Objective To evaluate the value of three-dimensional power Doppler imaging(3D-PDI) in the discrimination between benign and malignant endometrium in women with postmenopausal bleeding. Methods Eighty-four women with post menopausal bleeding who examined by 3D-PDI were enrolled. All patients scheduled for pathological examination were divided into benign group (30 cases with endometrial polyps and 34 cases with hyperplasia) and malignant group (20 cases with endometrial carcinoma). Endometrial volume, vascularity index ( VI) , flow index ( FI) and vascularity flow index ( VFI) were measured. The diagnostic value of parameters derived from 3D-PDI was evaluated by using the receiver operating characteristic ( ROC) curve. Results Differences of these parameters (VI, FI and VFI) were considered statistically significant between two groups, the parameters of endometrial volume had no significant differences between two groups; the area under ROC curve(AUC) of the meaningful data were 0.976,0.888 and 0.894 respectively. Among these parameters, VI had the highest diagnostic value for discriminating between benign and malignant endometrium, the cut-off value of which was 2. 97 with a sensitivity of 95% and a specificity of 86%. Conclusions 3D-PDI is a good diagnostic tools in the discriminations between benign and malignant endometrium in women with postmenopausal bleeding.

Objective To study a improved technique by releasing the orbicularis retaining ligament in orbicularis oculi muscle supension blepharoplasty. Release of the orbicularis retaining ligament could cut off the contact between orbitomalar skin and periosteum at inferior orbital rim, and carry the point of tightening orbitomalar skin in orbicularis oculi muscle supension blepharoplasty. Methods There were 409 patients with apparent orbitmalar fold. The methods of releasing orbicularis retaining ligament and orbital septum fixation were added to improve the orbicularis oculi muscle supension blepharoplasty. Results 409 cases were treated using this method over the past 3 years. All results were satisfactory. No complications were observed. Conclusion This improved method of orbicularis oculi muscle supension blepharoplasty is useful for orbitomalar skin rolling, especially for orbitmalar fold. The release allows effective redraping and upward mobilization of the orbicularis of the lower lid and the premalar soft tissues. This method is a simple, safe and effective procedure for the correction of tear trough deformity and well-demarcated lid/cheek junction in lower eyelid belpharoplasty. It is one of the best choices for lower eyelid blepharoplasty.

To evaluate the application of intracavitary three-dimensional ultrasonography in the diagnosis of polycystic ovary syndrome ( PCOS). The three-dimensional volumes of ovary were measured by intracavitary ultrasonography in 40 PCOS patients and 40 normal controls. The diagnostic value of parameters derived from three-dimensional ultrasonography was evaluated by using the receiver operating characteristic (ROC) curve. The ovarian volume, stromal volume, and the stromal/total volume ratio in PCOS group were significantly higher than those in control group (both P ＜ 0. 05 ) ; the area under ROC curve ( AUC ) of them were 0. 876, 0. 926, 0. 886 respectively. Among these parameters, stromal volume had the highest diagnostic value for PCOS, the cut-off value of which was 7.52 cm3 with a sensitivity of 88% and a specificity of 90%. Volume parameters of ovary measured by intracavitary three-dimensional ultrasonography can offer quantitative information for the diagnosis of PCOS.

Objective To summarize the experience in treating coronary artery fistula (CAF) by using Guglielmi detachable coils. Methods During the period from July 2009 to November 2014 at the Affiliated Changhai Hospital of Second Military Medical University, interventional treatment of CAF by using Guglielmi detachable coils was performed in 40 patients. The clinical data were retrospectively analyzed. The feasibility, safety and effectiveness of this technique were evaluated. Results Successful transcatheter closure of CAF with Guglielmi detachable coils was achieved in all 40 patients; the average Guglielmi detachable coils used in each patient was(2.33±1.38) coils. No procedure-related complications occurred. Intra-operative angiography showed that residual shunt completely disappeared in 12 patients (30%) and blood flow was significantly decreased in 28 patients (70%). All the patients were followed up for 1-65 months, neither complications such as recurrent bleeding and ischemia nor stenosis and occlusion of related arteries, or fistula cavity rupture occurred. Conclusion The use of Guglielmi detachable coil in interventional treatment of CAF is safe and effective, although its long-term effect needs to be further verified.

But negative reation in 5 mites group from antigenic negative mice.

Objective To explore the value of strain rate and dobutamine stress echocardiography(DSE) in the diagnosis of coronary heart disease. Methods High-dose DSE was performed in 18 patients with coronary heart disease and 10 healthy persons, proved by selected coronary angiography. Ten patients had single coronary lesion, and the other 8 patients had more. By strain rate technology, systolic peak strain rate(SR_ SYS ) was measured in 12 segments of healthy persons and ischemic segments of patients. Results SR_ SYS of healthy subjects enhanced by the increasement of dose of DSE. In patients with single coronary lesion, SR_ SYS enhanced on the first states of baseline, 10 and 20 ?g?kg -1 ?min -1 ,while SR_ SYS changed non-significantly on 30 ?g?kg -1 ?min -1 , and began to decrease on 40 ?g?kg -1 ?min -1 . However in patients with more than one coronary lesions, SR_ SYS of 10 ?g?kg -1 ?min -1 became larger than that of baseline, while SR_ SYS didn't increase any longer on 20 ?g?kg -1 ?min -1 , and fell significantly on 40 ?g?kg -1 ?min -1 . Conclusions Combining stain rate and DSE to quantify local myocardial motion is valuable to offer many important clinic messages, and improves the diagnosis of coronary heart disease.

