Objective To investigate the impact of nutritional risk-based intervention on the quality of life and survival prognosis of patients with the locally advanced pancreatic cancer and undergoing the chemotherapy.Methods A total of 118 patients with the pancreatic cancer and admitted to the Department of Hepatobiliary and Minimally Invasive Surgery,Lincang People's Hospital from April 2021 to April 2024 were selected and randomly divided into the nutritional intervention group and the control group,with 59 patients in each group.All patients received the palliative chemotherapy,and the control group received the routine dietary guidance,while the intervention group received the nutritional intervention based on the nutritional risk score.The nutritional status,quality of life score,and survival prognosis of the two groups were compared.Results The NRS2002 score of the intervention group and the control group gradually increased from the first to the sixth chemotherapy,and the NRS2002 score of the intervention group was lower than that of the control group at the 4th,5th,and 6th chemotherapy(P<0.05).The incidence of malnutrition in the intervention group was lower than that of the control group at the 1st,2nd,and 3rd chemotherapy(11.9%,30.9%,and 32.2%,respectively),but there was no significant difference(P>0.05);The incidence of malnutrition in the intervention group was significantly lower than that of the control group at the 4th,5th,and 6th chemotherapy(32.2%,45.8%,and 52.5%,respectively),while the incidence of malnutrition in the control group was 59.3%,69.5%,and 88.5%,respectively(P<0.05);The quality of life score of the intervention group in all dimensions was significantly higher than that of the control group after the treatment(P<0.05).After the nutritional intervention,the median OS time and median PFS time of the patients were significantly improved(P<0.05).Conclusion Nutritional intervention can reduce the nutritional risk during the chemotherapy for locally advanced pancreatic cancer patients and improve their quality of life.

Objective:To explore the effects of type 2 diabetes mellitus (T2DM) on the levels of serum magnesium in patients with community-acquired pneumonia (CAP) and the effects of abnormal serum magnesium on the prognosis in T2DM patients with CAP.Methods:The study was a retrospective single-center study conducted in adult patients hospitalized with CAP at the First Hospital of Qinhuangdao between January 2015 and December 2018. These patients were divided into two groups according to the diagnosis of T2DM (control group and T2DM group). The reference range for serum magnesium is from 0.75 to 1.25 mmol/L. The primary endpoint was in-hospital mortality.Results:The prevalences of hypomagnesemia and hypermagnesemia were numerically higher in T2DM group than in control group (hypomagnesemia: 14.6% vs 12.0%, hypermagnesemia: 1.4% vs 0.7%), but there was no statistical difference ( P>0.05). In patients with T2DM, the in-hospital mortalities in patients with normal serum magnesium and hypomagnesemia were 5.9% and 12.7%, respectively; In multivariate logistic regression analysis, the in-hospital mortality of patients with hypomagnesemia was 5.629(95% CI 2.012-15.750, P=0.001)times as much as that of patients with normal serum magnesium. Conclusions:Abnormal serum magnesium was common in T2DM inpatients with CAP and hypomagnesemia was the most common. Hypomagnesemia was closely related to in-hospital mortality in T2DM patients with CAP. The assessment of serum magnesium levels on admission may be helpful in predicting the prognosis of T2DM patients with CAP.

To explore the best measurement of waist circumference related with intra-abdominal fat area evaluated by magnetic resonance imaging ( MRI). Totally 207 participants aged 20-60 years were enrolled. Waist circumference were measured at the levels of navel ( WC1) and the midpoint between costal brim and iliac cest (WC2). Intra-abdominal fat area was evaluated by MRI scan. Intra-abdominal fat area was significantly higher in men than in women [(132. 17 ± 59. 49 vs 70. 56 ± 35. 33)cm2 , P<0. 01]. Pearson correlation analysis showed that WC1 and WC2 were positively correlated with intra-abdominal fat area (r = 0. 779, r = 0. 809, both P<0. 01). Multiple linear stepwise regression analysis demonstrated that WC1 and WC2 were independently associated with intra-abdominal fat area(β=0. 553, R2 =0. 714, P<0. 01; β = 0. 603, R2 = 0. 735, P<0. 01). All of the two different measurements of waist circumference parameters may reflect intra-abdominal fat area, while WC1 seems to be the simpler one.

