OBJECTIVETo evaluate the short-term and long-term effects on treatment of neck pain caused by cervical spondylosis with the combination of acupuncture and moxibustion with seed-size moxa cone.

METHODSOne hundred and forty-five patients of neck pain were randomly divided into an acupuncture-moxibustion group (49 cases), an acupuncture group (48 cases) and a moxibustion group (48 cases). Acupoints of Bailao (Extra), Dazhui (GV 14), Jianzhongshu (SI15) and Zhongzhu (TE 3) were adopted for all the 3 groups. Acupuncture was applied at all the acupoints with 20 min needling retention for the acupuncture group. Moxibustion with seed-size moxa cone was used with 5 cones on each point for the moxibustion group. And both acupuncture and moxibustion with seed-size moxa cone were adopted for the acupuncture-moxibustion group. The treatment was applied once every 3 days, and 10 treatments should be finished within 4 weeks. Follow-up should be carried out for 3 months. The short-term and long-term effects were evaluated with the scores of Northwick Park Pain Questionnaire (NPQ) and McGill Pain Questionnaire (MPQ) as the indices of therapeutic effect.

RESULTSThe NPQ score and MPQ score of all the 3 groups after the treating course and the 3-month follow-up were both decreased when compared with those before the treatment (all P<0. 05). The scores of NPQ and MPQ the acupuncture-moxibustion group were lower than that of the other two groups. And the difference had obvious significance (P<0. 05). High efficiency of pain relieving for cervical spondylosis could be found in all the 3 groups, which showed that short-term and long-term effects were good for all the 3 groups. And the highest curative effect could be found in acupuncture-moxibustion group.

CONCLUSIONCombination of acupuncture and moxibustion with seed-size moxa cone has reached a superior effect in short-term and long-term for neck pain caused by cervical spondylosis.

Objective To evaluate the clinical value of susceptibility weighted imaging (SWI)in full-term neonatal hypoxic ische-mic encephalopathy (HIE).Methods Sixty-three neonates with HIE were collected and scanned by Siemens 3.0T superconducting MR scanner.Routine axial conventional MRI scan and axial SWI scan were conducted.Results In 63 neonates,a total of 29 cases with different degree of intracranial hemorrhage were scanned with SWI sequence.A total of 1 5 1 intracranial hemorrhages were found.Conventional MRI sequences were performed in 1 5 cases with different degree of intracranial hemorrhage.Only 78,43 and 88 hemorrhages were found by T1 WI,T2 WI and T2 Flair sequences,respectively.SWI were significantly superior to conventional MRI sequences in displaying the scope and boundary definition of hemorrhage.Conclusion SWI sequence is obviously better than the con-ventional MRI sequences in bleeding detection and displaying hemorrhage stove,and it provides a powerful imaging method for the clinical diagnosis and treatment.

Objective To investigate the value of magnetic resonance (MR)diffusion kurtosis imaging (DKI)in diagnostic classi-fication of astrocytic tumors.Methods 31 patients with astrocytic tumors confirmed by operation and pathology were collected,in-cluding low-grade tumors (WHO gradeⅠ and Ⅱ)in 14 and high-grade ones (WHO grade Ⅲ and Ⅳ)in 1 7.Routine MRI and DKI scan were preoperatively conducted using Siemens 3.0T MR scanner.Mean kurtosis (MK),radial kurtosis (RK)and axial kurtosis (AK)values were calculated in the solid portion of the tumors and the contralateral normal white matter.Results The MK,RK and AK values in tumors were lower than those in contralateral normal white matter,and were significantly higher in high-grade tumors than those in low-grade ones (P <0.05).Conclusion The MK,RK and AK values obtained by DKI reflect the histological structure changes of the astrocytic tumors.DKI is helpful for the diagnostic classification of astrocytic tumors,exhibiting more value in optimi-zing the treatment.

