Tyrosine kinase inhibitor (TKI) may significantly improve the treatment outcome in chronic myeloid leukemia (CML).It is the most frequent question about whether the patients with durable complete molecular response (CMR) can safely discontinue TKI treatment without relapse.This has focused attention on the strategies to eradicate residual CML cells,especially the CML stem cells,which should result in long term leukemia-free survival and permanent cure.Here,the progress on discontinuation of TKI therapy and alternative approaches to eradicating CML stem cells in the 55th ASH annual meeting is reviewed.

Objective To compare the clinical efficacy of three different concentrations of ropivacaine combined with morphine and granisetron on postoperative patient controlled analgesia by epidural anesthesia.Methods Ninety postoperative patients were randomly divided into three groups with 30 cases each.The patients in group Ⅰ received 0.25% ropivacaine,in group Ⅱ 0.20% ropivacaine,in group Ⅲ 0.125% ropivacaine.Each group combined with morphine(6?g/ml) and ciranisetron(0.03mg/ml).The patients controlled epidural analgesia(PCEA) continually infused of 2ml/h.Motor block(in limb) was assessed with Bromage scale.Results Visual analogue scales(VAS) were observed at 6,12,24 and 48h postoperatively.Pain score was higher in group Ⅲ than that in group Ⅰ and Ⅱ.Motor block by Bromage scale was higher in group Ⅰ than that in group Ⅱ and Ⅲ.Each group had no anesthetic complication.Conclusion PCEA by 0.20% ropivacaine combined with morphine and granisetron can provide a good postoperative analgesia and have no significant motor retarded.It is worth popularizing.

Objective To study the effect of Nurrl gene on the differentiation of rats' marrow stromal cells(MSCs) into neurous under the co-inducement of total panax notoginserg saponins(tPNS) and all-trans-retineic acid(ATRA) by coloning the Nurrl gene and transfecting it into MSCs. Methods Expressing plasmids pcDNA3.1-hygro-Nurrl were cloned,then transfected into MSCs with lipofectamine 2000.To begin with,MSCs were subcultured into 6-wells cultured plate at about 5?10~5 cells/well density and the wells were divided into four groups randomly which were Nurrl+tPNS/ATRA group,tPNS/ATRA group,Nurrl group and control group.Secondly,the plasmids were introduced to the MSCs in Nurrl+tPNS/ATRA group and Nurrl group,then protein expression of Nurrl was identified with immunocytochemistry.Thirdly,after the MSCs and plasmids had been co-cultured for 48 hours,cells in Nurrl+tPNS/ATRA group and tPNS/ATRA group were induced with BME in advance then with tPNS/ATRA in due form.For cells in Nurrl and control group,the only difference was that tPNS/ATRA was replaced with the culture.Finally we compared the different percentage of positive cells in four groups with TH,AChE and GABA antibodies by immunocytochemistry method. Results The immunocytochemical test showed that the MSCs transfected with Nurrl gene expressed Nurrl protein.The percentage of positive cells of TH antibody in Nurrl+tPNS/ATRA group was(38.4?4.6)% distinctly higher than that of tPNS/ATRA group,which was(5.9?3.4)%.Conclusion With tPNS/ATRA induced and immunocytochemistry of TH,positive cells percentage in Nurrl+tPNS/ATRA group was higher than that in tPNS/ATRA group,which showed a statistic difference.And the inducing function of tPNS and ATRA in MSCs differentiating into neurons was definite.

This paper reported one case with deposition of schistosome eggs in lymph nodes of rectal cancer draining area.

Objective To clone and express Schistosoma j aponicum cyclophilin B (SjCyPB) gene in E.coli,and to identify and analyze the immunity of recombinant proteins.Methods A pair of specific primers was designed according to GenBank of Schistosoma japonicum sequence.SjCyPB gene was amplify by PCR and then connected to pET28 vector.The recombinant plasmid pET28a (+)-SjCyPB was constructed and transformed into E.coli BL21 cell line,the recombinant plasmid was identified by double enzyme digestion and sequence analysis.After induced by isopropyl-B-D-thiogalaetoside (IPTG),the expressed recombinant proteinwas purified by affinity-chromatography,and then verified by Western blotting.Rats were immunized recombinant SjCyPB,andthe SjCyPB-specific IgG was detected by ELISA.Results SjCyPB gene was successfully inserted into pET28a(-) vecter which identified by double enzyme digestion and sequence analysis.Recombinant SjCyPB protein was highly expressed in E.coli.The Western Blotting analysis confirmed that the recombinant protein could specifically combine to S.japonicum-infected rabbit serum.Using recombinant protein to immunize rats,the SjCyPB-specific IgG antibody titer was 1 ∶ 51 200 detected by ELISA.Conclusion The recombinant SjCyPB is successfully constructed,and recombinant SjCyPB has immunogenicity and antigenicity.

