Objective To analyze the content validity of Gross Motor Function Measure (GMFM) for cerebral palsy. Methods Concept contained in each item of GMFM was determined by 3 rehabilitation physicians or therapists who evaluated with GMFM for more than 2 years. All the concepts extracted were discussed in a meeting. The terms finalized were linked to the categories of International Classification of Functioning, Disability and Health Child and Youth version (ICF-CY) by 2 rehabilitation physicians who are familiar with the terms of ICF-CY according to the linking rules after discussion. Third party would intervene informally if there was a disagreement. The distribution of the ICF-CY categories involved were analyzed. Results 88 items from the GMFM linked to 27 categorise of 3rd level within 12 categories of 2nd level, belong to b7 Neuromusculoskeletal and Movement-related Functions and d4 Activities. 86 items linked to d4x, and 47 of then linked to b7x too. 2 items linked to b7x only. 16 items linked to the categories added to ICF-CY 16 times, involved 3 3rd level categories in a 2nd level category. Conclusion GMFM mainly focused on the activities in the framework of ICF-CY, especially the activities of changing and maintaining functional as well as the body posture and walking or moving. For the body function, the GMFM mainly focus on the support from arms.

BACKGROUND: This study aimed to investigate the epidemiological and clinical characteristics of patients with heat-related il ness, and guide the prevention, diagnosis and treatment of heat-related il ness. METHODS: From June 2013 to August 2013, seventy patients with heat-related illness were treated at Jinshan Hospital of Fudan University, and their epidemiological characteristics, laboratory results, treatment and prognosis were retrospectively analyzed. RESULTS: In the 70 patients, 18 patients suffered from heat stroke and 52 patients from non-heat stroke. When the environmnent temperature was above 35 °C, the body temperature of the patients began to increase markedly. The patients with heat stroke were significantly older than those with non-heat stroke (P<0.05). The body temperature, heart rate, blood glucose, blood lactate dehydrogenase and blood creatine kinase in the patients with heat stroke were higher than those in the patients with non-heat stroke (P<0.05). Blood lactate dehydrogenase and blood creatine kinase were positively correlated with body temperature (r=0.801). CONCLUSION: When the environmental temperature goes above 35 °C, heat-related illness should be prevented, especially in the elderly. The body temperature, heart rate, blood glucose, blood lactate dehydrogenase and blood creatine kinase in patients with heat stroke are higher than those in patients with non-heat stroke. Blood lactate dehydrogenase and blood creatine kinase are positively correlated with body temperature, but their relationship with heat-related illness awaits further study.

OBJECTIVEUndried silver-hydroxyapatite-titania (Ag-nHA-nTiO2) nanoparticles slurry was used to make membrane with polyamide 66 (PA66) by co-polymerization method. The purpose of this study is to test the physical and chemical characteristics and antibacterial ability.
METHODSThe morphology, chemical components and structures of the membrane were characterized by atomic absorption spectrometer (AAS), X-ray diffraction (XRD), scanning electron microscope (SEM) and energy-dispersive X-ray analysis (EDX). Staphylococcus aureus (S. aureus), Escherichia coli (E. coli), Porphyromonas gingivalis (P. gingivalis), Fusobacterium nucleatum (F. nucleatum) and Streptococcus mutans (S. mutans) were utilized to test the antibacterial effect.
RESULTSXRD results demonstrated that the membrane have characteristic diffraction peaks of pure hydroxyapatite (HA). A homogeneous distribution of the Ca, P, Ti and Ag element in the membrane was confirmed by EDX. Both surface and section showed porous structure which was confirmed by SEM and the average hole size was 20-30 microm. The bacteria assay reflected to the antibacterial effect, 50.10% of S. aureus and 56.31% of E. coli were killed. However, 91.84% of P. gingivalis, 90.64% of F. nucleatum and 90.49% of S. mutans were killed and pictures of SEM showed obviously fewer cells on the surface.
CONCLUSIONThe nanocomposite membrane could be one of the bioactive materials with antibacterial properties for oral guided bone regeneration technique.

