At present, TCM treatment of diarrhea-predominant irritable bowel syndrome (IBS-D) is based on the combination of disease differentiation and syndrome differentiation. Therefore, the establishment of IBS-D of liver stagnation and spleen deficiency syndrome combined with animal model as a combination of traditional Chinese and Western medicine innovation theory has become increasingly concerned about, and gradually become a new direction for the development of TCM experimental animal model. This article reviewed the research progress in IBS-D liver and spleen deficiency syndrome in recent years, discussed the establishment of IBS-D liver stagnation and spleen deficiency animal model and research ideas for the treatment of IBS-D, and provided references for mechanism research of TCM treatment for IBS-D and research and development of new medicine.

Fifty-six patients with Graves' ophthalmopathy(GO)were treated with antithyroid drug and oral prednisone for three months,TSH receptor antibody(TRAb)level was reduced,GO activity and severity of some patients were ameliorated but still positively associated with TRAb.It suggests that TRAb not only triggers off GO but also plays a possible role in the maintenance of the autoimmune process in GO.

BACKGROUNDHepatocellular carcinoma (HCC) ranked the second among the causes of cancer mortality in China since the 1990s. Up to now, medication still plays an important role in the treatment of HCC. The therapies based on the allicin as a potential chemopreventive analog although is in its infancy at the present time, may have a significant role in the future management of HCC. Diallyl trisulfide (DATS) is a natural compound derived from garlic. In this study, we investigated the inhibitory effects of hepatic targeted polybutylcyanoacrylate nanoparticles of diallyl trisulfide (DATS-PBCA-NP) on orthotopic transplanted HepG2 hepatocellular carcinoma in nude mice.

METHODSDATS-PBCA-NP were detected by transmission electron microscope (TEM) and high-performance liquid chromatography (HPLC). The orthotopic transplantation HCC models were established by implanting HCC HepG2 xenograft bits under the envelope of the mice liver. Successful models (n = 29) were divided into 4 groups: normal saline (NS), empty nanoparticles (EN), DATS and DATS-PBCA-NP were intravenously administered to the mice respectively for 2 weeks. In vivo antitumor efficacy was evaluated by the measurement of tumor volume. Terminal deoxynucleotidyl transferase mediated dUTP nick end labeling (TUNEL) assay and protein levels of apoptosis and cell proliferation proteins by immunoblotting in tumor tissues were performed to elucidate the possible mechanism.

RESULTSDATS-PBCA-NP possessed smooth and round appearance, dispersed well, and released in vitro in accord with double phase kinetics model. DATS-PBCA-NP changed the tissue/organ distribution of DATS in vivo. The successful rate of tumor implantation was 100%. Intravenous administration of DATS-PBCA-NP significantly retarded the growth of orthotopically transplanted hepatoma in BALB/c nude mice (compared with the other three groups, all P < 0.05) without causing weight loss (P > 0.05). TUNEL staining showed that the tumors from DATS-PBCA-NP treated mice exhibited a markedly higher apoptotic index compared with control tumors. Western blot analysis of tumor tissue revealed that the down-regulated expression of proliferation cell nuclear antigen (PCNA) and Bcl-2 proteins in DATS-PBCA-NP group, and there were no significant differences in the expression of Fas, FasL and Bax proteins among the four groups (P > 0.05).

CONCLUSIONSDATS-PBCA-NP has good prolonged release effect in vivo and hepatic-targeted activity, and significant anti-tumor effect on the orthotopic transplantation HCC model in mice in association with the suppression of proliferation and the induction of apoptosis of tumor cells. These advantages are probably due to their liver targeting characteristics and consequently bring a higher anti-tumor activity.

OBJECTIVETo observe the effects of Huganjiexian decoction on rat hepatic fibrosis and the creation of cytokines.

METHODSRat hepatic fibrosis was induced by intraperitoneally injection of carbon tetrachloride. At the same time, these rats were treated with different dosages of Huganjiexian decoction. Sho-saiko-to compound treating group and Fufangbiejiarangan Tablets treating group were used as positive controls. After twelve weeks, all rats were executed. Histopathologic changes were observed after H.E and Masson stainings. The expression of collagen type I, collagen type III, TGF-beta 1 and PDGF-BB in liver were detected by immunohistochemical staining.

RESULTSCompared with fibrotic group, hepatic fibrosis in decoction groups was significantly improved. In decoction groups, levels of collagen type I, collagen type III, TGFbeta1 and PDGF-BB were decreased, especially in the low-dose curcumin group. The TGF-beta 1 positive percentage were 7.56%+/-2.18%, 29.25%+/-7.84%, 13.54%+/-4.15%, 21.82%+/-6.64%, 20.06%+/-7.14%, 13.78%+/-4.35%, 12.75%+/-3.98% in liver tissues from normal group, model group, low, middle, high curcumin, Sho-saiko-to compound and Fufangbiejiarangan Tablets treating groups respectively (P less than 0.05); while the PDGF-BB positive percentage were 1.68%+/-0.41%, 11.70%+/-2.28%, 3.65%+/-0.76%, 5.24%+/-1.04%, 6.37%+/-1.12%, 4.16%+/-0.61%, 3.38%+/-0.56% in liver tissues from those groups respectively (P less than 0.05).

