Objective:To understand the influence of unhealthy lifestyle on diabetic dyslipidemia and the key influencing factors in occupational population and provided scientific evidence for the prevention of diabetic dyslipidemia.Methods:Based on baseline data and follow-up data of Southwest Occupational Population Cohort from China Railway Chengdu Group Co., Ltd. during 2021. Diabetic dyslipidemia was defined as diabetes plus one or more forms of dyslipidemia, and unhealthy lifestyle factors included smoking, alcohol consumption, unhealthy dietary patterns, low physical activity, and abnormal BMI. Multivariate logistic regression model was used to analyze the relationship between unhealthy lifestyle scores and diabetic dyslipidemia, network analysis was used to find and explore the key lifestyles influencing glycolipid metabolism.Results:A total of 25 631 subjects were included. People with unhealthy lifestyle score 2 and 3 were 1.93 (95% CI: 1.31-2.86) times and 2.37 (95% CI: 1.60-3.50) times more likely to have diabetes with ≥1 forms of dyslipidemia than those with scores of 0; People with unhealthy lifestyle score 1, 2 and 3 were 1.98 (95% CI: 1.08-3.61) times, 2.87 (95% CI: 1.60-5.14) times and 3.95 (95% CI: 2.22-7.06) times more likely to have diabetes with ≥2 forms of dyslipidemia than those with score 0. Network analysis found that abnormal BMI and HDL-C were the "bridge nodes" that link unhealthy lifestyles with diabetic dyslipidemia. Conclusion:The higher the score of unhealthy lifestyle, the higher the risk for diabetic dyslipidemia, abnormal BMI and HDL-C are key factors influencing the association between unhealthy lifestyle and diabetic dyslipidemia.

Objective:To understand the relationship between unhealthy lifestyle and hyperuricemia, as well as the modification effects of hypertension and dyslipidemia in occupational population and provide a theoretical basis for the prevention of hyperuricemia.Methods:A cross-sectional survey design was adopted, based on baseline data from the Southwest Occupational Population Cohort from China Railway Chengdu Group Co., Ltd., which included the population in 28 prefectures from Sichuan Province and Guizhou Province, and 33 districts (counties) from Chongqing Municipality between October and December 2021. This study collected the information about the demographics characteristics, lifestyles, and prevalence of chronic non-communicable diseases of the study subjects through questionnaire, physical measurement and laboratory biochemical test. The unhealthy lifestyle score was scored based on smoking, alcohol consumption, dietary patterns, physical activity, and low weight or overweight, with higher scores being associated with more unhealthy lifestyles. The multivariate logistic regression model was used to analyze the relationship between unhealthy lifestyle score, smoking, alcohol consumption, other factors and hyperuricemia, and the stratified analysis was used to explore the modification effect of hypertension and other diseases on the relationship between unhealthy lifestyle and hyperuricemia.Results:A total of 11 748 participants were included in this study, the prevalence of hyperuricemia was 34.4%. Multivariate logistic regression model showed that current/previous smoking, current/previous alcohol consumption and BMI abnormality were risk factors for hyperuricemia, and the unhealthy lifestyle score showed a "cumulative" effect on the risk for hyperuricemia, with higher score increasing the risk of hyperuricemia, and the OR increased from 1.64 (95% CI: 1.34-2.00) to 2.89 (95% CI: 2.39-3.50). Stratified analysis showed that unhealthy lifestyles had a greater impact on the risk for hyperuricemia in people with hypertension and dyslipidemia. Conclusions:The coexistence of multiple unhealthy lifestyles might increase the risk of hyperuricemia, and this effect was stronger in participants with hypertension and dyslipidemia. Timely correction of unhealthy lifestyles, and control of hypertension and dyslipidemia might reduce the risk for hyperuricemia.

