Objective To seek for the differentially-expressed proteins in patients with kidney-yin deficiency syndrome and to screen out the specific proteins,so as to provide evidence for the establishment of objective standard of kidney deficiency syndrome of traditional Chinese medicine (TCM).Methods Five patients with typical kidney-yin deficiency syndrome and 6 normal healthy volunteers were enrolled into the study.Plasma proteins in both groups were detected by antibody chip,and then the plasma proteins profile was compared and analyzed.Results A total of 25 differentially-expressed proteins between kidney-yin deficiency group and normal control group were found,of which 2 were up-regulated and 23 were down-regulated.Conclusion The differentially-expressed proteins in patients with kidney-yin deficiency syndrome are mainly related to immune disorder,protein biosynthesis,metabolism,oxidative stress,cell apoptosis,signal transduction,and so on.

AIM: To evaluate the influence of the calpain system mRNA and protein expression on the progress of atrial structural remodeling in fibrillating canine.METHODS: 17 dogs were randomly divided into 2 groups: normal control group(SR,n=6) and atrial fibrillation(AF,n=11) group.AF was induced by rapid pacing for 8 weeks and all dogs underwent transthoratic echocardiography before and after rapid pacing.The mRNA and protein expression of calpainⅠ,calpainⅡand calpastatin were assessed by real-time quantitative PCR and Western blotting,respectively.RESULTS: Compared with SR group,the left atrial diameters and the content of calcium in atrial myocardium increased significantly in AF group(P0.05) between two groups.The expression of calpastatin mRNA was upregulated significantly in AF group(P

Atractylodis Macrocephalae Rhizoma and Atractylodis Rhizoma were widely used in strengthening spleen under different disease conditions, and were easily and often misused each other. Therefore, DNA barcode was used to distinguish Atractylodis Macrocephalae Rhizoma and Atractylodis Rhizoma from their adulterants to ensure the safe use. The sequence lengths of ITS2 of Atractylodes macrocephala, Atractylodis Rhizoma (A. lancea, A. japonica and A. coreana) were both 229 bp. Among the ITS2 sequences of A. macrocephala, only one G/C transversion was detected at site 98, and the average GC content was 69.42%. No variable site was detected in the ITS2 sequences of A. lancea. The maximum K2P intraspecific genetic distances of both A. japonica and A. coreana were 0.013. The maximum K2P intraspecific genetic distances of A. macrocephala, A. lancea, A. japonica and A. coreana were less than the minimum interspecific genetic distance of adulterants. The ITS2 sequences in each of these polytypic species were separated into pairs of divergent clusters in the NJ tree. DNA barcoding could be used as a fast and accurate identification method to distinguish Atractylodis Macrocephalae Rhizoma, Atractylodis Rhizoma, from their adulterants to ensure its safe use.

Objective:To prepare a kind of G418 resistance fibroblast feeder layers.Methods: In order to prepare a stock primary embryonic fibroblast (EMFI) cells, the pregnant Smad3ex8+/- mice containing heterozygous neo gene were killed 14 days after coitus to get the embryo. EMFI cells were tested by PCR to identify their gene types. Only one EMFI cell which contained heterozygous neo gene was chosen and treated with mitomycin C.The mitomycin C-treated EMFI feeders were stored at -70℃. Results: The EMFI feeder layers could support the growth of embryonic stem cell line TC-1 efficiently and could live in G418 resistance medium for 1-2 weeks.

AIM:To study the feasibility of recombinant adeno-associated virus(rAAV)as a vector to transfer the green fluorescent protein(GFP)gene as a target gene into rabbit retina.METHODS:Intravitreal injection of rAAV-gfp was performed in either eye for each rabbit with the other eye taken as control.At the 3rd,7th,and 14th day after injection,the eyeballs were removed,and the retinas were flat-mounted on glass slides to inspect the retinal fluorescence,respectively.RESULTS:After intravitreal injection of rAAV-gfp,the presence of fluorescent spots in the cytoplasm of retinal cells indicated that GFP gene was efficiently transferred and expressed in the rabbit retina.CONCLUSION:Recombinant adeno-associated virus is a reliable and simple vector for transferring target gene,e.g.,GFP gene,to the retina.

