0.05) while those between GCT Ⅰ and the collection of GCT Ⅱ and GCT Ⅲ were significant ( P 0.05).Conclusion:The results indicated that neither the p16 positive rate nor the p27 positive rate could be used independently for defining grade of malignancy and estimating prognosis of malignant bone tumors though p16 and p27 might play important roles in the genesis of bone tumors.

The X-ray radiograph, CT scan and MRI appearance of 5 patients with pathologically proven fibrous dysplasia in thoracic and lumbar spine vertebrae were retrospectively analyzed. Plain radiographs, CT scans and MR images showed the presentation of eccentric lesion with intact cortex bone and marginal sclerosis in vertebral bodies without involvement of vertebral appendix and extraosseous soft tissue. The lesion masses were round (one being oval-shaped) and radiolucent in plain radiographs and CT scans. Homogeneous long signal was observed on T1 weighted image and strongly enhanced when gadolinium was administered. On T2 weighted MRI, short signal was found in the anterior part of the mass, long signal in the posterior part, and short and slight long signal in the middle part, without partitioning and laminating change. There was a good correlation between radiological features and surgical findings. These findings may be useful to diagnose fibrous dysplasia in spine.

Objective To predict the genes that affect endometrial receptivity through the differential expression of microRNA (miRNA) in eutopic endometrial tissues during implantation window in patients with endometriosis infertility. Methods Among infertile patients that received treatments at the Center for Reproductive Medicine,Peking University Third Hospital between May and December 2013, patients with endometriosis infertility were selected as endometriosis group (among the selected 17 cases, there were 6 cases with follicular phase endometrium and 11 cases with implantation window phase endometrium), and patients with tubal factor infertility were selected as control group (among the selected 19 cases, there were 7 cases with follicular phase endometrium and 12 cases with implantation window phase endometrium). (1)Implantation window phase endometrium was selected from 3 cases in each group. Using miRNA and mRNA joint gene sequencing and database for forecast results, as well as using the negative regulatory relationship between miRNA and mRNA, the intersection of target gene that negatively correlates with miRNA expression were obtained. The co-expression network of miRNA-mRNA wae constructed. Combined with the genes associated with endometrial receptivity found through bioinformatics method, the miRNA with core regulatory functionwas found. (2) Expand sample size to 14 cases for endometriosis group and 16 cases for control group.Reverse transcription (RT)-PCR technique was utilized to detect the expression of miR-142-5p, miR-146a-5p and miR-543 in endometrial tissues, and verify miRNA microarray results. Results (1) miRNA and mRNA microarray screening results showed that, among the endometrial tissues of patients with endometriosis infertility and with implantation window phase, 6 differentially expressed miRNA were indentified, among which miR-142-5p, miR-146a-5p, miR-1281, miR-940, miR-4634 showed significantly enhanced expression and miR-543 showed significantly inhibited expression. Sixty-three differentially expressed mRNA were indentified, among which 58 mRNA such as CADM1, IL-10RA, ITGAL and LPAR5 had significantly enhanced expression. Five mRNA such as HLA-DRB1,3,4,5 and SOHLH2 showed significantly inhibited expression. Thirty-six taget genes were found in consideration of negatively correlated miRNA expression with the genes, miRNA-mRNA co-expression network were constructed. The miR-543 was found at the core of the network. Targetscan and other database predicted that miR-142-5p, miR-146a-5p and miR-543 could act on various types of endometrial receptivity molecular corresponding marker genes such as HOX10, ITGAV, ITGB3, OPN, LIF, ESR, PGR, CDH1 and MMP. (2) RT-PCR test showed that the average levels of expression of miR-142-5p and miR-146a-5p in implantation window phase endometrium in endometriosis group were 8.3 ± 10.6 and 1.9 ± 0.8 respectively;the average levels of that in control group were 1.1±0.6 and 0.9±0.4, respectively. The difference was statistically significant (P=0.027, P=0.015), and was consistent with results from miRNA microarray test. The expression of miR-543 in tissues of follicular phase endometrium in endometriosis group (2.3±1.0) was significantly higher than that in control group (1.0 ± 0.4), and the difference was statistically significant (P=0.008). However, when comparing the expression of miR-543 implantation window phase endometrium in endometriosis group (1.2±0.6) with that in control group (1.5 ± 1.0), the difference was not statistical significant (P=0.890). Conclusions There are multiple differential expressions of miRNA in the implantation window phase endometrium tissues of endometriosis infertility patients, among which miR-142-5p and miR-146a-5p show significantly enhanced expression and may affect embryo implantation by acting on a variety of endometrial receptivity marker molecules. The expression of miR-543 in implantation window phase endometrium of endometriosis infertility patients is lower than that in the follicular phase, forewarned changes in the pattern of cyclic variation of miR-543, and may be the reason for affecting endometrial receptivity.

