RESUMEN
Objective: To explore the efficacy and effective node of short-term personalized vestibular rehabilitation (ST-PVR) in treating acute unilateral vestibulopathy (AUVP). Methods: A randomized controlled trial was carried out. The AUVP patients who were admitted to the First Affiliated Hospital of Zhengzhou University from July 2022 to March 2023 were selected and randomized to the vestibular rehabilitation (VR) group and control group via computer-generated randomization. Standard care was the medical treatment with betahistine and prednisolone. Meanwhile, the VR group received ST-PVR. All the patients completed the baseline assessment and underwent follow-up assessments at 1 month and 3 months after the treatment. The assessments were consisted of spontaneous nystagmus (NYS), Romberg test (ROM), head thrust test (HTT), visual analogue scale (VAS) for vertigo, dizziness handicap inventory scale (DHI), activities-specific balance confidence scale (ABC), caloric test using video-electronystagmograph (VNG), and video-head impulse test (vHIT). The measurement data that did not conform to normal distribution were represented by M (Q1, Q3). Generalized estimating equation (GEE) was used to analyze the influence of the ST-PVR on the values of these clinical indicators and the VR grading score. The values of clinical indicators and the VR grading score were compared between the two groups at each follow-up point. Results: Seventy-one AUVP patients were included, with 35 cases in the VR group [14 males and 21 females, aged 51 (33, 55) years] and 36 cases in control group [17 males and 19 females, aged 46 (34, 59) years]. There were statistically significant differences in the impact of ST-PVR on the values of clinical indicators between the two groups (ABC: ß=10.89, P<0.001; VAS: ß=-1.64, P<0.001; DHI: ß=-8.70, P<0.001; NYS: ß=26.73, P<0.001; vHIT: ß=1.41, P=0.047; the VR grading score: ß=1.03, P=0.045). The assessments of the VR group in the positive rate of NYS [14.3% (5/35) vs 50.0% (18/36), P<0.001], ROM [48.6% (17/35) vs 55.6% (20/36), P<0.001], directional preponderance (DP) [34.3% (12/35) vs 75.0% (27/36), P<0.001] and DHI [26 (22, 32) vs 36 (30, 60), P=0.001] were significantly lower than that of the control group at 1 month after the treatment. The results showed a statistically significant difference in ABC [88 (80, 90) vs 76 (61, 88), P<0.001], VAS [2 (1, 3) vs 3 (2, 5), P<0.001] at 3-months after the treatment. The VR grading score of the VR group was improved significantly than those of the control group at 1 month after treatment [21 (17, 21) vs 16 (13, 20), P=0.001]. Conclusion: ST-PVR could improve the results of clinical indicators and VR grading score of the AUVP patients effectively after 1 month of the systematical treatment, and alleviate the symptoms and signs of dizziness in the acute phase as early as possible.

Pulmonary light chain deposition disease (PLCDD) is a rare monoclonal immunoglobulin deposition disease characterized by the deposition of specific immunoglobulin light chains in lung tissue. In its early stages, PLCDD presents with mild clinical symptoms, while pulmonary imaging shows multiple nodules and thin-walled cysts. Pathologically, there is a deposition of eosinophilic amorphous protein-like material in the tissues, which stains negative for Congo red. The exact pathological mechanism of PLCDD remains unclear, and its clinical presentation lacks specificity. Challenges associated with this condition include difficulties in diagnosis, selection and evaluation of treatment options, lack of clear monitoring criteria, and standards for prognosis assessment. Further research is needed to elucidate the pathogenesis of PLCDD, to establish standardized diagnostic and therapeutic protocols, and to evaluate treatment efficacy and prognostic factors.

