ABSTRACT
Objective: To understand the depression status and its influencing factors in elderly patients with MS in China and to explore the correlation between various components of elderly MS and depression. Methods: This study is based on the "Prevention and Intervention of Key Diseases in Elderly" project. We used a multi-stage stratified cluster random sampling method to complete 16 199 elderly aged 60 years and above in 16 counties (districts) in Liaoning, Henan, and Guangdong Provinces in 2019, excluding 1 001 missing variables. Finally, 15 198 valid samples were included for analysis. The respondents' MS disease was obtained through questionnaires and physical examinations, and the respondents' depression status within the past half month was assessed using the PHQ-9 Depression Screening Scale. The correlation between elderly MS and its components and depression and its influencing factors were analyzed by logistic regression. Results: A total of 15 198 elderly aged 60 years and above were included in this study, with the prevalence of MS at 10.84% and the detection rate of depressive symptoms in MS patients at 25.49%. The detection rates of depressive symptoms in patients with 0, 1, 2, 3, and 4 MS abnormal group scores were 14.56%, 15.17%, 18.01%, 25.21%, and 26.65%, respectively. The number of abnormal components of MS was positively correlated with the detection rate of depressive symptoms, and the difference between groups was statistically significant (P<0.05). The risk of depression symptoms in patients with MS, overweight/obesity, hypertension, diabetes, and dyslipidemia was 1.73 times (OR=1.73, 95%CI:1.51-1.97), 1.13 times (OR=1.13, 95%CI:1.03-1.24), 1.25 times (OR=1.25, 95%CI:1.14-1.38), 1.41 times (OR=1.41, 95%CI:1.24-1.60), 1.81 times (OR=1.81,95%CI:1.61-2.04), respectively, more than those without the disease. Multivariate logistic regression analysis showed that the detection rate of depressive symptoms in patients with sleep disorders was higher than that with normal sleep (OR=4.89, 95%CI: 3.79-6.32). The detection rate of depressive symptoms in patients with cognitive dysfunction was 2.12 times higher than that in the average population (OR=2.12, 95%CI: 1.56-2.89). The detection rate of depressive symptoms in patients with impaired instrumental activities of daily living (IADL) was 2.31 times (OR=2.31, 95%CI: 1.64-3.26) higher than that in the average population. Tea drinking (OR=0.73, 95%CI: 0.54-0.98) and physical exercise (OR=0.67, 95%CI: 0.49-0.90) seemed to be protective factors for depression in elderly MS patients (P<0.05). Conclusions: Older patients with MS and its component abnormalities have a higher risk of depression than the average population. Sleep disorders, cognitive impairment, and IADL impairment are important influencing factors for depression in elderly MS patients, while tea drinking and physical exercise may help to reduce the risk of the disease.

Rheumatoid arthritis(RA), as a chronic autoimmune disease, has a high incidence and disability rate, causing significant suffering to patients. Due to its complex pathogenesis, it has not been fully elucidated to date, and its treatment remains a challenging problem in the medical field. Although western medicine treatment options have certain efficacy, they require prolonged use and are expensive. Additionally, they carry risks of multiple infections and adverse reactions like malignancies. The Chinese herbal medicine Rhododendron molle is commonly used in folk medicine for its properties of dispelling wind, removing dampness, calming nerves, and alleviating pain in the treatment of diseases like rheumatic bone diseases. In recent years, modern clinical and pharmacological studies have shown that the diterpenoids in R. molle are effective components, exhibiting immune-regulatory, anti-inflammatory, and analgesic effects. This makes it a promising candidate for treating RA with a broad range of potential applications. However, R. molle has certain toxic properties that hinder its clinical application and lead to the wastage of its resources. This study reviewed recent research progress on the mechanism of R. molle in preventing and treating RA, focusing on its chemical components, anti-inflammatory and analgesic properties and summarized the adverse reactions associated with R. molle, aiming to offer new ideas for finding natural remedies for RA and methods to reduce toxicity while enhancing the effectiveness of R. molle. The study seeks to clarify the safety and efficacy of R. molle and its extracts, providing a theoretical basis for its application prospects and further promoting the development and utilization of R. molle resources.

