Objective: To explore the association between takeout fast foods and sugar sweetened beverage consumption with co-occurrence of anxiety and depressive symptoms among first year junior high school students in Yunnan Province, so as to provide theoretical basis for the prevention of anxiety and depressive symptoms co-occurrence among adolescents. Methods: A random cluster sampling involving 8 500 first year junior high school students in 11 counties in Yunnan Province was conducted by a questionnaire survey from October to December 2022. The Depression Anxiety Stress Scale-21 (DASS-21) was applied to assess anxiety and depressive symptoms in first year junior high school students. Chi-square test was used to compare the anxiety-depression co-occurrence symptoms of first year junior high school students with different demographic characteristics. The association between takeout fast foods and sugar sweetened beverage consumption with co-occurrence of anxiety and depressive symptoms of adolescents was analyzed by binary Logistic regression models. Results: The detection rate of co-occurrence of anxiety and depression symptoms among first year junior high school students in Yunnan Province was 26.92%. After controlling for demographic variables and other confounders, takeout fast foods and sugar sweetened beverage consumption( OR=1.50, 95%CI =1.27-1.77) was associated with anxiety-depression co-occurrence symptoms among first year junior high school students in Yunnan Province ( P <0.01). Stratified analysis showed that both Han ( OR=1.37, 95%CI =1.07-1.77) and ethnic minorities ( OR=1.60, 95%CI =1.29-2.00) exhibited statistically significant associations between takeout fast foods and sugar sweetened beverage consumption with co-occurrence of anxiety and depressive symptoms(both P <0.05). Conclusions Takeout fast foods and sugar sweetened beverage consumption increases the risk of co-occurrence of anxiety and depressive symptoms among first year junior high school students in Yunnan Province. It is recommended to strengthen guidance on the consumption of such products among junior high school students to prevent co-occurrence of anxiety and depressive symptoms.

This paper summarizes Professor WANG Yaoxian's experience in treating diabetic kidney disease （DKD） from the perspective of spleen and stomach based on the "internal heat leading to concretions" theory. It is considered that internal heat leading to concretions constitutes the core pathogenesis of DKD， with the spleen and stomach serving as the source of internal heat； therefore， treatment should be based on regulating the spleen and stomach. In the early stage of DKD， dysfunction of the spleen and stomach leads to the initial generation of internal heat. Common syndrome patterns include gastrointestinal heat accumulation and constrained heat in the liver and stomach， for which modified Gegen Qinlian Decoction （葛根芩连汤） can be used to clear heat bind while modified Dachaihu Decoction （大柴胡汤） is used to clear stomach and soothe liver， respectively. In the middle stage of DKD， weakness of the spleen and stomach results in the initial formation of concretions and conglomerations. Common patterns include spleen deficiency with prevalence of dampness and deficiency of both the spleen and kidney. Treatment emphasizes strengthening the spleen and resolving dampness， raising yang and boosting the stomach with modified Shengyang Yiwei Decoction （升阳益胃汤）， or supplementing spleen and boosting kidney， dissipating bind and dispe-ring concretions with modified Shenqi Dihuang Decoction （参芪地黄汤）， respectively. In the late stage of DKD， it is characterized by spleen and stomach depletion， and rampant accumulation of turbidity and toxin， and the common syndrome patterns are damp-turbidity obstruction in the middle jiao （焦） and spleen-kidney yang deficiency. Treatment aims to remove turbidity and harmonize the stomach， or to warm the kidney and strengthen the spleen while elimina-ting turbidity， using modified Dahuang Gancao Decoction（大黄甘草汤） and Jupi Zhuru Decoction （橘皮竹茹汤） or modified Baoyuan Decoction （保元汤） and Lizhong Decoction （理中汤）， respectively. In clinical practice， appropriate formulas and medications are flexibly selected according to specific syndromes.

