OBJECTIVE: The research is aimed at investigating the developing rule and the relationship between syndrome differentiation in traditional Chinese medicine (TCM) and clinical factors of gastric cancer, so that it can be helpful to the clinical work and indicating the prognosis. METHODS: We collected the medical records and the information of four diagnostic methods of 325 cases of gastric cancer sufferers in the way of clinical epidemiological survey, and divided them into 6 syndromes including dysfunction of spleen, disharmony of liver and stomach, blood stagnation in stomach, yin deficiency of stomach, phlegm dampness stagnation and deficiency of both qi and blood. Then we used univariate analysis of variance, rank sum test and chi square test to analyse the relationship between syndrome differentiation and clinical-related factors such as age, gender, Karnofsky score and clinical stage, etc. RESULTS: The syndrome of dysfunction of spleen plays the primary role in the disease. Disharmony of liver and stomach always happens in early stage of stomach cancer, usually more often in radical operation cases and less in metastasis ones. It also has a high proportion in female. Phlegm dampness stagnation and blood stagnation in stomach usually can be seen in middle or advanced stage of the disease, which have lower Karnofsky score. Deficiency of both qi and blood is the syndrome of stomach cancer in advanced stage, which results in lower living quality, and with high rate of relapse and metastasis. Syndrome of yin deficiency of stomach has lower proportion in stomach cancer cases, and the clinical-related factors have low influence on it. CONCLUSION: Syndrome in TCM of gastric cancer is relevant to some clinical factors and varies in progress.

OBJECTIVE: The research is aimed at investigating the developing rule and the relationship between syndrome differentiation in traditional Chinese Medicine (TCM) and clinical factors of gastric cancer so as to guide clinical work and indicate prognosis. METHODS: We collected the medical records and the information of four diagnostic methods of 325 cases of gastric cancer sufferers in the way of clinical epidemiological survey, and divided them into 6 syndromes including dysfunction of spleen, disharmony of liver and stomach, blood stagnation in stomach, yin deficiency of stomach, phlegm dampness stagnation and deficiency of both qi and blood. Then we used logistic regression analysis to analyze the relationship between syndrome differentiation and clinical-related factors such as age, gender, Karnofsky score and clinical stage, etc. RESULTS: The syndrome spleen dysfunction is a dominant one among the syndromes of stomach cancer. Disharmony of liver and stomach always happens in early stage of stomach cancer and is frequently seen in women. Patients with syndrome of phlegm dampness stagnation or deficiency of both qi and blood have lower Karnofsky score and poorer living quality. Syndromes of blood stagnation in stomach and yin deficiency of stomach show no relationship with the clinical factors in this research. CONCLUSION: Syndrome differentiation in TCM of gastric cancer is related to some clinical factors to a certain extent.

Objective To compare the efficacy of three procedures,extracorporeal shock wave lithotripsy(ESWL),ureteroscopic lithotripsy(URL) combined with ESWL,and minimally invasive percutaneous nephrolithotomy(MPCNL),for the treatment of complicated upper ureteral calculi.Methods Two hundred and thirty-four cases of complicated upper ureteral calculi were treated in this hospital from December 2002 to December 2003,including 76 cases of ESWL,78 cases of combined use of URL and ESWL,and 80 cases of MPCNL.Results In the ESWL cases,the stone fragmentation rate on one session was 56.6%((43/76),) the stone-free rate one month after operation was 46.1%(35/76),the mean hospitalization expenditure was 912 yuan,and the incidence of postoperative complications was 15.8%(12/76).In the URL combined with ESWL cases,the stone fragmentation rate on one session was 100%(78/78),the stone-free rate one month after operation was 83.3%(65/78),the mean hospitalization expenditure was 7 720 yuan,and the incidence of postoperative complications was 15.4%(12/78).In the MPCNL cases,the stone fragmentation rate on one session was 100%(80/80),the stone-free rate one month after operation was 100%(80/80),the mean hospitalization expenditure was 10 253 yuan,and the incidence of postoperative complications was 13.8%(11/80).The operation time,intraoperative blood loss,length of hospital stay,stone-free rate one month after operation,and hospitalization expenditure were significantly greater in the MPCNL cases than in the ESWL cases and the URL combined with ESWL cases.The stone fragmentation rate on one session was not significantly different between the MPCNL cases and the URL combined with ESWL cases,and was significantly higher in the MPCNL cases and the URL combined with ESWL cases than in the ESWL cases.The incidence of postoperative complications was not significantly different among the three groups.Conclusions Minimally invasive percutaneous nephrolithotomy should be used as the first choice for complicated upper ureteral calculi.

Angiotensin Ⅱ(AngⅡ)can induce the expression of its precursor,angiotensinogen,in vascular smooth muscle cells(VSMC),which is related with increased activating protein-1(AP-1)binding to its cis-element located in the angiotensinogen gene promoter.In the present study,cycloheximide(CHX)was used as an inhibitor to interrupt c-Jun,the role of AP-1 in AngⅡ-induced its precursor gene activation was investigated by DNA-protein interaction and immunoblotting.The results showed that the level of c-Jun,the component of transcription factor AP-1,was significantly increased in the nucleus of VSMC after AngⅡ treatment.The majority of c-Jun was found in the nucleus but hardly detected in the cytoplasm by immunocytochemistry staining.Immunoprecipitation assays confirmed that AngⅡ could induce serine phosphorylation of c-Jun.EMSA results indicated that the level of phosphorylated of c-Jun had a positive correlation with AP-1 binding activity to cis-acting element of angiotensinogen gene and transcription activation of angiotensinogen.CHX inhibited AngⅡ-induced binding activity of AP-1 by reducing the phosphorylation of c-Jun,though it did not affect the expression of c-Jun.These findings suggest that the AP-1 phosphorylation induced by AngⅡ is one of the important mechanisms whereby AngⅡ regulates its precursor gene expression in feedback manner.It is found that CHX is an inhibitor to phosphorylation of c-Jun.

