Objective To estimate the performance of Wood's lamp examination in the diagnosis of superficial cutaneous fungal infections. Methods Totally, 129 patients, who were diagnosed with superficial cutaneous fungal infections according to clinical medical history and signs, were enrolled in this study. Wood's lamp examination of lesions was carried out. Cutaneous samples were obtained from the patients and subjected to microscopic examination and fungal culture. Results Wood's lamp examination was positive in 84% and 85.7% of patients with tinea versicolor and malassezia folliculitis, respectively; among these patients positive for Wood's lamp examination, 92.9% were positive for fungal culture, and 87.5% for microscopic examination. In patients clinically diagnosed with tinea manus and pedis, tinea corporis or tinea cruris, 8.3% were positive for Wood's lamp examination, while 85.4% were positive for fungal examination. There was a high consistency between Wood's lamp examination and fungal examination in patients with tinea versicolor and malassezia folliculitis, but not in those with tinea manus and pedis, tinea corporis or tinea cruris. Conclusions Wood's lamp examination shows a high specificity and sensitivity and is useful in the diagnosis of tinea versicolor and malassezia folliculitis, but seems unapplicable for the diagnosis of tinea manus and pedis, tinea corporis or tinea cruris.

Objective: To analyze the processing situation of 124 batches of scorpions and optimize the salt-water processing.Methods: The character, extract, moisture, total ash, acid insoluble ash, amino acids content and heavy metals in the marketed scorpions were determined.Using extract and amino acids contents as the indices, the salt-water processing was optimized.Results: The results of the above determinations showed that the quality difference was very obvious for the marketed scorpion, and the extract and amino acids contents were the highest in scorpion boiled in 2% sodium chloride aqueous solution for 5 min.Conclusion: The item of extract test should be revised in the current standard, and the items such as moisture, total ash, acid insoluble ash, amino acids content and heavy metals should be taken into consideration in order to control the quality of scorpion more comprehensively.The best salt-water processing of scorpion is boiled in 2% sodium chloride aqueous solution for 5 min.

Objective To explore the effects of early enteral nutrition (EN) combined with probiotics on intestinal flora and immune function in patients with severe ischemic stroke. Methods Sixty-nine severe ischemic stroke patients were admitted and continuously enrolled in Taizhou First People's Hospital from June 2017 to June 2018, and they were randomly divided into an EN combined with probiotics group (35 cases) and a simple EN group (34 cases). Early EN support was given to both groups and probiotics (Live Combined Bifidobacterium, Lactobacillus and Enterococcus capsules) was added to the EN combined with probiotics group, 0.42 g each time, 3 times a day for 14 days. The changes of serum inflammatory markers [hypersensitive C-reactive protein (hs-CRP), procalcitonin (PCT), tumor necrosis factor-α (TNF-α), interleukin-10 (IL-10)], intestinal flora (Bifidobacterium, Lactobacillus, Clostridium, Enterobacter, Enterococcus, Bacteroides), intestinal mucosal barrier [endotoxin, D-lactic acid, diamine oxidase (DAO), intestinal fatty acid binding protein (I-FABP) ], and immune indexes [immunoglobulins (IgA, IgG, IgM), human leukocyte DR antigen (HLA-DR)] were observed in two groups of patients after treatment. Results With the prolongation of time, Bifidobacteria, Lactobacilli, HLA-DR and IgA, IgG, IgM after EN in both groups all decreased first and then had a tendency of increase, all reaching the lowest value on the EN 3rd day and then gradually elevated arriving at the peak value on the EN 14th day, and the levels in EN combined with probiotics group were significantly higher than those in the simple EN group [Bifidobacterium (×107 cfu/g): 8.31±1.49 vs. 7.49±1.32, Lactobacillus (×107 cfu/g): 8.04±1.45 vs. 7.19 ±1.37, HLA-DR: (67.22±9.11)% vs. (61.21±9.69)%, IgA (mg/L): 170.34±40.13 vs. 149.54±38.76, IgG (g/L):4.88±0.88 vs. 4.31±0.86, IgM (mg/L): 879.47±100.82 vs. 821.52±97.75, all P < 0.05]. With the prolongation of time, the Clostridium, Enterobacter, Enterococcus, Bacteroides, hs-CRP, PCT, TNF-α, endotoxin, D-lactic acid, DAO, I-FABP after En in both groups all increased first and then had a tendency of decrease, reaching the highest level on the EN 3rd day, then gradually decreased arriving at the valley value on the EN 14th day, and the levels in the EN combined with probiotics group were significantly lower than those in the simple EN group [Clostridium (×107 cfu/g): 5.23±0.87 vs. 5.79±0.91, Enterobacter (×107 cfu/g): 7.45±1.21 vs. 8.62±1.32, Enterococcus (×107 cfu/g): 7.32±1.05 vs. 8.12±1.23, Bacteroides (×107 cfu/g): 9.16±1.35 vs. 9.87±1.42, hs-CRP (mg/L): 18.45±12.98 vs. 25.47±15.55, PCT (ng/L): 3.24±1.21 vs. 4.18±1.32, TNF-α (ng/L): 9.43±8.69 vs. 13.59±9.45, IL-10 (μg/L): 39.45±10.72 vs. 48.52±11.42, endotoxin (U/L): 6.74±2.12 vs. 9.21±3.28, D-lactic acid (mg/L): 98.74±20.74 vs. 114.78±19.89, DAO (mg/L): 21.45±8.49 vs. 29.47±9.41, I-FABP (ng/L): 1.4±0.2 vs. 1.5±0.2, all P < 0.05]. Conclusion Early EN combined with probiotics can effectively regulate the intestinal flora and intestinal mucosal barrier function, reduce the level of inflammatory response and enhance the body immunity in patients with severe ischemic stroke.

Background: Recent studies have found that there are significant associations between body iron status and the development of diabetes. In the present study, we aimed to analyze the association among iron overload (IO), insulin resistance (IR), and diabetes in Chinese adults, and to explore the sex difference. Methods: Men and women (age >19 years) who participated in the Chinese Health and Nutrition Survey and did not have diabetes at baseline were followed between 2009 and 2015 (n=5,779). Over a mean of 6 years, 75 participants were diagnosed with incident diabetes. Logistic regression was used to assess the risk factors associated with IO. Cox proportional hazard regression was used to estimate the risk of incident diabetes and to determine whether the risk differed among subgroups. Causal mediation analysis (CMA) was used to explore the mechanism linking IO and diabetes. Results: According to sex-stratified multivariable-adjusted Cox proportional hazards regression, IO increased the risk of incident diabetes. Women with IO had a higher risk of diabetes than men. Subgroup analysis with respect to age showed that the association between IO and diabetes was stronger in older women and younger men (P<0.001). CMA showed that liver injury (alanine transaminase) and lipid metabolism abnormalities (triglyceride, apolipoprotein B) contributed to the association between IO and diabetes. Conclusion IO is associated with diabetes and this association is sex-specific. IO may indirectly induce IR via liver injury and lipid metabolism abnormalities, resulting in diabetes.
