Aromatic Chinese medicinal essential oils are volatile oils extracted from aromatic Chinese herbs， which can prevent and treat respiratory infectious diseases through multiple synergistic mechanisms including pathogen inhibition， immune regulation， and inflammatory response regulation. Essential oils are primarily used externally on the body to prevent infections and alleviate symptoms through methods like inhalation， smearing， topical application， bathing， gargling or as a suppository. They can also be utilized in the environment for disinfection and air purification， through methods like diffusion， vaporization， or spraying. The external application of essential oils extracted from Chinese aromatic herbs has the advantages of convenience， quick absorption， and simultaneous influence on both the body and mind. However， there are still challenges and deficiencies in aspects such as the positioning of functions， indications， safety， and the research on the mechanism of action. It has been proposed to combine the theory of aromatic Chinese medicinals with the characteristics of essential oils， and formulate prescriptions of Chinese medicinal essential oils under the principles of traditional Chinese medicine syndrome differentiation， and prevent and treat respiratory infectious diseases efficiently， accurately， and safely， thereby expanding the clinical application of aromatic Chinese medicinals and the preventive theory of traditional Chinese medicine.

ObjectiveTo explore the impact of autonomic nerve function on motor function in patients with post-stroke depression (PSD) from the perspective of regional homogeneity (ReHo). MethodsFrom January to December, 2020, a total of 60 inpatients and outpatients with cerebral infarction in the Affiliated Brain Hospital of Nanjing Medical University were divided into control group (n = 30) and PSD group (n = 30). Two groups were assessed using Fugl-Meyer Assessment (FMA), modified Barthel Index (MBI) and Hamilton Depression Scale (HAMD). Heart rate variability (HRV) was measured. Ten patients in each group were selected randomly to undergo resting state functional magnetic resonance imaging (rs-fMRI) to calculate ReHo. ResultsAll HRV indices were lower in PSD group than in the control group (|t| > 2.092, P < 0.05). In PSD group, FMA and MBI scores showed positive correlations with 24-hour standard deviation of normal-to-normal R-R intervals (SDNN), the root mean square of successive differences between normal heartbeats over 24 hours (RMSSD), the percentage of differences between adjacent normal R-R intervals over 24 hours that were greater than 50 ms (PNN50), total power (TP), very low frequency power (VLF) and low frequency power (LF) (r > 0.394, P < 0.05), and showed negative correlations with HAMD scores (|r| > 0.919, P < 0.001). HAMD scores in PSD group were negatively correlated with SDNN, RMSSD, PNN50, TP and VLF (|r| > 0.769, P < 0.001). Compared with the control group, the ReHo increased in PSD group in the right rectus gyrus (142 voxels, t = 6.575), the left medial and paracingulate gyri (204 voxels, t = 4.925) (GRF correction, P_-Voxel < 0.005，P_-Cluster < 0.05); and reduced in the right cerebellum (191 voxels, t = -6.487), the left middle temporal gyrus (140 voxels, t = -5.516), and the left precentral gyrus (119 voxels, t = -4.764) (GRF correction, P_-Voxel < 0.005，P_-Cluster < 0.05) in PSD group. ConclusionAutonomic nerve function is related to motor dysfunction in patients with PSD. The modulation of emotional, cognitive and motor brain regions by the autonomic nervous system may play a role in influencing the motor function in patients with PSD.

ObjectiveTo investigate the association of the polymorphisms of the acetyl-CoA acetyltransferase 1 （ACAT1） gene and the melatonin receptor 1B （MTNR1B） gene with the susceptibility to nonalcoholic fatty liver disease （NAFLD）. MethodsA total of 164 healthy controls and 228 NAFLD patients were enrolled in this study. PCR and sequencing methods were used to determine the genotypes of the polymorphisms of the ACAT1 gene at the rs1044925 and rs1157651 loci and the MTNR1B gene at the rs10830963 locus， and fasting venous blood samples were collected for biochemical analysis. The t-test was used for comparison of normally distributed continuous data between groups， and the non-parametric Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups； the chi-square test was used for comparison of categorical data between groups. ResultsThere were no significant differences between the NAFLD group and the healthy control group in the genotype distribution of the ACAT1 gene at the rs1044925 and rs1157651 loci and the MTNR1B gene at the rs10830963 locus （all P>0.05）. The carriers of AA genotype at the rs1044925 locus of the ACAT1 gene had a significantly higher level of low-density lipoprotein than the carriers of C allele （Z=-2.08， P=0.04）， and the carriers of G allele at the rs10830963 locus of the MTNR1B gene had a significantly higher level of fasting blood glucose than the carriers of CC genotype （Z=-3.01， P<0.01）. ConclusionThe polymorphisms of the ACAT1 gene at the rs1044925 and rs1157651 loci and the MTNR1B gene at the rs10830963 locus were not associated with the susceptibility to NAFLD. The rs1044925 locus of the ACAT1 gene and the rs10830963 locus of the MTNR1B gene are associated with the levels of low-density lipoprotein and fasting blood glucose， respectively.

