1.Reperfusion strategy for patients with ST-segment elevation myocardial infarction in hospitals without PCI facility
Medical Journal of Chinese People's Liberation Army 1983;0(05):-
Thrombolysis is still an important treatment modality in patients with ST-segment elevation myocardial infarction (STEMI) in a hospital without percutaneous coronary intervention (PCI) facility. However, the optimal treatment after thrombolysis is still unclear. Conservative treatment after thrombolysis was recommended in the past. "Guidelines for percutaneous coronary intervention (2009)" also suggested that the condition of STEMI patients should be evaluated to determine whether the patient should be transferred to a hospital with PCI facility. But this suggestion lacksed evidence-based support. In recent years, several clinical trials suggested that immediate transfer to the nearest interventional centre for PCI was plausible regardless of success or failure in thrombolysis in local hospital, and this might reduce the incidence of cardiovascular events in patients with STEMI.

Journal of Leukemia & Lymphoma 2014;23(7):401-404
Objective To investigate mRNA expression levels of cathepsin B,cathepsin L and uPA in non-Hodgkin lymphoma (NHL) samples,and analyze the relationship between three genes and clinicopathological factors.Methods Real-time fluorescence quantitative RT-PCR was used to quantify the relative expression levels of cathepsin B,cathepsin L and uPA mRNA in 39 NHL patients without chemotherapy or radiotherapy and 15 patients with lymph node reactive hyperplasia.Relationship between their expression and clinico-pathological factors was analyzed.Results mRNA expression levels of cathepsin B,cathepsin L and uPA in NHL group were significantly higher than those in the control group (0.403 vs 0.128,0.209 vs 0.057,0.459 vs 0.031,all P < 0.05).The mRNA expression levels of cathepsin B,cathepsin L and uPA were correlated with each other in NHL.The mRNA expression levels of cathepsin B,cathepsin L and uPA in advanced staged NHL were markedly higher than those in early staged NHL (0.453 vs 0.341,0.204 vs 0.085,0.372 vs 0.196,all P < 0.05).mRNA levels of cathepsin B,cathepsin L and uPA were higher in NHL patients sensitive to chemotherapy than in those resistant to chemotherapy(0.401 vs 0.556,0.085 vs 0.205,0.316 vs 0.499,all P < 0.05).Conclusions The high expression of cathepsin B,cathepsin L and uPA could be detected in NHL,and their expression has a close relationship with the biological behavior characters of NHL.The dynamic examination of cathepsin B,cathepsin L and uPA may be used as clinical auxiliary diagnosis and prognosis of NHL.
5.Progress of venetoclax in treatment of acute myeloid leukemia
Journal of Leukemia & Lymphoma 2021;30(5):257-261
Venetoclax is an important breakthrough in the treatment of acute myeloid leukemia (AML) in recent years. A chemo-free treatment of inducing apoptosis drugs combined with hypomethylating agents is used in the management of AML, which brings hope of long-term survival for the elderly patients or patients who cannot tolerate intensive chemotherapy. However, there are still some patients who are resistant to venetoclax-based regimens. This article introduces the new progress of venetoclax in the treatment of AML in combination with reports at the 62nd American Society of Hematology (ASH) Annual Meeting.

Heart disease is the major disease that threaten human health. ECG is an important tool for the diagnosis of cardiac disease. As traditional ECG measurement devices have many disadvantages, a non-contact ECG measurement system was designed. With the non-contact electrode based on capacitive coupling, the signals were collected and then they were amplified and filtered. The conditioned analog signal was converted to digital data which was sent to the mobile terminal through bluetooth. Finally, the ECG data was analyzed to extract the key ECG parameters. The results showed that the precise ECG signals can be got with the non-contact electrode and the key ECG parameters can be acquired accurately.

MicroRNA is a type of endogenous noncoding small molecular RNA with a length of 19-25 nucleotides. MicroRNAs are involved in almost all key biological processes, such as cell proliferation, differentiation, apoptosis, and hematopoiesis, via repres-sion of target gene expression. Acute lymphoblastic leukemia (ALL) is the most common type of pediatric cancer. It is a heterogeneous disease with different clinical signs, morphology, immunophenotype, and cytogenetics. Currently, several microRNAs have implicated aberrant expression in ALL and play an important role in cancer initiation and development. MicroRNA expression pattern is associated with clinical feature, prognosis, and treatment. Therefore, microRNAs could act as a novel marker to help scientists learn about the pathogenesis of ALL and to provide more effective treatment options.
