Objective To analyze the characteristics of military training injury caused by distal femoral fractures that used reverse interlocking intramedullary nail(retrograte nails) and condylar plate to fix,and then compare the clinical treatment effects.Methods Retrospective analysis of clinical information of 30 cases,14 cases were treated with reverse interlocking intramedullary nail(reverse nail group) and 16 cases with condyle plate fixation(condyle plate group),all the cases were followed up for 12～20 months to compare the treatment effect and complications.Results According to Merchan criteria with clinical evaluation of knee function,the rate of good and excellent was 85.7% in the reverse interlocking in-tramedullary nail group,68.7%(P

Objective To investigate the diagnostic value and clinical implications of low hemoglobin density(LHD%)in the pa-tients with cervical carcinoma complicating iron deficiency anemia(IDA).Methods The iron metabolism indexes and whole blood cell parameters were detected in 148 patients with cervical carcinomas.LHD% was calculated.The results were compared with that in the healthy group and the hysteromyoma complicating IDA group.Results LHD% was(63 ±30)% in the cervical carcinoma complicating IDA group and(32±15)% in the cervical carcinoma complicating iron deficient erythropoiesis(IDE)group,which were higher than(7±6)% in the healthy group,(22 ±21)% in the cervical carcinoma non-iron deficiency group and(16 ±10)% in the cervical carcinoma non-anemia group(P <0.05 ).And which had no statistical difference between the hysteromyoma complicating IDA group and the cervical carcinoma complicating IDA group(P >0.05 ).Conclusion The new RBC parameter LHD% has the reference value in the diagnosis of cervical carcinoma complicating IDA.The LHD% increase may prompt cervical carcinoma com-plicating IDA.

A 35-year-old woman patient,complained of intermittent pain in the left flank for a week.Abdominal ultrasound and computed tomography scan revealed a left renal mass.Nephrectomy was performed,and a final diagnosis of adult Wilms' tumor was made based on histopathology and immunohistology.Chemotherapy was conducted for 4 times with dactinomycin D,vincristine and doxorubicin after surgery.At the time of the last recheck,the patient was alive with no evidence of disease.Adult Wilms' tumor is the exceptional malignant renal tumor.Only 1%-2% of Wilms' tumor is diagnosed in adult patients.Because of unspecific tumor symptoms in adults,the diagnosis is frequently made by histology.The diagnosis of adult Wilms' tumor is difficult to make preoperatively because diagnostic imaging only confirms the presence of a renal mass.Stage and histology are the clinical factors guiding the selection of postsurgical treatment and prognosis.Having retrospected 6 cases of adult Wilms' tumor between 1950 and 2007 and reviewed related reports,we conclude that the proper strategies of adjuvant treatment as applied to childhood Wilms' tumor patients after surgery can conspicuously improve the outcome in adult patients.

In this study, in vitro chemosensitivity testing was conducted on primary cultured breast cancer cells from 96 patients with breast cancer, and the results showed that the cells from a few patients with primary breast cancer developed multidrug resistance (MDR) prior to the first chemotherapy exposure. All the cells from the recurrent cancer patients had MDR. The findings suggested that patients having MDR would benefit from high-dose chemotherapy (HDC) regimens. In vitro chemosensitivity screening, which was aimed at improving the therapeutic efficacy and minimizing side effects, helps in choosing individualized treatment for breast cancer.

Teaching reform is the strong requirement of the times and social development.Immunology department inTaishan Medical College integrated teaching and a variety of extra-curricular teaching,broke the constraints of traditional teaching model in time and space,played the leading role of teachers and inspired students' independent learning,thus improving the teaching effectiveness in immunology.

To obtain active hFKBP52 protein for screening novel neu rotrophic drugs. Semi-nested and overlap PCR and affinity chromatography were u sed. hFKBP52 gene was cloned successfully from human fetal brain cDNA library, a nd then highly expressed (about 30%) as fusion protein in pET28a(+) vector syste m. The recombinant protein was purified as one band on SDS-PAGE. The purified h FKBP52 showed peptidyl-prolyl cis-trans isomerase (PPIase) activity, simil ar to the wild type.

Objective To validate the Partin table 1997,2001 and 2007 for their accuracy in predicting pathologic stage in Chinese prostate cancer patients.Methods From January 1997 to June 2007,109 consecutive patients with clinically localized prostate carcinoma underwent open retropubic or laparoscopic radical prostatectomies and met all inclusion criteria well enrolled.Receiver operating characteristic(ROC)analysis was performed tO test the predictive accuracy of organ confined disease (0CD),extraprostatic extension(EPE),seminal vesicle involvement(SVI)and lymph node involvement(LNI). Results OCD,EPE,SVl and LNl were noted in 70%,17%,13%and 0%of cases respectively.The area under curve(AUC)of ROC for Partin table 1997 was 0.727,0.654 and 0.811for 0CD.EPE and SVl respectively,and was 0.693,0.633 and 0.835 for Partin table 2001 and 0.669.0.611 and 0.778 for Partin table 2007.Conclusions Partin tables 1997,2001 and 2007 are able to accurately predict the pathologic feature of seminal vesicle involvement.However,only Partin table 1997 can more accurately predict organ confined disease in this external validation for Chinese patients.

Objective MiR-375 is lowly expressed in esophageal squamous cancer cells and the downstream target gene of miR-375 remains unclear .This paper discusses the role of miR-375 in regulating the expression of short stature homobox 2 ( SHOX2) in human esophageal squamous cancer cells . Methods The bioinformatics software TargetScan , miRanda, PicTar, miRTarget2, and PITA were used to predict the assumptive targets of miR-375 in SHOX2.Then, two recombinant luciferase gene report plasmids containing wild pSHOX2 3′UTR ( pSHOX2-375-WT ) and mutant pSHOX2 3′UTR ( pSHOX2-375-mut ) were constructed , sequenced , and identified.Human esophageal squamous cancer cells were co-transfected with miR-375 mimics and pSHOX2-375-WT or pSHOX2-375-mut, respectively , and divided into 7 groups: pmiR, pSHOX2-375-WT, pSHOX2-375-WT +miR-375, pSHOX2-375-WT +miR-NC, pSHOX2-375-mut, pSHOX2-375-mut+miR-375, and pSHOX2-375-mut+miR-NC, each subjected to the measurement of luciferase activity .The expressions of SHOX 2 mRNA and protein were de-termined after transfection of the esophageal squamous cancer cells with miR-375 mimics, and so were the expressions of miR-375 and SHOX2 in the esophageal squamous carcinoma tissue samples obtained postoperatively . Results Prediction with the five software showed only one conserved function site of miR-375 in SHOX2 3′UTR at 1156-1170 bp.Luciferase activity was significantly lower in the pSHOX2-375-WT+miR-375 group (0.261 ±0.036) than in the pmiR (1.818 ±0.061), pSHOX2-375-WT (1.820 ±0.086), pSHOX2-375-WT+miR-NC (1.851 ±0.094), pSHOX2-375-mut (1.861 ±0.059), pSHOX2-375-mut +miR-375 (1.896 ± 0.048), and pSHOX2-375-mut+miR-NC group (1.760 ±0.062) ( P<0.01).SHOX2 mRNA and protein expressions were sup-pressed by the overexpression of miR-375 in the EC9706 cells.The expression of miR-375 was decreased, while that of SHOX2 in-creased in the esophageal squamous carcinoma tissue as compared with the normal esophageal tissue . Conclusion MiR-375 regu-lates the expression of the SHOX 2 gen in esophageal squamous cancer cells .
