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.

Objective： To systematically evaluate the clinical efficacy and safety of Tonifying kidney and activating blood therapy for the treatment of diabetic mellitus erectile dysfunction. Methods： China National Knowledge Infrastructure(CNKI), Wanfang Data, VIP, Chinese Biomedical Database(CBM), PubMed, Cochrane Library, Embase and Web of Science were searched from inception until October 20th of 2024，for randomized controlled trials of Tonifying kidney and activating blood therapy for the treatment of diabetic erectile dysfunction. Literature screening, quality evaluation, and data extraction were carried out in accordance with relevant standards. The software of RevMan5.4 was used for the analysis of publication bias. And meta-analysis was conducted to assess the impact of this therapy on IIEF-5, total effective rate, adverse reactions. The evidence levels according to the analysis results were evaluated. Results: Totally 19 RCTs were included, involving 1 612 patients. The result of meta-analysis indicated that Tonifying kidney and activating blood therapy had advantages on the improvement of IIEF-5 scores (MD=3.59，95%CI［2.14，5.03］，P<0.01)，total effective rate (OR=4.30，95%CI［3.29，5.32］，P<0.000 01）. However, there was no statistically significant difference in the incidence of adverse reactions(OR=0.98，95%CI［0.48，2.01］，P=0.96) between the two groups. Conclusions： Tonifying kidney and activating blood therapy can improve the clinical efficacy and IIEF-5 score for the patients with diabetic erectile dysfunction. But considering the limited quantity of included studies, more high-quality studies still be needed to validate the therapeutic effect.

Background: Condyloma acuminatum (CA) is a common sexually transmitted disease caused by human papillomavirus (HPV). In recent years, research on anal CA has primarily focused on treatment rather than underlying mechanisms. The mechanism of HPV persistence and recurrence in CA require further exploration. It needs multiple researches in mechanisms to focalize treatment targets. Objective: To investigate the relationship between intestinal mucosal immunity and the relapse of anal CA and persistent infection. Methods: Levels of interferon gamma (IFN-γ) and secretory immunoglobulin A (sIgA) were measured using enzyme-linked immunosorbnent assay in anal mucosal cells obtained from patients treated at Tianjin Union Medical Center from September 2022 to December 2024. All the participants signed Informed Consent and the whole plan was approved by Institutional Review Board in Tianjin Union Medical Center (No. B155). Results: The levels of IFN-γ and sIgA significantly decreased after infection, and persistent infection exhibited even lower levels. These two factors increased following treatment, reaching peak concentrations at 4 weeks before decreasing again. Conclusion These findings demonstrate a significant association between persistent anal CA infection and dysregulation of intestinal mucosal immunity.

Objective:To explore the mechanism of hypertension inducing erectile dysfunction(ED)using transcriptomics and network pharmacology.Methods:We randomly divided 12 male rats with spontaneous hypertension(SHT)into an L-arginine(LA)group(n=6)and an SHT model control(MC)group(n=6),took another 6 Wistar Kyoto male rats as normal controls(NC),and treated the animals in the LA group by intraperitoneal injection of LA at 400 mg/kg and those in the latter two groups with physio-logical saline,once a day,all for 7 days.Then we observed the blood pressure and penile erection of the rats,and determined the ex-pressions of the cGMP/PKG signaling pathway-related proteins and mRNAs in different groups using ELISA,Western blot and RT-qPCR.Results:Transcriptomics combined with network pharmacology showed that the cGMP/PKG signaling pathway played a key role in hypertension-induced ED.In vivo animal experiments revealed a significantly lower frequency of penile erections in the MC than in the NC group(1.33±0.52 vs 2.67±0.51,P＜0.05).The protein expressions of eNOS,PKG and sGC were markedly de-creased in the model controls compared with those the normal controls(P＜0.05),but remarkably upregulated in the LA group com-pared with those in the MC group(P＜0.05).Conclusion:Hypertension decreases the expressions of eNOS,NO,sGC,cGMP and PKG proteins and the level of testosterone by inhibiting the cGMP/PKG signaling pathway,which consequently suppresses the relaxa-tion of the penile vascular smooth muscle and reduces erectile function.

