Objective: To analyze the time-related factors influencing daily blood donation attendance at fixed donation sites in Nanjing and the heterogeneity among sites, and to provide evidence for optimizing site layout and operational management. Methods: Based on daily attendance data from 17 fixed donation sites in Nanjing for the full year of 2025, matched with contemporaneous meteorological and air quality data, a two-stage negative binomial generalized linear mixed model (NB-GLMM) was constructed. In the second stage, site-level static characteristics (number of scenic spots, daily operating hours, number of shopping malls, public transport stops, hospitals, universities, and residential buildings) were additionally incorporated. Model comparison was performed using Akaike information criterion (AIC). Significance of random effects was tested by likelihood ratio test, and site-specific random effects were extracted using empirical Bayes estimation. Robustness of the results was verified through residual diagnostics and multiple sensitivity analyses. Results: The first-stage model showed that rainfall was associated with lower attendance (IRR=0.943, P<0.001); holidays were associated with higher attendance (IRR=1.162, P<0.001); Saturdays and Sundays showed higher attendance than Mondays, with the strongest association on Sundays (IRR=1.195, P<0.001). Temperature exhibited a non-linear relationship (linear term P=0.051, quadratic term P=0.036). The joint results of the linear and quadratic terms for temperature suggested a nonlinear relationship between attendance and temperature. After introducing static characteristics in the second stage, the number of scenic spots (IRR=1.372, P=0.008) and daily operating hours (IRR=1.823, P<0.001) were found to be positively associated with attendance, while the numbers of shopping malls, public transport stops, hospitals, universities, and residential buildings showed no significant effects. Conclusion: Daily blood donation attendance at fixed sites in Nanjing is influenced by multiple factors including weather, day of the week, holidays, and site surroundings. Substantial heterogeneity exists among different sites; extended operating hours and more nearby scenic spots are associated with increased attendance.

This study investigated the choroplast genome sequence of wild Atractylodes lancea from Yuexi in Anhui province by high-throughput sequencing, followed by characterization of the genome structure, which laid a foundation for the species identification, analysis of genetic diversity, and resource conservation of A. lancea. To be specific, the total genomic DNA was extracted from the leaves of A. lancea with the improved CTAB method. The chloroplast genome of A. lancea was sequenced by the high-throughput sequencing technology, followed by assembling by metaSPAdes and annotation by CPGAVAS2. Bioiformatics methods were employed for the analysis of simple sequence repeats(SSRs), inverted repeat(IR) border, codon bias, and phylogeny. The results showed that the whole chloroplast genome of A. lancea was 153 178 bp, with an 84 226 bp large single copy(LSC) and a 18 658 bp small single copy(SSC) separated by a pair of IRs(25 147 bp). The genome had the GC content of 37.7% and 124 genes: 87 protein-coding genes, 8 rRNA genes, and 29 tRNA genes. It had 26 287 codons and encoded 20 amino acids. Phylogenetic analysis showed that Atractylodes species clustered into one clade and that A. lancea had close genetic relationship with A. koreana. This study established a method for sequencing the chloroplast genome of A. lancea and enriched the genetic resources of Compositae. The findings are expected to lay a foundation for species identification, analysis of genetic diversity, and resource conservation of A. lancea.

Entinostat plus exemestane in hormone receptor-positive (HR+) advanced breast cancer (ABC) previously showed encouraging outcomes. This multicenter phase 3 trial evaluated the efficacy and safety of entinostat plus exemestane in Chinese patients with HR + ABC that relapsed/progressed after ≥1 endocrine therapy. Patients were randomized (2:1) to oral exemestane 25 mg/day plus entinostat (n = 235) or placebo (n = 119) 5 mg/week in 28-day cycles. The primary endpoint was the independent radiographic committee (IRC)-assessed progression-free survival (PFS). The median age was 52 (range, 28-75) years and 222 (62.7%) patients were postmenopausal. CDK4/6 inhibitors and fulvestrant were previously used in 23 (6.5%) and 92 (26.0%) patients, respectively. The baseline characteristics were comparable between the entinostat and placebo groups. The median PFS was 6.32 (95% CI, 5.30-9.11) and 3.72 (95% CI, 1.91-5.49) months in the entinostat and placebo groups (HR, 0.76; 95% CI, 0.58-0.98; P = 0.046), respectively. Grade ≥3 adverse events (AEs) occurred in 154 (65.5%) patients in the entinostat group versus 23 (19.3%) in the placebo group, and the most common grade ≥3 treatment-related AEs were neutropenia [103 (43.8%)], thrombocytopenia [20 (8.5%)], and leucopenia [15 (6.4%)]. Entinostat plus exemestane significantly improved PFS compared with exemestane, with generally manageable toxicities in HR + ABC (ClinicalTrials.gov #NCT03538171).

