OBJECTIVETo observe improved effects of Jingjin acupuncture on fine activity of hemiplegic hand in recovery period of stroke.
METHODSFifty cases were randomly divided into an observation group and a control group, 25 cases in each one. Regular western medicine treatment, rehabilitation training and regular acupuncture (in which Shuigou (GV 26), Baihui (GV 20), Neiguan (PC 6), etc. were selected) were applied in both groups. Additionally, muscles in palm side of affected hand, dorsal metacarpophalangeal joints and proximal interphalangeal joints were treated with acupuncture in the observation group, once every other day and electroacupuncture was applied when arrival of qi was acquired. Baxie (EX-UE 9) in the affected hand were needled in the control group, and electroacupuncture was added when arrival of qi was acquired. Ten days of treatment was considered a treatment course, and after two courses Lindmark score, Brunnstrom movement function grade, joint range of hand and Barthel index (BI) were observed in two groups.
RESULTSCompared before the treatment, the Lindmark score in two groups were both improved after the treatment (both P < 0.01). Compared with the control group, the motor coordination ability, sensory function and total score of Lindmark in observation group were obviously improved (differences before and after treatment: 8.24 +/- 3.07 vs 6.84 +/- 2.43, 3.52 +/- 2.33 vs 2.16 +/- 2.12, 11.76 +/- 3.55 vs 9.00 +/- 3.62, all P < 0.05). The Brunnstrom movement function grade was significantly improved in both groups after treatment (both P < 0.01), which was more obvious in the observation group (P < 0.05). The joint range of hemiplegic hand was improved in both groups after treatment (both P < 0.01), which was more obvious in the observation group [differences before and after treatment: (25.35 +/- 10.91) degrees vs (18.65 +/- 7.86) degrees, p < 0.05]. The score of BI was also significantly improved after treatment in two groups (both P < 0.01).
CONCLUSIONThe Jingjin acupuncture could effectively improve fine activity of hemiplegic hand in recovery period of stroke prove daily life ability.

Objective To clarify the role of FLT3 signaling-dependent pulmonary conventional dendritic cells (cDCs) in the pathogenesis of lipopolysaccharide (LPS)-induced acute lung injury (ALI),and as well as the modulation effects of cDCs in vivo on the inflammatory responses to acute lung injury.Methods Thirty C57BL/6 male mice were divided into normal control group,LPS group,FLT3L pretreatment group,lestaurtinib,(a high efficient and specific blocker in FLT3 signal pathway) pretreatment group and vehicle (DMSD) control group.FLT3L and lestaurtinib were administrated subcutaneously for 5 days.Murine model of ALI was subsequently established by intra-tracheal application of LPS and lung specimens were harvested 6 h or 24 h later.The accumulation and maturation of pulmonary cDCs were assessed by flow cytometry.IL-6 and TNF-α were quantified to evaluate lung inflammation.Lung injury was estimated by lung wet weight/body weight ratio (LWW/BW) and histopathological assessment.Lung myeloperoxidase (MPO) activity was measured to evaluate neutrophil infiltration.Transcription factors Tbet/GATA-3 mRNA ratio was determined to estimate balance of Th1/Th2 response.IFN-γ and IL-4 were quantified to evaluate Th1-specific and Th2-specific cytokine production respectively.Results The accumulation and maturation of pulmonary cDCs peaked at 6h after LPS challenge.FLT3L pretreatment significantly stimulated the accumulation and maturation of pulmonary cDCs (P < 0.05),leading to markedly deterioration of LWW/BW and lung histopathological changes.Meanwhile lung MPO activity and T-bet/GATA-3 mRNA ratio were elevated (P < 0.05).Furthermore,the production of IL-6,TNF-α and IFN-γwas markedly increased by FLT3L pretreatment (P < 0.05).In contrast,lestaurtinib pretreatment markedly inhibited the accumulation and maturation of pulmonary cDCs (P < 0.05),leading to significant improvement of LWW/BW and lung histopathological changes.Meanwhile lung MPO activity and T-bet/ GATA-3 mRNA ratio were decreased (P < 0.05).Furthermore lestaurtinib efficiently suppressed the production of IL-6,TNF-α and IFN-γ (P < 0.05).Conclusion This study thus demonstrated that FLT3 signaling-dependent pulmonary cDCs could control the initiation of acute lung inflammation response to LPS-induced ALI through the regulation of neutrophil infiltration and balance of Thl/Th2 response.

To realize the accurate positioning and quantitative volume measurement of tumor in head and neck tumor CT images, we proposed a level set method based on augmented gradient. With the introduction of gradient information in the edge indicator function, our proposed level set model is adaptive to different intensity variation, and achieves accurate tumor segmentation. The segmentation result has been used to calculate tumor volume. In large volume tumor segmentation, the proposed level set method can reduce manual intervention and enhance the segmentation accuracy. Tumor volume calculation results are close to the gold standard. From the experiment results, the augmented gradient based level set method has achieved accurate head and neck tumor segmentation. It can provide useful information to computer aided diagnosis.

Objective: To explore the relationship between plasma levels of calcitonin gene related peptide (CGRP) and cardiac function in ventricular septal defect (VSD) children before and after the interventional therapy.
Methods: Our research included 2 groups:VSD group, n=90 containing 43 male and 47 female at the age of (3-12) years and treated in our hospital from 2011-09 to 2012-09, Control group, n=50 healthy children with matched age and gender. The levels CGRP were measured at before and 24 hours, 3 days, 5 days, 3 months after the therapy. The cardiac function as left ventricle end-diastolic diameter (LVEDD), left ventricle end systolic diameter (LVESD), left ventricle end diastolic volume (LVEDV), left ventricle end systolic volume (LVESV) and ejection fraction (EF) were examined by echocardiography at before and after the procedure.
Results: Before interventional procedure, the level of CGRP in VSD group was lower than Control group (35.28 ± 7.25) pg/ml vs (50.90 ± 8.60) pg/ml, t=11.42, P<0.01. In VSD group, the post-procedural levels of CGRP were increased at all time points, the highest level was at 24 hours and the descending started at 3 days after procedure;the levels of CGRP at before and 24 hours, 3 days, 5 days after the procedure were different as (35.28 ± 7.25) pg/ml vs (102.03 ± 11.73) pg/ml, (35.28 ± 7.25) pg/ml vs (93.36 ± 9.12) pg/ml, (35.28 ± 7.25) pg/ml vs (87.91 ± 8.54) pg/ml, t=27.03, 26.93, 24.51, all P<0.01. In VSD group, the LVEDD, LVESD, LVEDV and LVESV decreased gradually at 5 days, 3 months and 6 months after the procedure;the levels of CGRP were signiifcantly related to LVEDD, LVESD, LVEDV, LVESV at before and 5 days, 3 months after the procedure, all P<0.05.
Conclusion: Plasma levels of CGRP closely related to ventricular cavity diameter, which was important for evaluating the cardiac function in VSD children after the interventional therapy.
