Objective To evaluate clinical and endoscopic characteristics of ischemic colitis (IC), and to explore the methods for the early diagnosis of IC. Methods Thirty six patients diagnosed as IC in Hua dong Hospital from June 1975 to December 2000 were reviewed. All patients underwent colonoscopy with biopsy within 5 days of symptoms, and repeated the exam in 2 weeks to 2 months. Results Of the 36 cases (12 men and 24 women, average age 60.5 years old, range 35 84), 31 were over 50 years of age. IC usually presented with sudden onset of left lower quadrant abdominal pain, diarrhea and hematochezia. Patients' ischemic lesions were most often on the left colon. It consisted transient or reversible colitis in 30 cases, stricture colitis in 5 cases and gangrene colitis in only 1 case. Morphologic changes varied with the duration and severity of the injury. Conclusion Colonoscopy with biopsy is the main method for the diagnosis of IC. It should be performed in the early stage of the onset of symptoms.

Objective To explore the effect of rehabilitation on pneumonia in children with cerebral palsy (CP).Methods60 CP children with pneumonia were randomly divided into the control group and rehabilitation group with 30 cases in each group. All children in two groups received active support therapy but those in the rehabilitation group were added with rehabilitation treatment.ResultsThe time of body temperature decline, alleviation of cough and expectoration, role disappear of the rehabilitation group were shortened compared with that of the control group ( P<0.05).ConclusionRehabilitation treatment is helpful for treatment of pneumonia in CP children.

Objective To evaluate the clinical and endoscopic features of ulcerative colitis(UC). Methods The cases of UC were collected from 1975 to 2001. According to the diagnostic criteria of Chengdu conference, 486 and 490 patients were diagnosed as UC in our hospital from 1975 to 1994 and from 1995 to 2001 respectively. Their records were retrieved and the data were analyzed for sex, age, presentation, the course of the illness and lesion range. Results In the two groups from 1975 to 1994 and from 1995 to 2001, the proportion of patients diagnosed as UC under colonoscopy was increased from 3.51% to 4.44%. The ratio of male to female was 1.67 and 1.25 respectively. The mean age at the diagnosis increased from 42.4 years old to 51.5 years old, and the peak age was between 30 and 49 years old, between 40 and 49 years old and greater than 60 years old respectively. The typical clinical manifestations of UC were bloody mucopurulent stool, diarrhea and abdominal pain. Proctosigmoiditis or proctitis was found in 269 patients (55.4%) and 316(64.5%), left side colitis in 84(17.3%) and 68(13.9%), pancoltitis in 58( 11.9% ) and 70(14.3%) respectively. In the two groups, there were 437( 89.9% ) and 443(90.4%) patients who had the course of less than 10 years respectively. The definitive diagnosis of UC was dependent on biopsy. Conclusions The lesions of UC are commonly located in the left side colon, the course of UC is short, the age of onset is relatively high in the middle and old aged group, and the prevalence of both malignancy and complications is low. Colonoscopy with biopsy is considered to be the major means for the diagnosis of UC.

Objective To study the clinical significance of P - selection expression in children with viral encephalitis and the correlation between this expression and the cerebral infarction with critical viral encephalitis. Methods Flow cytometric was employed to detect the expression of P- selection on the surface of platelet membrane in 44 children with viral encephalitis(20 light patients and 24 critical patients) and 20 healthy control children. The area of the cerebral infarction was determined by computed tomographic scan in 20 patients with critical viral encephalitis. The correlation between the two variables was analyzed. Results The expressions of P - selection on the surface of platelet membrane on less than 5 days and on 2 weeks after the onset of viral encephalitis were significantly higher in critical patients than those in normal control children and light patients( P

?-lactamase inhibitor research is popular for its potential on ?-lactam antibiotics resistant strain.A ?-lactamase binding peptide SIPIS04-01 was obtained by the yeast two-hybid system.In vitro assay showed that it can inhibit the ?-lactamase activity.In order to improve the expression level of the recombinant peptide,a two-copy expression plasmid pYG563 was constructed by random orientation tandem repeat method after codon modification,the two-copy plasmid was successfully expressed and the product was increased by 48.4% than that of one-copy plasmid.Purified peptide showed inhibitory activity against TEM-1 ?-lactamase in vitro and the inhhibitory constant Ki was measured.

Aim The effects of midazolam on the whole-cell sodium currents in rat sympathetic neurons were studied to explore the mechanisms where by midazolam mediates hypotension. Methods Whole-cell patch-clamp recordings were performed on enzymatically isolated rat superior cervical sympathetic neurons. Results Midazolam dose-dependently blocked the whole-cell sodium currents evoked by a voltage step to 0 mV from a holding potential of -80 mV with a mean drug concentration required to produce 50% current inhibition (IC50) values of 18.35 ?mol?L-1; Clinically relevant concentration of midazolam(0.3 ?mol?L-1) reduced sodium peak currents by 19.98%(P

Objective:To investigate the therapeutic efficacy of double-J catheter in treatment of renal tuberculosis(TB)and in rescuing the structure and function of the kidney.Methods:Thirty-four patients with renal TB(22 combined with single side hydronephrosis)were divided into 2 groups randomly.Group A were treated with antituberculous therapy and group B with antituberculous therapy combined with pre-treatment with double-J catheter.All 34 patients were followed up for 3 months and were re-examined.Results:The results of B ultrasound,intravenous urogram(IVU),CT and isotope nephrogram were comparable between the 2 groups before treatment,and the results were significantly different between the two groups after 3 months'drug treatment(P