We reported a case of a 65-year-old male who had been treated with obinutuzumab and chemotherapy for follicular lymphoma. He was infected with SARS-CoV-2 after the second course of therapy. He developed fever, cough and bilateral pulmonary infiltrates. His nasopharyngeal swab became negative only temporarily after repeated courses of antiviral therapy, and the symptoms and pulmonary infiltrates waxed and waned. He presented to our hospital with exertional dyspnea and hypoxemia after his nasopharyngeal swab was positive for SARS-CoV-2 for the fourth time. He had an elevated serum lactate dehydrogenase and a positive 1, 3-ß-D-glucan test. The PCR test for Pneumocystis jirovecii in the sputum was positive. The patient was diagnosed with persistent COVID-19 and Pneumocystis jirovecii pneumonia. He responded well to the combination treatment of antiviral medication, convalescent plasma, trimethoprim-sulfamethoxazole and corticosteroids.

A 58-year-old woman presented with a six-month history of nasal congestion, sore throat and cough, and a five-month history of dyspnea. She had a history of xerostomia for one year. On examination, the bilateral submandibular gland and parotid glands were enlarged. Parotid and anterior cervical lymph nodes were palpable. There were rales in both lungs. The rest of the physical examination was unremarkable. Sialographic analysis showed normal caliber in the main duct, stenosis in secondary ducts, and dilation in the proximal ducts. Minor salivary gland biopsy demonstrated periductal lymphocytic infiltration. Chest computed tomography (CT) showed diffuse thickening of the tracheal and bilateral bronchial walls. Bronchoscopy revealed macroscopic multiple nodules mainly in the trachea and bilateral main bronchus. Endobronchial biopsy showed lymphocytic infiltration in the bronchial submucosa. She was diagnosed with Sjögren's syndrome and treated with glucocorticoids. The dose of prednisone was started at 30 mg/d and tapered gradually. Following treatment, the patient's clinical condition improved dramatically, with shrinkage of the enlarged lymph nodes, bilateral submandibular and parotid glands. A repeated chest CT scan revealed improvement of the tracheal and bilateral bronchial thickening. Multiple nodules in the airway regressed, as evidenced by repeated bronchoscopic examination. The final diagnosis was a large-airway disease associated with Sjögren's syndrome.Among airway diseases in Sjögren's syndrome, peripheral airway diseases including bronchiolitis and bronchiectasis are common; however, central airway lesions in Sjögren's syndrome, especially with macroscopic nodules, are rare. In this case, we demonstrated tracheal and endobronchial nodules in Sjögren's syndrome as determined by clinical features, CT scan, bronchoscopy, and response to therapy.

An elderly woman with a 1-year history of pulmonary shadows was admitted because of intermittent cough and sputum production for 2 months. Chest computed tomography (CT) scans showed bilateral consolidations and ground-glass opacities, with areas of low attenuation inside consolidative opacities on the mediastinal window. Previous history of radiotherapy for nasopharyngeal carcinoma and long-term use of a compound menthol nasal drops provided were important clues to the diagnosis. CT scan-guided needle lung biopsy and bronchoalveolar lavage were performed, and lipid-laden macrophages were confirmed in both bronchoalveolar lavage and lung tissue. Final diagnosis of exogenous lipoid pneumonia was made on the basis of her risk factors for aspiration, history of oil exposure, and classic radiological and histopathological features. Symptoms improved after discontinuation of causative exposure. It is important for clinicians to raise awareness of exogenous lipoid pneumonia and other aspiration lung diseases.

We reported a case of a 36-year-old woman who presented with cough, dyspnea, hypereosinophilia, multiple pulmonary nodules and mediastinal lymphadenopathy. The percentage of eosinophils in bronchoalveolar lavage fluid (BALF) was as high as 65%. Pathogenic tests and cytologic examination of BALF were negative. Transbronchial lung biopsy and endobronchial ultrasound-guided transbronchial needle aspiration revealed only eosinophil infiltration. As the patient responded poorly to high-dose corticosteroids, a surgical lung biopsy was performed. The pathological diagnosis was angioimmunoblastic T-cell lymphoma. The patient received chemotherapy and achieved a partial response. Her eosinophil count returned to the normal range, and the pulmonary nodules on chest CT partially resolved.

