Type 2 diabetes mellitus(T2DM) is a prevalent metabolic and endocrine disorder. Long-term hyperglycemia can lead to severe chronic complications, imposing substantial economic burdens on both society and patients. Despite the availability of various hypoglycemic agents for clinical use, these agents often fail to meet the therapeutic needs of T2DM and its complications. Consequently, there is an urgent need for novel therapeutic strategies and drugs. Lithocarpus litseifolius(L. litseifolius), commonly referred to as "cordyceps on trees", has a long history of use in traditional medicine and can be applied in tea, sugar, and medicine. Research indicates that L. litseifolius extracts are rich in dihydrochalcones, including trilobatin, phloridzin, and phloretin, which exhibit a range of pharmacological activities, such as anti-inflammatory, antioxidant, hypoglycemic, hypolipidemic, hepatoprotective, and cardioprotective effects. These properties suggest potential applications in the treatment of T2DM and its complications. This review systematically compiled and organized the relevant literature from the past decade on dihydrochalcones(trilobatin, phloridzin, and phloretin) from L. litseifolius extracts. It highlighted recent research progress regarding their role in treating T2DM and its complications through mechanisms such as reducing insulin resistance, regulating glucose transport, improving glucose and lipid metabolism, modulating enzyme activity, regulating gut microbiota, and alleviating inflammation and oxidative damage. The purpose of this review is to provide a reference and basis for future research on the prevention and treatment of T2DM and its complications using dihydrochalcones(trilobatin, phloridzin, and phloretin) from L. litseifolius extracts.

Objective:To explore brain network properties and their relationship with cognitive function in children with spastic cerebral palsy (SCP) using diffusion tensor imaging (DTI) based graph theory analysis.Methods:The study was a cross-sectional study. Clinical and imaging data of 21 children with SCP (SCP group) and 32 healthy children (control group) who underwent cranial MRI at the Affiliated Hospital of Zunyi Medical University from August 2020 to April 2022 were analyzed retrospectively. 3D-T 1WI, DTI and Wechsler Intelligence Scale were assessed for all subjects. The Wechsler Intelligence Scale included the verbal comprehension index (VCI), the processing speed index (PSI), the work memory index (WMI), and the perceptual reasoning index (PRI), etc., and ultimately the full scale intelligence quotient (FSIQ) scores were obtained based on the indices of each subscale. Independent samples t-test was used to analyze the differences in the small world attributes [small-world index (σ), normalized shortest path length (λ), normalized clustering coefficients (γ)], global attributes [global efficiency (Eglob), local efficiency (Eloc), characteristic path length (Lp), clustering efficiency (Cp)] and node attributes [degree centrality(DC), nodal efficiency (Ne), betweeness centrality (Bc), nodal shortest path length (NLp), nodal clustering efficiency, nodal local efficiency] between two groups of children′s brain networks. Brain network indicators with statistically significant differences between the 2 groups were correlated with Wechsler Intelligence Scale scores using Spearman. Results:The FSIQ scores on the Wechsler Intelligence Scale and the VCI, WMI, PSI, and PRI were lower in the SCP group than in the control group, and the differences were all statistically significant (all P<0.05). Both groups of children′s brain networks had small world properties. Compared with the control group, Eglob decreased, Lp and λ increased in the SCP group (all P<0.05). Compared with the control group, DC and Ne in multiple brain regions decreased, NLp increased in the SCP group (all P<0.05, FDR corrected). Correlation analysis showed that DC in the right parsopercularis was positively correlated with FSIQ, VCI, WMI and PRI( r=0.53, 0.47, 0.47, 0.60, P=0.019, 0.045, 0.044, 0.020, respectively); NLp in the right parsopercularis was negatively correlated with PRI( r=-0.56, P=0.030); Ne in left paracentral, the right parsopercularis, right precentral, right postcentra were positively correlated with PRI( r=0.62, 0.56, 0.53, 0.54, P=0.015, 0.031, 0.044, 0.039, respectively); Ne in the right precentral was positively correlated with WMI ( r=0.48, P=0.039) in the SCP group. Conclusions:There are changes in the topological attributes of global and multiple regional brain networks in SCP. The changes in the attributes of nodes in the right parsopercularis, right precentral, right postcentral, and left paracentral could reflect cognitive dysfunction in children with SCP.

