OBJECTIVETo observe the effect of natural type ginsenoside Rg2 (Rg2) and its stereoisomers [20 (R)-Rg2 and 20 (S)-Rg2] at different concentrations on oxygen-glucose deprivation/ reperfusion (OGD/R) induced cortical neuronal injury model in vitro, and to explore the mechanism, and compare their differences of action.
METHODSCortical neurons after 7-day culture were randomly divided into 5 groups, i.e., the control group, the model group, the Rg2 group, 20 (R) -Rg2 group, and 20 (S) - Rg2 group. Cortical neurons in the Rg2 group, 20 (R)-Rg2 group, and 20(S)-Rg2 group were pretreated with 20, 40, and 80 μmol/L Rg2, 20 (R) -Rg2, and 20 (S) -Rg2 for 24 h to prepare OGD/R model. The cell survival rate, the activity of Caspase-3, the intracellular Ca2+ concentration, contents of superoxide dismutase (SOD) and malondialdehyde (MDA) were detected 24 h later.
RESULTSCompared with the control group, cell survival rates and activities of SOD obviously decreased, the activity of Caspase-3, Ca2+ fluorescent optical gray value, and contents of MDA significantly increased with statistical difference (P < 0.05). Compared with the model group, cell survival rates and activities of SOD obviously increased, the activity of Caspase-3, Ca2+ fluorescent optical gray value, and contents of MDA significantly decreased in 20 μmol/L Rg2 group, 40 μmol/L 20 (R) -Rg2 group, and 80 μmol/L 20 (S) -Rg2 group (P < 0.05). Compared with 20(S)-Rg2 group, cell survival rates increased and contents of MDA significantly decreased in 20, 40, and 80 μmol/L Rg2 and 20 (R)-Rg2 groups (P < 0.05). The activity of Caspase-3 decreased and contents of SOD increased in 80 μmol/L 20 (R)-Rg2 group, and 40, 80 μmol/L Rg2 groups (P < 0.05). Ca2+ fluorescent optical gray value decreased in 40, 80 μmol/L Rg2 and 20 (R)-Rg2 groups (P < 0.05). Compared with 20 (R)-Rg2 group, Ca2+ fluorescent optical gray value decreased in 80 μmol/L Rg2 group (P < 0.05); contents of SOD increased in 40 and 80 μmol/L Rg2 groups (P < 0.05); contents of MDA decreased in 20, 40, and 80 μmol/L Rg2 groups (P < 0.05).
CONCLUSIONSRg2 and its stereoisomers could improve cell vitality of cortical neurons against OGD/R induced injury. This might be related to improving anti-apoptotic capacities and antioxidant abilities, and reducing Ca2+ inflow. Besides, the neuroprotective effect of 20 (R) -Rg2 was better than that of 20 (S) -Rg2, but inferior to that of Rg2.

Objective To assess the feasibility of using PET molecular imaging to evaluate the therapeutic effects of traditional Chinese medicine FuZhiSan (FZS) on the model of aging Alzheimer's disease (AD) rats. Methods Twenty aged AD rats (Sparague-Dawley rats,male) were randomly divided into FZS treated group (n = 10) and control group (n = 10). Another 10 healthy adult rats were as blank controls. Morris water maze record system was used for cognitive function assessment. Before and after FZS treatment 18 F-fluorodeoxyglucose (FDG) and 11 C-2- [4'-(methylamino) phenyl] benzothiazol-6-ol ( PIB )PET imaging was undertaken. After post-treatment imaging procedures the brain tissues of all animals were taken for histochemical study,such as staining with HE,congo red,amyloid β (Aβ) immunofluorescence,5-bromo-2-deoxyuridine (BrdU) immunofluorescence and NeuN immunofluorescence. Paired t-test was performed with SPSS 13.0 software for the data analysis. Results The cognitive dysfunction of aging AD rats was improved after FZS treatment. The escape latency in FZS treated group was significantly shorter than that of control group ((32.5 ±10.8) s vs (102.6±8.8) s,t =15.7987,P=0. 0001). Diffuse neuronal loss and Aβ deposition were detected in the hippocampus and cortex in the aged AD rats. The imaging data showed that brain glucose metabolism was amended in FZS treated group while the abatement of amyloid deposition was not significant. Immunofluorescence results indicated that the neuronal proliferation was more remarkable in FZS treated group. Conclusions It may be feasible to use PET imaging as a method to evaluate the therapeutic effect in AD rats. FZS may ameliorate memory dysfunction of aged AD rats. Its mechanism may be partly contributed to the enhancement of the neuronal proliferation and survival.

