AIM:To investigate the role of mesenchymal stem cell-induced regulatory dendritic cells ( MSC-DCregs) in mouse acute graft-versus-host disease( aGVHD) model.METHODS: Bone marrow cells from BALB/c ( H-2 d ) mice were isolated and were induced to differentiate into DCs.The DCs were selected by flow cytometry, and after 10 d co-culture with MSCs, they were induced to be MSC-DCregs.Male 8-week-old C57BL/6 (H-2b) mice were used as do-nor mice.The female 8-week-old BALB/c (H-2d) mice, who had received 100 cm source-skin distance, 30 cm ×30 cm radiation field, 700 cGy total body irradiation (TBI) pretreatment were used as recipient mice.The recipients were divided into 5 groups:control group, TBI group ( injected with medium only) , bone marrow transplantation group ( injected with 1 ×107 bone marrow cells), aGVHD group (injected with 1 ×107 bone marrow cells and 1 ×107 spleen cells), and MSC-DCregs group (injected with 1 ×107 bone marrow cells, 1 ×107 spleen cells and 1 ×106 MSC-DCregs).The white blood cell count, recipients’ chimerism, clinical evaluation of aGVHD, survival analysis and pathological changes were deter-mined.RESULTS:Hematopoieic recovery was seen at 10 d after transplantation.The recipients’ chimerism was parallel to the donors’ at 30 d.The median survival time of the mice in aGVHD group and MSC-DCregs group was 27 d and 33 d, and the survival rates at 30 d were 20% and 100% (P<0.01), respectively.The clinical scores of the mice in MSC-DCregs group were lower than those in aGVHD group ( P<0.01) .Moreover, the pathological changes in the skin and liver of the mice in MSC-DCregs group were less serious than those in aGVHD group.CONCLUSION: The MSC-DCregs in-duce an aGVHD tolerance in vivo, and further research of its mechanism is still in great necessary.

OBJECTIVEUsing methods of clinical scale assessment and cerebral functional imaging to compare the relative specificity of needling acupoints Baihui (DU20), Shuigou (DU26) and Shenmen (HT7) in intervening vascular dementia (VD) in different areas in the brain.

METHODSFifty patients with VD were randomized into 5 groups. Needling on conventionally used acupoints of hand and foot three Yang-meridians aiming at hemiplegia was applied to the patients in Group A, and needling on DU20 to Group B, on DU26 to Group C, on HT7 to Group D and on all the three to Group E was applied additionally. Assessments of Mini Mental State Examination (MMSE), Activities of Daily Living (ADL) and Family Attitude Questionnaire (FAQ) were made. And the positron emission computerized tomography (PET) and single photon emission computerized tomography (SPECT) examinations were conducted in 5 selected patients from each group before and after treatment.

RESULTSNeedling on conventional acupoints plus DU20 could effect the inner temporal system, thalamencephalon system and prefrontal cortical system to improve memory and executive capacity of VD patients; conventional acupoints plus DU26 could effect more to the prefrontal cortical system to obviously elevate the executive capacity; that plus HT7 would reveal an effect similar to but rather weaker than plus DU20, and effect more to memory; and that plus all the three simultaneously could effect rather roundly multiple aspects of the nervous system related to intellectual activities, to elevate the recognition and enhance the executive capacity.

CONCLUSIONNeedling on various acupoints like DU20, DU26 and HT7 have effects on different brain areas.

Objective To develop a clinically useful assay for detecting the mutations of HBV pre-C/BCP based on the pyrosequencing and accuracy, reproducibility and reliability of this assay was evaluated. Methods The pyrosequencing primers for HBV pre-C/BCP mutation were designed through the cluster analysis among one hundred HBV gene sequences. After the amplification of the fragment of pre-C/BCP with the template of pre-C/BCP mutation plasmids, the pyrosequencing method for pre-C/BCP detection was initially set up with this standard sample. The accuracy, reliability and reproducibility of the pre-C/BCP pyrosequencing were confirmed through the pre-C/BCP plasmids as a standard sample when compared with Sanger/genechip sequencing method pre-C/BCP pyrosequencing assay was applied for detecting pre-C/BCP mutation types of 60 chnical serum samples in HBV patients. Results The pre-C/BCP mutation detection assay based on pyrosequencing has been established in our study. The coincidence rate between pyrosequencing and Sanger squencing was 100%. The coincidence rate between the result of pyrosequencing and of genechip method was 91.7%. The reproducibility of this assay was 97. 8%. It indicates the pre-C/BCP pyrosequencing is a high-accurate method with, good-reproducibility and high-reliability. And multi-site detection can be achieved by pyrosequencing one time. A rare mutation T1758C was also detected. Conclusion Pyrosequencing for pre-C/BCP mutations assay is high-throughout method for simultaneous detection of multi-site mutation.

Objective To express,purify and identify recombinant hepatitis E virus(HEV) pb166-GST fusion protein using GST gene fusion system and investigate its potential role in researching Hepatitis E diagnostic antigen field.Methods The recombinant E.coli BL21 performed by our own laboratory was used to induce the HEV pb166-GST expression with IPTG.The products were purified by BD Biosience GST purifying system.The specific expression was identified by SDS-PAGE and Western blot.The experiment conditions and results were described and analysed.Results The resolved HEV pb166-GST fusion protein on SDS-PAGE showed a major band at position of 43 kD.The expressed proteins had a single expected band after purify and the protein was recognized by anti-GST antibody on PVDF membrane.Conclusion The recombinant HEV pb166-GST fusion protein is expressed in recombinant E.coli BL21 efficiently in this way,and might be used as a candidate for diagnostic antigen of HEV.

OBJECTIVETo investigate the anatomical features of iliac bone grafts used for mandibular reconstruction and dental implantation.

METHODSSixteen cadavers were dissected. The length, width, height and cortical thickness of the iliac bone were measured with respect to points determined by the relative dimensions of the bone.

RESULTSThe length of iliac bone graft was (77.2 ± 6.1) mm. The height was from (38.2 ± 4.2) mm to (41.9 ± 4.7) mm. The width decreased from iliac crest to base line. The least width 10 mm and 15 mm away from iliac crest were (8.4 ± 2.2) mm and (6.5 ± 2.1) mm respectively. The greatest mean cross-sectional cortical thickness at the intermediate line of the iliac crest was (3.4 ± 0.8) mm.

CONCLUSIONSAnatomical features of iliac bone are suitable for designing bone grafts for mandibular reconstruction followed by dental implantation.

Viewing from some TCM concepts and basic characteristics of health, assimilating the operationalization concerning thinking and procedure of modern scientific research, the pilot form of Health Scale of TCM--initial health scale of TCM (iHSTCM) based upon TCM theory was developed. From November 2002 to January 2003, the domain, facets and items of HSTCM were finally established by analyzing the data from a survey of 652 persons in Guangzhou City using iHSTCM. In conclusion, the HSTCM has its theoretical ratio-nality and is applicable. It could be further applied in TCM clinical practice.
