Objective Observing the effect of general anesthesia (GA) with remifentanil on parturients undergoing cesarean section and Apgar score of child.Methods 40 parturients were divided into two groups,GA combined remifentanil (group A,n =20) and standard GA(group B,n =20).Observe the change of hemodynamics parameter and Apgar score of child.Results In group A than in group B maternal hemodynamic index smooth,two groups of intubation after lmin SBP,DBP,HR decreased,while the5 min after intubation returned to normal.SBP DBP,HR before induction,the difference between groups was not statistically significant (P＞ 0.05),the two group after induction,SBP,DBP,HR intubation after 1 min were (120.8 ± 19.6 mm Hg,80.6 ± 11.2 mm Hg,98.1 ± 17.1 BPM),(128.1 ± 17.5 mm Hg,98.9 ± 13.8mm Hg,108.7 ± 20.7 BPM) after intubation of 5 min were (98.3 ± 24.7 mm Hg 75.3 ± 13.8 mm Hg,79.9 ±22.6 BPM),(121.5 ± 16.2 mm Hg,88.6 ± 13.7 mm Hg,110.5 ± 17.4 BPM) had a significant difference (P ＜ 0.05),neonatal 1 min,5 min Apgar score,no significant differences between the two groups (P ＞0.05).Conclusion When remifentanil is used in the general anesthesia,its inducing is smoothly and it is no significant bad effect on the newborn.

To improve the precision of image registration based on corner detection, a relative position function between multiple points to determine matching points accurately. First the corners in images are detected using Harris detector, and clustering method is used to eliminate most wrong matches after coarse screening. Then the proposed relative position function is used as a criterion of precise matching. Finally the image registration process is accomplished by affine transformation. Results show that the proposed algorithm is more effective and accurate than conventional registration algorithm.

Objective To study the feasibility of laparoscopic procedures in the treatment of ectopic pregnancy with hemorrhagic shock. Methods Laparoscopic procedures were carried out in 35 patients with ectopic pregnancy concurrent with hemorrhagic shock. Patients' blood pressures were all above 60/30 mmHg, and B-ultrasonography revealed the intra-abdominal blood loss

Objective To investigate the regulatory effect of transforming growth factor-? 1 (TGF-? 1)on the proliferation and apoptosis of human prostatic epithelial cells in vitro. Methods The primary culture was prepared by collagenase dissociation of minced prostatic tissue obtained from 8 BPH patients (53 to 70 of age) on open prostatectomy and from 5 organ donors (23 to 36).Cells were cultured in serum free prostate epithelial cell growth media and identified by immunocytochemical studies.The cells were passaged and cultured in media free of bovine pituitary extract and EGF and TGF-? 1 and EGF in different doses were then added either alone or in combination according to experimental requirement.The rate of cell proliferation was assessed by counting the cell number and by 5-bromo-2'-deoxyuridine (ELISA).Apoptosis induced by TGF-? 1 was examined by in situ transferase-mediated dUTP nick and labeling. Results The cultured cells had the typical morphological features of epithelium and stained positive for PSA and Pan-Keratin.The cells from normal prostates of young donors showed more mitogenic activity than those from BPH prostates.EGF enhanced cell proliferation whereas TGF-? 1 inhibited cell proliferation which could be reversed by increasing concentration of EGF.TGF-? 1 induced apoptosis of human prostatic epithelial cells.The effect of TGF-? 1 and EGF was concentration dependent. Conclusions TGF-? 1 is a direct physiological regulator of cell proliferation and cell apoptosis of human prostatic epithelial cells.

Objective To investigate the effect of TGF ? 1 and EGF on the proliferation of cultured human prostatic epithelial cells. Methods The primary culture was prepared by collagenase digestion of minced prostatic tissue obtained from prostatectomies of 8 benign prostatic hyperplasia(BPH) patients (aged 53 to 70) and 5 organ donors (aged 23 to 36). Cells were cultured in serum free prostatic epithelial cell growth media and identified by immunocytochemical method. The cells were passaged and cultured in media without bovine pituitary extract (BPE) and then, EGF and TGF ? 1 with different concentration were added into the culture either alone or in combination according to the experimental protocol. The cell proliferation was assessed by counting the cell number (BrdU) and ELISA. Results Cultured cells showed typical morphological features of epithelium and stained positive for PSA and Pan Keratin. After 5 7 passages cells went senescence. BPE and EGF enhanced whereas TGF ? 1 inhibited the cell proliferation and the inhibition was reversed by increasing the concentrations of EGF. The effect of both TGF ? 1 and EGF displayed concentration dependent manner. Conclusions Cell proliferation of the cultured human prostatic epithelial cells could be modulated by TGF ? 1 and EGF. These results indicated that TGF ? 1 and EGF, as the negative and positive growth factors might play an important role in the pathogenesis of BPH.

Objective: To study the diagnosis and treatment of primary hyperparathyroidism.Methods: The clinical data of 8 primary hyperparathyroidism patients(1992 2002) in our hospital were summarized and the references were reviewed.Results: It was found that primary hyperparathyroidism was liable to be misdiagnosed.Information on blood calcium,parathyroid hormone(PTH) and imaging may be helpful for diagnosis. Surgical resection(4 cases), anhydrous alcohol injection (2 cases), electron radiation (1 case) and internal medicine (1 case) were applied. Conclusion:Information on blood calcium,PTH and early imaging is helpful for diagnosis.Operation is the first choice of treatment, and for patients who can not tolerate surgery, anhydrous alcohol injection is an effective and safe treatment.

Objective: Surfactant protein A (SP-A) is protein that appears to play an important role in mammalian first-line host defense. The objective of this study was to immunolocalize SP-A in human sinonasal tissue. Method:Eleven cases of allergic rhinitis, fifteen cases of polyp and seven cases of normal middle turbinate were studied with immunohistochemistry and immunofluorescence method to detect the expression of SP-A. Result:The expression of SP-A in allergic rhinitis and polyp were dramatically higher than that in controls(P<0.05), and there was no remarkable difference in the expression of SP-A between allergic rhinitis and polyp(P>0.05). The result demonstrated that SP-A was positivly correlated with eosinophils within the basement membrane of epitheli-um(R=0.81,0.55). In the result of immunofluorescence, there was significantly higher expression SP-A in nasal mucosa of allergic rhinitis and nasal polyp than that in control group(P<0.05). Conclusion:SP-A is likely to play key roles in the inflammatory reaction process of allergic rhinitis and polyp. Its secretion in the upper airway indicates that future studies may allow manipulation of this protein and development of novel treatments for sinonasal pathology.

Aging changes of somatostatin (SS) mRNA-positive neurons in the dorsal hippocampus of old rats were studied by in situ hybridization histochemistry and image analysis. In the young rats,SS mRNA-positive cell bodies were mainly located in the pyramidal and polymorphic cell layers of the CA1 and CA2 regions, and in the strata radiatum and polymorphic cell layer of the CA3 region, and in the polymorphic cell layer of dentate gyrus. In the old rats,SS mRNA-positive cell bodies were concentrated in the polymorphic cell layer and denate gyrus. A marked decrease of number of SS mRNA-positive cell bodies and a significant increase of gray value of SS mRNA-positive cell bodies were found in the dorsal hippocampus and dentate gyrus of the old rats as compared with the young rats. No significant age difference in the sectional area of SS mRNA-positive cell bodies was observed in the dorsal hippocampus. The results showed that there were apparent changes with aging of the SS mRNA-positive cell bodies in the dorsal hippocampus of the rats. The significance of the changes remains to be studied further.
