Abstract
Objective: To analyze the clinical characteristics of 34 COVID-19 cases and to provide the basis for the prevention and control of the epidemic disease. Methods: Thirty-four COVID-19 patients diagnosed with RT-PCR in the isolation ward of the Fourth People's Hospital of Ningxia Hui autonomous region (infectious diseases hospital) from the January 22 to February 4, 2020 were selected as the research subjects. The clinical data were collected. Excel was used to describe the relationship between clinical classification and age distribution, contact history and date of onset. SPSS 25.0 statistical software was used for analysis. The general information, clinical symptoms, blood test, virus nucleic acid test results, epidemiology, CT imaging, treatment and prognosis were analyzed. Results: There were 5 mild cases (5/34), 24 ordinary cases (24/34), 5 severe cases (5/34). The elderly was more common in severe patients. The main clinical symptoms were fever (27/34)and dry cough(26/34). The peripheral blood showed normal or decreased leukocyte count (33/34), decreased lymphocyte count (12/34). The increase of C-reactive protein (CRP) and D-dimer was related to the severity of the disease. Some patients had mild liver and kidney damage. Six patients were diagnosed through 3 or more times of nucleic acid tests. Sixteen cases had Wuhan related history,13 cases were close contacts, 5 cases had no confirmed route. The clustered infections were found in 6 families. In typical cases, CT showed single or multiple patchy ground glass shadow with thickening of interlobular septum. In severe cases, diffuse lesions of both lungs were found, with ground glass shadow, consolidation shadow and strip shadow coexisting. Thirty-four patients were treated with interferon-α and Lopinavir/Ritonavir with good prognosis. Conclusions: The clinical characteristics of COVID-19 were similar to that of general viral pneumonia but with strong infectivity. Close contact and family aggregation caused disease outbreaks. COVID-19 could not be excluded if two nucleic acid tests were negative and high-resolution CT was helpful for differential diagnosis. Early detection, early isolation, early diagnosis and early treatment are important for good prognosis. The effectiveness of antiviral drugs needs to be further verified.

Abstract
Objective: To investigate the association between postprocedural D-dimer, high sensitivity C-reactive protein(hs-CRP) and low-density lipoprotein-cholesterol(LDL-C) and outcomes of acute myocardial infarction (AMI) patients treated by percutaneous coronary intervention(PCI), in order to clarify the impacts of thrombotic, inflammatory and cholesterol risks on long-term prognosis. Methods: Patients with AMI who underwent emergency PCI from January 2010 to June 2017 in Fuwai Hospital with complete baseline data were enrolled. Patients were stratified into four groups according to quartiles of D-dimer, hs-CRP and LCL-C. Cox regression was used to analyze the relationship between these biomarkers and prognosis. Restricted cubic spline (RCS) was used to characterize the continuous association between risk of all-cause death and biomarkers. The primary outcome was all-cause death. Results: A total of 3 614 patients were included in the analysis. The age was (59.2±12.0) years old, and 2 845 (78.7%) were male and 3 161 (87.5%) patients were diagnosed as ST-segment elevation myocardial infarction. The follow-up time was 652 (414, 1 880) days. Survival analysis showed that postprocedural D-dimer and hs-CRP were significantly associated with all-cause mortality (all P<0.05). Cox regression with multiple adjustments showed that patients with D-dimer≥580 μg/L presented higher risk of all-cause death (HR=2.03, 95%CI 1.22-3.38, P=0.006), compared to patients with D-dimer<220 μg/L. RCS analysis showed that risk of all-cause death was stably high when D-dimer reached 500 μg/L. Multivariable Cox regression also showed that patients with hs-CRP<2.74 mg/L (HR=1.86, 95%CI 1.10-3.15, P=0.020)or hs-CRP≥11.99 mg/L (HR=2.14, 95%CI 1.35-3.40, P=0.001) presented higher mortality compared to patients whose hs-CRP was 2.74-7.18 mg/L. RCS analysis indicated a J-shaped relation between hs-CRP and mortality, as greater risk of death was observed when hs-CRP was lower than 2 mg/L or higher than 10 mg/L. LDL-C was not associated with outcomes (all P>0.05). Conclusions: Postprocedural D-dimer is significantly associated with long-term prognosis of AMI patients treated by PCI. Patients with extremely high or low levels of hs-CRP presents worse outcomes. Intensive and tailored antithrombotic or anti-inflammatory therapies should be considered for patients with increased thrombotic risk and those with extremely high or low inflammatory risk.

