AIM: To study signal transduction pathway of nitric oxide-induced PC12 cell death. METHODS: After PC12 cells were incubated with sodium nitroprusside(SNP), caspase-3 inhibitor Ⅱ plus SNP or p38 inhibitor-SB203580 plus SNP, cell survival rate was quantified by MTT assay and caspase-3 activity was measured with caspase-3 assay kits. RESULTS: SNP induced PC12 cell death in a dose- and time-dependent manner, and increased caspase-3 activity gradually. Both caspase-3 inhibitorⅡand SB203580 reduced cell death significantly, but SB203580 reduced caspase-3 activity significantly. CONCLUSION: NO might induce PC12 cell death through the activation of p38 and caspase-3.

Objective To analyze the cosmetic effects and postoperative complications of patients with early breast cancer who underwent oncoplastic breast-conserving reconstruction and traditional breast-conserving surgery.Methods From January 201 2 to October 201 5,we collected a total of 67 patients with early-stage breast cancer who underwent breast-conserving surgery in Affiliated Mindong Hospital of Fujian Medical Univer-sity.Thirty patients who underwent oncoplastic breast-conserving reconstruction were in observation group,and 37 patients who underwent traditional breast-conserving surgery were in the control group.The postoperative complications,cosmetic effects and survival situations in the two groups were compared.Results In the aes-thetic effects evaluation,22 patients (73.33%)and 1 6 patients (43.24%)had good or excellent cosmetic effects,6 patients (20.00%)and 1 4 patients (37.84%)had general cosmetic effects,2 patients (6.67%) and 7 patients (1 8.92%)had poor cosmetic effects in the observation group and control group,with a signifi-cant difference (Z =-2.51 3,P =0.01 2).Four patients (1 3.33%)in the observation group had postopera-tive complications,including that 1 patients had incisional dehiscence followed by incisional wound infection and skin necrosis,and 3 patients had subcutaneous exudates.However,2 patients (5.41 %)in the control group had postoperative complications,including 1 patients with incisional dehiscence,and 1 patients with inci-sional wound infection.There were no significant difference in the occurrence rates of postoperative complica-tions in the two groups (χ2 =0.490,P =0.484).The mean follow-up period was 28 months.We found 1 patients of local recurrence,and 2 patients of metastases in the control group.However,all patients were free of recurrence and metastases in the observation group,with no significant difference (P =0.1 40).Conclusion Oncoplastic surgical technique in the breast-conserving surgery for patients with early-stage breast cancer is a safe and effective procedure,with highly satisfactory cosmetic effects for the majority of patients,which is worth to recommend.

PurposeTraumatic pancreatitis which has a high mortality rate is likely to be misdiagnosed. This study aims to analyze the clinical manifestations and CT findings of traumatic pancreatitis, so as to improve its early diagnosis and treatment.Materials and Methods The clinical manifestations and CT images of 25 patients with traumatic pancreatitis confirmed by operation or post-treatment review were analyzed retrospectively. Pancreatic injuries were classified as superficial lesions (with the depth of trauma less than 50% of the thickness of pancreas) and deep lesions (with the depth of trauma more than 50% of the thickness of pancreas). The clinical manifestations, CT findings and the complicated organ injuries in these two types of pancreatic trauma were analyzed.Results Eight patients had superficial lesions, and 17 patients were with deep lesions. Nine patients had complicated organ injuries. Patients with deep lesions showed a more severe abdominal pain, nausea, vomiting, rebound tenderness and muscular tension than those patients with superficial lesions. The serum amylases increased in all the patients. Pancreatic-relevant complications including pancreas pseudocyst, pancreatic fluid leakage and peritonitis occurred in 7 patients who accepted a delayed operation. Three out of 8 patients with superficial pancreatic injuries were missed on plain CT scan in the first time. Among 17 patients with deep pancreatic trauma, 12 had incomplete laceration, 5 had complete laceration, and 1 was missed in the first time. The direct CT features of pancreatic trauma were focal abnormal attenuation and/or discontinuity in pancreatic parenchyma.Conclusion The clinical manifestations of patients with traumatic pancreatitis are complicated. The direct CT features of pancreatic trauma include heterogeneous density of pancreatic parenchyma and/or interruption. Trauma's depth is closely related to the main injury of pancreatic duct. It is worth to be aware of the indirect signs such as peripancreatic oozy and other viscera damages.

