Abstract
OBJECTIVE The purpose of this study was to investigate the efficacy and safety of lenvatinib in various types of solid tumors. METHOD By searching PubMed, Web of Science, Cochrane, CNKI, Wanfang and other databases, all the literatures about the comparison of clinical efficacy of lenvatinib in the treatment of various solid tumors. According to the criteria of inclusion and exclusion of literature, two participants screened the literature, collated the data and evaluated the literature. RevMan 5.4 software was used for meta-analysis of the included literatures. RESULTS A total of 12 studies were included, including 5213 patients. Meta-analysis showed that, in terms of efficacy, the risk (HR) of prolonging PFS in the treatment of various solid tumors in the lenvatinib group was 1.91 times that in the control group (HR = 1.91, 95% CI: 1.58-2.31, p < 0.00001), and the risk (HR) of prolonging OS was 1.27 times that in the single targeted drug group (HR = 1.27, 95% CI: 1.15-1.40, p < 0.00001). In terms of safety, the risk of adverse events in the treatment of various solid tumors in the lenvatinib group was higher than that in the control group, especially in Endocrine Toxicities, Renal/Urinary Toxicities, Vascular Toxicities, Musculoskeletal/a Connective Tissue Toxicities and Metabolism/Nutrition Toxicities. CONCLUSIONS Lenvatinib in various solid tumors can prolong OS and disease PFS of patients, improve the clinical benefit rate and improve the quality of life of patients. At the same time, there is a certain incidence of adverse events, and symptomatic intervention should be given in clinical medication.

Abstract
Objective: Clinical studies have shown that trastuzumab combined with pertuzumab (dual-targeted drug therapy) can significantly improve the treatment status and prognosis of HER-2 positive breast cancer patients through double targeting of HER-2. This study systematically evaluated the efficacy and safety of trastuzumab combined with pertuzumab in the treatment of HER-2 positive breast cancer.Method: We search relevant databases and collect RCTs on the treatment of HER-2 positive breast cancer with dual-targeted treatment. Meta-analysis was performed using Revman5.4 software.Results: A total of 10 studies for 8553 patients were included. Meta-analysis showed that, in terms of efficacy, overall survival (OS) (HR = 1.40, 95%CI = 1.29-1.53, p < 0.00001) and progression-free survival (PFS) (HR = 1.36, 95%CI = 1.28-1.46, p < 0.00001) in dual-targeted drug therapy were better than which in the single-targeted drug group. In terms of safety, the highest incidence (Relative risk, RR) of Adverse reactions was Infections and infestations (RR = 1.48, 95%CI = 1.24-1.77, p < 0.0001) follow by Nervous system disorders (RR = 1.29, 95%CI = 1.12-1.50, p = 0.0006), Gastrointestinal disorders (RR = 1.25, 95%CI = 1.18-1.32, p < 0.0001), Respiratory, thoracic, and mediastinal disorders (RR = 1.21, 95%CI = 1.01-1.46, p = 0.04), Skin and subcutaneous tissue disorders (RR = 1.14, 95%CI = 1.06-1.22, p = 0.0002) and General disorders (RR = 1.14, 95%CI = 1.04-1.25, p = 0.004) in dual-targeted drug therapy group. The incidence of Blood system disorder (RR = 0.94, 95%CI = 0.84-1.06, p = 0.32) and Liver dysfunction (RR = 0.80, 95%CI = 0.66-0.98, p = 0.03) was lower than that of the single targeted drug group.Conclusion: Dual-targeted treatment for HER-2-positive breast cancer can prolong the OS, PFS and improve the quality of patients' life. Meanwhile, it also brings a higher medication risk, which requires a rational selection of drug symptomatic interventions.

Abstract
Drilling fluid waste is produced by oil and gas industry operations and can potentially cause serious environmental pollution and energy consumption if not properly treated. Currently, there are several treatment methods available for drilling fluid waste such as bioremediation, thermal treatment, solidification/stabilization treatment, electrochemical remediation, physiochemical treatment, and supercritical fluid treatment. However, selecting an adequate method to treat drilling fluid waste is a critical consideration. The objective of this work is to analyze the problem of drilling fluid waste pollution and treatment methods, establish a drilling fluid waste treatment decision index system that takes into account various factors, and apply the intuitionistic fuzzy-based entropy weight method (EWM)-technique for order of preference by similarity to ideal solution (TOPSIS) method to make a multi-attribute group decision on drilling fluid waste treatment methods. The method is then applied to the WBQ004-1-H1 drilling project as an example for comprehensive analysis. The final decision results show that A3 (0.566) > A1 (0.537) > A6 (0.526) > A5 (0.485) > A4 (0.478) > A2 (0.447), so the solidification/stabilization treatment is the most suitable method for this project, providing new insights into selecting drilling fluid waste treatment methods in actual projects.

