ABSTRACT

Objective To evaluate the effect of clinical pharmacists participating in the treatment of hospitalized patients with diabetic foot by antibiotics management index and health economics index. Methods 40 hospitalized patients with diabetic foot of Wagner Grade 4 in the Endocrine Department of Air Force Medical Center from April to September 2017 were selected as control group, and 40 hospitalized patients with diabetic foot of Wagner Grade 4 in the Endocrine Department from April to September 2019 were selected as interventional group. No clinical pharmacists were involved in drug treatment of patients in the control group, while the clinical pharmacists in the interventional group participated in drug treatment, and implemented antimicrobial stewardship, medication reconciliation, pharmaceutical care and medication education. Antibiotics management indexes (use intensity of antibiotics, use rate of special class antibiotics) and health economics indexes (medicine expenses, hospitalization expenses) of the two groups were compared. Results The efficacy of the two groups was similar. The use intensity of antibiotics and use rate of special class antibiotics of the interventional group in which clinical pharmacists participated were significantly lower than the control group (P<0.01), so were the medicine expenses and hospitalization expenses (P<0.01). Conclusion Clinical pharmacists participating in the treatment of hospitalized patients with diabetic foot could reduce antibiotics administration index and health economics index, promote rational medicine use and save medical expenses.

ABSTRACT

OBJECTIVE To study the effects of self-assembled nanoparticles from Shaoy ao gancao decoction (SGD-SAN)on the in vitro release and intestinal absorption of the main components of Glycyrrhiza uralensis . METHODS Gancao single decoction (GSD),Shaoyao single decoction (SSD),mixed suspension of Shaoyao and Gancao single decoction (MSSGD)and SGD (i.e. Shaoyao-Gancao decoction )were prepared ,and SAN was characterized. HPLC method was adopted to determine the contents of 7 main components (liquiritin apioside , liquiritin, isoliquiritin apioside , isoliquiritin, liquiritigenin, glycyrrhizic acid , isoliquiritigenin)in G. uralensis . The dialysis bag method was used to investigate the effects of the formation of SGD-SAN on in vitro release of 7 main components in G. uralensis with pH 1.2 HCl solution and pH 6.8 phosphate buffered solution (PBS)as release media. Single-pass intestinal perfusion study was performed to investigate the effects of the formation of SGD-SAN on the intestinal absorption of 7 main components from G. uralensis . RESULTS SAN with particle size of 200-300 nm and polydispersity index of 0.3-0.5 was found in GSD ,MSSGD and SGD. GSD-SAN and MSSGD-SAN were in rod shape while SGD-SAN was irregularly spherical under transmission electron microscope. The results of in vitro release study showed that the formation of SGD-SAN could significantly increase in vitro release of liquiritigenin ,isoliquiritigenin and glycyrrhizic acid ,and had no effect on other components of G. uralensis in pH 1.2 HCl solution. The formation of SGD-SAN also had no effect on the release of each component from G. uralensis in pH 6.8 PBS. The results of intestinal perfusion experiments showed that the formation of SGD-SAN could significantly promote the absorption of each component from G. uralensis in the ileum. CONCLUSIONS- The formation of SGD-SAN significantly improves the in vitro release of poorly soluble components from G. uralensis and promotes the intestinal absorption of main components from G. uralensis ,which is the physical structure basis for the compatibility and synergy of Paeonia lactiflora and G. uralensis .

