To compare the efficacy and complication rates of minimally invasive tooth extraction versus traditional extraction in treating impacted lower wisdom teeth. Methods: From January 2023 to September 2025,110 patients with impacted lower wisdom teeth were randomly assigned to an experimental group (55 cases) and a control group (55 cases) using a random number table. The experimental group underwent minimally invasive extraction (high-speed rotary mobile phone tooth splitting + minimally invasive tooth elevator), while the control group received traditional extraction (bone chisel splitting + hammer gap widening). The study compared operative time, postoperative pain (VAS score), mouth opening degree, and intraoperative/operative complications between the two groups. Results: The experimental group showed significantly shorter operative time [(25.38±5.47) min vs (31.65±6.83) min, P<0.001]. Postoperative VAS scores at 24h and 7d were significantly lower in the experimental group [(3.52±1.21) vs (5.87±1.56) points, (0.89±0.65) vs (1.95±0.91) points, both P<0.001], with greater mouth opening degree (P<0.001). The total intraoperative complication rate (1.82%) in the experimental group was significantly lower than the control group (14.55%) (P=0.009), and the postoperative complication rate (3.64%) was also significantly lower than the control group (20.00%) (P=0.022). Conclusion: Compared with traditional tooth extraction, minimally invasive tooth extraction can effectively shorten the operation time, reduce postoperative pain and limited mouth opening, and significantly reduce the risk of intraoperative and postoperative complications. The efficacy and safety are excellent, and it has the value of clinical promotion.

[Abstract]Objective:To explore the impact of refined intraoperative instrument management by operating room nurses on the efficiency and safety of HVR surgery.Methods:The study subjects included 110 patients with VHD who underwent HVR treatment at our hospital from June 2024 to May 2026, along with 22 instrument nurses who participated in the surgeries synchronously. Using the random number table method, the enrolled patients and nurses were divided into a control group (55 patients, 11 nurses) and an experimental group (55 patients, 11 nurses). Nurses in the conventional group implemented routine instrument management during surgery, while nurses in the experimental group implemented zoned and refined instrument management during surgery. The surgical efficiency, perioperative safety events of the two groups of patients, as well as the work efficiency and intraoperative instrument management of the surgeries participated by the nurses in the two groups were compared.Results:Under different instrument management modes, the aortic occlusion time, extracorporeal circulation time, intraoperative non-essential waiting time, and total surgical time of patients in the experimental group were all lower than the control group (t=8.817，5.730，20.609，9.632; P<0.05). The incidence of perioperative safety events in the experimental group was 9.09% (5/55) lower than that in the control group 25.45% (14/55) (x2=5.153; P<0.05). The instrument placement time, instrument delivery response time, number of surgical interruptions, instrument sorting time, and instrument handover time of nurses in the experimental group were lower than those in the control group (t=3.347，6.505，5.971，3.795，5.838; P<0.05). The error rate of nurses in the experimental group was lower than the control group (x2=5.238; P < 0.05).Conclusion:Refined intraoperative zone-specific instrument management by instrument nurses enhances surgical efficiency for HVR patients and reduces the risk of perioperative safety incidents, thereby positively impacting the quality of instrument care provided by nurses and preventing instrument-related adverse events.

目的 对比三维中等权重压缩感知并行采集序列（3D IW-CS-SENSE）与常规并行采集序列（3D IW-SENSE）在膝关节磁共振成像中的扫描时间、图像质量及诊断效能。方法 前瞻性采集100例膝关节磁共振影像。对比两组三维序列的定量指标、主观评分以及对损伤分级的准确率。结果 IW-CS-SENSE序列扫描时间显著缩短（122.0 ± 28.0 s vs 221.0 ± 49.0 s，P<0.001）。IW-CS-SENSE序列信噪比、对比噪声比及显示效果评分均低于IW-SENSE序列（P＜0.001），但IW-CS-SENSE序列的SENSE伪影评分更优（5.00 ± 0.00 vs 4.59 ± 0.62，P<0.001）。两序列对半月板、韧带及软骨损伤分级的准确率均无统计学差异（P值分别为0.33，0.58和0.15）。 结论 3D IW-CS-SENSE序列可显著缩短扫描时间和消除SENSE伪影，同时保持与4倍加速3D IW-SENSE序列相当的诊断效能。

