Methods 54 patients who were diagnosed with primary IgA nephropathy in our hospital were collected.All patients were randomly divided into experimental group and control group, 27 cases in each group.Control group was given conventional Benazepri1 Hydrochloride Tablets 10 mg, 1 times per day orally;given Dipyridamole Tablets 50 mg, 3 times per day orally, patients in experimental group were given tripterygium glycosides 20 mg on the basis of control group treatment orally,3 times per day.All the patients were treated for 6 month.After the treatment, the serum levels of Ca,P,β2-GPI/ox-LDL and renal function related index were detected in all patients.Results Compared with control group post-treatment, the serum level of Ca was higher(P<0.05); and the serum level of P was lower in experimental group(P<0.05); the serum level of β2-GPI/ox-LDL was lower in experimental group(P<0.05);the serum levels of Scr and BUN were lower in experimental group(P<0.05).Conclusion The tripterygium glycosides can significantly reduce the serum levels of P,β2-GPI/ox-LDL,Scr and BUN,and increase serum Ca level in patients with IgA nephropathy, improve renal function.

Objective To investigate the relationship between the activity of nicotinamide adenosine dinucleotide phosphate(NADPH ) oxidase in peripheral blood mononuclear cell and left ventricular remodeling in patients with acute myocardial infarction (AMI).Methods Fifty-two patients with AMI hospitalized from December 2010 to June 2011 were selected as AMI group,and 25 patients with paroxysmal supraventricular tachycardia hospitalized in the same period were selected as control group.All patients were examined by Doppler echocardiography and left ventricular mass index (LVMI) was calculated.Fasting blood was drawn on the second day after hospitalization to measure the level of biochemical indexes,malondialdehyde(MDA ) and the activity of NADPH oxidase.The correlation of the level of MDA,the activity of NADPH oxidase and LVMI was analyzed.Results The level of MDA in AMI group was significantly higher than that in control group [(6.14 ±t 2.80) μ mol/L vs(2.95 ± 1.82) μmol/L,P ＜ 0.01 ].The levd of O2- in AMI group was also obviously higher than that in control group [(21.61 ± 10.66) RLU/mg protein vs.( 7.12 ± 4.48 ) RLU/mg protein,P ＜ 0.01 ],as well as the activity of NADPH oxidase [ ( 2.84 ± 1.05 ) RLU/mgprotein vs.( 1.97 ± 0.80) RLU/mg protein,P ＜ 0.01].Positive correlation was found between LVMI and the level of MDA(r =0.57,P ＜ 0.01 ),as well as between LVMI and the activity of NADPH oxidase(r =0.71,P＜0.01 ).Conclusions The activity of NADPH oxidase in peripheral blood mononuclear cell inereases in AMI patients and plays an important role in left ventricular remodeling after AMI.

Objective:This work aims to use the characteristics of dendritic cells (DCs) pulsed with recombinant human HSP70, which can present and process tumor antigens, to enhance the killing activity of cytotoxic t lymphocytes (CTLs) against breast neoplasms. Methods:Autologous DCs were isolated from peripheral blood mononuclear cells and then stimulated in vitro with granulocyte macrophage-colony stimulating factor and interleukin-4. The DCs were loaded with A549 tumor cell freeze-thaw lysate, and rhHSP70 was added as an immune adjuvant. The specific groups were subjected to tumor-specific cytotoxic assay, enzyme-linked immunosorbent assay, and fluores-cence-activated cell sorting. Results:DCs pulsed with A549 tumor cell lysate enhanced the growth expansion of CTLs, upregulated CD40 and CD80 populations in CTLs, and augmented Th1 cytokines. In addition, the cytotoxicity of specific CTLs against A549 was highly enhanced. The above indications became more obvious after the addition of rhHSP70. Conclusion:DCs pulsed with freeze-thaw cell lysates derived from breast cancer can enhance growth expansion of lymphocytes. They may serve as an effective tumor antigen to stimulate the proliferation of specific CTLs, which are very effective in activating specific T-cell responses against breast cancer cells in vitro. The improved anti-tumor immunity response by DC-based vaccines may be related to the maturation of the DCs promoted by rhHSP70.

