Background: and Purpose Vertebrobasilar fusiform aneurysms (VBFAs) carry substantial morbidity and mortality, but optimal management for unruptured VBFAs remains unclear. We compared the safety and efficacy of conservative management (CM), stent-assisted coiling (SAC), and flow diverters (FDs) in patients with unruptured VBFAs, focusing on long-term prognosis. Methods: This study included data from a nationwide Chinese cohort of patients with vertebrobasilar dissecting aneurysms. Inverse probability of treatment weighting (IPTW) balanced confounders across groups. The primary outcome was poor prognosis (modified Rankin Scale score >2). Secondary outcomes included aneurysm rupture, ischemic stroke, compression symptoms, and VBFA-related deaths. Logistic regression estimated odds ratios (ORs) and 95% confidence intervals (CIs). Subgroup and sensitivity analyses were performed. Results: Among 1,115 patients with unruptured VBFAs, 838 (median age, 54 years; 655 men) were included. After IPTW, baseline characteristics were balanced. Median follow-up was 54 months. FD was associated with a lower risk of poor prognosis than CM (OR, 0.48 [95% CI, 0.30 to 0.77]; p=0.002), with no difference between CM and SAC. FD also reduced aneurysm rupture (OR, 0.20 [95% CI, 0.07 to 0.60]; p=0.004) and compression symptoms (OR, 0.30 [95% CI, 0.13 to 0.68]; p=0.004) versus CM. Time-to-event analyses further revealed significant differences in vertebral artery lesions and Type I–II VBFAs, whereas no significant differences were observed in basilar or vertebrobasilar junction lesions or in Type III–IV VBFAs. Conclusions Compared with CM, FD was associated with improved long-term outcomes in unruptured VBFAs, particularly in vertebral artery lesions and Type I–II VBFAs, although residual confounding cannot be excluded.

The accurate and timely detection of biochemical coagulation indicators is pivotal in pulmonary and critical care medicine. Despite their reliability, traditional laboratories often lag in terms of rapid diagnosis. Point-of-care testing (POCT) has emerged as a promising alternative, which is awaiting rigorous validation. We assessed 226 samples from patients at the First Affiliated Hospital of Guangzhou Medical University using a Beckman Coulter AU5821 and a PUSHKANG POCT Biochemistry Analyzer MS100. Furthermore, 350 samples were evaluated with a Stago coagulation analyzer STAR MAX and a PUSHKANG POCT Coagulation Analyzer MC100. Metrics included thirteen biochemical indexes, such as albumin, and five coagulation indices, such as prothrombin time. Comparisons were drawn against the PUSHKANG POCT analyzer. Bland-Altman plots (MS100: 0.8206‒0.9995; MC100: 0.8318‒0.9911) evinced significant consistency between methodologies. Spearman correlation pinpointed a potent linear association between conventional devices and the PUSHKANG POCT analyzer, further underscored by a robust correlation coefficient (MS100: 0.713‒0.949; MC100: 0.593‒0.950). The PUSHKANG POCT was validated as a dependable tool for serum and whole blood biochemical and coagulation diagnostics. This emphasizes its prospective clinical efficacy, offering clinicians a swift diagnostic tool and heralding a new era of enhanced patient care outcomes.

