Objective To observe the effects of repetitive transcranial magnetic stimulation (rTMS) combined with rehabilitation training on motor cortex in children with motor retardation. Methods Sixty children with motor retardation were divided into treatment group and control group by random digits table method with 30 cases each. The children in control group were treated with rehabilitation training, and the children in treatment group were treated with rTMS combined with rehabilitation training. Two groups were treated for 3 courses. The Gesell pediatric neuropsychological scale and gross motor function measure (GMFM) scale before and after treatment were evaluated. Results There was no headache, dizziness and abnormal pathological reaction in the 2 groups. The motor behavior development quotient scores of Gesell pediatric neuropsychological scale after treatment in control group and treatment group were significantly higher than those before treatment: (64.37 ± 16.37) scores vs. (62.37 ± 14.21) scores and (74.50 ± 13.32) scores vs. (61.90 ± 13.76) scores, but the score in treatment was significantly higher than that in control group, and there were statistical differences (P<0.05). There was no statistical difference in language behavior development quotient score between after treatment and before treatment in control group: (79.57 ± 5.93) scores vs. (79.07 ± 5.75) scores, P>0.05. The language behavior development quotient after treatment in treatment group was significantly higher than that before treatment:(80.70 ± 5.38) scores vs. (78.57 ± 5.72) scores, and there was statistical difference (P<0.05). The A, B, C and D area scores of GMFM scale after treatment in control group and treatment group were significantly higher than before treatment, which in control group were (76.43 ± 19.18)% vs. (75.40 ± 19.38)%, (50.53 ± 27.63)%vs. (49.60 ± 28.22)%, (31.07 ± 24.93)%vs. (28.40 ± 23.70)%and (1.60 ± 1.33)%vs. (0.89 ± 0.37)%, and in treatment group were (85.80 ± 13.73)%vs. (79.13 ± 16.87)%, (65.77 ± 26.27)%vs. (49.37 ± 29.67)%, (49.60 ± 28.22)%vs. (28.83 ± 23.19)%and (2.10 ± 1.60)%vs. (1.07 ± 0.43)%, and there were statistical differences (P<0.05); the A, B and C area scores after treatment in treatment group were significantly higher than those in control group, and there were statistical differences (P<0.05); but there was no statistical difference in D area score after treatment between 2 groups (P>0.05). Conclusions The rTMS combined with rehabilitation training is better in gross movement than the single rehabilitation training for children with motor retardation. The rTMS can improve the motor function and language ability of children.

Objective To investigate the clinical value of susceptibility weighted imaging (SWI)combined with three dimensional pseudo continuous arterial spin labeling (3D-PCASL)on the prognosis analysis of acute cerebral infarction.Methods Thirty cases with acute cerebral infarction (< 72 h)underwent conventional MRI,MRA,3D-PCASL and SWI.NIHSS scores were performed at the time of examination and 3 months later.The correlation between the collateral blood vessels,regional cerebral blood flow (rCBF)detected by combination of SWI and 3D-PCASL with clinical prognosis were analyzed.Results Twenty-three cases showed collateral blood vessels in the lesions with 1 grade in 14,and 2 grade in 9.The average rCBFs in grade 0,1,2 infarction areas were (22.69±11.94)mL·100 g-1 ·min-1 ,(25.10±16.55)mL·100 g-1 ·min-1 and (33.04±24.24)mL·100 g-1 ·min-1 ,respectively.Collateral blood vessels,rCBF were positive correlated with the NIHSS scores (r=0.989,P< 0.01).18 cases showed multiple vessels around the lesions. The average rCBFs in the infarction area with or not with periphery collateral blood vessles were (28.33±24.24)mL·100 g-1 ·min-1 and (22.69±11.94)mL·100 g-1 ·min-1 ,respectively.There was a positive correlation between rCBF and NIHSS scores (r=0.897,P<0.01). Of 30 cases of acute cerebral infarction,the average CBFs in the infarct areas and the contralateral mirror areas were (26.92±18.22)mL·100 g-1 · min-1 and (34.22±12.37)mL·100 g-1 ·min-1 .There was significant difference (t=8.093,P<0.01).Conclusion The combination of SWI and 3D-PCASL can display the collateral blood vessels in the lesions and soft meninges,and provide the quantitative analysis of rCBF,which has important clinical significance for prediction of the prognosis of acute cerebral infarction.

