Objective To detect the expression of IL-6 in peripheral blood of patients with gastric cancer,as well as the expressions of IL-6,IL-6 receptor(IL-6R) and proliferating cell nuclear antigen(PCNA) in the neoplastic tissue in order to investigate the clinical significance of such expressions in looking for a convenient and effective way for the diagnosis and therapy of gastric cancer.Methods Enzyme-linked immunosorbent assay(ELISA) was employed for the parallel semi-determination of IL-6 levels in the peripheral blood of 30 patients with gastric cancer,as well as the levels of IL-6 and IL-6R in the neoplastic and adjacent tissues.The expression of PCNA in the neoplastic tissues was determined with immuno-histochemistry technique.Moreover,the correlation was comprehensively analyzed among IL-6,IL-6R,PCNA and the clinicopathologic findings of gastric cancers.Results The IL-6 levels in both peripheral blood and neoplastic tissues of 30 patients were significantly higher than those of the normal controls.The IL-6 levels in peripheral blood decreased significantly after operation;the IL-6 and IL-6R levels in cancer tissues were significantly higher than those in their adjacent tissues with a positive correlation between IL-6 and IL-6R levels.The expressions of IL-6,IL-6R and PCNA in both peripheral blood and neoplastic tissues of patients were positively related to the clinical manifestation of gastric cancer,including the differentiation degree of cancer cells,tumor size,infiltration extent and the metastasis of cancer cells.Conclusions IL-6,IL-6R and PCNA are the important factors which affect the degree of malignancy of the gastric cancer concerned,and they also,reflect the possibility of infiltration and metastasis of cancer cells.The IL-6 level in peripheral blood and the levels of IL-6,IL-6R and PCNA in tumor tissues of patients with gastric cancer are obviously high.The expression levels of all these factors are correlated with the clinicopathologic findings of gastric cancer.An adequate determination of IL-6 and PCNA is of benefit to the diagnosis and treatment of gastric cancer,and to the judgment of the course and prognosis of gastric cancer.

Objective To investigate the clinical and pathological prognostic factors in patients with carcinoma of ampulla of Vater treated by pancreatoduodenectomy.Methods The clinical and pathological factors of patients with carcinoma of ampulla of Vater who were operated from February 1994 to February 2009 at the Urumqi General Hospital of Lanzhou Military Region were retrospectively analyzed.The survival curves of these patients were also analyzed.Results The post-operative 1-,3-,5-year survival rates were 90％,63％,55％ respectively.The diameter of the majority of tumor (58.3％) was less than 2.0 cm.Of all the patients with carcinoma of ampulla of Vater,48.7％ were in T1 stage,41.7％ had high grade differentiation,73.0％ had no lymphatic metastasis.Univariate analysis showed that gender,age,tumor diameter,biopsy or not,the type of operation,the value of pre-operative serum bilirubin and the value of serum CA19-9 were not related to survival.The gross type of tumor (P =0.018),histological type (P =0.000),grade of differentiation (P =0.003),depth of infiltration (P =0.003),lymphatic metastasis (P =0.014) and TNM stage (P =0.031) were significant impact factors of survival.Multivariate analysis showed histological type and depth of infiltration were independent prognostic factors of surviva1 (P =0.002,P =0.005).Conclusion Grossly ulcerated carcinoma,mucinous adenocarcinoma on histology,low degree of differentiation,T2/T3 stage,lymphatic metastasis and clinical stage of Ⅱb were all significantly associated with poor prognosis in patients with carcinoma of ampulla of Vater treated by pancreatoduodenectomy.Histological type and the depth of infiltration were the most important risk factors of survival.