Abstract
Cancer is a disease with high morbidity and mortality in the world. In the past, the main treatment methods for cancer patients were surgery, radiotherapy and chemotherapy. However, with early treatment, the recurrence rate of cancer is higher, and the drug resistance of cancer cells is faster. In recent years, with the discovery of immune escape mechanism of cancer cells, Immunotherapy, especially Immune Checkpoint Inhibitors (ICIs), has made a breakthrough in the treatment of solid tumors, significantly prolonging the overall survival time and disease-free progression in some solid tumors, and its clinical benefits are more prominent than those of traditional anti-tumor drugs, which has become the hope of cancer patients after the failure of multi-line therapy. More and more studies have shown that there is a correlation between cancer driving genes and the clinical benefits of ICIs treatment, and the therapeutic effects and adverse reactions of ICIs can be predicted by the status of driving genes. Therefore, screening potential biomarkers of people who may benefit from immunotherapy in order to maximize the therapeutic benefits is a top priority. This review systematically summarizes the cancer driving genes that may affect the clinical benefits of immune checkpoint inhibitors, and provides accurate scientific basis for clinical practice.

Abstract
OBJECTIVES This study aimed to investigate associations of resting heart rate (RHR) and blood pressure (BP) with all-cause and cardiovascular disease (CVD) mortality. STUDY DESIGN A retrospective cohort study. METHODS A total of 67,028 Chinese participants aged ≥60 years were included in the analysis. RHR, systolic blood pressure (SBP), and diastolic blood pressure (DBP) were evaluated according to quartiles ([41-69, 70-74, 75-79, 80-127 beats/min], [80-119, 120-129, 130-139, 140-238 mm Hg], and [40-70, 71-79, 80-84, 85-133 mm Hg]). Cox proportional hazard models were used to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs) of all-cause and CVD mortality with RHR, SBP, and DBP. Restricted cubic splines were used to evaluate the dose-response association. RESULTS During the 361,975 person-year follow-up, 9326 deaths were recorded, of which 5039 deaths were due to CVD. The risk of all-cause mortality was increased by 25% with the quartiles four vs quartile one of RHR (HR [95% CI]:1.25 [1.17-1.33]), and CVD mortality was increased by 32% (HR [95% CI]: 1.32 [1.22-1.44]). Similar results were observed when comparing the quartiles four vs quartile one of SBP with the risk of all-cause and CVD mortality (HRs [95% CIs]: 1.14 [1.07, 1.22] and 1.23 [1.12. 1.34]) and DBP with the risk of all-cause and CVD mortality (HRs [95% CIs]: 1.17 [1.11. 1.24] and 1.36 [1.26. 1.47]). We found linear associations of RHR, SBP, and DBP with all-cause and CVD mortality (Pnon-linearity >0.05), except for the approximately J-shaped association between DBP and all-cause mortality (Pnon-linearity = 0.008). There was a significant interaction of RHR and SBP with all-cause and CVD mortality (Pinteraction <0.05). CONCLUSIONS RHR and BP increased the risk of all-cause and CVD mortality, especially fast RHR combined with high SBP.

Abstract
Background: Immune checkpoint inhibitors (ICIs) have become an effective treatment option for cancer. KRAS, EGFR and TP53 are common mutated oncogenes in cancer whose single gene status may predict the therapeutic effect of clinical ICIs. In this efficacy evaluation, we aimed to clarify whether the single gene mutation status of KRAS, EGFR or TP53 affects the survival benefits of ICIs in cancer patients. Methods: We used PubMed, Cochrane Library, web of science, and clinical trials Gov database to retrieve qualified documents, the time was up to January 2022. Hazard ratios (HRS) and 95% confidence intervals (CIs) were used to determine the single gene mutation status and no progression of KRAS, EGFR or TP53. Results: A total of 19 studies included 7029 cancer patients treated with ICIs. The results showed that KRAS, EGFR or TP53 single gene mutation could significantly improve PFS and OS in patients receiving ICIs, but the degree of improvement was different. The risk of prolongation of PFS (HR = 1.48, 95% CI = 1.19-1.85, p = 0.0004) and OS (HR = 1.68, 95% CI = 1.36-2.07, p < 0.00001) caused by TP53 single gene mutation was relatively high, the risk ratio of prolongation of PFS (HR = 1.38, 95% CI = 1.21-1.57, p < 0.00001) and OS (HR = 1.56, 95% CI = 1.20-2.04, p = 0.001) caused by EGFR single gene mutation was the second, the risk ratio of prolongation of PFS (HR = 1.33, 95% CI = 1.12-1.57, p = 0.001) and OS (HR = 1.39, 95% CI = 1.18-1.63, p < 0.00001) caused by KRAS single gene mutation was relatively low, and the results were significantly different. Conclusion: In cancer patients, KRAS, EGFR or TP53 single gene status is correlated with the benefits of immunotherapy PFS and OS, which suggests that gene sequencing should be carried out in time in the process of clinical treatment to determine the gene mutation of patients and better predict the clinical treatment effect of ICIs.

