OBJECTIVETo observe the effect of CKJ Recipe (consisting of Cordyceps sinensis polysaccharide, amygdaloside, and gypenosides) containing serum on the activation of rat primary hepatic stellate cells (rHSCs) and to explore its pharmacological mechanism.

METHODSrHSCs were isolated form liver and cultured for four days. Then they were divided into the normal control group, the model group, and the CKJ group. rHSCs in the model group and the CKJ group were treated with 2.5 ng/mL transforming growth factor beta1 (TGF-beta1) in serum-free DMEM for 24 h. Serum free DMEM (containing no TGF-beta1) was taken as the control for the normal control group. rHSCs in the CKJ group were treated with 5% CKJ-containing serum for 24 h. rHSCs in the other two groups were treated with 5% blank serum for 24 h.The protein expression level of a smooth muscle actin (alpha-SMA) was determined using high throughput screening (HCS) and Western blot. mRNA expression levels of alpha-SMA, collagen I (Col-I), platelet-derived growth factor receptor beta (PDGF-betaR), TGF-beta1, transforming growth factor beta receptor 1 (TGF-betaR1), and transforming growth factor beta receptor 2 (TGF-beta R2) were detected using quantitative RT-PCR.

RESULTSCompared with the normal control group, the protein expression level of alpha-SMA, mRNA expression levels of alpha-SMA, Col-I, PDGF-betaR, TGF-beta1, TGF-betaR1, and TGF-betaR2 significantly increased in the model group (P<0.05, P<0.01). Compared with the model group, the protein expression level of alpha-SMA, mRNA expression levels of alpha-SMA, Col-I, PDGF-betaR, TGF-beta1, TGF-beta1, and TGF-beta R2 significantly decreased in the CKJ group (P<0.05, P<0.01).

CONCLUSIONCKJ containing serum could inhibit the protein expression level of o-SMA, which was probably related with inhibiting TGF-beta1 and its related receptors.

OBJECTIVETo compare the therapeutic effects between the Hwato neuro and muscle stimulator (SXDZ-100) and the regular electronic stimulator (SDZ-II) on chronic functional constipation.

METHODSSixty-four cases of chronic functional constipation were randomly divided into a (SXDZ-100) observation group (n = 33) and SDZ-II control group (n = 31). For the SXDZ-100 group, under the considerations of patients' endurance, Zhigou(TE 6) and Tianshu (ST 25), Zusanli (ST 36) and Shangjuxu (ST 37) were punctured and then the courle of acupoints on the same side were connected with SXDZ-100 apparatus in reinforcing and reducing by twirling and rotating manipulation wave for 30 min, while in the control group SDZ-II apparatus was applied in the same way mentioned above with disperse-dense wave at frequency of 1Hz/20Hz for 30 min. By means of clinical therapeutic effect evaluation and clinical symptom score, the contrast between two groups can be made.

RESULTSAlthough the total effective rates were both 100.0%, the rate of short term effects in SXDZ-100 group (54.6%, 18/33) is significantly higher than that in SDZ-II group (29.0%, 9/31) (P < 0.05). After the treatment, the clinical symptom scores in both groups decreased significantly (both P < 0.05). And the therapeutic effective indices of the SXDZ-100 group were significantly higher than those of the SDZ- II group (P < 0.05).

CONCLUSIONThe therapeutic effect of Hwato neuro and muscle stimulator (SXDZ-100) on chronic functional constipation is superior to that of a regular electronic stimulator (SDZ-II).

OBJECTIVETo explore method of recombinant gene lentivirus containing LIM mineralization protein-1 (LMP-1) in transfecting bone marrow mesenchymal stem cells (BMSC), and to observe the effect of gene LMP-1 on proliferation effect and expression of BMSC.

METHODSSix clean SD rats aged 4 weeks were selected, bone marrow mesenchymal stem cells were extracted under sterile conditions and cultured to the third generation, then divided into three groups:control group (the third generation of BMSC), lentiviral vector transfection group (PGC-FU-GFP and Polybrene were injected into the third generation of BMSC) and recombinant gene transfection group (PGC-FU-LMP-1-GFP and Polybrene transfection were injected into the third generation of BMSC). After 48 hours' transfection, fluorescent expression were detected under immuno-fluorescence microscopy; lentiviral transfection efficiency were detected by flow cytometry; effect of lentiviral transfection on BMSC were evaluated by MTT; gene expression of transfected cells were determined by Western Blot.

RESULTS1) The third generation of BMSC was cultured successfully,and transfected with MOI:100. After 48 hours, green fluorescent expression were detected and transfection efficiency was 67% under immuno-fluorescence microscopy; 2) Compared to control group, there were no statistical differences between control group and other two groups; 3) Western blot teast showed that 72KDa specific band was observed in recombinant gene transfection group and its size was similar to LMP-1 fusion protein (50 kDa+28 kDa=78 kDa).

CONCLUSIONThere is no effect of recombinant gene lentivirus containing LIM on BMSC, and can effectively influence the expression of LMP-1.

