Objective To discuss the variety of blood zinc,copper,iron,calcium level in children of lead poisoning Methods The stratified - random sampling method was used. Five hundred and forty children were selected in the urban areas, the rural areas and the islands. We examined blood lead level and other elements levels of these children, and analyzed the changes of these elements levels on condition of lead poisoning. Results The blood zinc level of children with lead poisoning was (4. 93 ? 1 12) mg/L, it was significantly lower than that of children without lead poisoning( t = 2.282 P

Objective To study the clinical feature and original diseases of bone marrow granulomas. Methods A total of 5217 bone marrow biopsies were retrospecitively analyzed in Peking Union Medical College Hospital from January 2001 to December 2007. Results Bone marrow granulomas were present in 20 cases, representing an incidence of 0.38% in the series and an annual incidence of 2. 9 cases per year. Finally, 13 of these cases (65%) were diagnosed with tuberculosis. Hematological neoplasms and viral hepatitis were found in 4 and 2 cases respectively. Acute interstitial nephritis was diagnosed in one case. Conclusions The finding of a granuloma in a bone marrow biopsy is not common and unspecific.Tuberculosis, hematological neoplasms and viral hepatitis are the most common underlying diseases. Bone marrow biopsy is an important method for the diagnosis of disseminated tuberculosis.

Objective To create the effective community-based day-care model of mental disability with multiple approaches. Methods 30 subjects with schizophrenia in Taoranting community in Beijing were selected in control group (n=15) and intervention group (n=15). A day-care multiple rehabilitation model had been implemented in the intervention group. They were evaluated with Positive and Negative Syndrome Scale (PANSS) and WHO Disability Assessment Schedule 2.0 (WHO-DAS 2.0). Results The scores of PANSS negative symp-tom, general psychopathological symptom and WHO-DAS 2.0 significantly reduced continually in the intervention group 8 and 12 weeks af-ter intervention (P<0.01). Conclusion Community-based day-care model can improve the rehabilitation of mental disabled people and inte-grate the community resources for the schizophrenics.

This study was undertaken to investigate mother-to-infant transmission of human parvovirus B19 and the significance of prevalence of B19 virus in abnormal fetuses in Guandong. The polymerase chain reaction (PCR)was established to detect parvovirus B19 DNA in 700 sera from 350 maternal-infant pair groups. The prevalence of B19 virus DNA was 1.14％ (4/350)and 0.28％(1/350)in the sera of pregnant women and cord blood of their neonates respectively. Parvovirus B19 DNA sequences were also detected in abnormal fetuses and new-born by PCR. The positive results were obtained in 5 samples of fetal tissues from 17 abnormal fetuses and in 3 those of neonatal tissues from 7 cases of neonatal death. The amplified products of PCR were identified to be the target DNA with Hae Ⅲ digestion. By in situ hybridization ,parvovirus DNA could be detected mainly in the nuclei of immature hematopoetic cells within fetal brain or spleen whose PCR tests were positive. The study results suggest that human parvovirus B19 infection does exist in maternal-infant transmission in Guangdong and might lead to harm on fetuses,but the prevalence rate of B19 virus may be very low. The evaluation of B19 virus infection might depend on reliable assay to determine present infection or past infection.

