Hydroxysafflor Yellow A Promotes HaCaT Cell Proliferation and Migration by Regulating HBEGF/EGFR and PI3K/AKT Pathways and Circ_0084443 / 中国结合医学杂志

OBJECTIVE@#To investigate the effect and possible mechanism of hydroxysafflor yellow A (HSYA) on human immortalized keratinocyte cell proliferation and migration.@*METHODS@#HaCaT cells were treated with HSYA. Cell proliferation was detected by the cell counting kit-8 assay, and cell migration was measured using wound healing assay and Transwell migration assay. The mRNA and protein expression levels of heparin-binding epidermal growth factor (EGF)-like growth factor (HBEGF), EGF receptor (EGFR), phosphatidylinositol 3-kinase (PI3K), protein kinase B (AKT), mammalian target of rapamycin (mTOR), and hypoxia-inducible factor-1α (HIF-1α) were detected by quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot, respectively. Circ_0084443-overexpressing HaCaT cells and empty plasmid HaCaT cells were constructed using the lentiviral stable transfection and treated with HSYA. The expression of circ_0084443 was detected by qRT-PCR.@*RESULTS@#HSYA (800 µmol/L) significantly promoted HaCaT cell proliferation and migration (P<0.05 or P<0.01). It also increased the mRNA and protein expression levels of HBEGF, EGFR, PI3K, AKT, mTOR and HIF-1α, and increased the phosphorylation levels of PI3K and AKT (P<0.05 or P<0.01). Furthermore, HSYA promoted HaCaT cell proliferation and migration via the HBEGF/EGFR and PI3K/AKT/mTOR signaling pathways (P<0.01). Circ_0084443 attenuated the mRNA expression levels of HBEGF, EGFR, PI3K, AKT, mTOR and HIF-1α (P<0.05). HSYA inhibited the circ_0084443 expression, further antagonized the inhibition of circ_0084443 on HBEGF, EGFR, PI3K, AKT, mTOR and HIF-1α, and promoted the proliferation of circ_0084443-overexpressing HaCaT cells (P<0.05 or P<0.01). However, HSYA could not influence the inhibitory effect of circ_0084443 on HaCaT cell migration (P>0.05).@*CONCLUSION@#HSYA played an accelerative role in HaCaT cell proliferation and migration, which may be attributable to activating HBEGF/EGFR and PI3K/AKT signaling pathways, and had a particular inhibitory effect on the keratinocyte negative regulator circ_0084443.

Lycium barbarian seed oil activates Nrf2/ARE pathway to reduce oxidative damage in testis of subacute aging rats / 中国药理学通报

Aim To explore the effects of Lycium berry seed oil on Nrf2/ARE pathway and oxidative damage in testis of subacute aging rats. Methods Fifty out of 60 male SD rats, aged 8 weeks, were subcutaneously injected with 125 mg • kg"D-galactosidase in the neck for 8 weeks to establish a subacute senescent rat model. The presence of senescent cells was observed using P-galactosidase ((3-gal), while testicular morphology was examined using HE staining. Serum levels of testosterone (testosterone, T), follicle-stimulating hormone ( follicle stimulating hormone, FSH ) , luteinizing hormone ( luteinizing hormone, LH ) , superoxide dis-mutase ( superoxide dismutase, SOD ) , glutathione ( glutathione, GSH) and malondialdehyde ( malondial-dehyde, MDA) were measured through ELISA, and the expressions of factors related to aging, oxidative damage, and the Nrf2/ARE pathway were assessed via immunohistochemical analysis and Western blotting. Results After successfully identifying the model, the morphology of the testis was improved and the intervention of Lycium seed oil led to a down-regulation in the expression of [3-gal and -yH2AX. The serum levels of SOD, GSH, T, and FSH increased while MDA and LH decreased (P 0. 05) . Additionally, there was an up-regulated expression of Nrf2, GCLC, NQOl, and SOD2 proteins in testicular tissue ( P 0. 05 ) and nuclear expression of Nrf2 in sertoli cells. Conclusion Lycium barbarum seed oil may reduce oxidative damage in testes of subacute senescent rats by activating the Nrf2/ARE signaling pathway.

