This study identified blood-entering components of Anshen Dropping Pills and explored their anti-insomnia effects and mechanisms. The main blood-entering components of Anshen Dropping Pills were detected and identified by UPLC-Q-TOF-MS/MS. The rationality of the formula was assessed by using enrichment analysis based on the relationship between drugs and symptoms, and core targets of its active components were selected as the the potential anti-insomnia targets of Anshen Dropping Pills through network pharmacology analysis. Furthermore, protein-protein interaction(PPI) network, Gene Ontology(GO) enrichment analysis, and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway analysis were performed on the core targets. An active component-core target network for Anshen Dropping Pills was constructed. Finally, the effects of low-, medium-, and high-dose groups of Anshen Dropping Pills on sleep episodes, sleep duration, and sleep latency in mice were measured by supraliminal and subliminal pentobarbital sodium experiments. Moreover, total scores of the Pittsburgh sleep quality index(PSQI) scale was used to evaluate the changes before and after the treatment with Anshen Dropping Pills in a clinical study. The enrichment analysis based on the relationship between drugs and symptoms verified the rationality of the Anshen Dropping Pills formula, and nine blood-entering components of Anshen Dropping Pills were identified by UPLC-Q-TOF-MS/MS. The network proximity revealed a significant correlation between eight components and insomnia, including magnoflorine, liquiritin, spinosin, quercitrin, jujuboside A, ginsenoside Rb_3, glycyrrhizic acid, and glycyrrhetinic acid. Network pharmacology analysis indicated that the major anti-insomnia pathways of Anshen Dropping Pills involved substance and energy metabolism, neuroprotection, immune system regulation, and endocrine regulation. Seven core genes related to insomnia were identified: APOE, ALB, BDNF, PPARG, INS, TP53, and TNF. In summary, Anshen Dropping Pills could increase sleep episodes, prolong sleep duration, and reduce sleep latency in mice. Clinical study results demonstrated that Anshen Dropping Pills could decrease total scores of PSQI scale. This study reveals the pharmacodynamic basis and potential multi-component, multi-target, and multi-pathway effects of Anshen Dropping Pills, suggesting that its anti-insomnia mechanisms may be associated with the regulation of insomnia-related signaling pathways. These findings offer a theoretical foundation for the clinical application of Anshen Dropping Pills.

Cancer stem cells (CSCs), a small subset of cells in the tumor bulk with the ability of self-renewal and differentiation, are the key to tumor occurrence, metastasis, drug resistance and relapse. CSCs are resided in a specific microenvironment, and their number maintenance, self-renewal and differentiation are precisely regulated by the microenvironment, and the immune microenvironment is one of the most critical microenvironments for CSCs. In recent years, tumor immunotherapy has achieved great success, but drug resistance and recurrence are frequently occurred after immunotherapy. Compared with non-CSC tumor cells, CSCs harbor stronger immune escape ability, and their roles in tumor immune escape are increasingly followed. In this review, we described the discovery history and lineage sources of CSCs, focused on immune cells in the CSC microenvironment, such as tumor-infiltrating lymphocytes, tumor-associated macrophages, and tumor-associated dendritic cells, and analyzed the mechanism of CSC-immune cell interaction. Intervention strategies targeting CSCs and their immune microenvironment are also described. With the development and application of advanced technologies such as CSC-immune cell co-culture, single-cell sequencing and lineage tracing, the immune escape of CSCs can be suppressed by targeting the interaction between CSCs and immune cells or reversing the immunosuppressive microenvironment, which is expected to provide potential solutions to the problems of drug resistance and relapse in tumor immunotherapy.

