ObjectivesTo study the effect of community interventions and management on asthma in children and its impact on knowledge, attitude, and practice (KAP)of parents and the home environment.MethodsAn asthma health management profile of 0 to 14-year-old asthmatic children (n =93 ) in Sanlitun and Liulitun communities in Chaoyang District in Beijing was established.The children were randomly divided into a management group ( n =49) and control group ( n =44 ) based on community.Community-integrated management,such as regular follow-up,condition monitoring and health education,was implemented in the asthmatic children in the management group but not in the control group.The parents' KAP and the household environment in the two groups were compared after 1 year based on the changes shown in the health management profile.ResultsThe asthma relapse rate decreased to 27.9％ (12/43) in the management group.Compared with the control group,the rates of hospitalization (x2 =8.174,P =0.004) and school absences ( x2 =4.962,P =0.026) significantly decreased.The KAP level of parents increased to 67.4％ ( 29/43 ) in the management group and 20.4％ (9/44) in the control group,and the difference was statistically significant (x2 =19.517,P ＜0.01 ).Knowledge improved the most and showed a significant difference from the control group ( x2 =19.517,P ＜0.01 ).Home environment in the management group improved to 76.7％ (33/43).The number of indoor pets ( x2 =3.906,P =0.048) and indoor cockroaches ( x2 =4.962,P =0.026 ) reduced and showed significant differences between the two groups.In addition,children's allergy-related symptoms decreased to 30.2％ ( 13/43 ) in the management group compared with 9.1％ (4/44) in the control group,which was a significant difference ( x2 =6.183,P =0.013).ConclusionsParents' knowledge of asthma,compliance behaviors,and home environmentwere effectively improved through community-integrated management.This management technique can reduce the allergy-related symptoms of asthmatic children,improve asthma severity,and reduce the influence of asthma on children's daily lives.

Objective To evaluate the effect of sevoflurane anesthesia on left ventricular synchroni?zation in patients undergoing coronary artery bypass grafting ( CABG ) . Methods Twenty?six patients of both sexes, aged 45-75 yr, with body mass index of 19-30 kg∕m2 and body surface area 1.4-2.0 m2 , of American Society of Anesthesiologists physical status Ⅱ or Ⅲ and New York Heart Association class ⅡorⅢ, undergoing elective CABG with cardiopulmonary bypass, were divided into 2 groups using a random number table: control group ( group C, n=11) and sevoflurane group ( group S, n=15) . After induction of general anesthesia, the patients were endotracheally intubated and mechanically ventilated. Anesthesia was maintained with iv infusion of propofol 4-6 mg·kg-1 ·h-1 , remifentanil 0. 2-0. 3 μg·kg-1 ·min-1 and cisatracurium 0.10-0.15 mg·kg-1·h-1, and intermittent iv boluses of fentanyl 0.5 μg∕kg, and bis?pectral index value was maintained at 40-60. In group S, sevoflurane ( end?tidal concentration: 2.05% for 45-49 yr, 1.80% for 50-59 yr, 1.60% for 60-75 yr) was inhaled for 30 min starting from 15 min after termination of cardiopulmonary bypass, followed by 30 min washout. The parameters of cardiac function
were monitored using transesophageal echocardiography. After induction and before sternotomy, immediate?ly before sevoflurane inhalation, at 30 min of sevoflurane inhalation, and at 30 min of washout, heart rate, mean arterial pressure, central venous pressure, pulmonary artery occlusion pressure, cardiac output, left ventricular ejection fraction, standardized standard deviation of time to peak systolic longitudinal strain of R?R interval ( Tssl?SD) of 17 left ventricular segment, and standardized standard deviation of time to peak systolic circumferential strain of R?R interval ( Tssc?SD) of 16 left ventricular segment were recorded. Re?sults Cardiac output and left ventricular ejection fraction were within in the normal ranges in the two groups. Compared with group C, heart rate was significantly decreased at 30 min of sevoflurane inhalation and 30 min of washout, and mean arterial pressure, cardiac output and left ventricular ejection fraction were significantly decreased at 30 min of sevoflurane inhalation in group S (P<0.05 or 0.01). There were no significant differences in standardized Tssl?SD and standardized Tssc?SD between group S and group C ( P>0.05) . Conclusion Sevoflurane anesthesia has no marked effect on the left ventricular synchronization in patients undergoing CABG.

