ObjectiveTo explore the effect of Shuanglong pill which can vivid blood and relax thread pulse on cardial morphology and haemodynamics in experimental myocardial infarction (MI) rats.Methods66 rats ligated left coronary artery were randomly divided into large dose group of Shuanglong pill (LDG), small dose group of Shuanglong pill (SDG), the normal control (NC) and the control group of MI. Half in each group received 2 week treatment and the other received 4 week treatment, and were spiled in femoral and common carotid artery respectively. Parameters of cardiac haemodynamics were monitored by eight lead physiological recorder. ResultsLeft ventricular systolic maximum velocity in LDG, SDG and DC was more significantly elevated than in MI, after 2 weeks and 4 weeks of treatment, but it was lower than NC. There were no significant differences among LDG, SDG and DC. Ventricular systolic maximum velocity in LDG was more significantly elevated than in MI after 2 week treatment.ConclusionTreating MI with Shuanglong pill can improve left ventricular systolic maximum velocity, and diastolic phase function of left ventricular also elevate during the acute stage of MI by using large dose.

Wistar rats were intragastrically administered with different doses (2, 5 and 10 g / kg body weight) of haematitum. 1H NMR-based metabonomic analysis coupled with multivariate statistical analysis (principal component analysis and partial least squares-discriminant analysis) was used to analyze the metabolic profiles of the urine samples collected from the treated rats. Univariate analysis on the 1H NMR spectra of urine (1 d before administration, 1-5 d post administration) was used to screen out the potential features of haematitum. Significant treatment related changes were observed for the levels of citrate, tuarine, creatinine,α-ketoglutarate, succinate and dimethylglycine, which could be used as potential features of haematitum. A trend of recovery in connection with dose levels was observed overtime. Such biochemical changes indicated that haematitum treatment at the dose of 2, 5 and 10 g / kg body weight affected the Krebs cycle and glucose metabolism, energy metabolism, choline metabolism and dimethylglycine metabolism in rats. These changes may attribute to the disturbances of hepatic function in 10 g / kg body weight group.

OBJECTIVE To study the effect of Qing Yi Tang on acute pancreatitis(AP),especially AP complicated with endotoxemia and its possible mechanism.METHODS Fourty Wistar rats were divided into 5 groups including group A(the control group),group B(the AP group),group C(the AP group treated with Qing Yi Tang),group D(the AP group treated with LPS) and group E(the AP group treated with LPS + Qing Yi Tang).Pathological damage of pancreatic tissue was scored with HE staining.The mRNA expression of TNF-? was measured with semi-quantitative RT-PCR,and activation of NF-?B was detected with flow cytometry(FCM) assay.RESULTS It was shown in results that the expression of TNF-? mRNA,activation of NF-?B and pathological damage of the group B were all obviously higher than those of the group A.After treated with LPS which might promote the activation of NF-?B,there was seen the further rise of the activation of NF-?B,expression of TNF-? mRNA and pathological damage.When Qing Yi Tang intervention was applied,the activation of NF-?B and the expression of TNF-? mRNA could be remarkably relieved,so did the pathological damage of pancreas.CONCLUSIONS Qing Yi Tang may be applied to decrease activation of NF-?B and the expression of TNF-? so as to treat AP or AP with endotoxemia.

0.05).Conclusions ATP-TCA could be used to individualize chemotherapy by selecting agents for particular patients of cervical cancer.The expression of GST-? and TS protein might be useful biomarkers to predict the resistance to DDP and 5-FU in patients with cervical cancer.

Objective To define the maximum-tolerated dnse(MTD)and observe the side effect of escalating cisplatin with 5-fluorouracil in concurrent chemoradiotherapy for esophageal carcinoma in Chinese,with toxicity studied.Methods Previously untreated fifteen Chinese patients suffering from esophageal carcinoma received conventional fractionafiun radiotherapy,with 5 daily fractions of 2.0 Gy per week.The total radiation dose was 60 Gy.Concurrent chemotherapy dose escalation was given by the relatively safe and kidney-sparing modified Fibonacci sequence.The starting dose was cisplatin 37.5 mg/m~2 D1 and 5-fluorouracil 500 mg/m~2 D1-5, respectively.This regimen was repeated 4 times every 28 days.Escalation dose was eisplatin 7.5mg/m~2 and 5- fluorouracil 100mg/m~2.Every cohort contained at least 3 patients.If no dose-limiting toxicity(DLT)was observed, the next dose level was opened for entry.These courses were repeated until DLT appeared.MTD was declared as one dose level below which DLT appeared.Results DLT was defined as grade 3 radiation-induced esophngitis at the level of cisplatin 60 mg/m~2,5-fluorouracil 700 mg/m~2.MTD was defined as eisplafin 52.5 mg,/m~,5- fluorouracil 700 mg/m~2.The major side effect were radiation-induced esophagitis,leucopenia,nausea,vomiting and anorexia.Conclusion Maximun tolerated dose of cisplatin with 5-fluorouracil in concurrent chemoradiotherapy in the Chinese people with esophageal carcinoma were eisplatin 52.5 mg/m~2 D1,5-fluorouracil 700 mg/m~2 D1-5,repeated 4 times every 28 days.

