Objective To explore the significance of mitoxantrone hydrochloride injection and carbon nanoparticles suspension injection in endoscopic radical thyroid cancer surgery.Methods A retrospective analysis was carried out on patients who underwent endoscopic radical surgery for unilateral thyroid cancer at the Depart-ment of General Surgery,Gansu Provincial Central Hospital,from December 2022 to February 2024.The patients were classified into two groups according to the intraoperative tracer employed:the mitoxantrone group and the nanocarbon group.After a 6-month postoperative follow-up,the baseline data of the two patient groups were compared.The intraoperative visualization of lymph nodes and parathyroid glands in both groups was observed.Additionally,the hospitalization costs and the incidence of postoperative complications were compared between the two groups.Results In this study,110 cases were included in the Mitoxantrone group and 126 cases in the nanocarbon group.The staining time of the central lymph nodes was significantly shorter in the nanocarbon group compared to the mitoxantrone group(P<0.05).The blue staining rate of MHI reached 97.5%,while the black staining rate of CNSI was 98.3%.The difference between them was not statistically significant(P>0.05).Regarding the number of central lymph nodes dissected,it was 9.34±0.22 in the Mitoxantrone group and 9.88±0.24 in the nanocarbon group,with no statistically significant difference(P>0.05).Similarly,the parathyroid misdissection rates were 1.8%and 0.8%in the two groups respectively,and no significant statistical difference was observed(P>0.05).Postoperative blood calcium and PTH levels measured at 1 day,1 month,and 6 months did not show any statistically significant differences between the two groups(P>0.05).The incidence of transient hypoparathy-roidism and hypocalcemia was comparable in both groups(P>0.05),and no patients developed permanent hypo-parathyroidism or permanent hoarseness.None of the patients in one Mitoxantrone group experienced postoperative hemorrhage,coeliac leakage,or skin staining.In contrast,in the nanocarbon group,there was one case of postop-erative hemorrhage and one case of coeliac leakage,and two case of skin staining.Conclusions In laparoscopic unilateral thyroid cancer radical surgery,when it comes to lymph node tracing and parathyroid gland protection,no significant disparities were detected between MHI and CNSI.Nevertheless,CNSI exhibits a shorter staining time for central lymph nodes.In contrast,MHI is more manageable,features a faster metabolic rate,and has been demonstrated to be more cost-effective.

Objective:This study aimed to systematically evaluate the efficacy of glucagon-like peptide-1(GLP-1) receptor agonists and multi-target analogs on weight reduction and cardiometabolic outcomes in non-diabetic individuals with obesity, and to compare the efficacy and safety across different GLP-1 receptor agonists.Methods:Randomized controlled trials(RCTs) published between January 2000 and March 2025 were identified through a systematic search of CNKI, Wanfang, Web of Science, PubMed, and Cochrane databases. Two reviewers independently screened the studies, extracted data, and assessed methodological quality. Meta-analysis was performed using RevMan 5.4.1 software. Results:A total of 16 RCTs involving 11 032 non-diabetic individuals with obesity were included. Meta-analysis showed that GLP-1 receptor agonists significantly reduced body weight(ΔWeight=-8.71 kg, 95% CI -10.68 to -6.74, P<0.001) and BMI(ΔBMI=-3.01 kg/m 2, 95% CI -3.77 to -2.25, P<0.001), as well as improved systolic blood pressure(ΔSBP=-4.13 mmHg, 1 mmHg=0.133 kPa, 95% CI -4.87 to -3.39, I2=60%) and diastolic blood pressure(ΔDBP=-1.39 mmHg, 95% CI -2.32 to -0.46, I2=95%). Tirzepatide showed the most pronounced effects on both weight and blood pressure reduction. In addition, GLP-1 receptor agonists significantly lowered LDL-C, TC, and TG, while moderately increasing HDL-C levels. In terms of safety, GLP-1 receptor agonists were associated with an increased risk of gastrointestinal adverse events, but did not significantly increase the risk of hypoglycemia. Conclusion:GLP-1 receptor agonists are effective in reducing weight, BMI, and blood pressure, and in improving lipid profiles in non-diabetic individuals with obesity. However, gastrointestinal side effects should be closely monitored. Given the variability in efficacy and safety among various GLP-1 receptor agonists, personalized treatment approaches are recommended.

Objective:To analyse the differences of related genes between serum alpha-fetoprotein (AFP) positive gastric cancer and AFP negative gastric cancer, and the relationship between related genes and prognosis of serum AFP positive gastric cancer.Methods:A total of 1 144 gastric cancer patients undergoing surgery at the 940th Hospital , Joint Logistic Support Force, People's Liberation Army from Jan 2013 to Dec 2018 were retrospectively analyzed. Of them, 47 cases were of AFP positive gastric cancer, and 47 serum AFP negative case were obtained by proper matching method.Results:Forty-seven patients with serum AFP positive gastric cancer, accounting for 4.1% of all gastric cancer patients during the same period. The prognosis of serum AFP negative gastric cancer is better than that of serum AFP positive gastric cancer. The 1-, 3- and 5-year cumulative survival rates were 95.6% vs. 63.8%, 48.9% vs. 23.4% and 26.7% vs. 14.9%, respectively. There were statistical differences in the immunohistochemistry of AFP, HER2, VEGF, GPC3, SALL4, P53 and Ki67 between the two groups ( χ2=67.758, P<0.001; χ2=4.004, P=0.044; χ2=19.299, P<0.001; χ2=5.232, P=0.022; χ2=6.359, P=0.012; χ2=6.224, P=0.013; χ2=5.232, P=0.022). The more co-positive expressions of AFP, GPC3, VEGF and SALL4, the more likely they were to affect pTNM stage, vascular invasion and liver metastasis ( χ2=5.328, P=0.021; P=0.013; χ2=5.887, P=0.015; χ2=3.923, P=0.048). Univariate and multivariate survival analysis of serum AFP positive gastric cancer showed:AFP, GPC3, VEGF and SALL4 were risk factors for AFP positive gastric cancer ( HR=3.700, P=0.036; HR=4.237, P=0.003; HR=3.916, P=0.004; HR=3.412, P=0.001). Conclusions:Serum AFP positive gastric cancer is a rare and highly invasive special type of gastric cancer. AFP, GPC3, VEGF and SALL4 are overexpressed in serum AFP positive gastric cancer, which is correlated with tumor stage, vascular invasion and liver metastasis. The final diagnosis of serum AFP positive gastric cancer still needs immunohistochemical examination. Preoperative serum AFP level is an important basis for AFP positive gastric cancer screening and AFP immunohistochemical examination.

