Sensorineural hearing loss (SNHL), the most commonly-occurring form of hearing loss, is caused mainly by injury to or the loss of hair cells and spiral ganglion neurons in the cochlea. Numerous environmental and physiological factors have been shown to cause acquired SNHL, such as ototoxic drugs, noise exposure, aging, infections, and diseases. Several programmed cell death (PCD) pathways have been reported to be involved in SNHL, especially some novel PCD pathways that have only recently been reported, such as ferroptosis, necroptosis, and pyroptosis. Here we summarize these PCD pathways and their roles and mechanisms in SNHL, aiming to provide new insights and potential therapeutic strategies for SNHL by targeting these PCD pathways.

Objective To establish the fingerprints and predict the quality markers of Sanqi Shenfeng oral liquid based on fingerprint and network pharmacology.Methods The fingerprints of 12 batches of Sanqi Shenfeng oral liquid were established by using HPLC,and their peaks were identified and assigned.The candidate components were selected by multiple statistical analysis methods such as similarity evaluation,hierarchical cluster analysis,principal component analysis and orthogonal partial least squares discrimination analysis(OPLS-DA).The"component-target-pathway"network diagram was constructed by network pharmacology,and the quality markers of Sanqi Shenfeng oral liquid were predicted.Results The 13 common peaks were identified from the established fingerprint.Compared with the reference material,eight common peaks were identified as 3(tetrahydroxystilbene glucoside),5(sodium benzoate),6(lobetyolin),7(notoginsenoside Ri),9(ginsenoside Rgi),10(ginsenoside Re),12(10-hydroxy-2-decenoic acid),13(ginsenoside Rb1).The similarity of 12 batches of Sanqi Shenfeng oral liquid samples was higher than 0.997,and 12 batches of samples were grouped into two categories.OPLS-DA analysis showed that peaks 2,3,4,7,9,10,11,12 were the main signature components affecting the quality of Sanqi Shenfeng oral liquid.Network pharmacology predicted that lobetyolin,notoginsenoside R1,ginsenoside Rg1,ginsenoside Rb1,ginsenoside Re and 10-hydroxy-2-decenoic acid were potential Q-markers of Sanqi Shenfeng oral liquid.The traditional functions are performed through STAT3/AKT1-Drp1,HIF-1 and PI3K-AKT signaling pathway.Conclusion The established fingerprint has good reproducibility,stability and feasibility.The six components have great influence on the quality of Sanqi Shenfeng oral liquid,which are transferable and traceable,and are closely related to the efficacy.They can be used as potential quality markers to provide a scientific basis for the quality control and evaluation of Sanqi Shenfeng oral liquid.

Objective:To explore the value of prenatal three-dimensional ultrasonography（3DUS）in displaying auricular morphotyping and dimensions for predicting congenital aural atresia（CAA）.Methods:A retrospective collection of 227 fetuses who underwent ultrasound scans and retained auricular 3DUS volumes from January 2018 to December 2023 at the First Affiliated Hospital of Sun Yat-sen University was conducted. Fetuses were divided into two groups：a CAA group（52 fetuses，62 auricles）and a non-CAA group（175 fetuses，202 auricles），based on the presence or absence of external auditory canal identified through postnatal examination. According to 3DUS auricular contour and presence or absence of the concha，the auricles were divided into 4 types：type Ⅰ，C-shaped auricle with a concha；type Ⅱ，Irregular auricle with a concha；type Ⅲ，C-shaped auricle without a concha；type Ⅳ，Irregular auricle without a concha. And auricular length（AL）and width（AW）were measured to calculate the product of the auricular length and width（ALW）. Normal reference ranges for ALW from the non-CAA group were developed. Differences of the auricular morphotyping and Z-score of ALW（ALWZ）were compared between the two groups. Receiver operating characteristic（ROC）curves were used to evaluate the diagnostic efficiency of auricular morphotyping，ALWZ and the regression model. A Logistic regression model for CAA based on auricular morphotyping and ALWZ were established.Results:The auricular morphotyping and ALWZ between the two groups were different statistically（both P<0.05）. The AUC of the auricular morphotyping and ALWZ predicting CAA were 0.960（95% CI = 0.923 - 0.997）and 0.975（95% CI = 0.959 - 0.991）individually. Formula for CAA prediction model combining the two indicators（5.379 × morphotyping - 2.386 × ALWZ - Conclusions:The auricular morphotyping and dimensions can effectively predict CAA.

