Objective To investigate the cognition of nurse groups toward nurses' dual practice,and to analyze nurses' tendency to pursuc dual practice and its influencing factors.Methods A questionnaire survey was conducted,and 1010 registered nurses were recruited using stratified sampling method.Results Most (76.4％) nurses agreed with nurses' dual practice.The willingness about nurses' dual practice was significantly different(P=0.022,P=0.008) due to different age and length of service.The top three benefits of nurses' dual practice were to increase reasonable salary of nurses,improve quality of nursing care in community institutions for the aged and increase the utilization of health care resource.As for the disadvantages,disrupting the medical and nursing order,increasing difficulties of management and government's supervision,increasing medical risks.Nurses believed that the main obstacles for nurses' dual practice were the unclear medical risks and the unprotected nurses' interests.Conclusion The nurse groups had a positive and optimistic attitude towards nurses' dual practice.In the case that the government implements relevant laws and regulations,and the interests of nurses are well-guaranteed,nurses' dual practice is a good measure that can improve nurses' work motivation.

In the therapeutic application of head and neck squamous cell carcinoma ( HNSCC),S-1 is used to combine with other chemotherapeutics or even with radiotherapy to constitute chemoradiotherapy regimens.Adverse effects are well tolerated.Regimens containing S-1 are wildly used to control distant metastasis as well as local recurrence.The studies of treatment also show good application value.

Objective To discuss the difference of levels of serum and urinary iodine and thyroid function in painless thyroiditis patients and other thyroiditis patients.Methods The patients who were preliminary diagnosed as having higher level of serum thyroid hormone were divided into Graves' disease group,subacute thyroiditis group and painless thyroiditis group.Then all the patients were divided into another two groups according to the level of autoantibody.The value of serumal thyroid hormone and serumal iodine and urinary iodine were measured and the relationship between the groups and the value were observed.Results There was close relationship between serum T 3,T 4,urinary iodine and the types of thyrotoxicosis.Conclusion The morbidity of painless thyroiditis is not uncommon.Clinical situation,serumal iodine,urinary iodine and serumal thyroid hormone may be useful for clinical diagnosis and differential diagnosis of painless thyroiditis.

WHO proposed the concept of intrinsic capacity in the World Report on Aging and Health in 2015.As the basis of functional ability in the elderly, intrinsic capacity plays an important role in maintaining the quality of life and promoting healthy aging.However, research on intrinsic capacity is still in its infancy.This article reviews research progress on intrinsic capacity, including the concept, domains, screening methods and its impact on the health of the elderly, in order to provide a reference for further research on this subject.

Objective To provide anatomical basis for the free saphenous branch of descending genicular artery flap and evaluate its clinical outcomes for the hand soft-tissue defects. Methods Fifteen fresh cadavers injected with lead oxide-gelatin mixture for three-dimensional visualization reconstruction using a spiral computed tomography scanner. The origin, course and distribution of the perforators of descending genicular artery were observed.From January 2005 to October 2011,seven patients with skin defect on the distant limbs were treated.The flap size was 5 cm × 6 cm-11 cm × 14 cm,vascular pedicle length 5.4 (4-7)cm. ResultsThe saphenous branch was consistent. It arised from the descending genicular artery (68％) or femoral artery(32％).The diameter of the saphenous branch was 1.5(1.1-1.7)mm at its origin above 9.0(4.0-16.0)cm from the medial epicondylar.Seven cases of flaps all survived,the average followup of 28 months,close to hand flap of skin texture,some sensory recovery,two-point discrimination 8-12mm. Conclusion Free saphenous branch of descending genicular artery flap is a reliable option for the treatment of soft tissue defect in hands. The pedicles were invariable of anatomy, thickness of the flaps is comparable,and procedure is simple and time saving.

Objective To establish a model of embryonic stem cell test(EST)and utilize this model to evaluate the embryotoxici-ty of hydroquinone.Methods Mouse 3T3 fibroblasts and mouse embryonic stem(ES)cells(ES-E14TG2a)were cultured in vitro, and methyl thiazolyl tetrazolium(MTT)test was performed to detect the cytotoxicity of 3T3 cells and ES-E14TG2a cells induced by the positive control(5-fluorouracil),negative control(penicillin G)and tested compound(hydroquinone).The concentrations of the test compounds that inhibited 50% viability of ES-E14TG2a cells(IC50 ES)and 3T3 fibroblasts (IC50 3T3)were calculated.The hanging-suspension-adherent culture systems were used to induce embryonic stem cells into cardiomyocytes,and the concentrations of test compounds that caused 50% inhibition of differentiation of ES-E14TG2a cells into cardiomyocytes (ID50 ES)was calculated. The embryotoxic potential of hydroquinone was classified by prediction model of the embryonic stem cell test.Results The prolif-eration of ES-E14TG2a and 3T3 cells were inhibited by hydroquinone,of which the IC50 3T3 and IC50 ES values were (5.97±0.48) and (2.57±0.10)μg/mL respectively.The differentiation of ES-E14TG2a cells were also inhibited by hydroquinone,of which the ID50 ES was (3.77±0.31)μg/mL.Hydroquinone was evaluated as a strong embryotoxicity chemical by prediction model of EST. Conclusion Hydroquinone exhibits a strong embryotoxicity.

Recently, drug delivery materials have become the hotspot of medical study. Suitable delivery material plays an important role in constructing an excellent drug delivery system. Silk fibroin is a naturally occurring protein polymer with excellent biocompatibility, remarkable mechanical properties, biodegradability and outstanding processability. Due to its unique properties, silk fibroin has become a favorable carrier material for the incorporation and delivery of a range of therapeutic agents. Based on the structure and characteristics of silk fibroin, this article provides an overview of the recent research progress of silk fibroin used as drug delivery materials.
