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.

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

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.

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.

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

To detect the expression of the human papilloma virus (HPV) 16 and HPV18 in esophageal squamous cell carcinoma in Minnan area. Methods: Real-time fluorescence quantitative polymerase chain reaction (FQ-PCR) was applied to detect HPV DNA in 100 esophageal carcinoma sample and 100 normal tissues beside the tumor. Results:The positive rates of high-risk HPV 16 and HPV 18 infection in Minnan esophageal carcinoma and in normal tissues beside the tumor were 14.00%, 15.00%and 7.00%, 8.00%, respectively. The positive rates of lymph node and non-lymph node metastases were 40.98%and 10.25%, respectively. These re-sults exhibited statistical significance (P<0.01). HPV 16 and HPV 18 infection was uncorrelated with patient age, pathological type, and tumor grade (P>0.05). Conclusion:HPV16 and HPV 18 infection was correlated to esophageal squamous cell carcinoma in Minnan ar-eas. Such infection may also contribute to the occurrence and development of esophageal squamous cell carcinoma.
