Abstract
BACKGROUND Penpulimab is a novel programmed death (PD)-1 inhibitor. This study aimed to establish the efficacy and safety of first line penpulimab plus chemotherapy for advanced squamous non-small-cell lung cancer. METHODS This multicentre, randomised, double-blind, placebo-controlled, phase 3 clinical trial enrolled patients with locally advanced or metastatic squamous non-small-cell lung cancer from 74 hospitals in China. Eligible participants were aged 18-75 years, had histologically or cytologically confirmed locally advanced (stage IIIb or IIIc) or metastatic (stage IV) squamous non-small-cell lung cancer, were ineligible to complete surgical resection and concurrent or sequential chemoradiotherapy, had an Eastern Cooperative Oncology Group (ECOG) performance status of 0-1, did not have previous systemic chemotherapy for locally advanced or metastatic non-small-cell lung cancer, and had one or more measurable lesions according to RECIST (version 1.1). Participants were randomly assigned (1:1) to receive intravenous penpulimab 200 mg or placebo (excipient of penpulimab injection), plus paclitaxel 175 mg/m2 and carboplatin AUC of 5 intravenously on day 1 every 3 weeks for four cycles, followed by penpulimab or placebo as maintenance therapy. Stratification was done according to the PD-L1 tumour proportion score (<1% vs 1-49% vs ≥50%) and sex (male vs female). The participants, investigators, and other research staff were masked to group assignment. The primary outcome was progression-free survival assessed by the masked Independent Radiology Review Committee in the intention-to-treat population and patients with a PD-L1 tumour proportion score of 1% or more (PD-L1-positive subgroup). The primary analysis was based on the intention-to-treat analysis set (ie, all randomly assigned participants) and the PD-L1-positive subgroup. The safety analysis included all participants who received at least one dose of study drug after enrolment. This trial was registered with ClinicalTrials.gov (NCT03866993). FINDINGS Between Dec 20, 2018, and Oct 10, 2020, 485 patients were screened, and 350 participants were randomly assigned (175 in the penpulimab group and 175 in the placebo group). Of 350 participants, 324 (93%) were male and 26 (7%) were female, and 347 (99%) were of Han ethnicity. In the final analysis (June 1, 2022; median follow-up, 24·7 months [IQR 0-41·4]), the penpulimab group showed an improved progression-free survival compared with the placebo group, both in the intention-to-treat population (median 7·6 months, 95% CI 6·8--9·6 vs 4·2 months, 95% CI 4·2-4·3; HR 0·43, 95% CI 0·33-0·56; p<0·0001) and in the PD-L1-positive subgroup (8·1 months, 5·7-9·7 vs 4·2 months, 4·1-4·3; HR 0·37, 0·27-0·52, p<0·0001). Grade 3 or worse treatment-emergent adverse events occurred in 120 (69%) 173 patients in the penpulimab group and 119 (68%) of 175 in the placebo group. INTERPRETATION Penpulimab plus chemotherapy significantly improved progression-free survival in patients with advanced squamous non-small-cell lung cancer compared with chemotherapy alone. The treatment was safe and tolerable. Penpulimab combined with paclitaxel and carboplatin is a new option for first-line treatment in patients with this advanced disease.

Abstract
OBJECTIVE When selecting inhaled therapies, it is important to consider both the active molecules and the device. Extrafine formulation beclomethasone dipropionate plus formoterol fumarate (BDP/FF) has been available for some years delivered via pressurized metered-dose inhaler (pMDI). More recently, a breath-activated, multi-dose dry-powder inhaler (DPI), the NEXThaler, has been approved. The current study aimed to demonstrate the non-inferiority of BDP/FF delivered via the DPI vs. via the pMDI, in Chinese adults with asthma. METHODS After a four-week run-in period, when all patients received BDP/FF pMDI 100/6 µg, two inhalations twice daily (BID), patients were randomized equally to BDP/FF pMDI or DPI, both 100/6 µg, two inhalations BID for 12 weeks. The primary objective was to demonstrate non-inferiority of BDP/FF DPI vs. BDP/FF pMDI in terms of average pre-dose morning peak expiratory flow (PEF) over the entire treatment period. RESULTS Of 252 and 242 patients in the DPI and pMDI groups, respectively, 88.5% and 88.8% completed the study. The primary objective was met, with no statistically significant difference between the treatments in average pre-dose morning PEF, and with the lower limit of the 95% CI above the -15 L/min non-inferiority margin (adjusted mean difference: 5.25 L/min [95% CI: -0.56, 11.06]). Adverse events were reported by 48.4% and 49.6% patients in the DPI and pMDI groups, respectively, most mild or moderate. CONCLUSIONS The NEXThaler DPI is a similarly effective device to the pMDI for the administration of BDP/FF in adults, so extending the options available for the management of asthma.

Abstract
OBJECTIVE To analyze the RNA binding protein of Toxoplasma gondii (TgDDX39) using bioinformatics technology, and to evaluate the immunogenicity of TgDDX39, so as to provide insights into development of toxoplasmosis vaccines. METHODS The amino acid sequences of TgDDX39 were retrieved from the ToxoDB database, and the physicochemical properties, transmembrane structure domain, signal peptide sites, post-translational modification sites, coils, secondary and tertiary structures, hydrophobicity, and antigenic epitopes of the TgDDX39 protein were predicted using online bioinformatics tools, incluiding ProtParam, TMHMM 2.0, SignalP 5.0, NetPhos 3.1, COILS, SOPMA, Phyre2, ProtScale, ABCpred, SYFPEITHI and DNA-STAR. RESULTS TgDDX39 protein was predicted to be an unstable hydrophilic protein with the molecular formula of C2173H3458N598O661S18, which contained 434 amino acids and had an estimated molecular weight of 49.1 kDa and a theoretical isoelectric point of 5.55. The protein was predicted to have an extremely low possibility of signal peptides, without transmembrane regions, and contain 27 phosphorylation sites. The β turn and random coils accounted for 39.63% of the secondary structure of the TgDDX39 protein, and a coiled helix tended to produce in one site. In addition, the TgDDX39 protein contained multiple B and T cell antigenic epitopes. CONCLUSIONS Bioinformatics analyses predict that TgDDX39 protein has high immunogenicity and contains multiple antigenic epitopes. TgDDX39 protein is a potential candidate antigen for vaccine development.

