Background The first year of attending university induces a stressful experience for many college students. The experience exposes these students to challenging circumstances and raises expectations, which consequently increases the risk of psychiatric disorders and may exacerbate pre-existing problems. This study was designed to explore the risk factors of psychological symptoms among freshmen in China. Methods A three-year follow-up study was designed in a sample of Chinese college freshmen. To set up the baseline interviews, subjects from 25 high schools in Beijing were interviewed during the first year in high school. Three years later, we followed up with the 1547 students from 15 of the previously-selected 25 high schools after they had entered universities. Association between potential risk factors and the occurrence of psychological symptoms measured by the Symptoms Check List-90 was evaluated in unconditional logistic regression models with Wald test. Results Among the 1547 interviewed college freshmen in the study, 120 students （7.8%） manifested at least one psychological symptom. Personality dysfunction （OR=3.655, 95% CI 1.967-6.793）, parental rejection （OR=2.619, 95% CI 1.544-4.442）, age 〉 20 （OR=2.578, 95% CI 1.227-5.418）, disfavored university （OR=2.054, 95% CI 1.376-3.066）, non- first-choice academic major （OR=1.887, 95% CI 1.255-2.837） and no orientation （OR=1.739, 95% CI 1.025-2.951） were determined to be the risk factors of psychological symptoms among the college freshmen in China. Conclusions Psychological symptoms of college freshmen are associated with personality traits, parental rearing behavior and study environment. Therefore, it is important to pay attention to changes in mental health as students enter or decide on colleges and increase education geared towards mental health issues for students in high school and universities in China.

To summarize the advances in antibiotic therapy for infection after the surgical installation of implants to treat internal fractures. Recent studies on antibiotic therapy for infection after the surgical installation of implants to internal fractures were reviewed and *** general, systematic antibiotics are selected based on the results of bacterial culture. The duration of antibiotic treatment lasts for no more than 4 to 6 weeks. Orally administered and intravenously injected antibiotics have similar efficacies. Orally administered antibiotics exhibit a lower incidence of complications and are less costly than intravenously injected antibiotics. In addition, the efficacy of daptomycin in the treatment of bone infection is problematic. Rifampicin or fluoroquinolone antibiotics should be jointly administered when infection with bacterial biofilms is likely to occur. Calcium sulfate is a typical topically applied antibiotic delivery vehicle that can be completely degraded, with good biocompatibility, bone conduction, and drug release. The rational, systematic, and combined topical application of antibiotics can effectively decrease the recurrence rates of infection after the surgical installation of implants to treat internal fractures and can improve the quality of life of patients.

该文研究了多相码雷达信号的识别与参数估计。首先估计接收信号的码元宽度,利用多相码信号的时宽和码元宽度已知的条件下可以确定相位调制规律的特点,构造本地参考信号;把该参考信号与接收信号共轭相乘,当本地参考信号与接收信号的调制方式一致时共轭相乘的结果是正弦波,利用这个性质进行调制方式识别;估计该正弦波的频率作为载频估计;最后分析了存在同步误差时的频谱结构。仿真结果显示本算法可以在低信噪比条件下对多相码信号进行识别,并得到载频和码元宽度的精确估计值。
