Objective:To explore application effect of early respiratory training schemes based on 4E mode (Engage, Educate, Execute, Evaluate) in children with bronchiolitis obliterans (BO) and provide evidence for the clinical implementation of early respiratory rehabilitation in children with BO.Methods:This was a quasi-experimental study. The children with BO who were admitted to 2 wards of the Department of Respiratory Medicine of Hunan Children's Hospital from January 1 to December 31, 2021 were selected as the research objects. They were randomly divided into the control group and the experimental group, with 23 cases in each group. The control group received routine treatment, nursing and rehabilitation guidance. The experimental group established a multidisciplinary team based on the control group, and used the early respiratory training program based on the 4E model to implement intervention. The clinical symptom severity scale was used to evaluate the improvement of the clinical symptoms of the children within 24 hours of being diagnosed as BO, the day of discharge, and 1 and 3 months after discharge for re-examination, and the hospitalization time of the children and the incidence of adverse events related to respiratory training were counted by using medical records and questionnaires.Results:The clinical symptom severity scores of the experimental group within 24 hours of admission diagnosis and the day of discharge were (20.00 ± 2.51) and (11.30 ± 2.46)points respectively, while those of the control group were (20.57 ± 2.21) and (11.70 ± 2.42) points respectively, with no statistically significant difference ( t=0.81, 0.54, both P>0.05). The clinical symptom severity scores of the experimental group were(10.52 ± 2.31) and (8.55 ± 1.06) points, lower than (12.32 ± 1.39) and (12.45 ± 2.19) points of the control group when they returned to the hospital for re-examination 1 and 3 months after discharge, with a statistically significant difference ( t=3.14, 7.25, both P<0.05). The experimental group was hospitalized for (11.78 ± 1.17) days, which was showter than (13.74 ± 1.63) days in the control group, with a statistically significant difference ( t=4.68, P<0.05). No respiratory training-related adverse events occurred in both groups of children during hospitalization. During home respiratory training after discharge, 1 and 2 respiratory training-related adverse events occurred in the experimental group 1 and 3 months after discharge, respectively, compared with 6 and 9 in the control group. The difference was statistically significant ( χ2=4.64, 5.94, both P<0.05). Conclusions:Early respiratory training solutions based on the 4E mode can improve the clinical symptoms of BO children, shorten the hospitalization time, reduce the number of adverse events related to respiratory training, and promote the recovery of children.

OBJECTIVE To investigate the effects of esketamine combined with dexmedetomidine used for drug-induced sleep endoscopy in patients with obstructive sleep apnea syndrome. METHODS Totally 60 patients with obstructive sleep apnea syndrome were randomly divided into control group and observation group ，with 30 cases in each group. Anesthesia induction scheme of control group included loading dose of dexmedetomidine 1 μg/kg，pumped for 10 min，maintained at 1 μg（/ kg·h），and intravenous administration of propofol at a constant rate of 3 mg（/ kg·h）until the patient snored. That of observation group included same administration route and dose of dexmedetomidine as control group ，intravenous administration of esketamine 1 mg/kg at a constant rate of 0.5 mg/（kg·h）until the patient snored. Sleep endoscopy was performed when the bispectral index （BIS）was lower than 75 and the alert /sedation（OAA/S）score was higher than 1. The vital signs ，BIS and OAA/S scores of patients in awake state （T0），10 min load dose of dexmedetomidine infusion （T1），at the time of examination （T2）and at the end of examination （T3） were recorded ，as well as the patient ’s medication （including the one-time success rate of examination ，the number of additional drugs due to physical movement during examination ），and the occurrence of adverse events after medication. RESULTS In the comparison between groups ，the pulse oxygen saturation （SpO2）and BIS of patients in the observation group were significantly higher than those in the control group at T1，T2 and T3；the heart rates and mean arterial pressures （MAP）at T2 and T3 were significantly lower than those in the control group ；and the OAA/S score at T1 and T2 were significantly higher than those in the control group （P＜0.05）. Comparison within the group ，the heart rates at T1，T2 and T3 in the observation group were significantly lower than those at T0，and the MAP at T2 and T3 were significantly lower than that at T1（P＜0.05）；in control group ，compared with T0，SpO2 decreased significantly at T1，T2 and T3，heart rate decreased significantly at T1，and MAP increased significantly at T2（P＜0.05）. Sixty patients successfully completed drug-induced sleep endoscopy after medication. The one-time success rate of examination in the observation group was significantly higher （No.191460443） than control group （P＜0.05），and the number of additional drugs due to physical movement during examination was significantly less than control group （P＜0.05）. There was no significant difference in the incidence of adverse events between 2 groups（P＞0.05）. CONCLUSIONS Esketamine combined with dexmedetomidine has less respiratory inhibition and less effect on hypoxia hemodynamics in patients with obstructive sleep apnea syndrome. It has less intervention times in the process of sleep endoscopy ，and has more advantages than propofol.