{L-End}Objective To estimate the number of workers with occupational noise-induced hearing loss (ONHL) in the manufacturing industry of China in 2020. {L-End}Methods Multiple data sources were integrated to collect information on workers in the manufacturing industry from the Occupational Diseases and Hazards Monitoring Information System under China Disease Prevention and Control Information System. The total number of workers was split based on age from the 2018 Fourth National Economic Census and the 2020 National Survey of Occupational Disease Hazards. Additionally, data on the prevalence of hearing loss in the general population was adjusted based on the age composition of Jilin Province, and noise prevalence was standardized based on the age composition of the employed population in the Seventh National Population Censu. Attribution fractions (AF) was estimated. The prevalence ratio (PR) was calculated by the prevalence of hearing loss in the occupational noise-exposed workers and general population. The proportion and attributable cases (AC) of ONHL cases in all hearing loss cases were estimated for occupational noise-exposed workers. The number of ONHL was estimated based on AF and the total number of workers with hearing loss. {L-End}Results In 2020, a total of 30 059 525 workers were exposed to occupational noise in the manufacturing industry in China, with noise-exposed prevalence and standardized noise-exposed prevalence of 28.94% and 28.52%, respectively. The prevalence of hearing loss among occupational noise-exposed workers increased with age, and a total of 8 054 789 workers suffered from hearing loss. Most of the cases were at the age between 45-<55 years old. The total PR and 95% uncertainty interval (UI) was 2.83 (2.58-3.06) and the total AF and 95%UI was 64.63% (61.22%-67.30%), and both peaks were in the age of 30-<45 years. The AC and 95%UI was 5 205 980 (4 930 620-5 420 345) persons, and most of the cases were at the age between 40-<55 years. {L-End}Conclusion Occupational noise poses a serious threat to the hearing health of workers in the manufacturing industry of China, especially among middle-aged and young adults.

Objective:To assess the efficacy of different non-drug smoking cessation interventions on smoking cessation among the high-risk populations of lung cancer screening by network meta-analysis.Methods:PubMed, MEDLINE (Ovid), PsychINFO, CNKI, WanFang and VIP databases were searched for randomized controlled clinical trials published from January 2010 to September 2020.According to the eligibility criteria, the retrieval literature was screened, the quality evaluation and data extraction were conducted, then, the statistical analysis was performed by using the Stata 14.0 software.Results:A total of 28 trials were included, including 34 640 cases of high-risk population, involving intervention measures, including 5R short quit smoking intervention, cognitive behavior therapy, award model quit smoking intervention, motivational interview, network intervention, telephone intervention, incentive mechanism plus telephone intervention, network plus telephone intervention, conventional treatment and blank group.The results of network meta-analysis showed that on the 7-day follow-up of 6 months, according to the score of SUCRA, the ranking of smoking cessation rate was 5R short smoking cessation intervention (0.88), cognitive behavior therapy (0.85), AWARD model smoking cessation intervention (0.80), incentive mechanism plus telephone intervention (0.73), motivational interview (0.53), Internet plus telephone intervention (0.40), Internet intervention (0.37), telephone intervention (0.31), conventional treatment (0.13) and blank group (0.03). However, on the 7-day smoking cessation rate of 12-month follow-up, the ranking of smoking cessation rate was 5R short smoking cessation intervention (0.94), AWARD model smoking cessation intervention (0.81), motivational interview (0.51), network intervention (0.40), telephone intervention (0.19) and conventional treatment (0.14).Conclusions:The existing evidence shows that no matter the length of follow-up, 5R short smoking cessation intervention has the best effect on smoking cessation in high-risk population of lung cancer screening.

