AIM: To compare the efficacy, safety, and complications of 27G and 25G vitrectomy in the treatment of rhegmatogenous retinal detachment(RRD)involving the macular area.METHODS:This retrospective study analyzed 60 patients(60 eyes)initially diagnosed with RRD involving the macular area and undergoing 25G or 27G vitrectomy combined with retinal reattachment at our hospital from January 2021 to December 2023. Patients were divided into 25G group(30 eyes)and 27G group(30 eyes). Best corrected visual acuity(BCVA), intraocular pressure(IOP), surgical duration, retinal reattachment rate and complications of both groups of patients were compared before and after surgery.RESULTS: The mean surgical time in the 27G group was slightly longer than in the 25G group(40.20±7.52 vs 36.97±7.47 min). Incision leakage occurred in 7 eyes(23%)in the 25G group versus 1 eye(3%)in the 27G group, though the difference was not statistically significant between two groups(P>0.05). At 6 mo postoperatively, BCVA(LogMAR)improved significantly in both groups(27G: 0.37±0.19 vs preoperative 0.98±0.32; 25G: 0.40±0.17 vs preoperative 0.84±0.33; all P<0.05), with no statistical difference in BCVA(P>0.05). At 1 d postoperatively, the 25G group had lower mean IOP(12.29±2.86 mmHg)compared to the 27G group(15.87±3.70 mmHg; P<0.001), but no differences were observed at 1 wk or 1 mo postoperatively(all P>0.05). Retinal reattachment rates and complications(intra- or postoperative)showed no significant intergroup differences(all P>0.05).CONCLUSION: Both 25G and 27G vitrectomy are safe and effective in treating rhegmatogenous retinal detachment. However, the 27G vitrectomy offers advantages such as small incisions, better self-sealing properties, and more stable IOP.

ObjectiveTo preliminarily explore the active components and target pathways of Angelicae Sinensis Radix-Polygonati Rhizoma (ASR-PR) herb pair in the treatment of simple obesity through network pharmacology and molecular docking, and to verify and investigate its mechanism of action via animal experiments. MethodsThe chemical constituents and targets of ASR and PR were predicted using the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP). Targets related to simple obesity were identified by retrieving the GeneCards, Online Mendelian Inheritance in Man (OMIM), Pharmacogenomics Knowledgebase (PharmGKB), and DisGeNET databases. The intersection of drug and disease targets was used to construct an active component-target network using Cytoscape software. This network was imported into the STRING database to construct a protein-protein interaction (PPI) network, and topological analysis was conducted to identify core genes. Gene Ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis and mapping were performed using the DAVID database and the Microbioinformatics platform. AutoDock 1.5.7 software was used to perform molecular docking between the top five active components and core targets. An animal model of simple obesity was established by feeding C57BL/6J mice a high-fat diet. The mice were administered ASR (2.06 g·kg-1), PR (2.06 g·kg-1), or ASR-PR (4.11 g·kg-1) for 10 weeks, while the model group received an equal volume of purified water by gavage. After the administration period, the mice were sacrificed to measure body fat weight and serum levels of total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL), and low-density lipoprotein (LDL). Hematoxylin-eosin (HE) staining was used to observe histopathological sections of liver and adipose tissue. Serum levels of leptin, interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) were determined by enzyme-linked immunosorbent assay (ELISA), and the mRNA expression levels of epidermal growth factor receptor (EGFR) and signal transducer and activator of transcription 3 (STAT3) in liver tissue were detected by real-time quantitative polymerase chain reaction (Real-time PCR). ResultsNetwork pharmacology and molecular docking results indicated that the treatment of simple obesity by ASR-PR may involve the regulation of protein expression of core targets EGFR and STAT3 by its main components MOL009760 (Siberian glycoside A_qt), MOL003889 (methyl protodioscin_qt), MOL009766 (resveratrol), MOL006331 (4′,5-dihydroxyflavone), and MOL004941 (baicalin), thereby modulating the PI3K/Akt and JAK/STAT signaling pathways. The animal experiment results showed that compared with the normal group, the model group had significantly increased body weight, body fat weight, and serum levels of TG, TC, TNF-α, IL-6, and leptin (P<0.01). EGFR mRNA expression was significantly elevated (P<0.05), while STAT3 mRNA expression was significantly decreased (P<0.01). Histological analysis revealed disordered hepatic architecture in the model group, with pronounced lipid vacuoles, cytoplasmic loosening, lipid accumulation, and steatosis. Adipocytes in white adipose tissue (WAT) and brown adipose tissue (BAT) of the model group exhibited markedly increased diameters, reduced cell counts per unit area, and irregular morphology. Compared with the model group, the ASR-PR group significantly reduced body weight, body fat weight, serum TC, IL-6, TNF-α, leptin levels, and EGFR mRNA expression (P<0.01). TG levels were also significantly decreased (P<0.05), while STAT3 mRNA expression was significantly increased (P<0.01). Histopathological improvements included reduced size and number of hepatic lipid vacuoles and restoration of liver cell morphology toward that of the normal group. The diameter of adipocytes significantly decreased, and the number of adipocytes per unit area increased. ConclusionASR-PR may regulate the expression of key target proteins such as EGFR and STAT3 via its core active components, modulate the PI3K/Akt and JAK/STAT signaling pathways, repair damaged liver and adipose tissues, and thereby alleviate the progression of obesity in mice.

