Research advances of preoperative clinical prognostic factors for recurrent hepatocellular carcinoma after liver transplantation / 中华器官移植杂志

Liver transplantation (LT) is an important treatment of unresectable hepatocellular carcinoma (HCC). However, the prognosis of tumor recurrence remains poor.If patients with a high risk of tumor recurrence after LT can be predicted preoperatively, suitable recipients are screened so that individualized monitoring and treatment protocols may be formulated for high-risk patients.Then better outcomes are obtained.Therefore it is imperative to accurately identify the relevant risk factors and select appropriate parameters for evaluate the risks of tumor recurrence before LT.This review summarized the latest researches of preoperative clinical predictors for recurrent HCC after LT.It was intended to provide references for selecting recipients and a proper management of high-risk patients.

A simple and successful treatment for rupture and defect of the posterior third superior sagittal sinus caused by open depressed skull fracture: A case report / 中华创伤杂志(英文版)

It is extremely dangerous to treat the posterior third of the superior sagittal sinus (PTSSS) surgically, since it is usually not completely ligated. In this report, the authors described the case of a 27-year-old man with a ruptured and defective PTSSS caused by an open depressed skull fracture, which was treated by ligation of the PTSSS and the patient achieved a positive recovery. The patient's occiput was hit by a height-limiting rod and was in a mild coma. A CT scan showed an open depressed skull fracture overlying the PTSSS and a diffuse brain swelling. He underwent emergency surgery. When the skull fragments were removed, a 4 cm segment of the superior sagittal sinus (SSS) and the adjacent dura mater were removed together with bone fragments. Haemorrhage occurred and blood pressure dropped. We completed the operation by ligating the severed ends of the fractured sagittal sinus. One month after the operation, apart from visual field defects, he recovered well. In our opinion, in primary hospitals, when patients with severely injured PTSSS cannot sustain a long-time and complicated operation, e.g., the bypass using venous graft, and face life-threatening conditions, ligation of the PTSSS is another option, which may unexpectedly achieve good results.

Research Progress of Genes Related to Treatment and Prognosis of Alpha-fetoprotein Producing Gastric Cancer / 肿瘤防治研究

Alpha-fetoprotein producing gastric cancer (AFPGC) is a special type of gastric cancer. AFPGC is considered to be the most highly invasive tumor with a high degree of malignancy and prone to metastasis. As a consequence, it usually causes unsatisfied treatment effect and the prognosis is poor. At present, treatment methods and monitoring indicators have limited effect on AFPGC. VEGF, HER2, AFP, GPC3 and SALL4 are cogently associated with tumor genesis and development. If we can reasonably guide the treatment and prognosis of AFPGC patients, it will greatly improve the situation of patients and improve the survival of patients. This article reviews the research progress of the genes related to the treatment and prognosis of AFPGC.

Analysis and evaluation of risk factors associated with poor prognoses of children with tetralogy of Fallot during perioperative period / 中国胸心血管外科临床杂志

@#Objective    To quest the risk factors of poor prognoses in children with tetralogy of Fallot (TOF) during perioperative period and evaluate its clinical application values. Methods    A retrospective analysis of the clinical data of 119 children who underwent one-stage correction of TOF in Guangdong Provincial People's Hospital from September 2016 to January 2019. The cohort includes 75 males and 44 females, with ages ranging from 3.2-137.1 (13.2±1.4) months and weights ranging from 4.6-21.0 (8.3±0.2) kg. Perioperative poor prognosis was defined as duration of mechanically assisted ventilation >48 h or secondary intubation, vasoactive-inotropic score (VIS) within 48 h >40, postoperative length of stay >14 d, and the occurrence of the major adverse events. Major adverse events were defined as early death, malignant arrhythmia, low cardiac output syndrome, non-fatal cardiac arrest, postoperative reintervention, diaphragm paralysis, and other clinical complications. Univariate and multivariate logistic analyses were used to analyze the correlation between risk factors and poor prognoses. Results    There was 1 perioperative death, and 9 with major adverse events. Variables selected by Least Absolute Shrinkage and Selection Operator (LASSO) included 2 preoperative variables (McGoon index, aortic root diameter index) and 4 intra-operative variables [left-right direction of bicuspid pulmonary valve, total length of right ventricular outflow tract (RVOT) incision index, pulmonary valve with commissurotomy, and minimum temperature in cardiopulmonary bypass (CPB)]. Univariate and multivariate logistic analyses were used to the above factors, respectively. The variables with statistical significance (P≤0.05) were McGoon index, aortic root diameter index, left-right direction of bicuspid pulmonary valve, and minimum temperature in CPB. A nomogram was established based on the above factors, and the results showed that the left-right direction of bicuspid pulmonary valve was more risky than the tricuspid pulmonary valve and the anterior-posterior direction of bicuspid pulmonary valve. The lower the McGoon index, the higher aortic root diameter, and the lower temperature in CPB, the higher risk of poor prognostic events in children with TOF. Conclusion    The left-right direction of the pulmonary bicuspid valve has a higher risk of poor prognosis than the tricuspid pulmonary valve and the anterior-posterior direction of bicuspid pulmonary valve. With the smaller McGoon index and the larger aortic root diameter, the risk of poor prognoses in children with TOF is higher. The temperature in CPB being lower than medium-low temperature obviously relates to the high incidence of poor prognostic events, which can be used as an auxiliary reference standard for decision-making in pediatric TOF surgery in the future.

