Objectives To analyze the effect of glucocorticoids on acute respiratory distress syndrome (ARDS) in adult patients. Method English and Chinese literature about the glucocorticoids treatment for ARDS were electronically searched. Meta-analysis was performed by Rev Man 5.0 software after the data of qualified studies were included in consistence with the criteria of inclusion and exclusion. Results Eight studies including 679 cases(steroid group 366, control group 313) met the inclusion criteria. Resuhs of meta-analysis showed that there were significant differences( P <0.05), between the steroid group and the control group, in mortality in all cases, mortality in patients treated at early stage, mortality in patients treated with low dose steroids, and PaO_2/FiO_2;the relative risks(RRs)/standardized mean difference(SMDs) and 95% confidence intervals(CIs) are 0.55(0. 34 ～ 0.87), 0.49(0.28 ～ 0.86), 0.46(0.24 ～ 0.88) and 2.99(0.63 ～ 5.34). There were no significant differences in mortality in patients treated during late stage, mortality in patients treated with high dose steroids and number of nosocomial infections(P > 0.05). Conclusions Low-dose glucocorticoids or routine dose glucocorticoids given during early stage can reduce mortality in patients with ARDS; the oxygenation of patients is significantly improved after steroid therapy; incidence of infectious complications is neither increased nor decreased by steroid therapy.

Surgical resection is still the mainstay for treatment of intrahepatic cholangiocarcinoma (ICC).Gemcitabine and cisplatin is a systemic therapy practice standard for patients with non-resectable ICC.Neoadjuvant therapy with liver transplantation may be a new therapeutic option for patients with ICC.In addition, radiotherapy, hepatic intra-arterial therapy, ablation therapy and molecular targeted therapy are important components of comprehensive therapy for ICC.

Objective To investigate the effect of hepatitis C virus (HCV) genotype on antiviral therapy in patients with human immunodeficiency virus (HIV)/HCV coinfection in Henan province.Methods A total of 129 patients were coinfected with HIV and HCV, among whom, 70 were HCV 1b genotype and 57 HCV 2a genotype.And 131 patients were HIV single infection.Immunological failure rate, virological suppression, CD4+ T lymphocyte counts and liver and renal function after antiretroviral therapy (ART) were compared among the three groups.Flow cytometry was used to count CD4+ T lymphocytes and polymerase chain reaction amplification was used to detect HIV RNA.The liver and renal function were tested by automatic biochemical analysis.Statistical analysis was conducted by χ2 test, analysis of variance and LSD-t method.ResultsImmunological failure rate in HCV 1b group, HCV 2a group and HIV single infection group were 7.14% (5/70), 15.79% (9/57) and 9.92% (13/131), respectively.There was no significant statistical difference among the three groups (χ2=2.59, P>0.05).The CD4+ T lymphocyte counts in three groups were (614±258), (529±245), and (518±243) cells/μL, respectively.The difference was statistically significant (F=3.17, P<0.05).The virus inhibition rates of three groups were 87.0% (HCV 1b), 78.2% (HCV 2a), and 82.3% (HIV single infection).The HIV virus failure rates were 8.6% (HCV 1b), 14.5% (HCV 2a), and 13.1% (HIV single infection).There was no significant difference among three groups (χ2=1.967, P>0.05).The levels of aspartate transaminase, alanine aminotransferase and total bilirubin in HCV 1b group and HCV 2a group were all significantly higher than those in HIV single infection group (F=27.38, 15.22 and 7.33, respectively, all P<0.05), while there was no significant difference between HCV 1b and HCV 2a groups (t=1.27, 0.29 and 1.59, respectively, all P>0.05).Conclusions The main HCV genotypes in patients with HIV/HCV coinfection by blood transmission are HCV 1b and HCV 2a in Henan province.HIV/HCV coinfection does not affect the effect of ART, but could aggravate the liver damage in acquired immune deficiency syndrome patients.

This study aimed to investigate the protective effects of Baibu Tang on bleomycin-induced pulmonary fibrosis in mice. After intratracheally giving bleomycin(3. 5 mg/kg), mice were orally administered Baibu Tang once a day for 14 consecutive days, takingnintedanib as a positive control. The anti-fibrotic effects were assessed by the hydroxyproline level and the histopathological changes in H&E or Masson stained lung tissues. The results revealed that the lung coefficient, hydroxyproline content, inflammation and collagen deposition were increased significantly in the lung tissue of the model mice. Both ethanol and water extracts of Baibu Tang significantly improved all the pathological indexes in mice, but the effect of the ethanol extract was better than that of the water extract. Baibu Tang with Baibu(root of Stemona tuberosa)containing different components(neotuberostemonine, tuberostemonine and stemoninine, respectively)could significantly reduce hydroxyproline level and collagen deposition in the lung tissue of bleomycin-induced mice, and there was no significant difference in their activity. This result showed that the changes in the chemical composition of Stemona tuberosa(Baibu, monarch drug for Baibu Tang)have little effect on the anti-fibrosis activity of Baibu Tang, and its mechanism and material basis need further investigation.

Primary ciliary dyskinesia (PCD) is a congenital, motile ciliopathy with pleiotropic symptoms. Although nearly 50 causative genes have been identified, they only account for approximately 70% of definitive PCD cases. Dynein axonemal heavy chain 10 (DNAH10) encodes a subunit of the inner arm dynein heavy chain in motile cilia and sperm flagella. Based on the common axoneme structure of motile cilia and sperm flagella, DNAH10 variants are likely to cause PCD. Using exome sequencing, we identified a novel DNAH10 homozygous variant (c.589C > T, p.R197W) in a patient with PCD from a consanguineous family. The patient manifested sinusitis, bronchiectasis, situs inversus, and asthenoteratozoospermia. Immunostaining analysis showed the absence of DNAH10 and DNALI1 in the respiratory cilia, and transmission electron microscopy revealed strikingly disordered axoneme 9+2 architecture and inner dynein arm defects in the respiratory cilia and sperm flagella. Subsequently, animal models of Dnah10-knockin mice harboring missense variants and Dnah10-knockout mice recapitulated the phenotypes of PCD, including chronic respiratory infection, male infertility, and hydrocephalus. To the best of our knowledge, this study is the first to report DNAH10 deficiency related to PCD in human and mouse models, which suggests that DNAH10 recessive mutation is causative of PCD.
