Objective:To explore the clinical effect of Triangle hierarchical management in patients with acute non-ST-segment elevation myocardial infarction(NSTEMI)after percutaneous coronary intervention(PCI).Methods:A total of 107 NSTEMI patients who underwent PCI in our hospital from Jan 2019 to Dec 2022 were selected.Ac-cording to the random number table method,patients were divided into control group(n=53)and observation group(n=54).Patients in the control group received routine rehabilitation training,while observation group re-ceived Triangle hierarchical management based on control group,both groups were intervened for 6 months.Car-diopulmonary function indexes,scores of myocardial infarction dimensional assessment scale(MIDAS)and general self-efficacy scale(GSES)before and after intervention,and incidence of adverse events during follow-up were compared between two groups.Results:During study period,two cases were lost in the control group and one case withdrew in the observation group,with 51 and 53 cases finally enrolled in each group,respectively.Compared with the control group after intervention,there were significant rise in forced expiratory volume in one second(FEV1)[(2.98±0.27)L vs.(3.30±0.35)L],FEV1/forced vital capacity(FVC)[(72.65±4.31)％vs.(77.06±3.95)％]and GSES score[(18.53±2.63)points vs.(26.89±3.19)points],and significant reduction in MIDAS total score[(65.53±4.86)points vs.(56.26±4.38)points]in observation group(P＜0.001 all).There was no significant difference in the incidence rate of adverse events between control group and observation group during fol-low-up(13.73％vs.7.55％,P=0.306).Conclusion:Triangle hierarchical management may significantly improve lung function,self-efficacy and quality of life with high safety in patients with acute non-ST-segment elevation myocardial infarction after PCI,suggesting that it worths promoting in clinical practice.

OBJECTIVETo evaluate the effect of postoperative adjuvant transcatheter arterial chemoembolization (TACE) on hepatocellular carcinoma (HCC) patients with residual tumor.

METHODSThe patients were classified into intervention group (with adjuvant TACE) and control group (without adjuvant TACE) who were further stratified to those with high risk (patients with single tumor > 5 cm in diameter, or with multiple tumors, invasion to blood vessels), and low risk factors. Univariate analysis and Cox model were used to analyse prognostic factors.

RESULTSIn low risk patients with residual tumor, the 1-, 2-, 3-, 4-year survival rate was 97.2%, 78.0%, 66.5% and 66.5% in the intervention group, and 91.2%, 81.4%, 70.3% and 54.4% in the control group, respectively. There was no statistical difference between the two groups in survival (log-rank P = 0.7667). Comparing with the control group, the 1-, 2-, 3-, 4-year survival rate was 89.5%, 73.4%, 59.2% and 53.8% in the intervention group, and 70.5%, 61.9%, 46.8% and 46.8% in the control group, respectively. Postoperative adjuvant TACE significantly prolonged the survival in high risk patients with residual tumor (P = 0.0029). Cox model revealed that the benefit of adjuvant TACE was significantly increased by the high risk factors in HCC patients with residual tumor.

CONCLUSIONThe beneficial effect of postoperative TACE was only observed in high risk patients with residual tumor but not in the low risk patients with residual tumor.

A 44-year-old woman was transferred to the ICU of the First Affiliated Hospital of Jinan University for 2 days of persistent epigastric pain and 7 hours of unconsciousness. Her admission diagnosis was severe acute necrotizing pancreatitis (hypertriglyceridemia type) with multiple organ dysfunctions. The results of CT revealed a small area of necrotizing pancreatitis, which was not consistent with the severe clinical manifestations. Considering lack of hair and history of postpartum hemorrhage, hormone examination was carried out. According to the results of the examination, she was further diagnosed as Sheehan's syndrome and pituitary crisis. After hormone replacement therapy, her condition improved rapidly.

OBJECTIVE: To investigate the role of nucleophosmin (NPM) in the proliferation of chronic myeloid leukemia cells (K562 cells) and its mechanism by RNAi technology. METHODS: shRNA was used to inhibit the expression of NPM. The expression of NPM gene was detected by real-time quantitative PCR. The effect of inhibiting NPM gene on cell proliferation was detected by MTS assay. Change of cell cycle was detected by flow cytometry. Western blot was used to detect the expression of cell cycle-related proteins. RESULTS: The shRNA lentiviral vector targeting at NPM gene was successfully constructed and used to transfect the K562 cells. The results showed that compared with the control groups, suppression of NPM gene expression in K562 cells could inhibit the cell proliferation and decrease the cell colony formation. Moreover, interference of NPM gene could prolong G/G phase and arrest cell cycle, which may be related to the down-regulation of NPM gene expression and activation of p21 protein expression, thereby inhibited the formation of CDK2/ Cyclin E complex. CONCLUSION Down-regulation of NPM gene expression in K562 cells can induce cell cycle arrest and inhibit cell proliferation.