Abstract
Expression of microRNA(miR)-142-3p has been implicated to be associated with several cancers, whereas its function in bladder cancer (BC) remains unknown. The present study aimed to explore the correlation between the expression of miR-142-3p and the proliferation, migration and invasion of bladder cancer cells by activating Rac1. qRT-PCR was used to measure the expression of miR-142- 3p in bladder cancer tissues and cell lines. RNA transfection was used to silence and accelerate the expression of miR-142-3p in bladder cancer cells. CCK-8 and trans-well assays were used to detect the proliferation, migration and invasion of cells before and after RNA transfection. The direct interaction between Rac1 and miR-142-3p was demonstrated by a dual luciferase reporter assay. qRT-PCR and Western blot assays were used to detect the expression changes in Rac1 before and after transfection. The results showed that miR-142-3p in bladder cancer tissues was significantly lower than that in adjacent tissues and lower than that in HT1376 and T-24 cells but higher than that in T5637 and BIU- 87 cells. Additionally, upregulating miR-142-3p expression not only inhibits the proliferation of SV-HUC-1 and BIU-87 cells but also inhibits migration and invasion, and downregulating miR-142-3p expression showed the opposite results. The expression of Rac1 was promoted after stimulating miR- 142-3p expression, but was inhibited after silencing miR-142-3p expression. In conclusion, miR-142-3p affects the proliferation, migration and invasion of bladder cancer cells by regulating Rac1.

Abstract
Objective: To compare the long-term outcomes in ST-elevation myocardial infarction (STEMI) patients who underwent early or late delayed percutaneous coronary intervention (PCI) using drug-eluting stents (DES). Methods: This study was a retrospective, observational and single-center study. Consecutive STEMI patients (n=977), who admitted to Fuwai Hospital in 2013 and underwent successful selective PCI using drug-eluting stents (DES) within 3 to 35 days after symptom onset were enrolled and divided into the early delayed PCI (3-14 d) group (n=495) and the late delayed PCI (15-35 d) group (n=482). General clinical data of the patients and related data of coronary angiography and interventional therapy were collected, and the endpoint events were followed up. The primary endpoint was 2-year major adverse cardiac and cerebrovascular events (MACCE) including cardiac death, recurrent myocardial infarction, definite or probable stent thrombosis and ischemic stroke. The secondary endpoint was 2-year ischemia-driven target vessel revascularization. The incidence of endpoint events of the two groups was compared, and it was compared again after the primary baseline characteristics such as age and gender were matched by the propensity scoring method at a 1∶1 ratio. Results: A total of 910 (93.1%) patients who underwent delayed PCI were transferred from other hospitals, and 292 (29.9%) patients received thrombolysis before PCI. The time interval before PCI was 14 (10, 20) days. The incidence of 2-year MACCE (3.0%(15/495) vs. 2.3%(11/482), P=0.468) and ischemia-driven target vessel revascularization (3.8%(19/495) vs. 5.0%(24/482), P=0.385) were similar between the two groups. The incidence of 2-year MACCE (3.3%(15/453 vs. 2.4%(11/453), P=0.426) and ischemia-driven target vessel revascularization (4.2% (19/453) vs. 4.9%(22/453), P=0.632) were also similar between the two groups after matching propensity score. Conclusion: The long-term clinical outcomes after early delayed PCI using DES is statistically equivalent to those of late delayed PCI using DES for STEMI patients who missed the time window for emergency PCI.

