Objective To screen and identify the anomously expressed proteins at protein level in colon mucosa of diarrhea-predominant irritable bowel syndrome(D-IBS)patients and healthy individuals.Methods Four D-IBS patients and four healthy individuals were included in the study.Biopsies of mucosa at the ileocecal junction and sigmoid colon were performed via colonoscopy.The specimens were cleaned with ice cold saline which contained 0.1% PMSF,and were snap frozen in liquid nitrogen.The two-dimensional gel electrophoresis(2-DE)was used to screen the anomously expressed proteins,and the two proteins which presented the greatest changes in each group were identified by mass spectrometry method.Results Proteomics maps of human colon mucosa were obtained successfully with 2-DE.Average protein spots were 336 in normal control group,and the matching rate among them was 92%,while in D-IBS group,the average protein spots were 426,and the matching rate was 95%.The average matching rate between the test group and the control group was 74%.It was found that the volume value of 24 proteins spots changed more than two folds.The protein expression was found to decrease in 3 spots and increase in 21 spots.Four proteins were chosen for analysis with mass spectrometry analysis.The two up-regulated proteins were identified as Immunoglobulin J chain and heat shock protein 27,while the other two down-regulated proteins were identified as hemoglobin beta subunit and fructose-bisphosphate aldolase A.Conclusion With 2-DE,proteomics maps of human colon mucosa have been obtained successfully.The proteome expressions of colon mucosa in D-IBS patients are remarkably different from that of the healthy individuals.The four identified proteins may play a certain role in the pathogenesis of D-IBS.

The level of lipid peroxides (LPO)and copper-zinc containing superoxide dismutase(SOD-I) in the gastric mucosa and serum was determined in 141 samples from 25 patients after conventional subtotal gastrectomy (11 cases of Billroth I and 14 cases of Billroth Ⅱ and 11 patients after pylorus and antroseromuscular flap preserving gastrectomy (PAFPG).Those of 11 normal subjects were examined likewise to serve as control.It was found that;1.The average LPO level was much higher and the average SOD-I level much lower in the gastric mucosa after conventional subtotal gastrectomy especially the Billroth type Ⅱ than in those after PAFPG.2.In 36 specimens of stump mucosa,the average LPO level was significantly higher in the tissue around the anastomotic ring than in that of the body of the stump;no marked difference of SOD-I level between the 2 was revealed.3.The LPO value in the stump mucosa was positively correlated to and the SOD-I value negatively correlated to the pH value of gastric juice.Thess findings suggest that the reaction of oxygen free radicals in the stump-mucosa may be influenced by the intragastric pH or by the type of digestive continuity reconstruction,and that the reaction of free radicals specially lipidperoxidation may play a role in the pathogenesis of the lesions in the anastomotic stoma.

0.05).Large amounts of E.coli and intestinal aerobics such as Veillonella spp.,Bacteriodes fragilis,and Clostridium spp.were detected in patients with B-Ⅰ and B-Ⅱ especially the latter but not found in those with PAFPG.These findings suggest that intragastric bacterial overgrowth,can exist in the hypoacidic stumps in the first one to three years afte conventional gastrectomy especially after B-Ⅱ,no such occurrence is found in those after PAFPG since it only moderately reduces the intragastric acidity.

Objective To report our clinical experience on laparoscopic common bile duct exploration and primary suture.Methods From March 1992 to December 2006,669 cases of laparoscopic common bile duct exploration and primary suture were carried out in our hospital.Cholangioscopic lithotomy,electrohydraulic lithotripsy,biliary dilation,bile duct drainage,or biliary stenting were performed on the patients.Results The surgeries were completed successfully in 643 of the 669 cases(96.1%).Biliary leakage was observed in 17(2.5%) cases after the operations,and was cured by nasobiliary and intra-abdominal drainage.2(0.3%) patients developed mild stenosis of the bile duct without showing any symptoms.4(0.5%) had residual stones and were cured by a second laparoscopic surgery.The fine duct fell off in 2 cases(0.3%),and was re-fixed by a re-operation.581 of the cases achieved a 6- to 48-month follow-up(mean,25.6 months),during the period,no patient developed biliary leak,and stenosis or hemorrhage of the common bile duct.Conclusion Laparoscopic common bile duct exploration and primary suture is safe and effective.

ObjectiveTo investigate the adjuvant effect of heatshock protein 110(HSP110) on the immune responses induced by an altered peptide ligand of human papilloma virus type 16 E711-20 peptide (HPV16E711-20).Methods The complex of HSP110 and an altered peptide ligand of HPV16E711-20 was constructed in vitro.Fifteen 6-week-old C57BL/6 female mice were randonly and equally divided into 3 groups,including complex group,ligand group,and phosphate buffered solution (PBS) group,to receive intraperitoneal immunization with the complex (100 μg),peptide (10 μg),and PBS (100 μl) respectively.Immunization was carried out with an interval of 2 weeks for 2 times.Two weeks after the last immunization,the mice were sacrificed followed by the isolation of splenocytes.MTT assay was performed to evaluate the proliferation activity of splenocytes,intracellular staining for interferon(INF)-γ to detect cytotoxic T lymphocytes (CTLs),standard chromium-51 (51Cr) release assay to estimate the lethal effect of specific CTLs on target cells.Statistical analysis was performed by using t test with SPSS 10.0 software.Differences were considered as statistically significant when the P value was less than 0.05.ResultsA significant increase was observed in the proliferation index ( 1.87 ± 0.122 vs.0.32 ± 0.071,t =4.01,P ＜ 0.01 ) of,and percentage of CD8+IFN-γ+ T lymphocytes(3.9％ vs.0.4％,t =3.88,P ＜ 0.01 ) among splenocytes from the complex group compared with the ligand group.At the effector-to-target ratio of 100 ∶ 1,50 ∶ 1,25∶ 1 and 12.5 ∶ 1,the death rate of target cells was 54.7％,72.2％,61.5％ and 39.8％ respectively after incubation with CTLs from the compleximmunized mice,higher than that from the ligand-immunized mice (35.2％,49.3％,28.1％,17.4％,respectively).ConclusionHSP110 could enhance the immunological effect of the altered peptide ligand of HPV16E711-20,and can serve as an immunological adjuvant.

