目的 探讨在丙泊酚诱导麻醉的改良电休克治疗中脑双频谱指数(BIS)与动作发作时间的关系，以及其他因素对电休克动作发作时间的影响。 方法 2012年4月－5月，记录28名患者的107次治疗中的不同时刻脑双频谱指数（BIS）值诱导前、睫毛反射消失时、治疗前即刻、动作发作结束即刻、动作发作结束后60 s）、麻醉药物剂量、动作发作时间及治疗不良反应，并根据动作发作时间将治疗分为A组（治疗无效组，动作发作时间＜17 s）和B组（治疗有效组，动作发作时间≥17 s）。探讨不同时刻BIS值与癫痫发作时间的关系并比较A、B组之间BIS值、麻醉药物剂量差异。 结果 两组间睫毛反射消失时及治疗前即刻BIS值差异有统计学意义（P＜0.05）。动作发作时间与治疗前即刻BIS值呈正相关（r=0.245，P=0.012），与治疗次数呈负相关（r=−0.283，P=0.004）。 结论 治疗前即刻BIS值与动作发作时间呈正相关，因此，此时的BIS值也许可以作为预测动作发作时间长短的指标。
ObjectivesTo evaluate the quality of guidelines on nutrition in liver disease from 2017 to 2019, and to interpret these guidelines so as to provide references for clinical practice.MethodsComputer-assisted literature searches in CNKI, VIP, WanFang Data, Medline (Ovid), The Cochrane Library, PubMed and Medlive databases were performed by two reviewers for guidelines on nutrition in liver disease from January 2017 to July 2019. Two reviewers extracted data and assessed the methodological quality of the included guidelines using AGREE II, separately. Meanwhile, the intraclass correlation coefficient (ICC) was used to assess the degree of consistency.ResultsFour guidelines were included with 2 from China and 2 from Europe. Their average standardised scores in the 6 domains of scope and purpose, stakeholder involvement, rigour of development, clarity, applicability and independence were 79.17%, 71.53%, 78.13%, 85.42%, 61.98% and 43.75%, respectively. The Chinese and European guidelines had similar recommendations for energy and other nutrients, apart from differences in recommendations for protein intake. The European guidelines considered that restricting protein intake was not beneficial for patients with hepatic encephalopathy, while the Chinese guidelines argued that patients with severe hepatic encephalopathy were required to reduce or limit their protein intake.ConclusionsAll 4 guidelines are of average quality and are required to be strengthened in the ‘independence’ domain. Currently, the only consensus on nutrition therapy for liver disease and guidelines on nutrition in end-stage liver disease are available for references in China, with lower quality scores than that of the European guidelines. Therefore, the evidence-based guidelines on nutrition in liver disease should be developed by Chinese national conditions as soon as possible to provide references for clinicians, nurses and clinical nutritionists, enableing them to implement nutrition screening, evaluation, nutritional therapy and follow-up management for patrents with liver disease.
目的 建立荣保灵芝1号子实体及其孢子粉中灵芝酸A的含量测定方法。 方法 采用高效液相色谱法，UltimateTM XB-C18色谱柱，柱温：25℃，流速：0.800 mL/min，检测波长：254 nm，流动相为乙腈(B)-0.1%冰乙酸水溶液(A)，梯度洗脱。 结果 灵芝酸A的线性范围是0.010～1.200 mg/mL（r=0.9998），平均回收率为100.55%，相对标准偏差为1.70%（n=6），子实体中灵芝酸A的含量范围在2.221 7～3.531 1 mg/g，孢子粉中灵芝酸A的含量范围在0.167 2～0.742 9 mg/g。 结论 该方法简便，专属性和重复性好，对连续3年采集的荣保灵芝1号子实体和孢子粉中的灵芝酸A进行测定，其含量都随年份的增加而增加。
ObjectiveTo analyze the relation between marital status and prognosis of patients with colorectal cancer (CRC) in the Database from Colorectal Cancer (DACCA). MethodsThe DACCA version selected for this data analysis was updated on January 13, 2023. The data items analysis included the age, gender, marital status, tumor location, tumor property, pathological TNM (pTNM) stage, survival status, and survival time. According to the marital status, the patients were assigned into five marital statuses: the first marriage, unmarried, divorced, remarriage, and widowed groups. The overall survival (OS) and disease specific survival (DSS) of the 5 marital statuses were analyzed, and then the risk factors affecting OS and DSS were analyzed by the Cox proportional hazards regression model. ResultsA total of 7 373 data were obtained from the DACCA according to the screening conditions, of which 6 696 (90.8%) were first marriage, 108 (1.5%) were unmarried, 198 (2.7%) were divorced, 22 (0.3%) were remarriage, and 349 (4.7%) were widowed. The OS and DSS curves had no statistical differences among the CRC patients with 5 marital statuses (χ2=2.692, P=0.611; χ2=2.927, P=0.570). The 3-year cumulative overall survival rate and disease specific survival rate among the 5 marital status patients had statistical differences among the patients with five marital statuses (χ2=24.65, P<0.001; χ2=18.63, P=0.001), further pairwise comparison showed that the 3-year cumulative overall survival rate and disease specific survival rate in the CRC patients with first marriage were higher than those in the widowed patients (Z=3.36, P<0.01; Z=3.02, P<0.01). The multivariate analysis results by the Cox proportional hazards regression model did not find the marital status was associated with the OS and DSS (P>0.05). ConclusionsFrom the real-world analysis results of this study, it is found that 3-year cumulative overall survival rate and disease specific survival rate in patients with first marriage are higher as compared with widowed patients. It is necessary to pay more attention to the long-term follow-up of CRC patients in unmarried or widowed status.
Objective To analyze the relation between the marital status of patients with colorectal cancer and neoadjuvant therapy (NAT) regimen decision-making and outcomes in the current version of the Database from Colorectal Cancer (DACCA). Methods The version of DACCA selected for this analysis was updated on June 29, 2022. The patients were enrolled according to the established screening criteria and then assigned to 5 groups: the unmarried, married, divorced, remarried and widowed groups. The differences in the NAT regimen decision-making and changes of symptom, imaging, and cancer markers in these 5 groups were analyzed. Results A total of 3 053 data that met the screened criteria were enrolled. The results of statistical analysis reflected that the difference in the constituent ratio of patients chosen NAT strategies among 5 groups was obviously statistically significant (χ2=27.944, P=0.004), showing that remarried patients were inclined to adopt combined target drug. No statistical differences were found in changes of symptom (H=5.717, P=0.221), image (H=8.551, P=0.073), and cancer markers (H=11.351, P=0.183) of the 5 groups after NAT. Conclusion Through analysis of DACCA data, it is found that in the selection of NAT strategy for colorectal cancer, more married and remarried patients tended to choose chemotherapy combined target drug regimen.
