In this paper， by referring to ancient and modern literature， the textual research of Inulae Flos has been conducted to clarify the name， origin， production area， quality evaluation， harvesting， processing and others， so as to provide reference and basis for the development and utilization of famous classical formulas containing this herb. After textual research， it could be verified that the medicinal use of Inulae Flos was first recorded in Shennong Bencaojing of the Han dynasty. In successive dynasties， Xuanfuhua has been taken as the official name， and it also has other alternative names such as Jinfeicao， Daogeng and Jinqianhua. The period before the Song and Yuan dynasties， the main origin of Inulae Flos was the Asteraceae plant Inula japonica， and from the Ming and Qing dynasties to the present， I. japonica and I. britannica are the primary source. In addition to the dominant basal species， there are also regional species such as I. linariifolia， I. helianthus-aquatili， and I. hupehensis. The earliest recorded production areas in ancient times were Henan， Hubei and other places， and the literature records that it has been distributed throughout the country since modern times. The medicinal part is its flower， the harvesting and processing method recorded in the past dynasties is mainly harvested in the fifth and ninth lunar months， and dried in the sun， and the modern harvesting is mostly harvested in summer and autumn when the flowers bloom， in order to remove impurities， dry in the shade or dry in the sun. In addition， the roots， whole herbs and aerial parts are used as medicinal materials. In ancient times， there were no records about the quality of Inulae Flos， and in modern times， it is generally believed that the quality of complete flower structure， small receptacles， large blooms， yellow petals， long filaments， many fluffs， no fragments， and no branches is better. Ancient processing methods primarily involved cleaning， steaming， and sun-drying， supplemented by techniques such as boiling， roasting， burning， simmering， stir-frying， and honey-processing. Modern processing focuses mainly on cleaning the stems and leaves before use. Regarding the medicinal properties， ancient texts describe it as salty and sweet in taste， slightly warm in nature， and mildly toxic. Modern studies characterize it as bitter， pungent， and salty in taste， with a slightly warm nature. Its therapeutic effects remain consistent across eras， including descending Qi， resolving phlegm， promoting diuresis， and stopping vomiting. Based on the research results， it is recommended that when developing famous classical formulas containing Inulae Flos， either I. japonica or I. britannica should be used as the medicinal source. Processing methods should follow formula requirements， where no processing instructions are specified， the raw products may be used after cleaning.

Objective To investigate the relationship between internet addiction and SIOSS score,and to examine the mediating role of impulsivity and the moderating role of mental health level.Methods A total of 393 college students were tested with internet addiction scale,Barratt impulsiveness scale-version 11,SIOSS and symptom checklist 90 to establish a moderated mediation model.Results After adjusted for age,internet addiction tendency had a positive predictive effect on SIOSS score(β=0.523,P＜0.01).Impulsivity played a partial mediating role in the relationship between internet addiction and SIOSS score,with a mediating effect value of 0.087(45.72％).The first half of the mediating effect of internet addiction→impulsivity→SIOSS score was moderated by mental health level(β=-0.118,P＜0.001).The predictive effect of internet addiction on impulsivity was stronger in individuals with good mental health level(with the indirect effect value of 0.619 9+0.048 7)compared with the individuals with poor mental health level(with the indirect effect value of 0.439 5+0.048 5).Conclusion Internet addiction can increase SIOSS score by enhancing individual impulsivity,but this effect is more pronounced in individuals with good mental health and then affect SIOSS score.

Objective:To analyze the dual gain effect of hyperbaric oxygen combined with vestibular rehabilitation training on patients with tinnitus and dizziness.Methods:This study was a retrospective analysis,and 90 patients with tinnitus and dizziness who visited the outpatient department of our hospital from January 2022 to January 2025 were selected to carry out the study,and were divided into observation group and control group according to the treatment methods,with 45 cases in each group.The matched group patients were treated with conventional medication,while the observation group received hyperbaric oxygen combined with vestibular rehabilitation training on the basis of the matched group.The clinical efficacy of the two groups was compared,including the concentration of oxygenated hemoglobin in the cerebral cortex,vestibular function,severity of tinnitus,and severity of dizziness before and after treatment.Results:The total effective rate of the observation group was higher than the matched group(P＜0.05);Post-treatment,there was no significant change in the concentration of oxygenated hemoglobin in the parietal and occipital cortex between the two groups(P＞0.05).However,the concentration of oxygenated hemoglobin in the temporal lobe,dorsolateral prefrontal cortex,and frontal polar cortex increased,and the observation group was higher than the matched group(P＜0.05);Post-treatment,the values of hemiparesis,total area of center of gravity movement(CA),and total length of center of gravity movement(PL)in both groups decreased,and the observation group was lower than the matched group(P＜0.05);Post-treatment,the severity score of tinnitus in both groups decreased,and the observation group was lower than that in the matched group(P＜0.05);Post-treatment,the degree score of vertigo in both groups decreased,and the observation group was lower than that in the matched group(P＜0.05).Conclusion:Hyperbaric oxygen combined with vestibular rehabilitation training has a significant dual gain effect on patients with tinnitus and dizziness,which can improve clinical efficacy,promote cortical neural activity,improve vestibular function,and thereby alleviate the severity of tinnitus and dizziness.