Abstract
Objective Immune checkpoint inhibitors (ICIs) have changed the outcomes of a variety of cancers in an unprecedented manner. Gut microbiome plays a crucial regulatory role in the antineoplastic therapy of ICIs, which can be influenced by antibiotic (ABX) administration. In this efficacy evaluation, we aimed to clarify the correlations of ABX administration with the survival of cancer patients receiving ICIs treatment. Method The eligible literatures were searched using PubMed, Cochrane Library, Web of Science, and Clinical trials.gov databases before Nov 2021. The correlations of ABX administration with progression-free survival (PFS) and overall survival (OS) were determined using Hazard ratios (HRs) coupled with 95% confidence intervals (CIs). Results A total of 12 studies enrolling 6010 cancer patients receiving ICIs treatment were included in this efficacy evaluation. ABX administration was significantly correlated worse PFS (HR=1.60, 95%CI=1.33-1.92, P<0.00001) and OS (HR=1.46, 95%CI=1.32-1.61, P<0.00001). Similar results were found in the subgroup analysis of non-small cell lung cancer (NSCLC), renal cell carcinoma (RCC) and melanoma. Conclusions ABX use during ICIs treatment of cancer may significantly shorten PFS and OS. ABX should be used cautiously in cancer patients receiving ICIs. However, further validations are still essential due to existing publication bias.

An average daily moderate-to-vigorous physical activity (MVPA) of at least 60 minutes was recommended by the Canadian Guidelines for children. Because of lockdown restrictions during the COVID-19 pandemic, maintaining physical activity levels (PAL) has been a challenge for youth.
Aims
The primary aim of this study was to compare MVPA levels in children with inflammatory bowel diseases (IBD) before and after this period. The secondary aims were to assess clinical factors that might influence any changes in MVPA patterns.
Methods
Patients with IBD, age ≥5 years, were enrolled in a prospective study on PAL starting June 2018 (self-reported questionnaires during outpatient visits). They were then surveyed online at the end of the second lockdown in July-August 2021. PAL were assessed with the Canadian Health Measure Survey Children-Physical Activity Questionnaire. The responses were converted into metabolic equivalents of tasks by using validated tables. Influence of clinical factors of IBD on changes in MVPA was assessed. A multivariate logistic regression was performed to investigate the association between several risk factors and PAL.
Results
We included 72 patients (38 males; mean (SD) age 17.0 (2.89) years, 48 (66.7%) diagnosed with Crohn’s disease, 19 (26.4%) with ulcerative colitis, and 5 (6.9%) with indeterminate colitis). At last follow-up, 90.3% were in clinical remission according to validated disease activity score. During summer 2021, 16.7% of patients reached the Canadian PAL target, compared to 38.9% before the pandemic. The median daily duration of MVPA in summer 2021 decreased from 37 (Interquartile range (IQR) = 3–82) to 21 (IQR=3–40) minutes. The proportion of sedentary patients increased by 1.4% (37.5% to 38.9%). The proportion of extremely active patients decreased by 16.7% (27.8% to 11.1%), while moderately active patients increased by 20.9% (8.3% to 29.2%). Age, gender, disease type and activity were not significantly associated with the PAL at baseline or at follow-up.
Conclusions
This study found a significant decrease in PAL and time spent doing MVPA in children with IBD in Quebec following the COVID-19 pandemic lockdown. While the recommended target was far from being met before the pandemic, the gap has widened further during the pandemic. We found no clinical factors associated with the PAL. The impact of low PAL on well-being, weight, disease activity and quality of life will be assessed during the follow-up of this cohort.

Abstract
Petroleum sludge is produced during oilfield development and production and can negatively impact the production area and surrounding environment. With increasing attention to the environmental protection of oilfields, finding an energy-efficient, environmentally sound, cost-effective and socially acceptable sludge treatment method is crucial to the sustainable development of oil companies. However, there are several problems in the selection process: ① there is no effective index system for the evaluation of treatment technologies; ② there is data uncertainty and loss of information; ③ experts in the field often make one-sided decisions; and ④ the common decision models fail to balance the general effect and local dominance of a treatment technology. This study is innovative in the following aspects: ① a decision index system of petroleum sludge treatment technology is established; ② the interval-valued Pythagorean fuzzy set effectively managed data uncertainty and loss of information; ③ the redundancy-based expert weighting method is used to avoid one-sided decisions; and ④ using the basic ideas of the VIKOR model to balance the general effect and local dominance of a technology. Example verification proved the effectiveness of this method and a sensitivity analysis showed the results were reliable. Finally, this study compared the results obtained by three other similar methods, and comparative analysis demonstrated that this approach effectively evaluated and selected petroleum sludge treatment technologies. This study improves the rationality of petroleum sludge treatment technology selection and provides a necessary reference for the selection of treatment technology for other petroleum pollutants.

