Under the background of the Healthy China strategy， the integration of traditional Chinese medicine （TCM） into the public health emergency response system has become an important measure to enhance the capacity for coping with public health emergencies. In recent years， the role of TCM in responding to such emergencies has become increasingly prominent. Taking major emerging epidemics as an example， TCM has developed a rich theoretical system and practical experience in epidemic prevention and treatment over thousands of years， and has played a significant role in successive outbreaks with its unique advantages. Based on the concept of ''preventing disease before its onset'' and the theoretical framework of treatment based on syndrome differentiation， TCM has achieved remarkable results through early intervention and full participation in the integrated model of TCM and Western medicine， from severe acute respiratory syndrome （SARS） to corona virus disease-2019 （COVID-19）， in improving clinical symptoms and outcomes， reducing adverse reactions， and promoting recovery. From the perspective of the Healthy China strategy， this paper systematically reviews the historical development of TCM in epidemic prevention and treatment， with particular attention to recent epidemics such as SARS， influenza A （H1N1）， and COVID-19. It further examines the similarities and differences between TCM and Western medicine in responding to major emerging epidemics， as well as relevant policies related to TCM in epidemic prevention and control. In addition， it summarizes the existing problems in TCM's role in the prevention and treatment of major emerging epidemics， and explores measures to improve its rapid response capacity under the Healthy China strategy. This study not only provides a ''Chinese solution'' for the prevention and control of newly emerging infectious diseases worldwide， but also offers theoretical and practical references for strengthening the public health emergency response system， carrying strategic significance for promoting the modernization and internationalization of TCM.

Objectives:To explore the burden and trend of cardiovascular diseases(CVD)attributed to household air pollution(HAP)in the world and China from 1990 to 2019. Methods:Based on the Global Burden of Disease(GDB)database in 2019,the CVD data attributed to HAP in China and around the world were extracted,and the mortality and disability-adjusted life years(DALY)and their age standardized rate(ASR)and estimated annual percentage change(EAPC)were used to analyze the burden of disease and trend in China and other regions and countries from 1990 to 2019. Results:From 1990 to 2019,the age-standardized death rate(ASDR)(EAPC=-3.65,95%CI:-3.86 to-3.44),and the age-standardized DALY rate(EAPC=-3.60,95%CI:-3.78 to-3.41)attributable to HAP for CVD globally showed a decreasing trend.In China,the ASDR(EAPC=-5.78,95%CI:-6.17 to-5.38)and the age-standardized DALY rate(EAPC=-5.97,95%CI:-6.32 to-5.62)also showed a declining trend.The burden of males was slightly higher than females,reaching its peak at the age of 75 to 89 years.The largest increase of the burden of CVD attributed to HAP was in Philippines(ASDR:EAPC[95%CI]=0.87[0.21-1.54];age-standardized DALY rate:EAPC[95%CI]=1.32[0.60-2.03]),and the largest decline was in Saudi Arabia(ASDR:EAPC[95%CI]=-18.48[-18.63 to-18.32];age-standardized DALY rate:EAPC[95%CI]=-18.25[-18.38 to-18.12]).In 2019,the highest disease burden of CVD related to HAP per 100 000 people was significantly higher in ASDR(56.67,95%UI:42.08-73.07)and age-standardized DALY rate(1 318.63,95%UI:997.40-1 672.29)in areas with low social demographic index(SDI)than in other SDI areas.In 2019,among the 21 geographical regions and 204 countries in the world,the highest disease burden per 100 000 people was in Oceania,and the highest country was Solomon Islands,the corresponding ASDR of China was 12.52(95%UI:6.35-21.29)and the age-standardized DALY rate was 262.65(95%UI:133.90-447.50). Conclusions:From 1990 to 2019,the age-standardized burden of CVD attributable to HAP in the world and China showed a consistent downward trend,with males slightly higher than females,and the burden concentrated on population between 75 and 89 years old.Although there has been a certain decline in China,the disease burden is still high,so there is still a urgent need to take strong intervention measures to reduce burden of CVD attributable to HAP in China.

