Objective To observe the therapeutic efficacy of acupuncture plus speech training for speech disorders in children with cerebral palsy based on the sign-significant relations (S-S) method for checking language development delay and dysarthria score. Method Ninety patients with spastic cerebral palsy presenting with speech disorders were randomized into a treatment group and a control group by random number table, 45 cases in each group. The treatment group was intervened by acupuncture plus speech training, while the control group was by speech training alone. The improvement of speech function and the relationship between age and therapeutic efficacy were evaluated after 3 treatment courses. Result The total effective rate was 82.2% in the treatment group versus 60.0%in the control group, and the difference was statistically significant (P<0.05);in the treatment group, there were significant differences in comparing the therapeutic efficacy between different age groups (P<0.05). Conclusion Compared to speech training alone, acupuncture plus speech training can produce a better efficacy in treating speech disorders in cerebral palsy;the younger the patient, the better the prognosis.

Objective:To investigate the expression and clinical significance of microRNA-30a in renal cell carcinoma (RCC). Methods:The miRNA-30a expression in renal tissues and cell lines was detected using quantitative real-time polymerase chain reac-tion (qRT-PCR), and the relationship between miRNA-30a expression and the clinicopathological features of RCC was analyzed. The effect of miRNA-30a on cancer cells was evaluated using methyl thiazolyl tetrazolium (MTT) assay. In addition, a bioinformatics algo-rithm was adopted to predict the potential targets of miRNA-30a. Results:miRNA-30a was downregulated both in RCC tissues and cell lines. Patients with higher miRNA-30a expression exhibited better prognosis than those with lower miRNA-30a expression. Bioin-formatics algorithm and qRT-PCR both indicated that metadherin (MTDH) was a target of miRNA-30a. Moreover, MTT results showed that miRNA-30a could inhibit cell proliferation. Conclusion:miRNA-30a was inhibited in renal cancer, and low miRNA-30a expres-sion was associated with poor prognosis. In addition, miRNA-30a could inhibit the growth of cells through MTDH.

Recently,to assess the reproductive effects of bisphenol A (BPA),the environmental estrogen,has become a focus of stusy. Investigations,to date,have focused on the effects on the reproductive system including the morphogenesis of tissues and organs,endocrine and the toxic mechanisms of action,particularly in males. Based on the study results concerning BPA’s impacts on male reproduction,the further study directions in this field were presented in this paper.

Objective To explore the feasibility of in-flow inversion recovery (IFIR)sequence of magnetic resonance imaging (MRI)at 1.5T in diagnosis of Budd-Chiari syndrome (BCS).Methods A total of 45 patients with Budd-Chiari syndrome diagnosed by surgery or interventional surgery in our institution were enrolled.The prerequisite of the study was that all medical imaging data including MRI and digital subtraction angiography (DSA)should be integrated.Then,the diagnostic accuracy rates between IFIR sequence and DSA were analyzed and compared.Results Of all 45 patients with BCS,40 (88.9%)were diagnosed accurately by IF-IR sequence,including typeⅠa in 10,typeⅠb in 14,typeⅡ in 10 and type Ⅲ in 6.Meanwhile,41 (91.1%)were diagnosed accu-rately by DSA,including typeⅠa in 8,typeⅠb in 14,typeⅡ in 13 and type Ⅲ in 6.No significant difference was showed in diag-nostic accuracy between two imaging methods (P >0.05).Spearman rank correlation analysis revealed that the diagnostic accuracy of IFIR sequence was highly consistent with that of DSA(r =0.853,P <0.001 ).However,there existed significant difference be-tween two methods in accurate diagnosis of typeⅠa and typeⅡ BCS (P <0.05).Conclusion MRI IFIR sequence at 1.5T is highly consistent with DSA in diagnosis and classification of BCS,which can be used as a reliable method of preoperative screening for BCS diagnosis.

