AIM: To evaluate the efficacy and the safety of betamethasone neomycin ointment in treatment of patients with subacute eczema. METHODS: The clinical trial was performed on patients with limited, subacute eczema by a randomized double blind method. Hydrocortisone neomycin ointment was chosen as controls. RESULTS: There were 45 patients involved in this study, including 23 patients in betamethasone neomycin ointment group and 22 patients in hydrocortisone neomycin ointment group. The total integra decrease of betamethasone neomycin ointment group [ 12.26 ? 2.42 to 5.61 ? 2.23 ( d 7 ), 2.83 ? 2.06 ( d 14 )] was better than that of hydrocortisone neomycin ointment group [ 13.18 ? 2.28 to 9.18 ? 3.72 ( d 7 ), 6.82 ? 3.46 ( d 14 )] on the 7th and 14th day after the treatment (P

Objectives To detect anti-basement membrane zone(BMZ)antibodies in systemic lupus ery-thematosus(SLE)patients and to explore its association with clinical manifestations.Methods Anti-BMZ anti-bodies were examined by indirect immunofluorescence in the sera of70patients with SLE.The correlation between anti-BMZ antibodies and clinical data of SLE was analyzed.Results Anti-BMZ antibodies could be found in the sera of about70%SLE patients,including IgG,IgM,IgA.They predominantly bound to the epidermis,but also bound to the dermis or both.The positive rate of anti-BMZ antibodies was significantly higher in patients with skin lesions than that of patients without skin lesions.There is no significant difference between the two groups in ac-tive and remission,kidney involvement,arthritis,alopecia,photoallergy,positive anti-dsDNA antibodies and the posi-tive rate of anti-BMZ antibodies.Conclusion Anti-BMZ antibodies presents in the sera of SLE patients with high positive rate.It is correlated with the development of skin lesions of SLE patients,but not with the activity of SLE,other clinical manifestations and anti-dsDNA antibodies.Anti-BMZ antibodies may be involved in the pathogenlic mechanism of the development of skin lesions in SLE patients.

Objective To explore the role of mouse dermis-derived mesenchymal stem cells (mdMSC) on skin repair. Methods mdMSC and human dermal fibroblasts were isolated and identified. Human dermal fibroblasts were cultured alone or eoeultured with mdMSC in Transwell chambers with the density ratio of human dermal fibroblasts to mdMSC being 2/5, 1/1, and 2/1. On day 4 and 8 of culture, the expression levels of hydroxyproline and transforming growth factor-beta (TGF-beta) 1 were measured in the supematant of monoculture and coculture by alkaline hydrolysis and ELISA respectively. Results The level of hydro-xyproline was significantly higher in the supematants of coculture system with a density ratio of 2/5 and 1/1 than that in monoculture supematants of human dermal fibroblasts on day 8 (both P < 0.05). Elevated level of TGF-betal was observed in all coculture supematants on day 8 (all P < 0.01) and in the supernatants of coculture system with a density ratio of 1/1 on day 4 (P < 0.05). There was no significant correlation between the expression level of TGF-betal and hydroxyproline in the coculture supernatants (r = 0.108, P ＞ 0.05). Conclusion In vitro coculture with mdMSC can increase the production of hydroxyproline and TGF-betal by fibroblasts, which may be a mechanism underlying the facilitation of skin repair by mdMSC.

Objective To evaluate the sensitivity and specificity of BP180NC16a-ELISA in the diagnosis of bullous pemphigoid (BP). Methods A multi-center, randomized, double-blind, parallel-controlled study was conducted. Sera were collected from 106 patients with clinically confirmed active BP and 106 control subjects including patients with non-BP bullous diseases, scleroderma, psoriasis or systemic lupus erythematosus,late pregnant women and healthy blood donors. BP180NC16a-ELISA was performed on these sera. The IgG antibody levels measured by ELISA kit were compared with those measured by indirect immunofluorescence (IIF) test. Results Of the 106 BP sera, 81 were positive for BP180NC16a-ELISA with a sensitivity of 76.4%,83 for ⅡF test with a sensitivity of 78.3%. Among the 106 control serum samples, 95 were negative for BP180NC16A-ELISA with a specificity of 89.6%, and 102 for ⅡF test with a specificity of 96.2%. There was no significant difference between the two tests in dignostic sensitivity and specificity for BP (both P ＞ 0.05).Conclusion BP180NC16A-ELISA may serve as an adjuvant tool for the diagnosis of BP.

Objective To evaluate the performance of desmoglein (Dsg)1 enzyme-linked immunosorbent assay (ELISA) in the detection of serum antibodies in patients with pemphigus foliaceus (PF). Methods Sera were obtained from 80 patients with PF and 132 human controls including 33 patients with bullous pemphigoid, 3 patients with linear IgA bullous dermatosis, 2 patients with acquired bullous epidermolysis, 20 patients with systemic lupus erythematosus (SLE), etc, and subjected to a random and blind test by Dsg1 ELISA and indirect immunofluorescence (IIF) on monkey oesophagus. Results The Dsg1 ELISA was positive in 75 (93.8%) patients with PF and 5 (3.8%) human controls (including 1 case of bullous pemphigoid, 1 case of SLE, 1 case of dermatomyositis, 1 case of eczema and 1 normal human control with indeterminate value), and IIF was positive in 71 (88.8%) patients with PF, but in none of the controls. The sensitivity and specificity was 93.8% (95% CI: 0.85 - 0.98) and 96.2% (95% CI: 0.91 - 0.99) respectively for Dsg1 ELISA in the serodiagnosis of PF, 88.8% (95% CI: 0.82 - 0.96) and 100% (95% CI: 0.96 - 1.00) respectively for IIF. There was no statistical difference in the sensitivities (P= 0.289) or specificities (P= 1.000) between the two test methods.Conclusions Dsg1 ELISA is a simple, sensitive and specific serological detection method, and can serve as an adjunct in the diagnosis of PF.