Objective: To evaluate the variation of arterial partial pressure of carbon dioxide (PaCO2) in patients with high-risk pulmonary embolism under mechanical ventilation. Methods: We retrospectively analyzed the cases of high-risk pulmonary embolism who underwent intravenous thrombolysis in Peking Union Medical College Hospital from January 1, 2012, to May 1, 2022. The enrolled patients were divided into a mechanical-ventilated group and an active-breathing group according to whether they received invasive mechanical ventilation or not. The level of PaCO2 under active breathing between the two groups, the changes in PaCO2 before intubation, after intubation and after thrombolysis in the mechanical-ventilated group were compared. The 14-day all-cause mortality of the two groups was calculated and compared. Results: A total of 49 patients with high-risk pulmonary embolism were enrolled, including 22 patients in the mechanical-ventilated group and 27 patients in the active-breathing group. Before intubation, PaCO2 in both groups was lower than normal without statistically significant difference between the two groups. After effective thrombolysis therapy, PaCO2 in both groups recovered to the normal range. In the mechanical-ventilated group, PaCO2 significantly increased 11-147 min after intubation and returned to the normal range after thrombolysis therapy. The 14-day mortality in the mechanical-ventilated group was 54.5%, while all patients in the active-breathing group survived. Conclusions: Under mechanical controlled ventilation, patients with high-risk pulmonary embolism could represent hypercapnia which resolved after effective thrombolytic therapy. In mechanical ventilated patients with sudden-onset hypoxemia and hypercapnia, the possibility of high-risk pulmonary embolism should be considered.

A 28-year-old male with a history of leukopenia was admitted with complaints of fever, cough, and dyspnea for 3 months. Initial work-up identified reduced circulating levels of granulocytes, monocytes, lymphocytes, and NK cells. Computed tomography revealed bilateral reticulonodular opacities and mediastinal lymph node enlargement. Peripheral blood culture and mediastinal lymph node aspiration yielded Mycobacterium avium. Genetic testing revealed a heterozygous germline GATA2 mutation (c.1187G>A, R396Q). Despite standard anti-mycobacterial therapy, the patient's dyspnea worsened and subsequent imaging studies revealed diffuse ground-glass opacification. A transbronchial lung biopsy confirmed the development of pulmonary alveolar proteinosis. Bone marrow transplantation had not been performed due to the unavailability of suitable donors. The disease progressed after whole lung lavage, and the patient died at the age of 31 years from respiratory failure. The current case report emphasized the importance of raising awareness about the rare GATA2 deficiency, which is characterized by hematologic abnormalities, primary immunodeficiency, and pulmonary alveolar proteinosis.

Surgical lung biopsy (SLB) has been clearly recommended for the diagnosis of diffuse parenchymal lung disease (DPLD) in major guidelines because it provides the largest and most informative tissue samples. However, with the use of new non-invasive or minimally invasive tools in the diagnosis and treatment of DPLD, the dominance of SLB as the gold standard in the diagnosis of DPLD has been questioned, the diagnostic value of SLB for diffuse parenchymal lung should be re-evaluated.

Objective: To analyse the clinical characteristics and to explore the prognostic factors of acute pulmonary thromboembolism in the elderly. Methods: The medical records of inpatients with acute pulmonary thromboembolism discharged from Peking Union Medical College Hospital from January 1, 2012, to February 1, 2019 were retrospectively reviewed. The eligible patients were divided into elderly group (≥ 60 years old) and non-elderly group (<60 years old). The clinical symptoms, complications, laboratory results, pulmonary embolism severity index (PESI) and mortality were compared between the two groups. Mortality was further compared among elderly patients of different age groups. Cox regression analysis was used to analyze the risk factors of 7-day and 30-day death in elderly patients with pulmonary embolism. Results: A total of 503 patients with acute pulmonary embolism were included, including 279 cases in the elderly group and 224 cases in the non-elderly group. The incidence of cardiac arrest was higher in the elderly group compared with non-elderly group, while the incidence of chest pain and hemoptysis was less common in the elderly group. The proportions of comorbidities, including diabetes, hypertension, and coronary heart disease were higher in the elderly group while the proportion of autoimmune diseases was higher in the non-elderly group. In terms of prognosis, the PESI score and 7-day and 30-day mortality in the elderly group were higher than those in the non-elderly group. The mortality of elderly patients increased with age. Cox univariate regression analysis showed that infection, hypoalbuminemia, hypocalcemia, elevated cardiac troponin(cTnI), elevated N-terminal prohormone of brain natriuretic pepride(NT-proBNP) and PESI grade were associated with 30-day death. Multivariate Cox regression analysis showed that PESI grade and decreased serum calcium concentration were independent risk factors for 7-day death of pulmonary embolism in elderly patients. PESI grade, decreased serum calcium concentration and infection were independent risk factors for 30-day death. Conclusions: The mortality of elderly patients with pulmonary embolism was higher than that of non-elderly patients, and the mortality increased gradually with age. PESI grade, decreased serum calcium concentration and infection were independent risk factors for 30-day death of pulmonary embolism in elderly patients.

