Abstract
Objective: To analyze the characteristics of the ocular vestibular evoked myogenic potential on three different eye positions and to explore the appropriate eye position for oVEMP. Methods: 15 patients (30 ears) with vertigo who underwent oVEMP test from December 2017 to May 2018 were selected as the patient group, including seven males and eight females, with an average age of (51±13) years. Another 22 (44 ears) healthy young people were recruited into the control group, including 10 males and 12 females, with an average age of (23±5) years. oVEMPs were measured on the following three eye positions respectively: 30 degrees straight up(upper median position),45 degrees upper right(upper right position), and 45 degrees upper left(upper left position). oVEMP elicitation rate, oVEMP latencies, amplitudes and interaural amplitude asymmetry ratio were analyzed by SPSS 23.0 statistical software. Results: There was no statistical significance (P>0.05) in the oVEMP elicitation rate, oVEMP latency, amplitude and asymmetry ratio on the three eye positions among the control group, the patient group and the overall subjects. Conclusions: The three eye positions can be used to detect oVEMP in clinic. There is no difference in the extraction rate and waveform characteristics. When one of the eye positions is difficult to gaze or not easy to obtain the coincidence curve, the other two can be used to obtain the ideal oVEMP curves as well.

Abstract
This study was conducted to investigate the effects of dietary bamboo leaf extract (BLE) on growth performance, meat quality, oxidative stability, and nuclear factor erythroid 2-related factor 2 (Nrf2) related gene expression of breast meat in broilers. A total of 576 one-day-old male Arbor Acres broilers were divided into 6 groups. The control group (CTR) was fed basal diet, while BLE1, BLE2, BLE3, BLE4, and BLE5 were fed basal diet supplemented with 1.0, 2.0, 3.0, 4.0, and 5.0 g BLE per kg feed, respectively. Compared with the CTR group, BLE2 and BLE5 increased average daily feed intake from 1 to 21 D and 22 to 42 D (P < 0.05), BLE1 and BLE2 improved average daily gain (ADG) and feed to gain ratio from 22 to 42 D (P < 0.05). Throughout the trial period, the highest body weight and favorable ADG and feed to gain ratio were observed in the BLE2 group. The drip loss at 24 h and pH at 45 min postmortem of breast meat were linearly improved by BLE supplementation (P < 0.05). Shear force was significantly lower in BLE2 and BLE3 than that in CTR group. Increasing supplementation of BLE linearly improved free radical scavenging capacity and decreased malondialdehyde content of breast meat during 12 D of storage (P < 0.05). Total antioxidant capacity and glutathione peroxidase activity were linearly increased by BLE supplementation (P < 0.05). Compared with the CTR group, the mRNA expression of Nrf2 and glutathione peroxidase in BLE3, BLE4, and BLE5 groups was significantly promoted, and glutathione S-transferase gene expression was increased in BLE2, BLE4, and BLE5 (P < 0.05). The highest (P < 0.05) heme oxygennase-1 gene expression was observed in BLE5. In conclusion, broiler supplemented with BLE improved growth performance and meat quality, BLE supplementation might activate Nrf2 pathway to alleviate lipid oxidation and increase antioxidant capacity of breast meat. The dosage of 2.0 to 3.0 g/kg BLE in broiler diet was recommanded.

Abstract
Objective: To investigate the relationship between exposure to famine in fetus and infant period and the risks for hypertension in adulthood. Methods: A total of 5 960 participants born between 1956 and 1965 were included in the study and were divided into unexposed group (1963-1965), fetal exposed group (1959-1961), early- childhood exposed group (1956-1958) and transitional group (1962). Logistic regression model was used to explore the association between famine exposure in early life and the risk for hypertension in adulthood. Results: Both the fetal exposure and the early-childhood exposure were the risk factors for hypertension in adulthood (OR=1.249, 95%CI: 1.049-1.486 and OR=1.360, 95%CI: 1.102-1.679). Meanwhile, in rural area, compared with unexposed group, the fetal exposure (OR=1.401, 95%CI: 1.091-1.798) and the early-childhood exposure (OR=1.460, 95%CI: 1.145-1.862) were also associated with a greater risk of hypertension in adulthood. In addition, fetal exposure and early-childhood exposure to famine in women were associated with 36.0% and 31.9% increased risks for hypertension (95%CI: 7.8%-71.7% and 95%CI: 4.8%-66.0%) according to the stratified analysis. Conclusion: Fetal exposure to famine might increase the risk for hypertension in adulthood.

