Objective:To explore the impact of noise and dust exposure in the mechanical manufacturing industry on the risk of hypertension and abnormal electrocardiogram in workers, and their combined effects, in order to provide support for the prevention and treatment of occupational related diseases among workers.Methods:In January 2024, A convenience sampling method was used to study 2802 on-the-job workers who underwent occupational health check-ups from January 2023 to December 2023 at a machinery manufacturing enterprise in Baotou, Inner Mongolia. Blood pressure and electrocardiogram results were analyzed in the noise group, dust group, dust noise group and control group according to the exposure factors. For count data, the chi-square test was employed to analyze differences among groups. Additionally, a binary logistic regression model was utilized to assess the impact of dust and noise exposure on the prevalence of hypertension and electrocardiogram abnormalities.Results:The stratified analysis results showed that the differences in hypertension prevalence among the four groups were statistically significant ( P<0.001) in males, age groups >30-40 years, >40-50 years, >50 years, different exposure durations, and different enterprise sizes. For ECG abnormalities, significant differences were observed among the four groups ( P<0.001) in males, the age group >30-40 years, different enterprise sizes, and those with exposure durations ≤15 years. The trend test for hypertension prevalence across different age groups revealed that as age increased, the prevalence of hypertension showed an upward trend in the noise-exposed group, dust-exposed group, and combined dust-noise-exposed group ( χ2=10.76, 4.25, 6.60, P<0.001, 0.039, 0.010) . Binary regression model analyses revealed that the the risk of hypertension in the noise group, dust group and dust noise group was 2.63 times ( OR=2.63, 95% CI: 1.89~3.67, P<0.001) , 2.36 times ( OR=2.36, 95% CI: 1.76~3.16, P<0.001) and 2.69 times ( OR=2.69, 95% CI: 2.14~3.38, P<0.001) . Using ECG abnormalities as the dependent variable and incorporating the statistically significant variables from Table 1 as independent variables into the binary logistic regression model, the results showed no statistically significant differences in the risk of ECG abnormalities in the dust-exposed, noise-exposed, and combined dust-noise-exposed groups compared to the control group ( P> 0.05) . Conclusion:Combined exposure to dust and noise increases the risk of hypertension in workers and has a combined effect.

Objective To develop the Evidence-Based Health Care Related Competence Assessment Scale for Health Professionals(hereinafter referred to as the Scale),and to test its validity and reliability.Methods Based on the JBI evidence-based health care model as the theoretical framework,the initial items of the Scale were formed by reviewing the literature.Through the discussion of the research group,two rounds of Delphi expert consultation and pre-inspection,the items of the Scale were optimized.The convenience sam-pling method was adopted to extract 928 health professionals as the research subjects.The Scale conducted the validity and reliability testing.Results The Scale included the four dimensions of evidence generation,evi-dence synthesis,evidence transfer and evidence implementation,including 47 entries in total.The cumulative variance contribution rate was 59.08%.The confirmatory factor analysis results indicated that the model had good fitness.The convergent validity of all dimensions reached the standard,and the distinguishing validity was good.Finally,the Cronbach's α coefficient of the Scale was 0.971,and the split-half reliability was 0.928.Conclusion The developed Scale possesses good reliability and validity,which can be used to evaluate the competence of health professionals carrying the evidence-based healthcare related link works.

Objective To analyze the clinical characteristics,drug sensitivity,and prognostic risk factors of patients with candidemia at our hospital,for providing evidence for rational drug use and improving prognosis.Methods A total of 181 patients with candidemia who were admitted to our hospital between January 2020 and December 2022 were selected for this study.Basic data,drug susceptibility test results,and clinical information were collected and analyzed.Patients were divided into two groups:a favorable prognosis group and a poor prognosis group;their prognostic risk factors were analyzed using univariate and binary logistic analyses.Results Candidemia was diagnosed from 181 Candida strains,including Candida parapsilosis(88 strains,48.62％),Candida albicans(34 strains,18.78％),Candida tropicalis(29 strains,16.02％),and Candida glabrata(17 strains,9.39％).Patients with candidemia were mainly diagnosed during general surgery(51.93％),intensive care unit(16.02％),and emergency department(9.94％).Univariate and binary logistic analyses showed that use of hormone and(or)immunosuppressive agents(OR=4.787),mechanical ventilation for more than 96 h(OR=4.558),renal insuffi-ciency(OR=4.426),and intrapulmonary infection(OR=4.228)were important independent risk factors.The highest detection rate of can-didemia in our hospital was for Candida parapsilosis.With the exception of Candida tropicalis,which was less sensitive to voriconazole,all other strains were sensitive to azole drugs.In conclusion,hormone and(or)immunosuppressive agents,mechanical ventilation for more than 96 h,renal insufficiency,and intrapulmonary infection are independent risk factors for poor prognosis in patients with candidemia.

