To analyze the clinical characteristics,imaging and pathological features of 1 case with partial right lung atelectasis and summarize the relevant domestic reports on the false positive of positron emission tomography-computed tomography (PET-CT) and tumor markers.The patient was diagnosed by PET-CT as partial atelectasis and there were progressive increases of CEA,CA199 and CA242.But site of lesion biopsy showed no malignancy.After treatments of anti-inflammatory and eliminating phlegm,the tumor markers returned to normal and the lesion site had excellent re-expansion.The detection of PET-CT plus tumor markers may have false positive probability.The reason is probably related with inflammation and glandular secretion of lesion site.

Objective To study a feasible technology plan for information communication between doctors and patients.Methods Based on three-layer B/W/S and Windows2003 Server,MS SQL Server was used for database administration.The Apache Tomcat 5.5 was adopted as Web server and Web services were realized by using JSP(Java Server Page).Results Health care information was collected and integrated in medical information platform of clinical department which was connected into Internet directly.The information platform established communication way between doctors and patients and it had functions for chief complaint,diagnosis,reservation and revisit.Conclusion Communication between doctors and patients are realized.

Objective To explore the value of metagenomic next-generation sequencing (mNGS) in the diagnosis and treatment of severe pneumonia after renal transplantation .Methods A total of 38 patients with severe pneumonia after renal transplantation from October 2017 to December 2018 were selected and divided into experimental group (A ,n= 15)and control group (B ,n= 23) based upon whether mNGS of bronchoalveolar lavage fluid was employed for detecting pathogenic microorganisms .Positive rate ,clinical acceptance rate ,hospitalization time ,hospitalization expenses and 28-day mortality rate of two methods were compared .Results Positive rate and clinical acceptance rate of mNGS were higher in experimental group than those in traditional experimental and control groups ( P < 0 .05 ) . Hospitalization time , hospitalization expenses and 28-day mortality of experimental group were lower than those of control group (P< 0 .05) .No significant inter-group difference existed in 90-day mortality (P> 0 .05) .Conclusions For patients with severe pneumonia after renal transplantation , mNGS of bronchoalveolar lavage fluid can improve positive rate of etiological diagnosis and clinical acceptance rate and reduce hospitalization time , hospitalization expenses and 28-day mortality .
