Abstract
Objective: To analyze the status and its influencing factors of job burnout among female workers of labor-intensive enterprises. Methods: A total of 750 female workers from 5 labor-intensive enterprises in Guangdong Province were selected as the study subjects by random cluster sampling method in August, 2019. 665 valid questionnaires were collected, and the effective recovery rate was 88.67%. The Maslach Burnout Inventory-General Survey was used to assess job burnout and its influencing factors were analyzed. Results: Among 665 female workers, 429 (64.51%) found to have different levels of burnout, among which 380 (57.14%) were mild to moderate burnout and 49 (7.37%) were severe burnout. The comprehensive scores of job burnout in different age, marital status, current post working age, working time per week, personal monthly income, working system and occupational stress groups were statistically significant (P<0.01) . There were significant differences in the score of emotional exhaustion in different age, marital status, current working age, working time per week, personal monthly income and occupational stress groups (P<0.05) . There were significant differences in the dimensions of depersonalization in different age, weekly work time, personal monthly income, working system and occupational stress groups (P<0.05) . There were significant differences in the dimensions of low individual achievement in different education levels, weekly work time, working system and occupational stress groups (P<0.05) . Conclusion: The female workers of labor-intensive enterprises are generally have mild to moderate job burnout. The main influencing factors of job burnout are weekly work time and occupational stress.

Abstract
OBJECTIVE To evaluate the role of polysaccharide from Phellinus igniarius (PPI) in the improvement of oxidative stress, hepatic granuloma and hepatic fibrosis in Schistosoma japonicum-iniected in mice. METHODS The mouse model of schistosomiasis was established by S. japonicum cercariae infection via the abdomen. Balb/c mice were randomly assigned into 5 groups, including the healthy control group (Group A), infection control group (Group B), PPI treatment group (Group C), praziquantel treatment group (Group D) and PPI-praziquantel combination group (Group E), of 10 mice in each group. Each mouse in groups B, C, D and E was infected with (30 ± 2) S. japonicum cercariae. Then, mice in groups D and E were given praziquantel by gavage at a dose of 500 mg/kg for successive two days on day 42 post-infection, while mice in groups C and E were given PPI by gavage at a dose of 400 mg/kg for successive 30 days on day 42 post-infection. Histopathological changes of hepatic tissues were observed using hematoxylin-eosin (HE) staining, and serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), hyaluronic acid (HA), laminin (LN) were determined, while the activities of malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-PX), glutathione reductase (GSH-R) and glutathione (GSH) were detected in Mouse liver homogenates. The expression of transforming growth factor-beta (TGF-β) and alpha-smooth muscle actin (α-SMA) was quantified in hepatic tissues using immunohistochemistry, and the Nrf2 and Gsta4 gene expression was quantified using quantitative real-time PCR (qPCR) assay. RESULTS Untreated mice presented typical pathological changes of schistosomal hepatic disorders, while PPI treatment effectively alleviated hepatic egg granulomas and collagen deposition. S. japonicum infection resulted in aggravation of hepatic lipid peroxidation, induction of oxidative stress, elevated serum MDA level and a reduction in the activity of GSH and antioxidant enzymes activities in mice. As compared to infected but untreated mice, PPI treatment suppressed hepatic lipid peroxidation, increased the GSH activity and restored the activity of antioxidant enzymes. In addition, PPI treatment inhibited the TGF-β signaling pathway and up-regulated the Nrf2 and Gsta4 gene expression. CONCLUSIONS PPI plays a critical role in the treatment of schistosomiasis-induced hepatic fibrosis. It may improve oxidative stress damages through up-regulating Nrf2 and Gsta4 gene expression, thereby suppressing the development of hepatic egg granulomas and hepatic fibrosis.

Abstract
OBJECTIVE For patients who had hemipelvectomies involving the resection of a portion or the whole of the pubis, bony reconstruction was not recommended commonly. However, the soft tissue reconstruction of the lower abdominal wall may benefit these patients. The object of the study was to determine the clinical effect of lower abdominal wall reconstruction with LARS ligament after pubic tumor resection interms of patient-reported and objective outcome. METHODS In this series, we reviewed twenty-five patients who underwent pubic tumor resection followed by reconstruction with LARS ligament between February 2012 and February 2018 retrospectively. We evaluated the clinical outcome and complication of this surgical treatment. The function outcome was evaluated according the musculoskeletal tumor society scores (MSTS) for all the patients at the end of the last follow-up. RESULTS All the patients were stable during the surgery. There were eight patients who underwent resection of superior ramus of pubis, five patients who had resection of inferior ramus of pubis, and twelve patients who received both superior and inferior ramus of pubis. For all the patients, the mean blood loss was (774±580) mL. The mean operation time was (138±25) min. The mean hospital stay was (19±6) d. For the patients who had resection of superior ramus, inferior ramus, as well as both superior and inferior ramus, the mean blood loss were (763±802) mL, (730±315) mL and (808±485) mL, respectively. The mean operation time were (133±27) min, (135±35) min and (143±20) min, respectively. The mean hospital stay were (18±5) d, (22±9) d and (19±6) d, respectively. The mean follow-up time was (37±21) months. Local recurrence was observed in one patient with chondrosarcoma. One patient with renal cancer metastasis died of the disease. No ligament infection, ligament related complication and incisional hernias were observed. Twenty-three patients could ambulate without assistive devices, and the remaining two could walk by crutches. Postoperative pain was reported as none in nineteen patients, mild in three, and moderate in three. From a functional point, the mean MSTS score was 87±4. CONCLUSION Lower abdominal wall reconstruction with LARS ligament after pubic tumor resection could have satisfactory clinical outcome. It could prevent the occurrence of herniation, decrease the infection rate by minishing the dead space, and achieve good patient-reported outcome.