ObjectiveTo investigate the impact of blood glucose,blood pressure and blood uric acid level on hematuria in patients with acute coronary syndrome (ACS).MethodsOne hundred and sixty-two ACS patients were selected and received standardized treatment after admission to hospital.Urine test was taken and patients were divided into no hematuria group(37 cases),microscopic hematuria group (56 cases) and gross hematuria group(69 cases) according to the results.Blood pressure,fasting and postprandial 2 hours blood glucose,glycated hemoglobin and blood uric acid level were measured and compared among three groups.ResultsMicroscopic hematuria group compared with no hematuria group,fasting and postprandial 2 hours blood glucose,glycated hemoglobin,systolic blood pressure and blood uric acid level raised 58.0％[(7.9 ±0.7) mmol/L vs. (5.0 ± 1.1) mmol/L],33.3％[(12.4 ±0.8) mmol/L vs.(9.3 ± 0.6 ) mmol/L ],48.2％ [ ( 8.3 ± 0.8 )％ vs.( 5.6 ± 0.5 )％ ],23.8％ [ ( 151.6 ± 7.0) mm Hg ( 1 mm Hg =0.133 kPa) vs.(122.5 ±9.9) mm Hg],29.2％ [(635.4 ±47.4) μmol/L vs.(491.8 ±83.4)μmol/L]respectively,there were significant differences (P ＜ 0.05 or ＜ 0.01 ).Gross hematuria group compared with microscopic hematuria group,the above mentioned indexes raised 16.5％[ (9.2 ± 1.1 ) mmol/L vs.(7.9 ± 0.7)mmol/L],30.6％[ ( 16.2 ± 1.8) mmol/L vs.( 12.4 ± 0.8) mmol/L],14.5％[ (9.5 ± 0.8)％ vs.(8.3 ± 0.8)％ ],18.8％[(180.1 ± 12.3) mm Hg vs.(151.6 ±7.0) mm Hg],34.6％[(855.5 ±74.5) μ mol/L vs.(635.4 ±47.4 ) μ mol/L ] respectively,there were significant differences ( P ＜ 0.05 or ＜ 0.01 ).Gross hematuria group compared with no hematuria group,the above mentioned indexes increased significantly(P＜ 0.01 ).The level of diastolic blood pressureamong three groups had no significant difference(P ＞ 0.05).The Logistic regression analysis showed that fasting and postprandial 2 hours blood glucose (r =3.175,P =0.001 ;r =0.906,P =0.001 ),glycated hemoglobin ( r =16.109,P =0.001 ),systolic blood pressure (r =0.429,P =0.003 ),blood uric acid level(r =1.317,P =0.004) were risk factors on hematuria after antiplatelet and anticoagulant therapy in ACS patients,the impact of glycated hemoglobin and fasting blood glucose on hematuria was stronger than that of blood uric acid level and systolic blood pressure.ConclusionWith the increase of blood glucose,systolic blood pressure,blood uric acid,the risk of hematuria increases in ACS patients.

Background and Purpose:dPET/CT is very expensive,so although the accuracy of hPET/CT is less than dPET/CT,it is better than CT,and is useful for guiding the tumor staging before operation.This paper is evaluate the role of ~(18)F-fluorodeoxyglucose(FDG) hPET/CT in primary carcinoma of gastric cardia detection.Methods:26 patients with histologically proven primary carcinoma of gastric cardia underwent whole body hPET/CT imaging.Visual and semiquantitative analysis and standardized uptake value(SUV) were used to analyze the images.The results of hPET/CT study were compared with those of CT.Results:1.The sensitivity of hPET/CT in primary carcinoma of gastric cardia detection was 92.3%(24/26);two cases of signet ring cell carcinoma gave false negative results,and the primary lesions were small(