A Centralized Report on Pediatric Japanese Encephalitis Cases from Beijing Children's Hospital, 2013 / 生物医学与环境科学（英文）

Fifteen pediatric cases of suspected Japanese encephalitis (JE) were reported in Beijing Children's Hospital during the late summer of 2013. The clinical manifestations in most cases included high fever, seizures, and abnormal magnetic resonance imaging findings. Twelve of 15 cases were laboratory-confirmed as JE cases by pathogen identification. Epidemiological investigations showed that five of the 12 laboratory-confirmed patients had an incomplete JE vaccination history. Follow-up investigations after discharge indicated that seven laboratory-confirmed JE patients without JE vaccinations had relatively poor prognoses, with an average Modified Rankin Scale (MRS) score of 2.6 when compared with the other five laboratory-confirmed, JE-vaccinated patients with an average MRS score of 0.5. The observation of pediatric JE cases among those with a history of JE vaccination warrants further attention.

The clinical characteristics and prognosis of de novo acute myeloid leukemia patients with CCAAT/enhancer binding protein α mutations / 白血病·淋巴瘤

Objective To explore the clinical characteristics and prognosis of acute myeloid leukemia (AML) patients with CCAAT/enhancer binding protein α (CEBPA) mutations.Methods 208 patients with de novo AML were retrospectively analyzed with regard to frequency of CEBPA mutations,clinical characteristics,therapeutic response and long-term outcome.Results CEBPA mutations were detected in 37 patients (17.8 ％),with 29 cases of double mutations and 8 cases of single mutation.In 117 cases of patients with normal karyotype,28 cases (23.9 ％) were detected with CEBPA mutations.As compared with no CEBPA mutation,the following characteristics were observed in patients with CEBPA double mutations.Presented with younger age at diagnosis,82.8 ％ (24/29) of the patients were M1 and M2.Presented with higher peripheral white blood cell count,higher hemoglob in and low platelet count.And increases of CD7,CD34 and HLA-DR expression.Compared with those without mutation,patients with biCEBPA mutations had better overall survival (OS) (2-years OS:100 ％ vs 75.1％,P =0.045).Conclusion BiCEBPA mutation is one of the favorable prognosis indicators.

Patients with both hepatocellular and chnlangiocarcinoma and their clinicopathological features / 中华肝胆外科杂志

Combined hepatocellular and cholangiocarcinoma (HCC-CC) is a unique primary epithelial tumor of the liver classified by the WorldHealth Organization (WHO) as a tumor containing elements of both hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC).The clinical diagnosis is established by histopathology and a firm pathological diagnosis from definitive evidence of HCC and CC differentiation.HCC-CC's clinical features tend to resemble hepatocellular carcinoma in regards to venous infiltration and like cholangiocarcinoma with respect to lymph node metastasis.To date,the biological behavior of HCC-CC remains ill-defined; however its prognosis seems to be worse than just HCC.Conversely,it is unclear whether the prognosis of HCC-CC is better than that of only ICC.This paper reviews recent studies on the clinicopathological behavior of HCC-CC.

Mortalidad por influenza y neumonía. Tendencia, estacionalidad y pronósticos. Jagüey Grande, 2002-2010 / Mortality caused by influenza and pneumonia. Tendency, seasonality and prognosis. Jagüey Grande, 2002-2010