Objectives To evaluate the efficacy of rituximab combined with chemotherapy in the treatment of diffuse large B-cell lymphoma (DLBCL) and the relationship of clinical prognosis with the International Prognostic Index (IPI) by the using rituximab in autologous peripheral stem cell transplantation (APBSCT) for the patients of DLBCL. Methods 21 patients with DLBCL, 11 patients of them were at IPI low risk, and 3 patients were IPI at low intermediate risk, 3 patients were at IPI high intermediate risk, 4patients IPI high risk. Rituximab combined with CHOP regimen (cyclophosphamide, adriamycin, vincfistine and prednisone) was given for 4~8 courses. 5 patients received APBSCT. The mobilizing regimen was rituximab combined with cyclophosphamide(CTX) and etoposide(VP16). The conditioning regimen were CBV(CTX combined with VP16 and carmustine). Results In 21 patients, the complete response rate was 61.9 %,with overall response rate 90.5 %. 2-year progression free survival was (69.74±10.43)%. 2-year overall survival was (84.44:1:8.35) %. The complete response rate was 92.9 % and overall response rate was 100 % in the patients IPI≤2. The overall response rate was 71.4 % in the patients with IPI≥3. The complete response rate was higher in the patients with IPI≤ 2 (P<0.01). The amount of mononuclear cells (M NC) in harvest were 7.34 (4.6~8.53)×108/kg. The CD+34 cells in harvest were 8.82 (2.1~10.34)×1O6/kg. The mean time of neutrephil recovering to 0.5×109/L after APBSCT was +9 day. The mean time of platelet recovering to 20×109/L after APBSCT was +12 day. The major adverse reaction were infusion related response (14.3 %) and hematological toxieities. Conclusion The efficacy of rituximab combined with chemotherapy in the treatment of DLBCL is effective, The complete response rate was higher in the patients with IPI≤2 than in the patients with IPI≥3.Using rituximab in mobilizing regimen, all patients had harvested enough CD+34 cells. Rituximab given at +1day did not affect the hematopoiesis reconstruction.

Objective:To evaluate the clinical efficiency and prognostic factors of autologous peripheral blood stem cell trans-plantation (APBSCT) in 30 cases of multiple myeloma (MM). Methods:Two of the 30 patients received the second treatment of APB-SCT because of relapse after the first treatment. Thus, a total of 32 case-times of APBSCT were studied. Combination chemotherapy was inducted regularly before APBSCT (11 patients used bortezomib as an induction drug), and chemotherapy combined with the G-CSF regimen was used to mobilize peripheral blood stem cells. Preconditioning was based on melphalan. Results:Mononuclear cells in harvest were 6.41 × 108/kg, and CD34+cells in harvest were 4.75 × 106/kg. The median times of neutrophil and platelet engraftment were 9.5 and 11 d, respectively. The complete remission (CR) and very good partial remission (VGPR) rates were 37.5%and 34.4%af-ter APBSCT, respectively. The median overall survival (OS) was 67.27 months in all patients, and the median progression-free survival (PFS) was 29.77 months. The median PFS rates were 29 and 20 months in the patients who achieved CR and PR, respectively, and the median PFS was not observed in the patients who achieved VGPR. Statistical differences in PFS were detected between the CR+VGPR and PR groups (P=0.025). The CR rates were 63.6%and 23.8%in the bortezomib (bortezomib-based chemotherapy) and non-bortezo-mib groups (P=0.034), respectively. The median OS and PFS were not obtained in the bortezomib group, whereas the median PFS was 22 months in the non-bortezomib group (P=0.045). Conclusion: MM patients treated with bortezomib-based chemotherapy followed by APBSCT had prolonged PFS. APBSCT can improve the response and survival of MM patients.

