Intraspinal tumors with kinds of pathological type are common in clinic, whose first option of the treatment is the surgical resection.In recent years, neurosurgeons pay more attention to the postoperative stability of spine biomechanics on the basis of the total resection of the tumors.This paper reviews the approaches in intraspinal tumors resection and the methods of the reconstruction of spinal stability postoperatively which influence the stability of spine biomechanics most.

Objective To evaluate the effect of various rewarming regimes on rectal temperature and hemodynamic parameters of dogs after open abdominal injury and seawater immersion. Method 30 healthy dogs were subjected to open abdominal injury and 2-hour seawater immersion. Then dogs were divided into three groups: group A (n=10) received no special warming treatment, in group B(n=10) electric blanket was used to warm up to 42℃, in group C (n=10) animals were warmed by 1/3 saline solution in 42℃ for 20 minutes and continuous perfusion of the abdominal cavity with 1/2 saline solution for 2 hours. The changes in body temperature, heart rate, MAP, CVP and CO were observed before and after rescue. Results The results of group A were not satisfactory. The rectal temperature, MAP, HR and CO were not recovered to normal after 6 hours of treatment. and the rectal temperature was 34.8℃ after 6 hours. The rectal temperature rose to 36.9℃ after being rewarmed with an electric blanket in group B. The result was better than that of group A. But there was tachycardia. The effects of rewarming from hypothermia in group C was satisfied. All hemodynamic parameters and rectal temperature recovered after 4 hours treatment. Conclusion Cold seawater immersion after open abdominal injury would result to hypothermia, and intra-corporeal rewarming should be the optional treatment.

Objective To evaluate the effect of seawater immersion on hemodynamics and pathological changes in dogs with perforating injury of the intestine. Methods Thirty healthy adult dogs were subjected to perforating injury of the intestine. Ten injured dogs were immersed in artificial seawater after the injury. An equal number of injured dogs were immersed in normal saline solution. Control group dogs (n=10) were not subjected to salt water immersion. Hemodynamical and pathological changes were observed at different time intervals after injury. Results Obvious hemodynamic disorder and serious pathological changes were found after seawater immersion. Normal saline solution group and control group dogs did not show obvious disorders in hemodynamics and pathology. Conclusion Seawater immersion is one of the main factors leading to the disturbance in hemodynamic and pathological changes after perforating injury of the intestine.

Objective To investigate the effect of anomalous pancreaticobiliary ductal union on the injuries of pancreas.Methods 10 health cats were treated by a 4～6 cm incision in biliary and pancreatic duct adjacent to duodenum, and interrupted suture was made to induce the model of anomalous pancreaticobiliary ductal union.The pancreatic tissues were harvested during model induction and 6 months after model induction,and histopathological changes were evaluated by electron microscopic examination and the level of maleic dialdehyde (MDA) were determined.Results Seven out of 10 cats survived surgery and remained alive for 6 months.6 months later,the pancreas appeared to be in the color of dark red and hyperemia,edema was present.Dilated pancreatic duct could be found in three of them.Light microscopic examination suggested there was inflammatory cell infiltration in the pancreas in 3 cats;mesenchymal vascular proliferation and white cell adhesion was present in the pancreas in 4 cats.Electron microscopic examination suggested rough endoplasmic reticulum expanding in the shape of pool,swelling mitochondria disaggregated and increased in number,Golgi complex became well developed.The preoperative level of MDA in pancreatic tissue was (1.23±0.7 ) nmol/mg prot,which increased to (2.90±1.9 ) nmol/mg prot 6 months later with statistically significant difference (F=4.80,P=0.0215 ).Conclusions This animal model demonstrated that anomalous pancreaticobiliary ductal union may cause injury to the pancreas,and antioxidant treatment may alleviate this injury.

Objective To explore the differences of curative effect and short-term prognosis to severe traumatic brain injury patients with three different early postoperative nutritional supports.Methods A retrospective study was performed on 60 severe traumatic brain injury patients received in Neurosurgical Intensive Care Unit of Northern Jiangsu People's Hospital from July 2014 to July 2016.A total of 60 cases were randomly divided into the early enteral nutrition support therapy group,the early parenteral nutrition group,and the early compound nutrition group.The clinical indicators such as basic clinical characteristics before treatment,the nutrition data in two weeks,the length of stay in the Neurosurgical Intensive Care Unit,complications and GCS scores between the three groups were observed and analyzed.Results The indicators of early compound nutrition group were fasting blood-glucose (5.74 ± 0.64) mmol/L,prealbumin(203.80 ± 10.45) mg/L,total serum protein(61.99 ± 1.34) g/L,blood hemoglobin (114.53 ± 2.69) g/L,C-reactive protein(0.37 ± 0.06) mg/dl.The length of stay in Neurosurgical Intensive Care Unit was (11.6 ± 0.42) days in the compound nutrition group while those in the early enteral nutrition group was (13.20 ±0.42) days and those in the early parenteral nutrition group was(14.65 ± 0.42) days.The postoperative complications of the compound nutrition group were significantly lower than other two groups.The GCS scores of early compound nutrition group was(11.40 ± 1.60),which was the best in three groups.The differences were statistically significant (P ＜ 0.05).Conclusions Early compound nutrition support has an exact curative effect on postoperative severe traumatic brain injury patients in Neurosurgical Intensive Care Unit.It can obviously improve the nutrition status of patients with less complications,shorter length of stay in Neurosurgical Intensive Care Unit,higher safety and lower degree of coma,worth clinical promotion.