CONCLUSIONHuganjiexian decoction can improve rat hepatic fibrosis, possibly via inhibiting the expression of collagen type I, collagen type III, TGFbeta1 and PDGF-BB.

OBJECTIVETo observe the effect of Shenfu injection (SFI) in treating non small cell lung cancer (NSCLC) patients on quality of life with gemcitabine (GEM) plus cisplatin (GP) regimen.

METHODSThirty-four patients were ready to receive GP regimen chemotherapy for treating NSCLC disease, according to lot-drawing, they were divided into SFI pre-treatment group (18 cases) and SFI post-treatment group (16 cases). SFI pre-treatment group: During the first treatment course, chemotherapy was begun with SFI 60 ml, intravenous dripping on the 3rd day, once daily, consecutively for 10 days; on the 1st day, GP regimen (GEM 1250 mg/m(2), intravenous dripping, on the 1st and 8th day; cisplatin 70 mg/m(2) on the 2nd day; 21 days as one cycle) was carried out; in the second treatment course GP regimen was merely given to serve as the self-control. SFI post-treatment group: the medicament sequence order was reversed from that of pre-treatment group. Using dual international quality of life (QOL) scores, the effect of SFI on the patients' QOL was observed through randomized self pre- and post-crossover control.

RESULTSThe QOL in the 34 patients after being treated by SFI in combination with GP chemotherapy regimen in one group, and GP chemotherapy regimen alone in the other, was improved in different degrees, with significant difference (P < 0.01); comparison of SFI combined with GP chemotherapy regimen with GP chemotherapy alone showed that QOL in patients was significantly different (P < 0.01).

CONCLUSIONSFI could improve QOL in patients with NSCLC who were treated with GP regimen.

OBJECTIVETo study the clinical significance of tidal breathing lung function test in 1-4 years old children with wheezing diseases.

METHODSA total of 141 1-4 years old children with wheezing diseases were enrolled as the observed groups (41 cases of asthma, 54 cases of asthmatic bronchitis, and 46 cases of bronchopneumonia). Thirty children without respiratory diseases were enrolled as the control group. All the recruits underwent tidal breathing lung function test. The observed groups underwent bronchial dilation test, and tidal breathing flow volume (TBFV) parameters were evaluated before and after bronchial dilation test.

RESULTSThe observed groups showed obstructive ventilatory disorder (65%) according to the TBFV loop, and their ratio of time to peak tidal expiratory flow (TPTEF) to total expiratory time (TE) and ratio of volume to peak expiratory flow (VPEF) to total expiratory volume (VE) were significantly lower than in the control group (P<0.05). The asthma subgroup had significantly improved TPTEF/TE and VPEF/VE after bronchial dilation test (P<0.05). Taking an improvement rate of ≥ 15% either for TPTEF/TE or for VPEF/VE as an indicator of positive bronchial dilation test, the bronchial dilation test had a sensitivity of 47% and a specificity of 84% in diagnosing asthma in 1-4 years old children. The positive rate was 28% among the children in the asthma subgroup with an TPTEF/TE ratio of ≥ 23% before bronchial dilation test, versus 65% in those with an TPTEF/TE ratio of <23%.

CONCLUSIONSObstructive ventilatory disorder is the main impairment of tidal breathing lung function in 1-4 years old children with wheezing diseases. Tidal breathing bronchial dilation test can reflect a reversal of airway obstruction to a certain extent. The sensitivity of bronchial dilation test for the diagnosis of asthma is not satisfactory in 1-4 years old children with wheezing diseases, but this test has a relatively high diagnostic value in children with severe airway obstruction.

OBJECTIVETo explore the characteristics of the whole genome of the influenza H1N1 virus of the mild and severe cases in Beijing.

METHODSA total of 21 samples of throat swabs were collected from surveillance-designated hospitals between June and December in 2009, including 10 severe cases (4 death cases) and 11 mild cases. RNA of the virus were extracted,and the amplified primers of the whole genome were designed.Reverse transcription and PCR were performed to the RNA and then the PCR product was sequenced by software to analyze the evolution of the viral genes and the variation of the amino acids.

