Background Health literacy is closely related to mental health, and improving health literacy has been shown to promote mental well-being. However, whether occupational stress among workers in mining and manufacturing is associated with their occupational health literacy remains inconclusive. Objective To study the levels of occupational health literacy and occupational stress among workers in three industrial sectors (metal ores mining, metal smelting, and manufacture of non-metallic mineral products) in Gansu Province, and to analyze the correlation between them. Methods Between May and December 2024, a stratified cluster random sampling method was employed to survey workers from 73 large, medium, and small and micro sized enterprises across the aforementioned industries in Gansu Province. Participants’ occupational health literacy and occupational stress levels were assessed. The LASSO regression model was applied to identifykey factors influencing occupational stress, and subsequently a multilevel random intercept mixed-effects logistic model was used to study factors influencing occupational stress and to explore the relationship between occupational health literacy and occupational stress. Results A total of 3611 workers across the three industries were surveyed, among whom 1031 (28.55%) experienced occupational stress. Workers with adequate occupational health literacy—whether assessed in terms of overall literacy or specific dimensions—demonstrated a significantly lower prevalence of occupational stress compared to those without adequate literacy (P<0.05). Through the LASSO regression analysis, it was found that the factors closely related to occupational stress were dimension one (occupational health legal knowledge), dimension two (basic knowledge of occupational health protection), and dimension four (healthy working methods and behaviors) of occupational health literacy, gender, average monthly income, and night shifts. The results from the three-level random intercept mixed-effects logistic regression model indicated that dimensions one (OR=0.69, 95%CI: 0.58, 0.82), two (OR=0.71, 95%CI: 0.58, 0.87), and four (OR=0.81, 95%CI: 0.67, 0.98) of occupational health literacy were negatively correlated with the risk of occupational stress. Workers with an average monthly income of 3001–≤5000, 5001–≤7000, and ≥7001 yuan reported occupational stress risks that were 61% (OR=0.61, 95%CI: 0.45, 0.81), 56% (OR=0.56, 95%CI: 0.41, 0.78), and 36% (OR=0.36, 95%CI: 0.24, 0.53) of those with an average monthly income ≤3000 yuan, respectively. Male workers (OR=1.66, 95%CI: 1.32, 2.10) and those on night shifts (OR=2.29, 95%CI: 1.90, 2.76) had a higher risk of occupational stress. The random effects variance showed that the intraclass correlation coefficient was 0.12. Conclusion There is a negative correlation between occupational stress and occupational health literacy among workers in mining and manufacturing. Being male, having a low income, and working night shifts are risk factors affecting workers' occupational stress. It is recommended to focus on these groups of workers and incorporate occupational health literacy into workplace mental health promotion.

BACKGROUND:Obesity negatively affects dynamic balance during walking,and crossing barriers is a more routine functional activity that requires more stability in controlling body posture. OBJECTIVE:To investigate the differences in dynamic stability between obese and average males,and to assess the balance ability of obese males using a relatively more challenging obstacle crossing. METHODS:A total of 24 male youths(12 each in the obese and normal groups)were recruited to complete the tests of walking on level ground and crossing obstacles of different heights(4 cm,11 cm,15 cm)in random order.Kinematic and dynamic data were collected using the Qualisys motion capture system and Kistler force stage.Statistical analysis was performed using two-factor(2 groups * 4 movement types)repeated measures analysis of variance. RESULTS AND CONCLUSION:The obese group had a lower step speed than the normal group(P<0.05),the proportion of the first single support period decreased and the proportion of the second double support period increased when crossing the 11 cm versus 15 cm hurdles(P<0.05).When walking on level ground,the margin of stability in the internal and external directions in the normal group was greater than that of the obese group(P<0.05).When crossing the 4 cm hurdles,the margin of stability in the obese group was less than that in the normal group(P<0.05).When crossing the 11 cm hurdles,there was no significant difference between the two groups in the anterior-posterior direction(P>0.05),while there was a significant difference in the internal-external direction(P<0.05).When crossing the 15 cm hurdles,the margin of stability in the obese group was lower than that in the normal group(P<0.05).Overall,obesity decreases the body's ability to control the body,reduces dynamic stability during crossing the barrier,and increases the risk of falls compared with the general population.In addition,compared with level ground walking,the decrease in the dynamic stability when crossing barriers is more significant in the obese group than the general population.

