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.

Objective To evaluate the clinical outcome of a method of renconstruction of Type Ⅱb defect of thumb both and reserving the length of the donor toe.Methods From March 2012 to Febrary 2014,there were 11 cases of thumb defect treated in our hospital.According to Gu Yudong's classification,all were type Ⅱ b.Three were open defect and others were closed defect.All were treated with combined transfer of big toe wrap-around flap and autogenous iliac graft for thumb reconstruction while a superficial circumflex iliac artery perforator flap was used to resurface the donor defect.The donor site of the belly was sutured directly.Results All of the reconstructed thumb survived.Among 11 flaps,arterial crisis occurrred in 1 case,venous crisis occurred in 2 cases,and all survived after operative treatment.The patients were followed-up from 3 mooths to 15 months,all the thumbs had a good appearance.The thumb opposition function was good and sensation recovery to S3 + and two-point discrimination from 6-8 mm.The donor big-toe was preserved.All the flaps had satisfactory color and texture,but looked a little plump.All the patients had no effect on walking and running.Four flaps had more beautiful appearance after flap plastic.There was only one linear scar on the belly donor without any discomfort.Conclusion It is an effective method of combined transfer of big toe wrap-around flap and autogenous iliac graft while a superficial circumflex iliac artery perforator flap was used to resurface the donor defect used to reconstrucution of Type Ⅱ b defect of thumb is very good.

Objective To explore the value of MRI on fetal autosomal recessive polycystic kidney disease (ARPKD).Methods Sixteen pregnant women,aged from 28 to 38 years (average 30 years) and with gestation age from 22 to 36 weeks (average 25 weeks) underwent MR scanning with a 1.5 T MR unit within 24 to 48 hours after ultrasound examinations.The imaging sequences included steady-state free-precession (SSFP) sequence,single-shot turbo spin echo (SSTSE) sequence and T1-weighted fast imaging sequence.Prenatal US and MR imaging findings were compared with autopsy or pathological results.Results A total of 16 cases of ARPKD showed bilateral markedly enlarged kidneys and diffuse high signal small cysts in renal medulla on SSTSE sequence.Among the 16 cases,11 cases were with oligohydramnios,1 1 cases were with pulmonary hypoplasia,and 6 cases were with hepatic fibrosis.Eleven cases of pulmonary hypoplasia and 6 cases of hepatic fibrosis were all missed by US.For the diagnosis of the renal anomalies,US missed one case.MRI diagnosis was correct in all these cases.Conclusions MRI shows great advantages on the diagnosis of fetal ARPKD,and it is not affected by the amount of amniotic fluid.It can be used to evaluate kidney and lung abnormalities accurately.

BACKGROUND:Methods after mechanical stimulation can be combined with various kinds of cells to produce many conversion types so as to start the various physiological functions of the body. OBJECTIVE:To analysis the reason why rol ing massage can improve the intracellular concentration of Ca2+METHODS:A biodynamic experimental device was set up, composed of pressure generating device, pressure forming device, pressure display device and related data recording device. We detected the effects of rol ing massage on Ca . 2+concentration in normal skeletal muscle cells and damaged cells through the different functions of the experimental device and system software. These functions consisted of pressure display, data transmission and recording, signal acquisition and processing, pressure signal acquisition, control and processing of signal acquisition, wireless signal transmission and receiving system, display system, storage system, system implementation function. RESULTS AND CONCLUSION:The experiment results showed that rol ing massage could reduce the Ca 2+concentration in the normal skeletal muscle cells and damaged cells. These findings suggest that rol ing massage can improve the overload of intracellular Ca2+in damaged cells, and it is superior to the sinusoidal mechanical stimulus.

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.
