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.

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.

BACKGROUND:Recent development of bioengineering technology and tissue-engineered nerve brings a new hope for the treatment of peripheral nerve injuries, which has gradual y become a research spot. OBJECTIVE:To review the new progress in the repair of peripheral nerve injuries using seed cells, biomaterials and tissue-engineered nerve construction technology. METHODS:PubMed and CNKI were searched by the first authors for articles concerning nerve tissue engineering and repair of peripheral nerve injuries published prior to July 2013. The keywords were“tissue engineering, peripheral nerves, nerve injuries, stem cells, Schwann cells, scaffold, growth factor”in English and Chinese, respectively. The articles published recently or in the authorized journals were preferred in the same field. Final y, 63 articles were included in result analysis. RESULTS AND CONCLUSION:Up to now, there is a great advance in the tissue engineering technology for the repair of peripheral nerve injuries. However, most studies are stil in experimental step. For the clinical application of nerve tissue engineering, some problems to be solved include:(1) source and ethics of seed cells;(2) immunological rejection fol owing cellproliferation and transplantation;(3) stability and oncogenicity of transplanted cells;(4) degradation rate, optimal porosity, tube thickness and shape;(5) repair timing for in vitro tissue-engineered nerve construction;(6) local release and regulation of various neurobiological factors. With the development of science, many patients with nerve injuries can profit from the solve of these problems.
