Objective To investigate the expression and clinical significance of tumor-associated carbohydrate anti-gen sTn in endometrium from patients with atypical hyperplasia of endometrium, endometrial carcinoma and benign the uter-ine lesion. And to analyze the association between sTn and the pathologic stage and grade of endometrial carcinoma. Meth-ods sTn was detected by immunohistochemistry in 193 patient samples, including 93 subjects with endometrial carcinoma, 50 subjects with atypical hyperplasia of endometrium and 50 subjects with benign uterine lesions. Results The positive sTn rate in endometrial carcinoma group was 73.1%,which was significantly different from that in atypical hyperplasia endo-metrium group (32%) and that in benign uterine lesion group (14%), (P＜0.017). sTn positive rate in patients with endometri-al carcinoma was 78.8%which is higher than that in patients with other diseases (P＜0.008 ). The positive rate of sTn in pa-tients with poorly differentiated endometrial carcinoma was significantly higher than that in patients with highly differentiat-ed endometrial carcinoma (P＜0.017). The positive rate of sTn in tissues of tumor infiltration with depth of more than half of myometrial was significantly higher than in tissues of tumor infiltration with depth of equal or less than half of myometrial (P＜0.05). But there was no significant difference in sTn positive rate between the endometrial carcinoma groups with and without lymph node metastasis (P>0.05). Conclusion sTn may play a role in the tumorigenesis and development of endo-metrial carcinoma.

Objective:To observe the clinical efficacy of point application with Da Huang (Rhizoma Rhei Cruda) powder at Shenque (CV 8) plus moxa-salt hot compress on the umbilicus for preventing gastrointestinal adverse reactions after chemotherapy for non-Hodgkin lymphoma (NHL).Methods:A total of 60 cases with NHL under chemotherapy were divided into two groups by hospitalization order,with 30 cases in each group.The control group was treated with routine nursing and the observation group was additionally given point application with Da Huang (Rhizoma Rhei Cruda) powder plus moxa-salt hot compress on the umbilicus,to compare the effect in preventing gastrointestinal adverse reactions after chemotherapy between the two groups.Results:The occurrence rates of constipation,nausea,vomiting and poor appetite on the second day and fifth day after chemotherapy were obviously lower in the observation group than those in the control group,with statistically significant differences between the two groups (all P＜0.05).Conclusion:The point application with Da Huang (Rhizoma Rhei Cruda) powder at Shenque (CV 8) plus maxa-salt hot compress on the umbilicus can produce more significant efficacy in preventing the gastrointestinal adverse reactions after chemotherapy for NHL than routine nursing.Moreover,it is simple and easy to be used and popularized.

ObjectiveThe purpose of this study is to discuss the diagnostic accuracy of nornalized liver ADC using the spleen and renal cortex as reference organs for the diagnosis of liver fibrosis.Methods Forty three patients with liver disease (chronic liver disease group) at compensated stage and 10 healthy volunteers (control group) were retrospectively assessed with diffusion-weighted imaging at a 3.0 T MR unit.Liver ADC,spleen ADC,renal ADC and normalized ADC (defined as the ratio of liver ADC to spleen ADC or renal cortex ADC,S-ADC and R-ADC for short) were measured in patients stratified by fibrosis stage.Spearman analysis was used to see the correlation between fibrosis stages and ADC,one-way ANOVA was used to compare the ADCs in different fibrosis stages.Logistic regression analysis was used to determine the performance of ADC for prediction of liver fibrosis,and show the area under the curve ( AUC),sensitivity and specificity choosing the optimal cutoff value that maximized the Youden index.ResultsTen volunteers belonged to SO stage.From SO to S4 stage,there were 2,5,9,12 and 15 patients,correspondingly,liver ADCwere (1.37±0.13) ×10-3,(1.33±0.16) ×10 -3,(1.17±0.16) ×10-3,(1.23±0.14) ×10-3and ( 1.12 ±0.11 ) × 10-3mm2/s,S-ADC were 1.86 ±0.18,1.68 ±0.12,1.34 ±0.14,1.48 ±0.15 and 1.34±0.10,R-ADC were 0.71 ±0.08,0.68 ±0.12,0.61 ±0.09,0.64 ±0.11 and 0.60 ±0.08respectively,and the differences among them were significant ( F =6.48,18.70 and 3.04,P ＜0.05 ).The correlation between fibrosis stage and S-ADC was stronger than between fibrosis stage and liver ADC,R-ADC (r =- 0.71,- 0.51,- 0.41 ;P ＜ 0.01 ).S-ADC was superior to liver ADC and R-ADC for detection of S2,S3 and S4 fibrosis stage (Youden index:0.91,0.58,and 0.59).ConclusionSpleen normalized liver ADC improves diagnostic accuracy for detection of liver fibrosis than liver ADC and renal normalized liver ADC.

