Objective To analyze the pathways, biomarkers and diagnostic genes of systemic sclerosis associated interstitial lung disease (SSc-ILD) using bioinformatics. Methods SSc-ILD related gene data sets from April to June 2023 were downloaded from the Gene Expression Omnibus database for differential analysis and enrichment analyses including gene ontology analysis, Kyoto Encyclopedia of Genes and Genomes analysis, disease ontology analysis, and gene set enrichment analysis. Least absolute shrinkage and selection operator regression and support vector machine algorithms were applied to screen and take the intersection to get the diagnostic genes and validate the results. Disease-related data were analyzed by immune cell infiltration. Results A total of 178 differential genes were obtained, and enrichment analyses showed that they were related to 5 signaling pathways and associated with 3 diseases. The diagnostic genes screened were TNFAIP3, ID3, and NT5DC2, and immune cell infiltration showed that the diagnostic genes were associated with plasma cells, resting mast cells, activated natural killer cells, macrophage M1 and M2, resting dendritic cells, and activated dendritic cells. Conclusion The screened diagnostic genes and immune cells may be involved in the development of SSc-ILD.
目的 回顾性研究老年系统性红斑狼疮（SLE）患者合并感染的危险因素。 方法 选取1995年1月－2009年12月间在四川大学华西医院确诊为SLE，起病年龄为50周岁以上的158例患者，收集性别、临床表现、疾病活动度、实验室检查指标、合并症以及并发症等进行单因素分析或多因素非条件logistic回归分析。 结果 所纳入的158例患者中，合并感染53例（占33.5%），采用单因素分析显示疾病活动性（P=0.001）、低蛋白血症（P=0.030）、糖尿病（P=0.003）、肺间质病变（P=0.000）与老年SLE患者感染发生有关。经logistic回归分析显示，疾病活动性（OR=7.533，P=0.000）、肺间质病变（OR=19.762，P=0.000）、糖尿病（OR=6.862，P=0.025）是老年SLE患者感染发生的危险因素。 结论 积极控制老年SLE的疾病活动度，减少危险因素的发生是控制老年SLE患者并发感染的有效手段。
ObjectiveTo investigate the effect and predictive value of systemic inflammatory markers on pathological complete response (pCR) after neoadjuvant chemotherapy (NACT) for locally advanced breast cancer (LABC). MethodsThe clinicopathologic data of female patients with LABC who received NACT and radical surgical resection in the Department of Breast Surgery, Affiliated Hospital of Southwest Medical University from February 2019 to February 2022 were retrospectively analyzed. The factors affecting pCR after NACT were analyzed by the multivariate logistic regression and the prediction model was established. The efficiency of the prediction model was evaluated by receiver operating characteristic (ROC) curve and area under the ROC curve (AUC). ResultsA total of 98 patients were gathered, of which 29 obtained pCR, with a pCR rate of 29.6%. The multivariate analysis of binary logistic regression showed that the patients with non-menopausal status, negative estrogen receptor (ER), chemotherapy+targeted therapy, and systemic immune-inflammation index (SII) <532.70 (optimal critical value) were more likely to obtain pCR after NACT (P<0.05). The prediction model was established according to logistic regression analysis: Logit (P)=0.697–2.974×(menopausal status)–1.932×(ER status)+3.277×(chemotherapy regimen)–2.652×(SII). The AUC (95%CI) of the prediction model was 0.914 (0.840, 0.961), P<0.001. ConclusionsIt is not found that other inflammatory indicators such as neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and lymphocyte-to-monocyte ratio are associated with pCR after NACT. But SII is an important predictor of pCR after NACT for LABC and has a good predictive efficiency.
ObjectiveTo examine the high-risk factors and prognosis of patients with superior interlobar lymph nodes (11s nodes) metastasis in non-small cell lung cancer (NSCLC) located in the right middle or lower lobe.MethodsThe clinical data of 157 patients with NSCLC in the right middle or lower lobe from January 2015 to July 2020 in our hospital were retrospectively analyzed, including 98 males and 59 females aged 23-86 (60.01±10.58) years. The patients underwent lobectomy and systemic lymph node dissection along with dissection of 11s nodes. They were divided into a 11s (+) group and a 11s (–) group according to whether the 11s nodes were involved.ResultsThere were 31 patients with invasion in the 11s nodes, and the overall incidence of metastasis was 19.75%, including 13.64% with middle lobe tumors and 20.74% with lower lobe tumors. The 2R+4R nodes involvement was the influencing factor associated with 11s nodes metastasis (P=0.026). The 7th nodes and the inferior mediastinal lymph nodes involvement were high-risk factors affecting the prognosis of patients (P<0.05). The 11s nodes metastasis had nothing to do with the location of the tumor, and it was not an independent factor affecting disease-free survival.ConclusionThe 11s nodes may be a transit for 2R+4R nodes metastasis in the right middle or lower lobe lung cancer, and the 11s nodes should be cleared in the surgical treatment for NSCLC in either the middle or lower lobe of the right lung. The influencing factors for disease-free survival after surgery for lung cancer in the right middle or lower lobe are the metastasis of the subcarinal lymph nodes and the inferior mediastinal lymph nodes.
