Objective To investigate the current status and awareness of pharmaceutical services in hospitals in Guizhou province and to provide a reference for exploring and carrying out pharmaceutical service fees.Methods The questionnaire was designed by the"wjx.cn"website.Three kinds of questionnaires were designed for pharmacists,doctors,nurses,and patients as the research objects,with corresponding differences in some questions,and promoted on WeChat,Dingxiangyuan,and other network platforms.Results A total of 655 questionnaires were collected,and 639 valid questionnaires were recovered,with an effective recovery rate of 97.56%.324 pharmacists(50.70%),82 doctors and nurses(12.83%),233 patients(36.46%)were surveyed.The average approval score of these three groups of respondents on pharmaceutical service fees was 4.67,4.23,and 4.22,respectively(full score:5).Conclusions Overall,pharmacists'professional services have received support from medical staff and patients.However,patients'pharmaceutical service projects currently focus on dispensing services.The recognition of pharmacists'work and the public's awareness of pharmaceutical services can be improved by enhancing the professional ability of pharmacists,strengthening publicity and guidance,and exploring"Internet+pharmaceutical services",etc.,to promote the sustainable development of pharmaceutical services.

Microcystin-leucine arginine (MC-LR), a potentially carcinogenic toxin, is produced by Cyanobacteria such as Microcystis and Ananabacteria during water bloom. Increasing evidence demonstrated that MC-LR induces male reproductive toxicity, mainly by inducing germ cell apoptosis, destroying cell cytoskeleton, interfering with DNA damage repair pathway, and damaging blood-testicular barrier (BTB), which eventually lead to male sterility. Testicular Sertoli cells are the somatic cells that directly contact with spermatogenic cells in seminiferous tubules. They not only regulate immune response to maintain testicular immune homeostasis by secreting a variety of cytokines and immunosuppressive factors, but also provide the protective effects of spermatogenic cells by forming BTB. MC-LR induces inflammation and apoptosis of Sertoli cells, and destroys the integrity of the BTB, and then causes spermatogenesis dysfunction.

Objective:To explore the clinical characteristics, diagnosis and treatment of acute leukemia patients during pregnancy.Methods:The clinical data of 16 cases with acute leukemia during pregnancy from January 2009 to December 2018 in the First Affiliated Hospital of USTC were retrospectively analyzed. The diagnosis and treatment regimens, pregnancy outcome, the early fetus and survival status of patients were also analyzed.Results:All 16 leukemia cases were confirmedly diagnosed and classified by bone marrow puncture, including 13 cases of acute myeloid leukemia (5 cases of non-acute promyelocytic leukemia and 8 cases of acute promyelocytic leukemia) and 3 cases of acute lymphoblastic leukemia. At the time of confirmed diagnosis, 6 patients were in first trimester, 6 cases in second trimester and 4 cases in late trimester. As for pregnancy outcome, 1 patient had natural birthing, 5 patients underwent cesarean operation, 9 patients underwent artificial abortion and 1 patient had spontaneous abortion. Chemotherapy was performed in 15 patients during pregnancy, 11 patients received chemotherapy for treatment of primary disease after pregnancy, 3 patients died during the treatment. During the follow-up of 13 cases, 8 patients survived and 5 patients lost follow-up.Conclusions:Early diagnosis of acute leukemia during pregnancy is very important. Bone marrow puncture should be performed timely to make clear diagnosis when blood routine result is abnormal during antenatal care. Multidisciplinary consultation should be initiated in time, and the best treatment plan should be worked out to guard against serious complications during pregnancy.

Objective:To retrospectively analyze the clinical outcomes of single unrelated cord blood transplantation (UCBT) in children with high risk and refractory acute myeloid leukemia (AML) .Methods:Between June 2008 and December 2018, a total of 160 consecutive pediatric patients with AML received single UCBT (excluding acute promyelocytic leukemia) . Myeloablative conditioning (MAC) regimen were applied.

