Objective:
To study the current situation of sleep quality of senior high school students and analyze the influencing factors, so as to provide a reference for targeted sleep quality improvement of high school students.
Methods:
A total of 4 793 senior high school students of different grades were recruited from four different regions (Shanghai, Qinghai, Macao, Henan) in 2020. The information of demographic, sleep status, mental factors, living habits and other information were collected by questionnaire. Descriptive statistics and Logistic regression were used to analyze sleep quality and its influencing factors of the senior high school students.
Results:
About 24.2% of senior high school students reported sleep problems and 71.4% slept less than 7 hours at night. Interpersonal sensitivity, depression, anxiety symptoms, learning, family and interpersonal stress had significant effects on sleep problems in senior high school students( χ 2=1 147.98, 1 228.35, 1 032.54, 371.05, 497.61, 475.39, P <0.01). Drinking coffee and tea, drinking alcohol, smoking (including secondhand smoke), long term use of electronic products, late sleep, bedtime diet, poor sleep environment, parents with sleep problems were the risk factors for sleep disorders of senior high school students, regular exercise was the protective factors for sleep disorders of senior high school students, the influence was significant ( χ 2=160.28, 127.73 , 108.02, 113.27, 470.91, 340.95, 72.02, 155.53, 116.30, 76.96, 28.75, 12.89, P <0.05).
Conclusion
The sleep quality of senior high school students needs to be improved. Schools and parents should pay attention to the mental health and living habits of senior high school students to help them improve their sleep quality and grow up smoothly.

PURPOSE: The aim of this research was to assess the value of the transitional zone index (TZI) and intravesical prostatic protrusion (IPP) from transrectal ultrasonography in evaluating the severity and progression of disease by analyzing the relationship between the 2 parameters and symptoms, clinical history, and urodynamics in benign prostatic hyperplasia (BPH) patients undergoing different treatment. MATERIALS AND METHODS: A total of 203 patients receiving medication and 162 patients who underwent transurethral resection of the prostate because of BPH were enrolled in this retrospective analysis. The clinical history and subjective and objective examination results of all patients were recorded and compared after being classified by TZI and IPP level. Linear regression was used to find correlations between IPP, TZI, and urodynamics. RESULTS: The 2 parameters were found to differ significantly between patients receiving medication and patients undergoing surgical therapy (p<0.05). PSA, maximum flow rate (Qmax), detrusor pressure at Qmax (PdetQmax), and the bladder outlet obstruction index (BOOI) differed according to various TZI levels (p<0.05). In addition, the voiding symptom score, Qmax, and BOOI of subgroups with various IPP levels were also significantly different (p<0.05). Both TZI and IPP had significant effects on Qmax, BOOI, and PdetQmax (p<0.05) and the incidence of acute urinary retention (p=0.000). CONCLUSIONS: The results demonstrated that both TZI and IPP had favorable value for assessing severity and progression in patients with BPH. Further studies are needed to confirm whether the two parameters have predictive value in the efficacy of BPH treatment and could be considered as factors in the selection of therapy.

Objective: To compare the mutation status of epidermal growth factor receptor (EGFR) between different lesions and clini-cal characteristics of synchronous multiple ground-glass nodules (SMGGNs). Methods: A retrospective analysis was conducted using clinical data from 35 patients with SMGGNs who were admitted to and received surgery at The Fourth Hospital of Hebei Medical Uni-versity Hospital from January 2017 to December 2018. Next generation sequencing (NGS) was performed for all surgical specimens to detect the mutation status of exons 18, 19, 20, and 21 of the EGFR gene to analyze the relationship between the EGFR mutation sta-tus of the lesions and patient gender, age, lesion location, imaging manifestation of nodules, and adenocarcinoma pathological type . Results: The EGFR mutation rate was 65.7% (23/35 patients). Non-smoking patients and females had higher EGFR mutation rates (P=0.015, P<0.001). The EGFR mutation rate of invasive adenocarcinoma nodules was higher than those of atypical adenomatous hyper-plasia, adenocarcinoma in situ, and minimally invasive adenocarcinoma ( P<0.001). Exon 19 deletion and L858R mutation were the most common mutations of the EGFR gene. There was no significant difference between the pathological subtypes of adenocarcino-ma and the EGFR mutant subtype (P=0.707). Among the 27 patients with multiple nodules with detectable EGFR mutations, the EGFR mutation rate was 85.2% (23/27 patients). Conclusions: The EGFR gene mutation status is different in patients with multiple pulmo-nary ground-glass nodules, suggesting that the occurrence and development of each nodule are independent events. EGFR gene muta-tion is closely related to the development of ground-glass nodules, especially in the invasion of tumors.

Community-acquired respiratory infection is the commonest cause of sepsis presenting to emergency departments. Yet current experimental animal models simulate peritoneal sepsis with intraperitoneal (I.P.) injection of lipopolysaccharide (LPS) as the predominant route. We aimed to compare the progression of organ injury between I.P. LPS and intranasal (I.N.) LPS in order to establish a better endotoxemia murine model of respiratory sepsis. Eight weeks old male BALB/c mice received LPS-Escherichia coli doses at 0.15, 1, 10, 20, 40 and 100 mg per kg body weight (e.g. LPS-10 is a dose of 10 mg/kg body weight). Disease severity was monitored by a modified Mouse Clinical Assessment Score for Sepsis (M-CASS; range 0–21). A M-CASS score ≥ 10 or a weight reduction of ≥ 20%, was used as a criterion for euthanasia. The primary outcome was the survival rate (either no death or no need for euthanasia). The progression of disease was specified as M-CASS, body weight, blood glucose, histopathological changes to lung, liver, spleen, kidney, brain and heart tissues. Survival rate in I.P. LPS-20 mice was 0% (2/3 died; 1/3 euthanized with M-CASS > 10) at 24 h. Survival rate in all doses of I.N. LPS was 100% (20/20; 3–4 per group) at 96 h. 24 h mean M-CASS post-I.P. LPS-10 was 6.4/21 significantly higher than I.N. LPS-10 of 1.7/21 (Unpaired t test, P < 0.05). Organ injury was present at 96 h in the I.P. LPS-10 group: lung (3/3; 100%), spleen (3/3; 100%) and liver (1/3; 33%). At 24 h in the I.P. LPS-20 group, kidney injury was observed in the euthanized mouse. At 96 h in the post-I.N. LPS-20 group, only lung injury was observed in 2/3 (67%) mice (Kruskal-Wallis test with Dunn’s, P < 0.01). At 24 h in the post-I.N. LPS-100 group all (4/4) mice had evidence of lung injury. Variable doses of I.N. LPS in mice produced lung injury but did not produce sepsis. Higher doses of I.P. LPS induced multi-organ injury but not respiratory sepsis. Lethal models of respiratory virus, e.g., influenza A, might provide alternative avenues that can be explored in future research.
