Biomechanical effects of a mandibular advancement device on the periodontal ligament: Based on different bone models.

Obstructive sleep apnea syndrome (OSAS) is recurrent apnoea caused by upper airway obstruction during sleep. In severe cases, OSAS might lead to sudden death. Currently, the mandibular advancement device (MAD) is the preferred product for the treatment of mild to moderate OSAS because of its compliance, portability and low cost. However, many clinical studies have suggested that long-term use of MAD might cause occlusal changes, periodontitis, muscle soreness, and joint damage. In view of the difficulties in the measurement of relevant mechanical factors in vivo, the present work aimed to quantitatively analyze biomechanical mechanisms that might lead to these side effects through computer numerical simulations and a nonhomogeneous alveolar bone model was established to approximate the actual bony features of the jaw in the simulations model. First, a 3D digital model of the teeth, periodontal ligament(PDL), and alveolar bone was created on the basis of computed tomography images and assembled with a 3D model of the MAD. A nonhomogeneous alveolar bone model was created based on computed tomographic images, and the stresses acting on the PDL were computed using the finite element method. The results showed that the nonhomogeneous model could more realistically reflect the mechanical properties of the alveolar bone and obtain the true stresses compared with the homogeneous model, which underestimated the adverse effects of PDL therapy. The numerical simulations in this paper can help doctors make more accurate judgements about MAD treatment from an oral health protection perspective.

Analysis of Intervention of Erxiantang in Ovariectomized Rats by LC-MS Serum Metabolomics / 中国实验方剂学杂志

ObjectiveTo investigate the changes of endogenous metabolites in serum of ovariectomized rats and the effect of Erxiantang on them based on liquid chromatography-mass spectrometry（LC-MS）. MethodTwenty-four healthy female SD rats were randomly divided into sham-operated group， model group and Erxiantang group（7.5 g·kg-1）， with 8 rats in each group. Bilateral ovarian tissues were excised in the model and Erxiantang groups， and small pieces of adipose tissues were excised in the abdominal cavity of the sham-operated group bilaterally， and gastric administration was started 2 weeks after surgery， and equal volumes of distilled water were gavaged in the sham-operated and model groups. After 12 weeks of administration， blood was collected from abdominal aorta， and non-targeted metabonomics was performed on rat serum by LC-MS， and orthogonal partial least squares-discriminant analysis（OPLS-DA） was used to screen differential metabolites. Metabolic pathway analysis was performed based on Kyoto Encyclopedia of Genes and Genomes（KEGG）， and the levels of key enzymes of metabolic pathways were verified by enzyme-linked immunosorbent assay（ELISA）. ResultThe results of metabonomics showed that 82 differential metabolites between the model group and the sham-operated group were glycerophospholipids， fatty acyls， steroids and steroid derivatives， of which the most significant difference was glycerophospholipids. At the same time， Erxiantang could call back 65 out of 82 differential metabolites， of which 11 were statistically significant， mainly phosphatidylcholine（PC） and lysophosphatidylcholine（LysoPC） in glycerophospholipids， followed by corticosterone and 11-deoxycortisol in steroids and steroid derivatives. Metabolic pathway analysis showed that the pathways of glycerophospholipid metabolism and steroid hormone biosynthesis in model group were changed， and were recovered after the administration of Erxiantang. ELISA results showed that compared with the sham-operated group， serum levels of cholinephosphate cytidylytransferase（CCT）， secretory phospholipase A2（sPLA2） and lysophosphatidylcholine acyltransferase（LPCAT）， which were the key metabolic enzymes of glycerophospholipid metabolite PC and LysoPC， were significantly decreased in the model group（P<0.05， P<0.01）， and choline phosphotransferase 1（CPT1） levels decreased but the difference was not statistically significant， compared with the model group， the levels of CCT， sPLA2 and CPT1 were significantly increased in Erxiantang group（P<0.01）. In addition， compared with the sham-operated group， the levels of cholesterol（TC）， triglyceride（TG） and low density lipoprotein cholesterol（LDL-C） were significantly increased in the model group（P<0.01）， the high density lipoprotein cholesterol（HDL-C） level was decreased（P<0.05）， compared with the model group， the levels of TC， TG and LDL-C were significantly decreased and the level of HDL-C was significantly increased in Erxiantang group（P<0.01）. ConclusionEndogenous metabolites and related metabolic pathways in ovariectomized rats were altered， and Erxiantang can reverse some of the different metabolites and related pathways， such as regulating glycerophospholipid metabolism by regulating metabolic enzymes CCT， sPLA2 and CPT1 to increase the levels of PC and LysoPC， and then improve the pathological changes such as lipid metabolism disorder in ovariectomized rats.

