OBJECTIVETo evaluate the radiosensitivity and toxicity of sodium glycididazole and cisplatin in concurrent chemoradiotherapy for local advanced nasopharyngeal carcinoma (NPC).

METHODSSixty patients with local advanced NPC (T3-4N2-3M0) were randomly divided into chemoradiotherapy group (n=30) and chemoradiotherapy plus sodium glycididazole group (n=30). All the patients received radiotherapy with (60)Co or 6-8 MV linear accelerator and concurrent injection of cisplatin at a weekly dose of 20 mg/m square. In sodium glycididazole group, the patients received injections of sodium glycididazole at 800 mg/m square prior to the radiotherapy 3 times a week.

RESULTSAt the end of the therapy and 3 month after the radiotherapy, a response rate of 100% was achieved in both of the groups. But at the end of the therapy, the chemoradiotherapy plus sodium glycididazole group showed a significantly higher rate of complete tumor remission than the chemoradiotherapy group (93.3% vs 73.33%, chi(2)=4.32, P=0.038). The patients in the two groups showed similar tolerance of the therapy during the observation.

CONCLUSIONSodium glycididazole plus cisplatin can accelerate the tumor remission and improve the complete remission rate in patients with local advanced NPC without causing severe toxicity.

OBJECTIVEThe objective of this study is to investigate the influence of zirconia content which is 0-30.0% weight percentage of matrix on translucency of zirconia-toughened alumina glass-infiltrated ceramics.

METHODSSeven groups were divided according to different weight percentage of zirconia (0, 2.5%, 5.0%, 7.5%, 10.0%, 20.0% and 30.0%). After sintering, infiltrating and polishing, spectral transmittance was determined with spectrophotometer under D65 standard source. Contrast ratio was also tested by whiteness colorimeter.

RESULTSWith mass fraction of zirconia increasing from 0 to 30.0%, spectral transmittance reduced from 0.406% to 0.058%, while contrast ratio value increased from 0.849 +/- 0.005 to 1.015 +/- 0.006. When zirconia content was 10.0%, contrast ratio was 0.990 +/- 0.008. When it was more than 10.0%, transmission rate of the downward trend and contrast ratio of the rising trend became flat.

CONCLUSIONZirconia content has a direct impact on translucency of zirconia-toughened alumina glass-infiltrated ceramic, which is essentially opaque when zirconia content is 10.0%. When mass fraction of zirconia is more than 10.0%, the influence of zirconia content is reduced.

OBJECTIVEAge, body weight and dose have been shown as important influencing factors for sodium valproate plasma concentrations. However it is unclear whether there is interaction among them and whether the interaction could influence sodium valproate plasma concentrations. This study aimed to evaluate the influence of age, body weight and dose on plasma concentrations of sodium valproate and the interaction among them.

METHODSOne hundred and thirty-two children with epilepsy (age: 4 months-6 years, weight: 5-25 kg) were enrolled. Sodium valproate was administered at the dosage of 10-30 mg/kg/d. Plasma concentrations of sodium valproate were measured by high-performance liquid chromatography 3-5 days after administration. The relationship of sodium valproate plasma concentrations with age, body weight, and dose of sodium valproate was examined using variance analysis, pearson correlation analysis and stepwise regression analysis.

RESULTSAge (F=8.630, P<0.01), body weight (F=3.650, P<0.05) and dose of sodium valproate (F=11.720, P<0.01) were influencing factors for sodium valproate plasma concentrations. The interaction between age and oral dose (F=2.484, P<0.05) and the interaction of age and body weight with oral dose (F=4.923, P<0.01) had significant effects on sodium valproate plasma concentrations. Stepwise regression analysis showed that dose of sodium valproate and body weight were entered to the regression equation.

CONCLUSIONSAge, body weight and dose of sodium valproate as well as the interactions between age and dose and between age, body weight and dose were influencing factors for valproate plasma concentrations.

Objective To evaluate the enhanced magnification endoscopy in the diagnosis of Barrett esophagus,and to explore the relationship between mucosal surface patterns and pathological epithelial types of Barrett esophagus.Methods Enhanced magnification endoscopy was performed 'after spraying 2%-3% acetic acid on the surface of distal esophagus in 40 Barrett esophagus patients.Mucosal specimen were biop- syed.Results According to the mucosal types of Toyoda in 2003,there were three mucosal types:Ⅰ dot pat- tern 7(17.5%),5 of 7(71.4%)fundie type,Ⅱ reticular pattern 24(60.0%),16 of 24(66.7%)fundic type,Ⅲ cerebroid/villous 9(22.5%),intestinal metaplasia or dysplasia.Conclusion Enhanced magnifi- cation endoscopy helps to identify areas with intestinal metaplasia and dysplasia,and is useful in the diagno- sis of Barrett esophagus.

