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 examine the validity and reliability of the abbreviated mental test (AMT) among Chinese subjects. Methods Two groups of subjects participated in the study. One group consisted of 38 patients with neurological disorders and the other 30 normal subjects (control group). They were assessed twice with AMT and mini mental state examination (MMSE) within one week. Results AMT was significantly correlated with MMSE as far as the total score and item scores were concerned( r =0.706～0.833).There were moderate to high correlation in all the items of AMT between the two assessment tools(ICC=0.810～0.996). The AMT scores in the patient group were significantly lower than that in the control group (7.60?2.55 vs 9.64?0.81, P

Objective To study the effect of pulse pressure(PP)/mean artery pressure(MAP) ratio in evaluating arteriosclerosis.Methods Blood pressures from 200 subjects without cerebrovascular nor cardiovascular disease were obtained and analyzed by different age groups.PP/MAP ratio was calculated for each patient and compared.Results PP/MAP ratio was significantly different in different age groups.Conclusion PP/MAP ratio has clinical significance in evaluating arteriosclerosis and is worthy of further investigation.

Objective To study the reliability, validity, sensitivity, specificity and predictive value of the Standardized Swallowing Assessment (SSA) in assessing swallowing function. Methods Sixty-seven stroke patients with dysphagia participated in the study. They were assessed twice with the SSA within 3 days. In addition, the patients' swallowing was also assessed using videofluoroscopy. Results There was high correlation in all items of the SSA between the two separate assessment sessions. The intraclass correlation coefficient was 0.85 for intrarater re- liability and 0.82 for interrater reliability. The SSA and videoflouroscopy results were highly correlated in terms of their total scores (r = -0.86,P≤0.01). Using the videoflouroscopy result as the standard, the sensitivity and spe- cificity of the SSA were 77.8% and 68.1% , respectively. At the same time, the positive and negative predictive val- ues were 48.3% and 88.9% , respectively. Conclusions The SSA has satisfactory reliability and validity, and higher sensitivity and specificity than videoflouroscopy. It is recommended for assessing swallowing with stroke pa- tients.

Objective To assess the cognitive function of subjects with brain injury with Loewenstein occupational therapy cognitive assessment (LOTCA) and mini-mental status examination (MMSE). Methods Two groups of subjects participated in this study. One group consisted of 36 subjects with brain injury (patient group). They were 28 males and 8 females,aged 61.0?16.7 years old. The other group was made of 44 healthy subjects (control group),with 25 males and 19 females,aged 55.4?23.7 years old. All subjects were assessed using LOTCA and MMSE and the results of them were analyzed. Results There was high correlation between the total scores of LOTCA and those of MMSE ( r =0.892,P

Objective To investigate the correlation between social factors and postpartum depression.Methods A total of 182 parturients were investigated with Edinburgh Postnatal Depression Scale (EPDS)and self-designed questionnaire.The social factors and postpartum depression of parturients were analyzed using univariate and multivariable logistic regression analysis.Results Family income,relation of family,relation of couples,sex of newborns and negative life events were associated with the risk of postpartum depression.Conclusions Low family income,bad relation of family,bad relation of couples,female newborns,and negative life events during pregnancy may increase the risk of postpartum depression.

Objective To study the effect of combination of Hydrochlorothiaside (HCTZ) with Captopril or spironolactone on serum high-sensitivity C-reactive protein (hsCRP) in hypertension patients. Methods A multi-centre, random and parallel control study was applied in this study. Slight and moderate hypertension patiens were se-lected. The patients were treated with placebo for two weeks and HCTZ 12.5 mga day for 6 weeks,wbo were then randomly divided into HCTZ group(12.5 mg once a day), spironolactone group(HCTZ 12.5 mg once a day + Spi-ronolactone 20 rag once a day) and captopril group(HCTZ 12.5 mg once a day + Captopril 25 rag twice a day) . By the end of one-year follow up, HCTZ group was randomly added to Spironolactone group and Captopril group because combination therapy was superior to single medication,which was recognized. During the treatment, the patients were followed up once a month ,for monitoring blood pressure, and serum hsCRP level was measured every year. Follow-up last for 4 years. By the end of 4 years, the patients were divided into treatment group and control group in order to compare the changes of serum hsCRP levels. Results At the end of 4 years, the blood pressure and serum hsCRP level were significantly decreased as compared with baseline, and were statistically different from that of control group (P <0.05 or 0.01). Multi-factor analysis showed that pre-treatment systolic blood pressue and serum hsCRP level, post-treatment decrease value of systolic blood pressue and age were the major influencing factors for the de-crease of serum hsCRP level(P < 0.05 for each). Conclusion The long-term combinaion of HCTZ with Spironolactone or Captopril not only effectivley decreases blood pressure but also decreases serum hsCRP level. The decrease value of systolic blood pressure is the major factor for influencing serum hsCRP level.

The intestinal microbiota refers to the microbial group that exists in the intestine, and its composition disorder may affect human health. Many studies have found that intestinal microbiota and their metabolites may be closely related to the pathologies of Alzheimer′s disease (AD) through the gut-brain axis. This article will review the roles and possible mechanisms of lipopolysaccharide, functional bacterial amyloid proteins and bile acids, which are common metabolites of intestinal microbiota, in the pathogenesis of AD, and provide valuable information for exploring the pathogenesis of AD.
