OBJECTIVE:To reference clinical utilization of amikacin of a hospital.METHODS:By retrospective survey,the clinical information of 30 inpatients who were treated with amikacin and received plasma concentration monitoring from Apr.2006 to Feb.2010 were analyzed statistically in respect of primary disease,results of pathogen culture and drug sensitivity test,dosages and usage,plasma concentration,clinical efficacy,adverse drug reactions,etc.RESULTS:Clinical response rate was 55.2% and dosage of amikacin was small as well as measured value and reference value of plasma concentration.No adverse drug reaction was observed.CONCLUSION:The proportion of amikacin should be increased and plasma concentration monitoring of amikacin should be strengthened.Individual regimen is realized to improve effectiveness and safety of drug use.

Objective To study the clinical significance of P - selection expression in children with viral encephalitis and the correlation between this expression and the cerebral infarction with critical viral encephalitis. Methods Flow cytometric was employed to detect the expression of P- selection on the surface of platelet membrane in 44 children with viral encephalitis(20 light patients and 24 critical patients) and 20 healthy control children. The area of the cerebral infarction was determined by computed tomographic scan in 20 patients with critical viral encephalitis. The correlation between the two variables was analyzed. Results The expressions of P - selection on the surface of platelet membrane on less than 5 days and on 2 weeks after the onset of viral encephalitis were significantly higher in critical patients than those in normal control children and light patients( P

Objective To investigate the roles of adrenomedullin(ADM) and endothelin-1(ET-1) in left-to-right shunt congenital heart disease(CHD) complicated with congestive heart failure(CHF).Methods Plasma ADM and ET-1 concentrations were measured by radioimmunoassay in heart failure stage and recovery period of 18 infants with left-to-right shunt CHD.Also 20 healthy infants acted as control group were measured.Results Plasma concentrations of ADM and EF-1 were significantly higher in heart failure stage of left-to-right CHD infants than those in their recovery period,and both in their heart failure stage and in their recovery period were higher than that in control group(P

A high active soybean isoflavone glucoside hydrolase-producing mould strain was isolated from spirit qu. Its optimal hydrolase-producing conditions were as follows: 2.5% wheat bran as carbon source, 1% NaNO3 as nitrogen source, initial pH7. 0, culture medium volume 40mL/250mL, inoculating quantity 8% , culture temperature 30℃, revolutions 160r/min and culture time 84h. The enzyme activity reached 82 U/mL. Cu2+ can inhibit Absidia sp. R strain from producing the hydrolase, the influence of other metal ions was not remarkable on it.

Abstract: Objective　To investigate the clinical and laboratory characteristics of pulmonary infection caused by Nocardia otitidiscaviarum. Methods　The clinical data of a patient with pulmonary infection caused by Nocardia otitidiscaviarum were reported, and the clinical characteristics, laboratory characteristics and drug sensitivity of pulmonary infection caused by Nocardia otitidiscaviarum were summarized in combination with the relevant literature at home and abroad from January 2010 to December 2022. Results　A 67-year-old female patient was admitted to the hospital on June 30, 2020 because of "repeated chest tightness and shortness of breath for 3 years, aggravated cough, expectoration and fever". The sputum, alveolar lavage fluid and blood of the patient were collected for culture, and the detected pathogenic bacteria were identified. There are pathogenic bacteria growing in sputum and alveolar lavage fluid, which are identified as Nocardia otitidiscaviarum by Autof ms mass spectrometer. According to the results of pathogenic bacteria and the patient's condition, meropenem combined with compound sulfamethoxazole tablets were given anti-infection treatment, and the patient's condition improved and discharged. Conclusion　The clinical manifestations and imaging features of nocardiosis are lack of specificity, and are prone to misdiagnosis and missed diagnosis. Etiology is the key to disease diagnosis, and clinical examination and culture should be conducted in time.

In this study, 31 Notopterygium incisum populations were analyzed using ITS sequences to investigate the genetic structure. The results showed that: the ITS region ranged in size from 634 to 635 bp and base composition was with high G + C content of 57.8%. Thirty-one polymorphic sites were detected from 402 sequences of 31 populations of N. incisum, and the proportion of polymorphic sites was 4.88%, in which parsimony informative sites were up to 12. And 31 haplotypes were identified based on these polymorphic sites. Molecular variance analysis (AMOVA) indicated that high genetic differentiation (57%) existed among population, and gene flow was low (N(m) = 0.38) among populations. Phylogenetic relationships of 31 haplotypes were analyzed using NJ method with N. forbesiias an out-group. Phylogenetic analysis showed that 31 haplotypes from different populations mixed together and did not form distinct geographically separated clades.

Objective To explore the correlation between Helicobacter pylori (Hp) infection and recurrent abdominal pain (RAP) in children over 6 years old and its relative treatment.Me-thods One hundred and eighty children over 6 years old with the diagnosis of RAP from Mar.2007 to Feb.2009 were selected,30 healthy children without RAP were taken as the healthy control group at the same period.14C-urea breath test (14C-UBT) was used to detect whether the patient was infected by Hp.The radical cure of Hp was given to the Hp-positive children with RAP,and the remission rate of children with RAP and the Hp negative rate were observed.Results The positive rate in RAP group was 58.33%,which was higher significantly than that in healthy control group(20.00%)(P0.05).The positive rate of those with and without bad eating habits were 45.56% and 12.78%,and the positive rate of with and without family gastrosis history was 49.44% and 8.89%,which both had significant difference between them(Pa

Objective To investigate the significance and distribution of lymphopenia and antilymphocyte antibody(ALA) in systemic lupus erythematosus (SLE) and to explore the role of ALA in lympho penia.Methods One hundred and ten in-patients who were admitted during February 2003 to February 2008 were retrospectively reviewed.Indirect immunofluorescence test was used to detect ALA.Results ① Lymphopenia (＜1.5×109/L) was observed in 68.2% patients.Lymphopenia was associated with skin rashes,serositis,renal involvement,NPSLE,leucopenia,ANA,ds-DNA antibody,ESR and IgG levels.The lymphocyte count and SLEDAI scores was more closely correlated than total white blood cell counts.②ALA was positive in 51/110 (46.4%) patients.ALA was associated with renal involvement,NPSLE,WBC count,C3 level decrease,ANA,dsDNA antibody and SLEDAI scores.Conclusion Lymphopenia is significantly associated with SLEDAI scores.ALA is possibly one cause of lymphcytopenia.In addition,ALA is also a parameter for disease activity,and is associated with organ involvement and outcomes.
