Objective To analyze the relationship of the total length of coronary stent and patients’postoperative quality of life. Methods A number of 280 patients who were diagnosed as coronary artery by coronary angiography and successfully completed PCI surgery in our hospital from April 2012 to March 2013 were retrospectively collected.And they were divided into 3 groups according to the total length of the coronary stent,namely:group Ⅰ (68 cases,length of the coronary stent were less than 36 mm),group Ⅱ (156 cases,length of the coronary stent were 36 ~72 mm),and group Ⅲ (56 cases,length of the coronary stent were more than 72 mm).The prognosis and quality of life of patients of the 3 groups were compared.Results There was no significant difference in terms of in-stent restenosis,angina recurrence and target vessel revascularization rates among the 3 groups within 6 months after PCI surgery (P >0.05).But the incidence rate of adverse cardiac events of the 3 groups were significant different,and group Ⅲ were significantly higher than group Ⅱ,group Ⅱwas significantly high-er than in group Ⅰ (P <0.05).It was significant different in terms of the total length of coronary stent aomng the 3 groups (P <0.01).But there was no statistically significant difference in patients’quality of life among the 3 groups (P >0.05).Conclusion Although the total length of coronary stent and patients’postoperative quality of life were of no correlation,it is still recommend to make assessment of vascular lesions carefully before surgery.For patients with stable disease,it is recommend to take conservative medication treatment.Make stent implan-tation only when it’s necessary and the length of coronary stent should be strictly controlled so as to reduce the incidence of adverse cardiac events.

Objective To investigate the application value of functional exercise pathway in enhanced recovery of patients undergoing hepatectomy.Methods Fifty primary hepatic carcinoma patients who had undergone liver resection in Anhui Province Hospital from December 2014 to August 2015 were randomly divided into experimental group (n =25) and control group (n =25).Postoperative length of hospital stay,hospitalization charges,complications,postoperative pain score,postoperative ambulation and intestinal ventilation time were compared between these groups.Measurement data with normal distribution were represented as ((x) ± s) and comprison between groups was analyzed using the t test.Comparisons of count data were analyzed by the x2 test.Results Postoperative length of hospital stay of the experimental group [(7.00 ± 2.27) days] were shorter than control group [(9.36 ± 4.58) days] (t =3.090,P =0.003),and hospitalization expense was lower in the experimental group [(28 184.57 ± 8 675.65) yuan] (t =2.281,P =0.025).Compared with control group (40％),the experimental group (20％) had lower overall complication incidence (t =4.286,P =4.286),and general complications incidence (8％) is lower than that in control group (24％),however,the incidence of operation characteristic complications had not statistical significance in two groups.Besides,the intestinal recovery time in the experimental group was shorter than control group (experimental group 36.56 hours,control group 45.24 hours,t =2.390,P =0.019).Conclusion The application of functional exercise pathway in postoperative enhanced recovery exercise of patients undergoing hepatectomy is safe and effective,which can reduce the patients' postoperative hospital stay,hospital costs,and the general incidence of complications incidence,and be helpful for the intestinal function recovery.

Juxta-papillary duodenal diverticula (JPD) may easily cause biliary and pancreatic diseases. JPD changes papillary position and shape and increases the difficulties in endoscopic retrograde cholangiopancreatography (ERCP) intubation and stone removal, and it may also cause a series of complications. With reference to related articles in China and foreign countries, this article briefly describes the typing and development of JPD and its association with biliary and pancreatic diseases, analyzes the influence of common bile duct stones and JPD on ERCP, and summarizes related coping strategies, in order to provide suggestions and bases for clinical diagnosis and treatment.

Objective: To assess the application value of CT scanning in percutaneous pulmonary valve implantation (PPVI). Methods: A total of 19 patients with severe pulmonary regurgitation planed to receive PPVI in our hospital from 2014-05 to 2016-07 were studied. CT scan and transthoracic echocardiography (TTE) were conducted to collect the data of pulmonary root anatomy and to compare the difference of pulmonary annulus size measured by CT and TTE. The accuracy of pre-operative measurement was evaluated by the follow-up study at (1-26) months after the operation. Results: In all 19 patients, the mean anatomic measurements by CT were as follows: diameter of pulmonary annulus (24.3±3.5) mm, diameter of pulmonary sinotubular junction (25.4±4.0) mm, diameter at distal of main pulmonary artery (27.5±4.8) mm, diameter of right ventricular outflow tract (36.8±7.3) mm, length of main pulmonary artery (45.5±7.0) mm, diameter of left pulmonary artery (17.9±1.5) mm and diameter of right pulmonary artery (18.5±3.6) mm. The diameter of pulmonary annulus measured by CT was larger than TTE, P<0.05. During (1-26) months follow-up period, no patients suffered from stent fracture or translocation, peri-pulmonary valve regurgitation, obvious pulmonary regurgitation or coronary stenosis; 1 patient had increased flow rate at right pulmonary artery opening by stent blocking and 2 patients had residue mild stenosis of pulmonary valve. Conclusion: Pulmonary annulus size measured by CT and TTE was different; CT may precisely assess the morphology of pulmonary root with adjacent area which is important for pre-operative evaluation in PPVI patients.