Objective:To investigate the clinical efficacy of pentoxifylline sequential therapy combined with rasagiline and levodopa in the treatment of elderly patients with symptoms of Parkinson disease (PD), and the influence on hemorheology and serum Toll-like receptor 4 (TLR4) signaling pathway downstream related inflammatory factors.Methods:A prospective study method was used to select 90 elderly patients with PD with fluctuating symptoms who were admitted to the Eighth People′s Hospital of Hebei Province from June 2021 to October 2022 as research objects. The patients were divided into observation group and control group with 45 cases in each group according to random number table method. The observation group was treated with pentoxifylline sequential therapy combined with rasagiline and levodopa. The control group was treated with rasagiline combined with levodopa. The clinical efficacy of the two groups was compared. The unified Parkinson disease rating scale (UPDRS), Montreal cognitive assessment scale (MoCA), Berg balance scale (BBS) and 39-item Parkinson disease quality of life questionnaire (PDQ-39) were scored before and after treatment. Hemorheology indexes and serum levels of related inflammatory factors downstream of TLR4 signaling pathway, including whole blood high viscosity (HBV), whole blood low shear viscosity (LBV), plasma viscosity (PV), fibrinogen (FIB); TLR4, interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF) -α, were detected before and after treatment in both groups. The adverse reactions of the two groups were compared.Results:The total effective rate in observation group was significantly higher than that in control group: 93.33% (42/45) vs. 77.78% (35/45), and there was statistical difference ( P<0.05). After treatment, the UPDRS mental activity and emotional disorders, daily living ability, motor function, motor complications scores and PDQ-39 score of the two groups were significantly lower than before treatment, the MoCA and BBS scores were significantly higher than before treatment, and the improvement was more significant in the observation group, there were statistical differences ( P<0.05). After treatment, HBV, LBV, PV and FIB in the observation group were significantly decreased compared with those before treatment: (6.52 ± 0.92) mPa·s vs. (7.25 ± 1.24) mPa·s, (11.45 ± 1.24) mPa·s vs. (14.13 ± 1.64) mPa·s, (1.55 ± 0.17) mPa·s vs. (1.88 ± 0.22) mPa·s, (3.25 ± 0.47) g/L vs. (3.82 ± 0.52) g/L, and there were statistical differences ( P<0.05). There were no significant differences in hemorheology indexes of control group before and after treatment ( P>0.05). After treatment, serum levels of TLR4, IL-1β, IL-6 and TNF-α in both groups were significantly decreased compared with those before treatment, and the indexes in observation group were significantly lower than those in control group: (2.07 ± 0.18) ng/L vs. (2.58 ± 0.21) ng/L, (1.42 ± 0.17) ng/L vs. (2.28 ± 0.25) ng/L, (1.56 ± 0.22) ng/L vs. (2.42 ± 0.28) ng/L, (46.31 ± 3.17) ng/L vs. (54.34 ± 3.65) ng/L, and the differences were statistically significant ( P<0.05). There was no significant difference in the incidence of adverse reactions between the two groups ( P>0.05). Conclusions:Pentoxifylline sequential therapy combined with rasagiline and levodopa can effectively improve the hemorheology of elderly patients with PD accompanied by symptom fluctuations, reduce the levels of related inflammatory factors downstream of serum TLR4 signaling pathway, and improve clinical efficacy.