BACKGROUND:Osteoarthritis is an age-related joint disease characterized by articular cartilage degeneration.
OBJECTIVE:To assess the expression of miR-140-3p in synovial fluid of knee osteoarthritis, and identify whether miR-140-3p levels in synovial fluid are correlated with disease severity.
METHODS:We col ected 10 healthy volunteers, 10 patients with gouty arthritis, 10 patients with rheumatoid arthritis, and 45 patients with knee osteoarthritis (15 cases in early stage, 15 cases in middle stage and 15 cases in the late stage). Real-time fluorescence quantitative PCR was used to detect miR-140-3p expression in synovial fluid in each group.
RESULTS AND CONCLUSION:(1) Expression of miR-140-3p was significantly down-regulated in knee osteoarthritis group. Significant differences in miR-140-3p expression were detected between non-knee osteoarthritis group and knee osteoarthritis group (P<0.05). No significant difference in miR-140-3p expression was determined among healthy control group, gouty arthritis group and rheumatoid arthritis group (P>0.05). (2) The miR-140-3p expression in the healthy control group was 11.4 times that in the knee osteoarthritis group. The expression of miR-140-3p decreased with the increase of the severity of osteoarthritis. (3) Spearman rank correlation analysis suggested that the expression of miR-140-3p was negatively correlated with osteoarthritis severity. (4) Results suggest that the expression of miR-140-3p in synovial fluid can reflect the progression of knee osteoarthritis to a certain extent.

OBJECTIVETo study the expression of EpCAM and E-cadherin in papillary thyroid carcinoma and to analyze its correlation with various clinicopathologic parameters.

METHODSImmunohistochemical study for EpCAM and E-cadherin was carried out in 91 cases of papillary thyroid carcinoma. Twenty-four cases of papillary hyperplasia of thyroid were used as controls.

RESULTSIn all of the 24 cases of papillary hyperplasia, EpCAM was located on the cell membrane, while in the 91 cases of papillary thyroid carcinoma studied, EpCAM was located within the cytoplasm, with 36.3% (33/91) showing nuclear localization as well. In all the papillary hyperplasia cases studied, E-cadherin showed membranous expression. E-cadherin expression was reduced in 84.6% (77/91) of papillary thyroid carcinoma, as compared with the surrounding native thyroid parenchyma. Amongst the 33 cases of papillary thyroid carcinoma which showed nuclear localization of EpCAM, 30 cases also showed reduced E-cadherin expression. There was a positive correlation between nuclear expression of EpCAM and loss of E-cadherin expression (P = 0.000; Spearman correlation coefficient = 0.857). Nuclear expression of EpCAM correlated with follicular variant of papillary thyroid carcinoma and presence of extrathyroidal extension ( P = 0.037 and 0.033, respectively). Loss of E-cadherin expression correlated with age of patients and presence of lymph node metastasis (P = 0.018 and 0.010, respectively).

CONCLUSIONSE-cadherin expression is reduced in papillary thyroid carcinoma, as compared with native thyroid parenchyma and papillary hyperplasia. Papillary thyroid carcinoma shows loss of EpCAM membranous expression and increased cytoplasmic/nuclear accumulation. Detection of these two markers may provide a valuable reference in defining the biologic behaviors of papillary thyroid carcinoma, including extrathyroidal extension and lymph node metastasis.

Objective The aim of the study was to explore the relationship between hypertriglyceridemic-waist(HTWC) phenotype and clustering of cardiovascular risk factors in adolescents. Methods A cross-sectional study was conducted in 3 136 Han adolescents aged 13-17 years in Qinhuangdao. The HTWC phenotype was defined as serum triglyceride concentrations ≥1. 47 mmol/ L and waist circumference ≥90 th percentile for age and sex. Results The prevalence of HTWC phenotype was 3. 3% . The prevalence of clustering of cardiovascular risk factors was 0. 4%in adolescents with normal waist circumference and serum triglyceride and 14. 7% in adolescents with HTWC phenotype. After adjustment for sex, age, body mass index, and family history of diabetes and hypertension, the prevalence of clustering of cardiovascular risk factors in adolescents with HTWC phenotype was 9. 286 fold(95% CI 3. 161-27. 282, P<0. 01) of that in adolescents with normal waist circumference and triglyceride. Conclusion There was a significant correlation between HTWC phenotype and clustering of cardiovascular risk factors, suggesting that this phenotype may be applied as a simple marker for identifying adolescents with clustering of cardiovascular risk factors.
