摘要： Gastroesophageal reflux disease (GERD) was diagnosed and fundoplication was performed, which relieved the symptoms. This paper explores the effect of fundoplication on GERD-related respiratory symptoms. From January 2007 to October 2008, 64 patients with respiratory symptoms related to GERD were consecutively enrolled for laparoscopic fundoplication. Of these, 60 patients had respiratory symptoms mainly combined with gastroesophageal reflux, while four had respiratory symptoms only. All patients had GERD confirmed, and medical treatment provided before surgery resulted in an insufficiently favorable effect or even producing further complications. All the patients were requested to fill a questionnaire form regarding the severity of symptoms and their medication so as to make an evaluation score for the follow-up. The outcome of respiratory symptoms after surgery was as follows: excellent in 23 cases (35.9%); good in 28 (43.8%); fair in 5 (7.8%); poor in 8 (12.5%). The mean respiratory symptom score decreased from 6.3±2.65 to 2.33±2.37. Laparoscopic fundoplication can be an effective treatment for the majority of patients with GERD-related respiratory symptoms.

摘要：

Obstructive sleep apnea syndrome (OSAS) increases the risk of post-surgery complications. This study uses Berlin Questionnaire (BQ) to identify Chinese adult surgical patients who are at a high risk of OSAS and to determine if the BQ could be used to detect potential high risk of adverse respiratory events in the post anesthesia care unit (PACU). Results indicated that only 11.4% of the patients were considered at a high risk of OSAS. Age and body mass index are the key factors for the risk of OSAS prevalence in China and also gender specific. Furthermore, the incidence of adverse respiratory events in the PACU was higher in patients with high risk of OSAS than others (6.8% vs. 0.9%, <0.001). They also stayed longer than others in the PACU (95±28 min vs. 62±19 min, <0.001). Age, high risk for OSAS, and smoking were independent risk factors for the occurrence of adverse respiratory events in the PACU. The BQ may be adopted as a screening tool for anesthesiologists in China to identify patients who are at high risk of OSAS and determine the potential risk of developing postoperative respiratory complications in the PACU.

A pilot study on Paxlovid therapy for hemodialysis patients with severe acute respiratory syndrome coronavirus

《医学前沿（英文）》 doi: 10.1007/s11684-023-1011-0

摘要： We aimed to investigate the safety and efficacy of nirmatrelvir/ritonavir (Paxlovid) therapy for hemodialysis-dependent patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Thirteen hemodialysis patients infected with the Omicron variant of SARS-CoV-2 from April 3 to May 30, 2022, were recruited. Laboratory parameters and chest CT (computed tomography) imaging were analyzed. The treatment group included six patients who received 150 mg/100 mg of Paxlovid orally once daily for 5 days, whereas the control group included seven patients who received basic treatment. No serious adverse reactions or safety events were recorded. Four control patients progressed to moderate disease, and none in the treatment group showed progression of chest CT findings (P < 0.05). Paxlovid therapy tended toward early viral clearance and low viral load on Day 8. Moreover, 83.3% of the patients in the treatment group and 57.1% of the patients in the control group turned negative within 22 days. In the Paxlovid treatment group, we found significantly increased levels of lymphocytes (P=0.03) and eosinophils (P=0.02) and decreased levels of D-dimer on Day 8 compared with those on Day 1. Paxlovid therapy showed a potential therapeutic effect with good tolerance in hemodialysis patients. The optimal dose and effectiveness evaluation must be further investigated in a largeer cohort.

摘要：

The emergence of Middle East respiratory syndrome coronavirus (MERS-CoV) in 2012 brought back memories of the occurrence of severe acute respiratory syndrome coronavirus (SARS-CoV) in 2002. More than 1500 MERS-CoV cases were recorded in 42 months with a case fatality rate (CFR) of 40%. Meanwhile, 8000 cases of SARS-CoV were confirmed in six months with a CFR of 10%. The clinical presentation of MERS-CoV ranges from mild and non-specific presentation to progressive and severe pneumonia. No predictive signs or symptoms exist to differentiate MERS-CoV from community-acquired pneumonia in hospitalized patients. An apparent heterogeneity was observed in transmission. Most MERS-CoV cases were secondary to large outbreaks in healthcare settings. These cases were secondary to community-acquired cases, which may also cause family outbreaks. Travel-associated MERS infection remains low. However, the virus exhibited a clear tendency to cause large outbreaks outside the Arabian Peninsula as exemplified by the outbreak in the Republic of Korea. In this review, we summarize the current knowledge about MERS-CoV and highlight travel-related issues.

