Abstract
Background Systemic lupus erythematosus is a heterogeneous chronic inflammatory autoimmune disorder characterized by an exacerbated expression of cytokines and chemokines in different tissues and organs. Renal involvement is a significant contributor to the morbidity and mortality of systemic lupus erythematosus, and its diagnosis is based on renal biopsy, an invasive procedure with a high risk of complications. Therefore, the development of alternative, non-invasive diagnostic tests for kidney disease in patients with systemic lupus erythematosus is a priority. Aim To evaluate the plasma levels of a panel of cytokines and chemokines using multiplex xMAP technology in a cohort of Colombian patients with active and inactive systemic lupus erythematosus, and to evaluate their potential as biomarkers of renal involvement. Results Plasma from 40 systemic lupus erythematosus non-nephritis patients and 80 lupus nephritis patients with different levels of renal involvement were analyzed for 39 cytokines using Luminex xMAP technology. Lupus nephritis patients had significantly increased plasma eotaxin, TNF-α, interleukin-17-α, interleukin-10, and interleukin-15 as compared to the systemic lupus erythematosus non-nephritis group. Macrophage-derived chemokine, growth regulated oncogene alpha, and epidermal growth factor were significantly elevated in systemic lupus erythematosus non-nephritis patients when compared to lupus nephritis individuals. Plasma eotaxin levels allowed a discrimination between systemic lupus erythematosus non-nephritis and lupus nephritis patients, for which we performed a receiver operating characteristic curve to confirm. We observed a correlation of eotaxin levels with active nephritis (Systemic Lupus Erythematosus Disease Activity Index). Our data indicate that circulating cytokines and chemokines could be considered good predictors of renal involvement in individuals with systemic lupus erythematosus.

Abstract
BACKGROUND LTCBDE combined with or without modified techniques is safe and efficacious for the management of gallstones and concomitant, even large, common bile duct (CBD) stones. METHODS To describe the surgical indications and procedure strategies of laparoscopic transcystic common bile duct exploration (LTCBDE), a retrospective analysis of 205 patients with concomitant gallstones and CBD stones treated using LTCBDE between June 2008 and June 2015 was performed. Clinical data on disease characteristics, methods for cystic duct incision and CBD stone extraction (with or without laser lithotripsy), and surgical outcomes were collected and reviewed. RESULTS CBD stones were successfully cleared in all patients. No patient was converted to choledochotomy or laparotomy. The cystic duct diameter ranged 3-8 mm, and 85 patients with cystic duct diameter ≥ 5 mm. The mean time for CBD stone extraction was 25.3 min, with the operative time ranged from 63 to 170 min. Lithotripsy was used in 74 (36.1%) patients among which 26 patients with cystic duct diameter ≥ 5 mm. Estimated blood loss during surgery was 10-120 ml per patient, and no intra-operative blood transfusions were needed. The mean postoperative hospital stay was 5.1 (range 3-7) days, and postoperative complications developed in seven patients. No bile duct injury, stricture, remnant, recurrent stones, or other adverse events were observed during the mean follow-up of 8 months. CONCLUSIONS Based on preoperative MRCP and intra-operative IOC findings about cystic duct diameter, the diameter of CBD, CBD stone size, we summarized and proposed the surgical indications and suitable techniques and strategies during LTCBDE.

