[Objective]To investigate the technique and significance of arthroscopic anterior cruciate ligament(ACL) reconstruction with the remaining bundle and ruptured fiber.[Method]In 47 cases of ACL rupture verified with arthroscopy,there were 15 cases of partial disruption,26 cases of complete disruption,and 6 cases of ligament flabby.ACLs were reconstructed with single bundle of autogenous quadrupled hamstring tendons under arthroscopy without remove of the remaining bundle or remnants of ACL.The femur tunnel was fixed by the RigidFix system,and the Intrafix system was used to fix the tibia tunnel.[Result]All of 47 cases were followed up for an average of 19 months(ranged from 12 to 24 months).The stabilization was strengthened after operation.Lysholm knee function score increased by 26.3 scores,from average 68.6 scores of preoperation to average 94.9 scores after operation.Lachman test was negative in 43 cases,weakly positive in 3 cases and positive in 1 case.According to Insall knee therapeutic effect evaluation criterion,38 cases achieved excellent results and 9 cases achieved good results.[Conclusion]Arthroscopic reconstruction of ACL with the remaining bundle preserving technique could facilitate revasculization and reinnervation of the reconstructed ligament and maintain stability of knee joint.

Objective The questionaires of the ONFH aegers who were hospitalized in Kanggu hospital,during 2005-2008 ,were collect-ed to evaluate the therapeutic effects of acupotomy by proper statistical methods. Methods Four indexes according to the criteria of Therapeutic effect of adult ONFH recovery and reconstruction (ZHAO Dewei, 1996) were measured to evaluate the effect of the treatment. Results Monofac-torial analysis showed that the treatrnent was effective,but some phenomena could not be correctly explined in specialized field. This problem was re-solved appropriately by structural equation model(SEM). Conclusion By the method of SEM, the confounding factors could be better controlled and the evaluation was more reliable.

Objective To explore the inhibition effect of interleukin-10(IL-10)on pneumonic anaphylacticitis in mice with asthma and its effects on the level of serum IgE.Methods Thirty BALB/c male mice whose weight were(20?2)g were randomly divided into 3 groups:normal group(n=10),asthma model group(n=10)and IL-10 treatment group(n=10).Asthma model group and IL-10 group were sensitized with 1 g?L-1 ovalbumin,then asthma model was made with inhallating 10 g?L-1 VOA 20 mL.The normal group was not administered anything as a negative group.Before inhallating with 10 g?L-1 VOA,asthma model group was administered inhalation with 9 g?L-1 saline 0.1 mL,and IL-10 treatment group was administered inhalation with 0.1 mL IL-10 whose concentration was 0.2 ?g?L-1.The level of IgE was measured by ELISA reagent box,eviscerated lungs after collecting blood and then made them into pathological slices.Results There was an obvious distinction in the mice pathological change of lungs and bronchus between asthma model group and other groups,but no significant difference between IL-10 treatment group and normal group.There was no obvious infiltration of inflammatory cells in the airways of IL-10 treatment group and normal group.However,there were a great number of inflammatory cells in the interstitial and peribronchovascular regions of asthma model group.The levels of serum IgE were(5.219?0.427)?g?L-1,(6.633?0.145)?g?L-1 and(5.503?0.566)?g?L-1 in normal group,asthma model group and IL-10 treatment group,respectively.The level of serum IgE in asthma model group increased obviously compared with normal group and IL-10 treatment group,with significant differences(Pa0.05).Conclusions Inhalation of IL-10 can optimally control the pneumonic anaphylacticitis,improve the situation of airway inflammation in mice asthmatic model and reduce the IgE serum level.

