Objective To investigate the efficacy of HLA-matched ABO-incompatible sibling al- logeneic peripheral blood stern cell transplantation(allo-PBSCT)in treatment of hematologic malig- nancies.Methods Between June 2001 and September 2005,68 patients with hematologic malignancies received allo-PBSCT from HLA-identical sibling donors.Among them,38 were ABO-compatible (ABO-compatible group),30 ABO-incompatible(ABO-incompatible group).Conditioning regimen of all patients:BU/CY used as conditioning regimen in AML,MDS and CML patients;TBI/CY used in ALL and NHL patients.TBI/CY/Melphan used in MM patients.GVHD prophylaxis:A combination of cyclosporine(CsA)and mycophenolate mofetil(MMF)and methotrexate(MTX)was administered for GVHD prophylaxis.Results (1)Sixty-seven patients were all engrafted,and only one patient was graft failure.The median time(range)to neutrophils≥0.5?10~9/L and platelets≥20?10~9/L was +12(+9～+15)and+21(+15～+40)days post-transplant respectively.The time to neutrophil and platelet engraftment had no significant difference between ABO-incompatible group and ABO-com- patible group(P＞0.05);(2)Thirty patients with ABO-incompatible allo-PBSCT had no evidence of hemolysis.In ABO-incompatible group,the onset of erythropoiesis after allo-PBSCT was delayed. Three of 7 patients with blood group“O”receiving a group“A”developed pure red cell aplasia (PRCA).The blood type of 30 patients would transfer to the type of donors in 60 days(24～153 days)after transplantation.(3)Following up to 30th,Sep.2005,the incidence of aGVHD was high- er in ABO-incompatible group(20.0%)than that in ABO-compatible group(2.6%,P=0.019). The incidence of cGVHD,VOD,HC,CMV infection,disease relapsed rates and mortality had no sig- nificant difference between ABO-incompatible and ABO-compatible recipients(P＞0.05).(4)Kaplan- Meier survival analysis revealed the rates of survival had no significant difference between ABO-incom- patible and ABO-compatible recipients(P＞0.05).Conclusions ABO-incompatible allo-PBSCT is fairly safe if there is indication.Although the incidence of aGVHD was higher in ABO-incompatible group than that in ABO-compatible group,but there was no effect on engraftment,incidence of cGVHD or prognosis.

Object To investigate the saccharide changes of Radix Rehmanniae when being processed. Methods The fresh roots were torrefied at 65 ℃ and sampled at 0,1, and 6 d. The samples and 4 h steamed slices of those dried roots were extracted with hot water respectively. The extracts were subjected to HPLC analysis, Sugar pak 1 column at 80 ℃,with water as the mobile phase at 0 7 mL/min and detected by RID. Results There are three principal components in the fresh roots, i.e. stachyose (11%-15%), sucrose (0 30%-0 92%), and catalpol (0 27%-0 88%). In the processing of the fresh roots, the HPLC chromatorams of the extracts differed to each other remarkbly. On the chromatogram of roots torrefied for 1 d, one distinct monosaccharide peak displayed at 10 2 min, which is likely to be galactose, and it become prominent in the dried roots together with raffinose. In steamed ones, the peaks of fructose and glucose became outstanding. Conclusion According to the HPLC chromatograms, the degalacto sylation of stachyose may take place during torrifying, while defructosylation during steaming. One of the principal purposes of the processing may be for stachyose degradation for its flatulence causing character.