Objective To compare the imaging times, image quality, and diagnostic performance of three-dimensional (3D) intermediate-weighted compressed sensing sensitivity encoding (IW-CS-SENSE) sequence with conventional 3D IW-SENSE sequence in knee MR imaging. Methods MR images of one hundred knees were obtained prospectively. The quantitative indices, qualitative scores, and grading accuracies between the two 3D sequences were compared. Results Imaging times of IW-CS-SENSE sequences were significantly reduced (122.0 ± 28.0 s vs 221.0 ± 49.0 s, P < 0.001). The signal-to-noise ratios, contrast-to-noise ratios, and visualization scores of IW-CS-SENSE sequences were significantly lower than IW-SENSE sequences (P < 0.001), while scores of SENSE artefact for IW-CS-SENSE sequences were superior (5.00 ± 0.00 vs 4.59 ± 0.62, P < 0.001). The accuracies in grading meniscal, ACL, and cartilage tears were comparable between the two sequences (P = 0.33, P = 0.58 and P = 0.15, respectively). Conclusion 3D IW-CS-SENSE sequences can reduce scanning time significantly and eliminate SENSE artefacts, while maintaining the same diagnostic performance as the 4-fold accelerated 3D IW-SENSE sequences.

目的 探讨数字减影血管造影（DSA）在冠状动脉病变诊断中的应用价值，并评估血清学参数相对于DSA金标准的诊断效能。方法 本研究纳入100名确诊为冠心病的患者。病例组为100例DSA确诊的冠心病患者，对照组按1:1比例匹配100例同期接受DSA检查排除冠心病的患者。应用DSA技术分别评估冠心病的狭窄程度及部位等指征。回顾性收集并对比分析两组患者的各项血清学参数（cTnI、CK-MB、hs-CRP、LDL-C、TC），计算血清学指标诊断冠心病的效能，并进一步探究以上评估于入组患者性别亚组间的统计学差异。结果 病例组与对照组在性别、年龄、BMI等基线资料上均衡可比（P > 0.05）。以DSA为金标准，cTnI诊断冠心病的灵敏度为82.0%，特异度为85.0%；hs-CRP的灵敏度为85.0%，特异度为75.0%。 cTnI、hs-CRP水平随冠状动脉狭窄程度加重而显著升高（P < 0.05）。且以上冠心病评价指征于患者性别亚组间均无统计学差异（ P <0.05）。结论 DSA技术可用于冠状动脉病变发生的部位、形态、数目等指征的明确评估，且于不同性别亚组间无统计学差异。血清学参数，尤其是cTnI和hs-CRP，对冠心病具有良好的辅助诊断价值，其水平与病变严重程度相关，可作为DSA检查前的有效筛查工具，为后续的治疗提供重要的参考依据。

Objective: To investigate the clinical value of digital subtraction angiography (DSA) in the diagnosis of coronary artery disease (CAD) and to evaluate the diagnostic performance of serological parameters relative to the DSA gold standard. Methods: A total of 100 patients with confirmed CAD were included in this study. The case group comprised 100 patients with CAD confirmed by DSA, while the control group consisted of 100 age- and sex-matched individuals who underwent DSA during the same period and were excluded from CAD. DSA was employed to assess the degree and location of coronary artery stenosis. Retrospective collection and comparative analysis of serological parameters (cTnI, CK-MB, hs-CRP, LDL-C, TC) were performed between the two groups. The diagnostic efficacy of these serological indicators for CAD was calculated, and subgroup analyses were conducted to explore potential sex-related differences. Results: The case and control groups were comparable in baseline characteristics such as sex, age, and BMI (P > 0.05). Using DSA as the gold standard, the sensitivity and specificity of cTnI for diagnosing CAD were 82.0% and 85.0%, respectively; hs-CRP demonstrated a sensitivity of 85.0% and specificity of 75.0%. Levels of cTnI and hs-CRP increased significantly with the severity of coronary stenosis (P < 0.05). No statistically significant differences were observed between male and female subgroups (P > 0.05). Conclusion: DSA provides definitive assessment of lesion location, morphology, and number in coronary artery disease, with no significant sex-related differences. Serological markers, particularly cTnI and hs-CRP, demonstrate good auxiliary diagnostic value for CAD. Their levels correlate with disease severity and may serve as effective screening tools prior to DSA, offering important reference value for subsequent clinical management.

