Traditional treatment for type 1 diabetes mellitus (T1DM) primarily involves insulin replacement, yet some patients encounter issues such as significant blood glucose fluctuations, high risk of hypoglycemia, and weight gain. In recent years, the adjuvant therapeutic role of non-insulin hypoglycemic drugs in T1DM has gradually gained attention. This article reviews the mechanisms of action and clinical research progress of five types of non-insulin hypoglycemic drugs in the treatment of T1DM: amylin analogues (pramlintide), biguanides (metformin), sodium-glucose co-transporter 2 inhibitor, dipeptidyl peptidase-4 inhibitor, and glucagon-like peptide-1 receptor agonist. It is found that these drugs can enhance clinical benefits for T1DM patients by improving insulin sensitivity, delaying gastric emptying, promoting urinary glucose excretion, and regulating incretin levels, thereby reducing glycated hemoglobin levels, decreasing insulin dosage, and managing body weight. Simultaneously, these drugs also present limitations such as low patient compliance due to complex dosing regimens, increased risk of diabetic ketoacidosis, and heterogeneity in glycemic control. Future research could focus on developing individualized treatment strategies, combining pharmacogenomics with novel biomarkers to precisely identify subpopulations of patients who may benefit, and delving into the potential value of these drugs in delaying diabetic vascular complications and improving patients’ quality of life.

OBJECTIVE To explore the effect and mechanism of Zhiqiao gancao decoction (ZQGCD) on pathological angiogenesis of degenerative intervertebral disc. METHODS The rats were randomly divided into sham operation group (normal saline), model group (normal saline), hypoxia inducible factor-1α (HIF-1α) inhibitor (YC-1) group [2 mg/(kg·d), tail vein injection], and ZQGCD low-dose, medium-dose and high-dose groups [3.06, 6.12, 12.24 g/(kg·d)], with 8 rats in each group. Except for sham operation group, lumbar disc degeneration model of rat was constructed in all other groups. After modeling, they were given relevant medicine once a day, for consecutive 3 weeks. After the last medication, pathological changes and angiogenesis of the intervertebral disc tissue in rats were observed; the levels of inflammatory factors [interleukin-1β (IL-1β), IL-6, tumor necrosis factor-α (TNF-α)] and the expressions of angiogenesis-related proteins [HIF-1α, vascular endothelial growth factor (VEGF), VEGF receptor 2 (VEGFR2), angiotensin 1(Ang 1), Ang 2] in the com intervertebral disc tissue in rats were all determined. In cell experiment, the primary nucleus pulposus cells were isolated and cultured from rats, and cellular degeneration was induced using 50 ng/mL TNF-α. The cells were divided into blank control group (10% blank control serum), TNF-α group (10% blank control serum), YC-1 group (10% blank control serum+0.2 mmol/L YC-1), and 5%, 10%, 15% drug-containing serum group (5%, 10%, 15% drug-containing serum). After 24 hours of intervention, the nucleus pulposus cells were co-cultured with HUVEC. The expressions of Collagen Ⅱ, matrix metalloproteinase-3 (MMP-3) in nucleus pulposus cells were detected. HUVEC proliferation, migration and tube forming ability were detected, and the expression levels of the HIF-1α/VEGF/Ang signal axis and angiogenesis- related proteins (add MMP-2, MMP-9) in HUVEC were detected. RESULTS Animal experiments had shown that compared with model group, the positive expression of CD31 in the intervertebral disc tissues of rats in each drug group was down-regulated (P< 0.05), the levels of inflammatory factors and angiogenesis-related proteins were decreased significantly (P<0.05), and the pathological changes in the intervertebral disc were alleviated. Cell experiments had shown that compared with TNF-α group, the expression of Collagen Ⅱ in nucleus pulposus cells of all drug groups was significantly up-regulated (P<0.05), and the expression of MMP-3 was significantly down-regulated (P<0.05); the proliferation, migration and tubulogenesis of HUVEC were significantly weakened (P<0.05). The mRNA and protein expressions of HIF-1α, VEGF, Ang 2 as well as the expression of angiogenesis-related proteins (except for the expression of Ang 2 mRNA and HIF-1α, VEGFR2, Ang 2 protein in 5% drug- containing serum group) were significantly down-regulated (P<0.05). CONCLUSIONS ZQGCD may inhibit the HIF-1α/VEGF/ Ang signal axis to weaken the angiogenic ability of vascular endothelial cells, improve pathological angiogenesis in the intervertebral disc, and delay the degeneration of the intervertebral disc.

