Clinical efficacy of zoledronic acid combined with calcium in the treatment of primary osteoporosis / 国际生物医学工程杂志

Objective:To investigate the clinical efficacy of zoledronic acid combined with calcium in the treatment of primary osteoporosis (OP).Methods:A total of 180 patients with OP were selected and randomly divided into study group and control group. The two groups of patients were given oral calcium carbonate D3 tablets (Ⅱ), on this basis, the patients in the study group were given zoledronic acid injection. The clinical efficacy was observed after 12 months of the treatment, and the total effective rate was calculated. The bone mineral density, visual analog scale (VAS) of pain, and bone biochemical indexes, including blood calcium (Ca), blood phosphorus (P), bone γ-carboxyglutamate protein (BGP), calcitonin (hCT), collagen type I amino-terminal peptide (P1NP) and collagen type I cross-linked carboxy-terminal peptide (β-specific sequence) (β-CTX) were collected before and after the treatment.Results:The clinical efficacy of the study group was better than that of the control group ( P<0.05). After the treatment, the bone mineral density in the study group was higher ( P<0.05), and the VAS score was lower than that in the control group ( P<0.05). After the treatment, there was no significant difference in serum calcium, serum phosphorus and BGP between the control group and the study group (all P>0.05), the hCT and P1NP levels in the study group were significantly higher than those before the treatment (all P<0.01), and the β-CTX level was significantly lower than that before the treatment ( P<0.01). Conclusions:Zoledronic acid combined with calcium has a good therapeutic effect on OP.

Forearm skin flap with dorsal interosseous artery transplanted in reversal position to repair the skin and soft tissue defect of palm and thumb / 中华急诊医学杂志

Objective To summarize the method of forearm skin flap with dorsal interosseous artery placed by turning the proximal end of the flap to the distal side of the wound to repair skin and soft tissue defect of palm and thumb of hand,and put forward the key points of operation.Methods From 2008 to 2013,the forearm skin flap with interosseous dorsal artery to repair skin and soft tissue defect of palm and the part between thumb and index finger in 20 cases.Dorsal interosseous artery in the forearm is passing through between superficial and deep layers of extensor muscles and sends out 5-13 cutaneous branches to dorsal antebrachium skin.The large skin flap has good blood supply with high survival rate.Results All flaps survived,and good results were achieved in all 20 cases.Conclusion The flap preserved two main arteries from upper limb with good blood supply,and the amount of blood supply of the flap depended on the size of flap,and the wound of donor site can be directly sutured up or covered with free skin graft,thus minimizing the alteration of appearance and function of donor area.

Repair the infra-orbital defect with a rotation flap after basal cell carcinoma resection / 中华整形外科杂志

<p><b>OBJECTIVE</b>To explore the method repairing the infra-orbital defect after basal cell carcinoma resection.</p><p><b>METHOD</b>A facial rotation flap was applied to repair the infra-orbital defects from tumor resection in 28 cases.</p><p><b>RESULT</b>All defects were repaired by this one-stage method, which avoided skin graft, shortened the operation time and minimized the operation trauma. The incision sears are inconspicuous. The facial contours are more satisfactory.</p><p><b>CONCLUSION</b>This technique is simple and effective in repairing the infra-orbital defects, worthy of extensive application.</p>