ABSTRACT

Objective@#To analyze the efficacy of HLA-haploidentical peripheral hematopoietic stem cell transplantation (haplo-PBSCT) following reduced intensity conditioning (RIC) regimen to treat the patients with hematological malignancies who were older than 50 years old.@*Methods@#Eighteen patients with hematological malignancies over 50 years were enrolled, including 8 male and 10 female patients. The median age of all patients was 52 (range: 50–66) years. Of them, 8 patients had acute myeloid leukemia (AML) , 2 chronic myelocytic leukemia (CML) , 5 myelodysplastic syndrome (MDS) , 2 acute lymphoblastic leukemia (ALL) , and 1 aggressive natural killer cell leukemia (ANKL) . All patients received fludarabine, cytarabine and melphalan with rabbit anti-human thymocyte globulin (FAB+rATG regimen) and transplanted with high dose non-T cell-depleted peripheral hematopoietic stem cells from donors. Enhanced graft versus host disease (GVHD) prophylaxis and infection prevention were administered.@*Results@#Fifteen days after transplantation, 16 patients achieved complete donor chimerism. One of them rejected the donor graft completely at thirty days after transplantation, and the other 2 patients had mixed chimerism 15 days after transplantation and converted to complete recipient chimerism at 30 days after transplantation. The cumulative incidence of acute GVHD (aGVHD) was 61.1% (95%CI49.6%-72.6%) . The incidence of grade Ⅱ-Ⅳ aGVHD was 35.4% (95%CI 21.1%-49.7%) , whereas grade III-IV was 13.8% (95%CI 4.7%-22.9%) . The 2-year cumulative incidence of chronic GVHD (cGVHD) rate was estimated at 38.2% (95%CI 25.5%-50.9%) . Patients were followed-up for a median of 14.5 months (range, 3-44 months) . The Kaplan Meier estimates of 2-year overall survival (OS) and disease-free survival (DFS) was 72.6% (95%CI 60.1%-85.1%) and 63.7% (95%CI 49.2%-78.2%) , respectively. The 2-year cumulative incidence of relapse and non-relapse-mortality (NRM) was 31.2% (95%CI 16.5%-45.9%) and 12.5% (95%CI 4.2%-20.8%) , respectively.@*Conclusion@#RIC-haplo-PBSCT protocol can achieve better results in patients with hematologic malignancies over 50 years old.

ABSTRACT

OBJECTIVE: To investigate the effects of crystal form on in vivo and in vitro behavior of Astilbin nanosuspensions (AT-NS). METHODS: AT-NS1 and AT-NS2 were prepared by precipitation method and miniaturized media milling method respectively. The particle size and polydispersity index (PDI) were determined by laser particle size analyzer. X-ray diffraction (XRD), scanning electron microscopy (SEM), HPLC and paddle method were used to analyze and compare the structure characteristics, appearance morphology and in vitro dissolution of AT raw material, AT-NS1 and AT-NS2. Totally 15 healthy male SD rats were randomly divided into AT raw material, AT-NS1 and AT-NS2 group, with 5 rats in each group. They were given relevant medicine suspension 120 mg/kg (using water as solvent) intragastrically; blood samples  were collected from orbit before medication (0 min) and 5, 10, 20, 30, 60, 120, 240, 480 min after medication. Using rutin as internal standard, HPLC method was used to determine plasma concentration of AT in rats. Pharmacokinetic parameters were calculated by using DAS 2.0 software and then compared. RESULTS: The particle sizes of AT-NS1 and AT-NS2 were (212.48±0.32) nm and (226.36±2.29) nm, respectively; PDI were 0.129 3±0.026 3 and 0.254 7±0.012 4. XRD analysis showed AT-NS1 was amorphous, and AT-NS2 was crystalline. Diffraction peaks of both were different from those of AT raw material. SEM analysis showed that AT-NS1 and AT-NS2 were similar in morphology, and they were spherical and uniform in size; AT raw material was lump with large particle size and different sizes. Results of dissolution tests showed that accumulative dissolution of AT raw material, AT-NS1 and AT-NS2 were 4.54%, 35.01%, 12.22% at 1 h; accumulative dissolution of them were 24.01%, 81.14%, 64.69% at 12 h; accumulative dissolution of them were 36.04%, 84.47%, 85.86% at 24 h, respectively. Results of pharmacokinetic study showed, compared with AT raw material group, cmax and AUC0-∞ of AT-NS1 and AT-NS2 groups as well as t1/2z of AT-NS1 group were increased significantly, while tmax of AT-NS1 group was significantly reduced significantly (P<0.05). Compared with AT-NS2 goup, cmax, AUC0-∞ and t1/2z of AT-NS1 group were increased significantly, while tmax was reduced significantly (P<0.05). CONCLUSIONS: When AT is prepared into NS, dissolution in vitro and oral absorption in vivo of AT are increased significantly. In a short time, the dissolution/absorption of amorphous NS is faster than crystalline NS.