Abstract
PURPOSE/OBJECTIVE(S) Approximately half of patients with advanced HER2-positive breast cancer (BC) will develop brain metastases (BM) over time. Local therapy including stereotactic radiotherapy (SRT) and whole brain radiotherapy (WBRT) is the main initial treatment in malignant tumor patients with BM. However, more than 50% patients after radiotherapy in one year suffered intracranial recurrence. Pyrotinib, a small molecule, irreversible, pan-ErbB receptor tyrosine kinase inhibitor (TKI), has a high potency for controlling BM and reducing the occurrence of brain metastases in advanced HER2-positive BC patients. We hypothesized that SRT or WBRT combined with pyrotinib and capecitabine could decrease intracranial progression in HER2 positive BC with newly diagnosed BM. MATERIALS/METHODS In this prospective single-arm phase Ib/II trial (NCT04582968), eligible patients were assigned to either fractionated stereotactic radiotherapy (FSRT) or whole-brain radiation therapy (WBRT), combined with pyrotinib and capecitabine. The primary endpoint was one-year CNS progression-free survival (PFS) rate. Secondary endpoints included intracranial objective response rate (IC-ORR) according to RANO-BM criteria, progression-free survival (PFS), overall survival (OS) and evaluation of safety and neurocognitive function. RESULTS From January 2020 to August 2022, 40 patients were enrolled. Twenty-nine patients were treated with FSRT in 8 Gy per fraction with 3 to 5 fractions and 11 were treated with WBRT in 3 Gy per fraction with 10 fractions, and then received chemotherapy in a time frame starting from 0 to 7 days after radiotherapy. At a median follow-up of 17.3 months, 1-year CNS-PFS rate was 74.9% (95% CI 61.9-90.7%) and median CNS-PFS was 18 months (95% CI, 15.5 to NA months). One-year PFS rate was 66.9% (53.1-84.2%) and median PFS time was 17.6 months (95% CI 12.8-34.1 months). The best intracranial response rate (IC-ORR: complete response and partial response) was 92.5% (37/40). The most common grade 3 or worse toxicity was diarrhea (7.5%) and asymptomatic radiation necrosis was detected in 4 of 67(6.0%) lesions treated with FSRT. No differences of neurocognitive function evaluated by MMSE (Mini-Mental State Exam) were observed between different groups at any time point. CONCLUSION Radiotherapy combined with pyrotinib and capecitabine resulted in a promising efficacy that crossed the pre-specified boundary in patients with HER2-positive advanced breast cancer with brain metastases. This is the first prospective study showing the efficacy and safety of CNS radiotherapy concurrent with pyrotinib and capecitabine in patients with BM from HER2-positive breast cancer. Further investigation in a randomized controlled study is warranted.

Abstract
Objective: The study aimed to analyze the clinical and endoscopic characteristics of adult celiac disease (CD) to provide a scientific basis for more effective CD diagnosis and treatment. Methods: In this cross-sectional study, the clinical and endoscopic data of 96 adult CD patients treated in the Department of Gastroenterology of the People's Hospital of Xinjiang Uygur Autonomous Region from March 2016 to December 2021 were retrospectively collected and analyzed. Results: A total of 96 CD patients were diagnosed, including 33 men and 63 women. The average age was 47±14 years (range, 18-81 years). The disease occurred mainly in the age group of 31-60 years. The median course of the disease was 2.0 (0.2-40.0) years. There were 41 (42.7%) classical and 55 (57.3%) non-classical CD patients. All patients with classical CD showed chronic diarrhea, often accompanied by abdominal pain (46.3%, 19/41), abdominal distension (17.1%, 7/41), anemia (65.9%, 27/41), and chronic fatigue (48.8%, 20/41). The main manifestations of non-classical CD were chronic abdominal pain (58.2%, 32/55), abdominal distension (32.7%, 18/55), anemia (40.0%, 22/55), and osteopenia/osteoporosis (38.2%, 21/55). Compared with non-classical CD, anemia developed more frequently in classical CD, and the difference was statistically significant (P = 0.012). The incidence of complications in CD patients was 36.5% (35/96), and the main complications were thyroid disease (19.8%, 19/96), connective tissue disease (6.2%, 6/96), and kidney disease (6.2%, 6/96). There was no significant difference between classical and non-classical CD (P>0.05). The frequency of endoscopic manifestations in CD patients was 84.4% (81/96). Duodenal bulb endoscopy showed nodular changes (72.9%, 70/96), grooved changes (10.4%, 10/96), and focal villous atrophy (9.4%, 9/96). The main manifestations of descending endoscopy were the decrease, flattening, or disappearance of duodenal folds (43.8%, 42/96), scallop-like changes (38.5%, 37/96), and nodular changes (34.4%, 33/96). Conclusions: Adult CD patients are mostly female. CD occurred mainly in the age group of 31-60 years. The clinical manifestations were mainly those of non-classical CD. Some patients often had other autoimmune diseases. Patients with characteristic endoscopic manifestations should be warned about the possibility of developing CD. Clinicians should strengthen the understanding of CD and reduce the related rates of missed diagnosis.

Abstract
OBJECTIVES In ORIENT-11, first-line sintilimab + pemetrexed-platinum significantly improved PFS compared with placebo + pemetrexed-platinum in patients with advanced metastatic nonsquamous non-small-cell lung cancer (AMnsqNSCLC). The study met the primary endpoint of PFS as of 15November2019. Here we report final survival analysis from ORIENT-11 (NCT03607539) using a 15September2021 data cutoff. METHODS Patients with treatment-naïve locally AMnsqNSCLC without sensitizing EGFR or ALK genomic tumor aberrations were randomly assigned to sintilimab + pemetrexed-platinum (n = 266) or placebo + pemetrexed-platinum (n = 131). Patients were stratified by PD-L1 expression, platinum-chemotherapy, and gender. Treatment continued until PD, unacceptable toxicity, or a maximum of 24 months. Patients in the placebo + pemetrexed-platinum arm could be sequenced to second-line sintilimab monotherapy, contingent upon PD. Response was assessed (RECISTv.1.1) by blinded independent radiographic review committee. Primary endpoint was PFS. OS was a secondary endpoint and defined from date of randomization to date of death due to any cause. Final OS analysis was defined as approximately 2 years after last patient randomized or when approximately 65 % of patients died, whichever first. RESULTS At data cutoff of final OS analysis, median study follow-up was 30.8 months. Of 397 patients, 243 OS events were observed (sintilimab + pemetrexed-platinum:151[57 %];placebo + pemetrexed-platinum:92 [70 %]). Of the patients in placebo + pemetrexed-platinum arm, 47 % crossed over to sintilimab monotherapy per protocol. Median OS was 24.2 months in sintilimab + pemetrexed-platinum arm and 16.8 months in placebo + pemetrexed-platinum arm (HR:0.65[95 % CI:0.50,0.85]). Estimated 2-year OS rates were 50 %(sintilimab + pemetrexed-platinum) and 32 %(placebo + pemetrexed-platinum). After adjusting for the crossover effect, OS treatment effect was more pronounced with HR 0.52 (95 % CI:0.38,0.69). OS benefit across all prespecified subgroups was largely consistent with that observed in the ITT population. CONCLUSIONS In the ORIENT-11 final OS analysis, sintilimab + pemetrexed-platinum demonstrated improved OS compared to placebo + pemetrexed-platinum when administered as first-line therapy in AMnsqNSCLC without EGFR or ALK genomic tumor aberrations.

Abstract
Purposes To explore the value of metagenomic next-generation sequencing (mNGS) in diagnosing pneumocystis jiroveciipneumonia (PJP) in the immunocompromised patients. Methods Data of 122 patients with PJP in an immunosuppressed state and 67 non-PJP patients were collected. The diagnostic efficacy of mNGS was compared with the conventional methods, including Gomori methenamine silver (GMS) staining and serum (1,3)-β-D-glucan (BDG). Changes of anti-microbial therapy for patients with PJP based on mNGS results were also reviewed. Results The diagnostic sensitivity of mNGS to PJP was higher than that of GMS and BDG (100% vs. 15 and 74.5%, p < 0.001). The diagnostic specificity (91.%) was lower than that of GMS (100%), and similar with BDG (89.6%). In addition to P. jirovecii, mNGS revealed co-pathogens like human β-herpesvirus 5, human γ-pesvirus 4, and some other opportunistic pathogens. The reads of mNGS were remarkably higher in BALF than in blood samples. Initial antimicrobial treatment was modified in 89.3% patients based on the mNGS results, and 74 cases (60.7%) were treated with anti-P. jirovecii therapy. Conclusion mNGS is highly efficient in diagnosing PJP and good at identifying pathogens in mixed infections.