Abstract
Objective: To observe the difference of pulmonary function among patients with dysphagia after stroke, patients without dysphagia and normal people, and to explore the correlation between swallowing function and pulmonary function. Methods: From September 2018 to April 2019, 310 stroke patients were enrolled from the rehabilitation department and neurology department of sun yat-sen memorial hospital, sun yat-sen university, of which 60 were selected as standard stroke patients. Pulmonary function of the three groups was assessed by pulmonary function detector and further compared. The swallowing function of the dysphagia group after stroke was examined by using videofluroscopic swallowing study (VFSS). The swallowing function was quantitatively assessed by Rosenbek penetration-aspiration scale (PAS), dysphagia outcome and severity scale (DOSS) and videofluoroscopy dysphagia scale (VDS), and the correlation between swallowing function and respiratory function was analyzed. Results: There were significant differences in pulmonary function among three groups (P<0.05). Besides the FEF25,FVC, FIVC between patients with dysphagia after stroke and patients without dysphagia, the FEF75 between patients without dysphagia and normal people (all P>0.05), there were significant differences in the pairwise comparison of other indicators (all P<0.05). There were correlations between PAS and MIP (r=-0.618, P=0.001),PAS and MEP (r=-0.410, P=0.038), PAS and PEF (r=-0.443, P=0.024), DOSS and MIP (r=0.602, P=0.000),DOSS and MEP (r=0.496, P=0.005), DOSS and PEF (r=0.553, P=0.002), VDS and MEP (r=-0.483, P=0.012),VDS and PEF (r=-0.494, P=0.010), respectively. Conclusion: The pulmonary function of dysphagia patients after stroke decrease significantly, and the severity of dysphagia is correlated with the decrease of pulmonary function.

Abstract
Recently, bromodomain-containing protein 9 (BRD9) has been a prospective therapeutic target for anticancer drug design. Molecular dynamics (MD) simulations combined with molecular mechanics generalized Born surface area (MM-GBSA) method were adopted to explore binding modes of three inhibitors (5SW, 5U2, and 5U6) to BRD9 and identify the hot spot of the inhibitor-BRD9 binding. The results indicate that the inhibitor 5SW has the strongest binding ability to BRD9 among the current three inhibitors. Furthermore, the rank of the binding free energies predicted by MM-GBSA approach agrees with that determined by the experimental values. In addition, inhibitor-residue interactions were computed by using residue-based free-energy decomposition method and the results suggest that residue His42 produces the CH-H interactions, residues Asn100, Ile53 and Val49 produce the CH-[Formula: see text] interactions with three inhibitors and Tyr106, Phe45 and Phe44 generate the π-π interactions with inhibitors. Notably, the residue Asn140 forms hydrogen bonding interactions with three inhibitors. This research is expected to provide useful molecular basis and dynamics information at atomic levels for the design of potent inhibitors inhibiting the activity of BRD9.

Streptomyces-derived actinomycin D inhibits biofilm formation via downregulating ica locus and decreasing production of PIA in Staphylococcus epidermidis. J Appl Microbiol 2019; 128:1201-1207. [PMID: 31808241 DOI: 10.1111/jam.14543] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2019] [Revised: 11/12/2019] [Accepted: 12/03/2019] [Indexed: 11/26/2022]
Abstract
AIM The objective of this study was to investigate the biofilm inhibitory activity of Streptomyces-derived actinomycin D against biofilm formation by Staphylococcus epidermidis. METHODS AND RESULTS The microtitre plate method and microscopy were used to detect the biofilm formation of S. epidermidis. And an attempt was made to detect the effect of actinomycin D on important biofilm components, exopolysaccharides (EPS) in S. epidermidis using precolumn derivation HPLC. Also cell surface hydrophobicities of S. epidermidis were assessed to explore action mechanisms. The qPCR was performed to demonstrate the genetic mechanisms of biofilm formation by S. epidermidis. Unlike other antibiotics, actinomycin D (1·5 μg ml-1 ) from Streptomyces luteus significantly inhibited biofilm formation by S. epidermidis. Additionally, it effectively inhibited S. epidermidis cells from adhering to glass slides. Actinomycin D downregulated ica locus and then the reduced polysaccharide intercellular adhesin production caused S. epidermidis cells to become less hydrophobic, thus supporting its anti-biofilm effect. CONCLUSION Streptomyces-derived actinomycin D is active in inhibiting the biofilm formation of S. epidermidis. SIGNIFICANCE AND IMPACT OF THE STUDY Actinomycin D can be used as a promising antibiofilm agent in inhibiting S. epidermidis biofilm formation. The study is also the first insight into how actinomycin D inhibited the biofilm formation of S. epidermidis. Actinomycin D could potentially be used to reduce the risk of biofilm-associated infections. Our study also suggests that the metabolites from Actinomycete strains keep further attention as potential antibiofilm agents against biofilm formation of S. epidermidis, even biofilm infections of the other bacteria.

