Abstract
BACKGROUND Currently, the value of oral selective estrogen receptor degraders (SERDs) for hormone receptor-positive (HR+) and human epidermal growth factor receptor 2-negative (HER2-) advanced breast cancer (aBC) after progression on ≥ 1 line of endocrine therapy (ET) remains controversial. We conducted a meta-analysis to evaluate progression-free survival (PFS) and safety benefits in several clinical trials. MATERIALS AND METHODS Cochrane Library, Embase, PubMed, and conference proceedings (SABCS, ASCO, ESMO, and ESMO Breast) were searched systematically and comprehensively. Random effects models or fixed effects models were used to assess pooled hazard ratios (HRs) and 95% confidence intervals (CIs) for treatment with oral SERDs versus standard of care. RESULTS A total of four studies involving 1,290 patients were included in our analysis. The hazard ratio (HR) of PFS showed that the oral SERD regimen was better than standard of care in patients with HR+/HER2- aBC after progression on ≥ 1 line of ET (HR: 0.75, 95% CI: 0.62-0.91, p = 0.004). In patients with ESR1 mutations, the oral SERD regimen provided better PFS than standard of care (HR: 0.58, 95% CI: 0.47-0.71, p < 0.00001). Regarding patients with disease progression following previous use of CDK4/6 inhibitors, PFS benefit was observed in oral SERD-treatment arms compared to standard of care (HR: 0.75, 95% CI: 0.64-0.87, p = 0.0002). CONCLUSIONS The oral SERD regimen provides a significant PFS benefit compared to standard-of-care ET in patients with HR+/HER2- aBC after progression on ≥ 1 line of ET. In particular, we recommend oral SERDs as a preferred choice for those patients with ESR1m, and it could be a potential replacement for fulvestrant. The oral SERD regimen is also beneficial after progression on CDK4/6 inhibitors combined with endocrine therapy.

Abstract
African swine fever (ASF) is one of the most devastating hemorrhagic infectious diseases that affect pigs and wild suids due to the lack of a vaccine or an effective treatment. The large dsDNA genome of African swine fever virus (ASFV) contains up to 167 ORFs that are predicted to encode proteins. Since its introduction to China in 2018, this genome has aroused the enthusiasm of researchers throughout the world. Here, we review the research progress on ASFV in recent years. Given the importance of this disease, this review will highlight recent discoveries in basic virology, focusing mainly on epidemiology, virulence, pathogenic mechanisms, diagnosis, vaccine development, and treatment; this will help in understanding virus-host interactions and disease prevention regarding ASFV.

Abstract
Due to the high incidence of COVID-19 case numbers internationally, the World Health Organization (WHO) declared a Public Health Emergency of global relevance, advising countries to follow protocols to combat pandemic advance through actions that can reduce spread and consequently avoid a collapse in the local health system. This study aimed to evaluate the dynamics of the evolution of new community cases, and mortality records of COVID-19 in the State of Pará, which has a subtropical climate with temperatures between 20 and 35 °C, after the implementation of social distancing by quarantine and adoption of lockdown. The follow-up was carried out by the daily data from the technical bulletins provided by the State of Pará Public Health Secretary (SESPA). On 18 March 2020, Pará notified the first case of COVID-19. After 7 weeks, the number of confirmed cases reached 4756 with 375 deaths. The results show it took 49 days for 81% of the 144 states municipalities, distributed over an area of approximately 1 248 000 km2 to register COVID-19 cases. Temperature variations between 24.5 and 33.1 °C did not promote the decline in the new infections curve. The association between social isolation, quarantine and lockdown as an action to contain the infection was effective in reducing the region's new cases registration of COVID-19 in the short-term. However, short periods of lockdown may have promoted the virus spread among peripheral municipalities of the capital, as well as to inland regions.

