Objective To explore the role of defoamer enema combined with bellym assage on the colonic preparation in elderly patients with constipation. Methods One hundred patients were divided into two groups by random number table method, the experimental group and the control group with 50 cases each. Patients in the control group were told to drink polyethyleneglycolelectrolytesolution 3000 ml. Patients in the experimental group were told to drink polyethyleneglycolelectrolytesolution 2000 ml. After medicinepre paration, the patients of experimental group were given defoamer enema. After that, they were undertaken counterclockwise massage for10 mins, then massageing clockwise until defecation. Results 14 patients with oral catharsis drugs failed to give up check, 46 cases of intervention group and 40 cases of control group finally complete intestinal preparation and colonoscopy. Intervention group patients after bowel preparation before the incidence of abdominal distension, abdominal pain were 6.52% (3/46), 8.70%(4/46), lower than the control group 65.00% (26/40), 25.00% (10/40), the difference was statistically significant (χ2= 32.74, 4.17, P< 0.05). Percent of pass was 65.22%(30/46) for intestinal preparation intervention group, significantly higher than the control group 35.00% (14/40), the difference was statistically significant (χ2= 7.82, P< 0.05). Intervention group intestinal cleanliness ratings of Ottawa total score was 4.00 (4.00), which was lower than the control group 7.00 (4.50), the difference was statistically significant (Z= 3.80, P< 0.05). Endoscopic check process, the intervention group arrived at the terminal ileum and mirror back time were 7.00 (3.00) and 9.00 (1.00) min, were less than 9.00(6.50) and 10.50 (3.00) min in the control group, the difference was statistically significant (Z= 2.09, 4.53, P< 0.05). Intervention group of colons polyps detection rate was 67.39% (31/46), higher than that of control group 30.00% (12/40), the difference was statistically significant (χ2 = 11.97, P< 0.05). Conclusions The bowel preparation with defoamer enema will enhance the intestinal tract cleaness and the detection rate of polyps in elderly patients with constipation.

Objective:To evaluate one-year efficacy and safety of sirolimus-eluting stent with biodegradable polymer coating (EXCEL stent) in treating patients with coronary artery disease. Methods:One hundred consecutive hospitalized patients with coronary artery diseases exclusively treated with EXCEL stents were prospectively enrolled.After undergoing porcutaneous coronary intervention (PCI) all patients received dual anti-platelet therapy with clopidogrel and aspirin for 6 months and followed by aspirin alone.The primary end point was major adverse cardiac events(MACE) at 12 months.The secondary end points included binary in-stent restenosis rate(ISR)measured by quantitative coronary angiography (QCA) analysis at mean 8 months post the index PCI procedure,and MACE at 30 days and 6 months. Results:All patients were successfully treated with EXCEL stents during PCI procedure.Among all 153 target lesions,127 lesions were type B2/C complex lesions (83.0%).The mean length and diameter of the target lesions were 29.42?15.90 mm and 3.17?0.53 mm,respectively.A total of 211 EXCEL stents were implanted with average stent number of 2.02?1.53 per patient.The mean stent length and diameter were 35.34?17.35 mm and 3.23?0.46 mm,respectively.Four patients (4.0%) reached the primary end point at 12 months,which were 4 target lesion re-PCI due to ISR.No death,MI,or in-stent thrombosis occurred during the 6-month aspirin treatment alone after comleting 6-month dual anti-platelet therapy.QCA analysis of 112 le- sions of 75 patients showed 3.6% (4/112) of in-stent restenosis and 5.4% (6/112) of in-segment restenosis. Conclusions:The initial registry study showed that comparison with the published data from previous pivotal studies of others drug-eluting stents,the EXCEL stent revealed similarly incidence of 12-month ISR and/or MACE for the real world patients with coronary artery disease.The anti-platelet regimen of 6-month clopidogrel treatment after EXCEL implantation was safe.This con- clusion requires further investigation by large scale,multi-center,and longer-term follow-up clinical trials.

