1 or 2 grade FL followed by a diffuse large cell lymphoma(DLCL) ot a Burkitt/Burkitt-like lymphoma is TL.TL maintains a phenotype suggestive of germinal center derivation.The most common immunophenotype is the same as that of FL, CD+10/bcl-6+. Obtaining a biopsy of TL is enhanced if the biopsy is directed to the site with the greatest SUV. The risk of transformation of about 30% at 10 years after the initial diagnosis of FL.The median duration of survival after transformation generally ranging from 1 to 2 years.HDCT-ASCT, allogeneic tranplantation,radioimmunotherapy and bendamustine are the possible therapy for TL.

OBJECTIVE: To observe the effect of Shenshuaining dispersible tablets on renal function of rats with chronic renal failure (CRF) induced by adenine and explore its action mechanism. METHODS: Seventy-two Sprague-Dawley rats (the ratio of male to female was 1∶1) were randomly divided into 6 groups: normal control group, model control group, Niaoduqing group, Shenshuaining dispersible tablets groups (high, middle and low doses). All groups except the normal control were fed with feed containing 0.5% adenine to estabish CRF model. After giving corresponding drugs for 7 weeks, the levels of nitric oxide (NO), total nitric oxide synthase (T-NOS), inducing nitric oxide synthase (iNOS), configuration nitric oxide synthase (cNOS), total superoxide dismutase (SOD), Cu/Zn-SOD and malonaldehyde (MDA) were detected. RESULTS: Compared with normal control group, the levels of NO,T-NOS, cNOS, T-SOD and Cu/Zn-SOD markedly decreased, and the iNOS and MDA contents were significantly increased in adenine-induced CRF rats. Shenshuaining dispersible tablets could markedly ameliorate the above indexes. CONCLUSION: Shenshuaining dispersible tablets could effectively ameliorate renal function. The mechanism might be related to the enhanced body's antioxidation abiliy, reduced damage of free radical and increased synthesis of cNOS and NO which possess protective effect on renal function.

Objective To investigate the effects of different duration of sevoflurane anesthesia in the neonatal period on the long?term cognitive function and hippocampal synaptic plasticity in rats. Methods Twenty?four pathogen?free healthy Sprague?Dawley rats of both sexes, aged 7 days, weighing 12-16 g, were divided into 3 groups ( n=8 each) using a random number table: control group ( group C) , sevoflu?rane anesthesia for 2 h group ( group S1 ) , and sevoflurane anesthesia for 6 h group ( group S2 ) . Group S1 and group S2 inhaled 2% sevoflurane for 2 and 6 h, respectively. Morris water maze test was performed at 30 days after the end of anesthesia ( postnatal day 37) to assess the cognitive function. After the end of the test, the rats were sacrificed, and hippocampi were isolated for determination of the expression of brain?de?rived neurotrophic factor ( BDNF) , postsynaptic density?95 ( PSD?95) and synapsin 1 in hippocampal tis?sues by Western blot. Results Compared with group C, the escape latency on 4th and 5th days of the test in group S1 and on 2nd-5th days of the test in group S2 was significantly prolonged, and the frequency of crossing the original platform was significantly decreased, and the time of staying at the platform quadrant was significantly shortened in S1 and S2 groups, the expression of BDNF, PSD?95 and synapsin 1 in hipp?ocampal tissues was significantly down?regulated in group S2 (P<0?05), and no significant change was found in the expression of BDNF, PSD?95 and synapsin 1 in hippocampal tissues in group S1 ( P>0?05) . Compared with group S1 , no significant change was found in the escape latency and frequency of crossing
the original platform (P>0?05), the time of staying at the platform quadrant was significantly shortened, and the expression of BDNF, PSD?95 and synapsin 1 in hippocampal tissues was significantly down?regula?ted in group S2 ( P<0?05) . Conclusion Short?time and long?time sevoflurane anesthesia both can induce long?term cognitive dysfunction in the neonatal period, and the severity is aggravated with prolonged anes?thesia; the partial mechanism is related to inhibition of the synaptic plasticity of hippocampal neurons of rats.

CONCLUSIONS:Clinical pharmacists guarantee the safety and ef-ficacy of drug use by adopting dose of anti-infection drugs,evaluating efficacy,monitoring adverse reactions and vancomycin plas-ma concentration,and assisting physicians to optimize treatment regimen.

BACKGROUND:Cytological studies show that bone marrow mesenchymal stem cel s play an important role in postmenopausal osteoporosis mechanism.
OBJECTIVE:To study the osteogenic differentiation in vitro of bone marrow mesenchymal stem cel s from ovariectomied osteoporotic rats.
METHODS:The osteoporotic animal model was established by performing ovariectomy in the 6-month-old female Sprague-Dawley rats. There were four groups:bone marrow mesenchymal stem cel s control group, bone marrow mesenchymal stem cel s osteoporosis group, bone marrow mesenchymal stem cel s osteogenic induction group and oseogenesis induction group. Bone marrow mesenchymal stem cel s were isolated from the rats of control group and oseogenesis induction group by means of the whole bone marrow adherence method and cultured to the 3rd generation. Then the bone marrow mesenchymal stem cel s were used in al the experiments. Cel morphology was observed under the inverted phase contrast microscope, cel cycle and proliferation index of bone marrow mesenchymal stem cel s were detected by flow cytometry. After osteogenic induction, the expression level of alkaline phosphatase was detected, and the fornation of calcium nodes of bone marrow mesenchymal stem cel s were marked by alizarin red staining.
RESULTS AND CONCLUSION:The cel s in the osteogenic induction group and oseogenesis induction group had the morphology of osteobalsts, and the change of morphology of the cel s in the oseogenesis induction group was relatively tardiness. The proliferation index in the control group was higher than that in the osteoporosis group (P<0.05);expression level of alkaline phosphatase in the osteogenic induction group was significantly higher than that in the oseogenesis induction group (P<0. 05), and the control group was significantly higher than the oseogenesis group (P<0.05). The alizarin red staining of the cel s in the osteogenic induction group was positive, while negative in the control group and the oseogenesis group;the staining in the osteogenic induction group was stronger than that in the oseogenesis induction group. These findings indicate that both the proliferative potential and the osteogenic potential of bone marrow mesenchymal stem cel s from the ovariectomized osteoporotic rats are decreased, which may be related with the ostoeporosis pathogensis of ovariectomied rats.