摘要： Infection with Middle East respiratory syndrome coronavirus (MERS-CoV) emerged in 2012 as an important respiratory disease with high fatality rates of 40%–60%. Despite the increased number of cases over subsequent years, the number of pediatric cases remained low. A review of studies conducted from June 2012 to April 19, 2016 reported 31 pediatric MERS-CoV cases. In this paper, we present the clinical and laboratory features of seven patients with pediatric MERS. Five patients had no underlying medical illnesses, and three patients were asymptomatic. Of the seven cases, four (57%) patients sought medical advice within 1–7 days from the onset of symptoms. The three other patients (43%) were asymptomatic and were in contact with patients with confirmed diagnosis of MERS-CoV. The most common presenting symptoms were fever (57%), cough (14%), shortness of breath (14%), vomiting (28%), and diarrhea (28%). Two (28.6%) patients had platelet counts of<150 × 10 /L, and one patient had an underlying end-stage renal disease. The remaining patients presented with normal blood count, liver function, and urea and creatinine levels. The documented MERS-CoV Ct values were 32–38 for four of the seven cases. Two patients (28.6%) had abnormal chest radiographic findings of bilateral infiltration. One patient (14.3%) required ventilator support, and two patients (28.6%) required oxygen supplementation. All the seven patients were discharged without complications.

摘要：

Despite the technique of cardiopulmonary bypass (CPB) improved the development of modern cardiac surgery, many factors during CPB have been reported to induce acute respiratory distress syndrome (ARDS). The present study was to investigate which pro-inflammatory factors involved in the early phase of ARDS. Ten patients underwent valve replacement surgery with or without ARDS were enrolled for analysis of pulmonary function and inflammatory factors release including white blood cell (WBC), neutrophils, CD11b, CD18, interleukin (IL)-8 and tumor necrosis factor-α (TNF-α). The results demonstrated that the ratio of arterial oxygen tension/fraction of inspire oxygen (PaO2/FiO2) was greatly reduced in ARDS patients, but only the release of TNF-α was significantly increased, which was reversely correlated to the values of PaO2/FiO2. Also, the count of neutrophils adhesive to pulmonary endothelial cells was significantly increased in ARDS patients. Therefore, we concluded that TNF-α was quickly up-regulated and involved in the pathogenesis of CPB-induced ARDS via guiding primed neutrophils to pulmonary interstitium.

摘要：

The Middle East respiratory syndrome coronavirus was first identified in 2012 and has since then remained uncontrolled. Cases have been mostly reported in the Middle East, however travel-associated cases and outbreaks have also occurred. Nosocomial and zoonotic transmission of the virus appear to be the most important routes. The infection is severe and highly fatal thus necessitating rapid and efficacious interventions. Here, we performed a comprehensive review of published literature and summarized the epidemiology of the virus. In addition, we summarized the virological aspects of the infection and reviewed the animal models used as well as vaccination and antiviral tested against it.

《农业科学与工程前沿（英文）》 2016年 第3卷 第2期   页码 153-160 doi: 10.15302/J-FASE-2016097

摘要： Porcine reproductive and respiratory syndrome (PRRS) is considered to be one of the most important infectious diseases impacting the swine industry and is characterized by reproductive failure in late term gestation in sows and respiratory disease in pigs of all ages. The nonstructural protein 9 gene, , encoding the RNA-dependent RNA polymerase, is generally regarded as fairly conserved when compared to other viral proteins. Antibodies against 9 will be of great importance for the diagnosis and treatment of the causal agent, PRRS virus. A study was undertaken to generate polyclonal antibodies against the immunodominant 9. For this purpose, the 9 was expressed in and subsequently used as an antigen to immunize New Zealand rabbits. Antiserum was identified via an indirect ELISA, and then verified based on the ability to react with both naturally and artificially expressed 9. Results of virus neutralization test showed that this antiserum could not neutralize the PRRSV. Nevertheless, this antiserum as a diagnostic core reagent should prove invaluable for further investigations into the mechanism of PRRS pathogenesis.

摘要：

Periodontitis is the chronic destructive disease of the periodontium (Gums) caused by host bacterial interactions. The effect of such host bacterial interactions in oral cavity also evokes a systemic response. Numerous studies have found common mechanisms of destruction for periodontal diseases and other chronic diseases like diabetes mellitus, atherosclerosis, respiratory diseases, and adverse pregnancy outcomes. Oral colonization by respiratory pathogens appears to be a risk factor for development of respiratory diseases and oral interventions aimed at reducing oral bacterial count have resulted in reduced incidence of these reparatory illness. This reflects the importance of oral hygiene among patients with respiratory illness. This review highlights the association between periodontal diseases and respiratory diseases.

《医学前沿（英文）》 2007年 第1卷 第2期   页码 215-218 doi: 10.1007/s11684-007-0041-3

摘要： From April to June, 2004, an outbreak of acute upper respiratory tract infections (AURTI) occurred in the north area of Jiangsu Province, China. Twenty throat swabs were collected with 13 of them presenting an adenovirus (Ad)-like cytopathogenic effect on HEp-2. These were verified as Ad by the electron microscope, direct immunofluorescence assay and Ad primer-mediated PCR. Moreover, they were identified as adenovirus type 3 (Ad3) by type-specific PCR and sequencing of the amplification products. Subsequent serologic studies were carried out to finally diagnose and document the outbreak. The neutralization test of paired serum of six in nine cases show obviously increased antibodies titers. The positive rate of IgM, IgG and recovery phase neutralization antibodies of the cases were 3.7%, 44.4% and 59.5% respectively while those of the controls were 0%, 8.3% and 33.3% respectively. The values of Chi-Square were 0.510, 0.018 and 0.226 respectively. The concordance between IgG detected by ELISA and neutralization anti bodies detected by the neutralization test was 61.4% and the value of Kappa was 0.070. By the serologic study, we can definitively diagnose that this outbreak of acute respiratory infections was caused by Adenovirus 3.

