Objective To investigate the effects of ulinastatin on pro- and anti-inflammatory cytokines and respiratory index during open heart surgery under CPB. Methods Twenty ASA Ⅱ- Ⅲ patients of either sex (9 males, 11 females) scheduled for elective valve replacement under CPB were randomly divided into two groups of 10 each : control group (C) and ulinastatin group (W) . Patients with hepato-renal dysfunction or taking glucocorticoid were excluded. The patients were premedicated with intramuscular phenobarbital 0.1 g and scopolamine 0.3 mg. Anesthesia was induced with midazolam 0.1 mg?kg-1 , fentanyl 10?g?kg-1 and vecuronium 0.1mg?kg-1 . After tracheal intubation anesthesia was maintained with midazolam and fentanyl. The patients were mechanically ventilated. VT was set at 8-12 ml?kg-1 , RR 10-12 bpm and I: E 1:2. PETCO2 was maintained at 35-45 mg. In ulinastatin group, the patients received ulinastatin 12 000 U?kg-1 of which half was given i.v. before CPB and half was added to the priming fluid, while group C received normal saline instead of ulinastatin. Blood samples were taken from radial artery for determination of plasma TNF-?, IL-6, and IL-10 concentrations and blood gas analysis before operation (T1 ) , 30 min after initiation of CPB (T2), 1 h (T3 ) , 4 h (T4 ) and 24 h (T5 ) after CPB. Respiratouy index (PA-aDO2/ PaO2) was calculated at T1-5 .Results There were no significant differences in sex, age, weight, height, duration of CPB, and aortic cross-clamping time between the two groups. In group C the plasma levels of TNF-?, IL-6 and IL-10 were significantly higher than the baseline values (T1 ) during and after CPB (P

High expression of Fightless I (FLII) is associated to multiple tumors. Based on our previous study that FLII might be involved in the nuclear export, we assessed the possible interaction of FLII with the nuclear envelop associating proteins Importin β and Nup88. We first constructed GST-FLII, GST-LRR recombinant plasmids and transformed them into the Rosetta strain to produce GST-FLII, GST-LRR fusion protein. After purification of these proteins, GST-pull down, as well as co-immunoprecipitation, were used to test the interaction of FLII with Importin β and Nup88. FLII interacted with Importin β and Nup88, and FLII LRR domain is responsible for these interactions. Thus, FLII may play a role in nuclear export through interaction with Importin β and Nup88.

Objective: To explore the prevalence of body weight control behaviors (BWCB) among middle school students in Jiangsu province. Methods: The database was established part from the surveillance of adolescent common disease and health related factors in Jiangsu province in 2017 and analysis were carried out to describe the prevalence rates of four basic BWCB and their comorbidity. Results: Among 18 855 investigators, 75.8% middle school students reported having taken at least one kind of BWCB within 30 days before investigation, the report rates of BWCB of middle school students among male and female were 77.3% and 74.3%(P<0.01), showed decreasing tendency from grade 1 of junior middle school to grade 3 of senior middle school (Kendall’s tau-c=-0.10, P<0.01), those of malnutrition, normal body weight, overweight and obesity were 57.2%, 72.8%, 83.8%, 86.7% respectively and showed increasing tendency(Kendall’s tau-c=0.13, P<0.01). Reported rate of Changing diet structure, physical exercise, reducing diet and taking slimming drug prevalence were 58.7%, 61.0%, 17.9%, 2.6%, orderly. There are 15 combinations of BWCB based on those 4 kinds of behavior. In the highest five types list ,changing diet structure & physical exercise (35.2%) was the most common type, and followed by physical exercise(13.0%), Changing diet structure(9.2%), Changing diet structure & physical exercise & reducing diet(8.6%), Changing diet structure & physical exercise & reducing diet(3.4%), others 6.5%. The proportions of top five kinds of BWCB among middle school students taken BWCB were 46.4%, 17.1%, 12.2%, 11.3%, 4.5%, respectively, accounting for 91.5%. The probabilities of different types of BWCB were similar between urban and town(χ2=9.13, P=0.10), different among sex(χ2=351.17, P<0.01), districts(χ2=140.20, P<0.01), school type and nutrition status(χ2=343.95, 309.62, P<0.01). Conclusion Some overweight or obesity students report on control body weight, while some report taking medicine and reducing diet behavior. Health education on healthy body weight should be implemented for middle school students to cultivate healthy body image so as to keep healthy body weight.

