BACKGROUND: Researches indicate that interleukin-6 (IL-6) in blood has changed during the process of the edema and infection of spinal cord.It is found that IL-6 participates in the course of spinal cord lesion according to the further researches. It is also presumed that the IL-6 is correlated with the edema of spinal cord accompanied nervous system diseases.OBJECTIVE: To observe the effect of the receptor antagonist of the IL-6 on the traumatic edema of spinal cord, and explore the effect of IL-6 in the process of the edema of spinal cord.DESIGN: Randomized control experiment with animals as subjects.SETTING: Department of Orthopedic, Hospital Affiliated to Guangdong Medical College.MATERIALS: The experiment was completed from January to December 2004 in the Animal Experimental Center of Guangdong Medical College.Forty male Wistar rats were selected and randomly divided into the normal group, the wound group, the saline control group and the receptor antagonist of the IL-6 treated group with 10 rats in each group.METHODS: ① The receptor antagonist of the IL-6 treated group: Blast injury of the thoracic spinal cord was made by the sap pressure, and the injection with the receptor antagonist of the IL-6 was given at the injured region with microinjector. ② The wound group: There was not the procedure of administration and placement of the tube. ③ The saline control group: The IL-6 was replaced with the sterile-physiological saline solution (SPSS), and the other procedures were the same as those of the receptor antagonist of the IL-6 treated group. ④ The normal group: There was not any treatment. All rats in each group were detected with magnetic resonance. The water content in the spinal cord was determined with the dry and humid weight method, and the status of the edema of spinal cord was observed with the electron microscope and the pathological image analysis after dyeing with hematine-eosine.MAIN OUTCOME MEASURES: ① The results of the examination of the rats in each group with the magnetic resonance. ② The water content in the spinal cord of rats in each group. ③ The status of the edema of spinal cord was observed with the electron microscope and the pathological image analysis.RESULTS: All the 40 rats entered the result analysis. ① The edema of the T2 w eighting image in the receptor antagonist of the IL-6 treated group was relieved as compared with that in the wound group and the saline control group. ② The water content of the injured region in the receptor antagonist of the IL-6 treated group, the wound group and the saline control group was higher than that in the normal group [ (81.68±1.39)%, (79.72±1.49)%, (82.59±1.12)%, (77.19±0.64)% ,P ＜ 0.01].The water content of the injured region in the wound group was higher than that in the normal group(P ＜ 0.01), and the receptor antagonist of the IL-6 treated group was lower than that of the wound group (P ＜ 0.01). ③The cell body of the gray substance was contracted, the inter-space around the cell was enlarged and the nerve cells were lost in the wound group;The saline control group was not significantly different as compared with the wound group; The cellular edema, degeneration and the necrosis in the receptor antagonist of the IL-6 treated group was milder than that in the wound group.CONCLUSION: The receptor antagonist of the IL-6 has the therapeutical effect on the traumatic edema of spinal cord. The endogenous IL-6 participates in the development of the traumatic edema of spinal cord.

Stroke has become the leading cause of death in Chinese residents. As the cornerstone of the primary and secondary prevention of ischemic stroke, aspirin can prevent the occurrence and recurrence of ischemic stroke in a certain extent. However, some patients stil have vascular events after taking aspirin regularly or higher platelet aggregation rate. This phenomenon is caled aspirin resistance or aspirin low reactivity. This article reviews the occurrence, detection methods, and treatment measures of aspirin resistance in patients with ischemic stroke.

Objective: To compare the volatile compounds extracted from Rhodiola renulata respectively by HS-SPME and SD. Methods:The volatile constituents from Rhodiola crenulata were extracted respectively by HS-SPME and SD, and then the contents and the names were confirmed by GC-MS. Results:Totally 39 compounds were identified from Rhodiola crenulata by HS-SPME while 16 ones were identified by SD. Among them, 4 common compounds were detected. Conclusion: There are some differences between the two methods. Compared with SD, HS-SPME is obviously better because more volatile constituents can be extracted from the herb, furthermore, HS-SPME has notable advantages of higher retrieval matching and sensitivity.

Background:Screening of colorectal cancer (CRC) and colorectal adenoma (CRA), the precursor of CRC, is crucial for CRC prevention.It is believed that opportunistic screening of CRC in high risk population would narrow down the screening scope and save the health resources, and is suitable for the present status in China.Aims:To analyze the performance of high risk factors in predicting CRC/CRA, for exploring the feasibility of opportunistic screening for CRC in high risk population.Methods:A total of 1 862 outpatients and health examination subjects undergoing colonoscopy from Feb.2015 to Aug.2016 at the PLA 281 Hospital were recruited and asked to complete a questionnaire of high risk factors for CRC and CRA before colonoscopy.The questionnaire was designed based on the updated consensus on the screening and management of early colorectal cancer and precancerous lesion in China.Using the results of colonoscopy as gold standard, the predictive performance of high risk factors for CRC/CRA was analyzed.Results:Four hundred and sixty-eight (25.1%) individuals with high risk factors for CRC/CRA were screened out by the questionnaire.The detection rate of CRC in individuals with high risk factors was significantly higher than those without (17.5% vs.0.9%, P=0.000).The sensitivity, specificity, positive and negative predictive values of high risk factors in predicting CRC were 87.2%, 78.2%, 17.5% and 99.1%, respectively, and the missed diagnosis rate was 12.8%.For CRC/CRA, the corresponding figures were 83.2%, 87.0%, 57.3%, 96.1% and 16.8%, respectively.The risk ratios (RR) of high risk factors for CRC and CRC/CRA were 20.35 and 14.78, respectively.Conclusions:Opportunistic screening of CRC in high risk population is feasible and applicable in China under present condition.

Objective To determine the inhibitive effect of interferon-a on hepatic metastasis of colon cancer. Methods Metastatic model of human colon cancer was established by orthotopic implantation of histologically intact human tumor tissue into the colon wall of nude mice.The mice were randomly divided into 4 groups:(1)Control group(receiving saline solution only);(2)5-FU treatment group;(3) IFN-?-2b treatment group;and(4)5-FU combined with IFN-?-2b treatment group(combined group). 5-FU and IFN-?-2b were given via peritoneum injection 1 time/2 days for eight weeks.The mice were killed at nine weeks.The tumors were weighed,the microvessel density(MVD) was detected,and the liver was examined histologically in order to discover the micrometastasis. Results In control group, 5-FU group,IFN-2b group and combined group,the tumor weight was(1.53?0.78)g,(0.87?0.59)g,(0.81?0.43)g and ( 0.23?0.09)g, respectively;the tumor inhibition rate was 0,43.1%,47.1% and 84.9%, respectively;the hepatic metastasis rate was 85.7%,78.6%,21.4% and 0 respectively.MVD in IFN-? group and combined group was significant lower than that in control group and 5-FU group. Conclusions IFN-? can inhibit the growth and hepatic metastasis of orthotopic implanted human colon cancer by inhibiting the tumor angiogenesis.It may be more effective when INF-? combined with cyotoxic agents.
