Abstract
BACKGROUND Periodontitis is a complex chronic inflammatory disease that is particularly associated with health-related conditions such as smoking, excessive drinking and depression. This research aimed to investigate the interaction between these lifestyles factors on periodontitis risk. METHODS This study included participants who participated in the National Health and Nutrition Examination Survey in the United States between 2009 and 2014. They had completed oral health-periodontal examination, Smoking-Cigarette Use Questionnaire, Alcohol Use Questionnaire, and Patient Health Questionnaire. Periodontal clinical attachment loss (CAL) of 3 mm or more and Patient Health Questionnaire-9 (PHQ-9) of 10 scores or more were used to identify periodontitis and depression, respectively. Daily alcohol consumption in the past year was classified into three levels: low (1 drink or less), moderate (between 1 and 3 drinks), and heavy drinking (4 drinks or more), while smoking was defined as having smoked at least 100 cigarettes in one's lifetime. Then, the logistic regression combined with interaction models were used to analyze the independent and combined effects of smoking, drinking and depression on periodontitis risk. RESULTS The results indicated a statistically significant multiplicative interaction between smoking and depression in relation to the development of periodontitis, both in the overall population (P = 0.03) and among male participants (P = 0.03). Furthermore, among individuals experiencing depression, smoking was found to significantly increase the prevalence of periodontitis by 129% in the younger age group compared to non-smokers (odds ratio [OR]: 2.29; 95% confidence interval [CI]: 1.10 to 4.76). However, the interaction between smoking and alcohol consumption was only significant among females (P < 0.05). There was a dose-dependent relationship between drinking frequency and smoking on periodontitis prevalence. In the smoking population, occasional drinking (OR: 1.70; 95% CI: 1.22 to 2.37) and regular drinking (OR: 2.28; 95% CI: 1.68 to 3.11) significantly increased the prevalence of periodontitis compared to individuals without these two factors. CONCLUSION These results suggested that there were interactive effects between smoking, drinking and depression on periodontitis risk and policies aimed at healthy behaviours and mental health may be beneficial for our oral health.

Abstract
BACKGROUND Periodontitis is closely associated with chronic systemic diseases. Healthy lifestyle interventions have health-enhancing effects on chronic systemic disorders and periodontitis, but the extent to which healthy lifestyle combinations are associated with periodontitis is unclear. Therefore, this study aimed to investigate the association between periodontitis and different healthy lifestyle combinations. METHODS 5611 participants were included from the National Health and Nutrition Examination Survey (NHANES, 2009-2014). Six healthy lifestyles factors were defined as fulfilling either: non-smoking, moderate drinking, moderate body mass index (BMI), physical activity, healthy sleep and appropriate total energy intake. Then, the adjusted logistic regression models were performed to identify the association between the periodontitis and the scoring system composed of six lifestyles (0-6 scale). Finally, different scenarios were dynamically and randomly combined to identify the optimal and personalized combination mode. RESULTS Higher healthy lifestyle scores were significantly associated with lower periodontitis prevalence (p < 0.05). Four lifestyle factors (smoking, drinking, BMI, and sleep) significantly varied between the periodontitis and healthy groups (p < 0.05). Smoking was considered as a strong independent risk factor for periodontitis in both former and current smokers. Results further indicated that the combination of these four lifestyles played the most essential role in determining the magnitude of periodontitis occurrence (odds ratio [OR]: 0.33; 95% confidence interval [CI]: 0.21 to 0.50). In the total population, the majority of three lifestyle combinations outperformed the two combination models, whereas the two-combination of nonsmoking-drinking (OR: 0.39; 95% CI: 0.27 to 0.58) had relatively lower periodontitis prevalence than the three-combination of healthy drinking-BMI-sleep (OR: 0.42; 95% CI: 0.26 to 0.66). CONCLUSION This cross-sectional study suggests that smoking, drinking, BMI, and sleep are significantly related with periodontitis and smoking is the principal risk factor related among them. This study provides various customized lifestyle combinations for periodontitis prevention.

Abstract
PURPOSE This study examined the protective effects and mechanism of Lycium barbarum polysaccharides (LBP) in the context of intestinal barrier function and intestinal microbiota in mice with dextran sulfate sodium (DSS)-induced chronic ulcerative colitis (UC). METHODS C57BL/6J male mice were assigned to a standard normal diet without DSS (control group), a normal diet with DSS (DSS group, 2% DSS given discontinuously for 3 weeks) or a normal diet supplemented with LBP (1% dry feed weight, LBP group, 2% DSS given discontinuously for 3 weeks) for a total of 8 weeks, at which point colonic tissues and caecal contents were collected. RESULTS LBP exerted a significant effect against colitis by increasing body weight, colon length, DAI and histopathological scores. LBP inhibited proinflammatory cytokines (IL-1β, IL-6, iNOS and TNF-α) expression, improved anti-inflammatory cytokine (IL-10) expression, promoted the expression of tight junction proteins (Occludin and ZO-1) via nuclear factor erythroid 2-related factor 2 (Nrf2) activation and decreased Claudin-2 expression to maintain the intestinal mucosal barrier. In addition, the abundances of some probiotics (Ruminococcaceae, Lactobacillus, Butyricicoccus, and Akkermansia) were decreased with DSS treatment but increased obviously with LBP treatment. And LBP reduced the abundance of conditional pathogens associated with UC (Mucispirillum and Sutterella). Furthermore, LBP improved the production of short-chain fatty acids (SCFAs), including acetic acid, propionic acid, butyric acid and isobutyric acid. CONCLUSION LBP can alleviate DSS-induced UC by regulating inflammatory cytokines and tight junction proteins. Moreover, LBP promotes probiotics, suppresses conditional pathogens and increases SCFAs production, showing a strong prebiotic effect.

