ABSTRACT
Objective@#This cross-sectional study explores the serial multiple mediation of the correlation between internet addiction and depression by social support and sleep quality of college students during the COVID-19 epidemic. @*Methods@#We enrolled 2,688 students from a certain university in Wuhu, China. Questionnaire measures of internet addiction, social support, sleep quality, depression and background characteristics were obtained. @*Results@#The prevalence of depression, among 2,688 college students (median age [IQR]=20.49 [20.0, 21.0] years) was 30.6%. 32.4% of the students had the tendency of internet addiction, among which the proportion of mild, moderate and severe were 29.8%, 2.5% and 0.1%, respectively. In our normal internet users and internet addiction group, the incidence of depression was 22.6% and 47.2%, respectively. The findings indicated that internet addiction was directly related to college students’ depression and indirectly predicted students’ depression via the mediator of social support and sleep quality. The mediation effect of social support and sleep quality on the pathway from internet addiction to depression was 41.97% (direct effect: standardized estimate=0.177; total indirect effect: standardized estimate= 0.128). The proposed model fit the data well. @*Conclusion@#Social support and sleep quality may continuously mediate the link between internet addiction and depression. Therefore, the stronger the degree of internet addiction, the lower the individual’s sense of social support and the worse the quality of sleep, which will ultimately the higher the degree of depression. We recommend strengthening monitoring of internet use during the COVID-19 epidemic, increasing social support and improving sleep quality, so as to reduce the risk of depression for college students.
ABSTRACT
Objective@#To analyze the current situation of the knowledge, attitudes and practice about Novelcoronavirus pneumonia (NCP) of the residents in Anhui Province. @*Methods@#Anonymous network sampling survey was carried out with an electronic questionnaire that designed by the questionnaire star, and a total of 4016 subjects from Anhui province were investigated. The content of the survey includes that the basic information of subjects,the residents’ knowledge, attitudes and practice about NCP, as well as their satisfaction with the prevention and control measures adopted by the government and health authorities and the suggestions on future prevention. The questionnaire doesn’t involve any privacy information, and all questions were mandatory to ensure the response rate.@*Results@#The M (P25, P75) age the 4016 subjects was 21 (19, 24), and the ranging from 7 to 80 years old. The number of males was1431(35.6%). Social networking tools such as WeChat and QQ were the main sources of epidemic information for residents (97.8%, 3 929 respondents). Residents have a high awareness rate of the main symptoms, transmission routes, using of masks, hand washing and treatment information of NCP, while a low awareness rate of the atypical symptoms. 92.6% of the subjects (n=3 720) think that the outbreak was scary. In terms of psychological behavior scores, the results showed that female (9.38±4.81), the urban (9.37±5.02) and the medical workers (10.79±5.19) had a poorer mental health than the male (8.45±5.00) , the rural (8.71±4.75) and the non-medical workers (the students: 8.85±4.83; public institude workers: 9.02±5.08; others: 8.97±5.39) (P < 0.05). 71.9% of the residents (n=2 887)were satisfied with the local epidemic control measures. The residents took various of the measures to prevent and control the epidemic. The ratio of residents that could achieve "no gathering and less going out" , "wear masks when going out" and "do not go to crowded and closed places" was up to 97.4% (n=3 913), 93.6% (n=3758) and 91.5% (n=3 673) respectively.@*Conclusion@#The residents in Anhui province have a good KAP about NCP, yet it is necessary to strengthen the community publicity, the mental health maintenance of residents and students’ health education.
