This paper reports the study and design of a visualization system of the ultrasonic rhinitis therapeutic apparatus with the function of endoscopic sinus. On Linux operating platform, we captured the video data of a video capture card that connected the endoscopic sinus using Video4Linux (V4L2) that was provided by the operating system. The video images were displayed by Qt. The visualization system solved the problem that the current ultrasonic rhinitis therapeutic apparatus had to rely on the large and expensive endoscopy equipment. And this simplified the doctors' operation, met the need of monitoring nasal cavity in the process of operating, greatly reduced the costs of treatment and would contribute to the promotion of the instrument. As a result, it has been tested that the nasal endoscopic image achieved by the system is clear and smooth, and fully meet the clinical needs of ultrasonic treatment of rhinitis.

Apolipoprotein A-I (apoA-I) is a member of the apolipoprotein A family, which was discovered the earli-est. It has an important role in the regulation of lipid metabolism, which mainly includes cholesterol synthesis and transfer. Therefore, apoA-I is closely related to hyperlipidemia and atherosclerosis. Clinically, serum ApoA-I/ApoB has been used as one of the indexes of hyperlipidemia. This article reviewed the study progress in ApoA-I's gene polymorphism and its relationship with reverse cholesterol transport (RCT).

Objective: According to the relevant principles of blood volume monitoring and monitoring methods, to apply online monitoring data information management in the blood volume monitoring for hemodialysis patients. Methods:through the relevant technical form and its function of monitoring data to study and analyze of treatment parameters of hemodialysis patients described in online blood volume monitor, to achieve data analyzed by using information management system. Results: the blood volume can be visually monitored during the hemodialysis to understand changes in the blood volume of hemodialysis patients, it helps to avoid the occurrence of hypotension and evaluation of patients with dry weights during the hemodialysis. The data can be downloaded, exported, and edited at the same the while fully access to treatment data by effective using of blood volume monitoring data management system (BVMS), in order to achieve data analyzed by using information management system. Conclusion:by understanding the correlation betweenΔBV and blood pressure screen composition can help to speculate the reasons for drop in blood pressure;by combining the examination data can help to control dry weight management, by fully accessing to data can help to manage hemodialysis patient data information management system, and according to patients expression and display of blood volume monitoring to determine the appropriate amount of ultrafiltration, adjust dry weight and develop an appropriate treatment plan.

Long non-coding RNA (lncRNA)is a kind of RNA molecule which is longer than 200 nucleotides and has no capacity of coding proteins.Accumulating evidences have indicated that several lncRNAs,such as HOTAIR,MALAT-1 ,H1 9 and BANCR may promote tumor metastasis by inducing epitheli-al-mesenchymal transition.

Urothelial carcinoma associated antigen 1(UCA1)is a highly bladder cancer-specific long non-coding RNA(lncRNA),and it does not have the function of encoding protein. UCA1 differentially expre-sses in various fetal tissues,but its expression is turned off in most adult tissues. It reactivates during tumori-genesis. Researches indicate that UCA1 may regulate cell proliferation,apoptosis,metastasis and chemoresis-tance of tumors,such as bladder cancer,breast cancer and hepatocellular cancer.

Objective To investigate the efficacy of radiofrequency ablation in the treatment of meniscus injury. Methods 42 cases of damaged meniscus of knee joint were treated with radiofrequency ablation under arthroscopy. Results After 15 to 30 months(mean 25.2 months) follow-up, 38 knees ( 90%) were evaluated as excellent, and 4 (10%) as good. Conclusion Radiofrequency ablation was a safe, simple and effective technology for the treatment of meniscus injury of knee joints.

AIM: To study the curative effect for patients with age related cataract and shallow anterior chamber after phacoemulsification.METHODS: Totally 38 patients (38 eyes) with age related cataract and shallow anterior chamber were selected and divided into two groups according to the depth of the anterior chamber, as mild shallow anterior chamber group (2-2.5mm) 23 eyes, high risk shallow anterior chamber group (<2.0mm) 15 eyes.Thirty-eight patients (38 eyes) with age related cataract with normal anterior chamber were as control group at the same period.All the patients received the operations by the same doctor and were followed up for 3mo.The observed items included visual acuity before and after operations, intraocular pressure, anterior chamber depth, corneal endothelial cell density and complications.RESULTS: There were no significant difference on visual acuity, intraocular pressure and corneal endothelial cell density between the two groups before operations (P>0.05).The visual acuity improved significantly after operation in both groups (P<0.05).Intraocular pressure after operation decreased significantly in both groups (P<0.05).Anterior chamber depth increased significantly after operation in both groups (P<0.05).Corneal endothelial cell density decreased significantly in both groups (P<0.05).There were no significant difference on anterior chamber depth, intraocular pressure and corneal endothelial cell density between the two groups at different time point after operations (P>0.05).Posterior capsular rupture occurred in shallow anterior chamber group in 1 eye, suspensory ligament rupture in 1 eye.Posterior capsular rupture and suspensory ligament rupture occurred none in normal anterior chamber group.Postoperative corneal edema occurred in 10 eyes (26%) in shallow anterior chamber group, which occurred in 3 eyes (8%) in normal anterior chamber group.The difference on the incidence was significant (P <0.05).CONCLUSION: Phacoemulsification should be taken timely for patients with age related cataract and shallow anterior chamber.The postoperative visual acuity can be improved and the anterior chamber depth can increase.The operation is safe and effective for those patients.

Objective To observe the effect of sinomenine on the proliferation of fibroblast-like synoviocytes (FLS) and expression level of MMP-3 secreted by FLS in rheumatoid arthritis in vitro. Methods FLS were obtained by digesting synovial tissues with collagens and were divided into four groups:sinomenine high, middle, low concentration and control group. The proliferation of FLS was assessed by methyl- thiazolyl-tetrazolium (MTT) assay and the mRNA expression of MMP-3 was measured by semi-quantitative RT-PCR respectively after treated by sinomenine. Results The rate of FLS proliferation was significantly reduced in groups treated by sinomenine. Compared with control group, the mRNA expression of MMP-3 markly decreased in sinomenine groups (P

Objective To observe the clinical effect and safety of subanesthetic doses of ketamine and fentanyl assisted regional anesthesia.Methods 90 children received abdominal operation or limbs operation were selected in our hospital.They were randomly divided into A,B and C group with 30 children in each group.The children in group A received sub-anesthetic doses of ketamine and fentanyl in nerve block anesthesia; the children in group B received sub-anesthetic doses of ketamine and fentanyl anesthesia aided;while the children in group C accepted traditional ketamine anesthesia.The indexes of respiratory frequency,mean arterial pressure,heart rate and oxygen saturation and other basic vital signs as well as anesthesia adverse events of situation were compared.Results The respiratory frequency,mean arterial pressure and heart rate in group A and B were lower than those in group C,the difference was statistically significant(all P <0.05),whereas no difference was observed on the oxygen saturation between two groups(P >0.05).The respiratory rate,mean arterial pressure and heart rate in group A and B showed no significant difference (all P > 0.05).In adverse reactions,the muscle relaxants was in good condition in group A and B,no obvious body movement and gastrointestinal adverse events observed either.Group C with muscle relaxants in good condition,but body movement and some gastrointestinal adverse reaction can be observed occasionally.Conclusion Subanesthetic doses of ketamine and fentanyl has good anesthetic effect on regional anesthesia,and can effectively reduce the occurrence of adverse reactions,which is worthy of clinical application.
