Objective To investigate the effect of three-dimensional conformal intensity-modulated radiotherapy combined with oxaliplatin plus capecitabine chemotherapy upon the postoperative median survival time of patients diagnosed with advanced gastric cancer. Methods A total of 74 patients with advanced gastric cancer admitted to Linyi Central Hospital from February 2010 to January 2012 were recruited and divided into the postoperative chemotherapy group (n＝37) and postoperative radiotherapy and chemotherapy group (n＝37) according to the treatment plan. All patients in two groups were treated with laparoscopic D2radical operation. In the postoperative chemotherapy group, patients were treated with oxaliplatin combined with capecitabine. In the postoperative radiotherapy and chemotherapy group, patients were treated with oxaliplatin combined with capecitabine plus three-dimensional conformal radiotherapy.In both groups, 4 cycles of chemotherapy were delivered. The incidence of adverse reactions, median progression-free survival, median overall survival, and 1-, 3-and 5-year recurrence rate and mortality rate were statistically compared between two groups. Results In the postoperative radiotherapy and chemotherapy group, the incidence rate of bone marrow suppression ( 41%), abnormal liver function ( 30%), nausea and vomiting (30%) and neutropenia ( 46%) did not significantly differ from 35%, 35%, 24% and 41% in the postoperative chemotherapy group ( all P＞0. 05).In the postoperative radiotherapy and chemotherapy group, the median progression-free survival and median overall survival were significantly longer compared with those in the postoperative chemotherapy group (both P＜0. 05).The 1-, 3-and 5-year recurrence rates were 8%, 14%and 16% in the postoperative radiotherapy and chemotherapy group, significantly lower than 32%, 41% and 46% in the postoperative chemotherapy group ( all P＜0. 05).The mortality rate was 11%( 4/37) in the postoperative radiotherapy and chemotherapy group, which was significantly lower than 30%(11/37) in the postoperative chemotherapy group ( P＜0. 05 ). Conclusions Three-dimensional conformal radiotherapy combined with oxaliplatin plus capecitabine chemotherapy can effectively prolong the median survival, reduce the recurrence rate and does not enhance the risk of adverse events for patients with advanced gastric cancer.

Isolated freshly rat islets were transferred to 24-well plates and incubated with different concentrations of glucose or resveratrol for 1 or 24 h.The results showed that resveratrol dose-dependently inhibited glucose-stimulated insulin secretion from isolated rat islets after 1 h incubation,with 10%,35%,and 80% (P<0.05 or P<0.01) decrease at the concentrations of 1,I0,and 100 μmol/L.10 μmol/L resveratrol decreased the intracellular calcium concentration by 60% (P<0.05).After incubation for 24 h,resveratrol increased palmitatesuppressed insulin secretion to 75% (P<0.01) of control.These results suggest that resveratrol acutely inhibits insulin secretion from primary pancreatic islet via regulating intracellular calcium ion concentration,and in the long run resveratrol may protect β-cells from lipotoxicity.

Objective To detect the serum level of vitamin D in infants with atopic dermatitis (AD),and to investigate the relationship between the serum level of vitamin D and severity of AD in infants.Methods Clinical data were collected from patients with moderate to severe AD (AD group)through a questionnaire survey in Children's Hospital of Shanxi from February to April in 2016,and the severity of AD was evaluated by the SCORing atopic dermatitis (SCORAD) score.A total of 95 health checkup examinees served as the control group.Enzyme-linked immunosorbent assay (ELISA)was performed to detect the serum level of 25 (OH) D3 in the AD group and control group,as well as the total serum IgE level in the AD group.Blood cell analyzer was used to determine the proportion of blood eosinophils in the AD group.Results A total of 97 patients with AD were enrolled into the study,including 43 (44.3 ％) patients with moderate AD and 54 (55.7％) patients with severe AD.The serum level of 25 (OH) D3 was significantly lower in the AD group than in the healthy control group ([66.71 ± 21.07] nmol/L vs.[85.43 ± 14.87] nmol/L,P ＜ 0.01),as well as in the patients with severe AD than in the patients with moderate AD ([47.54 ± 29.36] nmol/L vs.[63.89 ± 26.67] nmol/L,P =0.006).The proportion of blood eosinophils was significantly higher in the severe AD group than in the moderate AD group (0.124 ± 0.094 vs.0.061 ± 0.060,P ＜ 0.001).There was no significant difference in the total serum IgE level between the moderate AD group and severe AD group (P =0.375).Among the patients with AD,the serum level of 25 (OH) D3 was negatively correlated with the proportion of blood eosinophils (r =-0.336,P ＜ 0.05),but there was no correlation between the serum level of 25 (OH)D3 and total serum IgE level (r =-0.174,P ＞ 0.05).The serum level of 25 (OH)D3 was significantly associated with breastfeeding and vitamin D supplementation (P ＜ 0.05),but unrelated to age,gender,course of disease and acute exudative phase (all P ＞ 0.05).Conclusion The serum level of 25 (OH) D3 is evidently decreased in infants with AD,and vitamin D deficiency is closely related to the severity of AD in infancy.

The effect of troglitazone on glucose-stimulated insulin secretion (GSIS) in pancreatic β-cells and its mechanism were investigated.10 μmol/L troglitazone had no effect on basal insulin secretion,but significantly decreased GSIS and stimulated AMP-activated protein kinase (AMPK) and acetyl-CoA carboxylase (ACC) phosphorylations (all P<0.01).These reactions were completely reversed by AMPK inhibitor compound C,suggesting that the troglitazone acutely inhibits insulin secretion via stimulating AMPK activity in beta cells.

