Guided by Academician Zhang Boli's theory of "dampness， turbidity， phlegm， and fluid-related diseases"，this paper elaborated on the pathogenesis and syndrome differentiation treatment of heart failure from the perspective of the "spleen-mitochondria". It analyzed the essential similarities between "spleen-mitochondria" and "dampness， turbidity， phlegm， and fluid-related diseases"， as well as their close association with the onset of heart failure. Furthermore，it explored the connection between spleen function and mitochondrial function in traditional Chinese medicine （TCM），positing that the spleen's role in transportation and transformation is analogous to mitochondrial material metabolism and energy conversion，with spleen deficiency closely related to mitochondrial dysfunction. It thus concluded that mitochondrial material metabolism and energy conversion represent the microscopic essence of the spleen's role in transportation and transformation，and mitochondrial dysfunction is a contributing factor to pathological products like dampness and turbid phlegm，which are closely associated with the occurrence of heart failure. The four elements of dampness，turbidity，phlegm，and fluid are a series of related symptoms resulting from abnormal fluid transportation and transformation，serving as both factors in the onset of heart failure and the core pathological basis for its deterioration. Therefore，during the treatment of heart failure，it is essential to regulate mitochondrial function. Early intervention should focus on eliminating dampness and turbidity to improve mitochondrial function and restore normal energy metabolism. In the middle and late stages，emphasis should be placed on resolving phlegm，promoting blood circulation，warming Yang，and reducing water retention to alleviate mitochondrial damage and improve cardiac function. Supporting Qi and strengthening the spleen should be a continuous approach，and treatment should be adjusted to enhance mitochondrial function and stabilize the condition，thereby improving prognosis. This paper discussed the role of the spleen and mitochondria in the pathogenesis of heart failure，examined the evolution of heart failure mechanisms from the perspective of dampness， turbidity， phlegm， and fluid-related diseases，and proposed a phased treatment strategy. It enriched the theory of dampness， turbidity， phlegm， and fluid-related diseases and offered new strategies for heart failure treatment. However，in practical application，TCM strategies for treating heart failure need to be integrated with modern medical approaches to provide a more solid scientific foundation for treatment.

ObjectiveTo understand the status of parasitic infection in the food sold on market in Qingpu District of Shanghai, and to provide an evidence for the development of prevention and control strategies for parasitic infection applicable to Qingpu District. MethodsAquatic products, meat products and other foodstuffs sold on online shops, at farm product markets, supermarkets/foodstores and restaurants were sampled in Qingpu District, Shanghai, during 2015‒2023, based on the administrative division of Qingpu District. The parasitic infection in the food samples were examined using pressing method and digestion for detecting metacercariae in freshwater products and pickled products, using dissection microscopy for Anisakis larvae in seawater products, Taenia cysticercus and Trichinella encysted larvae in meat products. ResultsA total of 1 079 samples of food products were examined during 2015‒2023, with a total parasite infection rate of 13.44%. The total parasite infection rate of freshwater fish products was 3.40% (16/471), and the difference of parasite infection rates between different freshwater fish species was statistically significant (χ²=229.609, P=0.001). The total infection rate of Clonorchis sinensis was 3.18% (15/471), which had been detected in Pseudorasbora parva, Cyprinidae rhodeus, and Carassius auratus, with a positive rate of 77.78% (7/9), 50.00% (5/10) and 3.90% (3/77), respectively. Metorchis orientalis was detected in in Pseudorasbora parva, with a positive rate of 33.33% (3/9). The positive rate of Gnathostoma spinigerum (third-stage larvae) was 0.81%. Paragonimus metacercariae were not detected in the freshwater shrimps and crabs. The infection rate of seawater fish products was 26.46%. The difference of parasite infection rate in seawater fishes was statistically significant (χ²=109.181, P=0.001). A total of 53 pork and beef samples were tested, none was detected with Trichinella larva cysts, Taenia solium metacercariae, and Taenia saginata metacercariae. The total infection rate of pickled yellow mud snail products was 58.11% (43/74). Paragonimus metacercariae was not detected in any of the pickled aquatic product samples. ConclusionThere are different degrees of parasitic infection in freshwater products, seawater products and pickled aquatic products in Qingpu District of Shanghai. The risk of parasite infection from raw or undercooked foods is high. Health education on healthy dietary practices such as throughly cooked food should be strengthened for local residents.

