Objective To analyze multislice CT (MSCT) multiphase multiphase enhancement scanning in the atypical hemangiomas. Methods During February 2013 from January 2014, chosing125 cases of patients with atypical hemangiomas in our hospital were retrospectively analyzed. Results There was a total of 240 lesions in 125 patients, multiple (2 or higher) in a total of 70 cases, 55 cases of single. A total of 170 were located in the right lobe, 70 were located in the left lobe, lesions was 0.8 to 4.5 cm in diameter, the average was (2.53±0.21) cm. A total of 205 lesions were circular, a total of 35 as lobulated or irregular. CT scan, a total of 155 were low density, 85 in equal density. A total of 120 state clearly, realm for part of the fuzzy and parts out of a total of 35, 85 was fuzzy. A total of 45 lesions density uneven, a total of 195 was lesions density uniformity. In 240 intrahepatic lesions, a total of 145 lesions present performance1, 80 lesions belong to 2 kinds of forms, 15 lesions characterized by 3 kinds of forms. Conclusion Although a few hemangiomas reinforcement is not typical, by the mutiperiodic enhanced MSCT scanning remain their respective characteristics, in identification of its pathological changes has important diagnostic value.

Objective To assess the efficacy and safety of flexible cystoscope conducted holmium laser lithotripsy via percutaneous nephrostomy in the treatment of upper urinary tract calculi.Methods The flexible cystoscope conducted holmium laser lithotripsy via percutaneous nephrostomy was performed on 26 patients from Jul 2005 to Jan 2007. Among these patients, 8 had bilateral renal calculi and ureteral calculi, 5 had multiple renal calculi, 4 had renal calyx calculi and 9 had ureteral calculi. The average diameter of the calculus was 2.2 cm (range from 1.0-3.2 cm). Four patients had mild hydronephrosis, others had moderate or severe hydronephrosis. Insufficient renal function was noted in 13 cases. The procedure was performed via a single tract through the middle calyx under the ultrasonic guidance in all cases.Results Twenty-two cases achieved stone free at primary procedure, secondary procedure was needed in 4 cases. A 18 F tract was used in 18 cases and 24 F tract was used in the left 8 cases. The average operation time was 72 min, stone-free rate was 96.2%(25/26),and there was no blood transfusion. One patient had fever after the procedure and recovered 2 days after the administration of antibiotics. No other complication was recorded. In an average 11 month follow-up in 22 patients, hydronephrosis reduction was significant observed by ultrasound scan. No calculus relapse was found.Conclusions Flexible cystoscope conducted holmium laser lithotripsy via percutaneous nephrostomy is an effective and minimally invasive technique for the treatment of upper urinary tract calculus. It has the advantages in dealing with the calyx and ureteral calculus located in the proximal or middle segment as well.

Objective To evaluate the efficacy and safety of percutaneous nephrolithotomy (PCNL)guided by ultrasonography through upper pole access. Methods From October 2007 to October 2009, 42 patients with upper urinary tract calculi underwent PCNL through upper pole access.Among these cases, there were 10 cases of staghorn calculi, 22 cases of renal pelvis calculi, 7 cases of the upper calyx calculi, 3 cases of the lower calyx calculi, 4 cases combined with ureter calculi and 2 cases combined with ureteropelvic junction obstruction. The stone measured from 2.0 to 6.5 cm (average: 3.4 cm) in length. Working tunnels (F16-F26) were established through the 10th or llth intercostals. Pneumatic or holmium laser lithotripsy was used to disintegrate and remove stones by nephroscopy or ureteroscopy. Clinical data including operation time, complications and stone free rate were analyzed retrospectively. Results All the operations were completed in one session, single tract was used in 36 cases(85.7%), double tracts were used in the other 6 cases(14.3%). The stonefree rate after one session was 88.1% (37/42), 3 cases(7.1%) received a second-session PCNL, 2 cases (4.8%)underwent ESWL after operation. The mean operative time was 65 min(30- 140 min).Postoperative surgery-related infection rate was 9. 5% (4/42). One patient (2. 4%)required blood transfusion. Perforation of the pelvis occurred in 1 patient(2.4 %). No pleural or important organ injury occurred. Conclusion The upper pole access for PCNL can be convenient to remove stones,this method is a highly efficient and safe technique.

Objective To evaluate the feasibility and clinical efficacy of laparoscopic nephron-sparing surgery without renal wound suturing.Methods From December 2012 to February 2014,9 patients (4 male,5 female) with renal tumor underwent laparoscopic nephron-sparing surgery without suturing in our hospital.The mean age in those patients was 56 years (range 42-72 years).The mass size ranged from 1.1to 3.8 cm (mean 2.4 cm).The location of tumor included 2 in left kidney,7 in right kidney.Meanwhile,6 tumors were found in the middle part of kidney,2 tumors were demonstrated in the lower part of kidney,and 1 tumor located in the upper part of kidney.The imaging examination confirmed that all tumors protruded the renal surface and infiltrated into the renal parenchyma about 0.1-1.2 cm,which could be defined as the peripheral renal tumor without the invasion of collective system.The retroperitoneal approach was used in all patients with 3 trocars.During the operation,the renal artery was exposed and fats surrounding or on the surface of the tumor were resected.The renal artery was occluded.Tumor excision was then performed using scissors.An incision was made at the point 0.5 cm away from the margin of the tumor,extending deeply to completely cut the tumor.Meanwhile,bleeding was controlled with bipolar diathermy.Then,the clamping of the renal artery was removed and the retroperitoneal pressure was reduced in order to check the site of bleeding.If the bleeding occurred severely,the kidney wound was sutured with 2-0 absorbable sutures.Otherwise,the coagulative glue was sprayed on the wound surface.Results In all the patients,the procedures were done without conversion to open surgeries.The renal wound suturing appeared in one case because the tumor infiltrated into the deep of the kidney and the bleeding could not be completely controlled by bipolar diathermy.Eight of 9 cases were successfully performed without suturing.The mean time of renal artery occlusion was 8 min (range 3-18 min).In our patients,the mean operation time was 120 min (90-180 min),and the mean blood loss was 60 ml (10-200 ml).None of the patients received blood transfusion during the surgery.The mean postoperative hospital stay was 7 days (5-9 days).No complications,such as urine leakage,bleeding occurred after the operation.All the patients were followed up with no recurrence of tumor.Conclusions Laparoscopic nephron-sparing surgery without renal wound suturing is feasible and safe for patients with the small and the depth of infiltration less than 0.5 cm tumor in the kidney.

Growth year is one of the important factors for the quality of mountain cultivated ginseng (MCG). For age differentiation of MCG, rhizome extracts of ginseng aged from 11 to 15 years were analyzed using a non-targeted approach with ultra-performance liquid chromatography/quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS)-based on plant metabolomics technique. Multivariate statistical methods such as principal component analysis (PCA) and orthogonal partial least squared discrimination analysis (OPLS-DA) were used to compare the derived patterns among the samples. The results showed that the chemical constituents of MCG rhizome extracts of ginseng aged from 11 to 15 years were different. The data set was subsequently applied to metabolite selection by variable importance in the projection (VIP) for sophisticated classification with the optimal number of metabolites. The OPLS-DA model of MCG has a high interpretability and predictive capability, which established by selecting metabolites of MCG aged from 11 to 15 years. By this approach, MCG samples aged from 11 to 15 years, which are the most in demand in the Chinese ginseng market, can be precisely differentiated on the basis of selected metabolites. This proposed analytical method is fast, accurate, and reliable for discriminating the growth year of MCG. Moreover, this study supplies a new method for the age discrimination of other Chinese medicinal materials.
