PurposeTo analyze the urinary stone chemical composition using dual source CT (DSCT) dual energy imaging.Materials and MethodsNinety-seven stone samples with known chemical composition were placed in fresh swine kidneys and examined with DSCT dual energy scan, including 55 calcium oxalate stones, 13 hydroxyapatite stones, 9 uric acid stones, 4 cystine stones, 2 struvite stones and 14 mixed stones. The mean attenuation values and dual energy index (DEI) were measured at 80 kV and 140 kV. The stone composition was analyzed to determine the sensitivity, specificity and accuracy.ResultsDual energy analysis showed 59 calcium oxalate stones, 11 hydroxyapatite stones, 9 uric acid stones, 4 cystine stones and 14 mixed stones. 2 hydroxyapatite stones were erroneously marked as calcium oxalate stones and 2 struvite stones as calcium oxalate stones. The accuracy was 95.88% (93/97). The difference CT value at 80 kV and 140 kV and DEI value were statistically significant (P<0.05). The sensitivity for detecting calcium oxalate stones, hydroxyapatite stones, uric acid stones and cysteine stones were 100.00%, 84.60%, 100.00% and 100.00%, respectively; with specificity of 85.70%, 100.00%, 100.00% and 100.00%, respectively; and the accuracy were 95.18%, 97.59%, 100.00% and 100.00%, respectively.ConclusionDSCT dual energy imaging accurately analyzes the chemical composition of urinary stone in vitro, which provides important clinical value in analyzing the urinary stonesin vivo.

Objective To explore the feasibility of laparoscopically intracorporeal delta-shaped anastomosis in distal gastrectomy.Methods 82 consecutive patients with distal gastric cancer received laparoscopic distal gastrectomy, including intracorporeal delta-shaped anastomosis in 39 cases, and handassisted Billroth-Ⅰ anastomosis in 43 cases.The operative time, blood loss, anastomosis time were compared between the two groups.Results There were no differences between the two groups with regard to the operative time [(215 ± 24) min vs.(207 ± 13) min, t =0.406, P ＞ 0.05] and blood loss [(56 ±21)ml vs.(65 ± 26)ml, t =1.441, P ＞ 0.05], although the intracorporeal Delta-shaped anastomosis was more time-consuming than the extracorporeal Billroth-Ⅰ anastomosis [(17 ± 8) min vs.(12 ± 3) min, t =2.529, P ＜ 0.05].Conclusions Demanding expertise and some skills, totally laparoscopic distal gastrectomy with intracorporeal delta-shaped anastomosis is safe and feasible.

OBJECTIVE:To explore the protective effect of L-ornithine-L-aspartate on ischemia-reperfusion injury after partial hepatectomy. METHODS:104 patients underwent partial hepatectomy(vessel occlusion in portal fissure)were randomly divided in-to control group(53 cases)and trial group(51 cases). Control group was given routine liver-protective drugs,and trial group was additionally given L-ornithine-L-aspartate 10 g added into 5%Glucose injection 250 ml intravenously before surgery,for 7 consecu-tive days. The fasting peripheral venous blood was collected in 2 groups on first day before surgery and first,forth and sixth day af-ter surgery to detect liver function;the changes of main aminopherase index(ALT and AST)were compared between 2 groups at different portal fissure vessel occlusion time after surgery. RESULTS:There was no statistical significance in the difference of liver resection range,blood loss,first porta hepatis vessel occlusion time and anesthesia time in both groups during operation (P>0.05). Compared to before surgery,liver function indexes raised to different extent in 2 groups after surgery,with statistical signifi-cance(P<0.05). The levels of AST and ALT in trial group were significantly lower than in control group on first,forth and sixth day after surgery,while albumin level was significantly higher than control group,with statistical significance(P<0.05). Total bili-rubin levels of both groups were approximate basically,there was no statistical significance(P>0.05). Among those patients under-went porta hepatis vessel occlusion with Pringle method and with occlude occlusion time ≥15 min,the AST and ALT level of con-trol group was higher than those of trial group after surgery,but albumin level was below trial group,with statistical significance (P<0.05). CONCLUSIONS:L-ornithine-L-aspartate could improve liver function fast and effectively for partial hepatectomy pa-tients,especially for the patients underwent porta hepatic vessel occlusion with Pringle method for a long time(obvious ischemia-re-perfusion injury).

After 8 weeks of treatment,levels of fasting blood glucose(FBG) and glucagon(Glu) in serum were respectively assayed.Immunohistocmical study was adopted to analyze the expression of glucagon in islet cells.Results Compared with model control group,SMAE of middle and high dose remarkably reduced the level of FBG and Glu(P

Objective To explore the feasibility and cosmetic results of video-assisted subcutaneous mastectomy and immediate reconstruction. Methods Two patients who suffered from breast diseases and need to excise the breasts received a video-assisted total subcutaneous mastectomy and immediate reconstruction in our center. Results Both patients felt satisfied on the cosmetic result. According to the operative experience of these two patents combined with review, the key point of the operation was summarized as follows. The incisions on the anterior axillary line were small and concealing. External retraction method was used to establish the working space. Video-assisted operation was combined with euthyphoria. Blunt dissection was combined with electrical surgery unit and ultrasound knife to isolate the breast skin flap. After breast glandectomy was completed, silica gel prosthesis was put into the interspace behind ectopectoralis. Pressure dressing for 3 weeks was done to prevent the prosthesis upward displacement. Conclusion The video-assisted subcutaneous mastectomy and immediate reconstruction is a safe and feasible operation method with the better cosmetic result.

Dorsal root ganglion (DRG) neurons are primary sensory neurons that conduct neuronal impulses related to pain, touch and temperature senses. To comprehensively identify proteins of plasma membrane (PM) from small amount of dorsal root ganglion (DRG) neurons, a proteomics strategy that utilizes aqueous polymer two-phase partition in combination with differential velocity centrifugation was adopted to enrich the PM, followed by SDS-PAGE, CapLC-MS/MS and bioinformatics analysis. Western blot analysis showed that the concentration of PM in purified plasma membrane(PPM) was 2.3 times higher than that in crude plasma membrane(CPM), 15 times higher than that in whole tissue lysate (WTL). By searching against the rat IPI protein sequence database, a total of 729 non-redundant proteins were identified from the PM preparation, of which 547 had a gene ontology (GO) annotation indicating a cellular component, and 159 (21.8%) were unambiguously identified as PM proteins. A data set of plasma membrane proteins of DRG as well as a tool to study PM proteins were provided in a small amounts of sample.