Abstract
BACKGROUND Dupilumab is an antibody against interleukin 4 receptor α, used in treating atopic dermatitis (AD). OBJECTIVES To evaluate the efficacy and safety of dupilumab in adult Chinese patients with moderate-to-severe AD. METHODS In this randomized, double-blind, placebo-controlled, parallel-group, phase III study, conducted between December 2018 and February 2020, patients with AD received dupilumab (300mg) or placebo once every 2 weeks for 16 weeks, and were followed up for 12 weeks. The primary efficacy endpoint was the proportion of patients with both Investigator's Global Assessment (IGA) score of 0-1 and a reduction from baseline of ≥2 points at week 16. RESULTS Overall, 165 patients (mean age: 30.6 years; 71.5% male) were randomized: 82 to dupilumab and 83 to placebo. At week 16, 26.8% of patients in the dupilumab group and 4.8% of patients in the placebo group achieved the primary endpoint (difference, 22.0%; 95% confidence interval [CI], 11.37-32.65%; p<0.0001). Compared with placebo, higher proportions of patients in the dupilumab group achieved ≥75% reduction in the Eczema Area and Severity Index score (57.3% vs 14.5%; difference, 42.9%; 95% CI, 29.75-55.97%; p<0.0001) and had ≥3-point (52.4% vs 9.6%; difference, 42.8%; 95% CI, 30.26-55.34%; p<0.0001) and ≥4-point (39.0% vs 4.8%; difference, 34.2%; 95% CI, 22.69-45.72%; p<0.0001) reductions in weekly average daily peak daily pruritus numerical rating scale scores. The incidence of TEAEs during the treatment period was similar in the two groups. The incidence of conjunctivitis, allergic conjunctivitis, and injection site reaction was higher in the dupilumab group than in the placebo group. CONCLUSIONS In adult Chinese patients, dupilumab was effective in improving the signs and symptoms of AD and demonstrated a favorable safety profile.

Abstract
BACKGROUND AND PURPOSE MR imaging is a useful and widely used evaluation for chordomas. Prior studies have classified chordomas into cell-dense type and matrix-rich type according to the ultrastructural features. However, the relationship between the MR imaging signal intensity and ultrastructural classification is unknown. We hypothesized that MR imaging signal intensity may predict both tumor ultrastructural classification and prognosis. MATERIALS AND METHODS Seventy-nine patients with skull base chordomas who underwent 95 operations were included in this retrospective single-center series. Preoperative tumor-to-pons MR imaging signal intensity ratios were calculated and designated as ratio on T1 FLAIR sequence (RT1), ratio on T2 sequence (RT2), and ratio on enhanced T1 FLAIR sequence (REN), respectively. We assessed the relationships among signal intensity ratios, ultrastructural classification, and survival. RESULTS Compared with the matrix-rich type group, the cell-dense type chordomas showed lower RT2 (cell-dense type: 1.90 ± 0.38; matrix-rich type: 2.61 ± 0.60 P < .001). The model of predicting cell-dense type based on RT2 had an area under the curve of 0.83 (95% CI, 0.75-0.92). In patients without radiation therapy, both progression-free survival (P = .003) and overall survival (P = .002) were longer in the matrix-rich type group than in the cell-dense type group. REN was a risk factor for progression-free survival (hazard ratio = 10.24; 95% CI, 1.73-60.79); RT2 was a protective factor for overall survival (hazard ratio = 0.33; 95% CI, 0.12-0.87); and REN was a risk factor for overall survival (hazard ratio = 4.76; 95% CI, 1.51-15.01). CONCLUSIONS The difference in MR imaging signal intensity in chordomas can be explained by electron microscopic features. Both signal intensity ratios and electron microscopic features may be prognostic factors.

Abstract
CONTEXT The annual consumption of opioid analgesics in the U.S. was more than 10 times the world average, whereas that in China was at a moderate level within Asia but much lower than the worldwide average. The opposite situations of opioid use in the U.S. and China revealed totally different problems in the developed versus developing world, that is, overuse versus underuse of opioids. OBJECTIVES This study analyzed the clinical consumption, estimated the needs of pain treatment, and evaluated the adequacy of opioid analgesic consumption in mainland China and its seven regions. METHODS A retrospective analysis of the national and regional consumption of opioid analgesics in mainland China during 2006-2016 was conducted. The adequacy of consumption measure was used to gauge the overall adequacy of opioid analgesic consumption in morphine equivalents (MEs) for the treatment of moderate-to-severe pain in mainland China and compared with international data. Annual per capita consumption was adopted to measure the clinical consumption of opioid analgesics in MEs at a national level and across seven regions of mainland China. Needs of morphine for cancer pain treatment in mainland China and in its seven regions were estimated and compared with the clinical consumption of opioid analgesics in MEs. RESULTS The adequacy of consumption measure of mainland China ranged from 0.0041 to 0.0088 during 2006-2016, which was less than 1% of that in the reference countries. The poor North East region had only 10.85% of the cancer pain morphine needs fulfilled. The highest fulfillment rate was 36.02% in rich Southern China, which was 25.9% at the national level. CONCLUSION The clinical consumption of opioid analgesics for the treatment of moderate-to-severe pain in mainland China was far below the international level. The annual per capita of clinical consumption was lower, and the adequacy of cancer pain treatment was poorer in less developed areas. All these findings call for actions to strengthen pain management.

