6.Establishing an intervertebral disc degeneration model using annulus puncture
Chinese Journal of Tissue Engineering Research 2017;21(12):1855-1860
BACKGROUND:Annulus puncture method is commonly reported in the establishment of intervertebral disc degeneration (IDD) models, but there is a lack of comparative studies concerning complete MRI, pathologyical and extracellular matrix changes. Thereafter, a further exploration is imperative. OBJECTIVE:To investigate the feasibility of establishing IDD models using annulus puncture. METHODS:Thirty New Zealand white rabbits were randomly divided into two groups (n=15 per group). In experimental group, through extraperitoneal approach, the L1-2, L2-3, and L3-4 intervertebral space were exposed, and then stabbed by 16-gauge hypodermic needles;while rabbits in sham operated group were only subjected to making and incision but not to puncture. Five rabbits in each group were randomly selected for MRI examination at 4, 8 and 16 weeks after modeling, and were sacrificed through air embolism to obtain the nucleus pulposus. Histological changes were observed by hematoxylin-eosin staining, and the level of proteoglycan was detected by Safranin O staining. RESULTS AND CONCLUSION:In the experimental group, T2-weighted signal in the disc was decreased in a time-dependent manner;an obvious reduction was found at 4 weeks after modeling, and reached the peak at 16 weeks. In contrast, the sham operated group showed no significant changes at each time point. Hematoxylin-eosin staining showed that in the experimental group, cartilage-like cells decreased, while fibroblast-like cells in the disc increased in number and proportion, and extracellular fibers were in disorder;all above changes became obvious at 4 weeks after surgery and the most obvious at 16 weeks, but there were no significant changes in the sham operated group. Safranin O staining revealed that the color of the tissues under puncture became lighter, and this variation became overt at 4 weeks after surgery and the most obvious at 16 weeks. In conclusion, annulus puncture is a reliable method to make IDD models.

Chinese Journal of Rheumatology 2017;21(5):293-296
Objective To discuss the relationship between monocyte CD36 expression and carotid intima-media thickness (cIMT) in rheumatoid arthritis (RA) patients.Methods A total of 207 RA patients were divided into arteriosclerosis group and non-arteriosclerosis groups in accordance with the results of ultrasound in carotid artery,and semi-quantity score was used for cIMT in patients with RA.Risk factors of cIMT in RA patients were analyzed by Spearman correlation and Logistic regression analysis.Results C reactive protein (CRP),triglyceride (TG),tumor necrosis factor (TNF),interleukin-6 (IL-6) and monocyte CD36 expression were found to be statistically different between the two groups (P <0.05).Monocyte CD36 fluorescence intensity was negatively correlated with TNF,IL-6,CRP and cIMT in patients with RA (r=-0.344,P<0.01;r=-0.646,P<0.01;r=-0.160,P=0.021;r=-0.687,P<0.01).Logistic analysis showed that monocyte CD36 was associated with the formation of artery atheromatous plaque in patients with RA [OR=1.580,95%CI (1.057,2.36l),P<0.01].Receiver operating characteristic curve (ROC) curve analysis showed that monocyte CD36 fluorescence intensity was useful when the value with the area under curve was 0.926,the sensitivity and specificity was 83.7% and 82.5% respectively.Conclusion Monocyte CD36 fluorescence intensity is correlated with artery atheromatous plaque in patients with RA,monocyte CD36 fluorescence intensity may be a marker to estimate cIMT in RA patients.
9.Expression and function of P2X purine receptors in the enteric nervous system
International Journal of Surgery 2011;38(1):37-40
P2X receptors are ligand gated ion channels, extracellular ATP is their natural extracellular ligand. When any of the subtypes of P2X receptors and extracellular ATP are combined, P2X channel opens, allowing cations (calcium, sodium, potassium, etc. ) pass through. Enteric nervous system is composed of the gut myenteric plexus and submucosal plexus, in both of which P2X receptors exist, mediating different effects under physiological and pathological conditions. In this paper, the enteric nervous system,P2X receptor distribution and related functions are reviewed in order to further explore the P2X receptor in the diagnosis and treatment of intestinal diseases.
