Abstract
Objective: To compare the impact of orthodontic treatment on pulp volume in adolescents and adults. Methods: Cone-beam CT data of 62 patients undergoing orthodontic treatment at the Department of Orthodontics, Stomatological Hospital of Chongqing Medical University, from January 2019 to March 2022 were collected. Patients were divided into two age groups (31 patients in each group): adolescent group (aged 13-17, 17 males and 14 females) and adult group (aged 21-25, 12 males and 19 females). Pre-and post-treatment reconstructions of the pulp and dental tissues of upper first molars (UM1) and lower central incisors (L1) were performed. Measurements included pulp volume for UM1 (UM1 P) and L1 (L1 P), pulp chamber volume (UM1 PC) and root canal volume (UM1 RC) for UM1, root length for L1 (L1 RL), and mesiobuccal root length for UM1 (UM1 RL), as well as chamber heights at specific landmarks [the lengths from the central fossa fusion site to the roof of the pulp chamber (H1), the floor of the pulp chamber (H2), the nearest point of root divergence as well as crown-root bifurcation (H3), the farthest point of root divergence (H4), and the pulp chamber height (H5)] in UM1. Changes in these indices were calculated and analyzed using paired and independent sample t-tests for within-group and between-group differences, respectively. Pearson correlation was used to assess potential associations among H5, root length, and pulp volume changes. Results: Before and after orthodontic treatment, no significant difference was observed in the adult group for L1 P (t=-0.03, P=0.975), while significant differences were noted for UM1 P, UM1 PC, and UM1 RC (t=9.98, P<0.001; t=9.04, P<0.001; t=6.69, P<0.001). In the adolescent group, significant differences were found for both L1 P and UM1 P (t=2.25, P=0.029; t=6.30, P<0.001). After orthodontic treatment, the absolute value changes of UM1 P, UM1 PC, and L1 P in the adolescent group were (19.75±9.58), (15.07±7.65) and (1.89±6.29) mm3, respectively, and in the adult group were (13.33±9.41), (9.16±7.05) and (0.02±4.66) mm3, respectively (t=3.77, P<0.001; t=4.48, P<0.001; t=2.34, P=0.048). There was no significant absolute difference in the amount of UM1 RC between the two groups after orthodontic treatment (t=0.86, P=0.391). Before and after orthodontic treatment, the absolute value changes of L1 RL, H1 and H5 in the adolescent group were (0.54±0.41), (0.38±0.27) and (0.71±0.33) mm, respectively, and the absolute value changes in the adult group were (0.78±0.62), (0.26±0.20) and (0.57±0.28) mm, respectively (t=-2.43, P=0.017; t=2.96, P=0.004; t=2.57, P=0.011). Whereas no significant differences were observed for UM1 RL, H2, H3, and H4 (t=-0.85, P=0.400; t=0.43, P=0.669; t=-0.50, P=0.619; t=1.46, P=0.148). Additionally, significant correlations were found between changes in H5 and UM1 RL with UM1 P (r=0.35, P<0.001; r=0.19, P=0.030), but not between Changes in L1 RL and L1 P (r=0.11, P>0.05). Conclusions: The effect of orthodontic treatment on pulp volume in adolescents and adults were different.