Objective:To summarize the oblique branches found in the transfer of anterolateral thigh flap (ALTF) and to handle the issues of oblique branch.Methods:Thirty patients who require surgery of ALTF transfer from May, 2017 to October, 2019 were enrolled. CTA examination was perfected prior surgery and the origin of ALTF vessels was preliminarily determined. During the surgery, Three-longitudinal-and-five-transverse methods were used to locate and design the flap. The ALTF was taken according to the flap design. Attention should be paid to the location of the oblique branch and the separation of the vessels of oblique branch to avoid a damage as much as possible. The vessels of oblique branch should be completely explored and separated. One or 2 vascular pedicles were cut according to whether the oblique branch vessels and the descending branch vessels were joined together during surgery. Clamping tests were carried out on the 2 vascular pedicles to determine an arterial blood supply. Super drainage of vascular pedicle veins according to the situation of blood circulation. After the surgery, routine treatment was carried out. Blood supply, skin temperature, swelling degree, exudation and survival of the flap were closely observed and regular follow-up was carried out.Results:Among the 30 ALTF examined by CTA, 13 patients were identified with oblique branch vessels before operation. During operation, 11 oblique branch vessels (The occurrencce rate was 36.6%)were found to enter the flap, and were completely preserved. Of the 11 identified oblique branch vessels, 8 had 2 vascular pedicles taken and the vascular pedicles were treated by venous super drainage technique. The postoperative blood supply of the flap was good; The skin temperature was closed to surrounding normal skin; Swelling of flap was minor and there was little seepage. The flaps all survived after surgery with stage one healing. Followed-up time was 3-32 (average 16.1) months. The recipient site healing was good, and the function and appearance were satisfactory. The joint movement at the donor site was normal, and there was no obvious loss of local sensation.Conclusion:More than one third of the oblique branches appear in this group. The oblique branch vessels should be preserved as much as possible to avoid issues in relation to the oblique branch. Reasonable handling of oblique branch is the key to the success of the surgery.

Objective To investigate the evidence of cortical reorganization in stroke hemiplegia treated with constraint-induced movement therapy(CIMT)by fMRI.Methods Five patients with chronic stroke were evaluated with the Action Research Arm Test(ARAT).The functional MRI(fMRI)was performed on a 3.0-T MRI with echo-planar imaging.The subjects were required to finish the finger-tapping task and undergo fMRI before and after CIMT.A block design was used for the inspection.Results After CIMT,the function of upper limb(sick side)of patients improved significantly assessed by ARAT(P<0.001),and cortical reorganization was found on fMRI.Conclusion CIMT can improve motor function of upper limb of chronic stroke patients with hemiplegia and induce cortical reorganization as measured by fMRI.

ObjectiveTo investigate the effect of β-adrenergic receptor(β2AR) stimulation on vascular smooth muscle cell apoptosis in physiological state and receptor overexpression model.Methodsβ2AR overexpression model was established by transgenic techniques. Hoechst 33342 staining as well as flow cytometer(FCM) detected were chosen to measure the incidence of vascular smooth muscle cell apoptosis.ResultsVascular smooth muscle cell exhibited significantly fewer viable cell rate when stimulated with β2AR agonist isoproteronol for 48 hours compared with control (P<0.01),while no difference at the time point of 24 hours. Much fewer viable rate detected by FCM and high apoptotic rate by Hoechst staining were observed when VSMCs overexpressing β2AR were stimulated with isoproteronol for 24 hours (P<0.01).ConclusionStimulation of physiological and overexpressing β2AR could induce apoptosis of vascular smooth muscle cell.

The aim of this study was to investigate the effect of Bu-Shen-An-Tai recipe (BSATR) and its two components (Bushen recipe, and Huoxue recipe) on endometrial morphology during peri-implantation in superovulated mice. Mice were randomly divided into five groups, including the normal (N), model (M), Bushen (BS), Huoxue (HX) and Bu-Shen-An-Tai (BH) groups. The uteri were collected on day 4 of pregnancy, and the endometrium thickness, microvessel density (MVD) and number of pinopodes observed. Compared with the M group, the endometrial thickness in the BS, HX and BH groups was significantly increased and there was a significant difference in endometrial thickness between the BS and the BH groups. The mean MVD was significantly lower in the M group than in the N group, and there was a significant increase in MVD in the BS, HX and BH groups as compared with the M group. Compared with the M group, the pinopode scores in the endometrium were significantly increased in the HX and BH groups; and the BS group had significantly higher pinipode scores than the HX and BH groups. In conclusion, the results of the present study demonstrated that the recipes (Bushen, Huoxue and BSATR) could improve the endometrial environment by regulating the endometrial thickness, MVD and the number of pinopodes at the window of implantation. Moreover, the Huoxue recipe and the BSATR were more efficient than the Bushen recipe, with the BSATR tending to have the most beneficial effects.
