Objective To discuss the diagnostic value of soluble scavenger receptor(sCD163)for the patients of malignant tumor associated with fever in early infection .Methods Collect 102 cases of patients confirmed with malignant tumor in this hospi-tal since January to December 2014 ,all the patients were examined with blood culture .102 patients were divided into two groups ac-cording to the results of blood culture :infection group (60 cases) and uninfected group (42 cases) .ELISA ,electrochemical lumines-cence and immune transmission turbidimetric methods were used to detect the levels of sCD163 ,PCT and CRP in serum ,to compare the differences in the above indicators between two groups .The receiver-operating characteristic curve (ROC curve) was applied to evaluate the application value of sCD163 in diagnosing of malignant tumor associated with fever in early infection .Results The lev-el of sCD163 ,PCT and CRP had statistically difference in two groups(P< 0 .05) ;the critical values of sCD163 、PCT and CRP were 110 .80 ng/mL ,0 .45 ng/mL ,15 .60 mg/L respectively which can suggest the patients with malignant tumor complicated with fever in early infection .The area under the curve were 0 .894 ,0 .835 ,0 .743 respectively ,among that sCD163 area was the largest ;The corresponding sensitivity were 88 .9% ,77 .9% and 88 .0% ;specificity were 77 .0% ,74 .0% and 50 .0% respectively .Conclusion Compared with PCT ,CRP ,sCD163 has more value for diagnosing the patients of malignant tumor associated with fever in early in-fection .

ObjectiveTo observe the effectiveness of collagen sponge for reducing volume of drainage after surgery for lumbar spinal stenosis. MethodsOne hundred and eighty-six patients who suffered from lumbar spinal stenosis were divided into two groups by random digits table method. The test group(96 cases) used collagen sponge to cover dura mater before placing drainage tube,the control group (90 cases) was treated without collagen sponge. The volume of drainage at 1,12,24 h after surgery were observed, the blood routine test was carried out at before and 48 h after surgery and the volume and ratio of blood transfusion after surgery was also measured and compared between the two groups. ResultsThe volume of drainage were significantly decreased in the test group compared with the control group at 1,12,24h after surgery [( 106.11 ± 20.02 ) ml vs. ( 127.02 ± 25.09) ml, (236.12 ± 34.06) ml vs. (327.31 ± 51.21 )ml, (355.16 ± 49.03 ) ml vs.( 506.36 ± 85.29 ) ml](P ＜ 0.05 ). The volume and the ratio of blood transfusion in the test group were ( 176.27 ± 21.37) ml and 10.42％(10/96) ,which were greatly lower than those in the control group[(445.94 ±24.56) ml and 32.22％ (29/90)](P ＜0.05). The number of RBC and the concentration of Hb were (2.96 ± 0.45 ) × 1012/L and ( 106.75 ± 7.30) g/L, differently in the test group at 48 h after surgery,which were increased significantly compared with the control group[(2.35 + 0.57) × 1012/Land (90.45 ± 5.10) g/L](P ＜ 0.05 ). ConclusionsCollagen sponge provides rapid ,effective and durable hemostasis and decreases the leak of cerebrospinal fluid after surgery for lumbar spinal stenosis. It can be used as an effective and economic method to reduce the volume of drainage after surgery.

Objective To investigate dynamic changes of plasma D-dimer, C-reactive protein (CRP) and fasting plas?ma glucose (FBG) levels in elderly patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) combined with type 2 diabetes mellitus. Methods AECOPD group (n=65) was used as A group, AECOPD combined with type 2 diabetes mellitus group (n=65) was used as B group. Levels of D-dimer, CRP and FBG were observed and compared between two groups in the first day, the 3rd day, the 7th day and the 14th day after hospital admission. The correlation be?tween D-dimer, CRP and FBG was analyzed. Logistic regression analysis was used to estimate the factors affecting increased plasma levels of D-dimer. Results Levels of D-dimer, CRP and FBG were significantly higher in B group than those of A group in the first day, the 3rd day, the 7th after hospital admission (P<0.01). Values of D-dimer and CRP were declined ob?viously in A group in the 7th day after hospital admission, but in B group they were declined obviously until the 14th day. There was no significant difference in FBG of A group. The level of FBG was significantly decreased in B group. There was a positive correlation between D-dimer, CRP and FBG (P<0.05). Logistic regression analysis showed that CRP, FBG, p(O2) and age were the influence factors for the increased levels of D-dimer. Conclusion In elderly patients with AECOPD com?bined with type 2 diabetes mellitus, we should pay attention to anti-inflammatory and controlling blood sugar, and the dy?namic monitoring levels of D-dimer, which helps to improve the prognosis for patients with AECOPD, and reduce mortality.

