To discuss the availability of evaluation on the dissolution studies of the multicomponents in traditional Chinese medicine, the in vitro dissolution of total composition of the tablet of rhizomes of Ligusticum chuanxiong components and its correlation with the in vivo were studied by the method of area under the absorbance-wavelength curve (AUAWC). Taken the tablet of rhizomes of Ligusticum chuanxiong components which is composed of sodium ferulate and ligustrazine hydrochloride as subject model, the dissolution tests were carried out with basket method. The plasma concentrations of tablets in different rats were determined by AUAWC at different interval times. The in vivo absorption percentage was calculated by Wagner-Nelson equation to evaluate the in vitro and in vivo correlation. According to the results, the cumulative dissolution in vitro of total composition of tablets of rhizomes of Ligusticum chuanxiong components at 60 min was 90.65% in water by AUAWC. The in vivo pharmacokinetics is fitted with an one-compartment model. The linear equation based on the cumulative dissolution rate (fr) and absorption percentage (fa) at 5, 10, 20, 30 and 60 min was fa = 0.819 7 fr+0.183 and the correlation coefficient was 0.959 5, which showed a good correlation between the in vitro dissolution and the in vivo absorption percentage. The method of AUAWC can be used accurately, feasibly and conveniently to evaluate the in vitro and in vivo correlation of total composition of tablets of rhizomes of Ligusticum chuanxiong components, which will provide better guidance to study the in vitro and in vivo correlation of sustained release preparation etc under complex system of traditional Chinese medicine in the future.

Objective To establish the murine animal model for acute graft-versus-host disease after allogeneic hematopoietic stem cell transplantation (HSCT). Methods T cell-depleted (TCD) BM cells from allogeneic C57BL/6 mice were harvested and prepared from the marrow of the femurs and tibias. Age of 4 to 6 weeks’ BALB/c mice received 900 cGy total body irradiation ( TBI) from a 137Cs source. Two to four hours later,the mice were injected intravenously ( i. v. ) 5 × 106 TCD-BM cells with 1. 25 × 106 or 2. 5 × 106 or 5 × 106 splenic cells from allogeneic C57BL/6 mice,and respectively divided them into experimental group 1,experimental group 2 and experimental group 3. TCD-BM only was used as the negative control group of GVHD. Ten mice were used for each group. The establishment of aGVHD model was evaluated with a clinical GVHD scoring system,survival rate and target-organ damage. Results On 7 to 14 days after transplanta-tion,the typical clinical GVHD manifestation of severe diarrhea,hogback,activity reduced and ruffling were observed in experimental group 2. Furthermore,the aGVHD target organs of colon,lung and liver were harvested and made histological paraffin sections,then the obviously path-ological tissue damages of GVHD were detected under microscope. And the survival rate was lowed down to 0 on 45 days after transplantation in experimental group 2. On the contrary,no obviously clinical manifestation of aGVHD were observed in the control group,experimental group 1 and group 3. On 60 days later, the survival rate was 80% in experimental group 1 and 100% in control group. However,no mice was sur-vived on 10 days later in group 3. Conclusion BALB/c mice aGVHD model after allogeneic HSCT is successfully established by injecting i. v. 5 × 106 TCD-BM cells with 2. 5 × 106 splenic cells from allogeneic C57BL/6 mice.

Medicinal values and their chemical bases of Paris (Trilliaceae) are reviewed. Paris plants include 40 species and varieties. Among them, 18 ones are medicinal plants with similarity in traditional uses. Fourteen species have been studied phytochemically, which led to isolation of 207 compounds including 121 steroidal saponins. These saponins are major active constituents from Paris plants, which can explain the traditional uses of the plants to treat cancer, malignant boil, bleeding, gastritis, and so on. The similarity in medicinal uses and chemical constituents of Paris plants implies the possibility of resource substitution among these species. It is worth to further investigate Paris plants in chemical constituents, pharmacological activity, biological property, and toxicology.

