ObjectiveTo observe the effect of community-based rehabilitation (CBR) on older stroke patients in ability of activities of daily living (ADL).Methods50 older stroke patients were randomly divided into the rehabilitation group and control group. The rehabilitation group was treated with motor function exercise and ADL training, while the control group only took medicine. Two groups were evaluated with Barthel index before and after treatment. ResultsScores of Barthel index on the rehabilitation group were higher than that on the control group after treatment, and there was a significantly difference between two groups (P<0.01). Conclusions CBR has the significant effect on improving ADL in older stroke patients.

Objective:To explore the clinical value of X-ray and CT in detecting unusual mediastinal mass.Methods:The chest plain films and CT scans were performed in all 9 cases .Results:Nine cases proved by operation and pathology included liposarcoma(two cases),multiple neurinoma(two cases),neuroendovrine cartinoma(two cases),endodermal sinus tumor(two cases)and thymas cacinoid (one case).Conclusion:X-ray and CT can localze the mediastinal mass,CT has more significance in detecting the internal morphology of mediastinal mass and its relationship with the surrounding tissues.But there is still a limitation for X-ray and CT in detecting the quality of some mediastinal carcinomas.

Objective To investigate the dynamic expression of the 20S proteasome in peripheral blood mononuclear cells (PBMCs) of type 2 diabetic patients without vascular complications. Methods PBMCs were prepared from 30 type 2 diabetic patients and 30 nondiabetic controls. The general indexes including weight, height and blood pressure were recorded. Fasting plasma glucose, fasting plasma insulin and glycosylated hemoglobin were measured. The protein level of the 20S proteasome was measured by Western blotting. The mRNA expression levels of the 20S proteasome β1, β2 and β5 subunits were detected by real-time PCR. Results Compared with that in the nondiabetic controls, the protein level of the 20S proteasome was significantly increased in the diabetic patients and was positively associated with glycosylated hemoglobin. Conclusion Type 2 diabetic patients without vascular complications have an increased 20S proteasome expression, the significance of which needs to be explored by further study.

OBJECTIVETo investigate the changes in the levels of monocarboxylate transporter-2 in spinal cord horn in a rat model of chronic inflammatory pain.

METHODSMale SD rats weighting 180 - 220 g were randomly divided into two groups(n = 48): normal saline group (NS group), complete Freund's adjuvant group (CFA group). Rats were given injections of CFA 100 µl in left hind paw in group CFA, and an equal volume of saline was given injection in group NS. Mechanical withdraw threshold(MWT) and thermal withdraw latency(TWL) were measured at before injection(T0 and 3 h, 1 d, 3 d, 7 d, 14 d, and 21 d after injection(T1-7). Four rats were chosen from each group at T0-7 and sacrificed, and L4-5 segments of the spinal cord horn were removed for measurement of the expression of monocarboxylate transporter-2 by Western blot analysis.

RESULTSIn CFA group, mechanical hyperalgesia and allodynia appeared on the 3 h after CFA injection, then until the day 14. The expression of monocarboxylate transporter-2 in the spinal dorsal horn of rats in CFA group was significantly higher than that in normal control group at T1-6(P <0.05). The protein level of monocarboxylate transporter-2 was apparently correlated with MWT and TWL(P <0.01 and P <0.05) in CFA group.

CONCLUSIONThe level of monocarboxylate transporter-2 in spinal dorsal horn is significantly increased in a rat model of chronic inflammatory pain and the change may involve in the formation and maintenance of central sensitization in spinal cord of chronic inflammatory uain.

Objective To explore the relation between the behavior psychology analysis of partial me-chanical injuries and the nature of death in high-falling cases, and provide reference, for such cases. Methods Of 311 death victims of high-falling injuries collected from 2008 to 2013, 205 cases were as-sociated with partial mechanical injuries. The characteristics of injury formation, preliminary crime scene traces, fatal injury of high-falling, and text messages were all retrospectively analyzed. Results Accord-ing to the investigation of preliminary crime scene traces, fatal injury of high-falling and text message, there were 86 suicide, 24 accident and 95 uncertainty in the 205 cases. According to the behavior psy-chology analysis of partial mechanical injuries, there were 80 suicide, 11 accident, and 4 homicide in the 95 uncertainty cases. Conclusion The partial mechanical injuries uncertainly caused by high-falling correlate with the manner of high-falling death. According to the behavior psychology analysis of the partial mechanical injuries in high-falling death cases, the presumption of high-falling death is usually accurate.

Objective：To study the toxicity mechanism(s) of ifosfamide(Ifo) in suspending cultured rat hepatocytes.Methods：Hepatocytes of adult rat were isolated using two-step perfusion method and cultured suspendingly. Cell viability,intracellular enzyme leakage, contents of sulfhydryl groups and MDA contents of hepatocytes were examined 3 hours after ifosfamide was administered at 5,10,20 mmol/L. Surface and ultrastructure of hepatocytes were also observed. Results：Cell viability and TSH,NPSH,PSH contents of hepatocytes significantly declined, and LDH,AST activities in media increased due to the leakage of intracellular enzymes. The decrease in PSH content was ascribed to depletion of TSH. The higher the dose was, the more serious these changes became. However, MDA contents of the hepatocytes were not found increased at any ifo dose groups. In pathological examination, “bulla" formation was found on the surface of the hepatocytes, deformation，swelling even vacuolation of mitochondria and dilation of rough，smooth endoplasmic reticulum were also observed. Conclusions：Ifo has toxic effect on suspending cultured rat hepatocytes. The decrease in sulfhydryl groups contributes to the hepatotoxicity induced by Ifo.
