Tumor cells use glycolysis to provide material and energy under hypoxic conditions to meet the energy requirements for rapid growth and proliferation, namely the Warburg effect. Even under aerobic conditions, tumor cells mainly rely on glycolysis to provide energy. Therefore, glucose transporter protein 1(GLUT1), which is involved in the process of glucose metabolism, plays an important role in tumorigenesis, development and drug resistance, and is considered to be one of the important targets in the treatment of malignant tumors. In recent years, research on tumor glucose metabolism has gradually become a hot spot. It has been shown that various factors are involved in the regulation of tumor energy metabolism, among which the role of GLUT1 is the most critical. In this paper, the authors reviewed the latest research progress of GLUT1-targeted traditional Chinese medicine(TCM) active ingredient nano-delivery system in tumor therapy, aiming to reveal the feasibility and effectiveness of this system in the delivery of chemotherapeutic drugs. The GLUT1-targeted TCM active ingredient nano-delivery system can overcome the bottleneck of the traditional targeting strategy as well as the high-permeability long retention(EPR) effect. In summary, the authors believe that the GLUT1-targeted TCM active ingredient nano-delivery system provides a new strategy for targeted treatment of tumors and has a broad application prospect in tumor prevention and treatment.

Objective:To evaluate the development of fetal cerebral sulci and gyrus and the blood perfusion in pregnant women with gestational diabetes mellitus(GDM) by ultrasound.Methods:A total of 1 540 pregnant women with 28-34 weeks of pregnancy who underwent systematic screening in Henan Provincial People′s Hospital from January 2022 to October 2022 were prospectively selected, 100 pregnant women with GDM were selected as the GDM group. According to the effect of blood glucose control, the GDM group was divided into 2 groups: the satisfied control group (GDM group 1), and the dissatisfied control group (GDM group 2), with 50 cases in each group. At the same period, 50 healthy pregnant women at 28-34 weeks of gestation were enrolled as the control group. The differences of the sylvian fissure, parietooccipital sulci, calcarine sulci and cinguli sulci among the 3 groups were statistically analyzed. And the correlations between the deep of the brain cerebral sulci and gyrus and controlled blood glucose levels were evaluated. The umbilical artery pulsation index(UAPI), middle cerebral artery pulsation index(MCAPI) and ductus venosus pulsation index(DVPI) among the 3 groups were compared, and the differences in fetal blood perfusion among the 3 groups were evaluated.Results:There were no significant differences in the depths of the sylvian fissure, parietooccipital sulci, calcarine sulci and cinguli sulci between the control group and the GDM group 1 (all P>0.05), and they were larger than those of the GDM group 2 (all P<0.05). The depths of lateral fissure, parieto-occipital sulcus, cingulate sulcus and calcarine sulcus were negatively correlated with fasting blood glucose, 1 h and 2 h postprandial blood glucose (all P<0.05). There were no significant differences in MCAPI, UAPI and DVPI between the control group and GDM1 group (all P>0.05). The MCAPI in GDM 2 group was lower than that in the control group and GDM 1 group, and the UAPI and DVPI values were higher than those in the control group and GDM1 group(all P<0.05). Conclusions:The maturity of fetal cerebral sulci and gyrus in GDM pregnant women is related to the blood glucose control of pregnant women. The change of blood perfusion caused by persistent hyperglycemia in pregnant women and intrauterine hypoxia may cause the development retardation of cerebral sulci and gyrus.

