Objective     To investigate the risk factors for postoperative complications Clavien-Dindo classification≥grade Ⅱ after lung cancer surgery. Methods     The patients who underwent lung cancer surgery in a multicenter observational study from November 2017 to January 2020 were included. The Clavien-Dindo classification of postoperative complications was analyzed. Logistic regression was used to identify the risk factors for complications≥ gradeⅡ. Results     A total of 388 patients were enrolled, including 203 males and 185 females with a mean age of 56.14±10.36 years. The incidence of postoperative complications was 25.52% (99/388) after lung cancer surgery and the incidence of complications≥gradeⅡ was 20.10% (78/388). The five most common postoperative complications were pneumonia (6.96%), prolonged pulmonary air leak (>7 days, 5.67%), incision dehiscence (4.64%), arrhythmia (3.87%), and postoperative pleural effusion (3.35%). Multivariate analysis showed that open surgery [reference: uniportal thoracoscopic surgery, OR=2.18, 95%CI (1.01, 4.70), P=0.047], extended resection [reference: sublobar resection, OR=2.86, 95%CI (1.11, 7.19), P=0.030; reference: lobectomy, OR=2.20, 95%CI (1.10, 4.40), P=0.026] and operative time≥3 h [OR=2.07, 95%CI (1.12, 3.85), P=0.021] were independent risk factors for postoperative complications≥gradeⅡ after lung cancer surgery. Conclusion     Surgical approach, extent of resection and operative time are independent influencing factors for postoperative complications≥gradeⅡ after lung cancer surgery.

Objective:To investigate the clinical characteristics of central nervous system tuberculosis in adults and the possible factors affecting the mortality and disability of the patients.Methods:The clinical data of patients diagnosed as "tuberculous meningitis" "tuberculous meningoencephalitis" "tuberculous cerebrospinal meningitis" or "tuberculous brain ubscess" in Huashan Hospital, Fudan University and Jing′an Branch, Huashan Hospital, Fudan University in Shanghai from January 1, 2010 to December 31, 2017 were collected, and a retrospective cohort was established. The clinical characteristics were analyzed, Medical Research Council (MRC) grade system was used to assess the severity of meningitis, and the modified Rankin Scale was used to assess the impairment of self-care. Survival rate and disability rate of the cohort were analyzed. Binary logistic regression was used for multivariate analysis. Kaplan-Meier survival curve was used for survival analysis.Results:A total of 161 patients with central nervous system tuberculosis were enrolled. Among the 161 patients, 55 cases (34.2%) were confirmed, 72 cases (44.7%) were highly suspected and 34 cases (21.1%) were suspected diagnosis. There were 56 cases (34.8%) with MRC grade Ⅰ, 76 cases (47.2%) with MRC grade Ⅱ and 29 cases (18.0%) patients with MRC grade Ⅲ before treatment. Up to January 1, 2019, ten (6.2%) patients died, 32 (19.9%) patients lost to follow-up, 119 (73.9%) patients survived. The five-year survival rate was 92.83%. There were 72 patients with no impact on life, 34 patients with moderate impact and 13 patients with severe impact. The disability rate was 39.5% (47/119). Binary logistic regression analysis showed that increasing age (odds ratio ( OR)=1.06, 95%confidence interval ( CI) 1.00 to 1.13, P=0.032) and deterioration of MRC grade during anti-tuberculosis treatment ( OR=89.00, 95% CI4.46 to 1 779.00, P=0.003) were independent risk factors for death. When severe disability and death were used as adverse outcomes, logistic regression analysis showed increasing age ( OR=1.07, 95% CI 1.01 to 1.13, P=0.035) and deterioration of MRC grade during anti-tuberculosis treatment ( OR=77.17, 95% CI4.45 to 1 337.00, P=0.003) were still independent risk factors for adverse outcomes. Conclusions:The mortality of central nervous system tuberculosis in adults in this cohort is relatively low, but the disability rate is still high. Increasing age and deterioration of MRC grade during anti-tuberculosis treatment are independent risk factors for death and disability.

