Chinese Journal of General Surgery 2000;0(11):-
Objective To study the expression of small breast epithelial mucin(SBEM) in the peripheral blood of the patients with breast cancer,and explore the correlation between micrometastasis and SBEM.Methods Peripheral blood samples were obtained from 92 patients with breast carcinoma,20 patients with benign breast diseases,10 patients with malignant tumor not originating from breast,and 10 normal healthy volunteers.SBEM-mRNA expression was detected by nested reverse transcription-polymerase chain reaction(Nested-RT PCR).Results Among 92 breast carcinoma patients,43(46.7%) were Nested-RT-PCR positive for SBEM-mRNA,but it was negative in all the other groups.The expression of SBEM-mRNA in peripheral blood did not correlate with ER or PR status,menstruation state or primary tumour size.but correlated with patient′s age,the state of Her-2,CEA,CA15-3 and axillary lymph node metastasis of breast cancer.Conclusions The expression of SBEM-mRNA in peripheral blood of breast cancer can be of potential use to monitor the micrometastasis of breast cancer.

Objective:To screen the differentially co-expressed genes in the mRNA expression profile of colon cancer by combined application of weighted gene co-expression network analysis(WGCNA) and differential gene expression analysis, and to analyze the relationship between differentially co-expressed genes and prognosis.Methods:The transcriptomics data of the cancer genome atlas (TCGA)-colon adenocarcinoma (COAD) dataset and chip expression profile data of GSE68468 dataset were downloaded from TCGA and gene expression omnibus (GEO) databases based on bioinformatics methods, and differentially expressed gene (DEG) and the most significantly related weighted gene modules between normal tissues and colon cancer tissues were screened. Then, the differentially co-expressed genes related to colon cancer were screened out according to the intersection of differential genes and weighted genes. A protein-protein interaction (PPI) network was constructed, and the top ten core differentially co-expressed genes according to the maximal clique centrality (MCC) score were screened out by MCC calculation method. The expression of core genes in normal tissues and colon cancer tissues were further verified by TCGA-COAD dataset. Kaplan-Meier survival analysis was used to investigate the correlation between core genes and overall survival time and disease-free survival time of patients. The survival-related differentially co-expressed genes were verified by immunohistochemical staining in human protein atlas (HPA) database.Results:A total of 3 481 DEG of the TCGA-COAD dataset and 7 275 DEG of the GSE68468 dataset were screened out, and totally 237 differentially co-expressed genes were obtained. Ten core differentially co-expressed genes were obtained by the MCC calculation method of the PPI network, which were chloride channel accessory 1 ( CLCA1), mitogen-activated protein kinase 3, glucagon ( GCG), solute carrier family 26 member 3 ( SLC26 A3), nuclear receptor subfamily 1 group H member 4 ( NR1 H4), fatty acid binding protein 1 ( FABP1), guanylate cyclase activator 2A ( GUCA2 A), uridine diphosphate glucuronosyltransferase family 2 member A3 ( UGT2 A3), carnitine palmitoyltransferase 2 ( CPT2) and membrane spanning 4-domains A12 ( MS4 A12). Compared with those of the normal tissues, CLCA1, GCG, SLC26 A3, NR1 H4, FABP1, GUCA2 A, UGT2 A3, CPT2 and MS4 A12 of colon cancer tissues of the TCGA-COAD dataset were all down-regulated (all P<0.05). Among them, the overall survival time and disease-free survival time of patients with colon cancer with high expression of CLCA1 were both longer than those with low expression (both P<0.05). The results of immunohistochemical staining also verified the accuracy of the results at the protein level. Conclusions:CLCA1 may play a key role in the development of colon cancer, and it can be used as a potential biomarker for further diagnosis and treatment.

Objectives To explore the efficacy of CaNa2EDTA in the treatment of chronic moderate lead poisoning, so as to optimize the chelation therapy for lead poisoning in children. Methods The clinical data of 14 patients with chronic moderate lead poisoning treated with CaNa2EDTA for 3 consecutive courses of lead removal during September 2014 to December 2016 were analyzed retrospectively. Twenty-four hour urinary lead levels during hospitalization were analyzed. The changes of blood lead levels before treatment, 3 days, and 5 days after treatment were also analyzed. Results In the 14 children (4 males and 10 females) average age was 2.35±1.47 years. After treatment with CaNa2EDTA for 3 consecutive courses, the blood lead levels were decreased significantly in all the patients, and the blood lead levels at 3 days after treatment were 0.76, 0.77, 0.72 times those at 5 days after treatment respectively. The decrease of blood lead levels per unit of drug in the first 3 days of treatment were significantly higher than those in 5 days of treatment (P<0.05). The decrease of blood lead levels at 3 days after treatment was 0.65, 0.71, 0.70 times , those in 5 days' treatment respectively. The decrease of urine lead levels per unit of drug in the first 3 days of treatment were significantly higher than those in 5 days of treatment (P<0.05). Conclusions CaNa2EDTA has an obvious effect on removal of lead.The efficiency of lead removal in 3 days of treatment was higher than in 5 days of treatment. Thus, a course of treatment for 3 days may be an altenative for a course of 5 days.

BACKGROUND:Abnormal hippocampal neurogenesis during aging has been reported to result in learning and memory dysfunction. But its mechanism is unclear.
OBJECTIVE: To understand the changes of mouse neurogenesis in the hippocampal subgranular zone during aging.
METHODS:C57BL/6 mice 2, 6 and 20 months of age were used. Immunochemistry was used to count the number of neural stem cels (nestin+), neuroblasts (Doublecortin+, DCX+), and proliferative cels (proliferating cel nuclear antigen+, PCNA+) in the hippocampal subgranular zone. mRNA expressions of aging-related genes, p19Arf and p21Cip1/Waf1, in the hippocampus were detected by reverse transcription-PCR.
RESULTS AND CONCLUSION: Compared with the young and middle age groups, the number of PCNA+ cels, nestin+ and DCX+ cels in the hippocampal subgranular zone of the aged group decreased dramaticaly; the expression of p19Arf and p21Cip1/Waf1 mRNA increased in the aged group. Proliferation activity, the number of neural stem cels and neuronal differentiation al decreased. These findings indicate that the decline of hippocampal neurogenesis may be associated with increased expression of aging-related genes p19Arf and p21Cip1/Waf1 in the p19Arf-Mdm2-p53-p21Cip1/Waf1pathway.