Background: The quality of life has been greatly influenced and the cost of medical expenses is very high in patients with irritable bowel syndrome (IBS). The etiology and pathogenesis of IBS are still unclear, and the prevention and treatment of this disease still lack of effective methods. Objective: To explore and analyze the effects of Tiaohe Ganpi Hexin Decoction (TGHD), a compound traditional Chinese herbal medicine for regulating the liver and spleen, on IBS patients with diarrhea. Design, setting, participants and interventions: All 40 IBS patients came from the First Hospital of Jinan University, Guangzhou Red Cross Hospital, and the First Affiliated Hospital of Guangzhou University of Chinese Medicine, and were randomly divided into two groups. Patients in the treatment group (n=20) were given TGHD, while those in the control group (n=20) were prescribed oral pinaverium with a four-week treatment period. Main outcome measures: Traditional Chinese medicine (TCM) syndrome score, total obviously effective rate, disappearance rate of symptoms, and clinical symptom score in the two groups were evaluated before and after four-week treatment. Results: After the treatment, TCM syndrome scores in both groups were decreased (P<0.01), and the TCM syndrome score in the treatment group was significantly lower than that in the control group (P<0.01). There was a significant difference in the total obviously effective rate between the two groups (P<0.01), and the total obviously effective rates in the treatment and control groups were 85%(17/20) and 45%(9/20) respectively. The disappearance rates of abdominal pain, abdominal distention, poor stool output, stool frequency, stool character and mucous stool in the treatment group were higher than those in the control group (P<0.05). The symptom scores of abdominal pain, abdominal distention, poor stool output, stool frequency, stool character and mucous stool in the treatment group were lower than those in the control group (P<0.05). Conclusion: TGHD can significantly improve the clinical symptoms in IBS patients with diarrhea.

BACKGROUND: Bone marrow inhibition is a predominant side effect caused by the drugs for anti-tumor.OBJECTIVE: To observe the intervention effect of traditional Chinese medicine qiongyugao on bone marrow inhibition induced by chemotherapy in experimental mice with pulmonary adenocarcinoma.DESIGN: Randomized controlled trial.SETTING: Medical College of Jinan University.MATERIALS: The experiment was completed in the Central Laboratory of Medical College of Jinan University from March to October in 2001. Fortyeight healthy, aged 6 to 8 weeks C57/BL mice were involved.METHODS: The mouse model with pulmonary adenocareinoma was made with the method of inoculability of cancer cell, and then the models were group: On the following day of inoculation, 0.2 mL normal saline was used by gavage, and normal saline was injected intraperitoneally at the dosage of amine 20 mg was diluted into 0.2 g/L with normal saline, and performed intraperitoneal injection at the dosage of 5 μL/g, once per day, and 0.2 mL platinum diamine was used as in chemotherapy group and 0.2 mL qiongyugao was administered by gavage at the same time once per day. Peripheral erythrocyte, leukocyte and blood platelet, and karyota in bone marrow counting were detected on the 21 days after administration.MAIN OUTCOME MEASURES: Peripheral erythrocyte, leukocyte and blood platelet, and karyota in bone marrow counting of the mice in each group.RESULTS: Eleven mice failing to have tumor in tumor assessment were excluded from the sample, including 3 in the control group, 4 in the chemotherapy and 4 in the combination group. During the experiment,there were 2 mice dying in each group of the control group and chemotherapy group. Totally 11 mice in the control group, 10 in the chemotherapy group and 11 in the combination group entered the result analysis. Erythrocyte, leukocyte and blood platelets in the combination group and control group were all significantly higher than those in the chemotherapy group [erythrocyte: (8.54 ±0.81 ), (8.65 ±0.77), (4.56 ±1.00) ×1012 L -1;leukocyte:(9.04 ±0.60), (9.14 ±0.71), (3.31 ±0.96) ×109 L -1;blood platelets:(949.09±111.31 ), (955.54±87.13), (399.30±131.36)× 109 L-1 ,P ＜ 0.01]. The number of karyota in bone marrow in the chemotherapy group was significantly lower than those in the combination group and control group [(5.30±1.12),(10.51±1.15),(14.36±1.02)]×106,P ＜ 0.01); while the number of karyota in the control group was higher than that in the combination group (P ＜ 0.05).CONCLUSION: Qiongyugao can enhance the counting of erythrocyte,leucocyte, blood platelets of peripheral blood and karyota in bone marrow after chemotherapy in mice with pulmonary carcinoma, improve the inhibition of bone marrow induced by chemotherapy, but can not reverse it completely.
