OBJECTIVETo compare the clinical efficacy on the motor impairment of knee joint after tracture operation between the combined therapeutic method of relaxing needling manipulation and exercise therapy and the simple exercise therapy.

METHODSSixty-four patients after the operation for the fracture of femoral shaft were randomized into a relaxing needling combined with exercise therapy group (group A) and an exercise therapy group (group B), 32 cases in each one. In the group A, the relaxing needling manipulation was applied to the local painful area of knee or the stiff soft tissues. Additionally, the exercise therapy was used in combination. In the group B, the exercise therapy was applied simply. Hospital for special surgery (HSS) pain score, the range of movement (ROM) of knee joint and Lysholm score were compared before and 60 days after treatment in the patients of the two groups. The efficacy was compared between the two groups.

RESULTSAfter treatment, HSS pain score, ROM and Lysholm score were all improved in the two groups, presenting the significant differences as compared with those before treatment (all P<0. 05). The results in the group A were better than those in the group B (all P<0. 05). The total effective rate was 96. 9% (31/32) in the group A, which was better than 75. 0% (24/32) in the group B (P<0. 05).

CONCLUSIONThe combined therapeutic method of relaxing needling manipulation and exercise therapy achieves the significant efficacy on the motor impairment of knee joint after the operation for the fracture of femoral shaft, superior to the simple exercise therapy.

OBJECTIVETo compare the effects on joint dysfunction after meniscal suture surgery between rehabilitation training combined with modified-acupuncture and simple rehabilitation training.

METHODSSeventy-one patients with meniscal suture surgery were randomized into an observation group (=36) and a control group (=35). Patients in the observation group received modified-acupuncture combined with rehabilitation training. Acupuncture for 8 weeks were at Zutonggu (BL 65), Shugu (BL 66), Neiting (ST 44), Xiangu (ST 43), Xiaxi (GB 43), Zulinqi (GB 41), Dadu (SP 2), Taibai (SP 3), Xingjian (LR 2), and Taichong (LR 3), once a day for continuous 6 days with 1 day for rest. Patients in the control group received simple rehabilitation training for continuous 8 weeks. The training included quadriceps femoris, range of knee joint motion and motion and limb walking on the affected side. The effect score for meniscus injury after treatment from Japanese Orthopaedics Association (JOA) and visual analogue scale (VAS) score were recorded before and after treatment. The effects were compared in the two groups.

RESULTSAfter treatment, the VAS and JOA scores were improved in the two groups (all<0.05), with better results in the observation group (both<0.05). The effective rate was 91.7% (33/36) in the observation group, which was better than 80.0% (28/35) in the control group (<0.05).

CONCLUSIONRehabilitation training combined with-acupuncture achieve better effect than simple rehabilitation training for joint dysfunction after meniscal suture surgery.

OBJECTIVE: To investigate the effect of acute myeloid leukemia cells in leukemia-microenvironment on proliferation and apoptosis of bone marrow-derived mesenchymal stromal cells (BM-MSC). METHODS: Acute myeloid leukemia (AML) murine models overexpressing MLL-AF9 were established. The number of BM-MSC of wild type (WT) and AML-derived mice were analyzed by flow cytometry. Morphology and growth differences between WT and AML-derived BM-MSC were analyzed by inverted fluorescence microscope. Proliferation and apoptosis of BM-MSC between these two groups were detected by Brdu and Annexin V/PI. RESULTS: Compared with WT-derived BM-MSC, the number and proliferation rate of AML-derived BM-MSC significantly increased (P<0.01, P<0.001), while apoptosis rate decreased (P<0.05). When cultured in vitro, BM-MSC grew faster under conditional medium. CONCLUSION AML cells can promote proliferation and inhibit apoptosis of BM-MSC.
