Objective To compare with the different effect of the plasma and serum containing Danshen Injection (DI) on the angiogenesis. Methods The DI-containing plasma and serum at different concentrations and sampled at different time were prepared. The effect of DI-containing plasma and serum on the angiogenesis of chicken chorioallantoic membrane (CAM) was observed by using CAM model. Results The proliferation of vessels in all DI-containing plasms and serum groups and DI group was obvious as compared with that in the group of the blank plasma and serum(P

Objective To investigate the common problems and countermeasure of using ultrasound-guided modified Seldinger technique in peripherally inserted central catheter (PICC) placement Method The clinical data of 140 patients who underwent PICC placement using ultrasound-guided modified Seldinger technique were retrospectively analyzed. Results The success rate of catheterization was 98. 6% among these 140 patients,with 135 (96. 4% ) succeeded after a single attempt and 5 (3. 6% ) after 2 attempts. Besides, 7. 1% (n = 10) had difficulty in inserting the guide wire, 3. 6% (n =5) had difficult catheteration, 2. 1% (n =3) met resistance when inserting catheter into ipsilateral subclavian vein, 2. 1 % (n = 3 ) experienced dystopia of inserting catheter into internal jugulular vein, and 1.4% (n = 2) experienced the bending of PICC in the superior vena cava and axillary vein. All of these problems were handled successfully. Conclusions The common problems of PICC placement include puncture failure, difficulty in inserting guide wire, and difficult catheteration. A good knowledge of these problems will help increase the success rate.

Objective To investigate the feasibility and safety of three-dimensional video-assisted thyroidectomy (3D VAT). Methods During January to April of 2014, 10 cases with unilateral or bilateral thyroid benign diseases , thyroid cancer, or parathyroid lesions were enrolled .The 3D VAT was carried out by using a 10-mm 3D stereoscopic endoscope .Local excision or lobectomy was performed via a 2-4 cm curve skin incision one finger above the sternal notch .In two patients , lobotomy combined with systematic lymphadenectomy was performed when papillary thyroid microcarcinoma was identified during operation . Results All the procedures were accomplished successfully under 3D video-assisted system, without intra-operative abnormal blood loss or conversion to conventional thyroidectomy .The operative time was 30-90 min (61.8 ±22.4 min);the intra-operative blood loss was 1.3-93.0 g (median, 5.2 g).All the patients were followed up for 1-4 months.Neither intra-nor post-operative complications about recurrent laryngeal nerve , superior laryngeal nerve , or parathyroid were observed . Conclusions Preliminary impression emerging from this study seems to suggest that 3D VAT is safe and effective.Compared with 2D surgery, a good perception of depth and easy recognition of anatomic structures are noticeable .

A 35-year-old woman patient,complained of intermittent pain in the left flank for a week.Abdominal ultrasound and computed tomography scan revealed a left renal mass.Nephrectomy was performed,and a final diagnosis of adult Wilms' tumor was made based on histopathology and immunohistology.Chemotherapy was conducted for 4 times with dactinomycin D,vincristine and doxorubicin after surgery.At the time of the last recheck,the patient was alive with no evidence of disease.Adult Wilms' tumor is the exceptional malignant renal tumor.Only 1%-2% of Wilms' tumor is diagnosed in adult patients.Because of unspecific tumor symptoms in adults,the diagnosis is frequently made by histology.The diagnosis of adult Wilms' tumor is difficult to make preoperatively because diagnostic imaging only confirms the presence of a renal mass.Stage and histology are the clinical factors guiding the selection of postsurgical treatment and prognosis.Having retrospected 6 cases of adult Wilms' tumor between 1950 and 2007 and reviewed related reports,we conclude that the proper strategies of adjuvant treatment as applied to childhood Wilms' tumor patients after surgery can conspicuously improve the outcome in adult patients.

This paper introduces the configuration, classification, present status and trend of invasive blood pressure sensor.

