Aim To observe the analgesic effect of oxymatrine(OMT)and its mechanism.Methods A peripheral mononeuropathy was produced in adult mice by placing loosely constrictive ligatures around the common sciatic nerve.The antinociceptive effects of the OMT were assessed in mechanical allodynia and cold allodynia tests.The CAMKII inhibitor KN-93 and AIP were adopted to investigate the influence of OMT on the analgesic effect and analyze its analgesic mecha-nisms.Western blot was used to evaluate the expres-sions of tCaMKII and pCaMKII protein.Results The intraperitoneal administration of OMT (1 60,80 mg· kg -1 )increased the paw withdrawal threshold in the
mechanical allodynia test (P <0.05 ),OMT (1 60, 80,40 mg·kg -1 ,ip)remarkably decreased the paw lifts in the cold allodynia test (P <0.05).Ith KN-93 (1 .25 μg/site),AIP (0.02 μg/site)significantly en-hanced the analgesic effect of OMT (35 mg·kg -1 ) (P <0.01 ).Protein expression of pCaMKII was de-creased by OMT(1 60 mg·kg -1 ).Conclusion OMT has significant protective effects on chronic constriction injury(CCI)in mice,and the effective mechanism of OMT inhibits the expression of CaMKII receptor.

Objective To investigate the safety and clinical response of dendritic cells (DC)vaccine loaded with HLA-A2-restricted peptides MAGE-3、 Tyr、 MART-1 and GP-100 against malignant melanoma. Methods Twenty three HLA-A2 positive patients with malignant melanoma were enrolled.Peripheral blood mononuclear cells were separated into adherent cells for induction of DC loaded with four peptides. DC vaccine was administered subcutaneously once a week in inguinal region. The immunological responses and clinical responses were evaluated. Results Dendritic cell vaccination were well tolerated in all patients and there was no toxicity observed. Serum levels of IL-2, IL-12 and IFN-γincreased significantly after first vaccination and fourth vaccination. The positive rate of DTH test was 50% (5/10), and 2 fold increase of CD8+ IFN-γ+ cells were observed in 6 of 10 patients. Stable disease was observed in 11 of 23 patients, one patient had a complete metastasis regression, four patients had 50% regression of metastasis,four patients had a minor response, and disease progressed in three patients. Conclusion DC vaccines loaded with peptides MAGE-3、 Tyr、 MART-1 and GP-100 can elicit non-specific and specific immune responses, leading disease control. DC vaccine is considered one of safe and effective treatments for malignant melanoma.

Histone acetylation is a well-characterized epigenetic modification controlled by histone acetyltransferases (HATs) and histone deacetylases (HDACs). Imbalanced histone acetylation has been observed in many primary cancers. Therefore, efforts have been made to find drugs or small molecules such as HDAC inhibitors that can revert acetylation levels to normal in cancer cells. We observed dose-dependent reduction in the endogenous and exogenous protein expression levels of KAT8 (also known as human MOF), a member of the MYST family of HATs, and its corresponding histone acetylation at H4K5, H4K8, and H4K16 in chemotherapy drug gemcitabine (GEM)-exposed T24 bladder cancer (BLCA) cells. Interestingly, the reduction in MOF and histone H4 acetylation was inversely proportional to GEM-induced γH2AX, an indicator of chemotherapy drug effectiveness. Furthermore, pGL4-MOF-Luc reporter activities were significantly inhibited by GEM, thereby suggesting that GEM utilizes an MOF-mediated anti-BLCA mechanism of action. In the CCK-8, wound healing assays and Transwell ® experiments, the additive effects on cell proliferation and migration were observed in the presence of exogenous MOF and GEM. In addition, the promoted cell sensitivity to GEM by exogenous MOF in BLCA cells was confirmed using an Annexin V-FITC/PI assay. Taken together, our results provide the theoretical basis for elucidating the anti-BLCA mechanism of GEM.

