RESUMEN
Objective:To collect data on urinary flow rate in the elderly female population across the country and to analyze the range of reference values.Methods:This study enrolled 333 subjects from July 2020 to June 2022.The study implementation process was divided into two steps.In the first step, subjects completed an electronic questionnaire, which included basic information about the subject, a short form for urinary incontinence, and a scoring form for the symptoms of overactive bladder syndrome.In the second step, the staff introduced the use of a mobile uroflowmetric device and distributed the instrument and materials.Uroflow rate data were automatically uploaded to a cloud database via the mobile phone.Subsequently, two or more physicians specializing in urinary control performed Uroflow rate-qualifying screenings and conducted statistical analyses.Results:A total of 333 subjects were enrolled in the study, and the researchers collected 1375 qualified urine flow rate records using a mobile urine flow rate instrument.The age of the subjects ranged from 60 to 84 years, with a mean age of 69 years.The reference ranges for urinary flow rate were found to be 24.8-26.2 s, with a mean urinary flow rate of 12.2-12.9 ml/s, a maximum urinary flow rate of 22.2-23.4 ml/s, and a time to peak of 8.5-9.7 s. The study observed a tendency for both maximal and mean urinary flow rates to decrease in older women as their age increased(Pearson correlation coefficient: -0.1, P<0.001). Conclusions:The uroflow rate of older women decreases with aging.Specifically, the average uroflow rate of women over 80 years old is lower than that of other age groups.This study aims to establish normal uroflow parameters for uroflowmetry in healthy older women in China.
RESUMEN
In order to search for new antiplatelet agents with higher potency, a series of tetramethylpyrazine ( TMP) /chalcone hybrids ( 2-26) were synthesized and evaluated based on the principle of bioisostere and hybrid-ization. They exerted inhibitory activity against adenosine diphosphate ( ADP )-induced and arachidonic acid ( AA)-induced platelet aggregation to varied extent. Among them, compound 8 was the most potent with IC50 of 0. 14 mmol/L on ADP-induced platelet aggregation ( 9. 1 folds of TMP and 10. 5 folds of chalcone ) and 0. 09 mmol/L on AA-induced platelet aggregation ( 8. 8 folds of TMP and 10. 0 folds of chalcone) , which was superior to clinically used anti-platelet drug aspirin ( ASP, IC50 =0. 15 mmol/L) .
RESUMEN
Objective:To study the effects on lymphocyte & T subset of SARS patients treated by integrative traditional Chinese and western medicine(ICWM). Methods:48 patients were randomly divided into two groups, the control group treated by western medicine (WM) alone and the test group treated by ICWM. The test group patients took the traditional Chinese medicine by 3 weeks based on their conditions. Lymphocyte and T subset were measured. Results:① At pretreatment, absolute value of lymphocyte of 38 patients in all patients were low. There were 19 patients with lowered CD3 +, and 28 patients with lowered CD4 +/CD8 + ratio in 38 patients with T subset measured. ② The value of lymphocyte in plasma in patients after ICWM treatment increased from 1 00?10 9?0 46?10 9 L -1 to 1 92?10 9?0 74?10 9 L -1 ( P
