Focal intrahepatic strictures (FIHS) refers to local strictures or stenosis of the intrahepatic bile duct induced by various factors. FIHS is easily leading to misdiagnosis and miss diagnosis. At present, most of the techniques or examinations for making position as well as qualitative diagnosis of FIHS have poor sensitivity. Paying more attention to the medical history and combined applications of various inspection methods might help to improve the diagnostic level of FIHS. In terms of treatment, we suggested for patients with suspected malignant strictures or those who were failure of medical treatment, dilation, drainage and pathological diagnosis of FIHS could be conducted by endoscopy before determining the indications and procedures of surgery based on a new anatomy classification system of FIHS.

Objective To evaluate the curative effect and safety of emergency therapeutic endoscopic retrograde cholangiopancreatography (ERCP) and treatment strategy of mobidity and combined diseases for patients aged over 90.Methods The clinical and follow-up data of 116 cases treated by ERCP from January 2002 to December 2006 were analyzed retrospectively.Results The success rate was 97.41% for biliary drainage.The occurrence rate of mobidity was 21.24%(24/113),of which 6 cases of acute pancreatitis (25.00%),2 cases of upper gastrointestinal bleeding (8.33%),12 cases of electrolyte disorders (50.00%),acid-base balance disorders in 4 cases (16.67%).Except the higher incidence of hypokalemia disorders of emergency group than out-patient group (P=0.003),the rest of the mobidity rates were similar in the two groups.The mortality rate and deterioration rate of combined disease between the two groups were also similar.Conclusion Simplify operations,rapid drainage,positive preoperative preparation can effectively reduce the incidence of mobidity and avoid the aggravation of combined diseases.Emergency ERCP for treatment of patients aged over 90 is safe and effective.

Objective To evaluate left ventricular(LV) systolic synchrony and sequence in patients with premature ventricular complexes(PVCs) from right ventricular outflow tract (RVOT).Methods Thirty patients with frequent isolated PVCs from RVOT and 30 healthy subjects as control were included.Speckle tracking imaging (STI) was performed to assess the time-to-peak segmental systolic strain in longit udinal(TsL), circumferential (TsC) and radial (TsR) direction.The standard deviation (SD) of TsL,TsC and TsR of 18 LV segments were calculated respectively.All values of patients with PVCs were recorded during sinus beats(PVC-S) and PVC beats(PVC-V) respectively.LV systolic sequence in PVC-V was analyzed.Results Significant differences were observed in the SD values between the PVC-V and control subjects in three directions,as well as between the PVC-S and control subjects in circumferential and radial direction.In PVC-V significance difference was seen in TsL and TsR from apical to basal level,as well as in TsL and TsC in different walls.Conclusions LV systolic synchrony was demonstrated in patients with PVCs from RVOT during both sinus beats and PVC beats.Systolic sequence in PVC beats from RVOT exhibit certain rules.

Objective To evaluate the left ventricular(LV)global and segmental myocardial systolic function in patients with permanent DDD pacemaker implantation by speckle tracking imaging.Methods Myocardial imaging of LV apical long views and parasternal LV short axis views were performed in 9 patients with right ventricular(RV)septum pacing(RV septum group),15 patients with RV apex pacing(RV apex group)and 13 healthy subjects(control group).Peak systolic longitudinal strain(S_L),peak systolic radial strain(S_R)were measured,and the average of S_L and S_R among LV 18 segments were calculated respectively as corresponding GS_L and GS_R.Results The GS_L[-(18.29±2.67)%]of RV apex group showed significant decrease compared with RV septum group[-(20.54±2.29)%]and control group[-(21.07±2.08)%](P＜0.05),while no significant difference was found between RV septum and control group.The GS_R of the pacing groups were both lower than control group[(36.26±9.37)%in control group,(28.59±6.06)%in RV septum group,(26.85±7.73)%in RV apex group,P＜0.05],but RV apex group showed more decrease trend.The S_L and S_R of the LV myocardial segments close to the pacing sites in both pacing groups showed significant decrease compared with control group,but RV septum group preserved similar LV strain distribution with control group while RV apex group showed abnormal LV strain pattern.Conclusions Speckle tracking imaging is a useful modality to evaluate global and segmental myocardial systolic function of LV with pacing at different right ventricular sites.

