Traditional Chinese medicine （TCM） therapy has unique clinical advantages in the treatment of atrial fibrillation， mainly reflected in five aspects， improving quality of life， enabling early diagnosis and treatment， promoting cardiac rehabilitation， making up for the limitations of Western medicine， and improving the success rate of catheter ablation. However， there is insufficient evidence in current clinical research. Based on the current status of TCM research in the treatment of atrial fibrillation， it is suggested that future studies should focus on standardized research on syndrome differentiation and classification. This can be achieved through clinical epidemiological surveys， expert consensus， and other methods to establish a unified syndrome differentiation and classification standard for atrial fibrillation. Clinical efficacy evaluation indicators should be standardized， and core outcome measures for clinical research on TCM treatment of atrial fibrillation should be developed through systematic reviews， patient interviews， and other methods. Additionally， clinical research design， implementation， and data management should be improved. By leveraging modern information technologies such as artificial intelligence， the scientific and standardized nature of TCM intervention research on atrial fibrillation can be enhanced， ultimately improving the quality of research.

[Objective] To explore the predictive value of HALP score for prognosis in patients with multiple myeloma (MM). [Methods] A retrospective analysis was conducted on laboratory indicators and related clinical data of newly diagnosed multiple myeloma (NDMM) patients, treated at the Affiliated Hospital of North Sichuan Medical College from January 2016 to October 2023, prior to their first treatment. The HALP score was calculated, and the optimal cutoff value for HALP was determined using X-tile software. Survival analysis was performed using Kaplan-Meier curves for high HALP and low HALP groups. Univariate and multivariate analyses were conducted using the Cox regression model, and a forest plot was generated using Graphpad Prism to illustrate factors that may impact patient prognosis. The predictive ability of HALP score combined with β2-microglobulin and ECOG score for prognosis in MM patients was evaluated using receiver operating characteristic curve (ROC) analysis. [Results] A total of 203 MM patients were included, with the optimal cutoff value for HALP score being 29.15 (P<0.05). Among them, 101 patients were in the low HALP score group, and 102 patients were in the high HALP score group. The results of univariate and multivariate analysis using the Cox regression model showed that a HALP score <29.15 was an independent risk factor for progression-free survival (PFS) and overall survival (OS) (P<0.05). ROC curve analysis indicated that the combination of HALP score with β2-microglobulin and ECOG score had a higher predictive value for prognosis in MM patients compared to using HALP score alone. [Conclusion] The HALP score is closely related to the prognosis of patients with NDMM. A low HALP score indicates a poorer prognosis, while the combination of HALP score with β2-microglobulin and ECOG score provides a higher predictive value when assessed together.

OBJECTIVE To optimize the simmering technology of Rheum palmatum from Menghe Medical School and compare the difference of chemical components before and after processing. METHODS Using appearance score， the contents of gallic acid， 5-hydroxymethylfurfural （5-HMF）， sennoside A+sennoside B， combined anthraquinone and free anthraquinone as indexes， analytic hierarchy process （AHP）-entropy weight method was used to calculate the comprehensive score of evaluation indicators； the orthogonal experiment was designed to optimize the processing technology of simmering R. palmatum with fire temperature， simmering time， paper layer number and paper wrapping time as factors； validation test was conducted. The changes in the contents of five anthraquinones （aloe-emodin， rhein， emodin， chrysophanol， physcion）， five anthraquinone glycosides （barbaloin， rheinoside， rhubarb glycoside， emodin glycoside， and emodin methyl ether glycoside）， two sennosides （sennoside A， sennoside B）， gallic acid and 5-HMF were compared between simmered R. palmatum prepared by optimized technology and R. palmatum. RESULTS The optimal processing conditions of R. palmatum was as follows: each 80 g R. palmatum was wrapped with a layer of wet paper for 0.5 h， simmered on high heat for 20 min and then simmered at 140 ℃， the total simmering time was 2.5 h. The average comprehensive score of 3 validation tests was 94.10 （RSD＜1.0%）. After simmering， the contents of five anthraquinones and two sennosides were decreased significantly， while those of 5 free anthraquinones and gallic acid were increased to different extents； a new component 5-HMF was formed. CONCLUSIONS This study successfully optimizes the simmering technology of R. palmatum. There is a significant difference in the chemical components before and after processing， which can explain that simmering technology slows down the relase of R. palmatum and beneficiate it.

