ABSTRACT
As cell aggregates in three-dimensional culture derived from primary tissues or stem cells, organoids possess the ability to self-organize into organotypic structures, mimic the cellular microenvironment, and represent tissue physiology. The thyroid′s follicular tissue plays a crucial role in thyroid hormone biosynthesis. Despite prolonged in vitro expansion of thyroid follicles from adult tissues and pluripotent stem cells have been expanded for a long time, the development of thyroid organoid technology still encounters numerous challenges. Establishing a comprehensive thyroid organoid that closely mimics the human body′s actual conditions remains a research challenge. This article reviews the development process of thyroid, the related applications of existing thyroid organoid models and the methods employed in the construction.
ABSTRACT
Objective:To systematically evaluate the efficacy and safety of iGlarLixi in the treatment of type 2 diabetes, providing evidence-based support for rational clinical medication.Methods:A systematic review was conducted by retrieving articles from PubMed, Embase, Cochrane Library, Web of Science, Sinomed, CNKI, Wanfang, and VIP databases to collect randomized controlled trials comparing the efficacy and safety of iGlarLixi(intervention group) with placebo or other anti-hyperglycemic drugs(control group) in the treatment of type 2 diabetes. The search was conducted from the inception of the databases up to August 2022. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias in the included studies. Meta-analysis was performed using RevMan 5.4 software. Results:A total of 11 studies with 6 392 patients were included in the meta-analysis. The results of the meta-analysis showed that in terms of efficacy, compared to insulin and GLP-1RAs, iGlarLixi demonstrated better reduction in patients′ HbA 1C levels(Insulin group WMD=-0.40, 95% CI -0.54--0.27, P<0.001; GLP-1RAs group WMD=-0.86, 95% CI -1.05--0.68, P<0.001), increased HbA 1C target rate(Insulin group OR=2.83, 95% CI 2.00-3.99, P<0.001; GLP-1RAs group OR=6.45, 95% CI 4.81-8.64, P<0.001), increased HbA 1C control rate without weight gain(Insulin group OR=3.00, 95% CI 2.43-3.71, P<0.001; GLP-1RAs group OR=2.67, 95% CI 1.76-4.06, P<0.001). Furthermore, iGlarLixi showed an advantage in weight reduction compared to the insulin group and demonstrated superior reduction in fasting plasma glucose compared to the GLP-1RAs group. In terms of safety, the incidence of hypoglycemic events in the iGlarLixi group was similar to that in the insulin group, but the incidence of gastrointestinal adverse events was higher than that in the insulin group. There was no difference in the incidence of gastrointestinal adverse events compared with GLP-1RAs, but the incidence of hypoglycemic events was higher in the iGlarLixi group. The incidence of serious adverse events was similar to that in the insulin and GLP-1RAs groups(Insulin group OR=0.94, 95% CI 0.71-1.23, P=0.640; GLP-1RAs group OR=0.97, 95% CI 0.61-1.52, P=0.880). Conclusion:iGlarLixi is superior to insulin but inferior to GLP-1RAs in reducing body weight, and the overall incidence of adverse events is not significantly different from that of insulin and GLP-1RAs, indicating that iGlarLixi is well tolerated and safe, and has a good clinical application prospect.
ABSTRACT
Gut microbiota are closely related to human health. Studies have shown that probiotics, prebiotics and synbiotics play an important role in maintaining intestinal microbiota balance and improving blood glucose, but their use is limited in certain special periods, such as pregnancy, immunodeficiency, and severe infection. Postbiotics is defined as inactivated bacteria and bacterial components that are beneficial for the host, including cell structure, secretory molecules or metabolites and inanimate microorganisms. The heterogeneous molecular metabolite shows a wide range of action mechanisms and plays an important role in restoring intestinal flora and improving blood glucose. This paper reviews the mechanism and research progress of postbiotics regulation of blood glucose.
