Objective There are few researches for the serum betatrophin level and diabetic nephropathy (DN) recently.The aim of this study was to investigate the change of serum betatrophin level and the correlation of serum betatrophin and urinary albumin-to-creatintine ratio (UACR) in patients with type 2 diabetes mellitus (T2DM).Methods A total of 150 Chinese subjects from Mar 2013 to Jul 2016 were enrolled in the study, including 90 patients with type 2 diabetes and 60 healthy controls.According to the level of UACR, the diabetic patients were divided into two groups:normal UACR group (UACR<30 mg/g, n=60) and abnormal UACR group(UACR>30 mg/g, n=30).Serum betatrophin was measured by enzyme linked immunosorbent assay (ELISA).UACR was measured by turbidimetric inhibition immune assay.Blood glucose blood lipid were measured simultaneously.Results The serum betatrophin level was significantly higher in abnormal UACR group than that in normal UACR group[677.37±59.02 vs 486.13±41.22 pg/mL, P<0.05];Serum betatrophin level in T2DM patients was positively correlated with age (r=0.246), waist hip ratio (WHR) (r=0.240), fasting blood glucose (FPG) (r=0.234), 2 hour plasma glucose (2hPG) (r=0.363), glycosylated hemoglobin (HbA1c) (r=0.346), fasting insulin (FINS) (r=0.249), insulin resistance index (HOMA-IR) (r=0.309), blood urea nitrogen (BUN) (r=0.223), creatinine (CREA) (r=0.277) and UACR (r=0.244) (P<0.05),and negatively correlated with glomerular filtration rate (GFR) (r=0.308) (P<0.01).Serum betatrophin level in normal UACR group was positively correlated with age, HbA1c and UACR (P<0.05);Serum betatrophin level in abnormal UACR group was positively correlated with WHR (r=0.504), 2hPG (r=0.600), HbA1c (r=0.449), HOMA-IR (r=0.395) (P<0.05).The WHR, HbA1c, HOMA-IR and GFR were the influential factors of the serum betatrophin level.Conclusion The level of serum betatrophin was significantly increased in T2DM patients with albuminuria, which suggests that the betatrophin might play an important role in the pathogenesis of DN.

Polyglutamine (polyQ) disease is a group of hereditary neurodegenerative diseases. It has become clear that brain damage may occur decades before the onset of symptoms. As a sensitive marker for neuro-axonal damages, neurofilament light chain (NfL) has appeared as a promising biomarker for neurological diseases. it may be used as a preclinical and clinical marker for the neurodegeneration in polyQ diseases, and is closely correlated with disease severity and progression, in particular different disease stages. This article has provided a review for the value of NfL as a biomarker in polyQ disease and its future research directions.

Objective? To explore the effects of symposium involving patients and their family members on health education in patients with acute myocardial infarction after percutaneous transluminal coronary intervention (PCI). Methods? Totally 86 patients with acute myocardial infarction receiving PCI in Ningbo First Hospital from January 2017 to June 2018 were selected continuously and divided into the control group (n=43) and the observation group (n=43). Patients in the control group received conventional health education which combined oral education and education manuals, while patients in the observation group symposium-based health education which involved both patients and their family members on the basis of conventional education after PCI. Both groups received health education for 4 weeks. Health knowledge about acute myocardial infarction, rehabilitation initiative, postoperative complication and satisfaction with overall nursing were compared between the two groups before and after intervention. Results? The health-related knowledge of the patients with acute myocardial infarction in the observation group 4 weeks after intervention scored (94.3±4.0), higher than that of the control group, which was (78.4±5.1), and there was statistically significant difference (t=8.285, P＜ 0.05). The scores of five dimensions of rehabilitation initiative (coordination with therapy, compliance, needs for rehabilitation, emotions post frustration and encouragement from family members and nurses) of the observation group were higher than those of the control group (t=4.726, 5.114, 3.975, 7.116, 5.893; P＜0.05). The incidence rate of postoperative complication in the observation group was 9.30%, lower than that of the control group, which was 30.23%, and there was statistically significant difference (χ2=5.939, P＜0.05). The nursing satisfaction of the observation group was 96.73%, higher than that of the control group, which was 83.78%, and there was statistically significant difference (χ2=4.904, P＜0.05). Conclusions? The symposium involving patients and their family members for patients with acute myocardial infarction after PCI can improve the patients' disease-related knowledge, satisfaction with overall nursing and rehabilitation initiative, and reduce the postoperative complications effectively.

Pancreatic cancer has poor prognosis and lymph node metastasis is a poor prognostic factor in patients with resectable pancreatic cancer. The metastatic prevalence of para-aortic lymph node (PALN) ranges from 9.1% to 26.5% and it is listed as the distant metastatic group in pancreatic cancer. Nevertheless, it is controversial whether PALN metastasis is the contraindication of surgery in resectable pancreatic cancer for the shortage of level Ⅰ evidence.This study concluded that PALN metastasis indicated poor prognosis in patients with pancreatic cancer, but some patients with PALN metastases could benefit from surgery and their survival could be much improved after the combination of surgery and adjuvant therapy. Therefore, it is not wise to refuse surgery for all pancreatic cancer patients with PALN metastasis and the clinicians can cautiously choose the patients to do surgery. Besides, there are mainly retrospective studies rather than prospective and multicenter studies to explore the prognosis of pancreatic cancer patients with PALN metastasis. Thus, more prospective and multicenter studies are needed to decide whether PALN metastasis is an independent prognostic factor in patients with resectable pancreatic cancer.