Abstract
BACKGROUND Wild apple, Malus sieversii, is an endangered species and a valuable genetic resource that requires a variety of conservation techniques. This study aimed to investigate the influence of different concentrations of hormones on wild apple regeneration from leaf and stem explants to establish an optimal regeneration system. RESULTS Leaves and stems derived from seedlings were cultured on several media supplemented with various concentrations of thidiazuron (TDZ) or 6-benzylaminopurine (BA) in different combinations with 1-naphthaleneacetic acid (NAA). The results showed that the most efficient shoot formation media (35% and 90%) were MS medium containing 4.0 mg L-1 TDZ and 1.0 mg L-1 NAA for leaf explants and MS medium containing 1.0 mg L-1 BA without NAA for stem explant. MS medium supplemented with 0.4 mg L-1 BA and 0.1 mg L-1 NAA (for shoot multiplication) and 1/2 MS + 0.1 mg L-1 NAA + 1.5% sucrose (for rooting) were effective media. Shoot regeneration from leaf explants was the most effective when the explants were placed abaxial side down onto the medium and were subjected to a pre-treatment of 3 weeks in darkness. CONCLUSIONS An optimized regeneration system for M. sieversii that allowed regeneration within 2-3 months developed. The protocol developed herein can be used in large-scale clonal propagation for the conservation of wild apple, M. sieversii.

Abstract
Production-theoretical decomposition analysis (PDA), built on production theory and data envelopment analysis, has been widely used to quantify the factors that drive CO2 emission changes to support policy analysis and making. Existing PDA methods are usually linked to Shephard distance function and Malmquist productivity index. However, decomposition results associated with these methods may be biased and incomplete. The challenges with these methods mainly stem from the problems associated with underestimating disaggregated efficiencies and the infeasibility of linear programming. This paper proposes a modified PDA approach based on a non-radial directional distance function and global Malmquist-Luenberger productivity index. This new approach addresses the problems associated with conventional PDA methods. To show the usefulness of the proposed approach, we apply it to study CO2 emissions in China and use the bootstrap method to test the statistical significance of the estimated results.

Abstract
Ultrafast reflection high-energy electron diffraction is employed to follow the lattice excitation of a Bi(111) surface upon irradiation with a femtosecond laser pulse. The thermal motion of the atoms is analyzed through the Debye–Waller effect. While the Bi bulk is heated on time scales of 2 to 4 ps, we observe that the excitation of vibrational motion of the surface atoms occurs much slower with a time constant of 12 ps. This transient nonequilibrium situation is attributed to the weak coupling between bulk and surface phonon modes which hampers the energy flow between the two subsystems. From the absence of a fast component in the transient diffraction intensity, it is in addition concluded that truncated bulk phonon modes are absent at the surface.

Abstract
Abstract
Objective
This study sought to depict the combined association of post-procedural cholesterol and inflammatory risk with clinical outcomes among acute myocardial infarction (AMI) patients undergoing percutaneous coronary intervention (PCI) and pick out patients with highest comprehensive risk.
Methods
A total of 4802 AMI-PCI patients were divided into quartiles according to post-procedural low-density lipoprotein cholesterol (LDL-C), C-reactive protein (CRP) level respectively and in combinations for risk analysis. Univariate and adjusted multivariate analysis with Cox model were performed. Hazard ratio (HR) for short-term (90 days) and long-term (1 year) were compared for major adverse cardiovascular events (MACE), including cardiac death, recurrent myocardial infarction and ischemic stroke.
Results
A significant change in the hazards of 90-day MACE was seen among patients in the highest quartile of post-procedural LDL-C [HR: 0.526 (0.291, 0.951), p=0.034] and highest quartile of CRP [HR: 2.119 (1.150, 3.920), p=0.016]. For 1-year outcomes, only a trend for increasing risk was seen in patients with higher post-procedural CRP (p-trend = 0.016). Combination analysis for cholesterol/inflammatory risk showed that patients lying simultaneously in the lowest quartile of LDL-C and highest quartile of CRP gained the highest risk in the 90-day [HR: 3.16 (1.124, 8.886), p=0.029] and 1-year [HR: 2.515 (1.153, 5.486), p=0.020] follow up.

