Objective To approach therapy of acute lymphoblastic leukemia(ALL) complicating acute respiratory distress syndrome (ARDS) in children.Methods The therapy of seven children diagnosed as ALL complicating ARDS was analyzed, who were treated by anti-infection, methyllprednisolone, ambroxol and constant positive airway pressure (CPAP) assisted ventilation.Results Six cases were recovery and one was death. The cure rate was 85.7%. Conclusion The cure rate is high, when employing combined therapy to treat ALL complicating ARDS.

Objective To establish an HPLC method for the determination of plasma metformin hydrochloride and an HPLC/ESI-MS method for the determination of plasma glibenclamide in human. Methods The metformin plasma samples were added with acetonitrile to denature proteins and the supernatant was injected into the system directly by using EC 250/4.6 NUCLEOSIL 100-5 analytical column (4.6 mm?250 mm, 5 ?m) with a mobile phase of 0.03 mol/L (NH 4) H 2PO 4∶acetonitrile (75∶25, pH 7.0) at the flow rate of 1.0 ml/min and the detection wavelength of 240 nm. Using glipizide as a internal standard, the glibenclamide plasma samples were extracted with ethyl acetate and determined by LC-MS using a chromatographic column ORBAX SB300C 18 (2.1 mm?150 mm, 5 ?m) with a mobile phase of acetonitrile-0.1% ammonium acetate (55∶45, V/V) at the flow of 0.2 ml/min. Results The glibenclamide concentration had a good linear correlation in the range of 2-200 ng/ml (r=0.999 8) while the metformin concentration in the range of 6.25-4 000 ng/ml (r= 0.999 9 ). Both the inter-day and intra-day RSD of metformin and glibenclamide were lower than 5%. Conclusion The assays have been proved to be sensitive, accurate and convenient and can be used in the study of human pharmacokinetics of glibenclamide and metformin hydrochloride.

Objective To observe the clinical effect of dexmedetomidine combined with butorphanol in preventing tourniquet reaction.Methods Fifty patients(ASA Ⅰ-Ⅱ)with upper limb operation and satisfactory effect of brachial plexus block were randomly divided into the dexmedetomidine group(A)and dexmedetomidine combined with butorphanol group (B),25 cases in each group.The anesthesia drug preparation method in the group A:dexmedetomidine 200μg was added with normal saline 50 mL;in the group B:dexmedetomidine 200 μg,butorphanol 1 mg and normal saline 50 mL altogether.The group A used dexmedetomidine 1 μg/kg load for 15 min and maintained by 0.4 μg · kg-1 · h-1 until the end of operation;the group B was given 0.015 mg/kg butorphanol,then was given medication according the scheme of group A.The VAS score,BIS value,Remsay sedation score,HR,MAP and SPO2 were recorded at the time points:before medication (T0),immediately after the tourniquet inflation (T1),15 min (T2),30 min (T3),45 min (T4),60 min after tourniquet inflation (T5) and 10 min after deflation (T6).The subjective response classification count,respiratory depression,bradycardia and hypotension in the two groups were assessed.pH,PaO2,PaCO2,HCO3-and LAC at T6 were evaluated by theblood gas analysis.Results The VAS score,BIS value,Ramsay sedation score,HR and MAP at T4,T5 had statistical difference between the two groups (P＜0.05).In the group A,the good and poor subjective responses had 9 cases and 4 cases respectively,which in the group B had 13 cases and 1 case,the difference was statistically significant (P＜0.05);there was no respiratory depression,bradycardia and hypotension in the two groups;the blood gas analysis showed no statistical difference between the two groups.Conclusion Applying dexmedetomidine combined with butorphanol in upper and lower limb surgery under brachial plexus anesthesia can significantly prevent the tourniquet reaction,its effect is superior to single use of dexmedetomidine.

To study changes of lung function for 10 years in the elder patients with chronic obstructive pulmonary diseases (COPD) who have quitted smoking for more than 10 years, 45 elder patients with COPD who had quitted smoking for more than 10 years were selected, and 11 elder patients with COPD who had never smoked were enrolled too. Routine lung function tests were performed. Initial values of VC, FVC, FEV 1 , PEF, MMEF, and MVV were compared with those 10 years later, and it was found the difference was significant ( P

OBJECTIVETo elucidate the necessary and research of accelerating basic research of Chinese standard pieces as standard materials.

METHODAccording to over 10 years accumulated experience and be keenly aware of the author, the evaluation method of standardized processing technology and Chinese pieces quality, aimed at consummated the standard material of the quality evaluation of Chinese herbal pieces at the current situation, and inaccordance with the need of improving quality standard system of Chinese herbal pieces, illustrate the necessity of accelerating basic research of Chinese standard pieces as standard materials; from the technical specification for collecting and processing of raw materials, and the technical specification, homogenized sample, packaging, storage and etc., for processing of candidate standard pieces, determine the methods and steps of technical specifications for standard pieces as the standard substance, determine the methods and steps of technical specifications for standard pieces as the standard substance.

RESULT AND CONCLUSIONTo speed up the basic research of standard of Chinese medicine pieces as of standard material is very necessary. The research objective is to specificate the processing technical for a number of standard pieces, to identify technical specifications and to ascertain the guiding principle and technical specification of decoction pieces as standard substance. This research will provide basic scientific data relevant national departments to apply for the accreditation of the standard substance.

ObjectiveTo comprehensively evaluate the curative effect ofTCM reating type 2 diabetes with three type dialectical therapy by Fuzzy Mathematics.Methods261 cases of 2 type diabetes were divided into three groups by syndrome differentiation,as follows:type of heat with yin deficiency,type of deficiency of both qi and yin,and type of deficiency of both yin and yang,and received corresponding therapies.The course of treatment was 24 weeks,in the first 12 weeks (period 1),on the basis of western medicine treatment,patients of the three groups were respectively treated by qingrungranules,ziyigranule and shuangtiaogranules.In the next 12 weeks (period 2),all patients were only treated by western medicine.The value of FBG,P2BG,HbAlc,TC,TG,BMI of the two periods were comprehensively evaluated by the methods of fuzzy mathematics.ResultsAt the end of period 1,the total effective rate of the type of heat with yin deficiency was 91.38％,the type of deficiency of both qi and yin was 87.16％,and the type of deficiency of both yin and yang was 83.34％; while at the end of period 2,the total effective rate of the three types was 59.18％,48.65％a nd32.65％ respectively.ConclusionThe effective rate was obviously improved in period 1; while in period 2,the effective rate was decreased.

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

Objective:To observe the effects of soybean isoflavones(SI) on uteri and uterine Er?,ER? expression in perimenopausal rats. Method:Female SD rats in age of 7-month-old were used as control and 11-month-old SD rats were divided into 5 groups,model group,diethylstilbestrol group and 3 test groups exposed to three doses of SI(ig:30,12,4.6 mg/kg?d) respectively for 35 d. Serum concentrations of estradiol(E2) ,testosterone(T) ,follicle-stimulating hormone(FSH) and luteinizing hormone(LH) were determined. Ultrastructure of uterine luminal surface was observed by scanning electron microscopy and hematoxylin-eosin staining. Expression of ER? and ER? in the uteri were determined by immunohistochemistry. Results:Low dose SI significantly increased serum E2(P
