Abstract
Objective: To describe the clinical characteristics of patients with non-small cell lung cancer (NSCLC) who developed checkpoint inhibitor pneumonitis (CIP) and to explore potential prognostic factors. Methods: NSCLC patients who were complicated with CIP after immune checkpoint inhibitors (ICIs) therapy in our institute were enrolled in this study from 1 July 2018 to 30 November 2022. Clinical data of NSCLC-CIP patients were collected, including clinical and radiological features and their outcomes. Results: Among the 70 enrolled NSCLC-CIP patients, there were 57 males (81%) and 13 females (19%). The mean age at the diagnosis of CIP was (65.2±6.3) years. There were 46 smokers (66%), 26 patients (37%) with emphysema, 19 patients (27%) with previous interstitial lung disease, and 26 patients (37%) with a history of thoracic radiation. The mean interval from the first application of checkpoint inhibitor to the onset of CIP was (122.7±106.9) days (range: 2-458 days). The main chest CT manifestations were coincided with non-specific interstitial pneumonia (NSIP) pattern and organizing pneumonia (OP) pattern. Most patients had grade 2 (21 cases) or grade 3 (34 cases) CIP. Seventeen patients had been concurrent with other immune-related adverse events such as rash, hepatitis, colitis, and thyroiditis. Half of the enrolled patients (36 patients/51%) had fever, and most patients had elevated C-reactive protein (52 patients/72%) and all patients had elevated erythrocyte sedimentation rate (70 patients/100%). Serum lactate dehydrogenase was elevated in 34 CIP patients. Prednisone≥1 mg·kg-1·d-1 (or equivalent) was the most commonly used initial treatment in CIP patients (50 patients/71.4%). Complications with pulmonary infections (OR=4.44, P=0.03), use of anti-fungal drugs (OR=5.10, P=0.03) or therapeutic dose of sulfamethoxazole (OR=4.86, P=0.04), longer duration of prednisone≥1 mg·kg-1·d-1 (or equivalent) (Z=-2.33, P=0.02) were probable potential risk factors for poor prognosis. Conclusions: Older males with smoking history might be predisposed to develop NSCLC-CIPs after ICIs therapy. NSIP pattern and OP pattern were common chest CT manifestations. Complications with pulmonary infections (especially fungal infection or Pneumocystis jirovecii pneumonia), longer duration, longer duration of high-dose corticosteroids were likely potential risk factors for poor prognosis.

Abstract
Objective: To describe the clinical characteristics of SARS-CoV-2 infected patients with interstitial lung abnormalities (ILA) during the COVID-19 pandemic. Methods: We respectively enrolled ILA patients who had been regularly followed up in Peking Union Medical College Hospital for more than six months since January 2021. Clinical data of these ILA patients were collected after the outbreak of COVID-19 pandemic (from December 2022 to January 2023), thirty-eight patients with preexisting ILA were enrolled. Among them, there were 34 ILA patients (20 males and 14 females) who were infected with SARS-CoV-2 during this period, with an average age of (64.0±8.8) years old (range: 41-80). There were 12 (35.3%) ILA patients who were suffered from COVID-19(pneumonia group) and others were the non-pneumonia group. The clinical characteristics, including vaccination status, features of COVID-19 and outcomes of the two groups were compared. Results: Regarding the subcategories of ILA, there were 7 cases of subpleural fibrotic ILA, 10 cases of subpleural non-fibrotic ILA, and 17 cases of non-subpleural ILA. Before SARS-CoV-2 infection, the average pulse oxygen saturation at rest was (97.38±0.87)% (range: 96%-99%); average forced vital capacity (FVC) was (97.6±18.1)% predicted (range: 65%-132%); and average diffusion capacity for carbon monoxide (DLCO) was (76.2±16.3)% predicted (range: 53%-108%). Nineteen patients had been vaccinated with 3 doses of SARS-CoV-2 vaccines, and 5 of them developed COVID-19. One patient had received one dose of vaccine and did not develop COVID-19. The other 14 patients had not been vaccinated, and seven of them developed COVID-19. Of the 12 patients with COVID-19, six were diagnosed with severe COVID-19, and the other 6 ILA patients were diagnosed with moderate COVID-19. Among them, 1 patient was complicated by deep vein thrombosis of left lower limb. All 6 patients with severe COVID-19 who were cured after systemic corticosteroids. As for the other six moderate COVID-19 patients, all were cured and/or improved greatly: two were treated with short-term oral corticosteroids, one was prescribed a dose of compound betamethasone, and the other two were not treated with systemic corticosteroids. Conclusion: Patients with ILA were predisposed to develop COVID-19 after infection with SARS-CoV-2, and more than half of them had severe COVID-19.

