Lung cancer， with persistently high incidence and mortality rates， remains a significant global health challenge. By taking the study on the experience in diagnosis and treatment of lung cancer with phlegm-dampness and blood stasis syndrome by distinguished traditional Chinese medicine physicians of the Sichuan School as an example， the diagnosis and treatment system for lung cancer with phlegm-dampness and blood stasis syndrome， which was formed in response to the humid and foggy environment of the Sichuan Basin， possesses unique value. However， traditional inheritance modes face challenges such as fragmentation， lack of standardization， and insufficient quantification， which hinder the promotion and application of this experience. This research focused on how to leverage multimodal data and artificial intelligence-generated content （AIGC） to achieve precise analysis， intelligent inheritance， and clinical innovation of the experience in diagnosis and treatment of lung cancer with phlegm-dampness and blood stasis syndrome by distinguished traditional Chinese medicine physicians of the Sichuan School. By integrating multimodal data （encompassing four diagnostic methods of traditional Chinese medicine， modern medical imaging， clinical laboratory tests， molecular biology， and regional environmental information）， a precise diagnosis and treatment system integrating macro and micro perspectives for the "disease， syndrome， and pathogenesis" was constructed. The research yielded the following results： （1） In precise syndrome differentiation， the objective quantification of the phlegm-dampness and blood stasis syndrome was achieved. By constructing a "four diagnostic methods， imaging， and molecule" correlation model， the study revealed intrinsic links between tongue and pulse parameters and the tumor microenvironment， as well as between regional climatic factors and syndrome characteristics， enabling real-time dynamic monitoring of efficacy. （2） In elucidating patterns， the study systematically explored the syndrome differentiation thoughts of Sichuan School physicians， such as the timing of purgation and tonification. A "pathogenesis， syndrome complex， and prescriptions and herb" network model was constructed， which accurately elucidated the synergistic action mechanisms of core herb pairs and quantified the dynamic compatibility patterns of reinforcing healthy Qi and eliminating pathogenic factors. （3） In intelligent empowerment， an auxiliary system integrating intelligent syndrome differentiation， treatment plan generation， and efficacy evaluation was built. This system can fuse regional characteristics with individual data， dynamically generate and optimize personalized prescriptions aligned with the experience of Sichuan School， and predict efficacy trends and potential adverse reactions. The integration of multimodal data and AIGC can effectively facilitate the structured inheritance and clinical translation of distinguished physicians' experience. The established intelligent diagnosis and treatment model integrating traditional Chinese medicine and Western medicine demonstrates clear potential in prolonging patients' progression-free survival， alleviating symptoms， and reducing adverse reactions to treatment. This study provides a referential methodological framework for the traditional Chinese medicine experience in diagnosis and treatment of lung cancer， especially the empirical inheritance and modernized development of regional academic schools. It contributes to advancing clinical diagnosis and treatment toward greater precision and personalization.

Objective:To explore the role of P2Y1Receptor(P2Y1R)-activated astrocytes in delayed encephalopathy after acute carbon monoxide poisoning(DEACMP).Methods:SD rats were randomly divided into Control,DEACMP,DEACMP+DMSO,and DEACMP+MRS2179 groups.The latter three groups were exposed to static CO inhalation to establish the DEACMP model,while the Control group inhaled air.The rats in DEACMP+MRS2179 group were injec-ted with 3 μl of P2Y1R antagonist MRS2179 with concentration of 1 mmol/L via lateral ventricle,while the DEACMP+DMSO group an equal volume of DMSO.At 14 and 21 day after DEACMP model establishment,the spatial learning and memory ability of rats were observed by Morris water maze,the injury of pyramidal cells in the CA1 area of the hippo-campus was observed by HE staining.The protein levels of glial fibrillary acidic protein(GFAP)and P2Y1receptor(P2Y1R)in the hippocampal tissues of rats were detected by immunohistochemistry and Western blot.The expressions of interleukin-1β(IL-1β),interleukin-6(IL-6)and tumor necrosis factor-α(TNF-α)in the hippocampal tissues of rats were detected by ELISA.Results:In comparison with the Control group,the escape latency was found to be signifi-cantly prolonged in the DEACMP group and the DEACMP+DMSO group.Furthermore,the expression levels of GFAP,P2Y1R,IL-1β,IL-6,and TNF-α were significantly increased in the pyramidal cells of the CA1 region of the hippocam-pal tissue(P<0.05).In contrast,the escape latency was significantly reduced and the expression levels of GFAP,P2Y1R,IL-1β,IL-6,and TNF-α were significantly decreased in the DEACMP+MRS2179 group when compared with the DEACMP+DMSO group(P<0.05).Conclusion:P2Y1R activates astrocytes to release inflammatory factors lead-ing to the onset of cognitive impairment in DEACMP,and inhibition of P2Y1R reduces the expression of inflammatory factors and thus improves cognitive function in DEACMP.

