AlM: To compare the clinical effects of two different surgical ways on congenital cataract.
METHODS: We selected 52 children ( 84 eyes ) with congenital cataract surgery between December 2009 and December 2012 in our hospital. They were divided into two groups based on the surgical way: A group were treated by phacoemulsification + posterior curvilinear capsulorhexis, B group were treated by phacoemulsification+posterior curvilinear capsulorhexis+anterior vitrectomy. The follow-up was 6-12mo, and postoperative corrected visual acuity and complications were observed.
RESULTS: Postoperative visual acuity of two groups were increased ( P< 0. 05 ). Preoperative visual acuity between two groups had no significant difference ( P>0. 05 ) , while postoperative visual acuity between two groups had significant difference (P<0. 05), group B was better than group A. Complications had no significant difference between two groups except posterior capsule opacification (PCO) (P<0. 05). The incidence rate of PCO in group B (12%) was far lower than group A (53%).
CONCLUSlON: Compare with phacoemulsification +posterior curvilinear capsulorhexis, the way combined with anterior vitrectomy can improve the postoperative visual acuity and decrease the incidence rate of PCO.

Objective To investigate the changes of serum vascular endothelial growth factor (VEGF) and its effects on pathoge nesis in children with Henoch - Schonlein purpura(HSP). Methods Serum VEGF was detected by sandwich ELISA in 20 children with HSP in acute phase and 15 children in remission phase and 16 normal children. Results The serum VEGF levels in children with HSP in acute phase(533.85? 127.63) ng/L were significantly higher than those in remission phase (160.47 ? 37.39) ng/L and normal control (68. 93 ? 19. 16) ng/L. One - way analysis of variance between them was significant difference ( F = 158. 86 P

Chondroblastoma of the patella, rare occurred in patellar,is a kind of an uncommon benign bone tumor. Compared with giant cell tumor, the morbidity of chondroblastoma is lower. Meanwhile, its clinical manifestations are various, and images are very complicated. Therefore, the understanding of this kind of tumors may be limited even to the orthopedist. The differences of patellar chondroblastoma between other tumor in X-ray, CT and MRI is a spot in recent years. Sometimes patellar chondroblastoma coexists with aneurysmal bone cyst, which is a challenge to obtain an accurate pathological and radiological diagnosis. For the treatment, curettage and bone grafting is one the most popular method, but whether to perform a biopsy before surgery still remain controversy. Some new technique still has an unknown prospect for the treatment such as radiofrequency ablation.

Erectile dysfunction was one of the most frequently postoperative complications after radical prostatectomy,which has been deeply concentrated by patients and urologists,along with more and more people were diagnosed as localized prostate cancer.Widely being used for erectile dysfunction after radical prostatectomy,the efficacy and safety of phosphodiesterase type 5 inhibitors have been confirmed by many clinical studies.However,the influences of phosphodiesterase type 5 inhibitors on the occurrence and progression of cancer are still not completely revealed at present.Additionally,the efficiency of phosphodiesterase type 5 inhibitors on biochemical recurrence after radical prostatectomny is still controversial,though it has been demonstrated that phosphodiesterase type 5 inhibitors is not associated with the occunrence of prostate cancer based on recent clinical studies.We will review the possibly mechanisms of phosphodiesterase type 5 inhibitors in oncologic occurrence,especially in the occurrence of prostate cancer and its biochemical recurrence after radical prostatectomy.

In recent years, the incidence of pediatric malignancies has gradually increased. High-risk patients have poor prognosis, and the main effect of treatments such as surgery and radio-chemotherapy has reached a plateau phase. Targeted therapy, with its reliable efficacy and mild toxicity, has become one of the most promising approaches. Anaplastic lymphoma kinase (ALK) is a receptor tyrosine kinase, and its abnormal forms include gene fusion, gene mutation, gene amplification, and protein overexpression. These aberrations play important roles in the development of childhood cancer. With the application of ALK inhibitors in clinical anti-tumor therapy, targeted ALK treatment has received increased attention. This article aims to review various studies on the relationship between ALK aberrations and pediatric malignancies.

The Roles of the clinicians in different medical models are quite different,which not only led to the change of the relationship between the clinicians and the patients, but also had a significant clinical effect. The authors compared the clinicians'role in different medical models and showed the humanism underlying this change.

Objective To study the clinical significance of partial splenic embolization (PSE) for the treatment of hypersplenism and the relationship between the therapeutic effect and the area of embolization. Methods Sixteen patients with hypersplenism were divided randomly into two groups: Group 1 (n=5) and Group 2 (n=11). The embolization area in Group 1 was 40%-59% and that in Group 2 was 60%-80%. A follow-up for 1 year was conducted in all patients. Results The short-term effective rates (CR+PR) of thrombocyte count were 81.3% in Group 1 and 93.8% in Group 2, respectively, whereas the long-term effective rates were 62.5% and 87.5%, respectively, and the corresponding one-year recurrence rates were 23.1% and 6.7%. The long-term effective rates of WBC count were 71.4% and 82.2% in groups 1 and 2, respectively, and the one-year recurrence rates were 28.6% and 17.8%, respectively. The long-term effective rates of RBC count were 70% in Group 1 and 83.3% in Group 2, respectively, and the one-year recurrence rates were 22.2% and 11.8 %, respectively. Conclusion PSE, resulting in a low recurrence rate, is effective in treating hypersplenism.

Objective To present 3 cases of neurilemmoma of adrenal gland. Methods The clinical pathological manifestations,diagnosis and treatment of 3 cases of neurilemmoma of adrenal gland were reviewed. Results Tumor resection was undertaken in all the three and the diagnosis was assessed on pathological study. All the 3 patients have been in good condition and tumor free on 3～5 years of follow up. Conclusions Tumor resection is the treatment of choice with good prognosis.Radiotherapy may be considered as an adjuvant treatment for malignant ones.Definite diagnosis depends on pathological studies.

Objective To investigate the role of compound traditional Chinese medicine Yiqilin in the regulation of immune-related genes expression in spontaneously hypertensive rats(SHR).Methods Ten SHR were randomly divided into test group(fed with Yiqilin and ordinary food at the ratio of 1:9 for 6 months,n=5)and control group(fed with ordinary food for 6 months,n=5).Total RNA was extracted from myocardial tissues of SHR after 6 months,and gene chip hybridization technique was employed to analyse the expression of immune-regulated genes of myocardial tissues in two groups.The genes with differentiation expression were screened,and were verified by Real-time PCR.Results The expression of 32 immune-related genes were up-regulated in the test group,including interleukin(IL)6 receptor,IL-6 signal transduction factor,chemotatic factor,antigen presenting molecule,antibody receptor,heat shock protein(Hsp), etc.No immune-related gene was down-regulated in test group.The results of 2 immune-related genes(Hsp 105 and Hsp 90)detected by Real-time PCR were consistent with those by gene chip hybridization.Conclusion Part of the immune-related genes in myocardial tissues in SHR may be up-regulated by Yiqiling,which indicates that Yiqiling may play a role in the regulation of expression of immune-related genes in SHR.
