Objective To explore the correlation between non-Hodgkin lymphoma (NHL) and hepatitis C virus (HCV) infection.Methods HCV infection of 208 NHL patients was investigated from the Affiliated Tumor Hospital of Zhengzhou University.Patients with leukemia or other tumors,and healthy people were used as the control and were pair matched on age and gender.ELISA method was used to detect the HCV-antibody in serum.Results HCV-antibody positive rate in NHL patients [11.5 ％ (24/208)] was significantly higher than those in leukemia patients [3.8 ％ (8/208)] (x2 =8.667,P =0.003),patients with other tumors (6/208,2.9 ％) (x2 =11.639,P =0.001) and healthy people [1.0 ％ (2/208)] (x2 =19.856,P =0.000).Conclusion HCV infection is related to NHL in Henan area.

Objective To explore the correlation of the gene polymorphism of the two single nucleotide polymorphisms(SNPs)rs1443434andrs925489onforkheadboxEl(FOXE1)withthehighnormalthyroidstimulating hormone ( TSH) level in Chinese Han population. Methods 1 400 subjects with normal serum TSH and thyroid peroxidase antibody(TPOAb) levels were included. According to TSH or TPOAb levels, the subjects were divided into high normal TSH group(H-TSH group,n=195) and normal TSH control group(TSH control group,n=1 205) or high normal TPOAb group ( H-TPOAb group, n=711 ) and low normal TPOAb group ( L-TPOAb group, n=689 ) , respectively. The genotypes on the two SNPs of all the subjects were performed by whole-genome genotyping chips. Results There were significant differences in rs925489 genotypic distributions and allele frequencies between H-TSH group and TSH control group(both P<0. 05). The genotype TT and allele T in H-TSH group were significantly higher than those in TSH control group(89. 75% vs 83. 15%, 94. 62% vs 91. 29%). The normal TSH levels were positively associated with rs925489 genotypic distributions after adjustment for sex, age, and high density lipoprotein cholesterol(P<0. 01). There were no significant differences in rs1443434 genotypic distributions and allele frequencies between two TSH groups or two TPOAb groups. Conclusion FOXE1 rs925489 gene polymorphism may be correlated with the high normal TSH level in Chinese Han population.

Aims To study single dose toxicity of poly-phenols effective parts from Punica granatum,to eval-uate their safety,and thus to provide a theoretical basis for drug development and clinical use.To observe their protective effect on ethanol-induced gastric ulcer in rats.Methods 50 healthy Kunming mice were ran-domly divided into five groups and given different doses of polyphenols’effective parts from Punica granatum via intragastric administration.Toxicity and death in each group of mice were observed and recorded after administration for 14 d.The median lethal dose was calculated by Bliss method.70 rats were randomly di-vided into normal group,model group(constant volume of normal saline),sanjiuweitai particles(1 850 mg· kg-1 )group,colloidal bismuth subcitrate (33 mg · kg-1 )group and polyphenols effective parts from Puni-ca granatum low-dose,medium-dose,high-dose(430, 852,1 704 mg·kg-1 )groups.On the 9th day of 10 days’gavage,all except the normal group were fed ethanol (1.5 mL/only)to induce gastric mucosal inju-ry in rats with acute gastric ulcer.Gastric ulcer index, the rate of ulcer inhibition were calculated for each group.The morphological changes of gastric mucosa were observed.The gastric mucosa levels of PGE2 , NO,SOD and MDA were determined.Results The LD50 and 95%confidence limit of the polyphenols’ef-fective parts from Punica granatum were 8 520.9 mg· kg-1 and 7 291.2 ~9 914.4 mg·kg-1,respectively. Pathology showed that the organs receiving dose of 16 000 mg · kg-1 had different degrees of damage . Compared with the model group,the extract from Puni-ca granatum significantly repaired the gastric mucosa, and significantly increased the gastric mucosa levels of NO and reduced MDA content,and improved SOD content and the levels of PGE2 .Conclousion The dose of 5 063 mg · kg-1 of polyphenols effective part from Punica granatum showed no death.The dose of 16 000 mg · kg-1 of polyphenols effective parts from Punica granatum could cause varying degrees of dam-age in heart,liver,lung,kidney or the death of mice. The LD50 and 95% confidence limit of the polyphenols effective parts from Punica granatum were 8 520.9 mg ·kg-1 and 7 291.2 ~9 914.4 mg·kg-1,respective-ly.The extract from Punica granatum plays a protective role against gastric mucosa damage induced by absolute ethanol,and the mechanism may be related to promo-ting ulcer epithelial cells synthesis,enhancing mucosal regeneration function,regulating NO content and en-hancing antioxidant capacity.