ObjectiveTo explore the protective effect and mechanism of Qihong Tongluo prescription on vascular endothelial cells in rats with deep venous thrombosis (DVT). MethodSixty-six SD rats were randomly divided into a blank group (n=11) and a modeling group (n=55). The DVT model was induced in rats of the modeling group by slowing down blood flow and damaging vascular endothelium. The model rats were randomly divided into model group, aspirin group (200 mg·kg-1), and low-,medium-, and high-dose Qihong Tongluo prescription groups (6.5, 13, 26 g·kg-1) according to a random number table. Rats were treated with corresponding drugs by gavage, while those in the model group and the blank group received normal saline, once per day for 7 days. The rats were sacrificed and the abdominal aortic blood was taken. The levels of serum endothelin-1 (ET-1) and interleukin-6 (IL-6) were detected by enzyme-linked immunosorbent assay (ELISA). Hematoxylin-eosin (HE) staining was used to observe the pathological changes in vascular endothelial tissues. The ultrastructure of vascular endothelial cells was observed by the transmission electron microscope. The viability of vascular endothelial cells was detected by methylthiazolyldiphenyl-tetrazolium bromide (MTT) method,and the release level of lactate dehydrogenase (LDH) was detected by the LDH kit. The messenger ribonucleic acid (mRNA) expression of platelet-activating factor (PAF),nuclear transcription factor κB (NF-κB),Ras-related C3 botulinum toxin substrate 1 (Rac1), and Ras-related C3 botulinum toxin substrate 2 (Rac2) in vascular endothelial tissues were detected by real-time reverse transcription polymerase chain reaction (Real-time PCR). The protein expression of PAF,NF-κB,Rac1, and Rac2 in vascular endothelial tissues was detected by Western blot. ResultThe model group showed seriously damaged and swollen vascular endothelial cells with massive shedding, attachment of massive inflammatory cells, nucleus pyknosis and deformation under the electron microscope, highly swollen mitochondria, serious cytoplasmic vacuolation,and exposure of internal elastic membrane. The damage of vascular endothelium and its ultrastructure in Qihong Tongluo prescription groups and the aspirin group was improved in varying degrees. Compared with the blank group,the model group showed increased levels of serum ET-1 and IL-6,potentiated vascular endothelial cell viability, up-regulated mRNA and protein expression of PAF,NF-κB,Rac1, and Rac2 in vascular endothelial tissues,and decreased LDH release level of vascular endothelial cells (P<0.05). Compared with the model group,the aspirin group and the Qihong Tongluo prescription groups showed decreased levels of serum ET-1 and IL-6,blunted vascular endothelial cell viability,down-regulated mRNA and protein expression of PAF,NF-κB,Rac1, and Rac2 in vascular endothelial tissues,and increased LDH release level of vascular endothelial cells (P<0.05). The effect of Qihong Tongluo prescription was dose-dependent. ConclusionQihong Tongluo prescription has a protective effect on vascular endothelial cells of DVT rats and can prevent and treat thrombosis,and its therapeutic effect is presumably achieved by inhibiting the expression of PAF,NF-κB,Rac1,and Rac2 and reducing the levels of serum ET-1 and IL-6.

OBJECTIVE: To explore the effects of different primary processing methods on quality change of Polygonatum sibiricum, and to optimize primary processing method of P. sibiricum with different grades and shapes. METHODS: After processed with different drying methods, boiling method and steaming method, sulfuric acid-phenol method was used to determine the contents of indicator component P. sibiricum polysaccharide in samples. The contents of ethanol-soluble extract, water-soluble extract and total ash were investigated. The optimal primary processing methods were screened. RESULTS: After processed with different methods, the contents of polysaccharide (≥7%), ethanol-soluble extract (≥45%) and total ash (≤4%) of samples at all levels conformed to the requirements of the 2015 edition of Chinese Pharmacopoeia (part Ⅰ); from aspect of drying method, microwave drying method was better than oven drying method;for P. sibiricum with different morphologies (individual and lamellar), the quality of lamellar samples of P. sibiricum was better than that of individual P. sibiricum. As primary processing method, steaming was better than boiling. The contents of P. sibiricum polysaccharide were in relatively high level, when the steaming and boiling time of gradeless and uniformly-priced goods of P. sibiricum were 20 and 15 minutes respectively. CONCLUSIONS: By discussing the different primary processing methods, high-efficient primary processing method for the individual and lamellar samples of P. sibiricum as well as gradeless and uniformly-priced goods of P. sibiricum are preliminarily obtained, which can provide a scientific basis for the effective utilization of P. sibiricum resources.