Objective To investigate the relationship between the mean platelet volume(MPV)to platelet count(PLT)ratio(MPV/PLT),blood urea nitrogen(BUN)to lipoprotein a[Lp(a)]ratio[BUN/Lp(a)]and the prognosis of patients with acute exacerbation of chronic obstructive pulmonary disease(COPD).Methods A total of 106 patients with acute exacerbation of COPD admitted to the hospital from January 2021 to January 2024 were selected as the research objects.According to the prognosis,they were divided into sur-vival group(72 cases)and death group(34 cases).The results of routine laboratory tests,blood lipid and lipo-protein levels were compared between the two groups.Multivariate Logistic regression was used to analyze the influencing factors of death in patients with acute exacerbation of COPD.The receiver operating characteristic(ROC)curve was used to evaluate the predictive value of MPV/PLT and BUN/Lp(a)for the prognosis of pa-tients with acute exacerbation of COPD.Results Compared with the survival group,the invasive ventilation rate,acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)score,C reactive protein(CRP),white blood cell count(WBC),MPV,BUN,MPV/PLT and BUN/Lp(a)were significantly increased in the death group(P＜0.05).The non-invasive ventilation rate,lymphocyte count,PLT and Lp(a)levels were signifi-cantly decreased(P＜0.05).Multivariate Logistic regression analysis showed that APACHE Ⅱ score,CRP,WBC,lymphocyte count,MPV,PLT,MPV/PLT,BUN,Lp(a)and BUN/Lp(a)were the influencing factors of death in patients with acute exacerbation of COPD(P＜0.05).ROC curve results showed that the sensitivity and specificity of MPV/PLT combined with BUN/Lp(a)for predicting the prognosis of patients with acute exacerbation of COPD were 88.2％and 84.7％,respectively,and the area under curve was 0.887.Conclusion MPV/PLT and BUN/Lp(a)are closely related to the prognosis of patients with acute exacerbation of COPD.The combination of MPV/PLT and BUN/Lp(a)has a high predictive value for the prognosis of patients.

Objective:To clarify the changes of intrahepatic ultrasound hemodynamics before and after hepatic artery thrombosis (HAT) after liver transplantation (LT), providing early warning and anticoagulation guidance to clinicians.Methods:The clinical data of patients who underwent liver transplantation at Zhongshan Hospital of Fudan University between June 2006 and October 2022 were retrospectively analyzed, 47 patients with a diagnosis of HAT confirmed by DSA (digital subtraction angiography) were included in the HAT group, and 71 patients without vascular complications were included in the non-HAT group. Differences in peak flow velocity (PSV), resistance index (RI), and portal vein velocity (PVV) were compared between the two groups. Logistic regression analysis was used to determine the relationship between postoperative PSV decline and HAT occurrence, while ROC curve were used to determine the critical value and evaluate the diagnostic efficacy. Patients with HAT were divided into well-treatment group and poor-treatment group according to whether the blood flow was restored after multiple surgeries or thrombolytic treatments. The changes of early intrahepatic hemodynamics after surgical or thrombolytic therapy were compared between the two groups.Results:①A decrease in PSV of the transplanted hepatic artery was measured 1 d before HAT, and PSV<0.39 m/s predicted thrombus formation with a sensitivity of 0.70, specificity of 0.86, and the AUC was 0.83. ②After treatment, PSV in the HAT group increased immediately, approaching the normal level on the 2nd day. In the well-treatment group, PSV and PVV reached normal levels on the first day after treatment, which were significantly higher than the corresponding values in the poor-treatment group ( P=0.030, 0.021). Conclusions:In the early stage after liver transplantation, a PSV<0.39 m/s is related to the occurrence of HAT thrombosis 1 d later. A significant increase in PSV on the first day after treatment indicates a good treatment response, and there is no need for further DSA re-examination or increasing the number of thrombolysis.

