A new spectrophotometric method, ion-exchanger colorimetry for measuring iron (Ⅱ) in powdered milk fortified with iron(Ⅱ) has been developed. The method was based on the direct measurement of the resin phase absorbance after the absorption of colored sample complex species. In this method, 1,10-phenanthroline was used as the colour reagent, citric acid-sodium citrate as buffer and citric acid-ammonia as masking agent.The recovery rate of the method was 102%. Coefficient of variation was 5.84%.This method was a sensitive, reliable and simple analytical method for the determination of iron (Ⅱ) in powdered milk fortified with iron (Ⅱ).It was also possible to determine iron(Ⅱ) in powder milk and other food.

Objective: To prevent the error of overcharging fees, missing fees and mistaken identity fees, check the inpatient expense rationality with using the self-developed software system. Methods:With extracting data from HIS and other systems, check and audit the inpatient expense, such as billing classification, red account records, logic checks, integrity checks, etc, according to pre-established rules. Results:Using the auditing software can greatly improve the work efficiency and the accuracy of inpatient expense, reduce the incidence of billing dispute issue. Conclusion:This system has valuable reference and be worth generalizing because it can bring the social benefit to hospital.

β-arrestins, a kind of important adaptor protein and signal transduction protein found in the purification process ofβ-adrenergic receptor kinase (β-ARK) ,were first identified as pro-teins that have the ability to desensitize G protein-coupled recep-tors ( GPCR) . Fibrosis is defined by the overgrowth, hardening, and scarring of various tissues and is attributed to excess deposi-tion of extracellular matrix ( ECM ) components including colla-gen . A large number of studies have shown thatβ-arrestins play an important role in the process of fibrotic diseases, involved in inflammatory response and excess deposition of ECM. This re-view discusses the research status and development prospects ofβ-arrestins-mediated fibrotic diseases.
