Depression and Anxiety Mediate the Association between Sleep Quality and Self-Rated Health in Healthcare Students.

Objectives: This study aimed to investigate factors associated with sleep quality in healthcare students and to determine whether depressive and anxiety symptoms may explain some of the associations between sleep quality and self-rated health.

Study Design: This is a cross-sectional study at wave one.

Methods: A total of 637 healthcare students were recruited via a stratified random sampling method in Hangzhou, China.

Palladium-Catalyzed Alkenyl C-H Activation/Diamination toward Tetrahydrocarbazole and Analogs Using Hydroxylamines as Single-Nitrogen Sources.

A palladium-catalyzed alkenyl C-H activation/diamination reaction of cycloalkenyl bromoarenes with hydroxylamines is described. A wide range of tetrahydrocarbazoles and analogs has been prepared using fine-tuning bifunctional secondary hydroxylamines as the single-nitrogen sources. Mechanistic investigations suggest that the selective alkenyl C-H activation/diamination cascade process should build the N-heterocycles.

Periodontitis and Number of Teeth in the Risk of Coronary Heart Disease: An Updated Meta-Analysis.

BACKGROUND A positive link between periodontitis and chronic systemic disease has been indicated. However, few studies focused on the loss of teeth. Our analysis aims to analyze the relationship of periodontitis and number of teeth with the risk of coronary heart disease (CHD).

Effect of dexmedetomidine on prevention of postoperative nausea and vomiting in pediatric strabismus surgery: a randomized controlled study.

Background: Postoperative nausea and vomiting (PONV) are common side-effects following strabismus surgery. The present study aimed to compare the effects of different doses of dexmedetomidine (DEX) on PONV incidence in pediatric patients undergoing strabismus surgery.

Methods: In this prospective randomized double-blinded study, 126 pediatric patients undergoing strabismus surgery were randomized into one of three groups: Placebo group, normal saline; DEX1 group, 0.

Access to Stereodefined ()-2-Silylallylboronates via Regioselective Chloroboration of Allenylsilanes.

A catalyst-free method for the highly regioselective chloroboration of allenylsilanes is described. In the presence of BCl and 2,6-lutidine, chloroboration of allenylsilanes proceeds smoothly without any catalyst, and the product could be treated with pinacol to afford the corresponding pinacol borates in one-pot reaction. This reaction provides a direct approach to construct valuable 2-silylallylboronate frameworks with operational simplicity and high atom-economy.

Comparison of surgical field visibility during propofol or desflurane anesthesia for middle ear microsurgery.

Background: To compare surgical field visibility between patients given propofol/remifentanil (PR) or desflurane/remifentanil (DR) anesthesia.

Methods: A total of 80 adult patients undergoing middle ear microsurgery due to cholesteatoma otitis media with American Society of Anesthesiologists physical status I and II were randomly assigned to the PR or DR groups. The depth of anesthesia was titrated to maintain a Bispectral index (BIS) between 40 and 50.

Quality of recovery in patients undergoing endoscopic sinus surgery after general anesthesia: total intravenous anesthesia vs desflurane anesthesia.

Background: For sinus surgery, some centers favor total intravenous anesthesia (TIVA) over inhalation anesthesia. However, whether TIVA affects the patient's perceived quality of recovery remains unclear. This study used the Quality of Recovery-40 questionnaire (QoR-40) to compare patient recovery between surgical patients who received TIVA and those who received desflurane (DES) anesthesia.

Dexmedetomidine in combination with sufentanil for postoperative analgesia after partial laryngectomy.

Background: Dexmedetomidine as an adjunct with opioids has been confirmed to spare opioids usage and improve analgesia for postoperative pain treatment. Furthermore, dexmedetomidine can attenuate the airway reflex. The aim of this study is to assess the safety and efficacy of dexmedetomidine combined with sufentanil for postoperative analgesia after partial laryngectomy.

Effects of a Single Dose Dexmedetomidine on Surgical Field Visibility During Middle Ear Microsurgery: A Randomized Study.

Objectives: To investigate whether a single dose of dexmedetomidine (DEX) improves surgical field visibility.

Study Design: Randomized, prospective, double-blind study.

Setting: Tertiary teaching hospital.

Cellular MicroRNA Let-7a Suppresses KSHV Replication through Targeting MAP4K4 Signaling Pathways.

Background: Kaposi's sarcoma (KS)-associated herpesvirus (KSHV) is the etiologic agent of KS, the most common AIDS-related malignancy. The majority of KS tumor cells harbor latent KSHV virus but only a small percentage undergoes spontaneous lytic replication. Viral reactivation from latency is crucial for the pathogenesis and development of KS, but the cellular mechanisms underlying the switch between viral latency and replication are not well understood.

[Analysis on the relations between levels of change and the mental decisive factors on the physical exercise behavior among middle school students].

Objective: To study the situation of sports and its influencing factors among students in order to improve health related education and promotion programs.

Methods: A multistage random sampling method was used on 3 600 students from three cities to understand their physical exercise behavior. Both t and χ(2) test were used to measure the scale of psychology and to describe the time spent on exercise.

[The adolescent physical exercise behavior-psychological measurement scale on the Chinese version and its reliability and validity study].

Objective: To develop a suitable physical exercise behavior-psychological scale for the Chinese adolescents and to evaluate its validity and reliability.

Methods: A total of 3600 junior students were recruited and tested through multistage sampling method. Reliability was assessed, using Cronbach's α and split-half reliability; while exploratory factor analysis and confirmatory factor analysis were used to test its validity, with entries-dimension correlation coefficient (IIC), correlation coefficient between the scores and the dimension, the dimension of correlation coefficient test content validity.

Comparison of the effects of dexmedetomidine, ketamine, and placebo on emergence agitation after strabismus surgery in children.

Background: Children undergoing strabismus surgery under sevoflurane anesthesia often experience emergence agitation (EA) and postoperative vomiting (POV). This study compared the effects of intraoperative dexmedetomidine, ketamine, and placebo on postoperative EA and POV.

Methods: Eighty-four children (aged two to seven years) undergoing elective strabismus surgery under sevoflurane anesthesia were randomly assigned to one of three groups (n = 28 each).

Assessment of fruit and vegetable intake behavior among adolescents in Hangzhou, China.

Objective: To evaluate the fruit and vegetable (FV) intake of adolescents, assess factors influencing intake and discuss health education strategies related to this behavior.

Methods: In Hangzhou, China, 861 students aged 13.68 ± 1.

[Evaluation on the effects of an education program regarding the sedentary behavior among school-aged children using Transtheoretical Model].

Objective: To evaluate the outcome of a health education program on sedentary behavior among primary and secondary school children through Transtheoretical Model.

Methods: Five primary schools and four middle schools were selected and students from grade 3 to 5 in primary schools and grade 1 to 2 in middle schools were selected to take part in the program, as control and intervention groups respectively. Corresponding intervention measures were provided to the intervention group, with phase, process and level of changing on sedentary behavior measured for both groups during the follow-up period.

[A cross-sectional study on the changes in dietary behavior stages in resident].

Objective: To explore the possibility of applying the concept of various stages of dietary behavior changes in Hangzhou residents.

Methods: The dietary behavior was surveyed and analyzed in 1 388 Hangzhou residents with 18 year-old and older using the various dietary behavior change model model and stages of change.

Results: The proportion of Hangzhou residents with unhealthy dietary behavior was high and associated with gender and education level.
