The incidence of papillary thyroid microcarcinoma (PTMC) is steadily rising. Although conventional thyroid surgery techniques are well-established, they present challenges such as functional impairment and overtreatment. Cellular-level fluorescence-guided imaging technology (EndoSCell^®) enables precise intraoperative tumor localization and real-time identification of neurovascular structures via high-resolution imaging and targeted labeling. This technology significantly improves surgical precision, reduces the incidence of postoperative complications including recurrent laryngeal nerve injury and hypoparathyroidism, and strengthens standards for functional preservation. This article aimed to systematically explore recent advances in the application of EndoSCell^® for PTMC management, analyze its influence on the innovation of surgical approaches and the enhancement of functional preservation criteria, and discuss future directions, thereby providing a theoretical basis for clinical practice.

Objective:To investigate the short-term efficacy of bevacizumab combined with chemotherapy in patients with advanced cervical cancer, as well as its effects on tumor markers and immune function.Methods:A retrospective analysis was conducted on 60 patients with advanced cervical cancer who received treatment at Yiwu Central Hospital from January 2020 to March 2024. The patients were divided into an observation group and a control group ( n = 30 per group) based on whether they received bevacizumab. Patients in the observation group received bevacizumab in combination with chemotherapy, while those in the control group received chemotherapy alone. The two groups were evaluated over two consecutive treatment cycles, with each cycle lasting 21 days. Short-term efficacy was compared between the two groups. The Karnofsky score, tumor markers, and immune function were assessed before and after treatment in both groups. Additionally, the incidence of adverse reactions was compared between the two groups. Results:The objective response rate in the observation group was significantly higher than that in the control group [73.33% (22/30) vs. 46.67% (14/30), χ2 = 4.44, P<0.05]. After treatment, the Karnofsky score in the observation group was significantly higher than that in the control group [(83.39 ± 4.43) vs. (75.48 ± 4.06), t = 7.21, P<0.001]. The serum levels of carbohydrate antigen 125, carcinoembryonic antigen, and carbohydrate antigen 19-9 in the observation group were all significantly lower than those in the control group ( t = -11.27, -8.91, -13.33, all P<0.001). CD 3+, CD 4+, and CD 4+/CD 8+ were significantly higher in the observation group compared with the control group ( t = 10.20, 10.74, 10.17, all P<0.001). The incidence of adverse reactions did not differ significantly between the two groups (all P>0.05). Conclusions:In patients with advanced cervical cancer, bevacizumab combined with chemotherapy demonstrates better efficacy than chemotherapy alone. The combined therapy is more effective in lowering serum levels of carbohydrate antigen 125, carcinoembryonic antigen, and carbohydrate antigen 19-9, as well as enhancing immune function, without increasing adverse reactions compared with chemotherapy alone.