Abstract
Most gastric cancer (GC) cases are diagnosed at an advanced stage in China. Because of its high morbidity and mortality, GC remains a major health crisis in China. Surgical resection is the only potentially curative treatment for GC. Owing to being minimally invasive, laparoscopic radical gastrectomy has been widely used in various countries, especially in East Asia, since Kitano first reported the feasibility and safety of this technique. Although laparoscopic gastric surgery was introduced relatively late in China, Chinese surgeons have made unique contributions to the research and clinical practice of laparoscopic gastric surgery due to the large number of clinical cases. This review focuses on the progress in laparoscopic gastrectomy for advanced stage GC in China, including reasonable approaches in different areas and oncologic efficacy of laparoscopic surgery, and introduce advanced technology to facilitate surgeons to rapidly overcome the learning curve in clinical practice.

Abstract
Advance care planning is an opportunity for patients to express their priorities for future care. NHS England has outlined a commitment to end-of-life care, advocating a shift towards more patient-centred care. The NHS is encouraging the workforce to engage patients in conversations about what is important to them, shifting the focus from 'what is wrong with you' to 'what matters to you'. Traditionally, this was seen as the doctor's role but this conversation can and should happen with the wider skilled medical workforce. The key to advance care planning is to have these conversations early on when patients have the capacity to discuss their preferences for care. Advance care planning can occur in any setting where the patient is comfortable to have the conversation, be that at home, in the GP surgery, in hospital or another setting. Patients with advance care plans are more likely to have their wishes respected, have fewer unwanted interventions, experience reduced transitions between care settings and are more likely to die in their preferred place of death. Healthcare professionals have a duty to offer advance care planning to patients nearing the last phase of life so that care can be delivered to honour individual needs at the end of life.

Abstract
OBJECTIVE This study was to review the efficacy of surgical resections in different clinical situations for a better understanding of the meaning of surgery in the treatment of neuroblastoma (NB). DATA SOURCES The online database ScienceDirect (201-2018) was utilized. The search was conducted using the keywords "neuroblastoma," "neuroblastoma resection," "neuroblastoma surgery," and "high-risk neuroblastoma." STUDY SELECTION We retrospectively analyzed of patients who underwent surgical resections in different clinical situations. The article included findings from selected relevant randomized controlled trials, systematic reviews, and meta-analyses or good-quality observational studies. Abstracts only, letters, and editorial notes were excluded. Full-text articles and abstracts were extracted and reviewed to identify key articles discussing surgery management of NB, which were then selected for critical analysis. RESULTS A total of 7800 English language articles were found containing references to NB (201-2018). The 163 articles were searched which were related to the surgical treatment of NB (201-2018). Through the analysis of these important articles, we found that the treatments of NB at low- and intermediate-risk groups were basically the same. High-risk patients remained controversial. CONCLUSIONS NB prognosis varies tremendously based on the stage and biologic features of the tumor. After reviewing the relevant literature, patients with low-risk disease are often managed with surgical resection or observation alone with tumors likely to spontaneously regress that are not causing symptoms. Intermediate patients are treated with chemotherapy with the number of cycles depending on their response as well as surgical resection of the primary tumor. High-risk patients remain controversial. Multidisciplinary intensive treatment is essential, especially for patients who received subtotal tumor resection. Minimally invasive surgery for the treatment of NBs without image-defined risk factors in low- to high-risk patients is safe and feasible and does not compromise the treatment outcome. We conclude that ≥90% resection of the primary tumor is both feasible and safe in most patients with high-risk NB. New targeted therapies are crucial to improve survival.

Abstract
Hepatitis E virus (HEV) infection is an emerging zoonotic disease posing a severe threat to public health in the world, especially to pregnant women. Currently, no specific treatments are available for HEV infection. Therefore, it is crucial to develop vaccine to prevent this infection. Although several potential candidate vaccines against HEV have been studied for their immunogenicity and efficacy, only Hecolin® which is developed by Xiamen Innovax Biotech Co., Ltd. and approved by China Food and Drug Administration (CFDA) in 2012, is the licensed HEV vaccine in the world so far. Extensive studies on safety, immunogenicity and efficacy in phase III clinical trials have shown that Hecolin® is a promising vaccine for HEV prevention and control. In this article, the advances on HEV vaccine development and research are briefly reviewed.