BACKGROUND:Recently,regenerative endodontic therapy is a promising alternative to the maturation of tissue engineering.Inflammatory microenvironment plays a key role in regulating pulp regeneration. OBJECTIVE:To focus on the change in the inflammatory pulp microenvironment,the balance between inflammation and regeneration,and the research advances in tissue-engineered regenerative endodontic therapy within the context of the inflammatory microenvironment to provide a reference for future investigations into regenerative endodontic therapy. METHODS:We conducted a literature search on PubMed and CNKI using search terms"pulp regeneration,inflammation,regenerative endodontic therapy,tissue engineering"in Chinese and English for articles published between 2013 and 2023.The review finally included 61 relevant articles. RESULTS AND CONCLUSION:(1)The changes in the microenvironment of pulpitis involve a complex interplay of cellular and molecular reactions,which,as inflammation progresses,ultimately the microenvironment hinders tissue repair more than facilitates it.(2)Inflammation can promote dental pulp regeneration through stem cell recruitment and activate the complement system,but it can also hinder the regenerative process through immunosuppression and fibrosis.(3)Tissue engineering's three components(stem cells,growth factors,scaffold materials)collaborate to balance inflammation and regeneration,for example,by using interleukin-6 to regulate dental pulp stem cells and foster a regenerative environment.(4)Current research has been largely silent on infection and inflammation issues.The mechanisms underlying changes in the microenvironment of pulpitis are still not fully understood.One promising avenue for improving the clinical applicability of regenerative dental pulp therapy is to achieve precise regulation of the inflammatory-regeneration balance and create a regenerative microenvironment by synergistically leveraging the three elements of tissue engineering.However,this field of investigation still exhibits significant gaps in understanding,necessitating further exploration into innovative strategies for facilitating dental pulp regeneration under inflammation.As such,additional animal experimentation and randomized clinical trials are required to establish a robust foundation for the clinical practice of tissue engineering-based regenerative dental pulp therapy.

Objective:
human cysteine protease inhibitor S; helicobacter pylori antibody typing; human epidermal growth factor receptor 2 ; gastric cancer; pathological stage; gastric cancer lymph node metastasis
Methods:
A total of 150 gastric cancer patients admitted to Chaohu Hospital Affiliated to Anhui Medical University for surgery from December 2021 to December 2023 were selected as the study objects. Serum CST4 and HP antibody typing were performed before surgery, and HER2 expression levels in gastric cancer tissues were detected by immunohistochemistry after surgery. The clinicopathological data of gastric cancer patients with different serum CST4, HP antibody types and HER2 expression were compared and the correlation was analyzed. ROC curve was used to compare the predictive value of single and combined detection of serum CST4, HP antibody typing and HER2 expression in lymph node metastasis and TNM staging of gastric cancer.
Results:
Patients with CST4, HPI and HER2-positive expression had deeper tumor invasion and were more likely to develop distant lymph node metastasis, and TNM stages were more likely to occur in Ⅲ and Ⅳ stages(P<0.05). Meanwhile, patients with CST4 positive expression were more likely to have vascular and nerve invasion(P<0.05). In patients with HPI positive expression, tumors were more likely to occur in the cardia and the bottom of the stomach, and the tumor diameter was larger and vascular invasion was more likely(P<0.05), while HER2 was negatively correlated with the degree of tumor differentiation, and the tumors were more likely to occur in high and secondary differentiation(P<0.05). ROC curve analysis showed that the AUC of single and combined detection of serum CST4, HPI and HER2 expression to predict lymph node metastasis of gastric cancer were 0.780, 0.676, 0.611 and 0.872, respectively(P<0.05). The AUC for TNM stage diagnosis of gastric cancer were 0.762, 0.635, 0.613 and 0.801(P<0.05), respectively. The diagnostic efficiency of combined detection was higher than that of single detection.
Conclusion
The expression of CST4, HPI and HER2 in serum is closely related to the depth of tumor invasion, lymph node metastasis and TNM stage. The expression of CST4, HPI and HER2 in serum can be used as an important predictor of lymph node metastasis and TNM stage in gastric cancer patients, providing a new idea for clinical diagnosis.