Objective:To investigate the effects and molecular mechanism of non-coding RNA-activated DNA damage(NORAD)induced autophagy on oxaliplatin resistance in adenocarcinoma of esophagogastric junction (AEG).Methods:Four pairs of surgical samples of AEG and para-carcinoma normal tissues from patients with advance AEG treated in Anyang Tumor Hospital from January to June 2023 were collected. The expression of NORAD in AEG and para-carcinoma tissues was analyzed by long non-coding RNA microarray chip. The primary tumor cell line of AEG (PDC) was derived from fresh AEG tissues. Oxaliplatin-resistant cell lines of PDC and AEG cell line OE19 (PDC-R and OE19-R) were established. NORAD expression knockdown PDC-R and OE19 cell lines (shNORAD PDC-R and shNORAD OE19-R) were prepared by transfection. The target of NORAD, the correlation and interaction between microRNA-433-3p (miR-433-3p) and NORAD were predicted using Starbase v3.0 and DIANA-lncBase v3.0. PDC, PDC-R, OE19 and OE19-R cells were co-transfected with miR-144-3p and wild-type NORAD (NORAD-WT) or mutant NORAD (NORAD-Mut) plasmid, respectively. Dual-luciferase reporter assay was used to verify the correlation between NORAD and miR-433-3p. The expression levels of NORAD and miR-433-3p in normal gastric mucosal cell line GES-1 and AEG cell lines PDC, PDC-R, shNORAD PDC-R, OE19, OE19-R and shNORAD OE19-R were detected by real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR). The expression of p62 protein and microtubule-associated protein 1 light chain 3B-Ⅱ (LC3B-Ⅱ) was determined by Western blotting. The half inhibitory concentration (IC 50) of PDC, PDC-R, shNORAD PDC-R, OE19, OE19-R and shNORAD OE19-R cells was measured by cell counting kit-8 (CCK-8) assay. Independent sample t-test was used for statistical analysis. Results:The results of microarray analysis showed that NORAD was significantly up-regulated in AEG compared with that in para-carcinoma tissues (fold change≥2.0, P<0.05). Bioinformatics studies found that miR-433-3p was the potential target of NORAD. The results of dual-luciferase reporter assay indicated that the relative luciferase activity of the NORAD-WT group was lower than that of NORAD-Mut group in PDC and PDC-R cells (0.441±0.104 vs. 0.928±0.204, 0.449±0.112 vs. 0.947±0.201), and the differences were statistically significant ( t=-14.74 and -14.94, both P<0.001). The results of dual-luciferase reporter assay of OE19 and OE19-R cell lines were the same as those of PDC cell lines. The results of qRT-PCR showed that the expression of NORAD in GES-1 cells (1.016±0.213) was lower than that of PDC cells (2.194±0.322) and PDC-R cells (4.040±0.336), and the differences were statistically significant ( t=-14.94 and -37.21, both P<0.001). Furthermore, the expression level of NORAD in PDC was also found to be lower than that in PDC-R cells, and the difference was statistically significant ( t=-19.43, P<0.001). Additionally, shNORAD PDC-R cells exhibited lower expression level of NORAD (0.290±0.165) compared with PDC-R cells, and the difference was statistically significant ( t=-49.05, P<0.001). The expression level of miR-433-3p in GES-1 cells (1.017±0.248) was higher than that in PDC cells (0.470±0.156) and PDC-R cells (0.203±0.045), and the differences were statistically significant ( t=9.15 and 15.85, both P<0.001). Moreover, the expression level of miR-433-3p was found to be higher in PDC cells compared with PDC-R cells, and the difference was statistically significant ( t=8.11, P<0.001). Additionally, the expression level of miR-433-3p in shNORAD PDC-R cells (0.699±0.256) was also higher than that in PDC-R cells ( t=9.37, P<0.001). The results of Western blotting showed that the expression of LC3B-Ⅱ in PDC-R was higher than that in PDC cells (0.426±0.060 vs. 0.212±0.041), the expression of LC3B-Ⅱ in shNORAD PDC-R cells (0.155±0.029) was lower than that in PDC cells, and the differences were statistically significant ( t=8.70 and -79.45, both P<0.001). However the expression of p62 protein in each cell line showed an opposite trend, with a lower relative expression in PDC-R than PDC (0.205±0.031 vs. 0.311±0.400), and the expression in shNORAD PDC-R (0.504±0.084) was higher than that in PDC, and the differences were statistically