Objective To analyze the comorbidities and gross motor function classifications (GMFCs) of premature children with cerebral palsy (CP) in terms of neurological subtype and gestational age in search of some relationship. Methods Children with cerebral palsy treated at the Qingdao Children's Hospital from 2006 to mid2009 received intelligence capacity tests, ophthalmological consultations, language/speech tests, brainstem auditory evoked potential measurements, electroencephalograms and GMFC evaluations. All of the children were stratified according to neurological subtype, gestational age, comorbidities and gross motor function classification. Results Of all 258 children, spastic diplegic cerebral palsy predominated (183 case, 70.9% ). 124 cases (48.1% ) had visual disorders, 121 (46.9%) had language or speech disorders and 103 (39.9%) showed mental retardation. The frequencies of individual comorbidities were distributed disproportionately between the different neurologic subtypes.GMFC levels also differed with the different CP types. The GMFC levels of diplegics were significantly better than those of the other types. The distribution of comorbidities such as visual disorders, language or speech disorders, and mental retardation was not related to gestational age or type of CP. Conclusions There is some correlation between the neurological subtype, comorbidities and the GMFC levels. But there is no significant correlation between gestation age and the severity of CP.

Objective To observe the lung protection of Astragalus membranaceus against radiotherapy to intermediate-stage and terminal thoracic neoplasm, and its influence on TNF-α and ET expression.Methods The patients with intermediate-stage and terminal thoracic neoplasm under radiotherapy were divided into a treatment group and a control group.Patients in the treatment group took 10 ml of Asragalus membranaceus twice a day.for consecutive 6 months from the beginning of radio therapy.TNF-α and ET in the plasma were measured before and after the radiotherapy.The clinical symptom,iconographic changes and lung diffusion were observed from the 15th day of radiotherapy.Results The TNF-α and ET in plasma afterthe radiotherapy were(2.48±0.75)as/ml and(69.32±23.03)pg/ml for the treatment group,and(5.12±1.01)ns/ml and(97.87±37.83)pg/ml for the control group with the statistial difference(x2=7.49,6.57,P<0.001).The decrease of CO diffusion 5 and 10 months after the radiotherapy in the treatment group was statistically different compared with that in the control group(x2=3.98,3.78,P<0.05).There was a statistical difference of the incidence of acute radiation pneumonitis and pulmonary fibrosis between these two groups(P<0.05).Conclusions Astragalus membranaceus could inhibit the excess expression of TNF-α and ET in plasma and reduce the deterioration of diffusion after radiotherapy,so that it can be used for intervention of lung injuries from radiotherapy.

Objective To investigate neuroimaging and its correlation with clinical aspects of cerebral palsy (CP).Methods A retrospective study of 295 children with CP was conducted.Magnetic resonance imaging (MRI),the gross motor function classification system (GMFCS) and intelligence testing were administered,and any correlations among these measures was analysed.Results Among the 295 cases,257 presented abnormal MRIs (87.1％) due to brain maldevelopment (n =11),periventricular leukomalacia (PVL) (n =173),cortical/subcortical lesions (n =17),basal ganglia lesions (n =26),cerebellar maldevelopment (n =11) or others lesions (n =19).Thirty-nine presented with normal MRIs.About 26％ were rated at GMFCS level 1,18％ at level 2,17％ at level 3,19％ at level 4 and 20％ at level 5.Almost 82％ of the children presented with brain maldevelopment and 84.4％ with PVL-induced spastic bilateral paralysis.In 41％ of the children with cortical or subcortical lesions,induced spastic hemiplegia was observed,whereas 47％ had induced spastic bilateral paralysis.In 77％ of the children with basal ganglia lesions induced involuntary movement was observed,and all of those with maldevelopment of the cerebellum were ataxic.Most of those with spastic hemiplegic,bilateral paralysis,involuntary movement and ataxia were on GMFCS levels 1 or 2,with only 3.7％,33.5％,64.1％ and 46.2％ respectively on GMFCS level 4 or 5.Among those in whom the MRI revealed brain maldevelopment,9.1％ were on GMFCS level 1 or 2.The corresponding percentage for PVL was 43.9％,for cortical or subcortical lesions 58.8％,for basal ganglia lesions 19.2％ and for cerebellar maldevelopment 27.3％.The balance in each category were on GMFCS level 4 or 5.Epilepsy was most common in the children with brain maldevelopment (36.4％) or cortical or subcortical lesions (41.2％).Mental retardation was most common in cases of brain maldevelopment (45.5％),cortical or subcortical lesions (41.2％) or cerebellum maldevelopment (36.4％).The incidence of epilepsy and mental retardation was higher among the children on levels 4 and 5 than on levels 1 and 2.Conclusions Neuroimaging correlates significantly with the type of CP and GMFCS level.Epilepsy and mental retardation are most common in children with brain maldevelopment or lesions.The incidence of epilepsy and mental retardation is higher among children rated at GMFCS level 4 or 5 than among those on levels 1and 2.

