BACKGROUND:To improve the survival rate of transplanted hematopoietic stem cells, dynamic monitoring of plasma content of human cytomegalovirus (HCMV) and rapid screening of early active HCMV infection in hematopoietic stem celltranplantation recipients, thus to guide the clinical medication, is preferred. OBJECTIVE:To evaluate the usefulness of fluorescence quantitative PCR assay for early detection of HCMV activation after hematopoietic stem celltransplantation. METHODS:Real-time fluorescence quantitative PCR assay was applied for HCMV monitoring in 656 blood samples from 41 hematopoietic stem celltranplantation recipients and 60 control blood samples. RESULTS AND CONCLUSION:In 656 blood samples, 96 samples were positive, and the HCMV DNA copies ranged from 5.0×102 to 1.0×107 IU/mL. Timely initiation of therapy resulted in the rapid clearance of DNA-viraemia but it recurrenced in short time by drug-resistent. Two cases from 12 postive recipients died from HCMV infection. The quantitative detection of HCMV DNA by real-time PCR is a rapid method for monitoring HCMV infection and the early diagnosis in patients after hematopoietic stem celltransplantation.

Over the past decade, the management model of cancer patients has gradually shifted to individual mode based on molecular mutation detection. Epidermal growth factor receptor (EGFR) gene mutation is an important driving factor in non-small cell lung cancer (NSCLC). Compared with traditional chemotherapy, EGFR-targeted therapy shows significant safety and efficacy. However, not all patients with EGFR mutations are eligible for EGFR-targeted therapy, and different types of mutations often indicate different clinical outcomes, such as the sensitive mutations EGFR 19-Del, L858R, and the resistance mutation. In addition, the third-generation TKI drugs Osimertinib (AZD9291) and Rociletinib (CO-1686) have been developed to further benefit patients with primary TKI resistance caused by T790M mutation of EGFR. Therefore, detection of the EGFR mutation status of patients before treatment, and continuously monitoring the mutation of drug resistance genes during the treatment process is useful for the management of targeted drugs in NSCLC patients. In recent years, the rapid development of "liquid biopsy" technology has made it possible to use non-invasive methods to monitor drug resistance mutations in real time. In this paper, we reviewed the clinical application of various non-invasive detection techniques for EGFR mutations in NSCLC in different liquid samples.

Depression is a mental illness characterized by significant and lasting depression. Recent studies have found that cholecystokinin, as a small brain-gut peptide molecule, is widely distributed in the central nervous system and enteric nervous system. In order to further clarify the relationship between CCK and the pathogenesis of depression, this article reviews the effect of CCK in depression, including HPA axis, synaptic function and circuit mechanism, etc.

The ongoing pandemic coronavirus disease 19 (COVID-19) remains a significant issue for global health, economics, and society. In order to balance epidemic control and economic recovery, many countries have successively announced the gradual relaxation of some lockdown restrictions. Hospitals and medical staff constitute the backbone in this war against COVID-19. In response to this serious situation, many hospitals went into emergency and impaired healthcare access to patients with conditions other than COVID-19. Therefore, gradually promoting hospital operations and functions back to the new normal is important, especially when this outbreak has been effectively controlled. In this study, we introduce existing and potential problems that could seriously affect people's health. Additionally, we propose that an especial transition phase between the emergency and regular modes of hospitals can be well adapted to the current situation.

Objective To investigate the efficacy and mechanism of action of Compound Chaijin Jieyu Tablets (复方柴金解郁片, CCJJYT) in rats with insomnia complicated with depression. Methods Seventy-two Sprague-Dawley rats were randomly assigned into eight groups: the control, chronic unpredictable mild stress (CUMS), sleep deprivation (SD), CUMS + SD, positive drug (venlafaxine hydrochloride + diazepam), CCJJYT high-dose (CCJJYT˗2×), medium-dose (CCJJYT˗1×), and low-dose (CCJJYT˗0.5×) groups, with nine rats in each group. Depression-like behavior was evaluated by body weight, food intake, and behavioral tests such as the sucrose preference test (SPT), open field test (OFT), forced swimming test (FST), and pentobarbital-induced sleep test (PST). Hematoxylin-eosin (HE) staining and Golgi-Cox staining were used to observe changes in pathological tissue and synaptic morphology, respectively. Enzyme-linked immunosorbent assay (ELISA) was used to detect the contents of orexin-A and acetylcholine. The expression levels of orexin receptor 1 (OXR1), melatonin receptor 1 (MT1A), melatonin receptor 2 (MT1B), acetylcholinesterase (AChE), and choline acetyltransferase (ChAT) were detected by immunohistochemistry and Western blot. Results In the present study, rats in the model group showed significant behavioral changes as well as a reduction in hippocampal dendritic branch length and synaptic number, along with increasing the content of orexin A and acetylcholine (P< 0.05), and altered expression levels of OX1R, MT1A, MT1B, ChAT, and AChE in the hippocampus and prefrontal cortex after modeling (P < 0.05). CCJJYT can improve depressive insomnia behavior and synaptic plasticity of rats (P < 0.05), which is similar to that of the positive drug group. It can also decrease the content of orexin A and acetylcholine, and reduce the expression levels of OXR1 and ChAT in hippocampus and prefrontal cortex (P < 0.05), and increase the expression levels of MT1A, MT1B, and AChE proteins (P < 0.05). Conclusion CCJJYT has good antidepressant and insomnia effects, probably through the regu-lation of orexin-A, melatonin, and acetylcholine content in hippocampus and prefrontal cortex of rats, improving synaptic plasticity and thus exerting antidepressant and insomnia effects.
