METHODS: After the diagnosis of HCC, all 995 consecutive HCC patients were followed up at regular intervals and 151 (15.2%) patients were found to have extrahepatic metastases at the initial diagnosis of primary HCC or developed such tumors during the follow-up period. We assessed their clinical features, prognosis, and treatment strategies. RESULTS: The most frequent site of extrahepatic metastases was the lungs (47%), followed by lymph nodes (45%), bones (37%), and adrenal glands (12%). The cumulative survival rates after the initial diagnosis of extrahepatic metastases at 6, 12, 24, and 36 mo were 44.1%, 21.7%, 14.2%, 7.1%, respectively. The median survival time was 4.9 mo (range, 0-37 mo). Fourteen patients (11%) died of extrahepatic HCC, others died of primary HCC or liver failure. CONCLUSION: The prognosis of HCC patients with extrahepatic metastases is poor. With regard to the cause of death, many patients would die of intrahepatic HCC and few of extrahepatic metastases. Although most of HCC patients with extrahepatic metastases should undergo treatment for the primary HCC mainly, treatment of extrahepatic metastases in selected HCC patients who have good hepatic reserve, intrahepatictumor stage (T0-T2), and are free of portal venous invasion may improve survival.展开更多

This study correlated neuro- nal injury in the cerebral cortex of 16 patients with chronic stroke based on a voxel-based lesion symptom mapping analysis. Neuronal injury in the corona radiata, caudate nucleus and putamen of patients with chronic stroke could predict walking speed. The behavioral measure scores were consistent with motor deficits expected after damage to the cortical motor system due to stroke. These findings suggest that voxel-based lesion symptom mapping may provide a more accurate prognosis of motor recovery from chronic stroke according to neuronal injury in cerebral motor cortex.展开更多

[Method] Field investigation and comprehensive analysis of the literature were conducted to study the reason of dry straight head disease in Chuzhou area, some common control measures were summarized. [Result] The characteristic of main symptoms included incidence of single plant, incidence of cluster, inclusive incidence between clusters. Sporadic normal rice grains existed in diseased spikes under the incidence of grains. The main pathogenic factors of dry straight head disease were concentration of arsenic or lack of elements, belonging to physiological disease, while the effect of other pathogenic factors could not be excluded. Heavy application of organic fertilizer and crop rotation should be conducted, white soil field should be paid more attention about the changes of disease condition with more wet and dry roasting over fields. Application time of micro fertilizer should be chosen properly, while tillering final stage and pollen formation stage must be adjusted to avoid high temperature, irrigation management should also be improved.

A growing number of studies have reported gastrointestinal (GI) symptoms. The study aimed to estimate the various digestive symptoms frequently reported in Covid-19 patients among the adult population of Bangladesh. Methods: In this descriptive, cross-sectional study, we enrolled confirmed patients with COVID-19 who were admitted to the COVID unit of Shaheed Suhrawardy Medical college hospital, Dhaka from July 2020 to December 2020. All patients were COVID confirmed by real-time polymerase chain reaction (RT-PCR) and were analyzed for clinical characteristics, laboratory findings and imaging study. Results: The study population consisted of 121 COVID-19-positive patients, among them, 57.85% were male and 42.15% female. The majority (43%) of the study population were in the age group of 31 - 40 years. The male to female ratio was 1.4:1. Nearly 94.2% of the sample population were married, among them 92.9% were male and 96.1% were female. Out of 121 Covid-19 patients, 30.65% had a contact history, 17.4% had a history of traveling or residing in an area reporting COVID-19 and 11.6% of family members were affected by Covid-19. Most of the patients had a fever (95%), cough (88.4%) and dyspnoea (43.8%), pneumonia (37.4%) and severe pneumonia (36.4%). In this study, 40% patients reported a digestive symptom including diarrhea 47.9%, vomiting 55.5%, loss of appetite 16.5%, abdominal pain 29.8%, abdominal bloating 24.8%, reflux 0%, jaundice 3.3%. Regarding co-morbidities, the majority had bronchial asthma (50%) followed by hypertension 46%, diabetes 38%, obesity 23%, and CKD 14% and heart disease 3%. Among 121 COVID-19 patients, 98% had recovered from the disease and 2% of patients expired. Conclusion: Gastrointestinal symptoms are common among patients with COVID-19 and this group of patients had a long time of hospital stay from onset to admission, and higher liver enzyme levels. During the management of COVID-19 patients, clinicians need to be alert regarding suspicion of the GI features among COVID-19, so that they can diagnose early and treat effectively and immediately.展开更多

