Objective The double-cavity balloon oppressor surgery for rhegmatogenous retinal detachment (RRD) has been utilized in past decades. But we have not yet a domestic device available. Present study was to investigate the effectiveness of double-cavity balloon oppressor using a domestic device in primary RRD surgery. Methods This clinical trial was a prospective study. Total 74 cases of patients with rhegmatogenous retinal detachment(RRD) (74 eyes) were enrolled. Double-cavity balloon oppressor surgery was performed in 40 eyes of 40 patients, and conventional segmental scleral buckling surgery was used in 34 eyes of 34 patients. The mean operative time, retinal attachment rate, vision and astigmatism change after operation between two different operative fashions were compared. The intra- and post-operative complication was discussed. The mean follow-up period was 4. 5 months. Written informed consent was obtained from all the patients before clinical trial. Results The retinal anatomic attachment rate was 92. 5% (37/40) in balloon oppressor surgery group and 91. 1% (31/34) in conventional surgery group, and there were no significant difference in retinal attachment rate among PVR grade A, B and C1 (P >0. 05) . The postoperative best corrected visual acuity (operative 3 months) was improved in 29 eyes(72. 5%) after balloon oppressor surgery and 25 eyes(73. 5%) after conventional surgery, showing insignificant difference between them (P > 0. 05) . The mean surgical time was about (27. 00 ±8. 60) minutes in balloon oppressor surgery group and (47. 00 ± 14. 30) minutes in conventional surgery group(t =7. 41, P <0. 01) . Cylinder diopter change after surgery was insignificantly different between before and after operation in balloon oppressor surgery group (0. 52 ± 0. 30 D vs 0. 81 ± 0. 41 D, P > 0. 05), however, there was a significant difference in cylinder diopter change between preoperation and postoperation (0. 65 ± 0. 32 D vs 1. 83 ± 0. 69 D, P < 0. 05) . Conclusion Double-cavity balloon oppressor surgery for RRD is accurate and reliable. This operation procedure offer an economic, efficient and convenient choice for treatment of RRD.

BACKGROUND: Biological function of leukocyte-associated immunoglobulin like-receptor 1 (LAIR 1) has clearly researched in China and abroad, but the in vivo biological function of LAIR is poorly understood. OBJECTIVE: To establish LAIR-2 (CD306) eukaryotic expression vectors and to purify and identify the fusion protein. DESIGN, TIME AND SETTING: A single sample observation experiment was performed at the Fourth Military Medical University of Chinese PLA between June 2007 and June 2008.MATERIALS: plg/3c vector was offered by Oxford University, pcDNA3.1 vector was provided by Meyaard doctor. Chinese hamster ovary (CHO) cell lines were preserved by the Department of Immunology, Fourth Military Medical University of Chinese PLA.METHODS: Two eukaryotic expression vectors plg/3c-LAIR-2 and pcDNA3.1-LAIR-2 were constructed and were transfected into CHO cells. The binding activities of LAIR-2 fusion protein to LAIR-2 mAbs were identified by Western blot, immunocytochemistry and flow cytometry assay.MAIN OUTCOME MEASURES: The construction of stably transfected cell lines, and the purification and identification of fusion protein. The activity of LAIR 2 protein combined to corresponding monoclonal antibody.RESULTS: Eukaryotic expression vectors were constructed and trasnsfected into CHO cells successfully. Two cells lines CHO/LAIR-2-Fc and CHO/LAIR-2 that steadily expressed LAIR-2-Fc fusion protein and LAIR-2 protein were established. Western blot assay showed that LAIR-2 protein could bind specially to LAIR-2 mAb 1A7, 3H12 and 4A9. Immunocytochemistry and flow cytometry assay demonstrated that 3H12 and 4A9 could bind to LAIR-2 expressed in the transfected CHO cells. CONCLUSION: Two ceils lines CHO/LAIR-2-Fc and CHO/LAIR-2 were successfully constructed, which can transfected to CHO cells. The eukaryotic expressed LAIR-2 protein has good binding activity to LAIR-2 mAbs.

Objective To explore whether 5 to -7-day of folic acid supplementation prior to pemetrexed therapy is needed. Methods We retrospectively evaluate the outcomes of non-small cell lung cancer patients received less than the advised folic acid premedication. Seventy patients with Ⅲ-Ⅳ NSCLC were randomly divided into two groups: patients who initiated vitamin supplementation on 7 days before the first dose of pemetrexed (group A) and patients who initiated vitamin supplementation on the day of the first dose of pemetrexed (group B). Results In group A and group B, CR 0 and 0, PR 10 and 8, the response rates of 28.6% and 22.9% were observed, respectively. There was no statistically significant differences between these two groups. No significant differences were observed in the incidence of hematologic and non-hematologic toxicities. Conclusions The initiation of pemetrexed-based chemotherapy does not need to accommodate a vitamin supplementation schedule.

Objective: The cytologic methods were used in the diagnosis of cancerous change of (intraductal papillomas,IP) and its significance was discussed. Methods: We studied the nipple discharge smear by using Wright-Gimsa staining. Meanwhile, infrared ray scanning B-ultrasound and X-rays were performed. Results: One hundred and twenty-eight patients were with IP, among them, 15 (11.7%)were confirmed as tumors by surgery and pathological examination. The cancerous change of cytomorphology was based on IP. The average age of patients with cancerous change was 48.1.The nipple discharge in patients with cancerous change was primarily bloody(66.7%). Conclusion: Introductal papillomas is carcerous. The possibility of canceration in persons with longer time of nipple discharge is larger than those with shorter time of nipple discharge. Women who are elder than 45 years old, with nipple discharge and post menopause, should be considered to have the possibility of cancerous change.
