Objective To explore the nutritional status in elderly patients with type 2 diabetes mellitus (T2DM) and analyze its relationship with the risk of sarcopenia. Methods A retrospective analysis was conducted on 312 elderly patients with T2DM admitted to the 904th Hospital of the Joint Logistics Support Force of the People's Liberation Army between January 2023 and December 2025. Based on the presence or absence of sarcopenia, the patients were classified into a sarcopenia group (121 cases) and a non-sarcopenia group (191 cases). The nutritional status and related factors were compared between the two groups. Binary logistic regression analysis was adopted to analyze the correlation and influencing factors. Results The incidence rate of sarcopenia among elderly patients with T2DM was 38.78%. Compared with the non-sarcopenia group, the sarcopenia group had older age and higher proportions of patients with daily activity dependence, coronary heart disease, and gastrointestinal diseases. Conversely, the proportions of patients exercising ≥4 times per week and those paying attention to nutritional knowledge were lower in the sarcopenia group than those in the non-sarcopenia group (P<0.05). The body mass index (BMI), calf circumference (CC), body weight, albumin (ALB), hemoglobin (Hb), and MNA-SF score in the sarcopenia group were lower compared with those in the non-sarcopenia group (P<0.05). After logistic regression analysis, it was found that low BMI, exercising ≥4 times per week, dependence on daily activity, and low ALB and Hb were independent factors influencing sarcopenia in elderly patients with T2DM (P<0.05). Conclusion The incidence rate of sarcopenia is relatively high in elderly patients with T2DM. Low BMI, low ALB, low Hb, reduced weekly exercise frequency, and daily activity dependence are independent related factors. It is necessary to pay clinical attention to nutritional assessment and intervention.

Objective To investigate the impacts of knocking-down Keratin 17(KRT17)on proliferation,apoptosis and epithelial mesenchymal transition(EMT)of bladder cancer cells by regulating Wnt/β-catenin signaling pathway.Methods The expression of KRT17 mRNA and protein in bladder cancer tissue,adjacent tissue,bladder cancer cell lines(5637,T24 and UM-UC-3)and human immortalized urothelial cell line SV-HUC-1 were detected by qRT-PCR and Western blot assay.Immunohistochemical staining was used to detect the expression of KRT17 in the tissues.Cells transfected with NC siRNA and KRT17 siRNA were labeled as the NC siRNA group and the KRT17 siRNA group,respectively.T24 cells treated with 20 mmol/L LiCl were labeled as the LiCl group.T24 cells transfected with KRT17 siRNA and treated with 20 mmol/L LiCl were labeled as the KRT17 siRNA+LiCl group.The non transfected cells were used as the blank group.CCK-8,cloning formation experiment and flow cytometry were applied to detect cell proliferation and apoptosis.QRT-PCR was applied to detect KRT17 mRNA expression.Western blot assay was applied to detect the expression levels of KRT17,β-catenin,Cyclin D1,EMT related proteins Vimentin,E-cadherin and Snail1 proteins.Results The expression of KRT17 mRNA and protein was greatly increased in bladder cancer tissue and cells(P＜0.05).The cell proliferation,colony count,KRT17 mRNA and protein expression,β-catenin,Cyclin D1,Vimentin,and Snail expression were lower in the KRT17 siRNA group than those in the NC siRNA group and the blank group,while apoptosis and E-cadherin expression were higher(P＜0.05).LiCl reversed the inhibition of KRT17 knockdown on the malignant behavior of bladder cancer.Conclusion Knocking-down KRT17 inhibits the proliferation and EMT of bladder cancer cells and promotes their apoptosis by inhibiting Wnt/β-catenin signaling pathway.

OBJECTIVE: To assess the value of non-invasive prenatal testing (NIPT) for the identification of numerical and structural chromosomal abnormalities and copy number variations (CNVs) in fetuses. METHODS: 46 197 pregnant women undergoing NIPT at the Prenatal Diagnosis Center of Chenzhou First People's Hospital from January 2018 to December 2021 were selected as the study subjects. Positive cases were subjected to chromosomal karyotyping and copy number variation sequencing (CNV-seq) following amniocentesis. RESULTS: Nearly 50% of common chromosomal aneuploidies were found in the elder pregnant women. Among these, sex chromosome aneuploidies were mainly found in pregnant women with advanced age as well as borderline risks by serological screening. Rare autosomal aneuploidies and CNVs were mainly found in those with borderline or high risks by serological screening. The positive predictive values (PPV) for fetal chromosomal abnormalities indicated by NIPT were as follows: T21 (92.37%, 109/118), T18 (53.85%, 14/26), sex chromosome aneuploidies (45.04%, 59/131), T13 (34.62%, 9/26), CNVs (29.17%, 14/48), and rare autosomal aneuploidies (2.60%, 2/77). CONCLUSION NIPT has a high detection rate for T21, T18, T13 and sex chromosome aneuploidies. It can also detect rare autosomal aneuploidies and CNVs, including some rare structural abnormalities, though verification is required by analyzing amniotic fluid samples.
