AIM: To retrospectively analyze the effect of different surgical treatment on intraocular foreign bodies, according to different types and position.
METHODS: Clinical data of 46 cases diagnosed with intraocular foreign bodies from June 2010 to April 2013 were retrospectively analyzed.
RESULTS:Intraocular foreign bodies in anterior segment could be removed or magnetically attracted directly, intraocular foreign bodies in posterior segment could be attracted if there was accurate location. Vitrectomis was more favorable for the non magnetic or intraocular foreign bodies in posterior segment. In 46 cases, all intraocular foreign bodies ( 100%) in posterior segment were removed successfully. Among them the functional cure in 33 cases ( 72%) , the anatomical cure in 12 cases ( 26%) , discharged in 1 case (2%).
CONCLUSION:The aim of operation is to reconstruct of eyeball structure preserve and restore visual function. We should find more appropriate mode of operation and timing of surgery according to the foreign bodies'different types and injury of eyeball, reduce complications, preservation eyeball and improve visual function.

Objective:To explore the clinical diagnosis and treatment methods for nasal septum malignancies. Methods:A retrospective study of seven cases of primary nasal septum malignancy was conducted. These cases were treated at the Tianjin First Central Hospital between February 1993 and October 2009. Results:Among the seven cases, one was reported malignant lymphoma, which underwent chemotherapy and radiation therapy;the other six malignant tumors included three cases of adenoid cystic carcinoma, one malignant melanoma, one chondrosarcoma, and one papilloma. Patients were treated by nasal endoscopy, external approach, lip midline incision, overturned facial surgery, chemotherapy, and radiation. During follow-up, which lasted for 2 years to 16 years from time of surgery, two fatalities resulting from recurrence or metastasis were recorded. One of these fatalities occurred after 2 years, and the other was recorded at 3 years and 4 months after surgery. Four patients survived without recurrence. Conclusion:The key treatment for nasal septum malignancies was one-time radical resection. Combined postoperative treatment and follow-up should be conducted.

Objective To observe the clinical curative effect of Gubenzhike granule on cough variant asthma (CVA), and explore its mechanism. Methods A total of 140 cases of CVA were randomly divided into two groups, 70 cases for each group. The treatment group took Gubenzhike granule orally, and the control group inhaled Budesonide Powder for Inhalation and Salbutamol Sulphate Aerosol, respectively for 8 weeks, with 8 weeks follow-up after treatment. The same nursing intervention was implemented in two groups. Cough symptom scores of the two groups were observed after treatment and at the end of follow-up, the number of eosnophils (EOS) and content of immunoglobulin E (IgE) in peripheral blood were also observed. Results The treatment group completed 67 cases and the control group completed 66 cases. After treatment, the cough symptom scores, EOS and IgE in two groups were significantly reduced (P<0.01, P<0.05), and the cough symptom score of treatment group decreased more significantly than that of control group (P<0.01). The total effective rate and recurrence rate were 91.04%and 9.84%in treatment group, and 83.33% and 30.91% in control group. The total effective rate of treatment group was better than the control group (P<0.01), and the recurrence rate was lower than the control group (P<0.01). Conclusion Gubenzhike granule showed significant effect and low recurrence rate on CVA. Good anti-inflammatory and antianaphylaxis effects may be one of its mechanisms.

Objective To analyze the CT features of primary pulmonary leiomyoma (PPL) and improve the diagnostic ability of PPL.Methods The CT findings and clinical characteristics were retrospectively analyzed in 6 patients with PPL proved by pathology,and the related literatures were reviewed.Results Six PPLs were single lesion from 3.0 to 8.5 cm in size,the shape was round or oval with extremely smooth margin.On CT plain scan,the CT values of all PPL lesions were 25-33 HU,4 lesions presented homogeneous moderate enhancement (40-60 HU) and 2 lesions presented inhomogeneous enhancement after contrast administration.A solid lesion showed obviously patchy enhancement with cystic degeneration,1 lesion presented ring enhancement.All lesions were benign histopathologically,the leiomyoma cells showed spindle shaped or in bundles with pseudocapsule,and with hyaline degeneration in 1 case.Smooth Muscle Actin (SMA) were all marked positive on immunohistochemistry.Conclusions CT findings of PPL have some characteristics,but lack of specificity,the final diagnosis still relies on pathological examination.

A 69-year-old man presented with a 3-year history of scattered erythematous patches, perifollicular papules, acneiform lesions(such as milia, cysts) on the head, trunk and limbs as well as alopecia and peripheral eosinophilia. Histopathological examination revealed chronic focal dermal and perifollicular inflammatory infiltration with vascular proliferation and presence of a small number of eosinophils. He was initially diagnosed with folliculitis, and treated with antihistamines and antibiotics. Thereafter, lesional inflammation and pruritus were attenuated. However, plaques and alopecia developed in the occipital area 3 months later. The second histopathology of biopsy specimens revealed a dense dermal infiltrate of lymphoid cells and eosinophils, perifollicular infiltrate with numerous lymphoid cells, eosinophils and atypical lymphocytes migrating into hair follicles. Alcian blue stain showed epidermal mucinosis in follicles. Immunohistochemical examination showed positive staining of atypical cells for CD3, CD4, CD5, CD2, CD43 and ubiquitin carboxyl-terminal esterase L1 (UCHL1), but negative staining for CD20, CD79a, Epstein-barr virus, CD56, phosphoglucomutase-1, myeloperoxidase, CD7, or AE1 and AE3 monoclonal anti-keratin antibodies. T-cell receptor gene rearrangement was undetected. He was diagnosed with folliculotropic mycosis fungoides. Novel skin lesions still emerged after treatment with photochemotherapy (PUVA) plus acitretin. Follow up of the patient still continued.

This study aims to construct a eukaryotic expression system for envelope gene of Jaagsiekte sheep retrovirus, observes its localization in 293T cells, and investigates the potential in inducing malignant transformation of NIH3T3 cells. By RT-PCR, the full-length cDNA of envelope gene of Jaagsiekte sheep retrovirus (exJSRV-env) was amplified from the extract of naturally infected sheep lung. The clone of target gene was sub-cloned into eukaryotic expression system pEGFP-C1, and validated by PCR, restriction endonuclease, and sequencing. Bioinformatic analysis concerning biological function and cellular localiza tion of exJSRV-env was also performed. The recombinant clone of exJSRV-env was transfected into 293T cells and NIH3T3 cells by Lipofectamine LTX. The expression and celluar localization in 293T cells were validated by confocal microscopy. Soft agar colony formation assay was employed to test the anchorage-independent growth of NIH3T3. DNA sequencing and restriction enzyme digestion with Kpn I and Hind III indicated the correct construction of the recombinant plasmid, which was named pEGFP-C1/exJSRV-env. Amino acid sequence alignment of exJSRV-env with reference sequences found 85%-100% homogeneity. A YRNM motif was discovered at the cytoplasmic tail of envelope gene, which is exclusively found in exogenous viruses. Phylogenetic tree analysis showed that our clone of exJSRV-env clustered closely with pathogenic exogenous Jaagsiekte sheep retroviruses. Fluorescence microscopy indicated typical membrane localization of exJSRV-env protein. NIH3T3 cells transfected with exJSRV-env lost contact inhibition, and acquired colony forming ability in soft agar. This study indicated that envelope protein of Jaagsiekte sheep retrovirus can induce malignant transformation of mouse fibroblast cell NIH3T3. Discoveries of this study provide a basis for further structural and functional research on Jaagsiekte sheep retrovirus envelope protein.
