Objective To search for a way of treating chi1dren's idtopathic nephrotic syndrome (INS) hypoadrenocorticismand its significance. Meethods Thirty-nine patients (31 males and 8 females) with INS were randomly divided into twogroups: 21 patients in tera-peutic group (treated by prednisone, astragali and acanthopanax root) and 18patients in control group (Simply treated by prednisone). 1ml blood was respectively drawn from all thepatients at 8 o'clock (one time before treatment and one time after treatment), the serum cortisol wasdetermined by radioimmunoassay (RIA). Results In control group, the levels of serum cortisol still remained lower than the normal value aftertreatment and the levels after large dosages prednisone treatment were markedly lower than that beforetrea-tment. The values of serum cortisol returned to be normal after treatment in therapeutic group. Conclusion Astragali and acanthopanax root can restore the hypoadrenocorticism in children with INS.

Objective To investigate the clinical characteristics,pathogen distribution and outcome of lower respiratory tract fungal infection in patients with mechanical ventilation in emergency intensive care unit(EICU). Methods The clinical data of patients with lower respiratory tract fungal infection treated with mechanical ventilation in EICU were retrospectively analysed. Results Eighty(64.5%) of the 124 patients with mechanical ventilation experienced lower respiratory tract infection,among whom 21(26.2%) were complicated with fungal infection.The predominant pathogen was Candida(Candida albicans,n=11;Candida tropicalis,n=5;Candida smooth,n=3;Candida parapsilosis,n=2).Compared with patients with non-fungal infection(n=59),those with fungal infection(n=21) had higher APACHE II score,longer mechanical ventilation time and longer ICU stay duration(P

Object To define the molecular characters of differentiating Bupleurum chinense DC., B. scorzonerifolium Willd. from their allied species B. marginatum Wall. ex DC., B. smithii Wolff var. parvifolium Shan et Y.Li. and B. longiradiatum Turoz. Methods General DNA was isolated from fresh leaves of Bupleurum L. species by CTAB. The random amplified polymorphic DNA (RAPD) was used to identify them. Results Five Bupleurum L. species can be identified by primer OPA-1(5'-CAGGCCCTTC-3'), OPD-8 (5'-GTGTGCCCCA-3'), OPD-11 (5'-AGCGCCATTG-3'). Conclusion The method of RAPD can be used to identify the Bupleurum L. species and its allied species.

AIM:To establish an HPLC-ELSD method for determing dulcitol and astragaloside in Compound Fufangteng Capsules(Radix et Rhizoma Ginseng rubra,Radix Astragali,Herba Euonymi,etc).METHOD:Chro-matographic conditions included Lichrospher 5-NH_2 column(250 mm?4.6 mm,5 ?m)and the mobile phase consisting of a mixture of acetonitrile-water(91 ∶9).The flow rate of mobile phase was 1.0 mL/min.The column tempe-rature was at 28 ℃.Detector:PL-ELS2100 ELSD(Eva:65 ℃,Ned:50 ℃,gas flow:0.9 L/min).RESULTS:The linear ranges of dulcitol and astragaloside were 2.91-29.1 ?g(r= 0.999 8)and 1.03-10.3 ?g(r= 0.999 1),respectively.The average recoveries of dulcitol and astragaloside were 99.24% and 103.17% with corresponding RSD of 2.6 % and 1.8%(n=6),respectively.CONCLUSION:The method is steady and with good repeatability,and can be used to determine the content of dulcitol and astragaloside in Compound Fufangteng Capsules.