Human 8-cell embryos enable efficient induction of disease-preventive mutations without off-target effect by cytosine base editor

Approximately 140 million people worldwide are homozygous carriers of APOE4 (ε4), a strong genetic risk factor for late onset familial and sporadic Alzheimer's disease (AD), 91% of whom will develop AD at earlier age than heterozygous carriers and noncarriers. Susceptibility to AD could be reduced by targeted editing of APOE4, but a technical basis for controlling the off-target effects of base editors is necessary to develop low-risk personalized gene therapies. Here, we first screened eight cytosine base editor variants at four injection stages (from 1- to 8-cell stage), and found that FNLS-YE1 variant in 8-cell embryos achieved the comparable base conversion rate (up to 100%) with the lowest bystander effects. In particular, 80% of AD-susceptible ε4 allele copies were converted to the AD-neutral ε3 allele in human ε4-carrying embryos. Stringent control measures combined with targeted deep sequencing, whole genome sequencing, and RNA sequencing showed no DNA or RNA off-target events in FNLS-YE1-treated human embryos or their derived stem cells. Furthermore, base editing with FNLS-YE1 showed no effects on embryo development to the blastocyst stage. Finally, we also demonstrated FNLS-YE1 could introduce known protective variants in human embryos to potentially reduce human susceptivity to systemic lupus erythematosus and familial hypercholesterolemia. Our study therefore suggests that base editing with FNLS-YE1 can efficiently and safely introduce known preventive variants in 8-cell human embryos, a potential approach for reducing human susceptibility to AD or other genetic diseases.

NF-κB-Activated lncRNACASC9 Promotes Bladder Cancer Progression by Regulating the TK1 Expression.

Long noncoding RNAs (lncRNA) are involved in cancer development, but the roles of most lncRNAs are undocumented. In this study, we identified lncRNAs that were abnormally expressed in bladder cancer. We found that lncRNACASC9 plays an important role in the progression of bladder cancer. CASC9 was highly expressed in bladder cancer cells and tissues, and the prognosis of bladder cancer patients with high expression of CASC9 was poor. The results of colony formation assays, CCK-8 assays, EdU assays, transwell assays, mouse xenograft models, and tail vein injection lung metastasis model showed that CASC9 could promote bladder cancer cells growth and metastasis both in vitro and in vivo. Mechanistically, through FISH experiments, luciferase reporter experiments, and RIP experiments, we proved that CASC9 regulated the expression of TK1 by adsorbing miR-195-5p, thereby exerting an oncogenic effect in bladder cancer. Taken together, our findings support that the CASC9/miR-195-5p/TK1 axis is a critical pathway in the tumorigenesis and progression of bladder cancer, implicating a new therapeutic direction for the treatment of bladder cancer.

