OBJECTIVE: To observe the clinical therapeutic effects of Dishen Qufeng Decoction (DSQFD), a compound traditional Chinese herbal medicine, in treatment of allergic rhinitis. METHODS: Sixty cases of allergic rhinitis were selected and randomized into DSQFD group (30 cases) and cetirizine group (30 cases), and the patients were orally administered DSQFD and cetirizine respectively. The integrals of patients' symptoms, such as sneezing, nose running, nasal occlusion and nasal itching, signs in the nasal conchae and peripheral blood eosinophil (EOS) count were abserved count before and after treatment. RESULTS: DSQFD obviously improved the symptoms and signs of allergic rhinitis. The total response rate of DSQFD treatment was 83.3%, while that of the cetirizine treatment was 86.7%; the EOS counts in both groups were significantly decreased. These results showed statistical difference between the two groups. CONCLUSION: DSQFD is an effective preparation of traditional Chinese medicine for treating allergic rhinitis.

Objective To investigate the effect of elemene on mRNA expressions of tumor necrosis factor (TNF) receptor associated factor 6 (TRAF6) and caspase-8 in tumor tissues of mice bearing hepatoma H22.Methods Forty BALB/c mice models bearing hepatoma H22 were established by subcutaneous inoculating tumor cells.Forty BALB/c mice were randomly divided into 4 groups:model group,low-and high-elemene dosage groups,and cisplatin group.The tumors after executing mice were weighted.The mRNA expressions of TRAF6 and caspase-8 in tumor tissues were detected by quantitative real-time reversetranscription polymerase chain reaction (RT-PCR).Results The dosage of elemene could inhibit tumor growth.The inhibition ratio of cancer in the low-and high-elemene dosage and cisplatin group was 24.2％,27.4％,and 28.2％,respectively.It reduced significantly tumor weights(P ＜0.01).Compared to the model group,the expression level of TRAF6 mRNA on tumors was decreased significantly,while the expression level of caspase-8 mRNA was increased significantly in the other groups(P ＜ 0.05).Conclusions The present results indicated that molecular mechanism of inhibition of liver cancer growth treated by elemene might be through down-regulating mRNA expressions of TRAF6 and caspase-8,promoting tumor cells apoptosis,and achieving the anti-tumor effect.

Objective:To evaluate the value of neutrophil to lymphocyte and platelet ratio (N/LPR) for predicting 28-day mortality in sepsis patients.Methods:A retrospective analysis was conducted. The clinical data of 154 sepsis patients admitted to intensive care unit (ICU) of the Affiliated Hospital of Jiangsu University from June 2017 to June 2020 were enrolled. The time of first diagnosis of sepsis in ICU was taken as the research starting point, and the death or 28 days as the end point. The 28-day outcomes of patients were recorded. The counts of peripheral blood neutrophil (NEU), lymphocyte (LYM) and platelet (PLT) were collected from all the enrolled patients within 3 days after diagnosis of sepsis. The ratios of N/LPR and NEU/LYM (NLR) were calculated respectively. The differences of N/LPR and NLR between survival group and death group were compared. Receiver operating characteristic (ROC) curve analysis was used to analyze the value of N/LPR and NLR on predicting the 28-day mortality of sepsis patients. According to the best cut-off value of ROC curve analysis, the 28-day mortality of patients with sepsis was analyzed by subgroup analysis, and the 28-day cumulative survival of patients with sepsis was analyzed by Kaplan-Meier survival curve.Results:Of the 154 sepsis patients, the patients with age < 18 years, pregnancy, blood disease, taking aspirin or other antiplatelet drugs within 1 week, taking leucocyte drugs within 1 week, length of ICU stay < 3 days and incomplete data were excluded. Finally, 50 patients were enrolled. Among them, 30 patients survived on the 28th day and 20 died. Compared with the survival group, the levels of N/LPR and NLR in the death group were significantly increased (N/LPR: 23.85±11.99 vs. 12.41±5.25, NLR: 17.83±8.69 vs. 10.75±3.63), with statistical differences (both P < 0.01). ROC curve analysis indicated that the area under ROC curve (AUC) of N/LPR for predicting 28-day death of sepsis patients was 0.827, it was higher than that of NLR (AUC = 0.762). Base on N/LPR≥15.48 as a predictor of cut-off value of death in 28 days of sepsis patients, the sensitivity was 75.0% and the specificity was 80.0%, respectively. Base on NLR≥10.65 as a predictor of cut-off value of death in 28 days of sepsis patients, the sensitivity was 75.0% and specificity was 56.7%, respectively. Subgroup analysis showed that the 28-day mortality in the patients with N/LPR≥15.48 ( n = 21) was significantly higher than those with N/LPR < 15.48 ( n = 29; 71.4% vs. 17.2%, χ 2 = 14.901, P < 0.01); and the 28-day mortality in the patients with NLR≥10.65 ( n = 28) was also significantly higher than those with NLR < 10.65 ( n = 22; 53.6% vs. 22.7%, χ 2 = 4.884, P < 0.05). The results were consistent with Kaplan-Meier survival curve analysis. Conclusion:Peripheral blood N/LPR has a good predictive value for 28-day mortality of sepsis patients, and which is better than NLR.

OBJECTIVE To study the correlation of novel organic cation transporter 2 （OCTN2） with the chemosensitivity of prostate cancer cells to oxaliplatin. METHODS Tumor samples of patients receiving radical prostatectomy were collected， and OCTN2 protein was detected with immunohistochemistry； the primary cells of the specimen were cultivated to obtain prostate cancer cell line. Inductively coupled plasma mass spectrometry was used to detect the uptake of low concentration （0.1 μmol/L） of oxaliplatin by cancer cells. Real-time PCR and Western blot were used to detect the mRNA and protein expressions of OCTN2 in cancer cells； the prostate cancer cells with the highest and lowest expression of OCTN2 protein were selected， and IC50 of oxaliplatin to prostate cancer cells was analyzed by ATP-TCA method. The inhibitory rate of plasma peak concentration of oxaliplatin （50 μmol/L） to prostate cancer cells was detected by MTT assay. Spearman method was used to analyze the relationship of the uptake of oxaliplatin by prostate cancer cells with inhibitory rate of oxaliplatin to prostate cancer cells and 505916443@qq.com mRNA expressions of OCTN2. RESULTS OCTN2 was located on the membrane of cancer cells， and the uptake of zjdtztougao@163.com oxaliplatin by cancer cells was 0.283±0.264 （n＝12）mRNA and protein expression of OCTN2 varied significantly among different cancer cells. The sensitivity of cancer cells with high expression of OCTN2 to oxaliplatin （IC50 of 4.61 μmol/L） was higher than that of cancer cells with lower expression of OCTN2 （IC50 of 26.23 μmol/L）. The inhibitory rate of oxaliplatin to cancer cells was （25.4±10.8）% （n＝12）. There was a correlation between the uptake of oxaliplatin by prostate cancer cells and the inhibition rate of oxaliplatin to prostate cancer cells and mRNA expression of OCTN2 （P＜0.05）. CONCLUSIONS High-expressed OCTN2 may promote the uptake of oxaliplatin by prostate cancer cells， and its expression can serve as a reference for predicting the sensitivity of prostate cancer cells to oxaliplatin chemotherapy.
