Objective: To explore the effect of ulinastatin on anti-inflammation and pulmonary function protection with its mechanism for infants at cardiopulmonary bypass surgery. Methods: A total of 38 infants with ventricular septal defect undergoing cardiac operation were randomly divided into 2 groups. Ulinastatin group, the patients received uliastatin 20 000 U/kg,n=20 and Control group, the patients received the same volume of normal saline,n=18. The serum levels of TNF-α, IL-2, IL-l0 were examined at 4 time points: 5 min before skin incision (T1), immediate opening of aorta (T2), 4 hours after operation (T3) and 24 hours after operation (T4). The expressions of CD4+CD45+ T cells and CD4+Foxp3+ T cells were measured at T4. The respiratory index and oxygenation index at 4 time points were compared between 2 groups. Results: Compared with Control group, Ulinastatin group had the lower levels of TNF-α, IL-2 and higher level of IL-l0 at T2, T3, T4; Ulinastatin group also had the higher oxygenation index and lower respiratory index at T2, T3, T4, allP<0.05. Ulinastatin group had less expression of CD4+CD45+ T cells (35.98 ± 3.67)% than Control group (41.94 ± 4.56)% , and more expression of CD4+Foxp3+ T cells (19.65 ± 3.45)% than Control group (6.45 ± 1.47)%,P<0.05-P<0.01. Conclusion: Ulinastatin may improve the differentiation from CD4+CD45+ T cell to Foxp3+CD4+ T cell, down regulating inlfammatory response and protecting pulmonary function for infants at cardiopulmonary bypass surgery.

Fluid therapy is a crucial treatment for patients with extensive burn, which affects patients′prognosis directly. Accurate urine output measurement plays an irreplaceable role in guiding fluid resuscitation in clinic. As one of the best indexes in traditional burn resuscitation, urine output comprehensively reflects systemic circulation. However, it doesn′t fully reflect all the specific chapters of microcirculation and systemic circulation and deficient cellular oxygen metabolism exactly. We need to use urine output combined with other shock parameters to ensure adequate fluid replacement. Currently, the most common way of urine output monitoring is manual measurement. The article reviews the application of urine output monitoring in guiding fluid resuscitation of burn shock.

Objective To investigate the problems during using, standard and quality management of the POCT glucose meters in hospital, to analyze the solutions, and to provide reference data for improving the test level of POCT in hospital.Methods The amount, brand and application of portable glucose meters in the hospital were obtained by 3 rounds of surveillance from May to July in 2013.All of those glucose meters were taken part in external quality assessment of Clinical Laboratory Center of National Health and Family Planning Commission.The test results of those glucose meters were compared with that of automatic biochemical analyzer, the comparison results were then analyzed.Results The POCT glucose meters possessed 5 brands in our hospital, and the amount and type of glucose meters in some clinical departments were often changed.When 4 brands which were detected as quality control samples by ministry of health, the accuracy of detection results of 3 concentration of brand Ⅲ were substandard, the CV% of two levels were 11.9%and 10.1%respectively, the remaining 3 brands were in line with the requirements.The qualified percentages of 3 times of comparison were 85.0%, 92.0%and 97.4%.Conclusions The hospital should select the brand of portable glucose meters reasonably, correct use of glucose meters, and it is very necessary to build indoor and interstitial quality evaluation system, at the same time, suggesting the hospital to establish the POCT quality management team, to carry out the instrument comparison periodically, so to guarantee the accurate, reliable results of POCT in hospital.

