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.

Increasing aged care requisite has become a serious challenge all over the world. Compared with developed countries, aged care in China still has some limitations, i.e., lack of qualified professionals, aged care system needs to be improved, and lack of aged long term care insurance. This article discussed these points and put forward the corresponding countermeasures.

Objective To compare the efficacy of arthroscopic synovectomy between early and middle stage rheumatoid arthritis. Methods A total of 34 cases of rheumatoid arthritis (42 knee joints) either in early stage (22 cases, 24 joints) or in meddle stage (12 cases, 18 joints) underwent arthroscopic synovectomy. The bipolar radiofrequency was used for the synovial debridement and hemostasis in 32 knee joints. Postoperatively, routine anti-rheumatoid drugs were administrated. Follow-up observations in the two groups included the evaluation of knee function, the erythrocyte sedimentation rate (ESR), the C-reaction protein (CRP), and the rheumatoid factor (RF). Results The rate of excellent or good results was 91.7% in early stage (22/24) and 66.7% in middle stage (12/18), without statistical significance between the two groups ( ? 2=2.705, P =0.100). Conclusions Arthroscopic synovectomy is effective for the treatment of rheumatoid arthritis in both early and middle stage. Bipolar radiofrequency is helpful for the complete elimination of the synovium, the prevention of joint hematoma, and the rehabilitation of joint function.

To study the significance of detection of K ras mutation in stool samples in the diagnosis of large intestinal cancer, stool and local tissue samples were collected from consecutively diagnosed patients, among them 23 cases suffered from large intestinal cancer, 20 cases from colorectal adenomatoid polyps and 20 healthy subjects. DNA was extracted from both the stool and the tissue, K ras gene mutations at the first and second base of codon 12 were studied by allele specific mismatch method in both of them. The results showed that K ras mutation rate in large intestinal cancer was 56 52%(13/23), which was much higher than 5%(1/20)in healthy subjects( P 0 05). There was a 92 31%(12/13)incidence of K ras mutation at the second base of codon 12 in large intestinal cancer. The results of detecting the K ras mutation were highly identical in both the stool and the tissue ( P

Objective To study the early effect of arthroscopic bipolar radiofrequency technique in the treatment of patellofemoral malalignment. Methods 42 patients(47 knees) who were confirmed to be patellofemoral malalignment by radiographic methods, underwent arthroscopic bipolar radiofrequency chondroplasty and lateral retinacular release. The cartilage abnormality were classified according to the Outerbridge grade. 34 cases(37 knees) were followed up and mean period was 18.3 months. Patients were assessed before and after surgery using the Kujala patellofemoral score. Patellofemoral alignment were evaluated through MRI in 23 of 37 knees. The change of Cac (congruence angle of cartilage), Tac(tilt angle of cartilage), LPDc (lateral patellofemoral distance of cartilage) and LPFac(lateral patellofemoral angle of cartilage) were measured. Results The patellofemoral joint score was improved significantly in OuterbridgeⅠ,Ⅱand Ⅲ grade patients(6 knees ofⅠgrade: 60.83?3.54 preoperatively and 82.50?9.22 postoperatively, P0.05). The score of all these 37 knees was improved from 55.86?9.39 preoperatively to 69.41?14.89 postoperatively(P
