Abstract
OBJECTIVES The aim of the study was to examine self-rated health (SRH) of Middle Eastern immigrants in the US compared with US-born non-Hispanic whites and to examine factors associated with fair/poor SRH among Middle Eastern immigrants in the US. STUDY DESIGN We used a cross-sectional design to analyze the National Health Interview Survey from 2001 to 2015. METHODS Secondary survey analysis procedures were conducted using the SAS program, with a total of 3,966 Middle Eastern and 731,285 US-born non-Hispanic whites. Descriptive statistics and regression analyses were used. RESULTS Middle Eastern immigrants had significantly higher rates of fair/poor SRH than US-born whites across the three survey waves. Reporting symptoms of serious psychological distress, older age (60+ years), current alcohol-drinking status, and having a family member with disability were the factors associated significantly with higher odds of reporting fair/poor SRH in Middle Eastern immigrants, whereas education was a protecting factor of fair/poor SRH. CONCLUSIONS This study indicates that Middle Eastern immigrants are one of the US immigrant populations that report poor health status, which reveals the need for health policy attention to reduce health disparities.

Abstract
Objective: To evaluate the role of endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) in lymph node staging and resectability assessment of patients with non-small cell lung cancer (NSCLC). Methods: The clinical data of 154 patients with NSCLC who underwent EBUS-TBNA from March 2015 to December 2018 were collected. All accessible mediastinal and hilar lymph nodes were systematically explored and punctured using EBUS-TBNA. EBUS-TBNA and CT were used for preoperative staging and resectability evaluation. Results: The sensitivity, specificity and accuracy of EBUS-TBNA were 94.2%, 100.0% and 96.0%, respectively, while those of CT were 89.9%, 31.8% and 72.0%, respectively. The differences were statistically significant (P<0.05). The sensitivity, specificity and accuracy of EBUS-TBNA in lymph nodes with short diameter less than 15 mm were 92.4%, 100.0% and 96.0%, respectively, while those of CT were 80.7%, 34.8% and 60.1%, respectively, with statistical differences (P<0.05). The staging of 62 patients was changed, 27 cases were up-regulated and 35 cases were down-regulated. Among them, 32 cases had been changed to resectable. The evaluating resectability of EBUS-TBNA showed excellent consistency with that of pathological results (Kappa=0.95). The sensitivity and specificity were 100.0% and 97.2%, respectively. Conclusion: EBUS-TBNA can systemically evaluate the metastatic status of NSCLC patients and improve the accuracy of preoperative lymph node staging and resectability assessment.

Abstract
Background Diabetic nephropathy (DN) is a common complication of diabetes mellitus (DM) that imposes an enormous burden on the healthcare system. Although some studies show that traditional Chinese medicine (TCM) treatments confer a protective effect on DN, the long-term impact remains unclear. This study aims to examine end-stage renal disease (ESRD) and mortality rates among TCM users with DN. Methods A total of 125,490 patients with incident DN patients from 2004 to 2006 were identified from the National Health Insurance Research Database in Taiwan and followed until 2012. The landmark method was applied to avoid immortal time bias, and propensity score matching was used to select 1:1 baseline characteristics-matched cohort. The Kaplan–Meier method and competing-risk analysis were used to assess mortality and ESRD rates separately. Results Among all eligible subjects, about 60% of patients were classified as TCM users (65,812 TCM users and 41,482 nonusers). After 1:1 matching, the outcomes of 68,882 patients were analyzed. For the ESRD rate, the 8-year cumulative incidence was 14.5% for TCM users [95% confidence interval (CI): 13.9–15.0] and 16.6% for nonusers (95% CI: 16.0–17.2). For the mortality rate, the 8-year cumulative incidence was 33.8% for TCM users (95% CI: 33.1–34.6) and 49.2% for nonusers (95% CI: 48.5–49.9). After adjusting for confounding covariates, the cause-specific hazard ratio of ESRD was 0.81 (95% CI: 0.78–0.84), and the hazard ratio of mortality for TCM users was 0.48 (95% CI: 0.47–0.50). The cumulative incidence of mortality increased rapidly among TCM users with ESRD (56.8, 95% CI: 54.6–59.1) when compared with TCM users without ESRD (30.1, 95% CI: 29.4–30.9). In addition, TCM users who used TCM longer or initiated TCM treatments after being diagnosed with DN were associated with a lower risk of mortality. These results were consistent across sensitivity tests with different definitions of TCM users and inverse probability weighting of subjects. Conclusions The lower ESRD and mortality rates among patients with incident DN correlates with the use of TCM treatments. Further studies about specific TCM modalities or medications for DN are still needed.