Objective To evaluate the diagnostic value of MSCT in small bowel obstruction and related complications caused by diverticulitis.Methods Clinical data and CT findings of 13 patients with diverticulitis and related complications were reviewed.The imaging findings of diverticulitis were calculated and compared with those in other 20 cases without intestinal obstruction.Results Among the 1 3 cases with diverticulitis,8 occurred in the j ej unum and other 5 in ileum.CT revealed the diverticulitis in all patients as a predominantly cylindrical expansion in communication with the adjacent small bowel.CT showed intraluminal intestinal contents and little air bubbles in 3 cases with simple diverticulitis,thickening of the appendix lumen in 2 cases with perforated diverticulitis, and annular high-density in lumen in 2 cases with diverticulitis and bezoar.CT also showed diverticulitis with volvulus in 6 cases as mesenteric swirling.The average thickness of diverticula were (3.06±0.31)mm,and the average volume of diverticula were (98.98±38.59)cm3 , exhibting statistically significant differences between diverticulitis and control groups (P value were 0.000 and 0.000).Conclusion MSCT is helpful for the diagnosis of small bowel obstruction and related complications caused by diverticulitis.

Objective To evaluate the changes in water, electrolyte and acid-base balance after seawater immersion in cases of open abdominal trauma associated with intestinal rupture, and to obtain a theoretical basis for the early treatment of open abdominal injury with intestinal rupture in naval combat. Methods A canine model of open abdominal trauma with intestinal rupture was established in 26 healthy adult dogs, and they were divided randomly into three groups. All animals were subjected to abdominal wall incision and intestinal rupture. Seawater immersion group(n=10) was immersed into artificial seawater after trauma; normal saline solution group(n=6) was immersed into normal saline solution after trauma; control group (n=10) had no immersion. The 3 groups were observed for changes in water, electrolyte and acid-base balance, and the results were analysed and compared. Results Signficant disturbance of water, electrolyte and acid-base imbalance were observed in the seawater immersion groups, but no significant changes of these parameters were seen in the control group and normal saline group. Conclusion Seawater immersion is the main factor leading to the disturbance of body metabolism after open abdominal trauma with intestinal rupture.

Objective To compare the clinical and pathological differences between IgM nephropathy (IgMN) and IgA nephropathy (IgAN) in children. Methods Clinical manifestations, laboratory examination results, and renal patholog-ical data from 38 children with IgMN and 40 children with IgAN were compared. Results The mean age of onset in IgMN group was younger than that in IgAN group (P<0.05), the mean course before renal biopsy of IgMN group was longer than that of IgAN group (P<0.05), but the incidence of gross hematuria, the level of urinary IgG and albumin, and the incidence of severe glomerular injury were all higher in IgAN group than those in IgMN group (P<0.05). In IgMN group, the level of serum albumin was lower and the urine albumin was higher in the cases with severe glomerular injury than those in the cases without severe glomerular injury (P<0.05);there were more males in those cases with sever glomerular injuries;the incidences of gross hematuria, the level of urine albumin and NAG, and the abnormal basement membrane thickness was higher in the cases with severe tubular injury than those in the cases without severe tubular injury (P<0.05). However, the incidence of severe glomerular injury had no signiifcant difference between the cases with severe and without severe renal tubular injury (P>0.05). In IgAN group, the incidence of proteinuria, RBC casts in tubular, C3 and ifbrinogen deposition, and foot process effacement were higher in the cases with severe glomerular injury than those in the cases without severe glomerular injury (P<0.05); the degree of impairment of renal function, the incidence of severe mesangial cell proliferation, and glomerular sclerosis were more serious in the cases with severe tubular injury than those in the cases without severe tubular injury (P<0.05). Conclusions The clinical and pathological features are different between IgMN and IgAN in children. The renal damage is less in IgMN than that in IgAN children. Different from IgAN children, there is no parallel relationship between tubular and glomerular injury in IgMN children.
