Objective To investigate the association between genetic polymorphisms of ERCCl-C8092A and susceptibility to liver cancer, as well as the gene-environmental interaction on the etiology of liver cancer in Fuzhou. Methods A case-control study was conducted to collect the information on environmental exposure while genetic polymorphism of ERCC1 was analyzed by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. General relative risk regression models were further applied to fit the interaction between genetic polymorphisms of ERCC1-C8092A and the environmental factors of liver cancer. Results ERCC1-C8092A variant genotypes were associated with significant increasing risk of liver cancer adjusted odds ratio (OR= 3.789,95%CI:2.792-5.142 ), compared to the wild-type homozygote. Data from the analysis of interaction showed that genetic polymorphism of ERCC1-8092A appeared superadditive interaction with drinking pond-ditch or with hepatitis B, and super-multiplicative interaction with eating moldy food. Conclusion The point mutation in ERCC1-8092A was possibly susceptible to liver cancer, and related synergistically with other risk factors in hepatocelluar carcinogenesis in Fuzhou.

The aim of this study was to investigate the effect of Bu-Shen-An-Tai recipe (BSATR) and its two components (Bushen recipe, and Huoxue recipe) on endometrial morphology during peri-implantation in superovulated mice. Mice were randomly divided into five groups, including the normal (N), model (M), Bushen (BS), Huoxue (HX) and Bu-Shen-An-Tai (BH) groups. The uteri were collected on day 4 of pregnancy, and the endometrium thickness, microvessel density (MVD) and number of pinopodes observed. Compared with the M group, the endometrial thickness in the BS, HX and BH groups was significantly increased and there was a significant difference in endometrial thickness between the BS and the BH groups. The mean MVD was significantly lower in the M group than in the N group, and there was a significant increase in MVD in the BS, HX and BH groups as compared with the M group. Compared with the M group, the pinopode scores in the endometrium were significantly increased in the HX and BH groups; and the BS group had significantly higher pinipode scores than the HX and BH groups. In conclusion, the results of the present study demonstrated that the recipes (Bushen, Huoxue and BSATR) could improve the endometrial environment by regulating the endometrial thickness, MVD and the number of pinopodes at the window of implantation. Moreover, the Huoxue recipe and the BSATR were more efficient than the Bushen recipe, with the BSATR tending to have the most beneficial effects.

Objective: To investigate the effect of moxibustion at Shenque (CV 8) on fatigue in rats with chronic exercise-induced exhaustion. Methods: Thirty male Sprague-Dawley (SD) rats were randomly divided into a blank group, a model group and a moxibustion group, 10 rats in each group. Except rats in the blank group, the remaining rats were subjected to create long-term exhaustion models by repeated swimming. After successful modeling, rats in the moxibustion group received mild moxibustion at Shenque (CV 8) for 15 min, once every other day with a total of 10 times. Rats in the model group and the blank group did not receive moxibustion. At the end of the treatment, the exhausted times, and the body weight of rats before and after the experiment were compared among groups. The levels of blood malondialdehyde (MDA) and urea nitrogen (BUN), as well as the activities of aspartate transarninase (AST), alanine aminotransferase (ALT) and lactate dehydrogenase (LDH) were also measured by the automatic biochemical analyzer, 24 h after the exhausting excise. Results: The 10th swimming time was significantly longer in the moxibustion group than that in the model group (P<0.01). The increase rate of the body weight was lower in the rats of the moxibustion group than that in the model group before the 7th and the 10th exhausting excise (P<0.05, P<0.01). The levels of serum MDA and BUN, as well as the activities of AST, ALT and LDH in the model group were higher than those in the blank group (all P<0.01). The levels of serum MDA and BUN, as well as the activities of AST, ALT and LDH in the moxibustion group were lower than those in the model group (P<0.01). Conclusion: Moxibustion at Shenque (CV 8) can decrease the serum levels of MDA and BUN, as well as activities of AST, ALT and LDH in the long-term fatigue rats, thus to improve the symptoms of fatigue.

BACKGROUNDHereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disease characterized by recurrent epistaxis, mucocutaneous telangiectasia, and arteriovenous malformations. The efficacy of traditional treatments for HHT is very limited. The aim of this study was to investigate the therapeutic role of thalidomide in HHT patients and the effect in FLI-EGFP transgenic zebrafish model.

METHODSHHT was diagnosed according to Shovlin criteria. Five HHT patients were treated with thalidomide (100 mg/d). The Epistaxis Severity Score (ESS), telangiectasia spots, and hepatic computed tomography angiography (CTA) were used to assess the clinical efficacy of thalidomide. The Fli-EGFP zebrafish model was investigated for the effect of thalidomide on angiogenesis. Dynamic real-time polymerase chain reaction assay, ELISA and Western blotting from patient's peripheral blood mononuclear cells and plasma were used to detect the expression of transforming growth factor beta 3 (TGF-β3) messenger RNA (mRNA) and vascular endothelial growth factor (VEGF) protein before and after 6 months of thalidomide treatment.

