Malignant obstruction in the ileocecal region treated by self-expandable stent placement under the fluoroscopic guidance: A case report.

Background: Malignant tumors of the ileocecal region often cause intestinal obstruction. Emergency surgery is the main treatment for patients presenting with an obstruction. However, this procedure is associated with a high mortality rate and frequent complications.

Current Genetic Structure Analysis of Leopard Cats Reveals a Weak Disparity Trend in Subpopulations in Beijing, China.

In the face of habitat shrinkage and segregation, the survival of wild cats looks bleak. Interpreting their population genetic structure during habitat fragmentation is critical in planning effective management strategies. To reveal the segregation effects of road construction and human settlements on the population genetic structure, we analyzed non-invasive fecal DNA samples from leopard cats () from five nature reserves in mountainous areas around Beijing.

Factors Related to Instrumentation Failure in Titanium Mesh Reconstruction for Thoracic and Lumbar Tumors: Retrospective Analysis of 178 Patients.

Purpose: To investigate risk factors for instrumentation failure (IF) in titanium (Ti) mesh reconstruction for thoracic and lumbar tumors.

Patients And Methods: The clinical data of patients with thoracic or lumbar tumors who received Ti mesh reconstruction via the posterior approach in our hospital from 2013 to 2018 were analyzed retrospectively. The observation indexes included sex, age, BMI, the vertebra resection mode, the number of resected vertebral segments, application of bone cement, radiotherapy, chemotherapy, revision or primary surgery, and primary tumor metastasis.

Non-invasive genetic analysis indicates low population connectivity in vulnerable Chinese gorals: concerns for segregated population management.

Detailed information on the size and genetic structure of wildlife populations is critical for developing effective conservation strategies, especially for those species that have suffered population decline and fragmentation due to anthropogenic activities. In the present study, we used a non-invasive approach combining fecal pellet sampling with mitochondrial DNA and nuclear DNA microsatellite marker analysis to monitor and compare the population structure of the Chinese goral () in Beijing and northeast Inner Mongolia in China. Of the 307 fecal samples confirmed to be from , 15 individuals (nine females and six males) were found in the Beijing population and 61 individuals (37 females and 24 males) were found in the Inner Mongolian population.

[Population, distribution and food composition of wolves (Canis lupus) at Saihanwula Nature Reserve, Inner Mongolia].

To provide initial value for population restoration and management of wolves (Canis lupus) in the wild, line transect survey and fecal analysis method were used to study the population ecology of wolf at Saihanwula National Nature Reserve, Inner Mongolia. The results revealed that the population number was at least seven within the reserve and population density was 4.18+/-2.
