Astroglia is the first cell type in the central nervous system to encounter insult after brain ischemia. Then ischemia stimulates hypertrophic and proliferative changes in astroglia and induces it produce inflammatory factors involved in the initiation of immunologic cascade. The expression of these cytokines which interact in the central nervous system can both damage and protect the brain tissue. Therefore, it is important to study astroglia and cytokines in order to find a new way to reduce inflammation insults after brain ischemia.

BACKGROUND: With the improvement of biomaterial and further recognition in aetabular revision, the main tendency is using biologic prosthesis for mild or moderate acetabular bone defect in total hip revision. OBJECTIVE: To observe the clinical effect of simple particulate bone grafting on mild or moderate acetabular bone defect in total hip revision. DESIGN, TIME AND SETTING: A retrospective case analysis. All cases were from Department of Orthopedics, Shanghai East Hospital Affiliated to Tongji University from June 2003 to June 2008. PARTICIPANTS: A total of 10 patients with mild or moderate acetabular bone defect who received total hip revision were from Department of Orthopedics, Shanghai East Hospital Affiliated to Tongji University. Among them, there were 5 male and 5 female, with an average of 58.8 years old from 43 to 77 years old. Their last replace time were 3-10 years, with an average of (7.0?0.5) years. Two of them in the last replacement used cement components, three used cementless, four used mixture, and one used dipolar artificial thigh bone. According to AAOS typing, there were 6 cases of type Ⅰ and 4 cases of type Ⅱ. The average preoperative Harris hip joint score was 40.6. METHODS: Simple particulate bone grafting combined with biologic prosthesis was used to treat the 10 patients with mild or moderate acetabular defects. All operations were at the posterolateral approach. The acetabular cup and screw fixation were performed after grafting. The postoperative effect should be evaluated by clinical and X-ray manifestations. MAIN OBJECTIVE INDEX: The bone grafting time, bleeding volume, Harris score and complications in the perioperative period were recorded. RESULTS: All patients were adopted simple particulate bone grafting combined with biologic prosthesis to reconstruct the acetabular bone defects. One acetalum cup was found loose after one month. The titanium plate combined with particulate bone grafting was used in the second revision. At 3 months after operation, the patient could walk without crutch. No complication was found in other patients. An average of 3 years following-up was obtained. The average Harris score was 87.0. Except one acetalum cup was found loose, the X-ray showed that the bed of acetabulum and particulate bone was good healing and there was no complete transparent zone. There was no patient with displacement of acetalum cup. No osteolysis in any patient. The particulate bone and host bone had a good healing. CONCLUSION: The simple particulate bone grafting is simple and effective for mild or moderate acetabular bone defects with the good follow-up result in early period.

Objective To study the relationship between helicobacter pylori(Hp) infection and iron deficiency anemia(IDA) in children. Methods The observation group contained 26 cases and control group 22 cases.Seroferroprotein(SF) and blood routine were detected.Results There was statistically significant difference in both groups on the SF,hemoglobin,red blood cellcount,mean corpuscular volume and mean corpuscular hemoglobin concentration (P0.05). Conclusion Hp infection may be related to IDA in children.

Objective To discuss the clinical effects of locking proximal humerus plate (LPHP)for humeral proximal fractures in elderly patients.Methods A total of 84 elderly patients with humeral proximal fractures were retrospectively analyzed.Patients were randomly divided into LPHP group and control group (n=42,each group).Patients in LPHP group were treated with open reduction and internal fixation using LPHP.Patients in control group were treated with open reduction and Kirschner wire fixation.All patients were followed up for 1 year and the shoulder joint function was evaluated.Results There were no significant differences in bleeding volume and the wound healing time between LPHP group and control group [(189.2±27.5) ml vs.(177.6±28.2) ml,(102.3±6.2) days vs.(99.9±6.8) days,t=1.78,1.33,P=0.079,0.105,respectively].One year after the follow-up,there were 22 cases (52.4％,22/42) with excellent clinical evaluation,18 cases (42.9％,18/42) with good clinical evaluation and 2 cases (4.8％,2/42) with poor clinical evaluation in LPHP group,and 15 cases (35.7％,15/42) with excellent clinical evaluation,22 cases (52.4％,22/42) with good clinical evaluation,and 5 cases (11.9％,5/42) with poor clinical evaluation in control group.There was a significant difference in the evaluation rate of excellent and good clinical efficacy between in LPHP group and in control group (95.2 ％ vs.88.1 ％,x2 =3.18,P 0.028).Conclusions The internal fixation using LPHP has a good clinical effect in elderly patients with humeral proximal fractures,and it can well improve the recovery of shoulder joint function.