Abstract
Seasonal influenza leads to a significant disease burden, and older people infected with influenza are susceptible to various complications. Influenza immunization can prevent infection effectively and significantly reduce the risk of complications and severe cases. Creating a supportive environment for vaccination is crucial in advancing the influenza vaccination rate among the elderly population. In China, the present environment for supporting influenza vaccinations among the elderly is primarily comprised of policies for free vaccination and expense reimbursement, which exhibit noteworthy regional variations across cities and regions. This study systematically analyses the supportive environment and regional disparities associated with influenza vaccination among the elderly in China. It aims to comprehend the opportunities for influenza prevention and control resulting from the current background of influenza vaccination and to identify potential health inequality challenges caused by regional differences. The findings should inform the introduction of relevant national policies and programs to protect the health and well-being of the elderly population.

Abstract
Honey bees are typical model organisms for the study of caste differentiation, and the juvenile hormone (JH) is a crucial link in the regulatory network of caste differentiation in honey bees. To investigate the mechanism of JH-mediated caste differentiation, we analyzed the effect of the JH response gene AmKr-h1 on this process. We observed that AmKr-h1 expression levels were significantly higher in queen larvae than in worker larvae at the 48 h, 84 h, and 120 h larval stages, and were regulated by JH. Inhibiting AmKr-h1 expression in honey bee larvae using RNAi could lead to the development of larvae toward workers. We also analyzed the transcriptome changes in honey bee larvae after AmKr-h1 RNAi and identified 191 differentially expressed genes (DEGs) and 682 differentially expressed alternative splicing events (DEASEs); of these, many were related to honey bee caste differentiation. Our results indicate that AmKr-h1 regulates caste differentiation in honey bees by acting as a JH-responsive gene.

Abstract
Objective: To explore the clinical outcomes of top-quality blastocysts transfer developed from cleavage embryos with different grading and determine whether the cleavage stage embryo morphology grading should be taken into consideration when transferring the embryo at the blastocyst stage. Methods: A number of 3 059 cycles were included with single top-quality blastocyst transfer dating from January 2017 to May 2021 in Henan Provincial People's Hospital. According to the number of cleavage sphere and degree of fragmentation, all cleavage stage embryos were divided into three groups: top D3 embryo (8 cells, ≤5% fragments)-TB group, suboptimal D3 embryo (8 cells, 5%<fragments≤10%; 7 cells or 9 cells, ≤10%)-TB group, and normal D3 embryo-TB group. Univariate analysis, multivariate logistic regression analysis and threshold effect analysis were performed on the data. Results: The clinical pregnancy rates of top D3 embryo-TB group(1 326 cycles), suboptimal D3 embryo-TB group (830 cycles) and normal D3 embryo-TB group (903 cycles) were 69.53%, 70.12% and 66.67%, respectively (P>0.05); and the early abortion rate were 10.74%, 12.54% and 12.62%, respectively (P>0.05). After adjusting for confounders, logistic regression showed that no significant associations were found between cleavage stage embryo morphology grading and clinical pregnancy rate (suboptimal D3 embryo-TB group: OR=1.02, 95%CI: 0.76-1.38, P=0.879; normal D3 embryo-TB group: OR=0.84, 95%CI: 0.61-1.14, P=0.262) and early abortion rate (suboptimal D3 embryo-TB group: OR=1.18, 95%CI: 0.77-1.82, P=0.445; normal D3 embryo-TB group: OR=1.26, 95%CI: 0.81-1.98, P=0.309). The results of threshold effect analysis showed that when a single top-quality blastocysts was transferred, the effect of age on the clinical pregnancy rate showed a curve relationship, when the age was≥33 years old, the clinical pregnancy rate decreased significantly with age increased (OR=0.89, 95%CI: 0.83-0.95, P=0.007); and there was no significant change in early abortion rate (OR=1.01, 95%CI: 0.97-1.06, P=0.628). Conclusions: Cleavage stage embryo grading is not found to correlate with clinical outcomes in single top-quality blastcyst tranfer. Therefore, when considering blastocyst transfer, its morphology at blastocyst stage is more relevant. The effect of age on pregnancy outcomes of single blastocyst transfer should be considered.

