【摘要】 目的 分析慢性乙肝患者血清生化、血常规、血清病毒载量及乙型肝炎标志物与肝组织炎症分级、纤维化分期的相关性,以找到有较好相关性的临床指标；通过肝活检证实临床诊断与病理诊断的符合情况,探讨肝活检的重要性及价值。方法 对2007年6月—2009年8月在传染科行肝穿刺活检的359例慢性乙型肝炎患者的血清丙氨酸氨基转移酶(ALT)、门冬氨酸氨基转移酶(AST)、总胆红素(TB)、白蛋白(ALB)、球蛋白(GLB)等指标,白细胞(WBC)、血小板(PLT)等指标,凝血酶原时间(PT),血清HBV DNA定量及乙肝标志物的不同状态与肝穿病理分级、分期的相关性进行分析；统计慢性乙肝患者临床诊断与病理诊断的符合情况。结果 肝组织炎症分级及纤维化分期之间有一定相关性(Plt;0.05)；血清ALT、AST、ALB、GLB、PT有助于判断肝组织炎症程度(Plt;0.05)；ALB、GLB、WBC、PLT、PT对肝组织纤维化程度的评估有意义(Plt;0.05)；HBV DNA复制水平与肝组织炎症及纤维化无关(Pgt;0.05),但存在负相关的趋势；纤维化程度高的患者HBeAg阴性组较HBeAg阳性组更多(Plt;0.05)。慢性乙型肝炎患者临床与病理诊断总符合率为56.3％。结论 动态监测慢性乙肝患者肝功能、血常规、凝血常规在一定程度上有助于判断疾病的程度,但要确诊肝组织炎症分级及纤维化分期,肝组织病理活检是必需的。

ObjectiveTo explore the diagnostic value of CT-guided percutaneous needle aspiration biopsy (PTNB) for ground-glass opacity (GGO) pulmonary lesions. MethodsA retrospective design was used to collect clinical data of patients with GGO lesions admitted in the Affiliated Hospital of North Sichuan Medical College between Jan. 2009 to Jan 2015. Patients were divided into groups according the lesion size (≤10 mm, 10-20 mm,≥20 mm), length of needle path (≤5 cm, 5-9 cm,≥9 cm) and percentage of GGO component (50%-90%, >90%), respectively. The total and subgroups of sensitivity, specificity, and diagnostic accuracy of CT guided PTNB for diagnosing GGO were calculated and the differences among subgroups were compared using Fisher's exact test. Statistical analysis was conducted by using SPSS 17.0 software. ResultsA total of 60 patients involving 48 malignant and 12 benign lesions were included. The total sensitivity, specificity, and accuracy of CT guided PTNB for diagnosing GGO were 87.5%, 100% and 90%, respectively. There were no significant differences among the subgroups based on the lesion size, length of needle path, and percentage of GGO component (all P values >0.05). ConclusionCT-guided PTNB can be used as one of the diagnostic modalities for lung GGO lesions with a moderate diagnostic value.
Objective To understand the current research status of sentinel lymph node (SLN) biopsy in colorectal cancer. Methods Literatures about the application of SLN biopsy in the field of colorectal surgery were collected and reviewed. Results The results of SLNs biopsy accurately reflected the status of the nodal basin. Focused examination of the SLNs could identify micrometastases that might otherwise had been missed by standard histopathological analysis, thus upstaged this group of patients. Conclusion SLN biopsy represents a new and effective technique to predict the tumor status of regional lymph nodes, which offers a potential alternative to improve the accuracy of tumor staging in colorectal cancer.
ObjectiveTo evaluate the effects of sentinel lymph node biopsy following total mastectomy on immunologic function and prognosis for patients with early breast cancer. MethodsTwo hundred and eleven patients with early breast cancer were entered in this study. In all these cases, the results of sentinel lymph node biopsy were negative. These patients were randomly divided into control group and research group. In 86 cases of control group, the sentinel lymph node biopsy and axillary lymph node dissection following total mastectomy was performed. In 125 cases of research group, the sentinel lymph node biopsy following total mastectomy was performed. The injury of shoulder joint function was analyzed in one year after surgery. The changes of T cell subsets and IL-2 level were detected in the patients respectively on the first day before operation, the second week after operation, and the fourth week after operation. Postoperative fatality rate and postoperative recurrence rate were also observed in two groups. Results①The points of shoulder joint function in the control group and the research group were 72.7±6.5 and 93.5±8.2 respectively, there was an obvious difference (P < 0.05).②The injury degree of shoulder joint function in the research group was significantly lower than that in the control group (P < 0.01).③Compared with the control group, the changes of T cell subsets and the IL-2 level had no significant differences in the research group on day 1 before operation and on week 2 after operation (P > 0.05). On the fourth week after surgery, the CD4+, CD4+/CD8+, and IL-2 level in the research group were obviously higher than those in the control group (P < 0.05). However, the percentage of CD8+ T cell in the research group was significantly lower than that in the control group (P < 0.05).④There were no significant differences for postoperative fatality rate and postoperative recurrence rate between two groups (P > 0.05). ConclusionsSentinel lymph node biopsy for patients with early breast cancer is safe and reliable. With respect to conventional axillary lymph node dissection, it could improve immune function and quality of life after surgery in patients with early breast cancer.
