Objective To investigate the effects of radiofrequency thermocoagulation in relieving refractory pain of knee osteoarthritis in older patients.Methods A total of 18 patients with refractory pain of knee osteoarthritis were under treatment of radiofrequency thermocoagulation to denervation and compared to 20 patients with refractory pain of knee osteoarthritis which were under treatment of arthroscopy combined with compound betamethasone (control group).The Oxford knee score and visual analogue scale were used to evaluate the clinical effects before operation,at 1 week,4 weeks and 12 weeks after operation.Results There were significant decreases in both groups after operation than before operation(Foxford ＝4.12,3.98,FVAS ＝3.98,4.11,both P＜0.05),but there were no statistics differences between radiofrequency thermocoagulation group and control group at 1 week,4 weeks and 12 weeks after operation(toxford ＝ 1.215,1.426; tVAS＝1.319,1.123,0.867,P＞0.05).Conclusions The treatment of radiofrequency thermocoagulation is a minimally invasive method,which can relieve refractory pain of knee osteoarthritis in middle and older patients and recover knee function effectively.

Objective To construct the eukaryotic plasmid expression vector mediated short hairpin RNA(shRNA) interference targeting TLR4 gene,and transfect it into pancreatic adenocarcinoma cell line PANC1,then screen stably transfected clonal cell line.Methods Three shRNA interference expression plasmid vectors targeting the TLR4 gene were constructed,named TLR4-1,TLR4-2,TLR4-3.The shRNA plasmid with highest inhibitory efficiency was selected and transfected into PANC1 cells with liposome.The silencing efficiency and transfection efficiency of TLR4-shRNA was assayed with real-time quantitative PCR and flow cytometry analysis.Monoclonal cell with stable transfection of TLR4-shRNA were selected by geneticin 418 (C418) and limiting dilution analysis.Results Transient transfection efficiency of PANC1 was (46.72 ±5.06) ％.TLR4 mRNA expressions were 0.025 ± 0.004,0.027 ± 0.003,0.019 ± 0.006in cells transfected with TLR4-1,TLR4-2,TLR4-3,respectively,which were significantly lower than that in untransfected group (0.061 ±0.018) and negative control group (0.057 ±0.015,P ＜0.05).The transfection efficiency of TLR4-3 vector in stably transfected clones [(82.79 ±8.16)％] was significantly higher than that of transient transfection (P =0.001 ).The expression of TLR4 mRNA was decreased to 0.010 ± 0.002,which was significantly lower than that of transient transfection ( P =0.001 ).The expression of TLR4 protein was (0.54±0.32) ％,which was significantly lower than that of untransfected cells [( 87.42 ± 5.00 ) ％] and that of negative control [(82.9±5.00)％,P =0.000].Conclusions Stable transfection PANC1 cell lines with TLR4 gene silencing are successfully identified.

Objective To investigate the effects of intra-articular injection of ropivacaine plus compound betamethasone after arthroscopic debridement for knee osteoarthritis.Methods A total of 164 patients with knee osteoarthritis after arthroscopic debridement were randomly divided into three groups:combination group (n=62) treated by 2 ml sodium hyaluronate and 0.75％ ropivacaine of 5 ml plus 1 ml compound betamethasone,compound betamethasone group (n=54) by 2 ml sodium hyaluronate and 1 ml compound betamethasone,control group (n=48) by simply sodium hyaluronate.The Lequesne Index was used to evaluate the clinical effects before and 1 week,6 weeks and 12 weeks after operation.All patients received at least 12 weeks follow-up Results According to Lequesne Index score criteria,a significant decrease was found in all groups before versus after operation(P＜0.05).The clinical effects in combination group and compound betamethasone group were more improved as compared with control group at 1,6 and 12 weeks after operation (P＜0.05).The effect in combination group was better than compound betamethasone group at 1 and 6 weeks after operation,but not at 12 weeks (P＞0.05).Conclusions The intra-articular injection of ropivacaine plus compound betamethasone after arthroscopic debridement is a good method for relieving pain and improving the knee function.

OBJECTIVE:To investigate the application of knowledge management in pharmaceutical department of hos-pitals.MEHTODS:Different models of knowledge management in the pharmaceutical department of our hospital were sum-marized in recent years.RESULTS:The knowledge management model in our pharmaceutical department has been shaped fundamentally.CONCLUSION:Coping capacity and creativity of pharmaceutical department have been strengthened by knowledge management.

OBJECTIVE:To study the effects of shuanbiling on mesenteric microcirculation in rat.METHODS:Changes of blood flow velocity,blood flow states and blood vessel diameter of mesentery were observed by microvideo frame to frame30minutes after iv of shuanbiling45,90,180IU/kg respectly.RESULTS:Low,mid,high doses of shuanbiling groups significantly increased the blood flow velocity,which increased by24.25%,26.34%,and25.88%respectively in;The blood vessel diame-ters increased by21.37%,27.13%,and28.80%respectively for arterioles;and6.70%,9.31%,12.95%for venules.Blood flow states were also improved significantly.CONCLUSION:Shuanbiling could improve the mesenteric microcirculation in rat.

The method of flying through the air is a qi-promoting and qi-circulating technique commonly used in clinical acupuncture. It includes four methods: the blue dragon wagging its tail, the white tiger shaking its head, the green turtle probing the cave and the red phoenix winging to the source and functions to circulate bodily meridian qi. The method of flying through the air was firstrecorded in Golden needle Fu. Later and modern doctors developed it on the basis of Golden needle Fu. This article straightens up the historical origin and development of four methods of flying through the air.

Objective: To establish a risk prediction model and scoring system in patients with side branch (SB) occlusion during coronary bifurcation intervention. Methods: A total of 7007 consecutive patients who received percutanenous coronary intervention (PCI) in our hospital from 2012-02 to 2012-07 were recruited and 1545 patients (with 1601 bifurcation lesions) treated by single stent technique or main vessel stenting ifrst strategy were selected for our study. According to weather SB occlusion occurred during operation, the lesions were divided into 2 groups: Non-SB occlusion group,n=1431 and SB occlusion group,n=114. The data set of the ifrst 1200/1601 lesions by time sequence, was used for establishing the risk model and scoring system, the data set of rest 401 lesions was used for model validation. Results: The modeling data set presented that the relationship between pre-operative main vessel plaque and the position of branch vessel, the main blood vessel pre-stenting TIMI grade, the stenosis degree of pre-operative bifurcation nucleus, the angle of pre-operative bifurcation and the ratio of pre-senting stenosis degree of branch diameter and pre-operative main vessel to branch vessel diameter were the independent risk factors for branch occlusion. The risk model ROC=0.80, 95% CI 0.75-0.85, Hosmer-Lemeshow HLP=1.00; the scoring system ROC=0.76, 95% CI 0.71-0.82, HLP=0.12. The validation data set ROC=0.81, 95% CI 0.73-0.89, HLP=0.77; the scoring system ROC=0.77, 95% CI 0.69-0.86, HLP=0.58. The quartile integration of both data sets indicated that the patients with the integration score ≥ 10 had the higher risk for SB occlusion than those with integration score < 10 during the operation,P<0.001. Conclusion: Our research developed a simple and user-friendly system, it may distinguish the patients with high risk of SB occlusion during bifurcation intervention by quantitative stratiifcation of coronary angiographic imaging.
