Objective To address angiotensin Ⅱ type 1 receptor (AT 1R) gene polymorphism and its relationship with plasma endothelin (ET) in PIH. Methods Gene polymorphism of AT 1R at site 1166 was detected with polymerase chain reaction (PCR), digestion of restriction enzyme and electrophoresis. Plasma ET was measured by radioimmunoassay. Results 1. The frequencies of genotype(AC and CC) at 1166 of AT 1R gene and C allele in PIH individuals were significantly higher than those of control group, (? 2=11.06, 9.73, respectively, P0.05). Conclusions 1. The variant (A→C) of 1166 polymorphism site of AT 1R is associated with the generation of PIH, and C allele may be a susceptible gene to PIH. 2.There is relationship between AT 1R gene and plasma ET level in PIH patients.

Objective To investigate the relationship between hepatocyte growth factor (HGF) and vascular endothelial cells (VEC) in pregnancy induced hypertension (PIH) Methods Twenty women with PIH (6 mild, and 14 moderate or severe PIH ) and 20 women with normal pregnancy were recruited as study group and control group, respectively The two groups were matched in maternal age, parity and gestational age Flow cytometer was used for counting the number of peripheral blood circulating endothelial cells (CEC), while enzyme linked immunoadsordent assay (ELISA) was used to measure the concentration of serum HGF Results In the study group, the concentration of HGF was (1395?512) ng/L, and the number of CEC was (109 360?24 070) /L In the control group, the concentration of HGF was (1565 ?399) ng/L, and the number of CEC was (21 800?4420)/L The differences both in the concentration of HGF and the number of CEC between the two groups were statistically significant ( P

Objective:To establish the quality control methods for Xinmeng Anshen granule. Methods:TLC was used to identify Salviae Miltiorrhizae Radix Et Rhizoma,Mori Fructus, Ziziphi Spinosae Semen( fried) ,Arachis Hypogaea L. and Schisandrae Chinensis Fructus in the granules. HPLC was used to determine the content of protocatechuic aldehyde in Salviae Miltiorrhizae Radix Et Rhizoma and spinosin in Ziziphi Spinosae Semen. Results:The TLC spots were clear and well-separated without any interference from the nega-tive sample. The calibration curves were linear within the range of 3.972-198.600 μg·ml-1(r=0.999 9) for protocatechuic alde-hyde and 7. 070-226. 240 μg·ml-1(r=0. 999 9) for spinosin. The average recovery was 98. 46% (RSD=1. 18%, n=9) for proto-catechuic aldehyde and 98. 20% (RSD=0. 90%, n=9) for spinosin. Conclusion:The established quality control methods are accu-rate, simple, repeatable and specific. It can be well used for the quality control of Xinmeng Anshen granule.

AIM: To study the changes of neurokinin A (NKA) and NKA mRNA in lung tissues of asthmatic guinea pigs exposed to chronic cigarette smoke and investigate the mechanism. METHODS: The model of asthma in guinea pigs was made by exposure to aerosolized ovalbumin and animals were randomly assigned into: ① inhale cigarette smoke (ICS) 2 weeks before provoked; ② ICS 2 weeks after provoked; ③ 2 weeks after provoked (no-ICS); ④ asthma (no-ICS before provoked); ⑤ normal control. The contents of NKA in lung tissues were detected by ELISA and NKA mRNA expression was detected by reverse transcription-polymerase chain reaction. RESULTS: ① The levels of NKA and NKA mRNA expression in lung tissues of asthma group were significantly higher than those in normal control group (P

Objective:Our purpose was to investigate the function of angiotensis converting enzyme(ACE) in the occurrence and development of pregnancy-induced hypertension(PIH). Methods:The study group included 30 pregnant women diagnosed with PIH( 10 mild, 10 moderate, 10 severe). Thirty healthy pregnant women were selected as the control group. The serum was assayed for the activity of ACE by using color comparison method, hippuric acid used as the substrate. Results:The activity of ACE of the study group was significantly higher than that of the control group. Significantly positive correlationships existed between mean blood pressure, degree of adema, level of urine protein,and uric acid. Conclusion:The elevation of serum activity of ACE is related to the occurrence and development of PIH.

A UPLC method has been developed in the current investigation for simultaneous determination of nine chemical markers of Bletilla striata, 4-hydroxymethylphenyl beta-D-glucoside, blestroside, dactylorhin A, militarine, dihydrophenanthrene 5, gymnoside V, dihydrophenanthrene 1, benzylphenanthrene 3 and gymnosides IX. Separation was performed at 45 degrees C on an ACQUITY UPLC BEH C18 column (2.1 mm x 150 mm, 1.7 microm) with a gradient solvent system of acetonitrile-water as the mobile phase. The flow rate was 0.3 mL x min(-1), the detection wavelength was 280 nm. The results showed that the nine chemical markers could be well resolved and that in the selected linear range, all calibration curves of the nine chemical markers showed good linearity (r > or = 0.999 3). The recoveries (n = 6) were in the range of 98.15% - 102.2% and RSDs were between 2.1% - 3.6%. The data suggested that the developed UPLC-UV method had good reproducibility, robustness, and accuracy, which was suitable for the quality control of Bletilla striata. Applications of the method showed that the nine chemical markers had higher contents in the wild B. striata than in the cultivated ones.

Objective To explore hemodynamic parameter changes in pulmonary arterial hypertension(PAH)treated by transplantation of bone marrow mesenchymal stem cells(MMSCs)in the experimental rats.Methods MMSCs cells were collected from bone marrow of Sprague-Dawleye(SD)rat's femoral and tibial bones,cultured and passaged in vitro,then stained by Hoechst 33342 fluorescence dye stuff.Ninety healthy male SD rats were randomly divided into 3 groups(n=30):normal control group(group N),MMSCs transplanted group(group M),PAH model group(group H).The rats in the two latter groups were given a single subcutaneous crotaline(50 mg/kg)to establish the model of PAH.The rats of group N were injected respectively a single subcutaneous 9 g/L saline water(6 mL/kg).After 21 days,5?109 L-1 MMSCs cultured in 1 mL phosphate-buffered saline were infused into the rats respectively in group M by sublingual vein and 1 mL L-DMEM was given in group H.The indexalso of right ventricle systolic pressure(RVSP),right ventricle hypertrophy index,arterial blood gas analysis and the changes of small pulmonary blood vessel were observed after 28 days.Results The administration of MMSCs 28 days after PAH nearly completely prevented the increase in RVSP with PAH alone [(32.20?2.32)mmHg vs(48.30?1.56)mmHg P
