Objective　To establish the normal growth velocity of fetal liver length and compare them with those of intrauterine growth retardation, pregnant diabetes and maternal-fetal blood types imcopatible. Method　Three hundred and five normal pregnant women and 24, 10, 16 pathological pregnant women of intrauterine growth retardation (IUGR), gestational diabetes and maternal-fetal blood types incompatible respectively had ultrasonographic measurement of fetal liver length at 18 to 42 weeks′ gestation. Results　Normal fetal liver length has a linear relation to gestational age, and showed a significantly rapid increase after 28th week with a growth rate of 1.76 mm per week, and 1.00 mm per week before 28th week (P<0.05). The growth rate of IUGR group before and after therapy were 1.19 mm and 1.23 mm per week, significantly lower than those of normal group (P<0.05). The growth rate of pregnant diabetes group before and after therapy were 1.63 mm and 1.63 mm per week, no statistical significance with normal group (P>0.05). The growth rate of maternal-fetal blood types incompatible group before therapy was 1.98 mm, showed no difference with normal group (P>0.05), but after therapy, the growth rate of fetal liver was 1.38 mm per week, significantly lower than normal group (P<0.05). Conclusion　Dynamic measurement of fetal liver length can help us to understand whether the fetus grow well in uterus and whether the treatments are effective.

Treatment and the clinical outcome of patients with head and neck cancer are determined by accurate staging and assessment of the cervical lymph nodes for metastases is an important step of this process. Ultrasonography, ultrasonography-guided fine needle aspiration (FNA), CT, MRI and PET/CT are used in the assessment of cervical lymph nodes. Ultrasonography guided FNA is advantageous in ease of application, minimumal invasiveness to patients, and less contraindications. Combined with cell block and molecular biology, FNA can be an effective tool for the diagnosis. The present article reviewed the diagnostic value of ultrasonography guided FNA in cervical lymph node assessment in patients with head and neck cancer.

Objective To evaluate the value of color Doppler flow imaging(CDFI) in the diagonosis of placental site trophoblastic tumor(PSTT). Methods After being examined by transvaginal CDFI, four of six patients underwent curettage and two of them had hysterectomy and attached by chemical treatment. All the patients were verified to have a PSTT by pathology. Results The image of PSTT in CDFI included different size at different site, low resistence index (RI) of vessel around the lesion, and absence of vessel in the lesion. Conclusions The characteristic image in CDFI is helpful to the diagnosis of PSTT.

Objective To open the reset common bone and open ordinary osteosynthesis(MIPPO)(in effect in the treatment of high energy tibial fracture.Methods High energy tibial fracture in 42 cases of patients,according to the condition of the patient and the treatment were divided into two groups,using open reduction and bone treatment (open group,22 cases),treated with MIPPO technique(MIPPO group,20 cases).The indicators of operation,postop-erative complications and clinical efficacy of the two groups were observed.Results The operation time,intraopera-tive bleeding volume,fracture healing time of the MIPPO group were (75.2 ±9.7)min,(107.3 ±11.3)mL,(13.1 ± 3)weeks,which of the open group were (73.4 ±10)min,(208.5 ±16.3)mL,(18.2 ±4.7)weeks,the two groups had no statistically significant differences in operative time(P >0.05),two groups of blood loss,fracture healing time, the differences were statistically significant(t =23.153,4.143,all P <0.05);the complication rate in the MIPPO group was 10.0%,tibial shaft fracture healing function excellent rate was 95.0%.The complication rate of the open groupwas healing function excellent rate was 72.7%,36.4% tibial shaft fracture,there were significant differences between the two groups(χ2 =12.316,22.964,all P <0.01).Conclusion MIPPO technology in the treatment of high energy tibial shaft fractures,with less bleeding,fracture healing fast,and the characteristics of a significant effect, which is worth promoting.

Objective To investigate the value of transvaginal ultrasound in the diagnosis of endometrial polyps. Methods One hundred and ten patients diagnosed as endometrial polyps by transvaginal ultrasound and undergone operative hysteroscopy and histologic examination, were analyzed retrospectively.Results Among 110 cases 75 cases (68.2%) were accurately diagnosed by transvaginal ultrasound,while 35 cases (31.8%) were misdiagnosed.The diseases misdiagnosed included endometrium hyperplasia,intrauterine adhesions and submucousmyoma.Conclusions Combining clinical symptoms with ultrasonogram characters and optimal time of detection can reduce the misdiagnostic rate of endometrial polyps.

