Objective To explore the clinical value of clara cell protein 16 (Cc 16) in the early diagnosis of ARDS in critically ill patients.Methods A total of 55 critically ill patients admitted between March 2013 and December 2013 in the Intensive Care Unit were enrolled for study.The inclusion criteria were as follows:sepsis,pneumonia,multiple injuries,patients after emergency or elective operation and non-cardiogenic diseases,whereas the exclusion criteria were cardiogenic pulmonary edema,age ≤ 18 years or≥80 years and disease course prolonged over one week.The level of serum Cc16 was detected with enzyme linked immunosorbent assay (ELISA).In addition,data of other biochemical examinations,the Acute Physiology and Chronic Health Evaluation (APACHE]Ⅱ) score and the relevant medical data were documented.The patients were divided into ARDS groups and non-ARDS groups based on clinical data met Berlin definition.Results The sensitivity and specificity of serum Cc16 for diagnosis of ARDS were 92％ and 80％,respectively with the area under the curve being 0.92,which were better than those of APACHE Ⅱ score,D-dimer,C-reactive protein,N-terminal pro-brain natriuretic peptide and serum albumin detected by the means of receiver operating characteristic curve,and cut off value was 20.62 ng/L.The bivariate analysis showed there was negative correlation between Cc16 and oxagenation index in ARDS patients and the Pearson correlation coefficient of serum Cc16 with oxygenation index was r =-0.342 (P =0.04).The results of one-way analysis of variance showed difference in level of Cc16 between subgroups (F =15.76,P =0.005 17).The level of Ccl6 in severe ARDS group was (64.18 ± 12.95) ng/L which was higher than that in mild ARDS group (35.87 ± 11.28) ng/L (P =0.001 14),and in moderate ARDS group (38.66 ± 20.14) ng/L (P =0.004 9),and in non-ARDS group (16.72 ± 8.74) ng/L (P =0.000 32).There was no statistically significant difference in Cc16 level between mild ARDS group and moderate ARDS group (P =0.682).The level of serum Ccl6 did not correlate with type or days of respiratory ventilation support,28-day survival rate or 120-hour survival rate and days of ICU stay and hospital stay.Conclusions The diagnostic value of serum Cc16 is very high in determining the presence and severity of ARDS in addition to the Berlin criteria in critically ill patients accurately assessing degree of lung injury.

Acute respiratory distress syndrome (ARDS) is a common diseases in critical ill patients, which is an acute-onset hypoxic condition with radiographic bilateral lung infiltration. And it can be divided into two phases in pathophysiology: an acute exudative phase combining diffuse alveolar damage and lung edema followed by a later fibro proliferative phase. The early prediction and risk assessment of patients with ARDS is still very poor in the clinical. In recent years, researchers gradually focus their research on exploration of biomarkers of ARDS. The article mainly aims to sum up the development of biomarkers exploration.

Objective To investigate the clinical effect and safety of the cell therapy of inhibition of antigen -presentation attenuators ( iAPA ) combined with adjuvant chemotherapy in the treatment of colon cancer . Methods From February 2014 to October 2015,the clinical data of 40 patients with colon cancer in the People＇s Hospital of Wenzhou were analyzed retrospectively.They were divided into control group and study group by the random digital table,with 20 cases in each group.The control group received mFOLFOX6 chemotherapy(treatment for 6 months),and the study group was treated with iAPA on the basis of the control group (treatment for 6 cycle).The clinical efficacy,levels of immune function indicators ( CD+3,CD+4,CD+8,CD+4/CD+8) before treatment and after treatment,the incidence of toxic and side effects and quality of life (QOL) score of the two groups were recorded.And the survival rates were statistically analyzed.Results The total effective rate of the study group was higher than that of the control group (85.0% vs.55.0%,χ2＝4.286,P＜0.05).After treatment,the serum levels of CD +3,CD+4,CD+8,CD+4/CD+8in the study group were higher than those in the control group,while the serum level of CD +8was lower in the study group than that in the control group,the differences were statistically significant (t＝2.657,3.160,5.700,2.326,all P＜0.05).There were no side effects of the degree of Ⅳin the two groups.The incidence rates of diarrhea(25.0%),vomiting and nausea (20.0%),liver function damage (25.0%) and bone marrow suppression (25.0%) in the study group were lower than those in the control group (χ2＝5.013,5.227,5.013,6.465,all P＜0.05).After treatment,the QOL scores of the two groups were higher than those before treatment (all P＜0.05),and the QOL score of the study group was higher than that of the control group (t＝4.739,P＜0.05).The survival rate of the study group was higher than that of the control group after 24 and 30 months of treatment(χ2＝5.013,4.912,all P＜0.05 ).Conclusion The iAPA combined with adjuvant chemotherapy in the treatment of colon cancer can regulate the immune function of the patients,and improve the treatment effect of the disease.It helps to improve the QOL and prolong the life period of the patients,reduce the incidence of side effects,and it is safe.

