BACKGROUND:When peri-implantitis occurs, the levels of interleukin-17 in the peri-implant sulcular fluid and soft tissues are significantly increased, and there is a positive correlation with the depth of the peri-implant probing. However, because of the dual effects of bone absorption and protection, the function of interleukin-17 in peri-implantitis remains controversial, which should be further studied. OBJECTIVE:To retrospectively analyze the correlation between peri-implantitis and interleukin-17. METHODS: The first author searched Wanfang, CNKI and Medline databases from 1991 to 2014 by using key words of “dental implants, peri-implantitis, periodontitis, Th17 cels, interleukin-17, cytokines” in Chinese or English. The functions of bone destruction and protection of interleukin-17 in peri-implantitis were reviewed, and interleukin-17 expression and correlation with the peri-implantitis were detected. RESULTS AND CONCLUSION:According to the inclusion and exclusion criteria, 46 articles from 241 articles are selected. The results show that, noninvasive detection of the variation of interleukin-17 levels in peri-implant sulcular fluid or blood is conducive to the monitoring of early diagnosis and treatment of peri-implantitis. At present, most researches show the relationship between interleukin-17 and peri-implantitis, and there is a positive correlation between interleukin-17 and peri-implant probing depth. But other researches suggest that interleukin-17 acts as protector for bones, and there is no statistic significance in the level of interleukin-17 receptor gene in chronic peri-odontitis and healthy subjects. Therefore, the correlation between peri-implantitis and interleukin-17 remains to be further studied.

Objective To provide an ideal animal model for exploring the pathogenesis and experimental treatment of malignant melanoma in the small intestine.Methods Fresh tissue of lung metastatic lesions from patients with malignant melanoma of the smallintestine were transplanted into mucosa of the small intestine in nude mice.After 4 times of screening.the tissue of the lung metastatic lesions from the nude mice were transplanted into the small intestine of additionat nude mice.Tumorgenecity and metastasis of transplanted tumors were observed,and were analyzed by morphology,karyotype and flow cytometry.Results A lung metastatic model of human primary malignant melanoma of the small intestine in nude mice was successfully constructed and named HSIM-0601.Massive melanin granules and melanin complex were seen in cytoplasm of tumor cells.Immunohistochemical straining of S-100 and HMB-45 were positive.The number of chromosome was between 57 and 59.DNA index was 1.49.HSIM-0601 was passed for 26 generations.A total of 173 nude mice were used for tumor transplantation.The growth rate of the transplanted tumors and resuscitation rate of liquid nitrogen cryopreservation were both 100%.In HSIM-0601.lung metastasis rate was 100%(173/173)and lymph node metastasis rate was 61.3%(106/173).Conclusions The HSIM-0601 successfully mimics the natural clinicopathologic course of patients with primary small intestinal melanoma,and provides an ideal animal model for research on pathogenesis,metastasis and experimentM therapy of malignant lymphoma in the small intestine.

Objective To investigate the differences in dosimetry between conformal radiotherapy (CRT),field-in-field intensity-modulated radiotherapy (FIF-IMRT),and intensity-modulated radiotherapy (IMRT) after breast-conserving surgery for left-sided breast cancer.Methods A total of 31 patients who underwent breast-conserving surgery for left-sided breast cancer were randomly selected,and the plans for CRT,FIF-IMRT,and IMRT were developed.The dose-volume histogram (DVH) was used for self-control study,and the non-parametric test was used to compare the differences in target volume and doses to organs at risk (OARs).Results All the three methods met the requirements of the prescribed doses.The CRT group had a higher V105 of the target volume and higher heart V30 and Dmax (P=0.000,0.000,0.000).The IMRT group had higher V5 and Dmean (P=0.000,0.000),as well as a higher lung V5 and a lower lung V40 (P=0.000,0.000).The FIF-IMRT group had the lowest Dmean (P=0.000),and the IMRT group had significantly higher Dmean and Dmax of the right lung and the spinal cord than the other two groups (P=0.000,0.000,0.000,0.000).The FIF-IMRT group had a significantly lower single hop count than the other two groups (P=0.000).Conclusions CRT has a good dose distribution in the target volume,but greatly injures the surrounding tissues.FIF-IMRT can well protect OARs and cause less damage to the device.

Objective To observe the effect of capsaicin on lipid deposition in liver cells and the expression of autophagy,to provide new ideas and targets for the study of fatty liver disease.Methods The model of nonalcoholic fatty liver disease (NAFLD) was established by inducing LGF cell line of liver primary cells with oleic acid (40 μg/mL).The experiment was divided into blank control group,oleic acid group,capsaicin group[oleic acid--capsaicin(100 μmol/L)].The level of intracellular lipid was detected by oil red O staining and triglyceride (TG) kit.Western bolt was used to detect the expression level of autophagy marker molecule p62 and LC3,and to calculate the ratio of LC3 Ⅱ/LC3-Ⅰ.Results After treated with 40 μg/mL oleic acid for 24 h,the oil red O staining showed that orange-red lipid droplets were found in the oleic acid group,but there was no obvious orange-red lipid droplet formation in the blank group,which suggesting that the NAFLD cell model was established successfully by using 40 μg/mL oleic acid in vitro.Oil red O staining was observed,the cells in the capsaicin group were significantly less than the oleic acid group,and the content of triglyceride in the liver cells was significantly lower than that in the oleic acid group(P<0.05).Western bolt test results showed that capsaicin group p62 protein levels were significantly lower compared with the oleic acid group(P<0.05),while the LC3-Ⅱ/LC3-Ⅰ ratio was higher than that of oleic acid group(P<0.05).Conclusion NAFLD model was established by inactivating LO2 cell line with oleic acid in vitro.Capsaicin stimulated NAFLD cells,upregulated the autophagy level of NAFLD cells and reduced intracellular lipid deposition,but the specific mechanism need further study.

Chinese Pharmaceutical Journal 2017;52(13):1194-1200
OBJECTIVE: Nowadays, recombinant monoclonal antibodies developed as biosimilar domains in application category for Investigational New Drug in domestic. The quality similarity should be prequalified for candidate drug to be developed as biosimilar. Here, the concept of quality biosimilarity was proposed and discussed from reviewer as well as developer. METHODS: The challenge of developing and evaluating biosimilar antibodies was emphasized. Then, the domestic sponsor's common problems were sorted out and critical quality attributes of some originator antibodies were summarized. Lastly, the reasons of holding letter or case rejected were exemplified and analyzed. RESULTS: AND CONCLUSION: The sponsor are encouraged to conduct comparing exercise by state-of-art analytical technologies to conform the quality similarity between a proposed biosimilar antibody and the originator product, the reviewers should also be very cautious to assess quality differences. Joint efforts and effective communication from researcher and reviewer are critical for promoting development of domestic biosimilar and addressing the unmet medicine need.