Abstract
Objective: To investigate whether type 2 diabetes mellitus increases the risk of hepatitis B-related cirrhosis combined with type 2 diabetes mellitus for the occurrence of primary hepatocellular carcinoma, and to compare the effects of different nature of diabetes duration on the risk of different anti-diabetic drugs. Methods: A retrospective case-control study was conducted. (1) 325 cases with hepatitis B-related cirrhosis complicated with primary hepatocellular carcinoma were selected as the study group and 601 patients with hepatitis B cirrhosis as the control group. The relationship between diabetes mellitus and the risk of primary liver cancer was analyzed by multivariate logistic regression analysis. (2) Selected the study group and control group combined with type 2 diabetes mellitus, and used multivariate logistic regression analysis to study the relationship between diabetes-related factors and the risk of primary liver cancer. Results: The incidence of diabetes was 14.2% in the study group and 6.0% in the control group, and the difference was statistically significant between the two groups (P < 0.05). Multivariate logistic regression analysis showed that type 2 diabetes was one of the independent risk factors for primary hepatocellular carcinoma, which had increased the risk of primary hepatocellular carcinoma (adjusted odds ratio (AOR): 1.982, 95% CI: 1.224-3.210). Patients with diabetes > 10 years (adjusted ratio: AOR value 6.011, 95% CI: 1.659-21.777) were at significantly higher risk for primary hepatocellular carcinoma than that of patients with diabetes < 10 years. Metformin (adjusted odds ratio: AOR 0.188, 95% CI: 0.052-0.688) had reduced the risk, while insulin (adjusted odds ratio: AOR 6.682, 95% CI: 1.899-23.510) had increased the risk. Conclusion: Type 2 diabetes mellitus is one of the independent risk factors for primary HCC, which can increase the risk of hepatocellular carcinoma in hepatitis B cirrhosis in relation to the duration of diabetes mellitus. The risk of hepatocellular carcinoma is higher in patients with duration of diabetes > 10 years and metformin reduces the risk.

Abstract
Objective: To investigate the expression discordances of estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor2 (HER-2) and Ki-67 in primary and metastatic breast cancer specimens and explore the clinical significances. Methods: Biopsies of metastatic lesions were performed in 203 patients with breast cancer recurrence and metastasis indicated by physical examination and/or imaging examination. We confirmed pathological properties and assessed the expressions of ER, PR, HER-2 and Ki-67 in primary and metastatic lesions, their relationships with prognosis were also analyzed. Results: Biopsy failed in 3 patients, the pathology and immunohistochemitry results of metastatic lesions were not obtained. One person was diagnosed as tuberculosis and another was primary lung cancer. Among the 198 cases of primary and metastatic lesions, the discordance rates of ER, PR, HER-2 and Ki-67 were 27.3%, 34.3%, 11.8% and 15.1%, respectively.The expressions of ER, HER-2 and Ki-67 were not significantly different between the primary and metastatic lesions, however, the expressions of PR were more likely to turn negative in the metastases (P<0.001). The disease-free survival (DFS) of patients with ER, PR positive, HER-2 negative and low expression of Ki-67 in metastatic lesion was much longer (P<0.05). Conclusions: The expressions of ER, PR, HER-2 and Ki-67 in metastatic lesions are associated with the prognosis of breast cancer patients.Their expression discordances between primary and metastatic lesions can guide the treatment and evaluate the risks of recurrence and prognosis.

