Circular RNA (circRNA) is a special class of non-coding RNA (ncRNA) in eukaryotic cells, which is highly stable. At present, circRNA has been widely found to be involved in the occurrence and development of various diseases as microRNA (miRNA) sponges. As a research hotspot in recent years, the function and effects of circRNA are constantly being discovered and utilized. CircRNAs can act as protein scaffolds to bind targets more tightly and regulate transcription of disease signaling molecules, as well as participate in protein expression as translation templates. A substantial body of research has established the pivotal role of ferroptosis in disease development. Iron and lipid metabolism-related targets are recognized as key components in the regulation of ferroptosis. Recent studies have revealed that circRNA not only participates in ferroptosis regulation as a miRNA and protein scaffold but also exerts control over ferroptosis-related signaling molecules at the transcriptional level. Currently, synthetic circRNA molecules have been engineered for the development of RNA vaccines. Additionally, a range of gene therapy technologies and drug delivery vectors offer a promising foundation for the development of therapeutics targeting circRNA. This paper describes the functions and effects of circRNA, its role as a key target in the regulation of ferroptosis, and its implications in various diseases. Special emphasis is placed on discussing the role of circRNA in multisystem diseases, including tumors, nervous system disorders, and diabetes-related complications. Additionally, drug development strategies related to circRNA are summarized to provide insights for the development of therapeutic drugs targeting ferroptosis. [ABSTRACT FROM AUTHOR]

Objective: To investigate the clinical significance and its predictive value of serum leukocyte cell-derived chemotaxin-2 (LECT2) levels in patients with postmenopausal osteoporosis. Methods: 125 patients with postmenopausal osteoporosis who were admitted to The First Affiliated Hospital of Hunan Normal University from January 2020 to January 2022 were selected as the study group, and 120 postmenopausal healthy female volunteers who underwent physical examination during the same period were selected as the control group. Serum LECT2 levels were compared in the two groups, and the correlation between serum LECT2 levels and bone mineral density (BMD) and bone metabolism indexes of lumbar spine and femoral neck was analyzed. The predictive value of serum LECT2 for postmenopausal osteoporosis patients was analyzed by receiver operating characteristic(ROC)curve. Results: Serum LECT2, osteocalcin (OC), type I procollagen n-terminal peptide (PINP) and type I collagen cross-linked C-terminal peptide (S-CTX) in the study group were significantly higher than those in the control group, while BMD of lumbar spine and femoral neck were significantly lower than those in the control group(P<0.05). Pearson correlation analysis showed that the serum LECT2 level in the patients with postmenopausal osteoporosis was positively correlated with the OC, PINP and S-CTX levels(P<0.05), and negatively correlated with the BMD of lumbar spine and femoral neck(P<0.05). ROC curve analysis showed that the AUC of the combined test of serum LECT2, OC, PINP, and S-CTX for predicting postmenopausal osteoporosis patients was 0.856, which was greater than the predicted value of each single indicator. Conclusion: The serum LECT2 level is increased in postmenopausal women with osteoporosis, which is positively correlated with the bone metabolic indexes OC, PINP and S-CTX, and which is negatively correlated with lumbar spine BMD and femoral neck BMD. Serum LECT2 level combined with OC, PINP, S-CTX has higher predictive value for postmenopausal osteoporosis patients. [ABSTRACT FROM AUTHOR]