Expert Consensus on Clinical Diseases Responding Specifically to Traditional Chinese Medicine：Aural Vertigo / 中国实验方剂学杂志

Aural vertigo frequently encountered in the otolaryngology department of traditional Chinese medicine （TCM） mainly involves peripheral vestibular diseases of Western medicine， such as Meniere's disease， benign paroxysmal positional vertigo， vestibular neuritis， and vestibular migraine， being a hot research topic in both TCM and Western medicine. Western medical therapies alone have unsatisfactory effects on recurrent aural vertigo， aural vertigo affecting the quality of life， aural vertigo not relieved after surgery， aural vertigo with complex causes， and children's aural vertigo. The literature records and clinical practice have proven that TCM demonstrates unique advantages in the treatment of aural vertigo. The China Association of Chinese medicine sponsored the "17th youth salon on the diseases responding specifically to TCM： Aural vertigo" and invited vertigo experts of TCM and Western medicine to discuss the difficulties and advantages of TCM diagnosis and treatment of aural vertigo. The experts deeply discussed the achievements and contributions of TCM and Western medicine in the diagnosis and treatment of aural vertigo， the control and mitigation of the symptoms， and the solutions to disease recurrence. The discussion clarified the positioning and advantages of TCM treatment and provided guidance for clinical and basic research on aural vertigo.

Objective:To investigate epidemiological and clinical characteristics of botulism, and the adverse events among those received botulinum antitoxin treatment.Methods:Patients with discharge diagnosis as botulism in the Second Affiliated Hospital of Xinjiang Medical University were enrolled between 2017 and 2021. The epidemiological and clinical characteristics were evaluated. Infection and mechanical ventilation as in-hospital outcomes according to baseline characteristics were analyzed. Patients with and without the interested outcomes were compared. The adverse outcomes among those received botulinum antitoxin treatment were investigated. Those with and without the adverse outcomes were also compared.Results:Sixty-seven cases of botulism were enrolled, and most cases got sick between January and March (32/67, 47.8%); among them 62 cases were Han ethnicity (92.5%); prevalence was highest in Aksu region (15/67, 22.4%); commonly seen symptoms and signs included fatigue (58/67, 86.6%), dysphagia (48/67, 71.6%), dizziness (42/67, 62.7%), ptosis (42/67, 62.7%), blurred vision (41/67, 61.2%), and limb weakness (35/67, 52.2%). Compared with patients without in-hospital infection ( n=52), patients with in-hospital infection ( n=15) were more likely to have severe botulism (0/52 vs 5/15, χ 2=19.79, P<0.001), diplopia (16/52, 30.8% vs 11/15, χ 2=8.77, P=0.003), dysarthria (17/52, 32.7% vs 11/15, χ 2=7.91, P=0.005), consciousness disorder (1/52, 1.9% vs 4/15, χ 2=10.32, P=0.008). Compared with patients without mechanical ventilation (62/67, 92.5%), patients with mechanical ventilation (5/67, 7.5%) were more likely to have severe botulism (5/5 vs 0/62, χ 2=41.17, P<0.001), and consciousness disorder (4/5 vs 1/62, 1.6%, χ 2=29.58, P<0.001). Among 67 cases of botulism, 19 cases (28.4%) had adverse events after receiving antitoxin treatment, with an average of 6.5 days from the antitoxin treatment beginning to the adverse event onset; among the 19 cases, 18 cases (94.7%) had rash. Age, sex, and severity did not differ between the groups with ( n=19) and without adverse events ( n=48) after receiving antitoxin treatment. Conclusions:Fatigue, dysphagia, dizziness, ptosis were the most frequent symptoms and signs in the botulism in Xinjiang Uygur Autonomous Region, China. Infection was a commonly seen complication of botulism, and proactive prevention and close monitoring were needed. Adverse events after receiving antitoxin were prevalent, and might not be associated with age, sex, and severity of botulism.

