The human canstatin cDNA was amplified by RT-PCR and then directionally cloned into pU? expression vector. The recombinant pU?-Can vector was connected with the screening marker (bar box), to construct a eukaryotic expression vector called pU?-Can-Bar. This expression vector was introduced into the D.salina by glass beads method. The screening culture of transformants of D.salina was performed in solid media containing 5 ?g/ml PPT, and the analyses of transformants were carried out through PCR and Southern blot. PCR results revealed that specific 700 bp products were detected in the different transformants of D.salina but not in negative control. Southern blot analysis further demonstrated that human canstatin gene was integrated into the D.salina genome. Moreover, the results of genetic stability analyses of transformants demonstrated that canstatin gene was stably inherited in the D.salina transformants. The successful preparation of the D.salina transformants will provide the experimentation evidence for producing canstatin protein cosmically by using the D.salina bioreactor and give a better prophase work basis for clinic application of canstatin protein early.

Objective To explore the outcome of modified bladder neck reconstruction in treating the urinary incontinence due to the sphincter dysfunction.Methods Between January 2010 and December 2014,a total of 23 patients,including 16 male and 7 female cases,with incontinence due to sphincter dysfunction had undergone a procedure of modified bladder neck reconstruction.The mean age was 36 years (range 17-61 years).Etiology of incontinence was secondary to pelvic fracture and urethral rupture procedure in 19 patients and other failure procedures in 4 cases.The mean duration of incontinence was 2 years (range 1-5 years).Urodynamic examination was performed in all patients and the mean maximum urethral pressure was 34 cmH2O (range 21-43 cmH2O).The modified bladder neck reconstruction was performed in 23 patients.Under the general anesthesia and vertical bladder incision,triangular mucosal strips,from the bladder neck to ureteral office,were denuded and leaving the central urethral plate,which was 2.0-2.5 cm in width.In order to form a neourethra and bladder neck,the multilayer triangular muscles were sutured interruptedly over a 14-16 F catheter using 2-0 or 3-0 polyglactin.And the anterior wall of the bladder was then closed over the new bladder neck using continuous sutured.Results The 23 patients were followed up for 6 months to 3 years,mean 1.4 years.Continence achieved in 5 patients.Of them,2 patients had difficulty in voiding but corrected by indwelling the catheter for another 2 weeks.Social continence was achieved in 7 patients.Incontinence status was improved in 7 cases and failed in 2 cases.Urodynamic examination was performed in 4 patients and the mean maximum urethral pressure was 64 cmH2O (range 52-72 cmH2O).Conclusions Our study suggested that the modified bladder neck reconstruction was a good procedure for the treatment of urinary incontinence due to sphincter dysfunction,particularly for the incontinence secondary to the traumatic urethral stricture or other operation.

BACKGROUND: Unrepaired bucket handle meniscus tear(BHMT)could result in partial or total meniscectomy,which aggravates the degeneration of knee joint.The long-term,large sample studies regarding the success rate of BHMT repair are few.OBJECTIVE: To retrospectively analyze the clinical result of arthroscopic BHMT repair and explore the preoperative diagnosis,repair technique,treatment effect evaluation and influential factors,so as to investigate ideal repair method of large meniscus tear injury.METHODS: From May 2002 to November 2005,90 patients with repairable BHMT were treated in Sports Medical Center of Beijing Jishuitan Hospital.Of the 90 patients,61(63 menisci)were followed up for over 2 years with an average duration of 38months(24-66 months).The indications of BHMT repair include red-red area and red-white area injuries,reductable,meniscus with no compound tear or degeneration.RESULTS AND CONCLUSION: Of the 61 followed up patients,53 menisci in 51 patients(84%)were assessed by second-look arthroscopy; 53 of 61 patients(87%)were asymptomatic,4(6%)patients were partial asymptomatic and 4(6%)had recurrent locking showing failure.Second-look arthroscopic examination showed that 44 menisci(83%)were healed completely,5(9%)partially healed,and 4(7%)not healed.The total failure rate was 8%(5/63),and success rate was 92%,including complete healed,partial healed,asymptomatic and partial asymptomatic patients.For large bucket-handle meniscus tears involving red-red and red-white zones,reliable arthroscopic hybrid suture technique,provides stable suture strength along the whole length of injured region and consequently achieves improved clinical outcomes in combination with anterior cruciate ligament.

Objective To detect the methylation status of p16 gene promoter in CD4~+ T cells of patients with systemic lupus erythematosus(SEE),and its significance in the pathogenesis of SLE.Methods The pl 6 gene promoter methylation in peripheral CD4~+ T cells was detected with the Taqman probe-based realtime PCR(Methylight)technology in 28 patients with SLE and 20 healthy human controls.Results The methylation rate of p16 gene promoter in peripheral CD4~+ T cells was higher in patients with SLE than that in the controls(35.7%VS 10%,x~2=4.11,P<0.05).There was no correlation between SLE disease activity index (SLEDAI)and the normalized index of methylation(NIM)of p16 gene promoter(r_s=-0.29,P>0.05).Conclusion The methylation status of p16 gene promoter is aberrant in CD4~+ T,:ells of SLE patients,suggesting that the hypermethylation of p16 gene plays a certain role in the pathogenesis of SLE.

To observe the clinical effect of Yisui decoction plus western medicine in treating multiple system atrophy patients, totally 65 patients from China-Japan Friendship hospital during 2008-2012 with complete clinical data and received consecutive traditional Chinese medicine and western medicine treatment for more than 3 months were observed changes of traditional Chinese medicine symptom score, part 1 of unified multiple system atrophy rating scale, orthostatic hypotension before treatment and after 3 months treatment. After 3 months treatment, total effective rate of traditional Chinese medicine symptom was 70.8%. Compared with before treatment, score of part 1 of unified multiple system atrophy rating scale was obviously reduced after 3 month treatment (P < 0.001). Ex- cept swallow function without significant improvement, the remaining projects of unified multiple system atrophy rating scale were im- proved obviously (P < 0.05), of which the most obvious differences were orthostatic symptoms, falls and intestinal function (P < 0.001). Orthostatic hypotension after 1 month treatment and 3 month treatment was obviously better than before treatment (P < 0.001). There was no significant difference in orthostatic hypotension between 1 month treatment and 3 month treatment. The research results show that Yisui decoction plus western medicine has a certain effect on improving clinical symptoms of multiple system atrophy patients, especially has a significant effect on orthostatic hypotension, and can maintain a stable clinical effect in a certain period of time.
