ABSTRACT
With the reform of trade unions in China, there has been a noticeable interaction in recent years between trade unions and human resource management in the workplace. However, we do not have a proper concept to describe such a phenomenon. Therefore, based on reviewing the current literature involving trade unions and human resource management in China, this study aims to describe the interactive relation between union's practices and enterprises' human resource management by exploring the definition, characteristics, and formation mechanism. This study defines the relationship between the trade unions and human resource management as a coupling relationship where the trade unions and human resource management continually promote and restrain each other as two relatively independent systems in the enterprise. This relationship possesses three dual characteristics, namely reciprocity vs. restraint, integrity vs. independence, and stability vs. dynamism. And there are three sequential stages for trade unions and human resource management to form such a relation, interaction, consensus, and adjustment. This study provides further insight into the relationship between trade unions and human resource management in the workplace and attempts a proximately complete description of the relationship. The study also offers a direction for trade unions and enterprises to establish high-quality cooperation with each other which is mutually beneficial for enterprises' development and employees' wellbeing.
ABSTRACT
Work fatigue refers to physical, mental, and emotional exhaustion, resulting in the inability to work. Hitherto research indicate a close relationship between high-performance work systems and work fatigue, and there may be a double-edged sword effect of high-performance work systems on work fatigue. However, a comprehensive theoretical framework has not been developed to understand the relationship between them. Based on the challenge-hindrance stress model, this study employs role overload and job responsibility as mediating variables in a conceptual framework to understand the impact of high-performance work systems on work fatigue. Using the partial least square structural equation model and a sample of 360 employees in China, the mediating effects of role overload and job responsibility were confirmed. Further, the internal mechanisms of how high-performance work systems affect work fatigue are discussed, its adverse effects are confirmed, and its practical implications are proposed.

Improving the well-being of the employees is the inevitable choice to improve corporate performance and competitive advantage and the social responsibility that enterprises must undertake. Based on the job demands-resources model, this study introduces perceived organizational support and work stress as the mediator and trade union practice as the moderator to explore the double-edged sword effect of a high-performance work system (HPWS) on the well-being of the employee. Taking 243 employees from Jiangsu, Zhejiang, and Anhui as samples, we found that HPWS positively affects the well-being of the employee through perceived organizational support and negatively affects the well-being of the employee through work stress. Union practices can significantly reduce the positive effect of HPWS on work stress and further weaken the negative effect of HPWS on the well-being of the employee through work stress. The results of this study provide a new way to explain the impact of the HPWS on the well-being of the employees and find that union practice can weaken the negative effects of HPWS. This study provides a new thinking direction for improving the well-being of employees in enterprises.
ABSTRACT
Objective@#To describe the mortality trend of major malignant tumors in Shandong province, from 1970 to 2013.@*Methods@#Data related to cancer mortality were obtained from the Shandong Death Registration System and three nationwide retrospective cause-of-death surveys. Trends of overall mortality and major causes of death were described using the indicators as: mortality rates and age-standardized mortality rates, through comparing the three large-scale mortality surveys in Shandong province. Difference decomposing method was applied to estimate the contribution of demographic and non-demographic factors for the change of mortality.@*Results@#From 1970 to 2013, the crude mortality rate of malignant tumors in Shandong was increasing. The age standard mortality rate was increasing and then decreasing. The composition of cancer deaths in the all-cause-deaths was seen increasing and then decreasing as well. Both demographic and non-demographic factors contributed to the increase of crude cancer mortality rate. With the gradual increase of the proportion of population, its role exceeded the non-demographic factors. The age-standardized mortality rate of malignant tumors in 2011-2013 was lower than that in 2004-2005. Lung cancer mortality rose from the fifth to the first place, with an increase of 6.81 times from 1970-1974 to 2011-2013. Ranking of gastric cancer mortality dropped from first to the third place, with esophageal cancer dropped from second to the fourth. After adjusted by China’s standard population in 1964, the mortality rate of lung cancer was still rapidly increasing, but the age-standardized mortality rates of esophageal cancer was gradually decreasing. The crude and age-standardized mortality rates of cervical cancer showed a rapid downward trend, reduced 87.00% and 93.00% respectively from 1970-1974 to 2011-2013.@*Conclusions@#Malignant tumors were still major threats to the residents of Shandong province. The changing trend of different malignant tumors presented an inconsistent nature which called for different intervention strategies be carried out, accordingly.

