Since the outbreak of coronavirus disease 2019 (COVID-19), the National Health Commission and the expert group of the army have formulated multiple versions of diagnosis and treatment scheme, and drug therapy regimens have become a research hotspot for scholars. Meanwhile, some clinicians found that acute kidney injury (AKI) was an important risk factor in the death of patients with severe COVID 19. The mechanism of AKI in COVID-19 patients is still unclear and the causes may be related to virus infection or drug toxicity. Drug-related AKI directly affects the clinical treatment options and the patient's long-term prognosis. This article targets interferon-α, lopinavir / ritonavir, ribavirin, chloroquine phosphate, abidol and tocilizumab. This article reviewed potential novel coronavirus pneumonia treatment-related AKI, characteristics of the clinical cases, and mechanisms of renal toxicity, to provide a reference for clinical treatment.

OBJECTIVETo evaluate the objectivity and comprehensiveness of Response Evaluation Criteria of Traditional Chinese Medicine for Solid Tumor (Draft, REC-TCM-ST) in application of Chinese medicine therapeutic effect in patients with advanced non-small cell lung cancer (NSCLC).

METHODSA retrospective clinical research was used in 104 NSCLC patients in stages of III-IV, 53 cases were in Chinese medicine (CM) group and 51 cases were in Western medicine (WM) group. The therapeutic effect of the two groups was evaluated with both REC-TCM-ST and Response Evaluation Criteria in Solid Tumor (RECIST). Kaplan-Meier method was used to analyze the survival time. Kappa test method was used to test the consistency of the two kinds of evaluation results.

RESULTSAccording to REC-TCM-ST, the effective rate on relieving tumor mass in the CM group was significantly lower than that in the WM group (P<0.05), but there was no significant difference in tumor-mass stable rate (P>0.05); the symptom of weakness in the CM group was improved significantly, indicating better therapeutic effect than that in the WM group (P<0.01). Karnofsky score in the CM group was significantly better than that in the WM group (P<0.01). In terms of survival conditions, the median survival time and the survival rate of 6 months, 1 year and 2 years of the CM group were higher than the WM group. The total effective rate was 9.62%, and the total stable rate was 72.12% for 104 cases according to RECIST; while the total effective rate was 34.62%, and the total stable rate was 84.62% according to REC-TCM-ST, thus there were significant differences between the results of the two criteria (P<0.01), and there was also some consistency between them, but not satisfactory.

CONCLUSIONSREC-TCM-ST was used to evaluate the therapeutic effect of CM in the treatment of advanced NSCLC, which shows that its evaluation results can better reflect the advantages and disadvantages of CM, and the effectiveness of CM is more objective and comprehensive than RECIST, so REC-TCM-ST is worthy of further improvement and clinical expansion.

PURPOSE: This study applied the Q method to identify and describe the various types of nurse perceptions that are crucially associated with their engagement in evidence-based nursing (EBN). METHODS: The study participants were nurses at a medical center and a regional teaching hospital. A series of Q sorts was performed by nurses to subjectively rank the Q statements. Q statements were constructed based on the literature related to EBN adoption by nurses and face-to-face interviews. RESULTS: A total of 60 participants were invited to rank 44 Q statements related to EBN. Factor analysis was conducted on the rankings of the Q statements. The following are the five prominent shared perspectives: (1) emphasized the obstacles to evidence searching and reading ability; (2) emphasized the organizational promotive strategies; (3) emphasized the available supportive resources; (4) emphasized the significance of EBN; and (5) emphasized the evidence-searching ability and external incentives. The five identified groups of perspectives can enhance hospital administrators to acknowledge the barriers and incentives associated with EBN practices. CONCLUSION: The exploration of clustering nurses' perceptions may facilitate the development of customized strategies to enable more appropriate training.

Kinases play crucial roles in the life of cell. Their functional abnormity usually leads to many human major diseases including tumors. The prospecting of ATP-competitive small-molecule kinase inhibitors targeting kinases of therapeutic interest has become the focus of researches. Due to the high conservation of the catalytic domain of kinases, the selectivity of kinase inhibitors is poor in general. However, along with the development of structural biology and computer-aided drug design, great progress in the research of selective, ATP-competitive kinase inhibitors has been achieved in recent years. In this account, the review has been made on the development of the design of selective kinase inhibitors.

This study aims to analyze the molecular epidemiological characteristics of HIV-1 strains prevailing among men who have sex with men (MSM) in Beijing, China. The pol gene fragments from 250 newly diagnosed HIV-1-infected MSM individuals during 2006-2010 in Beijing were amplified by RT-nested PCR, sequenced, and phylogenetically analyzed. HIV-1 pol gene from 189 individuals were amplified and analyzed; 81 (42. 9%), 3 (1. 6%), 2 (1.0%), 88 (46. 6%), and 15 (7.9%) individuals were infected with HIV-1 subtypes B, B', C, CRF01_AE, and CRF07_BC, respectively. The subtypes B and CRF01_AE could both be grouped into two clusters, and CRFO7_BC strains shared high homology and were presumed to originate from a common ancestor. The HIV-1 circulating in MSM in Beijing had a lower genetic diversity than in heterosexuals. The HIV-1 epidemic (2006-2010) in MSM in Beijing was actually a rapid spread of HIV-1 CRF01 AE and B, or rather native strains of the two viruses.

OBJECTIVETo study the effects of beta-asarone on expression of immediately early gene c-fos in kindling epilepsy rat brain.

METHODThe rats were randomly divided in to beta-asarone groups (200, 100, 50 mg x kg(-1) x d(-1)), difetoin control group (36 mg x kg(-1)) and model group. The remedy was administered orally. The effects were observed in kindling epilepsy model induced by penicillin, then the expression of c-fos were determined by western blot (hippocampus) and immunohistochemical techniques (cortex).

RESULTBeta-asarone could significantly increase the expression of c-fos in kindling epilepsy rat brain, and show its quantity-effect relation. The expression of c-fos in hippocampus was (1139.45 +/- 155.56), (1109.56 +/- 134.03), (1103.73 +/- 235.82) CNT x mm2 in beta-asarone groups, 920.54 +/- 203.20 in model control group, and 1106.26 +/- 186.24 in difetoin group, respectively. The number of c-fos positive cell was 87.1 +/- 2.2, 76.3 +/- 1.3 and 59.9 +/- 1.3 in beta-asarone groups, 39.3 +/- 2.6 in model control group, and 95.2 +/- 1.1 in difetoin group, respectively.

CONCLUSIONBeta-asarone can obviously increase the expression of c-fos in epilepsy rat brain. It is one of important response to epilepsy.
