AIM: To elucidate the regulation of Shenqiwan on the altered expression and mRNA level of AQP2.METHODS: 30 normal male adult SD rats were stochastically allocated into 3 groups, respectively administrated with distilled water (the control group), low dose of Shenqiwan (1.5 g/kg) and high dose of Shenqiwan (3.0 g/kg), consecutively for 7 days. Rat serum containing constituents from Shenqiwan was prepared by cardiac blood sampling followed by centrifugation. Cell survival rates were analyzed by MTT assay for the appropriate dilution factor of medicated serum after 24 h exposure. Indirect immunofluorescence labeling visualized the distribution of AQP2. The expression of AQP2 was determined by Western blot and the mRNA level of AQP2 was detected by semi-quantitative RT-PCR.RESULTS: Both low dose of Shenqiwan medicated serum (at 50% concentration) and high dose (at 25% concentration) significantly up-regulate the expression of AQP2 (P<0.01) in comparison with the normal rat serum. Specifically high dose of Shenqiwan at 25% concentration further increases the expression of AQP2 (P<0.05). In addition, these two groups mentioned above obviously elevates the mRNA level of AQP2 (P<0.05).CONCLUSION: Shenqiwan-containing medicated serum may function in the genetic transcription and protein translation, hoisting up the gene and protein level of AQP2, which indicates Shenqiwan associated with the regulation of aquaporin for water metabolism.

AIM: To investigate the changes of neuroapoptosis in brain and learning ability after neonatal mice exposed to inhaled sevoflurane or isoflurane.METHODS: Ninety postnatal day(P)7 Wistar rats were randomly divided into 5 groups : group A sham anesthesia,group B 3.6% sevoflurane for 2 h, group C 3.6% sevoflurane for 6 h, group D 2.3% isoflurane for 2 h and group E 2.3% isoflurane for 6 h. Animals from each group were perfused transcardially with 0.1 mol phosphate buffer containing 4% paraformaldehyde 6 h after the end of anesthesia, and then the brains were exposed for immunohisochemistry, caspase-3 positive cells were detected. Behavioral studies with Morris water maze test were performed separately when the rats were 5-week-old and 14-week-old.RESULTS: The amounts of caspase-3 positive cells in the rats brain of Group B, C,D and E were greater than that in Group A, and the amount in group C was greater than that in gourp B, in group E more than that in group B(P<0.05). When face the spatial reference memory task or space exploration task, rats from different groups make it uniformly. Anesthetic rats and control rats performed similarly in terms of path length when learning to swim to the platform during locating trials. No rats showed significantly higher levels of retention during the probe trials in terms of target quadrant time, platform crossings and platform location time(P>0.05),but the number of platform crossings in group B,C,D and E was significantly higher than that in gourp A(P<0.05).CONCLUSION: Exposure to the concentration of 3.6% sevoflurane or 2.3% isoflurane could cause brain cell apoptosis of newborn rats. Isoflurane could cause more insults to brain than sevoflurane at an equivalent concentration. The memory ability to pessimal stimulation is decreased as the anesthesia mice 5 weeks old, such changes recede along with the growth of rats. Exposure to sevoflurane and isoflurane does not affect the spatial reference memory of newborn rat during their growth.

And to evaluate the function of transporters in sandwich-cultured rat hepatocytes (SCRH) using DPDPE as the probe substrate.METHODS: Co-incubate DPDPE with SCRH treated by alpha-naphthylisothiocyanate, the model compound, and measure the accumulation and the efflux of DPDPE by SCRH. The concentration of DPDPE in hepatocytes or Hank's buffer was determined by LC/MS/MS.RESULTS: DPDPE had a good linearity from 0.5 to 50 ng/mL (r²=0.9995) in Hank's buffer and from 0.1 to 5 ng/well (r²=0.9997) in hepatocytes in the LC/MS/MS method established in this study. This method was sensitive enough to quantify DPDPE used as probe substrate in SCRH transport studies. The inter- and intra-day precision (RSD) were less than 15% and the recoveries were above 65%. The basolateral uptake and canalicular efflux of DPDPE by SCRH was inhibited by ANIT without change in the basolateral efflux.CONCLUSION: The analytical method established here is selective, sensitive and feasible to determine DPDPE used as probe substrate in the evaluation of membrane transporters in SCRH.

