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.

Venous malformation is a common congenital, non-tumor vascular malformation, accounting for about 60% of all vascular malformations, of which 40% occur in the head and neck. Due to the complex anatomical structure of the oral and maxillofacial region and the diverse classification of venous malformations, their clinical treatment poses certain difficulties and challenges. This article systematically elaborates on the etiology, clinical manifestations, imaging features, and clinical treatment strategies of venous malformations in the oral and maxillofacial region. Molecular genetic studies have shown that the occurrence and development of venous malformations are closely related to abnormal activation of the ANGPT/TIE2/PI3K/AKT/mTOR signaling pathway; its clinical manifestations are gradually growing blue purple masses and its histological features are tortuous venous ducts; and clinical imaging examinations have high specificity, among which digital subtraction angiography classification has important clinical guidance value for the treatment of venous malformation sclerosis. According to different classifications, strategies, such as sclerosis treatment, surgical treatment, and laser treatment, can be applied separately or in combination. This article also explores the advantages and disadvantages of targeted therapy in the treatment of venous malformations, with a focus on improving clinical outcomes while reducing complications. At the same time, through the analysis of typical clinical cases, it summarizes the key points of diagnosis and treatment and treatment plans, in order to provide a reference for improving the clinical efficacy of venous malformation treatment and reducing treatment complications.

Lung cancer, particularly non-small cell lung cancer (NSCLC), is a leading cause of cancer-related mortality worldwide. In recent years, metabolomics has emerged as a key systems biology approach for analyzing small-molecule metabolites in cells, tissues and organisms. It provides new strategies for early diagnosis and metabolic profiling. Additionally, metabolomics plays a crucial role in studying resistance mechanisms in lung cancer. Tumor cell metabolic reprogramming is a key driving factor in the initiation and progression of lung cancer. Metabolomics studies have revealed how lung cancer cells regulate critical pathways such as energy metabolism, lipid metabolism, and amino acid metabolism to adapt to the demands of rapid proliferation and invasive metastasis. This review summarizes the latest advances in metabolomics research in lung cancer, focusing on the characteristics of metabolic reprogramming, the identification of potential metabolic biomarkers, and the prospects of metabolomics in early diagnosis and the elucidation of resistance mechanisms in lung cancer.

Objective To evaluate the correlation between 3D morphological parameters of aneurysms based on the computer-assisted semi-automated measurement and the risk of aneurysm rupture.Methods From October 2019 to October 2022,patients with ruptured multiple aneurysms admitted to the Department of Neurosurgery of Xuanwu Hospital,Capital Medical University were retrospectively included.Aneurysmal morphological parameters(including aneurysmal diameter,maximum diameter,width,neck width,volume,flow angle,parental artery diameter,surface area,wave index and non-spherical index)were measured by computer-assisted semi-automated measurement methods.The length-to-width ratio,wide-to-neck ratio,aspect ratio and size ratio were calculated,and the aneurysm location information was recorded.The ruptured aneurysms in multiple aneurysms were included in the ruptured group,and the remaining aneurysms were included in the unruptured group.Uni variable analysis and binary Logistic analysis were used to evaluate the differences in morphological parameters and location information between the ruptured and unruptured groups.Results All 56 patients with multiple ruptured aneurysms and a total of 126aneurysms were included in the group for analysis.Concerning morphology,including diameter＞5 mm(51.8％[29/56]vs.15.7％[11/70],P＜0.01),maximum diameter＞6mm(57.1％[32/56]vs.25.7％[18/70],P＜0.01),flow angle＞107°(57.1％[32/56]vs.35.7％[25/70],P=0.016),wide-to-neck ratio＞1.1(50.0％[28/56]vs.30.0％[21/70],P=0.022),aspect ratio＞1.1(46.4％[26/56]vs.25.7％[18/70],P=0.015)and size ratio＞1.9(57.1％[32/56]vs.10.0％[7/70],P＜0.01),there was significant difference between the ruptured and unruptured group;Concerning locations,aneurysms are mainly located in the posterior communicating segment of the internal carotid artery(39.3％[22/56])and the middle cerebral artery(23.2％[13/56])in ruptured group,while in the middle cerebral artery(28.6％[20/70])and the non-posterior communicating segment of internal carotid artery(27.1％[19/70])in unruptured group,and there was significant difference in distribution of aneurysm locations(P=0.003).Multivariate Logistic regression analysis showed that size ratio＞1.9 was an independent risk factor for aneurysm rupture(OR,11.62,95％CI 2.40-56.15;P=0.002).Concerning locations,posterior communicating artery aneurysms had a significantly higher risk of rupture compared with the non-posterior communicating segment of internal carotid artery(OR,19.25,95％CI 2.19-169.51;P=0.008).Conclusion For multiple intracranial aneurysms,the size ratio of the three-dimensional morphological parameters of aneurysms＞1.9 is an independent risk factor for aneurysm rupture,and the rupture risk of posterior communicating artery aneurysms is significantly higher than that of non-posterior communicating segment of internal carotid artery.

