Objective To observe the clinical efficacy of therapy of soothing liver and clearing heat for the treatment of glucocorticoid-dependent adult chronic idiopathic thrombocytopenic purpura ( CITP) . Methods Thirty-two qualified glucocorticoid-dependent adult CITP patients with the syndrome of interior heat due to liver stagnation and liver failing in storing blood were enrolled into the study. Based on the primary regimen, the patients were additionally given Shugan Qingre Recipe ( mainly composed of Rhizoma Dioscoreae, Radix Bupleuri, Radix Paeoniae Alba, Radix Rehmanniae, Cortex Moutan, Herba Artemisiae Scopariae, Poria, Fructus Corni, Fructus Lycii, Herba Agrimoniae , Radix Rubiae, Radix Glycyrrhizae) for 3 months (12 weeks), 2 doses a day, decocting with water for oral use. Before and after treatment, the changes of Chinese medical syndrome scores and the laboratory indexes were investigated. Results (1) After treatment for 12 weeks, 10 cases were markedly effective, 16 effective , 5 improved, one ineffective, and the total effective rate arrived to 81.25%. ( 2) After treatment for one month, the scores of traditional Chinese medical syndrome were not improved ( P>0.05 compared with those before treatment) . At the end of 2-month and 3-month treatment course, the scores were improved obviously compared with those before treatment, the difference being significant (P<0.05 or P<0.01) . (3) Platelet count rose up from the fourth week of treatment, and the difference was significant compared with that before treatment ( P<0.01) . Conclusion Therapy of soothing liver and clearing heat shows certain ef fect for the treatment of glucocorticoid-dependent adult chronic CITP, and has satisfactory clinical prospect.

Objective The regulation of ornithine decarboxylase (ODC) gene expression and enzyme activity by corticosterone, the main glucocorticoid in rat, during rat liver regeneration induced by partial hepatectomy (PH) was evaluated.Methods Bilateral adrenaleetomies (ADX) and sham-ADX were performed on ether-anesthetized rats 3 days before PH.Corticosterone in sesame oil was injected subcutaneously to adrenalectomied rats. ODC mRNA, ODC protein and enzyme activity were detected by RT-PCR, Western blotting and high performance liquid chromatography (HPLC), respectively. Results The ODC mRNA levels, protein accumulation and enzyme activity were lower in the intact liver compared to the regenerating liver.After PH, mRNA levels were remarkably enhanced in all groups (n=6 in each group) and peaked at 5 hours post-PH. Till 7 hours, the contents in all groups from high to low were ADX group,control group (Sham-ADX group), ADX treated with 10mg/kg and 40mg/kg body weight corticosterone group, respectively. ODC protein accumulation in ADX rats was higher than that in control rats (n=13, the same below), but it decreasod in corticosterone-treated (10mg/kg) rats until 24 hours post-PH, with a strong decline seen in 40mg/kg corticosterone-treated rats. ODC activity was rapidly promoted, and the highest levels were observed at 6 hours after PH in all groups (n=6 in each group). After corticosterone treatment, the activities declined significantly at 6 hours post-PH, with the lowest value found in the 40mg/kg group. Conclusion Corticosterone treatment results in dose-dependent decreases in ODC mRNA and enzyme protein both in the intact liver and the regenerating liver. The change in ODC activity is partially related to alterations of ODC mRNA and protein accumulation.

Objective To investigate curative efficacy of tetramethylpyrazine in combination with chemotherapy in treatment of medium and advanced liver cancer and its effects on level of brain-derived neurotrophic factor ( BDNF).Methods 90 patients of medium and advanced liver cancer who received therapy from January 2011 to June 2012 were selected as research objects.According to therapeutic schemes, those patients were divided into the control group (n=42) and the observation group (n=48).The control group was treated with transcatheter hepatic arterial chemoembolization ( TACE) , while the observation group was treated with tetramethylpyrazine in combination with TACE.Then, the short-term curative efficacy, long-term curative efficacy, level of BDNF and adverse reactions were compared.Results The total short-term therapeutic efficacy ratio in the observation group was statistically higher than that in the control group ( 83.3% vs 64.3%, P <0.05 ).During the three-year follow-up, the one-year and two-year survival rate in the observation group was statistically same with that in the control group respectively (75.0% vs 66.7%, 66.7% vs 59.5%), while the three-year survival rate was statistically higher than that in the control group (52.1%vs 30.9%, P<0.05).After treatment, in comparison with the control group, level of BDNF in the observation group was statistically lower(P<0.05).During treatment, incidences of liver function deterioration, abdo minal pain and diarrhea, nausea and vomiting, fever and headache in two groups were statistically same.Conclusion Tetramethylpyrazine in combination with TACE is effective for medium and advanced liver cancer, which can increase short-term and survival rate to some extent, significantly reduce level of BDNF with not increasing incidence of adverse reactions.

