Objective To approach the operative effect of dural bilaminar saturation in frontal -temporal skull defect repairs after standard decompressive craniectomy.Methods Fifty-two patients with titanium cranioplas-ty in frontal-temporal skull defect were retrospectively analyzed;27 of them adopted dural bilaminar saturation in the first standard decompressive craniectomy(test group);25 of them adopted dural monostratal saturation in the first operation (control group).The operation time,blood loss,postoperative complications in the two groups were compared. The mean operation time:the test group was (65.00 ±8.15)min and the control group was (83.00 ± 10.25)min,there was statistically significant differences between the two groups(t =7.059,P<0.05);average amount of bleeding:the test group was (55 ±8)mL and the control group was (79 ±12)mL,there was statistically significant differences between the two groups (t=8.541,P<0.05);postoperative complications:adverse reactions were noted in 4 patients of test group (14.8%),5 cases of control group (20%),there was no significant differences between the two groups (χ2 =0.016,P>0.05).Conclusion Skull repairs in second standard decompressive crani-ectomy by dural bilaminar saturation,can be shortened the operation time and lessened amount of bleeding.

Objective: To study the etiology, clinical manifestation, diagnosis, treatment and precaution of pulmonary embolism following major surgery of gastrointestinal malignant tumors. Methods: Thirty-two cases of pulmonary embolism following major surgery of gastrointestinal malignant tumors were analyzed retrospectively. Results: The most common clinical manifestations were dyspnea, thoracodynia and palpitation. The D-dimer of all cases was positive. The examination of pulmonary arteriography by spiral computed tomography might assist the diagnosis of the disease. Twenty-two patients were discharged through the treatment of oxygen therapy and anticoagulation. Six patients recovered through the treatment of assisted respiration by respirator, thrombolysis and anticoagulation. Four patients died of respiratory failure. Conclusion: The operation of gastrointestinal malignant tumors can increase the incidence of pulmonary embolism. Arteriography by spiral computed tomography and D-dimer can assist the diagnosis and thrombolysis and anticoagulation were effectivel for the treatment.

Objective To investigate the of 5-fluorouracil effects on the expression of Smad7,TGF-β receptorⅠ,Bcl-2 and Bax in keloid fibroblasts.Methods After primary culture of keloid fibroblasts,4-6 passages of cells were inoculated in 5 different concentrations of 5-fluorouracil(10,20,40,80,160μmol/L)for 24,48 and 72 hours.Proliferative ability of keloid fibroblasts was detected by MTT assay.Expression of Smad 7,TGF-βreceptorⅠ,Bcl-2 and Bax in keloid fibroblasts was measured by Western blot.Results During MTT,5-fluorouracil did not affect cell viability at 24 hour at the concentration of 10 and 20 μmol/L.Compared with the control group,no significant difference was detected(P＞0.05).At other concentrations,fibroblast death was visible in each group(P＜0.01).Western blot analysis showed that the expression of Smad7 significantly decreased and the expression of TGF-β receptor Ⅰ significantly increased in the TGF-β1 group compared with the blank control group(P＜0.0 1).5-fluorouracil could significantly enhance the expression of Smad7(P＜0.01).There was a remarkable decrease of the Bcl-2 expression and marked increase of the Bax expression in different concentrations of 5-fluorouracil compared with the control group(P＜0.05).But,5-fluorouracil did not show any effect on the synthesis of TGF-β receptor Ⅰ.Conclusion 5-fluorouracil could inhibit proliferation and induce apoptosis on human keloid fibroblasts in vitro.

Objective To observe the expression of insulin receptor mRNA in skeletal muscle and the change of oxidative stress in diabetic rats at different intensity training.Methods Sprague-Dawley rats were divided into group A(control group),group B(non-exercise group),group C(low-intensity exercise group),group D(moderate-intensity exercise group) and group E(high-intensity exercise group),6 rats in each group.A diabetic rat model was induced by injecting streptozotocin(STZ)for 4 weeks after high lipid and glucose breeding.Rats were trained for 6 weeks on a treadmill.Serum glucose and insulin,insulin resistance index(HOMA-IR),activities of SOD and GSH-Px,and MDA were detected before and after training.Expression levels of InsR mRNA in skeletal muscle were measured by RT-PCR.Results The InsR receptor mRNA expression level in three exercise groups at different intensities was 0.55?0.05,0.53?0.04,and 0.41?0.05,respectively,and was significantly higher in low and moderate intensity exercise groups than in group B (P

Objective To investigate the protective effect of transection of cervical sympathetic trunk (TCST) on the noise-induced hearing loss (NIHL) in guinea pigs. Methods Thirty-six guinea pigs were ran-domly divided into three groups (n = 12): the operation group, the sham group and the blank control group. TCST was performed in the operation group , while the cervical sympathetic trunk in the sham group was only ex-posed and separated. The auditory brainstem response (ABR) thresholds was measured. Levels of superoxide dis-mutase (SOD) and malondialdehyde (MDA) in pasma were detected before operation (T0), before noise expo-sure (T1) and on the time of stopping noise exposure (T2), respectively. The damage situation of the outer cochlear hair cells was also checked. Results (1) At the time of T2, ABR thresholds of operation group and sham group were higher than that of the blank control group (P < 0.01), and ABR thresholds of the sham group are higher than the of the operation group (P < 0.05). (2) Levels of SOD and MDA post-noise exposure (T2) were significantly different among the three groups (P < 0.05). (3) Injured hair cells were more serious in the sham group than that in the operation group. Conclusion TCST has protective effect on NIHL in guinea pigs through increasing SOD and decreasing MDA.

Objective To investigate the related risk factors for progress of the elderly frontal lobe contusions. Methods The clinical data of 118 cases of elderly frontal lobe contusions from August 2012 to August 2014 were retrospectivelyanalyzed.118 patients were given conventional therapy after admission,received dynamic review of brain CT.The progress of patients were performed surgery of frontal coronary approach,removed contusion brain tissue by bone flap of single frontal or double the frontal lobe.No progress of patients were given conventional conservative treat-ment.Selected seven indicators combining with hypertension,oral aspirin,diabetes mellitus,contrecoup injury,Cushing response,sylvian cistern exist or not and subdural hematoma did a statistical analysis.Results This group of 118 patients,68 cases (57.6%)had progress and 50 cases (42.4%)had no progress.Statistical analysis showed that oral aspirin (P =0.006 ),sylvian cistern exist or not (P =0.001 ),Cushing response (P =0.025 )were independent risk factors of progress of the elderly frontal lobe contusions.Conclusion For elderly patients with fron-tal lobe contusion,oral aspirin,sylvian cistern exist or not,whether there is any Cushing response were risk factors for deterioration of disease progression.If one or more risk factors appeared,clinical need to prevent disease progression.
