Objective To determine the incidence of clinically common acute avulsions of the popliteus tendon (PT) and the lateral collateral ligament (LCL) of the femur (peel-off lesion) in knees with multiple injured ligaments.Methods A retrospective review of 48 acute grade 3 posterolateral corner (PLC) knee surgeries was conducted.All office evaluations were reviewed to determine the demographic data,tear description,preoperative MRI examination,physical examination under anesthesia,intraoperative arthroscopic findings and surgical techniques.Results In total,19 patients were surgically verified as having femoral peel-off lesions as a portion of a series of multiple pathologic findings.Tear patterns were typically categorized into 3 patterns:isolated PT tear (pattern 1,4 patients),combined PT and LCL tears (pattern 2,8 patients) and complex tears (associated intrasubstance and/or fibular-based injuries,pattern 3,7 patients).Seventeen of the 19 patients underwent preoperative MRI examination,which demonstrated conclusive signs of femoral insertion separation and discontinuity in 13 patients (76%) and inconclusive signs of femoral insertion separation.Examination under anesthesia (EUA) revealed that for the 4 patients with pattern 1 injuries,the tibial external rotation increases were all greater than 10°.For the 15 patients with pattern 2 and 3 injuries,the yarus instability was as follows:grade 3 in 8 patients,grade 2 in 2,grade 1 in 1,and negative in 4.External rotation increases were greater than 10° in 12 patients and less than 10° in 3.Seventeen of the 19 patients were inspected with an arthroscope prior to PLC surgery:of these patients,94% had acute avulsion findings and positive lateral gutter drive-through sign;8 patients were repaired with recess or reattachment procedures;6 patients were primarily reconstructed;4 patients were treated with combined repair and reconstruction;and 1 patient was left untreated for secondary reconstruction due to priority repair for concurrent patellar tendon rupture.Conclusion For adequate clinical identification,we recommend a comprehensive diagnostic protocol,including MRI,physical examination and arthroscopic inspection,to avoid underdiagnosis of the lesion in multiple-ligament injured knees.The lateral gutter arthroscopic evaluation is particularly sensitive for detecting the lesion.

PurposeTo discuss the imaging characteristics and prognostic value of 18F-FDG PET/CT in primary osteosarcoma.Materials and MethodsThirty patients with osteosarcoma confirmed by pathology were enrolled in the study. The imaging characteristics of preoperative whole body18F-FDG PET/CT were analyzed retrospectively. The max standard uptake values (SUVmax) and CT values of lesions were obtained, and tumor volume was calculated; disease-free survival duration was calculated according to the reoccurrence and metastasis of tumor and death; the SUVmax of different components was compared, and the SUVmax in each position was analyzed in terms of the correlation with the corresponding CT value and factors influencing the prognosis.ResultsCT images showed that 28 patients with primary osteosarcoma had bone destruction, 20 had ground-glass or cotton-like neoplastic bone, 24 with soft tissue mass and 16 with periosteal reaction had increased18F-FDG uptake, and 17 with high-density neopalstic bone had low 18F-FDG uptake. The SUVmax of high-density neoplastic bone was significantly lower than that of bone destruction, low-density neoplastic bone and soft tissue mass (F=5.196, P<0.01). There was a weak negative correlation between the SUVmax of various parts such as bone destruction, low-density neoplastic bone, high-density neoplastic bone and soft tissue mass and the corresponding CT value (r=-0.315,P<0.01). The disease free survival time was (36.9±14.9) months. The Kaplan-Meier curve analysis showed that the disease free survival time was longer in patients with SUVmax≥9 than in those with SUVmax<9 (χ2=0.696,P<0.05). The Cox regression analysis presented that SUVmax had independent prognostic value (Wald=4.213,P<0.05).Conclusion18F-FDG PET/CT has advantages in presenting the anatomical structure changes and metabolic changes in primary osteosarcoma. Combined with semi-quantitative analysis of SUVmax, PET/CT can be helpful in finding out the highest biological activity part from the complex tumor structures. Neoplastic bone with low density/high metabolism suggests high malignancy. The higher the SUVmax, the worse the prognosis is in patients with primary osteosarcoma.