OBJECTIVETo explore the regulative effects and possible mechanisms of emodin on autophagy induced by starvation in rat's renal tubular epithelial cells (NRK-52E).
METHODFirstly, Hank's balanced salt solution (HBSS) was used to induce starvation and the protein expression of microtubule-associated protein 1 light chain 3 (LC3) I/II, an autophagic marker of mammalian congener, was detected by Western blot with or without the treatment of emodin. Secondly, the changes of red fluorescent protein-microtubule associated protein light chain3 (RFP-LC3) fluorescent particles, treated by HBSS (1 mL) and bafilomycin A1 (10 nmol x L(-1)) with or without emodin, were observed through fluorescence microscopy in NRK-52E cells transient transfected by RFP-LC3 plasmid. With the intervention of mammalian target of rapamycin mTOR inhibitor rapamycin (100 nmol x L(-1)) , the effect of blocking mTOR signaling pathway on autophagic inhibition of emodin was observed. Finally, the effect of mTOR signaling pathway on autophagic inhibition of emodin was further evaluated through the over-expression of endogenous mTOR inhibitory protein DEP domain-containing mTOR-interacting protein-(DEPTOR).
RESULTHBSS hunger could induce high protein expression of LC3 II in NRK-52E cells, and the intervention of emodin could reverse the unregulated protein expression of LC3 II induced by HBSS. The number of RFP-LC3 fluorescent particles was increased after the co-treatment of HBSS and bafilomycin A1, and this increase was inhibited by emodin. After the co-treatment of rapamycin, emodin and HBSS, the LC3 II protein expression restored in NRK-52E cells, compared with the treatment of HBSS. Over-expression of DEPTOR could also block the inhibitive effect of emodin on LC3 II protein expression.
CONCLUSIONEmodin could inhibit HBSS-induced LC3 II protein expression and the activation of autophagy in NRK-52E cells, and the effect of blocking autophagy may be mediated through mTOR signaling pathway.

OBJECTIVETo study on the reliability of the Akagi line as a reference axis to guide for rotational alignment of the proximal tibial component in total knee arthroplasty (TKA) the rotational alignment reference bony landmarks of the proximal tibial component on magnetic resonance image (MRI) were measured.
METHODSFrom January 2010 to December 2013, 80 normal knees of Chinese volunteers including 35 males and 45 females with an average age of (35.4±6.1) years were reviewed. The images of the knees were obtained by MRI. The surgical epicondylar axis (STEA) was identified in the femoral transverse sections and then was projected to the side of tibia, forming the SETA'. A line connecting the medial border of the patellar tendon and the middle of the posterior cruciate ligament insertion (Akagi line) and its vertical line (AK), as well as a line connecting the medial 1/3 of the patellar tendon and the middle of the posterior cruciate ligament insertion and its vertical line (AP), were identified in the tibial transverse sections. The angles were measured between the AK, AP and STEA'.
RESULTSThe angle between AK and STEA' was (0.59±2.07)°, and there was no significant difference between the two lines (t=-2.54, P=0.13). The mean angle between AP and STEA' was (3.21±2.04)°, and there was a significant difference between the two lines (t=14.05, P<0.05). There was a significant difference between the AK and AP (t=-11.68, P<0.05).
CONCLUSIONThe reliability of the Akagi line as a reference axis to guide for rotational alignment of the proximal tibial component in TKA is good.

In chronic kidney disease (CKD), inflammatory responses during the progression of renal tissue and tissue injury related causes its progression to end-state renal disease. Among them, nuclear factor (nuclear factor, NF)-kappaB signaling pathway by regulating the corresponding nuclear expression of target gene transcription, as well as affecting the synthesis of inflammatory mediators, induction of inflammation lead to kidney damage and renal fibrosis. Some single herbs and their extracts (such as Astragali Radix, Scutellariae Radix, Ginkgo Folium) and some traditional Chinese medicine (such as Danggui Buxue decoction, Qilian decoction) can reduce the inflammatory damage induced by renal tissue NF-kappaB signaling pathway and delay the progression of CKD.

