Objective To evaluate the symptom improvement of anxiolytics and antidepressant to hemifacial spasm(HFS)patients with anxiety and depression. Methods A total of 60 HFS patients with anxiety and depression were enrolled for the study and divided into experimental group and control group. Experimental group were treated with escitalopram and BTX-A ,and control group only received BTX-A. SAS and SDS were used to test all the patients before and after treatment. Results Both experimental group and control group were significantly improved after BTX-A therapy. There was no different between two groups at 1 week and 1 month,respectively. At 2 weeks and 3 months,more obvious improvement was seen in experimental group. The SAS and the SDS standard average scores of experimental group were significantly decreased compared with the control group. There was statistical significance in control group after 1 month and 3 months treatment(P<0.05),and in experimental group,the differences appeared after 2-week treatment(P<0.05). Additionally,after 1 month treatment,there were statistical differences between the two groups(P<0.05),and experimental group shown a longer effective period compared with control group. Conclusion Anxiety and depression state serves as a complication of HFS ,which is positively correlated with HFS. HFS patients with anxiety and depression benefit better from escital-opram and BTX-A combination therapy than BTX-A alone.

Objective: To investigate the association between the single nucleotide polymorphisms of rs12212067 in FOXO3 gene and the susceptibility to occupational noise-induced deafness in a Chinese Han population. Methods: A total of 1 066 cases of noise exposure workers from a large chemical fiber factory in Jiangsu Province were selected as the study subjects. All subjects’ basic data and field exposure data were collected through questionnaires and occupational health surveys. The subjects were divided into case group (531 persons, double ear high frequency average hearing threshold>25 dB) and control group (535 persons, double ear high frequency average hearing threshold≤25 dB) according to their results of pure tone hearing test .2ml fasting venous blood was collected for DNA extraction and genotyping was performed by TaqMan-PCR technique. Results: Genotyping results suggested that the GT+GG genotype is a risk factor for occupational noise-induced deafness, with an adjusted OR 95% confidence interval of 2.044 (1.51-2.78) . After the noise exposure intensity was stratified, the adjusted OR values and the 95% confidence intervals of noise intensity ≤85, 85-92 and>92 dB respectively 2.43 (1.52-3.90) , 2.17 (1.03-4.59) and 1.74 (1.07-2.83) . Conclusion GT-GG genotype in rs12212067 of FOXO3 gene may be a risk factor for occupational noise-induced deafness.

Objective To systematically review the correlation between fluoride exposure through drinking water and dental fluorosis of school-age children,and to provide a theoretical basis for further development of prevention strategies against dental fluorosis.Methods Such databases as China National Knowledge Infrastructure (CNKI),WanFang Data,VIP Database and China Biology Medicine Disc (CBM) were searched through computer to find out the relationship between fluoride exposure through dringking water and occurrence of dental fluorosis.The retrieval time was from January 1,2000 to January 1,2018.Meta-analysis was performed using RevMan 5.3.Funnel plot and fail-safe method were used to evaluate publication bias,and these data were analyzed sensitivity with random and fixed effect models.Results Totally 20 literatures entered into this study,79 814 people in fluoride exposure group,and 181 876 people in control group.The meta-analysis showed that,20 literatures were inhomogeneous through the heterogeneity test,which was analyzed in the random effect model,the pooled odds ratio (OR) value and 95％ confidence interval (95％CI) was 4.25 (3.66-4.94),which suggested that the risk of dental fluorosis in the fluoride exposure group was 4.25 times higher than that in control group.Funnel plot was asymmetrical,the fail-safe number was 47 791.56,which was 2 389.6 (47 792/20) times higher than included literatures.Literatures publication bias was small,sensitivity analysis revealed that the results were basically reliable.Conclusion Excessive fluoride exposure through dringking water could be one of the main risk factors leading to dental fluorosis.