Abstract
Congenital preauricular fistula can be sporadic or genetic. When inherited, it exhibits incomplete autosomal dominant genetic patterns. It can occur alone or with other diseases such as branchio-oto-renal syndrome. According to the position of fistula opening, congenital ear fistula can be divided into four categories: congenital preauricular fistula, congenital posterior ear fistula, congenital auricular fistula and congenital external auditory canal fistula. Congenital auricle fistula can be subdivided into congenital auricular fistula, congenital teal fistula, congenital earlobe fistula and so on. The diagnosis of preauricular fistula should be based on its clinical manifestation, and the diagnosis and treatment of special type of preauricular fistula should be emphasized. The treatment methods of congenital preauricular fistula include medicine, incision and surgical excision. According to the clinical practice of us and other scholars, surgical treatment is recommended in the period of acute infection, and the recurrence rate is not increased. The operation method of preauricular fistula, the application of microscope, dye tracer, probe and general anesthesia, and the clear surgical visualization are all helpful to reduce the recurrence rate.

Abstract
OBJECTIVE The purpose of this study was to determine the function of long non-coding RNA (LncRNA) ENST00000434223 (Lnc ENST) in renal carcinoma, and to explore the potential molecular mechanism. PATIENTS AND METHODS Quantitative Real-Time-Polymerase Chain Reaction (qRT-PCR) was used to detect the expressions of lncRNA ENST00000434223 and Wnt/β-catenin pathway-related mRNAs in tissues and cells of renal cancer. Chi-square test was performed to figure out the relationship between lncRNA ENST00000434223 and clinic-pathologic features of renal cancer patients. Besides, si-NC, si-ENST00000434223, pcDNA-NC and pcDNA-ENST00000434223 were transfected into renal cancer cells. The proliferative ability, metastasis and invasiveness of cells were detected using Cell Counting Kit-8 (CCK-8) and transwell assay, respectively. Lastly, the activation of the Wnt/hygro-catenin signal transduction pathway was evaluated by TOP/FOP Wnt Luciferase reporter assay and Western blot. RESULTS The expressions of Wnt2b and β-catenin were significantly increased in renal carcinoma, while E-cadherin was markedly down-regulated. Lowly expressed ENST00000434223 was involved in the poor prognosis of patients with renal cancer. In addition, down-regulating ENST00000434223 could enhance the viability, metastasis and invasiveness of renal cancer cells. However, overexpressing ENST00000434223 remarkably weakened the above cell functions. At the same time, interference or overexpression of ENST00000434223 could affect the expression level of proteins related to the Wnt/β-catenin signal pathway. CONCLUSIONS LncRNA ENST00000434223 inhibits the progression of renal cancer through the Wnt/shell-catenin signal pathway.

