Objective To explore the feasibility and superiority of the simple controllable aerocyst pressurization wrapped-up bondage for battlefield first aid in the future high tech local war. Methods The disposable infusion bag is wrapped up in the bottom of the sling in stead of partial surgical dressing. Sphygmomanometer, pressure gauge and heparin hat are connected. Inflate and pressurize the sphygmomanometer and keep the pressure between 3kPa and 5kPa. Results The structure of this bandage is simple and can be operated easily. The pressure is controlled nimblely and conveniently. Except for the accurate effect, it is versatile and inexpensive. In addition, it can be employed in the bone fracture.

Objective To investigate the effects of enteral immunonutrition supplemented with omega-3 polyunsaturated fatty acid (ω-3 PUFA) on the incidences and severity of ventilator associated pneumonia com- plications, inflammatory response, and the prognosis in patients with severe traumatic brain injury (sTBI) un-dergoing ventilator therapy. Methods From January 2015 to June 2017, 64 patients of sTBI were selected and randomly divided into experimental group (ω-3 PUFA, n=32) and control group (n=32). White blood cells (WBC) and the proportion of neutrophils (N%) were evaluated by cell analyzer. Meanwhile, the serum levels of C-reactive protein (CRP) and procalcitonin (PCT) were tested with enzyme linked immunosorbent assay. After 14-days treatment, the Glasgow coma scale (GCS) score, APACHE Ⅱ score, clinical pulmonary infec-tion score (CPIS), pulmonary function and prognoses were also compared between the two groups. Results As compared with the control group, the experimental group had lower incidences of ventilator associated pneumonia (66% vs. 56%, P=0. 048), reduced degree of lung infection and lower CPIS (8. 25±0. 60 vs. 7. 47±0. 53); higher lung function indexes [FVC: (2. 89±0. 19) L vs. (3. 46±0. 22) L, P=0. 010;FEV1: (2. 35±0. 16) L vs. (2. 84±0. 24) L, P=0. 040; FEV1/FVC %: (49. 11±3. 34)% vs. (56. 00± 2. 64)%, P=0. 038) ]; lower serum levels of inflammatory responses [WBC: (11. 83±0. 74) ×109/L vs. (9. 51±0. 90) ×109/L, P=0. 029; N%: (79. 11±1. 51)% vs. (72. 71±1. 16)%, P=0. 041; CRP:(85. 15±8. 42) mg/L vs. (63. 96±5. 72) mg/L, P=0. 001; PCT: (6. 43±0. 47) μg/L vs. (4. 83±0. 39) μg/L, P=0. 013] 14 days after enteral immunonutrition supplemented with ω-3 PUFA. As compared with the control group, the experimental group received better prognosis with GCS scores increasing ( 8. 69 ± 0. 41 vs. 9. 52±0. 59, P=0. 038), APACHE Ⅱ scores decreasing (14. 74±1. 01 vs. 12. 68±0. 89, P=0. 049), the time of mechanical ventilation [ (13. 23±1. 17) d vs. (10. 88±1. 24) d, P=0. 024] and the hospitalization days [ (23. 29±2. 45) d vs. (18. 42±1. 96) d, P=0. 012] reduced on the 14th day, mechanical ventilation withdraw rate within 14 days increasing [24/32 (75%) vs. 27/32 (84%), P=0. 030] on the 14th day. Conclusion Enteral immunonutrition supplemented with ω-3 PUFA can effectively reduce the incidence of ventilator associated pneumonia, alleviate the degree of infection and the inflammatory response in patients with sTBI undergoing ventilator therapy possibly improving condition and prognosis, which is worthy of being widely used.

Objective: To analyze the hematological characteristics of a patient with Hb Ottawa in conjunction with β-thalassemia. Methods: Peripheral blood samples from the proband and her parents were collected and subjected to red blood cell analysis and hemoglobin electrophoresis. Genotypes of α- and β-globin genes were also analyzed. Results: The proband and her mother were both heterozygotes for Hb Ottawa and β-thalassemia variant IVS II-654, and presented with typical β-thalassemia trait featuring hypochromic microcytic anemia. An abnormal hemoglobin band was detected upon electrophoresis. Conclusion Co-existence of Hb Ottawa and β-thalassemia may not aggravate the phenotype.

Objective:To explore the predictive factors of renal replacement therapy (RRT) in extracorporeal membrane oxygenation (ECMO) patients.Methods:The clinical data of 68 ECMO patients treated at Emergence Department of Jiangsu Provincial Hospital from January 2015 to December 2018 were retrospectively analyzed. Vasoactive-inotropic score (VIS) was used to assess the usage of vasoactive-inotropic drugs on day 1, 2 and 3 of ECMO (24 h VIS, 48 h VIS, and 72 h VIS). According to received RRT or not, patients were divided into the RRT group and non-RRT group. Age, gender, weight, VIS, presence of cardiac arrest before ECMO, ECMO mode, and ECMO treatment time were compared. Logistic regression analysis was used to identify predictive factors for RRT in ECMO patients.Results:Of the enrolled patients, 73.5% of ECMO patients received RRT. The mean age, 24 h VIS, ECMO failure and mortality of the RRT group were significantly higher than those of the non-RRT group ( P <0.05). The use of RRT was 87.8% in elderly ECMO patients (> cutoff age of 38.5 years). According to the cutoff value of 24 h VIS (33.75), ECMO patients were divided into the high VIS group and low VIS group. The rates of RRT and mortality were both exceeded 90% in the high VIS group, which was significantly higher than that of the low VIS group ( P <0.05). Logistic regression analysis showed that age ( OR=1.223) and 24 h VIS ( OR=1.033) were predictive factors of RRT in ECMO patients ( P <0.05). Conclusions:Age and 24 h VIS show the predictive value for RRT in ECMO patients.
