Hypothyroidism is one of the most common endocrine disorders in childbearing or pregnant women.Gestational hypothyroidism can increase the incidence rate of the variety of pregnancy complications and adverse pregnancy outcome.It also can make adverse effects on the fetus and neonate,such as death,placental abruption,fetal malformation,intrauterine growth retardation and preterm,low birth weight,neonatal respiratory distress syndrome,it can also cause abnormal thyroid function of neonate,severely can cause nerve,mental,physical and mental developmental abnormalities and even death.Therefore,it is recommended that childbearing women who are at high risk for pregnancy should strengthen to monitor pregnancy thyroid function and treat as soon as possible in order to reduce the adverse effects on offspring.

OBJECTIVE: To evaluate the current situation and trend of narcotic drug use in our hospital where the authors work in order to provide the reference for scientific management and rational use of these drugs. METHODS: The yearly amount of narcotic drugs administered in the whole hospital, the yearly amount in the separate departments, as well as drug expenditures and ratios between January 2002 and November 2005 were added up and analyzed statistically. RESULTS: The amount of bucinnazine use dominated in the first. The amount of morphine for oral use was increasing year by year. The amount of fentangl transdernal patch use was also bigger and increasing rapidly. However, the amount of pethidine and morphine for injection use was decreasing. CONCLUSION:Analgetics for oral and transdermal use will be the main categories of analgetics in the future.

Objective To study the T Lymphocyte Subsets and the cytokines in the newborns with infectious diseases. Methods Twenty cases of neonatal bacterial pneumonia (bacterial group), 15 cases of rotavirus enteritis (virus group) and 20 newborns with jaundice (control group) were recruited in this study. The peripheral CD4+T Cells and lymphocyte subsets were assessed by flow cytometry. Results The IL-4 level was significantly different among different groups (F=3.39, P=0.041). The levels of IL-17 and IFN-γdid not differ signiifcantly among different groups (F=0.28 and 1.24 respectively, P>0.05). The IL-4 level was higher in bacterial group than that in virus group and control group (P<0.05). The percentages of CD3+, CD4+, CD19+and NK cells and the ratio of CD4+/CD8+ had significant difference among different groups (F=3.30-26.69, P<0.05). The percentages of CD3+and CD4+cells and the ratio of CD4+/CD8+were lower in bacterial group and virus group than those in control group (P<0.05). The percentage of CD19+cells was higher in bacterial group and virus group than that in control group (P<0.05). The percentage of NK cells was lower in virus group than that in bacterial group and control group (P<0.05). Conclusions The pattern of cytokines level is different in newborns with infection caused by different pathogens. Newborns with infectious diseases have immune dysfunction and Th2-dominated imbalance. The low percentages of T lymphocyte subsets indicate the depressed cellular immunity after infection, which may result in atypical symptom and prolonged disease course.

Objective To investigate the application of numerical simulation technique in supraorbital and frontal osseous defect.Methods The data of the patients with complex supraorbital and frontal osseous defects were obtained by helix CT scan.Numerical model based on the data was built up by computer.And the true model was produced by Rapid Prototyping.Being stimulated before this operation.the model was directly used in the operation.Results All of these 12 patients(one of defect of brow,four fracture of brow and zygoma,seven of old fracture of brow and zygoma)in this study were satisfied and their brows were symmetry after operation.All of them were satisfied after 1 or 2 years,without implantation exposure and transfiguration except one with infection.Conclusion Based on numerical technique difficulties of repairing,complex supraorbital and frontal osseous defect could be resolved by such process as collecting the bone data,stimulating operation by true models,and producing implantation before the operation.The accuracy of these operations can be improved.