Long-term hypertension causes excessive vascular remodeling and leads to adverse cardiovascular events. Balance of ubiquitination and deubiquitination has been linked to several chronic conditions, including pathological vascular remodeling. In this study, we discovered that the expression of ubiquitin-specific protease 25 (USP25) is significantly up-regulated in angiotensin II (Ang II)-challenged mouse aorta. Knockout of Usp25 augments Ang II-induced vascular injury such as fibrosis and endothelial to mesenchymal transition (EndMT). Mechanistically, we found that USP25 interacts directly with Forkhead box O3 (FOXO3) and removes the K63-linked ubiquitin chain on the K258 site of FOXO3. We also showed that this USP25-mediated deubiquitination of FOXO3 increases its binding to light chain 3 beta isoform and autophagosomic-lysosomal degradation of FOXO3. In addition, we further validated the biological function of USP25 by overexpressing USP25 in the mouse aorta with AAV9 vectors. Our studies identified FOXO3 as a new substrate of USP25 and showed that USP25 may be a potential therapeutic target for excessive vascular remodeling-associated diseases.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

Objective :
To analyze the difference of urinary iodine level in Hashimoto thyroiditis ( HT) patients, and to explore the possible relationship between urinary iodine level and HT under different iodine nutritional sta- tus,so as to provide some references for reasonable iodine intake in HT patients.
Methods :
A total of 101 hospi- talized HT patients were selected as HT group and divided into 3 groups according to thyroid function : HT group with hyperthyroidism (41 cases) .There were 25 cases in HT group with normal thyroid function.There were 35 cases in HT combined with hypothyroidism group.In addition,30 healthy subjects were selected as control group. Serum levels of thyroid stimulating hormone(TSH) ,triiodothyronine(T3 ) ,thyroxine (T4 ) ,thyroid peroxidase an- tibody (TPOAb) and thyroglobulin antibody (ATG) were detected by chemiluminescence assay.The size and mor- phological structure of thyroid organs were examined by ultrasonography.Urinary iodine was determined by catalytic spectrophotometry with arsenic and cerium.The nutritional status of iodine was classified into iodine deficiency ( < 100 μg/ L) ,iodine adequacy( 100 -199 μg/ L) ,iodine adequacy (200 -299 μg/ L) and iodine excess ( ≥ 300 μg/ L) .Non-parametric test was used to compare urinary iodine level between HT group and control group,one- way ANOVA and t test were used to compare urinary iodine level between HT group and control group ,and Spearman correlation analysis was used to compare the correlation between urinary iodine level and T3 ,T4 ,TSH, ATG and TPOAb under different iodine nutrition status.
Results :
Compared with control group,ATG and TPOAb levels in HT group increased (P<0. 001) ,and urinary iodine levels increased (P<0. 05) ,with statistical signifi- cance.Compared with the control group in different thyroid function states,only the HT group with hypothyroidism increased the urinary iodine level (P<0. 01) ,and the difference was statistically significant.Spearman correlation analysis showed that urine iodine level was positively correlated with ATG and TPOAb levels in iodine excess condi- tion (P<0. 05) ,and urine iodine level was positively correlated with TSH level in iodine sufficient condition and iodine excess condition in HT patients (P<0. 05) .
Conclusion
The urinary iodine level of HT patients was high- er than that of normal people.When the urinary iodine level of residents is ≥ 300 μg/ L,iodine intake is prone to HT.When the urinary iodine level of HT patients is ≥ 200 μg/ L,iodine consumption is prone to hypothyroidism, and iodine intake should be limited.