Abstract
Objective: By identifying different metabolites in the serum and clarifying the potential metabolic disorder pathways in metabolic syndrome (MS) and stable coronary artery disease patients, to evaluate the predictive value of specific metabolites based on serum metabolomics for the occurrence of MS and coronary heart disease in overweight or obese populations. Methods: This is a retrospective cross-sectional study. Patients with Metabolic Syndrome (MS group), patients with stable coronary heart disease (coronary heart disease group), and overweight or obese individuals (control group) recruited from the Central District of the First Affiliated Hospital of Zhengzhou University from 2017 to 2019 were assigned to the training set, meanwhile, the corresponding three groups of people recruited from the East District of the hospital during the same period were assigned to the validation test. The serum metabolomics profiles were determined by ultra-performance liquid chromatography-quadrupole/orbitrap high-resolution mass spectrometry (UHPLC-Q-Orbitrap HRMS). Clinical characteristics (age, gender, body mass index (BMI), blood pressure, fasting plasma glucose (FPG), glycosylated hemoglobin (HbA1c), alanine aminotransferase (ALT), aspartate transaminase (AST), total cholesterol (TC), triacylglycerol (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), glomerular filtration rate (eGFR), creatinine (CR)) were also collected. Based on the orthogonal partial least-squares discrimination analysis (OPLS-DA) model, the significantly changed metabolites for MS and coronary artery disease patients were screened according to variable important in projection (VIP), and the receiver operating characteristic (ROC) analysis was evaluated for the risk prediction values of changed metabolites. Results: A total of 488 subjects were recruited in this study, the training set included 40 MS, 249 coronary artery disease patients and 148 controls, the validation set included 16 MS, 18 coronary artery disease patients and 17 controls. We made comparisons of the serum metabolites of coronary artery disease vs. controls, MS vs. controls, and coronary artery disease vs. MS, and a total of 22 different metabolites were identified. The disturbed metabolic pathways involved were phospholipid metabolism, amino acid metabolism, purine metabolism and other pathways. Through cross-comparisons, we identified 2 specific metabolites for MS (phosphatidylcholine (18∶1(9Z)e/20) and pipecolic acid), 4 specific metabolites for coronary artery disease (lysophosphatidylcholine (17∶0), PC(16∶0/16∶0), hypoxanthine and histidine), and 4 common metabolites both for MS and coronary artery disease (isoleucine, phenylalanine, glutathione and LysoPC(14∶0)). Based on the cut-off values from ROC curve, the predictive value of the above metabolites for the occurrence of MS in overweight or obese populations is 100%, the predictive value for the occurrence of coronary heart disease is 87.5%, and the risk predictive value for coronary heart disease in MS patients is 82.1%. Conclusions: The altered serum metabolites suggest that MS and coronary heart disease may involve multiple metabolic pathway disorders. Specific metabolites based on serum metabolomics have good predictive value for the occurrence of MS and coronary heart disease in overweight or obese populations.

Abstract
Natural killer (NK) cells play significant roles in spontaneous antitumor response in multiple cancers, including gastric cancer. Currently, lncRNAs were identified as essential modulators in the development of NK cells via competing for the target miRNA. However, the regulatory mechanism of GAS5 in NK cells remains largely elusive. The expressions of GAS5 and miR-18a in NK cells were measured by qRT-PCR. The killing effects of NK cells were conducted by lactate dehydrogenase (LDH) assay. Detection of IFN-γ and TNF-α level was carried out using ELISA assay. The interaction between GAS5 and miR-18a was determined by the luciferase reporter system and RIP assay, respectively. We found that GAS5 expression was downregulated while miR-18a expression was upregulated in primary NK cells isolated from GC patient compared with the healthy controls. Moreover, activation of NK cells stimulated by IL-2 enhanced the secretion of IFN-γ, TNF-α, and the expression of GAS5. The deficiency of GAS5 significantly suppressed the secretion of IFN-γ and TNF-α as well as the killing effect of NK cells. Subsequently, luciferase reporter and RIP assay confirmed the interaction between GAS5 and miR-18a. In addition, miR-18a inhibitor attenuated GAS5 silencing induced inhibition of the cytotoxicity of activated NK cells. In conclusion, GAS5 promotes the killing effect of the natural killer cells against GC by regulating miR-18a, providing promising strategies for NK cells based antitumor therapies.

