Objective:To explore the effect of acute kidney injury(AKI)on near-term survival after lung transplantation(LT)in patients with idiopathic pulmonary fibrosis(IPF).Methods:Through consulting electronic medical records, anesthetic modes and Chinese Lung Transplant Registration System, clinical data are retrospectively reviewed for 275 IPF patients undergoing LT at Affiliated Wuxi People's Hospital of Nanjing Medical University from January 2017 to April 2021.According to the diagnostic criteria of Kidney Disease: Improving Global Outcomes(KDIGO), they are divided into two groups of AKI(169 cases)and non-AKI(106 cases).Perioperative findings of two groups are recorded.Then univariate and multivariate Cox regression models are employed for determining whether or not inter-group differences existed in survival rates post-LT.Also AKI is staged according to the KDIGO.And the effect of stage 1/2/3 AKI on near-term postoperative prognosis is examined.Results:The differences are significantly different in recipient gender, creatinine, 6-minute walking test, forced vital capacity(FVC), lung allocation score, oxygenation index, N-terminal pro-brain natriuretic peptide(NT-Pro BNP), preoperative hormone use and volume of crystal infusion( P<0.05).After multivariate Cox regression correcting for covariates, no statistical significance exists in effect of AKI stage 1 on near-term postoperative survival rate( P<0.05).AKI stage 2/3 still has statistical significance in risk of mortality at Day 30/90/180/365 post-operation( P>0.05). Conclusions:As a common complication post-LT, AKI significantly affects near-term postoperative prognosis of transplant IPF patients.Stage 2/3 AKI impacts near-term postoperative survival while stage 1 AKI is not associated with higher mortality.

The current organ allocation rules prioritize elderly and urgent patients on the lung transplantation (LT) waiting list. A steady increase in the threshold at which age is taken into consideration for LT has been observed. This retrospective cohort study recruited 166 lung transplant recipients aged ≽ 65 years between January 2016 and October 2020 in the largest LT center in China. In the cohort, subgroups of patients aged 65-70 years (111 recipients, group 65-70) and ≽ 70 years (55 recipients, group ≽ 70) were included. Group D restrictive lung disease was the main indication of a lung transplant in recipients over 65 years. A significantly higher percentage of coronary artery stenosis was observed in the group ≽ 70 (30.9% vs. 14.4% in group 65-70, P = 0.014). ECMO bridging to LT was performed in 5.4% (group 65-70) and 7.3% (group ≽ 70) of patients. Kaplan-Meier estimates showed that recipients with cardiac abnormalities had a significantly increased risk of mortality. After adjusting for potential confounders, cardiac abnormality was shown to be independently associated with the increased risk of post-LT mortality (HR 6.37, P = 0.0060). Our result showed that LT can be performed in candidates with an advanced age and can provide life-extending benefits.

Objective:To explore the spatial autocorrelation and macro influencing factors of stroke mortality in Zhejiang Province in 2015-2020 and provide a scientific basis for stroke prevention and control strategy.Methods:The data on stroke death were obtained from Zhejiang Chronic Disease Surveillance System. The spatial distribution of stroke mortality was explored by mapping and spatial autocorrelation analysis. The spatial panel model analyzed the correlation between stroke mortality and socioeconomic and healthcare factors.Results:From 2015 to 2020, the average stroke mortality was 68.38/100 thousand. The standard mortality of stroke was high in the areas of east and low in the west, high in the south and low in the north. Moreover, positive spatial autocorrelation was observed (Moran's I=0.274-0.390, P<0.001). Standard mortality of stroke was negatively associated with per capita gross domestic product (GDP) ( β=-0.370, P<0.001), per capita health expenditure ( β=-0.116, P=0.021), number of beds per thousand population ( β=-0.161, P=0.030). Standard mortality of ischemic stroke was negatively associated with per capita GDP ( β=-0.310, P=0.002) and standard management rate of hypertension ( β=-0.462, P=0.011). Standard mortality of hemorrhagic stroke was negatively associated with per capita GDP ( β=-0.481, P<0.001), per capita health expenditure ( β=-0.184, P=0.001), number of beds per thousand population ( β=-0.288, P=0.001) and standard management rate of hypertension ( β=-0.336, P=0.029). Conclusions:A positive spatial correlation existed between stroke mortality in Zhejiang Province in 2015-2020. We must focus more on preventing and controlling strokes in relatively backward economic areas. Moreover, to reduce the mortality of stroke, increasing the investment of government medical and health funds, optimizing the allocation of medical resources, and improving the standard management rate of hypertension are important measures.

