Objective: To study the effect of gait analysis based on digital video and digital image processing in rehabilitation training in patients with stroke. Methods: Twenty patients with unilateral hemiplegia after stroke were selected. Gait analysis by digital video and digital image processing were used to evaluate the parameter changes of the temporal-spatial parameters of bilateral limbs (stride circles, stride length, stride frequency, stride speed, stand phase time) and the joint (hip, knee, ankle joints) angles before and after (3 months) the rehabilitation training. Results: Circled digit oneThe stride length and speed in 20 patients were 0.51 ± 0.12 m and 0.26 ± 0.17 m/s before the rehabilitation training; they were 0.66 ± 0.23 m and 0.33 ± 0.21 m/s after the training (P < 0.05 all). There were no significant differences among the stride circles, stride frequency, and stand phase time before and after the training. Circled digit twoThe flexion angle of the affected ankle joint reduced significantly when first touched ground after the rehabilitation training as compared to that before the training; the maximum extension angle of the standing phase of ankle and hip joints was increased; the flexion angle of knee joint increased at toe-off, so did the extension angle of ankle joint; the maximum flexion angles of knee and hip joints at stride phase was increased; the range of hip joint angle change in sagittal plan was increased, and that of the ankle joint angle was decreased. Before and after the rehabilitation training on the unaffected sides, there were no significant changes in other joint angle parameters, except the increased maximum flexion angle of the knee joint in stride phase (P < 0.05). Conclusion: The gait analysis base on digital video and digital image processing contributes to qualitatively evaluate the gait characteristics and the efficacy of rehabilitation treatment in patients with stroke.

5srRNA was isolated and purified from the reticulocytes of rabbit. It labeled with ~(125)I, then incubated with mouse myeloma cells (SP2/0). By autoradiography it was observed that ~(125)I-SsrRNA could pass into the nuclei of the cells. In a separate experiment, it showed that the incorporation rate of ~3H-TdR into nuclei of SP2/0 after incubation with 5srRNA was decreased as compared with that f control group, hence the result indicates that 5srRNA inhibits DNA synthesis of the SP2/0 cells and it seems to play a role in the regulation of gene expression through its hybridization with DNA sequences of the SP2/0 cells. Thus it is likely that 5srRNA might act as "erythroid denucleation factor".

The present study reported that 5srRNA from reticulocytes of rabbit could pass into the nucleus of mouse myeloma cells SP2/0,and in the mean time DNA synthesis and cells division were markedly suppressed. In a separate experiment, the rRNA was extracted from embryonic liver and erythrocytes of rabbit or rat and analysed by agarose electrophoresis method. The result indicated that the amount of 5srRNA in various period of the development of erythrocyte is changed along with denucleation process. Thus it is likely that 5srRNA of mammalian erythrocyte plays a role in reversing malignant phenotype of tumor cells and promoting denucleation of mammalian erythrocyte through inhibiting DNA synthesis.

AIM: Niflumic acid (NFA) is known as a kind of inhibitor of calcium-activated chloride channel. The inhibition and mechanism of NFA on the proliferation of airway smooth muscle cells (ASMCs) were investigated. METHODS: Using [ 3H]-TdR incorporation method, we examined the effect of NFA (at concentration of 10 and 50 ?mol/L) on the proliferation of primarily ASMCs from BALB/c mouse. With confocal laser scanning microscope the [Ca 2+ ]i in ASMCs exposed to histamine was observed, and the opposed effects of NFA and nifedipine on histamine were also checked. Finally the effect of NFA on expression of MAPK in ASMCs was examined by indirect immunofluorescent assay. RESULTS: Compared with control group, the proliferation of NFA group was reduced markedly with dependent concentration. Histamine significantly improved the [Ca 2+ ]i in ASMCs, but NFA and nifedipine showed the inhibition on the effect of histamine. NFA reduced the level of MAPK expression in ASMCs. CONCLUSION: It is demonstrated that NFA inhibits the proliferation of ASMCs by reducing [Ca 2+ ]i and the expression level of MAPK. [

Because of the population aging,the increase of the stroke patients and the need for rehabilitation,the treatment only in the rehabilitation department of the hospital is far from the satisfaction of people's demands of the service of rehabilitation.It is important to extend the community-based rehabilitation.Compared with the rehabilitation in hospitals,it is more economy,efficiency and convenience for stroke patients in community-based rehabilitation services,and further improve the rehabilitation effect of stroke patients.

OBJECTIVETo explore the clinical efficacy of moxibustion on rheumatoid arthritis (RA) in the patients and the impacts on the inflammatory indices.