Incidence of grades Ⅱ-Ⅳ and Ⅲ-Ⅳ acute GVHD and chronic GVHD were 37.3% (95%CI 29.3%-45.2%) , 27.3% (95% CI 20.0%-35.0%) and 22.4% (95% CI 15.5%-28.7%) , respectively. The transplant-related mortality (TRM) at 360 day was 13.1% (95% CI 8.4%-18.9%) . The 5-year cumulative incidence of relapse was 13.8% (95% CI 8.5%-20.3%) . The 5-year disease-free survival (DFS) and overall survival (OS) were 71.7% (95% CI 62.7%-77.8%) and 72.2% (95% CI 64.1%-78.7%) , respectively. The 5-year GVHD and relapse free survival (GRFS) was 56.1% (95% CI 46.1%-64.9%) . The 5-year cumulative recurrence rates of CR1, CR2, and NR groups were 5.3%, 19.9%, and 30.9% ( P=0.001) , and the 5-year OS rates were 79.9% (95% CI 70.3%-86.7%) , 71.1% (95% CI 50.4%-84.4%) and 52.9% (95% CI 33.0%-69.3%) ( χ2=7.552, P=0.020) , respectively. Conclusions:For pediatric patients with high risk and refractory AML, UCBT is a safe and effective treatment option, and it is favorable to improve the survival rate in CR1 stage.

Objective: To explore the clinical efficacy and safety of unrelated umbilical cord blood transplantation (UCBT) in the treatment of refractory and relapsed acute leukemia (AL) patients. Methods: The clinical data of 22 refractory and relapsed AL patients who were treated with UCBT as salvage therapy from November 2009 to May 2017 were retrospectively analyzed. All patients received a myeloablative conditioning regimen for prevention of graft-versus-host disease (GVHD) with cyclosporine A (CSA)/short course of mycophenolate mofetil (MMF). Results: ①Of 22 patients, 9 cases were male and 13 female. The median age was 23 (15-44) years and median weight of 52.5 (43-82) kg. All patients were transplanted with a median umbilical cord blood nucleated cells of 3.07 (1.71-5.30)×10⁷/kg (by weight), the median CD34⁺ cells was 1.60 (0.63-3.04)×10⁵/kg (by weight). ②The myeloid cumulative implantation rate was 95.5% (95%CI 45.2-99.7%) after transplantation of 42 d, with the median implantation time of 19 (13-27) d. The platelet cumulative implantation rate after transplantation of 120 d was 81.8% (95%CI 54.2-93.6%), the median implantation time of 42 (20-164) d. ③The incidence of Ⅱ-Ⅳ, Ⅲ-Ⅳ aGVHD and the 2 year cumulative incidence of cGVHD were 36.4%, 13.6% and 40.3% respectively. ④ The transplant related mortality (TRM) after transplantation of 180d was 22.7%, 2 year cumulative rate of relapse was 18.7% (95%CI 3.6-42.5%), 2 year disease-free survival rate (DFS) and overall survival rate (OS) were 53.7% and 58.1%, respectively. Conclusion The preliminary results show that the use of UCBT is safe and effective for refractory and relapsed AL patients who fail to respond to conventional chemotherapy.

Objective To analyze the epidemiologic and clinical features of post-engraftment blood stream infection (pePSI) after unrelated cord blood transplant (UCBT) in our hospital,and provide the basis for empiric antibacterial treatment.Methods 484 patients with hematological malignancies who received single-unit high intensity myeloablative UCBT in our hospital between April 2011 and November 2017 were enrolled.The incidence,etiology of BSI and associated mortality,drug resistance rate in the post-engraftment phase were investigated.Results Totally 25 episodes of BSI among 22 patients in the post-engraftment phase were documented,and the incidence of peBSI was 5 ％.Gram-negative organisms predominated over Gram positive,with Escherichia coli being the most frequent Gram-negative organism isolated (31.5％).Among Gram positive organisms,methicillin resistant Staphylococcus (MRS) was the most frequent species isolated (66％).Nearly 33％ of Escherichia coli isolates and 60％ Klebsiella pneumonia isolates were carbapenem-resistant.All Grampositive bacteria were sensitive to vaneomyein and linezolid.Among the 22 patients,14 patients were cured and survived (63％) eventually.Conclusion The most frequent causative agents of the peBSI after UCBT were Escherichia coli,Klebsiella pneumonia and MRS,etc.Combined antibacterial treatment including a carbapenem or beta lactamase inhibitor can be used for patients suffering fever in the post-engraftment phase as empiric antibacterial therapy.Vaneomyein and linezolid can be used as the first-line therapy for Gram-positive bacteria.