[Objective]To analyse the imaging findings of thoracic and lumbar fibrous dysplasia and evaluate the imaging characteristics.[Method]Among 5 cases of monostotic fibrous dysplasia of thoracic and lumbar spines,4 were imaged with CT scaning,2 with MRI and 5 with X-ray.All materials were analysed.[Result]Each X-ray revealed a round or oval radiolucent lesion surrounded by a distinct and thick rim of sclerosis.CT showed a round or oval low-density lesion with a high-density borderline between the lesion and normal vertebral bone tissue.Bone cortex remained intact in all cases.The lesion showed homogeneous long T1 signal on T1WI and hypo-or isointensity signal on T2WI.There was a characteristic hypointensity loop surrounded the lesion on T1WI,T2WI and PdWI.The lesion was demonstrated obviously in the contrast enhancement of scanning.[Conclusion]Monostotic fibrous dysplasia of thoracic and lumbar spine shows distinctive imaging characteristics that are different from dysplasia of limb bone or skull.These characteristics are decisive in the diagnosis of the lesion.

BACKGROUND:Transplanted neural stem cel s can survive, proliferate and differentiate into neurons and/or glial cel s in the host, thereby promoting partial function recovery in the host.
OBJECTIVE:To study the therapeutic effects of neural stem cel transplantation on cerebral palsy rats. METHODS:Twenty-four rats were randomly divided into three groups:control group, model group and transplantation group. Animal models of cerebral palsy were made in the latter two groups. One week after modeling, rats in the transplantation group were injected 1 mL stem cel suspension (1×105) via the jugular vein, and rats in the control and model group were given the same volume of normal saline. Toe distance, step length and elevated body swing test in rats were detected, and histopathological changes in the rat brain were observed 3 weeks after transplantation.
RESULTS AND CONCLUSION:In the model group, the toe distance and step length of the front left palm were significantly lower than those of the front right palm (P<0.05). Compared with the model group, the toe distance and step length in the transplantation and control groups were significantly increased (P<0.05). In the elevated body swing test, rats in the model group presented with asymmetric swing of the
body, but rats in the other two groups exhibited symmetric swing of the body (P<0.05). Additional y, the ratio of right to left hemispheric areas was significantly higher in the transplantation and control groups compared with the model group (P<0.05). In conclusion, neural stem cel transplantation via the jugular vein can improve brain function and restore motor function in rats with cerebral palsy.

Background:Functional gastrointestinal disorders(FGIDs)is a common disease of digestive system which severely affects the quality of life. Recently,more and more attentions have been paid to the relationship between FGIDs and psychological factors. Aims:To investigate the relationship between FGIDs and psychological factors and related treatment. Methods:A total of 270 patients with FGIDs admitted from Sept. 2013 to Sept. 2014 at Anhui No. 2 Province People’s Hospital were enrolled. Hamilton Anxiety Scale(HAMA)and Hamilton Depression Scale(HAMD)were used to evaluate the mental state of patients,and symptom severity of digestive system was scored. Patients with psychological abnormalities received conventional therapy to relieve digestive symptoms,and those who failed from conventional therapy were assigned into refractory group and others were assigned into response group. Patients in refractory group were further divided into conventional therapy group and combined therapy group for receiving paroxetine in addition to conventional therapy. Results:The rates of anxiety and depression were 61. 5%(166 / 270)and 57. 0%(154 / 270),respectively. The scores of HAMA and HAMD were positively correlated with the score of digestive symptoms(r = 0. 585,P < 0. 01;r = 0. 584,P <0. 01)in patients with anxiety and depression in response group. The scores of HAMA,HAMD and digestive symptoms in response group after conventional therapy were significantly decreased(P < 0. 05),while the scores of HAMA and HAMD in refractory group after therapy were significantly higher than those in response group before therapy(P < 0. 05). The scores of HAMA,HAMD and digestive symptoms in combined therapy group were significantly lower than those in conventional therapy group(P < 0. 05). Conclusions:Relationship is found between FGIDs and psychological factors,and antidepressants might contribute to the amelioration of symptoms of FGIDs.