Abstract
Objective: To analyze the change trend of underground dust concentration, the incidence and survival status of pneumoconiosis patients, and provide reference for improving the working environment of dust-exposed workers and the prevention and treatment of pneumoconiosis patients in the future. Methods: In February 2020, a retrospective investigation was conducted on the dust data of underground mining operations in a steel enterprise in Jiangsu Province from 1991 to 2019, and the case data of patients diagnosed with pneumoconiosis from 1956 to 2019 were collected. The time trends of the number of pneumoconiosis patients and dust concentration, the stage of pneumoconiosis and survival status of patients were analyzed. Results: From 1956 to 2019, a total of 241 patients with pneumoconiosis were diagnosed in the steel enterprise. From 1991 to 2019, the annual average dust concentration in the mine showed a downward trend as a whole. Compared with the transportation platform (14.28%, 1447/10132) , the average dust concentration exceeding rate of the mining platform (43.68%, 8415/19263) was significantly higher (χ(2)=2674.84, P<0.01) . The average age of pneumoconiosis patients was (73.54±10.42) years old, and the average working age of dust exposure was (21.41±8.68) years, of which 85 cases (35.27%) survived and 156 cases (64.73%) died. The main type of pneumoconiosis was silicosis (90.46%, 218/241) , and the main stage of pneumoconiosis was the stage I (96.68%, 233/241) ; The higher the stage of pneumoconiosis, the younger the diagnosis age (P<0.01) . The average survival time of patients was (27.264±1.982) years, and the median survival time was 28 years. The cumulative survival rates of patients with pneumoconiosis in different diagnosis time periods were significantly different (χ(2)=35.57, P<0.01) . Conclusion: The improved dust-proof measures have a significant effect on reducing the concentration of underground dust. We need to focus on the dust control of underground mining platforms and the treatment of patients with stage Ⅲ pneumoconiosis.

Abstract
Objective: To investigate the expression and clinical significance of neutrophil myeloperoxidase (MPO) in patients with MPO-antibody associated vasculitis (AAV). Methods: Thirty-six newly diagnosed MPO-AAV patients who were hospitalized in the First Affiliated Hospital, Anhui Medical University from July 2018 to June 2021 were enrolled,and 36 age and sex matched healthy subjects were selected as controls. Neutrophil MPO level was detected by flow cytometry (FCM) and MPO mRNA was tested by real time quantitative polymerase chain reaction (RT-qPCR) in all subjects. Serum complement fragment C5 (C5a) and MPO in both groups and serum MPO-anti-antineutrophilic cytoplasmic antibody(ANCA) in MPO-AAV group were measured by enzyme linked immunosorbent assay (ELISA), while the disease activity was evaluated by Birmingham vasculitis activity score-V3 (BVAS-V3). Results: Compared with the heathy control group, the expression of MPO mRNA in neutrophils, serum MPO and complement C5a in MPO-AAV group were significantly higher[MPO mRNA:30.2±11.5 vs. 1.9±0.6, P<0.001;MPO:(112.0±68.7) IU/L vs. (87.4±22.9) IU/L, P=0.01; C5a:(187.3±90.3) ng/ml vs. (107.3±31.1) ng/ml, P<0.001; respectively], while the mean fluorescence intensity (MFI) of MPO in neutrophils were significantly lower [ 1 343.3±723.4 vs. 2 868.0±1 136.5, P<0.001]. In MPO-AAV group, the expression of neutrophil MPO mRNA was positively correlated with serum MPO-ANCA and MPO levels (r=0.537, P=0.001 and r=0.358, P=0.032; respectively). Multiple regression analysis suggested that neutrophil MPO mRNA expression was positively correlated with serum MPO-ANCA level (β=0.695, P=0.006); neutrophil MPO level was negatively correlated with serum MPO-ANCA, MPO and complement C5a levels (r=-0.335, P=0.046; r=-0.372, P=0.026; r=-0.577, P<0.001; respectively). Further, neutrophil MPO level was negatively correlated with serum complement C5a level (β=-0.374, P=0.043). BVAS-V3 was positively correlated with MPO mRNA expression in neutrophils, serum MPO-ANCA, MPO and complement C5a (r=0.598, P<0.001; r=0.599, P<0.001; r=0.537, P=0.001; r=0.415, P=0.012; respectively) and negatively correlated with MPO level in neutrophils (r=-0.342, P=0.041). In multiple regression analysis it suggested that BVAS-V3 was positively correlated with MPO mRNA expression in neutrophils (β=0.511, P=0.002). Conclusion: In MPO-AAV patients, MPO synthesis and release in neutrophils are both significantly increased, which might be influenced by serum MPO-ANCA and C5a, respectively. Furthermore, MPO synthesis activity in neutrophils is an independent factor related to disease activity.