Objective To investigate the efficacy and safety of Linaclotide combined with Simethicone oil and compound polyethylene glycol electrolyte(PEG)for cleansing effect of bowel in patients with constipation.Methods A prospective randomized controlled trial was designed and implemented by single blind method.383 patients with constipation who underwent colonoscopy from April 2023 to August 2024 were enrolled and randomly divided into routine group(128 cases),experimental group A(128 cases)and experimental group B(127 cases).Routine group treated with 3 L PEG,experimental group A treated with 290 μg Linaclotide+2 L PEG and experimental group B treated with 290 μg Linaclotide+30 mL Simethicone+2 L PEG.Bowel preparation effect[Boston bowel preparation scale(BBPS)scores and foaming removal effect],lesion detection rate,first defecation interval,frequency of defecation,the success rate of cecal intubation,the insertion time of colonoscopy,the withdrawal time of colonoscopy,incidence of adverse reactions and willingness to repeat examination of the three groups were compared.Results No statistically significant differences were observed in the BBPS scores among the three groups(P>0.05);The foaming removal effect score in experimental group B was significantly lower than that in routine group and experimental group A,the difference was statistically significant(P<0.05);The total lesion detection rate and polyps detection rate of experimental group B were significantly higher than those of routine group and experimental group A,the differences were statistically significant(P<0.05).The first defecation interval of the routine group was significantly longer than that of experimental group A and experimental group B,the difference was statistically significant(P<0.05);The frequency of defecation was compared among the three groups,and the difference was no statistically significant(P>0.05).The success rate of cecal intubation in the three groups was 100.0%,and the insertion time of colonoscopy was similar,the differences were not statistically significant(P>0.05);The withdrawal time of colonoscopy in experimental group B was significantly shorter than that in routine group and experimental group A,the difference was statistically significant(P<0.05).The incidence of abdominal distension and total adverse reactions in the routine group were higher than those in experimental group A and experimental group B,the differences were statistically significant(P<0.05);The willingness to repeat examination rate of the routine group was significantly lower than that of experimental group A and experimental group B,the differences were statistically significant(P<0.05).Conclusion 290 μg Linaclotide combined with 30 mL Simethicone and 2 L PEG solution regimen has advantages in intestinal preparation for patients with constipation,and can achieve better intestinal cleaning effect than 3 L PEG solution and 290 μg linalopeptide+2 L PEG solution regimen,with higher safety and willingness to repeat examination.It can be recommended for bowel preparation for patients with constipation.

Objective:To explore the feasibility and effectiveness of full free-breathing cardiac magnetic resonance (CMR) in clinical practice.Methods:The study prospectively included patients who underwent full free-breathing CMR and traditional breath-holding cine imaging between June 1 and June 30, 2024. An analysis and comparison were conducted on the image acquisition time, image quality, and left ventricular function parameters under two scanning methods, including left ventricular ejection fraction (LVEF), left ventricular cardiac output (LVCO),left ventricular end diastolic volume (LVEDV), left ventricular end diastolic volume index (LVEDVI), left ventricular end systolic volume (LVESV), left ventricular end systolic volume index (LVESVI), left ventricular stroke volume (LVSV), and left ventricular mass (LVM). In addition, the study conducted both quantitative and qualitative analyses of other sequences in full free-breathing CMR, including T 1 mapping, T 2 mapping, flow imaging, and late gadolinium enhancement (LGE). Group comparisons were performed using the Wilcoxon signed-rank test or paired t-test. Consistency assessments included Bland-Altman analysis, intraclass correlation coefficient ( ICC), and linear regression analysis. Results:Totally, 150 patients were recruited into the study. The average acquisition time of full free-breathing CMR was (22.1±3.1) min, with an average short axis cine sequence examination time of (2.7±0.4) min; The average acquisition time of short axis images in a breath-holding state was (4.9±1.4) min, which was significantly longer than the cine scan in the free-breathing state ( P0.001). The cine and LGE images quality scores obtained from full free-breathing CMR were 4 (4, 4) points and 5 (4, 5) points, respectively, while the cine image quality score obtained in a breath-holding state was 5 (4, 5) points. Compared with traditional breath-hold CMR, free-breathing CMR measurements showed slightly higher LVESV, and LVESVI, while LVEDV, LVEDVI, LVSV, LVCO, LVEF, and LVM were slightly lower, except for LVSV and LVCO, which showed no statistically significant difference, the differences in other cardiac function parameters were statistically significant ( P0.05). However, the two methods demonstrated good consistency( ICC0.947) and correlation (0.808 r0.993, P0.001). The Bland-Altman analysis showed that the bias for all cardiac function parameters was within 8.0%. The Native T 1 and T 2 values for free-breathing CMR were (1 277.5±57.0) ms and 40.1 (38.5, 41.4) ms, respectively, and the results of flow imaging and echocardiography were basically consistent. Conclusions:Free-breathing CMR is feasible and effective in clinical practice, showing a high level of consistency with left ventricular functional parameters obtained from traditional breath-hold scanning. It significantly shortens examination time and holds great clinical value for the promotion and widespread use of CMR.

