1.Advances of PD-1/PD-L1 inhibitors in the treatment of esophageal squamous cell carcinoma
Journal of International Oncology 2021;48(2):113-116
Esophageal squamous cell carcinoma (ESCC) accounts for more than 90% of the confirmed cases of esophageal cancer in Asia, and the degree of malignancy is high. There is a growing number of research on ESCC immunotherapy, particularly programmed death-1 (PD-1) and programmed death-ligand 1 (PD-L1). Among them, the most studied PD-1/PD-L1 inhibitors in ESCC are nivolumab, pembrolizumab, camrelizumab, toripalimab, tislelizumab, atozolizumab, SHR-1316 and durvalumab. Some of the clinical trials of these drugs are still in progress, and some have initially shown good results.

OBJECTIVE:To observe clinical efficacy and ADR of domestic recombinant human interleukin-11(Ⅰ)(rhIL-11 (Ⅰ))in the treatment of thrombocytopenia in patients with malignant tumor. METHODS:In self-controlled trial,50 malignant tumor patients with thrombocytopenia induced by radiotherapy and chemotherapy were injected with 25 ?g?kg-1?d-1 rhIL-11(Ⅰ) subcutaneously. Drug withdrawal was conducted after consecutive 10 days injection or platelet count being higher than 300?109?L-1. RESULTS:The minimum mean value of platelet were(56.53?27.11)?109?L-1 after radiotherapy and chemotherapy and(126.73? 57.58)?109?L-1 after rhIL-11(Ⅰ)treatment(P

Objective To explore the blood sugar controlling for elderly patients with fracture and diabetes mellitus. Methods Twenty patients with fracture complicated with diabetes were managed with mental education and diet controlling. Meanwhile nursing measures were done to prevent infections, bedsores and deep vein thrombosis (DVT). Results The fasting blood sugar levels of the 20 elderly patients were well controlled below 7.8 mmol / L. There were no related complications. Conclusion Such nursing measures as psychological counseling and diet control are helpful for a steady maintenance of blood sugar for feasibility of surgical operation, to ensure successful manipulation of the surgical operation. Prevention of infection, bedsore and DVT is critical for ensuring the success of operations.

Objective To study the dynamic changes of regional cerebral blood flow(rCBF) in hematoma, perihematoma and their enantiomorph in the contralateral hemisphere in the patients with acute intracerebral hemorrhage(ICH). Methods 15 patients of acute basal ganglia hemorrhage were divided into different groups according to the Chinese Stroke Scales, 10 patients were minor, the other 5 patients were moderate. 99mtechnetium-ethyl -cysteinate-dimer single-photon emission CT ( 99mTc-ECD SPECT) were performed within 3 days after onset of the disease and re-examined at 16 days. The method of region of interesting (ROI) was used to measure the uptake counts in the core of hematoma, frontal or parietal region around the lesion, the center of cerebellum and their enantiomorphs in the contralateral hemisphere, respectively,and to calculate the ratio of uptake counts.Results The uptake counts showed difference in the second time exam between perilesion and its enantiomorph in minor patients ( P0.05). The uptake counts of contralateral cerebellum were less than those of hemorrhage lateral cerebellum ( P

Eleven elderly patients undergoing maintenance hemodialysis without ARB or ACEI within 4 weeks were enrolled. Anti-hypertensive agents were replaced by telmisartan gradually to maintain stable blood pressure. Before and after 6 or 12 weeks of treatment, blood biochemical profiles, fasting blood glucose, fasting plasma insulin, insulin resistance index(HOMA-IR), blood pressure, and body weight were recorded. Our results showed that telmisartan did not affect body weight, high-density lipoprotein (HDL), triglyceride (TG), SCr, BUN, Alb, K+ , and PTH, although led to a significant decrease in TC and low-density lipoprotein (LDL). Following telmisartan treatment, FPG did not change significantly, but fasting insulin decreased from 13.9±3.6 mU/ml to 9.9±2.7 or 9.1±2.3 mU/ml at 6 and 12 week (P<0.01), and HOMA-IR decreased from 3.5±1.4 to 2.4±0.8 or 2.2±0.8 at 6 and 12 week (P<0.05). These results suggest that insulin resistance in elderly patients with MHD may be improved by telmisartan.

