Meta Analysis
Risk factors for the exacerbation of patients with 2019 Novel Coronavirus: A meta-analysis.
Many studies have reported the risk factors for exacerbations in patients with 2019 novel coronavirus (2019-nCoV). This study aims to perform the meta-analysis of risk factors for the exacerbation of the novel coronavirus-infected pneumonia (NCIP). PubMed, Embase and Google scholar have been searched. ⋯ After comparing the patients between intensive care (ICU) group and non-ICU group, several important factors were found to significantly increase the risk of exacerbations in patients with NCIP, and they included hypertension (RR=2.34; 95% CI=1.21 to 4.51; P=0.01), cardiovascular diseases (RR=2.28; 95% CI=1.13 to 4.58; P=0.02), COPD (RR=7.65; 95% CI=1.24 to 47.13; P=0.03), dyspnea (RR=2.89; 95% CI=2.05 to 4.08; P<0.00001), myalgia or fatigue (RR=1.24; 95% CI=1.01 to 1.52; P=0.04), but several factors such as gender, Huanan Seafood Wholesale Market exposure, diabetes, chronic liver disease, malignancy, fever, cough, expectoration, headache and diarrhoea appeared to have no obvious effect on the exacerbation of pneumonia. In addition, as the exacerbation of pneumonia, some complications had the high probability to occur according to the meta-analysis of acute respiratory distress syndrome (ARDS) (RR=13.95; 95% CI=6.20 to 31.41; P<0.00001), shock (RR=24.29; 95% CI=4.66 to 126.69; P=0.0002), acute cardiac injury (RR=10.32; 95% CI=3.05 to 34.96; P=0.0002) and acute kidney injury (RR=5.90; 95% CI=1.32 to 26.35; P=0.02) between two groups. Several risk factors were confirmed to significantly improve the risk of exacerbation in patients with NCIP, which was very important for the exacerbation prediction and treatment of these patients.

Aim: CC chemokine receptor 9 (CCR9) interacts with its exclusive ligand CCL25, resulting in promoting tumor progression and metastasis. However, the effect and mechanisms of CCR9 on lung adenocarcinoma distant metastasis remain largely unknown. To preliminary clarify the underlying mechanisms, we investigate the correlation between CCR9 and ALDH1A1+cancer stem cells (CSCs), as well as the effect of CCR9 on the migration and invasion of CSCs. ⋯ Additional application of anti-CCR9 antibody reversed the CCL25-induced migration and invasion of CSCs. Conclusions: In summary, our study demonstrated that CCR9/CCL25 promoted the migration and invasion of CSCs, which might contribute to distant metastasis and poor overall survival. Our findings provided evidence that CCR9/CCL25 could be used as novel therapeutic targets for lung adenocarcinoma.

Randomized Controlled Trial
Comparison of Biochemical Recurrence After Robot-assisted Laparoscopic Radical Prostatectomy with Volatile and Total Intravenous Anesthesia.
Aims: Recurrence after cancer surgery is a major concern in patients with cancer. Growing evidence from preclinical studies has revealed that various anesthetics can influence the immune system in different ways. The current study compared the long-term biochemical recurrence of prostate cancer after robot-assisted laparoscopic radical prostatectomy (RALP) in terms of selection of anesthetic agent between total intravenous anesthesia (TIVA) with propofol/remifentanil and volatile anesthetics (VA) with sevoflurane or desflurane/remifentanil. ⋯ Results: Both TIVA and VA groups showed identical biochemical recurrence-free survivals at all-time points after RALP. The following predictive factors of prostate cancer recurrence were determined by Cox regression: colloid input [hazard ratio (HR)=1.002, 95% confidence interval (CI): 1.000-1.003; P = 0.011], initial prostate-specific antigen level (HR=1.025, 95% CI: 1.007-1.044; P = 0.006), and pathological tumor stage 3b (HR=4.217, 95% CI:1.207-14.735; P = 0.024), but not the anesthetic agent. Conclusions: Our findings demonstrate that both TIVA with propofol/remifentanil and VA with sevoflurane or desflurane/remifentanil have comparable effects on oncologic outcomes in patients undergoing RALP.

Background: To investigate the relationship between serum iron status and renal outcome in patients with type 2 diabetes mellitus (T2DM). Methods: Chinese patients (n=111) with T2DM and biopsy-proven diabetic nephropathy (DN) were surveyed in a longitudinal, retrospective study. Serum iron, total iron-binding capacity, ferritin, and transferrin were measured at the time of renal biopsy. ⋯ Moreover, tubular epithelial cells in DN exhibited a higher deposition of iron and transferrin expression compared with healthy controls. Conclusions: Low serum transferrin concentration was associated with diabetic ESRD in patients with T2DM. Free iron nephrotoxicity and poor nutritional status with accumulated iron or transferrin deposition might contribute to ESRD.

Oxidative stress and inflammation are two interlinked events that exist simultaneously in metabolic syndrome (MetS) and its related complications. These pathophysiological processes can be easily triggered by each other. This review summarizes the current evidence from animal and human studies on the effects of vitamin C in managing MetS. ⋯ Oral supplementation of vitamin C also improved MetS conditions. It has been postulated that the positive outcomes of vitamin C may be in part mediated through its anti-oxidative and anti-inflammatory properties. These observations suggest the importance of MetS patients to have an adequate intake of vitamin C through food, beverages or supplements in order to maintain its concentration in the systemic circulation and potentially reverse MetS.