All patients were treated with rhGH. The growth parameters, growth factors, glucose metabolism and lipid metabolism indexes were collected and calculated before treatment and at 3, 6, 12, 18 and 24 months after treatment, the influence of sex and age on these indexes and the correlations between these indicators and height growth rate were analyzed. Independent-sample t-test was used to compare two groups with normal distribution, one-way ANOVA was used to compare multiple groups, and repeated measures ANOVA was used to compare the mean of each time point within groups. The nonparametric rank sum test was used for the comparison of non-normal distribution measurement data. Pearson correlation analysis was used to analyze the correlation between HGV and each index.Results:A total of 80 children were enrolled, 39 boys and 41 girls. Grouped by age, there were 20 in the 3.00-5.99 age group, 41 in the 6.00-9.99 age group, and 19 in the ≥10.00 age group. All patients after 24 months of treatment had a higher height ((135.13±13.17) cm), HtSDS (-0.73 (-1.04, -0.41)), body weight (29.25 (23.13, 35.00) kg), weight standard deviation score (WtSDS) (-0.44 (-1.03, 0.03)), and body mass index (BMI) (15.99 (14.90,16.92) kg/m 2) compared to before treatment ((115.44±12.87) cm, -2.11 (-2.57, -2.03), 20.00 (16.00,25.00) kg, -1.48 (-2.12, -0.89) and 15.30 (14.45, 16.21) kg/m 2) all increased, and the differences were statistically significant (all P<0.05). The increase in HtSDS in the group aged 3.00-5.99 (1.74±0.29) was higher than that in the group aged 6.00-9.99 (1.57±0.33) and ≥10.00 (1.39±0.45), and the difference was statistically significant ( F=4.84, P=0.010). All patients showed an increase in insulin-like growth factor 1 (IGF-1) (329.50 (268.00, 417.25) μg/L) and insulin-like growth factor binding globulin 3 (IGFBP-3) (6.27 (5.50,6.95) mg/L) after 24 months of treatment compared to before treatment (131.50 (96.48,177.25) μg/L, 4.07 (3.60,4.88) mg/L), with statistical significance (all P<0.05). After treatment for 3 months, 6 months, 12 months, 18 months, and 24 months, children aged ≥ 10.00 years old with IGF-1 (353.00 (221.00, 493.00), (414.84±147.91), 441.00 (287.00, 578.00), (421.68±138.30), 376.00 (290.00, 581.00) μg/L) were higher than these in 3.00-5.99 years old group (181.00 (151.25, 237.75), (216.30±68.48), 239.50 (216.75, 325.00), (284.30±89.12), 293.00 (245.25, 343.75)) μg/L and 6.00-9.99 age group (253.00 (193.50, 345.50), (294.59±90.37), 284.00 (217.50, 377.50), (325.76±90.04), 345.00 (265.00, 431.00) μg/L, the difference was statistically significant (all P<0.05). At 3 months, 6 months, 12 months, and 18 months of treatment, IGFBP-3 levels were observed in children aged ≥ 10.00 years old (6.15 (5.52, 6.46), (6.56±1.26), (6.78±1.33), (6.78±1.38) mg/L) higher than 3.00-5.99 years old group (4.69 (4.43,5.11), (5.18±0.63), (5.61±0.84), (6.08±1.00) mg/L) and 6.00-9.99 age group (5.51 (4.76, 6.35), (5.61±0.81), (5.72±0.78), (6.03±0.80) mg/L, the difference was statistically significant (all P<0.05). All children with HbA1C (5.40 (5.20, 5.58)%), fasting blood glucose (5.06 (4.76, 5.24) mmol/L), triglycerides (0.67 (0.53, 1.02) mmol/L), TyG index (2.24±0.48), and triglyceride/HDL-C ratio (1.05 (0.73, 1.50)) after 24 months of treatment compared to before treatment (5.10 (5.00, 5.28)%, 4.78 (4.51, 5.09) mmol/L, 0.57 (0.47, 0.72) mmol/L, (1.92±0.36), 0.86 (0.65, 1.08). The level of cholesterol increased, and the total cholesterol (3.74 (3.39, 4.31) mmol/L) decreased compared to before treatment (3.95(3.64, 4.54) mmol/L), with statistical significance (all P<0.05). Female patients had higher levels of triglycerides (0.79 (0.59, 1.09) mmol/L) and TyG index (2.31±0.49) than male patients (0.66 (0.53,0.89) mmol/L, (2.16±0.46)) after 