Perinatal antibiotics exposure causes increase in serum 5-hydroxytryptamine level as well as changes in behavior and gastrointestinal motility in the male offspring in mice / 生理学报

The current study was aimed to investigate the potential effects of perinatal exposure to therapeutic dose of penicillin and cefixime on the cognitive behaviors, gastrointestinal (GI) motility and serum 5-hydroxytryptamine (5-HT) level in the offspring. Pregnant rats were continuously treated with cefixime or penicillin in the period between 1 week before and 1 week after labor. Behavior tests, including social preference, self-grooming and elevated plus maze tests, and intestinal motility tests were carried out on the offspring at age of 4 to 10 weeks. Serum 5-HT levels were detected with ELISA, and potassium/sodium hyperpolarization activated cyclic nucleotide-gated channel 2 (HCN2) and tryptophan hydroxylase 1 (TPH1) expression levels in colon epithelium of offspring were detected by Western blot and RT-qPCR. The results showed that, compared with the naive group, cefixime increased social behavior in the female offspring, but did not affect the male offspring. Compared with the naive group, cefixime significantly decreased colonic and intestinal transits, and increased cecum net weight and standardized cecum net weight in the male offspring, but did not affect the female offspring. The serum 5-HT levels in the male offspring, rather than the female offspring, in cefixime and penicillin groups were significantly increased compared with that in the naive group. The protein expression level of HCN2 in colon epithelium of the offspring in cefixime group was significantly down-regulated, and the TPH1 expression level was not significantly changed, compared with that in the naive group. These results suggest that perinatal antibiotics exposure may affect neural development and GI functions of the offspring, and the mechanism may involve peripheral 5-HT and gender-dependent factor.

Clinical effect of 1-desamino-8-D-Arginine Vasopressin different withdrawal ways in primary monosymptomatic nocturnal enuresis / 中国综合临床

Objective To explore the effect and compare the relapse rates of 1-desamino-8-D-Arginine Vasopressin(DDAVP) different withdrawal ways after initial 3 months in primary monosymptomatic nocturnal enuresis(PMNE) patients,in order to provide some evidences and references to use DDAVP to cure PMNE preferably.Methods Two hundred and fifty-six cases PMNE patients who were treated in Hubei Maternal and Child Health Hospital from November 2014 to June 2016 were selected and randomly divided into group A (DDAVP immediate withdrawal group,65 cases),group B(DDAVP day reduction group,58 cases) and group C (DDAVP step reduction group,60 cases).All patients were given DDAVP tables for 3 months.After 3 months for DDAVP,patients who were effective (full respond and partial respond) to DDAVP continued to undergo a withdrawal stage,those in group A underwent immediate cessation,those in group B continued to receive the effective dose every other day for 2 months and those in group C were step by step tapered by 0.05-0.10 mg every 2-4 weeks until completely stopped,the period was not more than 3 months.All patients had a follow-up visit for 3 months after cessation of DDAVP.Results A total of 183 patients completed the study finally,there were 65 patients in group A,58 patients in group B and 60 patients in group C.Initial 3 months the effective rates of group A,B and C were respectively 89.23％ (58/65),89.66％ (52/58) and 86.67％ (52/60),there were not statistically significant difference(x2 =0.309,P =0.857).There were 58 patients in group A,52 patients in group B and 52 patients in group C continued to undergo the withdrawal stage.One month after cessation of DDAVP,the effective rates of group B (88.46％,46/52) and group C (92.31％,48/52) were significantly higher than group A(67.24％,39/58) (x2 =7.030,P=0.008;x2 =10.417,P=0.001),while the relapse rates of group B(19.23％,10/52) and group C(17.31％,9/52) were significantly less than group A(36.21％,21/58) (x2=3.904,P=0.048;x2=4.937,P =0.026).Three months after cessation of DDAVP,the effective rates of group C (78.85％,41/52) were significantly higher than group A (50.00％,29/58) and group B (57.69％,30/52) (x2 =9.859,P=0.002;x2 =5.371,P=0.020),and the relapse rates of group C(32.69％,17/52) were significantly less than group A (55.17％,32/58) and group B (51.92％,27/52) (x2 =5.609,P =0.018;x2 =3.939,P =0.047),while the effective rates and relapse rates were not statistically significant difference between group A and group B(x2 =0.652,P =0.419;x2 =0.116,P =0.733).Severe adverse events related to DDAVP were not observed in any patients.Conclusion Gradual withdrawal after initial 3 months of DDAVP may improve the effect and reduce the relapse rates,the short-term and long-term curative effects of step-by-step withdrawal treatment are both well,while long-term curative effects of every other day withdrawal treatment is not obviously well.