Objective To analyze the relationships of T-box transcription factor 19 (TBX19) expression levels in pan-cancer tissues with patients' prognosis and the tumor immune microenvironment (immune cell infiltration, immune checkpoint genes, tumor mutation burden, and microsatellite instability) based on database data. Methods TBX19 expression levels in the pan-cancer tissues and corresponding normal tissues were obtained from The Cancer Genome Atlas (TCGA) database, and the TBX19 expression levels were compared in the pan-cancer tissues of patients with different WHO grades and TNM stages. Using Cox regression to analyze the relationship between TBX19 expression levels and the prognosis of tumor patients. The correlation between TBX19 expression levels and the abundance of immune cell infiltration was analyzed by Pearson method based on data from the Tumor Immune Estimation Resource (TIMER2). Correlations of TBX19 expression levels with immune scores, tumor mutation burden and microsatellite instability were analyzed by Pearson method using TCGA database in the Sanger Box website. Based on the Clinical Biosense House database data, the correlations between TBX19 expression levels and immune checkpoint genes were analyzed by the Spearman method. Re⁃ sults TBX19 was highly expressed in bladder urothelial carcinoma, cholangiocarcinoma, colon adenocarcinoma (CO‑AD), colorectal carcinoma (COADREAD), esophageal carcinoma, head and neck squamous cell carcinoma, renal clear cell carcinoma, renal papillary cell carcinoma, pan-kidney cohort, hepatocellular carcinoma (LIHC), lung adenocarcinoma, lung squamous cell carcinoma, pheochromocytoma and paraganglioma, rectum adenocarcinoma, gastric carcinoma, and stomach and esophageal carcinoma tissues (all P<0. 05), and was low expressed in breast invasive carcinoma, kidney chromophobe cell tumor, prostate adenocarcinoma, and endometrial carcinoma tissues (all P<0. 05). There were statistically significant differences in the TBX19 expression in COAD and COADREAD cancer tissues with different WHO grades as well as different TNM stages (all P<0. 05). Compared the tissues with low TBX19 expression, those with high TBX19 expression in LIHC cancer tissues had shorter overall survival, disease-specific survival, disease-free interval, and progression-free interval (all P<0. 05). In the COAD, KIRC, LIHC and other cancer tissues, TBX19 expression was closely associated with immune cell infiltration, immune checkpoint genes, tumor mutation burden, and microsatellite instability (all P<0. 05). Conclusions TBX19 expression levels in the pan-cancer tissues are predominantly elevated, and those with high TBX19 expression have poorer prognosis. High TBX19 expression in cancer tissues is associated with the tumor immune microenvironment, including elevated levels of immune infiltration, increased tumor mutation burden, and increased microsatellite instability in diverse tumors.

In the cultivation of medicinal plants, the problem of soil heavy metal pollution is quite prevalent, and cadmium is one of the most pervasive and poisonous heavy metals in the soil, making it particularly dangerous. Pogostemon cablin is the main component of a variety of traditional Chinese patent medicines and simple preparations. Pogostemon cablin was used as the experimental material, a pot controlled experiment method was used to study the effects of different concentrations of cadmium stress on the agronomic traits, antioxidant enzyme activity, malondialdehyde, soluble protein, chlorophyll content, and effective component content. The results show that the growth of plant height and fresh weight of Pogostemon cablin was inhibited under cadmium stress. High concentration stress can inhibit antioxidant enzyme activity, but lower concentration stress can actually activate the antioxidant response of patchouli. The soluble protein content in patchouli shows a decreasing trend under cadmium stress. The content of malondialdehyde shows an overall upward trend with the prolongation of stress time. With the extension of cadmium stress time, the hydrogen peroxide content in the high concentration treatment group reaches its peak on the 30th day, with the largest increase. Meanwhile, cadmium has a significant (P < 0. 05) reducing effect on the chlorophyll content of patchouli. In addition, the secondary metabolites of patchouli are also affected by cadmium. The overall content of Baiqiu plum alcohol in the experimental group shows an upward trend, but the increment is significantly reduced compared to the control group. The content of Pogostemon cablin ketone shows a decreasing trend, and after 30 days of treatment, the content of Pogostemon cablin ketone in the experimental group decreased by 40. 46% . It can be seen that cadmium stress can affect the physiological state of Pogostemon cablin, and under low concentration and short-term cadmium stress, the physiological state of Pogostemon cablin is activated, while under high concentration and long-term cadmium stress, the physiological state of Pogostemon cablin is inhibited. The research results will play a positive guiding role in reducing soil heavy metal pollution. [ABSTRACT FROM AUTHOR]

