ABSTRACT: Data management has significant impact on the quality control of clinical studies. Every clinical study should have a data management plan to provide overall work instructions and ensure that all of these tasks are completed according to the Good Clinical Data Management Practice (GCDMP). Meanwhile, the data management plan (DMP) is an auditable document requested by regulatory inspectors and must be written in a manner that is realistic and of high quality. The significance of DMP, the minimum standards and the best practices provided by GCDMP, the main contents of DMP based on electronic data capture (EDC) and some key factors of DMP influencing the quality of clinical study were elaborated in this paper. Specifically, DMP generally consists of 15 parts, namely, the approval page, the protocol summary, role and training, timelines, database design, creation, maintenance and security, data entry, data validation, quality control and quality assurance, the management of external data, serious adverse event data reconciliation, coding, database lock, data management reports, the communication plan and the abbreviated terms. Among them, the following three parts are regarded as the key factors: designing a standardized database of the clinical study, entering data in time and cleansing data efficiently. In the last part of this article, the authors also analyzed the problems in clinical research of traditional Chinese medicine using the EDC system and put forward some suggestions for improvement.

Venous thromboembolism includes deep venous thrombosis and pulmonary embolism. It is a more common and preventable complication in neurology. The prevention of venous thromboembolism is an important component in the treatment of the patients with cerebral hemorrhage. The measures include mechanical prevention and drug prevention. The mechanical prevention measures include intermittent pneumatic compression devices and pressure gradient elastic stockings. Studies have suggested that anticoagulants also plays an important role in the prevention of venous thromboembolism. The comprehensive and systematic understanding of the prevention of venous thromboembolism wil help to guide the clinical therapy and improve the outcomes of patients after primary intracerebral hemorrhage.

OBJECTIVE: To evaluate the efficacy and the safety of low dose budesonide/formoterol combination therapy vs.medium dose of budesonide(BUD) dry powder in the management of mild or moderate adult asthma.METHODS: A total of 62 patients with asthma were randomized to Group A(budesonide plus formcterol) or Group B(budesonide).Main outcome measures: daytime symptom and nocturnal symptom,peak expiratory flow(PEF),number of times of using rapid-acting ? 2 agonist and its ADR.RESULTS: After treatment,both groups had significant improvement in daytime symptom and nocturnal symptom(number of times of wakeup),PEF value and lung function,and the dosage of rapid-acting ? 2 agonist was decreased,showing significant differences between the two groups.The ADR was light in degree.CONCLUSION: Inhalation therapy of low dose of glucocorticoid plus long-acting ? 2 agonist is an optimal choice in the management of asthma.The efficacy of glucocorticoid could be enhanced more by combination with low dose and long-acting ? 2 agonist than by simply increasing its own dose.

Objective To analyze the isolation rates and antimicrobial resistance of Acinetobacter baumannii (AB) from intensive care unit (ICU)between 2010 and 2013,and provide evidence for clinical anti-infective therapy. Methods The isolation and antimicrobial resistance of AB from ICU between 2010 and 2013 were analyzed retro-spectively.Results A total of 1 413 pathogenic strains were isolated,556(39.35%)of which were AB,isolation rates in each year were 39.45%,41 .35%,29.44%,and 40.53% respectively.AB were mainly isolated from lower respiratory tract (75.72%).Antimicrobial susceptibility testing results showed that AB had low resistance rates to cefoperazone/sulbactam(5.85%)and amikacin (17.45%);detection rates of multidrug-resistant and extensively drug-resistant AB increased from 9.63% and 3.70% to 42.50% and 31 .88%,respectively (both P < 0.001 ). Conclusion AB is the common pathogen in ICU,antimicrobial resistance is serious,isolation of multidrug-resistant and extensively drug-resistant AB increased year by year;intensifying the monitoring of drug resistance is helpful for the treat-ment and prevention of AB infection.

