Parkinson’s disease (PD) is a common neurodegenerative disorder with profound impact on patients’ quality of life and long-term health, and early detection and intervention are particularly critical. In recent years, the search for precise and reliable biomarkers has become one of the key strategies to effectively address the clinical challenges of PD. In this paper, we systematically evaluated potential biomarkers, including proteins, metabolites, epigenetic markers, and exosomes, in the peripheral blood of PD patients. Protein markers are one of the main directions of biomarker research in PD. In particular, α‑synuclein and its phosphorylated form play a key role in the pathological process of PD. It has been shown that aggregation of α-synuclein may be associated with pathologic protein deposition in PD and may be a potential marker for early diagnosis of PD. In terms of metabolites, uric acid, as a metabolite, plays an important role in oxidative stress and neuroprotection in PD. It has been found that changes in uric acid levels may be associated with the onset and progression of PD, showing its potential as an early diagnostic marker. Epigenetic markers, such as DNA methylation modifications and miRNAs, have also attracted much attention in Parkinson’s disease research. Changes in these markers may affect the expression of PD-related genes and have an important impact on the onset and progression of the disease, providing new research perspectives for the early diagnosis of PD. In addition, exosomes, as a potential biomarker carrier for PD, are able to carry a variety of biomolecules involved in intercellular communication and pathological regulation. Studies have shown that exosomes may play an important role in the pathogenesis of PD, and their detection in blood may provide a new breakthrough for early diagnosis. It has been shown that exosomes may play an important role in the pathogenesis of PD, and their detection in blood may provide new breakthroughs in early diagnosis. In summary, through in-depth evaluation of biomarkers in the peripheral blood of PD patients, this paper demonstrates the important potential of these markers in the early diagnosis of PD and in the study of pathological mechanisms. Future studies will continue to explore the clinical application value of these biomarkers to promote the early detection of PD and individualized treatment strategies.

Objective To investigate the preventive effects of lidocaine administered through different routes on cardiovascular stress responses during anesthesia tracheal intubation. Methods Total 120 patients scheduled for elective surgery under general anesthesia were randomly divided into three groups: intravenous injection group (group IV), throat spray group (group LJ), and control group (group CT), with 40 patients in each. Group IV received 50 mg of lidocaine via intravenous injection 1 minute before tracheal intubation. Group LJ received 50 mg of lidocaine sprayed into the pharyngeal cavity, glottis, and subglottic area. Group CT did not receive any treatment, and the remaining procedures were performed following the routine general anesthesia induction protocol. Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) were recorded at four time points: T0 (before tracheal intubation), T1 (immediately after tracheal intubation), T2 (3 minutes after intubation), and T3 (5 minutes after intubation). Statistical analysis of the data was performed using SPSS 22.0. Results There were no significant differences in HR at various time points within the group LJ. The changes in HR in the group IV and group CT were different statistically from those in the throat spray group. The blood pressure of patients in all three groups increased to varying degrees immediately after tracheal intubation, with the group CT showing particularly significant changes that differed significantly from both the group IV and the group LJ. The group LJ rapidly returned to levels close to those before intubation. Conclusion The preventive effects of lidocaine on stress responses during tracheal intubation were different depending on the route of administration. The inhibitory preventive effect of the throat spray method was superior to that of intravenous lidocaine, especially in preventing changes in heart rate.

ObjectiveTo explore the effects of astragalin (AST) on autophagy and apoptosis of astrocytes in the L4-5 dorsal horn of the spinal cord in mice with inflammatory pain induced by complete Freund's adjuvant (CFA). MethodsTwenty-four male C57BL/6 mice, aged six months, were randomly assigned to four groups: control group, saline group, CFA model group, and CFA+AST group, six mice in each group. The inflammatory pain model was established by injection of 10 µL CFA into the right lateral malleolus fossa. The saline group were injected with an equal amount of normal saline at the same site. The inflammatory pain mice in CFA+AST group were further treated with AST (60 mg/kg) intraperitoneally once a day for 21 consecutive days. Multiplex immunofluorescence staining was used to detect the coexpression of autophagy-related factors including ATG 12 and Beclin-1, apoptosis-related factors including Cleaved-Caspase3 and Caspase9, and the astrocyte marker such as GFAP in the L4-5 spinal dorsal horn of the mice in each group. Western blot was used to examine the protein expression levels of autophagy-related proteins(ATG12, Beclin-1) and apoptosis-related proteins(Caspase 3, Caspase 9) in the L4-5 spinal dorsal horn of mice. ResultsImmunofluorescent staining showed that in the L4-5 dorsal horn of the spinal cord, the fluorescence intensity of ATG12 (P<0.000 1) and Beclin-1 (P<0.000 1) was significantly increased, while that of Cleaved-Caspase 3 (P<0.001) and Caspase 9 (P<0.000 1) was decreased in the CFA+AST group when compared to the CFA model group. Furthermore, AST could inhibit the activation of astrocytes. Western blot further confirmed that AST significantly upregulated the expression of ATG12 (P<0.000 1) and Beclin-1 (P<0.000 1) in the L4-5 spinal cord of CFA mice, and downregulated the expression of Caspase 3 (P<0.01) and Caspase 9 (P<0.001). ConclusionsAST promotes autophagy of astrocytes and inhibits their apoptosis in the L4-5 spinal dorsal horn of CFA mice.

