Abstract
Abstract
Aims
Heart Failure (HF) has a disproportionate burden in low- and middle-income countries. The geographic representation of those who lead HF randomized clinical trials (RCTs) may not reflect the geographic burden of disease. We assessed temporal trends and trial characteristics associated with leadership outside Europe and North America, and explored whether there was a geographic association between trial leadership and participant enrolment.
Methods and results
We searched MEDLINE, EMBASE, and CINAHL for HF RCTs published in journals with an impact factor ≥10 between January 1, 2000, and June 17, 2020. We used the Jonckheere-Terpstra test to assess temporal trends and multivariable logistic regression models to determine associations between predictor and outcome variables.
There were 414 eligible RCTs. Only 80 of 828 trial leaders (9.7%; 95% CI: 7.8% to 11.8%), and 453 of 4656 collaborators (9.7%; 95% CI: 8.8% to 10.6%) were from regions outside Europe and North America, with no temporal change in geographic representation. The odds of trial leadership outside Europe and North America were significantly lower with industry versus public funding (OR: 0.33; 95% CI: 0.15 to 0.75; P=0.008). Trial leadership outside Europe and North America was associated with enrolment of patients outside Europe and North America (OR: 10.0; 95% CI 5.6–19.0; P<0.001).
Conclusion
Trial leadership outside Europe and North America is rare, particularly in industry funded trials, and is associated with participant enrolment in regions with disproportionate disease burden. Building research capacity and networks in under-represented regions could increase generalizability of trial results.

Abstract
Bovine parvovirus (BPV), bovine coronavirus (BCoV) and bovine parainfluenza virus (BPIV) are common etiologies causing gastrointestinal and respiratory diseases in dairy herds. However, there are few reports on the synchronous detection of BPV, BCoV and BPIV. The present article aimed to develop a quick and accurate RT-PCR assay to synchronously detect BPV, BCoV and BPIV based on their specific probes. One pair universal primers, one pair specific primers and one specific probe was designed and synthesized. After the concentrations of primer and probe and annealing temperature were strictly optimized, the specificity, sensitivity and repeatability of the established triplex probe qRT-PCR were evaluated, respectively. The results showed the recombinant plasmids of pMD18-T-BPV, pMD18-T-BCoV and pMD18-T-BPIV were 554bp, 699bp and 704bp, respectively. The optimal annealing temperature was set at 45.0°C for triplex qRT-PCR. The triplex probe qRT-PCR can only synchronously detect BPV, BCoV and BPIV. Detection sensitivities were 2.0×102, 2.0×102 and 2.0×101 copies/μL for BPV, BCoV and BPIV, being 1000-fold greater than that in the conventional PCR. Detection of clinical samples demonstrated that triplex probe qRT-PCR had a higher sensitivity and specificity. The intra-assay and inter-assay coefficient of variation were lower than 2.0%. Clinical specimens verified that the triplex qRT-PCR had a higher sensitivity and specificity than universal PCR. In conclusion, this triplex probe qRT-PCR could detect only BPV, BCoV and BPIV. Minimum detection limits were 2.0×102 copies/μL for BPV and BCoV, and 2.0×101 copies/μL for BPIV. The sensitivity of this triplex probe qRT-PCR was 1000-fold greater than that in the conventional PCR. The newly qRT-PCR could be used to monitor or differentially diagnose virus infection.

