Objective: To investigate the correlation between the consumption of milk tea and takeaway on overweight and obesity of college students, so as to provide a scientific basis for effective prevention and control of overweight and obesity among college students. Methods: A questionnaire survey and physical test were conducted among 14 379 college students from 7 universities in Shanghai, Jiangxi, Hubei and Shanxi provinces from October to November 2023 by the convenient sampling method. The self designed questionnaires on milk tea consumption and takeaway consumption were used to investigate the consumption of milk tea and takeaway among college students. The χ 2 test was used to compare the distribution difference of the detection rate of overweight and obesity among college students in different groups and different consumption frequency of milk tea and takeaway. Multivariate Logistic regression analysis was used to analyze the correlation between the consumption of milk tea takeaway and overweight and obesity. Results: The prevalence of overweight and obesity among college students was 24.29%. The prevalence of overweight and obesity among college students was statistically significant among gender, grade, single child or not and family economic status ( χ 2= 308.72 ,38.83,15.49,16.82, P <0.01). In addition, there were statistically significant differences in the prevalence of overweight and obesity with different takeaway consumption frequency and milk tea consumption frequency among college students ( χ 2=21.32,46.32, P <0.01). Multivariate Logistic regression model showed that different consumption frequency of milk tea (1-3, 4-5, ≤6 times for every week) were positively correlated with overweight and obesity( OR =1.62,1.75,2.39), and eating takeaway every day was also positively correlated with overweight and obesity ( OR =1.32)( P ＜0.01). Interaction analysis showed that frequent joint consumption of milk tea and takeaway was positively correlated with overweight and obesity of college students ( OR =3.00, P ＜0.01). Conclusions The consumptions of milk tea and takeaway are associated with overweight and obesity among college students. Colleges and relevant departments should take effective measures to intervene in overweight and obesity among college students.

Objective To explore the influence of miR-200 c on the biological behavior of laryngeal carcinoma Hep-2 cells and determine whether miR-200 c exerts its biological function through peptidyl-prolyl cis/trans isomerase (PIN1) in laryngeal carcinoma. Methods A qRT-PCR assay for the expression of miR-200 c was performed in laryngeal carcinoma tissues. Hep-2 cells were transfected with miR-200 c related small RNAs. Transwell assay detected the migration ability of the cells. Immunofluorescence assay was used to detect the abnormal amplification of the centrosome. A dual luciferase reporter gene system was used to detect the binding ability between miR-200 c and PIN1. Western blotting detected the protein expression level of PIN1. Results The expression of miR-200 c in laryngeal carcinoma was significantly increased. miR-200 c inhibited the migration of Hep-2 cells and could weaken the abnormal amplification of centrosome.PIN1 was confirmed as one of the target genes of miR-200 c. miR-200 c inhibited the expression of PIN1 at the translation level and could inhibit Hep-2 cell migration and abnormal centrosome amplification by regulating PIN1. Conclusion miR-200 c can inhibit the migration ability of laryngeal carcinoma cells and abnormal centrosome amplification by regulating PIN1.

Objective To study the consistency between pathology and the single and combined diagnosis of negative breast cancer by ultrasonography and mammography.Methods 90 clinical case data of patients with palpable negative breast tumors and mammography revealed small calcifications were retrospective analyzed.All patients were received the high frequency ultrasound.The value of two methods and combined diagnosis in the diagnosis of breast cancer with palpation negative were compared,which the pathological biopsy was the gold standard.Results The pathological showed that there were 58 cases of benign tumors,32 cases of malignant tumors,10 cases of stage 0,18 cases of stage Ⅰ,4 cases of stage Ⅱ.The high frequency ultrasonography was consistent with pathological(Kappa =0.641).The AUC of diagnosiing the breast cancer was 0.775.The molybdenum target radiography was consistent with pathological (Kappa =0.725),and the AUC was 0.830.The high frequency ultrasonography combined with molybdenum target radiography was highly consistent with pathological(Kappa =0.879),and the AUC was 0.934.The accuracy of combined diagnosis was higher than that of high frequency ultrasound (P ＜ 0.05) and molybdenum target radiography(P ＞ 0.05).Conclusion The high frequency ultrasonography and molybdenum target radiography have advantages in the diagnosis of palpable negative breast cancer.The joint diagnosis helps to achieve complementary strengths,has high consistency with pathology,and help to improve the diagnostic accuracy.

