The expression of transforming growth factor-beta1 (TGF-beta1) in placental tissue of pregnancy-induced hypertension (PIH) and the relationship between the level of expression of TGF-beta1 and the amount of vascular cell adhesion molecule-1 (VCAM-1) in serum was studied. Immunohistochemistry ABC was used to detect the expression and distribution of TGF-beta1 in placental tissues in 40 PIH women and 20 normal pregnancy women. High resolution pathological image analysis system was used to determine the quality of TGF-beta1. The VCAM-1 in serum was examined by enzyme linked immunoabsorbent assay (ELISA). The results showed that TGF-beta1 could be express in syncytiotrophoblast. The levels of TGF-beta1 expression in placental tissues of the patients with moderate and severe PIH were significantly higher (P < 0.05), while the serum VCAM-1 was significantly lower than in normal group (P < 0.01). There was a significant positive correlation between the expression of TGF-beta1 in placental tissues and the serum VCAM-1 (r = 0.969, P < 0.01). It was concluded that the level of TGF-beta1 expression in PIH was increased and was positively correlated with the amount of serum VCAM-1, indicating that they might be involved in the pathogenesis of PIH.

The expression of endothelial nitric oxide synthase traffic inducer (NOSTRIN) in the placenta of the patients with pregnancy induced hypertension (PIH) was detected and its role in the pathogenesis of PIH was studied. The pathological changes in placental vessels were observed by HE staining. NO2-/NO3-, the stable metabolic end products of NO, was measured with nitrate reductase. The eNOS activity in placental tissues was assayed by spectrophotometry. Western blot analysis was applied to detect NOSTRIN expression. The incidence of thickening and fibronoid necrosis of placental vessels was significantly higher in women with PIH than in the normal group (P < 0.01). The levels of placental NO2-/NO3- in PIH patients (27.53 +/- 7.48 micromol/mg) were significantly lower than in normal group (54.27 +/- 9.53 micromol/mg, P < 0.01). The activity of eNOS was significantly decreased in PIH group (12.826 +/- 3.61 U/mg) as compared with that in normal group (21.72 +/- 3.83 U/mg, P < 0.01). Western blot analysis revealed that both groups expressed 58 kD NOSTRIN, but the protein level was significantly higher in women with PIH than in the normal group (P < 0.01). A significant negative correlation existed between the expression of NOSTRIN protein and the activity of eNOS in placental tissue of women with PIH (r = -0.57, P < 0.01). It was concluded that the level of NOSTRIN expression in placenta of women with PIH was increased, which may play an important role in the pathogenesis of PIH.

The expression of endothelial nitric oxide synthase traffic inducer (NOSTRIN) was examined in the umbilical vessels of the patients with pre-eclampsia (PE) to explore its possible role in the pathogenesis of PE. The NOSTRIN mRNA in umbilical tissues was determined by RT-PCR. The eNOS activity in umbilical vessels was spectrophotometrically detected. NO2-/NO3-, the stable metabolic end products of NO, was measured by using nitrate reductase. RT-PCR showed that the expression level of NOSTRIN was significantly higher in women with PE than in the normal group (P<0.01). The activity of eNOS was significantly decreased in PE group [(12.83+/-3.61) U/mg] than in normal group [(21.72+/-3.83) U/mg] (P<0.01). The level of NO2-/NO3- in PE patients (27.53+/-7.48) micromol/mg was significantly lower than that of normal group (54.27+/-9.53) micromol/mg (P<0.01). The significant negative correlation existed between the expression of NOSTRIN and the activity of eNOS in umbilical vessels of women with PE (r=-0.58, P<0.01). It was concluded that the level of NOSTRIN expression was increased in umbilical vessel of women with PE, indicating that it may be involved in the pathogenesis of PE.

To investigate the expressions of placental growth factor (PLGF) in placenta with hypertensive disorders of pregnancy (HDP), 45 women with HDP and 20 normally pregnant women were studied. Among 45 women with HDP, there were 23 cases of severe preeclampsia and one case of eclampsia. The location and level of PLGF proteins was determined by immunohistochemistry and Western blot. The expression of PLGF mRNA in placenta was assessed by reverse transcriptional-polymerase chain reaction (RT-PCR). The results showed that: (1) The distribution of PLGF in placenta with HDP was similar to normal one, which was mainly in the cytoplasm of villous syncytiotrophoblast and villous stroma; (2) The expression of PLGF protein was significantly decreased in placentas with mild and severe preeclampsia compared to the normal ones (0.3 +/- 0.4 vs 0.6 +/- 0.4, 0.2 +/- 0.5 vs 0.6 +/- 0.4, P < 0.01). There were no differences between the gestational hypertension placenta and normal one (0.5 +/- 0.6 vs 0.6 +/- 0.4, P > 0.05); (3) The transcription levels of the PLGF mRNA in placentas with preeclampsia were significantly lower than in normal groups (3.33 +/- 0.39 vs 4.87 +/- 0.60, 1.97 +/- 0.29 vs 4.87 +/- 0.60, P < 0.01), and no differences were found between the gestational hypertension placenta and normal groups. These findings suggest that the abnormal expression of PLGF in placentas is related to the pathogenesis of HDP.