Abstract
Objective: To evaluate the efficacy of the Hodgkin lymphoma (HL)-2013 regimen in the treatment of children with HL, and to investigate the prognostic factors of childhood HL. Methods: Clinical data of 145 children (aged ≤18 years) with newly diagnosed HL, treated with HL-2013 regimen in 8 tertiary referral centers for childhood cancer from August 2011 to April 2021 were analyzed retrospectively. All the diagnosis were confirmed by histopathological morphology and immunohistochemical examination. The clinical characteristics and treatment outcomes were summarized, and the patients were divided into different groups according to clinical characteristics. Kaplan-Meier method was used for survival analysis, and the comparison of survival rates between groups was performed with Log-rank test. Results: Of the 145 cases, there were 115 males and 30 females, the age at diagnosis was 7.9 (5.8, 10.6) years. Cervical lymph node enlargement (114 cases, 78.6%) was the common symptom of the disease, and 57 patients (39.3%) were accompanied by large masses. The most common pathological classification was mixed cell type (93 cases, 64.1%). According to the Ann Arbor staging system, there were 9 cases of stage Ⅰ, 62 cases of stage Ⅱ, 45 cases of stage Ⅲ, 29 cases of stage Ⅳ. According to the risk stratification: there were 14 cases of low-risk group, 76 cases of medium-risk group and 55 cases of high-risk group. Of all patients, 68 cases (46.9%) achieved an early complete remission (CR) after 2 courses of chemotherapy, and the CR rate was 93.8% (136/145) after first-line treatment. Disease recurrence or progression occurred in 22 cases (15.2%). Of all patients, 125 cases survived, 6 cases died and 14 cases were lost to follow-up. Among the survived cases, 123 cases were continuously at CR state,and the follow-up time was 55 (40, 76) months. The 5-year overall survival (OS) and event free survival (EFS) rates were (95.3±1.9)% and (84.2±3.0)% for the entire group, respectively. 5-year OS and EFS rates for patients with stage Ⅲ-Ⅳ were both lower than those for patients with stage Ⅰ-Ⅱ (χ2=6.28 and 7.58, both P<0.05), the 5-year OS and EFS rates for patients in high-risk group were both lower than those for patients in low-risk and medium-risk group (χ2=10.93, 7.79, both P<0.05). The 5-year OS rates for the patient with early CR and without early CR were 100.0% and (90.9±3.6)% (χ2=5.77, P=0.016). EFS rates for the patient with early CR (68 cases) and without early CR (77 cases) were (93.8±3.0)% and (75.8±5.0)% (χ2=8.78, P=0.003). Conclusions: HL-2013 regimen is significantly effective in the treatment of pediatric HL. However, the patients in high-risk group and those without early CR are prone to disease recurrence or progression. Stage Ⅲ-Ⅳ and without early CR were associated with worse prognosis.

Abstract
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.

Abstract
Cystic echinococcosis of the abdominal wall is relatively rare. Here, a 54-year-old patient with cystic echinococcosis of the abdominal wall was reported, who was admitted to hospital due to presence of abdominal mass for one year complicated by skin ulceration of the mass for 5 days. The case was initially diagnosed as cystic echinococcosis of the abdominal wall and given sub-abdominal echinococcosis cystectomy. Post-surgical pathological examinations revealed cystic echinococcosis (type of a single locule and multiple daughter cysts). This case report aimed to provide insights into the clinical diagnosis and treatment of cystic echinococcosis of the abdominal wall.

Abstract
Objective: To investigate the long-term incidence of coronary events and related factors in patients undergoing cardiac thoracotomy without preoperative coronary angiography (CAG). Methods: This was a retrospective study. The clinical data of patients, aged between 40 and 49 years old, who underwent cardiothoracic surgery, including heart valve surgery, congenital heart disease surgery, cardio great vessels surgery and other non-coronary artery disease (CAD) surgery, in Nanjing Drum Tower Hospital from December 2009 to May 2017, were enrolled. Patients with suspected CAD, or patients with coronary CTA defined calcified coronary arteries received CAG examination prior operation, and the rest patients did not receive routine CAG examinations. The patients who did not receive routine CAG examinations were followed up by telephone. The primary endpoints include death related to coronary arteries, coronary artery bypass graft (CABG) or percutaneous coronary intervention (PCI). The secondary endpoints include the new onset angina, clinically diagnosed CAD or receiving the first and second prevention for CAD. The other outcome events included cardiac death and all-cause mortality. The primary and secondary endpoints were all regarded as coronary events. The patients without preoperative CAG were divided into two groups: the positive group and the negative group, according to the incidence of coronary events during follow-up. Clinical data were compared between the two groups. Results: A total of 952 patients were included. The age was (45.2±2.7) years old, 406(42.65%) patients were male. Preoperative CAG was performed in 73 patients, among whom 9 (12.32%) patients underwent simultaneous CABG. Among the 879 cases who did not undergo coronary angiography before the operation, 18(2.05%) died during perioperative period (hospitalization and within 30 days after discharge). The patients were followed up for (61.6±25.8) months, and 28(3.25%) patients were lost to follow up. During long-term follow up, there were no fatal cases due to severe coronary events and no cases of CABG or PCI. Only 4.41% (38/861) patients had the secondary endpoints, namely the occasional onset of atypical angina. The incidence rate of the long-term coronary events, all-cause mortality and cardiac death were 4.41% (38/861), 1.16% (10/861), 0.46% (4/861) during long-term follow-up. The prevalence of hypertension was significantly higher in positive group than negative group (34.21% (13/38) vs. 20.89% (164/785), P=0.045). Conclusions: It is feasible not to perform preoperative CAG examination for non-CAD patients aged 40-49 years who will undergo cardiac thoracotomy. However, we need to be aware the risk of coronary events in the patients complicating with risk factors of CAD, such as hypertension.

