Journal of Preventive Medicine 2023;35(1):83-86
Objective:
To evaluate the effectiveness of family interventions among children with allergic rhinitis receiving immunotherapy, so as to provide insights into improvements of allergic rhinitis treatment.
Methods:
A total of 80 children with allergic rhinitis admitted to The First People's Hospital of Linping District from July 2018 to July 2021 were enrolled and randomly assigned into the control and intervention groups, of 40 participants in each group, and all children underwent immunotherapy. Children in the control group received routine interventions, while participants in the intervention group were given family interventions for 3 months, including health education, psychological counseling, and periodical follow-up. Parental awareness of allergic rhinitis was investigated using self-designed questionnaires, and the compliance to immunotherapy was evaluated. The clinical symptoms were evaluated using the symptom scores and the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ), and the prognosis was evaluated using the Sino-Nasal Outcome Test-20 (SNOT-20).
Results:
There were no significant differences between the intervention and control groups in terms of gender, age, course of disease or disease severity (P>0.05). The scores for parental awareness of etiology [(9.56±0.25) vs. (7.45±0.85)], inducement factor [(8.84±0.62) vs. (6.76±1.36)], medication management [(9.56±0.25) vs. (7.97±0.85)] and daily life management of allergic rhinitis [(9.14±0.55) vs. (8.14±0.46)] were significantly higher in the intervention group than in the control group (P<0.05). The proportion of participants' compliance to immunotherapy was significantly higher in the intervention group than in the control group (92.50% vs. 75.00%, P<0.05). The scores for clinical symptoms [(3.12±0.94) vs. (3.96±1.23)], RQLQ score [(3.31±0.87) vs. (3.87±1.02)] and the SNOT-20 scores for nasal symptoms [(6.54±2.14) vs. (8.22±2.45)], sleep disorders [(4.11±0.58) vs. (5.24±1.03)], associated symptoms [(5.29±1.52) vs. (6.34±2.01)] and emotional consequences [(7.52±1.85) vs. (9.19±2.69)] were significantly lower in the intervention group than in the control group post-interventions (P<0.05).
Conclusion
Family interventions are effective to improve the compliance to immunotherapy, clinical symptoms, prognosis and quality of life among children with allergic rhinitis

Objective To observe the clinical effect of bevacizumab and temozolomide combined with concurrent radiotherapy for elderly patients with malignant brain glioma after the surgery . Methods A total of 55 patients in department of neurosurgery of Lanzhou Military Region General Hospital from January 2013 to December 2015 were enrolled. The patients were divided into control group and observation group. The 25 cases in the control group received radiotherapy and temozolomide. The 30 cases in the observation group received bevacizumab and temozolomide combined with concurrent radiotherapy. After treatment for 6 and 12 months, the clinical effects and adverse reactions of the two groups were compared byχ2 test, and the survival was compared by Log-rank test . Results Patients in the treatment group were followed up for 6 months after chemoradiotherapy, the response rate (RR) was 80 % (24/30), the disease control rate (DCR) was 97 % (29/30). The RR and DCR in the control group were 68 % (17/25) and 84 %(21/25). There were significant differences between the two groups (χ2 values were 3.742 and 8.000, both P<0.05). After 12 months of follow-up, the RR and DCR in the treatment group were 40 % (12/30) and 80 %(24/30), the control group were 16%(4/25) and 56%(14/25). There were significant differences between the two groups (χ2 values were 3.547 and 1.983, both P< 0.05). The adverse effect rates had no significant difference between the two groups (all P> 0.05). The 2-year survival rates in the treatment group and control group were 28.2 % and 11.0 %, the difference was statistically significant (χ 2 = 4.512, P = 0.034). Conclusions Temozolomide and bevacizumab combined with concurrent radiotherapy in treatment of malignant glioma is superior to temozolomide combined with radiotherapy, and bevacizumab is safe and has few side effects. It is a preferred treatment and is worthy of clinical promotion.

BACKGROUND:
Exploring the underlying mechanism of rituximab resistance is critical to improve the outcomes of patients with diffuse large B-cell lymphoma (DLBCL). Here, we tried to identify the effects of the axon guidance factor semaphorin-3F (SEMA3F) on rituximab resistance as well as its therapeutic value in DLBCL.
METHODS:
The effects of SEMA3F on the treatment response to rituximab were investigated by gain- or loss-of-function experiments. The role of the Hippo pathway in SEMA3F-mediated activity was explored. A xenograft mouse model generated by SEMA3F knockdown in cells was used to evaluate rituximab sensitivity and combined therapeutic effects. The prognostic value of SEMA3F and TAZ (WW domain-containing transcription regulator protein 1) was examined in the Gene Expression Omnibus (GEO) database and human DLBCL specimens.
RESULTS:
We found that loss of SEMA3F was related to a poor prognosis in patients who received rituximab-based immunochemotherapy instead of chemotherapy regimen. Knockdown of SEMA3F significantly repressed the expression of CD20 and reduced the proapoptotic activity and complement-dependent cytotoxicity (CDC) activity induced by rituximab. We further demonstrated that the Hippo pathway was involved in the SEMA3F-mediated regulation of CD20. Knockdown of SEMA3F expression induced the nuclear accumulation of TAZ and inhibited CD20 transcriptional levels via direct binding of the transcription factor TEAD2 and the CD20 promoter. Moreover, in patients with DLBCL, SEMA3F expression was negatively correlated with TAZ, and patients with SEMA3F low TAZ high had a limited benefit from a rituximab-based strategy. Specifically, treatment of DLBCL cells with rituximab and a YAP/TAZ inhibitor showed promising therapeutic effects in vitro and in vivo .
CONCLUSION
Our study thus defined a previously unknown mechanism of SEMA3F-mediated rituximab resistance through TAZ activation in DLBCL and identified potential therapeutic targets in patients.
