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.

Objective To investigate technique,effect,complications of limb salvage surgery for malignant tumors of the proximal tibia involving the fibula.Methods Between November 1998 and February 2010,32 patients with malignant tumors of the proximal tibia involving the fibula underwent limb salvage surgery in our institute.There were 21 males and 11 females,aged from 10 to 66 years (average,23.4years).There were 23 cases of osteosarcoma,5 cases of chondrosarcoma,1 case of malignant giant cell tumor,and 3 cases of soft tissue sarcoma.All patients received en bloc resection of tumor including proximal tibia and fibula.During operations,ligation of anterior tibial vessels was performed in 14 patients,anastomosis of posterior tibial vessels in 1 patient,both ligation of anterior tibial vessels and anastomosis or replacement of posterior tibial vessels in 5 patients.The common peroneal nerve was resected in 4 patients,and the deep peroneal nerve was resected in 5 patients.The reconstruction methods included prosthetic replacement in 24 patients,replacement with inactivated autograft-prosthesis composite in 5 patients,and replacement with inactivated autograft in 3 patients.The caput mediale musculi gastrocnemii flap was transferred to reconstruct soft tissue defect in 14 patients,while caput laterale musculi gastrocnemii flap was transferred in 1patient.Results All patients were followed up for 11 to 159 months (average,39.4 months).Local recurrence occurred in 6 patients (18.8％).The overall 5-year survival rate was 51.2％.Fourteen patients died of tumor metastasis,2 survived with tumor,and 16 patients survived without tumor.Variant complications occurred in 15 patients (46.9％).The complications included ischemia of the lower leg in 4 patients,peroneal nerve palsy in 12 patients (permanent palsy in 9 patients and temporary palsy in 3 patients),wound healing problem in 4 patients,deep infection in 1 patient,and periprosthetic fracture in 1 patient.The mean MSTS 93 score was 21.6 points (72％).Conculusion The indications of limb salvage surgery for malignant tumors of the proximal tibia involving the fibula should be restricted.Although complications are encountered frequently,most patients have acceptable postoperative function.

Objective To explore HLA-DQA1 and DQB1 alleles in their association with genetic susceptibility to psoriasis vulgaris(PV) in Han Chinese. Method Polymerase chain reaction sequence specific primers (PCR-SSP) method was used to analyze the frequencies of HLA-DQA1 and DQB1 alleles among 189 patients with PV and 273 healthy controls. Results ①HLA-DQA1*0104 and DQA1*0201 alleles were positively associated with PV (Pc

BACKGROUND:Pain is the significant cause for patients with early rehabilitation after total knee arthroplasty. Continuous epidural analgesia and continuous femoral nerve block are effective analgesic methods after total knee arthroplasty, however, which method has better effects and less complications remains controversial. OBJECTIVE:To compare the efficacy and safety of countious femoral nerve block and continuous epidural analgesia after total knee arthroplasty. METHODS:We searched Cochrane Library, PubMed, EMBASE, Web of Science, CBM, CNKI, VIP, and WangFang. Meanwhile, we also searched conference papers and academic dissertation. The retrieval time was from database establishment to October 1, 2014. Studies of randomized control ed trials on countious femoral nerve block and continuous epidural analgesia after total knee arthroplasty were included. We evaluated the quality of these included studies and analyzed data by Cochrane Col aboration’s RevMan 5.0 software. RESULTS AND CONCLUSION:A total of 12 randomized control ed trials (4 English articles and 8 Chinese articles) involving 680 patients were included. There were 343 patients with countious femoral nerve block and 337 patients with continuous epidural analgesia. Meta-analysis results revealed that no significant differences in visual analog scale scores were detected between the countious femoral nerve block and continuous epidural analgesia groups at 6, 12, 24 and 48 hours after total knee arthroplasty. However, compared with the continuous epidural analgesia group, countious femoral nerve block could decrease the incidences of nausea/vomiting (RR=0.36, 95%CI:0.21-0.63, P=0.003), urine retention (RR=0.08, 95%CI:0.04-0.16, P<0.001) and dizziness (RR=0.24, 95%CI:0.06-0.99, P=0.05). These results indicate that compared with epidural analgesia, countious femoral nerve block after total knee arthroplasty provided a strong analgesia effect, contributed to early functional training, had less adverse reactions, and was a safe and effective analgesic method.
