Chinese Journal of Ultrasonography 2009;18(9):780-782
Objective To assess the ability of the new software SonoAVC to measure follicular volume and to compare these volume calculations with those made by conventional methods. Methods Three-dimensional ultrasound imaging was used to acquire volumetric data from the ovaries of 50 women undergoing controlled ovarian stimulation as part of in-vitro fertilization treatment. SonoAVC was used to automatically measure the volume of follicles and virtual organ computer-aided analysis(VOCAL) was also applied to measure volume, which was used as the standard of volume measurement. And the three perpendicular diameters (xyz diameters) of follicles were manually measured by conventional two-dimensional(2D) ultrasound, which were used to estimate volume using the sphere formula. And the validity of each technique was compared using limits of agreement. Results One hundred and seventy-six follicles were studied. SonoAVC and VOCAL provided highly accurate and repeatable follicular volume measurements in all cases. Volumes estimated from manually derived follicular diameter measurements were less accurate and repeatable. VOCAL took more time in follicular volume of measurement than SonoAVC and conventional 2D displays. Conclusions SonoAVC provides highly accurate, repeatable,and efficient measurements of follicular volume.

Objective To investigate the prevalence of renal insufficiency and its associated factors in type 2 diabetes mellitus with normoalbuminuria using estimated glomerular filtration rate ( eGFR) .Methods We retrospectively analyzed 10-year data of chronic complications in type 2 diabetics in-patient from the Chinese Diabetes Society.eGFR was estimated using the equation from Modification of Diet in Renal Disease(MDRD) study.The clinical characteristics as well as associated factors for low eGFR were analyzed among the normoalbuminuric type 2 diabetic patients.Results A total of 1351 type 2 diabetic patients were included, 755 patients with normoalbuminuria, 466 patients with microalbuminuria and 130 patients with macroalbuminuria respectively.Among the patients, 310 (22.9% ) had low eGFR (GFR <60 ml · min~(-1) · 1.73 m~(-2) ) , 19.7% (149/755) in the patients with normoalbuminuria, 21.9% (102/466) in microalbuminuria and 45.4% ( 59/130 ) in macroalbuminuria Patients with normoalbuminuria and low eGFR suffered more chronic complications than those with normoalbuminuria and normal eGFR, mainly retinopathy, cerebrovascular diseases and sensory neuropathy.Stepwise logistic regression analysis revealed that age ( OR = 1.042, P < 0.001), diabetic duration ( OR = 1.038, P = 0.045), systolic blood pressure (OR = 1.017, P < 0.001) were independently associated with renal impairment among the patients with normoalbuminuria.Body mass index ( OR = 0.868, P < 0.001) and HbAlc (OR =0.898, P =0.021) were also related with renal insufficiency.Conclusion A considerable proportion in type 2 diabetic patients without albuminuria may exist renal impairment, and eGFR estimation could benefit the evaluation of renal function in such patients.

Objective To investigate the association of transforming growth factor (TGF) gene rs1800469 (TGF1-509C/T) and rs1982073 (TGF1+869T/C) single nucleotide polymorphisms (SNP) with susceptibility of lung cancer. Methods The case group consisted of 193 histologically diagnosed lung cancer patients, and control group of 211 controls were selected from cancer-free patients at the same time. The single nucleotide polymorphisms of rs1800469 (TGF1-509C/T) and rs1982073(TGF1+869T/C) were analyzed by real-time fluorescent quantitative reverse transcription polymerase chain reaction method. The demographic characteristics, correlated risk factors of exposure and SNP between 2 groups were compared. Results The genotype distribution frequency of TGF1+869T/C and TGF1-509C/T in control group was accorded with Hardy-Weinberg law (P>0.05). The TT, TC and CC genotype distribution frequency in TGF1+869T/C in case group were 16.1%(31/193), 55.4%(107/193) and 28.5%(55/193), while these in control group were 22.3% (47/211), 50.2% (106/211) and 27.5% (58/211), and there were no statistical differences (P>0.05). The TT, TC and CC genotype distribution frequency in TGF1-509C/T in case group were 28.0%(54/193), 56.0%(108/193) and 16.1%(31/193), while these in control group were 27.0% (57/211), 51.2% (108/211) and 21.8% (46/211), and there were no statistical differences (P>0.05). The allele in rs1800469 (TGF1-509C/T) and rs1982073 (TGF1+869T/C) showed no association with lung cancer (P>0.05). Conclusions TGF gene SNP may not be associated with susceptibility to lung cancer in Han Chinese in North China.

