目的 探讨代谢综合征(metabolic syndrome, MS)(指包括高血压,糖尿病,高脂血症和腹型肥胖的一组综合征)在中国南方老年病人的患病率、及其与心血管事件和痴呆关系。方法 本研究为一个中国南方老年人代谢综合征的横断面研究。我们采集了患者的病史、人口学和生化资料。对比生化资料、心血管事件、痴呆等疾病在MS组和非MS组中的差异,并使用Logistic回归分析来寻找MS的独立影响因子。结果 本研究共纳入206例患者。其中有92(44.66%)例患者符合代谢综合征的诊断标准。女性在MS组中35例(38.04%)明显高于在非MS组中28例(24.56%)。整体年龄(86.74± 6.10),在MS组(86.37±5.74)和非MS组(87.04±6.38)对比中无统计学意义。生化资料对比中,白细胞[(7.46±2.38) vs (6.46±2.35),P=0.003]和血肌酐[94.50(68.50, 129.33) vs 78.00(64.50, 99.75),P=0.004]在MS组中较高。Logistics单因素回归分析及多因素回顾分析提示白细胞、血肌酐和女性为MS的独立风险因子。心肌梗塞(35例,38.04%和心绞痛(28例, 24.56%)在MS组中明显高于非MS组中心肌梗塞(10例,8.77%)和心绞痛(39例,34.21%),两组比较有统计学意义,Logistics回归分析发现MS是心肌梗塞和心绞痛的独立影响因子;但是心衰和中风在两组对比中无统计学差别。痴呆(包括老年性痴呆和血管性痴呆)在MS组中明显低于非MS组:26例(28.26%)vs 50例(43.86%),提示MS可能对痴呆有预防作用。结论 MS在中国南方老年患者中普遍存在,女性、白细胞、血肌酐为MS的独立影响因子;MS是心肌梗塞和心绞痛的独立影响因子;MS中痴呆明显低于非MS组,可能对痴呆有预防保护性作用。

Objective To study the prevalence and correlation between the metabolic syndrome MS (including hypertension, diabetes, hyperlipidemia and obesity) with cardiovascular and dementia in the elderly people of south China. Methods This cross-sectional research studied metabolic syndrome of the elderly in south China. We collected the demographics and chemotic data and compared them in MS and non-MS group. And Logistic regression was used to analyze the independent factor of MS and the relationship between MS and the cardiovascular disease and dementia. Results This study included 206 patients and 92 (44.66%) of them were diagnosed as MS. 35 patients (38.04%) in MS group were female and 28 female cases (24.56%) in non-MS group. The mean age of the sample was (86.74±6.10) and the comparison between the MS group (86.37±5.74) and non-MS group (87.04±6.38) was not significantly different. White blood cell (WBC) (7.46±2.38 vs 6.46±2.35,P=0.003) and serum creatinine (Scr) was significantly [94.50(68.50,129.33) vs 78.00(64.50, 99.75),P=0.004]in MS group versus in non-MS group. Single factor and Multinomial logistic regression found WBC, serum creatinine and female gender were the independent risk factors of MS. Myocardial infarction (35, 38.04%) and angina (28, 24.56%) were significantly higher in MS group than that in non-MS group (10, 8.77%) and (39, 34.21%), respectively, with P<0.05. Logistic regression found MS was an independent risk factor of myocardial infarction and angina but not in heart failure and stroke. Dementia (including Alzheimer disease and vascular dementia) was found lower in MS group (26, 28.26%) than that in non-MS group (50, 43.86%), the difference was significant and this means MS could be protective for dementia. Conclusion MS is prevalent in the elderly of south China. Female gender, WBC and Scr were independent factors of MS; MS was the independent risk factor of myocardial infarction and angina; dementia was significantly lower in MS group, implying MS could be protective to dementia.

