Objective:To translate Amyotrophic Lateral Sclerosis Impairment Multidomain Scale(AIMS)into Chinese,and to investi-gate its reliability and validity among Amyotrophic Lateral Sclerosis(ALS)patients.Methods:A total of 161 ALS patients who were registered in the registry system of Integrated Traditional Chinese and Western Medicine Treatment Center for Motor Neuron Disease in Hubei Provincial Hospital of Traditional Chinese Medicine from August 2023 to July 2024 were enrolled as subjects,and the Chinese version of AIMS was used for investigation after translation and revision.The Rasch model was used to assess the unidimensionality,in-ternal consistency,content validity,construct validity,and criterion-related validity of the questionnaire,and the classical test theory was used for item analysis,test-retest reliability analysis,and criterion-related validity analysis.Results:Unidimensionality testing showed that all three dimensions of AIMS have good unidimensionality.For all items except item 18,information-weighted fit statis-tic mean square(Infit MNSQ)and outlier-sensitive fit statistic mean square(Outfit MNSQ)ranged from 0.5 to 1.5,and point-measure correlation(PT-Measure)ranged from 0.63 to 0.87.The threshold between adjacent options of each item was>1.4 logit.Wright maps showed that item difficulties ranged from-2.24 to 2.08 logit,and the differential item functioning analysis showed that the absolute values of differences between patients across different char-acteristic subgroups were<1 logit.The overall scale and each di-mension had a reliability of>0.9,with an individual reliability of>0.7.The dimension of respiration had a separation index of 1.56,while the overall scale and the other dimensions had a separation in-dex of>2.The item analysis showed that the correlation coefficient between the items in each dimension and their respective dimen-sions ranged from 0.622 to 0.865(P<0.01).The overall scale and the dimensions of medulla oblongata,motor,and respiration had a test-retest reliability of 0.994,0.970,0.990,and 0.972,respectively(P<0.01).The criterion-related validity analysis showed that the correlation coefficients of total score and the score of each dimension between the Chinese version of AIMS and the revised version of AIMS were 0.863,0.829,0.876,and 0.755,respectively(P<0.01).Conclusion:The Chinese version of AIMS has a good degree of fit-ting and relatively high levels of reliability and validity,with moderate item difficulty,reasonable option settings,and high overall qual-ity,and it is suitable for the functional assessment of ALS patients in China.

Objective To investigate the effect of diosgenin on the proliferation and apoptosis of breast cancer cells and its potential molecular mechanism. Methods The breast cancer cell line MCF-7 was treated with low, medium, and high doses of diosgenin, and cell proliferation was detected through the MMT method. Flow cytometry was used to detect cell apoptosis. Nuclear-cytoplasmic-protein separation method was applied to detect the subcellular localization of death associated protein (DAXX). qRT-PCR and Western blot were used to detect the expressions of DAXX and c-Jun N-terminal kinase pathway (JNK)-related proteins. Results Diosgenin considerably inhibited the proliferation of MCF-7 cells and promoted cell apoptosis in a concentration-dependent manner. Diosgenin can promote the movement of DAXX from nucleus into the cytoplasm. Diosgenin upregulated the expression of cell surface death receptor (Fas), increased the phosphorylation levels of JNK and mitogen activated protein kinase (p38), and activated the JNK/p38 signaling pathway with concentration dependence. Conclusion Diosgenin inhibits the proliferation and promotes the apoptosis of the breast cancer cell line MCF-7, whose mechanism may be related to the regulation of DAXX subcellular localization and the activation of JNK/p38 signaling pathway.

Objective:To investigate the safety and efficacy of submucous radiofrequency ablation of the inferior turbinate, and to provide a clinical basis for the surgical treatment of allergic rhinitis in children. Methods:Patients with obstructive sleep apnea syndrome and allergic rhinitis who were admitted to the Department of Otolaryngology Head and Neck Surgery of Shanghai Children's Hospital from January 2021 to December 2023 and underwent bilateral submucous radiofrequency ablation of the inferior turbinate and radiofrequency ablation of the adenoid tonsil were included in the study. Observational and statistical indexes were used to evaluate the curative effect. Results:A total of 51 cases were included in this study, and 43 cases were followed up for half a year. Submucous radiofrequency ablation of the inferior turbinate plus radiofrequency ablation of the adenoid tonsil achieved a good effect （total effective rate 93%）, and there was a statistically significant difference in the preoperative and postoperative symptoms of the children（P<0.05）. There were no complications such as bleeding, Eustachian tube injury, nasal adhesion, or nasal dryness. Conclusion:Under the premise of strict control of surgical indications, children with allergic rhinitis can be treated surgically. Inferior turbinate submucous radiofrequency ablation is more minimally invasive, effective, and safe, and can be used in clinical practice.

