Viral pneumonia is an infectious disease caused by virus invading the lung parenchyma and interstitial tissue and causing lung inflammation， with the incidence rising year by year. Traditional Chinese medicine （TCM） can treat viral pneumonia in a multi-component， multi-target， and holistic manner by targeting the core pathogenesis of pneumonia caused by different respiratory viruses， demonstrating minimal side effects and significant advantages. According to the theory of healthy Qi and pathogenic Qi in TCM， the struggle between healthy Qi and pathogenic Qi and the imbalance between immunity and inflammation run through the entire process of viral pneumonia， and the immunity-inflammation status at different stages of the disease reflects different relationships between healthy Qi and pathogenic Qi. Immune dysfunction leads to the deficiency of healthy Qi， causing viral infections. The struggle between healthy Qi and pathogenic Qi causes immunity-inflammation imbalance， leading to the onset of viral pneumonia. Inflammatory damage causes persistent accumulation of phlegm and stasis， leading to the progression of viral pneumonia. The cytokine storm causes immunodepletion， leading to the excess of pathogenic Qi and diminution of healthy Qi and the deterioration of viral pneumonia. After the recovery from viral pneumonia， there is a long-term imbalance between immunity and micro-inflammation， which results in healthy Qi deficiency and pathogenic Qi lingering. Healthy Qi deficiency and pathogenic Qi excess act as common core causes of pneumonia caused by different respiratory viruses. Clinical treatment should emphasize both replenishing healthy Qi and eliminating pathogenic Qi， helping to restore the balance between healthy Qi and pathogenic Qi as well as between immunity and inflammation， thus promoting the recovery of patients from viral pneumonia. According to the TCM theory of healthy Qi and pathogenic Qi， this article summarizes the immunity-inflammation mechanisms at different stages of viral pneumonia， and explores the application of the method of replenishing healthy Qi and eliminating pathogenic Qi in viral pneumonia. The aim is to probe into the scientific connotation of the TCM theory of healthy Qi and pathogenic Qi in viral pneumonia and provide ideas for the clinical application of the method of replenishing healthy Qi and eliminating pathogenic Qi to assist in the treatment of viral pneumonia.

BACKGROUND:Transcranial magneto-acoustic-electrical stimulation is a novel non-invasive neural regulation technique that utilizes the induced electric field generated by the coupling effect of ultrasound and static magnetic field to regulate the discharge activity of the nervous system.However,the mechanism by which it affects synaptic plasticity in the brain is still not enough. OBJECTIVE:To explore the effect of transcranial magneto-acoustic-electrical stimulation intensity on synaptic plasticity of the prefrontal cortex neural network in mice. METHODS:(1)Animal experiment:Twenty-four C57 mice were equally and randomly divided into four groups:the control group receiving pseudo-stimulation,the 6.35 W/cm2 stimulation group receiving coupled stimulation of 0.3 T,6.35 W/cm2,the 17.36 W/cm2 stimulation group receiving coupled stimulation of 0.3 T,17.36 W/cm2,and the 56.25 W/cm2 stimulation group receiving coupled stimulation of 0.3 T,56.25 W/cm2.The local field potential signals and behavioral correctness were recorded during the execution of T-maze in mice.(2)Modeling and simulation experiments:A neural network model of the prefrontal cortex in mice stimulated by transcranial magneto-acoustic-electrical stimulation was constructed to compare the structural connectivity characteristics of the neural network under different stimulation intensities. RESULTS AND CONCLUSION:Transcranial magneto-acoustic-electrical stimulation could effectively shorten the behavior learning time,improve the working memory ability of mice(P＜0.05),and continue to stimulate the frontal lobe of mice after learning behavior.There was no significant difference in the accuracy of the T-maze behavioral experiment among the experimental groups(P＞0.1).Analysis of local field potential signals in the frontal lobe of mice revealed that transcranial magneto-acoustic-electrical stimulation promoted energy enhancement of β and γ rhythms.As the stimulation intensity increased,there was an asynchronous decrease in β and γ rhythms.Through β-γ phase amplitude coupling,it was found that stimuli could enhance the neural network's ability to adapt to new information and task requirements.Modeling and simulation experiments found that stimulation could enhance the discharge level of the neural network,increase the long-term synaptic weight level,and decrease the short-term synaptic weight level only when the stimulation intensity was high.To conclude,there is a complex nonlinear relationship between different stimulus intensities and the functional structure of neural networks.This neural regulation technique may provide new possibilities for the treatment of related neurological diseases such as synaptic dysfunction and neural network abnormalities.

