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 observe the cellular phenotype conversion of human mesenchymal stem cells (MSCs) cocultured indirectly with heat-shocked human sweat gland cells (SGCs) in vitro and explore the relative mechanism. Methods MSCs and SGCs were isolated and amplified in vitro. First,primary confluent cultures of SGCs were heat-shocked at 47℃. Then, the supernatants were collected immediately and 24 hours before applied to the third generation of MSCs. After seven days, the MSCs expressing CK7, CK18 and CEA were examined by two-step immunocytochemistry and flow cytometry and compared with the control group. Results MSCs treated with the supernatants of SGCs proliferated slowly, with no obvious morphological changes during seven days. Two-step immunocytochemistry demonstrated positive staining of CK7 and CEA in some cells. Additionally, the positive rate of CK7 and CEA was 5.76% and 2.01% by flow cytometry, much higher than that of the control sample, which was only 1.12% and 0.51% respectively (P ＜ 0.01 ). Conclusions There are some signal moleculars in the supernatants of heat-shocked SGCs, which benefits the transdifferentiation of MSCs.

Age-related white matter changes are considered as a manifestation of arteriolosclerotic small vessel disease and are associated with advanced age and vascular risk factors.White matter changes have been recognized as one of the manifestations of cerebral small vessel disease.They are the pathological basis of cognitive impairment and functional loss in the elderly.Studies have shown that when white matter changes develop to a certain extent,there will be many clinical symptoms,including cognitive impairment,dementia,depression,gait disturbances,and urinary incontinence,and they are associated with the increased risks of stroke and death.

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 observe the effect of static magnetic fields(SMF) on the proliferation of bone mesenchymal stem cells(MSC) in human. Methods: The MSC were obtained by using gradient centrifuge method, and then selected by the adhesive method. The third generation cells were irradiated by use of static magnetic fields at different intensities for 5 days(8 h/d). The method of MTT was employed to evaluate the level of proliferation. The parameters regarding the variation of the cell cycle were detected with the flow cytometry(FCM). Results: As compared to the control group, the proliferative rate of the MSC exposed to 0.05 mT SMF was significantly higher; there was no difference between the 0.10 mT group and control group; howere, cell proliferation was attenuated significantly when SMF intensity was 0.50 mT and 1.00 mT. No abnormal ploidy was found in any group. Conclusion: The effect of SMF on the proliferation of MSC is dependent on the magnetic intensity. 0.05 mT SMF can accerate the proliferation of MSC. 0.10 mT SMF have no effects on the growth of MSC. Wherease, 0.50 mT and 1.00 mT SMF can attenuate the growth of MSC.
