Endotoxins are lipopolysaccharides ( LPS) , major component of out wall in Gram-negative bacteria. Often they are considered as "prime criminals" of triggering systemic inflaming reaction such as sepsis, bacteremia and so on. It was found in recent years that bactericidal/permeability-increasing protein, a 55kDa member of lipid-related protein family, was a kind of natural molecule of anti-infection and it has special endotoxin-neutralising activity and antibacterial activity. Comprehensive phase II/III clinical trials demonstrated the feasibility and safety of recombinant BPI. So pharmaceutical corporations are attracted to try to apply it to therapy.

To evaluate the automated segmentation algorithm for detection of intra - retinal layers to process images obtained from ultra- high resolution optical coherence tomography ( OCT ) . Graph theory and the shortest path search based on dynamic programming were applied to automatically segment the 8 intra - retinal layers. We experimentally verified the accuracy and reliability of the algorithm. The results showed that the intra-retinal layer boundaries between automated and manual segmentations matched well. The algorithm successfully segmented the intra- retinal layers in glaucoma, high myopia, and retinitis pigmentosa patients. The proposed automatic segmentation for intra-retinal layers provides a promising tool for quantitative analysis in clinical diagnosis and treatment.

Osteoid osteoma is very rarely located in the patella, and can represent a significant diagnostic challenge, resulting in a delay of treatment. Patients with osteoid osteoma of the patella often present with knee pain that is also a typical symptom of trauma or of other diseases such as arthritis, which are much more common than osteoid osteoma. We present two young male patients diagnosed with osteoid osteoma of the patella. Each of these patients had a history of intense knee pain; however, accurate diagnosis of osteoid osteoma in the patella had been delayed for more than one year. Computed tomography (CT) scans or magnetic resonance imaging (MRI) showed a circumscribed lesion of the patella in both patients, whereas X-ray examination (posteroanterior projection) was not able to detect the tumor. Different surgical procedures were performed in these patients for resection of the tumors, and the pathology findings confirmed the diagnosis of osteoid osteoma. Both patients recovered completely from surgery.

OBJECTIVETo observe the preventive effect different compatibilities of Ramulus Cinnamomi (RC) and peony in Guizhi Decoction (GD) on diabetic cardiac autonomic neuropathy (DCAN).
METHODSTotally 60 male rats were randomly divided into 5 groups, i.e., the blank control DM group, the model group, the methycobal group, the 1:1 (RC/peony) Guishao group, the 2:1 Guishao group, and the 1:2 Guishao group, 10 in each group. Rats were pretreated with corresponding drugs for 1 week, and then induced diabetes by intraperitoneal injection of STZ. Drugs were administrated by gastrogavage for 4 more weeks after STZ-injection. Enzyme-linked immunosorbent assay (ELISA) was employed to detect levels of tyrosine hydroxylase (TH), choline acetyltransferase (CHAT), nerve growth factor. (NGF), and ciliary neurotrophic factor (CNTF) in myocardial homogenates.
RESULTSAfter 4-week modeling, body weight (BW) was obviously lower, but blood glucose (BG) was higher in STZ rats than in rats of the blank control DM group. There was no statistical difference in BW or BG among the 5 groups (P >0.05). Compared with the blank control group, TH, TH/CHAT, and NGF in left ventricle and ventricular septum increased, CHAT and CNTF increased in the model group (P < 0.05, P < 0.01). Compared with the model group, TH and TH/CHAT in left ventricle decreased (P < 0.05, P < 0.01), CNTF in left ventricle increased (P < 0.05), CHAT in left ventricle and ventricular septum increased (P < 0.05, P < 0.01) in the methycobal group. TH and TH/CHAT in left ventricle and ventricular septum decreased, CNTF in left ventricle and ventricular septum increased (P < 0.05, P < 0.01), CHAT in left ventricle and ventricular septum increased (P < 0.01), NGF in ventricular septum decreased (P < 0.01) in the 1:1 Guishao group. TH/CHAT in left ventricle decreased (P < 0.01), CHAT and CNTF in left ventricle and ventricular septum increased (P < 0.05, P < 0.01) in the 1:2 Guishao group. Compared with the methycobal group, CHAT in left ventricle decreased, TH and TH/CHAT in left ventricle increased in the 2:1 Guishao group (P < 0.05, P < 0.01). TH and TH/CHAT in ventricular septum decreased (P < 0.05), CHAT and CNTF in left ventricle and ventricular septum increased (P < 0.05, P < 0.01) in the 1:1 Guishao group. Compared with the 1:2 Guishao group and the 2:1 Guishao group, CHAT in left ventricle increased, TH/CHAT in left ventricle decreased, TH and TH/CHAT in ventricular septum decreased, CHAT in ventricular septum increased, CNTF in left ventricle and ventricular septum also increased in the 1:1 Guishao group (all P < 0.01).
CONCLUSIONSSTZ model rats had autonomic neural injury, manifested as lowered vagal nerve activity and hyperactive sympathetic nerves. GD could effectively suppress hyperactive cardiac sympathetic nerves and protect the vagus. Besides, GD (1:1) showed the optimal effect in regulating the balance of cardiac autonomic nerves and could be used in early prevention of DCAN.

