ABSTRACT
Background Work-related musculoskeletal disorders (WMSDs) are one of the major occupational health problems in the world. Pharmaceutical industry is an important part of China's national economy. At present, there are few related studies reported at home and abroad. Objective To investigate the status and influencing factors of WMSDs in chemical pharmaceutical industry. Methods A cross-sectional epidemiological survey was conducted among all workers from three chemical pharmaceutical enterprises in Guangzhou. The Musculoskeletal Disorders Questionnaire was used to collect information on demographic characteristics, symptoms of musculoskeletal disorders, types of work, work organization, and and work postures. Multiple logistic regression method was used to analyze the risk factors of WMSDs in chemical pharmaceutical workers. Results In this study, 563 workers were selected as subjects. The total prevalence rate of WMSDs symptoms in the chemical pharmaceutical workers was 43.9% (247/563), and the leading body part-specific prevalence rate from high to low was 34.3% in the lower back, 24.3% in the upper back, 24.0% in the shoulders, and 23.8% in the neck. The prevalence rate of WMSDs symptoms in multiple body parts (30.0%) was 2.16 times higher than that in single body part (13.9%), and the prevalence rate of WMSDs symptoms in four body parts was the highest (11.4%). The results of multiple logistic regression analysis showed that age ≥50 years (reference age <30 years) (OR=2.140, 95%CI: 1.054-4.345), often or very often (reference never/rarely) long-time head rotating (OR=2.695, 95%CI: 1.753-4.142) and long-time keeping arms above shoulders (OR=1.902, 95%CI: 1.108-3.265) increased the risk of reporting WMSDs symptoms (P<0.05). Regarding education level, workers with high school and technical secondary school (OR=0.333, 95%CI: 0.175-0.636) or college and above (OR=0.413, 95%CI: 0.216-0.790) education had a lower risk of reporting WMSDs symptoms than those with middle school or below (P<0.05). Conclusion The prevalence rate of reporting WMSDs symptoms in chemical pharmaceutical industry is high, the involving body parts are lower back, upper back, shoulders, and neck, and reporting simultaneous occurrence of WMSDs symptoms in multiple body parts is common. The chemical pharmaceutical manufacturers can reduce the risk of WMSDs by strengthening the training on workers' ergonomics knowledge, paying attention to the less educated personnel, protecting the elderly workers, and avoiding awkward work postures, like rotating head for a long time and raising arms over shoulders.
ABSTRACT
Objective:This study was performed to assess the effect of glycemic control on atrial fibrillation recurrence rates after heart surgery concomitant with Cox-Maze Ⅳ ablation.Methods:A retrospective analysis was performed on 317 diabetic patients with atrial fibrillation who underwent cardiac surgery combined with Cox-Maze Ⅳ ablation in our hospital from May 2016 to February 2020. The patients were followed up for(37.7±27.7) months, and the data of atrial fibrillation recurrence and clinical outcome were collected and compared. The limited cubic spline model was used to analyze the dose-relationship between HbA1c level and the recurrence of atrial fibrillation. The univariate and multivariate Cox proportional regression analysis was used to explore the risk factors of recurrent atrial fibrillation after Cox-Maze Ⅳ ablation. Results:Higher glycated hemoglobin(HbA1c) at the time of ablation was associated with higher post-ablation recurrence rates. The cumulative survival freedom from atrial fibrillation recurrence for patients with HbA1c ≥7.4% at time of operation at 12, 24, 36 and 48 months were 96.3%、75.8%、52.7% and 35.7%, respectively( P<0.001). Besides, the rates of all-cause mortality, cardiac mortality and rehospitalization were significantly lower in patients with HbA1c<7.4%(1.7% vs. 6.3%, P=0.03; 1.1% vs. 5.6%, P=0.02 and 5.7% vs. 20.4%, P=0.01). The multivariate Cox regression model showed that HbA1c was an independent risk factor for atrial fibrillation recurrence( P<0.05). Conclusion:Higher preoperative HbA1c levels were associated with increased recurrence of atrial fibrillation and adverse clinical outcomes in patients undergoing cardiac surgery combined with Cox-Maze Ⅳ ablation.