In clinical dentistry,addressing unique conditions such as tilted,elongated,and torsion teeth during prepa-ration can be effectively managed through digital tooth morphology design.The production of a multi-stage 3D-printed guide offered a more efficient and accurate solution.This article presented a case of significant inclination,elongation,and torsion in the maxillary and mandibular canines that were successfully treated using crown restoration modification.A crown preparation guide was fabricated based on the final form design of the restoration using the target restorative space analysis technique to ensure precise tooth preparation.A tooth preparation guide was also designed and utilized fur-ther to enhance accuracy and efficiency during complex tooth preparation.The combined application of these multi-stage guides demonstrated promising clinical prospects.

Objective:To observe the effect of acupuncture in the treatment of accommodative myopia in children.Methods:A total of 76 children with accommodative myopia who met the inclusion criteria were divided into a control group or a test group according to the random number table method,with 38 cases in each group.The control group was given education on eye hygiene,and the test group was treated with acupuncture twice a week for 2 months in addition to the intervention used in the control group.The patient's uncorrected visual acuity(UCVA),refraction,and axial length(AL)were measured before treatment and 1 month and 2 months after treatment.Results:After 1 month of treatment,there was no significant difference in the UCVA between the two groups(P＞0.05);after 2 months of treatment,the UCVA of the test group was better than that of the control group(P＜0.05).After 1 and 2 months of treatment,the refraction of the two groups was significantly different from that before treatment(P＜0.01),but there was no significant difference between the two groups(P＞0.05).After 1 and 2 months of treatment,the AL in the control group was increased compared with that before treatment(P＜0.05),while there was no significant change in the test group(P＞0.05),and there was no significant difference between the two groups(P＞0.05).Conclusion:Acupuncture treatment can improve UCVA in children with accommodative myopia.

The condition of patients with severe traumatic brain injury (sTBI) complicated by corona virus 2019 disease (COVID-19) is complex. sTBI can significantly increase the probability of COVID-19 developing into severe or critical stage, while COVID-19 can also increase the surgical risk of sTBI and the severity of postoperative lung lesions. There are many contradictions in the treatment process, which brings difficulties to the clinical treatment of such patients. Up to now, there are few clinical studies and therapeutic norms relevant to sTBI complicated by COVID-19. In order to standardize the clinical treatment of such patients, Critical Care Medicine Branch of China International Exchange and Promotive Association for Medical and Healthcare and Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Chinese expert consensus on clinical treatment of adult patients with severe traumatic brain injury complicated by corona virus infection 2019 ( version 2023) based on the joint prevention and control mechanism scheme of the State Council and domestic and foreign literatures on sTBI and COVID-19 in the past 3 years of the international epidemic. Fifteen recommendations focused on emergency treatment, emergency surgery and comprehensive management were put forward to provide a guidance for the diagnosis and treatment of sTBI complicated by COVID-19.

With persistent advancement of surgical instruments, methods and techniques, clinical efficacy of liver transplantation has been steadily enhanced. However, the length of anhepatic phase is still an important factor affecting the efficacy of liver transplantation. Rat is one of the major animal models for liver transplantation-related basic research. In this article, multiple approaches for prolonging the anhepatic phase and shortening the operation time during anhepatic phase in rat liver transplantation were reviewed, which consisted of sevoflurane inhalation anesthesia, intravenous infusion via jugular vein indwelling needle, clamping of the abdominal aorta before anhepatic phase, injection of normal saline into portal vein before anhepatic phase, subcutaneous transposition of the spleen, electrocoagulation of hepatic esophageal artery, magnetic ring anastomosis of the superior and inferior hepatic vena cava, cannula anastomosis of the superior and inferior hepatic vena cava, stent anastomosis of the superior and inferior hepatic vena cava, rapid connection device and cannula of portal vein, and ring-shaped cannula of hepatic tissue-preserving inferior hepatic vena cava, aiming to add evidence for prolonging the duration of anhepatic phase, improving the operation efficiency during anhepatic phase and elevating the success rate of rat liver transplantation.

Alzheimer's disease (AD) is associated with the impairment of white matter (WM) tracts. The current study aimed to verify the utility of WM as the neuroimaging marker of AD with multisite diffusion tensor imaging datasets [321 patients with AD, 265 patients with mild cognitive impairment (MCI), 279 normal controls (NC)], a unified pipeline, and independent site cross-validation. Automated fiber quantification was used to extract diffusion profiles along tracts. Random-effects meta-analyses showed a reproducible degeneration pattern in which fractional anisotropy significantly decreased in the AD and MCI groups compared with NC. Machine learning models using tract-based features showed good generalizability among independent site cross-validation. The diffusion metrics of the altered regions and the AD probability predicted by the models were highly correlated with cognitive ability in the AD and MCI groups. We highlighted the reproducibility and generalizability of the degeneration pattern of WM tracts in AD.
