ObjectiveTo explore the influence of 3C bolus wizard on postprandial glucose levels in diabetic patients. MethodFifty-eight patients with type 2 diabetes in our hospital were monitored with continuous glucose monitoring system(CGMS), continuous subcutaneous insulin infusion(CSII)and CareLink(3C for short)for 6 days.The function of “3C” bolus wizard was applied during treatment and all the patients were given dietary nursing and health education.The glucose level was observed.ResultThe level of P2hBG of the 58 patients was between 6.4~10.7mmol/L in 3~6 days.ConclusionsBolus wizard plays an important role in “3C” treatment.It can make the postprandial glucose of patients satisfactorily controlled in a short time only to avoid insulin hypoglycemia because of large doses of insulin.At the same time,health education on patients can achieve remarkable results as well.

Objective To report the functional reconstruction and rehabilitation for a patient who under- went allograft for both of his forearms and hands.Methods One male patient underwent allograft for both of his forearms and hands in October 2002 in our department to reconstruct his hand functions.The allografted hands were intervened with an integrated rehabilitation program,which involved administration of immunosuppressants,post- operative monitoring,postoperative functional training,massage,physiotherapy,orthosis,performance training, sensation training,secondary operation and mental rehabilitation.The patient was followed up for 4 years.Results The forearms and hands of the patient were in good shape and regained nearly normal sensation.The distance of two-point-discrimination was 2.5 cm to 4.0cm.The TAM (total active motion) of fingers was fine.The patient could look after himself well and were healthy in psychology.Conclusion An integrated rehabilitation program can yield satisfactory results in the management of allografted forearms and hands.

Aerenchyrna formation has been described in depth in a number of species at a histological level. But large gaps remain in our understanding of its regulation as a developmental process. It is attempted to analyse essential mineral elements like K, Mg, Cu, Zn, Ca and P in the cell wall of aerenchyma cells in petioles ofS. trifolia at five different developmental stages by CSEM-EDX technique. At early stage, K and Cl concentrations in cell wall were high up to 36% and 4.3% of dry weight, respectively. It supported the hypotheses that aerenchyma spaces are filled with liquid at early developmental stages of aerenchyma in S. trifolia petiole. Mg concentration was high at stage 2, up to 0.86% of dry weight. Zinc and Cu were detected only at rapid expansion stages, during which the concentrations were up to 1.5% and 2.5%, respectively. Calcium was detected in the cell wall only at mature stages, the concentration was high up to 1.3% of dry weight at stages 4 and 5. These results confirmed that the element concentration of aerenehyma cell wall undergoes dynamic changes during different developmental stages, and a low Ca with high Zn and Cu concentration are needed for cell expansion. Copper and Zn deposition in the cell wall showed a significant positive linear correlation, suggesting that these two elements share same or similar uptake and transport mechanism in plants.

Objective:China was categorized as one of the 68 countdown countries to achieve the United Nations Millennium Development Goals (MDG) 5. This paper aimed to analyze the situation of maternal survival, and coverage of proven cost effective interventions in China, where specific attention was paid to disparities. Methods: National maternal and child mortality surveillance data were used to estimate maternal mortality ratio (MMR). Coverage for proven interventions was analyzed based on National Health Services Survey, where experts' consultations were made for complementation. Results: There had been a significant reduction of MMR in China, however great disparities existed, with rural Ⅱ to Ⅳ areas experiencing 2 to 5 times higher maternal mortality risks than urban areas and accounting for over 70% maternal mortality burdens. Postpartum hemorrhage, pregnancy associated hypertension, embolism and sepsis were the leading causes, and over 75% of the maternal mortality was caused by preventable or curable causes. Maternal health services utilization decreased in accordance with region' s development level. Socioeconomic factors like financial difficulties were the main obstacles hindering access of care.Even those who made deliveries in hospitals faced different probabilities in receiving qualified care according to their socioeconomic standings. Conclusion: China is on track to achieve MDG 5, however great disparities exist. It is necessary to specifically target rural types Ⅱ to Ⅳ areas. Major causes of maternal mortality which can be prevented or averted through the provision of essential obstetrical care. Yet as compared with maternity health needs, insufficient coverage of maternal and child health (MCH) care services and poor service quality are the leading predisposing factors contributing to maternal mortality in China.

Objective To understand willingness of current medical undergraduates to work at community health-care service(CHS)institutions after their graduation to provides information for professional training for them.Methods Totally,2714 medical undergraduate students were recruited from three medical schools in east,middle and west China by multi-level sampling methods for questionnaire survey on their basic information and willingness to be employed at CHS institutions.results of the survey were described by relative numeric and tested by chi-square test for smtistical inference.Results About 60.6%of medical undergraduate students were willing to work at CHS organizations permanently or temporarily.Their willingness to work there differed with their native living areas and grades they were studying significantly(P＜0.01).Reason for those they would work at CHS organizations after graduation included work less stress and easier,and that for those reluctant to work there included low-income and lack of social respect for general practitioners.Conclusions Nowadays,few medical undergraduate students would like to work at CHS organizations after their graduation,which was influenced mainly by traditional ideas and concepts of employment,personal career devdopment,economic income,and so on.It is suggested that ideas of community work be strengthened for medical undergraduate students and their employment concepts be changed in the future.
