Chinese Journal of Radiology 2001;0(02):-
Objective To evaluate the feasibilities of the potential donors in liver cell transplantation using the human fetal hepatocytes and immortalized L-02 hepatocytes by comparing their biological features. Methods Human fetal hepatocytes were isolated from aborted fetal livers (gestational ages from 14 w to 24 w) by an improved two-stage perfusion method and cultured in a conditioned medium without any growth factors.?-fetal protein (AFP) and albumin (ALB) were detected by radioimmunoassay (RIA) and cytokeratin-19 (CK-19) was identified by cellular immunochemistry study.Immortalized L-02 hepatocytes were cultured in the same condition and the characteristic proteins were detected by the same methods.Results The viability of human fetal hepatocytes was approximately 95% using the perfusion method, and the maximum survival time of the cultured hepatocytes was 3 weeks.The expression of AFP, ALB, and CK19 was detected at the same time, especially during Day 3 to Day 7 in the culture.By comparison, the proliferation ability of L-02 hepatocyte was greater, although with a lower level of ALB secretion.The expression of AFP and CK19 was not detected.Furthermore, during the long culture, L-02 hepatocytes may undergo a morphologic change and fail to express ALB.Conclusion Human fetal hepatocyte may be a practical donor for hepatocyte transplantation with its high-level protein expression and potential bi-differentiation ability.In view of the absent expression of ALB and the morphologic change in culture, although with better proliferation, L-02 hepatocyte seems not useful for hepatocyte transplantation.

Objective To evaluate the association between maternal thyroid diseases in the first trimester of pregnancy and obstetric complications.Methods A total of 2 517 pregnant women from 10 hospitals in Shenyang during the first 12 weeks of gestation were enrolled in this study.All sera obtained from pregnant women were measured for thyroid-stimulating hormone (TSH),free thyroxine ( FT4 ),and thyroid peroxidase antibody (TPOAb).Collected items include obstetric outcomes and complications.Results Serum TSH above 2.5 mlU/L during the first trimester of pregnancy increased the rate of spontaneous abortion ( 8.69% vs 6.38%,P =0.048 ),even if subclinical hypothyroidism (9.50% vs 6.38%,P =0.009).TSH above the gestational special reference range,passive smoking,and over 30 years were independent factors for increasing the rate of spontaneous abortion.Hyperthyroidism and hypothyroidism with drug treatment to maintain normal thyroid function during pregnancy reduced the incidence of spontaneous abortion.Increased or decreased levels of serum TSH and TPOAb(+) were not related with other obstetric complications.Conclusion Serum TSH above the gestational special reference range during the first trimester of pregnancy is a risk factor of spontaneous abortion; maintaining TSH within the normal range by treating hyperthyroidism or hypothyroidism may reduce spontaneous abortion rate.

Data were collected through questionnaire from 505 women enrolled during early pregnancy.Based on soy intake frequency,the subjects were divided into three groups:frequent (three or more times per week),conventional ( more than twice per month but less than three times per week),and occasional ( two or fewer times per month).Serum TSH and FT4 were measured by chemiluminescence immunoassay.The urinary concentrations of two primary isoflavones (daidzein and genistein) and creatinine were further assessed in 95 subjects from the three groups.The percentages of frequent,conventional,and occasional consumers were 18.6%,62.6%,and 18.8%,respectively.No difference was found in age,medical records,family history of thyroid diseases,serum FT4,TSH,and prevalence of thyroid dysfunctions among three groups. Both urinary daidzein and genistein levels were significantly higher in the frequent consumers compared with the other two groups.No correlations were found between urinary isoflavone levels and serum FT4 or TSH.These findings suggest that dietary soy consumption during early pregnancy seems not to be associated with the development of thyroid dysfunction.