目的 通过比较利伐沙班、依若肝素和非抗凝治疗对全膝关节表面置换术后的疗效,分析全膝关节置换术后抗凝治疗的必要性、有效性及安全性。方法 选取2010年1月—2013年8月我科收治的全膝关节表面置换术的患者154例,按治疗方式分成利伐沙班组(A组)、依若肝素钠组(B组)及非抗凝组(C组)。观察各组术后静脉血栓栓塞发生率;术前及用药后凝血功能指标的变化;术后总失血量、显性失血量、隐性失血量;伤口情况;膝关节功能HSS评分。结果 A组与B组术后无静脉栓塞症发生,C组出现静脉栓塞症3例;A、B、C三组术前与术后凝血功能指标差异均无统计学意义(P>0.05);B组术后显性失血量高于A组(P<0.05);三组患者术前及术后各回访时间点膝关节功能HSS评分差异无统计学意义(P>0.05)。结论 抗凝药物预防全膝关节置换术后静脉血栓栓塞症的效果确切,利伐沙班与依若肝素疗效相当;抗凝治疗不会增加术后失血量及伤口并发症的发生率,且对术后膝关节中期功能恢复无影响。全膝关节表面置换术后使用抗凝治疗效果良好,安全性可。

Objective To compare the influence of anticoagulant therapy on the curative effect after total knee arthroplasty and evaluate the necessity, effectiveness and safety of anticoagulant therapy. Methods 154 patients after total knee arthroplastyfrom January 2010 to August 2013 in our department were divided into the rivaroxaban group (group A), the enoxaparin group (B group) and non anticoagulation group (group C) according to the treatments. It was observed that the postoperative venous thromboembolism incidence; changes of blood coagulation indexes before and after the operation; the total blood loss、dominant blood loss and hidden hemorrhage; the wound; the HSS score of knee function. Results None of postoperative venous thromboembolism occurred in group A and B, three cases of venous thromboembolism in group C;The differences of between preoperative and postoperative coagulation indexes in three groups had no statistical significance (P>0.05); Dominant blood loss in group B was significantly higher than that of group A (P<0.05); No statistical significance in the HSS scores of knee function of three group (P>0.05). Conclusion The effect of anticoagulant drugs on the prevention of venous thromboembolism after total knee arthroplasty is effective, same efficacy in the treatment with rivaroxaban or enoxaparin; anticoagulant therapy does not significantly increase the postoperative blood loss and the incidence of wound complications, does not influence the recovery of postoperative mid-term knee function. The use of anticoagulation therapy after total knee arthroplasty has good effect and be safety.

Objective To gain a deep understanding of the actual situation of occupational exposure in a general hospital in Heyuan City, assess health risks, propose effective control measures,and enhance the awareness of occupational protection among hospital staff to safeguard their health and safety. Methods A retrospective study was conducted to statistically analyze the occupational exposure events that occurred in a general hospital in Heyuan City from 2022 to 2023, in terms of exposure types, links, types of pathogens, occupational categories, and years of service. Results During the period from 2022 to 2023, a total of 93 cases of occupational exposure to blood-borne pathogens occurred in the general hospital, with sharp instrument injuries being the most common, accounting for 80 cases（86. 02%）; nurses accounted for the majority of occupational exposures, with 61 cases（65. 59%）; among the staff, those with a service time ≤ two years had the highest proportion of occupational exposures, with 71 cases（76. 34%）; the main occurrence of occupational exposures was in the processes of disposing of discarded sharp instruments and conducting inspections, treatments, and nursing operations, both accounting for 30 cases（32. 26%）; the main reason for occupational exposures was lack of protection, with 34 cases（36. 56%）; occupational exposures occurred mainly in general wards, with 37 cases（39. 78%）, followed by outpatient and emergency departments, both with 15 cases（16. 13%）; the types of infectious pathogens exposed in occupational exposures were mainly unknown, with 36 cases（38. 70%）, followed by hepatitis B, with 32 cases（34. 40%）; all staff who experienced occupational exposures received comprehensive exposure risk assessments,reasonable preventive medication measures, and regular health monitoring. Conclusions Hospital management departments need to enhance occupational safety training, particularly for nursing staff and junior-level employees, strictly enforce standard operating procedures, provide adequate protective equipment, improve medical device design, establish a comprehensive monitoring and reporting system, strengthen supervision, and manage to reduce the risk of occupational exposure and ensure the occupational safety of employees.
