Wnt signaling pathway has a critical role in differentiation, proliferation, supersession and metabolism of osteocyte. Although the principal components are relatively simple, however, the numerous components consisted of Wnt signaling participate in the reaction, including several LRPs ( low density lipoprotein receptor-related protein,LRP) , 19 different Wnt proteins and 19 different FZDs( frizzled receptor, FZD) , and non-canonical Wnt signaling and multiple inhibitors of Wnt signaling.The Wnts linked to mem-brane coreceptor and activated downstream of canonical Wnt signaling or non-canonical Wnt signaling, In addition, different Wnts had different roles in differentiation, bone formation and bone absorption of osteocyte.This review aims to understand the relationship be-tween Wnt signaling and osteocyte metabolism and bone diseases, by analyzing a variety of factors and the process of Wnt protein and Wnt signaling pathway in activity of osteocyte.

Objective With the development of minimally invasion and the popularization of arthroscopy the technology of ar-throscopy has been widely applied for the treatment of acute and the safety of this has been validated.To analyze the clinical effect of ar-throscopically assisted double Endobutton plate reconstruction of coracoclavicular ligament in the treatment of acute acromioclavicular joint dislocation. Methods From November 2013 to December 2014, a total of 23 patients with Rockwood type III,Ⅳ,Ⅴshoulder joint dis-location were included, all cases was treated by arthroscopic double Endobutton fixaton technique.Patients were followed up for 6 to 18 months.The changes of shoulder joint forward elevation and external rotation, Japanese Orthopaedic Association score(JOA), and Visual Analogue score( VAS) of acromioclavicular joint in both perioperative and postoperative were recorded. Results The mean follow-up time was (9.3 ±2.4) months ( range from 6 to 18 months),and mean time from injury to surgery was(10.1 ±3.2)days.The therapeutic effects were achieved in all patients after the arthroscopically assisted double Endobutton plate reconstruction.All the measurements, in-cluding the mean forward elevation JOA scores before and after fixation (71.0 ±5.4 vs 93.5 ±3.6), and mean VAS scores (4.6 ±1.0 vs 1.9 ±0.9), mean forward elevation [(102.5 ±8.6) degrees vs (144.3 ±6.3) degrees], and mean external rotation[(107.1 ±6.2) de-grees vs (149.6 ±7.5) degrees] improved significantly (P<0.05) after the treatment. Conclusion Arthroscopic double Endobutton fixaton technique could provide an effective immobilization of shoulder and acromioclavicular joint, thus improving the function of the joint and achieving an excellent effect in the treatment of acute acromiocla-vicular joint dislocation.

BACKGROUND:Lithium chloridecan promote the proliferation and osteogenic capacity of bone marrow mesenchymal stem cels in the necrotic region after avascular necrosis of the femoral head, which has become an issue of concern. OBJECTIVE:To compare the advantages and disadvantages of bone marrow stem cel transplantation combined with lithium chloride in the treatment of rabbit femoral head necrosis. METHODS: Passage 2 bone marrow mesenchymal stem cels from 1-week-old New Zealand rabbits were cultured in 0, 5, 10, 20, 40 mmol/L lithium chloride. Forty-eight healthy adult New Zealand rabbits were selected to make femoral head necrosis models in the right femoral head using liquid nitrogen freezing method and then randomized into four groups: model group with no implantation; lithium chloride group given lithium chloride treatment at 3 days after modeling; cel transplantation group given gelatin sponge implantation and bone marrow mesenchymal stem cel suspension injection into the femoral head after modeling; combined group given bone marrow mesenchymal stem cel suspension injection and lithium chloride treatment. Intraperitoneal injection of lithium chloride (45.2 mg/kg) was given daily beginning at the postoperative 3rdday, and the treatment duration was 4 weeks. RESULTS AND CONCLUSION:Lithium chloride at 10 mmol/L had the maximum effect on the proliferation of rabbit bone marrow mesenchymal stem cels, and if the concentration of lithium chloride was > 10 mmol/L, the promotion role of lithium chloride began to decline. After combined treatment, the morphology of the femoral head was restored a little, with increased bone density and thickened trabecular bone; the level of β-catenin in the femoral head was significantly increased in the combined group compared with the cel transplantation group or the lithium chloride group. These findings show that bone marrow stem cel transplantation combined with lithium chloride treatment can promote the recovery from femoral head necrosis by increasing bone mass of the trabecular bone and bone density of the femoral head in the necrotic region.

Objective To explore the correlation of the TIAM2 functional gene mutations with the bleeding events in patients with coronary heart disease who undergone PCI and postoperative taken anti-platelet drug clopi-dogrel. Methods One hundred and twenty Chinese Han patients who had undergone PCI and postoperative taken anti-platelet drug clopidogrel were orderly enrolled from Guangdong General Hospital. Followed for 6 months after PCI, PCR sequencing was applied to test TIAM2 promoter region genotyping assay. Results After follow-up six months , 113 cases were remained lost of 7 cases , , including 19 cases with bleeding and 94 cases without bleed-ing; Bleeding risk in patients with diabetes mellitus (OR=3.115) or taking statins (OR=11.539), may be high, but there was no significant difference (P > 0.05); TIAM2 promoter region had three variants (c.3168+3116C>T, c.3168+3261A>G,c.3168+3596A>C), including wild-type, heterozygous, and homozygous. The probability of pa-tients with bleeding were 36.84%, 52.63%and 10.53%, and there is a certain chain of state , but the genotype was not significantly correlated with bleeding events of clopidogrel antiplatelet therapy (P>0.05). Conclusion Clopi-dogrel antiplatelet therapy bleeding events were not significantly correlated with TIAM2 functional gene mutation.

BACKGROUND:Previous therapies for diabetic foot are not ideal with large cost, and moreover, amputation is often required. OBJECTIVE: To perform the Ilizarov bone transport in the treatment of patients with diabetic foot (Wanger grades 3-4), and to observe the limb salvage conditions. METHODS: Eighteen patients with diabetic foot, Wanger grades 3-4, admitted in the Department of Bone and Joint Surgery, First Affiliated Hospital of Guangxi Medical University from December 2013 to June 2015 were enroled in this trial. Al of patients were subjected to Ilizarov bone transport. RESULTS AND CONCLUSION: Al the 18 patients were folowed up for 3 to 20 months, and presented with ulcer healing. Scores on ankle-brachial index and 10-g nylon line test were both increased significantly in the patients after treatment, but the visual analog scale scores were reduced. These findings indicate that the Ilizarov bone transport is an effective method for treating ulcer of diabetic foot at Wanger grades 3-4.
