Objective To observe the therapeutic effect and safety of heavy silicone oil used as internal tamponade to treat complicated retinal detachment. Methods Retrospective 15 patients ( 15 eyes)with complicated retinal detachment, whose retinal detachment arising from inferior retinal tears. Heavy silicone oil was applied to patients during vitrectomy. Results The mean follow-up was (4.20 ± 1.62)months. Retinal reattachment and holes were closed in 15 cases. Conclusions The study shows that heavy silicone oil tamponade is effective to treat complicated retinal detachment and relatively few complications.However, its emulsification period is relatively short, which may constrain its application to a certain extent.

Objective To discuss the value of CT guided biopsy of the retroperitoneal lymph nodes for diagnosis.MethodsTotally 18 patients with enlarged retroperitoneal lymph nodes underwent CT-guided biopsy in our hospital between June 2006 and June 2007.Results The results of CT were identified by the pathological examination in 94.4%(17/18) of the patients.The operation time of the biopsy was 20 to 40 minutes.CT scan was performed for 3 to 6 times(mean,4.1) during the procedure.No severe complications occurred in this series.Conclusion CT-guided biopsy of enlarged retroperitoneal lymph nodes is a safe and effective diagnostic method.

As a node between the skull and the spine, atlantoaxial joint plays a pivotal role in the maintenance of head and neck activities, as well as the connection between the brains and the spine. The biomechanical characteristics of stlantoaxial joint, together with traumatic factors, contribute to determine the site, type and character of atlantoaxial joint fracture and dislocation, they also affect the treatment of atlantoaxial joint injury. With the materials technique development and accumulated experience of clinical operations, various types of new implants are increasing and used for clinical practice, accordingly the surgical approach and therapy regimen of atlantoaxial disease have been greatly enriched. At present, the use of implant mainly aims to promote the atlantoaxial fusion or enhance the connection and fixation between atlantoaxial joints. However, the head and neck activities are also limited simultaneously while the implant enhances the atlantoaxial joint stability. Further studies require to handle the correlation between joint stability and joint flexibility and to maximize the physiological function recovery of atlantoaxial joints when ensuring the atlantoaxial joint stability.

In this mini review,some research advance on Marinomonas from domestic and overseas was briefly summarized,mainly including of its classification、ecological distribution、functional genes and bioactive molecules.Furthermore,some suggestion and perspectives for further studies on Marinomonas were also proposed.

60 Candida strains were analyzed with randomly amplified polymorphic DNA(RAPD) from HIV-infected patients' oral cavity.The results showed that RAPD-PCR fingerprinting appeared from zero to five bands whose size rang from 300 bp to 2 kb with P2 primer,Candida albicans have three characteristic bands of 300 bp,400 bp and 600 bp in size,non-Candida albicans have the similar bands.They can be clas-sified five genetic clusters and 14 genotypes by Cluster Analysis,two Candida albicans(P385&P403) with fluorocytosine-resistance were classified into C1 genotype for "Squared Euclidean Distance" being 0.115,one Candida albicans(P321) and one Candida glabrata(P522) who were resistant against Amphotericin B were classified into D1 genotype for "Squared Euclidean Distance" being 0.221.So,an abundant genetic polymorphism appeared in Candida species related HIV,RAPD could be as a reference for genotype of Candida albicans;different Candida speices had some special bands,different Candida strains had similar bands in the same species;it is perhaps that some genotypes were relevant to drug resistance.

The effect of iodinated contrast on thyroid function and auto-antibodies after a single percutaneous coronary intervention (PCI) was explored.In 96 patients with randomly selected PCI,serum TSH,T3,T4,thyroid peroxidase antibody (TPOAb),thyroglobulin antibody (TgAb) were determined preoperatively as well as by 3-6 months postoperatively.After PCI,the level of TSH,T3,T4,showed no significant changes; TgAb,TPOAb which were positive preoperatively,after 3-6 months were statistically increased(P＜0.05).Iodinated contrast in PCI has no significant influence on thyroid function and auto-antibodies after 3-6 months.

OBJECTIVETo evaluate the diagnostic value of magnetic resonance (MR) imaging in the diagnosis of mandibular invasion caused by oral cancers.

METHODSMedline, EMBASE, SIGLE, and Chinese biomedical literature database were searched electronically. Manual searching for 19 relevant Chinese journals was also performed. Two reviewers evaluated the literature and extracted the data. Meta-Disc 1.4 was chosen to conduct the sensitivity (SEN), specificity (SPE), and 95% confidence interval (95%CI).

RESULTSTwelve studies with a total of 476 patients, namely, 5 prospective studies and 7 retrospective studies, were included. All the studies had unclear risk of bias. Meta-analysis result showed that the combination of SEN of MR in diagnosing mandibular invasion was 0.779 (95%CI: 0.719-0.831), combination of SPE was 0.823 (95%CI: 0.767-0.870), positive likelihood ratio was 3.442 (95%CI: 2.181-5.431), negative likelihood ratio was 0.286 (95%CI: 0.181- 0.451), and diagnostic odds ratio was 25.702 (95%CI: 13.406-49.273). The area under curve was 0.903 9 and Q* was 0.835 4. Meta-analysis was not processed when diagnosing mandibular medullary invasion because only two studies with 55 patients had been reported. The SEN was 0.838, and the SPE was 0.722.

CONCLUSIONMR is efficient and has clinical value in the diagnosis of mandibular invasion caused by oral cancer.