Abstract
Objective: To analyze the characteristics and patterns of occupational pneumoconiosis in Jiangsu Province, China, from 2006 to 2017, and to provide a scientific basis for government departments to develop effective interventions and preventive strategies against occupational pneumoconiosis. Methods: The data of 9327 patients with occupational pneumoconiosis were retrieved from the online report of occupational pneumoconiosis in Jiangsu Province from 2006 to 2017. Excel worksheet and SPSS 20.0 software were used to organize and analyze the data, respectively. An epidemiological statistical analysis was performed on age of onset, length of dust exposure, type of work, industry category, type of pneumoconiosis, annual incidence of pneumoconiosis, regional distribution, enterprise scale, and economic category in those patients. Results: A total of 9 327 patients with occupational pneumoconiosis were reported in Jiangsu Province from 2006 to 2017. In those patients, 8 559 were newly diagnosed and 768 had advanced disease. The male-female ratio was 16.34:1.Patients with stage I pneumoconiosis(6 994, 74.99%) were dominant in all the patients. The mean age of onset and length of dust exposure were 58.5±10.7 and 15.3±10.9 years, respectively. Most of the patients (6 012, 64.46%) had an age of onset between 50 and 69 years. For the length of dust exposure, the highest percentage was observed in patients exposed for no more than 5 years (2 231, 23.92%).The largest number of patients diagnosed with pneumoconiosis(1 200, 12.87%) was reported in 2010. Most of the patients(7 012, 75.18%) were from four cities, i.e, Wuxi (2 090, 22.41%), Yancheng (1 987, 21.30%), Suzhou (1 552, 16.64%), and Xuzhou (1 383, 14.83%). In all the patients, the incidence of silicosis (6791, 72.81%) was highest, followed by coal worker pneumoconiosis (1 364, 14.62%) and electric welder pneumoconiosis (563, 6.04%).Pneumoconiosis complicated by tuberculosis was found in 28 (0.3%) patients.A total of 1616 (17.33%) patients were reported in health, social security, and social welfare industries, while 1474 (15.80%) patients worked for coal mining and washing. Rock drillers (2 818, 30.21%) were dominant in those patients.State-owned economic enterprises reported the largest number of patients(5 441, 58.34%).Patients from small enterprises (4 323, 46.35%) had the highest percentage. Conclusion: Pneumoconiosis is an occupational disease with a high incidence in Jiangsu Province. Pneumoconiosis patients show an industry- and job-centered distribution. The length of dust exposure is decreasing.

Abstract
PURPOSE To explore the effects of mobile health (mHealth) intervention on pregnancy weight management, blood glucose control and pregnancy outcomes. METHODS A total of 124 patients with gestational diabetes mellitus (GDM) were selected. Patients were randomly divided into two groups. The 60 patients in the control group received standard outpatient treatment, while the remaining 64 patients received a nurse's online guidance both through a mobile medical App installed on their phone and through regular offline clinical treatment in the mHealth group. Patients were treated for an average of 13 weeks and general conditions, compliance, blood glucose, glycosylated hemoglobin, weight gain, pregnancy, and neonatal outcomes were monitored in both groups longitudinally. RESULTS The mHealth group demonstrated higher levels of compliance (83.3 ± 12.5% vs. 70.4 ± 10.1%, t = - 6.293, df = 122, p < 0.001), lower frequency of outpatient service (8.1 ± 1.3 vs. 11.2 ± 1.1, t = 14.285, df = 122, p < 0.001), lower hemoglobin A1C before delivery (4.7 ± 0.2 vs. 5.3 ± 0.3, t = 13.216, df = 122, p < 0.001) as well as the rates of off-target measurements both fasting (4.6 ± 0.4% vs. 8.3 ± 0.6%, t = 40.659, df = 122, p < 0.001) and 2 h post-prandial (7.9 ± 0.7% vs. 14.7 ± 0.8%, t = 50.746, df = 122, p < 0.001). Weight gain in the mHealth group was less than control group (3.2 ± 0.8 vs. 4.8 ± 0.7, t = 11.851, df = 122 p < 0.001). CONCLUSION Mobile health intervention management of gestational diabetes mellitus improves patients' compliance and blood glucose control, and reduces weight gain, thereby reducing the rates of complications in both pregnant women and fetuses during delivery during pregnancy.

