ABSTRACT
Objective To explore the correlation of metabolic disorder of newly diagnosed type 2 metabolism(T2DM) and nonalcoholic fatty liver disease (NAFLD).Methods A total of 117 patients with newly diagnosed T2DM in Beijing Ditan Hospital Affiliated to Capital Medical University from June 2014 to June 2015 were enrolled.Patients were divided into two groups:T2DM with NAFLD of 57 cases and T2DM without NAFLD of 60 cases.Body mass index (BMI),waist circumference (WC),liver and kidney function,serum lipid,glycosylated hemoglobin A1c (HbA1c),fasting glucose,fasting insulin and C-peptide (FCP) were detected.The insulin resistance and β-cell function were assessed by homeostasis model assessment insulin resistance (HOMA-IR) and HOMA-β.Results The incidence of NAFLD in T2DM patients was 51％ (that was,60 cases of T2DM patients with NAFLD),compared with 2TDM group,the metabolic index of T2DM without NAFLD was significantly increased (blood triglyceride (TG):(2.58 + 1.8) mmol/1 vs.(1.22 + 0.4) mmol/l,fasting blood glucose:(11.5+6.1) mmol/l vs.(9.2+4.3) mmol/l,serum uric acid:(465.3+65) umol/l vs.(325.3+72) umoL/l;P =0.03,0.03,0.02);HOMA-IR was more serious ((4.9 ± 2.8) vs.(3.8 ± 2.7);P =0.03);insulin β-cell function was compensatory more obvious ((49.2 ± 27) vs.(29.5 ± 18);P =0.02);prevalence rate of obesity,hypertension and diabetic ketoacidosis (DKD),diabetic retinopathy (DR),diabetic peripheral neuropathy(DPN) were significantly increased(P＜0.05).Logistic regression analysis showed that,smoking(OR=1.405,95％CI:1.262-1.567),male(OR=1.037,95％CI:1.015-1.063),BMI(OR=1.113,95％CI:1.278-2.531),WC (OR =1.624,95％ CI:1.162-1.761) and TG (OR =1.823,95％ CI:1.2822.563) were risk factors of NAFLD (P ＜ 0.05).Conclusion T2DM patients with NAFLD have severer insulin resistance than those without NAFLD.The β-cell function of those patients is compensatory increased.NAFLD prevalence rate significantly increase in patients with obesity,especially in male diabetic patients who smoking.
ABSTRACT
Objective To investigate the duration for silicon gastric tube to indwell in stomach of aged patients.Methods One hundred elderly patients needing long-term nutrition support were equally randomized into two groups: control group and observation group.The former had the gastric tubes indwelled in the stomach for 4 weeks and the latter for 3 weeks.The two groups were compared about the used tubes in terms of the color of tube at the length of the first 10cm,the indentation by reflection for 10 seconds at the tube of first 10 cm,the hardness of the tube at the length of the first 10 cm and the springback angle of tube at the first 10cm after reflection.Results The tubes in the observation group were significantly better than those in the control group in terms of color,indentation,hardness and springback angle(all P<0?01).Conclusion The duration of indwelling silicon gastric tubes in stomach can be three weeks for old patients needing long-term nutrition support via indwelling silicon tubes in their stomach.
ABSTRACT
<p><b>OBJECTIVE</b>The growth and repair potential of three typical microorganisms in reclaimed water after UV disinfection was investigated to assess the effects of photo-reactivation and dark repair of microorganisms, and the microbial safety of reclaimed water following this procedure.</p><p><b>METHODS</b>The growth and repair potential of Escherichia coli, a fecal coliform strain and Bacillus subtilis in the effluent of a biological wastewater treatment plant disinfected by a low-pressure UV lamp were investigated.</p><p><b>RESULTS</b>Any increase in bacterial numbers in the effluent after UV disinfection was due to damage repair. Exposure to photo-reactivating light for 8-10 h after UV irradiation with a dose of 5 mJ/cm(2), the highest percentage of photo-reactivation observed for E. coli and the fecal coliform strain was 29% and 15% respectively. B. subtilis showed little photo-reactivation under these conditions. The percentage of photo-reactivation was related to the UV dose and the photo-reactivating time, and a function was developed to forecast the final concentrations of E. coli and the fecal coliform strain after UV disinfection with possible photo-reactivation.</p><p><b>CONCLUSION</b>Different species of bacteria displayed different responses to UV light and different repair potentials. The repair of indigenous bacteria in wastewater needs to be investigated in future work.</p>
