RESUMO
Objective: To identify the correlation between pre-treatment per ipheral blood platelet-l ymphoc y te rat io (PLR) and the clinicopathological features of the patients with peripheral T cell lymphoma, unspecified (PTCL-U), and to explore the prognostic significance of PLR in these patients. Methods: The clinical characteristics and survival state of 163 patients diagnosed of PTCL-U in Tianjin Medical University Cancer Institute and Hospital were analyzed retrospectively. All patients were divided into low PLR group (PLR < 170, n = 80) and high PLR group (PLR ≥ 170, n = 83) based on the receiver operating characteristic (ROC) curve's cut-off value. The relationship between pre-treatment PLR and the prognosis of these patients was analyzed. Results: In all 163 patients with PTCL-U, the 5-year overall sarvival (OS) and progression-free survival (PFS) rates of patients in low PLR group (76.3% and 60.0%, respectively) were higher than those in high PLR group (10.8% and 8.4%, respectively, both P < 0.05). Age, Eastern Cooperative Oncology Group performance status (ECOG PS), B symptoms, serum lactate dehydrogenase (LDH) level, platelet and PLR were remarkably relevant to OS (all P < 0.01). Age, serum LDH level, platelet and PLR were independent prognostic features for patients with PTCL-U (all P < 0.05). Conclusion: The peripheral blood PLR at pre-treatment is distinctly relevant to the prognosis of patients with PTCL-U. An elevated PLR predicts poor prognosis of these patients.
RESUMO
Background and purpose: Natural killer/T-cell lymphoma (NKTCL) is a scarce subtype of malignant lymphoma, and it has heterogeneous clinical manifestation and treatment effect. Currently, no precise risk stratification is used to guide prognosis. This study aimed to evaluate the prognostic impact of pre-treatment peripheral blood absolute monocyte count (AMC) and platelet-lymphocyte ratio (PLR) in patients with primary nasal NKTCL, and provide more precise information for better risk stratification to select appropriate treatment and improve survival. Methods: Clinical data of 132 patients newly diagnosed with primary nasal NKTCL was collected in the Tianjin Medical University Cancer Institute and Hospital from Jan. 2008 to Dec. 2013. The relationship between AMC and PLR in pre-treatment peripheral blood and 5-year overall survival (OS) and progression-free survival (PFS) of patients was analyzed retrospectively. Independent prognostic factors of patients were determined by univariate analysis and Cox regression analysis. Results: Pre-treatment peripheral blood AMC and PLR play important roles in the prognosis stratification of patients with primary nasal NKTCL. The prognosis in patients of AMC<0.5×109/L were higher than those of AMC≥0.5×109/L, The prognosis in patients of PLR<150 were higher than those of PLR≥150 (P<0.05). Based on the four independent risk factors of staging, ECOG scoring, AMC and PLR, we tried to establish a new prognostic model, dividing all patients into three different risk groups and found that the 5-year OS and PFS of three groups had significant statistical differences. Conclusion: Peripheral blood AMC and PLR were significantly correlated with the prognosis of patients with primary nasal NKTCL. The new prognostic patterns based on the four independent risk factors, such as staging, ECOG scoring, AMC and PLR may be more convenient and more economical than IPI (International Prognostic Index, IPI) and KPI (Korean Prognostic Index, KPI).
RESUMO
One hundred and seventy six consecutive patients with acute ischemic stroke who received intravenous recombinant tissue plasminogen activator ( rt-PA ) in 4.5 hours from symptom onset during February 2009 to July 2013 were included in the study.Modified Rankin Scale was used to evaluate the recovery of neurological functions.Patients were divided into good ( 0 -1 ) or poor ( 2 -6 ) outcome groups according modified Rankin Scale score.Univariate analysis and multivariate logistic regression analysis were used to determine the differences of clinical data between the two groups.The age of patients with good outcome was significantly lower than that of poor outcome group [ ( 61.4 ±11.5 ) vs.( 69.0 ± 13.2) years,P =0.000].Compared to patients with poor outcomes, patients with good outcome group showed lower rate of diabetes [ 13%( 12/93 ) vs.29%( 24/83 ) , P =0.009 ] , lower blood glucose level [(5.05 ±0.97) vs.(5.83 ±1.72) mmol/L,P=0.020], higher uric acid level[(404.4 ±151.7) vs.(345.6 ±107.5) μmol/L,P=0.028],shorter onset to treatment time [(1.92 ±0.94) vs.(2.30 ±1.01) h, P=0.019],lower baseline National Institute of Health Stroke Scale score [(14.0 ±5.2) vs.(16.0 ± 6.2),P=0.025],lower systolic blood pressure level at 2 h[(140.8 ±18.3) vs.(149.0 ±18.9) mmHg (1 mmHg=0.133 kPa),P=0.005]and 24 h [(137.6 ±21.9) vs.(147.1 ±17.4) mmHg,P=0.009] after thrombolysis.Logistic regression analysis showed that uric acid levels were not related to hemorrhagic transformation independently (P =0.172,OR =0.965,95%CI:0.917 -1.016), but were related to outcome independently (P=0.047,OR=0.957,95%CI:0.916-0.999).
RESUMO
OBJECTIVE: To containment the unhealthy tendency in drug purchase and to promote the healthy and harmonious development of heath service.METHODS: Honest government risk prevention & control pattern was established in our hospital,and the system construction was strengthened,furthermore,a scientific operation flow was formulated,and a system of rewards and disciplinary evaluation was established.RESULTS: With the honest government risk prevention & control pattern,the centralized public bidding was achieved in 100% of the hospital drug purchasing,the clinical drug use tends to be more and more rational and standard,and the drug use structure became more reasonable,the honest government risk in drug purchase and sale has been effectively avoided.CONCLUSION: This honest government risk prevention & control pattern is practical and feasible thus deserving popularized in medical institutions.
