The authors adopted an auto control experimental research on 18 male adult dogs with 36 sides of femoral heads and necks which were divided into two groups. They were separately made models of old fracture of femoral neck and avascular necrosis of famoral head. Two wecks later, The free fibula with microvascular an astomosis was tranplanted. All experimental dogs were examined with X-ray, pathohitology, electron microscopy, 99~mTc-MDP scanning and tetracycling labeling after operation.The experiment showed that the free fibular graft with mierovascular anastomosis could provided a new system of vascula supply to the injured femoral head. The hard free fibula and the metallic internal fixation were inserted in femoral head and neck. After the Operation, in the fracture area the fibula formed a bone-bridge which not only diminished the stress force but also prevented rotation displacement of the bone fracture The periosteum of the transplanted fibula also took part in the repair course of avascular nerosis of femoral head.

Objective To investigate the effect of N-nitro-L-arginine (NO2Arg) on the development of morphine tolerance and dependence.Methods Forty male SD rats weighing (180 ? 18)g were randomly divided into 5 groups for the study of morphine physical dependence and tolerance : group Ⅰ normal saline; group Ⅱ morphine; group Ⅲ morphine + 1 mg?kg-1 NO2Arg; group Ⅳ morphine + 5 mg?kg-1 NO2 Arg ; group Ⅴ morphine +20 mg?kg-1 NO2Arg. Twenty-four male Kunming mice weighing (20.0 ? 2.3)g were randomly divided into 3 groups for the study of psychological dependence: group Ⅵ morphine; group Ⅶ dihydro etorphine; group Ⅷ normal saline. The morphine physical dependence was induced by dose increment. The degree of morphine tolerance was assessed by the pain threshold to heat radiation using tail-flick test. The degree of morphine physical dependence was determined by evaluating the abstinence syndrome precipitated by 4 mg?kg -1 naloxone. The psychological dependence of mice was evaluated by conditioned place preference. Results Consecutive injection of NO2Arg inhibited the development of morphine tolerance in a dose-dependent manner. 5 mg?kg-1 NO2 Arg suppressed most abstinent symptoms of morphine dependent rats. The duration when morphine and dihydro etorphine psychologically dependent mice stayed in the preferred compartment increased significantly from (6.1? 2.0)min and (8.0?0.7)min to (9.3?1. l)min and (9.5 ? 1.2) min by 4 mg?kg-1 NO2 Arg. Conclusion NO2 Arg can inhibit the development of morphine tolerance and dependence and reverse the existing psychological dependence.

Objective: To observe the efficacy of knee-balancing manipulation plus heat-sensitive moxibustion in treating knee osteoarthritis (KOA) and its impact on the expression of C-telopeptide of type Ⅰ collagen (CTX-Ⅰ), tartrate-resistant acid phosphatase 5b (TRACP-5b), A disintegrin and metalloproteinase with thrombospondin motifs 4 (ADAMTS-4), and matrix metalloproteinase 3 (MMP-3). Methods: A total of 134 unilateral KOA patients were randomized into a knee-balancing group, a heat-sensitive moxibustion group, and a joint intervention group. The knee-balancing group received knee-balancing Tuina (Chinese therapeutic massage) manipulation for treatment. The heat-sensitive moxibustion group received heat-sensitive moxibustion treatment. The joint intervention group received the heat-sensitive moxibustion in addition to the knee- balancing manipulation. The intervention period lasted for four weeks. After the treatment, and at the 2-week and 6-week follow-ups, the three groups were assessed using the visual analog scale (VAS) for knee joint pain and Western Ontario and McMaster Universities arthritis index (WOMAC), and clinical efficacy was also evaluated. The enzyme- linked immunosorbent assay was adopted to detect the expression levels of serum CTX-Ⅰ, TRACP-5b, ADAMTS-4, and MMP-3. Results: The knee-balancing group had 44 participants, but one dropped out; there was no dropout case among the 44 participants in the heat-sensitive moxibustion group; among the 46 participants in the joint intervention group, two cases dropped out. After the treatment, and at the 2-week and 6-week follow-ups, the total effective rate was found higher in the joint intervention group than in the knee-balancing and heat-sensitive moxibustion groups (P<0.05). Compared with the baseline, the VAS and WOMAC scores and the serum levels of CTX-Ⅰ, TRACP-5b, ADAMTS-4, and MMP-3 decreased significantly in all three groups after treatment and at the 2-week and 6-week follow-ups (P<0.05). At the same three time points, the VAS and WOMAC scores and serum levels of CTX-Ⅰ, TRACP-5b, ADAMTS-4, and MMP-3 were lower in the joint intervention group than in the knee-balancing and heat-sensitive moxibustion groups (P<0.001). Conclusion: Either used alone or combined, the knee-balancing manipulation and heat-sensitive moxibustion therapy can improve the symptoms and down-regulate the serum levels of CTX-Ⅰ, TRACP-5b, ADAMTS-4, and MMP-3 in KOA patients, producing durable efficacy; nevertheless, a more significant efficacy can be achieved by combining the two methods.
