Objective To observe the effects of transcutaneous electrical acupoint stimulation (TEAS) on hand dysfunction after stroke. Methods From March, 2013 to June, 2015, 56 cases of stroke with hand dysfunction were divided into group A (n=28) and group B (n=28). Both groups received basic rehabilitation, while group B received TEAS in addition, for six weeks. They were evaluated with Brunnstrom Grades, Manunl Muscle Test (MMT), Fugl- Meyer Assessment (FMA) of fingers, Motor Status Scale (MSS), modified Ashworth Scale (MAS), National Institutes of Health Stroke Scale (NIHSS), Motor Hand Functional Status Score and Barthel Index (BI). Results The scores of FMA of fingers, MMT of wrist flexion, MSS, MAS and BI were more in group B than in group A (t>2.2527, P<0.05), and the score of NI-HSS was less in group B (t=3.556, P<0.001). There was no significant difference between two groups in the score of Motor Hand Functional Status Score and MMT of wrist extension (t<0.310, P>0.05). Conclusion TEAS can promote the recovery of hand function and the activi-ties of daily living in patients after stroke.

Objective To evaluate the imaging performance and characteristics of peripheral primitive neuroectodermal tumors (pPNET), in order to raise awareness of the disease and the diagnostic accuracy. Methods Thirteen patients with pPNET who confirmed by puncture or pathology were enrolled in this study. The CT and MRI features were retrospectively analyzed. Four patients received simple routine CT examination, and 9 patients had MRI examination based on X-ray, CT examination. Results The part of body involved was more widely.Two patients occurred in the sinuses, 1 patient in the chest wall, 1 patient in the lung, and 3 patients in the abdominal and pelvic(1 patient involved the pelvic floor through the pelvic wall lesions to basins), 1 patient in the spine, and 5 patients located in the extremities. The characteristics of pPNET by CT and MRI in soft tissue of 8 patients showed single large soft tissue mass, and the biggest was 11.2 cm × 10.6 cm. In bonds and joints of 5 patients, CT and MRI showed wide range of soft tissue mass, mixed internal signal/density with obviously uneven enhancement, significant bone destruction and dissolvable osseous changes, and no obvious tumor bone and calcification. Conclusions Each site has its relative imaging characteristics of pPNET. CT and MRI can show lesions involving the scope, internal structure, with or without adjacent tissue invasion and metastasis, and provide guidance for clinical treatment and selecting treatment regimen. But in the end, it depends on the diagnosis of pathological and immunohistochemical examination.

Objective To study the changes of flow parameters of superior mesenteric artery (SMA) in children with abdominal type Henoch-Schonlein purpura (HSP) using color Doppler ultrasound.Methods Ten children with abdominal type HSP and 17 controls were included in present study.The blood flow parameters of SMA[including peak velocity(PV),end-diastole velocity(EDV),resistant index(RI)]were measured at acute and recovery stage separately.Statistical analysis was conducted among groups.Results PV were (41.57±8.02)cm/s,(33.38±7.44)cm/s and (35.34±9.73)cm/s in acute stage,recovery stage and control group,respectively.There was no statistically significant difference among groups(F=2.471,P=0.10).EDV were(7.63±4.28)cm/s,(4.23±2.57)cm/s and (3.77±0.87) cm/s in acute stage,recovery stage and control group,respectively.There was significantly significant differences between acute stage group and other two groups(t=0.066,P=0.025;t=0.059,P=0.003).RI were (0.85±0.17),(1.00±0.15) and (1.04±0.13) in acute stage,recovery stage and control group,respectively.Also there was significantly significant differences between acute stage group and other two groups(t=1.391,P=0.020;t=1.239,P=0.026).Conclusion For abdominal type HSP in children,the changes of PV,EDV and RI of SMA were significant,which may help us determine the stage of disease.

Objective To summarize the characteristics of fetal hand deformity in prenatal two-and three-dimensional u1trasonography. To analyze the causes of missed diagnosis of prenatal u1trasonography in detecting fetal hand deformity. Methods Systematic continuous sequence approach was performed with two-and three-dimensional u1trasonography in 11 854 cases to detect the fetal hand development, deformity and accompanied malformations. Prenatal sonographic features of fetal hand deformities (59 cases) were correlated with the morphology and X-ray characteristics of the delivered fetuses. Results Fifty-nine cases of fetal hand deformity were diagnosed out of 11 854 fetuses by prenatal u1trasonography:44 cases of abnormal wrist posture,1 case of full-ifnger absence, 2 cases of metacarpal and phalanx absence, 3 cases of clinodactyly, 2 cases of forearm and hand absence, 1 case of syndacty, 1 case of polydacty, 5 cases of lethal bone dysplasia. The detection rate was 0.50%(59/11 854). Eight cases were missed:3 cases of partial ifnger absence, 2 cases of clinodactyly, 1 case of syndacty, and 2 cases of polydacty. The rate of missed diagnosis is 11.90%(8/67). Abnormal wrist posture showed a hook-shaped hand in the wrist. Full-finger absence showed that one or multiple ifngers were absent. Metacarpal and phalanx absence showed no fetal hands. Clinodactyly showed that four ifngers were not in the same plane. Forearm and hand missing showed that ulna, metacarpal and phalangeal were absent. Syndacty showed a beak-like hand. Multi-ifnger indicated six ifngers in one hand. Lethal bone dysplasia showed very short limbs. Conclusions Prenatal u1trasonography played an important role in detecting and diagnosing severe type of fetal hand deformity. The detection rate of fetal hand deformities can be greatly improved by appropriate use of the scan-time, fetal position, systematic continuous sequence approach and real three-dimensional u1trasonography.

