A retrospective analysis was performed,by comparing the survival rate calculated by the Kaplan-Meier method with the rate of recurrence or metastasis.Results The standard posteroanterior and lateral chest radiographs were reliable means of detection of most thymomas. Myasthenia gravis was the most commonly paraneoplastic disease (25.0%,29/116). The extensive radical resection was beneficial for reducing the rate of recurrence of stage Ⅰ or stage Ⅱ thymomas (χ 2=4.941,P =0.0219). The survival time could be prolonged by postoperative radiotherapy and chemotherapy. There was a strong correlation between the clinical stage and the histological classification (according to MH classification),through which the invasive behavior of thymoma could be predicted (χ 2=19.76,P =0.007,RR=1.47). The 3- 5- and 10-year survival rates were 81.2%,67.9%,and 40.5%,respectively. Statistical analysis showed a significant negative correlation between the stage and the survival rate (χ 2=29.73,P =0.0000,RR=0.15). Conclusion The prognosis of thymoma depends mainly on the histological classification,clinical stage and multimodality treatment rather than on the paraneoplastic diseases.展开更多

文摘Objective To study the diagnosis and treatment of thymoma and to assess its prognostic factors.Methods The clinical data of 116 patients with thymoma were collected. A retrospective analysis was performed,by comparing the survival rate calculated by the Kaplan-Meier method with the rate of recurrence or metastasis.Results The standard posteroanterior and lateral chest radiographs were reliable means of detection of most thymomas. Myasthenia gravis was the most commonly paraneoplastic disease (25.0%,29/116). The extensive radical resection was beneficial for reducing the rate of recurrence of stage Ⅰ or stage Ⅱ thymomas (χ 2=4.941,P =0.0219). The survival time could be prolonged by postoperative radiotherapy and chemotherapy. There was a strong correlation between the clinical stage and the histological classification (according to MH classification),through which the invasive behavior of thymoma could be predicted (χ 2=19.76,P =0.007,RR=1.47). The 3- 5- and 10-year survival rates were 81.2%,67.9%,and 40.5%,respectively. Statistical analysis showed a significant negative correlation between the stage and the survival rate (χ 2=29.73,P =0.0000,RR=0.15). Conclusion The prognosis of thymoma depends mainly on the histological classification,clinical stage and multimodality treatment rather than on the paraneoplastic diseases.

文摘Objective：To determine the impact of adjunctive Buchang Naoxintong Capsule（步心脑心通胶囊,NXT） on dual antiplatelet therapy in patients with cytochrome P450 2C19＊2（CYP2C19＊2） polymorphism undergoing percutaneous coronary intervention（PCI）.Methods：Ninety patients with CYP2C19＊2 polymorphism were enrolled,and their genotypes were confirmed by polymerase chain reaction（PCR）.The patients were randomly assigned to receive either adjunctive NXT（triple group,45 cases） or dual antiplatelet therapy（dual group,45 cases） using a computer-generated randomization sequence and sealed envelopes.Platelet function was assessed at baseline and 7 days after treatment with conventional aggregometry.Subsequent major adverse cardiovascular events（MACE,including sudden cardiac arrest and acute coronary syndrome） were recorded during a 12-month followup.Results：Baseline platelet function measurements were similar in both groups.After 7 days,percent inhibitions of maximum platelet aggregation and late platelet aggregation were significantly greater in the triple versus dual group（42.3%±16.0%vs.20.8%±15.2%,P〈0.01,and 54.7%±18.3%vs.21.5%±29.2%,P〈0.01,respectively）.During the 12-month follow-up,the rate of subsequent MACE（6/45） was significantly lower in the triple group compared with the dual group（14/45;P〈0.05）.Conclusion：Adjunctive NXT to maintenance dose clopidogrel（75 g） could enhance the antiplatelet effect and decrease subsequent MACE in patients with the CYP2C19＇2polymorphism undergoing PCI.

文摘Background and Objectives:The current study aimed to explore the effect of nutritional prehabilitation on the clinical prognosis of elderly patients undergoing abdominal cancer surgery.Methods and S tudy Design:A ret rospective study was conducted,where participants were divided into two groups based on whether they received oral nutritional supplementation at the first outpatient visit.The nutritional prehabilitation group(n=41)adopted a nutritional prehabilitation mode(a standard energy intake of 25-30 kcal/kg·d was recommended).While the con trol group(n=55)received routine care.All patients underwent laparoscopic surgery according to the National Comprehensive Cancer Network(NCCN)guidelines.Changes in nutritional status,complications,psychological status,symptoms,hospitalization days,and expenditures were compared between the two groups.Results:Both groups of patients experienced weight loss.However,the decline in body weight in the prehabilitation group was less than that in the control group(-1.88 vs.-2.56 kg,p<0.001).In the comparison of nutritional prehabilitation group and control group,significant improvements were observed in the Hospital Anxiety Scale scores(5 vs.5,p=0.01)and MD Anderson Symptom Inventory scores(3 vs.0,p<0.001)respectively.The infection rate in the nutritional prehabilitation group was lower than that in the control group(17.1%vs.36.4%,p=0.04).Addition ally,patients in the nutritional prehabilitation group had significantly fewer hospitalization days at discharge(14.3 vs.17.1 days,p=0.03).Conclusions:In elderly patients undergoing abdominal cancer surgery,a nutrition al prehabilitation model may help maintain better physical and mental status,reduce infection rates,and shorten hospitalization days.
