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 preliminarily explore the effects and brain protective mechanism of intermittent hypoxia preconditioning ( IHP) on rats with seizures induced by lithium-pilocarpine ( Li-pilo) .Methods A total of 96 8-week old male Sprague Dawley rats ( clean grade ) were randomly divided into control group , seizure group and four IHP-seizure groups.The animal model of epilepsy was established by intraperitoneal injection of Li-pilo in the seizure group and four IHP-seizure groups (Li-pilo was injected at 1, 3, 7, or 14 days after a 5-day regimen of IHP).Subsequent seizure behavior , the latency period and percentage of generalized seizures were quantitatively evaluated for 240 min and the cognitive function was tested by Morris water maze task , and followed by the detection of hippocampus neuron apoptosis and related protein (BCL-2, Bax, and cleaved-caspase-3) by TUNEL labeling and Western blot, respectively.Results The induced seizure peaked on an average between 50-150 min after Li-pilo administration , scored using a modified Racine scale.The average scores of modified Racine scale in the IHP-3d seizure group was significantly lower than that in the other groups.The latency period and percentage of generalized seizures in the IHP-3d seizure group rats were significantly different from the parameters in the seizure group rats (P<0.05).IHP-3d seizure rats showed lower escape latency, neuronal apoptosis counts and higher percentage of time in the probe quadrant compare with the seizure group and the other three IHP-seizure groups ( P <0.05 ) .Compared with the control group , the parameters of water maze and apoptosis detection in the IHP-3d seizure group showed no significant changes (P>0.05).Conclusions The results indicate that IHP treatment may help to decrease the susceptibility to epilepsy by reducing abnormal apoptosis , and has a brain protective effect on the seizure rats .

Objective To prepare and characterize caspofungin acetate-loaded solid lipid nanoparticles using glycerol monostearate （CAS-SLNs）, and investigate the antifungal effect of potentiation on Candida albicans in vitro and in vivo. Methods A high performance liquid chromatography method was established for the determination of caspofungin acetate （CAS）. CAS-SLNs were prepared by the melt-emulsification method and characterized. The minimum inhibitory concentration （MIC） and the inhibitory effect on Candida albicans biofilm were determined. A systemic infection model of Candida albicans was established in mice, and the growth curve models for body weight and fungal load of kidneys of the animals were investigated after intravenous infection. Results The retention time of CAS was 6.8 min. The calibration curve showed good linearity, and the precision and stability met the requirements of the assay. Transmission electron microscopy revealed that CAS-SLNs were spherical, with a particle size of （135.97±1.73） nm. The Zeta potential was （19.33±0.37） mV, drug loading was （7.55±0.68）%, and encapsulation efficiency was （67.71±1.74）%. CAS-SLNs showed significant in vitro antifungal inhibition with a MIC of 9.78×10⁻⁴ g/ml, which was significantly better than CAS group and the physical mixture group of CAS and GMS, as well as the same biofilm inhibition was observed （P<0.001）. Pharmacodynamic studies demonstrated that CAS-SLNs maintained stable body weight gain compared to the control （P<0.01） and CAS groups in Candida albicans invasive infection model, and that CAS-SLNs significantly reduced renal fungal burden load relative to the CAS group （P<0.05）. In vivo study revealed that a stable body weight was maintained in CAS-SLNs group compared to the control group （P<0.01） in Candida albicans invasive infection model. CAS-SLNs also significantly reduced renal fungal load compared to the CAS group （P<0.05）. Conclusion CAS-SLNs significantly enhanced the antifungal effects of CAS in vitro and in vivo, which provided a valuable insight for the research of new formulation of CAS.

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.