Objective To study the effects of mirabilite stuck on umbilical region combined with early enteral nutrition (EEN) on gastrointestinal function and serum inflammatory mediators in patients with mechanical ventilation. Methods Sixty-four patients with mechanical ventilation admitted to the Department of Intensive Care Unit of the Second Affiliated Hospital of Zhejiang Traditional Chinese Medical University from January to December 2016 were enrolled, and they were divided into an observation group and a control group by random number table, 32 cases in each group. The control group was treated with routine western medicine+ EEN, and the observation group was treated additionally with mirabilite stuck onto umbilical region on the basis of the treatment of the control group. The clinical effect was observed after 7 days of treatment. The differences in gastrointestinal function scores and the levels of serum inflammatory mediators were compared between the two groups before and after treatment.Results After treatment, gastrointestinal function scores of the diarrhea, bowel sound, abdominal distension and the levels of white blood cell count (WBC), serum procalcitonin (PCT), serum C-reactive protein (CRP) were decreased significantly in both groups compared with those before treatment, and the degrees of decreasing in above index levels after treatment in the observation group were more obvious than those in the control group [diarrhea: 0.72±0.03 vs. 1.59±0.21, bowel sounds: 0.87±0.05 vs. 1.54±0.18, abdominal distension: 0.77±0.04 vs. 1.63±0.09, WBC (×109/L): 9.87±1.25 vs. 12.46±2.04, PCT (μg/L): 5.43±1.02 vs. 9.65±1.63, CRP (mg/L): 56.87±4.52 vs. 89.43±8.24, allP < 0.05].Conclusion Applying mirabilite stuck on umbilical region combined with EEN can effectively promote the recovery of gastrointestinal function and significantly decrease the levels of serum inflammatory mediators in patients with mechanical ventilation.

Objective To observe the effect of early enteral nutrition (EEN) on nutritional indicators and clinical outcomes in patients with severe heart failure undergoing mechanical ventilation. Methods Thirty-four patients with severe heart failure (grade Ⅲ-Ⅳ of cardiac function) and pulmonary infections undergoing mechanical ventilation admitted to intensive care unit (ICU) of Second Affiliated Hospital of Zhejiang University of Traditional Chinese Medicine from May 2017 to April 2018 were enrolled. They were randomly divided into EEN group and delayed enteral nutrition (DEN) group. Both groups were given routine treatment, including mechanical ventilation, improvement of cardiac function, anti-infection, protection of vital organ function, regulation of blood sugar and adjustment of electrolyte and acid-base balance. The patients in EEN group received enteral nutrition (EN) within 48 hours after ICU admission, and in DEN group, EN was started after the patients had spent the early stage of stress and had stable vital signs (48 hours after ICU admission). The changes in serum B-type natriuretic peptide (BNP), C-reactive protein (CRP), nutritional indicators and liver function indicators at ICU admission and 7 days after treatment were compared between the two groups. The time needed for patients to reach EN target, duration of mechanical ventilation, length of ICU stay, and the 28-day mortality were recorded, and complications were observed. Results There was no significant difference in serum BNP, CRP, nutritional indicators or liver function indicators at ICU admission between the two groups. After treatment for 7 days, BNP and CRP in both groups were decreased significantly as compared with those at ICU admission [BNP (ng/L): 592.1±370.9 vs. 2 517.7±1 163.4 in EEN group, 621.9±418.8 vs. 2 251.5±1 006.8 in DEN group; CRP (mg/L): 46.0±19.6 vs. 59.8±22.5 in EEN group, 40.5±18.8 vs. 61.2±24.6 in DEN group, all P < 0.05], pre-albumin (PA) and transferrin (TF) were significantly increased [PA (g/L): 0.18±0.05 vs. 0.15±0.06 in EEN group, 0.17±0.04 vs. 0.12±0.06 in DEN group; TF (g/L): 1.6±0.4 vs. 1.5±0.4 in EEN group, 1.7±0.5 vs. 1.4±0.5 in DEN group, all P < 0.05]. However, there was no significant difference in the above indicators after treatment between the two groups (all P > 0.05). There was no significant change in liver function after treatment in both groups. The EN treatment was successfully completed in both groups. Some patients developed abdominal distension and diarrhea in varying degrees, which were alleviated by slowing down the infusion rate, supplemented by gastrointestinal motility drugs and intestinal flora adjustment drugs. The time needed to reach EN target in EEN group was significantly earlier than that in DEN group (hours: 42.4±10.2 vs. 53.8±17.1, P < 0.05), the duration of mechanical ventilation (days: 14.2±8.7 vs. 13.4±7.9), the length of ICU stay (days: 17.8±6.7 vs. 18.3±5.6) and 28-day mortality [5.9% (1/17) vs. 11.8% (2/17)] showed no significant difference as compared with those in DEN group (all P > 0.05), and it did not increase the incidence of aspiration pneumonia [23.5% (4/17) vs. 17.7% (3/17), P > 0.05]. Conclusion EEN could help to achieve nutritional goals as soon as possible, improve the nutritional status of the body, and provide conditions and basis for further treatment of severe heart failure patients.