Objective: To uncover the underlying mechanisms of action of the Yinlai decoction on high-calorie diet-induced pneumonia through proteomics analysis. Methods: Based on the Gene Expression Omnibus (GEO) database, lung tissue samples from normal and high-fat diet (HFD) fed mice in the GSE16377 dataset were selected as test cohorts to identify differentially expressed genes and conduct bioinformatics analyses. In the animal experiments, mice were randomly divided into the control (N), high-calorie diet pneumonia (M), and Yinlai decoction treatment (Y) groups. Mice in the M group received high-calorie feed and a 0.5 mg/mL lipopolysaccharide solution spray for 30 min for 3 d. The mice in the Y group were intragastrically administered 2 mL/10 g Yinlai decoction twice daily for 3 d. Pathological evaluation of the lung tissue was performed. Differentially expressed proteins (DEPs) in the lung tissue were identified using quantitative proteomics and bioinformatics analyses. The drug-target relationships between Yinlai decoction and core DEPs in the lung tissue were verified using AutoDock Vina and Molecular Graphics Laboratory (MGL) Tools. DEPs were verified by western blot. Results: GEO data mining showed that an HFD altered oxidative phosphorylation in mouse lung tissue. The Yinlai decoction alleviated pathological damage to lung tissue and pneumonia in mice that were fed a high-calorie diet. A total of 47 DEPs were identified between the Y and M groups. Enrichment analysis revealed their association with energy metabolism pathways such as the tricarboxylic acid cycle (TCA) and oxidative phosphorylation. The protein-protein interaction network revealed that Atp5a1, Pdha1, and Sdha were the target proteins mediating the therapeutic effects of Yinlai decoction. Molecular docking results suggested that the mechanism of the therapeutic effect of Yinlai decoction involves the binding of brassinolide, praeruptorin B, chrysoeriol, and other components in Yinlai decoction to Atp5a1. Conclusion The Yinlai decoction alleviated lung tissue damage and pneumonia in mice that were fed a high-calorie diet by regulating the TCA and oxidative phosphorylation. Our study highlights the importance of a healthy diet for patients with pneumonia and provides a scientific basis for the prevention and treatment of pneumonia through dietary adjustments.

Objective:To summarize the echocardiographic features and outcomes in fetuses with congenital ventricular outpouching (CVO).Methods:This retrospective study enrolled ten fetuses diagnosed with CVO by fetal echocardiography in the Affiliated Hospital of Qingdao University and Qingdao Women and Children's Hospital from January 2015 to April 2022. Clinical data were analyzed, including echocardiographic features, other intracardiac and extracardiac malformations, karyotypes, and pregnancy outcomes. Data were analyzed by descriptive statistics.Results:All ten cases were single, including eight ventricular diverticula and two ventricular aneurysms. Five cases had the anomaly in the left ventricular and the other five in the right. Five cases were isolated malformations, and the other five were complicated by other intra- or extracardiac malformations. A pathogenic copy number variation was detected in one case. Three pregnancies were terminated, and one was lost to follow-up. The other six fetuses were born alive and showed no obvious clinical symptoms or abnormalities in growth and development during 3-70 months of follow-up. The right ventricular diverticulum spontaneously disappeared in one case. One case with the right ventricular aneurysm was also diagnosed with noncompaction of the left ventricular myocardium by echocardiography at six months.Conclusions:Fetal CVO presents with typical echocardiographic features and can be diagnosed prenatally. Regular follow-up during pregnancy is recommended to observe the sizes of outpouchings and the occurrence of complications in fetuses with CVO after excluding other structural and chromosomal abnormalities to avoid unnecessary termination. Attention should also be paid to postnatal follow-up.