Abstract
There is increasing evidence that sleep and circadian disruption can worsen the disease course in inflammatory bowel disease (IBD). Sleep and circadian disruption are prevalent in society and are associated with worse outcomes in IBD. Emerging research suggests sleep and circadian disruption can impact key components in IBD disease flares, including intestinal permeability, translocation of bacterial endotoxins, intestinal dysbiosis, and proinflammatory cytokines. Much of this research has been conducted in animal models. There is a clear need for large randomized controlled trials in human patients with IBD, where the potential for chronotherapeutic strategies to improve disease course can be tested.

Abstract
Colorectal cancer is one of the most common malignant tumors and the fourth cause of cancer-related mortality. It is not easy to be found at the early stage and therefore has a poor prognosis. Thus, new molecular biomarkers are required to improve early diagnosis and discover new effective therapeutic targets. Advances in proteomic technologies have greatly enhanced our understanding of the pathogenesis of colorectal cancer at the protein level, and improved our ability of early diagnosis and treatment. Proteomic studies of colorectal tissues, serum and cell lines have identified differentially expressed proteins, new potential diagnostic biomarkers and clinical drug targets. This article reviews the advances in proteomic study of colorectal cancer in recent years.

Abstract
Studies have shown a relationship between circadian rhythm disruptions and type-2 diabetes. This investigation examined the effects of circadian disruption (6-h phase advances) on the progression of diabetes in a type-2 diabetic mouse model -TALLYHO/JngJ - and whether wheel-running can alleviate the effects of the phase advances. 6-h advances alter fasting glucose, glucose tolerance and insulin production. Wheel-running reduced body mass, improved glucose tolerance and reduced insulin in TALLYHO/JngJ and alleviated some of the changes in diabetic symptoms due to 6-h advances. These results indicate that individuals with type-2 diabetes can benefit from physical activity and exercise can be a countermeasure to offset the effects of an acute phase advance.

Abstract
Rectal neoplasms pose serious harm to human health. The options of surgical procedure for these patients have been limited because of the special features of anal and rectal anatomy and physiology. Tumors with a diameter less than 3 cm can be resected through the anus or soft microscope; however, those with a large diameter and wide base which are cancerous and relapse easily still need conventional laparotomy procedures. Transanal endoscopic microsurgery (TEM) was designed to avoid laparotomy for these patients. Using special instruments, TEM allows to totally resect tumors located 4-25 cm from the anus with safe margin and lower rate of complications. Because of minimal invasiveness, shorter operative time and lower rate of complications, TEM can be widely applied in rectal polyps and adenomas. Currently, there are still arguments about TEM usage in early-stage and advanced rectal cancer. This paper reviews the current situation of application and research of TEM, with emphasis put on its indications, clinical efficiency and future development.

Abstract
Acute liver failure occurs abruptly with rapid progression. Traditional medical treatment and simple non-bioartificial liver support system cannot reverse the prognosis of acute liver failure (ALF), and liver transplantation is the only effective treatment. However, donor liver shortage, the need of a life-long immunosuppressive therapy as well as complex postoperative complications make ALF patients facing a variety of challenges in the perioperative period of liver transplantation, which are directly related to the success rate of surgery and the mortality. This article aims to discuss perioperative difficulties and preventive measures in liver transplantation for ALF by exploring how to extend the lives of patients before liver transplantation and how to deal with postoperative complications.

Abstract
AIM: To evaluate the three-dimensional (3-D) representation performance of 4 publicly available Shape-from-Shading (SfS) algorithms in small-bowel capsule endoscopy (SBCE).
METHODS: SfS techniques recover the shape of objects using the gradual variation of shading. There are 4 publicly available SfS algorithms. To the best of our knowledge, no comparative study with images obtained during clinical SBCE has been performed to date. Three experienced reviewers were asked to evaluate 54 two-dimensional (2-D) images (categories: protrusion/inflammation/vascular) transformed to 3-D by the aforementioned SfS 3-D algorithms. The best algorithm was selected and inter-rater agreement was calculated.
RESULTS: Four publicly available SfS algorithms were compared. Tsai’s SfS algorithm outperformed the rest (selected as best performing in 45/54 SBCE images), followed by Ciuti’s algorithm (best performing in 7/54 images) and Torreão’s (in 1/54 images). In 26/54 images; Tsai’s algorithm was unanimously selected as the best performing 3-D representation SfS software. Tsai’s 3-D algorithm superiority was independent of lesion category (protrusion/inflammatory/vascular; P = 0.678) and/or CE system used to obtain the 2-D images (MiroCam®/PillCam®; P = 0.558). Lastly, the inter-observer agreement was good (kappa = 0.55).
CONCLUSION: 3-D representation software offers a plausible alternative for 3-D representation of conventional capsule endoscopy images (until optics technology matures enough to allow hardware enabled-“real” 3-D reconstruction of the gastrointestinal tract).