Abstract
Objective: To observe and analysis the changes of hemodynamic parameters and outcomes of pregnant women combined with congenital heart disease-pulmonary arterial hypertension (CHD-PAH). Methods: A prospective analysis of hemodynamic parameters of patients combined with CHD-PAH in Beijing Anzhen Hospital from January 2015 to December 2017 was carried out. Total 99 cases were divided into 4 groups based on systolic pulmonary arterial pressure (SPAP): mild group (SPAP 25-49 mmHg, 1 mmHg=0.133 kPa), moderate group (SPAP 50-79 mmHg), severe group (SPAP≥80 mmHg) and Eisenmenger syndrome group. Results: (1) SPAP of all groups increased during gestation, and the growth rates had no statistical differences (P>0.05). The SPAP in each group decreased after termination but was still higher than the early pregnancy's SPAP. (2) CHD-PAH patients in moderate [2 cm(2) (1-5 cm(2)), 1.0 cm (-2.0 - 2.0 cm)], severe [5 cm(2) (3-9 cm(2)), -3.5 cm (-6.0 - 1.0 cm)] or Eisenmenger syndrome [5 cm(2) (3-6 cm(2)), -1.0 cm (-5.5 - 2.0 cm)] group had larger right atrium area and smaller left ventricular end-diastolic diameter than patients in mild group [1 cm(2) (-1 - 4 cm(2)), 3.0 cm (1.0-6.0 cm)], the differences were statistically significant (all P<0.05). (3) Each group's SPAP/brachial arterial-systolic (BSAP) pressure continously increased during gestation. The SPAP/BSAP only decreased in patients in mild or moderate group after termination. However, the SPAP/BSAP kept rising in patients in severe group or Eisenmenger syndrome group. (4) CHD-PAH patients in severe or Eisenmenger syndrome group had worse cardiac function, in which the rates of Ⅲ-Ⅳ cardiac function were 61%(14/23) and 12/17, compared with patients in mild [8% (2/26)] and moderate [12%(4/33)] group, the differences were statistically significant (all P<0.05). (5) The rates of medicine treatment, cesarean section were higher, the weeks of gestational termination were earlier and the newborn's weights were lower in patients in severe or Eisenmenger syndrome group, the differences were statistically significant (all P<0.05). Conclusions: (1) SPAP keeps rising during gestation in all patients with CHD-PAH, and the SPAP decreases after termination but it's still higher than the early pregnancy's SPAP. This suggests that pregnancy would exacerbate these patients' heart problems, the risk should be fully considered before and during pregnancy. (2) Patients with severe CHD-PAH or combined with Eisenmenger syndrome have lager right atrium area, smaller left ventricular end-diastolic diameter, worse cardiac function, and bigger changes of hemodynamic, the incidence of adverse outcomes of mothers and children is also high, pregnancy should be avoided.

Abstract
Objective: To analyze the survival time of people living with HIV/AIDS and related influencing factors in Sichuan province during 1991-2017. Methods: A retrospective cohort study was conducted to analyze the data of 143 988 HIV/AIDS cases. The data were collected from Chinese HIV/AIDS Comprehensive Information Management System. Life table method was used to calculate the survival proportion of the cases, and Cox proportion hazard regression model was used to identify the factors related with survival time. Results: Among 143 988 HIV/AIDS cases a total of 30 420 cases died of AIDS related diseases (21.1%) and the average survival time was 11.51 years (95%CI: 11.39-11.64). Multivariate Cox regression analysis showed that the influencing factors for the survival of HIV/AIDS cases were gender (male vs. female, HR=1.35, 95%CI: 1.32-1.40), education level (primary school or below vs. junior middle school: HR=1.15, 95%CI: 1.12-1.18), ethnic group (Han vs. other ethnic groups, HR=1.46, 95%CI: 1.41-1.52), occupation (farmer vs. other occupations: HR=1.26, 95%CI: 1.22-1.29), age (≥55 years old vs. 15-24 years old: HR=3.18, 95%CI: 3.02- 3.36), disease phase (AIDS vs. HIV infection: HR=1.44, 95%CI: 1.39-1.48), antiretroviral therapy (ART) (receiving ART vs. receiving no ART: HR=0.20, 95%CI: 0.19-0.20), and CD(4)(+)T cell counts at diagnosis (>500 cells/μl vs.<200 cells/μl: HR=0.42, 95%CI: 0.40-0.45). Conclusions: The average survival time of HIV/AIDS cases was 11.51 years in Sichuan during 1991- 2017. The risk factors for the survival of the cases were male, education level of primary school or below, Han ethnic group, farmer, old age at diagnosis, disease phase, The protective factors for the survival of HIV/AIDS cases were receiving ART and higher CD(4)(+) T cell counts at diagnosis.

