This study established a high performance liquid chromatography(HPLC) fingerprint of Chuanxiong Rhizoma from different producing areas and screened its potential differential components for producing areas by chemometrics. Furthermore, the content of the above differential components in Chuanxiong Rhizoma from different producing areas was measured and compared. Then, the geoherbalism markers(geo-markers) that can be used to distinguish Dao-di and non-Dao-di Chuanxiong Rhizoma were excavated by chemometrics. In fingerprint studies, a total of 27 common peaks were determined, and the fingerprint similarity for 37 batches of Chuanxiong Rhizoma samples from different producing areas was above 0.968. The orthogonal partial least squares-discriminant analysis(OPLS-DA) was capable of distinguishing Chuanxiong Rhizoma from Sichuan and from three other provinces, as well as Dao-di Chuanxiong Rhizoma(from Dujiangyan) and non-Dao-di Chuanxiong Rhizoma(from other producing areas) in Sichuan province. Meanwhile, 14 potential differential components in Chuanxiong Rhizoma from different provinces and 16 potential differential components in Chuanxiong Rhizoma from different producing areas in Sichuan were screened by the variable importance in projection(VIP) analysis under OPLS-DA. The reference standards were used to identify 10 potential differential components in the common peaks, and subsequent content determination verified that the content of the above 10 potential differential components was different among different producing areas. Then, the OPLS-DA and VIP analysis were performed with the content of the 10 potential differential components as variables. The results showed that Z-ligustilide, chlorogenic acid, and the ratio of butylidenephthalide/senkyunolide A were the geo-markers that can distinguish Chuanxiong Rhizoma from Sichuan and Chuanxiong Rhizoma from Shaanxi, Hebei, and Jiangxi, while Z-ligustilide, n-butylphthalide, and the ratios of Z-ligustilide/senkyunolide A and butylidenephthalide/senkyunolide A were the geo-markers that can distinguish Dao-di Chuanxiong Rhizoma(from Dujiangyan) and non-Dao-di Chuanxiong Rhizoma(from other producing areas) in Sichuan province. This study elucidated the differences in material basis of Dao-di and non-Dao-di Chuanxiong Rhizoma based on fingerprinting and content determination combined with chemometrics, which provides a reference for the study of material basis of Dao-di traditional Chinese medicine.

OBJECTIVES: To investigate the application value of targeted next-generation sequencing (tNGS) in the etiological diagnosis of moderate to severe respiratory distress syndrome (RDS) in neonates. METHODS: A prospective randomized controlled trial was conducted, enrolling 81 term and late-preterm neonates with moderate to severe RDS admitted to Fujian Children's Hospital between December 2023 and December 2024. Patients were randomly assigned to the conventional microbiological test (CMT) group (n=42) or the tNGS group (n=39). For routine pathogen detection, bronchoalveolar lavage fluid was obtained via bronchoscopy, and lower respiratory tract specimens were collected via the endotracheal tube; all specimens underwent culture, and some specimens additionally underwent polymerase chain reaction or antigen testing. In the tNGS group, tNGS was performed in addition to routine pathogen detection on the same specimen types. The detection rate of pathogens, the detection rate of co-infections, and the duration of antibiotic use were compared between the two groups. RESULTS: The pathogen detection rate in the tNGS group (18/39, 46%) was significantly higher than that in the CMT group (8/42, 19%) (P=0.009). The co-infection detection rate was 13% (5/39) in the tNGS group, while no co-infections were identified in the CMT group (P=0.024). Regarding treatment, the duration of antibiotic use in the tNGS group was shorter than that in the CMT group [(12±4) days vs (15±5) days, P=0.003]. CONCLUSIONS tNGS significantly improves the pathogen detection rate in neonates with moderate to severe RDS and offers advantages in the rapid identification of co-infections and reduction of antibiotic treatment duration, suggesting it has clinical utility and potential for wider adoption.