In this study,DNA molecular identification technology and chemical fingerprint method were adopted to evaluate the quality system of precise powder decoction pieces (PPDP) of S.suberectus dunn (SSD).ITS2 sequence was taken as DNA barcode to indentify SSD.Different specifications of PPDP were prepared,their dry extract contents were quantified in contrast with that of original slices.Three batches of SSD original slices were gleaned and the content uniformity,fingerprint and similarity evaluation before and after the mixing and pulverization were valued by HPLC-DAD.As a result,ITS2 successfully and accurately identified the SSD in this study.The extract rate of PPDP was 15.5％,1.11 times as much as the original slices.RSD of inter-assay dissolution of cepicatechin from the original slices was 11.0％,which was reduced to 1.0％ after mixing and preparing into PPDP.The relative peak area of the 14 common peaks identified by fingerpringts were larger,while the RSD values significantly decreased.It was concluded that the PPDP of SSD improved the extraction efficiency and uniformity of the original slices,featuring quite prospective in more reasonable and scientific clinical use.

Objective To investigate the immunologic classification in the patients with acute leukemia (AL) in Xinjiang of China. Methods A panel of monoclonal antibodies (MOAb) and indirect immunofluorescence assay by fluoromicroscope was used to determine the pretherapy immunophenotype of 450 AL. Results 106 cases of acute lymphoblastic leukemia (ALL), 334 cases of acute myelogenous leukemia (AML), and 10 cases belonged to FAB unclassified acute leukemia (UAL) were unalysed. The expression of myeloid antigens in of ALL was seen in 15 % of 106 cases, and lymphoid-associated antigens were expressed in 25 % of 334 AML cases. The most frequently expressed antigen was CD7. The expression of myeloperoxidase (MPO) gene in 295 cases of AL were studied. The expression of MPO gene was observed in positive one of 81 ALL cases, and myeloid cells had different expression for MPO gene. Of the 9 cases of UAL, 6 cases were positive for MPO gene. There were no statistic differences of the expressions of the ALL stages between Han and Wei nationality. The order of myeloid markers expression in AML was as follows: CD_(33)>CD_(13)>CD_(15) inthe Han nationality, and the order of myeloid markers expression in AML was displayed CD(15)>CD(33)>CD_(14) in Wei nationality. Conclusion Analysis of immunophenotype assured accurate lineage diagnosis of AL. Combinatively analyzing the characteristics of AL on morphology, cytochemistry, immunology and MPO mRNA expressions were significant to the diagnosis and therapy of AL.

Objective To study the recovery of the peripheral lymphocyte subsets in patients underwent allogeneic peripheral blood stem cell transplantation (allo-PBSCT) and guide the prevention and treatment of infection. Methods Indirect immunofluorescence assay was used to detect the lymphocyte subsets, such as T cell subsets (CD3, CD4, CD8). B cell (CD19) and natural killer cell(CD56) at 1, 3, 6, 12, 18months post transplantation, in the meantime, lymphocyte subsets of 32 samples from healthy blood donors were tested as normal control values. Results CD+3, CD+4 and CD+8 ceils significantly decreased than that of normal control at 1 month post transplantation, the recovery of CD+3 T cells was within 3-12 months, CD+4 and CD+8 T cells recovered to normal at 6 months and 3 months post transplantation respectively, CD+4/CD+8 ratio were not significantly lower than that of normal control at different stages, CD+4/CD+8 ratio reversed only at 6 months post transplantation. CD+19 and CD +56 T cells recovered quickly and they were more than normal proportion at 3 months post transplantation. The CD+3, CD+8 T cells and CD+4/CD+8 ratio were statistically higher in HLA haploidentical allo-PBSCT patients than that in HLA identical allo-PBSCT at 3 months post transplantation. There were no difference between the two groups at 1, 6, 12, 18 months post transplantation.The patients with cGVHD had significantly higher CD+4 cells than those without cGVHD at 1 month after transplantation. There was no significant difference in all of the lymphocyte subsets at 3, 6, 12, 18 months after transplantation between them. Conclusion Allo-PBSCT has a hastened immune reconstitution, which was not delayed by the incompatibility of HLA and the development of cGVHD.