Background Curcumin can eliminate free radical arising in the system and superoxide anion and further inhibit lipid peroxidation.Researches proved that curcumin has resisting effect on oxidative damage of lens,but its effect on the formation of age-related cataract is under clear.Objective This study was to investigate the effect of curcumin on the cataract induced by sodium selenite.Methods Thirty healthy clean SD rats of 12-day-old were selected.All the rats were randomly divided into the normal control group,model group and curcumin group and ten rats for every group.The selenite cataract models were established in the rats of model group and curcumin group by the injection of sodium selenite subcutaneously.Meanwhile,0.005 ％ curcumin lavaged the rats in the curcumin group daily for two weeks.Lens of the rats were examined under the slit lamp at 4,7,10,14 days after injection in all groups,and the opacification of lens was graded based on the He' criteria.The lenses of rats were obtained at the end of experiment and then the level of superoxide dismutase (SOD),the activities of malondialdehyde (MDA) and glutathione peroxidase(GSH-Px) in rat lens were detected using biochemical assay method.The use of experimental animals followed the Regulations for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission.Results The lenses were transparent throughout the experimental duration in the blank control group.Compared with model group,the development of the Ⅲ,Ⅳ,Ⅴ grade of cataract was slow down in the curcumin group with the significant difference( P＜0.05 ).The content of MDA,SOD and GSH-Px activity in lens appeared considerable differences among 3 groups ( MDA:F =215.42,P＜0.01 ; SOD:F =46.83,P＜ 0.01 ; GSH-Px:F=44.29,P＜0.01 ).The level of SOD was significantly reduced in the model group and the curcumin group compered with blank control group ( P ＜ 0.05 ) and that in the curcumin group was higher than the model group ( P＜0.05 ).The MDA level in the model group and the curcumin group was obviously rised in comparison with blank control group( P＜0.05 ),but that in the curcumin group lowed in comparison to model group( P＜0.05 ).GSH-Px activity in the curcumin group was significantly lower than that in blank control group and higher than that in the model group( P ＜ 0.05 ).Conclusions The curcumin can effectively delay rather than the cataract formation induced by sodium selenite in SD rat by improved the resistance of oxidation in the lens.

Purpose To investigate the expression of the protein of CD151 and MT1-MMP in adenocarcinoma of esophagogastric junc-tion tissues and to explore their relationship with the invasiveness and metastasis of the tumor. Methods CD151 and MT1-MMP pro-tein were detected by immunohistochemical staining respectively in 15 cases of paraneoplastic normal gastric mucosa tissue, 40 cases dysplasia and 172 cases of adenocarcinoma of esophagogastric junction tissues. Results All of the expression level of CD151 and MT1-MMP protein were increasing according to the order of normal-dysplsia-carcinoma. The expression rate of CD151 was 6. 67%, 20. 0% and 78. 3%, while the rate of MT1-MMP with 13. 3%, 22. 5% and 79. 1% in the normal, dysplasia and carcinoma subgroup. The expression rate of each protein were significant difference among the three goroups (P<0. 05). In the adenocarcinoma of esopha-gogastric junction tissues, the expression of them in the subgroup of poorly-differentiated with serosa invasion and lymph nodes metasta-sis was significantly higher than the other subgroup of well-differentiated with non serosa invasion or lymph nodes metastasis ( P <0. 05 ) . There was a positive correlation between the expression of CD151 and MT1-MMP protein in adenocarcinoma of esophagogastric junction tissues ( P<0. 05 ) . Conclusions CD151 and MT1-MMP assuredly and highly express in the adenocarcinoma of esopha-gogastric junction tissues and they have close relationships, which could involved in the invasiveness and metastasis synergistically in this tumor.