ABSTRACT
OBJECTIVE@#To evaluate the predictive value of pre-treatment serum uric acid (sUA) level for the prognosis of newly diagnosed multiple myeloma (NDMM) patients.@*METHODS@#The NDMM patients admitted to our center from January 2014 to December 2018 were analyzed retrospectively, and 94 patients among them who were initially treated with bortezomib-based chemotherapy for at least 4 cycles were included in this study. Clinical characteristics, laboratory data and follow-up information were collected, and the predictive value of sUA on the overall survival (OS) of NDMM was evaluated by using receiver operating characteristic (ROC) curve based on the patient's pre-treatment sUA level and the survival status at the end of follow-up, and the correlation of the sUA level with patient's clinical, laboratory characteristics and overall survival (OS) was further analyzed. The univariate and multivariate Cox proportional-hazards model were used to identify the potential factors affecting OS.@*RESULTS@#ROC analysis showed that the area under the curve for predicting OS in NDMM patients with sUA level was 0.702 (P<0.001), and the optimal cut-off value was 455.4 μmol/L. Compared to patients with low sUA (<455.4 μmol/L), patients with higher sUA (≥455.4 μmol/L) were more likely to have international staging system (ISS) stage III disease, beta2-microglobulin (β@*CONCLUSION@#Pre-treatment sUA level is a potential biomarker for the prognosis evaluation in NDMM patients, which deserves a further exploration and verification.

BACKGROUND@#Drug-coated balloons (DCBs) have emerged as potential alternatives to drug-eluting stents in specific lesion subsets for de novo coronary lesions. Quantitative flow ratio (QFR) is a method based on the three-dimensional quantitative coronary angiography and contrast flow velocity during coronary angiography (CAG), obviating the need for an invasive fractional flow reserve procedural. This study aimed to assess the serial angiographic changes of de novo lesions post-DCB therapy and further explore the cut-off values of lesion and vessel QFR, which predict vessel restenosis (diameter stenosis [DS] ≥50%) at mid-term follow-up.@*METHODS@#The data of patients who underwent DCB therapy between January 2014 and December 2019 from the multicenter hospital were retrospectively collected for QFR analysis. From their QFR performances, which were analyzed by CAG images at follow-up, we divided them into two groups: group A, showing target vessel DS ≥50%, and group B, showing target vessel DS <50%. The median follow-up time was 287 days in group A and 227 days in group B. We compared the clinical characteristics, parameters during DCB therapy, and QFR performances, which were analyzed by CAG images between the two groups, in need to explore the cut-off value of lesion/vessel QFR which can predict vessel restenosis. Student's t test was used for the comparison of normally distributed continuous data, Mann-Whitney U test for the comparison of non-normally distributed continuous data, and receiver operating characteristic (ROC) curves for the evaluation of QFR performance which can predict vessel restenosis (DS ≥50%) at mid-term follow-up using the area under the curve (AUC).@*RESULTS@#A total of 112 patients with 112 target vessels were enrolled in this study. Group A had 41 patients, while group B had 71. Vessel QFR and lesion QFR were lower in group A than in group B post-DCB therapy, and the cut-off values of lesion QFR and vessel QFR in the ROC analysis to predict target vessel DS ≥50% post-DCB therapy were 0.905 (AUC, 0.741 [95% confidence interval, CI: 0.645, 0.837]; sensitivity, 0.817; specificity, 0.561; P < 0.001) and 0.890 (AUC, 0.796 [95% CI: 0.709, 0.882]; sensitivity, 0.746; specificity, 0.780; P < 0.001).@*CONCLUSIONS@#The cut-off values of lesion QFR and vessel QFR can assist in predicting the angiographic changes post-DCB therapy. When lesion/vessel QFR values are <0.905/0.890 post-DCB therapy, a higher risk of vessel restenosis is potentially predicted at follow-up.

ABSTRACT
Objective To study the influences of mental disorders on female systemic lupus erythematosus(SLE)and analyze the factors. Methods We used symptom check list -90 (SCL-90) as a basis for judging mental disorders disease activity. Disease activity, social support and depreciation - discrimination were used as possible influencing factors. Social support and discomfort – discrimination were possible influencing factors. Multivariate unconditional logistic regression model was used to analyze the influencing factors of mental disorders. Results The total score of SCL-90 of patients with female SLE was significantly higher than that of norm models [(136.39±48.66) vs (129.96±38.76)] (P<0.05), in 289 SLE patients, the number of patients with mental disorders was 128 (44.3%). High monthly income(OR=0.770, 95% CI:0.604-0.981, P=0.034) was a protective factor for mental disorders. High disease activity (OR=1.792, 95% CI:1.023-3.138, P=0.042)and high discomfort–discrimination (OR=1.100, 95% CI:1.035-1.169, P=0.002)were risk factors for mental disorders. Conclusions Female SLE patients have a higher risk of mental disorders than the general population. And eliminating self-depreciation, reducing social discrimination, active employment, increasing monthly income, standardizing treatment and reducing disease activity may effectively alleviate mental disorders in SLE patients.