Objective:To understand the current status of gastroscopy in diagnosing gastric lesions in general population, and to recommend the optimal age for the first gastroscopy and intervals for repeated gastroscopy.Methods:The gastroscopy records of residents aged 18-80 years in Yinzhou District of Ningbo, Zhejiang Province, between April 2010 and December 2021 were analyzed retrospectively. The detections of gastric lesions across different years, age and genders were described. Goodness of fit tests were applied to compare the differences in detection rates of different lesions in first-time endoscopy in different age groups and different populations. Generalized additive models were used to fit the trend of age specific gastric lesion detection rate explore the optimal age for gastroscopy. The appropriate gastroscopy intervals were determined according to the progress of the gastric lesions detected in repeated gastroscopy.Results:A total of 237 751 participants with 344 398 gastroscopy records were included in analyses. A total of 5 597 cases of chronic atrophic gastritis (CAG), 9 796 cases of intestinal metaplasia (IM), 165 cases of low-grade intraepithelial neoplasia (LGIN), 52 cases of high-grade intraepithelial neoplasia (HGIN) and 435 cases of gastric cancer were detected by the first gastroscopy. The overall detection rate of gastric lesions increased significantly in age group 45-70 years, and remained stable after 70 years old, with LGIN and HGIN showing notable increases at 50 and 55 years old, respectively. Repeated gastroscopy detected CAG, IM, LGIN, and HGIN at a higher rate compared with the first gastroscopy. Normal/superficial gastritis progressed in 3-5 years, whereas CAG or more severe lesions progressed in 1-6 years.Conclusion:Gastroscopy is recommended for general population aged 45 years and above. Furthermore, gastroscopy can be performed every 3-5 years for individuals with normal endoscopy results and once a year for patients with CAG or more severe gastric lesions.

Clinical and Molecular Hepatology 2024;30(3):468-486
Background/Aims:
Chronic hepatitis C (CHC) patients who failed antiviral therapy are at increased risk for hepatocellular carcinoma (HCC). This study assessed the potential role of metformin and statins, medications for diabetes mellitus (DM) and hyperlipidemia (HLP), in reducing HCC risk among these patients.
Methods:
We included CHC patients from the T-COACH study who failed antiviral therapy. We tracked the onset of HCC 1.5 years post-therapy by linking to Taiwan’s cancer registry data from 2003 to 2019. We accounted for death and liver transplantation as competing risks and employed Gray’s cumulative incidence and Cox subdistribution hazards models to analyze HCC development.
Results:
Out of 2,779 patients, 480 (17.3%) developed HCC post-therapy. DM patients not using metformin had a 51% increased risk of HCC compared to non-DM patients, while HLP patients on statins had a 50% reduced risk compared to those without HLP. The 5-year HCC incidence was significantly higher for metformin non-users (16.5%) versus non-DM patients (11.3%; adjusted sub-distribution hazard ratio [aSHR]=1.51; P=0.007) and metformin users (3.1%; aSHR=1.59; P=0.022). Statin use in HLP patients correlated with a lower HCC risk (3.8%) compared to non-HLP patients (12.5%; aSHR=0.50; P<0.001). Notably, the increased HCC risk associated with non-use of metformin was primarily seen in non-cirrhotic patients, whereas statins decreased HCC risk in both cirrhotic and non-cirrhotic patients.
Conclusions
Metformin and statins may have a chemopreventive effect against HCC in CHC patients who failed antiviral therapy. These results support the need for personalized preventive strategies in managing HCC risk.

OBJECTIVE:
To evaluate the clinical features, laboratory and imaging results, treatment and outcomes of eosinophilic fasciitis (EF) and assess the value of ultrasound in the diagnosis of EF.
METHODS:
We retrospectively analyzed the clinical data of 45 patients with EF treated in our center from January 1, 2006 to February 28, 2022. The consistency between the diagnoses of EF based on ultrasound and MRI findings was assessed.
RESULTS:
In the 45 EF patients (male/female ratio 3.5:1), the age of onset ranged from 16 to 64 years with a mean disease course of 22.6 months. The average time from symptom onset to diagnosis was 16 months. The most common possible trigger of the disease was vigorous exercise (10/45), causing symmetrical lesions in the limbs, most commonly in the forearms (86.7%) and lower legs (80%). Clinical features of EF included subcutaneous swelling and induration (95.6%), arthralgia and arthritis (55.6%), groove sign (42.2%), hand joint contractures (42.2%), skin pigmentation (37.8%), and peau d'orange appearance (13.3%). Eosinophilia was found in 31 patients (68.9%). Hypergammaglobulinemia was seen in 23/44 (52.3%) and positive antinuclear antibodies in 9 (20%) of the patients. Twentyone of the patients were treated with high-dose methylprednisolone (≥200 mg daily for 3 to 5 consecutive days), and compared with the patients who did not receive this treatment, these patients more frequently experienced relapse before admission, had more extensive involvement, and had a higher rate of hypergammaglobulinemia without fever, but these differences were not statistically significant. Of the 31 patients (68.9%) with follow-up data (for a median of 3.2 years [range 0.2-15.9]), complete remission was achieved in 12 (38.7%) patients, and the accumulative complete remission rate was 44.1% at 5.5 years. No specific baseline characteristics or immunosuppressants were found to correlate with the treatment response. A total of 26 patients underwent both ultrasound and MRI examination, and the Kappa value of the diagnostic results between ultrasound and MRI was 0.91.
CONCLUSION
EF is characterized by symmetrical subcutaneous swelling and induration in the limbs, accompanied by eosinophilia and hypergammaglobulinemia. Glucocorticoid is effective for treating EF. Ultrasound examination can identify thickening of subcutaneous fascia for an early diagnosis of EF.

