Vascular complications after liver transplantation can seriously threaten the survival of patients.In the preoperative assessment and postoperative monitoring of patients' vascular conditions,although the digital subtraction angiography (DSA) is the golden standard for vascular lesion diagnosis,but not the first choice due to traumatic lesions.In some clinical circumstances,DSA can only be used when Doppler ultrasound,spiral CT,and MRI are not applicable,and in most cases DSA is used for treatment rather than diagnosis.This article reviewed the current interventional treatment of vascular complications to stress the important role of DSA in diagnosis and treatment of related complications after liver transplantation.

Objective To investigate the impact on the endothelial cell function and renal blood flow through effective treatment for elderly patients with hypertension. Methods 64 cases of elderly hypertensive patients over 70years old with effective treatment, according to pre-treatment blood pressure, were divided into two groups: hyptension level-2 group(30cases) and hypertension level-3 group(34cases), and 30 cases of elderly people with health physical examination during the same period were setlected as the control group. Endothelial cell function was detected, including the endothelin-1 (ET-1)、 nitrous oxide (NO), thromboxane B2 (TXB2)、 6-keto-prostaglandinF1α (6-K-PDGF1α) in plasma. Renal blood flow was explored by color doppler ultrasonic instrument ,involving peak velocity in systole(PSV) and lowest velocity in end-diastole(EDV) of renal arteries, segmental arteries and interlobar arteries.After indicators had reached the standard 1 month in the hypertension level-2 and hypertension leve1-3 patients with effective antihypertensive therapy, the difference of ET-1, NO, TXB2,6-k-PGF1o and PSV, EDV among the three groups were compared. Results The differences were statistically significant in ET-1, NO, TXB2,6-k-PGF1α, PSV and EDV before treatment among three groups (P ＜ 0.05). After blood pressure treated had reached the standard 1 month,indicators were no statistically meaningful difference among the three groups (P ＞ 0.05). Conclusion After effective clinical treatments, the endothelial cell function and renal blood flow of the elderly hypertensive patients can be improved. At the same time, to delay renal damage in elderly patients with hypertension provide a theoretical basis.

Objective To explore the clinical curative effect of electromyographic biofeedback on pointed foot in children with spastic cerebral palsy. Methods From June, 2014 to December, 2015, 80 children with spastic cerebral palsy and pointed foot were divided into con-ventional group (n=40) and electromyographic biofeedback group (n=40). The conventional group received exercise and massage, while the electromyographic biofeedback group received electromyographic biofeedback in addition. The passive range of motion (PROM) of ankle, the surface electromyographic results and the selective control results were compared before and eight weeks after treatment. Results After treatment, the PROM significantly decreased in both groups (t>9.142, P<0.001);the integrated electromyography and root mean square, and the selective control increased in both groups (t>3.456, Z>3.178, P<0.01), which were better in the electromyographic biofeedback group than in the conventional group (t>3.737, Z=-2.748, P<0.01). Conclusion Electromyographic biofeedback can further improve the foot dor-sal flexure and pointed foot gait of spastic cerebral palsy children.

Objective To explore the effect of oral sensorimotor therapy (OSMT), acupuncture, and low frequency electrical stimulation on salivation in patients with cerebral palsy. Methods From September, 2014 to October, 2015, 80 cerebral palsy patients with salivation were recruited. They were randomly divided into four treatment groups:group A was treated with OSMT, group B was treated with acupunc-ture, group C was treated with frequency electrical stimulation, and group D was treated with acupuncture and low frequency electrical stim-ulation, for eight weeks. Meanwhile, 20 cerebral palsy patients with salivation from outpatients were chosen as control group. Results There was no improvement in the root mean square (RMS) value of surface electromyography (sEMG) after treatment in both the control group and group A (t<1.668, P>0.05), and the RMS value significantly improved in the groups B, C and D (t>8.983, P<0.001). There was no sig-nificant difference in the salivation score and RMS value between the control group and group A (W=389.5, t=2.041, P>0.05), and they was better in the groups B, C and D than in the control group and group A (W>226.0, t>8.534, P<0.01), as well as in group D than in groups B and C (W>306.0, t>3.663, P<0.05). Conclusion Acupuncture and low frequency electrical stimulation could effectively improve salivation in children with cerebral palsy, and their combination was superior to either ones, while OSMT did not show obvious benefit.

OBJECTIVE:To prepare and characterize celecoxib-loaded PLGA nanoparticles. METHODS:Emulsification-solvent evaporation method was adopted to prepare celecoxib-loaded PLGA nanoparticles. With encapsulation efficiency and particle size as the indexes,Plackett-Burman design was preferred to screen the formulation and variables which had a significant effect on the property of nanoparticles. And then Box-Behnken response surface method was used to further optimize selected variables including mass concentration of PLGA,ultrasonic power and ultrasonic time,followed by verification. Malvern particle size analyzer was used to determine the particle size distribution of nanoparticles and Zeta potential of nanoparticle by the optimal formulation technol-ogy,and transmission electron microscope was used to observe the morphology of the nanoparticles,and their drug release in vitro behavior and stability(25,5 ℃)were also observed. RESULTS:The optimal formulation and technology was as follows as PLGA mass concentration of 30.0%,ultrasonic power of 180 W and ultrasonic time of 8 min. For the prepared nanoparticles,encapsula-tion efficiency and particle size were (85.7 ± 4.1)% and (226.1 ± 36.1) nm (n=3) respectively;particle size distribution was (176.2±41.2)nm,polydispersity index was 0.211±0.021,and Zeta potential was(-37.3±1.6)mV. Under the electron micro-scope,the nanoparticles were homogeneous in particle size and distributed spheroidally,with 24 h accumulative release of 52.4%. They were stable within 3 months at 5℃. CONCLUSIONS:Celecoxib-loaded PLGA nanoparticles have been prepared successfully.
