[Objective]To investigate etiopathogenisis,modus operandi and rehabilitation in treatment of bone nonunion and residual deformity (cubitus valgus) after humeral lateral condyle fractures in children. [Method]The author retrospective summarized a total of 27 patients diagnosed with humeral lateral condyle fracture follow with bone nonunion and/or cubitus valgus consecutive enrolled in Children’s Hospital of Chongqing Medical University from 2001 to 2006,including 19 cases of male,8 cases of female,16 cases of right humeral lateral condyle fracture and 11 cases of left. The mean age at injured for all the patients (n =27) was 5.6 yr (range 3-10 yr).The mean age at suigical operation for all the patients (n =27) was 9 yr (range 5-14 yr).The average time from injury to operation was 2.8 yr (range 8mon-10 yr).There were three modus operations including direct normal position internal fixation of 7 cases,open reduction following os illium bone graft internal fixation of 11 cases,distant humerus varus wedge shape cut orthopaedic for 9 cases.[Result]Thirteen patients were followed up ranging from 6 month to 2 years,and 14 patients over 2 years. All the patients were achieved union for 8 to 16 weeks after surgery. Elbow deformity had been corrected and function of elbow joint had been recoverd satisfactorily. All of them,excellent rerult were found in 13 cases,good in 11 cases,and poor in 3 cases,the excellent and good rates was 88.9%. None of the cases happened with osteonecrosis,traumatic arthritis and myositis ossificans.[Conclusion]It is common that delay treatment of humeral lateral condyle fractures in children can result in bone nonunion and residual deformity (cubitus valgus) and it is difficult for treatment. Corresponding surgical treatment with different condition and early exercise can improve the appearance and function of elbow joint.

Objective To evaluate the treatment and p re vention of urethral stricture complicated by transurethral vapo-resection of pr ostate (TVP). Methods Retrospective analysis was conduct ed by reviewing medical records and following up the patients under study.Among 3012 patients with benign prostatic hyperplasia treated with TVP, urethral stric ture occurred 4 weeks to 22 months following surgery in 95 cases (3.15 %), inclu ding anterior in 47 (49.5%),posterior in 31 (32.6 %) and bladder neck contractur e or occlusion in 17 (17.9%).Their mean age was 68.7 years (range, 55 to 85 year s). Results The 95 patients were followed up for 4～36 m o nths (mean,14 months).Of them,65 cases underwent conventional dilation, in them 59 (90.8%) were cured and 6 had failure,then turning to internal urethrotomy;19 cases underwent internal urethrotomy plus dilation,in them,13 (68.4%) were cured and 6 had failure,then turning to urethroplasty;17 cases of bladder neck contra cture or occlusion underwent transurethral resection of bladder neck scar tissue ,with a cure rate of 88.2% (15 were cured and 2 experienced failure). Conclusions Urethral stricture is a common complication after TVP. The key points of managing the strictures are patients’ alert,close follow-up and early effective treatment.

Objective To explore the difference of serum free fatty acid(FFA) composition between the patients with the metabolic syndrome(MS) and the patients with high risk for MS(HRMS),and the relationship of FFA composition with their serum glucose.Methods The serum fatty acid profile was measured with the gas chromatography and mass spectrometer(GC/MS)in 159 patients with MS or HRMS and 43 control subjects.Results The contents of unsaturated fatty acid(UFA,C18:2 and C20:3),the ratios of UFA/TFA(total fatty acid),PUFA(polyunsaturated fatty acid)/TFA and PUFA/SFA(saturated fatty acid) were significantly increased in patients with MS than those in the normal controls(P0.05).FBG had remarkably positive correlation with UFA/TFA,PUFA/TFA and PUFA/SFA(r=0.229,0.204,0.230,P

Objective To evaluate and compare two definitions for metabolic syndrome(MS)issued by International Diabetes Federation(IDF)and by Chinese Medical Association Diabetes Branch(CDS).Methods An epidemic survey and physical examination were conducted among 481 subjects randomly selected from 3 354 subjects(above 40 years old)by cluster sampling.Results The prevalence rate of MS by IDF or by CDS definition were 40.96% and 38.05%,respectively.Kappa value was 0.51,P0.01).Metabolic disorder ratio for above 3 items by IDF was higher than that of CDS criterion.Conclusion The IDF diagnostic criterion for MS and CDS are in good accordance and applicability.The MS diagnostic criterion of IDF is better at diagnosing centricity obesity than that of CDS.

Anterior communicating artery (AcomA) aneurysm is one of the most common intracranial aneurysms.Interventional treatment of wide-neck AcomA aneurysms remains challenging.With the emergence of several intracranial stents and the innovation and development of a variety of stent technologies,stentassisted coiling (SAC) embolization has gradually become one of the preferable techniques for the treatment of wide-neck AcomA aneurysms.This article reviews several SAC embolization techniques of AcomA aneurysms.