Abstract
Objective: To investigate the current situation of safety protection of medical staffs in medical institutions in Jiangsu Province, and to provide scientific basis for strengthening the safety protection of infectious diseases and protecting the occupational health of medical staffs. Methods: From September to October 2020, 1274 medical staffs in 43 medical and health institutions were randomly selected as the subjects. The self-made questionnaire for infectious disease prevention and protection was used to analyze the pre-job training and exposure to occupational harmful factors of the respondents. The influencing factors of using protective equipment and occupational injury were analyzed by binary logistic regression. Results: A total of 1216 valid questionnaires were collected with effective recovery of 95.4%. There were 312 males (25.7%) and 904 females (74.3%) , with an average age of (35.8±9.2) years and average working years of (13.6±9.9) years. Among them, 1143 (94.0%) had participated in pre-job training, 535 (44.0%) thought they were exposed to occupational harmful factors of infectious disease prevention, 1082 (89.0%) used protective equipment in daily operation, and 462 (38.0%) had occupational injury. According to binary logistic regression analysis, the utilization rates of protective equipment for medical staffs in Centers for Disease Control and Prevention (OR=2.473, 95%CI: 1.327-4.607, P=0.004) , 30-39 years old (OR=1.586, 95%CI: 1.038-2.426, P=0.033) , 40-49 years old (OR=2.257, 95%CI: 1.243-4.098, P=0.007) , 50 years old and above (OR=5.879, 95% CI: 1.755-19.692, P=0.004) and pre-job training (OR=2.580, 95%CI: 1.301-5.116, P=0.007) were higher than their respective control groups. And medical staffs with graduate degree or above (OR=0.342, 95%CI: 0.167~0.699, P=0.003) had lower utilization rate of protective equipment. Female (OR=1.902, 95%CI: 1.364-2.654, P<0.001) , 30-39 years old (OR=1.589, 95%CI: 1.157-2.181, P=0.004) , bachelor degree (OR=2.070, 95%CI: 1.419-3.021, P<0.001) , exposure to occupational harmful factors (OR=2.753, 95%CI: 2.086-3.634, P<0.001) were the risk factors for occupational injury of medical staffs. Centers for Disease Control and Prevention (OR=0.129, 95%CI: 0.086-0.194, P<0.001) and wearing protective equipment according to regulations (OR=0.597, 95%CI: 0.431-0.827, P=0.002) were the protective factors for occupational injury of medical staffs. Conclusion: At present, the occupational injury rate of medical staffs in Jiangsu Province is high due to various factors in the prevention and control of infectious diseases. It is necessary to pay attention to occupational safety protection, strengthen pre-job training and actively advocate "standard prevention", so as to reduce the exposure risk of harmful factors and promote occupational health of medical staffs.

Abstract
BACKGROUND The primary objective of the study was to discuss the sex differences in insulin resistance-induced changes in metabolic and inflammatory markers in school-aged children with overweight and obesity. METHODS A cross-sectional study of 800 children aged seven and twelve years was performed. Questionnaires, anthropometric data and fasting blood samples were collected. RESULTS Children with overweight and obesity showed statistically significant differences in multiple metabolic and inflammatory markers compared with children with normal BMI. The correlation coefficient (r) between white blood cell count, absolute neutrophil count, fasting plasma insulin, HOMA-IR, HOMA-β, triglyceride, HDL-C, triglyceride/HDL ratio, alanine transaminase, serum uric acid, systolic blood pressure and BMI were higher in all children, but the linear relationships between white blood cell count, absolute neutrophil count and BMI were stronger in girls with overweight and obesity than in boys with overweight and obesity. Subsequently, HOMA-IR was shown to be more strongly associated with increased white blood cell count and absolute neutrophil count in school-aged girls with overweight and obesity by partial correlation analysis and the multiple linear regression analysis. CONCLUSIONS Elevated white blood cell count and absolute neutrophil count in children with overweight and obesity, especially girls, can serve as markers of insulin resistance.

Abstract
Objective: To discuss the new idea of on-the-spot recompression treatment and multidisciplinary treatment (MDT) for patients with unstable vital signs of type II decompression sickness. To provide reference for the nearby treatment of patients with critical decompression sickness. Methods: The clinical data of a case of a multi-disciplinary collaborative treatment of type II decompression sickness complicated with multiple organ dysfunction syndrome (MODS) admitted to a third-class A hospital in January 2020 were analyzed and summarized. Results: The patient suffered from consciousness disturbance and shock after 3 min of diver's blow-up out of the water. CT examination showed gas accumulation in the systemic multi-organ venous system, and laboratory examination suggested MODS. The oxygen inhalation regimen was given in the session of recompression treatmen by 0.12-0.18 MPa. Intravenous fluid was the total of 8900 ml in the session, and the total recompression treatment time was 9 h 45 min. The patient was still in unconscious when he finished the session. CT re-examination confirmed the elimination of venous bubbles, and laboratory examination indicated multiple organ failure (MOF) . The patient was given comprehensive supporting treatment by mechanical assisted breathing and following by continuons renal replacement therapy (CRRT) and extrocorporeal membrane oxygenation (ECMO) in the intensive care unit, and was discharged after 32 d of hospitalization. Conclusion: Critical decompression sickness patients with unstable vital signs are taken to a local general hospital with hyperbaric oxygen chamber and intensive care unit. The successful treatment can be achieved by organizing diving medicine, hyperbaric oxygen medicine and critical medical personnel for MDT.