We reported a case of vascular Ehlers-Danlos syndrome presenting with recurrent pulmonary hemorrhage. A 22-year-old man was admitted for intermittent hemoptysis and chest pain during the past 18 months. Computed tomography of chest showed bilateral nodules and cavities with halo sign. Inflammatory markers, including erythrocyte sedimentation rate, C reactive protein and interleukin 6, were within normal range. The microbiological and pathological examination of bronchoalveolar lavage fluid and CT-guided percutaneous lung biopsy failed to draw a diagnosis. The pulmonary lesions waxed and waned despite empirical antibacterial, antifungal, antimycobacterial, and anti-parasite treatment. Video-assisted thoracoscopic lung biopsy showed pulmonary hemorrhage, hematoma, ossification, and fibrous nodules, suggesting vascular Ehlers-Danlos syndrome. The molecular testing revealed a heterozygous missense variant in the COL3A1 gene which confirmed the diagnosis of vascular Ehlers-Danlos syndrome. The patient had no skin hyperextensibility or joint hypermobility. During 3-year follow-up, there were no evidence of other vascular or organ involvement except he had intermittent minor hemoptysis. Through this clinical pathological discussion, we aimed to remind pulmonologist to consider the possible diagnosis of vascular Ehlers-Danlos syndrome in young patients with recurrent hemoptysis and waxing and waning pulmonary nodules, cavities, or cysts on CT scan who has neither obvious systematic inflammation nor effective reaction on empirical antimicrobial therapy. Molecular testing should be carried out as soon as possible in a suspected patient to avoid unnecessary invasive examinations.

A 47-year-old man was referred to the pulmonary clinic with a 2-year history of productive cough and 3-month history of hemoptysis. Two years ago, his chest CT scan revealed a 2 cm×2 cm well-defined nodule in the right upper lung. His cough was alleviated without treatment. Three months ago, he had a productive cough with the bloody sputum after a running to catch the bus. Physical examination was normal. Complete blood count (CBC) showed an elevated eosinophil count (42.61%). Chest CT scan showed that the enlargement of the right upper lobe nodule (3.4 cm×3.3 cm), with bilateral pathy lesions distributed in the right upper lobe and the left lower lobe. Pathological study of needle specimen biopsy showed the lamellated cyst wall of hydatid cyst, brood capsule formation and hooklet. Pulmonary hydatidosis was diagnosed. It was recommended that the patient should be treated by surgery combined with albendazole. His symptoms relieved and lung nodules were shrinking without treatment after 5 years follow-up.