ObjectiveTo investigate the different effects of Yunvjian with or without Achyranthis Bidentatae Radix on glucose and lipid metabolism and inflammatory response in diabetic rats with the syndrome of Yin deficiency and internal heat. MethodThe rat model of diabetes due to Yin deficiency and internal heat was established by feeding with a high-sugar and high-fat diet and injection of thyroxine and streptozotocin. The successfully modeled rats were randomized into model control, Yunvjian without Achyranthis Bidentatae Radix (11.8 g·kg-1), Yunvjian with Achyranthis Bidentatae Radix (12.8 g·kg-1), and Achyranthis Bidentatae Radix (1.0 g·kg-1) groups (n=10), and another 10 rats were taken as the normal control group. Each group was administrated with corresponding drugs or saline by gavage for 28 days. The fasting blood glucose (FBG), fasting insulin (FINS), total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) in rats were measured. Enzyme-linked immunosorbent assay was employed to determine the levels of cyclic adenosine monophosphate (cAMP), cyclic guanosine monophosphate (cGMP), triiodothyronine (T3), thyroxine (T4), interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF)-α, and C-reactive protein (CRP) in the serum. The histopathological changes of the liver were observed. The expression of lipoxygenase-2 (COX-2) was detected by immunofluorescence. The mRNA levels of nuclear transcription factors-κB (NF-κB), monocyte chemotactic protein-1 (MCP-1), and intercellular adhesion molecule-1 (ICAM-1) were determined by real-time polymerase chain reaction (Real-time PCR).Western blot was employed to determine the protein levels of NF-κB in hibitory protein(IκB) kinase β (IKKβ), IκBα, and phosphorylated IκBα (p-IκBα) in the liver and the protein levels of NF-κB in the cytoplasm and nucleus. ResultCompared with the normal group, the model group showed elevated levels of FBG, FINS, insulin resistance index, TC, TG, LDL-C, cAMP, T3, T4, IL-1β, IL-6, TNF-α, and CRP, up-regulated mRNA levels of NF-κB, MCP-1, and ICAM-1, and up-regulated protein levels of COX-2, p-IκBα, and nuclear NF-κB (P<0.01). Compared with the model group, Yunvjian without Achyranthis Bidentatae Radix lowered the levels of FBG, FINS, insulin resistance index, TC, TG, LDL-C, cAMP, T3, T4, IL-1β, IL-6, TNF-α, and CRP, down-regulated the mRNA levels of NF-κB, MCP-1, and ICAM-1, and down-regulated the protein levels of COX-2, p-IκBα and nuclear NF-κB (P<0.05, P<0.01). Compared with the Yunvjian without Achyranthis Bidentatae Radix, Yunvjian with Achyranthis Bidentatae Radix showed lowered levels of FBG, FINS, insulin resistance index, and inflammatory cytokines, down-regulated mRNA levels of NF-κB, MCP-1, and ICAM-1, and down-regulated protein levels of p-IκBα and nuclear NF-κB (P<0.05, P<0.01). ConclusionAchyranthis Bidentatae Radix can enhance the performance of Yunvjian in reducing blood glucose and inhibiting inflammation in diabetic rats with the syndrome of yin deficiency and internal heat by down-regulating the IKK/IκB/NF-κB signaling pathway.

ABATRACT
OBJECTIVE To utilize the pharmacophore model-molecular docking combined with the virtual screening strategy of free energy calculation and the chemical bioinformatics method of traditional Chinese medicine in cell biology experiments to investigate the components of Guiqi Baizhu prescription that target phosphatidylinositol 3-kinase(PI3K) and inhibit the proliferation of uveal melanoma(UM) cells.