Objective To investigate the expression and clinical significance of Th17 and Tc17 cells in peripheral blood of lung cancer patients.Methods The percentages of Th17 cells and Tc17 cells in 60 lung cancer patients and 40 healthy controls were evaluated by flow cytometry analysis (FCM).Results The percentages of Th17 cells [(1.795±0.623) ％] and Te17 cells [(0.865±0.357) ％] in lung cancer group were significandy higher than those in controls [(1.405±0.256) ％,(0.640 ±0.204) ％],(t =28.944,P ＜ 0.001,t =14.051,P ＜ 0.001).Furthermore,there was a positive correlation between Th17 cells and Tc17 cells in the two groups (lung cancer group r =0.770,P ＜ 0.05,control group r =0.532,P ＜ 0.05).The percentages of Th17 cells and Tc17 cells were closely associated with clinical stage (F =4.882,P =0.011,F =3.633,P =0.033),but not connected with pathological types (P ＞ 0.05,P ＞ 0.05).Conclusion The overexpression of Th17 and Tc17 may be involved in the occurrence and development of lung cancer,which can be used as new indicators for immunologic function of lung cancer patients,and provide a reference in monitoring the disease.

OBJECTIVE: To investigate the expression of breast cancer metastasis suppressor 1 (BRMS1) gene protein and the expression of BRMS1 gene promotor area methylation in supraglottic cancer and to evaluate its clinical significance. METHOD: The expression of BRMS1 protein and BRMS1 gene promotor area methylation were examined by using Western blotting method and methylation-specific polymerase chain reaction(MSP) method in 70 cases of supraglottic cancer tissues and 60 cases of their surrounding laryngeal normal mucosa tissues (LNT) and 44 cases of cervical lymph node metastasis of supraglottic cancer. RESULT: Western blot results indicate that BRMS1 protein expression is declined expression level in supraglottic cancer tissue than the expression of BRMS1 protein in LNT of supraglottic cancer. Compared with para carcinoma normal laryngeal mucous tissue, BRMS1 gene protein in supraglottic cancer tissue primary lesion decreased obviously, and it is decreased more obviously in cervical lymph node metastasis lesion, the discrepancy is notable (P < 0.05). MSP results indicate BRMS1 gene promotor methylation is coordinated with its down-expression in supraglottic cancer tissue. BRMS1 promotor area methylation analysis reveal that there were 34 patients with methylation in 70 patients' supraglottic cancer tumor primary lesion, hold 48.6% (34/70); 32 patients have methylation in 44 patients' cervical metastasis lymph node tissue, hold 72.7% (32/44); however, there is no methylation in 60 para carcinoma tissue (r(s) = 0.66, P < 0.05). CONCLUSION The expression of BRMS1 protein in supraglottic cancer is significantly decreased. It had correlation with clinical stage and pathologic differentiation and cervical lymph node metastasis of supraglottic cancer. BRMS1 gene promotor methylation is related with down-expression of BRMS1 gene protein of supraglottic cancer. Maybe BRMS1 gene promotor methylation is one of the reasons of its down-expression.

