Objective To study radiological_anatomy of greater omentum and to address the related clinical implications,and to provide anatomic data for the radiological diagnosis and surgical application of greater omentum. Methods The anatomic distribution and morphology of the greater omentum as well as the anatomic relationship of the organs in the vicinity were analyzed by using axial,coronal,sagittal and 3D images from 16_detector row spiral CT scans of 60 individuals.We assessed the advantages of these images as well as the clinical significance.The data were recorded and analyzed by using SPSS11.5 software. Results 1.Advantages of three sections: axial section,the display of the fatty tissue and the anatomic distribution;coronal section,the vasculature; sagittal section,the anatomic relationship of neighbour organs.2.Three_dimensional reformatted images showed the return of the gastroepiploic vein.3.Gastrocolic trunk was revealed in 67.2% of cases.The free_hanging portion seemed to have the capability of 'migration': it located in the subphrenic spaces in 20.7% of cases and distributed in the right lower quadrant predominantly in 17.2% of cases.The CT value of fatty density within greater omentum was(-104.97?10.78)Hu and no statistical significance was found in the difference between greater omentum and the subcutaneous tissue.Conclusion Gastroepiploic vessel is the landmark for the location of greater omentum.Axial,coronal and sagittal sections together with 3D reconstruction images could produce a full display of greater omentum and provide valuable data for the radiological diagnosis as well as surgery of reconstruction, pancreas and portal hypertension.

Objective:To study the effect of caprylic/capric acid glycerides (Lab), propylene glycol (PG) and Azone on the transdermal behavior of ketoconazole and miconazole nitrate in compound ketoconazole gel, to screen appropriate penetration enhanc-ers. Methods:Using a RYJ-6A-type transdermal drug diffusion tester, the effects of Lab, PG and Azone at different concentrations on the transdermal behavior of ketoconazole and miconazole nitrate in compound ketoconazole gel were studied. Results:3% PG showed the most obvious penetration enhancement, which could increase the permeation of ketoconazole by 2. 004 times, and increase the pen-etration of miconazole nitrate by 1. 795 times, and the differences were statistically significant (P<0. 05). Conclusion:The penetra-tion effect of 3% PG is obvious, which can be applied in compound ketoconazole gel.

Objective To determine the association of anomalies of female reproductive system with that of urinary system. Methods Two hundred and eighty-nine cases, including 59 with congenital vaginal inclined septum syndrome, 135 with septate uterus, 4 with unicornuate uterus, 13 with rudimentary horn of uterus, 58 with congenital absence of the uterus and vagina, 14 with imperforated hymen, and 6 with atresia of vagina, treated during the past 4 years, were analysed retrospectively. Results Anomalies of urinary system were more frequently found in patients with anisomerous anomalies of reproductive system(85. 53% , 65/76 cases). In 59 cases of congenital vaginal inclined septum syndrome, 43 had ipsilateral renal agenesis, 2 had one single pelvic kidney, 1 had bilateral horseshoe kidneys, 1 had left-side horseshoe kidney, 1 had one pair of renal pelvis and renal calices with ureters incorporated at middle and inferior segments on both sides. Ipsilateral renal agenesis was also seen in patients with rudimentary horn of uterus(14/14 cases) and unicornuate uterus(4/4 cases). However, there was no urinary system malformation seen in septate uterus patients (0/135 cases), imperforated hymen (0/16) and atresia of vagina (0/4 cases). Only 1 case of congenital absence of the uterus and vagina associated with ipsilateral renal agenesis. Conclusion Anomalies of reproductive ducts associated with renal malformations, especially anisomerous anomalies of reproductive system are not unusual. Early recognition and diagnosis is very important to prevention and treatment of such diseases.

Objective To investigate the relationship between plasma neuropeptide Y(NPY) and asphyxia in newborns. Methods Thirty-seven patients with neonatal asphyxia (asphyxia group) and 33 healthy pregnant women(control group )in their third trimester were chosen. The concentrations of plasma NPY were measured by radioimmunoassay. Results The levels of NPY in umbilical artery plasma was (187.47? 46.63) ng/L in asphyxia group,and (115.33?29.42) ng/L in control group. There were significant difference between them ( P 0.05). Conclusions The neonatal asphyxia was associated with NPY. NPY might play an important role in the pathophysiological changes in neonatal asphyxia.