Objective:To analyze the detection strategy and basic detection situation of markers of infectious diseases transmitted by transfusion in blood testing laboratories of blood stations in China.Methods:Based on the data of practice comparison working party of Blood Stations in Mainland of China from 2017 to 2021, the data on the testing strategies and the basic detection information of the markers for the transmission of infectious diseases through transfusion in the member laboratories of the practice comparison working party of Blood Stations in Mainland of China from 2017 to 2021 were collected, and the situation of the selection for testing markers, testing strategy and the testing method and other relevant aspects were sorted out and analyzed by charts.Results:The selection of the testing markers was consistent, but HTLV testing item was added in some member laboratories. The detection strategy of using two ELISA reagents and one nucleic acid testing (NAT) reagent simultaneously was adopted in 47 member blood stations; 3) NAT method was dominated by mini pool-NAT in member laboratories. The number of members adopting mini-pools of 8 (MP8)-NAT decreased from 17 in 2017 to 14 in 2021, while the number of members adopting mini-pools of 6 (MP6)-NAT increased from 13 in 2017 to 22 in 2021; Roche NAT system accounted for the largest proportion.Conclusions:In order to ensure blood safety and avoid missing detection, the blood stations still adopt the detection strategy of using two ELISA reagents and one nucleic acid testing (NAT) reagent simultaneously; Meanwhile, in order to increase the NAT positive rate, the proportion of mini pool-NAT mainly decreased year by year despite its dominating role, while the proportion of individual donation-NAT increased year by year; NAT method is transiting from mini-pools of 8 (MP8) to mini-pools of 6 (MP6); The proportion of imported NAT system used in NAT laboratory is relatively large.

Ganoderma lingzhi is a well-known source of natural fungal medicines which has been given for the treatment of several diseases. China is one of the major commercial producers of Ganoderma mushroom worldwide. However, with the expansion of the commercial cultivation, the occurrence of the fungal diseases on G. lingzhi has also been increased. The green mold disease symptoms were observed in the cultivation base of G. lingzhi in Zuojia Town, Jilin City, Jilin Province, China, causing the basidiomes to be rotten and withered, and the green mycelium layer generated gradually. The pathogenicity tests showed the same symptoms as appeared naturally in Zuojia mushroom base. Morphology characters revealed conidia green, ellipsoid, globose, 2.56–4.83 × 2.09–4.22 μm, length-width ratio was 1.1–1.2 (n = 10). Conidiophores trichoderma-like, often asymmetry, branches solitary, paired or in whorls of 3 phialides formed solitary, paired or in whorl, variable in shape, lageniform, sometimes ampulliform or subulate. While using molecular methodology, comparing with the sequences of Trichoderma hengshanicum from GenBank, the analyzed sequence showed 97.32% homology with the RPB2 sequences, 100% with the TEF1-α sequences. A fungus isolated from the diseased tissues was identified based on morphology and molecular studies as T. hengshanicum. This is the first report of T. hengshanicum causing the green mold disease of G. lingzhi in China.

Objective: Attentional biases toward emotional scenes may represent vulnerability and maintenance factors in depression. Antidepressant therapy may improve cognitive function and reduce depression, and is considered as the mechanism of action of antidepressants. Therefore, we conducted an eye-tracking test to examine whether selective serotonin re-uptake inhibitor (SSRI) antidepressants can reduce negative attentional biases and elicit clinical responses in depression. Methods: Twenty first-episode depressive patients freely viewed three types of pictures that depicted different emotional scenes (i.e., positive-control, neutral-control, and negative-control) for 4,000 ms while their eye movements were monitored. The attentional bias to different emotional scenes was assessed before and after eight weeks of SSRI treatment using the eye-tracking method. The control group included a group of healthy individuals. Results: The results revealed that first-episode depressive patients oriented their gaze more frequently to negative images and less to happy images, compared to controls. Importantly, the attentional bias in depressive patients was regulated after eight weeks of SSRI treatment. Patients showed an increased tendency to fixate on positive images and a decreased tendency to focus on negative images. Conclusion This suggests that SSRI antidepressants decrease vulnerability to negative images, while having an effect on attention in respect to positive images.