Abstract
Abstract
Background
Anemia is one of the most common extraintestinal manifestations in patients with inflammatory bowel disease (IBD) at diagnosis. Studies have shown that anemia was associated with low levels of quality of life, which improves with the correction of anemia in adults. Recent data have shown an increase in the incidence and severity of pediatric IBD.
Aims
To investigate the prevalence of anemia in children at diagnosis of IBD and the trends in the past decade. The secondary aim was to investigate the associations between hemoglobin (Hb) levels and disease characteristics.
Methods
Eligible patients (age ≤18 years, diagnosed with IBD from 2009 to 2018) were retrospectively identified through our IBD database. Disease localization and phenotype were defined according to the Paris Classification of IBD. Anemia was defined by Hb levels according to WHO targets. The annual prevalence of anemia was calculated according to subtype (inflammatory vs iron deficiency). The Pediatric Crohn’s Disease Activity Index (PCDAI) and the Pediatric Ulcerative Colitis Activity Index (PUCAI) were used to assess the disease severity at diagnosis.
Results
We included 887 patients (439 females), mean (SD) age of 13.1 (3.4) years. Of these, 519 (58.5%) were identified with anemia within 30 days of diagnosis. The median (IQR) Hb level was 108 (98 -114) g/dL. Severe anemia (< 70 g/dL) was present in 1.8 % of patients. The prevalence of anemia at diagnosis remained relatively stable ranging from 60.2% in 2009 to 60.4% in 2018. The annual proportion of inflammatory vs iron-deficiency anemia is displayed in figure 1. Anemia was more prevalent in Crohn’s disease (CD) (62.2%) than Ulcerative colitis (UC) (57.9%) or IBD-unclassified (39.6%). The disease severity scores were higher in those with anemia. The median (IQR) PCDAI and PUCAI were respectively 37.5 (27.5–47.5) and 55.0 (40.0–65.0) in the anemic group as compared to 27.5 (20.0–37.50) and 35.0 (25.0–55.0) in the non-anemic group; P<0.0001. Patients with anemia had a lower BMI z-score [median (IQR) -0.84 (-1.84 - 0.08)] than the non-anemic patients [median (IQR) -0.38 (-1.21 - 0.43)]; P<0.001. The prevalence of anemia correlated significantly with disease location: upper intestinal involvement [L4a(67.7%) L4b(63.6%) L4aL4b(60.7%) none (52.8%)] P = 0.024 for CD; for UC [E1(21.1%) E2(44.4%) E3(75.0%) E4 (71.1%)] P<0.0001. A moderate correlation was found between Hb levels and C-reactive protein (r= -0.312, 95% CI: -0.378 to -0.243, P<0.0001).
Conclusions
Anemia remains a prevalent symptom in pediatric patients with IBD, and it is correlated with the extent of intestinal involvement and disease severity. The impact of anemia at Diagnosis and during follow-up on the levels of quality of life and physical activity is currently under investigation.

Abstract
PURPOSE To systematically compare the efficacy and safety of sufentanil versus fentanyl for pain relief in labor involving combined spinal-epidural analgesia (CSEA), a systematic review and meta-analysis of randomized controlled trials targeting parturients requesting labor analgesia was conducted. METHODS The primary outcome measure was visual analog scale scores assessed at 10, 15, 30, and 60 min after intrathecal injection. Secondary outcomes included duration of spinal analgesia, incidence of side effects in parturients, and neonatal Apgar scores. RESULTS Twelve randomized controlled trials, including data from 881 patients fulfilled the inclusion criteria. No clinically meaningful differences in pain reduction after intrathecal injection were found between the two analgesics. Sufentanil extended the duration of spinal analgesia by 25.40 min (95% CI 21.82 to 28.98 min; p < 0.00001) compared with fentanyl. The risk for pruritus, nausea, and vomiting among parturients was 82% for those using sufentanil (relative risk 0.82 [95% CI 0.67-0.99]; p = 0.04) and 48% for those using fentanyl (relative risk 0.48 [95% CI 0.29-0.80]; p = 0.005). Both the synthesis results and sensitivity analysis demonstrated no differences in the risk for respiratory depression between parturients using sufentanil versus fentanyl. The neonates in sufentanil group exhibited higher Apgar scores than the fentanyl group 5 min after delivery (weighted mean difference 0.10 [95% CI 0.05-0.16]; p = 0.0002). CONCLUSION Existing evidence suggests that compared with fentanyl, sufentanil used for analgesia in combined spinal-epidural during labor is more effective in extending the duration of spinal analgesia, and may be safer for the infant. There was overall low clinical and statistical heterogeneity among the included studies. For all outcomes, variations caused by heterogeneity across trials were acceptable. Thus the findings of this meta-analysis may provide additional evidence for future clinical practices of pain relief in labor involving CSEA. Stronger evidence supporting this conclusion will require data from more high-quality and multicenter randomized controlled trials.