Objective To study the etiological agent of hand, foot and mouth disease ( HFMD) and the genetic characteristics of coxsackievirus A16 ( CVA16 ) strains isolated from clinical specimens of patients with HFMD in Liaocheng city in 2013.Methods Throat swab and stool specimens were collected from patients with HFMD in the disease surveillance hospitals in Liaocheng city from January to December 2013.Samples pos-itive for CVA16 strains were screened out for the isolation of virus strains with rhabdomyosarcoma ( RD) cells and Vero cells.The entire VP1 coding regions of 9 randomly selected CVA16 isolates were amplified and se-quenced.BioEdit and MEGA4 softwares were used for homology analysis.A phylogenetic tree among the 9 CVA16 isolates and 56 CVA16 representative strains of known genotypes and subgenotypes was constructed.Re-sults The results of PCR analysis showed that 747(77.73%) out of 961 specimens were positive for HFMD and among them, 74 samples (9.91%) were positive for EV71 strains, 130(17.40%) were CVA16 strains and 543(72.69%) were other enterovirus strains.The 9 CVA16 strains clustered into the B2b evolution branch of B genotype with the representative strains, sharing 97.7%to 100%homologies in nucleotide sequences and 99.3%to 100%in amino acid sequences.Conclusion Although EV71 and CVA16 strains were identified, other enteric viruses were the predominant pathogens causing HFMD in Liaocheng city in 2013.The CVA16 iso-lates belonged to B2b subgenotype.The pathogen spectrum of HFMD had already changed.It is necessary to strengthen the surveillance for EV71, CVA16 and other enteric viruses and understand their genetic characteriza-tions, which would be of great significance for the prevention and control of HFMD.

Objective:To study the preventive and therapeutic effects of silk fibroin peptides (SFP) on acute alcoholism in mice. Methods:In first experiment, the mice were randomly divided into four groups, and every group was treated by 56o alcohol (ethanol dosage 7.56 ml/kg bw) via i.g. Eighty mice were fed normal saline (NS) and different dosages of SFP (0.1, 0.5, 2.5 g/kg bw) 30 min later respectively, then the rate of ebriety and time of sobriety were determined. Another 72 mice were also divided into four groups and given NS and SFP similarly. The concentration of ethanol in serum was measured 1 h, 2 h and 4 h later respectively. In second experiment, the mice were also divided into four similar groups, but 56o alcohol was given at 6.16 ml/kg?bw via i.g. NS and SFP were given similarly, 0.5 h before alcohol. Two experiments were performed to observe the effect of SFP on prevention of temulence. Results:The time of sobriety and concentration of ethanol of SFP groups fed 0.5 and 2.5g/kg bw were lower significantly than those of NS group (P

Objective: To study diagnostic and predictive value of levels of high sensitive C reactive protein (hsCRP) and cystatin C (CysC) for acute coronary syndrome (ACS) in aged patients.Methods: A total of 60 ACS patients (ACS group) treated in our hospital and 60 healthy subjects (healthy control group) undergoing physical examination during Dec 2013 to Sep 2015 were randomly selected.Serum levels of hsCRP and CysC, and abnormal rates of hsCRP and CysC were measured and compared between two groups.Results: Compared with healthy control group, there were significant rise in serum levels of hsCRP[(3.02±1.13) mg/L vs.(7.95±2.38) mg/L]and CysC[(0.75±0.11) μg/ml vs.(1.35±0.43) μg/ml], and abnormal rates of hsCRP (0 vs.13.33%) and CysC (0 vs.11.67%) in ACS group, P<0.01 all.Conclusion: Serum hsCRP and CysC level measurements can effectively predict and assess occurrence, development and prognosis of disease in ACS patients, and provide clinical valid evidence for its diagnosis, prevention and treatment.

