Background: Maturity-onset diabetes of the young (MODY) due to variants of hepatocyte nuclear factor 1-beta (HNF1β) (MODY5) has not been well studied in the Chinese population. This study aimed to estimate its prevalence and evaluate the application of a clinical screening method (Faguer score) in Chinese early-onset diabetes (EOD) patients. Methods: Among 679 EOD patients clinically diagnosed with type 2 diabetes mellitus (age at diagnosis ≤40 years), the exons of HNF1β were sequenced. Functional impact of rare variants was evaluated using a dual-luciferase reporter system. Faguer scores ≥8 prompted multiplex ligation-dependent probe amplification (MLPA) for large deletions. Pathogenicity of HNF1β variants was assessed following the American College of Medical Genetics and Genomics (ACMG) guidelines. Results: Two rare HNF1β missense mutations (E105K and G454R) were identified by sequencing in five patients, showing functional impact in vitro. Another patient was found to have a whole-gene deletion by MLPA in 22 patients with the Faguer score above 8. Following ACMG guidelines, six patients carrying pathogenic or likely pathogenic variant were diagnosed with MODY5. The estimated prevalence of MODY5 in Chinese EOD patients was approximately 0.9% or higher. Conclusion MODY5 is not uncommon in China. The Faguer score is helpful in deciding whether to perform MLPA analysis on patients with negative sequencing results.

This case report presents a 16-year-old male patient with deficiency of adenosine deaminase 2(DADA2). The patient had a history of Raynaud′s phenomenon with digital ulcers since childhood. As the disease progressed, the patient developed retinal vasculitis, intracranial hemorrhage, skin necrosis, severe malnutrition, refractory hypertension, and gastrointestinal bleeding. Genetic testing revealed compound heterozygous mutations in the ADA2 gene (paternal c.1072G > A pathogenic mutation + maternal c.1065C > A variant of unknown clinical significance). ADA2 enzyme activity was significantly reduced (0.1 U/L). A multidisciplinary treatment team developed an individualized plan to address key issues, including nutritional support, blood pressure control, rehabilitation, pain management, and balancing anticoagulation/bleeding risks. After systematic intervention, the patient′s condition showed partial improvement. This case reveals clinical challenges such as anticoagulation decisions and nutritional support of DADA2. It also emphasizes the importance of early molecular diagnosis, tumor necrosis factor-α inhibitor targeted therapy, and multidisciplinary collaboration in management, underlining the core value of precision medicine in rare disease management.

More than 300 million people worldwide suffer from asthma, and the incidence is increasing year by year. As one of the most common chronic diseases, asthma is an immune-mediated inflammatory disease with complex triggering mechanisms and strong heterogeneity. With the in-depth study of physiological and pathological mechanisms, therapeutic small molecule and hormone drugs have been introduced to control and treat most patients, but about 5% - 10% of patients still suffer from various subtypes of difficult to control and treat asthma, that is, severe asthma. In the past decade, with the rapid development of bio-pharmaceutical research, protein and antibody have become the key drugs for the treatment of severe asthma with high efficacy, high specificity and high safety. However, biological drugs are usually administered by injection, they cannot be noninvasive and directly delivered into the lung to quickly absorb and take effect. Therefore, there is an urgent need for the introduction of inhaled biologics with quick effectiveness, convenience, economy and safety in clinical. The review summarizes the existing small molecule, hormone and biological therapy drugs, and summarizes the development of inhalable biological agents of asthma, and analyzes the future prospects of the inhalable biological drugs, which is designed to deepen the perception of the direction of the inhalable biological drugs research, and update the information of the field, in order to provide reference for the development of more inhalable biologics.

Objective To explore the clinical effect of Fu's subcutaneous needling combined with western medicine in the treatment of irritable bowel syndrome(IBS).Methods A total of 112 patients with IBS were randomly divided into the observation group and the control group,with 56 patients in each group.The control group was given conventional western medicine treatment,and the observation group was treated with Chinese medicine Fu's subcutaneous needling on the basis of the treatment in the control group.Both groups were treated for 4 consecutive weeks.After 1 month of treatment,the clinical efficacy of the two groups was evaluated,and the changes in the IBS system severity system(IBS-SSS)scores were observed before and after the treatment,as well as the time of the symptoms of abdominal pain,bloating and diarrhoea subsiding in the two groups,and the changes in the defecation thresholds,pain thresholds,sensory thresholds and the changes in the numbers of intestinal flora such as Bifidobacterium,Lactobacillus,Enterobacteriaceae,and Bacteriodendrobacteriaceae in the two groups were compared.The changes in the levels of vasoactive intestinal peptide,gastric motility and substance P were observed in the two groups.The safety and occurrence of adverse reactions were also evaluated in the two groups.Results(1)The total effective rate of the observation group was 96.43%(54/56),and the control group was 83.93%(47/56).The efficacy of the observation group was superior to that of the control group,and the difference was statistically significant(P＜0.05).(2)The time for abdominal pain,abdominal distension and diarrhoea to subside was significantly shorter in the observation group than in the control group,and the difference was statistically significant when compared with the control group(P＜0.05).(3)After treatment,the defecation threshold,pain threshold,and sensation threshold of patients in the two groups were significantly improved(P＜0.05),and the observation group was significantly superior to the control group in terms of improving defecation threshold,pain threshold,and sensation threshold,and the difference was statistically significant(P＜0.05).(4)After treatment,the numbers of Bifidobacterium,Lactobacillus,Enterobacter,Bacteroides were significantly improved in the two groups(P＜0.05),and the observation group was significantly superior to the control group in terms of improving the numbers of Bifidobacterium,Lactobacillus,Enterobacter and Bacteroides,and the difference was statistically significant(P＜0.05).(5)After treatment,the levels of vasoactive intestinal peptide,gastric actin,and substance P of the patients in the two groups were significantly improved(P＜0.05),and the observation group was significantly superior to the control group in improving the levels of vasoactive intestinal peptide,gastric actin,and substance P,and the differences were all statistically significant(P＜0.05).(6)There was no significant difference in the incidence of adverse reactions between the two groups(P＞0.05).Conclusion Fu's subcutaneous needling combined with western medicine in the treatment of IBS can significantly shorten the relief time of patients'clinical symptoms,strengthen patients'gastrointestinal function,regulate the number of intestinal flora and improve the function of gastrointestinal mucous membrane barrier,and the therapeutic efficacy is remarkable.

