Efficacy and safety of chemotherapy combined with interstitial (125)I seed implantation brachytherapy in unresectable stage IIIa/IIIb non-small cell lung cancer / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To compare the efficacy and toxicity of chemotherapy combined with insterstitial (125)I seed implantation brachytherapy in unresectable staged IIIa/IIIb non-small cell lung cancer.</p><p><b>METHODS</b>Seventy six patients with staged IIIa/IIIb non-small cell lung cancer were included in this study. Among them 37 cases were of the study group, treated with NP/GP scheme synchronization chemotherapy combined with (125)I seed implantation brachytherapy, while 39 cases in the control group were given NP/GP scheme chemotherapy. The cumulative survival time and median survival time of the two groups were compared by Kaplan-Meier analysis. The difference of mean survival time between the two groups was analyzed by log-rank method.</p><p><b>RESULTS</b>The study group and the control group achieved a total response rate of 56.8% and 30.8%, local control rate of 78.4% and 56.4%, respectively, showing a statistically significant difference (P < 0.05). The 1-year survival rates of the study group and control group were 66.7% and 45.3%, and the median survival times 15.4 and 11.5 months, respectively, with a significant difference between the 2 groups (P < 0.05). The total chemotherapy toxicity rate of the two groups showed no significant difference (P > 0.05).</p><p><b>CONCLUSION</b>The (125)I seed implantation brachytherapy combined with concurrent chemotherapy shows a low complication rate, acceptable toxicity, and good therapeutic effectiveness, and is an effective and satisfactory therapeutic modality in the management of locally advanced non-small cell lung cancer.</p>

Clinical characteristics of dyskinetic cerebral palsy / 中国康复理论与实践

@#ObjectiveTo study the risk factor, semeiology and neuroimaging abnormalities of dyskinetic cerebral palsy.MethodsA hospital-based study, 136 children with dyskinetic cerebral palsy were examined neurologically and their perinatal history was reviewed. Their cranial CT or MRI findings were studied. The association between the gestational ages, CP types and the radiological appearances were analyzed.Results124 cases (91.18%) were found obviously risk factors, including asphyxia (34 cases), pathological hyperbilirubinemia (70 cases), both asphyxia and hyperbilirubinemia (11 cases) and others (8 cases). According to the clinical and neurological features, 60 (44.12%) were chorea-athetoid cerebral palsy, 26 (19.12%) were dystonic cerebral palsy, and 50 (36.76%) were athetoid-spastic cerebral palsy. Those with asphyxia were mainly athetoid-spastic whereas cases with pathological hyperbilirubinemia were mainly chorea-athetoid cerebral palsy. The abnormal rates of cranial MRI scans was 52.9%, and it was higher in the group of asphyxia than pathological hyperbilirubinemia, preterm than term. The main findings on MRI scans were as follows: periventricular leucomalacia(PVL) 28 (38.8%), diffuse bilateral atrophy 20 (27.8%), focal abnormalities in the basal ganglia1 and/or temporal lobe 18 (24.0%).ConclusionMRI abnormalities of the brain were correlated with semeiologic subtypes, risk factors, and the gestational age at birth.

Magnetic resonance imaging findings in children with cerebral palsy / 中华儿科杂志

<p><b>OBJECTIVE</b>To study the clinical and neurological abnormalities in children with cerebral palsy (CP) and to attempt to correlate the types of CP and the gestational age at birth with radiological abnormalities detected by magnetic resonance imaging (MRI) of the brain.</p><p><b>METHODS</b>This is a hospital-based study, the subjects included 104 children with cerebral palsy who were hospitalized in the Qingdao Rehibilitation Center For Disabled Children. All the 104 hospitalized CP cases (47 with spastic diplegia, 9 with tetraplegia, 15 with hemiplegia, 22 with athetosis, and 11 with ataxia) were examined neurologically and their perinatal history was reviewed. Their cranial MRI findings were studied. The association between the gestational ages, CP types, and the radiological findings were studied.</p><p><b>RESULTS</b>The type distribution was significantly different between term- and preterm- infants. Spastic diplegia was the main type in preterm infants while hemiplegia and ataxia were mainly seen in term infants. MRI abnormalities were found in 88 of the 104 cases and abnormal rates of spastic diplegia, tetraplegia, hemiplegia, athetosis, and ataxia were 89.4%, 100%, 100%, 54.5% and 90.9%, respectively. There was no significant difference in abnormal rates between term and preterm groups. Thirty-one of 42 (73.8%) children with spastic diplegia had significant periventricular leukomalacia (PVL), which was more common among preterm-born children (90%). Of the 15 children with hemiplegia, 13 had unilateral lesions on neuroimaging. Spastic tetraplegia was associated with extensive, bilateral, diffuse brain damage. The abnormalities in term-born infants with athetoid cerebral palsy were mainly located in the basal ganglia region whereas the major abnormality in premature infants was PVL. Of the 11 children with ataxic cerebral palsy, 8 cases showed congenital cerebellum dysplasia on brain imaging.</p><p><b>CONCLUSIONS</b>Radiological abnormalities of the brain were correlated with CP types and the gestational age at birth; MRI scan was useful in revealing underlying brain abnormalities and speculating on the etiology of cerebral palsy.</p>

Analysis of 187 children with enteroviral central nervous system infection in Shandong area / 中华儿科杂志

<p><b>OBJECTIVE</b>To evaluate the diagnostic potential of previously published enterovirus (EV) reverse transcription polymerase chain reaction (RT-PCR) assay in detection of EV in CSF samples from children with a diagnosis of aseptic meningitis and to investigate the clinical characteristics of the patients seen in Shandong.</p><p><b>METHODS</b>EV RNA was detected in 187 CSF samples and serum and/or urine samples of a part of patients by RT-PCR and viral culture technique.</p><p><b>RESULTS</b>RT-PCR was positive in all 62 CSF specimens which were positive by cell culture (100%). In addition, 93 of 125 (74.4%) CSF samples negative by cell culture were RT-PCR positive. In 4 of these 93 (4.3%) patients, viral culture of specimens from other sites (serum or urine) was also positive. The sensitivity of CSF RT-PCR based on clinical diagnosis in patients with meningitis of negative bacterial culture results was 82.9% (155/187), which was considerably higher than the sensitivity of CSF virus culture 33.2% (62/187). The results of RT-PCR can be reported within 4 hours, whereas the viral culture of CSF requires 4.6 days for a cytopathic effect to develop. EV meningitis occurred in a sporadic form and in some areas there were outbreaks. The clinical characteristics of 155 patients with EV meningitis were different in different age groups.</p><p><b>CONCLUSION</b>EV was one of the most common causes of aseptic meningitis in Shandong area. The RT-PCR assay was rapid, sensitive and specific for the diagnosis of EV meningitis and may be a potential tests to shorten hospital stay and reduce the use of antibiotics.</p>
