Objective To explore the efficacy and safety of recombinant human anti-severe acute respiratory syn-drome coronavirus 2(anti-SARS-CoV-2)monoclonal antibody injection(F61 injection)in the treatment of patients with coronavirus disease 2019(COVID-19)combined with renal damage.Methods Patients with COVID-19 and renal damage who visited the PLA General Hospital from January to February 2023 were selected.Subjects were randomly divided into two groups.Control group was treated with conventional anti-COVID-19 therapy,while trial group was treated with conventional anti-COVID-19 therapy combined with F61 injection.A 15-day follow-up was conducted after drug administration.Clinical symptoms,laboratory tests,electrocardiogram,and chest CT of pa-tients were performed to analyze the efficacy and safety of F61 injection.Results Twelve subjects(7 in trial group and 5 in control group)were included in study.Neither group had any clinical progression or death cases.The ave-rage time for negative conversion of nucleic acid of SARS-CoV-2 in control group and trial group were 3.2 days and 1.57 days(P=0.046),respectively.The scores of COVID-19 related target symptom in the trial group on the 3rd and 5th day after medication were both lower than those of the control group(both P＜0.05).According to the clinical staging and World Health Organization 10-point graded disease progression scale,both groups of subjects improved but didn't show statistical differences(P＞0.05).For safety,trial group didn't present any infusion-re-lated adverse event.Subjects in both groups demonstrated varying degrees of elevated blood glucose,elevated urine glucose,elevated urobilinogen,positive urine casts,and cardiac arrhythmia,but the differences were not statistica-lly significant(all P＞0.05).Conclusion F61 injection has initially demonstrated safety and clinical benefit in trea-ting patients with COVID-19 combined with renal damage.As the domestically produced drug,it has good clinical accessibility and may provide more options for clinical practice.

Objective: To understand the current status of diagnosis and treatment of chronic lymphocytic leukemia (CLL) /small lymphocytic lymphoma (SLL) among hematologists, oncologists, and lymphoma physicians from hospitals of different levels in China. Methods: This multicenter questionnaire survey was conducted from March 2021 to July 2021 and included 1,000 eligible physicians. A combination of face-to-face interviews and online questionnaire surveys was used. A standardized questionnaire regarding the composition of patients treated for CLL/SLL, disease diagnosis and prognosis evaluation, concomitant diseases, organ function evaluation, treatment selection, and Bruton tyrosine kinase (BTK) inhibitor was used. Results: ①The interviewed physicians stated that the proportion of male patients treated for CLL/SLL is higher than that of females, and the age is mainly concentrated in 61-70 years old. ②Most of the interviewed physicians conducted tests, such as bone marrow biopsies and immunohistochemistry, for patient diagnosis, in addition to the blood test. ③Only 13.7% of the interviewed physicians fully grasped the initial treatment indications recommended by the existing guidelines. ④In terms of cognition of high-risk prognostic factors, physicians' knowledge of unmutated immunoglobulin heavy-chain variable and 11q- is far inferior to that of TP53 mutation and complex karyotype, which are two high-risk prognostic factors, and only 17.1% of the interviewed physicians fully mastered CLL International Prognostic Index scoring system. ⑤Among the first-line treatment strategy, BTK inhibitors are used for different types of patients, and physicians have formed a certain understanding that BTK inhibitors should be preferentially used in patients with high-risk factors and elderly patients, but the actual use of BTK inhibitors in different types of patients is not high (31.6%-46.0%). ⑥BTK inhibitors at a reduced dose in actual clinical treatment were used by 69.0% of the physicians, and 66.8% of the physicians had interrupted the BTK inhibitor for >12 days in actual clinical treatment. The use of BTK inhibitors is reduced or interrupted mainly because of adverse reactions, such as atrial fibrillation, severe bone marrow suppression, hemorrhage, and pulmonary infection, as well as patients' payment capacity and effective disease progression control. ⑦Some differences were found in the perceptions and behaviors of hematologists and oncologists regarding the prognostic assessment of CLL/SLL, the choice of treatment options, the clinical use of BTK inhibitors, etc. Conclusion: At present, a gap remains between the diagnosis and treatment of CLL/SLL among Chinese physicians compared with the recommendations in the guidelines regarding the diagnostic criteria, treatment indications, prognosis assessment, accompanying disease assessment, treatment strategy selection, and rational BTK inhibitor use, especially the proportion of dose reduction or BTK inhibitor discontinuation due to high adverse events.

