According to the requirements of ptobiotics, we have separated 13 strains of Lactobacillus from the content in gut of lactating piglet. Among them 3strains are L. acidophilus, one is L. casei, one is L. atenaforme and 8 strains are L. fermentum. They can resist 1.0% bile salt and the acidity of pH3.0, can inhibit pathogenic Escherichia coli and Staphylococcus aureus. They are safe and non-toxic to mice.

Objective To summarize the experience in the treatment of Marfan syndrome of pregnancy complicated with acute type A aortic dissection.Methods Three women with Marfan syndrome of pregnancy complicated with acute type A aortic dissection were treated.The average age was 28.6 (25-31) years,and the average gestational age was 36.5 (32-38) weeks.At first caesarean operation were performed under general anesthesia.Bentall + Sun' s operation was performed under deep hypothermic circulatory.After operation,the mother and fetus were followed up.Results Three women and their fetus were safe.The average extracorporeal circulation time,aorta clamp time and circulatory arrest time were 265 (210-280) min,135 (120-160) min and 26.5 (20-29) min,respectively.After a mean follow-up of 2.0 (1.0-2.5) years,3 patients were living well.CT angiogram detected normal aortic,with no signs of distal dilation.Three fetus were normal in development and neurocognitive function.Conclusion Methods of surgical repair and fetal delivery should be chosen based on aortic pathological changes and gestational age to maximize the safety of the mother and fetus.

Objective To explore the influence of obstructive sleep apnea hypopnea syndrome(OSAHS)in children on the secretion of antidiuretic hormone(ADH). Methods Thirty pediatric patients with OSAHS were examined with polysomnography(PSG) and urinary volume was recorded during sleep,and vein blood was sampled in deep sleep to detect the level of ADH in serum using radioimmunoassay technique,which were performed before and after adenotonsillectomy. Among twenty heath children were also detected the secretion of ADH as normal controls. Results After surgery, apnea-hypopnea index(AHI)decreased(from 17.4±2.6 to 3.3 ±1.4,t=27.68,P＜0.001),lowest SaO2 increased(from 0.783 ±0.134 to 0.954 ±0.062, t=6.45, P＜0.001). The level of ADH in OSAHS patients(63.1±35.2)ng/L was much lower than that in health children(85.1±22.2)ng/L(t=2.75,P＜0.01).The serum ADH level in postoperative patients(83.1±21.2)ng/L was increased significantly compared with that of preoperative(t=2.56, P＜0.05), and no statistical difference versus that of health children(t=0.17, P＞0.05). Nycturia volume of preoperative OSAHS children(492±90)ml was significant higher than that of postoperative(332±56)ml or normal controls(346±62)ml(t was 7.85 and 6.43,both P＜0.001). There was no significance in nycturia volume between postoperative group and control group(t=0.77,P＞0.05). Conclusions After adenotonsillectomy in children with OSAHS caused by adenotonsillan hypertrophy. The sleep pattern and ADH secretion could become normal.

OBJECTIVETo observe the pathological changes and the expression of tumor necrosis factor alpha (TNF-alpha) and transforming growth factor beta (TGF-beta) in lung tissue of rats with radiation injury for exploring the mechanism of blood-activating and stasis-dissipating drugs in radiation injury prevention and treatment.

METHODSOne hundred and thirty SD female rats were randomly allocated into the simple irradiation group (n=60), the TCM herbs treatment group (n=60) and the blank control group (n=10). The right lung of all rats except those in the blank control group were irradiated by linear accelerator, 3 Gy each time, twice weekly, the maximum accumulated dose being 30 Gy. Ten rats in the two groups were randomly sacrificed at each of the 6 time points (1, 3, 5, 8, 12 and 26 weeks after repeated irradiation), their lung was harvested out, sliced and dyed with HE stain. The histological changes, levels of TNF-alpha and TGF-beta expression in the lung tissue were then observed by immunohistochemical technique.

RESULTSThe most serious acute radiation pneumonia was seen in the 5th week and pulmonary fibrosis was remarkable in the 26th week in the simple irradiation group, with the expressions of TNF-alpha and TGF-beta at different time phases enhanced significantly (P < 0.01). While in the TCM herbs treatment group, the pneumonia was milder, pulmonary fibrosis in late stage was not so obvious, and the expressions of TNF-alpha and TGF-beta significantly lower than those in the simple irradiation group (P < 0.01).

CONCLUSIONBlood-activating and stasis-dissipating drugs can inhibit expression of inflammation-inducing factors and fibrosis-inducing factors to lessen the inflammatory reaction of early radiation pneumonia, prolong the progression of radiation lung fibrosis, showing preventive and treating action on radiation lung injury.

OBJECTIVETo explore the effect of Salvianolate on myosin heavy chain (MHC) in cardiomyocytes of congestive heart failure (CHF) rats.

METHODSSixty male SD rats were divided into 6 groups according to random digit table, i.e., the normal control group (NCG), the model group, the Captopril group (CAG), the low dose Salvianolate group (LSG), the high dose Salvianolate group (HSG), the Captopril and high dose Salvianolate group (CSG), 10 in each group. CHF rat model was established with peritoneal injection of adriamycin in all rats except those in the NCG. Equal volume of normal saline was peritoneally injected to rats in the NCG, once per week for 6 successive weeks. Corresponding medication was started from the 5th week of injecting adriamycin. Rats in the CAG were administered with Captopril solution at the daily dose of 10 mg/kg by gastrogavage. Rats in the LSG and the HSG were administered with Salvianolate solution at the daily dose of 24.219 mg/kg and 48.438 mg/kg respectively by gastrogavage. Salvianolate was dissolved in 2 mL 5% glucose solution and administered by peritoneal injection. Rats in the CSG were peritoneally injected with high dose Salvianolate solution and administered with Captopril solution by gastrogavage. Two mL normal saline was peritoneally injected to rats in the model group, once per day for 8 successive weeks. Eight weeks later, the cardiac function and myocardial hypertrophy indices were detected by biological signal collecting and processing system. mRNA expression levels of alpha-MHC and beta-MHC in cardiac muscle were detected by fluorescence quantitative PCR. Expressions of protein kinase C (PKC) in cardiac muscle were detected by Western blot.

RESULTSCompared with the normal control group, heart mass index (HMI) and left ventricular mass index (LVMI) obviously increased in the model group (P < 0.01). Compared with the model group, HMI and LVMI decreased in HSG, CAG, and CSG groups (P < 0.05, P < 0.01). It was more obviously lowered in the CSG group than in the CAG group (P < 0.05). Compared with the NCG, the mRNA expression level of alpha-MHC in cardiac muscle decreased, the mRNA expression level of p-MHC and the expression of PKC in cardiac muscle increased in the model group (P < 0.01). Compared with the model group, the mRNA expression level of alpha-MHC in cardiac muscle was increased, and the mRNA expression level of beta-MHC and the expression of PKC in cardiac muscle were decreased in HSG, CAG, and CSG groups (P < 0.05, P < 0.01). There was statistical difference between the CSG group and the CAG group (P < 0.05).

CONCLUSIONSSalvianolate could up-regulate the mRNA expression level of alpha-MHC, and down-regulate the mRNA expression level of beta-MHC in cardiac muscle. Its mechanism might be related to decreasing the expression of PKC.
