目的 探讨乳腺癌改良根治术后影响局部复发与远处转移的相关因素。方法 对陕西省汉中市铁路中心医院略阳医院2000年3月至2007年3月期间行乳腺癌改良根治术且资料完整的637例原发性乳腺癌患者的临床资料进行回顾性分析。结果 66例（10.36%）患者术后发生局部复发和远处转移，其中局部复发50例（7.85%），远处转移16例（2.51%）；术后3～4年内发生复发与远处转移者47例（71.21%）。术后复发和远处转移与患者年龄、肿瘤大小、腋窝淋巴结转移情况、TNM分期、激素受体（ER/PR）表达情况及术后是否接受正规的辅助治疗有关，与患者有无家族史无关。结论 肿瘤大小、腋窝淋巴结转移情况、TNM分期、ER/PR表达情况及术后是否接受正规的辅助治疗是影响乳腺癌改良根治术后复发与远处转移的危险因素，重视乳腺癌术后随访，规范乳腺癌的手术方式，强化乳腺癌的综合治疗是降低乳腺癌改良根治术后复发与远处转移率的主要措施。
随着人口的老龄化，越来越多的有症状或无症状的冠心病患者需接受非心脏外科手术。接受非心脏外科手术而死亡的患者大约有50%是由于心脏并发症所致［1］。围手术期发生的心脏并发症大约5%～10%为心肌梗死，主要发生于术后头3天，其病死率很高，可达32%～69%［2，3］。术后发生心肌梗死或不稳定型心绞痛的患者发生心血管问题的几率增加20倍［4］。因此，如何评估非心脏外科手术患者的心脏危险性，如何预防围手术期心脏并发症的发生，已成为外科医生十分关注的一个问题。
Objective To investigate the relationship among central retinal vein occlusion (CRVO), major systemic diseases, ocular local diseases and related risk factors in Chinese population. Methods Seventeen-six patients with CRVO diagnosed by fundus fluorescein angiography (FFA) without any medical treatment were in CRVO group. Another 76 patients without CRVO or any vascular diseases of ocular fundus were in the control group who were matched with the ones in CRVO group to a one-to-one partnership according to the age and gender. The 2 groups were subdivided into le;45 years old (25 patients, 32.9%) and gt;45 years old (51 patients, 67.1%) subgroups according to the age, and 2 ischemia and non-ischema subgroups according to the results of FFA, respectively. The blood lipid, blood pressure, and fasting blood glucose were measured. The systematic diseases, ocular local diseases and the related risk factors were statistically analyzed and compared. Results The incidence of hypertension and hyperlipemia in CRVO group were significantly higher than that in the control group (Plt;0.001,P=0.001). There was no significant difference of cardiovascular diseases, cerebrovascular diseases, open-angle glaucoma, and smoking and drinking between the two groups(Pgt;0.05). In le;45 years old subgroups, there was no significant difference of each examination target between CRVO and control group(Pgt;0.05). In ischemia subgroups, except for the hypertension and hyperlipemia, the incidence of diabetes mellitus was obviously higher in CRVO group than that in the control group (hyperlipidemia:P=0.031; diabetes mellitus:P=0.024; diabetes mellitus: Plt;0.001). Conclusion Hypertension and hyperlipidemia are the systematic factors in Chinese population with occurrence of CRVO. In addition, diabetes mellitus is associated with ischemic CRVO. Timely diagnosis and treatment of the systematic diseases is important to the prevention and treatment for CRVO. (Chin J Ocul Fundus Dis, 2007, 23:159-162)
ObjectiveTo analyze the risk factors for electrical status epilepticus during sleep (ESES) in patients with self-limited epilepsy with centrotemporal spikes (SeLECTs) and to construct a nomogram model. MethodsThis study selected 174 children with SeLECTs who visited the Third Affiliated Hospital of Zhengzhou University from March 2017 to March 2024 and had complete case data as the research subjects. According to the results of video electroencephalogram monitoring during the course of the disease, the children were divided into non-ESES group (88 cases) and ESES group (86 cases). Multivariate logistic regression analysis was used to identify the risk factors for the occurrence of ESES in SeLECTs patients. ResultsThe multifactor Logistic regression analysis demonstrated that the EEG discharges in bilateral cerebral areas,types of seizure, epileptic seizures after initial treatment were the independent risk factors for the occurrence of ESES in SeLECTs. ConclusionBilateral distribution of electroencephalogram discharges before treatment, emergence of new seizure forms, and epileptic seizures after initial treatment are risk factors for the ESES in SeLECTs patients. The nomogram model constructed based on the above risk factors has a high degree of accuracy.