Objective: To analyze the trend in disease burden attributable to insufficient physical activity among residents in Zhejiang Province from 1990 to 2021, so as to provide evidence for developing targeted prevention and control strategies. Methods: Data on years of life lost due to premature mortality (YLL), years lived with disability (YLD), and disability-adjusted life years (DALY) due to insufficient physical activity among residents of Zhejiang Province were collected from the Global Burden of Disease (GBD) 2021 database. The average annual percentage change was used to analyze the trends in YLL, YLD, and DALY rates from 1990 to 2021. Results: YLL, YLD, and DALY rates attributable to insufficient physical activity among residents of Zhejiang Province increased from 42.65/105, 11.12/105, and 53.77/105 in 1990 to 85.67/105, 31.56/105, and 117.23/105 in 2021, respectively, showing an upward trend (AAPC=2.267%, 3.428%, and 2.517%, all P<0.05). From 1990 to 2021, the YLL, YLD, and DALY rates attributable to insufficient physical activity were consistently higher in females than in males. Both males and females demonstrated upward trends in YLL (AAPC=2.631%, 2.031%), YLD (AAPC=3.711%, 3.268%), and DALY (AAPC=2.840%, 2.303%) rates (all P<0.05). From 1990 to 2021, the YLL, YLD, and DALY rates were highest in the ≥70 years age group. From 1990 to 2021, 15-<50 and ≥70 years age groups showed upward trends in YLL (AAPC=0.439%, 0.818%), YLD (AAPC=3.102%, 1.351%), and DALY (AAPC=1.749%, 0.932%) rates (all P<0.05). The 50-<70 years age group exhibited an increasing trend in YLD rate (AAPC=1.222%), while declining trends in YLL (AAPC=-1.400%) and DALY (AAPC=-0.663%) (all P<0.05). In both 1990 and 2021, the top five diseases attributable to insufficient physical activity in Zhejiang Province were stroke, diabetes, colorectal cancer, ischemic heart disease, and chronic kidney disease. Compared to 1990, the DALY rates for these five diseases increased in 2021, with change rates of 89.20%, 164.84%, 110.67%, 223.40%, and 80.95%, respectively. Conclusions From 1990 to 2021, the overall disease burden attributable to insufficient physical activity in Zhejiang Province showed an upward trend. The disease burden was relatively high among females, the elderly, and for chronic diseases such as stroke, while premature mortality burden declined among residents aged 50-<70 years.

Objective To explore the prevalence of knee osteoarthritis and the influencing fac-tors of comorbidities in people aged ≥60 years old in Chengdu area.Methods A retrospective study was conducted for 168 patients aged ≥ 60 years old with knee osteoarthritis in the hospital from May 2021 to June 2023.Relevant materials of patients with knee osteoarthritis were collected,and preva-lence of the disease was analyzed.Patients were divided into comorbidity group(n=92)and non-co-morbidity group(n=76)based on the comorbidity status.Logistic regression analysis was used to ex-plore the influencing factors of comorbidities.Results Among 168 patients aged ≥60 years old with knee osteoarthritis,there were 107 females(63.69％)and 61 males(36.31％);66 patients(39.29％)were aged 60 to 70 years old,and 102 patients(60.71％)were older than 70 years old;81 patients(48.21％)resided in rural area,and 87 patients(51.79％)resided in urban area;92 patients(54.76％)had one comorbidity at least,specifically including 53 cases of dyslipidemia,38 cases of cardiovascular and cerebrovascular diseases,35 cases of hypertension,28 cases of type 2 diabetes,13 cases of chronic kidney disease,and 11 cases of depression.There were significant differences in age,duration of knee osteoarthritis,body mass index,occupation,history of knee surgery,time of daily physical exercise,knee joint function score,and the proportion of cases preferring spicy and greasy food between the comorbidity group and the non-comorbidity group(P＜0.05).Multivariate Logis-tic regression analysis showed that age(OR=1.561,95％ CI,1.183 to 2.078),body mass index(OR=2.439,95％ CI,1.740 to 3.225),occupation(OR=1.446,95％ CI,1.065 to 1.944),duration of knee osteoarthritis(OR=2.680,95％ CI,1.830 to 3.447),history of knee surgery(OR=1.772,95％ CI,1.313 to 2.336),time of daily physical exercise(OR=1.691,95％ CI,1.221 to 2.174),knee joint function score(OR=2.023,95％ CI,1.573 to 2.859),and prefer-ence for spicy and greasy food(OR=1.842,95％ CI,1.195 to 2.841)were influencing factors of comorbidities in patients with knee osteoarthritis(P＜0.05).Conclusion The knee joint function of people aged ≥60 years old in Chengdu area is poor,and the incidence of complications is high.It is necessary to strengthen the health management of patients with knee osteoarthritis,encourage active exercise,maintain a healthy diet and normal body weight,and reduce the impact of knee os-teoarthritis on their qualities of life.

