新辅助免疫治疗在局部晚期直肠癌中应用循证证据

错配修复功能缺陷(deficient mismatch repair,dMMR)是目前公认的预测免疫检查点抑制剂(immune checkpoint inhibitors,ICIs)疗效的生物标志物,国内外指南已推荐dMMR实体瘤患者一线治疗选择免疫治疗。在直肠癌中,仅5%患者为dMMR/高度微卫星不稳定(microsatellite instability-high,MSI-H),绝大多数为“免疫沙漠型”或错配修复功能完整(mismatch repair proficient,pMMR)/微卫星稳定(microsatellite stabilization,MSS),即对ICIs反应欠佳。因此免疫药物与新辅助放化疗的协同作用是近些年基础和临床研究的热点,并且有较多Ⅱ/Ⅲ期免疫全新辅助治疗(immuno-total neoadjuvant therapy,iTNT)相关临床试验涌现,局部进展期直肠癌(locally advanced rectal cancer,LARC)管理模式也开始进入非手术治疗时代。dMMR/MSI-H型LARC患者新辅助免疫疗法效果显著,有望让患者在后续治疗中豁免手术和放化疗从而选择观察等待策略;对于pMMR/MSS型LARC,目前初步认定ICIs从初始作为后线姑息方案前移到一线选择策略以及继续开展大型临床试验。但iTNT在LARC中应用最佳模式尚无定论,但短程放疗序贯新辅助化疗联合免疫药物可能获得良好短期疗效。寻找其它新的生物标志物,可能会鉴定出部分对iTNT敏感的pMMR/MSS型患者(尤其是低位直肠癌)。未来LARC治疗策略需结合患者临床复发危险度分层和器官保留意愿两方面考虑,实现分层精准治疗。本文将对LARC中iTNT的相关研究背景、基础和临床研究进展以及存在问题等进行综述。

Clinical Application Value of Combined Detection of CG and TBA in Differential Diagnosis of Hepatobiliary System Diseases

Objective: To understand the clinical value of combined detection of cholyglycine CG and TBA in differential diagnosis of hepatobiliary diseases. Methods: Serum samples from 50 healthy people were collected as healthy control group. According to the latest disease diagnosis and treatment plan, 58 cases of HBV asymptomatic carrier group, 17 cases of viral hepatitis group, 49 cases of cirrhosis group, 50 cases of primary liver cancer group and 50 cases of other hepatobiliary diseases groups were collected respectively. The concentration levels of cholyglycine and total bile acid in each group were detected, and the differences among each group were compared. Results: By statistical analysis, serum CG concentration in viral hepatitis group, cirrhosis group, primary liver cancer group and other hepatobiliary diseases group was significantly higher than that in asymptomatic HEPATITIS B carriers and healthy control group, the differences were statistically significant (p 0.05). There was no significant difference in CG concentration among viral hepatitis group, liver cirrhosis group, primary liver cancer group and other hepatobiliary diseases group (p > 0.05). The serum TBA levels of asymptomatic carriers, viral hepatitis group, cirrhosis group, primary liver cancer group and other hepatobiliary system diseases group were significantly higher than those of healthy control group, the difference was statistically significant, p 0.05. Conclusion: Serum CG expression can not only detect liver lesions, but also distinguish different liver lesions. The positive rate of CG combined with TBA detection in patients with hepatobiliary diseases is significantly higher than that of single CG index detection. CG combined with TBA detection can significantly improve the sensitivity and accuracy of the diagnosis of hepatobiliary diseases, which is worthy of popularization and application.

Urine Cystatin C Determination in the Establishment of Reference Interval in the Diagnosis and Treatment of Renal Injury

Objective: To establish the diagnostic concentration range of urine cystatin C and the control level of urine cystatin C for patients with renal injury, and to help promote the establishment of standardization of urine cystatin C detection. Methods: 150 urine specimens and blood specimens from kidney injury patients and healthy people were collected, and stored in the refrigerator at -80°C for later use. After the specimens were collected, they were uniformly tested. Comparing the difference of blood and urine cystatin C between the kidney injury group and the healthy control group, the application value of urine cystatin C in the diagnosis and treatment of kidney injury was put forward. Results: The concentrations of cystatin C in urine and blood of renal injury group were 1.04 ± 2.14 mg/L and 1.94 ± 2.36 mg/L respectively;the concentrations of cystatin C in urine and blood of healthy control group were 0.11 ± 0.05 mg/L and 0.83 ± 0.20 mg/L respectively. The urine and blood cystatin C of the kidney injury group were significantly higher than those of the healthy control group. Compared the results of the two groups, the t values were 5.3210 and 5.7399, respectively. The P value is 0.0000;the difference is statistically significant;in comparison of urine and blood cystatin C in the kidney injury group, the value is that t = 3.4600, P = 0.0003;in comparison of urine and blood cystatin C in the healthy control group, the value is that t = 42.7744, P = 0.0000. By investigating the urine cystatin C concentration of patients with kidney injury, whether it is kidney injury or healthy controls, urine cystatin C is significantly lower than blood cystatin C. Conclusion: According to the results of this study, the concentration of urinary cystatin C in the healthy control group is 0.11 ± 0.05 mg/L. The reference interval of urinary cystatin C proposed in this study is 0.06 - 0.16 mg/L, which can be established by comprehensive multi center research. Through a multi-center study of the baseline level of urinary cystatin C in patients with renal injury, the diagnostic concentration interval of urinary cystatin C and the control level of urine cystatin C for renal injury patients were established.

Analysis and Management of Adverse Drug Reactions after Injection of Amphotericin B in AIDS Patients with Fungal Infection

Objective: To understand the condition of adverse drug reactions and the treatment procedures of amphotericin B for injection in patients with AIDS complicated with fungal infection. Methods: For the research object, a retrospective analysis of adverse reactions of amphotericin B injection in 121 patients of AIDS complicated with fungal infection was reported in our hospital from October 2017 to June 2021 to observe the adverse drug reactions of patients after treatment with amphotericin B for injection, 87 cases with general degree (regarded as the general group) and 34 cases with serious degree (regarded as the serious group), and analyze the general data, medication and course of disease of the two groups for symptomatic treatment. Results: Adverse reactions such as hypokalemia, abnormal liver function, renal impairment, leucopenia and drug fever were more common in the two groups, and there were also many adverse reactions such as bone marrow suppression, rash, anemia, thrombocytopenia, nausea, vomiting, fatigue, dizziness, pruritus, angina pectoris, vertigo, abdominal pain and diarrhea. The rates of leukopenia and drug fever in general group were significantly lower than those in severe group (P < 0.05);in the dose of amphotericin B used, the rate of using 25 mg and more than 25 mg in the general group was significantly lower than that in the severe group (P < 0.05). After symptomatic treat-ment, most patients have improved, and a few are unknown or have not improved. Con-clusion: Amphotericin B for injection has great side effects and will cause different degrees of adverse drug reactions. The dose of amphotericin B for clinical treatment should be ad-justed and disposed according to the adverse reactions to avoid serious consequences.