Objective To evaluate clinical significance of direct antiglobulin testing(DAT)in anemia in patients with severe chronic hepatitis B(CHB).Methods Red blood cell(RBC)-related parameters detection and DAT were performed among 30 healthy persons,30 CHB patients,and 50 severe CHB patients,clinical factors related to posi-tive DAT were analyzed.Results RBC count,hemoglobin (Hb)concentration,and hematocrit(HCT)level in severe CHB patients were all lower than CHB patients and healthy group(P <0.05),RBC distribution width(RDW)in severe CHB patients were all higher than CHB patients and healthy group(P<0.05);the positive rate of DAT in patients with se-vere CHB,CHB,and healthy group were 62.82%,13.33% and 0 respectively.RBC count,Hb concentration,and HCT level in severe CHB patients with positive DAT were all lower than severe CHB patients with negative DAT (all P <0.05),while RDW was higher than the latter (P=0.001);after RBC was separated through capillary,positive intensity of DAT of aged RBCs was higher than young RBCs in severe CHB patients (P <0.001);among severe CHB patients, DAT-positive and-negative patients differed in gender,age,alanine aminotransferase,total bilirubin,complement C3, C-reactive protein,and complication of diabetes(all P≤0.05).Conclusion Anemia in severe CHB patients may be re-lated to immune hemolysis of aged RBCs induced by antibody adsorption.

INTRODUCTION: Associations of variations in PLA2R1 and HLA-DQA1 genes with susceptibility to idiopathic membranous nephropathy (IMN) have been well documented. Association with spontaneous remission, however, is poorly defined in the Chinese Han population. METHODS: A Chinese cohort of 117 IMN patients and 138 healthy controls were recruited between July 2009 and November 2019. Case-control studies for single-nucleotide polymorphisms (SNPs) within HLA-DQA1 (rs2187668) and PLA2R1 (rs35771982, rs4664308, rs3749117, rs3749119) genes were performed. The contributions of these polymorphisms to predict susceptibility, titre of autoantibodies against the M-type phospholipase A2 receptor (anti-PLA2R1), glomerular PLA2R1 expression, and spontaneous remission were analysed. RESULTS: We found that variations in PLA2R1 (SNPs rs35771982, rs4664308, rs3749117) were strongly associated with IMN susceptibility, while SNP (rs2187668) within HLA-DQA1 did not increase the risk of IMN. All SNPs in PLA2R1 and HLA-DQA1 were not statistically associated with anti-PLA2R1 titre, glomerular PLA2R1 expression and spontaneous remission after Bonferroni correction ( CONCLUSION This study confirms that variations in PLA2R1 (SNPs rs35771982, rs4664308, rs3749117) are risk factors for IMN. We found excellent association of serum albumin level, anti-PLA2R1 titre and glomerular PLA2R1 positivity with non-spontaneous remission in IMN.

Objective:To prepare,purify the recombinant proteins of HSP70-like protein 1 (HSPTOL1) with a large fragment of chicken ovalbumin (OVA),and to investigate the bio-function of the fusion protein,providing a basis for fur- ther study of the effect and the mechanism of HSPTOL1 as an adjuvant.Methods:The vector containing HSP70L1 cDNA and large fragment of OVA was constructed.The expression of OVA-HSP70L1 fusion protein was induced and the products were purified from inclusion bodies by His-Trap metal chelation chromatography and DEAE ion-exchange chromatography. The bio-activity of the fusion protein was examined by detecting its ability to activate dendritic ceils and to promote the se- cretion of cytokines.Results:The vector was successfully constructed and the molecular weight of the fused OVA- HSPTOL1 protein (with a purity of over 95%) was 68 000.The fusion protein effectively promoted the maturation of den- dritic cells and the production of cytokines such as interleukin-12 and tumor necrosis factor-?.Conclusion:HSPTOL1 may be an effective adjuvant in the fusion protein and it may also promote antigen specific Thl type i mmol/Luno-respon- ses.

The aim of study was to investigate the killing effect of double suicide gene system mediated by retroviral vector on K562 cells in vivo and ex vivo. CDglyTK gene was transfected into PA317 cells by using lipofectamine. K562 cells were infected with viral supernatant. K562/CDglyTK cells were treated with 5-fluorocytosine (5-FC) and/or ganciclovir (GCV). Mice were randomly divided into three groups: tumor formation, tumor inhibition and tumor therapy. Each mouse was implanted with K562/CDglyTK cells or K562 cells. The results indicated that the killing effect of 5-FC in combination with GCV on K562/CDglyTK was more significant than using 5-FC or GCV alone. In vivo study showed that after being injected subcutaneously with K562 cells and K562/CDglyTK cells, there was not obvious difference in tumor formation rate of mice, 5-FC + GCV could suppress tumor formation of the K562/CDglyTK cells. After being treated with 5-FC and GCV, the median tumor volume of mice implanted with K562/CDglyTK cells decreased obviously, compared with the control group. Their median survival was significantly prolonged. It is concluded that double suicide genes are more effective for killing effect on K562 cells in vivo and in ex vivo. It may be applicable to clinical gene therapy.

The full-length P32 gene and the truncated P32 gene (MP-32) were amplified from the recombinant plasmid pMD-P32 by polymerase chain reaction (PCR) and cloned into pcDNA3. 1(+) and pcDNA3.1-CpG respectively. The recombinant plasmids (pcDNA3.1-P32, pcDNA3.1-CpG-P32 and pcDNA3. 1-CpG-MP32) were transfected into BHK-21 cells by using lipofectin. The expressed P32 protein was confirmed by indirect immunofluorescence assay (IFA). The BALB/c mice were immunized with these recombinant plasmids by intramuscular injection. The specific antibodies aginst CPV were detected by ELISA kit weekly. The murine splenic T lymphocyte subgroups CD4+ and CD8+ were detected by flow cytometry. Results showed that the P32 protein was expressed successfully in vitro. After 2 weeks post im munization, the specific IgG antibodies against CPV were detected in the vaccinated mice. The percentage of CD4+ /CD8+ T cells was significantly higher than that of the control. In conclusion, these constructed eukaryotic vectors could induce humoral and celluar immune responses in mice.
