The liver is one of the most common metastatic sites in patients with breast cancer. Systemic therapy is the standard treatment for breast cancer with liver metastasis, but the results are far from satisfaction. A distinctive subset of metastatic breast cancer is oligometastatic disease. Local therapy including metastasectomy, radiofrequency ablation and radiation therapy combined with systemic therapy can provide survival beneift. This review introduced the latest research results of local therapy in liver oligometastases of breast cancer.

The pathogenesis of malignant lymphoma has been an important topic in tumor research ,but it is still unclear.Recent clinical studies showed that the expression level of Toll -like receptor 4(TLR4)was signif-icantly high in mantle cell lymphoma tissue and a variety of lymphoma cell lines .At the same time,the TLR4 ex-pression level was correlated with prognosis .The Role of TLR4 in malignant lymphoma for occurrence and devel-opment is reviewed in this article ,which may elucidate the pathogenesis and provide a new basis for the therapy of lymphoma.

Objective To investigate the morphological changes during the development and aging of C57/BL6 mouse hippocampus.Methods Serial sections and stereology were used to quantitatively analyze the development of C57/BL6 mouse hippocampus at different growth stages.Results Hippocampus primordium first appeared at embryonic day 12(E12d).A "C" outline could be seen in the pyramidal layer of Ammon's horn(CA),and the extra-arm's blanket of the dentate gyrus(DG)'s granular layer formed at E18d.After birth,CA developed and maturated gradually.The blanket of DG's granular layer formed at postnatal day 7(P7d).At P21d,the inner arm's thickness of DG's granular layer was equal to that of the extra-arm,and the subgranular layer was present until month 15(15M).The increase of the volume of hippocampus,CA,DG and CA's layers was slow before P7,became fast from P7d to P14d and slowed down again after P14d,but became stable after 3M.Conclusion Mouse hippocampus is formed at E12 and becomes basically mature at month 3.The volume of aging mouse hippocampus has no obvious changes.

Objective:To explore the effect of bilingual teaching applied to the classes of histology and embryology.Methods The bilingual teaching was tentatively preformed in a part of the undergraduates in our school during their classes of histology and embryology.Results The effect of bilingual teaching was obviously superior to the traditional one.The theory examination scores and the ability of reading and using professional English were higher in the class which employed the bilingual teaching than in the control ones.Some students thought that the bilingual teaching could mobilize their activities.Conclusion The application of bilingual teaching in Histology and Embryology has a positive significance to improve the quality of teaching.

Objective To investigate the effect of rosiglitazone (ROS),a peroxisome poliferator- activated receptor (PPAR)?ligand,combined with all-trans retinoic acid (ATRA) on anti-angiogenesis of transplanted gastric cancer in nude mice,and to explore the mechanism of anti-angiogenesis prelimina- rily.Methods The model of xenograft tumor in nude mice were established by inoculating human gastric cancer cells line MGC803 (lower differentiated) into the back of nude mice subcutaneously.The cancer- bearing nude mice were divided randomly into 5 groups:group 1 (n=6) with no treatment;ROS treat- ment (group 2,n=6),ROS combined ATRA treatment including:low dose treatment (group 3,n= 6),moderate dose treatment (group 4,n=6) and high dose treatment (group 5,n=6).After treated for forty days,the volume change of tumor and tumor inhibition rates were observed.The expression of CD34,vascular endothelial growth factor (VEGF) in grafts were detected by immunohistochemical and calculated the difference of MVD.The mRNA expression levels of VEGF,HIF-l?were detected by RT- PCR assay accordingly.Results①The volume of tumor was significantly decreased in ROS treatment group compared with group 1 (P＜0.01).The tumor inhibition rates of group 2 were similar to group 3 (P＞0.05).With the increasing of the dose of ROS the tumor inhibition rates were increased.They were dose-dependent in specified dose-range.②ROS could inhibit angiogenesis of xenograft tumor and depress expression of mRNA of VEGF and HIF-l?.When ROS combined with ATRA,the increasing of dose of ROS,inhibiting angiogenesis of tumor and depressing expression of mRNA of VEGF and HIF-l?were found (P＜0.05).Conclusion ROS (25 mg?kg?2 d~(-1)) can inhibit the growth of tumor,and ROS combined with ATRA can further inhibit the growth of tumor,which may be through the path of PTEN by inhibiting the angiogenesis of tumor

