Abstract: Objective　To investigate the distribution and drug resistance characteristics of pathogenic bacteria in patients with neutropenic acute leukemia (AL) and bloodstream infections (BSI). Methods　The clinical data of 258 neutropenic acute leukemia patients with bloodstream infections, who admitted to Shengjing Hospital of China Medical University from January 2016 to December 2021, were collected and analyzed for pathogenic bacteria and drug resistance. Results A total of 268 strains of pathogenic bacteria were isolated from 258 patients, including 180 strains of gram-negative bacteria (67.16%), 61 strains of gram-positive bacteria (22.76%), and 27 strains of fungi (10.07%). Gram-negative bacteria were mainly Klebsiella pneumoniae (53/268, 19.78%), Escherichia coli (49/268, 18.28%) and Pseudomonas aeruginosa (41/268, 15.30%). Gram-positive bacteria were mainly coagulase negative Staphylococcus (31/268, 11.57%) and Staphylococcus aureus(17/268, 6.34%). The main fungi were Candida tropicalis (25/268, 9.33%). Escherichia coli (33/268, 12.31%) was the most common pathogen isolated from acute myeloid leukemia (AML), followed by Pseudomonas aeruginosa (25/268, 9.33%), coagulase-negative Staphylococcus (18/268, 6.72%) and Candida tropicalis (18/268, 6.72%). Klebsiella pneumoniae (35/268, 13.06%) was the most common pathogen isolated from acute lymphoblastic leukemia (ALL),followed by Pseudomonas aeruginosa (15/268, 5.60%) and Escherichia coli (14/268, 5.22%). The resistance of Gram-negative bacteria to piperacillin/tazobactam, cefoperazone/sulbactam, imipenem, meropenem, ertapenem, amikacin, cefoxitin, amoxicillin/clavulanic acid was low. Gram-positive bacteria were sensitive to linezolid and vancomycin. Candida was sensitive to flucytosine, amphotericin B and itraconazole. Conclusions　In patients with granulosa after AL chemotherapy combined with BSI, the pathogenic bacteria isolated from AML are diverse, and the pathogenic bacteria isolated from ALL are mainly gram-negative bacteria. Pathogenic bacteria have different degrees of drug resistance to commonly used antibacterial drugs, so it is important to strengthen the monitoring of the distribution of pathogenic bacteria and the change of drug resistance and rational use of antibacterial drugs to minimize the death of patients.

Objective To investigate the clinical characteristics, diagnosis and treatment of acute mesenteric venous thrombosis(MVT) in the elderly. Methods The clinical features, diagnosis, treatments and prognosis of 10 aged cases with acute MVT were retrospectively analyzed. Results The chief complaints of the 10 cases were different degrees of abdominal pain, which not paralleled with abdominal signs. The accompanying symptoms were nausea, vomiting and bloody stools and so on. All of these patients were misdiagnosised as pancreatitis, appendicitis or intestinal obstruction and so on. diagnosis of two cases was confirmed by ultrasound, 8 by CT. At the same time, 2 cases underwent angiography examination. Of the 8 cases who underwent operation, 5 cases were cured, 3 cases died (1 died of toxic shock and 2 died of multiple organ failure ). Two cases underwent conservative intervention thrombolysis. Conclusions It is essential to improve the knowledge of acute MVT,especially its intricate clinical characteristics, high rates of misdiagnosis and mortality. Early proper diagnosis is crucial. The main treatment is operation and conservative intervention thrombolysis can be performed in the patients whose bowel has not necrosed yet.

Objective To examine the effect of rapid infusion test guided by extravascular lung water index (EVLWI) on hemodynamics in critically ill patients at different states in order to guide volume resuscitation.Methods A prospective observation was conducted.Forty critically ill patients admitted to Department of Critical Care Medicine of Tianjin Third Central Hospital from June 2012 to April 2014 were enrolled.Based on the levels of EVLWI and pulmonary vascular permeability index (PVPI) and the cardiac function,the patients were divided into four groups:septic patients with normal EVLWI and PVPI (n =17),septic patients with increased EVLWI and PVPI (n =3),septic patients with increased EVLWI and normal PVPI (n =4),and coronary heart disease and heart failure patients with normal EVLWI and PVPI (n =16).The rapid infusion test was conducted in all patients using lactated Ringer solution 250 mL,followed by infusion of crystalloid with rate of 150 mL/h.The conditions of mechanical ventilation and vasoactive drugs were not changed during study.The changes in EVLWI,intrathoracic blood volume index (ITBVI),and cardiac index (CI) before capacity load,at immediate capacity load,and 15,45,105 minutes after load were determined by pulse indicator continuous cardiac output (PiCCO).On the base of volume status before and after the liquid infusion,the standard for the changes were:stroke volume (SV) increased by 12％-15％,central venous pressure (CVP) greater ≥ 2 mmHg (1 mmHg =0.133 kPa),CI ＞ 15％,and ITBVI change greater than 10％.Results There were no statistically significant differences in the observed indicators at the each time point before and after rapid infusion test among the four groups (all P ＞ 0.05).In septic patients with normal EVLWI and PVPI group,ITBVI was slightly increased by 5.4％-9.7％ from 15 minutes to 45 minutes after rapid infusion test.In coronary heart disease and heart failure patients with normal EVLWI and PVPI group,the EVLWI was increased by 11.9％,5.9％,and 14.7％ respectirely at 15,45,and 105 minutes,ITBVI was slightly increased by 6.4％ at 45 minutes,CI was increased by 29.5％ immediately after rapid infusion.In septic patients with increased EVLWI and PVPI group,CVP was increased by 8 mmHg immediately,EVLWI was increased significantly by 15.8％ at 45 minutes,ITBVI was slightly decreased by 10.0％ at 45 minutes,CI was increased by 24.7％ immediately,and increased by 17.0％ at 105 minutes,and PVPI was increased by 15.6％-28.1％ at 15-105 minutes after rapid infusion.In septic patients with increased EVLWI and normal PVPI group,CVP was increased by 1.5 mmHg at 15 minutes,EVLWI was increased immediately,which was increased by 17.4％,24.0％,and 31.4％ respectively at 15,45,and 105 minutes,ITBVI was increased by 13.9％ at 15 minutes,CI was increased by 16.1％ at 15 minutes after rapid fluid infusion.Conclusions Rapid fluid replacement in critically ill patients with crystalloid,regardless of whether the EVLWI was normal or increased,the short-term response was affected by the volume and cardiac function of patients.Different status of patients showed different volume effect curve:no significant changes in hemodynamic parameters were found in patients with normal EVLWI and volume parameters.In patients with potential cardiac dysfunction,CI and EVLWI increased significantly; regardless of PVPI increased or normal,EVLWI and CI were increased in patients with elevated EVLWI; two different changes could be found in the two types of pulmonary edema while ITBVI was increased.