Objective To study the curative efficacy and safety of single-unit umbilical cord blood transplantation (sUCBT) for malignant hematologic diseases,which is provided by China's public cord blood bank.Methods We retrospectively analyzed 409 cases of malignant hematologic diseases who accepted myeloablative single-unit unrelated donor UCBT without ATG at our center between May 2008 and December 2016.A comparative analysis was made on the total nuclear cells (TNC) of the umbilical cord blood before freezing and after thawing,the cells of CD34+,the recovery rate of cells and the clinical effect of UCBT.Result 409 units of umbilical cord blood used in UCBT respectively came from eight China's public cord blood banks.The average TNC of 409 units of umbilical cord blood before freezing and after the tubular recovery were respectively 18.5 × 108 and 16.34 × 108 (p =0.000).The average recovery rate of the tubular recovery was 88.5％,and there was significant difference among cord blood banks (P =0.000).The average TNC of umbilical cord blood before freezing and transfusion were respectively 18.5 × 108 and 15.86 × 108 (p =0.000).The average recovery rate of umbilical cord blood transfusion was 85.9％,with the difference being significant among cord blood banks (P =0.000).The average number of CD34+ cells before freezing and after the tubular recovery was 11.18 × 106and 8.68 × 106 (p =0.000).The average recovery rate of CD34+ cells after the tubular recovery was 80.75 ％,with the difference being significant among the cord blood banks (P =0.000).At 42nd day after UCBT,the cumulative incidence of neutrophil engraftment was 95.4％,and the median time of the engraftment was 17 days (11-38 days).The cumulative incidence of platelet engraftment at 120th day was 84.6％,and the median time of the engraftment was 36 days (14-93 days).The cumulative incidence of erythrocyte engraftment at 60th day was 92％,and the median time of engraftment was 22 days (9d-60 days).After the umbilical cord blood provided by each bank was used in UCBT,it got the difference in cumulative incidence of engraftment.The P values for cumulative incidence of neutrophil,platelet and erythrocyte engraftment were respectively 0.004,0.01 and 0.000 2,with the differences being statistically significant.At 100th day after UCBT,the cumulative incidence of Ⅱ-Ⅳ and Ⅲ-Ⅳ degrees of acute graft-versus-host disease (aGVHD) was respectively 28.63％ and 15.7％.After umbilical cord blood provided by each bank was used in UCBT,it got the difference in cumulative incidence of aGVHD.There was no significant difference between Ⅱ-Ⅳ and Ⅲ-Ⅳ degrees (P =0.809 and 0.68 respectively).At 3rd year after UCBT,the cumulative incidence of relapse was 15.89％.After umbilical cord blood provided by each bank was used in UCBT,there was no significant difference in the cumulative incidence of relapse (P =0.898).At 3rd year after UCBT,the overall survival (OS) rate and disease free survival (DFS) rate were respectively 66.7％ and 59％.After umbilical cord blood provided by each bank was used in UCBT,it got the difference in OS and DFS.There was no significant difference in OS and DFS (P =0.566 and 0.703 respectively).At 3rd year after sUCBT,the rate of graft-versus-host diseases/relapse-free survival (GRFS) was 54.3％.After umbilical cord blood provided by each bank was used in UCBT,there was no significant difference in the rate of GRFS (P =0.449).Conclusion The umbilical cord blood provided by China's public cord blood bank was used in UCBT.It has a high safety and good efficacy in treating malignant hematologic diseases.But it needs to set up the standardized and normalized quality-control system of umbilical cord blood for China's public cord blood bank.

Objective: To compare the efficacy of unrelated cord blood transplantation (UCBT) and HLA-identical sibling peripheral blood stem cell transplantation (PBSCT) for the treatment of adult hematological malignancies. Methods: From April 2011 to December 2015, a total of 81 patients receiving single-unit UCBT and 57 patients receiving HLA-identical sibling PBSCT were enrolled in this study. All of the patients received myelablative conditioning. Cyclosporine combined with mycophenolate mofetil was adopted for GVHD prophylaxis. Results: The cumulative incidence of neutropil engraftment at day-42 was 95.0% and 100% in UCBT and sibling PBSCT groups, respectively (P=0.863) . Platelet engraftment at day 100 was 87.3% (95%CI 76.8%-93.1%) in UCBT group, which was significantly lower than that of sibling PBSCT group[98.2% (95%CI 87.3%-99.7%) ] (P=0.005) . There were no significant differences in terms of Ⅱ-Ⅳ acute GVHD or Ⅲ-Ⅳ acute GVHD in two groups (P=0.142, 0.521) . The 3-year chronic GVHD and extensive chronic GVHD were 14.9% (95%CI 5.2%-23.5%) and 11.2% (95%CI 2.9%-18.7%) , respectively in UCBT group, which was significantly lower than that of sibling PBSCT group[35.2% (95%CI 19.4%-47.8%) , 31.4% (95%CI 16.2%-43.9%) ] (P=0.008, 0.009) . The 3-year transplant-related mortality (TRM) was similar between two groups (30.1% vs 23.2%, P=0.464) . The relapse rate at 3-year in UCBT group[12.9% (95%CI 6.6%-21.5%) ]was significantly lower than that in sibling PBSCT group[24.3% (95%CI 13.5%-36.8%) ] (P=0.039) . There were no significant differences in terms of overall survival (OS) and disease-free survival (DFS) between two groups (58.6% vs 54.8%, P=0.634; 57.0% vs 52.4%, P=0.563) . But GVHD-free and relapse-free survival (GRFS) in UCBT group [55.7% (95%CI 44.1%-65.8%) ]was significantly higher than that of sibling PBSCT group[42.9% (95%CI 29.8%-55.3%) ] (P=0.047) . Conclusions For adult hematological malignancies, the incidences of acute GVHD and TRM were similar between UCBT and sibling PBSCT recipients, and the incidences of chronic GVHD and relapse were lower in UCBT recipients. UCBT recipients had higher GRFS rate although OS and DFS were similar between two groups, which may reflect the real recovery and better quality of life following UCBT.

