RESUMO
Objective@#To explore the effects of community building environment and sports with fitness APP usage and their interactions on teachers exercise habits in the Yangtze River Delta Region, so as to provide a scientific basis for the development of a sports and health promotion intervention program for teachers.@*Methods@#A total of 2 530 in service teachers from four provinces and cities in the Yangtze River Delta region, namely, Shanghai, Zhejiang, Jiangsu and Anhui Province, were sampled in May-June 2023 by using convenient cluster random sampling method. Self designed questionnaire was used to collect the basic information of the surveyed teachers, Physical Activity Building Environment Evaluation Questionnaire and the Sports with Fitness APP Usage Questionnaire were used to measure the teachers subjective perception of the community building environment and the usage of sports with fitness APP, respectively. Physical Exercise Habituation Scale was used to assess the level of exercise habits. Logistic regression models were applied to analyze the effects of community building environment and sports with fitness APP usage on physical exercise, and the interaction effects were analyzed by using additive and multiplicative models.@*Results@#Among all the teachers surveyed, 658 of them reported good physical exercise habits (26.0%), and differences in the rate of physical activity habit formation by gender, age, years of teaching, as well as subject of teaching were statistically significant ( χ 2=42.94, 39.73, 35.47, 218.23 , P <0.05). Teachers with physical exercise habits had significantly higher community building environment scores and sports and fitness APP use than teachers without exercise habits ( t =12.17,16.54, P <0.05). Adjusting for the confounders of age, gender, years of teaching experience, and subjects taught, multifactorial unconditional Logistic regression analysis showed that the probability of teachers having good physical exercise habits increased by 22% for every 1-point increase in the community building environment score on average ( OR =1.22, 95% CI =1.11-1.40), and the probability of teachers having good physical exercise habits increased by 16% for every 1-point increase in the sports with fitness APP score on average ( OR = 1.16 , 95% CI =1.03-1.31) ( P <0.05). Interaction analyses showed that there was an additive interaction between the effects of community building environment and sports and fitness APP use on teachers physical exercise habits after adjustment, and the 95% CI for RERI , API and SI were 1.17 -1.65, 0.12-0.46 and 1.78-3.33 ( P <0.05), respectively, and there was no multiplicative interaction ( P >0.05).@*Conclusions@#The community building environment and the usage of sports & fitness APP show impacts in the formation of teachers physical exercise habits in the Yangtze River Delta region, and there is an interaction effect. Enhancing the construction of smart sports centers around the community can provide a high quality external environment for the physical exercise habits formation.
RESUMO
Objective@#To explore the efficacy and prognostic factors of hematopoietic stem cell transplantation (HSCT) for the treatment of patients with anaplastic large cell lymphoma (ALCL) .@*Methods@#The clinical records of 33 ALCL patients after HSCT were collected and analyzed retrospectively to evaluate the rates of overall survival (OS) and recurrence after autologous (auto-HSCT) and allogeneic HSCT (allo-HSCT) and the factors influencing prognosis.@*Results@#The median-age of this cohort of 33 ALCL cases at diagnosis was 31 (12-57) years old with a male/female ratio of 23/10, 24 cases (72.7%) were ALK+ and 9 ones (27.3%) ALK-. Of them, 25 patients (19 ALK+ and 6 ALK-) underwent auto-HSCT and 8 cases (5 ALK+ and 3ALK-) allo-HSCT with a median follow-up of 18.7 (4.0-150.0) months. Disease states before HSCT were as follows: only 6 patients achieved CR status and received auto-HSCT, 16 patients achieved PR (14 cases by auto-HSCT and 2 ones allo-HSCT) , the rest 11 cases were refractory/relapse (5 cases by auto-HSCT and 6 ones allo-HSCT) . There were 7 cases died of disease progression (5 after auto-HSCT and 2 allo-HSCT) and 5 cases treatment-related mortality (TRM) (2 after auto-HSCT and 3 allo-HSCT) , TRM of two groups were 8.0% and 37.5%, respectively. Both the median progression-free survival (PFS) and OS were 15 months after auto-HSCT, the median PFS and OS after allo-HSCT were 3.7 (1.0-90.0) and 4.6 (1.0-90.0) months, respectively. There was no statistically significant difference in terms of survival curves between the two groups (OS and PFS, P=0.247 and P=0.317) . The 2-year OS rates in auto-HSCT and allo-HSCT groups were 72% and 50%, respectively. The 5-year OS rates in auto-HSCT and allo-HSCT groups were 36% and 25%, respectively.@*Conclusion@#ALCL treated by chemotherapy produced high rates of overall and complete responses. Chemotherapy followed by auto-HSCT remained to be good choice for patients with poor prognostic factors. High-risk patients should be considered more beneficial from allo-HSCT.
