BACKGROUND: There is lack of effective method for treating humerus nonunion, lilac plate can maintain the compact contact between fracture end and bone graft, accelerate bone union, as well as provide stability for bone union. OBJECTIVE: To evaluate the clinical effects of treating humerus nonunion by using lilac bone graft as plate combined with the external fixation.METHODS: Thirteen patients with nonunion of the humorous at Department of Orthopedic Trauma Surgery, Jinan Command General Hospital of Chinese PLA were selected, including 11 males and 2 females, aged 20 51 years, mean aged 35.5 years. All the patients were treated with Uiac bone graft and screws combined with the mono lateral external fixation. The bone healing was observed by X-ray film. Shoulder function and complications were measured by Neer score.RESULTS AND CONCLUSION: All patients were followed up for 7-64 months, mean 38 months. Bony union was achieved in all patients within 6-10 months (mean 8.1 months). The activity function of shoulder and elbow was normal; and Neer scores were 71-96 (mean 87 scores). No infection, pain, prevalent fracture or nonunion occurred. The results demonstrated that using lilac bone graft as plate combined with the mono lateral external fixation is a good salvage operation for nonunion of the humerus.

OBJECTIVE:To observe the curative efficacy of Ginseng and aconiti praeparatae injection in combination with prostaglandin E1 for diabetic feet.METHODS:A total of 40 patients with diabetic feet were randomized to receive Ginseng and aconiti praeparatae injection in combination with prostaglandin E1 plus basic therapy(treatment group)or to receive prostagla-ndin E1 plus basic therapy(control group).The cure rate of the ulcer of the diabetic feet,the vascular ultrasonography and blood coagulation indexes in two groups before and after treatment were evaluated.RESULTS:There were significant differences between the treatment group and the control group in total response rate(90.0% vs.60.0%)(P

Objective The anterior-lateral defect of foot that lost one of the three supporting point of foot can lead to collapse of the lateral longitudinal arch, overload of the first metatarsal heads, and painful callus formation. It is meaningful to investigate the effect of reconstructing the lateral forefoot defect with pedical fibular osteoseptocutaneous flap. Methods From March 1989 to June 2008, there were 38 patients with anterior-lateral defect of foot were constructed. The supporting point with the local distal based pedical fibular osteoseptocutaneous flap was constracted. Results All the 38 flaps survived. All 38 patients had been followed up from 6 months to 10 years (mean 23.5 months) postoperatively. The constructed supporting point of the foot was functional. The patients could walk freely with no pain, and was satisfied with the operation. Assessed with the rating system for foot and ankle established by the American Orthopaedic Foot And Anke Society, 8 patients got a score above 85, 23 patients between 75 to 85, 7 patients between 60 to 75. Conclusion It is effective that transferring local distal based pedical fibular osteoseptocutaneous flap to repair the anterior-lateral defect of foot.

ObjectiveTo reveal the targets and molecular mechanisms of the action of Qiangxin Decoction （强心汤） for the treatment of chronic heart failure based on the combination of network pharmacology and molecular docking. MethodsThe active ingredients of Qiangxin Decoction were retrieved from TCMSP database， and the targets of chronic heart failure were screened by searching GeneCards， OMIM， TTD， PharmGkb， and DrugBank databases， and the intersections were taken to obtain the intersecting targets of Qiangxin Decoction for the treatment of chronic heart failure. STRING platform was used to construct the protein-protein interaction network （PPI）， Cytoscape 3.8.0 software was used to calculate the network topology to screen the core targets， and R 4.2.3 was used to construct the “active ingredient-target” network by analyzing the GO enrichment analysis and KEGG pathway enrichment analysis. AutoDock 1.5.7 was used for molecular docking to predict the binding performance of active ingredients and core targets. ResultsSeventy-five intersecting targets were identified for the treatment of chronic heart failure with Qiangxin Decoction， among which the core targets were estrogen receptor 1 （ESR1， degree value=7）， nuclear receptor coactivator 1 （NCOA1， degree value=8）， glucocorticoid receptor （NR3C1， degree value=7）， and nuclear receptor coactivator 2 （NCOA2， degree value=7）. GO enrichment analysis showed that the top 3 items with the smallest P value in molecular function were G protein-coupled amine receptor activity， postsynaptic neurotransmitter receptor activity， and neurotransmitter receptor activity （P＜0.01）； the top 3 items with the smallest P value in biological process were adenylyl cyclase-activated adrenergic receptor signaling pathway， adrenergic receptor signaling pathway， and adenylyl cyclase-regulated G protein-coupled receptor signaling pathway （P＜0.01）； the top 3 items with the smallest P values in cellular composition were components of the postsynaptic membrane， synaptic membrane， and presynaptic membrane （P＜0.01）. KEGG enrichment analysis showed that the top 5 key signaling pathways were neuroactive ligand-receptor interactions， calcium signaling pathway， dopaminergic synapses， cocaine addiction， and cyclic guanosine monophosphate-protein kinase G （cGMP-PKG） signaling pathway. The molecular docking results showed that lignans and isoflavones had lower binding energies and more structural stability with the four core targets （ESR1， NCOA1， NR3C1， NCOA2）. ConclusionThe treatment of chronic heart failure by Qiangxin Decoction was associated with neuroactive ligand-receptor interactions， calcium signaling pathway， dopaminergic synapses， chemoattractant-receptor activation， cGMP-PKG signaling pathway， lipids and atherosclerosis， and cAMP signaling pathway， and lignans and isoflavones may be the core active compounds in its treatment of chronic heart failure.
