Objective To investigate the distribution modes of NOS nerves and interstitial cells of Cajal (ICCs) in myenteric plexus of human fetal intestine. Methods Small intestine samples from 12 fetuses were collected for the preparation of whole mount preparations and cryo sections examined by immunocytochemistry for c kit receptor tyrosine kinase and histochemistry for NADPH diaphorase. Results ICCs associated with the myenteric plexus in the fetal small intestine were observed in the shape of spindle or ovoid with two to three slender processes forming an independent and complete cellular network. While NOS positive nerves, which constitute the main neuronal component of ganglia, connecting strands, and nerve fibers, were found within the circular muscle layer and myenteric plexus of the small intestine and the latter was especially rich of this kind of nerves. Most of these positive neurons were Dogiel I type neurons and they often gathered in cluster in the ganglia. Each ganglion contained several to dozens of NOS positive neurons. Although no colocalization of ICCs and NOS positive nerves was found by double staining of whole mount preparations and cryo sections, they were closely distributed. Conclusion Our results indicate that NO released by myenteric plexus, an inhibitory neurotransmitter, may possess the function of regulating ICCs and smooth muscle in late stage of the fetus.

Objective Hepatitis C virus patients are often accompanied by insulin resistance and diabetes.To probe the relative factors of abnormal glycometabolism in chronic HCV infections.Methods A total of 1 039 treatment-naive patients that were confirmed chronic HCV infected were enrolled in the study.The demographics,biochemical index parameters and other data about liver function and HCV viral load were got from infectious disease department of Jurong Pepole's Hospital in China.Results A total of 140 (13.5％) patients were diagnosed with some forms of abnormal glycometabolism.The body mass index (BMI) (x2 =9.231,P =0.010),waist circumference (x2 =7.984,P =0.018),systolic blood pressure (x2 =16.366,P ＜0.001),diastolic blood pressure (x2 =13.970,P =0.001),alanine aminotransferase(ALT) (x2 =4.809,P =0.028),HCV-RNA viral load (t =-3.818,P ＜0.001) were significantly different between non-diabetic HCV patients and abnormal glycometabolism patients.Multivariate logistic regression analysis showed that ALT(OR =2.986,95％ CI:1.171-7.615) and HCV-RNA viral load (OR =2.061,95％ CI:1.165-3.644) were found as risk factors in multivariate regression analysis for patients with chronic hepatitis C who had abnormal glucose metabolism.Conclusions Chronic hepatitis C patients with higher ALT and HCV-RNA level were more probably to suffer from abnormal glycometabolism.In order to find potentially novel risk factors of HCV with abnormal glucose metabolisn,further studies about genetic and other clinical factors need to be processed.

BACKGROUND:Many scholars have developed a variety of dynamic elastic spine fixator. After biomechanical research, animal experiments and clinical application found that no one elastic spine fixator was general y recognized clinical y. OBJECTIVE:To compare the stress difference between“X”-shaped spine dynamic fixation and traditional pedicle screw fixation. METHODS:Three-dimensional finite element models of“X”-shaped spine dynamic fixation and traditional pedicle screw fixation were established according to adult spine imaging data. Mechanical differences in vertical compression, flexion, extension, lateral bending and rotation were compared between the two groups. RESULTS AND CONCLUSION:The stress at vertical compression was lower than that at flexion, extension, lateral bending and rotation in both groups. The stress at“X”-shaped spine dynamic fixation mainly focused on“X”-shaped connecting rod, but the stress of traditional pedicle screw fixation mainly focused on conjunction of screw-rod. Moreover, the stress of the screw of“X”-shaped spine dynamic fixation was significantly less than that of traditional pedicle screw fixation (P<0.001). These results suggest that“X”-shaped spine dynamic fixation system can share stress of screws and reduce the postoperative stress concentration compared with traditional pedicle screw fixation.

Objective To analyze the positive rate of specific distribution characteristics in Rh blood group antibody,analyze the clinical significance of Rh blood group antibody and rules.Methods The micro column gel anti globulin technique was used to screen and identify irregular red blood cell antibodies,for patients with Rh blood group antibody,monoclonal anti-D,anti-C,anti-c, anti-E,anti-e were used to identify Rh blood group antigen to confirm the accuracy of detection.The antibody titer,Ig-type and 37℃ reactive were used to determine its clinical significance.Through asking pregnancy history,history of blood transfusion,under-standing whether the same specificity of the antibody in maternal plasma if the patient was newborn,the causes of antibody were an-alyzed.Results In 109 000 patients,Rh blood group antibodies were detected in 96 cases,the positive rate was 0.088%,which has a history of pregnancy in 68 cases,5 cases had history of blood transfusion,both pregnancy history and history of blood transfusion in 6 cases,1 7 cases of neonatal maternally derived antibody.Antibody specificity:65 cases of anti-E(67.710%),12 cases of anti-cE (12.500%),8 cases of anti-D (8.330%),7 cases of anti-c(7.291%),2 cases of anti-C (2.083%),2 cases of anti-e(2.083%).96 cases of Rh blood group antibodies were IgG or IgG+IgM class,37 ℃ reaction could be with the corresponding antigen of red blood cell,antibody titer between 4-2 048.Conclusion Anti-D detection rate shows a trend of gradually decreasing.In Rh blood group antibody detection,anti-E and anti-cE account for an absolute majority.Alloimmune caused by pregnancies and blood transfusion is the main reason of Rh blood group antibody production from Rh blood group antibody.Neonatal maternal passive getisa Rh-HDN is the main pathogenic antibody.
