Objective:To establish a three-dimensional finite element model of maxillary complex with cleft palate.Methods:Spiral CT scanning images of maxilla were obtained from a male patient with cleft palate.The data were used to build up different range finite element model of maxillary structure with cleft palate using ANSYS software.Result:The model of maxillary complex with cleft palate could reflect the maxillary structural properties of the cleft palate.Conclusions:Combined with spiral CT and ANSYS software technique finite element model of cleft palate maxillary complex can be established.

Objective:To observe the acoustic characteristics of glottal stops produced by patients with cleft palate.Methods:Twenty boys with cleft palate who were judged to be glottal-stop-producers and 20 normal peers were included. In their own way, all the children were asked to produce following sounds: /iu/ /pai/ /t′u/, /s/ /k′/ /p′u/ /t′u/, /tA/ /ku/ and /i/ /k′u/ /ti/ /suan/. Then the speech spectroanalysis and the comparison were performed by one investigator.Results:The acoustic characteristics of glottal stops changed a lot when they substitute or accompany with different oral stops, which included the emergence of spikes, changes of voice onset time, the formant transitions and spetroanalysis of spikes. Conclusion:The acoustic changes of glottal stops are complicated. Every single aspects of acoustic analysis should be considered in the identification of the acoustic characteristics.

ObjectiveTo investigate the efficacy of acupuncture point injection for fine motor functions in children with cerebral palsy.Methods57 children with cerebral palsy were treated by acupuncture point injection combined with occupational therapy. The efficacy was evaluated by the Peabody Developmental Motor Scale-Fine Motor (PDMS-FM).ResultsThe fine motor quotient (FMQ) of 34 children (59.7%) elevated. The raw scores of grasping subtest (Gr) elevated in 45 children (78.9%) and the raw scores of visual-motor integration (VI) elevated in 53 children (93.0%).ConclusionThe efficacy of acupuncture point injection combined with occupational therapy is significant in children with cerebral palsy.

OBJECTIVERadial corrective osteotomy is an established but challenging treatment for distal radial malunion. There is an ongoing discussion about whether an opening or closing-wedge osteotomy between should employed. The purpose of the present study was to retrospectively compare the clinical and radio graphic results between conventional opening-wedge osteotomy and closing-wedge technique.

METHODSFrom January 2004 and December 2012,42 patients with extra-articular distal radial malunion were managed with corrective osteotomy and were followed for a minimum of one year. Twenty-two patients (5 males and 17 females, ranging in age from 25 to 75 years old) were managed with radial opening-wedge osteotomy and implanting of interpositional bone graft or bone-graft substitute, and twenty patients (4 males and 16 females, ranging in age from 19 to 79 years) were managed with simultaneous radial closing-wedge and ulnar shortening osteotomy without bone graft. The selection of the surgical procedure was determined by the surgeon. Each patient was evaluated on the basis of objective radio graphic measurements, and functional outcomes were determined on the basis of clinical examinations, including range of wrist motion, grip strength, pain-rating score, Mayo wrist score, and Disabilities of the Arm, Shoulder and Hand (DASH) score.

RESULTSThe mean duration of follow-up was 36 months (ranged, 12 to 101 months) for the opening-wedge cohort and 28 months (ranged, 12 to 87 months) for the closing-wedge cohort. The two techniques were comparable in terms of complications. Post-operative volar tilt and ulnar variance were improved significantly in each cohort. The ulnar variance was more frequently restored to within defined criteria (22.5 to 0.5 mm) in the closing-wedge cohort than that in the opening-wedge cohort. The post-operative mean extension-flexion are of the wrist and Mayo wrist score were significantly better in the closing-wedge cohort. Differences in the pronation-supination arc, grip strength, pain-rating score, and DASH scores between these two cohorts were not significant.

CONCLUSIONThe closing wedge osteotomy technique is an effective reconstructive procedure for the treatment of extra-articular distal radial malunion. It is significantly better than the opening-wedge osteotomy technique in terms of the restoration of ulnar variance, the extension-flexion arc of wrist motion, and the Mayo wrist score.

