Tumor has become the major reasons cause of death,and its vaccine has become the effective tracts of treatment and prevention by enhancing the immune response of patients.However,most vaccines which are recombination subunit protein antigens are poorly immunogenic and difficult to induce a robust immune response in patients with compromised immune systems,resulting in poor marketing approval.The core component of the vaccine adjuvant can greatly enhance the strength,speed and duration of the immune response,thus becoming the key to the development of an ideal tumor vaccine.Most tumor vaccines are combined with tradition adjuvant such as aluminum,MF59 and AS adjuvant,but their products and patents are monopolized by large foreign companies.We found that natural adjuvants have many unique advantages,such as good biocompatibility and biodegradability,promoting the maturation of dendritic cell and the secretion of immune cytokines,significantly enhancing the tumor vaccine immune response,etc.In this paper,the application and future development of natural polysaccharides,saponins,flavonoid and plant virus-like particles in cancer vaccines were reviewed,which may lay a solid foundation for the development of the original and innovative adjuvants with domestic independent intellectual property rights.

Objective To explore the role and mechanism of tumor necrosis factor ligand -related molecule 1A (TL1A) in chronic experimental colitis associated intestinal fibrosis .Methods The model of chronic experimental colitis-associated intestinal fibrosis was induced by dextran sodium sulfate (DSS).The mice with high TL1A (L-Tg) expression in lymphoid cells and wild -type mice with the same genetic background were divided into wild type control group, wild type DSS group, transgenic control group and transgenic DSS group.The changes of body mass, length of colon, disease activity index (DAI) and colonic pathological score were compared among different groups .The degree of colonic inflammation was evaluated by Hematoxylin -Eosin (H-E) staining.The degree of intestinal fibrosis was assessed by Masson staining and Sirius red staining .The expression of vimentin, αsmooth muscle actin ( α-SMA), type Ⅰ collagen, Ⅲ collagen and transforming growth factor-β1 ( TGF-β1 ) /Smad3 in colon tissue was examined by immunohistochemistry .T test was performed for statistical analysis.Results The body mass of the transgenic DSS group decreased by (9.6 ± 1.8)%, which was more than wild-type DSS group (6.2 ±1.3)%, the difference was statistically significant (t =3.751, P <0.01).The DAI score and colonic pathological score of transgenic DSS group were both higher than those of wild-type DSS group (7.33 ±0.58 vs.6.00 ±1.00, and 14.00 ±1.05 vs.11.75 ±0.50, respectively), and the differences were statistically significant (t =2.818 and 4.739, both P <0.05).The results of Masson staining and Sirius red staining showed aggravation of intestinal fibrosis .The results of immunohistochemical staining showed that the cumulative positive absorbance values of vimentin , α-SMA, TGF-β1 and Smad3 of wild-type DSS group were lower than those of transgenic DSS group (0.650 ±0.050 vs. 0.800 ±0.020, 0.390 ±0.040 vs.0.600 ±0.040, 0.550 ±0.040 vs.0.730 ±0.040, 0.590 ±0.020 vs. 0.830 ±0.040), and the differences were statistically significant (t =6.823, 9.093, 7.794 and 10.390, all P <0.01).Conclusion TL1A may promote the proliferation and activation of fibroblasts through TGF -β1 /Smad3 pathway, leading to the genesis and development of experimental colitis associated intestinal fibrosis .

