Objective:To improve the aqueous solubility, biocompatibility, fluorescence, and sonosensitivity of curcumin, this study aims to transform curcumin into curcumin-derived carbon dots (Cur-CDs) to enhance the efficacy of sonodynamic therapy (SDT) of atherosclerosis (AS).Methods:Cur-CDs were synthesized via a hydrothermal method. The morphology was characterized by transmission electron microscopy, while Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy were applied to analyze the chemical composition and surface functional groups. Optical properties were examined by UV-visible spectrophotometry and fluorescence spectroscopy. Cell proliferation and viability assay and a hemolysis experiment were performed to assess biocompatibility. The sonosensitivity of Cur-CDs was determined by the measurement of reactive oxygen species (ROS) produced by Cur-CDs.To verify the effect of Cur-CDs-mediated SDT on macrophage phenotype, the M1 and M2 macrophage marker genes were detected via real-time fluorescence quantitative polymerase chain reaction. The ability of Cur-CDs in plaque detection was assessed through in vivo fluorescence imaging and ex vivo aortic fluorescence imaging. Atherosclerotic plaque mice were divided into five groups: control group, curcumin group, Cur-CDs group, curcumin + low-intensity pulsed ultrasound (LIPUS) group, and Cur-CDs+ LPIUS group. Aortic Oil red O staining and blood lipid level measurements were conducted to evaluate the therapeutic efficacy of SDT on the plaques.Results:Cur-CDs exhibited a spherical morphology and a distinct lattice structure with the diameter of (1.87±0.35)nm. The aqueous solubility of Cur-CDs was about 10 5 times that of curcumin because of their abundant oxygen-containing hydrophilic functional groups.Cur-CDs at concentrations up to 500 mg/L had no significant impact on cell proliferation and viability, with a negligible hemolysis rate of <1%, indicating good biocompatibility of Cur-CDs. Cur-CDs exhibited a stable and excellent fluorescence with the maximum excitation and emission wavelengths of 420 nm and 530 nm, respectively. Cur-CDs had the potential to be used for plaque fluorescence imaging, with the fluorescence intensity at the plaque being significantly greater than that of curcumin( P<0.01). It was observed that Cur-CDs activated by LIPUS were capable of producing ROS, including 1O 2, ·OH, and ·O 2-, with the total amount of ROS exceeding that of curcumin( P<0.05). Cur-CDs-mediated SDT facilitated the transformation of macrophage phenotype from M1 to M2, with a more pronounced effect than that observed with curcumin-mediated SDT. Oil red O staining revealed the most significant reduction in plaque area and lipid content in the Cur-CDs+ LIPUS group, which was about three times greater than that in the curcumin+ LIPUS group, confirming the excellent efficacy of Cur-CDs-mediated SDT on plaques. Conclusions:The successfully prepared Cur-CDs exhibit superior aqueous solubility, biocompatibility, fluorescence, and sonosensitivity than curcumin, contributing to the significant improvement in sonodynamic efficacy on plaques.

Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

Objective To analyze the composition, population density, seasonal trends, and insecticide resistance monitoring results of vector mosquitoes in Liaocheng City from 2020 to 2022, providing a reference basis for further mosquito control measures. Methods According to the "Implementation Plan for National Vector Biomonitoring", adult mosquito monitoring was carried out using mosquito traps and double-layer stacked nets at two national level monitoring points in Dong’e and Chiping. The Bretu Index method was used for monitoring throughout the city, and the immersion method was used for monitoring mosquito insecticide resistance. The monitoring period for adult mosquitoes was from March to November, and for juvenile mosquitoes was from May to October. Results From 2020 to 2022, a total of 816 mosquito traps were deployed, capturing 4 717 adult mosquitoes with an average density of 5.78 mosquitoes per trap-night. Among them, 4 232 were Culex pipiens pallens, accounting for 89.72% of the total mosquito population, followed by 15 were Anopheles sinensis, accounting for 0.32%; 10 Aedes albopictus, accounting for 0.21%; 460 other mosquito species, accounting for 9.75%. Mosquito density was higher in rural areas compared to urban areas, with the highest density found in livestock sheds, followed by parks, hospitals, farms, and residential areas. Adult mosquito was first observed in May, with the peak activity occurring from June to August. The double-layer net method captures only Aedes albopictus, with an average net trapping index of 2.99 mosquitoes/(net·h), and their activity was concentrated from June to September. The average Brayton Index (BI) from May to October was 15.95, with a peak occurring in July and gradually decreasing after August. Insecticide resistance monitoring found that Culex pipiens pallens in Liaocheng City exhibited low resistance to permethrin, deltamethrin, dithion, and beta cypermethrin, with beta cypermethrin having the highest resistance. Conclusion The dominant mosquito species in Liaocheng City is Culex pipiens pallens, followed by Aedes albopictus. The peak activity of adult and juvenile mosquitoes is concentrated between July and September, showing a distinct seasonal trend of growth and decline, posing a risk of dengue fever outbreaks. Culex pipiens pallens exhibits resistance to some insecticides, and timely measures should be taken to prevent the outbreak of mosquito-borne infectious diseases.