Objective To observe the efficacy of ealcitonin and bisphosphonates on renal osteopathy of maintenance hemodialysis (MHD)patients. Methods Forty-three MHD patients were raindomly divided into two groups: A group and B group. All the patients were routinely received oral calcium carbonate 1.0 g tid and calcitriol 0.25 μg qd. Calcitonin (20U) hypodermic injection was given three times a week additionally during hemodialysis in A group. Patients in B group received bisphosphonates 70 mg once a week based on the therapy of A group. Serum levels of intact parathyroid hormone (iPTH), calcium, phosphorus, alkaline phosphatase (AKP), bone mass density (BMD) of lumbar spine and femoral neck, and the degree of bone ache (visual analogue scale, VAS) were assessed before the therapy and 3, 6 and 12 months after treatment. The adverse reactions were recorded during treatment. Results The levels of AKP and iPTH in both two groups decreased significantly after treatment. The above values of pre-treatment and 12 months after treatment were as follows: AKP(U/L)of A group 244.05±41.99 and 148.35±27.71,of B group 245.60±40.86 and 143.40±28.03;PTH(ng/L) of A group 697.5±119.7 and 267.4±45.9,of B group 708.2±120.3 and 277.6±41.9 (all P<0.05). While the levels of calcium and phosphorus did not change obviously during treatment (P>0.05). BMD was not improved at 3, 6 mouths and became better at 12 mouths after treatment. As compared to pre-treatment, BMD of lumbar spine(g/cm2) in A group was 1.062±0.223 vs 1.202±0.251 ,in B group 1.033±0.152 vs 1.189±0.225; BMD of femoral neck (g/cm2)in A group was 0.993±0.108 vs 1.067±0.095,in B group 0.947±0.083 vs 1.018 ±0.217 (all P<0.05). The scores of VAS also decreased significantly at 3, 6, 12 months after treatment(P<0.05). No severe adverse reaction was found during the treatment. Conclusions Utilization of calcitonin and combination with bisphosphonates during bemodialysis can effectively preserve the BMD and prevent bone loss in MHD patients and is well tolerated. No significant difference of therapeutic effect is observed between using ealcitonin or combination with bisphosphonates.

0.05).The difference between the two groups was not significant(P=0.834).Conclusion:The incidence of drug fever induced by the use of puerarin sterile injection powder was not more than that of the controlled group.

Objective To investigate the accuracy of three-dimensional ultrasound volumetric measurements for children's bladder. Methods The bladder volumes of 238 children aged 9 months to 16 years (male:106;female:132) in Shenzhen Children's Hospital underwent real-time three-dimensional ultrasound for volume measurements. These cases were divided into six groups according to the body surface area:(0.36~0.60) m2 (27 cases), (0.61~0.78) m2 (66 cases), (0.79~0.89) m2 (52 cases), (0.90~1.05) m2 (33 cases), (1.06~1.20) m2 (30 cases) and (1.21~1.78) m2 (30 cases). The bladder volume measured by GE Voluson E8 and Philips iU22 were compared with the actual volumes of discharge urine. The relation between bladder volume measurements and the actual volume of discharge urine was analyzed. Results Children's bladder volume increasesd with the body surface area (F=33.53, P<0.05) and showed positive correlations with the body surface area (r=0.679, P <0.05). Compared with the actual volume of discharge urine, each group's bladder volume measurements obtained by three-dimensional ultrasound were lower and the results were as follows:[(47.80±30.33) ml vs (82.24±49.63) ml, (77.20±39.72) ml vs (139.98±79.03) ml, (95.96±50.79) ml vs (175.96±101.70) ml, (117.46±54.17) ml vs (206.62±86.22) ml, (145.53±73.60) ml vs (253.33±135.09) ml and (220.27±110.34) ml vs (327.42±165.45) ml]. The differences between children's bladder volume measurements and the actual volume of discharge urine were statistically significant (t=3.19, 5.53, 5.08, 4.49, 3.84 and 3.00, all P <0.05), but children's bladder volume showed positive correlations with the actual urine volume (r=0.881, P<0.05). The bladder volume measurements by spheroid formula based on two-dimensional ultrasound are lower than the actual volume of discharge urine, and the results were as follows:[(50.38±36.94) ml vs (82.24±49.63) ml, (86.77±62.34) ml vs (139.98±79.03) ml, (102.69±60.21) ml vs (175.96±101.70) ml, (107.94±55.14) ml vs (206.62±86.22) ml, (145.31±66.01) ml vs (253.33±135.09) ml and (222.77±132.59) ml vs (327.42±165.45) ml]. The differences were statistically significant (t=3.03, 4.01, 4.47, 4.95, 3.94 and 2.75, all P <0.05), but children's bladder volume showed positive correlations with actual urine volume (r=0.326, P <0.05). Conclusions Three-dimensional ultrasound volumetric measurements for children's bladder is feasible and in clinical application, the factors of children's growth should be take into account. Combing regression equation, children's bladder volume can be more accurately quantified.