Objective There are few comparative researches on open reduction internal fixation, hemishoulder arthroplasty and reverse total shoulder arthroplasty for the treatment of complex proximal humeral fractures. The purpose of this study was to explore the clinical efficacy of three surgical Methods for the treatment of complex proximal humeral fractures.Methods A retrospective study of 55 cases of complex proximal humeral fractures treated in our department from November 2013 to May 2016. According to different surgical Methods , the patients were divided into three groups: open reduction internal fixation group of 20 cases (open reduction and internal fixation using locking plate), hemishoulder arthroplasty group of 20 cases (artificial humeral head replacement), reverse total shoulder arthroplasty group of 15 cases (head-glenoid inverted shoulder replacement). Regular postoperative review was done to record the ranges of motion. The function of shoulder joint was evaluated by ASES score, VAS pain score, UCLA score and SST score.Results 6 months after the operation, the internal rotation function of the hemishoulder arthroplasty group\[(49.1±3.3)°\] was better than those of reverse total shoulder arthroplasty group \[(43.7±4.5)°\] and open reduction internal fixation group \[(41.7±5.0)°\], but the external rotation function\[(25.7±5.4)°\] was worse than the other two groups\[(38.0±5.6)°, (39.5±4.6)°\], the differences representing statistical significance(P0.05).Conclusion Three surgical Methods can all be used in the treatment of complex proximal humeral fractures with equivalent efficacy. Reverse total shoulder arthroplasty leads to earlier shoulder joint range of motion, but lacks middle-term and long-term curative effect. Clinicians should take surgical indications and individualization into consideration comprehensively to make the choice among three surgical Methods .
ABSTRACT
BACKGROUND: Plating ankle arthrodesis includes anterior and lateral plating methods, but there is some lack of knowledge about their differences in biomechanics. OBJECTIVE: To establish the three-dimensional models of anterior and lateral plating ankle arthrodesis through three-dimensional finite element technique, simulate human gait, and to analyze its biomechanical stability and safety. METHODS: The geometrical morphology of ankle joint was reconstructed based on the normal human ankle CT data. The models of anterior and lateral plating ankle arthrodesis were established using finite element analysis software Abaqus 2016, and the biomechanical changes after exerting stress at the positions of intorsion,extorsion, dorsiflexion, and neutral were analyzed. RESULTS AND CONCLUSION: (1) The maximal displacement and stress distribution under different stress were compared between two models by three-dimensional element analysis, and there was no significant difference in the stability between two models. (2) The abilities of resistance to intorsion and dorsiflexion stresses of the lateral plating model were slightly better than those of the anterior plating model, but the resistance to extorsion stress of the lateral plating model was lower than that of the anterior plating model; the stress peak both concentrated on the plate-screw connections. (3) The plate, screw and bone mass of the anterior plating model showed the maximum stress peak under intorsion stress, and broken plates and nails usually occur. (4) The lateral plating presented with peak stress under extorsion stress.
ABSTRACT
Purpose To identify the binding of hypoxia in-ducible factor-2a (HIF-2 a) to the hypoxia-response element(HRE) of the matrixmetallo proteinases-2 (MMP-2) gene promoter region and clear the binding site. Methods Electro-phoretic mobility shift assay (EMSA) was used to identify the binding of HIF-2 a to HRE of the MMP-2 gene promoter region in vitro. At the same time, the chromatin immunoprecipitation assay (CHIP) was used to further determine the binding site. Results Successful prediction of two potential HIF-2a binding sites of MMP-2 the promoter region, which were-217~-204 and-1 029 ~-1 007, respectively. Probe test shows that the marked efficiency of sense chain and antisense chain was above 50%, and they could be used for EMSA-electrophoretic mobility shift assay. The results of EMSA showed that there was a binding site of HIF-2 a sense chain and antisense chain moter region int-217~-204. The results of chromatin immuno-precipitation showed that in the experimental group and control group an about 250 bp fragment in MMP-2 promoter containing HRE region was amplified, suggesting that the protein of HIF-2a binded to the HRE in MMP-2 promoter region in vivo. Conclusion HIF-2 a in MMP-2 promoter regionne promoter region in vitro and in vivo.