Abstract
Red yeast rice (RYR) has been used as an alternative treatment for hyperlipidemia. According to the previous studies, other compounds, besides monacolin K in RYR, may also reduce the serum lipid level. This study aims at examining the efficacy of monacolin K-rich and Gamma-Aminobutyric Acid (GABA)-rich RYR (Monascus pilosus) with regards to treating hyperlipidemia in a randomized control, double-blind clinical trial. In the research, we assigned 50 eligible subjects to monacolin K-rich RYR, GABA-rich RYR and placebo groups ( n=16 , 17, 17, respectively). The concentrations of TC, LDL-C, HDL, TG and blood biochemical data were evaluated at different phases: before applying (visit 1), after 1-month (visit 2), 2-month (visit 3), 3-month (visit 4) of providing the intervention and 1-month after ending the test food (visit 5) among three groups. During the 3-month intervention, the serum TC and LDL-C levels decreased significantly in the monacolin K group compared to the baseline and the other two groups. The Serum TG level declined steadily but was not statistically significant. Meanwhile, no marked differences in the serum HDL level were revealed among the three groups. Most safety assessment data had minor variation except two subjects (in monacolin K and GABA group separately) reported elevated liver enzymes. Monacolin K-rich RYR can reduce cholesterol as expected, while the GABA-rich RYR performed non-significant reduction on serum triglyceride. The research results demonstrate that using different concentrations and ratios between monacolin K and GABA could be beneficial for antihyperlipidemia.

Abstract
Objective: To observe the efficacy and safety between Pegfilgrastim (PEG-rhG-CSF) and Recombinant human granulocyte colony stimulating factor (rhG-CSF) in hematological malignancy after allogeneic hematopoietic stem cell transplantation (allo-HSCT) . Methods: 157 patients after allo-HSCT were enrolled in this study from June 2015 to November 2016. Two agents of G-CSF were used to stimulate hematopoietic recovery after transplantation. There were 65 cases in PEG-rhG-CSF and 92 cases in rhG-CSF groups. Patients in PEG-rhG-CSF group were given a single subcutaneous dose of 6 mg on the first day and +8 d, while cases in rhG-CSF group were given in dose of 5 μg·kg(-1)·d(-1) by subcutaneous injection from +1 d continuing to neutrophils more than 1.5×10(9)/L, and then the indicators and survival rates in two groups after transplantation were compared. Results: ①There were no significant differences of the neutrophil implantation time[13.5 (8-12) d vs 13 (9-24) d, P=0.393] and platelet implantation time [14 (9-160) d vs 14 (9-92) d, P=0.094] between PEG-rhG-CSF and rhG-CSF groups respectively. There were no significant differences in terms of neutropenia period (P=0.435) , number of cases who got fever during neutropenia (P=0.622) , and the median time of fever in neutropenia period (P=0.460) , respectively between the two groups. There were no significant differences of erythrocyte and platelet transfusions (P=0.074, P=0.059) within 1 month after transplantation. ②There were no significant differences with regard to the incidences of acute GVHD[23.1% (15/65) vs 34.8% (32/92) , P=0.115], chronic GVHD[20.0% (13/65) vs 32.6% (32/92) , P=0.081], Ⅱ-Ⅳdegree of acute GVHD[30.0% (13/65) vs 30.4% (30/92) , P=0.287] and extensive chronic GVHD[9.2% (6/65) vs 20.7% (19/92) , P=0.135] between PEG-rhG-CSF and rhG-CSF groups. ③There were no significant differences in terms of disease free survival (DFS) (62.5% vs 61.4%, P=0.478) and overall survival (OS) (67.4% vs 67.3%, P=0.718) between PEG-rhG-CSF and rhG-CSF groups. ④There was no significant difference of the non-relapse mortality (NRM) between PEG-rhG-CSF and rhG-CSF groups[20.5% (95%CI 11.4%-37.0%) vs 32.6% (95%CI 22.2%-47.9%) , P=0.141]. The relapse rate was not statistically significant[14.9% (95%CI 7.4%-29.8%) vs 10.0% (95%CI 5.0%-20.0%) , P=0.299]. Conclusion: Compared with rhG-CSF, PEG-rhG-CSF could reduce the times of injection. There were no differences in terms of hematopoietic recovery, the incidence of GVHD, relapse rate, DFS and OS rates after allo-HSCT between two groups.