OBJECTIVE: To explore clinical effect of high-intensity laser therapy(HILT) combined with targeted hand function training on pain and lateral pinch force in grade 1-2 thumb carpometacarpal(CMC) osteoarthritis(OA). METHODS: From April 2020 and April 2022, 42 female patients with thumb CMC OA grade 1 to 2, aged from 58 to 80 years old with an everage of (68.90±7.58) years old were divided into observation group of 21 patients who received HILT and targeted hand function training for 4 weeks, and 21 patients in control group who received ultrashort wave therapy combined with using of an orthosis for 4 weeks. Visual analogue scale(VAS) was applied to evaluate degree of pain, function of finger was evaluated by dynamometer to measure lateral pinch force at baseline, immediately following intervention at 4 and 12 weeks following intervention. RESULTS: VAS and lateral pinch force at immediately and 12 weeks after intervention betwwen two groups were better than that of before intervention(P<0.05). Compared with control group, the degree of pain in observation group improved more(immediately after intervention t=3.37, P<0.05, 12 weeks after intervention t=9.05, P<0.05), lateral pinch force higher than that of control group (immediately after intervention t=-2.55, P<0.05, 12 weeks after intervention t=9.51, P<0.05). CONCLUSION High-intensity laser therapy combined with targeted hand function training is more effective than traditional methods in improving pain and lateral pinch force in grade 1-2 thumb carpometacarpal osteoarthritis.

Development of extramural health care for chronic wounds is still in its infancy in China, and thus it is urgent and vital to establish a correct concept and practicable principles. The authors reviewed recent domestic and international literature and summarized the following treatment procedures and principles for extramural health care of chronic wounds. (1) The patient needs to do self-assessment of the wound by using available simple methods; (2) The patient consults with professional physicians or nurses on wound care to define the severity and etiology of the non-healing wound; (3) Professionals evaluate the existing treatment strategies; (4) Etiological treatments are given by professionals; (5) Patients buy needed dressings via the more convenient ways from pharmacies, e-commerce platform or others; (6) Professionals provide a standardized and reasonable therapeutic plan based on the patient's wound conditions; (7) Both professionals and the patient pay attention to complications to prevent adverse outcomes; (8) Professionals strengthen the public education on wound care and integrated rehabilitation. This review expected to provide new perspectives on the therapeutic strategies for chronic wounds in an extramural setting.

Objective: To evaluate diet quality and related problems among children and adolescents in Yunnan Province, in order to provide a theoretical basis for the formulation of targeted dietary interventions for children and adolescents in this region. Methods: Using a stratified random sampling method, 1 078 primary and secondary school students from six prefecture level cities in Yunnan Province were selected from August to November 2022. Dietary quality was evaluated by applying the China Children s Dietary Index (CCDI-2016) on the basis of a 3 d 24 h dietary survey. Results: The total dietary index score of children and adolescents in Yunnan Province was 62.63(54.57,71.19). The overall recommended intakes were largely achieved by consumption of cereals, eggs and sugary drinks, with dietary index scores of 9.91(8.24,10.00), 5.58(0,8.58) and 9.20(7.38,10.00), respectively; there were inadequate intakes of vegetables, legumes, water, vitamin A and dietary fiber, with scores of 5.63(4.09,7.59), 3.48 (0,9.70), 4.23(2.67,5.50), 2.33(1.56,3.53), 3.19(1.63,5.67), respectively; intake of fruits, dairy and aquatic products were severely deficient, with scores of 0(0,1.74), 0(0,2.37), 0(0,9.85), respectively; excessive intake of meat was found, with a dietary index score of 0(0,2.46). The stratified analysis showed that children and adolescents aged 11-13 years had the highest total dietary scores[65.35(54.29,72.03)], followed by those aged 7-10 years[63.46(56.19,72.63)], while the 14-17 year old age group had the lowest scores[59.07(51.15,68.30), H=32.23, P <0.01]. Girls had higher total dietary scores than that of boys[64.20(56.12,72.56), 59.32(52.60,69.72), Z=-5.16, P <0.01], while urban children and adolescents had higher total dietary scores than rural children and adolescents[65.30(54.84,73.62), 62.17(54.31,70.70), Z=-2.11, P <0.05]. Furthermore, higher total dietary index scores were observed among children and adolescents whose parents had a higher educational level( H=27.68, 22.58, P <0.01). The comparison of ethnic groups revealed that the Wa children and adolescents had the highest total dietary index scores, while the Hani children had the lowest( H=27.51, P <0.01). Conclusion The overall dietary quality of children and adolescents in Yunnan Province is not high, the imbalance of dietary nutrition is prominent, and the dietary structure needs to be adjusted and optimized. Intervention programs should focus on the problem of insufficient intake of fruits and vegetables, milk and legumes, aquatic products and excessive intake of poultry meat among children and adolescents.