ObjectiveTo investigate the effects of Scutellariae Radix combined with epidermal growth factor receptor-tyrosine kinase inhibitors （EGFR-TKIs） on cell proliferation， apoptosis， cancer stem cell （CSC） marker expression， and metabolism in non-small cell lung cancer （NSCLC） cells. MethodsThe anti-tumor effects of Scutellariae Radix and EGFR-TKIs （gefitinib or osimertinib） in NSCLC cells were evaluated using the cell counting kit-8 （CCK-8） and Annexin V-FITC/propidium iodide （PI） double staining apoptosis assay. The activity of Scutellariae Radix and EGFR-TKIs in three-dimensional （3D） cultures of NSCLC cells was assessed using the CellTiter-Glo® 3D cell viability assay. The mRNA and protein expression levels of CSC markers， sex determining region y box protein 2 （SOX2） and aldehyde dehydrogenase 1 family member A1 （ALDH1A1）， were detected by quantitative real-time polymerase chain reaction （Real-time PCR） and Western blot， respectively. Changes in intracellular reactive oxygen species （ROS） levels were detected by ROS staining， and the redox ratio was detected by femtosecond laser labeling free imaging （FLI）. ResultsUnder both two-dimensional （2D） and 3D culture conditions， compared with the blank group and EGFR-TKI group， the combination group showed significantly reduced cell viability and increased apoptosis rate （P<0.05）. Compared with the EGFR-TKI group， the mRNA and protein levels of CSC markers were significantly downregulated in the combination group （P<0.05）. Additionally， the redox ratio was significantly elevated （P<0.05）， and ROS levels were also increased in the combination group compared with the EGFR-TKI group. ConclusionIn NSCLC cells， Scutellariae Radix enhances the redox ratio and increases ROS levels， thereby inhibiting the expression of CSC markers and strengthening the anti-tumor effects of EGFR-TKIs. This provides a novel molecular mechanism by which Scutellariae Radix may enhance the sensitivity of targeted therapies.

The biological clock(also known as the circadian rhythm)is the fundamental reliance for all organisms on Earth to adapt and survive in the Earth's rotation environment.Circadian rhythm is the most basic regulatory mechanism of life activities,and plays a key role in maintaining normal physiological and biochemical homeostasis,disease occurrence and treatment.Recent studies have shown that the biologi-cal clock plays an important role in the development of oral tissues and in the occurrence and treatment of oral diseases.Since there is cur-rently no guiding literature on the research methods of biological clock in stomatology,researchers mainly conduct research based on pub-lished references,which has led to controversy about the research methods of biological clock in stomatology,and there are many confusions about how to rationally apply the research methods of circadia rhythms.In view of this,this expert consensus summarizes the characteristics of the biological clock and analyzes the shortcomings of the current biological clock research in stomatology,and organizes relevant experts to summarize and recommend 10 principles as a reference for the rational implementation of the biological clock in stomatology research.

ObjectiveTo compare and observe the effect of Reduning injection （mainly clearing heat）， Shenfu injection （mainly warming Yang） combined with gefitinib on the proliferation， apoptosis， stemness characteristics and metabolism of lung cancer cells. MethodDifferent non-small cell lung cancer （NSCLC） cell lines were selected and intervened with gefitinib （5， 10， 20 μmol·L^-1）， Reduning injection （0.6%， 0.9%）， Shenfu injection （0.6%， 0.9%）， gefitinib combined with Reduning injection， and gefitinib combined with Shenfu injection. Cell proliferation in each group was detected by cell counting kit-8 （CCK-8） assay， and cell apoptosis was detected by flow cytometry. The mRNA and protein expressions of lung cancer stem cell markers sex determining region Y-box 2 （Sox2） and aldehyde dehydrogenase family 1 member A1 （ALDH1A1） were determind by real-time quantitative polymerase chain reaction （Real-time PCR） and Western blot， respectively. The redox ratio of lung cancer cells was observed by femtosecond label-free imaging （FLI） and energy metabolism instrument was used to determine the glycolysis level in cells. ResultCompared with the blank group， Reduning injection reduced the survival rate of lung cancer cells （P<0.05）， increased the apoptosis rate （P<0.05）， down-regulated the mRNA and protein expressions of Sox2 and ALDH1A1 （P<0.05）， and up-regulated the redox ratio of cells （P<0.05）， while Shenfu injection exerted no remarkable effect on the above indexes. In addition， compared with gefitinib alone， Reduning injection combined with gefitinib inhibited the survival rate of lung cancer cells （P<0.05）， promoted the cell apoptosis （P<0.05）， down-regulated the mRNA and protein expressions of Sox2 and ALDH1A1 （P<0.05）， up-regulated the redox ratio of cells （P<0.05）， and lowered the proton efflux rate of glycolysis （P<0.05）， while Shenfu injection combined with gefitinib failed to affect these indexes of lung cancer cells significantly. ConclusionReduning injection may inhibit stemness characteristics of tumor cells by regulating their metabolism to enhance the proliferation-inhibiting and pro-apoptotic effects of gefitinib on lung cancer cells， while Shenfu injection had no significant enhancing effect on gefitinib. This indicates that epidermal growth factor receptor tyrosine kinase inhibitors （EGFR-TKIs） should be used in combination with heat-clearing Chinese medicines.