Abstract
UNLABELLED Doctors do not know whether treatment of high parathyroid hormone levels is linked to better outcomes in their patients with kidney disease. In this study, lower parathyroid hormone levels at baseline were linked to lower risk of fracture, vascular events, and death in people with kidney disease. PURPOSE Chronic kidney disease (CKD) affects ~ 20% of older adults, and secondary hyperparathyroidism (HPT) is a common condition in these patients. To what degree HPT predicts fractures, vascular events, and mortality in pre-dialysis CKD patients is debated. In stage 3 and 4 CKD patients, we assessed relationships between baseline serum PTH levels and subsequent 10-year probabilities of clinical fractures, vascular events, and death. METHODS We used Marshfield Clinic Health System electronic health records to analyze data from adult CKD patients receiving care between 1985 and 2013, and whose PTH was measured using a second-generation assay. Covariates included PTH, age, gender, tobacco use, vascular disease, diabetes, hypertension, hyperlipidemia, obesity, GFR, and use of osteoporosis medications. RESULTS Five thousand one hundred eight subjects had a mean age of 68 ± 17 years, 48% were men, and mean follow-up was 23 ± 10 years. Fractures, vascular events, and death occurred in 18%, 71%, and 56% of the cohort, respectively. In univariate and multivariate models, PTH was an independent predictor of fracture, vascular events, and death. The hazards of fracture, vascular events and death were minimized at a baseline PTH of 0, 69, and 58 pg/mL, respectively. CONCLUSIONS We found that among individuals with stage 3 and 4 CKD, PTH was an independent predictor of fractures, vascular events, and death. Additional epidemiologic studies are needed to confirm these findings. If a target PTH range can be confirmed, then randomized placebo-controlled trials will be needed to confirm that treating HPT reduces the risk of fracture, vascular events, and death.

Abstract
Abstract
BACKGROUND
Internal carotid artery (ICA) injury is a disaster in endoscopic skull base surgery, so protection of internal carotid artery is an essential task. We use 3-dimensional multimodal imaging (3D-MMI) and intraoperative navigation (ION) in endoscopic skull base surgery to locate ICA and decrease ICA injury.
MATERIAL AND METHODS
26 patients underwent endoscopic skull base surgery (pituitary adenomas, chordomas, neurinomas and other tumors invading internal carotid artery) guided by 3D-MMI and ION techniques to locate ICA.
RESULTS
In all patients, the 3D-MMI and ION techniques enabled adequate visualization of vascular structures stereoscopically, especially the relationship between lesion and ICA, and suplly real-time navigation to locate ICA during endoscopic skull base surgery. No ICA injury happened and neurosurgeons removed tumors with relaxed mind.
CONCLUSION
3D-MMI and ION techniques were found to be helpful to locate internal carotid artery and decrease ICA injury during endoscopic skull base surgery.

Abstract
A Fe-Fe₃O₄/rGO nanocomposite with heterostructure has been successfully synthesized by a highyield, low-cost, and easily operated room-temperature reduction method. The novel Fe-Fe₃O₄/rGO composite exhibits an excellent activity for the degradation of Orange II under visible light by the Photo-Fenton process, which is 92.06% after 180 minutes. Moreover, magnetic analysis indicated that the prepared Fe-Fe₃O₄/rGO composite possesses ferromagnetic properties, which enable it to be magnetically separated for recycling purposes.

Abstract
Pheromones play an important role in mediating interspecific interactions in insects. In an insect community, pheromones can reveal information about the senders, which could be used by other members of the food web (competitor, natural enemies, etc.) to their own advantage. The aggregation pheromones of two closely related thrips species, Frankliniella occidentalis and Frankliniella intonsa, have been identified with the same major compounds, (R)-lavandulyl acetate and neryl (S)-2-methylbutanoate, but in different ratios. However, the roles of the aggregation pheromones in the interspecific interactions between these two closely related species are unknown. Here, we investigated the roles of major aggregation pheromone compounds in interspecific interactions between F. occidentalis and F. intonsa for both long and short ranges. The results showed that, at tested doses, neither aggregation pheromone-induced long range cross-attraction nor short range cross-mating was detected between F. occidentalis and F. intonsa. Field-trapping trials showed that the species-specificity in aggregation pheromones was regulated by the ratio of two major compounds. However, species-specific blends of the two major compounds had no effect on short-range interactions between these two species. Our data from the thrips species provide support for the 'aggregation model of coexistence', explaining the species-specific pheromone-mediated coexistence of closely related species. Thus, species-specific pheromones could be one of the factors affecting population dynamics and community structure in closely related insects with similar niches.

