Vitamin E succinate (VES) has been recently recognized as a neotype tumor suppressor.However, the molecular mechanisms that VES induces apoptosis in breast cancer cells have not been validated. Current studies have indicated that VES induces breast cancer cell apoptosis through TGF-β signaling transduction pathways, Fas signaling transduction pathways, and JNK signaling transduction pathways.Other signaling transduction pathways still need to be investigated further.

Objective To describe the current status of adult overweight and obesity in urban and suburb areas of Tianjin.Methods 2 283 adult people including 1 131 from urban and 1 152 from suburb were selected by multi-stage cluster random sampling.The waist circumference,weight and height of the subjects were measured.Then the BMI was calculated.Results The mean BMI of adult people in Tianjin was 25.05?5.02 kg/m2,the overweight rate was 36.9%,the obesity rate was 20.0% and the abdominal obesity rate was 63.9%.The prevalent rates of overweight,obesity and abdominal obesity in different age groups showed significant differences.The rates of overweight,obesity and abdominal obesity increased with ages in urban area.The overweight rate in 40～49 yrs and the obesity rate in 50～59 yrs reached their peak values in suburb.Besides the overweight rate in urban was significantly higher,the obesity rate and abdominal obesity rate were no significant differences between urban and suburb.The prevalent rates of overweight,obesity and abdominal obesity showed no significant differences between the adult male and female in Tianjin,but the prevalent rates of obesity and abdominal obesity in female were significantly higher than those in male in the suburb.The prevalence of obesity in the middle-ages showed significant differences between different occupational population,the retired taking the highest while the workers taking the lowest value.The prevalence of obesity showed no significant differences between population with different education background and different income situation.Conclusion The rates of adult overweight and obesity in Tianjin were higher than those of all over the country in 2002,and the abdomen obesity reached to 63.9%.Intervention should be taken to change this situation as soon as possible.

Objective To investigate the application of statins in secondary prevention of ischemic stroke and transient ischemic attacks (TIA) in different risk groups,and to identify the factors influencing the compliance of statins. Methods Data were prospectively collected on consecutively encountered ischemic stroke or TIA patients admitted to the First Affiliated Hospital of Zhengzhou University from April 2009 to January 2010.All clinical characteristics and possible factors influencing the compliance of statins were collected; the application of statins was investigated at 3-month follow-up.The multivariate Logistic regression analysis was used for the analysis of influence factors of the compliance of statins.Results All 369 patients were collected,52.8％ of cases were prescribed statins for therapy during hospitalization.The application rate of statins in accordance with guidelines in high-risk group,extremely high-risk Ⅱ group and extremely high-risk Ⅰ group was 25.0％ (16/64),44.1％ (30/68) and 71.4％ (135/189),respectively. Logistic regression analysis showed that the statins application during hospitalization was associated with diabetes history ( P =0.032,OR =1.789,95％ CI 1.052-3.043 ) and the presence of carotid vulnerable plaques(P =0.000,OR =5.308,95％ CI 3.340-8.434).The general application rate of statins was 22.3％ (81/363),which was significantly lower than that during hospitalization. The application rate of statins in accordance with guidelines in high-risk group,extremely high-risk Ⅱ group and extremely high-risk Ⅰ group was 9.7％ ( 6/62 ),25.8％ (17/66) and 29.4％ (55/187) respectively.Logistic regression analysis showed that good compliance of statins was associated with discharge instructions on statins application ( P =0.000,OR =34.852,95％ CI 14.673-175.452 ). Conclusions The compliance of statins in secondary prevention of ischemic stroke and TIA is poor,and there is still a large gap between clinical practice and guidelines; Discharge instructions on statins application increase the compliance of statins.

Objective To investigate the effect of the side of cerebral lesion on the outcome in patients with ischemic stroke.Methods A total of 407 consecutive anterior circulation ischemic stroke patients within 14 days after symptom onset were recruited prospectively.The basic data ofthe e,~ISes were collected,such as the National Institutes ofHealth Stroke Scale (NU-ISS)and the side ofcerebral lesion.The modified Rankin Scale(mRS)was used to evaluate the prognosis of the patients at 6 raomhs.Results Of the 407 patients recruited,230 patients (56.5%)Were left hemisphere stroke,177(43.5%)were fight hemisphere stroke.After multivariable logistic recession analysis,the age(odds ratio[OR]1.022,95% confidence interval[CI]1.001-1.043,P=0.040),the side of lesion(OR 1.999.95%CI1.179.3.389.P=0.010),the time from onset to admission(OR1.006,95%(7/1.002-1.010,P=0.007),the outcome of the anterior circulation ischcmic stroke at 6 months aftel"onset.The outcome of the right hemisphere stroke Was significantly worse than that of the left hemisphere stroke.The onset-admission time in patients with right hemisphere stroke(median 12 h,median 39.61 h)was significantly delayed compared to the patients with left hemisphere stroke(median 12 h,median 22.72 h;Z=-2.962,P=0.003).Condusions The outcome of the left hemisphere stroke at 6 months after onset is superior to the right hemisphere stroke,and it mau be associated with the delayed admission.

