Objective: To evaluate the effects of Liu Zi Jue Qigong (LQG)-based breathing training on the curvature and range of motion (ROM) of the thoracic and lumbar spines in different positions. Methods: Forty-seven college students were selected as subjects and randomly divided into an observation group and a control group. In the observation group, 27 subjects received regular LQG-based breathing training for 12 weeks, while 20 subjects in the control group did not receive any intervention. The spine measuring instrument Spinal Mouse was adopted to detect the curvature and ROM of the thoracic and lumbar spines. Results: In the observation group, the changes in the curvatures of thoracic spine in the upright and forward-bending positions showed statistical significance after LQG exercise (P<0.05), while there was no notable difference in the control group. The comparison of ROM of the thoracic spine from the upright position to the forward-bending and load-bearing positions showed statistically significant difference in the observation group (P<0.05), while there was no significant difference in the control group. There was no significant difference in the lumbar curvature and ROM in the two groups after LQG exercise. Conclusion: LQG-based breathing training improves the curvature and ROM of the thoracic spine.

OBJECTIVE To analyze the changes of temporary abnormal intraepithelial papillary capillary loop(IPCL)in the surgical area of early glottic laryngeal cancer after CO2 laser resection.METHODS A retrospective study was conducted on early-stage glottic carcinoma patients who visited the Department of Otolaryngology,Head and Neck Surgery at the Second Affiliated Hospital from January 2017 to November 2023.Patients who underwent CO2 laser surgery accepted electronic laryngoscopy examination at 1 month,3 months,and 6 months postoperatively(including white light endoscopy and narrowband imaging endoscopy(NBI),and their medical history,treatment methods,laryngoscopy images,imaging data,and pathological results before and after treatment were systematically collected.The changes in laryngoscopy characteristics at different follow-up times after surgery were analyzed.RESULTS This study included 55 patients with non recurrent early glottic carcinoma who underwent CO2 laser surgery.At 1 month,3 months,and 6 months after surgery,there were significant differences in the proportion of patients with pseudomembrane coverage(72.73%vs.25.45%vs.7.27%),granulation formation(60.00%vs.34.55%vs.1.82%),and abnormal IPCL(23.64%vs.7.27%vs.0.00%)on the surface of the surgical area(P<0.001),and abnormal IPCL(mainly type Va and Vb)can be observed under NBI endoscopy from 1 month to 3 months after surgery.Within 6 months after surgery,the pseudomembrane detachment,granulation regression,scar formation,and abnormal IPCL in the surgical area disappeared.CONCLUSION Early glottic carcinoma patients may experience temporary abnormal IPCL within 3 months after receiving CO2 laser resection,but the abnormal IPCL could disappear within 6 months after surgery for some patients.Therefore,close observation is necessary within 6 months after surgery and there is no need for urgent biopsy.

Objective To investigate the mechanism behind the protective effects of gastrodin against microglia-mediated inflammatory responses following hypoxic-ischemic brain damage(HIBD)in neonatal mice.Methods Thirty-six 10-day-old C57BL/6J mice were randomized into sham-operated group,HIBD(induced by ligation of the left common carotid artery followed by hypoxia for 40 min)group,and HIBD with gastrodin treatment groups(n=12).In gastrodin treatment group,100 mg/kg gastrodin was injected intraperitoneally 1 h before and at 2 and 12 h after hypoxia.After the treatments,the expressions of CCR5,AKT,p-AKT,and TNF-α and the co-expression of IBA1 and CCR5 in the corpus callosum of the mice were detected with Western blotting and immunofluorescence double staining.In a BV2 microglial cell model of oxygen-glucose deprivation(OGD),the effects of pretreatment with gastrodin and Maraviroc(an CCR5 antagonist)on protein expressions of CCR5,AKT,p-AKT,TNF-α and IL-1β were evaluated using Western blotting and immunofluorescence double staining.Results The neonatal mice with HIBD showed significantly increased expressions of CCR5 and TNF-α with lowered p-AKT expression in the brain tissues,and GAS treatment obviously reversed these changes.HIBD also significantly increased the co-expression of IBA1 and CCR5 in the corpus callosum of the mice,which was obviously lowered by gastrodin treatment.In BV2 cells,OGD significantly increased the expressions of CCR5,TNF-α,and IL-1β and decreased the expression of p-AKT,and these changes were inhibited by treatment with gastrodin,Maraviroc or their combination;the inhibitory effect of the combined treatment did not differ significantly from that of gastrodin or Maraviroc alone.Conclusion Gastrodin can produce neuroprotective effects in neonatal mice with HIBD by inhibiting inflammatory cytokine production and activate AKT phosphorylation via inhibiting CCR5.

OBJECTIVE: To analyze the status and influencing factors of the health literacy(HL) of college students in a comprehensive university. METHODS: A total of 3 360 students from in a comprehensive university of Xinjiang Production and Construction Corps was selected using multi-stage stratified cluster random sampling method. The HL level of college students was investigated and evaluated with self-edited Xinjiang Construction Corps College Students Health Literacy Questionnaire. RESULTS: The HL level of college students was 17.1%. The HL level of medical students was higher than that of non-medical students(35.4% vs 10.0%, P<0.01). Logistic regression analysis results showed that among the medical students in grade three or four, those with medium and excellent academic achievement, and Han nationality had a positive effect on their HL level(P<0.01). Among the non-medical students, female and medicine related optional courses had a positive effect on their HL level(P<0.05). Students in the sophomore year had a negative effect on their HL level(P<0.05). CONCLUSION: There is a big difference in the level of HL between medical students and non-medical students. Medical college students and non-medical college students have different factors affecting HL, medical education is related to improving HL.

Objective To explore the effect of cranial electrotherapy stimulation (CES) on cognitive function for old patients with mild cognitive impairment.Methods A total of 40 old inpatients with mild cognitive impairment in 2018 and 2019 were randomly divided into control group (n = 20) and treatment group (n = 20). Both groups accepted routine medication (without cognitive drugs), and the treatment group accepted CES in addition, for eight weeks. They were assessed with modified Barthel Index (MBI) and Montreal Cognitive Assessment (MoCA) by two researchers single-blind before treatment, and four and eight weeks after treatment. The control group accepted free CES after trial.Results For MoCA score, the main effect was significant in time (F = 5.603, P = 0.007), not significant in group (F = 2.160, P = 0.150), and the effect of interaction was significant (F = 9.160, P < 0.001), which was more in the treatment group than in the control group. For MBI score, the main effects were not significant both in time (F = 0.322, P = 0.726) and in group (F = 0.009, P = 0.925), nor the effect of interaction (F = 0.322, P = 0.726). No adverse reactions occurred during CES intervention.Conclusion CES may be effective on mild cognitive impairment in old patients.