Clinical features and genetic variants of children with hepatic Wilson′s disease / 中华全科医师杂志

Objective:To analyze the clinical characteristics and genetic variants of children with hepatic Wilson disease (WD).Methods:The clinical data and genetic test results of 35 children, who were diagnosed as WD with primary hepatic manifestation in the Department of Gastroenterology, Children′s Hospital of Capital Institute of Pediatrics from March 2018 to March 2022, were retrospectively analyzed. The relationship between phenotype and genotype of patients was analyzed.Results:Among 35 children, there were 24 males and 11 females with a median age at diagnosis of 5.5 (4.0, 7.5) years. All patients had elevated transaminases. The elevated transaminases was found during routine physical examination in 33 cases (94.3%), in whom there was no fever, cough, recurrent vomiting, abdominal pain, diarrhea, jaundice, limb tremor, gait instability and other discomfort 2 weeks before admission, except 1 case with nausea; abdominal ultrasonography showed that 5 cases (15.2%) had no abnormality, and others had different degrees of hepatomegaly, splenomegaly, and echo enhancement in liver parenchyma. Among the remaining 2 cases, one 11-year-old child presented with edema, and had cirrhosis portal hypertension with esophageal varices; another 7-year-old child was diagnosed as acute liver failure manifested with nausea and jaundice. Thirty three patients(94.3%)had decreased serum ceruloplasmin levels (<100 mg/L); 24-h urinary copper concentration was>100 μg in 16 cases (45.7%) and<40 μg in 2 cases (5.7%). The tests of hepatitis B virus, hepatitis C virus, cytomegalovirus and EB virus were all negative in 35 children, and the autoimmune hepatitis antibodies were also negative. A total of 34 different ATP7B gene mutations were detected; the most frequent mutation was c.2333G>T (P.R778L) at exon 8, followed by c.2621C>T(p.A874V)at exon 11 and c.2621C>T(p.A874V)at exon 13. There was no significant difference in clinical phenotype between patients with nonsense mutation, frameshift mutation or splicing mutation and those with only missense mutations( Z=-1.00, t=-0.16, Z=-1.14, Z=-1.03,all P>0.05). Conclusions:The onset of WD in children is obscure, and clinicians should consider this disease in patients presenting with elevated transaminase. Ceruloplasmin and urine copper should be tested timely, the early diagnosis and treatment can improve the prognosis. And there is no significant correlation between genotype and clinical phenotype.

Intervention effect of network mental health education based rehabilitation platform on patients with bipolar disorder in remission stage / 中华健康管理学杂志