ObjectiveTo explore the effect of different drying conditions on the appearance and intrinsic quality indicators of Pinelliae Rhizoma for screening suitable drying conditions, so as to provide reference for its standardized production and quality evaluation. MethodsDifferent dried samples of Pinelliae Rhizoma were prepared by lime-assisted sweating method and intermittent drying method. Visual analysis was employed to measure the color brightness values(L*) of the surface, cross-section and powder of the samples, texture analyzer was used to determine the hardness of the samples under different drying conditions. The total starch content was calculated by measuring the contents of amylose and amylopectin in the samples with ultraviolet-visible spectroscopy. High performance liquid chromatography(HPLC) was used to determine the contents of seven nucleoside components(uracil, hypoxanthine, uridine, inosine, guanosine, β-thymidine and adenosine) in the samples. Pearson correlation analysis was conducted to explore the correlation between the external characteristics and intrinsic indicators of the different dried samples. Principal component analysis(PCA) was used to comprehensively rank the data of various indicators, and partial least squares-discriminant analysis(PLS-DA) was used to screen differential components with variable importance in the projection(VIP) value>1. Furthermore, the difference between the optimal drying condition for Pinelliae Rhizoma and the traditional sun-drying method was explored by independent samples t-test. ResultsWith the increase of temperature, the color of the intermittently dried samples gradually deepened, while their hardness gradually decreased. Concurrently, the contents of extract, total starch, uridine and adenosine exhibited an upward trend, whereas the contents of uracil, hypoxanthine and inosine displayed a downward trajectory. Compared with the intermittent drying group, the content of extract in the samples subjected to lime-assisted sweating increased. With the increase of lime dose, the hardness and the total content of nucleoside components in the samples showed a downward trend, while the total starch content showed an upward trend. Correlation analysis showed that the comprehensive score of L* was negatively correlated with the contents of uracil, hypoxanthine and inosine, and positively correlated with the contents of uridine, guanosine and adenosine. Hardness was negatively correlated with adenosine content, and positively correlated with the contents of inosine, uracil and hypoxanthine. Through comprehensive consideration and comprehensive score of principal components, the method of 5% lime-mixed sweating for 6 days emerged as the top-ranking approach. Except for the extract, the results of independent samples t-test showed that there was no significant difference between the 5% lime-mixed sweating for 6 days and the traditional sun-drying in terms of other content indicators. ConclusionThe whiteness and firmness of Pinelliae Rhizoma exhibit significant correlations with its chemical composition, while uridine, uracil, guanosine, adenosine and inosine are the key constituents responsible for the quality difference of Pinelliae Rhizoma under different drying conditions. The lime-assisted sweating method optimized in this study can be proposed as a viable alternative to the traditional sun-drying method. This method not only ensures the quality of the medicinal material but also effectively reduces the drying time and prevents mold contamination, which provides a valuable reference for the standardization of drying conditions and the establishment of quality evaluation criteria for Pinelliae Rhizoma.