The principle of treating different diseases with the same therapy is the essence of syndrome differentiation and treatment in traditional Chinese medicine （TCM）. It means that when the same pathogenic changes or the same symptoms appear in the development of different diseases， the same principles or methods can be used for treatment. Due to the complexity and high variability of viral pathogenicity， the precise and effective treatment of different types of viral pneumonia （VP） has always been a research focus and difficulty in modern medicine. VP belongs to the category of external-contraction febrile disease， warm disease， and epidemic in TCM. Haoqin Qingdantang （HQQDD） is a representative formula for clearing heat and dispelling dampness in warm diseases， and its intervention in VP caused by various viral infections has significant effects. This study， guided by the theory of treating different diseases with the same therapy， links the related studies on using HQQDD to treat different types of VP and finds that influenza virus pneumonia （IVP）， severe acute respiratory syndrome （SARS）， and COVID-19 all have a common pathogenic mechanism of dampness-heat at different stages of respective diseases. When these diseases are dominated by damp-heat factors， the use of HQQDD yields remarkable therapeutic effects. Modern pharmacological studies have confirmed that HQQDD can inhibit virus replication， reduce fever reactions， inhibit the expression of inflammatory mediators， and regulate immune balance. Moreover， the sovereign medicine in this formula has excellent antiviral activity， and the formula reflects rich scientific connotations of treating VP. According to the theory of treating different diseases with the same therapy and based on the effective treatment practice and modern pharmacological research of HQQDD for different types of VP， this paper mines the underlying TCM theory of treatment with the same therapy， explores the syndrome differentiation and treatment strategy and effect mechanism of this formula for different types of VP， and analyzes the treatment mechanism and characteristics， with the aim of providing evidence and reference for the clinical application and modern research of HQQDD.

Objective:To evaluate the effect of disulfiram on sepsis-associated encephalopathy (SAE) and the relationship with NOD-like receptor family pyrin domain-containing 3 (NLRP3)/caspase-1 signaling pathway in rats.Methods:Forty-five SPF healthy male Sprague-Dawley rats, aged 8-12 weeks, weighing 200-220 g, were divided into 3 groups ( n=15 each) using a random number table method: sham operation group, SAE group, and SAE+ disulfiram group (SAE+ DSF group). The SAE model was established by by using cecal ligation and puncture in anesthetized rats. SAE+ DSF group received an intraperitoneal injection of 50 mg/kg disulfiram 4 h before the cecal ligation and puncture. The survival status of rats was recorded within 72 h after surgery. Their neurobehavioral scores were assessed and recorded on days 1-3 after surgery. On the 3rd day after surgery, novel object recognition test (cognitive index) and open field test (activity distance and time in the central area) were conducted sequentially. Following the behavioral testing, the rats were anesthetized, and their hippocampi were dissected and isolated to observe the pathological changes in the hippocampal region (using HE staining) and to determine the expression of NLRP3 and caspase-1 (by Western blot) and the expression of interleukin-1beta (IL-1β), IL-18 and tumor necrosis factor-alpha (TNF-α) mRNA (by fluorescent quantitative polymerase chain reaction). Results:Compared with Sham group, the 72-h survival rate and postoperative neurobehavioral scores were significantly decreased, the activity distance and time in the central area of the open field were shortened, and the cognitive index was decreased, the expression of NLRP3, caspase-1 and IL-1β, IL-18 and TNF-α mRNA was up-regulated ( P<0.05), and the pathological damage was marked in the hippocampus in SAE group ( P<0.05). Compared with SAE group, postoperative neurobehavioral scores were significantly increased, the activity distance and time in the central area of the open field were prolonged, the cognitive index was increased, and the expression of NLRP3 and caspase-1 and IL-1β, IL-18 and TNF-α mRNA was down-regulated ( P<0.05), no significant change was found in the 72-h survival rate ( P>0.05), and the pathological damage to the hippocampus was significantly alleviated in SAE+ DSF group. Conclusions:Disulfiram can alleviate SAE in rats, and the mechanism may be related to the inhibition of the NLRP3/caspase-1 signaling pathway.

The research on the mechanism of Chinese materia medica in the treatment of viral pneumonia (VP) is mainly based on the monomer components of Chinese materia medica and TCM compounds. Among them, the monomer components are mainly polyphenols, flavonoids and anthraquinones, which have anti-inflammatory, antiviral, immunomodulatory and antioxidant pharmacological effects. The efficacy of TCM compounds is mainly based on clearing heat, and it has the functions of removing phlegm, removing blood stasis, removing dampness, moistening lung and so on. The intervention of Chinese materia medica in VP mainly involves NF-κB, MAPK, JAK/STAT, PI3K/Akt and other signaling pathways. The mechanism includes regulating oxidative stress, apoptosis, regulating immune function, inhibiting inflammatory response, etc., which can reduce the pathological damage of inflammatory cell infiltration and edema in lung tissue, and achieve the protective effect on lung tissue. The current research models exhibit unclear patterns of syndrome differentiation, and the mechanisms of Chinese materia medica involving multiple targets and pathways are poorly understood. Future research should integrate disease-syndrome combination models to further explore the mechanisms by which TCM regulates multiple targets and pathways, thereby providing insights and methodologies for the treatment of viral pneumonia with Chinese materia medica.

