BACKGROUND: Asthma is a common chronic inflammatory airway disease and intermittent hypoxia is increasingly recognized as a factor that may impact disease progression. The present study investigated whether intermittent hypoxia (IH) could aggravate asthma by promoting hypoxia-inducible factor-1α (HIF-1α)/nucleotide-binding oligomerization domain (NOD)-like receptor pyrin domain-containing protein 3 (NLRP3)/interleukin (IL)-1β-dependent pyroptosis and the inflammatory response and further elucidated the underlying molecular mechanisms involved. METHODS: A total of 49 patients diagnosed with severe bronchial asthma and diagnosed by polysomnography were enrolled at Tongji Hospital, Tongji Medical College of Huazhong University of Science and Technology, between January 2022 and December 2022, and their general data and induced sputum were collected. BEAS-2B cells were treated with IL-13 and subjected to IH. An ovalbumin (OVA)-treated mouse model was also used to assess the effects of chronic intermittent hypoxia (CIH) on asthma. Pyroptosis, the inflammatory response, and related signalling pathways were assessed in vivo and in vitro . RESULTS: In this study, as the apnoea and hypopnea index (AHI) increased, the proportion of patients with uncontrolled asthma increased. The proportions of neutrophils and the levels of IL-6, IL-8, HIF-1α and NLRP3 in induced sputum were related to the AHI. NLRP3-mediated pyroptosis, which could be mediated by the HIF-1α signalling pathway, was activated in IL-13 plus IH-treated BEAS-2B cells and in the lungs of OVA/CIH mice. HIF-1α downregulation significantly reduced lung pyroptosis and ameliorated neutrophil inflammation by modulating the NLRP3/IL-1β pathway both in vitro and in vivo . Similarly, pretreatment with LW6, an inhibitor of HIF-1α, effectively blocked the generation of inflammatory cytokines in neutrophils. In addition, administration of the NLRP3 activator nigericin obviously increased lung neutrophil inflammation. CONCLUSIONS Obstructive sleep apnoea-hypopnea syndrome (OSAHS) is a risk factor for asthma exacerbation. IH aggravates neutrophil inflammation in asthma via NLRP3/IL-1β-dependent pyroptosis mediated by the HIF-1α signalling pathway, which should be considered a potential therapeutic target for the treatment of asthma with OSAHS.

It is believed that the endoscopic manifestations of interstitial cystitis/bladder pain syndrome （IC/BPS） such as extensive bleeding and Hunner's ulcers as well as its recurrent and prolonged condition are in line with the characteristics of sores and ulcers in traditional Chinese medicine （TCM）， and the treatment can be referred to TCM theory of sores and ulcers. The mechanism of IC/BPS is characterized by root deficiency and branch excess. The root cause is deficiency of the spleen and kidney qi， while the manifesting factors are dampness-heat and blood stasis. The treatment is based on the principles of promoting and supplementing， combining with resolving therapy， so that the symptoms could be relieved by promoting blood circulation and clearing heat， unblocking the collaterals and relieve pain. In clinical practice， modified Neituo Shengji Powder （内托生肌散） was commonly used to boost qi and invigorate blood， expel swollen sore and express toxin； combining with Sijunzi Decoction （四君子汤） or Suoquan Pill （缩泉丸） based on specific symptoms to strengthen the spleen and kidneys， thereby reinforcing healthy qi； according to concurrent symptoms like blood stasis， dampness heat， prescription with Sanleng （Cyperus rotundus）， Ezhu （Curcuma aromatica Salisb） to invigorate blood and dissolve stasis， or Yiyiren （Coix lacryma-jobi）， Zexie （Alisma plantago-aquatica） to clear heat and drain dampness.

Background: Overactive bladder (OAB) is a prevalent condition that substantially degrades patient quality of life. Acupuncture is recognized as an effective therapeutic approach for various urological diseases. However, there is limited evidence validating the effectiveness and safety of acupuncture for OABs. Objective: To assess the therapeutic efficacy of acupuncture for OAB and to investigate the potential mechanisms by analyzing its effects on relevant urinary biomarkers. Methods: This is a randomized, participants and outcome assessors blinded, sham acupuncture controlled trial. A total of 110 patients with OABs will be randomly divided in a 1:1 ratio between the acupuncture and sham acupuncture groups. Participants in the acupuncture group will undergo 30-min authentic acupuncture, while their counterparts in the sham acupuncture group will undergo sham acupuncture needling non-acupoints superficially three times weekly for a duration of 8 weeks. The two co-primary outcomes will be the change in the mean number of micturitions per 24 h from baseline to the end of the 8-week treatment and 20-week follow-up. The secondary outcomes will encompass the change in Overactive Bladder Symptom Score, Overactive Bladder Questionnaire Short Form, and average 24 h values of urgency, daytime micturition, nocturia, and mean volume voided per micturition from baseline to weeks 8 and 20. Urinary nerve growth factor, brain-derived neurotrophic factor, and monocyte chemoattractant protein-1 levels will be measured at baseline and week 8. Adverse events will also be documented. Discussion The results of this trial will provide evidence for the effectiveness and safety of acupuncture in the management of OAB.

