Acetabular is an important human joint for weight bearing. Quadrilateral plate is a crucial structure of medial acetabulum with special morphology and important function. Quadrilateral plate fractures are common fracture in acetabulum. Quadrilateral plate fracture is hard to expose and reduction because it is in the medial of acetabulum. At the same time,the bone in the quadrilateral plate is not easy to fixed for thinning bones and adjacent to the articular cavity. The operator should know well about the anatomy and choose the suitable internal fixation. After quadrilateral plate fractures, the femur head maybe displace medially even break into pelvis. That make reduction and treatment always be a challenge. With different kinds of fractures,the efficacy of treatment is not the same. This paper intend to review the relation of anatomic features,approaches, internal fixations, key point of treatment and efficacy.

Objective To investigate the curative effect of arthroscopic treatment for lateral dis-cord meniscus tear in children. Methods The study involved 229 child patients with lateral discord meniscal tear treated arthroscopically from March 1996 to March 2008. There were 133 males and 96 fe-males, at age of (9±3.5) years (range 4-14 years). The treatment methods included meniscus-plasty in 219 patients (including two children with postoperative recurrence), meniscus-plasty-suture in eight and partial meniscectomy in two. The function of the knees was assessed pre-operationally and post-operation-ally by using Lysholm score. Results Of all, 221 patients were followed up for a period of (65±48.9) months (range 5-144 months). The pain and swelling were alleviated, with obvious improvement in range of motion and knee function in all patients six months after operation. There were no complica-tions including intra-articular infection, iatrogenic injury, fibroarthritis or loss of range of motion. Ly-sholm score was (61.85±7.65) points (range 45-73) before operation, which was improved to (95.30±3.50) points (range 87-100 points) six months after operation (t= 26.778, P < 0.01). Conclusion Treatment of lateral discord meniscus tear under arthroscopic guidance in children has the advantages of minor trauma, satisfactory results, can maintain good shape of the meniscus and good func-tion of knee and reduce incidence rate of osteoarthritis.

Objective To investigate the volume of hippocampal formation in normal adult using coronal magnetic resonance imaging. Methods 3D-fSPGR sequence was used to depict the brain in 68 healthy adult. The volume of hippocampus was calculated by drawing the outline of 10 coronal hippocampal formation images acquired equally form posterior border of rostrum corpus callosum to anterior border of the splenium. Data were analysed using the SPSS 17.0 software. Results In the coronal plane images of normal adult brain, the absolute volume of left and right hippocampal formation were 2 319.63-2 610.73 mm3 and 2 447.52-2 749.50 mm3 respectively . The relative volume of left and right hippocampal formation were 2 319 . 87-2 602 . 47 mm 3 and 2 443.96-2 755.89 mm3. There were no correlation between hippocampal volume and age (r = 0.084, P = 0.549. Significant gender differences (t=2.500, P=0.029) were observed between absolute volume of right hippocampal formation in the youth group. There were significant differences in the absolute volume (t = -2.571, P = 0.022), relative volume (t = 2.600, P = 0.021) among the right and left hippocampal formation. Significant absolute volume differences (P = 0.038) were observed between the middle-aged group and the youth group among the hippocampal formation of women. Conclusion No significant differences were observed in age, gender among the hippocampal volume of normal adult, and there was a significant difference between the left and right hippocampal formation volume.

Objective To study the clinical value of 18F-FDG PET/CT in childhood neuroblastoma (NB). Methods 18F-FDG PET/CT was performed in 31 children diagnosed with NB. According to the treatment conditions, patients were divided into pre-therapy group, radiation and chemotherapy group, postoperative group, respectively. The positive rate, sites, and im-age characteristics of the primary lesion and metastasis lesion were analyzed through qualitative and quantitative analysis of the image. Results Twenty-one (67.7%) and fourteen (45.2%) patients were found positive in primary sites by CT and PET respectively. All cases (9/9, 100%) in pre-therapy group were found positive in primary lesions by PET, 3 positive cases (75.0%) in radiation and chemotherapy group and 2 positive cases (11.1%) in postoperative group. Twenty-one patients showed metas-tases (67.7%). Lymph nodes (16 cases) and bone (bone marrow) (13 cases) were the most common sites of metastasis followed by pleura, meninges, liver and retrobulbar inifltration, all of which showed increased FDG uptake. Two patients were found lesions in lungs by CT, but had no FDG uptake. SUVmax of primary lesions was signiifcantly different among pre-therapy, chemotherapy and postoperative group (H=13.89, P=0.001), and pre-therapy group had the highest value. Metastases (lymph nodes, bone and bone marrow, pleura, liver and meninges) in pre-therapy group had high SUVmax. Conclusions NB primary tumors are characterized by the increased FDG metabolism. PET can fully detect the distribution of NB metastases in whole body. Except the pulmonary metastasis, metastases in other positions show increased FDG uptake. PET has potential role in evaluating the efifcacy of radiation and chemotherapy, and identifying postoperative residual or recurrence.

Objective To study the level of serum apolipoprotein M and its disease activity index in patients with SLE.Meth-ods 65 cases of systemic lupus erythematosus patients in Shiyan City Renmin Hospital from January 2013 to December 2015 were selected.In addition,female workers 20 people as control group.Tested the level of serum lipids,Apo,CRP and ESR.Compared the expression level with Apo M and Apo A1 ,and Apo B and the degree of disease activity.Results Activi-ty group and Apo A1 ,HDL,TC,remission group,Apo and M were lower than the control group,the difference was statisti-cally significant (P<0.01).Active group,remission group LDL and Apo B was higher than the control group,and the difference was statistically significant (P<0.01).Active group and remission group TG was higher than the control group, but no significant significant differences (F=0.061,P=0.937).Apo A1 and total cholesterol,high density lipoprotein, smooth protein was positively correlated (P<0.05),and ESR was negatively correlated with the 24h urinary protein (P<0.05).Apo B was positively correlated with triglyceride,total cholesterol,and low density lipoprotein (P<0.05).Apo M and triglyceride,total cholesterol,low density lipoprotein cholesterol,high density lipoprotein,albumin was significantly posi-tively correlated,and ESR was negatively correlated with anti ds-DNA antibody (P<0.05).Conclusion The level of Apo M was significantly lower in SLE patients which showed a significant positive correlation with triglyceride,total cholesterol, low density lipoprotein,high density lipoprotein and albumin.And showed a negatively correlated with anti ds-DNA antibody and ESR.Disease activity index of Apo M is larger.

AIM: To establish a method of determining genpioside,baicalin and berberine in Gonglao Quhuo Tablets(Caulis Mahoniae,Cortex Phellodendri Chinensis,Radix Scutellariae,etc). METHODS: The mobile phase composed of A acetonitrile,B acetonitrile and 0.5% triethylamine(Ph3.1)(10∶90).The flow rate was 1.0 mL/min with the wavelength at 254 nm. RESULTS:The calibration curves were linear in the ranges of 3.22-206 ?g/mL(r=0.999 9) for genpioside,2.95-186 ?g/mL(r=0.999 9) for baicalin and 1.64-104 ?g/mL(r=0.999 9) for berberine hydrochloride,respectively.The average recoveries were not less than 98.4%. CONCLUSION: This HPLC method is convenient,rapid,accurate and could be used for quality control of production of Gonglao Quhuo Tablets.