OBJECTIVE: To explore the genetic basis for a Chinese pedigree affected with inherited afibrinogenemia. METHODS: For the proband and his family members, prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), Fibrin(ogen) degradation products (FDPs), D-dimer (D-D), plasminogen activity (PLG:A) and the TT mixed experiment with protamine sulfate were determined with a STAGO-R automatic coagulation analyzer. The activity and antigen of fibrinogen (Fg) in plasma were measured with the Clauss method and immunonephelometry method, respectively. All exons and flanking regions of the fibrinogen genes (FGA, FGB and FGG) were amplified by PCR and directly sequenced. Human Splicing Finder software was used to predict and score the change of splicing site caused by the mutation. RESULTS: The proband showed normal FDPs and D-D but significantly prolonged TT, PT and APTT. The activity and antigen of fibrinogen in plasma were significantly decreased (<0.1 g/L). His young sister and parents showed slightly prolonged TT (18.20-18.50 s) and decreased fibrinogen activity (1.27-1.54 g/L) and fibrinogen antigenic content (1.34-1.56 g/L). Genetic testing revealed that the proband has carried homozygous IVS7-12A>G (g.4147A>G) mutations of the FGG gene, for which his parents and young sister were heterozygous. As predicted by Human Splicing Finder and Mutation Taster software, the variant may generate a new splicing site which can extend the sequence of exon 7 by 11 bp, with alteration of the coding sequence. PROVEAN suggested the variant to be deleterious. CONCLUSION The afibrinogenemia of the proband may be attributed to the FGG IVS7-12A>G variant, which was unreported previously.

Objective:To share the implementation experience of hierarchical first aid training scheme for elementary and middle school students in Baoan District of Shenzhen City and evaluate its effect of training. Methods:During August 2018 and August 2019, elementary and middle schools students who participated in the first aid training held by emergency rescue training center of Baoan District were enrolled. Baseline information including the number of students, the number of attending tutors, the number of cardiopulmonary resuscitation (CPR) training models, automated external defibrillator (AED) models were recorded. According to hierarchical levels of three age, students received different courses with content from simple to hard: the course of elementary school students was consisting of dialing 120, smart animation on how to identify accidental damage, demonstration of AED and Hemlick techniques, CPR practise (40 minutes). The course of junior high school students was consisted of how to dial 120, how to identify accidental damage and simple disposal, application of CPR and AED, practice CPR and AED and Hemlick techniques (90 minutes). The course of high school students was consisted of how to dial 120, identify accidental damage and right disposal, identification of out-of-hospital cardiac arrest, the key-point of CPR and AED, practice CPR and AED, Hemlick techniques and hemostatic bandage (120 minutes). At the end of course, elementary school students were voluntary for skill assessment; junior high school students only were compulsory for skill assessment in small classes but not required in large classes, just for demonstration; additionally, the whole high school students were compulsory for skill assessment. The characteristics of first aid training students at different levels were collected in order to compare the differences on the usage of CPR training model and AED training model, the distribution of emergency resource, the ratio for passing examination.Results:A total of 12 896 students and 2 086 training instructors took parted in 200 lists of first aid training courses, 8 557 CPR models and 8 493 AED models were used. On average, there are 65.27±5.61 students in each session, and 10.52±10.43 training instructors. There are 43.09±19.06 CPR training models and 42.77±18.61 AED training models. The mean ratio of student to tutor was 6.07±1.47, student to CPR model was 1.54±1.02, and student to AED model was 1.54±1.03. In the end of course, 10 494 students participated in the examination with the participation rate of 81.37%; 10 114 students passed the examination with the passing rate of 96.38%. Hierarchical analysis showed: compare to elementary school students, the average number of junior high school students in every training session significantly increased (cases: 69.94±8.77 vs. 58.69±6.12, P < 0.05), but the average number of high school students in every training session significantly decreased (cases: 57.35±5.79 vs. 58.69±6.12, P < 0.05). The proportion of instructors in junior high school students' training significantly reduced (5.94±1.39 vs. 6.48±2.02, P < 0.05). The examination ratio of junior high school students and high school students was increased significantly [81.07% (6 667/8 224), 100% (2 313/2 313) vs. 64.18% (1 514/2 359), both P < 0.05], but the ratio of passing the examination was significantly reduced [95.47% (6 365/6 667), 96.88% (2 241/2 313) vs. 99.60%(1 508/1 514), both P < 0.01]. This might be related to the low difficulty of elementary school students' assessment and the low proportion of compulsory examination. Conclusions:Hierarchical scheme is feasible for first aid training in elementary and middle school students, the content of course should be desighed from easy to hard. Synchronously, sufficient training instructors and training models should be equipped to ensure the quality.