Abstract
e21157 Background: In ORIENT-11, first-line (1L) SPP improved progression-free survival (PFS), overall survival (OS), objective response rate (ORR) and duration of response (DoR) compared with placebo plus pemetrexed-platinum (PPP) in pts with AMnsqNSCLC. We report outcomes from ORIENT-11 (NCT03607539) for pts treated with SPP with stage III (b & c) compared with stage IV disease. Methods: Pts with treatment-naïve locally AMnsqNSCLC without sensitizing EGFR/ALK alterations were randomly assigned to SPP (n = 266) or PPP (n = 131), stratified by PD-L1 expression, platinum-chemotherapy and sex. Primary endpoint was PFS (RECIST v1.1). Secondary endpoints included OS, ORR, DoR and safety. Kaplan-Meier method was used to analyze median PFS, OS and DoR. Stratified Cox model was used to analyze the hazard ratio (HR) of SPP vs. PPP. Clopper-Pearson method was used to calculate the 95% confidence intervals (CI) of ORR for each group. Miettinen-Nurminen method was used to analyze 95% CI of ORR difference between SPP and PPP. Data cutoff for OS data was September 15, 2021, providing a median follow-up of 30.8 months. Cutoff for other data was November 15, 2019, providing a median follow-up of 8.9 months. Results: 21 pts (7.9%) receiving SPP had stage III disease and 245 pts (92.1%) had stage IV disease. Baseline sex, age and PD-L1 expression ≥1% were similar between subgroups (Table). There were differences between subgroups in number of pts receiving carboplatin and ECOG performance status at baseline. PFS, OS, ORR and DoR outcomes were comparable between pts with stage III and stage IV disease based on the ad-hoc analyses. Any-grade adverse events (AEs) (100.0% vs. 99.6%) and AEs of Grade ≥3 (57.1% vs. 62.0%) were similar in pts with stage III and stage IV disease. Conclusions: In ORIENT-11, outcomes for pts receiving SPP as 1L therapy in AMnsqNSCLC with stage III and stage IV disease were comparable. Clinical trial information: NCT03607539. [Table: see text]

Abstract
Objective: To explore the expulsion effect of sodium dimercaptopropanesulfonate (DMPS) on mercury in different organs of mercury poisoning and the therapeutic effect of glutathione (GSH) combined with antioxidant therapy on mercury poisoning. Methods: In February 2019, 50 SPF male SD rats were randomly divided into 5 groups, 10 rats in each group: A (saline negative control group) , B (HgCL2 positive control group) , treatment group (C: intramuscular injection of DMPS 15 mg/kg treatment, D: intramuscular injection of DMPS30 mg/kg treatment, E: intramuscular injection of DMPS 15 mg/kg and intraperitoneal injection of GSH200 mg/kg treatment) . Rats in group B, C, D and E were subcutaneously injected with mercury chloride solution (1 mg/kg) to establish a rat model of subacute mercury poisoning kidney injury. Rats in group A were subcutaneously injected with normal saline. After the establishment of the model, rats in the treatment group were injected with DMPS and GSH. Rats in group A and group B were injected with normal saline. At 21 d (treatment 7 d) and 28 d (treatment 14 d) after exposure, urine and blood samples of 5 rats in each group were collected. Blood biochemistry, urine mercury, urine microalbumin and mercury content in renal cortex, cerebral cortex and cerebellum were detected. Results: After exposure to mercury, the contents of mercury in renal cortex, cerebrum and cerebellum of rats in group B, C, D and E increased, and urine microalbumin increased. Pathology showed renal tubular injury and renal interstitial inflammation. Compared with group B, urinary mercury and renal cortex mercury in group C, D and E decreased rapidly after DMPS treatment, and there was no significant decrease in mercury levels in cerebellum and cerebral cortex of rats, accompanied by transient increase in urinary albumin after DMPS treatment (P<0.05) ; the renal interstitial inflammation in group E was improved after GSH treatment. There was a positive correlation between urinary mercury and the contents of mercury in renal cortex, cerebral cortex and cerebellum (r=0.61, 0.47, 0.48, P<0.05) . Conclusion: DMPS mercury expulsion treatment can significantly reduce the level of metal mercury in the kidney, and there is no significant change in the level of metal mercury in the cortex and cerebellum.

Abstract
During winter 2018, the 16 prefecture-level cities in Anhui Province, Western Yangtze River Delta region, China had very high PM2.5 concentrations and prolonged pollution days. The impact of regional transport in the formation, accumulation, as well as dispersion of fine particulate matter (PM2.5) in Anhui Province was very significant. This study quantified and analyzed the vertical transport of PM2.5 in three major cities (Hefei, Fuyang, and Suzhou) of Anhui Province in January and July 2018 using the Weather Research and Forecasting (WRF) model coupled with the Community Multiscale Air Quality (CMAQ) model. The results of the inter-regional transport of PM2.5 revealed the dominant transport pathways for the three cities. The flux mainly flowed into Fuyang from Henan (2.23 and 1.42 kt/day in January and July, respectively) and Bozhou (1.96 and 1.21 kt/day in January and July, respectively), while the main flux from Fuyang flowed into Henan (-2.15 kt/day) and Lu'an (-1.91 kt/day) in January and Henan (-0.34 kt/day) and Bozhou (-0.29 kt/day) in July. In addition, the dominant transport pathways and the heights at which they occurred were identified: the northwest-southeast and northeast-south pathways in both winter and summer at both lower (˂300 m) and higher (≥300 m) levels for Fuyang; the northwest-south and northeast-southwest pathways in winter (at both lower and upper levels) and northwest-east and northeast-southwest pathways in summer at lower and upper levels for Hefei; and the northwest-southeast and northeast-south pathways in both winter (from 50 m up to the top level) and summer (between 100 and 300 m) for Suzhou. Furthermore, the intensities of daily PM2.5 transport fluxes in Fuyang during the atmospheric pollution episode (APE1) were stronger than the monthly average. These results show that joint emission controls across multiple cities along the identified pathways are urgently needed to reduce winter episodes.

Abstract
INTRODUCTION Sintilimab plus chemotherapy significantly prolonged progression-free survival (PFS) compared to chemotherapy alone in non-squamous non-small cell lung cancer (NSCLC) in the ORIENT-11 study. Updated overall survival (OS) and PFS data and corresponding biomarker analyses are reported here. METHODS In this study, 397 previously untreated, locally advanced or metastatic non-squamous NSCLC patients received sintilimab plus chemotherapy (combo group) or placebo plus chemotherapy (chemo group). Patients were stratified by PD-L1 expression levels. Immune signature profiles from tumor RNA sequencing and PD-L1 immunohistochemistry were correlated with clinical outcome to identify predictive biomarkers. RESULTS As of Jan 2021, with median follow-up of 22.9 months, median OS was significantly improved in the combo group compared to the chemo group (NR versus 16.8 months; HR 0.60, 95% CI: 0.45-0.79; p = 0.0003). High or medium immune cell infiltration was strongly associated with improved PFS in the combo group, in contrast to absent or low immune cell infiltration, which suggests that chemotherapy could not prime "immune deserts" to obtain benefit from PD-1 inhibition. In particular, high major histocompatibility complex (MHC) class-II presentation pathway expression was significantly correlated with prolonged PFS (HR=0.32, 95% CI: 0.19-0.54; p<0.0001) and OS (HR=0.36, 95% CI: 0.20-0.64; p=0.0005) in the combo group. Importantly, patients with low or absent PD-L1 but high MHC-II expression could still benefit from the combo treatment. In contrast, MHC class-I antigen presentation pathway was less relevant in this combination setting. CONCLUSIONS The addition of sintilimab to chemotherapy demonstrated significantly longer OS in non-squamous NSCLC. Expression of MHC class-II antigen presentation pathway could identify patients benefitting most from this combination.