Objective: To investigate the changes of disease spectrum in diffuse parenchymal lung disease (DPLD) diagnosed by surgical lung biopsy, and to explore the diagnostic value of surgical lung biopsy in DPLD. Methods: Four hundred and fifty-five consecutive DPLD patients, who underwent surgical lung biopsy in Peking Union Medical College Hospital during the past 28 years, were analyzed retrospectively. Results: There were 211 males and 244 females. The average age at biopsy was (45±14) years. Four hundred and eleven cases (90.3%) were diagnosed by pathologic findings. Four hundred and forty-one cases (96.9%) were diagnosed by clinical-radiologic-pathologic multidisciplinary discussion. The 30-day mortality and 90-day mortality were 2.4% and 3.3% respectively. The disease spectrum included interstitial pneumonia in 209 cases (45.9%) (nonspecific interstitial pneumonia in 105 cases, usual interstitial pneumonia in 33 cases), other miscellaneous DPLD in 166 cases (36.5%) (including hypersensitivity pneumonitis in 49 cases), tumor in 39 cases (8.6%), and infectious diseases in 27 cases (5.9%). In the three consecutive periods (1993-2002, 2003-2012 and 2013-2020), the number of biopsies was 76 (16.7%), 297 (65.3%) and 82 (18%) respectively. The disease spectrum changes over time: in the above three periods, the percentage of interstitial pneumonia in DPLD was 68.4%, 45.1% and 28%, other miscellaneous DPLDs were 22.4%, 39.4% and 39.0%, the tumors were 2.6%, 7.4% and 18.3%, the infectious diseases were 5.3%, 5.1% and 9.8%. Conclusions: This study presented the changes of disease spectrum in DPLD diagnosed by surgical lung biopsy through single center real-world data, reflecting the progress of clinicians' understanding of DPLD and interstitial pneumonia. Surgical lung biopsy is still valuable for some difficult and complicated DPLD cases.

A 52-year old man was admitted to our hospital because of dyspnea on exertion for 2 months and subcutaneous nodules for 1 month. Chest enhanced CT showed bilateral hilar and mediastinal lymphadenopathy. Bronchial alveolar lavage fluid revealed a CD4+/CD8+ T cell subsets ratio of 4.3 and culture for acid-fast bacillus (AFB) was negative. The pathology of skin nodules and transbronchial needle aspiration biopsy guided by endoscopic ultrasound (EBUS-TBNA) revealed non-caseating necrotizing epithelioid granulomas with negative acid-fast bacilli staining and periodic acid-Schiff staining, which was compatible with sarcoidosis. The patient was diagnosed as sarcoidosis and glucocorticoid was administrated. The subcutaneous nodules were improved. However, the lymph nodes were enlarged instead of shrinking after 6-month therapy. The failure to respond to glucocorticoids raised the possibility of sarcoidosis complicated with tuberculosis infection. The patient received anti-tuberculosis therapy. Lymphadenopathy responded within 4 months, and there was complete regression after 18-month treatment. The patient was followed up for 5 years and repeated chest CT scan showed that the sizes of bilateral hilar and mediastinal lymph nodes were normal.

Objective: To investigate the clinical features and long-term prognosis of patients co-existing with ovarian endometrioma (OMA) and deep infiltrating endometriosis (DIE). Methods: Totally 358 OMA patients were retrospectively analyzed, who had a minimum of 8 years follow-up after laparoscopic cystectomy, which was performed by one professional endometriosis surgery team at Peking Union Medical College Hospital from January 2009 to April 2013. All women were divided into DIE group and non-DIE group, and analysis was performed in preoperative characteristics, surgical findings and postoperative outcomes during follow-up. Results: A total of 358 OMA patients were included, of which 190 patients (53.1%, 190/358) were in the DIE group, while other 168 patients (46.9%, 168/358) in the non-DIE group. The average ages between the two groups were (33.7±5.4), (32.5±5.3) years (P=0.047), the average parity was (0.4±0.6) times vs (0.3±0.5) times (P=0.079). There were significant differences in the proportions of moderate to severe dysmenorrhea [67.4% (128/190) vs 56.5% (95/168)], chronic pelvic pain [24.2% (46/190) vs 7.7% (13/168)], and the increase in CA125 [79.9% (139/190) vs 65.2% (101/168)] between the two groups (all P<0.05). The average operation time in the DIE and non-DIE groups was (75±21) vs (39±36) minutes (P<0.01). There was a significant difference in adenomyosis presence between the two groups [41.6% (79/190) vs 22.0% (37/168); P=0.001]. All patients were followed up for at least 8 years. At the end of the follow-up, though the DIE group was with higher total rate of disease relapse, yet no significant difference was found between the two groups in statistical comparison [21.6% (41/190) vs 16.1% (27/168); P=0.185]. A total of 41 cases in the DIE group recurred, the recurrence rate of pain was 15.8% (30/190), and the recurrence rate of cyst was 8.4% (16/190); 27 cases had recurrence after operation in the non-DIE group, the recurrence rate of pain was 8.9% (15/168), and the recurrence rate of cyst was 10.7% (18/168). There were no significant differences in the pain recurrence rate (P=0.067) and cyst recurrence rate (P=0.460) between the two groups. As for the successfully pregnant patients, live birth rates were 100.0% (65/65) vs 94.4% (68/72) between DIE group and non-DIE groups (P=0.120). Conclusions: Compared with the non-DIE group, OMA patients with concurrent DIE might have severe pain symptoms, higher probability of abnormal CA125 levels and more severe pelvic adhesions. Although there are no significant differences in the total recurrence rate and the recurrence rate of various types between the two groups, the proportion of pain recurrence in the DIE group is higher than that in the non-DIE group. In terms of fertility outcomes, patients in the DIE group are with lower likelihood of pregnancy after surgery during the long-time follow-up. DIE has no significant influence on the fertility outcome.