Background::Heterotaxy (HTX) is a thoracoabdominal organ anomaly syndrome and commonly accompanied by congenital heart disease (CHD). The aim of this study was to analyze rare copy number variations (CNVs) in a HTX/CHD cohort and to examine the potential mechanisms contributing to HTX/CHD.Methods::Chromosome microarray analysis was used to identify rare CNVs in a cohort of 120 unrelated HTX/CHD patients, and available samples from parents were used to confirm the inheritance pattern. Potential candidate genes in CNVs region were prioritized via the DECIPHER database, and PNPLA4 was identified as the leading candidate gene. To validate, we generated PNPLA4-overexpressing human induced pluripotent stem cell lines as well as pnpla4-overexpressing zebrafish model, followed by a series of transcriptomic, biochemical and cellular analyses. Results::Seventeen rare CNVs were identified in 15 of the 120 HTX/CHD patients (12.5%). Xp22.31 duplication was one of the inherited CNVs identified in this HTX/CHD cohort, and PNPLA4 in the Xp22.31 was a candidate gene associated with HTX/CHD. PNPLA4 is expressed in the lateral plate mesoderm, which is known to be critical for left/right embryonic patterning as well as cardiomyocyte differentiation, and in the neural crest cell lineage. Through a series of in vivo and in vitro analyses at the molecular and cellular levels, we revealed that the biological function of PNPLA4 is importantly involved in the primary cilia formation and function via its regulation of energy metabolism and mitochondria-mediated ATP production. Conclusions::Our findings demonstrated a significant association between CNVs and HTX/CHD. Our data strongly suggested that an increased genetic dose of PNPLA4 due to Xp22.31 duplication is a disease-causing risk factor for HTX/CHD.

Objective:To evaluate pulmonary hypertension (PH) in Chinese people living with human immunodeficiency virus (HIV) receiving long-term anti-retroviral therapy (ART) and those who had not received ART for HIV infection, and to analyze the risk factors for PH in HIV infected individuals, so as to provide evidence for the monitoring and management of cardiovascular diseases in people living with HIV in China.Methods:HIV infected individuals who received long-term ART were from the NCT04463810 study cohort. In addition, using propensity score matching method, gender matched HIV infected individuals who had not received ART were selected as controls from the NCT00872417 and NCT01844297 studies. This study was a retrospective and observational clinical study. Basic data, clinical visit and cardiac Doppler ultrasonography data were collected to analyze the prevalence of PH and risk factors for PH in people living with HIV. Chi-square test and multivariate logistic regression were used for statistical analysis.Results:Among the 318 HIV infected individuals, 159 underwent long-term ART and 159 did not receive ART, which were divided into long-term ART group and ART-na?ve group, respectively. Among 318 HIV infected individuals, 30 cases (9.4%) experienced PH, including 23 cases (7.2%) with critical PH, six cases (1.9%) with mild PH, one case (0.3%) with moderate PH, and there was no severe PH. The prevalence of PH in the long-term ART group was 5.0%(8/159), which was lower than that in the ART-na?ve group (13.8%, 22/159). The difference was statistically significant ( χ2=7.21, P=0.012). Multivariate analysis showed that older age (odds ratio ( OR)=1.064, 95% confidence interval ( CI) 1.019 to 1.111, P=0.016) and unsuppressed HIV status ( OR=2.660, 95% CI 1.041 to 6.797, P=0.041) were independent risk factors for PH of people living with HIV. Conclusions:The prevalence of PH in people living with HIV with long-term ART is lower than that of ART-na?ve people living with HIV. Older age and unsuppressed HIV status are independent risk factors for PH in people living with HIV. Cardiac Doppler ultrasonography is helpful for the early screening of PH in people living with HIV. ART should be actively performed to reduce the incidence of PH in people living with HIV.