ABSTRACT
Objective@#The purpose of this cross-sectional survey is to explore the current state of Internet addiction (IA) in Chinese medical students and its connection with medical students’ sleep quality and self-injury behavior. @*Methods@#Respondents were came from Wannan Medical College, China. The Young’s Internet Addiction Test, Pittsburgh Sleep Quality Index (PSQI), Self-Harm Questionnaire were used in this cross-sectional survey. A total of 3,738 medical students were investigated, 1,552 (41.52%) males, 2,186 (58.48%) females. T-test, chi-square test and MANOVA were used for data analysis. @*Results@#Of the 3,738 medical students, 1,054 (28.2%) reported having IA, 1,126 (30.1%) reported having poor sleep quality, 563 (15.1%) having self-harm behaviors. IA tends to be more female, upper grade students. The sleep quality of IA was worse than that of non-IA (χ2=54.882, p<0.001), and the possibility of self-injury was higher than non-IA (χ2=107.990, p<0.001). @*Conclusion@#This survey shows that the IA detection rate of medical students was 28.2%. Females, higher grade students had a higher IA detection rate. The low sleep quality and self-injury behavior of medical students are associated with IA.

<p><b>BACKGROUND</b>Bilateral transpedicular screw fixation in conjunction with interbody fusion is widely used to treat lumbar degenerative diseases; however, there are some disadvantages of using this fixation system. This study comparatively analyzes the results of unilateral and bilateral pedicle screw fixation combined with transforaminal lumbar interbody fusion (TLIF) for one-level lumbar degenerative diseases.</p><p><b>METHODS</b>Sixty-six cases with one-level lumbar degenerative diseases were studied. The patients were divided according to surgical approach into a unilateral group (Group A) and a bilateral group (Group B). The patients were evaluated for pain by visual analog scale (VAS) and Oswestry Disability Index (ODI). Operating time, blood loss, duration of hospitalization, and complication rate were also evaluated. Patients were examined at 1, 3, 6, and 12 months postoperatively and every year thereafter.</p><p><b>RESULTS</b>Group A patients' average preoperative VAS and ODI scores were 7.03 ± 0.98 and (64.22 ± 6.38)%, respectively, significantly decreased to 2.91 ± 0.88 and (14.42±2.08)%, respectively, at the last follow-up (P = 0.000). In Group B, the average preoperative VAS and ODI scores were 6.79 ± 0.86 and (63.22 ± 4.70)%, respectively, significantly decreased to 3.12 ± 0.96 and (14.62 ± 2.08)%, respectively, at the last follow-up (P = 0.000). No significant difference in the duration of hospitalization was found between groups. Operating time and blood loss of (125.9 ± 13.0) minutes and (211.4 ± 28.3) ml, respectively, in Group A were significantly less than (165.2 ± 15.3) minutes and (258.6 ± 18.3) ml, respectively, in Group B (P = 0.000). All patients achieved good bone union and had no pseudarthrosis at the last follow-up.</p><p><b>CONCLUSIONS</b>There are no clinical differences between unilateral and bilateral pedicle screw fixation combined with TLIF for one-level lumbar degenerative diseases. Unilateral fixation reduces operating time, bleeding, and cost of hospitalization.</p>

Objective To evaluate the application effect of‘incorrect cases’in medical statis-tics teaching. Methods The junior students (n=307)of clinical medicine were selected as research subjects by random cluster sampling. They were divided into the teaching improving group (n=151) who accepted case teaching and control group (n=156)who accepted traditional teaching. At the end of the term,the teaching effect was surveyed by questionnaires and compared between the two groups. Measurement data was analyzed by t test,enumeration data by χ2 test and ranked data by rank sum test. Results Students' interests of medical statistics and understanding the importance of the course in teaching improving group were significantly higher than that in control group (Z=-2.375,P=0.018;Z=-2.971,P=0.003). The proportion of students with learning difficulties in teaching improving group was obviously lower than that in control group (Z=-2.488,P=0.013). The satisfaction with theory and practical teaching in teaching improving group (84.10% and 88.74%,respectively)was significantly higher that in control group (73.08%and 71.79%,respectively)(χ2=5.530,P=0.013;χ2=13.841,P<0.001). Although no difference was observed in the test score between the two groups (t=1.230,P=0.220),knowledge of parameter estimation,hypothesis testing and science research design in teach-ing improving group was significantly higher than that in control group (χ2=6.829,P=0.009;χ2=5.835, P=0.016). Conclusions Application of ‘incorrect cases’in medical statistics teaching could arouse students' learning interests and improve clinical medical students' comprehensive analy sis ability of medical statistics.