Objective To explore the microsurgery methods in patients with early intracranial aneurysm rupture. Methods Sixty-seven patients with early intracranial aneurysm rupture received the emergency microsurgery after releasing cerebrospinal fluid from improved Paine point via pterion craniotomy. Thirty-nine patients received surgery within 1 d after intracranial aneurysm rupture, and the other 28 patients were within 1-3 d. Results The therapeutic effect was evaluated by Glasgow outcome score (GOS) at discharge. Among the 45 patients with Hunt-Hess Ⅰ-Ⅲ grade, cure was in 41 cases, improved in 4 cases. Among the 22 patients with Hunt-HessⅣ-Ⅴgrade, cure was in 6 cases, improved in 6 cases, moderate disability in 4 cases, severe disability in 1 case, and death was in 5 cases. Conclusions The microsurgery of clipping aneurysm directly via pterion approach is still by far the most reliable treatment. And releasing cerebrospinal fluid from improved Paine points can effectively reduce the acute brain swelling of early operation, which will make it an effective adjuvant therapy to emergency microsurgery of clipping aneurysm.

OBJECTIVE To optimize the parameters of passive cutaneous anaphylaxis(PCA)in rats immunized by ovalbumin(OVA). METHODS 1-2 month-old Sprague-Dawley rats were immu?nized by ip injection of OVA(0.2,1.0 and 5.0 mg per rat)mixed with complete Freund′s adjuvant once every other day 3 times. Serum was collected on the 12th-16th days after final immunization. Then the rats were intracutaneously injected with sensitized serum and then stimulated by iv injection of the same dose of OVA mixed with Evans blue after a latent period of 0.5,1.5,3,6,12,24,36,48 and 60 h. Finally,the diameters of blue spots in the skin were measured at stimulation. RESULTS Serum total-IgE(T-IgE)and OVA-specific IgE(sIgE)levels increased significantly and reached the peak on the 3rd-7th days and 12th-16th days after final immunization,respectively. There was no correlation between the serum T-IgE level and OVA-sIgE level when the rats were immunized with OVA at OVA 0.2-5.0 mg per rat. The rats experienced PCA after injection of OVA 1.0 and 5.0 mg per rat. Diameters of blue spots in the skin reached the maximum value after rats were sensitized for 0.5-3 h. Moreover,the shape,color and size of blue spots were better 30-60 min after stimulation. CONCLUSION Optimized PCA is as follows:1-2 month-old rats are immunized on the 1st,3rd and 5th days by ip injection of OVA 1.0-5.0 mg. The immunizing serum is collected at 12-16 d after final immunization. The rats are stimulated by OVA and Evans blue after a latent period of 0.5-3 h. Diameters of blue spots in rats′ skin are then measured 30-60 min after stimulation.

To study the expression of placental isoferritin (PLF) in placental tissue of pregnancy-induced hypertension (PIH) and the relationship between the level of expression of PLF and the amount of vascular cell adhesion molecule-1 (VCAM-1) in serum, immunohistochemical technique was used to detect the expression of PLF in placenta tissue in 45 PIH patients (PIH group) and 15 normal pregnant women (normal group). High resolution pathological image analysis system (HPIAS-100) was employed to determine the quantity of PLF. The VCAM-1 in serum was examined by enzyme linked immunoabsorbent assay (ELISA). The results showed that the levels of PLF expressions in moderate and severe PIH patients were significantly lower than that of normal group (P < 0.01). The serum VCAM-1 was significantly decreased in PIH group (1310 +/- 177 rho/ng/ml) than that of normal group (609 +/- 72 rho/ng/ml, P < 0.01). The significant negative correlation existed between the expression of PLF in placental tissue and the serum VACM-1 (r = -0.58, P < 0.01). It was concluded that the level of PLF expression in PIH decreases and is negatively correlated with the amount of serum VCAM-1, indicating that these may be involved in the pathogenesis of PIH.