Objective:To investigate the anatomy of lateral maxillocervical boot-shaped perforator fasciocutaneous flap and its clinical effect on repairing soft tissue defect of zygomatic-temporal region.Methods:(1)From December 2017 to December 2020, five fresh adult cadaver specimens were infused with gelatin lead oxidate and underwent one-time arteriography.The X-ray image was imported into Mimics 17.0 software, divided and colored based on the head and face anatomy, and the distribution and anastomosis of the arteries involved in the lateral maxillocervical boot-shaped perforator fasciocutaneous flap were observed.The head and neck samples of another 5 (10 sides) fresh adult cadavers were infused with red latex artery to establish the surgical model, and then dissected layer by layer to investigate the blood supply and the source of perforating artery of this flap.(2) The patients with zygomatic-temporal lesions were treated in the Department of Plastic Surgery, the First Affiliated Hospital of Anhui Medical University.They were treated with the lateral maxillocervical boot-shaped perforator fasciocutaneous flap to repair the wound left after lesion resection. The survival of the flap and the healing of the incision were observed after surgery and the appearance and sensation of donor and recipient sites as well as tumor recurrence were followed up.Results:(1) The pedicle of the lateral maxillocervical boot-shaped perforator fasciocutaneous flap is mainly nourished by the superficial temporal artery and its perforator.The average diameter of the maximum three perforations is (0.44±0.04) mm, (0.90±0.08) mm, (0.73±0.05) mm.The fascial vascular network and subdermal vascular network formed by perforating arteries from superficial temporal artery and branching arteries from facial artery at different layers are the anatomical basis for ensuring blood supply of lateral maxillocervical boot-shaped perforator fasciocutaneous flap. (2) A total of 12 patients with zygomatic-temporal lesions were treated clinically, including 8 males and 4 females aged 42-79 years, including 2 cases of senile sebaceous keratosis, 3 cases of squamous cell carcinoma, 1 case of skin ulcer and 6 cases of basal cell carcinoma. The range of defect after resection of the lesions was 4 cm×3 cm-9 cm×8 cm. The flap area was 5 cm×3 cm-11 cm×9 cm, the flap pedicle width was 2-3 cm, length was 2-4 cm, After surgery, the blood supply of the flap was good without necrosis, the wound were covered by first treatment. After 6-18 months of follow-up, the donor and recipient areas presented natural appearance, no swelling, no paresthesia and facial paralysis, and no recurrence of cancer.Conclusions:The lateral maxillocervical boot-shaped perforator fasciocutaneous flap pedicled with perforating branch of superficial temporal artery has reliable blood supply. Using this flap to repair large soft tissue defects in zygomatic-temporal region has the advantages of simple operation, similar color and texture, and good appearance.

Objective To investigate the awareness status of iodine deficiency disorders (IDD) prevention and treatment knowledge of target population in Hubei Province, and to evaluate the intervention effect of IDD health education. Methods From 2013 to 2016, 13 counties (cities and districts) were selected as project counties in Hubei Province each year and 7 counties (cities and districts) were selected each year in 2017-2018. Three townships (towns) were chosen in each project county, and the health education activities were carried out among the grade 4-6 students in the central primary school of each township (town). Three administrative villages were selected in each township (town) to carry out community health education activities. Before and after the implementation of health education, 30 students in a fifth grade class from each central elementary school, and 15 housewives around the school were selected to conduct a questionnaire survey on IDD prevention and control knowledge. Results Totally 5 940 elementary school students and 2,970 housewives were investigated from 2013-2018. After carrying out IDD health education activities, the awareness rates of IDD prevention knowledge among primary school students and housewives were 94.28% (16 801/17 820) and 93.20% (8 304/8 910), respectively, which increased significantly compared with those before the health education intervention [71.60% (12 759/17 820) and 70.93% (6 320/8 910), respectively]. The differences were statistically significant (χ²=3,239.83, 1,500.78，P<0.01). Among the primary school students and housewives, the knowledge awareness rates of IDD prevention and treatment were increased by 22.68% and 22.27%, respectively. Conclusion Health education intervention could significantly increase the awareness of IDD among primary school students and housewives, and it is an important measure to maintain IDD elimination status.
