Background Erythropoietin (EPO) was proved to be express in hematopoietic tissue and nervous system and play the effects of stimulating blood cell production and protecting nervous tissue.Researches showed that EPO is expressed in the embryon brain of animal.However,whether EPO exist in nervous-derived retina and its action on retina with the development is concerned. Objective This research was to investigate the expression of EPO during the embryonic development period of rat retina and explore the role of EPO in retina development process.Methods Clean Wistar rats with pregnancy for 12 days,16 days and 20 days were collected,and the embryonic 12-day rats (E12 d,5 rats),embryonic 16-day rats (E16 d,5 rats) and embryonic 20-day rats ( E20 d,5 rats) were obtained by caesarean operation,and 5 12-month W istar rats were used as controls.The rats were sacrificed by cervical dislocation and the retinal sections were prepared in the different-embryo-phase (12 d,16 d,20d) and growth phase.The expression of EPO protein and mRNA in rat retina was detected by immunohistochemistry and reverse transcription-polymerase chain reaction (RT-PCR),respectively.The feed and use of the animals followed the Regulation for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission.Results EPO was positively expressed in the cytoplasm and nuclei in the neuroepithelial layer and pigment epithelium of every-embryo-phase rats but only in retinal ganglion cell layer in 12-month-old rats.The gray scale values of EPO expression in retina were 105.55±10.35,99.35± 8.71,83.27± 7.84and 30.30± 3.80 in E12 d rats,E16 d rats,E20 d rats and 12-month-old rats respectively with a statistically significant difference (F=76.13,P＜0.01 ).RT-PCR revealed that the relative values of EPO mRNA expression in retina were 0.876±0.10,0.861 ±0.09 and 0.256±0.03 in E16 d rats,E20 d rats and 12-month-old rats respectively,presenting a elevated value in embryonic rats compared with adult rats ( P =0.00).Gel imaging deletion showed that the A value of EPO amplification products was highest in E16 d rats and lowest in adult rats.Conclusions The expression of EPO appears a high to low fashion during the embryonic development of Wistar rats,which is closely associated with the developing procedure of retina.

In total, 607 bedridden patients aged 60 years and over at Tianlin community hospital and four other hospitals or at home-care in Shanghai were investigated with questionnaire, physical examinations and related laboratory tests. Contents of investigation include general situation, medical conditions, 24-hour recall of diet, intake of nutritional supplement preparation, and so on. As compare to the reference for nutrient intake of the elderly set in the Guide to Diet for Chinese Residents (2007), total nutritional intake was obviously insufficient and three nutrients in diet were imbalanced for most bedridden elderly patients. Intake of most nutrients (including proteins, dietary fiber, calcium, iron, zinc, selenium,copper, magnesium, phosphor, retinol equivalent, vitamin B1 , vitamin B2, vitamin C) was obviously low in bedridden elderly patients, with a larger gap from the requirements of the Dietary Guide.

Both sides of the picornavirus genome have 5'-untranslated region (5'UTR) and 3'- untranslated region (3'UTR). This study demontrated that both the 5'-and 3'-UTR can form complex structures, such as stem-loop, clover and pseudoknot structure, These structures play an important role in the regulaton of the replication and translation of the viruses. This article reviewed the progress of research on the structure and function of picornavirus' 3'-UTR over recent years.

The specific fragment of Pneumococcal surface protein A(PspA)and Pneumococcal Surface Adhesin A(PsaA)gene was amplified by PCR from Streptococcus pneumonia 5 and Streptococcus pneumonia 19.The amplified fragnent of PspA and PsaA gene was ligated into pET-27b(+)vector and transformed into BL 21 E.coli for expression and obtain the expressive production of PspA and PsaA.Induced by IPTG,the expression level was as high as 75 % of the total disolube protein.The result showed that the recombinant plasmid could express a specific 75 kDa and 37 kDa fusion protein in E.coli BL 21,which showed the good immunogenicity and a broadly cross reactivity with the other serotypes.

Abstract: Objective To establish the duplex TaqMan RT-PCR method for detection of Entamoeba histolytica and Giardia lamblia in fecal samples. Methods Primer pairs and probes for Entamoeba histolytica and Giardia lamblia were designed and duplex TaqMan RT-PCR amplification system was constructed. PCR products were inserted into the pUC57 plasmid, and the lower limit of detection of the method was determined. Clinical stool samples were tested in order to evaluated the efficacy of the method. Results The detection limits of duplex TaqMan RT-PCR were 31.6 copies/μL for Entamoeba histolytica and 32 copies/μL for Giardia lamblia, respectively. Of the total of 212 clinical stool samples tested, all 3 samples with E. histolytica-positive patients by microscopy were positive by PCR, while 1 from 209 samples with E. histolytica-negative patients by microscopy were positive by PCR, and the remaining samples were negative. For Giardia lamblia, all 8 samples positive by microscopy were positive by PCR, and 1 from 204 sample with a microscopy-negative patient was positive by PCR, and the remaining samples were negative. The amplification product sequencing and blast analysis were used to confirm that the amplified sequence in the specimen of a patient with negative microscopy but positive PCR belongs to the targeted pathogen, supported by clinical symptoms and laboratory test results. PCR results for other diarrhea-causing pathogens were negative, indicating no cross-reactivity. Conclusions The dual TaqMan RT-PCR method developed in this study can not only detect microscopy-positive samples of Entamoeba histolytica and Giardia lamblia but also can detect samples that were missed by microscopy, with higher sensitivity than the microscopy method. Further, this detection method does not cross-react with other diarrhea-causing pathogens, including cross-react with other diarrhea-causing pathogens including Iodamoeba butschlii, Blastocystis hominis, Plesiomonas, Aeromonas, Salmonella, Shigella, Sphaerozoum fuscum, and Entamoeba hartmani, thus has a good specificity.

Objective To compare the mutation sites in human immunodefieiency virus type 1 (HIV-1) vpr gene via of HIV-1 infected individuals from different regions in China with the previous studies, and to provide information for the further study on the relationship between HIV-1 vpr gene mutations and clinical conditions of the patients. Methods Reverse transcription-polymerasc chain reaction (RT-PCR) and nested PCR were used to amplify HIV-1 vpr gene of 398 HIV-1 infected individuals. The amino acid sequences were analyzed to determine polymorphisms, deviation rate and common mutation sites of HIV-1 vpr gene. Meanwhile, the viral load, subsets of lymphocytes and clinical course of patients infected with mutated HIV-1 were analyzed. Results One hundred and fifty three positive samples which were obtained from 398 HIV-1 infected individuals were available for further analysis. The amino acids sequence typing of HIV-1 Vpr were showed that CRF01 AE was 51.63%, subtype C 24.84%, subtype B 17.65%, CRF03_ AB 3.92% and CRF08 BC 1.31%. Eighty four point three percent of 77th amino acid of HIV Vpr sequence was glutamic acid which was significantly different from what overseas researches reported that the R77Q mutation was correlated with long-term non-progression (LTNP) of AIDS. The mutations of the, 63th, 70th, 85th, 86th, 89th and 94th amino acids of HIV Vpr were likely related to the clinical remission of HIV-1 infected individuals. Conclusions M group is the main type of HIV Vpr typing in China, and CRF01 AE is predominant. Some amino acid mutation sites of HIV-1 Vpr are possibly correlated with clinical manifestations of HIV-1 infected individuals.
