Aromatic inhalation therapy is a key traditional Chinese medicine （TCM） approach for preventing respiratory infectious diseases. Its foundational theory， "aromatics acting on the spleen"， is deeply rooted in TCM principles and supported by modern medical research. The theory posits that the aromatic properties of medicinals primarily act on the spleen， and the aromatic inhalation therapy achieved its protective effects by modulation of the spleen and spleen channel to enhance the regulation of wei qi， striae and interstices. In TCM， the spleen is considered the mother of the lungs， with the function of nurturing lung； it is also seen as the source of wei qi， responsible for external defense； and the root of healthy qi， forming the foundation of acquired （postnatal） constitution. Thus， preventive strategies for respiratory infectious diseases focus on strengthening the spleen. From a modern medical perspective， the spleen's role in regulating lung immune responses， the shared immune functions of the respiratory and gastrointestinal mucosa， and the spleen's overall immune modulation provide scientific evidence for using aromatic inhalation therapy to prevent respiratory infections. Additionally， aromatic inhalation therapy offers several advantages， including direct action， rapid onset， minimal side effects， controllable risks， convenience， and ease of dissemination， making it a practical and effective preventive measure for respiratory infectious diseases.

Aromatic Chinese medicinal essential oils are volatile oils extracted from aromatic Chinese herbs， which can prevent and treat respiratory infectious diseases through multiple synergistic mechanisms including pathogen inhibition， immune regulation， and inflammatory response regulation. Essential oils are primarily used externally on the body to prevent infections and alleviate symptoms through methods like inhalation， smearing， topical application， bathing， gargling or as a suppository. They can also be utilized in the environment for disinfection and air purification， through methods like diffusion， vaporization， or spraying. The external application of essential oils extracted from Chinese aromatic herbs has the advantages of convenience， quick absorption， and simultaneous influence on both the body and mind. However， there are still challenges and deficiencies in aspects such as the positioning of functions， indications， safety， and the research on the mechanism of action. It has been proposed to combine the theory of aromatic Chinese medicinals with the characteristics of essential oils， and formulate prescriptions of Chinese medicinal essential oils under the principles of traditional Chinese medicine syndrome differentiation， and prevent and treat respiratory infectious diseases efficiently， accurately， and safely， thereby expanding the clinical application of aromatic Chinese medicinals and the preventive theory of traditional Chinese medicine.

