Objective To investigate the autonomic modulation and influence during myocardial ischemia based on analysis on heart rate dynamics with heart rate variability(HRV). Methods From 13 free download ECG records in long-term ST-T(LTST)database, 193 ischemia episodes were extracted for analysis, and 5 min intervals before and after each selected isehemia episode were selected as control ones. Using symbolic dynamic analysis method, the indexes during different stages were calculated. The repeated measurement analysis of variance was introduced for statistic test. And the distribution of autonomic reflex mode to isehemia duration was analyzed by linear fitting. Results Symbolic analysis detected an increase in the percentage of non-varlable patterns (0 V%) and a decrease in the percentage of very variable patterns(2 UV%), indicating a more sympathetic predominance compared with the baseline. But the trend of the shift in autonomic balance towards sympathetic predominance reduced with the extension of ischemic duration, suggesting a possible protection for heart. Conclusion Symbolic dynamic analysis is capable of identifying changes in autonomic modulation and seems appropriate for elucidating the neural pathophysiological mechanisms occurring in myocardial ischemic episodes.

Commensal microorganisms that colonize barrier surfaces of all multicellular organisms exist in harmony with their hosts and have an important effect on both immune and non-immune functions of their hosts. Numerous researches have shown that gastrointestinal microbiota being one of the most important commensal microorganisms plays a critical role in the occurrence, development and treatment of cancer. As-signing causal roles in cancer to specific microbes and microbiotas, unraveling host-microbiota interactions with environmental factors in carcinogenesis, and applying such knowledge to cancer diagnosis and treatment are areas of intensive interest. This review considers how microbes and the microbiota may amplify or miti-gate carcinogenesis, responsiveness to cancer therapeutics, and cancer-associated complications.

Objective:To evaluate the effect of separating drug sales from medical services on hospital revenue and medical services in the county-level public hospitals of Guangxi. Methods:The controlled before and after study design was employed. 2009 to 2012 was the pre-intervention period;2013 was the intervention period. Pilot people’s hospitals were included in the intervention group;non-pilot people’s hospitals were included in the control group. Da-ta came from hospitals and new rural cooperative medical statistics from 2009 to 2013 and the Guangxi Statistical Yearbook from 2010 to 2014. The analysis method of difference-in-differences based regression was employed. Re-sults:Separating drug sales from medical services included cancelling medicine markups, increasing price of inspec-tion and nursing services, reducing price of large equipment inspection services and increasing financial assistance. In terms of hospital revenue, compared with non-pilot hospitals, for pilot hospitals, the reform reduced medicine rev-enues by 3. 326 million yuan and increased medical revenue by 10. 75 million yuan. There was no significant change in financial assistance. In terms of medical expenses, compared with non-pilot hospitals, the reform reduced per-visit outpatient drug expenses in pilot hospitals by 3. 51 yuan, increased per-visit outpatient inspection fees by 2. 23 yuan, reduced per-visit inpatient drug expenses by 133. 5 yuan, increased per-visit inpatient inspection fees by 62. 01 yuan, and increased per-visit inpatient nursing fees by 69. 72 yuan. There were no significant change in outpatient and inpa-tient visits, length of stay, outpatient expenses per-visit and inpatient expenses per-visit. Conclusion:County hospi-tals can offset losses due to cancelling medicine markups by medical service pricing adjustment in inpatient departments;in outpatient departments, they can offset losses due to cancelling medicine markups by both medical service pricing ad-justments and medical service utilization adjustments beyond policy adjustments. The reform did not reduce the operating revenue of pilot hospitals or the medical expenses per visit. The reform had little effect on hospital and doctor incentives.

Objective To evaluate the plasma amino acid level alteration and determine amino acid loss in patients with abdominal inflammation and acute renal failure during continuous veno-venous hemofiltration (CVVH). Methods Ten patients with abdominal infection and acute renal failure were admitted to the Nanjing General Hospital of Nanjing Military Command of PLA from September 2008 to September 2009. CVVH was performed with AV600S polysulfone hemofilter for 24 hours. Samples of plasma amino acid were obtained before,at 12 and 24 hours after the beginning of CVVH. High pressure liquid chromatography was used to detect amino acid concentrations in plasma and replacement fluid. All data were analyzed using t test or Wilcoxon rank sum test. Results Of the ten patients, three died of septic shock and three died of multi-organ dysfunction syndrome.The level of plasma amino acids decreased significantly after CVVH, and the levels of histidine, isoleucine, cysteine and glutamine decreased from (22.1 ±10.3), (20.0 ±7.6), (10.3±4.7), (122.3 ±72.2)μmol/L to (5.6 ±3.4), ( 6.4 ± 2.5 ), ( 2.9 ± 2.4 ), (42.5 ± 33.6) μ mol/L. The total plasma amino acid levels significantly reduced by 52% at 12 hours after the beginning of CVVH and by 59% at 24 hours after the beginning of CVVH.The mean amino acid loss was (9631± 1089)mg/d. The mean losses of essential and non-essential amino acids were ( 5072 ± 618 ) mg/d and ( 3747 ± 654 ) mg/d, respectively, with a significant difference ( t = 4. 52,P ＜0.05 ). There was a positive correlation between individual amino acid loss and the plasma concentrations of respective amino acids at 12 hours after the beginning of CVVH ( r = 0. 68, P ＜ 0.05 ). Conclusions Plasma amino acid would be cleared through hemofilter during CVVH in patients with abdominal inflammation and acuterenal failure. As a result, it is necessary to take account of the ultrafiltrate amino acid loss when setting nutritional schedule, especially increasing the non-essential amino acid content of total parenteral nutrition.
