Objective To discuss the repair methods for the cartilage defects of the knee joint. Methods The cylindrical osteochondral grafts were harvested from the non-weight-bearing area of the knee joint and then transplanted to the cartilage defects in 6 patients with cartilage defects of the knee joint. Results The clinical symptoms of all the patients followed up for 2-24 months disappeared and the joint mobility recovered to normal. A follow-up MRI showed consistent cartilage coverage and the excellent position of the cylindrical osteochondral grafts. Conclusions The osteochondral autograft is a practical surgical method because it is characterized by less trauma, simple performance and good maintenance of the curvature of the articular surface.

Objective To investigate the effect of tunor necrosis factor alpha (TNF-α) antagonist treatment and traditional disease-modifying antirheumatic drugs treatment on the quality of life of male patients with ankylosing spondylitis (AS).Methods In 42 patients with AS open-label study,patients were grouped after consent,and divided into the TNF-α antagonist treatment group and the non-TNF-α antagonist treatment group.All patients were treated for 4 months.The clinical and laboratory indexes and quality of life changes were analyzed before and after the treatment.T test,Pearson's correlation analysis were used for statistical analysis with software version 13.0.Results There were no significant differences in age,disease course,disease activity and the quality of life between the two groups before treatment.Disease activity and the quality of life of the two groups after treatment were improved compared with that of before treatment.After treatment,the Bath ankylosing spondylitis disease activity index (BASDAI) score [(1.9±1.6) scores,(3.0±1.3) scores,t=-2.429,P=0.020],erythrocyte sedimentation rate (ESR) [(9±6) mm/1 h,(18±17) mm/1 h,t=-2.286,P=0.031] and C reactive protein(CRP) levels [(18±21) mg/L,(62±85) mg/L,t=-2.258,P=0.035] of the TNF-α antagonists treatment group decreased significantly than those non-TNF-α antagonist treatment group,while the hemoglobin (Hb) levels [(143±15) g/L,(138±18) g/L,t=2.545,P=0.015] were significantly increased in TNF-α antagonist treatment group.The improvement extent of quality of life was more evident in TNF-α antagonists treatment group,such as,the average score [(72± 15) scores,(55±19) scores,t =3.254,P=0.002].The average degree of improvement in quality of life and BASDAI score,Bath ankylosing spondylitis functional index (BASFI) score were negatively related to the improvement in the TNF-α treatment group (r=-0.497,P=0.018; r=-0.558,P=0.007).Conclusion TNF-α antagonist treatment can not only improve the AS disease activity,but can also improve the quality of sexual life of male patients,which may direct affect on male reproductive system.

The myocardial nutrition after myocardial revascu-larization was studied in 14 rabbits with the aid of Nd-YAG laser, before Ligation of the anterior descending branch of the left coronary artery (only ligated LAD in 4 rabbit), the rabbits were seperatively Killed 3 or 5 weekafter operating. Myocardial samples were abtained in the parti of 0 - 2,2 - 4,4 - 6mm from laser hole. Sample numbers were 30 in myocardial revascularization group (MRG); 20 in myocardial Infarction group(MIG); 20 in normal group (NG). Amount of ATP and CP in myocar-dia were determined with luciferase. Resalts.ATP and CP near laser holes were normal 3 week late. This far from laser holes was lower than that of normal myocardia 5 week late. Recover of CP amount was slower than that of ATP amount. Inclusion, myocardial revascularization can play role in myocardial nutrition.

Objective] Discussion on academic ideas and clinical experience of professor Dong in treatment of varicocele sterility.[Methods]From academic theory, etiology and pathogenesis, therapeutic principle treatment aspects in professor Dong diagnosis and treatment of varicocele sterility certificate academic view and clinical experience, to summarize its characteristic diagnostic medicine.[Results] Professor Dong considers varicocele infertility disease in liver and kidney, etiology and pathogenesis is kidney, liver, blood stasis, based on the kidney essence deficiency, diseases with ease, and blood stasis resistance as the standard, the causal, with kidney and liver qi activating blood method in the treatment of varicocele thought and method has achieved good clinical therapeutic effect. [Conclusion]The clinical experience of professor Dong in treatment of varicocele syndrome is effective, has the value of popularization and application.

Objective To identify the clinical features and risk factors of rheumatoid arthritis-associated interstitial lung disease (RA-ILD).Methods The clinical and laboratory data of 595 patients with RA hospitalized in Chaoyang Hospital.550 cases of patients were performed pulmonary high-resolution CT examination.Risk factors were analyzed with logystic regression analysis.Results ① There were 237 (39.8％)patients with RA-ILD.13.5％ of RA-ILD occurred before the dia-gnosis of RA,69.7％ of RA-ILD occurred within ten years after the diagnosis of RA,16.8％ of RA-ILD occurred more than ten years after the diagnosis of RA.② The most common manifestations of HRCT were reticular opacity (57.8％),pleural thickening (57％),ground-glass opacity (53.2％),followed by septal thicke-ning,nodules,bullae,cellular-like changes and bronchiectasis.③ Pleural disease,bronchiectasis,pulmonary hypertension in RA patients were associated with RA-ILD.④ Compared with the RA-N-ILD patients,RA-ILD patients had a higher proportion of male patients,higher rate of smoking,older mean age at onset,shorter duration,more swollen joints higher levels of lactate dehydrogenase,globulin,erythrocyte sedimentation,C-reactive protein and rheumatoid factor,the difference was statistically significant (P＜0.05).The forced vital capacity,forced expiratory volume in one second,carbon monoxide diffusion rate was lower,the difference was statistically significant (P＜0.05).Logistic regression analysis showed that age,smoking,elevated lactate dehydrogenase,RF-positive rate were relevant factors of RA-ILD.Conclusion ILD is common in RA,and most of it occurrs within ten years after the diagnosis of RA,and often coexists with other lung disease.Age,smoking,elevated lactate dehydrogenase,RF-positive rate

BACKGROUND:Whether a long-term use of acid-suppressive medication for over 3 years can increase the risk of fractures, remains controversial.
OBJECTIVE:To systematical y review the effect of acid-suppressive medication on fracture risk.
METHODS:Clinical trials about the relationship of acid-suppressive medication use and risk of osteoporosis-related fractures were searched in MEDLINE, Cochrane Library, EMbase, and CNKI database. We also manual y searched some published and unpublished references. Study selection and assessment, data col ection and analyses were undertaken by two reviewers independently. The Cochrane Col aboration’s RevMan 5.0 software was used for data analyses.
RESULTS AND CONCLUSION:After a comprehensive search, 11 original clinical trials were included in this meta-analysis, including 3 nested case-control studies, 5 case-control studies, and 3 cohort studies. Patients with fractures were more likely than controls to have previously received supply of proton pump inhibitors [odds ratio (OR)=1.29, 95%confidence interval (CI) (1.18-1.41), P<0.001]. The meta-analysis did not find a significant difference in the patients who received H2 receptor antagonists [OR=1.10, 95%CI (0.99-1.23), P=0.34]. A long-term use of proton pump inhibitors is associated with an increased risk of fracture in elderly persons already at a risk for osteoporosis.
