Objective To apply the WeChat in family rehabilitation after anterior cruciate ligament (ACL) reconstruction. Methods 126 patients accepted ACL reconstruction using quadrupled semitendinosus and gracilis tendons were divided into observation group (n=69) and control group (n=57). The control group received conventional rehabilitation program, and the observation group joined the WeChat group. They were assessed with knee range of motion (ROM), knee stability test, thigh perimeter, Lysholm score and the International Knee Documentation Committee (IKDC) score 3 and 6 months after operation. Results There was a significant difference between groups in ROM of knee flexion (P<0.05) 3 and 6 months after operation, but not in ROM of knee extension (P>0.05). There was no significant difference in thigh perimeter 3 months after operation, but it was significant 6 months after operation. There was significant difference in Lysholm score and IKDC score (P<0.05), but not in the joint stability (P>0.05). Conclusion Direction of rehabilitation with the WeChat Group can significantly improve the compliance, accelerate the rehabilitation process and reduce complications in patients after ACL reconstruction.

Objective:To define the expression levels of MDM2 gene in nasopharyngeal carcinoma (NPC)and its relationship with p53 protein expression and EB virus latent infection. Method :MDM2 gene expression atmRNA and protein levels,p53 protein and EB virus DNA were detected by nonradioactive in situ hybridization(ISH) ,immunohistochemistry(IHC) and polymerase chain reaction (PCR) separately in 46 cases of NPC tissuesand 12 cases of chronic inflammation of nasopharyngeal epithelium (CINE). Result: Fourteen cases of NPCshowed MDM2 mRNA and protein overexpression, 38 cases were p53 protein positive,and 43 cases were EBV-DNA positive. Neither MDM2 nor p53 protein was expressed in any case of CINE. MDM2 expression was signifi-cantly related to p53 protein expression ( P ＜0. 05), but not to EB virus latent infection in NPC. Conclusion:MDM2 gene may play an important role in the pathogenesis of NPC through interacting with p53 protein.

OBJECTIVETo evaluate the effects of treadmill running exercise of different intensity on early repair of full-thickness defects on the patellofemoral articular surface and the changes in the expressions of matrix metalloproteinase-3 (MMP-3) and tissue inhibitor of metalloproteinase-1 (TIMP-1) in SD rats.

METHODSTwenty-four male SD rats with full-thickness defects on the patellofemoral articular surface were randomly assigned into sedentary control (SED) group and low-, moderate- and high-intensity running groups (LIR, MIR, and HIR groups, respectively). The running groups were trained on treadmill for 6 consecutive weeks. Blood samples were collected to detect serum MMP-3 and TIMP-1 levels using ELISA before and after the experiment, and the femoral trochlea were collected to assess tissue repair by gross appearance scoring and O Driscoll histological scoring with Safranine O-Fast Green staining and Toluidine blue staining.

RESULTSIn rats in SED group, the defect was filled with hyaline articular cartilage-like tissues, as compared to fibrous tissues in LIR and MIR groups and subchondral bone damage in HIR group. The SED group scored the highest and HIR group the lowest among the 4 groups in gross appearance scoring and O Driscoll histological scoring. No significant differences were found in MMP-3 or TIMP-1 levels among the groups before training (P>0.05), but after 6 weeks of training, serum MMP-3 and TIMP-1 levels differed significantly among the 4 groups (P<0.05), and all the 3 running groups had a significantly higher MMP-3 level than the control group (P<0.05). After the 6-week training, TIMP-1/MMP-3 ratio was significantly higher in SED group than in the 3 running groups, and was the lowest in HIR group.

CONCLUSIONBoth low- and moderate-intensity exercise failed to promote resurfacing of full-thickness cartilage defects on the patellofemoral articular surface in rats, and high-intensity exercise even induces subchondral bone damage. The expression of MMP-3 and TIMP-1 is related to exercise, and the TIMP-1/MMP-3 ratio reflects the extent of tissue repair.