METHODS The pharmacophore model of PI3K inhibitor was constructed, and the compounds of Guiqi Baizhu prescription were virtual screened. The components that fit the pharmacophore model were calculated by molecular docking and binding free energy, and the potential inhibitory components were selected for biological experimental evaluation. The effects of potential inhibitory components on UM cell proliferation were detected by CCK-8 and clonal formation assay. Flow cytometry was used to detect the cell cycle and apoptosis of UM cells. The mitochondrial membrane potential of UM cells was detected using JC-10 staining. The expressions of PI3K and downstream pathway proteins were detected by Western blotting.RESULTS The pharmacophore model included 2 hydrogen bond receptors, 2 aromatic ring centers, and exclusion volumes. The results of the CCK-8 experiment showed that quercetin, tangerine, and nobiletin at concentrations of 10, 20, 40, 80 μmol·L−1, and cyrtin at concentrations of 20, 40, 80 μmol·L−1, were able to inhibit the proliferation of UM cells. The clonal formation experiment showed that quercetin, tangerine, nobiletin, and morusin, at different concentrations, could significantly inhibit the clonal proliferation of UM cells. Flow cytometry showed that UM cells were arrested in the G0/G1 phase by tangeretin and quercetin, while UM cells were arrested in the G2/M phase by nobiletin and morusin. The results of JC-10 staining showed that quercetin, nobiletin, tangeretin, and morusin could reduce the mitochondrial membrane potential of UM cells. Western blotting results showed that 4 compounds could target PI3K, but their downstream pathways were different.CONCLUSION Based on the method of chemical bioinformatics in traditional Chinese medicine, this study explores the material basis for the inhibition of UM cell proliferation by the Guiqi Baizhu prescription. It also provides insights for the modern development of traditional Chinese medicine prescription.

METHODS Establishment of rat RA model using bovine type Ⅱ collagen and Freund’s complete adjuvant. The model rats were randomly divided into model group and low-dose, middle-dose and high-dose groups (55, 110, 220 mg/kg) of petroleum ether extract of S. divaricata; the normal group without modeling was also established, with 10 rats in each group. Each group was given corresponding drugs or constant volume of 2% Tween-80 solution intragastrically, once a day, for consecutive 28 days. The toe swelling degree in rats was observed, and the arthritis index (AI) was scored. The serum levels of interleukin-1β (IL-1β), IL-10, IL-17, tumor necrosis factor-α (TNF-α), 25-hydroxyvitamin D3 [25(OH)D3], myeloperoxidase (MPO), neutrophil elastase (NE) and NETs in rats were detected. The histopathological changes in ankle joint were observed. The expression of citrullinated histone H3 (CitH3) in ankle joint as well as the expressions of cytochrome P450 24A1 (CYP24A1), cytochrome P450 27B1 (CYP27B1),vitamin D receptor (VDR) and peptidyl arginine deiminase 4 疾病。E-mail:zhongyao626@126.com (PAD4) in synovium were all determined. RESULTS Compared with the model group, the toe swelling degree and AI score in the middle-dose and high-dose groups of petroleum ether extract of S. divaricata decreased significantly from day 14 to day 28 after administration (P<0.05 or P<0.01). The serum levels of IL-1β, IL-17, TNF-α, MPO, NE and NETs decreased significantly, while the levels of IL-10 and 25(OH)D3 increased significantly (P<0.05 or P<0.01). The widened ankle joint space and the improved structure were found; the expression of CitH3 in ankle joint, and the expressions of CYP24A1 and PAD4 in synovium were down-regulated significantly, while the expressions of CYP27B1 and VDR were up-regulated significantly in synovium (P<0.05 or P<0.01). CONCLUSIONS The petroleum ether extract of S. divaricata may inhibit the production of NETs and improve the symptoms of RA by regulating the vitamin D system.

OBJECTIVE
To explore the effectiveness, potential mechanism and compatibility characteristics of efficacy groups of Dunhuang medical prescription Daxiefei decoction in preventing and treating pneumonia based on chemical bioinformatics method.
METHODS
To study the effect of Daxiefei decoction freeze-dried powder solution on the proliferation activity of lung epithelial cells through cell experiments. Daxiefei decoction was divided into three groups: clearing away heat group, resolving phlegm group, and nourishing Yin group according to its efficacy characteristics. The chemical components of Daxiefei decoction were obtained by TCMSP database and literature search, and the targets were predicted in Swiss Target Prediction database. Pneumonia disease targets were obtained by DrugBank, TTD, Genecards and DisGeNET databases. STRING database and Cytoscape were used to construct the intersection target interaction network and "drug-component-target- pathway" network and DAVID database was used for KEGG pathway enrichment analysis. The network was used to analyze the scientific connotation of the compatibility of efficacy groups. Furthermore, molecular docking was used to evaluate the target-compound affinity and molecular dynamics was used to explore the dynamic molecular mechanism.
