Objective:To investigate the current status of occupational stress among electronic manufacturing workers in Qingdao and analyze its effect on depressive symptoms and anxiety symptoms.Methods:From July to September 2022, a cluster random sampling method was employed to select frontline workers from 14 electronic manufacturing enterprises in Qingdao as the study subjects. A total of 1134 questionnaires were distributed, with 1000 valid questionnaires collected, yielding an effective response rate of 88.18%. The Core Occupational Stress Scale (COSS), the Patient Health Questionnaire-9 (PHQ-9), and the Generalized Anxiety Disorder-7 (GAD-7) were adopted to assess occupational stress, depressive symptoms, and anxiety symptoms, respectively. Binary logistic regression was employed to analyze influencing factors of occupational stress and its effects on depressive and anxiety symptoms.Results:The detection rates of occupational stress, depressive symptoms, and anxiety symptoms were 15.1% (15/1000), 7.9% (79/1000), and 13.8% (138/1000), respectively. The influencing factor analysis of occupational stress revealed that female gender ( OR=0.621, 95% CI: 0.434-0.890) and weekly working hours of 45-48 hours ( OR=0.537, 95% CI: 0.309-0.935) were protective factors ( P<0.05), while weekly working hours ≥55 hours ( OR=2.176, 95% CI: 1.290-3.670) and shift work ( OR=2.038, 95% CI: 1.412-2.940) were risk factors ( P<0.05). Spearman correlation analysis showed that the COSS score was positively related with the PHQ-9 score and the GAD-7 score ( rs=0.438, 0.289, P<0.01). Workers judged with occupational stress had 3.596 times (95% CI: 2.181-5.931, P<0.001) and 3.121 times (95% CI: 2.046-4.761, P<0.001) higher risks of detecting depressive and anxiety symptoms compared to those without occupational stress. Conclusion:Electronic manufacturing workers in Qingdao experience a certain level of occupational stress, which may increase the risk of developing depressive and anxiety symptoms. Enterprises should implement appropriate interventions to promote workers' mental health.

Objective:To analyze the prevalence and clinical characteristics of pertussis in children with different cough durations.Methods:From January 2021 to October 2022, information on children aged 0-18 years who visited eight hospitals in Shandong Province due to cough was enrolled. Pertussis serological antibody testing and/or nucleic acid testing were performed. The prevalence and clinical characteristics of pertussis were compared among the acute cough group, protracted cough group, and chronic cough group using the χ2 test or Fisher′s exact test. Results:A total of 1 565 children with cough were included in the study, of which 348 (22.24%) were laboratory-confirmed pertussis. There was a significant difference in the laboratory-confirmed rate of pertussis among different cough groups ( χ2=83.424, P<0.001). The confirmation rate of pertussis in the protracted cough group (42.21%) was significantly higher than that in the acute cough group (16.49%, P<0.05) and chronic cough group (19.50%, P<0.05). In each cough group, the age of children was significantly associated with the confirmed rate of pertussis, and the confirmed rate was relatively high in children aged 3 months to <2 years. Pertussis vaccination was significantly associated with the confirmed rate in all groups, and the confirmed rate was higher in unvaccinated children. Among laboratory-confirmed pertussis cases, the incidence of typical symptoms such as paroxysmal cough, whoop, and post-tussive emesis or sleep disturbance was significantly higher than that in the non-confirmed cases. In the protracted and chronic cough groups, the proportion of non-confirmed cases complicated with asthma/cough variant asthma (CVA) was significantly higher than that in pertussis-confirmed cases. Conclusion:There are differences in the confirmation rate of pertussis among children with different cough durations. The confirmation rate is significantly associated with age, vaccination status, and clinical symptoms. Enhancing clinical vigilance against pertussis, conducting early diagnosis, and getting timely and standardized vaccination are crucial for effectively controlling pertussis and preventing outbreaks.

