Objective To observe the effect of glutamine on gut barrier function and antioxidative capacity in rats with radiation damage. Methods A total of 30 healthy Wistar male rats were randomly divided into three groups: control group, GLN enriched group(+GLN) and GLN free group( GLN). Rats in control and GLN group were fed with a basic diet, while 3% GLN was added into the diet of the +GLN group. On the 15th day, rats in GLN and +GLN groups received 9.0 Gy 60 Co ? irradiation in total body. The rate of the gut bacterial translocation and the level of endotoxin, GSH and SOD in the serum were determined at the end of the experiment. Results The rate of bacterial translocation and serum endoxin level were significantly lower in +GLN than in GLN, and GSH and SOD levels in serum were significantly higher in +GLN than in GLN. Conclusion Glutamine supplement is helpful to protect the gut barrier function and improve the antioxidation capacity in rats with radiation injury.

Chronic lymphocytic leukemia (CLL) remains the most common adult leukemia. The recent progress on research of molecular and cellular genetics of CLL promotes the development of the diagnosis, treatment and prognosis for CLL patients. IGVH gene mutation status is the most important prognostic marker for CLL patients. Zeta-chain-associated protein kinase (ZAP-70) can be used as a surrogate marker for IGVH mutation status. CD38 is a type II transmembrane glycoprotein promoting B cell activation and proliferation, which can improve the survival of CLL cells and enhance their proliferation, so it also can be used as an independent prognostic indicator for CLL. Chromosome aberrations are found in more than 80% of CLL cases. The most frequent abnormalities are losses of chromosomal material, with deletions in band 13q14 being the most common. The most common gains of chromosomal material are trisomies 12q. Human leukocyte antigen G (HLA-G) is a non-classical HLA-I gene. Increased expression of HLA-G leads to the malignant progression of CLL, significantly shortens survival, indicating HLA-G might serve as a prognostic marker in CLL. Toll-like receptors (TLA) are important component of natural immunity. The combination of TLR agonists and release chemotherapy, monoclonal antibodies and tumor vaccines would bring a breakthrough for the treatment of CLL.

Objective To investigate the factors predicting endoscopic stone extraction complications during operation and 1 week within operation. Methods The clinical data of 136 patients with common duet stones during endoscopic procedures and 1 week within procedures were collected, and the impacts of the number, size of stones, and the first-attack versus recurrent-attack stone, with or without cholangeitis on the complications during operation and 1 week within operation were analyzed, and the effect of nasobiliary drainage was investigated. Results The success rate in single-stone group was high, the incidences of complications during endoscopy including sphincter hemorrhage, cardiac laceration, hyperamylasemia, acute pancreatitis were significantly lower than those in the multi-stones group ( P < 0. 05 ). The group of < 2 cm stone also had high success rate of stone extraction, the incidences of complications including sphincter hemorrhage, stone impaction, cardiac laceration, hyperamylasemia, acute pancreatitis were significantly lower than those in the ≥2 cm group. The first-attack group had low success rate of stone extraction, the incidences of complications including sphincter hemorrhage, stone impaction, hyperamylasemia, acute pancreatitis and biliary infection were significantly higher than those in the recurrent-attack group. The patients with cholangeitis had low success rate of stone extraction, the incidences of complications including sphincter hemorrhage, hypoxemia, hyperamylasemia, acute pancreatitis and biliary infection were significantly higher than those without cholangeitis. After nasobiliary drainage, the incidences of hyperamylasemia, acute pancreatitis and biliary infection significantly decreased while the incidence of sphincter hemorrhage significantly increased. Conclusions The number, size of stones, and the first-attack versus recurrent-attack stone, symptoms with orwithout cholangeitis could predict the complications of stone extraction;post-ERCP nssobiliary drainage could decrease the complications, but increase the possibility of sphincter hemorrhage.

Objective To assess the value of three-dimensional contrast-enhanced ultrasonography (3D-CEUS) in evaluation of hepatic arteries variants.Methods Both two-dimensional contrast-enhanced ultrasonography (2D-CEUS) and 3D-CEUS were used to assess 30 patients including living donor candidates and patients with upper abdomen tumors.The reference standard was operation or CTA or DSA or MRA,and the accuracy for detecting hepatic artery variants provided by the two methods was evaluated.Arterial anatomic types were defined by using Michels classification.Results The total accuracy for detecting hepatic artery anatomy types by 2D-CEUS was 40.0% (12/30),while 83.3% (25/30) by 2D-CEUS.For convention anatomy types the accuracy on 2D-CEUS and 3D-CEUS were 40.9%(9/22)and 90.9%(20/22),respectively.The difference was statistically significant (P<0.05).For anatomy variants types the accuracy on 2D-CEUS and 3D-CEUS were 37.5%(3/8)and 62.5%(5/8),respectively.No significant difference between these two methods was observed.Conclusion 3D-CEUS was a new method in diagnosis of hepatic arteries anatomy types with practical clinical value in evaluation of the living liver donors.

Objective Detecting of spermatozoal total RNAs by laboratory on chip gel electrophoresis so that it could provide better total RNAs for the sequent experiments, and spur the development of spermatozoal molecular biology. Methods Sperms of healthy adults were collected and then total RNAs were extracted by RNeasy mini kit(QIAGEN), detection and quality control were performed by loboratory on chip gel electrophoresis system. Meantime, the control RNAs were extracted from lymphocytes. Results It was found that there were a plenty of genes expressed in healthy sperms. Electrophoretic graphs showed that the total RNAs of spermatozoal had 2 bands which went ahead a little comparing to the normal somatic cells. The former peak appeared keenness, and the latter was broad and showed like a reversed U. The ratio of them was largely more than 2, no extra peaks were found in electrophoretic graph. Conclusion A simple,intuitionistic method to detect and control the quality of the healthy adults' spermatozoal total RNAs had been successfully constructed by using laboratory on chip gel electrophorosis.
