Objective To observe the effect of vinpocetine on monoamine transmitters in cerebral of poststroke depression (PSD)rats and to investigate the mechanism of pharmacotherapeutics on PSD. Methods Rats were divided randomly into the sham-operated group,the normal saline group,the low dose of vinpocetine group and the high dose of vinpocetine group. Giving the left middle cerebral artery occlusion, the PSD rat model was established by unexpected chronic mild stress. When the PSD rat model was established, vinpocetine group was given vinpocetine(5mg/kg, 10mg/kg) and the normal saline group was given normal saline. Then the ethological score of depression was evaluated on 14 and 28 days. The monoamine transmitter in the frontal cortex and hippocampus and brainstem were detected by the fluorospectrophotometry. Results On the 28th day after the model establishment,compared with the normal saline group, the ethological score of depression level was decreased obviously. Compared with the normal saline group, vinpocetine could improve the ethological score of depression level of the PSD rat model, and these concentrations of 5-hydoxytrypatarmine ( 5-HT), noradrenalin ( NE ) and dopamine ( DA ) in the frontal cortex, hippocampus and brainstem. The level of NE ( ( 192.4 ± 34.8 ) ng/g, ( 206. 0 ± 41.7 ) ng/g,(91.1 ±23.0) ng/g] ,5-HT( (494. 1 ± 50.7) ng/g, (599.7 ± 39.2) ng/g, (541.7 ± 62.6) ng/g) and DA ( ( 298.6 ± 32.6) ng/g, ( 297.0 ± 38.1 ) ng/g, ( 85.9 ± 24.3 ) ng/g) in the high dose of vinpocetine group were significantly higher than that in the normal saline group ( NE (92.4 ± 17.5 ) ng/g, ( 131.4 ± 34.8 ) ng/g, (49.0 ±13.6)ng/g;5-HT(367.8 ±87.3) ng/g,(498.7 ± 79.6) ng/g, (320.4 ±59.4) ng/g; DA( 106.1 ±23.0)ng/g,(97.0 ±21.7)ng/g, (50.4 ± 13.8 )ng/g)(P ＜ 0.01 ). There were increased obviously by the high dose than the low dose of vinpocetine group. Conclusion Vinpocetine could treat PSD by increasing the level of monoamine transmitters in PSD rats' brain.

ObjectiveTo observe the effect of vinpocetine sustained-release capsules on post-stroke depression and recovery of neurological function. MethodsA total of 64 patients with acute post-stroke depression were randomly divided into Vinpocetine sustained-release capsules group( 34 cases) and control group(30 cases). Conventional therapy was given to both groups. To the treatment group, vinpocetine sustained-release capsules was given at the same time. Depression status was assessed with Hamilton Rating Depression Scale(HAMD). Meanwhile ,Mimi-Mental State Examination( MMSE), National Institutes of Health Stroke Scale(NIHSS) and Activities of Daily Living(ADL)were given in to both groups. ResultsAfter 6 to 12 weeks' therapy, the total score of HAMD, NIHSS and ADL of Vinpoeetine group were significantly lower than the control group ( all P ＜ 0.05 ), MMSE score increased significantly ( P ＜ 0.05 ) in Vinpocetine group. The curative rate and effective rate of Vinpocetine group were 38％ and 91％. It was significantly higher than the 20％ and 73％ of the control group ( all P ＜ 0.05 ). ConclusionVinpocetine sustainedrelease capsules was effective to treat post-stroke depression. It could improve the emotional state of patients and promote the recovery of neurological function.

