Objective To detect the antibiotic resistance of four kinds of gram-negative bacilli strains against seven antibiotics and to analyze the differences in antibiotic resistance between the strains isolated in intensive care unit (ICU) and common wards.Methods This study involved 3 238 gram-negative bacilli strains isolated in Beijing Tongren Hospital from January to December 2016.Of all strains, 46.6% were isolated in ICU (severe group) and 53.4% were isolated in common wards (general group).Resistance of these strains to seven kinds of antibiotics was detected and the differences between the two groups were analyzed.Results Antibiotic resistance rates of Pseudomonas aeruginosa strains to ceftriaxone, cefepime and imipenem were 41.7%, 41.2% and 39.5% in severe group and 20.9%, 21.7% and 17.1% in general group.Moreover, the differences between the two groups were all statistically significant (χ2Cefatriaxone=56.72, P<0.01;χ2Cefepime=49.12, P<0.01;χ2Imipenem=69.81, P<0.01).Antibiotic resistance rates of Klebsiella pneumoniae strains to imipenem was 17.2% in severe group and 8.8% in general group, and the difference between the two groups was statistically significant (χ2Imipenem=11.48, P<0.01).Resistance rates of Escherichia coli strains to ceftriaxone and cefepime were 72.9% and 35.8% in severe group and 44.7% and 13.3% in general group, and the differences between the two groups were statistically significant (χ2Ceftriaxone=40.13, P<0.01;χ2Cefepime=41.61, P<0.01).More than 60% of Acinetobacter baumanii strains whether they were isolated in ICU or in common wards were resistant to all the seven antibiotics, and there were no significant differences between the two groups.Conclusion Gram-negative bacilli strains isolated in ICU have higher resistance rates than those isolated in common wards and therefore antibiotics should be used differently.Regular monitoring of drug resistance should be strengthened to provide references for empirical clinical medication.

Objective To observe the effect of acupoint thread-embedding at Neiguan (PC6) and Zusanli (ST36) on anxiety and sleep disorders after heroin withdrawal. Method Sixty-seven patients with heroin addiction were randomized into a Neiguan group (25 cases), a Zusanli group (22 cases) and a Neiguan plus Zusanli group (20 cases), to receive corresponding treatments once every 20 d, for 4 sessions in total. The Self-rating Anxiety Scale (SAS) and Pittsburgh Sleep Quality Index (PSQI) were adopted to observe the anxiety and sleep condition before and after the treatment. Result After 60 d thread-embedding treatment, the total and standard SAS scores, sleep initiation time and total PSQI score were significantly decreased in the 3 groups (P<0.05), and the sleep durations were significantly extended (P<0.05); in comparing the improvement of anxiety, Neiguan plus Zusanli group > Neiguan group >Zusanli group (P<0.05); in comparing the improvement of sleep, Neiguan plus Zusanli group was superior to both Zusanli group and Neiguan group (P<0.05), while there was no significant difference between Zusanli group and Neiguan group (P>0.05). Conclusion It's effective to use thread-embedding at Neiguan and Zusanli independently or together for anxiety and sleep disorders after heroin withdrawal, but the efficacy is more significant when the two points are used in combination, indicating the synergy of acupoints.

There were some shortcomings for traditional teaching mode of nutrition and food hygiene course, such as many teaching contents and little teaching time, students much passively learning and little active learning. We explored the combination of the WeChat and the TBL teaching to conduct the flipped classroom to solve the deficiency. The teaching pattern was conducted in 60 students majoring in preventive medicine from Grade 2012. The learning task of nutrition and food hygiene was released on the WeChat before the class. Students learned knowledge in the form of discussion based on case in the class. After the class, the discussion, answer the question and test were conducted on the WeChat. The survey showed that 85% of the students were satisfied with teaching pattern,especially satisfied with its role of broadening students' knowledge and vision, improving their autonomous learning ability, teamwork ability, and their ability to analyze and solve problems.