Objective To explore the diagnostic value of MRI on fetal congenital diaphragmatic hernia(CDH).Methods Fourteen pregnant women with gestation from 16 to 39 weeks were studied with a 1.5 T superconductive MR unit within 24 to 48 hours after ultrasound studies.Fast-imaging employing steady-state acquisition(FIESTA),single-shot fast spin echo(SSFSE)and T_1-weighted fast inversion recovery motion insensitive(FIRM)sequences were employed on the axial,coronal and sagittal planes of the fetal brain,thorax and abdomen,especially the thorax.Prenatal US and MR imaging findings were compared with postnatal diagnoses(13 fetuses)or autopsy(1 fetus).US,MR imaging and surgery were used for postnatal evaluation.Results Fourteen pregnant women(12 with a single fetus and 2 with twin fetuses)were studied.There were 12 fetuses(in 2 cases,being one of twins)with a left-sided and 2 with right-sided diaphragmatic hernias.For all cases,the prenatal MRI diagnosis Was correct when compared with postnatal diagnosis or autopsy.Two CDHs were missed and 2 were misdiagnosed by US.Intrathoracic herniated organs in 12 left CDH included the colon(n=1),the stomach(n=1),the bewel(n=5),or both the stomach and bowel(n=5).Intrathoracic herniated organs in 2 right CDH included the bowel(n=1),or the bowel and the right lobe of the liver(n=1).Conclusion Prenatal MRI is effective in the assessment of fetal congenital diaphragmatic hernia.

Objective To explore the diagnostic value of MRI on fetal congenital limb deformities.Methods Sixteen pregnant women,aged from 22 to 40 years (average 29 years) and with gestation from 22 to 39 weeks (average 29 weeks) were studied with a 1.5 T superconductive MR unit within 24 to 48 hours after ultrasound studies. Acquisitions consisted of coronal, sagittal, and axial slices relative to the fetal brain, spine, thorax, abdomen, especially limbs using 2D FIESTA sequences. Prenatal US and MR imaging findings were compared with postnatal diagnoses (4 fetuses) or autopsy (12 pregnant women,13 fetuses). Postnatal evaluation included US, MR imaging, computed tomography, and physical examination. Results Of the sixteen pregnant women (15 with a single fetus and 1 with twin fetuses) ,17 fetuses were found. Those limb deformities of sixteen pregnant women included congenital both upper extremities amelia (1 case), sirenomelia sequence (1 case), micmmelia (5 cases, 1 of which were twins),bilateral clenched hands (2 cases), right pelydactyly (1 case), simple right ectrodactyly (1 case), right dactylolysis(1 case), simple club foot (2 cases), hydrocele spinalis with club foot (2 cases), 1 of the 2 cases with bilateral clinodactyly. In 14 of 16 cases, the diagnoses established by MR imaging were correct when compared with postnatal diagnosis, and prenatal MR diagnosis was inaccurate in 2 cases. Conclusion Prenatal MRI is effective in the assessment of congenital limb deformities of fetuses, it can yield information additional to that obtained with US, and further correct US diagnosis.

Objective To explore the diagnostic value of MRI on fetal neural tube defects.Methods Ten pregnant women,aged from 25 to 35 years(average 28 years)and with gestation from 20-39 weeks(average 33 weeks)were studied with a 1.5 T superconductive MR unit within 24 to 48 hours after ultrasound(US)studies.The imaging protocol included fast-imaging employing steady-state acquisition,single-shot FSE and T_1-weighted fast inversion recovery motion insensitive sequences in the axial,frontal,and sagittal planes relative to the fetal brain,thorax,abdomen,and spines.Prenatal US and MRI findings were compared with postnatal MRI diagnoses(3 fetuses)or autopsy(7 fetuses).Results Ten pregnant women(9 with a single fetus and 1 with twin fetuses)were examined.For all cases,the diagnoses established by MRI were correct when compared with postnatal diagnosis or autopsy.In 7 cases,US and MRI findings were in complete agreement with postnatal diagnoses.US missed the diagnosis in 1 case and misdiagnosed in 2 cases.Ten neural tube defects in this study included anencephaly(1 case),exencephaly (1 case),meningoencephalocele associated with amniotic band sequence(1 case),meningocele(1 case),thoracic myelomeningocele(1 case),lumbar spinal bifida(1 case),sacroiliac myelomeningocele(2 cases),sacroiliac large cystic spinal meningocele(1 case),sacroiliac spinal bifida(1 case).Conclusions Prenatal MRI is effective in the assessment of fetal neural tube defects.It can exactly discriminate herniated contents and locate the spinal lesion level.
