ABSTRACT
Aim: To investigate the grip strength of older patients with gastrointestinal tumours and analyse its explanatory factors. Methods: A total of 170 older patients with gastrointestinal tumours admitted to the Gastrointestinal Surgery Department of a Grade-III hospital in the Zhejiang province from January 2022 to December 2022 were selected as the investigation participants. Among them, there were 102 cases of gastric cancer (60.0%) and 68 cases of colon cancer (40.0%). There were 110 male patients (64.7%) and 60 female patients (35.3%), with patient ages ranging between 64 and 82 years old. A cross-sectional survey was conducted using a general data questionnaire, grip apparatus and the Nutritional Risk Screening 2002 (NRS-2002) score. Multiple linear regression was used to analyse the explanatory factors on the grip strength of older patients with gastrointestinal tumours. Results: The grip strength of older patients with gastrointestinal tumours was 25.3±5.3 kg. Multiple linear regression analysis showed that gender, age, disease, body mass index (BMI), albumin concentration and the NRS-2002 score were the main explanatory factors on grip strength (P<0.05). Conclusion: Grip strength was lower in older patients with gastrointestinal tumours and was lower in females, those aged ≥70 years, patients with colorectal cancer, individuals with a BMI of <18.5, those with an albumin concentration of <35g/l and those with an NRS2002 score of ≥3. Clinical staff should dynamically evaluate the level of grip strength in patients with gastrointestinal tumors and develop individualized interventions based on the related explanatory factors.
ABSTRACT
Safety behavior is one of the focal concerns to occupational health researchers and safety managers. This study examined the relationship between authoritarian leadership and safety behavior based on social exchange theory and locus of control theory, and further explored the mediating role of trust in leadership and the moderating role of locus of control. In this study, a total of 636 employees from petroleum enterprises were recruited, with random sampling used to collect data in two stages. The result showed that: (1) Authoritarian leadership is significantly and negatively related to employees' safety compliance behavior and safety participation behavior. (2) Trust in leadership plays a partially mediating role in the impact of authoritarian leadership on employees' safety compliance behavior and safety participation behavior. (3) Locus of control moderates the first half of the pathway through which authoritarian leadership affects employees' safety behavior through trust in leadership. For externals, the negative effect of authoritarian leadership on their trust in leadership is stronger, which in turn decreases their safety compliance behavior and safety participation behavior.

OBJECTIVE: To analyze the status of government health expenditure in Xinjiang Uygur Autonomous Region since the first 10 years from the new medical reform, and find the existing problems in order to provide evidence for the government to formulate medical and health policies. METHODS: Based on the health expenditure monitoring data of Xinjiang Uygur Autonomous Region government from Urumqi Central Sub-branch of the People's Bank of China, combined with the relevant data in Xinjiang statistical yearbook, Excel2013 and SPSS19.0 were used to conduct a comparative analysis of government expenditure data from 2009 to 2018. RESULTS: The average annual growth rate of the government's health expenditure in Xinjiang Uygur Autonomous Region was 12.25%, which was similar to the national level. The proportion of government health expenditure in gross domestic product increased from 0.97% to 1.07%, while the proportion in the total fiscal expenditure decreased from 3.06% to 2.63%, which led to far behind the national and even western area level. The Gini Coefficient of per capita government health expenditure in every city (state) of the autonomous region fell from 0.46 to 0.32 between 2014 and 2018. In the past decade, the ratio between public health expenditure and medical institution expenditure has decreased from 1.01 to 0.42, led to insufficient proportion of public health expenditure. The health expenditure level of the four prefectures especially Kashgar and Hotan in Southern Xinjiang was still far lower than the whole autonomous region and the national average level. CONCLUSION: The government of Xinjiang Uygur Autonomous Region should continuously strengthen the financial expenditure in health, maintain the current situation of preferential policy implementation for rural and grassroots expenditure, constantly optimize the proportion of various financial expenditures, and strive for the transfer payment from the central and autonomous regional governments to the four prefectures in Southern Xinjiang.
ABSTRACT
A label-free electrochemical method for the detection of DNA-PNA hybridization using a water-soluble, ferrocene-functionalized polythiophene transducer and single-stranded PNA probes on the nanogold modified electrode is investigated. Nanogold modified electrodes can largely increase the immobilization amount of ss-PNA capture probe and lead to an increase of the electrical signal. The ferrocene-containing cationic polythiophene do not interact electrostatically with the PNA probes due to the absence of the anionic phosphate groups on the PNA probes. But after DNA-PNA hybridization, cationic polythiophene is adsorbed on the DNA backbone, giving a clear hybridization detection signal in differential pulse voltammetry (DPV). Very good discrimination against non-complementary DNA and four-base mismatch DNA is observed. These studies show that the proposed method can provide an alternative for expanding the range of detection methods available for DNA hybridization.
