Objective To investigate the common etiologies,sports and learning situation of children in Nantong with short stature,and discuss the relationship between the two. Methods Did a retrospective analysis of 108 cases of children with short stature in Nantong University′s affiliated hospital since January 2012. Through detailed past illnesses, physical examination, laboratory tests, diagnose short stature and clarify the cause. Did a questionnaire to these children with short stature about sports and learning situation. Use statistical methods like multivariate Logis-tic regression analysis and link analysis to analyze sports and learning situation of children in Nantong with short sta-ture and find the relation with the etiology. According to the principle of group matching,the control group elected representative of 108 children. Results In 108 cases, 61 cases were because of growth hormone deficiency (GHD), accounting for 56. 5% ; 47 cases were because of non-growth hormone deficiency (NGHD), accounting for 43. 5% . Logistic regression analysis showed that participation in physical exercise was a protective factor. Rest-less anxiety and inattention were as risk factors,and these make a lot(P < 0. 001, OR = 7. 483, 95% CI = 2. 620 ~21. 374). There was no significant relation between common cause and sports, learning situation ( P > 0. 05). Conclusion Various types of sports (basketball, badminton, running, cycling) are protective factors for children of short stature. Restless anxiety and inattention are risk factors for children with short stature. Whether there is growth hormone deficiency or not, children with short stature should increase the right exercise as much as possible and avoid or reduce exposure to these risk factors.

MicroRNAs(miRNA)are a kind of small non -conding RNA,which negative regulate target genes expression at post -transcription level by binding 3'-untraslation region(3'UTR).Dysregulation of miRNA pro-files relate to cancer,immune disorders,cardiovascular disease,neurodegenerative diseases and metabolic diseases. miR -221 /222 are two similary miRNAs,which share the same promoter and have the same seed sequence.miR -221 /222 usually target to same target genes and co -regulate same processes and act as onco -miRNA roles.Howev-er,miR -221 /222 maybe act as suppressor in cancer which maybe dependent particular context.The roles of miR -221 /222 are reviewed in this article,will provide a comprehensive vision for comprehending the biological process of miR -221 /222 in carcinoma.

Objective To deduce the interactions between genes from time series microarray data.Methods We used inter-transaction association rules mining technique and GO (Gene Ontology) annotation to analyze the microarray data. Results Using 2-fold-change method, 119 differential expression genes were identified from total 10 080 genes or ESTs, whose expression levels varied significantly on 6 periods of fetus cerebellar development. As a result, about 1 300 inter-transaction association rules were extracted and 10 top rules were kept for their maximum J-measure values. A genes association network graph was deduced based on the 10 top rules. Conclusion Inter-transaction association rules are able to deduce the interactions between genes from time series microarray data and the gene expression status can be predicted based on the association rules.

Objective: To investigate the relationship of nm23 and VEGF expression with hilar lymph node micrometastasis and the prognosis of stage Ⅰ non-small cell lung cancer (NSCLC). Methods: Immunohisto-chemistry was used to detect nm23 and VEGF protein expression in primary cancer tissue and cytokeratins in 86 hilar lymph nodes from 40 patients with stage Ⅰ NSCLC. Kaplan-meier method and Log rank test were used to analyze the 5-year survival. Results: The rate of positive hilar lymph node micrometastasis was 12.5% for stage Ⅰ NSCLC. Lymph node micrometastasis was not statistically correlated with gender, age, histologic type, differentiation, primary tumor size or VEGF protein expression (P>0.05). But it was reversely associated with nm23 protein expression in primary cancer tissue of NSCLC (P<0.05). The 5-year overall survival of pa-tients with well-differentiated NSCLC, positive nm23 expression and negative lymph node micrometastasis was better than those with moderately and poorly differentiated NSCLC, negative nm23 expression and posi-tive lymph node micrometastasis (P<0.05). Lymph node micrometastasis and nm23 protein expression were identified as two independent prognostic factors for stage Ⅰ NSCLC by univariate Cox regression analysis.Conclusion: nm23 protein expression in pdmary cancer tissue of stage Ⅰ NSCLC is closely associated with hi-lar lymph node micrometastasis, nm23 protein and hilar lymph node micrometastasis are two independent prognostic factors for stage Ⅰ NSCLC. Patients with nm23 protein deletion and positive lymph node microme-tastasis have a poor prognosis.

