To explore the allergen sensitization status of patients with respiratory allergic diseases in Shanxi Province, and to provide a basis for the diagnosis, treatment and prevention of allergic diseases. It is a cross-sectional study, a total of 1 680 patients with allergic rhinitis and/or asthma diagnosed at the Department of Allergic Reaction of Shanxi Bethune Hospital from July 2021 to June 2023 who underwent allergen sIgE testing and/or skin prick test were retrospectively enrolled.There were 772 males and 908 females.The age range was 3 to 88 years. The median age was 35 years.There were 108 cases in the child group (≤12 years old), 102 cases in the adolescent group (13-17 years old), 819 cases in the youth group (18-40 years old), 498 cases in the middle-aged group (41-65 years old), and 153 cases in the elderly group (>65 years old). There were 333 cases in the allergic rhinitis group, 827 cases in the allergic asthma group, and 520 cases in the allergic rhinitis with asthma group. There were 1 254 urban patients and 426 rural patients.There were 253 cases in the northern Shanxi region, 1 195 cases in the central Shanxi region, and 232 cases in the southern Shanxi region. Statistical analyses were performed using the χ 2 test or Fisher's exact probability method to compare the differences in allergen sIgE positivity rates by sex, age, disease, living environment, and geography. The results showed that 1 027 patients (61.1%) were positive for at least one allergen sIgE, with Artemisia having the highest rate of positivity (603/1 680, 35.9%), followed by ragweed (302/1 680, 18.0%) and dust mite combinations (245/1 680, 14.6%). The number of individuals with single-allergen sIgE positivity was 357 (357/1 027, 34.8%), with the highest number of single-allergen sIgE positive results associated with Artemisia (114/357, 31.9%). The number of multiple-allergen sIgE positive results was 670 cases (670/1 027, 65.2%), with the highest number of patients having 2 allergen sIgE positive results (243/670, 36.3%). The overall positivity rate for allergen sIgE was significantly higher among males than among females (65.7% vs. 57.3%, χ2=12.405, P<0.001). Overall positivity for inhalant allergen sIgE was higher in the child and adolescent groups (88.0% vs. 88.2% vs. 59.8% vs. 40.2% vs. 19.0%, χ2=223.372, P<0.001), and food allergen sIgE positivity was highest in the child group (54.6% vs. 36.3% vs. 26.0% vs. 18.9% vs. 21.6%,χ2=66.383,P<0.001). The sIgE positivity rate of inhalant allergens was significantly higher in the allergic rhinitis group and the allergic rhinitis with asthma group than in the allergic asthma group, except for cockroaches and molds (P<0.05). The overall positive rate of allergen sIgE was significantly higher among urban patients than among rural patients (66.2% vs. 46.2%, χ2=53.230, P<0.001). The difference in the overall positive rate of allergen sIgE among patients from different regions was not statistically significant (56.1% vs. 62.0% vs. 62.1%, χ2=3.140, P=0.208). The sIgE positivity of dust mite combinations was significantly higher in the central Shanxi region and the southern Shanxi region than in the northern Shanxi region (15.5% vs. 18.1% vs. 7.1%,χ2=14.411, P=0.001). In conclusion, artemisia was the most important sensitizer for respiratory allergic diseases in Shanxi Province. The types of allergens and positivity rates were different for different sexes, ages, diseases, living environments, and regions. Therefore, patients with allergic diseases should be tested for allergens to help with the diagnosis, treatment and prevention of allergic diseases.

Tuberculosis (TB) caused by Mycobacterium tuberculosis (M. tuberculosis) infection remains a major public health problem of global concern, largely due to antibiotics resistance, persistence and immune evasion. Sphingolipid bioactive molecules are involved in several important pathophysiological processes. Sphingosine-1-phosphate is a key product of sphingolipid metabolism, and can play a role in two manners: autocrine and/or paracrine. Sphingosine-1-phosphate regulates T cells and a variety of antigen-presenting cells during M. tuberculosis infection, promotes antigen processing and expression in monocytes, is involved in the maturation of phagolysosome, regulates Ca2+ homeostasis, participates in the autophagy of macrophages, inhibits the survival and proliferation of M. tuberculosis within host cells, and effectively reduces the necrosis of the mouse lungs infected by M. tuberculosis. Injection of 20 nmol per mouse sphingosine-1-phosphate inhibited up to 47% of mycobacterial growth in the lung and spleen of mice infected by M. tuberculosis. In this paper, sphingosine-1-phosphate, its receptors and regulatory network were reviewed, and the specific mechanism of sphingosine-1-phosphate inhibiting the survival of M. tuberculosis-infected host cells was elaborated. This will provide novel insights into the new targets for tuberculosis prevention and treatment.

Objective: To study the possible mechanism of Tuoli Xiaodu Powder and disassembled prescriptions for the healing of wound in diabetic rats with skin ulcer. Methods: Totally 200 male SD rats were randomly divided into control group, model group, tuo disassembled prescription group, tou disassembled prescription group, and whole prescription group. The diabetes rat model was established using caudal vein injection of Streptozotocin (STZ) and the skin ulcer model was prepared by "back drilling" method. The rats in each group were given different prescriptions and corresponding physiological saline. The healing conditions of ulcer were observed on days 5, 8, 11, and 14 after treatment. The structural changes of granulation tissue were observed by HE staining. Expression of Tie-2, Ang-1, and Ang-2 in the granulation tissues of the wound were detected by Western blotting and immunohistochemistry. Results: The healing rate of each treatment group was higher than that of the DM group at all the time (P < 0.05); The healing rate of the tou group was higher than that of the tuo group and whole group on day 5 after treatment (P < 0.05); The healing rate of the whole group was higher than that of the tuo and tou group (P < 0.05). The expression of Ang-1 and Tie-2 was increased and that of Ang-2 was decreased in the whole group compared with the DM group (P < 0.05). Expression of Ang-2 in the tou group was significantly decreased on days 5 and 8 after treatment (P < 0.05). Expression of Ang-1 and Tie-2 in the tuo group was increased on days 11 and 14 after treatment (P < 0.05). Conclusion: The increased expression of Ang-1 and Tie-2 in the granulation tissue and the decreased expression of Ang-2 maybe the mechanism through which the Tuoli Xiaodu Powder promoting wound healing.

This study was aimed to discover the novel HLA recombination haplotypes and investigate the distribution of haplotypes in Chinese Han population. Based on the HLA-A, B, DRB1 typing results of 179 family members, 791 haplotypes were assigned by the mode of inheritance. The results showed that a total of 4 novel recombinant haplotypes in HLA-DRB1 locus region were observed in 4 families, which ratio of paternal to maternal chromosomes was 3:1. The recombination ratio between HLA-DRB1 and HLA-A or B loci was 0.92% (4/433). There were a total of 362 kinds of HLA-A, -B, -DRB1 haplotypes to be confirmed in Chinese Han partial population. A33-B58-DR17, A2-B46-DR9, A30-B13-DR7, A11-B13-DR15, A11-B75-DR12 and A2-B46-DR14 were the most common haplotypes that was consistent with the distribution of HLA alleles in unrelated donors. There were A1-B63-DR12, A29-B46-DR15, A1-B61-DR10, A34-B35-DR9, A29-B54-DR4, A23-B13-DR16 and A34-B62-DR15 haplotypes and so on, which were rare haplotypes not yet reported in Chinese. It is concluded that the HLA-A-B-DRB1 haplotypes would be confirmed by analysis of their family pedigree. The results obtained in this study are basic data for study of Chinese anthropology, organ transplantation and disease correlation analysis.