[ Abstract ] Objective To explore the effect of 3D print-based navigation module assisted placement of thoracolumbar pedicle screws. Methods From January 2019 to May 2021, we received 70 thoracic and lumbar fracture patients, divided into 3D technical group and conventional method group according to the surgical method, with 35 patients in each group. In the 3D technology group, pedicle screws were placed under the sight of the navigation module, while in the conventional group, pedicle screws were placed under the conventional C-arm fluoroscopy. The amount of intraoperative bleeding and time of C arm were counted in each patient. According to the different number of pedicle screw implantation in each patient, the average amount of blood loss, time and C-arm fluoroscopy times of each screw implantation were compared between the two groups. Ideal screw angles were designed for patients in both groups before surgery. Compared with the preoperative design, the difference between preoperative and postoperative screw angle and head angle was calculated and set as the deviation value. Two sets of data were compared. Visual analogue score(VAS), Japanese Orthopaedic Association (JOA) score, Oswestry disability index(ODI), vertebral height recovery ratio and Cobb’ s angle were compared between the two groups. Results The amount of blood loss, required time and exposure times of C-arm in 3D screw implantation group were significantly lower than those in conventional screw implantation group(P<0. 05); After operation, the deviation of ininclination and head angle in the conventional method group was higher than that in the 3D technique group, and the difference was significant(P<0. 05); The VAS, JOA score, ODI, vertebral height recovery ratio and Cobb’s angle were significantly improved compared with the preoperative groups(P<0. 05); Three months after surgery, the VAS, JOA score, and ODI were not significantly different between the two groups (P>0. 05); In terms of Cobb’s angle and vertebral height recovery ratio, the 3D technique group was better than the conventional method group (P<0. 05). Conclusion The 3D printed navigation module can assist the precise placement of thoracolumbar pedicle screws, shorten the operation time, reduce intraoperative bleeding and c-arm exposure times, facilitate the recovery of the injured vertebral height, improve the efficacy.

This study aims to systematically evaluate the effect of oral Chinese patent medicines on hypertension with network Meta-analysis. Randomized controlled trials on the treatment of hypertension with oral Chinese patent medicine combined with conventional western medicine were retrieved from China National Knowledge Infrastructure(CNKI), Wanfang, VIP, SinoMed, PubMed, EMbase, and Cochrane Library(from establishment of the database to August 2021). Two researchers independently screened the articles, extracted the data, and evaluated article quality. Then R 4.1.0 was employed for data analysis. Finally, 195 eligible articles were screened out, involving 22 546 patients and 18 oral Chinese patent medicines. The results of the network Meta-analysis are as follows. In terms of reducing systolic blood pressure(SBP) and diastolic blood pressure(DBP), Xuesaitong, Qiangli Dingxuan Tablets, Songling Xuemaikang Capsules combined with conventional western medicine are superior. In improving blood lipids, the overall effects of Xinmaitong Capsules, Compound Xueshuantong Capsules, Ginkgo Folium preparations, Yindan Xinnaotong Soft Capsules, and Naoxintong Capsules combined with conventional western medicine are outstanding. In terms of regulating endothelial function, Yindan Xinnaotong Soft Capsules, Xinmaitong Capsules, Zhenju Jiangya Tablets, Compound Danshen Dripping Pills, Xuesaitong with conventional western medicine have certain advantages. As for the safety, the incidence of adverse reactions of conventional western medicine combined with oral Chinese patent medicines is lower than that of conventional western medicine alone. In summary, compared with conventional western medicine alone, the 18 oral Chinese patent medicines combined with conventional western medicine in the treatment of hypertension show advantages in improving blood pressure, blood lipids, and endothelial function. Among them, Xuesaitong, Qiangli Dingxuan Tablets, and Songling Xuemaikang Capsules may be the best oral Chinese patent medicines for lowering blood pressure. The conclusion needs to be further verified by more high-quality studies.

