Objective To investigate the correlation of the 24?hour ambulatory systolic blood pressure (SBP) and carotid intima?media thickness(CIMT) in the elderly. Methods A total of 2 464 who were more than or equal to 60 years old participants were selected with random sampling in accordance with the inclusion criteria from the retired workers in Tangshan Kailuan Company. Dynamic blood pressure monitoring, neck vascular ultrasound and other examination were performed for the participants. . Multivariable linear regression analysis was used to analyze correlation between the SBP of 24?hour, daytime and nightime with CIMT, respectively. Results ( 1) The observation population was divided into three groups according to the tertiles of SBP of 24?hour, daytime and nightime, respectively. With the levels of different SBPs inceasing, CIMT values thickened markedly ( P<0. 01 ) . ( 2 ) Multivariable linear regression analysis showed that after adjusting for confounding factors,the SBP of 24?hour,daytime and nightime associated with CIMT positively and linearly(P<0. 05),and regression coefficient(95%CI) were 0. 022(0. 009-0. 035), 0. 021(0. 008-0. 035), 0. 019 ( 0. 006-0. 032) respectively. In addition,clinic SBP step into the multivariable linear regression,and regression coefficient ( 95%CI ) were 0. 016 ( 0. 003-0. 029 ) , 0. 016 ( 0. 003-0. 030 ) , 0. 019 ( 0. 007-0. 032 ) , respectively. Conclusion The effect of increased 24?hour ambulatory SBP on CIMT was greater than the clinic SBP. Active monitoring of 24 h ambulatory blood pressure and maintaining a low level of blood pressure is essential for preventing and delaying atherosclerosis.

Objective To explore the relationship between different blood glucose levels and new carotid artery plaques.Methods A total of 5 440 participants met the inclusion criteria were selected stratified randomly from the 101,510 serving and retired workers of Tangshan Kailuan Company who participated the health examination from 2006 to 2007.The follow-up health examination were respectively preformed from 2010 to 2011 and from 2012 to 2013 which included carotid ultrasound for these 5 440 participants.The 5 440 participants were divided into three groups (ideal blood glucose group,impaired fasting glucose group and diabetic group) according to their fasting glucose levels in 2010-2011 examination.Multivariate Logistic regression analysis was used to analyze the risk factors of new carotid artery plaques.Results Among 5 440 subjects,participants whose FPG,ultrasound data incomplete and ultrasound detection of carotid plaques during the 2010-2011 health examination were excluded,then 3 084 participants were included in this study,among them,175 participants who did not participate the 2012-2013 health examination and 561 participants whose carotid plaque ultrasound data incomplete were excluded.Thus,a total of 2 348 participants were included in the present analysis.The total detection of new carotid artery plaque rate was 15.0％ (352/2 348) after 2 years of follow-up.The detection of new carotid artery plaque rate in normal glucose group(n =1724),impaired fasting glucose group(n=464) and diabetic group(n=160) were 14.2％(245/1 724),14.9％(69/464) and 23.8％(38/160),respectively.The diabetic group was higher than that of the ideal blood glucose group and the impaired fasting glucose group,the difference was statistically significant(P＜0.05).Impaired fasting glucose group and diabetic group had an increased risk of new carotid artery plaque compared with those in ideal glucose group(OR =0.924,95％CI 0.691-1.235 and OR =1.733,95％CI 1.107-2.713,respectively),the difference was statistically significant(P＜0.05).After adjusted for the other risk factors,with the risk-adjusted ratio (OR =1.117,95％CI 0.824-1.513 and OR =1.393,95％CI 0.872-2.226).Conclusion The detection of new carotid artery plaque increase in the diabetic group.However,after adjustment for other risk factors associate with emerging danger of new carotid artery plaque is no significant difference.This requires more long-term follow-up study of a large sample to be further confirmed.

