Prescription optimization is a crucial aspect in the study of traditional Chinese medicine (TCM) compounds. In recent years, the introduction of mathematical methods, data mining techniques, and artificial neural networks has provided new tools for elucidating the compatibility rules of TCM compounds. The study of TCM compounds involves numerous variables, including the proportions of different herbs, the specific extraction parts of each ingredient, and the interactions among multiple components. These factors together create a complex nonlinear dose-effect relationship. In this context, it is essential to identify methods that suit the characteristics of TCM compounds and can leverage their advantages for effective application in new drug development. This paper provided a comprehensive review of the cutting-edge optimization experimental design methods applied in recent studies of TCM compound compatibilities. The key technical issues, such as the optimization of source material selection, dosage optimization of compatible herbs, and multi-objective optimization indicators, were discussed. Furthermore, the evaluation methods for component effects were summarized during the optimization process, so as to provide scientific and practical foundations for innovative research in TCM and the development of new drugs based on TCM compounds.

Strabismus, a common ocular condition, arises from an imbalance in the extraocular muscle force and deviation of the visual axis due to various factors. Concomitant strabismus is the predominant form of exotropia, with its pathogenesis believed to be associated with hereditary factors, abnormal eye accommodation function, and anomalies in binocular anatomy. Surgical intervention is often necessary for aligning the visual axes of both eyes and facilitating the recovery and establishment of stereoscopic vision. Despite this, the etiology of concomitant exotropia remains incompletely understood. This review consolidates recent research on aberrant molecular expression and pathological morphological changes within extraocular muscles affected by concomitant exotropia, offering insights into disease causation at molecular and pathological levels to underpin future preventive measures and clinical interventions. The discussion encompasses histological changes observed under electron microscopy as well as the impact of heavy chain protein, satellite cells, cadherin, growth factors on extraocular muscle protein expression.

Uveitis is a blinding inflammatory disease that affects multiple structures within the eye, posing significant risks to patients' vision and mental health. Current treatments mainly involve glucocorticoids and immunosuppressants, which are associated with significant side effects, high relapse rates, and substantial costs. Recent research suggests that the gut microbiota may play a role in the development of uveitis through the gut-eye axis, with related metabolites also influencing disease progression. Modulating the gut microbiota or its metabolites could offer new therapeutic avenues for uveitis. This review explores the relationship between gut microbiota and various uveitis-associated diseases, such as systemic sarcoidosis, Vogt-Koyanagi-Harada syndrome, Behcet's disease, multiple sclerosis, and birdshot chorioretinopathy. It also discusses advancements in microbiota-related therapies, including probiotics and prebiotics, antibiotics, immunomodulators, phage therapy, and fecal microbiota transplantation. The aim is to provide a reference for the development of new therapies targeting specific microbial communities and genetic markers associated with uveitis, thereby promoting the realization of precision medicine.

AIM: To investigate the correlation of serum leucine-rich α-2 glycoprotein 1(LRG1)and fibroblast growth factor 21(FGF-21)levels with neovascular glaucoma(NVG).METHODS: A total of 110 cases(110 eyes)with NVG admitted to the ophthalmology department from September 2020 to September 2022 were selected as NVG group, with 23 cases of grade II, 44 cases of grade III, and 43 cases of grade IV, while 90 sex and age matched cataract patients(90 eyes)were selected as control group. The levels of LRG1, FGF-21, vascular endothelial growth factor(VEGF), pigment epithelium-derived factor(PEDF), and tumor necrosis factor-α(TNF-α)in serum were detected by ELISA; Pearson correlation analysis was used to analyze the correlation of serum LRG1 and FGF-21 levels with Teich grade, VEGF, PEDF and TNF-α levels.RESULTS: The levels of serum LRG1, FGF-21, VEGF, PEDF and TNF-α in the NVG group were significantly higher than those in the control group(all P<0.01). With the increase of Teich grading, the levels of serum LRG1, FGF-21, VEGF, PEDF and TNF-α in NVG patients significantly increased in turn(all P<0.05). Correlation analysis showed that the levels of LRG1 and FGF-21 in serum of NVG patients were positively correlated with the levels of VEGF, PEDF and TNF-α(all P<0.05).CONCLUSION: The levels of LRG1 and FGF-21 in serum of patients with NVG are obviously increased, which are positively correlated with the levels of VEGF, PEDF and TNF-α, both of which may be related to the development of NVG.