Abstract
Unprecedented travel restrictions due to the COVID-19 pandemic caused remarkable reductions in anthropogenic emissions, however, the Beijing area still experienced extreme haze pollution even under the strict COVID-19 controls. Generalized Additive Models (GAM) were developed with respect to inter-annual variations, seasonal cycles, holiday effects, diurnal profile, and the non-linear influences of meteorological factors to quantitatively differentiate the lockdown effects and meteorology impacts on concentrations of nitrogen dioxide (NO2) and fine particulate matters (PM2.5) at 34 sites in the Beijing area. The results revealed that lockdown measures caused large reductions while meteorology offset a large fraction of the decrease in surface concentrations. GAM estimates showed that in February, the control measures led to average NO2 reductions of 19 μg/m3 and average PM2.5 reductions of 12 μg/m3. At the same time, meteorology was estimated to contribute about 12 μg/m3 increase in NO2, thereby offsetting most of the reductions as well as an increase of 30 μg/m3 in PM2.5, thereby resulting in concentrations higher than the average PM2.5 concentrations during the lockdown. At the beginning of the lockdown period, the boundary layer height was the dominant factor contributing to a 17% increase in NO2 while humid condition was the dominant factor for PM2.5 concentrations leading to an increase of 65% relative to the baseline level. Estimated NO2 emissions declined by 42% at the start of the lockdown, after which the emissions gradually increased with the increase of traffic volumes. The diurnal patterns from the models showed that the peak of vehicular traffic occurred from about 12pm to 5pm daily during the strictest control periods. This study provides insights for quantifying the changes in air quality due to the lockdowns by accounting for meteorological variability and providing a reference in evaluating the effectiveness of control measures, thereby contributing to air quality mitigation policies.

Abstract
Lockdown measures to curtail the COVID-19 pandemic in China halted most non-essential activities on January 23, 2020. Despite significant reductions in anthropogenic emissions, the Beijing-Tianjin-Hebei (BTH) region still experienced high air pollution concentrations. Employing two emissions reduction scenarios, the Community Multiscale Air Quality (CMAQ) model was used to investigate the PM2.5 concentrations change in this region. The model using the scenario (C3) with greater traffic reductions performed better compared to the observed PM2.5. Compared with the no reductions base-case (scenario C1), PM2.5 reductions with scenario C3 were 2.70, 2.53, 2.90, 2.98, 3.30, 2.81, 2.82, 2.98, 2.68, and 2.83 μg/m3 in Beijing, Tianjin, Shijiazhuang, Baoding, Cangzhou, Chengde, Handan, Hengshui, Tangshan, and Xingtai, respectively. During high-pollution days in scenario C3, the percentage reductions in PM2.5 concentrations in Beijing, Tianjin, Shijiazhuang, Baoding, Cangzhou, Chengde, Handan, Hengshui, Tangshan, and Xingtai were 3.76, 3.54, 3.28, 3.22, 3.57, 3.56, 3.47, 6.10, 3.61, and 3.67%, respectively. However, significant increases caused by unfavorable meteorological conditions counteracted the emissions reduction effects resulting in high air pollution in BTH region during the lockdown period. This study shows that effective air pollution control strategies incorporating these results are urgently required in BTH to avoid severe pollution.

Abstract
e21072 Background: Penpulimab is a human IgG1 monoclonal antibody (mAb) directed against human programmed cell death-1 (PD-1). Penpulimab, with its unique binding epitope, was engineered to eliminate Fc-mediated effector function that compromises anti-tumor immune cell function, and to optimize receptor occupancy by improving duration of drug binding. As a promising multi-target tyrosine kinase inhibitor (TKI), anlotinib significantly improved overall survival in advanced NSCLC patients (pts) in the phase 3 trial ALTER0303. Antiangiogenesis therapy combined with PD-1/PD-L1 inhibitors has shown excellent efficacy in advanced NSCLC pts. This is the trial evaluating chemo-free combination of penpulimab plus anlotinib in treatment-naive advanced NSCLC pts regardless of PD-L1 expression (NCT03866980). Methods: Pts with previously untreated, stage IIIB/IIIC/IV non-squamous NSCLC without sensitizing mutation of the epidermal growth factor receptor (EGFR) gene or translocation of the anaplastic lymphoma kinase (ALK) gene were enrolled. Eligible pts received penpulimab 200mg Q3W in combination with anlotinib 12mg QD (2 weeks on 1 week off) until loss of clinical benefit or unacceptable toxicity. The primary endpoint was progression-free survival (PFS). Secondary endpoints included ORR, disease control rate (DCR), duration of response (DoR) and overall survival. Results: As of January 13, 2021, 26 pts had received the combination therapy of penpulimab plus anlotinib (median age 59.5yrs [range 30-71], 76.9% male, 76.9% ECOG PS 1), with a median treatment duration of 3.5 months. Of 21 pts who have had at least one tumor assessment, the ORR was 57.1% (12 PRs) and DCR was 90.5% (12 PRs, 7 SDs). Median PFS has not been reached, and eleven responders remain in response. Treatment-related adverse events (TRAEs) occurred in 53.8% of pts (≥G3 TRAEs occurred in 15.4% [4/26]). Treatment-related SAEs occurred in 15.4% [4/26], and 7.7% of pts [2/26] had drug interruption or discontinuation due to TRAEs. Most common TRAEs (≥15%) were ALT increased, AST increased, hyperthyroidism and hypertension (15.4% each). Conclusions: The combination of penpulimab plus anlotinib as first-line treatment for locally advanced/metastatic NSCLC showed the promising efficacy with a manageable safety profile, thereby suggesting that this combination therapy may be a viable chemo-free treatment strategy for locally advanced/metastatic NSCLC pts. Clinical trial information: NCT03866980.

Abstract
BACKGROUND Patients with chronic obstructive pulmonary disease (COPD) often have coagulation abnormalities. However, the factors that lead to coagulation dysfunction in acute exacerbation of COPD (AECOPD) remain insufficiently explored. This study aimed to investigate the factors affecting coagulation status in patients with COPD and their influence on thrombosis. METHODS Data of COPD patients, including 135 cases in acute exacerbation stage and 44 cases in stable stage from Nov 2016 to Nov 2019 in our hospital, were collected. Healthy people (n = 135) were enrolled as the controls. The coagulation parameters, blood gas indexes and blood routine examination results were collected and analyzed. RESULTS White blood count (WBC), neutrophil count, neutrophil percentage (N%), platelet (PLT), prothrombin time (PT), international normalized ratio (INR), fibrinogen (FIB), and activated partial thromboplastin time (APTT) increased, plasma thrombin time (TT) decreased in AECOPD group compared with the control group. In AECOPD group, PT, APTT, and FIB were positively correlated with neutrophils and C-reaction protein levels. PT was positively correlated with PCO2 and negatively with pH. Thrombosis was observed in five acute exacerbation and three stable stage COPD patients. CONCLUSIONS Patients with AECOPD presented abnormal coagulation status, which was correlated to infection and hypercapnia and might be potentially the risk factor of thrombosis.

