A small juvenile turtle is described from the Early Cretaceous Jehol Biota, shedding light on the juvenile morphology and ontogeny of . Several juvenile features are uncovered, such as a small and circular carapace (less than half of the adult), wide vertebral scales, and lateral carapacial fontanelles. In contrast to the adult morphology, which has an oval carapace, closed lateral fontanelles, and longer vertebrals 2-4, the juvenile of is more comparable to that of , except for earlier occurrence of the well-ossified carapace of the latter.

Objective: This study was designed to explore the factors influencing local recurrence and survival for low rectal cancer with pT1-2NxM0 stage after an abdominoperineal resection (APR).
Methods: Data of 429 patients confirmed to have pT1-2NxM0 after APR were reviewed.
Results: The recurrence rate in patients with intraoperative perforation, less than 12 lymph nodes (LNs) harvested, T2 staging, and positive circumferential resection margin (CRM) was 25.
The present study aimed to identify the association between microRNA (miR/miRNA)-449a, the cyclin-dependent kinase (CDK)6 protein and gastric carcinoma, and discuss the effect of miR-449a on the expression of the CDK6 protein. Quantitative (q)PCR and western blot analysis were used to analyze the expression of the miR-449a and the CDK6 protein in gastric carcinoma and tumor-adjacent normal tissues. The real-time cell analyzer and the DAPI staining test were used to monitor the different miR-449a levels regulating the proliferation and apoptosis of the MGC-803 cell line.

Patients may complain of abdominal pain, fever or other symptoms. No significant decrease has been identified in the hepatic function or elevation of α-fetoprotein, which differentiates UESL from primary carcinomas of the liver.

However, application of previously developed vaccines for preventing CDI has been limited due to various reasons. Here, we developed a recombinant Lactococcus lactis oral vaccine and evaluated its effect on a C.

Small interfering RNA (siRNA) seem to be a promising tool for treating HBV, but had no effect on the pre-existing HBV covalently closed circular DNA. Because it is very difficult to thoroughly eradicate HBV with unique siRNAs, upgrading the immune response is the best method for fighting HBV infection.

Objective: To explore the treatment of acute obstructive suppurative cholangitis (AOSC) with multiple organ failure (MOF).
Methods: Twenty-five patients with AOSC complicated by MOF underwent non-surgical comprehensive therapies, including endoscopic naso biliary drainage (ENBD), flushing and antibiotic perfusion through the naso biliary catheter. The alterations of the levels of serum total bilirubin and common bile duct diameter were measured both preoperatively and postoperatively, with retrospective analysis of the patients' clinical record.

AIM:To establish an experimental model of stress ulcer produced by explosive noise, and to probe into its mechanism and protection.METHODS:The country standard Wistar white rats were randomly divided into control group(n =8), which were neither stimulated nor protected, and stimulating group (divided into subgroups A, B and C, including 8 rats each which were decapitated to draw blood for test immediately, 12 hours and 24 hours after stimulation) and prevention group (divided into subgroups A, B and C, having 8 rats each, subgroup A was given cimetidine, B anisodamine and C both drugs). Firing noises of submachine guns were used as inflicting factor.