Objective:To evaluate the role of spinal Rac1 signaling pathway in the maintenance of bone cancer pain (BCP) in rats.Methods:Sixty-four clean-grade adult female Sprague-Dawley rats, aged 8-10 weeks, weighing 180-200 g, were divided into 4 groups using a random number table method: sham operation group (group S, n=8), BCP group ( n=40), BCP plus normal saline group (group BCP+ Veh, n=8), and BCP plus NSC23766 group (group BCP+ NSC, n=8). BCP was induced by injecting Walker 256 mammary gland cancer cell suspension 5 μl (1×10 5 cells/μl) into the bone marrow of the right tibia of rats in BCP, BCP+ Veh and BCP+ NSC groups, while the equal volume of inactivated tumor cells were injected in group S. On 9-11 days after BCP, specific Rac1 inhibitor NSC23766 (5 μg/5 μl) was intrathecally injected once a day in group BCP+ NSC, and the equal volume of normal saline (5 μl) was given once a day in group BCP+ Veh.The mechanical paw withdrawal threshold (MWT) was measured at 1 day before BCP (T 0) and 3, 5, 7, 14 and 21 days after BCP (T 1-5). Eight rats in each group were sacrificed after measurement of MWT at each time point in BCP group or after the last measurement of MWT in S, BCP+ Veh and BCP+ NSC groups, and the lumbar segment (L 4-6) of the spinal cord was removed for determination of the expression of Rac1 signaling pathway-related proteins Rac1, GTP-Rac1, PAK1 and p-PAK1 using Western blot. Results:Compared with group S, MWT was significantly decreased at T 3-5 in BCP, BCP+ Veh and BCP+ NSC groups, and the expression of GTP-Rac1 and p-PAK1 was up-regulated at T 3-5 in group BCP ( P<0.05). Compared with group BCP+ Veh, MWT was significantly increased at T 4, 5, and the expression of GTP-Rac1 and p-PAK1 was down-regulated in group BCP+ NSC ( P<0.05). Conclusion:Spinal Rac1 signaling pathway is involved in the maintenance of BCP in rats.

Objective To report a case of frontotemporal dementia with amyotrophic lateral sclerosis (FTD-ALS),review the relevant literature and then summarize the clinical and genetic characteristics of FTD-ALS patients.Methods A FTD-ALS patient admitted to the First Affiliated Hospital,Anhui Medical University in May 2017.After diagnosis,genetic analyses were performed on DNA extracted from peripheral blood of the patient and his first-degree relatives.Chinese FTD-ALS patients reported in detail were reviewed and the clinical and genetic characteristics of the disease were summarized.Results The patient,a 49-year-old man,responded slowly with impaired confrontation naming and impaired single-word comprehension.Magnetic resonance imaging showed temporal lobe atrophy.Besides,the patient gradually developed atrophy in limbs and bulbar muscles as well as spasticity of arms and legs,with positive pathological and primitive reflexes.Electromyography suggested a wide range of neurogenic changes,which were consistent with the FTD-ALS diagnostic criteria.A new heterozygous mutation (c.1335G＞A chr12:64879792 p.W445X) was found in the TBK1 gene.The reference to the American College of Medical Genetics and Genomics guidelines suggested that this mutation type is likely pathogenic,which has not been reported by the Human Gene Mutation Database.There were a total of 21 Chinese FTD-ALS patients (including this case) reported in detail,including 13 males and eight females.The age of onset was (59.01±8.58) (44-73) years.Most of them had typical manifestations of FTD as the first symptom,followed by ALS.Among these patients,seven had genetic data analyses,five of which had positive results.The mutations occurred in TBK1 (two cases),C9onf72 (one case),DCTN1 (one case) and TARDBP (one case)genes,respectively.Most FTD-ALS cases were sporadic (including this case),and only two cases were familial.Conclusions FTD-ALS is a relatively rare disease,mostly sporadic,with a younger onset age,in which behavioral variant FTD is the main manifestation of dementia in the context of ALS,and cognitive impairment is occurred earlier than ALS.In addition to C9orf72 gene,TBK1 gene is an important pathogenic gene of FTD-ALS.Genetic analysis is of great value in the early diagnosis of FTD-ALS.

To examine the risk factors for developing diabetes on its 3-year outcome in an elderly population with impaired fasting glucose (IFG). We selected the 328 elderly with impaired fasting glucose in Binhai new area of Tianjin as the research object. All subjects participated in objective examinations such as physical activity ability tests, blood tests and anthropometric examinations, and completed the questionnaire survey. Between baseline and 3-year outcome, 56 of the subjects with IFG at baseline have developed diabetes. After multivariate adjustments, we found that higher incidence of diabetes was associated with higher fasting plasma glucose (OR=9.30, 95%CI 2.84-30.48, P<0.01) and reduced grip strength/weight (OR=0.88, 95%CI 0.82-0.94, P<0.01). Moreover, the combination of higher fasting plasma glucose and lower grip strength/weight would lead to higher incidence of diabetes compared with higher fasting plasma glucose or lower grip strength/weight alone (P<0.05). In this study, high fasting plasma glucose and low muscle strength were associated with blood glucose worsening in three years in IFG patients. In addition to blood glucose levels, physical activity is also a risk factor for diabetes in older adults.