ABSTRACT

Background and purpose:T-cell non-Hodgkin’s lymphoma(T-NHL) has relatively high incidence in Asian countries, and the incidence rate showed an upward tendency. It has a dual characteristic of both ethnic and regional. We conducted this study in order to analyze the clinical characteristics, pathological type and survival of T-NHL in our hospital. Methods:Records of 50 cases with T-NHL treated from Jan. 2002 to Dec. 2012, were analyzed in terms of clinical characteristics, distribution of pathological type and survival. Results:Patients with T-NHL account for 24%of NHL cases in our study. Of the 50 cases, 37 were Han, 13 were Uygur;The most frequent type was NK/T cell lymphoma(NK/TCL)(16/50, 32%). We performed pathological type for each age group:4 cases with children’s group were all T-lymphoblastic leukemia/lymphoma(T-LBL)(4/4,100%), the most frequent type of youth and middle age group was NK/TCL(8/20, 40%;7/13, 53.8%), as the senile group was angioimmunoblastic T-cell lymphoma(AITL)(6/13, 46.2%). There was also a signiifcant difference in pathological type between the stage, with stageⅠ-Ⅱwere all NK/TCL(12/12, 100%), stageⅢ-Ⅳwere observed with peripheral T-cell lymphomas-unspeciifed(PTCL-U)(9/38, 23.7%) and AITL(9/38, 23.7%). The frequent type of Han was NK/TCL(14/37, 37.8%), as the Uygur was T-LBL(5/13, 38.5%). The median overall survival(OS) time was 12 (ranged 0-112) months. The 5 year OS rate was 39%. Both pathological type and age group were important factors influencing survival. The difference in outcome for the pathological type(P<0.05): NK/TCL and anaplastic large cell lymphoma(ALCL) had the better 3 year OS rates(71%, 61%), but PTCL-U and T-LBL had poor prognosis(19%, 7%). Age did a signiifcant effect on OS(P<0.05):children’s group had the worse 5-year OS rate (0%), middle age group had a better prognosis (67%), the OS of the youth group was 35%, for the senile group was 21%. Conclusion:T-NHL in Xinjiang region have their unique clinical characteristics:The overall incidence rate was similar with the domestic report, however, higher than the reports abroad. The incidence of Han was higher than Uygur. Pathological type showed in this study was different from that in European and American countries. There was a significant difference in distribution of pathological type in different age group, stage and nation. The long-term survival and prognosis of patients in Xinjiang region was poor. Both pathological type and age group were important factors inlfuencing survival.

ABSTRACT

Objective To explore the clinical outcome of HLA haploidentical vs HLA-matcbed peripheral blood hematopoietic stem cell transplantation (PBSCT) without in vitro T-cell depletion for malignant hematological diseases. Methods 111 patients with malignant hematological diseases underwent PBSCT without in vitro T-cell depletion between May 2004 and February 2009, including 51 patients with HLA-haploidentical and 60 patients with HLA-matched. All patients have received myeloablative conditioning regimen. A two-agent based graft-versus-host disease (GVHD) prophylaxis was used as cyclosporine A and a short course of methotrexate. Mycophenolate mofetile was added for the patients with one locus mismatch. Mycophenolate mofetile, antithymocyte globulin and CD25 monoclonal antibody were added for the patients with 2-3 loci mismatch. The grafts were granulocyte colony-stimulating factor-mobilized peripheral blood stem cells without in vitro T-cell depletion. Results 111 patients achieved sustained and full donor-type engraftment. The median time to reach an absolute neutrophil count above 0.5×10~9/L was 14 days and that to a platelet count exceeding 20×10~9/L was 15 days in 51 HLA-haploidentical patients, and that was 12 days and 13 days in 60 HLA-matched patients, respectively. In 51 HLA-haploidentical patients, 25 patients developed aGVHD, including 20 cases of grade Ⅰ aGVHD, and 5 cases of grade Ⅱ. Thirty-three patients developed cGVHD with limited in 30 and extensive in 3. The 4-year cumulative incidence of cGVHD was 70.4 %. The 3-year probabilities of leukemia-free survival (LFS) were 74.5% (77.3 % for standard risk patients and 68.2 % for high risk patients respectively). Seven patients had recurrence. In 60 HLA-matched patients, 14 patients developed aGVHD, including 10 cases of grade Ⅰ, 2 cases of grade Ⅱ and 2 cases of grade Ⅲ. Thirty-seven patients developed cGVHD with limited in 32 and extensive in 5. The 4-year cumulative incidence of cGVHD was 58.1%. The 3-year probabilities of LFS were 72.1% (77.6 % for standard risk patients and 52.7 % for high risk patients respectively). Ten patients had recurrence. The incidence of aGVHD in HLA-haploidentical cohort was significantly higher than in HLA-matched cohort (P<0.05). There was no significant difference in incidence of cGVHD, incidence of relapse and LFS between HLA-haploidentical and HLA-matched cohorts (P>0.05). Conclusion Haploidentical PBSCT is feasible and safe for malignant hematological diseases to use myeloablative conditioning regimen in combination with intensive immunosuppressants without in vitro T cell depletion.

