Prevalence and management of pain in lung cancer patients in northern China: A multicenter cross-sectional study. Thorac Cancer 2022; 13:1684-1690. [PMID: 35579111 PMCID: PMC9161334 DOI: 10.1111/1759-7714.14444] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2021] [Revised: 04/13/2022] [Accepted: 04/13/2022] [Indexed: 12/03/2022] Open
Abstract
Background Pain is a fearful yet common symptom among lung cancer patients. This multicenter, cross‐sectional study was conducted to examine the current status of pain prevalence and management in lung cancer patients in northern China. Methods A total of 18 hospitals across northern China were selected. Patients with primary lung cancer who visited the outpatient clinic or were admitted in the wards on a preplanned day were invited to complete a questionnaire. Meanwhile, physicians who had experience of treating primary lung cancer patients were also surveyed. Results A total of 533 patients and 197 physicians provided valid responses to the survey, of which 45.4% (242/533) of patients reported pain during the course of disease and 24.2% (129/533) of patients had experienced pain within the past 24 h. The mean average pain intensity by the brief pain inventory was 3.47 ± 1.55. The binary logistic regression analysis showed female gender and stage IV disease were significantly associated with the presence of pain. A total of 74.4% (96/129) of patients reporting pain within 24 h were taking analgesics. The most common reason for patients not using analgesics was that the pain was tolerable (48.2%), while the most common barriers to prescribing opioids as reported by physicians were fear of adverse reactions (43.7%) and fear of addiction (43.1%). Conclusion Despite recognition of the importance of pain control by most physicians and an improvement in cancer pain management, inadequate treatment of cancer pain still exists in lung cancer patients in northern China. High‐quality pain education for both patients and physicians is needed in the future.

Efficacy of different sequential patterns after crizotinib progression in advanced anaplastic lymphoma kinase-positive non-small cell lung cancer. Thorac Cancer 2022; 13:1788-1794. [PMID: 35560808 PMCID: PMC9200878 DOI: 10.1111/1759-7714.14455] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2022] [Revised: 04/19/2022] [Accepted: 04/20/2022] [Indexed: 11/29/2022] Open
Abstract
Background The efficacy difference between the second‐ and third‐generation of anaplastic lymphoma kinase‐tyrosine kinase inhibitors (ALK‐TKIs) after crizotinib failure in advanced ALK‐positive non–small cell lung cancer (NSCLC) has not been clarified. This study evaluates the efficacy of different sequential patterns after crizotinib progression. Methods Data of patients who met the study criteria were retrospectively analyzed. The Kaplan–Meier method was used to draw survival curves, log‐rank method was used to compare the differences between groups, and Cox multivariate analysis was used to evaluate the significance of influencing factors. Results A total of 128 patients developed disease progression after crizotinib. The overall survival (OS) of 57 patients in the sequential second‐generation ALK‐TKIs group was significantly longer than that of 65 patients with other systemic treatment (58.5 months vs. 33.0 months, p < 0.001); The OS of the direct sequential lorlatinib group was significantly longer than the second‐generation ALK‐TKIs group (114.0 months vs. 58.5 months, p = 0.020). Similarly, of the 48 patients who developed disease progression after first‐ and second‐generation ALK‐TKIs treatment, 16 patients with sequential lorlatinib had significantly longer OS than the others (62.0 months vs. 43.0 months, p = 0.014). The progression‐free survival (PFS) of second‐line and third‐ or later‐line lorlatinib were statistically different (20.0 months vs. 5.5 months, p = 0.011). Conclusions The application of next‐generation ALK‐TKIs after crizotinib progression significantly prolonged survival, whereas direct sequencing lorlatinib seemed advantageous. Similarly, lorlatinib also prolonged survival in patients with first‐ and second‐generation ALK‐TKIs failure.

