Journal of Chongqing Medical University 1987;0(01):-
We established a new method, the E-ELISA, to detect red-cell immune adherence (RCIA) activity and the value of immune complexes on the surface of red cell. This method has a good specificity, reproducibility and easily perform, with a sensitivity of 31.25ng/100ul. Fifty samples from normal human were determined. The RCIA activity was 5445 (3.73 ? 0.22 LgG,ngAHG/10~7RBC and the value of immune complexes on the surface of red cell was 234.7(2.37 + 0.21LgG)ngAHG/10~7RB C. We likely suggest that this method is a good tool for study of immune fanction of erythrocytes

Chinese Journal of Tissue Engineering Research 2001;5(23):144-145
Objective To investigate the different effects of clozapine and risperidone on levels of blood glucose in patients with schizophrenia. Method 200 qualified cases selected from psychiatric department were divided into two groups randomly, of which 100 cases accepted the treatment with clozapine and the other 100 cases with risperidone. Blood glucose tests were used before treatment ,4 weeks after treatment and 8 weeks after treatment Results There was significantly higher blood glucose level in clozapine- treated group than in risperidone- treated group after 4 or 8 weeks treatment. The number of cases who had elevated blood glucose level (>6.1 mmol/L) in clozapine- treated group was significantly more than in risperidone- treated group. Conclusion The glucoregulatory abnormality which leads to glucose elevation in clozapine- treated patients is greater than in risperidone- treated patients. Additional motivation to clinical monitor for antipsychotic treatment- related hyperglycemia is indicated.

Chinese Journal of Internal Medicine 2011;50(1):32-35
Objective To evaluate the cerebrovascular reserve(CVR) in patients of ischemic stroke with cerebrovascular stenosis by Xenon-enhanced CT. Methods Twenty subjects of ischemic stroke with cerebrovascular stenosis were recruited. All subjects were examined by Xenon-enhanced CT before and after acetazolamide (ACZ) challenge test to quantitatively measure the regional cerebral blood flow (rCBF) and CVR. Results We compared the rCBF in the corresponding region supplied with stenosed artery (divided manually) with that in the region of normal side. There was no significant difference in resting rCBF but in CVR [ipsilateral side vs. normal side ( 5.9 ± 24. 3 ) % vs ( 25.9 ± 32. 6 ) % , P < 0. 05]. Conclusion Impaired CVR is an important character of the patients with cerebrovascular stenosis suffered from ischemic stroke.

Objective To explore the prenatal ultrasonographic features of fetuses diagnosed as echogenic bowel and chromosomal abnormalities. Methods From September 2009 to June 2013, eighty cases diagnosed as echogenic bowel by prenatal ultrasound screening in our hospitals underwent chromosomal karyotype analysis and were followed up till fetal birth. The prenatal ultrasonographic features were carefully correlated with the postnatal findings. Results Prenatal ultrasoundand chromosomal findings of the 80 cases were:(1) Fifty-eight cases of fetuses with echogenic bowel alone (72.5%, 58/80, without chromosomal karyotype abnormalities). (2) Eleven cases of fetuses with additional ultrasound soft markers (13.8%, 11/80, without chromosomal karyotype abnormalities). The ultrasound examination revealed 8 cases of choroid plexus cysts, 1 case of single umbilical artery, 1 case of shorter nasal bone, and 1 case of echogenic intracardiac focus. (3) Five cases of fetuses with severe functional abnormalities or complex structural malformations and normal chromosomal karyotype. The ultrasound examination revealed 3 cases of structural cardiac malformations, 1 case of heart failure and 2 cases of central nervous system malformations. Of them,one case showed complex malformations (right ventricular dysplasia syndrome, cerebellar dysplasia and single umbilical artery), whereas the remaining 4 cases only involve single malformation. (4)Six cases had chromosomal abnormalities (7.5%, 6/80), including 3 cases of abnormal chromosome microdeletions, and 3 cases of abnormal chromosome numbers (1 21-trisomy syndrome, 1 18-trisomy syndrome, and 1 triploid syndrome). All of them had severe structural malformations and abnormal soft markers. The ultrasound examination revealed 2 cases of severe cardiac malformations, 2 cases of central nervous system malformations, 1 case of pericardial/peritoneal effusion, and 1 case of placental chorionic multiple hemangioma. One case of holoprosencephaly (donor of the twins) ended with intrauterine death. The associated abnormal soft markers include nuchal fold (NF) thickening, choroid plexus cysts, umbilical cord cysts, single umbilical artery, and placental chorionic hemangioma. Conclusions The fetuses with echogenic bowelaloneusualyhaveagoodprognosis.Insomecases,echogenicbowelmaydisappearduringvfolow-up.The fetuses complicated with severe structural malformations and chromosomal abnormalities have poor prognosis. For the fetuses diagnosed of echogenic bowel by prenatal ultrasound screening, systematic ultrasound examination should be carried out and clinical chromosomal karyotype analysis was suggested.

Purpose:To evaluate the protection of astragalus injection for Doxorubicin (adriamycin)-associated cardiotoxicity. Methods:58 patients were randomized into two groups for this clinical trial. 30 patients were in the test group ,and 28 in control group. Patients in the test group received astragalus injection in 5% glucose solution once every day for two weeks starting three days before adriamycin-based chemotherapy. 28 patients in the control group began to receive oral vitamin E 100 mg twice a day and coenzyme Q10 20 mg three times a day for two weeks. Chemotherapy is the same as that in the test group. Electrocardiogram (ECG) and echocardiogram were employed to evaluate the cardiac function. Results:There was a substantial difference in ejection fracton between the two groups,but the difference was not statistically significant. Statistically significant differences were observed in the two groups with regard to all other parameters,including abnormal changes in ECG and LVIDD、LVISD、A/E、FS. Conclusions:Astragalus injection is a good drug which can prevent the occurrence of acute cardiotoxicity associated with adriamycin. It can also reduce the occurrence of chronic cardiotoxicity.
