OBJECTIVESTo explore the significance of noninvasive central blood pressure detection in blood pressure management and vessel function assessment of hypertension.

METHODSA total of 348 subjects were recruited in the study and A-pulse CASP software were derived to measure the parameters of CASP and vessel function. The recruited subjects were divided into different groups for analysis according to age and disease.

RESULTS(1) CASP in hypertension group were both higher than those in normal group, while RAI and PRT lower. (2) Hypertensive patients of which brachial blood pressure were controlled have lower CASP and RAI than those above the level. (3) Hypertensive patients whose brachial blood pressure were controlled have significantly higher CASP than normal subjects.

CONCLUSIONSCentral blood pressure is more reflective of actural blood pressure and vessel function. Enhanced control of CASP in hypertensive patients contributes to improving vessel compliance.

Methods Three cases of spontaneous rupture of primary liver cancer were undertaken hepatic arterial chemoembolization with prior chemo-infusion and followed by gelfoam partical and stripes for embolization Results 3 cases of massive type of primary liver carcinoma with spontaneous rupture were all successfully once embolized, including one with additional super liquefied lipiodal as embolic agent who has been survived for more than 20 months. Conclusions Hepatic arterial chemo-embolization shows prominent hemostasis during emergency for spontaneous rupture of primary hepatic carcinoma providing double effectiveness of hemostasis and treatment.

Objective To investigate the influence of peer education on maintenance knowledge of patients with peripherally inserted central catheter (PICC) outside the hospital.Methods 74 patients with PICC were divided into the intervention group and the control group with 37 patients in each group according to the random digit table,the intervention group received peer education and the conventional health education,while the control group only received routine health education.The maintenance knowledge of PICC was investigated with questionnaires and the results were analyzed.Results xfter intervention,the maintenance knowledge of the intervention group was significantly higher than that of the control group [(36.95±2.84) scores vs.(31.78 ± 4.79) scores,t=5.639,P＜0.05].The incidence rate of complications in the intervention group was lower than that of the control group [21.6％ (8/37) vs.62.2％(23/37),x2=12.491,P＜0.01].Conclusions The peer education can improve patients' maintenance knowledge about PICC and reduce the occurrence rate of the complications of PICC.

AIM:To explore the effects of stanniocalcin 2 (STC2) on the proliferation, migration and the process of epithelial-mesenchymal transition (EMT) in human hepatocellular carcinoma HepG2 cells.METHODS:The expression levels of STC2 in the hepatocellular carcinoma cell lines and normal liver cells were assessed by Western blot.Colony formation assay was used to test the effect of STC2 on the proliferation of HepG2 cells.The effects of STC2 on the expression of proliferation-related molecules at mRNA and protein levels were determined by RT-qPCR and Western blot.The effect of STC2 on the migration ability was measured by Transwell assay.The mRNA and protein levels of vimentin and E-cadherin in STC2-overexpressing and-silencing cell lines were detected by RT-qPCR and Western blot.RESULTS:Compared with the normal liver cell line, the protein expression of STC2 was up-regulated in the hepatocellular carcinoma cell lines.The results of colony formation assay indicated that STC2 promoted the proliferation of HepG2 cells.STC2 significantly regulated the proliferation-related gene expression, such as cyclin D1.The results of Transwell assay showed that STC2 enhanced the migration ability of the HepG2 cells and influenced the EMT process.CONCLUSION:STC2 promotes the proliferation of HepG2 cells and affects the expression of proliferation-related genes.STC2 influences the process of EMT and promotes the migration of HepG2 cells.

AIM:To explore the mitochondrial pathway in the apoptosis of PC3 cells induced by PXD101 (also named as belinostat).METHODS:PC3 cells were treated with PXD101 at different doses or stimulated with PXD101 for different time.The effect of PXD101 on the viability of PC3 cells was measured by CCK-8 assay.The apoptotic rates and the mitochondrial membrane potential (MMP) were analyzed by flow cytometry.The protein levels of Bcl-2, Bax and cytochrome C (Cyt C) were determined by Western blot.The caspase-3 activity were tested by caspase-3 activity assay kit.RESULTS:The viability of the PC3 cells was inhibited by PXD101 in a dose-and time-dependent manner.Flow cytometric analysis showed that the apoptotic rates were increased in the cells treated with PXD101 (P<0.01).At the same time, PXD101 induced the decreases in MMP and Bcl-2, the release of Cyt C, and the increase in caspase-3 activity.CONCLUSION:PXD101 induces the apoptosis of human prostate cancer cell line PC3 by mitochondrial signal pathway.

