Objective To observe the surface structures of cardiovascular endothelial cells in situ with atomic force microscope (AFM). Methods Fresh aorta and aortic valve were dissected from 10 healthy male New Zealand white rabbits. Before fixed in 1% formaldehyde, the fresh tissues were washed in the buffer phosphate solution. Under general microscope, the fixed aorta or valve was spread on the double side stick tape which had already been stuck on the glass slide. The intima of aorta or the aorta side of valve was towards upside. Then the specimen was dried under 37 degrees centigrade in an attemperator and was washed with pure water. After dried again, the specimen was loaded on the platform ofNanoScope llla AFM and was scanned in tapping mode with the scanning speed of 0.5 HZ. Results The surface structures of endothelial cell on the fixed and dried tissue could be obsserved clearly in situ with AFM. Aortic endothclial cells were large, branched and arranged sparsely and parallel to the direction of blood flow, whereas endothelial cells on aorta valve surface were small, less branched and arranged intensively and vertical to the direction of blood flow. When the scanning range was dwindled, granular ultra-structures could be observed on the surface of endothelial cells, and, as the scanning range was dwindled further, fissure and convolution could be seen on the surface of granules from aortic endothelial cells. Centre cavity and surrounding swelling volcano-like structure could be seen on the surface of granules from endothelial cells of aortic valve. Conclusions It's feasible to observe the surface ultra-structures of cardiovascular endothelial cells in situ with AFM and morphological information provided by A FM might be of clinical value in future histopathological diagnosis.

Methods:
12 out of 115 communities were randomly selected in Futian district of Shenzhen city from October to November, 2013, and 1 923 cases were screened by multiple ways as high risk groups of chronic diseases. High risk groups of chronic diseases were divided into intervention group (1 338 cases, from five residential communities and three villages within city) and control group (585 cases, from four residential communities). The intervention group received group based health education activities as well as lifestyle intervention. The intervention group was provided with health management which was mainly lifestyle intervention. No intervention was implemented in the control group. All participants were followed up over two years. 1 563 participants (1 002 in intervention group and 561 in control group) were followed up from October to November, 2015. The changes of lifestyle related outcome indicators were analyzed to examine the effect of intervention.
Results:
In the intervention group, 21.8% (219 persons) in high risk groups of chronic diseases became healthy individuals and 15.2% (152 persons) became patients with chronic diseases. In the control group, 9.6% (54 persons) in high risk groups of chronic diseases became healthy individuals and 20.5% (115 persons) became patients with chronic diseases. The outcome of the intervention group was better than that of the control group and the difference was statistically significant (χ2=-5.67,

Objective:To observe the clinical effect of pelvic floor ultrasound in the diagnosis and rehabilitation training of postpartum stress urinary incontinence(SUI).Methods:From May 2017 to May 2019, 200 SUI patients and 200 healthy pregnant women in the same period admitted to the First People's Hospital of Huzhou were selected in this study.All the subjects were tested by perineum and pelvic floor ultrasound, and the patients with SUI were instructed to carry out pelvic floor muscle rehabilitation training, the level of rehabilitation training effect was evaluated, and to statistically analyze the difference of pelvic floor ultrasound parameters between the patients with SUI and the healthy women, and the patients with different levels of efficacy.Results:The results of pelvic floor ultrasound in SUI patients were significantly higher than those in healthy women( t=6.536-14.925, all P<0.05). The rate of urinary leakage in SUI patients [88.50%(177/200)] was significantly higher than that in healthy women [10.50%(21/200)](χ 2=243.384, P<0.05). The total effective rate of rehabilitation training was 79.50%(159/200). The bladder neck moving distance, urethra rotation angle, posterior angle of bladder urethra in resting state and posterior angle of bladder urethra in Valsalva state in SUI patients with ineffective rehabilitation training were significantly higher than those in SUI patients with general effective rehabilitation training( t=4.662-12.537, all P<0.05). The formation rate of urethra infundibulum in SUI patients with ineffective rehabilitation training [70.73%(29/41)] was significantly higher than that in SUI patients with effective rehabilitation training [19.50%(31/159)](χ 2=40.744, P<0.05). Conclusion:The rehabilitation training of discoid muscles can effectively relieve the related clinical symptoms of postnatal SUI patients.The detection of pelvic ultrasound has a certain clinical value in the diagnosis of postpartum SUI and evaluation of rehabilitation training effect.