OBJECTIVETo verify the electric synchronism, mechanic synchronism and hemodynamics of selective site pacing.

METHODSPacing in the right ventricular cardiac apex (RVA), the right ventricular His bundle region (His), and the septum of right ventricular high-positioned outflow tract (RVOT), CO and CI were recorded. The electrical synchronism was assessed by observing the width and shape in a 12-lead surface ECG. The mechanical synchronism was estimated by using the VVI (vector velocity imaging) technology of the Acuson Sequia 512.

RESULTSThe results showed that CO and CI were lower while pacing in RVA, but they were not significant different (P>0.05). The QRS width: (124 +/- 5.3) ms while pacing in His, (144 +/- 7.1) ms while pacing in RVOT and (156 +/- 8.6) ms while pacing in RVA. The QRS width while pacing in His and in RVOT were narrower than in RVA and there were significant differences (P<0.01). Vector velocity imaging showed that mechanical synchronism was better while pacing in RVOT than that in RVA.

CONCLUSIONPacing in RVOT seems better than pacing in traditional RVA, and the operation was no more difficult than the traditional operation.

OBJECTIVETo investigate the effect of corticosterone on the expression of the neuronal migration protein lissencephaly 1 (LIS1) in developing cerebral cortical neurons of fetal rats.

METHODSThe primary cultured cerebral cortical neurons of fetal Wistar rats were divided into control group, low-dose group, and high-dose group. The neurons were exposed to the medium containing different concentrations of corticosterone (0 μmol/L for the control group, 0.1 μmol/L for the low-dose group, and 1.0 μmol/L for the high-dose group). The neurons were collected at 1, 4, and 7 days after intervention. Western blot and immunocytochemical staining were used to observe the change in LIS1 expression in neurons.

RESULTSWestern blot showed that at 7 days after intervention, the low- and high-dose groups had significantly higher expression of LIS1 in the cytoplasm and nucleus of cerebral cortical neurons than the control group (P<0.05), and the high-dose group had significantly lower expression of LIS1 in the cytoplasm of cerebral cortical neurons than the low-dose group (P<0.05). Immunocytochemical staining showed that at 1, 4, and 7 days after corticosterone intervention, the high-dose group had a significantly lower mean optical density of LIS1 than the control group and the low-dose group (P<0.05). At 7 days after intervention, the low-dose group had a significantly lower mean optical density of LIS1 than the control group (P<0.05).

CONCLUSIONSCorticosterone downregulates the expression of the neuronal migration protein LIS1 in developing cerebral cortical neurons of fetal rats cultured in vitro, and such effect depends on the concentration of corticosterone and duration of corticosterone intervention.

OBJECTIVETo evaluate the clinical studies of acupuncture for treatment of depressive neurosis, collect the high quality evidence relative to clinical acupuncture practice for clinical decision-making reference.

METHODSAround crucial common questions of acupuncture clinical practice, the documents of clinical study were comprehensively retrieved. According to 5-grade criterion of evidence-based medicine, the evidence from high to low level were selected to answer corresponding clincal questions and RevMan 5.0.20 was used to analyze the final indicator.

RESULTSNineteen documents of clinical study accord with the inclusive criterion were retrieved. Level-A evidence showed effectiveness of acupuncture. Acupuncture might be superior or equal to fluoxetine, with little adverse effect and high safety. Level-C evidence showed acupuncture might be superior or equal to Amitriptyline, with little adverse effect and high safety. And no relative clinicial evidence compared effect of acupuncture with that of psychotherapy or behavior therapy. Only one level-C evidence showed there was no effect difference between acupuncture combined with bloodletting therapy and bloodletting alone. Two level-C evidence showed the effect of acupuncture combined with western medicine was superior to that of medicine alone, eg. catgut embedding therapy combined with Fluoxetine, electroacupuncture combined with Seroxat.

CONCLUSIONAcupuncture for depressive nerosis has a positive effect. Acupuncture has an equal effect compared with western medicine, while strictly designed equivalent and non-inferior studies are demanded. The effect of acupuncture combined with medicine has some advantage, but need high quality studies to verify.

UNLABELLEDOBJECTIVE : To study the anti-atherosclerotic mechanism of bear bile powder (BBP) in Shexiang Tongxin Dripping Pill (STDP) , and to provide scientific evidence for treating atherosclerosis (AS) by its therapeutic characteristics of cool resuscitation.