Objectives: To investigated the safety and efficacy of treating patients with acute non-ST-segment elevation myocardial infarction (NSTEMI) and elevated levels of N-terminal pro-hormone B-type natriuretic peptide (NT-proBNP) with levosimendan within 24 hours of first medical contact (FMC). Methods: This multicenter, open-label, block-randomized controlled trial (NCT03189901) investigated the safety and efficacy of levosimendan as an early management strategy of acute heart failure (EMS-AHF) for patients with NSTEMI and high NT-proBNP levels. This study included 255 patients with NSTEMI and elevated NT-proBNP levels, including 142 males and 113 females with a median age of 65 (58-70) years, and were admitted in the emergency or outpatient departments at 14 medical centers in China between October 2017 and October 2021. The patients were randomly divided into a levosimendan group (n=129) and a control group (n=126). The primary outcome measure was NT-proBNP levels on day 3 of treatment and changes in the NT-proBNP levels from baseline on day 5 after randomization. The secondary outcome measures included the proportion of patients with more than 30% reduction in NT-proBNP levels from baseline, major adverse cardiovascular events (MACE) during hospitalization and at 6 months after hospitalization, safety during the treatment, and health economics indices. The measurement data parameters between groups were compared using the t-test or the non-parametric test. The count data parameters were compared between groups using the χ² test. Results: On day 3, the NT-proBNP levels in the levosimendan group were lower than the control group but were statistically insignificant [866 (455, 1 960) vs. 1 118 (459, 2 417) ng/L, Z=-1.25,P=0.21]. However, on day 5, changes in the NT-proBNP levels from baseline in the levosimendan group were significantly higher than the control group [67.6% (33.8%,82.5%)vs.54.8% (7.3%,77.9%), Z=-2.14, P=0.03]. There were no significant differences in the proportion of patients with more than 30% reduction in the NT-proBNP levels on day 5 between the levosimendan and the control groups [77.5% (100/129) vs. 69.0% (87/126), χ²=2.34, P=0.13]. Furthermore, incidences of MACE did not show any significant differences between the two groups during hospitalization [4.7% (6/129) vs. 7.1% (9/126), χ²=0.72, P=0.40] and at 6 months [14.7% (19/129) vs. 12.7% (16/126), χ²=0.22, P=0.64]. Four cardiac deaths were reported in the control group during hospitalization [0 (0/129) vs. 3.2% (4/126), P=0.06]. However, 6-month survival rates were comparable between the two groups (log-rank test, P=0.18). Moreover, adverse events or serious adverse events such as shock, ventricular fibrillation, and ventricular tachycardia were not reported in both the groups during levosimendan treatment (days 0-1). The total cost of hospitalization [34 591.00(15 527.46,59 324.80) vs. 37 144.65(16 066.90,63 919.00)yuan, Z=-0.26, P=0.80] and the total length of hospitalization [9 (8, 12) vs. 10 (7, 13) days, Z=0.72, P=0.72] were lower for patients in the levosimendan group compared to those in the control group, but did not show statistically significant differences. Conclusions: Early administration of levosimendan reduced NT-proBNP levels in NSTEMI patients with elevated NT-proBNP and did not increase the total cost and length of hospitalization, but did not significantly improve MACE during hospitalization or at 6 months.