Objective: Compare and analyze the results of the domestic Lanyi AH600 glycated hemoglobin analyzer and other different detection systems to understand the comparability of the detection results of different detectors, and establish the best cut point of Lanyi AH600 determination of haemoglobin A1c (HbA1c) in the diagnosis of diabetes. Methods: Multi center cohort study was adopted. The clinical laboratory departments of 18 medical institutions independently collected test samples from their respective hospitals from March to April 2022, and independently completed comparative analysis of the evaluated instrument (Lanyi AH600) and the reference instrument HbA1c. The reference instruments include four different brands of glycosylated hemoglobin meters, including Arkray, Bio-Rad, DOSOH, and Huizhong. Scatter plot was used to calculate the correlation between the results of different detection systems, and the regression equation was calculated. The consistency analysis between the results of different detection systems was evaluated by Bland Altman method. Consistency judgment principles: (1) When the 95% limits of agreement (95% LoA) of the measurement difference was within 0.4% HbA1c and the measurement score was≥80 points, the comparison consistency was good; (2) When the measurement difference of 95% LoA exceeded 0.4% HbA1c, and the measurement score was≥80 points, the comparison consistency was relatively good; (3) The measurement score was less than 80 points, the comparison consistency was poor. The difference between the results of different detection systems was tested by paired sample T test or Wilcoxon paired sign rank sum test; The best cut-off point of diabetes was analyzed by receiver operating characteristic curve (ROC). Results: The correlation coefficient R2 of results between Lanyi AH600 and the reference instrument in 16 hospitals is≥0.99; The Bland Altman consistency analysis showed that the difference of 95% LoA in Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180) was -0.486%-0.325%, and the measurement score was 94.6 points (473/500); The difference of 95% LoA in the Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant II) was -0.727%-0.612%, and the measurement score was 89.8 points; The difference of 95% LoA in the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT) was -0.231%-0.461%, and the measurement score was 96.6 points; The difference of 95% LoA in the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT) was -0.469%-0.479%, and the measurement score was 91.9 points. The other 14 hospitals, Lanyi AH600, were compared with 4 reference instrument brands, the difference of 95% LoA was less than 0.4% HbA1c, and the scores were all greater than 95 points. The results of paired sample T test or Wilcoxon paired sign rank sum test showed that there was no statistically significant difference between Lanyi AH600 and the reference instrument Arkray HA8180 (Z=1.665,P=0.096), with no statistical difference. The mean difference between the measured values of the two instruments was 0.004%. The comparison data of Lanyi AH600 and the reference instrument of all other institutions had significant differences (all P<0.001), however, it was necessary to consider whether it was within the clinical acceptable range in combination with the results of the Bland-Altman consistency analysis. The ROC curve of HbA1c detected by Lanyi AH600 in 985 patients with diabetes and 3 423 patients with non-diabetes was analyzed, the area under curve (AUC) was 0.877, the standard error was 0.007, and the 95% confidence interval 95%CI was (0.864, 0.891), which was statistically significant (P<0.001). The maximum value of Youden index was 0.634, and the corresponding HbA1c cut point was 6.235%. The sensitivity and specificity of diabetes diagnosis were 76.2% and 87.2%, respectively. Conclusion: Among the hospitals and instruments currently included in this study, among these four hospitals included Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180), Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant Ⅱ), the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT), and the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT), the comparison between Lanyi AH600 and the reference instruments showed relatively good consistency, while the other 14 hospitals involved four different brands of reference instruments: Arkray, Bio-Rad, DOSOH, and Huizhong, Lanyi AH600 had good consistency with its comparison. The best cut point of the domestic Lanyi AH600 for detecting HbA1c in the diagnosis of diabetes is 6.235%.