OBJECTIVETo study the clinical characteristics of male urethral duplication infection and offer some guidelines for the diagnosis and treatment of the disease.
METHODSWe analyzed the pathological types, clinical characteristics, therapeutic processes and follow-up results of 9 cases of male urethral duplication.
RESULTSAmong the 9 cases of urethral duplication, 7 turned out to be of Type I, 1 Type II A2 and 1 Type II B. The disease courses varied from 2 to 420 days, with an average of 77.2 +/- 141.5 days. Four cases with longer disease duration were identified with a history of repeated use of various antibiotics for treatment. Their clinical manifestations varied, with the outflow of excretions or pus from the duplicate or normal urethra as the cardinal symptoms. The pathogens detected from the secretions were mainly Neisseria gonorrhoeae, Ureaplasma urealyticum, and Chlamydia trachomatis. The consistency rate of the same pathogens detected in the vaginal or cervical secretions from the sex partners of the patients was 87.5%. All the symptoms disappeared after a sufficient-course treatment with sensitive antibiotics, and the patients' sex partners received the same medication simultaneously. No recurrence was found during a 3-month follow-up.
CONCLUSIONUrethral duplication infection has various clinical manifestations, and thus is easily missed in diagnosis. Sufficient-course treatment with sensitive antibiotics is recommended for those that prefer conservative therapy, and their sex partners should be treated simultaneously.

Objective To evaluate contrast-enhanced fluid-attenuated inversion recovery (FLAIR) imaging in the detection of leptomeningeal lesions.Methods Seventeen patients with a variety of leptomeningeal lesions were analyzed.The MRI protocol included un-enhanced and contrast-enhanced FLAIR images and contrast-enhanced T_1WI,Comparisons between contrast-enhanced FLAIR images and T_1WI and between un-enhanced and contrast-enhanced FLAIR images were made to determine which sequence better depicted the lesions.Results Leptomeningeal lesions showed as either diffusely or locally abnormal hyper-intensity along sulci or cistern on three sequences.Comparison between contrast-enhanced FLAIR and T_1WI showed that only contrast-enhanced FLAIR revealed the abnormalities in 7,both revealed the abnormalities but the former was superior in 2 ,and both were conspicuous in 7. In 1 patient of tuberculous meningitis,diffuse abnormalities of sulci were shown only on contrast-enhanced FLAIR, abnormalities of cisterns were shown on both sequences but the former was superior.Comparison between un- enhanced and contrast-enhanced FLAIR showed that only contrast-enhanced FLAIR revealed the abnormalities in 9,both revealed the abnormalities but the former was superior in 3,and both were conspicuous in 4. In 1 patient of tuberculous meningitis,abnormalities of cisterns were shown only on contrast-enhanced FLAIR,diffuseabnormalities of sulci were shown on both sequences but the former was superior.Conclusions Contrast-enhanced FLAIR images were superior to un-enhanced FLAIR images and contrast-enhanced T_1WI in the detection of leptomeningeal lesions. Contrast-enhanced FLAIR images are helpful and should be considered when findings on un-enhanced FLAIR images and/or contrast-enhanced T,WI are inconclusive.

OBJECTIVETo study a possible association between the three functional polymorphisms in the promoter region of dopamine D4 receptor (DRD4) gene and chronic tic disorder.
METHODSGenomic DNA was isolated from the venous blood leukocytes of 84 unrelated patients with chronic tic disorder (Study group) and 100 healthy unrelated individuals (Control group). Polymorphisms of DRD4, 1240L/S, 616C/G and 521C/T, were genotyped by the allele-specific primer (ASP) PCR. Genotype, allele and haplotype frequencies were analysed by SHEsis online.
RESULTSThere were significant differences in both allele and genotype frequencies (chi(2) = 8.419, P < 0.01; chi(2) = 7.860, P < 0.05 respectively) of DRD4-616C/G between the Study and the Control groups. Haplotypic frequencies of LCT (1240L/S, 616C/G, 521C/T) in the Study group were noticeably higher than in the Control group (chi(2) = 6.371, P < 0.05).
CONCLUSIONSThere is an association between the DRD4-616C/G polymorphism and chronic tic disorder. The individuals with haplotype LCT (1240L/S, 616C/G, 521C/T) are susceptible to this disorder.