Objective To identify the risk factors of prolonged mechanical ventilation (PMV) after lung transplantation. Methods Clinical data of 90 recipients undergoing lung transplantation were retrospectively analyzed. According to the duration of invasive mechanical ventilation after operation, all recipients were divided into the PMV group (ventilation duration > 48 h, n=30) and control group (ventilation duration≤48 h, n=60). Perioperative parameters were compared between two groups, including preoperative parameters [serum creatinine, estimated glomerular filtration rate (eGFR)], intraoperative parameters (cold ischemia time of donor lung, blood loss), and postoperative parameters [the first red blood cell, white blood cell, platelet count, hemoglobin, C-reactive protein, serum creatinine, total bilirubin, alanine aminotransferase (ALT), oxygenation index, eGFR and the mean arterial pressure in intensive care unit (ICU)]. The risk factors of PMV after lung transplantation were assessed by multivariate logistic regression analysis. Results Preoperative serum creatinine level in the PMV group was 62 (53, 67) μmol/L, significantly higher than 57 (47, 62) μmol/L in the control group. Preoperative eGFR in the PMV group was 97 (93, 107) mL/min, significantly lower than 106 (102, 116) mL/min in the control group. The first postoperative oxygenation index in the PMV group was 196 (157, 286) mmHg, significantly lower than 250 (199, 354) mmHg in the control group (all P < 0.05). Multivariate analysis showed that the first increase of postoperative total bilirubin, the first decrease of postoperative oxygenation index and preoperative eGFR decrease were the independent risk factors for PMV following lung transplantation. Conclusions The first increase of postoperative total bilirubin, the first decrease of postoperative oxygenation index and preoperative eGFR decrease are the independent risk factors for PMV after lung transplantation.

Objective:To investigate the risk factors and treatment outcome of recurrent Acanthamoeba keratitis (AK) after corneal transplantation. Methods:A serial case-observational study was carried out.Twenty-eight eyes of 28 patients with AK who underwent corneal transplantation in Shandong Eye Hospital from January 2012 to January 2019 were enrolled.All the eyes received corneal transplantation from failing to respond to topical and systemic anti- Acanthamoeba medical therapy, including 13 eyes that received penetrating keratoplasty (PKP) and 15 eyes that received lamellar keratoplasty (LKP). The corneal lesion was removed by a trephine with a diameter of 0.5 mm over infiltration area during PKP or LKP.The clinical features of recurrent AK were summarized, including recurrence time, site and signs, and the risk factors of AK recurrence were analyzed.Local and systemic anti- Acanthamoeba medical therapy was performed in all relapsed eyes, and secondary surgery was performed for the eyes with poor response to medication.The therapeutic outcome of recurrent AK was evaluated.The study adhered to the Declaration of Helsinki.This study protocol was approved by an Ethics Committee of Shandong Eye Hospital (No.201112). Results:In the 28 eyes, 7 eyes (25%) appeared recurrent AK after keratoplasty, including 2 eyes after PKP and 5 eyes after LKP.There was no significant difference in the recurrence rate between the two methods ( P=0.396). The recurrence rate of eyes that had used glucocorticoids drugs before operation was 57.14% (4/7), which was significantly higher in comparison with 14.29% (3/21) of eyes without glucocorticoids before surgery ( P=0.043). The recurrence rate of eyes with ulcer diameter ≥8.2 mm was 50.00% (5/10), which was significantly higher than 11.11% (2/18) of eyes with ulcer <8.2 mm ( P=0.036). The recurrent lesions began at the edge of implant bed accounted for 85.71% (6/7), and the recurrent lesions located below graft accounted for 14.29% (1/7). In 7 eyes with recurrent AK, 6 eyes were completely cured.Among recurrent AK eyes after LKP, 2 eyes were cured by long-term medical therapy, and 2 eyes were cured by extended-diameter LKP, and another 1 eye was cured by conjunctival flap covering surgery.One eye with recurrent AK after PKP was cured by extended-diameter PKP. Conclusions:The risk factors of recurrent AK after surgery are application of glucocorticoids before surgery and big lesions.Recurrent AK after surgery is curable by individualized therapy targeting to different clinical characteristics.