Objective To investigate the mortality risk factors of nosocomial infection patients in intensive care unit (ICU), and to guide clinicians to take effective control measures. Methods A retrospectively cohort study was conducted. The relevant information of patients with nosocomial infection treated in ICU of Hengshui Harrison International Peace Hospital Affiliated to Hebei Medical University from June 2009 to December 2015 was analyzed. The patients who admitted to ICU again, with length of ICU stay less than 48 hours, without first etiology of screening within 48 hours of ICU admission, or without complete pathogenic information were excluded. The gender, age, diagnosis, length of ICU stay, invasive operation, nutritional status, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score, sequential organ failure assessment (SOFA) score, distribution and drug resistance of the pathogens, and procalcitonin (PCT) levels at 7 days after nosocomial infection were recorded. The risk factors leading to death in patients with nosocomial infection were analyzed by logistic regression, and the receiver operating characteristic curve (ROC) was drawn to evaluate the predictive value of all risk factors on the outcome of patients with nosocomial infection. Results In 864 enrolled patients with male of 54.75% and mean age of (63.50±15.80) years, 732 (84.72%) patients survived and 132 (15.28%) died. Compared with survivors, the non-survivors had higher age (years: 65.47±15.32 vs. 58.15±13.27), incidence of urgent trachea intubation (32.58% vs. 22.81%), deep venous catheterization (83.33% vs. 63.25%), and multiple drug-resistant infection (65.91% vs. 33.20%), longer length of ICU stay (days: 13.56±4.29 vs. 10.29±4.32) and duration of coma (days: 7.36±2.46 vs. 5.48±2.14), lower albumin (g/L: 23.64±8.47 vs. 26.36±12.84), higher APACHEⅡ score (19.28±5.16 vs. 17.56±5.62), SOFA score (8.55±1.34 vs. 6.43±2.65), and PCT (μg/L: 3.06±1.36 vs. 2.53±0.87, all P < 0.05). There was no significant difference in gender and urinary tract catheterization between survivors and non-survivors (both P > 0.05). The low respiratory tract was the most common site of infection followed by urinary tract and bloodstream in both groups. It was shown by logistic regression analysis that prolonged ICU stay [odds ratio (OR) = 2.039, 95% confidence interval (95%CI) = 1.231-3.473, P = 0.002], APACHEⅡ score (OR = 1.683, 95%CI= 1.002-9.376, P = 0.000), SOFA score (OR = 2.060, 95%CI = 1.208 -14.309, P = 0.041), PCT (OR = 2.090, 95%CI = 1.706-13.098, P = 0.004), and multi-drug resistant pathogens infection (OR = 5.245, 95%CI = 2.213-35.098, P = 0.027) were independent risk factors for ICU mortality in patients with nosocomial infection. The area under ROC curve (AUC) of length of ICU stay, APACHEⅡ score, SOFA score, and PCT level for predicting death of nosocomial infection patients was 0.854, 0.738, 0.786, and 0.849, respectively, the best cut-off value was 16.50 days, 22.45, 6.37 and 3.38 μg/L, respectively, the sensitivity was 83.6%, 90.0%, 81.1%, and 89.6%, and the specificity was 70.3%, 75.6%, 71.3%, and 85.4%, respectively. Conclusions Prol onged ICU stay, nosocomial infection with secondary sepsis and multiple organ dysfunction syndrome were the leading causes of death for nosocomial infection patients in ICU. Prolonged ICU stay, APACHE Ⅱ score, SOFA score, and PCT level could effectively predict death risks for nosocomial infection patients.

Objective:To compare the effectiveness between three methods for purifying the immunoglobulin of egg yolk(IgY) which are polyethylene glycol (PEG) method, chloroform extraction method and chloroform / PEG method, and to provide basis for obtaining the batch of IgY.Methods:The inactivated vaccine of Vibrio parahemolyticus (V. parahemolyticus) was prepared and the hens were immunized by multi-point intramuscular injection.The eggs were collected and the IgY was purified by PEG method, chloroform extraction method and chloroform/PEG method.The protein extraction rate, the IgY titer and the purity of the antibody which purified by different methods were detected.Furthermore, the operation process, cost and safety of the three methods were analyzed.Results:The protein contents of the extraction belonging three methods from high to low in turn were chloroform extraction method, chloroform/PEG method, and PEG method.There was no significant difference in the antibody titer between three methods, and the tiler of chloroform extraction method was slightly high.The purities of purified antibody from high to low in turn were PEG method, chloroform/PEG method and chloroform method.The PEG method had better security but relatively lower extraction efficiency and higher cost.The chloroform/PEG method had high extraction efficiency and good antibody purity.Conclusion:The PEG method is suitable for a small amount of extraction in the laboratory.The chloroform/PEG method is appropriate for extracting the high quality IgY in a batch as it has high extraction efficiency and good antibody purity.

