ObjectiveThrough qualitatively and quantitatively analysis of the differences in chemical composition between the combined decoction and single decoction of Huaganjian and comparison of their core efficacy， to explore the rationality of the flexible clinical application of Huaganjian compound preparations and single-flavored dispensing granules. MethodsUltra performance liquid chromatography-quadrupole-electrostatic field orbitrap high resolution mass spectrometry（UPLC-Q-Exactive Orbitrap MS） was used to qualitatively analyze the combined decoction and single decoction samples of Huaganjian， and meanwhile， the contents of four index components（geniposide， paeoniflorin， hesperidin and paeonol） were quantitatively analyzed by high performance liquid chromatography（HPLC）. Nonalcoholic fatty liver disease（NAFLD） rat model induced by high-fat diet was applied to compare the efficacy of combined decoction and single decoction of Huaganjian. A total of 30 male SD rats were randomly divided into the control group， model group， lovastatin group（1.8 mg·kg^-1）， combined decoction group（1.26 g·kg^-1） and single decoction group（1.18 g·kg^-1）. After successful modeling， lovastatin group， combined decoction group and single decoction group were given corresponding doses of drugs by intragastric administration every day， and the control group and model group were given equal amounts of normal saline by intragastric administration， after 4 weeks of administration， the serum and liver tissues were collected， and the contents of alanine aminotransferase（ALT）， aspartate aminotransferase（AST）， total cholesterol（TC）， triglyceride（TG）， low-density lipoprotein cholesterol（LDL-C） and high-density lipoprotein cholesterol（HDL-C） in serum of rats were detected， and the liver pathological examination was carried out by hematoxylin-eosin（HE） staining and oil red O staining， so as to compare differences of their efficacy. ResultsSeventy chemical components were initially identified and attributed from the lyophilized powder of the combined decoction and single decoction samples of Huaganjian， and there was no obvious difference in composition between the two. Further quantitative analysis showed that the contents of geniposide， paeoniflorin， hesperidin and paeonol in the combined decoction samples were significantly increased when compared with those of the single decoction samples（P<0.01）. The pharmacodynamic results showed that compared with the model group， both the combined and single decoction groups of Huaganjian could improve the liver index of NAFLD rats， reduce the serum levels of AST， ALT， TC， TG and LDL-C， increase the serum level of HDL-C， and ameliorate the pathological changes of liver cell steatosis and fat accumulation. However， there was no significant difference in pharmacodynamic effects between the combined decoction group and the single decoction group. ConclusionThere is no significant difference between the combined decoction and single decoction of Huaganjian in terms of chemical composition， but the contents of the four index components show significantly difference. Both of them can significantly improve the fat accumulation and liver function in NAFLD rats. This study provides a reference basis for the rational clinical application and evaluation of famous classical formula compound preparations and single-flavored dispensing granules.

Objective To analyze the clinical characteristics and high risk factors of prognosis in patients with chronic heart failure and renal insufficiency. Methods A total of 499 patients with chronic heart failure and renal insufficiency from September 2022 to September 2024 were selected. The clinical data of patients were collected, and the clinical characteristics were analyzed. After 3 months of follow-up, the patients were divided into survival group and death group according to the prognosis status. Univariate analysis, and multivariate logistic regression analysis were adopted to analyze the risk factors affecting the prognosis of patients. Results According to different ejection fraction values, patients were classified into HFrEF group (n=164), HFmrEF group (n=103) and HFpEF group (n=232). The age in HFpEF group was the lowest (P<0.05). The cardiac function grading was the highest in HFrEF group, and the systolic blood pressure was lower while the diastolic blood pressure was higher than that in the other two groups (P<0.05), and there were no differences in cardiac function, systolic blood pressure and diastolic blood pressure between HFmrEF group and HFpEF group (P>0.05). The levels of Hb and ALB in HFpEF group were higher than those in HFrEF group (P<0.05), and no differences were observed between HFmrEF group and the other two groups (P>0.05). HFrEF group had the lowest total cholesterol and Scr, and the highest serum uric acid, eGFR, BNP and cTnI (P<0.05). The level of hs-CRP in HFmrEF group was the lowest. The LVEDD was lower in HFpEF group than that in the other two groups (P<0.05). The levels of serum uric acid, Scr and hs-CRP in death group were higher while the eGFR was lower compared to survival group (P<0.05). After logistic analysis, it was found that elevated levels of serum uric acid and hs-CRP and decreased eGFR were risk factors for poor prognosis (P<0.05). Conclusion Patients with chronic heart failure and renal insufficiency are mainly HFpEF. Elevated serum uric acid and hs-CRP and decreased eGFR are the high risk factors for poor prognosis.

