Objective To explore the feasibility and safety of fentanyl, sufentanil or remifentanil combined with target-controlled infusion (TCI) of propofol for sedation in the elderly undergoing colonoscopy. Methods In this prospective randomized study, 60 patients undergoing colonoscopy and propofol TCI were randomly assigned to group F (fentanyl), group S (sufentanil) and group R (remifentanil)(each n=20). Patients in group F received a single bolus of fentanyl, while those in group S and group R received TCI sufentanil and remifentanil separately. The blood pressure, heart rate, blood oxygen content and Bispectral index (BIS) were monitored, and all the complications were recorded. Results All patients were adequately sedated. There were no significant differences in general conditions, hemodynamics changes, sedation depth and adverse event among the three groups (all P＞0.05). Time for recovery was longer in group F [(21.3±4.6) min] than in group S [(19.9±3.3) min] and group R [(15.9±1.8) min, P＜0.05]. Conclusions For the elderly undergoing colonoscopy, sedation with fentanyl, sufentanil or remifentanil combined with propofol TCI is feasible and safe. It is more excellent for the remifentanil group at shorter discharge time.

Objective To investigate the life quality of children with intractable epilepsy and observe the effect of psychological intervention on them.Methods Thirty-nine children with intractable epilepsy,42 children with drug respond epilepsy and 40 healthy children were employed and tested by using of the child self-report scale of quality of life for children with epilepsy.Scores of quality of life were compared among 3 groups.Children with intractable epilepsy were divided randomly into 2 groups:psychological intervention group(19 cases)and non psychological intervention group(20 cases).Only drug treatment was given in non psychological intervention group,drug treatment and psychological intervention were given in psychological intervention group,quality of life was valuated before and 1 month after psychological intervention,then scores of quality of life were compared after and before psychological intervention in psychological intervention group,total scores of quality of life were compared between psychological intervention group after and before psychological intervention and non psychological intervention group.Results Compared with children with drug respond epilepsy and healthy children,the children with intractable epilepsy had lower scores of quality of life(Pa

Background Light leads to the damage of retinal function and structure by promoting the reproduction of radicals and lipid peroxides when retina is exposed to an intense light environment for a long time.It is necessary to study how to protect the retina against light-induced injury in ophthalmology.Objective The aim of this study was to evaluate the effect of anthocyanidin extracts in preventing retinal photic damage.Methods Eighteen clean male Sprague-Dawley (SD) rats were randomly assigned to normal saline group,anthocyanidin group and mixed (hydrogen-rich saline (HRS) + anthocyanidin,1:1 in volume) group and 6 rats for each.The electroretinogram (ERG) with international standardized 5 items was recorded from all the rats before experiment.Normal saline,anthocyanidin extracts or mixed solution of 5 ml/kg were intraperitoneally injected in the three groups,respectively,for consecutive 5 days.Then the diffused light with the luminance intensity of (5000±300)lx was used to irradiate the right eyes of the rats for consecutive 3 hours during 19:00 through 7:00 in a device made by our laboratory,and the left eyes were covered at the same time.The ERG was repeatedly recorded 5 days after light irradiation.The rats were sacrificed at the end of the experiment and retinal sections were prepared for the histopathological examination.The functional and structural changes of retinas were compared among the different groups.The use of the rats followed the Statement of ARVO.Results The differences of rat body weight were not statistically significant among the three groups (before experiment:F =0.472,P =0.841 ; after experiment:F =0.658,P=0.762).No any significant difference was found in scotopic 0.01 ERG b wave,scotopic 3.0 ERG a and b waves,scotopic 3.0 oscillatory potentials,photopic 3.0 ERG b wave and 3.0 flicker P1wave between the left eyes and the right eyes in the three groups before experiment (P＞0.05).The amplitudes of various waves of ERG were significantly declined in the right eyes compared with the left eyes (P＜0.05).The mean differential values of scotopic 0.01 ERG b wave,scotopic 3.0 ERG a and b waves,scotopic 3.0 oscillatory potentials were significantly different(F =4.594,P=0.029; F=3.834,P=0.037; F=12.823,P=0.000; F=3.976,P=0.032),but those in photopic 3.0 ERG b wave were not statistically significant (F =1.488,P =0.259).Compared with the normal saline group,the differential values of scotopic 0.01 ERG b wave,scotopic 3.0 ERG a and b waves,scotopic 3.0 oscillatory potentials were all reduced in the anthocyanidin group and mixed group (P ＜ 0.05).The cells of outer nuclear layer were decreased in the right eyes in the three groups compared with the left eyes,especially around the optic nerve head and the upside of the retina,with significant differences between them (P＜0.05),and those in the anthocyanidin group and mixed group were significantly less than normal saline group (P＜0.05).Conclusions Anthocyanidin has a protective effect on light-induced retinal damage of SD rats.The protective effect of anthocyanidin extracts is similar to the integrated effect of the mixed group.

