OBJECTIVETo study effects of autogenous femoral head bone grafting combined with total hip replacement for the treatment of old center dislocation of hip joint, and to evaluate the superiority of acetabular defect reconstruction with autogenous bone.

METHODSFrom March 2008 to December 2013, 16 patients (16 hips) with old center dislocation of hip joint were treated with autologous bone graft combined with total hip replacement. There were 11 males and 5 females, ranging in age from 41 to 72 years old, with an average of 56.3 years old. The duration of the disease ranged from 3.6 to 37.2 years. Twelve patients had injuries caused by traffic accidents and 4 patients were caused by falling down. The hip joint pain at the first month after operation, Harris score and hip joint movement of all patients were observed by using electronic case follow-up system.

RESULTSAll the patients were followed up, and the duration ranged from 11 to 78 months, with an average of 27.3 months. The postoperative hip joint movement of (56.2±23.4)° VAS 86.3±7.2 and Harris score 32.6±12.6 were all better than preoperative (181.8±17.6)°, 11.1±2.6 and 86.3±7.2. The joint pain was reduced and the function limitation was improved after operation, and the prosthesis position was good.

CONCLUSIONWhen the autologous femoral head bone grafting combined with total hip arthroplasty is used to treat old hip central dislocation, the initial and long-term stability of acetabular bone grafting is good, and the technique can avoid allogeneic bone complications, bone source rationally and reduce the economic burden of patients.

Objective To explore the dynamic changes of abdominal and peripheral arteries in the patients with familial hypercholesterolemia(FH). Methods The intima-media thickness(IMT), stenotic degree and hemodynamics change of arteries were measured by ultrasonography in three children in 3 FH pedigrees. Results The plaques number and IMT of carotid and femoral arteries in the patients with FH significantly increased. The IMT of vertebral artery, subclavein artery, abdominal aorta, renal artery, illac artery and popliteal artery did not obviously changed. Conclusion Noninvasive vascular ultrasound was a preferred imaging technique to follow up the vascular change in the patients with FH.

Fibrosis is a pathological process characterized by tissue scars and can occur in many organs of the human body. Organ fibrosis is manifested by increased fibrous connective tissue and reduced parenchymal cells in organ tissues, which can lead to destruction of organ structures and reduced function, which seriously endangers human health. Current strategies for treating organ fibrosis include: blocking the transforming growth factor-β1 (TGF-β1)/Smad signaling pathway, anti-inflammatory, regulating the sphingosine kinase 1/sphingosine-1-phosphate (SK1/S1P) signaling pathway, antagonizing vasoactive peptide receptors, enzyme inhibitors, kinase inhibitors, inhibitors of cellular signaling pathway, regulation of metabolic pathways, and mesenchymal stem cell therapy. In the review, the treatment strategies for organ fibrosis and the latest developments in the research of anti-organ fibrosis drugs are summarized to provide a reference for the development of anti-organ fibrosis drugs.

BACKGROUND:It remains controversial in term of efficacy for the lightweight mesh and heavyweight mesh in inguinal hernia repair.
OBJECTIVE:To compare the clinical therapeutic effects of lightweight mesh and heavyweight mesh in open methods of inguinal hernia repair with Meta-analysis.
METHODS:Comprehensive electronic search strategies were developed using the fol owing electronic databases:PubMed, Cochrane Library, EMBASE, Medline, Ovid, CNKI, VIP, Wanfang and FMJS. The Literature published before February 2013 was searched. The randomized control ed trials about comparing lightweight mesh and heavyweight mesh in open methods of inguinal hernia repair were included. A data-extraction sheet was developed based on the preset standards. The data from eligible studies were pooled using RevMan5.1 software through Meta-analysis.
RESULTS AND CONCLUSION:Eighteen trials with a total of 4 450 hernias met the inclusion criteria. The meta-analysis showed that there was a statistical difference between lightweight mesh group and the heavyweight mesh group on short-term pain [odd ratio (OR)=0.57, 95%confidence interval (CI) (0.43, 0.74), P<0.05] and a reduced risk of developing foreign body sensations [OR=0.49, 95%CI (0.35, 0.69), P<0.05]. No significant differences were found between the two groups in recurrence rate, testicular atrophy, seroma, hematoma, wound infection, urine retention (P>0.5). According to limited evidence, there are some findings as fol ows:the lightweight mesh is of feasibility, safety and effectiveness for inguinal hernia repair. Because of the limits of sample and quality, more large-sample and high-quality trials are required to make a definite clinical evidence to use lightweight mesh for inguinal hernia repair.

