Diabetes is the general chronic metabolic disease,with chronic hyperglycemia as the main clinical characteristic.Proteomics discusses and explores the pathogenesis of diabetes more deeply from the overall level of proteins,which has been frequently applied in Chinese medicine research.This paper summarized proteomics application in the study of Chinese medicine intervening diabetes mellitus,including screening and verification of proteomics in Chinese medicine syndromes of diabetes and its complications,as well as proteomics analysis of pharmacological mechanism of related Chinese medicine.This paper also prospected its outlook,in hope toprovide new clues and basis for the pathogenesis theory of diabetes in traditional Chinese medicine (TCM) and functioning targets,and to deepen research on Chinese medicine intervening diabetes.

The SRY gene from buffalo (Bubalus bubalis) genome was amplified by the polymerase chain reaction ( PCR) with primers based on the sequence of Hostein SRY gene. The amplified fragment was 2005 bp include 5UTR ( 1 - 504bp) and 3'UTR(1196 - 2005bp). And the amplified fragment was cloned and sequenced. Sequence analysis showed that the coding region of SRY gene (505 - 1195bp) from buffalo was highly homologous with those of other bovine counterpart genes (96% homology) , especially in the HMG box region (99%homology). It was found that there were only signal on male buffalo genome on Southern blot,which indicate SRY gene are highly conservative on evolves.

?AlM: To investigate the expression of miR-181 in the lens tissue of cataract and the regulating mechanism of miR-181 on apoptosis of human lens epithelial cell.
?METHODS:Real time q-PCR was used to measure the expression of miR-181 in the anterior lens capsules of age - related cataract and human lens epithelial cell apoptosis model. miR- 181 mimic and inhibitor were transfected using Lipofectamine 2 000 to regulate the expression of miR-181, and then Real time q-PCR was used to verify transfection efficiency. Flow cytometry was used to detect the change of cell apoptosis rate.
? RESULTS: Compared with control group, the expression of miR-181 was significantly higher in both the anterior lens capsules of age-related cataract and human lens epithelial cell apoptosis model; the relative expression of miR-181 in lens epithelial cells transfected with miR-181 mimic was increased, whereas decreased in cells transfected with miR-181 inhibitor;the apoptosis rate of cells transfected with miR - 181 mimic was increased, while reduced in miR-181 inhibitor group. Each result was statistically significant (P<0. 01).
?CONCLUSlON:High expression of miR-181 is detected in anterior lens capsule of age-related cataract. miR-181 might play a certain role in the pathogenesis of cataract via promoting human lens epithelial cell apoptosis. miR-181 probably becomes a new approach for the nonoperative treatment of cataract, but the concrete mechanism still needs to be further studied.

Objective To explore the etiology,clinical manifestations of infantal viral pneumonia in Luzhou area.Methods Five viral specific serum IgM antibodies were detected by enzyme-linked immunosorbent assay(ELISA) in acute period of viral pneumonia.Five kinds of virus were separated,as respiratory syncytial virue(RSV),influenza virus(IFV),adenovirus(ADV),cytonegalo virus(CMV),and parainfluenza virus(PIV).Serum specific IgM was positive,C-reactive protein(CRP) was less than 8 mg/L,and there was no(clini-)cal and laboratory proof of other pathogenic infection detected in 221 infants with pneumonia.Results 1.One hundred and four cases of viral infection were detected from 221 infants with pneumonia.The viral positive detected rate was 47.1%,and there were 75 cases of single viral infection(72.1%) and 29 cases of mixed viral infection(27.9%) among them.2.In the single viral infection,RSV was the first,IFV,ADV,PIV and CMV being the second,the third,the fourth,and the fifth respectively.3.The types of likely infection virus were different in different age-stage and seasons in infants.Conclusions The etiology of infantal pneumonia is complicated.The types of viral infection are various besides germ infection and the epidemic season peak;clinical manifestations are different.Earlier detection of(etiology) in infection will make clear the etiology and then take appropriate treatment measures to improve curative effect.

Objective To set a rapid,simple gene diagnosis method for Down syndrome.Methods Three short tandem repeats(D21S11,D21S1270,D21S1437)loci in or near Down syndrome critical region(DSCR) were analyzed and detected by polymerase chain reaction and DNA quantitative analysis in 11 core ancestry.Results There were four types by DNA quantitative analysis to different individuals at a short tandem repeats(STR) locus.In type one,a homozygote of one allelic gene was detected.In type two,a normal heterozygote of two allelic genes was found,the content or two DNA electrophoresis bands was approximately 1∶1.In type three,a Down syndrome patient of two allelic genes was discovered.The quantity of two electrophoresis bands was nearly 2∶1.In type four,the patient showed three DNA electrophoresis bands which the content was approximately 1∶1∶1.Conclusion A rapid gene diagnosis and prenatal diagnosis method for Down syndrome can be used for quantitative analysis of STR polymorphism loci.

Objective To study the possible relationship between the psychological health of children with hematuria and their mothers.Methods Sixty children with hematuria were tested with podiatric symptom checklist(PSC),and the findings were compared with 60 healthy children.The mothers of the patients were assessed by self-rating anxiety scale(SAS),compared with the mothers of healthy children.Results The scores of PSC in patients were higher than those in healthy children(P

The optimum condition of shaking-flask p roducing enzyme were the tempe rature 26℃,initial pH 6 4,fermentation period 19 hours,medium volume 15mL m e dium/300mL Flask.soymilk-clotting enzyme was obtained from ammonium sulfate p r ecipitation.The optimum temperature and pH for the soymilk-clotting activity wa s 70℃and 5 8.The enzyme was easy to lose activity in acid or alkaline circumst a nce.About 60% of the original activity remained after 1 hour at 60℃.Ca 2+ ,Fe 2+ , Mg 2+ ,Na +increased the clotting activity,whereas Zn 2+ ,Al 3+ ca use inhibition.

The purity of 4,4′-dimethoxy-5,6,5′,6′-bis (methylenedioxy)-2′-morpholine methylenebiphenyl-2-methyl formate methanesulfonate (IMH), a new drug for fatty liver treatment, was determined through differential scanning calorimetry (DSC). Analysis of two-factor non repeatability method was performed in the investigation the effects of two factors (heating rate and sample weight) on purity determination. The DSC experimental parameters were optimized as follows: heating rate was 10 ℃·min^-1, temperature range was 150-300 ℃, sample weight was 2.0-4.1 mg, and N₂ flow rate was 80 mL·min^-1. The linear correlation coefficient (r) of this DSC method was 0.999 8. The RSD value (n = 6) of precision was 0.03%. The standard value and uncertainty of the purity results of the multiple batches of IMH drugs were (99.74 ± 0.29)%, (99.91 ± 0.28)%, (99.90 ± 0.28)%, and (99.81 ± 0.28)% with inclusion factor (K) of 2 and confidence probability (P) of 0.95. The results were basically consistent with the results of the mass balance method. The DSC mehod is a simple, rapid and accurate method, and provides a new reference method for determining the purity of IMH drugs, improves the accuracy and reliability of purity determination.
