Objective To explore changes humoral immune factors and MDA in DEACMP patients.Methods 40 cases with carbon monoxide poisoning delayed brain were selected to be experiment group.40 cases of healthy people were selected to be control group.IL-2,IL-6,IL-10 and MDA were before and after treatment.Results IL-2,IL-6 of the experiment group were lower,IL-10,MDA were higher than the control group before treatment (P<0.05),both of IL-2,IL-6,IL-10 and MDA were recovery after the treatment (P<0.05).IL-6 of the experiment before treatment was significantly correlated with MMSE score(r =0.34,P <0.05).More severe cognitive impairment, the higher the level of concentration of IL-6(P<0.05). Conclusion The immune inflammatory cytokines and MDA play an important role in acute carbon monoxide poisoning delayed encephalopathy pathogenesis.Detection of the levels for judging the severity of the patient’s condition and prognosis has important significance.

Objective:To develop couples′ communication quality scale for gynecological cancer patients and test its reliability and validity in accordance with Chinese cultural background.Methods:The scale was initially formed by literature review and Delphi expert consultation. From May to November in 2021, the scale was initially formed by literature review and Delphi expert consultation. A cross-sectional survey of 360 gynecologic cancer patients in Qilu Hospital, Shandong University was conducted from May to August 2021 using a convenience sampling method, and after pretesting, item analysis and exploratory factor analysis were used to screen the scale items. After the formal scale was formed, 385 gynecological cancer patients from Qilu Hospital, Shandong University were conveniently selected for formal testing from September to November 2021, and the reliability and validity of the scale was tested.Results:The formal couples′ communication quality scale for gynecological cancer patients was composed of 34 items from 5 dimensions of "self-disclosure", "perceived response", "stress coping", "normal creation" and "constructive action", with a cumulative variance contribution rate of 68.181%. The Cronbach α coefficient of the scale was 0.949, the split-half reliability coefficient was 0.766, the retest reliability coefficient was 0.898, and the criterion validity coefficient was 0.696. The model′s χ2/ df was 1.778, root mean square error of approximation was 0.047, comparative fit index was 0.956, incremental fix index was 0.956, Tucker-Lewis index was 0.952, normal of fit index was 0.905. Conclusions:The scale can be used to evaluate the quality of couples′ communication among gynecological cancer patients in Chinese context with good reliability and validity.

Objective: To investigate the etiology, diagnosis and treatment principles of inherited permanent tooth embryo necrosis caused by alveolar bone resorption due to severe periapical periodontitis of deciduous teeth, in order to provide a reference for clinical diagnosis and treatment Methods: The clinical data and related literature of a rare case of permanent tooth embryo necrosis were analyzed retrospectively. Results : This case was a 5-year-old girl. Physical examination and X-ray examination revealed chronic periapical inflammation in 75. X-ray showed that the periodontal bone of tooth 75 was extensively destroyed; additionally, the permanent tooth germ of tooth 35 was incomplete and the development was delayed compared to that of tooth 45 because of severe periapical periodontitis in the primary teeth. The initial diagnosis was that-- the embryo of tooth 35 stopped developing due to inflammation and was necrotic after tooth 75 was extracted. The postoperative pathological examination report showed that most bone around the embryos of tooth 35 was sequestrated. Through literature review and analysis, it was found that the degree of periapical lesions in the primary teeth and the developmental stage of the tooth embryo have a great impact on the formation of permanent tooth embryos. Conservative methods such as root canal therapy are usually adopted as treatment. Permanent tooth embryo necrosis caused by periapical periodontitis of deciduous teeth is rare in the clinic, so it is necessary to judge the degree of inflammatory infiltration and of tooth embryo damage as soon as possible according to the clinical symptoms and imaging manifestations; and to make a correct treatment plan. Conclusion There are no objective and clear diagnostic and treatment criteria for the clinical diagnosis of the pathological state of permanent tooth embryo, thus, methods such as etiology elimination and follow-up observation are usually adopted for abnormal permanent tooth embryo development. Future research should focus on prevention and finding addtional effective methods for diagnosis and treatment.

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.