OBJECTIVE: To investigate the effect of baicalin derivative 02-036 on proliferation and apoptosis human Burkitt lymphoma cell line CA46 and its related mechanisms. METHODS: The MTT assay and cell colony formation assay were used to measure the growth inhibition of CA46 cells after 02-036 treatment. The flow cytometry with AnnexinV-FITC/PI double staining was employed to detect the apoptosis induction effect of 02-036 on CA46 cells. Cell cycle distribution of CA46 cells was estimeted by using DNA ploid analysis. Western blot was used to determine the changes of apoptosis-related proteins, including C-MYC, BCL-2, Procaspase-9, Procaspase-3, PARP and Cleaved-PARP. RESULTS: Baicalin derivative 02-036 obviously inhibited the proliferation of CA46 cells, with dose- and time-dependent manner (r=0.963, r=0.992). The averaged IC value of CA46 cells was (6.04±0.11) μmol/L after 48-hour treatment. Low concentration of 02-036 could significantly inhibit the colony formation of CA46 cells. Flow cytometry analysis confirmed that 02-036 could effectively induce CA46 cell apoptosis. The apoptosis rate correlated with drug concentrations (r=0.959). Also, DNA ploid analysis showed that the cell cycle of CA46 was arrested in the S phase. The expression levels of BCL-2, Pro-caspase-9, Pro-caspase-3, PARP and C-MYC proteins decreased with a 02-036-dose dependent manner (r values were -0.990, -0.939, -0.971 and -0.967, respectively). In contrast, the expression level of cleaved-PARP increased with the same manner (r=0.920). CONCLUSION Baicalin derivative 02-036 can effectively inhibit the proliferation and induce apoptosis of CA46 cells, and its related mechanisms may be correlated with the down-regulation of apoptosis-related molecule expression levels, such as BCL-2, Pro-caspase-9, Pro-caspase-3, PARP and C-MYC.

Objective To compare characteristics of stress variations in 3D finite element models of normal and degenerative lumbar vertebrae and the dose-effect relationship, and analyze the mechanism of mechanical balance by traditional Chinese medicine (TCM) manipulation on degenerative lumbar vertebrae. Methods The 3D finite element model of intact, real human degenerative lumbar vertebrae (L4-5) was established to simulate the physiological activity of flexion and extension in lumbar vertebrae. The characteristics of stress variation in degenerative lumbar vertebrae under external loading, namely, the TCM manipulation was analyzed, and the stress variation in degenerative lumbar vertebrae under gradual increasing-external loading was analyzed as well, which was compared with the stress and strain variation in normal lumbar vertebrae under different motion status. Results Under different motion status, the stress distributions on lumbar disc as well as the elastic modulus of nucleus pulposus and fiber ring showed a gradually increasing tendency with lumbar degeneration increasing. TCM manipulation could change the stress distributions on lumbar disc, enlarge the space of spinal canal to a certain degree, and decrease the stress on nerve root. Stresses on small joints of the vertebral body and vertebral pedicle under posterior extension were larger than those under anterior flexion, while stresses on intervertebral disc under anterior flexion were greater than those under posterior extension, which showed a gradually increasing trend from top to bottom. Conclusions The mechanical environment of human lumbar vertebrae can be balanced by TCM manipulation, for the purpose of improving and treating lumbar disc diseases. The comparison with the 3D finite element model of normal human lumbar vertebrae and investigation on lumbar degeneration from perspective of changes in biomechanical environment and characteristics can provide scientific basis for clinic application of TCM manipulation in prevention and treatment of lumbar degenerative diseases, as well as new research idea for studying mechanical mechanism of TCM manipulation in effective prevention and treatment of lumbar lesions.

The current study was designed to explore the brain protection mechanism of Xinglou Chengqi Decoction (XCD) based on gut microbiota analysis and network pharmacology. A transient middle cerebral artery occlusion (MCAO) model of mice was established, followed by behavioral evaluation, TTC and TUNEL staining. Additionally, to investigate the effects of gut microbiota on neurological function after stroke, C57BL/6 mice were treated with anti-biotic cocktails 14 days prior to ischemic stroke (IS) to deplete the gut microbiota. High-throughput 16S rDNA gene sequencing, metabonomics technique, and flow multifactor technology were used to analyze bacterial communities, SCFAs and inflammatory cytokines respectively. Finally, as a supplement, network pharmacology and molecular docking were applied to fully explore the multicomponent-multitarget-multichannel mechanism of XCD in treating IS, implicated in ADME screening, target identification, network analysis, functional annotation, and pathway enrichment analysis. We found that XCD effectively improved neurological function, relieved cerebral infarction and decreased the neuronal apoptosis. Moreover, XCD promoted the release of anti-inflammatory factor like IL-10, while down-regulating pro-inflammatory factors such as TNF-α, IL-17A, and IL-22. Furthermore, XCD significantly increased the levels of short chain fatty acids (SCFAs), especially butyric acid. The mechanism might be related to the regulation of SCFAs-producing bacteria like Verrucomicrobia and Akkermansia, and bacteria that regulate inflammation like Paraprevotella, Roseburia, Streptophyta and Enterococcu. Finally, in the network pharmacological analysis, 51 active compounds in XCD and 44 intersection targets of IS and XCD were selected. As a validation, components in XCD docked well with key targets. It was obviously that biological processes were mainly involved in the regulation of apoptotic process, inflammatory response, response to fatty acid, and regulation of establishment of endothelial barrier in GO enrichment. XCD can improve neurological function in experimental stroke mice, partly due to the regulation of gut microbiota. Besises, XCD has the characteristic of "multi-component, multi-target and multi-channel" in the treatment of IS revealed by network pharmacology and molecular docking.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
