Objective To summarize the sonographic features and the diagnostic value of transvaginal three dimensional OmniView sonography for congenital uterine malformation. Methods Thirty-six patients who were suspected as uterus septus on transvaginal two-dimensionalultrasound (2D US) were examined by transvaginal three dimensional ultrasound (3D US) of OmniView. The coronal plane images were acquired. The fundus,cavity and cervix of the uterus were analyzed. The depths of fundal cleft were measured.In comparison with the test results of hysterosalpingography (HSG), hysteroscopy, hysteroscopy combined with laparoscope or magnetic resonance imaging (MRI), the sonographic features and the diagnostic value of transvaginal three dimensional OmniView sonography were summarized. Results Among the 36 cases underwent transvaginal three-dimensional ultrasound (3D US), 16 cases were diagnosed as incomplete septate uterus, 5 cases as complete septate uterus, 5 cases as arcuate uterus, 4 cases as bicornuate uterus, 4 cases as gemini and 2 cases as unicornuate uterus. The results of all 36 cases were confirmed by surgery or magnetic resonance imaging (MRI). The sonographic features of transvaginal three dimensional OmniView sonography:(1) Twenty-one septate uterus had convexes (in 12 cases) or minimally depressed fundus (in 9 cases, depth of cleft ≤ 1.0 cm) and had Y-shaped (16 incomplete septate uterus without septum extending into cervix) or V-shaped cavity (5 complete septate uterus with septum extending into cervix). (2) Five arcuate uterus had an obtuse angle at the central point of septum. (3) Four bicornuate uterus had fundal depression more than 1.0 cm and were divided into two cornuas. (4) Four gemini had two complete uterus and cervix. (5) Two uterus unicornis had single endometrial and smaller than normal. Conclusions Transvaginal 3D OmniView sonopgraphy of uterine may display a good coronal plane, on which the relationship of the cavity and the fundus, the depth of fundal cleft and the angle at the central point of the septum can be well depicted and measured. It is a practical, reliable and noninvasive method, and superior to 2D US in the diagnostic classification of complex uterus malformation.

Objective To evaluate the clinical effect and safety of umbilical cord ligation in the fetocide of complicated monochorionic multiple gestations.Methods From January 2009 to December 2012,clinical data of 18 women with complicated monochorionic multiple gestations who experienced intrauterine percutaneous umbilical cord ligation in Peking University Third Hospital were collected.Among the patients,6 were selective intrauterine growth restriction (1 with type Ⅰ,4 with type Ⅱ,1 with type Ⅲ) ; 4 were acrania or hydropic twins; 4 were aeardiac twins,2 were complicated triplet gestation; 1 was twin-twin transfusion syndrome with right ventricular dysplasia and 1 was monochorionic diamniotic (MCDA) with caesarean section history.The procedure was performed under both endoscopic and sonographic guidance.The gestational age at the time of the procedure were 17-27 +6 weeks.The procedure and perinatal outcome were analyzed.Results (1) The procedure was performed successfully in all the 18 cases.The average duration of the procedure was 63 min (24-156 min).The blood loss was 7.6 ml (5-20 ml).The mean gestational age at the time of the procedure was 20 weeks (17-27 +6 weeks).The average birth weight of the neonates was 2441 g(1000-3400 g).(2) There were 20 fetuses survived.Two fetuses had cardiac anomalies and were terminated in the following 2-3 weeks.Intrauterus fetal demise occured in 3 twin reverse arterial perfusion syndrome (TRAP) cases 3-14 weeks after the procedure.1 case delivered as early preterm birth at 28 weeks and the neonate died of respiratory distress syndrome (RDS) and hypoxie-ischemicencephalopathy (HIE).Fourteen neonates were in healthy and normal development by 3-51 months' followup.(3) Fourteen cases delivered at more than 28 weeks (28-38 weeks,averagely 33 + 1 weeks).The gestational weeks were prolonged by 5-21 weeks (averagely 13 +4 weeks).Among them,3 case were early preterm birth (28-33 weeks) and 3 were late preterm birth (34-36 weeks).Conclusion Percutaneous umbilical cord ligation is a reliable technique for the fetocide of complicated monochrionic mutilple gestations,especially for monochronic monoamniotie pregnancies.

