Objective To evaluate the clinical outcome of severe ulcerative colitis(UC)and to find the factors related to treatment and outcome.Methods Forty one hospitalized patients with UC during 1988-2004 were retrospectively reviewed.Data were recorded including the onset,symptoms,signs, laboratory,endoscopic,radiologic and pathologic findings,as well as the processes of clinical treatment. The patients who undergone surgery were also analysed.Results Forty one of 144(28.5%)hospital ized patients were suffered from severe UC,and among them 92.7%(38/41)had pancolitis.The patients who had first onset,chronic persistent,chronic recurrent type were account for 36.9%(15/41),36.9%(15/41) and 26.8%(11/41),respectively.The steroids treatment played the main role in the inducing remission of severe UC(61.0%).Thirty one cases(75.6%)could be relieved by drug therapy.Seven cases(17.1%) were progressed to have operation.The age of early onset,pancolitis,low hemoglobin and serum albumin levels and need of intravenous steroids treatment were associated with the need of surgery.Conclusions Most of the severe UC patients respond well to the medical therapy,but for some non-responding or steroids depending individuals,after a reasonable duration of treatment,surgery should be considered.

Objective:To investigate the characteristic of life events and social support in patients with major depression.Methods:A cohort of 96 major depressed in-patients was assessed on admission. The assessments included Self-Rating Depression Scale (SDS), the Life Events Scale and the Social Support Scale. Ninety-nine healthy subjects were assessed too.Results:Compared with the controls, the patients experienced more stressful life events and got more subjective social support, but the utilization of social support was lower in the patient group. There was no gender difference in the life events and social support. The patients experiencing more life events got less subjective social support and social support as a whole.Conclusions:The depressed patients experience more life events.Social support acts as one of the cushion factors between life events and the onset of major depression.

Objective: To explore the effects of life events, automatic thoughts, social support and coping styles on the severity of depression in major depression at discharge. Methods: A cohort of 97 major depressed in-patients was assessed at discharge. The assessment included Self-Rating Depression Scale (SDS), Life Events Scale, Social Support Scale, Automatic Thoughts Questionnaire and Coping Styles Questionnaire. 100 normal controls were assessed, too.Results: Compared with the controls, the patients experienced more stressful life events in the last one year(t=2.6,P

Objective To investigate retrospectively the clinical characteristics of hospitalized ulcerative colitis(UC)patients of our department,and evaluate the diagnosis and treatment.Methods The cases of UC patients from 1989 to Jun 2005 were retrospectively reviewed. We analyzed the patients' symptoms,diagnosis,and treatment.Results There were 155 cases reviewed. The sex ratio(M/F)was 1.54∶ 1. The average age of patients was 41.8. The peak age of onset was 20~30. 32.3% of our cases were mild type,and 41.3% were moderate type,severe type were 26.5%. Of these pateints,52.9% were pancolitis,and 39.4% were chronic recurrent type,which was very common. Most cases(72.9%)were diagnosed by clinic combined with endoscope and pathology. Most of the severe UC responded well to the drug therapy. Very less(4.5%)had to underwent surgery. No patient died.Conclusion Most of our patients are mild or moderate type,and they respond well to drug some severe and moderate types need steroids and immuno suppressor. The extracolonic manifestation rate(12.9%)and operation rate(4.5%)are low.