文摘Leukoaraiosis(LA)results from ischemic injury in small cerebral vessels,which may be attributable to decreased vascular density,reduced cerebrovascular angiogenesis,decreased cerebral blood flow,or microcirculatory dysfunction in the brain.In this study,we enrolled 357 patients with mild intracerebral hemorrhage(ICH)from five hospitals in China and analyzed the relationships between LA and clinical symptom severity at admission,neurological function prognosis at 3 months,and 1-year stroke recurrence.Patients were divided into groups based on Fazekas scale scores:no LA(n=83),mild LA(n=64),moderate LA(n=98)and severe LA(n=112).More severe LA,larger hematoma volume,and higher blood glucose level at admission were associated with more severe neurological deficit.More severe LA,older age and larger hematoma volume were associated with worse neurological function prognosis at 3 months.In addition,moderate-to-severe LA,admission glucose and symptom-free cerebral infarction were associated with 1-year stroke recurrence.These findings suggest that LA severity may be a potential marker of individual ICH vulnerability,which can be characterized by poor tolerance to intracerebral attack or poor recovery ability after ICH.Evaluating LA severity in patients with mild ICH may help neurologists to optimize treatment protocols.This study was approved by the Ethics Committee of Ruijin Hospital Affiliated to Shanghai Jiao Tong University(approval No.12)on March 10,2011.
文摘AIM: To assess the clinical features and prognosis of 151 patients with extrahepatic metastases from primary hepatocellular carcinoma (HCC), and describe the treatment strategy for such patients. METHODS: After the diagnosis of HCC, all 995 consecutive HCC patients were followed up at regular intervals and 151 (15.2%) patients were found to have extrahepatic metastases at the initial diagnosis of primary HCC or developed such tumors during the follow-up period. We assessed their clinical features, prognosis, and treatment strategies. RESULTS: The most frequent site of extrahepatic metastases was the lungs (47%), followed by lymph nodes (45%), bones (37%), and adrenal glands (12%). The cumulative survival rates after the initial diagnosis of extrahepatic metastases at 6, 12, 24, and 36 mo were 44.1%, 21.7%, 14.2%, 7.1%, respectively. The median survival time was 4.9 mo (range, 0-37 mo). Fourteen patients (11%) died of extrahepatic HCC, others died of primary HCC or liver failure. CONCLUSION: The prognosis of HCC patients with extrahepatic metastases is poor. With regard to the cause of death, many patients would die of intrahepatic HCC and few of extrahepatic metastases. Although most of HCC patients with extrahepatic metastases should undergo treatment for the primary HCC mainly, treatment of extrahepatic metastases in selected HCC patients who have good hepatic reserve, intrahepatictumor stage (T0-T2), and are free of portal venous invasion may improve survival.

文摘Many studies have examined motor impairments using voxel-based lesion symptom mapping, but few are reported regarding the corresponding relationship between cerebral cortex injury and lower limb motor impairment analyzed using this technique. This study correlated neuro- nal injury in the cerebral cortex of 16 patients with chronic stroke based on a voxel-based lesion symptom mapping analysis. Neuronal injury in the corona radiata, caudate nucleus and putamen of patients with chronic stroke could predict walking speed. The behavioral measure scores were consistent with motor deficits expected after damage to the cortical motor system due to stroke. These findings suggest that voxel-based lesion symptom mapping may provide a more accurate prognosis of motor recovery from chronic stroke according to neuronal injury in cerebral motor cortex.

