Objective To study the distribution of Sporothrix in natural environment in Jilin province. Methods Specimens of decayed reed, corn stalks, rotten wood and soil from areas of high incidence rate of sporotricosis (Tongyu county and Nongan county) and low incidence rate (Tumen county) were randomly collected, cultured and subcultured for sporothrix, and the isolates were identified. Results 21 strains of Sporothrix schenckii were isolated and identified. It is the first report that Sporothrix is isolated from corn stalks, rotten wood and soil in our country and is the first report in the world that Sporothrix is isolated from corn stalks. Conclusion The results of study show that there are parasitic Sporothrix schenckii in the reed, corn stalks, rotten wood and soil in the region with high incidence rate of sporotrichosis, and parasitic Sporothrix schenckii in the reed and rotten wood have also been found in the region with low incidence rate. The finding of biological distribution of Sporothrix in the province is of great significance for the prevention and treatment of sporothrichosis.

Objective To identify the effect of long hazardous drinking on cardiovascular function and cardiovascu?lar abnormalities among alcohol dependent patients. Methods A follow-up survey was conducted, 72 potential patients who were diagnosed as having alcohol dependence were recruited into case group and 75 staff who underwent routine health examination were subjected into control group. Furthermore, 52 patients were subdivided into long hazardous drinking group (GroupⅠ) according to the classification of alcohol consumption published by WHO. The rest patients in the case group were considered as not long hazardous drinkers (GroupⅡ). The blood lipid data, echocardiography and ca?rotid artery brachial artery ultrasonography measurement data were compared between the three groups. The high risk fac?tors for cardiovascular abnormalities among alcohol dependence patients were analyzed. And one year after discharge, telephone follow-up method was used to obtain the incidence of cardiovascular accident among patients. Results The dis?tribution of blood lipid data among GroupⅠ, Ⅱ and control group were not significantly different (P>0.05). The LVEF score in GroupⅠwas significantly lower than that in control group (P<0.01). The LAAEF score in GroupⅠwas signifi? cantly higher than that in control group and that in the GroupⅡ(P<0.05). While the FDM and IMT score in the GroupⅠwas significantly lower than that in control group (P<0.01). In the case group, the duration of drinking alcohol was neg?atively associated with LAPEF (r=-0.246, P=0.014) and LAAEF (r=0.239, P=0.016). The average daily alcohol consump?tion was positively associated with LVEF (r=0.256, P=0.010), while negatively correlated with FMD (r=-0.256,P=0.010). Multivariate logistic regression analysis showed that long hazardous drinking was an independent risk factor for cardiovas?cular abnormalities (OR=1.334, 95%CI: 1.060~1.678). Conclusion Long hazardous drinking can reduce left ventricular diastolic and vascular endothelial function. It is an independent risk factor for cardiovascular abnormalities in alcohol de?pendent patient.

0.05).No serious adverse events were reported in these two groups.The incidences of adverse event of mizolastine and loratadine were28.6%and25.5%respectively,there were no statistically significant difference between two groups(? 2 =0.25,P=0.62).Conclusions The efficacy of mizolastine and loratadine is similar in the treatment of CIU,but mizolastine is quicker in action than loratadine.The incidences of adverse events are not different in the two groups.

Sporotrichosis has been classified as "neglected tropical diseases" by the World Health Organization. In recent years, researches on sporotrichosis have gradually increased. This review summarizes recent progress in sporotrichosis in terms of pathogens, epidemiology, diagnosis, treatment and vaccines.

Objective To quantitatively compare the γ-H2AX foci formation between DNA-PKcs+/+and DNA-PKcs-/-mouse embryonic fibroblast(MEF)cells,and to investigate the dynamic changes in DNA double-strand breaks(DSBs)in human nasopharyngeal carcinoma SUNE-1 cells exposed to X-ray radiation. Methods The expression of DNA-PKcs was determined by Western blot. The γ-H2AX foci formation induced by 5 Gy X-ray radiation was detected by cell immunofluorescence. The ImageJ software was used to quantitatively analyze the γ-H2AX foci formation. Results The expression of DNA-PKcs was silenced in DNA-PKcs-/-MEF cells and normal in DNA-PKcs+/+MEF cells. According to the dynamic analyses of the numbers of γ-H2AX foci/cell and γ-H2AX foci/mm2, a similar tendency was observed in DSB formation in DNA-PKcs+/+MEF cells, DNA-PKcs-/-MEF cells,and SUNE-1 cells exposed to X-ray radiation. A large number of γ-H2AX foci formed at 0.5-1.0 h after radiation. DSBs were repaired at 6 h after radiation in DNA-PKcs+/+MEF cells and 24 h after radiation in DNA-PKcs-/-MEF cells and SUNE-1 cells. The peak values of γ-H2AX foci/cell and γ-H2AX foci/mm2were observed at 1.0 and 0.5 h after radiation, respectively. Compared with DNA-PKcs+/+MEF cells, DNA-PKcs-/-MEF cells had different numbers of γ-H2AX foci/cell at 0.5, 1.0, 3.0, 6.0, and 12.0 h after radiation, as well as different numbers of γ-H2AX foci/mm2at 3.0, 6.0, and 12.0 h after radiation. Conclusions Quantitative measurement of the number of γ-H2AX foci/cell or γ-H2AX foci/mm2by cell immunofluorescence provides new insights into the quantitative and dynamic study of DSB damage and repair.

BACKGROUND: Atopic dermatitis (AD) affects approximately 10% of adults worldwide. CM310 is a humanized monoclonal antibody targeting interleukin-4 receptor alpha that blocks interleukin-4 and interleukin-13 signaling. This trial aimed to evaluate the efficacy and safety of CM310 in Chinese adults with moderate-to-severe AD. METHODS: This multicenter, randomized, double-blind, placebo-controlled, phase 2b trial was conducted in 21 medical institutions in China from February to November 2021. Totally 120 eligible patients were enrolled and randomized (1:1:1) to receive subcutaneous injections of 300 mg CM310, 150 mg CM310, or placebo every 2 weeks for 16 weeks, followed by an 8-week follow-up period. The primary endpoint was the proportion of patients achieving ≥75% improvement in the Eczema Area and Severity Index (EASI-75) score from baseline at week 16. Safety and pharmacodynamics were also studied. RESULTS: At week 16, the proportion of EASI-75 responders from baseline was significantly higher in the CM310 groups (70% [28/40] for high-dose and 65% [26/40] for low-dose) than that in the placebo group (20%[8/40]). The differences in EASI-75 response rate were 50% (high vs . placebo, 95% CI 31%-69%) and 45% (low vs . placebo, 95% CI 26%-64%), with both P values <0.0001. CM310 at both doses also significantly improved the EASI score, Investigator's Global Assessment score, daily peak pruritus Numerical Rating Scale, AD-affected body surface area, and Dermatology Life Quality Index compared with placebo. CM310 treatment reduced levels of thymus and activation-regulated chemokine, total immunoglobulin E, lactate dehydrogenase, and blood eosinophils. The incidence of treatment-emergent adverse events (TEAEs) was similar among all three groups, with the most common TEAEs reported being upper respiratory tract infection, atopic dermatitis, hyperlipidemia, and hyperuricemia. No severe adverse events were deemed to be attributed to CM310. CONCLUSION CM310 at 150 mg and 300 mg every 2 weeks demonstrated significant efficacy and was well-tolerated in adults with moderate-to-severe AD.
