OBJECTIVETo study whether anxiety and depression are associated with the development of neurogenic urination in children.

METHODSA total of 136 9 to 12-year-old children with neurogenic urination (case group) and 136 age-matched healthy children (control group) were enrolled. The Screen for Children Anxiety Related Emotion Disorders (SCARED) and Depression Self-rating Scale for Children (DSRSC) were used to evaluate the psychological status. The incidences of anxiety and depression as well as the SCARED and DSRSC scores were compared between two groups. Logistic regression analysis model was used to evaluate the relationship between psychological status and the development of neurogenic urination.

RESULTSThe case group was found to have a higher incidence of anxiety and depression compared with the control group (P<0.01). The SCARED score in the case group (28.1 ± 8.6) increased significantly compared with 14.4 ± 4.9 in the control group (P<0.01). The DSRSC score in the case group was also significantly higher than in the control group (13.5 ± 4.8 vs 9.1 ± 3.2; P<0.01). The logistic regression analysis showed that the children with anxiety (SCARED-score>23) had a 1.224-fold increased risk for the development of neurogenic urination compared with the children with the SCARED-score≤23 and that the children with depression (DSRSC-score&ge;15) had a 1.148-fold increased risk for the development of this disorder.

CONCLUSIONSAnxiety and depression participate in the development of neurogenic urination in school children.

The instability of secondary metabolite production is a ubiquitous problem in plant cell culture. To understand the instability, the investigation of anthocyanin accumulation in suspension cultures of Vitis vinifera, as a model system, has been initiated in our laboratory. Suspension culture of a relatively homogeneous cell line E of V. vinifera, was established by long-term cell line selection by anthocyanin content differentiation. The aggregate size of E was smaller than that of other cell lines obtained by routine screening method. The variation coefficients of anthocyanin content in suspension cultures of E were 8.7% in long-term subcultures and 5% in repeated flasks, respectively. The effects of elicitor, precursor feeding and light irridiation on biomass and anthocyanin accumulation in suspension cultures of E had been investigated and the results showed that all the variation coefficients were lower than 12% and this indicated the importance of homogeneity on stable production in plant cell culture. With the combination treatment of 30micromol/L phenylalanine and 218micromol/L methyl jasmonate in the dark in suspension cultures of E, the anthocyanin content and production in suspension culture of E was 5.89-fold and 4.30-fold of the controls, respectively, and all the variation coefficients of biomass and anthocyanin accumulation were lower than those of the controls in 5 successive subcultures.

OBJECTIVETo investigate calcium, iron and magnesium intakes of preterm infants' mothers before and during pregnancy and calcium, iron and magnesium levels of preterm infants and their mothers in order to provide basis for studying the effect of nutritional factors on the occurrence of prematurity.

METHODSTwo hundred and forty matched cases (preterm infants and their mothers) and controls (term infants and their mothers) were recruited. A nutritional survey of calcium, iron and magnesium intakes was performed in the mothers before and during pregnancy. Calcium, iron and magnesium levels in maternal plasma and in cord blood, placenta, breast milk, meconium, and amniotic fluid were measured with axial view inductively coupled plasma optical emission spectrometry (ICP-OES).

RESULTSIron and magnesium intakes in preterm infants' mothers were significantly less than those in term infants' mothers before pregnancy (P<0.05). Iron and calcium intakes in preterm infants' mothers were also significantly less than those in term infants' mothers during pregnancy (P<0.05). Multivariate analysis of variance showed that iron and calcium levels of preterm infants' mothers were significantly lower than those of term infants' mothers (P<0.05). The preterm infants showed significantly lower iron and magnesium levels than term infants (P<0.05). Plasma levels of calcium, iron and magnesium in infants were positively correlated to maternal plasma levels of calcium, iron and magnesium (r=0.517, 0.622, 0.518, respectively; P<0.05).

CONCLUSIONSThe iron and calcium levels of preterm infants' mothers were lower than those of term infants' mothers, and the iron and magnesium levels of preterm infants were lower than those of term infants. The exact relationship between calcium, iron and magnesium levels and intakes before and during pregnancy needs to be explored further.