Abstract： Objective To analyze risk factors for perioperative mortality in the arterial switch operation (ASO), in order to provide better operation and decrease the mortality rate. Methods We enrolled 208 ASO patients including 157 males and 51 females at Fu Wai Hospital between January 1, 2001 and December 31, 2007. The age ranged from 6 h to 17 years with the median age of 90 d and the weight ranged from 3 kg to 43 kg with the median weight of 5 kg. Among the patients, 127 had transposition of great artery (TGA) with ventricular septal defect (VSD), and 81 patients had TGA with intact ventricular septum (IVS) or with the diameter of VSD smaller than 5 mm. Coronary anatomy was normal (1LCX2R) in 151 patients and abnormal in the rest including 15 patients with single coronary artery, 6 with intramural and 36 with inverse coronary artery. Preoperative, perioperative and postoperative clinical data of all patients were collected to establish a database which was then analyzed by univariate analysis and multivariate logistic regression analysis to find out the risk factors formortality in ASO. Results There were 24 perioperative deaths (11.54%) in which 12 died of postoperative infection with multiple organ failure (MOF), 10 died of low cardiac output syndrome, 1 died of pulmonary hypertension, and 1 died of cerebral complications. Among them, 20 patients (18.30%) died in early years from 2001 to 2005, while only 4 (4.00%) died in the time period from 2006 to 2007, which was a significant decrease compared with the former period (Plt;0.05). The univariate analysis revealed that cardiopulmonary bypass (CPB) time was significantly longer in the death group than in the survival group（236±93 min vs. 198±50 min, P=0.002）, and occurrence of major coronary events (33.3% vs. 2.2%, P=0.000) and unusual coronary artery patterns（33.3% vs. 6.5%,P=0.000） were much more in the death group than in the survival group. Multivariate logistic regression analysis showed that early year of [CM(159mm]operation (OR=7.463, P=0.003), unusual coronary artery patterns (OR=6.303,P=0.005) and occurrence of majorcoronary events (OR=17.312, P=0.000) were independent predictors for perioperative mortality. Conclusion The ASO can be performed with low perioperative mortality in our hospital currently. Occurrence of major coronary events, unusual coronary artery patterns and year of surgery before 2006 are independent predictors for perioperative mortality.
Objective To investigate the risk factors of perioperative red blood cells transfusion for coronary artery bypass grafting (CABG) surgery. Method We retrospectively analyzed the clinical data of 534 patients underwent CABG in our hospital from January to March 2014 year. Those patients were divided into two groups:an on-pump coronary artery bypass grafting group (on-pump group) and an off-pump coronary artery bypass grafting group (off-pump group). There were 185 males and 54 females with a mean age of 59.1±9.4 years in the on-pump group. There were 233 males and 62 females with a mean age of 60.3±8.5 years in the off-pump group. Preoperative data, the relative parameters of extracorporeal circulation, the quantity of red blood cells transfusion of those two groups were compared. risk factors associated with red blood cells transfusion were evaluated by multivariate logistic regression analysis. Results The risk factors of perioperative red blood cells transfusion were age (OR=1.04, 95% CI 1.02-1.07, P=0.001) , weight (OR=0.95, 95% CI 0.93-0.97, P<0.001) , smoking (OR=0.61, 95% CI 0.39-0.94, P=0.027) , preoperative level of HCT (OR=0.90, 95% CI 0.85-0.96, P=0.001) and cardiopulmonary bypass (CPB) (OR=4.90, 95% CI 3.11-7.71, P<0.001) . During CPB, the nadir hemoglobin (nHb) (OR=0.63, 95% CI 0.47-0.84, P=0.002) was the only independent risk factor of red blood cell transfusion. Conclusions Age, weight, non-smoking, preoperative level of HCT, CPB are the risk factors for patients underwent CABG perioperatively and the lowest level of Hb in CPB is an independent risk factor of perioperative red blood cells transfusion.
ObjectiveTo analyze the prevalence and risk factors of metabolic syndrome (MS) after adult liver transplantation (LT) recipients. MethodsThe clinicopathologic data of patients with survival time ≥1 year underwent LT in the People’s Hospital of Zhongshan City from January 1, 2015 to August 31, 2020 were analyzed retrospectively. The logistic regression model was used to analyze the risk factors affecting MS occurrence after LT, and the receiver operating characteristic (ROC) curve was used to evaluate the optimal cutoff value of the index of predicting MS occurrence and its corresponding evaluation effect. ResultsA total of 107 patients who met the inclusion criteria were collected in this study. Based on the diagnostic criteria of MS of Chinese Medical Association Diabetes Association, the occurrence rate of MS after LT was 32.7% (35/107). Multivariate logistic regression analysis showed that the increased age of the recipient [OR (95%CI)=1.106 (1.020, 1.199), P=0.014], preoperative increased body mass index [OR (95%CI)=1.439 (1.106, 1.872), P=0.007] and blood glucose level [OR (95%CI)=1.708 (1.317, 2.213), P<0.001], and with preoperative smoking history [OR (95%CI)=5.814 (1.640, 20.610), P=0.006] and drinking history [OR (95%CI)=5.390 (1.454, 19.984), P=0.012] increased the probability of MS after LT. The areas under the ROC curve (AUC) corresponding to these five indexes were 0.666, 0.669, 0.769, 0.682, and 0.612, respectively. The corresponding optimal cutoff values of three continuous variables (recipient’s age, preoperative body mass index, and blood glucose level) were 53 years old, 23.1 kg/m2, and 6.8 mmol/L, respectively. The AUC of combination of the above five indexes in predicting occurrence of MS was 0.903 [95%CI (0.831, 0.952)], and the sensitivity and specificity were 80.0% and 90.3%, respectively. ConclusionsIncidence of MS after adult LT recipient is not low. For recipients with preoperative hyperglycemia, obese, elderly, histories of drinking and smoking before LT need to pay attention to the early detection and early intervention of MS.