Objective To investigate the clinical value of color Doppler ultrasound in the early diagnosis of acute cholecystitis infection ,in order to improve the diagnosis of acute cholecystitis infection .Methods 36 cases with acute cholecystitis infection were selected as the observation group , and during the same period the healthy people were randomly selected as the control group .The color Doppler performance of ultrasound was observed .The hepatic artery blood flow velocity and the maximum peak of the cystic artery (Vmax) and resistance index(RI) were meas-ured.ROC curve was observed to evaluate the specificity of color Doppler ultrasound for the disease .Results The incidence rates of weak bile sound transmission ,gallbladder wall thickness ,gallbladder enlargement ,ultrasound Mur-phy positive in the control group were 25.0%,16.7%,22.2%,8.3%,which in the observation group were 72.2%, 47.2%,100.0%,94.4%,the differences were statistically significant (χ2 =4.571,4.571,4.589,5.689,all P0.05).Conclusion Color Doppler ultrasound can show the form of acute infectious cholecystitis ,gallbladder wall degree of bile through sound etc .,it can improve the diagnostic value of the disease.
ABSTRACT
This study is to investigate the amelioration effect of glucocorticoid receptor (GR) antagonist mifepristone on the changes of learning and memory abilities in rat model of depression. In the present study, a 35-day rat chronic unpredictable stress (CUS) model was used to observe both depression-like behaviors with sucrose preference test and open-field test and learning and memory-associated behaviors with Morris water maze test. A total of 45 male adult Sprague-Dawley rats were randomly assigned to three groups of equal size: control group (CON); CUS group (CUS); CUS + mifepristone group (CM). Animals in CM group were first exposed to CUS for 14 days, and then were administered with 50 mg x kg(-1) x d(-1) of mifepristone with continued CUS procedure. Corticosterone EIA Kit was used to detect the concentration of plasma corticosterone (CORT). Nissl staining was used to observe the structure of hippocampus. The results demonstrated that CUS exposure induced both depressive-like and learning and memory-associated behaviors and these deficits were reversed by mifepristone. Compared to CON group, the concentration of plasma CORT increased significantly in CUS group. CUS exposure damaged the structure of hippocampus, whereas mifepristone had an amelioration effect. Together, the structural deficits of hippocampus resulting from long-term stress exposure, which could contribute to the impairment of learning and memory in depression, are reversed by the GR receptor antagonist mifepristone.
ABSTRACT
Aim To study of the expression and distribution of four α-synuclein truncations in three cells.Method Four α-synuclein gene truncations were obtained by PCR method,followed by subcloning into the pEGFP-N1 eukaryotic expression vector.Four obtained recombination plasmids were transfected into MN9D cells,PC12 cells and SH-SY5Y cells using Lipofectamine 2000 respectively.The expression and distribution of four α-synuclein truncations were observed by Confocal.Results Distribution of four α-synuclein truncations was discrepant obviously,the truncations,with more C terminal remained,were prone to emerging in nuclei.Conclusion Localization of α-synuclein protein in cells may be related to the C terminal,and the whole C terminal plays an important role in distribution of α-synuclein into nuclei.
ABSTRACT
Abstract:Aim To study the effect of rotenone on α-synuclein in rat midbrain of Parkinson's disease(PD).Methods Rats were subcutaneouly injected with chronic low dose rotenone(1.0 mg·kg~(-1)·d~(-1)).Movements within 5 minutes were evaluated in open field test.Tyrosine hydroxylase(TH)-positive neuronsin the midbrain were measured with immunofluorescence staining.α-SYN protein level in the midbrain was demonstrated with immunohistochemical staining and Western blot.Results Compared to the control group,latency time,crossing,rearing and rearing time were changed significantly(P<0.05,0.01)in the rotenone group,TH-positive neurons were reduced(P<0.05)and α-SYN protein level in the midbrain was increased(P<0.05).Conclusion Injection with rotenone can induce PD symptom,which may be correlated to α-SYN protein level in the midbrain.
