Quantitative calibration strategy as an essential issue in laser ablation ICP-MS plays an important role for the guarantee of analytical accuracy.In this study, uncertainties of reference values in current available glass certified reference materials (NIST, MPI-DING and USGS) as well as the matrix effect among them were systematically evaluated.The results illustrated that NIST610 was better than other reference materials from aspect of reference value uncertainty.The matrix effect among NIST, MPI-DING and USGS reference materials was insignificant under our experimental conditions.A quantification strategy based on two reference materials (NIST610 and StHs6/80-G) and normalization to 100% (w/w) was proposed to avoid the insufficiency of single reference material strategy, which suffered the very low content and large uncertainty for some elements.The comparision of ML3B-G results obtained from three quantification strategies (single reference material NIST610, single reference material StHs6/80-G and two refterence materials) illustrated that the proposed strategy improved the analytical accuracy.Three reference materials (BCR-2G, CGSG-2 and KL-2G) were quantified with the proposed strategy, and almost all data matched well with reference value, meanwhile the data reported here could supplement the reference value database.

OBJECTIVE:To observe the influence of capecitabine combined with radiotherapy on postoperative survival rate, relapse rate and survival quality of elderly patients with rectal cancer at Ⅱ-Ⅲ stage. METHODS:110 patients with rectal cancer atⅡ-Ⅲ stage were selected and randomly divided into control group and observation group with 55 cases in each group. Both group received radical resection of rectal carcinoma. Control group was given three dimensional conformal radiation therapy(3DCRT)af-ter operation;observation group was additionally given capecitabine 1 500 mg/m2,d1-14,qd,on the basis of control group. A treatment course lasted for 21 d,and both groups received 2 courses of treatment and followed up for 3 years. The survival rate and metastasis and recurrence rate of 2 groups were compared as well as KPS score before and after treatment. Toxic reaction of 2 groups was also observed. RESULTS:The follow-up total survival rate and disease-free survival rate of observation group were 89.09%and 76.36%,which were significantly higher than 74.55%and 54.55%of control group;the distant metastasis rate and lo-cal recurrence rate were 12.73% and 5.45%,which were significantly lower than 30.91% and 21.82%,with statistical significance (P<0.05). KPS score of 2 groups were increased significantly,between 2 groups before and after treatment ,with statistical signifi-cance(P<0.05);Comparison between groups(P>0.05). There was no statistical significance in the incidence of nausea and vom-iting,diarrhea and urinary tract reaction between 2 groups (P>0.05);but the incidence of bone marrow arrest in observation group was significantly higher than control group(P<0.05). CONCLUSIONS:Capecitabine combined with 3DCRT can effectively improve postoperative distant survival rate of patients with rectal cancer at Ⅱ-Ⅲ stage,and reduce the metastasis and recurrence risk;do not lower life quality and induce serious adverse reactions.

Objective To investigate the influence of Lipoprotein lipase (LPL)/Hepatic lipase (HL) on hyperlipidemie acute necrotizing pancreatitis (HLANP) in rats. Methods The rats were fed with hyperlipidemic feed for 4 weeks, then the rats were injected with 5% sodium taurocholate into pancreatic duct to induce HLANP model. Seventy-two rats were randomly assigned to HLANP and control groups, and then each group was subdivided into 6 subgroups (n = 6) at 0, 3, 6, 12, 24 and 48 h. Serum amylase, cholesterol, triglyeride (TG), free fatty acid (FFA) levels and serum LPL, HI. activities were determined. Under the light-microscopy and electron microscopy, the histopathologic and uhrastructure changes of pancreas were observed; the HL mRNA expressions were detected by RT-PCR; HL protein expressions HL were assessed by immunohistoehemical staining. Results The serum amylase levels reached peak values at 12 h after ANP induction in the two groups, the mean values were 7 176U/L and 6 366U/L, which were significantly higher than those of baseline values (P <0.05) ; serum levels of cholesterol in HLANP group at 0 ～ 12 h were higher than those of control group, however, only at 0 h the difference (1.19±0.49 vs 0. 32±0.14 mmol/L) was significant (P < 0.05) ; serum levels of FFA in HLANP group were not significantly different when compared with those of control group; serum levels of LPL and HL at 3 h were (17.5±7) U/L and (18.6±3.9) U/L, which were significantly higher than those of control group (8.9±3.4 U/L and 9.5±2. 1 U/L, P < 0.05). The pancreatic tissues necrosis levels were significantly increased in HLANP groups (3, 6, 24 and 48 h) than those of control group at corresponding time points (P < 0.05). lipid droplet deposition, rough endoplasmic reticulum distension, zymogen granule reduction, and chondriosome swelling in acinar cells of pancreatic tissues in HLANP group were found. The HI, mRNA expressions at 3 h and 6 h in HLANP group were 1.1±0.09 and 0.89±0.08, which were significantly higher than those in control group (0. 11 ± 0.01 and 0.15±0. 03, P <0.05). HL proteins were positively expressed in pancreatic tissues of two groups before ANP was induced, and HL proteins were strongly positively expressed after ANP induction. Conclusions Lipase (LPL/HL) expression increased in HLANP rats, and the content of serum protein increased, which resulted in lipids decomposition and increased the severity of ANP. LPL/HL may be one of the key lipids metabolic enzymes aggravating HLANP.

