OBJECTIVE To investigate the causal association between ticagrelor and risk of infection METHODS Two-sample Mendelian randomization was adopted. Genetic instrumental variables were selected based on the results of the largest genome-wide association analysis to in vivo exposure of ticagrelor and its major active metabolite AR-C124910XX. The causal associations of ticagrelor and its major active metabolite AR-C124910XX with drug indications （coronary artery disease， unstable angina pectoris， myocardial infarction， stroke and ischemic stroke）were analyzed by inverse variance weighted Mendelian randomization model as a positive control for genetic instrumental variables. The causal relationship between ticagrelor and bacterial infection， acute lower respiratory infection， bacterial pneumoniae， pneumoniae，acute upper respiratory infection and sepsis were furtheranalyzed by using this method， and the robustness of the results was assessed by using heterogeneity tests and horizontal 202002030415） pleiotropy tests. RESULTS The increase of area under the curve at steady state （AUCss） of the genetic surrogated ticagrelor significantly reduced the risk of coronary artery disease， myocardial infarction and unstable angina pectoris （P＜0.001）. AUCss genetic instrument variables of its main active metabolite AR-C124910XX failed to pass positive control. Further analysis showed that the increase of the genetic surrogated ticagrelor exposure suggestively reduced the risk of bacterial infection [OR（95%CI）＝0.80（0.65，0.99），P＝0.040] and sepsis [OR （95%CI）＝0.84（0.73， 0.98）， P＝0.023]. The results of the heterogeneity tests showed that there was no heterogeneity in the causal association of the genetic surrogated ticagrelor AUCss with bacterial infection and sepsis （P＞0.05）. The results of horizontal pleiotropy tests showed that the causal association of genetic surrogated ticagrelor AUCss with bacterial infection and sepsis had no effects on horizontal pleiotropy （P＞0.05）. CONCLUSIONS Ticagrelor has a potential role in reducing the risk of sepsis and bacterial infections.

Hepatosteatosis is characterized by abnormal accumulation of triglycerides(TG),leading to prolonged and chronic inflammatory infiltration.To date,there is still a lack of effective and economical therapies for hepatosteatosis.Oridonin(ORI)is a major bioactive component extracted from the traditional Chinese medicinal herb Rabdosia rubescens.In this paper,we showed that ORI exerted significant protective ef-fects against hepatic steatosis,inflammation and fibrosis,which was dependent on LXRα signaling.It is reported that LXRα regulated lipid homeostasis between triglyceride(TG)and phosphatidylethanol-amine(PE)by promoting ATCL and EPT1 expression.Therefore,we implemented the lipidomic strategy and luciferase reporter assay to verify that ORI contributed to the homeostasis of lipids via the regulation of the ATGL gene associated with TG hydrolysis and the EPT1 gene related to PE synthesis in a LXRα-dependent manner,and the results showed the TG reduction and PE elevation.In detail,hepatic TG overload and lipotoxicity were reversed after ORI treatment by modulating the ATCL and EPT1 genes,respectively.Taken together,the data provide mechanistic insights to explain the bioactivity of ORI in attenuating TG accumulation and cytotoxicity and introduce exciting opportunities for developing novel natural activators of the LXRα-ATGL/EPT1 axis for pharmacologically treating hepatosteatosis and metabolic disorders.

With the aging of population, the elderly (≥65 years old) cancer patients have become one of the main populations for cancer care. For inoperable locally advanced head and neck squamous carcinomas, cisplatin-based concurrent chemoradiotherapy is the first-line choice. Several large clinical studies have shown that patients under 70 years of age can still benefit from concurrent chemoradiotherapy, while it should be cautious to apply chemotherapy to patients aged 70-80 years. For elderly patients who are intolerant to cisplatin, carboplatin or other regimens with less gastrointestinal and renal toxicity should be considered. Although anti-epidermal growth factor receptor (EGFR) monoclonal antibodies combined with radiotherapy has been proved to be more effective than radiotherapy alone in total patient population, age-subgroup analysis showed limited benefit in elderly patients. The safety of immune checkpoint inhibitors in elderly patients has been validated and those with high programmed death ligand-1 (PD-L1) expression may benefit from concurrent or neoadjuvant immunotherapy, however, high-level evidence is still lacking. For patients older than 80 years, radiotherapy alone may be superior to concurrent chemoradiotherapy, and hypofractionated radiotherapy for palliative purposes can be safely used in this population.

