A study addressing the influence of type 2 diabetes on the prognosis of acute-on-chronic liver failure patients was reviewed. Some statistical deficiencies were found in the reviewed article, and the sample size was too small to support the study. In addition, age should have been considered as one of the prognostic factors., Competing Interests: Conflict-of-interest statement: Each author has reviewed the statement by the Baishideng Publishing Group on conflict of interest, and every author stated that there is no conflict of interest., (©The Author(s) 2022.

Rubus chingii Hu, a member of the rosaceae family, is extensively distributed in China and Japan. Its unripe fruits (Fupenzi in Chinese) have a long history of use as an herbal tonic in traditional Chinese medicine for treating various diseases commonly associated with kidney deficiency, and they are still in use today. Phytochemical investigations on the fruits and leaves of R. chingii indicate the presence of terpenoids, flavonoids, steroids, alkaloids, phenylpropanoids, phenolics, and organic acids. Extracts or active substances from this plant are reported to have various pharmacological properties, including antioxidant, anti-inflammatory, antitumor, antifungal, antithrombotic, antiosteoporotic, hypoglycemic, and central nervous system-regulating effects. This review provides up-to-date information on the botanical characterizations, traditional usages, chemical constituents, pharmacological activities, toxicity, and quality control of R. chingii. Possible directions for future research are also briefly proposed. This review aims to supply fundamental data for the further study of R. chingii and contribute to the development of its clinical use., (Copyright © 2020 China Pharmaceutical University.

Objective: To compare the epidemiological and clinical features of lower respiratory tract infection (LRTI) caused by influenza virus A (IVA) and influenza virus B (IVB) in children., Methods: The clinical data of 366 children with LRTI caused by influenza virus (IV), who were hospitalized in Yuying Children&prime;s Hospital of Wenzhou Medical University between 2010 and 2014, were analyzed retrospectively, and there were 272 cases caused by IVA and 94 cases caused by IVB., Results: IV was mainly prevalent from December to March of the next year, with the predominance of IVA. There were small peaks of IVA prevalence in July or September every other year, and IVB was prevalent from December to March of the next year every other year. The children with LRTI caused by IVA alone had a significantly higher white blood cell (WBC) count and significantly higher percentages of children with increased WBC, abnormal serum sodium, and abnormal serum potassium than those caused by IVB alone (P<0.05). However, there were no significant differences in age, sex, underlying diseases, clinical manifestations, and co-infection rate with bacteria or atypical pathogens between the two groups (P>0.05). The rate of co-infection with respiratory syncytial virus (RSV) was significantly higher in the IVB group than in the IVA group (P<0.01)., Conclusions: IVA is prevalent in winter and spring every year and has small peaks in summer every other year, while IVB is prevalent in winter and spring every other year. Compared with IVB, IVA causes more cases of increased WBC and electrolyte disturbance. The children infected with IVB are more likely to be co-infected with RSV. The children with LRTI caused by IVA and IVB have similar clinical manifestations.

This study aimed to clarify the association between angiotensin-converting enzyme (ACE) gene polymorphisms and infant wheezing, and to determine whether an association may contribute to early prediction of persistent wheezing and asthma. The study cohort comprised 149 patients with asthma, 169 patients with wheezing but no clinical diagnosis of asthma and 165 healthy control subjects. The insertion/deletion (I/D) polymorphism of the ACE gene was determined by polymerase chain reaction. Total serum immunoglobulin E was determined for the wheezy group and a 4-year follow-up study was carried out to observe wheezing relapse. Significant differences were found between patients and controls in allele frequency and genotype distribution. The DD genotype was more frequent in patients in the wheezing and asthma groups than in the control subjects. Patients with the DD genotype had a higher frequency of relapse than patients expressing the ID or II genotypes. It is concluded that the DD genotype of ACE is a risk factor for recurrent wheezing in early childhood.
