Objective To investigate the complications related factors in infants with mycoplasma pneumonia pulmonary(MPP). Methods According to the condition of pulmonary complications, 105 cases of infants MPP were divided into pulmonary complication group and no pulmonary complication group with 72 cases and 33 cases respectively,and the general related factors and disease related factors of two groups were analyzed. Results The incidence rate of pulmonary complication was 68.6% (72/105) in infants MPP, and the main involved extra-pulmonary systems were digestive system (54.2%), cardiovascular system (44.4%) and blood system(33.3%). Among 20 factors associated with pulmonary complications of MPP, age, feeding method (including artificial, mixing and milk three classification), season of onset, fever days, the titer of mycoplasma pneumonia (MP)-IgM, C-reaction protein, erythrocyte sedimentation rate and the initial time of using macrolides had significant differences between two groups (P<0.05). Multivariate Logistic regression analysis showed that age≥2 years, fever days≥7 d, titer of MP-IgM≥1∶160, increased C-reaction protein levels and accelerated erythrocyte sedimentation rate were the risk factors for pulmonary complications of infants MPP, while breastfeeding and using macrolides within 7 d were the protective factors. Conclusions The incidence rate of pulmonary complications in infants MPP is high, which can affect multiple systems. For children with older age, longer thermal process, higher titer of MP-IgM, and increased C-reaction protein , accelerated erythrocyte sedimentation rate and more past medical history, more attention should be paid for their higher pulmonary complications incidence.

Objective To explore the effect of continued nursing intervention on quality of life of patients with chronic obstructive pulmonary disease. Methods The study took use of randomized controltest. All the 130 patients who were on admission because of acute exacerbation of chronic obstructive pulmonary disease were randomly divided into the intervention group (62 cases) and the control group (68 cases). The intervention group received telephone and home follow-up for one year, and the control group was provided conventional care. Lung function, SGRQ and dyspnea degree were collected on one-month,three-month, six-month, twelve-month after intervention. Results Lung function and activity scores of SGRQ, dyspnea degree and six minutes walk test between two groups had statistical significance after intervention. Conclusions Continued nursing intervention can postpone the rate of FEV1% declining, reduce dysnea degree, decrease the frequency of acute exacerbation, increase the quality of life of COPD patients.

Objective To explore the influencing factors for overtreatment in patients with high-grade squamous intraepithelial lesion(HSIL)on primary cervical cytology diagnosis.Methods Two hundred and thirty-nine patients with initially diagnosed HSIL on cervical cytology and received cervical conization from January 2012 and December 2016 were selected in this study.Overtreatment was defined as he highest level of pathologic diagnosis which was less than or equal to the low-grade squamous intraepithelial lesion(LSIL).The relevance of patients' age,menstrual status,colposcopy finding,the level of high-risk-HPV-DNA and treatment protocol to overtreatment were investigated.Results The most serious pathological diagnosis confirmed that no CIN,LSIL,HSIL,adenocarcinoma in situ(AIS)and squamous carcinoma of cervix(SCC)were detected,with 3.8%(9/239),5.6%(14/239),87.9%(210/239),0.4%(1/239),2.1%(5/239)respectively.The overall overtreatment rate was 9.6%(23/239).The level of high-risk-HPV-DNA and colposcopic findings were significantly related to overtreatment, and colposcopic finding with LSIL was the risk factor for HSIL overtreatment(OR= 8.786,95%CI= 1.671-17.311,P= 0.015),while HPV-DNA≥1000 ng/L was the protective factor(OR=0.201,95%CI=0.043-0.951,P=0.041).Conclusion The level of high-risk-HPV-DNA and the colposcopic finding are the influencing factors for overtreatment in patients with HSIL on primary cervical cytology diagnosis.

The prone position ventilation, as a new type of mechanical ventilation treatment technology, has been widely used in clinical practice. Patient populations and disease types have been obviously expanded. The implementation of the technology needs medical staff's cooperation. The intervention effect, safety and quality critically depend on nursing work. In the whole process, the nursing quality has been put forward higher request. In recent years, increasing scholars have paid attention to the related researches. This paper summarizes the clinical application, nursing points, and the challenges of the prone position ventilation in patients with respiratory failure, in order to provide reference for the development and optimization of the clinical nursing.

Public hospitals reform is a key roadblock for the ongoing health reform.By means of such experiments as Three openings and three mechanisms,Beijing is practicing a separation of hospital regulation and management and separation of clinic and pharmacy,while building the mechanism of financial subscription for pricing,that of medical insurance adjustment,and that of hospital corporate governance.These measures aim at building a new management structure,operation mechanism and medical service model focusing on quality of care,efficiency and satisfaction.Separation of clinic and pharmacy has lowered drug proportion,average outpatient expense and out of-pocket payment of patients,as well as producing higher patient satisfaction,quality of care and hospital income.Other benefits include better management efficiency indirectly caused by separation of clinic and pharmacy,higher acceptance of the corporate governance,and service model innovation to better serve the people.