Radiotherapy is an essential part of comprehensive treatment, as well as a radical treatment for head and neck cancer (HNC). The COVID-19 has continued so far, imposing a great impact on cancer care. Since conventional fractionated radiotherapy (CFRT, 2 Gy/F) requires as long as more than six weeks of treatment time, a huge challenge for epidemic control is created for both hospitals and patients. Hypofractionated radiotherapy (Hypo-RT) may be more suitable than CFRT for patients during pandemic by increasing the fraction size, thus reducing fraction number and treatment duration. Early studies have explored the application of Hypo-RT in HNC in palliative setting, which partially proved its safety and effectiveness. Recently, the efforts have been made in definitive treatment using hypofractionated regimen, as well as its combination with systemic treatment and immunotherapy. Indeed, regarding the pandemic of COVID-19, Hypo-RT has been recommended by several expert consensus in the HNC. In this review, relevant research progress was summarized and clinical implication of Hypo-RT in COVID-19 pandemic era was discussed.

OBJECTIVE：To excavate and evaluate ADR signals of SGLT 2 inhibitors as canagliflozin ，dapagliflozin and empagliflozin，and to provide reference for rational drug use in the clinic. METHODS ：The proportional reporting ratio （PRR）and reporting odds ratio （ROR）were used to find the adverse drug reactions （ADR）signal of SGLT 2 inhibitors as canagliflozin ， dapagliflozin and empagliflozin from the second quarter of 2013 to the third quarter of 2020 in the US FDA Adverse Event Reporting System （FAERS）. The basic information （including gender ，age，reporting year ，reporting country ，severe ADR ）and safety warning signals of corresponding patients in ADR report were analyzed. RESULTS ：Among 6 029 375 ADR reports ，SGLT2 inhibitors of 43 807 ADR reports were concomitant and suspected drugs ；there were 19 301 ADR reports of canagliflozin ，10 960 ADR reports of dapagliflozin ，13 546 ADR reports of empagliflozin. Except for the ADR patients with unknown gender and missing age ，the gender distribution of the included reports was balanced ，mainly in the range of 50-75 years old. The reporting year was mainly in 2018，and the main reporting country was the United States ，with“hospitalization or prolonged hospitalization ” as the main serious ADR. A total of 573 ADR signals were obtained ，involving 26 systems，mainly focusing on metabolic and nutritional diseases ，endocrine disorders ，kidney and urinary system disease ，infection and invasion diseases ，etc. The results showed that there were 14 main ADR signals in the top 10 ADR of canagliflozin ，dapagliflozin and empagliflozin. The strongest ADR signals of dapagliflozin and empagliflozin were ketoacidosis （PRR＝119.64/140.11，95％CI lower limit of ROR ＝148.28/ 178.78）and fungal infection （PRR＝47.76/34.77，95％ CI lower limit of ROR ＝50.69/36.28）；except above signals in addition ， toe amputation （PRR＝489.79，95％CI lower limit of ROR ＝520.15）and osteomyelitis （PRR＝61.42，95％CI lower limit of ROR＝65.38）were strong in the ADR signals of canagliflozin. CONCLUSIONS ：SGLT2 inhibitors have a higher security risk in metabolic and nutritional diseases ，endocrine disorders ，kidney and urinary system ，and infection and intrusion diseases. Dapagliflozin，canagliflozin and empag liflozin are prone to cause ADR such as ketoacidosis and fungal infection ，while canagliflozin is easy to cause ADRs such as toe amputation and osteomyelitis.