A benzyl functionalized ionic liquid, 1-benzyl-3-methylimidazolium bis [( trifluoromethyl ) sulfonyl]imide ([BeMIM][Tf2 N]), was synthesized and characterized as an extraction solvent of dispersive liquid-liquid microextraction ( DLLME) for enrichment and determination of 5 organophosphorus pesticides (phoxim, fenitrothion, chlorpyrifos, phorate and parathion) and 2 aromatic compounds (chloronaphthalene and anthracene) from environmental water samples by high-performance liquid chromatography ( HPLC). [BeMIM] [ Tf2 N] had higher extraction efficiency than 1-octyl-3-methylimidazolium bis [( trifluoromethyl) sulfonyl]imide and common organic solvents such as CCl4 and C2 Cl4 . The extraction was performed using 40 μL of [BeMIM][Tf2N] and 1 mL of methanol as extraction solvent and dispersive solvent respectively with centrifugal time of 5 min. Under the optimal conditions, the method proposed here provided a good linearity for all analytes with correlation coefficients between 0. 9994 and 0. 9998. The repeatability values, described as intra-day and inter-day relative standard deviations (RSDs) of five replicate experiments at three different concentrations of 10, 40 and 100 μg / L, were 1. 1% -4. 3% and 0. 8% -4. 8% , respectively. The limits of detection (LOD) were 0. 01 μg / L-1. 0 μg / L at a signal-to-noise ratio (S / N) of 3. This developed method was convenient and speedy, and could be employed to detect the analytes in three real environmental water samples with satisfactory relative recovery of 82. 7% -118. 3% and RSD of 0. 7% -5. 6% . Introduction of benzyl group into the imidazolium could obviously enhance the extraction efficiecny for analytes due to the π-πinteraction between [BeMIM] [ Tf2 N] and analytes. [ BeMIM] [ Tf2 N] was a satisfactory extraction solvent with a high enrichment factor of 339 and extraction efficiency of 81. 4% . Partition coefficients of all analytes in [BeMIM][Tf2 N]-DLLME system were determined and the extraction mechanism was discussed.

Objective To investigate the autophagy capacity in clear cell renal cell carcinoma tissue compared with adjacent normal tissue.Methods Sixty-nine pairs of samples from human clear cell renal cell carcinoma tissues and relatively healthy renal tissues adjacent to the tumor were collected during surgical resection.The expressions of proteins that were participating in the regulation and execution of autophagy were detected by immunohistochemisty.Electron-microscopy was also carried out for the morphometrical analysis.Results The protein expression of p-mTOR (P =0.004),P62 (P =0.000) and ULK1 (P =0.000) were up-regulated in the carcinoma tissue,while the expression of Beclin1 (P=0.000),LC3 (P =0.000) and ATG7 (P =0.000) were down-regulated,and the expression of ATG5 (P =0.349) had no signif-icant difference compared with adjacent normal tissue.Morphometrical analysis showed that the basal autophagic activity (measured by the presence of autophagy vacuole compartment) was remarkably down-regulated in carcinoma tissue,compared with adjacent normal tissue.The expression level of mTOR was correlated with P62,LC3 and ATG7,but results showed no correlation between mTOR and Beclin 1.Conclusion Our studies show a relatively reduced autophagy capacity in clear cell renal cell carcinoma,which is regulated by multiple autophagy-related proteins such as mTOR,Beclin 1 and LC3.

Objective:To explore the clinical effect of simultaneous whole-course hyperfractionated intensity-modulated radiation therapy combined with chemotherapy and nimotuzumab in the treatment of advanced nasopharyngeal carcinoma.Methods:A total of 64 patients with advanced nasopharyngeal carcinoma who were admitted to Kaiping Central Hospital of Guangdong Province from June 2017 to January 2019 were selected and divided into the observation group and control group according to the random number table method, with 32 cases in each group. Both groups were given chemotherapy and nimotuzumab on the basis of radiotherapy. The observation group received simultaneous whole-course hyperfractionated intensity-modulated radiation therapy, and the control group received conventional fractionated intensity-modulated radiation therapy. The short-term efficacy, Karnofsky score, overall survival rate, progression-free survival rate, acute radiation reaction, and late radiation injury in the two groups were observed.Results:Six months after radiotherapy, the efficient rate of the observation group was higher than that of the control group [96.9% (31/32) vs. 75.0% (24/32), χ2 = 6.335, P < 0.05]. At the end of radiotherapy and 3 months after the end of radiotherapy, the Karnofsky scores of the observation group were higher than those of the control group, and the differences were statistically significant [(75±3) points vs. (71±3) points, t = 5.891, P < 0.05; (80±4) points vs.(77±4) points, t = 3.201, P = 0.002]. All patients were well tolerated, no grade 4 acute radiation reaction was observed, and radiotherapy was completed as planned. The incidence rate of oral mucosal reaction in the observation group was lower than that in the control group [21.9% (7/32) vs. 50.0% (16/32), χ2 = 5.497, P < 0.05]. The incidence rates of severe dry mouth and neck soft tissue fibrosis in the observation group were lower than those in the control group [6.2% (2/32) vs. 28.1% (9/32), χ2 = 5.379, P = 0.043; 3.1% (1/32) vs. 21.9% (7/32), χ2 = 5.143, P < 0.05]. The follow-up time was 14-20 months, and the median follow-up time was 17 months. There was no statistical difference in overall survival time between the two groups ( χ2 = 0.553, P = 0.557). The progression-free survival time of the observation group was better than that of the control group ( χ2 = 3.954, P = 0.044). Conclusion:The simultaneous whole-course hyperfractionated intensity-modulated radiation therapy combined with chemotherapy and nimotuzumab are effective in the treatment of advanced nasopharyngeal carcinoma, and the adverse reactions can be tolerated.