Objective To evaluate the guidance value of VKORC1 and CYP2C9 gene polymorphism on clinical application of warfarin in patients with non-valvular atrial fibrillation (NVAF). Methods A total of 290 cases of patients with NVAF were identified and their baseline data , initial dose of warfarin and base INR measurement results were recorded, then the follow-up was conducted. The initial administration of warfarin to INR standard time for the first time, total amount of warfarin and the average daily amount were recorded. All participants′ venous blood was extracted for VKORC1 and CYP2C9 gene polymorphism test. Results VKORC1 AG/GG genotype patients had longer INR standard time and higer amount of warfarin than patients with AA (103.38 ± 65.29)g vs. (53.26 ± 24.02)g, P < 0.05. Patients with type CYP2C9 gene mutation had shortest INR standard time(9.10 ± 2.01)d vs. (13.07 ± 4.28)d, P < 0.05. and lowest administration amount of warfarin (28.80 ± 17.35)g vs. (55.45 ± 23.67)g, P < 0.05. Conclusion There exist significant differences of first adminstration amount of warfarin in patients with NVAF to INR standards. Warfarin dose for VKORC1 AA genotype patients is lower than that for GG/AG type; there is short INR standard time and less adminstration amount of warfarin for CYP2C9 genotypes AC/CC patients.

To investigate the clinical manifestations and imaging characteristics of patients with different types of infectious sacroiliitis. Clinical data of 40 patients diagnosed with infectious sacroiliitis were retrospectively analyzed. Among the 40 patients, 16 patients were diagnosed as non-brucellar and non-tuberculous infectious sacroiliitis (ISI), 13 with tuberculous infectious sacroiliitis (TSI), and 11 with brucellar sacroiliitis (BSI). In the ISI and TSI group, female patients accounted for 11/16, 12/13, while the proportion of unilateral involvement was 15/16 and 12/13, respectively. Compared with ISI and TSI group, BSI patients were mainly male (8/11) and presented more bilateral involvement (6/11) ( P<0.05). Bone erosion was more common in ISI and TSI groups than in BSI group (6/15, 7/11 and 2/10), as well as abscess formation (3/15, 4/11 and 1/10, respectively). Symptoms in all patients relieved 1-2 weeks after administration of antibiotics or anti-tuberculosis treatment, but the resolution of the magnetic resonance imaging findings delayed about 6 (3-9) months. ISI and TSI patients with infectious sacroiliitis should be differentiated from spondyloarthritis, with a characteristic of more female patients, unilateral sacroiliitis, bone erosion, soft tissue involvement and abscess formation. However, BSI patients are mainly male, more bilateral involvement and less bone destruction and abscess formation. Antibiotic therapy demonstrates significant therapeutic effects, but resolution of the magnetic resonance imaging findings responses late.

Objective To assess the influence of active movement of the affected upper limb on the prognosis for patients after acute cerebral infarction.Methods From 2007 to 2008, 171 consecutive patients with acute cerebral infarction were registered prospectively in this study. Active movement of the hemiplegic upper limb was assessed on the 14th day after stroke onset. Ability in the activities of daily living was assessed using the Barthel index one year later.Results Finger flexion and extension on the 14th day after stroke onset correlated positively with Barthel index scores 1 year later. NIHSS scores at admission, the time interval from onset to admission and stroke history were significant predictors of the prognosis 1 year later.Conclusion Assessing the active movement of the hemiplegic upper limb on the 14th day after stroke has good predictive power for the prognosis of acute cerebral infarction patients.