ObjectiveTo explore the potential therapeutic targets and molecular mechanisms of menstrual blood-derived stem cells (MenSCs) transplantation combined with exercise training in promoting recovery in rats with spinal cord injury (SCI) through transcriptome sequencing analysis. MethodsFemale SD rats aged two months were selected and a SCI model was established by a hemisection at the tenth thoracic vertebra (T10). The rats were then divided into two groups: the Cell and Treadmill Training (CTMT) group, which received MenSCs transplantation and treadmill training after SCI, and the SCI group (control), with 12 rats in each group. One week after modeling, the CTMT group received a microinjection of 1×10⁵ MenSCs at the injury site, followed by two weeks of weight-supported aerobic exercise training. Spinal cord tissue from the injury site was selected for transcriptome sequencing, and mRNA expression data from both the SCI and CTMT groups were analyzed. Differential gene expression, GO (Gene Ontology) functional enrichment, KEGG (Kyoto Encyclopedia of Genes and Genomes) pathway enrichment, and protein-protein interaction (PPI) network analyses were performed. Motor function recovery was assessed using the Basso, Beattie, and Bresnahan (BBB) score, while histopathological changes at the injury site were evaluated through hematoxylin-eosin (HE) staining. Real-time fluorescent quantitative PCR and Western blotting were used to verify the expression of differentially expressed genes. ResultsTranscriptome sequencing analysis showed 247 upregulated genes and 174 downregulated genes in the CTMT group compared to the SCI group. Notably, genes such as Bdnf, Hmox1, Sd4, Mmp3, and Cd163 were significantly upregulated [|log2(FoldChange)|≥0.66, P<0.05]. KEGG pathway enrichment analysis and GO functional enrichment analysis indicated that these differentially expressed genes were mainly involved in growth and development, metabolic reactions, and immune-inflammatory processes, such as axon growth and the electron transport chain. The Bdnf gene was notably enriched in the PI3K-Akt signaling pathway. The BBB score showed that MenSCs transplantation combined with exercise training significantly improved the motor function of SCI rats. HE staining revealed that pathological changes at the injury site were significantly reduced in the treatment group. Furthermore, real-time quantitative PCR and Western blotting confirmed that brain-derived neurotrophic factor (BDNF) mRNA and protein expression levels in the CTMT group were significantly higher than those in the SCI group (P<0.001). ConclusionThe combined exercise training with MenSCs effectively promotes the recovery of motor function in SCI rats by upregulating BDNF expression, providing a novel strategy for SCI treatment.

Objective:To compare the chemical composition of decoction and granules of Sangju Decoction; To provide a method for quality evaluation of Sangju Decoction.Methods:HPLC was used to establish fingerprints, and a comprehensive comparative study was conducted on the traditional decoction and formula granules of Sangju Decoction from four aspects: chemical composition type, fingerprint similarity, chemical pattern recognition analysis, and representative index component content.Results:The fingerprint similarity of the 10 batches of traditional decoction was >0.988. 35 peaks were identified and 12 peaks were identified as common peaks (neochlorogenic acid for peak 7, chlorogenic acid for peak 10, cryptochlorogenic acid for peak 11, 1,3-dicaffeoylquinic acid for peak 13, rutin for peak 17, lenoside A for peak 19, lignan for peak 20, isochlorogenic acid B for peak 24, ammonium glycyrrhizate for peak 25). The fingerprint similarity of the formulation pellets was >0.983, and 29 characteristic peaks were identified. Compared with the traditional decoction, some batches of the granules lacked peaks 14, 26, 27, 30, 32 and 34, and clustering analysis (CA), principal component analysis (PCA), and orthogonal partial least squares discriminant analysis (OPLS-DA) could distinguish between the two. The contents of the 10 index components neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, 1,3-dicaffeoylquinic acid, forsythia ester glycoside A, grass glycosides, isochlorogenic acid B, 3,5-O-dicaffeoylquinic acid, forsythia glycosides, monkshood glycosides in the traditional soup were higher than that in the granules, and the contents of rutin and ammonium glycyrrhizate in the granules were higher than that in traditional decoction.Conclusions:The content and composition of traditional decoction and formula granules of Sangju Decoction are significantly different. The combination of fingerprinting and chemical pattern identification effectively can effectively evaluate the difference between traditional decoction and formula granules of Sangju Decoction, which can lay a foundation for the quality control and rational clinical application of formula granules of Sangju Decoction.

