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.

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.

Objective To evaluate the effect of procaine on prevention of skin slap necrosis after modified radical mastectomy in breast cancer.Methods 106 breast cancer patients were randomly divided into treatment and control groups.In the treatment group,procaine(1% 100ml diluted in 300ml mormal saline,42℃)were compressed under the skin flap in operation,the control group received same amount of normal salin instead.The rates and sizes of skin flap necrosis were obeserved and compared.Results There were 13 cases suffured from skin flap necrosis among 106 breast cancer cases who received surgery operation.The rate of the flap necrosis in treatment group was5.76%(3/52),and the control group was 18.51%(10/54),there was significant difference(P

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 effect of ca se-teaching applied to the classes of practical training of parasitology. Methods The case-teaching was tentatively performed in a part of the undergraduates in our school during their parasitology practical training classe s.Results The effect of case-teaching was obviously superior t o the traditional one. The total scores,the theory examination and the specimen recognition scores were all higher in the class which employed the case-teachin g than in the control ones (P

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.

Aim The effect of tetrandrine on TGF-?1 mRNA expression in glomerulosclerosis rat was observed. Methods The rats were randomly divided into four groups, such as the normal control group (sham operative rat), glomerulosclerosis model group,tetrandrine group and amlodipine group. The expression of TGF-?1 mRNA was analyzed by Northern blot hybridization. Results The expressions of TGF-?1 mRNA in two treating groups were much lower than untreated model group. There were no difference between these two treating groups. Conclusion Tetrandrine can decrease the expression of TGF-?1 mRNA in glomerulosclerosis rat induced by unilateral renctomy plus adriamycin.

OBJECTIVE:
To observe the expression of discs large homolog 4 (DLG4) protein in hippocampus, amygdala and frontal cortex of rats and evaluate postsynaptic density in heroin dependence.
METHODS:
The rat heroin dependent model was established by increasing intraperitoneal injection of heroin. DLG4 proteins in hippocampus, amygdala and frontal cortex of heroin dependent 9, 18, 36 days rats were detected with immunohistochemical staining and compared with that in the control group.
RESULTS:
DLG4 proteins in hippocampus, amygdala and frontal cortex were gradually reduced with extension of heroin dependent time.
CONCLUSION
Heroin dependence can affect postsynaptic density of hippocampus, amygdala and frontal cortex. The changes become more apparent with extension of heroin dependence time.