Abstract
The purpose of this study was to compare the clinical effect of anterior cervical corpectomy with fusion vs laminoplasty for cervical ossification of the posterior longitudinal ligament. The outcome measures included the Japanese Orthopaedic Association score, neurological recovery rate, and complication rate. Subgroup A represented studies with the mean preoperative canal occupying ratio being less than 50%, whereas subgroup B represented studies with the mean canal occupying ratio being 50% or greater. In subgroup A, no difference was found between the 2 groups in the postoperative Japanese Orthopaedic Association score and neurological recovery rate. In subgroup B, the anterior cervical corpectomy with fusion group had a higher postoperative Japanese Orthopaedic Association score and neurological recovery rate. The authors recommend anterior cervical corpectomy with fusion for cervical ossification of the posterior longitudinal ligament when the canal occupying ratio is 50% or greater, and they prefer laminoplasty when the canal occupying ratio is less than 50%.

Abstract
The lattice response of a Bi(111) surface upon impulsive femtosecond laser excitation is studied with time-resolved reflection high-energy electron diffraction. We employ a Debye-Waller analysis at large momentum transfer of 9.3 Å-1 ≤ Δ k ≤ 21.8 Å-1 in order to study the lattice excitation dynamics of the Bi surface under conditions of weak optical excitation up to 2 mJ/cm2 incident pump fluence. The observed time constants τ int of decay of diffraction spot intensity depend on the momentum transfer Δk and range from 5 to 12 ps. This large variation of τ int is caused by the nonlinearity of the exponential function in the Debye-Waller factor and has to be taken into account for an intensity drop ΔI > 0.2. An analysis of more than 20 diffraction spots with a large variation in Δk gave a consistent value for the time constant τT of vibrational excitation of the surface lattice of 12 ± 1 ps independent on the excitation density. We found no evidence for a deviation from an isotropic Debye-Waller effect and conclude that the primary laser excitation leads to thermal lattice excitation, i.e., heating of the Bi surface.

Abstract
The aim of this study was to investigate the effects of dietary crude protein levels and cysteamine (CS) supplementation on meat quality and related indices in longissimus dorsi muscle of finishing pigs. One hundred and twenty barrows were randomly allocated to a 2 × 2 factorial arrangement with five replicates of six pigs each. The primary variations were crude protein levels (14% or 10%) and CS supplemental levels (0 or 140 mg kg−1). After 41 d, 10 pigs per treatment were slaughtered. The results showed that low-protein level diets (LPDs) decreased Warner–Bratzler shear force (P < 0.01) and increased the content of intramuscular fat (P < 0.01). The mRNA expressions of lipogenic genes were up-regulated (P < 0.01), and the mRNA expressions of lipolytic genes were down-regulated (P < 0.01) in pigs fed LPD. LPDs increased the mRNA expressions of μ-calpain, and decreased the mRNA expression of calpastatin (P < 0.01). In addition, CS supplementation increased the mRNA expression of μ-calpain (P < 0.01). In conclusion, LPD improved the meat quality probably through regulating the lipogenesis, lipolysis, and the proteolysis process in muscle. The CS supplementation did not affect the meat quality of finishing pigs. Moreover, no significant interaction between dietary protein levels and CS supplementation for the meat quality of finishing pigs was observed.