0.05).However,the shorter the history of the disease,the better the efficacy of the treatment.The younger the patient was,the better the efficacy of the treatment.Conclusions Vulva dystrophy can be treated with focused ultrasound effectively and safely.This approach appears to be a new promising treatment method.

ObjectiveTo investigate the quality of life (QOL) of the epilepsy patients and the factors affected the QOL.Methods200 cases were investigated using the Quality of Life in Epilepsy Inventory 10 (QOLEI-10) and the Washington Psychosocial Seizure Investigate (WPSI). 200 healthy persons were chosen as normal control group. ResultsThe QOL of the patient group were significantly poor as compared with that of normal control group(P<0.01). The factors that the patients always faced with were disability in the attack control, short in money, unemployment, restriction of movement, disability in intercommunication, psychological disorder (depress, strain, anxiety, dread, shame feel, cognitional dysfunction, etc.), as well as the difficult to get professional curtains, taking medicine improperly and side effects of the medicine. Conclusions The factors mentioned, which were usually neglected by many doctors, do affect the QOL of epilepsy patients, and hinder the epilepsy treatment effectively.

Wistar rats with different levels of iodine nutrition were killed after 3,6 and 12 months of experiments.Serum thyroid hormones were assayed with RIA.The activity of typeⅠdeiodinase(DⅠ)and typeⅡdeiodinase(DⅡ)was measured based on the release of radioiodide from the ~(125)Ⅰ-labeled substrate.The result showed that hypothyroidism reflected by decreased T_4 happened during the initial phase of iodine deficiency.The activity of DⅠand DⅡin rats was raised significantly in iodine deficiency groups.An excess of iodine inhibited DⅠactivity resulting in decreased serum TT_3 and FT_3.However,DⅡactivity increased in rats with iodine excess, attributing to the inactivation of T_3 and T_4 to the substrate of DⅡenzyme.

OBJECTIVETo explore the effects of soothing liver and invigorating spleen recipes on lipopolysaccharide(LPS) induced hepatocyte inflammation of rats and TLR4/p38MAPK signal pathway.

METHODThe hepatocytes of SD rats were cultured and identified in vitro. The medicated serum of soothing liver and invigorating spleen recipes was prepared. The hepatocytes were treated with soothing liver and invigorating spleen recipes. Then Interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) expression in cultural supernatants were assayed by ELISA. The expressions of Toll-Like 4 (TLR4), p38 mitogen activated protein kinases (p38MAPK) and p-p38 mitogen-activated protein kinase (p-p38MAPK) were detected by Western blot.

RESULTThe rat medicated serum of soothing liver and invigorating spleen recipes was extracted for 2-3 mL. The purified rat hepatocytes were 1.5 x 10(8)-2.0 x 10(8). The cell viability was above 95% detected by Typan blue staining. The hepatocytes were identified by immumofluorescence assay. The detection of hepatocyte cultural supernatants: compared with that of the control group, IL-6 and TNF-α expression were increased in the LPS group (P < 0.01). While compared with that of the LPS group, the expressions of IL-6 and TNF-α were decreased after soothing liver and invigorating spleen recipes intervention (P < 0.01). The detection of hepatocyte proteins: compared with that of the control group, the protein expressions of p38MAPK, p-p38MAPK and TLR4 were all increased significantly in the LPS group (P < 0.01). Compared with that of the LPS group, the protein expressions of p38MAPK was decreased significantly in SB239063 group and it was also decreased in the soothing liver and invigorating spleen recipes group, but with no significant difference. Compared with that of the LPS group, p38MAPK expression was reduced significantly in the soothing liver and invigorating spleen recipes group and the SB239063 (p38MAPK pathway inhibitor) group (P < 0.01). TLR4 protein expression was decreased markedly in the soothing liver and invigorating spleen recipes group (P < 0.01) but had no difference between the SB239063 group and the LPS group.

CONCLUSIONThe soothing liver and invigorating spleen recipes may regulate hepatocyte inflammatory injury of rats through TLR4/p38MAPK signaling pathway.

Pseudoallergic reactions of Qingkailing injection (QKLI) was assessed by vascular hyperpermeability which were indicated by ear blue staining in ICR mice after single intravenous injection of QKLI mixed with Evans blue (EB) and skin blue spot formation in SD rats after intradermal injection of QKLI and intravenous injection of EB. In addition, QKLI-induced histamine, VEGF, TNF-alpha release was measured after ICR mice received the single dosing of QKLI iv. The mild vascular hyperpermeability characterized by ear blue staining could be observed in mice after intravenous injection of QKLI and EB. Intracutaneous injection of 50 micro L of test solution containing QKLI (25,50 microL) in rat back skin caused obvious local vascular hyperpermeability at the injection sites so as to result the larger diameters of blue spots than that in negative control group (P <0. 01). QKLI induced a significant increase of VEGF and a slight elevation of histamine in mice after intravenous administration, while TNF-alpha showed no change after QKLI iv. The results in this study indicated that both intravenous injection and intracutanous injection of QKLI could induce vascular hyperpemeability so as to cause pseudoallergic reaction in mice and rats. QKLI-induced pseudoallergic reaction may be associated with the release of histamine and VEGF.