Abstract
Objective: To investigate the clinical effect and safety of long-acting pegylated interferon-α-2b (Peg-IFN-α-2b) (Y shape, 40 kD) injection (180 μg/week) in the treatment of HBeAg-positive chronic hepatitis B (CHB) patients, with standard-dose Peg-IFN-α-2a as positive control. Methods: This study was a multicenter, randomized, open-label, and positive-controlled phase III clinical trial. Eligible HBeAg-positive CHB patients were screened out and randomized to Peg-IFN-α-2b (Y shape, 40 kD) trial group and Peg-IFN-α-2a control group at a ratio of 2:1. The course of treatment was 48 weeks and the patients were followed up for 24 weeks after drug withdrawal. Plasma samples were collected at screening, baseline, and 12, 24, 36, 48, 60, and 72 weeks for centralized detection. COBAS® Ampliprep/COBAS® TaqMan® HBV Test was used to measure HBV DNA level by quantitative real-time PCR. Electrochemiluminescence immunoassay with Elecsys kit was used to measure HBV markers (HBsAg, anti-HBs, HBeAg, anti-HBe). Adverse events were recorded in detail. The primary outcome measure was HBeAg seroconversion rate after the 24-week follow-up, and non-inferiority was also tested. The difference in HBeAg seroconversion rate after treatment between the trial group and the control group and two-sided confidence interval (CI) were calculated, and non-inferiority was demonstrated if the lower limit of 95% CI was > -10%. The t-test, chi-square test, or rank sum test was used according to the types and features of data. Results: A total of 855 HBeAg-positive CHB patients were enrolled and 820 of them received treatment (538 in the trial group and 282 in the control group). The data of the full analysis set showed that HBeAg seroconversion rate at week 72 was 27.32% in the trial group and 22.70% in the control group with a rate difference of 4.63% (95% CI -1.54% to 10.80%, P = 0.1493). The data of the per-protocol set showed that HBeAg seroconversion rate at week 72 was 30.75% in the trial group and 27.14% in the control group with a rate difference of 3.61% (95% CI -3.87% to 11.09%, P = 0.3436). 95% CI met the non-inferiority criteria, and the trial group was non-inferior to the control group. The two groups had similar incidence rates of adverse events, serious adverse events, and common adverse events. Conclusion: In Peg-IFN-α regimen for HBeAg-positive CHB patients, the new drug Peg-IFN-α-2b (Y shape, 40 kD) has comparable effect and safety to the control drug Peg-IFN-α-2a.

[PMID: 30239873 DOI: 10.3382/ps/pey434] [Citation(s) in RCA: 36] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2018] [Accepted: 08/26/2018] [Indexed: 01/14/2023] Open
Abstract
This experiment was conducted to evaluate the effects of bile acids (BAs) on the growth performance and lipid metabolism of broilers fed with different energy level diets. 480 one-day-old Arbor Acres broilers (45.01 ± 0.26 g) were allotted to a 2 × 2 factorial design with 2 levels of energy (basal or high-energy level) and 2 levels of BAs (with or without BAs supplementation), resulting in 4 groups of 8 replicates; the experiment lasted 42 d. High-energy diets decreased the feed/gain ratio (F/G) from 1 to 21 d (P < 0.05), and increased the liver index and abdominal fat percentage at 42 d (P < 0.05). The serum total triglyceride (TG) and high-density lipoprotein cholesterol at 42 d were increased by high-energy diets (P < 0.05), while the hepatic lipoprotein lipase (LPL) activity at 21 and 42 d was decreased (P < 0.05). BAs supplementation increased the body weight at 21 d and decreased the F/G during entire period (P < 0.05), as well as improved the carcass quality reflected by decreased abdominal fat percentage at 42 d and increased breast muscle percentage at 21 and 42 d (P < 0.05). The serum TG at 21 and 42 d were decreased by BAs (P < 0.05), and the hepatic LPL activity at 42 d was increased (P < 0.05). In addition, high-energy diets increased the expression of sterol regulatory element binding transcription factor 1, acetyl-CoA carboxylase, and fatty acid synthase (P < 0.05), while BAs diets decreased these genes expression (P < 0.05). Moreover, BAs supplementation also increased the expression of carnitine palmitoyltransferase 1 (P < 0.05), which was increased in high-energy groups (P < 0.05). In conclusion, BAs supplementation could increase growth performance, elevate carcass quality, and improve lipid metabolism in broilers.