Objective:To explore the prevalence and risk factors of thyroid diseases in the physical examination population of Hohhot.Methods:From July 2017 to July 2018, 3 100 health examinees from Inner Mongolia National Examination Medical Center were selected as subjects for questionnaire survey, thyroid function test and thyroid ultrasound examination; a multinomial logistic regression model was used to analyze the relationship between relevant investigation factors and different types of thyroid diseases (simple thyroid nodules, simple thyroid dysfunction, and thyroid dysfunction with nodules).Results:Among the 3 100 healthy examinees, there were 2 885 effective responders, including 743 males and 2 142 females, aged (46.23 ± 12.32) years; the simple thyroid nodules, simple thyroid dysfunction, and thyroid dysfunction with nodules were 909, 648, and 619 cases, respectively, and the detection rates were 31.51%, 22.46%, and 21.46%, respectively. Logistic regression analysis results showed that age [35 - 54 years old: odds ratio ( OR) = 1.30, 95% confidence interval ( CI): 1.01 - 1.68; ≥55 years old: OR = 2.30, 95% CI: 1.68 - 3.14, P < 0.05], gender ( OR = 1.65, 95% CI: 1.32 - 2.07, P < 0.05), obesity ( OR = 1.35, 95% CI: 1.08 - 1.70, P < 0.05), and mental stress [significant: OR = 1.64, 95% CI: 1.09 - 2.48; some: OR = 1.54, 95% CI: 1.02 - 2.32, P < 0.05] were the risk factors affecting the occurrence of simple thyroid nodules. The age (35 ~ 54, ≥55 years old), gender, bad mood (a little), and mental stress (significant) were risk factors that affected the occurrence of simple thyroid dysfunction; eating high iodine food was its protective factor. The age (35 ~ 54, ≥55 years old), gender, obesity, and thyroid family genetic history were risk factors for thyroid dysfunction with nodules; the consumption of iodized salt was its protective factor. Conclusions:Older women are high-risk groups for thyroid diseases. Obesity, bad mood, mental stress will increase the risk of the disease. Daily consumption of iodized salt and moderate consumption of high iodine food can reduce the risk of the disease.

Objective To observe the value of multimodal imaging for diagnosis of cardiac space-occupying lesions.Methods Data of 70 patients with cardiac space-occupying lesions who underwent echocardiography and cardiac CT(CCT)were retrospectively analyzed,among them 35 also underwent cardiac MRI(CMRI).The value of multimodal imaging for diagnosis of cardiac space-occupying lesions were explored according to the results of surgical pathology or clinical diagnosis.Results Among 70 cases,benign tumors were confirmed by surgical pathology in 43 cases,while malignant tumors were confirmed by surgical pathology in 3 cases and clinically diagnosed in 1 case.Meanwhile,non-tumor-occupying lesions were clinically diagnosed in 23 cases,all obviously shrunken after treatments.Among 70 cases,echocardiography correctly diagnosed 57 cases,misdiagnosed 8 cases and unclearly diagnosed 5 cases,with diagnostic accuracy rate of 81.43%(57/70).CCT correctly diagnosed 63 cases,misdiagnosed 4 cases but missed 3 cases,with diagnostic accuracy rate of 90.00%(63/70).CMRI outcomes in all 35 cases were consistent with surgical pathologic results,with diagnostic accuracy rate of 100%(35/35).Conclusion Multimodal imaging might provide objective evidences for diagnosis and treatment of cardiac space-occupying lesions.

OBJECTIVETo observe the biological characteristic and the prognoses in patients with acute erythroleukemia (AEL).
METHODSThe results of 167 patients with newly diagnosed AEL, from January 2003 and June 2013 in the First Affiliated Hospital of Soochow University, were reviewed by MICM.
RESULTSFlow cytometry analysis indicated that CD13(96.1%), CD33(95.1%), CD117(87.4%) and CD34 (79.4%) were highly expressed in AEL. 56 of 148 (37.8%) AEL patients had a variety of cytogenetic abnormalities, 27 of 148(18.2%) patients were complex karyotype (abnormalities involving 3 or more chromosomes), the abnormalities of chromosomes 3, 5, 7 and 8 were more frequently involved and the most common one was +8, accounting for 35.7% of all abnormal karyotype, followed by 5q- (17.9%). Mutation analysis showed CEBPA mutation ratio of AEL patients was 44.0% (11/25), that of NPM1 as 15.4% (4/26). Initial induced remission rate of AEL was 56.6% (30/53), compared by 33.3% (4/12) of MDSM6. Survival analysis showed that the overall survival in female was better than that in male (P=0.047). The overall survival time of transplantation group is significantly longer than chemotherapy group (P=0.000). The OS of 13-39 years old group was the best, 40-49 years old group took second place, >50 years old group appeared to be the worst.
CONCLUSIONAEL had its own unique biological features, and allogeneic hematopoietic stem cell transplantation could significantly improve its poor prognosis.
