Objective: To investigate the age, period, and birth cohort effect of the incidence, mortality, and disability-adjusted life years (DALY) of oral cancer among the Chinese elderly from 1992 to 2021. Methods: Data on oral cancer incidence, mortality, and DALY rate in the Chinese population aged ≥60 years from 1992 to 2021 were collected from the Global Burden of Disease 2021 (GBD 2021) database. The trends in the incidence, mortality, and DALY rate of oral cancer were analyzed using the average annual percent change (AAPC) and the age-period-cohort (APC) model. Results: The incidence, mortality, and DALY rates of oral cancer among the Chinese elderly showed increasing trends (AAPC=2.262%, 0.548% and 0.360%, all P<0.05) from 1992 to 2021. The APC model revealed that the incidence, mortality, and DALY rate of oral cancer increased with age, peaking in the 85-<90 age group at 22.31/100 000, 16.69/100 000, and 171.41/100 000, respectively. Using the period 2002-2006 as the reference group, the risks of incidence, mortality, and disability of oral cancer showed increasing trends over time. The highest risk of incidence was observed in 2017-2021 (RR=1.450, 95%CI: 1.398-1.504), while the peak risks of mortality (RR=1.131, 95%CI: 1.097-1.166) and disability (RR=1.146, 95%CI: 1.118-1.175) both occurred in 2012-2016. With the 1925-1929 birth cohort as the reference group, the risk of oral cancer incidence showed an increasing trend with later birth years. The highest risk of incidence was observed in the 1955-1959 birth cohort (RR=1.788, 95%CI: 1.699-1.881). In contrast, the risks of mortality and disability exhibited relatively stable trends overall. Conclusions The disease burden of oral cancer among the Chinese elderly generally exhibited an increasing trend from 1992 to 2021, with particularly high burden observed among the elderly aged 85-<90 years. The incidence risk increased with time and year of birth.

Through collecting the existing clinical evidences on acupuncture and moxibustion for urticaria, the distribution of evidence in this field was mapped. A systematic search of Chinese and English literature was conducted in CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, and Cochrane Library for treatment of urticaria with acupuncture and moxibustion, published up to December 31, 2023 since inception of each database. The research status in this field was summarized using an evidence mapping approach, and methodological quality was assessed. A total of 323 randomized controlled trials (RCTs) and 22 systematic reviews were included. The number of studies on acupuncture and moxibustion for urticaria has been increasing, with a significant rise in recent years. In most RCTs, the study scale was small, and the subjects focused on chronic spontaneous urticaria in adolescents and middle-aged adults, aged 14 to 60 years. Regarding the intervention measures, the single therapy of acupuncture and moxibustion was predominant such as acupoint injection, acupoint embedding thread, and filiform needling. In acupuncture with filiform needles, the commonly used acupoints were Quchi (LI11), Xuehai (SP10), Sanyinjiao (SP6), Zusanli (ST36) and Hegu (LI4). The main outcome measures referred to effectiveness rate, score of disease severity, recurrence rate, laboratory indexes, and score of quality of life; and the short-term effect was evaluated specifically. The overall methodological quality of the included studies was relatively low. It is suggested that the future research should focus on large-scale, multi-center, high-quality clinical trials, optimize the protocols for acupuncture and moxibustion intervention, standardize the outcomes, and draw the attention to the evaluation of long-term efficacy, so as to provide clinical evidences of high certainty for urticaria treated with acupuncture and moxibustion.

Objective To investigate the early predictive value of combined detection of serum sodium,heparin-binding protein-to-albumin ratio(HBP/ALB)and interleukin-10(IL-10)in Ka-wasaki disease shock syndrome(KDSS)caused by Kawasaki disease in children.Methods A total of 105 children with KDSS caused by Kawasaki disease(KDSS group)and 105 children with Kawasa-ki disease(control group)were selected as study subjects.Clinical data,serum sodium levels,HBP/ALB and IL-10 levels were compared between the two groups.Multivariate logistic regression a-nalysis was used to screen the influencing factors of KDSS caused by Kawasaki disease in children a-mong serum sodium,HBP/ALB and IL-10.Receiver operating characteristic(ROC)curve analysis was conducted to evaluate the predictive value of traditional prediction schemes(coronary artery dam-age and IVIG resistance)and new prediction schemes(serum sodium and HBP/ALB,IL-10)for KDSS caused by Kawasaki disease in children.Results The proportion of patients with coronary ar-tery damage and IVIG resistance was significantly higher in the KDSS group than those in the control group(P＜0.05).Serum sodium levels were lower,while HBP/ALB and IL-10 levels were higher in the KDSS group compared to the control group(P＜0.05).Multivariate logistic regression analysis showed that serum sodium,BP/ALB and IL-10 were influencing factors of KDSS caused by Kawasaki diseasein children(P＜0.05).For traditional prediction schemes,the areas under the curves(AUCs)for coronary artery damage,IVIG resistance and their combination in predicting KDSS caused by Kawasaki disease were 0.795,0.676 and 0.873,respectively(P＜0.05);for new prediction schemes,the AUCs for serum sodium,HBP/ALB,IL-10 and their combination in predicting KDSS were 0.767,0.824,0.760 and 0.945,respectively(P＜0.05).The AUC for the combination of serum sodium,HBP/ALB and IL-10 was greater than that for the combination of coronary artery dam-age and IVIG resistance(P＜0.05).Conclusion Decreased serum sodium,elevated HBP/ALB and elevated IL-10 are associated with KDSS caused by Kawasaki disease in children.Combined prediction using serum sodium,HBP/ALB and IL-10 has a high predictive value for KDSS caused by Kawasaki disease in children.

