To study the effects of conjee and cooked rice on postprandial glucose and plasma insulin levels in type 2 diatetes,and to help diabetic patients select reasonably food.41 diabetes were divided into cooked rice group ( group A),conjee with steamed bread group ( group B),and oatmeal group ( group C ).At 1 h after meal,the values of postprandial plasma glucose (PPG) was significantly lower in group C than those in group A and group B [ ( 11.17± 2.30 vs 12.88 ± 1.29,13.29 ± 1.97 ) mmol/L,P ＜ 0.05 ].At 2 h after meal,the value of PPG was significantly lower in group C than in group A [ ( 8.88 ± 2.66 vs 10.87 ± 1.63 ) mmol/L,P ＜0.05 ].At 1 h and 2 h after meal,there was no significant difference between the value of PPG in goup A and group B ( P＞0.05 ).At 1 h after meal,the value of plasma insulin was significantly lower in group C than those in group B [ (46.02 ± 26.32 vs 88.56 ± 68.75 )μU/ml,P ＜0.05 ],and there was a littler higher in group B than group A ( P＞0.05 ).At 2 h after meal,there was no statistical difference of plasma insulin among group A,B,C [ ( 57.10 ± 33.56,62.26 ± 24.42,54.16 ± 41.35 )μU/ml,P＞0.05 ) ].Isocaloric oat food is potentially beneficial in sustaining blood glucose status and decreasing insulin secretion.It is the ideal choice for type 2 diabetes.Meanwhile,there were no statistical differences in PPG and insulin levels between the individuals taking conjee with steam bread and cooked rice.

BACKGROUNDThis study was undertaken to obtain differentially expressed genes related to human glioma by cDNA microarray and the characterization of a novel full-length gene.

METHODSTotal RNA was extracted form human glioma and normal brain tissue, and mRNA was used as a probe. The results of hybridization procedure were scanned with the computer system. The gene named 507E08 cone was subsequently analyzed by northern blot, bioinformatic approach, and protein expression.

RESULTSFifteen differentially expressed genes were obtained from human glioma by hybridization and scanning for four times. Northern blot analysis confirmed that the 507E08 clone was low expressed in human brain tissue and over expressed in human glioma tissues. The analysis of BLASTn and BLASTx showed that the 507E08 clone was a novel full-length gene, which codes 203 amino acid of protein and is called human ribosomal protein 14.22 gene. The nucleotide sequence had been submitted to the GenBank with the accession number of AF329277. After expression in E. coli., protein yielded a major band of apparent molecular mass 22 kDa on an SDS-PAGE gel.

CONCLUSIONScDNA microarray technology can be successfully used to identify differentially expressed genes. The novel full-length gene of human ribosomal protein 13.22 may be correlated with the development of human glioma.

A total of 127 type 2 diabetic patients were divided into low glycemic index meal replacements (intervention) group and standard food-based diet (reference) group in an experiment for 12 weeks.The results showed that fasting plasma glucose,postprandial 2 h plasma glucose,fasting insulin,and homeostasis model assessment insulin resistance(HOMA-IR) in the intervention group decreased significantly after 12 weeks trial ( P＜0.05 or P＜0.01 ).However,there were no significant changes in lipid profile and HbA1C in intervention group.In addition,percentage of body fatty,visceral fatty area,and waist-hip ratio also decreased in intervention group( all P＜0.01 ).Superoxide dismutase and glutathione levels increased significantly in intervention group by the end of trial (both P＜0.01 ),while malondialdehyde was decreased (P＜0.01 ).There were no significant changes in the aforementioned indices in the reference group.Weight,body mass index,and waist circumferences were decreased in both groups,but without significant difference between the two groups.

OBJECTIVETo investigate the renal function in newborns with birth asphyxia or intrauterine distress in the first week of life.

METHODSSixty full-term newborns born between June 2002 and February 2003 were assigned into three groups: Control group (healthy newborns), Intrauterine distress group (Apgar score > 7), and Birth asphyxia group without intrauterine distress (12 mild asphyxia and 8 severe asphyxia) (n=20 each). Urinary levels of alpha1-microglobulin (alpha1-MG), beta2-microglobulin (beta2-MG) and albumin (Alb) were detected by radioimmunoassay at 0-2, 3-4 and 6-7 days after birth.

RESULTSThe urinary levels of alpha1-MG, beta2-MG and Alb in the Asphyxia group were significantly higher than those in the Control group at all time points (P < 0.05), peaking at 3-4 days after birth. Statistically significant differences were found between the severely and mildly asphyxiated newborns for the urinary levels of alpha1-MG, beta2-MG and Alb at all time points (P < 0.05). There were no significant differences in the urinary levels of alpha1-MG, beta2-MG and Alb between the Intrauterine distress and the Control groups at each time point.

CONCLUSIONSBirth asphyxia may lead to renal glomerular and tubular impairments and it is speculated that the most serious impairment occurs at the 3rd and 4th days of life. The severity of renal impairments is associated with the degree of asphyxia. The renal function of the newborn appears to be normal following intrauterine distress.

