Objective: To investigate the association between lifestyle risk factors and comorbidity of chronic diseases among male elderly populations in Oroqen Autonomous Banner, Inner Mongolia Autonomous Region, so as to provide insights into improvements of lifestyles and prevention of comorbidity of chronic diseases among male elderly populations. Methods: Male residents at ages of 65 years and older that participated in community healthy examinations were sampled from 16 villages (communities) in Oroqen Autonomous Banner using a multi-stage cluster random sampling method from July to December, 2020. Participants' demographic data, lifestyle risk factors and disease history were collected using questionnaire surveys, and healthy examinations data were collected through the grassroots healthcare service information system for community health service centers, including waist circumference, blood pressure, fasting blood glucose and blood lipid. The correlation between lifestyle risk factors and comorbidity of chronic diseases were examined among males at ages of 65 years and older using a multivariable ordered logistic regression model. Results: Totally 761 male elderly populations were included, with a mean age of (73.61±6.74) years. There were 216 participants with central obesity (28.38%), 179 with smoking (23.52%), 194 with alcohol consumption (25.49%), 412 with a low frequency of physical activities (54.14%), 347 with one type of lifestyle risk factor (45.60%) and 268 with two and more types of lifestyle risk factors (35.22%), 404 with hypertension, 170 with diabetes and 321 with dyslipidemia. There were 347 participants with one type of chronic disease (45.60%), 199 with two types of chronic diseases (26.15%) and 50 with three types of chronic diseases (6.57%), and the prevalence of comorbidity of chronic diseases was 32.72% among the participants. Multivariable ordered logistic regression analysis showed an increased risk of developing comorbidity of chronic diseases among participants with central obesity (OR=2.442, 95%CI: 1.804-3.307), and a reduced risk of comorbidity of chronic diseases among participants with less than two types of lifestyle risk factors (one type, OR=0.607, 95%CI: 0.451-0.820; none, OR=0.675, 95%CI: 0.460-0.990). Conclusions Central obesity and number of lifestyle risk factors are factors affecting comorbidity of chronic diseases among the male elderly populations at ages of 65 years and older in Oroqen Autonomous Banner.

A sequential clean-up method was developed for the quantification of 10 plant growth regulators in bean sprout by the gas chromatography / mass spectrometry (GC / MS). The analytes were firstly extracted by the acided acetonitrile. Extraction was concentrated and re-dissovled by methanol. Then, it was divided to two aliquots. One of that was analyzed for 2,4-D-butyl ester and 2,4-D-ethyl ester after the purification by QuECHERS cartridge. Another one was treated by MCS solid phase extraction column including diverse eluting steps. After eluting by 5 mL methanol, composition 1 was obtain, concentrated, and methyl esterified by 10% boron trifluoride methanol solution. The treated extract was used for the determination of 4-chlorophenoxy acetic acid, β-naphthyl acetic acid, 2,4-dichlorophenoxy acetic acid, indole acetic acid and indole butyric acid. Composition 2 collected by eluting with 5 mL 5% amonium methanol was used for the determination of paclobutrazol, Kinetin, 6-Benzylaminopurine. The clean-up procedures are designed according to different chemistry properties of these plant growth regulators. The results showed that after spiking of 0. 01-0. 1 mg / kg selected plant growth regulators, average recovery ranged from 70. 0% to 93. 2%and relative standard deviation were 5. 2% -12. 3% . Limit of quantification (LOQ S / N≥10) and limit of detection (LOD S / N≥3) were 0. 01-0. 025 mg / kg and 0. 003-0. 008 mg / kg respectively. The developed purification method is easy, fast and accurate, and can be applied to routine test of plant growth regulators in bean sprout.

We expressed recombinant single-stranded DNA-binding protein (r-SSBP) from Escherichia coli with the molecular weight of 24-kDa by using genetic engineering strategy, and demonstrated the single-stranded DNA (ssDNA)-binding activity of r-SSBP by electrophoretic mobility shift assay (EMSA). To further characterize r-SSBP, we studied the effects of r-SSBP on melting temperature (T(m)) of DNA. The results showed that r-SSBP could bind to ssDNA, and lower the T(m) of DNA, especially for single-base mismatched DNA. Therefore, r-SSBP significantly increased the T(m) difference between single-base mismatched DNA and perfect matched DNA. These results are very beneficial for single-nucleotide polymorphism detection. Moreover, we applied r-SSBP in high sensitive pyrosequencing system developed by our group. The results suggest that the r-SSBP decreased non-specific signals, corrected the proportion of signal peak height and improved the performance of pyrosequencing.

Objective:To explore the intervention effect of acceptance and commitment therapy on the psychological flexibility, self-compassion, anxiety and depression of the primary caregivers of patients with primary liver cancer, so as to provide reference for the clinical care of the primary caregivers of cancer patients.Methods:This was a prospective study. A total of 80 primary caregivers of patients with primary liver cancer treated in Tianyou Hospital Affiliated to Wuhan University of Science and Technology from July to December 2021 were selected as the observation objects, and they were randomly divided into the control group and the intervention group according to the random drawing method, with 40 cases in each group. The control group was given routine nursing measures, while the intervention group was given acceptance and commitment therapy on the basis of routine nursing. The intervention effect was evaluated by the Acceptance and Action Questionnaire-2nd Edition (AAQ-Ⅱ), Self-Compassion Scale Short-Form (SCS-SF) and Hospital Anxiety and Depression Scale (HADS) before the intervention, on the day of discharge, and one month after discharge.Results:Finally, 71 primary caregivers completed the intervention and follow-up, 36 in the control group and 35 in the intervention group. Before the intervention, there was no statistically significant difference in the scores of AAQ-Ⅱ, SCS-SF, Anxiety subscale of HADS(HADS-A) and Depression subscale of HADS(HADS-D) between the two groups ( P>0.05). The AAQ-Ⅱscores of the intervention group on the day of discharge and one month after discharge were (19.63±2.59), (19.12 ± 2.20) points, which were significantly lower than those of the control group (23.14 ± 2.49), (22.56 ± 2.40) points. The differences were statistically significant ( t=5.83, 6.25, both P<0.01). The SCS-SF scores of the intervention group on the day of discharge and one month after discharge were (39.34 ± 2.68), (39.89 ± 2.81) points, which were significantly higher than those of the control group (36.69 ± 3.08), (37.72 ± 2.41) points, the differences were statistically significant ( t=-3.86, -3.49, both P<0.01). The HADS-A/HADS-D scores of the intervention group on the day of discharge and one month after discharge were (9.31 ± 1.95), (9.09 ± 1.60) points and (8.80 ± 2.15), (8.54 ± 1.75) points,which were significantly lower than those of the control group(11.42 ± 1.50), (11.03 ± 1.70) points and (10.11 ± 1.92), (10.03 ± 1.84) points, the differences were statistically significant( t values were 2.71-5.10, all P<0.01). The scores of AAQ-Ⅱ, SCS-SF, HADS-A and HADS-D of the two groups were analyzed by repeated measures analysis of variance, and there were significant differences in time effect, inter-group effect and interaction effect ( F vaules were 3.42-37.90, all P<0.05). Conclusions:Acceptance and commitment therapy can improve the self-compassion and psychological flexibility, reduce anxiety and depression of the primary caregivers of patients with primary liver cancer.