Objective To study the sensitivity and specificity of oligoclonal bands (OCBs) and intrathecal IgG synthesis rate (IgG Syn) for diagnosis of multiple sclerosis (MS) and the correlation between qualitative and quantitative indices.Methods Albumin and IgG concentrations in the cerebrospinal fluid (CSF) and serum from 30 patients with MS, 40 with other nervous system inflammatory diseases (NID) and 22 with nervous system noninflammatory diseases (NNID) were determined by rate nephelometry method. OCBs in the CSF were detected using isoelectric focusing combined with silver staining, and IgG Syn was calculated. The sensitivity, specificity and positive result likelihood ratio (PRLR) were analyzed.Results There were no significant difference in the abnormal rate of OCBs and IgG Syn between MS group and NID group. When MS and NID groups were compared with NNID group, the difference was extremely significant (all P

Objective　To determine the sensitivity and specificity of using the computer-photoscreener and non-cycloplegic retinoscopy in the detection of amblyopiogenic factors in nine to fifty months old infants.Methods　Three hundred children whose ages range from nine to fifty months were screened with the computer-photoscreener and non-cycloplegic retinoscopy. With a masked standardized clinical assessment as the standard, an overall comparison of the results obtained with the two techniques revealed a sensitivity and specificity. Photoscreen images on the computer monitor screen were reviewed and analyzed immediately by two independent observers for indicators of amblyopiogenic risk factors. Simultaneously, the results were compared to the findings of a full ophthalmologic examination.Results　The computer-photoscreener revealed a sensitivity of 94.2% and specificity of 90.1%, and the non-cycloplegic retinocopy revealed a sensitivity of 85.7% and specificity of 81.1% for the detection of amblyopiogenic risk factors, including hyperopia (+2.75 D or more), myopia (-1.50 D or more), astigmatism (2.00 D or more),anisometropia (2.00 D or more), ocular misalignment (5 degrees or more), and media opacity (1.5mm or more). Conclusion　The computer-photoscreener offers an opportunity to identify problems that limit vision, and could provide a feasible and sufficiently reliable screening technique in infants and preschool children who can be screened successfully for amblyopiogenic risk factors.

Objective To evaluate the advantage and clinical value of javanica oil emulsion injection combined with radiotherapy for esophageal carcinoma. Method Randomized controlled trials (RCTs) concerning javanica oil emulsion injection combined with radiotherapy for esophageal carcinoma were made on electronic databases of CBM, CNKI, Wangfang, VIP and PubMed from 1990 to February 28, 2015. Quality of the included RCTs was assessed by Jadad scoring , and Meta-analyses were performed by RevMan5.3 software. Results Seven RCTs involving 575 patients were included in Meta-analysis. All studies were in low quality. The results of Meta-analyses showed that Javanica oil emulsion injection combined with radiotherapy for esophageal carcinoma, compared with control groups, could increase the recent curative effect (P < 0.000 01) and improve the quality of live (P = 0.000 8), decrease the hematologic toxicities (P = 0.03) and the incidence rate of radioaction esophagitis (P = 0.02), but not enough evidence was found to prove that it can enhance survival rate (P = 0.25). Conclusions The results of Meta-analysis indicate that javanica oil emulsion injection may have therapeutic effects on the treatment of esophageal carcinoma. Yet the effects of javanica oil emulsion injection still need to be confirmed by large multi-center randomized controlled trials.