Objective: To explore the relationship between the ideal cardiovascular health behaviors and factors and newonset heart failure. Methods: It was a prospective cohort study. People who attended the 2006-2007 physical examination of Kailuan Group Company and with complete data of cardiovascular behaviors and related factors were eligible for this study. A total of 95 167 participants who were free of valvular heart diseases, congenital heart diseases and a prior history of heart failure were included. Basic cardiovascular health score (CHS) of each participant was calculated. Participants were divided into 3 groups according to CHS. Group 1:CHS<8 (n=26 640), Group 2:8≤CHS<10 (n=35 230), Group3:CHS≥10 (n=33 297). The general clinical data and laboratory test results were collected. The outcome was defined as the first occurrence of heart failure at the end of followup(December 31, 2016). Cox regression model was used to determine the association between baseline CHS and the risk of newonset heart failure. Results: After a median followup of 10.3 years, the incidence of newonset heart failure in the group of CHS<8,8≤CHS<10,CHS≥10 were 2.7%(729/26 640), 1.8%(651/35 230) and 1.1%(360/33 297),respectively. After adjustment for age, sex, history of myocardial infarction, history of atrial fibrillation, income, alcohol consumption, education and the use of antihypertensive, cholesterol-lowering, glucose-lowering medications, compared with the group of CHS<8, the Cox regression model showed that HRs of the group of 8≤CHS<10 and CHS≥10 were 0.68 (95%CI 0.61-0.75), 0.49 (95%CI 0.43-0.55), respectively. Cox regression analysis after removing each single cardiovascular behavior or factor showed that the HR value range ability was as follows:systolic blood pressure(HR=0.78,95%CI 0.74-0.82), body mass index(HR=0.78,95%CI 0.74-0.82), fasting blood glucose (HR=0.77,95%CI 0.73-0.81), total cholesterol(HR=0.76,95%CI 0.72-0.80), physical exercise(HR=0.72,95%CI 0.69-0.76), smoking(HR=0.75,95%CI 0.71-0.79) and salt intake(HR=0.73,95%CI 0.69-0.77). Conclusion: CHS is negatively associated with the risk of newonset heart failure, and there is a dose-response relationship between the two indexes.