Objective:To investigate the expression of Plk1 ( Polo-like kinase 1 ) and Chk1/2 ( Checkpoint kinase 1/2 ) in primary hepatic carcinoma tissue and HepG2 cell. Methods: Using immunohistochemistry chemical method detected expression of Plk1,Chk1/2 protein in 40 cases of primary hepatic carcinoma tissue and 16 cases of non-tumor tissue of liver. Western blot was applied to detect the expression of Plk1 and Chk1/2 protein in HepG2 cells, and gray value was measured by using the quantitative analysis. Results:The positive rate of Plk1,Chk1/2 protein expression in primary hepatic carcinoma was 57. 5%,75. 0% and 22. 5%respectively,compared with positive rate in the liver of non-tumor tissue were 0%,25. 0% and 56. 3%. The expression of Plk1 and Chk1 protein in primary hepatic carcinoma tissue is higher than that in non-tumor tissue of liver,and the difference was statistically sig-nificant( P<0. 05 ) . The expression of Chk2 in primary hepatic carcinoma was lower than that in hepatic non-tumor tissue, and the difference was statistically significant(P<0. 05) too. The expression of Plk1,Chk1/2 protein were detected in HepG2 cells and the relative expression rate of Plk1,Chk1/2 protein were 0.39±0.0226,0.08±0.0249 and 0.01±0.0066 respectively,the difference between them was statistically significant. The expression degree was Plk1>Chk1>Chk2. Conclusion: Plk1,Chk1 protein in primary hepatic carcinoma was up-regulated,while Chk2 protein was down-regulated in these tissues. The expression degree was Plk1> Chk1>Chk2. There were relatively selective expression in primary hepatic carcinoma tissue of Plk1,Chk1 protein,then Plk1 and Chk1 might be ideal targets for therapy of primary hepatic carcinoma.

Objective Comparing the influence of neoadjuvant chemotherapy on sentinel lymph node biopsy and axillary lymph nodal staging. Methods From June 2005 to June 2007 one hundred and sixty five breast cancer patients of stage Ⅰ,Ⅱa,Ⅱb and Ⅲ underwent sentinel lymph node biopsy(SLNB) using 99mTc combining methylene blue dye as tracer to help axillary lymph node dissection(AND) were retrospectively reviewed. Sixty five patients staged Ⅱb or Ⅲ were treated with three circles neoadjuvant chemotherapy prior to SLNB and AND , another one hundred patients staged ⅠorⅡa had SLNB and AND directly without neoadjuvant chemotherapy.Results Average 14.60 axillary lymph nodes were retrieved in patients had neoadjuvant chemotherapy and 14.74 lymph nodes in patients did not have neoadjuvant chemotherapy(P>0.05),a mean number of 1.46 sentinel lymph nodes in neoadjuvant chemotherapy group and 1.5 sentinel lymph nodes in non-neoadjuvant chemotherapy(P>0.05), sentinel lymph node identification rate 96.9% in neoadjuvant chemotherapy group and 97% in non-neoadjuvant chemotherapy(P>0.05), the false negative rate was 4.6% in neoadjuvant chemotherapy group and 4% in non-neoadjuvant chemotherapy group(P>0.05). Conclusions The mean number of lymph nodes,sentinel lymph nodes,SLN identification rate and false-negative rates after neoadjuvant chemotherapy are similar to those seen in patients without neoadjuvant chemotherapy.The SLNB can accurately predict lymph node status of axillary lymph node following neoadjuvant chemotherapy.

Objective To explore the effect of exogenous recombinant human erythropoietin (rhEPO) on neuronal apoptosis in neonatal rats after hyperoxia brain injury.Methods Thirty neonatal Wistar rats were randomly divided into 3 groups by random number table method:rhEPO treatment + 800 mL/L hyperoxia group (group A),9 g/L saline +800 mL/L hyperoxia group (group B),9 g/L saline + air group (group C).Group A was given subcutaneous injection of rhEPO 1 000 IU/kg for 5 days.Group B and group C received the same dose of 9 g/L saline.Group A and group B were continuously exposed to atmospheric pressure hyperoxia model cabin to maintain the oxygen concentration in the container (800 ± 30) mL/L for 5 days.During the course of the experiment,the general situation and weight changes in rats were observed.After 5 d,all rats were sacrificed and brain tissues were taken.Neuronal apoptosis in hippocampal structural region of the newborn rats was observed by terminal deoxynucleotidyl transferase dUTP nick and labeling(TUNEL) staining.Immunohistochemical method was used to detect the expression of 5-lipoxygenase in hippocampal structural region of newborn rats.Results The weight gain and brain weight of group B were lower than those of group C,the weight gain and brain weight of group A were higher than those of group B,and the differences were statistically significant(F =11.179,8.140,all P ＜ 0.05).In group A and group B were found that the neuronal nucleus of the hippocampal neurons was partially contracted,deeply dyed,and the neuronal arrangement was loose,even with local neuron deletions and focal necrosis,but in group A neuron density was higher with less necrosis than that in group B.The neuronal cells in hippocampal structural region were neat and intact in group C.The number of TUNEL positive cells in hippocampal structural region of group B[(6.20 ± 1.93) number/high power field] was significantly higher than that in group C [(1.80 ± 0.79) number/high power field],the number of TUNEL positive cells in hippocampal structural region of group A [(4.20 ± 1.32) number/high power field] was significantly lower than that in group B,and the difference was statistically significant (F =23.912,P ＜ 0.05).The number of 5-lipoxygenase positive cells in group B [(6.90 ± 1.29) number/high power field] was significantly higher than that in group C [(1.00 ± 0.67) number/high power field],the number of 5-lipoxygenase positive cells in group A [(5.60 ± 0.97)number/high power field] was significantly lower than that in group B,and the difference was statistically significant (F =95.044,P ＜ 0.05).Conclusion rhEPO has a protective effect on neonatal rats with hyperoxia brain injury,and alleviates brain cell apoptosis caused by hyperoxia brain injury,which may interfere with the 5-lipoxygenase pathway.

