Objective To explore the optimal method of qualitative and quantitative assessment of retinal neovascularization(RNV),choroidal neovascularization(CNV) and leakage from CNV. Methods Thirteen mice were randomly divided into RNV assessment group(n=7)and CNV assessment group(n=6).For RNV assessment, 3 mice were served as normal controls,and the other 4 were made into models of retinopathy of prematurity(ROP).At postnatal d16,mice in normal control group and 3 ROP model mice received intraocular injection with FITC labeled or unlabeled antibody and were sacrificed 12 h later.The retinas were flat mounted(FITC labeled antibody) or incubated with secondary antibody(unlabeled antibody) and then flat mounted.The other ROP model mouse was served as blank control.For assessment of CNV and leakage from CNV,6 mice(12 eyes) were induced into models of CNV,and were randomly divided into two groups.Seven and 14d after model establishment,mice were intraocularly injected with unlabeled antibody,and fluorescein sodium were intraperitoneally injected 12 h later.The area of CNV and that of CNV leakage were calculated. ResultsRetinas from eyes injected with FITC labeled antibody exhibited good resolution of ultrastructure of RNV,while retinas from eyes injected with unlabeled antibody showed selective staining of RNV with no background,greatly facilitating identification and quantification of RNV.Merging images of stained CNV with images of fluorescein sodium leakage from CNV revealed double labeled CNV surrounded by fluorescein that had leaked into surrounding tissues.The mean area of CNV and its leakage of d14 were significantly different from those of d 7(P

OBJECTIVETo study the clinical effects of gabapentin on the treatment of pruritus of scar resulting from deep partial-thickness burn.
METHODSA total of fifty-eight patients suffering from pruritus of scar after deep partial-thickness burn were hospitalized from January 2013 to January 2014. Patients were divided into placebo group (n =18, treated with oral vitamin C in the dose of 100 mg for 4 weeks, twice per day) , cetirizine group (n = 20, treated with oral cetirizine in the dose of 10 mg for 4 weeks, twice per day) , and gabapentin group (n = 20, treated with oral gabapentin in the dose of 300 mg for 4 weeks, twice per day) . Before treatment and on post treatment day (PTD) 3 and 28, the Visual Analog Scale (VAS) was used to assess the itching degree, and the mean scores were recorded. The remission rates of pruritus on PTD 3 and 28 were calculated. The adverse effects were observed during treatment. Data were processed with analysis of variance, q test, and chi-square test.
RESULTSCompared with that before treatment, the itching degree of patients with light, moderate, and severe itching in placebo group was not relieved after treatment; the itching degree of patients with moderate or severe itching in cetirizine group was alleviated after treatment, but not in patients with light itching; itching degree of all patients in gabapentin group was significantly relieved after treatment. There were no obvious differences in VAS scores among the 3 groups before treatment (F = 2.78, P > 0.05). On PTD 3 and 28, the VAS scores of patients in both gabapentin group [(2.3 ± 0.8) and (0.6 ± 0.3) points] and cetirizine group [(4.2 ± 1.7) and (2.8 ± 1.2) points] were lower than those in placebo group [(5.7 ± 2.0) and (5.7 ± 1.9) points, with q values from 6.70 to 7.75, P values below 0.05]. The VAS scores of patients in gabapentin group on PTD 3 and 28 were lower than those in cetirizine group (with q values respectively 6.30 and 6.90, P values below 0.05). The remission rates of pruritus of patients in gabapentin group on PTD 3 and 28 were respectively (66 ± 20)% and (91 ± 17)%, and they were higher than those in cetirizine group [(33 ± 8)% and (56 ± 14)%, with q values respectively 4.70 and 3.82, P values below 0.05]. The remission rate of pruritus of patients in placebo group on PTD 3 and 28 was 0, which was lower than that of the other 2 groups each (with q values from 3.94 to 6.76, P values below 0.05). During the course of treatment, 5 patients in gabapentin group suffered from adverse effects including mild-to-moderate drowsiness and dizziness, but they disappeared one week later. No adverse effects were observed in patients of the other two groups.
CONCLUSIONSFor patients with deep partial-thickness burn, gabapentin can effectively alleviate scar itching after wound healing with safety.

