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

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 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.

Objective To explore the experience in nursing the patients with esophageal high-grade intraepithelial neoplasia lesions treated with endoscopic submucosal dissection. Method A retrospective analysis was carried out among the patients with esophageal high-grade intraepithelial neoplasia lesions to look into the nursing care to the patients. Results Thirty patients were successfully stripped, and no surgical complication occurred. After intensive care, they were cured and discharged. Conclusion Professional and meticulous care can effectively improve the success rate of endoscopic submucosal dissection and reduce the incidence of complications, and promote the rehabilitation of patients.

AIM: To study the regulatory effect of curcumin on expression of heme oxygenase-1 (HO-1) in the lung of rat treated with LPS. METHODS: Eighteen rats were divided into three groups injected with different agents via lingua vein: control group (animals received equivalent saline) , LPS group (animals received a bolus dose of LPS 5 mg?0.5 mL-1?kg-1) and LPS+ curcumin group (animals received AP- 1 inhibitor curcumin 20 mg?0.5 mL-1?kg-120 min before the injection of LPS 5 mg ?0.5 mL-1?kg-1) . The expression of HO-1 mRNA and protein in the lung were examined 7 h after LPS administration by reverse transcribed polymerase chain reaction (RT- PCR) and Western blotting, respectively. Carboxyhemoglobin (HbCO) formation within pulmonary tissue was measured to represent CO content. RESULTS: The results showed that HO- 1 mRNA and protein expression as well as CO content in the lung of rats in LPS group were significantly higher than those in control group (P

AIM To examine the effects of lovastatin, probucol on the intracellular cholesterol content and cholesterol efflux. METHODS With the model of foam cells through depositing the oxidized low-density lipoprotein (OXLDL) into mouse peritoneal macrophages, intracellular cholesterol content was examined by high performance liquid chromatography after the administration of lovastatin and probucol at different concentration. RESULTS The CE/TC ratios of the model group were beyond 50% and extremely higher than those of the normal and negative groups, suggesting that the model of foam cells was established triumphantly. Lovastatin decreased intracellular TC, CE and CE/TC significantly and dose-dependently. Probucol also possessed such effects on intracellular TC, CE, but no dose-dependently, and no effect on the ratio of CE/TC. CONCLUSION The results showed lovastatin might be conducive to plagues stability by increasing cholesterol efflux from the foam cells and decreasing the intracellular cholesterol content. Probucol did not have this effect although it decreased intracellular TC and CE content.

AIM: To investigate the relationship between change of inducible nitric oxide synthase (iNOS) and rat renal damage in dietary hypercholesterolemia. METHODS: High cholesterol (HC) group was fed with diet supplemented with 4% cholesterol and 1% cholic acid for 8 weeks. Another group was fed with normal diet. Expression of iNOS at protein level was evaluated by immunohistochemical staining and iNOS mRNA levels in renal cortex by reverse transcription-polymerase chain reaction (RT-PCR). The apoptotic cells in renal tissue at 8th week were evaluated by TUNEL method. RESULTS: Total serum cholesterol and LDL-cholesterol levels in HC group were higher than that in control group ( P