OBJECTIVETo evaluate causes and clinical management of postoperative pain after total knee arthroplasty (TKA).
METHODSFrom January 2004 to June 2009, 41 patients (44 knees) with knee pain post TKA were treated. There were 9 male and 32 female patients aging from 51 to 84 years with a mean of 63.5 years. The diagnosis followed to Brown diagnostic system. One case of extraarticular pain was complex regional pain syndrome type 1 (CRPS-1) and underwent conservative treatment, the remaining 5 cases were treated by surgery. Three cases of joint instability, 1 case of patellar baja, 2 cases of soft tissue impingement caused by overhang of the prosthesis, 1 case of popliteal tendon impact underwent conservative treatment, the other 27 cases underwent surgical intervention. The patients were followed up and the Knee Society Score (KSS) knee score, pain visual analog scale (VAS) score were recorded.
RESULTSForty-one cases were followed up for 1 to 6 years. At the last time of follow-up, the 5 cases received surgical treatment to extra-articular pain showed VAS score as 2.5 ± 0.2, KSS clinical and functional score as 92.8 ± 2.6 and 89.0 ± 3.4. There was significantly difference compared with preoperative (P < 0.05). One case of CRPS-1 performed conservative treatment, the therapy was effective. In the infected 12 cases of intra-articular pain, 1 case received amputation, 3 cases received antibiotic bone cement insert, 8 cases received two stage revision. All infections were cured, and VAS score was 3.8 ± 0.2, KSS clinical score was 88.3 ± 4.6, function score was 85.0 ± 4.6 postoperatively, with significantly difference compared with preoperative (P < 0.05). In the 8 cases received conservative treatment in non-infected group, at the last time of follow-up, VAS score was 4.5 ± 0.4, KSS clinical and functional score was 85.4 ± 4.2 and 84.2 ± 2.3, with significantly difference compared with preoperative (P < 0.05). Fifteen cases underwent surgical treatment, at the last time of follow-up, VAS score was 3.4 ± 0.1, KSS clinical and functional score was 86.6 ± 5.4 and 87.1 ± 2.4, with significantly difference compared with preoperative (P < 0.05).
CONCLUSIONSPatients with knee pain post TKA need systematic assessment to identify the causes. Appropriate treatment due to the positive diagnosis generally lead to satisfactory results, surgical intervention with indefinite causes is strictly prohibited.

OBJECTIVETo isolate, identify and culture human spermatogonial stem cells (SSC) and then obtain purified and enriched human SSCs for research and application.
METHODSWe detected the expression of CD90 in the human testis using the immunofluorescence technique and isolated human testicular spermatogenic cells by two-step enzymatic digestion, followed by differential plating and magnetic-activated cell sorting (MACS) with CD90 as an SSC marker. Then we identified the isolated CD90-positive spermatogenic cells by RT-PCR and immunocytochemistry, and meanwhile cocultured them with Sertoli cells in SG medium in vitro.
RESULTSThe isolated CD90-positive cells showed a relatively homogeneous characteristic in size and morphology and expressed the genes specific for human SSCs, with high expressions (90.5%) of GFRA1, GPR125, and UCHL1. After coculture with Sertoli cells in the SG medium for 2 weeks, the isolated CD90-positive cells maintained a good activity.
CONCLUSIONCD90 can be regarded as a speci- fic marker for human SSCs and used to obtain highly enriched human SSCs by differential plating and MACS. Furthermore, the isolated human SSCs can be cultured in SG medium in vitro.