The low-production is a ubiquitous problem and has prevented the commercialization of secondary metabolite production in plant cell culture. In order to examine the effective approaches to improvement of secondary metabolite production in plant cell culture, the investigation of anthocyanins accumulation in suspension cultures of Vitis vinifera, as a model system, had been initiated in our laboratory. In this present research, various elicitors and the precursor of phenylalanine were used in combination to enhance the anthocyanins production in suspension cultures of Vitis vinifera. And an integrated process with the combination of elicitation, precursor feeding and light irradiation was reported for rational bioprocess design. Among the combination treatment of phenylalanine feeding and several elicitors (methyl-beta-cyclodextrin, dextran T-40, methyl jasmonate, extracts of Aspergillus niger and Fusarium orthoceras), the combination with methyl jasmonate gave the highest anthocyanins production in suspension cultures of Vitis vinifera. When compared to the controls, the anthocyanins content (CV/g, FCW) and production (CV/L) increased by 2.7-fold and 3.4-fold, respectively. The optimum time for the addition of phenylalanine and methyl jasmonate was 4 days after inoculation. Two cell lines with different anthocyanins-producing capacity responded differently to the optimum combination treatment of 30 micromol/L phenylalanine feeding, 218 micromol/L methyl jasmonate elicitation and 3000 to approximately 4000 1x light illumination. The high-and low-anthocyanins-producing cell lines of VV05 and VV06 produced the maximum of 2975 and 4090 CV/L of anthocyanins that were 2.5- and 5.2-fold of the controls, respectively.

Objective To determine the urinary iodine level of people in Yunyang and Bishan County of Chongqing and explore into its influencing factors. Methods Using multistage cluster stratified simple random sample method, Yunyang and Bishan County were chosen as research spots, then thirty children aged 8-10 in each 3 primary school of the 2 counties were selected using stratified randomization sampling method to inspected their urine and household salt for iodine and the iodine content in drinking water. Results Five hundred and seventy-one urine samples were inspected and the urinary iodine median was 261.47 μg/L. 5.78% (33/571) and 37.48%(214/571) of samples had an urinary iodine median less than 100 μg/L and more than 300 μg/L. The urinary iodine median of Yunyang County was higher than that of Bishan (H = 7.42, P < 0.01). The iodine salt coverage rate, the qualified rate and edible qualified iodine salt rate respectively were 99.64%(554/556), 94.22% (522/554) and 93.88% (522/556) in 556 samples of family table salt. Eighty-seven samples of drinking water were inspected, resulting an averaged iodine content of 8.81 and 2.97 μg/L, respectively in the 2 counties. Conclusions The 2 counties are all the area of iodine deficiency. The urinary iodine level, although meeting the demand of eliminating iodine deficiency diseases, is a little bit higher given that iodized salt of present doage has been taken for a long time. The content of iodized salt should be adjusted accordingly.

Objective To investigate the characteristics of carotid atherosclerosis (CA) in patients with acute ischemic cerebrovascular disease (AICD) and explore the relation between metabolic syndrome (MS) and CA. Methods Color Dopple ultrasound was used to examine the carotid artery of 514 patients with AICD and 300 healthy subjects as control group. The intima-media thickness (IMT) of common carotid artery, carotid plaque index, the occurrence rate of CA and the prevalence of MS were compared between the 2 groups. Patients with AICD were divided into CA group and non-CA group according to the occurrence situation of CA; the prevalence of MS and the correlation between MS and single risk factor were analyzed. Results The prevalence of MS, IMT, carotid plaque index and the occurrence rate of CA in the AICD group were all significantly higher than those in the control group (P<0.05). The prevalence of MS, and the incidence of hypertension and high levels of triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), and total cholesterol (TC) in the CA group were significantly increased than those in the non-CA group. After age, gender and smoking adjusted and further adjusted component risk factors of MS, the MS defined by CDS criteria was associated with a 1.81 to 3.96 fold high risk of the CA. The risk of CA in patients with MS accompanied with diabetes was 5.6 times higher than that in patients with MS alone. Conclusion The prevalence of MS and CA in patients with AICD was high. The MS was positively associated with the risk of CA and cooperated with its component risk factors or diabetes to further impact CA.
