Objective To evaluate the clinical efficacy and adverse effects of CAG regimen in treatment of primary, refractory and relapsed acute myeloid leukemia (AML) and high risk myelodysplastic syndrome (MDS), and analyse the factors influencing long-term survival. Methods Sixty-one patients with AML ( primary, n = 27; refractory, n = 18; relapsed, n = 16) and 9 patients with MDS were treated with CAG regimen. Examinations on liver and renal function, electrocardiogram and bone marrow cytology were performed before and after treatment, and adverse effects of CAG were observed. Short-term efficacy was evaluated based on clinical manifestation, peripheral blood and bone marrow cytologic examinations. Patients were followed up, overall survival ( OS) and disease free survival ( DFS) were analysed, and long-term efficacy of CAG regimen was evaluated. The factors influencing long-term survival were analysed by Log-rank test of survival curve. Results After a course of treatment by CAG regimen, the total effective rate was 71% , and 34 patients (49%) experienced complete remission. The median time of follow up was 45 months, the median OS was 28 months, and the median DFS was 23 months. Age, level of lactate dehydrogenase (LDH), remission condition after a course of treatment by CAG regimen and adoption of HD-Ara-C regimen as consolidation treatment were influencing factors for OS and DFS. The dominant clinical adverse effects were bone marrow depression, with 13 d as the median duration of agranulocytosis ( neutrophil <0.5 ×10~9/L) and 9 d as the median duration of thrombocytopenia (platelet <20 ×10~9/L). Conclusion CAG regimen may lead to favourable therapeutic effects in treatment of primary, refractory and relapsed AML and high risk MDS, and may yield less adverse effects and better long-term therapeutic effects. Age, level of LDH, remission condition after a course of treatment and adoption of HD-Ara-C regimen as consolidation treatment are dominant influencing factors for survival.

OBJECTIVETo investigate the impact of in utero exposure to di-n-butyl phthalate (DBP) on the apoptosis of testicular cells in the pubertal male rat offspring.

METHODSTen pregnant SD rats were randomly divided into a control and an experimental group to be treated intragastrically with olive oil (1 ml per day) and DBP (500 mg per kg of body weight per day) respectively between gestation days 12 and 19. At the pubertal age (postnatal day 45, PND 45), the testes of the male rat offspring were removed for observation of the cell structure under the transmission electron microscope and the development of different spermatogenetic cells by HE staining. The apoptosis of testicular cells was detected by the TUNEL method, the expressions of the apoptosis-regulating proteins Bcl-2, Bcl-XL, Bax and p53 were determined by immunohistochemistry and Western blot, and the data obtained were compared between the two groups by t-test.

RESULTSTransmission electron microscopy revealed increased apoptosis and vacuolization of testicular cells in the PND-45 rat offspring, HE staining showed markedly decreased numbers of different spermatogenetic cells, TUNEL manifested significantly increased apoptosis of testicular cells in the experimental group as compared with the control (12.00 ± 5. 22 vs 3.17 ± 1.47, P < 0.01), and immunohistochemistry and Western blot exhibited remarkably higher expressions of Bax and p53 in the former than in the latter group (P < 0.05).

CONCLUSIONIn utero exposure to DBP can increase the apoptosis of germ cells and Sertoli cells, induce the vacuolization of testicular cells, and significantly elevate the expressions of the apoptosis-promoting proteins Bax and p53 in the pubertal male rat offspring.

Objective To study multiple cytokine mRNA expressions of bone marrow stromal cells in patients with multiple myeloma(MM),as well as to explore the role of these cytokines in the occurrence and development of MM.Methods Semi-quantitiative RT-PCR was used to detect the mRNA expressions of IL- 1?,IL-6,SCF,TPO.Results The mRNA expression levels of IL-1? and IL-6 were higher than that of nor- mal controls and other hematological malignancies(P

Objective To evaluate the safety, efficiency and feasibility of HLA-identical sibling using culture-expanded mesenchymal stem cells and hematopoietic stem cells in treatment for myelodysplastic syndrome (MDS). Also to investigate for valid preventive measures to avoid the infection of HBV originated from donor. Methods A 46-years-old male patient with myelodysplastic syndrome-refractory anemia (MDSRA) got a cotransplantation of culture-expanded mensenchymal stem cells (MSC) and hematopoietic stem cells (HSCs) from HLA-identical sibling donor (his sister) who was infected by hepatitis B virus (HBV). Some measures were applicated in order to avoid the recipient from getting a HBV infection. The antiviral therapy to the donor was began early at the time 1 month before transplant, and HBV vaccine inoculation was used 2 month before transplant. High titer of anti-hepatis B immunoglobulin was used 1 week before transplant and 1 month after transplant the use of prophylactic anti-hepatis B drug treatment was begun. A non-myeloablative preparative regimen included fludarabine monophosphate (Flu, 120 mg/m2), cyclophosphamide (Cy, 1200 mg/m2)and antithymocyte globulin (ATG, 15 mg/kg) was given to him before culture-expanded mesenchymal stem cell and allogeneic peripheral blood stem cell from his HLA-matched sister. Results The regimen was well tolerated, and hemopoiesis was reconstituted on day 10 after transplant, idiochromosome detected by fluorescent in situ hybridization on day 30 showed XY 47/300 and on day 90 it was 7/300. No evidence of HBV infection was detected on day 60 after transplant. Conclusion The clinical course of this patient indicate that HLA-identical sibling culture-expanded mesenchymal stem cell transplantation combined with non-myeloablative stem cell transplantation can be an effective and safe approach in treatment of MDS.