significant ( t=-31.19 and 62.80, both P<0.001). The expression patterns of NORAD, miR-433-3p, LC3B-Ⅱ and p62 proteins in OE19, OE19-R and shNORAD OE19-R cells were similar to those in PDC. The results of CCK-8 assessment of target cell viability showed that the IC 50 values of PDC, PDC-R and shNORAD PDC-R cell lines were 14.28, 22.27 and 2.51 μg/mL, respectively; and the IC 50 values of OE19, OE19-R and shNORAD PDC-R cell lines were 3.95, 8.12 and 1.89 μg/mL, respectively. Conclusions:NORAD is highly expressed in AEG tissues and cells. NORAD is overexpressed in oxaliplatin-resistant cell lines and increase the autophagy activity of cells. After NORAD is knockdown, autophagy activity is inhibited and the sensitivity of AEG cells to oxaliplatin is significantly enhanced.

Objective:
To understand the dilemma of different participants in school psychological crisis intervention, so as to provide guidance for the implementation of comprehensive psychological crisis intervention from multiple perspectives.
Methods:
From March 2022 to January 2023, a total of 10 psychological consultants, 10 counselors, 10 peer students, 10 parents and 10 clients were selected from a certain university using convenient sampling method was interviewed with semi structured interviews, and the transcribed data were analyzed according to grounded theory.
Results:
The predicaments of psychological crisis intervention mainly involved three core themes: early warning, ethical dilemma and negative emotion. Early warning approaches mainly included three core themes: school, social media and other institutions, and 50 participants reported mainly on peer students in schools(18 cases) and online media in social media(18 cases). Ethical dilemmas mainly focued on the conflict between confidentiality breaches and privacy protection. The negative emotions mainly include three core themes of anxiety, fear and powerlessness, which were characterized by dispersion. The optimization expectation of psychological crisis intervention mainly consisted of two core themes: professional expectation and collaborative expectation, both of which were the common expectation of the people involved.
Conclusion
School psychological crisis intervention should pay attention to the establishment of crisis early warning system and dialectic between confidentiality breaches and privacy protection. Schools should prevent the dispersion of negative emotions of participants, deepen professional construction and the coordination between home and school, and implement psychological crisis intervention from a comprehensive perspective.

The modernization and development of traditional Chinese medicine has led to higher standards for the quality of traditional Chinese medicine products. The extraction process is a crucial component of traditional Chinese medicine production, and it directly impacts the final quality of the product. However, the currently relied upon methods for quality assurance of the extraction process, such as simple wet chemical analysis, have several limitations, including time consumption and labor intensity, and do not offer precise control of the extraction process. As a result, there is significant value in incorporating near-infrared spectroscopy (NIRS) in the production process of traditional Chinese medicine to improve the quality control of the final products. In this study, we focused on the extraction process of Xiao'er Xiaoji Zhike oral liquid (XXZOL), using near-infrared spectra collected by both a Fourier transform near-infrared spectrometer and a portable near-infrared spectrometer. We used the concentration of synephrine, a quality control index component specified by the pharmacopoeia, to achieve rapid and accurate detection in the extraction process. Moreover, we developed a model transfer method to facilitate the transfer of models between the two types of near-infrared spectrometers (analytical grade and portable), thus resolving the low resolution, poor performance, and insufficient prediction accuracy issues of portable instruments. Our findings enable the rapid screening and quality analysis of XXZOL onsite, which is significant for quality monitoring during the traditional Chinese medicine production process.