Abstract
Objective: To investigate the effects of proteasome beta 5 subunit (PSMB5) on proliferation and bortezomib (BTZ) chemo-sensitivity of multiple myeloma (MM) and its related molecular mechanisms. Methods: We used two MM cell lines, RPMI 8226 and BTZ drug-resistant cell line RPMI 8226/BTZ100 (hereinafter referred to as BTZ100) , as the research object. PSMB5 was overexpressed or knocked down in two myeloma cell lines via lentivirus transfection. CCK8 assay was used to detect the impact of PSMB5 on cell viability and bortezomib sensitivity in human myeloma cells; Using flow cytometry to test the effects of PSMB5 on apoptosis rate of human myeloma cells under the treatment of bortezomib; Apoptosis-related gene expression of Bax, Bcl-2, p-Akt and cleaved caspase-3 were detected by Western blot. Results: ①PSMB5 overexpression and knockdown were successfully constructed in RPMI 8226 and BTZ100 cells. ②PSMB5 expression was positively correlated with cell proliferation of RPMI 8226 and BTZ100 cells (P<0.05) . ③The cell viability was lower after PSMB5 knockdown in RPMI 8226 cells than control cells under the same concentration of BTZ[IC(50) at 24 h: (7.01±0.47) and (9.64±0.55) nmol/L respectively, t=6.289, P=0.003]. The cell viability was higher after PSMB5 overexpression in RPMI 8226 cells than control cells under the same concentration of BTZ[IC(50) at 24 h: (10.99±0.58) and (9.51±0.37) nmol/L respectively, t=3.724, P=0.020) . PSMB5 expression was negatively correlated with the sensitivity of RPMI 8226 cells to BTZ. The results of BTZ100 cells were similar. ④The expression of PSMB5 was negatively correlated with the apoptosis of RPMI 8226 and BTZ100 under the treatment of BTZ. ⑤Meanwhile, PSMB5 knockdown could increase the expression of pro-apoptosis gene Bax and cleaved caspase-3 and decrease the expression of anti-apoptotic gene Bcl-2 and p-Akt. PSMB5 over-expression has the opposite results. Conclusion: PSMB5 knockdown could improve the bortezomib sensitivity of MM cells via activation of apoptosis signaling. PSMB5 may be a potential therapeutic target for MM.

Abstract
AIMS To determine whether patients with painful myofascial temporomandibular disorders (TMD) demonstrate facilitated temporal summation (TS) responses to painful heat stimuli applied to the painful trigeminal and extratrigeminal regions and whether there is a side difference in the trigeminal region for myofascial TMD pain patients compared to healthy controls. METHODS Twenty female Chinese myofascial TMD pain patients and 20 age-matched female volunteers participated in this case-control study. Thermal detection thresholds, thermal pain thresholds, and TS of 20 repetitive noxious thermal stimuli were measured on the skin above the masseter muscle on both sides and the thenar eminence of the less painful side/dominant hand. Numeric rating scale (NRS) scores of pain were provided after the 1st, 5th, 10th, 15th, and 20th stimuli, and TS was calculated as the highest NRS score minus the first NRS score in each test. RESULTS Evidence of TS was found in the trigeminal and extratrigeminal regions for both groups, but with facilitated TS responses in myofascial TMD pain patients (P < .001). Within the myofascial TMD group and control group, there were no side-to-side differences (P > .289). Interestingly, the repetition of the TS test was associated with facilitated responses in myofascial TMD pain patients (P < .001). CONCLUSION The current findings suggest TS of painful heat stimulation is facilitated in myofascial TMD pain patients with no side difference in the trigeminal region.

Abstract
γ-MnO2, SmMnO3, and γ-MnO2/SmMnO3 catalysts were prepared by facile methods, wherein the SmMnO3 (SMO) perovskite was synthesized through one-step calcination and the γ-MnO2/SmMnO3 was formed by an in situ growth of γ-MnO2 on the surface of SMO. These materials ware characterized by XRD, SEM-mapping, N2-adsorption, XPS and H2-TPR to investigate their textural properties. Compared with that of SMO and γ-MnO2, the γ-MnO2/SMO shows better performance for catalytic oxidation of aromatic VOCs in wet air (10 vol.%), which may be attributed to its higher surface molar ratio of lattice oxygen to adsorbed oxygen (Olatt/Oads) and better low-temperature reducibility. Besides, for γ-MnO2/SMO catalyst, a successive oxidation route and the inner principle of BETX (benzene, ethylbenzene, toluene, and o-xylene) oxidation were also revealed via various tests and a comprehension of dynamics investigation. Meanwhile, the experiments under simulated realistic exhaust conditions displayed that the γ-MnO2/SmMnO3 is also a good catalyst with high stability for aromatic VOCs oxidation, and fulfilled endurability to high humidity (20 vol.%).
