Objective To retrospectively evaluate the safety and efficacy of osteotomy for progressive congenital scoliosis combined with split spinal cord malformation (SSCM).Methods Data of 31 patients,who had undergone osteotomy for progressive congenital scoliosis combined with SSCM from May 2008 to May 2011 in our hospital,were retrospectively analyzed.Twenty-nine patients were followed up successfully,including 11 males and 18 females,aged from 6 to 26 years (average,13 years).Seven patients had tethered cord syndrome (TCS) with progressive neurologic deterioration.Hemivertebrae resection was performed in 7 patients,pedicle subtraction osteotomy (PSO) in 16,and vertebral column resection (VCR) in 6; posterior fusion surgery was performed in all patients after the correction was obtained.Results Twenty-nine patients were followed up for 8 to 24 months (average,18 months).The coronal Cobb angle ranged from 15° to 40°(average,24.4°±18.6°) immediately after operation,with an average correction rate of 63.3％.The coronal apical vertebral translation ranged from 0 to 50 mm (average,21.1±19.2 mm) immediately after operation,with an average correction rate of 59.5％.The coronal thoracic trunk shift ranged from 0 to 28 mm (average,5.5±10.5 mm) immediately after operation,with an average correction rate of 55.0％.There were significant differences between pre-and post-operative coronal Cobb angle,coronal apical vertebral translation and coronal thoracic trunk shift.There was no permanent neurological deterioration in all patients.Pedicle screw break occurred in 4 patients,without permanent neurological compromise.Among 7 patients with TCS,muscle strength was improved in 3 patients,and urination control was improved in 1 patient.Conclusion The osteotomy for congenital scoliosis combined with SSCM is a satisfactory method,which can effectively improve the spinal deformity without significant complications.For patients with TCS,this method also can improve the restoration of neurosurgical function.However,additional large multicenter studies are necessary to further assess the safety and efficacy.

Objective To investigate the influence of Helicobacter pylori(Hp) infection on gastric mucin MUC5AC and MUC6 expression in children.Methods Sixty-six cases with gastric biopsy specimens were obtained from 66 children undergone gastroscopy from Jan.2005 to Jun.2006 for episodic or continuous abdominal pain,nausea,vomiting,abdominal distension,retching and dyspepsia,and so on.Among these children,39 cases were male and 27 cases were female,owning a average age(8.8?3.0)years.These specimens were divided into 2 groups followed by the presence of Hp,which was detected by rapid urease tests and Hp-PCR.Gastric mucin MUC5AC and MUC6 mRNA were also measured by reverse transcription PCR(RT-PCR),and Hematoxylin and Eosin staining were used for pathology observation.Comparisons between every groups were performed using t test and ?2 test,and statistical significance was defined as P

Objective To analyze the cause of delayed hemorrhage after minimally invasive percu- taneous nephrolithotomy(MPCNL),and to summarize the experience in the interventional treatment of severe bleeding after MPCNL by superselective arteriolar embolization.Methods The clinical data of 3812 cases of MPCNL from June 1998 to July 2004 were reviewed.Of them,12 patients(11 men and 1 woman;mean age,45 years)who developed severe hemorrhage after MPCNL were identified.The cause of hemorrhage and the treatment results were analyzed.Results The rate of delayed hemorrhage after MPCNL was 0.31% (12/3812).The mean time to onset of severe bleeding was 10 d after MPCNL.Renal arteriography was per- formed in all 12 patients,showing 5 arteriovenous fistulas and 7 false aneurysms.Superselective arteriolar em- bolization for hemostasis was performed in all 12 cases.All these vascular abnormalities were successfully treated by superselective embolization.Follow-up showed that the hematuria disappeared and renal function recovered well.Conclusions Severe hemorrhage following MPCNL is a rare complication,the incidence of which is significantly lower than that of conventional PCNL.The cause is mainly the arteriolar injury of re- nal puncture passage.Superselective embolization provides effective control of bleeding and currently consti- tutes the treatment of choice based on our experience.

Objective To investigate the effect of angiotensin Ⅱ(Ang Ⅱ)on the expression of integrin-linked kinase(ILK)in rat glomerular mesangial cells.Methods SD rat glomerular mesangial cells were separated and cultured.They were treated with 10-7 mol/L Ang Ⅱ in various time-point(0,12,24,48,72 h),and then cultured rat glomerular mesangial cells were treated 48 h with Ang Ⅱ in various concentration(0,10-11,10-9,10-7,10-5 mol/L).Then total protein expression in rat glomerular mesangial cells stimulated by Ang Ⅱ at every time-point and every concentration-point was extracted.The expression of ILK protein was measured by Western blot.Results 1.Expression of ILK protein in rat glomerular cells stimulated by Ang Ⅱ in various time-point,or various concentration was significantly increased.In group of 10-7 mol/L Ang Ⅱstimulated cells,the protein semiquantity of ILK at 0,12,24,48,72 h respectively was 0.18?0.02,0.37?0.07,0.90?0.10,1.73?0.12,and 1.72?0.13(F=166.78 P

Objective To explore the relationship of proteinuria,immunopathogenesis and humoral immunity in children with Henoch-schonlein purpura nephritis(HSPN).Methods Serum IgG,IgA,IgM,C3 and C4 levels were detected with complete-automatic biochemistry analyzer in 47 children with HSPN and 18 heathy children,and the differences in the findings were compared among groups.The levels of IgG,IgA,IgM,C3 and C4 were compared among groups according to the count of proteinuria.The renal tissues were adopteded with immunity in the children with HSPN were taken for biospy examination,and the differences in immunopathalogy were compared among groups with immunof-luorescence assay.Results The IgG,IgA levels in children with HSPN were higher than those of heathy children,on the contrary,the IgM,C3 and C4 levels were lower than those of heathy children(Pa0.05),but the IgM level of the nephritic syndrome group were higher than that of other groups(Pa0.05).Conclusions There is severe disturbance of immunologic function in children with HSPN.There is no connections among serum IgG,IgA,IgM,C3 and C4 levels,proteinuria and renal immunopathlogy.

The stability of microbial flocculant (MBF) produced by Aspergillus sojae and its application to municipal thickened sludge dewatering were studied. The results showed that the MBF had high heat and acid-base endurance with high flocculating activity in a wide range of pH from 1.5 to 12. The MBF retained 96% of flocculating activity after 35 days preservation at 4℃, but in different pH the flocculating activity difference was very apparent after 35 days store at room temperature. The experimental results also demon- strated that the MBF was better than PAM and PAC in reducing specific resistance filtration. The optimal dose of MBF used for intensifying thickened sludge dewatering is 7%(volume fraction). And the more the volume of sludge is treated, the less the cost of MBF for unit volume sludge treatment.
