Objective To evaluate the value of creatine kinase MB(CK-MB) and cardiac troponin I(cTnI)to earlier diagnosis on myocardial injury in newborn infants with asphyxial.Methods Dynamic variation of serum CK-MB and cTnI levels were measured at birth 1,5 and 10 days,respectively,in 40 asphyxia newborn infants and 20 control neonates.Results Serum CK-MB and cTnI levels of asphyxia neonates were significantly higher than those in control group(P0.05).Conclusion The determination of CK-MB and cTnI levels can help the prediction of myocardial injury after asphyxia.

Objective To evaluate the value of ultrasound (US) in assessment knee joint inflammation in patients with juvenile rheumatoid arthritis(JRA).Methods US scans of the knees obtained in 30 children at clinically active stage; JRA was compared with those obtained in 30 healthy children and 10 JRA patients in clinical remission.Results Changes in synovial membrane thickness and presence of fluid in suprapatellar bursa showed statistically significant differences between JRA patients with active disease and the other subjects.Alterations in contour of the articular cartilage were demonstrated in 10 knees of patients with JRA.Conclusion US is a simple sensitive and reliable methods for the assessment and monitoring of knee joint involvement in JRA.

OBJECTIVETo explore the clinical effects of PLIF surgery for elderly patients with lumbar degenerative disease.

METHODSFrom March 2010 to May 2013, 28 patients with lumbar degenerative disease, aged more than 80 years were treated with PLIF surgery. There were 10 males and 18 females, aged from 80 to 93 years old with an average of (85.44±3.66) years. Course of disease was from 3 to 20 years. The operation time, intra-operative blood loss, operation complications were recorded and JOA scores and Macnab criteria were used to evaluate the clinical outcomes.

RESULTSAll patients were followed up from 12 to 40 months with an average of 26.5 months. The average operation time was (150.00±26.42) min and the average intra-operative blood loss was (373.33±99.88) ml. The pre-operative JOA score was 12.30±2.43, and the corresponding postoperative JOA score at the final follow-up was 24.81±2.09 which was much higher than the preoperative one (P<0.01). According to the modified Macnab criteria to evaluate at the final follow-up, 16 patients got an excellent result, 10 good, 2 fair. In the weeks postoperatively, injuries of nerve root happened in 3 cases, superficial wound infection with delayed healing in 3 cases, and tear of the dural sac accompanied with cerebrospinal fluid leakage in 1 case. After long term follow-up, adjacent segment degeneration and the corresponding spinal canal stenosis occurred in 1 case at 34 months after operation. All cases got successful fusion without any displacement of internal fixation and pseudoarthrosis formation.

CONCLUSIONWith proper cases, fully preoperative preparation, perfect intra-operative manipulation and active treatment after operation, even advanced ages older than 80 years with lumbar degenerative disease could get satisfactory outcomes after PLIF surgery.

OBJECTIVETo observe clinical efficacy in treating cutaneous deficiency of traumatic shank amputation stump with full-thickness skin graft combined with vacuum sealing drainage.

METHODSFrom September 2009 to December 2012, 15 patients with cutaneous deficiency of traumatic shank amputation stump were treated with full-thickness skin graft combined with vacuum sealing drainage. Among patients, there were 11 males and 4 females with an average age of 41.5 (ranged from 25 to 62) years old. Ten cases were caused by traffic accident and 5 cases were caused by heavy object, 9 cases on left and 6 cases on right. Six patients with smashed wound were treated with debridement and amputation, combined with vacuum aspiration in-emergency; 9 patients caused by infection and necrosis were treated with debridement and amputation, combined with vacuum aspiration, and full-thickness skin graft were performed at stage II. The skin defect area of residual limbs ranged from 40 cm x 20 cm to 25 cm x 15 cm.

RESULTSAll patients were followed up from 3 months to 1 year. Full-thickness skin graft of residual limbs were survived,and obtained satisfactory walking function with prosthetic. Residual skin increased thicken, wearproof without rupture and pain.

CONCLUSIONFull-thickness skin graft combined with vacuum sealing drainage in treating cutaneous deficiency of traumatic shank amputation stump could reserve the length of residual limbs, increase survival rate of skin graft with less scar of survival skin, get good wearability and it is conducive to prosthetic wear. It is a simple and easy treatment method.

Objective To investigate the effects of integrin β1 gene expression inhibited by short hairpin RNA (shRNA) on invasion of pancreatic carcinoma PANC1 cells in vitro,and investigate the mechanism.Methods The eukaryotic expression plasmid of shRNA targeting integrin β1 gene ( integrin β1 shRNA) and control eukaryotic expression plasmid shRNA (c-shRNA) was constructed and was transfected into PANC1 cells.The cells without plasmid transfection were used as control.The expressions of integrinβ1,MMP 2,MMP 9 mRNA and protein were detected by real-time PCR and Western blotting.The invasive ability of PANC1 cells was observed with Transwell cell culture chamber.Results Integrinβ1 mRNA expressions in integrinβ1 shRNA group,c-shRNA group and control group were 0.0029 ± 0.0004,0.0131 ± 0.0009,0.0138 ± 0.0005 ; the expressions of integrinβ1 protein were 0.0159 ± 0.0062,0.3215 ± 0.0126,0.3107 ±0.0094; the inhibitory rate of integrinβ1 mRNA and protein expression in integrinβ1 shRNA group was (78.6 ±7.2 ) ％ and (92.9 ± 3.2) ％ ( P ＜ 0.01 ).But there was no difference between the c-shRNA group and control group (P =0.2999).Number of penetrating cells in integrinβ1 shRNA group decreased from 52 ±5 to 21 ±4( P ＜ 0.01 ) ; the expression of MMP 2 and MMP 9 mRNA decreased from 0.592 ± 0.073,0.847 ± 0.069 to 0.102 ± 0.034,0.273 ± 0.071 ; the expression of M MP2 and MMP 9 protein decreased from 0.225 ± 0.046,0.416 ±0.081 to 0.059 ±0.013,0.106 ±0.022(P ＜0.05).Conclusions Recombinant integrinβ1 shRNA expression plasmid can effectively inhibit the expression of integrinβ1 gene and suppress the invasion of PANC1 cells in vitro by down-regulating MMP 2 and MMP 9 gene expression.

17 strains of bacterium that produced a large amount of ?-PGA when it was grown aerobically in a culture medium containing ammonium salt and sugar as sources of nitrogen and carbon respectively,were isolated from bean products.With the following identifications of colony morphology,physiological and biochemistry experiments,and genetics,the strain PGA-O-7 was classified as a Bacillus subtilis.The PGA production 2.8 (mg/mL) was obtained when it was grown in a medium containing 3% ammonium sulfate and 4% glucose at 30℃ for 72h with sharking.
