Objective To evaluation the value of fusion images of dynamic contrast enhanced MRI (DCE MRI) with transrectal ultrasound(TRUS) and conventional TRUS in prostate biopsy for prostate cancer.Methods The clinical data of 127 patients suspected as early-stage prostate cancer were retrospectively analyzed.79 patients underwent prostate biopsy guided by conventional TRUS(group A).48 patients underwent prostate biopsy guided by fusion images of DCE MRI with TRUS(group B).Then the diagnostic rates,puncture times and complications in the two groups were compared.Results The cases with confirmed prostate cancer were 31 in group A and 22 in group B.The first time diagnostic rates of biopsy were 20.2％(16/79) in group A,and 39.3％ (19/48) in group B respectively(P ＜0.05).The first time sensivity,specifity,positive predictive value and negative predictive value of biopsy were 51.6 ％,100 ％,100％,77.4％ in group A and 86.3％,100％,100％,89.6％ in group B.Puncture times was 15.40 ± 4.67 and 13.01 ± 3.87 respectively.The Gleason score was 6.21 ± 0.91 and 6.35 ± 0.81 respectively.The complication rates were 19.0％(15/79) in group A and 12.5％(6/48)in group B.Conclusions For patients with earlystage prostate cancer,the combination of DCE-MRI and TRUS to guide transrectal prostate biopsy was recommended.It showed an increase in the first time diagnostic rate of biopsy while a reduction in the times and complications of prostated biopsy.

Objective To compare the curative effect of tension-free hernioplasty and transabdominal preperitoneal herniorrhaphy(TAPP)in adult patients with inguinal hernia.Methods A prospective randomized controlled study.A total of 240 patients with inguinal hernia were randomly divided into TAPP group and tension-free hernioplasty group(open group),120 patients in each.Results In both the groups,the surgical treatments were completed.The mean operation time in TAPP group was significantly longer than that in open group [(77?15)min vs(48?9)min,t=18.147,P=0.000],and the average cost for surgery in TAPP group was significant higher than that in open group [(7363?351)yuan vs(4635?242)yuan,t=72.663,P=0.000].However,the patients in TAPP group returned to activity and was discharged earlier than those in the open group [(6?1)h vs(10?2)h,t=-19.385,P=0.000;and(3?1)d vs(5?1)d,t=-15.300,P=0.000;respectively].No significant difference was detected in the severity of postoperative pain,complications,and recurrence rate between the two groups.Conclusion Both TAPP and tension-free hernioplasty are worth being wildly used.

Objective:To study the effect of p75NTR gene on the apoptosis of tongue squamous cell carcinoma Tca8113 cells. Methods:p75NTR +Tca8113 cells were isolated from Tca 8113 cell line and transfected by p75NTR siRNA using lipofectamine. p75NTR mRNA and protein expression was examined by real time RT-PCR and western blot respectively.Cell proliferation was stud-ied by MTT assay,cell apoptosis was examined by flow cytometry.Results:Proliferation of p75NTR + cells was faster than that of p75NTR - cells.Transfection of p75NTR siRNA inhibited p75NTR mRNA and protein expression in p75NTR + Tca8113 cells,inhibi-ted the proliferation and increased the apoptosis of the cells.Conclusion:p75NTR gene plays a role in the apoptosis of Tca8113 cells.

Objective To study the rehabilitation effects of the cochlear implants on prelingually deaf children with alba abnormality.Methods A retrospective analysis of the effects of CIs was conducted in the prelingually deaf children of 11 cases of the children with abnormal alba(the research group) and 18 cases of the children who had normal alba(the control group) at the First Affiliated Hospital of Fujian medical university.All the operations were completed by the same doctor.There were no obvious complications during and after the operation.The cochlear implants were turned on after one month and the prelingually deaf children with extremely severe bilateral sensorineural deafness were trained for speech at the rehabilitation centre.The assessment criteria of the categories of auditory performance(CAP) and speech intelligibility rate(SIR) were used.After six months and twelve months of the operation, the family members were followed who have direct contacts with the children.The evaluation of data between the research and the control groups was administered.Results In the research group, the average level of CAP after six months'' post-operation was 2.41±0.47.But in the control group, the average level was 3.28±0.45.In the research group, the average level of SIR after six months'' post-operation was 1.27±0.44.There were 3 children in the research group at level 2, but in the control group, the average level was 1.89±0.31.Two children in the control group were level 1 while the others were level 2.In the research group, the average level of CAP after twelve months'' post-operation was 4.00±0.43 while only one child at level 3.There was one child at level 5 in the research group, the rest were level 4.There was a statistically significant difference in the average level of the CAP after six months'' post-operation(t=4.983, P<0.05) and in the average level of the SIR after six months'' post-operation(t=4.371, P<0.05).There was no statistical difference in the average level of the CAP after twelve months'' post-operation(t=1.033, P>0.05) and in the average level of the SIR after twelve months'' post-operation(t=0.434, P>0.05).Conclusion There is no significant difference of the rehabilitation effects of post-operation between the prelingually deaf children with alba abnormality and those with normal alba.