Objective:To explore the indications of lung transplantation for pulmonary interstitial fibrosis after COVID-19 and the precautionary measures of medical staff during operation.Methods:Lung transplantation was performed for three cases of COVID-19 from February 15, 2020 to March 1, 2020. The course of disease, mechanical ventilation time, extra-corporeal membrane oxygenation (ECMO) support time, surgical procedures and precautionary measures of medical staff during operation were analyzed.Results:The course of disease were 40, 7, 39 days, the mechanical ventilation time 26, 22, 27 days and ECMO support time 16, 7, 14 days. The postoperative pathological results of three cases indicated pulmonary interstitial fibrosis. One case died on the operative day and two survivors stayed currently in rehabilitation. Thirty-nine medical staff had no symptoms of COVID-19 after 14 days of isolation. The detection of 2019-nCoV nucleic acid was negative for both nasal and pharyngeal swabs.Conclusions:Patients with pulmonary interstitial fibrosis after COVID-19 show no improvement after 1 month of active medical treatment. And the 1-month risk of mortality was over 50% and nucleic acid of 2019-nCoV turned negative. Lung transplantation might be considered. The triple precautionary levels of medical staff during operation prevented the transmission of 2019-nCoV.

Objective: To learn the willingness and influencing factors of influenza vaccination among the community managed diabetic patients in Keqiao District, Shaoxing, so as to provide the basis for influenza vaccination promotion. Methods: A self-compiled questionnaire survey was conducted from October to December 2017 among all the managed diabetic patients in Keqiao District. The contents of questionnaire included the basic information of the respondents, awareness of influenza vaccine, vaccination status and vaccination intention. Logistic regression model was used to analyze the influencing factors for the willingness of influenza vaccination. Results: A total of 15 060 questionnaires were sent out and 13 781 valid ones were retrieved, the response rate was 91.51%. There were 3 888 patients with the awareness of influenza vaccine, accounting for 28.21%; 4 259 patients with the willingness to be vaccinated, accounting for 30.90%; 630 previously-vaccinated patients, accounting for 4.57%. The patients who were female (OR=1.157, 95%CI: 1.064-1.258) , were married (OR=1.242, 95%CI:1.107-1.393), were with other chronic diseases (OR=1.199, 95%CI: 1.103-1.303) , believed diabetic patients were more susceptible to influenza (OR=1.251, 95%CI: 1.102-1.419) , believed influenza aggravate diabetes status (OR=1.640, 95%CI: 1.445-1.860) , believed that the vaccination effectively prevent influenza (OR=3.129, 95%CI: 2.866-3.416) , knew about influenza vaccine (OR=1.111, 95%CI: 1.105-1.216) and ever received influenza vaccination (OR=1.316, 95%CI: 1.103-1.570) were more willing to be vaccinated. Conclusions The willingness of influenza vaccination among the community managed diabetic patients in Keqiao District is low. The patients＇gender, married status, other chronic diseases, awareness of influenza vaccine and the history of vaccination can affect the willingness of influenza vaccination.

Objective : To explore the positive rates and influencing factors of depression and anxiety among managed diabetic patients in community and to provide evidence for the future mental health intervention. Methods: Random sampling method was used to select the diabetic patients from the local health information platform in Ningbo. The anxiety and depression symptoms of the diabetic patients were evaluated by 9-Item Patient Health Questionnaire（PHQ-9）and 7-Item Generalized Anxiety Disorder Scale（GAD-7）. Logistic regression model was applied to analyzing the influencing factors for anxiety and depression in diabetic patients. Results: A total of 1 032 diabetic patients were enrolled,with a response rate of 91.98%. The positive rate of depression was 9.01% and the positive rate of anxiety was 3.78%. The results of multivariate logistic regression analysis showed that divorced/widowed（OR=3.046,95%CI：1.522-6.100）,having two comorbidities or more（OR=6.723,95%CI：2.495-18.120）and suffering diabetes for more than ten years（OR=2.668,95%CI：1.406-5.062）were the risk factors for depression in diabetic patients,while having a college education or above（OR=0.288,95%CI：0.093-0.893）was the protective factor for depression in diabetic patients;unmarried（OR=13.244,95%CI：1.268-138.377）,having two comorbidities or more（OR=6.979,95%CI：2.164-22.503） and suffering diabetes for more than ten years（OR=3.109,95%CI：1.241-7.787）were the risk factors for anxiety in diabetic patients. Conclusion Marital status,the number of comorbidity,course of diabetes and education level could affect the occurrence of depression in diabetic patients;marital status,the number of comorbidity and course of diabetes could affect the occurrence of anxiety in diabetic patients.