Abstract
Objective: Serum anti Müllerian hormone (AMH) was used to evaluate the effect of cyclophosphamide (CTX) on ovarian function in female patients with systemic lupus erythematosus (SLE). Methods: A total of 121 female patients who were 18-50 years old with normal menstruation were selected. Among them, 54 patients were treated with CTX as the study group and the remaining 67 cases as the control group. Before and after treatment for 6 months, the clinical characteristics, menstruation and AMH level of all patients were recorded and detected. At the same time, the method of using CTX and the cumulative measurement are recorded. Results: (1) Before treatment, there was no significant difference in AMH and mean age, duration of disease and SLEDAI score between the CTX treatment group and the control group. The renal injury in the CTX treatment group (44.4%) was higher than that of the control group (34.3%), and the difference was statistically significant (P<0.05). (2) After 6 months of treatment, the AMH of group CTX decreased from (2.39±1.58) μg/L to (1.56±1.42) μg/L, and the difference was statistically significant (P<0.01). But there was no significant change in the control group. In 54 cases of CTX treatment group, 23 cases (42.6%) had different degree of menstrual abnormalities, while 67 cases had only 8 cases (11.9%) in the control group. Moreover, the AMH level of 31 cases with abnormal menstruation was (0.95±0.59) μg/L, which was significantly lower than that of the other 90 normal cases (2.36±1.58) μg/L. (3) In 54 cases of CTX treatment group, the cumulative dose of CTX was less than 3 g in 14 cases, 33 cases of 3-6 g, 7 cases greater than 6 g. AMH was all were lower than those before treatment. But there was a statistical difference between the 3 g group and 3-6 g group before treatment, and there were statistical differences between the groups. Conclusion: CTX can damage ovarian function in women of childbearing age SLE. Low dose intravenous CTX may have less damage. Serum AMH can be used to monitor ovarian function in patients with SLE and to guide individualized treatment.

Abstract
OBJECTIVE To investigate the clinical characteristics of rheumatoid arthritis (RA) patients with malignant tumor. METHODS Retrospective summary was made of 1 562 in patients of RA from January 2011 to June 2017. In the study, 74 RA patients with malignant tumor were reviewed and analyzed, and the general conditions, tumor types, RA and tumor onset sequence, and the medication situation were analyzed. RESULTS The incidence of malignant tumor in the patients with rheumatoid arthritis in our center was 4.16%. The 74 patients were complicated with malignant tumor, of whom 53 were female, and 21 male. The age of RA at presentation was (52.6±17.8) years. The average disease duration of malignant tumor was (63.4 ± 12.7) years. The onset time of rheumatoid arthritis was earlier than that of malignant tumors in 51 cases (51/74), with an average of (17.2±14.2) years between 2 and 60 years. The incidence of malignant tumor was earlier than that of rheumatoid arthritis in 16 cases (16/74), with an average of (6.2±5.9) years between 1 and 21 years, of which 10 cases were sex hormone related tumors. Seven cases (7/74) were diagnosed with RA at the same time, and the time interval between the two diseases was within 1 year. All the patients were over 60 years old with digestive tract tumors. All the 7 patients showed polyarthritis, significantly increased erythrocyte sedimentation rate and C-reactive protein, including 4 rheumatoid factor positive cases and 2 anti-CCP antibody positive cases. The effect of non-steroidal anti-inflammatory drugs and traditional drugs to improve the condition of the disease was poor in the 7 patients, and the condition was relieved after using low-dose glucocorticoids. Gastrointestinal tumors, breast and reproductive system tumors were the most common, followed by respiratory, urological and blood system tumors. CONCLUSION The risk in patients of rheumatoid arthritis complicated with malignant tumor is higher than that of the general population. A variety of factors play an important role in cancer risk of RA, including disease activity, some estrogen metabolites, the use of drugs and so on. Therefore, all RA patients should be screened for malignant tumor during diagnosis, and malignant tumor surveillance is mandatory for all rheumatoid arthritis patients after diagnosis.

Abstract
Objective: To describe the clinicopathological features of synchronous mucinous metaplasia and neoplasia of the female genital tract (SMMN-FGT). Methods: The sample consisted of 7 cases of SMMN-FGT recorded from November 2014 to September 2017 at Obstetrics and Gynecology Hospital, Fudan University.PAP method was used in immunohistochemistry.Clinical histories were retrieved and pathological slides were reviewed. Results: The patients were 37 to 70 years old(mean 54 years old). All patients showed endometrial mucinous lesions associated with cervical lesions. Three cases were an admixture of minimal deviation adenocarcinoma(MDA) and gastrictype adenocarcinoma(GAS). Three cases were an admixture of lobular endocervical glandular hyperplasia (LEGH), atypical LEGH and focal gastrictype adenocarcinoma in situ, one of which had early invasive gastrictype adenocarcinoma.Endometrium showed a structure of LEGH in one patient with focal simple gastric mucinous metaplasia in her cervix. Gastric mucinous differentiation was found in unilateral fallopian tube in 6 patients. Ovarian mucinous lesions were found in 3 patients. p16 was negative staining in 6 cases and positive in 1 case. CK7 was diffusely positive in all lesions. CK20 and CDX2 were negative or only focally positive.The expression of MUC6 was strongly positive staining or focal staining. p53 in GAS and GAS in situ had mutant expression, but wild expression in MDA region. Patients were followed up for 2 to 34 months and no recurrence was found. Conclusions: SMMN-FGT is a series of rare mucinous lesions involving multiple areas of the female genital tract, including benign or malignant lesions with gastric differentiation. It is not related to infection with high-risk human papilloma virus. When cervical gastrictype lesions are found, SMMN-FGT should be considered and should be differentiated from metastatic mucinous adenocarcinoma.