RESUMO
Objective@#To evaluate clinical outcomes of autologous (auto-HSCT) and allogeneic hematopoietic stem cell transplantation (allo-HSCT) for angioimmunoblastic T-cell lymphoma (AITL) .@*Methods@#From June 2007 to June 2017, clinical data of AITL patients who underwent HSCT in eight hospitals were assessed retrospectively.@*Results@#Of 19 patients, 13 male and 6 female with a median age of 50 (32-60) years old, 12 auto-HSCT and 7 allo-HSCT recipients were enrolled in this study, all donors were HLA-identical siblings. Two of allo-HSCT recipients were relapsed auto-HSCT ones. There were 5 patients (5/12) in complete response (CR) status and 7 (7/12) in partial remission (PR) status before transplantation in auto-HSCT group, and 2 (2/7) in PR status and 3 (3/7) in progression disease (PD) status before transplantation in allo-HSCT group. The median follow-up for the surviving patients was 46.5 months (range, 1-100 months) for the whole series, two patients lost in auto-HSCT group. Three patients developed acute graft-versus-host disease (aGVHD) and 5 chronic graft-versus-host disease (cGVHD) after allo-HSCT. Three patients died of primary disease and 1bleeding in auto-HSCT group. One patient died of primary disease and 2 transplantation-related mortality in allo-HSCT group. The 3-year cumulative overall survival (OS) were 56% (95%CI 32%-100%) and 57% (95%CI 30%-100%) for auto-HSCT and allo-HSCT, respectively (P=0.979) . The 3-year cumulative progression-free survival (PFS) were 34% (95%CI 14%-85%) and 57% (95%CI 30%-100%) for auto-HSCT and allo-HSCT, respectively (P=0.451) .@*Conclusion@#Both auto-HSCT and allo-HSCT were optimal choices for AITL. In clinical practice, which HSCT was better for AITL patients should be based on comprehensive factors including sensitivity to chemotherapy, risk stratification and disease status at transplantation.
RESUMO
Objective@#To observe the efficacy and safety between Pegfilgrastim (PEG-rhG-CSF) and Recombinant human granulocyte colony stimulating factor (rhG-CSF) in hematological malignancy after allogeneic hematopoietic stem cell transplantation (allo-HSCT) .@*Methods@#157 patients after allo-HSCT were enrolled in this study from June 2015 to November 2016. Two agents of G-CSF were used to stimulate hematopoietic recovery after transplantation. There were 65 cases in PEG-rhG-CSF and 92 cases in rhG-CSF groups. Patients in PEG-rhG-CSF group were given a single subcutaneous dose of 6 mg on the first day and +8 d, while cases in rhG-CSF group were given in dose of 5 μg·kg-1·d-1 by subcutaneous injection from +1 d continuing to neutrophils more than 1.5×109/L, and then the indicators and survival rates in two groups after transplantation were compared.