Abstract
BACKGROUND Renal cell carcinoma (RCC) is the most common type of kidney cancer, and accounts for approximately 3% of all malignancies. Metastatic RCC (mRCC) is not sensitive to traditional radiotherapy and chemotherapy, therefore targeted therapy has become an important treatment option. In this study, the second-line targeted drug everolimus (Afinitor), a mammalian target of rapamycin (mTOR) inhibitor, was investigated for its clinical efficacy and adverse events in mRCC after failure of first-line targeted therapy, such as sorafenib, sunitinib or pazopanib. METHODS A total of 21 patients with mRCC who had been treated with surgery or other therapies such as tyrosine kinase inhibitors (TKIs) were given oral everolimus (10 mg/day) until disease progression. Clinical efficacy was evaluated using the Response Evaluation Criteria in Solid Tumors (RECIST) 2 months after therapy, including complete response (CR), partial response (PR), stable disease (SD), and progressive disease (PD). The adverse events were observed, and timely treatment was provided. RESULTS Everolimus extended progression-free survival (PFS) in mRCC patients from 4 to 8 months (median 6.3 months). There were 3 patients with PR, 12 with SD, and 6 with PD, and the disease control rate (DCR) was 15/21 (71.4%). Common adverse events included stomatitis, rash, and pneumonitis. CONCLUSIONS This study provides further support that everolimus is still an important option in mRCC treatment after failure of first-line targeted therapy. However, clinical studies are still needed to further improve its therapeutic efficacy.

Abstract
Casestudy: Clear cell sarcoma (CCS), also known as malignant melanoma of soft parts, is a primary soft tissue neoplasm exhibiting evidence of melanocytic differentiation. It is an uncommon aggressive tumor that arises in tendons and aponeuroses of the distal extremities. Here, we report the first case of primary CCS of the breast.
The patient was a 43-year-old female who presented with a left breast mass and underwent surgical resection at an outside hospital. No history of melanoma or any other malignancies was reported. Grossly, it was described as a 2 x 1.5 x 1.5 cm, well-demarcated, white nodular mass. Microscopic examination showed a malignant neoplasm composed of short spindle cells with ill-defined, eosinophilic cytoplasm and ovoid nuclei with finely stippled chromatin and exhibiting moderate pleomorphism. The lesional cells were arranged in short interlacing fascicles with abundant collagen, with brisk mitotic activity (>15/10 HPF). The differential diagnosis included spindle cell carcinoma, myoepithelial carcinoma and melanocytic neoplasm. The tumor cells were immunoreactive for S-100 protein, SOX10, Mart-1, HMB45 and MiTF, but negative for multiple cytokeratins (including high and low molecular weight keratins), p63, EMA, CEA, Caldesmon, smooth muscle myosin, calponin, desmin, ERG, and CD31, thus confirming melanocytic origin. EWSR1 gene rearrangement was detected by fluorescence in situ hybridization analysis using break-apart probes. Overall, the histomorphology combined with the immunophenotype and cytogenetic characteristics, was most consistent with a CCS. To our knowledge, no primary CCS of the breast has been previously reported in the English language literature.

Abstract
OBJECTIVE Lung cancer is the leading cause of cancer death in the world and microRNAs (miRNA) have been found to be involved in the initiation and development of cancer by acting as potential oncogenes or tumor suppressor genes. PATIENTS AND METHODS In this study, we investigated the expression of miR-34b in non-small cell lung cancer (NSCLC) patients and discussed the molecular mechanism of miR-34b in the invasion and migration of A549 cells in vitro. RESULTS Our results showed that miR-34b was significantly down-regulated in primary cancer tissues when compared with the normal lung tissues. The over-expression of miR-34b inhibited migration and invasion, and promoted apoptosis of A549 lung cancer cells. Furthermore, Luciferase reporter assay validated YY1-associated factor 2 (YAF2) as a direct target of miR-34b and YAF2 expression was significantly increased in clinical NSCLC tissue samples. In addition, the over-expression of miR-34b inhibited YAF2, p-Jak2, p-STAT3 and MMP2 protein expression and promoted caspase 3 protein expression in cancer cells. CONCLUSIONS Our results suggest that miR-34b may inhibit migration and invasion of NSCLC cells by targeting YAF2. Thus, our findings provide new insight into the molecular mechanisms of lung cancer metastasis and miR-34b may serve as a potential target in the treatment of human lung cancer.

