Objective To prospectively study the minimally invasive hematoma stereotactic aspiration and the recovery of neurological deficits after conservative medical treatment alone, as well as the incidence of post-stroke depression (PSD) in patients with intracerebral hemorrhage, so as to investigate the effect of minimally invasive hernatorna stereotactic aspiration on the recovery of neurological deficits and the incidence of PSD. Methods Fifty-five patients with intracerebral hemorrhage received minimally invasive hematoma stereotactic aspiration (n =25) and conservative medical treatment (n = 30), respectively. The neurological deficits of the patients were assessed by the National Institutes of Health Stroke Scale (NIHSS) at admission, day 14 and 90. The decreased values (all compared to baseline score) of the NIHSS scores were calculated at day 14 and 90, respectively; the modified Rankin Scale (mRS) was used to assess the disabled degree at day 90; the 17-item Hamilton Depression Rating Scale (HAMD) was used to assess the PDS status at day 14 and 90. The correlation between PSD and the degrees of neurological deficit and disability in patients was analyzed. Results The decreased value of the NIHSS score in the stereotactic group at day 14 and 90 was significantly higher than that in the conservative treatment group (all P ＜0. 05), and the value of the mRS score was significantly lover than that in the conservative treatment group at day90 (P＜0. 05). The incidence and the total incidence of PSD in the stereotactic group at day 90 were significantly lover than those in the conservative treatment group (all P ＜0.05). There were significant positive correlation between HAMD and NIHSS scores and HAMD and mRS scores. Conclusions The recovery of neurological deficits was faster after the minimally invasive hematoma stereotactic aspiration. The degree of disability in patients was lower, and the incidence of PSD was also lower than that in the conservative treatment group. PSD was closely correlated with the degrees of neurological deficits and disability.

Objective:To explore the feasibilitv of stereotactic minimally invasive aspiration of small thalamic bemorrhage.Methods:Twenty-two patients with small thalamic hemowhage(5 to 10 mL)were divided into two groups:a stereotactic group(n=10)and a control group(n= 12).The patients in the stereotactic group received stereomctic minimally invasive puncture and drainage of hematomas.According to the condition,repeated infusion of urokinase(10-20 kU) into the hematoma cavities were administered 12 hours after the procedure,and the hematomas were irrigated and drained so as to removal of them completely after retaining for 2-4 hours, The appropriate symptomatic treatment was administered in the patients in both groups.National Institutes of Health Stroke Scale(NIHSS)scores were determined 14 and 30 days before and after the treatment in all the patients.The reductiom of the NIJSS scores (as compared with those before treatment)were calculated at day 14 and 30 respectively after the treatment. Results:The reductiom of the NIHSS scores in the stereotactic group at day 14 and 30 were significantly higher than those in the control group.It was suggested that the neurological functional recovery of the patients was faster after stereotmtic minimally invasive puncture and drainage of intracranial hematorna in the stereotactic group.Concision:The stereotactic minimally invasive puncture and drainage of intracranial hematoma may significantly improve the outcome in patients with small thalamic hemorrhage.

Objective To explore a simple and reliable method for intraperitoneal injection through a paravertebral approach in rabbits. Methods Sixty New Zealand rabbits were randomized into conventional group and modified groups to receive intraperitoneal injections through conventional and paravertebral approaches, respectively. In the conventional group, the injection site was on the abdominal wall 3~4 cm lateral from the umbilicus bilaterally, while that in the modified group was located dorsally at L5/L6 level 3-4 cm lateral from the midline. Abdominal CT scan was performed in the post-injection rabbits, which were sacrificed after 24 h for abdominal dissection. Results Success with a single puncture was achieved in 13 out of the 20 rabbits in the conventional group, and the rest required at least two punctures, with a mean rank sum of 23.50. With the modified approach, a single attempt was successful in all the 40 rabbits, with a mean rank sum of 34.0, showing a significant difference between the two groups (P<0.01). The success rates of a single injection differed significantly between the two groups (P<0.01). CT scan and abdominal dissection showed that the injection site with the modified approach was far away from the vital organs and large vessels with less peritoneal hyperemia and exudation. Conclusion Paravertebral intraperitoneal paracentesis is a convenient and reliable method for intraperitoneal injection in rabbits.

OBJECTIVE: To present the experience of nasal reconstruction with forehead flap. METHOD: nasal reconstruction with forehead flap were applied in eight nasal carcinoma cases after operation and 5 nasal trauma cases with defects. RESULT: These forehead flaps were alive in all patients, all incision healed in I stage, no post operative complications were found. The shapes of nose were satisfactory, there were no recurrence of tumor during 1 to 17 year follow up. CONCLUSION The method can be clinically applied for its simple procedure, reliable flap's blood supply, high survival rate and satisfied result.

Objective To examine cerebral pathologies in cerebral amyloid angiopathy in a rat model of Alzheimer's disease. Methods Rat models of Alzheimer's disease was established by stereotactic Aβ1-42 fiber injection in the bilateral hippocampus. The cognitive function of the rats was evaluated with water maze test. HE staining, Congo red staining and double-labeling indirect immunofluorescence were used to examine the dynamic distribution of Aβ fiber deposit in the brain. Results The model rats showed significant differences from the control rats in the escape latency and the times of crossing platform in waster maze test. HE staining revealed a decreased number and degeneration of the granular cells with increased glial cells in the model rats. Congo Red staining showed that the Aβ fiber was deposited gradually in the small vessels in the brain parenchyma to cause thickening, stenosis or occlusion of the small vessels. Immunofluorescence staining detected Aβ fiber migration from the parenchyma to the walls of the small arteries in the rat models. Conclusion Cerebral amyloid angiopathy is a major pathological feature in Alzheimer's disease.

OBJECTIVE: To investigate the molecular genetic mechanism of Charcot- Marie-Tooth (CMT) disease in a pedigree. METHODS: Genomic DNA was extracted from the peripheral blood of the family members of a pedigree with autosomal dominant CMT disease, and 65 candidate genes of the proband were screened using target exon capture and the next generation sequencing, and the suspicious genes were verified using Sanger sequencing. PolyPhen-2, PROVEAN and SIFT software were used to predict the function of the mutant genes, and PyMOL-1 software was used to simulate the mutant protein structure. RESULTS: A heterozygous missense mutation [c.371A>G (p.Y124C)] was detected in exon 3 of gene of the proband. This heterozygous mutation was also detected in both the proband's mother and her brother, but not in her father. Multiple sequence alignment analysis showed that tyrosine at codon 124 of GDAP1 protein was highly conserved. All the 3 prediction software predicted that the mutation was harmful. Molecular structure simulation showed a weakened interaction force between the amino acid residues at codon 124 and the surrounding amino acid residues to affect the overall stability of the protein. CONCLUSIONS The mutation of gene may be related to the pathogenesis of autosomal dominant AD-CMT in this pedigree. The newly discovered c.371A>G mutation (p.Y124C) expands the mutation spectrum of gene, but further study is needed to clarify the underlying pathogenesis.