Abstract
Idiopathic pulmonary fibrosis (IPF) is a progressive disease that causes unremitting deposition of extracellular matrix proteins, thus resulting in distortion of the pulmonary architecture and impaired gas exchange. Associated with high morbidity and mortality, IPF is generally refractory to current pharmacological therapies. Lefty A, a potent inhibitor of transforming growth factor-β signaling, has been shown to have promising antifibrotic ability in vitro for the treatment of renal fibrosis and other potential organ fibroses. Here, we determined whether Lefty A can attenuate bleomycin (BLM)-induced pulmonary fibrosis in vivo based on a novel therapeutic strategy where human embryonic kidney 293 (HEK293) cells are genetically engineered with the Lefty A-associated GFP gene. The engineered HEK293 cells were encapsulated in alginate microcapsules and then subcutaneously implanted in ICR mice that had 1 wk earlier been intratracheally administered BLM to induce pulmonary fibrosis. The severity of fibrosis in lung tissue was assessed using pathological morphology and collagen expression to examine the effect of Lefty A released from the microencapsulated cells. The engineered HEK293 cells with Lefty A significantly reduced the expression of connective tissue growth factor and collagen type I mRNA, lessened the morphological fibrotic effects induced by BLM, and increased the expression of matrix metalloproteinase-9. This illustrates that engineered HEK293 cells with Lefty A can attenuate pulmonary fibrosis in vivo, thus providing a novel method to treat human pulmonary fibrotic disease and other organ fibroses.

Abstract
Objective: To investigate the effects of simvastatin on proliferation, invasion and radiosensitivity of mouse Lewis lung cancer cell line in vitro. Methods: The inhibitory effects of simvastatin on proliferation of Lewis lung cancer cells were detected by MTT assay. Matrigel invasion and migration assay was used to determine the invasion and motility ability of the Lewis cells. P38 activity was measured by p38 activity detection kit, and the expressions of p-p38, MKP-1, RhoA and MMP-2 were analyzed by Western blot. Lung cancer xenograft model was established in C57BL/6 mice. The mice were randomly divided into control group, simvastatin group, radiotherapy alone group and combined treatment group. The mice were killed 27 days after inoculation. The tumor mass, volume and lung metastatic nodules in the mice were compared. Results: The cell proliferation rates of 0 μmol/L, 10 μmol/L, 20 μmol/L and 30 μmol/L simvastatin groups were 100%, (87.0±9.0)%, (76.5±8.1)% and (67.0±7.3)%, respectively (P<0.05). Invasive cell numbers of the above groups were 298±30, 251±26, 207±20 and 132±19 per field, respectively (P<0.05). The intracellular p38 activities were 100%, (83.1±8.8)%, (70.2±8.2)% and (59.0±6.4)%, respectively. The relative expressions of p-p38 were 100%, (76.2±6.7)%, (56.4±5.4)% and (36.5±3.2)%, respectively. The expressions of RhoA were 100%, (80.1±5.3)%, (55.3±6.2)% and (38.6±4.8)%, respectively. The expressions of MMP-2 were 100%, (89.6±8.6)%, (51.9±4.7)% and (42.7±3.1)%, respectively, while the expressions of MKP-1 were 100%, (136.5±12.2)%, (168.8±15.3)% and (187.7±13.4)%, respectively (all P<0.05). Lung metastatic nodules and mass in the control, simvastatin, radiotherapy group and combined treatment groups were 6.24±1.09, 3.07±0.71 g, 5.09±1.16, 2.43±0.53 g, 3.12±0.68, 1.96±0.62 g and 2.65±0.38, 1.12±0.43 g, respectively (all P<0.05). The tumor inhibition rates were 39.0%, 48.1% and 26.5%, respectively, in the radiotherapy alone, combined treatment and simvastatin groups (all P<0.05). Conclusions: Simvastatin inhibits the proliferation of Lewis cell line by inhibiting the activity of p38 and expression of p-p38. Meanwhile, simvastatin reduces the invasion and motility of Lewis cell line through down-regulating the expression of RhoA and MMP-2. When combined with radiotherapy, simvastatin can inhibit tumor growth and metastasis, and improve the treatment efficacy of radiotherapy synergistically.

