OBJECTIVETo explore the feasibility of human leucocyte antigen (HLA) haploidentical related T-cell undepleted allogeneic bone marrow transplantation (Allo-BMT) combined with Chinese medicine for the treatment of leukaemia.
METHODSFour patients with chronic myeloblastic leukemia (CML) and 4 with acute myeloid leukemia (AML) received allo-BMT with graft from 1 - 3 HLA-mismatched related donors. All patients were pre-treated with standardized conditioning regimen consisting of high dose Ara-c, cyclophosphamide (CY) and total body irradiation (TBI) or busulfan. Donors were given G-CSF 250 microg/d for 7 days prior to marrow harvest. To prevent GVHD, besides application of CSA and MTX, ATG 2.5 mg/kg was given everyday for 4 days before transplantation, and MMF 1.0 g per day starting from the 7th day after transplantation. Chinese medicine for replenishing qi and yin and strengthening Pi and Wei was administrated orally after transplantation.
RESULTSSuccessful haematopoietic reconstruction was seen in all patients. The median days for reaching of granulocyte >0.5 X 10(9)/L and platelet > 20 x 10(9)/L were 12 (range 10-14) and 20 (range 18-25) days respectively. GVHD of skin in various grade was seen in 7 patients, among whom only one advanced to grade IV; besides, 2 accompanied with GVHD of gut, one with hemorrhagic cystitis, one died for concurrent infection on the 81st day, and one left hospital of his own accord on the 46th day. The median follow-up duration was 18 (range 2-32) months, during this period six patients were alive in a disease-free situation.
CONCLUSIONCombined therapy of HLA haploidentical related T-cell undepleted Allo-BMT and Chinese medicine plus immunosuppressants with pre-harvest G-CSF application in doner could effectively reduce the incidence of acute severe GVHD and raise the disease-free survival rate in treating leukaemia.

Objective To evaluate the effect of bone mesenchymal stem cells (BMSCs) on lidocaine-induced apoptosis in dorsal root ganglion cells (DRGCs) of rats in vitro.Methods DRGCs in the logarithmic phase were incubated in culture plates at the density of 2 × 104 cells/cm2 (27 wells in total).DRGCs were randomly divided into 3 groups (n =9 each) using a random number table:control group (group C),lidocaine treatment group (group L) and BMSC treatment group (group B).The DRGCs in group C were incubated routinely without lidocaine,while the DRGCs were incubated for 2 h with lidocaine with the final concentration of 50 mmol/L in L and B groups.The DRGCs were then incubated normally in group L.The DRGCs were then co-cultured with the BMSCs which were incubated in Transwell chambers with the density of 2 × 104 cells/cm2 in group B.DRGCs were collected at 48 h of incubation for detection of apoptosis by flow cytometry.Apoptosis rate was calculated.Results Compared with group C,the apoptosis rate was significantly increased in L and B groups (P < 0.05).The apoptosis rate was significantly lower in group B than in group L (P < 0.05).Conclusion BMSCs can reduce lidocaine-induced apoptosis in DRGCs of rats in vitro,indicating that BMSCs may reduce local anesthetics-produced toxicity to the peripheral nerve.

Objective To observe effect of lidocaine pretreatment to malondialdehyde(MDA) and endothelin(ET) of patient ac-cepeted brain tumor removing and discuss the optimized pretreatment time .Methods 60 brain tumor patients in the hospital from March 2009 to September 2011 .according to the different pretreatment time ,the patients were randomly divided into five groups :group A(preoperative 48 h) ,group B(preoperative 24 h) ,group C(preoperative 12 h) ,group D(0 h or anesthesia induced) ,group E (control group) and group F(blank control group) ,10 cases in each group .Group A ,B ,C ,D with 1% lidocaine 1 .5 mg/kg intrave-nous pretreatment on schedule ,then induced conventional anesthesia ;group E were supplemented with 1% lidocaine 2 .5 mg · kg -1 · h-1 intravenous injection after anesthesia induction ;group F was performed routine program without lidocaine .The spontaneous breathing time ,awake time and tracheal extubation time was recorded ,while NIHSS score for evaluation of neural function defect was applied ,and peripheral serum level of MDA and ET was detected by colorimetric technique and radio-immunity .Results In group C ,the spontaneous breathing time ,awake time and tracheal extubation time were shorter than other groups ,but the difference had no statistically significant(P>0 .05) .There was no significant difference among each group in the aspect of NIHSS score 1 day before surgery(P>0 .05) ,after 14 days of operation ,NIHSS of group C was statistically lower than that of group E and group F (P<0 .05) .Before anesthesia induction ,there was no significant difference among groups (P> 0 .05) .MDA and ET content in group C was significantly lower than those in other groups after surgery (P<0 .05) .Conclusion Lidocaine given 12 h before cere-bral ischemia has varying degree protection against cerebral ischemia-reperfusion injury .The protection has relation with the de-crease of MDA and ET content .

