The synergistic effect of phosphorus oxynitride（PON） with a novolac-based char former modified by salification （NA-metal salt） on the flame retardance of polyamide 6（PA6） was *** this purpose,various flame-retardant PA6 systems were melt-compounded with PON,PON/NA,PON/NA-V_2O_5 and PON/NA-Fe_2O_3,and their flame retardance was evaluated by measuring the limiting oxygen index（LOI） values and UL-94 vertical burning *** results showed that,compared with the PA6/PON/NA system,the combination of two char formers（NA-V_2O_5,NA-Fe_2O_3） with PON could obviously improve the char formation and flame retardance of *** flame retardance and cone calorimetric analyses showed the stronger synergism as well as the better flame retardant performance of PON/NA-Fe_2O_3 flame retardant system. The effects of different char formers on the flame retardance and thermal stability of this system were also discussed.

BACKGROUND: Hydrophobic bile acids lead to the generation of oxygen free radicals in mitochondria. Accordingly, this study is to investigate if gene delivery of superoxide dismutase (SOD) will reduce hepatocyte injury caused by experimental cholestasis. METHODS: The recombinant of pLNCX-SOD gene packaged with lipofection of AMINE was transfected into hepatocytes in vitro, which stably expressed the SOD gene. RESULTS: After transfection, hepatocytes enhanced the protective effect against injury to bile and the toxicity of serum in obstructive jaundice. The inhibition of bile at the concentration of 2% (v: v, bile: DMEM 1: 50) decreased obviously from (78.80 +/- 12.35)% to (43.35 +/- 9.69)% in 12 hours, from (82.55 +/- 11.27)% to (-26.64 +/- 7.66)% in 24 hours, and from (83.83 +/- 18.69)% to (-19.27 +/- 14.38)% in 48 hours, compared with that of the untransfected cells (P < 0.01). The inhibition of serum at the obstructive jaudice concentration of 2.5% was obviously decreased from (89.72 +/- 1.52)% to (14.68 +/- 14.33)% in 12 hours, from (92.2 +/- 11.27)% to (41.39 +/- 7.66)% in 24 hours, and from (94.25 +/- 8.96)% to (22.71 +/- 4.38)% in 48 hours (P < 0.01). CONCLUSION: Hepatocytes transfected with the pLNCX-SOD gene could obviously be resistant to the toxicity of bile and serum from rat with obstructive jaundice.

全球气候变化下的黄河上游径流量变化及其预测是流域生态水文研究的热点之一。利用2008—2020年流域内48个气象站的监测数据和头道拐水文站径流数据,系统分析了黄河上游流域径流量与气候要素变化的关系,并建立径流量预测模型。结果表明,单一月份的月平均气温、月降水量和月蒸散发量多未表现出显著的年际变化趋势,但年平均气温和年降水量显著上升,而年蒸散发量也有上升趋势但统计不显著;多数单一月份的月径流量和年径流量均在年际上呈显著增加趋势。在月平均气温、月降水量、月蒸散发量均与月径流量显著相关的基础上,基于气候要素建立的黄河上游流域径流量预测模型具有良好的预测效果。

Acute necrotising pancreatitis is characterized by inflammatory and necrotic events, which followthe initial intra-acinar injury involving enzyme activation, and disruption of the acinar cytoskeleton. At present, apoptosis has become a hot topic in many kinds of disease. Bax and Bcl-2 are the important control gene during cell apoptosis. 2 Previous study has shown that interleukin 10 （IL-10） is a kind of important antiinflammatory cytokine and plays a role of selfdefense mechanism,

BACKGROUND: Diaphragmatic hernia of the liver is a rare clinical entity, usually found after trauma in adults. This study was undertaken to elucidate a misdiagnosis of non-traumatic diaphragmatic hernia of the liver in an adult. METHOD: The clinical data of one patient with non-traumatic diaphragmatic hernia of the liver was analyzed. RESULTS: A tumor in the right lower thorax was revealed by chest X-ray and computed tomography. Non-traumatic diaphragmatic hernia of the liver was not identified until the operation. Pathological analysis confirmed the finding. The patient recovered well. CONCLUSIONS: Non-traumatic diaphragmatic hernia of the liver in an adult is a rare right-sided diaphragmatic hernia, which can move up into the chest cavity. It should be distinguished from lung cancer. The diagnosis and evaluation of non-traumatic diaphragmatic hernia of the liver can help optimize surgical management.