Objective To explore the relationship between lacune of presumed vascular origin and spontaneous HT in elderly patients with AIS.Methods A total of 671 AIS patients hospitalized in our hospital from January 2021 to September 2024 were prospectively recruited.According to the conditions of lacune of presumed vascular origin by the first cranial MRI examination after admis-sion,they were divided into 330 cases with lacune of presumed vascular origin and 341 cases with-out,and based on the re-examination of head CT or MRI during hospitalization,they were also as-signed into a HT group(139 cases)and a non-HT group(532 cases).Multivariate logistic regres-sion analysis was conducted to clarify the correlation between lacune of presumed vascular origin and spontaneous HT in the elderly AIS patients.The incidence of spontaneous HT and the differ-ences in the subtype composition of spontaneous HT were compared between the mild and severe groups of lacune of presumed vascular origin.Results Baseline NIHSS score,atrial fibrillation,white matter lesions,enlarged perivascular spaces,cerebral microbleeds,large-area cerebral infarc-tion,and ratio of lacune of presumed vascular origin were significantly higher in the HT group than the non-HT group[(10(6,13)vs 9(5,12),P=0.000;28.1％vs 18.0％,P=0.009;74.8％vs 56.0％,P=0.000;79.9％vs 57.5％,P=0.000;30.2％vs 16.9％,P=0.000;45.3％vs 13.2％,P=0.000;66.2％vs 44.7％,P=0.000].The incidence of spontaneous HT was significantly high-er in the lacune of presumed vascular origin group than the non-lacune of presumed vascular ori-gin group(27.9％vs 13.8％,P=0.000).Multivariate logistic regression analysis indicated that lacune of presumed vascular origin was an independent risk factor for spontaneous HT after AIS(OR=2.207,95％CI:1.231-3.959).Subtype analysis on spontaneous HT showed that the patients with lacune of presumed vascular origin had the largest proportion among all subtypes than the non-lacune of presumed vascular origin patients.The incidence of spontaneous HT was significantly higher in the severe lacune of presumed vascular origin group than the mild group(38.1％vs 20.9％,P=0.001).HI2 subtype was mainly observed in the severe group with sponta-neous HT,and HI1 subtype was in the mild group with spontaneous HT.Conclusion Lacune of presumed vascular origin is an independent risk factor for spontaneous HT after AIS in elderly patients.The patients with severe lacune of presumed vascular origin are prone to the occurrence and severe spontaneous HT than the mild lacunar patients.

Objective To investigate the difference of spontaneous hemorrhagic transformation(HT)in enlarged perivascular space(EPVS)of different site and various dilation in patients with acute ischemic stroke.Methods A total of 595 patients admitted to our department acute ischemic stroke from January 2021 to June 2024 were recruited in this study.Brain magnetic resonance ima-ging was conducted in all of them within 72 h after admission,and their EPVS status was collect-ed.According to the results of brain MRI,they were divided into EPVS(384 cases)and non-EPVS(211 cases)groups.Based on EPVS site,the EPVS group was further assigned into basal ganglia(135 cases),centrum semiovale(132 cases),and midbrain(117 cases)subgroups,and based on the severity,the group was also into mild(155 cases)and severe(229 cases)subgroups.Brain CT or MRI examination was re-performed on the 7th to 10th day during hospitalization to investigate the intracranial condition,and then spontaneous HT was evaluated.The incidence of spontaneous HT in the EPVS patients of different sites and severity was analyzed and compared.Results The incidence of spontaneous HT was significantly higher in the EPVS group than the non-EPVS group(27.08％vs 8.53％,P＜0.01),and the incidence of spontaneous HT was also obviously higher in the basal ganglia subgroup than the centrum semiovale subgroup and then the midbrain subgroup(40.00％vs 21.97％vs 17.95％,P＜0.01).What's more,the severe subgroup had nota-bly higher incidence of spontaneous HT than the mild subgroup(33.19％vs 18.06％,P＜0.01).Conclusion There is difference in spontaneous HT among acute ischemic stroke patients with EPVS of different site and severity.EPVS in the basal ganglia and of severe level indicates a high-er risk of spontaneous HT,and the two features can better predict the incidence of spontaneous HT.

