clinical decision-making. The current evidence grading system based on western medicine is limited in the clinical practice of traditional Chinese medicine （TCM）， therefore we propose the solutions to the development of grading system for TCM interventional evidence， following the international evidence grading standards， taking into considerations of the unique characteristics of TCM practice， based on the Grades of recommendation， assessment， development and evaluation （GARDE） evaluation system， and integrating with grading system regarding TCM classical literature and empirical evidence from modern famous doctors. The evidence from classical literature is suggested to be evaluated from three aspects including source of ancient medical records， comprehensive of treatment details， and the inheritance. The qualification of famous doctors， content integrity， and inheritance of experiences will be used to evaluate the evidence from famous doctors' experience. The multi-sourced evidence such as TCM classical literature， experience of modern famous doctors， and modern researches is mainly integrated in a qualitative way， and the overall level of evidence of TCM interventions will be graded consistently with the GRADE system based on modern research. The evidence from classical literature and modern famous doctors' experience will be assessed and considered as supplementary evidence， which will make the evaluation of clinical evidence more objectively and comprehensively， thereby guiding clinical practice further.

BACKGROUND: Progressive lipid loss of adipose tissue is a major feature of cancer-associated cachexia. In addition to systemic immune/inflammatory effects in response to tumor progression, tumor-secreted cachectic ligands also play essential roles in tumor-induced lipid loss. However, the mechanisms of tumor-adipose tissue interaction in lipid homeostasis are not fully understood. METHODS: The yki -gut tumors were induced in fruit flies. Lipid metabolic assays were performed to investigate the lipolysis level of different types of insulin-like growth factor binding protein-3 (IGFBP-3) treated cells. Immunoblotting was used to display phenotypes of tumor cells and adipocytes. Quantitative polymerase chain reaction (qPCR) analysis was carried out to examine the gene expression levels such as Acc1 , Acly , and Fasn et al . RESULTS: In this study, it was revealed that tumor-derived IGFBP-3 was an important ligand directly causing lipid loss in matured adipocytes. IGFBP-3, which is highly expressed in cachectic tumor cells, antagonized insulin/IGF-like signaling (IIS) and impaired the balance between lipolysis and lipogenesis in 3T3-L1 adipocytes. Conditioned medium from cachectic tumor cells, such as Capan-1 and C26 cells, contained excessive IGFBP-3 that potently induced lipolysis in adipocytes. Notably, neutralization of IGFBP-3 by neutralizing antibody in the conditioned medium of cachectic tumor cells significantly alleviated the lipolytic effect and restored lipid storage in adipocytes. Furthermore, cachectic tumor cells were resistant to IGFBP-3 inhibition of IIS, ensuring their escape from IGFBP-3-associated growth suppression. Finally, cachectic tumor-derived ImpL2, the IGFBP-3 homolog, also impaired lipid homeostasis of host cells in an established cancer-cachexia model in Drosophila . Most importantly, IGFBP-3 was highly expressed in cancer tissues in pancreatic and colorectal cancer patients, especially higher in the sera of cachectic cancer patients than non-cachexia cancer patients. CONCLUSION Our study demonstrates that tumor-derived IGFBP-3 plays a critical role in cachexia-associated lipid loss and could be a biomarker for diagnosis of cachexia in cancer patients.

Objective:To explore independent predictors for poor outcome at 3 months in elderly patients with acute cerebral infarction(ACI)treated with intravenous thrombolysis(IVT), and to develop a nomogram-based predictive model.Methods:This was a retrospective cohort study.Clinical, laboratory and imaging data of 346 elderly patients with ACI treated with IVT from January 2016 to April 2021 in our hospital were collected.Poor outcome was defined as a modified Rankin Scale(mRS)score >2 at 3 months after the stroke.Logistic regression analysis was used to screen for independent factors predicting poor outcome in elderly ACI patients treated with IVT, and a corresponding nomogram model was developed using the R software.The ROC curve, calibration plots and decision curve analysis were used to evaluate discrimination, calibration and clinical application value of the nomogram model.Results:Among 346 candidates, 109 developed a poor outcome, representing a rate of 31.5%.Logistic regression analysis showed that symptomatic hemorrhagic transformation( OR=15.647, 95% CI: 8.913-27.454), stroke severity(moderate stroke, OR=3.322, 95% CI: 1.414-7.811; moderate-severe stroke, OR=8.169, 95% CI: 4.102-16.258; severe stroke, OR=9.653, 95% CI: 5.440-17.121), stroke-associated pneumonia( OR=2.239, 95% CI: 1.134-4.420), and heart failure( OR=2.758, 95% CI: 1.424-5.336)were independent predictors for poor outcome at 3 months in elderly ACI patients treated with intravenous thrombolysis(all P<0.05). With the area under curve(AUC-ROC)value at 0.85(95% CI: 0.80-0.89), the nomogram model, which was composed of the above four predictors, demonstrated good discrimination.On the calibration plot, the mean absolute error was 0.020, indicating that the model had good calibration.Decision curve analysis revealed that the model had good clinical application value. Conclusions:The nomogram model composed of symptomatic hemorrhagic transformation, stroke severity, stroke-associated pneumonia and heart failure may predict poor outcome at 3 months in elderly ACI patients treated with IVT, with high prediction accuracy and high clinical application value.