Objective The aim of this study was to investigate FFDM differential diagnosis between breast mastitis,benign hyperplasia and breast cancer. Methods Fifty-nine cases of non-puerperal breast mastitis,sixty-eight cases of benign hyperpla-sia and two hundred and forty cases with non-mass type breast cancer were analyzed retrospectively,which were verified by surgery and pathology by contrast with FFDM signs,pathological types,grouped and statistics processed. The observation indexes of lamellar shadow included shape,density and edge. The observation indexes of linear shadow included direction,form and diameter. Results The FFDM signs in three groups of breast diseases were statistically significant(P<0. 05):the form of linear shadow,accompanied by calcifications,the shape of lamellar shadow,the direction of linear shadow,the distribution of lesion,the sharp angle of shadow edge. χ2 segmentation show that there were significant differences between three groups(P<0. 0125):the shape of lamellar shadow,the direc-tion of linear shadow. Conclusion There have some values for the diagnosis of breast cancer by rigid form and radial distribution of linear shadow,rigid shape and segmental distribution of lamellar shadow,the polymorphic calcifications and the sharp angle sign.

Objective:To study the antibacterial properties and in vivo and vitro biocompatibility of Cu-Fe-Zn alloy microfilament dressings, and to evaluate their wound healing promoting effect through clinical application.Methods:We evaluated the comprehensive antibacterial performance of dressings in vitro using plate counting method; After co culturing the extract of Cu-Fe-Zn alloy microfilament dressings with epidermal cells (HaCaT) and fibroblasts (NIH-3T3), their in-vitro biocompatibility was determined through the cell counting kit-8 (CCK-8) test; Further, Cu-Fe-Zn alloy microfilament dressing was applied to the wound surface of diabetes mice to test the biocompatibility of the material in vivo; Through a prospective randomized controlled trial, 50 burn and trauma patients admitted to the Burn and Plastic Surgery Department of the Third Xiangya Hospital of Central South University were selected and divided into an observation group of 25 patients and a control group of 25 patients. The observation group was treated with Cu-Fe-Zn alloy microfilament dressing, and the control group was treated with silver nanoparticle antibacterial dressing. The wound healing time and wound treatment effect of the two groups were compared.Results:The Cu 2+ release concentration of Cu-Fe-Zn alloy microfilament dressings detected by inductively coupled plasma-mass spectrometry (ICP-MS) was 1.3 μ g/ml, which had the effect of promoting the proliferation of HaCaT and NIH-3T3 cells (all P<0.05). The antibacterial rate of Cu-Fe-Zn alloy microfilament dressing against pseudomonas aeruginosa, escherichia coli and staphylococcus aureus reached 100%. The wound healing rate [(87.39±1.83)%] of diabetes mice treated with Cu-Fe-Zn alloy microfilament dressing was significantly higher than that of the control group [(58.66±3.54)%, P<0.05]. The inflammatory response of the wound tissue was relatively mild and the wound margin matrix was intact. The wound healing time of 25 patients treated with Cu-Fe-Zn alloy microfilament dressing [(23.52±10.02)d] was shorter than that of the control group [(40.84±21.22)d] ( t=17.159, P<0.001), and the overall treatment response rate of patients (96%) was significantly higher than that of the control group patients (64%) (χ 2=8.472, P=0.015). Conclusions:Cu-Fe-Zn alloy microfilament dressings have good antibacterial properties and biocompatibility, and have significant therapeutic effects on promoting wound healing. They not only effectively promote wound healing but also exert anti infection effects, and are expected to be a new type of wound repair dressing.

Objective:To develop a three-dimensional body image stimuli suitable for middle-aged people in China, and verify the validity and reliability of the body image stimuli.Method:According to China and World Health Organization body mass index classification standards of adults, a set of three-dimensional body image stimuli of Chinese middle-aged males and females with different body size was developed by using 3D Studio Max and Adobe Photoshop CC based on the literature and expert consultation method. Forty-two 45- and 59-year-old middle-aged people in Zhengzhou City, Henan Province were recruited to verify the three-dimensional body image stimuli. Through questionnaire survey and physical examination, the coincidence between the selected body type and the actual body type was tested; the body composition was measured by dual-energy absorptiometry (DXA), and the structure validity of the image was tested; the body size satisfaction was investigated by the body image stimuli and the standard questionnaire, and the empirical validity of the image was tested. The repeated survey was conducted 14 days after the initial survey, and three experts were invited to score the current somatotype of the subjects to test the test-retest reliability and inter-rater reliability of the body image stimuli. Pearson, Spearman, Kendall correlation and Kappa consistency analysis were used to evaluate the validity and reliability of the body image stimuli.Results:The average age of 42 subjects was 52.7 years old, including 13 males and 29 females. A group of three-dimensional body image stimuli of middle-aged men and women were developed, and each group included 8 images. 73.8% of the subjects chose the body size consistent with the actual body type, and the weighted Kappa coefficient was 0.755 ( P<0.01). The selected somatotype was positively correlated with body weight and body composition indexes such as fat content, and the Pearson correlation coefficient of construct validity was 0.623-0.717 ( P<0.05). The results of the two surveys were positively correlated, and the Spearman correlation coefficient of test-retest reliability was 0.784-0.821 ( P<0.05). The scores of the three experts on the current somatotype of the subjects were positively correlated, and the Kendall correlation coefficient of inter-rater reliability was 0.818-0.878 ( P<0.05). Conclusion:The development of principle and reference basis of three-dimensional body image stimuli of middle-aged people is reliable, and the validity and reliability of the body image stimuli are good.