Objective The purpose of the current research was to analyze the relevant risk factors for short-term death in patients with chronic obstructive pulmonary disease (COPD) and heart failure (HF), and to build a predictive nomogram. Methods We conducted a retrospective analysis of clinical data from 1 323 COPD and HF comorbidity patients who were admitted to the Affiliated Hospital of Southwest Medical University from January 2018 to January 2022. Samples were divided into survival and death groups based on whether they died during the follow-up. General data and tested index of both groups were analyzed, and the discrepant index was analyzed by single factor and multiple factor Logistic regression analysis. R software was applied to create the nomogram by visualizing the results of the regression analysis. The accuracy of the results was verified by C index, calibration curve, and ROC curve. Results The results from the multiple factor Logistic regression analysis indicated that age (OR=1.085, 95%CI 1.048 to 1.125), duration of smoking (OR=1.247, 95%CI 1.114 to 1.400), duration of COPD (OR=1.078, 95%CI 1.042 to 1.116), comorbidity with respiratory failure (OR=5.564, 95%CI 3.372 to 9.329), level of NT-proBNP (OR=1.000, 95%CI 1.000 to 1.000), level of PCT (OR=1.153, 95%CI 1.083 to 1.237), and level of D-dimer (OR=1.205, 95%CI 1.099 to 1.336) were risk factors for short-term death of COPD and HF comorbidity patients. The level of ALB (OR=0.892, 95%CI 0.843 to 0.942) was a protective factor that was used to build the predictive nomogram with the C index of 0.874, the square under the working characteristics curve of the samples of 0.874, the specify of 82.5%, and the sensitivity of 75.0%. The calibration curve indicated good predictive ability of the model. Conclusion The nomogram diagram built by the current research indicated good predictability of short-term death in COPD and HF comorbidity patients.
ObjectiveTo observe and analyze the risk factors of retinopathy in patients with hypertension in pregnancy.MethodsA retrospective clinical study. From January 2018 to December 2019, 260 patients with hypertension during pregnancy who were hospitalized in the Obstetrics Department of the Third Affiliated Hospital of Guangzhou Medical University were included in the study. All patients underwent fundus color photography examination. Their age, gestational age, course of hypertension, past history, number of pregnancy and childbirth, pre-pregnancy body mass index (BMI) and laboratory blood routine, alanine aminotransferase, aspartate aminotransferase, and urea Nitrogen, creatinine, uric acid, serum albumin concentration, and 24-hour urine protein concentration and urine protein content examination results were collected. Among the 260 patients, there were 60 and 200 patients with or without retinopathy in the fundus, respectively. Patients were divided into retinopathy group and no retinopathy group. The comparison of quantitative data between groups was performed by independent sample t test; the comparison of grade data was performed by Mann-Whitney U nonparametric test. The variable with statistical difference between the two groups was the independent variable, and the two-class logistic regression analysis was performed.ResultsGestational week (t=4.875), pre-pregnancy BMI (t=2.779), highest systolic blood pressure (t=－4.799), lowest systolic blood pressure (t=－4.797), highest diastolic blood pressure (t=－4.226), minimum diastolic blood pressure (t=－4.226), low and high platelet values and their fluctuations (t=7.701, 2.504, －6.083), serum albumin concentration (t=13.255), aspartic acid transaminase (t=－2.272), urea nitrogen (t=－5.117), creatinine (t=－2.735), uric acid (t=－2.130), 24-hour urine protein concentration (t=－7.801) and 24-hour urine protein (t=－7.567) were compared. The difference was statistically significant (P＜0.05). Logoistic regression analysis showed that pre-pregnancy BMI, maximum systolic blood pressure, low platelet value, and serum albumin were related to the occurrence of retinopathy of hypertension in pregnancy (P＜0.05).ConclusionHigh systolic blood pressure, low platelets, and low serum albumin are the risk factors for the occurrence of retinopathy of hypertension in pregnancy.