Objective To compare the differences in responsive ability and oxidative stress damage between type 2 diabetic rats and normal rats under acute sepsis associated with stress hyperglycemia.Methods GK rats with type 2 diabetes and Wistar rats were established critical ill models of sepsis by intraperitoneal injection of 5 mg/kg lipopolysaccharide(LPS).Before and after LPS injection,serum levels of proinflammatory cytokines tumor necrosis factor α (TNF-α),interleukin (IL)-1β3,and IL-6,and anti-inflammatory cytokine IL-10 were determined.Malondialdehyde (MDA) and total antioxidative capacity (T-AOC) levels in serum and tissues (lung,liver,kidney,heart) were measured by colorimetric determination.Results Before LPS injection,serum levels of TNF-α,IL-6,and IL-10 in GK rats were higher than those of Wistar rats.The serum levels of TNF-α,IL-6,and IL-10 after LPS injection were raised in both GK rats and Wistar rats (all P＜0.05).At baseline,serum MDA level of GK rats was higher than that of Wistar group [(25.76 vs 12.71) μmol/L,P＜0.05],while T-AOC level were lower [(0.60 vs 2.8) U/ml,P＜0.05].One hour after LPS injection,the serum MDA level in two kinds of rats significantly increased compared with those of their baseline levels [(32.30 and 20.19) μmol/L,both P＜0.05],while their serum T-AOC level decreased [(0.20 and 2.08) U/ml,P＜0.05]).There were no signigicant differences in the change trend of serum MDA and T-AOC between the two kinds of rats.MDA and T-AOC levels in tissues had no significant difference before and after LPS injection in GK and Wistar rats (P＞0.05).Conclusions The rats with type 2 diabetes had lowered level of proinflammatory factors and raised level of anti-inflammatory factors under acute sepsis,presenting better tolerance and lowered probability of inflammatory diffusion compared with normal rats.

Acute rejection is one of the serious early postoperative complications after liver transplantation.Many studies have shown that acute rejection was mainly mediated by T cells,while humoral factors were responsible for chronic rejection.However,accumulating evidences have demonstrated that humoral immune factors also played an important role in early acute rejection and usually resulted in severe adverse events.Here we clarify the role of humoral immunity in liver transplant rejection,which may help guide the clinical management of such patients with humoral rejection after liver transplantation.

Objective To investigate the correlation between pancreatic nuclear factor-κB (NF-κB) activation, cell apoptosis and pancreatic injury. To determine effects of N-acetylcysteine (NAC) on pancreatic injury in rats with acute necrotizing pancreatitis (ANP). Methods Thirty-three Wistar rats were divided into five groups: normal group, normal saline (NS) group, ANP group, prophylactic and therapeutic groups with NAC randomly. ANP was produced by 3.5% sodium taurocholate retrograde injection. In the prophylactic group, rats received intravenous (i. v.) injection of NAC (300 mg/kg) 1 hour before taurocholate injection and in the therapeutic group, NAC i.v. injection was given 1 hour after sodium taurocholate injection. Animals were sacrificed at 12 hours after induction of pancreatitis. Activation of NF-KB in pancreatic tissues was determined by electrophoretic mobility shift assay(EMSA). Cell apoptosis was assessed by modified TUNEL method. The following parameters were also measured: plasma levels of amylase and lipase, pancreatic wet/dry weight ratio and histologic grading. Results Taurocholate pancreatitis is characteristic of necrosis, haemorrhage, and severe leukocyte infiltration in the pancreas. Plasma amylase and lipase levels, pancreatic wet/dry weight ratio increased in rats of ANP. NF-κB banding activity was higher after pancreatitis induction (6.03±0.41). When NAC was given 1 hour before induction of pancreatitis, the activation (3.28±0.42) of NF-κB was prevented with significantly decreased severity of pancreatitis as assessed by amylase, pancreatic wet/dry weight ratio. The number of apoptotic cells in pancreatic tissue sections was greater in rats treated with NAC than in rats not treated with NAC. There was a negative correlation between NF-κB banding activity and apoptosis of pancreatic cells (r=-0.96, P< 0.01) and there was a positive correlation between NF-κB activation and histopathological score (r=0.63, P<0.01). Histopathological score of pancreatic injury had negative correlation with apoptosis of pancreatic cells(r=-0.98, P<0.01). Conclusion Early blocked NF-κB activation with NAC increases cell apoptosis in pancreatic tissue and decreases edema of pancreas and severity of pancreatitis in rats with ANP.

