To explore the significance of hypothyroidism and subclinical hypothyroidism screening in pregnancy.A total of 278 pregnant women were divided into three groups of clinical hypothyroidism (n =36),subclinical hypothyroidism (n =103) and normal control (n =139).Their clinical profiles,pregnancy outcomes and fetal status were analyzed.The incidences of abortion (11.1％),premature delivery (8.3％),preeclampsia (11.1％),gestational diabetes mellitus (GDM,13.9％),anemia (16.7％),fetal distress (8.3％) and fetal growth retardation (FGR,5.6％) in clinical hypothyroidism group were higher than those in normal control group (2.9％,1.4％,1.4％,2.2％,4.3％,0.0％ and 3.6％).And the differences were statistically significant (P ＜ 0.05).The incidence of adverse pregnancy had a significant correlation with hypothyroidism in pregnant women.Therefore screening of thyroid functions is essential for improving pregnancy outcomes of pregnant women with hypothyroidism.

Under pathologic conditions, nitric oxide causes peripheral insulin resistance by impairing key signal molecules of insulin signaling pathway and mediates dysfunction of islet ? cells caused by lipids, cytokines and hyperglycemia, which plays an important role in the pathogenesis of type 2 diabetes mellitus.

Objective To investigate the risk factors of hemorrhagic transformation (HT) after cerebral infarction. Methods The clinical and neuroimaging data of 100 patients (gender,age-matched)with cerebral infarction and hemorrhagic transformation from January 2005 to January 2010 were analyzed retrospectively. The following factors were listed for single factor analysis: the history of hypertension, diabetes mellitus,admission blood pressure,blood sugar,infarction size,alcohol,smoking,atrial fibrillation,hypercholesterolemia, combined anticoagulant and antiplatelet aggregation therapy. All the above factors were analyzed by chi-square test or t test, and Logistic regression analysis was used to screen out the related risk factors of HT from the potentially related factors. Results Atrial fibrillation (OR =5.483,95%CI:fibrillation,extensive cerebral infarction,blood sugar,high blood pressure at the beginning of the disease,combined anticoagulant and antiplatelet aggregation therapy are the major risk factors of HT. At the same time, the occurrence of HT is the result of the joint effect of multiple factors and multiple mechanisms.

This study was aimed to discuss the distribution and protein expression level ofμ-opioid receptor (MOR) in hippocampus of premenstrual syndrome (PMS) liver-qi stagnation rat model, in order to initially reveal the action mechanism of PMS liver-qi stagnation and intervention effect ofShu-Yu (SY) capsule. Chronic restraint stress method was used to copy PMS liver-qi stagnation rat model.SY capsule ofTiao-Gan prescription was given as intervention. Immunofluorescence (IF) and western blot (WB) technique were used to detect MOR in hippocampal CA1 and CA3 brain area of rats from each group. The results showed that compared with the normal group, the hippocampus MOR distribution arrangement was messy with increased protein concentration in the model group (P< 0.01). After drug intervention, the MOR protein level returned to normal level. It was concluded that the pathogenesis of PMS liver-qi stagnation may be associated with high expression of MOR in hippocampus CA1 and CA3 region of rats. SY capsule can effectively correct and restore it to nearly normal level. It may be one of the central mechanisms in SY capsule treatment of PMS liver-qi stagnation.

Objectives To observe influences of two functionally important polymorphisms (5'-UTR and 3 -UTR) in thymidylate synthase (TS) gene and their combinative effects with drinking on the susceptibility of colorectal cancer (CRC). Methods A case-control study was designed, which included 140 CRC patients and 343 control subjects. Risk of CRC was estimated by unconditional Logistic model. Results The genotype distributions of the polymorphisms did not show significant differences between the cases and the controls. However, in those with -6 bp/-6 bp genotypes, the 2R carriers had a decreased risk (OR = 0. 60, 95%CI, 0. 23-1. 52) , but in +6 bp carriers, the 2R carriers had an elevated risk (OR=1. 87, 95%CI, 0. 94-3. 72). The likelihood test revealed the interaction existed between these two polymorphisms (P for interaction = 0. 05). Moreover, the combinative effect between the 3 -UTR polymorphism and alcohol drinking showed a significant association with the susceptibility of CRC (P for interaction =0. 01). In non-drinkers, the-6 bp allele carriers had a significant decreased risk (OR = 0. 57, 95%CI, 0. 32-0. 99) , but in ever and current drinkers, the +6 bp allele (6-bp insertion) carriers had an elevated risk (OR=1. 88, 95%CI, 0. 80-4. 41) , in which OR values ascended with the prolongation of drink-time. Conclusions The polymorphisms of thymidylate synthase at 5'-UTR and 3'-UTR may not be regarded as independent predictive factors for the susceptibility of CRC. However, interactions exist in these two polymorphisms and between the 3'-UTR polymorphism and drinking. Further studies with larger sample size and in different ethnic groups are needed.