Abstract
BACKGROUND Basal cell carcinoma (BCC) is the most common form of skin carcinoma. AIM To investigate the function of key micro(mi)RNAs and to explore the potential molecular mechanisms involved in BCC. METHODS The microarray dataset GSE34535, which comprises seven BCC samples and seven control samples, was downloaded from the Gene Expression Omnibus database. Differentially expressed miRNAs (DE-miRNAs) were identified. We collected tissue samples from 20 patients with BCC and 20 healthy controls (HCs), to compare the miR-18a expression in their tissue samples. Expression of miR-18a in A431 and HaCaT cells was also assayed. Following this, we upregulated and downregulated miR-18a expression in A431 cells to examine the effects on cell proliferation, migration and apoptosis. To further investigate the relative mechanism, the proteins LC3, Beclin 1, Akt and mammalian target of rapamycin (mTOR) were examined by quantitative real-time PCR and Western blotting. For further verification, we examined the expression of LC3 in the 20 BCC and 20 HC tissue samples. RESULTS In total, 19 DE-miRNAs (13 upregulated and 6 downregulated) that were common to the BCC and HC groups were identified. Levels of miR-18a were about three-fold higher in BCC tissues and A431 cells compared with their respective control groups. In vitro, downregulation of miR-18a was shown to inhibit cell proliferation and activate autophagy via the Akt/mTOR signalling pathway, while upregulation of miR-18a promoted proliferation of these cells. LC3 was decreased in BCC compared with HC tissue samples. CONCLUSIONS Our data support an oncogenic role of miR-18a through a novel Akt/mTOR/Beclin 1/LC3 axis, and suggest that the antitumour effects of miR-18a inhibitor may make it suitable for BCC therapy.

Abstract
Objective: To investigate the efficacy and safety of emergency venous sinus stenting in the treatment of acute visual impairment caused by idiopathic intracranial hypertension (IIH). Methods: A descriptive cross-sectional study design was used to retrospectively analyze 38 patients undergoing venous sinus stenting in the First Affiliated Hospital of Zhengzhou University from January 2013 to October 2019. A total of 9 patients who had sudden short-term vision loss met the inclusion criteria. Routine visual field and fundus examination were performed. The venous sinus stenosis (CVSS) was confirmed by MR venography or DSA. The pressure gradient at both ends of CVSS was ≥10 mmHg(1 mmHg=0.133 kPa). All patients were treated with emergency venous sinus stenting. Six-month follow-up data were collected for comparison, evaluation of the therapeutic effect, and observation of adverse reactions. Results: All 9 patients were successfully treated with venous sinus stent. The pressure gradient at the distal and proximal ends of the stenosis after stent implantation decreased to (2.3±1.2) mmHg. After 6 months of follow-up, the papilledema was significantly improved or disappeared in all patients. The average grade of papilledema decreased from 2.44±0.73 before operation to 0.56±0.53 after treatment (t=6.314, P<0.001). The visual acuity of 9 patients recovered to the pre-onset level or improved significantly after 6 months. The average baseline value of preoperative visual acuity (logMAR) was 0.12±0.11, which increased to 0.74±0.13 on average 6 months after operation (t=-10.827, P<0.001). No recurrence of symptoms or serious adverse reactions occurred in all patients during the follow-up period. Conclusion: For patients with acute visual impairment caused by idiopathic cranial hypertension, emergency venous sinus stenting is a relatively safe and effective treatment that can effectively improve visual acuity.

Abstract
Artesunate (ARS) has been shown to be highly effective against chloroquine-resistant malaria. In vitro studies reported that ARS has anticancer effects; however, its detrimental action on cancer cells may also play a role in its toxicity toward normal cells and its potential toxicity has not been sufficiently researched. In this study, we investigated the possible cytotoxic effects using normal BRL-3A and AML12 liver cells. The results showed that ARS dose-dependently inhibited cell proliferation and arrested the G0/G1 phase cell cycle in both BRL-3A and AML12 liver cells. Western blotting demonstrated that ARS induced a significant downregulation of cyclin-dependent kinase-2 (CDK2), CDK4, cyclin D1, and cyclin E1 in various levels and then caused apoptosis when the Bcl-2/Bax ratio decreased. Conversely, the levels of intracellular reactive oxygen species (ROS) were increased. The ROS scavenger N-acetylcysteine can significantly inhibit cell cycle arrest and apoptosis induced by ARS. Thus, the data confirmed that ARS exposure impairs normal liver cell proliferation by inducing G0/G1 cell cycle arrest and apoptosis, and this detrimental action may be associated with intracellular ROS accumulation. Collectively, the possible side effects of ARS on healthy normal cells cannot be neglected when developing therapies.