ABSTRACT
Objectives: To investigate the relationships between the stability of carotid plaque and serum Lp-PLA2, A-FABP levels in hypertensive postmenopausal women. Methods: 195 postmenopausal women with hypertension were selected and divided into non-plaque group, stable plaque group and unstable plaque group according to the results of carotid intima-media thickness (IMT) and plaque types derived from color doppler ultrasonography. In addition, 40 healthy postmenopausal women were recruited as normal control group. The serum Lp-PLA2 and A-FABP levels of all subjects were measured. Lp-PLA2 and A-FABP levels were compared among four groups by One-Way ANOVA. Spearman correlation analysis and multiple logistic regression analysis were also performed. Results: Plaque group included 123 subjects (unstable plaque group: 29 cases; stable plaque group: 94 cases), and non-plaque group included 72 subjects. The average serum A-FABP level was significantly higher in unstable plaque group [(172.60±33.70) ng/L] than in non-plaque group[(133.04±29.49) ng/L], P<0.05. Serum Lp-PLA2 level was similar between the four groups, P>0.05. Serum A-FABP level was positively correlated with the carotid plaque (r=0.3446, P=0.0049);serum Lp-PLA2 level was not correlated with the carotid plaque (r=0.2058, P=0.0996). Multiple logistic regression analysis showed that high A-FABP level was associated with stable plaque in hypertensive postmenopausal women (P=0.040, OR=1.017, 95%CI: 1.001~1.033), which was also associated with unstable plaque in this population (P=0.003, OR=1.031, 95%CI: 1.010~1.052). Conclusions: The level of A-FABP is a determinant responsible for the occurrence and stability of carotid plaque among hypertensive postmenopausal women. There was no correlation between Lp-PLA2 level and the stability of carotid plaque in this patient cohort.

ABSTRACT
<p><b>BACKGROUND</b>β-adrenoceptors play a crucial regulatory role in blood vessel endothelial cells. Isoprenaline (ISO, a β-adrenergic agonist) has been reported to promote angiogenesis through upregulation of vascular endothelial growth factor (VEGF) expression; however, the underlying mechanism remains to be investigated. It is widely accepted that certain noncoding RNAs, including microRNAs (miRNAs) and long noncoding RNAs (lncRNAs), can regulate endothelial cell behavior, including their involvement in angiogenesis. Therefore, we aimed to investigate whether noncoding RNAs participate in ISO-mediated angiogenesis using human umbilical vein endothelial cells (HUVECs).</p><p><b>METHODS</b>We evaluated VEGF-A messenger RNA (mRNA) and protein levels in ISO-treated HUVECs by quantitative real-time polymerase chain reaction and enzyme-linked immunosorbent assay, respectively. To establish whether noncoding RNAs are associated with ISO-mediated angiogenesis, we measured expression of the miRNAs miR-210, miR-21, and miR-1, as well as that of the lncRNAs growth arrest-specific transcript 5 (GAS5), maternally expressed 3 (MEG3), and metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) in HUVECs exposed to ISO. Furthermore, to ascertain its importance in ISO-mediated angiogenesis, we constructed the HUVECs with overexpressing miR-210 and detected the subsequent expression of VEGF-A and noncoding RNAs. All statistical analyses were performed using SPSS 16.0 software. Intergroup comparisons were carried out by one-way analysis of variance.</p><p><b>RESULTS</b>VEGF-A mRNA levels were elevated in the ISO group (1.57 ± 0.09) compared to those in the control group (P < 0.01). Moreover, concentrations of VEGF-A in culture supernatants significantly differed between the control (113.00 ± 19.21 pg/ml) and ISO groups (287.00 ± 20.27 pg/ml; P< 0.01). Expression of miR-1, miR-21, and miR-210 was higher (3.89 ± 0.44, 2.87 ± 087, and 3.33 ± 1.31, respectively) in ISO-treated cells than that in controls (P < 0.01), whereas that of GAS5 and MEG3 (0.22 ± 0.10 and 0.58 ± 0.16, respectively) was lower as a result of ISO administration (P < 0.05). There was no significant difference in the expression of MALAT1 between the groups. Interestingly, miR-210 overexpression heightened the levels of VEGF-A and miR-21 (5.87 ± 1.24 and 2.74 ± 1.15, respectively; P< 0.01) and reduced those of GAS5 and MEG3 (0.19 ± 0.01 and 0.09 ± 0.05, respectively; P< 0.01).</p><p><b>CONCLUSIONS</b>ISO-mediated angiogenesis was associated with altered expression of miR-210, miR-21, and the lncRNAs GAS5 and MEG3. The effects of miR-210 on the expression of VEGF-A and noncoding RNAs were similar to those of ISO, indicating that it might play an important role in ISO-mediated angiogenesis.</p>

