Abstract
The correct thoughts and principles of diagnosis and treatment of chronic refractory wounds need to be formulated. Through the relevant domestic and international consensus and based on clinical experience, the Thoughts and principles of diagnosis and treatment of chronic refractory wounds in China is proposed. It is considered that in the diagnosis and treatment of chronic refractory wounds, in the case of fully understanding the patient's medical history, the following thoughts and principles should be complied in order. (1) Pay attention to the cleanliness of the wound after being cleaned. (2) Reasonably perform debridement to avoid being " excessive" or " not thorough". (3) Reasonably perform examination, diagnosis, and differential diagnosis of pathogenic factors. (4) Treat according to etiology. (5) Find comorbidities and prevent adverse outcomes. (6) Select the correct wound treatment method reasonably and timely. When the conservative wound care treatment is considered, pay attention to embodying the concept of etiological treatment, treat the wound according to the principles of safety, phase, selectivity, and effectiveness, and make a reasonable choice of continuing conservative treatment or surgical treatment in time after completing the preparation of the wound bed. When surgical treatment is considered, pay attention to the selection of reasonable surgical method and donor site, pay attention to the healing rate of surgical wound site and the outcome of donor site, and give reasonable protection to the wound site after surgery. (7) Carry out rehabilitation treatment after wound healing and related health education.

Abstract
Objective: To explore experience of wound treatment of extremely severe mass burn patients involved in August 2nd Kunshan factory aluminum dust explosion accident. Methods: On August 2nd, 2014, 98 extremely severe burn mass patients involved in August 2nd Kunshan factory aluminum dust explosion accident were admitted to 20 hospitals in China. The patients with complete medical record were enrolled in the study and divided into microskin graft group with 56 patients and Meek skin graft group with 42 patients. Split-thickness skin in area of residual skin were resected to repair wounds of patients in microskin graft group and Meek skin graft group by microskin grafting and Meek miniature skin grafting, respectively. The residual wound size on 28 days post injury and wound infection after skin grafting of patients in the two groups, and position of donor site of all patients were retrospectively analyzed. Data were processed with t test and chi-square test. Results: The size of residual wound of patients in Meek skin graft group on 28 days post injury was (59±13)% total body surface area (TBSA), which was obviously smaller than that in microskin graft group [(70±14)%TBSA, t=4.379, P<0.05]. Twenty-nine patients in microskin graft group and 11 patients in Meek skin graft group suffered from obvious wound infection after skin grafting. Wounds of patients in two groups were repaired with residual skin around wound in head, trunk, groin, armpit, and uncommon donor sites of scrotum (4 patients), vola (10 patients), and toe or finger web (8 patients). Conclusions: Meek skin graft is the first choice for wound repair of extremely severe burn mass patients, with faster wound healing, less wound infection. Uncommon donor sites of scrotum, vola, and toe or finger web can also be used for wound repair in case of lack of skin.

Abstract
OBJECTIVE To analyze the applied condition of ovary function suppression (OFS) before and after joint analysis of TEXT and SOFT trials and SOFT trial, and to identify the relevant factors of OFS usage. METHODS The analysis was performed in premenopausal women with hormone receptor (HR) positive breast cancer receiving surgical treatment from Apr 2013 to Oct 2015 in Ruijin Hospital, Shanghai Jiaotong University School of Medicine. Adjuvant treatment strategy was made in the multidisciplinary team (MDT) meetings. We analyzed the applied condition of OFS before and after joint analysis, SOFT trial and its relevant factors. RESULTS Among 454 patients, 114 (25.1%) patients received OFS. Before the results of joint analysis came out, all the patients (38/38) received OFS together with tamoxifen (TAM); after the results came out, clinicians began to put OFS with exemestane into practice, among 76 patients, 41(53.9%) patients received OFS with exemestane while 35 (46.1%) patients received OFS together with TAM. Before the results of SOFT trial came out, 71 out of 310 (22.9%) patients received OFS while 43 out of 144 (29.9%) patients received OFS after that. No significant difference was found between the proportion of patients receiving OFS before and after the results of SOFT trial came out (P=0.112). Age, histological grade, pN status, Ki-67 status, molecular subtype and acceptance of chemotherapy were correlated with OFS treatment (P<0.05). Age, tumor grade and pN were independent significant predictors of OFS usage. CONCLUSIONS After the results of joint analysis came out, clinicians began to apply OFS with exemestane to premenopausal women with HR positive breast cancer. There is no significant difference between the proportion of patients receiving OFS before and after SOFT trial. Age, tumor grade and pN status are independent significant predictors of OFS treatment. Patients younger than 40, with histological grade Ⅱ or Ⅲ tumor and with pN1 or pN2 status are prone to receive OFS.

Abstract
Since the supply of unburned autograft skin may be insufficient to cover very extensive burns, we have prepared allograft skin inoculated with a suspension of uncultured autogenous epithelial cells and grafted this material on to full skin thickness loss wounds. There was a satisfactory 'take' and permanent healing of this mixture of heterogeneous dermis and autogenous epidermis in two out of four patients. In this preliminary report we describe the clinical and histological observations which indicate that in the two patients with successful graft 'take' the epithelial cells proliferated and formed a continuous pale-coloured layer on top of the heterogeneous dermis between 30 and 40 days after application.