Purpose:
To identify more accurate predictors of upper urinary tract dilatation (UUTD) in neurogenic bladder (NB) children, we studied the relationship among urodynamic parameters at different bladder filling stages, detrusor leak point pressure (DLPP) and UUTD.
Methods:
A total of 158 children (3–16 years) with NB were included and then divided into 2 groups according to whether their NB diagnosis was complicated with UUTD: the UUTD group (39 patients) and those without UUTD group (control group, 119 patients). The bladder filling phase was divided into 3 equal parts: the early, middle, and end filling stages. The bladder compliance (BC) and detrusor pressure (△Pdet) at each phase and DLPP at the end filling stage were recorded.
Results:
A BC<8 mL/cm H2O both in the middle and end stages is more specific than a BC<9 mL/cm H2O in the end stage (72%, 73%, vs. 66%), and △Pdet >8 cm H2O in the early stage, 20 cm H2O in the middle stage and 25 cm H2O in the end stage are more sensitive than △Pdet >40 cm H2O in the end stage (82%, 85%, 85%, vs. 49%). A DLPP cutoff value of 20 cm H2O showed higher sensitivity for predicting UUTD than 40 cm H2O.
Conclusions
Low BC and a high △Pdet in the middle and end filling stages are more accurate factors than classic indicators for predicting UUTD. In addition, a DLPP value of >20 cm H2O in the end bladder filling stage shows high sensitivity.

Forsythiae Fructus is the dried fruit of Forsythia suspensa and the volatile compounds are its main bioactive components. According to the different harvest periods, F. suspensa can be divided into Qingqiao(mature F. suspensa) and Laoqiao(ripe F. suspensa). To investigate dynamic changes of volatile components in Qingqiao and Laoqiao samples collected at different periods, the present study extracted and analyzed the total volatile oils in Qingqiao and Laoqiao samples(four harvest periods for Qingqiao and two for Laoqiao) by steam distillation method. The results indicated that the content of volatile oils in F. suspensa samples at different harvest periods was significantly different. The content of volatile oils in Qingqiao samples(except those harvested in the first period) was higher than that of Laoqiao, and the content of volatile oils in both Qingqiao and Laoqiao increased with the harvest period. Furthermore, volatile compounds in F. suspensa were qualitatively analyzed by the gas chromatography-mass spectrometry(GC-MS), and 28 volatile compounds were identified. Chemometrics analyses including principal component analysis(PCA) and partial least squares discriminant analysis(PLS-DA) were further applied to explore differential markers and dynamic changes of volatile components in Qingqiao and Laoqiao samples at different harvest periods. Finally, four volatile compounds, including α-pinene, sabinene, β-pinene, and 4-terpenol were selected as potential differential markers. The relative content of α-pinene and 4-terpenol was consistent with that of total volatile oils in the changing trend.

Objective: To investigate the incidence and treatment of perioperative anemia in patients with gastrointestinal neoplasms in Hubei Province. Methods: The clinicopathological data of 7 474 patients with gastrointestinal neoplasms in 62 hospitals in 15 cities (state) of Hubei Province in 2019 were collected in the form of network database. There were 4 749 males and 2 725 females. The median age of the patients was 62 years (range: 17 to 96 years). The hemoglobin value of the first time in hospital and the first day after operation was used as the criterion of preoperative anemia and postoperative anemia. Anemia was defined as male hemoglobin <120 g/L and female hemoglobin <110.0 g/L, mild anemia as 90 to normal, moderate anemia as 60 to <90 g/L, severe anemia as <60 g/L. The t test and χ2 test were used for inter-group comparison. Results: The overall incidence of preoperative anemia was 38.60%(2 885/7 474), and the incidences of mild anemia, moderate anemia and severe anemia were 25.09%(1 875/7 474), 11.37%(850/7 474) and 2.14%(160/7 474), respectively. The overall incidence of postoperative anemia was 61.40%(4 589/7 474). The incidence of mild anemia, moderate anemia and severe anemia were 48.73%(3 642/7 474), 12.20%(912/7 474) and 0.47%(35/7 474), respectively. The proportion of preoperative anemia patients receiving treatment was 26.86% (775/2 885), and the proportion of postoperative anemia patients receiving treatment was 14.93% (685/4 589). The proportions of preoperative anemia patients in grade ⅢA, grade ⅢB, and grade ⅡA hospitals receiving treatment were 26.12% (649/2 485), 32.32% (85/263), and 29.93% (41/137), and the proportions of postoperative anemia patients receiving treatment were 14.61% (592/4 052), 22.05% (73/331), and 9.71% (20/206). The proportion of intraoperative blood transfusion (16.74% (483/2 885) vs. 3.05% (140/4 589), χ²=434.555, P<0.01) and the incidence of postoperative complications (17.78% (513/2 885) vs. 14.08% (646/4 589), χ²=18.553, P<0.01) in the preoperative anemia group were higher than those in the non-anemia group, and the postoperative hospital stay in the preoperative anemia group was longer than that in the non-anemia group ((14.1±7.3) days vs. (13.3±6.2) days, t=5.202, P<0.01). Conclusions: The incidence of perioperative anemia in patients with gastrointestinal neoplasms is high. Preoperative anemia can increase the demand for intraoperative blood transfusion and affect the short-term prognosis of patients. At present, the concept of standardized treatment of perioperative anemia among gastrointestinal surgeons in Hubei Province needs to be improved.