Objective:To evaluate the characteristics of carotid plaque and the immediate outcomes after carotid artery stenting (CAS) in diabetic and non-diabetic patients by optical coherence tomography (OCT).Methods:Patients underwent CAS and OCT before and after operation in the Department of Neurology, Jinling Hospital from January 2014 to March 2019 were enrolled retrospectively. The clinical features, the characteristics of carotid plaque on OCT and the immediate outcomes after CAS were compared between diabetic group and non-diabetic group. The risk factors of stent malapposition were analyzed.Results:A total of 46 patients were enrolled. Their age was 64.02±8.32 years and 41 were males (89.1%). There were 20 patients (43.5%) in the diabetes group and 26 (56.5%) in the non-diabetes group. The proportions of atherosclerotic plaque with thin fibrous cap (40.0% vs. 7.7%; χ2=5.166, P=0.023), plaque rupture (55.0% vs. 23.1%; χ2=4.945, P=0.026) and macrophage infiltration (60.0% vs. 30.8%; χ2=3.930, P=0.047) in the diabetic group were significantly higher than those in the non-diabetic group. Multivariate logistic regression analysis showed that older age (odds ratio [ OR] 1.208, 95% confidence interval [ CI] 1.033-1.413; P=0.018), coronary heart disease ( OR 15.953, 95% CI 1.142-222.952; P=0.040), alcohol consumption ( OR 6.192, 95% CI 1.098-34.923; P=0.039) and lower systolic blood pressure ( OR 0.944, 95% CI 0.894-0.997; P=0.037) were independently associated with stent malaposition. Conclusion:Compared with the non-diabetic patients, carotid plaque in diabetic patients may be more unstable. Older age, coronary heart disease, alcohol consumption and lower systolic blood pressure were associated with stent malaposition after carotid stenting. OCT can reveal the characteristics of carotid plaque and the immediate outcomes after CAS, which can provide strong evidence for treatment decision.

