Objective To study the differences of obstructive sleep apnea hypopnea syndrome (OSAHS)-related indexes between Uyghur and Han, and to provide evidence for the development of individualized treatment measures for different ethnic groups. Methods 224 Han OSAHS patients were collected from Guangdong Provincial Hospital of Chinese Medicine, and 178 Uygur OSAHS patients were collected from The First People’s Hospital of Kashi between January 2018 and December 2019. The collected data information included age, sex, nationality, body mass index (BMI), apnea hypopnea index (AHI), lowest oxygen saturation (LSaO2), OSAHS stage, mean corpuscular hemoglobin concentration (MCHC), triglyceride (TG), total cholesterol (TC), high density lipoprotein (HDL), low density lipoprotein (LDL), fasting blood glucose (FBG), and glycosylated hemoglobin (HbAlc). After using propensity matching scores to reduce confounding factors, differences in above indicators between different nationalities were compared. Results The mean values of MCHC, TC and HDL in Uygur OSAHS patients were lower than those in Han patients at the same stage, and the mean values of LSaO2 and LDL in mild and severe Uygur OSAHS patients were lower than those in Han patients at the same stage, with statistically significant differences (all P<0.05). There were no significant differences in AHI, TG, FBG or HbAlc between Uygur and Han patients with OSAHS. Conclusion There are significant differences in LSaO2, LDL, MCHC, TC and HDL between Uygur and Han Chinese patients with OSAHS.
Objective To investigate the effect of virtual reality (VR) sham feeding on gastrointestinal function in elderly patients with hip fracture. Methods Elderly patients with hip fracture admitted to Trauma Center, West China Hospital, Sichuan University between June and December 2024 who met the case selection criteria were selected. Patients who were willing to complete the postoperative VR operation were assigned to the experimental group (VR group), and the other patients were assigned to the control group by 1∶1 manual interval matching according to sex, age (±5 years), and body mass index (±2 kg/m2). The control group received fasting and nutrition management strategy during perioperative period of accelerated rehabilitation. In the VR group, VR sham feeding intervention was performed on the basis of the control group. The time of first postoperative exhaust and defecation, postoperative gastrointestinal symptoms, postoperative nutrition (hemoglobin, serum albumin) and inflammatory indicators (white blood cell count, erythrocyte sedimentation rate, C-reactive protein, interleukin-6), postoperative appetite and postoperative complications (bleeding, fever, delirium, aspiration, vertigo) were compared between the two groups. Results A total of 70 patients were enrolled, with 35 in each group. There were statistically significant differences (P<0.05) between the VR group and the control group in the time of postoperative first exhaust [(9.17±4.81) vs. (13.66±5.97) h], time of postoperative first defecation [(49.00±28.61) vs. (66.83±29.93) h], degree of abdominal distension 3 d after surgery (grade 0/1/2: 26/7/2 vs. 16/12/7 cases), appetite score 1 d after surgery (62.86±12.85 vs. 54.71±11.50), appetite score 3 d after surgery (76.29±9.95 vs. 62.43±8.86), albumin level 3 d after surgery [(33.18±3.41) vs. (31.40±3.07) g/L], and hospitalization days [(7.97±1.38) vs. (9.06±2.43) d], while there was no statistically significant difference in other indicators (P>0.05). Conclusions The incidence of postoperative gastrointestinal dysfunction is high in elderly patients with hip fracture. VR sham feeding can promote the early recovery of gastrointestinal function, alleviate postoperative abdominal distension, significantly improve postoperative appetite, and increase albumin level after surgery.
