ABSTI~CT Lung cancer incidence has increased rapidly in China over the last 20 years, especially in females. Among the 183 registered worldwide populations, lung cancer incidence in males was ranked as the 73rd, 74th, 127th and 23rd respectively for Shanghai, Tianjin, Qidong and Hong Kong, and in females the 52nd, 13th, 102nd and 23rd. The sex ratio (M/F) ranged from 1.5 to 3.5 for most areas. The ratio of squamous/ adenocarcinoma was 2.01 in males and 0.67 in females in Tianjin, 0.97 and 0.28 in Hong Kong, 1.00 and 0.61 in the US white population and 1.18 and 0.49 in US blacks. Much research on risk factors have been conducted and documented including the following: genetic predisposition/polymorphism, smoking/coal soot and DNA adduct, cytochrome p450-1A1 (CYP1A1), glutathione S-transferase-M (GST-M), viral infection/HPV infection, high background radiation, family history, tobacco consumption, mental health, prior lung diseases, coal soot indoor air pollution, cooking fume indoor air pollution, hormones, diet, occupational exposure, outdoor air pollution, socioeconomic level/education, alcohol consumption and their interactions(addition/synergy). Based on current information we should carefully devise a plan to control lung cancer that can be put into practice.

Neurogenic pulmonary edema (NPE) is occasionally observed in patients with traumatic brain injury (TBI); however, this condition is often underappreciated. NPE is frequently misdiagnosed due to its atypical clinical performance, thus delaying appropriate treatment. A comprehensive management protocol of NPE in patients with TBI has yet to be established. The current study reported the case of a 67-year-old man with severe TBI who was transferred to our intensive care unit (ICU). On day 7 after hospitalization, the patient suddenly suffered tachypnea, tachycardia, systemic hypertension and hypoxemia during lumbar cistern drainage. Intravenous diuretics, tranquilizer and glucocorticoid were administered due to suspected left heart failure attack. Chest radiography examination supported the diagnosis of pulmonary edema; however, hypotension and hypovolemia were subsequently observed. Pulse index continuous cardiac output (PiCCO) hemodynamic monitoring and bedside echocardiography were performed, which excluded the diagnosis of cardiac pulmonary edema, and thus the diagnosis of NPE was confirmed. Goal-directed therapy by dynamic PiCCO monitoring was then implemented. In addition, levosimendan, an inotropic agent, was introduced to improve cardiac output. The patient had complete recovered from pulmonary edema and regained consciousness on day 11 of hospitalization. The current case demonstrated that PiCCO monitoring may serve a central role in the integrated management of NPE in patients with TBI. Levosimendan may be a potential medicine in treating cardiac dysfunction, along with its benefit from improving neurological function in NPE patients.

Objective The purpose of this study was to explore the effect of WeChat‐based remote follow‐up management on reducing the home care burden and anxiety of parents of premature infants. Methods A randomized controlled study was conducted in our hospital, with 150 premature infants enrolled in this study, each with 75 cases in the intervention group and the control group. WeChat‐based remote follow‐up management was performed in the intervention group after discharge, while traditional outpatient follow‐up management was performed in the control group. Zarit Burden Interview (ZBI) scale as the primary outcome was used to compare the parental care burden between the two groups. Results At the 1‐month follow‐up, the ZBI (37.1 ± 8.3 vs. 54.2 ± 10.5 [mean ± SD], mean difference: 17.1, the 95% confidence interval for the mean difference: [14.07, 20.13], P = 0.016), Family Caregiver Task Inventory (FCTI) scale (23.1 ± 5.2 vs. 33.4 ± 6.7 [mean ± SD], mean difference: 10.3, the 95% confidence interval for the mean difference: [8.38, 12.22], P = 0.023), Self‐Rating Anxiety Scale (SAS) (49.6 ± 8.5 vs. 60.2 ± 10.8 [mean ± SD], mean difference: 10.6, the 95% confidence interval for the mean difference: [7.49,13.71], P = 0.021) and Self‐Rating Depression Scale (SDS) (48.2 ± 9.5 vs. 58.8 ± 11.2 [mean ± SD], mean difference: 10.6, the 95% confidence interval for the mean difference: [7.28, 13.92], P = 0.019) scores of the intervention group were lower than those of the control group, and the lower scores indicate better outcomes. Conclusion WeChat‐based remote follow‐up management of premature infants after discharge can effectively improve parents' ability to care and their psychological state and reduce burden of care.