Abstract
OBJECTIVE To evaluate the effectiveness of cardiac rehabilitation on coronary slow flow phenomenon. METHOD Included were 30 consecutive patients from June 2015 to June 2017. A thrombolysis in myocardial infarction (TIMI) frame evaluation was used to estimate coronary blood flow velocity. All coronary angiography diameters were normal, but blood flow levels did not reach the TIMI level 3. All patients were treated with aspirin and rosuvastatin. Patients were randomly assigned to an experimental group (cardiac rehabilitation treatment group, n = 15) or a control group (normal treatment without cardiac rehabilitation, n = 15). Plasma low density lipoprotein cholesterol (LDL-C), triglyceride (TG), high-sensitivity C reactive protein (hs-CRP), homocysteine (Hcy) and arginine (Arg) expression levels were collected after admission. These indices were reviewed again after 20-30 weeks, improved subjective symptoms were evaluated by multiple outcome criteria (MOCs), and coronary angiography was used to evaluate the velocity of coronary artery blood flow. RESULT The expression levels of LDL-C and TG in the experimental group were significantly lower than those of the control group (both P < 0.01). The plasma levels of hs-CRP, Hcy and Arg were lower than those in the control group (all P < 0.01). In the experimental group, subjective symptoms of chest pain were significantly improved and the coronary artery blood flow velocity was significantly increased compared with the control group (P < 0.01). CONCLUSION Cardiac rehabilitation can reduce the plasma levels of LDL-C, TG, hs-CRP, Hcy and Arg, significantly improve the symptoms of coronary slow flow phenomenon and accelerate the speed of coronary artery blood flow.

Abstract
Background Effective inhibition of plasma kallikrein may have significant benefits for patients with hereditary angioedema due to deficiency of C1 inhibitor (C1‐INH‐HAE) by reducing the frequency of angioedema attacks. Avoralstat is a small molecule inhibitor of plasma kallikrein. This study (OPuS‐2) evaluated the efficacy and safety of prophylactic avoralstat 300 or 500 mg compared with placebo. Methods OPuS‐2 was a Phase 3, multicenter, randomized, double‐blind, placebo‐controlled, parallel‐group study. Subjects were administered avoralstat 300 mg, avoralstat 500 mg, or placebo orally 3 times per day for 12 weeks. The primary efficacy endpoint was the angioedema attack rate based on adjudicator‐confirmed attacks. Results A total of 110 subjects were randomized and dosed. The least squares (LS) mean attack rates per week were 0.589, 0.675, and 0.593 for subjects receiving avoralstat 500 mg, avoralstat 300 mg, and placebo, respectively. Overall, 1 subject in each of the avoralstat groups and no subjects in the placebo group were attack‐free during the 84‐day treatment period. The LS mean duration of all confirmed attacks was 25.4, 29.4, and 31.4 hours for the avoralstat 500 mg, avoralstat 300 mg, and placebo groups, respectively. Using the Angioedema Quality of Life Questionnaire (AE‐QoL), improved QoL was observed for the avoralstat 500 mg group compared with placebo. Avoralstat was generally safe and well tolerated. Conclusions Although this study did not demonstrate efficacy of avoralstat in preventing angioedema attacks in C1‐INH‐HAE, it provided evidence of shortened angioedema episodes and improved QoL in the avoralstat 500 mg treatment group compared with placebo.

Abstract
Objective: To determine whether suction drainage is safe and effective compared with no-drainage in total hip arthroplasty. Methods: The research was based on PubMed, MEDLINE, EMBASE, Highwire, the Cochrane Library, CBM, CNKI, VIP and WFSD.The data were analysed using RevMan 5.2.Twenty-seven randomised controlled trials involving 3 603 hips were included in the analysis. Results: The meta-analysis indicate that suction drainage increases the rate of homologous blood transfusion (OR=1.98, 95%CI: 1.49-2.64, P<0.000 01)and the length of stay (OR=0.66, 95%CI: -0.01-1.33, P=0.05) (P<0.05). No significant difference was observed in the incidence of infection(OR=0.80, 95%CI: 0.52-1.22, P=0.30), wound haematomas(OR=0.47, 95%CI: 0.21-1.10, P=0.08), oozing (OR=0.93, 95%CI: 0.63-1.36, P=0.71) , deep venous thrombosis(OR=2.12, 95%CI: 0.68-6.56, P=0.19), VAS(OR=-0.06, 95%CI: -0.37-0.24, P=0.68) when the drainage group was compared with the no-drainage group. Conclusions: The comparison between suction drainage and no drainage in THA have indicated that no-drainage for easy total hip arthroplasty may be a better choice. However, orthopedic surgeon need to weigh the pros and cons of no-drainage in some complicated THAs.