METHODSForty RA patients were randomized into an observation group and a control group, 20 cases in each one. In the control group, diclofenac sodium sustained release tablets were used, 0.3 g each time, twice a day; methotrexate tablets were used, 10 mg each time, once a week; folic acid was used, 5 mg each time, once a week. In the observation group, on the basis of the treatment as the control group, moxibustion was added specially on the swelling and painful joints, once a day, 15-20 min each time till: the local skin turned slightly red. The treatment was given once a day, at the interval of 1 day after every 6 treatments. In the two groups, the efficacy was observed after 30-day treatment. Before and after treatment, the rheumatoid factor (RF), high sensitivity C-reactive protein (hs-CRP), erythrocyte sedimentation rate (ESR), disease activity score-28 (DAS-28) and the score of joint symptom and physical signs were observed.

RESULTSCompared with those before treatment, the levels of RF, hs-CRP, ESR, DAS-28 and the symptom scale score were all reduced in the RA patients of the two groups after treatment (all P < 0.05). Compared with the control group, the levels of RF, hs-CRP, ESR, DAS-28 and the symptom scale score in the observation group were improved much apparently (all P < 0.05). The total effective rate was 85.0% (17/20) in the observation group and was 80.0% (16/20) in the control group. The total effective rate in the observation group was apparently better than that in the control group (P < 0.05).

CONCLUSIONMoxibustion as supplement relieves the joint symptoms, reduces the inflammatory reactive indices and improves the clinical efficacy in the RA patients.

In order to enhance the specificity of TNF-α monoclonal antibody to inflamed site, a bispecific antibody BsDb that targets TNF-α and the extra-domain B (ED-B) of fibronectin (FN) was constructed by covalently linking the anti-TNF-α single chain Fv antibody (TNF-scFv) and the anti-ED-B scFv L19 via a flexible peptide linker deriving from human serum albumin (HSA). ED-B is an antigen specifically expressed at the inflamed site. BsDb is expressed in E. coli, identified by immunoblot, and purified with affinity chromatography. This was followed by further examination of its bioactivities and pharmacokinetics. We demonstrated that BsDb retained the immunoreactivity of its original antibodies as it could simultaneously bind to TNF-α and ED-B and neutralize the biological action of TNF-α. In the collagen-induced arthritis mice model, BsDb selectively accumulate in the inflamed joint with a maximal uptake of (12.2 ± 1.50)% ID/g in a single inflamed paw and retain in the inflamed paw for at least 72 h. In contrast, BsDb showed a short serum half-life of (0.50 ± 0.05) h and a rapid clearance from normal tissues. The findings reported herein indicate that BsDb has good specificity to the inflamed site and low toxicity to normal tissues. BsDb is therefore likely to have greater clinical applications in the treatment of rheumatoid arthritis and other autoimmune diseases. This laid a stable basis for its preclinical study.

OBJECTIVETo compare the clinical effective differences between pricking blood combined with moxibustion and west medication for acute gouty arthritis.

METHODSForty patients with acute gouty arthritis were randomly divided into a pricking blood combined with moxibustion group (a combination group) and a western medication group, 20 cases in each one. In the combination group, pricking blood was used at the most painful points of the red turgid and painful joint once three days, total 3 times; moxibustion was applied at the same joint for 15-20 min, once a day. The moxibustion was adopted for 10 days. In the western medication group, 0. 3 g ibuprofen was prescribed orally twice a day for 10 days. The changes of uric acid (UA), high sensitivity C-reactive protein (hs-CRP), erythrocyte sedimentation rate (ESR) and the joint syndrome and symptom score before and after: treatment were observed. Results In the two groups, the UA, the hs-CRP, the ESR and the joint syndrome and symptom scores were lower than those before treatment (all P<0. 05). After treatment, the UA, the ESR and the joint syndrome and symptom scores in the combination group were declined more apparently than those in the western medication group (all P<0. 05). The total effective rate in the combination group was 85. 0% (17/20) which was better than 75. 0% (15/20) in the western medication group (P<0. 05).

CONCLUSIONPricking blood combined with moxibustion could improve the joint symptoms more effectively and the effect is better than ibuprofen orally.

A hybridoma cell line(B10)was established by fusing spleen cells of BALB/c mou- se immunized with human thyroglobulin(HTG) with SP2/0 myeloma cells. An averagefusing rate of 6.3% and antibody-secreting positive well rate of 58.3% were obtained.During the first two months, the supernatant of B10 culture had a titer of 1/128 to1/2048 measured by hemagglutination method, and the ascites was positive at 1/64000-128000 and 1/320000 respectively as measured by hemagglutination and radioimmunoass-ay.The B10 cell line is very stable and has very high activity to produce anti-HTGmonoclonal antibodies. After several times of preservation in liquid nitrogen andpassage in culture for one year,a recent determination shows that cell culture super-natant and ascites still have very high titer,being 1/4096 and 1/1048576 respectively asmeasured by hemagglutination method. The chromosome number of the B10 hybridomacell is 99.5?7.4.The success of the establishment of this cell line is briefly discussed.Attempt to establish diagnostic kit with this monoclonal antibody is being undertaken.