Debates persist regarding the efficacy and safety of azvudine, particularly its real-world outcomes. This study involved patients aged ≥60 years who were admitted to 25 hospitals in mainland China with confirmed SARS-CoV-2 infection between December 1, 2022, and February 28, 2023. Efficacy outcomes were all-cause mortality during hospitalization, the proportion of patients discharged with recovery, time to nucleic acid-negative conversion (T _NANC), time to symptom improvement (T _SI), and time of hospital stay (T _HS). Safety was also assessed. Among the 5884 participants identified, 1999 received azvudine, and 1999 matched controls were included after exclusion and propensity score matching. Azvudine recipients exhibited lower all-cause mortality compared with controls in the overall population (13.3% vs. 17.1%, RR, 0.78; 95% CI, 0.67-0.90; P = 0.001) and in the severe subgroup (25.7% vs. 33.7%; RR, 0.76; 95% CI, 0.66-0.88; P < 0.001). A higher proportion of patients discharged with recovery, and a shorter T _NANC were associated with azvudine recipients, especially in the severe subgroup. The incidence of adverse events in azvudine recipients was comparable to that in the control group (2.3% vs. 1.7%, P = 0.170). In conclusion, azvudine showed efficacy and safety in older patients hospitalized with COVID-19 during the SARS-CoV-2 omicron wave in China.

Objective:To investigate the effects of sleep disorders (SD) on the radiation injury of hematopoietic stem cells (HSCs) in bone marrow (BM).Methods:Totolly 56 C57BL/6J male mice aged 6-8 weeks were enrolled in this study. They were subjected to whole body irradiation of 60Co γ-rays with doses of 5.0 and 7.5 Gy. A SD model was established using a SD device. According to the random number table method, the mice were divided into seven groups: the control group (Con group), the SD group, the mere radiation group (IR group), the group of post-irradiation SD (IR+ SD group), the group of post-irradiation SD treated with phosphate buffer solution (IR+ SD+ PBS group), the group of post-irradiation SD treated with GSK2795039 (IR+ SD+ GSK group), and the group of post-irradiation SD treated with N-acetylcysteine (IR+ SD+ NAC group), with in eight mice each group. The changes in the peripheral blood of the mice after 5.0 Gy irradiation were detected using the collected tail venous blood, and the survival rates of the mice after 7.5 Gy irradiation were observed. The changes in the density and count of bone marrow cells were observed using hematoxylin and eosin (HE) staining. The number of hematopoietic stem cells in bone marrow (LSK cells), as well as their apoptosis level and changes in cell cycle, were detected using flow cytometry. Furthermore, indicators of LSK, such as reactive oxygen species(ROS) and mitochondrial-derived reactive oxygen species (mtROS), were analyzed. Nicotinamide adenine dinucleotide phosphate (NADP+ /NADPH) and glutathione (GSSG/GSH) were detected using an enzyme microplate reader in order to observe the oxidative stress level of LSK. Furthermore, flow cytometry was employed to sort the LSK cells from the mice, and flow cytometry was used to detect the expression of NADPH oxidase 2(NOX2) and cysteinyl aspartate specific proteinnase-1(Caspase-1), and polymerase chain reaction (PCR) was used to detect the expression of inflammatory factors such as NOX1-4, interleukin 1β (IL-1β), interleukin 6 (IL-6), interleukin 18 (IL-18), and tumor necrosis factor α (TNF-α). Results:Compared to the IR group, the IR+ SD group exhibited significantly slower recovery of white blood cells (WBC) and platelets (PLT) ( t = 4.39, 6.37, P < 0.05), the bone marrow cell count decreasing from (2.14 ± 0.38) × 10 7 to (3.59 ± 0.29) × 10 7 ( t = 8.55, P < 0.05), significantly decreased proportion of G 0-phase LSK cells, significantly increased proportion of apoptotic cells ( t = 7.53, 8.21, P < 0.05), and significantly increased DCFH-DA, MitoSOX, and NADP+ /NADPH ( t = 22.99, 29.47, 3.77, P<0.05). In the case of IR, SD further promoted the activation of NOX2 and led to increases in the mRNA expression of downstream inflammatory factors such as IL-1β, IL-6, IL-18, and TNF-α ( t = 6.95, 6.01, 8.39, 4.91, 5.56, P < 0.05). Inhibition of NOX2-ROS could prevent the SD-induced aggravation of post-irradiation hematopoietic injury. This significantly reduced the apoptotic rate of LSK cells and the expression of inflammatory factors, ultimately accelerating the hematopoietic recovery of LSK cells ( t = 9.24, 3.92, P < 0.05). Conclusions:SD can aggravate the IR-induced injury of hematopoietic stem cells in bone marrow, primarily by activating the NOX2-ROS-Caspase-1 axis. This will increase the levels of intracellular inflammatory factors and ROS, promote cell apoptosis, and ultimately inhibit the hematopoietic recovery of bone marrow.