Abstract
Procollagen-lysine, 2-oxoglutarate 5-dioxygenase (PLOD3), also known as lysyl hydroxylase 3 (LH3) has been demonstrated to be overexpressed in several kinds of cancers and facilitate cell migration. Currently, we aimed to reveal the role of PLOD3 in renal cell carcinoma (RCC) progression, and explore whether TWIST1 (Twist family bHLH transcription factor 1) is involved in this process. Fifty-eight paired RCC tissues and normal tissues were collected and subjected to qPCR and immunohistochemistry (IHC) technology to detect the expression levels of PLOD3. The clinical value of PLOD3 in predicting RCC progression was then explored. Cell-Counting Kit-8 (CCK-8), wound healing, transwell chambers and tumor-bearing experiments were applied to monitor cell proliferation, migration, invasion and tumorigenesis. Protein levels were determined by using western blotting technology to assess cell apoptosis and epithelial to mesenchymal transition (EMT). PLOD3 expression was enhanced in RCC tissues and cells, which predicted higher T (tumor), N (lymph node) and M (metastasis) stages, histological grade and TNM (tumor, lymph node, metastasis) stage. PLOD3 downregulation in RCC A498 cells obviously inhibited cell proliferation, migration, invasion, EMT and tumorigenesis and increased cell apoptosis. PLOD3 overexpression led to opposite results in RCC A704 cells. PLOD3 downregulation reduced the expression levels of TWIST1, β-catenin and p-AKT. In addition, TWIST1 overexpression rescued the repressions of cell proliferation, migration, invasion, EMT and the activation of β-catenin and AKT signaling in addition to apoptosis promotion induced by PLOD3 downregulation. Collectively, this study illustrated that PLOD3 knockdown suppressed RCC malignance via inhibiting TWIST1-mediated activation of β-catenin and AKT signaling.

Abstract
Abstract
Introduction
Although the relationships amongst sleep, pain and anxiety have been evidenced, the underlying neurological mechanisms remain elusive. Primary dysmenorrhea is a good model of spontaneous pain with clear painful (menstruation, state) and pain free (e.g., peri-ovulatory phase, trait) conditions. We sought to investigate the state- and trait-related neural signatures that link sleep and anxiety in primary dysmenorrhea.
Methods
Thirty female subjects with primary dysmenorrhea and 30 healthy female controls completed resting-state functional magnetic resonance imaging, the State-Trait Anxiety Inventory and sleep quality assessments during menstruation and peri-ovulatory phases. As we have reported that there was altered default mode network in the primary dysmenorrhea, posterior parietal cortex (PPC) was therefore chosen as the seed to elucidate the functional connectivity that may correlate with sleep and anxiety.
Results
The primary dysmenorrheic subjects exhibited sleep disturbances throughout the menstrual cycle with increased state anxiety. The primary dysmenorrheic subjects demonstrated significantly higher correlations between the sleep quality and the PPC-insula and -putamen functional connectivity during the peri-ovulatory phase. During menstruation, the primary dysmenorrheic subjects demonstrated significantly lower correlations between their state-anxiety scores and the PPC-occipital cortex functional connectivity.
Conclusion
After regressing out the effects of trait anxiety, the correlation between sleep quality and the PPC-putamen functional connectivity was not significant, indicating anxiety-mediated sleep-pain relationship. The PPC-insula functional connectivity, by contrast, was remained significant. Furthermore, state anxiety was associated with the PPC-occipital cortex functional connectivity that was significantly impaired in primary dysmenorrheic subjects. These findings hinted pain and anxiety mediating sleep quality in different neurological circuits.