Objective: To observe the effects of Lulutong injection on microcirculation disturbance after burns. Methods: Eighty-eight patients with mild burn were randomly divided into two groups. From the first day after burn, the treatment group received 500 mg Lulutong injection intravenously injected in 5% glucose, once a day for 14 days as a therapeutic course. The control group was treated with 5% glucose. No large amount of solution was infused because the burned patients were mild and no shock was found. Both groups were received anti-infection treatment using 0.6 g of clindamycin. The morphology of nail-fold microcirculation , the state around the nail-fold microcirculation, hemorrheological parameters, changes in coagulation function 3, 7 and 14 days after burn and the side effects of drugs were observed. Results: Compared to the control group, in the treatment group, the arterioles dilated more markedly, the blood flow of micro-vessels became faster, the flowing score of nail-fold microcirculation decreased obviously, the state around the nail-fold microcirculation changed significantly, the total score declined faster, but no obvious changes were found in erythrocyte aggregation index, the number of leukocyte adhesion and coagulation function . There were 2 cases with dizziness. Conclusion: Lulutong injection may improve the microcirculation in patients with burn, and has little side effect.

This study was aimed to elucidate the 5-HT3R molecular mechanism of Radix Paeoniae Albaextract (RPAE) as drug intervention in the treatment of premenstrual syndrome (PMS) model rats with liver-qi depression pattern.PMS model rats with liver-qi depression pattern were prepared.And then,the model was treated with RPAE.The protein distribution of 5-HT3AR and 5-HT3BR in the frontal lobe was evaluated by the immune fluorescence technology and western blot.The results showed that there were positive expressions of 5-HT3AR and 5-HT3BR in frontal lobe of rats in each group.Compared with the normal group,the 5-HT3AR and 5-HT3BR protein expression levels of the frontal lobe in the model group increased significantly (P < 0.05).Compared with the model group,the 5-HT3AR protein expression level in the frontal lobe decreased significantly after RPAE treatment (P < 0.05).In conclusion,RPAE regulated the protein expressions of 5-HT3AR and 5-HT3BR in frontal lobe,which may be one of the mechanisms for its treatment of PMS with liver-qi depression pattern.

Objective To investigate renal expression of ApoE in human lupus nephritis (LN) and its relationship with renal damages.Methods Renal expression of ApoE was examined in 40 LN patient biopsy samples by immunohistochemieal staining.The relationship between ApoE levels" and renal pathologic changes,renal injuries was analyzed.Results Only weak ApoE expression was found in normal renal tissue.The expression of ApoE was significantly higher in LN patients [ glomerular:(31.2±11.0) vs (3.0±1.6);tub-ular:(71.64±8.90) vs (0.60±0.06)].The expression of ApoE was higher in class IV than non-class IV LN [glomerular: (38.4±4.5) vs (18.0±4.6);tubular: (77.6±2.5) vs (60.0±3.2)].Spearman's relation-ship analysis showed that the expression of ApoE in glomerular and tubular was closely related to the renal histological score activity index and functional changes in LN (P＜0.01).Conclusion The expression of ApoE is high in renal tissues of LN,especially in class IV,and the high expression may be associated with LN activity and progressive renal dysfunction.

Objective:To investigate the mRNA expression of the WIF-1 gene and the methylation of its promoter in breast can-cer, and to determine the correlation between the epigenetic aberrant WIF-1 DNA methylation and the clinicopathological significance of WIF-1 in breast cancer . Methods:RT-PCR and sensitive methylation-specific-PCR (MSP) were used to detect WIF-1 mRNA ex-pression and the methylation of the WIF-1 promoter in 30 breast cancer samples as well as in tumor-adjacent tissue samples and 9 be-nign breast tissues. Results:The WIF-1 mRNA expression in 30 breast cancer samples significantly decreased compared with those of the other two groups. In addition, WIF-1 methylation was more frequent in breast-tumor tissues compared with those in tumor-free tis-sues. Meanwhile, WIF-1 mRNA expression in breast cancer tissues involved the abnormal methylation of its promoter. Clinicopatholog-ical correlation analysis showed that the abnormal methylation of the WIF-1 gene promoter was not associated with age, TNM stage, histotype, or lymph node metastasis. Conclusion:WIF-1 mRNA expression loss due to abnormal methylation may be a crucial factor in breast cancer development and can thus be used in the prognosis and progression of the disease.
