PURPOSE:
To investigate the protective effect of sub-hypothermic mechanical perfusion combined with membrane lung oxygenation on ischemic hypoxic injury of yorkshire brain tissue caused by traumatic blood loss.
METHODS:
This article performed a random controlled trial. Brain tissue of 7 yorkshire was selected and divided into the sub-low temperature anterograde machine perfusion group (n = 4) and the blank control group (n = 3) using the random number table method. A yorkshire model of brain tissue injury induced by traumatic blood loss was established. Firstly, the perfusion temperature and blood oxygen saturation were monitored in real-time during the perfusion process. The number of red blood cells, hemoglobin content, NA+, K+, and Ca2+ ions concentrations and pH of the perfusate were detected. Following perfusion, we specifically examined the parietal lobe to assess its water content. The prefrontal cortex and hippocampus were then dissected for histological evaluation, allowing us to investigate potential regional differences in tissue injury. The blank control group was sampled directly before perfusion. All statistical analyses and graphs were performed using GraphPad Prism 8.0 Student t-test. All tests were two-sided, and p value of less than 0.05 was considered to indicate statistical significance.
RESULTS:
The contents of red blood cells and hemoglobin during perfusion were maintained at normal levels but more red blood cells were destroyed 3 h after the perfusion. The blood oxygen saturation of the perfusion group was maintained at 95% - 98%. NA+ and K+ concentrations were normal most of the time during perfusion but increased significantly at about 4 h. The Ca2+ concentration remained within the normal range at each period. Glucose levels were slightly higher than the baseline level. The pH of the perfusion solution was slightly lower at the beginning of perfusion, and then gradually increased to the normal level. The water content of brain tissue in the sub-low and docile perfusion group was 78.95% ± 0.39%, which was significantly higher than that in the control group (75.27% ± 0.55%, t = 10.49, p < 0.001), and the difference was statistically significant. Compared with the blank control group, the structure and morphology of pyramidal neurons in the prefrontal cortex and CA1 region of the hippocampal gyrus were similar, and their integrity was better. The structural integrity of granulosa neurons was destroyed and cell edema increased in the perfusion group compared with the blank control group. Immunofluorescence staining for glail fibrillary acidic protein and Iba1, markers of glial cells, revealed well-preserved cell structures in the perfusion group. While there were indications of abnormal cellular activity, the analysis showed no significant difference in axon thickness or integrity compared to the 1-h blank control group.
CONCLUSIONS
Mild hypothermic machine perfusion can improve ischemia and hypoxia injury of yorkshire brain tissue caused by traumatic blood loss and delay the necrosis and apoptosis of yorkshire brain tissue by continuous oxygen supply, maintaining ion homeostasis and reducing tissue metabolism level.

OBJECTIVE:
To explore a predictive model that can better predict the prognosis of patients with diffuse large B-cell lymphoma (DLBCL), and validate its clinical value.
METHODS:
Clinical data of 134 newly treated DLBCL patients were collected from Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2015 to January 2020. Several risk factors of the patients were screened and analyzed, a novel prognostic model were then established based on this, and its clinical application potential was validated.
RESULTS:
In the novel model, predicting progression-free survival (PFS) based on the age at initial treatment, albumin level, Hans classification, Ann Arbor stage, and BCL2 expression showed better predictive performance than International Prognostic Index (IPI) score (AUC: 0.788 vs 0.620,P <0.001). Predicting overall survival (OS) based on the age at initial treatment, albumin level, lactate dehydrogenase (LDH) level, and expressions of BCL2 and MUM1 proteins also showed better predictive performance for mortality risk than IPI score (AUC: 0.817 vs 0.624,P <0.001).
CONCLUSION
This novel prognostic model can better predict the survival prognosis of DLBCL patients compared to the IPI scoring system.

OBJECTIVE:
To precise classify sacral meningeal cysts, effective guide minimally invasive neurosurgery and postoperative personalized rehabilitation by multiple dimensions radiographic reconstruction MRI.
