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.

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.

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.

OBJECTIVETo evaluate the application of multi-detector row CT (MDCT) and CT angiography (CTA) for detecting early signs of acute bowel ischemia (ABI) in experimental porcine models.

METHODSTwelve pigs were assigned to four groups with 3 in each group. The digital subtraction angiography of superior mesenteric artery (SMA) and the embolization of branches of SMA with gelatin sponge and blood clot were performed by percutaneous transfemoral artery puncture and catheterization. MDCT pre- and post-contrast scanning in the arterial, venous and delay phase and CTA with three-dimensional reconstruction were carried out at pre-operation, 3 h, 6 h, 9 h, and 12 h after occlusion. The normal mesenteric vascular anatomy, arterial occlusion, mesentery and bowel changes, and dynamic change were evaluated.

RESULTSABI changes were identified pathologically in all the 12 experimental pigs, and the severity of ischemia increased over time after embolization. CTA showed all 57 embolized branches of SMA and 29 of 34 unoccluded arterial branches with 5 false-positive vessel occlusions. The sensitivity and specificity of CTA were 100% and 85.3%, respectively. Thin-slab maximum intensity projection (TSMIP) revealed the disappearance of distal comb-like vessel branches and brush-like vasa recta, which were clearly delineated in the normal bowel segments. Using this criterion, TSMIP correctly defined 23 of 24 ischemic bowel segments and all the 12 normal bowel segments with a sensitivity of 95.8% and a specificity of 100%.

CONCLUSIONSMDCT and CTA reliably define normal and occluded mesenteric vessels in the pig. It can easily detect ischemic bowel segment by identified early changes of ischemia. The early direct ischemic signs are occluded vessels, the disappearance of distal comb-like branches or brush-like vasa recta, and poor bowel enhancement. The early indirect sign is bowel dilatation with fluid collection.

Transgenic Atropa belladonna with high levels of scopolamine was developed by metabolic engineering. A functional gene involved in the rate limiting enzyme of h6h involved in the biosynthetic pathway of scopolamine was over expressed in A. belladonna via Agrobacterium-mediation. The transgenic plants were culturing till fruiting through micropropogating and acclimating. The integration of the h6h genes into the genomic DNA of transgenic plants were confirmed by genomic polymerase chain reaction (PCR) analysis. Analysis of the difference of plant height, crown width, stem diameter, leaf length, leaf width, branch number and fresh weight was carried out using SPSS software. The content of hyoscyamine and scopolamine in roots, stems, leaves and fruits was determined by HPLC. The investigation of the expression levels of Hnh6h by qPCR. Both Kan(r) and Hnh6h genes were detected in five transgenic lines of A. belladonna plants (A8, A11, A12, C8 and C19), but were not detected in the controls. The plant height, crown width, stem diameter, leaf length, leaf width, branch number and fresh weight of transgenic plants did not decrease by comparison with the non-transgenic ones, and furthermore some agronomic characters of transgenic plants were better than those of the controls. The highest level of scopolamine was found in leaves of transgenic A. belladonna, and the content of scopolamine was also higher than that of hyoscyamine in leaves. The contents of scopolamine of leaves in different transgenic lines were listed in order: C8 > A12 > C19 > A11 > A8, especially, the content of scopolamine in transgenic line C8 was 2.17 mg x g(-1) DW that was 4.2 folds of the non-transgenic ones (0.42 mg x g(-1) DW). The expression of transgenic Hnh6h was detected in all the transgenic plants but not in the control. The highest level of Hnh6h expression was found in transgenic leaves. Overexpression of Hnh6h is able to break the rate limiting steps involved in the downstream pathway of scopolamine biosynthesis, and thus promotes the metabolic flux flowing toward biosynthesis of scopolamine to improve the capacity of scopolamine biosynthesis in transgenic plants. As a result, transgenic plants of A. belladonna with higher level of scopolamine were developed.

OBJECTIVETo evaluate the influence of Shenfu Injection (SHF) on the quality of life of patients with advanced non-small cell lung cancer (NSCLC) receiving chemotherapy.

METHODSA total of 133 patients with NSCLC receiving at least two cycles of chemotherapy with taxol plus cisplatin (TP)/vinorelbine plus cisplatin (NP) or gemcitabine plus cisplatin (GP) were randomized into SHF pre-treatment group (with SHF given only in the first cycle) and SHF post-treatment group (with SHF given only in the second cycle). The Quality of Life Questionnaire-Core 30 (QLQ-C30) and the Functional Living Index-Cancer (FLIC) were used to evaluate the quality of life of the patients after the treatments.

RESULTSBoth of the groups showed improved quality of life after the treatments (P<0.01), but the improvements were more obvious in SHF pre-treatment group (P<0.05). SHF showed favorable effects in relieving such adverse effects as fatigue, nausea, vomiting and diarrhea associated with the chemotherapy.

CONCLUSIONSHF can improve the quality of life in NSCLC patients receiving chemotherapies.
