Effects of preoperative lipid metabolism indexes on the prognosis of patients with non-muscular invasive bladder cancer / 现代泌尿外科杂志

【Objective】 To investigate the effects of preoperative lipid metabolism level on the postoperative prognosis of non-muscular invasive bladder cancer (NMIBC). 【Methods】 Clinical data of NMIBC patients who underwent surgical treatment in our hospital during Mar.2014 and May 2021 were retrospectively analyzed. Based on receiver operating characteristic (ROC) curve, the optimal cutoff values of all lipid metabolism indicators were determined and patients were classified accordingly. The independent risk factors for postoperative recurrence were identified with Cox regression model. The survival was analyzed with Kaplan-Meier, and recurrence-free survival (RFS) was compared using log-rank tests. A recurrence risk prediction model was established based on the high-density lipoprotein (HDL) and other clinic pathological factors and the accuracy of prediction was evaluated with the area under the ROC curve (AUC). 【Results】 Cox multivariate analysis showed HDL, tumor number, tumor size and histological grade were independent risk factors for recurrence (P<0.05). Kaplan-Meier analysis showed that RFS was significantly longer in the high-HDL group than in the low-HDL group (P<0.001). Incorporating HDL, tumor number, tumor size, histological grade, and tumor stage into the recurrence risk model, the AUC was 0.706, and internal cross validation showed the AUC was 0.711. 【Conclusion】 Preoperative HDL is an independent risk factor affecting the RFS of patients with NMIBC, and combining it with clinic pathological factors will improve the prediction of tumor recurrence.

Curative effect of surgery within 48 hours after hip fracture in elderly patients / 中华骨科杂志

Objective To compare the clinical effects of surgery within and over 48 hours for hip fractures in elderly pa?tients. Methods From May 2017 to April 2018, 47 patients over 75 years old with hip fracture were operated in our hospital and met with inclusion criteria. The patients were divided into two groups: within 48?hour group and over 48?hour group according to study design. In the within 48?hour group, there were 22 patients including 5 males and 17 females, aged from 76 to 97 years, with an average age of 83.6±5.0 years, and there were 10 femoral neck fractures (3 total hip arthroplasty, 7 hemiarthroplasty) and 12 femoral intertrochanteric fractures (proximal femoral intramedullary nail fixation). There were 25 patients (7 males and 18 females) in the over 48?hour group, aged from 76 to 98 years, with an average age of 83.8±5.8 years, and there were 10 femoral neck frac?tures (2 total hip arthroplasty, 8 hemiarthroplasty) and 15 femoral intertrochanteric fractures (proximal femoral intramedullary nail fixation). At the end of the follow?up period, the clinical data of the two groups were compared. The differences in the length of stay, cost of stay (excluding implants), postoperative complications within 1 month, hip function score (Harris score) within 1 month and 3 months, and mortality within 3 months and at the end of follow?up were analyzed. Results Both groups were fol?lowed up for 12 to 24 months, with an average of 17.7 months. The hospitalization time (7.9±3.0 d), hospitalization expenses (16 627.5± 6 428.8 yuan), the incidence of early complications after operation (59.1% ) and Harris score (80.9 ± 8.6) in the within 48?hour group were significantly better than those in the over 48?hour group (12.3±4.1 d, 23 799.0±9 785.3 yuan, 88.0%, 71.1±9.2, respec?tively). At 3 months after operation, there was no significant difference in Harris score between the two groups (83.9±7.3 in within 48?hour group and 82.3±8.9 in over 48?hour group; t=0.668, P=0.507). Within 3 months, there was no death inwithin 48?hour group, but 2 in over 48?hour group; and 1 in within 48?hour group at the last follow?up.

Analysis of association between γ-glutamyltransferase and risk of metabolic syndrome in health checkup cohort / 中华健康管理学杂志

Objective To analyze the relationship between baseline serum γ?glutamyltransferase (GGT) and risk of the metabolic syndrome (MS). Method A total of 4 935 adults from health checkup population in Shenzhen were enrolled into a 10?year follow?up study, of these adults 81.84%were male and 18.16% were female, the average age was 60.54 ± 10.38 years.The follow?up outcome measure was the occurrence of MS. The proportional hazards model was adopted to calculate the hazard ratios (HR) and 95%confidence intervals (95%CI) to analyze the association of GGT with the development of MS. Reslut The mean follow up period was 5.0 ± 2.9 years, and there were 24 713 person?years of follow?up, and 1 689 subjects developed MS. During the follow?up, the cumulative incidence and incidence density of MS were 34.22%and 68.34/1 000 person?years, respectively. For both genders, the association between GGT and MS presented dose?response relationship trend (male: M?C χ2=32.78, P<0.001; female: M?C χ2=18.80, P<0.001). After adjusting for age, gender, body mass index, systolic blood pressure, diastolic blood pressure, high?density lipoprotein cholesterol, low?density lipoprotein cholesterol, triglycerides, uric acid and fasting blood glucose in Cox regression model, the HR for MS in quartiles 3 and 4 level of GGT was 1.45 (95%CI:1.08-1.85) and 1.52 (95%CI:1.15-1.99), respectively. Conclusion The GGT level could be an important risk factor and predictor for the development of MS.
