Cancer-related cognitive impairment(CRCI)refers to cognitive dysfunction that occurs during or after chemotherapy in patients with cancer.However,the pathogenesis of CRCI remains unclear,and effective treatments are lacking in clinical practice.Based on the"toxin damaging brain collaterals"theory,this study systematically explores the traditional Chinese medicine(TCM)etiology,pathogenesis,and treatment strategies of CRCI.In TCM,CRCI is attributed to a"deficiency of brain collaterals"in patients with cancer.Chemotherapy drugs,as exogenous pathogens,invade the brain when the body is weakened and interact with endogenous phlegm,blood stasis,and turbid toxins.This creates a vicious cycle of"toxin,blood stasis,phlegm,deficiency"ultimately leading to the malnourishment of the sea of marrow and the dysfunction of the spiritual mechanism.Modern biological research aligns with this TCM perspective,as neurotoxicity,oxidative stress,and inflammatory responses associated with CRCI correspond to the TCM concepts of"toxin damaging brain collaterals."Pathological changes such as increased microvascular permeability and neuronal network disruption are similar to the TCM pathogenesis characteristics of"toxin and blood stasis blocking the collaterals"and"emptiness of the sea of marrow."Given the progressive nature of CRCI pathogenesis,TCM therapeutic principles focus on strengthening healthy qi,enhancing cognitive function,eliminating toxins,and unblocking collaterals.Acupuncture,moxibustion,and Daoyin serve as supplementary external treatments,forming a comprehensive treatment approach of"treating the viscera through the collaterals and regulating the body to nourish the spirit."This framework provides novel insights for TCM diagnosis and CRCI treatment.

Mesenchymal stem cells(MSCs)are self-regenerating,rapidly proliferating pluripotent stem cells that depend primarily on their derived pro-angiogenic,inflammatory regulatory,and tro-phic factors to exert beneficial effects that attenu-ate deleterious inflammatory responses,reduce vascular damage,and promote tissue repair and re-generation.Obstructive sleep apnea hypoventila-tion syndrome(OSAHS)is a chronic disorder marked by oropharyngeal collapse during sleep,re-sulting in transient reduced airflow,large fluctua-tions in intrathoracic pressure,and intermittent hy-poxia and hypercapnia.OSAHS subsequently cyto-kine-mediated inflammatory cascades,oxidative stress,and ischemia,recruit MSCs from inflamed and damaged tissues through MSCs-derived of anti-inflammatory and pro-angiogenic factor activity,re-duce hypoxia,suppress inflammation,promote re-generation,and prevent fibrosis in OSAHS-injured tissues.In this paper,we will describe the patho-genesis of inflammation,oxidative stress,fibrosis and ischemia from the perspective of OSAHS,high-lighting the current research progress on MSCs-de-pendent regulation of OSAHS-related pathology.

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 investigate the safety and efficacy of low negative pressure fat suction combined with bipolar radiofrequency in repairing facial fat overfilling.Methods:A total of 29 patients with facial fat overfilling underwent low negative pressure fat suction combined with bipolar radiofrequency between February 2022 and October 2023 in Changsha My Like Medical Cosmetology Hospital. All patients were female. The mean age was 35.7 years (range, 25-51 years) and the mean body mass index was 20.3 (range, 16.8-24.3 kg/cm 2). The mean time after autologous fat transplantation was 53.4 months (range, 19-96 months). Postoperative patient satisfaction surveys were conducted, and 2 independent doctors evaluated clinical effect preoperative and postoperative photographs at 3-6 months postoperatively. Results:There were 29 cases (100%) underwent liposuction in the pre-zygomatic region, and the amount of fat was 4.1-12.6 (7.95±1.85) ml. There were 4 cases (13.8%) underwent liposuction in the forehead, and the amount of fat was 1.8-5.2 (2.75±0.50) ml. There were 7 cases (24.1%) underwent liposuction in the temporal region, and the amount of fat was 2.8-6.5 (3.86±1.07) ml. There were 8 cases (27.6%) underwent liposuction in the cheek, and the amount of fat was 5.2-10.5 (7.25±2.12) ml. There were 18 cases (62.1%) underwent liposuction in the perioral region, and the amount of fat was 3.7-9.5 (6.33±1.28) ml. The energy delivered by bipolar radiofrequency was 3.3-10.2 (5.71±2.27) KJ. 82.8% of patients were satisfied with their postoperative effect (24/29 patients). 86.2% of doctors were satisfied with the postoperative effect (25/29 patients). Two out of 29 patients (6.9%) developed irregularity by liposuction.Conclusions:Low negative pressure liposuction combined with bipolar radiofrequency can effectively reduce the fat, narrow the tissue gap and improve facial sagging, which is an effective method for repairing facial fat overfilling.
