ABSTRACT
<p><b>OBJECTIVE</b>To observe the clinical effects of using the Chinese Shang Ring in circumcision children with either phimosis or redundant prepuce, and to investigate its superiority over the similar devices available.</p><p><b>METHODS</b>A total of 824 children with phimosis or redundant prepuce underwent circumcision with the Shang Ring. The clinical data were assessed concerning the duration of the procedure, incidence of post-operative complications, time of recovery and appearance of the penis.</p><p><b>RESULTS</b>The procedure duration was (2.6 +/-1.2) min, and the complications included infection in 4 (0.6%), edema in 21 (3.2%), delayed removal of the ring in 10 (1.5%), redundant and asymmetric mucosa attributable to performance in 6 (0.9%) of the cases. The wounds healed and the rings were removed at 13.4 +/- 5.8 days after circumcision, with well-smoothed incision and good cosmetic results.</p><p><b>CONCLUSION</b>Child circumcision with the Chinese Shang Ring is easy and simple in performance, with less operative time, fewer complications and better cosmetic results.</p>

Objective To describe the survival state and to investigate the risk factors of death on patients with subarachnoid hemorrhage (SAH). Methods Age, past history, number of encephalic region suffering SAH, laboratory examination indexes, therapeutic measures, complications and prognosis of 174 patients with SAH were followed-up and investigated. The survival states and risk factors of death of the patients with SAH were identified by both Kaplan-Meicr survival analysis and Cox proportional risk model. Results There were 10 patients (5.75%) losing follow-up investigation and 164 patients with SAH completed the follow-up investigation. 66 patients died and the longest follow-up invcstigation time was 5.64 years. The survival rates of 28 days, 1 year and 3-5 years were 70.60%,63.40% and 57.20% respectively. The treatment of nimotop, aneurysm occlusion treatment and aneurysm embolotherapy could decrease the death of SAH. At the same time, advanced age, the long time smoking, hyponatremia, the rising of leucocyte in acute stage, repeated hemorrhage and cerebral angio spasm were the independent risk factors to the death of patients. Conclusion Prognosis of patients with advanced age, the rising of leucocyte in acute stage, gastrointestinal blooding, hyponatremia, repeated hemorrhage and cerebral angio spasm were unfavorable. When giving patients with aneurysm, the aneurysm occlusion and embolotherapy and nimotop treatment, the death risk could be reduced.
ABSTRACT
<p><b>BACKGROUND</b>To date murine models of permanent focal cerebral ischemia have not been well characterized. The purposes of this paper were to compare three different permanent middle cerebral artery occlusion (MCAo) models with or without craniectomy, and to identify an ideal mouse model of permanent focal cerebral ischemia.</p><p><b>METHODS</b>Experiments were performed on 45 healthy adult male Kunming mice, weighing 28 to 42 g. The animals were randomly assigned to three groups (n = 15 in every group) based on surgical procedure: MCAo via the external carotid artery (ECA), MCAo via the common carotid artery (CCA), and direct ligation of the middle cerebral artery (MCA). Each day post-ischemia, the animals were scored using an eight-grade neurological function scale, and mortality was also recorded. Seven days post-ischemia, the brains were removed for lesion size determination using triphenyltetrazolium chloride staining. Correlation analysis of lesion volume and neurological score was carried out.</p><p><b>RESULTS</b>Mortality in the group receiving direct MCA ligation was lowest among the three groups, and there was a significant difference between the direct MCA ligation group and the two intraluminal occlusion groups (P < 0.05). In all groups, neurological scores gradually increased with prolongation of ischemic duration, peaking after two days, then gradually decreasing. In the direct MCA ligation group, however, neurological scores were relatively stable. There was a significant correlation between infarct volume and neurological score 7 days after MCAo in every group (all r > 0.7, P < 0.05), suggesting good reproducibility of lesion volume in the three groups, but the infarct volume was more constant in the direct MCA ligation group.</p><p><b>CONCLUSION</b>The direct ligation model of MCAo provides an optimal means of studying permanent focal cerebral ischemia, and is preferable to the models using intraluminal sutures.</p>
