Objective To explore a kind of modified peritoneal dialysis (PD) adapt for acute renal failure (ARF) in children. Methods After punctured many pinholes in tail end and sterilized by ethylene oxide the ID 2. 5 tracheal tube and urinary catheter were used as PD - catheter for children. The tracheal tube or urinary catheter was placed in abdomen with Seldinger's techniques Then the PD was carried out in the way that dialysis solution passing in and out of abdomen in two different pipelines Results The edema, circulation and respiration of the 21 children with ARF were improved after PD in this way and the urine quantity increased too, although 5 of them died of D1C and MOSF. No peritonitis or leakage of PD solution was taken place. The Scr.BUN,UA,K + ,CO2- CP of the chidren were decreased from(424? 133)?mol/L,(41.5? 12 6) mmol/L, (764 ? 187) ?mol/L,(6 7 ?2. 1) mmol/L, (14 5 ? 3.7) mmol/L before PD to( 166?37) ?mot/L,(8.9?3 1) mmol/L,(350?74) ?mol/L,3.7?0 4 mmol/L,(23.0? 1. 8) ?mol/L.Conclusion Tracheal tube or urinary catheter may be used as PD- catheter for ARF in children.

OBJECTIVE To investigate the distribution and the resistance of pathogens from the children with VAP in PICU,and to analyze the reasons of antibiotics resistance of the pathogens.METHODS The sputum obtained from the children with final diagnosis of VAP in PICU was cultured and identified from Jan 2005 to Dec 2006.The resistance of the bacteria identified to antibiotics used frequently was determined by Kirby-Bauer method.RESULTS A total of 187 strains were isolated from sputum specimens,of which Gram-negative bacilli and Gram-positive cocci accounted for 76.5% and 23.5%,respectively.Acinetobacter baumannii(17.7%),Escherichia coli(16.0%),Pseudomonas aeruginosa(15.0%) and Klebsiella pneumoniae(13.9%) were the most frequently isolates of Gram-negative bacilli.Their resistant rates to ?-lactam antibiotics were high,especially the ESBLs-producing strains in E.coli and K.pneumoniae.The Staphylococcus epidermidis(5.9%),Staphylococcus aureus(4.8%) and Enterococcus faecalis(4.3%) were the most common strains of Gram-positive cocci.No vancomycin-resistanct strains were found,but resistance rates to ?-lactam antibiotics and other antibiotics were high in S.epidermidis and S.aureus.CONCLUSIONS The main strains cultured from the sputum specimens of children with VAP in PICU are Gram-negative bacilli with high resistance rates to antibiotics,especially the ESBLs producing bacilli to ?-lactam antibiotics.Staphylococcus are the main Gram-positive cocci.

Objective To evaluate the value of reconstruction of three-dimentional CT in development dislocation of hip(DDH)in children.Methods Twelve cases of DDH concluded 4 bilateral and 8 unilateral cases.To sum up,16 sick hips were operated and 8 normal hips were also obtained by three-dimensional CT(Hip speed Fi/x,GE Co).Results 3D reconstruction were used to show femoral head,(acetabulum) and relationship of acetabulum and femoral head respectively.The difference between FNA measurement of sick hips and those of normal hips were significant(P

Objective To investigate the clinical epidemiologic features of transient synovitis(TS) of hip in children occurred in Shen-zhen district.Methods The medical files were reviewed and a standard questionnaire was filled according to the conditions of 705 cases such as pathogeny,clinical manifestation,therapy and prognosis.Results Transient synovitis occurred in a sporadic form all the year round.The peak age of patients with TS was 3-7 years old.The ratio of boys to girls was 2.9:1.About 19.3% patients were attacked an upper respiratory tract infection and 11.9% patients attributed the symptoms to trauma or severe activities before 1 week.A varying degree of painful limp and restriction of movement at the hip were found clinically.All of cases were cured by skin traction.The incidence of recurrence was 6.95%.Conclusions Male predominance is found in TS.It is characteristic of sporadic form in the 4 seasons and intently relation to an upper respiratory tract infection and trauma or severe activities.TS is recurrent and the prognosis is good by skin traction.

Objective To investigate the diagnostic value of double balloon endoscopy (DBE) in the elderly. Methods Clinical manifestations and endoscopic findings of 42 elderly patients (aged 60-80 years) and 73 young and middle-aged patients (aged 12-59 years) with small bowel lesions were obtained and compared. Factors influencing the diagnostic outcome of DBE in patients with small bowel bleeding were identified,and the optimal check time after the latest bleeding was determined.Results The procedures of 85.7％ (36/42) in the elderly and 79.5％(58/73) in young and middle aged were completed (P＞0.05).There was no significant difference in the procedure time between the two age groups.No severe complications were observed in the elderly group.The overall positive rate by double balloon enteroscopy examination were 71.4 ％ (30/42) and 63.0 ％ (46/73),respectively in the two groups (P＞ 0.05). Ulcer and tumor lesions were the most common findings,and diverticula and angiodysplasia were the second common findings. Longer duration of bleeding and higher number of bleeding episodes were found in the elderly with positive DBE findings than those with negative findings. Positive diagnostic rate was significantly higher when DBE was performed within 7 days than that after 7 days (90％ vs. 40％). Conclusions DBE is a safe,reliable diagnostic modality,especially in the elderly patients with small bowel bleeding in which ulcer and tumor lesions are the most common identifications.DBE is of greater benefit in patients with more bleeding episodes over a long period,and should be performed within 7 days after the last bleeding.

Objective To investigate the role of survivin and P53 in apoptosis of gastric adeno- carcinoma,as well as its relationship with the clinicopathologic features and the prognosis.Methods The gas- tric tissue microarrays were composed of those from 100 cases of gastric cancer and 30 controls.At these tissue microarrays,expressions of survivin and P53 were investigated immunohistochemically,and tumor cell apoptosis index was examined by TUNEL method.Of the 100 cases,47 cases were followed-up from 14 months to 13 years,in which the survival was analyzed.Results Two paraffin-embedded gastric carcinoma tissue micro- arrays were successfully constructed,including 114 and 116 tissue spots,respectively.Immunohistochemical analysis showed that survivin was expressed in 78 cases (78%).No expression of survivin was detected in control tissue (P0.05).In the 47 cases with followed-up data,univariant analysis revealed that the survival was correlated with invading of vessel and nerve,TNM stages,and expression of survivin.The histological grades and expression of P53 were not related to prognosis.However,Cox stepwise proportional hazards analysis showed that only TNM staging and survivin status retained significant independently in prospecting prognosis.Conclusions The expression of survivin was associated with the pathologic features,TNM stages and prognosis in gastric carcinoma,indicating that overex- pression of survivin may be a poor prognosis factor for gastric carcinoma.