ABSTRACT
Background The operation mode of automobile manufacturing industry (AMI) makes workers have different degrees of occupational stress and burnout, which may lead to negative emotions and depressive symptoms. Objective To study the relationship between occupational stress, job burnout, and depressive symptoms in AMI workers. Methods In this study, 1300 workers from a Guangzhou AMI company were selected as subjects by cluster random sampling method. Occupational stress, job burnout, and depressive symptoms of the workers were assessed by using the Effort-Reward Imbalance (ERI) questionnaire, the Maslach Burnout Inventory general survey questionnaire, and the Patient Health Questionnaire-9, respectively. Hierarchical regression was used to analyze the effects of occupational stress and job burnout on depressive symptoms in AMI workers. Mediating effect model was used to analyze the mediating effect of job burnout on the relationship between occupational stress and depressive symptoms. Results There were 1300 questionnaires distributed, 1228 valid questionnaires collected, with a 94.5% recovery rate. The ERI ratio of 1228 AMI workers was 1.06±0.72, and the positive rate of occupational stress was 37.3% (458/1228). The score of job burnout was 2.18±1.37, and the positive rate of job burnout was 62.6% (769/1228). The score of depressive symptoms was 10.27±6.42, and the positive rate of depressive symptoms was 47.1% (578/1228). The dimensional scores of effort and over-commitment in occupational stress as well as emotional exhaustion and depersonalization in job burnout of AMI workers were positively correlated with the depressive symptom scores (rs=0.415, 0.571, 0.573, 0.593, P＜0.05). The dimensional scores of reward and personal achievement were negatively correlated (rs=−0.454, −0.339, P＜0.05). The percentages of variance in depressive symptoms score explained by occupational stress and job burnout were 26.7% and 16.6%, respectively. Job burnout had a partial mediating effect between the three dimensions of occupational stress and depressive symptoms, and the mediating effect values were −0.2832 (95%CI: −0.3250– −0.2434), 0.3553 (95%CI: 0.3071–0.4041), and 0.4193 (95%CI: 0.3681–0.4725), respectively. Conclusion AMI workers' occupational stress affects job burnout, but also indirectly affects depressive symptoms. Job burnout partially mediates the association between occupational stress and depressive symptoms. Reducing occupational stress and burnout levels of AMI workers may alleviate depressive symptoms.

According to the current situation of online drugstores in China ， combined with the development mode and operation strategy in foreign countries ，it is suggested to improve relevant laws and regulations，and strengthen legal support ；strengthen the government supervision to ensure drug safety ；use the industrial power to standardize medicine operation behavior ；set up the third part trading platform to promote medical insurance payment.
ABSTRACT
Hypertension is the largest risk factor for cardiovascular disease, the leading cause of mortality worldwide. As blood pressure regulation is influenced by multiple physiological systems, hypertension cannot be attributed to a single identifiable etiology. Three decades of research into Mendelian forms of hypertension implicated alterations in the renal tubular sodium handling, particularly the distal convoluted tubule (DCT)-native, thiazide-sensitive Na-Cl cotransporter (NCC). Altered functions of the NCC have shown to have profound effects on blood pressure regulation as illustrated by the over activation and inactivation of the NCC in Gordon's and Gitelman syndromes respectively. Substantial progress has uncovered multiple factors that affect the expression and activity of the NCC. In particular, NCC activity is controlled by phosphorylation/dephosphorylation, and NCC expression is facilitated by glycosylation and negatively regulated by ubiquitination. Studies have even found parvalbumin to be an unexpected regulator of the NCC. In recent years, there have been considerable advances in our understanding of NCC control mechanisms, particularly
ABSTRACT
After traumatic brain injury(TBI), as an immune signal complex in cytoplasm, the assembly and activation of inflammasomes can induce pyroptosis, trigger extensive inflammations, aggravate brain tissue damage, lead to delayed cell death and progressive neurodegeneration, and cause neurological dysfunction, which plays a key role in the development and prognosis of the disease. After TBI, the mechanism of pyroptosis mediated by inflammasomes and its targeted treatments have become the focus of recent researches. The authors review the research progress in inflammasomes-mediated pyroptosis in terms of related signal pathways, their activation and regulation and application of targeted drugs after TBI, so as to provide references for clinical treatments.