Abstract
Our work is the first systematic meta-analysis to investigate the effect of selective serotonin reuptake inhibitor (SSRI) medication on bone mineral density. Through meta-analyzed 11 studies, our findings suggested that compared with nonusers, use of SSRIs was significantly associated with lumbar spine BMD reduction, particularly for old people. The use of selective serotonin reuptake inhibitors (SSRIs) has already been associated with bone mass loss. Their effects on bone mineral density (BMD) for the different bone sections have, however, thus been inconsistent. Here, we aim to assess the effects of SSRIs on BMD using a meta-analysis. We searched PubMed, Scopus, ISI Web of Knowledge, the Cochrane Library, and PsycINFO for all English-written studies investigating the effects of SSRIs on BMD and published before November 2017. BMD was compared between non-SSRI users and SSRI users using a random-effect model with standardized mean differences (SMD) and 95% confidence intervals (CIs). Furthermore, subgroup analyses were performed based on study design, age, and sex in order to find the origins of high heterogeneity. Eleven studies met the inclusion criteria and were used for the meta-analysis. Our study demonstrated that the use of SSRIs was significantly associated with lower BMD values (SMD - 0.40; 95% CI - 0.79 to 0.00; p = 0.05) and BMD Z-scores (SMD - 0.28; 95% CI - 0.50 to - 0.05; p = 0.02) of the lumbar spine, but not of the total hip and femoral neck. In addition, SSRI use was associated with a greater bone loss in older people. SSRI use is a risk factor of lower BMD of the lumbar spine, especially for older people. Future studies into the relationship between SSRI use and bone metabolism and bone mass need to be conducted with larger sample sizes for both men and women at different bone sites.

Abstract
Understanding the interfacial properties of catalyst/substrate is crucial for the design of high-performance catalyst for important chemical reactions. Recent years have witnessed a surge of research in utilizing MoS2 as a promising electro-catalyst for hydrogen production, and field effect has been employed to enhance the activity (Wang et al 2017 Adv. Mater. 29, 1604464; Yan et al 2017 Nano Lett. 17, 4109-15). However, the underlying atomic mechanism remains unclear. In this paper, by using the prototype MoS2/Au system as a probe, we investigate effects of external electric field on the interfacial electronic structures via density functional theory (DFT) based first-principles calculations. Our results reveal that although there is no covalent interaction between MoS2 overlayer and Au substrate, an applied electric field efficiently adjusts the charge transfer between MoS2 and Au, leading to tunable Schottky barrier type (n-type to p-type) and decrease of barrier height to facilitate charge injection. Furthermore, we predict that the adsorption energy of atomic hydrogen on MoS2/Au to be readily controlled by electric field to a broad range within a modest magnitude of field, which may benefit the performance enhancement of hydrogen evolution reaction. Our DFT results provide valuable insight into the experimental observations and pave the way for future understanding and control of catalysts in practice, such as those with vacancies, defects, edge states or synthesized nanostructures.