Abstract
The design of a highly adhesive, defect-free and low-temperature sol-gel coating for the protection of magnesium alloys is desirable yet challenging. In this study, a novel SiO2-based sol-gel coating is developed by a ring-opening addition reaction. Notably, the integration of individual sol clusters endows the sol-gel coating with a smooth and compact surface morphology, and eliminates the potential corrosion site of the low-temperature-prepared sol-gel coating. Besides, the as-obtained sol-gel coating exhibits excellent metallic adhesion nature. Most importantly, it increases the overall impedance modulus by 27 times than that of the conventional strategy and decreases the corrosion rate from 3.8 ± 0.5 mg cm-2 per day (commercial chromate conversion coating) to 0.5 ± 0.2 mg cm-2 per day.

Abstract
Recent years, national laws and government policies were published as series to encourage the development of group standardizations. The updated Standardization Law of the People's Republic of China, implemented on January 1(st), 2018, stipulates that group standard is a part of the Chinese standard system. Under the current supportive circumstances, more institutes and organizations have joined in the writing and releasing procedures of group standards'. Despite the rapid development of group standardization to publish, we are still at the phase of exploring and regulating group standardizations. This review summarizes the development and practice on the development group standardization in the Chinese Preventive Medicine Association and analyzes current condition and deficiency of the work in China, in order to develop suggestions and strategies to improve and regulate group standardization.

Abstract
Objective: To evaluate the effect of multimodal analgesia using periprostatic nerve block anesthesia (PNB) combined with flurbiprofen in patients undergoing transperineal template-guided prostate biopsy (TTPB). Methods: Totally 166 patients (aged (68.2±9.1) years, range: 47 to 81 years) who received TTPB from October 2017 to June 2018 at Department of Urology, Northern Jiangsu People's Hospital Affiliated to Yangzhou University were enrolled prospectively. All the patients were randomly divided into 2 groups. The observation group (n=79) was given flurbiprofen axetil 1 mg/kg intravenously for half an hour before operation and lidocaine was used for PNB before the biopsy. The control group (n=87) was given normal saline combined with PNB. A visual analog scale (VAS) and visual numeric scale (VNS) were used to assess the patients' pain and quantify their satisfaction at two time points: VAS-1 and VNS-1: during biopsy procedure, VAS-2 and VNS-2: 30 min after the procedure. The date were compared by t test, χ(2) test, Fisher exact test and two-way repeated measures anova analysis between the 2 groups. Results: The age, total prostate volume, serum prostate-specific antigen and the number of cores were comparable among the 2 groups (P>0.05). The VAS-1 scores of the control group and the observation group were 2.8±1.7, 1.9±1.2, respectively, and the VNS-1 were 3.1±0.7, 3.4±0.3, respectively. The VAS-1 were significantly lower in observation group than in control group (F=3.904, P=0.000). Conversely, the VNS-1 were higher in observation group (F=3.526, P=0.000). At 30-minute postoperative, the VAS-2 and VNS-2 were 0.7±0.4 and 3.7±0.2 in the control group, respectively. The VAS-2 and VNS-2 were 0.6±0.5 and 3.8±0.1 in the observation group, respectively. There were no significant differences in the pain scores or the satisfaction scores between the 2 groups (F=1.429, 2.825; P=0.136, 0.083). The incidence of overall complications was 26.4% (23/87) in the control group and 25.3% (20/79) in the observation group, with no statistical difference between the 2 groups (χ(2)=0.027, P=0.869). And the complications had no statistically significant difference among the 2 groups including hematuria, urinary retention, infection, hematospermia, vascular and neurological reactions, nausea, vomiting, dizziness, headache, and respiratory depression (P>0.05). Conclusion: The multimodal analgesia induced by PNB and flurbiprofen could effectively relieve the pain for patients who received TTPB.

Abstract
Post-traumatic stress disorder (PTSD) is a serious psychiatric disorder. Estazolam has been shown to produce anxiolytic-, hypnotic-, amnestic-, and sedative-like effects. However, few studies are concerned about its anti-PTSD-like effects. The anti-PTSD-like effects of estazolam were evaluated by single prolonged stress animal model. After exposure to single prolonged stress, rats (Sprague-Dawley, male, 8 weeks) were administered by estazolam (0.5, 1 and 2 mg/kg, i.p.) from day 2 to 13 once daily. The behavioral assessments were performed during treatment with drugs. After the behavioral evaluation, the role of allopregnanolone in the anti-PTSD-like effects of estazolam was also evaluated via astrocyte cells and brain tissues (e.g. prefrontal cortex, hippocampus, and amygdala). The PTSD-like behavioral deficits were significantly blocked by estazolam (1 and 2 mg/kg, i.p.) without affecting locomotor activity. Consistently, the levels on allopregnanolone were increased by estazolam (1 and 2 mg/kg, i.p.) in prefrontal cortex, hippocampus, and amygdala. The levels of allopregnanolone were increased by sertraline (1 µmoL/L) and estazolam (4 µmoL/L), while the effects were antagonized by trilostane (1 µmoL/L) and finasteride (1 µmoL/L) in astrocyte cells, respectively. Collectively, the anxiety-like behavior deficits were ameliorated by estazolam in the single prolonged stress animal model that was associated with biosynthesis of allopregnanolone.

