Urinary brain-derived neurotrophic factor (BDNF),an ubiquitous neurotrophin,was found to rise in patients with benign prostatic hyperplasia (BPH).We hypothesized that the urinary level of BDNF could be a potential biomarker for lower urinary tract symptoms (LUTS) in patients with BPH.Totally,76 patients with BPH-caused LUTS and 32 male control subjects without BPH were enrolled.International Prostate Symptom Score (IPSS) was applied to assess the symptom severity of LUTS.Urodynamic tests were performed for the diagnosis of underlying detrusor overactivity (DO) in the patients with BPH.Urine samples were collected from all subjects.Urinary BDNF levels were measured using enzyme-linked immunosorbent assays and normalized by urinary creatinine (Cr) levels.Seventy-six BPH patients were divided into moderate LUTS group (n=51,7＜IPSS ≤ 20) and severe LUTS group (n=25,IPSS＞20) according to the IPSS.Of the 76 BPH patients,DO was present in 34 (44.7％)according to the urodynamic test.The urinary BDNF/Cr levels were significantly higher in BPH patients with moderate LUTS (8.29±3.635,P＜0.0001) and severe LUTS (11.8±6.44,P＜0.0001) than normal controls (1.71±0.555).Patients with severe LUTS tended to have higher urinary BDNF/Cr levels than patients with moderate LUTS (11.8±6.44 vs.8.29±3.635,P=0.000).The conditions of BPH with LUTS correlated with elevated urinary BDNF levels,and urinary BDNF levels were even higher in BPH-DO patients.The results of this study have provided evidence to suggest that urinary BDNF level test could evaluate the severity of LUTS in BPH patients,and BDNF level can be used as a biornarker for the diagnosis of DO in BPH patients.

BACKGROUND:The incidence rate of peripheral T cel lymphoma is high in Asia, and peripheral T cel lymphoma is aggressive with generaly poor prognosis. However, there is no standard treatment strategy. OBJECTIVE:To retrospectively analyze the therapeutic effect of autologous hematopoietic stem cel transplantation on peripheral T cel lymphoma as wel as relevant toxic and side effects. METHODS:A retrospective review was conducted in 35 patients with peripheral T cel lymphoma who underwent autologous hematopoietic stem cel transplantation from March 2003 to April 2014, including 22 cases of extranodal NK/T-cel lymphoma (nasal type), 1 case of angioimmunoblastic T-cel lymphoma, 8 cases of peripheral T cel lymphoma (non-specific), 3 cases of ALK-positive anaplastic large cel lymphoma, and 1 case of ALK-negative anaplastic large cel lymphoma. Al of 35 patients were classified pathologicaly according to WHO pathological type in 2001 and 2008, and received the high-dose chemotherapy with vincristine, cytarabine, etoposide, mitoxantrone, semustine, cyclophosphamide, and total body irradiation. RESULTS AND CONCLUSION: After a median folow-up of 54 (9-120) months, the probabilities of overal survival and disease-free survival after transplantation were 80% (n=28) and 71% (n=25), respectively. Eight cases (23%) relapsed after transplantation, seven of which died. It was safe with mild and moderate transplantation related side-effects on opportunistic infections, oral cavity mucosa and bladder responses and so on, and there were no severe, life-threatening late complications. Autologous hematopoietic stem cel transplantation may be an effective and safe treatment for peripheral T cel lymphoma, and there is a better benefit in peripheral T cel lymphoma patients with first complete remission.

OBJECTIVETo investigate development of a cell extraction process for preparing human meniscus acellular matrix, and morphology and biomechanical properties.

METHODSHuman meniscus were subjected to modified eight-step detergent, then, the specimens were assessed by staining with haematoxylin-eosin, toluidine blue, sirius red, saffron O, alcain blue and hoechst-33258, et al. The ultrastructure of the specimens was observed with scanning electron microscope. Transient recovery rate of deformation, maximal recovery rate of deformation and maximal compressive strength were tested to determine the biomechanical properties of the scaffold.

RESULTSEvery stain confirmed that the celluar constituents of the specimens were removed. The specimens stained positively by staining with sirius red. Lacuna were found irregularly not only on the surface of the meniscus,but also in the meniscus with scanning electron microscope. Pores in the specinmens were large, the diameter of pores was 80 to 760 microm, porosity was over 67%. The transient recovery rate of deformation was (89.62 +/- 1.04)%, the maximal recovery rate of deformation was 100% and the maximal compressive strength was (3.04 +/- 0.13)N, when the specimens were compressed 30%.

