Objective To investigate the detection results of GHB with different instruments, and to provide reliable basis for improving the accuracy of GHB detection. Methods ADVIA 1650 biochemical analyzer and HA-8160 glycosylated hemoglobin analyzer were used. The accurate detection of glycosylated hemoglobin in 100 healthy people was carried out, and the related data were recorded and analyzed statistically. Attention should be paid to this group according to glycosylated hemoglobin detection value, that is, within 6.5% for A group, 6.5%-10.0% for B group, more than 10% for C group, and compare the above-mentioned different grouping of corresponding instrument glycosylated hemoglobin detection value. Results The analysis showed that there was no significant difference between the two groups of C instrument glycosylated hemoglobin levels, but the level of glycosylated hemoglobin detected by A in group HA-8160 and group B was significantly higher than that of ADVIA 1650(P<0.05). Conclusion Different instruments have some differences in the detection value of glycosylated hemoglobin. Clinicians should judge the disease comprehensively according to the actual situation and other indicators.

OBJECTIVE:To study the influence of calcineurin gene polymorphism on the efficacy of cyclosporine A (CsA). METHODS:The blood samples of patients treated with CsA were collected. The trough blood concentration of CsA was detected by EMIT. The genotype of PPP3CA and PPP3CB was assayed by RFLP-PCR method. The expression of NFAT-regulated gene IL-2, IFN-γand GM-CSF were measured by RT-qPCR,which were used to define the index of indirect efficacy of CsA. The relationship of gene polymorphism with CsA efficacy was study by relationship analysis and multiple factor regression method,etc. RESULTS:A to-tal of 100 blood samples were collected. There was no significant correlation between the expression of CsA efficacy-related NFAT-reg-ulated gene GM-CSF and trough concentration of CsA(rGM-CSF=-0.04,P=0.238);the expression of IL-2 and IFN-γ were negatively correlated with trough concentration of CsA significantly(rIL-2=-0.384 3,P<0.001;rIFN-γ=-0.335 4,P<0.001). Using the average value of mRNA expression of IL-2 and IFN-γas indirect efficacy index,the polymorphism of PPP3CB rs3763679 site significantly in-fluenced the efficacy of CsA(P<0.05),but PPP3CA rs3804358 had no any effect on it(P>0.05). Stratified analysis showed that among patients with immune disease underwent renal transplantation,efficacy of patients with PPP3CB rs3763679 genovariation(TC+TT) were better than those with wild-type gene (CC)(P<0.05). After the efficacy was normalized by CsA trough concentration, multivariate analysis showed that normalized efficacy of CsA was negatively correlated with gender,PPP3CB rs3763679,lactate dehy-drogenase and creatinine significantly,but positively correlated with PPP3CA rs3804358,leucocyte count,usea nitrogen,glycerin trilaurate,etc. CONCLUSIONS:PPP3CB rs3763679 gene polymorphism influence the efficacy of CsA;among patients with immune disease underwent renal transplantation,efficacy of patients with PPP3CB rs3763679 TT+TC is better than that of CC type. At the same time,gender,PPP3CA rs3804358,leucocyte count,usea nitrogen,glycerin trilaurate and other factors all can influence the nor-malized efficacy of CsA to different extent. Multiple factors should be considered when using CsA.

Objective To evaluate the efficiency and the timing of continuous blood purification(CBP) in patients with multiple or-gan dysfunction syndrome(MODS) and acute renal failure(ARF) following cardiac surgery. Methods From November,2003 to July,2007,thirty-one patients with MODS and ARF following cardiac surgery were treated with CBP. They were divided into two groups, alive group ( group A) and dead group ( group B). Clinical data of the two groups were reviewed. Before CBP, duration of extracorporeal circulation, du-ated. Mean arterial pressure (MAP), heart rate (HR), oxygenic index (PaO2/FiO2), white blood cell count (WBC), platelet count (PLT) and renal function (blood urea nitrogen, BUN, ercatinine, Cr) were observed before and after CBP. Results The number of im-paired organs of patients in group B was significantly more than that in group A before CBP ( P<0.05). MODS scores ( 12.9±3.2 vs 6.9 ±2.3, P<0.05) and APACHE Ⅱ scores (26.3±10.4 vs 17.2±5.1, P<0.05)of group B were significantly higher than those of group A before CBP. After treatment of CBP for 24 hours, APACHE Ⅱ scores and MODS scores only significantly decreased in group A (P<0.05 ). After treatment of CBP, Cr and BUN significantly reduced, while MAP and PaO2/FiO2 increased, in all patients, but HR was signif-icantly lower than that before CBP in group A (P<0.05). The duration of ARF (34.67±32.79 hours vs 13.05±14.09 hours,P<cantly higher than those of group A. Conclusion MODS scores and APACHE II scores can be used to evaluate the severity of patients with MODS and ARF after cardiac surgery. CBP is an effective treatment for these patients. It is suggested that early CBP therapy is important for reducing the chances of the multiple organ dysfunction syndrome and mortality of these patients.

Aim: Synthesized N-acylated chitosan(NAC) was used to anchor on the surface of plain docetaxel li-posomes( PDL) in order to to sustain drug release. Methods; NAC of low substitution degrees were prepared using hexanoic(C_6), lauric( C_(12)), and palmitic( C_(16)) anhydrides. W-palmitoyl chitosan was chosen to anchor the do-cetaxel liposomes. In vitro release profiles of conventional liposmes and the anchored liposomes was compared. Results: Hexanoic(C_6), lauric( C_(12)), and palmitic( C_(16)) -branched chitosans were synthesized. It was found that N-acylated chitosan-anchored DXL liposomes (NDL) increase stabilities of docetaxel liposomes. 70% of docetaxel was released from PDL in 24 hours but 39% from NDL Conclusion: Liposomes anchored by the low substituted N-acylated chitosan could decrease the drug release.