RESULTS
Cell experiments showed that Daxiefei decoction can maintain the proliferation of lung epithelial cells, reverse the decrease of mitochondrial activity induced by LPS and reduce apoptosis. Complex network analysis showed that the pathways enriched by the three functional groups contained in Daxiefei decoction were mainly distributed in two modules: inflammation regulation and reducing airway mucus hypersecretion. Each module was connected by a common target gene and had its own focus. The results of molecular docking showed that the components quercetin, baicalein, isorhamnetin etc. might be the effective multi-target components of Daxiefei decoction. SRC, EGFR, PPARA etc. had good affinity with each potential active component, which might be a potential target of Daxiefei decoction for preventing and treating pneumonia. Molecular dynamics simulation showed that the potential active component quercetin formed stable intermolecular interactions with SRC.
CONCLUSION
This study initially reveal the material basis and molecular mechanism of Daxiefei decoction in the prevention and treatment of pneumonia. It also explores the scientific connotation of Daxiefei decoction in the prevention and treatment of pneumonia with different efficacy groups, and its modern development and clinical application provide chemical bioinformatics basis.

Objective:To explore the prognostic factors associated with clear cell adenocarcinoma (CCAC) of the uterine cervix based on data in the Surveillance, Epidemiology and End Results (SEER) database.Methods:Clinical data were collected from 431 patients with confirmed CCAC in the SEER database from 1976 to 2017. Survival analysis was performed using the Kaplan-Meier method with log-rank test for comparison between subgroups. Cox proportional hazards model was used to analyze the influencing factors of overall survival (OS).Results:The median age [ M ( Q1, Q3)] of 431 patients was 54 years old (40 years old, 71 years old); there were 333 cases (77.3%) of whit. The median OS time of 431 patients was 93 months (95% CI: 47-148 months), and the 1-, 2-, and 5-year OS rates were 80.1%, 65.8% and 54.2%, respectively. The median OS time was not reached in patients with American Joint Committee on Cancer (AJCC) stage Ⅰ, 83 months (95% CI: 21-144 months) for stage Ⅱ, 32 months (95% CI: 16-47 months) for stage Ⅲ, and 9 months (95% CI: 5-13 months) for stage Ⅳ ( P < 0.001). Median OS time was not reached in patients with SEER stage of localized lesions, 46 months (95% CI: 8-83 months) for regional lesions stage, and 9 months (95% CI: 5-12 months) for distant metastases stage ( P < 0.001). Of the patients with clear AJCC staging and some with unspecified AJCC staging, 118 received surgical treatment alone and 119 received postoperative radiotherapy, the median OS time of the two groups was 443 months (95% CI: 162-723 months) and 102 months (95% CI: 75-129 months), and the difference in OS between the two groups was statistically significant ( P < 0.001). Among the patients with AJCC stage Ⅰ, the 5-year OS rates in surgery-only group and postoperative radiotherapy group were 82.5% and 78.5%, the stage Ⅱ were 80.0% and 52.3%, and the stage Ⅲ were 27.8% and 63.3%, respectively; the differences in OS between different stages were not statistically significant (all P>0.05). Among the patients with SEER localized lesions stage, the 5-year OS rates in surgery-only group and postoperative radiotherapy group were 88.9% and 73.1%, and the difference was statistically significant ( P = 0.012); the regional lesions stage were 45.5% and 60.0%, and the difference was not statistically significant ( P = 0.568). The results of multivariate Cox regression analysis showed that AJCC staging (stage Ⅰ vs. stage Ⅳ, HR = 0.281, 95% CI: 0.178-0.543, P < 0.001; stage Ⅱ vs. stage Ⅳ, HR = 0.347, 95% CI: 0.113-0.439, P < 0.001; stage Ⅲ vs. stage Ⅳ, HR = 0.399, 95% CI: 0.030-0.145, P < 0.001), SEER staging (localized lesions stage vs. distant metastases stage, HR = 0.104, 95% CI: 0.059-0.182, P < 0.001; regional lesions stage vs. distant metastases stage, HR = 0.301, 95% CI: 0.195-0.463, P < 0.001) and whether or not receive surgery (yes vs. no, HR = 0.359, 95% CI: 0.241-0.535, P < 0.001) were independent influencing factors of OS in CCAC patients. Conclusions:AJCC staging, SEER staging and surgery are independent influence factors for OS in patients with CCAC, and postoperative radiotherapy may not provide more survival benefit.