Objective:The existed economic evaluations of cancer screening in Chinese population are almost all single-cancer focused, evidence on parallel comparison among multiple cancers is lacking. Thus, the aim of this study was, from a priority setting perspective, to compare the cost-effectiveness of six common cancers(colorectal cancer, breast cancer, liver cancer, lung cancer, esophageal cancer and stomach cancer) to facilitate policy making in future scaled-up screening in populations in China.Methods:Partially based on our previous single-cancer systematic reviews (colorectal cancer, breast cancer, liver cancer, and lung cancer), evidence of economic evaluations of cancer screening in populations in mainland China were systematically updated and integrated. The main updates include: 1) Stomach cancer and esophageal cancer were newly added to the current analysis. 2) The literature searching was extended to 8 literature databases, including PubMed, EMbase, The Cochrane Library, Web of Science, CBM, CNKI, Wanfang Data, and VIP. 3) The period of publication year was updated to the recent 10 years: January 1, 2009 to December 31, 2018. 4) The study focused on populations in mainland China. Following the standard processes of literature searching, inclusion and exclusion from previous systematic reviews, the basic characteristics, evaluation indicators and main results of the included studies were extracted. All the costs were discounted to 2017 value using the by-year consumer price index of medical and health care residents in China and presented in the Chinese Yuan (CNY). The ratios of incremental cost-effectiveness ratio (ICER) to China′s per capita GDP in 2017 were calculated (<1 means very cost-effective, 1-3 means cost-effective, >3 means not cost-effective). Given a specific indicator, the median value among all reported screening strategies for each cancer was calculated, based on which priority ranking was then conducted among all cancers when data available.Results:A total of 45 studies were included, 22 for breast cancer, 12 for colorectal cancer, 6 for stomach cancer, 4 for esophageal cancer (all conducted in high-risk areas), 1 for liver cancer and none for lung cancer (was not then considered for next ranking due to limited numbers of studies). When based on the indicator, the median ratio of cost per life-year saved to China′s per capita GDP (reported in 12 studies), the lowest ratio (-0.015) was observed in esophageal cancer among 16 strategies of 2 studies ( N=2, n=16), followed by 0.297 for colorectal cancer ( N=3, n=12), 0.356 for stomach cancer ( N=1, n=4) and 0.896 for breast cancer ( N=6, n=52, P75=3.602). When based on another commonly used ICER indicator, the median ratio of cost per quality-adjusted life-year gained to China′s per capita GDP (reported in 13 studies), the least cost was found in stomach cancer (0.495, N=3, n=8, P75=3.126), followed by esophageal cancer (0.960, N=1, n=4, P75=1.762) and breast cancer (2.056, N=9, n=64, P75=4.217). Data was not found for colorectal cancer. In addition, cost per cancer case detected was the most adopted indicator (32 studies). The median cost among all screening strategies for each cancer was 14 759 CNY for stomach cancer ( N=5, n=7), 49 680 CNY for colorectal cancer ( N=12, n=25) and 171 930 CNY for breast cancer ( N=13, n=24), respectively. Data was not available for esophageal cancer and rare for precancer cases detected. Evidence related to cost per disability-adjusted life-year gained was not available. Conclusions:At China′s national level and limited to the six cancers covered by the current study, the preliminary analysis suggests that stomach cancer and colorectal cancer were the most cost-effective target cancers and could be given priority in the future scaled-up screening in general populations. Esophageal cancer screening should be prioritized in high-risk areas. Breast cancer was also cost-effective in general but some of the intensive screening strategies were marginal. Data on liver cancer and lung cancer were too limited to conclude, and more well-designed studies and high-quality research evidence should be required. This priority ranking might be changed if other common cancers were involved analyses.
