Aim To screen and study the expression of long non-coding RNA (IncRNA) in rats with middle cerebral artery occlusion (MCAO) with MCAO treated with Tao Hong Si Wu decoction (THSWD) and determine the possible molecular mechanism of THSWD in treating MCAO rats. Methods Three cerebral hemisphere tissue were obtained from the control group, MCAO group and MCAO + THSWD group. RNA sequencing technology was used to identify IncRNA gene expression in the three groups. THSWD-regulated IncRNA genes were identified, and then a THSWD-regu-lated IncRNA-mRNA network was constructed. MCODE plug-in units were used to identify the modules of IncRNA-mRNA networks. Gene ontology (GO) and kyoto encyclopedia of genes and genomes (KEGG) were used to analyze the enriched biological functions and signaling pathways. Cis- and trans-regulatory genes for THSWD-regulated IncRNAs were identified. Reverse transcription real-time quantitative pol-ymerase chain reaction (RT-qPCR) was used to verify IncRNAs. Molecular docking was used to identify IncRNA-mRNA network targets and pathway-associated proteins. Results In MCAO rats, THSWD regulated a total of 302 IncRNAs. Bioinformatics analysis suggested that some core IncRNAs might play an important role in the treatment of MCAO rats with THSWD, and we further found that THSWD might also treat MCAO rats through multiple pathways such as IncRNA-mRNA network and network-enriched complement and coagulation cascades. The results of molecular docking showed that the active compounds gallic acid and a-mygdalin of THSWD had a certain binding ability to protein targets. Conclusions THSWD can protect the brain injury of MCAO rats through IncRNA, which may provide new insights for the treatment of ischemic stroke with THSWD.

Objective:To explore the etiological rules of multifactorial refractory infertility patients by association analysis.Methods:A total of 283 patients with refractory infertility met the inclusion criteria from January 2019 to December 2021 in Nanping People's Hospital Affiliated to Fujian University of Traditional Chinese Medicine,were analyzed retrospectively.Using the Apriori algorithm,association rule analysis was performed on 7 etiological fac-tors:fallopian tube obstruction(FTO),intrauterine adhesions(IUA),ovarian dysfunction[diminished ovarian re-serve(DOR),premature ovarian insufficiency(POI)],polycystic ovary syndrome(PCOS),endometriosis(EMT),adenomyosis(AM)and thin endometrium(TE).Further stratified analysis was performed to assess the combina-tions of causes based on the severity of 4 major factors(EMT,FTO,IUA and DOR/POI).Results:①Among 283 patients,EMT(59.0%)and FTO(50.5%)were identified as the most frequent etiological factors,significantly more prevalent than the other causes(P=0.0000,P＜α').②The 5 most common etiological combinations were:FTO with EMT,PCOS with EMT,AM with FTO,DOR/POI with EMT,and AM with EMT.③After stratified analysis,it was found that the following combination of causes was ranked in the top three:with EMT stages I-IV being highly associated with FTO;the degree of merger between low stage with PCOS is high,while the degree of merger be-tween high stage with AM and DOR/POI is high.Different degrees of IUA are highly associated with EMT,FTO and DOR/POI,while severe IUA also being highly associated with TE.Both unilateral and bilateral FTO have a high degree of merger with EMT and AM.DOR and POI have a high degree of merger with EMT,FTO and AM.Conclusions:EMT and FTO are the main causes of refractory infertility.There are correlations among the causes combinations.The etiological factors combined with different stages of endometriosis are also different.These findings underscore the importance of a comprehensive diagnostic framework to address multifactorial etiologies and reduce missed diagnoses.

Objective:To measure and compare the difference of personal attenuation rating (PAR) of the workers wearing foam earplugs before and after the training, and to evaluate the effect of ear protector wearing training on the noise protection.Methods:In February 2023, 94 workers exposed to noise in a machinery manufacturing factory were selected as subjects. The production noise in the workplace was measured and subjects were trained to wear earplugs. The PAR values of wearing 3M 1110 foam test earplugs were measured and recorded before and after the training by using the fit testing of hearing protection device. The differences between the actual PAR values with nominal values and the noise attenuation values in related standards were compared, and the protective effect of hearing protection device before and after training was evaluated.Results:The average age of the subjects was (36.76±11.48) years old, the average length of service was (16.34±11.64) years, and the average exposure time to noise was (15.67±11.64) years. The noise detection results of the subjects' posts were ranged from 80.1 to 94.3 dB (A). The results of subjects wore 3M 1110 foam test earplugs for fit testing showed that the binaural PAR value after training was (19.3±6.4) dB (A), which was significantly higher than that before training (11.1±7.4) dB (A) ( t=13.31, P<0.001). After training, 11 people (11.70%) could reach the corrected noise reduction value (NRR value), 26 people (27.66%) could reach the standard of single noise reduction value (SNR value) ×0.6, and 84 people (89.36%) could reach the standard of (NRR-7) /2. The under protection rate of hearing protectors after training (7.45%) was significantly lower than that before training (45.74%), and the difference of different protection levels before and after training was statistically significant (χ 2=40.83, P<0.001) . Conclusion:It is suggested that enterprises should use the fit testing instead of nominal value estimation to evaluate the noise reduction effect of hearing protection device. Special training on the selection and use of hearing protection device should be strengthened, so as to ensure that workers wear them correctly and improve the protective effect of hearing protection device.