Objective:To sort out the current status and development of standardized nursing terminology in China, and reveal research hotspots and trends.Methods:The bibliometric and keyword cluster analysis and burstiness detection were performed using CiteSpace software on periodicals of standardized nursing terminology in China National Knowledge Infrastructure, WanFang Database and VIP Database from their establishment to December 31, 2021.Results:A total of 1 761 articles were included. The development process of standardized nursing terminology includes three stages: sprouting period, stagnant period and rapid growth period. Researches were clinically-oriented. Researches focus on clinical application. The main reference tools of the studies include Omaha system, North America Nursing Diagnosis Association-International (NANDA-I) , Nursing Outcome Classification (NOC) and Nursing Intervention Classification (NIC) . Research settings mostly involve the elderly population and specialties such as stroke, diabetes and chronic obstructive pulmonary disease. Research topics focus on transitional care, case management, home visiting and nursing educationbased on nursing process. The Delphi method is commonly used for quality evaluation.Conclusions:Standardized nursing terminology is paid more attention and the overall trend is positive, but the local construction of nursing terminology needs to be developed. It is suggested that future research aim at actual demand of domestic clinical applications, nursing informatics talents be developed and cultivated, and research consensus be gathered in order to promote the construction of a standardized nursing terminology system with Chinese characteristics.

Objective: To investigate the analgesic mechanism of Tuina (Chinese therapeutic massage) by observing the effect of the N-methyl-D-aspartate receptor subunit 2B (NR2B)/postsynaptic density-95 (PSD-95) pathway on the dendritic structure of spinal cord dorsal horn in rats with lumbar disc herniation. Methods: Fifty Sprague-Dawley rats were randomly divided into a blank group, a model group, a Tuina group, a blocker agent group, and a blocker agent + Tuina group. The sciatic nerve chronic constriction injury (CCI) model was prepared by the sciatic nerve ligation method. From the 4th day after modeling, rats in the Tuina group and the blocker agent + Tuina group were subject to daily Tuina intervention, and those in the blocker agent group and the blocker agent + Tuina group were daily intrathecally injected with NR2B blocker agent (MK-801). The spontaneous pain score was used to observe the pain behavior of all rats. The expression levels of NR2B and downstream PSD-95 were measured by immunohistochemistry, and the dendritic structure changes were observed by Golgi staining for rat spinal cord dorsal horn after 14 d of continuous intervention. Results: Compared with the blank group, the degree of rat spontaneous pain after CCI was elevated in both the model and the Tuina groups (P<0.01) and was reduced in the Tuina group after the Tuina intervention compared with the model group (P<0.05). Compared with the model group, the rat spontaneous pain level after blocking NR2B was reduced in both the blocker agent group and the blocker agent + Tuina group (P<0.05). The NR2B and PSD-95 protein levels were significantly higher in the model group compared with the blank group (P<0.01); the total number of dendritic branches was increased (P<0.01), and the total dendritic length became longer (P<0.01) in the spinal cord dorsal horn. The rat NR2B and PSD-95 protein levels were significantly decreased in the Tuina group compared with the model group (P<0.01); the total dendritic branch number was reduced (P<0.01) and the total length was shortened (P<0.01) in the spinal cord dorsal horn. After blocking NR2B, the expression levels of NR2B and downstream PSD-95 protein were significantly lower in both the blocker agent group and the blocker agent + Tuina group compared to the model group (P<0.01). The total branch number was significantly reduced (P<0.01), and the total length was significantly shortened (P<0.01) of the dendrites in the spinal cord dorsal horn. Conclusion: Tuina may exert an analgesic effect by remodeling the dendritic structure in the spinal cord dorsal horn in rats with lumbar disc herniation, and its mechanism may be related to the inhibition of NR2B/PSD-95 signaling pathway.

Objective:To investigate the relationship of plasma cholinesterase (ChE) with triglyceride (TG) levels in newly diagnosed patients with type 2 diabetes (T2DM).Methods:Clinical data and biochemical parameters of 321 patients with newly diagnosed T2DM admitted to the Department of Endocrinology of People′s Hospital of Shanghai Putuo from January 2018 to June 2020 were retrospectively collected. The patients were classified into four groups based on the plasma ChE level: Q1group ( n=81, <6 915 U/L), Q2 group ( n=80, 6 916-8 268 U/L), Q3 group ( n=80, 8 269-9 578 U/L), and Q4 group ( n=80, ≥9 579 U/L). The correlation of plasma ChE with TG level was analyzed. Results:With the increased ChE level, TG level significantly increased ( P<0.001). Correlation analysis showed that ChE was positively correlated with body weight, body mass index (BMI), TG, total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), uric acid (UA), alanine aminotransferase (ALT), aspartate aminotransferase (AST)( r=0.35, 0.39, 0.35, 0.31, 0.27, 0.24, 0.25, 0.11, P<0.05, P<0.01 or P<0.001)while negatively correlated with age, systolic blood pressure, blood urea nitrogen (BUN), creatinine, and glycated albumin (GA)( r=-0.46、-0.14、-0.20、-0.14、-0.21, P<0.05 or P<0.001). Multivariate stepwise regression analysis showed that ChE was an independent risk factor for TG ( β=0.270, P<0.001). Logistic Multivariate regression analysis showed that after adjustment for sex, age, body weight, hemoglobin, leukocytes, total protein, albumin, globulin, ALT, BUN, creatinine, uric acid, smoking history, drinking history, HbA 1C, GA, TC, and LDL-C, the risk of hypertriglyceridemia in Q4 was 6.024 folds higher than Q1 group ( P=0.011). With the TG (1.70 mmol/L) as cut-off value, the optimal cut-off point of the ChE was 7 801 U/L, as calculated by receiver operating characteristic(ROC) curve analysis of ChE and hypertriglyceridemia. Conclusions:ChE level is positively correlated with TG in newly diagnosed patients with T2DM.
