Despite the progress of treatment in gastric cancer (GC), the overall outcomes remain poor in patients with advanced diseases, underscoring the urgency to develop more effective treatment strategies. BH3-mimetic drugs, which inhibit the pro-survival BCL2 family proteins, have demonstrated great therapeutic potential in cancer therapy. Although previous studies have implicated a role of targeting the cell survival pathway in GC, the contribution of different pro-survival BCL2 family proteins in promoting survival and mediating resistance to current standard therapies in GC remains unclear.

Background: Whether patients with diffuse gastric cancer, which is insensitive to chemotherapy, can benefit from neoadjuvant or adjuvant chemotherapy has long been controversial.
Aim: To investigate whether perioperative chemotherapy can improve survival of patients with locally advanced diffuse gastric cancer.
Methods: A total of 2684 patients with locally advanced diffuse gastric cancer from 18 population-based cancer registries in the United States were analyzed.
Background: The prognostic nutritional index (PNI), a marker of immune-nutrition balance, has predictive value for the survival and prognosis of patients with various cancers.
Aim: To explore the clinical significance of the preoperative PNI on the prognosis of ampullary adenocarcinoma (AC) patients who underwent curative pancreaticoduodenectomy.
Methods: The data concerning 233 patients diagnosed with ACs were extracted and analyzed at our institution from January 1998 to December 2020.
Background: Impatiens is an important genus with rich species of garden plants, and its distribution is extremely extensive, which is reflected in its diverse ecological environment. However, the specific mechanisms of Impatiens' adaptation to various environments and the mechanism related to lignin remain unclear.
Results: Three representative Impatiens species,Impatiens chlorosepala (wet, low degree of lignification), Impatiens uliginosa (aquatic, moderate degree of lignification) and Impatiens rubrostriata (terrestrial, high degree of lignification), were selected and analyzed for their anatomical structures, lignin content and composition, and lignin-related gene expression.
Background: The preoperative total bilirubin-albumin ratio (TBAR) and fibrinogen-albumin ratio (FAR) have been proven to be valuable prognostic factors in various cancers.
Aim: To detect the prognostic value of TBAR and FAR in ampullary adenocarcinoma (AC) patients who underwent curative pancreaticoduodenectomy.
Methods: AC patients who underwent curative pancreaticoduodenectomy in the National Cancer Center of China between 1998 and 2020 were retrospectively reviewed.

Background: Textbook outcomes (TOs) have been used to assess the quality of surgical treatment for many digestive tumours but not ampullary carcinoma (AC).
Aim: To discuss the factors associated with achieving a TO and further explore the prognostic value of a TO for AC patients undergoing curative pancreaticoduodenectomy (PD).
Methods: Patients who underwent PD at the China National Cancer Center between 1998 and 2020 were identified.
Background: Both hepatoid adenocarcinoma of the stomach (HAS) and neuroendocrine differentiation (NED) are rare histological subtypes of gastric cancer with unique clinicopathological features and unfavorable outcomes. HAS with NED is even rarer.
Case Summary: Here, we report a 61-year-old man with HAS with NED, as detected by gastric wall thickening by positron emission tomography/computed tomography for a pulmonary nodule.
Background: The effect of perioperative blood transfusion (PBT) on the prognosis of ampullary carcinoma (AC) is still debated.
Aim: To explore the impact of PBT on short-term safety and long-term survival in AC patients who underwent pancreaticoduodenectomy.
Methods: A total of 257 patients with AC who underwent pancreaticoduodenectomy between 1998 and 2020 in the Cancer Hospital, Chinese Academy of Medical Sciences, were retrospectively analyzed.
Background: Growing evidence shows that pancreatic tumors in different anatomical locations have different characteristics, which have a significant impact on prognosis. However, no study has reported the differences between pancreatic mucinous adenocarcinoma (PMAC) in the head the body/tail of the pancreas.
Aim: To investigate the differences in survival and clinicopathological characteristics between PMAC in the head and body/tail of pancreas.
Background: The impact of racial and regional disparity on younger patients with gastric cancer (GC) remains unclear.
Aim: To investigate the clinicopathological characteristics, prognostic nomogram, and biological analysis of younger GC patients in China and the United States.
Methods: From 2000 to 2018, GC patients aged less than 40 years were enrolled from the China National Cancer Center and the Surveillance Epidemiology and End Results database.
Background: The tumor microenvironment (TME) plays an important role in the growth and expansion of gastric cancer (GC). Studies have identified that CD93 is involved in abnormal tumor angiogenesis, which may be related to the regulation of the TME.
Aim: To determine the role of CD93 in GC.
Background: Gastric neuroendocrine carcinoma (GNEC) is a rare histological subtype of gastric cancer, which is categorized into small cell and large cell neuroendocrine carcinomas. It is characterized by strong invasiveness and poor prognosis. Mixed large and small cell neuroendocrine carcinoma (L/SCNEC) is an extremely rare pathological type of gastric cancer, and there have been no reports on this situation until now.

To understand how Nicotiana benthamiana responds to dark stress, the proteomes and metabolomes of leaves treated with darkness were studied. In total, 5763 proteins and 165 primary metabolites were identified following dark treatment.

Here, we found two neurophysiological pathways of heart-brain interaction based on the relationship between oxygen-transport by red blood cells (RBCs) and consciousness/attention. To this end, we collected a dataset based on the routine physical examination, the breaking continuous flash suppression (b-CFS) paradigm, and an attention network test (ANT) in 140 immigrants under the hypoxic Tibetan environment.

The transcriptions of these EBGs are also induced by sucrose signal. However, whether MYB12 is activated by sucrose signal and what the other roles MYB12 has in regulating plant metabolism are poorly understood.

Methods: Forty male SD rats were randomly divided into 4 groups, a endotoxin group, an EA group, a normal group and a non-acupoint group. Hepatic injury rat model was prepared by injection of endotoxin (5 mg/kg) into the caudal vein, the normal group received the injection of the equal amount of saline; for the EA group, EA (2-100 Hz, 2 mA, 1.
