Negative pressure wound therapy is a technique where negative pressure is applied to a wound to remove the accumulated fluid and infectious materials. Acute and chronic wounds are commonly treated using this therapy. The negative pressure wound therapy system consists of a vacuum pump, a foam or gauze wound dressing, drainage tubing, and an adhesive film dressing to cover and seal the wounds.

Business process outsourcing (BPO) is a segment of outsourcing that consists of subcontracting the business processes of an organization to a third-party vendor that has expertise in the required domains. These vendors then administer and manage the selected activity based on defined and measurable performance criteria. It helps clients increase their operational efficiency, concentrate on core competencies, reduce time-to-market, obtain access to fresh talent with experience in the latest technologies, and, in the long run, build an organization with an economical cost structure. Several healthcare providers have adopted BPO services because of proven benefits of cost reduction, improved patient care services, and maximized staff efficiency.

Medical products include pharmaceutical products, medical devices, surgical devices, and other healthcare-related products. The packaging of medical products is a complex process because of their molecular and chemical structures; they need to be packed in extremely protective and durable materials to prevent contamination. To achieve this, packaging materials are sterilized to remove any foreign body. Vendors in the Sterile Medical Packaging market in the US are continuously bringing out new packaging materials that offer enhanced protection to medical products. Some of the types of packaging used in this market are bottles, vials, blisters, tubes, prefilled syringes, and prefilled inhalers.

The Asia-Pacific biotech sector continued to expand over the last six months, due to the growing presence of foreign investors and a rapid increase in the number of biotech companies.

目的探索三聚磷酸铝替代硫酸催化合成阿司匹林的可行性。方法采用Benson基团贡献法、Joback基团贡献法,估算水杨酸与乙酸酐的反应体系的热力学函数,分析了该反应的焓变、熵变和吉布斯自由能随温度的变化,以及反应物酐酸摩尔比对平衡转化率的影响。结果在298.15 K~358.15 K的温度区间,该反应的焓变小于零,为放热反应,升温不利反应进行;在计算温度范围内提高反应的酐酸比,有利于增大平衡的转化率,当酐酸比为3时,理论转化率可达99.58%。结论从热力学角度考虑该催化合成反应是可行的。

目的探讨中药莲子心中4种生物碱莲心季铵碱(Lot)、莲心碱(Lien)、异莲心碱(Iso)和甲基莲心碱(Nef)对H2O2诱导人脐静脉内皮细胞株ECV304氧化损伤的保护作用。方法采用MTT法测定不同浓度Lot、Lien、Iso和Nef对正常和H2O2损伤ECV304细胞活性的影响,通过比色法测定并比较各组细胞一氧化氮(NO)及一氧化氮合酶(NOS)的水平。结果 Lot、Lien、Iso和Nef对正常ECV304细胞形态和活性均无影响;Lot为100μmol/L,Lien、Iso和Nef为0.1μmol/L时,对H2O2致损内皮细胞活性有较好的缓解作用,此时细胞活性分别为H2O2损伤组的112.8%、129.3%、125.6和118.2%(P<0.01或0.05)。4种生物碱在上述剂量时对H2O2致损内皮细胞形态的改善作用与阳性药卡托普利基本相近,除Lot的作用较弱外,Lien、Iso和Nef均可使受损内皮细胞的细胞间隙缩小,细胞彼此相连增强,细胞边界变清晰。另外,且4种莲子心生物碱均可提高H2O2致伤内皮细胞的NO浓度(P<0.05),增加损伤内皮细胞的NOS活性(P<0.05)。结论莲心季铵碱、莲心碱、异莲心碱和甲基莲心碱均对H2O2诱导内皮细胞损伤的有一定的保护作用,其作用机制可能是通过增加NOS生成提高血管内皮细胞释放NO,从而发挥保护内皮的功能。
