Neurofibromatosis type 1 (NF1) presents with a diverse range of symptoms that can affect the skin, bones, eyes, central nervous system, and other organs. This article reports the diagnosis and treatment process of a patient with NF1 complicated by bilateral severe-to-profound sensorineural hearing loss. Genetic testing revealed a heterozygous variant of NF1 NM_ 000267.3: c.4054_ 4058del(p.Ser1352LeufsTer20, supporting the diagnosis of NF1. After thorough evaluation, a right cochlear implantation was performed, yielding satisfactory postoperative results. This case suggests that NF1 patients may exhibit phenotypic heterogeneity and atypicality, providing a reference for clinicians in the diagnosis and treatment of such patients.

OBJECTIVE: To provide the experience and demonstration for the transformation of acupuncture-moxibustion techniques standards from Chinese national standards to international standards. METHODS: Questionnaire research, literature research, semi-structured interviews and expert consultation were used. RESULTS: The safety of acupuncture-moxibustion techniques was evaluated through literature research, and based on the results of the questionnaire survey, expert interviews, and expert consultation, 11 main bodies and structure of the former Chinese national standard, Technical Benchmark of Acupuncture and Moxibustion: General Rules for Drafting, were adjusted and optimized in accordance with the requirements of international standard (including the language, normative references, purpose, scope, applicable environment, target population, work team, terms and definitions, general principles and basic requirements, structural elements and text structure, and compilation process); and the first international standard, World Federation of Acupuncture-Moxibustion Societis (WFAS) Technical Benchmark of Acupuncture and Moxibustion: General Rules for Drafting was formulated to specify the general rules for drafting. CONCLUSION The 3 key questions, "international compatibility", "technical operability" and "safety" should be solved technically on the basis of explicit international requirements. It is the core technical issue during transforming the national standards of technical benchmark of acupuncture and moxibustion into international standards.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

BACKGROUND:Interleukin-8 is an important cytokine that has been found to play an important role in bone regeneration through multiple pathways. OBJECTIVE:To comprehensively review the action mechanism of interleukin-8 effects on bone regeneration to provide ideas for the following studies on interleukin-8. METHODS:By searching the China National Knowledge Infrastructure database for articles published from January 1999 to February 2023 and PubMed database for articles published from January 1985 to February 2023 reporting the role of interleukin-8 in bone-associated cells and vascularisation.Chinese and English search terms were"interleukin-8,bone repair,bone metabolism,mesenchymal stem cells,osteoblasts,osteoclasts,vascularization".The initial review yielded 508 articles in English and Chinese,and a total of 51 articles were included for review and analysis according to the inclusion and exclusion criteria. RESULTS AND CONCLUSION:According to the existing research,interleukin-8 can promote bone cell regeneration and assist bone healing through multiple pathways,which is mainly divided into three aspects:(1)Promote the proliferation and differentiation of bone cells such as mesenchymal stem cells and osteoblasts,and promote the development of cells in the direction of promoting bone healing;(2)interleukin-8 can promote angiogenesis and provide sufficient nutrition and oxygen for bone tissue,thus further improving the quality and stability of bone healing.(3)The appearance of interleukin-8 facilitates the expression of hypoxia-inducible factor-1α,vascular endothelial growth factor,and matrix metalloproteinase,which can create a microenvironment conducive to bone regeneration,thus promoting the regeneration and repair of bone tissue.In summary,interleukin-8 plays an important role in bone healing by promoting osteoblast proliferation and differentiation,facilitating angiogenesis and improving the mechanical properties of bone regeneration,as well as influencing bone metabolism through osteoclasts,mesenchymal stem cells,and other action sites.

