OBJECTIVEFrictions of Lock-loose brackets with ligated main wings or all six wings were measured as they slid along archwires in dry and artificial saliva environments. The Lock-loose brackets were then compared with traditional brackets and self-ligating brackets.

METHODSThe surface states of the stainless steel archwires were observed with atomic force microscopy before and after mechanical traction. The Lock-loose brackets, traditional brackets, and self-ligating brackets used in this study were composed of 0.406 4 and 0.457 2 mm stainless steel round archwires and 0.457 2 mm x 0.634 9 mm and 0.482 6 mm x 0.634 9 mm stainless steel rectangular archwires. Two different ligating methods were applied to the Lock-loose brackets, i.e., main wings ligated and all six wings ligated. Frictions were measured by using an electronic universal testing machine.

RESULTSNo significant differences were found between the roughness of different archwires before and after mechanical traction in different brackets (P > 0.05). When the main wings of the Lock-loose brackets were ligated, the frictions of the four different stainless steel archwires were close to zero, and the difference with frictions of traditional brackets was significant (P < 0.05). When using 0.457 2 mm x 0.634 9 mm rectangular archwires, maximum friction (P < 0.05; significantly different from those of other brackets) was reached when all six wings of the Lock-loose brackets were ligated. Frictions in the dry state were higher than those in the wet state (P < 0.05).

CONCLUSIONThe Lock-loose brackets can adjust the friction efficiently with different ligating methods, thus solving the problem of low friction and strengthening anchorage.

Objective:To explore the impact of pain, functional disability, self-efficacy and social support on health-related quality of life (HRQOL) in gout patients.Methods:From November 2019 to January 2020, a total of 218 patients with gout were investigated using the general information questionnaire, Visual Analogue Scale, Health Assessment Questionnaire Disability Index, General Self-Efficacy Scale, Perceived Social Support Scale, and Gout Impact Scale. The structural equation model was established by AMOS 24.0 for parth analysis, and the mechanism of pain dysfuction, self-efficacy and social support affecting the quality of life in gout patients was tested.Results:The total score of Gout Impact Scale, pain, functional disability, self-efficacy and social support respectively was 59.94±18.39, 6.00±2.76, 0.25 0, 0.88, 23.39±6.40 and 62.92±8.24. Pain directly influenced HRQOL ( β=-0.293, P<0.01), and indirectly influenced HRQOL ( β=-0.039, P<0.05). Functional disability directly influenced HRQOL ( β=-0.244, P<0.01). Self-efficacy directly influenced HRQOL ( β=0.182, P<0.01), and indirectly influenced HRQOL ( β=0.202, P<0.01) through pain and functional disability. Social support indirectly influenced HRQOL ( β=0.278, P<0.01) through pain, functional disability and self-efficacy. Conclusions:HRQOL of patients among gout is affected by several factors, mainly affected by pain, functional disability and self-efficacy; and there are interactions among them. Targeted interventions should be strengthened to relieve pain, prevent or slow down the progress of physical disability, enhance self-efficacy and social support to improve HRQOL.

Objective:To observe the efficiency of tunnel-type partial superficial parotidectomy(T-PSP)in the treatment of benign tumor in the inferior pole of parotid gland.Methods:53 patients with benign tumors in the superficial sublobular pole of the parotid gland were included.27 cases were treated with T-PSP(trial group)and 26 with partial superficial parotidectomy(PSP)(control group).The patients were followed up for 1-3 years.The incidence of facial nerve palsy,Frey's syndrome,salivary fistula,periauricu-lar numbness and skin numbness in the parotid area in the 2 groups was compared.Results:Complications such as facial nerve palsy,Frey's syndrome,periauricular numbness and skin numbness in the parotid area were less frequent in the trial group than in the control group(P＜0.05),while there was no significant difference in the incidence of salivary fistulae between the 2 groups(P＞0.05).No tumor relaps was observed in all cases.Conclusion:T-PSP has fewer postoperative complications in the treatment of benign tumours benign tumor in the inferior pole of parotid gland.