Objective To explore the effects of heated humidified high flow nasal cannulae (HFNC) oxygen therapy among patients with pulmonary fibrosis. Methods A total of 60 patients in accord with diagnostics guide for idiopathic pulmonary fibrosis and admitted to Department of Respiratory at a Class III Grade A hospital in Tianjin for pulmonary fibrosis were selected by convenience sampling from May 2016 to March 2017. They received oxygen inhalation through nasal cannula for 24 hours and sequentially HFNC oxygen therapy for 24 hours respectively. The blood gas analysis,degree of comfort,severity of dyspnea and incidence of complications were compared two,four and twenty-four hours after adopting oxygen inhalation through nasal cannula and HFNC oxygen therapy. Results There were statistically significant differences in PaO2,SpO2,base excess (BE) and respiratory rate (RR) between oxygen inhalation through nasal cannula and HFNC oxygen therapy (P<0.05). The degree of comfort and severity of dyspnea significantly improved by HFNC oxygen therapy (P<0.05). There was a statistically significant difference in the incidence of complications (P<0.05). However,there was no statistically significant differences in PaCO2and PH between two oxygen methods (P>0.05). Conclusions The application of HFNC can increase PaO2and SpO2,and slow RR among patients with pulmonary fibrosis. Meanwhile,it can also effectively improve the severity of dyspnea,promote patients′ comfort and reduce the incidence of complications.

Objective:To translate the Understanding COPD (UCOPD) into Chinese, culturally adjust it and test its reliability and validity.Methods:According to the translation principle of Brislin questionnaire, the English version of UCOPD was translated, back-translated and culturally adjusted and pre-tested to form the Chinese version of UCOPD. From December 2020 to April 2021, a total of 101 COPD patients admitted to Tianjin Medical University General Hospital were enrolled using the convenient sampling method. The reliability and validity of the scale were tested.Results:The Chinese version of UCOPD included section A and B. Section A included 3 dimensions, such as "about COPD" "managing symptoms of COPD" "accessing help and support", with a total of 18 items. The results of exploratory factor analysis showed that the cumulative variance contribution rate of the three common factors was 59.35%. The Cronbach's α coefficient of section A was 0.893, and the Cronbach's α coefficient of each dimension was 0.756-0.864. The test-retest reliability of section A was 0.954, and the test-retest reliability of each dimension was 0.779-0.887. Section B included 6 items, which were used to measure the satisfaction of pulmonary rehabilitation courses in COPD patients. However there were big individual differences, so the reliability and validity test of section B were not evaluated.Conclusions:Section A of the Chinese version of UCOPD questionnaire has good reliability and validity. It can be used to evaluate self management ability of patients with good knowledge of COPD but less confidence in symptom control and health maintenance, so as to guide clinical medical staff to formulate accurate intervention measures to improve patients' self management.

Objective:To explore effects of different flow rates and temperature settings of high-flow nasal cannula oxygen therapy (HFNC) on patients with mild to moderate community-acquired pneumonia (CAP) accompanied by type I respiratory failure.Methods:Using the convenient sampling method, a total of 92 patients with mild to moderate CAP accompanied by type I respiratory failure who were admitted and received HFNC in the Department of Respiratory and Critical Care Medicine in a Class Ⅲ Grade A hospital in Tianjin were selected as the research objects from December 2019 to December 2020. They were randomly divided into 4 groups, including low temperature and low flow rate group (31 ℃, 30 L/min) , low temperature and high flow rate group (31℃, 50 L/min) , high temperature and low flow rate group (34℃, 30 L/min) , high temperature and high flow rate group (34 ℃, 50 L/min) , with 23 cases in every group. Two-factor factorial analysis of variance was used to compare effects of different flow rates and temperature settings of HFNC on the comfort, oxygenation index, respiratory rate and heart rate of patients with mild to moderate CAP.Results:The comfort level of patients in the low flow rate group (30 L/min) was higher than that of the high flow rate group (50 L/min) , and the comfort level of patients in the low temperature group (31 ℃) was higher than that of the high temperature group (34 ℃) . The differences were statistically significant ( P<0.01) . The oxygenation index of patients in the high flow rate group (50 L/min) was higher than that of the low flow rate group (30 L/min) , and the difference was statistically significant ( P<0.01) . Different flow rates and temperatures of HFNC have no interaction effect on the comfort, oxygenation index and heart rate of patients ( P>0.05) , but they have an interaction effects on respiratory rate ( P<0.01) . Individual effect analysis showed that the respiratory rate of patients in the low temperature and high flow rate group (31 ℃, 50 L/min) was lower than that of the high temperature and high flow rate group (34 ℃, 50 L/min) and the low temperature and low flow rate group (31 ℃, 30 L/min) , and the differences were statistically significant ( P<0.01) . Conclusions:For patients with mild to moderate CAP accompanied by type I respiratory failure, the application of HFNC should start with low temperature and low flow rate parameter settings. Under the condition of ensuring the patient's comfort, the overall effect of flow rate and temperature is integrated and the inhalation flow rate of HFNC is appropriately increased, which can increase the clinical effect of high-flow nasal cannula oxygen therapy.

