This paper is to report our results of the observation on the changes of the pulmonary water content of the rats and mice after their exposure to a simulated altitude of 6000 meters above sea level for seven days.It was found that the changes of the pulmonary water content varied with the duration of exposing to the high altitude. It was lower than the control value on the first day of exposure, and then it increased approaching or even being a little higher than the control value on the second and third day. But it decreased and was below the control value again from the fourth day to the seventh day. The lung weight was increasing continuously in the same period.In addition, there were progressive increase of both the wet-lung/body and dry-lung/body indices, progressive decrease of left/right ventricles ratio, and gradual rising of hemoglobin in the animals studied.

Rats were made to bleed and about 40% of the total blood volume was lost. A replacement of Ringer's solution of the volume four times the lost blood volume was given and the animals were closely monitored for 24 hours. The hemoglobin level of the animals was low throughout the course of observation. The plasma colloid osmotic pressure reached the lowest point 15 minutes after bleeding, and then gradually rising up returned to a level about 90% of the control value at the end of 24 hours. The relativity between the plasma colloid osmotic pressure and the lung water content was quite significant in those rats in a low altitude environment (P0.05).The result indicates that the increased lung water content due to decreased plasma osmotic pressure could not be made further worse by hypoxia due to high altitude. The characteristic pulmonary hemodynamic changSs caused by hypoxia might be considered as the explanation of the phenomenon.

Objective To evaluate the effectiveness of suberselective uterine arterial embolization for uterine fibroids.Methods Uterine arterial embolization with golyvimylalcohol(PVA) particles or Iodized oil and Gelfoam or Pingyangmycin lipiodol and Gelfoam was performed in 182 patients with uterine fibroids.Results Bilateral and unilateral superselective uterine arterial embolization were performed in 173 cases and 9 cases respectively. 6~28 months (mean 11 months) after the procedure, complete disappearance of tumor(16 cases), an average shinkage of 67% in tumor volume(152 cases) and a mean 42% reduction of uterine volume were obtained in 168 followed-up cases. The clinical symptoms were relieved significantly.The main side effets were hypogastic pain(135/182).Conclusion Superselection uterine arterial embolization is an effective and microinvasive method in treating uterine fibroids.

To investigate the role of distribution and phylogeny of phenylethanoid glycoside in medicinal plants of Gesneriaceae, five phenylpropanoid glycosides, acteoside, paraboside B, isonuomioside A, paraboside II, and paraboside III were quantitatively determined in 12 species of Gesneriaceae by HPLC. The existence and content of these compounds were analyzed. The results showed that phenylethanoid glycosides were found in the most of those plants, but the kind of phenylethanoid glycosides varied in different species. Acteoside distribute in most of this plant group, paraboside B, isonuomioside A, paraboside II, and paraboside III were rare in those plants. The results of this study support morphological viewpoint that Trib. Trichosporeae is more developmental than Trib. Didymocarpeae.

S801 leukemic cell line established by our department was used as cells for interferon (IFN) induction and stimulating induction. S801 cell culture of concentration of 5-8x10~6 cells/ml was used for IFN induction and IFN titer of 3.55 Lg IU/ml was obtained by classical procedure. The IFN titer obtained S801 cell cultures after pretreatment with Ciwujia eleutherosides B. D and E or polysaccharide (PES) combined with priming procedure,then using Sendai Virus as an inducer was 10-20 times higher than that in cultures without any pretreatment. These Chinese medical herbs may be the ideal IFN helpinducers. This cell line may be applied for IFN production.

Objective To study adrenomedullin (AM) mRNA and protein expression level in myocardium of autoimmune myocarditis animal models induced by immunization of mice with lactobacillus casei cell wall element(LCWE). Methods Forty-five Balb/c male mice were randomly divided into experimental group (n = 30) and control group (n = 15), which were intraperitoneally injected with LCWE and phosphate buffered solution(PBS) at day 0,3,5 and 10,respectively. Sera and myocardium samples were gained 14,21 and 28 days after the first immunization. AM expression levels were determined by semiquantitative reverse transcriptase-polymerase chain reaction(RT- PCR) and immunchistochemistry,and mycardial histopathological lesions were observed. The anti- myosin antibodies in different stages were examined by an ELISA. Results There were myocardial necrosis or inflammatory infiltration in the experimental group, but myocardial lesions were not found in the control group. Anti - myosin antibodies were detected in sera of experimental mice,but not in control group. Immunchistochemistry findings demonstrated that AM expression level was higher in the experimental group than in the control group( P

OBJECTIVETo investigate the role of inhibitor of DNA binding-1 (Id-1) gene in adenoid cystic carcinoma cell growth and invasion behavior.
METHODSWith salivary adenoid cystic carcinoma cell lines ACC-M and ACC-2, dedected Id-1 gene expression was screened with immunofluorescence assay. After Id-1 mRNA knocking-down using small interfering RNA, RT-PCR and Western blot were used to detect the different expressions before and after interference, and the growth of cells before and after interference was deceted using the MTT assay, and the cell invasion ability was checked with the use of Transwell chamber assay.
RESULTSId-1 were both expressed in the ACC-M and ACC-2, and the expression in ACC-M was higher than that in ACC-2. After Id-1 RNA interference, the growth and invasiveness of ACC-M and ACC-2 were inhibited with the restrained degree in ACC-M much stronger than that in the ACC-2.
CONCLUSIONIn view of the important role of Id-1 in the behavior of growth and invasion in ACC cell, interfering the expression of Id-1 gene is expected to be a novel and effective means for the treatment of adenoid cystic carcinoma.

Modern drying technology was used to explore suitable drying process to provide scientific basis for improving drying processing methods of Scrophulariae Radix. Controlled temperature and humidity drying, vacuum drying apparatus, microwave vacuum drying apparatus, short infrared drying device were used to gain samples for analyzing. The character appearance, concentration of main components and power consumption indicators were chosen for preliminary judging. Six major components, including iridoids and phenylpropanoids were analyzed by UPLC-MS/MS method. The contents of polysaccharides were determined by UV-visible spectrophotometry. The character appearance with controlled temperature and humidity drying and short infrared drying meet the pharmacopoeia standard (Ch. p, edition 2015), while samples with vacuum and microwave vacuum drying apparatus didn't. Compared to fresh sample, concentrations of harpagide, harpagoside, aucubin and catalpol were lower in the dried samples. Angoroside-C showed no significant change before and after drying. Concentration of acteoside increased after drying. Samples with controlled temperature (70 degrees C) and humidity (15% - 10%) drying had high content and short drying time. The better drying process of Scrophulariae Radix was controlled temperature and humidity drying. The method will provide the reference for the drying technology standard of roots medicine.
