Objective To explore the effects of peripheral stem cell transplantation on extremely severe bone marrow form of acute radiation sickness.Methods One patient was radiated aecidently with the radiation dosage of 9~15 Gy and diagnosed as extremely severe bone marrow form of acute radiation sickness.Pretreatment was performed at 4th day after the accident and 3 days later,HLA- matched allogeneic stem cell transplantation on the patient was performed.Graft versus host disease (GVHD) was prevented with cyclosporin A (CsA) and mycophenolate mofetil (MMF).Results The haematopoiesis was recovered at 9th day after transplantation.At 11th day after transplantation, WBCs were increased to 14.74?10~9/L and returned to the normal levels subsequently,number of platelets risen to 51?10~9/L and hemaglobin was over 80 g/L.TRS-PCR and blood type dynamic detection testified that the donor's cells were stably implanted,the chromosome aberration and micro- nuclei disappeared after transplantation,and the patient's blood type changed into the donor's at 27th day after transplantation.But the radiation injury were still getting worse complicated with multiple infections,At 68th day after transplantation (75 days after the accident),the patient was died of mul- tiple organs failure.Conclusion Extremely severe bone marrow form of ARS can achieve hematopoie- sis recovery by allogeneic stem cell transplantation,but only hematopoiesis recovery can not cure the immunodefficiency and the radiation injury of the whole body.

There exist a number of mercury-resistant bacterial in environment, Mer operon is involved in the resistant mechanism, MerRTPA of Mer operon encodes the proteins related to the regulation, transport and reduction of mercury ion, respectively. The toxic mercury ion is transported by MerTP from medium to cytoplasmic mercuric reductase, MerA, and deoxidized to non-toxic and volatile element mercury, Hg(0). Bacterial mercury-resistant system originated from ancient times, and evolved into the Mer operon with diversity by gene integration and insertion. Mercury-resistant bacteria highly specifically absorb mercury ion, and can be used in recovering the mercury-polluted environment as well as the genetic selective marker.

Objective To explore the effect of community comprehensive rehabilitation on quality of life in patients with stroke sequelae under the family medical service mode. Methods From October, 2013 to October, 2014, 51 patients with stroke sequelae received compre-hensive rehabilitation intervention for three months, including rehabilitation training, rehabilitation guidance, health education and psycho-logical counseling. They were assessed with modified Barthel index (MBI), WHO-Disability Assessment Schedule (WHO-DASⅡ), Short Form 36 Health Survey Questionnaire (SF-36), Brain Injury Community Rehabilitation Outcome Scales (BICRO-39), Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS) before and after intervention. Results The scores of physical functionning, role physical, general health, mental health, social functioning and the total score in SF-36 increased after intervention (t>2.072, P<0.05). The scores of so-cial contact, locomotivity, self handling transaction ability and the total score in BICRO-39 decreased after intervention (t>2.434, P<0.05), as well as the scores of getting along with people, housework and society and participation in WHO-DAS II (t>2.507, P<0.05). Conclusion In the community health service, comprehensive rehabilitation guided by multidisciplinary rehabilitation team can facilitate to improve the quality of life in patients with stroke sequela.

Fermentation condition optimization of P. decumbens Ju-A10 for production of CMCase using three kinds of plant cellulosic wastes as carbon sources was made using RSA method. The result was that CMCase was the highest when the level of carbon source was 9. 77 % , 8. 69 % and 9. 97% , and liquid volume was 64. 7 mL, 54. 2 mL, 40. 8 mL for carbon sources of millet straw, wheat straw and paper sludge, respectively. The value of CMCase was 29. 26IU/mL, 29. 14 IU/mL, 29. 81 IU/mL, respectively, in the above cases. The value of R2 is 0. 9117 , 0. 9246, 0. 8655 , respectively. It could be concluded that the fermentation models were quite reliable. The method can be applied in optimization of fungi fermentation medium.