Abstract
Aims Our team tested spinal cord fusion (SCF) using the neuroprotective agent polyethylene glycol (PEG) in different animal (mice, rats, and beagles) models with complete spinal cord transection. To further explore the application of SCF for the treatment of paraplegic patients, we developed a new clinical procedure for SCF called vascular pedicle hemisected spinal cord transplantation (vSCT) and tested this procedure in eight paraplegic participants. Methods Eight paraplegic participants (American Spinal Injury Association, ASIA: A) were enrolled and treated with vSCT (PEG was applied to the sites of spinal cord transplantation). Pre‐ and postoperative pain intensities, neurologic assessments, electrophysiologic monitoring, and neuroimaging examinations were recorded. Results Of the eight paraplegic participants who completed vSCT, objective improvements occurred in motor function for one participant, in electrophysiologic motor‐evoked potentials for another participant, in re‐establishment of white matter continuity in three participants, in autonomic nerve function in seven participants, and in symptoms of cord central pain for seven participants. Conclusions The postoperative recovery of paraplegic participants demonstrated the clinical feasibility and efficacy of vSCT in re‐establishing the continuity of spinal nerve fibers. vSCT could provide the anatomic, morphologic, and histologic foundations to potentially restore the motor, sensory, and autonomic nervous functions in paraplegic patients. More future clinical trials are warranted.

Abstract
Dispersion impairments are a well-known limitation in data center communications, limiting both the usable data rates and reaches. Several companies today adopt silicon photonics as a core technology in their transceiver products. This presents an opportunity for silicon photonics-based dispersion management technologies to be integrated with the transceiver transmitter or receiver. In this manuscript, we present a ring-resonator based, tunable dispersion compensation device, providing dispersion ranging as wide from + 12.9 × 103ps/nm to -12.3 × 103ps/nm. Thermo-optic tuning from 20°C to 70°C is demonstrated to allow continuous wavelength tuning across 200 GHz. High-speed experiments using 25 Gb/s non-return-to-zero data propagating through 20 km of single mode fiber show that a significant improvement in the eye diagram is achieved after compensation with the ring-resonator device. We demonstrate a significant improvement in the BER from 10-3 to 10-11 for data rates of 25 and 25.78125 Gb/s.

Abstract
PURPOSE Erectile dysfunction and COVID-19 share similar risk factors, including vascular disruption of integrity, cytokine release, cardiovascular disease, diabetes and obesity. The aim of this study was to investigate the association between erectile dysfunction and COVID-19 patients. METHODS Odds ratio for erectile dysfunction in patients with a history of COVID-19 with and without comorbidities were calculated using a patients' registry platform i2b2. ICD-10 diagnoses codes were accessed for queries and data were analyzed using logistic regression. RESULTS Patients with COVID-19 were 3.3 times more likely to have erectile dysfunction with 95% CI (2.8, 3.8). The association became stronger with odds ratio 4.8 (95% CI (4.1, 5.7)) after adjusting for age groups. The odds ratio remained the same after adjusting for smoking status with 3.5 (95% CI (3.0, 4.1)). After adjusting for race, COVID-19 patients were 2.6 (95% CI (2.2, 3.1)) times more likely to have erectile dysfunction. The odds ratio were 1.6, 1.8, 1.9 and 2.3 after adjusting for respiratory disease, obesity, circulatory disease and diabetes, respectively. CONCLUSION COVID-19 and erectile dysfunction are strongly associated even after adjustment for known risk factors and demographics.

Abstract
Differential cross sections for Compton scattering from the proton have been measured at scattering angles of 55°, 90°, and 125° in the laboratory frame using quasimonoenergetic linearly (circularly) polarized photon beams with a weighted mean energy value of 83.4 MeV (81.3 MeV). These measurements were performed at the High Intensity Gamma-Ray Source facility at the Triangle Universities Nuclear Laboratory. The results are compared to previous measurements and are interpreted in the chiral effective field theory framework to extract the electromagnetic dipole polarizabilities of the proton, which gives α_{E1}^{p}=13.8±1.2_{stat}±0.1_{BSR}±0.3_{theo},β_{M1}^{p}=0.2∓1.2_{stat}±0.1_{BSR}∓0.3_{theo} in units of 10^{-4} fm^{3}.

Abstract
In this paper, we study a SEIRS model with Neumann boundary condition for a population distributed in a spatial grid. We first discuss the existence and uniqueness of global positive solution with any given positive initial value. Next, we introduce the basic reproduction number of this model. Then we consider the relation between the system of PDE and the discrete ODE model. Finally, we consider the stochastic model and give two laws of large numbers.

