Objective To explore the significance and value of Kisspeptin in the diagnosis and therapeutic evaluation for idiopathic central precocious puberty(ICPP) in girls.Methods Twenty-four girls with ICPP and 21 girls with premature thelarche(PT) who were hospitalized in the Children's Hospital of Jiangxi Province from Jun.2012 to Jan.2013 were selected as ICPP group and PT group,and 25 healthy girls were selected as healthy control group.The coagulation vein blood in ICPP girls before treatment and after 6 months treatment and PT girls and healthy girls were collected,and enzyme linked immunosorbent assay was used to detect the plasma Kisspeptin level,and t test was used to analyze the differences among the 4 groups.Results The Kisspeptin level of girls with ICPP [(1.80 ± 0.13) μg/L]was apparently higher than that of PT groups [(1.41 ± 0.10) μg/L] and healthy control group[(1.39 ± 0.13) μg/L],and the differences were statistically significant (t =10.974,14.787,all P =0.000).However,the difference of Kisspeptin between PT group and healthy control group was not statistically significant(t =10.970,P =0.095).In addition,the Kisspeptin level of ICPP girls who undewent 6-month treatment [(1.49 ± 0.15) μg/L] was significantly lower than that before treatment,and the difference was statistically significant (t =10.80,P ＜ 0.05) ;but,compared with PT group and healthy control group,there was no significant difference (t =6.32,P =0.060 ; t =7.44,P =0.214).Conclusions Kisspeptin level is related with pubertal development,and it can be used as an important evidence in ICPP diagnosis and an important parameter in ICPP therapeutic evaluation.

BACKGROUND:The lumbar interspinous device, as a kind of non-fusion technology has been extensively applied in the clinic and exerts superiority in biomechanics compared with the traditional fusion technology. With the development of prosthesis design and impanation technology, it reveals a better application prospect. OBJECTIVE:To review the biomechanics and finite element analysis of lumbar interspinous devices. METHODS:The first author retrieved the databases of CNKI, WanFang, PubMed and SpringerLink using the keywords of“lumbar spine, interspinous devices, biomechanics, finite element analysis”in Chinese and English, respectively. Researches related to the biomechanics and finite element analysis of lumbar interspinous devices were included and repeated researches were excluded. A total of 44 literatures were enrol ed for review, including 8 Chinese and 36 English literatures. RESULTS AND CONCLUSION:(1) Biomechanical y, several interpinous devices, which are commonly used in the clinic, can increase the stability of the implanted segment in sagittal alignment by limiting the range of flexion-extension, with no significant change in lateral bending and axial rotation. (2) Few studies analyze the influence of the implant size and placement on the implanted segment and on the adjacent segments. (3) Through the stress nephogram, three-dimension finite element analysis can intuitively analyze the changes of the stress distribution in the intervertebral disc, isthmus and facet joints before and after implantation. Both biomechanical studies and finite element analysis indicate that interspinous devices can share the load of the disc and facet joints, and at the same time, make no effect on the range of motion and stress of the adjacent segment. (4) In conclusion, the short-term biomechanical advantage of the interspinous devices is obvious, but further studies are needed. The finite element analysis can simulate different body physical environment, and can analyze mechanical distribution changes after implantation, which is an effective way to evaluate the mechanical mechanism of the interspinous devices.

Objective To investigate the in vitro inhibitory effect of LIGHT on human esophageal carcinoma cells. Methods LIGHT Fc expression vector was transfected into human esophageal squamous carcinoma cell line, Eca109. The inhibitory effect of LIGHT gene on cell growth was detected by MTT and cell growth curve. The expressions of LT?R and HVEM were detected by RT PCR. Results Expression of LIGHT Fc gene could inhibit Eca109 cell proliferation. The growth curve of Eca109/LIGHT was significantly lower than that of the control group in the culture medium containing 1% FCS. MTT test showed that there was significant difference in cell viability between Eca109/LIGHT and the control group ( P