ABSTRACT

To explore the new pattern of Chinese medicine solid preparations (CMSP) in vitro dissolution, a method testing the bio-thermal activity in combination with UPLC was used. Microcalorimetry was used to obtain the characteristic metabolic growth power-time curves and a series of biothermodynamic parameters of the inhibition of Staphylococcus aureus by Yinhuang tablet dissolving solutions at the pH 6.8 (phosphate buffer) dissolution medium at different times. From these results, the cumulative dissolution of Yinhuang tablet based on bio-thermal activity was obtained. The dissolution rates of two components of chlorogenic acid and baicalin were determined by UPLC method. Then f2 similar factor method was used to evaluate the relevance of these two methods. The result showed that f2 values all were more than 50, indicating that there is a good correlation between the two methods of measuring the dissolution rate. It is feasible to determine CMSP in vitro dissolution by using bio-thermal activity, and to provide new evaluation methods for controlling the quality of CMSP.

ABSTRACT

BACKGROUND: Lack of human leucocyte antigen-matched family donors has restricted the application of hematopoietic cell transplantation. Due to immunological disorder of humam leucocyte antigen misfit, common way for haploidentical transplantation is associated with poor engraftment and severe graft-versus-host disease. Because not every patient has HLA-Jdentical family member, a substantial proportion of patients will receive haploidentical transplantation. OBJECTIVE: To explore the curative effect on malignant hematological diseases of haploidentical peripheral blood stem cell transplantation (PBSCT) using myeloablative conditioning regimen in combination of proper immunosuppressants without in vitro T-cell depletion. DESIGN, TIME AND SETTING: A case observation was performed at the Department of Hematology in the First Affiliated Hospital of Xinjiang Medical University from July 2002 to June 2008. PARTICIPANTS: Forty-two patients with malignant hematological diseases, including 29 standard-risk patients and 13 high-risk patients, age from 10 to 48 years, were transplanted with cells from a haploidentical family donor with 1-3 mismatched loci of HLA antigens. Seven patients had 1 locus mismatched donors and thirty-five patients had 2-3 loci mismatched donors. METHODS: The patients have received myeloablative conditioning regimen. A two-agent based graft-versus-host disease (GVHD) prophylaxis was used as cyclospodne A and a short course of methotrexate. Mycophenolate mofetile was added for 1 locus mismatched patients. Mycophenolate mofetile, antithymocyte globulin and CD25 mono-colonal antibody were added for 2-3 loci mismatched patients. The grafts were granulocyte colony-stimulating factor-mobilized peripheral blood stem cells without in vitro T-cell depletion. MAIN OUTCOME MEASURES: Engraftment, GVHD incidence and severity, relapse and leukemia-free survival and the immune function of patients in months 1, 3, 6, 12 and 18 postoperatively. RESULTS: Totally 42 patients achieved complete and sustained donor-type engraftment. Nineteen patients developed acute GVHD, the 2-year cumulative incidences of acute GVHD were 50.8%, gradeⅠ acute GVHD occurred in 16 cases and grade Ⅱ in 3 cases. Thirty-one patients were followed up more than 6 months, 23 of them developed chronic GVHD with limited in 20 and extensive in 3, the 2-year cumulative incidences of chronic GVHD were 57.1%. No patients died of GVHD. There were no significant differences in the reduction and recovery of T cells and B cells between HLA haploidentical PBSCT without in vitro T cell depletion and HLA-matched PBSCT. CONCLUSION: Haploidentical PBSCT is feasible and safe for malignant hematological diseases to use myeloablative conditioning regiment combination of intensive immunosuppressants without in vitro T cell depletion. A large amount of clinical cases need to be investigated in the near future.

ABSTRACT

The patterns of efficient components recognition and quality control for Chinese materia medica (CMM) have been the difficult and hot topics for CMM modernization.To get a radical and significant breakthrough in the investigation on the efficient component recognition and quality control standard for CMM,a tentative idea about efficient component recognition and quality control pattern for CMM based on constituent knock-out/knock-in is initially proposed in this article on the foundation of retrospective and prospective analyses.And its main aim is to provide some creative and practical ideas and methods to recognize the key efficient components of CMM precisely and quickly,and to meet with the requirements that the quality control standards for CMM will be effectiveness-related,quantitative and accurate,controllable and assessable.