ObjectiveTo evaluate the probability of the fetal heart scanning in first trimester(11 -14+6 week) by transabdominal ultrasonography.MethodsBy using advanced ultrasound machine with high resolution transabdominal probe,249 fetal hearts were scanned.Four chamber view,left and right outflow view,three vessels view were obtained.The successful observation rates of these views under different gestational age were recorded.For 18 pregnant women with suboptimal transabdominal scanning condition,transvaginal scan were supplemented.ResultsAmong 249 singleton fetuses with low risk of congenital heart disease,four chamber view was successfully visualized in 227 (91.2％),left outflow view in 125(50.2％),right outflow view in 102(40.9％),three vessels view in 98(39.4％).The successful observation rate of these four views increased with gestational ages.The successful observation rate of each view in successive gestational age showed remarkable difference (P ＜ 0.05).The four chamber view had the highest successful observation rate with 95％ after 12 weeks.After 13 weeks,left and right outflow views visualizing rate was above 85％.Transvaginal scanning can increase the four chamber view successful observation rate.For observation of other views,transvaginal scanning,however,showed no superior than transabdomial scanning.ConclusionsHigh resolution transabdominal probe can be used to perform the fetal hearts scanning in early trimester.It will benefit to find the fetal heart malformation.

Objective To investigate the relationship between cysteinyl leukotriene and clinical response to antileukotriene treatment,and to help select a clinical pharmacologic scheme.Methods Seventy-eight cases with acute mild-moderate asthma were treated with montelukast in a four-week trial.Asthmatic symptom score,usage of ?_2 receptor agonist,percentage of eosinophil,serumal IgE concentration,spirometry and urinary leukotriene E_4(uLTE_4)were measured pre- and post-treatment.Logistic analysis was used to access the various clinical parameters correlated with the response to montelukast.Results There were 48 responders and 30 nonresponders.The uLTE_4 level from the responders was higher than that of nonresponders(P0.05).Subjects with a uLTE_4 level of ≥1 200 pg/mL were11.5 times more likely to respond to montelukast than those with

Objective To investigate ultrasonography imaging feature of intravenous leiomyomatosis (IVL).Methods Analysing 34 cases of IVL retrospectively,which had been treated and diagnosed in the hospital from Jan,1998 to Dec,2003.Results Among 34 cases,2 cases were diagnosed as IVL,20 cases were diagnosed as uterine leiomyoma or uterine leiomyoma with degeneration and 12 cases as uterine leiomyoma with adenomyosis.Conclusions Knowledge shortage on the clinical feature of IVL causes the low rate of accurate diagnosis of IVL by ultrasonography imaging.

Objective To evaluate the value of endometrial volume measurement and 3-dimensional power Doppler imaging(3D-PDI) in the differentiation between endometrial polyps and endometrial hyperplasia.Methods One hundred and fifty-six women who diagnosed as thick and inhomogeneous endometrium or hyperechogenic focal intrauterine structures by 2D ultrasound were enrolled,including 50 patients with endometrial polyps in the proliferative phase,51 cases with hyperplasia and 55 cases with normal histology or others.All were scheduled for hysteroscopy,dilatation and curettage,and the ultrasound was performed within 24 hours before the procedure. Endometrial volume, vascularity index (VI), flow index (FI) and vascularity flow index (VFI) were measured. These parameters were compared between endometrial polyps group and endometrial hyperplasia group.Results These parameters (endometrial volume,VI,FI and VFI) were all considered statistically significant between two groups.Conclusions Endometrial volume and 3D-PDI are good diagnostic tools in the differentiation between endometrial polyps and endometrial hyperplasia.

Objective To investigate the value of transvaginal contrast-enhanced ultrasonography (CEUS)in the diagnosis of adnexal masses.Methods Thirty patients with adnexal mass were examined by conventional 2D imaging and contrast tuned imaging(CnTI)technology.The results were compared with pathological results and the CEUS features wet concluded.Results There were 21 cases of benign adnexal masses and 9 cases of ovarian malignancies among 30 patients.The CnTI technology can distinguish between solid and cystic parts in masses.CEUS showed that malignant tumor had the high microvessel density and these vessels were irregular in shape.Partial malignant masses had the characteristic in-out phases in CnTI imagine.Conclusions Transvaginal CEUS is benefit to improve the accuracy of diagnosis of pelvic adnexal masses.
