RESUMEN
OBJECTIVE To explore and analyze the adverse drug event (ADE) signals of darolutamide and provide a reference for its clinical safe use. METHODS ADEs related to darotamide were collected based on the US FDA adverse event reporting system (FAERS) database from the third quarter of 2019 to the third quarter of 2022. Data mining and analysis were conducted by the report odds ratio (ROR) and proportional reporting ratio (PRR) methods. RESULTS A total of 565 ADE reports related to darolutamide were extracted, 356 ADE reports about darolutamide as the primary suspected drug were included, 38 ADE signals with darolutamide as the primary suspected drug were excavated, involving 15 system organ class (SOC), mainly concentrated in patients over 65 years old. The SOC of darotamide ADE signal mainly focused on various examinations, systemic diseases and various reactions at the administration site, benign/malignant tumors or those with unknown nature (including cystic and polypoid), kidney and urinary system diseases. A total of 13 ADE signals not mentioned in the instructions included increased prostate-specific antigen, dysphagia, cognitive impairment, erectile dysfunction, rhabdomyolysis, gynecomastia and decreased platelet count, etc. CONCLUSIONS When using darolutamide, in addition to ADE in the drug instruction, we should pay close attention to potential ADE, such as increased prostate-specific antigen, rhabdomyolysis, gynecomastia and decreased platelet count, so as to avoid drug withdrawal or organ damage caused by ADE.
RESUMEN
Objective:To explore the expression of peptidyl prolyl cis-trans isomerase (Pin1) activity in peripheral blood of patients with rheumatoid arthritis (RA) and the value and correlation of T helper cell 17/regulatory cells (Th17/Treg) cells, and to analyze the effect and influence of all-transretinoic acid (ATRA) on it.Methods:① Comparing the difference of Pin1 expression and absolute counts of Th17 and Treg between RA patients before and after treatment and healthy control group, Kruskal-Wallis rank sum test was used for analysis. ② To analyze the correlation between the expression of Pin1 and its general data, activity indicators [such as erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and disease activity score 28 joints (DAS28) scores], Th17, Treg and some cytokines in RA patients, and to use Pearson and Spearman correlation tests. ③ To analyze the difference of Pin1 expression and Th17/Treg in peripheral blood of RA patients treated with low-dose all-trans retinoic acid (10 mg twice a week) and traditional immunosuppressants such as hydroxychloroquine for 3 months respectively. Mann-Whitney U test was used for comparison between the two groups, and the difference was statistically significant with ( P<0.05). Results:① The activity of Pin1 in peripheral blood of the newly treated group of RA was [13.62(9.16, 19.42)] higher than that of the healthy control group [8.97(7.62, 11.45)]( Z=42.82 , P<0.05), and Th17 was [18.28(12.76, 24.08)] higher than that of the healthy control group [6.04(4.96, 4.96)]( Z=48.83 , P<0.05). Treg [11.06(5.31, 21.87). It was lower than that of healthy control group [40.41(24.33, 48.52)]( Z=42.21 , P<0.05). ② the activity of Pin1 in peripheral blood of RA patients was positively correlated with CRP, the number of involved joints, DAS28 score, interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) ( r=0.396, P<0.05; r=0.683, P<0.05; r=0.466, P<0.05; r=0.315, P<0.05; r=0.416, P<0.05). ③ Compared with the newly treated RA group, the activity of Pin1 [6.94(5.96, 8.77), Z=42.82 , P<0.05] and Th17 7.38 decreased [7.38(3.85, 11.21), Z=48.83 , P<0.05], while Treg [40.41 (17.77, 33.47)] increased ( Z=42.21 , P<0.05). ④ Compared with the traditional medicine group, Treg [28.9(21.73, 37.36)] was higher in the retinoic acid group, and the difference was statistically significant ( Z=-2.683 , P<0.05). The activity of Pin1 was [6.23(5.58, 8.75)], but there was no statistical significance ( Z=-1.622 , P=0.104). Conclusion:Pin1 in peripheral blood of RA patients is over-expressed. Th17 is increased and Treg is decreased. ATRA combined with other traditional drugs can reduce Pin1 activity, promote Treg growth and improve disease activity of RApatients to a certain extent.

