OBJECTIVE:To observe the clinical efficacy and safety of prucalopride in the treatment of functional constipation (FC). METHODS:In prospective self-controlled study,87 female patients with FC were selected and given prucalopride 2 mg,1 time per day. The total course was four weeks. The defecate frequency,stool property and constipation symptom grade were ob-served before and after treatment. Related adverse drug reaction were observed during treatment. RESULTS:During the period of treatment,the defecate frequency was gradually increased,the stool property was gradually improved,and the constipation symp-tom grade of the patients was also improved. The difference had statistical significance before and after treatment(P<0.01). No sig-nificant adverse drug reaction was found during the study. CONCLUSIONS:Prucalopride is a safe and effective treatment for pa-tients with FC.

Methods:Mice were given maximal dose, 26g?kg -1 of body weight, XND Ig once; Divided 53 mice into five groups, they were administered XND tab.(3g?kg -1 ), RSC(1.25g?kg -1 ), CDDP(1.25g?kg -1 ), XSTL(2.5g?kg -1 ), and NS once daily for 7 days, repectively; 1h after treatment the seventh day, the animals of groups iv. were given collagen adr by producing whole organism thrombus, observing the mortality, They were determined coagulation time with the blood capillaries and the number of writhings per mouse was recorded in order to determine pain. Results:Maximal tolerance (Ig) is 26g?kg -1 , 886.7 times the dose of clinical application apart from XSTL, three kinds of drug showed the avidence of antithrombotic effect ( P

Objective To evaluate the effect on the corneal endothelial cell after phacoemulsification using the microburst mode with high vacuum. Design Prospective,observational case series. Participants 98 age-related cataract patients (120 eyes). Metheds All patients having phacoemulsification with the Alcon Legacy 20000 Everest software were assigned to 1 of 3 groups (the burst mode group,the pulse mode group and the continuous mode group). Main Outcome Measures Actual power,effect phaco time,visual acuity,corneal edema,and corneal endothelial cell loss. Results The mean actual power of the burst group was statistically lower than those of the other two groups,the effect phaco time of the burst group was statistically shorter than those of the other two groups. The corneal edema and the endothelial cell loss of the burst group were less than those of the other two groups. Conclusion The microburst mode with high vacuum increased efficiency of ultrasound power and decreased the loss of endothelial cell. (Ophthalmol CHN,2006,15: 201-205)

1.5mm)and received CTR scleral fixation.Visual acuity before and after surgery were examined.IOL tilt and decentration were measured with PentaCam system.Complications were also recorded.Main Outcome Measures Postoperative visual improvement,IOL position and complications.Results At the last postoperative examination,best corrected visual acuities of all eyes were increased(P=0.000).The mean IOL tilt was 4.33?2.96?before and 4.11?2.05?after CTR fixation,the mean decentration was 2.56?0.90mm before and 1.19?0.71mm after.No significant differences were found in IOL tilt before and after CTR fixation(P=0.844),but there were significant differences in IOL decentration(P=0.009).Posterior capsular opacification was found in 8 eyes(20.5%)during the follow-up period,and 2 eyes(5.1%)received Nd:YAG posterior capsulotomy.1 eye received IOL scleral fixation because of capsule rupture during CTR implantation.2 eyes suffered from temporary IOP elevation after surgery.No other severe complications occurred.Conclusions Phacoemulsification with CTR and IOL implantation is effective and safe for congenital subluxated lenses.CTR scleral fixation is a necessary supplement for severely subluxated lenses and progressive cases.