Abstract
Objective: This study was aimed to analyze the epidemic trend and predict the incidence trend of occupational diseases during 2006-2015 in Guangdong province, which may provide the theoretical foundation for occupational disease risk assessment and precise control and prevention. Methods: We analyzed the number of reported occupational disease cases, the constituent ratio, the average age and working-age of patients. We also performed the linear-by-linear association test of new incidence, median age and median working-age by curve-fitting method, of which the diagnostic year was set as the independent variable. Meanwhile, we designed an ARIMA model to predict the variation tendency of occupational diseases in 2017-2020. Results: (1) During 2006-2015, the total reported cases of occupational disease is 5289, including 2101 cases of occupational pneumoconiosis (39.7%) , 1363 cases of occupational poisoning (25.8%) , and 864 cases of occupational otolaryngological and stomatological disease (16.3%) . (2) The number of occupational diseases and pneumoconiosis have a straight upward trend (R(2)=0.851, R(2)=0.856) , while the number of occupational otolaryngological and stomatological disease and occupational tumor have a exponential trend (R(2)=0.914, R(2)=0.696) . The constituent ratio of occupational poisoning is decreasing, and the constituent ratio of occupational otolaryngological and stomatological disease is increasing. (3) The average onset age is 40 (33, 46) years old, and the average onset working-age is 6 (3, 11) years. Both of them have a straight upward trend (R(2)=0.954、R(2)=0.792) . The onset age of pneumoconiosis, occupational poisoning and occupational otolaryngological and stomatological disease have a upward trend. In addition, the onset working-age of occupational poisoning and pneumoconiosis have a upward trend. (4) The number of occupational diseases in 2017-2020 is predicted to be between 902-1231. Conclusion: Occupational diseases in Guangdong province showed a trend of high incidence. The age and working-age of occupational diseases showed an extended trend. Therefore, our work of occupational epidemic trend may provide some bases for the occupational disease risk assessment and precise control and prevention.

Abstract
OBJECTIVES To explore the causes and risk factors of inpatient death for patients with warfare-related limb trauma. METHODS A retrospective study involving 339 patients with warfare-related limb trauma who were admitted to our hospital from 1998 to 2002 was conducted. Autopsy was performed for 15 cases who died in order to investigate the cause of death. Furthermore, based on the clinical features of warfare-related trauma patients, 11 factors were selected for further analysis: X1: causes of trauma, X2: shock after injury, X3: time from injury to hospital admission, X4: injured sites, X5: combined trauma (including head, thorax, abdomen, and vascular injury), X6: number of surgical procedures, X7: foreign body remaining, X8: fracture, X9: amputation, X10: duration of tourniquet homeostasis, X11: infection. All variables were available in all cases, and all parameters were quantified and fed into a computer. Multivariate statistical analysis was performed with a logistic regression model to elucidate the risk factors influencing death. RESULTS Fifteen of the 339 inpatient cases died (4.4%). The causes were primarily acute renal failure (ARF) (seven cases, 46.7%), pulmonary embolism (PE) (three cases, 20.0%), multiple organ system failure (MOSF) (two cases, 13.3%), and gas gangrene (three cases, 20.0%). There was one case of gas gangrene with concomitant ARF, and one of gas gangrene with MOSF. The primary risk factors influencing death included shock, amputation, and complicating infection (P < 0.05). CONCLUSION The primary cause of death from warfare-related limb trauma is ARF. The appropriate and prompt management of shock patients, the correct timing of amputation, and the prevention and correct handling of infection are important in reducing mortality.

Abstract
To decipher the molecular mechanism of EGCG induced HL-60 cell apoptosis, alterations of gene expression spectra in HL-60 cell line cells after treatment with EGCG were screened by cDNA chip, and analyzed with the GenePix 3.0 twice; and the cDNA chip results further identified by RT-PCR. Ninety-seven genes among the total 8398 (1.15%) showed consistent significant differential expression in the duplicated cDNA chip assessments. Thirty-nine genes (40.2%) were up-regulated and 58 genes (59.8%) were down-regulated; and the randomly selected four performed RT-PCR results agreed with the cDNA chip data. The results suggest that the apoptosis of HL-60 cells induced by EGCG is a progressive transformation process regulated by a variety of genes.
