Objective To investigate the regulating effect of Jianpixiaoshi Decoction(JPXSD)on gastrointestinal motility in rats of functional dys-pepsia(FD)with spleen deficiency syndrome. Methods Forty healthy male SD rats were randomly divided into four groups:normal control group, model group,model traditional Chinese medicine(TCM)group and model western medicine group. Except for the normal control group,FD model of spleen-deficiency type was established by swimming to exhaustion on alternate days and alternating feeding of cabbage and lard for 25 days. Corre-sponding drugs were then administrated to those four groups:distilled water,JPXSD and Mosapride distilled water solution once a day by gavage for 7 days. Symptoms and body weights of these rats were observed and recorded during the experiment. After the last of drug administration,all groups were fasted for 24 hours. Nutritious semisolid paste marked with ink was given orally to the rats,GER and IPR of 1 hour were detected under anesthe-sia by sodium thiopental and blood were collected at the same time. The concentration of serum SP and SS were measured by ELISA according to the instructions. Results JPXSD improved the symptoms of model rats. Model TCM group showed significantly increased body weight,higher GER, lower IPR,higher serum SP level and lower SS level when compared to model group(P<0.05). Conclusion JPXSD could improve the symptoms of rat with spleen-deficiency,raise its body weight,accelerate the decreased gastric emptying and bring back the hyperactive small intestinal move-ment to normal. The regulating role of JPXSD may be realized through the increase of serum SP level and decrease of SS level.

Background Nerve growth factor (NGF) plays an important role in the maintenance of the tear film stability.It is well known that the damage of ocular surface causes dry eye in the patients with thyroid-associated ophthalmopathy (TAO).However,if NGF is helpful for the stability of tear film is unclear.Objective This study was to investigate the relationship of NGF concentration in tear with tear film stability in TAO patient before and after glucocorticoid treatment.Methods Prospective observational cohort study was designed.This study was approved by the Ethic Committee of Binzhou Medical College,and written informed consent was obtained from each subject before entering this trial.Thirty-eight patients with active TAO and thirty age-and gender-matched controls were enrolled in the study.Prednisolone acetate tablets were administered in TAO patients for 4 weeks at a back-titration regimen.The tear fluid was collected and NGF level was detected by ELISA.Clinical activity score (CAS) was evaluated under the slit lamp lamp.Schirmer Ⅰ test (S Ⅰ t) was performed and breakup time of tear film (BUT) was obtained in controls and patients with active TAO before and 4 weeks after steroid treatment.Results Baseline NGF levels in tear was higher in the patients with active TAO than in the controls (U=-5.026,P＜0.01).NGF level decreased from 46.23 (42.34,51.42) ng/L to 27.45 (19.38,29.12) ng/L 4 weeks after steroid treatment (Z=-6.172,P＜0.05),and CASdecreased significantly from 6 (5,7) to4 (2,5) (Z=-2.496,P＜0.01).SⅠtvalue increased from 6 (4,11) mm to 11 (7,16) mm 4 weeks after steroid treatment (Z =-4.286,P＜0.05),and the BUT prolonged from 5 (3,9) seconds to 11 (6,14) seconds(Z=-3.160,P＜0.05).NGF levels in active TAO was significantly correlated with CAS (r=0.645,P＜0.01),S Ⅰ t value (r =-0.530,P＜0.01) and BUT (r =-0.430,P＜0.01).Conclusions Tear NGF may stabilized the tear film.The application of steroid anti-inflammation drug can reduce the tear NGF level,increase the tear secretion and improve the tear film stability in patients with active TAO.

Objective To investigate complications in patients after noncardiac thoracotomy in hypothyroidism with ST changes. Methods Sixty one patients with hypothyroidism undergoing noncardiac thoracotomy were divided into ST segment change group(28 patients having ST segment depression≥0.05 mV) and controls(33 patients) according to the results of Holter. All patients were added with thyroid hormone, until the function of thyroid gland was normal before thoracotomy. The myocardial ischemia was measured by Holter within 48 hours after thoracotomy. Serum thyroid hormones was examined by radioimmunoassay during, before and after thoracotomy. And cardiovascular events were foliowed-up to hospital. Results Before and after thoracotomy serum TT3 in ST segment change group was (1.30±0.41), (2.09±0.45)nmol/L, TT4 was (80.56±30.28), (84.55±33.57) nmol/L, respectively; compared with the control group[TT3: (1.43±0.52), (2.38±0.51)nmol/L, TT4:(82.70± 29.43), (93.47±35.02)nmol/L], no significant differences were found(all P>0.05). After thoracotomy, 24 patients occurred myocardial ischemia, 10 patients occurred cardiovascular events in ST segment change group; 8 patients occurred myocardial ischemia, a patient occurred cardiovascular events in control group, there were significant differences between two groups(χ2=22.95,10.95, all P<0.05). The positive predictive value of ST segment change in Holter detection was 36% (10/28) recording in cardiovascular events of patients with cardiovascular disease undergoing noncardiac thoracotomy and hypothyroidism, negative predictive value was 97%(32/33). Conclusions Myocardial ischemia and other cardiovascular events tend to occur in hypothyroidism patients with ST segment change after noncardiac thoracotomy. ST segment change of preoperative Hoher detection recording cardiovascular events of hypothyroidism patients undergoing noncardiac thoracotomy has certain predictive value.

Objective:To investigate the feasibility of adipose tissue-derived stem cells(ADSCs) as the seeding cells of skin engineering for skin defect repair. Methods :Adipose tissues were isolated from a SD rat groin, the fat was cut and incubated in a collagenase solution, and then the ADSCs were cultivated in culture medium. The amplified cells in vitro were inoculated in collagen gel to form tissue engineered skin. Fifteen SD rats were randomly divided into three groups: experimental group was treated with ADSCs collagen tissue engineered active skin substitute, and single collagen and blank were served as two control groups. The materials were grafted onto total skin defect wounds on the back of rats in the corresponding group respectively. The effect of wound repair was observed histologically. Results:The time of wound healing in the ADSCs and collagen experimental group, the single collagen control group and the blank control group were (14.3?1.7) days,(16.9?2.5)days,and (21.2?4.2)days respectively, and showed significant differences(P

patients with infective endocarditis were analyzed. Anong them, 75 were patients with congenital heart disease (72 1%), 21 were patients with rheumatic heart disease and 8 were patients without heart disease(7 7%). It is suggested that early diagnoses and treatment of CHD are the main pretective methods for reducing the incidence of IE; the incidence of fever, anaemia, embolism, hepatomegaly and splenomegaly, etc. declines notably; the possibility of excrescence invading aortic valve (44 2%) is higher than that of mitral valve (24 7%), and IE of aortic valve results in heart failure in a short while and the valve replacement should be done as early as possible; positive rate of blood culture declines because of extensive use of antibiotics; appropriate medical treatment combined with active surgical treatment plays an important role in the treatment of IE.
