Objective To discuss the meaning of continuous intracranial pressure (ICP) monitoring in patients with severe traumatic craniocerebral injury. Methods One hundred and twenty four patients with severe craniocerebral injury treated from August 2004 to February 2011 in our hospital, were enrolled and divided randomly into ICP monitoring group (n = 62) and routine treatment group (n = 62). The patients of ICP monitoring group had adjusted treatment plan according to the changes of ICP at any time, whereas the patients in routine treatment group underwent routine neurosurgical treatment according to the doctors' experience. Results There were 7 cases of acute kidney function failure,and 11 cases of electrolyte disturbances in the ICP group.There were 15 cases of acute kidney function failure, and 25 cases of electrolyte disturbances in the routine group. The complication rate in the ICP group was lower than that in the routine group (x2 =3. 54 and 7.67 for acute kidney function failure and electrolyte disturbances respectively, Ps <0. 01). The days of mannite using were (6±2)dand (15 ±3)d, respectively; the dosage of mannite using were (749 ± 125) g and (1545 ±250) g,respectively. The good recovery and slight disability were 28 and 16 cases in the ICP group, and 13 and 9 cases in the routine group,respectively. The severe disability,vegetative state and death were 9,4 and 8 cases in the ICP group,and 17,7 and 13 cases in the routine group. The days and dosage of mannite using in the ICP group were much less than those in the routine group (t = 8. 32 and 7.41, Ps < 0. 01). The proportion of good recovery and slight disability in the ICP group were higher than those in the routine group(x2 =5. 07 and 3. 55,Ps <0.01). However, the proportion of severe disability, vegetative state and death in the ICP group were lower than those in the routine group (x2 =0.84,0.89 and 1.43, Ps < 0. 01) . Conclusion Continuous ICP monitoring in severe craniocerebral injury shows benefits in directing treatment plan adjustment, reducing complications and improving the prognosis.

Objective: To study the effects of estrogen, progestogen and mifepristone on endometrial carcinoma cell lines in vitro. Methods: The well-differentiated endometrial cancer cell line Ishikawa and moderate-differentiated endometrial cancer cell line Hec-1B were cultured in vitro. The cells were divided into four groups:control, estrogen , estrogen and progestogen , estrogen and progestogen and mifepristone, then we implanted cells in 96-well plates to search the response in distinct hormones. Results: When stimulated by estrogen for 72 hours, the growth of Ishikawa cells was significantly higher than the control, Hec-1B cells only grew higher than the control, but it was no significance in statistics. Progestogen inhibited Ishikawa cells significantly after being stimulating for 72 hours, there was the same effect on Hec-1B cells after being stimulating for 96 hours. On the base of estrogen and progestogen, we added mifepristone,cells developed after 96 hours in Ishikawa cells and cells developed after 48 hours in Hec-1B cells. Conclusion: Estrogen can cause endometrial carcinoma cell growth; progestogen inhibits the hyperplasia induced by estrogen; mifepristone antagonizes the effect of progestogen on cell growth.

Objective:To study the functional differences between the two progestrone receptor isoforms(PR-A and PR-B) in human endometrial cancer,using antisense oligodeoxynucleotide(AS-ODN) to downregulate isoform B of progestrone receptor in endometrial carcinoma cell lines, After transfection of the oligodeoxynucleotide, several kinds of hormones were added in the cells to observe the different response,whereh to study the functional differences between the two isoforms. Methods: The well-differentiated endometrial cancer cell line Ishikawa and moderate-differentiated endometrial cancer cell line Hec-1B were cultrued in vitro. The cells were transfected with antisense, sense, and scramble-ODN. After 48 hours, the expressions of two progesterone receptor isoforms were detected by Western blot using specific antibody. Then the cells were planted in 96-well plates, transfected with antisense, sense, scramble-ODN and added in several hormones to search for the response in distinct hormones and oligodeoxynucleotides. Results: After transfecting antisense-ODN, two cell lines were down-regulated in progesterone receptor isoform B,but progesterone receptor isoform A was not down-regulated,and the progesterone receptor isoform B of cells transfected with sense and scramble-ODN was not changed. When stimulated by 17?-estradiol(E2)for 72 hours,the growth of Ishikawa cells was significantly higher than that of the control, Hec-1B cells only grew higher than control,but it was to significant in statistics.R5020 inhibited Ishikawa cells significantly after stimulating for 72 hours.There was the same effect in Hec-1B cells after stimulating for 96 hours.On the bases of E2 and R5020, we added mifepristone(RU486) .The cells developed after 96 hours in Ishikawa cells and developed after 48 hours in Hec-1B cells. When PR-B was down-regulated,the stimulating effect of E2 was enhanced, but the inhibitory effect of R5020 was de-creased, RU486 antagonized R5020 weaklier than the control. Conclusion: AS-ODN directed against the human PR-B can inhibit the expression of PR-B effectively,through which the PR-A expresses predominantly. E2 can cause endometrial carcinoma cell growth, PR-B is associated with the stimulating effect of E2 in endometrial carcinoma cells. Progestin (R5020) inhibits the hyperplasia induced by E2,PR-B is involved in the inhibitory effect of R5020. RU486 antagonizes the effect of R5020,inhibiting cell growth, PR-B is involved in the antagonizing effect of RU486.

Objective To examine the expression of inhibitory chondroitin sulfate proteoglycans (CSPGs) and in-vestigate their potential effects on neural plasticity in the peri-infarct cortex and ipsilateral thalamus after focal cerebral infarction in hypertensive rats. Methods Twenty-four adult renovascular hypertensive Sprague-Dawley rats per group were subjected to permanent right middle cerebral artery occlusion(MCAO) or sham operation. Twelve rats which were se-lected randomly from per group at each time point were decapitated and their brains were removed and cut into coronal sections at 7 and 14 days post MCAO. The expression of CSPGs, NG2 and Neurocan was examined using immunostaining and western blot. Results All rats displayed neurological deficits to varying degrees and the expression of CSPGs, NG2 and full length Neurocan was increased in the peri-infarct cortex and ipsilateral thalamus at 7 and 14 days (P<0.05). However, there were no significant difference in either expression of CSPGs, NG2 and full-length Neurocan between 7 and 14 days or the expression of C-terminal fragment Neurocan at 7 and 14 days (all P>0.05). Conclusions CSPGs may play a negative role in neural plasticity through induction of inhibitory environment in the peri-infarct cortex and ipsilat-eral thalamus following focal cerebral infarction in hypertensive rats.
