AIM:This study was to investigate the expression and significance of Bmi-1 in colorectal carcinoma (CRC),and to explore the effect of Bmi-1 on Ki67 expression in human CRC.METHODS:The samples from sixty CRC,thirty adenomas and twenty normal colorectal mucosal tissues were used in this study. The expression of Bmi-1 protein was detected by immunohistochemistry. The clinicopathological features and survival rate of patients were also analyzed.RESULTS:The overexpression of Bmi-1 was respectively 25.0%,6.7%and 0% in CRC and adenomas as well as normal colorectal mucosal tissues. The results showed that the expression of Bim-1 was significantly higher in CRC,compared with that in adenomas and normal colorectal mucosal tissues (P0.05). Kaplan-Meier survival analysis showed that the overexpression of Bmi-1 reduced significantly survival of CRC patients (P

Objective To investigate the separate and combined detection value of serum carbohydrate antigen 125 (CA125),human epididymis protein 4 (HE-4) and D dimer (D-dimer) in the diagnosis of ovarian cancer.Methods One hundred and twenty ovarian cancer patients were selected as the observation group,one hundred and twenty patients with ovarian benign tumor as the benign group,eighty women with healthy physical examination results as the control group,then the chemiluminescence immunoassay was used to detect the expression of serum CA125 and HE-4 of the three groups,and the immune turbidimetric method was applied to examine the expression of D-dimer.At last,the diagnosis efficiency of CA125,HE-4 and D-dimer in separate and combined detection was calculated.Results CA125 in the observation group was (623.07±274.18) U/ml,HE-4 was (594.22±329.068) ng/ml and D-dimer was (418.57±276.75) ng/L,CA125 in the benign group was (45.09±32.58) U/ml,HE-4 was (97.92±57.52) ng/ml and D-dimer was (204.52±80.07) ng/L;CA125 in the control group was (40.23±28.16) U/ ml,HE-4 was (85.65±37.27) ng/ml and D-dimer was (187.57±65.74) ng/L,the differences between the three groups were statistically significant (F=122.82,89.91,54.46;P<0.05).The level of CA125 in the serum of patients with advanced stage (stage III-IV) was (586.10±278.33) U/ml,HE-4 was (437.49±238.06) ng/ml,D-dimer was (493.78±274.45) ng/L,in the early stage (stage I-II),the level of CA125 in the serum of patients with ovarian cancer was (372.12±265.31) U/ml,HE-4 was (673.64±301.68) ng/ml,D-dimer was (364.84±267.54) ng/L,and the difference was statistically significant (t=4.244,4.78,2.560,P<0.05).The detection sensitivity and specificity of CA-125 were 71.67% and 62.50% respectively.The sensitivity of HE-4 was 74.17% and the specificity was 75.00%.The sensitivity of D-dimer was 62.5% and the specificity was 60.00%.The combined detection sensitivity of the three was 80.00% and the specificity was 77.5%.Conclusion The sensitivity and specificity of the three tumor markers in combined detection were higher than those of separate detections,so the combined detection of CA125,HE-4 and D-dimer can further improve the diagnosis level of ovarian cancer.

Objective Acute poisoning is frequently encountered at emergency department. This study was to investigate the epidemiology and characteristics of patients with acute poisoning who were treated at the Emergency Center, Fujian Provincial Hospital, China. Method We retrospectively analyzed the gender, age, causes of poisoning, types of poisons, poisoning route, emergency diagnoses, outcomes, and prognoses of these patients.Results Altogether 2867 patients with acute poisoning were treated from January 2004 to December 2009. The ratween 18 and 40 years old. The incidence of acute poisoning was as high as 11.33% in January each year. The incidence of poisoning was in a descending order: alcohol poisoning (54.55%), medication poisoning (25.95%), pesticide poisoning (5.65%), and drug poisoning (4.88%). Most (56.44%) of the patients with drug poisoning were under 25 years and their mean age was significantly lower than that of patients with medication poisoning or alcohol poisoning ( P ＜ 0.01 ). Approximately 69.54% of the patients were followed up after emergency treatment, 30.39% were hospitalized, and four patients died. Conclusions Acute poisoning is largely alcohol poisoning and medication poisoning in a city. The emergency green channel "pre-hospital emergency care-emergency department-hospital treatment" can significantly improve the survival rate of patients with acute poisoning.