Objective To discuss the influence of two recombinant hemoglobin (rHb1.1 and rHb2.0) and human serum albumin (HSA) on oxygen supply and demand balance in rat with coronary heart disease (CHD). Methods Male Wistar rats were randomly divided into normal control group, CHD model group, HSA treatment group, rHb1.1 treatment group and rHb2.0 treatment group, 20 rats in each group. Rat model of CHD was established by high fat diet combined with pituitrin injection. The mean arterial pressure (MAP) decreased to 40 mmHg (1 mmHg = 0.133 kPa) after femoral arterial blood was drawn from the femoral arteries, and the rats were resuscitated with 13.4% HSA, rHb1.1 and rHb2.0, respectively, at the rate of 60 mL·kg-1·h-1 (20 mL/kg). The changes of electrocardiogram (ECG) ST-segment were calculated before model reproduction and at 12 hours after the last time injection of pituitrin. MAP, heart rate (HR), superior mesenteric artery blood flow (QSMA) and arterial blood gas analysis were recorded at 0, 30, 60, 90 and 120 minutes after the administration. The blood was collected after 12-hour fasting, and serum total cholesterol (TC) and triglyceride (TG) were determined by enzymatic method. The pathological changes in cardiac tissue were observed with light microscope. Results Compared with the normal control group, the changes of ECG ST-segment and TC, TG of model group were significantly increased. Compared with the model group, rHb can significantly reduce the value of ST segment changes, and HSA has no such effect; rHb short-term infusion has no significant effect on blood lipids, but can reduce myocardial pathological changes. Compared with the normal control group, the MAP of the model group decreased significantly, the HR was increased, the QSMA was slowed down, the pH value, the residual alkali (BE), the arterial carbon dioxide partial pressure (PaCO2) and HCO3- were decreased significantly. MAP in rHb1.1 group and rHb2.0 group were significantly higher than those in HSA group. Values of MAP were significantly higher in rHb2.0 group than those in rHb1.1 group at 90 minutes and 120 minutes (mmHg: 80.9±3.3 vs. 69.4±4.9, 79.2±4.0 vs. 69.1±3.7, both P < 0.05). The HR of HSA, rHb1.1 and rHb2.0 decreased to normal in 30 minutes after administration, significantly lower than those in the model group (bpm: 534±46, 518±28, 526±37 vs. 609±52, all P < 0.05). In the rHb2.0 group, the QSMA increased significantly at 60, 90 and 120 minutes compared with the model group (qv·mL-1·min-1: 5.6±0.4 vs. 3.9±0.6, 6.2±0.6 vs. 4.1±0.4, 6.9±0.7 vs. 4.0±0.3, all P < 0.05), but there was no significant difference between the HSA group and the rHb1.1 group. The pH, BE, PaCO2 did not return to the normal level after administration of HSA; pH, PaCO2 and HCO3- in the rHb1.1 group returned to normal level at 60 minutes after administration, and BE returned to normal level at 90 minutes after administration. Each index in rHb2.0 group can restore to normal levels 30 minutes ahead of. Conclusion Recombinant hemoglobin can significantly improve the oxygen supply and demand balance of rats with CHD model, can quickly and effectively correct the hypoxic state of blood metabolic acidosis, and rHb2.0 has better effect than rHb1.1.

Root canal biofilm is frequently detected in the canal wall of infected root canal and the root canal with failed root canal therapy. Due to its special structure and diverse composition, root canal biofilm has the ability of the drug tolerance and antiimmunity, which lead to apical periodontitis. This review summarizes the features of the root canal biofilm and latest clinical methods to remove it.

Objective:To evaluate the application of puncturing the umbilical cord under the ultrasound guidance in prenatal diagnosis,clinical high risk factors of fetal chromosomal abnormalities were discussed.Methods:283 pregnant women who had the percutaneous umbilical cord blood sampling were recruited and the karyotyping was done.The detection rate of chromosomal abnormalities and correlate factors in different subgroups of prenatal diagnosis were analyzed.Results:The success rate of puncture was 100%.Major complications were bleeing at the puncture site(33 cases,11.67%)and fetal heart brachycadia(5 cases,1.77%).25 chromosomal abnormalities were found and the detection rate was 8.83%.There was significant correlation between the couple's chromosomal abnormalities and the fetal's(r=22.348,P=0.000).Conclusions:The ultrasound guided percutaneous umbilical cord blood sampling proves to be valid in the prenatal diagnosis,especially when couples have chromosomal abnormalities.
