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.

BACKGROUND:Spinal cord ischemia-reperfusion injury is a serious secondary injury of the spinal cord. Multifactor could contribute to the mechanism of this injury, and many therapeutic measures emerge, but the therapeutic effect is not ideal.
OBJECTIVE:To investigate the protective effects and mechanism of hydrogen-rich saline on spinal cord ischemia-reperfusion injury in rabbits.
METHODS:ZIVIN method was adopted to prepare the model of spinal cord ischemia-reperfusion injury. The rabbit models were randomly divided into model group, sham operation group, and hydrogen-rich saline group.
RESULTS AND CONCLUSION:Improved Tarlov scores for the evaluation of motor function were significantly increased in hydrogen-rich saline group compared with the model group at 6, 12, 24, 72 hours after reperfusion (P<0.01). The contents of malondialdehyde were significantly lower (P<0.05), while catalase activity was significantly higher (P<0.05) in hydrogen-rich saline group than that in model group at 72 hours after reperfusion. Hematoxylin-eosin staining revealed that, spinal cord anterior-horn motor neurons maintained intact structure in sham operation group;more necrotic spinal cord anterior-horn motor neurons were found in model group, and granular-vacuolar degeneration occurred in the endochylema. In hydrogen-rich saline group, the structure of spinal cord anterior-horn motor neurons was basical y intact, only a smal amount of spinal cord anterior-horn motor neurons appeared vacuolar degeneration. TUNEL staining showed no apoptotic spinal cord anterior-horn motor neurons in sham operation group. Many inflammatory cel s and apoptotic neurons were found in model group. There were few inflammatory cel s and apoptotic neurons in hydrogen-rich saline group. Hydrogen-rich saline can prevent the apoptosis of spinal cord anterior-horn motor neurons in rabbits with spinal cord ischemia-reperfusion injury, and the underlying mechanism is associated with antioxidative effect.

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%.
