Differentiating bipolar disorder (BD) from unipolar depression (UD) is an important clinical challenge.Review the development of Magnetic Resonance Imaging ( MRI) in distinguishing the BD and UD, identifying objective markers of BD, to optimize clinical decision making.Database including PubMed,Wan Fang,CNKI and so on.The key words were usedunipolar depressionormajor depressive depression,bipolar depression,MRI,modeland so on.A little neuroimaging studies to date have directly compared UD and BD depressions.Most results from these studies suggest more heavy neural circuit abnormalities in BD than UD depression,involved in different brain regions.Predictive models based on neu-roimaging characteristics of BD and UD obtain a higher accuracy and can help differentiate BD from UD.This review serves as a call to highlight the need for more neuroimaging studies to compare individuals with BD depression with individuals with UD depression directly.Using neuroimaging results as objective biological i-dentification markers is a feasible research field.

Transcutaneous immunization (TCI) is a novel immunotherapy approach that induces systemic immune responses via topical application of antigens and adjuvants onto the skin.It is a safe and effective method,and is expected to serve as an attractive alternative to traditional vaccination.TCI induces immune responses in different directions,but the exact mechanism of skin immune tolerance is still unclear.Most studies on TCI are based on animal models.However,there are structural differences between animal skin and human skin,so more researches are needed to achieve the translation of TCI from bench to bedside.Not all vaccines are suitable for cutaneous inoculation,so vaccines for TCI should be evaluated for their safety and efficacy.Various reformed vaccine delivery systems are needed to be further explored in related diseases.

The principle of R0 resection for colorectal cancer(CRC)has been widely accepted based on the preoperative imaging evaluation.The surgeons should scientifically and strictly assess resectability of tumors and furthest reduce tumor residuals.Patients with initial unresectable CRC will give priority to conversion therapy and then undergo R0 resection if converting into resectable tumors.Palliative operation for the patients who cannot receive R0 resection according to the clinical assessment should strictly follow surgical indications and achieve wellplanned and clear surgical purposes.There is no evidence that the palliative operation or cytoreductive surgery benefits to survival of patients,and decreasing complications and improving quality of life through minimum wound are the basic principles.

Colorectal cancer is one of the most common malignancies in human.Early diagnosis is the key points in improving the prognosis of patients with colorectal cancer.The implementation of standardized operation and comprehensive treatment for advanced and late stage cancer can improve the outcome.Based on the pattern of lymph node metastasis and the concept of complete mesocolic excision,the operation of colonic cancer has entered the era of normalization and standardization.The surgical procedure of rectal cancer (especially low rectal cancer) should be individualized based on the gold standard of total mesorectal excision (TME).For hepatic metastasis of colorectal cancer,hepatectomy is currently the standard and the only potentially curative treatment method.Therefore,how to evaluate the resectability of hepatic metastasis of colorectal cancer is particularly important.Surgeons are the most important participants in the diagnosis and treatment of colorectal cancer,and standardized diagnosis and treatment is the key to improve the prognosis of patients.