文摘背景心血管疾病(CVD)是腹膜透析(PD)患者死亡的主要原因,而营养不良是PD患者发生CVD及死亡的重要危险因素之一。预后营养指数(PNI)作为一种综合评估患者免疫、炎症和营养状态的指标,因其具有便利性与可靠性等优点,在肿瘤等多种疾病的预后评估中得到了广泛应用。然而,不同时间点的营养状态与PD患者预后之间的关系仍有待进一步探究。目的探讨PD患者首年PNI与CVD死亡之间的关系。方法本研究为多中心、回顾性观察性队列研究,纳入2000-01-01—2019-07-01在南方医科大学南方医院、南方医科大学顺德医院、佛山市第一人民医院以及赣州市人民医院4所中心置管并开始接受PD治疗的1640例PD患者作为研究对象。对患者进行随访,随访截止时间为2021-07-01,终点事件为CVD死亡并记录患者生存时间及具体死亡原因。应用限制性立方条图(RCS)分析PNI与PD患者CVD死亡风险之间的非线性关联;采用Kaplan-Meier法绘制PD患者的生存曲线,绘制PNI预测PD患者CVD死亡的受试者工作特征(ROC)曲线,并根据最佳截断值(cut-off=40.46)将患者分为低PNI组703例与高PNI组937例;采用Log-rank检验和Cox风险回归模型分析探讨PNI对PD患者CVD死亡的影响。结果本研究中位随访时间为30个月,随访期间共148例患者死亡,其中CVD死亡73例(49.32%)。RCS结果表明,PNI与CVD死亡事件呈线性关联(P for Nonlinear=0.655)。ROC曲线显示,PNI预测PD患者CVD死亡的曲线下面积(AUC)为0.717(95%CI=0.659~0.775,P<0.001),灵敏度为74.0%,特异度为58.6%。Kaplan-Meier生存分析结果显示,低PNI组CVD生存率低于高PNI组(χ^(2)=26.685,P<0.001)。多因素Cox风险回归模型分析,校正性别、年龄及CVD病史等混杂因素后,低PNI组仍是CVD死亡的独立预测因素(HR=7.76,95%CI=1.72~35.06,P=0.008),亚组分析结果仍稳健,无明显交互作用。结论PNI降低是PD患者CVD死亡的独立影响因素,PD首年PNI评分在评估PD患者预后有一定的指导意义。
文摘Objective:To investigate the association between magnetic resonance imaging(MRI)classification and symptom relief after uterine artery embolization(UAE)in patients with adenomyosis.Methods:Totally,73 patients with symptomatic adenomyosis who underwent UAE were retrospectively analyzed.Preoperative MRI classification was defined as:type Ⅰ,high signal on both T2-weighted images(T2WI)and T1-weighted images(T1WI);type Ⅱ,high signal only on T2WI,and type Ⅲ,high signal on neither T1WI nor T2WI.Dysmenorrhea was measured with the visual-analog scales and the degree of menorrhagia was measured according to the number of sanitary pads used in one menstrual cycle.Dysmenorrhea and menorrhagia were measured before UAE and 12 months after UAE.Results:The number of the type Ⅰ,Ⅱ,Ⅲ cases was 23,37,and 13,respectively.The baseline characteristics of the three groups exhibited no significant difference.The alleviation rates of dysmenorrhea among type Ⅰ,Ⅱ,Ⅲ cases were 73.9%,89.2%,and 84.6%,respectively(P=0.455).The alleviation rates of menorrhagia for type Ⅰ,Ⅱ,Ⅲ were 69.6%,78.4%,and 92.3%,respectively(P=0.714).Conclusion:Pre-procedure MRI classification and symptom relief after UAE exhibited no significant association.UAE has a favorable mid-term control on dysmenorrhea and menorrhagia among patients with adenomyosis.Preoperative MRI classification might not indicate symptom relief.More research is needed before changing clinical practice.
文摘Background: The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has greatly challenged public health worldwide. A growing number of studies have reported gastrointestinal (GI) symptoms. The study aimed to estimate the various digestive symptoms frequently reported in Covid-19 patients among the adult population of Bangladesh. Methods: In this descriptive, cross-sectional study, we enrolled confirmed patients with COVID-19 who were admitted to the COVID unit of Shaheed Suhrawardy Medical college hospital, Dhaka from July 2020 to December 2020. All patients were COVID confirmed by real-time polymerase chain reaction (RT-PCR) and were analyzed for clinical characteristics, laboratory findings and imaging study. Results: The study population consisted of 121 COVID-19-positive patients, among them, 57.85% were male and 42.15% female. The majority (43%) of the study population were in the age group of 31 - 40 years. The male to female ratio was 1.4:1. Nearly 94.2% of the sample population were married, among them 92.9% were male and 96.1% were female. Out of 121 Covid-19 patients, 30.65% had a contact history, 17.4% had a history of traveling or residing in an area reporting COVID-19 and 11.6% of family members were affected by Covid-19. Most of the patients had a fever (95%), cough (88.4%) and dyspnoea (43.8%), pneumonia (37.4%) and severe pneumonia (36.4%). In this study, 40% patients reported a digestive symptom including diarrhea 47.9%, vomiting 55.5%, loss of appetite 16.5%, abdominal pain 29.8%, abdominal bloating 24.8%, reflux 0%, jaundice 3.3%.