CONCLUSIONThe modified eight-step detergent can remove the immunogenic cell components from human meniscus, in addition, 3D extracellular matrix can be retained. The scaffold has good biomechanical properties. This scaffold stands a good chance to be an implant for future tissue engineering of the human meniscus.

Objective To investigate the curative effect of allogeneic hematopoietic stem cell transplantation (allo-HSCT) and the method of the pretreatment choice on myelodysplastic syndrome (MDS).Methods 13 cases who were undergoing allo-HSCT including 10 HLA-matched, 2 HLA partially matched,and one umbilical cord blood transplanted patients were enrolled in this study. The infusion number of MNC and CD+34 cells is 6.92 (2.65-21.33)×108/kg and 4.47 (1.49-10.22) ×106/kg, respectively. Of the 13 cases,5 adopted TBI, fludarabine(Flud), and cyclophosphamide(Cy) pretreatment, 3 chose BU/Cy pretreatment, and 3 chose TBI and Cy pretreatment, 2 chose Ara-C+BU+Cy+VM26 pretreatment. In order to prevent GVHD, 2cases of HLA partially matched were treated with ATG, cyclosporin A (CsA), MTX and MMF aftertransplantation, while the others were treated with CsA and MTX only. Results 9 out of 13 cases achieved hematopoietic reconstruction completely. 4 died of complications. Conclusion The allogeneic hematopoietic stem cell transplantation is an efficient regimen to cure MDS. The pretreatment should adopt the individuation.

The clinical characteristics of patients who presented in poor clinical grade due to ruptured middle cerebral artery aneurysms (MCAAs) associated with large sylvian hematomas (SylH) were analyzed and an ingenious designed prophylactic hinged craniectomy was introduced. Twenty-eight patients were graded into Hunt-Hess grades IV-V and emergency standard micro-neurosurgeries (aneurysm clipping, hematoma evacuation and prophylactic hinged craniectomy) were performed, and their clinical data were retrospectively analyzed. 46.43% of the patients reached encouraged favorable outcomes on discharge. The favorable outcome group and the poor outcome group significantly differed in terms of patients' anisocoria, Hunt-Hess grade before surgery, extent of the midline shift and time to the surgery after bleeding (P<0.05). There were no significant differences in age, sex, volume and location of the hematoma, size of aneurysm between the favorable and poor groups (P>0.05). However, ingenious designed prophylactic hinged craniectomy efficiently reduced the patients' intracranial pressure (ICP) after surgery. It was suggested that preoperative conditions such as Hunt-Hess grading, extent of the midline shift and the occurrence of cerebral hernia affect the prognosis of patients, but time to the surgery after bleeding and prophylactic hinged craniectomy are of significant importance for optimizing the prognosis of MCAA patients presenting with large SylH.

BACKGROUND:Studies have shown that paeoniflorin functions as replenishing blood and treatment of autoimmune diseases, and bone marrow mesenchymal stem cels also play an important role in the body’s blood and immune function. However, paeoniflorin effects on bone marrow mesenchymal stem cel proliferation and cytokine secretion and expression are rarely reported. OBJECTIVE:To investigate the effect of paeoniflorin on proliferation of bone marrow mesenchymal stem cels and the expression of interleukin-6. METHODS:Human bone marrow mesenchymal stem cels were separated and culturedin vitro by density gradient centrifugation combined with attachment method. The biological characteristics of bone marrow mesenchymal stem cels were identified by flow cytometry and osteogenic/adipogenic induction. The proliferation of bone marrow mesenchymal stem cels under different concentrations of paeoniflorin was detected by MTT method. The mRNA expression and secretion of interleukin-6 in the supernatant of bone marrow mesenchymal stem cels were detected by RT-PCR and ELISA, respectively. RESULTS AND CONCLUSION: Bone marrow mesenchymal stem cels were isolated successfuly and had osteogenic and adipogenic differentiation potential. Compared with the controlgroup, 2 μmol/L and 10 μmol/L paeoniflorin significantly promoted the proliferation of bone marrow mesenchymal stem cels. 10 μmol/L paeoniflorin could significantly decrease the proportion of bone marrow mesenchymal stem cels in G0/G1 phase and increase this proportion in S phase. Compared with the control group, the experimental group could significantly increase the secretion and mRNA expression of interleukin-6 (P < 0.01). It is concluded that paeoniflorin at certain concentrations can obviously promote the proliferation of bone marrow mesenchymal stem cels, and increase the expression and secretion of interleukin-6.