BACKGROUND: The content of aluminium generally increases in the cerebral cells of patients with senile dementia. Aluminium poisoning in brain has inner link with senile dementia. Naloxone is the specific antagonist of opioid receptor, which can be applied in the treatment of senile dementia according to foreign reports.OBJECTIVE: To investigate protective effects of naloxone on aluminium trichloride-induced memory impairment of senescence-accelerated mice and its mechanism.DESIGN: Randomized controlled trial.SETTING: Jilin Medical College.MATERIALS: The experiment was completed in Laboratory of Pharmacology of Jilin Medical College (formerly the Jilin Military Medical College) from February 2001 to February 2003. A total of 100 healthy adult Kunming mice were selected and randomly divided into 5 groups: control group, model group, naloxone 0.1 mg/kg group, naloxone 0.3 mg/kg group and naloxone 0.9 mg/kg group, with 20 in each group. Except the control group, subcutaneous injection with 70 mg/kg aluminium trichloride was given to the mouse in each group once a day for continuous 7 days; besides this, intraperitoneal injection with 0.1, 0.3, 0.9 mg/kg naloxone was given to the mouse in naloxone groups and the same amount of physiological saline was given to the mouse in the control group.METHODS: The methods of jumping stand and escaping dark were conducted to detect learning ability and memory of mice. Meanwhile, the content of malondialdhehyde in liver and mono-amine oxidase B in brain of mice were also detect.MAIN OUTCOME MEASURES: ① Results of jumping stand experiment of aluminium trichloride-induced model of senescence. ② Results of escaping dark experiment of aluminium trichloride-induced model of senescence. ③ Comparison of malondialdhehyde and mono-amine oxidase B among each group.RESULTS: ① Results of jumping stand experiment of aluminium trichloride-induced model of senescence: Compared withmodel group, the frequency of electric shocks suffered by aluminium trichloride mice and the amount of suffered animals within 5 minutes significantly decreased in control group and naloxone 0.1, 0.3, 0.9 mg/kg groups. The experiment was repeated 24 hours later, naloxone could significantly prolong the latency of the mouse jumping down from the platform for the first time (P ＜ 0.01).Meanwhile, naloxone could decrease the amount and the frequency of mist&es of aluminium trichloride mouse within 3 minutes (P ＜ 0.01). ② Results of escaping dark experiment of aluminium trichloride-induced model of senescence: Compared with model group, the latency of aluminium trichloride mouse entering dark box was significantly prolonged and the frequency of electric shocks suffered by aluminium trichloride mice obviously increased in control group and naloxone 0.1, 0.3, 0.9 mg/kg groups (P＜0.01). ③ Comparison of malondialdhehyde and mono-amine oxidase B among each group: Malondialdhehyde was more in model group than in naloxone groups (P＜0.01). Mono-amine oxidase B was more in model group than in the other groups (P＜0.01).CONCLUSION: Naloxone has protective effects on aluminium trichlorideinduced memory impairment of senescence-accelerated mice, which can improve learning ability and memory. The mechanism is probably relevant to the effects of decrease of mono-amine oxidase B and elimination of lipid peroxide.

One hundred and five patients with non-ST segment elevation acute coronary syndrome were followed up for 1 year.They were assigned to the event group or non-event group according to the presence of endpoint events(cardiac death and nonfatM myocardial infarction).B-type natriuretic peptide level was measured at 30 days and 1 year and compared between the two groups.The results showed that the level of B-type natriuretic peptide was higher in the event group[(235±107)μg/L vs(154±49)μg/L at 30 days;(259±100)μg/L vs(143±57)μg/L at 1 year].Thus,B-type natriuretic peptide is an important prognostic factor for patients with non-ST segment elevation acute coronary syndrome.
