Objective:To explore of clinical value of three-dimensional computed tomography angiography(3D-CTA) in the etiological diagnosis and management of intracranial aneurysm.Methods:One hundred and fifteen patients with spontaneous SAH admitted from September 2007 to August 2008 were examined with 3D-CTA,and were examined with digital subtracted angiography(DSA),and eighty nine patients were found suffering from intracranial aneurysm which underwent DSA.Repeated 3D-CTA was performed 1 week after clipping in eighty one patients or embolization in eignt cases.The findings of 3D-CTA were compared with the results of DSA.Results:A total of ninty seven aneurysms in eighty nine cases were detected by 3D-CTA,but DSA revealed ninty three anurysms.DSA confirmed the findings of CTA except for five cases of small anterior communicating aneurysms and three cases posterior communicating aneurysms which were demonstrated by 3D-CTA and verified by surgery but missed by DSA and four cases which were found by DSA and verified by surgery but missed by 3D-CTA.The sensitivity of 3D-CTA to diagnose the intracranial aneurysms is 95.6% and the specificity is 100% and the accuracy is 96%.The diagnose accordance rate among 3D-CTA and DSA and/or surgery is 88.1%.Conclusion:3D-CTA and 2D-DSA and/or surgery have high diagnose accordance rate,and we should combine the two diagnostic techniques to examine intracranial aneurysms accurately.

Platelet -derived growth factor (PDGF)is an important factor of promoting cell growth which has a physiological role ranging from DNA synthesis,cell mitosis inducement,promotion on a variety of extracellular matrix accumulation as well as impact on the cell phenotype and growth.Studies showed that PDGF played an important role in growth and proliferation of vascular and nerve.It has a significant effect on accelerating tissue repair and promoting healing of chronic diabetic foot ulcers.

Objective To evaluate the efficacy and adverse events of oxcarbazepine(OXC) on the children with partial epilepsy.Met-hods Sixty-four children with partial epilepsy were divided into 2 groups.Forty-one newly diagnosed patients who had never accepted standard therapy entered monotherapy group,and 23 patients who had many anti-epileptic drug(AEDs) in turn with poor efficacy served as add-on therapy group.The initial dose was 4-8 mg/(kg?d).The dosage was increased by one time every 2 weeks,and should not exceed 10 mg/(kg?d) in each time.The maintenance dose was 28-40 mg/(kg?d).With open-label autocontrol method,the efficacy and adverse events of OXC were analyzed during the first 6 months of treatment both in 2 groups.Results The effective rates were 85.4%,69.6% and 79.7%,in monotherapy,add-on therapy and total groups.The seizure free rates were 53.7%,17.4% and 40.6%.It showed that the seizure frequencies between 2 groups at 6 months after therapy were significantly difference(P0.05).The common adverse events were dizziness,headache,fatigue and nausea.Six patients had dropped out because of rashes,however,they all recovered after drug withdrawal and nonspecific therapy.Conclusion The efficacy of OXC is sustained with good safety and tolerability profiles on the treatment of children patients with partial epilepsy.

[Summary] Transplantation of human cell, tissue or organ is an effective means to cure completely the disease. Animal experiments and clinical studies have demonstrated that the efficacies of transplantation are obvious in the treatment of hypothyroidism. In recent years, thyroid stem cell transplantation has drawn much attention, embryonic stem cells, bone marrow mesenchymal stem cells and adult stem cells had also made progress in clinical investigations. Especially the embryonic stem cell transplantation has been used successfully in animal experiments. It provided a new perspective for clinical thyroid transplantation, but it also faces many problems to solve.

Objective To observe the sedative and analgesic effects of local anesthesia with midazolam and sufent-anil for patients in ophthalmologic plastic surgery. Methods A total of 160 patients (ASA I-II) were randomly divided into two group using a random number table, 80 cases in each group, groupⅠ: local anesthesia and groupⅡ: local anesthesia with midazolam (0.05 mg/kg) and sufentanil (0.1μg/kg). Values of bispectral index (BIS), systolic blood pressure (SBP), dia-stolic blood pressure (DBP), heart rate (HR), respiratory rate (RR), oxyhemoglobin saturation(SpO2) and visual analogue scale (VAS) were recorded after patients entered into the operating room, during the time of injection of local anesthesia, at the beginning of the procedure, 20 min after the surgery and after operation. It was also recorded including hypoxemia, ap-noea, restlessness, nausea and vomiting and the duration of surgery. Results There were no significant differences in age, gender, weight and duration of surgery between two groups of patients. There was a significantly lower BIS value before inject-ing local anesthesia, at the beginning of the surgery and 20 min after the surgery compared with that of time point that pa-tients entered into the operating room in groupⅡ(P<0.05). In groupⅠthere were significantly higher values of SBP, DBP and HR during the injection of local anesthesia, at the beginning of the procedure, 20 min after the beginning of the proce-dure and after the surgery than those of time point that patients entered into the operating room;the value of RR was signifi-cantly increased during the injection of local anesthesia, at the beginning of the procedure and 20 min after the beginning of the procedure than that of time point that patients entered into the operating room (P<0.05). Compared with before anesthe-sia induction, values of SBP, DBP, HR and RR were significantly decreased in groupⅡ(P<0.05). There were significantly lower levels of SBP, DBP, HR and RR during the local anesthesia injection to the time after surgery in groupⅡthan those of groupⅠ. The value of VAS was significantly higher during the time of injection of local anesthesia and during the surgery in groupⅠthan that of groupⅡ(P<0.05). There were 15 patients with restlessness in group I, which were higher than those of groupⅡ(3 patients with restlessness). There were 3 patients with nausea and 3 patients with anoxemia and no apnea in group Ⅱ. Conclusion The conscious sedation with midazolam and sufentanil is an effective anesthetic technique for patients in ophthalmo-logic plastic surgery.

Hypertriglyceridemia is one of the clinical manifestations of hypothyroidism.Besides regulating thyroid hormone axis,thyroid stimulating hormone (TSH) also has the effect on up-regulated expression of inflammatory cytokines.Synthesis of inflammatory factors can promote the expression of apolipoprotein B48 (ApoB48) in intestinal mucosal epithelial cells,suggesting that TSH may up-regulate the expression of ApoB48 by inducing inflammation; while theoratically,low-level of thyroid hormones can inhibit the synthesis of ApoB48.At the same time,since ApoB48 is the important cause of hypertriglyceridemia,there is a contradiction that it is difficult to explain the clinical phenomenon of hypertriglyceridemia induced by hypothyroidism.Therefore,hypothyroidism may affect the expression of ApoB48 by high level of TSH and low level of thyroid hormones,leading to hypertriglyceridemia.
