Depression is a common mental disorder in clinical practice, and it falls under the category of depression syndrome in traditional Chinese medicine (TCM). In TCM, Qi depression is considered as the root cause of all depression syndromes. Qi depression can lead to blood stasis, which is a key cause of diseases due to depression syndrome. Therefore, treating stasis is an important therapeutic approach for depression syndrome. Salviae Miltiorrhizae Radix et Rhizoma, a representative herbal medicine for activating blood and removing stasis, is effective in activating blood, removing stasis, dredging meridians, and alleviating pain. Currently, it is primarily used in clinical practice to treat cardiovascular and cerebrovascular diseases, such as neurasthenia, coronary heart disease, insomnia, and palpitations. The active components of Salviae Miltiorrhizae Radix et Rhizoma are complex and exhibit a variety of pharmacological effects. These components include water-soluble salvianolic acids and lipid-soluble tanshinones. Modern pharmacological studies have proven that Salviae Miltiorrhizae Radix et Rhizoma and its active components possess antioxidant, anti-inflammatory, anti-tumor, anti-fibrosis, and neuroprotective properties. In recent years, increasing attention has been paid to the pharmacological effects and mechanisms of Salviae Miltiorrhizae Radix et Rhizoma and its active components in treating depression. This paper systematically reviews the antidepressant mechanisms of Salviae Miltiorrhizae Radix et Rhizoma and its main active components from the regulation of monoamine neurotransmitters, the hypothalamic-pituitary-adrenal axis, neurotrophic factors, and neuroinflammation. In addition, this paper summarizes the clinical applications of the prescriptions containing Salviae Miltiorrhizae Radix et Rhizoma in the treatment of depression, providing new insights for further research on the pharmacological mechanisms of Salviae Miltiorrhizae Radix et Rhizoma in treating depression.

With the main pathological features of glomerulosclerosis and interstitial fibrosis, renal fibrosis is a key pathological process causing chronic kidney disease to progress to end-stage disease. As a cellular autophagic process, mitochondrial autophagy plays a crucial role in maintaining mitochondrial mass and functional stability. Mitochondrial dysfunction is considered to be one of the key factors driving the progression of fibrosis. Phosphatase and tension protein homologue (PTEN) induce various signalling pathways such as putative kinase 1/parkin, Nip3-like protein X/Bcl-2 interacting protein 3, and FUN14 structural domain-containing protein 1 to activate mitochondrial autophagy to participate in the regulation of fibrogenic factors, amelioration of oxidative stress, and inhibition of inflammatory response and apoptosis, which in turn effectively slows down the progression of renal fibrosis. Studies have shown that traditional Chinese medicine monomers and compound preparations, including phenolics, terpenoids, ketones, and alkaloids, can regulate mitochondrial autophagy-related signalling pathways and achieve significant clinical efficacy in intervening in the progression of renal fibrosis for the treatment of chronic kidney disease. This paper summarized the mechanism of mitochondrial autophagy and the research progress of traditional Chinese medicine intervention in renal fibrosis to provide new ideas for the study of the mechanism of traditional Chinese medicine in treating renal fibrosis.