Objective To assess the occupational health literacy (OHL) level and health education needs among workers in chemical enterprises in Fuling District, Chongqing City. Methods A total of 8 209 workers from 18 chemical enterprises in Fuling District, Chongqing City were selected as the research subjects using the judgment sampling method. The Occupational Health Literacy Survey Questionnaire designed by the research team was used to survey OHL levels and health education needs in workers. Results The OHL level of the research subjects was 62.1% (5 101/8 209). Multivariable logistic regression analysis showed that the OHL level of male workers was higher than that of females (P<0.01); higher OHL was also associated with higher education level, higher personal monthly income and smaller enterprises of workers (all P<0.01); production team leaders, safety production/technical management personnel, and administrative/logistics staff all had higher OHL levels than front-line operators (all P<0.05); and workers who participated in occupational health knowledge training more frequently had higher OHL levels (all P<0.05). The result of health education needs investigation showed that 97.8% of the research subjects believed that occupational health knowledge training provided by their workplaces could improve workers' OHL levels; the main channels for workers obtaining occupational health knowledge and information on workplace hazards were “employer-organized occupational health training” and “warning signs and labels”, accounting for 93.9% and 90.9%, respectively; 59.9% of workers preferred to acquire occupational health knowledge through “training or publicity organized by their workplace”. However, a current problem with occupational health knowledge publicity is its lack of diverse formats. Conclusion The OHL level of workers in chemical enterprises in Fuling District, Chongqing City is influenced by gender, educational level, enterprise size, job position, monthly personal income, and training status. The formats of occupational health knowledge publicity should be optimized.

Objective:To evaluate the analgesic efficacy of supra-inguinal fascia iliac compartment block (S-FICB)in patients with hip fracture.Methods:This study was a single-center, randomized controlled trial. Forty-eight patients who were admitted to the emergency department due to clinically diagnosed femoral neck or intertrochanteric fractures from April to September 2023 were selected. A random sequence was generated using IBM SPSS Statistics 20, and the patients were divided into 2 groups in a 1∶1 ratio( n=24 each): S-FICB group and infra-inguinal fascia iliac compartment block (I-FICB) group. Both groups received nerve blocks under ultrasound guidance, with an injection of 0.25% ropivacaine 40 ml. The primary outcome measure was sufentanil consumption within 24 h post-block. Secondary outcome measures included the distribution of local anesthetic spread as observed on CT at 0.5 h post-block, the extent of hip skin sensory reduction to pinprick, the time to first analgesic pump pressing, the number of effective analgesic pump pressing within 24 h post-block, the Numeric Rating Scale (NRS) score for pain during passive movement at 0.5 h post-block, and the static NRS scores at baseline (pre-block) and at 0.5, 3, 6, 12 and 24 h post-block. Results:Compared to I-FICB group, the consumption of sufentanil was significantly decreased, the coverage of lumbar plexus nerve branches by local anesthetics was increased, NRS scores were decreased during passive movement, the time to the first analgesic pump pressing was prolonged, the number of effective pump pressing was reduced, and static NRS scores were decreased at 24 h post-block in S-FICB group( P<0.01). In I-FICB group, no local anesthetic coverage of the iliohypogastric or ilioinguinal nerves was observed. Neither group showed coverage of the obturator nerve by the local anesthetic. Conclusions:Compared to I-FICB, S-FICB (0.25% ropivacaine 40 ml) provides a wider range of local anesthetic spread and can cover more branches of the lumbar plexus, which exerts better analgesic efficacy in patients with hip fracture. However, neither approach directly blocks the obturator nerve.

