Objective To investigate the value of bispectral index and intracranial pressure monitoring in evaluation of postoperative consciousness and short-term prognosis in patients with severe traumatic brain injury.Methods A simple random sampling method was used in 30 cases of brain trauma coma patients in the People's Hospital of Northern Jiangsu Province from January 2014 to December 2014.Glasgow coma scale (GCS) were evaluated at intervals of 8 hours,GCS were recorded for 3 days after surgery,The bispectral index value and intracranial pressure value are recorded at the same time.According to GCS,the patients were divided into two groups,group A (3≤GCS≤5) and group B(5 < GCS≤8).The 21-days natural survival rate was counted.The Kaplan-Meier Method and Log-rank test were used to analyze the relationship between Bispectral index and intracranial pressure.Results The bispectral index value of group A was 45.3 ± 3.8,the intracranial pressure value of group A was (18.6 ± 2.8) mmHg,The bispectral index value of group B was 32.2 ± 8.2,the intracranial pressure value of group B was (33.4 ±4.6) mmHg.The 21-days survival rate of group A was 55%,and 21-days survival rate of group B was 30%.The Spearman rank correlation method was used to analyze the values.Bispectral index value was positively correlated with coma degree after operation in patients with severe traumatic brain injury,and was negatively correlated with intracranial pressure value (r =0.532,P < 0.05;r =0.521,P < 0.05).The more severer the patient's craniocerebral injury.,the more severer the condition,the higher the intracranial pressure,the lower the bispectral index value,the worse the prognosis is.Conclusion Combined monitoring of bispectral index and intracranial pressure has high application value in evaluating the coma degree and prognosis of patients with severe craniocerebral injury after operation.

Objective To observe the activities of serum peroxidase capacity,and lipid peroxidation of children from Kaschin-Beck disease (KBD) areas of Xinghai county in Qinhai province,and to explore the relationship between antioxidant capacity and KBD.Methods Sixty four KBD and forty six health subjects without KBD were chosen from KBD endemic areas,which included primary schools of Tangnaihai,Xialujuan and Qushian of Xinghai county in Qinghai province,and fifty nine age-matched healthy control subjects without KBD were from a non-KBD endemic area,Nanfan primary school of Chang'an county in Shaanxi province.Twenty patients with KBD and twenty control subjects from KBD areas and non-KBD area were extracted by simple random sampling method.2,3-DAN fluorescence technique was used to test the hair and blood selenium.The biochemical techniques were used to test the indicators of oxidative stress including malondialdehyde(MDA),antioxidant enzyme activities,total antioxidant capacity(T-AOC),serum superoxide dismutase(SOD),catalase(CAT) and glutathione peroxidase(GSHPx).ResultsAll patients with KBD had significantly lower serum GSH-Px activities[ (59.53 ± 25.23)kU/L] and selenium levels in hair[ (67.64 ± 17.28)μg/L] and blood[(36.27 ± 13.29)μg/L],respectively,than that of control subjects from KBD areas [ ( 91.88 ± 22.99 ) kU/L,( 153.32 ± 24.31 ) μg/L,( 63.06 ± 13.66) μg/L ] and nonKBD areas[ ( 122.68 ± 41.74)kU/L,(242.35 ± 38.56)μg/L,(98.93 ± 17.18)μg/L,all P < 0.05].Serum MDA levels in KBD patients[ (4.64 ± 1.11 )μmol/L] were significantly higher than that in control subjects from KBD [(3.31 ± 1.22)μmol/L] and non-KBD areas[ (3.43 ± 1.29)μmol/L,all P < 0.05].On the other hand,T-AOC,SOD and CAT activities were significantly higher in both KBD[(19.80 ± 6.64),(55.80 ± 8.14),(16.45 ± 5.61 ) kU/L] and control subjects[ (21.71 ± 8.82),(57.45 ± 6.96),(15.63 ± 9.18)kU/L] from KBD areas than that of control subjects from non-KBD area[ (13.56 ± 5.38),(42.79 ± 8.10),(6.05 ± 2.71 )kU/L,all P < 0.05 ].Hair selenium levels,blood selenium levels and GSH-Px activity of control subjects from KBD areas were,respectively,significantly lower than that in control subjects from non-KBD area(all P < 0.05).Conclusions These findings strongly confirm the evidence that KBD patients are susceptible to oxidative stress.The results also show the increase in antioxidant enzymes,which could probably be due to adaptive response to pro-oxidant in KBD state.Hence,there seems to be an imbalance between oxidant and antioxidant systems in KBD patients.