Objective To evaluate the therapeutic efficacy for surgical treatments among patients with hepatic cystic echinococcosis in Gansu Province from 2006 to 2023, so as to provide insights into optimization of the diagnosis and treatment strategies against hepatic cystic echinococcosis. Methods The demographic and clinical data of all echinococcosis cases included in central government fiscal transfer payment program for echinococcosis control and undergoing surgical treatments in Gansu Province from 2006 to 2023 were captured. Hepatic cystic echinococcosis patients with complete medical records and follow-up data were included in the study, and patients’ characteristics, including hospital where patients received diagnosis and treatment, methods of case identification, year of surgery, classification of lesions, number of lesions, size of lesions, course of disease, surgical methods, and post-surgical follow-up data. The cure and recurrence of hepatic cystic echinococcosis were evaluated according to the Guidelines for Management of Echinococcosis Patients in the Central Government Fiscal Transfer Payment Program, and the cure and recurrent rates were calculated. Results Data were collected from 1 686 surgical patients with hepatic cystic echinococcosis. According to the inclusion and exclusion criteria, 1 222 hepatic cystic echinococcosis patients undergoing surgical treatments were included during the period from 2006 to 2022, including 1 166 cured patients (95.42%) and 88 patients with postsurgical recurrence (7.20%), and the cure rate of surgical treatments appeared a tendency towards a rise among patients with hepatic cystic echinococcosis from 2008 to 2022 (χ2trend = 19.39, P < 0.05). The cure rates of hepatic cystic echinococcosis were 100% (177/177), 94.81% (128/135) and 94.62% (861/910) among patients detected through regular physical examinations, screened by the central government fiscal transfer payment program for echinococcosis control, and those who passively sought healthcare services, respectively (χ2 = 9.95, P < 0.05). The cure rates of hepatic cystic echinococcosis were 95.96% (1 046/1 090) among patients with a disease course of 2 years and less and 90.90% (120/132) among patients with a disease course of over 2 years (χ2 = 6.87, P < 0.05), and there were significant differences in the cure rates among patients with hepatic cystic echinococcosis in terms of number of lesions (χ2 = 24.44, P < 0.05) and surgical methods (P < 0.05). The cure rate of hepatic cystic echinococcosis patients was significantly higher following initiation of the central government fiscal transfer payment program for echinococcosis control (96.06%, 1 096/1 141) than before the program (86.42%, 70/81) (χ2 = 16.06, P < 0.05), and the cure rate of hepatic cystic echinococcosis patients was significantly higher in designated hospitals (96.48%, 741/768) than in non-designated hospitals (93.37%, 366/392) (χ2 = 5.78, P < 0.05). The median follow-up period was 4 (interquartile range, 7) years among 1 222 hepatic cystic echinococcosis patients undergoing surgical treatments. The recurrent rate of hepatic cystic echinococcosis appeared a tendency towards a decline from 2008 to 2022 (χ2trend = 36.86, P < 0.05), with a reduction from 23.08% (9/39) in 2008 to 1.85% (1/54) in 2021, and the post-surgical recurrence rate of hepatic cystic echinococcosis was lower following initiation of the central government fiscal transfer payment program for echinococcosis control (5.87%, 67 / 1 141) than before the program (25.93%, 21/81) (χ2 = 45.51, P < 0.05). In addition, the post-surgical recurrence rate of hepatic cystic echinococcosis was higher in non-designated hospitals (10.46%, 41/392) than in designated hospitals (5.60%, 43/768) (χ2 = 9.12, P < 0.05), and there was a significant difference in the post-surgical recurrence rate among patients with hepatic cystic echinococcosis in terms of surgical methods (P < 0.05), with the highest recurrence rate (11.54%) seen among patients undergoing percutaneous fine-needle aspiration of cyst fluids-based surgical procedures (P < 0.05). Conclusion Since the initiation of the central government fiscal transfer payment program for echinococcosis control in Gansu Province in 2006, an increase in the surgical cure rate and a reduction in the recurrence of hepatic cystic echinococcosis had been found among patients with hepatic cystic echinococcosis, indicating a high overall therapeutic efficacy.

General anesthesia, pivotal for surgical procedures, requires precise depth monitoring to mitigate risks ranging from intraoperative awareness to postoperative cognitive impairments. Traditional assessment methods, relying on physiological indicators or behavioral responses, fall short of accurately capturing the nuanced states of unconsciousness. This study introduces a machine learning-based approach to decode anesthesia depth, leveraging EEG data across different anesthesia states induced by propofol and esketamine in rats. Our findings demonstrate the model's robust predictive accuracy, underscored by a novel intra-subject dataset partitioning and a 5-fold cross-validation method. The research diverges from conventional monitoring by utilizing anesthetic infusion rates as objective indicators of anesthesia states, highlighting distinct EEG patterns and enhancing prediction accuracy. Moreover, the model's ability to generalize across individuals suggests its potential for broad clinical application, distinguishing between anesthetic agents and their depths. Despite relying on rat EEG data, which poses questions about real-world applicability, our approach marks a significant advance in anesthesia monitoring.