Objective To investigate the clinical efficacy of herbal cake moxibustion in treating chronic renal failure. Methods Sixty CRF patients were randomly allocated to treatment and control groups, 30 cases each. The control group received medication and diet control and the treatment group, herbal cake moxibustion on Shenshu, Pishu or Ganshu in addition. Pre-/post-treatment differences in serum creatinine (Scr), blood urea nitrogen (BUN), endogenous creatinine clearance rate (Ccr) and 24-h urinary protein quantity were observed in the two groups and the clinical therapeutic effects were compared between the two groups after 3 months of treatment.Results The marked efficacy rate and the total efficacy rate were 46.7% and 86.7%, respectively, in the treatment group and 20.0% and 46.6%, respectively, in the control group, and there were statistically significant differences in both between the two groups (P<0.05). There were statistically significant pre-/post-treatment differences in Scr, BUN, Ccr and 24-h urinary protein quantity in the two groups (P<0.05). There were statistically significant post-treatment differences in Scr, BUN and 24-h urinary protein quantity between the treatment and control groups (P<0.05).Conclusion Herbal cake moxibustion is an effective way to treat chronic renal failure.

Objective:To investigate the feasibility of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI)parameters in differentiating musculoskeletal tumors with different behaviours of pathological findings before therapy.Methods:A total of 34 subjects of musculoskeletal tumors were in-volved in this retrospective analysis.DCE-MRI was performed using a fat-saturated 3 D VIBE (volumetric interpolated breath-hold exam)imaging sequence with following parameters:FA,10 degree;TR/TE, 5.6/2.4 ms;slice thickness,4.0 mm with no intersection gap;field of view,310 mm ×213 mm;ma-trix,256 ×178;voxel size,1 .2 mm ×1 .2 mm ×4.0 mm;parallel imaging acceleration factor.The ac-tuation time for the DCE-MRI sequence was 255 s with a temporal resolution of 5 s and 40 image vo-lumes.Using pathological results as a gold standard,tumors were divided into benign,borderline and malignant tumors.Toft’s model was used for calculation of Ktrans (volume transfer constant),Ve (extra-vascular extracellular space distribute volume per unit tissue volume)and Kep(microvascular permeability reflux constant).Those parameters were compared between the lesions and the control tissues using paired t-tests.The one-way analysis of variance was used to assess the difference among benign,border-line and malignant tumors.P values <0.05 difference was statistically significant.Results:Based on the WHO Classification of Tumours of Soft Tissue and Bone(2012)criteria,34 patients were divided into three groups:1 1 for benign tumors,12 for borderline tumors,and 1 1 for malignancies.Compared with control tissues,Ktrans and Kepshowed no difference,but Ve was increased in benign tumors,Kep showed no diffe-rence,butKtransandVewereincreasedinborderlinetumors, Ktrans,KepandVewereincreasedin malignant tumors.Ktrans(P<0.001 )and Kep (P<0.01 )were significantly higher in malignant tumors than in benign and borderline tumors,but did not show any difference between benign tumors and border-line tumors.Ve was significantly higher in malignant tumors than in benign (P<0.05),but did not show any difference between malignant and borderline tumors,benign tumors and borderline tumors (P >0.05 ).Conclusion:DCE-MRI technique is useful to evaluate the pathological behaviour of musculoske-letal tumors.The quantitative analysis of DCE parameters in conjunction with conventional MR images can improve the accuracy of musculoskeletal tumor qualitative analysis.

Objective To study the effect of medically activated charcoal on serum phosphorus level and calcium-phosphorus products in dialysis patients with poorly controlled hyperphosphatemia. Methods A single-center,prospective,self-controlled study was performed.Medically activated charcoal was administered 4.5-7.2 g per day with meals for three months to hemodialysis or peritoneal dialysis patients with hyperphosphatemia after taking calcium-based phosphate binders.The levels of blood phosphorus,calcium,calcium-phosphorus products,intact parathyroid hormone (iPTH),albumin and hemoglobin were detected before and after the treatment.The results were analyzed using paired t-test. Results After 3 months of treatment,the patients' serum phosphorus level was significantly reduced from (2.16 ±0.34) mmol/L (pretreatment) to (1.85±0.30) mmol/L (post-treatment) (P＜0.01).Similarly,the serum calciumphosphorus products were lowered from pre-treatment level of (63.93 ±8.83) mg2/dl2 to posttreatment of (54.12±8.37) mg2/dl2 (P＜0.01).Serum albumin level was slightly reduced from (41.7±2.9) g/L to (40.1±2.2) g/L (P=0.001).In contrast,there were no significant changes in serum calcium and iPTH levels when compared pre- to post-treatment values (P=0.734 and P=0.665,repectively). Conclusion In combination with calcium-based phosphate binder therapy,oral medically activated charcoal can effectively reduce the levels of blood phosphorus and calciumphosphorus products in dialysis patients with refractory hyperphosphatemia.