Objective To investigate the changes and related factors of maternal thyroid autoantibodies during early pregnancy. Methods Urinary iodine concentration( UIC) , serum thyroid stimulating hormone( TSH) , free thyroxine ( FT4 ) , thyroid-peroxidase antibody ( TPOAb ) , thyroglobulin antibody ( TgAb ) concentrations were determined in 7 190 women during early pregnancy in an iodine-sufficient region of China. Results The prevalence of TPOAb positivity and TgAb positivity were 8. 7% and 12. 0% respectively. The prevalence of overt hypothyroidism and subclinical hypothyroidism increased significantly in group of thyroid antibody positivity. The prevalence of TPOAb positivity and TgAb positivity presented a U-shaped curve, ranging from mild iodine deficiency to iodine excess, especially increased significantly in the group with UIC<100 μg/L. Conclusion Prevalence of thyroid antibodies positivity became higher during early pregnancy. The positive thyroid autoantibodies during pregnancy were significantly associated with maternal hypothyroidism. Both iodine excess and iodine deficiency are risk factors of positive thyroid antibodies.

Objective To study the effect of maternal subclinical thyroid abnormalities [including subclinical hypothyroidism, hypothyroxinemia and positive anti-thyroid peroxidase antibody (TPOAb) with normal thyroid function] in women during 16-20 weeks of gestation on offspfing's intellectual development and motor function. Methods Sera from 1 268 women during 16-20 weeks of gestation (collected 2 years ago) were obtained and thyroid stimulating hormone (TSH), total thyroxine (TT4), free thyroxine (FT4) and TPOAb levels were measured. Pregnant specific thyroid function reference ranges were used to screen for subclinical hypothyroidism (18 cases), hypothyroxinemia (19 cases) and positive TPOAb (34 cases). From the same cohort, a total of 142 pregnant women who were euthyroid with negative TPOAb were selected as controls (a case: control ratio of 1 : 2). Intellectual and motor development score evaluations were performed in their children at 25-30 months of age. Results In the group of pregnant women with subclinical hypothyroidism, the offspring' s intelligence score was (109.89±13.81) points, which was 8.88 points lower than in the control group (P < 0.01). Similarly, the motor score of the offspring was (108.11±9.93) points, which was 9.98 points lower than in the control group (P < 0.01). In the pregnant women with hypothyroxinemia, the offspring's intelligence score was (112.32±15.10) points, 9.30 points lower than in the control group (P <0.01); the motor score was (112.21±12.26) points, 7.57 points lower than in the control group (P < 0.01). In the pregnant women with positive TPOAb and euthyroid function, the offspring's intelligence score was (112.70±20.64) points, 10.56 points lower than in the control group (P < 0.01); the motor score was (110.64±12.49) points, 9.03 points lower than in the control group (P < 0.01). Conclusion Maternal subclinical thyroid abnormality between 16-20 weeks of gestation adversely may affect offspring intellectual and motor development, suggesting the necessity for screening and treatment of maternal subclinical thyroid abnormality in the early stages of pregnancy.

OBJECTIVE:To provide reference for rational use of Clindamycin hydrochloride injection. METHODS:The utilization of Clindamycin hydrochloride injection in orthopedic inpatients of a third grade class A general hospital dur-ing 2013-2015 was analyzed and investigated retrospectively. The rationality evaluation standard was formulated to evaluate the rationality of drug use in those patients. RESULTS:A total of 189 orthopedic inpatients received Clindamycin hydro-chloride injection,and there were 152 cases of irrational drug use among which there were 16 cases of irrational therapeu-tic drug use and 136 cases of irrational prophylactic drug use. Irrational drug use mainly included irrational usage and dos-age(86.18%),irrational drug selection(44.74%)and irrational drug replacement(15.79%). Two patients suffered from ADE,i.e. rash and nausea. After drug withdrawal and symptomatic treatment,the symptoms were improved,but irrational drug use was found in one case. CONCLUSIONS:The utilization of Clindamycin hydrochloride injection is irrational in or-thopedic department. It is necessary to further standardize medication behavior and guarantee the safety and effectiveness of drug use.
