Objective To evaluate the clinical effect of integrated traditional and western medicine in the treatment of serious ulcerative colitis. Methods Salicylate and cortical hormone were given to patients in acute phase, supplemented by oral administration of herbal medicine and retention enema of Kushenhuaihua concoction. During the period of remission, the patients were treated mainly with Jianpiling supplemented with salicylate for at least half a year. Results In 55 patients receiving conservative treatment, 35(63.6%) recovered completely, 18(32.7%) showed effective result, only 1 patient died and another showed ineffective result (1.8%). Five patients underwent surgical treatment, among them 4 were completely relieved. Long-term follow-up showed that in 67.4% of patients the symptoms were completely relieved, and in 2.3% of patients malignant degeneration occurred, 4.7% of the patients died, and 6.9% of the patients underwent operative treatment. Conclusion The effects of integrated traditional and western medicine treatment in patients with serious ulcerative colitis is superior to western medicine aloner as evidenced by a decrease in mortality and necessity of operation.

Objective To observe the effects of salvianolic acid B on the stem cells factor(SCF) secretion and mRNA expression of mesenchymal stem cells(MSCs) in vitro.Methods MSCs were isolated,cultured and purified in vitro by adherent culture.The 3rd passage of MSCs was chosen to undergo the experiments.MSCs were cultured in five groups of lower glucose DMEM media containing different concentration of salvianolic acid B as follows: group of control(no salvianolic acid B added),four groups of salvianolic acid B treatment(0.03?g/ml,0.3?g/ml,3?g/ml and 30?g/ml of salvianolic acid B were added,respectively,into the lower glucose DMEM media).The quantities of SCF were measured by ELISA in the supernatant of cultured MSCs harvested at 24h,48h and 72h culturing.The expression of SCF mRNA in the supernatant of cultured MSCs harvested at 24h,48h and 72h culturing were analyzed with reverse transcription-polymerase chain reaction.Results RT-PCR assay displayed that dissolvent and membrane type of SCF mRNA expressed in MSCs basically.The expression of SCF mRNA and the quantities of SCF increased significantly(compared with the control group,P0.05).Conclusion Salvianolic acid B may promote the secretion of SCF and reinforce the expression of SCF mRNA of MSCs,implying that SCF might play an important role on the treatment of myocardial ischemia with the traditional Chinese medicine Salviae miltiorrhizae.

Objective To evaluate the outcomes of cardiac surgery in neonates weighing less than 2500g and premature infants. Methods From January 2000 through March 2005, 36 consecutive critically symptomatic neonates (26 males, 10 females) weighing less than 2500g underwent cardiac surgery at our center. Median gestational age was 34 weeks with 24 (70.6%) premature (≤37 weeks). Median age at operation was 15.5 days (from 4 days to 68 days). Median weight was 2120g (from 700g to 2500g). Indications for surgery were: persistent ductus arteriosus (PDA, n=15), coarctation of the aorta (CoA, n=3), transposition of great arteries with severely hypoplastic aortic arch (TGA/HAA, n=1), ventricular septal defect (VSD, n=10), pulmonary atresia with intact ventricular septum (PA/IVS, n=5), total abnormal pulmonary venous return (TAPVR, n=2). The heart functions of all patients were assessed in NYHA class IV and 7 patients (19.4%) were intubated pre-operatively. 18 cases (50%) needed extracorporeal circulation and deep hypothermia with circulatory arrest was used in 6 patients. Results The overall mortality was 11.1%. The causes of death were left heart failure in 1 patient and multiorgan failure in 2 and hypoxmia in 1. Mean extracorporeal circulation time was 92 min (from 72 min to 198 min). Mean aortic cross-clamping time was 76 min (from 46 min to 158 min). Mean deep hypothermia with circulatory arrest Peritoneum dialysis was carried out in 5 cases. Mean follow-up period was 22. 3 months (from 2 months to 46 months). 2 patients underwent reoperation and catheter intervention respectively. The heart functions of 26 patients (81.4%) were in NYHA class I at the latest clinical examination. Conclusion This study suggests that complete repair of simple and complex congenital heart diseases can be performed effectively in low birth weight neonates with acceptable mortality and morbidity. Low weight alone should not be considered as a contraindication to surgery in these patients. It is recommended that such neonates undergo early surgical correction rather than prolonged conservative palliation.