Objective:To establish an evaluation index system of hospital culture construction led by Party building in public hospitals, and to explore the relationships among Party building, hospital culture and patient satisfaction, and explain the mediating effect of hospital culture between Party building and patient satisfaction.Methods:Literature review and two rounds of Delphi method were used to create an evaluation index system of hospital culture construction led by Party building in public hospitals. On such basis, a questionnaire was designed and 429 staff from 33 public hospitals in Shanghai were surveyed through April and June 2021. Cronbach α coefficient method and exploratory factor analysis were used to test the reliability and validity of the indexes, and the regression analysis method was used to verify the mediating effects. Results:Following two rounds of Delphi survey run by 14 experts, a performance evaluation index system for the hospital culture construction was constructed, comprising 5 level-1, 13 level-2 and 29 level-3 indexes. The Cronbach α coefficients of overall indexes and 5 level-1 indexes fell in the range of 0.860-0.901( P<0.01), and the retest reliability of overall index and 5 level-1 indexes fell between 0.91-0.93( P<0.01). Based on the exploratory factor analysis, all of the characteristic roots of the factors generated by orthogonal rotation were>1, and the total variance explained contribution rate was 56.84%, proving the good validity of the indexes. The effect of Party building on patient satisfaction was significant( β1=0.139, P<0.01), and that on hospital culture effect significant as well( β2=0.168, P<0.01), while that on patient satisfaction was also significant( β3=0.115, δ=0.448, P<0.01)with hospital culture effect introduced as the mediating effect. Conclusions:The evaluation index system of hospital culture construction led by Party building proves highly scientific and effective, and hospital culture plays to some extent a mediating role between Party building and patient satisfaction. This proves that Party building presents a significant transmission effect on patient satisfaction through hospital culture building. The study provides a reference for strengthening Party building and hospital culture construction and improving patient satisfaction in public hospitals.

Objective: To investigate the frequency of KRAS mutation in mucinous epithelial lesions of the endometrium, and analyze the correlation between KRAS mutation and the clinicopathologic features. Methods: The cohort included forty-three cases of mucinous epithelial lesions of the endometrium selected from July 2015 to October 2017 from Beijing Obstetrics and Gynecology Hospital, and 22 control cases. Genomic DNA was extracted from formalin-fixed paraffin-embedded tissue sections. Polymerase chain reaction amplification for KRAS exons 2 and 3 was performed, followed by sequencing using capillary electrophoresis. The Fisher exact test was used to compare the prevalence of KRAS mutation among the different groups. Results: The patients′age ranged from 33 to 77 years [mean (55.12±9.34) years, median 55 years]. None of the eight cases of endometrial hyperplasia with mucinous differentiation without atypia showed KRAS mutation. The frequency of KRAS mutations was 1/10 in endometrial atypical hyperplasia, 1/12 in endometrioid carcinoma, 4/11 in endometrial atypical hyperplasia with mucinous differentiation (EAHMD), 6/15 in endometrioid carcinoma with mucinous differentiation (ECMD) and 8/9 in mucinous carcinoma (MC), respectively. The differences were statistically significant between MC versus EC (P<0.01) and MC versus ECMD (P<0.05). Conclusion The high frequency of KRAS mutation in EAHMD, ECMD and MC indicates that KRAS mutational activation is implicated in the pathogenesis of endometrial mucinous carcinoma.

OBJECTIVETo explore the effect of transcutaneous electrical acupoint stimulation (TEAS) on postoperative analgesia of ureteroscopic holmium laser lithotripsy.

METHODSOne hundred and twenty adult patients, American Association of Anesthesiologists (ASA) Class Ⅰ or Ⅱ, scheduled to ureteroscopic holmium laser lithotripsy, were randomly assigned into an observation group and a control group, 60 cases in each one. The patients in the observation group were treated with TEAS for postoperative analgesia. TEAS was implemented at bilateral Shenshu (BL 23) and Yinlingquan (SP 9) at the time of back ward and postoperative 4 h, 8 h, 12 h. TEAS at 7:00, 11:00 and 15:00 at the above acupoints were used on the second and third days; while placebo (twice a day, 100 mg a time) was used. Tramadol hydrochloride tablets for postoperative analgesia were applied in the contnol group, twice a day, 100 mg a time, and electrode sheets without stimulation were put on Shenshu (BL 23) and Yinlingquan (SP 9). When analgesia was insufficient with the score of visual analogue scale (VAS)≥3, the patients were treated with tramadol tablets for remedy analgesia. The VAS score, the concentrations of serotonin (5-HT) and substance P (SP) in 3 mL venous blood at the time of back ward (T), postoperative 4 h (T), 12 h (T), 24 h (T), and 48 h (T) were detected respectively. The total amount of medication for remedy analgesia and the incidence of adverse reactions, such as nausea and vomiting within postoperative 48 h were compared between the two groups.