Abstract
BACKGROUND Paclitaxel (PTX) has remarkable anti-tumor activity, but it causes severe toxicities. There is an urgent need to seek an appropriate pharmacokinetic parameter of PTX to improve treatment efficacy and reduce adverse effects. OBJECTIVE To evaluate the association of pharmacokinetic parameter TC > 0.05 of paclitaxel (PTX) and its therapeutic efficacy and toxicity in patients with solid tumors. METHODS A total of 295 patients with ovarian cancer, esophageal cancer, breast cancer, and non-small cell lung cancer (NSCLC), who were admitted to the Tumor Hospital of Shantou University Medical College, China, were recruited for this study. Patients received 3 weeks of PTX chemotherapy. The plasma concentrations of PTX were examined using the MyPaclitaxel™ kit. The patients' PTX TC > 0.05 (the time during which PTX plasma concentration exceed 0.05µmol/L) were calculated based on pharmacokinetic analysis. RESULTS The results showed that: (1) the concentrations of PTX in these 295 patients ranged from 0.0358-0.127 µmol/L; (2) the PTX TC > 0.05 ranged from 14 to 38h with a median time of 27h; (3) among all treatment cycles, there was a statistically significant difference in the PTX TC > 0.05 between CR+PR and SD+PD; (4) with the increasing value of TC > 0.05, level of leukopenia and leukopenic fever increased; (5) high PTX TC > 0.05 led to the occurrence of neutropenia, neutropenic fever, severe anemia, and severe peripheral neurotoxicity. Taken together, our results indicated that the pharmacokinetic parameter PTX TC > 0.05 was an effective measure of treatment efficacy and toxicity in patients with solid tumors. Maintaining PTX TC > 0.05 at 26 to 30h could improve its efficacy and reduce the incidence of leukopenia, neutropenia, anemia, and peripheral neurotoxicity in these patients. CONCLUSION PTX TC > 0.05 is a key pharmacokinetic parameter of PTX which should be monitored to optimize individual treatment in patients with solid tumors.

Abstract
Porcine sapelovirus (PSV) is a causative agent of neurological disorders, fertility disorders and dermal lesions of swine. In this study, we isolated two PSV strains, Jpsv477 and Jpsv1315, from swine faecal specimens using a PLC/PRF/5 cell culture system. The PSV infection of PLC/PRF/5 cells induced a cytopathic effect (CPE). Two types of virus particles with identical diameter (~35 nm) but different densities (1.300 and 1.285 g/cm3 ) were observed in the cell culture supernatants. Analysis of the entire genome sequence of Jpsv477 and Jpsv1315 revealed that both strains possess 7,558 nucleotides and the poly (A) tail and have a typical PSV genome organization consisting of a 5' terminal untranslated region (5'UTR), a large open reading frame (ORF), and a 3' terminal untranslated region (3'UTR). The ORF encodes a single polyprotein that is subsequently processed into a leader protein (L), four structural proteins (VP1, VP2, VP3 and VP4) and seven functional proteins (2A, 2B, 2C, 3A, 3B, 3C and 3D). The structural proteins VP1, VP2, VP3 and VP4 have molecular masses of ~35, ~26, ~25 and ~6 kDa. The N-terminal amino acid sequence analysis of VP1, VP2, VP3 and VP4 confirmed that the cleavage sites between VP4 and VP2, VP2 and VP3, and VP3 and VP1 are K/A, Q/G and Q/G, respectively. We further confirmed that HepG2/C3A, Vero E6 and primary green monkey kidney cells (PGMKC) were also susceptible to PSV infection. The stability assay demonstrated that PSV was inactivated by heating at 60°C for 10 min or 65°C for 5 min. The virus also lost infectivity by incubation with 62.5 ppm of NaClO for 30 min.

Abstract
Methylphenidate (MPH) is currently used to treat children with attention deficit hyperactivity disorder (ADHD). Several extended-release (ER) formulations characterized by a dual release process were developed to improve efficacy over an extended duration. In this study, a model-based approach using literature data was developed to: 1) evaluate the most efficient pharmacokinetic (PK) model to characterize the complex PK profile of MPH ER formulations; 2) provide PK endpoint metrics for comparing ER formulations; 3) define criteria for optimizing development of ER formulations using a convolution-based model linking in vitro release, in vivo release, and hour-by-hour behavioral ratings of ADHD symptoms; and 4) define an optimized trial design for assessing the activity of MPH in pediatric populations. The convolution-based model accurately described the complex PK profiles of a variety of ER MPH products, providing a natural framework for establishing an in vitro/in vivo correlation and for defining criteria for assessing comparative bioequivalence of MPH ER products.