ObjectiveTo investigate the role and mechanism of podoplanin (PDPN) in hepatic stellate cell (HSC) activation and liver fibrosis. MethodsLiver biopsy samples were collected from 75 patients with chronic hepatitis B who attended Department of Infectious Diseases, Putuo Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, for the first time from September 2019 to June 2022, and RT-PCR and immunohistochemistry were used to measure the expression of PDPN in liver tissue of patients in different stages of liver fibrosis. A total of 12 male C57/BL6 mice were randomly divided into control group and model group. The mice in the model group were given intraperitoneal injection of 10% CCl4, and those in the control group were injected with an equal volume of olive oil, for 6 weeks. HE staining and Sirius Red staining were used to observe liver histopathological changes; primary mouse liver cells were separated to measure the mRNA expression of PDPN in various types of cells; primary mouse HSCs were treated with PDPN protein, followed by treatment with the NF-κB inhibitor BAY11-708, to measure the expression of inflammatory factors in HSCs induced by PDPN. The independent-samples t test was used for comparison of normally distributed continuous data between two groups; a one-way analysis of variance was used for comparison between multiple groups, and the least significant difference t-test was used for further comparison between two groups. The Spearman correlation analysis was used to investigate data correlation. ResultsAs for the liver biopsy samples, there was a relatively low mRNA expression level of PDPN in normal liver, and there was a significant increase in the mRNA expression level of PDPN in liver tissue of stage S3 or S4 fibrosis (all P<0.001). Immunohistochemical staining showed that PDPN was mainly expressed in the fibrous septum and the hepatic sinusoid, and the PDPN-positive area in S4 liver tissue was significantly higher than that in S0 liver tissue (t=8.892, P=0.001). In normal mice, PDPN was mainly expressed in the hepatic sinusoid, and there was a significant increase in the expression of PDPN in CCl4 model mice (t=0.95, P<0.001), mainly in the fibrous septum. RT-PCR showed a significant increase in the mRNA expression of PDPN in the CCl4 model mice (t=11.25, P=0.002). Compared with hepatocytes, HSCs, Kupffer cells, and bile duct endothelial cells, hepatic sinusoidal endothelial cells showed a significantly high expression level of PDPN (F=20.56, P<0.001). Compared with the control group, the primary mouse HSCs treated by PDPN protein for 15 minutes showed significant increases in the mRNA expression levels of the inflammation-related factors TNFα, CCL3, CXCL1, and CXCR1 (all P<0.05), and there were significant reductions in the levels of these indicators after treatment with BAY11-7082 (all P<0.05). ConclusionThere is an increase in the expression of PDPN mainly in hepatic sinusoidal endothelial cells during liver fibrosis, and PDPN regulates HSC activation and promotes the progression of liver fibrosis via the NF-κB signaling pathway.

ObjectiveTo investigate the mechanism of action of Xiayuxue decoction in inhibiting nonalcoholic fatty liver disease (NAFLD) induced by high-fat diet in mice by regulating nucleotide binding oligomerization domain like receptor containing pyrin domain protein 6 (NLRP6). MethodsA total of 15 male C57BL/6 mice were randomly divided into low-fat diet (LFD) group, high-fat diet (HFD) group, and Xiayuxue decoction-HFD group (XYXD group), with 5 mice in each group. Liver function parameters (alanine aminotransferase [ALT] and aspartate aminotransferase [AST]) and blood lipid metabolic indicators (triglycerides [TG] and total cholesterol [TC]) were measured; HE staining and oil red O staining were performed for liver tissue to observe histomorpholoty and lipid droplet deposition; quantitative real-time PCR was used to measure the expression levels of inflammatory factors (tumor necrosis factor-α [TNF-α], interleukin-1β [IL-1β], interleukin-18 [IL-18], and NLRP6) in liver tissue; Western blot was used to measure the protein expression levels of NLRP6, nuclear factor-kappa B (NF-κB), and NF-κB p65; immunohistochemistry was used to measure the expression of NLRP6 and CD68. Mouse Raw264.7 cells were treated with palmitic acid (PA), lipopolysaccharide, and serum containing Xiayuxue decoction to observe inflammation. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the LFD group, the HFD group had significant increases in the serum levels of ALT, AST, TC, and TG (all P<0.05). Liver histopathological examination showed that the HFD group had marked hepatic steatosis and a signficant increase in NAS score (P<0.05), and quantitative real-time PCR showed significant increases in the inflammatory factors such as IL1β and IL-18 and a significant reduction in the expression of NLRP6 (all P<0.05). Immunohistochemistry showed that the expression of NLRP6 showed a similar trend as that of the macrophage marker CD68. Western blot showed that after the downregulation of NLRP6 expression, there was a significant increase in phosphorylated NF-κB p65 (P<0.05). Compared with the HFD group, Xiayuxue decoction effectively improved liver inflammation, upregulated the expression of NLRP6, and downregulated phosphorylated NF-κB p65 in HFD mice (all P<0.05). After Raw264.7 cells were treated with PA, NLRP6 was downregulated to promote the progression of inflammation (P<0.05), and treatment with Xiayuxue decoction could upregulate NLRP6 and inhibit inflammation NF-κB (P<0.05). ConclusionXiayuxue decoction can effectively improve hepatic steatosis and liver inflammation in a mouse model of NAFLD, possibly by regulating NLRP6/NF-κB to alleviate macrophage activation.