Objective To investigate the effects of different culture media and pretreatment methods on the results of matrix-assisted laser desorption ionization time-of-flight mass spectrometry(MALDI-TOF MS) for the identification of Vibrio parahaemolyticus,and then provide the optimal conditions.Methods Forty strains of Vibrio parahaemolyticus were collected,and subcultured with the blood agar plate,thiosulfate citrate bile salts sucrose(TCBS) agar plate and double wash agar plate,respectively.The pretreatment methods before mass spectrometry included the smear method,extension method and extraction method.The effects of different culture media and pretreatment methods on the results of MALDI-TOF MS for the identification of Vibrio parahaemolyticus were analyzed by the logistics regression model and Chi-square test of SAS software.Results The detection rate of Vibrio parahaemolyticus was the highest in the combination of blood agar plate with the extraction method(genus level:100％;species level:67.5％),followed by the combination of double wash agar plate with the extraction method(genus level:70％;species level:37.5％).For the genus identification level of Vibrio parahaemolyticus,when the pretreatment method was the same,different culture media produced significantly different detection rates(P ＜ 0.01).However,when the culture medium was the same,there was no significant difference in detection rates for different pretreatment methods (P ＞ 0.05).The odd ratios (OR) of the smear method and extention method relative to the extraction method were 0.66 and 0.95,respectively,and there was no significant difference in detection rates for them(P ＞ 0.05),while the ORs of the TCBS agar plate and double wash agar plate relative to blood agar plate were 0.06 and 0.10,respectively,and there was significant difference in detection rates for them(P ＜0.05).The logistic regression equation was Y=2.95-0.41a-0.05b-2.83c-2.83d(a:smear method;b:extension method;c:TCBS agar plate;d:double wash agar plate).For the species identification level of Vibrio parahaemolyticus,when the extension method or the extraction method was used,different culture media produced significantly different detection rates(P ＜ 0.05).When the blood agar plate was used,different pretreatment methods also produced significantly different detection rates(P ＜ 0.01).The ORs of the smear method and extention method relative to the extraction method were 0.32 and 0.55,respectively,and there was significant difference in detection rates for them (P ＜ 0.05),while the ORs of the TCBS agar plate and double wash agar plate relative to blood agar plate were 0.18 and 0.49,respectively,and there was significant difference in detection rates for them(P ＜0.05).The logistic regression equation was Y =0.20-1.15a-0.61b-1.72c-1.72d(a:smear method;b:extension method;c:TCBS agar plate;d:double wash agar plate).Conclusion For improving the detection rate of Vibrio parahaemolyticus by MALDI-TOF MS,the selection of appropriate culture medium is more important than that of the pretreatment method.It is recommended that the extraction method may be as a conventional pretreatment method,and that the optimal medium is the blood agar plate,followed by the double wash agar plate and TCBS agar plate.

Objective To detect the expression of MAGE-A9 in human hepatocellular carcinoma (HCC), and to investigate the association between expression of MAGE-A9 and the clinicopathological characteristics of HCC.Methods Reverse transcription-polymerase chain reaction (RT-PCR), one-step quantitative-PCR (qPCR) and immunohistochemistry (IHC) methods were performed to characterize the expression of MAGE-A9 in HCC cell lines and tissues.Kaplan-Meier survival analysis and Cox regression were employed to evaluate the prognosis of 100 HCC patients.Results The expression of MAGE-A9 mRNA in HCC (4.44±0.342) was significantly higher than that in non-cancerous cells and tissues (1.73±0.178) (P ＜ 0.05).The expression level of the MAGE-A9 protein in HCC was related to the pathological grade (P =0.003), portal vein invasion (P =0.001), distant metastasis (P =0.022) and TNM stage (P =0.005).Cox regression analysis revealed that MAGE-A9 expression is an independent prognostic factor for disease-free survival (P =0.006) and overall survival (P =0.022).Conclusion MAGE-A9 is a valuable prognostic biomarker for HCC patients, and its high expression suggests unfavorable survival outcomes in HCC patients.

Objective To explore the methylation status of Rap1 GTPase activating protein (Rap1GAP) promoter in colon cancer, and to provide the oretical basis and research direction for the early diagnosis, targeted therapy, anti-multidrug resistance of colon cancer and so on. Methods The paraffin embedded specimens of 33 patients with colonic adenocarcinoma diagnosed by pathology were analyzed from Department of Pathology of Xinzhou City People′s Hospital from January 2010 to September 2014, including 19 males and 14 females, and aged 41-72 years old. The paraffin embedded specimens of 16 patients with colonic adenoma were enrolled, including 9 males and 7 females, and aged 34-58 years old. 13 normal tissues from the tumor distal margin (from the tumor > 15 cm) were selected. Quantitative methylation specific PCR (q-MSP) was applied to detect methylation level of Rap1GAP gene promoter. The methylation level differences of Rap1GAP gene promoter region among 3 groups or between different clinicopathologic factor subgroups were compared. Results The methylation rates [median (interquartile range)] of Rap1GAP promoter were 65.43 % (50.35 %), 21.37 % (8.39 %) and 17.43 % (15.71 %) in colonic adenocarcinoma group, colonic adenoma group and adjacent normal tissue group, respectively. The methylation rate of colonic adenocarcinoma group was significantly higher than that of colon adenoma group or that of adjacent normal tissue group (P< 0.05). The methylation rates of Rap1GAP promoter in colonic adenocarcinoma were not correlation with age, sex, differentiation and the stage of TNM [ male vs. female: 42.74 % (70.44 %) vs. 21.98%(80.00%);≤60yearsoldvs.>60yearsold:36.26%(62.62%)and26.23%(76.42 %);well-differentiated vs. moderately/poorly-differentiated: 21.98 % (40.32 %) vs. 42.74 % (74.20 %); TNM Ⅰ-Ⅱ vsⅢ-Ⅳ: 25.31 % (48.27 %) vs. 36.26 % (75.55 %); all P> 0.05]. Conclusion The methylation status of RAP1GAP promoter maybe associate with genesis and development of colon cancer, which might be used as a target for early diagnose of colon cancer.