ObjectiveTo investigate the influence of the number of T-junctions between central venous catheter and pressure transducer on measurement of central venous pressure (CVP) in patients.Methods A prospective controlled study was conducted. The patients with CVP monitoring in Department of Critical Care Medicine of the Fifth Center Hospital in Tianjin from February to October in 2014 were enrolled. The patients were divided into three groups according to the number of T-junction between central venous catheter and pressure transducer: without T-junction control group and 1, 2, 3 T-junctions groups. In each patient, corresponding CVP values with different number of T-junctions placed between the central venous catheter and pressure sensors were determined within a certain period, and a square-wave graphic was obtained and preserved on the monitor. The own frequency (fn) and the attenuation coefficient (D) of the system of pressure measurement were calculated after measurement of the shock wave following a square-wave to obtain the distance between two vibrations and the amplitude of the shock wave. The difference in CVP, fn and D were compared among the groups.Results A total of 20 cases were enrolled, and 150 groups of data were collected.① With the increase in the number of T-junction, CVP showed a tendency of gradual reduction. The CVP of the groups of control and 1, 2, 3 T-junctions was (7.00±1.60), (7.00±3.00), (5.00±2.00), and (4.00±1.00) mmHg (1 mmHg = 0.133 kPa), respectively. The CVP of 3 T-junctions group was significantly lower than that of the control group (F = 9.333,P = 0.015).② With an increase in the number of T-junction, fn showed a tendency of gradual increase. The fn of groups control and 1, 2, 3 T-junctions was (12.30±0.79), (16.00±0.91),(18.10±1.75), (20.90±2.69) Hz, respectively. The fn of 1, 2, 3 T-junctions group was significantly higher than that of the control group (F1 = 45.962,F2 = 45.414,F3 = 46.830, allP = 0.000); the fn of groups 2 and 3 T-junctions was significantly higher than that of 1 T-junction group (F1 = 5.827,P1 = 0.042;F2 = 15.038,P2 = 0.004), but there was no significant difference between the groups of 2 T-junctions and 3 T-junctions (F = 3.800,P = 0.087).③ With an increase of the number of T-junction, D also showed a tendency of gradual increase. The D of 1, 2, 3 T-junction group was 1.62±0.27, 1.60±0.22, 1.82±0.25, and 2.15±0.58, respectively. There were no differences among four groups.ConclusionAfter the application of T-junctions between central venous catheter and pressure transducer, CVP values will be underestimated, the reason of which is considered to be the increase in length and thinner lumen of the T-junctions.

OBJECTIVETo study the effect of tongfei mixture (TFM, a Chinese recipe mainly consisted of angelica and rehmannia root) on nocturnal hypoxia in patients with chronic obstructive pulmonary disease (COPD).

METHODSSixty patients with COPD of remission phase were randomly divided into 3 groups, 20 in each group. Group A was the control group; Group B, the group simply treated with oxygen; Group C, treated with oxygen and TFM. Changes of pulmonary function, diaphragm muscle mobility (DMM), 6 min walk distance (6MWD), morning arterial blood gas, nocturnal lowest oxygen saturation (LSaO2), mean blood oxygen saturation (MSaO2), the percentage of saturation lower than 90% time account for total sleeping time (SLT90%) and ultrasonocardiogram before and after treatment were observed.

RESULTSLevels of LSaO2, MSaO2 and SLT90% in Groups B and C were significantly higher than those in Group A (P<0.05, P<0.01). The lowering of PaCO2 in Group C was more significant than that in Group B (P<0.05). The mPAP level in Group C was lower, FEV1, 6MWD and DMM were improved than those in Group A and B, showing significant difference (P<0.05).

CONCLUSIONCombined use of oxygen therapy and TFM could not only improve the nocturnal hypoxia, but also lower PaCO2. TFM is an important supplement of oxygen therapy.
