Objective To study the expression changes of IL-1β、FN-α6、IFN-γ and TNFR-m18 in peripheral blood within 2 hours in epileptic mice. Methods Semi quantitative real-time PCR was used to test the mRNA expres?sion level of IL-1β、FN-α6、IFN-γand TNFR-m18 in peripheral blood from normal and pilocarpine-induced epileptic mice at different time points (10 min, 30 min, 1 h and 2 h). Results The mRNA expression level of IL-1βincreased at 30 min(1.8±0.07), 1 h(2.9±0.98)and 2 h(1.45±0.11)after pilocarpine-induced status epilepticus comparing with that of control and SE 10 min(0.81±0.09)(P<0.05). The IFN-α6 mRNA expression level was lower at 10 min(0.59±0.05, P<0.05) than that of control. IFN-γmRNA expression level was higher at 10 min(2.85±0.11) than that of control and at oth?er time points during SE(P<0.01). TNFR-m18 mRNA expression level was higher at 1h(2.84±0.15) than that of control, and at other time points during SE(P<0.01). Conclusion The immune system of epileptic state is active, the imbalance of cytokine expression in peripheral blood may be related to the immune pathological process of acute stage of epilepsy.

BACKGROUND: It is difficult to conduct the operation of ossification of ligamentum flavum (OLF) in thoracic spine, and the operation needs complecated operative skill, and unmerited disposal tends to worsen neurological dysfunction.OBJECTIVE: To analyze the operative method for OLF of thoracic spineand functional restoration.DESIGN: Case analysis.SETTING: Department of Orthopaedics, Changzheng Hospital, SecondMilitary Medical University of Chinese PLA.PARTICIPANTS: Totally 56 patients with OLF of thoracic spine, whowere treated at the Department of Orthopaedics, Changzheng Hospital fromAugust 1996 to August 2003.METHODS: The operative therapy was performed in all the patients, and the method was determined by the results of MRI and CT examination: ①The 19 patients, whose OLF in thoracic spine was focal type, and range of lesion did not exceed two segments, were treated with simple resection and decompres sion in posterior wall of vertebral canal. ②Fenestration and sledging-allocating manipulation in the whole piece unilateral lamina of vertebra were carried out in 29 cases involving more than 2 segments. ③If coplanar OLF in thoracic spine combined with protrusion of thoracic spine disc or ossification of posterior longitudinal ligament, decompression of posterior midline approach+posterior lateral approach was performed, totally 8 cases.MAIN OUTCOME MEASURES: Post-operation functional restoration was evaluated with Epstein standard, excellent: recovery of sensation and exercise was near to normal; good: spinal cord function was improved significantly, and permitted to walk with brace; fair: small partial restoration of sensory and motor function, unable to walk; bad: Inefficiency or becoming severe.RESULTS: A total of 55 cases were followed up for more than one year and 1 case only for two months after operation. ①Functional restoration: excellent: 39 cases; good: 8 cases; fair: 5 cases; bad: 4 cases. ②Symptom recovery after operation was confirmed by disappearance of tight sensation, reduction of muscular tension, relieving of numbness in order. ③The recovery was rapid for 3 to 6 months after operation. Part of patients' condition was still ameliorating during one year after operation, and rare advancement 2 years later. The recovery of complete paraplegics was bad, so was the severe paraplegia with long history. CONCLUSION: Compressive myelopathy caused by OLF in thoracic spine should be treated in an earlier period by operation. Resection and decompression of posterior wall of thoracic spine and decompression of posterior approach could be choosed according to different condition.

OBJECTIVETo explore the effect of qidong huoxue decoction (QHD) on inflammatory factors and Toll-like receptor (TLR4) mRNA expressions in acute lung injury (ALI) rats.
METHODSTotally 50 healthy male SD rats were randomly divided into the blank control group, the lipopolysaccharide (LPS) model group, low, middle, high dose QHD groups according to body weight, 10 rats in each group. Rats in low, middle, high dose QHD groups were intragastrically administered with QHD at 4, 8, and 16 mL/kg 24, 12 h before modeling and 12 h after modeling, respectively. Normal saline was intragastrically administered to rats in the blank control group and the LPS model group. An ALI rat model was established using intratracheal instillation of LPS. Rats were killed after 24-h modeling. Then the bronchoalveolar lavage fluid was prepared. Contents of TNF-α, IL-1β, and L-10 were detected using ELISA. TLR4 mRNA expressions were determined byreal time PCR.
RESULTSCompared with the blank control group, contents of TNF-α, IL-1β , and IL-10 increased (P <0. 01), TLR4 mRNA expressions also increased in the LPS model group (all P <0. 01). Compared with the LPS model group, contents of TNF-α and IL-1β decreased (P <0. 05, P <0. 01), IL-10 levels increased (P <0. 01) , TLR4 mRNA expressions were also reduced (P <0. 01), in high and middle dose QHD groups. Compared with the high dose QHD group, con- tents of TNF-α and IL-1β increased in middle and low dose QHD groups (P <0. 05); IL-10 levels decreased (P <0. 05) in the low dose QHD group(P <0. 05), TLR4 mRNA expressions also increased in the low dose QHD group (P <0. 05). Compared with the middle dose QHD group, IL-10 levels was reduced, but TLR4 mRNA expressions increased in the low dose QHD group (P <0. 05).
CONCLUSIONSQHD had the protective effect on LPS induced ALI rats. Its mechanism might be associated with inhibiting TLR4 mRNA expressions, leading to decreased pro-inflammatory cytokines such as TNF-α and IL-β, elevated anti-inflammatory cytokine IL-10, and thereby, correcting unbalanced inflammation.