Objective:To explore the relationships between medical coping modes of patients with COVID-19 and general information and social supports.Methods:From January 28 to February 20, 2020, a total of 128 patients in a designated hospital in Wuhan with novel coronavirus pneumonia were investigated using the General Information Questionnaire and the Chinese version of the Medical Coping Modes Questionnaire (MCMQ) by convenient sampling. Pearson univariate analysis and multiple linear regression were used to analyze the relationship between the basic situation of patients with novel coronavirus pneumonia and coping modes.Results:The scores of the face dimension and avoidance dimension of patients with COVID-19 were lower than the norm model, while the yield dimension was higher than the norm model, and the differences were statistically significant ( P<0.05) . Support utilization and complexity were influencing factors of the face dimension ( P<0.05) . Support utilization and age were influencing factors of the yielding dimension ( P<0.01) . Subjective support, the complexity dimension of disease uncertainty and the number of confirmed patients in the family were influencing factors of the avoidance dimension ( P<0.01) . Conclusions:Patients with COVID-19 have poor medical coping modes, and they are prone to face the disease with a negative attitude. Patients are unwilling to face the disease and the tendency to yield to the disease is greater. And the older the patients, the less likely they are to succumb to the disease. The more patients diagnosed in the family, the less likely they are to avoid the disease. Patients with higher social supports and utilization have a more reasonable medical coping mode. This reminds medical staff to pay more attention to the psychological problems of patients in coping with COVID-19 and improve their coping modes and methods.

Objective:To evaluate the efficacy and safety of oral anisodine hydrobromide tablets in the treatment of nonarteritic anterior ischemic optic neuropathy (NAION).Methods:A multicenter nonrandomized controlled trial was conducted.A total of 282 acute NAION patients (282 eyes) were recruited from 16 hospitals in China from July 2020 to May 2021.Patients were divided into two groups according to treatment methods, which were control group (124 cases, 124 eyes) receiving regular treatment including citicoline sodium plus Ginkgo biloba leaf liquid extract or Ginkgo biloba leaf extract tablets plus mecobalamin, and experimental group (158 cases, 158 eyes) receiving treatment in control group plus oral anisodine hydrobromide tablets 1 mg, twice daily for 2 to 3 months.Best corrected visual acuity (BCVA), visual field index (VFI), peripapillary retinal nerve fiber layer (pRNFL) and radial peripapillary capillary vessel density (RPC) were assessed at 1, 2, 3, and 6 months after enrollment using the standard decimal visual acuity chart, 750i Humphery visual field analyzer, Cirrus HD-OCT 4000/Cirrus HD-OCT 5000, RTVue-XR optical coherence tomography respectively.The primary outcomes were BCVA and VFI, and the secondary outcomes were pRNFL, RPC, and the side effects during the follow-up.The study adhered to the Declaration of Helsinki.All patients were fully informed about the treatment and purpose of this study and voluntarily signed the informed consent form.The study protocol was approved by Chinese PLA General Hospital (No.S2020-021-01). Results:In all, 242 patients (242 eyes) completed the follow-up of BCVA, and 98 patients (98 eyes) completed the VFI follow-up.In terms of visual function, BCVA and VFI improved significantly over time in the two groups, and BCVA and VFI were better in experimental group than in control group at various follow-up time points (all at P<0.05). In terms of structure, pRNFL gradually decreased in both groups with the extension of treatment, and pRNFL was significanthy thinner in experimental group than in control group at various follow-up time points (all at P<0.05). There was no significant difference in RPC between the two groups at the last follow-up ( P>0.05). There were two cases with side effects and one case was discontinued due to side effects 25 days after enrollment. Conclusions:Oral anisodine hydrobromide can improve visual acuity and visual field in NAION and accelerate the regression of optic disc edema, with good safety.
