Relationship among maternal blood lead,ALAD gene polymorphism and neonatal neurobehavioral development

Lead is a widely used heavy metal that can affect children’s nervous system development. ALAD gene polymorphism is associated with lead neurotoxicity. This study aimed to clarify the relationship among maternal blood lead, ALAD gene polymorphism, and neonatal neurobehavioral development through detecting maternal blood lead and ALAD gene polymorphism. 198 maternal and neonatal were selected as the research object. Graphite furnace atomic absorption method was applied to detect the maternal blood lead concentration. PCR-RFLP was used to detect ALAD genotype distribution. Neonatal NANB score was treated as effect indicator. SPSS was used for statistical analysis. The ALAD genotype was 181 cases (91.4%) for ALAD₁₁ and 17 cases (8.6%) for ALAD₁₂. ALAD allele frequency distribution accords with genetics Hardy-Weinberg balance (P > 0.05). Blood lead level in maternal with ALAD₁₂ genotype was significantly higher than with ALAD₁₁ genotype (P < 0.01). NANB score in high blood lead neonatal group was obviously lower than the low blood lead group (P < 0.05). Newborn’s NANB score from the maternal with ALAD₁₁ genotype was lower than from the maternal with ALAD₁₂ genotype (P < 0.01). After ruling out the confounding factors influence by multiple linear regressions, ALAD gene polymorphisms had no significant correlation with neonatal NANB score (P > 0.05). ALAD gene polymorphism is associated with the blood lead level. Low level lead exposure in utero may cause newborn early neurobehavioral maldevelopment. Maternal ALAD gene polymorphism can affect early neonatal neurobehavioral development by influencing the blood lead level.

Association between outdoor ozone and compensated acute respiratory diseases among workers in Quebec (Canada)

Respiratory effects of ozone in the workplace have not been extensively studied. Our aim was to explore the relationship between daily average ozone levels and compensated acute respiratory problems among workers in Quebec between 2003 and 2010 using a time-stratified case-crossover design. Health data came from the Workers’ Compensation Board. Daily concentrations of ozone were estimated using a spatiotemporal model. Conditional logistic regressions, with and without adjustment for temperature, were used to estimate odds ratios (ORs, per 1 ppb increase of ozone), and lag effects were assessed. Relationships with respiratory compensations in all industrial sectors were essentially null. Positive non-statistically significant associations were observed for outdoor sectors, and decreased after controlling for temperature (ORs of 0.98; 1.01 and 1.05 at Lags 0, 1 and 2 respectively). Considering the predicted increase of air pollutant concentrations in the context of climate change, closer investigation should be carried out on outdoor workers.     

The effects of different GSK-3β inhibitors and dose-response relationship in severe acute pancreatitis associated kidney injury in rats北大核心CSCD

Objective: To observe the dose-response relationship of the GSK-3β inhibitor TDZD-8 in severe acute pancreatitis (SAP) associated kidney injury in rats. In order to identify the most effective class of GSK-3β inhibitor and its effective and reasonable safe dose in SAP associated kidney injury model in rats by comparing three kinds of frequently-used GSK-3β inhibitor TDZD-8, lithium chloride (LiCL), SB216763 in this model. Methods: Totally 96 SPF male Wistar rats were randomly(random number) divided into 8 groups (n=12): sham operation group (SO group), severe acute pancreatitis group (SAP group), TDZD-8 pretreatment groups (TD group, marked TD1, TD2, TD3 and TD4 group, respectively) at different dosage (0.25, 0.5, 1.0 and 2.0 mg/kg), LiCL pretreatment groups (L group, 40 mg/kg), and SB216763 pretreatment group (SB group, 1 mg/kg). SAP model was induced by retrograde infusion of 5% sodium taurocholate into the biliopancreatic duct. Rats in each group were sacrificed at 12 h after operation. Then the mortality, quantity of ascites, serum AMY, Cr, BUN and ALT were recorded, and the pathological changes of pancreatic tissues and kidney tissues were observed. Results: Compared with the SO group, the levels of ascites, serum AMY, Cr, BUN, ALT and pancreatic and renal pathologic score in the SAP group were all significantly increased (P<0.05). Compared with the TD, group, quantity of ascites, serum AMY, Cr, BUN, ALT and pancreatic tissue pathological grading were reduced in different degrees in the TD2, TD3 and TD4 groups with statistically significant difference (P<0.05); ALT values were reduce in different degrees in the TD2 and TD3 groups as compared with the SAP group (P<0.05), while ALT value in the TD4 group was similar to that in the SAP group; compared with the TD2 group, all the indexes in the TD3 group were significant better (P<0.05); Compared with TD3 group (the best group in TD group), the levels of ascites and serum ALT in the L group and SB group had no significant difference (P>0.05), but the levels of AMY, Cr, BUN, ALT, pancreatic and renal pathologic score were significantly reduced in the TD3 group than those in the L and SB groups (P<0.05); compared with the SB group, the values of Cr, BUN, pancreatic and renal pathologic score in the L group were lower (P<0.05). GSK-3β protein expression in all groups showed no obvious difference (P>0.05), while p-GSK-3β ser9 protein expression in the SAP group was lower than that in the SO group (P<0.05), and p-GSK-3β ser9 protein expression in the TD3, L and SB groups were stronger than that in the SAP group. Among them, p-GSK-3β ser9 protein expression was highest in the TD3 group, followed by the L group, finally the SB group, and the differences were statistically significant (P<0.05). Conclusions: Among the three different GSK-3β inhibitors, TDZD-8 is the most effective GSK-3β inhibitor for SAP associated with kidney injury in rats. The GSK-3β inhibitor TDZD-8 1 mg/kg administered intravenously is safe, effective and optimal dosage for attenuating the severity of severe acute pancreatitis associated with kidney injury. © 2018 Chinese Medical Association.