OBJECTIVE：To excavate the ADR signals of rivaroxaban and provide reference for its safe and rational use in clinic. METHODS ：Based on FDA adverse event reporting system （FAERS），the ADRs of rivaroxaban reported from September 2008 to December 2020 in FDA ’s Open Data Program were mined using ratio of reports to odds （ROR）and proportional report ratio （PRR）. The related ADRs were analyzed ，and the corresponding system organ classification （SOC）was mapped. At the same time，the basic information such as gender ，age and indications of the patients were statistically reported. RESULTS & CONCLUSIONS：Among 9 373 236 ADR reports extracted ，102 027 ADR reports with rivaroxaban as concomitant and suspected drug were obtained ；883 ADR signals were mined ，involving 27 systems. Among 102 027 reports，the proportion of female patients （41 294 cases，40.47％）was similar to that of male patients （41 071 cases，40.26％）. The patients were mainly ＞50 to 75 years old（29 261 cases，28.68％）and ＞75 years old （21 470 cases，21.04％）. The reporting year was mainly in 2018（18 446 cases， 18.08％）；main reporting country was the United States （75 390 cases，73.89％）；there were 35 046 cases（34.35％）of severe ADR reports ，mainly involving hospital or prolonged hospital stay. The SOC of rivaroxaban ADR singal mainly focused on diseases of the blood and lymphatic system ，vascular diseases ，various types of examination and nervous system diseases. Among top 20 preferred terms of ADRs with the highest frequency ，except for pulmonary embolism ，acute kidney injury and atrial fibrillation ，the rest were mainly bleeding related ADRs ，of which intracranial hemorrhage was the more seriou s ADR. Intracranial hemorrhage may occur when rivaroxaban is used for the prevention of atrial fibrillation and cerebrovascular accidents ， and pulmonary embolism may occur when rivaroxaban is used for the prevention of pulmonary embolism ，（deep）venous thrombosis and thrombosis. Great importance should be paid on it.

OBJECTIVE：To provide evidence-based reference for c linical drug selection and decision by rapidly evaluating the effectiveness，safety and economy of treprostinil in the treatment of pulmonary arterial hypertension （PAH）. METHODS ：Retrieved from Chinese and English database such as PubMed ，Embase，Web of Science ，the Cochrane Library ，Epistemonikos，HTA database（University of York ），CNKI and Wanfang databases ，included the health technology assessment （HTA）report，systematic/ Meta-analysis and pharmacoeconomic evaluation of treprostinil compared with placebo or other drugs in the treatment of PAH. The search time limit is from the construction of the database to May 1st，2020. HTA checklist ，AMSTA and CHEERS were applied to evaluate the quali ty of the literatures about HTA ，systematic review/Meta-analysis analysis a nd pharmacoecono mic evaluation and the inclusion studies was analyazed by descriptive summary. RESULTS：A total of 18 literatures were included ，involving 1 HTA report ，12 systematic review/Meta-analysis ，5 pharma- coeconomic studies. The analysis results of effectiven- ess mail： showed that compared with placebo ，treprostinil could signifi- cantly increase 6-MWD while decrease Borg dyspnea score of PAH p atients（P＜0.05），but had no significant effect on mortality，the rate of clinical deterioration ，WHO functional grading ，the rate of hospitalization ，mPAP，PVR，cardiac index and mRAP（P＞0.05）. In addition ，compared with placebo combined with endothelin receptor antagonist and/or phosphodiesterase inhibitors，oral administration of treprostinil combined with endothelin receptor antagonist and/or phosphodiesterase inhibitors could extend 6-MWD significantly. Compared with riociguat ，treprostinil could significantly reduce Borg dyspnea score of patients. The analysis results of safety displayed that ，although the incidence of drug withdrawal due to can ’t tolerate ADR increased in patients receiving treprostinil ，there was no significant difference in the incidence of serious adverse events compared with placebo or other treatments，and it was better tolerated when administered by inhalation or intravenous injection. The analysis results of pharmacoeconomic studies showed that ICER of treprostinil was higher than the willingness payment threshold ，although the willingness payment threshold was different in different countries and different payers. CONCLUSIONS ：Treprostinil treatment is effective for PAH. Patients may stop taking it due to can ’t tolerate ADR ，but the risk of serious adverse events are not increase. Although the price is high ，it is still an important alternative for PAH patients with clinical progress or poor prognosis.

OBJECTIVE: To identify mitochondrial gene variants associated with statin-induced myalgia in Chinese patients with coronary artery disease (CHD). METHODS: This study was conducted in a cohort of 403 patients with CHD receiving rosuvastatin therapy, among whom 341 patients had complete follow-up data concerning myalgia and 389 patients had documented measurements of plasma creatine kinase (CK) level. All these patients underwent genetic analysis using GSA chip for detecting mitochondria gene variants associated with myalgia. A logistic regression model was used to assess the association between 69 mitochondrial single-nucleotide polymorphisms (SNPs) and myopathy in 341 patients. The impact of these mutation sites on CK levels in 389 patients was evaluated by linear regression analysis. RESULTS: G12630A variant was identified to correlate with an increased risk of myalgia in CHD patients (OR: 8.689, 95% CONCLUSIONS Mitochondrial G12630A variation is associated with statin-induced myalgia in patients with CHD, indicating the necessity of different treatment strategies for patients who carry this risk allele.