Objective To investigate the development and metastasis of malignant choroidal melanoma cell strain OCM-1-gfp modified with green fluorescent protein(GFP) and the factors which affected the tumor biological behaviors. Methods GFP was transfected into malignant melanoma cell strain OCM-1.Melanoma cells with high and stable expression of GFP were injected into subretinal space and the subcutaneous space of hind leg of Balb/c nude mouse respectively in order to establish orthotopic and heterotopic transplanted tumor models.The development and metastasis process of orthotopic tumor models was observed directly by fluorescence microscope,and the size of the hypodermal tumor was measured by vernier.The expressions of 13 genes in melanoma were detected by means of immunohistochemistry staining. Results Malignant choroidal melanoma cell strain OCM-1 stably expressed GFP and preserved the characteristics of parental generation,OCM-1-gfp may develop melanoma and continue to metastasize in nude mouse.Positive expression of most of the antibodies,including Rb,p53,p21,E_2F,NF?B,cyclin D1,proliferation cellular nuclear antigen(PCNA),bcl-2、bcl-XL/S,bax,and epithelial growth factor(EGF)and its receptor(EGFR),was found.While the staining of inhibition gene p16 was negative. Conclusions GFP is the marker for observing the development and metastasis of malignant choroidal melanoma in vivo.The rate of tumor formation and development process in orthotopic models does not differs much from which in heterotopic models of malignant choroidal melanoma.The expressions of lots of genes in malignant choroidal melanoma developed from OCM-1-gfp including p16、p53、NF?B,cyclin D,PCNA,EGF,and EGFR are abnormal.

Objective To investigate the expression and polymorphism of lipoprotein lipase (LPL) gene and their association with acute hyperlipidemic pancreatitis(HLP). Methods A total of 120 patients Were assigned to HLP group (n=20), acute pancreatitis (AP) group (n=50) and control group (n= 50). Serum levels of triglyceride (TG), cholesterol (Ch), free fatty acid (FFA), lipoprotein and apolipoprotein and serum LPL/HL activities were determined. The mRNA expressions of LPL/HL and LPL gene intron 8 polymorphisms were detected by RT-PCR and PCR-RFLP, respectively. Results The serum levels of TG, Ch, FFA and ApoE were significantly higher in HLP group than those in AP group and control group (P<0.05). The serum level of HDL was lower in HLP group than that in AP group and control group(P<0.05). The serum LPL/HL activities were significantly higher in HLP group than that in AP and control groups. The expression of LPL mRNA was up-regulated and intron 8 Hind Ⅲ H2 allele frequency was significantly inereased in the HLP group compared to control group(0.90/0.72, P<0.05). H1 allele frequency was significantly decreased in the HLP and AP groups compared to control group(0.10/0.28 and 0.14/0.28, respectively). Conclusions The high allele frequency of LPL gene intron 8 Hind H2 result in the increase of activities and expression of LPL mRNA, which exacerbate the development of HLP through changing TG metabolism such as FFA accumulation.
