Photocrosslinking silver nanoparticles-aloe vera-silk fibroin composite hydrogel for treatment of full-thickness cutaneous wounds.

Damage to the skin causes physiological and functional issues. The most effective treatment approach is the use of wound dressings. Silk fibroin (SF) is a promising candidate biomaterial for regulating wound healing; however, its antibacterial properties and biological activity must be further improved.

[Comparison of recurrence and complication by different thyroidectomy in the treatment of differentiated thyroid carcinoma as initial treatment: a meta-analysis].

Objective: To compare the total thyroidectomy or subtotal resection and gland lobe and isthmus lobectomy as initial treatment to TNM stage I and II differentiated thyroid cancer. The difference between recurrence rate and surgical complications were analysed.

Methods: The literatures published between 1972-2012 were searched in Pubmed, Medline, Wanfang database, Chinese Biomedical Literature Database, Chinese scientific Journals database and China National Knowledge Infrastructure.

Systematic evaluation on the use of acellular dermis matrix graft in prevention Frey syndrome after parotid neoplasm surgery.

Objective: To study the effectiveness and safety of acellular dermal matrix (ADM) graft in preventing Frey syndrome after parotid neoplasm surgery, we reviewed foreign reported clinical randomized controlled trials systematically. Based on this review, we aimed to assess the effectiveness of ADM graft and provide reliable evidence for clinical application.

Methods: We reviewed foreign-language databases, such as MEDLINE, applied meta-analysis with Rev.

Epidemiology of esophageal cancer in Yanting - regional report of a national screening programme in China.

Background And Objectives: Yanting in Sichuan Province is one of the highest risk areas of esophageal cancer (EC) in the world. We here summarize the epidemiology of EC in Yanting using data from the national screening programme during 2006-2011.

Methods: Random cluster sampling was used to select a proportion of natural villages from six towns in Yanting, and residents aged 40-69 years old were invited for screening.

Angiopoietin-2 expression is correlated with angiogenesis and overall survival in oral squamous cell carcinoma.

This study sought to determine the expression of angiopoietin-2 (Ang-2) and vascular endothelial cell growth factor (VEGF) in oral squamous cell carcinoma (OSCC) and assess their correlations with tumor progression, angiogenesis, vessel maturation, and clinical survival. Tumor tissue from 102 OSCC patients, adjacent noncancerous oral tissue from 79 OSCC patients, and normal oral mucosa from 35 control patients were examined for Ang-2 and VEGF expression using conventional immunohistochemistry. Microvessel density (MVD) and vessel maturation index (VMI) were assessed by double-label immunohistochemistry staining using anti-CD34 and anti-alpha-smooth muscle actin, respectively.

[Results of a screening program on high incidence area of esophageal cancer in Yanting Sichuan from 2006 to 2011].

Objective: To study the prevalence of esophageal cancer and various lesions of esophagus in high risk areas through a screening program for early diagnosis and treatment.

Methods: Random cluster sampling method was used to select some portions of a natural village as screening object in the high risk areas of esophageal cancer, from 2006 to 2011. Endoscope iodine staining and index biopsy screening methods were used on people with high risk and followed by pathological exams for confirmation.

[Evidence for determining the safe surgical margin for pleomorphic adenoma of parotid gland].

Objective: To compare the treatment outcomes, complications and histopathologic features between conventional parotidectomy and functional regional parotidectomy in the treatment for pleomorphic adenoma of parotid gland and to provide clinical, and pathological evidence for determining the safe surgical margin.

Methods: Of 109 patients, 60 patients received conventional parotidectomy and 49 patients received functional regional parotidectomy. The rates of tumor recurrence and complications were compared between the groups of patients.

[Meta-analysis of surgical techniques for preventing Frey syndrome and a concave facial deformity after parotidectomy].

Objective: To explore the curative effects on surgical methods for the prevention of Frey syndrome and a concave facial deformity after parotidectomy.

Methods: A literature search was performed using the Wianfang Database, Chinese Biomedical Literature Disk Database, Chinese Digital Hospital Library and Chinese Scientific Journals Database of VIP from January 1989 to December 2008. Twenty-six Chinese language controlled studies involving surgical techniques for prevention of Frey syndrome and the concave facial deformity after parotidectomy were identified.
