Objective To analyze the current status of metabolic syndrome (MetS) and its influencing factors among physical examination population aged 60 years old and above in Chengdu, and to provide evidence for the screening and management of MetS in people aged 60 years old and above. Methods Retrospective analysis of the data of people aged 60 years old and above who participated in physical examination in the North District of the Department of Health Management of Sichuan Provincial People’s Hospital between January 2018 and December 2020. According to whether the elderly occurred to have MetS, they were divided into MetS group and non-MetS group, to observe the distribution of MetS in different genders and different age groups, and to analyze the influencing factors of MetS by multivariate logistic regression. Results A total of 10 335 elderly were enrolled, 2 769 cases (26.79%) in MetS group and 7 566 cases (73.21%) in non-MetS group. Except for gender and low-density lipoprotein cholesterol (LDL-C) (P>0.05), there were significant differences in other general data between the two groups (P<0.05). There was a statistically significant difference in the detection rate of MetS among different age groups (χ²=64.332, P<0.001). In MetS group, 951 cases (34.34%) of abdominal obesity, 716 cases (25.86%) of high fasting blood glucose (FBG), 1 938 cases (69.99%) of hypertension, 1 011 cases (36.51%) of high triglycerides (TG) and 303 cases (10.94%) of low high-density lipoprotein cholesterol (HDL-C) were detected. Except hypertension and high TG (P>0.05), there were statistically significant differences in the detection rates of abdominal obesity, high FBG and low HDL-C among different genders in MetS (P<0.05). Except hypertension (P<0.05), there was no significant difference in the detection rates of MetS abdominal obesity, high FBG, low HDL-C and high TG in different age groups (P>0.05). Logistic regression analysis showed that body mass index [odds ratio (OR)=1.055, 95% confidence interval (CI) (1.014, 1.097), P=0.008], systolic blood pressure [OR=1.032, 95%CI (1.027, 1.037), P<0.001], diastolic blood pressure [OR=0.992, 95%CI (0.985, 1.000), P=0.049], FBG [OR=1.853, 95%CI (1.764, 1.947), P<0.001], TG [OR=3.787, 95%CI (3.352, 4.278), P<0.001], hemoglobin [OR=0.991, 95%CI (0.986, 0.996), P<0.001], waist circumference [OR=1.158, 95%CI (1.141, 1.175), P<0.001], HDL-C [OR=0.243, 95%CI (0.170, 0.346), P<0.001], total cholesterol [OR=0.615, 95%CI (0.490, 0.773), P<0.001], LDL-C [OR=1.594, 95%CI (1.303, 1.948), P<0.001], and uric acid [OR=1.001, 95%CI (1.000, 1.002), P=0.042] were related to MetS. Conclusions The prevalence of MetS is high among people aged 60 years old and above who undergo physical examination. Routine screening should be carried out during physical examination to take measures to intervene the controllable risk factors, so as to improve the health level of the region.
Objective To analyze the correlation between HLA-A and B genotypes and maculopapular exanthema (MPE) caused by Carbamazepine (CBZ) and Oxcarbazepine (OXC), and to explore the genetic risk factors of MPE. Methods Patients with MPE (rash group) and patients without MPE (non-rash group) after taking CBZ or OXC were retrospectively collected from January 2016 to October 2021 in the Second Affiliated Hospital of Guangzhou Medical University. DNA was extracted from peripheral blood. HLA-A and HLA-B alleles were sequenced by high resolution sequencing, and a case-control study was conducted to analysis the correlations between MPE and HLA genotypes. Results A total of 100 patients with CBZ-MPE, 100 patients with CBZ-tolerant, 50 patients with OXC-MPE, and 50 patients with OXC-tolerant were collected. There was no significant difference in age and sex between CBZ, OXC rash groups and non-rash groups The average latency of CBZ-rash group was (11.31±11.00) days and their average dosage was (348.46±174.10) mg; the average latency of OXC-rash group was (11.67±10.34) days and their average dosage was (433.52±209.22) mg [equivalent to CBZ (289.01±139.48 mg)], showing no significant difference in latency and dosage between CBZ and OXC (P>0.05). The positive rates of HLA-A*24:02 and A*30:01 in CBZ-rash group were 28% and 6%, respectively, which were significantly higher than those in CBZ-non rash group (16% and 0%, both P=0.04). The positive rate of HLA-B*40:01 in CBZ-rash group was 18%, which was significantly lower than that in CBZ-non rash group (40%, P<0.001). No association between HLA-A or B genotype and OXC-rash was found yet. When pooled, it was still found that the positive rates of HLA-A*24:02 and A*30:01 in the rash group were higher than those in the non-rash group, while the positive rate of HLA-B*40:01 in the rash group was lower than that in the non-rash group, and the difference was statistically significant (P<0.05). Conclusions HLA-A*24:02 and A*30:01 were associated with MPE caused by CBZ, and may be common risk factors for aromatic antiepileptic drugs.
Objective To study the therapeutic effect of combining vacuum seal ing drainage (VSD) with gluteus maximus myocutaneous flap on the repair of soft tissue defect caused by the resection of sacral tumors. Methods From June2007 to June 2008, 6 patients with skin and soft tissue necrosis in the sacrococcygeal region, deep infection, and formation of cavity at 3-6 weeks after sacral tumors resection were treated. There were 4 males and 2 females aged 17-51 years old. The size of skin and soft tissue defects ranged from 15 cm × 11 cm × 6 cm to 20 cm × 18 cm × 7 cm. Every patient underwent VSD treatment for 7-10 days, and the recombinant bovine bFGF was injected into the wound intermittently for 7-14 days (250-300 U/ cm2 once, twice daily). The wound was repaired by either the gluteus maximus myocutaneous flap (5 cases) or the lumbar-gluteus flap (1 case), and those flaps were 9 cm × 9 cm-20 cm × 18 cm in size. The donor site were sutured or repaired with spl itthickness skin graft. Results All the flaps survived uneventfully. The wound healed by first intention in 5 cases, but 1 case suffered from fat l iquefaction 2 weeks after operation and healed after drainage and dressing change. All the donor sites healed by first intention, and all the skin grafts survived uneventfully. All the patients were followed up for 6-10 months, there was no relapse of sacral tumor, and the flaps showed no obvious swell ing with good color and elasticity. Conclusion With fewer compl ications, the combination of VSD and gluteus maximus myocutaneous flap is a safe and rel iable operative method for repairing the skin and soft tissue defects caused by the resection of sacral tumors.
