Early identification of severe patients with coronavirus disease 2019 (COVID-19) is very important for individual treatment. We included 203 patients with COVID-19 by propensity score matching in this retrospective, case-control study. The effects of serum lactate dehydrogenase (LDH) at admission on patients with COVID-19 were evaluated. We found that serum LDH levels had a 58.7% sensitivity and 82.0% specificity, based on a best cut-off of 277.00 U/L, for predicting severe COVID-19. And a cut-off of 359.50 U/L of the serum LDH levels resulted in a 93.8% sensitivity, 88.2% specificity for predicting death of COVID-19. Additionally, logistic regression analysis and Cox proportional hazards model respectively indicated that elevated LDH level was an independent risk factor for the severity (HR: 2.73, 95% CI: 1.25-5.97; P=0.012) and mortality (HR: 40.50, 95% CI: 3.65-449.28; P=0.003) of COVID-19. Therefore, elevated LDH level at admission is an independent risk factor for the severity and mortality of COVID-19. LDH can assist in the early evaluating of COVID-19. Clinicians should pay attention to the serum LDH level at admission for patients with COVID-19.
Background & Aims The eradication rate of Helicobacter pylori (H pylori) has decreased largely because of the antibiotic resistance. We aimed to evaluate the effectiveness and safety of furazolidone‐containing quadruple regimens for H pylori eradication. Methods This was an observational study of furazolidone‐containing quadruple regimens for H pylori infection in real‐world settings. Data sets were collected from the medical records and telephone interviews of patients referred to a specialist clinic for suspected H pylori reinfection from January 1, 2015, to January 1, 2018, at the First Affiliated Hospital of Nanchang University. Main outcome measures were the eradication rate and adverse reactions during medication. Results Among 584 patients with H pylori infection that met the inclusion criteria, 561 (96.1%) were treated for the first time, 19 (3.3%) had one, and 4 (0.5%) had two or more prior to furazolidone‐containing quadruple regimens. The eradication rates for 10‐day and 14‐day regimens were 93.7% (95% CI: 91.5%‐95.9%) vs 98.2% (95% CI: 95.6%‐99.3%), respectively (P = 0.098). Adverse drug reactions occurred in 8.2% (48/584) with abdominal discomfort being the most common symptom. Overall adverse events with 10‐day regimens were lower than 14‐day regimens (6.1% vs 17.4%, P < 0.001). Logistic regression analysis indicated that poor adherence (adjusted odds ratio [AOR] = 46.5, 95% CI: 9.7‐222.4) was correlated with failed eradication. Adverse drug reactions during medication were related to smoking and tobacco status, alcohol intake history, regimens combined with tetracycline, and poor adherence (all P < 0.05). Conclusions Furazolidone‐containing quadruple regimens proved both safe and highly effective in a real‐world setting.
Subtropical evergreen broad-leaved forest (EBLF) is a widespread vegetation type throughout East Asia that has suffered extensive deforestation and fragmentation. Selection and successful propagation of native tree species are important for improving ecological restoration of these forests. We carried out a series of experiments to study the propagation requirements of indigenous subtropical tree species in Southwest China. Seeds of 21 tree species collected from the natural forest were materials for the experiment. This paper examines the seed germination and seedling growth performance of these species in a nursery environment. Germination percentages ranged from 41% to 96% and were ě50% for 19 species. The median length of germination time (MLG) ranged from 24 days for Padus wilsonii to 144 days for Ilex polyneura. Fifteen species can reach the transplant size (ě15 cm in height) within 12 months of seed collection. Nursery-grown seedlings for each species were planted in degraded site. Two years after planting, the seedling survival rate was >50% in 18 species and >80% in 12 species. Based on these results, 17 species were recommended as appropriate species for nursery production in forest restoration projects. Our study contributes additional knowledge regarding the propagation techniques for various native subtropical tree species in nurseries for forest restoration.
With China's adoption of principles-based international accounting standards and its convergence with International Accounting Standard 39 (IAS 39), Chinese companies have discretion under the original Accounting Standards for Enterprises 22 (CAS 22) as to how they account for the initial measurement, sale, and subsequent reclassification of financial assets. We use a Chinese company ('Company A') as a case study to illustrate how earnings are managed to exploit this discretion. We document that the company reclassifies its available for sale equity investments as long-term equity investments to decrease the volatility of the company's apparent profits. We also make some predictions regarding how the company will handle its financial assets under the new standard, which is the same as IFRS 9. Our research contributes to the continuous improvement of China's accounting standards and has implications for regulators of the capital market.
lncRNAs have been shown to be fundamentally involved in intestinal mucosal regeneration, protection, and epithelial barrier function. It may emerge as new and potential factors to be evaluated in the intestinal barrier diseases caused by acute pancreatitis, inflammatory bowel diseases, and imbalance of intestinal flora.