18 months of treatment. The triglyceride/HDL-C at 12 months (1.10(0.67, 1.93)), 18 months (1.16(0.83, 1.68)), and 24 months (1.26 (0.79, 1.81)) of treatment ratio was also higher than male patients (0.76 (0.61, 1.09), 0.90 (0.72, 1.08), 0.98 (0.66, 1.30)). Female HDL-C levels at 18 months (1.52 (1.29,1.75) mmol/L) and 24 months (1.45(1.29,1.76) mmol/L) of treatment were significantly lower in males (1.72 (1.45, 1.84), 1.59 (1.43, 1.92) mmol/L) with statistical significance (all P<0.05). HGV was positively correlated with IGF-1 at 12 months ( r=0.243, P=0.030) , 18 months ( r=0.277, P=0.013) and 24 months ( r=0.289, P=0.009), and it was positively correlated with IGFBP-3 at 18 months ( r=0.242, P=0.030) and 24 months ( r=0.236, P=0.035), but it was negatively correlated with HDL-C at 18 months ( r=-0.331, P=0.003) and 24 months ( r=-0.281, P=0.012). Conclusions:RhGH can obviously improve HtSDS and WtSDS in GHD children. Growth factors, glucose metabolism and lipid metabolism should be monitored during the treatment. Especially for female patients (≥10.00 years old), we should closely monitor the indexes of glucose and lipid metabolism in order to avoid metabolic diseases.

Objective:To investigate the affection of high mobility group nucleosome-binding protein 5(HMGN5) gene in the hepatocellular cancer tissue and HepG2 cell and its function in the growth of HepG2 cell.Methods:70 Patients with hepatocellular carcinoma who under-went surgical resection and were confirmed by postoperative pathology in Sunshine Union Hospital of Weifang City from January 2017 to June 2020 were selected. Their clinical and pathological data, surgical resection of liver cancer tissue and adjacent normal liver tissue were collected, their survival time were also recorded. The contents of HMGN5 protein in the hepatocellular cancer tissues and adjacent normal liver tissues of 70 patients were detected by immunohistochemistry. Compare the expression of HMGN5 protein in liver cancer tissue and normal liver tissue and the positive expression rate of HMGN5 protein in liver cancer tissues of hepatocellular carcinoma patients with different clinical characteristics, to analyze the relationship between HMGN5 expression and prognosis of patients with hepatocellular carcinoma.The mRNA contents of HMGN5 gene in HepG2 cells and HL-7702 cells were determined by quantitative real time polymerase chain reaction(qRT-PCR) method. After transfectHepG2 cells with HMGN5 shRNA, the proliferation ability of HepG2 cells were evaluated by cell proliferation assay and the cell apoptosis was analyzed by flow cytometry. Measurement data with normal distribution were expressed as ±s, two independent samples t test was used for comparison between groups. Counting data was expressed as n(%), χ2 test was used for comparison between groups. Survival analysis of patients was performed by Kaplan-Meier method. Results:Immunohistochemical tests showed that HMGN5 staining is strong in liver cancer tissue, but weak in normal liver tissue. HMGN5 protein expression was positive in 48 of 70 patients with hepatocellular carcinoma. The positive expression rate of HMGN5 protein in hepatocellular carcinoma tissues of patients with pathological grade 3+4 and clinical stage Ⅲ+Ⅳ was higher than that of patients with grade 1+2 and stage Ⅰ+Ⅱ, respectively. There was no significant difference in cumulative survival rate between HMGN5 positive expression group and HMGN5 negative expression group ( χ2=3.81, P=0.051). The results of qRT-PCR showed that the expression level of HMGN5 mRNA in hepatoma HepG2 cells was higher than that in normal liver HL-7702 cells [(4.51±0.45) vs (1.35±0.27), the difference was statistically significant ( t=10.43, P=<0.001). After 24, 48 and 72h of the HMGN5 gene was knockout, the survival rate of HepG2 hepatoma cells was lower than that of HL-7702 hepatoma cells (all P<0.05) and the apoptosis rate of hepatoma HepG2 cells was higher than that of liver HL-7702 cells [(18.63±1.76)%vs(1.81±0.21)%] ,the difference was statistically significant ( t=16.44, P<0.001). Conclusions:HMGN5 genes and proteins are highly expressed in the hepatocellular cancer tissues and HepG2 cells. HMGN5 gene plays an important role in the growth of hepatocellular cancer and can be used as a potential target of treatment for hepatocellular cancer.