OBJECTIVE To determine the prevalence of frontal recess cells variations in patients with frontal sinus associated headache according to the International Frontal Sinus Anatomy Classification(IFAC).METHODS A retrospective study was conducted on the CT scans of sinuses in patients with frontal sinus associated headache.We reviewed 46 patients with frontal sinus-related headache who had clinical symptoms and were relieved after nasal endoscopic surgery.The development of frontal recess cells in the frontal recess drainage area was analyzed,and the variation of middle meatus and sinus involvement were analyzed in the same time.The Anatomical variations and imaging characteristics of frontal recess cells development in patients with frontal sinus associated headache were analyzed.RESULTS A total of 92 sinus CT profiles were analyzed in 46 patients.The most common cells were agger nasi cell(ANC)(100%,92/92),followed by supra bulla cell(SBC)(78.3%,72/92),supra agger cell(SAC)(67.4%,62/92),supra bulla frontal cell(SBFC)(27.2%,25/92),supra agger frontal cell(SAFC)(20.7%,19/92),frontal septal cell(FSC)(8.7%,8/92)and supraorbital ethmoid cell(SOEC)(0%,0/92).In the conventional frontal sinus drainage area,SAFC(P=0.0108),SAC(P=0.0104)and SAFC(P=0.0088)in the IFAC classification were significantly associated with the occurrence of frontal sinus associated headache.At the same time,the middle concha bullosa also showed a significant correlation with the occurrence of frontal sinus associated headache in the lower segment of the frontal recess drainage channel(P=0.0390).CONCLUSION In the frontal recess drainage channel,the abnormal development of SAC,SAFC,SBFC and the middle concha bullosa are significantly correlated with frontal sinus associated headache.

Deepening the teaching reform of medical education is the strategic initiatives to improve the quality of medical talents in the new period. At present, curriculum teaching reform and the certification work in medical colleges and universities is still in the initial exploration stage. Although some achievements have been made, there are still some prominent problems, such as insufficient teacher drive, inaccurate orientation for the curriculum, improper ways of teaching, lack of organizational and appraising system. Xuzhou Medical University takes the declaration and accreditation of educational reform courses as the forerunner, and takes many measures to stimulate teachers' endogenous motivation of educational reform, innovate the organizational system of educational reform courses evaluation, establish progressive evaluation and accreditation management, formulate evaluation standards of educational reform courses, and form a closed loop of multiple evaluation and feedback. It not only effectively improves the quality of teaching and further promote the curriculum reform process, but also provides reference for the development and promotion of curriculum teaching reform in other colleges and universities.

Objective:To explore the effect of combining functional electric stimulation (FES) with upper limb cycle training in rehabilitating upper limb motor function and ability in the activities of daily living after a stroke.Methods:Sixty hemiplegic stroke survivors were randomly divided into an experimental group and a control group. In addition to conventional rehabilitation therapy, the experimental group underwent 20 minutes of MOTOmed upper limb cycle training every day while receiving FES. The control group received only the 20 minutes of cycle training. Before and after 4 weeks, Brunnstrom staging was used to quantify hand and upper extremity functioning. The Fulg-Meyer assessment upper extremity scale (FMA-UE) and the modified Barthel index (MBI) were also used before the training and after 1, 2, 3 and 4 weeks of the treatments.Results:After 4 weeks of treatment, significant differences were observed in the average BS scores of both groups compared with before the intervention. The average hand and upper limb stages of the experimental group were significantly better than the control group′s averages. Significant improvement was also observed in the average FMA-UE and MBI scores of both groups after only one week, with significantly greater improvement in the experimental group.Conclusions:Supplementing upper limb cycle training with FES can significantly improve the upper limb motor function and ability in the activities of daily living of stroke survivors. It is more effective than the MOTOmed exercise alone.