Objective:To discuss the influence of ALDH1+and CD133+phenotypic breast cancer stem-like cells in TA2 triple negative breast cancer on promoting epithelial-mesenchymal transition (EMT) occurrence in TA2 mice with triple-negative breast cancer and on their biological behavior. Methods:Flow cytometry was performed to analyze the markers ALDH1 and CD133 in TA2 mice triple nega-tive breast cancer and breast cancer stem-like cells with ALDH1+, ALDH1?, CD133+, and CD133?phenotypes, which were sorted out. Then, the TA2 mice were inoculated with sorted tumor cells according to cell type. The mice were divided into ALDH1+, ALDH1?, CD133+, and CD133-groups. The tumor-growing conditions were observed. A tumor tissue was sliced for the immunohistochemical testing of ALDH1?, CD133?, and EMT-related Twist1, E-cadherin, and VE-cadherin proteins. The expression difference of breast cancer stem cell surface markers ALDH1 and CD133 in triple-negative breast cancer and EMT-related proteins Twist1, E-cadherin, and VE-cad-herin was analyzed. Results:The expression rates of breast cancer stem cell markers ALDH1 and CD133 in TA2 mice triple negative breast cancer were 31.2%and 6.5%, respectively. The tumor growth ability of TA2 mice from ALDH1+group was obviously stronger than that from ALDH1?group. The CD133+group was evidently stronger than CD133?group. The immunohistochemical results showed that ALDH1, Twist1, and VE-cadherin expression levels in the ALDH1+group were evidently higher than that in the ALDH1?group (all P<0.05). E-cadherin expression decreased (P<0.05). CD133?, Twist1, and VE-cadherin expression levels in CD133+group were higher than that in CD133?group (all P<0.05). Conclusion:In TA2 mice triple negative breast cancer, ALDH1+and CD133+phenotypic breast cancer stem-like cells may influence the expression of EMT-related proteins, and promote the formation of triple-negative breast cancer.

Objective:To explore the experience of teachers from Guangdong and Macao in nursing teaching cooperation, the existing problems in current teaching cooperation and suggestions for improvement.Methods:From January to April 2021, using descriptive qualitative method to conduct in-depth among eight clinical tutors from The Third Affiliated Hospital of Guangzhou Medical University who teach Macao nursing students, and four teachers from Kiang Wu Nursing College of Macao using the purposive sampling method. And adopted content analysis for data analysis.Results:A total of 4 themes and 2 sub-themes were analyzed: the positive impact of cross-border teaching cooperation projects including developed the nursing business of the two places and deepened the cooperative relationship between the two places; limiting the depth and breadth of knowledge transfer because of the short cross-border learning time; the imbalance between students′ abilities and teachers′ expectations; expectations for homogeneous internships for heterogeneous groups.Conclusions:Cross-border nursing teaching cooperation is an important promoter for the development of nursing education between Guangdong and Macao, but there are still deficiencies in cooperation, and it is necessary for the two places to strengthen the construction of a sharing platform for teaching resources to promote the development of nursing education in the Guangdong-Hong Kong-Macao Greater Bay Area.

Objective To investigate the pathogenic spectrum and epidemiological characteristics of acute diarrhea patients in Tianjin.Methods A total of 1 536 stool samples of diarrhea patients were collected from hospitals between 2015 and 2017.Viral nucleic acids were detected by real-time polymerase chain reaction.Selective medium was used to culture bacteria.Drug susceptibility tests were performed by Kirby-Bauer disk diffusion method recommended by the Association for Standardization of Clinical Laboratories.x2 test was used for statistical analysis.Results In the stool samples of 1 536 cases of diarrhea,one enteric bacterium was detected in 109 samples with the positive rate of 7.10％,one enterovirus was detected in 171 samples with the positive rate of 11.13％,mixed infection was detected in 20 samples with positive rate of 1.30％,including 8 samples with enteric bacterium and enterovirus and 12 samples with double enterovirus.The total detection rate of diarrhea cases was 19.53％.Norovirus,vibrio parahaemolyticus,rotavirus,Salmonella,stellate virus and sapovirus ranked the top six in the detection rate.The total detection rate curve of bacteria showed a single peak,mainly in August,while the total detection rate curve of the virus showed a double peak,which was from May to June and from November to December.The positive rate of bacteria in patients aged over 30 years old was 9.82％ (75/764),while that in those aged less than 30 years old was 5.44％ (42/772).The difference was statistically significant (x2 =10.451,P ＜ 0.01).The positive rate of viral pathogen in patients aged no less than 25 years old was 10.02％ (91/908),while that in those aged less than 25 years old was 17.83％ (112/628).The difference was statistically significant (x2 =19.755,P ＜ 0.01).Salmonella,Shigella and vibrio parahaemolyticus were resistant to ampicillin in varying degrees.Conclusions The positive rate curves of bacteria and virus are obviously different,showing a trend of "bacterial single peak and viral double peak".Bacteria mainly infect people aged over 30 years old,while the virus mainly infects people under 25 years old.The main pathogens of diarrhea are norovirus,vibrio parahaemolyticus and rotavirus.
