Objective To evaluate the expression of Sp3 gene of peripheral blood mononuclear cells (PBMC) in multiple sclerosis (MS) patients in Guizhou and the relationship between Sp3 gene expression and immunological function. Methods Two pairs of primers were used to amplify cDNAs generated from 31 MS patients and 30 healthy controls. The serum levels of sIL-2R were measured in 27 patients with MS and 30 healthy controls by sandwiched ELISA. Results The deficient expression of Sp3 gene in MS patients was significantly higher than that in control (41.9% ( 12/31 ) vs 6. 7% (2/30) ,x2 =7. 133 ,P =0. 008). The sIL-2R levels in MS patients were significantly higher than those in control (( 2788.5 ± 1079. 8 ), ( 1270. 7 ± 489. 4) μg/L, t = 6. 170, P = 0. 001 ). The concentration of sIL-2R in MS with negative ((3364.0 ± 1252.3) μg/L) and positive((2450.0 ± 827.0) μg/L) expression of Sp3 gene were significantly increased compared with control (F = 32. 059, P < 0. 05 ). The sIL-2R levels were significantly rising in MS patients with negative expression of Sp3 gene compared with MS patients with positive expression of Sp3 gene ( q = 4. 213, P < 0. 05 ). Conclusions A remarkable deficient expression of Sp3 gene in PBMC has been found in MS patients in Guizhou. sIL-2R may take part in the process of MS. The expression of Sp3 gene is not affected by immune state, however, MS patients with Sp3 deficient expression tend to have a more serious impairment in immunological functions.

OBJECTIVE: To establish an HPLC method for the determination of the contents of the related substances in metoclopramide.METHODS: The sample was separated on C18 column with the mobile phase consisted of acetonitrile-0.02 mol?L-1 phosphonic acid solution(19∶81) at a flow rate of 1.0 mL?min-1.The detection wavelength was set at 275 nm;the column temperature was kept under room temperature and the injected volume was 20 ?L.The contents of the related substances in metoclopramide were computed by self-control method of main constituent.RESULTS: Under the above described chromatographic conditions,metoclopramide was completely separated from its impurities.A good linearity between impurities' peak area and metoclopramide(contrast solution) concentration was achieved when the concentrations of impurities were over the range of 0.05%～4.0%.The lowest detectable limit of metoclopramide was 0.3 ng,and the contents of the related substances were all less than 0.26%.CONCLUSION: The method is convenient,accurate,sensitive and,specific,and it can be used for the determination of the related substances in metoclopramide.

OBJECTIVETo observe the effect of Bushen Wenyang Huayu Recipe (BWHR) on hypoxia inducible factor-1α (HIF-1α), proline hydroxylase2 (PHD2), von Hippel Lindau disease (VHL) suppressor gene expressions in endometriosis (EM) rats with Shen yang deficiency blood stasis syndrome (SYDBSS), and to explore the pathogenesis of EM and the mechanism of BWHR for treating EM.

METHODSTotally 50 SD rats were randomly divided into five groups, i.e., the blank control group, the sham-operation group, the model group, the Chinese medicine (CM) group, and the Western medicine (WM) group, 10 in each group. Rats in the blank control group and the sham-operation group were fed routinely. Rats in the rest 3 groups received 30-day "extended refrigerator freezing and ice water immersion" and combined with " autotransplantation" to establish EM rat model with SYDBSS. One Milliliter BWHR at 3.33 g/mL was administered to rats in the CM group by gastrogavage. Gestrinone at the daily dose of 0. 5 mg/kg was administered to rats in the WM group by gastrogavage. Equal volume of normal saline was administered to rats in the model group, the blank control group, and the sham-operation group. The size and morphology of ectopic foci in rats were observed after 4 weeks of medication. Expressions of serum CA125, plasma cyclic adenosine monophosphate (cAMP), and plasma cyclic guanosine monophosphate (cGMP) were detected by radioimmunoassay. Morphological changes of eutopic endometrium and ectopic tissue were observed under the optical microscope by HE staining. Protein expressions and contents of HIF-lα, PHD2, and VHL were detected by immunohistochemical SABC method and Western blot. mRNA expressions of HIF-1α, PHD2, and VHL were detected by RT-PCR.

RESULTSThe ectopic foci grew significantly in the model group. Their volumes were obviously contracted after treated by CM and WM. Compared with the blank control group and the sham-operation group, serum CA125 and plasma cGMP obviously increased, cAMP obviously decreased (P < 0.05); expressions and contents of HIF-1α mRNA and protein all decreased (P < 0.05); mRNA and protein expressions and contents of PHD2 and VHL all decreased in the model group (P < 0.05). Compared with model group, levels of CA125 and cGMP obviously decreased; cAMP levels obviously increased, expressions and contents of HIF-1α mRNA and protein all increased, mRNA and protein expressions and contents of PHD2 and VHL all increased in the WM group and the CM group (P < 0.05). Compared with the CM group, PHD2 protein contents were higher in the WM group (P < 0.05). HIF-1α was negatively correlated with PHD2 (r = -0.799, P = 0.00). HIF-1α was negatively correlated with VHL (r = -0. 625, P = 0.003).

CONCLUSIONSBWHR could effectively treat EM. Its mechanism might be associated with reducing contents of HIF-1α, serum CA125, and plasma cGMP, and up-regulating expressions of PHD2, VHL, and cAMP.

OBJECTIVETo explore the neuropsychological characteristics of children with attention deficit hyperactivity disorder (ADHD).

METHODSNeuropsychological tests, including visual working memory, Stroop test, digits inverse reciting, vocabulary fluency, Wisconsin card sort test (WCST), and Temporal discounting were used to evaluate the capacity of response inhibition, phonological working memory, visual working memory executive function and delayed satisfying capacity of subjects.

RESULTS1. The ADHD children spent longer time [ADHD-I (84(20), ADHD-C: 98 (31), normal: 70 (28)] to accomplish color naming and made more errors [ADHD-I: 3 (3), ADHD-C: 6 (19), normal: 2 (5)] than the normal control when the color was inconsistent with the word meaning in Stroop test (P < 0.01). 2. The scores of digits reciting [ADHD-I: 3 (3), ADHD-C: 3 (4), normal 4 (4)] inverse was lower in ADHD than in normal control (P < 0.01). 3. The representation of ADHD was poorer than normal control in visual working memory [ADHD-I: 21 (3), ADHD-C: 20 (5), Normal: 20 (3)], and in delayed visual memory [ADHD-I: 19 (5), ADHD-C: 19 (5), Normal: 20 (5)] (P < 0.01). 4. The scores of vocabulary fluency [ADHD-I: 1 (1), ADHD-C: 2 (1), normal: 0 (0)] was lower in ADHD than in normal control (P < 0.01). 5. In WCST, the ADHD children made more errors [ADHD-I :15 (17), ADHD-C: 15 (15), normal: 13 (13)] and less classification [ADHD-I: 5 (4), ADHD-C: 5 (4), normal: 5 (3)] than normal control (P < 0.01). 6. In Temporal discounting, the ADHD children showed significantly more impairments than normal control did (P < 0.01). 7. There was significant difference between the two subtype groups on some tests (P < 0.01).

CONCLUSIONSObvious cognitive impairments were found in children with ADHD, involving poor response inhibition, impaired working memory, dysfunction of planning and set-shifting, and there was no significant difference between the two subtype groups.
