RESUMO
Objective:To investigate the effect of Suhuang Zhike Capsule on airway inflammation in patients with acute episode of allergic rhinitis and asthma syndrome.Methods:Eighty patients with allergic rhinitis and asthma syndrome were admitted to North China University of Science and Technology Affiliated Hospital from June 2016 to September 2017.A prospective cohort study was carried out and randomly divided into treatment group and control group with 40 patients in each group.The control group was treated with conventional anti-inflammatory, expectorant and antiasthmatic therapy, while the treatment group was treated with Suhuang Zhike Capsule.The changes of nasal symptoms and asthma clinical symptoms in the two groups were compared before and after treatment, and the changes of nitric oxide in exhaled air, eosinophils in blood and induced sputum were measured.Results:Compared with the control group, there was no significant difference in the number of eosinophils in the exhaled nitric oxide, eosinophil count in blood and induced sputum before treatment in the treatment group ((161.45±4.67)×10 -9 vs.(163.12±4.56)×10 -9, (1.59±0.53)×10 9/L vs.(1.60±0.51)×10 9/L, (1.11±0.06)×10 9/L vs.(1.18±0.09)×10 9/L; t values were 0.10, 0.44, 1.75, respectively, all P>0.05). After treatment, the exhaled nitric oxide, eosinophil count in blood and induced sputum in the treatment group were significantly lower than those before treatment((30.86±5.54)×10 -9 vs. (161.45±4.67)×10 -9; (0.32±0.05)×10 9/L vs. (1.59±0.53)×10 9/L; (0.06±0.02)×10 9/L vs. (1.11±0.06)×10 9/L, t values were 91.32, 41.63, 51.77, respectively, all P<0.01). In the treatment group, the effective rate of nasal symptom control was 85.0% (34/40) significantly higher than 62.5% (25/40) in the control group (χ 2=5.23, P<0.05), and the effective rate of asthma clinical symptom control was significantly higher than that in the control group(90.0%(36/40), 72.5%(29/40), χ 2=4.02, P<0.05). Conclusion:Suhuang Zhike capsule can obviously improve the airway inflammatory response of patients with allergic rhinitis asthma syndrome in the acute attack stage, and the combination of conventional treatment plan is helpful to improve the curative effect.

Objective:To observe the efficacy of the serial treatment with autologous hematopoietic stem cell transplantation after bortezomib and dexamethasone-based triple chemotherapy regimen and followed by lenalidomide and intermittent intensive therapy in primary plasma cell leukemia.Methods:A retrospective analysis was made on the clinical data of one patient who was diagnosed as primary plasma cell leukemia with complex karyotype in April 2018 in Henan Cancer Hospital, and the relevant literature was reviewed.Results:The patient received multiple cycles of bortezomib and dexamethasone-based triple chemotherapy regimen, then received autologous hematopoietic stem cell transplantation, lenalidomide and intermittent intensive therapy. The patient eventually achieved complete remission and the progression-free survival time was 18 months until the day before the deadline for this article.Conclusion:The treatment with autologous hematopoietic stem cell transplantation after bortezomib and dexamethasone-based triple chemotherapy regimen and followed by lenalidomide and intermittent intensive therapy may improve the prognosis of patients with primary plasma cell leukemia and prolong the survival time.
RESUMO
Objective@#To explore the effect of combination regimen of interferon alpha-1b, interleukin-2 and thalidomide (ITI regimen) on minimal residual disease (MRD) in patients with acute myeloid leukemia (AML) who were in hematologic remission but MRD-positive.@*Methods@#Eighteen patients (17 from Tumor Hospital of Zhengzhou University and 1 from the First People's Hospital of Pingdingshan City) with AML admitted from July 2016 to June 2018, who were in hematologic remission but MRD-positive were treated with different doses of ITI regimen, and the MRD levels were monitored.@*Results@#Among 18 patients who received a conventional dose of ITI regimen for 1 to 2 months, 7 patients had undetectable MRD, 3 had significant decrease in MRD levels, 3 had elevated MRD level and had hematologic recurrence. Three patients with elevated MRD level received a higher dose of ITI regimen, 2 of them turned to MRD negative and the other 1 patient had decreased MRD level. The total response rate was 72.2%, and the response rate in patients with MRD > 1.0% was 57.1% (4/7) , and that of patients with MRD < 1.0% was 81.8% (9/11) , respectively.@*Conclusion@#The ITI regimen can reduce the MRD level of patient with AML who are in hematologic remission but MRD-positive. The therapeutic effect could be improved by a higher dose administration of ITI regimen, and therapeutic effect may be negatively correlated with MRD level before treatment.