Objective To investigate subsequent treatment methods of nipple discharge after fiberoptic ductoscopic examination.Methods Intraductal lesions of 51 patients with nipple discharge were observed and assessed by fiberoptic ductoscopy.After examination,the patients were treated by various methods according to characteristic appearance of lesions under fiberoptic ductoscopy.The type of lesion with nipple discharge was classified as papillary lesions and nonpapillary lesions.And the papillary lesions could be further subdivided into nodular papillary lesions and irregular papillary lesions.There were 29 cases of nodular papillary lesion,23 of which were treated by local resection and 6 of which were given a simple mammectomy.There was 1 case of irregular papillary lesion,which was treated as malignant tumor after the focus was surgically removed and pathologically confirmed as breast cancer.Nonpapillary lesion was observed in 21 cases,18 of which were treated by local irrigation under ductoscopy,and 3 of which were treated as malignant tumor after the abnormal duct with its lobules was pathologically diagnosed as breast cancer.Results The 51 patients were followed with B-ultrasonography or chest roentgenography for 6～21 months(mean,14 months).No recurrence or metastasis was observed.Conclusions The characteristic appearance of lesion with nipple discharge under fiberoptic ductoscopy is an important evidence for choosing treatment method.

Objective To study the effects of Danlong Xingnao Tablet on neuronal apoptosis and expression of TNF-? after focal cerebral ischemia reperfusion in rat hippocampus. Methods The model of middle cerebral arteries occlusion (MCAO) were performed with intraluminal filament blockade. By using in situ terminal deoxynucleotidyl transferase-mediated dUTP-biotor nick end labeling (TUNEL) and immunohistochemistry staining, the number of apoptotic cells and TNF-? positive cells were detected in the sham-operated group, the ischemia reperfusion group, Danlong Xingnao Tablet group and nimodipine group after the middle cerebral arteries of SD rats occluded for 1 h and reperfused for 24 h.Results Compared with the sham operation group, the number of apoptotic cells and TNF-? positive cells of the model group increased significantly (P

Objective To explore the suitable type of macroporous adsorbent resin to purity swertiaman from Swertia pesudochinensis Hara., and determine the parameters and conditions for its purification procedures. Method Purification effect of 8 types of macroporous resins used to purify the Swertia pesudochinensis Hara. were inspected, with the content of swertiaman as index. Result HPD-100 type resin showed better effect than others, it had optimum adsorption and elution parameters with its dynamic saturated adsorption ratio was 70.48 mg/g. After eluted with 2 BV of distilled water, 4 BV 30% ethanol and collected, the content of swertiaman in the spray dried powder was 52.29%. Conclusion HPD-100 types macroporous resin showed a better comprehensive adsorption property and can be used to enrich and purify the swertiaman included active fraction of iridoid glycosides for industrialization.

Objective To compare the therapeutic effects of minimally invasive percutaneous nephrolithotomy(MPCNL) and retroperitoneal laparoscopic ureterolithotomy(RLUL) in the management of impacted upper ureteral calculi.Methods A total of 72 patients with unilateral impacted upper ureteral calculi were treated with MPCNL(n=45) or RLUL(n=27).The operation time,clearance rate of the stone,and the incidence of postoperative hyperpyrexia were statistically analyzed.Results All the operations were completed.As compared to the RLUL group,the MPCNL group had a significant shorter operation time [(43?9) minutes vs(69?17) minutes,t=-11.564,P=0.000].On the day after the operation,both the groups showed a stone clearance rate of 100%.No significant difference was detected in the rate of postoperative hyperpyrexia between the two groups [13.3%(6/45) vs 11.1%(3/27),?2=0.000,P=1.000).The patients were followed up for 1 to 24 months(mean,8 months),none of them developed ureteral stricture or recurrent stones during the period.Conclusion Both MPCNL and RLUL are safe,effective,and feasible for impacted upper ureteral calculi.
