Objective To observe the accuracy of abdominal ultrasound combined with transvaginal ultra-sound in the early diagnosis of ectopic pregnancy,thus to provide reference for clinical diagnosis of ectopic pregnancy. Methods The clinical data of 68 patients,who pathologically confirmed or conservative treatment with clinical diag-nosis of ectopic pregnancy,were retrospectively analyzed.All patients were treated with abdominal ultrasound,vaginal ultrasound examination.The accuracy and missed ectopic pregnancy rate of transvaginal ultrasound and abdominal B ultrasound and joint inspection were observed.And the presence or absence of abnormal ovarian uterus were recorded. Results By comparison with pathological diagnosis,joint diagnosis of 32 cases of ectopic pregnancy,the diagnosis rate was 94.1 %,missed 2cases,accounted for 5.9%;Transvaginal ultrasound diagnosis were 26 cases,accounted for 76.5%,missed by 8 cases,accounted for 23.5%;Abdominal ultrasound diagnosis were 24 cases,accounted for 70.6%,missed 1 0 cases,accounted for 29.4%.Joint inspection diagnosis rate was significantly higher than abdominal or vaginal ultrasound(χ2 =1 6.75,1 4.38,all P <0.05),and then compared transvaginal ultrasound and abdominal ultrasound diagnosis rate(P >0.05).Transvaginal ultrasound detected primitive heart tube pulse,mass,blood flow and gestational sac -like structures within the mass were significantly higher than the probability of abdominal ultra-sound(χ2 =26.71 ,7.1 8,1 0.25,50.28,25.69,6.39,all P <0.05).Conclusion United abdominal ultrasound and transvaginal ultrasound can significantly improve the early detection rate of ectopic pregnancy,which can provide refer-ence for clinical diagnosis and treatment.

To explore the clinical value of the color Doppler flow imaging (CDFI))in diagnosis of vascular disease in the lower extremities of patients with type 2 diabetic mellitus(2DM), 102 patients with 2DM and 20 normal controls were included in this study. The values of vessel intimal-media thickness(IMT), the size of plaque, vessel diameter, percentage of diameter stenosis, percentage of the peak systolic velocity acceleration at stenosis orifice, and velocity wave pattern were obtained with CDFI. The study indicated that the incidence of vasculer disease in the lower extremities as shown by CDFI was higher than that as assessed by clinical manifestations only. By CDFI,the severity of the stenosis or the obstructive lesions of blood wessels in lower extremities was better evaluated,moreover quantitative indexes for clinical diagnosis were provided.

Objective To optimize the preparation of high-efficiency galactocylated poly-L-lysine (Gal-PLL) ligand of the asialoglycoprotein receptor in liver, providing premise and foundation for upper preparation of ultrasound contrast agent of liver targeted nanoscale perfluorocarbon microballoon and the liver targeted molecular imaging. Methods Chemical reactions of reductive amination were carried out on group A and group B according to different proportions of reaction component. Each group was subdivided into three subgroups. In group A, three different molar ratios of D-galactose and poly-L-lysine (PLL) were compounded respectively with equivalent and sufficient reductant borohydride. In group B, identical molar ratios of D-galactose and PLL were compounded respectively with three unequal reductants borohydride. Products of each group were separated and purified by sephadex column to acquire different molecular weight distributions and the results were analyzed. Results In the condition of identical reductant, the peak curve of compound's molecular weight appeared earlier when D-galactose decreased properly. In the condition of identical molar ratio of D-galactose and PLL,the peak curve of compound's molecular weight appeared also earlier when reductant decreased properly. When the molar ratio of D-galactose and reductant was 1∶1, the peak curve of compound Gal-PLL and free components was more obvious, and the quantity of compound Gal-PLL increased to maximum. Conclusions In the condition of identical reductant, coupling effect of D-galactose and PLL increased when D-galactose decreased properly. In the condition of identical molar ratio of D-galactose and PLL, coupling effect was better when reductant decreased properly. When the molar ratio of D-galactose and reductant was 1∶1, coupling effect of them was the best. The coupling of D-galactose and PLL was related to not only the proportion of D-galactose and PLL, but also the proportion of D-galactose and reductant.

Lumbar intervertebral disc herniation clinical symptoms and signs are very complicated, lumbocrural pain is the most characteristic clinical symptoms,and show the site (range or area), intensity, nature, evolution, influence factors and adjoint symptoms and so on has certain characteristics and rules. Among them, the dermatomal pain, kinesthetic dysesthesia, dynamic changing pain and lesions segment vertebral side deep tenderness are the most impotent characteristics and rules of pain, therefore, can be regarded as the main basis of clinical diagnosis of the disease, and also the core content of this article.

Pain is all lumbocrural pain cases very common clinical symptoms,but the etiology, pathology, site (range or area), intensity, nature, evolution situation and influence factors of pain usually has some certain characteristics and rules, these differences particularly are regarded as the primary and important basis or clue for the clinical diagnosis and differential diagnosis of related diseases. In addition, according to these differences can determine the individual diagnosis of lumbar intervertebral disc herniation as well, including typical and atypical, simple and compound, the general and special cases, these be- come the basis to determine the individualized therapeutic schedule of this disese.

Pain is common clinical symptoms of lumbocrural, but the etiology, pathology, sites (range or area), intensity, nature, evolution situation and influence factors of pain has some certain characteristics and rules. These differences particularly were regarded as the primary and important basis or clues for the clinical diagnosis and differential diagnosis of related diseases. A series of exclusive diagnosis for similar symptoms is premise of diagnosis of lumbar intervertebral disc protrusion. Ideas and methods of differential diagnosis of lumbar intervertebral disc herniation can help the diagnosis and identification.

Objective To detect the serum prohibitin protein(PHB)level in children with renal interstitial damage and analyze the correlation between PHB and renal interstitial fibrosis(RIF). Methods Serum PHB protein levels were determined by Western blot analysis in 36 children with kidney diseases,and 30 healthy children were studied as control. Levels of BUN,Scr,and urinary microprotein series(including ALBU/Cr,NAGU/Cr,IgG U/Cr,α1-MU/Cr)were studied by automatic biochemical analyzer. Renal interstitial damage was semiquantitatively graded according to Katafuchi's method. The correlation between serum levels of serum PHB protein and those of BUN,Scr as well as urine microprotein were analyzed. Results Serum PHB protein was positive in children with diverse kidney diseases however it was negative in the normal controls(P ＜ 0.05). Serum PHB levels were significantly higher in children with proliferative glomerulonephritis than those with non-proliferative glomerulonephritis(P ＜ 0.05). Statistical analysis indicated that serum PHB levels positively correlated with the degree of tubulointerstitial lesions(r ＝ 0.868,P ＜ 0.001)as well as the glomerular injuries(r ＝ 0.753,P ＜ 0.001). And,serum PHB levels were also positively correlated with urinary microprotein including NAG(r ＝ 0.586,P ＜ 0.001)and IgG(r ＝ 0.341,P ＜ 0.001). Conclusions Serum PHB levels were significantly increased in children with kidney diseases and were positively correlated with the degrees of renal interstitial damage,suggesting that PHB might be a potential clinical marker for detecting tubulointerstitial lesions.
