High dose chemotherapy(HDC) with stem cell transplantion(SCT) has been used widely to treat non-Hodgkin's lymphoma(HHL).Its curative effect has been confirmed by many trials.But controversy still exists,such as application of HDC for various NHL subtypes,the optimum opportunity and method for transplantation.HDC has become standard therapy for recuring cases which are sensitive to chemotherapy and was a suitable consolidation therapy after remission for high-risk cases.Allogenic bone marrow marrow transplantation,only used for some special cases,need further study.

Objective To study the clinical effect of triethanolamine cream in treatment of traumatic wounds and its effect on level of interleukin-2 (IL-2), interleukin-8 (IL-8) and tumor necrosis factor-α(TNF-α).Methods 88 patients with traumatic wounds were selected in our hospital from February 2015 to January 2016, those patients were divided into observation group and control group according to coin method.The control group was treated with alginate dressing, observation group were given triethanolamine cream for treatment.The levels of IL-2, IL-8, TNF-αand visual analogue scale(VAS) between the two groups were compared.The clinical curative effect of the two groups was evaluated.Results After treatment, the total effective rate of the observation group(90.91%) was significantly higher than the control group (68.18%).There were no significant differences in VAS scores between the two groups before treatment, 5, 10,20 days after treatment, the VAS scores of the two groups were significantly lower than before treatment (P<0.05), at 5,10,20 days after treatment, the VAS scores in the observation group were significantly lower than the control group (P<0.05).The level of IL-2 in the observation group were significantly higher than the control group, the levels of IL-8,TNF-αwere significantly lower than the control group (P<0.05).Conclusion Triethanolamine cream can increase the level of IL-2 and decrease the levels of IL-8 and TNF-αin patients with traumatic wounds, it can relieve the pain of patients and has good clinical curative effect.

Aim To establish and evaluate Sprague-Dawley (SD) rats model with yang-deficiency and constipation at the direction of traditional Chinese medicine theories. Methods Rats model with yang-deficiency and constipation were induced by orally administration of white vinegar and active carbon-ice water. Changes of model rats in common biological characteristic, the number and time of excretion stool, colonic electromyography, gastrointestinal hormones and intestinal neurotransmitters were observed. Results Compared to the control group: changes of the model group in common biological characteristic including abdominal distension, puffed and withered hair, sluggish response, falling body weight, black and dry stool; Excretion time of the first granule stool became longer; Number of excretion stool within six hours became shorter; Intestine pushing rate decreased, and secretion of gastrointestinal hormones and intestinal neurotransmitters disordered, etc. After being treated with Tongbianling, the syndrome and indexes of model rats markedly improved. After 6 days′ resume, the model group in the experiment of excreting stool had markedly signification in comparison with the control group. Conclusion SD rats model with yang-deficiency and constipation could be stably established by administering white vinegar and active carbon-ice water.

Objective To study the quality standard of different specifications of Frutus Aurantii Immaturus. Methods The contents of synephrine, volatile oil, total ash, acid- insoluble ash and water in different specifications of Frutus Aurantii Immaturus were determined by HPLC or other methods according the china pharmacopoeia. Results The contents of volatile oil and synephrine in different specifications of Frutus Aurantii Immaturus were obviously different, and in accordance with empirically traditional classification. The contents of the total ash, acid- insoluble ash and water were similar in the different specifications and the total ash content was lower than 7 % which was in accordance with that recorded in China Pharmacopoeia.Conclusion Volatile oil, acid- insoluble ash, water and synephrine with a definite content limit can be chosen as the parameters for the research of quality standard of Frutus Aurantii Immaturus, which will supply evidence for the medicinal trade and research of Frutus Aurantii Immaturus.

AIM:Titanium-Nickel shape memory alloy(TiNi-SMA) has memory,abradability and good biocompatibility. It has different osteotomy methods and biomechanics from routine distraction osteogenesis. In this study,the dog models of mandibular defects were established to explore the effect of TiNi-SMA distractor with different osteotomy methods on mandibular distraction osteogenesis. METHODS:The experiment was performed at the animal experimental center of Sun Yat-sen University from October to December 2005. ①Eight male adult Beagle canines of 12-14 kg were selected. A 1.5 cm?1.0 cm bone defect was made in bilateral mandible of each dog. The same size transport bone disc was created mesially by osteotomy on left side and corticotomy on right side. TiNi-SMA distractor was implanted to repair defect. ②One,four,and seven days,and nine weeks after operation,the canines were radiographed for histological analysis and bone formation was observed. RESULTS:Eight dogs were all included in the final analysis. ①Gross observation found the wounds healed well without infection in all experiment dogs. ②X-ray examination showed the bone transport disc on the right side of corticotomy moved to defect area gradually after operation and filled defect area on the whole on the 7th day after operation;The bone transport disc dislocated 1 day after operation and separated from defect area totally on the 7th day after operation on the side of osteotomy(left side). ③ Histological examination demonstrated bone formed in accordance with intramembranous ossification in distraction zone and bony connection between the transport disc and mesial mandible on right side;On the left side,there was a big defect at the area of both distraction and defect zone because of dislocated bone transport disc,and no obvious new bone regeneration was found. CONCLUSION:Corticotomy can be used to establish a successfully canine model of mandibular distraction osteogenesis.

Objective To investigate the effect of tetramethylpyrazine injection on serum ion and β2-GPI/ox-LDL in patients with IgA nephropathy.Methods 58 IgA nephropathy patients were randomly divided into two gorups with 29 cases in each group.The control group were treated by benazepril and conventional treatment of dipyridamole, the experiment group were treated on the basis of the control group with tetramethylpyrazine injection.10 days of 1 courses, 2 courses of treatment.The serum ion,β2-GPI/ox-LDL and renal function related indexes were tested.Results Compared with before treatment, the serum inorganic phosphorus,β2-GPI/ox-LDL, Scr, BUN, CysC levels and 24 h urinary protein quantitation were lower( P<0.05), the blood calcium level were higher(P<0.05).Compared with the control group, the serum inorganic phosphorus,β2-GPI/ox-LDL, Scr, BUN, CysC levels and 24 h urinary protein quantitation were lower(P<0.05), the blood calcium level were higher(P<0.05), the clinical effect were higher (P<0.05).Conclusion Tetramethylpyrazine injection can effectively decrease the serum phosphorus, β2-GPI/ox-LDL, SCR, BUN, CysC levels and urinary protein amount of patients with IgA nephropathy, elevate blood calcium levels, significantly improve renal function and with less adverse reactions.
