RESUMEN

AIM: To investigate the effect of CDAG208A gene polymorphism on the efficacy and safety of gemcitabine in the first-line treatment of lung squamous cell carcinoma. METHODS: Sixty-five first-line treated patients with locally advanced or metastatic lung squamous cell carcinoma in The First Affiliated Hospital of Wannan Medical College hospital were screened. Group A included 31 patients tested with the GG (wild homozygous) CDAG208A gene, and group B included 34 patients without testing. All patients received gemcitabine plus platinum chemotherapy for at least 2 cycles. The efficacy and safety were evaluated following the RECIST 1.1 standard and the NCI-CTC 5.0 standard, respectively. The primary study endpoint was progression-free survival (PFS), overall survival (OS) and the secondary study endpoints included objective effective rate (ORR), disease control rate (DCR), adverse reactions, and influencing factors of PFS. RESULTS: The results showed that the DCR was 74.5% and 50% in group A and group B, respectively (P=0.045); mPFS was 6.1 months and 5.0 months in group A and group B, respectively (P=0.034); and the mOS was 13.3 months and 12.0 months in group A and group B, respectively, and there was no statistical difference (P=0.388). The number of cases of grade III-IV neutropenia in group A and group B was 2 and 10, respectively (P=0.017); grade III-IV neutropenia was an independent prognostic factor affecting patients with PFS (P=0.045); the group with unknown G208A gene status was more likely to develop grade III-IV neutrophils (P= 0.029). The AUC of CDA-G208A gene predicting neutropenia caused by gemcitabine chemotherapy was 0.756. CONCLUSION: Non-GG type of CDAG208A gene can reduce the metabolic rate of gemcitabine in the body and cause neutropenia after chemotherapy. In severe cases, it can indirectly reduce the clinical efficacy of gemcitabine. The detection of CDA-G208A gene status before treatment can predict the neutropenia caused by gemcitabine chemotherapy.

RESUMEN

OBJECTIVE To evaluate the efficacy, safety and cost-effectiveness of semaglutide in the treatment of type 2 diabetes mellitus (T2DM), and to provide reference for clinical drug use. METHODS Rapid health technology assessment was adopted. Retrieved from PubMed, Embase, Cochrane Library, Web of Science, CNKI, Wanfang database, CBM, domestic and foreign HTA official websites, HTA reports, systematic evaluation/meta-analysis and pharmacoeconomic studies about semaglutide in the treatment of T2DM were collected during the inception to May 1st, 2022. After data extraction and quality evaluation, descriptive analysis was performed on the results of included studies. RESULTS A total of 22 pieces of literature were included, involving 7 meta-analyses and 15 pharmacoeconomic studies. In terms of efficacy and safety, semaglutide showed significant advantages in controlling glycated hemoglobin (HbA1c), fasting blood glucose, postprandial mean glucose, body mass index and achieving a target of glycosylated hemoglobin level <7%; also, there was no increased risk of hypoglycaemia or the incidence of serious adverse effects, but the risk of gastrointestinal adverse effects was significantly higher than other interventions. In terms of cost-effectiveness, results of foreign studies showed that semaglutide was more cost-effective, compared with other glucagon-like peptide-1 receptor agonists, sodium-glucose transporter protein 2 inhibitors, dipeptidyl peptidase-4 inhibitors. Research based on the perspective of China’s health system showed that semaglutide had a clear cost-effectiveness advantage over dulaglutide when using GDP per capita in 2020 (72477 yuan) as the payment threshold. CONCLUSIONS The semaglutide has excellent efficacy and good safety for the treatment of T2DM, with cost-effectiveness advantages over a number of drugs, but attention should be paid to the occurrence of gastrointestinal adverse effects.

RESUMEN

Currently, the corona virus disease 2019 was spreading globally, and more than 167.5 million confirmed cases worldwide. The new corona virus was highly contagious. The human body would have respiratory symptoms, fever, severe respiratory syndrome, organ failure, and even death after being infected with the virus. At present, there was no specific treatment for COVID-19. Most of the treatments were symptomatic and supportive treatment, and the prognosis was poor. Mesenchymal stem cells could not only repair damaged lung tissue, but also regulate immunity and anti-inflammatory effects, and had good clinical application prospects. We will review the application of MSCs in the treatment of COVID-19 for the reference of colleagues.

