ABSTRACT

Objective:To assess the correlation between frailty and cardiac autonomic nervous system function in elderly patients.Methods:Elderly hospitalized patients aged 65 years and over were enrolled and assessed for frailty by using the clinical frailty scale.Cardiac autonomic modulation was evaluated by heart rate variability analysis through 24 h electrocardiogram recording.Results:A total of 180 elderly patients were enrolled in this study, including 66 patients with frailty and 114 patients without frailty.The mean age of the frailty group was higher than that of the non-frailty group(79.8±6.0 vs.75.0±6.3, t=5.030, P<0.001). The proportions of patients with hypertension, stroke/transient cerebral ischemia attack(TIA), heart failure and osteoarthritis were higher in the frailty group than in the non-frailty group(all P<0.05). Compared with the non-frailty group, the standard deviation of normal-to-normal intervals(SDNN)[103.0(76.0, 121.2) vs.107.5(92.0, 136.0), Z=-2.108, P=0.035], the standard deviation of the averages of NN intervals in all 5-min segments(SDANN)[86.0(67.7, 106.5) vs.97.5(78.0, 126.0), Z=-2.694, P=0.007], normalized low frequency(LFnorm)(53.1±13.0 vs.59.3±13.9, t=-3.024, P=0.003)and low frequency/high frequency(LF/HF)ratio[1.2(1.0, 1.4) vs.1.4(1.1, 1.7), Z=-3.041, P=0.002]were decreased and normalized high frequency(HFnorm)(36.8±9.2 vs.32.2±10.7, t=3.033, P=0.003)was increased in the frailty group.HFnorm in the frailty group was significantly higher than that in the non-frailty group.The incidents of SDANN<92 ms, LFnorm<50 nU, HFnorm>32 nU and LF/HF ratio<1.5 were higher in the frailty group than in the non-frailty group(59.1% or 39/66 vs.41.2% or 47/114, 42.4% or 28/66 vs.22.8% or 26/114, 72.7% or 48/66 vs.49.1% or 56/114, 84.8% or 56/66 vs.65.8% or 75/114, χ2=5.346, 7.660, 9.547, 7.664, P=0.021, 0.006, 0.002, 0.006). Logistic multivariate regression analysis showed that LFnorm, HFnorm and LF/HF ratio were correlated with frailty( OR=0.971, 1.039 and 0.333, all P<0.05), and HFnorm>32 nU and LF/HF ratio<1.5 were risk factors for frailty( OR=2.401 and 2.773, both P<0.05). Conclusions:Cardiac autonomic nerve system function is impaired in elderly frail patients, with the imbalance between the sympathetic and vagus nerves.Therefore particular attention should be paid to heart rate variability in elderly patients with frailty.

ABSTRACT

Objective:To assess the cardiac autonomic nervous function in elderly patients with frailty.Methods:Patients aged ≥ 65 years old admitted in Beijing Hospital from September 2018 to August 2019 were enrolled in this study. Clinical frailty score was used to assess the frailty. The cardiac autonomic modulation was evaluated by sinus heart rate turbulence analysis through 24 h electrocardiogram recording.Results:A total of 129 elderly patients were finally enrolled in this study with a mean age of (77.5±6.4) years, 58.1% of them were male. There were 53 patients in frail group and 76 patients in non-frail group. The age of the frailty group was significantly higher than that of the non-frailty group [(80.5±5.5) vs.(75.3±6.2)]; the prevalence of hypertension [84.9%(45/53)], heart failure [32.1%(17/53)] and peripheral vascular diseases [32.1%(17/53)] in the frailty group was significantly higher than that in the non-frailty group [65.8%(50/76), 1.3%(1/76), 17.1%(13/76); t=5.001, χ 2=5.879, 24.606, 3.921; all P<0.05]. Compared with non-frailty group, turbulence onset (TO) [-0.05(-0.92, 0.82)% vs. -0.74(-1.58, 0)%; Z=2.616, P=0.009] was significantly higher in frailty group, while turbulence slope (TS) [2.34(1.30, 5.00)ms/RR vs. 4.34(2.66, 6.39)ms/RR; Z=-3.048, P=0.002] was significantly lower. The rate of TO abnormality [49.1% (26/53) vs. 26.3%(20/76), χ 2=7.038, P=0.008] and TS abnormality [34.7%(29/53) vs. 21.0%(16/76); χ 2=15.579, P<0.001] in the frailty group was significantly higher than that in the non-frailty group. Multivariate logistic regression analysis showed that TO abnormality( OR=2.970, P=0.010, 95 %CI:1.300-6.785) and TS abnormality( OR=3.618, P=0.003, 95 %CI:1.565-8.364) were correlated with frailty. Conclusion:Cardiac autonomic nerve function may be impaired in elderly frail patients, and decreased vagal nerve tension may be presented.