Objective To compare the anthelmintic effect of albendazole with that of triclabendazole against Fasciola giganti-ca. Methods Two patients infected with Fasciola gigantica were investigated,and one was administered with albendazole orally (200 mg,twice per day for 5 days)and another was administered with triclabendazole[10 mg/(kg?d)for 2 days]. Their total fe-ces were collected daily during the period of whole therapy,and the eggs of the parasite were collected by using the nylon bag method,and incubated at 28℃. Results The parasite eggs were detected from the first patient’s dejecta on the 1st,2nd and 5th day after the end of the treatment,and no miracidiums hatched out as well as no eggs developed during the period of 25 days of the incubation. Meanwhile,her body temperature fluctuated between 37.4℃and 38.3℃,and she still complained bellyache. For the other invalid,the eggs were not detected on the 2nd and 5th day after the end of the treatment. However,the eggs before and dur-ing the treatment developed the miracidiums of Fasciola gigantica on the 13th day after the incubation,but the eggs collected from the 1st day after the termination of the therapy did not develop and no miracidiums hatched out. At the same time,the signs and symptoms of the patient vanished after the 4th day of the end of the therapy. Conclusions Albendazole has no obvious insecticid-al activity on adult Fasciola gigantica in the short term,but may affect the development of eggs. Triclabendazole has the anthelmin-tic effect on the adults as well as eggs of Fasciola gigantica. In addition,triclabendazole has the characteristics of well curative ef-fect,short course of treatment,and no obvious side effects.

OBJECTIVETo discuss the clinical effects and superiority of applying external fixation and bone transport to treat osteomyelitis and bone defect of femoral bone.

METHODSFrom August 2008 to December 2013,16 patients with osteomyelitis and bone defect of femoral bone were treated including 11 males and 5 females with an average age of 42 years old ranging from 13 to 62 years old. The average course of disease was 18 months ranging from 2 months to 4.5 years, and the average length of bone defect was 7.8 cm ranging from 4.5 to 15 cm. The bone defect of all cases were treated by external fixation and bone transport, the bone transport began at 1 week after operation, 1 mm per day and 4 times per day.

RESULTSAll patients were followed up for 10 to 36 months (means 22.5 months). One patient did not cooperate with treatment leads to the failure, then took the amputation. The remaining 15 cases of osteomyelitis were under control, including 12 cases of bone transport achieved one stage bone union, 3 cases achieved bone union via bone graft from iliac bone. The bone union time was 5 to 13 months(means 7.9 months). Thirteen patients almost obtained the same length of two lower extremities,2 patients had shortening of 1.5 to 2 cm. The time of moving the external fixation was from 6 to 16 months (means 9.3 months).

CONCLUSIONApplication of external fixation and bone transport is an effective method in treating the osteomyelitis and bone defect that can control the infection, eradicate wounds, and be the equalization of limb length.