Abstract
The lunar nearside has been investigated by many uncrewed and crewed missions, but the farside of the Moon remains poorly known. Lunar farside exploration is challenging because maneuvering rovers with efficient locomotion in harsh extraterrestrial environment is necessary to explore geological characteristics of scientific interest. Chang'E-4 mission successfully targeted the Moon's farside and deployed a teleoperated rover (Yutu-2) to explore inside the Von Kármán crater, conveying rich information regarding regolith, craters, and rocks. Here, we report mobile exploration on the lunar farside with Yutu-2 over the initial 2 years. During its journey, Yutu-2 has experienced varying degrees of mild slip and skid, indicating that the terrain is relatively flat at large scales but scattered with local gentle slopes. Cloddy soil sticking on its wheels implies a greater cohesion of the lunar soil than encountered at other lunar landing sites. Further identification results indicate that the regolith resembles dry sand and sandy loam on Earth in bearing properties, demonstrating greater bearing strength than that identified during the Apollo missions. In sharp contrast to the sparsity of rocks along the traverse route, small fresh craters with unilateral moldable ejecta are abundant, and some of them contain high-reflectance materials at the bottom, suggestive of secondary impact events. These findings hint at notable differences in the surface geology between the lunar farside and nearside. Experience gained with Yutu-2 improves the understanding of the farside of the Moon, which, in return, may lead to locomotion with improved efficiency and larger range.

Abstract
We studied the effects of Huaier polysaccharide (HP) in doxorubicin-induced myocardial injury in mice. The content of HP in Trametes robiniophila Murr medicinal fungus determined by the phenol-sulfuric acid method was 85.25%. In the in vitro model, the viability of H9c2 cells was significantly increased after HP treatment compared to the control, while doxorubicin (DOX) decreased this parameter. The inhibitory effect of DOX on cell viability was attenuated after HP treatment. In the in vivo model, the body weight of mice in DOX and DOX+HP groups was significantly decreased compared to the control group. ECG showed significantly elevated ST segment in the DOX group, while in the DOX+HP group, ECG was close to normal. The levels of cardiotoxicity markers cTnI and lactate dehydrogenase in the DOX+HP group were significantly lower than in the DOX group. In the DOX group, the myocardial tissue had obvious structural disorder and interfibrillar vacuoles. In the DOX+HP group, the cardiomyocytes were neatly arranged without interfibrillar vacuoles. The expression of the ferroptosis marker glutathione peroxidase 4 was increased in the DOX+HP group compared to the DOX group. Thus, our study reveals that HP attenuated DOX-induced myocardial injury in mice probably by regulating ferroptosis.

Abstract
OBJECTIVE Cyclin-dependent kinase 4/6 inhibitors (CDK4/6i) in combination with endocrine therapy (ET) have been recommended as standard therapeutic strategies for hormone receptor-positive (HR+), human epidermal growth factor receptor type 2-negative (Her2-) advanced breast cancer (ABC). While the benefits to progression-free survival (PFS) rates have been confirmed, whether the combination of CDK4/6i and ET leads to overall survival (OS) rate improvements remains controversial. This study aimed to assess the long-term efficacy and safety of CDK4/6i in HR+, Her2- ABC patients and identify a population suitable for treatment with CDK4/6i by subgroup analysis. MATERIALS AND METHODS Electronic literature databases (MEDLINE, EMBASE and the Cochrane Library) were searched for relevant randomized controlled trials (rcts) published from Jan 2014 to Jan 2020. In addition, abstracts and presentations from all major conference proceedings were reviewed. All rcts that compared the efficacy and safety of CDK4/6i plus ET with ET alone in HR+, Her2- ABC patients were selected. The pooled analyses of hazard ratios (hrs) for PFS and OS, and risk ratios (rrs) for the objective response rate (ORR) and adverse events (aes) were obtained with the random-effects model. RESULTS A total of 6 rcts and 3421 HR+, Her2- ABC patients were enrolled for OS outcome analysis, while all 8 trials and 4580 patients were included for PFS outcome analysis. The pooled hrs for the OS and PFS were 0.76 (95% CI: 0.67-0.84) and 0.55 (95% CI: 0.50-0.59), respectively, and were consistent in the subgroup analysis. Moreover, CDK4/6i meaningfully improved the ORR in both the intention-to-treat population (RR=1.47; 95% CI: 1.29-1.67) and patients with measurable disease (RR=1.47; 95% CI: 1.30-1.67); however, CDK4/6i increased the incidence of grade 3/4 aes (RR=2.69; 95% CI: 2.43-2.97). CONCLUSIONS The combination of CDK4/6i and ET was superior to ET alone in terms of OS and PFS regardless of the drugs administered, the treatment line, age distribution, race, PR status, menopausal status, metastasis site and endocrine resistance status.

