Objective To explore the effects of wearing ankle-foot orthoses (AFOs) on motor function in children with spastic cerebral palsy (SCP). Methods Fifty-two children with SCP were randomly divided into a wearing-for-training group (n = 16, group 1 ), a day-wearing group (n = 19, group 2) and a day-night-wearing group (n = 17, group 3). In addition to the conventional rehabilitative treatment given to all participants, the children in group 1 wore AFOs during movement training, and children in group 2 wore AFOs in the daytime for 6-8 h per day, while AFOs were applied to the children in group 3 for 24 hours a day except for cleaning and during certain training routines. All the treatments were continued for 2 months. Clinical assessments included the range of passive ankle dorsi-and plantarflexion (APROM) , modified Ashworth scale (MAS) ratings, and the D and E dimensions of the Gross Motor Function Measure (GMFM). All were performed before and after treatment. Results Before treat-ment, no statistically significant differences were found among the three groups in terms of APROM, MAS, or GM-FM. There were significant subsequent improvements in groups 2 and 3 when compared with group 1 in terms of APROM, MAS and GMFM results. Group 2's improvements in APROM and MAS results were not significantly better than those of group 3, but their average GMFM score improvements were significantly better. Conclusion Wearing AFOs in the daytime 6-8 hours per day is more effective in reducing spasticity and improving functional performance in children with SCP.

Objective To provide clinical evidence for the optimal acupuncture time in acupuncture treatment of hearing disorder in kids with cerebral palsy.Method Ninety eligible patients were randomized into 3 groups, 30 in each group. Group A was treated for 30 min, group B for 45 min, and group C for 1 h. The hearing improvement was evaluated by using brain-stem auditory evoked potential (BAEP).Result The detection of BAEP showed that the latent and peak periods of wave I,Ⅲ, and V were significantly shortened in the 3 groups after intervention (P<0.01), suggesting that acupuncture can produce a marked efficacy in treating hearing disorder in cerebral palsy. The inter-group comparisons showed that the efficacy of group A was significantly higher than that of group B and C (P<0.05); there was no significant difference in comparing the efficacy between group B and C (P>0.05). It’s indicated that the optimal acupuncture time span should be 30 min.Conclusion With the same acupuncture skills, acupuncture for 30 min can produce a comparatively higher efficacy in treating infantile hearing disorder.

Objective To investigate the duration for silicon gastric tube to indwell in stomach of aged patients.Methods One hundred elderly patients needing long-term nutrition support were equally randomized into two groups: control group and observation group.The former had the gastric tubes indwelled in the stomach for 4 weeks and the latter for 3 weeks.The two groups were compared about the used tubes in terms of the color of tube at the length of the first 10cm,the indentation by reflection for 10 seconds at the tube of first 10 cm,the hardness of the tube at the length of the first 10 cm and the springback angle of tube at the first 10cm after reflection.Results The tubes in the observation group were significantly better than those in the control group in terms of color,indentation,hardness and springback angle(all P<0?01).Conclusion The duration of indwelling silicon gastric tubes in stomach can be three weeks for old patients needing long-term nutrition support via indwelling silicon tubes in their stomach.

Objective: To seek a treatment that can improve the effect on dysphagia following post-stroke pseudobulbar palsy. Methods: Sixty patients were randomly allocated into observation and control groups, 30 cases each. The observation group was treated with Western drugs plus acupuncture at Tiantu (CV 22) and other three acupoints around Lianquan (CV 23) and the control group with simple Western drugs. Results: The effective rate was 86.7% in the observation group and 30.0% in the control group. Conclusion: Acupuncture can improve the curative effect of Western drugs on dysphagia following post-stroke pseudobulbar palsy.

Objective To observe the effect of meridian balancing on speech disorder in children with cerebral palsy. Methods 130 childrenaged 1.5~7 years old were divided into the control group (n=62) and treatment group (n=68). The control group received routine rehabilitationwhile the treatment group received meridian balancing in addition. Results The rate of improvement was 89.7% in treatmentgroup and 79% in control group (P<0.05). The rate was more for those with language retardation than with anarthria in the treatment group(P<0.01). Conclusion The meridian balancing is effective on speech disorder in children with cerebral palsy, especially for those with languageretardation.