Abstract
Objective: To investigate the reproductive health status of female workers engaged in administrative management, and to provide a reference for protecting the reproductive health of female workers. Methods: From April to November, 2016, a cross-sectional survey was performed for 2717 female workers aged 18-60 years and engaged in administrative management from 13 cities and provinces in China, and a questionnaire was used to investigate their general information, occupational hazards in workplace, and reproductive health status, and the reproductive health status of female workers was analyzed. Results: Of all 2 717 female workers, 1 170 had gynecological diseases or symptoms, resulting in an incidence rate of 43.06%, and among these workers, 11.15% had abnormal menstruation, 34.64% had infertility, and 38.76% had a history of abortion. There were significant differences in the rates of abnormal results of gynecological examination, abnormal menstruation, abortion, and infertility between the female workers in different age groups (P<0.01) . Unhealthy living habits and major events were risk factors for gynecological diseases, abnormal menstruation, and abortion (P<0.05) ; bad working status was a risk factor for gynecological diseases and abortion (P<0.05) ; exposure to harmful factors was a risk factor for gynecological diseases and abnormal menstruation (P<0.05) . Conclusion: Living habits, major events, working status, and occupational harmful factors have certain influence on reproductive health of female workers engaged in administrative management. Occupational health protection should be strengthened, working patterns should be improved, self-protection awareness should be raised, and health protection should be enhanced for women of childbearing age to protect and promote the reproductive health of female workers.

Abstract
The object of this study was to investigate the effect of curcumin on modulating the glutathione (GSH)-related antioxidant enzymes and antioxidant responses via NF-E2-related factor 2 (Nrf2) signaling pathway in heat-stressed broiler chickens. A total of 400 one-day-old male Arbor Acres broiler chicks was reared in an environmentally controlled room. At 21 d, broiler chicks were divided into 5 treatment groups and were fed one of 4 diets under 2 temperature conditions: 22°C + a basal diet (CON treatment); 34°C for 8 h (0900-1700) + a basal diet supplemented with 0, 50, 100, or 200 mg/kg curcumin (HS, CMN1, CMN2, and CMN3 treatments, respectively). The heat treatment lasted for 20 consecutive days. The results showed that heat stress significantly increased (P < 0.05) the weekly rectal temperature and average head and feet temperature. Compared to the HS treatment, feed conversion was significantly decreased (P < 0.05) in CMN1 and CMN2 treatments. CMN1 administration significantly improved (P < 0.05) the pH24 of muscle. The abnormal changes of serum malonaldehyde and corticosterone concentrations were prevented (P < 0.05) by curcumin. Mitochondrial GSH concentration in the liver was significantly increased (P < 0.05) in CMN1 and CMN2 treatments compared with the HS treatment. The CMN1, CMN2, and CMN3 supplementations significantly increased (P < 0.05) γ-GCL, GSH-Px, and GST activities. Curcumin significantly increased (P < 0.05) the expression of Nrf2, HO-1, and γ-GCLc in the liver as compared to the CON diet. The expression of Cu/ZnSOD and CAT were increased (P < 0.05) by feeding CMN2, respectively, as compared to the HS treatment. It was concluded that curcumin supplementation enhanced the resistance of broilers to heat stress, as evidenced by reversing the FC, increasing the GSH content and GSH-related enzyme activities, and inducing the expression of Nrf2 and Nrf2-mediated phase II detoxifying enzyme genes.

Abstract
Objective: To investigate the clinical and pathological characteristics and prognosis of ovarian clear cell borderline tumor. Methods: A total of 12 cases of ovarian clear cell borderline tumors recorded were collected from May 2011 to December 2017 at Obstetrics and Gynecology Hospital, Fudan University.Clinical histories were retrieved and pathological slides were reviewed. Results: The age of the patients ranged from 35 to 65 years with a mean age of 52 years. Seven cases were associated with cystic endometriosis of the ovary. All tumors consisted of irregular and crowded glands or cysts embedded in a fibromatous stroma. The cysts and glands were lined by mild to moderate atypical cells.CK7 and HNF-1β were expressed in all cases, and Naspin A was expressed in 11 cases. ARID1A expression was absent in 5 cases and p53 showed wild-type expression. None of the cases developed recurrence during follow-up ranging from 7 to 79 months. Conclusions: Ovarian clear cell borderline tumor may be associated with endometriosis and tumor suppressor gene ARIDA. The tumor has a good prognosis without recurrence and progression to carcinoma.