Abstract
BACKGROUND We compared the efficacy, safety, and immunogenicity of MIL60 with reference bevacizumab as first-line treatment in patients with advanced or recurrent non-squamous non-small cell lung cancer (NSCLC) in this phase 3, randomized, double-blind study. METHODS Patients with untreated advanced or recurrent NSCLC were randomized (1:1 ratio) to receive either MIL60 or bevacizumab in combination with paclitaxel/carboplatin. Patients with non-progressive disease continued maintenance single-agent MIL60 until disease progression, or intolerable toxicity. The primary endpoint was the 12-week objective response rates (ORR12) by independent review committee (IRC) using RECIST 1.1. Bioequivalence was established if the ORR ratio located between 0.75 and 1/0.75. The trial was registered with clinicaltrials.gov (NCT03196986). FINDINGS Between Aug 23, 2017, and May 8, 2019, 517 patients were randomly assigned to MIL60 group (n=257) and bevacizumab group (n=260). In the full analysis set (FAS) population including all randomized and evaluable patients who received at least one dose of MIL60 or bevacizumab, the ORR12 in MIL60 group and bevacizumab group were 48.6% and 43.1%, respectively. The ORR ratio of these two groups were 1.14 (90% CI 0.97-1.33), which fell within the pre-specified equivalence boundaries (0.75-1/0.75). The median DOR was 5.7 months (95% CI 4.5-6.2) for MIL60 and 5.6 months (95% CI 4.3-6.4) for bevacizumab. No significant difference was noted in median PFS (7.2 vs. 8.1 months; HR 1.01, 95% CI 0.78-1.30, p=0.9606) and OS (19.3 vs. 16.3 months; HR 0.81, 95% CI 0.64-1.02, p=0.0755). Safety and tolerability profiles were similar between the two groups. No patient detected positive for Anti-drug antibody (ADA). INTERPRETATION The efficacy, safety and immunogenicity of MIL60 were similar with bevacizumab, providing an alternative treatment option for advanced or recurrent non-squamous NSCLC.

