ABSTRACT

【Objective】 To analyze the composition of urinary calculi in Longnan, Gansu province, and the relationship between the composition and clinical characteristics of patients, so as to provide reference for the prevention and treatment of this disease. 【Methods】 The composition of 500 cases of urinary calculi hospitalized in our department during Apr. 2021 and Feb.2023 were analyzed using the infrared spectrum stone composition analyzer. The clinical characteristics of the patients were evaluated and analyzed. 【Results】 The male-to-female ration of patients was 2.70∶1. Most patients aged 21 to 60 years (437, 87.4%). Most cases were ureteral calculi (72.8%), followed by renal calculi (22.2%), and bladder calculi (5.0%). There were 166 cases of calcium oxalate calculi, 293 cases of calcium oxalate + carbonated apatite calculi, 24 cases of calcium oxalate + carbonated apatite + hydroxyl apatite calculi, 4 cases of calcium oxalate + calcium bicarbonate calculi, 7 cases of urate calculi, 6 cases of carbonated apatite + struvite calculi. Oxalate calculi were the most common in all age groups, and urate calculi were the most common in the 21 to 40 age group. Calcium oxalate calculi were most common in the ureter (127, 76.5%), significantly higher than in other sites (χ2=3.222, P=0.020). Calcium oxalate + calcium hydrogen phosphate calculi was the least common in the bladder, significantly different from the other parts (χ2=2.092, P=0.037). Magnesium ammonium phosphate hexahydrate and/or calcium carbonate or calcium oxalate calculi were the most common in the kidney (50.0%), significantly different from the other parts (χ2=9.448, P=0.007). 【Conclusion】 In Longnan area, the incidence of urinary calculi is significantly higher in male than in female. Ureteral calculi are mainly composed of calcium oxalate + carbonated apatite and calcium oxalate. According to different risk factors, individual prevention programs should be developed.

ABSTRACT

Objective:To evaluate the reliability and validity of Short-form health survey-36 (SF-36) during the first trimester of pregnancy.Methods:From January 2020 to January 2021, pregnant women aged 18―40 during the first trimester visit were admitted to the Obstetric Department of Beijing Obstetrics and Gynecology Hospital, Capital Medical University. Split-half reliability and Cronbach′s α coefficients were used to evaluate the reliability. The convergent and discriminative validity were evaluated by using AMOS 24.0 and the criterion-rated validity was evaluated with correlation analysis and non-parameter test. Exploratory factor analysis and confirmatory factor analysis based on structural equation modeling were used in the evaluation of contract validity.Results:SF-36 scale had good reliability (split-half reliability: R=0.901, Cronbach′s α coefficients=0.878), convergent validity, discriminate validity and the criterion-rated validity ( r=0.907). Second-order confirmatory factor analysis model was not well-fitted ( RMSEA=0.070, χ 2/dF=3.566, GFI=0.813, CFI=0.814, TLI=0.792, NFI=0.761), indicating that the construct validity was poor. Conclusions:The reliability, consolidation validity, discrimination validity and criterion-related validity of Sf-36 scale are good, while the construct validity is poor. Improvement is needed when the scale is used for pregnant women.