[Objective] To investigate association between the time point of sorafenib administered and suppress effect on tumor growth secondary to the increased expression of vascular endothelial growth factor (VEGF).[Methods] Fifty SD rats were performed intrahepatic implantation using tumor tissues from subcutaneous tumors in nude mice which were administered Walker 256 tumor cells.Ten days after the procedure,MR scans were used to choose forty SD rats with successful hepatic tumor transplantation among fifty experimental animals.Then they were randomly divided into four groups:(A,control group) mere injection of vascular endothelial growth factor (VEGF);(B) administration of sorafenib 72 hours prior to VEGF injection;(C) administration of sorafenib together with VEGF injection;(D) administration of sorafenib 72 hours later to VEGF injection.The tumor growth and median survival time of rodents were observed and compared.After each experimental animal died,immunohistochemical (IHC) methods were applied to detect the expression of VEGF in tumors.[Results] Ten days after the administration of sorafenib,MR showed significant growth of hepatic tumors,the tumor size in experiment group were significiant smaller,than control group (5.4 cm) with statistical significance.Median survival time of four groups were (19.6 ± 1.8) d,(31.2 ± 7.0) d,(27.4 ± 4.9) d,and (26.5 ± 4.6) d,respectively,which indicated that animals in sorafenib groups lived longer than those in control group (P ＜ 0.05).Differences can be obseverd in sorafenib groups with statistical significance existing (P ＜ 0.05).Harvest hepatic tumor tissues from dead animals and HE staining as well as IHC examination were performed.The expression of VEGF in four groups were 88.3 ± 13.6,42.8 ± 8.0,71.9 ± 15.7,and 73.6 ± 13.7.There were statistical significance between control group and sorafenib groups.And further in sorafenib groups,the expressions of VEGF also varied greatly.[Conclusion] Sorafenib can extend the survival time,reduce tumor angiogenesis.And we can conclude that administration of sorafenib before the transient increased expression of VEGF offers survival benefits than that after the evaluation of VEGF levels.

Objective:To examine the validity and reliability of the Chinese version of the Body Acceptance by Others Scale-2(BAOS-2)in adults.Methods:Totally 616 adults(aged 18-56 years)were selected to test the structural validity,and internal consistency reliability of the scale.The Body Appreciation Scale-2(BAS-2),Func-tionality Appreciation Scale(FAS),Self-Compassion Scale(SCS),Self-Esteem Scale(SES)and Satisfaction with Life Scale(SWLS)were used as criteria to test criterion validity.A sample of 55 adults was retested 2 weeks later for the test-retest reliability.Results:The exploratory factor analysis extracted one factor,and the factor loading range of each item was 0.59-0.76.The confirmatory factor analysis showed that the factor model fit indices were acceptable(x2/df=2.99,CFI=0.91,GFI=0.90,TLI=0.89,RMR=0.04,RMSEA=0.08).The scores of the Chinese version of BAOS-2 were positively correlated with the scores of BAS-2,FAS,SCS,SES and SWLS(r=0.43-0.66,Ps＜0.001).The Cronbach a of the Chinese version of BAOS-2 was 0.90,and the test-retest reliabili-ty(ICC)was 0.65.Conclusion:The Chinese version of the Body Acceptance by Others Scale-2(BAOS-2)has i-deal validity and reliability.

OBJECTIVE:To compare clinical efficacy and safety of clopidogrel and ticaprelor in the treatment of acute non-ST elevation myocardial infarction (NSTEMI).METHODS:A total of 160 NSTEMI patients admited in cardiovascular disease department of our hospital during Oct.2013-Nov.2015 were divided into observation group and control group according to random number table,with 80 cases in each group.Both groups received routine treatment and continues intravenous pump of Tirofiban hydrochloride sodium chloride injection at 0.05 μg/(kg·h).Control group was additionally given oral loading-dose of Clopidogrel hydrogensultate tablet 300 mg,adjusted to 75 mg,qd,on the basis of routine treatment.Observation group was additionally given oral loading-dose of ticaprelor 180 mg,adjusted to 90 mg,bid,on the basis of routine treatment.Both groups received 1 month of treatment.The rate of platelet aggregation,LVEF,LVEDD,fibrinogen levels,the incidence of MACE and bleeding events were compared in 2 groups before and after treatment.RESULTS:Before treatment,there was no statistical significance in the rate of platelet aggregation between 2 groups (P＞0.05).After 1 week and 1 month of treatment,the rates of platelet aggregation in 2 groups were decreased significantly,and the observation group was significantly lower than the control group,with statistical significance (P＜0.05).After 1 week of treatment,there was no statistical significance in the levels of LVEF or LVEDD between 2 groups (P＞0.05).After 1 month of treatment,LVEF of observation group was significantly higher than that of control group,LVEDD was significantly lower than control group,with statistical significance (P＜0.05).There was no statistical significance in the level of fibrinogen before treatment and after 3 d of treatment (P＜0.05).After 1 week and 1 month of treatment,the levels of fibrinogen in 2 groups were decreased significantly,and the observation group was significantly lower than the control group,with statistical significance (P＜0.05).The incidence of MACE in observation group was 11.25％,which was significantly lower than 25.00％ of control group,with statistical significance (P＜0.05).There was no statistical significance in the incidence of bleeding (3.75％ vs.7.50％) between 2 groups (P＞0.05).CONCLUSIONS:Compared with clopidogrel,ticaprelor effectively inhibits platelet aggregation in NSETMI patients,reduces the level of fibrinogen,improves cardiac function and prognosis and doesn't increase the risk of bleeding with good safety.

