OBJECTIVE: To compare the therapeutic effect of Changchun'an sustained-release capsules and Nimodipine tablets on the treatment of vascular cognitive impairment.METHODS: A total of 120 patients with vascular cognitive impairment were randomly divided into treatment group and control group, with 60 patients for each group. Patients In the treatment group were treated with Changchun'an sustained-release capsules, 30 mg for each administration, twice a day; the other patients in the control group were treated with Nimodipine tablets,30 mg for each administration, 3 times a day. The treatment course was 6 months for both groups. The scores of clinical efficiency,Mini-Mental State Examination (MMSE), and Activity of Daily Living Scale (ADL) were analyzed.RESULTS: The total effective rates of Changchun'an sustained-release capsules and Nimodipine tablets were 60.0% and 53.3%,respectively, and there was significant difference in the total effective rates between treatment and control groups (P < 0.05). The scores of MMSE and ADL in both groups were improved obviously after treatment compared with before treatment (P < 0.01),and there was a significant difference between the two groups after treatment (P < 0.05). The side effects of Changchun'an sustained-release capsules were obviously posterior to those of Nimodipine tablets.CONCLUSION: Changchun'an sustained-release capsules are effective in treating vascular cognitive impairment with few side effects.

Objective To observe the effects of fluoride of different dose on the proliferation of the cultured human umbilical vein endothelial cells(HUVEC). Methods The cells were treated with NaF at different doses. Cell counting, MTT colorimetry, flow cytometry (FCM) and immunohistochemistry were used to detect the endothelial cells activities. Results Compared with the fluoride free control, the positive rate of PCNA and Ki-67 were higher as NaF concentration was at 120-240 ?mol/L and were highest at 240 ?mol/L, the same was seen in the values of A and PI, as NaF concentration was at 600-960 ?mol/L,these indexes decreased. Conclusion In vitro, the low concentration of fluoride can promote the proliferative activity of HUVEC, whereas the high concentration can inhibit it.

Objective To study the characteristics of its pathologic and neurophysiologic changes of a ani-mal model of cervical spinal cord compression, and to explore the relationship between the severity of spinal cord inju-ry and its functions. Methods Thirty-two rabbits were divided into 4 groups randomly. A catheter was inserted intothe vertebral canal and a balloon was inflated to compress spinal cord in epidural space. According to the diameter ofballoon, the animals were divided into 4 groups (A, B, C, D group), Each group consisted of 8 rabbits. The corti-cal somatosensory evoked potential (CSEP) and motor evoked potential (MEP) were used to assess neurologicalfunction. Motor function behavior was scored before and on 1, 3, 7 and 14 days after surgery. Histological observa-tions were performed, pathological changes were observed by light and electron microscope. Results Spinal cordcompression resulted in a gradual increase of the peak latency and significant decrease of the peak amplitude. The la-tency and amplitude of MEP were changed more dramatically than those of CSEP. The result indicated that MEP wasmore sensitive than CSEP to the compression. Analysis also revealed that the severer the pathologic changes, the lon-ger the latency and the lower the amplitude of the evoked potentials. Conclusion The animal model presented inthis paper was simple and standardized. Evoked potentials as a noninvasive technique have great value in monitoringspinal cord function. The variance of amplitude and the latency in significantly correlate with the degree of compres-sion of the spinal cord.

Objective To evaluate the value of low-density lipoprotein-cholesterol (LDL-C) and non-high-density lipoprotein-cholesterol (non-HDL-C) in differential diagnosis of familial hypertriglyceridemia (FHTG) and familial combined hyperlipidemia (FCHL).Methods We recruited 9 FHTG pedigrees (94 subjects) and 24 FCHL pedigrees (94 subjects) and then divided them into affected groups and non-affected groups according to lipid abnormality.Another 10 normal control pedigrees (57 subjects) served as controls.We compared the routine lipid levels such as triglyceride (TAG),total cholesterol (TC),HDL-C and LDL-C and non-HDL-C between the groups.After stratification based on TAG level,we observed the relationship between LDL-C and non-HDL-C.Last we confirmed and analyzed the cut-off value of differential diagnosis between FHTG and FCHL with receiver operating characteristic (ROC) curve.Results The levels of TAG,TC,and non-HDL-C were significantly higher in the affected group of FHTG than in the non-affected group of FHTG and the normal group (P＜0.01 or P＜0.05).The levels of TAG,TC,HDL-C,LDL-C and non-tHDL-C wcrc significantly higher in the affected group of FCHL than in the non-affected group of FCHL and the normal group (P＜0.01 or P＜0.05).The levels of TAG were significantly higher (P＜0.01) while TC,HDL-C,LDL-C and non-HDL-C levels were significantly lower (P＜ 0.01 or P＜0.05) in the affected group of FHTG than in the affected group of FCHL.The association between LDL-C and non-HDL-C was positive both in FHTG and FCHL,but the relationship became weaker as TAG level increased.The cut-off value of LDL-C and non-HDL-C was 3.575 mmol/L and 4.525 mmol/L,respectively.Conclusion In addition to the routinely used lipid indexes,non-HDL-C may be a new index for differential diagnosis of FHTG and FCHL,and may be superior to LDL-C in this regard.