Objective: To retrospectively analyze the clinical data of 474 newborns with hyperbilirubinemia, and to investigate the clinical characteristics of hyperbilirubinemia caused by ABO hemolytic disease of the fetus and newborn (ABO-HDFN) and factors influencing the phototherapy duration. Methods: A total of 474 neonates with hyperbilirubinemia treated in the First Hospital of Lanzhou University from January 2019 to January 2023 were enrolled. Blood type identification and the standard serological tests (direct antiglobulin test, serum free antibody test, and antibody elution test) were performed for all neonates. Baseline clinical data were collected and analyzed. According to the results of the hemolysis tests, neonates were divided into hemolytic jaundice group and non-hemolytic jaundice group. Clinical indicators, including hemoglobin levels, length of hospital stay, and phototherapy duration, were compared between the two groups. A multiple linear regression model was used to explore clinical factors influencing the duration of phototherapy. Results: Among the 474 neonates with hyperbilirubinemia, 354 were diagnosed with ABO-HDFN (hemolytic group), while 120 were without ABO-HDFN (non-hemolytic group). The incidence of ABO-HDFN in neonates with blood type A (55.93%, 198/354) was significantly higher than those with blood type B (44.07%, 156/354) (P<0.05). Furthermore, neonates born to multiparous women had a significantly higher ABO-HDFN incidence (81.56%, 146/179) than first-born neonates (70.51%, 208/295) (P<0.05). Neonates in the hemolytic group had significantly lower hemoglobin levels (170.67±21.86 g/L vs 178.99±22.05 g/L, P<0.001), lower red blood cell counts (4.66±0.63×10
/L vs 4.89±0.59×10
/L, P<0.05), and lower hematocrit (50.05±6.56% vs 52.61±6.75%, P<0.05) compared to the non-hemolytic group. Additionally, the hemolytic group had significantly longer hospital stays (6 [5, 9] days vs 6 [4, 8] days), longer phototherapy duration (62 [38, 84.25] h vs 53 [34.25, 64.77] h), and higher frequency of jaundice episodes (9 [7, 13] times vs 8 [6, 12] times] compared to the non-hemolytic group (all P<0.05). Regression analysis indicated that a positive indirect Coombs test and multiparity were independent risk factors associated with prolonged phototherapy duration (P<0.05). Conclusion: ABO incompatibility is the leading cause of hemolytic disease in neonates, particularly in cases where the mother has blood type O and the neonate has blood type A. In such cases, close monitoring of bilirubin levels is strongly recommended. Multiparous pregnancies increase the risk of alloimmune hemolysis. Therefore, neonates born to multiparous women may require more frequent bilirubin monitoring and appropriate prenatal interventions when necessary. Additionally, changes in indicators such as hemoglobin level and red blood cell count should be closely monitored as early warning indicators for hemolytic anemia and bilirubin elevation.

Acupotomy therapy demonstrates the definite clinical efficacy on knee osteoarthritis (KOA). After reviewing systematically the mechanism studies on acupotomy for KOA over the past 5 years, It is revealed that acupotomy synergistically intervenes in the pathological progression of KOA through multi-target approaches, such as regulating cartilage homeostasis, restoring skeletal muscle function, alleviating synovial inflammatory responses, remodeling subchondral bone, and neuromodulation. But the current research still limits to single-tissue phenotypic observation, and is insufficiency in the in-depth exploration of multi-tissue synergistic interactions and molecular upstream-downstream regulatory mechanisms. Future studies should focus on the inheritance and innovation of acupotomy theory, and integrating multi-omics analytical technologies, artificial intelligence, and novel biochemical detection methods. The mechanism research targets on the interaction mechanisms among tissues, direct effects of acupotomy, immune-inflammatory regulatory mechanisms, and analgesic mechanisms, so as to comprehensively elucidate the therapeutic mechanism of acupotomy for KOA.

BACKGROUND:
T-cell lymphoblastic lymphoma/acute lymphoblastic leukemia (T-LBL/ALL) is an aggressive form of hematological malignancy associated with poor prognosis in adult patients. Histone deacetylases (HDACs) are aberrantly expressed in T-LBL/ALL and are considered potential therapeutic targets. Here, we investigated the antitumor effect of a novel HDAC inhibitor, chidamide, on T-LBL/ALL.
METHODS:
HDAC1, HDAC2 and HDAC3 levels in T-LBL/ALL cell lines and patient samples were compared with those in normal controls. Flow cytometry, transmission electron microscopy, and lactate dehydrogenase release assays were conducted in Jurkat and MOLT-4 cells to assess apoptosis and pyroptosis. A specific forkhead box O1 (FOXO1) inhibitor was used to rescue pyroptosis and upregulated gasdermin E (GSDME) expression caused by chidamide treatment. The role of the FOXO1 transcription factor was evaluated by dual-luciferase reporter and chromatin immunoprecipitation assays. The efficacy of chidamide in vivo was evaluated in a xenograft mouse.
RESULTS:
The expression of HDAC1, HDAC2 and HDAC3 was significantly upregulated in T-LBL/ALL. Cell viability was obviously inhibited after chidamide treatment. Pyroptosis, characterized by cell swelling, pore formation on the plasma membrane and lactate dehydrogenase leakage, was identified as a new mechanism of chidamide treatment. Chidamide triggered pyroptosis through caspase 3 activation and GSDME transcriptional upregulation. Chromatin immunoprecipitation assays confirmed that chidamide led to the increased transcription of GSDME through a more relaxed chromatin structure at the promoter and the upregulation of FOXO1 expression. Moreover, we identified the therapeutic effect of chidamide in vivo .
CONCLUSIONS
This study suggested that chidamide exerts an antitumor effect on T-LBL/ALL and promotes a more inflammatory form of cell death via the FOXO1/GSDME axis, which provides a novel choice of targeted therapy for patients with T-LBL/ALL.