[ ABSTRACT] AIM:To cultivate stem-like spheres from SW620 cell line in the specific serum-free medium and evaluate the features of the cancer stem cells, and to investigate the effects of docosahexaenoic acid ( DHA) and eicosapen-taenoic acid ( EPA) on the growth of SW620 stem cell-like cells.METHODS: Human colon cancer stem cell-like cells ( CSCLC) were obtained from SW620 spheres cultured in serum-free medium.These cells were tested for the expression of SSEA-1 and TRA-1-81 by immunofluorescence staining.The mRNA expression of Sox-2 and Oct-4 was detected by real-time PCR.The efficiency of colony formation on a soft agar gel and tumor formation in the nude mice was compared between SW620 adherent cells and CSCLC.The inhibitory effects of 5-fluorouracil (5-FU) and mitomycin C on both types of cells were measured by MTS assay.MTS assay, Annexin V/PI staining and trypan blue staining were used to determine the effects of DHA and EPA on both types of cells.MTS assay was also used to analyze the combined effect of DHA or EPA with chemotherapeutic drugs on SW620 CSCLC.RESULTS:SW620 cells formed spheres in serum-free culture.The cells from spheres highly expressed SSEA-1 and TRA-1-81, transiently expressed Sox-2 and Oct-4 genes and were more resistant to 5-FU and mitomycin C treatments.These cells exhibited a greater ability in clone formation and tumorigenicity, indica-ting that these cells carried stem cell-like features, hence were considered SW620-derived CSCLC.DHA and/or EPA sup-pressed SW620 CSCLC by inhibiting cell growth, inducing cell apoptosis and sensitizing them to chemotherapeutic drugs. CONCLUSION:The cells with stem cell-like features, such as high efficiency in clonogenicity, tumorigenicity and resist-ance to chemotherapeutic drugs, can be obtained from SW620 spheres cultured in serum-free condition.DHA and EPA in-duce apoptosis in SW620-derived CSCLC and sensitize them to chemotherapeutic drugs.

ObjectiveTo analysis the clinical characteristics and the high risk factors of children with cerebral palsy.MethodsClinical data of 100 children with cerebral palsy were retrospectively analyzed.Results51% of children were born with asphyxia, 42% were born prematurely, 39% were low birth body weight. 85.7% of children involved had mental retardation, 12% had hearing loss and 7% had visual impairment. 88% of children involved had abnormal cranial CT results and 46.1% had abnormal EEG. 50.0% of the children had abnormal brain stem auditory evoked potentials.ConclusionAsphyxia, prematurely birth and low birth body weight are high risk factors of cerebral palsy. Most of the children with cerebral palsy in this group are mental retarded.

Objective To investigate the effects of the interaction between human hepatoma cells and hepatic stellate cells on their growth state,and study its role of interaction on the progression of hepatocellular carcinoma.Methods Human hepatoma cell line HepG2 and hepatic stellate cell line hepatic stallate cells (HSC)-T6 were used and the methods including methyl thiazolyl tetrazolium (MTT) assay,flow cytometry (FCM) analysis,immunohistochemistry,and electron microscopy were employed in this experiment.The effects of conditioned medium (CM) of HepG2 on the activation and proliferation of HSC were explored.The effects of activated HSC CM on HepG2 proliferation were investigated.The uhrastructural changes of the two co-cultured cells were observed.Results MTT assay result showed that HepG2/HSC CM could promote HSC/HepG2 proliferation.FCM result demonstrated that HepG2/HSC CM could influence the cell cycle distribution in HSC/HepG2.Immunohistochemistry exhibited that after the treatment of HepG2/HSC CM,the expression ofα-smooth muscle actin (α-SMA) in HSC and proliferating cell nuclear antigen (PCNA) in HepG2 were increased.When HepG2 and HSC were co-cultured,the ultrastructure of HSC displayed an activated feature.Conclusions HepG2 cells can induce the activation and proliferation of HSC,and the activated HSC can also stimulate the proliferation of HepG2.Interaction between hepatoma cells and hepatic stellate cells may play an important role in the progression of hepatocellular carcinoma.