Objective:To investigate the efficacy and mechanism of canagliflozin (Cana) in the treatment of high glucose-induced human podocyte (HPC) injury.Methods:The HPCs were divided into 5 groups: normal glucose group (NG group), mannitol group (MA group), high glucose group (HG group), Cana low dose (0.3 μmol/L) group and Cana high dose (1.0 μmol/L) group. Western blotting was used to examine the protein expressions of membrane-associated guanylate kinase inverted-2 (MAGI2), podocyte-associated protein nephrin, sodium-glucose transporter 2 (SGLT2), NOD-like receptor thermal protein domain associated protein 3 (NLRP3), apoptosis- associated speck-like protein containing a CARD (ASC), and cleaved-caspase1 in podocytes. Phalloidin staining of F-actin in podocytes was used to observe cytoskeletal injury. Intracellular reactive oxygen species (ROS) level of HPC was detected by the 2',7'-dichlorodihydrofluorescein diacetate (DCFH-DA) probe. Levels of interleukin (IL)-18 and IL-1β in culture medium of podocytes were detected by enzyme-linked immunosorbent assay (ELISA).Results:(1) Compared with the NG group, the protein expressions of MAGI2 and nephrin decreased (both P<0.01), the protein expression of SGLT2 increased ( P<0.01), the changes of cell morphology and cytoskeleton remodeling were obvious, intracellular ROS level increased ( P<0.01), while NLRP3, ASC and cleaved-caspase1 protein expressions decreased in the HG group (all P<0.01). The results of ELISA showed that IL-18 and IL-1β concentrations were higher in the HG group (both P<0.05). (2) Compared with the HG group, in the Cana groups, MAGI2 and nephrin expressions up-regulated (both P<0.01), the changes of cell morphology and cytoskeleton remodeling were alleviated. Meanwhile the Cana groups showed decreased SGLT2 expression ( P<0.05), lower ROS level, down- regulated NLRP3, ASC, cleaved-caspase1 expressions (all P<0.01), and decreased concentrations of IL-18 and IL-1β in culture medium of podocytes (both P<0.05). Conclusion:Cana can improve high glucose-induced injury and inflammation in human podocyte, possibly due to the repression of the ROS/NLRP3 signaling pathway.

Objective:To observe any effect of repetitive transcranial magnetic stimulation (rTMS) on sleep disorders among children with cerebral palsy (CP).Methods:A total of 102 children with CP and disordered sleep were randomly divided into an experimental group and a control group, each of 51. All were given routine rehabilitation and sleep health education, but the experimental group additionally received rTMS for two weeks. The polysomnography (PSG) results of the two groups were recorded and analyzed.Results:The PSG parameters had improved greatly in both groups after the treatment. The percentage of N2 sleep (depth of sleep during light sleep) in the severe cerebral palsy group and of N3 sleep (depth of sleep during deep sleep) in the moderate cerebral palsy group had increased significantly more than in the mild cerebral palsy group, on average. After the intervention the percentages of N2 and N3 in those with mixed cerebral palsy and of N3 in those with involuntary motor cerebral palsy had increased significantly more than in those with spastic cerebral palsy, on average.Conclusion:rTMS treatment can improve the sleep disorders of children with cerebral palsy, especially N2 sleep among children with moderate to severe cerebral palsy, N3 sleep in cases of mixed or dyskinetic CP.

Objective:To evaluated the clinical efficacy of a reduced-intensity preconditioning regimen for single non-blood-related umbilical cord blood transplantation (sUCBT) in the treatment of severe aplastic anemia (SAA) .Methods:The clinical data of 63 patients with SAA who underwent sUCBT from January 2021 to July 2023 at the Department of Hematology of the First Affiliated Hospital of USTC were retrospectively analyzed. Fifty-two patients received total body irradiation/total bone marrow irradiation (TMI) combined with fludarabine or a cyclophosphamide- conditioning regimen (non-rATG group) , while 11 patients received rabbit anti-human thymocyte immunoglobulin (rATG) combined with TMI, fludarabine, or the cyclophosphamide-conditioning regimen (rATG group) . All patients received cyclosporine A and mycophenolate mofetil for graft-versus-host disease (GVHD) prophylaxis. Complications post-transplantation and long-term survival were compared between the two groups.Results:The baseline parameters were balanced between the two groups ( P>0.05) . In the rATG group, all patients achieved stem cell engraftment, and in the non-rATG group, five patients had primary graft failure. There was no significant difference in the cumulative incidence of neutrophil engraftment at 42 days after transplantation or platelet engraftment at 60 days between the two groups. The incidence of grade Ⅱ-Ⅳ acute GVHD in the rATG group was significantly lower than in the non-rATG group (10.0% vs. 46.2% , P=0.032) , and the differences in the cumulative incidences of grade Ⅲ/Ⅳ acute GVHD and 1-year chronic GVHD were not statistically significant ( P=0.367 and P=0.053, respectively) . There were no significant differences in the incidences of pre-engraftment syndrome, bacterial bloodstream infections, cytomegalovirus viremia, or hemorrhagic cystitis between the two groups ( P>0.05 for all) . The median follow-up time for surviving patients was 536 (61-993) days, and the 1-year transplantation related mortality (TRM) of all patients after transplantation was 13.0% (95% CI 6.7% -24.3% ) . Among the patients in the non-rATG and rATG groups, 15.5% (95% CI 8.1% -28.6% ) and 0% ( P=0.189) , respectively, had mutations. The 1-year overall survival (OS) rate of all patients after transplantation was 87.0% (95% CI 75.7% -93.3% ) . The 1-year OS rates in the rATG group and non-rATG group after transplantation were 100% and 84.5% , respectively (95% CI 71.4% -91.9% ) ( P=0.198) . Conclusion:The preliminary results of sUCBT with a low-dose irradiation-based reduced-intensity conditioning regimen with fludarabine/cyclophosphamide for the treatment of patients with SAA showed good efficacy. Early application of low-dose rATG can reduce the incidence of acute GVHD after transplantation without increasing the risk of implantation failure or infection.

