Objective To analyze the incidence, clinical feature and late complications, and treatment for diabetes ketoacidosis (DKA) in children with type 1 diabetes mellitus.Methods Ninty children with type 1 diabetes mellitus within 10 years were retrospectively reviewed.The onset situation,clinical feature and long-term complication,and treatment of DKA were analized.Results High morbidity was found in 10 to 16 years old children.DKA was often caused by infection; late complications of diabetes mellitus was resulted from interrupted injection of insulin.Conclusions Emergency treatment for DKA may involve the injection of small dose insulin,correction of the disorder of water and electrolysis and regulation of acid-base.The education of patients and parents about diabetes mellitus and long-term injection of insulin are of importance in preventing the complications.

Objective To study the present situation of legionella pneumophila(Lp) infection of low respiratory tract infection in children less than 5 years old.Methods Three hundred hospitalized patients with the diagnosis of low respiratory tract infection were enrolled in the study,191 males,109 females,aged 27 d to 5 years old,course from 1 d to 6 months.Serum antibody(IgM,IgG) of Lp serogroup 1-7 was detected by enzyme-linked immunosorbent assay(ELISA).Results In the patients,17 cases were positive,and the positive rate was 5.67%.Of the 17 children,the males(n=11) and females(n=6) did not significantly influence the positive rate(5.76% vs 5.50%).Four of them were between 27 days and 1 year old;7 were 1 to 3 years old,6 were 3 to 5 years old.The positive rates were significantly different among the 3 groups(2.53% vs 7.37% vs 12.77%) and tendentially increased following the increase of age(?2=7.8164 P

Objective To evaluate the usage of renoportal anastomosis in the liver transplanta- tion.Method The successful experience about renoportal anastomosis for portal vein reconstruction in liver transplantation was reported,and related literature reviewed.Results Including our case,there have been 13 cases of liver transplantation using renoportal anastomosis for portal vein reconstruction. Among these patients,8 cases were complicated with diffuse portal vein thrombosis,and 10 cases had a splenorenal shunt(spontaneous shunt in 3 and surgical shunt in 7).Complications related to portal vein hypertension occurred in 3 cases(transient ascites in 2 cases and severe digestive bleeding in 1 case)after liver transplantation.There were 3 deaths which were not related to renoportal anastomo- sis.Conclusion Renoportal anastomosis is a safe and feasible technique in liver transplantation for the patients with diffuse portal vein thrombosis or with splenorenal shunt(spontaneous or surgical shunt).

Objective To evaluated the expression of vascular endothelial growth factor -C(VEGF-C) in children with neurob-lastomaor willms' tumors. Methods The specimens from 33 cases with neuroblastoma and 30 cases with willms' tumors were detected by immunohistochemical staining method. Results In thirty - three cases of neuroblastoma, stage III VEGF - C positive rate were 37.5% (3/8),stage IV were 32% (8/25);favourable histological(FH) were 45%(9/20),unfavourable favourable histological(UFH) were 30.8%(4/13).Cases with distant meta stasis were 32% (8/25),and cases with lymph node involvement were 66.7%(4/6). In 30 cases with willms' tumors,stage I + II were 26.7% (4/15),while stage III + IV were 40% (6/15), FH were 27.3% (6/22), while UFH were 25% (2/8). Cases with distant metastasis were 33.3% (4/12),and cases with lymph node involvement were 60% (3/5). VEGF-C positive expression rate was significantly higher in tumors from children with lymph node metastasis than those without. Conclusion The study shows that expression of VEGF -C is related to lymph node metastasis.

Arachidonic acid is an essential fatty acid in human nutrition and a biogenetic precursor of the biologically active prostaglandins and leukotrienes. ?~5 desaturase catalyzes the ?~5 dehydrogenation of di-homo-?-linolenic acid to form arachidonic acid in biosynthetic pathway of arachidonic acid. Using real time PCR technology,the transcriptional expression levels of gene encoding ?5 desaturase in three Mortierella alpina strains M10,M6 and M23,and in different growth phase of high arachidonic acid yielding strain M6,were determined. Results showed that there was a distinct corelationship between mRNA transcript level of ?~5 desaturase gene and biosynthesis of arachidonic acid. Results indicated that ?~5 desaturase plays an important role in arachidonic acid biosynthesis.

OBJECTIVEThis study was to test the feasibility of permanent maxillary tooth removal using articaine without a second palatal injection.

METHODSOf 104 patients, 38 patients had bilateral extraction and 66 patients had unilateral extraction of maxillary tooth. In the test group, 1.7 mL articaine with 1:100000 epinephrine was injected into the buccal vestibule of the tooth and the tooth were extracted after 5 minutes. In the control group, the patients were subjected to both palatal injection with 2% lidocaine hydrochloride and buccal injection with articaine. All patients completed visual analog scales (VAS) after extraction.

RESULTSThe achievement ratio of permanent maxillary tooth anesthesia of test group was 96.2%. The achievement ratio of permanent maxillary tooth anesthesia of control group was 97.1%. There was no statistical significance between achievement ratio of test group and control group(P > 0.05).

CONCLUSIONPermanent maxillary tooth removal without palatal injection is possible by articaine injection to the buccal vestibule of the tooth.