Abstract
Objective: To explore the effect of occupational exposure to glyphosate on hepatorenal function. Methods: 526 workers who were occupationally exposed to glyphosate from 5 glyphosate-producing factories were selected as cases; and another 442 administrative staffs who were not exposed to glyphosate were selected as controls from April to November, 2014. All the subjects accepted occupational health examination. The concentration level of glyphosate in the air of workshop was detected and the time weighted average concentration (TWA) was calculated. And analyze the difference of hepatorenal fuction between case group and control group. Result: The age of the subjects in the case and control groups were separately (35.6±10.3), (34.3±9.7) years old, with the length of working for (6.5±5.7), (7.7±6.8) years. The TWA of glyphosate in the case group was between <0.03-48.91 mg/m(3), with the geometric mean at 3.78 mg/m(3). The overall rates of abnormal hepatic and renal function in the case group were 14.4% (76 cases) and 16.2% (85 cases), respectively; while those were 5.0% (22 cases) and 4.8% (21 cases), respectively in control group, and the difference showed statistical significance (P<0.05). When TWA reached <0.03-6.00 mg/m(3), the difference of hepatorenal fuction between case group and control group showed statistical significance, and the rates of abnormal hepatic and renal function was 8.0% (36/447) and 9.8% (44/447) respectively in case group. When cumulative exposure level reached <1.56-68.64 g, the difference of hepatorenal fuction between case group and control group showed statistical significance, and the rates increased to 9.2% (37/404) and 10.4% (42/404) respectively in group of cases. Conclusion: Glyphosate can affect the hepatic and renal function among occupational exposure population, and there was an association between the effect and the exposure dose.

Abstract
Objective: To investigate and analyze the influential factors of occupational hazard acci-dents, emergency facilities and emergency management in Silicon solar cell producing enterprises, then to pro-vide scientific strategies. Methods: The methods of occupationally healthy field investigating, inspecting of ven-tilation effectiveness, setup of emergency program and wearing chemical suit were used. Results: The mainly occupational hazard accidents factors in the process of Silicon solar cell producing included poisoning chemi-cals, high temperature, onizing radiation and some workplaces. The poisoning chemicals included nitric acid, hydrofluoric acid, sulfuric acid, hydrochloric acid, sodium hydroxide, potassium hydroxide, chlorine, phos-phorus oxychloride, phosphorus pentoxide, nitrogen dioxide, ammonia, silane, and so on; the workplaces in-cluded the area of producing battery slides and auxiliary producing area. Among the nine enterprises, gas detec-tors were installed in special gas supplying stations and sites, but the height, location and alarmvalues of gas detectors in six enterprises were not according with standard criteria; emergency shower and eyewash equip-ment were installed in workplaces with strong corrosive chemicals, but the issues of waste water were not solved; ventilation systems were set in the workplaces with ammonia and silane, but not qualified with part lo-cations and parameters in two enterprises; warehouses with materials of acid, alkali, chemical ammonia and phosphorus oxychloride were equipped with positive - pressure air respirator resuscitator and emergency cabi-nets, but with insufficient quantity in seven enterprises and expiration in part of products. The error rate of set-up emergency program and wearing chemical cloth were 30%~100% and 10%~30%, respectively. Among the nine enterprises, there were emergency rescue plans for dangerous chemical accidents, but without profession-al heatstroke and irradiation accident emergency plans, lack of archives of descripting and evaluating for pro-cessing in emergency exercises as well. There were emergency rescue agreements between enterprises and medi-cal institutions which varied in occupational poisoning rescue capacities and were lack of training and exercise regularly. Conclusion: There were a variety of occupational hazard factors in Silicon solar cell producing enter-prises including potential chemical burns, acute poisoning, occupational heatstroke, accident risk of ionizing radiation, and we must strengthen the management of emergency rescue for Silicon solar cell producing enter-prises.

Abstract
Vitamin K epoxide reductase (VKOR) exists widely in the chloroplasts of higher plants and plays important roles in redox regulation. However, investigations of plant VKOR function have primarily focused on VKOR from Arabidopsis, and knowledge concerning this function is therefore quite limited. In this study, Solanum lycopersicum was used to study the function of VKOR. Transcription level analysis revealed that SlVKOR (S. lycopersicum VKOR) expression was upregulated by salt or drought stress. To further investigate the function of SlVKOR in plants, we generated sense and antisense transgenic S. lycopersicum homozygotes at T2 generation plants. Compared with wild-type (WT) plants, the leaf disks of the SlVKOR overexpression plants retained a much higher percentage of chlorophyll after salt or drought treatment, whereas the antisense transgenic plants displayed an opposite response. The overexpressed plants displayed lower levels of H2O2 and superoxide anion radical (O2(·-)) than WT plants, whereas antisense plants accumulated considerably more H2O2 and O2(·-). The activities of reactive oxygen scavenger enzymes, including superoxide dismutase, peroxidase, ascorbate peroxidase and catalase, were consistent with the accumulation of reactive oxygen species. Based on these results, we suggest that SlVKOR is involved in resistance to salt or drought stress.

