AIM: To study p42/p44 mitogen - activated protein kinases ( MAPK ) signal transduction pathway effect on vascular endothelial growth factor ( VEGF ) expression induced by elevated glucose concentration in cultured human retinal pigment epithelium ( hRPE) .
METHODS:hRPE cells were cultured and divided into four groups:normal glucose group (NG) (5. 6mmol/L), high glucose group ( HG1:15mmol/L D-glucose, HG2:20mmol/L D - glucose, HG3:30mmol/L D - glucose ), PD98059 group: hRPE cells were treated by an efficient and selective inhibitor PD98059 (20μmol/L) of p42/p44MAPK signal transduction pathway and solvent dimethyl sulfoxide group ( DMSO group) . The expression of VEGF and pigment epithelium derived factor ( PEDF ) mRNA was detected by RT-PCR. VEGF protein expression in cultured hRPE supernatants was detected by enzyme-linked immumosorbent assay ( ELISA) .
RUSULTS: VEGF mRNA and protein expression induced by elevated glucose concentration increased significantly. VEGF mRNA and protein expression were restrained in PD98059 group. Ratio of ( VEGF/β-actine)/( PEDF/β - actine ) in PD98059 group decreased significantly compare with that in high glucose group.
CONCLUSION: p42/p44MAPK signal transduction pathway might play a part in VEGF expression induced by elevated glucose concentration in cultured hRPE cells.

Objective To understand the relationship between clinical manifestations and Kashin-Beck disease(KBD) and their contribution to diagnosis of KBD and to construct the diagnosis model for KBD in adolescents.Methods A total of 2248 subjects under the age of 18 were collected from 6 KBD endemic and 1 non-KBD areas of the Shaanxi province in China.Analysis of 32 indicators,including gender,age,and KBD clinical indicators.Indicators of the distribution of measurement data between the two groups using t test and analysis of variance,x2 test with count data,multi-category ordered response variables Logistic regression analysis for model building.Results It showed the KBD prevalence rate in adolescent had an increasing tendency with age.Analysis of indicators between the two groups,in addition to the age factor(P < 0.05),the difference of ankle pain,knee pain,wrist movement disorder and other 5 indicators(P < 0.05) and the last bend,elbow movement disorder,syndactyly and other 9 indicators(P < 0.01 ) were statistically significant.Sixteen clinical and radiographic features in the clinical manifestations were significantly related with the clinical severity grading with KBD(P < 0.01 ).Four models on the diagnostic indictors were constructed by cumulative logit model for adolescent KBD (-21ogL,Score,Wald x2 test,P < 0.01 ).Conclusions The establishment of the diagnostic model based on their contribution of the joint involvement in systemic performance-related indicators has an important role for clinical diagnosis of KBD.

Objective To study the course of different cervical nerve segments and their related intervertebral foramen’s size so as to increase safety and decrease complications in microinvasive surgery for cervical syndrome. Methods Fifteen human cervical specimens (30 sides) were anatomically observed for the course, branches and distribution of cervical nerves. Results The diameter of intervertebral foramen ranges from 0.54 to 0.65 cm, and increases gradually from top to bottom. The vertical diameter and anteroposterior diameter between C4, C5 and C6 vertebrae are smaller, and those between C3 and C7 are larger, but the diameter line of nerve root in intervertebral foramen from up to down gradually increases. The anteversion angle between nerve root and spine cord on horizontal plane is from 15? to 19?, within a small variation, while the declination angle on coronal plane gradually decreases from C3 to C7. There exist plenty of anastomosis branches among the cervical dorsal rami. Conclusion In the range of 0.6 cm around articular process at the entrance of intervertebral foramen, it is the narrowest part, the removal of which may alleviate the pressure on nerve root and benefit spinal stability. Because of the general existence of anastomosis branches of cervical nerve, the symptoms of cervical syndrome are not completely consistent to innervation. The intervertebral foramen between C4, C5, C6 is relatively small and the diameter line of nerve root is comparatively large, so the nerve root at C4, C5, C6 is most likely to be pressed.

The action mechanism of matrix metalloproteinases-2 (MMP-2) and tissue inhibitor of metalloproteinases-2 (TIMP-2) in the genesis, development and degeneration of haemangioma was investigated by detecting their expression in the tissue of haemangioma in different phases by using the immunohistochemistry. Fifty paraffin-embedded specimens of skin capillary haemangioma were collected, which were documented in the Department of Pathology, Renmin Hospital of Wuhan University from 2000 to 2006. All samples were stained by regular HE method, and proliferative cell nuclear antigen (PCNA) was tested by immunohistochemical S-P method. The samples were classified according to the Mulliken criteria and the expression pattern of PCNA. Immunohistochemical S-P method was applied to detect the expression of MMP-2 and TIMP-2 in proliferative and degenerative phases of cutaneous capillary haemangioma, and in normal skin tissues. In combination with the detection of the expression of factor VIII-related antigen, it was verified that in haemangioma tissues, the cells expressing MMP-2 and TIMP-2 were vascular endothelial cells. The MMP-2 and TIMP-2 expression was quantitatively analyzed by image analysis system (HPIAS-1000), and one-way ANOVA(107) and SNK(q) test were done to analyze average absorbance (A) and positive area rate of immunohistochemically positive particles by using SPSS11.5. The results showed: (1) Among 50 samples of haemangioma, there were 26 proliferative haemangiomas, and 24 degenerative haemangiomas, respectively; (2) The expression of MMP-2 was weak in normal vascular endothelial cells, cytoplasm of connective tissues and extracellular matrix around blood vessels. The expression of MMP-2 in proliferative group was significantly higher than in degenerative group and control group (normal skin) (P<0.05), but there was no statistically significant difference between the latter two groups; (3) TIMP-2 was highly expressed in normal tissues, degenerative vascular endothelial cells, cytoplasm of connective tissues and extracellular matrix around blood vessels. The expression level of TIMP-2 in proliferative phase was significantly lower than in degenerative phase (P<0.05), and the expression of TIMP-2 in proliferative phase was significantly different from that in degenerative phase and normal tissues (P<0.05). It was concluded that in proliferative phase of haemangioma, MMP-2 may promote over-proliferation of endothelial cells of haemangioma, and in degenerative phase, TIMP-2 can inhibit the proliferation of endothelial cells of haemangioma. The two substances play important roles in the genesis, development and degeneration of haemangiomas.

Objective Aortic dissection is accute in occurrence along with fast change , which is inclined to to induce psy-chotic symptoms and affect the lives of patients .The study was to investigate the effects of healthcare cooperative intervention on pa-tients with psychiatric symptoms secondary to aortic dissection . Methods We established medical cooperation organization structure to clarify the division of responsibility along with a quick assessment form , a process chart and a green channel for emergencey treat-ment.The above method was applied to intervene 32 patients with psychiatric symptoms secondary to aortic dissection and observe the diagnosis time , the time from diagnosis to surgery , the remission time of psychiatric symptoms , the incidence of adverse events and the length of stay. Results 32 patients were diagnosed within 30min followed by emergency surgery within 30min after diagnosis, which was 1-2 hours shorter than the previous diagnosis and surgery preparation time .5-21 d after surgery , psychiatric symptoms have been effectively controlled.Extubation, falling out of bed, self-injury or injury and other adverse events did not occur .No patient died, and the average length of stay was 13.5d, which was 1.75d shorter than the length of stay of previous similar patients . Conclusion The healthcare cooperation method can quickly identify patients with psychiatric symptoms secondary to aortic dissection , prevent adverse events and shorten the length of stay .