Abstract
Objective: To investigate the clinical effect of applying hydrogel dressings in deep partial-thickness burn wounds after dermabrasion and tangential excision. Methods: A prospective randomized controlled study was conducted. From November 2015 to August 2019, 168 patients with deep partial-thickness burns hospitalized in Zibo Sixth People's Hospital met the inclusion criteria. According to the random number table, the patients were divided into hydrogel dressing+vaseline gauze group (84 cases, 67 males and 17 females) and vaseline gauze only group (84 cases, 65 males and 19 females) who were aged (31±16) and (35±17) years, respectively, and were given corresponding treatment after dermabrasion and tangential excision. The dressings were changed every 3-5 days. Autologous skin grafting was performed with split-thickness or medium-thickness skin grafts taken from trunk or thigh if the wounds failed to heal over 21 days or the wounds were less than 21 days but located in the joints, which might affect the functional activities at later stage. After operation, the general condition of the wounds was observed continuously and dynamically till the wounds were healed. The degree of dressing adhesion was evaluated during the first 4 dressing changes after operation, and the degree of pain was evaluated using Numerical Rating Scale (NRS). The wound healing rate on post operation day (POD) 3, 6, and 15 was calculated. The positive proportion of bacterial culture of wound exudates/cleanout fluid on admission and at dressing change on POD 3, 6, and 15 was calculated. The number of dressing changes were recorded, the rate of skin grafting operation was calculated, and the time of complete wound healing was recorded. Vancouver Scar Scale (VSS) was used in 6 months of follow-up to evaluate the hyperplasia of scar. Data were statistically analyzed with analysis of variance for repeated measurement, independent sample t test, Mann-Whitney U test, chi-square test or Fisher's exact probability test, and Bonferroni correction. Results: During the observation period after operation, the wound was moist with less exudates and the wound healed much faster in patients of hydrogel dressing+vaseline gauze group, with the inner dressing being easier to remove with mild pain, while the wounds showed more exudates and slower healing in patients of vaseline gauze only group with the obvious adhesions of inner dressing, stronger pain, and bleeding in the wounds. Compared with those in vaseline gauze only group, the degree of dressing adhesion and pain NRS score of patients in hydrogel dressing+vaseline gauze group decreased significantly during the first 4 dressing changes after operation (χ2=52.625, Z=-10.854, P<0.01), the wound healing rate increased significantly at dressing change on POD 3, 6, and 15 (t=10.347, 41.150, 167.627, P<0.01), the positive proportion of wound exudates/cleanout fluid bacterial culture did not change significantly on admission or at dressing change on POD 3 (P>0.05) but decreased significantly at dressing change on POD 6 and 15 (χ2=15.616, 15.226, P<0.01), the dressing change times was significantly reduced (t=-11.986, P<0.01), and the rate of skin grafting operation was significantly decreased (χ2=35.850, P<0.01). The complete wound healing time of patients in hydrogel dressing+vaseline gauze group was (17.6±2.8) d, significantly shorter than (27.1±3.0) d in vaseline gauze only group (t=-21.288, P<0.01). During the follow-up of 6 months, the VSS score of scar hyperplasia of patients in hydrogel dressing+vaseline gauze group was significantly lower than that in vaseline gauze only group (Z=-11.287, P<0.01). Conclusions: Compared with the use of vaseline gauze only, the application of vaseline gauze coated with hydrogel dressing in deep partial-thickness burn wounds after dermabrasion and tangential excision is more effective in moisturizing, significantly reducing the degree of dressing adhesion and patients' pain during dressing change, increasing wound healing rate, decreasing wound infection rate and the rate of skin grafting operation, and reducing the number of dressing changes. It shortens the time for complete wound healing, and effectively relieves scar hyperplasia.

Abstract
Introduction Pembrolizumab plus chemotherapy significantly improved survival outcomes versus placebo plus chemotherapy in patients with previously untreated metastatic squamous NSCLC in the randomized, double-blind, phase 3 KEYNOTE-407 study. We present the results of Chinese patients enrolled in the KEYNOTE-407 global and China extension studies. Methods Patients enrolled from mainland China in the KEYNOTE-407 global (NCT02775435) and China extension studies (NCT03875092) were randomized 1:1 to 35 cycles of pembrolizumab or placebo plus four cycles of carboplatin and paclitaxel or nab-paclitaxel. Dual primary end points were overall survival (OS) and progression-free survival (PFS) (based on the Response Evaluation Criteria in Solid Tumors version 1.1 by blinded independent central review). Results A total of 125 patients were randomized (pembrolizumab-chemotherapy, n = 65; placebo-chemotherapy, n = 60). As of September 30, 2020, median (range) study follow-up was 28.1 (25.1‒40.9) months. Pembrolizumab-chemotherapy improved OS (hazard ratio [HR] = 0.44, 95% confidence interval [CI]: 0.28-0.70) and PFS (HR = 0.35, 95% CI: 0.24-0.52) versus placebo-chemotherapy. Two-year OS and PFS rates for pembrolizumab-chemotherapy versus placebo-chemotherapy were 56.9% versus 31.7% and 24.2% versus 3.3%, respectively. Treatment-related grade 3 to 5 adverse events occurred in 81.5% and 81.7%, respectively. Relative to baseline, pembrolizumab-chemotherapy improved global health status/quality of life scores at week 18 versus placebo-chemotherapy (difference in least squares means = 7.6, 95% CI: 1.5-13.7) and prolonged time to deterioration in cough, chest pain, or dyspnea (HR = 0.50, 95% CI: 0.28-0.89). Conclusions Pembrolizumab-chemotherapy prolonged survival versus placebo-chemotherapy with manageable toxicity and preserved or improved health-related quality of life in Chinese patients with metastatic squamous NSCLC. These findings support pembrolizumab-chemotherapy as first-line therapy in this population.

