Taking " harmony of body and spirit" as the theoretical core in Huangdi Neijing and the functional nature and executive structure of the five emotions system as clues, this paper explores and analyzes the relevant theories of the five emotions system in ancient Chinese medicine literature. It is found that the five emotions system is a highly ordered and integrated collection of five functional states. It often resides in the five zang viscera, it operates between the meridians and the xuanfu through the elevation and movement of the qi, and it is the pivotal point for the operation of the qi and blood of the organism, the interactive conduction of information, and the unity of form, emotion, and qi. Therefore, this paper starts from the point of view of system science. It is proposed that the primordial spirit exercises control over the five emotions and the five emotions provide nutrition to the primordial spirit, and that the two are not " islands of information" but have a dynamic and hierarchical internal connection. The executive structure of the five emotions system, namely, the meridians, the xuanfu, and the five zang viscera, is the pivot, and it is recognized that the operation of the five emotions system is a process with self-organizing characteristics and orderly and eternal motion. We think of the qi, blood, ying, and essence as the basis of occurrence, the meridian as the execution channel, and the xuanfu as the place for the spiritual mechanism to enter and exit; the five zang viscera serve as a dwelling place, and ministerial fire serves as the source of energy. This paper serves as reference for future research related to the executive structure of the five emotions system of traditional Chinese medicine.

Objective:To explore the long-term prognosis of surgical treatment for peri-gastric cardial gastrointestinal stromal tumors (GISTs).Methods:In this retrospective cohort study, we analyzed selected data of patients with peri-gastric cardial GISTs who had undergone radical surgery in Renji Hospital, Shanghai Jiao Tong University School of Medicine, from May 1998 to December 2020. Inclusion criteria comprised radical surgery, pathologically confirmed primary gastric GIST; tumor involving the cardia or within 5 cm of the cardia dentate line; and relatively complete clinical data, including adjuvant therapy and follow-up information. Exclusion criteria comprised presence of multiple GISTs or a history of other malignancies and evidence of distant metastasis or local invasion either preoperatively or intraoperatively. The study cohort comprised 170 patients, including 98 men (57.6%), with a median age of 62 years (range: 30–85 years). Tumors were located less than 2 cm from the dentate line in 97 patients and 2 to 5 cm from it in 73. Tumor growth patterns were intraluminal in 85 patients, extraluminal in 61, and both intraluminal and extraluminal in 24. Tumor diameters were ≤2.0 cm in 11 patients, 2.1–5.0 cm in 90, 5.1–10.0 cm in 60, and >10.0 cm in nine. Mitosis counts (per 50 high-power fields) were ≤5 in 129 patients, 5–10 in 21, and >10 in 20. Risk stratification categorized patients as at extremely low risk in 10 patients, at low risk in 79, at intermediate risk in 43, and at high risk in 38. The guidelines for treatment were adhered to in 128 patients; 21 of 38 high-risk patients had received imatinib for ≥3 years. Primary outcomes included surgical procedure, overall survival (OS), and disease-free survival (DFS). Data were analyzed using SPSS 28.0 and R studio.Results:Ninety of the patients had undergone open surgery, including five total gastrectomies, 49 proximal gastrectomies, and 36 local resections. In addition, 80 patients had undergone laparoscopic local resections. The median follow-up time was 82.5 months (range 13–278 months). The OS rates at 1, 3, 5, and 10 years were 100.0%, 98.2%, 96.9%, and 89.6%, respectively. The DFS rates at 1, 3, 5, and 10 years were 99.4%, 95.9%, 92.0%, and 88.0%, respectively. After adjusting for tumor diameter, mitotic count, adjuvant therapy, distance from the cardia, and growth pattern using propensity score matching, we found no statistically significant differences in DFS and OS between proximal gastrectomy and partial resection, or between open local resection and laparoscopic local resection (all P>0.05). Conclusions:Surgical treatment of peri-gastric cardial GISTs has a favorable long-term prognosis. The oncological efficacy of proximal gastrectomy and partial resection, whether performed via laparoscopic or open approaches, appears comparable for treatment of peri-gastric cardial GISTs.