Abstract
Objectives: To describe the clinical features and prognosis of pulmonary actinomycosis in a tertiary Chinese hospital. Methods: We conducted a retrospective analysis of 32 patients diagnosed with pulmonary actinomycosis between January 2013 and December 2019. General characteristics, clinical manifestations, lab data, chest CT imaging, treatment and follow-up information were reviewed and analyzed. Results: This study consisted of 19 males and 13 females, with a mean age of (58±12) years, ranging from 16 to 76 years. There were 26 cases with co-morbidities. Among them, there were 16 cases with pulmonary co-morbidity. Sixteen cases had a smoking history. Eight cases, 5 men and 3 women, with a mean age of (48±8) years, ranging from 41 to 58 years, received thoracic surgery for diagnosis. The remaining 24 cases who did not receive thoracic surgery consisted of 14 males and 8 females, with a mean age of (54±14)years, ranging from 16 to 76 years. Cough (25cases), expectoration (21 cases) and fever (16 cases) were the common clinical manifestations. The erythrocyte sedimentation rate (ESR) ranged from 2 to 114 mm/1 h, with a mean value of (28±31) mm/1 h. The ESR was elevated (>20 mm/1 h) in 15 cases. The C-reactive protein (CRP) ranged from 1 to 116 mg/L, with a mean value of (28±45) mg/L. The CRP was elevated (>8 mg/L) in 16 cases. Localized air-space consolidation (18 cases), pulmonary mass or nodules (16 cases) were the common chest CT manifestations. When compared with non-surgical cases, fever was the sole characteristic that was less common in cases with thoracic surgery (1 case in surgical group vs 11 cases in non-surgical group, P<0.05). Actinomyces spp. was found in 7 cases (87.5%) who received thoracic surgery, in 16 (61.5%) specimens collected through bronchoscopy and in 10 (55.6%) sputum samples of good quality. All of our enrolled cases were administrated with oral antibiotics, and 14 cases were prescribed with intravenous antibiotics initially. Among them, 27 cases were administrated with more than one antibiotic. Penicillin, ampicillin and amoxillin were prescribed for 25 cases. Finally, 30 cases showed improvement or cure in our hospital. Conclusions: Pulmonary actinomycosis tended to develop in aged patients with co-morbidities. Cough, expectoration, fever and localized air-space consolidation were the common clinical and radiological manifestations, respectively. Actinomyces spp. could be found more easily in the surgically resected tissues than other specimens. The prognosis of our enrolled cases was good after treatment with combined antibiotics.

Abstract
Coronavirus disease 2019 (COVID-19) can cause great damage to the elderly patients and lead to high mortality. The clinical presentations and auxiliary examinations of the elderly patients with COVID-19 are atypical, due to the physiological ageing deterioration and basal pathological state. The treatment strategy for the elderly patients has its own characteristics and treatment protocol should be considered accordingly. To improve the diagnosis, treatment, and prevention of COVID-19 in the elderly, the Expert Committee of Geriatric Respiratory and Critical Care Medicine, China Society of Geriatrics established the "Expert consensus for the diagnosis, treatment, and prevention of Coronavirus disease 2019 in the elderly" . We focused on the clinical characteristics and key points for better treatment and prevention of COVID-19 in the elderly. (1) For diagnosis, atypical clinical presentation of COVID-19 in the elderly should be emphasized, which may be complicated by underlying disease. (2) For treatment, strategy of multiple disciplinary team (mainly the respiratory and critical care medicine) should be adopted and multiple systemic functions should be considered. (3) For prevention, health care model about integrated management of acute and chronic diseases, in and out of hospital should be applied.

Abstract
Objective: To analyze the clinical features and the results of the whole exome sequencing (WES) of a Chinese family containing both pulmonary sarcoidosis patients and healthy members, and to find potent genes and variants that may be involved in the pathogenesis of sarcoidosis. Methods: Three patients with pulmonary sarcoidosis and 1 healthy member was included from a Chinese Han family in the north of China diagnosed in November 2016, which characterized as 2 consecutive generations including 2 males and 1 female, aged from 23 to 69 years old. The proband is Ⅱ-6. Pulmonary sarcoidosis was diagnosed by clinical features, imaging and pathological findings, and clinical data such as family history were collected. Whole blood samples were taken and WES (Illumina NovaSeq S2) was performed. The pathogenicity analysis and gene annotation analysis were performed by ExAC, SIFT, Polyphenv2, Metascape databases. Results: It was found that 27 genes were highly pathogenic in the database filtering result. After gene annotation analysis, we found that ZC3H12A gene can negatively regulate the differentiation of Th17 cells, which may be involved in the onset of pulmonary sarcoidosis. Sanger sequencing confirmed the c.1361 A>G variant in 3 sarcoidosis patients but normal in healthy member. Conclusions: In patients with familial pulmonary sarcoidosis, the genetic background could regulate immune response which is one of the pathogenic mechanisms of sarcoidosis. The whole exome test and gene ontology analysis showed that Ⅱ-2, Ⅱ-6 and Ⅲ-1 pulmonary sarcoidosis patients in this family were all shared the same variant on ZC3H12A gene, which played a pivotal role in differentiation of Th17 cells and is a potent pathogenesis gene in this Chinese pulmonary sarcoidosis family.

