ve To determine the most approprite hypoxic concentration and duration for prenatal hypoxic adaptation animal experiment by exposing pregnant rats to the hypoxic air of different oxygen concentration.Methods Full-term pregnant rats( gestation time 22 days) were placed in an airtight cabin specially designed for hypoxic adaptation experiment. The rats were divided into 7 groups. The Q2 concentration in the airtight cabin was decreased from 21% (group Ⅰ as control) to 18% (group Ⅱ), 17% (group Ⅲ), 16% (group Ⅳ), 15% (group Ⅴ), 14% (group Ⅵ) and 13% (group Ⅶ) respectively. The animals were exposed to short duration of hypoxic air twice with a break of 5min breathing fresh air. The duration of the first hypoxic episode lasted 10 min (group Ⅰ ) , 5 min (group Ⅱ), 7.5min (group Ⅲ), 9.83 min (group Ⅳ), 11.5 min (group Ⅴ), 13.17 min (group Ⅵ) and 14 min (group Ⅶ) respectively. The second hypoxic episode lasted 10min, 9.33 min, 11 min, 15.17 min, 13.33 min, 17 min and 18 min respectively. Ten newborn rats (1 day after birth) randomly selected from each group were placed in a 100ml airtight bottle and the duration from the start to the time when the newborn rat stopped breathing was recorded as hypoxia surviving time. Another 10 newborn rats randomly selected from each group were decapitated and brain was removed for light and electron microscopic examination to determine the degree of neuronal damages. Results In group Ⅰ-Ⅴ the newborn rats were normal (pink skin color and good extremity movement) . In group VI 10/55 (18%) newborn rats were cyanotic with diminished extremity movement, the others were normal. In group VIII 11/52(21% ) newborn rats died, 14/ 52(27%) were cyanotic with diminished extremity movement. Neuronal damages could be seen in cyanoticnewborn rats including decreased number, swelling, apoptosis of neurons and expanded mitochondria. The hypoxia surviving time was significantly longer in group Ⅳ, Ⅴ and Ⅵ than that in control group. Conclusions Hypoxic air containing 15% O2 is appropriate for animal experiment of prenatal hypoxic adaptation. It is better to divide prenatal hypoxia into two episodes lasting 11.5 min and 13.33 min with a break of 5 min between them when animals breathe fresh air.

BACKGROUND:Chronic hepatitis B virus infection can impact the biological characteristics of bone marrow mesenchymal stem cel s. Adipose-derived mesenchymal stem cel s have gained more and more attention due to their high safety, little invasiveness, easy purification and rapid proliferation. OBJECTIVE:To establish the isolation and culture method of adipose-derived mesenchymal stem cel s from patients with hepatitis B virus infection in vitro, and to observe the biological characteristics of cel s. METHODS:Adipose-derived mesenchymal stem cel s were isolated from the subcutaneous fat of hepatitis B virus infection patients by col agenase digestion and adherent method. Growth curve of adipose-derived mesenchymal stem cel s were detected by MTT method and cel phenotypes were detected by flow cytometry. The adipogenic and osteogenic differentiation potential of adipose-derived mesenchymal stem cel s were detected in vitro. RESULTS AND CONCLUSION:(1) Adipose-derived mesenchymal stem cel s from 10 patients with hepatitis B virus infection were al isolated and cultured successful y. The primary passage time of adipose-derived mesenchymal stem cel s was (8.3±1.2) days. The growth curve of cel s was“S”shaped. Cel s came into a logarithmic phase at days 3-4, and came into platform at day 7. (3) Passage 3 adipose-derived mesenchymal stem cel s highly expressed CD29, CD166, HLA-ABC and CD44, but did not express or lowly expressed CD34 and HLA-DR. (3) Adipose-derived mesenchymal stem cel s differentiated into adipocytes after adipogenic induction, and differentiated cel s were positive for oil red O staining;after osteogenic induction, adipose-derived mesenchymal stem cel s differentiated into osteoblasts that were positive for alkaline phosphatase staining. These findings indicate that the col agenase digestion and adherent method can be used to effectively isolate adipose-derived mesenchymal stem cel s from patients with hepatitis B virus infection, and the cel proliferation is rapid so that a large number of cel s can be obtained in the short term.