Background As a key to economic and social development, occupational groups with low levels of occupational health literacy (OHL) are considered vulnerable groups with high risks of work-related diseases and injuries. Therefore, improving the OHL of these groups is of great significance in reducing the burden on public health. Objective To master the four dimensional OHL levels and influencing factors of the key groups in Fuling District, Chongqing, and provide a basis for formulating health education programs for occupational groups in the future. Methods The Occupational Health Literacy Questionnaire of Key Populations was distributed online to investigate the key occupational groups in Fuling District through stratified cluster sampling. The survey collected data on basic demographic information, legal knowledge of occupational health, basic knowledge of occupational health protection, basic skills of occupational health protection, and healthy working style and behavior. Univariate analysis, logistic regression, and nomogram were used to analyze the above data. Results This survey distributed 4824 questionnaires, of which 4677 were valid, with a recovery rate of 97.0%. The dimensional OHL levels of key occupational groups in Fuling District from high to low were: healthy working style and behavior (79.1%), basic knowledge of occupational health protection (78.4%), legal knowledge of occupational health protection (43.3%), and basic skills of occupational health protection (37.6%). The results of logistic regression showed that the occupational health legal knowledge levels in the groups of high school/vocational high school/technical secondary school and above (reference: primary school and below) (OR=1.47, 95%CI: 1.05, 2.05), ≥3000 yuan of monthly income (reference: <3000 yuan of monthly income) (OR=1.39, 95%CI: 1.06, 1.84), and medium enterprises (reference: micro enterprises) (OR=1.84, 95%CI: 1.29, 2.63) were higher; the occupational health legal knowledge level in the electricity, heat, gas, and water production and supply industry was lower than that in the mining industry (OR=0.68, 95%CI: 0.47, 0.97); the basic knowledge levels of occupational health protection in the groups of ≥ 3 years of service (reference: < 3 years of service) (OR=0.78, 95%CI: 0.65, 0.94) and medium enterprises (reference: large enterprises) (OR=0.78, 95%CI: 0.64, 0.95) were lower; the basic knowledge level of occupational health protection in the ethnic minorities was higher than that in the Han ethnic group (OR=1.73, 95%CI: 1.04, 2.87); the occupational health protection basic skill level in the group of ≥ 3 years of service (reference: < 3 years of service) (OR=0.69, 95%CI: 0.60, 0.79) was higher; the level of healthy working style and behavior in the group of ≥ 11 years of service (reference: < 3 years of service) (OR=0.73, 95%CI: 0.59, 0.89) was lower; the level of healthy working style and behavior in the group of high school/vocational high school/technical secondary school and above (reference: primary school and below) (OR=1.60, 95%CI: 1.15, 2.23) was higher. The nomogram showed that educational level and monthly income had the greatest impact on the occupational health legal knowledge level; length of service had the greatest impact on the basic knowledge of occupational health protection level and the healthy working style and behavior level. Conclusion In the future, the focus of health education and health promotion in Fuling District should be implemented to improve the basic skills of occupational health protection and the legal knowledge of occupational health, especially for workers with low education, low income, from micro enterprises, and on the job, so as to improve their skills of occupational health protection and legal knowledge, and to control the occurrence of occupational or work-related diseases.

Objective To compare the value of Child-Pugh score, Model for End-Stage Liver Disease (MELD) score, MELD combined with serum sodium concentration (MELD-Na) score, CLIF Consortium Acute Decompensation (CLIF-C AD) score, and Freiburg index of post-transjugular intrahepatic portosystemic shunt (TIPS) survival (FIPS) score in predicting the survival of patients undergoing TIPS. Methods A retrospective analysis was performed for the clinical data of 447 patients with liver cirrhosis who underwent TIPS in several hospitals in southwest China, among whom there were 306 patients in the survival group and 62 in the death group. The scores of the above five models were calculated, and a survival analysis was performed based on these models. The independent samples t -test was used for comparison of normally distributed continuous data between groups, and the non-parametric Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups; the Pearson chi-square test was used for comparison of categorical data between groups; a multivariate Cox regression analysis was used for correction analysis of known influencing factors with statistical significance which were not included in the scoring models; the Kaplan-Meier method was used to evaluate the discriminatory ability of each model in identifying risks in the surgical population, and the log-rank test was used for analysis. The area under the receiver operating characteristic curve (AUC), C-index at different time points, and calibration curve were used to evaluate the predictive ability of each scoring model. Results Compared with the death group, the survival group had significantly lower age ( Z =2.884, P < 0.05), higher albumin ( t =3.577, P < 0.05), and Na + ( Z =-3.756, P < 0.05) and significantly lower proportion of patients with alcoholic cirrhosis ( χ 2 =22.674, P < 0.05), aspartate aminotransferase ( Z =2.141, P < 0.05), prothrombin time ( Z =2.486, P < 0.05), international normalized ratio ( Z =2.429, P < 0.05), total bilirubin ( Z =3.754, P < 0.05), severity of ascites ( χ 2 =14.186, P < 0.05), and scores of the five models (all P < 0.05). Survival analysis showed that all scoring models effectively stratified the prognostic risk of the patients undergoing TIPS. Comparison of the C-index of each scoring model at different time points showed that Child-Pugh score had the strongest ability in predicting postoperative survival, followed by MELD-Na score, MELD score, and CLIF-C AD score, and FIPS score had a relatively poor predictive ability; in addition, the prediction efficiency of each score gradually decreased over time. Child-Pugh score had the largest AUC of 0.832 in predicting 1-year survival rate after surgery, and MELD-Na score had the largest AUC of 0.726 in predicting 3-year survival rate after surgery, but FIPS score had a poor ability in predicting 1- and 3-year survival rates. Conclusion All five scoring models can predict the survival of patients with liver cirrhosis after TIPS and can provide effective stratification of prognostic risk for such patients. Child-Pugh score has a better ability in predicting short-term survival, while MELD-Na score has a better ability in predicting long-term survival, but FIPS score has a relatively poor predictive ability in predicting both short-term and long-term survival.