Objective:To investigate the clinical characteristics and prognostic factors of 2019 novel coronavirus (2019-nCoV) Omicron variant infected cases.Methods:A total of 987 coronavirus disease 2019 (COVID-19) adult imported cases admitted to Shanghai Public Health Clinical Center, Fudan University from July 1, 2021 to January 6, 2022 were recruited. The cases were divided into Omicron group (193 cases) and non-Omicron group (794 cases) according to the genotype of the virus. The clinical data, imaging examination and laboratory results of two groups were collected and compared. Chi-square test and Mann-Whitney U test were used as statistical methods. Multiple linear regression analysis was used for multiple linear regression analysis. Results:The majority of patients in Omicron group were 18 to 30 years old, accounting for 51.3%(99/193), which was higher than 31.4%(249/794) in non-Omicron group. The difference was statistically significant ( χ2=52.75, P<0.001). The proportion of mild cases in Omicron group was 88.6%(171/193), which was higher than 81.6%(648/794) in non-Omicron group. The difference was statistically significant ( χ2=5.37, P=0.021). Cases with symptoms were more common in Omicron group than those in non-Omicron group (60.1%(116/193) vs 29.1%(231/794)), and the difference was statistically significant ( χ2=65.49, P<0.001), with the main clinical manifestations of sore/itchy throat, fever and cough/expectoration. The proportion of cases with pulmonary computed tomography (CT) imaging manifestations at admission in Omicron group was 13.0%(25/193), which was lower than that in non-Omicron group (215/794, 27.1%). The difference was statistically significant ( χ2=16.83, P<0.001). The proportion of cases with 2019-nCoV IgG positive at admission was 47.7%(92/193) in Omicron group, which was lower than 61.1%(485/794) in non-Omicron group, and the difference was statistically significant ( χ2=11.51, P<0.001). The hospitalization time of Omicron group was 20.0 (16.0, 23.0) d, which was longer than that of non-Omicron group (14.0 (10.0, 22.0) d), and the difference was statistically significant ( Z=-7.42, P<0.001). Multiple linear regression analysis showed that the time of hospitalization of cases with 2019-nCoV IgG positive at admission was shorter, while that of the cases with fever in Omicron group was longer (both P<0.050). Conclusions:The main clinical characteristics of cases with Omicron variant are fever and upper respiratory symptoms. Their pulmonary CT imaging manifestations are less, and the time of hospitalization is slightly longer. The time of hospitalization and the virus clearance time in Omicron variant infected cases with 2019-nCoV IgG positive at admission and not presented with fever are both shorter.

OBJECTIVE: To assess the predictors and outcomes of acute kidney injury (AKI) among patients with coronavirus disease 2019 (COVID-19). OBJECTIVE: This retrospective observational study was conducted among patients with a confirmed diagnosis of COVID-19 admitted to Hankou Hospital between January, 5 and March 8, 2020. We evaluated the association of AKI with the demographic and biochemical parameters and clinical outcomes of the patients using univariate regression analysis. OBJECTIVE: Atotal of 287 COVID-19 patients, including 55 with AKI and 232 without AKI, were included in the analysis. Compared with the patients without AKI, the patients with AKI were older, predominantly male, and were more likely to have hypoxia and pre-existing hypertension and cerebrovascular diseases. The patients with AKI also had higher levels of white blood cells, D-dimer, aspartate aminotransferase, total bilirubin, creatine kinase, lactate dehydrogenase, procalcitonin, C-reactive protein, a higher prevalence of hyperkalemia, lower lymphocyte counts, and higher chest computed tomographic scores. The incidence of stage 1 AKI was 14.3% and that of stage 2 or 3 AKI was 4.9%. The patients with AKI had much higher mortality rate than those without AKI. OBJECTIVE AKI is an important complication of COVID-19. An older age, a male gender, multiple pre- existing comorbidities, lymphopenia, increased infection indicators, elevated D-dimer, and impaired heart and liver functions are all potential risk factors ofAKI. COVID- 19 patients with AKI that progresses into stages 2 or 3 AKI have a high mortality rate. Prevention of AKI and monitoring kidney function is critical in the care of COVID-19 patients.