This article reported a case of autosomal dominant intellectual developmental disorder type 22 caused by a heterozygous mutation in the ZBTB18 gene. At 24 +4 weeks of gestation, prenatal ultrasound indicated a short outer diameter of the fetal corpus callosum and bilateral ventricular dilatation. Whole-genome copy number variation analysis of the fetus showed no abnormalities. Whole exome sequencing (WES) and Sanger sequencing validation of the family revealed the fetus carried a c.1374_1383del(p.S459*) heterozygous mutation in the ZBTB18 gene (NM_205768.3), which was neither phenotypically present nor genotypically detected in the parents, suggesting a de novo mutation. Based on the clinical manifestations, the fetus was diagnosed with autosomal dominant intellectual developmental disorder type 22. After genetic counseling, the pregnant woman opted for termination of the pregnancy. This case highlights the correlation between prenatal ultrasonic detection of callosal dysgenesis and lateral ventricular enlargement and intellectual developmental disorders caused by gene mutations. Furthermore, it expands the mutation spectrum of the ZBTB18 gene, thereby facilitating prenatal diagnosis and genetic counseling.

Objective:To investigate the influence and mechanism of bone marrow mesenchymal stem cells (BMSCs) overexpressing growth arrest specific 6, i.e. GAS6/BMSCs on full-thickness skin defect wounds in diabetic mice.Methods:This study was an experimental study. Twelve 8-week-old male C57BL/6J mice were divided into a control wound group with only full-thickness skin defects and a diabetic wound group with diabetic full-thickness skin defects according to the random number table method, with 6 mice in each group. The wound healing rates were calculated at 3, 7, 14, and 21 days after injury. At 21 days after injury, wound tissue specimens were collected for hematoxylin-eosin staining to observe the histopathological conditions; Masson staining was performed to detect collagen deposition; immunohistochemical staining was performed to detect the number of proliferating cell nuclear antigen (PCNA)-positive cells and CD31-positive cells, representing cell proliferation and capillary density, respectively; immunofluorescence staining was performed to detect the number of F4/80 and myeloperoxidase (MPO) double-positive cells, indicating efferocytosis. Two 4-week-old male C57BL/6J mice were used to extract BMSCs, and GAS6/BMSCs were constructed through adenovirus transfection and successfully identified. Eighteen 8-week-old male C57BL/6J mice were used to create diabetic full-thickness skin defect wound models and divided into phosphate buffered solution (PBS) group, BMSC group, and GAS6/BMSC group (with 6 mice in each group) according to the random number table method. Immediately after injury, PBS, BMSC single-cell suspension, and GAS6/BMSC single-cell suspension were injected locally into the wounds of the three groups of mice, respectively. The wound healing rates were calculated, and the cell proliferation, capillary density, and efferocytosis were detected at the same time points as the previous experiments.Results:At 3, 7, 14, and 21 days after injury, the wound healing rates of mice in diabetic wound group were significantly lower than those in control wound group (with t values of 7.99, 8.62, 9.80, and 5.85, respectively, P<0.05). Compared with those in control wound group, the wound tissue of mice in diabetic wound group showed the infiltration of a large number of inflammatory cells and reduced collagen deposition at 21 days after injury. At 21 days after injury, the number of PCNA-positive cells and CD31-positive cells in the wound tissue of mice in diabetic wound group were significantly less than that in control wound group (with t values of 6.61 and 5.38, respectively, P<0.05). At 21 days after injury, the number of F4/80 and MPO double-positive cells in the wound tissue of mice in diabetic wound group was 3.3±0.8, which was significantly less than 12.7±1.8 in control wound group ( t=11.00, P<0.05). At 14 and 21 days after injury, the wound healing rates of mice in BMSC group were significantly higher than those in PBS group ( P<0.05); at 3, 7, 14, and 21 days after injury, the wound healing rates of mice in GAS6/BMSC group were significantly higher than those in BMSC group ( P<0.05). At 21 days after injury, the number of PCNA-positive cells in the wound tissue of mice in BMSC group was significantly higher than that in PBS group ( P<0.05), and the number of PCNA-positive cells and CD31-positive cells in the wound tissue of mice in GAS6/BMSC group were significantly higher than that in BMSC group ( P<0.05). At 21 days after injury, the number of F4/80 and MPO double-positive cells in the wound tissue of mice in BMSC group was 4.2±1.2, which was similar to 3.5±1.1 in PBS group ( P>0.05); the number of F4/80 and MPO double-positive cells in the wound tissue of mice in GAS6/BMSC group was 8.2±1.2, which was significantly more than that in BMSC group ( P<0.05). Conclusions:Dysfunctional efferocytosis of macrophage exists in the full-thickness skin defect wounds of diabetic mice, while GAS6/BMSC can promote wound healing by restoring the efferocytosis of macrophages.