Abstract
The etiology and pathogenesis of gastric cancer (GC) are still elusive. Genetic factors, environmental factors and immune factors may play a role in the development of GC. While GC is progressing, tumor cells always induce immune cell apoptosis or immune system dysfunction to acquire immune privilege or immune evasion. It has been known that CD4+ T cells, CD8+ T cells, the B7 ligand family and dendritic cells are involved in these processes. GC immunotherapy, which can be antigen-specific or -nonspecific, has been an important part of adjuvant therapy. IL-2 is one of the most commonly used cytokines in GC-nonspecific immunotherapy and has been demonstrated to have certain curative effect. Administration of dendritic cell-based tumor vaccines will become a new approach for GC-specific immunotherapy.

Abstract
OBJECTIVE Retrospective evaluation of the outcome of stage IVB, recurrent or persistent cervical cancer treated with cisplatin and generic topotecan (CT) in a tertiary care hospital in Thailand. METHODS The medical records of patients treated with CT regimen at Chiang Mai University Hospital between January 2005 and December 2007 were reviewed and analyzed. The treatment protocol consisted of IV topotecan 0.75 mg/m(2) on days 1, 2, and 3; combined with cisplatin 50 mg/m(2) IV on day 1 and repeated every 21 days until progression or unacceptable toxicity for a maximum of 6 cycles. The outcomes were evaluated based on the response rate, progression free survival (PFS), and overall survival (OS) by using the World Health Organization criteria. The adverse effects of the treatments were also determined. RESULTS Twenty-one cervical cancer patients received the CT regimen. The tumor response rate was 28.6%. The median PFS and OS was 4 and 11 months, respectively. With 87 cycles of chemotherapy, the most common grade 3 & 4 hematologic toxicity was neutropenia (57.9%). CONCLUSION Advanced and recurrent cervical cancer patients treated with cisplatin and generic topotecan had a favorable outcome with manageable toxicity.

Abstract
Neurotrophins (NT) play an important role in the process of neuronal growth, development, protection and repair. In recent years, great advances have been achieved in the research of neurotrophins. Glial cell line-derived neurotrophic factor is a nutritional factor that has the most potential to promote neuronal growth, differentiation and repair. It can also modulate intestinal neuronal growth and neurotransmitter expression. Brain-derived neurotrophic factor plays an important role in the development of the enteric nervous system, intestinal infection, and the modulation of gastrointestinal motility. Neurotrophin-3 can increase excitatory peptides that are expressed by neurons in the intestinal muscularis to accelerate colonic transit. Ciliary neurotrophic factor and other neurotrophins have a synergistic effect on neurons. In this article, we will review the recent advances in understanding the role of neurotrophins in physiological and pathological processes in the intestinal tract.

Abstract
Irritable bowel syndrome (IBS) is one of the most common functional gastrointestinal disorders and represents a major public health problem. The advances in understanding the pathophysiology and pathogenesis of IBS have revolutionized the treatment modality for the disease. Currently commonly used drugs for IBS include drugs acting on serotonin receptors or serotonin transporters, antidepressants, selective chloride channel activators, cholecystokinin antagonists, atypical benzodiazepines, antibiotics, probiotics and herbal medicine. In recent years, there has been public concern over several new drugs for IBS (i.e., alosetron and tegaserod) because of their association with ischemic colitis and cardiovascular disease. A series of systematic reviews and randomized controlled trials have been performed to evaluate the efficacy of different treatments for IBS.

