AIM:To evaluate the efficiency of vitrectomy combined with inferior scleral buckling for a special kind of retinal detachment.
METHODS: Nineteen eyes of special retinal detachment had following features: 1 ) the course was more than 6mo;2) there were at least one hole located in the 5 : 00 - 7 : 00 of the marginal retina; 3 ) the detachment range of retina more than 270 degrees and retinal proliferation in retinal detachment. The 19 eyes who received vitrectomy combined with inferior scleral buckling, retinal anatomic reattachment and visual function recovery was observed.
RESULTS: Among these 19 eyes, all eyes retinal anatomic reattachment and best corrected visual acuity ( BCVA ) was improved in various degrees. The BCVA was 0. 01-0. 1 in 5 eyes, 0. 12-0. 3 in 9 eyes, and ≥0. 4 in 5 eyes.
CONCLUSION: It is an effective method to vitrectomy combined with inferior scleral buckling for the special kind of retinal detachment which has following features:1) the course was more than 6mo;2) there were at least one hole located in the 5:00-7:00 of the marginal retina;3 ) the detachment range of retina more than 270 degrees and retinal proliferation of cable in retinal detachment.

Objective To improve the diagnosis and treatment of testicular masses associated with congenital adrenal hyperplasia(CAH).Methods A 25-year-old man presented with bilateral testicular nodules.Physical examination revealed palpable multiple nodules in the bilateral testes and epididymides as well as enlarged and hard right testis with uneven surface.Biochemical examination showed testosterone(T) of 18.7 nmol/L,17?-(OH)P＞20.0 ng/ml,positive results of rapid ACTH stimulation test and dexametha- sone suppression test.B-ultrasound demonstrated diffuse testicular lesions with nodules in parts of the bilater- al testes.Bilateral testicular nodules were biopsied,and pathological diagnosis was interstitial cell hyperplasi- a.Positive staining for?-inhibin was observed immunohistochemically.The clinical characteristics of testicular masses associated with CAH were reviewed in combination with the literature.Results Based on medical history,imaging,laboratory and pathologic examinations,the patient was diagnosed with testicular masses as- sociated with CAH.He received oral cortisol at dose of 40 mg daily for 2 weeks,and then at dose of 30 mg daily as maintenance therapy.After treatment of 8 months,B-ultrasound showed complete regression of the testicular tumors.Follow-up of 24 months showed no recurrence of the tumor.Conclusions For patient with bilateral testicular masses,endocrinological evaluation and clinical history taking are indicated to exclude testicular interstitial cell hyperplasia associated with CAH.By oral steroid replacement therapy,hormone-sen- sitive testicular masses can regress.

This study is to investigate the protective effect of mangiferin on NF-kappaB (P65) and IkappaBalpha expression in peripheral blood mononuclear cell (PBMC) in rats with cigarette smoke induced chronic bronchitis. The rat model with chronic bronchitis was established by cigarette smoke. Real-time fluorescence RT-PCR was executed for evaluating the NF-kappaB (P65) and IKkappaBalpha gene expression in mononuclear cell, and flow cytometry for their protein expression. The serum hs-CRP (high-sensitivity C-reactive proteins) and TNF-alpha (tumor necrosis factor-alpha) were detected by enzyme-linked immunosorbent assay. The histopathological score was obtained from lung tissue HE staining slides of lung tissue. The results showed that mangiferin could markedly suppress the NF-kappaB (P65) mRNA and protein expression in mononuclear cell, while promote the IkappaBalpha mRNA and protein expression. Furthermore, mangiferin could lower serum hs-CRP and TNF-alpha level, and reduce the chronic inflammatory damage of bronchiole. These results suggested that mangiferin could notably ameliorate chronic bronchiole inflammation induced by cigarette smoke, and this protective effect might be linked to the regulation of NF-kappaB (P65) and IkappaBalpha expression in mononuclear cell.

The mechanism of bone marrow relapse in pediatric acute lymphoblastic leukemia has been deeply researched in recent years. The roles of hematopoietic stem cells, some gene abnormalities including IKZF1, JAK, CRLF2 and CREBBP, as well as mutation of genes influencing drug resistance have been confirmed to related with relapse of disease. The microRNAs, gene expression profile of patient, microenvironment of bone marrow including bone marrow fibrosis, mesenchymal stem cells and matrix metalloprotease, also play an important role in the process of leukemia recurrence. This article reviewed the details mentioned above.
