The microbial community structure of 4 kinds of sponges in South China Sea were revealed using culture-independent PCR- DGGE gene fingerprint technique as well as the mixed culturable microorganism. The relationship between the culturable and un-culturable microorganism was studied based on the different fingerprint profile. It was found that there is host specificity for microorganism in different sponges from the same marine area. Culture condition such as medium is an important factor for sponge-associated microbial cultivation and the culturable microorganism amount to only a little part of the total sponge-associated microorganisms.

AIM: To investigate the indications and therapeutic effect of the conservative treatment and surgical treatment for vitreous hemorrhage.
METHODS: Hemorrhage reasons, degree of illness, and treatment and final results of vitreous hemorrhage were recorded from 2008 to 2013, and curative effect of different treatments was analyzed.
RESULTS:Selected 22 cases ( 24 eyes ) of conservative treatment, vision degree of 6 eyes ( 25%) had raised, 5 eyes ( 21%) occurred secondary retinal detachment without treatment, 3 eyes (12. 5%) suffered neovascular glaucoma were underwent operation, but the vision had lost completely. In 26 cases ( 31 eyes ) of control (operation) group, vision of 17 eyes (55%) had improved, 2 eyes (6. 5%) suffered the second operation, 2 eyes (6. 5%) suffered the third surgery, 3 eyes (10%) suffered eyeball atrophy. The number of ultimate vision improved with conservative treatment were significantly lower than the number of cases with surgical treatment (P<0. 05).
CONCLUSION: The surgical treatment is still visible vitreous hemorrhage treatment means of positive, but there will be eyeball atrophy and other serious complications, so we should choose a different methods in according to the different treatment objects and treatment time.

Objective To detect the infection of human papillomavirus (HPV)in patients with non-small cell lung cancer (NSCLC)and explore the relationship between HPV infection and clinicopathological features.Methods HPV detection and genotyping in 156 cases of NSCLC were performed using a new liquid chip based on Luminex.Patient clinical characteristics were also recorded,and the relationship between HPV infection and clinicopathological features was studied.Results Of the 156 tumor-DNA samples tested,40 (25.6%)cases showed presence of HPV-DNA,of which 37 cases were of a high-risk HPV type (16,18,33, 58).The differences were statistically significant between the HPV-positive and HPV-negative groups in gender (χ2 =4.387,P =0.036),smoking (χ2 =8.130,P =0.004),histologic type (χ2 =4.075,P =0.044)and lymph node metastasis (χ2 =7.082,P =0.008).The differences were not statistically significant between the HPV-positive and HPV-negative groups in age (χ2 =0.013,P =0.910),differentiated degree (χ2 =1.727, P =0.189),clinical stages (χ2 =0.179,P =0.672),distant metastasis (χ2 =3.012,P =0.083).Logistic regression analysis revealed that lymph node metastasis alone was an independent predictive factor of HPV infection in NSCLC (OR =0.384,95%CI:0.153-0.967,P =0.042),and gender (OR =1.402,95%CI:0.522-3.769,P =0.503),smoking (OR =0.506,95%CI:0.194-1.322,P =0.506),histologic type (OR =0.393,95%CI:0.133-0.161,P =0.091)were not independent predictive factors of HPV infection. Conclusion The infection of HPV presents in part of Chinese NSCLC patients,and HPV infection may be connected with occurrence and development of lung cancer.

Abstract?AlM:To evaluate the accuracy and practicability of three - dimensionally preformed Arbeitsgemeinschaft Osteosynthese AO titanium mesh plates for orbital fractures.?METHODS:Forty-seven patients with isolated blow-out orbital fractures were included in this study. Fracture locations were as follows: floor/medial wall ( n = 26, 55%), medial wall ( n = 12, 26%), and floor ( n = 9, 19%) . The floor fractures were exposed by a standard transconjunctival approach, whereas a combined transcaruncular transconjunctival approach was used in patients with medial wall fractures with temporary dissection of inferior oblique muscle. A three -dimensionally preformed AO titanium mesh plate was selected according to the size of the defect previously measured on the preoperative computed tomographic scan examination and fixed at the inferior orbital rim with 2 screws. The accuracy of plate positioning of the reconstructed orbit was assessed on the postoperative computed tomography ( CT) scan. The practicability of clinical use of AO three - dimensionally preformed titanium mesh plates was assessed on the preoperative and postoperative clinical data.?RESULTS: Postoperative orbital CT scan showed an anatomic three- dimensional placement of the orbital mesh plates in all of the patients. All patients had a successful treatment outcome without clinical complications. 40 patients ( 87%) had a successful enophthalmos correction. 25 patients ( 86%) had a successful recovery from diplopia.?CONCLUSlON: Three- dimensionally preformed AO titanium mesh plates for orbital fracture reconstruction results in an accurate anatomic restoration of the bony orbital contour with a high rate of success to correctenophthalmos and diplopia.