ABSTRACT
The myelin-associated protein Nogo-A was considered to be the axon growth inhibitory factor, which participates in a variety of pathophysiological regulation of nervous system. In recent years, a growing number of studies have shown that Nogo-A protein is closely related to epilepsy by regulating dendritic plasticity, mediating abnormal nerve migration and regulating glial cell activation, etc. This article will review the research progress of Nogo-A in epilepsy in recent years.
ABSTRACT
OBJECTIVE@#To study the effect of dexmedetomidine (Dex) on cognitive dysfunction induced by tibial fracture in rats.@*METHODS@#Sixteen male SD rats were randomized into control group and tibial fracture group, and the behavior indicators were measured on days 1, 3, 5 and 7 after tibial fracture and the expressions of CX3L1 protein and mRNA in the hippocampus were detected. Another 24 male SD rats were randomly divided into control group, tibial fracture group, and tibia fracture with CX3CL1 antibody group, and the behavior indicators and hippocampal CX3L1 protein expression were evaluated after corresponding treatments. In another experiment, we randomized 24 male SD rats into control group, tibial fracture group and tibial fracture with Dex treatment, and tested their hippocampal CX3L1 protein and mRNA expressions as well as the behavior indicators after the treatments.@*RESULTS@#Compared with the control rats, the rats with tibial fracture spent significantly less time in the novel arm on days 1, 3, 5 and 7 after the fracture ( < 0.05) with obviously lowered expressions of CX3L1 protein and mRNA in the hippocampus ( < 0.05). In the rats with tibial fracture, treatment with CX3CL1 antibody further decreased the time spent in the novel arm ( < 0.05) and the expression level of CX3L1 protein in the hippocampus ( < 0.05); In contrast, treatment with Dex significantly increased the time spent time in the novel arm ( < 0.05) and enhanced the hippocampal expressions of CX3L1 protein and mRNA in rats with tibial fractures ( < 0.05).@*CONCLUSIONS@#Dex can alleviate cognitive dysfunction induced by tibial fracture in rats by increasing the expression of CX3CL1 in the hippocampus.

Objective To discuss the clinical diagnosis and treatment of xanthogranulomatous pyelonephritis (XGP).Methods Clinical data of 41 XGP patients admitted from May 1981 to December 2017 were retrospectively analyzed.There were 17 male cases and 24 female cases,aged from 23 to 78 years,with an average age of 57 years.All were unilateral lesions,including 19 cases on the left and 22 cases on the right.Disease duration ranged from 1 week to 12 years,with an average of 3.5 years.The clinical manifestations showed that 7 cases with gross hematuria (17.1％),16 cases with palpable flank or abdominal mass (39.0％),36 cases with flank pain (87.8％),26 cases with acute or intermittent fever (63.4％) and 17 cases with weight loss (41.5％).Laboratory findings showed that 28 cases with leukocytosis (68.3％),24 cases with anemia (58.5％),27 cases with pyuria (65.9％),positive urine culture 19/34 (55.9％),positive urine lipid-laden macrophages 3/14(21.4％),and 20 cases with rapid erythrocyte sedimentation rate (48.8％).Imaging examination:among 35 patients who received CT examination,25 were diagnosed as XGP,mainly presenting diffuse changes in the kidney with enlarged renal shadow,accompanied by diffusive distribution of multiple low-density lesions.There was no obvious enhancement in the low-density lesions on enhanced scan,accompanied by thickening of renal fascia,adhesion to psoas major muscle or involvement of surrounding tissues and organs.According to the imaging results,there were 33 cases of diffuse type and 8 cases of localized type in this group.Renal biopsy was performed 11 cases and 3 cases were diagnosed as XGP.Results All patients were treated with surgical procedure.33 patients with diffuse type were performed nephrectomy.6 of the 8 patients with localized type underwent partial nephrectomy successfully,and the other 2 patients underwent nephrectomy due to severe renal adhesion and unclear lesion boundaries.All postoperative pathologies suggested xanthogranulomatous pyelonephritis.Patients were followed up for 9 months to 10 years postoperatively,with an average of 4.5 years.All patients had no recurrence.Conclusions The clinical manifestations of XGP are lack of specificity.Diagnosis is difficult and depends on pathology.According to imaging examination,lesions can be divided into diffuse type and localized type.Nephrectomy and partial nephrectomy were performed respectively.
