Objective:To study the antihyperglycemic effect of water soluble polysaccharides (MCW) and alkaline soluble polysaccharides (MCB) from Momordica charantia L. on streptozotocin-induced diabetic mice. Method:Twelve mice were selected randomly as control, while the other l08 mice were injected with STZ 200 mg/kg?bw to induce diabetes.The diabetic mice were divided into 4 groups,the model, MCW (300 mg/kg bw), MCB (300 mg/kg bw), Gilbenclamide (15 mg/kg bw). The above components were administered intragastrically for 10 d and then blood samples were taken to determine concentrations of serum glucose and insulin. Results: The blood glucose levels could be obviously decreased by MCW and MCB in the diabetic mice. MCB has the best antihyperglycemic effect, in terms of improving the serum insulin level and decreasing the blood glucose level of diabetic mice. Conclusion:The polysaccharides from Momordica charantia can repair the injured pancreatic islet tissues and enhance insulin secretion so as to reduce blood glucose level of the diabetic mice.

Objective To evaluate the clinical value of midfrontal keyhole approach for the treatment of severe intra-ventricular hematoma. Methods The clinical data of 21 cases of severe intraventricular hemorrhage through midfrontal key-hole approach were analyzed retrospectively. Results Both inside and outside intraventricular hematoma were satisfied cleared. The GCS score and intraventricular hemorrhage Graeb score were improved. There were complications after opera-tion including 1 patient with diffuse brain swelling, 3 patients with cerebral vasospasm, 1 patient with intracranial infection, and seven patients with pulmonary infection. Follow-up schedules included 1-6 months. According to ADL score, 5 patients recovered well, 9 patients were moderately disabled, 3 were severely disabled, 1 was in a vegetative state and 3 died. Conclu-sion The intraventricular hematoma can be removed through midfrontal keyhole approach. The obstructive hydrocephalus can be relieved, the secondary brain damage was reduced and the prognosis was improved in patients.

Objective: To study the surgical strategy and clinical efficacy of hypertensive basal ganglia hematomas via transsylvian transinsular approach individually. Methods: The clinical data of 45 patients with hypertensive basal ganglia hematomas underwent microsurgical treatment with different sylvian anatomical points in Jianhu Hospital Affiliated to Nantong University from October 2014 to June 2016 were retrospectively analyzed. Results: The anterior hematomas was dissected through anterior point of lateral fissure, accounted for 66.7%(30 cases), the posterior hematoma was dissected through rolandic points under lateral fissure, accounted for 22.2%(10 cases), the long axis type hematoma was dissected between the anterior point of the lateral fissure and the lower rolandic point, accounted for 11.1%(5 cases). The postoperative CT scan showed that 42 cases were removed the hematomas for more than 90.0%, 3 cases were removed the hematomas for more than 75.0%, there was no postoperative rebleeding.According to GOS score, 14 cases returned to preoperative life status, 20 cases recovered sufficiently to return to family life, 9 cases could ambulate with a crotch but needed assistance, one case showed vegetative survival, one patient died. Conclusion Transsylvian transinsular approach via individual sylvian anatomical point should be advocated to remove basal ganglia hematomas, and it has the advantages of minimally invasion, high hematoma evacuation rate, low rebleeding rate, good neurological recovery and so on.