OBJECTIVETo explore the effects and molecular mechanisms of rhein on reducing starvation-induced autophagic protein expression in renal tubular epithelial ( NRK-52E) cells.
METHODHank's balanced salt solution (HBSS) was used to induce NRK-52E cells to be in the state of starvation. After the intervention of HBSS for 0, 0.5,1, 2 and 6 hours, firstly, the protein expression of microtubule-associated protein 1 light chain 3(LC3 I/II), which is a key protein in autophagy, was detected. Secondly, the protein expressions of mammalian target of rapamycin (mTOR) and phosphorylated-mTOR Ser2448 (p-mTOR S2448) were examined. And then, after the co-treatment of rhein (5 mg x L(-1)) and HBSS (1 mL) without or with mTOR inhibitor, rapamycin (100 nmol x L(-1)), the protein expressions of LC3 I/II, mTOR and p-mTOR S2448 were tested, respectively.
RESULTHBSS could induce the up-regulation of LC3 II and the down-regulation of p-mTOR S2448 at protein expression level in NRK-52E cells. The co-treatment of rhein and HBSS could reversely regulate the protein expressions of LC3 II and p-mTOR S2448 in NRK-52E cells significantly. The co-treatment of rapamycin, rhein and HBSS could recover the level of LC3 II protein expression in HBSS-intervened NRK-52E cells.
CONCLUSIONHBSS induces autophagy in renal tubular epithelial cells by inhibiting mTOR signaling pathway activation. Rhein reduces the autophagic protein expression in renal tubular epithelial cells through regulating mTOR signaling pathway activation, which is the possible effects and molecular mechanisms.

OBJECTIVETo demonstrate the effects and mechanisms of Qifu decoction( QFD) on renal interstitial fibrosis (RIF) in model rats with yang-deficiency syndrome.
METHODThe rats were randomly divided into 3 groups, the Sham group (Group A), the Model group (Group B), the Qifu decoction group (Group C) and the Enalapril group (Group D). The RIF model was established by adenine administrated and unilateral ureteral obstruction (UUO) of the left ureter. After the model was successfully established, the rats in Group C and D were administrated with QFD or the Enalapril suspension,while the rats in Group A and B were administrated with distilled water. All rats were administrated for 3 weeks. Before administration and at the end of week 1, 2 and 3, the rats were weighted, and 24 h urinary protein excretion (Upro), urinary β2-microglobulin (Uβ2-MG) and urinary N-acetyl-D-glucosaminidase (NAG) were examined, respectively. All rats were killed after administration for 3 weeks. Blood and renal tissues were collected, renal morphology and tubulointerstitial morphology were evaluated, respectively. Serum cyclic adenosine monophosphate (cAMP), cyclic guanosine monophosphate (cGMP), blood urea nitrogen (BUN), serum creatinine (Scr) and uric acid (UA) were detected, respectively. The protein expressions of E-cadherin, α-smooth muscle actin(α-SMA), transforming growth factor-β1 (TGF-β1), onnective tissue growth factor (CTGF) extracellular signal-regulated protein kinase 1/2(ERK1/2) and phosphorylated-ERK1/2 (p-ERK1/2) in kidney were evaluated, respectively.
RESULTQFD ameliorated serum cAMP level and the rate of cAMP/cGMP, attenuated urinary β2-MG level, NAG level and renal tubulointerstitial fibrosis, increased E-cadherin protein expression, and reduced α-SMA, TGF-β1, CTGF and p-ERK1/2 protein expressions in the kidney. However, QFD had no influence on renal function in vivo. In addition, these effects were better than those of the model rats treated by Enalapril.
CONCLUSIONQFD could alleviate yang-deficiency parameters, as well as urinary β2-MG level and NAG level in model rats induced by adenine administration and UUO. Moreover, QFD could improve EMT and RIF by up-regulating E-cadherin protein expression, and down-regulating α-SMA, TGF-β1, CTGF and p-ERK1/2 protein expressions, the key molecular in ERK1/2 signaling pathway.