Purpose:To explore the problems in the treatment of elderly patients suffering from lung cancer. Methods:58 cases of elderly patients aged over 70 who received operation for lung cancer during Oct. 1997 to Aug. 2002 were analyzed retrospectively.Results:56 cases underwent resections (resection rate 96.6%), of which 48 cases (82.8%) had radical resection and 8 cases (13.8%) palliative resection.2 cases (3.4%) had exploratory surgery. Postoperative complications were found in 50 cases (86.2%), of which 2 cases died during perioperation period(mortality rate 3.4%). Conclusions:Old age is not the major determining factor when considering surgical operation as the treatment for lung cancer patients. In order to enhance resection rates especially radical resection rate and survival rate, to diminish postoperative complications and mortality, and thus to improve the quality of life for the elderly lung cancer patients, a series of measures must be taken. First, diagnosis and treatment of the associated condition must be emphasized. Second, full preoperative preparations with appropriate choice of the time and procedure for operation. Finally, intensive monitoring during the preoperative period and prevention and treatment of postoperative complications are also important factors to be considered.

Objective To design and synthesize compounds with protein tyrosine kinase(PTK)inhibitory activity with L029 as the lead compound. Methods L029 derivatives were designed and synthesized from L029 by reduction and/or substitution with the 3-dimethylamino-1-propyl,methyl acetate,methyl propionate in its active H and other sites. PTK activity was measured by enzyme-linked immunosorbent assay(ELISA). The inhibitory rate was calculated to screen out the compounds with PTK inhibitory activity. Re-sults Five target compounds were synthesized and their structures were confirmed by 1H NMR and MS. Three compounds T2,T3 and T5 were screened out with strong PTK inhibitory activity. Conclusion The synthetic routes of the target compounds are simple with mild reaction condition,and 3 compounds show strong inhibitory activity by ELISA. These results can provide reference for the further design and synthesis of this kind of molecules.

Objective: To investigate the incidence and risk factors of catheter-related venous thrombosis (PICC-DVT) after peripherally inserted central catheter (PICC) in patients with hematologic malignancies, and to analyze the safety of anti-coagulation therapy with low-molecular-weight heparin. Methods: From August 2016 to June 2018, 43 patients with hematologic malignancies received PICC in Baoan District People's Hospital of Shenzhen City were enrolled. The patients were divided into low-molecular-weight heparin anticoagulation group (22 cases) and blank control group (21 cases) according to the random number table method. The blood routine, coagulation quadruple, D-dimer, protein C activity, protein S activity, and antithrombin Ⅲ activity before and after catheterization were compared between the two groups. Results: Of the 43 patients, 5 cases (11.62%) occurred PICC-DVT within 1 month after PICC, including 2 cases (9.09%) in the low-molecular-weight heparin anticoagulation group, and 3 cases (14.29%) in the blank control group, the difference between the two groups was not statistically significant (P = 0.664). No pulmonary embolism occurred in all patients with PICC-DVT. One case in the blank control group developed PICC-DVT and catheter-associated staphylococcus aureus infection, the patient was extubated after anti-infection and thrombolytic therapy, the other patients with PICC-DVT were not extubated, and the thrombus was dissolved after anticoagulant therapy. There were no significant differences in the white blood cell count, platelet count, prothrombin time, activated partial thromboplastin time, D-dimer, protein C activity, protein S activity, and antithrombin Ⅲ activity between the low-molecular-weight heparin anticoagulation group and blank control group (all P > 0.05). The anticoagulant index (protein C, protein S or antithrombin Ⅲ activity) was decreased in 5 patients with PICC-DVT, and in 38 non-thrombotic patients, the anticoagulant index was reduced in 16 patients (42.11%), the difference was statistically significant (P = 0.021). Conclusions The incidence of protein C, protein S or antithrombin Ⅲ activity reduction in hematological malignancies patients with PICC-DVT is higher than that in non-thrombotic patients. Low-molecular-weight heparin anticoagulant therapy can not reduce the occurrence of PICC-DVT within 1 month after PICC in patients with hematological malignancies, but the treatment is safe and has no relevant bleeding event.
