Objective To explore the application effects of 3M circular opening self-adhesive wound dressing on changing tracheostoma dressing.Methods A total of 56 tracheotomized patients from January to December 2014 were randomly admited to either observation group or control group.Different tracheostoma dressings were chosen by the two groups,the patients of observation group adopted 3M circular opening selfadhesive wound dressing and the patients of control group received sterile gauze.Skin situation after tracheotomy,incision infection,dressing frequency,cost and patient's satisfaction were evaluated.Results Three cases suffered from adverse skin reaction in observation group and 13 cases in the control group,with a statistically significant difference(x2 =8.750,P ＜ 0.05);the frequency of changing dressing was no significant difference between two groups (P ＞ 0.05),the observation group was once a day,while the control group was three times a day;the hospitalization costs were (59 242.16 ± 3 276) (￥) in the observation group,while it was (50 369.22 ±2 892) (￥) in the control group (t =6.420,P ＜ 0.05);patient's satisfaction in observation group was 96.43％,but 71.43％ in the control group (x2 =4.766,P ＜ 0.05).Conclusions 3M circular opening self-adhesive wound dressing for neurosurgery patients after tracheotomy can reduce complications,the rate of incisional infection,the hospitalization costs and improve patients' satisfaction and comfort,which also reduce the working load of clinical nurse.

Objective To explore the effect of interval comfort nursing measure in protective restraint for manic patients in Department of Neurosurgery.Methods From January 2014 to July 2016, a total of 86 manic patients with protective restraint in the department of neurosurgery of Huai'an First People's Hospital Affiliated to Nanjing Medical University were selected as the research object by purposive sampling method. All of them were randomly divided into the intervention group and the control group according to the random table method, 43 cases in each group. The patients of control group were treated with conventional protective measures. On the basis of the conventional protective restraint, the patients of intervention group adopted the interval comfortable nursing measures. We compared the incidence of unplanned extubation in the two groups and compared the difference between the two groups in terms of the restraint effect and the satisfaction degree of comfort care among doctor, nurse and patient.Results The incidence of unplanned extubation in the intervention group (11.63%) was significantly lower than that of control group (53.68%)(P<0.05). The incidence of incomplete skin, poor peripheral blood flow, restraint band breaking and the restraint time in intervention group were lower than those of control group (P<0.05). The comfort, family satisfaction and nurse satisfaction of the intervention group were higher than those of the control group (P <0.05).Conclusions The interval comfort nursing can reduce unplanned extubation rate of patients with manic disorder in department of neurosurgery, improve skin integrity, promote peripheral blood flow, reduce constraint time and perfect patient's satisfaction.

ObjectiveTo discuss the effects of continuing nursing on the living condition of patients with severe craniocerebral injury in neurosurgery department.Methods A total of 303 patients with severe craniocerebral injury from January 2008 to December 2009 in neurosurgery department of Huai'an First People's Hospital,Nanjing Medical University were randomly divided into the control group (140 cases) and the intervention group (163 cases). Patients in the control group were followed up once by the phone at the first week after discharge. There was no longer follow-up after the first week and patients could call or visit hospital in case of problems. Patients in the intervention group received continuing nursing intervention by telephone follow-up visit,the establishment of continuing nursing WeChat group,family visit and the establishment of brain club. Patients were followed up from the first week after discharge until the death of patients or December 2015. Survival rate of two groups was evaluated by survival analysis.Results The survival rate of patients in the intervention group and the control group were 78.8% and 62.3%,which were calculated by the Kaplan-Meier method. The survival rate of patients in the intervention group was significantly higher than that in the control group (χ2=33.91,P<0.05).Conclusions Continuing nursing helps to improve the survival situation of patients with severe craniocerebral injury in the process of time.

Objective:To investigate the effects of microRNA (miR) -125b on the proliferation and phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway of hepatocellular carcinoma (HCC) cell by targeting Polo like kinases (PLK4).Methods:The tumor tissues and adjacent tissues of 65 patients with HCC were collected from March 2022 to March 2023 in Tianjin Medical University Cancer Hospital, including 33 males and 32 females, aged (60.1±5.6) years. The expressions of miR-125a and miR-125b in liver cancer, adjacent tissues and liver cancer cells were detected by fluorescence quantitative polymerase chain reaction. Low expression liver cancer cell was selected to transfect negative control (NC) sequences of miR, miR-125a and miR-125b. Subsequently, miR-NC and NC plasmid, miR-125b sequence and NC plasmid, and miR-125b sequence and PLK4 plasmid were co-transfected. Cell proliferation was detected by cell counting assay, the expression of PLK4, phosphorylated PI3K (p-PI3K) and phosphorylated Akt (p-Akt) was detected by Western blot, and miR-125b-targeting PLK4 were detected by bioinformatics analysis and dual luciferase reporter gene.Results:The relative expressions of miR-125a and miR-125b in HCC patients were (0.62±0.08) and (0.58±0.07), respectively, lower than those in adjacent tissues (1.00±0.12) and (1.00±0.13), and the differences were statistically significant ( t=21.24, 22.93, P=0.005, P<0.001). HepG2 cells with low expression of miR-125a and miR-125b and miR-125b targeting PI3K/Akt were selected for transfection. Bioinformatic analysis and dual luciferase reporter gene assay confirmed that miR-125b binds to PLK4. Overexpression of miR-125b could inhibit the proliferation of HepG2 cells and the expression of p-PI3K and p-Akt, while overexpression of PLK4 could partially reverse the proliferation inhibition caused by miR-125b and the expression of p-PI3K and p-Akt, (0.91±0.07) vs(0.41±0.04), (0.97±0.08) vs (0.32±0.03)( t=13.87, 17.01, both P<0.001). Conclusion:The inhibitory effect of miR-125b on HepG2 cell proliferation and PI3K/Akt signaling pathway is partly mediated by targeted inhibition of PLK4.

