ABSTRACT
@#Objective To observe the effect of hyperbaric oxygen chamber treatment on the expression of autophagy protein microtubule associated protein 1 light chain 3 (LC3) and Beclin-1 in cerebral vascular endothelial cells of rats with ischemia-reperfusion injury, and to explore the mechanism of hyperbaric oxygen in repairing blood-brain barrier in rats with ischemia-reperfusion injury.Methods A total of 54 Sprague-Dawley rats were randomly divided into sham operated group (n=12), cerebral ischemia-reperfusion injury (CIRI) model group (n=18), hyperbaric oxygen group (n=12) and inhibitor group (n=12). The CIRI model was made by a suture method in the model group, hyperbaric oxygen group and inhibitor group. The hyperbaric oxygen group and inhibitor group accepted hyperbaric oxygen, and the inhibitor group injected 3-methyladenine in lateral cerebral ventricle before treatment. They were stained with Evans blue and Evans blue content in the infarct area was detected 72 hours after CIRI. Double immunofluorescent staining was used to observe the expression of LC3 in vascular endothelial cells marked with CD31 in the model group, and LC3-II and Beclin-1 in infarcted cortical microvascular were examined by Western blotting in all the groups.Results Compared with the sham operation group, Evans blue content in the infarct area was significantly higher in the model group (P<0.01); compared with the model group, the content of Evans blue in the infarct area decreased significantly in hyperbaric oxygen group (P<0.01); compared with the hyperbaric oxygen group, the content of Evans blue in the infarct area was significantly higher in the inhibitor group (P < 0.05). There was obvious expression of LC3 in CD31+ cells. The expression levels of Beclin-1 and LC3-Ⅱ in the infarcted area were significantly higher in the model groupt than in the sham operation group (P<0.01); and it was significantly higher in the hyperbaric oxygen group than in the model group (P<0.05) and was lower in the inhibitor group than in the hyperbaric oxygen group and model group (P < 0.01).Conclusion Autophagy exists in vascular endothelial cells in the injured area of rats with CIRI. Hyperbaric oxygen can upregulate the expression of autophagy proteins LC3-Ⅱ and Beclin-1 in vascular endothelial cells in the infarcted area, to promote repairing blood-brain barrier.
ABSTRACT
Objective:To analyze characteristics of and distribution of pathogenic fungi in patients with tinea capitis in the First Affiliated Hospital of Xinjiang Medical University from 2010 to 2018.Methods:Clinical data were collected from 122 tinea capitis patients with positive fungal culture results in Department of Dermatology, First Affiliated Hospital of Xinjiang Medical University from 2010 to 2018, and retrospectively analyzed. Fungal culture was carried out, and lactophenol cotton blue staining was performed for morphological identification of the fungal isolates.Results:Of the 122 patients with tinea capitis, 112 (91.8%) were children, including 70 (62.5%) males and 42 (37.5%) females, and there were 58 (51.79%) preschool children and 37 (33.04%) school-age children; 9 (7.38%) were adults, including 7 females and 2 males; 66 (54.1%) were of Uygur nationality, 46 (37.7%) of Han nationality, 5 (4.1%) of Kazakh nationality, 3 (2.46%) of Hui nationality, 1 (0.82%) of Mongolian nationality, and 1 of unknown nationality. The annual number of cases of tinea capitis was more than 20 from 2011 to 2013, and gradually decreased year by year from 2014 (≤ 13 cases/year) . All the patients were infected with a single fungal strain, and a total of 122 strains were identified, including 46 (37.7%) strains of Microsporum ferrugineum, 44 (36.07%) strains of Microsporum canis, 10 (8.2%) strains of Trichophyton violaceum, 9 (7.38%) strains of Trichophyton schoenleini, 6 (4.91%) strains of Trichophyton tonsurans, 4 (3.28%) strains of Trichophyton mentagrophytes, 3 (2.46%) strains of Trichophyton verrucosum. Microsporum ferrugineum (anthropophilic species) mostly affected patients of Uygur nationality (34 cases, 73.91%) , and Microsporum canis (zoophilic species) mostly affected patients of Han nationality (26 cases, 59.09%) . Conclusion:In the Department of Dermatology, First Affiliated Hospital of Xinjiang Medical University from 2010 to 2018, tinea capitis commonly affected male children of Uygur nationality, and Microsporum ferrugineum and Microsporum canis were the dominant pathogenic species.
ABSTRACT
The paper is intended to analyze and evaluate the specific curative effect and safety of 2% liranaftate ointment in treating patients with tinea pedis and tinea cruris. 1,100 cases of patients with tinea pedis and tinea corporis and cruris were selected as research objects and were divided into two groups according to the random number table method. They were treated with different methods: 550 cases of patients were treated with 2% liranaftate ointment for external use in the observation group and the rest 550 cases of patients were treated with 1% bifonazole cream in the control group. The treatment time was two weeks for patients with tinea corporis and cruris and four weeks for those with tinea pedis respectively. Meanwhile, the one-month follow-up visit was conducted among the patients to compare the curative effects of two groups. After the medication, the curative effectiveness rate was 87.65% [482/550] in the observation group, while that was 84.91% [467/550] in the control group. After the average follow-up visits of [15.5 +/- 2.4], the curative effectiveness rate 96.55% [531/550] in the observation group, while that was 91.45% [503/550] in the control group. Two groups of patients recovered well with a low incidence of adverse reactions in the treatment, and the overall curative effect was good with the inter-group difference at P>0.05, so it was without statistical significance. The curative effect of 2% liranaftate ointment is safe and obvious in treating tinea pedis and tinea corporis and cruris, so it is valuable for clinical popularization and application

Multi-tragets are used for deep brain stimulation (DBS) to promote wakefulness, such as midbrain, thalamus, hypothalamus, etc. Lateral hypothalamic area may be one of the most potential tragets.
ABSTRACT
Objective To explore the effect of vagus nerve stimualtion on wake-promoting and the expression of 5-hydroxytryptamine (5-HT) 2A receptor in the prefrontal contex of coma rats with traumatic brain injury. Methods 72 Sprague-Dawley rats were randomly divid-ed into control group, sham-stimulated group, stimulated group and antagonist group with 18 rats in each group. Traumatic brain injury mod-el was established by a weight-drop head injury. The antagonist group was injected with SB334867, and both the antagonist group and the stimulated group received vagus nerve stimulation. Their behaviors were recorded. And immunohistochemistry technique was used to detect the expression of 5-HT2A receptor in the prefrontal cortex. Results 12 rats in the stimulated group, 9 in the antagonist group and 4 in the sham-stimulated woke up. The expression of 5-HT2A receptor from low to high was ranged as the control group, the antagonist group, the sham-stimulated group and the stimulated group (χ2=11.464, P=0.009). Conclusion Vagus nerve stimulation could raise consciousness in co-ma rats after traumatic brain injury, which may be related to up-regulating the expression of 5-HT2A receptor.