Abstract
Objective: To analyze the clinical value and predictive difference of serum Golgi protein 73 (GP73) and serum autophagy-related protein p62 levels in the short-term prognosis of patients with hepatitis B virus-related acute-on-chronic liver failure (ACLF). Methods: Clinical data of admitted cases to our hospital from October 2018 to April 2020 were retrospectively analyzed. Simultaneously, there were 32 cases with HBV-related ACLF in group A, 65 cases with hepatitis B virus-related cirrhosis in group B and C (Child-Pugh Class A, 34 cases as B group, and Child-Pugh B/C class, 31 cases as group C), and another 30 healthy subjects served as the control group (group D). The serum GP73 and p62 levels of the four selected groups were measured. ACLF group patients were followed up for 3 months to analyze the prognosis of the patients. The serum GP73 and p62 levels of patients who died and survived during hospitalization were compared. The data were analyzed by one-way analysis of variance, independent sample t-test, and Pearson's correlation analysis. Receiver operating characteristic curve (ROC) was used to analyze the predictive value of GP73 and p62 levels in surviving patients. Results: GP73 levels in the four groups A, B, C and D were (284.30 ± 70.55) ng/ml, (125.33 ± 20.57) ng/ml, (159.82 ± 31.20) ng/ml, and (45.46 ± 10.22) ng/ml, respectively. The p62 levels were (1.30 ± 0.35) ng/ml, (2.88 ± 0.58) ng/ml, (2.02 ± 0.545) ng/ml, and (4.68 ± 1.03) ng/ml, respectively. GP73 detection value was significantly higher in group A than the other three groups (P < 0.05). Group D had significantly lower value than the other three groups (P < 0.05), and group C had significantly higher value than group B (P < 0.05). The detection value of p62 in group A was significantly lower than the other three groups (P < 0.05). Group D had significantly higher value than the other three groups (P < 0.05), and group B had slightly higher value than group C, and the differences were statistically significant (P < 0.05). There was a negative correlation between GP73 and p62 (r = -0.695, P < 0.001). Survived patients GP73 level in the ACLF group was significantly lower than dead patients [(212.17 ± 22.47) ng/ml and (340.08 ± 32.91) ng/ml, t = 12.493, P < 0.05], and p62 level was significantly higher than dead patients [(1.46 ± 0.28) ng/ml and (1.18 ± 0.35) ng/ml, t = 2.445, P < 0.05]. According to the ROC curve analysis results, the area under the curve (AUC) of GP73 was 0.865, the AUC of p62 was 0.750, and the combined AUC of the both was 0.968. Conclusion: Both GP73 and p62 have a certain predictive value for the short-term prognosis of HBV-related ACLF patients, but the combination of the two indicators has a higher predictive value.

Abstract
Background detection of anaplastic lymphoma receptor tyrosine kinase gene (ALK) rearrangements in patients with non‐small‐cell lung cancer (NSCLC) has become a routine pathological diagnosis worldwide. Methods there are three major conventional diagnostic methods for ALK fusions: fluorescent in situ hybridization (FISH); immunohistochemistry (Ventana IHC (D5F3)); and polymerase chain reaction (PCR). Next‐generation sequencing (NGS) technology as is a new tool for ALK status detection with great potential. These four methods are highly consistent in detecting ALK status (coincidence rate >96%). However, discrepancies in ALK status have been found in some patients among these methods, which causes confusion for clinicians. Results and conclusion in this study, we analyzed two patients whose ALK statuses were not consistent using these four methods. We explored the potential reasons for deviation of the test results and found a novel EML4‐ALK break site, which had been not described previously.