Objective To study the influence of electro-acupuncture(EA)at Zusanli points(足三里穴) on the apoptosis of thymocytes in rats with abdominal infection and its mechanism.Methods A total of 40 Sprague-Dawley(SD)rats were randomly divided into four groups,including normal control group,model group,non-acupoint group and Zusanli group.The abdominal infection model of rat was made by cecal ligation and puncture(CLP).After abdominal cavity infection for 36 hours,the apoptosis of thymocytes was observed under electron microscope and light microscope,and the apoptosis ratio of thymocytes was determined by Annexin V-PI method with flow cytometry technique.The content of Bcl-2 protein of thymocytes and concentration of corticosterone in plasma were determined.Results Abdominal infection resulted from CLP could significantly increase the apoptosis of thymocytes and lead to the typical histopathological changes of apoptosis of thymocytes under electron microscope and light microscope.Apoptosis ratios of thyrnocytes in model group[(44.7?3.3)%],non-acupoint group[(42.7?3.0)%]and Zusanli group[(32.6?3.3)%] were significantly higher than the ratio in the control group[(21.2?2.3)%,all P0.05).Abdominal infection resulted from CLP also could reduce the content of Bcl-2 protein of thymocytes.The content of Bcl-2 protein of thymocytes in model group(71.2?5.6),non-acupoint group(73.5?5.9)and Zusanli group(82.4?6.8) were significantly lower than normal control group(95.3?6.3,all P

Objective To compare the sub-cellular proteome of isoniazid ( INH)-resistant Mycobacterium tuberculosis (MTB) with that of sensitive strains for identifying of unique proteins of these strains and discussing their preliminary application in clinical diagnosis. MethodsProteins of cell wall and membrane of 5 INH-resistant strains and 5 INH-sensitive strains were extracted by density gradient centrifugation.The extracts were subsequently analyzed using weak cation exchange (WCX) liquid chromatography ( LC )followed reverse phase (RP) liquid chromatography to compare the sub-cellular protein patterns. A total of 1280 fractions were collected and identified by matrix assisted laser desorption ionization-time of flight-tandem mass spectrometry (MALDI-TOF MS/MS). The Database for Annotation, Visualization and Integrated Discovery (DAVID) was used for cell component and biological process analysis. Normalized Spectral Abundance Factors (NASF) was used for semi-quantity of protein expression. 5 proteins significantly up-regulated in INH-resistant strains and 2 proteins significantly up-regulated in INH-sensitive strains were selected for ELISA analysis with autologous sera respectively. Results A total of 347 proteins were identified. Cell component analysis showed that 58% proteins were cells well or membrane proteins. Biological process analysis showed that 31% proteins involved in carboxylic/monocarboxylic acid biosynthetic and metabolic process, 26% and 15% proteins involved in organic acid or fatty acid biosynthetic and metabolic process,while 28% proteins involved in lipid biosynthetic , metabolic, transport and localization process. O-succinylbenzoate synthase, monooxygenase, hypothetical protein Rv2255c, nicotinate-nucleotide--dimethylbenzimidazole phosphoribosyltransferase and membrane phosphatidate cytidylyltransferase cdsA were up-regulated in INH-resistant strains and fractions contained these proteins could elicit specific antibody response with autologous sera. The A450 was higher than that with INH-sensitive sera. The differences between the INH-resistant sera and the INH-sensitive sera were significant ( t = 0.028, 0.044, 0.066, 0.064, 0.083, all P<0.01 ). Chain A of Rv2002 Gene Product and Chain A of Crystal Structure Of Rv2632c were up-regulated in INH-sensitive strains and fractions contained these proteins could elicit specific antibody response with autologous sera. The A450 was higher than that with INH-resistant sera. The differences between the INH-sensitive sera and the INH-resistant sera were significant (t=0.053, 0.073, both P<0.05). ConclusionThe combination of density gradient centrifugation and 2D-LC MS/MS technology is useful in enrichment and identification of differential expressed proteins between INH-resistant and INH-sensitive strains at sub-cellular level. It is useful in finding antigens associated with INH-resistant MTB infection, which may prove useful for further study in the mechanism of INH resistant, as well as interaction between MTB and host.