BACKGROUND:Sarcopenia is a comprehensive condition of aging induced decline in skeletal muscle mass and strength and represents a major health challenge for the elderly.Accumulating evidence suggests that mitochondrial dysfunction plays a key role in the pathogenesis of sarcopenia.OBJECTIVE:To summarize the mechanisms by which dysregulation of mitochondrial quality control leads to sarcopenia and to explore whether mitochondrial transplantation may be a potential target for the treatment of sarcopenia.METHODS:We searched PubMed and CNKI databases for relevant articles published from 2009 to 2023 using the keywords "sarcopenia,mitochondrial dysfunction,mitochondrial quality control,mitochondrial transplantation,limitations."RESULTS AND CONCLUSION:Given the key role of mitochondrial dysfunction in the pathogenesis of sarcopenia,mitochondrial transplantation may serve as a possible strategy for the treatment of sarcopenia by improving mitochondrial bioenergetics and modulating mitochondria related signaling pathways.Although some preclinical and clinical studies have confirmed the potential of mitochondrial transplantation for the treatment of various diseases,there are still some urgent questions regarding the specific details of mitochondrial transfer.

AIM:To explore the effect of sinomenine hydrochloride(SH)on microcirculation and renal func-tion in type 2 diabetic db/db mice with a focus on the diacylglycerol(DAG)/protein kinase C(PKC)signaling pathway.METHODS:Eighteen 6-week-old male db/db mice were randomly divided into three groups:model group(saline),LY group(administered with 1 mg·kg-1·d-1 LY333531),and SH group(administered with 124.8 mg·kg-1·d-1 SH).Addi-tionally,6 age-matched db/m mice comprised the control group(saline).Daily intragastric administration lasted 6 weeks.Body mass,fasting blood glucose(FBG),urinary microalbumin(mALB),urinary creatinine(UCr)and urinary β2-micro-globulin(β2-MG)were measured in each group.The serum levels of endothelin-1(ET-1),endothelial nitric oxide syn-thase(eNOS),collagen type Ⅳ(Col Ⅳ)and laminin(LN),and the levels of DAG and PKC in renal tissues were ana-lyzed by enzyme-linked immunosorbent assay(ELISA).The morphological changes of renal tissues were assessed using HE and PAS staining,and kidney ultrastructure was examined via transmission electron microscopy.Immunohistochemis-try and Western blot were used to detect PKC and p-PKC levels in renal tissues.RESULTS:Compared with model group,the mice in both LY and SH groups showed decreased body mass(P＜0.05),with significantly reduced FBG level in LY group(P＜0.01).In addition,the urinary mALB and β2-MG levels were markedly decreased(P＜0.01),while UCr level was significantly increased(P＜0.01).Serum ET-1,Col Ⅳ and LN levels were significantly lower(P＜0.01),whereas eNOS level was notably higher(P＜0.01).Renal tissue DAG and PKC levels,as well as p-PKC expression were significantly reduced(P＜0.01).Improvements in renal tissue pathology and ultrastructure were observed.CONCLU-SION:Sinomenine hydrochloride improves microcirculation in diabetic db/db mice by modulating DAG/PKC signaling pathway,thus exerting protective effect on the kidney.