Objective:To assess the left ventricular (LV) myocardial mechanical dysfunction in patients with cirrhosis using ultrasonic layer-specific strain imaging and to explore its value in clinical application.Methods:A total of 80 consecutive cirrhosis patients without cardiovascular diseases were prospectively enrolled from October 2020 to March 2021 in Sichuan Provincial People′s Hospital, 39 of whom were assigned to the compensated group and 41 were assigned to the decompensated group according to the occurrence of portal hypertension. Forty-three healthy volunteers during the same period were randomly recruited as the control group. Transthoracic echocardiography was performed to assess the LV configuration and functional parameters. LV global longitudinal strain in endocardial, middle and epicardial myocardium (GLSendo, GLSmid, GLSepi), and longitudinal strain (LS) in basal, middle and apical segments, and peak strain dispersion (PSD) were obtained using ultrasonic layer-specific strain imaging. ΔLS was calculated by the formula of GLSendo-GLSepi. Then, the differences of related parameters among three groups were compared.Results:①Conventional echocardiography: compared with the control group, the interventricular septum end-diastolic thickness (IVSTd), left ventricular posterior wall end-diastolic thickness (LVPWd), left ventricular mass (LVM) and LVM index (LVMI) were increased in compensated and decompensated groups (all P<0.05), while no significant differences in conventional echocardiographic parameters were identified between the two cirrhosis groups (all P>0.05). ②Global layer-specific strain: compared with the control group, GLSendo, GLSmid, GLSepi and ΔLS were decreased and PSD was increased in compensated and decompensated groups (all P<0.05); Moreover, the decompensated group showed a more impaired GLSendo, GLSmid and GLSepi than compensated group (all P<0.05), whereas there were no significant differences of ΔLS and PSD between the two groups(all P>0.05). ③Segmental layer-specific strain: compared with the control group, LS values of three layers in compensated and decompensated groups were reduced at basal, middle and apical levels (all P<0.05); Compared with the compensated group, LS values of three layers in decompensated group tended to be reduced at above there levels, but only apical segments had significant differences (all P<0.05). Conclusions:There are different degrees of LV mechanical dysfunction in patients with variable severity of cirrhosis. Ultrasonic layer-specific strain imaging has the potential to quantitatively assess the state of cardiac involvement in patients with cirrhosis and to provide visual evidence for the early and accurate diagnosis of myocardial injuries.

Objective To assess the factors associated with the restoration of spontaneous circulation (ROSC) and 2-year survival prognosis in patients with cardiac arrest (CA) after acute myocardial infarction (AMI),and after ROSC,the effects of various factors on midian survival time and on 2-year survival.Methods In a registry study from January 2005 to January 2015,all consecutive AMI-induced CA patients treated with cardiopulmonary resuscitation (CPR) admitted to our hospital were enrolled.The survivors were followed-up for 2 years.Univariate analysis was applied to evaluate factors associated with rate of ROSC and 2-year survival.Multivariable logistic regression analysis was applied to evaluate statistically significant factors in the univariate analysis.Medians with inter-quartile ranges were used to describe 2-year survival time affected by various factors after ROSC.Kaplan-Meier survival curve analysis was used to evaluate the effect of factors on 2-year survival.Results A total of 254 cases with CA after AMI were enrolled,including 129 cases of ROSC and 71 cases of 2-year survival.Univariate analysis showed age ≥ 70 years,CA occurred during 22:00-8:00,the duration time ofCPR ≥ 15 min and adrenaline dosage ＞ 5 mg were unfavorable predictors of ROSC;while,left ventricular ejection fraction (LVEF) ≥ 40％ before CA,shockable rhythm and percutaneous coronary intervention (PCI) therapy were favorable predictors.Besides,age ≥ 70 years,intubation during CPR,adrenaline dosage ＞ 5 mg and cardiogenic shock were unfavorable predictors of 2-year survival;While,male,normal daily activity before CA and PCI treatment were favorable predictors.Multivariable analysis showed age,the duration of CPR,adrenaline dosage,LVEF before CA,the rhythm during CPR and PCI therapy were independent predictors of ROSC.Age and PCI therapy were independent predictors of 2-year survival.Among patients,the survival time was affected by various factors after ROSC,and the factors with minimum 25％ and small median value were associated with cardiac rupture,cancer,adrenaline dosage ＞ 5 mg and cardiogenic shock.The factor with maximum 25％ value was PCI treatment (216 days).Kaplan-Meier survival analysis suggested that age ≥ 70 years was an unfavorable factor of 2-years survival (Log-rank test,P=0.007);while,PCI treatment was a favorable factor (Log-rank test,P＜0.01).PCI-related prognosis analysis showed that the effectiveness of PCI was related to the timing of PCI,the number of infarctrelated artery and the difference in culprit lesion.Conclusions The age ≥ 70 years was disadvantageous to both ROSC and 2-year survival.PCI treatment was favorable to both ROSC and 2-year survival.