@*Results@#①There were no significant differences of the neutrophil implantation time[13.5 (8-12) d vs 13 (9-24) d, P=0.393] and platelet implantation time [14 (9-160) d vs 14 (9-92) d, P=0.094] between PEG-rhG-CSF and rhG-CSF groups respectively. There were no significant differences in terms of neutropenia period (P=0.435) , number of cases who got fever during neutropenia (P=0.622) , and the median time of fever in neutropenia period (P=0.460) , respectively between the two groups. There were no significant differences of erythrocyte and platelet transfusions (P=0.074, P=0.059) within 1 month after transplantation. ②There were no significant differences with regard to the incidences of acute GVHD[23.1% (15/65) vs 34.8% (32/92) , P=0.115], chronic GVHD[20.0% (13/65) vs 32.6% (32/92) , P=0.081], Ⅱ-Ⅳdegree of acute GVHD[30.0% (13/65) vs 30.4% (30/92) , P=0.287] and extensive chronic GVHD[9.2% (6/65) vs 20.7% (19/92) , P=0.135] between PEG-rhG-CSF and rhG-CSF groups. ③There were no significant differences in terms of disease free survival (DFS) (62.5% vs 61.4%, P=0.478) and overall survival (OS) (67.4% vs 67.3%, P=0.718) between PEG-rhG-CSF and rhG-CSF groups. ④There was no significant difference of the non-relapse mortality (NRM) between PEG-rhG-CSF and rhG-CSF groups[20.5% (95%CI 11.4%-37.0%) vs 32.6% (95%CI 22.2%-47.9%) , P=0.141]. The relapse rate was not statistically significant[14.9% (95%CI 7.4%-29.8%) vs 10.0% (95%CI 5.0%-20.0%) , P=0.299].@*Conclusion@#Compared with rhG-CSF, PEG-rhG-CSF could reduce the times of injection. There were no differences in terms of hematopoietic recovery, the incidence of GVHD, relapse rate, DFS and OS rates after allo-HSCT between two groups.
RESUMO
Objective@#To analyze the efficacy of recombinant activated factor Ⅶ a (rF Ⅶ a) on hematonosis with moderate or severe bleeding signs.@*Methods@#Of total 16 cases with rF Ⅶ a treatment from May 2013 to May 2016, 8 cases received allogeneic hematopoietic stem cells transplantation (allo-HSCT) and the other were non-transplantation patients. In two groups, there was no significant difference on rF Ⅶ a usage and dosage. 15 patients with acute graft-versus-host disease (aGVHD) after allo-HSCT were control group (without rF Ⅶ a) .@*Results@#①The total response rate was 75.0% (6/8) in non-transplantation group and 37.5% (3/8) in transplantation group, respectively. Median interval for hemorrhage stop was 38.5 hours in non-transplantation group and 63.0 hours in transplantation group. The median overall survival (OS) was 201.0 and 29.0 days for non-transplantation group and transplantation group, respectively, and the OS rate was 50.0% (4/8) and 25.0% (2/8) , respectively. The bleeding-related mortality rate was 50.0% (2/4) and 83.3% (5/6) , respectively. ②Of the 16 cases, 9 showed response to rF Ⅶ a treatment and the other 7 cases’bleeding signs did not alleviate. The median OS was 268.0 in 9 cases with response and 24.0 days in 7 cases without response, respectively. ③In patients with intestinal aGVHD complicated with intestinal hemorrhage, the median OS of observation group (n=6) and control group (n=15) were 25.5 days and 20.0 days, respectively.@*Conclusion@#Patients with hematological diseases, especially patients after allo-HSCT, had high bleeding-related mortality, and rFⅦa therapy had a obvious hemostatic efficacy. The survival rate of patients with response was higher than that of cases without response. The causes of poor hemostasis efficacy of rF Ⅶ a therapy were associated with unsatisfactory control of complications in patients with intestinal bleeding after allo-HSCT.
