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 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.

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.

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.

OBJECTIVETo investigate the risk factors for asthma in children in Hefei, China and to provide a strategy for asthma control in this region.

METHODSA total of 400 children with a confirmed diagnosis of asthma, as well as 400 children of comparable age, sex, living environment, and family background, who had no respiratory diseases, were selected for a case-control study. A survey questionnaire survey was completed for all children. The obtained data were subjected to univariate and multivariate logistic regression analysis to determine the risk factors for asthma.

RESULTSThe logistic regression analysis showed that a family history of allergy, allergic rhinitis, infantile eczema, no breastfeeding, air-conditioning and passive smoking were the risk factors for asthma in children, with odds ratios of 9.63, 7.56, 4.58, 2.16, 1.73, and 1.55 respectively.

CONCLUSIONSIn order to reduce the incidence of asthma, we should advocate breast feeding, promote outdoor activities, keep ventilation natural, prevent passive smoking and cure allergic rhinitis.

OBJECTIVETo investigate the cumulative prevalence rate, distribution characteristics, epidemic seasons, predisposing factors and current treatment situation of childhood asthma in Hefei City, China.

METHODSIn the investigation, stratified cluster random sampling as well as centralized access and separate home visits were applied, and primary screening forms were filled out. Further confirmation was sought in the primary positive cases, according to the diagnostic criteria for asthma. Statistical analysis was performed to determine the cumulative prevalence rate, current treatment situation and predisposing factors for childhood asthma as well as the distribution characteristics of asthma in children of different ages and sexes.

RESULTSThe cumulative prevalence rate of childhood asthma was 5.92%, and there was no significant difference between males and females (6.33% vs 5.42%; P>0.05). The cumulative prevalence rate was highest (8.25%) in children aged 3-6 years. Of the children with acute asthma attack, 42.0% suffered attacks during periods of seasonal transition, and 34.4% suffered attacks at midnight. Among the 552 children with a confirmed diagnosis of asthma, 533 (96.6%) developed asthma due to respiratory tract infection and 312 (56.5%) due to weather change. Most asthmatic children (513/552, 92.9%) received treatment with antibiotics, and 492 asthmatic children (89.1%) were treated with systemic hormones.

CONCLUSIONSThe cumulative prevalence rate of childhood asthma is 5.92% in Hefei, and the peak age of onset is 3-6 years. Acute asthma attack occurs mostly during periods of seasonal transition and at midnight. Respiratory tract infection and weather change are the main predisposing factors for childhood asthma. Antibiotics and systemic hormones are still widely used in the treatment of asthma.
