Objective To investigate the indications and results of long channel technique with pedicle inner preputial flap urethroplasty for middle hypospadias repair. Methods During September 2007 to April 2010,28 cases of middle hypospadias were include in this study.The average age was 2.0 years (1.5 -6.0 years).The orifice of urethra was opened in the shaft of penis,and the distance between the urethral meatus and the center of glans was 25 mm ( 16 - 37 mm).A pars-meatus skin incision was made,which was dissected deep to the urethral plate.The urethral plate was transected,and a long channel between the urethral plate and the corpora cavernosa was created.The neourethra was made from the inner prepuce,and transposed to the ventral tunnel through a tunnel between buck's fascia and albuginea of ventrolateral corpora cavernosa.The neourethra was anastomosed with the proximal urethra.The buck's and dartos fascia along the skin incision were brought together and sutured individually,covering the proximal neo-urethra and the anastomosis.Induced penile erection confirmed that 13 cases were with mild penile curvature,and the other 15 case were without penile curvature.The average length of the defected urethra and tunnel was 38 mm (30 -42 mm) and 33 mm (26 -38 mm). ResultsSuccess was achieved in all cases without fistula or urethral stricture formation with the average follow-up of 20 months (6 -31 months),and penile curvature was completely corrected.The urethra was opened in the apex of the glans with normal-looking circumcised penis. ConclusionsLong channel technique with pedicle inner preputial flap urethroplasty can provide another option for repairing middle hypospadias without penile curvature or with mild penile curvature,especially for young children and those with small penis.This technique is simple,and the result is satisfied.

In this study, we developed a novel liposome-silica hybrid nano-carrier for tumor combination therapy via oral route, using paclitaxel and cyclosporine as a model drug pair. Optimization of the preparation of the drug-loading formulation and characterization of its physicochemical parameters and drug release profile were performed in vitro. Then in vivo pharmacodynamics and pharmacokinetics studies were performed. The results showed that the obtained formulation has a small particle size (mean diameter of 100.2 +/- 15.2 nm), a homogeneous distribution [the polydispersity index was (0.251 +/- 0.018)] and high encapsulation efficiency (90.15 +/- 2.47) % and (80.64 +/- 3.52) % for paclitaxel and cyclosporine respectively with a mild and easy preparation process. A sequential drug release trend of cyclosporine prior to palictaxel was observed. The liposome-silica hybrid nano-carrier showed good biocompatibility in vivo and co-delivery of cyclosporine and paclitaxel significantly enhanced the oral absorption of paclitaxel with improved anti-tumor efficacy, suggesting a promising approach for multi-drug therapy against tumor and other serious diseases via oral route.

In the present study, a new compound named 17-(6-cinnamamido-hexylamino-)-17-demethoxygeldanamycin (CDG) was obtained by introducing the cinnamic acid (CA) group into the 17-site of geldanamycin (GDM). The anti-cancer effects of CDG in vitro and in vivo were evaluated. MTT assay was used to examine the inhibitory effect of CDG on the proliferation of MCF-7, HepG2, H460 and SW1990 cells. Immunofluorescent staining flow cytometry combined with Annexin V-FITC/PI staining were used to detect apoptotic cells. Transwell assay was used to analyze the effect of CDG on cell invasion and migration ability. Western blotting was used to detect the expression levels of RAF-1, EGFR, AKT, CDK4 and HER-2 of MCF-7, HepG2 and H460 cells. The toxicities of CDG and GDM were evaluated in mice. Using the subcutaneously transplanted MCF-7 xenograft in nude mice, inhibitory effect was evaluated in vivo. The results showed that CDG inhibited the proliferation of cancer cells (IC50: 13.6-67.4 microg.mL-1). After exposure to CDG for 48 h, most cells presented typical morphologic changes of apoptosis such as chromatin condensation or shrunken nucleus. The rates of apoptosis of MCF-7, HepG2, H460 and SW1990 cells incubated with 10 microg.mL-1 CDG were 23.16%, 27.55%, 22.21%, 20.47%, respectively. A dose-dependent reduction of migration of four cell lines was found after exposure to CDG. The decreased levels of RAF-1, EGFR, AKT, CDK4 and HER-2 showed that CDG possessed HSP90 inhibitory effect. The result of animal toxicity test on the mice suggested that CDG had lower toxicity than GDM. Meanwhile, CDG inhibited the growth of MCF-7 xenografts of athymic mice.