OBJECTIVETo study the anti-myeloma activity of interleukin-2 activated bone marrow (ABM).
METHODSBone marrow mononuclear cells (BMMNC) from multiple myeloma and iron-deficiency anemia patients were cultured in the presence of rIL-2. The anti-myeloma activity of ABM against U266 cells, cells expressing surface CD45, CD38, CD138, the levels of TNF-alpha and IFN-gamma in ABM culture supernatant were measured with MTT method, flow cytometry and ELISA method respectively after bone marrow was activated with rIL-2 for 24 and 72 hours.
RESULTSThe tumor-killing activities against U266 cells of ABM were significantly increased compared with that of non-activated bone marrow (NBM) at 72 hours [(69.70 +/- 26.57)% vs (43.20 +/- 12.39)%, P < 0.05] and 24 hours [(34.25 +/- 11.93)% vs (26.53 +/- 5.48)%]. The CD45(-)CD38(+)CD138(+) cells of ABM from myeloma group at 72 hours were decreased from (8.46 +/- 3.66)% to (4.79 +/- 1.56)% (P < 0.05). TNF-alpha and IFN-gamma were detectable after cultured for 24 hours in both normal control group and myeloma group and went higher at 72 hours. The level of TNF-alpha and IFN-gamma were significantly increased in ABM compared with that in NBM (P < 0.05). Meanwhile, there was a positive relationship between the level of TNF-alpha, IFN-gamma and cytotoxicity of ABM from normal control group at 24 hours and 72 hours (P < 0.05), and was a negative relationship between TNF-alpha and IFN-gamma levels and the CD45(-)CD38(+)CD138(+) cells in myeloma group at 72 hours (P < 0.05).
CONCLUSIONNormal BMMNCs activated with rIL-2 have tumor-killing activities against U266 cells. Myeloma cells and tumor burden were decreased in myeloma bone marrow after the marrow was activated with rIL-2. Production of TNF-alpha and IFN-gamma from bone marrow cells including T cells, monocyte-macrophages and NK cells activated with rIL-2 might be involved in anti-myeloma activity of ABM.

Crohn's disease (CD) is a disease with chronic inflammation of unknown etiology involving any part of the gastrointestinal tract. The incidence and prevalence of CD are increasing recently in Asia. Half of the CD patients will have intestinal complications, such as strictures or fistulas, within 20 years after diagnosis. Twenty-five percentage of CD patients have had at least one small bowel stricture and 10% have had at least one colonic stricture and lead to significant complications. Most of these patients will require at least one surgery during their lifetime. Early diagnosis and evaluation with adequate managements for the patients can prevent disability and mortality of these patient. Here, we reviewed the current incidence of CD with stricture, the etiology of stricture, and how to diagnose and manage the stricture.

OBJECTIVETo investigate the surgical treatment of thoracic ossification of the ligamentum flavum (TOLF) and analysis of the therapeutic effects.
METHODSSix patients with thoracic ossification of the ligamentum flavum were retrospectively studied from October 2006 to October 2009. All of the patients in this group were treated by en bloc hemi-articular process laminectomy. There were 4 males and 2 females, ranging in age from 45 to 66 years, averaged 55.2 years. The evaluate factors including the preoperative and postoperative JOA scores,and the function of the urinary bladder were analyzed.
RESULTSAll the 6 patients were followed after operation. The mean followed-up duration was 10.5 months, ranging from 2 to 18 months. According to JOA evaluation criteria, 4 patients got an excellent result, 1 good and 1 bad. The one patient with bad result had spinal cord compressed for too long time, and the T2-weight MRI showed nonreversible degeneration of spinal cord and combined with schizophrenia. The clinical symptoms improved with varying degrees.
CONCLUSIONThe en bloc hemi-articular process laminectomy is an effective method for ossification of the thoracic ligamentum flavum. A thorough decompression and real-time protection of the spinal cord is the key to the success of surgery.
