Journal of Chinese Physician 2012;(11):1493-1496
Objective To study the expression of MMP-9 in epatocellular carcinoma (HCC) and the relationship between its expression and clinical pathological characteristics.Methods Specimens taken from 67 fresh resected HCC and 16 normal liver tissues were selected.Tissue sections were stained by EnVisionTM immunohistochemistry with anti-MMP-9 monoclonal antibodies.The expression of MMP-9 in HCC and the relationship between its expression and clinical pathological characteristics were analyzed with x2test,t test and rank-sum test.Results The positive ratio of MMP-9 in HCC tissues was 58.21%,it was obviously higher than that of normal liver tissues (12.5%,x2 =10.80,P < 0.01).The expression of MMP-9 in the metastatic HCC tissues was significantly higher than that in the non-metastatic HCC tissues (40.18 vs 26.38,P <0.01).Conclusions The positive ratio of MMP-9 expression revealed that the expression of MMP-9 increased obviously in the HCC,and that its expression in the metastatic HCC tissues significantly increased relative to the non-metastatic tissues.It suggests that MMP-9 might decompose and destroy the extracellular matrix and cell membrane around HCC cell surface,and then promote invasion and metastasis of HCC.
4.Role of EP_2 in synaptic transmission in dentate gyrus of hippocampus
Journal of Xi'an Jiaotong University(Medical Sciences) 2010;31(1):59-62
Objective To evaluate the role of EP_2 in synaptic transmission in dentate gyrus of hippocampus. Methods Field excitatory post-synaptic potentials (fEPSP) were recorded at the perforated path-granule neurons in dentate gyrus in vitro. Results ① Butaprost, an agonist of EP_2, enhanced the synaptic transmission in dentate gyrus and decreased the paired-pulse ratio, and these effects were reversed by bath application of AH6809 (EP_2 antagonist). ② Application of Forskolin alone or with AH6809 elevated the slope of fEPSP. ③ The Butaprost-induced responses were mediated via PKA, ERK and IP_3 signal pathways. Conclusion Multiple signal pathways were involved in the EP_2 activation-mediated enhancement of synaptic transmission.
5.COX-2 modulates Δ~9-THC-induced inhibition of LTD in CA1 area
Journal of Xi'an Jiaotong University(Medical Sciences) 2009;30(6):701-704
Objective To explore the role of cyclooxgense-2 (COX-2) in tetrahydrocannabinol (THC)-induced inhibition of long-term depression (LTD) in CA1 area in vitro. Methods The hippocampal slices were prepared at 24 h after intraperitoneal injection of Δ~9-THC (10 mg/kg) or COX-2 inhibitor NS398 (10 mg/kg). Field excitatory post-synaptic potentials (fEPSP) were recorded in the stratum radiatum of the CA1 area in vitro to observe the effect of NS398, a selective inhibitor of COX-2, on the THC-induced inhibition of LTD and THC's effect on membrane excitability in pyramidal neurons by using the whole-cell patch clamp technique. Results ① Low-frequency stimulation (1 Hz, 15 min) induced-LTD in CA1 area was significantly attenuated by Δ9-THC. ② Δ~9-THC did not affect the basal synaptic transmission and membrane excitability (including membrane resting potentials, input resistance and firing property). ③ THC-induced inhibition of LTD was reversed by NS398. ④ THC-induced inhibition of LTD was robustly impaired in COX-2 knockout mice. Conclusion THC-induced inhibition of LTD in CA1 area was mediated via COX-2.

Chinese Journal of Tissue Engineering Research 2016;20(26):3923-3928
BACKGROUND:64-slice CT reconstruction technique for tibial plateau fractures hasobtainedsatisfactory results. This technology can reconstruct three-dimensional fracture relations, provide more scientific positioning and navigation standards for physicians, and improve the clinical cure rate. However, in the clinic, navigation method of 64-slice CT reconstruction techniques for tibial plateau fractures lacks a unified standard. OBJECTIVE:To study the navigation method and effect of 64-slice CT reconstruction in tibial plateau fractures. METHODS:A total of 44 patients with tibial plateau fractures were enroled in this study, including 27 males and 17 females, at the age between 21 and 74 years old. These patients were randomly divided into two groups (n=22). The control group underwent navigation method according to physician’s experience. The test group underwent navigation method according to 64-slice spiral CT scan results. Healing time, ful weight-bearing time, knee motion rangeat1 year postoperatively, the recovery ofknee functionat1 year postoperatively and adverse reaction were compared between the two groups. RESULTS AND CONCLUSION:(1) No significant differences in ful weight-bearing time and knee motion rangeat1 year postoperatively were detected between the two groups (P> 0.05). Healing time was significantly shorter in the test group than in the control group (P< 0.05). (2) The excelent and good rate of knee joint was 100% at 1 year postoperatively in the test group, which was significantly higher thanthe control group (81%) (P< 0.05). (3) The complication rate was significantly lower in the test group (8%) than in the control group (18%) (P< 0.05). (4) These results indicate that the effect of 64-slice CT reconstruction for navigation in tibial plateau fractures was ideal, could clearly simulate the pedicle screw fixation channel, visibly display anatomic characteristics of tibial plateau fractures, improve internal fixation accuracy, and improve repair effect.
