Objective To investigate the clinical characteristics of imflamatroy bowel disease (IBD) and the risk factors in developing eoloreetal cancers. Methods Five hundred and thirteen patients with IBD were consecutive collected from Jan. 1996 to Oct. 2007. The history database of these patients was established. The items including demography features, morbidity, diagnosis, the related risk factors, the treatment and outcomes were analyzed. Results Two hundred and forty two out of 513 patients were ulcerative colitis (UC). Of which 4 patients (1.65%) developed cancer and 4 (1.650%) were confirmed with precancer. But none of the 271 patients with Crohn's disease (CD) de-veloped cancer. The Logistic regression analysis showed that weight loss, complications and relapse might be the potential risk factors of the cancer. Conclusions In clinical, the probability that develope to cancer in patients with UC is higher than that in patients with CD. The main risk factors are frequent relapse, weight lost and complications.

Objective To analyze the relationship between T lymphocyte subsets,neutrophil to lymphocyte ratio(NLR) and lung cancer pathological classification,clinical stage of non-small cell lung cancer.Methods The proportion of T lymphocyte subsets in 60 patients with lung cancer were detected by flow cytometry,the NLR were measured by blood sampling.Results The proportion of CD4+T lymphocytes,the proportion of CD8+T lymphocytes,CD4+/CD8+ and NLR in patients with lung adenocarcinoma,lung squamous cell carcinoma,small cell lung cancer patients were not statistically significant.The proportion of CD4+T lymphocytes and CD4+/CD8+ in patients with advanced non-small cell lung cancer(stage Ⅲ~Ⅳ) were lower(P<0.05) than in the early group(stage Ⅰ~Ⅱ).The proportion of CD8+T lymphocytes and NLR in patients with advanced non-small cell lung cancer(stage Ⅲ~Ⅳ) were higher(P<0.05) than that of early stage group(stage Ⅰ~Ⅱ).Conclusion The T lymphocyte subsets and NLR in the peripheral blood of non-small cell lung cancer patients have a certain correlation with the clinical stage of non-small cell lung cancer,which can be used as a reference index for clinical staging.

Objective To investigate the clinical effect of laparoscopic operation and laparotomy in the treat-ment of uterine fibroids.Methods A retrospective analysis of uterine fibroids and requests to retain the clinical data of 380 cases of uterine of patients,according to treatment methods,they were divided into laparoscopic myomectomy group (group A)and cesarean section uterine fibroids removed surgery group (B group),there were 190 cases,two groups of patients,surgery,clinical effect were analyzed.Results In group A,operation time,postoperative exhaust time,postoperative ambulation time,postoperative VAS score,duration of hospitalization,injection of analgesics appli-cation proportion were (96 ±35)min,(24 ±8.5)h,(12 ±4)h,(2.0 ±1.5),(4.0 ±1.2)d,17.8%,patients in the group B respectively (98 ±28)min,(40 ±12)h,(20 ±8)h,(6.0 ±1.3),(8 ±2)d,84.6% there was a significant differences between the two groups (t=-2.558,33.96,45.810,50.571,34.120,χ2 =169.89,all P<0.05);group A and group B,the amount of bleeding were (186 ±78)mL and (175 ±85)mL,with no significant difference between the two groups (t=1.911,P>0.05);group A,the complication rate was 7.34%,lower than the 12.6%in the group B,there was significant difference between the two groups (χ2 =3.923,P<0.05).Conclusion Laparoscopic myo-mectomy in treatment of uterine fibroids,good effect,less trauma,quicker recovery,shorter hospitalization time of patients,should be further popularized in clinic.

Objective To observe the change of sinus heart rate turbulence (HRT) and its relation to left ventricular systolic function (LVSF) in patients with acute coronary syndrome (ACS). Methods The 103 ACS patients and 62 healthy subjects were enrolled in this study, all of them received 24-hour Holter monitor. And the values of turbulence onset (TO), turbulence slope (TS)and heart rate variability (HRV) SDNN were calculated according the Holter records. The clinical information, left ventricular ejection fraction (LVEF) and left ventricular end diastolic diameter (LVEDD) were recorded. Then the ACS patients were divided into acute myocardial infarction (AMI)group and unable angina pectoris (UAP) group according to the cardiac enzymes and electrocardiogram. Results The value of TO was significantly higher in ACS group than in control group [(0.17±1.40)％ vs. (- 0.26±0.99)％, P＜0.05], and TS was significantly lower in ACS group than in control group [R-R interval:(0.88±2.51) ms vs. (2.60±2.76) ms, P＜0.01].There were significant differences in TS, LVEF and LVEDD between AMI group and UAP group (all P＜0.01), but there were no differences in HRV and TO between the two groups. TS was positively correlated with LVEF (r=0.21, P＜0.05), while TO was negatively correlated with LVEF (r=-0.26, P＜0.05) by Spearman correlation analysis. Conclusions HRT is significantly blunted in ACS patients and can evaluate cardiac autonomic function. It may be as a predictor of LVSF in ACS patients.