Objective To investigate the effect of lectin like oxidized low density lipoprotein receptor 1 ( LOX-1 ) in NRK52E intaking lipid induced by oxidized low density lipoprotein ( ox-LDL). Methods NRK-52E was incubated with ox-LDL (0,25,50, and 100 g/ml ) for 24 hours or pre-treated with the chemical blocker of LOX-1 receptor- polyI or carrageenan, and then exposed to 50 μg/ml of ox-LDL. LOX-Ⅰ mRNA was examined by real-time PGR. LOX-1 protein was assessed by Western blot analysis. Lipid deposit was examined by oil red O. Results LOX-1 mRNA expression in 25,50,100 μg/ml ox-LDL group was 2. 13, 10. 14, 20. 81 times of that in 0 g/ml ox-LDL group ( P <0. 05 ,respectively). LOX-1 protein expression in 25,50,100 μg/ml ox-LDL group was 2. 53,12. 18,21.45 times of that in 0 μg/ml ox-LDL group( P <0. 05 ,respectively). Following the increased LOX-1, lipid intake increased. Pre-treatment with Poly Ⅰ or carrageenan, LOX-1 mRNA expression deceased by 48% or 47%, LOX-1 protein deceased by 72% or 65%, lipid intake induced by 41% or 49% ( P <0.05 ,respectively). Lipid had a close relationship with LOX-1 ( r = 0. 87, P < 0. 05). Conclusion Ox-LDL induced NRK52E to express LOX-1 and promoted NRK52E to intake lipid, and this effect could be partly blocked by LOX-1 blocker.

The mRNA and protein expression of thymidylate synthase (TS), thymidine phosphorylase (TP) and dihydropyrimidine dehydrogenase (DPD) and their relationship with prognosis were investigated. Real-time quantitative RT-PCR (Taqman) was used to detect the mRNA expression of TS, TP and DPD in formalin-fixed and paraffin-embedded 106 samples of epithelial ovarian cancer and 29 normal ovaries. A TATA box-binding protein (TBP) was used as an endogenous reference gene. A relationship between TS, TP, DPD expression and clinicopathologic features was investigated. The protein location and expression of TS, TP and DPD was examined in the same patients by an avidin-biotin-peroxidase immunohistochemistry. TS and TP mRNA expression levels were significantly higher in tumor group than in normal controls, with the average value of TS and TP mRNA being 6.14+/-0.62 and 0.59+/-0.06 in tumor tissue, and 0.71+/-0.14 and 0.16+/-0.04 in normal tissue, respectively. DPD mRNA expression levels were significantly lower in tumor group (0.11+/-0.02) than in normal controls (0.38+/-0.05). There was statistically significant difference in TS and TP mRNA expression levels among different pathological grades and clinical stages (P<0.05), but histological subtype was not significantly associated with TS and TP mRNA expression. DPD gene expression was not significantly associated with any clinicopathological parameters. Immunohistochemistry revealed that TP protein was mainly distributed in nucleus, and TS and DPD mainly in cytoplasm. The protein expression intensity of TS, TP and DPD was coincided with the mRNA expression levels. It was concluded that TS, TP mRNA and protein expression levels were significantly higher in epithelial ovarian cancer, and DPD mRNA and protein expression levels were significantly lower. The expression levels of TS and DPD were related to the patients' prognosis and survival. Combined gene expression levels of TS, TP and DPD represent a new variable to predict the clinical outcome in ovarian cancer. The association of TS, TP and DPD expression levels with survival suggests an importance of these genes for tumor occurrence and progression.
