ABSTRACT
Objective To investigate the distribution and drug resistance of pathogens in elderly patients with gastric cancer complicated with diabetes mellitus.Methods 367 elderly patients with gastric cancer and diabetes mellitus were selected from the hospital from March 2010 to March 2017.The samples were isolated and cultured.The Gram positive bacteria were tested by GN201,the Gram negative bacteria susceptibility test was carried out by GP,and the drug susceptibility test was carried out by disk diffusion method.Results There were 68 cases of postoperative infection in gastric cancer patients with diabetes mellitus,and 79 strains were isolated and cultured.Among the gram negative bacteria,Escherichia coli,Klebsiella pneumoniae and Pseudomonas aeruginosa were the main pathogens.Among the Gram positive bacteria,Staphylococcus aureus and Staphylococcus epidermidis were the main pathogens.The main Gram negative bacteria,Escherichia coli to ceftazidime with levofloxacin resistance rates were 93.33% and 80.00%;Klebsiella pneumoniae had a higher drug resistance rate for cefoperazone and ciprofloxacin,76.92% and 69.23% respectively;a relatively high rate of Pseudomonas aeruginosa resistant to levofloxacin was 80.00%.Among the gram positive bacteria,the re-sistance rates of Staphylococcus aureus to penicillin and erythromycin were relatively high,respectively 91. 67% and 83.33%.Staphylococcus epidermidis had relatively high resistance rates to penicillin and erythromy-cin,100.00% and 77.78% respectively.Conclusion Gastric cancer complicated by diabetes mellitus elderly patients with postoperative infection of pathogenic bacteria distribution is given priority to with Gram-negative bacteria was the most common in,Pseudomonas aeruginosa,the main pathogenic bacteria of Escherichia coli to ceftazidime with levofloxacin resistant rate of Klebsiella pneumoniae was higher on cefoperazone and ciproflox-acin resistant Pseudomonas aeruginosa,the resistance rate of Pseudomonas aeruginosa to levofloxacin is high, and it is important to apply antibiotics rationally according to drug sensitivity test.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the efficacy of prevention programs and relevant factors targeting mother-to-infant transmission of HBV in Yunnan province.</p><p><b>METHODS</b>In Yunnan province, we selected HBsAg positive pregnant women that delivered in hospital from January 1st through June 30th, 2011. Newborns of these pregnant women were under PMTCT (prevention of mother to child treatment) program and followed. Every infant was drawn 2 ml venous blood and questionnaire survey was carried out when the baby was 7-12 month-old and completed the vaccination processes. Serum samples of them were then collected and detected on the 5 serological indicators of HBV.</p><p><b>RESULTS</b>were analyzed statistically.</p><p><b>RESULTS</b>There were 2 765 infants in the study program. The success rate of PMTCT was 95.88% . Rates of coverage on both timely-birth dose and 3 doses of HepB were 97.03% and 92.30% respectively. The overall vaccinated rate and timely-birth vaccinated rate on hepatitis B immunoglobulin (HBIG) were 68.97% and 94.49% respectively. The success rate of PMTCT was 97.16% after administration of passive-active immune-prophylaxis (HepB and HBIG), compared to the rate as 93.01% when vaccinated with HepB only. Significant differences were seen in the successful rates of PMTCT between combined and non-combined immunization. Either the combined or non-combined immunization, there were significant differences seen in the success rates of PMTCT regardless the positivity status of HBsAg or HBeAg, among the infected mothers.</p><p><b>CONCLUSION</b>The efficacy of passive-active immune-prophylaxis program seemed to be better than the one without combined immunization. It was vitally important for the infants whose mothers' HBsAg and HBeAg status were positive, to receive regular and timely combined immunization. In order to promote the PMTCT in Yunnan province, vaccinated rate on HBIG should be further improved.</p>
