Objective To explore the clinical characteristics of metabolic disorder and the incidence rate of metabolic syndrome (MS) in the patients with posthepatitic cirrhosis.Methods Four hundred and fifty-five patients with posthepatitic cirrhosis were included in the study and divided into hepatitis B related cirrhosis group (LCB group,351 cases) and hepatitis C related cirrhosis group (LCC group,104cases).The prevalence of metabolic disorder was recorded and the characteristics of posthepatitic cirrhosis with MS and without MS were compared and analysed.Results The prevalence of hyperglycemia,hypertension,hyperlipemia,obesity and MS in the posthepatitic cirrhosis patients was 46.59% (212/455),15.16% (69/455),15.38% (70/455),22.64% ( 103/455),12.53% (57/455) respectively.The prevalence of MS in LCB and LCC was 8.26% (29/351) and 26.92% (28/104).The levels of body mass index (BMI),fasting blood glucose,hypertension,cholesterol,aminotransferase (ALT) in LCB with MS patients were significantly higher than those in LCB without MS patients.There were no differences in the levels of HBeAg and HBV DNA between LCB with MS patients and LCB without MS patients.The levels of BMI,hypertension,triglyceride in LCC with MS patients were significantly higher than those in LCC without MS patients.There were no differences in fasting blood glucose,cholesterol and ALT between LCC with MS patients and LCC without MS patients.Logistic regression revealed that BMI was the independent factor in LCB and LCC with MS.Conclusions The prevalence of hyperglycemia and obesity are higher in LCB and LCC.The incidence rate of MS in LCB is less than that in the general population,while the incidence rate of MS in LCC is significantly higher than that in the general population,and it's nothing to do with the viral replication.BMI is an important factor affected in posthepatitic cirrhosis with MS.

Objective:To evaluate our self-designed guide device for Kirschner-wire placement in the surgery for paediatric fractures of supracondylar humerus.Methods:A retrospective study was conducted of the 117 children who had been treated for fractures of supracondylar humerus at Department of Orthopedics, The First People's Hospital of Huaian Affiliated to Nanjing Medical University from March 2019 to January 2023. There were 64 boys and 53 girls with an age of (5.8±1.5) years. By the Gartland classification, there were 67 fractures of type Ⅱ and 50 fractures of type Ⅲ. The time from injury to operation averaged (48.5±10.8) hours. The children were divided into 2 groups according to how their Kirschner-wires were placed. In the control group of 58 cases, external percutaneous Kirschner-wire placement was assisted using a syringe needle; in study group of 59 cases, external percutaneous Kirschner-wire placement was assisted using our self-designed guide device for Kirschner-wire placement. The operation time, rate of one-time placement of disposable K-wire, intraoperative fluoroscopy frequency, Baumann angle, carrying angle, fracture healing time, Flynn score of elbow joint function at the final follow-up, and postoperative complications were compared between the 2 groups.Results:There was no significant difference in the preoperative general data between the 2 groups, indicating comparability ( P>0.05). The 117 pediatric patients were followed up for (15.3±3.2) months after operation. The operation time [(30.6±4.5) min] and intraoperative fluoroscopy frequency [(15.6±2.1) times] in the study group were significantly less than those in the control group [(40.6±7.3) min and (23.7±4.9) times], while the rate of one-time placement of disposable K-wire in the study group was significantly higher than that in the control group [84.2%(149/177) versus 32.2%(56/174)] ( P<0.05). There were no significant differences in Baumann angle, carrying angle, fracture healing time, or Flynn score of elbow joint function at the final follow-up between the 2 groups ( P>0.05). The incidence of complications in the study group (6.8%, 4/59) was significantly lower than that in the control group (20.7%, 12/58) ( P<0.05). Conclusions:Our self-designed guide device for Kirschner-wire placement is simple and convenient to use. In the surgery for paediatric fractures of supracondylar humerus, it can improve the rate of one-time placement of disposable K-wire, reduce intraoperative fluoroscopy, and decrease the incidence of complications.