ObjectiveTo observe the effects of high mobility group box-1 protein ( HMGB1 ) on function of murine spleen IL-10-producing dendritic cells (DCs) subset CD11clowCD45RBhighDCs.MethodsSplenic CD11clowCD45RBhighDCs and CD4 +T cells in Balb/c mice were purified by magnetic beads sorting.CD11clowCD45RBhighDCs were treated with various doses of HMGB1 (0,20,100,500ng/ml).Flow cytometry was used to determine expressions of CD11clowCD45RBhighDC surface molecules including CD40,CD80,CD86,Ⅰ-a/e and Toll-like receptor (TLR) 4.IL-10 level in CD11clow CD45RBhighDC culture supernatants was determined by ELISA method.The CD4+ T cells were divided into four groups: control group (without only treatment),untreated group (HMGB1-untreated CD11clow CD45RBhigh DCs plus CD4+T cells),high-dose HMGB1-treated group (500 ng/ml HMGB1-treated CD11clowCD45RBhigh DCs plus CD4 +T cells),high-dose HMGB1-treated + antibody 1 group (500 ng/ml HMGB1-treated CD11clowCD45RBhigh DCs plus IL-10 antibody and CD4+T cells),high-dose HMGB1-treated + antibody 2 group (500 ng/ml HMGB1-treated CD11clow CD45RBhigh DCs plus homotype IL-10 antibody and CD4 +T cells).IL-4 as well as interferon( IFN-γ) contents in CD4 + T cell culture supernatants were determined by flow cytometry.ResultsHMGB1 could markedly enhance the expressions of CD40,CD86 and TLR4 on CD11clowCD45RBhigh DC surface as well as level of IL-10 secreted by CD11clow CD45RBhigh DCs as compared with the non-HMGB1 treatment.Meantime,the secretion of IL-10 was HMGB1 concentration dependent.IFN-γ level in high-dose HMGB1-treated group was (279 ± 17) pg/ml,which was markedly lower than that in the untreated group [ (963 ± 11 ) pg/ml,P ＜ 0.05 \ ].IL-4 level in high-dose HMGB1-treated group was (372 ± 14) pg/ml,which was significantly higher than that in the untreated group [ (213 ± 10) pg/ml,P ＜0.05) \].ConclusionsHMGB1 promotes IL-10 production in CD11clowCD45RBhighDCs,induces the differentiation of CD4 +T cells to Th2 cells and downregulates the immune response via activating CD11clowCD45RBhigh DCs.

Objective To compare the treament to adhesion ileus between laparoscopic surgery and traditional surgery.Methods 59 cases of patients with adhesion ileus were selected.32 patients were given laparoscopic adhesion ileus loose solution method.And the other 32 patients were given traditional surgery.Results The operation time(t =12.135,P =0.002),peristalsis recovery time (t =9.053,P =0.001),postoperative infection rate (x2 =8.346,P =0.004),obstruction again (x2 =4.863,P =0.026) and hospital stays (t =4.724,P =0.028) in laparoscopic surgery group was significantly better.The differences between both groups were statistically significant (P ＜0.05).Conclusion Compared with the traditional open surgery,laparoscopic adhesion ileus loose solution with surgical trauma is small.Operation time and the postoperative recovery time is short,It can be used as the main treatment of adhesion ileus.

Translation is a process not only concerning on the language transformation, but also concerning on the cultural communications. However, due to the diversity between cultures, translation loss is a stumbling block which has to be coped with, or a necessary process called translation compensation. This paper, employing the method of text analysis, attempts to compare two English versions ofHuangdi-Neijing by Veith and Li-Zhaoguo as study cases to discuss the translation compensation strategies from the perspective of Bassnett’s cultural translation theory, thus achieving the optimal translation effect.

Dioxin has been included in the list of monitoring objects in food part of the global environment monitoring program as a new environmental pollutant by World Health Organization. In this paper,the toxicity,the source of dioxin and its impact on human health and prevention and control measures are introduced.

To investigate the effect of thiopental sodium on the release of glutamate and gamma-aminobutyric acid (GABA) from synaptosomes in the prefrontal cortex, synaptosomes were made, the spontaneous release and the evoked release by 30 mmol/L KCl or 20 micromol/L veratridine of glutamate and GABA were performed under various concentrations of thiopental sodium (10-300 micromol/L), glutamate and GABA concentrations were determined by reversed-phase high-performance liquid chromatography. Our results showed that spontaneous release and evoked release of glutamate were significantly inhibited by 30 micromol/L, 100 micromol/L and 300 micromol/L thiopental sodium, IC50 of thiopental sodium was 25.8 +/- 2.3 micromol/L for the spontaneous release, 23.4 +/- 2.4 micromol/L for KCl-evoked release, and 24.3 +/- 1.8 micromol/L for veratridine-evoked release. But GABA spontaneous release and evoked release were unaffected. The study showed that thiopental sodium with clinically related concentrations could inhibit the release of glutamate, but had no effect on the release of GABA from rats prefrontal cortical synaptosomes.