Objective To investigate the prevalence characteristics for high risk adults of type 2 diabetes in Zhejiang. Methods From June to October in 2010, 19113 local residents aged≥18 years old were selected among 7571 families from fifteen counties in Zhejiang by a four stage stratified-random sampling method. A self-designed questionnaire was completed to collect information on demographic characteristics, risk factors, and physical activity. At the same time, physical examinations including measurements of height, weight, blood pressure, and blood lipid levels were carried out. The high-risk population was determined according to the 2017 edition of China′s Guidelines for the Prevention and Treatment of Type 2 Diabetes. Results Finally, 17437 people completed all the investigation projects. Among them, 14455 people were at high risk of type 2 diabetes [aged (49.3+15.1) years, 6902 men (47.75％) and 7553 women (52.25％)]. The crude prevalence rate of high risk type 2 diabetes was 82.90％(standardized rate:79.26％). A significantly higher prevalence rate of high risk type 2 diabetes was associated with the age group of 45 to 60 years (83.47％), men (84.49％), class 1 rural area (84.59％), primary school education level (87.04％), marital status (84.40％), and average annual family income less than 10000 yuan (all P<0.05). Among the eight high risk factors, the detection rate of ≥40 years old was the highest (78.12％) and the detection rate of history of cardiovascular disease was the lowest (1.54％). The detection rates of overweight/obesity/central obesity, dyslipidemia, hypertension, sedentary lifestyle, pre-diabetes, and family history of type 2 diabetes were 42.86％, 31.28％, 29.98％, 29.18％, 7.28％, and 3.81％, respectively. High risk of type 2 diabetes was dominated by 1 high-risk factor (31.75％) or 2 high-risk factors (31.39％) or 3 high-risk factors (22.13％). The adults with 4 high-risk factors (11.01％) and 5 or more high-risk factors (3.71％) were less in number. The detection rates of all the risk factors and aggregation distribution of various risk factors were significantly different between different genders, age groups, regions and educational levels, marital status, and family per capita annual income. Conclusion The epidemic level of high-risk type 2 diabetes in Zhejiang province is relatively high, and health management of high risk of type 2 diabetes in community should be actively taken as early as possible according to the population distribution characteristics.

Objective:To understand the oral health status of urban and rural residents in China,the Fourth National Oral Health Epidemiological Survey (FNOHES) was conducted in 2015.Materials and methods:Based on the principles of multi-stage,stratified,equal capacity,and random sampling,the subjects included five groups of residents aged 3-5,12-15,35-44,55-64,and 65-74 years in all 31 provinces,municipalities,and autonomous regions except Hong Kong,Macao,and Taiwan.The total sample size was 172,425.The survey covered two areas,namely oral health status and knowledge,attitude and oral health behavior.Results:Residents in China had serious caries and poor periodontal condition.The prevalence of caries was above 50％ in all age groups,subjects without periodontal disease accounted for ＜50％,and fewer than 50％ of subjects brushed their teeth twice a day.Based on the results of the FNOHES,the following suggestions were proposed for improving the oral health in China in the future:to establish and improve the comprehensive prevention and control system for oral diseases,implement a comprehensive prevention and control strategy for priority groups,strengthen the oral health education for all people to improve oral health literacy,enhance dynamic monitoring to scientifically evaluate oral health status,and coordinate multi-party resources to establish and improve the oral health service security system.Conclusion:The oral health status of Chinese residents and their oral health behavior habits need to be improved.With the support of the administrative departments of the government and unremitting efforts of the oral health staff,all sectors of society must be coordinated to strengthen oral health education for the whole population.Furthermore,comprehensive prevention and control measures must be implemented for priority groups.
