Relationship between placental inflammation and fetal inflammatory response syndrome and brain injury in preterm infants / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To explore the relationship between histological chorioamnionitis (HCA) and fetal inflammatory response syndrome (FIRS) and brain injury in preterm infants.</p><p><b>METHODS</b>One hundred and three singleton infants with premature rupture of membranes (PROM) (gestation ages of less than 34 weeks) were enrolled. All the placentas were submitted for pathological evaluation. Umbilical cord blood interleukin 6 (IL-6), interleukin 8 (IL-8), tumor necrosis factor alpha (TNF-α) and granulocyte-colony stimulating factor (G-CSF) levels were measured with liquid chip. All preterm infants accepted brain imaging examinations. Based on the placental pathological examination and umbilical cord blood level of IL-6, the 103 infants were classified into HCA⁻ FIRS⁻, HCA⁺ FIRS⁻, and HCA⁺ FIRS⁺ groups.</p><p><b>RESULTS</b>The incidences of HCA, FIRS, and brain injury were 53.4%, 20.4% and 38.8% respectively. The prevalence of brain injury in HCA⁻ FIRS⁻, HCA⁺ FIRS⁻, and HCA⁺ FIRS⁺ cases was 21%, 41%, and 76% respectively (P<0.01). The grade 2 and grade 3 of placental inflammation and the inflammation at stage 2 and stage 3 increased the risk of brain injury. The cord blood levels of IL-8, TNF-α, and G-CSF in the HCA⁺ FIRS⁺ group were significantly higher than in the other two groups, and the levels of the above parameters in the HCA⁺ FIRS⁻ were higher than in the HCA⁻ FIRS⁻ group (P<0.05).</p><p><b>CONCLUSIONS</b>Placental inflammation and FIRS are associated with brain injury in preterm infants. Preterm infants exposed to severe placental inflammation have an increased risk of brain injury. Cord blood IL-8, TNF-α and G-CSF may be involved in the process of brain injury in preterm infants with placental inflammation and FIRS.</p>

Effect of modified huopo xialing decoction in treating pi-wei dampness-heat syndrome and its impact on the tongue epithelial cell apoptosis / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To study the effects of modified Huopo Xialing Decoction (HXD) in treating patients of Pi-Wei dampness-heat syndrome (PWDHS) and its impact on epithelial cell apoptosis of tongue.</p><p><b>METHODS</b>Fifty patients with PWDHD were randomized depending on their visiting sequence into two groups, the 30 patients in the treatment group treated with HXD and the 20 in the control group treated with Domperidone. The therapeutic course for both groups was 2 weeks. Besides, a normal control group consisting of 30 healthy volunteers was set up. The changes of tongue fur, grade of major syndromes in different groups were observed and scored before and after treatment to evaluate the therapeutic effectiveness, and the apoptotic index (AI) was estimated using TUNEL technique.</p><p><b>RESULTS</b>AI in the two patient groups before treatment was obviously lower than that in the normal group (P < 0.01 or P < 0.05); after treatment, AI in the treatment group increased significantly (P < 0.01), with no difference from that in the normal group (P > 0.05), while in the control group, it only showed a slight trend of increasing. Similar outcome of tongue fur grades was seen in the two groups, it was improved significantly (P < 0.01) in the treatment group but insignificantly in the control group (P > 0.05). After treatment, syndrome scores were both lower in the two groups (P < 0.01), but the decrement in the treatment group was more significant than that in the control group (P < 0.01). Comparison between groups showed that the total effective rate in the treatment group was significantly superior to that in the control group (90% vs 65%, P < 0.01).</p><p><b>CONCLUSION</b>HXD has good clinical efficacy in treating PWDHS, and has good effect in alleviating the greasy yellow tongue fur in patients with PWDHS by accelerating the tongue epithelial cell apoptosis.</p>