Objective To study the mutation characteristics in phenylalanine hydroxylase gene of Xinjiang minority nationality phenylketonuria (PKU) patients and provide a scientific basis for PKU prevention and cure strategy.Methods Mutations in phenylalanine hydroxylase gene were detected by Dolymerase chain reaction-single strand comformation polymorphism (PCR/SSCP) and gene sequencing in 12 minoritv nationality patients.Results Thirteen different mutations,including 8 missense mutations,1 nonsense mutation and 3 splice mutations were found in 24 alleles.The moat common mutations were EX696A＞G and P281 L.which were respectively prevalent in Asia and Europe populations.The common mutations were R243Q,R111X,R176X and F161S.The mutation frequency of R243Q was the highest and R111X was the third highest in Northern China.R176X and F161S were two rare mutations world wide.Especially.F161S was a Chinese-specific mutation because it was for the second time that it was found in China.The mutations detected in this study were first reported in these 3 minority nationality populations,which showed a distinct ethical characteristic.Condusions There is not only a consanguineous relation but also a distinct difference in PAH gene distribution between Xinjiang minority nationality population and yellow race and Latin-American.The results suggest that Xinjiang could probably be a special PAH gene distribution region.

Ninety-five patients with acute myocardial infarction (AMI) treated in our hospital from January 2015 to December 2017 were enrolled. According to thrombolysis in myocardial infarction (TIMI) risk score, 95 patients were divided into high group (TIMI>4, n=46) and low group (TIMI≤4, n=49) . According to platelet/lymphocyte ratio (PLR), 95 patients were divided into low PLR group (PLR≤170, n=60) and high PLR group (PLR>170, n=35) . The correlation of PLR with short-term and long-term prognosis in patients with acute myocardial infarction was analyzed. The results showed that there were no significant differences in red blood cell count (RBC), hemoglobin (HB), white blood cell count (WBC), neutrophil ratio (NEU), percentage of intermediate cells (MON), lymphocyte count (LYM), basophils (Bas), red blood cells distribution width (RDW), eosinophils (EO) between high and low TIMI groups ( P>0.05) . The platelet count (PLT) and PLR in high TIMI group was significantly higher than that in low TIMI group ( t=42.196, 10.053; P<0.05) . The in-hospital mortality and all-cause mortality of high PLR group were significantly higher than those of low PLR group [1.67%(1/60) vs. 14.28%(5/35), χ 2=5.949, P=0.02; 3.33%(2/60) vs. 17.14%(6/35), χ 2=5.466, P=0.04]; while there was no significant difference in 1-year re-hospitalization rate, interventional therapy and thrombolytic therapy between the two groups ( P>0.05) . Pearson correlation analysis showed that PLR was positively correlated with TIMI score ( r=0.563, P=0.024) . Logistic regression analysis showed that Killip grade, serum creatinine and PLR were independent risk factors of AMI ( OR=7.532,60.14,8.234; P<0.05). PLR may effectively evaluate the prognosis of acute myocardial infarction, suggesting that its clinical value should be condidered.

PURPOSE: Survival of metastatic breast cancer (MBC) patient remains unknown and varies greatly from person to person. Thus, we aimed to construct a nomogram to quantify the survival probability of patients with MBC. MATERIALS AND METHODS: We had included 793 MBC patients and calculated trends of case fatality rate by Kaplan-Meier method and joinpoint regression. Six hundred thirty-four patients with MBC between January 2004 and July 2011 and 159 patients with MBC between August 2011 and July 2013 were assigned to training cohort and internal validation cohort, respectively. We constructed the nomogram based on the results of univariable and multivariable Cox regression analyses in the training cohort and validated the nomogram in the validation cohort. Concordance index and calibration curves were used to assess the effectiveness of nomogram. RESULTS: Case fatality rate of MBC was increasing (annual percentage change [APC], 21.6; 95% confidence interval [CI], 1.0 to 46.3; p < 0.05) in the first 18 months and then decreased (APC, -4.5; 95% CI, -8.2 to -0.7; p < 0.05). Metastasis-free interval, age, metastasis location, and hormone receptor status were independent prognostic factors and were included in the nomogram, which had a concordance index of 0.69 in the training cohort and 0.67 in the validation cohort. Calibration curves indicated good consistency between the two cohorts at 1 and 3 years. CONCLUSION: In conclusion, the fatality risk of MBC was increasing and reached the summit between 13th and 18th month after the detection of MBC. We have developed and validated a nomogram to predict the 1- and 3-year survival probability in MBC.