ObjectiveTo explore the risk factors affecting sentinel lymph node (SLN) metastasis in patients with early-stage (N0) breast cancer and establish a predictive model for SLN metastasis, so as to assist in decision-making of axillary surgery in clinical practice. MethodsThe unilateral early-stage breast cancer patients who underwent surgical treatment and SLN biopsy at the Affiliated Hospital of Southwest Medical University from September 2020 to December 2023 were selected as the study subjects. The univariate and multivariable logistic regression analyses were adopted to analyze the relevant risk factors of SLN metastasis, then a predictive model evaluating the risk of SLN metastasis was constructed. The area under receiver operating characteristic curve (AUC) was used to assess the distinguishing ability of risk factors for SLN metastasis. ResultsA total of 351 patients with early-stage breast cancer patients who met the inclusion criteria were enrolled, 136 of whom with SLN metastasis, the SLN metastasis rate was 38.7%. The results of the multivariate logistic regression analysis showed that the maximum tumor diameter >2.5 cm, estrogen receptor (ER) positive, Ki-67 >20%, and vascular invasion were the risk factors affecting SLN metastasis [maximum tumor diameter: OR(95%CI)=1.897(1.186, 3.034), P=0.008; ER positive: OR(95%CI)=2.721(1.491, 4.967), P=0.001; Ki-67 >20%: OR(95%CI)=1.825(1.125, 2.960), P=0.015; vascular invasion: OR(95%CI)=2.858(1.641, 4.976), P<0.001]. The AUC for the SLN metastasis by these four factors was 0.693(0.637, 0.749), with a sensitivity and specificity of 70.59% and 57.21%, respectively. ConclusionsThe results from this study suggest that SLN biopsy is recommended to guide postoperative adjuvant treatment strategies for cN0 early-stage breast cancer patients with a maximum tumor diameter >2.5 cm, ER positivity, Ki-67>20%, and vascular invasion. However, the predictive model constructed based on these four factors in this study has a general ability to distinguish the occurrence of SLN metastasis, then the reasons can be further analyzed in the future.
Objective To systematically review the value of rapid on-site evaluation (ROSE) for diagnosing pulmonary and mediastinal lesions with endobronchial ultrasound (EBUS). MethodsPubMed, EMbase, The Cochrane Library, Web of Science, CNKI, Wanfang, and VIP databases were searched by computer to collect the studies of ROSE and EBUS in the diagnosis of pulmonary and mediastinal lesions from inception to August 2022. Two researchers independently screened the literature, extracted the data, and evaluated the risk of bias in the included studies. Meta-analysis was implemented by RevMan 5.4 and Stata 12.0 software. ResultsA total of 15 studies (9 retrospective studies and 6 prospective studies) with 3 577 patients were included. The meta-analysis results of main outcomes showed that the adequacy of the sample (RD=0.10, 95%CI 0.05 to 0.15, P<0.000 1), overall diagnosis rate (RD=0.07, 95%CI 0.04 to 0.10, P<0.000 1) and the diagnosis rate of the malignant lesion (RD=0.06, 95%CI 0.02 to 0.09, P=0.004) of the ROSE combined with EBUS group were significantly higher than those of the EBUS group. Subgroup analysis showed that the diagnosis rates of pulmonary lesions (RD=0.12, 95%CI 0.08 to 0.17, P<0.000 01) and mediastinal lesions (RD=0.06, 95%CI 0.01 to 0.12, P=0.02) in the ROSE group was significantly higher than those in the EBUS group. The overall diagnosis rate and malignant diagnosis rate of ROSE combined with EBUS were 90% and 92%. The meta-analysis results of secondary outcomes showed that the number of lesions punctures (MD=–1.16, 95%CI –1.89 to –0.43, P=0.002) in the ROSE combined with EBUS group were significantly less than that in the EBUS group; there was no statistical difference in operation time (MD=0.09, 95%CI –5.22 to 5.39, P=0.97) or incidence of complications (RD=–0.06, 95%CI –0.13 to 0.01, P=0.1) between the two groups. Conclusion ROSE can improve the diagnostic efficiency of EBUS in pulmonary and mediastinal lesions, and has the value of the clinical application.