Abstract
Nonalcoholic steatohepatitis (NASH) is a pathological condition characterized by macrovesicular steatosis, necroinflammation, loss of hepatocytes and fibrosis. NASH is often associated with type 2 diabetes mellitus, hypertension, hyperlipoproteinemia and obesity. Recent studies emphasize the role of insulin resistance, oxidative stress and subsequent lipid peroxidation, proinflammatory cytokines, adipokines and mitochondrial dysfunction in the development and progression of NASH. In this article, we will review the role of insulin resistance, oxidative stress and subsequent lipid peroxidation, mitochondrial dysfunction, proinflammatory cytokines, adipokines such as resistin, leptin, adiponectin and PPAR-α, apoptosis, NF kappa B, SREBP-1c, endotoxaemia, and iron overload in the pathogenesis of NASH. The pathogenesis of NASH is thought to be related mainly with insulin resistance and oxidative stress and subsequent lipid peroxidation. Adipocytokines also play an important role in the pathogenesis of NASH through complex and interactive paracrine and endocrine mechanisms. Understanding of the mechanisms responsible for the pathogenesis of NASH has important implications for the treatment of NASH.

Abstract
AIM: To investigate the anti-diarrhea effect of EA303 (an estrone derivative) in mice and explore the mechanisms involved.
METHODS: Diarrhea was induced in mice by cathartics (castor oil, magnesium sulfate or liquid paraffin). At various time points following oral administration of a single dose of EA303 (14.87, 29.74 or 59.48 mg/kg) , the diarrhea index was determined. The effect of EA303 on intestinal propulsion was evaluated using the charcoal meal method. The effect of different concentrations of EA303 (10-5, 3 × 10-5 and 10-4 mol/L) on isolated intestinal smooth muscle of rabbits was also evaluated.
RESULTS: Compared with normal saline, EA303 at various doses tested could significantly decrease diarrhea indices at various time points following dosing; high-dose EA303 (59.48 mg/kg) could significantly reduce the intestinal propulsion rate of charcoal meal in mice (58.53% ± 14.12% vs 78.41% ± 15.91%, P < 0.01); and EA303 at various doses tested (high-, medium- and low-dose) could significantly postpone the defecation of mice (116.40 ± 17.69 min, 114.40 ± 45.76 min and 101.50 ± 50.02 min vs 78.10 ± 15.98 min, respectively; all P < 0.01). Compared with pretreatment baseline values, EA303 at concentrations of 3 × 10-5 mol/L and 10-4 mol/L significantly inhibited the contraction amplitude of isolated intestinal smooth muscle from rabbits (43.26% ± 14.83% and 16.70% ± 10.89% vs 100.00% ± 0.00%, respectively; both P < 0.01), while EA303 at a concentration of 10-4 mol/L significantly decreased the contraction tension of isolated intestinal smooth muscle from rabbits (58.94% ± 7.16% vs 100.00% ± 0.00%, P < 0.01).
CONCLUSION: EA303 can exert an anti-diarrhea effect perhaps through lowering contraction amplitude and tension of intestinal smooth muscle.

Abstract
Malignancies in digestive system (MIDS) are most common and they are major causes of tumor death in the world. Despite recent advances, patients with MIDS still have very poor prognosis. With the development of tumor molecular biology, especially clarification of the mechanism underlying molecular signaling pathway for tumor cell proliferation and growth, researchers have started a new field and direction of clinical tumor therapy, i.e., molecular targeted therapy, which was essentially effective in tumor treatment. This article elucidates the current status, latest advances and developing trends of molecular targeted therapy for MIDS.

Abstract
Hepatitis B virus (HBV) infection is a major global health problem. A complex combination of environment and virus, especially host genetic factors, play a critical role in determining both susceptibility to HBV persistence and different clinical outcomes after HBV infection. In this review, we summarized the main relevant genes such as human leukocyte antigen (HLA), tumor necrosis factor (TNF), interleukins (ILs), interferons (IFNs), etc. However, in order to identify all the relevant polymorphisms that affect the outcome of HBV infection, alternative strategies such as genome-wide association studies with large sample sizes are required to define the majority of the related genes.