Objective To investigate the specific measures and effect of the nursing care for elderly lung cancer patients who were receiving the treatment of CT-guided permanent interstitial co-implantation of 125I seeds and slow-released fluorouracil.Methods Active care,including adequate preoperative preparation,proper support during operation and postoperative nursing,was carried out for fifty-three elderly patients with lung cancer during their treatment course of CT-guided permanent interstitial brachytherapy with co-implantation of 125I seeds and slow-released fluorouracil.Results In order to ensure accurate puncture and the smooth particle implantation,the possible conditions which might happen after the procedure were informed to the patients before the surgery and useful advice was given to patients to guide their daily activities.All 53 patients showed no obvious fear before surgery and made good cooperation during the procedure,moreover,they well responded to the therapy and recovered pretty soon.Conclusion CT-guided permanent interstitial co-implantation of 125I seeds and slow-released fluorouracil is a safe,minimally-invasive and newly-developed technique with reliable effect,which is especially suitable for aged patients.Active and adequate nursing care is essential during the whole therapeutic course.

Objective To investigate the changes of saliva biochemical parameters in the dynamic evolution of “normal constitution - kidney deficiency constitution - kidney deficiency syndrome”.Methods Totally 24 male and female SD rats of 3 months old (12 male rats and 12 female rats) were put in packet pair cage. Pregnant rats were randomly divided intoⅠ andⅡ groups, 6 rats in each group.Ⅰ group was without intimidation during pregnancy, with normal feeding, and then after the birth, 20 rats were randomly selected as normal control group and kidney deficiency syndrome model group, 10 rats in each group, half male and half female.Ⅱ group, from gestation day 2, was given intimidation until postnatal. 10 half male and half female rats were randomly selected as model group of kidney deficiency constitution. Rats in each group received normal feeding conditions for 6 weeks. The kidney deficiency syndrome model group was given intramuscular injection of hydrocortisone 25 mg/kg body weight every day, while normal control group and kidney deficiency constitution model group were injected with the same amount of normal saline for 10 consecutive days. The changes of salivary biochemical parameters were observed in each group of rats.Results Compared with the normal control group, salivary pH in the kidney deficiency constitution group and kidney deficiency syndrome group significantly increased (P<0.01). CK, ALT, AST, ALP levels in the kidney deficiency constitution group were reduced, but the contents of K, P, TP, AMY increased. The levels of CK, ALT, AST, ALP and LDH in the kidney deficiency syndrome decreased, while the contents of K, P, TP, and AMY increased (P<0.05,P<0.01). Compared with the kidney deficiency constitution group, the content of LDH in the kidney deficiency syndrome group decreased (P<0.05).Conclusion Rat saliva composition changes did occur in the kidney deficiency constitution group and kidney deficiency syndrome group.

Objective To investigate the effects of xuanzhi analgesic tablets on plasma levels of 6-keto-prostaglandin Flα(6-K-PGFlα) and thromboxane B2(TXB2) in rats with acute blood stasis. Methods Sixty SD rats were divided into six groups randomly, namely normal control, model control, positive control, xuanzhi analgesic tablets at 1. 36, 2. 72, and 5. 44 g·kg-1 groups. The rat model of blood stasis syndrome was caused by subcutaneous injection of adrenaline incorporated with ice-bathing. The effects of xuanzhi analgesic tablet on 6-K-PGFlαand TXB2 were observed. Results Compared with the normal control,plasma level of 6-K-PGFlα was significantly reduced(P<0. 01) and that of TXB2 in the model control was evidently increased(P<0. 01). Three dosages of xuanzhi analgesic tablets significantly raised 6-K-PGFlαlevel(P<0. 05)and lowered TXB2 level (P<0. 05). Conclusion Xuanzhi analgesic tablets significantly adjust plasma levels of 6-K-PGFlαand TXB2in rats with acute blood stasis. Xuanzhi analgesic tablets can coreect the imbalance between PGI2 and TXA2 through increasing 6-K-PGFlαand desearing TXB2 levels.

