[Objective] To explore part of mechanism of Qizhu Jianzhong Decoction treating gastric ulcer and spleen Yang deficiency, impersonally state the scientific connotation of the decoction. [Method] Randomly divide 60 SD rats into normal/ blank control group(Ⅰ), model group(Ⅱ), sucralfate group(Ⅲ), large-dosage group(Ⅳ), middle-dosage group(Ⅴ) and small-dosage group(Ⅵ) of Qizhu Jianzhong Decoction. Except for the group Ⅰ, others are made into rats model of spleen yang deficiency and gastric ulcer with abnormal diet, fatigue, cold and bitter purgation, and cold water stimulant. After being administered medicines, measure their IL-6 and GAS level, and observe the pathological changes of gastric mucosa under microscope. [Result] Compared with group Ⅰ, in the model group, the IL-6 rose, GAS decreased; compared with the model group, other groups of Ⅲ, Ⅳ and Ⅴ all markedly decreased rats serum Ⅱ-6 level and increased GAS level, with obvious difference(P0.05). Under microscope, the gastric mucosa injury degree was less in groups Ⅲ, Ⅳ and Ⅴ than group Ⅱ; and it was similar between group Ⅵ and group Ⅱ. [Conclusion] Groups Ⅳ and Ⅴ have marked cure effect on spleen yang deficiency and gastric ulcer, and group Ⅵ has no obvious cure effect.

Objective To design a new presigmoid translabyrinthine keyhole approach assisted by Stryker neuro-navigation system according to the keyhole idea,and observe microscopic anatomy structures, which could be.regarded as the bases of this approach in clinical application.Methods Navigation data were established on 8 cadaveric heads fixed by formalin and perfused intracranial vessels with colored silicone. A 7-cm postauricular C-shaped skin incision as we reported was performed.After elevating the skin flap and musculofascial flap,a 3.5 cm?3.0 cm bone window was made.On skeletonizing the sigmoid sinus,bony lab- yrinth and the canal for facial nerve,the presigmoid retrolabyrinthine,partial labyrinthectomy with petrous api- cectomy,translabyrinthine keyhole approaches were simulated in turn.The length of important structures ex- posed and the angle of vision were measured step by step, and the anatomic structures were observed.Re- suits The approach-correlated bone could precisely be drilled with the aid of neuro-navigation,which could avoid the bewilder in drilling process.The angles of visual field,the length of clivus andⅦcranial nerve were significantly increased after partial labyrinthectomy with petrous apicectomy or all labyrinth removal,but there were no significant difference between partial and all labyrinth removal.The retrolabyrinthine keyhole approach spares hearing and facial function but provided for limited window of petroclival region exposure.The partial labyrinthectomy with petrous apicectomy keyhole approach provided wider exposure to petroclival region,cere- bellopontine angle,prepontine region and posterior cavernous sinus;an area between theⅢ-XI cranial nerves was easily visible with an excellent chance of hearing and facial nerve preservation.The translabyrin- thine keyhole approach,producing more morbidity,provided for greater versatility in treating lesions,added little exposure of petroclival region.Conclusion The presigmoid translabyrinthine keyhole approach,which could provide excellent exposure of the petroclival region,was feasible to be performed in our study.The ap- proach-correlated bone could be precisely removed assisted by neuro-navigation system.The exposure was oh- viously increased hy partial labyrinthectomy with petrous apicectomy or all labyrinthine removal,the former provided an excellent chancre of hearing and facial nerve preservation.

Standardization of traditional Chinese medicine(TCM)term translation is the focus of TCM translation studies. Based on the Skopos theory and our interviews to 6 internationals, this paper aims to explore the purposes and principles of TCM term translation from the perspective of the client, the translator and the addressee. Finally, four fundamental principles of TCM term translation are summarized in order to provide references for the standardization of TCM term translation.

Objective This paper addresses the standardization of traditional Chinese medicine(TCM) nomenclature translation and put forward suggestions through a comparative study on English translations of TCM terms for liver and gallbladder diseases.Method With the principle of standardization, the principle of correspondence, the principle of readability and the principle of nationalism as the possible criteria, translations of 8 TCM terms available in 7 publications at home and abroad are compared and analyzed.Results 5 of the 8 terms have at least two English versions. The principle of standardization and the principle of readability are violated more frequently than the other two.Conclusion The standardization of TCM nomenclature is progressing steadily.However, efforts are still necessary for translators to improve English language proficiency. The principle of standardization and the principle of readability need to be further enhanced.

