Effect of local blocking on osteoarthritis of the hip

Objective:To provide an effective treatment for the Osteoarthritis of the hip by observing the effect of local blocking of HongHua injection on relieving hip pain.Methods:Methods from June 2015 to May 2017,60 patients with Osteoarthritis of the hip in Wangjing Hospital of Chinese Academy of Sciences were randomly divided into treatment group and control group,30 cases in each group.The treatment group was given local blockingof HongHua injection treatment,control group using Compound Betamethasone Injection local closed treatment.Visual analogue scale(VAS)score,pericoxal local tenderness and hip mobility were used to evaluate the therapeutic effect.The therapeutic indicators at six different time points after 1 days,3 days,7 days,2 weeks and 1 months after treatment were compared.Results:All the 60 cases completed treatment and follow-up,and there were no cases of abscission.There was no significant difference in gender,age,etiology,classification and Harris score before treatment between the two groups(P>0.05),which was comparable.VAS score:There was no significant difference between the two groups on the 1st,3rd,7th and 2nd week after treatment(P>0.05),but the treatment group was lower than the control group on the 1st month after treatment(P<0.01).Hip joint activity:There was no significant difference in hip joint activity between the two groups 1 day,3 days,7 days,2 weeks and 1 month after treatment(P>0.05).Local tenderness around hip:The efficacy of the midpoint inguinal tenderness score was similar between the two groups at 1 day,7 days,2 weeks and 1 month after treatment(P>0.05);the treatment group was lower than the control group at 3 days after treatment(P<0.01);the adductor starting tenderness score had no significant difference at 1 day,3 days,7 days,2 weeks and 1 month after treatment(P>0.05).Conclusion:Local blockingof HongHua injection is effective and effective in treating hip pain in Osteoarthritis of the hip.The HongHua injection has many advantages,such as good safety and wide indications.It is worthy of further clinical application.

Classification of Gastric Lesions Using Gabor Block Local Binary Patterns

The identification of cancer tissues in Gastroenterology imaging poses novel challenges to the computer vision community in designing generic decision support systems.This generic nature demands the image descriptors to be invariant to illumination gradients,scaling,homogeneous illumination,and rotation.In this article,we devise a novel feature extraction methodology,which explores the effectiveness of Gabor filters coupled with Block Local Binary Patterns in designing such descriptors.We effectively exploit the illumination invariance properties of Block Local Binary Patterns and the inherent capability of convolutional neural networks to construct novel rotation,scale and illumination invariant features.The invariance characteristics of the proposed Gabor Block Local Binary Patterns(GBLBP)are demonstrated using a publicly available texture dataset.We use the proposed feature extraction methodology to extract texture features from Chromoendoscopy(CH)images for the classification of cancer lesions.The proposed feature set is later used in conjuncture with convolutional neural networks to classify the CH images.The proposed convolutional neural network is a shallow network comprising of fewer parameters in contrast to other state-of-the-art networks exhibiting millions of parameters required for effective training.The obtained results reveal that the proposed GBLBP performs favorably to several other state-of-the-art methods including both hand crafted and convolutional neural networks-based features.

Hyaluronidase in sub-Tenon's anesthesia for phacoemulsification,a double-blind randomized clinical trial

AIM:To investigate the effect of hyaluronidase use on the quality of sub-Tenon's anaesthesia for phacoemulsification.· METHODS:This was a randomized,double-blind clinical trial which was conducted at Nikookari Eye Hospital for 5 months.Forty-two eyes of candidates for phacoemulsification under sub-Tenon's anaesthesia were randomly allocated to two equal groups and received either 2 mL of lidocaine 2% solution with(LH),or without(L) addition of hyaluronidase(150IU/mL).Akinesia was assessed 15 minutes after sub-Tenon's injection.Patients and surgeon's satisfaction,as well as the postoperative pain(the visual analogue scale,VAS) were investigated after operation.The contingency tables(including the Chi-square or Fisher's exact tests,when appropriate) and parametric analysis(the independent samples t test) were used for statistical analysis.· RESULTS:Complete akinesia(33.3% vs 4.8%,P =0.04),as well as the patients(85.7% vs 57.1%,P =0.04)and surgeon's satisfaction(87.5% vs 52.4%,P =0.02) were significantly more frequent in LH than in L group.The mean VAS was significantly lower in the same group(1.90±1.45 vs 3.00±1.55,P =0.04).· CONCLUSION:Addition of hyaluronidase to lidocaine solution for sub-Tenon's anesthesia significantly improves the ocular akinesia,enhances the intra-operative patients and surgeons' satisfaction,and attenuates the postoperative pain.·

EFFECT OF LOCAL BASIC FLOW STRUCTURE PATTERN IN FORMATION OF BLOCKING HIGHS

The effect of local basic flow structure pattern(BFSP)on a blocking high formation is investigated within the framework of forced dissipation KDV dynamics.The zonal and meridional positions of the high's center excited by a heat source depend on the BFSP selected.

PRODUCT IMAGE RETRIEVAL BASED ON CO-FEATURES OF THE OBJECT

In this paper, we propose a product image retrieval method based on the object contour corners, image texture and color. The product image mainly highlights the object and its background is very simple. According to these characteristics, we represent the object using its contour, and detect the corners of contour to reduce the number of pixels. Every corner is described using its approximate curvature based on distance. In addition, the Block Difference of Inverse Probabilities (BDIP) and Block Variation of Local Correlation (BVLC) texture features and color moment are extracted from image's HIS color space. Finally, dynamic time warping method is used to match features with different length. In order to demonstrate the effect of the proposed method, we carry out experiments in Mi-crosoft product image database, and compare it with other feature descriptors. The retrieval precision and recall curves show that our method is feasible.