OBJECTIVE To investigate the prognostic value of pre-treatment serum lactate dehydrogenase(LDH)levels in patients with locally recurrent nasopharyngeal carcinoma(NPC)treated with salvage intensity-modulated radiotherapy(IMRT)and to determine its association with rT staging.METHODS The records of 97 patients with locally relapsed and non-metastatic NPC who received salvage IMRT treatment in our center from January 2018 to April 2022 were collected,including 51 patients who died,18 patients with distant metastases,30 patients with local failure,and 67 patients with prognostic adverse events(death,distant tumors/local metastases).Clinical data,local failure-free survival(LFFS),distant metastasis-free survival(DMFS)and overall survival(OS)were obtained from all patients,and the relationship between LDH and the prognosis of salvage IMRT therapy in NPC patients was analyzed.RESULTS The serum LDH level before salvage IMRT was significantly higher in the death[221.25(178.24,339.13)U/L vs.124.82(79.0,159.50)U/L,Z=-5.122],local failure[230.75(170.89,394.50)U/L vs.157.85(91.78,216.95)U/L,Z=-3.442],distant metastasis[261.62(153.55,465.50)U/L vs.168.98(101.75,237.75)U/L,Z=-2.478]and poor prognosis group[220.05(167.20,506.16)U/L vs.93.45(69.95,154.35)U/L,Z=-6.018],and all P<0.05.Serum LDH levels were divided into dichotomous variables according to median values(≥177.50 U/L vs.<177.50 U/L),the Cox univariate model found that the hazard ratios of LDH affecting LFFS,DMFS,OS and toxic-related death(TRD)were 3.759(1.660-8.558),4.217(1.383-12.861),3.226(1.715-6.069),3.363(1.750-6.463),P<0.05.LDH remained an independent prognostic factor for LFFS,DMFS,OS,and TRD in multivariate regression analysis(P<0.05).Compared with patients with LDH<177.50 U/L,more patients in the LDH≥177.50 U/L group had local progression-related death,and the no LFFS stage,no DMFS stage and OS were shorter in the LDH≥177.50 U/L group(log rank=11.624,7.559,14.758),P<0.05.In predicting overall survival,adding LDH to the rT stage is preferable to the rT stage alone.CONCLUSION LDH is an important factor in predicting LFFS,DMFS,OS,and TRD after saving IMRT in patients with locally relapsed,non-metastatic NPC,and the value of LDH combined with rT staging in predicting overall survival is high.

OBJECTIVE To investigate the effects of catalpol on H2O2-induced osteoblast injury and its mechanism. METHODS The osteoblasts MC3T3-E1 were separated into control group, model group, empty group (transfected with empty plasmid), catalpol group (100 μmol/L), catalpol+forkhead box O3 (FoxO3) overexpression group (100 μmol/L catalpol+ transfected with FoxO3 overexpression plasmid). After catalpol treatment and transfection, except for control group, other groups were induced with H2O2 to establish osteoblast oxidative stress model. The cell viability, apoptotic rate, alkaline phosphatase (ALP) activity, optical density (OD) value of calcium nodule, mean fluorescence intensity (MFI) of reactive oxygen species (ROS), antioxidant enzyme activity [superoxide dismutase (SOD), catalase (CAT)], the levels of inflammatory factors [interleukin-6 (IL-6), IL-1β], and the expressions of FoxO3/Wnt/β-catenin signaling pathway-related proteins were detected in each group. RESULTS Compared with the control group, the cell viability, ALP activity, OD value of calcium nodule, activities of antioxidant enzyme, and the protein expressions of Wnt and β-catenin were decreased significantly in the model group, while apoptotic rate, MFI levels of ROS, inflammatory factor levels and the protein expression of FoxO3 were all increased significantly (P<0.05). Compared with the model group, above indicators of the empty group had no significant change (P>0.05), while those of catalpol group were reversed significantly (P<0.05). Compared with the catalpol group, the reversal effect of the changes in the above indicators was significantly weakened in the catalpol+FoxO3 overexpression group cells (P<0.05). CONCLUSIONS Catalpol can activate Wnt/β-catenin signaling pathway by down-regulating FoxO3, thereby inhibiting H2O2-induced MC3T3-E1 oxidative stress and inflammation reaction, enhancing cell viability and osteogenic differentiation activity, and alleviating apoptosis injury.
