Objective To set up the filter mating method of plasmid conjugation experiment for Corynebacterium.Methods The first plasmid conjugation between different genus was performed by filter method.Three strains of highly erythromycin-resistance Enterococcus faecalis isolates[minimal inhibitory concentration(MIC)of erythromycin>256 mg/L,MIC of levofloxacin≤8 mg/L] which screened by agar dilution method were used as donators and 3 strains of Corynebacteria isolates(MIC of erythromycin≤32mg/L,MIC of levofloxacin=128 mg/L)were used as acceptors.In the second conjugation between the same genus but in different species,three Corynebacterium xerosis strains(MIC of erythromycin>256 mg/L,MIC of ceftazidime=16 mg/L)which were conjugants of the first conjugation were used as donators and 6 strains of Corynebacteria isolates(MIC of erythromycin≤32 mg/L,MIC of ceftazidime 128 mg/L)were used as acceptors.Results In the first conjugation between different genus,the plasimid conjugations were done for 9 times between 3 donators and 3 acceptors,4 of which gained the phenotype and genotype of resistance and the transfer rate was 44%.In the second conjugation experiment,the plasmid conjugations were done for 18 times between 3 donators and 6 acceptors,7 of which gained the resistant phenotype and the transfer rate was 39%.Erythromycin-resistance was transferred from the donators to the conjugants in varying degrees.The resistance was transferred from Enterococcus faecalis to Corynebacteria and then to other Corynebacteria which were of the salne genus but of different species.Conclusion Filter mating conjugation method could be used to study the mechanisms of resistance transmission of Corynebacterium.

Objective To investigate changes of metabolic syndrome (MS ) in patients with adrenocortical adenoma (ACA ). Methods Sixty‐five patients with aldosterone producing adenoma (APA) ,43 patients with cortisol‐secreting adenoma (CSA) and 24 patients with nonfunctional adrenal adenoma (NAA) were evaluated. Body Mass Index (BMI) ,blood pressure ,plasma lipid ,fasting and 2 h postprandial plasma glucose ,plasma and urinary aldosterone ,plasma potassium ,basic and upright plasma renin activity (PRA ) ,plasma and urinary cortisol ,plasma ACTH and plasma potassium ACA were examined and compared with those from 53 patients of essential hypertension (EH ) and 58 controls. Adrenalectomy was performed for all the patients with adrenocortical adenoma. The data after operation were compared with those before operation. Results (1) The prevalence of MS was 38.5% ,41.9% , 20.8% ,24.5% and 17.5% in the groups respectively. The prevalence of obesity/overweight was higher in CSA group than in the other groups. There were 44.6% patients with hyperglycemia in APA group ,and 48.8% in CSA group. The prevalence of hypertension was the highest in APA and EH group ,followed by CSA group ,NAA and control groups. There were 55.4% patients with lipid disturbance in APA group , and 46.5% in CSA group. (2 ) We divided all APA and CSA patients into groups with or without MS. The APA patients with MS had higher plasma aldosterone than those without MS. The CSA patients with MS had higher 08 :00 and 24 :00 plasma cortisol than those without MS. (3) After operation ,the plasma and urinary aldosterone were decreased and the plasma potassium was increased in APA patients. The 08 :00 ,24 :00 plasma cortisol and urinary cortisol were decreased and the 08 :00 plasma ACTH was increased in CSA patients. There were no significant differences in hormonal measurements of NAA patients before and after operation. (4 ) The prevalence of MS was 27.7% ,27.9% and 29.2% in three groups after operation. The systolic and diastolic blood pressures were decreased in APA patients after operation ,and the systolic blood pressure decreased in CSA patients. There was no significant difference in MS measurements of NAA patients before and after operation. Conclusions Our study indicates that patients with functional adrenocortical adenoma have a significantly higher prevalence of metabolic syndrome which is related to over secretion of adrenal cortex hormone. After operation ,accompanying normalization of hormonal secretion ,the condition of MS in functional adrenocortical adenoma patients is improved.

Purpose:To investigate the status of p16 gene and its influence in p16 mRNA expression in primary hepatocellular carcinoma (HCC). Methods:The methylation status of p16 gene and expression of p16 mRNA were examined by methylation-specific PCR (MSP) and RT-PCR in twenty-five primary HCC and corresponding paracancerous tissue specimens.Results:Methylation was detected in 12 of 25 (52.0%) tumor tissue specinmens, while 6 of 25 (24.0%) in corresponding paracancerous tissue specimens. Loss of p16 mRNA expression was found in 19 specimens with methylated p16 gene,while expression of p16 mRNA was detected in 27 of 31 specimens with unmethylated p16 gene. There was significant difference in mRNA expression between specimens with methylated p16 and unmethylated p16.Conclusions:p16 gene methylation is a frequent event in HCC. The methylation of p16 gene might lead to loss of p16 mRNA expression. Detection of p16 gene methylation may be a useful marker in the molecular diagnosis of hepatocellular carcinomas.