OBJECTIVE: To investigate the expression of breast cancer metastasis suppressor 1 (BRMS1) and CD44v6 protein in supraglottic cancer and to evaluate its clinical significance. METHOD: The expression of BRMS1 protein and CD44v6 protein were examined by using immunohistochemical method in 70 cases of paraffin-embedded supraglottic cancer tissues and their surrounding laryngeal normal mucosa tissues (LNT). RESULT: The expression of BRMS1 protein in LNT of supraglottic cancer was positive, and the positive rate was 85.7% (60/70); in tumor tissue was negative or lower expression, and the positive rate was 35.7% (25/70). The expression of CD44v6 protein in tumor tissue of supraglottic cancer was positive, the positive rate was 82.9% (58/70), in LNT was negative. There was a significant difference in BRMS1 and CD44v6 protein expression between the supraglottic cancer tissue and LNT (P<0.01). The expression of BRMS1 and CD44v6 protein had correlation with clinical stage and pathologic differentiation and cervical lymph node metastasis of supraglottic cancer (P<0.01). No correlation was found between the two proteins expression and sex and age (P>0.05). The expression of BRMS1 protein was related to the expression of CD44v6 protein (r = -0.9042, P<0.01). Calculated by Kaplan-Meier method, there is no survival difference at 3-year between the group with positive BRMS1 protein expression and the group with negative BRMS1 protein expression in tumor tissues (P>0.05), there is a significant survival difference at 3-year between the group with positive CD44v6 protein expression and the group with negative CD44v6 protein expression in tumor tissues (P<0.05). CONCLUSION The expression of BRMS1 protein in supraglottic cancer is significantly decreased and the expression of CD44v6 protein in supraglottic cancer is significantly increased. The expression of BRMS1 protein and CD44v6 protein has a close relationship with pathologic differentiation and clinical stage and cervical lymph node metastasis of supraglottic cancer. Combined detection of the expression of them in supraglottic cancer may provide a significant parameter to judge the cervical lymph node metastasis of supraglottic cancer.

OBJECTIVETo investigate the association of mutations and expression of MUS81 gene with the tumorigenesis and progression of laryngeal squamous cell carcinoma (LSCC).

METHODSPCR-SSCP and DNA sequencing were carried out to examine mutations at exons 9 and 10 of MUS81 gene in 42 LSCC samples, with paired adjacent normal laryngeal tissues (PANLs) as control. Semi-quantitative RT-PCR and Western blot were used to detect the expression of MUS81 gene in the specimens.

RESULTSNo mutation was detected in the control group. Among the 42 LSCC specimens, nineteen (45.2%) were found to harbor mutations, including 11(26.2%) occurring within exon 9, and 8 (19%) within exon 10. Seventeen (40.48%) samples showed lower mRNA level of the MUS81 gene (P<0.01), and same proportion of samples had lower protein level (P<0.01), suggesting that MUS81 gene was similarly down-regulated at both mRNA and protein levels in the LSCC samples. Furthermore, mutations of MUS81 gene did not significantly correlate with TNM stages, age and lymphoid node metastasis (P>0.05). Nor did the expression of MUS81 gene with the TNM stages, age and lymphoid node metastasis in LSCC (P>0.05).

CONCLUSIONMutations and abnormal expression of MUS81 gene in the LSCC tissues were observed, which suggested that abnormalities of MUS81 gene may play an important role in the tumorigenesis of LSCC.

OBJECTIVE: To investigate the expression of breast cancer metastasis suppressor 1 (BRMS1) mRNA in supraglottic cancer and to evaluate its clinical significance. METHOD: The expression of BRMS1 mRNA was examined by using RT-PCR method which take beta-actin mRNA as reference template in 66 cases of supraglottic cancer tissues and their adjacent normal mucosa tissues (ANT). RESULT: The expression of BRMS1 mRNA in the tissues of supraglottic cancer is lower significantly than that in the tissues of ANT ( P<0.05). There is correlation between BRMS1 mRNA expression and the clinical stage, differentiation and cervical lymph node metastasis in the laryngeal supraglottic cancers (P<0.05). There is no correlation between BRMS1 mRNA expression and sex and age. CONCLUSION Expression of BRMS1 mRNA in supraglottic cancer is lower than that in adjacent normal mucosa. The decrease of BRMS1 mRNA expression may be related to clinical stage and low differentiation and lymph node metastasis of supraglottic laryngeal cancer.