Objective To compare the clinical effects of dynamic hip screw(DHS),Gamma interlocking intramedullary nail and proximal femoral nail antirotation (PFNA) in the treatment of intertrochanteric femoral fractures in elderly patients.Methods From January 2008 to June 2015,103 elderly patients with intertrochanteric femoral fracture were treated with DHS (DHS group,33 cases),Gamma nails (Gamma group,30 cases),or PFNA (PFNA group,40 cases).By the AO classification,there were 44 cases of type 31-Al,30 cases of type 31-A2 and 29 cases of type 31-A3.The 3 groups were compared in terms of incision length,operation time,intraoperative blood loss,fracture healing time,postoperative weight-bearing time,Harris scoring,and incidence of postoperative complications.Results PFNA group incurred significantly shorter incision length (5.4 ±0.5 cm) and operation time (70.8 ± 16.2 min) than DHS group (12.6 ±2.7 cm and 102.6±17.4min) and Gamma group (7.5±0.8 cmand93.0±35.9 min) (P ＜0.05).The intraoperative blood loss in PFNA group (163.2 ± 60.6 mL) was significantly less than in DHS group (280.5 ±89.8 mL) and in Gamma group (204.9 ±62.2 mL),and that in Gamma group was also significantly less than in DHS group (P ＜ O.05).PFNA group had significantly shorter weight-beating time (11.0 ± 0.8 weeks),fracture healing time(13.6 ± 1.5 weeks) and significantly higher Harris good to excellent rate (92.5％) than DHSgroup (13.3±1.0weeks,15.8 ± 1.2 weeks and 84.8％) and Gamma group (12.5±1.3 weeks,14.2 ± 1.0 weeks and 86.7％) (P ＜ 0.05).The incidence of postoperative complications in DHS group (21.2％)was significantly higher than in Gamma group(10.0％) and in PFNA group (7.5％) (P ＜ 0.05).Conclusions DHS,Gamma nail and PFNA are effective means for the treatment of intertrochanteric femoral fractures in the elderly.Intramedullary fixation,especially by PFNA,shows superiority in the clinical outcomes.

BACKGROUND:Hepatocyte transplantation as an effective method for liver failure has been confirmed by animal models and clinical application.However,limited source and poor proliferation of hepatocyte graft limit its development.Studies have shown that bone marrow mesenchymal stem cells(MSCs)have potentials to differentiate into hepatocyte and bile epithelial celts,with strong proliferation.OBJECTIVE:To explore the therapeutic effect of bone marrow MSCs transplantation on liver failure of New Zealand white rabbits.METHODS:Adult male New Zealand rabbits were treated with D-galactosamine,and 3 mL hepatocyte suspension(1×109/L)was injected into the liver of transplantation group,but the control group was injected with the same volume of culture solution with no bone marrow MSCs.Alanine aminotransferase(ALT)and aspartate aminotransferase(AST)activity was detected 48,72 hours,1,4 weeks following transplantation,and pathological detection was performed at 4 weeks.RESULTS AND CONCLUSION:The liver functional index following transplantation of bone marrow-derived MSCs transplantation was significantly decreased,and ALT and AST activity at 4 weeks was significantly less than the control group(P ＜ 0.05).At 4,the transplantation group displayed disorderly hepatic cord,hepatocyte swollen and degeneration,necrosis,accompanied by bleeding and inflammatory cell infiltration.In addition,the hepatic lobule structure was detectable,and regenerative hepatocyte increased among necrotic hepatocyte;small cells with large ratio of nucleus and cytoplasm at header,central vein and surrouding necrosis focus extended to the liver tissues.