La influenza y la neumonía constituyen una de las primeras causas de morbimortalidad en el mundo. En Cuba, son la cuarta causa de muerte; pero la magnitud de este problema de salud es mucho mayor al quedar también oculta tras otras causas de muerte y no ser registrada en las estadísticas vitales. Es importante conocer su magnitud, tendencia, características de comportamiento y pronóstico para su vigilancia e inclusión al evaluar acciones de prevención y control. Se realizó una investigación descriptiva de series temporales de la mortalidad por influenza y neumonía como causa básica, causa oculta y ambas incluidas, que se denominó “mortalidad total”. Se revisaron los certificados médicos de defunción de los 3 433 fallecidos residentes en el municipio de Jagüey Grande, en el período 2002-2010. En 1 127 de ellos, se registró la influenza y la neumonía como eventos mórbidos que intervinieron en su muerte, y en 323, se registró en las estadísticas vitales como causa básica. Se conformaron tres series de tiempo, de las que se analizaron su magnitud y tendencia. De la mortalidad total se describe su variabilidad mensual, estacionalidad y se pronostica el comportamiento esperado para el año 2011. Se utilizan técnicas recomendadas para el análisis de series temporales, incluyendo la modelación ARIMA para los pronósticos. La tendencia de mortalidad por influenza y neumonía como causa básica es descendente, mientras que la causa oculta y la causa total ascienden. No se encontró comportamiento estacional manifiesto de la serie de mortalidad total. Además, se hacen pronósticos mensuales para el año 2011.

The influenza and the pneumonia are one of the first causes of morbimortality around the world. In Cuba , they are the fourth cause of death; but the magnitude of the health problem is bigger because it is hidden behind other death causes and is not registered in the statistics. It is important to know its magnitude, tendency, behavioral characteristics and prognosis for the surveillance and inclusion when evaluating actions for prevention and control. We carried out a descriptive research of temporal mortality series for influenza and pneumonia as basic causes, hidden cause or both, called -total mortality-. We reviewed the decease medical certificates of the 3 433 deceased persons who lived in Jagüey Grande, in the period 2002-2010. In 1 127 of them, the influenza and the pneumonia are registered as morbid events that got involved in the decease, and in 323, they were registered as the main causes of death. We formed three time series, analyzing the magnitude and tendency. The total mortality is described as a monthly variability, seasonal, and we predict the behavior for 2011. We use the techniques recommended for the analysis of temporal series, including the ARIMA model for the prognoses. The mortality tendency by influenza and pneumonia as basic cause is descendent, while as hidden cause and as total cause is increasing. We did not find an open seasonal behavior of the total mortality series. We also make monthly prognoses for 2011 .

Rhinosinusitis in autologous and allogeneic bone marrow transplantation: a retrospective study on the performance of imaging studies on severity and prognostic evaluation / Rinossinusite em transplante de células-tronco hematopoéticas autólogo e alogênico: um estudo retrospectivo sobre o desempenho de estudos de imagem na avaliação de severidade e prognóstico

The objective of this work was to evaluate the diagnostic and prognostic performance of a traditional imaging staging system for rhinosinusitis in the bone marrow transplantation (BMT) scenario. A retrospective cohort study was carried out at a bone marrow transplantation referral center involving subjects who underwent allogeneic or autologous BMT from September 1st 2005 to September 31st 2007 and later evolved with rhinosinusitis during the BMT inpatient period. Patients who had a previous history of sinusal disease or otolaryngologic surgery were excluded from the study. Data concerning mortality, the treatment of rhinosinusitis and BMT outcomes were extracted from medical files. The collected parameters were compared to the Lund-Mackay tomographic staging system score which was calculated based on available tomography films of each patient. A total of 85 BMT were performed and 23 allogeneic and 14 autologous (43.5 percent) BMT patients evolved with rhinosinusitis during transplantation. A significant association with LMS was found for the absolute neutrophil count (ANC), with a higher ANC (>500/mm3) correlating with a higher LMS (Mean LMS for lower ANC 6.08 and higher ANC 9.71 points, p<0.05). Need for surgical management and post-BMT admissions, the resolution of the rhinosinusitis and overall mortality had no significant correlation with LMS. Patients with less than 500 neutrophils/mm3 are known to be prone to more severe infections, but paradoxically showed lower LMS when developing rhinosinusitis. However, there were no differences in the main outcomes between those with higher and lower LMS. This would possibly lead to an equivocal assumption of a less severe disease. Severely neutropenic patients are probably not able to mount an effective inflammatory response capable of inducing significant tomographic abnormalities. So, this imaging study would not be able to adequately evaluate the extent of sinusal involvement. We thus ...