Objective To investigate the indications and efficacy of endovascular stenting for the treatment of thoracic aortic aneurysm.Methods From March 2005 to October 2008,21 patients with Stanford type B aortic dissection,5 cases of pseudoaneurysm,and 2 patient with intramural hematoma complicated with ulcer of the aortic wall were treated by endovascular stenting under general(2 cases) or local(26 cases) anesthesia in our hospital.Medtronic Talent stent was employed in 10 cases,Medtronic Valiant stent was used in 12,and microinvasive straight-type stent was used in 6 patients.Results The operation was completed successfully in all of the 28 cases.Angiography showed that the gaps in the aorta were closed without endoleak.No patient had chest pain or neurological complications.The patients were discharged in(4.5?1.1) days(range 3-7 days).Five patients developed fever after the operation and were cured by indomethacin in one month.One week after the surgery,in 21 cases,CT scan showed enlarged aortic dissection,improved blood supply,thrombus in the false lumen of the thoracic aorta,and a false lumen in the abdominal aorta.In the 5 cases with pseudoaneurysm,CT scan confirmed that the rupture was closed with thrombus being detected in the lumen.The aortic ulcers that were detected in the 2 cases,who had intramural hematoma,were covered by the stents.Of the patients,a follow-up of(21.3?10.2) months(range 1-40 months) was available in 23 patients,who had no complications during the period.Conclusions Endovascular stenting is a simple,safe and effective method for Stanford type B aortic dissection,pseudoaneurysm,and intramural hematoma,resulting in quick recovery,less complications,and short hospital stay.

OBJECTIVE:To establish a method for detecting bacterial endotoxins in methylthioninium chloride injection (MCI) quantitatively. METHODS: Kinetic turbidimetric limulus test was applied to detect bacterial endotoxins in MCI quantitatively, and compared with gel-clot method. RESULTS: MCI was un-interfered with the test for bacterial endotoxins at the concentration of 0.125 mg?mL-1; the content of bacterial endotoxins in all samples tested (10 mg?mL-1) were not more than 0.25 EU?mg -1, which were in accordance with the result of gel-clot method. CONCLUSIONS: Kinetic turbidimetric limulus test provides a new way to detect bacterial endotoxins in MCI quantitatively.

Objective To study the situation of pathogenic bacteria of neonate infection in hospital,so can guide clinical doctors use antibiotic rationally. Method The secretions of 159 neonates′ umbilous and eye matter orders were collected to be used as the specimen and the drug susceptibility experiment was done using MIC and K-B methods together in 159 neonates with hospital infection.Results One hundred and eighty-nine pathogenic bacterias were isolated from 1613 specimens.According to our materials,staphylococci aureus was the most important pathogenic bacteria,then staphylococci heamolyticus,staphylococci epidermidis,encherichia coli ,enterobater cloucac ,klebsiella pneumoniae.MRSA- positive rate was 52.6%,ESBLs-positive in E coli was 21%,inklebsiella pneumoniae was 20%.Drugs of sensitivity for Gram positive coccus were vancomycin(0) clindamycin(8.5%) cipnofloxacin(12.2%);the drugs of sensitivity for Gram negative ord were imipenem (4.4%),cipnofloxacin(5.3%),amikacin(12.7%).Conclusion It is instructive that use antibiotic rationally for controlling neonate infection in hospital.

AlM: To investigate the influences of 577nm panretinal photocoagulation ( PRP ) on the retinal thickness of macular fovea on diabetic retinopathy ( DR) .METHODS:A total of 45 eyes of 37 cases suffering from preproliferative diabetic retinopathy ( PPDR ) and proliferative diabetic retinopathy ( PDR ) undergoing 577nm PRP were enrolled in this study. The alterations of the retinal thickness of macular fovea measured by optovue optical coherence tomography( OCT) before and 1, 3, 6mo following PRP were comparatively analyzed.RESULTS: The macularfoveal retinal thickness after 1, 3mo of PRP had significantly increased that before operation (P<0. 05). After 6mo postoperative follow-up, it gradually recovered to the level before PRP, with no significant difference (P>0. 05).CONCLUSlON: After the treatment of PRP, it appeared a transient increase on the retinal thickness of macular fovea, but after 6mo following-up, the macular foveal retinal thickness decreased nearly to the levels before PRP.