AIM:To investigate the mechanism by which exosomes(EXOs)derived from neural stem cells(NSCs)pretreated with astragaloside IV(ASIV)alleviate brain damage in rats after ischemic stroke.METHODS:Rat NSCs were isolated from fetal rats within 24 h of birth,cultured for 3 d,and subsequently treated with ASIV for additional 5 d.The EXOs from untreated NSCs and ASIV-pretreated NSCs(ASIV-EXOs)were isolated via ultracentrifugation of the cell supernatant.These EXOs were characterized using Western blot to detect specific markers such as CD63,tumor sus-ceptibility gene 101(TSG101)and calnexin.Nanoparticle analysis was employed to determine the size,and the morpholo-gy of the EXOs was observed under electron microscope.Six to eight-week-old SD male rats were randomly assigned to 6 groups:sham group,middle cerebral artery occlusion/reperfusion(MCAO/R)model group,edaravone(EDA)treatment(MCAO/R+EDA)group,EXOs treatement(MCAO/R+EXOs)group and ASIV-EXOs treatment(MCAO/R+ASIV-EXOs)group.Tail vein injections were administered within 2 h following the successful establishment of the MCAO/R model.The Zea Longa method was utilized to evaluate neurological deficits,while the TTC method was employed to assess brain infarc-tion.Pathological changes were examined through HE staining,and TUNEL and caspase-1 immunofluorescence double staining were conducted to detect cellular pyroptosis.Serum levels of interleukin-1β(IL-1β)and IL-18 were measured us-ing ELISA,and Western blot was performed to evaluate the expression of caspase-1,nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3),apoptosis-associated speck-like protein containing a caspase recruitment domain(ASC),gasdermin D(GSDMD),and IL-18 proteins in the ischemic area of the rat cerebral cortex across all groups.RE-SULTS:The MCAO/R group exhibited significantly higher neurological deficit scores compared to the sham group(P＜0.01)and lower scores in the administered groups relative to the MCAO/R group(P＜0.05).Cerebral infarction was mark-edly increased in the MCAO/R group compared to the sham group(P＜0.01),whereas the infarction area was reduced in the administered groups compared to the MCAO/R group(P＜0.05).Serum levels of IL-1β and IL-18 were significantly el-evated in the MCAO/R group versus the sham group(P＜0.01)and were lower in the administered groups compared to the MCAO/R group(P＜0.01).Moreover,IL-1β and IL-18 levels in the MCAO/R+ASIV-EXOs group were lower than those in the MCAO/R+EXOs group(P＜0.05).HE staining revealed pronounced sieve-like infarction foci in the ischemic area of the rat cerebral cortex in MCAO/R group,characterized by disorganized neuronal arrangements,reduced or absent Nys-trom's vesicles,shrunken or fragmented nuclei,and numerous red neurons.In contrast,drug-treated groups exhibited milder pathological changes with clearer neuronal structures and a significant reduction in red neuron counts.Immunofluo-rescence double staining indicated a significant increase in double-positive cells in the MCAO/R group compared to the sham group(P＜0.01),with a decrease in double-positive cells in the administered groups relative to the MCAO/R group(P＜0.05)and a further reduction in the MCAO/R+ASIV-EXOs group compared to the MCAO/R+EXOs group(P＜0.05).The expression levels of caspase-1,NLRP3,ASC,IL-18 and GSDMD proteins in the ischemic region of the rat cerebral cortex were significantly reduced in the administered groups compared to the MCAO/R group(P＜0.01),with further re-duction observed in the MCAO/R+ASIV-EXOs group compared to the MCAO/R+EXOs group(P＜0.05).CONCLU-SION:Exosomes derived from ASIV-pretreated NSCs attenuate brain damage in ischemic stroke rats,potentially through a mechanism involving the inhibition of pyroptosis mediated by the NLRP3/caspase-1 pathway.

Objective:To explore the dilemmas of caregivers in managing pulmonary rehabilitation exercises in children with post-infectious bronchiolitis obliterans, so as to provide guidance for the development of a pulmonary rehabilitation exercise program.Methods:This study utilized the descriptive qualitative research method. From August to December 2023, 22 primary caregivers of children with post-infectious bronchiolitis obliterans in the First Affiliated Hospital of Guangzhou Medical University were selected by purposive sampling method as study subjects for semi-structured interviews. The information was analyzed using the Colaizzi 7-step analysis.Results:A total of three themes and nine sub-themes were distilled, including information (concern for information on pulmonary rehabilitation exercise showing dynamic changes with the course of the disease, access to information on disease diagnosis and treatment and pulmonary rehabilitation exercise management through non-professional channels, biased perceptions of pulmonary rehabilitation exercise, and lack of a unified guide to information on pulmonary rehabilitation exercise) ; motivation (physiological and psychological barriers in the management and implementation of pulmonary rehabilitation exercises, lack of comprehensiveness and continuity of professional instruction in pulmonary rehabilitation exercises, and insufficient communication and collaborative support among family members) ; and behavioral skills (insufficient mastery of respiratory training methods with complex procedures, and lack of the ability to effectively plan a pulmonary rehabilitation exercise program) .Conclusions:Caregivers of children with post-infectious bronchiolitis obliterans face certain dilemmas in managing pulmonary rehabilitation exercises. It is necessary to improve caregivers' awareness of the benefits of pulmonary rehabilitation exercise, strengthen their perception of exercise benefits, and enhance their training in pulmonary rehabilitation exercise skills, pay attention to children's exercise preferences, and perfect the social support system for diseases to promote the implementation of pulmonary rehabilitation exercise in children.
