Objective:To investigate associations of serum β 2-microglobulin (β 2M) with baseline stroke severity and outcome at 3 months after onset in patients with acute ischemic stroke (AIS). Methods:Patients with first-ever AIS admitted to the Department of Neurology, the Affiliated Municipal Hospital of Xuzhou Medical University from January 2018 to May 2022 were included retrospectively. The severity of stroke was evaluated according to the National Institute of Health Stroke Scale score at admission. ≤8 was defined as mild stroke, and >8 was defined as moderate to severe stroke. At 3 months after onset, the modified Rankin Scale was used to evaluate the clinical outcome, ≤2 points was defined as good outcome and >2 points was defined as poor outcome. Multivariate logistic regression analysis was used to determine associations of β 2M with the severity and outcome of stroke. Results:A total of 463 patients with AIS were enrolled, including 263 males (56.68%), aged 62.89±11.77 years. There were 319 patients (68.89%) in the mild stroke group and 144 (31.10%) in the moderate to severe stroke group; 304 patients (65.66%) in the good outcome group and 159 (34.34%) in the poor outcome group. Univariate analysis showed that the β 2M in the moderate to severe stroke group and the poor outcome group were significantly higher than those in the mild stroke group and the good outcome group, respectively (all P<0.05). Multivariate logistic regression analysis showed that β 2M was an independent influencing factor for stroke severity (odds ratio 2.476, 95% confidence interval 1.621-3.783; P<0.001) and poor outcome (odds ratio 5.179, 95% confidence interval 2.941-11.121; P<0.001) in patients with AIS. Conclusion:There is a significant independent correlation between high serum β 2M and the severity and poor outcome of stroke in patients with AIS.

OBJECTIVE: To analyze the main allergens in children with allergic rhinitis and provide scientific basis for prevention and treatment in Zhengzhou district. METHOD: Twenty standardization allergens were used to perform skin prick test in 412 children with AR, and the results were statistically analyzed. RESULT: Three hundred and twenty-nine of 412 cases (79.85%) showed positive reaction. The positive rate of dermatophagoides farina (87.54%) was the highest in inhaled allergens, followed by dermatophagoides pteronyssinus (86.32%), cat hair (62.31%), fungus I (47.72%) and dog hair (43.16%). The positive rate of shrimp (13.68%) was the highest in ingestive allergens, then egg (5.17%), carp (4.56%), meat I (3. 04%) and milk (3.04%). CONCLUSION Dust mites, cat hair, fungus,dog hair were the most common allergens in children in Zhengzhou district. Improving living environment of children with AR and avoiding contacting with allergens were pretty important.

OBJECTIVE: To evaluate the effect of two surgical methods on treatment of allergic rhiniti complicated with nasal septum deviation. METHOD: Eighty-seven cases of allergic rhiniti complicated with nasal septum deviation were divided into 2 groups according to the degree of mucosal hypertrophy and hyperplasia of bone in inferior turbinate. They were treated by resection of nasal septum deviation combined with temperature-controlled radio-frequency, or combined with partial submucoperiosteous resection of inferior turbinate bone. The Lanzhou standard (2004) and nasal airway resistance were used to evaluate the efficacy. RESULT: After one year follow-up time, the nasal resistance was significantly decreased and the effective rates were greater than 88% in each group. CONCLUSION Both of the two surgical methods can significantly depress the nasal resistance and improve the allergic symptoms, which shows good effect.