Objective To evaluate the advantages and disadvantages of Narcotrend(NT)in monitoring the depth of anesthesia when compared with the bispectral index.Methods Eighty ASA Ⅰ or Ⅱ patients of both sexes,aged 19-60 yr,undergoing elective surgery,were enrolled in this clinical study.Propofol was given by target-controlled infusion(TCI).After the initial target plasma concentration of 2.1 μg/ml was achieved,the concentration was increased by 0.3 μg/ml every 30 s until the patients lost consciousness.Then the effect-site concentralion of propofol was increased by 0.5μg/ml to maintain anesthesia and rocuronium 0.8 mg /kg was injected intravenously 30 s later.Tracheal intubation was performed 3 min after rocuronium injection.Mean arterial pressure (MAP),HR,NT value and BIS value were measured before TCI of propofol(baseline),al loss of consciousness,immediately before rocuronium administration,2 min after rocuronium administration,during intubation,and at 1 and 3 min after intubation.Results NT and BIS values were significantly decreased at loss of consciousness as compared with the baseline value(P ＜ 0.01).NT and BIS values were significantly lower at 2 min after rcuronium administration than before rocuronium administration(P ＜ 0.05).Compared with that before intubalion,HR and MAP were significantly increased during intuhation,and at 1 and 3 min after intubation,while no significant change was found in NT and BIS values(P ＞ 0.05).Conctusion NT can monitor the sedative effecl induced with TCI of propofol accuralely,the myoelectric activity exerts an obvious effect,and the accuracy of NT for monitoring the analgesic effect is lower.NT and BIS are comparable with respect to the advantages and disadvantages.

0.05).However,major vascular complications occurred only in the femoral group(3.9%).Conclusion Transradial LM PCI is as fast and successful as the femoral approach and results in fewer vascular complications.

Objective To explore how different sex affect the clinical feature and apneic event,sleep time in patient with sleep apnea hypopnea syndrome.Methods According to the analysis of polysomnography(PSG),133 male and 47 women with chief complain of snoring were divided into four groups simple snor,mild SAS,moderate SAS and severe SAS group.Compared related clinical feature and PSG data among them ,we found the difference in it.Results Male patient have more complication than female patient (P

Objective To compare the effect of different dosage of verapamil and a cocktail therapy(verapamil 200 ?g plus nitroglycerin 200 ?g) in the prevention of radial artery spasm(RAS) during transradial PCI.Methods It is a prospective,randomized and double-blind clinical trial.Patients who received transradial coronary intervention were divided into three groups: group A(verapamil 200 ?g),group B(verapamil 1mg) and group C(verapamil 200 ?g plus nitroglycerin 200 ?g).Different drug protocols were given randomly to the patients after sheath insertion.The diagnostic criteria is clinical definition of RAS documented by angiography.The incidence of RAS and adverse effects in each group was compared.Results A total of 621 patients were enrolled,and there were 205 in group A,207 in group B and 210 in group C.The baseline characteristics were of no difference among the three groups.Univariate analysis showed that the incidence of RAS in group A is higher than that in group B(17.1% vs.10.2%,P=0.045) and in group C(17.1% vs.9.5%,P=0.029),but there was no statistical difference in the RAS incidence between group B and C(10.2% vs.9.5%,P=0.870).Binary logistic regression analysis showed that the relative risk of RAS in group B decreased by 32.1% compared with group A(P=0.038),and the relative risk in group C decreased by 43.8% compared with group A(P=0.017).The incidences of adverse effect were similar in groups A and C,but was higher in group B when compared with group A(9.7% vs.2.4%,P=0.003) and C(9.7% vs.3.8%,P=0.019),respectively.Conclusion Verapamil 200 ?g plus nitroglycerin 200 ?g is recommended to prevent RAS during transradial coronary intervention in Chinese.

Objective To assess the efficacy and safety of two kinds of arterial suture-mediated closure devices (Angioseal and Perclose) in patients after coronary arteriography(CAG) and percutaneous coronary intervention (PCI). Methods 1?020 patients (672 male, 348 female, mean age 57.8?2.4 yr) undergoing CAG or PCI were randomized into either the Angioseal group (CAG 380, PCI 120) or the Perclose group (CAG 392, PCI 128). The procedural success rate and occurance of local complications were compared between the two groups. Results Both kinds of devices had a high success rate (Angioseal 94% vs Perclose 96%) and there was no statistical difference between them. There were five cases of hematoma and no pseudoaneurysm in the Angioseal group. On the other hand, there were four cases of hematoma and three cases of pseudoaneurysm in preclose group. There was no statistal difference in terms of local complications between the 2 groups. Conclusion Both kinds of arterial suture-mediated closure devices (Angioseal and Perclose) are feasible and safe for patients undergoing CAG and PCI.

Objective To evaluate the efficacy and safety of facilitated PCI(low-dose rt-PA combined with percutaneous coronary intervention)in acute myocardial infarction(AMI).Methods One hundred and sixteen patients with AMI were divided into low-dose facilitated PCI group(n=69)and direct PCI group(n=47).69 patients in low-dose facilitated PCI group were treated with an intravenous drip of 50 mg rt-PA and PCI,while 47 patients in direct PCI group were treated with PCI.The rates of recanalization before and after PCI,and the left ventricular ejection fraction(LVEF)and major hemorrhage and major adverse cardiac events(MACE)in hospital were compared in two groups.Results There was no significant difference in the interval from hospitalization to the PCI between low-dose facilitated PCI group and direct PCI group.Compared with direct PCI group,the rates of recanalization and TIMI grade 3 before PCI were significantly higher in low-dose facilitated PCI group(44.7% vs 21.7%,P
