ABSTRACT

OBJECTIVE To study the pharmacokinetics of paeoniflorin, hesperidin, naringenin, formononetin and enoxolone from Chitong xiaoyanling granules in rats. METHODS Six male SD rats fasted but not deprived of water for 12 h were given Chitong xiaoyanling granules (5.0 g/kg) intragastrically at one time. Blood was collected from inner canthus of rats at different time points after administration. Plasma samples were pretreated with acetonitrile precipitated protein (sulfamethoxazole as internal standard), and the concentrations of 5 ingredients in plasma were determined by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The pharmacokinetic parameters of each ingredient were calculated using DAS 3.0 software. RESULTS After intragastric administration of Chitong xiaoyanling granules, tmax and t1/2 of formononetin were the shortest among 5 ingredients (0.25 h and 0.39 h, respectively). For naringenin and enoxolone, the tmax was shorter, but t1/2 was longer, and there was an obvious double-peak phenomenon in the drug-time curve of naringenin. Compared with the other three components, cmax and AUC of paeoniflorin and hesperidin were not directly proportional to the content of in vitro components. CONCLUSIONS Formononetin, naringin and enoxolone in Chitong xiaoyanling granules were absorbed rapidly in rats, while paeoniflorin and hesperidin were absorbed slowly.

ABSTRACT

Objective To explore the development trend and influencing factors of major diseases of urban residents, and to construct a prediction model of _heart disease mortality. Methods One-way analysis of variance (Duncan's test at a=0.05) and correlation analysis were used to analyze the significant differences between the different categories of disease mortality and the correlation with the influencing factors. The exponential function was used to fit the relationship between the proportion of the elderly population and the death rate of heart disease at various stages, and the prediction model of heart disease mortality was constructed through the stepwise regression equation. Results The mortality rate of heart disease and cerebrovascular disease showed a rising trend. The incidence of the four major diseases in men was significantly higher than that in women (P2 > 98, P<0.01). Conclusion According to the results of the survey, the influencing factors of major diseases and the high-risk population should be focused on prevention and treatment. It is recommended that the prevention and treatment of heart disease is carried out for the aged 60+ and the prevention and treatment of cerebrovascular diseases is carried out for the aged 80.

ABSTRACT

ObjectiveTo investigate whether CD4+ CD25+ CD127dim/- regulatory T lymphocytes (Treg) can induce the proliferation of hepatic stellate cells (HSC) and expression of fibrosis-related factors on HSC in vitro and further to explore the mechanism of Treg inducing fibrogenesis. MethodsHSC LX-2 cells were subcultured.CD4+ CD25+ CD127dim/- cells were purified using magnetic cell separation. The HSC were co-cultured with Treg by direct contact or by Transwell system in vitro. The HSC cultured alone was used as control. Cell proliferation was measured by CCK-8 assay.The expression of transforming growth factor (TGF)-β1 was detected by enzyme-linked inmunosorbent assay (ELISA), and the expressions of hyaluronic acid (HA) and precollagen Ⅲ (PC Ⅲ ) were detected by radio immunoassay (RIA). The data were analyzed by LSD-t test. ResultsHSC proliferation was strongest when Treg∶ HSC= 1.5∶ 1. The absorbance in direct contact co-culture group and Transwell system co-culture group was (0. 713±0. 032) cpm and (0. 735±0. 028) cpm, respectively, both of which were higher than that in control group [(0. 677 ± 0. 029) cpm](t = 5. 4003 and 8. 7878,respectively; both P<0. 01). The concentrations of TGF-β1 in the supernatant were (781. 59 ±76.45) pg/mL and (813. 53±60. 62) pg/mL, respectively in direct contact co-culture group and Transwell system co-culture group, which were significantly higher than that in control group [(722.51±59. 66) pg/mL](t = 4.0014 and 6. 1653, respectively; both P<0.01).The concentrations of HA were (433. 575±27.90) ng/mL and (445.40±23.73) ng/mL, respectively in direct contact co-culture group and Transwell system co-culture group, which were higher compared to that in control group [-(415. 83±19.44) ng/mL](t =3. 3124 and 5. 5231, respectively; both P<0.01). Likewise, the concentrations of PCⅢ were (21. 93± 1.71) and (23. 125± 1.87) ng/mL in direct contact group and Transwell group, respectively compared to (20. 10± 1.49) ng/mL in control group (t = 4. 8082 and 7. 9436, respectively; both P < 0.01).Furthermore, the absorbance,concentrations of TGF-β1, HA and PC Ⅲ in Transwell co-culture group were all higher compared to direct contact group (t = 3. 3875, 2.1639, 2. 2107 and 3.1354, respectively; all P<0. 05).ConclusionsThe cell proliferation and the expressions of fibrosis-related factors in HSC increase greatly after co-cultured with CD4+ CD25+ CD127dim/-Treg. Therefore, Treg may play an important role in inducing liver fibrogenesis.