RESUMO
Objective To summarize the clinical characteristics,diagnosis,treatment and prognosis of EBV related post-transplantation lymphoproliferative diseases (PTLD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods The clinical data of 262 cases of allo-HSCT were retrospectively,and EBV-associated PTLD occurred in 9 cases after transplantation with a incidence of 3.44％ (9/262).Of the 9 patients,6 were males and 3 were females,with a median age of 19 years;the primary disease was severe aplastic anemia (SAA) in 6 cases,acute myeloid leukemia in 2 cases and chronic myeloid leukemia in 1 case Results The occurring median time of EBV associated PTLDs was 58 d (44-271 d).The clinical manifestations of most PTLD recipients were recurrent fever with no reaction to any antibiotics,antiadoncus and lymphadenectasis.Of the 9 recipients,6 cases obtained pathological diagnosis,and 3 cases clinical diagnosis.Superficial lymph node and central nervous system (CNS) involved in 8 and 4 recipients,respectively;lung and bone involvement occurred in 2 recipients and 1 case,respectively.The median number of peripheral blood EBV DNA in 9 recipients was 7.21 × 104 copies/ml (6.37 × 103-4.56 × 105 copies/ml) at the time of onset.EBV DNA in peripheral blood was positive in only one ease of 4 CNS recipients.Among 9 recipients after therapy,4 cases were cured and 4 cases were partially effective,and 1 recipient was ineffective After follow-up for 28 months (2-48 months),6 cases died,and 3 survived.Conclusion Incidence of EBV related PTLD in SAA patients undergoing allo-HSCT is relatively higher than leukemia recipients.Reduction or withdrawal of immunosuppressant,Rituximab and low dose of DLI is effective treatment.
RESUMO
To explore the efficacy and influencing factors of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with myeloid leukemia and granulocytic sarcoma (GS).Clinical outcome including hematopoietic reconstitution,transplant-related complications,survival and relapse were collected and retrospectively analyzed in 9 patients with myeloid leukemia and GS after allo-HSCT.Hematopoiesis reconstitution was achieved in all the 9 recipients.Four cases developed acute graft-versus-host disease (GVHD),and 1 with chronic GVHD.The median follow-up time after transplantation was 10(4-81) months.Only 2 cases survived,the other 7 died of relapse.The median time of relapse after transplantation was 5(3-19) months.Allo-HSCT is relatively effective treatment for patients with myeloid leukemia and GS.Relapse after transplantation remains the major factor of mortality.
RESUMO
Objective To assess the effectiveness of unrelated donor (URD) allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the treatment of severe aplastic anemia (SAA),and the difference between URD allo-HSCT and matched sibling donor (MSD) allo-HSCT.Methods According to the source of donors,the SAA patients subject to allo-HSCT were divided into MSD allo-HSCT group (MSD group) and URD allo-HSCT group (URD group) from October 2001 to December 2016 in Henan Cancer Hospital.The efficacy and transplantation related complications were compared between two groups.Results There were no statistically significant differences in hematopoietic reconstitution and graft rejection between two groups.The incidence of grade Ⅱ-Ⅳ acute GVHD and chronic GVHD was higher in the URD group than in the MSD group (30.76％ vs.8.57％,P =0.026;26.92％ vs.5.71％,P =0.021).However,other transplant-related complications including pulmonary complications and hemorrhagic cystitis,incidence of EBV and CMV reactivation and venous occlusive disease showed no significant difference between two groups.The estimated 5-year over survival was (73.6 ± 8.7) ％ in the MSD group and (72.7 ± 9.5) ％ in the URD group (P =0.878).There was no significant difference in 5-year disease-free survival between two groups (73.6 ± 8.7％ vs.70.3 ± 10.2,P =0.668).Conclusion URD-HSCT is a novel treatment approach and could be considered as first-line therapy in selected patients without MSD.
RESUMO
Objective To investigate the effects of β-adrenoceptor (β-AR) activation on the apoptosis in human mesangial cells and it's mechanism.Methods Cultured HMC were used in experiments and were divied into four groups:the control group; β-AR activation (β-AR agonist NE/Pra) group; β-AR inhibitor (Prop) group; antioxidants group.The experiments technology including PCR,confocal scanning microscope,immunofluorescence and Tunel.Results The results of RTPCR and confocal scanning microscope showed that β1-AR and β2-AR were expressed in human HMC.β-AR activation induced reactive oxygen species (ROS) increase in human MCs,the relative levels of ROS were elevated as early as 0.5 h after β-AR activation,and gradually increased and peaked at 4 h on a concentration and time dependent manner.Tunel results demonstrated that β-AR activation induced apoptosis with ROS on a concentration and time dependent manner,β-AR blocking agent-propranolol significantly inhibited β-AR activation induced apoptosis.Antioxidants including vitamin C and NAC could inhibited β-AR activation induced apoptosis (all P ＜ 0.01).Conclusions β-AR is functionally expressed in human mesangial cell,furthermore β-AR activation-induced ROS increase mediate apoptosis.Antioxidants can inhibit β-AR activation induced apoptosis.
RESUMO
Objective To explore teaching effectsof biochemistry by comparingthe traditional teaching with the network investigative teaching. Methods 425 five-year-program students of clinical medicine of grade 2012 were chosen as subjects, with 246 students from Classes 5-8 as experimental group in which network investigative teaching was implemented andwith 179 students of Classes 17-20 as the control group which wasgiven traditional teaching. After the teaching , the teaching effects were evaluated through a questionnaire and the test scores of the two groups were compared and statistically analyzed. The two groups were compared by using t test. Results More than 70% of students in the experimental groups were generally satisfied with several aspects of the network investigative teaching and gavea good evaluation. The experimental group students' total scores and every item scores were all higher than the control group students', in which the practise scores and the case analysis problem scores had significant differences by statistical analysis with P values being 0.000 and 0.002, respec-tively. Conclusion Network investigative teaching is better than traditional teaching in the teaching of biochemistry , which can enhance students' ability of problem analysis and their enthusiasm for learning.
