Objective To develop a liquid bandage for self aid of war wound.Methods Solution A and B were prepared containing functional polymers derived from the biocompatible poly (ethylene glycol) and hyaluronic acid,which had ability of fast crosslinking reaction when they were mixed.Among them,A solution mainly comprised of mercapto group-containing hyaluronic acid derivative (HA-SH),water-solubility starch,propylene glycol,benzoic acid and etc.B solution contained pentaerythritol tetraacrylate derivative (4arm-PEG-Acrylate) and benzoic acid.The structure of mercapto group-containing hyaluronic acid derivative was confirmed by IR,1H-NMR and etc.HA-SH and 4arm-PEG-Acrylate were formulated to different concentrations (W/V) in different buffers.The two kinds of solution were mixed in different ratios,and in situ crosslinking hyaluronic acid hydrogel was obtained;the crosslinking time was recorded.The adhesive force and waterholding capacity of the hydrogel after crosslinking were measured by adding excipients such as water-solubility starch.Results In case the concentration of HA-SH and 4arm-PEG-Acrylate was 2％ and pH value was 11,the hydrogel film on wound skin would be quickly formed in 20 seconds for wound dressing after spraying A and B solution onto the wound skin.Conclusion The liquid bandage has strong adhesive force,high water-holding capacity and controllable crosslinking time,so it could be used as a novel wound dressing for war wound.

The purpose of this study was to evaluate the effect and safety of Jinlong capsule combined with chemotherapy or radio-therapy for non-small cell lung cancer (NSCLS) using Meta-analysis. PubMed, Embase, CNKI and Wanfang databases were all searched without language restriction, and searching time was from January 1990 to July 2015. All eligible published studies were included in this study for quality assessment and data extraction. All the data were analyzed using Revman 5.3. A total of ten studies including 736 subjects (370 in Jinlong capsule plus chemoradiotherapy and 366 in chemoradiotherapy only) were finally included in this Meta-analysis. The result of Meta analysis showed that compared with pure chemoradiotherapy group, Jinlong capsule combined with chemoradiotherapy for NSCLC could improve the patients' curative effect (OR = 1.77, 95% CI: 1.29-2.43, P < 0.05), clinical benefit rate (OR = 1.89, 95% CI: 1.22-2.91, P < 0.05), life quality improvement rate (OR = 2. 56, 95% CI: 1.61-4.05, P < 0.05), and decrease leucopenia incidence rate (OR = 0.35, 95% CI: 0. 22-0.56, P < 0.05) and gastrointestinal reaction rate (OR = 0.67, 95% CI: 0.40-1.11, P < 0.05). The pooled results showed that Jinlong capsule combined with chemoradiotherapy for NSCLC could improve the curative effect and life quality, and decrease the adverse reaction of patients.

Epmedii Folium is a commonly used traditional Chinese drug, and is beneficial for the "liver" and "kidney" s function in Chinese medicine. Recently, the origin of this drug is more complex. Most of the identification studies are emphasized on the species certified by the pharmacopoeia and other related species from the same genus of Epimedium, but few was emphasized on the counterfeit. In this paper, one counterfeit of Epmedii Folium, identified as the dried leaf of Quercus variabilis (Fam. Fagaceae), has been reported based on field investigation, comparing specimen of Epmedii Folium and Q. variabilis,using the macroscopic, microscopic and TmC methods. It is resulted that they could be identified clearly not only by the macroscopic features, such as the vein character and the tooth apex, but also by the microscopic features, such as the vascular bundles of the midrib, the non-glandular hair, the anticlinal wall of the epidermis cell and the calcium oxalate crystal. Furthermore their TLC chromatograms showed also difference. This study will give reference for the identification of Epmedii Folium and the related supervision and inspection work.
