China Pharmacy 2005;0(20):-
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

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.

Fermentation for Eicosapentaenoic Acid(EPA) production by Nitzschia laevis at various temperature between 10℃ and 30℃ was investigated and the dynamics characteristics during fermentation process were also analyzed.Based on the results,a varying temperature nursing method of two stage control strategy is proposed:During the first stage,which comprises the delay phase and the initial index phase,the temperature is maintained at 25℃;then the temperature is shifted to 20℃ and kept up till the end of the fermentation process.By this method,a EPA content of 6.0% and a yield of 291.60 mg/L have been gained.These are 24.07% and 18.81% higher than that of fixed temperature(25℃) fermentation,respectively.

Objective:To analyze the relationship between hepatitis B virus(HBV)gene mutation at 1896 in precore region with genotype and replication of HBV and the liver function of patients.Methods:HBV precore 1896 site mutation,the genotype of HBV and serum content of HBV DNA were determined by PCR in 60 patients positive of HBV DNA.Chemiluminescence miacropaticle immunoassay(CMIA)was used for detection of serum HBeAg and HBeAb.Liver function parameters were ob- tained by routine biochemistry method.Results:The alanine aminotransferase(ALT)level in HBV with 1896 site mutation was significantly higher than that in the wildtype virus.Site mutation at 1896 had no correlation with HBeAg,HBV genotype and HBV DNA content.HBV DNA content in patient with genotype C was significantly higher than that with genotype B(P