【Objective】 To study the yielding rate and distribution of unexpected antibodies in blood transfusion children with thalassemia in Yunnan province, and to explore the blood transfusion strategies. 【Methods】 From January 2016 to December 2021, 298 children with thalassemia, who received blood transfusion treatment in Kunming, Xishuangbanna, Wenshan, Dehong, Yuxi and Baoshan hospitals across Yunnan Province, were selected. The unexpected antibodies of blood plasma were screened by microcolumn gel card. The samples with positive antibodies were identified for alloantibody specificity. 【Results】 Unexpected antibodies were yielded in 67 out of 298(22.48%) transfused children with thalassemia. The positive rates of unexpected antibodies in boys and girls were 16.55%(24/145) and 28.10%(43/153), respectively. The positive rates of unexpected antibodies in Han, Dai, Zhuang, Yi, Bulang, Jinuo and Miao people were 14.06%(18/128), 30.80%(32/104), 35.71%(10/28), 36.36%(8/22), 50.00%(4/8), 60.00%(3/5)and 66.67%(2/3), respectively, with statistically significant differences between each other. The positive rate of unexpected antibodies in ethnic minorities was higher than that in Han. The positive rates of unexpected antibodies in children who received the first transfusion at birth-one year old, 1~3 years old, 3~6 years old and above 6 years old were 12.50%(3/24), 10.14%(7/69), 24.54%(40/163)and 40.48%(17/42), respectively. The positive rates of unexpected antibodies in children with first transfusion after 3 years old were significantly higher than those before 3 years old. The positive rates of unexpected antibodies in children with one transfusion, 1~3, 3~10, 10~20 and more than 20 transfusions were 4.76%(1/21), 12.07%(7/58), 23.71%(23/97), 28.16%(29/103)and 36.84%(7/19), respectively, with statistically significant differences between each other. The number of blood transfusions was positively correlated with the unexpected antibody yielding. The yielding rate of unexpected antibodies in children with α thalassemia, βthalassemia, δ+ βthalassemia and untyped thalassemia was 7.50%(3/40), 17.62%(34/193), 53.70%(29/54)and 9.09%(1/11), respectively(P<0.05). The yielding rate of unexpected antibodies in transfused children with δ+ βthalassemia was the highest. And 57 unexpected antibodies of Rh blood group system were yielded, 6 anti-M antibodies, 2 anti-N antibodies and 2 undetermined. 【Conclusion】 The positive rate of unexpected antibodies in transfused children with thalassemia in Yunnan province is high. Routine antibody screening should be carried out for transfusion children with thalassemia, and blood units, compatible with ABO, Rh and MNS typing results, should be selected to ensure the safety and effectiveness of clinical blood use.

Luminescence intensity ratio thermometry based on combined ground and excited states absorptions of Tb3+ doped CaWO4.

Luminescence intensity ratio (LIR) thermometry is of great interest, because of its wide applications of noninvasive temperature sensing. Here, a LIR thermometry based on combined ground and excited states absorptions is developed using CaWO4:Tb3+. The ratio of single luminescence (5D4-7F5) intensities under 379 and 413 nm excitations with opposite temperature dependences, attributed to the thermal coupling of ground state 7F6 and excited state 7F5, is used to measure temperature. This LIR method achieves a high relative sensitivity of 2.8% K-1, and can avoid complex spectral splitting by collecting all down-shifting luminescence bands, being a promising accurate luminescence thermometry.

Optimal fluorescence and photosensitivity properties of dual-functional NaYb1-x F4:Tm x 3+ nanoparticles for applications in imaging guided photodynamic therapy.

The fluorescence and photosensitivity properties of NaYb1-x F4:Tm x 3+ nanoparticles were optimized to develop noninvasive near-infrared fluorescence imaging-guided photodynamic therapy. The emission at 800 nm from Tm3+ presented an exponential increase with an increase in the Tm3+ doping concentration from 0 to 2%. The photosensitivity properties of NaYb1-x F4:Tm x 3+ nanoparticles were also studied via the chemoprobe method, which used a reactive oxygen quencher, 1,3-diphenylisobenzofuran (DPBF). With the increase in the doping concentration of Tm3+, the generation rate of reactive oxygen species in NaYb1-x F4:Tm x 3+ nanoparticles decreased linearly at a rate of 0.3. The doping concentration of Tm3+ had two opposite effects on the 800 nm emission and generation rates of reactive oxygen species. The competitive relationship was discussed and an optimal value for the Tm3+ doping concentration of approximately 1% was determined. At this concentration, the energy of the Yb3+ excited state can be fully utilized, and the fluorescence and photosensitivity properties are an effective combination.

