The largest sugarcane-growing area in the United States is in South Florida. An estimated 7 million tons of dry sugarcane leafy biomass is removed from the fields before harvest by burning the leaves off the sugarcane stalks. Preharvest sugarcane leaf foliage burning is a major source of airborne particulate matter (PM), polycyclic aromatic hydrocarbons (PAHs), biogenic trace elements such as K, volatile hydrocarbons and other pollutants. In one harvesting period, approximately 22 million tons of C02, a greenhouse gas, is released, 7 million tons from leaf foliage preharvest burning alone and 15 million tons from burning sugarcane bagasse in the sugar mills for power generation. In this study, PMio was collected from Belle Glade, close to the sugarcane-growing area, and from Delray Beach, an urbanized area along the East Coast of Florida. The PM samples were analyzed for trace elements and close to organic compounds. To elucidate the importance of preharvest sugarcane biomass smoke emissions on air quality, 39 trace elements, 18 PAHs, and levoglucosan were selected to apportion ambient PM constituents. Al, Ca and to a great extend also Mg are the major soil-related trace elements and key markers for fugitive soil dust emissions. Similarly, sea salt aerosol blown from the Atlantic Ocean into Florida added appreciably to PMio trace elements concentration, especially Na and Cl. Approximately half of the sea salt aerosol (PMjo -portion) by mass is removed from the atmosphere during the transport of ocean air from Delray Beach to Belle Glade. Ambient acid displacement reactions caused a substantial portion of the Cl (30%) to be liberated from the sea salt aerosol to the atmosphere during transport as gaseous HC1. The PAH concentrations at Belle Glade were high when the biomass combustion markers levoglucosan and I< also showed the highest concentrations. This indicates that during the sugarcane harvest season, when leaf foliage is burned off just before harvest, most of

COMPARATIVE OBSERVATION ON EFFECT OF ELECTRIC ACUPUNCTURE OF NEIGUAN (P 6) AT CHEN TIME versus XU TIME ON LEFT VENTRICULAR FUNCTION IN PATIENTS WITH CORONARY HEART DISEASE

引用

Journal of Traditional Chinese Medicine 1994年第4期14卷 262-265页

作者：李磊陈汉平溪永江王绪业韩桂庭周玉良杨登平赵文强冯志强焦炳芬谢萍朱艾春尹素梅李玲 Shanghai TCM College Shanghai 200032 Huaibei Municipal People's Hospital Anhui Province 235154

Paired experimental design was adopted in this experiment for comparative observation on effect of electric acupuncture (EA) of Neiguan (P 6) at Chen Time (7 a.m. to 9 a.m.) versus Xu Time (7 p.m. to 9 a.m.) on left ventricular function in patients with coronary heart dis-ease (CHD). The results show that EA performed at Chen Time could improve the left ventricular function of CHD patients as indicated by shortening of PEPI and decrease of PEPI/LVETI ratio; on the contrary, EA performed at Xu Time prolonged PEPI and raised PEPI/LVETI ratio in CHD patients, suggesting impairment of left ventricular function.

A randomized controlled clinical trial on piperacillin/tazobactam versus ticarcillin/clavulanic acid for the treatment of bacterial infections

引用

Chinese Medical Journal 1998年第11期 80-84页

作者：侯芳李家泰高磊陈扬

Objective To compare the efficacy and safety of two β lactam β lactamase inhibitor combinations, piperacillin/tazobactam and ticarcillin/clavulanic acid in the treatment of bacterial infections. Methods A randomized, open labeled, controlled study was conducted for the treatment of 124 hospitalized patients with lower respiratory tract infection and urinary tract infections. Sixty three patients received piperacillin (4 g)/tazobactam (500 mg) every 8 hours by intravenous infusion and 61 patients received ticarcillin (3 g)/clavulanic acid (200 mg) every 8 hours by intravenous infusion. The duration of treatment was 7-14 days in both groups. Results Sixty three of 79 cases who received piperacillin/tazobactam and 61 of 84 cases who received ticarcillin/clavulanic acid were assessable for clinical efficacy. The overall efficacy rates were 90.5% for the piperacillin/tazobactam group and 88.5% for the ticarcillin/clavulanic acid group, whereas the bacterial eradication rates were 90.2% and 92.0%, respectively. 78 (77.2%) of 101 strains isolated from patients produced β lactamases. The adverse reaction was evaluated in 65 cases of piperacillin/tazobactam group and 62 cases of ticarcillin/clavulanic acid group. The adverse drug reaction rates were 7.69% (5/65) and 8.06% (5/62), respectively. Conclusions Piperacillin/tazobactam and ticarcillin/clavulanic acid were effective and safe for the treatment of lower respiratory tract infections and urinary tract infections caused by β lactamase producing strains. The results showed that there was no statistical difference between these two groups (P>0.05).

