Gastric cancer is a common and highly invasive type of malignant tumor, the pathogenesis of which remains unclarified. However, exosomes are now known to play important roles in gastric cancer development and treatment. Cells use exosomes for the packaging and transportation of a variety of bioactive molecules, such as proteins, double-stranded DNA, and micro-ribonucleic acids, to other sites.

Objective: To investigate which indicator is more advantageous when using arterial oxygen saturation (SaO) and fingertip pulse oxygen saturation (SpO) for blood oxygen detection in patients with hyperleukocytic acute leukemia (HAL).
Methods: In this prospective research, the difference between SaO and SpO of 18 HAL patients (observation group) and 14 patients (control group), as well as the relationship between the difference and white blood cell (WBC) counts were analyzed.
Results: SaO was lower than SpO in the observation group ( <0.
The influencing factors of internet fraud, including demographics, psychology, experience and knowledge of susceptibility, have been widely studied. Research on the psychological mechanism of the victimisation process of internet fraud is relatively scarce but suggests a new research perspective. To summarise and unify the research in this field, this study systematically searched and analysed articles on the psychological decision-making mechanism of online fraud victims.

This study systematically retrieved and analyzed articles on the psychological characteristics of older adult victims of online fraud. First, we found that there was no evidence that older adults were more prevalent than other individuals of other ages among online fraud victims, and current researchers have focused more on why older adults are easy targets for fraud (susceptibility to being cheated).

Identification of biomarkers is critical for the treatment of GC. Increasing evidence demonstrates that protein modification plays a pivotal role in carcinogenesis.

Infections in these patients often progress rapidly to sepsis, which is life-threatening.
Aim: To evaluate the diagnostic efficacy of the neutrophil CD64 (nCD64) index, compared to procalcitonin (PCT) and high-sensitivity C-reactive protein (hs-CRP), for the identification of early sepsis in patients with hematological diseases.
At present, many countries have lowered the minimum age of criminal responsibility to deal with the trend of juvenile crime. In practical terms, whether countries advocate for lowering the age of criminal responsibility along with early puberty, or regulating the minimum age of juvenile criminal responsibility through their policies, their deep-rooted hypothesis is that age is tied to adolescents' psychological growth, and, with the rise in age, the capacity for dialectical thinking, self-control, and empathy gradually improves. With this study, we aimed to test whether this hypothesis is valid.

In this Letter, we present a method that allows sub-100-nm lines to be patterned photolithographically using ultrahigh-order modes from a symmetrical metal-cladding waveguide (SMCW) in the near field, which are excited by continuous-wave visible light without focusing. The etching depth of the nanopattern reaches more than 200 nm.

Gastroesophageal reflux disease (GERD) is a common clinical disease associated with upper gastrointestinal motility disorders. Recently, with improvements in living standards and changes in lifestyle and dietary habits, the incidence of GERD has been increasing yearly. However, the mechanism of GERD has not been fully elucidated due to its complex pathogenesis, and this had led to unsatisfactory therapeutic outcomes.

This study aimed to explore the risk factors of lymph node metastasis and prognosis in Siewert II/III AEG patients. Between July 2013 and May 2017, a total of 65 patients who underwent surgical operation in Beijing Friendship Hospital were retrospectively reviewed.

Objective: To improve the method for detecting the neutrophil CD64 (nCD64) index and to enhance the detection rate and accuracy of nCD64 index in patients with hematologic malignancies.
Methods: The nCD64 index in peripheral blood of patients with hematologic malignancies combined with suspicious bacterial infection (255 cases-time) was detected by using array method. When the detection of nCD64 index in samples was interfered with abnormal cells in detection process of enrolled patients, the antibodies CD45, CD15 and CD10 were added into samples on the basis of routine detection by using the primary detection kit, in order to more accurately distinguish the neutrphils and obtain the nCD64 index.

Secretory and membrane proteins are folded in the endoplasmic reticulum (ER) prior to their exit. When ER function is disturbed by exogenous and endogenous factors, such as heat shock, ultraviolet radiation, hypoxia, or hypoglycemia, the misfolded proteins may accumulate, promoting ER stress. To rescue this unfavorable situation, the unfolded protein response is activated to reduce misfolded proteins within the ER.

Objective: To investigate the clinical features of acute myeloid leukemia patients aged over 80 years.
Methods: The clinical data from 24 cases of acute myeloid leukemia (non-M3) aged over 80 years were analyzed retrospectively. Clinical characteristics, therapeutic efficacy and overall survival rate of the patients received low dose chemotherapy and/or decitabine were compared with that received only supportive care.

Malignant hematologic disease with sepsis has been characterized by high mortality and difficulty in diagnosis at early stage. A good biomarker may help to improve the accuracy of diagnosis and to reduce the mortality rate. In the early diagnosis of sepsis, neutrophil CD64 expression is a better candidate for biomarker rather than C-reactive proteins.
