ABSTRACT
Objective To evaluate the effects of low blood sugar production index (LGI) combined with low blood sugar production burden (LGL) dietary intervention on blood glucose, oxidative stress and anthropometric indicators in type 2 diabetes mellitus. Methods A total of 150 cases of type 2 diabetes were randomly divided into two groups,maintain the original treatment plan of two groups,75 patients in the control group were given traditional food interchange method for dietary intervention;the experimental group of 75 patients, provide food education based on LGI+LGI food exchange method , the time period of 3 months. Fasting blood glucose (FPG)、2h postprandial blood glucose (2hPG), Glycated hemoglobin (HbAlc), Superoxide dismutase (SOD), Malondialdehyde (MDA), Vitamin C, Vitamin E, Body Mass Index (BMI), Waist circumference (WC) Upper arm muscle circumference (AMC), Triceps skin fold thickness (TSF) were observed before and after the intervention. Results There were no significant differences in blood glucose, oxidative stress and anthropometry between the two groups (P>0.05). After intervention, in the control group: FPG, 2hPG, HbAlc, SOD, MDA, Vitamin C, Vitamin E, BMI, WC, AMC, TSF were (10.27 ± 2.67) mmol/L, (11.51 ± 2.54) mmol/L, (8.78 ± 1.95)%, (322.73 ± 51.97) kU/L, (5.80 ± 1.76)μmol/L, (40.78±4.86)μmol/L, (19.33±4.79)μmol/L, (23.94±3.18) kg/m2, (89.57±10.23) cm, (24.10± 3.01) cm, (18.38 ± 3.79)mm respectively. In the experimental group: they were (8.76 ± 2.77) mmol/L, (10.63 ± 1.76) mmol/L, (7.96 ± 1.86)%, (357.29 ± 60.04) kU/L, (5.26 ± 1.33)μmol/L, (44.01 ± 7.06)μmol/L, (21.58 ± 5.25) μmol/L, (22.93 ± 2.75) kg/m2, (86.05 ± 10.79) cm, (22.75 ± 2.86) cm, (16.98 ± 4.48) mm respectively. There was significant difference between the two groups after intervention (t=2.049-3.769, all P < 0.05). In the experimental group, the improvement of blood sugar, oxidative stress and anthropometry was better than that of the control group (P < 0.05). Conclusions LGI combined with LGL diet intervention is better than the traditional method of food interchange, the blood glucose, oxidative stress and anthropometric indicators have improved, which can improve treatment efficacy in type 2 diabetes and easy for home self-management.
ABSTRACT
Objective To analyze the clinical features of hepatic veno-occlusive disease (HVOD) and to explore the diagnosis criteria and treatment.Methods A total of 50 cases of HVOD administrated at The First Affiliated Hospital of College of Medicine,Zhejiang University from August 2008 to August 2011 were analyzed for etiology,clinical manifestation,laboratory examination,image,pathological features and treatment.Results Among the 50 HVOD cases,38 cases (76％)had a history of taking Gynura segetum.The main clinical manifestations were ascites,hepatomegaly,right upper quadrant pain,jaundice,and weight gain.Laboratory examinations indicated liver function injury and increased serum CA125 level.Color Doppler ultrasound showed hepatomegaly,decrease in diameter of hepatic vein and slow blood flow.The computed tomography scan suggested hepatomegaly,enhanced scan showed liver inhomogeneous enhancement at portal and delayed phase,map-like changes and markedly decrease in diameter of hepatic vein.Pathological examination suggested hepatic sinusoid congestion,central vein stenosis and vessel wall thickening.The main therapy was anticoagulant treatment.One case cured,33 cases improved,13 cases uncured and three cases died.Conclusions HVOD because of taking Gynura segetum is common in Zhejiang Province,which can be diagnosed according to medical history,clinical manifestations, and typical image characteristic.However,diagnosis of the atypical cases still needs liver biopsy.Anticoagulation therapy can achieve better efficacy.
