Objective To analyze the effect of both limited selective posterior rhizotomy(LSPR)and limited selective soft tissue release(LSTR)on healing motor function related to spasmo-cerebral palsy in both legs.Methods Thirty-eight cases CP with LSPR and LSTR were collected in the past 3 years;21 males,17 females;aged 3.0-8.11 years old,on the average of 5.11 years old.Perioperative motor function were evaluated according to motor function scores.Results LSPR and LSTR played a role in improving motor function obviously,and had little difference in orthomorphia after SPR for 6 months.Conclusion LSPR and LSTR may improve cramp and abnormality in both legs,and enhance motor function,so the secondary operation agony can be avoided,and the family economic burden relived.

Objective To explore the relation between the level of oxygen pressure and lactate in arterial blood and prognosis of cardiopulmonary resuscitation (CPR).Methods 36 patients with sudden cardiac arrest received CPR were selected.Patients were divided into 3 groups.The 21 patients who 30 minutes of CPR didn't regain heart beats were group A,those 10 who kept blood circulation for over 2 hours but finally died were group B,and the remaining 5 who survived were group C.Control group was made up of 20 people with no disease.In CPR immediately (0h),1h,3h,6h,12h were measured in blood specimens from arterial partial pressure of oxygen and lactate levels were compared among groups of patients dynamic changes of the index.Results The 3 groups A,B,C significantly reduced blood oxygen pressure,blood lactate increased significantly the CPR in the early,and compared with the control group there was significant difference( P ＜ 0.01 ).The group B CPR 3h,6h,and continue until no significant changes in 12h;The group C CPR 3h,6h began to increase blood oxygen pressure and blood lactate levels begin to decline,blood oxygen pressure increased significantly,lower blood lactate to a lower level after 12h.Taken with marked changes in B group,the difference was significant ( P ＜ 0.05 ).Conclusion Arterial partial pressure of oxygen and blood lactate levels could be used as indicators of prognosis of patients with CPR.Sustained increase in arterial oxygen partial pressure showed a good prognosis,lactate levels continued to rise that a poor prognosis.

OBJECTIVE:To study the effects of rosiglitazone(RH)on body weight,FPG,FFA and other indicators in diabe-tes model rabbit. METHODS:18 rabbits were evenly randomized into control group,model group and dextran group. The latter 2 groups were given alloxan intravenously to induce diabetes model. 3 groups were given RH(0.5 mg/kg)intragastrically,and dex-tran group was additionally given dextran 40 glucose injection(5 ml/kg)intravenously,once a day,for consecutive 3 weeks. Body weight,serum level of FPG,FFA,AngⅡ and NO were determined before and after medication. RESULTS:Compared with be-fore medication,body weight of rabbits in control group were increased after medication,while the levels of FFA and AngⅡ were decreased;the levels of FPG and FFA were decreased in model group;body weight of rabbits were decreased in dextran group af-ter medication,with statistical significance (P<0.01 or P<0.05);other indicators had no statistically significant difference (P>0.05). The level of FFA in dextran group was higher than in model group after medication,with statistical significance(P<0.01). CONCLUSIONS:Rosiglitazone can lead to weight gain by a mechanism which reduce the level of FFA.

ObjectiveTo evaluate the association between Pro12Ala polymorphism in peroxisome proliferator activated receptorγ2 (PPARγ2) gene and gestational diabetes mellitus(GDM).Methods Publications on genetic association studies of PPARγ2 and GDM were searched using the PubMed database, The HuGE Navigator, China National Knowledge Infrastructure (CNKI), Wanfang database and VIP Science from the inception of the databases to December 1, 2014. Two reviewers independently selected literature according to the inclusion and exclusion criteria, extracted data and assessed the quality of the data using the Newcastle-Ottawa Scale (NOS) standard. Meta-analysis was performed using RevMan 5.3 software.ResultsOverall, 13 eligible articles were identified, including seven in English and six in Chinese, with a total of 2 787 GDM cases and 5 408 healthy controls. Quality assessment showed that the quality of the 13 articles was all good, with NOS≥5. (1) Pro12Ala polymorphism in PPARγ2 (allele Ala or genotype Ala/Ala or Pro/Ala) was shown to be highly associated with GDM occurrence on general evaluation, with anOR(95%CI) of 0.74(0.60-0.93) in the allele model and 0.79(0.65-0.96) in the dominant genetic model (P<0.05, respectively). (2) Pro12Ala polymorphism in PPARγ2 was shown to be highly associated with GDM occurrence in Asians in a stratification analysis of ethnicity in the populations included in the studies, with anOR(95%CI) of 0.61(0.48-0.79) in the allele model and 0.64(0.50-0.82) in the dominant genetic model (P<0.01, respectively). No correlation was found between the Pro12Ala polymorphism in PPARγ2 and GDM in the Caucasian population. (3) A meta-analysis of six Chinese studies showed that the Pro12Ala polymorphism in PPARγ2 was associated with the risk of GDM in the Chinese population, with anOR(95%CI) of 0.52 (0.36-0.73) in the allele model and 0.55(0.39-0.80) in the dominant genetic model (P<0.01, respectively). (4) No significant association was observed in the TaqMan allelic discrimination assay with anOR(95%CI) of 0.96(0.83-1.10) in the allele model and 0.95(0.81-1.11) in the dominant genetic model (P>0.05, respectively), although there was still a significant correlation in polymerase chain reaction-restriction fragment length polymorphism with anOR(95%CI) of 0.58(0.43-0.79) in the allele model and 0.62(0.45-0.85) in the dominant genetic model (P<0.01, respectively).ConclusionsThe Ala allele and the Ala/Ala or Pro/Ala genotypes of the Pro12Ala polymorphism in PPARγ2 can decrease the risk of GDM. However, there are differences in the results which are affected by the genotype analysis method or races.

