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 effect of polymorphisms of solute carrier organic anion transporter family, member 1B3(SLCO1B3) gene on the pharmacodynamics of mycophenolate mofetil(MMF) in patients with lupus nephritis. METHODS Patients with lupus nephritis who were treated in Jieyang People’s Hospital from September 2019 to April 2021 were selected. All subjects were treated with MMF for at least 12 months, or discontinued due to poor efficacy. The efficacy of MMF was evaluated. The SLCO1B3 334T>G/699G>A(rs4149117/rs7311358) genotype was detected using Agena MassARRAY®, and the correlation between gene polymorphisms and MMF pharmacodynamics was analyzed using SPSS 25.0 software. RESULTS The genotype frequencies of SLCO1B3 334T>G/699G>A were in Hardy-Weinberg equilibrium. The probability of poor MMF treatment effect of 334GG/699AA carriers was significantly higher than that of 334TT/699AA and 334TG/699GA carriers(P<0.001); Logistic regression showed that both 334GG/699AA and urine protein>2.5 g·(24 h)−1 were the risk factors for poor MMF treatment[OR=4.038(1.731, 9.420), P<0.001; OR=4.157(1.705, 10.137), P=0.002]. Combined analysis showed that patients with both 334GG/699AA genotype and urine protein>2.5 g·(24 h)−1 were at higher risk for poor efficacy[OR=8.563(3.301, 22.216), P<0.001]. CONCLUSION SLCO1B3 334T>G/699G>A is related to the efficacy of MMF treating lupus nephritis, and 334GG/699AA carriers are more likely to result in poor efficacy.

Objective To evaluate the efficacy,safety and economy of cyclin-dependent kinase 4/6(CDK4/6)inhibitors for the first-line treatment of hormone receptors positive(HR+),human epidermal growth factor receptor 2 negative(HER2-)advanced breast cancer(ABC)by rapid health technology assessment,and to provide evidence for clinicians and policymakers.Methods PubMed,Cochrane Library,Embase,CNKI,WanFang Data,VIP databases and the official website of health technology assessment(HTA)agency were electronically searched to collect clinical evidence and literature of CDK4/6 inhibitors in the treatment of HR+/HER2-ABC from the inception to December 31,2023.Two reviewers independently identified studies,extracted data,assessed the quality of included studies,and descriptively analyzed and summarised the results.Results A total of 33 articles were included,including 9 systematic reviews/Meta-analyses,15 pharmacoeconomic studies and 9 HTA reports.In terms of efficacy,compared with endocrine therapy alone,the addition of CDK4/6 inhibitors significantly improved progression-free survival(PFS)and overall survival(OS)in patients with HR+/HER2-ABC(P＜0.05),but there was no significant difference in efficacy among palbociclib,abemaciclib and ribociclib(P＞0.05).In terms of safety,more adverse events were observed in patients treated with CDK4/6 inhibitors when compared with endocrine therapy(P＜0.05).There was a difference in the incidence of adverse effects between the different CDK4/6 inhibitors,with palbociclib having higher incidence of haematological adverse effects(P＜0.05),and abemaciclib being more likely to cause gastrointestinal adverse reactions such as diarrhoea(P＜0.05).The economic evaluation results were variable due to differences in healthcare costs,analysis perspectives,willingness-to-pay thresholds,and study duration in different countries.Conclusion CDK4/6 inhibitors have similar efficacy in the first-line treatment of HR+/HER2-ABC patients,but there are some differences in aspects such as safety and economy.

ObjectiveProteomics was used to investigate the protein differences between porcine cardiac blood（PCB） and porcine blood（PB） from Menghe medical school and to compare the effects of both on the microglial inflammation of Salviae Miltiorrhizae Radix et Rhizoma（DS）. MethodNanoliquid chromatography-quadrupole orbitrap mass spectrometry（nLC-MS/MS） and bioinformatics were utilized to compare the proteomic differences of PCB and PB in simulated gastrointestinal digestion. Furthermore， Western blot was used to verify the contents of some shared proteins and differential proteins identified in PCB and PB. In addition， BV2 neuroinflammation model constructed by corticosterone（CORT） and lipopolysaccharide（LPS） was applied to detect the intervention effects of PCB and PB on the levels of tumor necrosis factor（TNF）-α and interleukin（IL）-6 in BV2 inflammatory cells of DS. ResultA total of 69 common proteins and 68 differential proteins were identified in PCB and PB， among which the common proteins included transferrin（Tf） with brain-targeting effect， and the differential proteins in the two were 41 and 27， respectively. Western blot validation showed that the difference in the content of the same protein Tf between PCB and PB was not statistically significant， while the difference in the contents of the specific proteins of creatine kinase M and heart-type fatty acid binding protein（H-FABP） were statistically significant（P<0.05）. Moreover， in vitro experimental studies revealed that compared with the same concentration of DS group， in addition to the 100 mg·L^-1 PB-DS group， PCB-DS and PB-DS groups could significantly inhibit the levels of TNF-α and IL-6 in BV2 inflammatory cells（P<0.05， P<0.01）， and PCB-DS group had more significant anti-inflammatory effect than PB-DS group with the same concentration（P<0.05， P<0.01）. ConclusionBoth of PCB and PB can enhance the inhibitory effect of DS on the release of inflammatory factors， thus playing a neuroprotective role， and PCB promotes DS inhibition more significantly， which may be due to the existence of the two involved in energy metabolism-related differential proteins， which can lay a foundation for revealing the scientific connotation of the processing of PCB-DS and PB-DS.