Abstract
Objective: To examine the effects of ursodeoxycholic acid combined with Traditional Chinese Medicine on biochemical response in patients with primary biliary cholangitis. Methods: According to the method of receiving treatment, 197 patients with primary biliary cholangitis were divided into Traditional Chinese Medicine plus Western medicine group (93 cases, 47.2%) and Western medicine group (104 cases, 52.8%). From the baseline date, the combined group was treated with ursodeoxycholic acid plus traditional Chinese medicine decoction or Chinese patent medicine for at least one month and the Western medicine group simply took ursodeoxycholic acid . Additionally, Traditional Chinese medicine decoction prescriptions were mainly Xiaoyaosan and Yinchenhao. Chinese patent medicine were restricted to Biejia Ruangan tablets, Fuzheng Huayu capsules, Jiuweigantai capsules and Yinzhihuang capsules, which were used to treat liver fibrosis and cholestasis. The primary efficacy endpoint was defined as ALP level < 1.67 × ULN and ≥ 15% decrease in ALP with baseline level and TBIL≤ULN after 12 months of treatment. Results: The overall biochemical response rate of patients was 35.0% (69/197). The response rate of TCM+ Western medicine group was 43.0% (40/93), and that of Western medicine group was 27.9% (29/104). The difference between the two groups was statistically significant (χ(2) = 4.936, P < 0.05). Further analysis showed that the Chinese and Western medicine group was superior to the Western medicine group alone in reducing γ-glutamyltransferase (GGT) and TBiL [the median decline were GGT: 160.1 U/L and 111.3 U/L (Z = -2.474, P < 0.05), TBiL: 5.2 umol/l and 3.1 umol/l (Z = -2.125, P < 0.05)]. Conclusion: UDCA combined with TCM therapy can remarkably improve the biochemical response rate in patients with PBC and distinctly decrease the TBIL and GGT levels than UDCA monotherapy.

Abstract
BACKGROUND Locking plate fixation appears to be a standard treatment for proximal humeral fracture. Different locking plate designs might result in different radiographic and functional outcomes. The original version of the Proximal Humeral Internal Locking System (PHILOS; DePuy Synthes, Warsaw, IN, USA) occupied the largest volume of the humeral head by screw distribution, whereas the Zimmer Periarticular Locking Plate (ZPLP) system (Zimmer Biomet, Warsaw, IN, USA) occupied the smallest. METHODS We enrolled 50 patients undergoing ZPLP treatment and 50 undergoing PHILOS treatment. RESULTS The postoperative amount of impaction was significantly higher using the ZPLP System than using the PHILOS. Subgroup analysis showed that medial calcar support was another critical factor that affected surgical outcomes, especially when using the ZPLP System. CONCLUSION The amount of postoperative impaction was significantly higher when the ZPLP was used compared with the PHILOS locking plate. Medial calcar support is another critical factor that affects surgical outcomes. However, no significant differences in functional outcomes (Constant-Murley score) between the ZPLP System and the PHILOS were noted at the 12-month follow-up.