Objective To investigate the influence of gestational vitamin A(VA) deficiency on lipid synthesis in offspring liver tissue by using the rat model of gestational vitamin A deficiency.Methods The rat model of gestational VA deficiency was established and divided into the normal AV,VA deficiency and VA deficiency and supplement (VAD) groups.The offspring blood lipid levels were detected.The mRNA expression changes of lipid synthesis molecule ACC1,FAS and SREBP1 in liver were detected;the lipid droplet deposition situation after HE staining in offspring liver tissue section was observed.Results The HDL-C level of the VAD group was significantly lower than that of the VA normal group(VAN group and VAS group,P＜0.05),and the difference between the VAN group and VAS group had no statistical difference(P＞0.05).The TG level had statistically significant difference among the three groups(P＜0.05).The ACC1,FAS and SREBP1 mRNA expression levels in the VAD group were significantly increased.The liver in the VAD group appeared more lipid droplet deposit with partial lipid droplet vacuoles in cytoplasm;while the liver cells in the VAS and VAN groups showed the regular arrangement without obvious lipid droplet deposit.Conclusion Gestational VA deficiency may induce the abnormal activation of liver lipid synthesis pathway in rat offspring and causes lipid metabolic disturbance.

ObjectiveTo evaluate the role of galactomannan (GM) detection in bronchoalveolar lavage fluid (BALF) in the diagnosis of invasive pulmonary aspergillosis (IPA) in elderly patients with lung diseases.MethodsThe elderly patients with lung diseases and suspected of having IPA were enrolled. BALF for culture and GM detection, and serum samples for GM detection were obtained from all participants.According to European Organization for Research and Treatment of Cancer/Mycoses Study Group (EORTC/MSG) with host factors, clinical criteria, mycological evidence and histological or cytopathological evidence, all patients were categorized into the proven, probable,possible and no IPA patients. The IPA patients were considered as IPA group while no IPA was considered as control group. ResultsAmong 76 enrolled elderly patients, 18 cases were diagnosed with IPA (1 proven, 11 probable and 6 possible), the remained 58 patients were as control group.Based on a GM index cutoff value of ≥0. 5, the sensitivity, specificity, positive predictive value and negative predictive value for BALF were 83.3％, 82. 8％, 60.0％ and 94.1％, respectively; these variables in serum were 55.60％ , 91.4 ％, 66.7 ％ and 86.9％ , respectively. Using a GM index cutoff value of ≥1.0, the specificity and positive predictive value of both BALF GM and serum GM reached 100％, but the sensitivity and negative predictive value of BALF GM were higher than serum GM (66.7％ vs. 22.2％, 90.60％ vs. 80.60％, respectively). Receiver operating characteristic curve analysis yielded a sensitivity of 83.4％ and a specificity of 96.6％ at a BALF GM index cutoff value of ≥0.725. ConclusionsGM detection in BALF seems to be a useful tool in the diagnosis of IPA in elderly patients with lung diseases,and could be widely used in future.

Aim To identify alteration in key molecular components related to memory formation and insulin signaling in the hippocampus after rosiglitazone was in-jected into the ob/ob mice to test whether cognitive dysfunction was pharmacologically reversed by regula-tion of rosiglitazone. Methods The age-matched mice were divided into three groups ( n=18 ): Saline-trea-ted WT mice ( WT-Saline);Saline-treated ob/ob mice ( ob/ob-Saline) and RSG-treated ob/ob mice ( ob/ob-RSG) through intraperitoneal injection of rosiglitazone ( RSG) . The random glucose levels were measured for 10 days during the intraperitoneal injection period. No-vel object recognition was performed before mice were sacrificed. Western blot was implemented to evaluate the following proteins: BACE1, p-Tau, p-IRS1,IRS1, p-Akt and Akt in hippocampal tissues. The Aβ1-40 levels were detected by ELISA Kit. Results The random blood glucose levels were significantly re-duced in ob/ob-RSG compared with ob/ob-saline. RSG treatment led to an increase in hippocampus-de-pendent cognition of ob/ob mice according to the novel object recognition. The proteins levels of BACE1, p-Tau and Aβ were lowered in RSG-treated ob/ob mice. Furthermore, RSG treatment up-regulated hippocampal p-IRS1/IRS1 and p-Akt/Akt ratio. Conclusion Ros-iglitazone ameliorates cognitive deficits in ob/ob mice through up-regulating insulin signaling pathways in the hippocampus.
