Objective: Our aims were to measure DNA content in primary lung cancer and to study the relationship between the DNA content and TNM stage, histological differentiation of tumor cell, cellular proliferation, and apoptosis. Methods: The DNA content and cellular proliferation were analyzed using flow cytometry. Tumor cell apoptosis was detected by using TUNEL method. Results: (1) The DNA index (DI) distribution ranged from 0.829 to 2.514. There were 41 cases (77.4%) of DNA aneuploid. The distribution of DI and DNA aneuploid was independent of histological subtypes(P>0.05).(2) With the increase of TNM stage, the DI and the rate of DNA aneuploid increased(P<0.05).(3) There was relationship between DI and histological differentiation of tumor cell. The DI was higher in tumors of poor differentiation than those in tumors of moderate and good differentiation(P<0.05 and P<0.01). (4) The cellular proliferation index of aneuploid tumors was significantly higher than that of diploid tumors(P<0.01), while apoptosis index of aneuploid tumors was significantly lower than that of diploid tumors (P<0.01). Conclusion: Correlations exist between DNA content and TNM stage, hiological differentiation, cellular proliferation, and apoptosis.

Background Some drugs with inhibitory effect on the proliferation of lens epithelial cells have a limiting application in clinic because of their adverse response.To screen the effective and less side-effect drug for supressing LECs growth is very inportant for the prevention and treatment of after cataract.Objective This study was to explore the effects of docetaxel on LECs growth and compare its role with epirubicin hydrochloride,pirarubicin hydrochloTide and rahitrexed.Methotis Immortalized human LECs line (SRA01/04) were cultured and passaged.Different concentrations of docetaxel,epirubicin hydrochloride,pirarubicin hydrochloride and rahitrexed were added into the medium respectively for 24.48 and 72 hours.The proliferation of LECs was detect by M1Yr.Flow cytometry analysis Was used to analyze the influence of different concentrations of docetaxel on cellular cycle at 48 hours after addition of docetaxel,and Annexin V-FITC/PI marking method was used to assesse the apoptosis of LECs under the action of docetaxel.Expression of bcl-2 protein in LECs Was evaluated by Westeru blot. Result The growth rate of LECs Wag 100%in 8-519 pmol/L doeetaxel groups with the normal cell shape.Majority of abnormal cells and low growth rate were found in 66 nmoVL docetaxel group at 48 and 72 hours.The IC50 of docetaxel was lowest in 48 and 72 hours in docetaxel group in comparison to epirubicin hydrochloride and pirarubicin hydrochloride. However,no evident inhibition on LECs growth in 23.22-523.56 μmol/L of raltitrexed.At 48 hours,the percentage of LECs in G2/M phase increased as the asccnte of concentration of docetaxel,showing a significant difference among 4 groups(F=2633.05,P<0.01).The percentage of early apoptotic cells increased to 22.4%(χ2=20.00,P<0.01) and 27.9%(χ2=42.68,P<0.01)from normal control 3.1% at 48 hours after LECs exposed to 8.3 nmol/L and 266 nmol/L docetaxe.The expression of bcl-2 protein in LECs was obviously weakened after addition of docetaxel,especially 8.3 nmol/L docetaxel group. Conclusion Docetaxel,epirubicin hydrochloride and pirarubicin hydrochloride can inhibit the proliferation of human LECs in vitro.But there is no supression on LECs growth inraltitrexed.Docetaxel is proved to have a strongly arrested effect on the proliferation of LECs in comparison with epirubicin hydrochloride and pirarubicin hydrochloride and play its role at concentration-and time-dependent manner.

OBJECTIVETo compare the differences between computer aided identification and ultra-thin layer slicing in measuring the lesions of femoral head necrosis,and to confirm the accuracy and practicability of computer aided method.
METHODSFrom June 2012 to December 2013, the X-ray and MRI of 24 patients (24 hips on unilateral) were reviewed, who had avascular necrosis of the femoral head (ANFA) at late stage (stage III and IV) according to the ARCO international staging system. There were 15 males and 9 females, with an average age of (65.1 ± 8.8) years old, ranged 33 to 74 years old. Based on the software system with seeds point identification, the ragional adaptive search method with computer aid was used to calculate the volume of necrotic lesion in femoral on MRI. Then the pathological slices of those intraoperative femoral heads were made to measure the gross volume of necrotic lesion in femoral head,and the values were compared with the data in the computer.
RESULTSFor 24 hips, by the calculation of computer, the necrotic volume was (20.00 ± 3.04) cm (ranged, 18.72 to 21.29 cm³). Under the pathological section, the necrotic volume of the femoral head was (19.89 ± 3.17) cm³ (ranged, 18.55 to 21.23 cm³). In computer and pathology two kinds of measurement, the two entire femoral head volume had no significant difference using these two measurements (t = -1.227, P = 0.232).
CONCLUSIONComputer aided identification for necrotic area of femoral head adaptive can demonstrate the morphology of femoral head necrosis accurately and reliably, which will help surgeon better understand the morphology and orientation in femoral head.