ObjectiveThis study investigated the mechanism of Wenjingtang in the prevention and treatment of endometriosis (EMT) from the perspective of regulating hypoxia stress and mitochondrial function. MethodPrimary human endometrial stromal cells (ESCs) form ectopic endometrial tissues were isolated and cultured, the cells were divided into control group (Control), 5% control serum group (5% KBXQ), 10% control serum group (10% KBXQ), 5% Wenjingtang serum group (5% WJTXQ) and 10% Wenjingtang serum group (10% WJTXQ). ESCs in different groups were detected for proliferation by methyl thiazolyl tetrazolium (MTT) assay, mRNA and protein expression of hypoxia inducible factor-1α (HIF-1α) by real-time fluorescent quantitative polymerase chain reaction (Real-time PCR) and Western blot analysis, mitochondrial ultrastructure by transmission electron microscope, mitochondrial function [mitochondrial membrane potential, mitochondrial membrane potential(MMP) and cytochrome C(Cyt C) content] and apoptosis (cell membrane permeability, nuclear fluorescence intensity, nuclear size and cell counts) by high content screening (HCS) assay, apoptosis rate by flow cytometry, and proteins of B-cell lymphoma-2 (Bcl-2) associated X (Bax), Bcl-2 and cleaved cysteinyl aspartate specific proteinase-3 (cleaved Caspase-3) by Western blot. ResultCompared with Control group, the 5% KBXQ and 10% KBXQ groups showed increased cell viability (P<0.01), there was no significant change in HIF-1α mRNA and protein expression, transmission electron microscopy showed that the mitochondrial cristae were obvious and the inner and outer membranes of mitochondria were clear, HCS multichannel fluorescence staining showed that there were no significant changes in the expression of MMP, Cyt C and cell membrane permeability, and the nuclei showed uniform light staining, there were no significant changes in apoptosis rate, cleaved Caspase-3 protein expression and Bax/Bcl-2 ratio. Compared with Control group and corresponding concentration KBXQ group, the 5% WJTXQ and 10% WJTXQ group showed decreased cell viability (P<0.01) and HIF-1α mRNA and protein levels (P<0.05,P<0.01), the ultrastructure of mitochondria was destroyed, some mitochondria were swollen and the cristae were blurred, moreover, decreased MMP and up-regulated Cyt C release (P<0.05,P<0.01), increased cell membrane permeability (P<0.01), and apoptosis characteristics included nuclear pyknosis, DNA agglutination in nucleus and decrease of cell numbers were observed (P<0.05,P<0.01), increased apoptosis rate (P<0.01), which was consistent with the results of HCS analysis, and up-regulated expression levels of cleaved Caspase-3 protein and Bax/Bcl-2 ratio (P<0.05,P<0.01). ConclusionIn conclusion, the results suggest that Wenjingtang can improve hypoxia stress via down-regulating HIF-1α expression in ectopic ESCs, and inhibit cell proliferation, reduce mitochondrial biological activity and induce apoptosis, which might be the internal mechanism of Wenjingtang in preventing and treating EMT.
