Therapeutic potential of intravenous Xuebijing on transforming growth factor β1 and procollagen type Ⅲ peptide in patients with acute paraquat poisoning

Objective

Paraquat (PQ) poisoning-induced pulmonary fibrosis causes asphyxiation and death. The therapeutic potential of intravenous Xuebijing therapy in PQ poisoning patients and its underlying immunomodulatory effects on transforming growth factor (TGF)-β₁, and procollagen type III peptide (PIIIP) were investigated.

Methods

Thirty-six acute PQ poisoning patients were randomly assigned to conventional therapy (Group A) and intravenous Xuebijing administration plus conventional therapy (Group B). Twenty volunteers served as controls (Group C). Blood samples were collected upon admission (day 0) and at post-treatment days 5, 10, and 14. TGF-β₁ and PIIIP concentrations were determined by ELISA and analyzed for intra- and inter-group differences over time. One-month follow-up was conducted for determining the mortality rate.

Results

TGF-β₁, and PIIIP levels were significantly higher in PQ poisoning patients and increased over time (Groups A and B vs C, P<0.01). However, the TGF-β₁ and PIIIP levels were consistently significantly lower in Group B compared with those of Group A (P<0.01). The 1-month mortality rate was also lower in Group B compared with that of Group A (P<0.05). PQ poisoning patients showed remarkably high levels of TGF-β₁ and PIIIP, which increased as PQ-induced pulmonary fibrosis progressed.

Conclusion

Treatment with intravenous Xuebijing plus conventional therapy significantly lowered TGF-β₁ and PIIIP levels, which indicates therapeutic efficacy in the treatment of PQ poisoning patients.     

The influence of impact object characteristics on impact force and force absorption by mouthguard material

Abstract –  Most impact force and impact energy absorption tests for mouthguards have used a steel ball in a drop-ball or the pendulum device. However, in reality most sports-related trauma is caused by objects other than the steel ball, e.g. various sized balls, hockey puck, or bat or stick. Also, the elasticity, the velocity and the mass of the object could change the degree and the extent of injuries. In this study, we attempted to measure the impact force from actual sports equipment in order to clarify the exact mechanism of dental-related sports injuries and the protective effects of mouthguards. The present study was conducted using the pendulum impact device and load cell. Impact objects were removable. Seven mobile impact objects were selected for testing: a steel ball, baseball, softball, field hockey ball, ice hockey puck, cricket ball, and wooden baseball bat. The mouthguard material used in this study was a 3-mm-thick Drufosoft (Dreve-Dentamid GmbH, Unna, Germany), and test samples were made of the one-layer type. The peak transmitted forces without mouthguard ranged from the smallest (ice hockey stick, 46.9 kgf) to the biggest (steel ball, 481.6 kgf). The peak transmitted forces were smaller when the mouthguard was attached than without it for all impact materials but the effect was significantly influenced by the object type. The steel ball showed the biggest (62.1%) absorption ability while the wooden bat showed the second biggest (38.3%). The other balls or the puck showed from 0.6 to 6.0% absorbency. These results show that it is important to test the effectiveness of mouthguards on specific types of sports equipment. In future, we may select different materials and mouthguard designs suitable for specific sports.

紫绀型先心病婴幼儿心肺转流期间Pv-aCO2/Ca-vO2对低氧的预测作用

Objective To explore the predictive value of venous-arterial-carbon dioxide partial pressure difference and arteriovenous oxygen content difference (Pv-aCO2 /Ca-vO2) to hypoxia during cardiopulmonary bypass (CPB) in infants with cyanotic congenital heart disease (CCHD). Methods Thirty children (0-1 year-old) with CCHD underwent cardiac surgery were enrolled. Arterial blood carbon dioxide partial pressure［pa(CO2)］, central venous blood carbon dioxide partial pressure［pv(CO2)］, arterial oxygen partial pressure［pa(O2)］, central venous oxygen partial pressure［pv(O2)］, arterial oxygen saturation (SaO2), central venous oxygen saturation (SvO2), arterial hemoglobin concentration (CaHb), central venous hemoglobin concentration (CvHb), arterial blood lactate (Lac), mean arterial pressure (MAP) and nasopharyngeal temperature were recorded, and arterial blood gas and venous blood gas were also checked at five different points of time: after tracheal intubation (T1), 5 min after ascending aortic clamping (T2), 5 minutes after the ascending aorta was opened (T3), off CPB (T4), end of ultrafiltration (T5). Pv-aCO2/Ca-vO2 was calculated according to formula. Changes of Pv-aCO2/Ca-vO2, Lac, MAP and nasopharyngeal temperature were comparison at each time points. Data of blood creatinine for seven consecutive days after surgery were recorded. The correlation between Pv-aCO2 / Ca-vO2 and Lac at each time point was analyzed. The receiver operating characteristic (ROC) curve was used to analyze the predicted value of Pv-aCO2/Ca-vO2 to hypoxia at different time points. According to the Kidney Disease: Improving Global Outcomes (KDIGO), infants with acute kidney injury (AKI) were diagnosed. The incidence of AKI was compared at each time point between infants with high Pv-aCO2 /Ca-vO2 and infants with high Lac. Results Pv-aCO2/Ca-vO2 and Lac were significantly increased in T1 compared with that of T2, T3 and T4 (P＜ 0.01). There was no significant difference in Pv-aCO2/Ca-vO2 between T5 and T1 (P＞0.05). Lac was significantly higher at T5 than that of T1 (P＜0.05). Pv-aCO2 /Ca-vO2 and Lac were significantly lower at T5 compared with those of T4 (P＜0.01 and 0.05). Compared with T1, MAP and nasopharyngeal temperature were significantly lower at T2 (P＜0.05). There was no statistical difference at other time points (P＞0.05). Values of Pv-aCO2/Ca-vO2 were positively correlated with Lac at T2 and T3 (r=0.87, P＜0.01; r=0.68, P＜0.01). The area under the curve (AUC) for predicting hypoxia of Pv-aCO2/Ca-vO2 at T2 was 0.926 (95% CI: 0.670-0.997, P＜0.0001), the cut-off value of Pv-aCO2 / Ca-vO2 was 0.35, the diagnostic sensitivity for hypoxia was 100% and the specificity was 77.78%. There was no statistical significance for predicted hypoxia with AUC of Pv-aCO2 / Ca-vO2 at T3 (P＞0.05). Compared with the incidence of postoperative AKI in infants with Lac＞3 mmol/L at T2, the incidence of postoperative AKI was significantly higher in infants with Pv-aCO2/Ca-vO2＞0.35 at T2 (P＜ 0.05). Conclusion During CPB in infants with CCHD, when Pv-aCO2 / Ca-vO2 is higher than 0.35 at 5 min after aortic clipping, it can identify hypoxia and predict postoperative AKI better than Lac.     

社会文化心理视角下的英汉医学术语比较

从文化渊源、文化借用和文化心理等3个方面探讨英汉医学术语承载的社会文化心理。西方医学衫暖舌希腊和古罗马文化影响,英语医学术语大部分源自希腊、罗马神话。英语医学术语对外来语的大量借用,反映出英语民族的“开放型”文化心理。汉语医学术语与中国古代文化渊源相通,其完整独特的医药文化限制了对外来医学词语的借用,是汉民族长期以莱自我中心意识和“封闭型”文化心理的具体体现。通过英汉医学术语对比说明语言作为重要的文化现象,必然妾勃嚏族毖杞心理的制约和影响。