Objective To explore the feasibility of Ilizarov technique in managing large tibia defects combined with soft tissue defects.Methods A total of 24 patients with large tibial defects combined with soft tissue defects caused by compound open tibial fractures were fixed with Ilizarov technique from September 2003 to September 2010.All patients belonged to open tibial fractures,including 20 patients with Gustilo type Ⅲ B and four with Gustilo type Ⅲ C.After debridement,the soft tissue defect areas was 10 cm ×6 cm and the bone defect was(8 ±4)cm.Fifteen patients with tibial defects ＜5 cm were treated with one stage debridement,fibula resection and tibial defect end compression.The other nine patients with tibial defect ＞ 5 cm were managed by one stage debridement,bone transport and bone lengthening.Then,15 patients were treated with one stage debridement,wound closure or wound reduction,bone grafting treatment and second stage cleansing of the incarcerated skin and fracture end.Results All patients were followed up for average 14 months(10-24 months),which showed reconstruction of the bone defects,restoration of the limb length,fracture healing and less than 2 cm difference between health limb and contralateral limb.One patient experienced common peroneal nerve palsy after operation,but recovered three months later.Of all,19 patients recovered without extra surgery,three restored with skin graft and two received skin flap.Conclusion Ilizarov technique is an effective option for treating the tibial defects combined with soft tissue defects at one stage.

Objective:To evaluate the molecular diagnosis marker of papillary thyroid carcinoma (PTC),the relationship between lymphatic metastasis of central neck compartment PTC,and the opera-tion indication of prophylactic central neck dissection.Methods:We conducted a retrospective study, including 275 PTC patients and detected their BRAF mutation rates during 201 2 and 201 4 and explored the risk factors of the central node lymphatic metastasis by Logistic regression model.Results:Of the 275 PTC patients,224 (81 .5%)were female and 51 (1 8.5%)were male.BRAF mutational rates were 53.8% (1 48 /275)and lymphatic metastasis 57.8% (1 59 /275).Multivariate analysis showed calcifica-tion (ORadjusted =1 .47,95%CI:1 .1 0 -1 .98,P =0.01 ),tumor diameter (ORadjusted =1 .48,95%CI:1 .04 -2.30,P =0.048)and age (ORadjusted =1 .48,95%CI:1 .04 -2.30,P =0.048)were associa-ted with lymphatic metastasis.In stratified analysis,BRAF mutation (ORadjusted =3.1 9,95%CI:1 .1 8 -9.43,P =0.023 )in clear boarder group and BRAF mutation (ORadjusted =4.84,95% CI:1 .68 -1 3.84,P =0.003)in calcification group were more likely to have lymphatic metastases.Conclusion:Central neck metastasis takes up a high ratio in papillary thyroid cancer patients,BRAF mutation in pa-pillary thyroid carcinoma is a characteristic molecular event.Furthermore,patients with calcification un-der ultrasound detection,lower age group and longer tumor diameter are more susceptible to suffer central neck metastasis.Especially for stratified analysis,non-calcified BRAF mutation or BRAF mutation with clear border under ultrasound detection are more susceptible to suffer central neck metastasis,and radical prophylactic central neck dissection should be carried on for these patients.