ABSTRACT

AIM: To investigate the role of transcription factor hairy and enhancer of split 1 (Hes1) in the malignant transformation of human bronchial epithelial cell line BEP2D induced by tobacco.METHODS: The BEP2D cells were chronically exposed to cigarette smoke condensate (CSC) at 1 cigarette per L until the 70th generation.The phenotype of malignant transformation of the cells induced by CSC was detected by soft agar clony formation assay.RT-PCR and Western blot were used to determined the expression of Hes1 at mRNA and protein levels in each generation of the cells.The proliferation and apoptosis of the BEP2D cells exposed to CSC were analyzed with the methods of MTT assay, flow cytometry and cell colony formation assay after treatment with Notch pathway bloker DAPT or liposome transfection with Hes1-siRNA.The expression of Hes1 in the peripheral small airway tissues of the smoking rats was evaluated by immunohistochemical staining.The expression of Hes1 in non-small-cell lung cancer and normal airway tissues was also detected by the methods of immunohistochemistry and RT-PCR.RESULTS: The BEP2D cells in the 70th generation had a malignant transformation phenotype.The expression of Hes1 in the BEP2D cells exposed to CSC for different time showed an increa-sing trend.DAPT and liposome transfection with Hes1-siRNA down-regulated the expression of Hes1, inhibited the cell proliferation and induced cell apoptosis.The expression of Hes1 in the airway mucosa of the rats exposed to cigarette smoke for 1 month and 6 months was significantly higher than that in control group.Cigarette smoking induced the expression of Hes1 in lung cancer and normal airway tissues.CONCLUSION: Hes1 may be involved in smoking-induced lung cancer by promoting the imbalance between apoptosis and proliferation.

ABSTRACT

OBJECTIVE:To observe clinical efficacy and safety of Bufeihuayu decoction combined with chemotherapy in the treatment of non-small cell lung cancer(NSCLC)and its effects on vascular endothelial growth factor(VEGF)and immune func-tion. METHODS:A total of 120 NSCLC patients in our hospital during Oct. 2013 to Jun. 2015 selected as research object were di-vided into observation group and control group according to random number table,with 60 cases in each group. Control group was given GP(gemcitabine combined with cisplatin)chemotherapy. Observation group was additionally given Bufei huayu decoction, one dose a day,decocted to 400 mL,morning and night,on the basis of control group. Clinical efficacies of 2 groups were com-pared,and VEGF-A,VEGF-B,VEGF-C and immune indexes (CD3+,CD4+,CD8+,CD4+/CD8+) levels were compared before and after treatment. The occurrence of toxic reaction was recorded. RESULTS:Response rate and disease control rate of observa-tion group were 58.33% and 85.00%,significantly higher than 40.00% and 68.33% of control group,with statistical significance (P<0.05). Before treatment,there was no statistical significance in levels of VEGF or immune indexes between 2 groups (P>0.05). After treatment,VEGF of 2 groups were decreased significantly,and observation group was significantly lower than the con-trol group,with statistical significance(P<0.05);CD4+and CD4+/CD8+of 2 groups were decreased significantly,while CD8+was increased significantly,with statistical significance(P<0.05);CD4+ and CD4+/CD8+ of observation group were significantly higher than those of control group,while CD8+ was decreased significantly;CD3+ of control group was decreased significantly and lower than observation group,with statistical significance (P<0.05). The incidence of leucopenia,thrombocytopenia,decrease of hemo-globin,elevation of transaminase,increase of bilirubin and digestive tract reaction in observation group was significantly lower than control group,with statistical significance(P<0.05).

