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.

Objective To observe the morphology of ethanol-wet dentin surfaces and detect their nano-scale adhesion force (Fad) by atomic force microscopy (AFM) in order to explore the potential mechanism of ethanol-wet bonding in improving clinical dentin bonding effectiveness.Methods Dentin slices from human premolar roots were prepared into flat ones, polished, and then randomly divided into five groups.All the specimens were acid-etched, rinsed, and left moist.They were then treated with 100% ethanol for 0s (control group), 20s, 60s, 3×60s, or stepwise ethanol application.Afterwards, each group was scanned for the morphology in air and the Fad was probed by AFM.One-way ANOVA followed by Tukey`s test was employed for multiple comparisons using SPSS16.0.Results Compared with control group, ethanol-wet dentine produced a less undulating and relatively smooth surface topography.Ethanol-wet protocol significantly decreased the value of Fad in the experimental groups (P<0.001), in which 3×60s and stepwise ethanol application groups showed the lowest Fad.No difference was found between these two groups (P>0.05).Conclusion When using AFM in air, ethanol-wet protocol with longer time can produce a less undulating and relatively smooth surface topography and decrease the Fad, whichindicates that the water saturated in dentin matrix was replaced more thoroughly by longer ethanol application time.This will benefit hydrophobicity of the dentin bonding interface.

Objective To observe the display and source of the artery located at anterolateral region next to pancreatic head on en-hanced CT,and to investigate its clinical value.Methods Imaging data of 200 consecutive patients who underwent abdominal CT scan were collected,and their CT images were analyzed.The reconstructed images were obtained at a post-processing workstation. After reconstruction,the display rate,source and branches of the artery located at anterolateral region next to pancreatic head were analyzed,and the diameters of these vessels were measured.Results The arterial vessel located at anterolateral region next to pan-creatic head was found on axial CT image in arterial phase with a display rate of 100%.By using post-reconstruction images,most vessels were gastroduodenal artery with mean diameter of 0.33 cm± 0.05 cm,and other ones were pancreaticoduodenal artery or right gastroomental artery.Conclusion The artery located at anterolateral region next to pancreatic head can be found on axial ab-dominal CT image in the arterial phase.Most vessels are gastroduodenal artery with a fixed position and traveling.

Objective To evaluate the effect of etomidate on the activity of nuclear factn kappa B (NF-κB) during lung ischemia-reperfusion (I/R) injury in rats.Methods Sixty SPF healthy adult male Sprague-Dawley rats,weighing 180-220 g,were divided into 4 groups (n =15 each) using a random number table:sham operation group (group S),lung I/R group (group I/R),etomnidate group (group E) and fat emulsion group (group F).Lung I/R was induced by 45 min occlusion of the left hilum of the lung followed by 120 min reperfusion.At 3 min before reperfusion,normal saline 1 ml was injccted via the auricular vein in I/R and S groups,and etomidate 0.3 mg/kg and fat emulsion 0.3 mg/kg (diluted to l nl in normal saline) were injected via the auricular vein in E and F groups,respectively.The rats were sac rificed at the end of reperfusion,and the lungs were removed for examination of the pathological changes (using haematoxylin and eosin staining) and for determination of the wet to dry weight ratio (W/D ratio),cell apoptosis (by TUNEL),expression of NF-κB in nucleoprotein (by Western blot) and content of tumor necrosis factor-alpha (TNF-α) in lung tissues (by enzyme-linked immunosorbent assay).Apoptotic index (AI) was calculated.Results Compared with group S,the W/D ratio,AI and content of TNF-α in lung tissues were significantly increased,and the expression of NF-κB in nucleoprotein was up-regulated in group I/R (P<0.05).Compared with group I/R,the W/D ratio,AI and content of TNF-α in lung tissues were significantly decreased,and the expression of NF-κB in nucleoprotein was down-regulated in group E (P<0.05),and no significant change was found in the parameters mentioned above in group F (P>0.05).The pathological changes of the lung were significantly attenuated in group E as compared with group I/R.Conclusion The mechanism by which etomidate reduces lung I/R injury is related to inhibition of NF-κB activity in rats.

Objective To investigate the effectiveness and safety of anterior vitrectomy combined with capsular retractor and Cionni modified capsular tension ring (MCTR) in traumatic lens subluxation surgery with anterior vitreous prolapse.Methods This study comprised 16 patients (16 eyes) of traumatic lens subluxation with anterior vitreous prolapse,in which iridodialysis was in 3 eyes,express implantation in 1 eye and Ahmed glaucoma valve implantation in 1 eye.According to the severity of lens subluxation,the patients were divided into three levels,including 90°-120° (7 eyes),120°-180° (5 eyes) and 180°-270° (4 eyes).Considering the anterior vitreous prolapse,anterior vitrectomy or/and pars plan vitrectomy was conducted with assistance of triamcinolone acetonide.After continuous curvilinear capsulorhexis,two to four capsular retractors were placed in the capsulorhexis to support and center the capsule.MCTR was inserted with scleral suture fixation after phacoemulsification.At last,the foldable IOL was implanted to capsular bag.Postoperative visual acuity,intra-and post-operative complications,anterior capsular opening,IOL positions and intraocular pressure (IOP) were assessed during 3 months' follow up.Results All patients had successfully undergone phacoemulsification,MCTR insertion and IOL implantation.Seven eyes were inserted with 2-eyelet MCTR and nine eyes were inserted with 1-eyelet MCTR.The postoperative visual acuity was better than 0.5 in 9 eyes,between 0.3 and 0.5 in 4 eyes,between 0.1 and 0.3 in 2 eyes,and less than 0.1 in 1 eye.Compared with pre-operation,the difference in the visual acuity was statistically significant (x2 =17.503,P =0.000).The scheimpflug images obtained from the Pentacam,which demonstrated that the IOL was well centered,and no MCTR and IOL decentration occurred.The common intraand post-operative complications were residual cortex,aqueous misdirection syndrome,anterior capsular tears,anterior capsular phimosis and posterior capsular opacification.Conclusion The effective application of anterior vitrectomy is the key point to reduce surgical complications.Anterior vitrectomy combined with insertion of capsular retractor and MCTR is an ideal surgical option for patients of traumatic lens subluxation with anterior vitreous prolapse.