Objective To investigate the effect of galectin-1 preconditioning on pyroptosis of venti-lator-induced lung injury(VILI)in mice.Methods Thirty clean grade healthy male C57BL/6 mice,aged 6-8 weeks,weighing 22-30 g,were divided into three groups by random number table method:control group(group C),VILI group(group V),and galectin-1+VILI group(group G),10 mice in each group.After endotracheal intubation,group C kept spontaneous breathing for 4 hours,groups V and G kept me-chanical ventilation for 4 hours.One hour before endotracheal intubation,groups C and V were intraperito-neally injected with normal saline 0.75 ml,and group G was intraperitoneally injected with galectin-1 3 μg.Arterial blood was collected before endotracheal intubation and after spontaneous respiration or ventilation to detect PaO2.Then mice were sacrificed and bronchoalveolar lavage fluid(BALF)was collected.Concentra-tions of IL-1β and IL-18 in BALF were detected by ELISA.Lung tissue was collected for determination of the wet weight/dry weight ratio(W/D).The expression of GSDMD,caspase-1,and caspase-11 mRNA and protein in lung tissues were detected by qRT-PCR and Western blot.Pathological changes of the lungs were observed and scored by HE staining.Results Compared with group C,PaO2 were significantly decreased,W/D,concentrations of IL-1β and IL-18 in BALF,mRNA and protein expressions of GSDMD,caspase-1 and caspase-11,and lung injury score were significantly increased in groups V and G(P＜0.05).Com-pared with group V,PaO2 was significantly increased,W/D,concentrations of IL-1β and IL-18 in BALF,mRNA and protein expressions of GSDMD,caspase-1,and caspase-11,and lung injury score were signifi-cantly decreased in group G(P＜0.05).Conclusion Galectin-1 can increase PaO2 in mice and reduce IL-1β and IL-18 concentration,mRNA expression and protein content of classical non-classical pyroptosis pathway related genes,and reduce VILI in mice.

Objective:To explore the influencing factors of continuous renal replacement therapy(CRRT)after heart transplantation(HT).Methods:For this retrospective cohort study, the relevant clinical data were retrospectively reviewed for 145 recipients undergoing HT at No.7 Municipal People's Hospital from April 2018 to December 2022.They were assigned into two groups of non-CRRT(n=124)and CRRT(n=21). And t, χ2or rank-sum test was utilized for comparing baseline data, intraoperative and postoperative general conditions of two groups.Variables with P<0.05 in univariate analysis and significant indicators in previous studies were included in multivariate logistic regression analysis to analyze the influencing factors of CRRT post-HT.Receiver operating characteristic curve(ROC)was utilized for selecting the optimal predictive cut-off value. Results:Among them, 66 cases(45.52%)developed AKI and 21(14.48%)required CRRT.Through univariate analysis, preoperative estimated glomerular filtration rate(eGFR), erythrocyte count, platelet, hemoglobin, total bilirubin, intraoperative volume of blood loss, volume of blood transfusion, urine volume, operative duration, cardiopulmonary bypass time, postoperative mechanical ventilation time, ICU stay and postoperative acute kidney injury were compared.The inter-group differences were statistically significant( P<0.05). Further multivariate logistic regression analysis revealed that preoperative hemoglobin level( OR=0.869, 95% CI: 0.770-0.980, P=0.022), preoperative platelet count( OR=0.959, 95% CI: 0.925-0.993, P=0.019), intraoperative volume of hemorrhage( OR=1.004, 95% CI: 1.000-1.009, P=0.049), intraoperative urine volume( OR=0.997, 95% CI: 0.993-1.000, P=0.035), operative duration( OR=1.022, 95% CI: 1.000-1.044, P=0.047)and mechanical ventilation time( OR=1.036, 95% CI: 1.005-1.069, P=0.024)were the independent influencing factors of CRRT post-HT.ROC curve results indicated that area under curve(AUC)of operative duration, mechanical ventilation time and intraoperative volume of hemorrhage were 0.745(95% CI: 0.636-0.855), 0.835(95% CI: 0.735-0.934)and 0.669(95% CI: 0.506-0.830)with a sensitivity of 0.714, 0.857, 0.571 and a specificity of 0.710, 0.685, 0.895.And the cut-off values were 283.5 min, 25.46 h and 825 ml respectively. Conclusions:Hemoglobin level, preoperative platelet count, intraoperative volume of hemorrhage, urine volume, operative duration, mechanical ventilation time and intraoperative urine volume are independent influencing factors of CRRT post-HT.Operative duration >283 min, mechanical ventilation time >25.46 h and intraoperative volume of hemorrhage >825 ml have some predictive values for CRRT post-HT.