Objective To investigate the effect of rats'injuries and its mechanism caused by specific dose of radiation combined with decompression exposure.Methods 81 male SD rats were randomly divided into control group(n=9),radiation group(n=18),radiation+low-load decompression group(n=18),radiation+medium-load decompression group(n=18),and radiation+high-load decompression group(n=18).In addition to control group,the rats were irradiated with 60Co γ rays at 4 Gy and then underwent rapid escape experiments.The high-pressure exposure schemes were to stay underwater 57 m for 30 min,45 min or 60 min and reduce to normal pressure within(30±5)s,respectively.The high-pressure exposure was not carried out in radiation group.The behavior and death of rats in each group were observed 0.5 h after leaving the cabin.Blood(abdominal aorta)and lung tissues were collected at 3 h and 72 h,respectively.The changes of lung wet-dry weight ratio(W/D),lung pathology and serum levels of interleukin(IL)-1β,IL-6,tumor necrosis factor-α(TNF-α),superoxide dismutase(SOD),malondialdehyde(MDA),nitric oxide(NO),intercellular adhesion molecule-1(ICAM-1)and thromboxane B2(TXB2)were analyzed.Results Compared with control group and radiation group,radiation+low-load decompression group showed no significant difference in the injury and death rate of rats(P＞0.05),while radiation+medium-load decompression group and radiation+high-load decompression group showed significantly increase of the injury and death rate of rats(P＜0.05).Compared with control group,other groups showed no significant change in pulmonary W/D at 3 h(P＞0.05),and increased at 72 h(P＜0.05).HE staining showed that compared with control group,radiation group showed mild lung interstitial edema,while radiation+low-load decompression group showed obvious pulmonary tissue edema and a small number of red blood cells exudated in the alveolar cavity.The edema,congestion and inflammatory cell infiltration of lung tissue were more serious in radiation+medium-load decompression group and radiation+high-load decompression group.Compared with control group and radiation group,all radiation+decompression groups showed an increase in serum levels of IL-1β,IL-6,TNF-α,MDA,NO,ICAM-1 and TXB2(P＜0.05),and a decrease in SOD activity(P＜0.05).Compared with radiation+low-load decompression group,radiation+medium-load decompression group and radiation+high-load decompression group showed increase in serum levels of IL-1β,IL-6,MDA,ICAM-1 and TXB2(P＜0.05),and decrease in activity of SOD(P＜0.05).Except for control group,serum levels of IL-1β,IL-6,TNF-α,MDA,NO,ICAM-1 and TXB2 were decreased at 72 h compared with 3 h(P＜0.05),and SOD activity was increased at 72 h in all groups(P＜0.05).Conclusions High-load decompression can increase the injury and death rate of rats exposed to radiation and high pressure.The potential mechanism of the combined injury effect of radiation and decompression was related to inflammation,immune stress,oxidative damage,vasomotor activity and coagulation mechanism.

This article reported a patient who initially presented with insomnia complaints and was subsequently diagnosed with severe obstructive sleep apnea （OSA） on polysomnography （PSG）. The patient tried continuous positive airway pressure （CPAP）but gave up because wear the ventilator made it more difficult to fall asleep. Then the patient only received group cognitive behavioral therapy for insomnia （CBT-I）， which not only alleviated insomnia severity but also promoted severe OSA into mild status. Such case suggested that， firstly， due to the high comorbidity of insomnia and OSA， evaluation of OSA should be considered a part worth enough attention of the clinical diagnosis and treatment of insomnia patients. Secondly， by relieving insomnia， CBT-I can alleviate both nocturnal apnea and daytime somnolence in patients with comorbid insomnia and sleep apnoea （COMISA）， so the application of CBT-I should be emphasized in the treatment of such patients. ［Funded by the Central Government-guided Local Science and Technology Development Fund Project （number， 2022ZY0028）］
