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 evaluate the effect of topical anesthesia with compound lidocaine cream coated on the tracheal tube on extubation response in patients undergoing Han-uvulopharyngoplasty (H-UPPP).Methods Eighty-four patients,aged 28-48 yr,weighing 91-108 kg,scheduled for elective H-UPPP,requiring tracheal intubation under general anesthesia,were equally and randomly divided into 2 groups:compound lidocaine cream group (group L) and control group (group C).The compound lidocaine cream 2-3 g were coated on the tracheal tube cuff and exterior before induction of anesthesia in group L,while the paraffin oil was coated in group C.Mean arterial pressure (MAP),HR and pulse oxygen saturation were recorded before induction of anesthesia,at the end of infusion of anesthetics,during extubation and 5 min after extubation (T1-4).Blood samples were taken from the forearm veins on the noninfusion side at T1-4 for detection of plasma adrenergic and norepinephrine concentrations.Cardiovascular events during extubation were recorded.Results Compared with group C,MAP and HR were significantly decreased at T3,4,the incidences of hypotension and tachycardia were decreased,the plasma adrenergic and norepinephrine concentrations were significantly decreased at T2-4 in group L (P ＜ 0.05).Conclusion Topical anesthesia with compound lidocaine cream coated on the tracheal tube can effectively reduce the extubation response in the patients undergoing H-UPPP.

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.

Objective To evaluate the efficiency of levonorgestrel-releasing intrauterine system (LNG-IUS) in the treatment of recurrent endometriosis after conservative surgery or conservative surgery combined with medical treatment. Methods Twenty-three patients with recurrent endometriosis after conservative surgery or conservative surgery combined with medical treatment were treated by LNG-IUS. All patients rejected further operation and had no desire of fertility. The visual analogue scale (VAS) scores of pain, menstrual model, weight and serum CA125 level and the volume of ovarian endometriotic cysts before and after 3, 6, 12, 24 and 36 months of treatment were recorded and compared. Results ( 1 ) VAS score:after 12 months of using LNG-IUS, dysmenorrheal, chronic pelvic pain or dyspareunia were relieved significantly. VAS score were dropped from 5.9 ± 2. 3,4. 3 ± 2.0 to 1.0 ± 0. 7,1.4 ± 1. 1 ( P ＜ 0. 01 ). ( 2 )Volum of cysts :after 6 months of using LNG-IUS, the volume of recurrent ovarian endometriotic cysts in 11 patients were reduced from ( 11.4 ± 6. 1 ) em3 to ( 5. 5 ± 3.4 ) em3 significantly ( P ＜ 0. 01 ). At 12 months of follow-up, it suggested that 2 patients' ovarian endometriotic cysts disappeared. At 24 months follow-up,9 patients ovarian endometriotic cysts disappeared ( 3 ) CA125: serum CA125 decreased from ( 65.5 ± 19. 6 )kU/L to (42. 1 ± 13.6) kU/L at 6 months after treatment remarkably (P ＜ 0. 01 ). Continued to decrease after 12 months and then become steady. Irregular bleeding and spotting was the main side effects, weight gain was also observed in few patients. Conclusions LNG-IUS could be used in treatment of recurrent endometriosis after conservative surgery or conservative surgery combined with medical treatment effectively. It could relieve pain, reduce the level of CA125 and decrease the size of ovarian endometriotic cysts. LNG-IUS seems to be an effective, safe, and long term treatment for endometriosis with fewer side effects and better compliance.

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.