OBJECTIVETo compare the detection rate of Epstein-Barr virus latent membrane protein 1 (LMP1) 30 base pair deletion in extranodal nasal type NK/T-cell lymphoma with that in chronic inflammation of nasopharynx and tonsillitis; and to analyze the prognostic significance of LMP1 deletion in extranodal nasal type NK/T-cell lymphoma.

METHODSPolymerase chain reaction was used to detect the deletion of LMP1 in 55 cases of extranodal nasal type NK/T-cell lymphoma and 19 cases of chronic inflammation of nasopharynx and tonsillitis. Follow-up information of 1 to 58-month duration was available in 33 patients.

RESULTSIn all the 55 extranodal nasal type NK/T-cell lymphoma cases studied, 9 cases contained the wide-type or predominantly wide-type LMP1. On the other hand, 46 cases contained the deleted or predominantly deleted LMP1. In the non-lymphoma control group, 16 cases contained the deleted or predominantly deleted LMP1. However, no statistically significant difference was found in the detection rate of 30 base pair deleted LMP1 between extranodal nasal type NK/T-cell lymphoma and control group (P > 0.05). The prognosis of deleted or predominantly deleted LMP1 in extranodal nasal type NK/T-cell lymphoma was worse.

CONCLUSIONThough 30 base pair deletion of Epstein-Barr virus LMP1 may not be an important pathogenetic step in extranodal nasal type NK/T-cell lymphoma, it may play some role in tumor progression.

OBJECTIVETo investigate the effect of small interfering RNA (siRNA) targeting human vascular endothelial growth factor (hVEGF) on A549 cell growth in nude mice and angiogenesis on chorioallantoic membrane (CAM) assay.

METHODSThree pairs of hVEGF siRNA-plasmid and non-silencing-plasmid were constructed, and transfected into A549 cells through lipofectamine 2000, respectively. The most effective pair of hVEGF siRNA-plasmid was selected by ELISA and real-time RT-PCR. A549 cells transfected with selected hVEGF siRNA- plasmid, A549 cells transfected with non-silencing-plasmid and A549 cells without transfection were inoculated into nude mice, respectively. Chick embryos were randomly divided into four groups and CAM was treated by different solutions for 48 h: culture media DMEM as negative control group,un-transfected A549 cell culture supernatants as positive control group, hVEGF siRNA A549 cell culture supernatants as hVEGF siRNA group and nonsilencing siRNA A549 cell culture supernatants as non-silencing siRNA group. The CAMs were harvested on d12 for microscopic assays.

RESULTCompared with control group, hVEGF siRNA-plasmid induced 48% reduction in hVEGF secretion by A549 cells accompanied by 70% reduction in hVEGF mRNA. Compared with non-silencing siRNA group, the mean tumor volume of murine xenograft was reduced by 58% in hVEGF siRNA group; time for xenografts growing to 50 mm(3)was delayed by 5.4 d. hVEGF contents in xenograft were reduced by 54%; but mean doubling time of tumors and the growth rate of tumors were not significantly reduced. In CAM assays, hVEGF content was zero in negative group, and in hVEGF siRNA group that was 40%-44% of non-silencing siRNA group or positive group; vessels branch points of CAM in hVEGF siRNA group or non-silencing siRNA group or positive group were increased by 45%-55% compared with negative group; total vessel length of CAM in hVEGF siRNA group was increased by 53% compared with negative group, while in non-silencing siRNA group or positive group that was increased by 97% or 99%. Compared with negative control group, the proliferation of microvessels was increased when cell culture supernatant with hVEGF was added in hVEGF siRNA group, significant proliferated vessels were observed in non-silencing siRNA group or positive group.

CONCLUSIONA plasmid-mediated hVEGF siRNA has been constructed and verified, which can effectively downregulate the expression of hVEGF in human A549 cells, resulting in the inhibition of angiogenesis. hVEGF siRNA can delay initial growth of A549 tumor xenograft but not reduce the growth rate.