ObjectiveTo analyze the correlation between 11 small molecule active components and 1 protein component of characteristic processed products with porcine cardiac blood and other products of Salviae Miltiorrhizae Radix et Rhizoma（SMRR） from Menghe medical school and anti-cerebral ischemic oxidative damage， and to identify its key component markers of characteristic processed products with porcine cardiac blood for anti-cerebral ischemic oxidative damage. MethodHigh performance liquid chromatography（HPLC） was established to simultaneously determine the contents of 11 active ingredients in SMRR and its processed products［processed with porcine cardiac blood， porcine blood， wine and transferrin（Tf） in porcine cardiac blood］， and the content of Tf in different processed products of SMRR was detected by enzyme-linked immunosorbent assay（ELISA）. Furthermore， A zebrafish ischemic stroke model was constructed to evaluate the effects of different processed products of SMRR on the behavioral trajectory of cerebral ischemic zebrafish， the neuronal damage of transgenic zebrafish Tg（elavl3：eGFP） brain， as well as the levels of malondialdehyde（MDA） and superoxide dismutase（SOD） in the brain tissues. The hippocampal neurons oxygen-glucose deprivation/reoxygenation（OGD/R）-induced ischemia-hypoxia model was constructed to evaluate the effects of different processed products of SMRR on oxidative damage of neuronal cells by taking lactate dehydrogenase（LDH）， reactive oxygen species（ROS）， MDA and SOD as indexes. Finally， principal component analysis（PCA）， partial least squares-discriminant analysis（PLS-DA） and Spearman correlation analysis were used to analyze the 11 small molecule active components and 1 protein component with efficacy indicators， in order to screen the key components of the characteristic processed products with porcine cardiac blood for cerebral ischemic oxidative damage. ResultCompared with the raw products， the contents of water-soluble and fat-soluble components in processed products of SMRR increased to different degrees， while the content of salvianolic acid A decreased. Compared with the wine-processed products， the contents of salvianolic acid B， danshensu， rosmarinic acid and other components in the porcine cardiac blood-processed products， porcine blood-processed products， Tf-processed products were increased， while the content of salvianolic acid A was decreased. ELISA results showed that there was no significant difference in Tf content between the porcine cardiac blood-processed products， porcine blood-processed products， Tf-processed products. Pharmacological results showed that different processed products of SMRR could improve the behavioral deficits， brain neuronal injury and oxidative stress after ischemic stroke in zebrafish， and the effect of the porcine cardiac blood-processed products was most pronounced. PCA results showed that salvianolic acid B， salvianolic acid A， rosmarinic acid， lithospermic acid， danshensu， tanshinone Ⅱ_A， caffeic acid， cryptotanshinone and tanshinone Ⅰ were the main contributing components of SMRR and its processed products. And the results of correlation analysis showed that the contents of cryptotanshinone， rosmarinic acid， caffeic acid， dihydrotanshinone Ⅰ， salvianolic acid B， tanshinone Ⅱ_A and tanshinone Ⅰ were negatively correlated with MDA level in zebrafish brain tissue， while the contents of lithospermic acid， protocatechuic aldehyde， rosmarinic acid， dihydrotanshinone Ⅰ， salvianolic acid B and Tf were positively correlated with SOD level， and the contents of rosmarinic acid， caffeic acid， dihydrotanshinone Ⅰ， salvianolic acid B， tanshinone Ⅱ_A， tanshinone Ⅰ， danshensu， Tf were positively correlated with neuronal fluorescence intensity in the zebrafish brain. And the contents of lithospermic acid， protocatechuic aldehyde， rosmarinic acid， dihydrotanshinone Ⅰ， salvianolic acid B， tanshinone Ⅱ_A and Tf were negatively correlated with LDH， ROS and MDA levels and positively correlated with SOD level. ConclusionThere are differences in the anti-ischemic oxidative damage effects of SMRR and its different processed products， among which the porcine cardiac blood-processed products has the strongest effect on improving oxidative damage， which may be related to the content changes of salvianolic acid B， danshensu， rosmarinic acid and other components. This study can provide a basis for clarifying the quality markers of SMRR processed with porcine cardiac blood for cerebral ischemia and elucidating its processing mechanism.