Abstract
Tubby-like proteins (TLPs), which have a highly conserved β barrel tubby domain, have been found to be associated with some animal-specific characteristics. In the plant kingdom, more than 10 TLP family members were identified in Arabidopsis, rice and maize, and they were found to be involved in responses to stress. The publication of the apple genome makes it feasible to systematically study the TLP family in apple. In this investigation, nine TLP encoding genes (TLPs for short) were identified. When combined with the TLPs from other plant species, the TLPs were divided into three groups (group A, B, and C). Most plant TLP members in group A contained an additional F-box domain at the N-terminus. However, no common domain was identified other than tubby domain either in group B or in group C. An analysis of the tubby domains of MdTLPs identified three types of conserved motifs. Motif 1 and 2, the signature motifs in the confirmed TLPs, were always present in MdTLPs, while motif 3 was absent from group B. Homology modeling indicated that the tubby domain of most MdTLPs had a closed β barrel, as in animal tubby domains. Expression profiling revealed that the MdTLP genes were expressed in multiple organs and were abundant in roots, stems, and leaves but low in flowers. An analysis of cis-acting elements showed that elements related to the stress response were prevalent in the promoter sequences of MdTLPs. Expression profiling by qRT-PCR indicated that almost all MdTLPs were up-regulated at some extent under abiotic stress, exogenous ABA and H2O2 treatments in leaves and roots, though different MdTLP members exhibited differently in leaves and roots. The results and information above may provide a basis for further investigation of TLP function in plants.

Abstract
CONTEXT Endometriosis is an estrogen-dependent disease. P38 and C-jun NH2-terminal kinase (JNK) inhibitors may have a therapeutic effect on endometriosis through regulation of prostaglandin E2 (PGE2)-induced estrogen metabolism. OBJECTIVE The objective of this study was to determine whether the activated MAPKs signaling pathway observed in human ectopic endometrial stromal cells (ESCs) from ovarian endometriomas influences levels of aromatase and estrogen receptor β (ERβ) protein regulated by PGE2. In turn, the effects of inhibiting MAPKs in the presence of PGE2 on estrogen production were investigated in vitro and in vivo. RESULTS Expression of aromatase and ERβ regulated by PGE2 were much higher in ESCs than eutopic ESCs from the same person. Activation of p38, JNK, ERK 1/2 and ERK 5 MAPKs by PGE2 were observed in ESCs, where PGE2-stimulated aromatase and ERβ expression mainly through p38 and JNK pathway. P38 and JNK inhibition or small interfering RNA knockdown blocked PGE2-induced aromatase and ERβ expression. PGE2 enhanced binding of downstream p38 and JNK transcription factors activating transcription factor-2 and c-Jun to aromatase and ERB promoter regions in ESCs. Moreover, treatment of endometriosis xenografts with inhibitors of p38 and JNK abrogated PGE2-amplified estradiol synthesis and xenograft growth. CONCLUSIONS PGE2 activates p38 and JNK signaling pathways, further stimulating c-Jun and activating transcription factor-2 binding to aromatase and ERB promoter regions with elevated estradiol production. Inhibition of JNK and P38 may be a potential method of treating human endometriosis.

Abstract
Many proteins in chloroplast are regulated through the disulfide bond/thiol transformation to realize their activities. A homologue of VKOR (Vitamin K epoxide reductase) in Arabidopsis chloroplast is found to catalyze the disulfide bond formation in vivo and to mediate the specific phylloquinone reduction in vitro. It is also called LTO1 (Lumen Thiol Oxidoreductase 1). Investigations about functions and essential amino acid residues of AtVKOR have important theoretical significance to clarify the chloroplast redox regulation mechanism. In this study, several amino acids in the VKOR domain of AtVKOR were identified to be involved in binding of phylloquinone. Site-directed mutagenesis was used to study the function of these positions. The results suggested that residues Ser77, Leu87, Phe137 and Leu141 were quite important in the binding and catalyzing the reduction of phylloquinone. These residues were also involved in the electron transferring and disulfide bond formation of substrate proteins by motility assays in vivo, suggesting that the binding of phylloquinone not only affected the delivery of electrons to phylloquinone but also affected the whole electron transfer process. The conserved cysteines in the AtVKOR domain also played critical roles in phylloquinone reduction. When each of the four conserved cysteines was mutated to alanine, the mutants lost reduction activity entirely, suggesting that the four conserved cysteines played crucial roles in the electron transfer process.

Abstract
BACKGROUND Cytochrome P450 aromatase (encoded by the CYP19A1/aromatase gene) plays a critical physiologic role in endometriosis. Metformin is known to suppress prostaglandin E2 (PGE2)-induced CYP19A1 messenger RNA (mRNA) expression in human endometriotic stromal cells (ESCs). However, the possible mechanism behind this suppression remains to be determined. METHODS In this study, ESCs were cultured with metformin, PGE2, and adenosine monophosphate (AMP)-activated protein kinase (AMPK) inhibitors. Expression of CYP19A1 mRNA and aromatase activity were measured by quantitative polymerase chain reaction and aromatase activity assay, respectively. The binding of the cyclic AMP response element-binding (CREB) protein to CYP19A1 promoter II (PII) was assessed by chromatin immunoprecipitation assay. RESULTS We demonstrated that metformin downregulated the expression of aromatase mRNA (32%) and activity (25%) stimulated by PGE2 (4.18-fold and 2.14-fold) in ESCs via stimulation of AMPK. Following PGE2 treatment, there was a marked increase in CREB binding to aromatase PII, while metformin attenuated the above-mentioned stimulation by 67%. CONCLUSION Metformin could inhibit PGE2-induced CYP19A1 mRNA expression and aromatase activity via AMPK activation and inhibition of CREB to CYP19A1 PII in human ESCs. The results of the present study suggest that metformin may have unique therapeutic potential as an antiendometriotic drug in the future.

