Two dietary protein levels, the marginal level (8%) and the normal level (20%), were employed in the present experiment to test their effects on the nutritional status, cellular immunity and immunostimulating action of argin-ine in the mice inflicted with 13% BSA, full thickness burn. The postburn changes of nutritional status were influenced noticeably by the dietary protein level. When the traumatized mice were fed with the ration containing 8% protein, the number of peripheral blood ANAE+ lymphocytes fell significantly and the irnmunostimulatory action of arginine was also markedly depressed. The probable reasons were discussed.

Objective To study treatment effect of qingre shugan tuihuang tang in the treatment of newly diagnosed hepatitis B with jaundice.Methods88 patients newly diagnosed hepatitis B with jaundice in our hospital from August 2015 to December 2016 were randomly divided into control group and treatment group according to different modes of treatment, control group was given protecting liver and reducing enzyme, antivirus and other conventional therapy, treatment group added qingre shugan tuihuang tang on the basis of control group, changes of liver function indexes, changes of bilirubin, changes of clinical syndromes and treatment effect in the two groups were compared.ResultsSerum total bilirubin (TBIL), direct bilirubin (DBIL), Alanine transaminase (ALT) and prothrombin time (PT) in the two groups were significantly decreased (P<0.05), albumin was significantly increased (P<0.05), and rangeability of TBIL, DBIL, ALT and albumin in treatment group after the treatment were significantly higher than control group, the difference was statistically significant (P<0.05);hepatitis B virus DNA copy numbers in the two groups were significantly decreased (P<0.05), treatment group was significantly lower than control group, the difference was statistically significant (P<0.05);yellow tint of sclera and skin, gastric distention, rib-side pain, anorexia, drowsiness and fatigue symptom scores in the two groups were significantly decreased (P<0.05), decrease of treatment group was significantly higher than control group, the difference was statistically significant (P<0.05);total effective rate of treatment group was 97.73%, while the control group was 81.82%, the two groups had significant difference (P<0.05).ConclusionQingre shugan tuihuang tang in the treatment of newly diagnosed hepatitis B with jaundice can improve symptoms of jaundice significantly, improve liver function injury, effect is remarkable, its clinical application is very important.

Objective:To discuss treatment of complete response cases after neoadjuvant radiotherapy in rectal cancer. Methods:This retrospective study analyzed clinical data of 84 rectal cancer cases with pre-operative neoadjuvant chemoradiotherapy in our hospital from January 2010 to Augnst 2014. Results:After neoadjuvant chemoradiotherapy, 33 patients presented clinically complete response at a rate of 39.3%. After post-operative pathologic examination, among clinically complete response cases, six cases exhibited patho-logically complete responses at a rate of 18.2%. No recurrence or disease progression occurred within 12-36 months of post-operative follow up. Conclusion:Neoadjuvant chemoradiotherapy can significantly lower tumor stage and promote clinically complete remission of some patients. However, for clinically complete remission cases, further radical surgery should be provided.

Objective: To study if the immune-enhancing effect of Arg was mediated via liver.Methods: The direct effect of Arg on T cell proliferation was measured by 3H-TdR incorporation. Rat hepatocytes were primarily cultured in serum-free DMEM/F12 medium, and then cultured in medium containing Arg(?mol/L:0,7.5,75,750,7 500), and the supernatant was collected at 0, 24, 48, 72 hours, and added to splenocytes culture, and T cell proliferation, NK cell activity and IL-2 activity,〔Ca 2+〕i were measured respectively.Results: Arg had no direct effect on splenocyte proliferation. The hepatocyte culture supernatant significantly increased the lymphocyte〔Ca 2+〕i ,IL-2 activity and T lymphocyte proliferation; 7 500 ?mol/L was most effective. Conclusion: Arg may enhance immune function via secretion of bioactive molecules by hepatocytes.

AIM: To investigate the antagonistic effect of zinc on hepatic ischemia- reperfusion (HIR) injury and the effect of zinc on the expression of adhesion molecules in rat liver to clarify the mechanisms involved. METHODS: After zinc supplementation (5 ?mol/kg bw,po) , the changes in hepatocellular morphology,ALT and AST activities in serum,MDA levels in serum,and expression of ICAM-1,VCAM-1 in liver of the animals subjected to HIR were examined. RESULTS: The results showed that HIR (30 minutes of ischemia followed by 90 minutes of reperfusion) significantly increased ALT, AST activities and MDA levels in serum. The destruction of hepatic structure was observed in HIR rats. In the mean time, the expression of adhesion molecule was enhanced.After zinc administration, ALT and AST activities in serum and MDA levels in serum were all decreased. The structure of hepatocyte was nearly normal.The further experiment showed that adhesion molecule expression was suppressed.CONCLUSION: These results indicate that zinc may protect liver against ischemia-reperfusion injury by inhibiting the production of free radicals and the expression of adhesion molecule.

Objective To analyze the flavonoid content of common fruits consumed in China.Method Thirty-eight fruits were sampled from Beijing,Tianjin,Shanghai and Hangzhou.The contents of quercetin,kaempferol,luteolin,myricetin,apigenin were determined with high-performance liquid chromatography.Results Pomegranate and hawthorn were the highest in contents of 5 flavonoids among 38 fruits.Quercetin distributed more widely and was more abundant than other flavonoids in fruits.The daily intake of 5 flavonoids from fruits by Chinese people was estimated to be 2.80 mg.Conclusion The content of flavonoids varies significantly among different fruits and quercetin is the most common flavonoid contained in fruits.

Objective To analyze the flavonoid content of common vegetables consumed in China.Method Forty-six vegetables were sampled from Beijing,Tianjin,Shanghai and Hangzhou.The contents of quercetin,kaempferol,luteolin,myricetin,apigenin were determined with high-performance liquid chromatography.Results Mei celery sampled from Hangzhou was the highest in content of 5 flavonoids among 46 vegetables.Quercetin distributed more widely and was more abundant than other flavonoids in vegetables.The daily intake of 5 flavonoids from vegetables by Chinese people was estimated to be 13.90 mg,in which quercetin accounted for 51.1%.Conclusion The content of flavonoids varies significantly among different vegetables and quercetin is the most common flavonoid contained in vegetables.The dietary intake of flavonoids was more from vegetables than fruits in Chinese people.