OBJECTIVE: To investigate the clinical efficacy of Huang'e Capsules in the treatment of type ⅢA chronic prostatitis, and its effects on the levels of the inflammatory cytokines neutrophil elastase (NE), IL-8 and TGF-β1 in the expressed prostatic secretion (EPS) of the patients. METHODS: We selected 120 patients with type ⅢA chronic prostatitis and randomly assigned them to medication with Huang'e Capsules (the trial group, n = 60) or Levofloxacin and Tamsulosin (the control group, n = 60), both for a course of 4 weeks. We obtained the NIH-CPSI scores and the levels of NE, IL-8 and TGF-β1 in the EPS, and compared them between the two groups before and after treatment. RESULTS: Totally, 116 of the patients completed the study, 59 in the trial and 57 in the control group. The overall clinical effectiveness was significantly higher in the trial group than in the control (89.8% vs 77.2%, P<0.05). Compared with the baseline, the patients of the trial group showed significant decreases after treatment in the total NIH-CPSI scores (32.5±7.4 vs 13.2±5.1), pain symptom scores (13.7±3.9 vs 4.2±2.3), urination symptom scores (6.9±2.4 vs 5.1±3.2) and quality of life (QOL) scores (8.3±2.7 vs 3.7±1.5) (all P< 0.05), and so did the controls in the total NIH-CPSI scores (30.8±7.8 vs 13.7±3.9), pain symptom scores (14.2±4.1 vs 7.8±2.9), urination symptom scores (7.1±2.7 vs 4.9±3.4) and quality of life (QOL) scores (8.1±2.4 vs 5.6±1.9) (all P< 0.05), and the decreases were even more significant in the trial than in the control group in the pain symptom and QOL scores ( P< 0.05). The patients of the trial group also exhibited a marked reduction after treatment in the contents of NE (［1135.4±321.5］ vs ［347.6±207.3］ ng/L, P< 0.05) and IL-8 (［974.9±231.6］ vs ［ 431.3±207.2］ ng/L, P< 0.05) but an elevation in that of TGF-β1 (［591.0±172.1］ vs ［1 402.1 ± 221.5］ ng/L, P< 0.05) in the EPS, and so did the controls in the levels of NE (［1052.8±280.3］ vs ［761.1±225.1］ ng/L, P<0.05), (［1007.5±287.7］ vs ［775.7±182.5］ ng/L, P< 0.05), (［607.8±201.3］ vs ［871.3±192.5］ ng/L, P< 0.05), with even more significant improvement in the trial than in the control group (P< 0.05). CONCLUSION Huang'e Capsules has a significant clinical efficacy and safety in the treatment of type IIIA prostatitis, which can effectively relieve the pain and urination symptoms and improve the levels of the inflammatory cytokines NE, IL-8 and TGF-β1 in the patients.

Background::Risk assessment and treatment stratification for three-vessel coronary disease (TVD) remain challenging. This study aimed to investigate the prognostic value of left atrial volume index (LAVI) with the Synergy Between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score II, and its association with the long-term prognosis after three strategies (percutaneous coronary intervention [PCI], coronary artery bypass grafting [CABG], and medical therapy [MT]) in patients with TVD.Methods::This study was a post hoc analysis of a large, prospective cohort of patients with TVD in China, that aimed to determine the long-term outcomes after PCI, CABG, or optimal MT alone. A total of 8943 patients with TVD were consecutively enrolled between 2004 and 2011 at Fuwai Hospital. A total of 7818 patients with available baseline LAVI data were included in the study. Baseline, procedural, and follow-up data were collected. The primary endpoint was major adverse cardiac and cerebrovascular events (MACCE), which was a composite of all-cause death, myocardial infarction (MI), and stroke. Secondary endpoints included all-cause death, cardiac death, MI, revascularization, and stroke. Long-term outcomes were evaluated among LAVI quartile groups. Results::During a median follow-up of 6.6 years, a higher LAVI was strongly associated with increased risk of MACCE (Q3: hazard ratio [HR] 1.20, 95% confidence interval [CI] 1.06-1.37, P = 0.005; Q4: HR 1.85, 95%CI 1.64-2.09, P <0.001), all-cause death (Q3: HR 1.41, 95% CI 1.17-1.69, P <0.001; Q4: HR 2.54, 95%CI 2.16-3.00, P <0.001), and cardiac death (Q3: HR 1.81, 95% CI 1.39-2.37, P <0.001; Q4: HR 3.47, 95%CI 2.71-4.43, P <0.001). Moreover, LAVI significantly improved discrimination and reclassification of the SYNTAX score II. Notably, there was a significant interaction between LAVI quartiles and treatment strategies for MACCE. CABG was associated with lower risk of MACCE than MT alone, regardless of LAVI quartiles. Among patients in the fourth quartile, PCI was associated with significantly increased risk of cardiac death compared with CABG (HR: 5.25, 95% CI: 1.97-14.03, P = 0.001). Conclusions::LAVI is a potential index for risk stratification and therapeutic decision-making in patients with three-vessel coronary disease. CABG is associated with improved long-term outcomes compared with MT alone, regardless of LAVI quartiles. When LAVI is severely elevated, PCI is associated with higher risk of cardiac death than CABG.