RESULTSCompared with the reference vaccine strain A/California/07/2009 (H1N1), the genetic nucleotide homology in the eight segments of the pandemic H1N1 virus in Beijing in 2009 was higher than 99%, without significant variation. Among them,the genetic distance of hemagglutinin (HA), neuraminidase (NA) and nucleoprotein (NP) was comparatively far, separately 0.0050, 0.0040 and 0.0040.The gene of HA, P83S, the gene of NA, N248D, the gene of polymerase (PA), P224S and the gene of NP, V100I and L122Q were found to mutate in all the samples. Genes of HA, NA, NP, PA, PB 2 and nonstructural protein (NS1) in severe cases showed obviously clustered evolution. The mutation of gene S128P and S203T of HA, gene R269R and D547E of PA, gene T588I of PB 2 and gene I123V of NS mainly happened in severe cases, separately counting 6, 9, 6, 7, 9 and 6 cases. The relevance between the mutation happened in S203T of HA, R269K and D547E of PA and the severeness of the cases showed statistical significance (P < 0.05). The mutations of HA gene were mainly on the Ca and Cb antigene domains. No drug resistant mutation was found on NA gene but happened on matrix protein 2 (M2 gene). None of the mutations were found on the virulence related genes.

CONCLUSIONA high homology was found between the pandemic H1N1 virus in Beijing in 2009 and the reference vaccine strain A/California/07/2009(H1N1). Mutational sites related with the severe and fatal cases were found, but not the virulence related mutation.

OBJECTIVETo evaluate the influence of Shenfu Injection (SHF) on the quality of life of patients with advanced non-small cell lung cancer (NSCLC) receiving chemotherapy.

METHODSA total of 133 patients with NSCLC receiving at least two cycles of chemotherapy with taxol plus cisplatin (TP)/vinorelbine plus cisplatin (NP) or gemcitabine plus cisplatin (GP) were randomized into SHF pre-treatment group (with SHF given only in the first cycle) and SHF post-treatment group (with SHF given only in the second cycle). The Quality of Life Questionnaire-Core 30 (QLQ-C30) and the Functional Living Index-Cancer (FLIC) were used to evaluate the quality of life of the patients after the treatments.

RESULTSBoth of the groups showed improved quality of life after the treatments (P<0.01), but the improvements were more obvious in SHF pre-treatment group (P<0.05). SHF showed favorable effects in relieving such adverse effects as fatigue, nausea, vomiting and diarrhea associated with the chemotherapy.

CONCLUSIONSHF can improve the quality of life in NSCLC patients receiving chemotherapies.

BACKGROUNDTumor necrosis factor-alpha (TNF-α) is a pleiotropic proinflammatory cytokine and contributes to many kinds of cardiovascular diseases via its receptors (TNFR1/TNFR2). We hypothesize that TNF-α plays a role in the pathogenesis of chronic atrial fibrillation (AF).

METHODSSixty-seven consecutive patients who were scheduled to have cardiac surgery were enrolled into the study. Thirty-one patients with rheumatic heart disease (RHD) and AF were enrolled as study group (AF group). The sinus rhythm (SR) control groups consisted of 20 patients with RHD and 16 patients with coronary artery disease (CAD). Peripheral blood sample was collected before the operation. About 5 mm(3) left atrial tissue was disserted during the operation and was separated into three parts for Western blotting, real time polymerase chain reaction (RT-PCR) and immunohistochemistry (IHC) analysis.

RESULTSCompared with the controls (RHD SR and CAD SR), the levels of TNF-α ((14.40 ± 5.45) pg/ml vs. (4.20 ± 3.19) pg/ml vs. (2.68 ± 2.20) pg/ml, P = 0.000) and its soluble receptor 1 (sTNFR1) ((1623.9 ± 558.6) pg/ml vs. (1222.3 ± 175.6) pg/ml vs. (1387.5 ± 362.2) pg/ml, P = 0.001) in plasma were higher in patients with AF. TNF-α level had positive correlation with the left atrial diameter (LAD) (r = 0.642, P = 0.000). Western blotting analysis showed that the protein levels of TNF-α (0.618 ± 0.236 vs. 0.234 ± 0.178 vs. 0.180 ± 0.103, P = 0.000) were higher in patients with AF. The RT-PCR analysis results demonstrated that the mRNA expression of TNF-α (0.103 ± 0.047 vs. 0.031 ± 0.027 vs. 0.023 ± 0.018, P = 0.000) increased in patients with AF. IHC analysis displayed that, comparing to the SR, the expression of TNF-α (0.125 ± 0.025 vs. 0.080 ± 0.027 vs. 0.070 ± 0.023, P = 0.000) increased in the AF group. The protein level and mRNA expression of TNF-α also had positive correlation with left atrium diameter (LAD) (r = 0.415, P = 0.000 and r = 0.499, P = 0.000).

CONCLUSIONSThe results revealed that TNF-α elevated in the plasma and left atrial tissue and had positive correlation with LAD in patients of chronic AF. TNF-α might involve in the pathogenesis of chronic AF.