Objective:To explore the current status and trends in emergency nursing teaching methods based on CiteSpace software in China from 2012 to 2023, and to provide reference for subsequent research.Methods:Literature on teaching methods in emergency nursing was electronically searched in the China National Knowledge Infrastructure, WanFang Data, and VIP from January 2012 to December 2023. CiteSpace and Excel software were used to perform bibliometric analysis on the publication year, journal source, first author affiliation, keywords and clustering content.Results:An initial search yielded 1 550 articles and 936 relevant articles were screened and published in 194 journals. From 2012 to 2023, the number of publications on teaching methods in emergency nursing in China was relatively flat, the first author affiliations were mainly general hospitals, and the research methods were mainly quantitative. Keyword clustering showed that six themes were extracted, including exploration of professional skills, reform and application of teaching methods, nursing teaching and evaluation, teaching modes, teaching tools, and training modes.Conclusions:The trend of publications in emergency nursing teaching methods in China in the past 10 years has been relatively flat, and the quality of the literature needs to be improved. Emergency nursing teaching needs to focus on reforming teaching modes and methods, and further exploring the use of tools such as mind maps and teaching manuals to improve the quality of teaching.

Osteoarthritis(OA)is the most common degenerative disease in clinical practice.Joint pain is the main manifestation of OA,and in severe cases,it can lead to joint deformity.The main pathological changes include destruction of articular cartilage,synovitis,thickening of subchondral bone,bone redundancy,degeneration of articular ligaments,and enlargement of articular periosteum.Clinicopathological changes and pain degrees in OA patients vary from person to person,and treatment options vary from person to person.Clinically,non-steroidal anti-inflammatory drugs are used to treat the pain of OA patients now,but the effect is not ideal,and long-term use of these drugs will bring obvious toxic and side effects.Traditional Chinese medicine obtains good results in relieving the pain of OA patients.Therefore,this paper reviews the research on traditional Chinese medicine treatment and pain mechanisms of OA,with a view to providing ideas and references for clinical relief of pain in OA patients.

BACKGROUND:Intervertebral disc degeneration is the basis of spinal degenerative diseases;however,there is no effective treatment. OBJECTIVE:To investigate whether sinomenine can inhibit interleukin-1β-induced apoptosis in nucleus pulposus cells and its molecular mechanism. METHODS:Rat nucleus pulposus cells were cultured in vitro by trypsin combined with type II collagenase digestion,and the cell growth curve was plotted.An appropriate sinomenine concentration was determined using the cell counting kit-8 kit.Nucleus pulposus cells were divided into control group,sinomenine group,interleukin-1β group,sinomenine+interleukin-1β group,zinc protoporphyrin group,zinc protoporphyrin+sinomenine group,zinc protoporphyrin+interleukin-1β group,and sinomenine+zinc protoporphyrin+interleukin-1β group.Proliferative activity,reactive oxygen species content,apoptosis rate,and heme oxygenase-1 expression in nucleus pulposus cells were detected. RESULTS AND CONCLUSION:The rat nucleus pulposus cells cultured in vitro were polygonal,triangular,and short wedge-shaped,and the cell growth showed an"S"curve.The cells grew slowly in the first 3 days of culture,rapidly in 4-6 days,and slowly again in 7-8 days.The cells then entered the"platform stage"where the number of cells no longer increased.The proliferative activity of myeloid cells showed no significant changes when the concentration of sinomenine was≤80 μmol/L(P>0.05).Interleukin-1β significantly reduced the proliferative activity of nucleus pulposus cells,increased the content of reactive oxygen species and led to apoptosis(P<0.01).Sinomenine intervention not only promoted heme oxygenase-1 expression(P<0.05)but also inhibited interleukin-1β-induced decrease in proliferative activity and increase in reactive oxygen species content and apoptosis rate in nucleus pulposus cells(P<0.05).These effects could be reversed by zinc protoporphyrin(P<0.01).