OBJECTIVETo study modified ilioinguinal approach through the retrospective analysis on the surgical treatment of 63 patients with pelvic and acetabular fractures through anterior approach.
METHODSFrom January 2006 to January 2013, 63 patients with pelvic and acetabular fractures were treated with the ilioinguinal anterior approach, including 45 males and 18 females, ranging in age from 12 to 68 years old, with an average of (37.71 +/- 13.41) years old. All the patients were divided into two groups: standard ilioinguinal anterior approach group (group A) and modified ilioinguinal anterior approach group(group B). In group A, there were 26 males and 11 females, with an average age of (38.49 +/- 13.64) years old. In group B, there were 19 males and 7 females, with an average age of (36.62 +/- 13.29) years old. Intraoperative and postoperative indicators in group A and B were observed and compared, including operation incision exposure time (from skin incision to complete the ilioinguinal in front of three "windows"), the blood loss, incision close time and treatment effect of Majeed function score.
RESULTSCompared to group A, the incision exposure time of patients in group B was shorter, the blood loss (bleeding during exposure process) was less, and the close incision time was shorter, but the treatment effect of Majeed function score had no significant differences between two groups. All the patients were followed up, and the during ranged from 3 to 36 months, with an average of (18.6 +/- 9.2) months. According to Matta standard assessment reduction of pelvic and acetabular fracture, there were 28 patients got an excellent result, 8 good, and 1 fair in the group A; and 20 patients got an excellent result, 5 good, and 1 fair in the group B. According to Majeed function score for hip function, 20 patients got a satisfactory result, 12 good,4 fair and 1 poor in group A, and the mean score was 82.51 +/- 9.72; and 13 patients got an satisfactory result, 10 good, 3 fair and 0 poor in group B, and the mean score was 80.54 +/- 10.79.
CONCLUSIONThe modified approach has several advantages as follows: providing a good surgical exposure; preventing from the injury of femoral nerve, femoral artery and vein under the inguinal ligament; not needing to open the inguinal canal, which can avoid the occurrence of inguinal hernia, reduce operation prodedures and shorten operation time.

OBJECTIVETo determine the predictive value of excision repair cross complementation group 1 (ERCC1),ribonucleotide reductase subunit M1 (RRM1), and β-tubulin 3 expressions in postoperative patients with stage 1- 3 non-small cell lung cancer (NSCLC) receiving adjuvant chemotherapy.
METHODSAll NSCLC patients received surgery therapy followed by at least one cycle of adjuvant chemotherapy in our hospital from January 2004 to December 2007. The expressions of ERCC1, RRM1, and β-tubulin 3 were detected by immunohistochemical methods. The relationships among clinicopathologic characteristics, chemotherapy regimens,biomarkers' expressions and disease-free survival (DFS) were analyzed.
RESULTSThe high-expression rates of ERCC1, RRM1, and β-tubulin 3 were 36.4%,43.7%,and 38.4%,respectively. The expressions of these three biomarkers were not correlated. After a median follow-up of 35.8 months, 80 patients experienced metastatic or recurrent tumors and 40 patients died. The median overall survival was not reached and the median DFS was 24.1 months. Univariate survival analysis showed that sex, clinical stage,and adenocarcinoma or not were related to DFS, while age, smoke history, chemotherapy regimens, and expression levels of ERCC1, RRM1, and β-tubulin 3 has no prognostic significance in these surgically resected NSCLC patients who were receiving adjuvant chemotherapy. Male (P=0.036), earlier clinical stage (P=0.001), and non-adenocarcinoma (P=0.004) predicted better DFS. Stratified analysis indicated that in RRM1 high-expression strata,the regimens with gemcitabine had curtailed DFS compared with other regimens (P=0.054); in β-tubulin 3 high-expression strata,the regimens containing taxane (including paclitaxel and docetaxel subgroups) had curtailed DFS compared with other regimens (P=0.076), although there was no statistical significance. However,there were no similar predictive significance in RRM1 and β-tubulin 3 low-expression strata or in ERCC1 strata with different expression levels. COX proportional regression analysis showed that adenocarcinoma or not and clinical stage were independent risk factors of DFS in this population.
CONCLUSIONSIn postoperative NSCLC patients who are receiving adjuvant chemotherapy, patients with high expression of RRM1 tends to be resistant to gemcitabine and patients with high expression of β-tubulin 3 tends to be resistant to taxane drugs. ERCC1, RRM1, and β-tubulin 3 detected by immunohistochemistry can be biomarkers to help to choose better chemotherapy regimen and predict the effectiveness of adjuvant chemotherapy.