Objective To explore clinical characteristics of diagnosis and treatment of solid-cystic papillary tumor(SCPT) of the pancreas in children.Methods There were retrospectively analyzed about the 7 patients treated in our hospital for SCPT,with the ave-rage age of 11.5 years.All patients complained abdominal pain following a trauma(71.4%) or overeating(28.6%).The main presentation was abdominal mass.Of the 7 patients,4 received distal pancreatectomy,2 pancreatico-duodenectomy,and 1 only biopsy.Results The nicks of all patients were primany hed.All patients were pathologically confirmed as SCPT after operation.All patients were followed up for 4 monthes to 4.5 years,the recent result was well.Conclusions SCPT is a low-grade malignant tumor,which is often asymptomatic,but the patients with symptoms generally suffer from an abdominal mass or abdominal pain.The prognosis is excellent after operation.

Objective To examine the interfractional dosimetric variations among inverse three-dimensional (3D) plan, forward 3D plan, and two-dimensional (2D) plan of intracavitary brachytherapy for cervical cancer, and to discuss the risk of implementing the interval plan on different implantation applicators at short time intervals.Methods Twenty-five groups of CT-guided intracavitary brachytherapy (two consecutive radiations at ≤4 d apart) plans from 11 cervical cancer patients who received radical radiation therapy in our hospital were reviewed and compared.The dwelling location and time of the first intracavitary brachytherapy plan (Plan-1) were simulated on the CT image of the second intracavitary brachytherapy to form Plan-1-S.The target coverage indices and D 2 cc of organs at risk (OARs) of Plan-1-S and Plan 2(actual plan of the second intracavitary brachytherapy) under the three planning modes were recorded and compared using the paired t-test, Wilcoxon signed rank test, and ANOVA.Results The D90, D100, and V100 of high-risk CTV were significantly lower in Plan-1-S created under the inverse mode in the actual plan (-9.11±13.46%,-13.16±18.79%, and-7.80±13.34%, P=0.002, 0.002, and 0.005, respectively).D90, D100, and V100 of the interval plan had the greatest reduction under the inverse mode (76%, 80%, and 76%, respectively).The maximum reductions in D90, D100, and V100 were 332.14 cGy (2D), 244.12 cGy (forward), and 41.76%(inverse).OAR overdose occurred most frequently under the forward mode;the rates of D90, D100, and V100 reductions accompanied by one OAR overdose were 29.41%, 37.50%, and 25.00%, and the rates of D90, D100, and V100 reductions by two OAR overdoses were 5.88%, 12.50%, and 6.25%,respectively.Overdose occurred most frequently in the small intestine (36%).Comparison of the three planning modes showed that the inverse plan had a greater reduction in each target coverage index than the 2D plan.Conclusions The simulated interval plan can significantly reduce target coverage and increase the risk of OAR overdose regardless of the planning mode and the short time intervals, and is therefore not recommended for clinical application.