Abstract
Objective: To analyze the clinical characteristics of 2019 novel coronavirus (2019-nCoV) pneumonia and to investigate the correlation between serum inflammatory cytokines and severity of the disease. Methods: 29 patients with 2019-ncov admitted to the isolation ward of Tongji hospital affiliated to Tongji medical college of Huazhong University of Science and Technology in January 2020 were selected as the study subjects. Clinical data were collected and the general information, clinical symptoms, blood test and CT imaging characteristics were analyzed. According to the relevant diagnostic criteria, the patients were divided into three groups: mild (15 cases), severe (9 cases) and critical (5 cases). The expression levels of inflammatory cytokines and other markers in the serum of each group were detected, and the changes of these indicators of the three groups were compared and analyzed, as well as their relationship with the clinical classification of the disease. Results: (1) The main symptoms of 2019-nCoV pneumonia was fever (28/29) with or without respiratory and other systemic symptoms. Two patients died with underlying disease and co-bacterial infection, respectively. (2) The blood test of the patients showed normal or decreased white blood cell count (23/29), decreased lymphocyte count (20/29), increased hypersensitive C reactive protein (hs-CRP) (27/29), and normal procalcitonin. In most patients,serum lactate dehydrogenase (LDH) was significantly increased (20/29), while albumin was decreased(15/29). Alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (Tbil), serum creatinine (Scr) and other items showed no significant changes. (3) CT findings of typical cases were single or multiple patchy ground glass shadows accompanied by septal thickening. When the disease progresses, the lesion increases and the scope expands, and the ground glass shadow coexists with the solid shadow or the stripe shadow. (4) There were statistically significant differences in the expression levels of interleukin-2 receptor (IL-2R) and IL-6 in the serum of the three groups (P<0.05), among which the critical group was higher than the severe group and the severe group was higher than the mildgroup. However, there were no statistically significant differences in serum levels of tumor necrosis factor-alpha (TNF-α), IL-1, IL-8, IL-10, hs-CRP, lymphocyte count and LDH among the three groups (P>0.05). Conclusion: The clinical characteristics of 2019-nCoV pneumonia are similar to those of common viral pneumonia. High resolution CT is of great value in the differential diagnosis of this disease. The increased expression of IL-2R and IL-6 in serum is expected to predict the severity of the 2019-nCoV pneumonia and the prognosis of patients.

Abstract
Objective: To analyze the clinical characteristics of 2019 novel coronavirus (2019-nCoV) pneumonia and to investigate the correlation between serum inflammatory cytokines and severity of the disease. Methods: 29 patients with 2019-ncov admitted to the isolation ward of Tongji hospital affiliated to Tongji medical college of Huazhong University of Science and Technology in January 2020 were selected as the study subjects. Clinical data were collected and the general information, clinical symptoms, blood test and CT imaging characteristics were analyzed. According to the relevant diagnostic criteria, the patients were divided into three groups: mild (15 cases), severe (9 cases) and critical (5 cases). The expression levels of inflammatory cytokines and other markers in the serum of each group were detected, and the changes of these indicators of the three groups were compared and analyzed, as well as their relationship with the clinical classification of the disease. Results: (1) The main symptoms of 2019-nCoV pneumonia was fever (28/29) with or without respiratory and other systemic symptoms. Two patients died with underlying disease and co-bacterial infection, respectively. (2) The blood test of the patients showed normal or decreased white blood cell count (23/29), decreased lymphocyte count (20/29), increased hypersensitive C reactive protein (hs-CRP) (27/29), and normal procalcitonin. In most patients,serum lactate dehydrogenase (LDH) was significantly increased (20/29), while albumin was decreased(15/29). Alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (Tbil), serum creatinine (Scr) and other items showed no significant changes. (3) CT findings of typical cases were single or multiple patchy ground glass shadows accompanied by septal thickening. When the disease progresses, the lesion increases and the scope expands, and the ground glass shadow coexists with the solid shadow or the stripe shadow. (4) There were statistically significant differences in the expression levels of interleukin-2 receptor (IL-2R) and IL-6 in the serum of the three groups (P<0.05), among which the critical group was higher than the severe group and the severe group was higher than the mildgroup.