Objective To investigate the influence of intensive heart rate control on inflammatory factor and cardiac function in patients with chronic heart failure. Methods From January 2015 to December 2015 ,a total of 120 CHF patients in New York Heart Association(NYHA)functional classes Ⅱ to Ⅳ were enrolled and randomized into treatment group(n=60)and control group(n=60). All the patients were in stable situation af-ter conventional drug treatment. The patients in treatment group underwent intensive heart rate control for target HR (55~60 beats/min)through adjusting the dose of metoprolol sustained-release tablets. The concentration of C-reac-tion protein(CRP),interleukin-1β(IL-1β),interleukin-6(IL-6)and tumor necrosis factorα(TNF-α)were de-tected before and after 6-month treatment. The resting heart rate and the concentration of brain natriuretic peptide (BNP),left ventricular ejection fracetion(LVEF),left ventricular end diastolic diameter(LVEDD)and left ven-tricular end systolic dimension(LVEDD)were measured at the start and 6-months after treatment. Results After 6-month treatment,the resting heart rate of the patients in the treatment group decreased significantly compared with that of the control group(P<0.001). Inflammatory factors(CRP,IL-1β,IL-6 and TNF-α)levels decreased significantly compared with that of control group (P < 0.05). The echocardiography parameters (LVEDD and LVESD)and the concentration of BNP of the patients in the treatment group decreased significantly(P < 0.05), LVEF of treatment group increased significantly(P < 0.05). Conclusion Intensive heart rate control in patients with chronic heart failure can significantly reduce Inflammatory factor levels and improve the cardiac function.

Objective This study aims to investigate the moral disgust cognitive processing of patients with obses?sive-compulsive disorder (OCD) and its relationship with OCD symptoms. Methods Twenty-eight OCD and 30 healthy controls matched for gender, age and education completed lexical decision task, recording reaction time and accuracy of words and assessing the degree of disgust. Yale-Brown obsessive-compulsive scale (Y-BOCS) and Padua Invento?ry-Washington State University Revision (PI-WUSR) were used to assess the symptoms. Results OCD group showed significantly longer reaction time to core disgust-related words [(762.69 ± 128.25) ms vs. (648.69 ± 162.66) ms] and moral disgust-related words [(798.73 ± 115.26) ms vs. (727.00 ± 106.06) ms] than the healthy controls (P<0.05). OCD group showed significantly higher aversion degree to core disgust-related words [(6.38 ± 1.78) vs. (5.03 ± 1.64)] and moral dis?gust-related words [(7.08 ± 1.23) vs. (5.77 ± 1.44)] than control group (P<0.05). Y-BOCS total score, Y-BOCS obsessive thoughts score, Y-BOCS compulsive behavior score, total score of PI-WUSR, cleaning/pollution force factor score, hurt?ing themselves and others force factor were positively correlated with two types of disgust-related words in patients group (P<0.05). Multiple stepwise regression analysis between disgust words and Y-BOCS/PI-WUSR scores pointed that only CWCF influenced disgust degree of core disgust-related words (β=0.61, P<0.01) and moral disgust-related words (β=0.54, P<0.01), respectively. Conclusion The core disgust and moral disgust of OCD are stronger compared to controls.

Objective:To investigate the correlation between polymorphisms of serine hydroxymethyltransferase1 gene and the adverse reactions of high-dose methotrexate (HD-MTX) in children with acute lymphoblastic leukemia (ALL). Methods:A total of 51 patients with ALL were treated with HD-MTX, and clinical manifestations after HD-MTX treatment were evaluated retrospectively. cD-NA was obtained from mRNA. The polymorphisms of SHMT1 gene containing rs1979277, rs3783, rs1979276, and rs12952556 sites were tested by denaturing gradient gel electrophoresis and direct sequencing. Effects of SHMT1 gene polymorphisms on HD-MTX ad-verse reactions were evaluated. Results:Severe adverse reactions in ALL patients treated with HD-MTX appeared to be mainly neutro-penia and hepatoadverse reactions. The frequency distributions of rs3783 (C>G), rs1979276 (C>T), rs12952556 (A>G), and rs1979277 (C>T) were the same. The polymorphisms of rs1979277 showed no correlation with neutropenia (P>0.05) but rs1979277 CT and TT genotypes were correlated with hepatoadverse reactions (CT: OR=0.129, 95% CI: 0.020 to 0.817, P=0.03; TT: OR=0.103, 95% CI:0.017 to 0.620, P=0.013). Conclusion: No correlation was found between the combination of rs1979277, rs3783, rs1979276, rs12952556, and neutropenia, but one or more of these loci may reduce the risk of hepatoadverse reactions.