Objective To observe senile plaque and iron deposition in cortex and hippocampus of the Alzheimer's disease ( AD ) transgenic mice and investigate their influence on T2 relaxation time.Method All AD transgeic mice were divided into three groups: young group(2,4 months), adult group (6,8,10 months), old group (12,14,16 months), and C57BL/6J mice were as control and were scanned in order by using 4.7 T MR system.Regions of interest (ROI) corresponding to cortex, hippocampus,thalamus, striatum were manually drawn on MR images and T2 MR relaxation times of each ROI were calculated.After MR scan, these mice were decapitated and stained for iron and senile palques.The number of plaque and iron, plaque burden, iron load in cortex and hippocampus were acquired using image pro plus software.Result T2 relaxation times of each group were as following: wild type ( cortex (49.5 ± 2.1 ) ms,hippocampus (51.6 ± 1.1 ) ms ); young ( cortex ( 49.7 ± 0.5 ) ms, hippocampus ( 50.7 ± 0.7 ) ms ); adult (cortex(47.2 ±0.8) ms, hippocampus(47.7 ±0.9) ms) and old (cortex(44.6 ±0.8) ms, hippocampus (45.3 ±0.4)ms).T2 relaxation times in cortex and hippocampus of each group had statistical differences ( cortex F = 18.620, P ＜ 0.01; hippocampus F = 67.925, P ＜ 0.01 ); Compared with young group and wild type mice, T2 relaxation times in corex and hippocampus of adult group mice were decreased significantly.At the same time, T2 relaxation times in old group mice were reduced compared with adult group ( Adult vs young: cortex q =4.284, P ＜0.01, hippocampus q =7.902, P ＜0.01; adult vs wild type: cortex q =4.424, P＜0.05, hippocampus q = 11.450, P ＜0.01; old w adult: cortex q =4.812, P ＜0.01,hippocampus q = 7.034, P ＜ 0.01 ).Histochemical staining for senile plaques found that senile plaques was deposited as early as 4 month.Iron deposition in hippocampus and cortex were detected by perl-DAB as early as 6 months of age, and there was an overall increase in number and load of plaques and iron with age.A positive correlation was observed between plaque burden and iron load ( r = 0.931, P ＜ 0.01 ).At the same time, plaque burden and iron load were negatively correlated with T2 relaxation times ( plaque burden and T2 relaxation times r = - 0.884, P ＜ 0.01; iron load and T2 relaxation times r = - 0.827, P ＜ 0.01 ).Conclusion The changes of T2 relaxation time in AD transgenic mice are attributed to iron and senile plaques.MR T2 relaxation time is a sensitive marker to diagnosis for AD and screen antidementia drugs.

