Nowadays,acute pancreatitis remains a clinical challenge with considerable morbidity and mortality.Acute pancreatitis is associated with systemic and metabolic derangements which may promote hypermetabolism and negative nitrogen balance due to negative energy balance.Therefore,optimal nutritional support intreatmentof acute pancreatitis has been a subject for decades.Originally,the concept of pancreatic rest by fasting was thought to improve outcome as early enteral nutrition was believed to aggravate inflammation or infection through pancreatic stimulation.At present,an increasing number of studieswere performed showing numerousbenefits of enteral nutrition.In this review,intestinal dysfunctionandroute,timing,type and amount of enteralnutritional support in acute pancreatitis will be discussed.

Objective To study the characteristic cluster structure of good-quality natural drinking water.Methods The coupling 17 O NMR(nuclear magnetic resonance)FWHM(full width half maximum)was selected as the index to weigh the rel-ative average size of water cluster in liquid water.The 17 O NMR FWHM of water samples(nature water and artificial water)were measured by ARX400NMR spectroscopy.Results 17 O NMR FWHMs of21representative water samples were in the range of53-145Hz.Conclusion 17 O NMR FWHM of good-quality natural drinking water mainly lay from70to90Hz.

Objective To investigate the mechanism of melamine-induced renal damage in rats.Methods 48 male SD rats were randomly divided into 4 groups with 12 in each group and feed for 3 months.Group A were the control group,feed with standard granule feedstuff and drinking tap water.Group B were stone-induced group,feed with granule feedstuff containing 3％ Mel and drinking tap water.Group C were feed with granule feedstuff containing 3％ Mel and drinking water containing 2％ taurine.Group D were feed with standard granule feedstuff and drinking water containing 2％ taurine.Every week 24 h urine was collected to test PH,SCr,uric acid,protein,8-IP,H2O2 and Mel level.All rats were sacrificed at the end of 3 months.Blood creatinine detection,renal pathology analysis ( HE and Oil ep-red O dyeing,immunohistochemical) and mitochondria separation and detection were undertaken. ResultsMel was not detedted in urine of Group A and Group D.The urine concentration of Mel in Group B and Group C in 1 week,2 weeks,3 weeks,4 weeks were 3.16 ±0.45,4.39 ±0.213,5.40 ±0.28,5.50 ±3.26 and 3.52 ±0.49,4.32 ± 0.135,5.34 ± 0.40,5.46 ± 2.99 mg/ml,respectively.Compared with Group A,the Mel concentration in urine of Group B and C were drug exposure time dependent.In Group A,the urine protein,urine creatinine clearance,serum creatinine,and renal/weight ratio were 6.45 ± 1.45 mg/24 h,28.0 ± 7.4mmol/l,0.56 ±0.03 ml · min-1 · 100g-1,2.29 ±0.89 mg/g,while in Group B and C,the urinary protein urine,serum creatinine,creatinine clearance,kidney/weight ratio were 14.56 ± 7.69,56.8 ± 5.2,0.29 ±0.05,4.16 ±0.27 and 16.44 ±6.29,55.8 ±7.4,0.30 ±0.07,4.40 ±0.56,respectively.Compared with group A,in Group B and C,the urinary protein increased significantly,urine creatinine clearance reduced,serum creatinine reduced,and renal/weight ratio increased.Compared with Group B,the improvement of renal function in Group C was not significant,and the decrease of serum creatinine and urinary protein were not obvious (P ＞ 0.05).In Group B and C,the urine H2O2,8-IP and mitochondrial oxidatie detection reagent SOD,GSH-PX numerical were 28.5 ± 5.2 mmol/1,3.26 ± 1.6 pg/ml,21.1 ± 7.8 U/mg prot,19.0 ±2.5 energy unit and 26.7 ±4.8 mmol/l,2.99 ±8.5 pg/ml,20.3 ±6.9 U/mg prot,17.9 ±4.8 energy unit,respectively.The difference between Group B and C was not statistically significant (P ＞0.05).Pathological analysis showed Mel was mainly concentrated in crystal tubular lumen (Group B and C),kidney interstitial damage was apparent,and kidney inflammation and fibrosis progressive developed with the increase of the drug exposure time. Conclusions Mel can induce kidney damage and stone formation in rats,and stone was mainly in tubular location in inner medullary zone.It is not the oxidative stress way that Mel leads to kidney damage.

Objective:To explore the effects of myosteatosis and blood glucose (BG) on postoperative complications in non-diabetic gastric cancer patients receiving supplemental parenteral nutrition (SPN) after gastrectomy.Methods:Patients who underwent radical gastrectomy between March 2017 and June 2021 in the Department of Surgical Oncology, the First Hospital of Lanzhou University were included in this study. Various preoperative inflammatory and nutritional indicators, including skeletal muscle metrics at the third lumbar level on CT, were collected retrospectively. Postoperative BG within 3 days and complications within 30 days were monitored. Patients were divided into two groups according to the presence or absence of myosteatosis (assessed via skeletal muscle density [SMD]) and the differences in postoperative BG and complication incidence were compared. Mediation model was used to analyze the mediating effect of BG in the association between SMD and postoperative complications.Results:A total of 357 patients were included in the study. Compared with the 299(83.8%) patients without myosteatosis , the incidence of hyperglycemia, mean BG, maximal BG, and BG fluctuation while on SPN in the 58(16.2%) patients with myosteatosis were higher, and the comprehensive complication index (CCI) and the incidence of complication were higher ( P<0.05). More importantly, BG showed the mediation effect of -0.0892 in the effect of SMD on CCI ( P<0.05), with the effect size of 19.3％. Conclusion:Myosteatosis and postoperative hyperglycemia are associated with higher incidence of complications, and BG plays an intermediary role in the association between myosteatosis and CCI.

Objective To investigate the serum levels of brain derived neurotrophic factor (BDNF) and heat shock protein 70 (HSP70),and evaluate their clinical significance in brain injury of children with complicated febrile convulsions (CFC).Methods Forty-three patients with CFC,41 children with simple febrile convulsions and 36 healthy controls were recruited in this study; their serum levels of BDNF and HSP70 were detected by enzyme linked immunosorbent assay (ELISA); correlation between levels of BDNF and HSP70 and both time of twitch duration and twitch frequency were analyzed.Results The mean serum concentrations of BDNF (4.96±1.21 ng/mL) and HSP70 (2.86± 0.93 ng/mL) in patients of CFC group were significantly higher than those in patients of simple febrile convulsions and healthy controls (P＜0.05); while no significant difference was noted between patients of simple febrile convulsions and healthy controls (P＞0.05).These changes were closely related to the duration time and frequency of convulsions(r=0.553,P=0.015; r=0.587,P=0.012; r=0.526,P=0.024; r=0.562,P=0.018).Conclusions It is sure that some brain injury exists in children with CFC; BDNF and HSP-70 might be one of the molecular mechanisms for the brain injury and protective effect.
