Objective To explore the application of ultrasonography combined with hysteroscopy for the diagnosis of dated uterine false passage. Methods From May 2012 to May 2013, a total of 3437 cases were examined in the center by ultrasonic monitoring combined with hysteroscopic examinations.Dated uterine false passage was found in 4 cases.Under the guidance of ultrasonography, the hysteroscope was introduced into the uterine cavity.The ultrasonic probe was put at the site above the pubic symphysis for comprehensive examinations, with uterine distention fluid as reference. Results There were 2 cases of uterine anteversion and 2 cases of retroversion.There were 1 case of intracervical mouth stenosis, 1 case of intracervical mouth adhesion, and no intracervical mouth stricture or adhesion in 2 cases.The uterine false passage was located in the anterior wall in 2 cases and located in the back wall in 2 cases.The distance to serosal surface was about 3 mm at the thinnest place.The uterine false passage was 3-4 cm in depth. Conclusion Ultrasound monitoring combined with hysteroscopic examination can determine the part of the uterine endometrium line, improve the accuracy of diagnosis and treatment of intrauterine lesions.

Several reconstruction techniques are available after gastrectomy. Roux-en-Y reconstruction following distal gastrectomy is the reference in terms of long-term functional and endoscopic outcomes. It is the preferred reconstruction for benign lesions and early gastric cancer. In patients with advanced gastric cancer, BillrothII (reconstruction is an acceptable alternative. After total gastrectomy, Roux-en-Y reconstruction is the simplest solution, with satisfactory functional outcome. Addition of a jejunal reservoir seems to improve long-term outcome after total gastrectomy and could be of benefit to patients with good prognosis. After distal or total gastrectomy, hand-sewn anastomoses should be preferred because of lower costs. Mechanical sutures can facilitate transhiatal esophagojejunostomy. After proximal gastrectomy, esophago-gastric anastomosis is the basic reconstruction method. Gastric remnant is made into gastric tube in the operation. The effect of pyloroplasty remains controversial, and further study is needed to improve the quality of life after operation.

OBJECTIVE To study the constituent ratio of the pathogenic fungi of blood culture in recent 24 months and their resistance in our hospital.METHODS Blood culture of patients in our hospital was performed by BacT/AlerT120 and the isolated pathogenic fungi were identified by API identified tests(API Inc,France).In(addition) antibiotics sensitivity test was by K-B.RESULTS Of the specimens in 4135 cases,there were 110 strains((2.7%)) with Candida albicans(29%).C.tropicalis(21%) and C.portugal(9%).The(specimens) come from(hepatobilliary)(25%),neurosurgery(24%) and emergency(10%) departments.CONCLUSIONS It is important and necessary to monitor the circumstance of fungal(infection) and resistance of the pathogenic fungi due to its(morbidity) increased.

Objective: To determine the changes of upper airway morphology induced by mandible position from central relation to advancement position in patients with obstructive sleep apnea syndrome. Methods: Nineteen patients (17 males and 2 females) suffering from obstructive sleep apnea syndrome were confirmed with polysomnography. Occlusal wax record was made with mandible in advancement position. Helical computed tomography was performed on each patient in central relation and mandibular advancement position with wax record in situ respectively. On each slice, anteroposterior and transverse diameters were obtained. Airway shape was expressed as the anteroposterior/transverse (AP/T) diameter ratio. Paired samples t test was employed to compare the measurements. Results: With mandibular advancement, average and minimal diameters of glossopharynx and hypopharynx were increased significantly. Compared with it, the change of transverse diameter was more prominent. All segments of upper airway were increased significantly except hypophaynx laterally. Moreover, the change of velopharynx shape was observed on axial planes. Ellipse with transversal long axis became more compressed. Conclusion: Upper airway morphology of all segments was influenced by mandibular advancement whether in the sagittal or transverse plane of space, or airway shape. Not only anatomic connection but also regulation of the nerve system and other still unknown mechanism make contribution to the changes of upper airway morphology in patients with obstructive sleep apnea syndrome. The changes of upper airway morphology above mentioned constitute the rationale of treatment of obstructive sleep apnea syndrome with oral appliances.

Objective To construct a EGFP-labled recombinant plasmid of VEGF165 (vascular endothelial growth factor) gene, and to study the transfection and expression of VEGF165 eukaryotic expression plasmid in mesenchymal stem cells (MSCs). Methods pIRES2-EGFP-VEGF165 recombinant plasmid was constructed, which was then transfected into rat MSCs. ELISA and MTT were used to detect the expression level and biological activity of VEGF in the conditioned medium after transfection. Results There was a significant increase in VEGF protein in the MSCs after being transfected with pIRES2-EGFP-VEGF165. The conditioned medium after transfection showed the biological activity of stimulating the proliferation of endothelial cells. Conclusions The pIRES2-EGFP-VEGF165, a eukaryotic expression plasmid for VEGF165 gene, is constructed. High levels of VEGF protein expression can be obtained in the MSCs transfected with pIRES2-EGFP-VEGF165. The expressed protein has the biological activity of VEGF.

Objective To study the clinical features and pathology of renal damage in patients with MPA. Method The clinical pathological changes of 23 MPA patients were analyzed and the patients with positive ANCA were compared with those with negative ANCA. Results Most MPA patients were senile and male with the symptoms of lung damage, pleuritis, arthritis and myalgia as well as extrarenal symptoms such as fever, weight-loss, and anorexia. 65.2% of the patients were ANCA (+). Symptoms of renal function damage were hematuria and proteinuria, which could be found in all the patients. Different degree of renal damage could be detected. Glomerular cresent formation, which were mostly fibrous, could be found in all of the 23 patients. Half of the patients have tuft necrosis and interstitial vessel vasculitis. Conclusion MPA patients often have extrarenal symptoms besides renal function damage. Patients with positive ANCA differs from patients with negative ANCA in both clinical manifestation and kidney pathology.