Objective: To explore the safety and feasibility of stereotactic radiation therapy (SBRT) strategy for irradiating porcine ventricular septum, see if can provide a preliminary experimental evidence for clinical SBRT in patients with hypertrophic obstructive cardiomyopathy (HOCM). Methods: Five male pigs (39-49 kg, 6 months old) were used in this study. Pigs were irradiated at doses of 25 Gy (n=2) or 40 Gy (n=3). Delineation of the target volume was achieved under the guidance of 3-dimensional CT image reconstruction, and SBRT was then performed on defined target volume of porcine ventricular septum. Blood biomarkers, electrocardiogram and echocardiography parameters were monitored before and after SBRT. Pathological examination (HE staining, Masson staining) was performed on the target and non-target myocardium at 6 months post SBRT. Results: SBRT was successful and all animals survived to the designed study endpoint (6 months) after SBRT. Serum cardiac troponin T (cTnT) level was significantly higher than the baseline level at 1 day post SBRT, and reduced at 1 week after SBRT, but was still higher than the baseline level(P<0.05). Serum N-terminal pro-B type natriuretic peptide (NT-proBNP) was also significantly increased at 1 day post SBRT (P<0.05) and returned to baseline level at 1 week post SBRT. The serum NT-proBNP level was (249±78), (594±37) and (234±46) pg/ml, respectively, and the cTnT was (14±7), (240±40) and (46±34) pg/ml, respectively at baseline, 1 day and 1 week after SBRT in the 40 Gy dose group. The serum NT-proBNP level was (184±20), (451±49) and (209±36) pg/ml, respectively, the cTnT values ​​were (9±1), (176±29) and (89±27) pg/ml, respectively at baseline, 1 day and 1 week after SBRT in the 25 Gy dose group. Both NT-proBNP and cTnT values tended to be higher post SBRT in the 40 Gy dose group as compared with the 25 Gy dose group, but the difference was not statistically significant (P>0.05). The left ventricular ejection fraction and the left ventricular end-diastolic diameter remained unchanged before and after SBRT (P>0.05). The interventricular septum thickness showed a decreasing trend at 6 months after SBRT, but the difference was not statistically significant ((9.54±0.24) mm vs. (9.82±8.00) mm, P>0.05). The flow velocity of the left ventricular outflow tract, and the valve function and morphology were not affected by SBRT. At 6 months after SBRT, HE staining revealed necrosis in the irradiated target area of ​​the myocardium in the 40 Gy dose group and the 25 Gy dose group, and the degree of necrosis in the irradiated interventricular septum was more obvious in the 40 Gy dose group as compared with the 25 Gy group. The combined histological analysis of the two groups showed that the necrotic area of ​​the irradiated target area accounted for (26±9)% of the entire interventricular septum area, which was higher than that of the non-irradiated area (0) (P<0.05). There was no damage or necrosis of myocardial tissue outside the target irradiation area in both groups. The results of Masson staining showed that the percentage area of myocardial fibrosis was significantly higher in the irradiated target area than non-irradiated area ((12.6±5.3)% vs. (2.5±0.8)%, P<0.05). Conclusion: SBRT is safe and feasible for irradiating porcine ventricular septum.

Objective:To investigate the effect of psychological support during perithrombotic period on post-stroke depression (PSD) in patients with acute ischemic stroke (AIS).Methods:Patients with AIS received intravenous thrombolysis in the Affiliated Lianyungang Hospital of Xuzhou Medical University from January 1, 2021 to July 31, 2021 were enrolled prospectively. The intervention group received one-to-one individual psychological support therapy in the perithrombolytic period on the basis of receiving standard intravenous thrombolytic therapy. At 30 d after onset, Hamilton Depression Scale was used to assess whether PSD occurred. Multivariate logistic regression analysis was used to evaluate the independent influencing factor of PSD. Results:A total of 126 patients with AIS were enrolled, and 86 of them were male (68.25%). Their age was 63.65±10.46 years; 65 were in the intervention group and 61 were in the control group. The incidence of PSD in the intervention group was significantly lower than that in the control group (20.00% vs. 36.07%; χ2=4.049, P=0.044). Multivariate logistic regression analysis showed that psychological intervention (odds ratio [ OR] 0.333, 95% confidence interval [ CI] 0.132-0.838; P=0.020] was an independent protective factor for PSD, while ischemic heart disease ( OR 4.510, 95% CI 1.181-17.217; P=0.028), alcohol consumption ( OR 3.421, 95% CI 1.317-8.888; P=0.012), anticoagulation therapy ( OR 3.145, 95% CI 1.155-8.567; P=0.025) and modified Rankin Scale score before thrombolysis ( OR 1.627, 95% CI 1.142-2.317; P=0.007) were the independent risk factors for PSD. Conclusion:Perithrombolytic psychological support may reduce the incidence of PSD.