ABSTRACT

Stilbene glycoside (TSG) has been shown to have many beneficial properties. It is therefore essential to understand the absorption and metabolism of TSG in detail. We determined the recovery of TSG and its metabolites (TSG sulfate/glucuronides) in rat gastric contents, gastric mucosa, portal vein plasma, celiac arterial plasma, bile, and urine after administration of 15mg of TSG in 0.5mL physiological saline or incubation for 20min in situ in the stomach of rats. Within 20min, (64.0±9.8)% of the administered TSG disappeared from the stomach; later, TSG was recovered in both free and conjugated forms in plasma and bile, but not in urine. On the other hand, only free TSG was detected in the gastric contents and mucosa; it was also detected in the portal vein plasma as (48.1±3.5)% of the total TSG (all forms of TSG). However, the proportion of free TSG in the celiac arterial plasma and bile decreased to 4%-10%. In addition, the proportion of free TSG to total TSG in the liver microsome incubation mixture after TSG was incubated in liver microsome at 37℃ for 30min was very low [(10.6 ± 2.6)%]. These results indicate that TSG could be quickly absorbed from the rat stomach, conjugated in liver and excreted in bile. Such novel information would be helpful for the use of TSG as a beneficial natural product which may improve its proposed efficacy in preventing chronic diseases.

ABSTRACT

Objective To evaluate the prediction value of the early prediction score system of multiple organ dysfunction syndrome in the elderly (MODSE). Method A total of 393 patients with pulmonary infection, who were above60 years old, were divided into non MODSE(n =224) and MODSE group(n = 169) and were scored by the early prediction score system of MODSE. Independent-samples t Test was used to analyze the difference of forecast score between MODSE and non MODSE group. Receiver operating characteristic (ROC) curve was drawn,and the area under the curve was calculated. The prediction accuracy of scores for MODSE was assessed using sen-sitivity and specificity, and the optimal forecast point for MODSE was found. Results The score of MODSE group was higber than that of non MODSE[(19.38±12.049) vs. (45.78±20.257), P <0.001]. The area under the ROC curve was 0.889 (P <0.001) ond 95% (0.857~0.920). As the value of forecast score was 27.5, the sensitivity of the early prediction score system of MODSE was 82.8 %, the specificity of the early prediction score system of MODSE was 80.3 %. Conclusions The early prediction score system of MODSE is valuable in predic-tion of MODSE, which may be used to forecast MODSE and find the high risk population of MODSE.

ABSTRACT

Objective To investigate the preventive effect of midazolam pretreatment against neurotoxicity of ropivacaine and the underlying mechanism. Methods Thirty male SD rats aged 4-6 months weighing 250-300 g were randomly divided into 3 groups with 10 animals in each group: group Ⅰ blank control; group Ⅱ ropivacaine (R) and group Ⅲ midazolam-ropivacaine (M-R). In group R and M-R 0.75% ropivacaine was infused i.v. at a rate of 0.5 ml?min-1 until the animal developed convulsion. The animals were killed and brains were immediately removed for detennination of glutamate, aspartate, glycine and GABA content in the brain. Venous blood samples were taken for determination of pH and plasma concentration of lactate. The total amount of ropivacaine infused was calculated.Results The plasma lactate concentration was significantly higher and pH was significantly lower in group R than in blank control group. The concentrations of the 4 amino acids in the brain were significantly increased in group R and M-R as compared with the blank control group. The aspartate, glycine and GABA contents in the brain were significantly lower in M-R group than in R group. The total amount of ropivacaine infused i.v. was significant larger in group M-R than in group R.Conclusion Midazolam pretreatment can prevent the neurotoxicity of ropivacaine by modulating the balance between excitatory and inhibitory amino acids.