Abstract
OBJECTIVE To explore the effect of melatonin (MT) on 2, 2', 4, 4'-tetrabromodiphenylether (PBDE-47)-induced abnormal autophagy and apoptosis in rat adrenal medullary pheochromocytoma PC12 cells. METHODS PC12 cells were pretreated with a concentration gradient (12.5, 25, 50, 100, and 200 μmol/L) of melatonin for 2 h before exposure to 20 μmol/L PBDE-47 for 24 h to determine the optimal concentration of melatonin for cell treatment. In subsequent experiments, PC12 cells were treated with 0.5‰ DMSO (control group), 20 μmol/L PBDE-47, 25 μmol/L melatonin, or both PBDE-47 and melatonin. Immunofluorescence assay was used to detect the positive staining of microtubule associated protein 1 light chain 3 (LC3; a marker protein of autophagy); Western blotting was performed to determine the expression levels of the key autophagic proteins including autophagy-related protein 7 (ATG7), LC3-Ⅱ and autophagy substrate p62, and the key apoptotic proteins including active cysteine-containing aspartate specific protease-3 (active caspase-3) and cleaved poly(ADP ribose) polymerase (cleaved PARP). RESULTS PBDE-47 treatment significantly reduced the viability of PC12 cells (P=0.001), but pretreatment with 25 μmol/L melatonin maintained a cell viability over 80% following exposure to PBDE-47 (P=0.023). PBDE-47-treated PC12 cells showed obviously enhanced immunofluorescent staining of LC3 protein, a significantly decreased expression of ATG7 and increased expression levels of p62, LC3-Ⅱ, active caspase-3 and cleaved PARP (P < 0.001). The cells treated with both PBDE-47 and melatonin showed obviously reduced staining of LC3 protein with a signficantly increased expression level of ATG7 (P=0.034) and decreased expressions of p62 (P=0.048), LC3-Ⅱ (P=0.018), active caspase-3 (P < 0.001) and cleaved PARP (P=0.032). CONCLUSION PBDE-47 exposure impairs autophagy to cause autophagosome accumulation and promote apoptosis of PC12 cells. Melatonin can improve PBDE-47-induced abnormal autophagy and apoptosis and thus promote the survival of PC12 cells.

Abstract
AIMS This study investigated the dose-effect of manganese (Mn) addition on wheat straw (WS) decomposition, and explored the potential mechanisms of Mn involved in the acceleration of WS decomposition in regards to the soil microbial communities and enzyme activities. METHODS AND RESULTS A 180-day incubation experiment was performed to examine the decomposition of WS under four Mn levels, that is, 0, 0.25, 1 and 2 mg g-1 . The effects of microbial communities and enzyme activities were evaluated using control (0 mg g-1 ) and Mn (0.25 mg g-1 ) treatments. Our results revealed that Mn (0.25 mg g-1 ) addition significantly increased WS decomposition, and enhanced the release of carbon and nitrogen. Optimal Mn addition (0.25 mg g-1 ) also caused significant increases in the activity of neutral xylanase (NEX), laccase (Lac), manganese peroxidase (MnP) and lignin peroxidase (LiP) within the incubation period. Mn (0.25 mg g-1 ) addition also enriched some operational taxonomic units (OTUs) that, in turn, had the potential ability to decompose crop straw, such as secreting lignocellulolytic enzymes. CONCLUSIONS Mn (0.25 mg g-1 ) could promote WS decomposition through enrichment of the microbial species involved in biomass decomposition, which enhanced the lignocellulose-degrading enzyme activity. SIGNIFICANCE AND IMPACT OF THE STUDY This study provides evidence for Mn to promote WS biodegradation after Mn application, opening new windows to improve the utilization efficiency of crop residues.

Abstract
Objective: To analyze the clinical features and evaluate the prognoses of Pythium keratitis. Methods: It was a retrospective study. The clinical characteristics, confocal microscopic image characteristics, treatment and curative effect of 6 cases of Pythium keratitis identified by DNA sequencing from June 2017 to June 2019 were reviewed retrospectively. Results: Among the 6 patients, there were 4 males and 2 females. All cases were monocular. The age was (58.7±11.3) years (range, 52 to 72 years). Keratopathy under a slit lamp was characterized by a dry ulcer surface, burr signs, satellite foci and pseudopodia around the ulcer. An elevated lesion was observed in 2 patients, and no obvious immune ring structure was observed in all patients. Confocal microscopy did not reveal any specific characteristics of Pythium infection. All patients did not respond well to antifungal drugs and received keratoplasty. Three patients had postoperative recurrence. The recurrence time was 4-6 days after the first operation and 2-3 days after the second operation. Two patients underwent two and three corneal transplants, respectively, after recurrence, but evisceration was required finally. Conclusions: Pythium keratitis is rare and can hardly be distinguished from common fungal infections in clinical manifestations and auxiliary examinations. The disease progresses rapidly, the rates of recurrence and evisceration after keratoplasty are both high, and DNA sequencing is the key to identifying the etiology, which should be paid more attention.