Objective: To investigate the characteristics and prognostic value of peripheral blood T lymphocyte subsets in patients with severe influenza. Methods: This was a single-center cross-sectional study in influenza patients admitted to Peking Union Medical College Hospital from August 2017 to April 2018. Peripheral blood lymphocyte subsets were detected by flow cytometry in both patients and 108 healthy controls. Influenza patients were divided into mild group and severe group. Severe patients were further classified into alive and fatal subgroups. Results: A total of 42 influenza patients were recruited in this study, including 24 severe cases (6 deaths). The remaining 18 cases were mild. The peripheral blood lymphocyte counts and lymphocyte subset counts (B, NK, CD4(+)T, CD8(+)T) in either mild patients[795 (571,1 007), 43 (23,144), 70 (47,135), 330 (256,457), 226 (148,366) cells/µl respectively] or severe patients[661 (474,1 151),92 (52,139), 54 (34,134), 373 (235,555), 180 (105,310) cells/µl respectively] were both significantly lower than those of healthy controls [1 963 (1 603,2 394),179 (119,239), 356 (231,496), 663 (531,824), 481 (341,693) cells/µl respectively]. Meanwhile, the T cells and CD8(+)T counts in fatal patients [370 (260,537) cells/µl and 87 (74,105) cells/µl] were significantly lower than those in severe and alive patients [722 (390,990) cells/µl and 222 (154,404) cells/µl]. CD8(+)HLA-DR/CD8(+)and CD8(+)CD38(+)/CD8(+)T cell activating subgroups in mild cases[(53.7±19.2)% and 74.8% (64.1%,83.7%) respectively] were significantly higher than those in severe cases[(38.5±21.7)% and 53.3% (45.3%,67.2%) respectively].Moreover,CD8(+)HLA-DR/CD8(+)count in severe and alive group was higher than that in fatal group [(46.1±19.1)% vs. (18.2±14.6)%, P<0.01]. Logistic regression analysis showed that CD8(+)T cell count (OR=0.952, 95%CI 0.910-0.997, P=0.035) and CD8(+)HLA-DR/CD8(+)T (OR=0.916, 95%CI 0.850-0.987, P=0.022) were both negatively correlated with mortality.Peripheral blood lymphocyte counts in mild cases rapidly decreased within 1 day after diagnosis, and returned to the basic level one week later. Conclusions: All peripheral blood lymphocyte subsets (T,B,NK) in patients with influenza are significantly reduced. These findings are consistent with the immunological characteristics of respiratory viral infections, in which peripheral lymphocytes (especially T cells) migrate to respiratory tract in the early stage and circulate to the peripheral blood after recovery. The activated CD8(+)T cell counts in peripheral blood are negatively correlated with the severity of disease, which could be considered as a prognostic indicator of severe influenza.

Objective: To investigate the clinical features and prognosis of interstitial lung disease patients with positive anti-neutrophil cytoplasmic antibody. Methods: The patients with interstitial lung disease who visited Peking Union Medical College Hospital from March 2006 to March 2016 were divided into three groups: interstitial lung disease with ANCA-positive(ANCA-ILD), connective tissue disease associated interstitial lung disease and interstitial pneumonia with autoimmune features (CTD-ILD/IPAF) and idiopathic interstitial pneumonia (IIP). The three groups were analyzed in terms of clinical manifestations, serology, lung function, imaging, survival and recurrence. Results: Two hundred and seventy four patients were enrolled and 38 (14%) were ANCA-positive of whom 16 were male and 22 were female. The age of 38 ANCA-positive patients was (59±10) years and the follow-up time was (52±31) months. Seven among the 38 ANCA-positive patients died and the death rate is 18.42%. The ANCA-positive patients with interstitial lung disease have higher onset age (ANCA-ILD:59±10,CTD-ILD/IPAF:52±10,IIP:53±11,H=19.29, P<0.001), lower hemoglobin (ANCA-ILD: 129±21, CTD-ILD/IPAF: 138±15, IIP: 140±19, H=8.17, P=0.017), higher erythrocyte sedimentation rate (ANCA-ILD:45±35, CTD-ILD/IPAF:26±24,IIP:19±22,H=19.73, P<0.001), lower lung function improvement rate after treatment (ANCA-ILD:31%,CTD-ILD/IPAF:59%,IIP: 39%,χ(2)=11.74,P=0.003), lower absorption rate of CT lesion (ANCA-ILD:61%,CTD-ILD/IPAF:82%,IIP:67%, χ(2)=9.23,P=0.010) and higher death rate(ANCA-ILD:18%,CTD-ILD/IPAF:6%,IIP:12%, χ(2)=7.16,P=0.028). Conclusions: There are significant differences in clinical characteristics between ANCA-positive patients and other types of pulmonary interstitial disease. And both the treatment effect and the prognosis is poor for the ANCA-positive patients.

