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.

Compared with patients with high-middle rectal cancer,local recurrent rate of low rectal cancer in patients is worse.The poor outcome of low rectal cancer is due to the unique anatomical features of the low rectum and the lack of clearly defined anatomical excision planes.Therefore,how to use the appropriate imaging methods,evaluate accurately preoperative cancer staging,plan feasible surgical plane and select the appropriate surgical approach,these will be very important for radical resection of rectal cancer.Therefore,the quality of life and long-term survival of the patients will be improved.

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.

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.

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.

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.

Janus kinase-signal transduction and transcription activator (JAK-STAT), mitogen- activated protein kinase (MAPK) and nuclear factor ?B (NF-?B) are three important cellular signalling pathways, which play pivotal roles in regulation of cellular physiologic as well as pathophysiologic functions. Based on the elucidation of the research progress of three signalling cascades, respectively, the current review focuses on the cross-talk of these signalling transduction, and the up-to-date details are also presented on their regulation in inflammatory response.

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.

OBJECTIVE:To discuss the status quo and the development strategy of the study of the processing of Chinese herbal medicine.METHODS:The physical-chemical property,the technology transfer and the qualitation and quantitation reported in the literature about the processing of Chinese herbal medicine were analyzed and summarized.The status quo and the current methods for the study of processing of Chinese herbal medicine were expounded and its development strategy was put forward in view of the role and importance of the processing study.RESULTS & CONCLUSION:To develop the study on the processing of Chinese herbal medicine,it is essential to strengthen literature research and summarizing of experiences as well as the combination of processing synergy with clinic practice,attach great importance to the guiding effect of traditional Chinese medicine theory on the study of physical-chemical study in the processing of Chinese herbal medicine,and strengthen study on the key issues including the processing technology of Chinese herbal medicine and the quality control of decoction pieces.

Objective To investigate the clinical manifestations, histopathological patterns and causes of misdiagnosis of primary malignant tumor in small intestine (PMTSI). Methods The clinical data of 90 cases of PMTSI confirmed by pathology admitted from 1981 to 2002 in our hospital were retrospectively analyzed. Results The main pathological patterns of PMTSI were adenocarcinoma, leiomyosarcoma, lymphoma and malignant neurilemmoma. The common clinical manifestations were abdominal pain, anemia and hemorrhage, jaundice, weight loss and intestinal obstructions. Preoperative diagnosis rate was 22.2%(20/90). It was easily misdiagnosed as other digestive tract diseases and pelvic disorders. Preoperative misdiagnosis rate was 77.8%. Conclusions The main pathological patterns of PMTSI are adenocarcinoma, leiomyosarcoma, lymphoma and malignant neurilemmoma.Its clinical manifestations and diagnostic examination methods are not good enough, which usually leads to misdiagnosis ,so attention must be paid.
