OBJECTIVETo compare the efficacy between eccentric fixation and internal fixation for treatment of intertrochanteric fractures of femur,to provide a theoretical basis for the selection of the treatment method of the intertrochanteric fractures of femur.

METHODSFrom February 2007 to January 2010,82 patients with femoral intertrochanteric fracture were treated by internal fixation including 39 cases of eccentric fixation involving 23 males and 6 females, aged from 41 to 81 years old with an average of (62.68±10.69), using the DHS or proximal femoral locking plate; 43 cases of intramedullary fixation involving 15 males, 28 females,aged from 43 to 78 years old with an average of (62.60±8.37),using PFN or PFNA fixed. The surgical incision length, operative time, blood loss and postoperative Harris score between two groups were compared.

RESULTSThe wound of two groups were primary healing without operative complications. All cases received follow-up for an average time of 18.3 months (12 to 28 months). The incision length, operative time and blood loss had a statistically significant difference between two groups (P<0.05). Harris scores of hip joint function at 1 month after operation had statistically significant difference between two groups (P<0.05), and Harris scores at 12 months after operation had no statistical significance difference between two groups. The rate of excellent and good was 89.7% in eccentric fixation group and 90.7% in intramedullary fixation group,the difference was not statistically significant (t=0.0613, P>0.05). In eccentric fixation group, there was 1 case of fracture nonunion with DHS loose and ensuing hip varus deformity. In intramedullary nail fixation group, there was no anti-rotation out,distal intramedullary nail of femoral refracture occurred in 1 case.

CONCLUSIONTwo treatment methods for the treatment of femoral fractures had a good therapeutic effect,but the intramedullary fixation had shorter operative time and less blood loss than the eccentric fixation,it prior to apply to osteoporosis and unstable femoral intertrochanteric fractures.

Objective To compare the effects and complications of lumboperitoneal shunt ( LP ) and ventriculoperitoneal shunt ( VP ) in the treatment of post?traumatic hydrocephalus. Methods Eighty patients with post?traumatic hydrocephalus treated in the neurosurgery department of Zhangjiagang Hospital of Traditional Chinese Medicine from March 2014 to March 2010 were retrospectively analyzed. The patients were randomly divided into two groups,40 patients treated with LP were assigned into the LP group and 40 patients undergone VP treatment were seen as the VP group. All patients were followed up for 1 year to investigate and compare the symptom improvement rate,neurological deficit score and the incidence of complication of the two groups. Results The total effective rate of hydrocephalus disappearance in the LP group was 41. 50% ( 37/40) and 87. 50%( 35/40) in the VP group. The difference between the two groups was not statistically significant (χ2=0. 556,P=0. 456);the neurological deficit scores before treatment in the LP group and VP group were (28. 35±8. 64) points and (29. 13±7. 98) points,there was no significant difference between the two groups (t=0. 419,P=0. 676) . The difference in the scores of neurological deficit after treatment in the LP and VP group was not statistically significant ( (19. 32±5. 34) points vs. (21. 62±4. 86) points,t=1. 480,P=0. 143),the average scores of neurological deficits in the two groups were significantly better than those before treatment ( t=5. 623, 5. 084,P<0. 001 ) . There was no significant difference in the average score of improvement of urinary incontinence between the two groups before and after treatment ( t=0. 376,1. 265,P>0. 05) ,the average score of urinary incontinence improvement after treatment in both groups were better than those before treatment ( t=4. 891,5. 370,P<0. 001) . In the LP group,the incidence of bleeding,infection,shunt related complications and shunt abnormality were all 2. 50% ( 1/40 ) , the overall complication rate was 10. 00%, the incidence of bleeding,infection,shunt related complications and shunt abnormality in the VP group were 7. 50% (3/40), 10% ( 4/40 ) , 5% ( 2/40 ) 10%, ( 4/40 ) , the overall complication rate was 32. 50%, there was significant difference between the two groups (χ2=6. 050,P=0. 014) . Conclusion LP and VP have significant curative effect on the treatment of post?traumatic hydrocephalus,but the overall incidence of LP complication after 1 year is significantly lower than that of VP,and is worth popularizing widely in clinical practice