RESUMEN
Objective To compare Th1/Th2 drift situation in patients with lymphoma with that in patients with solid tumors, and establish the effective immune function detectable criterion of lymphoma in biological treatment process. Methods The whole blood samples of 10 patients with lymphoma, 202 patients with solid tumors including 36 patients with upper digestive tract cancer, 64 colorectal cancer, 43 lung cancer and 20 the other malignancies, and 30 healthy persons as controls were collected. Stimulation agent was used to stimulate the cells in order to increase cell factor expression and fluorescent labeled specific anti-cytokine monoclonal antibody was used to bind with specific antigen. The expression of specific cytokines was detected by flow cytometry. Results Positive percentages of IFN- γ and IL-4 and ratio of IFN- γ /IL-4 in CD+4 T cells of human peripheral blood had statistically differences between in patients with lymphoma and controls (P < 0.05). The ratio of Thl/Th2 (CD+4 intracellular cytokine INF-α/IL-4) in patients with lymphoma was lower than that in patients with upper digestive tract cancers (esophagus and stomach cancers) (P = 0.023), however, had no statistical differences with that in patients with other solid tumors (colorectal, lung, kidney, breast and other tumors), but had a downward trend. Conclusion Immune functions in patients with lymphoma are lower than those in patients with solid tumors and immune treatment is a necessary to adjuvant chemotherapy. The ratio of Th1/Th2 (INF- α/IL-4) is expected to become effective detection criterion.

RESUMEN
Objective To investigate the relative activity of multidrug resistance P-glycoprotein in the plasma of breast cancer patients, analyze the expression of P-glycoprotein before and after chemotherapy and evaluate its clinical value. Methods The plasma of patients and chemical reagents were mixed and distributed into the 96-well plate. The plate was read at 340 nm absorbaace before and after reaction. The variation of absorbance for each well was calculated, and then relative activity of each sample was compared to the referent compound activity. The relative activity of over 30 % was taken as positive expression of the P-gp for each sample. Results The frequency of P-glycoprotein expression was significantly increased from 16.2 % before chemotherapy to 43.2 % after chemotherapy (P<0.05). The positive expression of P-glycoprotein before and after chemotherapy were 5/6 and 9/16, respectively, in patients with positive lymph node metastasis, and 1/6 and 7/16, respectively, in patients with negative lymph node metastasis. Conclusion The results of this preliminary study suggest in P-glycoprotein expression in plasma of patients play an important role in the selection of drugs, which may be useful to evaluate the prognosis for treatment of breast cancer patients.
RESUMEN
Objective To investigate the expression of NKG2D peripheral blood of patients with esophageal carcinoma and expression of the soluble form of major histocompatibility complex class Ⅰ-related chain A (MICA). To analyze and discuss the function of NKG2D in anti-esophageal carcinoma mechanism and its relation with escape of immunosurveillance of cancer. Methods Flow cytometry analysis was used to detect NKG2D in the peripheral blood of 50 patients with esophageal carcinoma and 25 normal control individuals. Enzyme-linked immunoabsorbent assay was used to measure serum levels of soluble MICA. Results The expression of NKG2D were(87.25±3.06), (88.38±4.24), (92.46±1.46) respectively. Compared with the normal control individual, the expression of NKG2D in esophageal carcinoma group was significantly low; Among patients categorized according to most disease parameters tested (tumor size, grade of differentiation, regional lymph node status, disease stage), soluble MICA levels in sera did not statistically differ from those in normal control individuals. Patients with stage Ⅳ disease and/or regional lymph node metastasis, exhibited significantly higher serum levels of soluble MICA than control individuals. Conclusion The activity of NK cell and the anti-cancer cellular immunity level reduce in patients with esophageal carcinoma. The decrease of the receptor NKG2D is a reason for the descend of the the activity of NK cells. The escape of immunosurveiilance with esophagal carcinoma may correlate with down-regulate of NKG2D expression and up-regulate of sMICA.
