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.

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.

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.

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 The non intrusive ultrasound combined with western medicine in the treatment of chronic prostatitis prostate/research and analysis of the effect of chronic pelvic pain syndrome.Methods96 cases of chronic prostatitis patients who were treated in our hospital from September 2016 to were randomly divided into the observation group, the control group 1 and the control group2.The observation group was treated with western medicine in the treatment of non intrusive prostate ultrasound;1 patients in the control group were given a single non intrusive prostate ultrasound treatment;control group 2 given a single treatment with Chinese and Western medicine.The clinical symptoms and NIH-CPSI scores were evaluated before and after treatment in each group.ResultsComparison between groups of patients before treatment NIH-CPSI score, no significant difference;after treatment, the NIH-CPSI score has decreased, there are obvious differences (P<0.05);the patients in the observation group were decreased significantly, the total score before treatment (26.21±2.20), the total score after treatment (11.77±1.90), there are obvious the difference (P<0.05).The treatment groups were compared with the efficiency, the total efficiency of observation group was 93.75%, the control group of 1 patients with the total effective rate was 75%, the control group of 2 patients with the total effective rate was 68.75%, there was significant difference in the treatment effect, with statistical significance (P<0.05).ConclusionNon intrusive ultrasound combined with western medicine in the treatment of prostate in compared with non intrusive ultrasound therapy and Western medicine alone in the treatment of prostate, has more significant treatment effect, should strengthen the clinical application and promotion.

Objective To produce an erythrocytic stage chimeric protein of Plasmodium berghei in Pichia pastoris and evaluate its immunogenicity. Methods The DNA sequences of AMA1 (Ⅲ) and MSP1-19 from P. berghei homologous to the corresponding sequences of P. falciparum chimeric antigen 2.9 (PfCP-2.9) were fused to generate a chimeric gene, designated as PbCP-2.9. The resulting gene was redesigned using Pichia preferential coden usage and expressed in P. pastoris in the secreted form. The recombinant protein was purified by Ni-NTA affinity chromatography. Three groups each with 10 BALB/c mice were im- munized subcutaneously with 20 ?g of purified PbCP-2.9 antigen formulated in Freund’s adjuvant, Montanide ISA720 and Montanide IMS 1 312, respectively. Three control groups each with 10 mice received only adjuvants emulsified with PBS. All the mice received three immunizations at 2-week intervals with the same dose of antigen. Serum samples were collected at preimmunization and one week after each immunization, and were analyzed for specific antibodies by ELISA and reaction with natural P. berghei proteins by IFAT. Results The PbCP-2.9 antigen with Mr 26 400 was successfully expressed in P. pastoris in secret- ed form. The recombinant protein can be recognized by the serum against blood stage parasites of P. berghei. High antibody responses were detected in all three PbCP-2.9-immune groups of mice by ELISA. However, mice immunized with PbCP-2.9 antigen in Freund’s adjuvant produced higher antibody titers than those with PbCP-2.9 antigen in Montanide ISA 206 and Montanide IMS 1312 adjuvants. The mean antibody titer in Freund’s adjuvant was 6.9-fold higher than in Montanide ISA 206 adjuvant and 5.6-fold higher than in Montanide IMS 1312 adjuvant after the second immunization (F=81.06, P