Abstract
The gastrointestinal tract is considered as one of the main target organs affected by heat stress. Phytogenic feed additives containing phenolics and flavonoids can improve the resistance of broilers to heat stress. This study was conducted to investigate the effects of dietary supplementation with enzymatically treated Artemisia annua (EA) on growth performance, intestinal morphology, digestive enzyme activities, immunity and antioxidant capacity of broilers challenged with heat stress. One hundred and forty-four 21-day-old male Arbor Acres broilers were randomly distributed into 3 treatments: 1) non-challenged control (CON); 2) heat-stress-challenged control (HS); and 3) heat-stress-challenged group + 1 g EA/kg diet (HS-EA). From 22 to 41 d, broilers in the CON group were housed at 22 ± 1°C, the HS and HS-EA groups, in which broilers were raised at 34 ± 1°C for 8 h (0900-1700 h) and the temperature for the rest time was the same as that of the CON group. The EA supplementation alleviated the compromised body weight gain and intestinal morphology impairment caused by heat stress challenge (P < 0.05). The EA attenuated heat-stress-induced decreased intestinal lipase, trypsin and total superoxide dismutase activities, and reduced intestinal secretory immunoglobulin A (SIgA) and IgG concentrations (P < 0.05). The EA inclusion prevented the elevation of intestinal malondialdehyde content and reduction of intestinal glutathione concentration induced by heat stress challenge (P < 0.05). The intestinal mRNA abundances of nuclear factor erythroid 2-related factor 2, heme oxygenase 1, glutathione peroxidase, gamma-glutamyl cysteine ligase larger catalytic subunit and gamma-glutamyl cysteine ligase smaller modulator subunit in heat-stressed broilers were increased in response to dietary EA treatment (P < 0.05). In conclusion, dietary supplementation of 1 g/kg EA could alleviate heat-stress-induced compromised growth performance and intestinal damage of broilers.

Abstract
Objective: To explore the correlation between the severity of gastroesophageal reflux cough and degree of gastroesophageal reflux. Methods: A cross-sectional investigation was carried out. Data of 174 cases of chronic cough were collected in Children's Hospital of Fuzhou from March 2009 to December 2016. The esophageal 24 hours pH value dynamic monitoring was used to detect gastric acid reflux index. Cases with abnomal results were divided into mild, moderate and severe groups according to severity of reflux and that of day and night cough symptoms, respectively. They were also divided into infant (1-3 years old), preschool (4-6 years old), and school age (>7 years old) groups according to age. Comparative analysis between groups by chi-square test and rank sum test were performed. Correlation analysis was used to analyze the correlation between cough severity and gastroesophageal reflux index. Results: A total of 174 patients with chronic cough, including 115 males and 59 females, aged from 1 to 15 years with an average age of (8.5±2.3) years, and (1.6±0.8) years of disease duration were enrolled. Among them, 129 cases (74.1%) were positive for esophageal reflux test and 45 cases (25.9%) with no obvious pathological gastroesophageal reflux. Patients with positive esophageal reflux test were divided into severe (n=37, 28.7%), moderate (n=23, 17.8%), and mild (n=69, 53.5%). There was no significant difference in the distribution of gastroesophageal reflux in each age group. (The proportions of mild, moderate and severe reflux in infants were 45.0% (9/20), 25.0% (5/20), and 30.0% (6/20), respectively. The proportions of mild, moderate and severe reflux in preschool children were 53.3% (32/60), 16.7% (10/60), 30.0% (18/60), respectively. The proportions of mild, moderate and severe reflux in school age children were 57.1% (28/49), 16.3% (8/49), 26.5% (13/49), respectively χ(2)=1.204, P=0.877). There was no correlation between age group and gastroesophageal reflux (r=-0.065, P=0.489).The severity of nighttime cough was positively correlated with percentages of distal esophagus pH≤4 in time, recumbent pH≤4 in time, and DeMeester score<14.72 (r=0.689, 0.621, and 0.707 respectively, all P<0.05). There was no statistically significant correlation between the severity of nighttime cough symptoms and percentage of standing pH≤4 in time (r=0.113, P>0.05). There were no statistically significant correlation between the severity of daytime cough and all gastroesophageal reflux markers (all P>0.05). Conclusion: The severity of nocturnal symptoms of gastroesophageal reflux cough is related to the degree of gastroesophageal reflux, to which clinical pediatricians should pay attention.