Objective To investigate the safety and short-term efficacy for evaluation of the low-profile visualized intraluminal support device (LVIS stents )compression and lantern release shapes for the treatment of wide-necked intracranial aneurysms. Methods From December 2014 to October 2015,15 patients with intracranial wide-neck aneurysm (16 aneurysms)received LVIS stent treatment, whose stent shapes had shortening changes were analyzed retrospectively. Thecompression mode refers to the length of LVIS stent to be shorter for more than 5 mm than the label release value by operation. Thelantern mode refers to the widened diameter of LVIS stent at the neck of aneurysm. The metal coverage rate in the posterior communicating segment of internal carotid artery after stent compression was calculated, and its safety and efficacy were assessed immediately after procedure and at 3 months after procedure. Results (1 )Using LVIS stent-assisted treatment,16 wide-necked aneurysms were treated,including 8 posterior communicating aneurysms,6 ophthalmic aneurysms,one anterior choroidal artery aneurysm and one M2 bifurcation fusiform aneurysm. The aneurysm neck was 1. 8 to 8. 0 mm (mean 3. 9 ± 1. 7 mm). A total of 15 LVIS stents were implanted (one patient with 2 aneurysms were treated with 1 stent). All the stents were released by using compression mode,and 4 of the patients (4 stents)also used the lantern mode at the same time. (2 ) After LVIS stenting,the Raymond grade Ⅰ embolization was in 10 aneurysms (62.5%),the covered branch arteries were patent immediately after procedure. (3)No perioperative technology-related hemorrhagic and ischemic complications occurred. The success rate of stent implantation was 100%(15/15). (4)The metal coverage rate after stent compression in the internal carotid artery posterior communicating segment was 30. 3%-38. 5%(mean 35. 0 ± 2. 8%). (5)After LVIS stent implantation,15 patients were followed up by whole brain DSA for 3 to 5 months (mean 3. 2 ± 0. 5), 14 aneurysms were cured on imaging (Raymond gradeⅠ),and no aneurysm recurred. All branch arteries covered by the stents did not have vascular occlusion. There was no in-stent restenosis or parent artery occlusion. The total disability rate was 6. 7%(1/15),and no patient died. Conclusions LVIS stents can increase aneurysm neck metal coverage rate and short-term cure rate throughcompression andlantern modes,while does not affect the covered branches. Choosing the appropriate cases for thelanternmode may be beneficial to the short-term protection of the vascular branches at the aneurysm necks.

Objective To observe the effect of dihydromyricetin of ampelopsis grossedentata on lipid metabolism and antioxidation in atherosclerosis (AS) rats. Methods Sixty Wistar rats were randomly divided into five groups (n = 12 each):normal control group, model control group, positive control group, high dose dihydromyricetin group (40 mg·kg-1 ) and low dose dihydromyricetin group (10 mg·kg-1 ). Except normal control group, rats in the other groups were injected with a single dose of vitamin D3(600 000 U·kg-1 ) and loaded with high fat diet to establish AS model. Simvastatin (5 mg·kg-1 ) was intragastrically administered to positive control group. High and low dose dihydromyricetin groups received intragastric administration of 40 and 10 mg·kg-1 dihydromyricetin, respectively. Equal volume of purified water was given to normal and model group. After 24 weeks of administration, serum levels of lipids, activities of superoxide-dismutase (SOD) and malonicdialdehyde (MAD) were determined. Results As compared with model control group, triglycerides (TG) of high and low dose dihydromyricetin groups was decreased [(191. 65±101. 10) vs. (111. 10±29. 29) and (120. 55±38. 12) mg·L-1 , respectively], total cholesterol (TC) was decreased [(151. 64±33. 62) vs. (148. 49±30. 14) and (118. 90±27. 38) mg·L-1 ], and high density lipoprotein cholesterol (HDL-C) was increased [(1. 29±0. 68) vs. (2. 10±0. 70) and (1. 62±0. 61) mmol·L-1 ], low density lipoprotein cholesterol (LDL-C) was decreased [(5. 01±1. 33) vs. (3. 97±0. 78) and (4. 28±0. 79) mmol·L-1 ], activity of SOD was increased [(141. 03±42. 52) vs. (187. 97±42. 08) and (150. 99±46. 17) U·mL-1 ], and MDA was decreased [(20. 51±3. 81) vs. (17. 64±1. 54) and (18. 52± 3. 42) nmol·mL-1 ], with significant differences (P<0. 05, P<0. 01). Conclusion Dihydromyricetin can reduce the level of serum lipid, improve antioxidation activity, and has therapeutic effect for atherosclerosis.