Objective To investigate the factors related to outcome (recovery of motor, activities of daily living, and balance) of stroke patients. Methods 67 stroke patients with hemiplegia were evaluated with the Ueda Classfication of upper and lower limbs function, Functional Independence Measure (FIM), Berg balance scale (BBS) before and after treatment. The scores of all the assessment were as the dependent variable respectively, and regression analyzed with the factors possiblely related to the outcome. Results The positive factors for lower limbs function included rehabilitation intervention, time of rehabilitation, and hypercholesterolemia; while the negative factors were body mass index (BMI), and damage of superficial sensibility. The positive factors for upper limbs function were rehabilitation intervention and time of rehabilitation; while the negative factors were BMI, dysphagia, damage of superficial sensibility, and frequency of attack. The positive factors for hand function were rehabilitation interventions and interval from diagnosis to rehabilitation, while the negative factors were the muscle tension, incontinence, and frequency of attack. The positive factors for FIM were the rehabilitation intervention, while the negative factors were BMI, incontinence, hypercholesterolemia, gender and residence status. The positive factors for BBS were the rehabilitation intervention, while the negative factors were BMI, frequency of attack, and hyperglycemia. Conclusion Rehabilitation promotes the recovery of stroke patients, but the BMI may block it.

Objective To explore the pattern of functional reorganization in the cortex after corticospinal tract ( CST) injury and its relationship with the recovery of upper limb motor function. Methods Fifteen patients with complete paralysis on one side after acute cerebral infarction were studied. Within 1 week after the onset, func-tional magnetic resonance imaging ( fMRI ) and diffusion tensor tractography ( DTT) were performed in parallel with timed finger flexion and extension movements in all subjects. The number of nerve fibers in corticospinal tract ( CST) in the affected and healthy sides was measured by using Dtv.Ⅱ. R2 software. One and three months later, fMRI was performed while the affected fingers were flexed and extended passively and any cortical activation was observed. In addition, Fugl-Meyer arm motor function scores were assessed one week, one month and three months after the stroke. Results According to the reconstructed nerve fiber number in CST on the affected side, the patients were classified into three types. Type I:the number of newly-built CST nerve fibers is more than 2/3 of that on the healthy side;type II:the ratio is between 1/3 and 2/3;and type III:the ratio is less than 1/3. For typeⅠpatients, blood oxygenation level-dependent fMRI ( bold-fMRI) showed initial activation of the bilateral sensorimotor cortex ( SMC) and the sup-plementary motor area ( SMA) on the affected side. That was followed by a gradual decrease in the activity in the healthy SMC and an increase in the affected SMC at 1 and 3 months. Among the type II patients bold-fMRI indicated activation of the SMC and SMA on the affected side initially, significant activation of the bilateral SMC and SMA one month later and then stronger activation in the SMC on the healthy side and a weakening of activation in the SMC on the affected side. For typeⅢpatients, initially the SMA and the posterior parietal cortex were found to be slightly ac-tivated. One month later SM1 on the unaffected side was slightly activated, and 3 months later neither the SMC nor the SMA on either side was activated. One week after the onset, the average upper extremity FM scores of the three types of subjects were not significantly different. After one month the three groups′averages were all significantly dif-ferent from one another. But after three months the averages for types I and II were again not significantly different, but significantly better than the average of the type III patients. Conclusion Different CST injuries induce different modes of cortical reorganization. The reorganization is a dynamic process, and different activation patterns are closely correlated with clinical prognosis.