porcine sialoadhesin V-set Ig-like domain sheds some light on its role in porcine reproductive and respiratory

Jie HOU,Rui LI,Hongfang MA,Songlin QIAO,Gaiping ZHANG

《农业科学与工程前沿（英文）》 2016年 第3卷 第1期   页码 65-71 doi: 10.15302/J-FASE-2016086

摘要： Porcine reproductive and respiratory syndrome (PRRS) is characterized by reproductive failures in sows and respiratory diseases in pigs of all ages. PRRS virus (PRRSV) is its causative agent and has caused huge economic losses in the swine industry. Porcine sialoadhesin (pSn) is a putative receptor of PRRSV. Previous studies have shown that a pSn V-set Ig-like domain is significant in PRRSV infection. However, its structural details are not fully known, hindering our deep understanding of PRRSV infection. In this study, we successfully cloned, expressed and purified the pSn V-set Ig-like domain in S2 cells. Then we tried to crystallize the target protein and predicted its structure. This will establish the foundation for the further structural study of pSn, deepen our understanding of the invasion mechanism of PRRSV, and support the structural information for the development of clinical drugs and vaccines against PRRSV.

摘要：

The Middle East respiratory syndrome coronavirus (MERS-CoV) is a novel zoonotic pathogen. In 2012, the infectious outbreak caused by MERS-CoV in Saudi Arabia has spread to more than 1600 patients in 26 countries, resulting in over 600 deaths. Without a travel history, few clinical and radiological features can reliably differentiate MERS from SARS. But in real world, comparing with SARS, MERS presents more vaguely defined epidemiology, more severe symptoms, and higher case fatality rate. In this review, we summarize the recent findings in the field of MERS-CoV, especially its molecular virology, interspecies mechanisms, clinical features, antiviral therapies, and the further investigation into this disease. As a newly emerging virus, many questions are not fully answered, including the exact mode of transmission chain, geographical distribution, and animal origins. Furthermore, a new protocol needs to be launched to rapidly evaluate the effects of unproven antiviral drugs and vaccine to fasten the clinical application of new drugs.

《农业科学与工程前沿（英文）》 2014年 第1卷 第2期   页码 114-120 doi: 10.15302/J-FASE-2014022

摘要： Porcine reproductive and respiratory syndrome virus (PRRSV), a single-stranded RNA virus, mainly infects cells of monocyte/macrophage lineage. Recently, host microRNAs were shown to be capable of modulating PRRSV infection and replication by multiple ways such as targeting viral genomic RNA, targeting viral receptor and inducing antiviral response. MicroRNAs are small RNAs and have emerged as important regulators of virus-host cell interactions. In this review, we discuss the identified functions of host microRNAs in relation to PRRSV infection and propose that cellular microRNAs may have a substantial effect on cell or tissue tropism of PRRSV.

摘要：

自新型冠状病毒肺炎（coronavirus disease 2019, COVID-19）疫情发生以来，中国大多数的病例集中在武汉市。虽然早期病例数和死亡人数迅速增加，但通过采取多种防控措施，疫情得以快速遏制。纵观全球，疫情已蔓延至全球六大洲的187个国家，确诊病例数已超过300万，这一数字仍在快速增长。在此特殊背景下，有必要对我国疫情防控措施开展科学的、定量的评估，为全球疫情防控提供决策依据。为此，本研究评估了临床诊断标准实施和全城症状排查对武汉市疫情控制的贡献。考虑COVID-19的传播机理、隔离措施等，建立SEIR+Q传播动力学模型。基于武汉市截至2020年2月14日官方公布的每日确诊病例数和未确诊的临床诊断病例数进行建模，并预测2月14日以后的疫情态势。基于实际疫情数据，与模型预测趋势相比较，评价防控措施效果。结果显示，若维持2月14日以前防控措施不变，那么预测将于3月25日和4月29日，每日新增病例数分别降至100例和10例以下，将于5月31日首次现零。而事实上，截至3月6日，武汉市每日新增病例数降至100例以下，截至3月11日降至10例以下，3月18日首次实现零增长，较之模型预测结果分别提前了19 d、49 d和74 d。截至3月30日，实际累计病例数为50 006例，比模型预测值减少19 951例。有效再生数[effective reproductive number, R(t)]分析显示，2月6−10日的第一次全城症状排查后，R(t)显现出下降趋势，2月12−14日的临床诊断标准实施和2月17−19日的第二次全城症状排查后，R(t)显现出较大的降幅，与实际情况较为一致。综上所述，武汉市临床诊断标准的实施和全城症状排查等综合防控措施成效显著，可为世界各国的疫情防控决策提供科学依据。
