Carotid artery stenting is one of the main methods for the treatment of carotid artery stenosis.However,as a severe complication after stenting,restenosis has restricted its clinical application to a certain extent.At present,the pathogenesis of restenosis after stenting is not very clear.More and more studies have shown that it may be associated with vascular endothelial injury,platelet aggregation,and inflammatory response.This article reviews the pathophysiological mechanisms of restenosis alter stenting.

[Purpose] To observe the clinical effects, relapse rate and security of treating the verruca plana with the cure warts capsules combined with Burt's res-q ointment. [Methods] Eighty patients with verruca plana were randomly divided into two groups. Forty patients in the combination group received cure warts capsules combined with Burt's res-q ointment; others in the control group received 0.1% al-transretinoic acid cream only. The courses of treatment of two groups was four weeks, then observe the number of verruca plana and bad reaction after the treatment, and record four weeks fol ow-up observation of relapse. [Results] The effective rate of treatment group was 92.50%which was significantly higher than the control group that the effective rate was 50.00% , and the former’s relapse rate was 3.40% which was significantly lower than that in the group which was 44.40% , the above showed significant difference(P<0.05).There was no significant side effects in the two groups. [Conclusion] Cure warts capsules combined with Burt's res-q ointment had better effect, low relapse rate and high safety.

In the complications of dental implant treatment, the mechanical complications, such as central screw breakage, are often complex and serious. This article analyzes factors that affect the loosening of the central screw. Understanding relevant risk factors can prompt doctors to take corresponding strategies to reduce the possibility of complications in clinical operations. After encountering broken cases, this paper also gives some ideas and methods of treatment, and finally summarizes clinical suggestions for preventing the central screw fracture.

Objective: To observe the pathophysiological changes of dogs with open abdominal injury and seawater immersion-induced acute heart failure. Methods: Adult mongrel dogs were randomly divided into open abdominal injury+ seawater immersion group (group A, n=8) and simple open abdominal injury group (group B, n=8). The cardiac rhythm, heart rate, systolic pressure, diastolic pressure, mean arterial pressure, pulmonary wedge pressure, central venous pressure, cardiac output, heart index, rennin, B-type brain natriuretic peptide (BNP), other relevant parameters and death rate were observed before and after open abdominal injury, during 2h seawater immersion, and at different time points after getting out of the water. The left ventiricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), stroke volumes (SV), and left ventricular ejection fraction (LVEF) were measured before and 4 h after injury by ultrasonic cardiogram. Results: The mean arterial pressure decreased significantly in group A from 5 min after injury to the end of the ovservation (P<0.05, P<0.01), and that of group B had no measurable changes. The pulmonary capillary wedge pressure (PAWP) increased significantly; the central venous pressure, cardiac output, and cardiac index decreased gradually, and continued to decrease after putting out of water,which were significantly different from those of group B(P<0.05, P<0.01). Group B had no measurable changes in PAWP, central venous pressure, cardiac output, and cardiac index before and after abdominal injury. The blood rennin and BNP levels were significantly increased in group A (P<0.05, P<0.01) and had no significant changes in group B. Conclusion: Prominent pathophysiological changes occur in rats with open abdominal injury and seawater immersion-induced acute heart failure.

ObjectiveTo observe the effect of Muscle Stimulating Instrument in enforcing the strength of weaken muscles after selective posterior rhizotomy (SPR). MethodsA group of 27 patients with spastic cerebral palsy aging from 3 to 10 years at the average of 5.7 years were treated with the instrument after SPR. A control group of 36 cases was adopted. Muscle strength, gait and motor function amelioration were compared between two groups. ResultsResults of treatment group in both muscle strength and motor function are better than those of the control group (P<0.05).ConclusionsMuscle stimulating instrument is effective to tone up the muscles which patients felt weak after SPR, and to accelerate the course of rehabilitation.

Laser peripheral iridotomy ( LPI) is one of the main therapy for glaucoma due to its reliable efficacy of widening peripheral angle and therefore decreasing intraocular pressure by partially relieving pupillary block. The parameters of the anterior chamber angle following the LPI are the main evaluation indexes. At present,the detecting and diagnosis technique for the anterior chamber angle is deeply advancing, including gonioscopy, ultrasound biomicroscopy, anterior segment optical coherence tomography and Pentacam. These methods offer some useful parameters and also present with some limits in the application respectively in the evaluation of anterior chamber and angle structure. This review focuses on the application of Methods mentioned above and morphologic changes of anterior chamber and angle structure following the LPI.

[Objective]To investigate the clinical value of OCM approach of minimally invasive total hip arthroplasty(MIS-THA).[Method]From February 2005 to December 2006,18 cases of MIS-THA were performed with OCM approach technique.The mini-incision through the intermuscular interval provided a good exposure for total hip replacement,preserved muscle integrity and kept the posterior capsule intact.A two-stage osteotomy of femoral neck was conducted.Specialized acetabular and femoral instruments were applied to fix the prosthesis.[Result]The average length of skin incision was 9.2 cm,the blood loss and drainage were 230 ml and 90 ml,respectively.At 6 months after operation,the mean Harris scores of hip increased from 46.2 to 87.1 for all cases.One case of femoral fracture around prosthesis and one of excessive anteversion were observed.[Conclusion]OCM approach brought satisfactory clinical outcomes when applied in MIS-THA.This surgical technique shows an obvious learning curve,but requires specialized instruments.

Objective:To compare the anti-obesity effect of green tea and black tea polyphenols and investigate their molecular mechanisms. Method:Rats were divided randomly into four groups:control group,high-fat group,high-fat diet with green tea polyphenols(GTP) supplement group,and high-fat diet with black tea polyphenols(BTP) supplement group. Body weight was determined every 2 w. After 3 months,the changes of epididymal fat tissues weight and serum lipids were observed. Expressions of those genes associated with adipocyte differentiation in epididymal fat tissues of rats were measured by real-time transcription-polymerase chain reaction,including pref-1,aP2,TNF-?,leptin,PPAR-?,C/EBP-? . Results:Both GTP and BTP prevented the increase of body weight and fat induced by high-fat diet and profoundly down-regulated those adipocyte-specific genes,including aP2,TNF-?and leptin. In addition,GTP also up-regulated the pre-adipocye marker — pref-1 and reduced the expression of transcription factor,peroxisome proliferators-activated receptor(PPAR-?) . Conclusion:Tea polyphenols could prevent obesity by reversing the adipocyte differentiation,and GTP possessed stronger inhibitory effect than BTP.
