ObjectiveTo explore the application of different digestive system management strategies in the perioperative period of thoracolumbar fracture.MethodsThe clinical data of the patients with thoracolumbar fractures and pedicle screw fixation in Affiliated Hospital of Southwest Medical University from January 2016 to January 2018 were retrospectively analyzed. According to different perioperative management strategies of the digestive system, they were divided into two groups. Patients with careful management strategy were included in the observation group, and patients with routine management were included in the control group. The baseline conditions, the abnormalities of digestive tract function at admission and before and after surgery, the postoperative first feeding time, exhaust time, defecation time, the incidence of other postoperative complications except digestive tract complication, length of stay and patient satisfaction were compared between the two groups. At 6 months after surgery, the fracture healing, loosening or fracture of internal plants were compared between the two groups.ResultA total of 121 patients were included in the study, including 67 cases in the observation group and 54 cases in the control group. There was no significant differences in the baseline conditions between the two groups (P>0.05). There were no significant differences between the two groups in the incidences of digestive system dysfunction at admission (P>0.05). The incidences of digestive system dysfunction in the observation group before and after surgery were lower than those in the control group (29.9% vs. 53.7%, P<0.05; 35.8% vs. 61.1%, P<0.05). The first eating time [(3.7±1.1) vs. (6.7±2.6) h], exhaust time [(7.8±2.3) vs. (13.6±4.2) h], defecation time [(26.7±8.1) vs. (40.9±11.2) h] and length of stay [(6.5±2.4) vs. (9.0±2.7) d] in the observation group were shorter than those in the control group (P<0.005), and the patients’ satisfaction was better than that of the control group (8.3±1.1 vs. 7.6±1.3; t=−3.208, P=0.002). There was no statistically significant difference in the incidence of postoperative complications except digestive tract complication, and the fracture healing rate, the incidence of nail-rod breakage at6 months after surgery between the two groups (P>0.05). No internal plant loosening was found in the two groups of patients within 6 months after surgery.ConclusionThe application of the careful digestive system management strategy in patients with thoracolumbar fractures can help reduce the incidence of perioperative gastrointestinal dysfunction, promote the recovery of perioperative gastrointestinal function, shorten the length of hospital stay, and improve patient satisfaction.
With chronic kidney disease becoming a public health problem in the world, dialysis treatment model has also become the focus of attention from all walks of life. Sustained low-efficiency dialysis, which adopts the mode of low blood flow and low dialysis volume, is a kind of hybrid renal replacement therapy combining continuous renal replacement therapy and intermittent hemodialysis. It has unique advantages in the treatment of patients with acute and severe renal injury, as well as the dialysis duration, patient activity range and cost. It is the most widely used hybrid renal replacement therapy too. This review summarizes the clinical application and nursing points of sustained low-efficiency dialysis to provide guidance for clinical practice.

ObjectiveTo evaluate the safety and efficacy of local sodium citrate anticoagulation for routine hemodialysis in high-risk patients with hemorrhage.MethodsA total of 150 patients who were admitted to West China Hospital from October 2018 to March 2019 for routine hemodialysis treatment with high-risk bleeding were selected as study objects. The patients were divided into without heparin anticoagulation group (group A) and with 4% sodium citrate anticoagulation group (group B) by random number table method, with 75 cases in each group. Biochemical indicators, serum calcium ion concentration, local anticoagulation safety index of citrate and dialysis adequacy index, blood coagulation in dialyzer and tube during dialysis wre observed in the two groups.ResultsThe coagulation events in group B were significantly lower than those in group A (Z=–4.889, P<0.001), and the urea clearance index in group B was higher than that in group A [(1.26±0.12) vs. (0.73±0.13) L/(min·1.73 m2); t=22.418, P<0.05]. There was a significant difference in the changes of urea nitrogen [(3.53±1.05) vs.(3.12±1.11) mmol/L; t=2.323, P=0.021] 24 hours after dialysis; other indicators showed no statistically significant difference (P>0.05). After the filter, serum calcium ion concentrations in group B at different time points were lower than those in group A [2 hours: (0.52±0.07) vs. (0.64±0.08) mmol/L; 4 hours: (0.56±0.09) vs.(0.63±0.09) mmol/L; t=5.198, 0.525, P<0.001], and the coagulation time was higher in group B than that in group A [2 hours: (172.56±14.78) vs. (151.45±19.81) s; 4 hours: (168.45±16.48) vs. (152.88±16.54) s; t=7.396, 5.775, P<0.001]. None of the patients had dialysis-related adverse events.ConclusionFour percent sodium citrate is effective and safe in anticoagulation therapy for hemodialysis patients, and it can reduce the risk of coagulation in dialyzer and ensure the adequacy of maintenance hemodialysis.
Abstract:Objective To observe the expression of calcium-dependent proline-rich tyrosine kinase-2（Pyk2） in myocardium of rheumatic heart disease, the relationship between its role and cardiac fibrosis and clinical significance. Methods The blue myocardium collagen stain were analysed after Masson staining in 30 patients with rheumatic heart disease （RHD group） and 6 normal myocardium specimens （control group）. The contents of hyaluronic acid （HA）, laminin（LN） and type IV collagen（IV-C） were detected by radio-immunity method,and the expressions of Pyk2 protein and messenger ribonucleic acid（mRNA） were explored by immunohistochemistry methods and reverse transcriptase polymerase chain reaction （RT PCR）,then the correlations of these results were statistically analyzed. Results The contents of HA,LN and IV C in RHDgroup increased compared to control group（174.95±76.14μg/L vs. 70.06±15.63μg/L, 153. 86 ± 20. 72μg/L vs. 90.01±14. 11μg/L, 95. 26±7.66μg/L vs. 63. 21±10.62μg/L; P= 0.003, 0. 013, 0. 035）. The Pyk2 absorption and the ratio of Pyk2 mRNA/glyceraldehyde phosphate dehydrogenase （GAPDH） in RHD group were significantly higher than those in control group （0. 325 ± 0. 032 vs. 0.106±0.013, 0.870±0.085 vs. 0.573±0.042; P=0.048, 0.006）.There were positive correlativity between the expression of Pyk2 protein and HA, LN and IV-C （r=0. 611, 0. 743, 0. 829, P〈0. 01）, there were positive correlativity between the expression of Pyk2 mRNA and LN, IV-C （r=0. 794, 0. 766, P〈0.05）.