【Objective】 To analyze the commonality and characteristics between voluntary blood donors and hematopoietic stem cell donors in this region, and explore the potential for integration and development between China Marrow Donors Program (CMDP) and voluntary blood donors, especially platelet donor databases, so as to improve recruitment success rate and inventory rate. 【Methods】 The database modeling and comparison methods were used to screen and stratify the matching and integration degree between the voluntary blood donors in recent 10 years and the marrow donors in the Shaanxi Branch of CMDP. The frequencies of HLA-A,-B alleles, HPA alleles and haplotypes were calculated with Arlequin 3. 5. 2. 2 software, and the matching probability of different platelet donor reserve pools was conducted according to the phenotypic frequencies. 【Results】 Among the voluntary donors with known HLA genotypes in this region, according to their blood donation behavior,the active blood donors excavated were divided into the first, second, third and fourth echelons of platelet donor reserve pools, with 696, 2 752, 9 092 and 12 028 donors, respectively. The first echelon had the highest proportion of 10-50 times of platelet donations and 10-20 times of whole blood donations, with 13.65% and 26.01%, respectively. The second echelon had 10-20 times of whole blood donations and 10-50 times of platelet donations, accounted for 15.04% and 1.38%, respectively, which were significantly different from other echelons' blood donation characteristics (P<0.05). With a database size of the existing platelet donor bank adding the first and second echelons (n=4 955), there was a 69.02% probability of matching at least one donor with matching HLA-A-B phenotype. When considering the matching ABO and HPA phenotypes, the probability of finding at least one donor with fully matching HLA, HPA and ABO isotype (type B as an example) was 48. 73%. 【Conclusion】 The three groups of whole blood donation, apheresis platelet donation and marrow donation in Xi'an area have a large cross-distribution. Compared with expanding the storage capacity from scratch, the active blood donors in CMDP database are the largest back-up force of platelet donors. While expanding the effective storage capacity, it can minimize the cost of building platelet donor bank and the demand for resources.

Objective To investigate the efficacy of kinesio taping(KT)in the treatment of pain,function,range of motion and muscle strength in patients with knee articular osteoarthritis(OA).Method Forty patients with knee articular OA diagnosed in our hospital from January 2021 to January 2023 were selected.We randomly divided them into two groups,each with 20 cases.The observation group received KT therapy,while the control group received sham bandage therapy.Visual Analogue Scale/Score(VAS)was used to assess the degree of activity and nocturnal pain,KOOS score was used to assess the functional status of patients,digital goniometer was used to measure the range of activity and hand-held force meter was used to assess muscle strength.The evaluation time includes before treatment and on the 12th day of treatment.Result Compared with before treatment,the pain,function,range of motion,and muscle strength of patients in the control group and KT group were significantly improved after treatment.And compared with the control group,the KT group also significantly improved the above indicators after treatment.Conclusion KT therapy has significant efficacy in relieving short-term pain and improving functional limitations in knee osteoarthritis.

Objective:To investigate the clinical characteristics and gene sequencing results of NDM, so as to provide evidence for clinical diagnosis and treatment .Methods:Clinical data of 1 child diagnosed with NDM in Hebei People's Hospital in January 2021 were retrospectively analyzed, and DNA gene sequencing was performed in the peripheral blood of the child, and relevant literatures were reviewed.Results:The child was born with a weight of 2.2kg. On the second day after birth, blood glucose significantly increased and insulin and C-peptide levels decreased. After 14 days of insulin treatment, hyperglycemia was still present, which was consistent with the diagnosis of NDM. Genetic testing indicated that there were missense mutations of newborn compound heterozygote in ABCC8 gene: c. 752G > A (p.G251E), c. 772A > G (p.R258G). The mutation of c. 772A > G in ABCC8 gene had not been reported before, and sulfonylureas were effective for the treatment of the child.Conclusion:NDM is a rare monogenic genetic disease with a lack of specificity in clinical manifestations. For children diagnosed or suspected of NDM, genetic testing should be actively carried out, which is of great significance for clinical diagnosis, treatment and prognosis.