Novel coronavirus pneumonia was a novel coronavirus infection that has dominated pulmonary infection since December 2019. The main manifestations were fever, dry cough, shortness of breath, normal or leukopenia in peripheral blood and changes in chest CT and in severe cases, multiple organ failure might occur. The National Health Commission, PRC has revised the consensus on diagnosis and treatment seven times in a short period of time, indicating the growing understanding of the disease. Patients with novel coronavirus pneumonia usually had history of travelling or living in the epidemic area including Wuhan within 14 days before onset, or have been exposed to patients who had fever or respiratory symptoms from the epidemic area, or had clustering diseases. However, novel coronavirus pneumonia was becoming more and more blurred after vanishing epidemic. The diagnosis and differential diagnosis of novel coronavirus pneumonia were challenges not only because of large number of tourists increasing dramatically after the relieving of epidemic, but also patients with other diseases from different areas to search for medical care. In this article, the clinical and chest imaging features of the novel coronavirus pneumonia were reviewed and compared with other infections and non-infectious diffuse pulmonary diseases. We try to find the similarities and differences among them, and to identify clues to the diagnosis of novel coronavirus pneumonia, so as to ensure accurate diagnosis and treatment.

Objective: To investigate the impact of change of ideal cardiovascular behavior and related factors on healthy vascular aging(HVA). Methods: This study was a multi-center cross-sectional survey. Six thousand three hundred and sixteen participants who underwent at least 2 healthy examinations from 2006 to 2015 at 11 hospitals, including Kailuan Hospital and so on, and examined brachial-ankle pulse wave velocity (baPWV) during 2010 and 2016, with available information about cardiovascular behavior and factors were included. The cardiovascular health score (CHS) was calculated. Basic CHS was collected from the first examination. The second CHS derived from the healthy examination in the same year of baPWV examination. Change of cardiovascular health score (ΔCHS) was calculated. Participants were defined into 5 groups according to ΔCHS, namely ΔCHS≤-2 (n=2 166), ΔCHS=-1 (n=1 284), ΔCHS=0 (n=1 187), ΔCHS=1 (n=860), and ΔCHS≥2 (n=819). Participants' characteristics, value of baPWV and proportion of HVA were compared among different groups. Multiple logistic regression analysis was used to investigate the association between ΔCHS and HVA. The ΔCHS was recalculated and included in multiple logistic regression analysis model again after each component of the cardiovascular health metrics was removed separately in order to investigate effects of removal factors on HVA by observing changes in effect values. Results: The percentage of the participants with HVA in the group of ΔCHS≤-2, ΔCHS=-1, ΔCHS=0, ΔCHS=1 and ΔCHS≥2 were 23.3%(505/2 166), 27.8%(357/1 284), 28.7%(341/1 187),31.9%(274/860) and 33.9%(278/819), respectively. After adjustment for age, sex, income, education, alcohol consumption and the basic CHS, a significant positive association between ΔCHS and proportion of participants with HVA was observed (OR=1.50, 95%CI 1.44-1.56). Multiple regression analysis after removing each single cardiovascular behavior or factor showed that the OR value decreased as follow systolic blood pressure (OR=1.04, 95%CI 1.00-1.09), fasting blood glucose (OR=1.14, 95%CI 1.09-1.18), physical exercise (OR=1.16, 95%CI 1.11-1.21), salt intake (OR=1.17, 95%CI 1.12-1.22), body mass index (OR=1.18, 95%CI 1.13-1.23), smoking(OR=1.18, 95%CI 1.13-1.23) and total cholesterol (OR=1.20, 95%CI 1.16-1.24). Conclusion: The improvement of every ideal cardiovascular behavior and factor is associated with the increase of the proportion of HVA population.