Objective To evaluate the efficacy and clinical feasibility of the computer-assisted full plan- ning system for tibial fracture treatment with intramedullary nailing.Methods After analyzing the functional structure and operative procedures of the system,nine plastic tibia and 12 cadaver lower limbs were used for image mosaicing based on C-arm (PHILIPS BV Libra) fluoroscopic images in the operation room to assess the correctness of the mosaicing and planning algorithms.The plastic tibial model was used for analysis of the mosaicing precision.The cadaver tibial bone was used for reduction experiment with the reduction mechanism to analyze the operation feasi- bility.Results Only 7 to 10 [fluoroscopy time:(19.75?0.61)s] valid C-ann projection images were needed to produce a long bone panorama of the lower limb.The total time for image acquisition and mosaicing was within (4.17?0.86)minutes and the mosaicing precision in the plastic tibial model was (1.26?0.76)mm.The opera- tion of the reduction mechanism was very simple and could be controlled by a surgeon automatically or free of hand. An integrated reduction strategy could be produced for rough positioning in general and elaborate operations in de- tails.Conclusion The computer-assisted full planning system can be used for anatomical analysis based on the C-arm panorama,full surgical planning,virtual simulation,selection of proper intramedullary nails and fracture reduction in treatment of long bone fractures.

Objective To evaluate contrast-enhanced ultrasonography (CEUS) in diagnosis of small hepatocellular carcinoma (SHCC) ( ≤ 2. 0 cm) with liver cirrhosis after contrast-enhanced CT (CECT) examination. Methods Forty five patients with liver cirrhosis received CECT and CEUS examinations before operation or needle biopsy and the diagnosis was confirmed by pathological examination.CEUS and CECT findings of 51 liver space-occupying lesions from 45 patients were retrospectively analyzed.Results Among all 51 lesions detected CEUS and CECT found 49 and 35, respectively. The typical characteristics of SHCC were "fast-in and fast-out" and "fast-in and slow-out". The sensitivity of CEUS and CECT in diagnosis of SHCC was 88. 9% (32/36) and 69. 4 % (25/36) respectively ( x2 = 3. 02, P =0. 08);the diagnostic accuracy was 84. 3 % (43/51 ) and 56. 9% (29/51 ) respectively ( x2 = 1.46, P =0. 22). Among 16 lesions missed by CECT, 12 were detected by CEUS. Conclusions CEUS and CECT show the similar diagnostic rate for typical SHCC ,however, CEUS is more sensitive for atypical lesions. With high time resolution, CEUS have advantages for follow-up study of benign liver lesions.

Objective To observe the external morphology of Lepidoglyphus destructor hypopus under an optical microscope. Methods The samples were collected in a store of Chinese medicinal herbs in Huainan City in September,2016,the L. de-structor and the hypopus were isolated,and then made of slide specimens. The slide samples were prepared and observed under an optical microscope. Results The L. destructor hypopus and protonymph were found. The inactive hypopus was oval in shape, the feet were not well-developed,there was a distinct transverse seam on its back,and there were 2 pairs of genital sensory or-gans. Conclusion The optical microscopy shows the morphological characteristics of L. destructor hypopus,which can provide the basis for the biological classification and the prevention.
