Objective·To investigate the anesthetic effect of PetCO2 monitoring nasopharyngeal airway on preventing hypoxia in patients with obstructive sleep apnea syndrome(OSAS)during magnifying endoscopy.Methods·Eighty OSAS patients who underwent magnifying endoscopy anesthesia in Xuchang Central Hospital of Henan Province from February to June 2023 were randomly divided into PetCO2 monitoring nasopharyngeal airway group(group T)and traditional nasopharyngeal airway group(group B),with 40 cases in each group.General information,perioperative data and total anesthetic dosage of the two groups of patients were collected and compared.The systolic blood pressure(SBP),diastolic blood pressure(DBP),heart rate(HR)and pulse oxygen saturation(SpO2)of the two groups of patients before anesthesia(T0),at the time of entering the endoscopy(T1),3 min after entering the endoscopy(T2),10 min after entering the endoscopy(T3)and at the end of endoscopy(T4)were observed and recorded,respectively.The incidence of body movement and hypoxemia,and the effects of preventing hypoxia(including mask ventilation,jaw-lift support and chest compressions to assist breath)of the two groups of patients were recorded.Results·There were no significant differences in general information,perioperative data and total anesthetic dosage between the two groups.At T1 and T2,SpO2 in group T was higher than that in group B(T1:P=0.041,T2:P=0.012),and there was no statistically significant difference in SBP,DBP and HR between the groups;at other time points,there was no statistically significant difference in the four indicators between the two groups.Compared with group B,the incidences of body movement,hypoxemia,mask ventilation,jaw-lift support and chest compressions to assist breath in group T were all decreased(all P=0.000).Conclusion·PetCO2 monitoring nasopharyngeal airway can reduce the incidence of hypoxia during magnifying endoscopy in patients with OSAS,with minimal adverse events.Also,it can detect the status of lung ventilation in time,guide clinical intervention,reduce complications and improve the safety of magnifying endoscopy anesthesia.

Objective To explore a method of nursing post evaluation in the physical examination center and provide basis for performance appraisal and compensation management. Methods A total of 13 nursing posts were evaluated by 23 staff members in physical examination center and 7 evaluators from other departments of the hospital between June and August 2015 using Hay′s guide chart-profile method. Results The highest score of 13 nursing posts was 805. 4 and the lowest score was 80. 1. The average score of nursing posts in the morning and afternoon were (230. 9 ± 65. 6) and (190. 6 ± 85. 1). There was no significant difference between groups (t =0. 929,P =0. 375). Conclusions Hay′s guide chart-profile method can be used to compare the relative value of different nursing posts in physical examination center and can provide basis for performance appraisal and compensation management.

Objective To investigate the health status of nurses in hospital , and to provide the basis for the implementation of health management and health promotion in nurses .Methods We analyzed the physical examination information of 2 397 nurses in level three class A hospital from 2013 to 2015 , and compared with disease detection situation in different age groups , and analyzed disease detection rate among different age groups.Results The top three health hazards of nurses were breast disease (56.9%), thyroid disease (48.1%) and abnormal pelvic B ultrasound ( 33.7%).Pathoglycemia, dyslipidemia, hepatic adipose infiltration detection rate had increased in recent three years , and there were statistically significant differences (χ2 =13.83,4.90,18.18;P<0.05), and all the detection rates of the disease presented the increasing trend with age growing .Conclusions The health status of nursing staff is not optimistic .Managers of hospital should actively carry out health management and health promotion for nurses .

Background: Chronic exposure to elevated levels of saturated fatty acids results in pancreatic β-cell senescence. However, targets and effective agents for preventing stearic acid-induced β-cell senescence are still lacking. Although melatonin administration can protect β-cells against lipotoxicity through anti-senescence processes, the precise underlying mechanisms still need to be explored. Therefore, we investigated the anti-senescence effect of melatonin on stearic acid-treated mouse β-cells and elucidated the possible role of microRNAs in this process. Methods: β-Cell senescence was identified by measuring the expression of senescence-related genes and senescence-associated β-galactosidase staining. Gain- and loss-of-function approaches were used to investigate the involvement of microRNAs in stearic acid-evoked β-cell senescence and dysfunction. Bioinformatics analyses and luciferase reporter activity assays were applied to predict the direct targets of microRNAs. Results: Long-term exposure to a high concentration of stearic acid-induced senescence and upregulated miR-146a-5p and miR- 8114 expression in both mouse islets and β-TC6 cell lines. Melatonin effectively suppressed this process and reduced the levels of these two miRNAs. A remarkable reversibility of stearic acid-induced β-cell senescence and dysfunction was observed after silencing miR-146a-5p and miR-8114. Moreover, V-maf musculoaponeurotic fibrosarcoma oncogene homolog A (Mafa) was verified as a direct target of miR-146a-5p and miR-8114. Melatonin also significantly ameliorated senescence and dysfunction in miR-146a-5pand miR-8114-transfected β-cells. Conclusion These data demonstrate that melatonin protects against stearic acid-induced β-cell senescence by inhibiting miR-146a- 5p and miR-8114 and upregulating Mafa expression. This not only provides novel targets for preventing stearic acid-induced β-cell dysfunction, but also points to melatonin as a promising drug to combat type 2 diabetes progression.

Objective To explore the effect of Jinhoujian spray on postoperative sore throat (POST) after implantation of streamlined liner of pharyngeal airway (SLIPA) in general anesthesia. Methods A total of 100 patients undergoing lower limb fracture surgery with laryngeal mask general anesthesia in Xuchang Central Hospital, Henan University of Science and Technology from January 1, 2024, to May 31, 2024 were randomly divided into Jinhoujian spray group (Jinhoujian group) and lidocaine aerosol group (lidocaine group), with 50 cases in each group. Jinhoujian spray and lidocaine aerosol were applied to both sides of the laryngeal mask sealing cover, and after intravenous induction of general anesthesia, the same anesthesiologist inserted the laryngeal mask using a blind probing standard method. Mean arterial pressure (MAP) and heart rate (HR) were compared between the two groups at different time points: before laryngeal mask insertion (T₀), immediately after insertion (T₁), 3 minutes after insertion (T₂), 5 minutes after insertion (T₃), 10 minutes after insertion (T₄), immediately after mask removal (T₅), 3 minutes after removal (T₆), and 5 minutes after removal (T₇). The incidences of stress responses (coughing, airway spasm, agitation, nausea and vomiting) and adverse reactions (tongue numbness, arytenoid joint dislocation, dysphagia, restricted protective reflexes, and pharyngeal arch injury) after laryngeal mask removal were compared between the two groups. The numeric rating scale (NRS) at 0.5 h, and NRS, hoarseness, and extubation reaction at 24 h after mask removal were compared between the two groups. Results There were no statistically significant differences in baseline data and MAP and HR values at each time point (T_0-7) between the two groups. Compared with the lidocaine group, the patients in Jinhoujian group had a lower incidence of nausea and vomiting after laryngeal mask removal (P＝0.021). There was no statistically significant difference in the numeric rating scale (NRS) score 0.5 h after laryngeal mask removal between the two groups. Compared to the lidocaine group, the patients in Jinhoujian group had significantly lower scores of NRS (P＝0.027), Prince-Henry (P＝0.002), and oral mucositis (P＝0.026) 24 h after laryngeal mask removal . Conclusions Jinhoujian spray can effectively reduce incidence of postoperative nausea and vomiting, alleviate POST and oral mucositis 24 h after laryngeal mask removal, improving patient comfort after lower limb fracture surgery.