Objective:To evaluate the effect of irisin on the alveolar macrophage polarization in a rat model of ventilator-induced lung injury (VILI).Methods:Thirty SPF healthy adult male Sprague-Dawley rats, aged 6-8 weeks, weighing 200-250 g, were divided into 3 groups ( n=10 each) using a random number table method: control group (group C), VILI group (group V) and irisin group (group I). The rats were mechanically ventilation (tidal volume 20 ml/kg, respiratory rate 80 times/min, inhaled oxygen concentration 21%, inspiratory/expiratory ratio 1∶2, positive end-expiratory pressure 0) for 4 h to develop VILI model.Group C kept spontaneous breathing for 4 h. Irisin 1 μg/kg was injected via the tail vein at 30 min before tracheal intubation in group I, while the equal volume of normal saline was given instead in the other groups.The rats were sacrificed at 4 h of mechanical ventilation, the lung tissues were removed for examination of pathological changes which were scored and for determination of wet to dry weight ratio (W/D ratio), and bronchoalveolar lavage fluid (BALF) was collected for determination of concentrations of interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α) and IL-10 (by enzyme-linked immunosorbent assay), expression of inducible nitric oxide synthase (iNOS), argininase 1 (Arg-1), and phosphorylated nuclear factor kappa B (p-NF-κB) p65 and p-NF-κB p50 in alveolar macrophages (by Western blot), and percentage of M1 and M2 alveolar macrophages and M1/M2 ratio (by flow cytometry). Results:Compared with group C, the W/D ratio, lung injury score, and concentrations of IL-6, TNF-α and IL-10 in BALF were significantly increased, the expression of iNOS, Arg-1, p-NF-κB p65 and p-NF-κB p50 was up-regulated, and the percentage of M1 and M2 alveolar macrophages and M1/M2 ratio were increased in group V and group I ( P<0.05). Compared with group V, the W/D ratio, lung injury score, and concentrations of IL-6 and TNF-α in BALF were significantly decreased, the expression of iNOS and p-NF-κB p65 was down-regulated, the percentage of M1 alveolar macrophages and M1/M2 ratio were decreased ( P<0.05), and no significant change was found in levels of IL-10 and Arg-1 in BALF, percentage of M2 alveolar macrophages and expression of p-NF-κB p50 in group I ( P>0.05). Conclusions:The mechanism by which irisin reduces VILI may be related to inhibition of NF-κB signaling pathway activation and reduction of alveolar macrophage polarization to M1 phenotype in rats.

There was no significant difference in the conversion to open surgery between the two groups ( P>0.05). Five patients of the robotic group and 7 patients of the laparoscopic group had postoperative complications. There was no significant difference in the postoperative complications between the two groups ( χ2=0.405, P>0.05). (3) Postoperative pathological examination: after propensity score matching, cases with R 0 resection, the number of lymph node dissected, cases with lymph node metastasis and cases with tumor differentiation as well differentiated adenocarcinoma, moderately differentiated adeno-carcinoma, poorly differentiated adenocarcinoma or mucinous adenocarcinoma were 34, 17±5, 14, 1, 22, 6, 5 of the robotic group, versus 34, 17±5, 12, 2,20, 2, 10 of the laparoscopic group, respectively. There was no significant difference in the R 0 resection between the two groups ( P>0.05) and there was no significant difference in the number of lymph node dissected, lymph node metastasis and tumor differentiation between the two groups ( t=0.488, χ2=0.249, 4.095, P>0.05). (4) Follow-up: after propensity score matching, 68 patients were followed up for 1?36 months, with a median follow-up time of 24 months. The follow-up time was (20±13)months of the robotic group, versus (21±13)months of the laparoscopic group, showing no significant difference between the two groups ( t=0.409, P>0.05). During the follow-up, 3 cases of the robotic group and 4 cases of the laparoscopic group had tumor distant metastasis. The disease-free survival rate and overall survival rate at postoperative 3 years were 83.9% and 86.8% of the robotic group, versus 82.0% and 86.6% of the laparoscopic group, showing no significant difference between the two groups ( χ2=0.188, 0.193, P>0.05). Conclusion:Da Vinci robotic assisted CME for right hemicolon cancer is safe and feasible.