Aim To study the effect of simvastatin on ventricular remodeling in rats after myocardial infarction,and the association between this effect and phosphorylating extracellular signal-regulated kinase1/2(p-ERK1/2).Methods Myocardial infarction(MI)rat models were successfully induced by ligation of anterior descending coronary artery.The treated rats were randomly divided into 4 groups(n=8~10):MI only group,MI plus 20 mg Sim group(20 mg?kg-1?d-1),MI plus 40 mg Sim group(40 mg?kg-1?d-1),and sham-operated group.After 4 weeks,the rats were checked by echocardiography including LVEDd,LVPWd,LVEF,FS,SV and CO.Myocardial p-ERK1/2 was also examined by immunohistochemistry and Western blot.Results Compared with sham-operated group,LVEDd,LVPWd in other groups were significantly increased(P

Objective To study compatibility stability of Danshen injection combined with dopamine injection in 5% glucose injection. Methods The relative contents of tanshinol sodium, protocatechuic aldehyde, rosmarinic acid,salvianolic acid B in Danshen injection and Dopamine hydrochloride in dopamine injection were determined by HPLC in 6h after the compatibility in the above infusion at 5 ℃,25℃,35 ℃ under dark and light,and the changes in pH value,appearance and insoluble particles were also observed.ResuIts There were no significant changes in appearance and pH value at 5℃,25℃,35 ℃ under dark,insoluble particles were in line with Chinese Pharmacopoeia,and the relative content of tanshinol sodium, protocatechuic aldehyde, rosmarinic acid,salvianolic acid B and Dopamine hydrochloride were above 99%(compared with 0h) in 6h.In the light conditions,as the temperature raised,the extension of storage time,the relative content of Dopamine hydrochloride was not significantly decreased,but the content of tanshinol sodium, protocatechuic aldehyde, rosmarinic acid and salvianolic acid B had declined,while pH value also had a certain degree of reduction,the insoluble particles had no obvious change.ConcIusion The mixture of Danshen injection and dopamine injection in 5%glucose injection is stable under dark conditions in 6h, illumination and temperature maybe the main factor affecting the stability of Danshen injection combined with dopamine injection.

Objective To study the relationship between the imaging patterns of microvasculature change and histological diagnosis.MethodsOne hundred and thirty-seven patients with esophageal mucosa roughness,erosion,plaque,abnormal color and indentation in conventional endoscopy and thirty healthy volunteers were enrolled in this study.The magnifying endoscopy images were graded as four patterns by intraepithelial papillary capillary loop(IPCL) changes by NBI .The biopsies underwent pathologic evaluation.The imaging patterns of endoscopy and histological diagnosis were compared and statistically analyzed.Results137 patients were diagnosed by narrow-band imaging system with magnifying endoscopy combined miniprobe sonography.Among these patients,27 cases were pathologically diagnosed as squamous cancer including 15 cases of early esophageal cancer,21 cases were high grade intraepithelial neoplasia,23 cases were low grade intraepithelial neoplasia,66 cases were chronic inflammation.100% esophageal carcinoma and high grade intraepithelial neoplasia were Ⅳ,Ⅲ type IPCL,56.52% low grade intraepithelial neoplasia was Ⅲ type IPCL,43.48% wasⅡtype IPCL,90.91% esophagitis wasⅡtype IPCL.100% esophageal normal mucosa wasⅠtype IPCL.The difference was significant among esophageal carcinoma,high grade intraepithelial neoplasia and esophagitis,esophageal normal mucosa (P＜0.05).ConclusionsThe imaging patterns of microvasculature change under NBI magnifying endoscopy were crucial in the diagnosis and identification of benign and malignant of esophageal disease.

The effect of initial substrate concentration on the growth,metabolic activities of Photosynthetic bacteria (PSB) in the process of hydrogen production is studied.The empirical relation of the initial substrate concentration to the specific growth rate,specific substrate consumption rate and specific hydrogen production rate of PSB are developed based on the modified Monod model.It is found that the results given by the model are well agreed with the experimental data in growth phase and stationary phase of PSB.Meanwhile,the optimal substrate concentration in the process of growth,metabolism and hydrogen production is 50 mmol/L.Furthermore,when the initial substrate concentration deviates 50 mmol/L,the activation of PSB is limited or inhibited,and the inhibiting effect is more prominent than the limiting effect.In addition,it is demonstrated that initial substrate concentration has little effect on the specific substrate consumption rate.