Abstract
Chronic kidney disease (CKD) has a high incidence and prevalence worldwide, and chronic glomerulonephritis (CGN) is one of the main causes of CKD. Therefore, it is important to diagnose and treat CGN early. The purpose of this study is to analyze the prescription patterns and frequencies of Chinese herbal products (CHPs) for CGN by using a hospital-based database from the Chang Gung Memorial Hospital (CGMH), a large, tertiary hospital system in Taiwan, and to evaluate the safety and possible efficacy of CHPs by blood test. The International Classification of Disease Ninth Revision (ICD-9) code 582 was used to identify patients with CGN. From 2004 to 2015, a total of 54726 CHP prescriptions for CGN were provided. Association rule mining was used to analyze the prevalent of CHP combination patterns in treating CGN. Jia-Wei-Xiao-Yao-San (JWXYS) and Gorgon (Euryale feroxSalisb.) were the most frequently prescribed herbal formula (HF) and single herb (SH), respectively. The most frequently prescribed combination of CHPs was that of JWXYS with Bu-Yang-Huan-Wu-Tang (BYHWT) in CGMH. In statistical, the level of eGFR in Stage 3a and 3b group was increasing after treatment in 6 and 12 months and might not cause the renal function to worsen within 12-month treatments. To the best of our knowledge, this is the first pharmacoepidemiological study to review CHP treatments for CGN. However, additional studies and clinical trials are needed to provide data on the safety and efficacy of these CHPs.

Abstract
Objective: To investigate the clinical features of adult-onset chronic active Epstein-Barr virus infection (CAEBV). Methods: A total of 21 adult patients with CAEBV who were admitted to the department of General Internal Medicine at Peking Union Medical College Hospital from January 2006 to January 2016 were retrospectively analyzed. Demographic data, disease duration, clinical manifestations, laboratory findings, treatments and prognosis were reviewed. Results: Eighteen females and 3 males were enrolled with a mean age of 39 years. The most common clinical manifestations included fever in 20 patients, splenomegaly in 20 patients, lymphadenopathy in 18 patients, and hepatomegaly in 10 patients, followed by laryngopharyngeal disorders in 6 patients, pleural effusion and peritoneal effusion each in 5 patients, rash in 4 patients, interstitial lung disease in 3 patients, gastrointestinal hemorrhage in 2 patients, and peripheral neuropathy and pulmonary hypertension each in 1 patient. Six patients were complicated with hemophagocytic lymphohis-tioncytosis(HLH) that developed 5-17 (mean: 9) months following CAEBV onset, all of whom experienced hyperpyrexia, pancytopenia, lymphadenopathy, splenomegaly, and liver dysfunction, 3 with hepatomegaly. Nineteen of the 21 patients had received steroid therapy including 10 combined with immunosuppressive agents, 11 with antiviral therapy, and 8 with intravenous immunoglobulin. Thirteen patients died, including 10 of multiple organ failure, (including 6 of HLH) 2 of severe pulmonary infection, and 1 of lymphoma. Six patients remained on follow-up, yet 2 were missing. Conclusions: CAEBV is expected with severe condition and poor prognosis, which is likely to be complicated with HLH. Clinical physicians should pay attention to adult patients with fever, hepatosplenomegaly and lymphadenopathy, which suggests possible CAEBV.