摘要:目的:探讨系统性红斑狼疮（SLE）肝损害的临床特点、肝损害发生率与SLE的病情严重程度的关系。方法:对98例SLE的临床资料进行分析,收集所有研究对象的临床资料,对肝损害组(30例)的症状与体征、病情程度、肝功能指标、影像学检查结果进行数据分析,并将其部分生化及免疫学指标与无肝损害组(68对照组)进行比较。结果:SLE患者中SLE肝损害的发生率为30.61%。肝损害组中,病情重度16例(53.33%),17例患者(56.67%)无明显自觉症状,以ALT、AST轻中度升高为主。7例患者肝脏B超异常。肝损害组患者的白细胞值明显低与无肝损害组(Plt;0.05)。而2组的血红蛋白、血小板、CRP、ESR、抗核抗体、抗dsDNA抗体、IgG、补体3等比较差异均无统计学意义(P均gt;0.05)。11例患者接受肾上腺皮质激素(激素)、免疫抑制剂(环磷酰胺、甲氨蝶呤)等药物治疗,9例在出院时复查肝功能正常或好转,另2例肝功能无明显改善;19例患者在接受激素、免疫抑制剂治疗的同时,给予护肝治疗,15例出院复查肝功能正常或好转,另4例无明显改善。而对照组68例中病情重度8例(11.76%)。结论:肝脏是SLE常见累及的靶器官之一,SLE肝损害的临床表现缺乏特异性,以轻至中度肝细胞损害多见,肝损害发生率与SLE病情严重程度成正相关、与SLE的近期预后无关、与长期预后有待进一步研究。Abstract: Objective: To discuss the relationship between the clinical characteristic, The incidence of liver damage and the severity of SLE. Methods: Carries on the mathematical analysis to 98 example SLE clinical material, the collection all object of study clinical material, to liver harm group (30 examples) the symptom and the symptom，Severity the liver function target， the phantom study inspection result carries on the mathematical analysis, and (68 control groups) carries on its part of biochemistry and the immunology target with the nonliver harm group the comparison.Results: In the SLE patient the SLE liver harms the formation rate is 30.61%.In liver harm group, severe illness in 16 cases (53.33%), 17 example patient (56.67%) not obvious subjective symptom, by ALT, AST light moderate ascension primarily.7 example patient liver B ultra exceptionally.The liver harm group patient’s white blood cell value is lower than the nonliver harm group obviously (Plt;0.05), but 2 groups of hemoglobins, the blood platelet, CRP, ESR, the antinuclear immune body, the antidsDNA immune body, IgG, the complement 3 and so on the comparison differences do not have statistics significance (Pgt;0.05). 11 example patients accept the adrenal cortex hormone (hormone), the immunity inhibitor (endoxan, armor ammonia pterin) and so on the medicine treatments, 9 examples when out of hospital reexamines the liver function normal or the change for the better, another 2 example liver function improves not obviously; 19 example patients while accept the hormone, immunity inhibitor treatment, gives protects the liver treatment, 15 example out of hospital reexamination liver function normal or change for the better, another 4 examples improve not obviously. While the control group, 68 cases of severe illness in 8 cases (11.76%).Conclusion: The liver is one of target organs which SLE implicates common, the SLE liver harm. the clinical manifestation lacks the specificity, by sees lightly to the moderate liver cell harm,The incidence of liver damage and SLE severity is positively correlated with shortterm prognosis of SLE has nothing to do with the longterm prognosis remains to be further studied.
ObjectiveTo study the perioperative treatment of total hip arthroplasty (THA) for avascular necrosis of the femoral head (ANFH) in systemic lupus erythematosus (SLE) patients. MethodsThe clinical data of 27 patients with SLE and ANFH, who underwent 40 THAs between August 2009 and November 2012 were retrospectively analyzed. There were 5 male and 22 female patients, and the average age of the patients at surgery was 40 years ranging from 21 to 66 years. Fourteen cases had unilateral THA and 13 had bilateral THA. The combined disease included 2 cases of hypertension, 3 chronic bronchitis, 1 autoimmune liver disease and hypohepatia, 2 sicca syndrome, and 2 anemia. ResultsAll the patients were stable peri-operatively. No patient had adrenal crisis. Four complications were noted, including one case of fever reaction (maximum temperature:39.3℃), 1 incision fat liquefaction, 1 pulmonary infection, and 1 early dislocation due to improper exercise on the 12th day after the operation. The patients were followed up for 24 to 53 months, and there was no deep infection, prosthetic loosening, peri-prosthetic fracture or deep vein thrombosis after THA. ConclusionAlthough the incidence of postoperative complication is high in patients with SLE and ANFH undergoing THA, meticulous perioperative management can help these patients get through operation safely, including the use of glucocorticoid and antibiotics, treatment of osteoporosis, and prevention and treatment of complications.