Objective:To analyze the intervention effect of rehabilitation platform-based online psycho-education on patients with bipolar disorder (BD) in remission stage.Methods:In this randomized controlled study, 91 patients with BD in remission stage who attended the community health center in Xicheng District, Beijing from July to August 2021 were randomly divided into a test group (46 cases) and a control group (45 cases) according to a 1∶1 ratio using the random number table. Baseline data were collected from both groups, and the control group received conventional medication and community telephone follow-up, while the test group was given online mental health education in the form of a WeChat subscription number on this basis, including BD mental health education course push (twice a week) and disease self-management (daily recording of mood, sleep, medication, exercise and gratitude diary), and the intervention period was 6 months in both groups. During the intervention, one patient in the test group was admitted to hospital due to exacerbation of mental illness and the trial was terminated. A total of 90 cases were included in the study. The scores of Medication Adherence Rating Scale (MARS), Hamilton Depression Scale (HAMD), Young Mania Rating Scale (YMRS) and Perceived Devaluation-Discrimination Scale (PDD) were assessed at baseline, after 3 months and 6 months of intervention in both groups, respectively. And the differences in baseline data between the two groups were compared using two independent samples t test and χ2 test, and the repeated-measures ANOVA was used to compare the differences in MARS, HAMD, YMRS, and PDD scores between the two groups before and after the intervention, and to analyze the intervention effects of network mental health education based on the rehabilitation platform on patients in remission stage of BD. Results:After 6 months of intervention, MARS scores in the test group was significantly higher than that in the control group [(8.47±1.75) vs (7.47±1.85)], and was significantly higher than that at baseline (7.36±2.13) and after 3 months of intervention (8.04±1.68) (all P<0.05). YMRS and PDD scores in the test group were significantly lower than those at baseline after 3 and 6 months of intervention [YMRS, 2.0(1.0,4.0),2.0(0,3.0) vs 3.0(1.0,5.5); PDD, (31.18±4.65), (30.13±4.76) vs (32.51±4.51)] (all P<0.05); the differences in YMRS and PDD scores in the control group were not statistically significant (all P>0.05). There was no statistically significant difference in HAMD scores between the two groups before and after the intervention (all P>0.05). Conclusion:Combining mental health education based on rehabilitation platform with conventional medication and community management can significantly improve the medication compliance of patients with BD in remission stage, and improve their manic symptoms and reduce the stigma of the disease.

Value of quantitative parameters of enhanced MRI in predicting collateral circulation in patients with renal cell carcinoma and inferior vena cava tumor thrombus / 中华放射学杂志

Objective:To explore the value of quantitative parameters of enhanced MRI in predicting the establishment of inferior vena cava collateral circulation in patients with renal cell carcinoma and inferior vena cava tumor thrombus.Methods:Sixty-seven patients with renal cell carcinoma and inferior vena cava tumor thrombus who underwent radical resection and inferior vena cava venography in First Medical Center, PLA General Hospital from May 2006 to January 2021 were included retrospectively. According to the results of inferior vena cava venography, the patients were divided into two groups: the well-established collateral circulation group ( n=41) and the poor-established collateral circulation group ( n=26). Quantitative parameters were measured on preoperative enhanced MRI images, including tumor size, the maximum diameter of bilateral lumbar veins, the length of tumor thrombus, and the long and short diameters of tumor thrombus. Student′s t test or Mann-Whitney U test was used for comparison between the two groups. The independent risk factors related to the establishment of collateral circulation were obtained by binary logistic regression analysis and the model was established. The receiver operating characteristic curve was employed to evaluate MRI quantitative parameters and the logistic model, and the area under the curve (AUC) was compared by the DeLong test. Results:Between the well-established collateral circulation group and the poor-established collateral circulation group, the maximum diameter of the right lumbar vein, the maximum diameter of the left lumbar vein, the length of the tumor thrombus, the long diameter of the tumor thrombus, and the short diameter of the tumor thrombus were different significantly ( P<0.05). There was no significant difference in the tumor size between the two groups ( t=0.30, P=0.766). The AUC of the maximum diameters of the right lumbar veins and left lumbar veins, length of tumor thrombus, long and short diameters of tumor thrombus in predicting the collateral circulation were 0.917 (95%CI 0.824-0.971), 0.869 (95%CI 0.764-0.939), 0.756 (95%CI 0.636-0.853), 0.886 (95%CI 0.785-0.951), and 0.906 (95%CI 0.809-0.963). The AUC of the maximum diameter of the right lumbar vein and the short diameter of the tumor thrombus were larger than those of the length of the tumor thrombus, and the differences were statistically significant ( Z=2.25, 2.04, P=0.025, 0.041), but the AUC between other parameters had no significant difference ( P>0.05). The maximum diameter of the right lumbar vein (OR 24.210, 95%CI 2.845-205.998), the maximum diameter of the left lumbar vein (OR 20.973, 95%CI 2.359-186.490), and the length of the tumor thrombus (OR 23.006, 95%CI 2.952-179.309) were independent risk factors for predicting the establishment of inferior vena cava collateral circulation. The AUC of logistic model was 0.969 (95%CI 0.931-1.000). Conclusion:Quantitative parameters of tumor thrombus and lumbar vein based on enhanced MRI have a good ability in predicting the establishment of inferior vena cava collateral circulation in patients with renal cell carcinoma and inferior vena cava tumor thrombus. The maximum diameter of bilateral lumbar veins and the length of the tumor thrombus were independent risk factors for inferior vena cava collateral circulation.

Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly (version 2023) / 中华创伤杂志

Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.

Objective To compare the consistency of quantitative ultrasound(QUS)and dual-energy X-ray absorptiometry(DXA)in measuring bone mineral density(BMD)of adults aged 18-40 years in Guangzhou and evaluate the diagnostic value of QUS for identifying low bone mass.Methods DXA was employed to measure the BMD and QUS to measure the speed of sound(SOS)in 731 participants.The Bland-Altman analysis was performed to evaluate the consistency of Z scores between SOS and BMD.With the BMD Z ≤-2.00 as the diagnostic criterion for low bone mass,the receiver operating characteristics curve of QUS was established,and the area under the curve(AUC)and the sensitivity,specificity,and correct diagnostic index for the optimal cut-off of SOS Z score were calculated.Results The results of Bland-Altman analysis showed that the mean differences in the Z scores of SOS and BMD in males and females were 1.27(-0.94 to 3.47)and 0.93(-1.33 to 3.18),respectively.The AUC of SOS Z score in the diagnosis of low bone mass in males and females was 0.734(95%CI=0.380-0.788)and 0.679(95%CI=0.625-0.732),respectively.In males,the optimal cut-off of SOS Z score for low bone mass was -0.35,with the sensitivity,specificity,and correct diagnostic index of 64.1%,68.6%,and 0.327,respectively.In females,the optimal cut-off value of SOS Z scores for low bone mass was -1.14,with the sensitivity,specificity,and correct index of 73.9%,54.8%,and 0.285,respectively.Conclusion QUS and DXA show poor consistency in the diagnosis of BMD in the adults aged 18-40 years in Guangzhou,while QUS demonstrates an acceptable value in identifying low bone mass.

Association Between Dietary Knowledge and Food Preferences in Residents Aged 18 and Over in China Based on Latent Class Analysis / 中国医学科学院学报

Objective To investigate the food preferences and explore the potential association between dietary knowledge and food preferences in residents aged 18 and over in China,so as to provide a basis for promoting healthy diets.Methods The latent class analysis was carried out with the 2015 cross-sectional data of China health and nutrition survey to categorize the food preferences among 8 783 residents aged 18 and over.Multinomial Logistic regression was adopted to assess the association between and dietary knowledge and food preferences.Results The food preferences of the residents aged 18 and over in China were classified into preference for less vegetable(3.28%),lack of preference(11.20%),diverse preferences(4.19%),and preference for healthy diets(81.33%).The proportion of the adults with dietary knowledge was 36.87%(3 238/8 783).The dietary knowledge varied in the adults with different food preferences(all P<0.001).After adjusting for gender,age,urban and rural distribution,education background,and annual household income,for each point increase in the dietary knowledge score,there was an estimated reduction of 22% in the probability of preferring less vegetables(OR=0.78,95%CI=0.76-0.80, P<0.001),13% in the probability of lacking preference(OR=0.87,95%CI=0.86-0.89, P<0.001),and 3% in the probability of having diverse preferences(OR=0.97,95%CI=0.94-1.00, P=0.030).Compared with those lacking dietary knowledge,the individuals with dietary knowledge had a 77% less probability of preferring less vegetables(OR=0.23,95%CI=0.16-0.32, P<0.001),a 55% less probability of lacking preference(OR=0.45,95%CI=0.39-0.53, P<0.001),and a 23% less probability of having diverse preferences(OR=0.77,95%CI=0.61-0.96, P=0.023).Conclusions The residents aged 18 and over in China presented four food preferences,including preference for less vegetables,lack of preference,diverse preferences,and preference for healthy diets,the last of which had the highest proportion.The individuals with lower levels of dietary knowledge have higher probability of preferring unhealthy food.