With the illustration of the L-Arg-NO-cGMP pathway in penile erection,the researches on nitric oxide synthases(NOSs),which produce nitric oxide(NO)as the main messenger to control the process,has stayed in the spotlight.nNOS locates in neuroal tissues and eNOS is binding on the membrane of cavernous sinus endothelium with caveolin.The nNOS & eNOS are expressed constitutively.The activation of nNOS & eNOS is more dependent on Ca2+ concentration than iNOS,which is seldom expressed except in aged or pathological conditions.It is now clear that nNOS may initiate cavernosal tissue relaxation under the regulation of PDZ zone when transcripted,while phosphorylated eNOS may facilitate attainment and maintenance of full erection.iNOS expression stimulated by the cytokines may be beneficial(cytoprotective or anti-fibrotic)or deleterious(cytotoxic)according to the tissue environment.Gene therapies based on NOSs have attained a great deal of achievements in animal experiments and will promise a wonderful future.

OBJECTIVE:To discuss the effects of Rujieping capsule on estrogen receptor(ER) and progesteron receptor(PR) of pathological tissues in rats with hyperplasia of mammary glands.METHODS:The rats were injected i.m with Estradiol benzoate injection for 25 days followed by the injection of Progesterone injection i.m for 5 days to establish the model of hyperplasia of mammary glands.Which were treated with high and low doses of Rujieping capsule respectively for 30 days with tamoxifen as positive control.RESULTS:Both tamoxifen and high and low doses of Rujieping capsules could lessen the symptoms of red swelling of nipples or hyperplasia of mammary glands,lower the levels of E2 and PRL,enhance the level of progestone,lower the index of uterus,markedly reduce the number of layers of the ductal epithelial cells,reduce the levels of ER and PR in mammary glands,and suppress mammoplasia.CONCLUSION:Rujieping capsules is effective in the treatment of hyperplasia of mammary glands in rats by regulating the level of estrogen and improve pathomorphologic change of hyperplastic mammary glands.

OBJECTIVE:To study the immunoregularoty effect of Lappaconitine in S180 tumor-bearing mice.METHODS: Each mouse was inoculated hypodermically with S180 tumor cells and normal sodium suspension,24 hours later,all the mice were injected i.m.with Lappaconitine q.d for 10 consecutive days.The immune function of the S180 tumor-bearing mice was detected.RESULTS: In Lappaconitine-treated mice,serum IgG level was heightened significantly;the 2,4-DNFB-induced delayed type hypersensitivity was enhanced;the induction of transformation of lymphocytes into lymphoblast was achieved;the phagocytic function of reticuloendothelial system was enhanced significantly,and the immune function of red cells was promoted.CONCLUSION: Lappaconitine could inhibit the growth of S180 tumor cells and significantly enhance the cellular immune function of S180 tumor-bearing mice.

OBJECTIVE:To discuss the health risk links involved in self-medication of Chinese urban residents. METHODS: Based on literature study and the experts consultation, the high risk links of the self-medication were defined according to the process of self-medication behavior and the probability of the health harm involved in the self-medication behavior, and the intervention suggestions were put forward for the health risks. RESULTS & CONCLUSIONS: The health risk links involved in self-medication of Chinese urban residents appear as 6 links include self-diagnostic error, incorrect drug choice, failing to understand or follow drug package inserts in taking drugs, irrational drug use, unaware of the drug contraindication, disregarding the physiological particularity of the special drug users. Carrying out education on self-mediation and behavior management among the residents, and reinforcing the government control are the effective ways to reduce the health risk of self-medication.