National Journal of Andrology 2006;12(2):167-170
Inconspicuous penis is a group of symptoms that can make penis body not be showed normally instead of a kind of simple disease. They are presented with conclude concealed penis, buried penis, webbed penis and trapped penis. Most of them are resulting from congenital abnormality except the trapped penis. The diminutive penis caused by hypospadia and intersex and micropenis resulted from endocrine disease does not belong to this category. Pathological changes of concealed penis, buried penis and webbed penis are congenital but trapped penis is caused by acquired reasons. It's not difficult to make the diagnosis by the pathological and clinical manifestations. According to different age's indication, type and severity of the disease, corresponding surgery method ought to be chosen and the curative effect can be obtained.

OBJECTIVETo explore the protective effect of baicalin against rotenone-induced injury on PC12 cells, and the po-tential mechanism of action action was also explored.
METHODPC12 cells were injured by rotenone and were treated with different concentrations (0.1, 1, 10 μmol x L(-1)) of baicalin at the same time. Cell viability was analyzed by MTT, and morphology was observed by phase-contrast microscopy. The cell apoptosis was detected by flow cytometry by Annexin V-FITC/PI staining. The intracellular ROS level was determined by fluorescence microscope with DCF-DA staining. The expression of Bcl-2, Bax and Caspase-3 was analyzed by Western blot.
RESULTThe viability of PC12 cells exposure to rotenone for 24 hour was gradually decreased with dose escalating and 1.5 μmol x L was adopted to do the following experiment. Baicalin increased cell viability, improved cell morphology and decreased intracellular ROS level. Moreover, FACS indicated baicalin attenuated the apoptosis induced by rotenone significantly. Western blot showed that Bcl-2, Bax and Caspase-3 expression in rotenone-induced PC12 cells was reversed by baicalin.
CONCLUSIONThis study has demonstrated that baicalin protects PC12 cells against rotenone-induced apoptosis, at least in part, by scavenging excessive ROS and inhibiting the mitochondrion-dependent apoptotic pathway.

Objective To explore the expression of survivin in gliomas and its clinical significance. Methods The immunohistochemistry was used to measure protein expression of survivin in 90 cases ofglioma with grade Ⅰ 30cases, gradeⅡ30 cases and gradeⅢ-Ⅳ30 cases. We also used ten normal immunohistochemistry slices resulted from decompression after traumatic brain injury as control group. Results There are survin protein expressions in glioma cytoplasm and the higher the malignancy is, the expression becomes higher. The positive rate of survivin was 16.67% with glioma grade Ⅰ(6/30), 46.67% with gradeⅡ (14/30), and 86.67 % with grade Ⅲ- Ⅳ(26/30) which had statistical significance. However, in normal cerebral tissue, the expression of survivin was negative. Conclusion Survivin expression in gliomas is related to themalignancy of the tumor and it's targeted therapy may become a new management for gliomas.