Abstract
To understand the erosion effect of neutral particles on the first wall, a low energy neutral particle analyzer (LENPA), based on the time-of-flight method, has been developed for the Experimental Advanced Superconducting Tokamak (EAST). The LENPA to be installed in the EAST mid-plane mainly consists of a chopper sub-system, a 3 m long flight tube, two sets of detector assemblies, and data acquisition and processing, vacuum, power supply, and control sub-systems. The neutral outflux is gated in bunches of 1 μs time scale by a slotted rotating disc which is driven by a vacuum compatible motor modified from a turbomolecular pump. A He-Ne laser beam is projected through the disc slit to record the instants of chopper slits opening with an avalanche photodiode module. An on-axis electron multiplier detects chopped neutrals, and a central perforated Cu-Be plate is employed to channel the emitted secondary electrons into an off-axis electron multiplier. The radiation peaks of on-axis electron multiplier caused by UV photons projected through the central hole of the Cu-Be plate provide an alternative way to record the chopper slits' opening time. With an additional 4 TB fast memory card, 1 GS/s sampling rate has been realized by using a GaGe acquisition card continuously. The LENPA data from the EAST together with neutral particle material erosion experiments will be used to benchmark the simulation results for better predictions on future fusion reactors, such as ITER and China Fusion Engineering Test Reactor (CFETR).

Objective: To investigate the effects of Toll-like receptor 4 (TLR4)-phosphatidylinositol 3-kinase (PI3K) -Ras-related C3 botulinum toxin 1 (Rac1) signaling pathway on macrophage cytoskeleton rearrangement and phagocytosis. Methods: Mouse macrophage cell line RAW264.7 was divided into blank group, negative control group and TLR4-RNA interference (RNAi) group. The lentivirus carrying TLR4 short hairpin RNA (shRNA) and nonsense control sequence were respectively transfected into TLR4-RNAi group and negative control group. The cells in blank group were not transfected. The silencing efficiency of TLR4 was detected by Western blot. Real-time fluorescence quantitative PCR was used to detect the expression of PI3K and Rac1 mRNA in each group. The expressions of PI3K, p-Rac1 and Rac1 protein were detected by Western blot. Cytoskeleton was observed by laser scanning confocal microscopy. Mean fluorescence intensity (MFI) and the percentage of cells phagocytosing flurescein inothiocyanate-labeled Eseherichina coli (FITC-E.coli) (Phagocytosed cell %) were detected by flow cytometry. Results: The RAW264.7 cells can be successfully transfected by TLR4-shRNA lentivirus, and the transfection efficiency ranged from 80% to 90%. The silencing efficiency of TLR4 gene was (63±4)%. After silencing the TLR4 gene, the relative expression of TLR4 mRNA and protein (0.20±0.03, 0.37±0.04), PI3K mRNA and protein (0.64±0.06, 0.75±0.06), Rac1 mRNA, protein and p-Rac1 protein (0.75±0.04, 0.76±0.01, 0.74±0.05) in TLR4-RNAi group were significantly lower than those in negative control group and blank group (all P<0.01). The change of cytoskeleton: after silencing the TLR4 gene, the celluar pseudopods were short and stiff, with the impaired capacity of phagocytosing FITC-E.coli. Cells in blank group and negative control group extended good pseudopodia, and the capacity of phagocytosing FITC-E.coli was normal. The MFI and Phagocytosed cells % of TLR4-RNAi group[(7 453±564), (70.20±2.27)%]were significantly lower than those in the blank group and the negative control group (all P<0.01). Positive correlations were existed between mRNA, protein expression of TLR4, PI3K, Rac1 and MFI, Phagocytosed cells% (all P<0.05) in all groups. Conclusion: TLR4-PI3K-Rac1 pathway involves in the cytoskeleton rearrangement and impairs the phagocytosis of macrophages.