Abstract
Instead of killing cancer stem cells (CSCs), the conventional chemotherapy used for cancer treatment promotes the enrichment of CSCs, which are responsible for tumor growth, metastasis, and recurrence. However, most therapeutic agents are only able to kill a small proportion of CSCs by targeting one or two cell surface markers or dysregulated CSC pathways, which are usually shared with normal stem cells (NSCs). In this study, we developed a novel nondrug delivery system for the dual targeting of CSCs by conjugating hyaluronic acid (HA) and grafting the doublecortin-like kinase 1 (DCLK1) monoclonal antibody to the surface of poly(ethylene glycol) (PEG)–poly(d,l-lactide-co-glycolide) (PLGA) nanoparticles (NPs), which can specifically target CD44 receptors and the DCLK1 surface marker – the latter was shown to possess the capacity to distinguish between CSCSs and NSCs. The size and morphology of these NPs were characterized by dynamic light scattering (DLS), transmission electron microscopy (TEM), and scanning electron microscopy (SEM). This was followed by studies of NP encapsulation efficiency and in vitro drug release properties. Then, the cytotoxicity of the NPs was tested via Cell Counting Kit-8 assay. Finally, the 4T1 CSCs were obtained from the alginate-based platform, which we developed as an in vitro tumor model. Tumor-bearing nude mice were used as in vivo models to systematically detect the ability of NPs to target CSCs. Our results showed that the DCLK1–HA–PEG–PLGA NPs exhibited a targeting effect toward CSCs both in vitro and in vivo. These findings have important implications for the rational design of drug delivery systems that target CSCs with high efficacy.

Abstract
Objective: To assess the association of the traditional risk factors of coronary artery disease(CAD) and degree of coronary artery plaque. Methods: A total of 3 752 patients who had a suspicion of CAD from September 2011 to November 2012 at the First Hospital of China Medical University underwent the coronary artery computed tomography. The univariable and multivariable Logistic regression were employ to assess the association the traditional risk factors of CAD and degree of coronary artery plaque. Results: Age, diabetes, hypertension and smoking were the independent risk factor for significant stenosis, multivessel lesions and high coronary artery calcium score(all P <0.05), male was an independent risk factor for significant stenosis(P=0.039), however HDL-C was the independent protect factor(all P<0.05). Conclusion: Age, diabetes, hypertension and smoking are the independent risk factor for degree of coronary artery plaque, HDL-C is the independent protect factor.Male is only an independent risk factor for significant stenosis.

Abstract
Endonuclease G (EndoG) is a mitochondrial apoptosis regulator that also has roles outside of programmed cell death. It has been implicated as a defence DNase involved in the degradation of exogenous DNA after transfection of mammalian cells and in homologous recombination of viral and endogenous DNA. In this study, we looked at the effect of EndoG depletion on plasmid DNA uptake and the levels of homologous recombination in HeLa cells. We show that the proposed defence role of EndoG against uptake of non-viral DNA vectors does not extend to the cervical carcinoma HeLa cells, as targeting of EndoG expression by RNA interference failed to increase intracellular plasmid DNA levels. However, reducing EndoG levels in HeLa cells resulted in a statistically significant reduction of homologous recombination between two plasmid DNA substrates. These findings suggest that non-viral DNA vectors are also substrates for EndoG in its role in homologous recombination.

Abstract
Waste-to-energy (WtE) plant site selection is crucially important during the whole life cycle. Currently, the scholars launch some research in the WtE plant site selection. However, there are still two great problems in the present methods. Firstly, the uncertainty of information is not fully described. Secondly, the correlation among criteria lacks rationality, which is mainly manifested in two aspects: one is ignoring the correlation, and the other is measuring unreasonably. Firstly cloud model is introduced to describe the fuzziness and randomness of the information fully and precisely. Secondly, the 2-order additive fuzzy measures based on the Mobius transform and correlation coefficient matrix is introduced for fuzzy measure scientifically and reasonably. Thirdly, Cloud Choquet integral (CCI) operator is constructed to evaluate the alternatives. Finally, a case from China proves the effectiveness.

Abstract
Experiments by a four-pin probe and photodetachment technique were carried out to investigate the charged particle flows in the beam extraction region of a negative hydrogen ion source for neutral beam injector. Electron and positive ion flows were obtained from the polar distribution of the probe saturation current. Negative hydrogen ion flow velocity and temperature were obtained by comparing the recovery times of the photodetachment signals at opposite probe tips. Electron and positive ions flows are dominated by crossed field drift and ambipolar diffusion. Negative hydrogen ion temperature is evaluated to be 0.12 eV.

Abstract
To improve the performance of negative-ion based neutral beam injection on the Large Helical Device, the accelerator was modified on the basis of numerical investigations. A field limiting ring was installed on the upper side of a grounded grid (GG) support and a multi-slot GG was adopted instead of a multi-aperture GG. As a result, the voltage holding capability is improved and the heat load on the GG decreases by 40%. In addition, the arc efficiency is improved significantly only by replacing the GG.