Abstract
As a result of the lockdown (LD) control measures enacted to curtail the COVID-19 pandemic in Wuhan, almost all non-essential human activities were halted beginning on January 23, 2020 when the total lockdown was implemented. In this study, changes in the concentrations of the six criteria air pollutants (PM2.5, PM10, SO2, NO2, CO, and O3) in Wuhan were investigated before (January 1 to 23, 2020), during (January 24 to April 5, 2020), and after the COVID-19 lockdown (April 6 to June 20, 2020) periods. Also, the relationships between the air pollutants and meteorological variables during the three periods were investigated. The results showed that there was significant improvement in air quality during the lockdown. Compared to the pre-lockdown period, the concentrations of NO2, PM2.5, PM10, and CO decreased by 50.6, 41.2, 33.1, and 16.6%, respectively, while O3 increased by 149% during the lockdown. After the lockdown, the concentrations of PM2.5, CO and SO2 declined by an additional 19.6, 15.6, and 2.1%, respectively. However, NO2, O3, and PM10 increased by 55.5, 25.3, and 5.9%, respectively, compared to the lockdown period. Except for CO and SO2, WS had negative correlations with the other pollutants during the three periods. RH was inversely related with all pollutants. Positive correlations were observed between temperature and the pollutants during the lockdown. Easterly winds were associated with peak PM2.5 concentrations prior to the lockdown. The highest PM2.5 concentrations were associated with southwesterly wind during the lockdown, and northwesterly winds coincided with the peak PM2.5 concentrations after the lockdown. Although, COVID-19 pandemic had numerous negative effects on human health and the global economy, the reductions in air pollution and significant improvement in ambient air quality likely had substantial short-term health benefits. This study improves the understanding of the mechanisms that lead to air pollution under diverse meteorological conditions and suggest effective ways of reducing air pollution in Wuhan.

Abstract
The holiday effect is a useful tool to estimate the impact on air pollution due to changes in human activities. In this study, we assessed the variations in concentrations of fine particulate matter (PM2.5) and nitrogen dioxide (NO2) during the holidays in the heating season from 2014 to 2018 based on daily surface air quality monitoring measurements in Beijing. A Generalized Additive Model (GAM) is used to analyze pollutant concentrations for 34 sites by comprehensively accounting for annual, monthly, and weekly cycles as well as the nonlinear impacts of meteorological factors. A Saturday effect was found in the downtown area, with about 4% decrease in PM2.5 and 3% decrease in NO2 relative to weekdays. On Sundays, the PM2.5 concentrations increased by about 5% whereas there were no clear changes for NO2. In contrast to the small effect of the weekend, there was a strong holiday effect throughout the region with average increases of about 22% in PM2.5 and average reductions of about 11% in NO2 concentrations. There was a clear geographical pattern in the strength of the holiday effect. In rural areas the increase in PM2.5 is related to the proportion of coal and biomass consumption for household heating. In the suburban areas between the Fifth Ring Road and Sixth Ring Road there were larger reductions in NO2 than downtown which might be due to decreased traffic as many people return to their hometown for the holidays. This study provides insights into the pattern of changes in air pollution due to human activities. By quantifying the changes, it also provides insights for improvements in air quality due to control policies implemented in Beijing during the heating season.

Abstract
OBJECTIVE To explore the prognostic value of the morphology of tumor invasion front (TIF) in Intrahepatic Cholangiocarcinoma (ICC). PATIENTS AND METHODS Seventy-four ICC patients with complete clinicopathological data and follow-up information were enrolled in our study. The most typical morphology of TIF of each case will be classified as low-grade group or high-grade group after evaluation by two pathologists. The clinicopathological characteristics, disease-free survival (DFS), and overall survival (OS) were compared between the two groups. RESULTS A total of 26 (35.3%) patients were assigned to low-grade group, while 48 (64.7%) patients were assigned to high-grade group. High-grade group was associated with higher CA19-9 (p=0.032), poor differentiation (p=0.050), larger tumor diameter (p=0.016), advanced T staging (p=0.048), and higher incidence of lymph node (LN) metastasis (0.014). No significant associations were found in demographic and clinical characteristics between the two groups. On multivariable analysis, high-grade group was a significant independent predictor of worse DFS (HR=0.433, 95% CI=0.235-0.800, p=0.002) and OS (HR=0.363, 95% CI=0.187-0.704, p=0.003). CONCLUSIONS High-grade morphology of TIF was an independent prognostic factor of ICC.

Abstract
INTRODUCTION Sintilimab, an anti-programmed death 1 antibody, plus pemetrexed and platinum had revealed promising efficacy for nonsquamous NSCLC in a phase 1b study. We conducted a randomized, double-blind, phase 3 study to compare the efficacy and safety of sintilimab with placebo, both in combination with such chemotherapy (ClinicalTrials.gov: NCT03607539). METHODS A total of 397 patients with previously untreated, locally advanced or metastatic nonsquamous NSCLC without sensitizing EGFR or anaplastic lymphoma kinase genomic aberration were randomized (2:1 ratio) to receive either sintilimab 200 mg or placebo plus pemetrexed and platinum once every 3 weeks for four cycles, followed by sintilimab or placebo plus pemetrexed therapy. Crossover or treatment beyond disease progression was allowed. The primary end point was progression-free survival (PFS) as judged by an independent radiographic review committee. RESULTS As of November 15, 2019, the median follow-up was 8.9 months. The median PFS was significantly longer in the sintilimab-combination group than that in the placebo-combination group (8.9 versus 5.0 mo; hazard ratio, 0.482, 95% confidence interval [CI]: 0.362-0.643; p < 0.00001). The confirmed objective response rate was 51.9% (95% CI: 45.7%-58.0%) in the sintilimab-combination group and 29.8% (95% CI: 22.1%-38.4%) in placebo-combination group. The incidence of grade 3 or higher adverse events was 61.7% in sintilimab-combination group and 58.8% in placebo-combination group. CONCLUSIONS In Chinese patients with previously untreated, locally advanced or metastatic nonsquamous NSCLC, the addition of sintilimab to chemotherapy with pemetrexed and platinum resulted in considerably longer PFS than with chemotherapy alone with manageable safety profiles.

Abstract
BACKGROUND AND PURPOSE Pathology and microbiology results for suspected spondylodiscitis on MR imaging are often negative in up to 70% of cases. We aimed to predict whether MR imaging features will add diagnostic value when combined with clinical biomarkers to predict positive findings of spondylodiscitis on pathology and/or microbiology from percutaneous biopsy. MATERIALS AND METHODS In this retrospective single-center institutional review board-approved study, patients with radiologically suspected spondylodiscitis and having undergone percutaneous biopsies were assessed. Demographic characteristics, laboratory values, and tissue and blood cultures were collected. Pathology and microbiology results were used as end points. Three independent observers provided MR imaging-based scoring for typical MR imaging features for spondylodiscitis. Multivariate logistic regression and receiver operating characteristic analysis were performed to determine an optimal combination of imaging and clinical biomarkers in predicting positive findings on pathology and/or microbiology from percutaneous biopsy suggestive of spondylodiscitis. RESULTS Our patient cohort consisted of 72 patients, of whom 33.3% (24/72) had spondylodiscitis. The mean age was 63 ± 16 years with a male/female ratio of 41:31. Logistic regression revealed a combination with an area under the curve of 0.72 for pathology and 0.68 for pathology and/or microbiology. Epidural enhancement on MR imaging improved predictive performance to 0.87 for pathology and 0.78 for pathology and/or microbiology. CONCLUSIONS Our findings demonstrate that epidural enhancement on MR imaging added diagnostic value when combined with clinical biomarkers to help predict which patients undergoing percutaneous biopsy will have positive findings for spondylodiscitis on pathology and/or microbiology.