RESULTSThe average ESS before and after thalidomide were 6.966 ± 3.093 and 1.799 ± 0.627, respectively (P = 0.009). The "telangiectatic spot" on the tongue almost vanished; CTA examination of case 2 indicated a smaller proximal hepatic artery and decreased or ceased hepatic artery collateral circulation. The Fli-EGFP zebrafish model manifested discontinuous vessel development and vascular occlusion (7 of 10 fishes), and the TGF-β3 mRNA expression of five patients was lower after thalidomide therapy. The plasma VEGF protein expression was down-regulated in HHT patients.

CONCLUSIONSThalidomide reverses telangiectasia and controls nosebleeds by down-regulating the expression of TGF-β3 and VEGF in HHT patients. It also leads to vascular remodeling in the zebrafish model.

Growth suitability as assessment indicators for medicinal plants cultivation was proposed based on chemical quality determination and ecological factors analysis by Maxent and ArcGIS model. Notopterygium incisum, an endangered Chinese medicinal plant, was analyzed as a case, its potential distribution areas at different suitability grade and regionalization map were formulated based on growth suitability theory. The results showed that the most suitable habitats is Sichuan province, and more than 60% of the most suitable areawas located in the western Sichuan such as Aba and Ganzi prefectures for N. incisum. The results indicated that habitat altitude, average air temperature in September, and vegetation types were the dominant factors contributing to the grade of plant growth, precipitation and slope were the major factors contributing to notopterol accumulation in its underground parts, while isoimperatorin in its underground parts was negatively corelated with precipitation and slope of its habitat. However, slope as a factor influencing chemical components seemed to be a pseudo corelationship. Therefore, there were distinguishing differences between growth suitability and quality suitability for medicinal plants, which was helpful to further research and practice of cultivation regionalization, wild resource monitoring and large-scale cultivation of traditional Chinese medicine plants.

OBJECTIVETo evaluate the prognostic factors in treating primary liver cancer (PLC) patients by Pi-strengthening and qi-regulating method (PSQRM), thus providing evidence and optimizing Pi-strengthening and qi-regulating program.

METHODSClinical data of 151 PLC patients treated by PSQRM at Oncology Department, Guangdong Provincial Hospital of Traditional Chinese Medicine from May 2007 to March 2009 were retrospectively analyzed. The univariate analysis was determined to analyze possible prognostic factors. Selected key factors were introduced into the COX proportional hazard model, and multivariate analysis was carried out.

RESULTSThe 1-year survival rate was 21.85%, the median survival time was 6.80 months, and the mean survival time was 8.98 months. The univariate analysis showed that Chinese medicine (CM) syndrome types, clinical symptoms at the initial diagnosis, ascites, tumor types, ratios of foci, portal vein tumor thrombus, intrahepatic metastasis, a-fetoprotein (AFP) levels, total bilirubin classification, albumin classification, Child-Pugh classification, and domestic staging of liver cancer were significant prognostic factors (P < 0.05). The statistic data of multivariate analysis indicated that CM syndrome types, ascites, tumor types, portal vein tumor thrombus, AFP levels, Child-Pugh classification, and domestic staging of liver cancer were independent factors influencing prognosis (P < 0.05).

CONCLUSIONThe prognosis of PLC treated with PSQRM is determined by multiple factors including CM syndrome types, ascites, tumor types, portal vein tumor thrombus, AFP levels, Child-Pugh classification, and domestic staging of liver cancer.

OBJECTIVETo investigate whether CYC116 can potentiate matrine-dependent growth inhibition and apoptosis in multiple myeloma (MM) cells.

METHODSThe dose response relationship of matrine to dexamethasone-resistant and dexamethasone-sensitive MM cells was first established. Myeloma RPMI8226 cells were treated with matrine alone or combined with CYC116 for 24 h. Cell proliferation was measured using an MTT assay and apoptosis induction was evaluated by flow cytometry. Activation of the caspase pathway and expression of apoptosis regulator proteins were detected by Western blotting.

RESULTSMatrine significantly induced growth arrest and apoptosis in both drug-resistant and drug-sensitive MM cells. Treatment with the combination of matrine and CYC116 had a stronger cytotoxic effect on MM cells than did single drug treatments. Enhanced apoptosis observed following the combined treatment of matrine and CYC116 was associated with higher levels of activation of caspase-9, caspase-3, and poly adenosine diphosphate ribose polymerase (PARP) and down-regulation of the anti-apoptotic proteins Bcl-2 and Mcl-1 and the signaling proteins p-Akt and nuclear factor κB (NF-κB).

CONCLUSIONCYC116 enhances the growth inhibitory and apoptotic effects of matrine on MM cells.