Sex Differences in Physiological Stress Induced by a Long-Lasting Adventure Race: A Prospective Observational Analytical Study.

BACKGROUND: In order to provide additional information on the behaviour of biochemical parameters related to stress responses to a specific long-term competition, we aimed to compare the stressful effects of a long-lasting competition on physiological variables in men and women. METHODS: This is a prospective observational analytical study. Twenty-five professional athletes, 15 men and 10 women, travelled 460 km for 4 days in an international edition of the Ecomotion/Pro AR World. RESULTS: After the competition, we detected an increase in α-amylase and cortisol levels and a decrease in salivary immunoglobulin A (lgA) levels. The relative percentage changes in α-amylase, IgA and cortisol levels were significantly higher in women than in men, whereas women had lower relative percentage changes in glucose and lactate levels compared with men. There was a decrease in lymphocyte, eosinophil and monocyte counts, with relative percentage decreases in lymphocytes and monocytes being significantly higher in female athletes than in males. There were increases in the serum activities of total creatine kinase (CK), the creatine kinase myocardial isoform (CKMB), alanine aminotransferase (ALT), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) at the end of the test, with significantly higher elevations of total CK, CKMB and LDH in men and ALT in women. CONCLUSION: Long-lasting competition induced stress, muscle damage, anaemia and changes in the immune system. Women had more intense responses of cortisol and leukocytes.

Ubiquitinome Profiling Reveals the Landscape of Ubiquitination Regulation in Rice Young Panicles / 基因组蛋白质组与生物信息学报·英文版

Ubiquitination, an essential post-transcriptional modification (PTM), plays a vital role in nearly every biological process, including development and growth. Despite its functions in plant reproductive development, its targets in rice panicles remain unclear. In this study, we used proteome-wide profiling of lysine ubiquitination in rice (O. sativa ssp. indica) young panicles. We created the largest ubiquitinome dataset in rice to date, identifying 1638 lysine ubiquitination sites on 916 unique proteins. We detected three conserved ubiquitination motifs, noting that acidic glutamic acid (E) and aspartic acid (D) were most frequently present around ubiquitinated lysine. Enrichment analysis of Gene Ontology (GO) annotations and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways of these ubiquitinated proteins revealed that ubiquitination plays an important role in fundamental cellular processes in rice young panicles. Interestingly, enrichment analysis of protein domains indicated that ubiquitination was enriched on a variety of receptor-like kinases and cytoplasmic tyrosine and serine-threonine kinases. Furthermore, we analyzed the crosstalk between ubiquitination, acetylation, and succinylation, and constructed a potential protein interaction network within our rice ubiquitinome. Moreover, we identified ubiquitinated proteins related to pollen and grain development, indicating that ubiquitination may play a critical role in the physiological functions in young panicles. Taken together, we reported the most comprehensive lysine ubiquitinome in rice so far, and used it to reveal the functional role of lysine ubiquitination in rice young panicles.

Research progress of leptin resistance mechanism / 中华内分泌代谢杂志

With the progress of society and the improvement of living standard, the incidence of obesity is increasing. Serum leptin level increased significantly in the obese patients with hyperinsulinemia. However, the response to leptin is weakened, and then " leptin resistance" is widely concerned. Previous studies have focused on serum leptin levels and leptin receptor expression. In recent years, the mechanism of leptin resistance has been elucidated from different perspectives. This article tries to review the recent progress in the mechanism for leptin resistance, and briefly discusses the relationship between leptin resistance and insulin resistance, as well as the latest treatment measures for leptin resistance. With the development of leptin resistance research, it is believed that the increasing leptin sensitivity will be an important measure in obesity treatment.