Objective To observe the effects of secoisolariciresinol (SECO) and its metabolites, enterolactone (ENL) and enterodiol (END), on proliferation of MCF-7 cell line and to the probable mechanism. Method Effect of SECO, END, ENL and genistein (GEN) on MCF-7 proliferation was investigated by MTT assay. Cell cycle arrest was measured by flow cytometry (FCM). Cell morphology was observed by optical microscope. The anticarcinogenic mechanism of SECO was analyzed. Results SECO had promotive effect on the cell growth at lower concentration (≤40 ?mol/L) but inhibition effect at higher concentration (100 ?mol/L). ENL and END, however, showed significant inhibition effect at all tested concentrations (10~100?mol/L). The cell cycle progression was arrested at G2/M phase and apoptosis was observed by optical microscope. Conclusion Effect of SECO on the MCF-7 cell proliferation depends on its concentration. Inhibition effect of SECO may relate to its metabolites ENL or END.

AIM: Stable human macrophage-derived foam cell model is significant for the study on artherosclerosis. This study investigated the feasibility of establishing macrophage-derived foam cell model using U937 cell lines. METHODS: The experiment was performed at Institute of Basic Medicine, Chengde Medical College from March to September 2006. ①U937 cell lines were purchased from Institute of Biochemistry & Cell Biology, Chinese Academy of Sciences. ②Sixteen bottles of U937 cells (109 L-1) were incubated at 37 ℃ in saturated humidity containing 5% CO2 for 72 hours. Among them, eight bottles contained 100 ?g/L phorbol-12-myristate-13-acetate (PMA) and 100 mg/L low-density lipoprotein (LDL) as experimental group, and the other eight bottles only 100 mg/L LDL as control group. ③Cell morphology was studied under light microscope by Wright's and Oil red O staining. Cell total cholesterol (TC) was measured after 72 hours of incubation. RESULTS: A large amount of lipid droplets were found in the cytoplasm by Oil red O staining in cells of the experimental group, but not found in control group cells. TC in cells of the experimental group was significantly higher than in control group [(520.13?37.52), (39.47?9.26) mg/g, t=35.18, P

Background Diabetic macular edema (DME) is one of serious ocular complications of diabetes mellitus and is often treated by laser photocoagulation,peribulbar injection of triamcinolone acetonide (TA) and intravitreal injection of ranibizumab.However,some adverse responses occur in each approach.To seek a safe,effective and ecnomic therapy for DME is of clinical significance.Objective This study was to observe the safety and efficacy of post-sclera injection of TA with a self-made innovative device for DME and compare the outcome with peribulbar injection of TA and the intravitreal injection of ranibizumab.Methods A prospective non-randomized controlled study was performed.This study protocol was approved by Ethic Committee of Southwest Hospital of Third Military Medical University and complied with Helsinki declaration.Written informed consent was obtained from each patient before any medical treatment.Sixty eyes of 60 patients with DME were included in Southwest Hospital of Third Military Medical University from March 2013 to July 2016.The eyes were divided into post-sclera injection group,peribulbar injection group and intravitreal injection group,with 20 eyes for each group.TA at the dose of 20 mg was injected via posterior sclera with a self-made divice in the post-sclera injection group and via periphery of eyeball in the peribulbar injection group,and 0.5 mg ranibizumab was intravitreally injected in the intravitreal injection group.Best corrected visual acuity (BCVA) was examined and retinal thickness at macular area was measured by OCT in 1 month and 3 months after injection respectively.The outcome and complication were grouply compared.Results The BCVA was significantly improved 1 month and 3 months after injection in comparison with before injection in the post-sclera injection group and intravitreal injection group,and BCVA in the post-sclera injection group and intravitreal injection group was superior to that in the peribulbar injection group (all at P =0.000).No significant difference was found in post-injected BCVA between post-sclera injection group and intravitreal injection group (P =0.244,0.397).Retinal edema at macular area was gradually disappeared in the post-sclera injection group and intravitreal injection group and that in the peribulbar injection group was still visible after injection.The retinal thickness at macula was (321.85±31.98),(382.75±39.28) and (315.75 ± 40.43) μm at 1 month and was (311.95±32.73),(393.65±33.84) and (302.65±38.99) μm at 3 months after injection in the post-sclera injection group,peribulbar injection group and intravitreal injection group respectively,and the retinal thickness values at macula in the post-sclera injection group and intravitreal injection group were significantly lower than those in the peribulbar injection group (all at P =0.000).The decrease rate of retinal thickness was higher in the post-sclera injection group and intravitreal injection group than that in the peribulbar injection group at various time points after injection (all at P＜0.01).Conclusions The efficacy and safety of post-sclera injection of TA for DME are similar to intravitreal injection of ranibizumab,which are superior to peribulbar injection of TA.