Objective To analyze the cause of missing diagnosis for vertebral fracture on lateral chest radiography. Methods Lateral chest radiographies of 1638 hospitalized patients (871 males and 767 females) were retrospectively reviewed for identifying vertebral fractures. Their ages ranged from 50 to 91 years with the mean of 63.5 years. Complains and application for chest radiography in all patients were not related to osteoporosis and vertebral fracture. Vertebral fracture and fracture severity were evaluated using Genant's semiquantitative visual method, taking approximately a 20%-25% vertebral height reduction as mild grade,26%-40% as moderate grade and 41% or greater as severe grade. Evaluation results of the vertebral fracture, original X-ray reports, as well as medical records were compared for further analysis. Results Eighty-four in 1638 patients showed vertebral fractures on the lateral chest radiographies. Of them,vertebral fractures were reported in 30 cases and 54 patients were not reported on their original X-ray reports. There were 63 vertebral fractures in 54 un-reported patients, most of which were single fracture (75% or 47/63). Grade Ⅰ fracture accounted for 54% (34/63), Grade Ⅱ fracture 33% (21/63), while 13% presented grade Ⅲ fracture (8/63). In all 84 patients with vertebral fractures, only 5 cases (6%)underwent dual energy X-ray absorptiometry (DXA) measurement, 5 cases ( 6% ) were recorded to have vertebral fractures on the medical papers, as well as 15 cases ( 18% ) were prescribed drugs related to the osteoporosis when discharged from hospital All drugs prescribed for the 15 patients were limited only to calcium. Conclusions More attention should be paid to osteoporosis by doctors including radiologists.Vertebral fracture on lateral chest radiography should be completely diagnosed, which is helpful for both prevention and treatment.

Objective To observe the effects of the preconditioning of ulinastatin on GES-1 cell injury induced by oxygen and glucose deprivation (OGD). Methods GES-1 cells were cultured in vitro and divided into three groups: normal control group (group N), oxygen and glucose deprivation group (group O), and ulinastatin preconditioning group (group U). The OGD model of GES-1 cells were established by glucose-free medium and three-gas incubator for 6h. Ulinastatin was added to group U 12h before the deprivation of oxygen and glucose. The cell viability and apoptosis were determined by cck-8 and flow cytometry respectively. Western Blot was used to examine the protein expression of Caspase-3 and Cleaved Caspase-3. The TRPV1 mRNA expression was measured by quantitative real-time PCR. Results As compared with group N, the viability of GES-1 was decreased, the apoptotic rate and the expression of Caspase-3 and Cleaved Caspase-3 were increased, and the TRPV1 mRNA expression decreased greatly in group O (P < 0.05). As compared with group O, the aforementioned changes were significantly inhibited in group U. Conclusions Ulinastatin preconditioning could effectively inhibit GES-1 cell injury induced by OGD, which may be related to the inhibition of apoptosis and the upregulation of TRPV1 mRNA expression.

Objective To investigate the effects of recognition of emotional content words on event-related potentials (ERPs) of patients with major depression. Methods ERPs were recorded in 16 patients with major depression and 18 healthy subjects while they performed a visual Chinese emotional content words recognition task. The study used a word identification task consisting of 20% negative and 20% positive words as well as 60% neutral words. Results The ERPs demonstrated similar waveform (N90,P160,N250,P290,N350,P490,N650) between depression patients and normal group, but its components were different. Amplitudes of many ERPs components in patients group were significantly decreased but N250 were significantly increased in FZ and F4 as compared with those of the normal groups (P

Objective:To explore the relation among depression, anxiety, coping styles and personality in patients with major depression.Method:88 patients with major depression were assessed on admission. The assessments included Self-Rating Depression Scale (SDS), Self-Rating Anxiety Scale(SAS),Eysenck Personality Questionnaire and Coping Styles Questionnaire. Nighty normal controls were assessed with the same instruments too.Results:The patients were found having higher scores in Neuroticism and Psychoticism, and lower scores in Extroversion and positive coping styles than normal controls.Higher scores in SDS, SAS, Neuroticism, and Psychoticism, and lower scores in positive coping styles, were found in the patients with anxiety. Significant relationship was found among depression, SAS, Extroversion, and positive coping styles.The last three accounted for 52.0% of the variance of depression.Conclusion:The patients with major depression have high scores in Neuroticism and Psychoticism, and low in Extroversion and positive coping styles.Those with anxiety scored even higher in SDS, SAS, Neuroticism, and Psychoticism, and lower in positive coping styles.The application of little positwe coping styles moy be a part of Extrovision in major depresion.