ABSTRACT
Objective To evaluate the clinical value of endoscopically nasojejunal feeding tube placement (ENFTP) for nutritional support in patients with severe acute pancreatitis (SAP). Methods Those SAP patients who treated with ENFTP (n= 47) or with total parenteral nutrition (TPN) (n=50) were retrospectively analyzed for laboratory parameters before and 1,2 and 4 weeks after nutrition support. Outcomes in the two groups were compared with respect to complications,mortality, duration of feeding, feeding costs,mechanical ventilation time and length of ICU or hospital stay. Results Four weeks after nutrition sypport, the hemoglobin and albumin were increased in ENFTP group as compared to TPN groups (P < 0. 05), while the blood sugar was decreased significant in ENFTP group than in TPN group (P<0.05). The incidence of peripancreatic or biliary infection and catheter-related infection were lower in ENFTP group than in TPN group. Duration of feeding and hospital stay were shorter, and nutrition cost was lower in ENFTP group (P<0.05). In addition, the APACHE Ⅱ score was significantly improved in ENFTP group(P<0.05). Conclusion ENFTP seems to be safe and less expensive in treatment of patients with acute pancreatitis.
ABSTRACT
Objective To compare and analyze gene expression patterns in rat model of nonalcoholic fatty liver disease (NAFLD).Methods Twelve male Sprague-Dawley rats were randomly given either general diet (control group) or a high-fat diet (model group) for 4 weeks.The histopathologic changes of the liver were observed and gene expression patterns were analyzed and compared by cDNA mieroarray.Results Hepatocellular steatosis and inflammatory infiltration were observed in model group after high-fat diet for 4 weeks.Fifty-one differential genes were found in model group,20 of which were up-regulated (sterol regulatory element binding factor 1,stearoyl-coenzyme A desaturase 1 and Bcl 2 modifying factor)and 31 were down-regulated (peroxisomal enoyl coenzyme A hydratase 1,heat shock 70 protein 1A and ATPase inhibitory factor 1). The up-regulating genes were involved in lipogenesis and cell apoptosis,while down-regulated genes were involved in fatty acid oxidation, protein modification and energy metabolism.Conclusions The differential expression of genes may involve in the pathogenesis of NAFLD.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the relationship between genetic polymorphisms of the ethanol metabolizing enzymes and the occurrence of alcoholic liver disease (ALD).</p><p><b>METHODS</b>Sixty-five healthy male controls and 165 alcoholisms (including 122 ALD patients and 43 male alcohol abusers without liver complications defined as alcohol-dependent) were analyzed by polymerase chain reaction and hybridized with oligonucleotide microarray to detect the polymorphisms of the ethanol metabolizing enzymes genes.</p><p><b>RESULTS</b>The frequencies of alcohol dehydrogenase gene 2 * 1 ( ADH2 * 1 ) allele were shown as 37.69%, 46.51% and 59.02% in control, alcohol-dependent and ALD groups respectively; while those of ADH2 * 2 allele were shown as 62.31 %, 53.49% and 40.98% respectively. No ADH2 * 3 was detected in any of the subjects. The frequency of ADH2 * 1 was significantly higher in alcoholisms (ALD group and alcohol-dependent group) than in healthy controls ( P < 0. 01), and significantly higher in ALD group than in alcohol-dependent group ( P < 0.05) . The frequency of ADH3 * 2 was significantly higher in alcohol-dependents than in healthy controls ( P < 0.05) . The frequencies of ALDH2 * 2 allele mutation were significantly lower in alcoholisms than that in the healthy controls, and the deference between ALD group and alcohol-dependent group was significant. No homozygotes for the mutant ALDH2 * 2 allele were found in either alcoholic groups.</p><p><b>CONCLUSIONS</b>Polymorphic ADH2, ADH3 and ALDH2 genes can affect the propensity for alcohol drinking in Chinese. The alleles of ADH2 * 2, ADH3 * 1 and ALDH2 * 2 are most likely to play a protective role against excessive consumption. ADH2 * 2 and ALDH2 X 2 may contribute to susceptibility for ALD.</p>