Objective:To investigate the correlation between transabdominal bowel ultrasongraphy (TBUS) parameters and disease activity of ulcerative colitis (UC).Methods:The results of TBUS, endoscopy and laboratory tests of 68 UC patients (108 examinations) who visited the Department of Gastroenterology of the Second Hospital (Eastern Campus) of Hebei Medical University From January 2022 to February 2024 were retrospectively analyzed. According to Mayo endoscopic score (MES), there were 10 cases of remission (MES=0) and 98 cases of active phase (MES>0); patients in active phase further classified into 16 cases of mild (MES=1), 19 cases of moderate (MES=2), and 63 cases of severe (MES=3). The TAUS parameters were compared between patients in remission and active phases. Spearman rank correlation analysis was used to analyze the correlation between the TBUS parameters including bowel wall thickness (BWT), Limberg score, wall layer stratification, fat wrapping and endoscopic activity score, laboratory inflammatory indicators. Receiver operating characteristic curve (ROC) analysis was applied to evaluate the predictive efficacy of the TBUS parameters and laboratory inflammatory indicators in identifying remission under endoscopy. Independent sample t-test and Fisher′s exact probability method were used to compare the two groups. Results:The BWT of patients in remission was significantly thinner than that of patients in active phase ((2.99±0.41) mm vs. (5.66±1.57) mm, t=-5.34, P<0.001). The proportions of patients in remisson with Limberg score ≤2, normal wall layer stratification, and absence of fat wrapping were significantly higher than those of patients in active phase (10/10 vs. 34/98, 10/10 vs. 48/98, 10/10 vs. 41/98, Fisher′s exact test, P<0.001, =0.002, =0.001). BWT, Limberg score, wall layer stratification, and fat wrapping were positively correlated with MES ( r=0.676, 0.677, 0.441, and 0.493, all P<0.001). BWT and Limberg score were moderate positively correlated with C-hypersensitive reactive protein, erythrocyte sedimentation rate and fecal calprotectin (BWT: r=0.561, 0.420 and 0.458, all P<0.001; Limberg score: r=0.576, 0.469 and 0.403, all P<0.001), and were negatively correlated with serum albumin and hemoglobin (BWT: r=-0.604 and -0.453, both P<0.001; Limberg score: r=-0.573 and -0.532, both P<0.001). The results of ROC analysis showed that BWT achieved the best predictive efficacy in identifying endoscopic remission, and the best cut-off value was 3.45 mm (area under the curve was 0.972, 95% confidence interval: 0.944 to 1.000, P<0.001), with a sensitivity of 93.9% and specificity of 100.0%. Conclusions:TBUS parameters can accurately reflect disease activity in UC. It is a powerful tool for UC monitoring. The BWT<3.45 mm is the best cut-off value in prediction of endoscopic remission.

Background and purpose:Gastric-type endocervical adenocarcinoma(G-EAC)is a rare variant of endocervical adenocarcinoma,characterized by atypical clinical manifestations and elusive lesions.Due to these factors,G-EAC is prone to being missed or misdiagnosed,significantly impacting the prognosis.Lobular endocervical glandular hyperplasia(LEGH)and atypical LEGH(aLEGH)are considered to be precancerous lesions of G-EAC.These conditions also present overlapping clinical,pathologic and imaging manifestations,making it challenging to differentiate between them preoperatively.The purpose of this study was to investigate the correlation between magnetic resonance imaging(MRI)findings of cystic-solid lesions in the cervix and their underlying pathology in order to enhance the accuracy of distinguishing between LEGH and G-EAC,ultimately aiding in the early diagnosis and appropriate management of these conditions.Methods:Clinical,imaging and pathological data of 37 LEGH and 53 G-EAC patients who attended the Obstetrics and Gynecology Hospital of Fudan University from July 2016 to August 2023 were collected.Analysis was conducted using Pearson Chi-square χ2,Fisher's exact tests and so on.Multivariate analyses were performed using logistic regression.Receiver operating characteristic(ROC)curves were used for performance evaluation.Results:In this study,differences in age,symptoms,extent,size,composition,degree of enhancement,cervical stromal ring,endometrium invasion,pelvic lymph nodes enlargement,and hydrohystera were statistically significant between the two groups(P＜0.05).In the LEGH and aLEGH groups,lesions were primarily localized to the epithelial layer of the endocervical canal.These lesions were predominantly simple cystic(32/37),and the cystic walls often displayed significant enhancement(31/37).In contrast,the G-EAC group presented with lesions involving the myometrium of the uterine cervix(42/53).These lesions were characterized by a solid component in the majority of cases(52/53),a tendency for the disappearance of the cervical stromal ring(46/53).Logistic regression analysis revealed that among the MRI features,lesion composition(OR=50.064)and incomplete cervical stromal ring(OR=40.180)were significant predictors for G-EAC.ROC analysis,incorporating lesion size,composition,enhancement degree,cervical stromal ring,and endometrial involvement,yielded an area under curve(AUC)of 0.970(95%CI:0.931-1.008).Conclusion:Combining multiple MRI features of cystic-solid lesions in the cervix aids in distinguishing between LEGH and G-EAC.