As the third-generation bisphosphonate,zoledronic acid (ZOL) has been widely used for the treatment of skeletal-related events in breast cancer.Previous studies have demonstrated that ZOL has antitumor activitie in breast cancer.ZOL can induce direct and indirect antitumor activities through inducing apoptosis,inhibiting the proliferation,adhesion and invasion formation of bone microenvironment which is conducive to tumor growth,besides inhibiting angiogensis and modulating immune response.Also evidences of synergistic antitumor effects are found when ZOL combines with radiotherapy and chemotherapy,endocrine,and targeted drugs.The observed improvement in antitumor effects by using combination therapy with ZOL in breast cancer is currently being verified through additional clinical trials.

Objective To explore the changes in angiotensin Ⅱ(AngⅡ)produced by Langerhan islets of Syrian hamsters after blockage of renin-angiotensin system(RAS)by different inhibitors.Methods Islet cells from Syrian golden hamster were isolated and purified,and angiotensin Ⅰ was added.The experiment was then divided into six groups:control group(PBS was added),captopril group,chymostatin group,aprotinin group,?-antitrypsin group,and captopril+chymostatin group(according to inhibitors added).The content of AngⅡ in supernatant was detected by enzyme-linked immunosorbent assay(ELISA).Results Compared with control group,the AngⅡ content decreased by 42.50% and 50.94% in captopril group and chymostatin group,respectively(P

Objective To investigate the effects of low intensity pulsed ultrasound ( LIPU ) on articular car-tilage injury in rabbits. Methods Ten adult New Zealand white rabbits with bilateral, full-thickness osteochondral defects in the cartilage surfaces of intercondylar fossas were used as model. The left knees in these rabbits treated with LIPU were used as experimental group. The right knees treated with sham intervention were used as controls. All the rabbits were sacrificed at the 8th week postoperation for gross appearance grading, histological grading and semi-quan-titation of proteoglycan in the repairing tissue. Results Compared with controls, defects treated with LIPU im-proved significantly as shown by gross appearance grades, histological grades and optical density of toluidine blue at the 8th week postoperation (both P <0.05). Conclusion LIPU could accelerate repairing of articular cartilage in-jury.

This study aims to observe different factors which affected the bionic enzymatic hydrolysis of icariin into baohuoside I and to optimize the reaction conditions in order to provide research foundation for building a novel bionic enzymolysis drug delivery system. To simulate the environment in vivo, 37 degrees C was set as the temperature and artificial intestinal juice and gastric juice were selected as the buffer solutions. Taking the conversion of baohuoside I as index, the effects of the kinds of enzyme, enzyme activity, substrate concentration, reaction time, pancreatin in artificial intestinal juice and surfactant on the conversion of baohuoside I were investigated. The results showed that cellulase, beta-glucosidase and snailase were all inactive in artificial gastric juice and no baohuoside I generated. Pancreatin in artificial intestinal juice couldn't significantly influence the activity of beta-glucosidase or snailase (P > 0.05), but noticeably decrease the activity of cellulase (P < 0.05). In artificial intestinal juice, the conversion of baohuoside I was highest by using beta-glucosidase, and the optimum reaction conditions were determined as follows: enzyme activity 10 U x mL(-1), substrate concentration 1 mg x mL(-1), 3 g x L(-1) rhamnolipid and reaction time 3 h. Under this condition, the conversion of baohuoside I was 99.8%.

ObjectiveTo assess and compare the resting energy expenditure measured by indirect calorimetry (MREE) and calculated with Harris-Benedict formula adjusted with correction factors (CREE) in critically ill surgical patients receiving mechanical ventilation,and to evaluate the relationship between resting energy expenditure and the severity of diseases.MethodsFrom August 2008 to February 2010,21 patients fitting the inclusion criteria were selected into the present study.The data of the patients were collected to calculate acute physiology and chronic health evaluation Ⅱ score ( APACHE Ⅱ score) and multiple organ dysfunction score ( Marshall score).MREEs were measured using indirect calorimetry of a MedGraphics CCM/D System,and CREEs were calculated at the same time with the Harris-Benedict formula.ResultsWithin the week of nutrition support,the mean CREE of the 21 patients was significantly higher than the mean MREE [ ( 8305.09 ± 1392.76 ) kJ vs.(6544.84 ±2079.65) kJ,P =0.000].The differences between MREE and CREE were statistically significant on the 0 ( P =0.000),1 ( P =0.000 ),2 ( P =0.000 ),and 4 day ( P =0.003 ) of nutritional support.There was no correlation between MREE and CREE (r =0.064,P =0.408 ),nor between MREE and APACHE Ⅱ ( r=-0.045,P =0.563 ).There was a correlation between MREE and Marshall score (P =0.001 ),but the correlation coefficient was low ( r =0.263).ConclusionsThe Harris-Benedict prediction modified with correction factors for severity of diseases overestimates the resting energy expenditure of critically ill surgical patients.Indirect calorimetry is a more accurate method for determining resting enenrgy expenditure.
