Objective To study the relationship between the adult sternum multiple measurements and the body length in Chinese Han population for the purpose of body length estimation. Methods In this article, we had surveyed 135 samples(100 males and 35 females) .The total length of the sternum, the length of the sternal manubrium and the sternal body, the maximum and minimum breadth of the sternal manubrium, the Kleinste Breite des Ma-nubrium sterni, the maximum breadth of the sternal body, the Dicke des Manubrium sterni, the thickness of the sternal manubrium,the maximum thickness of the sternal manubrium and the sternal body in Chinese Han population was measured. Multiple linear regressions for estimating the body length were obtained by the stepwise regressive mathematics. Results Five multiple linear regressions (4 for different male age groups and 1 for female group ) for body length estimation were obtained. The multiple- relationship coefficient(R) was between 0.6237 and 0.7350, and the standard deviation was between 4.5720 and 7.0348. Conclusion The body length could be estimated by the sternum measurement data.However, its accurate was not as well as estimation by the long bone measurement. The male sternum multiple measurement data was significantly different from female. The body length can not be estimated only by the length of the sternal manubrium .

Cholangiocarcinoma (CCA) is a group of solid tumors with high malignant degree and poor prognosis. Surgical resection has still been the main therapy options. Targeting therapy and immunotherapy are the main anti-tumor methods that have been paid more and more attention in recent years, especially immunotherapy. The tumor microenvironment of CCA is complex, which encompasses not only interstitial and endothelial cells, but also a large number of immune cells. In addition, the innate and adaptive immune systems also play a role. This article summarizes the immune-related studies of cholangiocarcinoma and the latest clinical trials of immunotherapy.

AIM: To observe the changes of interleukin-6(IL-6), IL-8 and tumor necrosis factor-?(TNF-?) in serum and lung at different time, and the effects of anisodamine (654-2) treatment in rats with oleic acid-induced ARDS. METHODS: The ARDS model induced by intravenous injection of oleic acid in the rat was used and levels of IL-6, IL-8, TNF-? in serum and lung tissue supernatant were measured using enzyme linked immunosorbent assay (ELISA). RESULTS: Levels of serum and lung tissue IL-6, IL-8, TNF-? in oleic acid type ARDS 4 h group were increased significantly. These cytokines in oleic acid type ARDS 8 h group were lower than that of ARDS 4 h group, but serum IL-6, TNF-? and lung tissue IL-6 were still higher than that of control group . In oleic acid type ARDS 16 h group, serum IL-6, TNF-? were lower than that of the ARDS 8 h group and serum TNF-? and lung tissue IL-6 were higher than that of control group. After 654-2 treatment, the levels of serum and lung tissue IL-6, TNF-? were decreased significantly. CONCLUSION: IL-6, IL-8 and TNF-? might play important roles in the oleic acid-induced ARDS in the rat. 654-2 might alleviate ARDS by inhibiting excess production of IL-6 and TNF-?.

Purpose To retrospectively analyze and summarize the image features of rare ovarian clear cell carcinoma (OCCC), and to provide basis for clinical diagnosis. Materials and Methods CT and MRI features of 30 cases of OCCC confirmed by pathology were retrospectively analyzed. Sixteen of all the patients underwent pre- and post-contrast CT scan. And 14 patients underwent pre- and post-contrast MRI scans. Results ① CT features: unilateral mass was revealed in 15 cases and bilateral mass was in 1 case. The maximum diameter of the mass ranged from 8 to 23.7 cm, mean (12.86±3.96) cm. One mass was irregular, 4 masses revealed incomplete capsule, and 4 masses had septa in the mass. CT value of cystic part of the mass was 20-30 HU, and which of solid part was 28-53 HU. On post-contrast CT images, the septa and solid component of the mass showed marked enhancement and delay enhancement, while the cystic component showed no enhancement. ② MRI features: Unilateral mass was revealed in 13 cases and bilateral mass was in 1 case. The maximum diameter of the mass ranged from 9.2 to 30.0 cm, mean (14.03±4.72) cm. One mass was irregular, 2 masses revealed incomplete capsule, and 2 masses had septa in the mass. The cystic component showed heterogenous signal intensity on T1WI, and high signal intensity on T2WI. There was no enhancement on post-contrast images. The solid component showed iso-intensity on T1WI, high signal intensity on T2WI, and diffused restricted on diffusion-weighted images. There was markedly enhancement on post-contrast images. ③ Blood supply of the tumor: In 8 cases, the branch of enlarged ipsilateral ovarian artery fed the tumors. In other 16 cases, the masses were surrounded by enlarged ipsilateral ovarian vein. Conclusion The characteristic CT and MRI features of OCCC include: a cystic solid mass with complete capsule; the solid component projects into the cavity, which could be hypervascular and marked enhanced.