Objective To explore the effects of graphene quantum dots(GQDs)on the reprogramming of Müller cells.Methods Müller cells were randomly divided into the control,dedifferentiation,dedifferentiation+GQD,and GQD groups.The cells in the dedifferentiation group and the dedifferentiation+GQD group were dedifferentiated using the serum-free medium containing DMEM/F12(1∶1),20 μg·L-1 EGF,10 μg·L-1 bFGF,2 × B27,and 1 × N2 for 5 d.Then,the cells in the dedifferentiation+GQD group and the GQD group were treated with 50 mg·L-1 GQDs for 72 h.The Müller cells in the control group were subjected to normal cell culture.Immunofluorescence staining was used to identify the ex-pression of Müller cell markers,including glial fibrillary acidic protein(GFAP),glutamate-aspartate transporter(GLAST),and glutamine synthetase(GS).Phalloidin staining was performed to observe whether Müller cells could take up GQDs.The effect of different concentrations of GQDs on the proliferation of Müller cells was assessed using the cell counting kit-8(CCK-8)assay.The effect of GQDs on the expression of neural progenitor/stem cell markers(SRY-box transcription factor 2[SOX-2]and Nestin)and the astrocyte marker GFAP in normal and dedifferentiated Müller cells was examined using im-munofluorescence staining and Western blotting.Results The immunofluorescence staining results showed that the fluo-rescence of GFAP was extremely weak and almost invisible in Müller cells,while the fluorescence of GLAST and GS was extremely strong and predominantly appeared in the cytoplasm of Müller cells.After 24 h of GQD treatment,trace amounts of GQD fluorescence were visible in Müller cells.The amount of GQD fluorescence in the cytoplasm of Müller cells gradual-ly increased with time.The CCK-8 assay results showed that the activity of Müller cells tended to decrease with an increase in the treatment time and concentration of GQD.The statistical analysis results showed that the mean fluorescence intensity of GFAP,Nestin,and SOX-2 in Müller cells of the dedifferentiation,dedifferentiation+GQD,and GQD groups was higher than that of the control group,and the differences were statistically significant(all P＜0.05).The mean fluorescence inten-sity of GFAP in the dedifferentiation+GQD group was higher than that in the dedifferentiation group,the mean fluores-cence intensity of Nestin and SOX-2 was lower than that in the dedifferentiation group,and the differences were all statisti-cally significant(P＜0.05).The relative protein expression of GFAP,Nestin,and SOX-2 in Müller cells in the dedifferentia-tion,dedifferentiation+GQD,and GQD groups was higher than that in the control group,and the differences were statis-tically significant(all P＜0.05).The relative protein expression of GFAP in the dedifferentiation+GQD group was higher than that in the dedifferentiation group,the relative protein expression of Nestin and SOX-2 was lower than that in the dedi-fferentiation group,and the differences were statistically significant(all P＜0.05).Conclusion GQDs facilitate the re-programming of Müller cells into astrocytes.