O objetivo deste trabalho foi avaliar o desempenho diagnóstico e prognóstico de um escore de estadiamento de rinossinusite (RS) por tomografia em pacientes submetidos a transplante de medula óssea (TMO). Realizou-se um estudo de coorte retrospectivo de pacientes submetidos a transplante de medula óssea (autólogo e alogênico) de 1º de setembro de 2005 a 31 de setembro de 2007 que desenvolveram RS durante o período de internação do transplante. Pacientes com história prévia de doença sinusal ou cirurgia otorrinolaringológica foram excluídos do estudo. Dados relacionados à mortalidade, resolução da RS e desfechos do TMO foram extraídos do prontuário médico. Os parâmetros coletados foram correlacionados com o escore de estadiamento de Lund-Mackay (ELM), que foi calculado com base nas alterações tomográficas de cada paciente. Um total de 85 TMO foram realizados e 37 (23 alogênicos e 14 autólogos) destes pacientes desenvolveram RS durante o transplante. Uma correlação significativa com o ELM foi encontrada quando se considerava a contagem absoluta de neutrófilos (CAN), com uma CAN mais alta (>500/mcl) se associando com um ELM de maior valor (média de escore para CAN baixa 6,08 e CAN alta 9,71 pontos, p<0,05). A necessidade de intervenção cirúrgica e reinternações pós-TMO, resolução da RS e mortalidade geral não mostraram correlação com o ELM. Mesmo assumindo que a neutropenia severa é um fator de risco relevante para intercorrências infecciosas durante o TMO, paradoxalmente, os pacientes com menos de 500 neutrófilos/mcl mostraram um ELM de menor severidade, embora não tenham evoluído de maneira diferente daqueles com maior ELM. É provável que ELM mais alto esteja simplesmente ligado ao fato de uma CAN mais alta levar a uma maior reação inflamatória e consequente alteração tomográfica. Desta forma, o ELM não parece útil na avaliação de pacientes altamente imunossuprimidos como os do TMO. Rev. Bras. Hematol. Hemoter.

Sistema Glutation-S-Transferase como fator prognóstico no carcinoma papilífero da tireoide / GST genes expression as prognostic factor in papillary thyroid cancer

OBJETIVO: Analisar se existe relação entre os fatores moleculares dos genes GTS e a mortalidade dos pacientes com câncer de tireoide dado pelo índice AMES de prognóstico clínico. MÉTODOS: Foram coletadas amostras da tireoide de 66 pacientes com carcinoma papilífero (53 mulheres e 13 homens), de modo a permitir extração do material genético das enzimas. Foram constituídos dois grupos, segundo os fatores prognósticos clínicos de alto e baixo risco, de acordo a classificação AMES. Cada grupo foi avaliado pela presença ou não do genótipo nulo para as enzimas estudadas, correlacionando-os com os fatores prognósticos clínicos (AMES). RESULTADOS: Foram analisados os resultados de 17 doentes com alto risco (grupo A) e 49 com baixo (grupo B). Todas combinações de genótipos do GSTT1 e GSTM1 foram encontrados. O genótipo nulo dos dois genes do grupo de alto risco foi encontrado em 5,8 por cento e no de baixo risco em 6,1 por cento. CONCLUSÃO: A presença ou deleção dos genes GST (GSTT1 e GSTM1) não são bom fatores prognósticos no câncer papilífero da tireoide.

PURPOSES: Analyze the relationship between the AMES classification and molecular factors from Glutation-S-Transferase System, specifically the GSTT1 and GSTM1 in patients with well differentiated thyroid cancer. METHODS: Samples of thyroid tissue of 66 patients with papillary thyroid carcinoma were obtained (53 women and 13 men). Patients were divided in two groups (high and low risk) according to the AMES classification. In each group, presence of the null genotype of both GST enzymes system was studied. These results were compared with the AMES classification. Samples were obtained in the operating room immediately after thyroidectomy, placed in cryotubes, immersed in liquid nitrogen and stored in a freezer at -80ºC. DNA of this enzymes was extracted by the fenol-cloroformium method. RESULTS: There were 17 high risk patients and 49 low risk patients. The null genotype of the high risk group was 5.8 percent and in the other group was 6.1 percent. CONCLUSION: There was no relationship between absence of genes GSTT1 and GSTM1 and prognosis of the papillary thyroid carcinoma when compared to the AMES classifications.

The prognosis of patients with stage Ⅰb-Ⅱb node-negative cervical carcinoma / 中国癌症杂志

Purpose:To investigate the survival and prognostic factors in patients with stage Ib～IIb node-negative cervical carcinoma.Methods:From Nov.1993 to Dec. 1997,236 patients who had radical hysterectomy and pelvic lymphadenectomy and pelvic lymph node found negative were reviewed retrospectively. Survival rates were calculated by Kaplan-Meier method with differences in survival estimated by Log-rank test. Independent prognostic factors were identified by the Cox's proportional-hazards regression model. Results:The overall 5-year survival of the patients was 82.0% and the median survival time was 100.0 months. The recurrence and/or metastatic rate was 19.5%. Of these patients the 5-year survival rate was 16.9% and median survival time was 15.0 months. Among the variables,clinical stage(Ⅱb),tumor size(≥4 cm),histological type (non-squamous carcinoma),poor differentiation,deep stromal invasion,parametrial extension,vaginal margin involved,and lymphvascular permeation were the poor prognostic factors in univariate survival analysis ( P