Abstract
RATIONALE Although pseudoaneurysm (PA) formation following primary and revision total hip arthroplasty (THA) is rare, PA rupture may lead to severe complications that can result in a threat to life and limb. PATIENT CONCERNS A 65-year-old man presented with acute hemorrhagic discharge for one day from the chronic hip sinus secondary to revision THA that had been performed 6 years ago, for which he had received multiple courses of debridement, antibiotics, and implant retention procedures owing to periprosthetic joint infection (PJI). DIAGNOSES Radiographs showed septic loosening of both the femoral and acetabular components, with medial migration of the component beyond Kohler's line. Contrast-enhanced computed tomography angiogram of the abdomen and pelvis of the patient demonstrated a large PA of the right external iliac artery (EIA), measuring 6.1 cm × 7.7 cm in diameter and 9.1 cm in length. INTERVENTIONS A ball-shaped antibiotic-loaded cement spacer (ALCS) was used to tamponade a bleeding PA, treat the coexisting PJI, and thus facilitate endovascular stent-graft repair (ESGR) later on. OUTCOMES The ESGR resulted in complete exclusion of the PA and successfully controlled the bleeding. The patient underwent a successful revision THA 6 months after stent insertion. Neither stent-graft infection nor recurrent PJI were detected at 18 months. LESSONS Given the potential of a PA for causing significant morbidity and mortality, the surgeon should have an elevated index of suspicion in the presence of intrapelvic migration of the acetabular component. While facing a PA rupture with/without hemorrhagic shock in patients with coexisting hip PJI, ALCS ball implantation and subsequent ESGR might be an effective method to save the patient's life and limb.

Abstract
Measurement of laterality of motor cortical activations may provide valuable information about lower limb control in children with unilateral cerebral palsy (UCP). Evidence from upper limb research suggests that increased contralateral activity may accompany functional gains. However, lower limb areas of activation and associated changes have been underexplored due to challenges with imaging motor cortical leg representations. In this study, methods for a task-based functional magnetic resonance imaging (fMRI) ankle dorsiflexion paradigm were refined with three pilot groups of participants: (i) adults (n = 5); (ii) typically developing (TD) children (n = 5) and; (iii) children with UCP (n = 4). Parameters of experimental design, task resistance, reproducibility, and pre-scan procedures were tested/refined using a staged development approach with additions or changes introduced if image quality did not meet pre-defined standards. When image quality was acceptable for two consecutive participants, the next participant group was recruited to test/refine the next parameter. The final paradigm involved an event-related design of a single dorsiflexion movement against individualized resistance, with two runs per leg. It included a pre-scan session to increase child comfort and determine task resistance. This paradigm produced valid data for laterality index (LI) calculations to determine the ratio of activity in each hemisphere. Ventricle and lesion masks were used in non-linear image registration, and individual thresholds were used for extent-based LI calculations. LI of dominant ankle movements were contralateral (LI ≥ +0.2) for TD children (mean LI = +0.89, std = 0.27) and children with UCP (mean LI = +0.86, std = 0.26). For the affected ankle of children with UCP, LI values indicated ipsilateral and/or contralateral activation (mean LI = +0.02, std = 0.71, range -0.92 to +1.00). This fMRI paradigm will support investigations of cortical activation and mechanisms of skill improvement following lower limb interventions.

Abstract
A case of intraorbital hematoma after surgery of recurrent nasal polyps in August 2016 was reviewed. The patient underwent emergent orbital decompression after intraorbital hematoma, and followed up for half a year. The eyeball blood stasis of the case had gradually vanished. Ocular movement and vision of the left are still normal now. Orbital decompression is both necessary and effective for intraorbital hematoma after surgery of nasal endoscope.

