Objective To identify the stem cell characteristics of human diploid cells 2BS and evaluate the potential as biological function positive cells for quality detection of stem cells.Methods Flow cytometry was applied to detect the expression levels of stem cell surface markers in 2BS cells.The staining with alizarin red S,oil red O and alcian blue was used to evaluate the ability of osteogenic,adipogenic and chondrogenic differentiation,respectively.Co-culture with lymphocytes was used to observe the effects on lymphocyte proliferation.Results Human diploid cells 2BS expressed the surface markers CD73,CD 105 and CD90 of stem cells,and possessed the potential of osteogenic differentiation and inhibiting lymphocyte proliferation.Conclusion 2BS cells have several properties of stem cells and could be the positive control for surface markers detection of stem cells by flow cytometry.

IL-8 is a cytokine which belongs to the chemotactic superfamily.It is one of the major mediators in the inflammatory response.In recent years,it was found that it had multiple functions,such as chemoattractant,potent angiogenic,and so on.The cytokine is believed to play an important role in the pathogenesis of inflammation,tumor progress and immune disease.In this review,the properties of IL-8 and highlight its roles on inflammation and tumor progress were surveied.

Extramural vascular invasion(EMVI)was defined as the presence of tumor cells within an endotheliumlined vessel beyond the muscularis propria.High-resolution MRI had 100％sensitivity and 89％specificity in identification of large(caliber greater than 3 mm)EMVI with histopathology as reference.EMVI detected by both histopathology and MRI was significantly associated with local recurrence,distance metastasis and tumor-related death in rectal cancer,which was also identified as an independent prognostic factor for 3-year tumor-free survival and overall survival.EMVI could be used as one of the risk factors,which would allow stratification of patients with rectal cancer to receive neoadjuvant chemoradiotherapy(neoCRT).Moreover,EMVI detected by high-resolution MRI was identified as an independent predictor for response to neoCRT.Tumor regression grading scale defined by high-resolution MRI could be used to evaluate EMVI regression after neoCRT.

Objective To explore the clinical application of two endometrial mechanical stimulation methods in patients with repeated implantation failure (RIF) in frozen-thawed embryo transfer (FET) cycle. Methods A total of 127 women with RIF who planned to perform FET again were included. They were separated into 3 groups: Group A (45 cases) with endometrial scratching and group B (42 cycles) with endometrial sucking within menstrual period in FET cycle, while in control group C (40 cases), no endometrial mechanical stimulation was performed. The outcomes of pregnancy were compared. Results The endometrial types of endometrial scratching group were mainly type A. The embryo implantation rate and clinical pregnancy rate in group A (27.27%, 46.67%) were significantly higher than those in group B (12.75 %, 21.43%) and group C (11.46%, 20.0%) (P <0.05). Conclusion The endometrial mechanical stimulation can improve the endometrial receptivity, compare with endometrial sucking, endometrial scratching can improve the clinical pregnancy rate of RIF patients more obviously.

Schizophrenia is a common but complex mental disorder affected by multiple factors. Forensic psychiatric assessment of schizophrenia involves evaluations on many aspects, but there is no effective biological identification index for schizophrenia. Researches indicate that dysfunction of dopaminergic neurotransmission plays an important role in the pathogenesis of schizophrenia. Our study reviews the classification, genetic structure of dopamine receptors and the recent pertinent studies between the dopamine receptors and schizophrenia and its forensic significance.

Primary biliary cirrhosis (PBC)is an autoimmune disease.Ursodeoxycholic acid (UDCA)is the only safe and effective drug for the treatment of PBC,as proved by randomized controlled clinical trials,so it is advocated as first-line therapy.Alternative therapies are urgently needed for patients with poor response to UDCA.In addition to the efficacy of UDCA,the classification of alternative and adjuvant therapies for UDCA nonresponders and the latest research progress in these therapies are reviewed;the efficacy of existing drugs and treat-ment prospects are evaluated,but more long-term clinical studies are needed to confirm the efficacy of immunosuppressants such as budes-onide and etanercept and other drugs.A number of novel molecular therapies for PBC are also undergoing clinical trials.There is currently no consensus on the medical treatment for patients with poor response to UDCA.Although studies have shown that some drugs can improve liver function and liver biochemistries,there is no definitive evidence that they improve long-term outcome.

Objective To compare differences in pathological grade,clinical classification and prognosis in patients with Henoch?Sch?nlen purpu?ra nephritis(HSPN)in each age group. Methods Totally 225 cases of patients diagnosed as HSPN and treated in the hospital were selected to ret?rospectively analyze their clinical manifestations,pathological classification and prognosis and compare the difference in pathological grade,clinical classification and prognosis by age. Results Of the concomitant symptoms of HSPN,the incidence rate of abdominal pain was the highest in pa?tients of school age. There was statistical significance in the incidence rate of gastrointestinal bleeding between each age group. Of the clinical mani?festations,proteinuria was positive correlated with the pathological type,and the difference was statistically significant(r=0.471,P<0.000 1). But there was no correlation between the count of urine red blood cells in the urine and the pathological type. There was difference in the pathological grade between each age group(H=19.194,P<0.000 1). The difference mainly showed in the pathological grade between adults,children of pre?school age and adolescents(Z=-2.702,P=0.001;Z=-3.675,P<0.000 1). There was difference in clinical classification between each age group (χ2=36.114,P<0.000 1). The difference mainly showed in clinical manifestations between adults,children of school age and adolescents(χ2=19.628,P<0.000 1;χ2=18.944,P<0.000 1). For both children and adults who had developed into chronic renal failure,the renal pathology of these patients was not significantly different. Conclusion Compared with adults,children have milder pathological types and clinical manifestations and well prognosis of HSPN,and the most important factor which affects the prognosis is pathological type and urine protein can reflect the serious?ness of pathological type.

Objective:To identify the novel intronic transcripts containing 11q13.5 HERV-W gag sequence, and explore the modulation of the transcripts on the alternative splicing of host gene PTD015. Methods:Half-nested PCR and touchdown PCR were used to amplify the target transcripts. The transcripts were cloned and sequenced. The plasmids inserted with the target transcripts were transfected into JEG3 cells and the alternative spliced mRNA levels of PTD015 were measured with real time PCR. Results:A 1 739 bp novel intronic transcript containing 755 bp 11q13.5 HERV-W gag sequence, 527 bp 5′ long terminal repeat and 457 bp sequence on the 5′-end of 11q13.5 HERV-W was identified. The intronic antisense transcripts significantly down-regulated the alternative spliced mRNA levels of PTD015. Conclusion:The intronic antisense transcripts originating from the second intron of gene PTD015 could modulate the alternative splicing of the host gene PTD015.