Objective: To investigate hepatic perivascular epithelioid cell tumor (PEComa) diagnosis and treatment plan. Methods: 24 cases diagnosed with PEComa clinical manifestations, serum alpha fetoprotein (AFP), carcinoembryonic antigen (CEA), carbohydrate antigen 199 (CA199), imaging findings, surgical methods, postoperative hospital stay, pathological results and prognosis were analyzed retrospectively from September 2015 to September 2020. Results: Majority of patients were females (79.2%), aged 41.5±11.4 years. Tumors were predominantly located in the right liver (50.0%). 76.7% of the cases were mostly clinically asymptomatic. AFP, CEA and CA199 indices were all negative. CT mostly showed low density tumor in the plain scan phase, enhanced in the enhancement phase, and enhanced and weakened in portal venous and equilibrium phase (66.7%). MRI manifestations of most tumors were hypointense on T1WI and hyperintense on T2WI (72.7%). B-ultrasound mostly showed hyperechoic mass in the tumor area with punctate vascular shadow (52.9%). Postoperative hospital stay was 9.0±2.4 days for laparoscopic surgery patients (n=13), 13.4±6.3 days for traditional laparotomy (hereinafter referred to as laparotomy, n=10), and 3 days for 1 patient with microwave ablation. All postoperative pathological results were positive for HMB45 and Melan-A. Follow-up results: 21 cases survived normally, with no tumor recurrence in the recent physical examination; two cases had tumor recurrence and they died two and three years after surgery, and one case was lost to follow-up. Conclusion: Hepatic PEComa more commonly occurs in middle-aged women, with no specific features for tumor markers and clinical manifestations. Some imaging findings are specific, so its features can be combined as a basis for diagnosis. Postoperative pathological examination results can confirm the diagnosis. Therefore, surgery remains the initial treatment plan. Microwave ablation and laparoscopic surgery are recommended as the preferred option because of shorter hospital stays and less trauma than open surgery.

Objective:To analyze the incidence and epidemiological characteristics of traumatic spinal cord injury in China in 2018.Methods:Multi-stage stratified cluster sampling was used to randomly select hospitals capable of treating patients with spinal cord injury from 3 regions,9 provinces and 27 cities in China to retrospectively investigate eligible patients with traumatic spinal cord injury admitted in 2018. National and regional incidence rates were calculated. The data of cause of injury,injury level,severity of injury,segment and type of fracture,complications,death and other data were collected by medical record questionnaire,and analyzed according to geographical region,age and gender.Results:Medical records of 4,134 patients were included in this study,with a male-to-female ratio of 2.99∶1. The incidence of traumatic spinal cord injury in China in 2018 was 50.484 / 1 million (95% CI 50.122-50.846). The highest incidence in the Eastern region was 53.791 / 1 million (95% CI 53.217-54.365). In the whole country,the main causes of injury were high falls (29.58%),as well as in the Western region (40.68%),while the main causes of injury in the Eastern and Central regions were traffic injuries (31.22%,30.10%). The main injury level was cervical spinal cord in the whole country (64.49%),and the proportion of cervical spinal cord injury in the Central region was the highest (74.68%),and the proportion of lumbosacral spinal cord injury in the Western region was the highest (32.30%). The highest proportion of degree of injury was incomplete quadriplegia (55.20%),and the distribution pattern was the same in each region. A total of 65.87% of the patients were complicated with fracture or dislocation,77.95% in the Western region and only 54.77% in the Central region. In the whole country,the head was the main combined injury (37.87%),as well as in the Eastern and Central regions,while the proportion of chest combined injury in the Western region was the highest (38.57%). A total of 32.90% of the patients were complicated with respiratory complications. There were 23 patients (0.56%) died in hospital,of which 17(73.91%) died of respiratory dysfunction. Conclusions:The Eastern region of China has a high incidence of traumatic spinal cord injury. Other epidemiological features include high fall as the main cause of injury cervical spinal cord injury as the main injury level,incomplete quadriplegia as the main degree of injury,head as the main combined injury,and respiratory complications as the main complication.