Abstract
Objective: To summarize the clinical characteristics and liver biochemical parameters of 324 cases admitted with novel coronavirus pneumonia in Shanghai area. Methods: Clinical data and baseline liver biochemical parameters of 324 cases with novel coronavirus pneumonia admitted to the Shanghai Public Health Clinical Center from January 20, 2020 to February 24, 2020 were retrospectively analyzed. Patients were divided into two groups based on the status of illness: mild type (mild and typical) and severe type (severe and critical).The differences in clinical data and baseline liver biochemical parameters of the two groups were described and compared. The t-test and Wilcoxon rank-sum test were used for measurement data. The enumeration data were expressed by frequency and rate, and chi-square test was used. Results: Of the 324 cases with novel coronavirus pneumonia, 26 were severe cases (8%), with median onset of 5 days, 20 cases were HBsAg positive (6.2%), and 70 cases (21.6%) with fatty liver, diagnosed with X-ray computed tomography. Alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), γ-glutamyl transferase (GGT), total bilirubin (TBil), albumin(ALB) and international normalized ratio (INR) of 324 cases at baseline were 27.86 ± 20.02 U/L, 29.33 ± 21.02 U/L, 59.93 ± 18.96 U / L, 39.00 ± 54.44 U/L, 9.46 ± 4.58 μmol / L, 40.64 ± 4.13 g / L and 1.02 ± 0.10. Of which, ALT was > than the upper limit of normal (> ULN), accounting for 15.7% (51/324). ALT and AST > ULN, accounting for 10.5% (34/324). ALP > ULN, accounting for 1.2% (4/324). ALP and GGT > ULN, accounting for 0.9% (3/324). INR > ULN was lowest, accounting for 0.6% (2/324). There were no statistically significant differences (P > 0.05) in ALT [(21.5 vs. 26) U / L, P = 0.093], ALP [(57 vs.59) U/L, P = 0.674], and GGT [(24 vs.28) U/L, P = 0.101] between the severe group and the mild group. There were statistically significant differences in AST (23 U/L vs. 34 U/L, P < 0.01), TBil (10.75 vs. 8.05 μmol / L, P < 0.01), ALB (35.79 ± 4.75 vs. 41.07 ± 3.80 g/L, P < 0.01), and INR (1.00 vs. 1.04, P < 0.01). Conclusion: The baseline liver biochemical parameters of 324 cases with novel coronavirus pneumonia in Shanghai area was comparatively lower and the liverinjury degree was mild, and the bile duct cell damage was rare.

Abstract
BACKGROUND Family with sequence similarity 83 member A (FAM83A) can promote tumor cell proliferation and facilitate epidermal growth factor tyrosine kinase inhibitor resistance in some malignant tumors, but its role in lung cancer has not been directly explored. OBJECTIVE We investigated FAM83A expression in lung adenocarcinoma (LUAD) and its significance in clinicopathologic characteristics and prognosis of the disease. PATIENTS AND METHODS We analyzed the mRNA expression of FAM83A in LUAD and normal (or adjacent) lung tissues from Oncomine database firstly. Then, we detected FAM83A protein expression in five paired fresh LUAD and adjacent lung tissue specimens from patients in our hospital by Western blotting. In addtion, FAM83A expression in 86 paraffin-embedded archived LUAD samples was evaluated by Immunohistochemistry, and the correlations between FAM83A expression and clinicopathologic characteristics and prognosis of the patients were analyzed. RESULTS Oncomine data analysis manifested that FAM83A mRNA expression was increased in LUAD. Western blotting revealed higher FAM83A expression in fresh LUAD tissues than in the adjacent lung tissues (P= 0.036). Immunohistochemistry analysis on 86 paraffin samples further demonstrated that the LUAD tissue had higher FAM83A expression than adjacent lung tissue (P< 0.001). The correlation analysis revealed that advanced stage tumors (stage III-IV) had higher FAM83A expression than early stage tumors (stage I-II) (P= 0.004). High FAM83A expression was significantly associated with lymphnode involvement and clinical staging (P= 0.008 and 0.008 respectively). Univariate and multivariate Cox regression analysis manifested that FAM83A expression was an independent predictive factor for poor survival. Kaplan-Meier survival curves showed that patients with higher FAM83A expression had shorter overall survival than those with lower FAM83A expressions (P= 0.002). CONCLUSION FAM83A is upregulated in advanced LUAD and is related to unfavorible prognosis. FAM83A might be a novel diagnostic and prognositic biomarker for LUAD.

Abstract
Background Glycopyrrolate/formoterol fumarate metered dose inhaler (GFF MDI) is a long-acting muscarinic antagonist/long-acting β2-agonist fixed-dose combination therapy delivered by MDI, formulated using innovative co-suspension delivery technology. The PINNACLE-4 study evaluated the efficacy and safety of GFF MDI in patients with moderate-to-very severe chronic obstructive pulmonary disease (COPD) from Asia, Europe, and the USA. This article presents the results from the China subpopulation of PINNACLE-4. Methods In this randomized, double-blind, placebo-controlled, parallel-group Phase III study (NCT02343458), patients received GFF MDI 18/9.6 µg, glycopyrrolate (GP) MDI 18 µg, formoterol fumarate (FF) MDI 9.6 µg, or placebo MDI (all twice daily) for 24 weeks. The primary endpoint was change from baseline in morning pre-dose trough forced expiratory volume in 1 second at Week 24. Secondary lung function endpoints and patient-reported outcome measures were also assessed. Safety was monitored throughout the study. Results Overall, 466 patients from China were included in the intent-to-treat population (mean age 63.6 years, 95.7% male). Treatment with GFF MDI improved the primary endpoint compared to GP MDI, FF MDI, and placebo MDI (least squares mean differences: 98, 104, and 173 mL, respectively; all P≤0.0001). GFF MDI also improved daily total symptom scores and time to first clinically important deterioration versus monocomponents and placebo MDI, and Transition Dyspnea Index focal score versus placebo MDI. Rates of treatment-emergent adverse events were similar across the active treatment groups and slightly higher in the placebo MDI group. Conclusion GFF MDI improved lung function and daily symptoms versus monocomponents and placebo MDI and improved dyspnea versus placebo MDI. All treatments were well tolerated with no unexpected safety findings. Efficacy and safety results were generally consistent with the global PINNACLE-4 population, supporting the use of GFF MDI in patients with COPD from China.

Abstract
BACKGROUND Bevacizumab is a monoclonal antibody (mAb) against vascular endothelial growth factor (VEGF) and used for treatments of various cancers. Due to the high costs of bevacizumab treatments, a biosimilar provides an affordable alternative therapy for cancer patients. METHODS In this randomized, double-blind, multicenter, phase 3 study, locally advanced, metastatic or recurrent non-squamous non-small cell lung cancer (NSCLC) patients with wild-type epidermal growth factor receptor were enrolled and randomized (1:1) into IBI305 or bevacizumab groups. Patients received 6 cycles of paclitaxel/carboplatin plus IBI305 or bevacizumab 15 mg/kg intravenously followed by IBI305 or bevacizumab 7.5 mg/kg maintenance until disease progression, unacceptable toxicity or death. The primary endpoint was confirmed objective response rate (ORR) by an independent radiological review committee (IRRC) and secondary endpoints included disease control rate (DCR), progression-free survival (PFS), duration of response (DOR), overall survival (OS) and safety. RESULTS A total of 450 NSCLC patients were enrolled (224 in IBI305 group and 226 in bevacizumab group). ORRs were 44.3% for IBI305 and 46.4% for bevacizumab, and the ORR ratio was 0.95 (90% CI: 0.803 to 1.135), within the predefined equivalence margin of 0.75 to 1.33. No significant difference in PFS (7.64 vs. 7.77 m, P=0.9987) was observed between the 2 groups. Serious adverse events (AEs) occurred in 33.5% (75/224) of patients in the IBI305 group and 37.6% (85/226) in the bevacizumab group. AEs ≥ grade 3 were similar in the IBI305 and bevacizumab groups [84.4% (189/224) vs. 89.8% (203/226), P=0.085]. CONCLUSIONS IBI305 is similar to bevacizumab in terms of efficacy and safety.