Objective To assess the intensity of the pain and its negative impact on patients with protrusion of lumbar intervertebral disc (PLID) through using a case-control study. Methods 94 patients with PLID and 398 control individuals were enrolled in this study. The pains were assessed using McGill questionnaire. Results The sensory pain score(5.22?2.22), affective pain score (2.68?0.81)and VAS score (7.79?1.42)in the patient group were significantly higher than those in the control group (P

Objective To investigate angiographic manifestations and interventional treatment of renal arteriovenous fistulas. Methods Renal arterial angiographies were performed in 20 patients from multiple hospitals.These patients suffered from repeatedly intermittent hematuria,but ultrasound,KUB,IVU,CT and endoscopy could not contribute to the diagnosis.The angiographic manifestations and treating procedure were analyzed. Results All the 20 cases were diagnosed as renal arteriovenous fistula by means of angiography.According to the image manifestations,these cases were classified into three types:(1)deformed branches and shunt in 11 cases;(2)high discharge shunt without deformed banches in 4;(3)concealed shunt showed by superselective segmental artery angiography but negative by renal artery angiography in 5.All fistulas of the 20 cases were successfully embolized with different materials including gelfoam,sodium morrhuate,ethanol,PVA,TH-glue,coils,etc. Conclusions Superselective renal angiography and embolization are the most important and effective tools for diagnosis and treatment of renal arteriovenous fistula.

Objective To study the effect of TBTCl on the immunity of mice. Methods The mice were randomly divided into 5 groups, namely groups of negative control, low dose (0.8 mg/kg), moderate dose (4 mg/kg), high dose (20 mg/kg) and positive control. Gavage was employed to administrate TBTCl to mice for two consecutive weeks, the number of T-lymphocyte in blood and invert ability of T-lymphocytes in spleen, hemolysin in serum, clearance exponent and viscera quotiety were determined to study the effect of TBTCl on immunity of rats. Results Compared with the control, no significantly increased T-lymphocytes were seen in low dose group, in moderate dose group the number of T-lmphocyte and the production of hemolysin increased, no obvious changes in the clearance exponent and viscera quotiety were seen. In high dose group, a significantly decreased T-lymphocytes, the clearance exponent and viscera quotiety were observed. Conclusion Low level TBTCl exposure may stimulate the immune system of mice, high exposed to TBTCl may intensively inhibit the immune system.

Aim To investigate the effect of Trichostatin A(T SA)on histone deacetylase (HDAC1) and P21 WAF1/CIP1,cyclin dependent ki nase inhibitor,in NB4 cells for exploring the underlying mechanism of TSA in an ti-leukemia.Methods The total proteins and P21 WAF1/CIP1 mRN A were extracted from acute promyelocytic leukemia NB4 cells treated with or wit hout TSA of different concentrations at different time points,Western blot anal ysis was performed to determine the level of HDAC1 and P21 WAF1/CIP1 protei n,respectively,and RT-PCR was performed to detect the level of P21 WAF1/CI P1 mRNA.Results (1)The level of HDAC1 was obviously inhibited by TSA,and had decreased at 4 hours at IC 50 and lasted for 48 h. The inhibi tion of HDAC1 was significant at the TSA concentration of 37.5 nmol?L -1 , but there was no difference between 75~300 nmol?L -1.(2)The levels of P21 WAF1/CIP1 mRNA and protein were up-regulated by TSA in dose-and ti me-dependent manner,and mRNA increased in 8 h,but the P21 WAF1/CIP1 prot ein was detected at 12 hours and lasted for 48 hours.Conclusion TSA could inhibit the level of HDAC1 and enhance the expression of P21 WAF1/CIP1 protein and mRNA,and the results suggest that inhibiting HDAC1 and increasin g P21 WAF1/CIP1 may be one of the possible mechanisms of anti-leukemia by TSA.

Aim To investigate the effect of selective cyclooxygenase-2 inhibitor, NS-398, on cell apoptosis in leukemia cell line K562 cells and its underlying mechanism. Methods Apoptotic cell percentage was examined by flow cytometry(FCM). The protein expression of Bcl-2 and Caspase-3 was detected by Western blot, and the activity of Caspase-3 was checked by FCM. Results NS-398 induced the cell apoptosis in K562 cells in a dose-dependent manner. After NS-398 treatment, the expression of Bcl-2 protein was downregulated, whereas the expression of Caspase-3 protein was upregulated. Moreover,the activity of Caspase-3 was increased in a dose-dependent way after NS-398 treatment. Conclusion Selective cyclooxygenase-2 inhibitor,NS-398,significantly induced apoptosis in K562 cells. The underlying mechanism might be related to the downregulation of Bcl-2 and the activation of Caspase-3.
