RESUMEN
Objective To investigate the feasibility and effect of synchronization imaging technology of 64-slice spiral CT on urography and angiography(CTUA).Methods 36 adult patients with urinary symptoms that apply for the conventional CTU were selected. Exclusion of iodine allergy,serious heart,liver and renal insufficiency,multiple myeloma,long-term diabetes,hyperthyroidism,etc.All patients were placed intravenous tube.100 mL iohexol(300 mg I/mL),divided into 40-60 mL and 35-40 mL,shall be injected respectively by interval about 25-45 min,and the corresponding injection rate was 2-2.5 mL/s and 3.5-4.0 mL/s.About 20-30 s after the second injection,scan urinary tract for a quick CTUA source image,then scan urinary tract again for a quick source image of CTU with 5 min delay.Two groups of data with reconstruction technique(including MPR,MIP,VR etc.)should be read and diagnosed independently and double-blinded by two doctors with many years'experience in CTU.They also need to evaluate the image quality of the kidneys,urinary tracts and renal vessels,and make a statistical analysis to judge whether the CTUA inspection technique was feasible and effective.Results CTUA was good at showing renal parenchyma,ureters,urinary bladder and renal vessels,and the display rate was respectively:0.83,0.916,1,0.806,by contrast,the conventional CTU was 0,0.972,1,0,accordingly.Compared with the conventional CTU,CTUA was obviously different from the CTU,especial in displaying the distinction between renal cortex and medulla,renal vessels,and CTUA was better than the conventional CTU.While in display of ureters and urinary bladder,they had no difference,both show good.Conclusion CTUA inspection technology is superior to the conventional CTU technique,and using a routine dose contrast medium with twice bolus injection and one scanning can provide information such as the kidneys,urinary tract and renal vessels.
RESUMEN
Objectives To investigate the clinical features of clomiphene citrate (CC) resisitant in patients with the polycystic ovary syndrome(PCOS). Methods A total of 145 women with PCOS were analyzed in the center for reproductive medicine of our hospital. According to the responses to CC ,patients were divided into two groups:(1)the CC resistant group(n = 32),(2)the CC response group(n = 113). The clinical features were compared between these two groups. Results (1)Body weight,body mass index(BMI),blood pressure and F?G scores were significantly higher in the CC resistant group than those in the CC response group (P < 0.05, respectively).(2)Basic antral follicle counts(AFC),C reaction protein(CRP),fasting insulin(FI)and HOMA?IR in the CC resistant group were significantly higher than those in the CC response group (P < 0.05, respectively),however,no significant difference was observed in sex hormones between these two groups. Conclusion PCOS patients with CC resistant are more likely to have higher body weight,BMI,blood pressure, insulin resistant?indexes and basic AFC ,the clinical doctors should consider these features before the treatment of ovulation induction.