AIMTo explore the effect of Triptolide on airway remodeling and the expression of Phosphoinositide 3-Kinases in asthmatic rats.
METHODS40 rats were randomly divided into 5 groups (n = 8): (1) Control group; (2) Asthmatic 4 weeks group; (3) Asthmatic 6 weeks group; (4) Therapeutic 4 weeks group; (5) Therapeutic 6 weeks group. The airway resistance and eosinophilic inflammation of airway wall were observed. The airway wall thickness (WA/Pi), the bronchial smooth muscle thickness (smooth muscle area/Pi) and the number of bronchial smooth muscle nucleus (N/Pi) were measured by image analysis system. The expression of PI3K protein and mRNA were determined by immunohistochemical staining and reverse transcription-polymerase chain reaction (RT-PCR).
RESULTS(1) The expression of PI3K p85alpha protein and mRNA in asthmatic 4 weeks group and asthmatic 6 weeks group were significantly higher than control group, respectively (P < 0.01). The above-mentioned parameters of therapeutic 6 weeks group were significantly lower than those of asthmatic 4 weeks group, asthmatic 6 weeks group and therapeutic 4 weeks group, respectively (P < 0.01, P < 0.01 P < 0.05). (2) The WA/Pi, the smooth muscle area/Pi and the N/Pi of asthmatic 4 weeks group and asthmatic 6 weeks group were significantly higher than control group, respectively (P < 0.01). The above-mentioned parameters of therapeutic 6 weeks group were significantly lower than those of asthmatic 4 weeks group, asthmatic 6 weeks group and therapeutic 4 weeks group, respectively (P < 0.01). (3) The airway resistance of asthmatic 4 weeks group and asthmatic 6 weeks group were significantly higher than the control group, respectively (P < 0.01). The above-mentioned parameters of therapeutic 6 weeks group were significantly lower than those of asthmatic 4 weeks group, asthmatic 6 weeks group and therapeutic 4 weeks group, respectively (P < 0.01, P < 0.01, P < 0.05).
CONCLUSIONThe proliferation of airway smooth muscle is a remarkable character of airway remodeling in asthma. The PI3K signal pathway may be involved in the process. Triptolide may reduce AHR and decrease the proliferation of ASMCs by inhibiting the expression of PI3K. It may have potential therapeutic effects in the asthmatic airway remodeling.

OBJECTIVETo explore genetic background of a pedigree with a rare p phenotype from Guangdong province.
METHODSThe rare p phenotype was identified by a conventional serologic method. With genomic DNA of proband and family members extracted, exon 3 of alpha-(1,4)galactosyltransferase (A4GALT) gene was amplified with PCR and analyzed by direct sequencing. The mutation found in the pedigree was screened in a normal population using direct sequencing.
RESULTSThe proband and 4 family members with the rare p phenotype have all carried a point mutation c.100G>A (p.Val34Ile) in combination with a deletion-insertional mutation c.418_428del11ins34(p.Gln139Trpfs*72), which renders a compound mutation of A4GALT gene. One family member with P2 phenotype has carried a same heterozygous mutation. Of the 100 healthy donors, 5 have carried a heterozygous point mutation c.100G>A, and none carried the deletion-insertional mutation c.418_428del11ins34.
CONCLUSIONThe rare p phenotype of the pedigree has resulted from a compound mutation of the A4GALT gene, which is in keeping with a recessive inheritance pattern of the p phenotype.