Objective:To analyze the genetic sequences of two patients with a rare Ael blood subgroup.Methods:Two female patients undergoing treatment respectively for adenomyoma of the uterus and gastritis at the Second Affiliated Hospital, Yuying Children′s Hospital of Wenzhou Medical University in June 2019 and September 2020 were selected as the study subjects. Their Ael subtypes were identified with a saline tube agglutination assay and absorption-emission assay. Sequence of the ABO gene Ael subtypes was determined by the Sanger method. The impact of genetic variants on the structural stability of N-acetylgalactosaminyl transferase (GTA) was analyzed with PyMOL software by constructing a structure predicted model. Results:Both patients were determined as Ael blood subgroup. Sequencing result of patient 1 was ABO* O.01.02/ ABO* O.01.02, which has resulted in a p. Thr88Profs*31 amino acid substitution. The sequencing result of patient 2 was ABO* Ael.06/ ABO* O.01.02, in which c. 425C>T and c. 467C>T variants in exon 7 have led to p. Met142Thr and p. Pro156Leu substitutions. Prediction of the protein model speculated that the p. Met142Thr not only can change the binding of GTA protein with water molecules, but also the local hydrogen bond network of GTA, which may lead to decreased enzymatic activity. By contrast, the p. Pro156Leu variant has trivial effect on the structural stability of GTA. Conclusion:The molecular structure of Ael subtypes can be diverse. The genotypes of the two patients have been respectively determined as ABO* O.01.02/ ABO* O.01.02 with a G261 deletion and ABO* Ael.06/ ABO* O.01.02.

Objective:To investigate the value of CT quantitative parameters of tumor and spleen in predicting the clinical stage of gastric cancer (Ⅰ/Ⅱ stage and Ⅲ/Ⅳ stage).Methods:This study was a case-control study. The data of 145 patients with gastric cancer confirmed by pathology in the First Affiliated Hospital of Zhengzhou University from February 2019 to June 2021 were retrospectively collected, including 70 cases of Ⅰ/Ⅱ stage and 75 cases of Ⅲ/Ⅳ stage. On the baseline CT images, the tumor related parameters, including tumor thickness, length of tumor, CT attenuation of tumor unenhanced phase, CT attenuation of tumor arterial phase, CT attenuation of tumor venous phase were measured. The spleen related parameters, including splenic thickness, CT attenuation of splenic unenhanced phase, CT attenuation of splenic arterial phase, CT attenuation of splenic venous phase, and standard deviation of CT attenuation (CTsd) in splenic unenhanced phase were also measured. The independent sample t test or Mann-Whitney U test was used to compare the parameters between the Ⅰ/Ⅱ stage and Ⅲ/Ⅳ stage patients. The multi-factor logistic regression analysis was used to find the independent predictors of gastric cancer clinical stage, and establish the combined parameters. The efficiency to the diagnosis of gastric cancer stage of single and combined parameters was evaluated using the operating characteristic curve, and the DeLong test was used to compare the differences of area under the curve (AUC). Results:There were significant differences in tumor thickness, length of tumor, CT attenuation of tumor venous phase, CT attenuation of splenic unenhanced phase, CT attenuation of splenic venous phase, CTsd in splenic unenhanced phase between the Ⅰ/Ⅱ stage and Ⅲ/Ⅳ stage of gastric cancer ( P<0.05). Multivariate analysis showed that tumor thickness ( OR=1.073, 95% CI 1.026-1.123, P=0.002), CT attenuation of splenic venous phase ( OR=1.040, 95% CI 1.011-1.070, P=0.006) and CTsd in splenic unenhanced phase ( OR=1.625, 95% CI 1.330-1.987, P<0.001) were independent risk factors for the clinical stage of gastric cancer and the combined parameters were established. The AUC values of tumor thickness, CT attenuation of splenic venous phase, CTsd in splenic unenhanced phase and combined parameters were 0.655, 0.614, 0.749 and 0.806, respectively. The AUC of combined parameters was higher than those of tumor thickness and CT attenuation of splenic venous phase, and the differences were statistically significant ( Z=3.37, 3.82, both P<0.001). Conclusion:Tumor thickness, CT attenuation of splenic venous phase and CTsd in splenic unenhanced phase are independent risk factors for the clinical stage of gastric cancer, and combined parameters can improve the diagnostic efficiency.