Objective:To explore any effect of regular aerobic exercise on renal fibrosis and apoptosis in rats with spontaneous hypertension.Methods:Thirty 6-week-old male spontaneously hypertensive rats were randomly divided into a sedentary group (group HS) and an exercise group (group HE). Ten age- and sex-matched Wistar-Kyoto rats formed a control group. The rats in group HE underwent 12 weeks of swimming exercise lasting 60 minutes, five times a week, while the other two groups were kept quiet in their cages. Before and after the training, the tail artery blood pressure of each rat was measured. Renal function was evaluated after the experiment by measuring 24h urine protein, blood urea nitrogen and serum creatinine levels, while the degree of renal interstitial fibrosis was measured using Masson staining and the collagen volume fraction was calculated. The number of apoptotic cells in the renal tubular epithelial tissue was recorded by TUNEL staining and the apoptosis rate was calculated. The expression of renal transforming growth factor β1 (TGF-β1), Smad2/3, Smad7, Bax and Bcl-2 protein were detected using western blotting.Results:After the intervention, the average systolic and diastolic blood pressure and mean arterial pressure of group HS had increased significantly, while those of group HE had decreased significantly, with no significant changes in those measurements among the control group. Compared with the control group, after the intervention, the average blood pressure, 24h urinary protein, blood urea nitrogen and serum creatinine, as well as the cell apoptosis rate and expression of TGF-β1, Smad2/3 and Bax had increased significantly, and that of Smad7 and Bcl-2 had decreased significantly in group HS. And compared with group HS, in group HE the average blood pressure, 24h urinary protein, blood urea nitrogen, serum creatinine and the cell apoptosis rate had decreased significantly, together with the expression of TGF-β1, Smad2/3 and Bax, but the average expression of Smad7 and Bcl-2 had increased significantly.Conclusion:Regular aerobic exercise can relieve the renal dysfunction seen in spontaneous hypertension, at least in rats, by inhibiting renal fibrosis and apoptosis.

Objective: To investigate the current status of refractive errors and insufficient hyperopia reserve in preschool children aged 3-6 years in Hefei and to analyze influencing factors, so as to provide a scientific basis for formulating targeted myopia prevention policies and comprehensive interventions. Methods: In May 2022, a stratified cluster random sampling method was used to select 897 preschool children from 8 kindergartens across four districts (Baohe, Yaohai, Shushan, and Economic and Technological Development Zone) in Hefei, and Children’s Visual Health related Behavior Assessment Scale was used to collect personal information and environmental factors. Pre and post cycloplegic refraction tests were conducted to assess insufficient hyperopic reserve and refractive development levels. Group comparisons were conducted using 2 test, t-test or analysis of variance. Multivariate regression analysis was performed to identify key factors influencing hyperopic reserve, axial length and spherical equivalent in preschool children. Results: The detection rates of refractive errors among preschool children were 6.8% for hyperopia, 1.6% for myopia, and 11.1% for astigmatism. Notably, the prevalence of myopia was significantly higher in boys (2.3%) than in girls (0.7%) ( χ 2=3.88, P <0.05). Additionally, 8.8% of the children exhibited insufficient hyperopic reserve. The results of multiple regression analysis showed that preschool children with high myopia in the father, high myopia in the mother, longer daily duration of near work, and longer daily electronic product use time had increased risks of axial growth ( β =0.12, 0.09, 0.15, 0.11), SE reduction ( β =-0.10, -0.07, -0.18, -0.13), and insufficient hyperopic reserve ( OR=1.87, 2.22, 1.40, 1.28) (P <0.05). While, preschool children with longer sleep time and daily outdoor activity duration had lower risks of axial growth ( β =-0.11, -0.10 ), SE reduction ( β =0.39, 0.51), and insufficient hyperopia reserve ( OR =0.54, 0.51) in preschool children ( P <0.05). Conclusions The rates of refractive errors and insufficient hyperopia reserve in preschool children in Hefei are relatively low, which are influenced by many factors. Parents, kindergartens and relevant departments should implement early vision monitoring and intervention for preschool children, and cultivate their scientific eye use habits.

Objective:To explore the application status and trends of the health examination data.Methods:Relevant literatures on health examination data were retrieved from Web of Science from 1 January 2007 to 30 June 2022 and China Knowledge Network Infrastructure from 1 January 1992 to 30 June 2022; and the literature and research contents were visually analyzed by using CiteSpace 6.1 bibliometrics software.Results:Total of 5 517 Chinese articles and 18 563 English articles were selected. The publication volume of health examination data in China increased year by year since 1992, and the international publication volume also showed an increasing trend. The Chinese literature focused on health management, osteoporosis, overweight, and physical examination subjects such as pilots, while the English literature focused on the study of obesity, care and functional cognition after the formation of a cohort of physical examination data. More co-citation papers related to health examination data were published in the journals from developed countries mainly in the United States and the United Kingdom, and the contents of the co-cited journals highly covered disease research on chronic diseases, such as cardiovascular disease, functional cognition and rehabilitation.Conclusions:The number of articles published on health examination data is increasing year by year, and in the future, more studies will use big data algorithms such as machine learning to measure the association between the risk of chronic diseases and related influencing factors.