Abstract
PURPOSE The aim of this study was to investigate the efficacy and safety of tratinterol hydrochloride in bronchial asthma (BA) treatment. METHODS Patients enrolled in this study were distributed randomly into a treatment group (tratinterol hydrochloride) and an active control group (procaterol hydrochloride) and were treated for 2 weeks after running-in. The end points were changes in pulmonary function and clinical symptoms after administration. Safety indices were physical examinations, laboratory testing and spontaneous reporting. FINDINGS We enrolled 732 subjects, -365 in the treatment group and 367 in the active control group. Forced expiratory volume (FEV1), significantly increased in both group after treatment (P < 0.05). Least-squares (LS) means were -0.03/in the full-analysis set (FAS) and -0.02 in the per-protocol set (PPS) set, and 95% confidence intervals (CIs) for these sets were -0.09 to 0.03 and -0.08 to 0.04, respectively. Forced expiratory volume (FVC), morning peak expiratory flow (PEF) and asthma scores were significantly different with pretreatment (P < 0.05). There was no difference in asymptomatic days or frequency of relief medicine use (P > 0.05). No serious adverse events occurred. IMPLICATIONS Tratinterol hydrochloride was effective, safe and not inferior to procaterol hydrochloride in treating BA.

Abstract
Objective: To explore the clinical manifestations, diagnosis, treatment and prognosis of anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) . Methods: A retrospective study identified 91 patients diagnosed with ALCAPA at Shanghai Children's Medical Center from March 2010 to August 2017. According to the left ventricular ejection fraction (LVEF) at the time of consultation, patients were divided into the cardiac insufficiency group (n=54) and the normal cardiac function group (n=37). Clinical features (age of onset, clinical performance, etc) and auxiliary examinations (electrocardiogram, echocardiography, etc) between the two groups were compared using a t-test and a Chi-square test. Prognostic factors were analyzed by an ordered logistic regression and a Pearson correlation coefficient. Results: (1) The age of diagnosis of patients in the cardiac insufficiency group who were usually misdiagnosed as cardiomyopathy was (10.0±2.6) months (20/54) , whereas the age of diagnosis of patients in the normal cardiac function group who were usually misdiagnosed as valvular diseases was (40.0±7.8) months (4/37). According to the pathophysiological mechanism, forty of the 54 (74%) patients in the cardiac insufficiency group were infantile type, and 78% patients (29/37) in the normal cardiac function group were adult type. (2) Preoperative electrocardiogram showed the deep Q wave in lead I occurred more frequently in the cardiac insufficiency group than in the normal cardiac function group (28/54 vs. 11/37, χ(2)=4.388, P=0.036). (3) Twenty patients died in the cardiac insufficiency group including 12 patients who died from postoperative cardiac pump failure and 8 children who did not undergo surgery due to poor prognosis and died from other reasons. There was no death in the normal cardiac function group. (4) Preoperative LVEF was the unique risk factor affecting prognosis (F=16.872, P=0.005). The preoperative LVEF was significantly lower than the postoperative LVEF ((37±11)% vs. (45±14)%, t=3.614, P=0.001) in the cardiac insufficiency group. During the follow-up period, 6 patients in the cardiac insufficiency group still presented with postoperative cardiac dysfunction, and the patients in the normal cardiac function group still had normal cardiac function. Conclusions: Preoperative LVEF was the unique risk factor affecting prognosis of ALCAPA. Patients with infantile type ALCAPA and preoperative cardiac insufficiency should receive long-term follow-up treatment.

Abstract
9095 Background: IBI305 is a recombinant humanized anti-VEGF monoclonal antibody, a biosimilar candidate to bevacizumab in analytical and functional comparisons. Pharmacokinetic similarity has been demonstrated in healthy males. Here we present primary efficacy and safety results from a phase 3 comparative study in non-small cell lung cancer (NSCLC). Methods: In this double-blind, active-controlled study, subjects with advanced non-squamous NSCLC on first-line treatment with carboplatin and paclitaxel were randomized (1:1) to IBI305 or bevacizumab (15 mg/kg IV Q3W). After six cycles, patients were on maintenance treatment with IBI305 or bevacizumab (7.5 mg/kg IV Q3W) till progression. Clinical equivalence of the primary endpoint, confirmed objective response rate (ORR) was evaluated by comparing the 2-sided 90% confidence interval (CI) of the risk ratio (RR) between study arms with the prespecified margin (0.75, 1.33). Results: A total of 450 subjects were randomized (IBI305: n = 224; bevacizumab: n = 226). Baseline characteristics were well balanced between treatment arms. ORR evaluated by Independent Radiological Review Committee (IRRC) in full analysis set (FAS) was 44.3% (98/221) for IBI305 and 46.4% (102/220) for bevacizumab; the RR for ORR was 0.95 (90% CI: 0.803, 1.135). Sensitive analysis result on RRs of ORR in Intention to Treat (ITT) population (IBI305: n = 224; bevacizumab: n = 226) and other analysis set were consistent and all within the prespecified equivalence margin. The medium PFS were 8.4 months for IBI305 and 8.3 months for bevacizumab and duration of response (DOR) was also similar in both arms. Treatment-emergent adverse events (TEAEs) were well balanced between treatment arms and consistent with the known adverse event profile of bevacizumab. Patients developing binding antibodies were 0.5% in the IBI305 arm vs 0% in the bevacizumab arm; no subject tested positive for neutralizing antibodies. Conclusions: This is the first released phase 3 clinical study with maintenance treatment for bevacizumab biosimilar in NSCLC patients till now. The comparative study met its predefined primary endpoint that the RR for confirmed ORR was within the prespecified equivalence margin. There was no significant difference between the two arms in safety profile and immunogenicity. Clinical trial information: NCT02954172.

Abstract
Small cell lung cancer (SCLC) is a highly lethal malignancy with the 5-year survival rate of less than 7%. Chemotherapy-resistance is a major challenge for SCLC treatment in clinic. In the study, we developed a high-throughput drug screen strategy to identify new drugs that can enhance the sensitivity of chemo-drug cisplatin in SCLC. This screen identified auranofin, a US Food and Drug Administration (FDA)-approved drug used therapeutically for rheumatoid arthritis, as a sensitizer of cisplatin. Further study validated that auranofin synergistically enhanced the anti-tumor activity of cisplatin in chemo-resistant SCLC cells, which was accompanied by the enhanced induction of cell cycle arrest and apoptosis. The synergistic action of auranofin and cisplatin was through ROS overproduction, thereby leading to mitochondrial dysfunction and DNA damage. Furthermore, in vivo study demonstrated that the combination treatment of auranofin and cisplatin dramatically inhibited tumor growth in SCLC. Therefore, our study provides a rational basis for further clinical study to test whether auranofin could enhance the sensitivity of cisplatin-based therapy in SCLC patients.

Abstract
In vitro produced β-like cells can provide promising cell therapy for curing the epidemic of diabetes. In this context, we aimed to investigate the effects of different concentrations of γ-aminobutyric acid (GABA) on the differentiation of rat pancreatic ductal epithelial-like stem cells (PDESCs) into β-like cells. The PDESC line cells were cultured in the basal media (DMEM/F12 + 10% FBS + 1% penicillinstreptomycin) supplemented with 0 μM, 5 μM, 50 μM, 500 μM, and 5 mM of GABA for 28 days to induce their differentiation. The differentiated cells were detected by cell morphology, dithizone (DTZ) staining, immunofluorescence staining, real-time polymerase chain reaction (qPCR), and glucose-stimulated insulin secretion (GSIS) assay to validate their identity. At the end of 28 days, compared with the control group, enrichment of induced cells was high among the 5 μM, 50 μM, 500 μM, and 5 mM GABA induction groups. The formation of islet-like cell clusters (ICCs) began at 14 days, and the cell clusters showed a growth trend with the culture time. The induced ICCs were positive for DTZ staining, while the control group showed negative results for DTZ staining and the differentiated cells were also positive for β-cell-specific markers (Ins1 and Pdx1). GSIS assay of 50 μM induction group cells at 28 days showed significantly higher levels of C-peptide and insulin secretion than the control, 5 μM, 500 μM, and 5 mM GABA-treated groups (P < 0.01). At the same time, the 50 μM induction group cells also showed significantly higher levels of Ins1, Pdx1 and Nkx6.1 mRNA as compared to the 5 μM, 500 μM and 5 mM GABA groups (P < 0.01). Thus, the addition of GABA to the basal medium effectively induced differentiation of adult rat PDESCs into insulin-secreting β-like cells, and 50 μM was the most effective concentration for the induction.

