ABSTRACT
Objective:To investigate the clinical effect of Infix combined with hollow screws for the treatment of pelvic injuries with pubic symphysis separation in middle-aged and elderly patients.Methods:Data of 8 middle-aged and elderly patients with pelvic injuries due to pubic symphysis separation undergone treatment from January 2017 to December 2020 were retrospectively analyzed.Results:The average operating time of 8 patients was (46.0±6.2)min(range: 40-62min); the average intraoperative blood loss was (32.0±5.6)ml(range: 25-50 ml); the average length of incisions at the iliac screw was(2.6±0.4)cm(range: 2.0-3.5 cm); the average length of incisions at the hollow screw was (1.1±0.3)cm(range: 0.8-1.5 cm); and the average times of fluoroscopy were (36.0±6.0)times(range: 28-52 times). Postoperative X-ray and CT examinations showed that the reduction of the pubic symphysis was good, the inserted iliac screws and cannulated screws were positioned accurately, and the incision healed well.Based on Matta's criteria, postoperative radiological outcomes were evaluated, with 7 cases rated as excellent and 1 as good, giving an excellent to good rate of 100%(8/8). The average followed up time for all 8 patients was (15.0±4.2)months(range: 6-24 months). Pelvic X-ray and CT examinations at the last follow-up showed that the fractures healed well and the pubic symphysis reduction did not fail.Infix and cannulated screws in the pubic symphysis were removed 10-12 weeks after surgery[average: (10.5±0.5)weeks]. According to the Majeed Pelvic Score, 5 cases were rated as excellent, 2 cases as good and 1 as fair, with an excellent to good rate of 87.5%(7/8). One patient had symptoms related to the lateral femoral cutaneous nerve that disappeared after 3 months.One patient developed deep venous thrombosis after surgery, and the filter was placed and removed 10 weeks later.Conclusions:Using Infix plus cannulated screws for the treatment of pelvic injuries in middle-aged and elderly patients with pubic symphysis separation has the advantages of limited trauma and intraoperative blood loss, good fixation and few complications.
ABSTRACT
Objective To analyze the serum levels of medium-and long-chain free fatty acids (FFAs)in patients with hyperlipidemic non-alcoholic fatty liver disease (NAFLD) in order to shed some light on prevention and treatment of NAFLD.Methods The clinical data of 125 patients with high triglyceride (TG)levels who were treated in Hebei General Hospital from January 2011 to May 2011 were analyzed in this study.They were further divided into HF group (n =64) and H group (n =61) based on the presence of NAFLD or not.In addition,63 healthy individuals were recruited from the Central Hospital of Handan during the same period as the control group (N group).Serum medium-and long-chain FFAs were detected by gas chromatography.The body mass index (BMI),abdominal circumference,blood pressure,fasting blood glucose (FBG),and serum lipids including TG,total cholesterol (TC),high-density lipoprotein cholesterol (HDL-C),and low-density lipoprotein cholesterol (LDL-C) were measured.Results Compared with the N group,the H group had significantly higher BMI [(25.24 ± 1.41) kg/m2 vs.(24.32 ± 1.12) kg/m2,P =0.004],abdominal circumference [(84.72 ± 1.34) cm vs.(77.33 ±0.89) cm,P =0.010],and diastolic blood pressure [(77.35±1.21) mmHgvs.(75.21 ±1.61) mmHg,P=0.014]; also,the serum TG [(2.86±0.55) mmol/Lvs.(0.93±0.27) mmol/L,P=0.000] andTC levels [(4.56±0.66) mmol/Lvs.(4.36±0.47) mmol/L,P=0.000],serum myristic acid (C14∶0) [(0.49±0.04)％ vs.(0.36±0.01)％,P=0.011],palmitic acid (C16 ∶ 0) [(18.36 ± 0.47) ％ vs.(15.97 ± 0.30) ％,P =0.000],palmitoleic acid (C16∶ 1) [(1.00±0.12)％ vs.(0.58±0.02)％,P=0.001],and oleic acid (C18 ∶ 1) [(18.20±0.70) ％ vs.(12.23 ± 0.37) ％,P =0.000] all significantly increased,while stearic acid (C18 ∶ 0) [(7.52 ±0.22)％ vs.(8.15 ±0.28)％,P=0.012],eicosadienoic acid (C20 ∶ 2) [(0.61 ±0.07)％ vs.(1.03 ±0.17) ％,P =0.000],eicosatrienoic acid (C20 ∶ 3) [(1.77 ± 0.15) ％ vs.(2.49 ± 0.18) ％,P =0.002],and docosahexenoic acid (C22 ∶ 6) [(1.44 ± 0.08) ％ vs.(1.67 ± 0.09) ％,P =0.014] significantly decreased.Compared with the H group,the HF group had significantly higher weight [(85.76 ± 3.10) kg vs.(71.45 ±2.88) kg,P =0.003],abdominal circumference [(96.30 ±2.05) cm vs.(84.72 ± 1.34) cm,P=0.000],systolic blood pressure [(117.12 ±1.15) mmHg vs.(113.23 ±1.25) mmHg,P=0.009],and diastolic blood pressure [(79.54 ± 1.42) mmHg vs.(77.35 ± 1.21) mmHg,P =0.016],whereas the sreum FGB,TG,TC,HDL-C,and LDL-C showed no significant differentces; serum palmitic acid (C16 ∶ 0)[(19.54 ± 0.30) ％ vs.(18.36 ± 0.47) ％,P =0.000] also significantly increased.The serum level of eicosadienoic acid (C20 ∶ 2) in HF group was between that in N group and H group [(0.78 ± 0.09) ％ vs.(1.03 ±0.17)％,(0.78±0.09)％ vs.(0.61 ±0.07)％,both P=0.000].Conclusions The increased serum level of palmitic acid may be a risk factor for NAFLD.Reducing saturated fatty acids and increasing unsaturated acids in diets may be helpful for preventing NAFLD.