ObjectiveTo evaluate the influence of continuous venovenous hemofiltration (CVVH) on measurement of transpulmonary thermodilution parameters.MethodsA prospective observational study was conducted. Fifty-six patients who received CVVH and hemodynamic monitoring at the same time admitted to the Department of Critical Care Medicine of Tianjin Third Central Hospital from July 2012 to July 2014 were enrolled. In all the patients, the dialysis catheter was inserted through the femoral vein, and transpulmonary thermodilution measurements were performed by pulse indicator continuous cardiac output (PiCCO) monitoring technology at the same time. Mean arterial pressure (MAP), central blood temperature, cardiac index (CI), global end-diastolic volume index (GEDVI), intrathoracic blood volume index (ITBVI) and extravascular lung water index (EVLWI) were measured before CVVH, immediately after CVVH, and 30 minutes after CVVH, respectively.Results In the 56 patients, there were 36 males and 20 females, (66±16) years of old, height of (172±6) cm, body weight of (68±10) kg. The acute physiology and chronic health evaluationⅡ (APACHEⅡ) scores was 26±6. After CVVH,the central blood temperature was gradually decreased, and blood temperature at 30 minutes after CVVH was significantly lower than that before CVVH (℃: 37.17±1.06 vs. 37.57±1.26,P< 0.01). There were no significant changes in MAP and EVLWI before and after CVVH, the MAP was (89±20), (86±16), (90±17) mmHg (1 mmHg = 0.133 kPa) at three time points respectively, and EVLWI was (9.4±3.2), (9.3±3.0), (9.4±2.9) mL/kg, respectively. After CVVH, CI, GEDVI and ITBVI showed a gradual downward tendency. Compared with those before CVVH, the decline of CI, GEDVI, and ITBVI immediately after CVVH was not statistically significant [CI (mL·s-1·m-2): 62.18±24.34 vs. 63.85±21.84, GEDVI (mL/m2): 705±103 vs. 727±100, ITBVI (mL/m2): 881±129 vs. 908±125, allP> 0.05]. CI, GEDVI, ITBVI at 30 minutes after CVVH were significantly decreased [CI (mL·s-1·m-2): 57.84±20.50 vs. 63.85±21.84, GEDVI (mL/m2):681±106 vs. 727±100, ITBVI (mL/m2): 851±133 vs. 908±125, allP< 0.05]. CVVH was associated with a decline of 6.01 mL·s-1·m-2 at 30 minutes after CVVH [95% confidence interval (95%CI) = -10.67 to -1.50,P = 0.011]. The declines of GEDVI and ITBVI were observed with 46 mL/m2 (95%CI = -81 to - 11,P = 0.014), 57 mL/m2 (95%CI =-101 to - 13,P = 0.014 ) respectively 30 minutes after CVVH.Conclusions CVVH had no significant effect on the transpulmonary thermodilution measurements of CI, GEDVI, ITBVI and EVLWI. Thirty minutes after the start of CVVH, CI, GEDVI and ITBVI was decreased significantly, but had no effect on EVLWI.

ObjectiveTo investigate the effect of out-patient training combined with family training under doctor's instructions on children with cerebral palsy (CP).Methods80 CP children were selected as treatment group and trained one to three months by therapists at out-patient department, then continually trained at family by parents who received doctor's instructions 30 min once every two or three months. 60 CP children in hospital were selected as control group. Rehabilitative effects of two groups were compared.ResultsIn the first and third month after training completed, movement growth of treatment group was not different from that of control group (P>0.05), but in the sixth month, was significant different from that of control group (P<0.05). The effect of treatment group was better than that of control group.ConclusionOut-patient training combined with family training under doctor's instructions can decrease treatment expenses, and is convenient and effective for CP children.