ObjectiveTo compare the effectiveness and mechanism of Xiangzhu Fanggan Formula （香术防感方） by sniffing and nasal drops for preventing influenza A H1N1flu. MethodsFifty-six BALB/c mice were randomly divided into normal group， model group， zanamivir group， high-concentration sachet group， low-concentration sachet group， high-concentration nasal drops group， and low-concentration nasal drops group， with 8 mice in each group. In the low- and high-concentration sachet groups， 15 g and 30 g of Xiangzhu Fanggan Formula sachet were used for sniffing for 24 h per day； while in the low- and high-concentration nasal drops groups， nasal drops of Xiangzhu Fanggan Formula were given at a concentration of 0.11 and 0.22 g/ml， 20 μl each time， twice a day； in the zanamivir group， zanamivir was given at a concentration of 1.025 mg/ml of 20 μl each time， twice a day； in the normal group and the model group， nasal drops of normal saline were given at 20 μl each time， twice a day. Each group was given prophylactic intervention for 5 days. On day 5， 1 h after the administration of the drug， the mice in all groups except the normal group received 35 μl of 50 LD₅₀ A/PR/8/34/H1N1 viral solution as nasal drops to prepare influenza A H1N1 model mice. The body mass of the mice was recorded and the rate of change of body mass was calculated daily from day 5 to day 9 of the experiment， and the general status was observed. The mice were sampled on day 9， and the lung index and the inhibition rate of lung index were calculated； HE staining was used to detect pathological changes in lung tissues and to score lung tissue lesions； RT-qPCR was used to detect viral load in lung tissues； and ELISA was used to detect secretory immunoglobulin A （sIgA） and serum tumour necrosis factor α （TNF-α） and interleukin 2 （IL-2）， interleukin 6 （IL-6）， and interferon γ （IFN-γ） in the lavage fluid of the upper respiratory tract. ResultsOn days 7， 8 and 9 of the experiment， the rate of change in body mass of mice in the model group significantly lower than that in the normal group at the same time points （P＜0.05 or P＜0.01）. On days 8 and 9 of the experiment， the rate of change in body mass of mice in the zanamivir group and the high-concentration nasal drops group increased when compared with the model group （P＜0.05 or P＜0.01）. Compared with the normal group， mice in the model group had significantly higher lung index， lung tissue lesion score， lung tissue viral load， significantly higher serum TNF-α， IL-6， IL-2， IFN-γ levels， and significantly lower sIgA levels in the upper respiratory lavage fluid （P＜0.01）. Compared with the model group， the lung index and lung tissue viral load reduced， serum IFN-γ， TNF-α， IL-2， IL-6 levels reduced， and sIgA levels increased in the zanamivir group and the high-concentration nosal drops group （P＜0.05 or P＜0.01）； except for low-concentration sachet group， lung tissue lesion scores of the drug intervention groups reduced compared with those of the model group （P＜0.01）. Compared with the zanamivir group， the lung index increased in the low-concentration sachet group and the low- and high-concentration nasal drops groups， and the serum TNF-α and IL-2 levels increased in all Xiangzhu Fanggan Formula intervention groups （P＜0.05 or P＜0.01）. Compared with high-concentration nasal drops group， serum TNF-α and IFN-γ levels elevated in the high-concentration increased group， and lung tissue viral load elevated in the low-concentration nasal drops group （P＜0.05 or P＜0.01）. The lung index inhibition rate was 80.84% in the zanamivir group， 41.61% and 17.90% in the high- and low-concentration sachet groups， and 35.40% and 25.40% in the high- and low-concentration nasal drops groups， respectively. HE staining showed that the lung tissues of the model group showed thickening of alveolar septa， alveolar collapse， and infiltration of inflammatory cells； whereas， in each drug intervention group， the inflammation of the lung tissues of the mice and the damage reduced， and the most obvious improvement was in the zanamivir group and the high-concentration nasal drops group. ConclusionXiangzhu Fanggan Formula by sniffing and nasal drops could both prevent influenza A H1N1 virus infection， with antiviral and anti-inflammatory effects， also could improve the pathological damage of lung tissue， and improve the immunity of respiratory mucosa. The nasal drops may be better than sachets in inhibiting inflammatory response， especially the high-concentration nasal drops showed more effective.

Objective·To develope an auditory brainstem implant(ABI)vocoder based on cochlear implant(CI)vocoder characteristics and ABI electrode array topology,and to verify its reliability.Methods·An"n-of-m"coding strategy CI/ABI vocoder was constructed based on MATLAB.Within each frame,only the envelopes of the n channels with the highest energy were selected.The interaction coefficient(IC)(range:1?3),channel numbers(range:5?22),and electrode array topology(CI/ABI)were adjustable parameters,allowing for the synthesis of simulated speech.Psychoacoustic evaluation was employed,recruiting normal hearing subjects to perform closed-set simulated phoneme perception.The phoneme recognition accuracy(20 vowel questions/condition,11 consonant questions/condition)was compared with the corresponding conditions of CI and ABI from reference literature to determine the IC value of the vocoder and verify its reliability.Results·The vocoder successfully synthesized all test stimuli.In the closed-set CI-simulated speech recognition,the simulated vowel and consonant recognition accuracy for IC2 and IC3 conditions showed no significant difference compared to the accuracy reported in the CI reference literature(P＞0.05).The difference in vowel and consonant accuracy between IC2 and the literature was smaller than that between IC3 and the literature(vowel|d|=1.6%vs.20%,consonant|d|=8.4%vs.9.9%),thus determining the optimal interaction coefficient of this model as 2.Subsequently,when modifying the electrode array topology to ABI,it was found that the simulated phoneme recognition accuracy for a 16-channel ABI was significantly lower than that for the 16-channel CI group,consistent with the reported literature.The simulated vowel and consonant accuracy within the 5?8 channel range for ABI showed no significant difference(P＞0.05),also aligning with the trend reported in the literature.Conclusion·A CI/ABI vocoder based on"n-of-m"coding strategy is established and the optimal IC is determined.The established ABI encoder has been evaluated for high reliability through psychoacoustic experiments.It provides suitable technical means for validating ABI-specific coding strategies.