AIM: To evaluate the predictive value of gene expression of ribonucleotide reductase M1 (RRM1) and excision repair cross-complementation 1( ERCCl ) in peripheral blood from Chinese patients with non-small-cell lung cancer (NSCLC) treated with gemcitabine plus platinum.METHODS: SYBR real-time PCR was used to determine the tumor tissue and peripheral blood RRM1 and ERCC1 mRNA expression levels in NSCLC patients. The χ² test was used to analyze categorical variables and Spearman rank correlation analysis was used to analyze continuous variables. Kaplan-Meier survival curves and the log-rank test were used for the comparison of overall survival rates.RESULTS: In the present study, 34 Chinese patients with histologically confirmed stages IIIB and IV NSCLC were recruited; the tumor tissue and peripheral blood gene expression levels were measured in 22 patients. Linear correlations were observed between peripheral blood and tumor tissue expression levels for RRM1 (R²=0.045, P=0.048), while no correlation was detected for ERCC1 (R²=0.016, P=0.251). Subjects with low peripheral blood RRM1 expression survived longer than those with high RRM1 expression (16.0 vs12.5 months, log-rank 3.980, P=0.046). The expression of ERCC1 showed no obvious differences between the two groups.CONCLUSION: The study demonstrates increased survival and superior efficacy of gemcitabine and cisplatin combination chemotherapy in the treatment of NSCLC patients with low peripheral blood RRM1 expression. The results contribute to the selection of patients who are most suitable for treatment with gemcitabine and cisplatin combination chemotherapy.

AIM: To investigate the impact of dopamine and norepinephrine on sublingual microcirculation of the septic shock.METHODS: Thirty-four patients with septic shock,were randomly divided into two groups. One group accepted dopamine (the dopamine group, DA)and the other accepted norepinephrine(the norepinephrine group, NE) to maintain mean blood pressure between 65 mm Hg to 75 mm Hg in one hour, and then the medicine dose of both groups was added to maintain mean blood pressure between 75 mm Hg to 85 mm Hg.Sublingual microcirculation was evaluated by sidestream dark field (SDF) imaging before and after the therapy. The 28-day mortality and the number of new arrhythmia was recorded.RESULTS: The 28 days mortality of the DA group and NE group was 47.06% and 52.94%, which had no significant difference (P>0.05). The new arrhythmia of the two groups had no significant difference(P>0.05). Compared with the base line, PVD after dopamine or norepinephrine therapy was higher both in DA group and NE group(P＜0.05),but the Lac,ScvO₂,PPV,MFI had no difference(P>0.05). The Lac,ScvO₂,PVD,PPV,MFI of the two different MAP levels had no significant difference in both groups(P>0.05).CONCLUSION: Both dopamine and norepinephrine can improve the MAP and the sublingual microcirculatory dysfunction in septic shock, and these impacts do not change with the dose of dopamine and norepinephrine or the level of MAP.

TRALI is one type of new-onset acute lung injury that happens within 6 h of initiation of any blood transfusion. It is one of the most common causes of transfusion-related morbidity and mortality. Both basic and clinical researches have demonstrated that immune priming is a fundamental step for lung injury. Antigen-antibody reactions trigger a series of events that lead to TRALI, which mainly relate to HLA and HNA antibodies of blood products. The prevetion is very important for TRALI and research on mechanism of TRALI will be still a key point.

Hypertension is one of the most common cardiovascular diseases. In recent years, a large number of studies have shown that oxidative stress is the main reason for the vascular injury, which may be an important pathological mechanism that can lead to hypertension. The increasing level of reactive oxygen species (ROS), leading to increased oxidative stress induced an increase in blood pressure. Hypertension will further promote the generation of ROS, leading to tissue oxidative injury. Recently, the anti-oxidative stress therapy research attracted the attention of many researchers at home and abroad. The clinical application of oxidative stress in the treatment of hypertension have achieved certain results. The aim of the present review is to describe the contribution of oxidative stress to hypertension and anti-oxidative stress pharmacotherapy.

Thyroid hormones play a wide range of important physiological activities in almost all organism. As changes in these hormones levels, observed in hypothyroidism and hyperthyroidism, promote serious derangements of the cardiovascular system, it is important to know their mechanisms of actions. Although the classic genomic actions which are dependent on interaction with nuclear receptors to modulate cardiac myocyte genes expression, there is growing evidence about T₃ and T₄-triggered nongenomic pathways, resulting from their binding to plasma membrane, cytoplasm, or mitochondrial receptors that leads to a rapid regulation of cardiovascular functions. Disappointedly, little attention is paid to the rapid nongenomic actions of thyroid hormones on cardiovascular system. This paper reviews the effects of thyroid hormones on cardiovascular function via nongenomic actions involving extranuclear receptors, second messengers, or effect proteins. A full understanding of the link between thyroid hormones and cardiovascular functions should be beneficial for appropriate management of cardiovascular diseases by modulating thyroid hormones levels.