Objective:Gastrointestinal heat retention syndrome (GHRS) is associated with lung-heat syndrome and is related to recurrent respiratory infection.Upper respiratory tract infection (URTI) lung heat syndrome is common in children.The study will explore the effect of GHRS on the structure and function of gut microbiota in children with URTI lung-heat syndrome.Methods:Participants were divided into both groups using the self-developed URTI scale and the "GHRS Diagnostic Scale · Pediatric Part":GHRS-positive children (LS group) and GHRS-negative children (L group).General information,clinical symptoms,and stool were collected.We used 16S rRNA amplicon sequencing technology to determine the gene sequence of the V3-V4 region in feces and measure the gut microbiota of the both groups at the genus level.Results:A total of 23 children were included in the both groups.There were 12 cases in the LS group and 11 cases in the L group.There was no statistical difference between the both groups in age,gender,height,weight,and body mass index.The effective sequences shared by the both groups accounted for 85.66％ of the total.In the gut microbiota,there was no difference in the α diversity and the β diversity between the both groups.Compared with the L group,the LS group had a significant increase in the relative abundance of the Rurninococcus gnavus group,Prevotella-9,Staphylococcus,and Actinomyces(P ＜.05).The functions of the both groups of microbiota primarily concentrate on metabolism,genetic information processing,and environmental information processing.The relative abundance of signaling molecules and interactions in the LS group were higher than that in the L group (P ＜.05).The redun-dancy analysis (RDA) showed that the URTI score had the greatest impact on the distribution of microbiota.Conclusion:GHRS may affect the development of URTI lung-heat syndrome by changing the relative abundances of gut microbiota.

Objective:To explore the difference of inflammatory factor imbalance between adolescent and adult patients with depression.Methods:A total of 30 adolescent and 30 adult patients with depression, and 30 adolescent and 30 adult healthy controls were included from January 2022 to August 2023. Interleukin-6 (IL-6), interleukin-17 (IL-17), transforming growth factor-beta1(TGF-β1), interleukin-10(IL-10) and Maresin-1(MaR1) level were detected by enzyme-linked immunosorbent assay. 24-item Hamilton depression scale (HAMD-24) was used to assess the severity of depression in all depressed patients. SPSS 26.0 statistical software was used for t-test, covariance analysis, Spearman analysis and multivariate binary logistic regression, and the predictive value of selected inflammatory factors in depression was evaluated by receiver operating characteristic(ROC) curve. Results:(1)In adolescent group, the levels of IL-6 ((64.000±38.632) pg/mL), IL-17((239.132±49.757) pg/mL), and TGF-β1((737.267±328.447)pg/mL) in patients with depression were higher than those in control group((32.396±16.330)pg/mL, (214.954±42.326)pg/mL, (454.542±297.194)pg/mL, all P<0.05), while the level of MaR1((21 381.301±3 946.011)pg/mL) was significantly lower than that in control group((30 130.138±10 278.999)pg/mL)( P<0.001). The level of IL-17 was positively correlated with the total score of HAMD-24 ( r=0.429) and the course of disease ( r=0.571), the level of IL-10 was negatively correlated with body weight factor score ( r=-0.384), and the levels of TGF-β1 was negatively correlated with anxiety/somatization factor score ( r=-0.449)(all P<0.05) in adolescent patients with depression.MaR1( B=0.000 1, OR=0.999 8, AUC=0.794, P<0.05) was an independent risk factor for adolescents depression.(2)In adult depression group, the levels of IL-6, IL-17, IL-10, TGF-β1 and MaR1 were higher than those in adult control group(all P<0.05). The level of TGF-β1 in adult depression group was negatively correlated with the total score of HAMD-24 ( r=-0.427), the score of anxiety/somatization factor ( r=-0.368), the score of blocking factor ( r=-0.405), and the score of hopelessness factor ( r=-0.398).The level of MaR1 was positively correlated with the age of onset of disease ( r=0.425)(all P<0.05) in adult patients with depression.MaR1( B=0.000 4, OR=1.000 3, AUC=0.874, P<0.001) and IL-6( B=0.040, OR=1.040 7, AUC=0.779, P<0.05) were independent risk factors for adult depression.The AUC of IL-6 combined with MaR1 was 0.938. Conclusion:There are differences in the underlying mechanism of immune imbalance between adolescent and adult patients with depression.MaR1 may be a diagnostic biomarker for depression in adolescents and adults.