Objective To investigate the clinical manifestations of familial adenomatous polyposis(FAP).Methods The clinical data of 100 patients with FAP diagnosed in the First Affiliated Hospital of Zhengzhou University from 2011 to 2021 were analyzed retrospectively.Results The main clinical manifestations were bloody stool(44.0%),abdominal pain(40.0%),changes of stool characteristics(25.0%),abdominal distension(18.0%)and diarrhea(17.0%);The most common types of adenomas were villous tubular adenoma(44.9%)and tubular adenoma(32.1%);Extraintestinal manifestations:3 cases of desmoid fibroma,2 cases of osteoma and 1 case of lipoma.47 cases of gastric polyps and the mostly pathological type was fundic gland polyp(34.0%).18 cases of duodenal polyps including 6 cases of adenomatous polyps and most were located at descending duodenum(61.1%).Adenoma canceration occurred in 21 patients.The average age was 38.7 and the canceration mainly occurs in the rectum.The gender,family history,age of onset,number of adenomas,diameter and pathological type of adenomas were statistically compared between patients with and without canceration.It was found that there were significant differences in gender,average age of onset,number of adenoma polyps,diameter of adenoma and pathological type between the two groups(P<0.05).Conclusions FAP is mainly characterized by bloody stool and abdominal pain,with high canceration rate.The risk factors include the age of onset,the number and size of adenomas and the pathological type.The main pathological types are villous tubular adenoma and tubular adenoma.At present,preventive colorectal resection is still the most effective way to treat FAP.No matter what type of methods patients choose,they should be followed up strictly under endoscopy in order to find the lesions in time and treat if necessary.

OBJECTIVETo explore the impact of ideal health behaviors on the newly developed carotid plaques.

METHODSA total of 5 852 employees (including retired employees from Tangshan Kailuan company) aged over 40 years were included in this study through stratified random sampling. Subjects with previous stroke, transient ischemic attack, myocardial infarction were excluded. Results from the unified questionnaire, blood biochemistry measurements and ultrasonography carotid artery measurements were analyzed. Present study analyzed the data from 2 372 participants without carotid plaques in 2010-2011 examinations. The newly developed carotid plaques in 2012-2013 health examinations were observed and multiple logistic regression analysis was used to explore the impact of ideal health behaviors and factors on the newly developed carotid plaques.

RESULTS(1) There were 359 subjects with newly developed carotid artery plaques among the 2 372 subjects (15.1%), prevalence rate was 23.1% (43/186), 17.5% (186/1 065), 12.4% (122/986), 5.9% (8/135) in the groups with 0-1, 2-3, 4-5 and 6-7 components of ideal cardiovascular health behaviors and factors, respectively (P < 0.001). (2) Multiple logistic regression analysis showed that after adjusting for age, gender, high density lipoprotein cholesterol, heart rate, and high sensitive c-reactive protein, compared to with 0-1 components of ideal cardiovascular health behaviors and factors, participants with 4-5 and 6-7 components of ideal cardiovascular health behaviors and factors were associated with reduced risk of the newly developed carotid plaques, the OR (95% CI) values were 0.52(0.34-0.80) and 0.28(0.12-0.64), respectively.

CONCLUSIONHigher number of ideal cardiovascular health behaviors and factors is associated with lower incidence of newly developed carotid plaques.