Objective To investigate the effect of early application of clean intermittent catheterization(CIC) in infants with neurogenic bladder(NB).Methods Eighty-seven children with NB diagnosed in our urodynamic center were less than 1 year old when they first came to hospital from January 2007 to January 2010, and CIC was carried out at different age.Sixty-four patients were followed up for a long time and divided into early CIC group(less than 1 year old children) and late CIC group(more than 3 years old children) according to the treatment time.Early CIC group included 29 patients [19 boys and 10 girls with the mean age of (7.5 ±2.8) months].And 4 cases were suffering from postoperative spina bifida manifesta;22 cases with spina bifida occulta;2 cases with sacral dysplasia;1 case with meningitis.Late CIC group included 35 patients [20 boys and 15 girls with the mean age of (8.0 ±2.9) months].2 cases were suffering from postoperative spina bifida manifesta;28 cases with spina bifida occulta;4 cases with sacral dysplasia;1 case with postoperative pelvic surgery.Before the treatment, there were no significant differences of the bladder compliance (BC), the maximum cystometric capacity (MCC) and the safety bladder capacity (SBC) between two groups.Urodynamic parameters and complications of 64 patients who were successfully followed up for 6 years were compared.Results After 3 years follow up, BC, SBC and MCC in early CIC group [(8.5 ± 1.9) ml/cmH2O, (140 ±25) ml, (142 ±29) ml]were significantly higher than those of late CIC group [(7.0 ± 2.2) ml/cmH2O, (110 ± 31) ml, (120 ± 28) ml;all P ＜ 0.05].After 6 years follow up, BC, SBC and MCC in early CIC group [(12.0 ±2.5) ml/cmH2O, (210 ±26) ml, (230 ±30) ml] were significantly higher than those of late CIC group [(9.3 ± 2.3) ml/cmH2O, (192 ± 31) ml, (205 ± 35) ml;all P ＜ 0.05], and the vesicoureteral reflux rate [24.1％ (7/29)] in early treatment group was significantly less than that in late treatment group [54.3％ (19/35), P ＜ 0.05].Increases in BUN and serum creatinine were found in 6 cases (20.7％) in early CIC group and 17 cases (48.6％) in late CIC group, the difference was significant (P ＜ 0.05).Conclusion For NB patients, the effect of early CIC is better than that of late CIC.

The endophytic bacteria of the mangroves were studied in this paper. The results show that there are 1.728 (0. 195 -4.225)?104cfu/g (fw) bacterial endophytes in the variety of mangroves, the most population of the endophytic bacteria was found in Rhizophora stylosa, the figure was4. 225?104cfu/g (fw) , the next was Bruguiera gymnorrhiza, Aegiceras corniculatum, Kandelia candel and Avicennia marina. In parts of the mangroves, the contents of the bacteria in stem was the most, the figure was 1. 649?10 cfu/g (fw) , then the root and the leaf. Of the bacteria, about 43. 53% strains expressed the antagonism against the growth of the plant pathogens, such as Fusarium oxyspontm f. sp. cubense , Colletotrichum sp. and Rahtonia solanaceance etc. and these bacteria were identified as Bacillus sp. . The results also showed that 9 of the 13 strains (69. 23% ) could promote the growth of the tomato, while 4 strains (30. 77% ) restrained the tomato's growth.

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.

Objective To compare the efficacy of 18F-FDG PET/CT, 99Tcm-MDP bone scintigraphy (BS), and combination of the two techniques (PET/CT + BS) for detecting bone metastasis by ROC curve analysis. Methods All 296 patients with various cancers, who underwent both 99Tcm-MDP BS and 18F-FDG PET/CT within two months, were retrospectively analyzed. These images were interpreted according to 5-point scale (0: definitely negative, 1: probably negative, 2: equivocal, 3: probably positive, 4:definitely positive for bone metastasis), and the scale of PET/CT + BS was the sum of PET/CT and BS. In light of the confirmed diagnosis derived from pathology or follow-up, ROC curve analysis was performed.The area under the ROC curve (AUC) was compared by z-test. Results Of 296 cases, 61 (20.6%) were confirmed as bone metastases and 235 (79.4%) were negative. The AUC were 0. 919 (95% confidence interval (95% CI) :0. 867 - 0. 971) for BS, 0. 949 (95% CI: 0. 906 - 0. 991) for PET/CT, and 0. 994 (95% CI: 0.988-0.999) for PET/CT + BS, rctrospectively. The AUC of PET/CT + BS was statistically significantly larger than that of BS (z=2. 866, P=0.004) or PET/CT (z =2.027, P=0.043), while the AUC of PET/CT was larger than that of BS, but no statistically significance (z = 0. 881, P = 0. 378) was showed. The optimal sensitivity, specificity, accuracy, positive predictive value (PPV), negative predictive value(NPV) were 90. 2% (55/61), 85. 1% (200/235), 86. 1% (255/296), 61. 1% (55/90), 97. 1%(200/206) for BS, 88.5% (54/61), 97.0% (228/235), 95.3% (282/296), 88.5% (54/61), 97.0% for PET/CT, and 98.4% (60/61), 95.7% (225/235), 96.3% (285/296), 85.7% (60/70) for PET/CT + BS,respectively. The specificity (χ2 = 19.862, P<0. 001), accuracy (χ2 = 23. 361, P<0.001) and PPV (χ2 =11. 791, P =0.001) of PET/CT + BS were significantly higher than those of BS, the sensitivity of PET/CT +BS was significantly higher than that of PET/CT (χ2 =4.167, P=0.031). Compared with BS, PET/CT had a higher specificity (χ2 = 19.600, P<0. 001), accuracy (χ2 = 13. 755, P <0. 001), PPV (χ2 = 13. 608, P <0. 001), but their sensitivity showed no statistically significant difference (χ2 = 0, P = 1. 000). Conclusions The efficacy of 18F-FDG PET/CT for detecting malignant bone metastasis was superior to that of 99Tcm-MDP BS alone. The detection ability can be obviously improved by combination of the two techniques.