This paper summarized Professor ZHANG Zhiwen's clinical experience in treating pulmonary nodules. Professor ZHANG proposed that the pathogenesis of pulmonary nodules is impairment of qi and body fluid distribution， sweating pores constraint and block， binding of phlegm and stasis， and long-term accumulation transforming into toxin， with abnormal circulation of qi， blood and body fluid as the root， and phlegm， stasis and toxin as the branch. According to the evolution of pathogenesis， a dynamic diagnosis and treatment idea of "regulating qi and body fluid， opening sweating pores， penetrating kenang （窠囊）， and preventing cancer toxins" is proposed， including the methods of regulating qi and body fluid， and calming the five zang （脏） organs with the modified self-prescribed Tiaoqi Huatan Decoction （调气化痰汤）， opening sweating pores and unblocking qi and blood with the modified self-prescribed Kaixuan Tongyu Decoction （开玄通郁汤）， penetrating kenang and dissipating masses and stagnation with the modified self-prescribed Tounang Sanjie Decoction （透囊散结汤）， rectifying the healthy qi and preventing cancer toxins with the modified self-prescribed Shenqi Fuzheng Jiedu Decoction （参芪扶正解毒汤）. These four methods can be used alone， in combination， or in sequence， and can provide ideas for the diagnosis and treatment of pulmonary nodules with traditional Chinese medicine.

Objective By employing surgically induced varicocele(VC)in SD rats and an apomorphine(APO)test,we screened rats with erectile dysfunction(ED)after VC and explored method to establish VC and ED models.Methods Sixty rats were randomly divided into Control,Sham,and Model groups with 20 rats in each group.Using the Turner method,we partially ligated the left renal vein to induce left VC three times.APO tests were conducted to screen rats with ED after inducing VC.The numbers of erections,genital grooming,and yawning were observed and recorded.The diameter of bilateral spermatic veins were measured.Both testises and kidneys were weighed.HE staining was used to observe pathological changes of penis and left testis.The success rate of modeling was calculated in the Model group.Results A VC and ED model was successfully established in 15 out of 20 rats in the Model group with a success rate of 75％.After modeling,the diameter of the left spermatic vein in the model group was increased significantly(P＜0.01)and was significantly larger than that before modeling(P＜0.01).The diameter of the right spermatic vein in the Model group was increased(P＜0.05)and higher(P＜0.05)than that before modeling.The weight of the left testis in the Model group was significantly decreased(P＜0.01)compared with that of the right testis.No significant difference in the bilateral kidney weights were observed between or within groups(P＜0.05).In the Model group,the numbers of erections,yawning,and genital grooming decreased significantly(P＜0.01)with the time of modeling.Pathological changes of the left testis and penis were significant in the Model group.Conclusions The Turner method increases the diameter of the spermatic vein in rats,causing testis injury and weight loss,and APO tests can be used to screen rats with ED after VC induction.The combination of the two method is suitable to establish an animal model of VC with an ED status similar to humans.

Objective To rapidly evaluate the efficacy,safety,and economics of dexmedetomidine in patients on mechanical ventilation in intensive care unit(ICU),and to provide references for clinical and decision makers.Methods To search PubMed,Embase,Cochrane Library,CNKI,WanFang Data databases and official websites of domestic and foreign Health Technology assessment(HTA)institutions from the inception to June 14,2023.HTA reports,systematic reviews/Meta-analyses,and pharmacoeconomic studies of patients with mechanical ventilation in ICU compared with dexmedetomidine versus placebo or other traditional sedatives were included.Two reviewers independently identified studies,extracted data,assessed the quality of included studies,and descriptive analyzed and summarised the results.Results A total of 13 literatures were included,including 10 systematic reviews/Meta-analyses and 3 economic studies.The analysis results of effectiveness showed that compared with placebo or other traditional sedatives,the use of dexmedetomidine in the sedation of mechanically ventilated patients in the ICU was associated with a shorter duration of mechanical ventilation and a shorter length of stay in the ICU.The analysis results of safety displayed treatment with dexmedetomidine could reduce the incidence of delirium,but may increase the incidence of bradycardia.The results of the economic analysis showed that the dexmedetomidine group had a higher cost of medication,but a lower overall ICU cost.Conclusion Dexmedetomidine has good efficacy,safety and economics in the sedation of patients on mechanical ventilation in ICU,but the economic studies included in the search were mainly foreign studies,and domestic economy studies needs to be further demonstrated.

