[Clinical analysis of 5 cases of acute poisoning by inhalation of hydrochlogen chloride].

Objective: To analyze the clinical characteristics caused by acute poisoning by inhalation of hydrogen chloride (HCl) and to raise awareness and treatment level of the disease. Methods: The clinical manifestations, imaging features, diagnosis, treatment and prognosis of 5 patients with acute HCl poisoning were analyzed retrospectively. Results: Among the 5 cases of HCl poisoning, 2 cases were severe poisoning, 3 cases were moderate poisoning. All patients were treated with corticosteroids and symptomatic treatment, one of them was treated with venovenous extracorporeal membrane oxygenation (VV-ECMO) . All patients were recovered and discharged from hospital. Conclusion: The lung damage of acute poisoning by inhalation of HCl is rapidly progressing, early detection and timely medical treatment can obtain a better prognosis.

Crossbreeding of Phyllostachys species (Poaceae) and identification of their hybrids using ISSR markers.

Crossbreeding is an efficient means to increase production and quality in plants; however, hybridization is seldom reported in bamboo. We crossbred two bamboo species Phyllostachys kwangsiensis (female parent) and Phyllostachys bambusoides (male parent) for the first time, and obtained suspected bamboo hybrids. We identified two bamboo hybrids from the above parents using PCR/ISSR. We concluded that ISSR markers are useful to identify bamboo hybrids, and that breeding between bamboo species is possible and useful.

Overexpression of forkhead box protein M1 (FOXM1) plays a critical role in colorectal cancer.

BACKGROUND: The forkhead box M1 (FOXM1), an important regulator of cell differentiation and proliferation, is overexpressed in a number of aggressive human carcinomas. However, the clinical significance of FOXM1 signaling in human colorectal cancer (CRC) pathogenesis remains unknown. The aim of this study was to evaluate the role of FOXM1 in CRC tumorigenesis. METHODS: We investigated FOXM1 expression in 103 cases of primary CRC and matched normal tissue specimens and explored the underlying mechanisms of altered FOXM1 expression and the impact of this altered expression on CRC proliferation and metastasis using in vitro models of CRC. RESULTS: The results showed that high expression of FOXM1 staining was 85.44% (88/103) in 103 cases of CRC and 20.39% (21/103) in 103 cases of adjacent non-cancerous tissue samples; the difference of FOXM1 expression between two groups was statistically significant (P < 0.001). Silencing of FOXM1 inhibited the proliferation of CRC cells, and the invasion and migration of CRC cells were distinctly suppressed. Furthermore, FOXM1 knockdown led to substantial reductions in VEGF-A levels in CRC cell lines. CONCLUSIONS: Our data suggest that the pathogenesis of CRC maybe mediated by FOXM1, and FOXM1 could represent selective targets for the molecularly targeted treatments of CRC.