Objective: To assess the regional systolic and diastolic function of left ventricle by pulsed wave Doppler tissue imaging ( PW-DTI) in patients with coronary artery disease ( CAD ) . Methods : Seventy-seven cases of coronary angiography were adopted for study and grouped in terms of severity of coronary arterial lesion. Peak systolic, peak early diastolic, and peak late diastolic motion velocities (Sm, Em and Am, respectively) were recorded at 6 different sites on the basal and medial segments corresponding to the anteroseptal, posteroseptal, lateral, anterior, inferior, and posterior walls of the left ventricle with PW-DTI. Results: Am in segments corresponding to normal coronary arteries (group A) was lower than in segments corresponding to slightly stenosed coronaries (group B). There was no significant difference in Sm and Em between group A and group B. Compared with group A, Sm, Em and Am were significantly decreased in segments corresponding to severely stenosed coronary arteries ( group D). Conclusion : PW-DTI could be used to evaluate quantitatively and accurately the regional mvocardial function of left ventricle in patients with CAD.

Objective To study the diagnostic value of imageology for pyelic carcinoma.Methods The accuracy of qualitative diagnosis and sensitivity were analyzed by comparing various imaging examinations in 19 patients with pathologically proved pyelic carcinomas.Results Irregular filling defect and hydronephrosis were seen in the renal pelvis and calyces on intravenous pyelography(IVP).On CT scan,when the tumor was small,soft tissue mass was in the renal pelvis and the calyces.When the renal parenchyma involved by tumors,the soft tissue masses with unhomogeneous density,liquefaction necrosis in the renal pelvis and the parenchyma were seen.On contrast-enhanced CT scan,enhancement from slight to moderate was found in the lesion.The lesions were detected by IVP in 9/12 cases,by BUS in 10/16 cases,by CT in 18/19 cases and by MRI in 3/3 cases.Conclusion IVP and CT are the first method of choice to diagnose the pyelic carcinoma,BUS can be used as a screening method.While in evaluating the tumor involving the parenchyma of the ren or distant metastasis,CT and MRI are superior to IVP.

This study was designed to determine the impact of chrysoeriol on proliferation and cell cycle progression in the human multiple myeloma cell lines RPMI 8226 and KM3, and its related molecular mechanisms. Chryseoriol was identified by using the phosphorylated AKT-specific cytoblot high throughput assay. CCK-8 assay was employed to examine the growth inhibition rate and IC(50) (48 h) in peripheral blood mononuclear cells (PBMNCs), RPMI 8226 and KM3 cells treated with chrysoeriol at various concentrations. Cells were labeled with 5-6-carboxyfluorescein diacetate succinimidyl ester (CFSE), and the proliferation dynamics was detected by flow cytometry and analyzed with ModFit software. The cell cycles of RPMI 8226 and KM3 cells were measured by flow cytometry when the IC(50) concentration of chrysoeriol was adopted. The alterations in cell-cycle related proteins (Cyclin B1, Cyclin D1, p21) and proteins in PI3K-AKT-mTOR pathway were determined by Western blot analysis. The results showed the proliferation of multiple myeloma cells was significantly inhibited by chrysoeriol, resulting in cell cycle arrest in G(2)/M phase. Chrysoeriol could significantly reduce the expression of p-AKT (s473) and p-4eBP1 (t37/46) protein, meanwhile enhanced Cyclin B1 and p21 protein expression. Similar effects were not observed in PBMNCs from normal donors. It was concluded that chrysoeriol was a selective PI3K-AKT-mTOR pathway inhibitor. It restrained the proliferation of human multiple myeloma cells, but didn't affect proliferation of PBMNCs from normal donors. It might exhibit the cell cycle regulatory effect via the inhibition of PI3K-AKT-mTOR signal pathway.
