In addition,mutation analysis of the whole coding region of NDRG2 in these cancers was examined by polymerase chain reactionsingle strand conformational polymorphism (PCR-SSCP).RESULTS: Compared with adjacent normal tissues, the expression levels of NDRG2 mRNA in corresponding cancer tissues reduced significantly (pancreatic cancer: 0.680±0.112 vs 2.089±0.214, P<0.01) (liver cancer: 0.894±0.098 vs 1.345±0.177, P<0.05). Using PCR-SSCP, the mutation of the whole coding region of NDRG2 was not found in those cancer tissues where the expression of NDRG2 mRNA reduced markedly.CONCLUSION: NDRG2 gene might express differently between normal tissues and cancer tissues, and might play an important role in the development of pancreatic cancer and liver cancer. Low expression of NDRG2 might be unrelated to the mutation of coding region of NDRG2.展开更多

METHODS: Forty-five LADA patients with GAD-Ab positivity screened from phenotypic type 2 diabetic (T2DM) patients and 45 T2DM patients without GAD-Ab matched as controls were followed-up every 6 mo. Sixteen patients in LADA1 and T2DM1 groups respectively have been followed-up for 6 years, while 29 patients in LADA2 and T2DM2 groups respectively for only 1.5 years. GAD-Ab was determined by radioligand assay, and C-peptides (CP) by radioimmune assay.RESULTS: The percentage of patients whose fasting CP(FCP) decreased more than 50% compared with thebaseline reached to 25.0% at 1.5th year in LADA1 group, and FCP level decreased (395.8±71.5 vs 572.8±72.3 pmol/L, P<0.05) at 2.5th year and continuously went down to the end of follow-up. No significant changes of the above parameters were found in T2DM1 group. The average decreased percentages of FCP per year in LADA and T2DM patients were 15.8% (4.0-91.0%) and 5.2% (-3.5 to 35.5%, P= 0.000) respectively. The index of GAD-Ab was negatively correlated with the FCP in LADA patients (rs= -0.483, P = 0.000). The decreased percentage of FCP per year in LADA patients were correlated with GAD-Ab index, body mass index (BMI) and age at onset (rs = 0.408, -0.301 and -0.523 respectively, P<0.05). Moreover, GAD-Ab wasthe only risk factor for predicting βcell failure in LADA patients (B = 1.455, EXP (B) = 4.283, P = 0.023). CONCLUSION: The decreasing rate of islet β cell function in LADA, being highly heterogeneous, is three times that of T2DM patients. The titer of GAD-Ab is an important predictor for the progression of islet β cell function, and age at onset and BMI could also act as the predictors.展开更多

Methods: 58 cases of hypothermia newborns delivered in our hospital from June 2019 to March 2022 were included. They were randomly divided into two groups. The reference group (n 29) carried out routine nursing and the test group (n 29) carried out birds nest kangaroo type bathing transport combined nursing. After nursing, the blood gas index, body temperature improvement, complications and family care satisfaction of the two groups were compared. Results: after nursing, the blood oxygen saturation (SpO2) and arterial blood oxygen partial pressure (PaO2) in the test group were significantly higher than those in the reference group P 0.05 (t 2.806, t 2.853);The body temperature of the experimental group on the 1st, 7th, 14th and 24th day of birth was significantly higher than that of the reference group (P 0.05) (t 9.157, t 15.211, t 6.608, t 4.981);The incidence of complications in the test group was also significantly lower than that in the reference group (P 0.05)( χ24.061);Compared with the reference group, the nursing satisfaction of family members of newborns in the test group was significantly higher (P 0.05)( χ 24.061). Conclusion: the combined application of birds nest kangaroo bath transport nursing care for hypothermia newborns can effectively reduce their oxygen consumption, improve blood gas indicators, promote the recovery of childrens body temperature, reduce complications, and improve the satisfaction of family members with nursing care, which is worthy of promotion.展开更多
