ABSTRACT
To investigate the correlation between the number of peripheral blood circulating tumor cells (CTCs) and clinicopathological features of early breast cancer. Methods: The clinical and pathological data from 100 patients with early breast cancer treated by a breast cancer treatment team in the Department of Breast Surgery, Second Xiangya Hospital, Central South University, were collected from January 2017 to December 2018. For these patients, their peripheral blood CTCs were detected, enumerated and typed by CanpatrolTM CTC assay. Results: The positive rate of CTCs was 90% in peripheral blood of patients with early breast cancer, and the majority of molecular phenotypes was hybrid CTCs (55.6%). The positive rate of CTCs was only related to the pathological type of tumor (P<0.05), but not to other clinicopathological features. No correlation between clinicopathological features and the total number of CTCs, the number of epithelial CTCs or the number of hybrid CTCs was found. However, the number of mesenchymal CTCs was significantly correlated with the expression of hormone receptors and Ki-67 (r=0.200, P<0.05), and there was a significant correlation between the proportion of mesenchymal CTCs and the expression level of Ki-67 (r=0.213, P<0.05). Conclusion: The number of CTCs is not correlated with all clinicopathological features, but patients with negative hormone receptor and high expression of Ki-67 probably have more hybrid CTCs.

Objective The objective of this study was to explore the difference factors for PHC patients by transcatheter arterial chemoembolization of different age groups of senior people in China and support reference for individualized intervention by clinical medical workers.Methods 153 cases of PHC patients by TACE were selected by convenience sampling method from October 2013 to June 2014.The data were collected using general data questionnaire,Health Promotion Strategy Scale,QOL-LC,Memorial Symptom Assessment Scales and Social Support Scale to evaluate the physical,psychological and social aspects of the PHC patients.We divided the patients into young,middle-aged and elderly groups.Single factor and multiple factors regression analysis were used to compare the status and influencing factors.Results Psychological function,value of blood AFP,marital status entered the model and were self-care efficacy and correlated factors of young-aged patients,which could explain 50.6％ of the total varience.Physical symptoms,exploitation degree of support and intervention treatment times entered the model and were self-care efficacy and correlated factors of middle-aged patients,which could explain 47.8％ of the total varience.Symptom distress,degree of cuhural and psychological function entered the model and were self-care efficacy and correlated factors of elderly-aged patients,which could explain 42.4％ of the total varience.Conclusions The self-care efficacy were low in all ages of PHC patients by TACE,it is associated with a variety of factors.Doctors and nurses should pay more attention to the self-care efficacy for PHC patients by transcatheter arterial chemoembolization with different age groups.Also we should evaluate and make well-targeted policies and personalized inter-ventions to promote self-management self-efficacy.
ABSTRACT
Objective To investigate the predisposing factors and fungal characteristics of nosocomial fungal infection (NFI) in patients with chronic kidney disease (CKD). Methods The fungal characteristics and laboratory indices were analyzed in patients with and without NFI secondary to CKD. Results The most common infection site of NFI in 65 cases patients with CKD was urinary tract (25 man-times, 38.46%), and the second common site was digestive tract (20 man-times, 30.77%). The most common pathogenic fungus was Candida albicans (68.49%), followed by Candida tropicalis (17.81%). The sensitivity of Candida albicans to fluconazol was 90%. The predisposing factors included prolonged length of stay, anaemia, malnutrition, hypogammaglobulinemia, mass proteinuria, renal insufficiency, and the use of large dose of broad spectrum antibiotics, prednisone and cytoxan. Conclusion CKD may predispose to NFI, and the most common fungus is Candida albicans,so the predisposing factors should be controlled so as to prevent NFI among patients with CKD.
ABSTRACT
AIM:Activin A,a member of transforming growth factor superfamily,is the negative regulator factor in liver regeneration. In this study,the effects of extract of Ginkgo Biloba on hepatic fibrosis and the expression of Activin A in rats with cirrhosis were investigated. METHODS:The experiment was performed at in the Central Laboratory of Wuhan First Hospital from September 2005 to December 2006. ①Thirty-six male SD rats of(160?20) g were randomized into 3 groups:control group,model group and treatment group. ② Except the rats in the control group,others were intraperitoneally injected with 500 mL/L CCl4 for 8 weeks to establish models of hepatic fibrosis. Meanwhile,the extract treatment group was infused with the extract of Ginkgo Biloba(Chinese drugs preparation laboratory of Wuhan First Hospital,detected by Hubeu Wushi Medicine Industry Co.,Ltd. No. 02-391) daily for 8 weeks. ③After administration,all anesthetized rats were sacrificed. Blood samples were collected for the determination of liver function biochemical indexes. Liver tissue samples were used for histopathological examinations. The expression of Activin A was determined by immunohistochemistry and RT-PCR. RESULTS:All 36 rats were involved in the final analysis. ①The liver function in extract treatment group was significantly improved compared with that in model group. ②The grade of fibrosis in extract treatment group were remarkably lower than that in model group under light microscope. ③The positive staining of Activin A in treatment group was significantly reduced compared with model group. ④The expression of Activin A mRNA in extract treatment group was significantly reduced compared with model group. CONCLUSION:Extract of Ginkgo Biloba can effectively decrease the expression of Activin A in rats with hepatic fibrosis caused by CCl4,and lessen the degree of hepatic fibrosis.
ABSTRACT
OBJECTIVE: To observe the effects of Huobahuagen Tablets combined with irbesartan on the risk factors of IgA nephropathy. METHODS: Sixty-two patients diagnosed as IgA nephropathy were randomly divided into control group and treatment group. Thirty patients in the control group were treated with Huobahuagen Tablets (5 tablets po t.i.d.), and 32 patients in the treatment group were treated with irbesartan (150 to 300 mg po q.d.), besides the same treatment as the control group. After 3 months of treatment, the levels of blood pressure (BP), 24 h urine protein (Upr), urinary red blood cells (URBC), blood triglycerides (TG), total cholesterol (TC), albumin (Alb), alanine transaminase (ALT), white blood cells (WBC) and serum creatinine (Scr) were observed. RESULTS: After treatment, the levels of Upr, URBC and Scr in both groups were decreased, as compared with those before treatment (P<0.05 or P<0.01), and the levels of BP, Upr, URBC and Scr in the treatment group were lower than those in the control group (P<0.01). The levels of Alb in both groups were increased, as compared with those before treatment (P<0.05 or P<0.01), and the level of Alb in the treatment group was higher than that in the control group (P<0.05). CONCLUSION: Huobahuagen Tablets, when used together with irbesartan, may improve the renal function of the patients with IgA nephropathy and slow the deterioration of the disease by reducing BP, Upr, URBC and Scr.