Objective To identify the basic and clinical questions of the Guidelines for Preventive Treatment of Diseases in Endometriosis based on the Delphi method.Methods Based on the preliminary literature review,preliminary pan-research and expert interviews,the questions of the Guidelines for Preventive Treatment of Diseasesin in Endometriosis were drafted.Totally 15 experts were selected for two rounds of Delphi method expert correspondence and the results were statistically analyzed to finalize the questions for inclusion in the guidelines.Results A total of 65 entries were finally identified for inclusion in the guideline questions and condensed into 8 guideline questions.The quality control of the two rounds of Delphi method was good.The positive coefficient of experts in both rounds was 100%.The coefficient of authority of experts was>0.70.In the degree of Delphi coordination,the mean coefficients of variation were 0.23 and 0.26,and the coefficients of Kendall's concordance were 0.510 and 0.309,respectively(P<0.05).Conclusion This study uses two rounds of Delphi method to determine the issues included in the Guidelines for Preventive Treatment of Diseases in in Endometriosis,laying a solid foundation for the subsequent development of the guidelines.

Objective:To analyze the changes and significance in clinical cardiac indicators of early cardiac myocardial dysfunction and cardiac substructure dose during conventional radiotherapy for N 2-N 3 non-small cell lung cancer (NSCLC) with mediastinal lymph node metastases. Methods:The data of 34 NSCLC patients with lymph node metastases in regions 4-8 admitted to the Affiliated Cancer Hospital of Guizhou Medical University from June 2022 to August 2023 were observed and analyzed. All patients were treated with volumetric modulated arc therapy with a prescribed dose of 60-70 Gy. Cardiac troponin T (cTnT) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) were measured at 6 time points: within 1 week before radiotherapy ( t0); when the cumulative radiotherapy dose reaches 20 Gy ( t20), 40 Gy ( t40), 60 Gy ( t60) during radiotherapy; within 1 week after radiotherapy ( tp); 1 month after radiotherapy( tp1). Left ventricular global longitudinal strain (LVGLS) and left atrial global longitudinal strain (LAGLS) were assessed at 4 time points: t0, t40, tp and tp1, respectively. The changes in cardiac indicators at different time points during radiotherapy and their correlation with substructure doses were analyzed using analysis of variance, linear regression analysis, and Pearson correlation. Results:The correlation between cardiac substructure dose and mean heart dose (MHD) in the study cohort in the descending order was as follows: left ventricle ( B=0.43, P<0.001), right ventricle ( B=0.37, P=0.002), left atrium ( B=0.16, P<0.001), and right atrium ( B=0.15, P=0.001). There were significant differences in the changes of LVGLS and LAGLS across different time points ( F=3.13, P=0.029; F=17.18, P<0.001). At 1 month after radiation, LAGLS was significantly decreased compared to pre-radiation levels ( P=0.009), whereas no significant difference was observed in LVGLS ( P=1.000). No significant differences were observed in the changes of cTnT and NT-proBNP across different time points (all P>0.05). Significant correlations were identified between cTnT and right ventricle mean dose at t40 ( r=0.38, P=0.025), as well as between NT-proBNP and right atrium mean dose at t60 and tp ( r=0.54, P=0.001; r=0.41, P=0.016). Conclusions:At present, there is no significant difference between the sensitive serum markers of myocardial injury and LVGLS in detecting early myocardial injury. LAGLS may hold substantial clinical value. There is uncertainty about radiation injury and repair of various cardiac substructures.

Objective To explore the application effect of periodic feedback method in pelvic floor function exercise for patients with low anal preservation.Methods A total of 83 rectal cancer patients with low anal preservation admitted to Zhejiang Cancer Hospital from December 2023 to February 2024 were selected as subjects.They were divided into control group(n=42)and experimental group(n=41)by using a random number table method.The control group received routine health education,while experimental group received guidance on periodic feedback method-based pelvic floor exercises.The compliance with pelvic floor muscle exercises,symptom scores for low anterior resection,and quality of life improvement were compared between two groups.Results After intervention,compliance with pelvic floor exercises was higher,symptom scores for low anterior resection was reduced,overall quality of life was improved in experimental group compared to control group(P＜0.05).Conclusion Periodic feedback method can enhance compliance with pelvic floor exercises and improve overall quality of life for rectal cancer patients with low anal preservation.