Objective:To explore the safety and efficacy of Neuroform Atlas stent assisted coil embolization in intracranial wide-necked aneurysms, and analyze the risk factors for procedure-related complications.Methods:A retrospective analysis was performed; the clinical data of 367 patients with 374 intracranial wide-necked aneurysms accepted Neuroform Atlas stent assisted coil embolization from January 2021 to February 2024 were collected. Clinical prognosis, immediate postoperative and 6-12 months postoperative angiography, and procedure-related complications (including perioperative complications and complications during follow-up) were analyzed. Univariate and multivariate Logistic regression analyses were used to identify the independent risk factors for procedure-related complications.Results:Immediate postoperative Raymond-Roy Occlusion Classification (RROC) grading I was noted in 323 aneurysms (86.4%), grading II in 42 aneurysms (11.2%), and grading III in aneurysms (2.4%). Perioperative complications occurred in 26 patients (7.1%): 19 (5.2%) were ischemic complications, while 7 (1.9%) were hemorrhagic complications. A total of 260 aneurysms (69.5%) underwent follow-up angiography, including 229 aneurysms (88.1%) with RROC grading I, 25 aneurysms (9.6%) with grading II and 6 aneurysms (2.3%) with grading III. During the follow-up, 5 patients (1.9%) developed stent stenosis, but only 1 patient had transient ischemic attack, and all of them had boundless vessel occlusion. At the last follow-up, 10 patients (2.7%) had poor prognosis, including 8 (2.2%) with severe disabilities (7 with modified Rankin Scale [mRS] scores of 3 and 1 with mRS scores of 4), and 2 (0.5%) deaths (mRS scores of 6). Multivariate Logistic regression analysis showed that large aneurysms and posterior circulation aneurysms were independent risk factors for procedure-related complications ( OR=6.299, 95% CI: 1.131-35.094, P=0.036; OR=3.654, 95% CI: 1.478-9.035, P=0.005). Conclusion:Neuroform Atlas stent assisted coil embolization in intracranial wide-necked aneurysms is safe and feasible; patients with large aneurysms and posterior circulating aneurysms are more likely to have procedure-related complications.

Coronavirus disease 2019 (COVID-19) has continued to spread globally since late 2019, representing a formidable challenge to the world's healthcare systems, wreaking havoc, and spreading rapidly through human contact. With fever, fatigue, and a persistent dry cough being the hallmark symptoms, this disease threatened to destabilize the delicate balance of our global community. Rapid and accurate diagnosis of COVID-19 is a prerequisite for understanding the number of confirmed cases in the world or a region, and an important factor in epidemic assessment and the development of control measures. It also plays a crucial role in ensuring that patients receive the appropriate medical treatment, leading to optimal patient care. Reverse transcription-polymerase chain reaction (RT-PCR) technology is currently the most mature method for detecting viral nucleic acids, but it has many drawbacks. Meanwhile, a variety of COVID-19 detection methods, including molecular biological diagnostic, immunodiagnostic, imaging, and artificial intelligence methods have been developed and applied in clinical practice to meet diverse scenarios and needs. These methods can help clinicians diagnose and treat COVID-19 patients. This review describes the variety of such methods used in China, providing an important reference in the field of the clinical diagnosis of COVID-19.

In order to explore the ethical review experience of organ donation and transplantation after the death of citizens, and provide reference value for medical institutions to carry out corresponding ethical review. By using descriptive research, purpose sampling method and the principle of data saturation, 10 members and secretaries of ethics committee on clinical application of organ transplantation technology were finally selected as respondents for semi-structured interviews. The Colaizzi 7-step analysis method was adopted to analyze, summarize and refine the theme. The results showed that the ethical review experience of organ donation and transplantation after the death of citizens included four themes: the responsibilities of ethics committee, the key points of ethics review, the form of ethics review conference and its advantages and disadvantages, and the construction of the ethics committee of organ transplantation. Therefore, there are defects in the ethical review of organ donation and transplantation in medical institutions at present. These can be remedied by enriching elements of the ethical review following the four principles of medical ethics, refining the laws related to organ donation after citizens’ death, constructing a reasonable and efficient pattern of ethical review conference, and establishing a robust and appropriate operation mode of organ transplantation ethics committee.

