Objective To research the clinical value of serum thyroid peroxidase (TPOAb) in screening thyroid dysfunction in pregnancy.Methods The concentration of serum TPOAb and TSH(thyroid-stimulating hormone) was detected by MEIA and CMIA in 75 cases of pregnant women with thyroid disfunction,and 145 cases of pregnant women without tyhroid dysfunction (as control group).Results There were significant differences in both TSH and TPOAb levels between pregnant women with and without thyroid dysfunction(P0.05). So the normal serum TSH could not completely exclude the thyroid dysfunction in pregnant women.Conclusion TPOAb can be used as a prenatal screening marker for early diagnosis of thyroid dysfunction in pregnancy. From the diagnostic point, TSH can not completely substitute for TPOAb and the abnormal TPOAb can indicate the possibility and risk for autoimmune thyroid disease in pregnant women.

We applied a new teaching mode,combining problem-based learning (PBL) with extended teaching in clinical internship and case discussion,in order to adapt to the new situation in infectious diseases.The teaching efficacy was evaluated by questionnaire and classroom effect.The results showed that the new mode cultivated the students' self-learning ability and broadened their professional perspective.

Objective To assess the left ventricular(LV)segmental function by velocity vector imaging(VVI)in uremic patients with diffferent quantity of parathyroid hormone(PTH).Methods Sixty patients with uremia were divided into 2 groups according to the value of PTH:group A with PTH less than 3 times of upper normal limit,group B with PTH more than 3 times of upper normal limit.Normal control group was 30 healthy subj ects.All people were evaluated by VVI.The parameters,including the longitudinal systolic strain rate(SSR),diastolic strain rate(DSR),were analysed among the three groups.Results Compared with normal group,in group A and B,SSR,DSR in all segments were lower.Compared with group A,in group B,DSR were all significantly lower(P＜0.05),SSR in apex of laternal wall,medium of anterior septum wall,posterior wall,medium and apex of posterior septum wall and superior wall,base,medium and apex of anterior wall were significantly lower(P＜0.05).There was no statistically significant difference of left ventricular ejection fraction between the two groups(P＞0.05).Conclusions VVI is a viable objective tool to quantitatively assess LV segmental function damaged by different quantity of PTH.

Hepatitis c virus (HCV) infection has become one of the global public health problem,while there is no vaccine to prevent HCV infection, the so-called "cocktail" therapy that use a combination of drugs targeting multiple steps in the HCV infection cycle could achieve better curative effect. the process of HCV entering into host cell is the important step of drug intervention, in which HCV envelope protein El and E2, Host cell factors including Heparan sulfate(HS), CD81, scavenger receptor class B type I (SR-BI), Occludin (OCLD), Claudin (CLDN), low densitity lipoprotein receptor (LDLR), dendritic cell-specific ICAM-3-grabbing nonintegrin (DC-SIGN), Liver/lymph node specific ICAM-3-grabbing integrin(L-SIGN), trans- ferrin receptor 1 (TfR1) and so on play a important role. The virus and the host factors can be used as targets of hcv entry inhibitors many studies have shown that as novel and promising compounds, HCV entry inhibitors combinating with other drugs can be more effective in the treatment of HCV, this paper have re- viewed targets and inhibitors of HCV enterring into host cell since 1990s.

Conclusions The formation of the core competence evaluation index system for new nurses is scientific and reliable, which can provide objected and quantitative standards for assessment, training and evaluation of new nurses.

Objective To breed homozygous mice of Treg-Th17 fluorescence double labeling and to investigate the role of Treg-Th17 balance in endotoxemia. Methods Mice of Treg and Th17 fluorescence single labeling were brought from Harvard Medical School,USA and were mated and bred based on the genetic rules.The genomic DNA was extracted from the tails of second generation weaning mice for genotyping by polymerase chain reaction (PCR).Thereafter,the homozygous mice of fluorescence double labeling were selected to have successive inbreeding for three generations and their genotypes and growth status were measured.The endotoxemia model in vivo was duplicated and changes of Treg-Th17 balance were detected by flow cytometry analysis at 24 h and 48 h after endotoxemia. Results Among the seven second generation mice in the first batch,only three (two males and one female) were the wanted homozygotes.Meanwhile,the genotypes of their offsprings for the next three generations were all Foxp3 RFPKI-homo IL-17A GFPKI with normal growing status.As important component of endotoxin,lipopolysaccharide (LPS)could induce significant signal expressions of red fluorescence protein (RFP) and green fluorescence protein (GFP).The ratio of CD8a + Foxp3 +,CD8a + IL-17A +,CD4 + Foxp3 + and CD4 + IL-17A + in the lymphocytes went up significantly in the group of 24 hours of LPS treatment,as compared with the control group (P ＜ 0.01 or P ＜ 0.05 ),while the difference between the control group and the group of 48hours of LPS treatment had no statistical significance (P ＞ 0.05). Conclusion Foxp3 RFPKI-homoIL-17A GFPKI mice have identical genotypes and stable genetic characteristics and is a model animal and novel research platform that can provide real-time monitoring of the changes of Treg-Th17 balance in vivo.The role of T reg-Th17 balance works significantly at 48 hous after the subject is exposed to LPS stimulation,and the roles of CD8a + Foxp3 and CD8a + IL-17A + in Treg-Th17 balance require further investigation.

Objective To study the efficacy and safety of Gonadotropin-releasing hormone agonists (GnRH-a) combined with laparoscope conservative surgery in treatment of moderate or severe endometriosis.Methods From Jan.2007 to Jan.2010,68 patients with moderate or severe undergoing treatment in Renmin Hospital of Wuhan University were enrolled in this retrospective study.Three groups were classified,which were 25 patients in GnRH-a group,subcutaneous injection Leuprorelin on the second day of menstruation,every 4 weeks for 3 months.Twenty-three patients in Marvelon group,orally one marvelon tablet on the second day of menstruation,continuous 21 days for one period of treatment for 3 courses.Twenty patients in surgery group,without any medicine used preoperatively.All patients were followed by 12 months and compare their surgery time,blood loss,recovery,visual analog scale (VAS),and recurrence and so on.Results The operating time were (68 ± 18) min in GnRH-a group,(80 ± 21) min in Marvelon group and (90± 24) min in surgery group.The amount of bleeding were (118 ± 15) ml in GnRh-a group,(161 ± 18) ml in Marvelon group and (193 ± 13) ml in surgery group.There was significant lower in the operating time and amount of bleeding in GnRH-a group than those in other two groups (P ＜ 0.05).The activity time and the anus exhaust time were shorter in patients in GnRh-a group than those in the other two groups significantly(P ＜ 0.05).When followed up in 12 months after treatment,visual analogue scale had dropped from 3.8 (1.9-6.8) to 1.9 (1.1-2.8) in GnRh-a group,from 2.7 (1.3-5.5) to 1.8 (1.2-3.2) in Marvelon group and from 1.9(1.0-4.9) to 1.6(1.0-3.6) in surgery group.It was showed the most remarkable decreased VAS in GnRHa group when compared with the other two groups(P ＜ 0.05).The recurrence rates were 12％ (3/25) in GnRH-a group,22％ (5/23) in Marvelon group and 25 ％ (5/25) in surgery group.It was found that the most significant lower recurrence was in GnRH-a group when compared with the other two groups (P ＜ 0.05).Conclusions It was safe and efficacy that GnRH-a combined with laparoscopic conservative surgery were used in treatment of endometriosis.It could bring shorter operation time,less intraoperative blood loss,quick postoperative recover,the lower recurrence rate.