Ischemic stroke in young adults has attracted more and more attention due to the diversity of its etiology. Although atherosclerosis is the most common cause of stroke in young adults, other or unknown causes are not uncommon . To improve clinicians′ understanding of the etiological diagnosis of stroke in young adults, this article reports a case of ischemic stroke in the First Affiliated Hospital of Jinan University. The patient was a 22-year-old male with acute onset who was diagnosed with acute ischemic stroke based on clinical presentation, physical examination, and magnetic resonance imaging of the brain. After actively searching for the cause, laboratory and genetic tests revealed that the patient had inherited thrombophilia (protein C and protein S deficiency), and cardiac magnetic resonance imaging examination found that the patient had noncompaction of the ventricular myocardium.

Objective:To investigate the effects of hydroxysafflor yellow A (HSYA) on depressive-like behavior and expression of type A γ-aminobutyric acid receptor(GABAAR)in hippocampus of chronic restraint stress model mice.Methods:The SPF grade male C57BL/6C mice were divided into Control group, HSYA group, Model group, Model + HSYA group and Model + fluoxetine group according to random number table method, with 12 mice in each group.Mice model of depression was established by chronic restraint stress.Mice in HSYA group and Model+ HSYA group were intraperitoneally injected with HSYA(20 mg/kg), mice in Model+ fluoxetine group were injected intraperitoneally with fluoxetine (10 mg/kg), and mice in Control group and Model group administered with 0.9% sodium chloride solution intraperitoneally once a day for 14 days.Then, the forced swimming test (FST) and tail suspension test (TST) were performed to evaluate the depressive-like behavior of mice, and the protein expression levels of different subtypes of GABAAR in the hippocampus of mice were determined by Western blot.SPSS 19.0 and GraphPad Prism 8.0 software were used for data statistical analysis and mapping.One-way ANOVA was used for comparison among groups, and Tukey-HSD test was used for further pairwise comparison.Results:(1) In the behavioral tests, there were significant differences in swimming immobility time of FST and tail suspension immobility time of TST among the five groups ( F=21.59, 20.81, both P<0.05). The swimming immobility time ((143.91±9.97) s) and tail suspension immobility time (( 107.00±6.54) s) in Model group were higher than those in Control group ((52.92±6.70) s, ( 43.50±5.96) s, both P<0.05). There were no significant difference in swimming immobility time and tail suspension immobility time between Model+ HSYA group ((26.17±7.69)s, ( 20.17±7.89)s) and Model+ fluoxetine group ((61.60±16.22)s, (34.14±10.74)s)(both P>0.05), but the swimming immobility time and tail suspension immobility time in these two groups were lower than those in Model group (both P<0.05). (2) The Western blot results showed that there were significant differences in the expression of GABAARβ1 and GABAARβ2 protein in hippocampus among the four groups ( F=12.21, 11.40, both P<0.05). The expression levels of GABAARβ1(45.60±10.76) and GABAARβ2 (46.27±4.82) protein in hippocampus of Model group were lower than those in Control group ((100.00±3.44), (100.00±3.26), both P<0.05). Compared to Model group, the expression of GABAARβ1 (79.91±5.00) and GABAARβ2 (79.08±5.53) protein in hippocampus of Model+ HSYA group were higher (both P<0.05). In addition, the expression of GABAARα1 and GABAARγ1 proteins in hippocampus were not significantly different among the four groups( F=0.23, 0.10, both P>0.05). Conclusion:HSYA can effectively alleviate depressive-like behavior in depression model mice, which may be related with the upregulation of GABAARβ1 and GABAARβ2 of hippocampus tissue.
