Objective: To investigate the relationship between blood pressure variability and ambulatory arterial stiffness index (AASI) in both normal subjects and hypertensive patients.
Methods: A total of 280 consecutive subjects without antihypertensive medication were studied. All subjects received ambulatory blood pressure monitoring (ABPM) and AASI was calculated as 1 minus the regression slope of diastolic blood pressure value vs systolic blood pressure value according to ABPM recording.
Results: ① There were 161 subjects with male gender, 138 patients with hypertension, and the average age was (50.4 ± 13.3) years.②Pearson analysis indicated that AASI was related to age (r=0.272, P<0.001), 24-hour mean pulse pressure (r=0.504, P<0.001) , nocturnal diastolic blood pressure dipping (r=-0.334, P<0.001) and standard deviation of 24-hour diastolic blood pressure (r=-0.520, P<0.001).③AASI in anti-dipper hypertensive patients was higher than that in dipper patients, P<0.05;while AASI between dipper and non-dipper patients, dipper and extreme-dipper patients were similar, P>0.05 respectively.④Multiple linear regression analysis demonstrated that with adjusted age, gender, BMI and blood pressure, AASI was independently related to 24-hour mean pulse pressure (β=0.003, P<0.001), nocturnal diastolic blood pressure dipping (β=-0.001, P<0.05), standard deviations of 24-hour systolic blood pressure (β=0.032, P<0.001) and 24-hour diastolic blood pressure (β=-0.064, P<0.001), standard deviation of 24-hour heart rate (β=0.006, P<0.001).
Conclusion:AASI is closely related to blood pressure variability, it’s a comprehensive index for arterial stiffness and blood pressure variability.

Retinal vasculopathy with cerebral leukoencephalopathy and systemic manifestations (RVCL-S) is a rare hereditary cerebrovascular disease. The clinical presentations are characterized by early-onset visual impairment, liver and kidney dysfunction and neurological symptoms. Imaging examinations are often misdiagnosed as neoplasms or tumefactive multiple sclerosis for invasive examination. Early and correct identification is essential for optimizing treatment strategies and comprehensive management. This review is to improve the understanding of RVCL-S, which may help to reach more accurate diagnosis and better treatment, and improve further research.

Objective:To analyze the clinical and laboratory features of patients with Coronavirus Disease 2019(COVID-19), for providing reference for the diagnosis and treatment of the disease.Methods:The clinical data of 72 patients confirmed as COVID-19 in Qishan hospital during January 23, 2020 to February 13, 2020 were collected. The data included the general information, clinical manifestations, laboratory tests and CT findings of the lungs. According to the severity of the disease, the patients were divided into the non-severe group and the severe group, and the laboratory tests characteristics of the two groups were compared. SPSS 22.0 statistical software was used for data analysis.Results:In the 72 patients, 40 were males and 32 females, the average age was (46.0±14.8) years. The main clinical manifestations were fever (84.7%) and cough (77.8%). Among them, 45 cases (62.5%) had expectoration with a small amount of white sticky sputum. The main laboratory results showed that lymphocyte count decreased in 26 cases (36.1%), the absolute number of T lymphocytes decreased in 18 cases (25.0%), CD4 + T cell count decreased in 8 cases (11.1%), CD8 + T cell count decreased in 14 cases (19.4%), ESR increased in 42 cases (58.3%), and CRP increased in 31 cases (43.1%). Peripheral blood lymphocyte (L), albumin, CD4 + T cell, CD8 + T cell, T-lymphocyte in severe group (n=61) were lower than those in non-severe group (n=11), while C-reactive protein (CRP), serum amyloid A (SAA), erythrocyte sedimentation rate (ESR), fibrin (FIB), aspartate aminotransferase (AST), creatine kinase (CK), lactate dehydrogenase (LDH) in severe group were higher than those in non-severe group ( P<0.05). In 72 patients, the negative time of the twice nucleic acid detection from nasopharyngeal swabs and sputum specimens were (21.48±7.9) days and (27.79±7.4) days, there were significant differences between the two groups of specimens for two consecutive negative times ( t=-4.532, P=0.000). The main pulmonary imaging manifestations of COVID-19 patients: two lungs in 58 cases, patchy opacities in 51 cases and ground glass shadows in 61 cases. Conclusions:Most of the COVID-19 patients in Yantai and Weihai were common type. The abnormal T lymphocyte, subcohorte and other laboratory indicators may indicate that the patients are more serious.

Objective:To construct a scientific research performance evaluation index system for specialized hospitals based on disciplinary development.Methods:Building a preliminary evaluation index framework of scientific research performance through literature review and expert consultation meetings, combined with the strategic goals of strengthening specialization and weakening generalization; Delphi method was adopted to conduct two rounds questionnaires survey to collect the importance scores for each index, which confirmed the content of the index system; finally, applied the analytic hierarchy process to calculate the weight coefficient of each index.Results:The responding rates of the two rounds questionnaire survey reached 95%, and the authoritative coefficients were 0.75 and 0.76, respectively. The research results were reliable. The coordination coefficients of all levels of the two surveys were greater than 0.1, according to the significance testing, the P values were less than 0.05, and the expert opinions were well coordinated. Finally, we developed a three-level scientific research performance evaluation system under the guidance of disciplinary development, which including 3 first-level indicators, 20 second-level indicators, as well as 56 third-level indicators. Conclusions:A scientific research performance evaluation system was constructed based on scientific theories. This system combined relevant indicators, such as the development of special disciplinary of specialized hospitals with scientific validity and operability.