Objective:To compare the efficacy and safety of injecting different drugs into pleural cavity for treating malignant pleural effusion.Methods:The clinical data of 214 patients with malignant pleural effusion from June 2014 to March 2017 were retrospectively analyzed.According to different treatment method, the patients were divided into simple drainage group(n=26), cisplatin group( n=55), endostar group( n=58), elemene emulsion group( n=30) and erythromycin group( n=45). The recent curative effect, life quality improvement, incidence of adverse reaction, hospitalization expense and the long term survival rate were compared between the two groups. Results:The recent overall effective rates of the five groups were 23.1%(6/26), 49.1%(27/55), 70.7%(41/58), 46.7%(14/30), 73.3%(33/45), respectively, there was statistically significant difference among the five groups(χ 2=24.20, P<0.05). The overall effective rates of the endostar group and the erythromycin group were obviously higher than those of the other three groups(all P<0.05). The live quality improvement rates of the five groups were 30.8%, 58.2%, 84.5%, 56.7% and 88.9%, respectively, there was statistically significant difference among the five groups (χ 2=37.20, P<0.05). The improvement rates of the endostar group and the erythromycin group were obviously higher than those of the other three groups(all P<0.05). In terms of adverse reaction, the incidence of adverse reaction of endostar group was the lowest, only a few patients presented chest pain, weakness, nausea and fever, the incidences were 3.4%, 8.6%, 5.1%, 3.4%, respectively, compared with the other groups, the differences were statistically significant(χ 2=12.40, 10.40, 36.60, 15.0, all P<0.05). The expense of the endostar group [(3 863.2±163.3)CNY] was obviously higher than those of the other groups ( F=124.48, P<0.05). The one-year survival rates of the five groups were 11.5%, 32.7%, 65.5%, 36.7% and 66.7%, respectively, there was statistically significant difference among the five groups (χ 2=28.70, P<0.05). The 2-year survival rates of the five groups were 3.8%, 5.5%, 13.8%, 6.7% and 15.6%, respectively, there was no statistically significant difference among the five groups(χ 2=5.28, P=0.26). The survival period of the four groups injected with different drugs were longer that of the than simple drainage group( F=54.40, P<0.05), the survival periods of the endostar group and the erythromycin group were obviously higher than those of the other groups(all P<0.05). Conclusion:Through injecting endostar or erythromycin into pleural cavity, the recent curative effect and forward survival rate of patients with malignant pleural effusion can be obviously improved, and the life quality of patients can be improved as well, therefore it is worthy of popularizing.Through comparing these two methods, the hospitalization expense of injecting erythromycin is lower, but the incidence rate of adverse reactions including pain and fever is higher, and the incidence rate of adverse reaction of injecting endostar is relatively lower, but the treatment expense is higher.

Objective:To explore the feasibility and safety of minimally invasive surfactant administration (MISA) in preterm neonates with respiratory distress syndrome (NRDS).Methods:In this multicenter prospective randomized controlled trial, 92 preterm infants with gestation age ≤30 weeks and diagnosed with NRDS were enrolled in 8 level Ⅲ neonatal intensive care units (NICU) in Beijing-Tianjin-Hebei Region from 1 st July 2017 to 31 st December 2018. They were randomly assigned to minimally invasive surfactant administration (MISA) group or endotracheal intubation surfactant administration (EISA) group according to random number generated by computer. Infants in both groups received calf pulmonary surfactant preparation at a dose of 70-100 mg/kg. The data of demography, perinatal situation, medication administration, complications, clinical outcomes in the two groups were compared with Chi-square test, Student′s t-test, Mann-Whitney U test or Fisher′s exact test. Results:Among the 92 preterm infants, 53 were males, 39 were females; 47 were in the MISA group (25 males), and 45 were in the EISA group (28 males). The gestational age and birth weight were (29.5±1.2) weeks and (1 271±242) g in all patients, (29.5±1.4) weeks and (1 285±256) g in the MISA group, and (29.6±0.9) weeks and (1 255±227) g in the EISA group. The duration of surfactant infusion and the length of whole procedure in the MISA group were significantly longer than that in the EISA group (60 (18, 270) s vs. 50 (30, 60) s, Z=3.009, P=0.003; 90 (60, 300) s vs. 60 (44, 270) s, Z=3.365, P=0.001). For the outcomes, the incidence of hemodynamically significant patent ductus arteriosus (hsPDA) and bronchopulmonary dysplasia (BPD) were lower in the MISA group than in the EISA group (36% (17/47) vs. 67% (30/45), χ 2=8.556, P=0.003; 26% (12/47) vs. 47% (21/45), χ 2=4.464, P=0.035). Conclusions:Minimally invasive surfactant administration is applicable in preterm infants ≤30 weeks gestational age with NRDS. Although the length of whole procedure is longer than route endotracheal administration, the benefit of decreasing the incidences of hsPDA and BPD outweighs this demerit.