Objective:To investigate the regulatory effect of transient receptor potential cation channel subfamily C member 3 (TRPC3) on the retina in oxygen-induced retinopathy (OIR) mice and biological behavior of human retinal vascular endothelial cells (HREC).Methods:A total of 32 healthy SPF grade 7-day-old C57BL/6 mice were selected and randomly divided into a control group and an OIR group by the random number table method, with 16 mice in each group.The control group received no special treatment, and the OIR model was established in the OIR group.On postnatal day 17 (PN17), the success of the model establishment was verified by immunofluorescence staining of the retinal patch.The in vitro cultured HREC were divided into a normal control group, a transfection reagent group, and a si-TRPC3 group.The normal control group received no special treatment, while the transfection reagent group and the si-TRPC3 group were transfected with transfection reagent or transfection reagent + si-TRPC3.The relative expression of TRPC3 mRNA was detected by real-time quantitative fluorescence PCR.The relative expressions of TRPC3, transcription factor NF-E2 related factor (Nrf2), and superoxide dismutase (SOD) proteins were determined by Western blot.HREC were further divided into a normal control group, a vascular endothelial growth factor (VEGF) group, a si-TRPC3 group, and a Pyr3 (TRPC3 channel inhibitor) group, which were cultured in complete medium, medium containing 20 ng/ml VEGF recombinant protein, medium containing 20 ng/ml VEGF recombinant protein (si-TRPC3 transfection for 72 hours), and medium containing 20 ng/ml VEGF recombinant protein+ 1 μmol/L Pyr3 for 48 hours, respectively.The proliferation ability of HREC was detected using cell counting kit 8 (CCK-8). The horizontal and vertical migration ability of cells were detected by cell scratch assay and transwell assay, respectively.This study followed the 3R principles of animal welfare and was approved by the Ethics Committee of Hebei Eye Hospital (No.2023LW04). Results:Pathological neovascular clusters with strong fluorescent staining appeared in the retina of OIR mice on PN17.The relative expressions of TRPC3 mRNA and protein in the retina of OIR mice were 2.057±0.244 and 1.517±0.290, respectively, significantly higher than 0.983±0.033 and 0.874±0.052 of control group ( t=6.165, 3.094; both at P<0.05). The relative expression levels of TRPC3 mRNA and protein were significantly lower, and the relative expression levels of Nrf2 and SOD proteins were higher in the si-TRPC3 group than in the normal control and transfection reagent groups, and the differences were statistically significant (all at P<0.05). The CCK-8 experiment results showed that the cell absorbance value was higher in the VEGF group than in the normal control group, and lower in the si-TRPC3 and Pyr3 groups than in the VEGF group, with statistically significant differences (all at P<0.05). The results of the cell scratch experiment showed that the lateral migration rate of VEGF group cells was higher than that of normal control group, while the lateral migration rate of si-TRPC3 group and Pyr3 group cells was lower than that of VEGF group, and the differences were statistically significant (all at P<0.05). The transwell experiment results showed that the number of stained cells in the VEGF group was higher than that in the normal control group, and the number of stained cells in the si-TRPC3 group and Pyr3 group was lower than that in the VEGF group, with statistically significant differences (all at P<0.05). Conclusions:Hypoxia induces increased TRPC3 expression in OIR mouse retina, and downregulation of TRPC3 inhibits HREC proliferation and migration.The mechanism is related to the activation of the Nrf2-related oxidative stress pathway.