ABSTRACT
OBJECTIVE: To explore the effect of wearing earphone to listen to music on the high-frequency noise-induced hearing loss(NIHL) in noise-exposure workers. METHODS: A total of 651 male noise-exposure workers in an automobile manufacturer were selected as study subjects by using judgment sampling method. The level of noise exposure in the individuals and the pure tone hearing threshold were tested. According to the frequency of wearing earphone to listen to music after work, the subjects were divided into low-, medium-and high-frequency earphone-using groups, with 60, 436 and 155 workers in each group, respectively. The effects of wearing earphone to listen to music combined with occupational noise exposure on high-frequency NIHL were analyzed. RESULTS: The high-frequency NIHL detection rate of the study subjects was 31.3%(204/651). The detection rate of high-frequency NIHL in these three groups from low to high was low-, medium-and high-frequency earphone-using groups(P<0.01). The detection rate of high-frequency NIHL in the high-frequency earphone-using group was higher than that of the low-and medium-frequency earphone-using groups(43.2% vs 25.0%, 43.2% vs 28.0%, P<0.01). Multivariate logistic regression analysis showed that wearing earphones to listen to music was a risk factor for high-frequency NIHL in noise-exposure workers(P<0.01) after eliminating the influence of confounding factors such as age, length and level of noise-exposure, and wearing anti-noise ear plugs. The higher frequency of wearing earphone to listen to music, the higher risk of high-frequency NIHL. CONCLUSION: Wearing earphone to listen to music after work and occupational noise exposure had a synergistic effect on high-frequency NIHL in noise-exposure workers.
ABSTRACT
OBJECTIVE: To observe the status of protein kinase B(Akt) signaling pathway in Akt phosphorylation induced by free silica(SiO_2) in mouse monocyte macrophage cell RAW264.7, and the role of Akt signaling pathway in early inflammatory response of silicosis. METHODS: i) RAW264.7 cells were routinely cultured and divided into SiO_2 stimulation groups at 5 different time points, and were stimulated for 15, 30, 60, 120 and 240 minutes with SiO_2 suspension with a final concentration of 100 mg/L, and a control group without SiO_2 treatment. At the end of treatment, the cells were collected and the expression of phospho-(Ser/Thr) Akt(p-Akt) was detected by Western blotting to select the optimal time of treatment. ii) RAW264.7 cells were divided into control group(no treatment), SiO_2 exposure group(previous concentration of 100 mg/L SiO_2 suspension) and intervention group(pre-treated with Akt activation inhibitor deguelin for one hour and then treated with 100 mg/L SiO_2 suspension), samples were collected after incubation for 60 minutes. The p-Akt expression and distribution in cells were detected by cellular immunofluorescence assay, the relative expression of p-Akt in cells was detected by Western blotting, and the levels of tumor necrosis factor-α(TNF-α) and transforming growth factor-β1(TGF-β1) in the supernatant of cells were detected by enzyme-linked immunosorbent assay. RESULTS: i) The optimal treatment time of RAW264.7 cells for SiO_2 exposure model was 60 minutes in vitro. ii) The results of cellular immunofluorescence assay showed that Akt phosphorylation was activated in RAW264.7 cells after stimulant with SiO_2, and the fluorescence of p-Akt was enhanced in the SiO_2 exposure group than the control group, and in the intervention group it was relatively weaker than the SiO_2 exposure group. The relative expression of p-Akt as well as the levels of TNF-α and TGF-β1 in the SiO_2 exposure group and the intervention group were higher than that in the control group(P<0.05), and the above three idexes in the intervention group were lower than the SiO_2 exposure group(P<0.05). CONCLUSION: Akt signaling pathway is involved in the process of SiO_2-induced macrophages phosphorylation, and participates in the early inflammatory response of silicosis.