OBJECTIVETo identify the enterovirus from stool samples of patients with hand, foot and mouth disease(HFMD) in Guangzhou from 2010 to 2012 and to perform phylogenetic analysis of the VP1 gene sequences of coxsackievirus A4 and coxsackievirus A10.

METHODSA total of 5 484 samples of suspected cases of HFMD which Guangzhou Center for Disease Control received from 2010 to 2012 were collected.Virus RNA was tested by nested RT-PCR method as human enterovirus 71, coxsackievirus A16, coxsackievirus A4, coxsackievirus A10 and other enteroviruses positive, and 4 111 samples were positive. Phylogenetic tree was constructed by partial VP1 gene sequences of coxsackievirus A4 and coxsackievirus A10 to perform phylogenetic analysis.

RESULTSIn 4 111 enterovirus-positive samples, the positive rate of EV71, CoxA16, CoxA10 and CoxA4 was 35.1% (1 443/4 111) , 30.7% (1 261/4 111) , 2.0% (82/4 111),0.8% (31/4 111) respectively. Different enterovirus-positive rate was statistically significant (χ(2) = 148.34, P < 0.05) .Incidences of coxsackievirus A4 positive was highest in 3-year old children as 1.3% (7/534) , and that of coxsackievirus A10 positive was highest in 0-year old children as 3.7% (34/914) . The highest positive rate of diagnosed coxsackievirus A4 positive cases was admitted in April(2.6%, 12/460) , and the highest positive rate of diagnosed coxsackievirus A10 positive cases was admitted in August 4.3% (12/278). Phylogenetic analysis indicated that all the CoxA4 stains were divided into subtype A and subtype B, and the CoxA10 stains were divided into subtypes A, subtype B and subtype C. The VP1 gene nucleotide sequences of CoxA4 and CoxA10 this study measured both belonged to subtype A.

CONCLUSIONSThe VP1 gene nucleotide sequences of CoxA4 and CoxA10 in Guangzhou from 2010 to 2012 both belonged to subtype A.

Objective: Based on physical activity (PA) and sedentary behavior (SB) variables on weekdays and weekends, the study aims to cluster the physical activities inside and outside kindergartens and to explore the cluster characteristics of different children using physical fitness indicators, so as to provide new strategies and methods for early childhood education and health. Methods: From March to June 2019, 291 children aged 3-6 years from 6 kindergartens in Nanchang were recruited by a stratified cluster random sampling method. The ActiGraph GT3X-BT triaxial accelerometer was used to measure and analyze the PA and SB levels inside and outside the kindergarten. A twostep clustering algorithm model was employed for cluster analysis. Physical fitness were measured and evaluated according to the "National Physical Fitness Measurement Standard Manual (Preschool Section)". Differences in physical fitness among different clusters of children were compared, and the cluster characteristics of different children were analyzed. Results: The clustering algorithm model indicated that based on six indicators, including PA and SB inside the kindergarten on weekdays, and PA and SB outside the kindergarten on both weekdays and weekends, children could be divided into three categories:active inside (high PA, low SB inside), active outside (high PA outside), and inactive (low PA, high SB both inside and outside). The average silhouette coefficient of the model was 0.3, indicating good clustering results. Both the active inside and active outside children showed significantly higher PA inside on weekdays, PA outside on weekdays and weekends, daily low intensity physical activity (LPA) and moderate-to-vigorous physical activity (MVPA) than the inactive children ( F=157.91, 80.79 , 95.86, 95.52, 124.74, P <0.05). After adjusting for gender and age, the physical fitness scores of both active outside ( 19.03 ±0.47) and active inside (19.11±0.40) were significantly higher than those of the inactive children (17.94±0.31). Additionally, active inside children (3.91±0.14) also showed significantly better performance in continuous double-leg jumps, compared to inactive children (3.45±0.11) ( P <0.05). Conclusion Children active inside and those active outside perform well in PA. Future research should focus on the proportion of structured and unstructured PA time to enhance the overall physical fitness of children.
