Anxiety disorder is one of the most common mental disorders and seriously impairs the physical and mental health of patients. Due to the efficacy of acupuncture for tranquilization, acupuncture displays its unique advantage on the treatment of anxiety disorder, but the relevant biological mechanism has not been elaborated. The modern medicine study has proved that the heart and brain have their own independent natriuretic peptide (NP) system. The dysfunction of ANP and its receptor are closely related to the occurrence of anxiety disorder. The ANP acts on anti-anxiety. Hence, focusing on the three aspects, named the anti-anxiety effect of acupuncture based on its tranquilizing effect, the anti-anxiety effect of ANP and the positive regulation of acupuncture on NP, the mechanism on ANP and its receptor was explored in anti-anxiety with acupuncture based on tranquilizing effect, and the idea was put forward on that the anti-anxiety effect of acupuncture was possibly based on its action of tranquilization through regulating the ANP and its receptor. As a result, it is expected to provide the theoretic support for the mechanism study on anti-anxiety with acupuncture based on its tranquilizing effect.

Data analysis poses a significant challenge to the large-scale proteomics studies. Based on the structured and controlled vocabularies-Gene Ontology (GO), and the GO annotation from related databases, a strategy composed of several programs and local databases is developed to identify the functional distribution and the significantly enriched functional categories of the proteomic expression profile. It would be helpful for understanding the overall functions of these identified proteins and supply the fundamental information for further bioinformatics exploration. This strategy has been successfully used in the Human Fetal Liver (HFL) proteomic research, which is available online at http://www.hupo.org.cn/GOfact/.

Surgical resection is considered to be the most effective therapy for hilar cholangiocarcinoma.Inadequate excision range is the main reason for recurrence after surgery.Extended radical resection provides better long-term survival,however,it may also increase the risk of liver failure because of the extensive hepatic resection.In present study,we showed a new operation which could excise enough length of bile ducts and avoid large volume hepatic tissue resection.The excision extension includes:segment Ⅰ,Ⅳb and partial Ⅳ,left,right and furcation of hepatic duct,extrahepatic ducts,skeletonization of hilar vessels,and dissection of at least second station lymph nodes.As the tissue resected resembles a dumbbell,this surgical technique is named dumbbell type radical resection.The operative indications include:(1) hilar cholangiocarcinoma,Bithmuth Ⅱ and Bithmuth Ⅲ with tumor limited in left or right hepatic ducts ; (2) Without portal invasion; (3) Without third station lymph node metastasis; (4) Without liver or distant organ metastasis.Twenty-three patients had undergone this operation sucessfully.Most patients have high total bilirubin levels (more than 300 μmol/L) and have not received percutaneous transhepatic cholangial drainage or biliary drainage.The average operation time was 355 minutes,and average volume of blood loss during operation was 350 ml.The total survival rate was 65.2%.One-year tumour free survival rate was 95.7% (22/23),and three-year tumor free survival rate was 7/15.The results indicated that dumbbell type radical resection was feasible for hilar cholangiocarcinoam of Bismuth Ⅱ and Bismuth Ⅲ with tumor limited in left or right hepatic ducts.

Objective To study the expression of aquaporin-4 (AQP-4) in core and marginal region of the contusion brain tissues from patients with severe traffic brain injuries. Methods Thirty patients with severe traffic brain injuries (frontal-temporal brain contusion) admitted into our department from January 2007 to July 2009 were enrolled in the study and divided into three groups according to the period from injury to operation, ie, 0-4 hours (Group A), 5-8 hours (Group B) and 9-12 hours (Group C). The tissue was collected from core and marginal regions of brain contusion in each group. Ten parts of normal brain tissues obtained from the cerebellum to gain good exposure of CPA region tumors were used as control. The expression of AQP-4 in the normal brain tissues and in the tissues from core and marginal region of brain contusion, with GAPDH used as a control. Results The expression of AQP-4 in the marginal region was distinctly higher than that in normal tissues and in the tissues from core region. The AQP-4 expression in the tissues of the core region was lower than that in normal tissues. Conclusions AQP-4 is highly expressed in the tissues from the marginal region early after injury in a time-dependent fashion. Low expression level of AQP-4 in the core region is possibly correlated with early damage of blood brain barrier and peripheral structures.

Printed-circuit-board ion trap (PCBIT) is a novel ion trap mass analyzer,which is capable of optimizing its internal electric field distributions by adjusting the radio frequency (RF) voltage-divided ratio to improve its analytical performance.This work introduced odd electric field components into the trapping volume to achieve unidirectional ion ejection by applying asymmetric RF voltages to x electrode pairs of PCBIT.In this case,the center of ion vibration was displaced away from the geometrical center of PCBIT and ions were ejected predominantly through one of x electrode pairs.The relationship between asymmetric voltage-divided ratio (AV) and internal electric field distributions was investigated by simulation software SIMION and AXSIM.At the same time,the ion trajectories and simulated mass spectrum peaks were calculated.The results showed that,for ions with m/z 609 Th,a mass resolution over 2500 and an ion unidirectional ejection efficiency of over 90% were achieved in PCBIT with AV=20% at an appropriate frequency of AC.Using this method,ion unidirectional ejection efficiency of PCBIT can be significantly improved while maintaining a high mass resolution,which makes the PCBIT more suitable for developing miniaturized mass spectrometer.