Objective To investigate whether octreotide,as somatostatin analogue,can enhance the sensitivity of the human lung adenocarcinoma cell line A549 to chemotherapeutic drugs.Methods Different concentration of octretide,cisplatin and 5-Fluorouracil (5-Fu) was respectively acted on the lung adenocarcinoma cell line A549.The absorbance value was tested by colorimetry through MTT method to evaluate the effect of octreotide,cisplatin,5-Fu or the three drugs combined respectively after 48 hours.Each drug concentration had six holes and it repeated three times.The effects of combination therapy was analysed with isobologram.Results It was proved that octreotide could inhibit the proliferation of A549 cells in a dose-dependent manner at the concentration range of 1.3 mg/L ～ 166.7 mg/L.The inhibition rate was dose-dependent which was higher when octreotide combined with cisplatin and 5-Fu than it alone.It has statistically significant difference (P ＜ 0.05 ).The effect plots of IC50 were located in the synergy areas of isobologram.Conclusion It can be concluded that octreotide could inhibit the proliferation of A549 cells in vitro.This inhibition enhances when octreotide is combined with cisplatin and 5-Fu.Octreotide can enhance the susceptibility of A549 cells to cisplatin and 5-Fu.

Objective To evaluate the effect of csomeprazole with different dosage and usage regimes on intragastric pH of healthy volunteers. Methods It was a randomized, open-label, three-way crossover study. Fifteen healthy volunteers received esomeprazole with 3 different dosages (20 mg or 40 mg once daily or 20 mg twice daily) with 5 days each. Twenty-four continuous ambulatory intragastric pH was recorded at day 5 of each regime. Results The mean time of intragastric pH above 4 was higher in regime of 20 mg twice daily [(21.16 ±2.45) hours ] than that in regimes of 20 mg once daily [(18. 70±4.19) hours] and 40 mg once daily [(19.27±2.68 ) hours] (P<0.05). The percentages of the sleeping and active period that pH remained above 3,4,5 were significantly higher in regime of 20 mg twice daily(day time:95.0%±7.5% ,92.0%±10.6% ,86.7% ± 14.5% ;night time:93.2%± 13.1% ,87.8%±20.3% ,78.6%±28. 9 % )compared with regimes of 40 mg once daily(day time:87.9%±9.5% ,83.5%±11.7%,75.6%±15.50%, night time:75. 7%±20. 8%,66. 9%±23. 8%,53. 3%±30. 3%) and 20 mg once daily(day time: 85.1 % ± 16.3 %, 81.1 %± 18. 1%, 71.5 % ± 20.3 % ; night time: 72.9 % ± 30.5 %,67.2 % ± 31.9 %, 55.7 % ± 31.8 % ) (P< 0.05 ). Esomeprazole maintained intragastric pH above these pH thresholds for a similar propotion of sleeping and active periods with 40 mg once daily and 20 mg once daily.Conclusions Esomeprazole has strong inhibitory effect on intragastric acid. The regime of 20 mg twice daily is superior to 40 mg once daily and 20 mg once daily in both day and night time acid inhibition.There is no difference between esomeprazole 40 mg once daily and 20 mg once daily.

Objective To analyze the expression of long non-coding RNA ( lncRNA) in renal clear cell carcinoma ( RCCC ) , the association of lncRNA with RCCC, as well as the role of lncRNA in the diagnosis and treatment of RCCC.Methods Forty fresh RCCC tissues and their normal adjacent tissues were collected from March 2012 to June 2013, and total RNA was extracted using Trizol reagents, purified and tested by denaturing agarose gel electrophmesis and NanoDrop 1000.Through Arraystar Human LncRNA Microarray, the different expression of lncRNA between RCCC and normal adjacent tissues was screened. RT-qPCR was used to verify the expression of lncRNA in 40 pair RCCC tissues and normal adjacent tissues. The receiver-operating characteristic ( ROC ) curve was adopted to verify the diagnostic efficiency of the selected lncRNA.Results LncRNA expression profile showed 1 787 lncRNA with expression alteration in two fold or above, up-regulated and down-regulated candidate lncRNAs were 941 and 846 respectively. Compared with the adjacent tissues, NR_034095 and NR_038974 were up-regulated in RCCC, and ENST00000571724 and ENST00000566575 were down-regulated, which were consistent with the microarray analysis.By the ROC curves of NR_034095, NR_038974, ENST00000571724 and ENST00000566575 to discriminate the RCCC from normal adjacent tissue, the area under curve was 0.928 ( 95%CI 0.873 -0.984), 0.759 (95%CI 0.647-0.871), 0.833 (95%CI 0.747-0.919) and 0.887 (95%CI 0.815-0.959 ) , respectively.Conclusions NR _ 034095, NR _ 038974, ENST00000571724 and ENST00000566575 are significantly differently expressed in RCCC.The different expressed lncRNA might be closely related to the process of RCCC, and may be used as a new candidate target for molecular diagnosis and gene therapy of RCCC.