RESUMO
<p><b>BACKGROUND</b>Steady-state bone marrow (SS-BM) and granulocyte colony-stimulating growth factor-primed BM/peripheral blood stem-cell (G-BM/G-PBSC) are the main stem-cell sources used in allogeneic hematopoietic stem-cell transplantation. Here, we evaluated the treatment effects of SS-BM and G-BM/G-PBSC in human leucocyte antigen (HLA)-identical sibling transplantation.</p><p><b>METHODS</b>A total of 226 patients (acute myelogenous leukemia-complete remission 1, chronic myelogenous leukemia-chronic phase 1) received SS-BM, G-BM, or G-PBSC from an HLA-identical sibling. Clinical outcomes (graft-versus-host disease [GVHD], overall survival, transplant-related mortality [TRM], and leukemia-free survival [LFS]) were analyzed.</p><p><b>RESULTS</b>When compared to SS-BM, G-BM gave faster recovery time to neutrophil or platelet (P < 0.05). Incidence of grade III-IV acute GVHD and extensive chronic GVHD (cGVHD) was lower than seen with SS-BM (P < 0.05) and similar to G-PBSC. Although the incidence of cGVHD in the G-BM group was similar to SS-BM, both were lower than G-PBSC (P < 0.05). G-BM and G-PBSC exhibited similar survival, LFS, and TRM, but were significantly different from SS-BM (P < 0.05). There were no significant differences in leukemia relapse rates among the groups (P > 0.05).</p><p><b>CONCLUSIONS</b>G-CSF-primed bone marrow shared the advantages of G-PBSC and SS-BM. We conclude that G-BM is an excellent stem-cell source that may be preferable to G-PBSC or SS-BM in patients receiving HLA-identical sibling hematopoietic stem-cell transplantation.</p>

<p><b>OBJECTIVE</b>To investigate the efficacy of allogeneic hematopoietic stem cell transplantation（allo-HSCT）in the treatment of patients with Ⅲ,Ⅳ non-Hodgkin lymphoma（NHL）, and compared the efficacy between Cy- fractionated to talbody irradiation（fTBI）based conditioning regimen and Maryland, horse flange and mitoxantrone（BMM）.</p><p><b>METHODS</b>The clinical data of 47 patients with Ⅲ, Ⅳ NHL after allo- HSCT from November 1998 to May 2014 were collected and retrospectively analyzed. To observe the hematopoietic reconstruction recovery after transplantation, cumulative incidence of acute graft- versus- host- disease （aGVHD） and chronic graft- versus- host- disease （cGVHD）, transplantation related mortality （TRM）, recurrence rate （RR）, disease- free survival （DFS）, overall survival（OS）. Compare the efficacy of fTBI and BMM conditioning regimen at the same time.</p><p><b>RESULTS</b>Neutrophils achieving 0.5×10⁹/L and platelets achieving 50×10⁹/L on day 17 （range, 10- 72） post transplantation. Acute GVHD occurred in 53.19%, among them, grade Ⅰ-Ⅱ occurred in 42.55%, grade Ⅲ-Ⅳ occurred in 10.65%, and cGVHD occurred in 21.28%. 21 patients were alive with a median follow up of 9.7 months（0.2-149.1 months）. Overall survival（OS）was 73.5%, 49.3%, 40.1% respectively in the first, third and fifth year in Cy-fTBI group; in BMM group it was 67.8%, 32.9% and 31.4% respectively, and disease-free survival（DFS）was 65.3%, 45.6%, 30.2% respectively in the first, third and fifth year. In Cy-fTBI group, the recurrence rate（RR）and transplantation related mortality（TRM）in the first year were 18.9%, 23.0% respectively, the third year were 19.5%, 38.3% and the fifth year were 35.2%, 39.2%. In BMM group, RR and TRM in the first year were 27.4%, 24.5% respectively, the third year were 38.9%, 46.4% and the fifth year were 39.2%, 48.2%. However, there was no significant difference in the indicator of OS, DFS, RR, TRM in the two groups.</p><p><b>CONCLUSION</b>Allo-HSCT could make some Ⅲ,Ⅳ NHL patients achieve long-term disease- free survival, but the TRM was still high relatively. Moreover, compared with the program of BMM conditioning regimen, Cy-fTBI might reduce the TRM and RR, meanwhile, increase the DFS and OS. However, due to the small number cases of two groups, there was no statistical significant difference.</p>

Aim To study the characteristics of the binding reaction of Troxetutin with bovine serum albumin (BSA) by fluorescence and ultra violet-visible absorption spectra.Methods The quenching mechanism of the fluorescence of BSA by troxerutin was studied with fluorescence.To determine the dynamic quenching constants and static binding constants,the Stern-Volmer equation and the double reciprocal Lineweaver-Burk equation were applied. The number of binding site was calculated with double logarithmic equation and the main binding force was discussed by thermodynamic equations. The binding distance and energy transfer efficiency between donor (BSA) and acceptor (troxerutin) were obtained effectively quenched fluorescence of BSA via static quenching processes. The binding constant Ka was calculated to be in the order of 106,indicating a strong interaction between Troxerutin and BSA. The number of binding site was approximately equal to 1,the binding distance was 1.97 nm,the energy transfer efficiency was 0.529,and the binding force was mainly hydrophobic force.Conclusion Troxerutin effectively quenchs the intrinsic fluorescence of BSA via static quenching mechanism,and the binding is mainly driven by the hydrophobic interaction.
