When given intraperitoneally, it also showed hypoglycemic activity- For alloxan diabetic mice, thepolysaccharide can also markedly lower its b1ood sugar by gastric gavage.

Objective To determine the relationship between zinc and nutritional status or immunity in patients with end-stage renal disease undergoing continuous ambulatory peritoneal dialysis (CAPD). Methods Forty-five stable CAPD patients undergoing peritoneal dialysis were enrolled in this study. The dietary zinc intake and serum zinc levels were investigated, and the results were compared with the gender- and age-matched healthy populations (n = 45). The relationship between dietary zinc intake and serum zinc levels and subjective global assessment (SGA) score, blood cell counts, serum albumin (ALB), prealbumin (PA), C-reactive protein (CRP),and lymphocyte subsets were analyzed. Results The percentages of inadequate dietary zinc intake (P= 0. 007)and low blood zinc (P = 0. 036) were significantly higher in CAPD patients than in healthy group. CD8 levels were significantly lower (P = 0. 000) while CD4/CD8 ratio was significantly higher (P = 0. 033) in CAPD patients than in healthy group. In CAPD patients, correlation analysis showed that dietary zinc intake was significantly correlated with serum prealbumin levels (r = 0. 577, P = 0. 000), but was negatively correlated with SGA score (r = - 0.354,P = 0. 015) and CRP (r = - 0.354, P = 0. 015); however, it was not significantly correlated with lymphocyte subsets and CD4/CD8 ratio. Serum zinc level was significantly positively correlated with hemoglobin (r= 0. 411, P=0.005), hematocrit (r=0.345, P=0.023), WBC (r=0.318, P=0.035), SGA score (r=0.417, P=0. 005), and CRP (r=0.342, P = 0. 027), but was not significantly correlated with lymphocyte subsets and CD4/CD8 ratio. Conclusions Zinc deficiency is common among patients with CAPD. Adequate dietary zinc intake can facilitate protein synthesis and improve the overall nutritional status. High serum zinc concentrations are beneficial for the synthesis of hemoglobin and the improvement of anemia.

Objective To investigate the relationship between plasma albumin and hemoglobin(Hb) levels and prognosis in patients with severe craniocerebral trauma. Methods The clinical data of 124 patients with severe craniocerebral trauma form January 2010 to January 2014 were analyzed retrospectively. The relationship between plasma albumin and Hb levels and prognosis were analyzed. Hb level was obtained in 3 days of admission, and then the patients were divided into Hb <90 g/L group, Hb 90-99 g/L group, Hb 100-110 g/L group, Hb >110 g/L group, and also were albumin <25 g/L group, albumin 25-28 g/L, albumin 29-31 g/L group, albumin>31 g/L group according to the mean albumin level. Multifactor Logistic regression analysis was used to analyze the relationship between Hb, albumin levels and prognosis. Results Among 124 patients, 37 patients (29.8%) were given red blood cell (RBC) transfusion, and 28 patients (22.6%) received albumin treatment. The hospital mortality was 20.2% (25/124). The age, scores of Glasgow Coma Scale (GCS) and Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ ), and hospital mortality in different Hb level groups had no significant differences (P>0.05). The age, scores of GCS score and APACHEⅡ score in different albumin level groups had no significant differences (P>0.05), but the hospital mortality in different albumin level groups had significant difference: 31.2%(10/32), 24.2%(8/33), 9.7%(3/31), 14.3%(4/28), P<0.05. Multifactor Logistic regression analysis showed that albumin level was the relevant factor for the severe craniocerebral trauma (P<0.01), the hospital mortality was decreased with the rising of the albumin level, but the risk of death was higher in albumin>31 g/L group than that in albumin 29-31 g/L group. Conclusions 29-31 g/L albumin level is the best for severe craniocerebral trauma patients. There is no significant impact of Hb on the prognosis for severe craniocerebral trauma patients.

