In recent years,successful pregnancies in renal transplant women have been reported worldwide.However,pregnancy in renal trasplant recipient is relatively rare in China.This paper reported a case of pregnancy 2 years post renal transplant.At the end of 28 weeks' gestation she had abnormal liver and renal function complicated with severe preeclampsia.Literatures were reviewed on considerations about pregnancy in renal transplant women.Maternal and neonatal outcomes can be improved by intensive care during pregnancy,proper immunosupression and timely termination of pregnancy.Abstract:SUMM ARY In recent years,successful pregnancies in renal transplantwomen have been reported world-wide.However,pregnancy in renal trasplant recipient is relatively rare in China.This paper reported a case of pregnancy 2 years post renal transplant.At the end of 28 weeks’gestation she had abnormal liver and renal function complicated with severe preeclampsia.Literatures were reviewed on considerations about pregnancy in renal transplantwomen.Maternal and neonatal outcomes can be improved by inten-sive care during pregnancy,proper immunosupression and timely term ination of pregnancy.

Objective:To explore the effect of intensified electrocardiogram (ECG) identification by using spectrogram for the monitoring and nursing ability of nurses who worked in department of cardiology.Methods: Monitoring and nursing capacity of 120 nurses of cardiology who had been trained on the intensified ECG identification by using spectrogram were researched by retrospective analysis. The 120 nurses were divided into control group (60 cases) and intervention group (60 cases) as the random number table. The nurses of control group only received routine training of ECG identification, while the nurses of intervention group received the training of using spectrogram for ECG identification on basic routine training of control group. A series of indicators, including the scores of ECG comprehensive application ability, identification ability of abnormal electrocardiogram, and the number of the identified abnormal malignance ECG and successfully treated patients, between the two groups were compared and analyzed.Results: After the training, the scores of basic theory, abilities of description and recording, and analysis ability in field operation of the intervention group were significantly higher than those of the control group, respectively (t=11.896,t=8.596,t=8.283,P<0.05). The identified ability including room speed, atrial flutter, ventricular flutter and other abnormal ECG of intervention group were significantly better than these of control group, respectively (x2=18.836,x2=17.698,x2=16.773,P<0.05). Besides, the discovery rate of abnormal malignance ECG (73.3%) and the successful rate of treatment (100.0%)of intervention group were significantly higher than that (31.7% and 81.7%) of control group, respectively (x2=19.184,x2=10.484,P<0.05). Conclusion:The training of intensified ECG identification by using spectrogram for nurse of cardiology can effectively enhance the capacities of identification for ECG and comprehensive application for nurses, and can faster confirm the situation of patient, and can contribute to achieve precision diagnosis for doctors.

Objective To study the effects of the early diagnosis and treatment of sleeve fractu re of patella in children.Methods The retrospection study was done to a nalyse the effects of the diagnosis a nd treatment of ten samples of sleeve fr acture of patella in our hospital fro m 1993to 2001.Results The diagnosis was confirmed by the characteristic s of the tension swelling of the knee,high position of the patella and a sle eve fractured fragment in the patella.T he operations were the main initial t reatment to regain the proper reduction.After 4weeksfixation the patients did knee exerc ises.And the curative effects were q uite good.Conclusion The sleeve fracture of the patella in children is easy to be misdiagnosed o r missed because of the cartilage.So it is the more important to be able to con duct an early diagnosis and treatmen t for the better prognosis.

OBJECTIVE： To determine the contents of puerarin in Qingshangqitong capsule.METHODS： TLC was used with detecting wavelength 260nm and reference wavelength 370nm.RESULTS： The average recovery was 98.43％ with a RSD of 1.45％ .CONCLUSION： This method is simple and accurate,and can be used as a quality control parameter of this preparation.

SUMMARY In recent years, successful pregnancies in renal transplant women have been reported worldwide. However, pregnancy in renal trasplant recipient is relatively rare in China. This paper reported a case of pregnancy 2 years post renal transplant. At the end of 28 weeks' gestation she had abnormal liver and renal function complicated with severe preeclampsia. Literatures were reviewed on considerations about pregnancy in renal transplant women. Maternal and neonatal outcomes can be improved by intensive care during pregnancy, proper immunosupression and timely termination of pregnancy.

Thrombocytopenia caused by chemotherapy and radiotherapy has become a very important factor that influence the treating of malignant tumors. Traditional Chinese medicine has a good curative effect in its prevention and treatment. Animal experiment also proved the curative effect and some of the traditional Chinese medicine's function mechanism. We introduced the animal model, the state of field and development of the thrombocytopenia caused by chemotherapy and radiotherapy.

It is necessary to have a research on dental fluorosis in a population to minimize the prevalence and severity of caries.It is important to research the pathogenesis of enamel fluorosis and prevention and control of dental fluorosis and caries.This article reviews the progress in chemistry and biology of dental fluorosis.

Objective To explore the clinical value of multi-slice CT in distinguishing between benign parotid tumors and malignant parotid tumors. Methods CT scanning images of 72 parotid tumor patients were analyzed. The location, shape, density, edge, cystic necrosis and degree of enhancement of the tumors were analyzed, de-gree of cervical lymph node swelling were analyzed, and all the analysis results were compared to pathological re-sults. Results 80 lesions were diagnosed in tumors, among which 59(73. 8%) lesions were benign tumors and 21 (26. 2%) lesions were malignant tumors. The CT images of benign tumors showed that 42(71. 2%) of them were located in the superficial lobe and with regular shape and uniform density;62.7% of them had clear edge;57 . 6%of them showed mild or moderate enhancement. 2 cases of benign tumors presented cervical lymph node swelling, which were proved to be pathological inflammatory mass after operation. Whereas in the CT images of malignant tumors 12( 57. 1%) of them were located in the deep lobe or in both of the superficial lobe and the deep lobe. 15 (71. 4%) of them had irregular shape and uneven density. 81% of them had unclear edge. 71. 4% of malignant tumors were significantly enhanced. 9 cases of malignant tumor were with cervical lymph node metastasis. There was statistical difference between the shape, edge, density, cystic necrosis, degree of enhancement and cervical lymph node metastasis of the two groups of tumors(P<0.05), while the location and the degree of enhancement of the two groups of tumors showed no statistical difference ( P>0.05 ) . Conclusion Most of benign and malignant parotid tumors can be correctly diagnosed by analyzing multi-slice CT images.
