ObjectiveTo summarize the recent research progress of circRNA in gastric cancer, and to explore the clinical value of circRNA as new therapeutic target and diagnostic or prognostic biomarker for gastric cancer.MethodThe studies on circRNA and related literatures in gastric cancer were reviewed.ResultsAs a new member of the non-coding RNA family, circRNA played a key role in regulating the proliferation, invasion, migration, apoptosis, and therapeutic resistance of gastric cancer cells. At the same time, based on the stability and tissue-specific characteristics, circRNA possessed great potential as biomarker for early diagnosis or prognosis evaluation of gastric cancer.ConclusionscircRNA plays an important role in the initiation and progression of gastric cancer. As a diagnostic and prognostic biomarker and a new therapeutic target for gastric cancer, circRNA has great potential for clinical transformation.
Objective To elucidate the new concept and theory of neurorestoratology. Methods With the review of the development course and important research works in the field of neurorestoratology during the 20th century, especially recent 30 years, the regularity summary, science and technology philosophy induction, and theory distillation were carried out in this article. Results The new discipl ine system was brought forward as follows: ① Definition: neurorestoratology was asub-discipl ine of neuroscience which studies neural regeneration, neural structural repair of replacement, eruroplasticity and neuromodulation. The core purpose was to promote neural functional recovery of all neural degenerative diseases and damages. ② One central task and two basic points: to recover neurological function was the central research task all the time and the two basic points were the precl inical (basic) neurorestoration and the cl inical neurorestoration. ③ Four rationale of the discipl ine: l imited renovation, relearning, insufficient reserve, and l ifelong reinforcement. ④ Five major factors of neurorestoratology (5N’s dogma): neuroregeneration, neurorepair, neuroplasticity, neuromodulation, neurorehabil itation. “Neuroprotection” appeared to be included in the broad definition. ⑤ Four-step rule of neurorestoratology: structural neurorestoration, signal neurorestoration, rehabil itative neurorestoration, and functional neurorestoration. ⑥ Emphasize that translational medicine from lab to bed in neurorestoration. Conclusion The discipl ine of neurorestoratology has the vast development prospectand will be sure to increase the rapid progress of the basic and cl inical restorative neuroscience.
ObjectiveTo compare the three-dimensional (3D) laparoscopic simulator with two-dimensional (2D) laparoscopic simulator in training of laparoscopic novices.MethodsBetween January 2018 and December 2019, surgical residents from Chinese PLA General Hospital were enrolled, which were grouped into 3D and 2D group. After receiving training program, novices in both two groups subject to performance examination, including bean-picking module, exchange module, transfer module, needle-manipulating module, and suture module. Times and errors were compared between the two groups for each module.ResultsA total of 16 novices in 3D group and 15 novices in 2D group were enrolled, and baseline characteristics including age, gender, major hand, glass wearing, laparoscopic experience, and shooting game experience were well balanced between the two groups (P>0.05). There were comparable times and errors between the two groups in terms of bean-picking module and exchange module (P>0.05). The time of transfer module and needle-manipulating module was not significant between the two groups (P>0.05), but novices in 3D group performed more precise than those in 2D group (P<0.05). In suture module, 3D group had shorter time (P=0.02) and higher accuracy (P=0.03).Conclusion3D laparoscopic simulator can shorten novice performance time in complex procedures, improve accuracy, and facilitate laparoscopic training.
New functional evaluation methods for coronary artery lesions have received widespread attention at home and abroad. As a new functional evaluation technique, the clinical value of quantitative flow ratio (QFR) in the accuracy and feasibility of diagnosing myocardial ischemia caused by coronary artery stenosis has been confirmed in many clinical trials. Compared with the traditional gold standard fractional flow reserve (FFR) for diagnosing coronary artery stenosis, QFR has the advantages of simple operation, time-saving and low cost. This article reviews the comparison of the diagnostic accuracy of FFR and QFR and the progress of clinical research, aiming to explore whether QFR may replace FFR as a functional evaluation method of coronary artery disease and guide clinical blood circulation reconstruction.
In 2019, the American Wilderness Medical Society updated and released a new version of the practice guidelines based on the practice guidelines for the prevention and treatment of acute altitude illness first published in 2010 and updated in 2014. This article interprets the guidelines, focusing on effective measures to prevent and treat different forms of acute altitude illness, as well as suggestions for specific methods to manage the disease, with a view to providing help for clinicians in better practice.

Methods The clinical data of one patient with pancreatic cancer on the 8th July, 2009 was retrospectively analyzed. The chief complaints included abdominal distension and vomiting. Results By exploratory surgery in time,the patient was diagnosed as pancreatic cancer and underwent the resection. Conclusion The onset of pancreatic cancer is very insidious,usually with a high misdiagnosis rate. How to make the right early diagnosis and to avoid misdiagnosis are the focal points of improving the prognosis.
Previous studies have shown that growth arrest, dedifferentiation, and loss of original function occur in cells after multiple generations of culture, which are attributed to the lack of stress stimulation. To investigate the effects of multi-modal biomimetic stress (MMBS) on the biological function of human bladder smooth muscle cells (HBSMCs), a MMBS culture system was established to simulate the stress environment suffered by the bladder, and HBSMCs were loaded with different biomimetic stress for 24 h. Then, cell growth, proliferation and functional differentiation were detected. The results showed that MMBS promoted the growth and proliferation of HBSMCs, and 80 cm H2O pressure with 4% stretch stress were the most effective in promoting the growth and proliferation of HBSMCs and the expression level of α-smooth muscle actin and smooth muscle protein 22-α. These results suggest that the MMBS culture system will be beneficial in regulating the growth and functional differentiation of HBSMCs in the construction of tissue engineered bladder.

With chronic kidney disease becoming a public health problem in the world, dialysis treatment model has also become the focus of attention from all walks of life. Sustained low-efficiency dialysis, which adopts the mode of low blood flow and low dialysis volume, is a kind of hybrid renal replacement therapy combining continuous renal replacement therapy and intermittent hemodialysis. It has unique advantages in the treatment of patients with acute and severe renal injury, as well as the dialysis duration, patient activity range and cost. It is the most widely used hybrid renal replacement therapy too. This review summarizes the clinical application and nursing points of sustained low-efficiency dialysis to provide guidance for clinical practice.
Patients with chronic diseases usually face severe challenges during their transition from hospital to home, such as poor discharge preparation, the increased incidence of medical errors, insufficient self-care capability, and poor participation in healthcare decision, which can result in increased readmission and poor patient safety. This paper reviews the definition of transitional care, single-element transitional care intervention strategy, and multiple-element transitional care intervention strategy, in order to provide new insights into the development of effective and safe transitional care strategies in China.