Objective:To evaluate the efficacy of high-risk HPV (HR-HPV) genotyping with vaginal self-sampling in primary screening and combining cytology or viral load for HR-HPV positive as secondary screening strategies.Methods:The data referring to HR-HPV genotyping of self-collected sample with mass array matrix-assisted laser desorption-ionization time-of-flight mass spectrometry (MALDI-TOF-MS), HR-HPV viral load of physician-collected sample with hybrid capture Ⅱ (HC-Ⅱ), liquid-based cytology and histology of 8 556 women were from Shenzhen cervical cancer screening trial Ⅱ (SHENCCAST-Ⅱ) conducted between April 2009 and April 2010. The data were reanalyzed to determine the sensitivity and specificity to cervical intraepithelial neoplasia (CIN) of grade 2 or worse (CIN Ⅱ +), CIN of grade 3 or worse (CIN Ⅲ +) when HR-HPV genotyping combining with colposcopy as primary screening strategy based on varied HR-HPV subtype (strategy 1, including 5 sub-strategies: 1a: HPV 16/18 positive; 1b: HPV 16/18/58 positive; 1c: HPV 16/18/58/31/33 positive; 1d: HPV 16/18/58/31/33/52 positive; 1e: any HR-HPV positive). The data were also compared to determine the efficacy of cytology (strategy 2, including 5 sub-strategies: 2a, 2b, 2c, 2d, 2e) or HR-HPV viral load (strategy 3, including 4 sub-strategies: 3a, 3b, 3c, 3d) of physician-collected sample as a triage with HR-HPV genotyping for self-sampling HR-HPV positives. Results:(1) The HR-HPV positive rate was 13.77% (1 178/8 556) in the self-collected samples of 8 556 pregnant women. Of them,the prevalences of HPV 16/18, HPV 16/18/58, HPV 16/18/58/31/33 and HPV 16/18/58/31/33/52 were 3.16% (270/8 556), 5.14% (440/8 556), 6.66% (570/8 556) and 9.81% (839/8 556), respectively. The HR-HPV viral load ≥10 relative light units/control (RLU/CO) was 8.87%(759/ 8 556), while cytological results ≥atypical squamous cell of undetermined signification (ASCUS) were 12.05% (1 031/8 556). (2) The strategy 1e had the highest sensitivities for CIN Ⅱ +, CIN Ⅲ + which were 92.70% and 94.33%,respectively,among 14 sub-strategies,while the lowest specificity and positive predictive value (PPV). Meanwhile,the required colposcopy referral rates were much higher than other 13 sub-strategies (13.77%). The other 4 sub-strategies of strategy 1 (1a, 1b, 1c, 1d), strategy 1a had the highest specificities for CIN Ⅱ + and CIN Ⅲ + (97.92%, 97.69%, respectively), while 1d had the highest sensitivities for CIN Ⅱ + and CIN Ⅲ + (88.41%, 92.20%, respectively). (3) Both strategies of referring self-sampling HPV 16/18 positives for immediate colposcopy followed by triage physician-collected sample cytology (≥ASCUS) or viral load (≥10 RLU/CO) for non-HPV 16/18 positives had significantly higher sensitivity and specificity for CIN Ⅱ, CIN Ⅲ +, as well as lower referral rates (strategy 2a and 3a). Additionally, based on these two secondary screening strategies, cumulatively using the other four HR-HPV (HPV 58, 31, 33 and 52) positives as triage for immediate colposcopy showed an enhanced sensitivity. Conclusions:Primary HR-HPV cervical cancer screening strategy based on self-sampling with triage of cytology (≥ASCUS) or viral load (≥10 RUL/CO) provides a good balance among sensitivity, specificity for CIN Ⅱ + and CIN Ⅲ + and the number of tests required, referral rates. The efficacy of HR-HPV genotyping combining cytology or viral load secondary screening strategies will have a spiral escalation when HPV 58, 31, 33, 52 are included.

【Objective】 To retrospectively analyze the irregular antibodies in 6 blood group systems other than the Rh blood group system in 53 pregnant women and analyze its correlation with the occurrence of hemolytic disease of the newborn(HDN). 【Methods】 19 473 pregnant women were screened for irregular antibodies by microgel detection technology combined with anti-human globulin (IgG+ C3d), and the positive samples screened out were further confirmed to understand the types and titers of irregular antibodies. Irregular antibody type determination experiment: IgG type irregular antibody titer was determined after mercaptoethanol (2-Me) inactivated the serum of the irregular antibody positive specimen, and then IgG and IgM type were determined by comparing the titer levels of irregular antibody. Three hemolysis tests and total bilirubin tests were performed on umbilical cord blood during delivery to analyze the level of jaundice and the occurrence of HDN. 【Results】 53 cases of irregular antibodies other than the Rh blood group system were detected in 19 473 pregnant women, with a positive rate of 0.27%, mainly MNS and Lewis blood group system.The incidence of HDN was 39.6% (21/53). There were 27 cases of IgM, 7 IgG, and 19 IgM + IgG. Comparison of total bilirubin detection between the low titer group (≤8) and the high titer group (>8) : the latter was significantly higher than the former (P<0.05); IgG antibody subtypes: IgG1 of the latter significantly increased (P<0.05), and so was IgG3 in former (P<0.05). There was a significant positive correlation between IgG1, IgG3 and total bilirubin. The area under the curve of IgG1+ IgG3 for HDN diagnosis, the sensitivity and specificity were 0.953, 0.900, and 0.967, respectively. 【Conclusion】 Other than Rh blood group system, irregular antibodies are mainly distributed in MNS and Lewis blood group system. The incidence of HDN is higher in Kell, Duffy and Kidd blood group systems after producing irregular antibodies. Non-antibody types are mostly IgM type or IgM + IgG mixed, and the incidence of HDN is not high; Patients with poor maternal history, either high or low titer, can be classified into IgG1 and IgG3 in early stages, and those with Abnormal results should be included into the perinatal management of high-risk women with regular checking.
