Hereditary disease, especially monogenic disease is one of the major causes for malformation and disability of children. Most hereditary diseases have no effective therapy besides clinical symptomatic treatment. Biological techniques targeting casual genes or related signaling genes, such as transgenic, RNA interfere, genome editing, have been successfully applied in treating some hereditary diseases. However, most biological, treatments were carried out in animals, further confirmation of the effectiveness and safety of these therapies, and development of more therapeutic approaches based on mechanisms are needed before clinical trials.

This paper introduces the nursing care for 36 patients with framework exposure in auricular reconstruction by temporal superficial fascia flaps combining with split skin grafts transplantation,such as pre-and post-operative behavioral in-struction,psychological care,and close observation of blood circulation of reconstructed auricular. The patients' wounds healed up well and all the split skin grafts survived successfully. No infection and stent exposure occurred once more. The appear-ance of the reconstructed auricular was pleasing too. It is suggested that high quality of pre-and post-operative nursing,care-ful health education and psychological care be beneficial for the successful repair of framework exposure after auricular recon-struction.

Aim To investigate the roles of intracellu-lar reactive oxygen species ( ROS ) and Nrf2 pathway in shikonin-induced A549 cell apoptosis. Methods The cytotoxicity was analyzed by MTT assay. The ap-optosis of A549 cells was analyzed by both cellular morphological and biochemical methods. The relative changes of the redox marks ( ROS/GSH) were studied by fluorescence assay in the shikonin-treated A549 cells in accompany with the changes of the intracellular redox homeostasis by GSH/GSSG ratio. ROS inhibitor was also employed in the treatment to find the role of ROS in shikonin-induced A549 cell apoptosis. Real-time PCR analysis and ELISA assay were performed as well to determine the role of Nrf2 pathway in the shiko-nin-induced A549 cell apoptosis. Results The IC50 of shikonin on A549 cells was 3. 2 mg·L-1 . The cellu-lar redox homeostasis shifted toward oxidation signifi-cantly in shikonin treatment in a time-dependent man-ner. The expression of the Nrf2 pathway related genes was up-regulated by shikonin ( 3 . 2 mg · L-1 , 8 h ) . The expression of the anti-apoptotic genes was down-regulated , and proapoptotic genes were up-regulated by shikonin (3. 2 mg·L-1, 24h). Futhermore, the inhi-bition of intracellular ROS alleviated the cytotoxicity of shikonin in A549 cells. Conclusion The critical role of shikonin-induced redox imblance in A549 cell, coped with the secondary produced ROS and Nrf2 path-way antioxidants, result in A549 cell apoptosis.

OBJECTIVE:To provide empirical reference for protecting the supply of clinical drugs. METHODS:Literature re-view was combined with the conditions of drugs that lost the bidding in the centralized bidding in Anhui province to determine the short drugs need to investigate. Questionnaire was adopted to investigate the situations and reasons of short drugs in 5 third-grade class-A hospitals of 5 areas in Anhui province from Nov. 2013 to Oct. 2014. RESULTS:A total of 5 questionnaires were sent out, and 5 were received with effective response rate of 100%. There were totally 54 short drugs in the 5 third-grade class-A hospitals, including the most serious shortage of drugs for neurocirculatory system,accounting for 20.37%. Shortage was mainly due to the low price of drugs,accounting for 48.15%,and insufficient supply,less suffering patients/low dosage and other reasons. CON-CLUSIONS:In view of the shortage of drugs,government departments should improve the drug pricing and bidding policy,pro-duction enterprises should enhance the enterprise production and development capabilities,business companies should optimize the distribution pattern of network and medical institutions should establish drug management system with a clear division of power and responsibility to relieve the drug shortages.