Objective:To analyze the CT and MRI imaging features of Kimura disease in parotid region.Methods:This study was a cross-sectional study. From January 2018 to June 2023, a total of 40 patients with Kimura disease in parotid region who were initially diagnosed and confirmed by postoperative pathology were retrospectively collected in the Ninth People′s Hospital, School of Medicine, Shanghai Jiao Tong University. There were 36 male patients and 4 female patients, with an age of (46±19) years, ranging from 8 to 74 years old. The clinical data, preoperative CT and MRI findings were analyzed. For patients undergoing MRI examination, the apparent diffusion coefficient (ADC) value of the lesion was measured, and the type of time-signal intensity curve (TIC) was analyzed.Results:The ratio of male to female patients was 9∶1, with a long clinical history (1 month to 20 years). And 37 cases (37/40, 92.5%) were associated with elevated peripheral blood eosinophils. Among the 40 cases, there were 4 cases of nodular type, 34 cases of diffuse type, and 2 cases of intermediate type. Nodular type: All lesions were located in the superficial lobe of unilateral parotid gland, and 3 cases had multiple lesions. The lesions were round, well-defined, and homogeneous in density or signal intensity. Two lesions showed hyperintensity on T 2WI and obvious homogeneous enhancement. The TIC was plateau type, and the ADC values were 0.74×10 -3 mm 2/s and 0.82×10 -3 mm 2/s. Diffuse type: The 22 cases had multiple lesions, and 20 cases had subcutaneous lesions in other parts of the head and neck. The lesions were irregular in shape and ill-defined in boundary. The adjacent subcutaneous tissue and skin were involved in 33 cases. The density or signal intensity of the lesions was heterogeneous, and among the 15 patients who underwent MRI, 14 cases showed uneven slightly hyperintensity with hypointense strips on T 2WI, moderate or significant enhancement. TIC showed a persistent pattern in 9 cases, and a plateau pattern in 6 cases. The ADC value was (0.99±0.21)×10 -3 mm 2/s. Intermediate type: The 2 cases were single, irregular in shape, without involvement of adjacent subcutaneous tissue and skin, with obvious enhancement and no necrosis. And 28 cases of diffuse type and 2 cases of nodular type were accompanied by ipsilateral or bilateral cervical lymphadenopathy. The enlarged lymph nodes had clear boundaries, homogeneous density or signal intensity, and homogeneous enhancement. Conclusions:The Kimura disease in parotid region has a long clinical course and elevated peripheral blood eosinophils. The diffuse type is more common in the morphology, with multiple ill-defined lesions in and around the parotid gland, and can be accompanied by similar subcutaneous lesions in other parts of the head and neck with obvious enhancement, accompanied by cervical lymph node enlargement. TIC shows persistent pattern or plateau type, and the ADC value is low. The nodular type and intermediate type are rare.