The capacity of reverse cholesterol transport (RCT) of lipid loaded cells is critical of atherosclerosis(AS) development.Autophagy is an important regulatory mechanism promoting RCT.But the exact effects of autophagy activation or inhibition on RCT remain unclear in AS.So in this review we suggest that partly inhibition of autophagy or induction of lysosomal biogenesis improves the autophagy capacity of lipid loaded cells.

Objective To observe the therapeutic effect of ketogenic diet therapy for children with intractable epilepsy and its safety.Methods Fifteen patients with intractable epilepsy were treated with ketogenic diet that was modified specifically for Chinese people.The compliance,seizure frequency and side effects were followed up.Results Twelve patients maintained on the treatment for 1 month.Among them,the reduction of seizure frequency in 10 patients exceed 50%.Ten patients maintained on the treatment for 3 months.Among them,the reduction of seizure frequency in 8 patients exceed 50%.Five patients maintained on the treatment for more than 6 months.The reduction of seizure frequency all exceed 50%.The reduction of seizure frequency in 4 patients exceed 90%.The seizures of 3 patients were controlled completely.Ten patients among all cases had various adverse effect,such as nausea,vomiting,diarrhea,constipation,hypoglycemia(nonsymptomatic),hyperlipemia and damage of liver function and so on,which could eliminate by anti-symptomatic treatment.Conclusions Ketogenic diet is effective and safe in Chinese children with intractable epilepsy with modified methods specifically for Chinese.The effect is unrelated with seizure types obviously.

OBJECTIVEP-glycoprotein 170 (P-gp) is a plausible biologic candidate for pharmacoresistance in epilepsy. The expression and efflux efficiency of P-gp is influenced by a polymorphism (C3435T) in the encoding gene (MDR1). The CC genotype at the MDR1 C3435T polymorphism was reported to be associated with the response to antiepileptic drug treatment. This study attempted to replicate this finding by examining the association of this genetic polymorphism with response to antiepileptic drug treatment in ethnic Han Chinese children with epilepsy.

METHODSTwo hundred and fourteen ethnic Han Chinese children with epilepsy were classified based on the response to antiepileptic drug treatment: drug-nonresponsive and drug-responsive. DNA samples were obtained from the patients. Genotypes of the C3435T polymorphism were determined by traditional polymerase chain reaction followed by restriction digestion (PCR-RFLP). The frequency of genotypes and alleles between the two groups was compared by Chi-square test.

RESULTSOf the 214 patients, 164 were drug-responsive and 50 were drug-nonresponsive. There were no significant differences in the allele frequency and genotype frequency between the two groups.

CONCLUSIONSThere is no an association between the CC genotype or C allele at the locus of C3435T in MDR1 gene and response to antiepileptic drug treatment in ethnic Han Chinese children with epilepsy.

OBJECTIVETo evaluate the efficacy and safety of recombinant human granulocyte-macrophage colony stimulating factor (rhGM-CSF) hydrogel in wound healing in patients with deep partial thickness burn.

METHODSThe study was a multicenter, randomized, double-blind, placebo-controlled parallel clinical trial. Three hundred and twenty-one patients (302 cases finally fulfilled the protocol) with deep partial thickness burn were divided into A group (n = 200, with treatment of rhGM-CSF hydrogel, 100 microg/10 g/100 cm2/d), C group (n = 102,with treatment of placebo). Side-effect, systemic condition, wound healing time, wound healing rate, and total effective rate at different time points were observed.

RESULTSThere were no obvious differences in vital signs, wound secretion, wound edge reaction, blood and urine routine, liver and kidney function between two groups (P > 0.05). No side-effect was observed. The median wound healing time was 17 days in A group, which was obviously shorter than that in C group (20 days, P < 0.01). The mean wound healing rate in A group was 24.5%, 70.5%, 95.3%, 99.6% respectively on 8th, 14th, 20th, 28th day after treatment, which were obviously higher than that in C group (15.1%, 51.4%, 84.6%, 97.1%, respectively, P < 0.01). The total effective rates in A group on 8th, 14th, 20th day after treatment were also higher than that in C group (P < 0.01).

CONCLUSIONrhGM-CSF hydrogel can significantly accelerate wound healing in patients with deep partial thickness burn with certain safety.