OBJECTIVES: To achieve the ambitious goal of eliminating schistosome infections, the Chinese government has implemented diverse control strategies. This study explored the progress of the 2 most recent national schistosomiasis control programs in an endemic area along the Yangtze River in China. METHODS: We obtained village-level parasitological data from cross-sectional surveys combined with environmental data in Anhui Province, China from 1997 to 2015. A convolutional neural network (CNN) based on a hierarchical integro-difference equation (IDE) framework (i.e., CNN-IDE) was used to model spatio-temporal variations in schistosomiasis. Two traditional models were also constructed for comparison with 2 evaluation indicators: the mean-squared prediction error (MSPE) and continuous ranked probability score (CRPS). RESULTS: The CNN-IDE model was the optimal model, with the lowest overall average MSPE of 0.04 and the CRPS of 0.19. From 1997 to 2011, the prevalence exhibited a notable trend: it increased steadily until peaking at 1.6 per 1,000 in 2005, then gradually declined, stabilizing at a lower rate of approximately 0.6 per 1,000 in 2006, and approaching zero by 2011. During this period, noticeable geographic disparities in schistosomiasis prevalence were observed; high-risk areas were initially dispersed, followed by contraction. Predictions for the period 2012 to 2015 demonstrated a consistent and uniform decrease. CONCLUSIONS The proposed CNN-IDE model captured the intricate and evolving dynamics of schistosomiasis prevalence, offering a promising alternative for future risk modeling of the disease. The comprehensive strategy is expected to help diminish schistosomiasis infection, emphasizing the necessity to continue implementing this strategy.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Background::Homoharringtonine (HHT) is an effective anti-inflammatory, anti-viral, and anti-tumor protein synthesis inhibitor that has been applied clinically. Here, we explored the therapeutic effects of HHT in a mouse heart transplant model.Methods::Healthy C57BL/6 mice were used to observe the toxicity of HHT in the liver, kidney, and hematology. A mouse heart transplantation model was constructed, and the potential mechanism of HHT prolonging allograft survival was evaluated using Kaplan–Meier analysis, immunostaining, and bulk RNA sequencing analysis. The HHT-T cell crosstalk was modeled ex vivo to further verify the molecular mechanism of HHT-induced regulatory T cells (Tregs) differentiation. Results::HHT inhibited the activation and proliferation of T cells and promoted their apoptosis ex vivo. Treatment of 0.5 mg/kg HHT for 10 days significantly prolonged the mean graft survival time of the allografts from 7 days to 48 days ( P <0.001) without non-immune toxicity. The allografts had long-term survival after continuous HHT treatment for 28 days. HHT significantly reduced lymphocyte infiltration in the graft, and interferon-γ-secreting CD4 + and CD8 + T cells in the spleen ( P <0.01). HHT significantly increased the number of peripheral Tregs (about 20%, P <0.001) and serum interleukin (IL)-10 levels. HHT downregulated the expression of T cell receptor (TCR) signaling pathway-related genes ( CD4, H2-Eb1, TRAT1, and CD74) and upregulated the expression of IL-10 and transforming growth factor (TGF) -β pathway-related genes and Treg signature genes ( CTLA4, Foxp3, CD74, and ICOS). HHT increased CD4 + Foxp3 + cells and Foxp3 expression ex vivo, and it enhanced the inhibitory function of inducible Tregs. Conclusions::HHT promotes Treg cell differentiation and enhances Treg suppressive function by attenuating the TCR signaling pathway and upregulating the expression of Treg signature genes and IL-10 levels, thereby promoting mouse heart allograft acceptance. These findings may have therapeutic implications for organ transplant recipients, particularly those with viral infections and malignancies, which require a more suitable anti-rejection medication.