Objective:Recent studies have shown that in contrast to decrease in distal gastric adenocarcinoma (DGA), incidence of adenocarcinoma of the esophagogastric junction (AEG) has increased noticeably in numerous counties. However, the reasons remain unclear. This study evaluated the possible differences in the expression of KLF4, SP1, and Cyclin D1 in AEG and DGA, and explored the potential carcinogenesis of AEG. Methods:Immunohistochemistry was performed on paraffin-embedded tissues to evaluate the pu-tative differences in the expressions of KLF4, SP1, and Cyclin D1 at protein level between AEG (n=58) and DGA (n=47). The patholog-ical significance of these markers between the two groups was also compared and analyzed. Results:The percentage of positive KLF4 expression was significantly lower in DGA than in AEG (P<0.05). Lower KLF4 expression was found both in well-or moderately dif-ferentiated cases and in poorly differentiated cases with DGA compared with their AEG counterparts (P<0.05). However, positive stain-ing for SP1 was significantly higher in DGA (P<0.05). No significant difference was found in the expression of Cyclin D1 between the two groups. Further analysis showed that in DGA, the positive expression of KLF4, SP1, and Cyclin D1 were significantly correlated with lymph node metastasis. In AEG, only Cyclin D1 expression was correlated with lymph node metastasis (P<0.05). No correlation was found among the expression of KLF4, SP1, and Cyclin D1 in AEG. In DGA, KLF4 was inversely correlated with SP1 and Cyclin D1 (r=-0.334 and r=-0.341, respectively, P<0.05), and SP1 was positively correlated with Cyclin D1 expression (r=0.340, P<0.05).Conclusion:Different expression patterns and clinicopathological significance of KLF4, SP1, and Cyclin D1 were observed between AEG and DGA, suggesting the putative difference in the carcinogenesis and progression of AEG and DGA.

BACKGROUND: Autologous blood transfusion device has been widely used in the clinic, reduces al ogeneic blood transfusion, and avoids the occurrence of blood transfusion complications, and effectively improves the patient’s blood safety, but the application of autologous blood transfusion after total hip arthroplasty has been seldom reported. OBJECTIVE: To discuss the safety and effectiveness of autologous blood transfusion after total hip arthroplasty. METHODS: 200 patients were treated by primary unilateral total hip arthroplasty from March 2013 to March 2015. They were randomly divided into two groups. 127 patients in the autologous blood transfusion group received autologous blood transfusion by a drainage tube. 73 patients in the negative pressure drainage bal group received a negative pressure drainage tube. The standard for al ogeneic blood transfusion after replacement was hemoglobin < 80 g/L. The changes in hemoglobin were compared before and 1 and 7 days after replacement between the two groups. Total drainage volume and al ogeneic blood transfusion were compared within 6 hours after replacement between the two groups. RESULTS AND CONCLUSION: There were no statistical differences in hemoglobin levels at 7 days before and after replacement, in drainage volume within 6 hours and the total drainage volume between the two groups (P >0.05). Hemoglobin levels were significantly higher in the autologous blood transfusion group than in the negative pressure drainage bal group at 1 day after replacement (P < 0.05). In the autologous blood transfusion group, autologous blood transfusion volume was averagely 324.2 mL. Al ogeneic blood transfusion volume was averagely 146.7 mL in 31 patients. No reaction was found after autologous blood transfusion. In the negative pressure drainage bal group, 49 patients received al ogeneic blood transfusion (averagely 261 mL). The volume and proportion of al ogeneic blood transfusion were significantly lower in the autologous blood transfusion group than in the negative pressure drainage bal group (P < 0.05). Among patients receiving al ogeneic blood transfusion, seven patients affected pyrogenetic reaction during blood transfusion. These findings suggested that autologous blood transfusion is simple and effective, can effectively reduce the volume and reaction of al ogeneic blood transfusion after total hip arthroplasty and avoid blood-borne diseases, with good prospects.
