OBJECTIVETo investigate the inhibitory effects of OMT on TGF-β1-induced CFBs proliferation, and then explore the mechanism.
METHODThe experiment was randomly divided into 6 groups as following: control group (serum free DMEM), model group (20 μg x L(-1) TGF-β1), OMT low dose group (1.89 x 10(-4) mol x L(-1) + 20 μg x L(-1) TGF-β1), OMT medium dose group (3.78 x 10(-4) mol x L(-1) + 20 μg x L(-1) TGF-β1), OMT high dose group (7.56 x 10(-4) mol x L(-1) + 20 μg x L(-1) TGF-β1), SB203580 group (p38MAPK blocking agent, 1 x 10(-5) mol x L(-1) + 20 μg x L(-1) TGF-β1). Vimentin of CFBs was identified by immunocytochemical methods, α-SMA of myFBs as well. Inhibitory effects of OMT on CFBs proliferation was detected by the MTT assay. Picric acid Sirius red staining was analyzed collagen type I and collagen type III deposition. Western blot was determined the expression of p38MAPK, p-p38MAPK, collagen type I and collagen type III.
RESULTMTT results showed that OMT significantly inhibited CFBs proliferation induced by TGF-β1 (P < 0.01) α-SMA immunocytochemical experiments suggested that OMT could protect against the CFBs proliferation. OMT could significantly decrease the deposition of collagen type I and collagen type III by Western bloting and picric acid Sirius red staining. Western blot results showed that TGF-β1 enhanced p38MAPK phosphorylation, however OMT attenuated the phosphorylation of p38MAPK induced by TGF-β1 (P < 0.01).
CONCLUSIONOMT can inhibit the CFBs proliferation induced by TGF-β1, and its mechanism may be involved in inhibiting p38MAPK phosphorylation.

Objective:To establish a method for preserving viral nucleic acids in plasma using a blood collection card based on the dry spot method,to predict the duration of nucleic acid preservation by establishing the Arrhenius equation,and to demonstrate the feasibility of this preservation method for the re-testing of nucleic acids in blood samples retained by blood banks.Methods:Plasma samples positive for HBV,HCV,and HIV nucleic acids were prepared into preservation cards in the form of dry plasma spots for storage.The prepared preservation cards were placed under accelerated storage conditions at 37,45,50,and 55 ℃.The preservation cards were periodically retrieved from each temperature condition for nucleic acid extraction,and the nucleic acid samples were purified for subsequent PCR testing,with the recorded CT values.An Arrhenius equation model was established between the expiration time and the storage temperature,thereby predicting the validity period of nucleic acid preservation in blood collection cards under specified storage temperature conditions.Results:For the plasma samples positive for HBV,HCV,and HIV nucleic acids preserved using the dry spot method,the regression equations for the duration with temperature were as follows:y=-11546x+31.74 for HBV,y=-12949x+36.88 for HCV,and y=-12204x+34.48 for HIV,with the correlation coefficient r greater than 0.98 for all.It was predicted that at a storage temperature of 4 ℃,the preservation periods for HBV,HCV,and HIV viral nucleic acids using the dry spot method would be 20792 days,19289 days,and 14285 days,respectively.At a storage temperature of 20 ℃,the preservation periods would be 2135 days 1502 days,and 1289 days,respectively.Conclusion:The nucleic acids of the three common viral pathogens in blood samples,when preserved using the dry spot method,conform to a first-order reaction pattern in the accelerated degradation experiment.The relationship between the rate of nucleic acid degradation and the absolute temperature of storage is consistent with the Arrhenius equation.Based on the calculations using this equation,the stability and validity period of plasma nucleic acid samples preserved using the dry spot method can reach a minimum of 3 .5 years under storage conditions not exceeding 20 ℃,which essentially meets the requirements for the preservation period of blood samples retained by blood banks.

OBJECTIVETo study the role of non-nutritive sucking in preterm infants requiring mechanical ventilation therapy.
METHODSIn a study of 68 preterm infants requiring mechanical ventilation, a randomly selected observation group of 35 infants was provided with non-nutritive sucking and a control group of 33 infants was not. The time to reach full enteral feeding, birth weight recovery time, body weight growth rate, hospitalization time, feeding tolerance and mechanical ventilation-related complications were compared between the two groups.
RESULTSThe time to reach full enteral feeding and hospitalization time were shorter (P<0.01), the incidence of feeding intolerance was lower (P<0.05), and the body weight growth rate was higher (P<0.05) in the observation group than in the control group. There were no significant differences in the birth weight recovery time and the incidence of mechanical ventilation-related complications between the two groups.
CONCLUSIONSThe use of non-nutritive sucking can increase growth rate, shorten hospitalization time and improve feeding tolerance in preterm infants requiring mechanical ventilation therapy. Moreover, it does not result in an increase in mechanical ventilation-related complications.

OBJECTIVETo summarize the clinical features of idiopathic premature ovarian failure (POF) and explore the early diagnosis and intervention.
METHODSA retrospective study was conducted in 39 women with idiopathic POF treated between February, 2009 and January, 2010. The clinical data of the patients including the menstrual feature, POF incidence, vaginal ultrasound and pregnancy outcomes were investigated.
RESULTSOne patient had primary amenorrhea and 38 had secondary amenorrhea with an average duration of amenorrhea of 5.82 years. Abrupt cessation occurred after 1-2 menstruations following the menarche in 2 cases (5.1%) and without identifiable preceding signs in 9 cases (23%). The mean uterine and ovarian volume was significantly smaller in POF group than in the control group. Antral follicle count (AFC) was also significantly lower in POF group. Vaginal ultrasound detected at least one ovary in 89.7% and follicular activity in 79.5% of the POF patients. Evidence of ovulation was found in 12 patients, and spontaneous pregnancy occurred in 2 patients with a pregnancy rate of 5.1%.
CONCLUSIONPatients with menstrual disturbance, polymenorrhea and oligomenorrhea are at risk of developing POF, in which case regular detection of the mean uterine volume, ovarian volume and AFC by vaginal ultrasound may help in early POF detection. Close monitoring can be necessary in the course of hormone replacement therapy, and timely intervention with assisted reproductive techniques may increase the chance of pregnancy.