ObjectiveTo investigate the protective effect of Rehmanniae Radix iridoid glycosides (RIG) on the kidney tissue of streptozotocin (STZ)-induced diabetic mice and explore the underlying mechanism. MethodsTwelve of 72 male C57BL/6J mice were randomly selected as the normal group, and the remaining 60 mice were fed with a high-fat diet for six weeks combined with injection of 60 mg·kg-1 STZ for 4 days to model type 2 diabetes mellitus. The successfully modeled mice were randomized into model, metformin (250 mg·kg-1), catalpol (100 mg·kg-1), low-dose RIG (RIG-L, 200 mg·kg-1) and high-dose RIG (RIG-H, 400 mg·kg-1) groups (n=11). Mice in each group were administrated with corresponding drugs, while those in the normal group and model group were administrated with the same dose of distilled water by gavage once a day. After 8 weeks of intervention, an oral glucose tolerance test (OGTT) was performed, and the area under the curve (AUC) was calculated. After mice were sacrificed, both kidneys were collected. The body weight, kidney weight, and fasting blood glucose (FBG) were measured. Biochemical assays were performed to measure the serum levels of triglycerides (TG), total cholesterol (TC), serum creatinine (SCr), and blood urea nitrogen (BUN). Enzyme-linked immunosorbent assay (ELISA) was employed to determine the serum level of fasting insulin (FINS), and the insulin sensitivity index (ISI) and homeostatic model assessment for insulin resistance (HOMA-IR) were calculated. The pathological changes in kidneys of mice were observed by hematoxylin-eosin staining and Masson staining. The immunohistochemical method (IHC) was employed to assess the expression of interleukin-1 (IL-1), interleukin-6 (IL-6), tumor necrosis factor-α(TNF-α), transforming growth factor-β1 (TGF-β1), and collagen-3 (ColⅢ) in the kidney tissue. The protein levels of TGF-β1, cell signal transduction molecule 3 (Smad3), matrix metalloproteinase-9 (MMP-9), and ColⅢ in kidneys of mice were determined by Western blot. ResultsCompared with the normal group, the model group showcased decreased body weight and ISI (P<0.01), increased kidney weight, FBG, AUC, FINS, HOMA-IR, TC, TG, SCr, and BUN (P<0.01), glomerular hypertrophy, capsular space narrowing, and collagen deposition in the kidney, up-regulated protein levels of IL-1, IL-6, TNF-α, TGF-β1, ColⅢ, and Smad3 (P<0.01), and down-regulated protein level of MMP-9 (P<0.01) in the kidney tissue. Compared with the model group, the treatment groups had no significant difference in the body weight and decreased kidney weight (P<0.05, P<0.01). The FBG level declined in the RIG-H group after treatment for 4-8 weeks and in the metformin, catalpol, and RIG-L groups after treatment for 6-8 weeks (P<0.01). The AUC in the RIG-L, RIG-H, and metformin groups decreased (P<0.05, P<0.01). The levels of TC, SCr, and BUN in the serum of mice in each treatment group became lowered (P<0.05, P<0.01). The level of TG declined in the RIG-L, RIG-H, and metformin groups (P<0.05, P<0.01). The serum level of FINS declined in the catalpol, RIG-L, and metformin groups (P<0.01). Compared with the model group, the treatment groups showed decreased HOMA-IR (P<0.01), increased ISI (P<0.01), alleviated pathological changes in the kidney tissue, and down-regulated expression of IL-1 and TGF-β1. In addition, the protein levels of IL-6, TNF-α, and ColⅢ in the RIG-H and metformin groups and IL-6 and TNF-α in the RIG-L group were down-regulated (P<0.05, P<0.01), and the protein levels of IL-6, TNF-α, and ColⅢ in the catalpol group and ColⅢ in the RIG-L group showed a decreasing trend without statistical difference. The protein levels of TGF-β1, Smad3, and ColⅢ in the RIG-H and metformin groups were down-regulated (P<0.01). Compared with that in the model group, the protein level of MMP-9 was up-regulated in each treatment group (P<0.01). ConclusionRIG can improve the renal structure and function of diabetic mice by regulating the TGF-β1/Smads signaling pathway.