Objective:To investigate the effects of Apelin-13 regulatory peptide on neuronal cell pyroptosis in mice modeled with cerebral ischemia-reperfusion(I/R).Methods:We prepared a mouse cerebral I/R model using middle cerebral artery embolization and Reperfusion(MCAO/R).The HT22 cell injury model was prepared by the oxygen glu-cose deprivation/reoxygenation(OGD/R),and Apelin-13 treatment was also given.Neurological function was assessed by neurological deficit score;hematoxylin-eosin(HE)staining and Nissl staining were used to observe the morphologic changes of the infarcted area of the mice;and 2,3,5triphenyltetrazolium chloride(TTC)staining was used to observe the volume of cerebral infarcts;The expression of NOD-like receptor thermoprotein structural domain-related protein 3(NLRP3),gasdermin D(GSDMD),caspase-1,apoptosis-associated speck-like protein(ASC),interleukin 1β(IL-1β),and interleukin 18(IL-18)in brain tissues from infarcted areas or HT22 cells was detected by Western Blot,and IL-1β and IL-18 were detected by enzyme-linked immunosorbent assay(ELISA)in serum of mice and culture supema-tants;The cell viability and cell damage of HT22 were detected by CCK-8 kit and lactate dehydrogenase(LDH)assay kit,respectively;caspase-1 activity was measured by caspase-1 activity kit in HT22 cells;and the expression of caspase-1 and GSDMD was observed by immunofluorescence staining in HT22 cells.Results:Apelin-13 significantly improved neurological function and cerebral infarct volume in I/R mice,and attenuated pathological damage in the in-farcted area.It also reduced the serum levels of IL-1β and IL-18.In addition,Apelin-13 reduced the expression of mol-ecules such as NLRP3,GSDMD,caspase-1,IL-1β,and IL-18 in the cerebral infarct area of mice.In vitro experiments showed that Apelin-13 significantly increased the viability of OGD/R-treated HT22 cells,decreased caspase-1 activity,and reduced the LDH content,as well as decreased the expression of molecules such as NLRP3,GSDMD,caspase-1,IL-1β,IL-18,and so on,in OGD/R-treated HT22 cells.Conclusion:Apelin-13 inhibits pyroptosis through the NL-RP3/caspase-1/GSDMD pathway in cerebral ischemia/reperfusion mice and thus exerts neuroprotective effects.

Objective To study the expression levels of serum complement C1q/tumor necrosis factor-related protein 6(CTRP6)in women in early pregnancy and to explore its relationship with gestational diabetes mellitus(GDM).Methods Women at the Second Affiliated Hospital of Zhengzhou University from March 2021 to March 2022 were prospectively and consecutively selected from 10 to 13 weeks gestation for outpatient obstetric check-ups.The age,height,weight,and time of last menstruation of pregnant women were collected,and the levels of total cholesterol(TC),triglyceride(TG),high density lipoprotein(HDL),low density lipoprotein(LDL),fasting plasma glucose(FPG),glycosylated hemoglobin(HbA1c),fasting insulin(FINS)and CTRP6 were measured in early pregnancy,and the pre-pregnancy body mass index(BMI),baseline BMI,prenatal BMI,and homeostatic model assessment of insulin resistance(HOMA-IR)were calculated.All pregnant women underwent a 75g oral glucose tolerance test at 24-28 weeks of gestation and were divided into GDM group and normal glucose tolerance(NGT)group according to the test results.The clinical data and laboratory indexes of the two groups in early pregnancy were compared,and the correlation between serum CTRP6 and various indexes in early pregnancy and its relationship with GDM were analyzed.Results A total of 213 maternal cases were enrolled,and 203 cases were completed for follow-up.Among them,52 mothers were diagnosed with GDM,with a GDM prevalence rate of 25.62%.Serum CTRP6,age,pre-pregnancy BMI,baseline BMI,antenatal BMI,TC,LDL,FPG,HbA1c,FINS,and HOMA-IR were higher in GDM group compared to NGT group,with a statistically significant difference(P<0.05).CTRP6 in early pregnancy was positively correlated with age,pre-pregnancy BMI,baseline BMI,prenatal BMI,TG,LDL,FPG,HbA1c,FINS,HOMA-IR,and negatively correlated with HDL(P<0.05).After correcting for age,BMI,glycolipid metabolism index and HOMA-IR,CTRP6 in early pregnancy remained an independent factor in the development of GDM.Conclusion Elevated serum CTRP6 in early pregnancy is associated with GDM and is an independent risk factor for GDM.