Objective To study the efficacy and feasibility of the one-stage and two classification method to treat concomitant gallbladder stones and common bile duct stones.Methods 56 consecutive patients with concomitant gallbladder stones and common bile duct stones in Central Hospital of Huzhou were treated with the one-stage and two classification method from January 2013 to January 2017.According to the size and quantity,common bile duct stones were divided into difficult stones and non difficult stones.In plan A (n =35),endoscopic stone clearance and laparoscopic cholecystectomy were undertaken in a single operation to treat non difficult stones,In plan B (n =21),laparoscopic cholecystectomy and CBD exploration without T-tube insertion were undertaken in a single operation to treat difficult stones.The operation success rate,postoperative complications,hospitalization stay and follow-up outcomes were analyzed.Results Fifty-six patients were enrolled in the study.Fifty-one patients were treated by the one-stage and two classification method.Among them,thirty-two patients followed treatment plan A.Three patients were convened to plan B because of failure of bile duet intubation.Nineteen patients were treated by plan B.One patient was converted to laparotomy,and another underwent T-tube drainage.The incidence of complication was 7.1％.Post-ERCP pancreatitis happened in one patient.Post ERCP bleeding happened in another patient (1.6％).Bile leakage occurred in one patient,and incision infection occurred in one patient.There were no deaths.During a follow-up of 6-24 months,no stone recurrence and bile duct stenosis were observed.Conclusion The one-stage and two classification method was an effective and feasible alternative to manage concomitant gallbladder stones and common bile duct stones.

Objective To investigate the early clinical outcome of peripheral cutting balloon(PCB) in the management of peripheral vessel stenosis.Methods Thirteen patients with peripheral limb vessel stenosis, in which 4 stenoses in hemodialysis access and 9 at lower limb arteries,underwent angioplasty by PCB.For multiple stenosis in the same vessel,the distal one should be expanded firstly.The balloon pressure was controlled in the range of 8 atm to 10 atm(1 atm=10.108 kPa).All the patient were given continuous anticoagulant therapy after the procedure.Results All the procedure were carried out successfully on the 13 patients,and no serious complications occured.The symptoms did not recur in all patients after the procedure.The 5 months' follow-up angiography proved that no restenosis occurred in one patient with previous stenosis at the hemodialysis access.Conclusion The angioplasty with PCB was a safe and reliable procedure in management of the peripheral limb vessel stenosis.The early outcome is satisfying.

Objective To investigate the effects of partial body weight supported treadmill training (BW- STT) on post-stroke depression (PSD) and on patients' quality of life.Methods Sixty patients with PSD were re- cruited and divided into a training group (n=30,male 17,female 13) and a control group (n=30,male 16,fe- male 14).All patients were treated with routine internal medication and rehabilitation.The patients of the training group also received BWSTT in addition to their routine treatment.All patients' neurological impairment was evaluated using the Modified Edinburgh-Scandinavian Stroke Scale (MESSS).The Hamilton depression scale (HAMD) was used for evaluating the degree of depression.The Fugl-Meyer scale and the Barthel index were used to assess ambula- tion and balance,and facility in the activities of daily living.All patients were assessed before and after the treat- ment.Results After four weeks of treatment,depression in the training group had improved significantly more than in the control group.Conclusion BWSTT intervention is very important for patients with PSD:it can reduce the degree of depression and improve the quality of life.

Objective To analysis long-term effects and safety of arsenic trioxide (ATO)-based induction and maintenance therapy in newly diagnosed acute promyelocytic leukemia (APL). Methods Retrospective analysis induction remission and post-remission treatment of 62 newly diagnosed APL patients was performed. These cases were followed up for 5 and 7 years. Results The complete remission (CR) rate was similar in ATO/all-trans retinoic acid (ATRA) induction group and ATRA/chemotherapy induction group.However, the former group has the shorter time to CR. The negative rate of PML-RARα fusion gene after induction without ATO was less than that of ATO group (86.2 % vs 56.3 %, P ＜0.05). After CR, the 5-year overall survival (OS) between ATO-base rotation maintenance group and chemotherapy-base rotation maintenance group showed that the former was (94.4±5.4) %, the latter is (45.5±10.2) %; 7-year OS was (52.5±23.7) % and (27.3±9.3) %; 5-year disease free survivals (DFS) was (94.7±5,5) % and (41.3±10.1) %; 7-year DFS was (52.6±23.7) % and (27.5±9.4) %. There was significant different in 5-year or 7-year OS and DFS between two groups (P ＜0.05). The relapse rates of the two groups in post-remission treatment were 14.7 % and 37.0 % (P ＜0.05). Conclusion ATO combined ATRA induction therapy increased the negative rate of PML-RARα fusion gene. ATO-base rotation maintenance improved long-term outcome and decreased the rate of relapse. Furthermore, ATO appeared to be generally safe and well tolerated.