Objective To investigate the effects of the erythropoietin (EPO) on ischemia reperfusion injury (IRI) in rats with nephron-sparing surgery (NSS). Methods Fifty-four Sprague Dawley rats were divided into 3 groups randomly after right kidney nephrectomy: Sham group, NSS group (PBS+NSS) and EPO group (EPO+NSS). During NSS, renal artery was clamped for 40 min to induce IRI. Sham group just adopted exposure renal artery without vascular clamped. Rats in NSS group were injected intraperitoneally with PBS for 3 days before NSS. Rats in EPO group were injected intraperitoneally with EPO for 3 days before NSS. After 12 h, 24 h, 72 h, blood sample and renal tissues were collected. The serum creatinine (Scr) and urea nitrogen (BUN) were evaluated. The pathology injury was evaluated by HE staining. The CD24/CD133 double-positived renal progenitor cells (RPCs) were tested by flow cytometry. The CD133 and PCNA protein were quantified by immunohistochemical staining. The expressions of Wnt7b and β-catenin protein were detected by Western blotting. Results Rats in NSS group had more elevated Scr, BUN and pathology injury scores 12 h, 24 h and 72 h after operation than those in Sham group (all P<0.05). Compared with those in the NSS group, the Scr and BUN in the EPO group were significantly lower 24 h after the surgery (all P<0.05), and the pathology injury score also decreased (P<0.05). The proportion of RPCs, expressions of CD133 and PCNA, and expressions of Wnt7b and β-catenin protein were significantly higher after 24 h of the surgery in NSS group than those in the Sham group (all P<0.05). While compared with those in the NSS group, the proportion of RPCs and expressions of CD133, PCNA, Wnt7b and β-catenin increased at the EPO group (all P<0.05). Conclusions EPO can reduce the IRI after NSS, and its mechanism may be related to the mobilization of the RPCs by the Wnt7b/β-catenin signal pathway.

OBJECTIVETo retrospectively study the impacts of ABO incompatibility on early outcome after single unit unrelated cord blood transplantation（UCBT）, such as cumulative incidence of engraftment, incidence of acute graft- versus- host disease （aGVHD） and 180- day transplant- related mortality（TRM）.

METHODS208 patients underwent single unit UCBT from April 2008 to October 2014 were analyzed, included 99 ABO- identical, 60 minor, 38 major and 11 bidirectional ABO- incompatible recipients. All the patients received intensified myeloablative conditioning, and a combination of cyclosporine A and mycophenolate mofetil was given for GVHD prophylaxis.

RESULTSCumulative incidences of neutrophil engraftment, platelet recovery, erythroid lineage reconstitution, Ⅱ-Ⅳ aGVHD, Ⅲ-Ⅳ aGVHD and 180- day TRM showed no significant difference among the patients receiving ABOidentical, minor, major, and bidirectional UCBT（all P>0.05, respectively）. What's more, none of the patients developed pure red- cell aplasia（PRCA）after UCBT. Group A donor and a group O recipient patients didn't appeared to influence the clinical results when compared with others（all P>0.05, respectively）.

CONCLUSIONPatients receive ABO- incompatible UCBT may not develop PRCA. The presence of ABO- incompatibility did not influence the hematopoietic reconstitution, the incidence of aGVHD and 180-day TRM in this cohort. There is not support for the need to regard ABO-compatibility as an UCB-graft selection criterion.