Abstract
Objective: To investigate the safety and efficacy of radiofrequency ablation (RFA) with percutaneous iohexol-ethanol injection (PIEI), compared with RFA plus transcatheter arterial chemoembolization (TACE) for patients with primary liver cancer(PLC)in high-risk locations. Methods: From January 2012 to December 2014, 54 patients with PLC in high-risk locations were enrolled. They were divided into Group A (RFA combined with PIEI) and Group B (RFA plus TACE). The efficacy and adverse events were assessed. Results: 54 patients had 74 lesions in high-risk locations. There were 26 cases with 40 lesions in Group A, and 28 cases with 34 lesions in Group B. The complete ablation rate of Group A was significantly higher than that of Group B (92.5% vs 70.6%, P=0.014). The two-year local tumor progressionrateand two-year overall survival rate were similar between these two groups (Group A 20.0% vs Group B 38.2%, P=0.083; 90.3% vs 84.3%, P=0.523). Furthermore, the surgery-related severe adverse events of Group A (7.1%, one case of liver abscess and one case ofhematobilia) were more common than that of Group B (0%, P=0.491). No significant differences were found in common adverse events including fever, pain, elevation of aminotransferase and bilirubin. Conclusions: Compared with RFA plus TACE, RFA plus PIEI resulted inbetter complete ablation rate in patients with primary liver cancer in high risk locations. Prospective, randomized, controlled trials are warranted for further evaluation.

Abstract
BACKGROUND The objective of this study was to investigate the contributions of mental health status and attitudes towards suicide on suicidal ideation in a sample of 6568 Chinese children and adolescents in China. Attitudes towards suicide were investigated as a possible moderator and mediator of the influence of mental health status on suicidal ideation. METHODS Descriptive statistical analyses, Pearson correlation analyses and hierarchical regression analyses were adopted as methods of data analyses. RESULTS Approximately 35.38% of children and adolescents in our study reported having suicidal ideation. Mental health status and attitudes towards suicide both had an independent effect on the severity of suicidal ideation. Results indicated that mental health status was positively associated with suicidal ideation, while attitudes towards suicide were negatively associated with suicidal ideation. Moderation analysis showed that the impact of mental health status on suicidal ideation was significantly greater among children and adolescents who reported favourable attitudes towards suicide. Attitudes towards suicide partially mediated the link between mental health status and the severity of suicidal ideation. Specifically, students who experienced poorer mental health status might be more likely to report significantly more favourable attitudes towards suicide, which in turn promote greater suicidal ideation. CONCLUSIONS These results have implications for the prevention of youth suicide, suggesting that mental health status and attitudes towards suicide could be important targets for prevention and intervention for children and adolescents at risk of suicidal ideation.

Abstract
In this study, we investigated thermotolerance, several physiological responses and damage to reproductive cells in chlorpyrifos-resistant (Rc) and -susceptible (Sm) strains of the diamondback moth, Plutella xylostella subjected to heat stress. The chlorpyrifos resistance of these strains was mediated by a modified acetylcholinesterase encoded by an allele, ace1R, of the ace1 gene. Adults of the Rc strain were less heat resistant than those of the Sm strain; they also had lower levels of enzymatic activity against oxidative damage, higher reactive oxygen species contents, weaker upregulation of two heat shock protein (hsp) genes (hsp69s and hsp20), and stronger upregulation of two apoptotic genes (caspase-7 and -9). The damage to sperm and ovary cells was greater in Rc adults than in Sm adults and was temperature sensitive. The lower fitness of the resistant strain, compared with the susceptible strain, is probably due to higher levels of oxidative stress and apoptosis, which also have deleterious effects on several life history traits. The greater injury observed in conditions of heat stress may be due to both the stronger upregulation of caspase genes and weaker upregulation of hsp genes in resistant than in susceptible individuals.

Abstract
The accumulation of H at the small-angle tilt grain boundary (GB) in the W(001) surface is investigated, on the basis of the first-principles calculations. By exploring the solution and diffusion behaviors of H at the GB, we find that the small-angle GB can capture the H atoms nearby, serving as a nucleation site of H bubbles. With the increasing number of trapped H atoms, the GB expands gradually, and the GBs can be unripped with an areal density of H up to 5.0 × 1015 H atoms per cm2, leading to the formation of H bubbles. Moreover, H2 molecules are observed, when the areal density of H atoms in GB is over 6.6 × 1015 atoms per cm2. According to our calculations, we propose a possible formation mechanism of H bubbles observed in the experiment, which is valuable for improving the service performance of W as a plasma-facing material in nuclear fusion reactors.