Wuhan is the city with the most serious outbreak of corona virus disease 2019 (COVID-19) in China. The outbreak of community has exhausted the current medical resources. With integrating local and support medical resources from other province, Wuhan City has rapidly rebuilt a new emergency medical system of classified treatment, and effectively responded to the overload medical demand after the outbreak in the community.

Objective:To take a broad overview of the current allocation of diagnosis and treatment resources and management for patients with tuberculous meningitis (TBM) in 49 hospitals in China.Methods:A cross-sectional survey about TBM was carried out in 49 hospitals from 27 provinces across China, by means of electronic questionnaire.The electronic questionnaire was filled by doctors in charge of the departments where TBM patients were routinely admitted from September to December 2018. The availability of medical resources, diagnosis, evaluation, treatment and surveillance in these hospitals were analyzed from the questionnaire. The count data were expressed as percentage.Results:Among the 49 participating hospitals, 37(75.5%) hospitals had less than 50 admissions of suspected TBM per year. Less than 20 TBM patients were confirmed by etiological diagnosis per year in 42(85.7%) participating hospitals.The availability of conventional medical imaging including computed tomography (CT), magnetic resonance imaging (MRI), enhanced MRI, cerebral angiography and magnetic resonance angiography (MRA) were 100.00%(49/49), 95.92%(47/49), 91.84%(45/49), 61.22%(30/49) and 67.35%(33/49), respectively. The rate of access to classic etiological diagnostic methods including acid-fast bacilli smear, mycobacterial culture and T cell spot test of tuberculosis infection were 77.55%(38/49), 95.92%(47/49) and 83.67%(41/49), respectively. Rifampin (100.0%, 49/49), isoniazid (100.0%, 49/49), pyrazinamide (98.0%, 48/49) and ethambutol (95.9%, 47/49) were most commonly used in initial anti-tuberculosis treatment of non-severe patients with TBM. The course of anti-tuberculosis treatment was 18 months in 25(51.0%) hospitals, and 12 months in 17(34.7%) hospitals. Intrathecal glucocorticoid and isoniazid were used in 39(79.6%) hospitals. Dexamethasone was used as part of treatment in 24(49.0%) hospitals, and the duration of glucocorticoid was about two months in 28(57.1%) hospitals. As for hyponatremia, 32(65.3%) hospitals didn′t investigate the cause, and hypertonic saline (83.7%, 41/49) and oral rehydration salts (71.4%, 35/49) were considered as the most common treatment strategy. Lumbar puncture was most commonly used for intracranial pressure surveillance in 48(98.0%) hospitals.Conclusions:The TBM cases admitted to the investigation hospitals are characterized by scattered sources and few confirmed cases of etiology. There are obvious heterogeneities in the diagnosis and treatment of TBM and the management of complications.The standardized plan for diagnosis and treatment of TBM are needed to improve the management.

Objective: To explore the effect of modified cold therapy instrument on postoperative pain and swelling of patients with tibiofibular fracture. Methods: Eighty patients with tibia and fibula fracture who underwent surgery in Changzhou Cancer Hospital from June 2016 to June 2017 were selected and divided into control group and experimental group according to random number table method, 40 cases in each group. Patients in the control group were treated with conventional ice care, and the experimental group was treated with a modified cold therapy device. The Numerical Rating Scale (NRS) scores, tension blisters and skin dermatoglyphics, swelling and complications were observed before and after treatment. Results: Before the intervention, the difference in pain score and swelling degree between the two groups was not statistically significant (P>0.05). After nursing intervention, the pain scores of the two groups decreased, but the score of the experimental group was 2.2 ± 0.3, which was significantly lower than that of the control group (3.6 ± 0.5) (t= 15.185, P < 0.05); the incidence of tension blisters, the incidence of dermatoglyph and moderate swelling in the experimental group were 10% (4/40), 77.5% (31/40), 10% (4/40), which were lower than 30% (12/40), higher than 50% (20/20), less than 27.5% (11/40) of the control group (χ²= 5.000, 6.545, 4.021, P<0.05); no complications such as deep vein thrombosis and compartment syndrome were found in both groups. Conclusion The improved cold therapy device cold compress is better than the conventional ice dressing treatment, and can reduce the swelling and pain degree of the patients with tibiofibular fracture, which is beneficial to the rehabilitation of the patient and is worthy of clinical application.