Abstract
Using angle resolved photoemission spectroscopy measurements of Bi2Sr2CaCu2O8+δ over a wide range of doping levels, we present a universal form for the non-Fermi liquid electronic interactions in the nodal direction in the exotic normal state phase. It is described by a continuously varying power law exponent versus energy and temperature (hence named a Power Law Liquid or PLL), which with doping varies smoothly from a quadratic Fermi Liquid in the overdoped regime, to a linear Marginal Fermi Liquid at optimal doping, to a non-quasiparticle non-Fermi Liquid in the underdoped regime. The coupling strength is essentially constant across all regimes and is consistent with Planckian dissipation. Using the extracted PLL parameters we reproduce the experimental optics and resistivity over a wide range of doping and normal-state temperature values, including the T* pseudogap temperature scale observed in the resistivity curves. This breaks the direct link to the pseudogapping of antinodal spectral weight observed at similar temperature scales and gives an alternative direction for searches of the microscopic mechanism. The normal state of hole-doped, high-temperature superconductors is a currently-unexplained "strange metal" with exotic electronic behaviour. Here, the authors show that a doping-dependent power law ansatz for the electronic scattering phenomenologically captures ARPES, transport and optics observations.

Abstract
Objective: To explore the effect of pirfenidone in fibrotic interstitial pneumonia with autoimmune features (IPAF) after treatment with corticosteroids and immunosuppressants. Methods: We conducted a retrospective analysis of 2 adult patients with IPAF in the Peking Union Medical College Hospital. As their fibrotic interstitial lung disease failed to improve with further treatment with corticosteroids and immunosuppressants, they were treated with pirfenidone based on corticosteroids and immunosuppressants. Their clinical, chest radiological data and prognosis were collected and relevant literatures were reviewed. Results: One patient was a 43 year old female, the other was a 53 year old male. IPAF was diagnosed with their classic clinical, serological and radiological features. They were partially responded to corticosteroids and immunosuppressants at the initial period. Pirfenidone was suggested for them as their lung fibrosis was not improved further with immunosuppressive therapy. After 4-5 months treatment with pirfenidone, based on corticosteroids and immunosuppressant administration, their clinical and radiological manifestations improved significantly. Conclusions: Pirfenidone might be a good add-on choice for fibrotic IPAF when the disease did not respond well to corticosteroids and immunosuppressants.

Abstract
Objective: To explore the role of histone deacetylases(HDAC) in the pathogenesis of idiopathic pulmonary fibrosis(IPF) and cryptogenic organizing pneumonia(COP). Methods: Fifteen IPF patients [14 males and 1female, age 40-73 years, mean age (59±8) years] and 15 COP patients [5 males and 10 females, age 41-71 years, mean age (59±8) years] from Peking Union Medical College Hospital were recruited from March 2018 to October 2018. Fifteen healthy donors[4 males and 11females, age 43-70 years, mean age (58±6) years] were enrolled as controls. Peripheral blood mononuclear cells (PBMC) were isolated by density gradient centrifugation. The nuclear and cytoplasmic proteins were extracted by Nuclear Extraction Kit. HDAC activity was measured by fluorimetric method. The relations between HDAC activity and clinical parameters were analyzed with SPSS. Results: The HDAC activity of cytoplasmic protein and nuclear protein from patients with IPF were (724±216) nmol/L and (2 309±708) nmol/L, which were higher than that of health controls (409±105) nmol/L and (1 572±611) nmol/L (P<0.01 for both). So as to the HDAC activity of cytoplasmic protein and nuclear protein from patients with COP which were (718±245) nmol/L and (3 310±1 005) nmol/L (P<0.01 for both).The HDAC activity of nuclear protein from COP patients was higher than that from IPF patients (Z=-2.840, P=0.005). The HDAC activity of nuclear protein was negatively correlated with FEV(1) and D(L)CO in IPF patients (r=-0.574, P=0.025; r=-0.583, P=0.029), and negatively correlated with FVC and TLC in COP patients(r=-0.846, P=0.016; r=-0.900, P=0.015). Conclusion: HDAC may be involved in the pathogenesis of COP and IPF.