Objective:To assess the clinical effectiveness and safety of Omalizumab for treating pediatric allergic asthma in real world in China.Methods:The clinical data of children aged 6 to 11 years with allergic asthma who received Omalizumab treatment in 17 hospitals in China between July 6, 2018 and September 30, 2020 were retrospectively analyzed.Such information as the demographic characteristics, allergic history, family history, total immunoglobulin E (IgE) levels, specific IgE levels, skin prick test, exhaled nitric oxide (FeNO) levels, eosinophil (EOS) counts, and comorbidities at baseline were collected.Descriptive analysis of the Omalizumab treatment mode was made, and the difference in the first dose, injection frequency and course of treatment between the Omalizumab treatment mode and the mode recommended in the instruction was investigated.Global Evaluation of Treatment Effectiveness (GETE) analysis was made after Omalizumab treatment.The moderate-to-severe asthma exacerbation rate, inhaled corticosteroid (ICS) dose, lung functions were compared before and after Omalizumab treatment.Changes in the Childhood Asthma Control Test (C-ACT) and Pediatric Asthma Quality of Life Questionnaire (PAQLQ) results from baseline to 4, 8, 12, 16, 24, and 52 weeks after Omalizumab treatment were studied.The commodity improvement was assessed.The adverse event (AE) and serious adverse event (SAE) were analyzed for the evaluation of Omalizumab treatment safety.The difference in the annual rate of moderate-to-severe asthma exacerbation and ICS reduction was investigated by using t test.The significance level was set to 0.05.Other parameters were all subject to descriptive analysis.A total of 200 allergic asthma patients were enrolled, including 75.5% ( n=151) males and 24.5% ( n=49) females.The patients aged (8.20±1.81) years. Results:The median total IgE level of the 200 patients was 513.5 (24.4-11 600.0) IU/mL.Their median treatment time with Omalizumab was 112 (1-666) days.Their first dose of Omalizumab was 300 (150-600) mg.Of the 200 cases, 114 cases (57.0%) followed the first Omalizumab dosage recommended in the instruction.After 4-6 months of Omalizumab treatment, 88.5% of the patients enrolled ( n=117) responded to Omalizumab.After 4 weeks of treatment with Omalizumab, asthma was well-controlled, with an increased C-ACT score [from (22.70±3.70) points to (18.90±3.74) points at baseline]. Four-six months after Omalizumab administration, the annual rate of moderate-to-severe asthma exacerbation had a reduction of (2.00±5.68) per patient year( t=4.702 5, P<0.001), the median ICS daily dose was lowered [0 (0-240) μg vs. 160 (50-4 000) μg at baseline] ( P<0.001), the PAQLQ score was improved [(154.90±8.57) points vs. (122.80±27.15) points at baseline], and the forced expiratory volume in one second % predicted (FEV 1%pred) was increased [(92.80±10.50)% vs. (89.70±18.17)% at baseline]. In patients with available evaluations for comorbidities, including allergic rhinitis, atopic dermatitis or eczema, urticaria, allergic conjunctivitis and sinusitis, 92.8%-100.0% showed improved symptoms.A total of 124 AE were reported in 58 (29.0%) of the 200 patients, and the annual incidence was 0(0-15.1) per patient year.In 53 patients who suffered AE, 44 patients (83.0%) and 9 patients (17.0%) reported mild and moderate AE, respectively.No severe AE were observed in patients.The annual incidence of SAE was 0(0-1.9) per patient year.Most common drug-related AE were abdominal pain (2 patients, 1.0%) and fever (2 patients, 1.0%). No patient withdrew Omalizumab due to AE. Conclusions:Omalizumab shows good effectiveness and safety for the treatment of asthma in children.It can reduce the moderate-to-severe asthma exacerbation rate, reduce the ICS dose, improve asthma control levels, and improve lung functions and quality of life of patients.