In clinical practice,the diagnosis of hepatocellular carcinoma primarily relies on imaging findings.For cases with atypical imaging features or insufficient diagnostic specificity,pathological analysis remains essential.With the advancement of precision medicine,research focus has expanded from pure diagnostic evaluation to therapeutic efficacy prediction.Imaging-based prognostic biomarkers have emerged as a key research frontier in hepatocellular carcinoma management.Although accurate diagnosis remains paramount,current investigations increasingly prioritize the identification of biomarkers for treatment response prediction and outcome stratification.Recent studies demonstrate that radiological characteristics not only reflect tumor heterogeneity but also carry prognostic implications for hepatocellular carcinoma.These imaging biomarkers enable non-invasive outcome prediction and provide objective evidence to optimize therapeutic decision-making.This comprehensive review summarizes MRI-derived imaging features associated with hepatocellular carcinoma prognosis,aiming to guide personalized treatment strategies and ultimately improve survival outcomes for hepatocellular carcinoma patients.

Objective:To investigate the clinical efficacy and safety of ultrasonic bone scalpel in nasal osteotomy.Methods:A retrospective analysis was conducted on clinical data from the patients who received ultrasonic bone scalpel-assisted nasal osteotomy in the Nasal Plastic & Reconstructive Surgery Department, Plastic Surgery Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College between January 2023 and April 2024. All patients underwent open lateral approach osteotomy using an ultrasonic bone scalpel under direct vision, combined with augmentation rhinoplasty using autologous costal cartilage grafting. Intraoperatively, the nasal dorsum was fully exposed, and the lateral nasal cartilage was separated from the nasal septum, followed by precise bone tissue incision using the ultrasonic bone scalpel. Parameters recorded included operative time, and postoperative complications. Based on the standardized photographs taken before the operation and during the 6-month follow-up after the operation, the observer global aesthetic improvement scale (GAIS) was evaluated by a third-party doctor, with a score ranging from 1 to 5. The smaller the score, the more significant the improvement compared to before the operation. The satisfaction of patients with the surgical outcome was evaluated and classified into four levels: very satisfied, satisfied, dissatisfied, and very dissatisfied.Results:A total of 25 female patients were enrolled, aged 20 to 38 years, with an average age of 27.1 years. All procedures were completed successfully, with a mean operative time of (25.4±4.2) minutes. Postoperative localized swelling of varying degrees was observed. Follow-up ranged from 6 to 18 months, with nasal contour and curvature stabilizing by 6 months postoperatively. No complications, such as infection, nasolacrimal duct, lacrimal sac, medial canthal ligament, nerve injuries, or sensory disturbances, were reported. Two cases exhibited mild nasal bone widening at the 6-month follow-up, though no surgical revision was requested. Significant improvement in external nasal morphology was achieved in all patients, with high satisfaction rates. The patients satisfaction survey showed that 18 cases (72%) were very satisfied and 7 cases (28%) were satisfied with the surgical outcome. GAIS scores reflected positive evaluations [(1.24±0.51) points].Conclusion:The ultrasonic bone scalpel for nasal osteotomy offers the advantages of high-precision cutting and efficient hemostasis. It is highly effective in reshaping the nasal contour, with shorter osteotomy time, reduced intraoperative bleeding, and a lower postoperative complication rate. This study provides some insights into plastic surgeons in optimizing nasal bone modification strategies.

Objective To investigate the factors influencing mood and sleep among special operation personnel,so as to provide evidence for the prevention and intervention of related issues.Methods A total of 600 special operation personnel during their special duty were enrolled by random sampling method.Basic information was collected by a general information questionnaire.Mood and sleep status were evaluated by self-rating anxiety scale(SAS),self-rating depression scale(SDS),and Pittsburgh sleep quality index scale(PSQI).Results Spearman correlation analysis showed that factors associated with anxiety were years of work experience(r=0.099,P=0.016),family residence(r=-0.153,P＜0.001),and sleep status(r=0.199,P＜0.001);the factors associated with depression were relationship with parents(r=-0.134,P=0.001),family residence(r=-0.144,P＜0.001),and sleep status(r=0.122,P=0.003);and the factors associated with sleep were age(r=0.088,P=0.031),years of work experience(r=0.079,P=0.049),and number of children(r=0.083,P=0.043).Binary logistic regression analysis showed that depression was not an influencing factor of sleep(odds ratio[OR]=1.302,95%confidence interval[95%CI]0.759-1.758,P=0.086),while anxiety was an influencing factor of sleep(OR=2.187,95%CI 1.608-4.695,P=0.001).Conclusion The sleep status of special operation personnel investigated in this survey is related to age and years of work experience,and is influenced by anxiety.Therefore,greater attention should be given to sleep issues in the occupational health support of special operations.Additionally,years of work experience,family residence,relationship with parents,and sleep status are related to anxiety and depression among special operation personnel.It is necessary to focus on the mental health of older workers and those with longer tenure.