Background The pathogenesis of myopia is currently unclear. Studies showed that retinoic acid regulates the development of myopia. Whether IRBP, a retinoid transport proteins, participates in the development of myopia or not is unknown. Objective The aim of this study was to investigate the expression of interphotoreceptor retinoid-binding protein (IRBP) in the retina of guinea pig with lens-induced myopia and study the relationship between IRBP expression and experimental myopia. Methods Fifty guinea pigs were randomized into the normal controls(n=10) ,defocus Ⅰ group (n=20) and defocus Ⅱ group (n=20). Guinea pigs in the defocus Ⅰ groups wore -10. 00 D lenses on the right eyes for 14 days and the defocus Ⅱ group for 28 days. The left eyes of both defocus groups did not wear any lens served as self-control. The refraction diopter and axial length were measured before and after wearing lenses. The protein expression of IRBP in the retina was detected by immunohistochemisty and Western blot. RT-PCR was used to observe the level of IRBP mRNA in the retina. Result Compared with the control eyes,the right eyes in the defocus Ⅰ and Ⅱ groups developed to ( -5. 53±1.93) D and (-8.69±2.46) D, and the ocular axial length elongated to (0. 31±0. 15 ) mm and (0.41 ±0. 13 ) mm, showing statistically significant differences between them ( group Ⅰ: t= 12. 57,29.63 ,P＜0.05 ;group Ⅱ :t= 15.82,44.35 ,P＜0.05 ) ,and the degree of myopia was lower and axial length was shorter in group Ⅰ than the eyes of group Ⅱ ( P＜0.05 ). There was no statistically significant differences found between the left eyes of defocus group Ⅰ and defocus group Ⅱ or eyes of the control group in diopter and axial length (P＞0.05). Immunochemistry revealed that the mean gray value of IRBP protein expression was 165.62t4. 93 and 171.00±4. 25 in defocus Ⅰ group and defocus Ⅱ group and was significantly higher than that of the self-control eyes and the normal control group ( 156. 31±4.00,155.26 ±3.49 and 158.61 ±4. 58 ) ( P＜0.05 ). Western blot demonstrated that the expressios of IRBP protein were down-regulated and RT-PCR showed the IRBP mRNA level of IRBP was significantly lower in defocusIgroup and defocusⅡgroup,compared with the self-control eyes and the normal control group (P＜0. 05). Conclusion Expression of IRBP in guinea pig may play a role in lens-induced myopia.

The personnel training is one of the core tasks of clinical Chinese pharmacy.Since the professional training of clinical Chinese pharmacy has started relatively late in China,the teaching contents and curriculum still need further improvements.This paper is aiming at analyzing the post tasks of personnel of clinical Chinese pharmacy,defining the knowledge structure of them,and learning from the characteristics of clinical Chinese pharmacy teaching systems of the foreign and domestic universities.On such basis,the paper proposes the ideas about constructing the curriculum system of clinical Chinese pharmacy,to provide a reference for the higher educational personnel training of clinical Chinese pharmacy.

Professor XIE Qiang's Tihu Guanding needling method, a kind of acupuncture method which takes acupoints of the Conception Vessel as the primary and acupoints of the Governor Vessel as the secondary. Acupoints Lianquan (CV 23), Tiantu (CV 22), Qihai (CV 6), Zhongwan (CV 12), Baihui (GV 20) and Dazhui (GV 14) are adopted as the basic ones. Other points can be added according to various symptoms, for instance, Yingxiang (LI 20) and Yintang (GV 29) for rhinopathy, Tinggong (SI 19) and Yifeng (TE 17) for otopathy, Yan'an (Professor XIE's experience) and Shanglianquan (EX-HN 21) for pharyngopathy and Kaiyin 1 (Professor XIE's experience) and Kaiyin 2 (Professor XIE's experience) for laryngopathy. During the needle retention, rotation manipulation should be done every 5 min at Lianquan (CV 23). And the patient should be told to put the tip of one's tongue at the the palate as well as to do deep breathing to communicate the Conception Vessel and the Governor Vessel. Moxibustion is adopted at Yongquan (KI 1) to induce the up floating fire to mingmen (where the primary yang is stored). The therapeutic effect on treatment of persistent otorhinolaryngologic diseases with the above mentioned method is approve to be good.

The quail model of hyperuricemia combined with abdominal obesity was induced by high purine diet.Body weight in model group showed no change.Serum uric acid level in model group was increased significantly on 7,14,21,and 28 d( P＜0.05 or P＜0.01 ).Abdominal fat index in model group increased significantly on 28d.On 7 d and 28 d,serum free fatty acid level was increased significantly.Acetyl-CoA carboxylase( ACC ) protein expression in the liver of model quail was increased as shown by ELISA and immunohistochemisty ( P＜0.05 or P＜0.01 ),suggesting that the alteration of ACC expression contributes to the pathogenesis of hyperuricemia combined with abdominal obesity.