Objective To introduce treatment of old scaphoid fractures by internal fixation with common screws which have been modified into compression-like ones.Methods Twenty-five patients with old scaphoid fracture were admitted to our department from January,1995 to December,2002.They were 17 cases of delayed union,and eight cases of non-union and pseudoarticulation formation.All the patients were treated with open re- duction anti internal fixation by modified common cortical bone screws,some threads of which bad been erased so that they could act somewhat like compression ones.The modified screws were driven into the reduced scaphoid by simple surgical instruments to fix and compress the fracture ends.Results Nineteen cases were followed up for one to six years (mean,3 years).Fourteen cases of fracture healed,with an average healing time of 7 months.The mean extension-flexion arc of the injured wrists was between 106 degrees and 128 degrees.Three cases failed to heal,and two cases experienced deformed and sunken proximal scaphoid.Conclusions Common cortical bone screws can be easily changed into compression-like ones to treat old scaphoid fractures and result in satisfactory,clinic outcome.In addition,they are easily available,can be inserted through joint facet with limited negative effect on the joint,and play a double role of compression and fixation.

Objective To determine the correlation between the risk factors of cerebral palsy and gestational age of live born infants. MethodsThe gestational age, the risk factors of cerebral palsy and clinical features of 478 children with cerebral palsy were analyzed retrospectively. ResultsFetal distress, threatened abortion, non-infectious diseases during pregnancy, hypoxic-ischemic encephalopathy, neonatal convulsion, infection of newborn, intracranial hemorrhage and haemolysis did not correlated with the gestational age of children with cerebral palsy (P>0.05). Brain malformation, maternal infection, aspiration pneumonia, neonatal asphyxia and hyperbilirubinemia negatively correlated with the gestational age (P<0.05). The incidence of spasmo-diplegia was significantly different between preterm and term infant (P<0.05). ConclusionThe morbidity of cerebral palsy associated with the merging development malformation, maternal infection, aspiration pneumonia, neonatal asphyxia or hyperbilirubinemia increased as the gestational age declined. The spasmo-diplegia more happened in the preterm infants than in the term ones.

OBJECTIVE: To explore the applicability of integration between three-dimensional (3D) facial and dental data to evaluate the nasolabial morphology variation before and after the cross-arch fixed restoration of the maxillary implant-supported prostheses. METHODS: Twelve patients (4 women and 8 men), mean age (54.82±5.50) years (from 45 to 62 years) referred to the Department of Oral Implan-tology, Peking University School and Hospital of Stomatology, were selected and diagnosed with edentulous maxilla. For all the patients, 4 to 6 implants were inserted into the maxilla. Six months later, the final cross-arch fixed prostheses were delivered. The 3D facial images were collected before and after the final restoration. The 3D data of prostheses were also captured. All the 3D data were registered and measured in the same coordinate system. Then the displacement of all the landmarks [cheilion left (CHL), cheilion right (CHR), crista philtri left (CPHL), crista philtri right (CPHR), labrale supe-rius (LS), subnasale (SN), stomion (STO), upper incisor (UI), upper flange border of the prostheses (F-point, F)], and the variation of the distances between these landmarks (SN-LS, CPHR-CPHL, CHR-CHL, LS-STO) were analyzed and compared. RESULTS: The consistency test among three measurements of the length of F-SN indicated that the integration method of the dental prostheses and soft tissue had the good repetitiveness, ICC=0.983 (95%CI: 0.957-0.995). After wearing the final cross-arch maxillary implant-supported prostheses, all the landmarks on the soft tissue moved forward. The nasal base area changed minimally, and the shift of SN in the sagittal direction was only (0.61±0.44) mm. But the sagittal shift of LS was (3.12±1.38) mm. In the vertical direction, SN, LS, CPHL, and CPHR moved upward. But STO, CHL, and CHR moved downward a little. Except for the slight decrease of the length of philtrum (SN-LS), the length of CHL-CHR, CPHL-CPHR, and the height of upper lip were increased together (P < 0.01). In the direction of Z axis, the strong correlations were found not only between the movements of SN and F (r=0.904 3) but also between the movements of LS and UI (r=0.958 4). CONCLUSION The integration method of 3D facial and dental data showed good repetitiveness. And the strong correlations between the landmarks of prostheses and nasolabial soft tissue in the sagittal direction were found by this new method.
