In the past, the ways to amblyopia neural mechanism research are given priority to visual electrophysiology and so on, which express the result use two -dimensional form, these ways mainly research the functions of the state before the lateral geniculate body. For the study of optic center, animal models are used to research it. But these kinds of methods are unable to accurately detect amblyopia neural mechanisms of human beings. Vulnerable to a variety of factors, it is difficult to finish the amblyopia treatment effect evaluation. Functional magnetic resonance imaging ( fMRI ) can reflect the three-dimensional visual cortex neuron activity noninvasively and accurately, and give rise to amblyopia neural mechanism and therapeutic effect evaluation. Therefore, in this paper, the amblyopia neural mechanisms and visual center after treatment effect evaluation of fMRI research progress are summarized.

P-glycoprotein (P-gp) belongs to the member of the super-family of ATP-binding cassette (ABC) transporters. It is the 170KD glycoprotein which is the product of the MDR1 gene, located in chromosome 7q21. It is an ATP-dependent exported and oriented transporter and involved in various physiological functions as well as the transport process of many types of drugs in the body. The physiological function of P-gp is to pump the toxic metabolites out of the cell in order to reduce the accumulation of toxic products so as to protect the cells from the poison. However, in pathological condition, the drug which used to treat the disease may be pumped out of the cells by the P-gp. Therefore,the P-gp is the main cause of the multidrug resistance in clinical disease such as tumor and some neurologic diseases. The cross-resistance phenomenon is leading to poor efficacy for these diseases treatment.Panax notoginseng as the characteristic Chinese herbal medicine in Yunnan province, it has many significant effects in the treatment and prevention of many diseases such as cerebrovascular diseases. It can improve the blood hemorrheology,prevent the produce of the peroxy radical, alleviate intracellular calcium overload,treat inflammation,as well as improve the immune system function. Meanwhile, some research recently reported that it also has a considerable prospect with its multi-target and multi-channel regulation in the reversal of the MDR1 and the P-gp genes expression. This paper reviews the progress of the down-regulated expression of P-gp and MDR1 genes through different pathways, and the mechanism of Panax notoginseng and its monomer compositions on down-regulated the expression of the P-gp and MDR1 genes.

Objective To explore the role of p170, MRP, bcl-2 in clinical drug- resistance and their correlation. Methods There are 44 acute leukemia(AL) patients, among them ANLL is 29, ALL is 15.The expression of p170, MRP, bcl-2 were detected. At last, the patients were divided into two groups: CR and NR according to efficacy after two periods standard chemotherapy. Results Overexpression of p170, MRP,bcl-2 were found in AL (P ＜0.05). The expression of p170 and MRP were lower in CR group than that in NR groups in AML and ALL; there were 22 of 24 patients expressed one or two proteins in NR groups and the expression of p170 in patients was concordant with that of MRP to certain extent (P ＜0.01). The overexpression of bcl-2 was related with the worse prognosis. The expression of bcl-2 was lower significantly in CR group than in CR and NR (P＜0.05). Conclusion p170, bcl-2, MRP are all associated with clinical MDR. High expression of these proteins is an unfavorable factor to prognosis. The expression of MRP and p170 showed coincidence, but showed no significance with expression of bcl-2 in untreated patients, it indicated that the drug-resistance mediated by p170 was different from bcl-2.

Ebosin is a novel exopolysaccharide produced by Streptomyces sp.139 with remarkable activity against rheumatic arthritis in vivo. In this paper, we reported effects of Ebosin on the inflammatory cytokines including interleukin-1beta (IL-1beta), interleukin-6 (IL-6) and tumor necrosis factor alpha (TNFalpha) in THP-1 cells. With the special fluorogenic peptide as substrates, the enzymatic activities of interleukin-1beta converting enzyme (ICE) and TNFalpha-converting enzyme (TACE) were inhibited by Ebosin separately. Using the real-time reverse transcription polymerase chain reaction (real-time PCR), the mRNA synthesis of the three cytokines were identified decline separately by Ebosin. The secretion quantum of three cytokines in THP-1 cells with Ebosin was lower than that of normal THP-1 cells determined by ELISA assay and Western blotting. All of these results showed that Ebosin has remarkably suppressed synthesis of the three cytokines in THP-1 cells through different pathways. The primary study of Ebosin on anti-inflammation mechanism was promoted developing the new drugs treating rheumatic arthritis.

Cell transplantation has great potentials in repairing damaged tissue.If we want to use the cell transplants to treat diseases that respond poorly to the conventional treatment,or provide better treatments,in vivo dynamic tracking is particularly important.The application of superparamagnetic iron oxide (SPIO) improves a common inconvenience of the current invasive tests including immunohistochemical study or transmission electron microscopy (TEM) study and so on.Researchers has established a variety of preparation methods of the particles,groped the optimal condition of cell marking.SPIO were proved to be feasible and superior in cell tracking in vivo through animal experiments.The results provide the reliable means of using SPIO to track cell in clinical treatments.This review gives a summary of the related study.

Objective To explore clinical significance of subtemporal decompression in traumatic total anterior circulation infarcts(TTACI).Methods 24 TTACI cases accepted subtemporal decompression were analyzed including CT scan feature, pre operative observation to temporal superficial artery, operative cranial pressure classification and blood circulation in cortical small artery.Results Clinical symptom compared between before and after operation: good 4 cases, unchanged 14 cases, dead 6 cases. CT scan showed infarct areas became smaller in 4 cases, unchanged in 9 cases, larger in 2 cases three months after operation.Conclusion Subtemporal decompression cannot reduce the areas of infarcts and mortality, nor improve neurological function and promote quality of survivor.

As an important incentive for cardiovascular disease, cancer, diabetes and other chronic diseases, obesity after cardiovascular disease and cancer has been listed as the third largest threat to human health by World Health Organization. Recent research has shown that obesity is associated with colorectal cancer, esophageal cancer, kidney cancer, endometrial cancer, however, it has not been fully disclosed that the mechanism could lead to an increased risk of tumors. Leptin and adiponectin are a kind of hormone secreted by adipose tissue, which involve in the energy metabolism, and play an increasing significant role in the tumors' affecting factors.

Functioning gonadotroph adenomas (FGA) are pituitary tumors secreting biologically active gonadotropins.Because of its low incidence,it can be diagnosed only in evident clinical manifestations,and clinicians are often not able to make right diagnosis.The published literature includes only small case series or individual case reports.In this review,we will focus on the main presenting manifestations,the reported management options,and the long-term outcome of the FGA.

Objective To investigate the effect of rivaroxaban on prevention from deep venous thrombosis after hip replacement surgery .Methods 80 patients with lower limb parallel arthroplasty were randomly divided into observation group and control group from January 2014 to January 2015.40 cases in each group.Control group was given aspirin treatment, observation group was given rivaroxaban treatment, indicators changes were followed up and recorded.Results PT, APTT values of observation group one week after treatment were (35.79 ±2.16),(15.84 ±2.11) s, which were better than control group (45.64 ±2.12),(18.72 ±2.02) s (P<0.05).TT, D-dimer of observation group(13.48 ±2.10)s,(2.34 ±0.33)g/L after a week were better,than control group (16.38 ±1.79)s, (1.42 ±0.21)g/L (P<0.05) respectively.Conclusion Effect of rivaroxaban in prevent deep venous thrombosis after hip replacement surgery is exact without obvious adverses reaction, it is worthy of further research and application.
