BackgroundThe issue of depression among adolescents is becoming increasingly serious， seriously endangering their healthy development. The issue of sleep disturbances in adolescents with depressive disorder is gradually receiving attention， but there is currently a lack of research on the relationship between sleep quality and suicide risk in this patient population. ObjectiveTo explore the relationship between suicide risk and sleep quality in adolescents with depressive disorders， and analyze the influencing factors of suicide risk， so as to provide references for clinical intervention. MethodsA total of 101 adolescents patients who met the diagnostic criteria for depressive disorder in the International Classification of Diseases， 10th edition （ICD-10） and were hospitalized at Hefei Fourth People's Hospital from June 2020 to February 2023 were selected. The patients were evaluated using the Nurses' Global Assessment of Suicide Risk （NGASR） and Pittsburgh Sleep Quality Index （PSQI）. According to the NGASR score， patients were divided into severe suicide risk group （n=35） and non-severe suicide risk group （n=66）. Pearson correlation analysis was used to examine the correlation between sleep quality and suicide risk in adolescents with depression. Multiple Logistic regression was used to analyze the influencing factors of severe suicide risk in adolescent patients with depression. ResultsStatistically significant differences were found between the two groups in terms of academic pressure， peer relationship and family relationship （t=3.942， 4.378， 6.748， P<0.05）. Moreover， there was a statistically significant difference in PSQI score between two groups （t=7.398， P<0.05）. There was also a statistically significant difference in sleep quality between the two groups （χ²=4.986， P<0.05）. Pearson correlation analysis showed a positive correlation between total PSQI score and NGASR score （r=0.698， P<0.05）. Severe depression （OR=1.628， 95% CI： 1.079~2.457）， high academic pressure （OR=1.118， 95% CI： 1.018~1.228） and poor sleep quality （OR=1.158， 95% CI： 1.033~1.297） were identified as risk factors of severe suicide risk， while good relationships with classmates （OR=0.908， 95% CI： 0.826~0.998） and family （OR=0.904， 95% CI： 0.823~0.993） were protective factors. ConclusionSleep quality in adolescents with depression is negatively correlated with suicide risk and poor sleep quality may be a risk factor for severe suicide risk.

COVID-19 has been prevalent for three years. The virulence of SARS-CoV-2 is weaken as it mutates continuously. However, elderly patients, especially those with underlying diseases, are still at high risk of developing severe infections. With the continuous study of the molecular structure and pathogenic mechanism of SARS-CoV-2, antiviral drugs for COVID-19 have been successively marketed, and these anti-SARS-CoV-2 drugs can effectively reduce the severe rate and mortality of elderly patients. This article reviews the mechanism, clinical medication regimens, drug interactions and adverse reactions of five small molecule antiviral drugs currently approved for marketing in China, so as to provide advice for the clinical rational use of anti-SARS-CoV-2 in the elderly.

Neonatal skin care is still an important aspect of newborn care. At present, although there are nursing standards for various types of neonatal skin problems, there are different reports on complete evidence-based neonatal skin care practices. The American Association of Women's Health, Obstetric and Neonatal Nurses (AWHONN) developed and published the fourth edition of the Evidence- based Clinical Practice Guideline for Neonatal Skin Care in 2018. The guideline gives detailed guidance on the assessment of neonatal skin, identification of risk of neonatal skin damage, intervention of neonatal skin care, method of promoting neonatal skin development, and treatment of neonatal skin damage. However, nurses in China know little about this guideline. In order to facilitate nurses' understanding and application of this guideline to guide clinical practice, the content of this guideline is specially interpreted.