<p><b>OBJECTIVE</b>To investigate the current status and distribution features of cognitive function among the elderly population of China.</p><p><b>METHODS</b>A total of 18 137 subjects aged over 60 years old from 2010 Chronic Non-communicable Disease & Risk Factor Surveillance in China were selected in this study. Questionnaire was used to collect the information about gender, age and health status. The Mini-Mental State Examination (MMSE) was adopted as an instrument to measure the cognitive function of adult who had self-reported memory decline. After performing complex weighted analysis, the current status of cognitive function and the prevalence of cognitive disorder were compared by different genders, age groups, urban/rural and education levels.</p><p><b>RESULTS</b>Among the 18 086 subjects, the median of MMSE sore was 23. The score was higher in males (25) than in females (22) and it was higher in urban (25) than in rural area (22). The cognitive function declined with age increasing. The group of people aging 60-64 years old had the highest score (26), and the group of people aging ≥ 80 years old had the lowest score (19). The MMSE score rose up with education level increasing, the group of people with education level above middle school had the highest score (28) and the group of illiterate people had the lowest score (20). The prevalence of overall cognitive disorder was 10.12% (95%CI: 8.22%-12.02%). The female prevalence (12.45%, 95%CI:9.95%-14.94%) was higher than male prevalence (7.68%, 95%CI:5.94%-9.43%). The group of people aged 60-64 years old had the lowest prevalence (4.69%, 95%CI:3.40%-5.98%), and the people aged ≥ 80 years old had the highest prevalence (22.43%, 95%CI:17.80%-27.05%). The prevalence increased with age increasing (χ(2) = 320.02, P < 0.01). The prevalence of cognitive disorder in illiterate group was 14.6% (95%CI:12.01%-17.23%), and it was separately 6.92% (95%CI: 5.21%-8.64%) and 3.99% (95%CI: 2.58%-5.40%) in group of people with education background of primary school and middle school. The prevalence decreased with education levels increasing (χ(2) = 156.49, P < 0.01). Married or cohabiting elderly people had the lowest prevalence (8.51%, 95%CI: 6.58%-10.43%), lower than single ones (9.32%, 95%CI: 4.00%-14.64%) and divorced ones (14.89%, 95%CI: 12.37%-17.50%). The prevalence of cognitive disorder among rural population (12.16%, 95%CI: 9.51%-14.82%) was higher than it among urban population (5.93%, 95%CI: 4.78%-7.07%). The prevalence in central area (13.57%, 95%CI: 8.55%-18.58%) was higher than that in east (7.96%, 95%CI: 6.17%-9.74%) and west region (9.50%, 95%CI: 7.62%-11.38%) of China.

