Objective:To evaluate the prognostic value of Karnofsky performance scores (KPS) in elderly patients with sepsis, so as provide a basis for clinical evaluation of the condition, prognosis and corresponding treatment measures.Methods:A retrospective cohort study was conducted to collect the general information, clinical data, and follow-up data of limb motor function status and self-care ability of elderly patients with sepsis who were hospitalized in the Intensive Care Unit of our hospital from January 2018 to June 2021. Patients were divided into the survival group and death group according to whether they survived the hospitalization. Statistical analysis was performed using t-test, chi-square test, and Mann-Whitney test. The KPS score before admission, disease severity scores (APACHEⅡ and SOFA), serum procalcitonin (PCT), N-terminal pro-brain natriuretic peptide (NT-proBNP), and arterial blood lactate level on admission were compared between the two groups. Then, the factors with significance in univariate analysis were analyzed by Logistic regression method, the independent risk factors for predicting in-hospital mortality were determined, and the receiver operating characteristic (ROC) curve was drawn to evaluate the prognostic value of KPS score in elderly patients with sepsis.Results:A total of 135 patients were collected. There were 85 males and 50 females, 60 died and 75 survived during hospitalization, with a mortality rate of 44.4%. The preadmission KPS score of elderly patients with sepsis in the death group was significantly lower than that in the survival group [30 (30, 40) vs. 70 (50, 90), P<0.001]. Multivariate logistic regression analysis showed that KPS score ( OR=0.938, 95% CI: 0.914-0.963, P<0.001), SOFA score ( OR=1.255, 95% CI: 1.066-1.451, P=0.002) and arterial blood lactate ( OR=1.219, 95% CI: 1.059-1.404, P=0.006) were independent risk factors for predicting the prognosis during hospitalization. ROC curve analysis of mortality showed that compared with SOFA score and blood lactate, the area under the curve of KPS score was the largest, with AUC of 0.830 (95% CI: 0.756-0.890, P<0.001). In addition, the combination of KPS, SOFA and blood lactate had a greater predictive value for the prognosis of elderly patients with sepsis than that of the single index, with an AUC of 0.883 (95% CI: 0.826-0.940, P<0.001). Conclusions:The lower the KPS score, the worse the prognosis of elderly patients with sepsis. The KPS score can be used as a clinical indicator to predict the prognosis of elderly patients with sepsis.

AIM:To investigate the mutation of FLT3-ITD gene in the patients with newly diagnosed acute myeloid leukemia (AML). METHODS:From March 1, 2015 to June 1, 2017, 207 patients with AML admitted to de-partment of hematology, sichuan provincial people′s hospital were enrolled in this study. The bone marrow samples were collected from the patients. PCR was used to detect the mutation of FLT3-ITD gene. After the corresponding chromosome was obtained by R-banding, the cells were made into strips and banding. Twenty karyotypes with relatively cleavage were automatically selected from each specimen to complete karyotyping. By analysis of the clinical data and following-up the prognosis, the FLT3-ITD gene mutation in diagnostic and evaluative values for AML were performed. RESULTS:FLT3-ITD gene mutation was found in 42 cases of 207 AML patients, the positive rate was 20. 29 % . FLT3-ITD positive patients showed 3 bands. FLT3-ITD gene mutation in 42 patients with positive results showed that FLT3-ITD gene mutations in turn met the end to end, and insert a number of nucleotides, but all the mutations were in-frame mutations. According to the FAB and WHO standard, in 42 cases of FLT3-ITD positive positive patients, M0 accounted for 0.00% , M1 accounted for 2.38% (1/42), M2 accounted for 23.81% (10/42), M3 accounted for 0.00% , M4 accounted for 2.38% (1/42), M5 accounted for 69.05% (29/42), M6 accounted for 0.00% , M7 accounted for 2.38% (1/42). The white blood cell ( WBC) level and complete response (CR) rate in FLT3-ITD positive patients were lower than those in FLT3-ITD negative patients (P<0.05). CONCLUSION:The WBC level and CR rate, which are lower in FLT3-ITD positive patients than those in negative patients, are the clinical risk factors. It will be helpful to determine the prognosis evaluation for AML pa-tients.