ABSTRACT

Objective To investigate the characteristics of spinal injury caused by earthquake as well as to improve its therapeutic ability by comparatively studying the medical records of the inpatients with spinal injuries caused by Wenchuan earthquake and the inpatients with spinal injuries in peace time.Methods Medical records of inpatients with spinal injuries were extracted from 5.12 earthquake injury database(earthquake group) and medical records of the patients with spinal injuries firstly admitted to Daping Hospital between 2001 and 2007 were extracted from Chinese trauma database systems (control group).The epidemiological characteristics of the two groups were comparatively studied,including gender,age,injury causes,injury severity,treatments and outcomes.Results (1) The incidence of spinal injuries in the earthquake group was 16.7% (524/3145),which was significantly higher than that (6.4%,682/10644) in control group (P<0.01).(2) The female ratio in the earthquake group was significantly higher than that in the control group (57.4%:31.8%) (P<0.01).(3) The age range of the earthquake group was (47.9 ±20.9) years.The wounded number presented an undulately rising trend in the earthquake group as the growth of age,while it showed a parabolic distribution in the control group.(4)The main causes for spinal injuries were crush injury (69.3%) and multi-factor injury (2.8%) in the earthquake group,while slipping up/fall (56.0%) and traffic accidents (23.6%) were the main causes in the control group.(5) There were 82.3% of the earthquake group that were combined with multiple injuries and 48.1% combined with at least two injuries,while the control group accounted for only 28.9% and 12.0% respectively.The NISS (new injury severity score) in the earthquake group was significantly higher than that in the control group [(11.6±8.8) points vs (7.5±4.8)points](P<0.01).Meanwhile,the proportion of NISS≥16 in earthquake group was significantly higher than that in the control group as well (P<0.01).(6) The length of hospital stay of the wounded in the earthquake group was significantly longer than that in control group [(40.5±24.5)d VS (23.9±26.7)d](P<0.01).The treatment inefficiency rate in the earthquake group was higher than that in the control group (9.2% vs 4.8%) (P<0.01).Conclusions The earthquake group has a higher proportion of spinal injuries,female and elder cases,and combined injuries,a much severer injury,a longer length of hospital stay,and a higher treatment inefficiency rate,as compared with the control group.In the earthquake relief,more importance should be attached to salvage,diagnosis,transfer regulation and missed diagnosis,misdiagnosis and secondary injury should be avoided so as to improve the treatment level of the spinal injuries in earthquake.

ABSTRACT

Objeetive To analyze traffic accidents involving pedestrians in Chongqing from 2000 to 2006 so as to understand injury characteristics of the pedestrians. MethodsThe data of pedestrian road traffic crashes and injuries in three districts including one district in downtown,one in suburb and one in county of Chongqing from 2000 to 2006 were collected from road traffic crash and road traffic injury database to analyze severity of crashes,casualties,action and location of pedestrians in crashes. Results The road crashes led to 7 934 pedestrian injuries (24.74%) and 867 pedestrian deaths (49.46%).Intensity of the pedestrian road crashes in rural areas was higher than that in downtowns and suburbs.Of all pedestrian casualties,57.91% were due to illegally crossing the driveway,and 15.43% of the casualties were on the crosswalk.Most of the casualties occurred on the main roads,the third class highways and second main roads in Chongqing.But serious crashes occurred on the first and second class highways and substandard highways,which led to average 3.17,4.13 and 5.42 deaths,respectively.Pedestrians accounting for 52.46% of the total severe injuries were more than the proportion among the minor to moderate injuries.Head injuries were the most common for the pedestrians and chest injuries were also usual among the severe injuries. Conclusions The intensity of pedestrian road crashes is higher than that of other crashes,especially in rural areas.It should be noticed that the main injuries of the pedestrians are head injuries,which is mainly resulted from illegally crossing driveway.It is worth noticing that a rather high proportion of pedestrians are impaired on the crosswalks,indicating that we should pay more attention to protect right of the pedestrians on the crosswalks during transportation law enforcement and safety education in the future.