ABSTRACT
Objective To discusses the efficacy and safety of patent ductus arteriosus sealing for low body weight children. Methods From January 2008 to June 2012 in our hospital,32 cases (male14 and female 18) of PDA babies< 8 kg weight were given transcatheter closure treatment. The enrolled PDA babies aged 6 month-18 months, average (11 ±5.5 months),weighted (7.2 ±0.6) kg,aortic imaging showed the narrowest diameter of PDA was 1 ~ 8 mm (4.6 ±1.7) mm,descending aorta imaging was performed immediately and 30 min after transcatheter closure treatment. Echocardiography and X-ray radiography examination were performed 1 d,1,3, 6 months after treatment. Results 30 cases got successful patent ductus arteriosus sealing,all the successful patients were treated with domestic closer,and 1 case was complicated with the descending aorta stenosis and ventricular septal defect, and was transferred to surgerical treatment. 1 case of PDA gave up patent ductus arteriosus sealing as descending aorta stenosis caused by the closer. 2 cases were found a trace-residual shunt immediately after patent ductus arteriosus sealing. No serious complications were found in all patients during the follow-up period. Conclusions Application of domestic closer in treatment of PDA infants < 8 kg is a safe, effective and simple intervention treatment method with little trauma and fast recovery.
ABSTRACT
Objective To study the effect of implanted stent or selected operation in patients with acute occlusion of right coronary artery during the emergency coronary arteriongraphy. Methods Forty-three patients with acute occlusion of right coronary artery who underwent the emergency coronary arteriongraphy were divided into two groups: the implanted stent group ( n = 23) during the emergency coronary arteriongraphy and the selected operation group (n =20) during the emergency coronary arteriongraphy . Then we observed the general data, the coronary artery pathological changes, preoperative and postoperative thrombus, the blood flow, remained stenosis and the prognosis. Results The implanted stent group was similar to the control group in general condition, but implanted stent group was significantly different from the control group in the near, intermediate and distal coronary artery pathological changes ( <0.05) . The control group was significantly different from the implanted stent group in the thrombus and slowly blood flow ( <0.05) . After three months, we reviewed coronary arteriongraphy and selected operation, The implanted stent group was significantly different from the control in the remained stenosis and slowly blood flow (<0.05) . But the implanted stent group was similar to the control groug in the thrombus and new proceeding cardiovascular events. Conclusion When thrombus appears in acute occlusion of right coronary artery, we can implant stent during the emergency coronary arteriongraphy if the thrombus is little, or we can select operation after PTCA on the contrary.

ABSTRACT
The renal protective effect of complement factor H(CFH)and adrenomedullin (AM) on rat mesengial ceils (HBZY-1) cultured under high glucose levels was investigated. Results indicated that AM and CFH inhibited the expressions of transforming growth factor-β1 and extracellular matrix in HBZY-1 cells, suggesting that CFH and AM in combination seem to show some renal protective effects on diabetic nephropathy.
ABSTRACT
Objective:The 11?-hydroxysteroid dehydrogenase(11?-HSD) plays an important role in tumor biological behavior,and the 11?-HSD inhibitor Glycyrrhetinic acid(GA) may have an anticancer effect,although its mechanism remains unkown.This study aimed to observe the expressions of 11?-HSD 1 and 2 in colorectal cancer and the effects of glucocorticoid and GA on colorectal cancer cells.Methods: The mRNA expressions of 11?-HSD1 and 2 in the human colorectal cancer cell line HCT-8 were detected by reverse transcription polymerase chainreaction(RT-PCR),and the protein expressions of 11?-HSD1 and 2 were detected by Western blot.The inhibition of the growth of the HCT-8 cells was determined by MTT assay after treated with glucocorticoid,cosubstrate,GA only or their combination.Results: The expression of 11?-HSD2 mRNA and proteins but not that of 11?-HSD1 mRNA and proteins was expressed in the HCT-8 cells.The rate of cell growth inhibition was(40.87 ? 1.47)% after a 12-hour treatment with cortisol,and it was(5.79 ? 0.20)% in the cortisol + NAD group,with statistically significant difference(P