RESULTSThe VAS scores at T through T were lower than those at T in the two groups (all <0.05). Compared with the control group, the VAS scores at T through T in the observation group were lower (all <0.05). The total dose of remedy analgesic medicine within 48 h after operation in the observation group was lower than that in the control group (<0.05). Compared with the control group, the concentrations of 5-HT at T, T, T and SP at T through T were lower (all <0.05). The numbers of constipation, nausea and vomiting in the observation group were less than those in the control group (both <0.05).

CONCLUSIONTEAS can relieve the pain and reduce the total amount of analgesic medicine, the levels of substance causing pain and the incidence of adverse reactions after ureteroscopic holmium laser lithotripsy.

Background and purpose:Increasing thyroid cancer (TC) incidence has caused wide public concern. It is typically interpreted as an increase in the true occurrence of TC but may also relfect changing life style or aging of population or increased diagnostic scrutiny. This study describes the temporal trend for incidence of TC and survival rate of patients by summarizing the 41 years TC incidences and follow-up data in Xuhui District, Shanghai.. Methods:Annual TC incidence data of Xuhui District from 1973 to 2013 were provided by Shanghai Cancer Registry System. The calculation of age-standardized incidence rates (ASIR) was based on the population of the year 1973. Temporal trends in TC incidence were analyzed based on the natural spline regression model. Annual percentage change (APC) was estimated by Jointpoint software from US National Cancer Institute, as well as survival rates were estimated using Kaplan-Meier method by Stata software.Results:During the period from 1973 to 2013, papillary cancer was the dominant type with proportion 69.8%. The ASIRs for female TC were 2.51-2.70 times as high as those for male TC. The average age of TC incidence for male was 50.04±14.71 while for female was 48.57±13.65. When aging factors were removed, incidence rate of TC was on the rise since 1981 with the APC of 8.46% (95%CI: 5.9%-11.1%), and on a rapid growth from 2004 to 2013 with the APC of 20.30% (95%CI: 9.8%-31.7%). The study showed that the 5-year TC survival rate was 95.21%, and the 10-year TC survival rate was 89.09%. In addition, survival rate of female was higher than that of male (χ2=15.43,P=0.000 1).Conclusion:The rising trend of TC in Xuhui District is similar to those in Shanghai and some developed countries. Although the mortality rate of TC is low, it has a rapid increase in incidence. Studies on factors associated with TC will help to clarify the epidemiological features about TC and promote more eff-cient prevention and control strategies.

Objective:To detect the expression of microRNA-218 (miR-218) in human acute lymphocyte leukemia (ALL) T lymphocytes ( CCRF-CEM) ,explore its effects on the biological features of CCRF-CEM cells and the expression of its target gene c-kit, so as to provide new insights for leukemia treatment.Methods: Using the quantitative real-time polymerase chain reaction ( qRT-PCR) ,we detected the expression of miR-218 in the normal peripheral blood T lymphocytes and CCRF-CEM cells.Forty-eight hours after the miR-218 mimic was transfected into the CCRF-CEM cells,the expression of miR-218 in the CCRF-CEM cells was detected by qRT-PCR.The effect of miR-218 on the CCRF-CEM cell viability was detected using MTT.The effect of miR-218 on the proliferation and apoptosis of CCRF-CEM cell was analyzed using flow cytometry.c-kit gene was identified to be a target gene of miR-218 by luciferase reporter enzyme system,and the effect of miR-218 on the expression of KIT protein in cells were determined using Western blot.Results:As shown by qRT-PCR,compared with that in the normal peripheral blood T lymphocytes,the expressions of miR-218 in ALL T lymphocytes cell lines were significantly decreased ( P<0.01 ) .Compared with the control group, the expression of miR-218 increase significantly in CCRF-CEM cells transfected with miR-218 mimic for 48 hours ( P<0.01).MTT showed that the cell viability decreased significantly after the over-expression of miR-218 in the CCRF-CEM cells ( P<0.05 ) .Flow cytometry showed that the S-phase fraction significantly declined after the over-expression of miR-218 ( P<0.01 ) , and meanwhile the apoptosis of cells also significantly increased (P<0.01).Luciferase reporter gene assay showed that,compared with the control group,the relative luciferase activity significantly declined in the miR-218 mimic transfection group (P<0.01).Compared with the control group,the expression of KIT protein in the CCRF-CEM cells transfected with miR-218 mimic for 48 hours significantly decreased ( P<0.01).Conclusion:The expression of miR-218 decreases in ALL T lymphocytes cell lines.MiR-218 can negatively regulate the expression of KIT protein,inhibit the proliferation and increase the apoptosis of CCRF-CEM cells.Treatment based on the enhanced expression of miR-218 may be a promising strategy for leukemia.
