ObjectiveTo assess the relationship between the estimated glomerular filtration rate (eGFR) and the severity of coronary artery stenosis in elder people. MethodsSix hundred and fifty-seven patients who underwent selective coronary artery angiography were divided into 3 groups according to age: group Ⅰ (202 patients aged <60 years), group Ⅱ (181 patients aged from 60 to 69 years) and group Ⅲ (274 patients aged ≥70 years). According to the simplified MDRD equation,impaired renal function and severe renal dysfunction, respectively. Clinical features and the severity of coronary artery stenosis were compared among the 3 groups. ResultsThe level of average eGFR tended to he decreased with the narrowed coronary arteries. The difference of average eGFR between patients with muhivessel versus two-vessel coronary artery disease was of statistical significance in Group Ⅲ(P = 0. 035). After controlling for the effects of smoking, hypertension, dyslipidemia,aging, and diabetes, the Gensini score which reflected the severity of coronary artery stenosis was negatively correlated with the level of eGFR (r =-0. 110, P = 0. 005). ConclusionsIt suggests that the eGFR decrease is associated with the severity of coronary artery stenosis, and there is a linear correlation between eGFR and Gensini score in elder people, eGFR can be used to evaluate the severity of coronary artery disease and prognosis.

To design a military hospital bonus accounting system. The system used Java as the fore-ground development tool and SQL Server 2005 as the background database, which extracted data from the military hospi-tal cost accounting management system to calculate the bonus with some formula. The system had four functional modules to complete department benefit accounting, bonus calculation, bonus summarization and bonus inquiry. The system decreases the workload and contributes to the standardized management of the accounting.

Lung adenocarcinoma (LUAD) is the most common subtype of lung cancer and one of the main causes of cancer-related deaths. In the past decade, with the widespread use of computed tomography (CT) in routine screening for lung cancer, the incidence of LUAD presenting as small pulmonary nodules radiologically, has increased remarkably. The mechanisms of the occurrence and progression of LUADs are complex, and the prognoses of patients with LUAD vary significantly. Although significant progress has been made in targeted therapy and immunotherapy for LUADs in recent years, the drug resistance of tumor cells has not been effectively overcome, which limits the benefits of patients. With the accomplishment of the Human Genome Project, sequencing-based genomic and transcriptomics have come into the field of clinical and scientific researches. Single-cell sequencing, as a new type of sequencing method that has captured increasing attention recently, can perform specific analysis of cell populations at single-cell level, which can reveal the unique changes of each cell type. Single-cell sequencing can also provide accurate assessment on heterogeneous stromal cells and cancer cells, which is helpful to reveal the complexity of molecular compositions and differences between non- and malignant tissues. To sum up, it is an urgent need for clinicians and basic scientists to deeply understand the pathogenesis and development of LUAD, the heterogeneity of tumor microenvironment (TME) and the mechanism of drug resistance formation through single-cell sequencing, so as to discover new therapeutic targets. In this paper, we reviewed and summarized the application and progress in single-cell sequencing of LUADs.

BACKGROUND: A retrospective review of the surgical treatment of refractory chest tumors involving the heart or large vessels with cardiopulmonary bypass (CPB). METHODS: To summarize 11 cases of chest tumor patients who had undergone cardiopulmonary bypass surgery from January 2008 to May 2017 in our hospital, and analyze the general condition, clinical characteristics, treatment methods, postoperative hospitalization time, complications and follow-up results of all patients. RESULTS: All 11 patients were operated with cardiopulmonary bypass. Total resection of tumors in 8 cases and most of the excision in 3 cases. 1 case of left atrial metastatic leiomyosarcoma were excised in the left atrium, and then the right lung resection was performed. 1 case of left lung central lung cancer resection through the median sternum incision. 2 cases underwent pulmonary artery repair at the same time, 3 cases underwent partial pericardiectomy and 3 cases underwent pulmonary wedge resection at the same time. All the patients were effectively relieved after the operation. No death rate in hospital and 30 days after operation. 3 cases of postoperative pulmonary infection were recovered after the treatment of antibiotics. 1 case of lymphoma relapsed 6 months after surgery and died one year later. 1 case of pericardial fibrosarcoma had local recurrence and extensive metastasis at 13 months after operation, and died after 15 months. 1 case of pulmonary leiomyosarcoma were found to have local recurrence 15 months after the operation and were relieved after chemotherapy. The remaining 8 patients survived, and no obvious recurrence and distant metastasis were found in the computed tomography (CT) examination. CONCLUSIONS The CPB assisted surgical treatment can be performed for patient of refractory chest tumors involving the heart or large vessels. It can improve the surgical resection rate of refractory chest tumors, effectively alleviate the effects on respiratory and circulatory functions, and significantly prolong the survival period of these patients.

Lung cancer leads to the highest cancer-related morbidity and mortality worldwide. With the development of multi-slice spiral computed tomography technology and the implement of lung cancer screening, more and more lung nodules have been discovered, many of which are multiple pulmonary nodules. These pulmonary nodules are usually diagnosed as multiple primary lung adenocarcinomas from a pathological perspective. For multiple nodules with different imaging features, the preferred treatment methods are different, and the treatment of each lung nodule is still controversial. In recent years, the interactions between multiple lesions and the evolution of the lesions as well as the inter-tumoral and intratumoral homogeneity and heterogeneity of the genomics also arouse attention. Our review gathered the research progress in multiple pulmonary nodules from the points of histopathology, genomics and surgical management.