METHODSAS model was duplicated using ApoE-/- gene knocked mice fed with high-fat diet. Thirty ApoE-/- deficient male mice were divided into four groups according to body weight using random digit table, i.e., the model group (A, n =9), the STDP group (B, n=E7), the STDP without BBP group (C, n =7), and the BBP group (D, n =9). Besides, another 9 C57BL/6J male mice of the same age were recruited as a normal control group (E). All mice in Group B, C, and D were respectively administered with corresponding drugs (30, 30, and 0. 33 mg/kg) by gastrogavage. Equal volume of normal saline was administered to mice in Group A and E. All medication lasted for 8 successive weeks. Serum levels of inflammatory cytokines such as interleukin 2 (IL-2), interleukin 6 (IL-6), tumor necrosis factor a (TNF-α), interferon y (IFNγ), and oxidized low-density lipoprotein (ox-LDL) were measured by ELISA. Serum levels of malondialdehyde (MDA), activities of glutathione (GSH) and superoxide dismutase (SOD) were determined using biochemical assay. Contents of reactive oxygen species (ROS) in the aortic root was detected by dihydroethidum (DHE) fluorescent probe. Expression levels of microRNAs (such as miR-20, miR-21, miR-126, and miR-155) were detected by real-time PCR.

RESULTSThe fluorescence intensity of the aorta was obviously enhanced in Group A. But it was obviously attenuated in Group B, C, and D, and the attenuation was the most in Group B. Compared with Group E, serum levels of IL-2, IL-6, TNF-α, IFN-γ, oxLDL, and MDA all increased (P <0. 01), GSH contents and SOD activities decreased (P <0. 01), expression levels of miR-126, miR-21, and miR-155 in aorta increased (P <0. 01), and the expression level of miR-20 decreased in Group A (P<0. 01). Compared with Group A, serum levels of IL-2, IL-6, TNF-α, IFN-γ, oxLDL, and MDA were all down-regulated (P <0. 01), GSH contents and SOD activities were up-regulated (P <0. 01), expression levels of miR-126, miR-21, and miR-155 in aorta were down-regulated in Group B, C, and D (P <0. 01). The expression level of miR20 was up-regulated in Group B and D (P <0. 01). Compared with Group B, serum levels of IL-2, IL-6, TNF-α, IFN-γ increased (P <0.01); GSH contents and SOD activities decreased, levels of MDA and oxLDL increased (P <0. 01) in Group C and D. Expression levels of miR-20 and miR-155 were down-regulated in Group C and D (P <0. 01).

CONCLUSIONSSTDP played roles in significantly regulating inflammatory factors and oxidative stress factors. Its mechanism might be possibly associated with regulating expressions of miR-126, miR-21, miR-155, and miR-20 in aorta. BBP played significant roles in STDP.

OBJECTIVEPericardial effusion (PE) is a major complication of atrial fibrillation ablation (AFB). We analyzed the incidence, risk factors and managements of PE post AFB (radiofrequency catheter ablation).

METHODSA total of 156 consecutive patients with AF [male 108, paroxysmal AF 114, (57.6 +/- 11.3) years], who underwent AFB guided by a three-dimensional mapping system (CARTO or CARTO-Merge, Biosense-Webster Inc., Diamond Bar, California) and a circular mapping catheter (Lasso, Biosense-Webster Inc., Diamond Bar, California), were included in this study. The ablation strategy included circumferential pulmonary veins isolation (CPVI), linear ablation and/or complex fractionated atrial electrograms (CFAEs) ablation. Electrophysiological data and vital signs of patients were recorded by a multiple physiological recorder (Prucka, GE Medical Systems) during ablation. Ablation process, sites, duration and other related factors were also recorded. Echocardiography and other examinations were performed for diagnosing and monitoring PE.

RESULTSCPVI were achieved in all 156 patients. Incidence of PE was 10.3% (16/156) post AFB. One patient developed acute cardiac tamponade and emergency drainage of the pericardial effusion was performed through a median sternotomy and patient recovered without complications during the 18 months follow-up. The rest 15 PE patients with small PE received outpatient care and no invasive treatment was needed and PE disappeared after 3 months in 6 patients and after 6 months in 9 patients. Univariate analysis showed that the composition of gender (P < 0.01), ablation in coronary sinus (CS, P = 0.026), ablation of CFAEs (P = 0.037) and superior vena cava (SVC, P = 0.041) were risk factors for PE. Logistic regression analysis showed that female gender [beta = 3.594, exp (b) = 36.4, 95% confidence interval (CI): 4.2 - 312.1, P = 0.001] and ablation in CS [beta = 2.419, exp (b) = 11.2, 95% CI: 1.0 - 124.6, P = 0.049] were independent risk factors for PE post AFB.

CONCLUSIONSPE is a common complication of AFB, female gender and ablation in CS were independent risk factors for PE. Most PE patients experienced spontaneous recovery but emergency treatment was needed for patient with cardiac tamponade.