Objective:To explore the death risk factors of extremely severe burn patients, establish a death risk nomogram predicting model, and investigate the predictive value for death risk of extremely severe burn patients.Methods:The medical records of 231 extremely severe burn patients (190 males and 41 females, aged 18-60 years) who were admitted to the Institute of Burn Research of the First Affiliated Hospital of Army Medical University from January 2010 to October 2018 and met the inclusion criteria were analyzed retrospectively. According to the final outcome, the patients were divided into survival group of 173 patients and death group of 58 patients. The sex, age, severity of inhalation injury, total burn area, full-thickness burn area, burn index, rehydration coefficient and urine volume coefficient of the first and second 24 h after injury, the first base excess, shock index, and hematocrit (HCT) after admission, whether to have pre-hospital fluid infusion, use of ventilator, and use of continuous renal replacement therapy (CRRT), and abbreviated burn severity index (ABSI ) and Baux score on admission of patients in the two groups were recorded or calculated. According to the use of ventilator, the patients were divided into with ventilator group of 131 patients and without ventilator group of 100 patients, and the death, total burn surface area, burn index, incidence and severity of inhalation injury were recorded. According to the use of CRRT, the patients were divided into with CRRT group of 59 patients and without CRRT group of 172 patients, and the death, total burn surface area, and burn index were recorded. Data were statistically analyzed with t test, chi-square test, and Mann-Whitney U test to screen the death related factors of patients. The indexes with statistically significant differences between survival group and death group were included in the multivariate logistic regression analysis to screen the independent death risk factors of patients, and the death risk nomogram predicting model was constructed based on the results.The Bootstrap method was used to validate the death risk nomogram predicting model internally. The predictive value of the nomogram model for predicting death risk of patients was detected by drawing calibration graph and calculating concordance index, and the death risk scores of 231 patients were acquired according to the death risk nomogram model. The receiver′s operating characteristic (ROC) curve was drawn, and the optimal threshold and the sensitivity and specificity of optimal threshold in the ROC curve and the area under the curve were calculated. Results:(1) There were statistically significant differences in burn index, ABSI on admission, severity of inhalation injury, total burn area, full-thickness burn area, rehydration coefficient at the first 24 h after injury, use of ventilator, use of CRRT, and Baux score on admission of patients between the two groups ( Z=-7.696, -7.031, χ2=18.304, 63.065, 23.300, 13.073, 34.240, 59.586, t=-7.536, P<0.01). (2) There were statistically significant differences in death, incidence and severity of inhalation injury, total burn area, and burn index of patients between with ventilator group and without ventilator group ( χ2=34.240, 17.394, 25.479, Z=-6.557, -7.049, P<0.01). (3) There were statistically significant differences in death, total burn area, and burn index of patients between with CRRT group and without CRRT group ( χ2=62.982, Z= -47.421, -6.678, P<0.01). (4) The use of ventilator, use of CRRT, and burn index were independent risk factors for the death of extremely severe burn patients (odds ratio=3.277, 5.587, 1.067, 95% confidence interval=1.073-10.008, 2.384-13.093, 1.038-1.096, P<0.05 or P<0.01). (5) The initial concordance index of nomogram predicting model was 0.90 and the corrected concordance index was 0.89. The concordance indexes before and after correction were higher and similar, which showed that the nomogram had good concordance and predictive effect. The optimum threshold of ROC curve was 0.23, the sensitivity and specificity of optimum threshold were 86.0% and 80.0%, respectively, and the area under ROC curve was 0.90 (95% confidence interval=0.86-0.94, P<0.01). Conclusions:Severe burns and damage and/or failure of organ are the main death causes of extremely severe burn patients. The death risk nomogram predicting model established on the basis of use of ventilator, use of CRRT, and burn index have good predictive ability for death of extremely severe burn patients.

To analyze statistically the situation of the National Natural Science Foundation of China (NSFC) from 2007 to 2016 in the field of acupuncture and moxibustion for supporting the national Universities colleges of traditional Chinese medicine on the General Program (GP) and the National Science Fund for Young Scholars (NSFYS). In view of five aspects, named fund, supporting units, key words, method, disorder and signal path, the differences were compared between GP and NSFYS, the following characteristics were summarized. ① The fund aid was increased from 2007 through 2013 and down-regulated from 2013 through 2016. In recent ten years, the funding condition was fluctuated, but increasing in tendency generally. ② The relevant projects of the same research direction had been approved continuously for over 3 years in a part of TCM universities, in which, the research continuity was the hot topic. ③ Regarding the therapeutic methods, acupuncture was the chief therapy; electroacupuncture, moxibustion and acupoints were involved as well. ④ The disorders involved in the research were cerebral ischemia, myocardial ischemia and reperfusion injury. It is suggested that the ischemic disorder is predominated in the research. ⑤ The signal path occupied the main research index system, including cell proliferation, metabolism, immune, apoptosis and autophagy. The researches on the other aspects were less.