Objective To investigate the relationship between histopathological changes of donor liver and those after liver transplantation and explore its effects on prognosis.Methods The histopathological changes of donor liver and post-transplantation live biopsy were observed in 87 cases.Results The percentage of hepatic degeneration at immediate biopsy of donor liver was 100%,the injury of sinusoid endothelial cell accounted for 41.3%,the hepatic steatosis for 18.3%and the necrosis of liver cells for 10.3%.Conclusion Most of the pathological changes of the donor liver during and after liver transplantation are reversible.The damage of the hepatic sinusoidal cells is the important criterion for the observation of ischemia reperfusion injury.Moderate and heavy hepatic steatosis can be used in the liver transplantation. After liver transplantation,if the necrosis of liver cells gradually gets serious,the risk of transplanted liver losing its function gets bigger,so the comparative observation has very important value in diagnosis.

Objective To observe the dyskinesias and motor fluctuation in patients with Parkin-son’s disease, and investigate their influential factors. Methods The detail information of dyskinesias and motor fluctuation of 63 patients with Parkinson’s disease were recorded and followed up when the of L-Dopa therapy was carried out, and all patients were assessed by using UPDRS at “on” and “off” stage, Hoehn and Yahr scale, Schwab and England living scale.The data were calculated with SPSS 10.0 statistic software. Results All patients received alone or combined L-Dopa therapy.Among the 63 patients, 11 (17.5%) were experienced dyskinesias, in which 10 show dystonia; and 36 were (57.1%) experienced motor fluctuation, in which 28 developed wearing-off.The mean daily dose of L-dopa and score of UPDRS in “off” stage were positively correlated with dyskinesias.The duration of therapy with L-dopa was positively correlated with motor fluctuation.The controlled release cabidopa/levodopa was in negative correlation. Conclusions The rate of motor fluctuation was approximately equal to the results reported in other countries.The dyskinesias was lower in occurrence and the mean daily dose of L-dopa and the disease severity should be the main influencing factors to the dyskinesias.The duration of therapy with L-dopa should be influencing factor to motor fluctuation.The main subtype of motor complications should be dystonia and wearing-off.

ObjectiveTo investigate the expression and localization of midkine (MK) in human hepatocellular carcinoma. MethodsIn situ hybridization and immunohistochemical analysis for MK were performed on samples of both tumor tissues and paratumor tissues from HCC and benign liver tumors. ResultsThe distribution and localization of the MK transcripts′ signals determined by in situ hybridization were similar to those obtained by immunohistochemical analysis. Most HCC tissues showed enhanced positive reaction within cytoplasm to both MK probe and MK immunostaining. There was no significant difference in clinicopathological parameters between MK negative and positive cases of HCC. ConclusionsHuman hepatocellular carcinoma overexpresses MK at the mRNA and protein level.

Objective To explore the clinical application of percutaneous puncture and drainage in treating pyogenic liver abscess. Methods A total of 30 patients with pyogenic liver abscess were treated with ultrasound-guided percutaneous puncture and aspiration of abscess cavity , which was followed by DSA-guided drainage tube placement together with proper washing of abscess cavity. Results Puncturing and flushing of abscess cavity was performed in two patients with < 4 cm liver abscess , and tube placement as well as drainage was carried out in the other 28 patients with > 4 cm liver abscess. No severe complications occurred. Complete cure was obtained in all the 26 patients who had no malignant tumors. Of the 4 patients with malignant tumor, cure obtained in one and death occurred in three. Conclusion Ultrasound-guided or DSA-guided percutaneous puncture and drainage therapy is technically simple, less invasive, highly safe and clinically effective treatment for pyogenic liver abscess.

Objective To study the effects of Tongxin Plaster on serum macrophage colony stimulating factor (M-CSF), homocysteine (HCY), and granules membrane protein-140 (GMP-140) of patients with angina pectoris of coronary heart disease. Methods Eighty CHD patients were randomly divided into two groups. Forty-one cases in treatment group were given acupoint application of Tongxin Plaster on acupoint Tanzhong (CV 17) and Xinshu (BL 15) 12 hours a day. Thirty-nine cases in control group were given orally Shexiangbaoxin Pill, 2 pills twice a day. The treatment course of the two groups was 3 weeks. The serum levels of M-CSF, HCY and GMP-140 were detected respectively. Results After treatment, the levels of M-CSF, HCY, GMP-140 in both groups were all decreased significantly (P 0.05). Conclusion Tongxin Plaster has good effects on antagonizing inflammatory response of coronary artery, inhibiting activation of platelets and degrading the level of homocysteine, which may be one of the mechanisms for Tongxin Plaster in treating CHD.