Background The current oil production determines oil workers’ occupational noise exposure. Without effective protection, noise will affect various aspects of worker’s body functions, including acting on the adrenal cortex system and resulting in renal function damage. Objective To evaluate the associations of noise exposure and its cumulative exposure level with renal function impairment of oil workers. Methods Oil workers from a collective medical examination in a hospital were selected as the study subjects. In accordance with the national standard Measurement of Physical Agents in the Workplace Part 8: Noise (GBZ/T 189.8—2007), noise exposure was measured three times at the oil workers' work site, and their average value was calculated to obtain the cumulative noise exposure (CNE). A questionnaire survey was conducted to collect general information such as socio-demographic characteristics, family history, lifestyles, and occupational history. All blood biochemical indicators were measured in the fasting state. Renal function impairment was judged based on the glomerular filtration rate. The relationship between CNE and renal function was analyzed using receiver operating characteristic curve (ROC) for workers with noise exposure. Results A total of 2 917 subjects were included in the study and their prevalence of renal function impairment was 14.2%. The univariate analysis results suggested statistically significant differences in the prevalence of renal function impairment among the oil workers grouped by having hypertension or not, gender, age, marital status, marital status, smoking, and alcohol consumption (P＜0.05); the prevalence of renal impairment was significantly higher in those with abnormal values of uric acid, total cholesterol, triglycerides, high-density lipoprotein, and fasting glucose than in those with normal values (P＜0.05); the oil workers with noise exposure [n=1565, 53.7%, equivalent sound level ≥80 dB(A)] showed a higher prevalence of renal function impairment than those without (P＜0.05). The results of multiple logistic regression analysis showed that being female (OR=2.811, 95%CI: 1.960-4.030), age at 31 years and above (OR_31-40=3.502, 95%CI: 1.402-8.751; OR_41-50=4.255, 95%CI: 1.759-10.291; OR_≥51=7.179, 95%CI: 2.864-17.996), showing abnormal uric acid (OR=5.932, 95%CI: 4.486-7.843), having hypertension (OR=1.593, 95%CI: 1.230-2.063), alcohol consumption (OR=2.648, 95%CI: 1.346-5.212), and smoking (OR=1.816, 95%CI: 1.133-2.911) had higher risks of developing renal function impairment; besides, those exposed to noise had 1.351 times (95%CI: 1.073-1.702) higher risks of developing renal function impairment than non-exposed individuals. Noise-exposed oil workers in the renal impairment group had higher noise exposure intensity and CNE compared to the noise-exposed oil workers in the normal renal function group (P＜0.05), and the workers had an increased risk of renal function impairment when the CNE was >95.85 dB(A)·year versus CNE ≤ 95.85 dB(A)·year (OR=2.583, 95%CI: 1.956-3.411). Conclusion Exposure to noise, higher noise exposure intensity, and higher level of CNE may be associated with developing renal function impairment in oil workers. Oil workers with CNE above 95.85 dB(A)·year are at an increased risk of renal impairment.

AIM: To study the distribution of CYP2C9∗3 and VKORC1-1639G>A gene polymorphism in Han population in Anhui province and their influence on the stable dose of warfarin. METHODS: The blood samples of 1 169 patients from 6 tertiary general hospitals in 5 areas of Anhui province from January 2020 to December 2021 were selected, the genotype of CYP2C9∗3 and VKORC1-1639G>A was detected by fluorescent staining in situ hybridization technique. RESULTS: The distribution of CYP2C9∗3 genotypes in 1 169 patients: the frequencies of AA, AC and CC genes were 90.16%, 9.24% and 0.60%, respectively; The distribution of VKORC1 genotype: the frequencies of AA, AG and GG genes were 84.26%, 14.71% and 1.03% respectively; There was no significant difference between the two genotypes in gender, age and regional distribution (P>0.05). The average daily warfarin dose of CYP2C9∗3 AA genotype in 755 patients with stable warfarin dose was (3.02±0.59) mg/d, which was significantly higher than patients with AC genotype and CC genotype; The average daily warfarin dose of patients with VKORC1-1639AA genotype was (2.72±0.40) mg/d, which was significantly lower than that of patients with AG genotype and GG genotype (P<0.05). And the difference was statistically significant (P<0.05); There are significant differences in gender, age and clinical diagnosis between patients with stable dose of warfarin and those without stable dose (P<0.05). CONCLUSION: CYP2C9 and VKORC1 genotypes are associated with the stable dose of warfarin. Clinical anticoagulation therapy guided by CYP2C9 and VKORC1 genotypes can provide guidance for individualized medication of warfarin.

Objective: To understand emotional and behavioral problems of children aged 3-6 years, and to explore the role of parenting style in the development of those problems. Methods: A total of 2 278 children from 11 public kindergartens in Tongling City from April to June 2018 were selected by cluster sampling method. The questionnaire was made up by parents. The questionnaire mainly included: children, basic information of parents and children, children’s psychology and behavior, and parents’ education style, etc. Results: Among 2 278 children, 192(8.43%) had abnormal emotional symptoms, 214 (9.39%) had conduct problems, 376(16.50%) had hyperactivity problems, 537(23.57%) had peer problems, 233(10.2%) had abnormal total difficulty scores and 254(11.15%) had prosocial behaviors. Gender, age, health status of the child, second-hand smoke exposure of the baby, parents’ education level, family economic conditions, and parents’ education mode are all the influencing factors of children’s emotion and behavior(P<0.05). Logistic analysis showed that father’s support participation(OR=0.96, 95%CI=0.95-0.98), mother’s support participation (OR=0.94, 95%CI=0.92-0.95), mother’s hostility compulsion (OR=1.08, 95%CI=1.06-1.10) and 3-6-year-old children’s abnormal mood and behavior were correlated(P<0.01). Conclusion Parental support and maternal hostile are related to emotional and behavioral problems of 3-6-year-old children.
