It is important and challenging for geriatricians and general practitioners to detect early and diagnose senile dementia in outpatient setting.After providing the definition of dementia,this article will discuss prompt recognition of dementia based on symptoms and signs, the neuropsychological assessment,and the biomarkers of dementia,as well as differential diagnoses.

Triple-negative breast cancer (TNBC) in elderly patients presents distinctive clinicopathologic characteristics of large volume and histological grade Ⅲ,and it is seen most frequently in invasive ductal carcinoma,adenocarcinoma and lobular carcinoma.Elderly women with TNBC significantly benefit from adjuvant chemotherapy.But older women frequently have concurrent disease,so neoplasm staging,function of vital organs and tolerance of patient should be considered when treatment programs are selected.The prognosis of older TNBC patient is worse,but rational therapy can improve outcomes significantly.

OBJECTIVE: To observe the clinical efficacy of nimodipine combined with Shengmai injection on hypertensive cerebral hemorrhage. METHODS: 24 patients with hypertensive cerebral hemorrhage hospitalized within 24 hours of symptom onset were randomly divided into control group and treatment group. Both groups were given routine treatment, including reducing intracranial pressure and blood pressure and nourishing brain cells. Treatment group were additionally given nimodipine and Shengmai injection. The intracranial hematoma, perihematomal edema and CSS score were observed and compared between two groups as well as clinical efficacy. RESULTS: After 2 weeks of therapy, the level of intracranial hematoma, perihematomal edema and CSS score of treatment group were lower than that of control group, with statistical significance (P

Objective: To identify the existence of the specific NMP in the human normal colon tissues and different differentiation of colon carcinoma,and try to study the association between changes of nuclear matrix protein and biological behaviar of colorectal colon carcinoma.Methods:Two-dimensional gel electrophoresis was used in the analysis of 12 matched human colon carcinomas and adjacent normal samples.MMP-9 and CB were detected by immunohistochemical SP method.Results: Analysis of multiple gels for each sample revealed that 5 proteins were present in tumor samples,but not in the matched normal colon tissues;and 3 proteins in normal colon tissues but not in the colon carcinomas.There were different NMPs in different types of colon carcinoma.One nuclear matrix protein(called N4) appeared in 9 moderate-well differentiational colon carcinomas without lymph node metastasis and in 12 normal colon tissues,but were absent in 3 poor differentiational colon carcinomas with lymph node metastasis.The result of immunohistochemistry showed that the expression of MMP-9 and CB in poor differentiational colon carcinoma which was lack of expression of NMP N4 was strongly positive,and was stronger than that in the moderate-well differentiational colon carcinomas which expressed NMP N4.Conclusion: The data suggests that there are colon carcinoma-specific NMPs.There are different NMPs in different types of colon carcinomas,and with or without lymph node metastasis.Colon carcinoma-specific NMPs may serve as the tumor markers of colon carcinoma in future.There is a relation between changes of nuclear matrix protein and lymph node metastasis of colorectal colon carcinoma;the changes of NMPs probably play a role in MMP-9 and CB expression of colon carcinoma.

With the development of medical radiography, cone beam computed tomography (CBCT) has been widely used in stomatology because of its numerous advantages, such as adequate spatial resolution, low radiation, undistorted three- dimensional tissue information, and good applicability for hard tissue imaging. Traditional periapical radiography is based on two-dimensional image which displays the three-dimensional object and its surrounding structures. Periapical radiography can only show the overlapping mesio-distally direction bone destruction, can't show buccolingual direction bone destruction. As a kind of three-dimensional imaging technology, CBCT can show three-dimensional structure of the organization from sagittal, coronal and axial direction, to overcome the defect of two-dimensional image such as overlap and deformation. CBCT has a unique advantage than periapical radiography in the diagnosis and treatment for periapical disease. This review will summarize the difference between CBCT and periapical radiography in the periapical disease.

OBJECTIVETo observe the dynamic changes of membrane-bound proton-translocating ATPase (F-ATPase) in the development of dental caries, the expression of Streptococcus mutans F-ATPase under different pH concentrations and during the development of dental caries is analyzed.