ObjectiveBased on literature data mining, this study explores the modeling elements of diarrhea-predominant irritable bowel syndrome (IBS-D) animal models in China and abroad, providing references and suggestions for improving modeling methods and evaluation indicators. MethodsRelevant literature on IBS-D animal experiments from 2014 to 2024 was retrieved through computer searches in databases such as China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP, Chinese Medical Journals Full-text Database, and PubMed. Information on experimental animal species, gender, body weight, modeling methods, modeling periods, intervention controls, modeling standards, and detection indicators was organized. Microsoft Excel 2021 software was used to establish a database and perform statistical analysis to examine the characteristics of IBS-D animal models. ResultsA total of 398 articles that met the inclusion criteria were reviewed. The IBS-D animal models were predominantly established using SD rats, Wistar rats, and C57BL/6 mice. Male animals were more commonly used, with rats typically aged 6-8 weeks and mice aged 4-6 weeks. In terms of interventions, piverium bromide was the main Western medicine, Tongxieyaofang was the primary Chinese medicine, and electroacupuncture was the primary acupuncture method. Among the modeling methods, the multi-factor combined composite modeling approach was the most common. Modeling periods were mainly concentrated between 1-14 days and 15-30 days. The success criteria for modeling were mainly evaluated based on the animal's general condition, fecal appearance, visceral sensitivity, gastrointestinal motility, behavior, and pathology. Detection indicators included apparent indexes, pathological markers, biochemical indicators, oxidative stress, brain-gut peptides, neurotransmitters, inflammatory factors, immune function, intestinal permeability, autophagy, apoptosis, proteins related to relevant signaling pathways, intestinal microbiota and its metabolites, etc. ConclusionThere are various methods for establishing IBS-D animal models, but no unified and universally accepted method has been established. The operation of the same modeling methods and the evaluation standards of the models vary across studies. Based on the results of data mining, the authors suggest that the multi-factor combined composite modeling approach most closely reflects the pathophysiological processes of IBS-D, better simulating the complex clinical symptoms of IBS-D patients, such as abdominal pain and diarrhea, and has a high degree of clinical relevance. This method is relatively recommended. While animal models in general align with Western medicine standards, models incorporating traditional Chinese medicine (TCM) syndromes are relatively few. Therefore, one of the future directions for research is to establish IBS-D animal models that meet the combined clinical disease and syndrome requirements of both Western and Chinese medicine.

Methods The demographic data and clinical data of breast cancer patients undergoing day (day surgery group) and ward (ward surgery group) breast conserving surgeries in West China Hospital of Sichuan University from March 2020 to June 2021 were retrospectively collected; the demographic data, clinical data, medical and related transportation costs, and preoperative and postoperative BREAST-Q scores of breast cancer patients undergoing day (day surgery group) and ward (ward surgery group) breast conserving surgery in West China Hospital of Sichuan University from June 2021 to June 2022 were prospectively collected. The safety, economic benefit, and psychological satisfaction of day surgery was analyzed. Results A total of 42 women with breast cancer were included in the retrospective study and 39 women with breast cancer were included in the prospective study. In both prospective and retrospective studies, the mean age of patients in both groups were <50 years. There were only statistical differences between the two groups in the aspects of hypertension (P=0.022), neoadjuvant chemotherapy (P=0.037) and postoperative pathological estrogen receptor (P=0.033) in the prospective study. In postoperative complications, there were no statistical differences in the surgical-related complications or anesthesia-related complications between the two groups in either the prospective study or the retrospective study (P>0.05). In terms of the overall cost, we found that the day surgery group was more economical than the ward surgery group in the prospective study (P=0.002). There were no statistical differences in postoperative psychosocical well-being, sexual well-being, satisfaction with breasts or chest condition between the two groups (P>0.05). Conclusion It is safe and reliable to carry out breast conserving surgery in day surgery center under strict management standards, which can save medical costs and will not cause great psychological burden to patients.