Abstract
Although recent studies demonstrated that fulvestrant is superior to anastrozole as first-line treatment for hormone receptor (HR)-positive advanced breast cancer, the cost-effectiveness of fulvestrant versus anastrozole remained uncertain. Thus, the current study aimed to evaluate the cost-effectiveness of fulvestrant compared with anastrozole in the first-line setting. A Markov model consisting of three health states (stable, progressive and dead) was constructed to simulate a hypothetical cohort of patients with HR-positive advanced breast cancer. Costs were calculated from a Chinese societal perspective. Health outcomes were measured in quality-adjusted life-year (QALY). The incremental cost-effectiveness ratio (ICER) was expressed as incremental cost per QALY gained. Model results suggested that fulvestrant provides an additional effectiveness gain of 0.11 QALYs at an incremental cost of $32,654 compared with anastrozole, resulting in an ICER of $296,855/QALY exceeding the willingness-to-pay threshold of $23,700/QALY. Hence, fulvestrant is not a cost-effective strategy compared with anastrozole as first-line treatment for HR-positive advanced breast cancer.

Abstract
OBJECTIVE Lung cancer seriously threats to patient's life and health. Cyramza is a therapeutic drug for inhibition of vessel formation and growth in clinical practice. The aim of this study was to investigate the effect of cyramza on growth and apoptosis of non-small lung cancer HCC4006 and explore the related mechanisms. MATERIALS AND METHODS Cell viability and apoptosis were examined by MTT assay and flow cytometry, respectively. Western blot was employed to examine the effect of cyramza on the apoptotic protein Bcl-w. After that Bcl-w knockdown and overexpression were respectively fulfilled by Bcl-w siRNA and plasmid transfection, effects of cyramza on cell apoptosis were determined by Western-blot. RESULTS Cyramza inhibited the cell growth and induced the cell apoptosis in HCC4006 cells, which was mediated by downregulation of Bcl-w level. Bcl-w knockdown and overexpression could increase and decrease the effect of cyramza on cell apoptosis, respectively. CONCLUSIONS Cyramza induced the apoptosis of non-small lung cancer cell line HCC4006 via the downregulation of Bcl-w.

Abstract
Objective: To investigate the clinical and genetic characteristics of 5 pedigrees of Gitelman syndrome (GS), and summarize its advances in genetics, diagnosis and management. Methods: Five families with GS were identified and total genome DNA were extracted from the peripheral blood of all the family members. The exons and their flanking introns of SLC12A3 gene were amplified by PCR and screened for mutation using Autoassembler 2.0 software. Results: Six heterozygous SLC12A3 gene mutations were found in the five pedigrees, including two complex combination of deletion and insertion mutation (c.486-490delTACGGinsA and c. 965-1_969delgCGGACinsACCGAAA and c. 976-977delGT). These mutations were predicted to change the normal protein structure. Conclusion: These 6 SLC12A3 mutations are the major cause of the five pedigrees of GS.

Abstract
We rigorously show that the truncation at low wave numbers always leads to background scalar-level anisotropy at large scales. Neither the resolution nor the spectral low-pass filter is dominant for this anisotropy, while the shape of the energy spectrum at low wave numbers is an important influence factor. Quantitative results are shown to provide references to the statistics in future postprocessing studies. Also, a simplified analytical model is introduced to explain the single-mode effects for this anisotropy.