Abstract
Objective: To investigate the mechanical effects during en-mass retraction of maxillary anterior teeth with clear aligner using three-dimensional finite element method. Methods: Cone-beam CT (CBCT) was used to scan a female orthodontic patient (26 years old, from Department of Orthodontics, Stomatological Hospital of Chongqing Medical University) whose maxillary first premolars were extracted and maxillary dentition had been aligned and leveled. A finite element model including maxillary teeth-periodontal ligament (PDL)-alveolar bone-clear aligner was established by using Mimics 17.0, SolidWorks 2016 and Geomagic Studio 2015 software packages. The process of 0.2 mm en-mass retraction of anterior teeth using clear aligner was simulated by using non-linear contact method of Abaqus 6.14. The trend and displacement of maxillary teeth, the stress distribution of PDL and alveolar fossae, and the deformation trend of clear aligner were obtained and analyzed. Results: Under the experimental condition, lingual crown tipping and distal tipping movement of anterior teeth were observed, and all of them had the tendency of overbite increasing.The maximum displacement of the central incisor, lateral incisor and canine were 25.16, 50.34 and 24.98 μm, respectively. Meanwhile, the second premolar, first molar and second molar had the tendency of mesial tipping movement, and the maximum displacement of them were 33.04, 2.90 and 16.63 μm, respectively. The stress distribution both at the PDL and alveolar fossae were consistent with tooth movement pattern. It was noted that the stress in the PDL of the canine and second premolar were comparatively big, and the corresponding apical areas of alveolar fossae appeared stress concentration. Concurrently, it was found that the clear aligner showed stress concentration at the junction of adjacent teeth with a tendency of crown directional dislocation. Conclusions: During en-mass retraction of anterior teeth with clear aligner, attention should be paid to the overbite and torque in anterior teeth, and the anchorage protection of posterior teeth. At the same time, we should be careful of root resorption of the teeth on both sides of the extraction space.

Abstract
Objective: To investigate bone remodeling in patients with different types of juvenile condylar resorption after stabilization splint treatment using cone-beam CT (CBCT). Methods: Fifty-nine juvenile condylar resorption patients (114 sides of condyle) treated with stabilization splint from January 2012 to May 2018 in Department of Temporomandibular Joint, Stomatological Hospital of Chongqing Medical University were selected as splint group, while twenty-four patients (48 sides of condyle) who underwent natural remodeling without stabilization splint treatment after 6-12 months were severed as control group. Pre-and post-treatment CBCT was taken for all patients. There were three types of condyles (including type Ⅰ, type Ⅱ and type Ⅲ) before treatment and four types of condyles (including progression, no changes, stable without new bone and remodeled with new bone) after treatment. Progression and no change were considered as poor curative effect, and stable without new bone and remodeled with new bone were considered to be effective. The vertical distance of the condylar height was measured and compared before and after treatment in the two groups. Results: Significant difference in treatment outcome was found in types Ⅰ and Ⅱ between the splint group and the control group (Z=-2.874, P=0.004; Z=-3.874, P=0.000), and no significant difference was found in type Ⅲ between the two groups (Z=-0.617, P=0.537). The difference of condylar progression percentage [splint group: 43% (15/35), control group: 80% (16/20)] was statistically significant between the two groups in type Ⅱ (χ(2)=7.139, P=0.011), and no significant difference was found in types Ⅰ and Ⅲ between the two groups (χ(2)=0.103, P=0.748; χ(2)=1.249, P=0.540). In two groups, the condylar height difference before and after treatment in type Ⅱ condylar resorption was statistically significant (P<0.05). Conclusions: Stabilization splint treatment was effective in patients with different types of juvenile condylar resorption, especially in type Ⅰ. However, it was difficult to reverse the height reduction of the condylar bone regardless of treatment.