Abstract
Objective: To explore the differential diagnostic role of B cell-activating factor(BAFF) in idiopathic pulmonary fibrosis (IPF) and usual interstitial pneumonia (UIP) associated with autoimmune diseases (AIDs). Methods: Plasma levels of BAFF were measured by ELISA method in 23 patients with AIDs-UIP, 34 patients with IPF, and 21 healthy subjects as control. The correlation between plasma BAFF levels and other clinical results from patients was analyzed. Receiver operating characteristics (ROC) analysis for distinguishing AIDs-UIP from IPF patients was examined and the maximal area under curve (AUC) was found. Results: Plasma levels of BAFF were significantly elevated in AIDs-UIP patients and IPF patients compared to healthy subjects(P<0.001 and P=0.002, respectively). AIDs-UIP patients had higher level of BAFF than IPF patients(P=0.030). Plasma BAFF levels in AIDs-UIP patients were inversely correlated with pulmonary function results, including FVC%(r=-0.435, P=0.040)and TLC%(r=-0.449, P=0.041), as well as DLCO%(r=-0.491, P=0.024). When the cut off value of BAFF was set as 1.5 ng/ml to distinguish AIDs-UIP patients from IPF patients, the sensitivity and the specificity was 64.5% and 90.0%, respectively, and the area under ROC curve reached the maximum of 0.784(P=0.000, 95% CI: 66.3%-90.5%). Conclusions: Plasma BAFF levels were significantly higher and inversely correlated with pulmonary function, reflecting the severity of AIDs-UIP patients. Plasma BAFF levels may be a useful marker for distinguishing AIDs-UIP from IPF.

Abstract
Objective: To investigate the related risk factors for hemorrhagic transformation (HT) of cerebellar infarction after posterior fossa decompression surgery. Methods: A total of 91 patients with cerebellar infarction were treated by posterior fossa decompression surgery in Department of Neurosurgery of Jinhua Municipal Central Hospital from Jan 2010 to Jan 2018, were selected as study subjects. The HT group included 17 cases, while the Non-HT group included 74 cases. The clinical data of the two groups were analyzed retrospectively, the univariate and non-conditional lgistic regression analysis were performed to detect the relevant risk factors for hemorrhagic transformation of cerebellar infarction after posterior fossa decompression surgery. Results: By univariate analysis, the differences of these seven risk factors, the large area cerebellar infarction (the diameter of area was larger than 5 cm), pre-op thrombolysis, pre-op mild HT, oral anticoagulants, atrial fibrillation, hyperglycemia and fluctuation of BP in post-op, between two groups were statistically significant (P<0.05). By multivariate logistic analysis, the large area cerebellar infarction (P<0.05), pre-op thrombolysis(P<0.01), pre-op mild HT (P<0.01), oral anticoagulants (P<0.01) were the independent risk factors for post-op HT. Conclusions: The large area cerebellar infarction (the diameter of area was more than 5 cm), pre-op thrombolysis, pre-op mild HT, oral anticoagulants, atrial fibrillation, hyperglycemia and fluctuation of BP in post-op are important risk factors for post-op HT. The large area cerebellar infarction, pre-op thrombolysis, pre-op mild HT, oral anticoagulants are the independent risk factors for post-op HT. A proper pre-op evaluation of these risk factors and an individualized treatment for post-op HT would help a lot with balancing operational risk and improving prognosis.

Abstract
Objective: To describe the clinical characteristics of respiratory manifestations of yellow nail syndrome. Methods: We conducted a retrospective analysis of 2 patients with respiratory diseases associated with yellow nail syndrome. Their clinical and chest radiological data were collected. We searched PubMed, Wanfang and CNKI databases with the keywords "yellow nail syndrome, yellow nail and lung" in Chinese and English. And the relevant literatures, including 6 articles in Chinese and 81 articles in English, were reviewed. Results: Our 2 patients were male, one 60 years old and the other 76. Typical yellow nails were present in their fingers, and one of them also showed toe yellow nails. One patient was admitted for refractory respiratory infection and he was diagnosed with diffuse bronchiectasis. The respiratory symptoms could be relieved with antibiotics according to the results of sputum microbiological analysis. The other patient was admitted for cough and exertional dyspnea, and refractory pleural effusions were revealed bilaterally. He received repeated effusion drainage by thoracentesis, and Octreotide was tried recently. A total of 373 cases were reviewed in Chinese and English literatures. Pleural effusions (152 cases) and diffuse bronchiectasis (121 cases) were the most common reported respiratory manifestations. Lymphoedema was present in almost all cases with pleural effusion associated with yellow nail syndrome, and the effusion was usually exudative and lymphocyte predominant. Pleurodesis and decortication were effective for them. But, somatostatin analogues had been tried effectively for these patients recently. On the other hand, literatures showed that diffuse bronchiectasis in yellow nail syndrome was less severe than idiopathic diffuse bronchiectasis, and might benefit from long-term macrolide antibiotics. Conclusions: Yellow nail syndrome is a very rare disorder. Besides yellow nail, respiratory manifestations are the main clinical presentations. Diffuse bronchiectasis and recurrent pleural effusions are the common manifestations.

Abstract
Objective: To investigate the expression of interleukin(IL)-35 protein and gene in peripheral blood of patients with sarcoidosis and its clinical significance. Methods: Peripheral blood samples from 98 patients with sarcoidosis and 98 healthy volunteers were collected at Peking Union Medical College Hospital between January 2016 and March 2017. The plasma levels of IL-35 were detected by enzyme-linked immunosorbent assays (ELISA), and the relationship between IL-35 and the clinical characteristics was analyzed. Real-time quantitative PCR was used to detect the expression levels of IL-35 subunit EBI3, p35 and T regulatory cell transcription factor Foxp3 mRNA in peripheral blood mononuclear cells, and their correlations were analyzed. Results: The plasma levels of IL-35 in patients with sarcoidosis (44±12) ng/L was significantly lower than that in the normal control group (55±12) ng/L (P<0.001). There was a positive correlation between the plasma levels of IL-35 and D(L)CO% predicted values (r=0.76, P<0.001), but it showed no significantly correlation with other clinical parameters. The expression of EBI3 and Foxp3 mRNA in peripheral blood mononuclear cells of patients with sarcoidosis (1.54±0.74, 0.92±0.36) were significantly lower than those in the normal control group respectively (2.12±0.61, 1.10±0.27, all P<0.05). There was a significant positive correlation between the expression of EBI3 and Foxp3 mRNA in the sarcoidosis group (r=0.786, P<0.001). Conclusion: IL-35 may be involved in the inflammatory process of sarcoidosis and play an important role in the pathogenesis of the disease.

