Allergen specific immunotherapy（AIT）, as an effective treatment for allergic rhinitis, asthma, and other allergic diseases, has received widespread attention in the field of health economic evaluation in recent years. This article reviews the current status and progress of economic research on AIT, mainly discussing the socioeconomic burden of allergic rhinitis, the results of health economic studies from different countries, and the primary methods used in health economic research on allergic rhinitis. Existing studies indicate that, although AIT involves high initial costs, it offers significant long-term economic benefits by reducing healthcare resource utilization, improving patient quality of life, and decreasing medication dependence. Moreover, reducing initial costs, applying standardized assessment tools, and conducting cross-national comparative analyses have become key directions for future research. Overall, AIT demonstrates strong potential in terms of long-term health benefits and cost savings, providing solid economic evidence for the management of allergic diseases.

Objective To investigate the situation of HIV infection and epidemiological characteristics among voluntary blood donors and pre-transfusion patients in Yuxi prefecture between 2010 and 2021.Methods Da-te collected with the HIV/AIDS Case Reporting Cards and original record of blood station,HIV antibody positive rate,the demographic characteristics,and epidemiological data of blood donors and pre-transfusion patients,were analyzed accordingly,the related date were statistically analyzed.Results The HIV antibody positive ratio were 5.56? and 2.01? among pre-transfusion patients and voluntary blood donors(P<0.001),showing an downward trend year after year.The HIV-positive detection rate among blood donors aged<25 years was significantly higher at 3.72‰ compared to 1.60‰ for those aged≥25 years(P=0.003).Among HIV-positive blood recipients,the proportion of individuals aged 15-24 years(34.62%)was markedly higher than that among blood donors(1.96%),whereas no donors were aged≥50 years compared to 23.53%of recipients(P<0.001).Farmers showed a significantly higher HIV detection rate(3.18‰)than students(2.66‰)and other occupations(1.60‰)(P=0.041).Similarly,individuals with high school education or below showed a higher detection rate(2.52‰)than those with high school education or above(1.45‰)(P=0.045).Among HIV-positive cases,blood donors had a higher proportion of HIV-infected individuals(84.62%)versus AIDS cases(15.38%),whereas the recipients showed the opposite trend:41.18%HIV-infected versus 58.82%AIDS cases(P<0.001).Conclusion In recent years,the HIV positive detection rate in Yuxi area has shown a downward trend,but the occurrence of HIV in Yuxi area is characterized by youthfulness and low education.Among them,HIV infected individuals through same-sex contact account for an important reason for HIV infection.

Objective:To explore the effects of parathyroid hormone(PTH)on the osteogenic differentiation of osteoblasts by reg-ulating macrophage polarization in inflammatory microenvironment.Methods:Macrophages were pretreated with lipopolysaccharide(LPS)for 2 h to establish an inflammatory microenvironment model,and then treated with PTH for 24 h.Macrophages and osteo-blasts were co-cultured in Transwell cells.Alkaline phosphatase staining,alizarin red staining,RT-qPCR and Western blot were applied to detect osteogenic differentiation.The expression of SOCS1/JAK2/STAT3 protein in macrophages was detected by West-ern blot.The change of STAT3 expression was detected after adding AG490.The expression of miR-155-5p,SOCS1,IL-1β,IL-6 and i-NOS was detected by ELISA and RT-qPCR.Results:LPS induced M1-type polarization of macrophages and inhibited the osteogenic differentiation of osteoblasts.PTH inhibited the polarization of M1-type macrophages and promoted the osteogenic differ-entiation of osteoblasts in inflammatory microenvironment(P＜0.05).PTH down-regulated the expression of miR-155-5p,IL-1β,IL-6,i-NOS,p-JAK2/JAK2 and p-STAT3/STAT3 in macrophages under inflammatory microenvironment(P＜0.05),and up-reg-ulated SOCS1(P＜0.05).AG490 further inhibited p-STAT3/STAT3 expression.Conclusion:PTH inhibits the polarization of M1-type macrophages and promotes osteogenic differentiation of osteoblasts by down-regulating miR-155-5p and then targeting SOCS1/JAK2/STAT3 signaling pathway in inflammatory microenvironment.

To analyze all-cause mortality among hepatitis C cases aged ≥18 years in Yuxi City from 2005 to 2023 and explore the interactions of factors influencing survival time. Baseline and follow-up data for hepatitis C cases reported during this period were extracted from the Chinese National Notifiable Disease Reporting System. Survival time and related factors were assessed using the Cox proportional hazards model. Kaplan-Meier cumulative mortality risk curves were generated for treated and untreated hepatitis C cases, and interactions among subgroups of various influencing factors were examined. A total of 5 110 hepatitis C cases aged ≥18 years were reported from 2005 to 2023, encompassing 35 349.25 person-years of observation with the follow-up time duration M ( Q1, Q3) was 6.17 (2.33, 11.08) person-years. There were 763 all-cause deaths, corresponding to a mortality density of 2.16 per 100 person-years. Survival analysis showed a statistically significant difference in cumulative mortality between the treated and untreated groups (Log-rank χ2=122.033, P<0.001), with a lower risk of death observed among treated patients. Additive model analysis showed that there was a synergistic interaction between treatment status and age group, with relative excess of interaction, attributable proportions of interaction, and synergy index of 6.16 (95 %CI: 2.70-9.61), 1.83 (95 %CI: 1.46-2.30), and 0.42 (95 %CI: 0.31-0.53), respectively; and between treatment status and gender. There was a synergistic interaction between treatment status and sex, with relative excess of interaction, attributable proportions of interaction, and synergy index of 2.63 (95 %CI: 1.14-4.13), 1.56 (95 %CI: 1.19-2.06), and 0.32 (95 %CI: 0.17-0.46), respectively. The cause of death composition were 38.53% (249 cases) attributed to hepatitis C-related causes.The leading non-hepatitis C-related causes of death were cardiovascular and cerebrovascular diseases, pulmonary diseases, malignancies, drug overdose, and injuries. In conclusion, hepatitis C cases ≥18 years of age in Yuxi City had a lower cumulative mortality rate when treated than when untreated. Treatment status interacted with age and gender on patient survival, respectively. Changes in patients with concomitant cardiovascular diseases, pulmonary diseases and malignancies should be focused.

Objective In this study,we tested different disinfectants and different action times to establish an efficient protocol for zebrafish embryo disinfection,which may in turn improve the management of zebrafish facilities.Methods We tested three reagents that can be used for embryo disinfection and are readily available in the domestic market:reagent-grade povidone-iodine,sodium hypochlorite,and chlorine dioxide.We evaluated the toxic effects of the reagents at three concentrations and two action times on zebrafish embryos at three stages,in term of survival,dechorioning,and malformation rates.The effects of the three disinfectants were also compared in terms of the amounts of embryos with surface bacteria after disinfection.Results Chlorine-containing disinfectants,i.e.sodium hypochlorite and chlorine dioxide,were better able to kill bacteria on the embryo surface,while povidone-iodine was not quite effective.Survival,dechorioning,and malformation rates were similar in embryos treated with 30 ppm sodium hypochlorite or chlorine dioxide to those in control embryos.Treatment with chlorine-containing disinfectants for 10 min were more effective in sterilizing than for 5 min.Conclusions The result of this study suggest treating 6～30 hpf embryos with 30 ppm sodium hypochlorite for 10 min as an operational method.
