Objective To investigate the development trends of domestic cardiopulmonary bypass(CPB) in the past eight years.Methods Domestic hospitals that carry out cardiovascular sugeries were inquired with questionnaires annually up-on the number of on-pump and off-pump cardiac operations,oxygenators of different types and extracorporeal membrane oxygenations.Classify all the hospitals according to the cardiac surgery amount.Analyze the market share of each grade and the composition of oxygenators.Results The sum amount of cardiac operations and CPB were 170 547 and 136 753 respectively in 2010.In 2010,the composition of imported membrane oxygenator climbed up to 59.75％ from 43.22％ in 2003,while bubble oxygenator composition decreased from 43.78％ to 14.59％.44 hospitals carried out ECMO in 2010 and the sum number of ECMO was 206.The market share of hospitals( 32),with cardiac surgery number over 1000 per year,was 43％.Conclusion CPB in China has went through a rapid development in the past eight years.Medical resources of CPB should be concentrated and normal and systematic train regulations should be established in the future.

Objective The study aimed to explore the application of fast track surgery in nursing of patients with colon cancer in a primary hospital.Methods The 60 colon cancer patients were identified with numbers to indicate randomization into the fast tract surgery group (group A) and the conventional treatment group (group B) with 30 cases in each group.Group A used the concept of fast track surgery (FST) perioperative nursing care,whereas traditional perioperative nursing care for colon cancer was used in group B.Patients in both groups were observed for postoperative time for passage of gas by anus,time for first food intake,length of stay in hospital,fee for hospitalization as well as incidence of postoperative complications,and comparative analysis was carried out.Results Time for passage of gas by anus(t value was 3.571),time for first food intake (t value was 8.944),length of stay in hospital (t value was 3.397),fee for hospitalization (t value was 3.950) as well as incidence of postoperative complication in group A were lower than those of group B.The satisfaction degree of group A was 96.67％(29/30) while 83.33％(25/30) in group B and the satisfaction degree between the two groups was statistically significant.Conclusions In the primary hospital,the fast track surgery care used in colon cancer can not only speed up the recovery process of the patients,shorten hospital stay,reduce hospital cost and the incidence of postoperative complications,but also can reduce the workload of nurses and improve the satisfaction degree of patients.

Objective: Auricularid auricula polysaccharide was isolated from Auricularia auricula, and then iron(Ⅲ)-Auricularia auricula polysaccharide complex(APC) was prepared. Methods: APC was synthesized with FeCl 3 and its physico-chemical property and bioavailability were determined. Results: APC was able to dissolve in water and its solution assumed neutral, and this complex did not precipitate at pH from 3 to 11 in water solution, so APC was very stable. Fe(Ⅲ) in APC could be reduced to Fe(Ⅱ) by ascorbic acid. Extracorporeal dissolubility showed Fe(Ⅲ) in APC could be exhibited in 6 h. Bioavailabity studies showed the iron from APC could be well absorbed and maintained longer in serum concentration. Conclusion: APC was able to have better bioavilability as an iron supplement.

Objective To observe changes in the working memory and brain functional imaging on functional magnetic resonance imaging(fMRI) after 36 hours sleep deprivation (SD) in healthy volunteers and to explore the possible mechanism of the changes.Methods FMRI scannings were performed in ten male healthy young volunteers before and after 36 hours SD and results were analyzed using SPM2 software.Subjects were also tested LTR and PLUS task to measure the persistence and operation of working memory before and after 36 hours SD.Results The reaction time of LTR task after 36 hours SD ( (866 ± 102) ms)was significantly longer than that before SD ( (754 ± 91 ) ms, t = 2.59, P < 0.01 ).The reaction time of PLUS task after SD ( (848 ± 94) ms) was significantly longer ( t = 2.37, P < 0.05 ) than that before SD ( (756 ± 79) ms).The error rate of LTR task after SD (95.3% ± 3.56% ) was significantly higher (t=3.52,P < 0.01 ) than that before SD (84.8% ± 8.71% ).The error rate of PLUS task after SD (95.7% ±4.72% ) was significantly higher (t =3.38 ,P <0.01 ) than that before SD (84.2% ±9.66% ).There were no significant differences between the two tasks.The frontal and parietal lobes, anterior cingulate gyrus and thalamus were activated during memory tasks testing before SD.Brain activation was broader and stronger in PLUS task than in LTR task.After SD, activation in parietal lobe was decreased and activation in prefrontal and thalamus was increased significantly.Conclusions The working memory performance decreased after SD.Both LTR and PLUS tasks of working memory activate frontal and parietal lobes, anterior cingulate gyrus and thalamus.The activation of parietal lobe decreased and the activation of prefrontal lobe and thalamus increased after 36 hours SD.This is the possible mechanism of SD to causes the cognition decline.