Objective:To investigate the function of breast cancer susceptibility gene variants in predicting breast cancer risk and guid-ing clinical treatment through DNA sequencing. Methods:This study involved 146 patients, 71 high-risk cases, and 55 healthy people, totaling 272 cases. The subjects were treated in Tianjin Medical University Cancer Institute and Hospital from November 2013 to July 2015. Genomic DNA was sequenced by a second generation sequencing platform. All exon areas of six common breast cancer suscepti-bility genes (BRCA1, BRCA2, PTEN, STK11, TP53, and RAP1) were sequenced through amplicon sequencing method. Meaningful vari-ants including single nucleotide variants (SNVs), insertion-deletions (InDels) and nonsense mutations were selected and statistical methods, such as t test andχ2 test, were used to analyze the statistical differences in incidence rates among three groups. Results:A total of 177 meaningful variants were confirmed, including 50 SNVs, 8 nonsense mutations, and 9 InDels. Among the variants, 31 were recorded in the Exome Aggregation Consortium (ExAC), 40 were noted in ClinVar database, and 21 were not encoded in the present da-tabase, which were defined as new variants in this study. Conversely, 57 variants (85.1%) were found in breast cancer patients and high-risk cases, and the incidence of axillary lymph node metastasis (P=0.010) and pathological stages (P=0.002) in mutation positive patients were both higher than mutation negative patients. Moreover, the percentage of family history of cancer (P=0.005) and triple negative breast cancer (P=0.009) were both higher in patients carrying pathogenic mutations than in nonpathogenic patients. Conclu-sion:Breast cancer susceptibility gene variants may not only be a tool used to predict the risk of getting breast cancer but also a mean-ingful guideline for the clinical treatment and prognosis evaluation.

ObjectiveTo estimate the value of serum soluble scavenger receptor CD163 (sCD163) to the prognosis of patients with stroke associated pneumonia (SAP).Methods A prospective study was conducted. The clinically suspected SAP patients admitted to Department of Intensive Care Unit (ICU) and Emergency ICU (EICU) in Zhejiang Province Zhuji City Chinese Medicine Hospital from February 2014 to January 2015 were all enrolled. According to clinical pneumonia severity index (PSI), they were divided into SAP group and non SAP group according to the presence or absence of SAP, the patients of SAP group were subdivided into mild SAP group (PSI grade Ⅰ-Ⅲgrade) and severe SAP groups (PSI grade Ⅳ-Ⅴ grade) and according to the 28-day prognosis, the patients were subdivided into hospitalized death group and survival group. The clinical data were collected, including gender, age, history of stroke presence or absence, present stroke pattern, National Institutes of Health Stroke Scale score (NIHSS) on the day of stroke suspect diagnosis, Glasgow coma scale (GCS) score, acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ) score, clinical pulmonary infection score (CPIS), PSI score, body temperature, result of chest X-ray film, oxygenation index (PaO2/FiO2), result of sputum culture, serum levels of white blood cell (WBC) and C-reactive protein (CRP) in a period of 7 days after the suspected diagnosis, PCT, sCDl63 levels on days 1, 3, 5, 7 days, length of stay in ICU, the total time of hospitalization and 28-day survival situation, etc. The ability of each index to evaluate the prognosis of SAP was analyzed by the receiver operating characteristic curve (ROC curve). The risk factors influencing the prognosis of SAP patients were analyzed by multivariate logistic regression analysis.Results ① Seventy-eight patients were finally enrolled in the study, 44 patients were diagnosed as SAP, 34 were non SAP. In 44 patients with SAP, there were 28 cases of severe SAP and 16 cases of mild SAP. On the first day of the suspected diagnosis, the NIHSS score [13 (7, 22) vs. 8 (4, 17), the CPIS score [6 (4, 9) vs. 4 (3, 5), sCD163 [mg/L: 0.80 (0.59, 1.32) vs. 0.33 (0.22, 0.46)], CRP [mg/L: 84.2 (50.8, 114.9) vs. 51.4 (26.2, 79.9)] and 28-day mortality [38.6% (17/44) vs. 11.8% (4/34)] in SAP group were significantly higher than those in non SAP group (allP 0.05). ② The levels of sCD163 reached the peak value on the third day after the suspected diagnosis among SAP group and non SAP group, mild SAP group and severe SAP group, survival group and death group and then began to fall; the levels of sCD163, WBC, CRP, PCT within 7 days in SAP, severe SAP and death groups were higher than those in non SAP, mild SAP and survival groups (allP < 0.05). ③ROC curve analysis indicated: sCDl63 showed a better capacity for evaluating the 28-day prognosis of SAP [ROC curve (AUC) =0.673, 95% confidence interval (95%CI) = 0.515-0.807, sensitivity and specificity were 41.2% and 96.3% respectively and the cut-off was 2.65 mg/L]. However, the levels of other inflammatory indexes and scores on the first day after the suspected diagnosis had no value for early prognosis of SAP. The multiple logistic regression analysis showed that the level of sCD163 on the first day after the suspected diagnosis was the independent risk factor of death in hospital of SAP patients [dominance ratio (OR = 1.27, 95%CI = 1.06-1.52,P < 0.05]. Age (OR = 1.04, 95%CI = 1.01-1.06,P = 0.015), NIHSS score (OR = 2.86, 95%CI = 1.64-4.92,P = 0.010), CPIS score (OR = 1.52,95%CI = 1.28-1.90,P < 0.001) and APACHEⅡ score (OR = 2.06, 95%CI = 1.53-3.07,P < 0.001) were also the risk factors of influencing the death of patients with SAP.Conclusions Early sCD163 level is an independent risk factor in predicting the 28-day mortality of patients with SAP, and it has a certain value for the prognosis of SAP.
