This report summarized the nursing experience of caring for twice skin grafts in a patient with enteroatmospheric fistula after trauma.Keys to nursing success including:monitoring vital signs closely to prevent septic shock,blocking enteroatmospheric fistula (EAF) and sucking overflowed intestinal juice timely,promoting the protection of the graft on abdominal wall wounds,strengthing drainage and lavage with the application of abdominal double cannula to control abdominal infection,early nutrion support with parenteral nutrition in combination with trophic enteral nutrition to improve intestinal immune function,and attaching importance to post-traumatic stress disorder.Timely blocking of EAF is the bases of skin graft healing.

Objective:To investigate the effects of anemoside B4 on apoptosis of retinal cells in diabetic rats.Methods:Sixty Sprague-Dawley rats were randomized into three groups: the normal control(control), diabetic rats(DM)and diabetic rats treated with Anemoside B4(B4)groups(n=20, each group). Rats in the DM and B4 groups were rendered diabetic with an intraperitoneal injection of streptozotocin(STZ, 60 mg/kg). After 3 days of successful modeling, rats in the B4 group were intraperitoneally injected with anemoside B4(5 mg/kg), twice/day, for 8 weeks, while rats in the control and DM groups were injected with an equivalent volume of normal saline.After 8 weeks of anemoside B4 and normal saline injection, rats were sacrificed and retinas were harvested for examination.Paraffin sections of retina were stained with the hematoxylin-eosin(H-E)method for morphological evaluation.Protein levels of Bax and Bcl-2 were detected by using Western blot.The expression of caspase-3 mRNA was detected with quantitative PCR.Results:H-E staining results showed the control group had intact retinal structure and clear morphological features, whereas disordered retinal structure, thinner layers, and sparse and disorganized cells were seen in the DM group.However, retinal structure and morphology were improved after treatment with anemoside B4.Compared with the control group, the protein expression of Bcl-2 was lower( t=57.81, P<0.01), the protein expression of Bax was higher( t=10.47, P<0.01), and the Bcl-2/Bax ratio was lower( t=23.98, P<0.01)in the DM group.Compared with the DM group, the protein expression of Bcl-2 was higher( t=41.07, P<0.01), the protein expression of Bax was lower( t=6.811, P<0.01), and the Bcl-2/Bax ratio was higher( t=14.70, P<0.01)in the B4 group.Caspase-3 mRNA expression was higher in the DM group than in the control group( t=7.916, P<0.01), but was lower in the B4 group compared with the DM group( t=6.221, P<0.01). Conclusions:Anemoside B4 can inhibit the apoptosis of retinal cells by up-regulating Bcl-2 expression and down-regulating Bax and caspase-3 expression in diabetic rats.

The ultrasonic manifestations of benign and malignant breast imaging-reporting and data system(BI-RADS)4 lesions overlap in some degrees,is able to result in unnecessary biopsy or untimely therapy.Accurate classifying the nature of BI-RADS 4 breast lesions can provide reliable references for clinical decision-making.The progresses of application of new ultrasonic technologies,including automated breast volume scanner,superb micro-vascular imaging,elastography,contrast-enhanced ultrasound and artificial intelligence for assisting diagnosis of BI-RADS 4 lesions were reviewed in this article.

OBJECTIVE：To provide reference for improving medical insurance reimbursement for multi-indication drugs based on value-based pricing in China. METHODS：The theory and practice of value-based pricing for multi-indication drugs were sorted out，and the value standards and medical insurance reimbursement strategies based on value-based pricing in France，Germany，UK，Italy and Sweden were analyzed，so as to provide the suggestions for medical insurance reimbursement of multi-indication drugs in China. RESULTS & CONCLUSIONS：The realization of value-based pricing first needed to develop a value framework to define，measure and integrate value，and then established a model to convert the total value into price. The overall idea of value-based pricing for multi-indication drugs was consistent，but there were differences in the value standard. In the UK and Sweden， quality-adjusted life years （QALYs） and incremental cost-effectiveness ratios （ICERs） measured by pharmacoeconomicsare used as the value standard. France，Germany and Italy were more focused on the therapeutic value and clinical benefit improvement. As for medical insurance reimbursement strategies，France adopted single weighting method based on expected volume. Germany adopted combination weighting method based on value and volume. UK introduced the Patient Access Schemes and Italy introduced the Managed Entry reements，both based on the nominal reimbursement standard. Sweden adopted independent reimbursement for different indications by different brand names. It is suggested that China can explore the value-based pricing strategies of multi-indication drugs on the basis of the above international experiences，reference and use these variety of medical insurance reimbursement strategies comprehensively. Simultaneously，the information collection mechanism of patients and drug use should be improved to provide data support for the implementation of China’s value-based pricing and reimbursement strategies for multi-indication drugs.