Objective: To quantitatively study the incidental extra-cardiac ifndings (ECFs) by coronary computed tomography angiography (CCTA) in patients with suspected coronary artery disease (CAD) in order to better recognize those lesions in clinical practice.
Methods: A total of 1169 suspected CAD patients received CCTA in our hospital from 2011-06 to 2013-03 and 1030 patients were enrolled in this study. There were 589 in-patients, 441 out-patients and 549 patients≥60 years of age,481 patients < 60 years of age. 3 physicians evaluated the incidental ECFs in the full ifeld of view (FOV) in different window level and window width for lung, mediastinum, thorax and upper abdominal areas. Clinical relevance of ECFs were classiifed by corresponding scores. Score 1, the patients with severe lesion need immediate treatment, score 2, the lesion with clinical and prognostic signiifcance and score 3, the ifnding without clinical signiifcance.
Results: There were 197/1030 (19.1%) patients having 224 ECFs and 27 (2.6%) patients having 2 ECFs; 90/1030 (8.7%) patients having 106 signiifcant lesions including 3 (0.3%) of lung cancer and 8 (0.8%) of pulmonary embolism; 107 patients with 118 lesions without signiifcance. ECFs were found in 114/589 (19.4%) in-patients and in 83/441 (18.8%) out-patients, P>0.05; 76/481 (15.8%) of patients < 60 years of age and 121/549 (22.0%) of patients≥60 years,P<0.05.
Conclusion: Unexpected ECFs detection rate was 19.1% in patients undergoing CCTA without further radiation exposure by reconstruction with the full FOV setting, and 8.7% of ECFs had clinical signiifcance. Radiologists should routinely analyze the extra-cardiac organs in CCTA.

Purpose To explore the correlation between fetal cardiac function and interventricular septal thickness in fetuses of gestational diabetes mellitus (GDM) mothers. Materials and Methods Thirty-nine GDM mothers were involved in the study and divided into group MH (fetuses of GDM mothers with interventricular septal hypertrophy) and group NMH (fetuses of GDM mothers with normal interventricular septal thickness). Ultrasonic cardiogram was performed for both groups to assess such variables as interventricular septum thickness at end diastole (IVSd), left ventricular ejection fraction (LVEF), left ventricular fraction shortening (LVFS), right ventricular fraction shortening (RVFS), the ratio of E and A of mitral flow (E/AMV), the ratio of E and A of tricuspid flow (E/ATV), peak velocity of aortic valve (VPAO), peak velocity of pulmonary valve (VPPA) and myocardial performance index (MPI). The results were further compared with those of control group. Results The VPAO, VPPA, LVEF and LVFS in group NMH were significantly higher than those in control group (P<0.05). The VPAO, VPPA, LVEF, LVFS and RVFS in group MH were significantly higher than those in control group whilst the E/AMV and E/ATV significantly lower than those in control group (P<0.05). The LVEF, LVFS and RVFS in group MH were significantly higher than those in group NMH whilst the E/AMV and E/ATV significantly lower (P<0.05). MPI in group MH was significantly higher than that in group NMH (P<0.05), whilst both were significantly higher than that in control group (P<0.05). The LVEF, LVFS, RVFS, VPAO and VPPA were positively correlated with IVSd (r=0.48, 0.51, 0.45, 0.30, 0.30;P<0.05). Conclusion Cardiac function in fetuses of GDM mothers may be associated with interventricular septal thickness.