Objective:To investigate the value of digital medical 3D technology versus traditional 2D technology in the diagnosis and treatment of solid abdominal tumors in children. Methods:A total of 80 children with solid abdominal tumors who received surgical treatment guided by digital medical 3D technology at Guigang People's Hospital from January 2018 to January 2022 were included in the observation group. An additional 80 children with solid abdominal tumors who received surgical treatment guided by traditional 2D technology at the same hospital from January 2014 to December 2017 were included in the control group. Clinical efficacy was compared between the two groups.Results:The surgical time, intraoperative blood loss, postoperative exhaust time, postoperative hospital stay in the observation group were (111.8 ± 28.9) minutes, (26.8 ± 25.2) mL, (2.2 ± 1.2) days, (7.5 ± 1.4) days, respectively, which were significantly shorter or less than those in the control group [(193.1 ± 66.0) minutes, (86.2 ± 47.0) mL, (3.7 ± 0.9) days, (12.2 ± 3.5) days, t = 7.00, 6.88, 5.87, 7.53, all P < 0.05]. The complete surgical resection rate in the observation group was significantly higher than that in the control group [92.5% (74/80) vs. 81.3% (65/80), χ2 = 4.44, P < 0.05]. The incidence of complications in the observation group was significantly lower than that in the control group [6.3% (5/80) vs. 16.3% (13/80), χ2 = 4.00, P < 0.05]. Conclusion:The utilization of digital medical 3D technology in the surgical treatment of solid abdominal tumors in children can markedly decrease surgical time, reduce intraoperative blood loss, promote postoperative recovery, achieve a high surgical resection rate, and minimize postoperative complications.

Sepsis is a life-threatening organ dysfunction due to dysregulation of the body's response to infection. The immunosuppressive phase of sepsis is also an important cause of high morbidity and mortality in patients with advanced sepsis. Myeloid-derived suppressor cell (MDSC), as a heterogeneous population of Gr1 +CD11b + immature cells, play a pivotal role in the immune process of advanced sepsis together with programmed death-1 (PD-1) and programmed death-ligand 1 (PD-L1) with immunosuppressive properties. This review summarized the research progress of PD-1/PD-L1 pathway-mediated mechanism of MDSC in septic immunosuppression in recent years. The mechanism of action of PD-1/PD-L1 pathway in the immunosuppressive stage, the effects of PD-1/PD-L1 pathway on the "dual-signaling" model of MDSC through the signaling pathway and cytokines, as well as the time course of PD-1/PD-L1 pathway mediation in sepsis were described.

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

BACKGROUND:MicroRNA(miRNA)levels are closely related to cell apoptosis and proliferation,extracellular matrix metabolism and inflammatory response in intervertebral disc cells.However,the specific role of miR-142-3p in lumbar intervertebral disc degeneration remains unclear. OBJECTIVE:To investigate the correlation between the expression of miRNA-142-3p,mixed lineage kinase 3 and interleukin-1β in nucleus pulposus tissue and degree of human lumbar intervertebral disc degeneration. METHODS:A total of 82 patients with lumbar intervertebral disc degenerative diseases in Suzhou Ninth People's Hospital from January 2020 to March 2022 were collected as the study subjects,all of whom underwent MRI examination before operation.According to the Videman classification,the patients were divided into mild degeneration group(n=36),moderate degeneration group(n=26)and severe degeneration group(n=20).Eighty-two specimens of the nucleus pulposus were obtained.The mRNA expression of miRNA-142-3p as well as the mRNA and protein expression of mixed lineage kinase 3,interleukin-1β,type I collagen,type II collagen in nucleus pulposus tissue were detected by qPCR and western blot assay.The correlation between the degree of human lumbar intervertebral disc degeneration and the expression levels of miRNA-142-3p,mixed lineage kinase 3,and interleukin-1β was also assessed using the Spearman correlation coefficient method.Thirty adult Sprague-Dawley rats were divided into sham-operated group(executed after puncturing skin and muscle only),mild degeneration group(executed 1 week after puncturing Co7/8 segments)and severe degeneration group(executed 2 weeks after puncturing Co7/8 segments),with 10 rats in each group.After that,we detected the protein expression of mixed lineage kinase 3 and interleukin-1β as well as the gene expression of miRNA-142-3p,mixed lineage kinase 3 and interleukin-1β in the nucleus pulposus tissue. RESULTS AND CONCLUSION:In human nucleus pulposus tissue,the miRNA-142-3p expression ranked from high to low as follows:mild degeneration group>moderate degeneration group>severe degeneration group(P<0.05);the gene and protein expression of mixed lineage kinase 3 and interleukin-1β from low to high was as follows:mild degeneration group

