Objective To improve the effects of health education(HE)and satisfaction degree on HE of inpatients by executing hierarchical full-responsibility nursing. Methods Fourteen wards were randomly chosen form the hospital and divided into the control group and the experimental group, each group having 7 wards. The control group carried out routine holistic nursing model, and the experimental group carried out a new hierarchical full-responsibility nursing system. Reforming nursing scheduling and diminishing the nursing unit to assure that the patients acquired the continous and stable nursing service when they were in hospital. The effect and the degree of satisfaction of HE were compared between two groups after 6 months. Results The effects of HE in the experimental group were significantly better than those in the control group, and the degree of satisfaction on HE in the experimental group was much higher than in the control group. Conclusions The hierarchical full-responsibility nursing system can give patients systematic and normalized HE. It can significantly improve the effects and the degree of satisfaction on HE.

Objective To develop a dual real-time fluorescent RT-PCR method for rapid detection of enterovirus(EV)and en terovirus type 71(EV71).Methods Specific primers and probes were designed and the dual real-time fluorescent RT-PCR reaction system was established.The quantitative standard curve was drawn;its sensitivity and precision were evaluated.Feces and throat swab specimens of 109 clinical patients with hand foot and mouth disease were collected and tested by using this method.Then the obtained results were compared with those detected by commercial EV71 PCR kit.Results The relative coefficient(2)of EV and EV71 standard curve established by the dual real-time fluorescent RT-PCR method were both 0.998.Its sensitivity reached 0.5 TCID50/mL for detecting EV and 0.05 TCID50/mL for detecting EV71.The within-run precision for detecting EV and EV71 was ＜3％ and total precision≤4％.The results showed good specificity for the detection of enterovirus and non-enterovirus.In 109 detected clinical samples,84 cases of EV positive samples were detected,in which 56 cases were EV71 positive with the total positive rate of 51.4 ％,which was consistent with the result of simple fluorescent RT-PCR commercialization kit(P=1.000).Conclusion The established dual real-time fluorescent RT-PCR method has high sensitivity and good stability,which has an important significance for early high throughput rapid diagnosis of hand foot and mouth disease.

OBJECTIVETo observe mainfestations of syndrome and biochemical indices of hypertensive model rats with excessive accumulation of phlegm-dampness syndrome (EAPDS), and to explore its possible pathological mechanism.

METHODSEAPDS rat model was prepared in 50 Wistar rats by feeding with high fat forage. Meanwhile, a normal control group consisting of 10 Wistar rats was set up by feeding with normal forage. After 25-week continuous feeding, 22 rats with body weight (BW) and blood pressure (BP) exceeding 25% those of the control group were selected as a model group. BW, BP, blood lipids, and related serological indicators were detected in all rats. Morphological changes of target organs were observed. mRNA expression levels of leptin receptor (LepR), Janus kinase2 (Jak2), signal transducer and activator of transcription 3 (Stat3), suppressor of cytokine signaling-3 (Socs3), angiotensin II receptor type 1 (AT1), angiotensin II receptor type 2 (AT2), phosphatidylinositol 3 kinase (P13K), serine threonine kinase (Akt), nuclear factor of kappa B (NF-κBp65), inhibitor of nuclear factor kappa-B kinase α (IKKα), NF-kappa-B inhibitor β (lKKβ), NF-kappa-B inhibitor α (IKBα), and AMP-activated protein kinase (AMPK) were detected by quantitative real-time PCR (qPCR). Expression levels of AT1 and LepR in aorta were detected by immunohistochemical assay and Western blot respectively.

RESULTSCompared with the control group, BW, BP, and blood lipids increased; serum levels of leptin (Lep) , Ang II, Hcy, ET-1, TNF-α, IL-6, and p2-MG increased, but NO decreased in the model group (P < 0.05, P < 0.01). Aortal endothelial injury and smooth muscle cell proliferation occurred in the model group, accompanied with heart and renal injury. Compared with the control group, mRNA expression levels of LepR, Jak2, Stat3, Socs3, AT1 , PI3K, Akt, NF-κB p65, IKKβ, IKBα, and AMPK in aorta were up-regulated significantly (P < 0.05), while the expression of IKKa decreased (P < 0.05). Immunohistochem- ical staining showed, brownish yellow deposit of AT1 and LepR was obviously increased, with more extensively positive distribution. Western blot results showed, as compared with the control group, protein expression levels of AT1 and LepR obviously increased in the model group (P < 0.05).

CONCLUSIONSModel rats exhibited typical syndromes of EAPDS. They put up weight with fat abdomen, gloomy hair, poor appetite, hypersomnia, lowered activities , reduced food intake, loose stool, dark red tongue, white tongue with white, thick, greasy fur. Lep could be taken as one of objective indicators for evaluating hypertension rat model with EAPDS.

[Objective] To observe the effect of cyclosporine A (CSA) on the activity and expression of MMP-2 and MMP-9 in renal tubular epithelial cells. [Methods] NRK52E cells were cultured until its reached confluent. Then NRK52E cells were exposed to different concentration of CSA (0, 0.42, 0.84, 4.2, and 8.4 μmoL/L) for 48 h or 72 h respectively. MMP-2 and MMP-9 activities were detected by gelatin zymography. The expression of MMP-2 and MMP-9 mRNA were detected by RT-PCR. [Results] MMP-2 activity and mRNA levels were decreased in a dose dependent manner after exposed to different concentration of CSA for 48 h or 72 h in NRK52E cells. Compared with control (CSA 0 μmoL/L), CSA 0.42, 0.84, 4.2, 8.4 μmoL/L decreased the MMP-2 activities to 27%, 24%, 11%, and 9% respectively; The differences are significant, P<0.05. But the MMP-9 activity and mRNA levels were increased after exposed to CSA for 48 h or 72 h in NRK52E cells. Compared with control group, CSA 4.2 μmoL/L exposure increased MMP-9 activity to 438% in 48 h, and 237% in 72 h; the differences are significant as well, P<0.05. [Conclusion] A dose-dependent decrease in the expression and activity of MMP-2, and the up-regulation of the expression and activity of MMP-9 by CSA in renal epithelial cells may related to CSA associated tubulointerstitial damage.

The anti-hepatitis B virus (HBV) effects and its mechanisms of the ethanol extracts of Hypericum perforatum L. (EHP) in vitro were explored. HepG2 2.2.15 cells, a stable HBV-producing cell line, were cultured as the model system to observe the anti-HBV effect. The viral antigens of cellular secretion, HBsAg and HBeAg, were determined by enzyme linked immunosorbent assay (ELISA). The quantity of HBV-DNA released in the supernatant was assayed by real-time PCR. In order to understand the mechanisms of the suppression of HBV replication, all HBV promoters (Cp, Xp, S1p, S2p and Fp) with luciferase reporter gene were transfected into HepG2 cells respectively. Then the activities of viral promoters were examined by luciferase reporter assay. It was found EHP effectively suppressed the secretion of HBsAg and HBeAg from HepG2 2.2.15 cells in a dose-dependent manner, as well as the extracellular HBV DNA. And EHP could selectively inhibit the activity of HBV promoter Fp. Our data suggest that EHP exerts anti-HBV effects via inhibition of HBV transcription, which helps to elucidate the mechanism underlying the potential therapeutic value of EHP.