Objective To evaluate the effects of misregistration with different directions and magnitudes between SPECT and CT on image quality and semi-quantification of MPI.Methods The data of 19 healthy volunteers (11 males,8 females ; mean age:(65.3 ± 9.6) years) were retrospectively analyzed.They all had a low pretest likelihood of coronary artery disease according to exercise and rest 99Tcm-MIBI MPI.The CT attenuation correction (CTAC) was performed on a SPECT/CT system.The CT images were manually shifted by 0.5,1.0,1.5,2.0,2.5,3.0,3.5,4.0,4.5 cm distance along the up/down,left/ right,and anterior/posterior axes respectively by using the system built-in software.The counts of the left ventricle were measured using myocardial Bull's eye generated from the reconstructed CTAC images.The image quality and semi-quantification of the CTAC images reconstructed from the raw data with and without shifting were compared and analyzed.Paired t test was used to analyze the data.Results There was no visible artifact with 0.5 cm shifting.The image quality was deteriorated significantly and the counting difference was significant with shifting distance greater than or equal to 1.0 cm.The image artifact of apex wall was mainly due to the upward shift,anterior and apex wall due to the downward shift,septal wall due to the leftward shift,anterior,apex and lateral wall due to the rightward shift,lateral and infero-posterior wall due to the forward shift,anterior,apex and septal wall due to backward shift.The counting difference caused by the downward shift was significantly more severe than that caused by the upward shift ((-9.68±8.06) ％ and (-2.04±1.83)％,t=6.573,P＜0.01) ; and the rightward shift was more severe than the leftward shift ((-9.02± 8.47) ％ and (-4.38±3.67) ％ ; t =1.987,P＜0.05).The image artifacts in anterior,apex and lateral walls were more severe than those in the infero-posterior and septal walls.Conclusions CTAC image artifacts in myocardial perfusion SPECT/CT studies could be caused by misregistration ≥ 1.0 cm.Different directions and magnitudes of shift could result in different degrees of attenuation artifacts at different locations on the original images.

Objective To determine the effect of histotype and histodifferentiation on the maximum standardized uptake value (SUV_(max)) of non-small cell lung cancer (NSCLC) ~(18)F-fluorodeoxyglucose (FDG) PET/CT imaging.Methods Two hundred and sixty patients with NSCLc underwent ~(18)F-FDG PET/CT imaging.They were classified according to (1) histotype:as adenocarcinoma (AC),squamous cell carcinoma(SQC),adenosquamous carcinoma (ASC) and other type carcinoma (OTC),and (2) histodifferentiation:as grade Ⅰ (well-differentiated),grade Ⅱ (moderate-differentiated) and grade Ⅲ (poor-differentiated).The SUV_(max) and size(long diameter)of the primary lesions were measured.Multivariate regression analysis was used to analyze the relationship between the SUV_(max) and variable factors including histotype,histodifferentiation,lesion size,age,sex,body height,body weight,body mass index (BMI),blood glucose level,dose,and rate of dose.Results Two hundred and sixty patients had 260 primary NSCLC tumors.There were 161 AC(15 grade Ⅰ,88 grade Ⅱ,58 grade Ⅲ),74 SQC(6 grade Ⅰ,39 grade Ⅱ,29 grade Ⅲ),15 ASC(7 grade Ⅱ,8 gradeⅢ)and OTC(8 large cell,2 carcinosarcoma).Only lesion size (F=87.046.P＜0.001),histodifferentiation (F=87.604,P＜0.001) and histotype (F=66.663,P＜0.001) were included for multivariate regression analysis with SUV_(max).After adjustment for lesion size,the SUV_(max)(mean and 95%confidence interval) in ascending order was AC Ⅰ:3.3(2.1-4.5),ACⅡ:6.0(5.5-6.6),SQCⅠ:6.1(4.2-8,0),ASC Ⅱ:6.6(4.8-8.4),SQCⅡ.7.8(7.0-8.6),OTC:8.1(6.6-9.6),AC Ⅲ:8.3(7.6-8.9),ASC Ⅲ:8.7(7.0-10.4),and SQC Ⅲ:8.9(8.0-9.8).11he SUV_(max) of AC Ⅰ was significantly lower than that of SQC Ⅰ(q=-2.786,P=0.017),same for AC Ⅱ and SQC Ⅱ(q=-1.776,P＜0.001),but no statistically significant differences were found among AC Ⅲ,ASC Ⅲ and SQC Ⅲ(q=-0.593,-0.422,0.171,P=0.288,0.642,0.860,respectively).For the same histotype lesions,the difference of SUV_(max) among AC Ⅰ,Ⅱ and Ⅲ was statistically significant(q=-2.720,-4.943,-2.223,all P＜0.001),as also for SQC Ⅰ and Ⅲ(q=-2.751,P=0.012).Conclusion Histotype and histodifferentiation are significant correlative factors for ~(18)F-FDG uptake of NSCLC,with histodifferentiation being the factor with greater impact.