Abstract
Objective: To investigate the thickness of cranial bone in different parts of children skull during stereotactic electroencephalogram (SEEG) and its effect on electrode fixation. Methods: From October 2016 to March 2017, 13 children with SEEG by robot of surgery assistant (ROSA) were selected. The basic case information and electrode design scheme were collected. The skull thickness of each electrode channel was measured on post-operation CT, and the loosening of the fixed screws were recorded. The thickness of skull in frontal bone, temporal bone, parietal bone and occipital bone was statistically processed by SPSS statistical software. Results: There were total 113 electrodes in 13 children with epilepsy. There were 45 electrodes at frontal bone, of which the thickness was (5.7±2.8)mm. There were 34 electrodes at temporal bone, of which the thickness was (3.5±1.3)mm.There were 16 electrodes at parietal bone, of which the thickness was (6.0±2.5)mm.There were 18 electrodes at occipital bone, of which the thickness was (6.9±0.5)mm. Statistics showed that there was significant difference between differnt bone (F=15.340, P<0.01). There were 4 electrodes loosening, 1 at frontal bone and 3 at temporal bone, when the screws were removed. There was no adverse event related to the implantation of electrodes. Conclusions: The children's skull thickness is thinner than adults. The screw loosening is exist in some cases, but it has no effect on SEEG recording. No SEEG related adverse events are found in this group. Therefore, ROSA guided SEEG is safe and reliable in children with epilepsy.

Abstract
Diphyllobothrium latum infection in human is not common in China and only 15 cases have been reported since 1927. We document a case of Diphyllobothrium latum infection caused by the ingestion of raw fish in a 23-year-old woman in Dalian (Liaoning Province), and diphyllobothriasis latum in China is briefly reviewed. The patient experienced abdominal discomfort for about 6 months with a history of discharging proglottids in the feces. The morphologic characteristic of the gravid proglottids and eggs were identified as that of Diphyllobothrium latum. The patient was treated with pumpkin seed powder (100g) and betel nut(100g) on an empty stomach. The majority of reported human cases occurred due to the ingestion of raw or uncooked fish, such as pikes, burbots, trouts, perch and salmons. The patient is the first case reported in Dalian (Lianning Province).

Methods: The clinical data of one Chinese pedigree of PHO, namely pachydermoperiostosis (PDP) were collected.Blood samples were drawn from the propositus and other family members.DNA was extracted and genetic analysis was performed by Sanger method after PCR.The sequencing data of HPGD gene exons were analyzed by alignment with sequences from National Center for Biotechnology Information (NCBI). Results: (1)The propositus represented symptoms in childhood including clubbing fingers, sweating, seborrhea, joint swelling and so on.Periosteal thickening and bone hyperplasia were found by X-ray. (2)The homozygous mutation named c. 310_311delCT in propositus, which located in the third exon of HPGD, was identified.His parents carried the same heterozygous mutation, while his sister did not inherit any mutation of this gene. (3)The prediction of spatial structure of proteins revealed that the mutant proteins had about 60% discrepancy compared with wild-type protein, losing a lot of motifs responsible for combining with coenzyms and prostaglandin E(2), as well as active sites of enzymes. Conclusions: The clinical manifestations and imaging findings are helpful to diagnose PDP. Moreover gene mutation analysis ensures the diagnosis.The structure and function of HPGD gene mutation induce 15-hydroxy prostaglandin dehydrogenase mutation, contributing to the occurrence of PDP.

Abstract
OBJECTIVE To analyze the mammographic, MRI, and clinicopathological characteristics of primary breast lymphoma (PBL). METHODS Clinicopathological characteristics were retrospectively reviewed and analyzed in 32 patients with histopathologically proven PBL. All cases were female (mean age, 50 years; median age 46 years; range, 30-68 years). RESULTS In the 32 cases, there were bilateral tumors in 5 cases and 27 cases of unilateral involvement. The patients presented with a painless mass in 25 cases and with pain in 7 cases. Rapid enlargement was observed in 6 cases. Mammograms of 17 tumors showed a round, circumscribed mass with high density or iso-density in 9, asymmetry in 7 and no abnormality was found in one. 37 lesions were detected on dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) in 29 patients, among which 25 (67.6%) lesions appeared as enhancing masses and 12 (32.4%) lesions as non-mass enhancements. All lesions showed iso- or hypo-intense signal on the T1WI and hyper-intense signal on the T2W1. Analysis of the enhancing masses based on the 2013 ACR BI-RADS lexicon revealed that among the mass descriptors in 25 lesions, the most common features were circumscribed or irregular margin in 24 (96.0%) and homogeneous internal pattern in 19 (76.0%). Of the 12 non-mass enhancing lesions, the most common descriptors included regional or multiple regional distribution in 6 (50.0%), and heterogeneous internal pattern in 8 (66.7%). The tumors showed early enhancement with penetrating vessels on DCE-MRI in 16 lesions, associated with skin thickening in 14, and axillary lymphadenopathy in 19. The time-signal intensity curve (TIC) in 14 patients was mainly of type Ⅲ (7/14, 50.0%). CONCLUSIONS Some imaging features may alert the diagnosis of primary breast lymphoma, but final diagnosis depends on histopathology. Early diagnosis is helpful for selecting appropriate treatment regimens.