Objective To explore clinical effect of precast curvature internal fixation with Kirschner needle in treating forearm fracture in children.Methods From October 2019 to December 2022,32 children with forearm fractures were treated with precast curvature internal fixation with Kirkler's needles,including 25 males and 7 females,aged from 3 to 15 years old with an average of(8.0±0.5)years old,18 patients on the left side and 14 on the right side,24 patients with double fractures of radial and ulna,3 patients with Monteggia fractures,and 4 patients with Galeazzi fractures,and 1 patient with radial neck frac-ture of crooked cap.Operation time,intraoperative blood loss,C-arm fluoroscopy,fracture healing time and complications were recorded,and disabilities of arm,shoulder and hand(DASH)scale and Grace-Eversman forearm double fracture evaluation system were used to evaluate clinical efficacy of precast curvature internal fixation with Kirschner's needle for forearm fracture in children.Resluts All 32 patients were followed up for 2 to 12 months with an average of(7.16±2.51)months.Intraoperative blood loss was(20.68±5.50)ml,C-arm fluoroscopy was(5.80±2.50),and operation time was(24.34±5.10)min,fracture healing time was(8.82±1.62)weeks.Two patients occurred complications,including postoperative rupture of extensor pollicis longus tendon in 1 patient and obvious displacement of fracture caused by rotation of prefabricated curvature Kirschler needle on bone marrow cavity in 1 patient.DASH scores ranged from 0 to 16 scores with an average of(8.32±1.50)scores.According to Grace-Eversman double fracture evaluation system,28 patients got excellent result,2 good and 2 fair.Conclusion The treatment of forearm fracture with Kirschner's needle prefabricated curvature internal fixation has advantages of less trauma,less bleeding,good reduction,stable fixation,fast fracture healing and good functional recovery.

ObjectiveTo investigate the mental health of pediatricians in Guangzhou and its influencing factors， and to provide countermeasures for improving the mental health of pediatricians. MethodsA stratified random sampling method was used to randomly select 400 pediatricians in 11 districts of Guangzhou， and they were surveyed using the Symptom Check List（SCL-90） and the Job Stressor Scale. ResultsThe top three job stressors scored by pediatricians in Guangzhou were external environment （3.23±0.59）， workload （3.19±0.56）， and organizational management （2.74±0.55）. All factor scores were higher than those of the clinician group except for career interest， and the difference was statistically significant （P<0.01）. The number of pediatricians with mental health problems was 109， accounting for 27.25%. All factor scores were higher than the physician norm except for anxiety and paranoia. The correlations between each factor of work stressors and each factor of SCL-90 were positive and statistically significant （P<0.05）， except for two pairs of factors， workload and terror as well as external environment and terror. The results of univariate analysis showed statistically significant differences in the mental health scores of pediatricians with different health status， years of work experience， job satisfaction， job stress， and career prospects （P<0.05）. The results of multiple linear regression showed that health status， years of work experience， professional interest， interpersonal relationship， and doctor-patient relationship were influential factors in the mental health of pediatricians （P<0.05）. ConclusionThe mental health of pediatricians in Guangzhou is unsatisfactory， and the factors affecting them are mainly external objective factors such as workload and organizational management.
