In order to expand the capabilities of hospital's traditional ECG device and enhance medical staff's work efficiency, an ECG monitoring system based on internet of things is introduced. The system can monitor ECG signals in real time and analyze data using ECG sensor, PDA, Web servers, which embeds C language, Android systems, .NET, wireless network and other technologies. After experiments, it can be showed that the system has high reliability and stability and can bring the convenience to medical staffs.

Objective: Medical waste management is not only the problem of hospital, but also is an important public health problem. Apply modern information technology to insure real-time tracking and monitoring medical waste recycling, storage, disposal, improve medical waste management. Methods: Construct medical waste management system with wireless network, bar code and RFID etc. Results:By this system, transportation, storage and disposal that process of medical waste within the hospital are monitoring and supervision effective. Conclusion:The collection and transportation sectors of medical waste have been standard, to ensure the security, enhanced transparency and improved hospital management.

An inteligent beds monitoring system based on sensor technology is developed. Through the instalation of sensors in the bed, the patient’s vital signs like heart rate, breathing rate can be acquired, other information such as rol over, in/out of bed can be real-time monitored. Also, the system can automaticaly analysis data and remind the nurse if abnormal events happened. After one year's clinical application, the system received the affi rmation from patients and medical staff.

We report a case of a male patient who developed persistent fever and central nervous system symptoms after eating raw snails for 10 days. The patient was diagnosed with Angiostrongyliasis depended on the clinical presentation, epidemiological history, and etiological results. The patient recovered after receiving albendazole anthelmintic and dexamethasone anti-inflammatory therapy. This article incorporates literature review to sort out the diagnosis and treatment of this patient, in order to provide feasible reference for clinicians.

Objective: To investigate the clinicopathological features and molecular phenotypes of gastric cancer with enteroblastic dif-ferentiation (GCED). Methods: A retrospective analysis of 337 patients with gastric adenocarcinoma diagnosed by the pathology de-partment of the First Affiliated Hospital of Zhejiang University in March 2013-2017 was conducted. Of them, 8 patients were diag-nosed with gastric carcinoma with intestinal blastocyte differentiation. All the patients were elderly, including 6 men and 2 women. The onset age was 68-83 years (mean 76.6 years). Two cases had serum AFP≥200 μg/L before treatment. According to the histopatho-logical morphology, the immunophenotype was analyzed by immunohistochemistry, the SALL4 gene was detected using reverse tran-scription-polymerase chain reaction (RT-PCR), and the relevant literature was reviewed. Results: Microscopically, all cases had primi-tive enteroid structures, consisting of cubic or columnar cells with clear cytoplasm, and immunohistochemical staining showed positivi-ty for either AFP and GPC3 or SALL4. The expression of SALL4 mRNA was significantly increased by RT-PCR. Follow-up from 1 to 5 years showed that 5 patients had liver and other organ metastases, 2 patients died, and 1 patient survived without a tumor. Conclusions:GCED is a rare invasive gastric adenocarcinoma with a worse prognosis than that of normal intestinal adenocarcinoma. The treatment of general intestinal adenocarcinoma has little effect. There are some characteristic changes in histology. It would be helpful for diag-nosis and differential diagnosis if clinicians are familiar with the tumor spectrum and genetic characteristics. Target therapy for an origi-nal marker, such as SALL4, has a bright future.

Immune checkpoint inhibitors (ICIs) have been widely used in management of malignant tumor. Programmed death ligand 1 (PD-1)/programmed death ligand 1 (PD-L1) inhibitors have been introduced to treat non-small cell lung cancer (NSCLC) in recent years. Currently, PD-1/PD-L1 inhibitors are considered to have minor side effects and do not independently increase the risk of infection. However, they may cause immune-related adverse events (irAEs) that can require immunosuppressive therapy with corticosteroids and/or immunosuppressants, leading to opportunistic infections. Furthermore, there were reports about reactivation of chronic/latent infections without irAEs. Thus, immune checkpoint inhibitor related infections have drawn more and more attention in the world. In this paper, we described the potential mechanism, available clinical data and recommendation of diagnosis and management for PD-1/PD-L1 inhibitor related infections.