Effects of volatile oil from Acori graminei Rhizoma on glial fibrillary acidic protein, c-Jun N-terminal protein kinase and tumor necrosis factor-α expressions in the spinal cord dorsal horn of the inflammatory pain rats / 解剖学报

Objective To investigate the influence of volatile oil from Acori graminei Rhizoma (VOA) on expressions of glial fibrillary acidic protein (GFAP), c-Jun N-terminal protein kainse (JNK) and tumour necrosis factor-α (TNF-α) in the spinal cord dorsal horn of imflammatory pain rats. Methods Totally 36 male SD rats were randomly divided into control group (control), sham-operated group (sham), complete Freund' s adjuvant group (CFA), 5 g/(kg·d) low dose VOA+CFA group (VOA-L+CFA), 10 g/(kg·d) medium dose VOA + CFA group (VOA-M+CFA) and 20 g/(kg·d) high dose VOA + CFA group (VOA-H+CFA). All animals were sacrificed immediately after continuous gavage administration for 22 days. The expressions of GFAP, JNK and TNF-α in the spinal cord dorsal horn of rats in each group were detected by immunofluorescence and Western blotting methods. Results The present results showed that the positive expressions of GFAP, JNK and TNF-α in the spinal cord dorsal horn of rats increased significantly in the CFA group, when compared to the control and sham groups (P < 0. 01). The expressions of GFAP, JNK and TNF-α in the spinal cord dorsal horn of rats with VOA treatment reduced in the dose-dependent manner, when compared to the CFA group, the positive expressions of GFAP, JNK and TNF-α reduced significantly in the dorsal horn of the spinal cord of the VOA-H+CFA group (P<0. 05, P<0. 01). Conclusion VOA reduces the expressions of GFAP, JNK and TNF-α in the spinal cord dorsal horn of rats of CFA-induced inflammatory pain.

Glomuvenous malformation: a clinicopathological analysis of 31 cases / 中华病理学杂志

Objective: To investigate the clinicopathological features of glomuvenous malformation (GVM). Methods: Thirty-one cases of GVM diagnosed at the Henan Provincial People's Hospital from January 2011 to December 2021 were collected. Their clinical and pathological features were analyzed. The expression of relevant markers was examined using immunohistochemistry. The patients were also followed up. Results: There were 16 males and 15 females in this study, with an average age of 11 years (range, 1-52 years). The locations of the disease included 13 cases in the limbs (8 cases in the upper limbs, 5 cases in the lower limbs), 9 cases in the trunks, and 9 cases in the foot (toes or subungual area). Twenty-seven of the cases were solitary and 4 were multifocal. The lesions were characterized by blue-purple papules or plaques on the skin surface, which grew slowly. The lumps became larger and appeared to be conspicuous. Microscopically, GVM mainly involved the dermis and subcutaneous tissue, with an overall ill-defined border. There were scattered or clustered irregular dilated vein-like lumens, with thin walls and various sizes. A single or multiple layers of relatively uniform cubic/glomus cells were present at the abnormal wall, with scattered small nests of the glomus cells. The endothelial cells in the wall of abnormal lumen were flat or absent. Immunohistochemistry showed that glomus cells strongly expressed SMA, h-caldesmon, and collagen IV. Malformed vascular endothelial cells expressed CD31, CD34 and ERG. No postoperative recurrence was found in the 12 cases. Conclusions: GVM is an uncommon type of simple venous malformation in the superficial soft tissue and different from the classical glomus tumor.