Objective To evaluate immunogenicity of the recombinant protein GST-p55/570 of Pneumocystis carinii.Methods The fusion protein GST-p55/570 was expressed from the prokaryotic expression plasmid pGEX-570,and purified by using glutathione-agarose.The expressed product was analyzed by SDS-PAGE.Thirty-three mice were randomly divided into three groups,immunized with GST-p55/570,GST and PBS,respectively.Each group was immunized for four times at 2 week intervals.At the 7th day after final immunization,spleen was removed to obtain single cell suspension.Proliferation ability of lymphocytes was determined by MTT.Serum samples were collected at pre-immunizaton and two weeks after each immunization.Antibody level in sera of mice was determined by ELISA.The immune response to the recombinant GST-p55/570 recognized by sera of immunized mice was examined by Western blotting.Results The expressed fusion protein GST-p55/570 showed a Mr 47 000.Compared with GST group(1.134 5?0.073 5) or PBS group(1.124 8?0.041 6),a higher stimulation index(2.063 0?0.160 2) was revealed in GST-p55/570-immunized mice(P

Sleep takes an important role in maintaining typical development, neural plasticity, and language development. Not only poorer performance in memory and cognitive functions, but also obvious delayed language development are seen in children and adolescents with sleep problem. Previous research found that sleep duration affects children and adolescents' ability in comprehensive vocabulary, expressive vocabulary, and vocabulary retention. Children and adolescents with poor sleep quality usually show language developmental delay, however, there is no integrated evaluation tool for sleep and language, and a consistent conclusion is therefore not reached. Daytime naps are beneficial to consolidate vocabulary learning in infants, and it’s also relevant to vocabulary retention and generalization in children and adolescents. Children with sleep related breathing disorders show lower ability in receptive language comprehension and lower lexical level, and with the increase of their age, the severity of their language disorder becomes higher. Besides, sleep can promote language learning in children with neuro-developmental disorder.The neuro-physiological mechanism underlying sleep and language remains unknown, and one of the possible explanations is that sleep problem harms the information processing in frontal lobe and hippocampus, and interferes with neural plasticity. The injury includes memory, attention, executive function, auditory processing, and so on, and finally language development is damaged. Further research is necessary to clarify the relation and mechanism between these two elements, this will be helpful in finding out an effective way to promote language function in children with language retardation and/or combined with neuro-developmental disorder.

Objective To understand the status of renal function abnormalities and explore its influencing factors in a community-based population with type 2 diabetes mellitus (T2DM).Methods Totally 9 413 patients with T2DM who have registered and received management of community public health service in 2014 were recruited in our study.All participants undertook questionnaire survey,physical examination and laboratory test.A simplified MDRD formula was used for estimating Glomerular Filtration Rate (eGFR),and Logistic Regression method was used to analyze the risk factors.Results The average eGFR was 91 ml/min · 1.73 m2 and the attack rate of people with eGFR ＜60 ml/min 1.73 m2 was 10.56％.The difference of renal function in participants with different age and gender was significant(x2 =6.306,P =0.012;x2 =269.293,P ＜ 0.001).Renal function in male patients and older patients was more worse.Multivariate analysis showed that long duration of diabetes,high levels of low density lipoprotein (LDL),total cholesterol (TC) and triglycerides (TG),uncontrolled blood glucose were independent risk factors for renal dysfunction.Conclusions Patients with T2DM are susceptible to renal function abnormalities.Comprehensively control of blood glucose,blood lipid and blood pressure should be performed to decrease the risk of the disease.

To construct the eukaryotic expression plasmid containing the p55 gene fragment of Pneumocystis and to investigate the efficient expression in COS-7 cells, the gene fragment conaining the whole length of p55 gene was used as template to amplify this fragment with PCR and the amplified fragment was then cloned to vector pGEM-T. After enzyme digestion, p55 gene was cloned to the eukaryotic expression vector pcDNA3.1(+) to construct the plasmid pcDNA3.1(+)-582. This plasmid was then transfected to the eukaryotic expression cells COS-7 and PCR and SDS-PAGE assays were used to confirm the presence of target protein in these cells. In these ways, the eukaryotic expression vector for the p55 gene of Pneumocystis of rats was successfully constructed and expressed in COS-7 cells, thus providing the basis for further studies on the nucleic acid vaccine.
