Tianjin Medical Journal 2010;38(3):207-208,后插1
Objective:To detect the expression of vascular endothelial growth factor receptor-3(VEGFR-3)in earlystage tongue cancer and the relationship with occult metastasis thereof.Methods:The expression of VEGFR-3 was examined in paraffin-embedded specimens from 62 patients with early-stage tongue cancer by immunohistochemical staining.The relationship was analyzed between the expression of VEGFR-3 and size,occult metastasis and differentiation of early-stage tongue cancer.Results:The positive expression of VEGFR-3 mainly located in the lymphatic endothelial cells of peritumoral areas and negative expression in tumor area.The higher expression of VEGFR-3 was found in patients with occult metastasis.The expression of VEGFR-3 was significantly higher in patients of Ⅱ-Ⅲ grade than that of patients in I grade carcinoma(t=4.77,P < 0.05).The expression of VEGFR-3 was higher in patients with occult metastasis than that in patients with negative lymph node(t=6.33,P < 0.05).But there were no significant correlation between the expression of VEGFR-3 and the age,gender and size of tumor in patients.Conclusion:The value of VEGFR-3 can be a useful indicator to evaluate the occult metastasis of early-stage tongue cancer.

Objective: To study La accumulation and microstructure change of leg bones of rats fed with La(NO 3) 3 in low dosage for a long term. Methods: After the rats were fed by La(NO 3) 3 in dosage of 2 mg?kg -1 ?d -1 for 6 months, the contents of La and Ca,P in the leg bones were determined by ICP MS and spectrophotometry; the microstructure changes of the leg bones were investigated by electron microscopy and X ray powder diffraction. Results: In the leg bones of tested rats, the contents of La and P increased greatly, and those of Ca did not change obviously, so that Ca/P ratio values decreased in comparison with the control group. Conclusion: La was accumulatied in the rat leg bones and the change of bone microstructure induced after the rats were fed with La(NO 3) 3 in low dosage for a long term.

OBJECTIVE:To investigate the effect and cost of Multidimensional iron oral liquid and Polysaccharide iron com-plex capsules in the treatment of iron deficiency anemia during pregnancy. METHODS:By retrospective study,80 cases of iron de-ficiency anemia during pregnancy were divided into control group and trial group in accordance to different therapy plans,with 40 cases in each group. Control group was given Multidimensional iron oral liquid orally,10 ml each time,bid,after breakfast and supper,for consecutive 4 weeks;trial group was given Polysaccharide iron complex capsules orally,0.30 g each time,qd,for con-secutive 4 weeks. Clinical efficacy,erythrocyte related lab indexes,satisfactory rate and ADR were compared between 2 groups, and cost-effectiveness analysis was adopted for economic evaluation. RESULTS:The total effective rate of experimental group was 95.0%,which was higher than 85.0% of control group,but without statistical significance(P>0.05);hemoglobin level,erythro-cyte count and average volume of erythrocyte of trial group were significantly higher or more than control group,and satisfactory rate(95.0% vs. 65.0%)were significantly higher than control group,with statistical significance(P<0.05);no obvious ADR was found in 2 groups. Total cost of trial group and control group were 243.60 and 166.32 yuan,and cost-effective ratio was 2.56 and 1.96;incremental cost-effective ratio was 7.73. Results of sensitivity analysis were same to the result. CONCLUSIONS:Both Multi-dimensional iron oral liquid and Polysaccharide iron complex capsules can improve anemia in patients with iron deficiency anemia during pregnancy. Polysaccharide iron complex capsules show better therapeutic efficacy and satisfactory rate,but it is relatively ex-pensive. Drugs should be selected according to economic situation.

Objective: To establish the method for determination of taurocholic acid in the Traditional Chinese Medicine Shedanchuanbei Oral Liquid and snake bile. Methods: The sample was prepared as mixed solution containing methanol and KH 2PO 4. The mixed solution was injected into Sep Pak C 18 cartridge for the purpose of sample purity. In this processing, the substances which having strong retain action and could harm analytic column were hold in the Sep Pak C 18 cartridge. The eluting solution that the Sep Pak C 18 cartridge had be over loading for taurocholic acid was used as the test solution. The test solution was measured by RP HPLC. The chromatographic conditions were as followed: Supelcosil LC 8 column(150mm?4.6nm,5?m) as analytic column, detect wavelength at 203nm, and MeOH 0.4%KH 2PO 4 mixed solution(56∶44, V/V ) as mobile phase. The inject volume was 50?L. Results: The linear response range of sodium taurocholate was from 0.0253mg?mL -1 to 0.253mg?mL -1 , and the correlation coefficient was 0.9999. The average recovery rate was 101.3%, RSD was 0.40%( n =6). Conclusion: This method was simple, efficient and suitable to the quality control for Shedanchuanbei Oral Liquid and snake bile.

Bonetumorisonekindofmalignanttumorwhichthreatslifeamongchildrenandadoles-cent.Osteosarcoma (OS ) and Ewing sarcoma (ES ) have been paid much attention by medical community because of their complex occurrence,development,metastasis mechanism and poor prognosis.The research showed that activation of protooncogene and mutation of suppressor gene,absence of apoptosis signal and hypox-ia-inducible factor (HIF)all participated in the occurrence,development and metastasis of OS and ES.It is suggested that clarified pathomechanism of bone tumors could provide more effective therapeutic strategies and lower the mortality of patients.

Objective To explore the roles of biomarkers of the ratios of microRNA (miRNA)in osteosarcoma.Methods The blood samples from 20 patients with osteosarcoma and 30 healthy people with similar age were choosed.The miRNA expression profiles were filtered by gene chips of high flux.The results were verified by qRT-PCR.The miRNA expression ratio was analysed by receiver operating characteristic (ROC)curve aiming to find the most predictive potential combination-type markers.Results Two hundred and fifty-eight miRNAs were found to be significantly deregulated in blood samples from 30 patients with osteo-sarcoma as compared with their matching normal blood samples (F=5.564,P<0.05).Four miRNAs were choosed from blood samples of22 patients with osteosarcoma and normal blood samples.MiR-181b,miR-199b-5p and miR-451 were significantly higher than that in normal blood sample (F=6.283,P<0.05),while miR-124 showed low expression (F=7.201,P<0.05).Furthermore,the ratio of miR-199b-5p/miR-124 showed a high sensitivity (96%)and specificity (97%).Conclusion The abnormal expression of miRNA in osteosar-coma makes it have a predictive effect.The ratio of miR-199b-5p/miR-124 could be served as combination-type biomarkers in the diagnosis of osteosarcoma.

Objective To investigate the expression of PHF8(PHD-finger protein 8) in human hepatocellular carcinoma (HCC) and its clinicopathologic significance.Methods The expression of PHF8 in 60 hepatocellular carcinoma samples as well as their natched paraneoplastic tissues,and 15 normal liver tissues were evaluated by immunohistochemistry.Statistical methods were used to analyse the relationship between the expression of PHF8 and the clinicopathological features of these patients.Results The PHF8-positive expression rate in the HCC samples was 55.0% and it was significantly higher than that in the paraneoplastic tissues and the normal liver tissucs (16.7%,6.7%,respectively,P<0.05).The expression of PHF8 was closely related to tumor size,tumor nodular numbers,pathological differentiation and TNM-staging (P<0.05 for all).The 5-year disease-free survival and overall survival in the PHF8-positive group was significantly lower than that in the negative group (P<0.05).Conclusions PHF8 was overexpressed in HCC samples,and its expression was closely associated with HCC clinicopathological features and prognosis of the patients.