Objective To observe the protein degredation of empty puparium cases ofC. megacephala after weathering and to explore its practical significance on postmortem interval estimation in forensic science. MethodsThe standardized feeding was used inC. megacephala, and the empty puparium cases were collected and put into the forest. They were taken back 5 days, and 10 days later, respectively. The spectra were collected and preprocessed, and then the absorption peaks of amides were read, and curve fitting was performed in the average spectra of each group. The statistical analysis was performed by SPSS 19.0.Results Compared to control group, ifve days post weathering, the position of amideⅠabsorption peak showed blue shift, but the amideⅡabsorption peak showed no shift, moreover, none of the amide absorption peaks showed changes inpeak intensity. For the secondary structures, α-helix decreased and β-sheet increased slightly, however, β-turn did not change; Ten days post weathering, the positions of both amideⅠandⅡabsorption peaks showed blue shift, and an obviousshoulder peak appeared in amide I absorption peak. Meanwhile, both of amideⅠandⅡabsorption peaks showed decreased in peak intensity. Moreover, for the secondary structures, α-helix and β-sheet showed the same tendency as in the 5th day group, except for the β-turn increased dramaticlly.Conclusion The spectra of the empty puparium cases of C. megacephala showed that the absorption peaks of amideⅠandⅡpresented certain characteristic features within ten days post weathering, and estimate relative long-time postmortem interval.

PurposeIt has been reported that women have higher incidence of Modic changes than men and it may be related to the change of female hormone levels during menopause which leads to osteoporosis and other factors. This paper investigated the relationship between vertebral bone mineral density (BMD) of menopausal female suffering from chronic low pain and lumbar vertebral Modic changes on MRI, to explore the effect of vertebral bone mineral density upon Modic changes.Materials and Methods A total of 205 menopausal women with chronic low back pain were enrolled and underwent vertebral bone mineral density measurement and lumbar MRI examination. The bone mass of vertebral body and bone imaging data were observed. All patients were divided into three groups according to their level of bone mass: group of normal bone mass: 128 cases; osteopenia group: 58 cases; osteoporosis group: 19 cases. The incidence rate of Modic changes was compared among the three groups and the relationship between bone mineral density and vertebral Modic changes was further analyzed.Results Among 205 patients, 128 were with normal bone mass, 44 had Modic changes (type I: 19 cases; type II: 22 cases; type III: 3 cases) and the incidence rate was 34.4%; osteopenia occurred in 58 patients, among whom 34 had Modic changes (type I: 15 cases; type II: 17 cases; type III: 2 cases), which showed that the rate was 58.6%; 19 patients presented osteoporosis, 15 of whom appeared Modic changes (type I: 6 cases, type II: 7 cases;type III: 2 cases), with the rate of 78.9%. There was statistically signiifcant difference in incidence rate of Modic changes among the three groups (χ2=18.995,P<0.05). Pearson column connection numberC=0.29<0.40. The osteopenia group and osteoporosis group both had higher incidence rates than the group of normal bone mass (χ2=9.636 and 13.680,P<0.01), and the incidence rate showed no difference between the osteopenia group and osteoporosis group (χ2=2.555,P>0.05).Conclusion Lumbar vertebral bone mineral density is correlated to the incidence of vertebral Modic changes in menopausal women with chronic low back pain. With the loss of vertebral bone mass, the incidence of vertebral Modic changes gradually rise. However, the correlation is rather weak; Modic change is a dynamic process, which is also influenced by other factors except vertebral bone mineral density.