With the change of work styles more and more people sit in front of computer desks for a long time. People who keep a sitting posture for more than six hours a day are classified as the sedentary people. For most sedentary people it is unconscious to sit with a poor sitting posture and hard to correct. Poor sitting posture may lead to harm to the cervical thoracic and lumbar spines even to the breathing and digestion system. Therefore sedentary people should correct their poor sitting posture to keep the spine in a natural bending state which can avoid the injury of the spine. Wearable sitting posture correction products can effectively correct the sitting posture and relieve the fatigue of the waist and back. Currently the main wearable sitting correction products in the market are posture correction belts. However wearing a traditional posture correction belt with strong sense of bondage for a long period would possibly cause excessive posterior extension of the shoulder joint and lumbar spine. In addition the development of science and technology promotes the innovation of smart sitting posture correction garments. The core of such products is a smart posture correction system while the style structure and correction function of the sitting posture correction garment itself are neglected. Based on ergonomics and garment material science we developed a sitting posture adjustment vest that can correct the sitting posture of the sedentary people. Different from traditional posture correction belts the sitting posture adjustment vest consists of an external vest and an internal correction belt in structure. The internal correction belt is divided into the body restraint and shoulder elastic area based on specific functions. In the body restraint area there are lots of small holes on the scapula to increase the breathability. And the bionic cartilage strip on the back waist can support the waist and relieve fatigue. In the shoulder elastic area two elastic straps are set separately on the two sides of the shoulder and avoid the underarm part which decreases the binding sensation of the armpit. Additionally different functional areas are matched with different clothing fabrics to improve the wearable comfort. All of the fabrics selected have great moisture-absorbing and breathable performance. Through the use of Velcro buckles and snaps the sitting posture adjustment vest has a good adjustable function and is easy to put on and take off. In this study five female subjects were invited to participate in the experiment of human wearing to test and evaluate the thermal and humidity comfort and the sitting posture reclamation function of the sitting posture adjustment vest. Measurements include physiological indicators and a subjective questionnaire. During the experiment of thermal and humidity comfort evaluation subjects were required to keep sitting for 30 min and fill out the subjective evaluation questionnaire every 10 min. The temperature and humidity of the four marked points of the vest were recorded with an interval of 1 min. As for the evaluation of sitting posture adjustment function we observed and measured the change in the curve of the human back and the angle of the body surface. And the subjects needed to fill out the subjective evaluation questionnaire for sitting adjustment performance. The measurement results show that the vest has favorable thermal and humidity comfort. For subjects sitting still at a temperature of 23 ℃ and a relative humidity of 60% the local surface temperature under the clothing increases at first and stabilizes below 32. 5 ℃ after 5 min while the humidity decreases with a change range of 6. 6% - 9. 5% . The mean temperature of the back is 1. 12 ℃ higher than that of the waist because of the better fit between clothing and body. And subjects are not sweating. After wearing the sitting posture adjustment vest the poor spine shape of subjects is significantly improved and the spine curve is closer to the normal curvature of the human spine. Furthermore the upper back angle of the subjects wearing the vest significantly decreases while the lower back angle increases. It indicates that the vest has good sitting posture correction performance. According to the results of subjective evaluation the subjects are basically satisfied with the comfort and correction function of the sitting posture adjustment vest. The sitting posture adjustment vest can meet the needs of wearing for a long time for the sedentary people. In recent years there has been increasing attention on the research of smart wearable posture correction products. The sitting posture adjustment vest can provide reference for the design of smart sitting posture correction clothing. Combined with the smart posture correction system that is based on the machine learning algorithm a smart sitting posture correction garment with both passive correction and warning correction can be developed.

Background Insomnia disorder has become a common disease in the current society. Cognitive Behavior Therapy for Insomnia(CBTI)is one of the non-drug treatment methods for insomnia disorder, but relevant studies of its effect on sleep quality and cognitive function of patients with insomnia disorder are limited. Objective To explore the effects of CBTI on sleep quality and cognitive function in patients with insomnia disorder, so as to provide references for non-drug treatment of insomnia disorder. Methods A total of 47 patients with insomnia disorder were recruited as the study subjects. They all met the diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorders, fifth edition(DSM-5)and have visited Sichuan Mental Health Center from January 2021 to October 2022. The patients underwent CBTI for 6 weeks. Before the treatment, depression and anxiety symptoms were assessed using Hamilton Depression Scale-24 item(HAMD-24)and Hamilton Anxiety Scale(HAMA）. Sleep status and cognitive function were assessed using Pittsburgh Sleep Quality Index(PSQI)and Montreal Cognitive Assessment(MoCA)before and 6 weeks after the treatment. Spearman correlation analysis was used to examine the correlation between the reduction of PSQI score and the increase of MoCA score after treatment. Results After the 6-week treatment, the factor scores and total score of PSQIacross 6 subscales(the sleep quality, sleep onset time, sleep time, sleep efficiency, sleep disorder and daytime dysfunction)were lower than those before the treatment, and the score differences were of statistical significance(t=5. 569~15. 290，P<0. 01）. Both factor and total scores of MoCA across 6 items(visuospatial and executive, naming, attention, language, abstraction and memory)were significantly higher than those before the treatment with score differences reaching statistical significance(t=-11. 273~ -4. 277，P<0. 01）. Spearman correlation analysis demonstrated that there was a positive correlation between the decrease in PSQI total score and the increase in MoCA total score after the 6-week CBTI treatment(r=0. 323，P=0. 027）. Conclusion CBTI may help improve sleep quality and cognitive function in patients with insomnia disorders. The improvement of sleep quality after CBTI intervention may be related to the improvement of cognitive function. ［Funded by Scientific Research Project of Sichuan Provincial Health Commission(number，19PJ216）］ [ABSTRACT FROM AUTHOR]
