Objective This study was performed to find the association of the severity of coronary artery disease with ordinary risk factors for CHD and left ventricle heart function in patients with CHD. Methods Selective coronary angiography were carried on 305 consecutive patients admitted to our hospital from December 2008 to April 2009. The severity of coronary disease was accessed by the Gensini scoring system. These patients were divided into two groups, patients with CHD group (251 cases) and control group (patients without CHD) (54 cases) , to compare the difference of ordinary risk factors for CHD between the two groups. Multiple linear regression analysis was used to analyze the association of the severity of coronary artery disease with ordinary risk factors for CHD. We also used linear correlation analysis to investigate the association of the severity of coronary artery disease with left ventricle ejection fraction in patients with CHD. Results The two groups had statistically difference on age, sex, smoking index, hypertension prevalence rate, serum glucose abnormal prevalence rate, diabetes prevalence rate, and metabolic syndrome prevalence rate( P < 0.05). We found that age (β_1 =0.251, P <0.01), sex (β_2 =0.235, P < 0.01), LDL-C concentration (β_3 = 0.241,P <0.01), duration of diabetes (β_4 =0.226, P <0.01) went into multiple linear regression model. We also found the severity of coronary artery disease had a negative correlation ( r = -0. 362, P <0.01) with left ventricle ejection fraction in patients with CHD. Conclusion When we decide to cany out coronary angiography on susceptible patients, we should consider their age, sex, smoking index, whether had hypertension, serum glucose abnormal, diabetes, metabolic syndrome or not. Age, sex, LDLC concentration, duration of diabetes affect severity of coronary artery stenosis independently. Left ventricle ejection function will decrease as coronary atherosclerosis continues.

Objective:To investigate the factors related to recurrence and prognosis of retroperitoneal liposarcoma.Method:The clinical data of patients with primary retroperitoneal liposarcoma who underwent surgical treatment in the First Affiliated Hospital of Zhengzhou University from June 2011 to January 2020 were analyzed retrospectively. There were 42 males and 47 females and patients’median age was 53 (26-78). Sixty-five cases were treated by operation in our hospital, and 24 cases were primarily treated by the operation in another hospital. The clinical manifestations of the initial diagnosis included retroperitoneal mass in 41 cases, abdominal distension in 12 cases, abdominal pain in 10 cases, fever in 11 cases, nausea, vomiting and poor appetite in 8 cases, frequent urination and dysuria in 6 cases, and bilateral lower limb edema in 1 case. Preoperative CT imaging showed that the tumor body was located in the retroperitoneal kidney area in 58 cases, while in the retroperitoneal space or the pelvic extraperitoneal space in 31 cases. There were 55 single cases and 34 multiple cases. The median tumor length was 20(3-52) cm. Among the primarily treated 65 patients, 47(72.3%) were considered as primary retroperitoneal liposarcoma by preoperative imaging examination. Among the 89 patients treated by surgery, 78 underwent endoscopic surgery, among which 21 underwent laparoscopic surgery, 38 cases of retroperitoneal laparoscopic surgery, 19 cases of Da Vinci robot-assisted laparoscopic surgery. Open operation was performed in 11 cases. There were 87 patients undergoing radical resection and 2 patients undergoing palliative resection. Forty-two patients underwent intraoperative combined resection of the adjacent organs. The recurrence and survival status of patients were followed up.Results:All the 89 patients underwent the operation successfully, with the median operative blood loss of 200 (10-2000) ml. There were 23 cases being diagnosed of well differentiated liposarcoma, 40 cases of dedifferentiated, 20 cases of myxoid/round, 5 cases of myxoid liposarcoma, and 1 cases of mixed type. Pathologically, there 42 cases with low grade histology and 47 cases with high grade histology. In this study, 89 patients were followed up for 3 to 108 months, and the median follow-up time was 28 months. The 5-year recurrence free survival rate, disease-free survival rate and overall survival rate of the patients were 16.7%, 16.1% and 52.6%, respectively. There were 57 patients presenting local recurrence, 1 patient of lung metastasis, and 1 patient of liver metastasis, and the median disease-free survival time was 24 months. There were 42 patients died of the disease, with a median survival time of 64 months. Univariate analysis showed that intraoperative blood loss( P<0.01), whether multiple cases( P<0.01), pathologic types( P<0.01), and histological grades ( P<0.01) were related to disease-free survival.The intraoperative blood loss( P<0.01), multiple cases( P<0.05), pathologic types ( P<0.05), and recurrence ( P<0.01)were related with overall survival. Gender, age, tumor size, tumor location, whether primary surgery, radical resection or combined resection of adjacent organ had no effect on the prognosis of patients ( P>0.05). Cox regression model multivariate analysis revealed that surgical bleeding ( RR=2.360, 95% CI 1.313-4.241, P=0.004), multiple tumor ( RR=1.899, 95% CI 1.068-3.375, P=0.029), and pathological type ( RR=4.976, 95% CI 1.622-15.264, P=0.005) were independent factors affecting disease-free survival. The recurrence was an independent factor affecting the overall survival of patients ( RR=31.495, 95% CI 1.062-933.684, P=0.046). Conclusions:Retroperitoneal liposarcoma is a rare disease with high recurrence rate. The intraoperative blood loss, whether multiplicity and pathological type are independent factors affecting the disease-free survival, and recurrence is independent factors affecting the overall survival.

Objective To analyze effect of the hospital-home care model in elderly patients with diabetes.Methods A total of 110 elderly patients with diabetes were as research objects, and were divided into control group and observation group according to the admission number, with 55 cases in each group.Control group was given conventional discharge guidance and the observation group implemented hospital-family nursing mode.Quality of life and control blood sugar levels after discharge after intervention for 1 month were compared.Results After intervention for 1 month, the observation group quality had higher psychological state, housework activities, and family relationship, and lower average fasting blood glucose and postprandial 2 h blood glucose than that of control group (P<0.05).Conclusion Hospital-home care model for elderly patients with diabetes can effectively improve patient''s quality of life after discharge and control blood sugar levels.