Objective:To evaluate the clinical value of 11C-methyl- L-methionine (MET) PET/MR in the differential diagnosis between neoplastic and non-neoplastic brain lesions. Methods:From July 2017 to May 2022, a total of 34 patients (19 males, 15 females, age 8-81 years) who received 11C-MET PET/MR imaging for suspected brain tumors in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology were retrospectively enrolled. Postoperative pathological or clinical follow-up results were used as the gold standard. Diagnostic performance of 11C-MET PET/MR and contrast-enhanced MRI was evaluated by ROC curve analysis and Delong test, as well as the diagnostic performance of PET metabolic parameters (SUV and target to background ratio (TBR)), MRI multi-sequence parameters (cerebral blood flow (CBF), relative CBF (rCBF), apparent diffusion coefficient (ADC), relative ADC (rADC), choline/creatine (Cho/Cr) and choline/ N-acetylaspartate (Cho/NAA)) and their combination. Results:A total of 35 lesions of 34 patients were enrolled, including 12 (34.3%) non-neoplastic lesions and 23(65.7%) neoplastic lesions. The diagnostic sensitivity, specificity, and accuracy for 11C-MET PET/MR were 91.3%(21/23), 12/12, and 94.3%(33/35), in contrast to 16/18, 2/10, and 64.3%(18/28) for contrast-enhanced MRI. Maximum TBR (TBR max) showed the highest discriminative value (AUC=0.877, 95% CI: 0.692-1.000). The combination of TBR max, minimum ADC (ADC min), rCBF, and Cho/NAA could achieve a higher diagnostic performance (AUC=0.918, 95% CI: 0.816-1.000), although the difference was not statistically significant ( Z=-0.42, P=0.676). Conclusion:Multiple quantitative parameters of 11C-MET PET/MR are beneficial to distinguish neoplastic from non-neoplastic brain lesions, and their combination may improve the diagnostic confidence.

Objective:To investigate the clinicopathological and molecular genetic characteristics of intracranial mesenchymal tumors with FET::CREB fusion transcript.Methods:The clinical and imaging data of 6 cases of intracranial mesenchymal tumors with FET::CREB fusion from December 2018 to December 2023 were collected at the First Affiliated Hospital of Zhengzhou University. Their histological features, immunophenotype and molecular characteristics were analyzed.Results:Among the 6 patients, 4 were males and 2 were females, and the median age was 20 years. The clinical symptoms were increased intracranial pressure in 5 cases and epilepsy in 1 case. The lesion sites were cerebellum (2 cases), frontal lobe (2 cases), parietal lobe (1 case), and cranioorbital communication (1 case). The radiological features mainly showed solid or cystic components, with obvious annular enhancement on MRI. The histopathological features showed a wide spectrum of morphology, clear boundaries and fibrous pseudocapsule. The tumor cells were arranged in a lamellar or nodular pattern, and some in cord or loose network. The tumor cells were spindle, oval, epithelioid or stellate. The stroma was collagenous or mucin-rich, and accompanied by abundant lymphocytes and plasma cells infiltration. By immunohistochemical staining, desmin, CD99 and EMA were expressed in 6 cases, CD68 in 1 case, MUC4 in 1 case, synaptophysin in 2 cases, and ALK in 1 case. The Ki-67 proliferation index was between 1%-15%. Molecular analysis showed EWSR1::ATF1 fusion in 3 cases, EWSR1::CREB1 fusion in 2 cases, and EWSR1::CREM fusion in 1 case.Conclusions:Intracranial mesenchymal tumors with FET::CREB fusion are relatively rare and typically occur in children and younger adults. These tumors have a broad morphological spectrum and often express desmin, CD99 and EMA. The molecular characteristics are the gene fusions of FET family (mainly EWSR1, FUS) with CREB family transcription factors (ATF1, CREB1 or CREM). It is necessary to distinguish these tumors from meningiomas and solitary fibrous tumors, and the combination of immunohistochemical staining and molecular genetic testing can effectively help identify these tumors.