ABSTRACT

Objective To study the positive influence of a standard trauma system on the care of severely injured patients.Methods The severely injured patients (NISS≥16 points)were divided into study group ( in 2006-2008,after the establishment of trauma center in our hospital) and control group (in 2001-2005,before the establishment of trauma center),which was bound by the establishment of the trauma center in our hospital in January 2006.The injury severity,care and outcomes were recorded by using China Trauma Database and changes in efficiency and quality of injury care were compared.Results The study group (66 patients) and control group (260 patients) with NISS of (20.59 ±4.63)points and (20.57 ± 5.38 ) points respectively,were similar in the distribution of severity ( P > 0.05 ).The emergency care time was (0.33 ± 0.03) hour in the study group,which was significantly shortened compared with (0.57 ±0.35 ) hours in the control group (P < 0.01 ).The length of hospital stay was (27.64 ±29.01 ) days in the study group,which was shorter than (30.84 ± 32.87 ) days in the control group (P > 0.05 ),while the length of ICU stay was (2.98 ± 5.77 ) days in the study group,longer than (2.65 ± 7.00) days in the control group (P > 0.05 ).The recovery rate was significantly increased from 76.5% to 87.9% (P <0.05) and mortality was significantly decreased from 20.8% to 9.1% (P <0.05).Conclusion The study indicates that the standard first aid model can notably improve the trauma care in our hospital.

ABSTRACT

ObjectiveTo study the characteristics and risk factors of traffic injuries among the adolescents (0-19 years old) in the urban and rural areas of Chongqing and discuss the preventive strategy. MethodsData of road traffic crashes and injuries involving 0-19 years old adolescents over a seven-year period (2000-2006) in three districts of Chongqing was picked up from Road _Traffic Crashes and Injuries Database. Epidemiological characteristics of the traffic crashes and injuries among 0-19 years old adolescents were analyzed and differences between rural and urban areas were studied. ResultsFrom 2000 to 2006, both incidence rate and mortality rate peaked in the urban fringe area were 95.43/100 000 and 3.44/100 000 respectively. Traffic accidents in the suburbs and counties had the highest injury extent, with mortality rate of 9.06% and severe injury rate of 17.33%. Brain injuries were the primary cause of death. Among the victims, 62.7% were the pedestrians, of which 20.72% bore equal responsibility because of disobeying traffic signals, suddenly walking across roads and not walking along the sidewalk. Ninety percentage of the traffic accidents occurred in the sections with no traffic signals or traffic control system. ConclusionIt is important to enhance the traffic safety consciousness of teenagers and children, strengthen preventive measures in fringe areas and rural areas and improve the emergency medical system in rural areas to provide the teenagers and children with a safety traffic environment.

ABSTRACT

Objective To develop a special seismic trauma database that could record and analyze the data including injuries, trauma cares and outcomes. Methods (1) The items and content of the database were determined based on the method of evidence-based medicine. (2)The fields, tables, items and options of the seismic trauma database were designed. (3) The database software was developed based on dot net framework platform, with C# as programming language. (4)The database was used to record and manage data of injuries caused by 5.12 earthquake. Results The Seismic Trauma Database Version 1.0 was developed with 728 fields (including 380 inner fields) and normative content and structure. The database software could record 10 aspects of the seismic patients including basic information, injuries, transfer and evacuation, clinical medical care, outcome and discharge. The database software had combination, custom queries and meta-analysis functions. Conclusions This database software can conveniently and normally record and manage the information of the seismic patients, can systemize and analyze the data conveniently and is an excellent data platform for trauma care research and epidemiologic study of seismic injuries.