ObjectiveGlutathione (γ-glutamyl-L-cysteinylglycine, GSH) is the most abundant non-protein compound containing sulfhydryl (―SH) groups in cells. It serves as a source of reducing equivalents, effectively neutralizing harmful reactive substances, and playing a crucial role in maintaining cellular redox balance. Therefore, sensitive detection and accurate measurement of GSH levels in tissues are of great importance. In this work, we presents a novel method for GSH detection utilizing electron paramagnetic resonance (EPR) spectroscopy. MethodsInitially, ABTS (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonate acid)) solution was mixed with K₂S₂O₈ solution and reacted in the dark for 12 to 16 h to prepare ABTS·⁺ solution, which was then quantified using UV-Vis spectroscopy. Subsequently, the concentration of glutathione (GSH) was determined based on the changes in the EPR signal of ABTS·⁺. On this basis, the optimal reaction time and temperature were explored to establish a standard equation correlating the EPR signal intensity of ABTS·⁺ with GSH concentration. Finally, the derived standard curve was employed to quantitatively analyze the GSH concentration in whole blood from C57BL/6J mice, and the results were compared with those reported in the literature to verify the accuracy of the method. ResultsThe experimental results demonstrate that this method has a linear detection range from50 nmol/L to 15 μmol/L for GSH, spanning two orders of magnitude, with a limit of detection (LOD) at0.50 nmol/L. The measured GSH content in mouse whole blood is (10 660±706) nmol/g Hb, which agrees with the value of (11 200±237) nmol/g Hb as previously reported. Furthermore, a similar method was developed for detection of glutathione disulfide (GSSG) at higher reaction temperature. ConclusionThis article presents a novel assay for the rapid detection of GSH using the intensity of EPR signal from ABTS·⁺ as indicator. This method demonstrates enhanced detection sensitivity and a broader linear range compared to conventional colorimetric methods. Furthermore, we have extended the application of this method to detect GSH content in blood samples efficiently and accurately, offering valuable information for assessing tissue redox balance, thus holding significant potentials.

Objective:To analyze the distribution and genomic characteristics of SARS-CoV-2 variants isolated from imported cases of COVID-19 in Sichuan Province from December 2022 to January 2023.Methods:This study selected 108 nasal and throat swab samples with fluorescence threshold (Ct)≤32 that were collected from imported COVID-19 cases in Sichuan Province from December 2022 to January 2023. Targeted amplification and Illumina NextSeq? 2000 system were used for whole-genome sequencing. Nextclade and Pangolin online platforms were used to determine the virus genotypes and analyze the mutation loci. A phylogenetic tree was constructed using maximum likelihood.Results:A total of 55 SARS-CoV-2 whole genome sequences with coverage of >95% were obtained, and all of the strains were Omicron variants. Compared with the sequence of reference strain Wuhan-Hu-1, the median number of nucleotide mutation sites of 21L, 22B, 22D, 22E, and 22F genotypes were 93, 75, 92, 78, and 92, and the median number of amino acid mutation sites were 68, 53, 68, 69, and 65, respectively. From December 2022 to January 2023, the predominant circulating SARS-CoV-2 variants from imported cases in Sichuan Province were BA.5.2 (10.91%, 6/55), XBB.1.1 (9.10%, 5/55), BF.7.14 (7.23%, 4/55), and BQ.1.1 (7.23%, 4/55).Conclusions:The distribution of SARS-CoV-2 variants can reflect the global epidemic trend to a certain extent. However, it is different from the distribution of local circulating variants in the Chinese mainland. The XXB variants with transmission advantages can be detected in large numbers of inbound travelers before becoming the predominant circulating strains in the Chinese mainland.

AIM: To explore the relationship between the changes of serum circFTO and microRNA-141-3p(miR-141-3p)levels and the different disease stages of diabetes retinopathy.METHODS: A total of 198 patients with type 2 diabetes admitted to our hospital from October 2019 to November 2022 were collected as the study subjects, the patients were grouped into non diabetes retinopathy(NDR)group(70 cases), non proliferative diabetes retinopathy(NPDR)group(66 cases)and proliferative diabetes retinopathy(PDR)group(62 cases)according to different stages; meantime, 67 volunteers with normal physical examination results were collected as the control group. The levels of serum circFTO and miR-141-3p were detected by real-time fluorescent quantitative PCR(qRT-PCR); Pearson correlation analysis was used to examine the correlation between the serum circFTO, miR-141-3p and various indicators in patients with diabetes retinopathy; multivariate Logistic regression analysis was applied to explore the influencing factors of diabetes retinopathy.RESULTS: CircFTO, systolic blood pressure(SBP), and diastolic blood pressure(DBP)in PDR group were higher than those in control group, NDR group and NPDR group, while miR-141-3p and high-density lipoprotein cholesterol(HDL-C)were lower than those in control group, NDR group and NPDR group(P<0.05). Fasting blood glucose(FPG)and glycosylated hemoglobin(HbA1c)in NDR group, NPDR group and PDR group were higher than those in the control group(all P<0.05). The course of disease in PDR group was longer than that in NDR group and NPDR group(P<0.05). Serum circFTO in patients with diabetes retinopathy was positively correlated with SBP, DBP, FPG, HbA1c, and miR-141-3p was negatively correlated with SBP, DBP, FPG, HbA1c(all P<0.05). CircFTO was a risk factor for diabetes retinopathy, and miR-141-3p was a protective factor for diabetes retinopathy(P<0.05).CONCLUSION: Serum circFTO is obviously increased and miR-141-3p is obviously decreased in patients with diabetes retinopathy, both of them are closely related to disease stage, and are expected to become important indicators for evaluating disease progress.

