Objeetive To investigate the relationship between 24-hour blood pressure rhythm and carotid scleratheroma in elderly patients with hypertension.Methods 193 elderly patients with hypertension were enrolled in the study and divided into study group (91 cases with carotid atherosclerosis) and control group (102 cases).All the patients were given 24h blood pressure rhythm examination.The characteristics of 24hour blood pressure rhythm was compared between the two groups.Results The 24h average systolic blood pressure(24h-SBP),24h average diastolic blood pressure (24h-DBP),24h average pulse pressure (24h-MBP) between the study group and the control group had no significant differences(P ＞ 0.05).The daytime average systolic blood pressure(d-SBP),diurnal mean diastolic blood pressure (d-DBP),diurnal average pulse pressure (d-MBP),nocturnal mean systolic blood pressure (n-SBP),nocturnal mean diastolic blood pressure(n-DBP),nocturnal mean pulse pressure(n-MBP) of the study group were significantly higher than those of the control group (t =16.92,24.68,6.16,12.87,11.59,6.35,all P ＜0.05).In study group,d-SBP,d-DBP,d-MBP were higher than n-SBP,n-DBP,n-MBP,the differences were statistically significant(F =73.61,P ＜ 0.01).The circadian blood pressure variability of the study group was more than 10％,the 24h ambulatory blood pressure curve graph of the study group was non-dipper curve.The circadian blood pressure variability of the control group was less than 5％,the 24h ambulatory blood pressure curve was dipper type curve.Conclusion The MBPS is strongly associated with carotid scleratheroma,and clinical treatment and study could derive from ABPM data analysis.

Objective To determine the expressions of transcription factor activator protein-2α (AP-2α), estrogen receptor-β (ER-β) and matrixmetalloproteinase-9 (MMP-9) in lichen planus (LP) lesions and their significance. Methods Tissue samples were resected from the lesions of 30 patients with LP and normal skin of 30 human controls. An immunohistochemical method using streptavidin-peroxidase (SP) was performed to detect the expression of ER-β and MMP-9, reverse transcription-PCR and Western blot to measure the mRNA and protein expressions of AP-2α, ER-β and MMP-9 in these specimens. Results There was a significant decrease in the mRNA expressions of AP-2α (0.488 ± 0.039 vs. 1.008 ± 0.023, P < 0.01 ) and ER-β (0.365 ± 0.032 vs. 0.998 ± 0.036, P < 0.01), together with an increase in the expression of MMP-9 (1.237 ± 0.027 vs. 0.567 ± 0.015, P< 0.01) in the LP lesions compared with the control specimens; similar results were observed for the protein expressions of AP-2α, ER-β and MMP-9. In LP lesions, the expression of AP-2α was positively correlated with that of ER-β (R = 0.89, P < 0.01), but negatively correlated with that of MMP-9 (r = -0.91, P < 0.01). Conclusions The down-regulation of ER-β expression and up-regulation of MMP-9 expression may be ascribed to the abnormal regulation of upstream target genes mediated by the decreased expression of AP-2α, which may be involved in the pathogenesis of LP.

Microglia(MG)is recognized as the main immune effector in central nervous system injury and disease.MG can regulate the tumorigenesis and development of brain metastases tumor(BMT)by different ways.Studing the roles and mechanisms of MG in BMT will provide new insights into the prevention and treatment of BMT.

Cancer-related fatigue survivors have been found to have lower morning serum cortisol levels, flattened diurnal cortisol cy-cles, and decreased cortisol responses to psychological stress. The mechanism may be related to the inflammation caused by disorder of hy-pothalamus-pituitary-adrenal axis, and there are also some evidences to support that cortisol can be used to reduce cancer-related fatigue. This study introduced the research progress of the relationship between cancer-related fatigue and hypothalamus-pituitary-adrenal axis.