Abstract
Objective In this study we investigated the effect of dorsomedial hypothalamus (DMH) neuropeptide Y (NPY) knock-down on hepatic insulin sensitivity in high-fat (HF) diet-fed rats. Methods Forty-eight Sprague-Dawley rats were randomly assigned to receive bilateral DMH injections of adeno-associated virus AAVshNPY or AAVshCTL and then accessed to regular chow. Five weeks after viral injection, half rats in each group were given access to the HF diet. At 16 weeks, rat livers were collected. Insulin receptor substrate-1 (IRS-1) and phosphoinositide 3-kinase (PI3K) mRNA expression was measured by qRT-PCR. Blood glucose levels were measured by the oxidase method, serum insulin, triglyceride, and TC levels were measured by Elisa. Pathological changes in the liver were assessed by hematoxylin-eosin (HE) staining. AKT, p-AKT, and GSK-3 levels were measured by western blotting. Results Compared with AAVshCTL-injected rats, AAVshNPY-injected rats showed a significant decrease in blood glucose concentrations; serum insulin, triglyceride, and TC; HOMA-IR; and IRS-1 and PI3K mRNA levels (P<0.05). ISI, GSK-3, and p-AKT levels were significantly increased (P<0.05). HE staining showed that AAVshNPY-injected rats fed the HF diet had mild fatty degeneration. Conclusion These results suggest that DMH NPY knock-down improves hepatic insulin sensitivity in HF diet-fed rats by activating the hepatic PI3K/AKT insulin signalling pathway.

This study was designed to evaluate the effects of probiotic Bacillus amyloliquefaciens SC06 (Ba), originally isolated from soil, in piglets diet as an alternative to antibiotics (aureomycin), mainly on intestinal epithelial barrier and immune function. Ninety piglets were divided into three groups: G1 (containing 150 mg/kg aureomycin in the diet); G2 (containing 75 mg/kg aureomycin and 1×108 cfu/kg Ba in the diet); G3 (containing 2×108 cfu/kg Ba in the diet without any antibiotics). The results showed that, compared with the antibiotic group (G1), villus length, crypt depth and villus length/crypt depth ratio of intestine significantly increased in the G2 and G3 groups. In addition, intestinal villi morphology, goblet-cell number, mitochondria structure and tight junction proteins of intestinal epithelial cells in G2 and G3 were better than in G1. The relative gene expression of intestinal mucosal defensin-1, claudin3, claudin4, and human mucin-1 in G3 was significantly lower, while the expression of villin was significantly higher than in the antibiotic group. Probiotic Ba could significantly decrease serum interferon (IFN)-α, IFN-γ, interleukin (IL)-1β, and IL-4 levels, whereas increase tumour necrosis factor (TNF)-α and IL-6 secretion. Ba could also significantly decrease cytokines TNF-α, IFN-γ, IL-1β, and IL-4 level in liver, whereas it significantly increased IFN-α. Furthermore, replacing antibiotics with Ba also significantly down-regulated gene expression of TNF and IL-1α in intestinal mucosa, but up-regulated IL-6 and IL-8 transcription. Dietary addition of Ba could significantly reduce the gene expression of nuclear factor kappa beta (NFκB)-p50 and Toll-like receptor (TLR)6, while there was no significant difference for that of myeloid differentiation primary response 88, TNF receptor-associated factor-6, nucleotide-binding oligomerisation domain-containing protein 1, TLR2, TLR4, and TLR9. Taken together, our findings demonstrated that probiotic Ba could increase the intestinal epithelial cell barrier and immune function by improving intestinal mucosa structure, tight junctions and by activating the TLRs signalling pathway.

Abstract
Objective: To investigate the association between kinase insertion region receptor (KDR) gene genetic variation and the efficacy of bevacizumab in patients with advanced colorectal cancer(CRC) were investigated in this study. Methods: 118 patients with advanced colorectal cancer who were treated by bevacizumab based first line regimens were included in this study. Peripheral blood and the biopsy tissue specimens of the CRC patients were collected for the genotyping of genetic variation and KDR gene expression, respectively. The univariate analysis of genotypes and prognosis was carried out by Kaplan-Meier survival analysis, and multivariate were adjusted by Cox regression analysis. Results: Located in the coding region, the prevalence of 889 C>T in KDR among the study population were as follows: CC genotype 86 cases (72.88%), CT genotype 30 cases (25.42%), TT genotype 2 cases (1.70%), minor allele frequency of 889 C>T is 0.14. The distribution of three genotypes in accordance with Hardy-Weinberg Equilibrium (P=0.737). There were no statistical differences in the distribution of the genotypes in baseline clinical data. TT and CT genotype patients were merged in the comparison of clinical outcomes. The clinical outcomes analysis of patients with different genotypes found that the objective response rates (ORR) of CT/TT genotypes were 34.38% and 43.02% (P=0.395), respectively. And the median progression free survival (PFS) of patients with CT/TT genotype and CC genotype were 7.5 and 9.7 months respectively, which was statistically significant (P=0.009). In terms of overall survival (OS), the median OS of the two genotypes were 19.3 and 20.1 (P=0.025), respectively. Adjusted in multivariate Cox regression analysis of PFS, CT/TT genotypes were an independent factor for PFS (OR=1.88, P=0.023). Additionally, of the 57 biopsy tissue specimens, gene expression analysis was conducted. And the results showed that the expression of KDR in cancer tissues of the patients with CT/TT genotypes were significantly higher than those of the CC genotype patients (P<0.001). Conclusion: Among advanced colorectal cancer patients treated by bevacizumab, the polymorphism 889 C>T of KDR may impact the clinical outcomes of bevacizumab first line treatment by influencing the mRNA expression of KDR.

Abstract
Background Although the significance of D-dimer in cancer patients has been extensively studied and plasma D-dimer levels have been reported to be abnormally high in certain types of lung cancer patients, its prognostic value for small cell lung cancer (SCLC) remains largely unknown. Methods One hundred and seven newly diagnosed SCLC patients were enrolled in this study. Variables including the clinical features, pre-treatment levels of D-dimer, serum neuron-specific enolase (NSE), and carcinoembryonic antigen (CEA) were extracted. The correlations between D-dimer levels and prognosis of the patient were analysed with Kaplan-Meier survival analysis. Results Plasma D-dimer levels were elevated in 57.01% of patients. Patients with extensive stage disease had higher D-dimer levels compared with those at limited stage. D-dimer levels were positively correlated with NSE and CEA levels. The elevated D-dimer levels were significantly associated with the SCLC-related mortality. Patients with elevated D-dimer levels had a shorter median survival time than those with normal levels, and a significant difference existed between the two groups. Conclusions Increased D-dimer levels suggested a shorter survival time in SCLC patients. Pre-treatment D-dimer level is useful in estimating the prognosis of patients with SCLC.
