Objective To develop a postoperative precision nursing program for children with obstructive sleep apnea-hypopnea syndrome(OSAHS),so as to provide references for the improvement of nursing quality for children with OSAHS.Methods Literature in precision nursing for children with OSAHS was systematically reviewed and summarised based on precision nursing theory and a postoperative precision nursing program was drafted.Using the Delphi's Method,two rounds of expert consultation were conducted and the postoperative precision nursing program for children with OSAHS was revised and finalised.Results The response rates of the two rounds of expert consultation were 100.00%with the expert authority coefficient of 0.875.The Kendall coefficient of concordance(W)of levels 1,2 and 3 indices in the second round of expert consultation were 0.289,0.203,0.187,respectively(all P<0.01).The importance score of each inclicator ranged from 4.50～4.94.The coefficient of variations for the three-level indices ranged from 0.05 to 0.21.The finalised program composed 8 level-1 indices(postoperative position assessment,intervention,prevention and care of bleeding,maintaining postoperative airway patency,postoperative nausea and vomiting care,postoperative pain assessment and care,dietary care,complication prevention and care,discharge guidance),16 level-2 indices,and 22 level-3 indices.Conclusion The postoperative precision nursing program for the children with OSAHS is scientific,innovative and applicable.It provides clinical references for nursing of the children with OSAHS.

Objective:To investigate the value of 99Tc m-hydrazinonicotinamide (HYNIC)-prostate specific membrane antigen(PSMA) SPECT/CT imaging in biochemical recurrence of prostate cancer (PCa). Methods:From January 2018 to March 2023, 112 patients with biochemical recurrence of PCa (age (72.6±6.1) years) who underwent 99Tc m-HYNIC-PSMA SPECT/CT imaging in Henan Provincial People′s Hospital were retrospectively analyzed. According to the level of prostate specific antigen (PSA), patients were divided into 0.2 μg/L2 μg/L group. According to the Gleason score, patients were divided into Gleason score≥8 group and Gleason score <8 group. The detection rate between groups was analyzed by χ2 test, and the difference of the PSA level between groups was compared by Mann-Whitney U test. Results:PSMA imaging was positive in 77 cases and negative in 35 cases, with the detection rate of 68.8%(77/112). The detection rates of local recurrence, lymph node metastasis, bone metastasis and lung metastasis were 8.9%(10/112), 43.8%(49/112), 28.6%(32/112) and 0.9%(1/112), respectively. The detection rates of 0.2 μg/L2 μg/L groups were 44.7%(21/47), 8/12 and 90.6%(48/53), respectively ( χ2=24.44, P<0.001). The detection rates of Gleason score ≥8 group and <8 group were 76.4%(55/72) and 55.0%(22/40) ( χ2=5.47, P=0.032); the PSA level between the two groups was statistically different (3.11(0.75, 5.91) and 0.84(0.44, 2.92) μg/L; z=-2.99, P=0.003). Of the patients with PSMA positive imaging, 84.4%(65/77) changed their treatment regimen and 15.6%(12/77) continued to observe or maintain the original treatment plan. Of the patients with PSMA negative imaging, 40.0%(14/35) changed the treatment plan, 51.4%(18/35) continued to observe or maintain the original treatment plan, and 8.6%(3/35) discontinued the original treatment because no tumor metastasis was found. Conclusion:99Tc m-HYNIC-PSMA SPECT/CT imaging can provide reference for the lesion detection, treatment decision-making and follow-up observation of biochemical recurrence of PCa.

Objective:To explore the risk factors of sarcopenia in liver cirrhosis and construct a diagnosis model for sarcopenia in cirrhosis.Methods:73 patients with liver cirrhosis hospitalized in Department of Gastroenterology of Shanxi Provincial People's Hospital between June 2021 and June 2022 were included. Common measurements in liver cirrhosis and abdominal CT scans of all patients were collected. The cross-sectional area of skeletal muscle at L3 level was calculated by sliceomatic and the skeletal muscle index (SMI) was subsequently obtained by height standardization. The patients were divided into sarcopenia group and non-sarcopenia group using Asian cut-off per European Working Group on Sarcopenia in Older People-2nd meeting (EWGSOP2) criteria. Risk factors related to sarcopenia in cirrhosis were analyzed and a subsequent diagnosis model was established.Results:among the cirrhotic patients included in the study, the prevalence of sarcopenia was 65.75% (48/73), 47.73% (21/44) in males and 93.10% (27/29) in females, respectively. There were significant differences in age, sex, BMI, liver function grade per Child Pugh classification, etiology, ferritin level, prothrombin time and hemoglobin level between sarcopenia and non-sarcopenia groups (P < 0.05). Age, liver function, sex and ferritin level were closely related to the occurrence of sarcopenia in cirrhosis. A diagnostic model was developed based on these 4 indexes and the area under curve reached up to 95.7%.Conclusion:≥ 60 years old, female, Child-Pugh C grade and ferritin < 29.60 μg/L are independent risk factors for sarcopenia in cirrhosis and the model with these indexes shows good diagnostic value for sarcopenia in cirrhosis.

Objective To explore the method of isolation, identification and in vitro differentiation of islet stem cells in neonatal rat. Methods The whole pancreata of neonatal rats were digested with collagenase, then,under the (condition) of pH 7.4～7.6,the digested tissue fragments were cultured with serum and serum-free RPMI 1640 (( bFGF), EGF, N2).The whole formation process of new islet cell-like cell masses was examined.The insulin (release) test was used to detect islet function. The expression of nestin was tested by immunocytochemistry. Results The nestin positive cells can be found within 36 h of culture of the digested pancreatic fragments.After addition of bFGF,ECF,N2,nestin positive cells proliferated fast and formed new islets-like cell masses after 18～24 d, and (insulin)ssion could be confirmed. Conclusions The nestin positive cells of pancreatic cells possess the character of islet stem cells, and can form islet like cell masses through culture in vitro.

Objective To explore the isolation, culture of nestin positive cells of the pancreas in newborn rats. Methods The whole pancreas of neonatal rats were digested with collagenase, followed by incubation under pH 7. 6 serum RPMI 1640 for 24 - 36 h and then under pH 7. 4 serum free RPMI 1640 (bFGF.EGF 20 ng/ml.1% N2) for 18-24 d. The expression of insulin.glucagon and nestin were detected by immunofluorescence technique. Nestin.CK19 were detected by RT-PCR. Resides Cells attached to the surface of plates after 24 h incubation under pH 7. 6 condition, and islet-like masses were obtained after 18 -24 d incubation. A monolayer of cells grew out after 24 h of passage of islet-like masses. Nestin positive cells was detected after 24 - 36 h incubation, with no expression of insulin and glucagon. Positive cells of insulin and glucagon were detected in islet-like masses after 24 h passage. Nestin positive cells were detected by RT-PCR in islet-like masses after 24 h passage, but no CK19. Conclusion Insulin and glucagon were expressed in islet-like masses after passage. Nestin positive cells in the pancreas of neonatal rats possessed character of islet stem cells.