Gastric cancer is the most prevalent gastrointestinal tumor in China， threatening the life and health of patients. Surgery is one of the available therapies， which， however， induces postoperative gastrointestinal dysfunction （PGD） and other common complications. The pathogenesis of PGD is still unclear and no efficient targeted drug is available. In addition， the limited treatment measures fail to effectively improve gastrointestinal function. As a result， patients generally suffer from low quality of life and poor prognosis. In Chinese medicine， PGD belongs to the categories of "vomiting"， "stuffiness and fullness"， "regurgitation"， "abdominal distension"， "intestinal impediment"， and "intestinal accumulation". In recent years， there has been an explosion of research on the PGD of gastric cancer in Chinese medicine， and many research results have been obtained. On this basis， this study introduced PGD in modern medicine， and causes and pathogenesis， syndrome differentiation-based treatment， and clinical studies of PGD. It was found that diverse internal and external treatments are available in Chinese medicine for PGD such as internal use of Chinese medicine， Chinese medicine enema， auricular point seed-embedding， acupuncture， and moxibustion， which feature ease of implementation， small side effects， definite efficacy， and significant effect in combination with other therapies. This paper summarized the ideas and measures for treatment of PGD of gastric cancer by Chinese medicine， the research outcomes， limitations， and research directions， which can serve as a reference for further research on treatment of PGD of gastric cancer by Chinese medicine.

Objective:To investigate the value of arterial enhancement fraction in the diagnosis of hepatocellular carcinoma in patients with liver cirrhosis.Methods:The clinical data of 80 liver cirrhosis patients with pathologically and clinically confirmed hepatocellular carcinoma who received treatment from April 2019 to April 2021 in Benxi Central Hospital were retrospectively analyzed. The data from phase III enhanced CT scans were input into the PACS system. Two physicians independently measured the CT values of hepatocellular carcinoma and liver cirrhosis using a double blind method. The AEF values were calculated. According to Child-Pugh classification, the severity of liver disease was divided into class A ( n = 33), class B ( n = 29), and class C ( n = 18). The AEF value of hepatocellular carcinoma was compared with that of liver cirrhosis in the same group. The AEF value of liver cirrhosis was compared between different classes of liver cirrhosis. The AEF value of hepatocellular carcinoma was compared between different classes of liver cirrhosis. Results:The inter-observer agreement of mean AEF values was high ( ICC = 0.95, 95% CI = 0.93-0.97). The mean AEF value of hepatocellular carcinoma was (54.79 ± 10.95)% for patients with class A liver cirrhosis, (54.90 ± 9.99)% for patients with class B liver cirrhosis, and (54.16 ± 7.19)% for patients with class C liver cirrhosis. The mean AEF value of liver cirrhosis was (39.94 ± 6.50)% for patients with class A liver cirrhosis, (44.97 ± 4.31)% for patients with class B liver cirrhosis, and (54.11 ± 4.63)% for patients with class C liver cirrhosis. In patients with class A and class B liver cirrhosis, the AEF value of hepatocellular carcinoma was significantly higher than that of liver cirrhosis (class A: t = 5.18, P = 0.001; class B: t = 3.94, P < 0.001). There was no significant difference in the AEF value between hepatocellular carcinoma and liver cirrhosis in patients with class C liver cirrhosis ( t = 0.02, P = 0.982). Conclusion:The AEF value has an important reference value for the differential diagnosis of hepatocellular carcinoma from liver cirrhosis.

A 34-year-old male patient received a subcutaneous injection of 300 mg of secukinumab once a week for 5 times, subsequently 300 mg once every 4 weeks for 3 times because of psoriasis. Then the patient developed bloody purulent stool. Electronic colonoscopy revealed diffuse mucosal congestion and edema in the sigmoid colon at a distance of 25 cm from the anus. The pathological examination results of tissue biopsy showed severe chronic inflammation, erosion, and shallow ulcer formationin the sigmoid colon. Inflammatory bowel disease caused by secukinumab was considered. Then the drug was stopped, and mesalazine enema solution 60 g once daily was given. After half a month of treatment, the patient′s bloody purulent stool was improved significantly, and after 2 months, it disappeared. Electronic colonoscopy showed that the mucosa of the sigmoid colon was rough, granular, and scattered with small patches of bleeding at a distance of 20 cm to 25 cm from the anus, which was diagnosed as having ulcerative colitis (in remission). Mesalazine enema was discontinued and changed to mesalazine suppository 0.5 g once daily.