Objective:To explore the feasibility and effect of remote medical education model using online film reading training to improve the ability of ophthalmologists in the Xinjiang Uygur Autonomous Region (hereinafter referred to as "Xinjiang Region" ) in diagnosing fundus diseases.Methods:The three-level film reading training system of Xinjiang Production and Construction Corps system division hospital-Corps Hospital-Peking Union Medical College Hospital was established. From June 2022 to January 2023, 4 159 posterior color fundus images were continuously collected from Department of Ophthalmology of Xinjiang Corps Hospital and 4 divisional hospitals in the Corps medical system. Among them, hypertensive retinopathy, diabetic retinopathy, exudative age-related macular degeneration (AMD), atrophic AMD and retinal vein occlusion were 3 073, 651, 43, 186 and 206 cases, respectively. The images were divided into 3 rounds (first, second and last) according to the proportion of diseases. The doctors who participated in the training (hereinafter referred to as the "training") were 15 ophthalmologists from the Corps Hospital of Xinjiang Region and the division hospital of the Corps system. There were 7 male and 8 female. Age was (38.1±4.0) years. The titles of senior, deputy senior, intermediate and junior are 1, 6, 5 and 3 respectively; Bachelor's degree and master's degree are 13 and 2 respectively. The working time of fundus disease specialty was (9.6±3.3) years. The film reading system training was conducted before the first round of labeling, and after each round of film reading, the doctors of Peking Union Medical College Hospital gave feedback and explanation on the film reading results. The diagnostic consistency, sensitivity and specificity were compared by paired sample t test. Spearman or Pearson correlation analysis was conducted between the improvement of diagnostic level and professional title, education, age and working hours of ocular fundus disease. Results:All the participating doctors completed the first, second and last reading. After each round of film reading, the film reading summary was carried out for 2 hours. The average diagnostic agreement rates of participating physicians were 53.0%, 67.0% and 75.0%, respectively. The sensitivity and specificity were 0.38, 0.69, 054 and 0.66, 0.85, 0.96, respectively. There was significant difference between the first and last examination ( P<0.001). The sensitivity of the second reading was significantly higher than that of the first reading, and the sensitivity of the last reading was significantly lower than that of the second reading, with statistical significance ( P<0.05). The specificity of the second reading was significantly higher than that of the first reading, and the last reading was significantly higher than that of the second reading, with statistical significance ( P<0.05). There was no significant correlation ( P>0.05) between the improvement of diagnostic level of participating physicians and educational background ( Rho=0.07), professional title ( Rho=0.13), age ( r=0.20), and working time of ophthalmofundus disease specialty ( r=0.26). Conclusions:Relying on the three-level online telemedicine training, it can improve the ability of ophthalmologists in Xinjiang region to diagnose fundus diseases. The preliminary telemedicine education model has demonstrated potential for feasibility and effectiveness in remote areas with inadequate medical resources.

Objective:To analyze the disease burden of Parkinson's disease (PD) in China from 1990 to 2021 and predict the disease burden of PD from 2022 to 2030.Methods:Based on the data of PD incidence in China from the Global Burden of Disease Study 2021 (GBD 2021), changes in PD disease burden from 1990 to 2021 were analyzed. Age-period-cohort model was used to analyze the independent influences of age, period and cohort in PD incidence (according to age group of 5 years, patients were divided into 15 groups: group of 20-24 years, group of 25-29 years..., and group of 90-94 years; according to a 5-year period, patients were divided into 6 groups: group of 1992-1996, group of 1997-2001..., and group of 2017-2021; because of birth cohort=period-age, patients were divided into 20 birth cohorts: birth cohort of 1897-1906, birth cohort of 1902-1911..., and birth cohort of 1992-2001). Nordpred model was used to predict the disease burden of PD from 2022 to 2030.Results:(1) From 1990 to 2021, number of PD patients, and PD incidence and standardized incidence in China showed upward trends. The standardized incidence increased by 89.68% for the total population, 89.71% for males, and 77.64% for females. (2) PD incidence was low in young subjects and increased obviously in subjects aged 60 years. PD incidence in subjects aged 20-24 years or 90-94 years was 0.07/100 000 and 643.31/100 000, respectively. Compared with female subjects, male subjects aged 60-94 years had higher PD incidence. (3) The onset relative risk increased from 0.71 (95% CI: 0.69-0.73) in group of 1992-1996 to 1.17 (95% CI: 1.16-1.19) in group of 2017-2021 in the total population, increased from 0.68 (95% CI: 0.66-0.70) to 1.18 (95% CI: 1.16-1.21) in males, and increased from 0.75 (95% CI: 0.73-0.77) to 1.14 (95% CI: 1.12-1.16) in females. (4) Onset relative risk was 0.40 (95% CI: 0.33-0.48) in the earliest birth cohort (1897-1906), which increased to 1.81 (95% CI: 0.95-3.43) in the latest birth cohort (1992-2001). (5) Number of PD patients in males, females and total population in China would increase to 455 010, 301 173 and 756 183, respectively, and the standardized incidence would increase to 56.45/100 000, 32.28/100 000 and 43.40/100 000, respectively, till 2030. Conclusion:PD disease burden in China from 1990 to 2021 is severe, particularly among males and the elderly; the disease burden is projected to continue rising up till 2030.