Abstract
BACKGROUND Gastrointestinal (gi) symptoms are the most notable side effects of chemotherapeutic drugs; such symptoms are currently treated with drugs. In the present study, we investigated the effect of acupuncture on gi symptoms induced by chemotherapy in patients with advanced gastric cancer. METHODS A cohort of 56 patients was randomly divided into an experimental group and a control group. All patients received combination chemotherapy with oxaliplatin-paclitaxel. Patients in the experimental group received 30 minutes of acupuncture therapy daily for 2 weeks. The frequency and duration of nausea, vomiting, abdominal pain, and diarrhea, the average days and costs of hospitalization, and quality-of-life scores were compared between the groups. RESULTS Nausea was sustained for 32 ± 5 minutes and 11 ± 3 minutes daily in the control and experimental groups respectively (p < 0.05). On average, vomiting occurred 2 ± 1 times daily in the experimental group and 4 ± 1 times daily in the control group (p < 0.05). Abdominal pain persisted for 7 ± 2 minutes and 16 ± 5 minutes daily in the experimental and control groups respectively (p < 0.05). On average, diarrhea occurred 1 ± 1 times daily in the experimental group and 3 ± 1 times daily in the control group (p < 0.05). The average quality-of-life score was higher in the experimental group than in the control group (p < 0.05). No adverse events were observed for the patients receiving acupuncture. CONCLUSIONS Acupuncture, a safe technique, could significantly reduce gi symptoms induced by chemotherapy and enhance quality of life in patients with advanced gastric cancer.

Abstract
OBJECTIVE To investigate the prevalence of key unlawful acts among electric bicycle riders and provide evidence for the development of specific interventions. METHODS A 4-day road-side survey was conducted in Jinhua, Zhejiang province, in 2013. The speed of electric bicycle was measured by speed measuring instrument and the unlawful acts of riders, such as reverse riding, running the red-light and carrying passengers, were observed with non-participatory way. RESULTS A total of 3 448 running electric bicycles were observed and the average speed was 26 km/h, the proportion of electric bicycle at the speed of ≥15 km/h was 87.06%. The average speed was highest during 10 am-11 am(30 km/h). the number of observed electric bicycle riders with unlawful acts of ' running the red-light','reverse riding' and ' carrying passengers' were 1 315, 656 and 1 877 respectively, and the estimated rate was 10.01%, 4.99% and 15.22%, respectively. More ' running the red-light','reverse riding' and ' carrying passengers' occurred during 7 am-8 am(14.59%)and 13 pm-14 pm(15.25%), 13 pm-14 pm(7.33%)and 17 pm-18 pm(7.63%), 6 am-7 am(32.44%)and 12 pm-13 pm(27.90%), respectively. CONCLUSION Overspeeding, carrying passengers, running the red-light, reverse riding were the key unlawful acts among electric bicycle riders. Targeted intervention should be carried out to reduce the prevalence of unlawful riding acts and the incidence of electric bicycle related injuries and deaths.

Abstract
BACKGROUND Avoralstat is a potent small-molecule oral plasma kallikrein inhibitor under development for treatment of hereditary angioedema (HAE). This first-in-human study evaluated the safety, tolerability, pharmacokinetics, and pharmacodynamics of avoralstat. METHODS This double-blind, placebo-controlled, ascending-dose cohort trial evaluated avoralstat single doses of 50, 125, 250, 500, and 1000 mg and multiple doses up to 2400 mg daily (100, 200, 400, and 800 mg every 8 h [q8 h] up to 7 days). RESULTS Avoralstat (n = 71) was generally well tolerated with no signals for a safety concern; there were no serious adverse events (AEs) or discontinuations due to AEs, and compared to placebo (n = 18), no notable difference in AEs. Four moderate severity AEs were reported in two subjects; syncope after a single 250 mg dose (one subject) and abdominal pain, back pain, and eczema after multiple doses of 800 mg avoralstat (one subject). For multiple-dose cohorts, the incidence of gastrointestinal AEs was highest at the 2400 mg/day dose. Elimination of avoralstat was bi-exponential with a terminal half-life of 12-31 h. Inhibition of plasma kallikrein was observed at all doses, and the degree of inhibition was highly correlated with avoralstat concentrations (R = 0.93). Mean avoralstat concentrations at doses ≥400 mg q8 h met or exceeded plasma kallikrein EC50 values throughout the dosing interval. CONCLUSION Avoralstat was well tolerated, and drug exposure was sufficient to meet target levels for inhibition of plasma kallikrein. Based on these results, the 400 mg q8 h dose was selected for further evaluation in patients with HAE.