Objective Heart transplantation is an effective treatment of end-stage heart diseases and extending the time of donor heart preservation helps to make up for the shortage of donor hearts. This study was to investigate whether high-pressured mixed gas ( HPMG) of carbon monoxide and oxygen could prolong the time of donor heart preservation and its mechanisms. Methods Forty-eight C57BL/6 male mice aged 4-6 weeks were randomly divided in-to four groups of equal number:control ( the donor heart isolated but not transplanted) , immediate transplantation ( the donor heart transplanted right after isolated) , HTK-preservation ( the donor heart preserved in histidine-tryptophan-ketoglutarate solution for 24 hours after isolated, and HPMG preservation ( the donor heart preserved in an HPMG chamber with the oxygen partial pressure of 3200 hPa and carbon monoxide partial pressure of 800 hPa for 24 hours after isolated) .Another 36 recipient mice aged 6-8 weeks were randomly assigned to receive the donor heart immediately after harvested (n=12), preserved in HTK solution (n=12), or preserved in HPMG (n=12).At 2 hours after transplantation, the status of heart re-beating and cardiac function were compared among different groups of recipient mice.At 24 hours, tissues were taken from the transplanted hearts for examination of pathologic changes by HE stai-ning, detection of the apoptosis of cardiac cells by TUNEL, and determination of the expressions of microtubule-associated protein 1 light chain 3 -Ⅱ(LC3-Ⅱ) and B cell lymphoma/leukemia-2 (Bcl-2) by Western blot. Resul ts The re-beating rates of the imme-diately transplanted and HPMG-preserved hearts were significantly higher than that of the HTK-preserved ones (P<0.05).At 2 hours after transplantation, the cardiac function scores were 2.5 (2.0-2.9), 0.8 (0.5-1.0), and 4.5 (4.0-4.5) in the immediate implantation, HPMG-preservation and HTK-preservation groups respectively, with statistically significant differences between any two groups (P<0.05).The expressions of LC3-Ⅱand Bcl-2 were 2.06 ±0.29 and 0.87 ±0.18 in the HPMG-preserved heart recipients and 1.24 ±0.20 and 2.07 ±0.32 in the immediately transplanted heart recipients, both higher than 0.13 ±0.03 and 0.19 ±0.02 in the controls and 0.16 ±0.06 and 0.26 ±0.08 in the HTK-preserved heart recipients (P<0.05), the Bcl-2 higher in the HTK-pre-served heart recipients than in the controls (P<0.05), and the LC3-Ⅱ expression higher in the HPMG-preserved heart recipients than in the immediately transplanted heart recipients (P<0.05).HE staining showed that cell edema and inflammatory cell infiltration were more obvious in the HPMG-preserved heart recipients than in the controls and immediately transplanted heart recipients but less obvious than in the HTK-preserved heart recipients.The rate of cell apoptosis was dramatically increased in the HPMG-and HTK-pre-served heart recipients ([5.04 ±1.77]%and [26.72 ±5.23]%) in comparison with the controls ([1.08 ±0.56]%) (P<0.01) and immediately transplanted heart recipients ([2.13 ±1.71]%) (P<0.01) but decreased in the HPMG as compared with the HTK-preserved heart recipients (P<0.01). Conclusion High-pressured mixed gas preservation can reduce cold ischemia-reperfu-sion injury of the donor heart, which may be associated with its promotion of autophagy, provision of energy to cells, and apoptosis of cardiocytes in the donor heart.
