From April.1993 to Jan.1994,transcatheter maxillary arterial chemoem- bolization using Cisplatin microspheres(DDP-ms)in combination with PBF(DDP,BLM,5- Fu)had been used in 14 cases with regional relapsed nasopharngeal carcinoma and 3 cases of untreated locally advanced nasopharngeal carcinoma got positive response.The result showed 2 patients with Cr,13 PR,1MR and 1 NC advanced cases with PR.The total suc- cessful rate(CR+PR)was 88 24%(15/17),In addition,the main toxicity and coplicaton had been discussed.

Objective To evaluate the therapy and turnover of Kawasaki disease(KD)with glucose-6-phosphate dehydrogenase(G-6-PD)deficiency.Methods Six hundred and twenty-four patients with KD were selected including 32 patients who had G-6-PD defected.The same dose intravenous immunoglobulin(IVIG)was used in all 624 patients(2 g/kg),but used Dipyridamole in 32 patients had G-6-PD deficiency which replaced the role of acetylsalicylic acid(ASA)after acute period.The coronary artery of these patients were checked and followed-up through echocardiograph.The turnover of 32 patients with G-6-PD deficiency and 356 case selected randomly from all the KD patients were compared.SPSS 10.0 software was used to analyze the data.Results In 32 cases of KD with G-6-PD deficiency,4 children had coronary aneurysm(12.5%).After 6-12 months follow-up,the coronary lesions were recovered in 62.5% children,improved in 21.9% children and not improved in 15.6% childern,which were not significantly different from all the KD patients(Z=-1.604 P=1.09).Conclusions IVIG and Dipyridamole are feasible in treating KD with G-6-PD deficiency.J Appl Clin Pediatr,2009,24(1):26-27

OBJECTIVETo observe the effect of tensile stress on human heel skin fibroblast proliferation in vitro, providing a theoretical basis for preventing the wound edge skin necrosis and nonunion after calcaneal fracture surgery.

METHODSFibroblast cells were taken from lateral heel skin of a 40 year-old-man, then cultured and subcultured in vitro. After that, they were divided into three groups: 0 hours group, 6 hours group and 24 hours group and were tested by tensile stress testing. The levels of TGF-β1 and IL-6 in nutrient fluid were measured. Transmission electron microscope and light microscope was applied for observe mitochondria and nucleus.

RESULTSUnder 10% of the tensile stress, mitochondria decreased, the levels of TGF-β1 and IL-6 in nutrient fluid were decreased and cell proliferation was inhibited gradually with time increasing.

CONCLUSIONThe human lateral heel skin in a long-time tensile stress state is an important cause of wound edge skin necrosis and nonunion after calcaneus fracture surgery.

Background Rare studies on the effect of statin on early stage of atherosclerosis have been repor- ted.Oxidative stress induced endothelial dysfunction may be the initiative factor for the development of atheroscle- rotic plague.Objective To investigate the mechanisms by which simvastatin,prevents atheroselerosis independ- ently of its lipid-lowering effect in Apolipoprotein E deficient mice.Methods Twenty-four 6 week old male apoE- deficient mice were randomly to receive placebo or simvastatin 5 mg/(kg?d)by gavage for 4 weeks.Total choles- terol(TC),super oxide dismutase(SOD),malondialdehyde(MDA)and serum nitric oxide(NO)were measured by biochemical analysis.Endothelium was observed by HE dyeing.The expression of caveolin-1 in aortic wall was detected by immunohistochemistry.Results There was no significant difference in serum TC between control and simvastatin treatment groups.Simvastatin caused less damaged endothelium(33.33% vs control's:75%,P

Objective To evaluate the relationship between recurrence of cryptogenic ischemic cerebrovascular disease (CICVD) and patent foramen ovale (PFO),as well as to access the clinical significance of PFO in ischemic cerebrovascular disease.Methods Consecutive patients with CICVD aged 15 to 70 years who were hospitalized in Department of Neurology,Xuanwu Hospital Capital Medical University from January 2008 to March 2011 were prospectively investigated.Identified by transesophageal echocardiography,patients were divided into two groups with respect to outcome:PFO group and non-PFO group.The recurrence of cerebral ischemic events was compared between the two groups after neurological follow-up.Results A total of 91 patients were recruited,including 57 patients with PFO and 34 patients without PFO.The follow-up period of two groups was 695 (506,1142) d.The recurrence rate at 15 months in patients with PFO (24.5％ (12/49)) was higher than those without PFO (6.9％ (2/29),x2 =4.391,P =0.036).Cum hazard curve indicated that recurrence risk of cerebral ischemic events in patients with CICVD in PFO group was higher than that of patients in non-PFO group during the follow-up period (P =0.044).Cox model used for multivariate survival analysis indicated that PFO was a risk factor for cerebral ischemic event recurrence among patients with CICVD (OR =4.159,95％ CI 1.178-14.689,P =0.027).Conclusions PFO is associated with increased recurrence risk of cerebral ischemia in CICVD patients.In addition,PFO may be a significant factor for ischemic cerebrovascular disease.

Objective To evaluate the efficacy and adverse effects of docetaxel combined with 5-fluorouracil in treating patients with advanced gastrice cancer.Methods 130 patients with advanced gastric cancer were randomly divided into observation group and control group,observation group treated with docetaxel combined with 5-fluorouracil,the control group treated with 5-fluorouracil and cisplatin,the clinical efficacy after the treatment was observed.Results The clinical efficiency rate of the observation group was significantly higher than that of the control group,the rate of leukopenia,thrombocytopenia and gastrointestinal reactions of the observation group was significantly lower than the control group,the quality of life scores of the two groups after treatment were all improved,but that of the observation group was significantly higher than the control group,the difference was statistically significant(P ＜ 0.05).Conclusion Docetaxel combined with 5-fluorouracil was effective in treating advanced gastric cancer.It worth further clinical research and application.

Objective To explore the effects of coincident infection on treatment response and coronary artery lesion (CAL) outcome in children with Kawasaki disease(KD).Methods A retrospective study of 141 children diagnosed on KD between Jul.2005 and Dec.2006 were performed.Standardized clinical assessments,laboratory examinations microbiology test results plus treatment regimens were reviewed.CAL were visualized by using echocardiography.Infectious agents positive (INF+) and negative (INF-) groups were identified,and clinical assessments,laboratory and treatment data were analyzed.Results 1.Concurrent infections:41%(58/141) of children had one of above confirmed infection at KD diagnosis.2.Treatment response:the presence of infection did not alter the response to treatment with intravenous immunoglobulin (IVIG),with resolution of fever within 72 h in 85% (120/141) children after 1 dose of IVIG (2 g/kg) together with aspirin administration regardless of present or absent infection.3.CAL outcome:in total,56.0% (79/141) of children developed CAL at the time of diagnosis,involving dilatation (91.1%,72/79 cases) and aneurysm (8.9%,7/79 cases),and no giant aneurysm was found.Most CAL were recovered within 1 year after treatment.Incidence of aneurysm in INF+ group was significantly higher than that in INF-group (P=0.019).Conclusions Coincident infection would not affect on the clinical assessment,laboratory test results and treatment response to IVIG in children with KD,but would result in higher risk of serious CAL.Therefore,children with infection at diagnosis on KD will not only accept active treatment in acute phase,but also insist on convalescent care and follow-up visit.