Spatial expression of the nonsense-mediated mRNA decay factors UPF3A and UPF3B among mouse tissues / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

无义介导的信使RNA（mRNA）降解途径（nonsense-mediated mRNA decay，简称为NMD)是真核生物细胞内一种重要的基因转录后表达调控机制，它积极参与一系列细胞生理和生化过程，控制细胞命运和生命体的组织稳态。NMD的缺陷会导致人类疾病，如神经发育障碍、肿瘤发生和自身免疫疾病等。UPF3 (Up-frameshift protein 3)是一个核心的NMD因子，它最早在酵母中被发现。UPF3A和UPF3B是UPF3在生物进化到脊椎动物阶段出现的两个旁系同源物，在NMD中具有激活或抑制的作用。以往研究发现，UPF3B蛋白几乎在所有哺乳动物器官中均有表达，而UPF3A蛋白在除睾丸外的大多数哺乳动物组织中难以被检测到。解释这一现象的假说为：在NMD途径中，UPF3B具有比UPF3A更高的竞争性结合UPF2的能力，UPF3B和UPF2的结合促使UPF3A成为游离状态，而游离的UPF3A蛋白不稳定且易被降解。此假说提示UPF3A和UPF3B在NMD中存在拮抗作用。在本研究中，我们重新定量评估了UPF3A和UPF3B在野生型成年雄性和雌性小鼠的9个主要组织和生殖器官中的mRNA和蛋白表达，结果证实UPF3A在雄性生殖细胞中表达量最高。令人惊讶的是，我们发现在包括大脑和胸腺在内的大多数组织中，UPF3A与UPF3B的蛋白水平相当，而在小鼠脾、肺组织中，UPF3A表达高于UPF3B。公共基因表达数据进一步支持了上述发现。因此，我们的研究表明了UPF3A是小鼠组织中普遍表达的NMD因子。同时，该研究结果推测：在生理条件下，UPF3A和UPF3B蛋白之间不存在竞争抑制，且UPF3A在多种哺乳动物组织的稳态中发挥重要作用。

Discovery of biomarkers related to abnormal lipid metabolism in liver and serum and intervention mechanism of ginsenoside Rb_1 in hyperlipidemia rats based on non-targeted metabolomics / 中国中药杂志

Through the non-targeted metabolomics study of endogenous substances in the liver and serum of hyperlipidemia rats, the biomarkers related to abnormal lipid metabolism in hyperlipidemia rats were found, and the target of ginsenoside Rb_1 in improving hyperlipidemia was explored and its mechanism was elucidated. The content of serum biochemical indexes of rats in each group was detected by the automatic biochemical analyzer. The metabolite profiles of liver tissues and serum of rats were analyzed by HPLC-MS. Principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) were used to compare and analyze the metabolic data in the normal group, the hyperlipidemia group, and the ginsenoside Rb_1 group, and screen potential biomar-kers. The related metabolic pathways were further constructed by KEGG database analysis. The results showed that hyperlipemia induced dyslipidemia in rats, which was alleviated by ginsenoside Rb_1. The non-targeted metabolomics results showed that there were 297 differential metabolites in the liver tissues of hyperlipidemia rats, 294 differential metabolites in the serum samples, and 560 diffe-rential metabolites in the hyperlipidemia rats treated by ginsenoside Rb_1. Perillic acid and N-ornithyl-L-taurine were common metabolites in the liver and serum samples, which could be used as potential biomarkers for ginsenoside Rb_1 in the improvement of hyperlipidemia. As revealed by pathway enrichment in the liver and serum, ginsenoside Rb_1 could participate in the metabolic pathway of choline in both the liver and serum. In addition, ginsenoside Rb_1 also participated in the ABC transporter, alanine, aspartic acid, and glutamate metabolism, protein digestion and absorption, β-alanine metabolism, taurine and hypotaurine metabolism, caffeine metabolism, valine, leucine, and isoleucine biosynthesis, arachidonic acid metabolism, and methionine and cysteine metabolism to improve dyslipidemia in rats.