Objective:To investigate the effect of 125I-RSOAds-hTERT/PSA oncolytic adenovirus on targeted therapy of prostate cancer and its effect on tumor microenvironment. Methods:125I-RSOAds-hTERT/PSA ( 125I-virus complex) oncolytic adenovirus was constructed by PCR amplification and double restriction enzyme ligation. TUNEL staining, flow cytometry and Caspase-3 immunoblotting assay were used to detect the killing effect of 125I-RSOAds-hTERT/PSA oncolytic adenovirus on prostate cancer cells in vitro and in vivo, respectively. To explore the effect of 125I-virus complex on tumor tissue cytokine secretion levels, interleukin 2 (IL-2), IL-10, tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ) in the culture supernatant of human prostate cancer cell line PC3, mouse prostate adenocarcinoma cell line RM-1, and mice serum were detected by ELISA. We explored the regulation of 125I-virus complex on the expression of CD24, CD44 and prostate stem cell antigen (PSCA) in prostate tumor tissues and tumor cells through immunohistochemistry. Meanwhile, the expression levels of CD32 and vascular endothelial growth factor (VEGF), as well as CD4+ , CD8+ and macrophage infiltration in tumor tissue were detected through immunofluorescence experiments. Results:125I-virus complex oncolytic adenovirus significantly increased tumor cell apoptosis in vitro and in vivo that was significantly higher than that of 125I group and virus complex group. Meanwhile, IL-2 ( t=-183.30, -38.20, P<0.05), IL-10 ( t=113.80, 92.71, P<0.05), TNF-α ( t=-73.20, -73.91, P<0.05), IFN-γ ( t=-65.37, -139.70, P<0.05) increased in vitro and in vivo. 125I-virus complex reduced the expression of CD24, CD44 and PSCA in tumor cells and tumor tissue, reduced the weight of tumor tissue, inhibited angiogenesis of tumor tissue ( t=8.55, P<0.05), and regulated the immune response in tumor tissue. Conclusions:125I-virus complex targeting prostate cancer can significantly kill cancer cells, reduce the weight and angiogenesis of tumor, and improve tumor microenvironment.

The short-term efficacy of the experimental group was better than that of the control group, and the difference was statistically significant ( Z=-2.623, P=0.009). The median PFS2 of the experimental group was 4.20 months (95% CI: 3.94-4.46), and the median PFS2 of the control group was 4.00 months (95% CI: 2.94-5.07), with a statistically significant difference ( χ2=4.948, P=0.026). Quality of life was compared between the two groups: in terms of physical function, emotional function and overall quality of life, score differences before and after treatment of the experimental group were higher than those of the control group, with statistically significant differences [6.67(-6.66, 20.00) vs. 0(-6.66, 6.66), Z=-2.429, P=0.015; 29.17(2.08, 56.26) vs. 12.49(-14.59, 39.57), Z=-2.263, P=0.024; 16.67(-33.33, 56.67) vs. 8.34(-18.74, 35.42), Z=-2.249, P=0.025]. In terms of immune function, CD4 + T cells level in the experimental group increased after treatment compared with that before treatment (44.27%±6.78% vs. 41.17%±3.73%, t=-2.426, P=0.022), and CD8 + T cells level decreased compared with that before treatment (21.47%±3.18% vs. 23.50%±2.37%, t=2.532, P=0.017). After treatment, the level of CD4 + T cells in the experimental group was significantly higher than that in the control group (44.27%±6.78% vs. 39.63%±5.80%, t=2.725, P=0.011). Conclusion:β-elemene combined with gefitinib has a certain effect in the treatment of advanced lung adenocarcinoma patients with slow progression after first-line gefitinib treatment, and the quality of life and immune function are improved. It is worthy of further clinical research.
