Obstructive sleep apnea (OSA) is a common sleep disordered breathing disorder. As a major global public health problem, untreated OSA can lead to a variety of adverse health outcomes, including various cardiovascular and cerebrovascular diseases, metabolic disorders, and psychiatric disorders such as anxiety and depression. Traditional OSA therapies such as positive airway pressure (PAP), weight loss, oral appliance, upper airway surgery, and postural therapy focus on the anatomical factors of OSA. However, the pathogenesis of OSA is heterogeneous, and non-anatomical factors also play an important role in most patients. Although there is no drug with exact efficacy for the treatment of OSA, with the deepening understanding of the pathophysiological mechanism of OSA, more and more clinical studies are devoted to the study of drug treatment of OSA and its complications, and a series of results have been achieved. The following is a review of the relevant studies on drug treatment of OSA in recent years, hoping to provide literature support and theoretical basis for future research on drug treatment of OSA.

Chronic obstructive pulmonary disease (COPD), a respiratory disease characterized by inflammation due to neutrophil infiltration, has become the third leading cause of death worldwide. After the occurrence of COPD, the persistent accumulation of neutrophils can promote the excessive formation of neutrophil extracellular traps (NETs), which plays an important role in local capture and clearance of pathogens, rapid control of infection, and immune regulation. This article mainly introduces the mechanism of COPD occurrence and NETs formation as well as the research progress of NETs in COPD, and summarizes the relevant drug targets for COPD treatment based on NETs, aiming to provide a reference for further research.

Ischemic stroke, a cerebrovascular disease with high incidence, high mortality, high disability rate and high recurrence rate, is an important cause of death and disability of middle-aged and elderly people in China, and imposes a huge burden to society and families. Therefore, it is essential to identify the risk factors associated with ischemic stroke and effectively prevent them. Studies have shown that obstructive sleep apnea is an independent risk factor for ischemic stroke. However, the exact pathological mechanism of their association has not been clarified. With the development of next-generation sequencing technology, more and more studies have focused on intestinal microbiota. They have found that obstructive sleep apnea can cause intestinal microbiota changes, and intestinal microbiota may be closely related to ischemic stroke. Therefore, this paper attempts to investigate the relationship between intestinal flora and ischemic stroke, so as to reveal the potential pathological mechanism of ischemic stroke caused by obstructive sleep apnea.

Objective To investigate the feasibility of the autoregressive integrated moving average model (ARIMA) in analyzing foodborne diseases in Hubei Province and predicting the future trend of foodborne diseases in Hubei Province. Methods Based on the number of reported cases of foodborne diseases in Hubei Province for eight consecutive years (2014-2021), an ARIMA model was constructed using Python software to fit the data. The model was validated and parameters were optimized with data from January 2022 to December 2022. The optimal fitting model was used to predict the incidence and trends of foodborne diseases in 2023. Results The incidence of foodborne diseases in Hubei Province showed seasonal periodicity, and the peak of epidemic was usually in July every year. SARIMA (0,1,0) (2,2,1)12 was determined as the best fitting model. The model extrapolation effect was verified with 2022 data, and MAPE was 23.90 %, indicating that the model extrapolation effect was effective. Conclusion The SARIMA model is effective for short-term prediction of foodborne disease incidence trends in Hubei Province, and can provide a scientific basis for the formulation of foodborne disease prevention and control policies in the coming year.

Objective:To explore the effect and safety of mesenchymal stem cell exosome microneedle introduction in the treatment of melasma.Methods:Thirty cases of female patients with stable melasma in the Department of Dermatology, Changsha Meilai Medical Beauty Hospital, aged (36±5) years and with a disease duration of (42.4±20.7) months, from July 2021 to July 2022, were retrospectively included. According to Fitzpatrick skin typing, 23 cases of type Ⅲ and 7 cases of type Ⅳ were included. All patients were locally anesthetized with lidocaine cream for 30 min, and rolled with a 0.5 mm needle in a zigzag pattern with even force, in the order of the right cheek, the left cheek, the forehead, the nose, the mandible, and the upper lip. During the rolling process, 3 ml of MSC exosome medical liquid wound dressing was applied to the facial skin, and after it was fully absorbed, exosome was locally readministered in the area of melasma. Treatment ended with a slight redness at the site of application. 1 MSC exosome wound dressing was appllied as a cold compress for 15 min after treatment. Treatment was given once every 2 weeks for 6 consecutive sessions. All the patients were followed up at 4 and 12 weeks after the last session, and the area and severity index of melasma (MASI) were scored before and after the treatment, the clinical efficiency and patient satisfaction rate and the incidence of adverse reactions were also counted.Results:At 4 and 12 weeks after the end of treatment, the skin color of all 30 patients was brighter than that before treatment, and no recurrence of melasma symptoms seen. At 12 weeks after the end of treatment, the decrease rate of MASI score was 66.1%, among which the decrease rate of MASI score in patients with type Ⅲ melasma was 63.9%, and the decrease rate of MASI score in patients with type Ⅳ melasma was 63.9%. Among the 30 patients, 1 case was cured, 25 cases showed obvious improved, 4 cases were improved, and no cases were ineffective, with an effective rate of 86.7% (26/30). Five patients were very satisfied, 18 patients were satisfied, 6 patients were generally satisfied, and 1 patient was dissatisfied; the patient satisfaction rate was 76.7% (23/30). No serious adverse reactions occurred in all patients.Conclusions:MSC exosome microneedle introduction is safe and effective in the treatment of melasma without serious adverse reactions.

Abstract: Objective To study severe fever with thrombocytopenia syndrome virus (SFTSV) in tick samples from different species and genera in Suizhou City, Hubei Province, China, and to explore the phylogenetic relationship between ticks and patients sources of viruses at the molecular evolutionary level. Methods In 2016 and 2017, over a continuous two-year period, 1 158 ticks were collected from Suizhou, Hubei, and their species and genera were identified. Meanwhile, 86 serum samples were collected to detect SFTSV RNA by real-time quantitative reverse transcription-PCR. All viral RNA-positive supernatants of tick homogenates were inoculated into Vero cells for viral isolation, and full genome sequencing of isolated strains was conducted. Phylogenetic tree research on SFTSV strains from ticks and cases was performed using the bootstrapped maximum-likelihood (1 000 iterations) method with Molecular Evolutionary Genetics Analysis (MEGA) software, ver. 11.0 to provide confidence estimates. Results Haemaphysalis longicornis, Ixodes sinensis, and Rhipicephalus microplus were the dominant species (95.34%) in Suizhou City, Hubei Province, China. Tick samples were pooled according to their species and developmental stage, yielding 832 pools, of which 4 were positive for SFTSV by qRT-PCR. The overall minimum infection rate (MIR) in the region was 0.35%. One SFTSV strain named HB 2016-P35, was successfully isolated from Haemaphysalis longicornis and demonstrated high homology to 16 previously reported patient-derived viruses in Hubei Province, especially to the human strain HB 2017-49 from the same region, with a genome similarity of 99.9%. In addition, the molecular phylogenetic analysis revealed five distinct SFTSV genotypes in Hubei, covering almost all currently known SFTSV genotypes. Conclusions Some areas of Suizhou City, Hubei Province, demonstrate a relatively low level of SFTSV carrying and transmission by ticks. The new SFTSV strain isolated from ticks exhibits similar genotype characteristics and high sequence homology with viruses carried by cases in surrounding cases. The study suggests that tick-to-human transmission is most likely the pathway for human infection with SFTSV, highlighting the need for continual and long-term monitoring of tick carriage of SFTSV in endemic areas.