After reading the article, Tracing Origin and Development of "Fenglong (ST 40) for Phlegm": Examination and Verification published in Chinese Acupuncture & Moxibustion, the authors collected the original evidences also for the effect of Fenglong (ST 40) on phlegm disorders by tracing from 9 ancient books of acupuncture and moxibustion, explored the standardized expressions of its indications and analyzed the changes of its indications. In that article, it was viewed that the effect of Fenglong (ST 40) started to be generalized in treatment of phlegm disorders since the Ming Dynasty. On contrary, we believes that Fenglong (ST 40) works on strengthening the spleen and resolving dampness for the disorders caused by the broad meaning of "phlegm/damp". Based on it, since the Ming Dynasty, the effect of Fenglong (ST 40) is extended specifically for the disorders caused by the visible sputum from the lung, the narrowing mean of "phlegm". Hence, if "Fenglong (ST 40) for phlegm" is considered as an academic point of view, it needs an adequate evidences to expound and prove.

This paper analyzes the problems existing in the current theory of divergent meridian (""), such as the unclear route of divergent meridian, the controversy in the "---" and the lack of in-depth research on the theory of "", clarifies the source and privides insights. The author analyzed the word "" by means of the four proofreading methods combined with philology method to explore the origin of " ". The divergent meridians is the remnant of the original meridians system in the bamboo and silk documents, which was put into the meridians system after being sorted out by doctors. The twelve meridians are combined in two, forming the "" point, which is located in the neck, and has a great influence on the blood circulation of the head and neck. "" point and theory can guide the differentiation of acupuncture and moxibustion, and has an important guiding significance for the treatment of empirical, emergency and head and face diseases.

OBJECTIVETo discuss the cardiac toxicities of a heat waves and ozone exposure on cardiovascular diseases (CVDs) and explore a possible mechanism.

METHODSThe incidence of ozone exposure combined with heat wave was simulated in the Shanghai Meteorological and Environmental Animal Exposure System (Shanghai-METAS). A total of 64 ApoE-/- mice, matched by weight, were randomly divided into 8 groups and exposed to heat wave conditions or ozone. The levels of creatine kinase (CK), D-lactate dehydrogenase (D-LDH), intercellular adhesion molecule 1 (sICAM-1), tumor necrosis factor alpha (TNF-α), nitric oxide (NO), endothelin-1 (ET-1), D-dimer (D2D), plasminogen activator inhibitor-1 (PAI-1) and blood lipid in plasma and heat shock protein-60 (HSP60), hypoxia inducible factor 1 alpha (HIF-1α), interleukin-6 (IL-6), C-reactive protein (CRP), superoxide dismutase (SOD), and malondialdehyde (MDA) in hearts were measured after exposure.

RESULTSThe levels of all indicators, except for SOD, increased with the ozone-only exposure. However, cardiac damage was most significant when the heat wave conditions were combined with severe ozone exposure. Moreover, the levels of CK, D-LDH, NO, PAI-1, sICAM-1, and TNF-α in plasma increased significantly (P < 0.05), and the contents of HSP60, HIF-1α, CRP, and MDA in hearts increased considerably (P < 0.05), but the activity of SOD decreased significantly. In addition, the levels of four blood lipid items remarkably increased (except the level of HDL-C which decreased significantly) with ozone exposure.

CONCLUSIONA short-term exposure to a heat wave and ozone causes severe toxic effects on the heart. Cardiac damage was most significant under combined heat wave and severe ozone exposure simulations.

Rice leaf color mutants play a great role in research about the formation and development of chloroplasts and the genetic mechanism of the chlorophyll (Chl) metabolism pathway. pgl3 is a rice leaf color mutant derived from Xiushui11 (Oryza sativa L. spp. japonica), treated with ethyl methane sulfonate (EMS). The mutant exhibited a pale-green leaf (pgl) phenotype throughout the whole development as well as reduced grain quality. Map-based cloning of PGL3 revealed that it encodes the chloroplast signal recognition particle 43 kDa protein (cpSRP43). PGL3 affected the Chl synthesis by regulating the expression levels of the Chl synthesis-associated genes. Considerable reactive oxygen species were accumulated in the leaves of pgl3, and the transcription levels of its scavenging genes were down-regulated, indicating that pgl3 can accelerate senescence. In addition, high temperatures could inhibit the plant's growth and facilitate the process of senescence in pgl3.