Objective:To study the relationship between fasting glucose (FPG) and gene polymorphisms of adiponectin (ADIPOQ), interleukin 6 (IL-6) and tumor necrosis factor-alpha (TNF-α) in early pregnancy and insulin resistance in patients with gestational diabetes mellitus (GDM).Methods:Sixty patients diagnosed with GDM within 24 -28 weeks from January 2022 to August 2022 in the Affiliated Hospital of Jining Medical University were selected as the GDM group, and another 60 healthy pregnant women were taken as the normal control group. The fasting insulin (FINS), FPG levels and the homeostatic model assessment insulin resistance index (HOMA-IR) and other clinical data were detected at 8 -12 weeks of pregnancy. Meanwhile, polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to detect the polymorphisms of ADIPOQ gene at S0100622 locus, IL-6 gene at S01006318 locus, TNF- α gene at S01009718. Receiver operating characteristics(ROC) curve was used to evaluate the diagnostic performance of FPG combined with polymorphisms of ADIPOQ, IL6 and TNF-α in predicting GDM in early pregnancy.Results:The body mass index (BMI), early pregnancy FPG, mid pregnancy FPG, 75 g oral glucose tolerance test (OGTT) 1 h blood glucose, OGTT 2 h blood glucose, glycosylated hemoglobin (HbA 1c), FINS and HOMA-IR in the GDM group were higher than those in the normal control group: (27.1 ± 2.6) kg/m 2 vs. (25.6 ± 2.5) kg/m 2, (4.7 ± 1.3) mmol/L vs. (4.1 ± 1.5) mmol/L, (5.5 ± 1.3) mmol/L vs. (4.2 ± 1.2) mmol/L, (6.3 ± 1.5) mmol/L vs. (5.5 ± 1.7) mmol/L, (6.0 ± 1.5) mmol/L vs. (5.2 ± 1.4) mmol/L, (5.8 ± 0.7)% vs. (5.2 ± 0.6)%, (6.4 ± 1.1) mU/L vs. (5.2 ± 1.2) mU/L, 1.5 ± 0.6 vs. 1.0 ± 0.7, there were statistical differences ( P<0.05). According to the risk assessment of genotype, the high-risk rate in the GDM group was 88.33% (53/60), while the normal control group was 56.67% (34/60), there was statistical difference ( χ2 = 17.67, P<0.05). In GDM group, the HOMA-IR with ADIPOQ gene S0100622 locus TG genotype was higher than that with TT genotype: 6.58 ± 0.89 vs. 4.98 ± 0.58; the HOMA-IR with IL-6 gene S01006318 locus CG genotype was higher than CC and GG genotype: 8.13 ± 1.31 vs. 6.53 ± 0.81, 4.85 ± 0.54, the HOMA-IR with TNF-αgene S01009718 locus AG genotype was higher than GG genotype: 6.31 ± 1.04 vs. 5.16 ± 0.82, there were statistical differences ( P<0.05). Logistic regression analysis showed that age>35 years, previous diabetes history, BMI, TG genotype at S0100622 locus of ADIPOQ gene, CG genotype at S01006318 locus of IL-6 gene, AG genotype at S01009718 locus TNF- α gene were risk factors for the onset of GDM ( P<0.05). The results of ROC curve analysis showed that the area under the curve (AUC) of FPG for predicting GDM onset was 0.737, with a specificity of 83.50%; FPG combined with ADIPOQ, IL-6, TNF- α genetic risk assessment predicted with AUC of 0.921 and a specificity of 86.80%. Conclusions:ADIPOQ gene TG genotype at S0100622 locus, IL-6 gene CG genotype at S01006318 locus, TNF- α gene AG genotype at the S01009718 locus has a certain correlation with the onset of GDM, which can predict the onset of GDM and is associated with perioperative insulin resistance in patients. Early FPG testing combined with genetic screening has practical clinical guiding significance in reducing adverse pregnancy outcomes for mothers and infants.