Dexamethasone versus Prednisone in Childhood Acute Lymphoblastic Leukemia Treatment: Results of the Indonesian Randomized Trial

引用

Journal of Cancer Therapy 2017年第8期8卷 735-750页

作者： Pudjo H. Widjajanto Eddy Supriyadi Ignatius Purwanto Jacqueline Cloos Peter M. vdVen Sutaryo Anjo JP. Veerman Pediatric Hematology and Oncology Division Department of Pediatrics Sardjito Hospital Medical Faculty Universitas Gadjah Mada Yogyakarta Indonesia Pediatric Oncology/Hematology Division Department of Pediatrics VU University Medical Center Amsterdam The Netherlands Department of Hematology VU University Medical Center Amsterdam The Netherlands Department of Epidemiology and Biostatistics VU University Medical Center Amsterdam The Netherlands

Background: Randomized trials report that, compared to prednisone, dexamethasone has reduced CNS relapse and improved event-free survival (EFS), despite a trend toward a higher risk for induction death. Because toxic death is a specific problem in the Indonesian setting, this study compares the outcome of dexamethasone versus prednisone. Methods: In the period 2006 - 2011, 196 patients with childhood acute lymphoblastic leukemia (ALL) treated on the Indonesia-ALL-2006 protocol [first standard risk (SR) and later high risk (HR) patients] were randomized to receive dexamethasone or prednisone as steroid. Patients in the dexamethasone arm (n = 102: 68 SR, 34 HR) received dexamethasone 4 mg/m2/day (SR) or 6 mg/m2/day (HR), while the prednisone arm (n = 94: 66 SR, 28 HR) received prednisone 40 mg/m2/day (SR and HR). Results: Patients in the dexamethasone arm showed no significant difference compared to the prednisone arm in abandonment rate (24.5% vs. 25.5%, P = 0.91), death rate (17.7% vs. 14.9%, P = 0.54), or leukemic events (13.7 vs. 11.7%, P = 0.59). After stratification for risk group, a trend towards a higher death rate was found in the dexamethasone arm of SR patients (16.2 vs. 6.1%, P = 0.06). The 3-year survival for EFS in SR and HR patients for dexamethasone versus prednisone was 31.5% ± 6.6% vs. 41.5% ± 5.9% (P = 0.51), for leukemia-free survival (LFS) it was 63.7% ± 9.3% vs. 74.5% ± 7.6% (P = 0.47), and for overall survival (OS) it was 49.5% ± 7.7% vs. 69.3% ± 6.1% (P = 0.09). Conclusions: In our setting, a trend toward higher induction deaths was observed in the dexamethasone arm of SR patients and the 3-year EFS;LFS and OS rates were lower in the dexamethasone group;however, these differences were not significant.

Circular versus Linear versus Hand-Sewn Gastrojejunostomy in Roux-en-Y-Gastric Bypass: Data Analysis from a Quality Assurance Study of the Surgical Treatment of Obesity in Germany

引用

Surgical Science 2014年第7期5卷 280-289页

作者： Christine Stroh Grigorji Nesterov Rudolf Weiner Frank Benedix Christian Knoll Matthias Pross Thomas Manger DRK Hospital Berlin Koepenick Germany Helios Hospital Bad Saarow Germany Sachsenhausen Hospital Frankfurt/Main Germany SRH Municipal Hospital Gera Germany StatConsult Magdeburg Germany University Hospital Magdeburg Germany

Background: Since January 12005, the outcomes of bariatric surgeries have been recorded in Germany. All data are registered prospectively in cooperation with the Institute of Quality Assurance in Surgery at Otto-von-Guericke University Magdeburg.?Methods: Data are collected in an online data bank. Data collection began in 2005 for the results of Roux-en-Y Gastric Bypass (RYGB). In addition to primary bariatric operations, data regarding the complications and the amelioration of comorbidities have been analyzed. Participation in the quality assurance study is required for all certified centers in Germany.?Results: Roux-en-Y Gastric Bypass is the most popular bariatric operation in Germany. There were 5115 operations performed from 2005 to 2010. A circular anastomosis was performed in 1587 patients, and a linear anastomosis was performed in 2734 patients. In 783 patients the hand-sewn technique was used. The leakage rate for the linear technique is 1.6%, and the leakage rate is 1.2% for circular anastomosis and 1.4% for hand-sewn technique. The overall postoperative complication rate was significantly higher using the circular technique than using the linear or hand-sewn approach.?Conclusion: RYGB is a popular procedure in Germany. The complication rate has decreased since 2005. A comparison of hand sewn versus linear and versus circular anastomosis indicated a higher complication rate in circular gastrojejunal junctions.