METHODS:
From March to December 2021, based on the original 3D-fast imaging employing steadystate acquisition (FIESTA) scanning sequence, 92 patients with sacral meningeal cysts were pre-operatively evaluated by multiple dimensional reconstruction MRI. The shape of nerve root and the leakage of cyst were reconstructed according to the direction of nerve root or leakage track showed on original MRI scans. Sacral canal cysts were accurately classified as including nerve root and without nerve root, so as to accurately design the incision of skin and formulate corresponding open range of the posterior wall of the sacral canal. Under the microscope intraoperation, the shape of the nerve roots inside cysts or leakage track of the cysts without nerve roots were verified and explored. After the reinforcement and shaping operation, several reexaminations of multiple dimensional reconstruction MRI were performed to understand the deformation of the nerve root and hydrops in the operation cavity, so as to formulate a persona-lized rehabilitation plan for the patients.
RESULTS:
Among the 92 patients with sacral mengingeal cyst, 58 (63.0%) cysts with nerve root cyst, 29 (31.5%) cysts without nerve root cyst, and 5 (5.4%) cysts with mixed sacral canal cyst. In 58 patients with nerve root cysts, the accuracy of preoperative clinical classification on MRI image reached 96.6% (56/58) through confirmation by operating microscope. Only 2 cases of large single cyst with nerve root on the head of cyst were mistaken for without nerve root type. In 29 patients with sacral cyst without nerve root, the accuracy of preoperative image reached 100% through confirmation by operating microscope. The accuracy of judging the internal nerve root and leakage of 12 cases with recurrent sacral cyst was also 100%. Two cases of delayed postoperative hydrops were found one month after operation. After rehabilitation treatment by moxibustion and bathing, the hydrops disappeared 4-6 months after operation.
CONCLUSION
Multiple dimensional reconstruction MRI can precisely make clinical classification of sacral meningeal cysts before operation, guide minimally invasive neurosurgery effectively, and improve the rehabilitation effect.

OBJECTIVE:
To explore the effect of acupuncture therapy on dysphagia in patients with Parkinson's disease.
METHODS:
This randomized controlled study lasted 42 days and included 112 patients with Parkinson's disease and dysphagia. Participants were randomly assigned to the experimental and control groups (56 cases each group) using the completely randomized design, all under routine treatment. The experimental group was given acupuncture therapy. The primary outcome was Penetration-Aspiration Scale (PAS). The secondary outcomes were (1) Standardized Swallowing Assessment (SSA), and (2) nutritional status including body mass index (BMI), serum albumin, prealbumin, and hemoglobin. Adverse events were recorded as safety indicators.
RESULTS:
One participant quitted the study midway. There were no significant differences in baseline assessment (P>0.05). After treatment, both groups showed significant improvement in PAS, SSA and nutritional status except for BMI of the control group. There were significant differences between the two groups in the PAS for both paste and liquid, SSA (25.18±8.25 vs. 20.84±6.92), BMI (19.97±3.34 kg/m2vs. 21.26 ±2.38 kg/m2), serum albumin (35.16 ±5.29 g/L vs. 37.24 ±3.98 g/L), prealbumin (248.33 ±27.72 mg/L vs. 261.39 ±22.10 mg/L), hemoglobin (119.09±12.53 g/L vs. 126.67±13.97 g/L) (P<0.05). There were no severe adverse events during the study.
CONCLUSION:
The combination of routine treatment and acupuncture therapy can better improve dysphagia and nutritional status in patients with Parkinson's disease, than routine treatment solely. (registration No.