Abstract
Objective: To estimate the burden attributed to the dietary inorganic arsenic exposure with lung cancer, bladder cancer and skin cancer as end points. Methods: Inorganic arsenic, food or diet were used as Chinese keywords and arsenic, food and China were used as English keywords to search for literatures related to the dietary inorganic arsenic exposure published by China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform and PubMed Database. Using the data from the China National Nutrition and Health Survey (CNNHS) in 2002 to estimate the dietary inorganic arsenic exposure in Chinese residents. The annual cancer cases attributed to the dietary inorganic arsenic exposure were calculated based on the data from Chinese Cancer Registry Annual Report in 2013. The disability adjusted life year (DALY) was calculated using tools built by WHO. Results: The total DALY of cancer caused by the dietary inorganic arsenic exposure was 419.4 thousand, and the DALY rate was 31.47 per 100 000. The DALY of lung cancer in males and females was 237.7 thousand and 102.5 thousand. The DALY of bladder cancer in males and females was 13.2 thousand and 3.9 thousand. The DALY of skin cancer in males and females was 29.4 thousand and 32.8 thousand. Conclusion: In 2013, the Chinese population had a lower burden of cancer due to the dietary exposure to inorganic arsenic.

Abstract
The present study was aimed to establish a novel TaqMan real-time PCR (RTm-PCR) for detecting and typing bovine viral diarrhea virus (BVDV), and also to develop a diagnostic protocol which simplifies sample collection and processing. Universal primers and TaqMan-MGB probes were designed from the known sequences of conserved 5' - and 3'-untranslated regions (5'UTR, 3'UTR) of the NADL strain of BVDV. Prior to optimizing the assay, cDNAs were transcribed in vitro to make standard curves. The sensitivity, specificity and stability (reproducibility) were evaluated. The RTm-PCR was tested on the 312 feces specimens collected from persistently infected (PI) calves. The results showed the optimum conditions for RTm-PCR were 17.0 μmol/L primer, 7.5 μmol/L probe and 51.4°C annealing temperature. The established TaqMan RTm-PCR assay could specially detect BVDV without detecting any other viruses. Its detection limit was 1.55×100 copies/μL for viral RNA. It was 10000-fold higher than conventional PCR with excellent specificity and reproducibility. 312 samples were tested using this method and universal PCR from six dairy farms, respectively. Positive detections were found in 49 and 44 feces samples, respectively. The occurrence rate was 89.80%. In conclusion, the established TaqMan RTm-PCR could rapidly detect BVDV and effectively identify PI cattle. The detection limit of RTm-PCR was 1.55 copies/μL. It will be beneficial for enhancing diagnosis and therapy efficacy and reduce losses in cattle farms.

Abstract
Autonomous robotic anastomosis has the potential to improve surgical outcomes by performing more consistent suture spacing and bite size compared to manual anastomosis. However, due to soft tissue's irregular shape and unpredictable deformation, performing autonomous robotic anastomosis without continuous tissue detection and three-dimensional path planning strategies remains a challenging task. In this paper, we present a novel three-dimensional path planning algorithm for Smart Tissue Autonomous Robot (STAR) to enable semi-autonomous robotic anastomosis on deformable tissue. The algorithm incorporates (i) continuous detection of 3D near infrared (NIR) markers manually placed on deformable tissue before the procedure, (ii) generating a uniform and consistent suture placement plan using 3D path planning methods based on the locations of the NIR markers, and (iii) updating the remaining suture plan after each completed stitch using a non-rigid registration technique to account for tissue deformation during anastomosis. We evaluate the path planning algorithm for accuracy and consistency by comparing the anastomosis of synthetic vaginal cuff tissue completed by STAR and a surgeon. Our test results indicate that STAR using the proposed method achieves 2.6 times better consistency in suture spacing and 2.4 times better consistency in suture bite sizes than the manual anastomosis.