RESUMEN

Hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide, and it has diverse etiologies with multiple mechanisms. The diagnosis of HCC typically occurs at advanced stages when there are limited therapeutic options. Hepatocarcinogenesis is considered a multistep process, and hepatic macrophages play a critical role in the inflammatory process leading to HCC. Emerging evidence has shown that tumor-associated macrophages (TAMs) are crucial components defining the HCC immune microenvironment and represent an appealing option for disrupting the formation and development of HCC. In this review, we summarize the current knowledge of the polarization and function of TAMs in the pathogenesis of HCC, as well as the mechanisms underlying TAM-related anti-HCC therapies. Eventually, novel insights into these important aspects of TAMs and their roles in the HCC microenvironment might lead to promising TAM-focused therapeutic strategies for HCC.

RESUMEN

AIM: To study the polymorphism distribution of methylenetetrahydrofolate reductase (MTHFR) and methionine synthase reductase (MTRR) genes and their influence on serum homocysteine (Hcy) concentration. METHODS: A total of 148 patients diagnosed with ischemic stroke from November 2020 to February 2021 in Yijishan Hospital of Wanan Medical College were selected for the study, and patients were typed for MTHFR 677C/T and MTRR 66A/G genes using fluorescent staining in situ hybridization technique. Serum Hcy concentrations were measured in 21 patients using a circulating enzyme assay. The distribution of MTHFR 677C/T and MTRR 66A/G gene polymorphisms were analyzed, and the differences in serum Hcy concentrations between patients with different genotypes were compared. RESULTS: The mutation rates of MTHFR 677C/T and MTRR 66A/G genes were 42.57% and 26.01%, respectively, and no significant differences in gene distribution frequencies were observed between men and women (P>0.05). The mean Hcy serum concentration was (16.04±4.34) μmol/L in 21 patients, including 8 patients (38.10%) with 0.05). CONCLUSION: MTHFR gene polymorphisms can affect serum Hcy concentrations. The MTHFR genotyping can be considered for individualized folic acid supplement. This conclusion should be further verified by expanding the clinical sample size.

RESUMEN

AIM: To investigate the effects and quantitative relations of co-administering probenecid OF different dosages on pharmacokinetics of cefaclor in rabbits and approach the possible mechanisms involved as well. METHODS: Monitor plasma and urine cefaclor concentrations. 24 male rabbits were randomly divided into 4 groups by Cefaclor 50 mg·kg-1,Cefaclor50 mg·kg-1+Probenecid 100 mg·kg-1,Cefaclor 50 mg·kg-1+Probenecid 250 mg·kg-1 and Cefaclor 50 mg·kg-1+Probenecid 625 mg·kg-1.Blood and urine samples were collected according to the regular time schedule after intragastric administration. The concentration of cefaclor in blood and urine were determined by HPLC. Pharmacokinetic parameters were calculated by DAS (Drug and Statistical) software. Measur plasma protein-binding rate of cefaclor. The experimental groups and drug dosage were same as described above. The blood sample was drawn at 1 hour after administration,and the protein-binding rate of cefaclor was determined by equilibrium dialysis. RESULTS: Within the dosages of probenecid ranged from 0-250 mg·kg-1,T1/2ka,Tmax,Cmax and AUC of cefaclor increased in accordance with increasing dosage of co-administering probenecid while CL/F and Vd/F were decreased(P<0.01); However,when the dosage of co-administering probenecid was 625 mg·kg-1,Cmax of cefaclor strikingly decreased(P<0.01),while AUC and CL/F maintained at the levels of those with probenecid250 mg·kg-1.In this experiment, urinary excretive peak time of cefaclor in its prototype pos tponed gradually,biological half life prolonged and urinary excretive accumulation percentage decreased obviously(P<0.01).To the dosages of probenecid ranging from 0-250 mg·kg-1,protein-binding rate of cefaclor decreased notably(P<0.01)going with increasing dosages of co-administration probenecid; While the dosage of co-administration probenecid reached 625 mg·kg-1,the protein-binding rate of cefaclor corresponded to that of cefaclor 50 mg·kg-1 without probenecid (P<0.01).CONCLUSION: Co-administering probenecid can strikingly change pharmacokinetics of cefaclor and the influential degree of pharmacokinetics parameters is dependent on dosages of probenecid used in the experiment. Biological half life prolongs and urinary excretive accumulation percentage of cefaclor decreases obviously.