RESUMO
The formula-factors concept was put forwarded in this article on account of the syndrome-factors theory. While the prescription compatibility principles "correspondence between syndrome and formula factors" was deduced form the differentiation of syndrome and treatment principles "correspondence between syndrome and formula". Founding on these concepts,the relation between "correspondence between syndrome and formula factors" and "principal,adjuvant,auxiliary and conductant ingredirnts" was approached on the prescription compatibility. And the result was that both compatibility principles above were interweaving associated for their supplementing each other. This conclusion was significative to the prescription compatibility theory as well as TCM clinical practice.

CMV related matrix protein pp65 antigenemia was screened in 100 Allo HSCT patients after transplantation. As control groups, samples from fourteen autologous HSCT patients, seventeen patients with various hematological malignant disorders, as well as twenty seven normal donors also were detected. CMV antigenemia was found in 91/100 Allo HSCT patients (91%) after transplantation. 56 % patients with antigenemia developed CMV disease. 54% patients developed acute GVHD. In 87 patients survived more than three months, 52 9% patients developed chronic GVHD. After follow up 18(4～36) months post transplantation, 21 patients died of CMV related diseases. Compared with autologous and non transplantation patients, CMV antigenemia and CMV diseases were particularly associated with Allo HSCT patients. It was obviously correlated with acute and chronic GVHD. CMV infection is a major factor affecting the clinical outcome of Allo HSCT patients.
RESUMO
Objective To observe the effects of ginkgolides on hypoxia tolerance in mice and on myocardial ischemia injury in rats.Methods The mice were given isoprenaline 20 mg/kg(ip) and the survival time of the mice model under the hypoxic condition was recorded. Rat myocardial ischemia was induced by subcutaneous injection of over- dosage isoprenaline(8 mg/kg). Before modeling, rats were pretreated with ginkgolides 10, 20, 40 mg/kg, of ginkgo biloba( EGb) Extract 300 mg/kg, Propranolol 5 mg/kg,or vehicle for four days. The histological changes of myocardiim, serum creatine phosphokinase (CPK) level and lactate dehydrogenase (LDH) activity, myocardial lactate dehydrogenase(LDH) and superoxide dismutase (SOD) content were detected.Results Ginkgolides could prolong the survival time in the mice under a hypoxic condition, lessen the isoprenaline- induced rat myocardial ischemia, inhibit the activities of serum CPK and LDH and the increase of MDA content in ischemic myocardial tissue, enhance superoxide dismutase (SOD) activity. Conclusion Ginkgolides enhance to hypoxia the tolerance in mice and prevent rats from myocardial ischemic injury. The protective mechanism may be related to its inhibition of the activity of platelet activating factor and oxygen free radical.
RESUMO
Aim To observe the change of NF-?B and expression of Bax and Bcl-2 related to apoptosis regulation in the cerebral infarction rat and study the protective effect of iridoid glycoside(IG) extracted from cornus officinalis on focal cerebral ischemia injury and its mechanism of action.Methods Rats were pretreated with drugs by mouth for 7 d and a focal cerebral infarction model of rat was induced by photochemical reaction.Immunohistochemistry and western blot were used to detect the change of expression of NF-?B,Bax and Bcl-2 in the cortex.Results Compared with control group,expression of NF-?B and Bax were increased while expression of Bcl-2 was decreased.Compared with model group,IG(IG 20、60、180 mg?kg~(-1)) markedly decreased the expression of NF-?B and Bax and increased expression of Bcl-2.Conclusion IG has therapeutical effect on cerebral infarction through regulating the expression of NF-?B and apoptosis related genes