Objective:To investigate the effect of miR-1-3p on mitophagy in human esophageal squamous cell carcinoma (ESCC) cells and the related mechanisms.Methods:The differentially expressed miRNAs in ESCC were screened using the GEO database. Real-time quantitative polymerase chain reaction (RT-qPCR) was used to measure miR-1-3p expression in normal esophageal epithelial cells (HET-1A) and ESCC cell lines (TE1, KYSE30, KYSE150, KYSE410, Eca109). Bioinformatics tools were utilized to predict target genes of miR-1-3p, subcellular localization was confirmed by fluorescence in situ hybridization. The targeting relationship between miR-1-3p and SLC7A11 was validated using dual-luciferase reporter assay. Cell proliferation and apoptosis were detected by CCK8 assay and flow cytometry, respectively. Furthermore, experimental validation demonstrated that overexpression of SLC7A11 rescued the presence of the miR-1-3p/SLC7A11 axis. Confocal microscopy was used to detect changes in mitochondrial autophagic lysosomes, while transmission electron microscopy was employed to observe mitophagy and morphological alterations. Western blot was conducted to evaluate the expression of autophagy-related proteins LC3 and P62. Flow cytometry was used to measure mitochondrial membrane potential and reactive oxygen species (ROS). Immunohistochemistry was applied to assess SLC7A11 expression in 133 ESCC patient tissues and 115 normal esophageal epithelial tissues. The correlation between SLC7A11 expression level and clinicopathological features was analyzed. Survival analysis was performed using the Kaplan-Meier method, and Cox proportional hazard regression models were used for multivariate analysis.Results:The expression of miR-1-3p in ESCC cells was significantly lower than that in HET-1A cells ( P<0.05). SLC7A11 was a target gene of miR-1-3p. Transfection of miR-1-3p mimic inhibited the proliferation of ESCC cells. CCK-8 assay results showed that the proliferative capacity of KYSE30 and KYSE410 cells in the miR-1-3p mimic group (absorbance values: 2.88±0.24 and 2.88±0.18, respectively) was significantly lower than that in the miRNA mimic negative control (NC) group (3.94±0.27, P<0.001; 4.20±0.21, P<0.001). Meanwhile, the proliferative capacity of KYSE30 and KYSE410 cells in the miR-1-3p mimic+SLC7A11-overexpression (OE) group (absorbance values: 3.57±0.15 and 3.60±0.13, respectively) was significantly higher than that in the miR-1-3p mimic +empty vector (EV) group (2.54±0.10, P<0.001, 2.36±0.16, P<0.001). Additionally, transfection of miR-1-3p mimic promoted apoptosis. Flow cytometry results demonstrated that the apoptosis rates of KYSE30 and KYSE410 cells in the miR-1-3p mimic group [(9.22±0.05)% and (6.55±0.37)%, respectively] were significantly higher than those in the miRNA mimic NC group [(0.81±0.17)%, P<0.001); (1.04±0.12)%, P<0.001]. Conversely, the apoptosis rates of KYSE30 and KYSE410 cells in the miR-1-3p mimic + SLC7A11-OE group [(0.73±0.04)% and (1.19±0.05)%, respectively] were significantly lower than those in the miR-1-3p mimic+EV group [(9.83±0.41)%, P<0.001); (6.09±0.17)%, P<0.00)]. MiR-1-3p mimic downregulated SLC7A11 protein expression and the LC3Ⅱ/LC3I ratio ( P<0.05), upregulated P62 protein expression ( P<0.05), this phenomenon can be rescued by overexpressing SLC7A11 ( P<0.05). Additionally, miR-1-3p mimic increased ROS levels and decreased mitochondrial membrane potential (JC-1 aggregate/monomer ratio), this phenomenon can be rescued by overexpressing SLC7A11 ( P<0.05). SLC7A11 expression was higher in ESCC tissues compared to normal esophageal epithelial tissues ( P<0.001), and SLC7A11 serves as an independent prognostic factor in ESCC ( HR=2.15, 95% CI: 1.27-3.65, P=0.004). Conclusion:miR-1-3p inhibits mitophagy in esophageal squamous cell carcinoma by targeting SLC7A11.
