Objective:To observe the clinical efficacy of fire-needle therapy in treating deglutition disorders due to pseudobulbar palsy in the remission stage of stroke.Methods:Sixty-two eligible subjects were divided into a fire-needle group and a rehabilitation group by a simple randomization method at a ratio of 1:1.The two groups received same basic intervention;in addition,the fire-needle group received fire-needle treatment,while the rehabilitation group received rehabilitation training.The two groups of subjects all received a 3-week treatment and were evaluated by the dysphagia severity rating scale (DSRS),modified Mann assessment of swallow ability (MMASA) and Kubota Toshio swallow test (KTST) before and after the intervention.The complications and adverse events occurred during the trial were recorded.The data were statistically analyzed.Results:At the third week,the DSRS,MMASA and KTST scores changed significantly compared with the baseline in both groups (P＜0.05),and the changes in the fire-needle group were more significant than those in the rehabilitation group (P＜0.05).The between-group comparison at the third week showed that the therapeutic efficacy in the fire-needle group was superior to that in the rehabilitation group (P＜0.05).Conclusion:Fire-needle therapy can obviously change the DSRS,MMASA and KTST scores in pseudobulbar palsy in the remission stage of stroke,and significantly enhance the therapeutic efficacy of the treatment of deglutition disorders in this stage.

OBJECTIVETo observe the effect of Suyu capsule on behavior, injury of hippocampal neurons and Ca2+ ion in hippocampal synaptic in the depression model mice.

METHODSixty male Kunming mice were randomly divided into 5 groups, the control group, the model group and three Suyu capsule groups (the doses were 22.8, 11.4, 5.7 g x kg(-1) respectively). The model was established by separation and chronic unpredictable mild stimulation. The increased weight and crossing score, rearing score were measured by open-field and sweet water consumption of mice. Cone cell and configuration of neuron in CA1, CA3 region of hippocampus were observed by Nissl. The concentration of hippocampal synaptic Ca2+ ion was detected by fluorimetry.

OBJECTIVETo improve computer-assisted imaging analysis for quantitatively measuring brain slice volume of rats and mice in comparison with conventional measuring methods,and to evaluate its usefulness in assessment of focal cerebral ischemia.

METHODSThe accurate volumes of rat and mouse brain slices were measured by weight and special gravity measuring. The areas of brain slices were measured by imaging analysis, then the slice volumes of right and left hemispheres were calculated by multiplying the adjusted thickness of the slices. In addition, the brain slice volumes of right and left hemispheres from focal cerebral ischemic mice were compared to assess ischemic injury using the imaging analysis.

RESULTArea measurement by computer-assisted imaging analysis was linear with different accurate areas (r=1.000). Slice volumes measured by imaging analysis correlated well with the accurate volumes measured by special gravity method, r=0.809 (n=45, P<0.001) in rats, and r=0.844 (n=74, P<0.001) in mice. The brain volumes in ischemic hemispheres were larger than in non-ischemic hemispheres in ischemic mice.

CONCLUSIONComputer-assisted imaging analysis can measure the brain slice volumes accurately and compare right and left hemisphere volumes quantitatively.

OBJECTIVETo compare the difference in the clinical efficacy on cervical spondylosis between acupuncture at three lines of cervical Jiaji (EX-B 2) and oral administration of jingfukang granules.

METHODSThree hundred cases of cervical spondylosis were divided into an acupuncture group and a medication group, 150 cases in each one. In the acupuncture group, according to the different types of cervical spondylosis, acupuncture was applied at three lines of cervical Jiaji (EX-B 2), once a day. In the medication group, jingfukang granules were prescribed for oral administration, one bag each time, three times a day. The treatment of ten days made one session in the two groups and two sessions were required totally. Before and after two sessions of treatment, the clinical assessment scale for cervical spondylosis (CASCS) was adopted to evaluate the score of subjective symptoms, clinical physical signs and adaptability as well as the total score in the patients of the two groups and the efficacy was compared.

RESULTSThe patients' symptoms and physical signs were alleviated, the adaptability was improved and the score of each item and the total score were increased in the two groups after treatment (all P<0.01). The improvements in the acupuncture group were better than those in the medication group (all P<0.01). The curative and markedly effective rate was 90.7% (136/150) in the acupuncture group, better than 66.0% (99/150) in the medication group (P<0.01).

CONCLUSIONAcupuncture at three lines of cervical Jiaji (EX-B 2) achieves the significant clinical efficacy on cervical spondylosis. This therapy is superior to relieving symptoms and physical signs and recovering adaptability as compared with jingfukang granules.

OBJECTIVETo observe the effect of Kanglaite injection(KLT) on the proliferation and telomerase activity of mesangial cells in rats.

METHODMTT, telomere repeat amplification protocal (TRAP), ELISA, PAGE and silver-stain were applied to detect the growth rate and telomerase activity of MC after stimulation of KLT and IL-1.

RESULTThe growth rate of MC was enhanced by IL-1 stimulation, which was accompanied with a redection of the activity of telomerase. Adversely, the growth rate of MC was reduced by KLT, which was accompanied with an enhancement of activity of telomerase. Moreover, the growth rate of MC and the activity of telomerase were both inhibited by the combinative use of IL-1 and KLT without any influence from the sequence of their administration.

CONCLUSIONKLT could inhibit proliferation and telomerase activity of MC with or without pre-stimulation with IL-1. KLT might be useful to prevent and treat glomerular nephritis related to MC proliferation.