Referring to the rules for agricultural seed testing (GB /T 3543-1995) issued by China, the test of sampling, seed purity, weight per 1 000 seeds, seed moisture, seed viability and germination rate had been studied for screening seed quality test methods of Pesudostellaria heterophylla. The seed quality from different collection areas was measured. The results showed that at least 6.5 g seeds should be sampled and passed through 10-mesh sieve for purity analysis. The weight of 1 000 seeds was determined by using the 500-seed method. The phenotypic observation and size measurement were used for authenticity testing. The seed moisture was determined under the higher temperature (130 ± 2) degrees C for 5 hours. The seeds were dipped into 0.2% TTC sustaining 1 hour at 40 degrees C, then the viability could be determined. The break dormancy seeds were cultured on sand at 10 degrees C. K cluster analysis was applied for the data analysis, the seed quality from different collection areas grading of P. Heterophylla was described as three grades. The seed quality of each grade should reach following requirements: for first grade seeds, germination rate ≥ 86%, 1 000-grain weight ≥ 2.59 g, purity ≥ 87%, moisture ≤ 13.1%; for second grade seeds, germination rate ≥ 70%, 1 000-grain weight ≥ 2.40 g, purity ≥ 77%, moisture ≤ 14.3%; for third grade seeds, germination rate ≥ 41%, 1 000-grain weight ≥ 2.29 g, purity ≥ 76%, moisture ≤ 15.8%. The seed testing methods for quality items of P. heterophylla had been initially established, as well as the primary P. heterophylla seed quality classification standard.

Objective:To establish and identify humanized-SCID mouse model(hu-SCID).Methods:SCID mouse was treated by CTX to inhibit the hemocytopoiesis. With successive 4-day injection, human peripheral blood mononuclear cells(PBMC) were engrafted into SCID mouse through intraperitoneal injection. After 4, 8 and 12 weeks of engraftment, peripheral blood, spleen and liver tissues of engrafted SCID mouse were harvested. Human CD3~+, CD19~+ cells in peripheral blood were analyzed by inflorescence microscopy and FCM, human CD3~+, CD19~+ cells in spleen and liver tissues were observed by immune histochemistry, and human IgG level in SCID mouse serum was measured by ELISA.Results:After engraftment of 4, 8 and 12 weeks, human CD3~+, CD19~+ cells in SCID peripheral blood were identified by inflorescence microscopy and the percents were 31% and 10% respectively by FCM analysis. And these cells could be evidenced after 12 weeks later. Through immune histochemistry human CD3~+、CD19~+ cells were detected in mouse spleen but not in liver tissue. Furthermore the titer of human IgG in mouse serum was 390,1 100 and 1 040 ?g/ml at each time point respectively.Conclusion:Our experimental results demonstrated that a bona fide humanized SCID model was established.

Objective To understand the impact of environmental temperature on the infection of miracidia of Schistosoma japonicum to Oncomelania snails, and to estimate the lowest critical temperature for infection of snails with miracidia. Methods Oncomelania snails free of S.japonicum were collected from field,and exposed to miracidia at the ratio of 1∶20 under the different temperatures, such as 5,6,8,10,15,20℃.Snails were dissected to check if infected after exposured and kept in 25℃ for another 70 days. Results The infection rate of snails were 0,0.92,1.43,2.40,8.96,17.39% under the temperature of 5,6,8,10,15,20℃, respectively. The relationship between snail infection rate and temperature for infection was showed in the regression formulation of y=0.0622x 2-0.4035x+0.6703 (r=0.9988,P