ObjectiveTo study the expression changes of peripheral blood monocyte human leukocyte antigen DR (HLA-DR) in patients with severe craniocerebral injury,and investigate the correlation between HLA-DR expression and infection and prognosis.MethodsNinety patients with craniocerebral injury were selected as experimental group and were divided according to the Glasgow coma scale (GCS) score after hospitalization into experimental group 1 (GCS score 13-15 scores ),experimental group 2 (GCS score 9-12 scores) and experimental group 3 (GCS score 3-8 scores) with 30 patients each,which were moderate,medium,severe craniocerebral injury,respectively.Thirty healthy people were chosen at the same period as control group.The HLA-DR expression of experimental group was detected after 1,3,7 and 14 d of admission by flow cytometry,and the HLA-DR expression of control group was detected on the day they got physical examination.The rates of infection,cure,disability,vegetative state and mortality were counted after 30 d of admission.ResultsThe HLA-DR expressions in experimental group 1 and experimental group 2 after 1,3,7,14 d of admission were (28.11 ± 2.37),(26.45 ± 1.63),(27.75 ± 1.83),(27.15 ± 2.17) MCF and (29.34 ±2.07),(27.55 ± 1.63),(28.42 ± 1.94),(29.46 ±2.12) MCF,which had no statistical difference compared with that in control group [(29.18 ± 1.91 ) MCF](P＞ 0.05).The HLA-DR expressions in experimental group 1 and experimental group 2 after 1,3,7 d of admission and control group had statistical differences compared with those in experimental group 3 after 1,3,7 d of admission [(18.02 ± 1.78),(16.05 ± 1.97 ),(20.76 ± 1.65) MCF ] (P ＜ 0.05).The HLA-DR expressions in experimental group 1 and experimental group 2 after 14 d of admission and control group had no statistical significance compared with that in experimental group 3 after 14 d of admission [ (26.13 ± 2.15) MCF](P＞ 0.05).The infection rates of experimental group 1,experimental group 2 and experimental group 3 were 0,3.6％(1/28),82.8％(24/29),respectively,while the cure rates were 100.0％ (30/30),100.0％ (28/28),10.3％ (3/29),the disability rates were 0,0,41.4％ (12/29),the vegetative state rates were 0,0,20.7％ (6/29),and the mortality were 0,0,27.6％ (8/29).There was no statistical significance in the rates of infection,cure,disability,vegetative state and mortality between experimental group 1 and experimental group 2 (P＞ 0.05 ).While there was statistical differences in the rates of infection,cure,disability,vegetative state and mortality among experimental group 1,experimental group 2 and experimental group 3 (P ＜ 0.05).ConclusionsThe HLA-DR expression changes of patients with moderate and medium craniocerebral injury after 1,3,7,14 d of admission are not significant.The HLA-DR expression of patients with severe craniocerebral injury begins to decline from 1 d after injury,declines obviously at 3 d,increases from 7 d,returns to normal level at 14 d.The decline of HLA-DR expression in patients with severe craniocerebral injury is correlated with the infection,and predicts poor prognosis.

Objectives To explore the effects of budesonide (BUD) on airway remodeling and the levels of transforming growth factor-β1 (TGF-β1) in bronchoalveolar lavage fluid (BALF) and its expression in lung tissue of asthmatic rats. To provide a theoretical basis for the intervention and treatment of asthma. Methods Sixty healthy adult male Wistar rats were randomly divided into 3 groups: control group, asthma model group and BUD treated group, 20 rats in each group. A rat asthma model was established by ovalbumin (OVA) challenging. BUD treated group was treated with inhaled BUD 1 mg/kg in 30 min per serving every other day for two weeks. After OVA challenge finished, the rats were anesthetized and sacrificed for BALF and lung tissue collection. The level of TGF-β1 in BALF was measured by enzyme-linked immunosorbent assay. TGF-β1 expression and collagen deposition in the lung tissue were tested with immunohistochemical determination and Masson stain respectively. The computer image analysis system was used for measuring respiratory bronchiole smooth muscle thickness (μm) and the extent of epithelial damage score and other indicators of airway remodeling. Results Compared with that in the control group, TGF-β1 in BALF and lung tissue of asthma model group increased and were correlated significantly with the indicators of airway remodeling (P < 0.01) ;while that of BUD treated group reduced statistically significant than model group (P < 0.05). Pathology examination on asthma rat airway epithelial tissue showed the thickness of airway smooth muscle, the airway deposition of collagen in BUD treated group reduced obviously than asthma model group. Conclusions The expression of TGF-β1 in the rat asthma airway worsens the airway remodeling. The effects of BUD on ameliorating the progression of airway remodeling may be partially made by reducing the expression of TGF-β1. (J Clin Pediatr,2010,28(2):173-177)

Objective To explore the factors that affect the prognosis of extensive small cell lung cancer by analyzing the association between lab-oratory indicators before treatment of extensive small cell lung cancer patients and the initial evaluation results with disease progression and overall survival. Methods This study retrospectively analyzed 96 cases of hospitalized patients in the medical oncology department of The First Hospital of China Medical University from March 2008 to September 2014. Kaplan-Meier method and Cox proportional hazards models were adopted to ana-lyze the relevant factors affecting the prognosis of extensive small cell lung cancer. P<0.05 was considered statistically significant. Results There was no obvious correlation between HB level before treatment with PFS of patients(P=0.179),but there was obvious significant correlation be-tween HB level and OS of patients(P=0.041). Our results showed that the TBIL level of patients before chemotherapy was significantly associated with the PFS(P=0.039)and OS(P=0.026)of patients. Conclusion HB and TBIL levels are the influencing factors that affect the prognosis and survival of patients with extensive small cell lung cancer.