Objective To investigate the effect of continuous renal replacement therapy on the levels of IL-27 in peripheral blood of patients with chronic heart failure concurrence acute kidney failure. Methods 78 patients with chronic heart failure were enrolled from June 2012 to December 2013 in Zhujiang hospital affiliated Southern medical university. According to patient′s condition, 38 patients with chronic heart failure concurrence acute kidney failure undertaking CRRT, 40 patients with chronic heart failure undertaking conventional therapy. Heart function were determined by cardiac ultrasound, the levels of IL-27 and BNP were determined by ELISA. Results Compared with chronic heart failure patients, the levels of IL-27 were decreasing but BNP were increasing in patients with chronic heart failure concurrence acute kidney failure (P < 0.05). After CRRT, the levels of IL-27 were increasing but BNP were decreasing in patients with chronic heart failure concurrence acute kidney failure. Correlation analysis showed that the levels of IL-27 is negatively correlated with the levels of BNP , but positively correlated with LVEF (P<0.05). Conclusion IL-27 participated in the development of chronic heart failure concurrence acute kidney failure. CRRT regulating and controlling the heart and kidney function may partly through effecting on immune-inflammatory mechanism.

Objective To evaluate the effect of various herniorraphy in treating inguinal hernia. Methods The clinical data of 108 patients who underwent conventional Bassini herniorraphy (BH), tension free herniorraphy (TH), or laparoscopic herniorraphy (LH),respectively were analysed and comparated. Results The operation time in TH was less than that in BH, and in LH was longer than that in TH. The ability recovery, hospita stay and postoperative complication in TH and LH were less than those in BH.All the patients were followed up for at least 1 year.Of them, 1 recurred after BH, but there was no recurrence after TH and LH. The blood neutrophils, serum level of fibrin, C-reactive protein and alpha-1 antitrypsin increased significantly in the patients undergoing herniorraphy, which were significantly higher in the patients underwent TH and LH. Conclusions The curative effect of TH and LH is much better than that of BH in treating ingumal hernia. Application of marlex for herniorraphy might increase inflammation response, but it will not increase the incidence of infection.

Exposure to low-dose radiation (LDR,mostly less than 100 mGy) may reduce the vulnerability of exposed tissues to subsequent high-dose radiation (HDR)-induced damage,a phenomenon known as adaptive responses,which occurs via mechanisms including anti-inflammation and anti-oxidation.Alzheimer's disease (AD) is a type of dementia that causes problems with memory,thinking,and behavior.Using the available literature,this review will examine whether there is any effect of LDR on AD.The available evidence shows that although LDR can alter the expression of some genes related to AD such as Apbb1,Lrp1,and Il1α,these alterations do not cause AD-like syndromes in animals,suggesting that LDR may also simultaneously upregulate several protective mechanisms that prevent the eventual development of AD.Furthermore,LDR seems capable of improving the symptoms of AD,as evidenced by the experience of an 81-year-old female AD patient.This patient was diagnosed with AD more than 10 years ago and gradually progressed to advanced AD in 2015,despite routine treatment.The patient then received about 12 computed tomography scans (about 40 mGy each) up until Nov.2017,which significantly improved her quality of life and reduced several AD symptoms.The improvement in this patient's medical condition led to a few recent clinical trials investigating the effects of LDR on AD.To date,there is no efficient therapy available for AD,thus whether exposure to LDR at 100 mGy can provide a preventive or therapeutic effect for AD is an important issue.If LDR is a potential treatment for AD,as suggested by this reported case,this non-invasive approach would also bear the merit that it would be unlikely to cause a significant radiation health risk,as the LDR could be delivered locally to the head without any impact on other organs.