Objective To investigate the effects of nasojejunal feeding plus nasogastric tube decompression in severe hypertensive intracerebral hemorrhage complicated with gastroparesis.Methods Fifty-six cases of severe hypertensive intracerebral hemorrhage complicated with gastroparesis admitted to hospital from January 2011 to June 2014 were chosen as study group, while the 52 cases of similar patients admitted to hospital from January 2007 to December 2010 were chosen as control group.Nasojejunal feeding and nasogastric tube decompression were given to the study group.Nasogastric enteral nutrition support therapy was firstly given to the control group conventionally,after 15 days if they still could to be tolerant of the enteral nutrition,then parenteral nutrition therapy were adopted.The weight, serum albumin, prealbumin and hemoglobin circumstances of the two groups were determined and the complications were recorded.The patients were followed up according to activity of daily liying(ADL) after 3 months.Results There was no significant difference on the average body weigh between two groups before treatment.The average body weight of the study group was significantly higher than that of the control group after 4 weeks treatment((57.2±5.3) kg vs.(52.8±4.9) kg,t=4.33,P＜0.01).The serum albumin, pre albumin and hemoglobin of 3 week, four week after treatment were significantly higher than those of the control group(serum albumin of 3 week: (34.5±3.3) g/L vs.(30.7±3.1) g/L;erum albumin of four week:(37.8±3.8) g/L vs.(34.1 ± 3.4) g/L;serum prealbumin of 3 week:(202.3± 16.7) g/L vs.(179.6 ±15.2) g/L;serum prealbumin of four week: (216.9±17.1) g/L vs.(203.1±15.4) g/L;hemoglobin of 3 week : (119.4± 12.1) g/L vs.(107.7 ± 11.3) g/L;hemoglobin of four week : (126.2± 12.8) g/L vs.(113.5 ±11.9) g/L).Nutritional status of study group was significantly better than that of the control group(t=6.16, 5.32,7.37,4.85,5.18,5.32;P＜0.01), and complications was significantly less than that of the control group (P＜0.05).After three months, the good prognosis rate of study group (80.36％ (45/56)) was significantly higher than that of the control group (6 1.54％ (32/52)), the difference was statistically significant (x2 =4.67, P ＜0.05).Conclusion Nasojejunal feeding plus nasogastric tube decompression for patients with severe hypertensive intracerebral hemorrhage with gastroparesis can improve nutritional status, enhance their body resistance, reduce the incidence of complications, and improve their prognosis.

Objective To investigate the biosynthesis of arbutin by suspension culture of crown gall of transgenic Panax quinquefolium. Methods Hydroquinone in methanol(60 mg/mL) was added to the medium of the crown gall of P.quinquefolium after precultured for 20 d,then they were co-cultured for another 60 h.The product was isolated and purified by column chromatography and its structure was identified by physicochemical properties and spectroscopic data.The dynamic curve of biotransformation was investigated by quantative analysis of arbutin with HPLC.Results The product could be obtained from both of the culture and medium,which was isolated and elucidated as 4-hydroxyphenyl-?-D-glucopyranoside(arbutin).After co-cultured for 60 h,the mole conversion ratio of hydroquinone is 88.4%,the product contents in culture and medium are 63.69 mg/flask and 1.86 mg/flask,respectively,and the excretion ratio of arbutin reaches the highest(2.92%).Conclusion It's the first time around the world that the crown gall of transgenic P.quinquefolium is used as a biotransformation system and arbutin which shows varied pharmacological activites have been got successfully.

Objective To sum up the clinical characteristics and the diagnostic and therapeutic principle of severe hypertensive intracerebral hemorrhage complicated with gastroparesis.Methods The clinical data of 51 patients with severe hypertensive intracerebral hemorrhage complicated with gastroparesis were retrospectively analyzed.Results Of the patients who died,3 died of over-severe hemorrhage,and 1 died of acute respiratory distress syndrome caused by aspiration,as well as one died of respiratory failure resulting from pulmonary infection after aspiration.None died of digestive tract complication.Twenty-one patients(41.18％) needed feeding via naso-intestinal tube.Thirty patients (58.82％) were recovered within two weeks and 14 patients (27.45％) were recovered within the third week,and those who recovered beyond three weeks accounted for 3.92％ (n =2).Conclusion The gastroparesis complicating severe hypertensive intracerebral hemorrhage is considered as a functional disorder rather than mechanical obstruction.It is mainly on the basis of symptoms and signs in combination with gastroscopy or radiography that the diagnosis can be made.The conservative treatment (including nasal feeding in some patients) should be applied to the disorder.