Abstract
Objective: To describe the clinical and radiological characteristics of antisynthetase syndrome associated interstitial lung disease in patients with different serum anti-aminoacyl-tRNA synthetase antibodies. Methods: We conducted a retrospective analysis of 5 adult patients with antisynthetase syndrome associated interstitial lung disease in Peking Union Medical College Hospital. Their clinical and chest radiological data were analyzed and relevant literatures were reviewed. Results: Among these 5 patients, there were 1 male and 4 females, aged from 32 y to 67 y, with a mean age of 53 y. Cough and exertional dyspnea were the main clinical complaints. Four cases showed mechanic's-like hands, and all of the 5 cases had Velcro rales in the basal lungs. None of them showed clubbing. Creatine kinase was elevated in 1 case with anti-Jo-1 synthetase antibody, and anti-nuclear antibody was positive in 4 cases, with different titers from 1∶80 to 1∶320, and anti-Ro-52 antibody was positive in 3 cases. Anti-aminoacyl-tRNA synthetase antibody spectrum analysis showed 1 case with anti-Jo-1, 1 anti-PL-7, 1 anti PL-12, 1 anti-EJ and 1 anti-OJ synthetase antibody, respectively. Chest high resolution CT showed nonspecific interstitial pneumonia pattern in 1 case, and nonspecific interstitial pneumonia pattern with organizing pneumonia pattern in 4 cases. All the cases responded to immunosuppressive therapy including corticosteroids (with starting prednisone dosage more than 1 mg·kg(-1)·d(-1)) plus azathioprine or Mycophenolate mofetil. Conclusions: Antisynthetase syndrome associated interstitial lung disease, characterized by the presence of different anti-tRNA synthetase antibodies, is an increasingly recognized clinical entity. Clinical and radiological features of different subtypes of antisynthetase syndrome are relatively heterogeneous. Nonspecific interstitial pneumonia pattern, nonspecific interstitial pneumonia pattern with organizing pneumonia pattern and organizing pneumonia pattern were common chest HRCT patterns. Prednisone plus immunosuppressive agents are the recommended first line therapy.

Abstract
Anti-opium-smoking had been the key policy of successive central and local governments from the late Qing Dynasty to the Republican Period. Since the establishment of the Nanjing Provisional Government in January 1912, the Anti-opium-smoking campaign had culminated across the country. Under the support of the government, the "National Anti-Opium Association of China" and "Association of Chinese People Rejecting Opium" were established which made an important contribution to China's anti-opium-smoking campaign.Yunnan, Shaanxi, Heilongjiang, Zhejiang, Shanghai and other local governments also combined with local specific circumstances to make anti-opium-smaking policy for punishing severely the opium cultivation, trade and opium smoking, thus, the overrun of opium began to be brought under an overall control.

Abstract
Objective:Evaluate the application value of modified rhytidectomy incision in superficial parotid gland tumor resection.Method:Seventy-one patients with tumor in the superficial parotid were included in this study from January 2012 to January 2015. They all accepted superficial parotidectomy or subtotal superficial parotidectomy. Thirty-six cases used modified rhytidectomy incision and 35 cases used modified blair incision. The data of operative field exposure, operating time, bleeding, the rate of complication, score of patients's satisfaction were recorded and compared between the two groups.Result:There was no statistically significant difference between the two groups in the operative field exposure, operating time and bleeding (P > 0.05). No difference was found between the two groups in the rate of facioplegia, while the rate of insensible earlobe in the modified rhytidectomy incision group was significantly lower than the modified blair incision group (P < 0.05). The score of patient's satisfaction in the modified rhytidectomy incision group was significantly higher than the other group (P < 0.05).Conclusion:The modified rhytidectomy incision provides good exposure and has the advantage of less complication and better cosmetic outcome. It is worthy of wide clinical application.

