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 ⅡA, 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 ⅡA 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 ⅡA, 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 ⅡA 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 summarize the distributional characteristics of postoperative occurrence of multi-drug resistant organism (MDRO) infections and their risk factors in simultaneous pancreas-kidney transplantation (SPK) recipients and examine the impact of MDRO infections on the survival of SPK recipients.Method:From January 2016 to December 2022, the relevant clinical data were retrospectively reviewed for 218 SPK recipients. The source of donor-recipient specimens and the composition percentage of MDRO pathogens were examined. According to whether or not MDRO infection occurred post-transplantation, they were assigned into two groups of MDRO (98 cases) and non-MDRO (120 cases). The clinical data of two groups of donors and recipients were analyzed. And the risk factors for an onset of MDRO infection were examined by binary Logistic regression. The survival rate of two recipient groups was compared by Kaplan-Meier method.Result:A total of 98/218 recipients (45%) developed MDRO infections. And 46 (46.9%) of sputum and 34 (34.7%) of urine were cultured positively and 49 (50%) pathogens expressed extended spectrum beta-lactamase. There were pneumonia (46 cases, 46.9%), urinary tract infections (34 cases, 34.7%), abdominal infections (16 cases, 16.3%) and bloodstream infections (2 cases, 2.0%). Univariate regression analysis revealed that length of renal failure ( P=0.037), length of hospitalization ( P<0.001), length of antibiotic use ( P<0.001), novel antibiotics ( P=0.014), albumin ( P<0.001) and leukocyte count ( P<0.001) were risk factors for an onset of MDRO infections. The results of multifactorial regression indicated that low albumin ( OR=0.855, 95% CI: 0.790~0.925, P<0.001) and leukopenia ( OR=0.656, 95% CI: 0.550~0.783, P<0.001) were independent risk factors for an onset of MDRO infections. The survival rates of recipients in MDRO group at Year 1/3 post-operation were 92.9% (91/98) and 89.8% (88/98). And the survival rate of recipients in non-MDRO group was 96.7% (116/120) at Year 1/3 post-operation. Inter-group difference was not statistically significant in 1-year survival rate of two recipient groups ( P=0.201); statistically significant inter-group difference in 3-year survival rate between two recipient groups ( P=0.041) . Conclusion:Low albumin and leukopenia are risk factors for MDRO infection. Infection with MDRO has some impact on the survival of recipients.

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.

Objective:To construct a quality evaluation index system for postoperative rehabilitation in children with developmental dislocation of the hip (DDH) .Methods:From August to November 2021, a quality evaluation index system for postoperative rehabilitation in children with DDH was established through literature review, group discussion, and Delphi expert consultation. The analytic hierarchy process was used to determine the weights of various indicators. The positive coefficient of experts was expressed by the effective response rate of the questionnaire. The authority level of experts was represented by the authority coefficient ( Cr) , which was determined by the expert judgment coefficient ( Ca) and the expert familiarity level ( Cs) . The degree of coordination of expert opinions was represented by the Kendall harmony coefficient (Kendall's W) . The degree of concentration of expert opinions was represented by the average score of importance assignment, coefficient of variation, and full score rate. Results:The effective response rates of the two rounds of expert consultation questionnaires were 90.00% and 100.00%, respectively. The Cr of experts in two rounds were 0.785 and 0.815, and the Kendall harmony coefficients were 0.098-0.193 and 0.147-0.212 ( P<0.05) . In the second round of expert consultation, the average scores of importance assignment for all levels of indicators were≥4.0, with coefficients of variation of 0-0.24 and a full score rate of ≥50%. The final quality evaluation index system for postoperative rehabilitation in children with DDH included 3 first-level indicators, 9 second-level indicators, and 37 third-level indicators. In the consistency test results of each indicator at all levels, all of the CI were <0.001, and all of the CR were<0.001. Conclusions:The construction process of the quality evaluation index system for postoperative rehabilitation in children with DDH is scientific, and the weight distribution of the indicators is reasonable, which can be used as an effective tool for evaluating the postoperative rehabilitation quality of DDH children.