Objective To analyze the mammographic findings of ductal carcinoma in situ,and to improve DCIS diagnosis.Methods 1 58 cases of infiltrating ductal carcinomas,27 cases of DCIS and 14 cases of DCIS with microinvasion identified by postoperative pathological were collected,and their mammographic data were analyzed etrospectively.Results There were significantly more calci-fication and pure calcification in DCIS group than in IDC group(both P <0.05 ).And have no statistically significant difference be-tween those two diseases for the shap of calcification(P >0.05),both of them mostly showed granula and punctate calcification.There were statistically significant difference those two diseases for the distribution of calcification (P <0.05),the linearity and V-shaped segmental distribution occupies a relatively high percentage in DCIS while the cluster-like calcification occupies a relatively high percentage in IDC.Conclusion Pure calcification is mainly mammographic feature of DCIS.The characteristic of calcification is distribute along duct.

Objective To explore the correlation of human epidermal growth factor receptor type 2 overexpression (HER-2+)and mammographic and clinical features in breast cancers with estrogen receptor negative expression (ER-).Methods 190 cases of ER-breast cancer were included in this study.There were 78 cases with HER-2+,and 112 cases with HER-2-.The pathological and mammographic features were compared between the two groups.Results Compared with the HER-2- group,the HER-2+ group was more in older women (P<0.001)and more likely to have a lymphonodus metastasis (P=0.011).For mammographic manifesta-tions,pure calcifications were more detected in the HER-2+ group (P=0.000),and pure masses were more detected in the HER-2-group (P<0.001).The HER-2+ group was more likely showed as a lobulated mass (P<0.001),and with spiculated margin (P=0.000). However,the HER-2- group was more likely showed as a round mass (P=0.014),and with smooth margin (P=0.000).The cal-cifications of HER-2+ group were more likely showed as malignancy calcifications (P=0.000).Conclusion HER-2 overexpression breast cancer with ER- has some mammographic and clinical features,which is helpful for individual diagnosis and treatment.

Objective To explore whether albumin corrected anion gap (ACAG) is associated with long-term mortality of sepsis patients.Methods Adult patients with a diagnosis of sepsis within the first 24 hours (from December 2013 to December 2014) admitted to the intensive care unit (ICU) were included via the Sepsis database of West China Hospital Sichuan University. To record their long-term survival, patients were followed up by telephone interview one year after enrollment. ACAG was calculated according to the anion gap (AG) level within the first 24 hours admitted to ICU, and patients were divided into normal ACAG group (ACAG 12-20 mmol/L) and high ACAG group (ACAG > 20 mmol/L), and clinical characteristics and 1-year mortality were compared between groups. Patients were also divided into survivors and non-survivors according to the 1-year survival outcome, and multivariate logistic regression analysis was conducted to find independent risk factors for long-term mortality of sepsis patients.Results A total of 296 sepsis patients were enrolled in the study, with 191 (64.5%) in the high ACAG group and 105 (35.5%) in the normal ACAG group. There were no significant differences in age, gender, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ), sequential organ failure assessment (SOFA), Charlson cormobidity index (CCI) and other background variables between groups. Compared with the normal ACAG group, patients who suffered from multiple organ dysfunction syndrome (MODS) in the high ACAG group were more prone to develop renal and gastrointestinal injury (43.5% vs. 25.7%, 52.9% vs. 33.3%, respectively), had significantly higher serum creatinine [SCr (μmol/L): 89.0 (61.0, 148.0) vs. 67.1 (48.0, 86.0)], greater need for continuous renal replacement therapy (CRRT, 16.8% vs. 6.7%), and significantly shorter length of ICU stay and hospital stay [days: 11 (5, 22) vs. 16 (18, 31), 21 (14, 39) vs. 28 (20, 47)], with statistically significant differences (allP < 0.05). It was shown by Kaplan-Meier survival analysis that 1-year cumulative survival for the high ACAG group was significantly lower than that of the normal ACAG group (55.0% vs. 67.7%,P = 0.046). It was shown by multivariate logistic regression that ACAG [odds ratio (OR) = 1.201, 95% confidence interval (95%CI) = 1.115-1.293,P = 0.000], APACHE Ⅱ (OR = 1.053, 95%CI = 1.011-1.098, P = 0.014), the incidence of septic shock (OR = 2.203, 95%CI = 1.245-3.898,P = 0.007), fungus infection (OR = 3.107, 95%CI = 1.702-5.674,P = 0.000), acute renal failure (OR = 2.729, 95%CI = 1.134-6.567,P = 0.025) and complicated with malignancy (OR = 2.929, 95%CI = 1.395-6.148,P = 0.005) were independent risk factors contributing to increased 1-year mortality among sepsis patients.Conclusion ACAG was an independent risk factor for 1-year mortality of sepsis patients.