The differences in success rate and detecting parameters between FS and FT were analyzed, as well as the correlation between FS and FT values. The t-test was used for comparison of normally distributed continuous data between groups, and a one-way analysis of variance or the Kruskal-Wallis test was used for comparison between multiple groups. The Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups. Results: A total of 1621 patients were enrolled. The success rates of FT and FS were 100% and 94.96%, respectively, and the success rate of FS was influenced by sex, age, body mass index, and biochemical markers of liver function. FT has a significantly shorter duration of single detection and a significantly lower number of times of single detection than FS(duration of single detection: 190.21±38.78 s vs 220.89±68.36 s, P < 0.01; number of single detection times: 10.31±1.32 vs 11.81±3.76, P < 0.01), as well as a significantly lower ratio of interquartile range to median of fat quantification in the same patient(5.39%±4.81% vs 17.18%±14.07%, P < 0.01). The LSM and fat quantification of FS were significantly correlated with those of FT(r = 0.645 and 0.620, both Based on the duration and number of times of single detection, success rate, and stability of fat quantification, FT seems to have a better detection efficiency than FS. The detection values of FT and FS can be calculated with regression equations < 0.01). The equations of linear regression were LSM(FT)= 4.435+0.477×LSM(FS); CAP(FT)= 134.71+0.456×CAP(FS). Conclusion: Based on the duration and number of times of single detection, success rate, and stability of fat quantification, FT seems to have a better detection efficiency than FS. The detection values of FT and FS can be calculated with regression equations.

Abstract
Objective: To explore the plasma chemokines expressions and related clinical implication in patients with Stanford type A aortic dissection (AD). Methods: We retrospectively analyzed the data of 65 patients with Stanford type A aortic dissection, hypertensive patients and 11 healthy subjects admitted in our department from October 2013 to December 2014, they were divided into four groups: NH-CON group (11 healthy subjects), H-AD group (29 AD patients with hypertension), NH-AD group (21 AD patients without hypertension), and H-CON group (14 hypertension patients). Four plasma samples from AD patients and 4 plasma samples from healthy subjects were collected randomly with random numbers table, and the levels of different chemokines were examined by protein array analysis. Then, plasma levels of chemokines including macrophage inflammatory protein 1β(MIP-1β), epithelial neutrophil activating peptide 78(ENA-78), interleukin 16(IL-16), interferon inducible protein 10(IP-10) and FMS-like tyrosine kinase 3(Flt-3) ligand were analyzed by luminex. Pearson analysis was used to determine the correlations between the chemokines and serum C reactive protein (CRP) levels. Results: Plasma levels of MIP-1β(34.0(29.3, 47.2) ng/L vs. 51.0(28.2, 80.7) ng/L, P<0.05) and ENA-78(110.5(59.1, 161.4) ng/L vs. 475.7(299.3, 837.3) ng/L, P<0.05) were significantly lower in H-AD group, while plasma IL-16 level was significantly higher in H-AD group(54.7(16.3, 187.8) ng/L vs. 17.5(11.9, 20.8) ng/L, P<0.05) than in H-CON group. Plasma levels of MIP-1β(48.3(26.4, 62.1) ng/L, P<0.05) were significantly lower in H-AD patients than in NH-AD patients. Plasma level of ENA-78 was significantly lower in NH-AD group than in NH-CON group (95.0(58.0, 155.0) ng/L vs. 257.7(85.2, 397.8) ng/L, P<0.05). The levels of IP-10 and Flt-3 ligand were similar among the 4 groups (all P>0.05). Pearson analysis showed that there were no correlation between MIP-1β(r(2)=0.01, P>0.05), ENA-78(r(2)=0.02, P>0.05), IL-16(r(2)=0.02, P>0.05), IP-10(r(2)=0.00, P>0.05), Flt-3 ligand(r(2)=0.02, P>0.05) and CRP levels in patients with Stanford type A aortic dissection. Conclusions: Lower plasma levels of MIP-1β and ENA-78 and higher plasma levels of IL-16 may associate with the occurrence and development of type A aortic dissection, but their concentrations are not correlated with serum CRP levels. There is no significant change on plasma levels of IP-10 and Flt-3 in the Stanford type A aortic dissection patients.

Abstract
The development of environmentally benign catalysts for highly enantioselective asymmetric cis-dihydroxylation (AD) of alkenes with broad substrate scope remains a challenge. By employing [Fe(II) (L)(OTf)2 ] (L=N,N'-dimethyl-N,N'-bis(2-methyl-8-quinolyl)-cyclohexane-1,2-diamine) as a catalyst, cis-diols in up to 99.8 % ee with 85 % isolated yield have been achieved in AD of alkenes with H2 O2 as an oxidant and alkenes in a limiting amount. This "[Fe(II) (L)(OTf)2 ]+H2 O2 " method is applicable to both (E)-alkenes and terminal alkenes (24 examples >80 % ee, up to 1 g scale). Mechanistic studies, including (18) O-labeling, UV/Vis, EPR, ESI-MS analyses, and DFT calculations lend evidence for the involvement of chiral Fe(III) -OOH active species in enantioselective formation of the two C-O bonds.