Objective:
To investigate the awareness of knowledge about hepatitis C prevention and control among outpatients in Ningbo City, Zhejiang Province, and its influencing factors, so as to provide the evidence for strengthening health education on hepatitis C prevention and control.
Methods:
Based on sentinel surveillance of hepatitis C, the outpatients aged 15 to 65 years at seven hospitals in Yinzhou District, Cixi City and Xiangshan County of Ningbo City were selected using the convenient sampling method from April to June during 2020 and 2022. Demographic information, knowledge and behaviors related to hepatitis C prevention and control were collected through questionnaire surveys. The influencing factors for knowledge about hepatitis C prevention and control were analyzed using a multivariable logistic regression model.
Results:
A total of 2 792 participants were surveyed, including 1 157 males (41.44%) and 1 635 females (58.56%). The awareness rate of knowledge about hepatitis C prevention and control was 56.23%, and was lower in knowledge about hepatitis C vaccine and treatment. The awareness rates of knowledge about hepatitis C prevention and control among outpatients from 2020 to 2022 were 47.11%, 53.22% and 70.65%, respectively, showing an upward trend (P<0.05). Multivariable logistic regression analysis showed that participants aged 25 to <50 years (OR=1.358, 95%CI: 1.073-1.719), with an educational level of high school or junior college (OR=1.431, 95%CI: 1.134-1.806) or above junior college (OR=3.728, 95%CI: 2.958-4.699), with household monthly income per capita of 3 000 to <5 000 yuan (OR=1.828, 95%CI: 1.344-2.486) or ≥5 000 yuan (OR=1.858, 95%CI: 1.366-2.526), without a history of invasive treatments such as pedicure in public places (OR=1.287, 95%CI: 1.024-1.618), without a history of contact with family members' blood-contaminated items (OR=2.050, 95%CI: 1.552-2.707), and always using condoms during sexual contacts (OR=1.740, 95%CI: 1.273-2.378) had higher awareness of knowledge about hepatitis C prevention and control.
Conclusions
The awareness of knowledge about hepatitis C vaccine and treatment among outpatients in Ningbo City needs to be improved. Age, educational level, household monthly income per capita, history of invasive treatments such as pedicure in public places, history of contact with family members' blood-contaminated items and frequency of condom use during sexual contacts are associated with outpatients' awareness of knowledge about hepatitis C prevention and control.

ObjectiveTo investigate the liver histopathological features of HBeAg-negative patients in the indeterminate phase of low-viral-load chronic hepatitis B virus (HBV) infection. MethodsA total of 271 patients with low-viral-load HBeAg-negative chronic HBV infection who underwent liver biopsy in Department of Infectious Diseases, Affiliated Hospital of Yan’an University, from September 2013 to June 2021 were enrolled as subjects, and the degree of liver injury was compared between patients based on age, sex, presence or absence of the family history of hepatitis B, HBsAg, and alanine aminotransferase (ALT) level. The chi-square test was used for comparison of categorical data between two groups. ResultsAmong the 271 patients with HBeAg-negative chronic HBV infection, 86 patients (31.73%) grade≥A2 liver inflammatory activity, 72 (26.57%) had a liver fibrosis stage of ive, and 112 (41.33%) had moderate or severe liver histological injury. The proportion of patients with grade≥A2 liver inflammatory activity in the patients with ALT>20 U/L was significantly higher than that in the patients with ALT≤20 U/L (χ2=3.938, P=0.047). There were no significant differences in the proportion of patients with grade≥A2 liver inflammatory activity between the patients with different ages, sexes, family history of hepatitis B, HBsAg levels (all P>0.05),there were no significant differences in the proportion of patients with a liver fibrosis stage of ≥F2 between the patients with different ages, sexes, family history of hepatitis B, HBsAg, and ALT levels (all P>0.05), and the stratified analysis of patients aged≤30 years and patients without the family history of hepatitis B showed no statistical significance between groups (all P>0.05). There was no significant difference in the degree of liver histological injury between the patients with different ages, sexes, family history of hepatitis B, HBsAg, and ALT levels (all P>0.05). ConclusionSignificant liver injury is observed in more than 40% of the patients with low-viral-load HBeAg-negative chronic HBV infection, and there is no significant difference in the degree of liver histological injury between the patients with different ages, sexes, family history of hepatitis B, HBsAg, and ALT levels. Even for the patients aged≤30 years who deny the family history of hepatitis B, there is still a considerable proportion of patients with liver injury, which should be taken seriously by clinicians.
