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 identify and characterize one Yokenella regensburgei strain(designated as CXLZQ123) isolated from a case of perionychial abscess. Methods:Strain CXLZQ123 was isolated from a patient with periungual abscess at the Dermatology Department of San County Central Hospital in June 2, 2023. The strain was initially identified through morphological and biochemical tests, followed by mass spectrometry identification, 16S rRNA sequencing and whole-genome sequencing. MEGA 11.0 was used to compare and analyze the strain′s genetic relationship with relevant species in GenBank, and a phylogenetic tree was constructed based on genetic distance to analyze its genetic evolution. Meanwhile, the average nucleotide identity between its genome and similar strains were compared.Results:The strain was identified as a Gram-negative rod. MicroScan WalkAway biochemical tests indicated that the strain was either Yokenella regensburgei (91.47%) or Hafnia alvei (8.53%). MALDI-TOF mass spectrometry confirmed it as Yokenella regensburgei. Based on 16S rRNA gene sequence analysis, the strain showed the highest similarity(99.37%) to CIP 105435 (sequence number NR_104934.1). The 16S rRNA gene sequence of the isolated strain Yokenella regensburgei was submitted to the National Center for Biotechnology Information (NCBI) with the GenBank sequence number of OR230248.1. The whole-genome of CXLZQ123 were sequenced and uploaded (NCBI, SRA sequence number: SRR26510420). The average nucleotide identity between CXLZQ123 and Yokenella regensburgei strains W13 and UU2206353 were 98.82% and 99.04%, respectively. Conclusions:Through morphological observation, biochemical identification, mass spectrometry identification, 16S rRNA and whole-genome sequencing, this pathogenic strain is identified as Yokenella regensburgei. This rare bacterium is sensitive to most detected antibiotics. This study provides diagnostic and treatment experience for Yokenella regensburgei-related infections.

Objective:To access the therapeutic efficacy of newly-designed digital cholangioscope-assisted bedside one-stage lithotomy and biliary drainage for severe acute cholangitis caused by choledocholithiasis.Methods:Data of 26 patients were retrospectively analyzed, who were admitted into the intensive care unit (ICU), Zhongda Hospital, Southeast University, due to choledocholithiasis induced by severe acute cholangitis and underwent cholangioscope-assisted bedside one-stage lithotomy and biliary drainage from June 2020 to February 2022. Clinical outcomes were analyzed.Results:The time interval from disease onset to endoscopic intervention was 36.2±15.5 hours, with 7.2±4.9 hours from ICU admission to endoscopic intervention. Technical success rate was 100.0% in one-stage stone removal and biliary drainage. Except for one mild pancreatitis, no other complication occurred. Acute physiology and chronic health evaluation (APACHE)Ⅱ and sequential organ failure assessment (SOFA) scores prior to endoscopic intervention were 25.2±6.6 and 11.9±3.5, respectively. APACHE Ⅱ scores at day 1, 3, and 7 after endoscopic intervention were 21.7±6.5, 17.2±6.8 and 12.7±7.7, respectively, and SOFA scores were 10.6±2.9, 8.4±3.0 and 5.4±3.7, respectively, all of them were lower than those before operation ( P<0.001). The lengths of ICU stay and total hospitalization were 9.7±5.0 days and 12.8±4.5 days, respectively. In-hospital mortality occurred in 3 (11.5%) patients. According to a 6-month follow-up, one patient died of pneumonia, and another died of acute myocardial infarction. No acute cholangitis re-occurred in those survivors. Conclusion:Newly-designed digital cholangioscope-assisted bedside one-stage lithotomy and biliary drainage demonstrate significant improvements in prognosis, highlighting its safety in managing severe acute cholangitis.

Objective: To investigate whether melatonin (MT) secretion in different parts of the gastrointestinal tract (GIT) exhibits seasonal variations and its correlation with immune regulation. Methods: Sixty Sprague-Dawley rats were divided into control and model groups, and the pineal gland was removed in the model group. Stomach, jejunum, ileum, and colon tissues were obtained during the spring equinox, summer solstice, beginning of autumn, autumn equinox, and winter solstice. The levels of MT, MT receptors (MR), arylalkylamine N-acetyltransferase (AANAT), hydroxyindole-O-methyltransferase (HIOMT), interleukin-2 (IL-2), and interleukin-10 (IL-10) in the GIT were measured using enzyme-linked immunosorbent assay. Results: Except for the stomach, the jejunum, ileum, and the colon showed seasonal tendencies in MT secretion. In the control group, MT secretion in the jejunum and ileum was the highest in the long summer, and colonic MT secretion was the highest in winter. In the model group, MT levels in the colon were highest in the summer. The seasonal rhythms of the MR, AANAT, HIOMT, IL-2, and IL-10 in the colon were roughly similar to those of MT, and changed accordingly after pinealectomy. Conclusions Gastrointestinal MT secretion is related to seasonal changes, and MT secretion in each intestinal segment is influenced by different seasons. The biological effects of MT in the gut are inextricably linked to the mediation of MR, and a hormone-receptor linkage exists between MT and MR. The effect of seasonal changes on the gastrointestinal immune system may be mediated through the regulation of seasonal secretion of MT.

Objective To explore the effect of a phased rehabilitation training programme to relieve shoulder dys-function in patients after neck dissection and to provide effective solutions for postoperative shoulder joint function recov-ery of patients.Methods This study has been reviewed and approved by the Ethics Committee,and informed consent has been obtained from patients.A phased rehabilitaiton training programme for the shoulder after neck dessection was developed through literature review and discussion,and 70 eligible patients from Hospital of Stomatology,Sun Yat-sen University from December 2020 to April 2021 were selected and randomly divided into the test group and control group(35 patients in each group).The control group underwent motor rehabilitation training from 6 weeks postoperative to 1 year after surgery,such as shoulder mobility and coordination training and small range of motion training of the neck,while the test group took part in a rehabilitation training program that included familiarization maneuver training,protective rehabilitation,exercise rehabilitation,and resistance training in the following four stages:preoperative,postop-erative general anesthesia and awake until the removal of stitches,the removal of stitches until 6 weeks after surgery,and 6 weeks after surgery until 1 year after surgery.The frequency of training in both groups was at least 3 days per week,and the length of each training session was 10-15 min.The intensity of exercise was 2-3 points on the Borg Conscious Ex-ercise Intensity Scale(i.e.,mild-to-moderate tachypnea or fatigue).The neck dissection injury index(NDII)was used to evaluate the quality of life related to shoulder joint function at four time points:preoperative,postoperative 3 months,postoperative 6 months,and postoperative 12 months.The higher the score,the better the quality of life.Results 28 cases in the test group and 32 cases in the control group completed a one-year follow-up.At 3 and 6 months postopera-tive,the NDII of the test group was significantly higher than that of the control group[3 months postoperative:test group(93.48±9.36)vs.control group(80.00±11.34)(P＜0.001),6 months postoperative:test group(98.21±4.76)vs.control group(90.70±9.12)(P＜0.001)];12 months after surgery,the NDII of the test group(97.23±4.88)was still higher than that of the control group(96.33±4.49),but the difference was not statistically significant(P=0.458).The difference in NDII scores among subjects at 3,6,and 12 months after surgery was statistically significant in each group(P＜0.001).Conclusion The application of the phased rehabilitation training method in neck dissection patients has a feasibility and could improve the quality of life of patients'shoulder joint function within 6 months after surgery.