Abstract
OBJECTIVE To study the role of esophagogastric junction contractile index (EGJ-CI) in evaluating the function of anti-reflux barrier, and in differentiating patients with gastroesophageal reflux disease (GERD) from those with functional heartburn (FH). METHODS A total of 115 patients presenting heartburn were enrolled in the study from January 2012 to June 2015.All subjects had completed Gerd-Q questionnaire and undergone gastroscopy, 24-hour pH-impedance monitoring and esophageal high-resolution manometry. GERD patients were divided into as reflux esophagitis, acid-nonerosive reflux disease (NERD) and weakly acid-NERD groups. Patients with normal esophageal mucosa, normal acid exposure and negative proton pump inhibitor test were enrolled in FH group. EGJ-CI (mmHg·cm) as well as EGJ rest pressure and 4s integrated relaxation pressure (IRP 4s) were measured. RESULTS Among the 115 patients, 18 were reflux esophagitis [(49.0±18.9) years, M∶F=10∶8], 25 were acid-NERD [(48.7±14.4) years, M∶F=13∶12], 37 were weakly acid-NERD [(52.0±14.8) years, M∶F=15∶22] and 35 were FH [(53.6±14.8), M∶F=8∶27]. No differences of Gerd-Q scores were noticed between the four groups. (1)Negative correlations were demonstrated between EGJ-CI and esophageal acid exposure time (r=-0.283, P=0.002), EGJ-CI and acid reflux events (r=-0.233, P=0.012), EGJ-CI and weakly acid reflux events (r=-0.213, P=0.022), EGJ-CI and non-acid reflux events (r=-0.200, P=0.032). (2)The value of EGJ-CI was significantly higher in FH patients than in the three subgroups of GERD(all P<0.01). EGJ rest pressure of FH group was higher than that of acid-NERD (P<0.01). IRP 4s in acid-NERD group was lower than that of FH and weakly acid-NERD (P<0.05). (3)The area under curve (AUC) of EGJ-CI was higher than that of EGJ-CIT, EGJ rest pressure or IRP 4s(0.686 vs 0.678, 0.641 and 0.578). The cut-off value of EGJ-CI to differentiate GERD from FH was 9.74 mmHg·cm with sensitivity 82.86% and specificity 51.52%. CONCLUSIONS The EGJ-CI values are negatively correlated with esophageal acid exposure time, weakly acid reflux events and non-acid reflux events. Thus it might be used as a metric to reflect the anti-reflux function of EGJ. According to the cut-off value of EGJ-CI 9.74 mmHg·cm, patients with GERD can be sensitively differentiated from patients with FH.

Abstract
Graphene has attracted increasing interest due to its remarkable properties. However, the zero band gap of monolayered graphene limits it's further electronic and optoelectronic applications. Herein, we have synthesized monolayered silicon-doped graphene (SiG) with large surface area using a chemical vapor deposition method. Raman and X-ray photoelectron spectroscopy measurements demonstrate that the silicon atoms are doped into graphene lattice at a doping level of 2.7-4.5 at%. Electrical measurements based on a field effect transistor indicate that the band gap of graphene has been opened via silicon doping without a clear degradation in carrier mobility, and the work function of SiG, deduced from ultraviolet photoelectron spectroscopy, was 0.13-0.25 eV larger than that of graphene. Moreover, when compared with the graphene/GaAs heterostructure, SiG/GaAs exhibits an enhanced performance. The performance of 3.4% silicon doped SiG/GaAs solar cell has been improved by 33.7% on average, which was attributed to the increased barrier height and improved interface quality. Our results suggest that silicon doping can effectively engineer the band gap of monolayered graphene and SiG has great potential in optoelectronic device applications.

Abstract
This paper presents an extensive numerical analysis of a high-contrast grating VCSEL emitting at 0.98 μm. Using a three-dimensional, fully vectorial optical model, we investigate the influence of a non-uniform grating with a broad range of geometrical parameters on the modal behavior of the VCSEL. Properly designed and optimized, the high-contrast grating confines the fundamental mode selectively in all three dimensions and discriminates all higher order modes by expelling them from its central region. This mechanism makes single mode operation possible under a broad range of currents and could potentially enhance the single-mode output power of such devices. The high-contrast grating design proposed here is the only design for a VCSEL with three-dimensional, selective, optical confinement that requires relatively simple fabrication.

Abstract
We report femtosecond resonant soft x-ray diffraction measurements of the dynamics of the charge order and of the crystal lattice in nonsuperconducting, stripe-ordered La1.875Ba0.125CuO4. Excitation of the in-plane Cu-O stretching phonon with a midinfrared pulse has been previously shown to induce a transient superconducting state in the closely related compound La1.675Eu0.2Sr0.125CuO4. In La1.875Ba0.125CuO4, we find that the charge stripe order melts promptly on a subpicosecond time scale. Surprisingly, the low temperature tetragonal (LTT) distortion is only weakly reduced, reacting on significantly longer time scales that do not correlate with light-induced superconductivity. This experiment suggests that charge modulations alone, and not the LTT distortion, prevent superconductivity in equilibrium.

Abstract
We use angle-resolved photoemission spectroscopy and a new quantitative approach based on the partial density of states to study properties of seemingly disconnected portions of the Fermi surface (FS) that are present in the pseudogap state of cuprates called Fermi arcs. We find that the normal state FS collapses very abruptly into Fermi arcs at the pseudogap temperature (T*). Surprisingly, the length of the Fermi arcs remains constant over an extended temperature range between T* and T(pair), consistent with the presence of an ordered state below T*. These arcs collapse again at the temperature below which pair formation occurs (T(pair)) either to a point or a very short arc, whose length is limited by our experimental resolution. The tips of the arcs span between points defining a set of wave vectors in momentum space, which are the fingerprints of the ordered state that causes the pseudogap.