Acute lung injury/acute respiratory distress syndrome (ALI/ARDS) is a respiratory disorder with high morbidity and mortality caused by various causes. Exosomes can mediate cell communication through paracrine pathways, transfer proteins, lipids, nucleic acids, etc., and interfere with the biological functions of recipient cells. Various cell-derived exosomes have been reported to play an immunomodulatory role in the ALI/ARDS inflammatory model. This article reviews the mechanism of exosomes involved in immune regulation of ALI/ARDS and possible therapeutic approaches.

Objective To explore the clinical selection of surgical methods for pure stenosis at the end of the common bile duct.Methods The clinical data of 43 cases of pure stenosis at the end of the common bile duct treated in this hospital from October 2003 to June 2009 were retrospectively analyzed.Of the 43 cases, 12 underwent endoscopic sphincterotomy(EST), 9 sphincteroplasty of Oddi, 5 pancreaticoduodenectomy,8 Roux-en-y choledochojejunostomy and 5 choledocoduodenostomy,4 underwent drainage of the T tube after exploration of the biliary passage.Results Among 37 patients did not undergo the radical pancreaticoduodenectomy,6 had space-occupying lesions 5-19 months postoperatively.Five of them received pancreaticoduodenectomy again.Conclusion Pure stenosis at the end of the common bile duct should be carefully managed.

Objective:To study the relationship between the changes of hemoglobin concentration and serum ferritin concentration during pregnancy and the adverse pregnancy outcome, and to guide iron supplementation during pregnancy.Methods:122 parturient women who delivered in the Aerospace Center Hospital from August 2016 to may 2018 were prospectively selected. Data on hemoglobin concentration in each trimester and first day after delivery, ferritin concentration in first and second trimester, pregnancy outcomes of 122 parturient women was collected. Gestational diabetes mellitus, gestational hypertension (gestational hypertension and preeclampsia-eclampsia), preterm labor, premature rupture of membranes, postpartum hemorrhage, and neonatal weight were collected for statistical analysis.Results:⑴ There were significant differences in hemoglobin concentration among the early, middle, late pregnancy and the first day after delivery in 122 cases of parturient women ( P<0.01). There was significant difference in serum ferritin between early and middle pregnancy ( P<0.01). ⑵ There was a significant difference in hemoglobin between the gestational diabetes group and the non-gestational diabetes group ( P<0.05). Hemoglobin between pregnancy-induced hypertension (PIH) disease group and the normal hypertension group in early pregnancy have significant difference ( P<0.05), while hemoglobin between the preterm and term groups have significant difference ( P<0.05). ⑶ Patients with iron deficiency (ferritin ≥ 20 μg/L) were more likely to have premature rupture of membranes than those with iron deficiency, and those with anemia in late pregnancy were more likely to have premature delivery. ⑷ The risk factors of gestational diabetes mellitus were high body mass index (BMI) before pregnancy ( OR=3.578, 95% CI: 1.604-7.985) and high hemoglobin concentration during middle pregnancy ( OR=1.425, 95% CI: 1.058-1.918). High BMI before pregnancy ( OR=5.313, 95% CI: 1.746-16.169) and early high hemoglobin concentration ( OR=1.975, 95% CI: 1.048-3.720) were risk factors for PIH. The independent risk factor of PROM was serum ferritin ≥15 μg/L ( OR=2.836, 95% CI: 1.05-7.637). The independent risk factor of preterm birth was anemia in late pregnancy ( OR=13.625, 95% CI: 2.470-75.161). Conclusions:It is necessary to master the time and reasonable dose of iron supplement during pregnancy. Individualized iron supplement is the most appropriate method. Close monitoring should be carried out in the process of iron supplement to avoid adverse pregnancy outcomes.

OBJECTIVETo investigate the surgical techniques and therapeutic effect of eyelid divided nevus.

METHODSFrom January 2000 to January 2014, 27 cases with 27 eyelid divided nevi were treated by staged excision (2 cases), or full-thickness skin graft (20 cases) or frontal and facial expanded flaps (3 cases), or combined expanded flaps with skin grafts (2 cases) for large lesions. One case with skin graft underwent secondary treatment with expanded flap due to obvious scar.

RESULTSExcept for one case with residue lesion (0. 5 cm x 0. 5 cm), all the other cases underwent successful treatment with primary healing. All the patients were followed up for 3-48 months (average, 7. 4 months). Except for one case with secondary expanded flap treatment, all the other patients were satisfied with aesthetic and functional results. No occurrence happened.

CONCLUSIONSStaged excision and full-thickness skin grafts are simple and effective method for eyelid divided nevus. For large lesions, expanded flap, or combined with skin graft should be considered.