目的 分析2024年2月至2026年2月郑州人民医院收治的急性下呼吸道感染（ALRTI）患儿的病原体分布情况及其流行病学特征。方法 选取2024年2月—2026年2月于郑州人民医院就诊的193例ALRTI患儿为研究对象，采集患儿咽拭子样本，统计患儿病原体检测结果，比较不同性别、不同年龄段、不同发病季节患儿病原体分布情况。结果 193例患儿中，经病原体检测出阳性患儿165例，总阳性检出率85.49%，检出率最高的前三位为RSV（20.73%）、MP（19.69%）、HRV（15.54%）；婴儿期患儿RSV感染占比（44.83%）最高，其次为HRV感染（20.69%），幼儿期患儿RSV、HRV、MP感染占比（17.31%、17.31%、19.23%）均较高，学龄前、学龄期患儿MP感染占比（33.33%、26.32%）最高，婴儿期患儿混合感染占比（6.90%）较低，学龄前患儿混合感染占比（20.00%）较高；春季时，各病原体分布较均衡，HRV、MP、SP感染占比（14.58%、12.50%、14.58%）均较高，夏季、秋季时，MP感染率（31.82%、28.85%）较高，冬季时，RSV感染率（55.10%）较高，四个季节中混合感染患儿占比较接近，其中秋季感染率（17.31%）相对较高。结论 2024年至2026年郑州人民医院收治的急性下呼吸道感染患儿病原体中，RSV、MP为主要病原体，各呼吸道病原体随患儿年龄段、季节变化存在不同发病高峰，临床应结合实际情况早期鉴别病原体，以指导临床制定针对性治疗方案，改善患儿预后。

Objective To analyze the distribution of pathogens and the epidemiological characteristics of children with acute lower respiratory tract infections (ALRTI) admitted to Zhengzhou People’s Hospital from February 2024 to February 2026. Methods: A total of 193 pediatric patients with ALRTI who visited Zhengzhou People’s Hospital between February 2024 and February 2026 were selected as study subjects. Throat swab samples were collected from the patients, and pathogen testing results were compiled to compare the distribution of pathogens across different genders, age groups, and seasons of onset. Results: Among the 193 children, 165 tested positive for pathogens, resulting in an overall positive detection rate of 85.49%. The top three most frequently detected pathogens were RSV (20.73%), MP (19.69%), and HRV (15.54%); RSV infection had the highest prevalence (44.83%) among infants, followed by HRV infection (20.69%). Among preschoolers, the prevalence of RSV, HRV, and MP infections (17.31%, 17.31%, and 19.23%, respectively) was relatively high. MP infections were most common among preschool and school-age children (33.33% and 26.32%, respectively); the proportion of mixed infections was lower among infants (6.90%) but higher among preschoolers (20.00%); In spring, the distribution of pathogens was relatively balanced, with high proportions of HRV, MP, and SP infections (14.58%, 12.50%, and 14.58%, respectively). In summer and fall, the MP infection rate was high (31.82% and 28.85%, respectively). In winter, the RSV infection rate (55.10%) was high. The proportion of children with mixed infections was relatively similar across the four seasons, with a relatively higher infection rate (17.31%) in autumn. Conclusion: Among the pathogens identified in children with acute lower respiratory tract infections admitted to Zhengzhou People’s Hospital from 2024 to 2026, RSV and MP were the primary pathogens. The incidence peaks of various respiratory pathogens varied according to the children’s age groups and seasons. Clinicians should conduct early pathogen identification based on actual conditions to guide the development of targeted treatment plans and improve patient outcomes.