Objective To evaluate the clinical efficacy and safety of oxiracetam combined with nimodipine on cognitive impairment patients with type 2 diabetes and to investigate its mechanisms.Methods Ninety patients with cognitive impairment in type 2 diabetes were randomly divided into oxiracetam group (A) (n =30) with oxiracetam 800 mg, tid, po;nimodipine group (B) (n=30) with nimodipine 20 mg, tid, po;and combined group (C) (n=30) with oxiracetam plus nimodipine of the same dose.After tweleve-week treatment,the Montreal cognitive assessment ( MoCA ) and activities of daily living ( ADL ) scale were evaluated.Neuron -specific enolase ( NSE ) and S -100βprotein expressions in blood serum and drug adverse reactions were also evalua-ted.Results After tweleve-week treatment, MoCA score was signifi-cantly increased ( P<0.05 ) and ADL scale was significantly reduced in all of the three groups ( P <0.05 ) , and the changes in the C group was much more obvious than other two groups (P <0.01).After treatment, NSE and S-100βprotein expressions in blood serum of group A and B were obviously reduced compared with before treatment ( P <0.05 ) , while group C were more dramatically reduced compared with A and B group ( P <0.01 ) . No obvious side effect was observed in the period of treatment in all the three groups. Conclusion Oxiracetam combined with nimodipine treatment was superior to either of the single regiment in the treatment of cognitive impairment in type 2 diabetes without increasing the risk of developing side effect by inhibiting NSE and S-100βexpressions.

Objective To observe the risk factors of the short-term prognosis of anti-N-methyl-D-aspartic acid (anti-NMDAR) encephalitis.Methods The clinical data of 66 children with anti-NMDAR encephalitis was analyzed retrospectively,and the scores of modified Rankin scale (mRS) were used before and after treatment.According to the treatment results,the children with mRS less than or equal to 2 points were used as treatment group,those with mRS score more than 3 points were set as the control group.Single factor and multiple factor Logistic regression analysis were used to analyze the risk factors of poor prognosis.Results Of the 66 cases,39 had good prognosis and 27 had poor prognosis.The results of single factor analysis showed that age,days of hospitalization,epilepsy,dyskinesia,mRS scores score were associated with poor prognosis.Multiple factor Logistic regression analysis showed that age,epileptic seizures,and mRS scores before treatment were independent risk factors for the short-term prognosis of anti-NMDAR encephalitis.Conclusion Patients with anti-NMDAR encephalitis have small age,seizures and high mRS scores before treatment,which may predict poor prognosis in the near future.

BACKGROUNDFamilial hypercholesterolemia (FH) is a type of dominant autosomal disease that causes high levels of plasma low-density lipoprotein cholesterol (LDL-C). In the past years, molecular data related to FH were limited in China. Now, to gain more information about FH, we analyzed one proband with a severe FH phenotype as well as his relatives.

METHODSAfter the entire coding sequence and the intron-exon junctions of the low-density lipoprotein receptor (LDLR) gene were amplified using PCR, we sequenced the LDLR gene of a Chinese FH family. RT-PCR was used to detect changes in the mRNA.

RESULTSTwo novel mutations were identified in the LDLR gene of this family. One, W165X, was a G > A substitution at the third nucleotide of codon 165. The other, IVS5-1G > A, was also a G > A substitution at the acceptor splice site of intron 5. The most striking discovery is that the proband was heterozygous for W165X but homozygous for IVS5-1G > A. The cDNA sequencing showed that the IVS5-1G > A mutation caused the insertion of 10 nucleotides, namely GCTCTCACAA, between exon 5 and exon 6.

CONCLUSIONSThe two nucleotide variations are thought to be the FH-causing mutations because the co-segregation of the mutant allele with the phenotype of FH has been shown in this Chinese family. These data show an increase in the mutational spectrum of FH in China and verify a scarce mutational form in the LDLR gene.

Objective： This study was designed to investigate the three-dimensional quantitative structure-activity relationship (3D-QSAR) and the active sites of podophyllotoxin derivatives. Methods： Twenty-three podophyllotoxin derivatives had been designed to investigate 3D-QSAR against L1210 cells by comparative molecular field analysis (CoMFA), then they were studied by Austin model 1 (AM1) method of quantum chemical calculation. The 3D-QSAR and the active sites were discussed according to their stereo structure and electronic structure. Results： A CoMFA model with considerable predictive ability was established. The results showed that the C4 position was an effective modified point. The steric effect and the electrostatic effect of 4-substituted group were the dominant factor for the activity. The replacement of the “ -NH-” bridge at C4 with the “ -O-” bridge resulted in lowering of the anticancer activity. The results revealed that there was a large electropositive region around the B ring moiety and it could easily combine with an acceptor of the drug. The B ring was essential for the activity. The E ring and its C4′ hydroxyl group also have strong influence on the activity and is an important center of negative electricity within the molecule. Conclusions： The inhibitory activities of the compounds can be predicated by the CoMFA mode. The B ring and E ring are important active sites of the molecule.