<p><b>OBJECTIVE</b>To investigate the current status and association between movement disorders, constipation and sleep disturbances in the elderly population of China.</p><p><b>METHODS</b>A total of 42 353 subjects aged over 60 years old from Chinese Chronic Non-communicable Disease & Risk Factor Surveillance (2010) was selected in our study. The information on movement disorders, constipation and sleep disturbances was collected by standardized questionnaire interview. The prevalence and association of self-reported movement disorders, constipation and sleep disturbances was measured according to different gender, age groups and regions.</p><p><b>RESULTS</b>The study was conducted among 42 353 old adults, including 21 893 males (51.7%) and 20 460 females (48.3%); 17 917 from urban areas (42.3%) and 24 436 from rural areas (57.7%); and the proportion of elderly from eastern, central and western regions were 37.9% (16 031 subjects), 29.1% (12 345 subjects) and 33.0% (13 977 subjects) respectively. After weighted complex analysis, the data showed that among the elderly population over 60 years old in China, the self-reported rates of movement disorders, constipation and sleep disturbances were all age-related, rising up with the age increasing. The rates of 60-64 age group were 2.8% (95%CI:1.9%-3.7%), 3.6% (95%CI:3.1%-4.1%) and 12.4% (95%CI:11.0%-13.8%);and in ≥ 80 age group, the rates were 13.2% (95%CI:10.2%-16.1%), 8.8% (95%CI:7.1%-10.6%) and 19.1% (95%CI:16.3%-21.9%). The self-reported rate of movement disorders was 5.7% (95%CI: 4.5%-7.0%); the prevalence of constipation was 5.1% (95%CI: 4.4%-5.7%), which was higher among women (5.8%, 95%CI: 5.0%-6.6%) than it among men (4.3%, 95%CI: 3.7%-4.8%) (χ(2) = 23.40, P < 0.05), and higher among subjects from urban areas (6.0%, 95%CI: 5.1%-7.0%) than from rural areas (4.6%, 95%CI: 3.8%-5.4%) (χ(2) = 5.62, P < 0.05); the prevalence of self-reported sleep disturbances was 14.2% (95%CI: 12.7%-15.8%), higher in women (17.4%, 95%CI: 15.4%-19.3%) than in men (11.0%, 95%CI: 9.7%-12.2%) (χ(2) = 172.05, P < 0.05); the prevalence of movement disorders in people with constipation (16.3%, 95%CI: 12.7%-19.9%) was much higher than it in people without constipation (5.2%, 95%CI: 4.0%-6.3%) (χ(2) = 242.73, P < 0.05); and the prevalence of movement disorders in people with sleep disturbances (13.0%, 95%CI: 10.6%-15.4%) was much higher than it in people without sleep disturbances (4.5%, 95%CI: 3.5%-5.5%) (χ(2) = 688.80, P < 0.05).Logistic regression analysis showed that constipation and sleep disturbances would increase the risk of movement disorders, with the OR (95%CI) at 2.93 (2.57-3.33) and 2.73 (2.48-3.02), respectively.</p><p><b>CONCLUSION</b>The present study showed that self-reported rates of movement disorders, constipation and sleep disturbances all rose up with age increasing in the elderly.

This study is to evaluate the sustained-release effect of the thermosensitive in situ gel for injection of boanmycin hydrochloride (BAM) by bioluminescence imaging in nude mice. BAM was labeled with fluorescein isothiocyanate (FITC). The FITC-labeled BAM (FITC-BAM) was purified by dialysis and Sephadex G25 gel column, and then was identified by matrix-assisted laser desorption ionization/time of flight (MALDI-TOF). The model of experimental hepatoma HepG-2 nude mice was established, and the optical imaging system was applied to evaluate the distribution of FITC-BAM in vivo. Results of MALDI-TOF proved that the major molecular ratio of BAM : FITC was 1 : 1 or 1 : 2. Bioluminescence imaging showed that the diffusion of FITC-BAM in situ gel group was significantly delayed compared with the negative control group. This study demonstrated that the thermosensitive in situ gel can effectively delay the release of boanmycin hydrochloride, and extend the retention time in vivo.

<p><b>OBJECTIVE</b>To investigate the effects of three differently concentrated at-home bleaching agents on the structure and the structure-related mechanical properties of human enamel.</p><p><b>METHODS</b>Sixty enamel specimens were randomly divided into four groups and treated with 10% carbamide peroxide (CP), 15% CP, 20% CP and distilled water, respectively. The bleaching process was 8 h/day for 14 consecutive days. Baseline and final atomic force microscopy (AFM) surface detection, Raman spectroscopy, attenuated total reflectance-infrared spectroscopy (ATR-IR), microhardness and fracture toughness (FT) measurements were carried out before and after bleaching experiments.</p><p><b>RESULTS</b>CP didn't change the morphology of enamel. Meanwhile, the three bleached groups and the control group had no significant difference in root mean square detection (P = 0.774), ν(2)CO(3)(2-) : ν(1)ν(3)PO(4)(3-) (P = 0.263) and microhardness (P = 0.829). The percentage of relative Raman intensity in the three bleached groups and the control group were (105.74 ± 11.34)%, (104.46 ± 8.83)%, (99.52 ± 9.32)% and (97.62 ± 7.46)%, respectively. There was no significant difference among them (P = 0.062). However, the percentage of laser-induced fluorescence in the three bleached groups and the control group were (20.86 ± 7.23)%, (22.14 ± 7.34)%, (21.10 ± 7.59)% and (100.78 ± 3.70)%, respectively. There was significant difference between either of the bleached groups and the control group (P < 0.001). Moreover, FT declined significantly in the three groups (P = 0.024, P = 0.005, P = 0.013) when compared with the control group.</p><p><b>CONCLUSIONS</b>Under in vitro condition, three differently concentrated at-home bleaching agents wouldn't induce the demineralization and the decline of microhardness on enamel. However, the decrease of FT on enamel seemed to be inevitable after bleaching.</p>