Abstract
CBL-interacting protein kinases (CIPKs) mediate many plant responses to abiotic stress. However, their functions are poorly understood in halophytes. In this study, we isolated a CIPK gene, NtCIPK2, from the halophyte Nitraria tangutorum. By sequence alignment and the construction of a phylogenetic tree, we found that NtCIPK2 is similar to CIPK2 proteins from other plants, and contains conserved domains and motifs. The promoter of NtCIPK2 harbors many cis-acting elements that might be recognized and bound by transcription factors that are related to hormones and stress responses. NtCIPK2 was ubiquitously and robustly expressed in all tested organs, and was induced by salinity, drought, heat, and cold stress. The overexpression of NtCIPK2 in Escherichia coli caused better growth against high salinity, alkalinity, and osmotic conditions, dehydration, and extreme temperatures (i.e., heat and cold) compared to the control. Thus, NtCIPK2 is a candidate gene that might improve the stress tolerance of crops and herbs through genetic manipulation.

Abstract
The function of spontaneous T suppressor cell (STs) of peripheral blood was examined in 56 patients with schistosomiasis japonica at various stages. The subsets of T cell were simultaneously phenotyped in 46 cases. The percentages of CD3+ (pan T cell), CD4+ (helper/inducer T cell) and CD8+ (suppressor/cytotoxic T cell) in patients with acute schistosomiasis japonica were significantly higher than those in the normal controls. In patients with chronic and advanced schistosomiasis japonica, the percentage of CD8+ T cell and the function of STs were greatly increased, but the percentage of CD3+ T cell and the ratio of CD4+/CD8+ were obviously reduced. All of these markers changed more significantly in patients with advanced schistosomiasis japonica. The percentage of CD8+ T cell in patients with acute schistosomiasis japonica was negatively correlated with the function of STs. In patients with chronic and advanced schistosomiasis japonica the percentage of CD8+ T cell was correlated positively and the ratio of CD4+/CD8+ negatively with the function of STs. The results indicated that the cellular immunity was significantly increased in cases of acute schistosomiasis japonica and decreased in those with chronic or advanced schistosomiasis japonica. The increased CD8+ T cell may be principally cytotoxic T cells in patients with acute schistosomiasis japonica, but suppressor T cells in patients with chronic and advanced schistosomiasis japonica. The subsets of T cells and the function of T suppressor cells may play an important role in the immunoregulation of schistosomiasis japonica.

Abstract
In liver biopsies from 21 patients with schistosomiasis japonica complicated by hepatocellular carcinoma (HCC), 69 patients with advanced schistosomiasis japonica, and 25 patients with HCC, HBsAg and HBcAg were investigated with peroxidase-antiperoxidase technique. The positive rate of HBAg (i.e. HBsAg and/or HBcAg) in the liver of patients with schistosomiasis japonica complicated by HCC was significantly higher than in the group of advanced schistosomiasis japonica, but similar to that in cases of HCC. The location of carcinoma cells in the liver was not related to the distribution of Schistosoma ova in patients with schistosomiasis japonica complicated by HCC. The results indicated that the complication with hepatitis B virus infection may be one of the major factors involved in the development of HCC in patients with schistosomiasis japonica.