Objective:To explore the applied effectiveness of the Skin and/or tissue,Education,Cooperation,Understanding,Report and Evaluate (SECURE) nursing pathway based on action research method in the prevention process of medical device-related pressure injuries (MDRPI) of patients in the Intensive Care Unit (ICU). Methods:The SECURE nursing pathway based on action research method included the establishment of a skin care team to identify problems,and the formulation of conducting intervention plan,and the development of targeting nursing interventions to prevent the occurrence of MDRPI. A total of 84 patients hospitalized in the ICU of Hebei General Hospital from March 2022 to March 2023 were selected,and they were randomly divided into a control group and an observation group,with 42 patients in each group. The control group implemented routine method to prevent MDRPI during ICU treatment,while the observation group implemented SECURE nursing pathway based on action research method to conduct prevention. The MDRPI incidence,the quality scores of ICU nursing,the scores of the Short Form Health Survey-36 (SF-36) of patients,the assessment of the improvement of MDRPI patients,and the satisfaction of patients for nursing care were compared between the two groups. Results:The MDRPI incidence during ICU treatment in the observation group was 4.76％ (2/42),which was significantly lower than that in the control group,with a statistically significant difference (x2=11.052,P<0.05). The average scores for device usage,prevention assessment,positioning management and preventive nursing after nursing intervention in the observation group were respectively (88.45±2.05),(89.36±2.11),(89.25±2.15) and (91.45±2.25),all of which were significantly higher than those in the control group,with statistically significant differences (t=11.425,12.052,10.052,13.478,P<0.05). After nursing intervention,the average scores for physical function,social function,psychological function and material life as the SF-36 scale in the observation group were (85.47±2.05),(86.48±2.05),(88.46±2.15) and (90.25±2.44),respectively,which were respectively higher than those in the control group,with statistically significant differences (t=12.414,11.045,10.252,10.478,P<0.05). The occurrence time,improvement time of wound and ICU treatment time of presenting MDRPI patients in the observation group were respectively (4.05±0.54) days,(3.45±0.15) days,and (8.12±2.14) days. Compared to the control group,the occurrence time of the observation group was longer,while both the improvement time of wound and ICU treatment time of the observation group were shorter,with statistically significant differences (t=8.485,10.012,13.001,P<0.05). The satisfaction degree of nursing care of patients in the observation group was 95.24％ (40/42),which was significantly higher than that in the control group (x2=12.054,P<0.05). Conclusion:The SECURE nursing pathway based on action research method,which prevents MDRPI of ICU patients,can reduce the MDRPI incidence rate of ICU patients,and enhance the work quality of nursing care for MDRPI. It is helpful to the recovery of ICU patients,which can also shorten the treatment time of ICU patients.