METHODSStreptococcus mutans cultured under different pH (pH4.0-7.0) concentrations and containing 5% glucose and no glucose containing BHI were collected. RNA was extracted. Subsequently, F-ATPase gene was detected using real-time polymerase chain reaction. Male Wistar rats were divided randomly into caries group and control group. The rats in the caries group were fed caries feed and 5% glucose water, whereas those of control group were fed normal feed. Total RNA was extracted from plaque samples, which were collected from rats' oral cavity every two weeks. F-ATPase gene was detected by real-time PCR. In the 11th week, the upper and lower jaw bone specimens of rats were taken, and molar caries damage assessed.

RESULTSThe expression of F-ATPase in the caries group was higher than that in the control group (P<0.05). In addition, the gene was expressed highest in pH5.0 and the lowest in pH4.0 (P<0.05). 2) The expression of F-ATPase progressively increased during the caries development in both groups; expression in the caries group was higher than that in control group (P<0.05).

CONCLUSIONAcid-resisting viru-lence factor F-ATPase is related closely with the incidence and development of dental caries.

In 2014, The Cancer Genome Atlas firstly classified gastric cancer into four types according to genotype. Epstein-Barr virus (EBV) positive gastric cancer or EBV-associated gastric cancer (EBVaGC) is attracting attention because it is a possibly suitable group for immunotherapy. Among the mutations observed in tumors, such as gastric cancer, p53 mutations are the most frequent. In particular, it occurs more frequently in EBVaGC than in EBV-negative gastric cancer (EBVnGC). Meanwhile, EBV infection is considered as an early event of tumorigenesis. The interactions between wild-type p53 proteins and BZLF1 (Z) proteins are essential in maintaining the latent state of EBV infection and promoting early replication. In the latter stages of replication, wild-type p53 proteins are degraded through the ubiquitination of some viral molecules. These findings may indicate the importance of wild-type p53 genes in EBVaGC formation. Inflammatory responses induced by EBV infection, tumor with a large number of lymphocyte infiltration, genome high mutation, and PD-L1 amplification make it possible to become the appropriate group of immunotherapy, which also illustrate that the important role of immune microenvironment during tumor progression. In EBVnGC, extremely high levels of p53 mutation were observed because of several associated factors, and the p53 protein encoded by the mutant p53 gene lost its antitumor function after tumorigenesis. In this review, the possible mechanisms of rare p53 mutation in EBVaGC are summarized.

Objective To investigate the expression of multidrug resistance protein 1 (MDR1) and brain and acute leukemia cytoplasm (BAALC) genes and its relationship with prognosis in patients with newly diagnosed acute myeloid leukemia (AML).Methods A total of 100 adults with newly diagnosed AML were enrolled in the study.All patients were treated with anthracyclines induced chemotherapy combined with cytarabine.The expression levels of MDR1 and BAALC genes were detected,and the relationships with the clinical characteristics of patients with AML,genetic type,therapeutic effect and prognosis were analyzed.Results There was no significant differences in white blood cells,hemoglobin and platelet between patients with high and low expression of MDR1 gene and BAALC gene (P>0.05).There were significant differences in the expression level of MDR1 gene between patients with different chromosome risk stratification (P<0.05) but there was no significant difference in the expression level of BAALC gene (P>0.05).After chemotherapy intervention,CR of patients with high expression of MDR1 gene was significantly lower than patients with low expression of MDR1 gene (60.78% vs.87.76%)(P<0.05),CR of patients with high expression of BAALC gene was slightly lower than patients with low expression of MDR1 gene (67.31% vs 81.25%)(P>0.05).Comparison of median overall survival (OS) and overall survival (OS) in patients with high and low expression of MDR1 gene.The difference was statistically significant (P<0.05).Comparison of median overall survival (OS) and overall survival (OS) in patients with high and low expression of BAALC gene.There was no significant difference(P>0.05).Conclusion Compared with the expression of BAALC gene,the value of expression of MDR1 gene is higher in evaluating the curative effect in patients with newly diagnosed AML.Combined detection of MDR1 and BAALC genes can improve the accuracy in predicting the prognosis of patients.
