Objective:To explore and compare the clinical efficacy of lyophilized recombinant human brain natriuretic peptide (Lrh-BNP) and dobutamine (Dob) in the treatment of patients with acute heart failure (AHF) and impacts on the plasma galectin (Gal)-3,Cystatin C (CysC) and endothelin (ET-)-1 levels.Methods:114 cases of patients with AHF in our hospital from February 2015 to February 2017 were selected as the research objectives and randomly divided into two groups.Dob group was treated by Dob,while Lrh-BNP group was treated by Lrh-BNP.The cardiac function parameters,plasma Gal-3,CysC,ET-1 levels before and after treatment,clinical comprehensive efficacy and incidence of adverse reactions were compared between two groups.Results:The FS,LVEF levels of both groups at 72 hours after treatment were significantly higher than those before treatment (P<0.01),but the LVEDD,plasma Gal-3,CysC,ET-1 levels were obviously decreased (P<0.01),the index mentioned above of Lrh-BNP group improved more significantly than those of the Dob group(P<0.01).The overall effective rate of Lrh-BNP group was 89.5 %,which was significantly higher than that of the Dob group (73.7%,P<0.05).No significant difference was found in the incidence of adverse reaction between two groups(P>0.05).Conclusion:Lyophilized recombinant human brain natriuretic peptide was more effective in the treatment of AHF than Dobutamine with equal safety,which might be related to the decrease of plasma Gal-3,CysC,ET-1 levels.

In recent years, neurotoxicity caused by traditional Chinese medicine (TCM) has frequently occurred and has become one of the important factors restricting the development and application of TCM. TCM contains active components and its dosage-effect relationship is the key to determine its pharmacological activity and toxic effects. Among them, the endogenous toxic components include alkaloids, glycosides, diterpenoids, animal and plant toxic proteins and heavy metals, and so on; exogenous toxic components mainly refer to some harmful elements and pesticide residues during the cultivation, processing, transportation and storage of medicinal materials that are not synthesized by themselves. Effect on the processes such as oxidative stress, inflammation, ion exchange, and energy metabolism may be important mechanisms of TCM-induced neurotoxicity. Neural cells, myelin cells, axons and neurotransmitter systems are common targets of TCM-induced neurotoxicity. In the future, we can use modern research methods and big data mining means to establish a safety evaluation mode of “toxic symptoms-poisoning dose-toxic original agent-detoxification scheme” with the basic component group of toxic substances as the core, so as to provide support for development and clinical intervention of neurotoxic traditional Chinese medicine.

Objective:To evaluate the efficacy and safety of nimotuzumab combined with definitive radiotherapy in the treatment of inoperable locally advanced oral and maxillofacial squamous cell carcinoma.Methods:A total of 33 patients with inoperable locally advanced oral and maxillofacial squamous cell carcinoma admitted to the Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine from March 2015 to December 2019 were retrospectively selected as the research objects. The treatment regimen was all targeted therapy (nimotuzumab) combined with definitive radiotherapy, with or without chemotherapy, and the efficacy and safety of the treatment were analyzed. The primary endpoints were optimal response and overall survival (OS) , and the secondary endpoints were optimal duration of response (DOR) and progression-free survival (PFS) . The survival curve was drawn using the Kaplan-Meier method, the survival rate of the patients was analyzed, and the related adverse reactions were counted.Results:Of the 33 patients, there were 20 cases of complete remission (CR) , 5 cases of partial remission (PR) , 5 cases of stable disease (SD) , 2 cases of progressive disease (PD) , and 1 case could not be evaluated. The objective response rate was 75.8% (25/33) , and the disease control rate was 90.9% (30/33) . The mean OS of all cases was 54.5 months, and the 5-year OS rate was 57.0%. The mean DOR of the overall cases was 57.2 months, and the 5-year DOR rate was 64.4%. The mean PFS of the overall cases was 54.4 months, and the 5-year PFS rate was 59.8%. The 5-year OS rates of CR, PR and SD patients were 83.6%, 20.0% and 0 ( χ2=20.07, P<0.001) , the 5-year DOR rates were 85.0%, 20.0% and 0 ( χ2=16.89, P<0.001) , and the 5-year PFS rates were 84.0%, 20.0% and 0 ( χ2=15.91, P<0.001) . The OS, DOR and PFS of patients with CR were significantly better than those of patients with PR and SD (all P<0.05) . The 5-year OS rates of patients with oropharyngeal cancer and oral cancer were 62.5% and 40.6% ( χ2=1.67, P=0.197) , the 5-year DOR rates were 73.3% and 44.0% ( χ2=1.34, P=0.247) , and the 5-year PFS rates were 68.8% and 40.9% ( χ2=1.13, P=0.289) , with no statistically significant differences, but oropharyngeal cancer patients still showed a certain advantage. Common adverse reactions included oral mucositis and hematological toxicity, most of which were grade 1-2. Two (6.1%) patients had rash, and two (6.1%) patients had nausea and vomiting, which were considered to be related to nimotuzumab. All adverse reactions were relieved after symptomatic treatments. Conclusion:For patients with locally advanced oral and maxillofacial squamous cell carcinoma who are not suitable for surgery, the choice of nimotuzumab combined with definitive radiotherapy has a relatively satisfactory efficacy and survival rate, with good safety and high clinical value.
