1.0 mmol/L).The clinical side effects after medication circa were compared between two groups.Results There was no significant difference in myelosuppression,liver functional lesion,gastrointestinal tract reaction and infection in 2 groups.But following the increase of MTX blood drug level,the incidence rate of skin mucosa contamination,electrocardiographic abnormality,the cardiac creatase abnormity and nervous system symptoms significantly increased.Conclusions In the course of child ALL treatment with HD-MTX+CF,the side effects are common and individual difference is obvious.Specific treatment on individuals is suggested.J Appl Clin Pediatr,2006,21(3):170-171

AIM: To observe the expression of transforming growth factor ? 1 (TGF-? 1), MAPK 1/3 and fibronectin (FN) in the development of renal tubulointerstitial disease. METHODS: Wistar male rats were randomly divided into normal control group, diabetic group of 1week, 2 weeks, 4 weeks and 8 weeks. Diabetic model was induced by peritoneal injection of streptozotocin. Immunohistochemistry was employed to detect the expression of TGF-? 1, MAPK 1/3 and FN in the kidney. TGF-? 1 protein in the renal cortex was checked by Western blot. BG, Scr and UP were analysed by biochemical methods, and the morphological changes in renal tubulointerstitium were also examined under microscopy on sections stained with HE and PAS. RESULTS: The expression of MAPK 1/3 and FN was observed, but not the expression of TGF-? 1 in normal renal tissue. Positive staining of TGF-? 1 was observed in the renal tubulo-interstitium in 1-week diabetic group and thereafter it increased in the course of diabetes. A continuous increase in the expression of MAPK 1/3 and FN was also observed in two - week diabetic rats. Chronologically the expression of TGF-? 1,MAPK 1/3 and FN and the ratio of KW/BW were positively correlative with each other in diabetic animals except one -week diabetic rats. There was also a positive correlation between MAPK 1/3 and FN in l -week diabetic rats. CONCLUSION: Our data suggest that TGF-? 1 appears in the renal tubulointerstitium in early period of diabetes and then its signal is mediated by MAPK 1/3 cascades to accelerate production of FN ,and in turn leads to renal hypertrophy and tubulointerstitial fibrosis.

OBJECTIVE: To explore the effects of Tanreqing injection, a traditional Chinese herbal preparation for clearing heat and resolving phlegm, in treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) by improving airway inflammation and airway mucus hypersecretion. METHODS: A randomized controlled trial (RCT) was designed. Ninety AECOPD patients were randomly divided into Tanreqing group, ambroxol hydrochloride group and control group. The patients in the three groups were all treated with conventional therapy. Furthermore, intravenous drip infusion of 20 ml Tanreqing injection (once daily) and 15 mg ambroxol hydrochloride injection (twice daily) were administered respectively to the patients in the Tanreqing group and ambroxol hydrochloride group. They were all treated for 10 days. Symptom score of traditional Chinese medicine (TCM), plasma concentrations of interleukin-8 (IL-8), IL-10 and neutrophil elastase (NE) were detected before and after treatment. RESULTS: Cough, sputum amount, expectoration, dyspnea, fever, coated tongue and pulse tracings were improved obviously in Tanreqing group (P<0.05), and the effects of Tanreqing on improving cough, sputum amount and expectoration were better than the conventional therapy (P<0.05), while there was no significant difference between Tanreqing group and ambroxol hydrochloride group (P>0.05). Compared with ambroxol hydrochloride group and the control group, the coated tongue was improved obviously in Tanreqing group (P>0.05). After treatment, plasma concentrations of IL-8, IL-10 and NE were decreased in Tanreqing group and ambroxol hydrochloride group (P<0.05), and the levels of IL-8 and IL-10 in the control group were decreased (P<0.05). The change of IL-8 level before and after treatment in Tanreqing group was greater than that in ambroxol hydrochloride group and the control group. The changes of IL-10 and NE levels in ambroxol hydrochloride group were greater than those in Tanreqing group and the control group, while there was no significant difference in the changes of serum levels of IL-8, IL-10 and NE among the three groups (P>0.05). Total response rates in Tanreqing group and ambroxol hydrochloride group were higher than that in the control group (P<0.05), while there was no significant difference in total response rate between Tanreqing group and ambroxol hydrochloride group (P>0.05). There was no significant difference in total response rate among the three groups (P>0.05). CONCLUSION: Tanreqing injection can improve TCM signs and symptoms in AECOPD patients, and the mechanism maybe due to the decrease of serum levels of IL-8 and NE and improvement of IL-10 level.

OBJECTIVETo observe the efficacy and safety of Danlong Oral Liquid (DOL) combined Western medicine (WM) in treating mild-to-moderate bronchial asthma patients (heat wheezing syndrome) at acute onset.

METHODSTotally 480 mild-to-moderate bronchial asthma patients (heat wheezing syndrome) at acute onset were randomly assigned to two groups in the ratio 3:1, the treatment group (360 cases) and the control group (120 cases). All patients received basic WM treatment. Patients in the treatment group took DOL, 10 mL each time, 3 times per day for 7 days in total, while those in the control group took Kechuanning Oral Liquid (KOL) , 10 mL each time, 3 times per day for 7 days in total. Efficacy for asthma symptoms, lung functions and scores of TCM syndrome and/or main symptoms were evaluated.

RESULTSThe percentage of clinical control and significant effectiveness of asthma symptoms in the treatment group was significantly higher than that of the control group (77.36% vs 56.07%, P < 0.01). The percentage of clinical control and significant effectiveness of lung functions in the treatment group was significantly higher than that of the control group (74.28% vs 50.00%, P < 0.01). The anterior-posterior difference in scores of TCM syndrome was significantly superior in the treatment group than in the control group (-11.26 ± 4.70 vs -9.21 ± 5.09, P < 0.01). The anterior-posterior difference in scores of main symptoms was significantly better in the treatment group than in the control group (-6.58 ± 3.08 vs -5.16 ± 3.45, P < 0.01). The incidence of adverse reactions was significantly lower in the treatment group than in the control group [1.73% (6/346 cases) vs 10.17% (12/118 cases) , P < 0.05].