ObjectiveThis paper aims to analyze the current status of outcome indicators in randomized controlled trials （RCT） of traditional Chinese medicine （TCM） for treating chronic atrophic gastritis （CAG）， so as to provide references for constructing the core outcome set （COS） of TCM in the treatment of CAG. MethodChina National Knowledge Infrastructure （CNKI）， Wanfang， VIP， SinoMed， PubMed， Embase， and Cochrane Library databases were searched for RCTs of TCM in the treatment of CAG in the last five years. The risk of bias of included studies was evaluated， and the selection status of outcome indicators was statistically analyzed. ResultA total of 150 RCTs were included， with a sample size of 44-398 cases. 164 outcome indicators were reported， with an application frequency of 1 229 times. The outcome indicators were classified into seven indicator domains according to functional attributes， followed by physical and chemical examination （69.41%）， TCM syndrome （12.69%）， symptoms and signs （11.15%）， safety indicators （5.37%）， quality of life （0.65%）， long-term prognosis （0.65%）， and economic evaluation （0.08%）. According to the statistical analysis， there were problems in the selection of outcome indicators in RCTs of TCM for treating CAG， including various indicators， non-standard name reports， unclear primary and secondary indicators， random combination of subjective and objective indicators， neglected patient report outcome indicators， missing long-term prognosis and economic indicators， insufficient reporting of safety indicators， and inconsistent measurement tools and measurement time points. ConclusionIn the past five years， there have been many problems in the selection of outcome indicators in RCTs of TCM for treating CAG. It is necessary to actively promote the construction of the COS of TCM in the treatment of CAG and promote the high-quality development of clinical research of TCM.

This review aims to summarize the roles of m6A methylation modification in ocular cells and ocular diseases, elucidate the potential molecular mechanisms of m6A methylation in ocular diseases, so as to encourage innovative approaches in the treatment of these ocular diseases.

Objective:To establish and verify a diagnostic model for distinguishing multiple sclerosis (MS) from other neurological diseases with similar symptoms by usingcerebrospinal fluid oligoclonal band (CSF-OCB)combined with IgG intrathecal synthesis indicators and biochemical markers.Methods:Multiple sclerosis (MS) patients admitted to the Neurology Department of Beijing Tiantan Hospital affiliated with Capital Medical University from January 2014 to December 2022 were selected as the case group, while patients with similar neurological symptoms were selected as the control group. Using the case-control study design, a retrospective analysis was conducted on the detection of age, gender, oligoclonal bands in cerebrospinal fluid, IgG intrathecal synthesis indicators and biochemical indicators for all study subjects. The differential diagnosis model was determined by the multiple logistic regression analysis, and the receiver operating characteristic (ROC) curve was used to analyze the diagnostic efficiency of the differential diagnosis model for neurological diseases with similar symptoms to MS and other conditions.Results:This study included 167 patients in the case group and 335 patients in the control group, of which 128 patients in the case group and 265 patients in the control group were used to construct the model, and 39 patients in the case group and 70 patients in the control group were used for model validation. The differential diagnostic model constructed by a multivariate logistic regression model was Y=0.871×CSF-OCB-0.051×CSFprotein-0.231×CSFchloride+1.183×gender-0.036×LDH+35.770. The model showed that the area under the curve, sensitivity and specificity were respectively 0.916, 87.3% and 87.6%. The Delong test results showed that the diagnostic efficacy of the model was significantly different from OCB, IgG intrathecal synthesis indicators, and OCB combined with IgG intrathecal synthesis indicators ( P<0.05). The new model validation showed that the actual diagnostic consistency rate for the MS group was 84.6%, while the actual diagnostic consistency rate for the control group was 90.0%. Conclusion:This study combines OCB, IgG intrathecal synthesis indicators, and biochemical indicators to establish a diagnostic prediction model for neurological diseases with similar clinical symptoms in MS. This model may have good differential diagnostic value and can better assist clinical diagnosis in the early stages of disease progression in MS patients.

Efforts have been made to establish various human pluripotent stem cell lines. However, such methods have not yet been duplicated in non-human primate cells. Here, we introduce a multiplexed single-cell sequencing technique to profile the molecular features of monkey pluripotent stem cells in published culture conditions. The results demonstrate suboptimized maintenance of pluripotency and show that the selected signaling pathways for resetting human stem cells can also be interpreted for establishing monkey cell lines. Overall, this work legitimates the translation of novel human cell line culture conditions to monkey cells and provides guidance for exploring chemical cocktails for monkey stem cell line derivation.

Diarrhea-predominant irritable bowel syndrome （IBS-D） is a chronic functional bowel disorder characterized by abdominal pain and diarrhea， with visceral hypersensitivity and abnormal gastrointestinal dynamics as the pathophysiological basis. The brain-gut interaction plays a role in pain-related functional gastrointestinal disorders， especially IBS-D. 5-Hydroxytryptamine （5-HT）， as an important brain-gut peptide regulating gastrointestinal function， affects brain activity， gastrointestinal motility， pain perception， mucosal inflammation， and immune response through brain-gut interaction and is associated with the occurrence and development of IBS-D. In recent years， traditional Chinese medicine （TCM） has shown great potential to mitigate gastrointestinal symptoms and improve the quality of life with its holistic view and treatment based on syndrome differentiation. Studies have shown that TCM treats IBS-D by regulating the 5-HT signaling pathway. With a focus on syndrome differentiation in TCM， this paper systematically describes the efficacy and mechanism of TCM in treating different TCM syndromes of IBS-D via the 5-HT signaling pathway， aiming to provide a scientific basis for TCM treatment of this disease.