Objective To observe blood pressure variability(BPV) and analyze the correlation between BPV and carotid artery-intima media thickness (CA-IMT) in elderly hypertension. Methods Totally 156 patients with primary hypertension were divided into 3 groups:patients aged 45-59years (48 cases) 60-79 years (52 eases),and 80-94 years (56 cases).24 h ambulatory blood pressure monitoring (24 h ABPM) was used to measure 24 h mean systolic blood pressure (24 hSBP),24 h SBP standard deviation (24 h SBPSD),and to calculate 24 h SBP coefficient of variation (24 hSBP CV).Meanwhile,SBP of daytime (DSBP) and nighttime (NSBP),DSBPSD and NSBPSD were measured,and DSBPCV and NSBPCV were calculated.CA-IMT was examined by ultrasound.Spearman rank correlation coefficient was employed to assess the relationship between above indicators and CA-IMT,age. Results No differences were found in 24 h SBP,DSBP and NSBP among the groups.24 hSBPSD( 14.3 ± 3.1),24 h SBPCV ( 11.5 ± 2.1 ),DSBPSD ( 13.8 ± 3.8),DSBPCV ( 10.7 ± 2.6),NSBPSD (13.4±3.3)of patients aged 80-90 years were higher than those of patients aged 60-79 years (12.2±2.5,10.1±2.0,11.6±2.6,9.5±2.3,11.9±2.8)and patients aged 40-59 years (11.7±2.8,9.4±1.9,10.9±3.1,8.4±1.8,11.6±3.0) (P＜0.05).NSBPCVof patients aged 80-90years was increased as compared with patients aged 40-59 years (10.9±2.7 vs.9.6±2.4,P＜0.05).24 h SBPSD,24 h SBPCV were associated with CA-IMT and age(r=0.26,0.39;0.28,0.42,all P＜0.01). Conclusions SBPSD and SBPCV of 24 h ABPM are higher in very older patient with hypertension and could be the useful markers for assessment of BPV.

Objective To explore the microbial etiology of early onset pulmonary infection after liver transplantation.Methods The 40 episodes of early onset pulmonary infection in 75 patients receiving liver transplantation in our hospital were reviewed and analyzed retrospectively.Results The incidence rate of pulmonary infection was 53.30% in these patients.A total of 54 pathogens were isolated,including 41(75.9%)strains of bacteria and 13(24.1%)fungal isolates.Gram-negative bacillus ac- counted for 68.3%(n=28)of the bacterial isolates,11(39.3%)of which were positive for extended spectrum?-lactamase. Gram-positive coccus accounted for 31.7%(n=13).Seven (58.3%)of the staphylococcal strains were methicillin-resistant. Conclusions The incidence of pulmonary infection is high early af- ter liver transplantation.Most of the isolated pathogens are drug resistant.Culture of sputum or secretion of lower respiratory tract and bedside X-ray examination are useful for the diagnosis.

Objective To report two cases of mitochondrial disease presenting with marked gastrointestinal symptoms and mild myopathy without involvement of central nerve system as to investigating the diagnostic rules of the disease Methods Case 1 is a 13 year old boy who had suffered from recurrent vomiting with mild diarrhea and fatigue for 7 years Physical examination showed mild weakness of both legs without ophthalmoplegia and cognitive defects Radiological examination revealed gastroptosis with excessive peristalsis of small intestine Case 2 is of a 6 year old boy who showed repeatedly the recurrent vomiting, intestinal pseudo obstruction and persistent muscle weakness over 1 year and 7 months There were no ophthalmoplegia. Barium clysis showed marked dilatation of colon. Cranial MRI in case 1 and CT in case 2 were unremarkable Muscle biopsies were performed in both cases and specimens were studied using routine histological and histochemical staining as well as using ultrastructural examination mtDNA analysis were performed in both cases Results Histological and enzym histochemical staining showed RRF and SDH positive fibers in both cases. Electron microscopic studies revealed mitochondrial proliferation with paracystalline inclusions in the muscle fibers with mild accumulation of lipid and glycogen. Genetic study revealed point mutation in mtDNA 3243A→G in case 1 and mtDNA3271T→C in case 2 Conclusion Mitochondrial cytopathy might be diagnosed upon the myopathological and genetic findings Different from MNGIE, Leigh disease and MELAS, the main clinical features were gastrointestinal symptoms, mild muscle weakness and no involvement of central nerve system in our patients, thus the mitochondrial entero myopathy, a new clinicopathological type of mitochondrial disorders, might be considered Since the muscle weakness was usually overlooked in patients with diarrhea, the mitochondrial cytopathy occurring should be considered with more attention as to elucidating the causes of children who have chronic gastrointestinal symptoms
