101 women; median age was 47•5 years (range 7-90). The most common symptoms at onset of illness were fever (193 [84%] patients), cough (159 [69%] patients), and sputum production (98 [43%] patients). Diarrhoea was observed in 49 (21%) patients. Patients with diarrhoea were older and were more likely to have comorbidities than patients without diarrhoea (table). A greater proportion of patients admitted to hospital had diarrhoea as the outbreak progressed: nine (43%) of 21 patients admitted between Feb 12 and March 6, 2020, had diarrhoea versus 40 (19%) of 209 patients admitted between Jan 19 and Feb 11, 2020.More patients with diarrhoea showed severe symptoms of pneumonia hospitals in Guangdong province, two in Hubei province, and ten in Jiangxi province) between Jan 19, 2020, and March 6, 2020. Most patients were admitted because of fever, cough, dyspnoea, and chest CT findings consistent with COVID-19 pneumonia. Diagnosis of COVID-19 was based on positive SARS-CoV-2 RNA tests. Two patients with pre-existing digestive diseases were excluded from our analysis. The analysis was approved by the institutional review boards of Sun Yat-sen University and the participating hospitals. Full details of the methods used are in the appendix (p 1).The clinical and demographic characteristics of the 230 patients analysed are shown in the appendix (p 2). There were 129 men and

High expression of CD73 can be an independent and useful biomarker for predicting the poor survival of patients with CRC.

This article constructs an environmental logistics performance index (ELPI) for assessing the overall performance in green transportation and logistics practices of 112 countries. The index is measured by logistics performance index (LPI), CO2 emissions and oil consumption from the transport sector, using a range-adjusted measure (RAM) of the data envelopment analysis (DEA). ELPI effectively reflects the tradeoff between logistics efficiency and environmental protection in transportation. This article analyzes the impact of income and region on ELPI scores and discusses those countries’ reduction potential in oil consumption intensity and carbon intensity. The main finding of the research work is that ELPI is strongly correlated with LPI, and countries with high performance in LPI generally perform well in ELPI. Similar to the characteristics of LPI, ELPI is also closely related to income and region. During our study period, high income countries performed best, while Sub-Saharan Africa countries performed worst. However, some exceptions such as Venezuela, RB and Benin, indicate that the level of development of logistics performance and green transportation can outperform or lag behind their income or region group peers.

Preoperative understanding of the vascular variations and the mutual relationship among LCA, IMA and IMV could be obtained by 3D-CTA, which would further help surgeons to set detailed plans for laparoscopic rectal cancer surgery.