Fenugreek is a kind of Chinese herbal medicine with great development prospects.At present,there are many modern reports on its components extraction,quality standards,processing technology and pharmacological effects.However,there is still a lack of research on sorting out and analyzing the relevant ancient records,and people's herbological cognition of fenugreek is still controversial and incomplete.In this study,through systematic review and analysis of ancient records,the names,original plant,processing methods and properties(including nature,flavor,meridian tropism,action,application,toxicity and contraindication)of fenugreek were comprehensively verified for the first time,which provided a herbological reference for further development,utilization and in-depth study of Fenugreek.It is found that fenugreek has several names such as Kudou,Luba,Huba and Jidou.Based on analyzing the descriptions and pictures of fenugreek original plant in ancient records,there is a strong likelihood that the ancient and modern medicinal fenugreek belong to the same species.In addition to the current common method of stir-frying with salt solution,the ancient books also recorded eight processing methods of fenugreek,such as stir-frying,steaming,baking,and calcining.According to the research of properties,it is found that fenugreek is warm-hot in nature,bitter,sweet,and pungent in flavor,and attributive to the kidney,stomach,liver and bladder meridians.In addition to the efficacy recorded in pharmacopoeia,this study also complemented fenugreek's actions of"improving hearing and eyesight,guiding fire to origin"and application of"fullness and discomfort in abdomen and hypochondrium".According to the textual research of toxicity and contraindication,fenugreek has been recorded as non-toxic in the past dynasties,but it should be used cautiously in the excess-heat syndrome,Yin deficiency syndrome,and pregnant women.

Lumbar spondylolysis is one of the common diseases of low back pain caused by spinal surgery. Its treatment options vary depending on different conditions, from early conservative ones to late surgical ones. There are still disputes over various conservative treatments, choice of surgical methods and the biomechanics of different internal fixation techniques to repair spondylolysis. Therefore, this review summarizes the clinical outcomes of previous clinical treatments of lumbar spondylolysis and the biomechanical characteristics of various techniques to find the mechanical and evidence-based clinical data that may facilitate the treatment of lumbar spondylolysis.

Background and Objectives: Circulating endothelial progenitor cells (EPCs) participate in vascular repair and predict cardiovascular outcomes. The aim of this study was to investigate the correlation between EPCs and abdominal aortic aneurysms (AAAs). Methods: and Results: Patients (age 67±9.41 years) suffering from AAAs (aortic diameters 58.09±11.24 mm) were prospectively enrolled in this study. All patients received endovascular aneurysm repair (EVAR). Blood samples were taken preoperatively and 14 days after surgery from patients with aortic aneurysms. Samples were also obtained from age-matched control subjects. Circulating EPCs were defined as those cells that were double positive for CD34 and CD309. Rat models of AAA formation were generated by the peri-adventitial elastase application of either saline solution (control; n=10), or porcine pancreatic elastase (PPE; n=14). The aortas were analyzed using an ultrasonic video system and immunohistochemistry. The levels of CD34＋/CD309＋ cells in the peripheral blood mononuclear cell populations were measured by flow cytometry. The baseline numbers of circulating EPCs (CD34＋/CD309＋) in the peripheral blood were significantly smaller in AAA patients compared with control subjects. The number of EPCs doubled by the 14th day after EVAR. A total of 78.57% of rats in the PPE group (11/14) formed AAAs (dilation ratio ＞150%). The numbers of EPCs from defined AAA rats were significantly decreased compared with the control group. Conclusions EPC levels may be useful for monitoring abdominal aorta aneurysms and rise after EVAR in patients with aortic aneurysms, and might contribute to the rapid endothelialization of vessels.