Objective:To evaluate the effect of irisin on ventilator-induced lung injury (VILI) in rats and the relationship with expression of NOD-like receptor pyrin domain containing 3 (NLRP3) inflammasomes.Methods:Thirty-six SPF-grade healthy adult male Sprague-Dawley rats, aged 6-8 weeks, weighing 220-300 g, were divided into 3 groups ( n=12 each) using a random number table method: control group (group C), group VILI and irisin group (group I). All the groups underwent tracheotomy and intubation, group C kept spontaneous breathing for 4 h, and the animals were mechanically ventilated for 4 h in VILI and I groups.Irisin 1 μg/kg was injected via the tail vein at 30 min before tracheal intubation in group I, and the equal volume of normal saline mixture (normal saline∶phosphate buffer solution containing 5% trehalose=1∶9) were given in the other 2 groups via the tail vein.The rats were mechanically ventilated with the tidal volume of 20 ml/kg, respiratory rate 80 breaths/min, inspiratory/expiratory ratio 1∶1, inspired oxygen fraction ratio 21% and positive end-expiratory pressure 0.Blood samples from left femoral artery were collected before tracheal intubation and at the end of mechanical ventilation for detection of PaO 2.The animals were sacrificed and the lung tissue samples and bronchoalveolar lavage fluid (BALF) were then collected for examination of the pathological changes (under the light microscope), and for determination of wet to dry weight (W/D) ratio and the concentrations of total protein in BALF and interleukin-1β (IL-1β) and IL-18 in BALF and serum (by enzyme-linked immunosorbent assay), level of reactive oxygen species (ROS) in alveolar macrophages in BALF (by DCFH-DA) and the expression of NLRP3, apoptosis-associated speck-like protein (ASC) and caspase-1 protein and mRNA in lung tissues (by Western blot and by quantitative reverse transcription polymerase chain reaction). The pathological changes of the lung were scored. Results:Compared with group C, PaO 2 was significantly decreased at the end of mechanical ventilation, lung injury score and W/D ratio were increased, concentration of total protein and ROS level in alveolar macrophages in BALF and concentrations of BALF, IL-1β and IL-18 in serum were increased, and the expression of NLRP3, ASC and caspase-1 protein and mRNA in lung tissues was up-regulated in group VILI and group I ( P<0.01). Compared with group VILI, PaO 2 was significantly increased at the end of mechanical ventilation, lung injury score and W/D ratio were decreased, concentration of total protein and ROS level in alveolar macrophages in BALF and concentrations of BALF, IL-1β and IL-18 in serum were decreased, and the expression of NLRP3, ASC and caspase-1 protein and mRNA in lung tissues was down-regulated in group I ( P<0.05). Conclusion:Irisin can reduce VILI, and the mechanism is related to inhibiting activation of NLRP3 inflammasome and reducing inflammatory response in rats.

Objective:To investigate the effect of irisin on pyroptosis in rats with ventilator-induced lung injury.Methods:Thirty-six healthy clean-grade male Sprague-Dawley rats, weighing 200-250 g, aged 6-8 weeks, were divided into 3 groups ( n=12 each) using a random number table method: control group (group C), ventilator-induced lung injury group (group V) and ventilator-induced lung injury plus irisin group (group V+ I). In group V+ I, irisin 1 μg/kg was injected via the tail vein before mechanical ventilation.The animals were mechanically ventilated (tidal volume of 40 ml/kg, respiratory rate 60 breaths/min, inspiratory/expiratory ratio 1∶2, positive end expiratory pressure 0 and inspired oxygen fraction ratio 21%.Blood samples were then taken from the femoral artery for blood gas analysis, and PaO 2 was recorded.Bronchoalveolar lavage fluid (BALF) was collected, the total protein concentrations in BALF were measured, and the concentrations of BALF and serum interleukin-1β (IL-1β) and IL-18 were measure by enzyme-linked immunosorbent assay.The lung tissues were obtained for determination of the pathological changes after HE staining which were scored, wet to dry weight (W/D) ratio, expression of pyroptosis-related proteins N-terminal gasdermin D (GSDMD-N) and caspase-1 protein and mRNA (by Western blot or using real-time polymerase chain reaction). Results:Compared with group C, the lung injury score and W/D ratio were significantly increased, PaO 2 and OI were decreased, the total protein concentrations in BALF, concentrations of IL-1β and IL-18 in BALF and serum were increased, and the expression of caspase-1 and GSDMD-N protein and mRNA was up-regulated in group V ( P<0.01). Compared with group V, the lung injury score and W/D ratio were significantly decreased, PaO 2 and OI were increased, the total protein concentrations in BALF, concentrations of serum IL-1β and IL-18 in BALF and serum were decreased, and the expression of caspase-1 and GSDMD-N protein and mRNA was down-regulated in group V+ I ( P<0.01). Conclusion:The mechanism by which irisin reduces ventilator-induced lung injury is probably related to inhibiting pyroptosis in rats.