Objective This study aimed to investigate the clinical characteristics of cryptogenic stroke as the first manifestation of occult systemic malignancy (OSM) and to determine whether plasma D-dimer levels and lesions in multiple vascular regions could predict occult systemic malignancy in patients with cryptogenic stroke. Methods Data from 83 patients including 9 patients with OSM and 74 patients without OSM were extracted from the stroke database of Beijing Shijitan Hospital. Clinical variables were analyzed between cryptogenic stroke patients with OSM and without OSM. The relationshiop between plasma D-dimer levels or lesions in multiple vascular regions and OSM were analyzed by multiple logistic regression analysis. Results Compare to patients without OSM, patients with OSM was older (66.8± 7.5 vs.56.4±15.7,P=0.004)and had lower hemoglobin levels (127.9±19.8 vs.143.6±17.7,P=0.015),higher conut score [3(1,3) vs. 1(0,2), P=0.011], higher plasma D-dimer levels (77.7% vs. 13.5%, P<0.001) and more common lesions in multiple vascular regions(100% vs.23.0%, P<0.001).Multiple logistic regression analysis revealed that high plasma D-dimer levels are independent risk factors for OSM (OR=26.250,95%CI:3.041-226.604,P=0.003).Conclusions Patients with OSM are elderly people and have poorer nutritional status, higher plasma D-dimer levels and more common lesions in multiple vascular regions. High plasma D-dimer levels can be useful to predict OSM in patients with cryptogenic stroke at earlier stages.

Objective To explore the effects of automatic and intelligent micro pump in changing vasoactive agents. Methods This research selected 60 patients with a great number of vasoactive agents (dopamine or adrenalin hydrochloride) after cardiac surgery of Cardiovascular Surgery in Chinese PLA General Hospital from April to November 2016. Those patients were divided into experimental group (n=30, changing agents with the automatic and intelligent micro pump) and control group (n=30, changing agents with the traditional method of dual pump). The fluctuation of blood pressure (BP) of patients between two groups was compared before and after changing agents. Results There was no significant difference in BP of both group patients before changing vasoactive agents (P> 0.05). The mean BP of patients in the control group was significantly higher than that in the experimental group 30 seconds after changing vasoactive agents (P=0.011). The degree of fluctuation of BP of patients in the control group was greater than that in the experimental group 30 seconds and one minute after changing agents with a significant difference (P<0.05). Conclusions The automatic and intelligent micro pump has a big advantage in maintaining a stable BP during changing agents by pump. It is worth to be used widely in clinical application.

Objective To construct and implement the nursing quality information feedback system based on QUACERS model and control theory, and discuss its application effect and the problems that should be paid attention to and to provide operational cases and practical basis for nursing quality management. Methods Through literature review and expert consultation, the framework and content of nursing quality information feedback system were set up and implemented. The changes of the nursing quality and the repeated occurrence of nursing problems were evaluated before (2013) and after (2015) the implementation of this project. And in December 2015, a self-made questionnaire was conducted among the nurses in the hospital to evaluate the importance of the feedback and it′s effect of improving the nursing quality. And evaluate the timeliness and effectiveness of different feedback forms. Results 1 120 and 1 136 nurses were followed-up in 2013 and 2015 respectively. The scores of human resource management, clinical nursing service and nursing safety management were higher than before, and the repeated occurrence of nursing problems was lower than before. A total of 450 questionnaires were distributed, 438 copies were collected, the effective recovery rate was 97.33%. Ratings for the importance of each item was from 3.37 to 4.57. Ratings for the effect of improving the quality of care was 3.79 to 4.39. The percentage of quality information received by nurses was more than 95%, and the average score of feedback timeliness was 4.29 to 4.53. Conclusions Quality information feedback system based on QUACERS model can cover multiple dimensions of quality management, and it was conducive to obtaining comprehensive information;Combined with multiple feedback forms can improve the effect of information feedback.