Objective To investigate the clinical value of 64-slice computed tomography with MinIP and MPR for imaging the bronchus related to a solitary pulmonary lesion (SPL). Methods Seventy-five subjects with solitary pulmonary lesions underwent chest 64-slice CT and their bronchi were analyzed retrospectively. All images of thin-section (0.625 mm) were reconstructed with MPR and MinIP into images of 1, 2, 3, and 5 mm thickness and 1 mm gap in two orthogonal planes along the long axis of bronchus related to the SPL. The image quality of four series of MinIP and MPR images was evaluated in the aspect of bronchus visibility and pulmonary vascular masking. One-way ANOVA with Bonferroni correction and interclass correlation coefficient were used in the statistical analysis. Results (1) The mean scores of display of the bronchi on MinIP images of four series (4.85, 4.77 and 4.84, 4.63 and 4.67, 4.25 and 4.28, in 1, 2, 3, and 5 mm thickness, respectively) and on MPR images of 1 or 2 mm thickness (4.77 and 4.76, 4.04 and 4.27, in 1 and 2 mm thickness, respectively) were good or excellent. MPR images of 1 mm thickness and MinIP images of 1-3 mm thickness showed no significant differences (t=0.318, P> 0.05 for all), but they were superior to MinIP images of 5 mm thickness (t=6.318 and 6.610, P＜0.01). MPR images of 2 mm thickness were inferior to MinIP images of 1-3 mm thickness (t=5.003-8.958, P＜0.01), but there was no significant difference between MPR images of 2 mm thickness and MinIP images of 5 mm thickness (t=1.794 and 0.3181, all P> 0.05). (2) The effect of suppression of pulmonary vascular markings on MinIP images was better with the increase of slice thickness (F=45.312 and 40.415, P＜0.01). The mean scores of MinIP images of 3 mm and 5 mm thickness (4.67 and 4.64, 5.00 and 4.97, for 3 and 5 mm thickness, respectively) were good or excellent, but MinIP images of 2 mm thickness were just acceptable. Conclusion MinIP images of 3 mm thickness may display the bronchus related to SPL more clearly.

Objective To evaluate the safety and efficacy of direct celiac ganglion irradiation with 125I seeds for pain relief secondary to advanced pancreatic carcinoma (PC).Methods This study enrolled 23 consecutive patients who had moderate to severe pain resulting from advanced PC.All patients underwent EUS-guided direct celiac ganglion irradiation with 125I seeds.Follow-up was conducted at least once weekly until death.Blood parameters,Visual Analog Scale (VAS) score,mean analgesic consumption,and complications were evaluated during follow-up.Results All patients successfully underwent implantation at one attempt.The mean number of seeds implanted in the celiac ganglion per patient was 4 (range 2-6).Immediately after the procedure,pain relief and analgesic consumption showed no significant changes compared with preoperative values.Six patients (26％) reported pain exacerbation.Two weeks later,the VAS score and mean analgesic consumption were significantly less than preoperative values.No procedure-related deaths or major complications occurred.Conclusion EUS-guided direct celiac ganglion irradiation with 125I seeds can reduce the VAS score and analgesic drug consumption in patients with unresectable PC.

OBJECTIVE:To conduct screening for the active ingredients of Ziziphus jujuba with neuroprotective effect and to il-luminate their mechanisms of action preliminarily. METHODS:After neuron-like cells (PC12 cells) were respectively cultured in the ingredient of Z. jujuba with polysaccharide enriched(1 mg/ml),that with polysaccharide removed(1 mg/ml),7 kinds of flavo-noid ingredients of Z. jujuba(catechin,procyanidine B2,epicatechin,hyperoside,rutin,quercetin-3-β-D-glucoside and kaempfer-ol-3-O-rutinoside,represented by A,B,C,D,E,F,G,all at the concentrations of 3,13,30 μmol/L)and 2 kinds of nucleoside ingredients of Z. jujuba (cyclic adenosine monophosphate and cyclic guanosine monophosphate,both at the concentrations of 3, 13,30 μmol/L)for 24 h,tert-butyl hydroperoxide(tBHP,150 μmol/L)was used to act on PC12 cells for 3 h to induce oxidative cellular damage,and MTT assay was employed to detect the survival rate of PC12 cells. The PC12 cells transfected with reporter gene plasmid(pARE-Luc)were cultured as above for 24 h,luciferase(Luc)assay was used to detect the transcriptional levels of the antioxidant response element(ARE)of all groups of cells(reflected as the activity of Luc)so as to investigate the anti-injury mechanism. RESULTS:The ingredient of Z. jujuba with polysaccharide enriched could significantly increase the survival rate of PC12 cells to which oxidative damage was caused and the transcriptional level of ARE in the transfected cells. Among the flavonoid ingredients of Z. jujuba, A(30 μmol/L),B(3-30 μmol/L)and C(10-30 μmol/L)could significantly increased the survival rate of the cells,and A(30 μmol/L),B(3-30 μmol/L),C(30 μmol/L),E(30 μmol/L)and F(3-30 μmol/L)could obviously in-creased the activation level of ARE in the transfected cells. However,the nucleoside ingredients of Z. jujuba including cyclic ade-nosine monophosphate and cyclic guanosine monophosphate had no obvious effect of increasing the survival rate of PC12 cells to which oxidative damage was caused or activating the transcription of ARE in the transfected cells. CONCLUSIONS:The polysac-charide and flavonoid ingredients of Z. jujuba may be the active ingredients which account for the neuroprotective effect against oxi-dative cellular damage,and their mechanisms of action may be related to the activation of ARE transcription.