Objective To evaluate the efficacy of CHOP (cyclophosphamide,doxorubicin,vincristine,and prednisone)chemotherapy on peripheral T cell lymphomas-unspecified (PTCL-U)in patients aged 80 years and over,and investigate the chemotherapy adverse effects and its prognostic factors.Methods Clinical data of 57 patients with PTCL-U confirmed by pathology and immunohistochemistry in Guangzhou First People's Hospital from January 2008 to January 2015 were retrospectively analyzed.The efficacy and adverse effects of CHOP chemotherapy,and its prognostic factors were evaluated.Results Of 57 patients,11 (19.3％) achieved complete remission,23(40.4％)had partial remission,14(24.6％)had stable disease,and 9(15.8％)had progressive disease after CHOP chemotherapy,with a total effective rate of 59.6％ (34 cases).The expected 1-year,2-year and 3-year overall survival(OS)rate was 70.2％ (40 cases),36.8％ (21 cases) and 17.5％ (10 cases),respectively.The median survival time was 18.2 months.Among the 57 patients,40(70.2％) had hypoplasia of bone marrow at degree Ⅰ-Ⅱ,17 (29.8％) at degree Ⅲ-Ⅳ,49 (86.0％) had mild nausea and vomiting(degree Ⅰ-Ⅱ),8(14.0％)had severe nausea and vomiting(degree Ⅲ-Ⅳ),7 had liver dysfunction,2 had cardiac toxicity and 7 had disturbance of blood coagulation.Univariate analysis showed that the alkaline phosphatase,Ki-67 percentage,lymphoma international prognostic index(IPI)score,extranodal involved sites(＞1),as well as the efficacy and course of chemotherapy were the prognostic factors for survival time in very elderly patients.Multivariate analysis indicated that IPI score＞2(95％CI:1.12～6.35,x2 ＝5.45,P＜0.01),extranodal involved sites(＞1)(95％ CI:2.58-15.32,x2 ＝ 16.42,P＜0.01),disease progression(95％CI:1.82～12.15,x2 ＝ 10.23,P＜0.01),chemotherapy courses(＞4) (5％CI:0.18～0.79,x2 ＝7.28,P＜0.01)were the independent prognostic factors for the median survival time in very elderly patients.Conclusions PTCL U patients aged 80 years and over have poor prognosis.CHOP chemotherapy has a certain effect on PTCL-U in very elderly patients,and chemotherapy side effects can be tolerated.IPI score＞2 and extranodal involved sites(＞ 1)are the important prognostic factors in very elderly PTCL-U patients.The completion of full course of chemotherapy with remission occurrence is important to prolong survival time in very elderly PTCL-U patients.

The centrosome plays a crucial role in the maintaining of cell conformation,mitosis and chromosome seg-regation.It responds to the DNA damage and keeps the genome stability via cross-talking with the intranuclear DNA damage repair system.The apoptosis of tumor cells can be induced through inhibition of the duplication of centro-some.So the inhibitors of centrosomal proteins will be a potential anti-tumor therapy.

Acute non-variceal upper gastrointestinal bleeding (ANVUGIB)is one of the most common medical emergencies in China and worldwide. In 2009,we have issued the Guidelines for the diagnosis and treatment of acute non-variceal upper gastrointestinal bleedingin China;however,numerous studies on the diagnosis and treatment of ANVUGIB have been conducted in the past years,and the management of ANVUGIB needs to be updated. Finally,the 2015 version of Guidelines for the diagnosis and treatment of acute non-variceal upper gastrointestinal bleedingwas issued. We hope to provide information and help for understanding the new guidelines by clinicians.

Objective:To explore the therapeutic effect of the use of budesonide for externally-used budesonide in the surgical cavities following endoscopic sinuous surgery(ESS).Method:122 cases with chronic sinusitis were randomly divided into two groups treated by the routine procedures after endoscopic sinuous surgery but the treatment group with 61 cases were treated by the addition of budesonide suspension for inhalation in the surgical cavities.The process of the epithelization in the surgical cavities by endoscopy was investigated.Result:The process of cleaning in 15 days in the surgical cavities was better in the budesonide-using group than in the controlled group.A significant difference was found(P