Objective To evaluate the diagnostic efficacy of narrow band imaging (NBI) international colorectal endoscopic (NICE) classification in distinguishing neoplastic from non-neoplastic colorectal polyps during routine clinical practice. Methods A total of 224 lesions detected by white light colonoscopy by non-expert endoscopists were collected in this retrospective study. Each lesion was assessed by NBI and classified by NICE classification. The results were compared with pathological findings from endoscopic or surgical resected specimen. Results Among these 224 polyps, there were 59 of type 1, 159 of type 2 and 6 of type 3 according to NICE classification. There were 58 non-tumorous and 166 tumorous polyps according to pathological diagnosis. The total diagnostic sensitivity, specificity, positive predictive value, negative predictive value and accuracy of NICE classification for colorectal tumor were 91. 6%, 77. 6%, 92. 1%,76. 3%and 87. 9%, respectively.Diagnostic sensitivity and accuracy in big (>10 mm in diameter), small (>5-10 mm in diameter) and mini (≤5 mm in diameter) polyp groups were 100. 0%, 97. 0% and 80. 9%, as well as 95. 7%, 87. 8%, and 83. 3%, respectively. Diagnostic accuracy showed a decreasing tendency on polyp size, without significant difference between the three groups ( P=0. 694). Conclusion NICE classification with non-magnified NBI is effective in distinguishing neoplastic and non-neoplastic colorectal polyps by non-expert endoscopists and is potentially worth popularizing for routine clinical practice.

Objective:To compare the effects of different test meals on postprandial triglycerides and to optimize the standard meal composition and the blood sampling protocol for the oral fat tolerance test.Methods:This study is a prospective, open-label, randomized, cross-over trial. In March 2023, 36 volunteers were recruited in Hebei General Hospital. They underwent a health examination and oral glucose tolerance test. Twenty-six healthy volunteers(11 males and 15 females) were included in this study, with an average age of(39.08±4.56) years. Each volunteer received 75 g protein meal, 75 g fat meal, 700 kcal fixed-calorie high-fat mixed meal, and a high-fat mixed meal with energy adjusted based on 10 kcal/kg body weight. A one-week washout period of regular diet was applied before each trial. Blood was collected at fasting status and 1, 2, 3, 4, 5, and 6 hours after a meal to detect serum triglycerides, total cholesterol, low density lipoprotein-cholesterol(LDL-C), high density lipoprotein-cholesterol(HDL-C), glucose, and insulin. The variations of postprandial metabolic indicators over time following the consumption of different test meals were analyzed. The disparities in postprandial metabolic responses between the two types of mixed meals were compared.Results:The protein meal, fat meal, fixed-calorie high-fat mixed meal, and adjusted-calorie high-fat mixed meal resulted in postprandial triglyceride increases of 22.45%, 115.40%, 77.14%, and 63.63%, and insulin increase of 560.43%, 85.69%, 554.18%, and 598.97%, respectively, and with reductions in total cholesterol, LDL-C, and HDL-C ranging from 5.64%-21.81%, respectively. The blood glucose changed slightly. Changes in metabolic indicators mainly occured within 4 hours. The comparison of the characteristics of postprandial triglycerides between the two high-fat mixed meals showed no statistically significant differences( P>0.05). Conclusion:A standardize protocol with a 700 kcal fixed-calorie high-fat mixed meal as test meal, and blood lipid levels measured at fasting and at 1, 2, 3, and 4 hours after consumption, can serve as an optimized approach for oral fat tolerance test.

Modulating Tankyrases (TNKS), interactions with USP25 to promote TNKS degradation, rather than inhibiting their enzymatic activities, is emerging as an alternative/specific approach to inhibit the Wnt/β-catenin pathway. Here, we identified UAT-B, a novel neoantimycin analog isolated from Streptomyces conglobatus, as a small-molecule inhibitor of TNKS-USP25 protein-protein interaction (PPI) to overcome multi-drug resistance in colorectal cancer (CRC). The disruption of TNKS-USP25 complex formation by UAT-B led to a significant decrease in TNKS levels, triggering cell apoptosis through modulation of the Wnt/β-catenin pathway. Importantly, UAT-B successfully inhibited the CRC cells growth that harbored high TNKS levels, as demonstrated in various in vitro and in vivo studies utilizing cell line-based and patient-derived xenografts, as well as APCmin/+ spontaneous CRC models. Collectively, these findings suggest that targeting the TNKS-USP25 PPI using a small-molecule inhibitor represents a compelling therapeutic strategy for CRC treatment, and UAT-B emerges as a promising candidate for further preclinical and clinical investigations.