Objective: To explore a method for digitally designing and fabricating a sequential tooth-sectioning guide that can assist in the extraction of mandibular horizontal impacted third molars, preliminarily evaluate its feasibility and provide a reference for clinical application. Methods: Twenty patients with mandibular low level impacted third molars who visited the Department of General Dentistry, Peking University School and Hospital of Stomatology from March 2021 to January 2022 were selected. Cone-beam CT showed direct contact between the roots and mandibular canal, and full range impressions of the patients' intraoral teeth were taken and optical scans of the dental model were performed. The patients' cone-beam CT data and optical scan data were reconstructed in three dimensions, anatomical structure extraction, registration fusion, and the design of the structure of the guide (including crown-sectioning guide and root-sectioning guide) by Mimics 24.0, Geomagic Wrap 2021, and Magics 21.0 software, and then the titanium guide was three dimension printed, and the guide was tried on the dental model. After confirmation, the guide was used to assist the dentist in the operation. We observed whether the guide was in place, the number of tooth splitting, the matching of tooth splitting with the preoperative design, the operation time, and whether there were any complications. Results: In this study, 20 sectioning guides were successfully printed, all of them were well fitted in the patients' mouth, the average number of section was 3.4 times, the tooth parts was better matched with the preoperative design, and the average operative time of the guides was (29.2±9.8) minutes without complications such as perforation of the bone cortex. Conclusions: The use of sequential sectioning guides to assist in the extraction of mandibular impacted third molars was initially validated to accurately replicate the preoperative sectioning design, and is expected to provide a digital solution to improve surgical precision and ensure safety. Further studies with larger sample sizes are needed to evaluate its accuracy and safety.

OBJECTIVE: To establish and modify quantitative real-time polymerase chain reaction (qPCR)-based serotyping assays to distinguish 97 pneumococcal serotypes. METHODS: A database of capsular polysaccharide ( cps) loci sequences was generated, covering 97 pneumococcal serotypes. Bioinformatics analyses were performed to identify the cps loci structure and target genes related to different pneumococcal serotypes with specific SNPs. A total of 27 novel qPCR serotyping assay primers and probes were established based on qPCR, while 27 recombinant plasmids containing serotype-specific DNA sequence fragments were constructed as reference target sequences to examine the specificity and sensitivity of the qPCR assay. A panel of pneumococcal reference strains was employed to evaluate the capability of pneumococcal serotyping. RESULTS: A total of 97 pneumococcal serotyping assays based on qPCR were established and modified, which included 64 serotypes previously reported as well as an additional 33 serotypes. Twenty-seven novel qPCR serotyping target sequences were implemented in the pneumococcal qPCR serotyping system. A total of 97 pneumococcal serotypes, which included 52 individual serotypes and 45 serotypes belonging to 20 serogroups, could not be identified as individual serotypes. The sensitivity of qPCR assays based on 27 target sequences was 1-100 copies/µL. The specificity of the qPCR assays was 100%, which were tested by a panel of 90 serotypes of the pneumococcal reference strains. CONCLUSION A total of 27 novel qPCR assays were established and modified to analyze 97 pneumococcal serotypes.

This paper summarizes Professor ZHANG Jian-bin's experience in "moving cupping therapy on the back" in clinical practice. Professor ZHANG Jian-bin is good at applying the theory of governor vessel to the clinical diagnosis and treatment. He believes that the moving cupping therapy is the supplementation of "spinal therapy" in clinical diagnosis and treatment. He emphasizes that during the moving cupping therapy exerted, the physicians should observe carefully to in-time obtain the perceived feedback of treatment in patients. Afterward, the cupping marks left should be inspected to discover the location of disorder in the body, thus, a targeted treatment can be provided. Besides, the prognosis of the disease can be judged by the feedback after many treatments with the moving cupping therapy. The moving cupping therapy displays its important value in the diagnosis and treatment of disease, as well as the evaluation of the prognosis.