Objective To investigate the reasons for the inconsistent results between the vertical auto profile(VAP)method and bio-chemical homogeneous phase(BHP)method in detecting plasma low-density lipoprotein cholesterol(LDL-C),and provide experimen-tal basis for the accurate and quantitative detection of plasma LDL-C levels.Methods A total of 360 plasma samples from diabetes mellitus patients combined with carotid plaque admitted to the Department of Endocrinology of Ningbo Yinzhou Hospital of Traditional Chinese Medicine during January,2022 and January,2023 were collected.The LDL-C levels of these samples were detected by the VAP method and BHP method,respectively.The VAP method uses software to automatically calculate the area under the LDL-C curve after centrifugation of the sample as the LDL-C level(LDL-CVAP)and the BHP method directly detects the LDL-C level(LDL-CBHP)by the special surfactant method.360 samples were divided into the consistent group(group A)and inconsistent group(group B)ac-cording to the relative deviation between the LDL-CBHP and LDL-CVAP methods.Group B was further divided into the LDL-CBHP on the high side group(Group B1)and LDL-CBHP on the low side group(Group B2).Groups B1 and B2 were divided into B1-1,B1-2,B1-3 and B2-1 groups based on the degree of relative deviation.The percentages of samples and levels of lipoprotein a cholesterol[Lp(a)-C],intermediate-density lipoprotein cholesterol(IDL-C),Lp(a)-C and IDL-C[Lp(a)-C+IDL-C],very low-density lipo-protein cholesterol(VLDL-C),total cholesterol(TC)and total triglyceride(TG)in each group were compared.Results The LDL-CBHP levels of 360 samples were significantly higher than that of LDL-CVAP(P<0.01).The percentage of samples in group B was significantly higher than that in group A,and that of group B1 was significantly higher than that of group B2(P<0.05).The levels of Lp(a)-C,IDL-C and Lp(a)-C+IDL-C in groups B1-1,B1-2,and B1-3 were significantly higher than those in group A(P<0.01).The relative deviation between LDL-CBHP and LDL-CVAP in 360 samples was significantly positively correlated with the levels of Lp(a)-C,IDL-C,and Lp(a)-C+IDL-C(P<0.01).The maximum correlation coefficient was found in Lp(a)-C+IDL-C.Conclusion The results of plasma LDL-C in diabetes mellitus patients combined with carotid plaque detected by the BHP method are significantly different from those detected by the VAP method,which mainly shows that the results of the BHP method are on the high side.The higher the level of plasma Lp(a)-C+IDL-C,the greater the relative deviation between the BHP method and VAP method.The reason for the high results of LDL-C detected by the BHP method may be related to the fact that LDL-CBHP contains irremovable Lp(a)-C and cholesterol carried by IDL-C.The VAP method can be used as an accurate method for detecting real LDL-C without Lp(a)-C and IDL-C.