Objective To investigate the prevalence and incidence of Keshan disease (KD) and the selenium concentration of food and hair in residents of Yongjin Village, Fuyu County, Heilongjiang Province, national monitoring site, in 2007. Methods According to the Standard of Keshan Disease Surveillance and the Standard of Diagnosis of Keshan Disease(GB 17021-1997), the residents living in the monitoring site were surveyed by clinical examination and electrocardiography. For individuals whose hearts showed abnormalities, a chest X-ray photograph was taken. The selenium concentrations of the residents' food (flour) and hair were assayed by flowing injection hydride generation atomic fluoremetric method(FI-HG-AFM). Results Nineteen KD patients were found from 282 residents in 2007 KD surveillance. The prevalence of KD, latent KD and chronic KD were 6.7%(19/282), 2.8%(8/282) and 3.9%(11/282), respectively. Five of the 8 latent KD cases were newly found. In addition, there were 5 the suspected KD cases, including 2 suspected chronic KD cases. No acute KD or sub-acute KD patients were found in Yongjin Village at this monitoring site this year. The average selenium concentration of children hair and residents food were (0.3197±0.0586)mg/kg and (0.0210±0.0062)mg/kg, respectively. Conclusions New cases of KD continued to emerge, indicating that etiological factors still exist. Therefore, the emphasis of monitoring KD in furore is founding the consummate report of infectious disease system and training the personnel to increase the reliability of monitoring.

Objective To observe the perioperative myocardial protection of high-dose atorvastatin to acute coronary syndrome(ACS) patients during percutaneous coronary artery interventional therapy(PCI).Methods One hundred and twenty patients with ACS undergoing elective PCI were divided into group A and group B with different oral dose of atorvastatin ( 80 mg/d and 20 mg/d ) for 3 days before operation by random digits table. Troponin I (cTnI), creatine kinase isozyme MB (CK-MB), high sensitive C-reactive protein (hs-CRP), interleukin (IL)-6 levels were measured before operation, 6 hours, 12 hours after operation and total cholesterol (TC), triglyeride (TG), low desity lipeprotein cholesterol (LDL-C), high density lipeprotein cholesterol (HDL-C) levels were measured before operation and 3 days after operation.Results cTnI,CK-MB,hs-CRP and IL-6 levels in the two groups were increased significandy 6 hours and 12 hours after operation (P <0.05). Six hours after operation, cTnI and CK-MB levels in group A were significantly lower than those in group B [(0.35±0. 18 ) μg/L vs. (0.48±0. 16 ) μg/L, ( 3.78±0.45 )μg/Lvs. (4.56±0.55 )μg/L] (P < 0.05 ). Twelve hours after operation , hs-CRP and IL-6 levels in group A were significantly lower than those in group B [(4.53±0.98 ) mg/L vs. (7.03±0.88 ) mg/L, ( 30.6±11.2) ng/L vs.(43.8±12.1) ng/L] (P <0.05). TC, TG, LDL-C, HDL-C levels in the two groups did not change significantly before and after operation (P >0.05). Conclusions Myocardial protective effects of ACS patients treated with atorvastatin 80 mg/d for 3 days are better than those treated with oral atorvastatin 20 mg/d. High-dose atorvastatin can produce more beneficial effects.

Objective To construct a suitable system of professional degree of prevention and health care of TCM postgraduates based on practical ability. Methods Dephi method was used to carry out two rounds of questionnaire survey on 30 experts from top three hospitals and TCM colleges and universities in different regions to evaluate the level of experts' initiative, authority and coordination. Results After 2 rounds of inquiry, it was concluded that the prevention and health care professional postgraduate training practical ability mainly included clinical ability (100%), research ability (73.3%), management ability (76.7%) and education ability (90.0%). On the basis of this, 11 compulsory courses and 5 elective courses were established, and clinical practice was built at the same time. Conclusion This study of professional degree courses for prevention and health care of TCM postgraduates on the construction based on practical ability training is feasible.
