Objective: To explore the relationship between prenatal anxiety and cesarean section (c-section) with non-medical indication.
Methods: Nested case-control study was used to analyze the risk factors for c-section with no medical needs: 433 pregnant women with gestational age longer than 24 weeks were enroled in this study. According to the mode of delivery, we divided them into a vaginal delivery group, a c-section group without medical need and a c-section group with medical need.
Results: The c-section rate was 62.1%, 55.8% of which was c-section without medical need at family request. The score of state anxiety (S-AI) and trait anxiety (T-AI) was 42.53±11.04 and
44.40±10.23 respectively, much higher than that of normal population. After the adjustment of maternal social economic status and other prenatal statuses for this pregnancy, the prenatal anxiety was still associated with c-section with non-medical indication. The adjusted odd ratio for prenatal anxiety state, prenatal trait anxiety state and c-section with non-medical indication was 1.41 (95%CI: 1.06-1.87) and 1.23 (95% CI: 1.08-1.40), respectively.
Conclusion: Prenatal anxiety state is a risk factor for c-section with non-medical indication.

Objective To observe the law of removing dampness, melting phlegm and tonifying spleen on blood lipids in hyperlipidemia rat and its vascular endothelial protective effect. Methods Animals were randomly divided into 6 groups, the high-fat diet of 35 d, 16 d orbital check blood lipids to confirm modeling success and gavage was given by different experimental requirements. NOS and vascular endothelial gene expression were determined at 3rd and 7th day. Results After treatment, NOS expression in experimental rats compared with the normal group, P

A novel method for assaying the enzymatic activity of ribosome-inactivating proteins(RIPs) has been developed.The principle of the method is based on that RIP can remove some adenine bases from double-stranded supercoiled DNA molecules,subsequently,the deadenylated DNA was cleaved into nicked and linear form.After treatment with acidic aniline,the deadenylated DNA was degraded into many small fragments,and run out of the gel.The enzymatic activities of two RIPs(trichosanthin and cinnamomin) were tested using this method,the limit of sensitivity is about 50 ng(trichosanthin) and 5 ng(reduced cinnamomin) .It should be emphasized that the merit of this method is to avoid the preparation of ribosome.

Objective To study the effect of mental intervention on pregnant result in patients undergoing IVF-ET treatment.Methods 206 patients undergoing IVF-ET treatment in the hospital from February 2012 to Jan-uary 2013 were selected and randomly divided into two groups. The experiment group (n=103) was followed by mental intervention after the patients enrolled the IVF-ET treatment, the control group (n=103) enrolled the IVF-ET treatment without mental intervention.Results The HAMA and HAMD quantity grades for anxious and depression of patients in the experiment group were significantly lower than those of control ( <0.01), and the pregnancy rate of experiment group (45.63%) was higher than that of control (30.10%) <0.05. Conclusion Mental intervention for patients undergoing IVF-ET treatment could alleviate their anxiety-depression and improve the pregnancy rate of IVF.

AIM:To explore the effect of aldosterone on visfatin gene expression and secretion in 3T3-L1 preadipocytes or adipocytes.METHODS:Aldosterone at concentration of 10-8 or 10-6 mol/L with or without 10-6 mol/L spironolactone was added to cultured 3T3-L1 preadipocytes or adipocytes for 24 h or 48 h.The mRNA levels of visfatin and mineralocorticoid receptor were measured using real time PCR.The concentration of visfatin in the culture medium was determined by ELISA.RESULTS:In 3T3-L1 preadipocytes treated with aldosterone,the mRNA expression of visfatin reduced and the mRNA expression of mineralocorticoid receptor(MR) increased,but the concentration of visfatin in culture medium was not regulated significantly by aldosterone.In adipocytes with aldosterone treatment,the mRNA expression of visfatin and visfatin concentration in culture medium reduced,and mRNA expression of MR increased.The effect of aldosterone was blocked by spironolactone to some extent.CONCLUSION:Aldosterone inhibits the gene expression and protein secretion of visfatin in 3T3-L1 adipocytes.

Objective To study and distinguish the sonographic characteristics of chronic lymphocytic thyroiditis (CTL) and its nodules.Methods Ultrasonographic characteristics of 107 patients with histologically confirmed CTL was observed with a 7.5-12 MHz transducer and confirmed with the operation and pathology.Seventy four cases of CTL were examined by color Doppler flow image (CDFI),serum thyroid hormone levels were determined in 38 cases of CTL.Results In 57 cases of CTL,the pattern of diffuse low echoes was found in 14 cases (24.6 %),and nodulose pattern in 43 cases (75.4 %) in which diffuse numerous hypoecoie microdules in 16 (37.2%),and sporadic small nodules in 27 (62.8 %).All cases showed degeneration and disappearance of thyroid follicles,lymph cells invasion in varying degrees on pathology.Nodular goiter was commonly detected in 40 cases CTL (37.4 %),adenoma in 4 cases (3.7 %),hyperthyroidism in one case,non-Hodgkin lymphoma in one case,thyroid carcinoma in 4 cases (3.7 %).Color dopple flow imaging showed in 74 cases,0-Ⅰ 34 cases,Ⅱ 38 cases,Ⅲ 2 cases.The increased flow were observed in 38 cases in both Anti-Tpo and Anti-TG,and in 26 cases in TSH.Conclusion Ultrasonography is complex in CTL,with more complications.Ultrasonography are distinguished between the nodule of CTL and the nodule in the other thyroid diseases.Ultrasonography could help to avoid unnecessary surgical intervention,and provide strong evidence for CTL and its complication in clinic treatment.

Objective X-linked adrenoleukodystrophy (X-ALD) is a genetically determined disorder that is characterized by demyelination of central nervous system,and impaired adrenal cortex and abnormal accumulation of very long chain fatty acids in body fluid and tissue.The clinical manifestation,biochemical change,and magnetic resonance imaging were analyzed.Methods Clinical data of 11 cases with X-ALD were summarized and analyzed,including symptoms,signs,and inspection result.Relevant literature was reviewed.Results All cases were males,whose average onset age was (7.2 ± 4.7) year-old.It was (2.4 ± 1.9) years that the mean interval appears from onset to diagnosis.Six cases were with onset of adrenal insufficiency (AI),remaining 5 onset neural symptoms,where plasma very-long-chain fatty acids (VLCFA) was tested in 6 patients,all with abnormally high levels and brain magnetic resonance imaging(MRI) showed demyelination of cerebral white matter in 9 ones.Conclusions ALD is a X-linked genetically determined disorder that mainly affects the nervous system and adrenal gland.Plasma VLCFA test,ALD gene test,and cerebral MRI are reliable diagnostic methods.Early diagnosis and appropriate therapy would improve survival and neurological outcomes.

Interin-linked kinase (ILK)is a kind of effector of intra-and extracellular biological signal transduction,partici-pating in the formation of multiple signal pathways,it plays an important role for occurrence and development of heart dis-eases such as cardiac hypertrophy,coronary heart disease,viral myocarditis,dilated cardiomyopathy etc..

The ratio of plasma aldosterone concentration to plasma renin activity (ARR) is a practical parameter in screening for primary aldosteronism (PA).However,variations of the cutoff value of ARR in different studies have been reported due to plenty of influential factors that may affect the secretions of renin and aldosterone. Lack of standardization of assays for ARR also makes direct comparisons among different studies difficult.The associated influential factors on ARR were introduced in this review.
