Objective To summarize the sonographic features of fetal limb deformity. Methods Systematic continuous sequence approach (SCSA) was performed with two-dimensional and three-dimensional ultrasonography(USG) in 28 383 fetuses to observe the fetal limb development, posture abnormality and other accompanied malformations. Compared with the pathological and radiological findings, the characteristics of fetal limb deformity on USG were summarized. Results Among 28 383 fetuses prenatal ultrasound detected 207 cases of fetal malformations (0.7%, 207/28 383) including 29 cases of limb deformities (14%, 29/207). In the 29 cases, there were osteogenesis imperfecta in 2 cases, syndactyly in 1 case, cleft hand deformities in 1 case, uncifom hand in 1 case, clubfoot deformity in 12 cases, cleft foot in 1 case, micromelia in 4 cases, limb body wall complex in 1 case, forearm defect in 2 cases, and radius absence in 4 cases. Chromosome karyotype analysis was conducted in 7/29 cases, of which 6 cases were normal and 1 case was trisomy-13 with syndactyly. In addition, the fetal limb deformities were found at 17-19 weeks of gestation in 4 cases, at 20-24 weeks in 23 cases, and at 25-33 weeks in 2 cases. In summary, 27/29 cases were identiifed at 17-24 weeks of gestation. Conclusions Prenatal ultrasound is the ifrst-choice method for screening of fetal limb deformity. The detection rate of limb deformity could be greatly improved by using SCSA method with the supplement of 3D ultrasound.

Objective To investigate the effect of Tongqiao Yinao decoction ( TYD) on postoperative cogni-tive dysfunction in elderly patients and its underlying mechanisms .Methods 100 anesthetic patients for orthopedic surgery were randomly divided into the TYD-treated group and control group ,50 patients in each group .In TYD-trea-ted group,patients received 150mL TYD orally,twice daily for constitutive 15 days,beginning from the day of admis-sion in addition to conventional symptomatic and supportive treatment .While patients in control group received no TYD.Mini-mental state examination ( MMSE) was used to evaluate the patients′cognitive function before and after anesthesia.Meanwhile,blood samples of patients were also collected to test the expression levels of IL -6.Results There was no significant difference between the two groups before operation .However ,TYD-treated patients had signif-icantly lower incidence rate of POCD than the controls ( 20% in the control group , and 12% in the TYD-treated group;χ2 =4.332,P=0.037) 7 days after operation.The incidence rates of POCD in the TYD-treated group and control group were 30%and 38%1 day after operation ( P>0.05),28% and 20% 3 days after operation ( P>0.05),respectively.Compared with that before operation ,the blood levels of IL-6 in the two groups significantly increased 3 days after operation (control group,t=2.412,P=0.009;TYD-treated group,t=1.429,P=0.039).In contrast to the control group,the level of IL-6 in TYD-treated group declined to the baseline (the control group,t=0.851,P=0.049;TYD-treated group,P=0.404).Interestingly,compared with the controls,the TYD-treated patients had a significant lower level of IL-6 after operation (t=1.198,P=0.035).Furthermore,Pearson correlation analysis showed that change of IL-6 level in blood was negatively correlated with MMSE score (r=-0.782,P=0.022). Conclusion TYD can improve postoperative cognitive dysfunction in elderly patients ,presumably through decreasing the level of IL-6 in blood.
