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.

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.

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.

AIM:To investigate the effects of Shaoyao-Gancao decoction(SGD)on inflammation and mucosal barrier damage in rats with 2,4,6-trinitrobenzenesulfonic acid(TNBS)-induced inflammatory bowel disease(IBD).METHODS:Forty-eight male SD rats were randomly divided into normal group,model group,high-dose(500 mg/kg),medium-dose(250 mg/kg)and low-dose(125 mg/kg)SGD groups,and balsalazide sodium(1 g/kg)group.All rats were pre-administered for 3 d,and on the 4th day of the experiment,they were fasted for 24 h.Except for the normal group,the rats in the other 5 groups were given enema mixed with TNBS(100 mg/kg)and 50％ethanol,and continued to be adminis-tered for 5 d after modeling.After modeling,the disease activity index(DAI)was evaluated.After the experiment,the levels of nitric oxide(NO)and myeloperoxidase(MPO)in serum and colonic tissues of rats were determined.RT-qPCR and Western blot were used to determine tumor necrosis factor-α(TNF-α),cyclooxygenase-2(COX-2),inducible nitric oxide synthase(iNOS)and nuclear factor-κB(NF-κB)in the colon of rats.The expression of tight junction proteins zonu-la occludens-1(ZO-1)and claudin 2 in rat colon tissues was determined by immunofluorescence staining.RESULTS:Compared with normal group,the weight of rats in model group was decreased,the colon was shortened,DAI and colon tissue macroscopic scores were significantly increased(P<0.05),colon pathological injury was serious,and NO and MPO levels in serum and colon tissues of the rats in model group were significantly increased(P<0.05).The mRNA and pro-tein expression levels of TNF-α,COX-2,iNOS and NF-κB in colon tissues were significantly increased(P<0.01),while the expression levels of ZO-1 and claudin 2 were significantly decreased(P<0.01).Compared with model group,the body weight and colon shortening of rats in SGD groups were alleviated,DAI and macroscopic scores of colon tissues were significantly decreased(P<0.05),the pathological damage of colon was improved,and the levels of NO and MPO in se-rum and colon tissues of rats were significantly decreased(P<0.05).The mRNA and protein expression levels of TNF-α,COX-2,iNOS and NF-κB in colon tissues were significantly decreased(P<0.05),while the expression levels of ZO-1 and claudin 2 were significantly increased(P<0.05).CONCLUSION:Treatment with SGD effectively attenuates the inflam-matory response and intestinal mucosal barrier damage caused by TNBS-induced IBD in rats.

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.

Objective To investigate the correlation between monocyte/high-density lipoprotein cholesterol ratio(MHR)and renal tubule injury and decreased renal function in patients with type 2 diabetes mellitus(T2DM).Methods A total of 326 patients with T2DM who were hospitalized in The Department of Endocrinology,Affiliated Hospital of Xuzhou Medical University were enrolled in this study from September 2021 to March 2023.All the participants were divided into three groups according to urinary alpha1 microglobulin to creatinine ratio(MCR)and estimated glomerular filtration rate(eGFR):normal tubules with normal renal function(RTN+RFN,n=177),impaired tubules with normal renal function(RTI+RFN,n=100),and impaired tubules with decreased renal function(RTI+RFD,n=49).Results MHR was higher in RTI+RFD group than in RTN+RFN group and RTI+RFN group.MHR was higher in RTI+RFN group than in RTN+RFN group(P<0.05).Spearman correlation analysis showed that MHR was positively correlated with MCR and UACR(P<0.05),and negatively correlated with eGFR(P<0.05).Logistic regression analysiss showed that MHR and UACR were independent influencing factors for renal tubular injury in T2DM patients,and MHR,UACR and MCR were influential factors for renal function decline in T2DM patients(P<0.05).ROC curve analysis showed that the area under the curve of MHR was 0.794 and 0.779 in predicting tubular injury and renal function decline respectively in T2DM.Conclusions MHR is an influential factor for renal tubular injury and renal function decline.MHR is valuable in the diagnosis of rendl tubular injury and decreased renal function in T2DM patients.

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.

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.
