Nutrition Risk Screening 2002 (NRS 2002) was developed on the basis of 128 randomized controlled clinical studies by a group of experts led by Kondrup from the European Society for Parenteral and Enteral Nutrition (ESPEN).As the first evidence-based nutritional screening tool worldwide,NRS 2002 has been recommended for nutritional risk assessment of hospitalized patients in Europe for the addition of disease metabolism and its simplicity.In this article,we reviewed the increasing applications of NRS 2002 in China,pointed out the existing problems and made several suggestions on improvement for popularization and standardization of its clinical use.

Objective To explore the clinical characteristics,pathological features,therapy and prognosis of a case of splenic marginal zone lymphoma (SMZL) with central recurrence,evaluation the safety and efficacy of rituximab intrathecal injection combined with intravenous chemotherapy.Methods Retrospectively analyze the case of SMZL with the central recurrence,and review the relevant literatures.Results According to the tests of MICM of bone marrow,spleen pathology,PET-CT and laboratory examination (LDH),patient was diagnosed as SMZL,IV group B,IPI and aaIPI was high risk group.After first-line therapy,the patient achieved complete remission.But then the central nervous system relapsed.The patients was treated with rituximab intrathecal injection combined with intravenous chemotherapy,the central focus disappeared.Conclusion SMZL belongs to low-grade lymphoma,which combined with central nervous system relapse is very rare.Rituximab intrathecal injection combined with intravenous chemotherapy in the treatment of the patients is safe to use,and have good clinical efficacy.

Objective To evaluate the results and toxic effects in three dimensional radiotherapy (3DCRT)with late course accelerated hyper-fractionation for advanced esophageal carcinoma.Methods From December 2001 to December 2003,115 patients were randomly divided into two groups:in 3DCRT group,55 patients were given late course accelerated hyper-fractionation radiotherapy to a total close of 66 Gy (2.0 Gy per fraction,5 times per week;to a dose of 36 Gy were changed into 1.5 Gy/f,2 f/d).In CF group,60 patients were given late course accelerated hyper-fractionation radiotherapy to a total dose of 66 Gy.Results The 1-, 2-,3-,4-year survival rates in 3DCRT group were 63.6 %, 50.9 %, 38.2 %, 30.9 % compared to 58.3 %, 38.3 %,33.3 %,23.3 % in CF group(X~2=4.44,P=0.031),and local control rates in 1-,2-,3-,and 4- years in 3DCRT group were 72.7 %,58.1%,47.2 % and 36.3 %,compared to 53.3 %,40 %,28.3 %,and 20 %(X~2=5.33,P=0.013)in CF group.However,in the 3DCRT group,the incidence of acute esophagitis was similar to CF group; hematogenous toxic and acute bronchitis were similar between the two groups. Late course lung injury in CF group was higher than that in 3DCRT group.Conclusion 3DCRT is able to improve the local control rate and survival rate,and unable to improve acute and late radiation toxie effects.

Objective:To obtain AP2/ERF genes from Brassica oleracea by using in silico cloning. Methods: AP2/ERF genes were cloned by retnieving the EST database and using the bioinformatics software with the Arabidopsis thaliana AP2/ERF as a querying probe. Results:Two AP2/ERF family transcriptional regulators (BoAP2/ERF1 and BoAP2/ERF2) were isolated from Brassica olera-cea by the in silico cloning method. Some characters of AP2/ERF protein were analyzed and predicted by the tools of bioinformatics in the following aspects including the composition of amino acid sequence, hydrophilicity and hydrophobicity, subcellular localization, secondary and tertiary structure of protein and function. Conclusion:Bioinformatical analysis shows BoAP2/ERF1 and BoAP2/ERF2 gene encode 40. 85kDa and 39. 44kDa protein with 371 and 352 amino acids. The domain is predicted to locate on nucleus. Sequence analysis indicates the protein may be involved in signaling transducer and stressing response roles in plantbiotic stresses.

Objective To study the rational daily administration times of Yinchenhao Decoction (YCHD) when it was used to treat experimental jaundice in rats based on pharmacodynamics/pharmacokinetics model.MethodsRats were modeled by 4％ 1-naphthylisothiocyanate (75 mg/kg) for 48 h,then YCHD was drenched with doses of 0.324 g/kg (extract,calculated with the clinical dosage) once,0.162 g/kg twice,and 0.108 g/kg thrice a day,respectively.The total bile and the flow rate of bile were observed after the first administration; Blood samples collected from the orbital sinus at different intervals were used to investigate the levels of liver enzymes (ALT and AST) and bilimbins (TBIL and DBIL),and determine the concentration of 6,7-dimethoxycoumarin (DME) in the plasma using UPLC at the same time,then we obtained the time-effect and time-dose curves.The rational daily administration times of YCHD when treating experimental jaundice were determined based on the comprehensive analysis of time-effect and time-concentration relationships.ResultsWithin 10 h the total bile of rats which were administered once daily (G1) was I.65 and 1.33 times higher than that of twice and thrice (G2 and G3) a day,respectively,and the four biochemical indexes (TBIL,ALT,DBIL,and AST) of Gl decreased faster than those of G2 and G3 (P ＜ 0.05).On the other hand,the blood drug level of DME when administrated once daily could maintain at a higher level for a longer time,and its Cmax and AUC0→t were higher than those of G2 and G3,which might be the main reason why its effect was the most significant.ConclusionIt is more appropriate to administrate once daily when YCHD is used to treat jaundice.

Objective To observe the effects of static pressure on the number of cultured retinal M?ller glial cells(RMGC)and expression of glial fibrillary acidic protein(GFAP)and heat shock protein(HSP)70 by these cells.Design Experimental study. Participants Cultured rat RMGC.Methods Rat RMGCs were cultured and identified according to previous method described by Reichenbach.These cells were treated with different static pressures and divided into 4 groups:A(1.33kPa),B(2.67kPa),C(5.33kPa)and D(10.67 kPa)while the cells without treatment was as control group(NC).The morphologies of RMGC in these groups were observed under inverted phased contrast microscope,the number of RMGC counted with conservative method and the viability were studied with trypan blue staining.The expressions of GFAP and HSP70 in RMGCs were detected with the method of western blot.Main Outcome Measures The morphologies of RMGC,cell number,cell viability.Results There were pressure-dependent changes of RMGC number. The cell number of group C and D was less than that of group NC,A and B(P＜0.01).High static pressure resulted directly in the decreased ratio of unstained RMGCs(P＜0.01).The ratio of unstained RMGCs in group C and D was less than that in group NC,A and B(P＜0.01).Many cells in group C and D were injured and the higher the pressure elevated,the more the degree of injury became.The expressions of GFAP and HSP70 in group NC were less than other pressure treated groups and the expression of GFAP in group C and D was higher than that in group A and B.There was no obvious difference between these pressure treated groups.Conclusions High static pressure could cause the injuries of RMGCs.The increased expression of GFAP and HSP70 in RMGC might be regarded as a sign of retinal injury response to high intraocular pressure.