This article introduced the clinical experience of national famous TCM doctor Professor Xu Xin in the treatment of blood withered menstrual closure combined with obstruction in the abdomen.Professor Xu Xin believes that premature ovarian failure belongs to the category of blood withered menstrual closure in TCM,the etiology of which can be seen in essence and blood depletion and emotional anomalies;the mechanism of the disease is closely related to the dysfunction of visceral organs,and the source of qi and blood is not available,and the lack of essence and blood of the Chong Ren cystic uterus.Therefore,the treatment should be based on the basic rules of tonifying essence,qi and blood,adjusting the viscera and organs,and promoting blood circulation,and regulating menstruation.If combined with the obstruction in the abdomen,the patients'syndrome of blood stasis will be highlighted,and it is necessary to pay attention to the choice of drugs for removing blood stasis at the same time of applying the basic treatment,so as to support the healthy qi of the disease without leaving blood stasis,eliminating the obstruction in the abdomen without harming the healthy qi of the disease,and regulating the qi and blood to balance yin and yang,in order to obtain a significant therapeutic effect.

Objective:To compare the accuracy and efficacy of robot assisted and navigation assisted pedicle screw fixation.Methods:Retrospective analysis of 764 patients with lumbar spine disorders who underwent internal fixation treatment at the Department of Spine Surgery, Honghui Hospital, Xi'an Jiaotong University, from June 2017 to April 2023 were performed. They were divided into the Renaissance group (212 cases), the Tinavi group (301 cases), and the S8 navigation group (251 cases), according to the method of assisted placement of pedicle screws. The operation time, fluoroscopy time, X-ray radiation dose, intra-operative blood loss, accuracy of screw placement, screw revision rate, pain visual analogue scale (VAS), Oswestry disability index (ODI) and postoperative infection rate were compared among the three groups.Results:922 screws were placed in the Renaissance group, 1,260 screws in the Tinavi group, and 1,044 screws in the S8 navigation group. The accuracy of clinically acceptable pedicle screw placement was 92.08% (849/922), 99.68% (1,256/1,260), and 99.43% (1,038/1,044) in the three groups, respectively, with the Renaissance group being smaller than the Tinavi group and the S8 group (χ 2=90.334, P<0.001; χ 2=68.446, P<0.001), and the Tinavi group and the S8 group had no statistically significant difference (χ 2=0.380, P=0.537). The operation time of the three groups was 173.64±62.23 min, 177.11±60.85 min, 176.02±60.93 min, and the intraoperative blood loss was 118.16±58.26 ml, 121.84±55.91 ml, 123.62±59.84 ml, respectively, and the differences between the groups were not statistically significant ( P>0.05). The fluoroscopy time of the three groups was 8.73±2.92 s, 10.67±2.85 s, and 11.31±2.89 s, and the X-ray radiation doses were 18.83±7.41 μSv, 20.40±7.60 μSv, and 22.88±7.47 μSv, respectively, with statistically significant differences between the groups and the two comparisons ( P<0.05). All patients were given follow-up for 3-30 months. Three cases in the postoperative Renaissance group underwent screw revision for nerve root irritation due to screw penetration of the pedicle cortex, and none of the other two groups underwent screw revision. Postoperatively, one case in the Renaissance group and one case in the Tinavi group had superficial infections, which were cured after prolonged antibiotic use. At 3 months postoperatively, the VAS scores for leg pain in the Renaissance group, the Tinavi group, and the S8 navigation group were 3.52±1.14, 3.59±1.12, and 3.39±1.16, and the VAS scores for back pain were 3.54±1.14, 3.57±1.12, and 3.51±1.15, respectively; the ODI scores were 12.48%±4.53%, 12.01%±4.57%, and 12.28%±4.60%, and none of the differences between the groups were statistically significant ( P>0.05). Conclusion:The accuracy of screw placement by the Tinavi robot was comparable to that of the S8 navigation, and both were superior to that of the Renaissance robot; the fluoroscopy time and radiation dose of the Renaissance robot were smaller than those of the Tinavi robot, which was smaller than that of the S8 navigation. The early efficacy of robotics and navigation-assisted pedicle screw internal fixation for lumbar spine disorders is similar.