The multivariate logistic regression analysis showed that the prevalence risk of hypertension increased with the increase of CNE after adjusting for confounding factors such as body mass index,smoking and wearing personal protective equipment in automobile manufacturing workers( P < 0. 01). CONCLUSION: There is a dose-effect relationship between prevalence of hypertension and CNE in automobile manufacturing workers who exposed to noise.
ABSTRACT
Objective To investigate the local or systemic effects of initial periodontal therapy on peritoneal dialysis in patients with chronic kidney disease and periodontitis. Methods Sixty-one patients with both periodontitis and regular peritoneal dialysis were selected in this study and were randomly divided into observation group (n=31) and control group (n=30). Patients in observation group were given periodontal initial therapy (ultrasonic supragingival scaling and ultrasonic subgingival irrigation, drug, root planing, oral health education) and peritoneal dialysis treatment. Patients in control group were given only peritoneal dialysis treatment. Clinical parameters including plaque index (PLI), gingival index (GI) and probing depth (PD) were detected before and one month after treatment in two groups. The concentrations of high-sensitivity C-reactive protein (hs-CRP) in gingival sulcus fluid and serum samples were measured by immune transmission turbidity method in two groups. Results There were no significant differences in PLI, GI, PD, hs-CRP of gingival sulcus fluid, and serum hs-CRP before treatment between the two groups. After one-month initial therapy, all the indexes were decreased in observation group, which were significantly different compared with those before treatment (P<0.05). And all the indexes were significantly lower in observation group than those of control group. There were no significant differences in PLI, PD, GI, hs-CRP of gingival sulcus fluid, and serum hs-CRP between control group and observation group before treatment. Conclusion Periodontal initial treatment can improve the periodontal inflammation in patients with chronic kidney disease, and reduce the concentration of systemic inflammatory factor hs-CRP, decreasing the risk of infection.
ABSTRACT
OBJECTIVE: To explore the relationship between noise-induced hearing loss, hypertension and abnormal electrocardiogram(ECG) in noise-exposed workers. METHODS: A judgment sampling method was adopted to select 555 male workers with hearing loss as study group and 555 male workers with normal hearing as control group in the similar environment in an automobile manufacturing enterprise in Guangzhou. Pure tone audiometry,blood pressure measurement and ECG examination were performed in both groups to analyze the relationship between hearing loss and hypertension and abnormal ECG. RESULTS: The prevalence rate of hypertension and abnormal ECG was higher in the hearing loss group than the control group(P < 0. 05). The multiple logistic regression analysis showed that after adjusting confounding factors such as age,seniority,body mass index,drinking et al,the risk of hypertension in hearing loss group was higher than the control group(P < 0. 05) and the odds ratio(OR) was 2. 255 [95% confidence interval(CI) : 1. 093-4. 655 ],while adjusting the confounding factor of drinking,the risk of ECG abnormalities in hearing loss group was higher than the control group(P < 0. 05) and the OR was 1. 408(95% CI: 1. 027-1. 930). CONCLUSION: Workers exposed to noise with hearing loss increase the risk of hypertension and abnormal ECG.