AIM: To explore the clinical efficacy of different anti-vascular endothelial growth factor(VEGF)drugs in the treatment of diabetic macular edema(DME), and analyze their relationship with optical coherence tomography(OCT)classification.METHODS: A total of 45 DME patients treated with ranibizumab(admitted to our hospital from February 2020 to February 2022)were selected as the ranibizumab group, and 45 DME patients treated with conbercept during the same period were selected as the conbercept group. The ranibizumab group was treated with retinal photocoagulation combined with ranibizumab, and the conbercept group was treated with retinal photocoagulation combined with conbercept. The improvement of symptoms(improvement time of macular edema, time of retinal thickness returning to normal, disappearance time of neovascularization and absorption time of fundus hemorrhage), levels of serum interleukin-6(IL-6)and VEGF, central macular thickness(CMT), best corrected visual acuity(BCVA), and complications were compared between the two groups, and the relationship between their clinical efficacy and different OCT types were analyzed.RESULTS: There was no significant difference in the improvement time of macular edema, time of retinal thickness returning to normal, disappearance time of neovascularization and absorption time of fundus hemorrhage between the two groups(P>0.05); After treatment, the values of IL-6, VEGF and BCVA in the two groups were significantly lower than those before treatment(P<0.01), but there was no significant difference between the two groups(P>0.05); compared with before treatment, CMT was significantly decreased in both groups after treatment(P<0.05), and compared with ranibizumab group, the CMT was significantly decreased in the conbercept group(P<0.01); there was no significant difference in the incidence of complications between two groups(P>0.05); there were significant differences in the total effective rate among patients with serous retinal detachment(SRD), cystoid macular edema(CME)and diffuse retinal thickening(DRT; P<0.05), among which DRT had the highest total effective rate and SRD had the lowest total effective rate.CONCLUSION: Both conbercept and ranibizumab in the treatment of DME can effectively improve the clinical symptoms of patients and reduce the inflammatory response, but conbercept can better reduce the level of CMT, and has better treatment effect on DRT-type DME patients.

This study aims to explore the influence of Polygonati Rhizoma on the pyroptosis in the rat model of diabetic macroangiopathy via the NOD-like receptor thermal protein domain associated protein 3(NLRP3)/cysteinyl aspartate specific proteinase-1(caspase-1)/gasdermin D(GSDMD) pathway. The rat model of diabetes was established by intraperitoneal injection of streptozotocin(STZ) combined with a high-fat, high-sugar diet. The blood glucose meter, fully automated biochemical analyzer, hematoxylin-eosin(HE) staining, enzyme-linked immunosorbent assay, immunofluorescence, immunohistochemistry, and Western blot were employed to measure blood glucose levels, lipid levels, vascular thickness, inflammatory cytokine levels, and expression levels of pyroptosis-related proteins. The mechanism of pharmacological interventions against the injury in the context of diabetes was thus explored. The results demonstrated the successful establishment of the model of diabetes. Compared with the control group, the model group showed elevated levels of fasting blood glucose, total cholesterol(TC), triglycerides(TG) and low-density lipoprotein cholesterol(LDL-c), lowered level of high-density lipoprotein cholesterol(HDL-c), thickened vascular intima, and elevated serum and aorta levels of tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β) and interleukin-18(IL-18). Moreover, the model group showed increased NLRP3 inflammasomes and up-regulated levels of caspase-1 and GSDMD in aortic vascular cells. Polygonati Rhizoma intervention reduced blood glucose and lipid levels, inhibited vascular thickening, lowered the levels of TNF-α, IL-1β, IL-18 in the serum and aorta, attenuated NLRP3 inflammasome expression, and down-regulated the expression levels of caspase-1 and GSDMD, compared with the model group. In summary, Polygonati Rhizoma can slow down the progression of diabetic macroangiopathy by inhibiting pyroptosis and alleviating local vascular inflammation.