Nutritional Knowledge, Attitude, and Practices among Pregnant and Lactating Women Living with HIV in the Manzini Region of Swaziland.

The prevalence of HIV infection in Swaziland (26%) is among the highest in the world. We investigated nutritional knowledge, attitude, and practices (KAP) and the influence of sociodemographic factors on KAP among pregnant and lactating women living with HIV in the Manzini region of Swaziland. Interviews were conducted using a structured questionnaire to collect data from 324 subjects seeking healthcare from selected regional hospitals, health centres, and clinics in Manzini region. The results showed mean percentage scores of nutritional knowledge (67%), attitude (67%), and practices (51%) whereby educational level (p=0.002), employment status (p=0.009), income (p=0.008), religion (p=0.007), type of accommodation (p=0.006), type of transport used when going for shopping (p=0.001), and BMI (p=0.015) were significantly associated with nutritional practices. Significant positive correlations between nutritional KAP were observed: nutritional K and A (r=0.155, p=0.005), nutritional K and P (r=0.456, p=0.001), and nutritional A and P (r=0.230, p=0.001). Multiple linear regression analysis indicated that type of transport used when going for shopping (p=0.002), educational level (p=0.001), income (p=0.001), employment (p=0.038), knowledge of food proportion in a plate (p=0.000), a positive attitude towards high-fibre diet (p=0.004), and eating a variety of foods (p=0.006) were predictors of nutritional practices. Educational level was identified as a common predictor of nutritional knowledge, attitude, and practices, suggesting that both formal and informal education systems are potential factors influencing dietary practices among pregnant and lactating women living with HIV in Swaziland.

Detection of tumor cells in peripheral blood of patients with gastric cancer using mRNA of MAGE genes as markers / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To develop a sensitive and specific RT-PCR assay using the mRNA of MAGE-1 and MAGE-3 genes as specific tumor markers for the detection of the tumor cells in the peripheral blood of patients with gastric cancer.</p><p><b>METHODS</b>Peripheral blood was obtained from 40 patients with gastric cancer and from 20 healthy volunteers. The mRNA of MAGE-1 and MAGE-3 genes in the peripheral blood mononuclear cells (PBMC) was detected by RT-PCR. The expressions of MAGE-1 and MAGE-3 mRNA in the tumor tissues of these gastric cancer patients were also detected by RT-PCR. Meanwhile,CEA expression by nested RT-PCR in PBMC of 40 gastric cancer patients was also detected.</p><p><b>RESULTS</b>Of 40 gastric cancer patients, MAGE-1 and MAGE-3 mRNA were positive in 47.5% (19/40) and 25% (10/40) of PBMC respectively, and in 62.5% (25/40) and 30% (12/40) of gastric cancer tissues respectively. As a whole, in the PBMC of 40 gastric cancer patients, 25 (62.5%) samples were found to express at least one type of MAGE mRNA. In the patients whose tumors did not express MAGE-1 and/or MAGE-3 genes, the corresponding MAGE mRNA was also undetected in their PBMC. There was no expression of MAGE-1 or MAGE-3 gene in the PBMC from the 20 healthy donors. The positive rate of MAGE mRNA in PBMC was closely correlated with the tumor stage and lymph node metastasis (P <0.05). Positive rate of CEA gene expression was 32.5% (13/40) in the PBMC of 40 gastric cancer patients, 29 (72.5%)samples were detected to express at least one type of MAGE gene and CEA gene mRNA.</p><p><b>CONCLUSIONS</b>MAGE-1, MAGE-3 and CEA mRNA are specifically detected with high percentage in the PBMC of gastric cancer patients by RT-PCR. They could be used as specific tumor markers for the detection of the circulating gastric cancer cells, and the detection results may be helpful to evaluate the prognosis of gastric cancer patients.</p>
