关于铬雾抑制技术

<正>一、简介结晶器公司电镀生产线主要从事六价铬镀铬,功能是用于工装模具电镀,而六价铬具有很强的氧化性和毒性,它可以腐蚀皮肤,还可以通过呼吸系统进入人的身体,容易得职业病。特别是近年来国家越来越重视对环境的保护,而这条电镀生产线具有高污染性,如控制不当,将会被迫停产整顿,将会影响公司的正常生产经营。今年年初,市环保部门重新制定了水中铬含量的标准,由原来的0.2毫克每升的铬含量降低到0.05毫克每升,并且不定时抽取水样,或到电镀工房测空气中的铬含量,一旦测出铬含量超标,立即下发通知单通知公司停产整顿并会受到经济处罚。为了保证这条电镀生产线能正常运作,提出了这项即环保又实用的工艺改进方案。     

Video-assisted thoracoscopic surgery （VATS） for bilateral primary spontaneous pneumothorax

Objective： To review our experience of the treatment of bilateral primary spontaneous pneumothorax （PSP） by video-assisted thoracoscopic surgery （VATS）. Materials and methods： Retrospective chart review was followed by an on-clinic or telephone interview. Patients were cared for by one thoracic surgeon in four medical centers or community hospitals in Northern and Central Taiwan. Thirteen patients with bilateral PSP underwent bilateral VATS simultaneously or sequentially from July 1994 to December 2005. Results： Twelve males and one female, with age ranging from 15 to 36 years （mean 23.1 years）, were treated with VATS for bilateral PSP, under the indications of bilateral pneumothoracis simultaneously （n=4） or sequentially （n=9）. The interval between the first and second contra-lateral VATS procedure for non-simultaneous PSP patients ranged from 7 d to 6 years. Eleven of 13 patients （84.6%） had prominent pulmonary bullae/blebs, and underwent bullae resection with mechanical or chemical pleurodesis. The mean operative time was （45.6±18.3） min （range 25-96 min） and （120.6±28.7） min （range 84-166 min） respectively for the non-simultaneous （second VATS for the recurrence of contralateral side after first VATS） and simultaneous （bilateral VATS in one operation） procedures. There was no postoperative mortality. However, prolonged air leakage （〉7 d） occurred in one patient （7.7%） who recovered after conservative treatment. The mean duration of chest tube drainage was 3.1 d and the median follow up period was 3.4 years. Conclusions： VATS is a safe and effective procedure in the treatment of bilateral PSP. Bilateral VATS is only recommended for patients with simultaneously bilateral PSP, because the incidence of recurrence, even with visible bullae, was not so high in my group and in some previous literature. Bilateral VATS in a supine position should only be used in selective cases, because of possible pleural adhesion or hidden bullae on the posterior si     

Treatment of zinc deficiency without zinc fortification

Zinc （Zn） deficiency in animals became of interest until the 1950s. In this paper, progresses in researches on physiology of Zn deficiency in animals, phytate effect on bioavailability of Zn, and role of phytase in healing Zn deficiency of animals were reviewed. Several studies demonstrated that Zn is recycled via the pancreas; the problem of Zn deficiency was controlled by Zn homeostasis. The endogenous secretion of Zn is considered as an important factor influencing Zn deficiency, and the critical molar ratio is 10. Phytate （inositol hexaphosphate） constituted up to 90% of the organically bound phosphorus in seeds. Great improvement has been made in recent years on isolating and measuring phytate, and its structure is clear. Phytate is considered to reduce Zn bioavailability in animal. Phytase is the enzyme that hydrolyzes phytate and is present in yeast, rye bran, wheat bran, barley, triticale, and many bacteria and fungi. Zinc nutrition and bioavailability can be enhanced by addition of phytase to animal feeds. Therefore, using phytase as supplements, the most prevalent Zn deficiency in animals may be effectively corrected without the mining and smelting of several tons of zinc daily needed to correct this deficiency by fortification worldwide.

超低和极低出生体重儿早期呼吸系统并发症临床分析

目的探讨超低和极低体重新生儿早期呼吸系统并发症的发生情况．认识NICU呼吸管理的重要性。方法对102例超低和极低出生体重儿临床资料进行回顾分析，结果呼吸暂停发生率为69．61％．其中15．49％表现为梗阻性呼吸暂停。新生儿呼吸窘迫综合征（NRDS）发生率48．04％，肺炎占30．39％．痊愈率81．37％。体重越低．RDS、呼吸暂停、肺炎的发生率越高（P〈0．01）。结论对超低和极低出生体重儿密切监护，加强呼吸管理．是救治早产儿的重要环节，可提高成活率和生存质量。