Objective To evaluate left ventricular(LV)myocardial contraction patterns and function when pacing in different right ventricular(RV)sites and discuss echocardiogarphic method to evaluate physiologcal pacing mode.Methods This study included 26 patients with paroxysmal supraventricular tachycardia without organic heart disease.Four pacing modes including right atrium pacing(AAI),RV apex pacing(VVI-RVA),RV septal pacing(VVI-IVS)and RV outflow tract pacing(VVI-RVOT)were performed on the patients in a random order after succussful radiofrequency ablation.The parameters measured in each pacing mode included(1)LV systolic function parameters:LV twist angle(Twist),aortic systolic velocity-time integral(VTIAo)and LV global strain(Gε)；(2)LV contracting pattern:segmental peak systolic strain(Sε),the time to peak value(TPε),and the distribution of segmental Sε,TPε in each layer or wall.The relationship between Sε,TPε of each wall was analyzed.[Results]Pacing from RV sites showed lower Twist,VTIAO and Gε than AAI mode.Gε demonstrated significant difference in three RV sites pacing mode(VVI-RVOT＞VVI-IVS＞VVI-RVA,P＜0.05).Compared with the AAI mode,the distribution of segmental Sε,TPε in the each layer or wall alerted significantly in three RV sites pacing mode,especially in VV1-RVA.The distribution pattern was similar in VVI-RVOT and VVI-IVS.Furthermore,the wall Sε collated negtively with wall TPε(r =-0.51,P＜0.001).[Conclusions]Compared with AAI mode,RV pacing,especially the VVI-RVA induced the alternation of LV contraction patterns and reduction of systolic function.Longitudinal strain parameters can be used to assess the myocardial contraction patterns and function in different pacing mode.

Objective To investigate the effect of cluster needling at scalp points plus gavage of modified Buyang Huanwu decoction on NSC differentiation in rats with ischemic stroke of qi deficiency and blood stasis type.Methods A model of qi deficiency and blood stasis syndrome was made using healthy rats. Dil dye was given for pre-labelling after the success of model making. The rats were randomized into groups A, B, C, D, E and F. Group F consisted of 4 rats and each of the other groups, of 12 rats. A rat model of ischemic stroke of qi deficiency and blood stasis type was made by MCAO at 48 hrs after pre-labelling. After the success of model making, group A was the model group, group B was treated by cluster needling at scalp points, group C was treated by an oral gavage of Buyang Huanwu decoction, group D was treated by an oral gavage of modified Buyang Huanwu decoction, group E was treated by cluster needling at scalp points plus an oral gavage of modified Buyang Huanwu decoction and group F was the sham operation group. The rats were sacrificed at various time points respectively and the materials were taken. By nerve function assessment, double immunofluorescence staining and laser scanning confocal microscopy, a comparative study was conducted to investigate the effects of different treatments on NSC differentiation.Results There was a statistically significant difference in the nerve function score between group B, C, D, E or F and group A after one week of treatment (P<0.01), between group B or E and group A after two weeks of treatment (P<0.05,P<0.01) and between group E and group C or D after one and two weeks of treatment (P<0.01,P<0.05). After one and two weeks of treatment, there were statistically significant differences in Brdu﹢/NeuN﹢ cell count, Brdu﹢/GFAP﹢ cell count, Dil﹢/Brdu﹢NeuN﹢ cell count and Dil﹢/Brdu﹢/GFAP﹢ cell count between group B, C, D or E and group A (P<0.01), between group D or E and group B or C (P<0.01) and between groups E and D (P<0.01).Conclusions Various treatments have a promoting effect on nerve stem cell differentiation in the rats. Of various treatments, cluster needling at scalp points plus gavage of modified Buyang Huanwu decoction has the best therapeutic effect.