Objective:To evaluate the effect of the right stellate ganglion block (SGB) on the acute lung injury induced by hind limb ischemia-reperfusion (I/R) in rats.Methods:Twenty-seven SPF healthy male Sprague-Dawley rats, aged 7-8 weeks, weighing 200-250 g, were divided into 3 groups ( n=9 each) by the random number table method: sham operation group (Sham group), hind limb I/R group (I/R group) and right SGB+ hind limb I/R group (SGB+ I/R group). The right hind limb I/R injury model was developed in anesthetized rats in I/R and SGB+ I/R groups, and the right SGB was performed with 0.2% ropivacaine 0.5 ml before the right hind limb ischemia in SGB+ I/R group. The pathological changes of lung tissues were observed with a light microscope, the wet/dry lung weight ratio, PaO 2 and PaCO 2 were determined, and the oxygenation index was calculated. The concentrations of serum malondialdehyde (MDA) and glutathione peroxidase (GSH-Px) were determined using enzyme-linked immunosorbent assay. Results:Compared with Sham group, the wet/dry lung weight ratio, PaO 2, oxygenation index, and GSH-Px concentrations were significantly decreased, and the concentrations of serum MDA were increased in I/R and SGB+ I/R groups ( P<0.05). Compared with I/R group, the wet/dry lung weight ratio, PaO 2, oxygenation index, and GSH-Px concentrations were significantly increased, the concentrations of serum MDA were decreased ( P<0.05), and the pathological changes of lung tissues were significantly attenuated in SGB+ I/R group. There was no significant difference in PaCO 2 among the 3 groups ( P>0.05). Conclusions:The right SGB can alleviate the acute lung injury induced by hind limb I/R, and the mechanism may be related to the inhibition of oxidative stress responses in rats.

OBJECTIVE To investigate the mechanisms by which Pinggan Yishen Decoction(PGYSD)contributes to alleviating target organ damage in spontaneously hypertensive rats.METHODS The chemical components of PGYSD were determined by ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF/MS)and were analyzed by target a-nalysis and functional enrichment combined with network pharmacology methods to predict the potential mechanism of PGYSD in trea-ting hypertension and its target organ damage.Spontaneously hypertensive rats were randomly divided into the model group,low-dose PGYSD group(2 g·kg-1),high-dose PGYSD group(5 g·kg-1),and valsartan group(7.2 mg·kg-1),with 6 rats in each group.Wistar-Kyoto rats were used as the control group,and the control group and the model group were gavaged with normal saline for 8 consecutive weeks.HE and Masson staining were used to observe the pathological damage and fibrosis degree of rat heart and tho-racic aorta.Immunohistochemical staining and Western blot were used to detect the expression level of EGFR in the heart,liver and kidney of rats.Immunofluorescence staining was used to detect the co-localization of EGFR and EEA1 in the heart,liver and kidney of rats.RESULTS Twenty-six components of PGYSD were detected by UPLC-Q-TOF/MS.Network pharmacology revealed that EG-FR,PIK3R1 and EP300 may be key therapeutic targets of action of PGYSD for the treatment of hypertension and its target organ dam-age,and that the treatment of hypertension and its target organ damage by PGYSD may be closely related to EGFR tyrosine kinase in-hibitor resistance,lipids and atherosclerosis and HIF-1 signaling pathway.The high-dose group of PGYSD significantly reduced sys-tolic blood pressure and mean blood pressure in rats(P<0.05,P<0.01),attenuated pathological damage and fibrosis in the heart and thoracic aorta(P<0.01,P<0.001),significantly reduced the expression level of EGFR in the liver and kidney of rats(P<0.01),and treated fibrosis in liver and kidney,reduced the co-localization of EGFR and EEA1 in the kidney of rats(P<0.001),attenuated fibro-sis in kidney.CONCLUSION The paper integrates UPLC-Q-TOF/MS,network pharmacology and spontaneously hypertensive rat model and preliminarily explores the effect mechanism of PGYSD in the treatment of hypertension and its target organ damage,provi-ding a scientific basis for further mechanism research and clinical application of PGYSD in the treatment of hypertension.