Strengthening the standard formulation and quality management of traditional Chinese medicine（TCM） dispensing granules is an important part of the strategic planning for the development of TCM in China. In order to examine the clinical application and overall quality control of the existing national standards for TCM dispensing granules， this study classified and summarized the varieties in the existing standards， analyzed their clinical applicability， and discussed the characteristics of the test methods for identification， content determination and specific chromatogram/fingerprint. It was found that the coverage of the existing standards was inadequate in terms of quantity， and it was even weaker in the aspects of therapeutic efficacy， herb family， processing method and preparation method of TCM dispensing granules. It was concluded that the characteristics of national standards in test methods were summarized as follows：guided by clinical application， based on the reference system， taking specific chromatogram as a breakthrough， so as to improve the overall quality control of TCM dispensing granules. It is suggested that the coverage of national standards should be subsequently expanded to meet the needs of market development. In order to enhance clinical applicability， the content of national quality standards should be increased， including increasing variety diversity to meet the needs of clinical application， raising the standard requirements to improve the clinical medication experience， and strengthening effectiveness research to highlight clinical efficacy. At the same time， the accessibility of regulatory inspection is enhanced， the rules for the management of varieties without national standards are promulgated to lay the foundation for the healthy and orderly development of TCM dispening granule industry.

Objective To investigate the correlation between left ventricular dysfunction and cogni-tive impairment in patients with ischemic heart disease(IHD),and explore the potential patho-genesis of cognitive impairment in IHD patients.Methods Fifty IHD patients who underwent hybrid cardiac PET/MR in our hospital from September 2020 to December 2022 were retrospec-tively enrolled in this study.According to their Montreal cognitive assessment(MoCA)scores,they were categorized into a cognitively normal group(21 cases,MoCA score ≥26)and a cogni-tively declining group(29 cases,MoCA score＜26).All patients received 13N-NH3·H2O myocar-dial perfusion imaging and 18F-FDG cardiac PET/MR to evaluate cardiac function and obtain car-diac imaging parameters.Spearman correlation analysis was applied to analyze the correlation between cardiac PET/MR parameters and MoCA scores.General linear model analysis was applied to analyze the correlation between MoCA scores and cardiac PET/MR parameters after adjusting for co variates.Results Compared with the cognitively normal group,the patients in the cognitively declining group had significantly lower stroke volume[56.95(47.51,77.64)ml vs 82.66(73.88,92.92)ml,P=0.001],stroke volume index[34.07(28.93,43.20)ml/m2 vs 44.28(38.06,49.49)ml/m2,P=0.008],cardiac output[3.92(3.18,5.34)L/min vs 5.13(4.58,5.67)L/min,P=0.007],and cardiac index[(2.42±0.68)L/(min·m2)vs(2.78±0.39)L/(min·m2),P=0.021].Spearman correlation analysis revealed that MoCA score was positively correlated with stroke volume(r=0.497,P=0.001),stroke volume index(r=0.365,P=0.009)and cardiac output(r=0.361,P=0.010).After adjusting for sex,age,education level and vascular risk factors,MoCA score re-mained positively correlated with stroke volume(r=0.497,P=0.003).Conclusion Systemic hy-poperfusion in IHD patients may be one of the mechanisms leading to cognitive impairment.