Abstract
Arabidopsis lumen thiol oxidoreductase 1 (LTO1) - the At4g35760 gene product - was previously found to be related to reactive oxygen species (ROS) accumulation. Here, we show that ROS accumulated in a mutant Arabidopsis line (lto1-2, mutant of LTO1/AtVKOR) under osmotic stress at a higher level than that observed in wild-type and transgenic complemented plants of the lto1-2 mutant (lto1-2C, transgenic complemented plants of lto1-2). Because ROS accumulation in osmotic stress is triggered by abscisic acid (ABA), an ABA-responsive gene, Annexin 1 (AnnAt1), was selected to study the response. Osmotic stress or exogenous ABA can significantly upregulate the transcription of AnnAt1 in wild-type and lto1-2C plants. Only a slight change in the transcriptional abundance of AnnAt1 was observed under osmotic stress in the lto1-2 mutant, but exogenous ABA application could increase the expression of AnnAt1, which suggested that exogenous ABA had a partial complementation role. Because the transcription of AnnAt1 is regulated by ABRE (ABA-responsive elements) binding proteins (AREBs)/ABRE binding factors (ABFs), the expression of AREBs/ABFs was also analyzed. The transcription of AREBs/ABFs in the lto1-2 mutant was not induced by osmotic stress but was significantly upregulated by exogenous ABA, which significantly differs from the wild-type and lto1-2C plant responses. Similarly, the expression of another ABA-responsive gene, RD29B (responsive to desiccation stress gene 29B), in the lto1-2 mutant was also upregulated by exogenous ABA. The partial complementation of mutants by ABA indicated that the ABA signal transduction pathway was not significantly affected in the lto1-2 mutant. Taken together, these results suggest that LTO1 is involved in ABA-mediated response to osmotic stress, possibly by affecting the biosynthesis of endogenous ABA.

Abstract
CONTEXT Endometriosis is an estrogen-dependent disease affecting reproductive women. Metformin could have a therapeutic effect on endometriosis through regulation of local estrogen production. OBJECTS The aim of this study was to investigate the molecular and cellular mechanism by which metformin regulates StAR expression in human endometriotic stromal cells (ESCs). METHODS ESCs derived from ovarian endometriomas were cultured with metformin and prostaglandin E2 (PGE2). StAR mRNA was measured by quantitative PCR; pregnenolone, progesterone, and estrogen production were measured by ELISA kits; steroidogenic acute regulatory protein (StAR), AMP-activated protein kinase, cAMP response element binding protein (CREB), and CREB-regulated transcription coactivator 2 (CRTC2) protein expression were measured by Western blot assay; and CRTC2 translocation and its association with CREB were assessed by coimmunoprecipitation assay and CRTC2-CREB complex binding by a chromatin immunoprecipitation assay. RESULTS 1) StAR mRNA levels in ESCs are 264 times higher than those in endometrial cells. 2) Metformin downregulates the StAR mRNA expression (maximum 31.7%) stimulated by PGE2 (2.4-fold) in ESCs. 3) PGE2 induces CRTC2 translocation and enhances its association with CREB to form a transcription complex that binds to the StAR promoter region. 4) Metformin prevents the nuclear translocation of CRTC2 by increasing AMP-activated protein kinase phosphorylation. This inhibits transcription of StAR by disrupting formation of the CREB-CRTC2 complex, involved in activation of the StAR promoter cAMP response element. CONCLUSIONS We have demonstrated a detailed mechanistic analysis of StAR expression regulated by metformin in ESCs. Our data highlight a role for CRTC2 in the mechanism by which metformin inhibits StAR expression.

Abstract
This study aimed to explore the interaction and crosstalk between pathways in response to destrin mutations. All the pathways from the MINT database were downloaded, a protein-protein interaction network was then constructed, and the crosstalk between pathways was investigated, in particular, the overlap of 2 significant pathway analysis results. As expected, the results showed that regulation of the actin cytoskeleton was the significant pathway of destrin mutations in mice. Further analysis indicated that 28 significant pathways cross-talked with the pathway regulating the actin cytoskeleton. Importantly, 3 pathways, including regulation of actin cytoskeleton pathway, pathways in cancer, and the B cell receptor signaling pathway were linked by inositol phosphate metabolism based on crosstalk analysis of Gene Ontology relationships among pathways. All of these pathways have been demonstrated to participate in cytoskeleton dynamics. These findings might provide valuable insights into cytoskeleton dynamic abnormalities in destrin mutations of corneal diseases.
