Migraine is a complex and heterogeneous disorder. Although several genetic models has been proposed including autosomal-dominant/autosomal recessive, sex-linked, sex-limited, mitochondrial, and multi-gene, none of these models can well-explain the transmission of the disease. We hypothesied that migraine is a sex-conditioned inherited disorder (autosomal dominant in females and autosomal recessive in males). This hypothesis is supported by the evidence such as the locations of genes associated with familial hemiplegic migraine, possibly "typical" migraine as well (dominantly on chromosome 19p, 1q, and 2q), male:female ratio of prevalence (1:2-1:4), the mostly youth-onset, the provocation by the contraceptives, the induction by menstruation, and the self-limitation after menopause. Female sex-hormones appear to be the key contributor to a higher prevalence of migraine in female. Socio-environmental factors may also play an important role.

OBJECTIVETo determine serum carnitine levels in patients with liver diseases and to investigate their significance.
METHODS25 patients with acute viral hepatitis, 34 with chronic viral hepatitis, 22 with post hepatitis cirrhosis with normal renal function, 9 with post hepatitis cirrhosis but with renal disfunction, and 40 healthy subjects (serving as controls) were enrolled in this study. An enzymatic cycling method was used to determine the serum free carnitine levels.
RESULTSThe serum free carnitine level was (48.3+/-10.2)micromol/L in the healthy control group. It was (35.2+/-13.2)micromol/L in the acute viral hepatitis group, (36.5+/-9.9)micromol/L in the chronic viral hepatitis group, (45.0+/-11.0)micromol/L in the post hepatitis cirrhosis with normal renal function group, and (83.6+/-50.4)micromol/L in the post hepatitis cirrhosis with renal dysfunction group. Serum free carnitine levels in the acute viral hepatitis and chronic viral hepatitis groups were significantly lower than those in the healthy controls. There were no significant differences in serum free carnitine levels of the post hepatitis cirrhosis group and the normal control group.
CONCLUSIONSPatients with liver diseases can have carnitine metabolism errors. One of the secondary carnitine lack causes is liver disease.

To investigate the mechanisms underlying the cholinergic agonist carbachol-induced cardiovascular responses, changes of renin-angiotensin system were examined in fetal hormonal systems. In the ovine fetal model under stressless condition, the cardiovascular function was recorded. Blood samples were collected before (during baseline period) and after the intravenous administration of carbachol. Simultaneously, the levels of angiotensin I (Ang I), angiotensin II (Ang II) and vasopressin in the fetal plasma were detected by immunoradiological method. Also, blood gas, plasma osmolality and electrolyte concentrations were analyzed in blood samples. Results showed that in chronically prepared ovine fetus, intravenous infusion of carbachol led to a significant decrease of heart rate (P < 0.05), and a transient decrease followed by an increase of blood pressure (P < 0.05) within 30 min. After the intravenous infusion of carbachol, blood concentrations of Ang I and Ang II in near-term ovine fetus were both significantly increased (P < 0.05); however, blood concentration of vasopressin, values of blood gas, electrolytes and plasma osmolality in near-term ovine fetus were not significantly changed (P > 0.05). Blood levels of Ang I and Ang II in the atropine (M receptor antagonist) + carbachol intravenous administration group was lower than those in the carbachol group without atropine administration (P < 0.05). In conclusion, this study indicates that the near-term changes of cardiovascular system induced by intravenous administration of carbachol in ovine fetus, such as blood pressure and heart rate, are associated with the changes of hormones of circulatory renin-angiotensin system.

[To explore the effect of Humifuse Euphorbia Herb ( HEH) on alleviating insulin resistance in type 2 diabetic KK-Ay mice. Totally 40 KK-Ay mice fed with high-fat diet were divided into four groups: the metformin group, the model group, the HEH low-dose group and the HEH high-dose group, and orally administrated with metformin hydrochloride (250 mg x kg(-1)), distilled water, humifuse euphorbia herb 1 g x kg(-1) and 2 g x kg(-1). Besides, C57BL/6J mice with ordinary feed were taken as the normal control group and orally administrated with equal distilled water. The oral administration for the five groups lasted for eight weeks. Before and after the experiment, weight, fasting glucose and insulin tolerance were determined. The morphological changes in pancreas were observed through hematoxylin-eosin (HE) staining on pancreatic tissue sections. The serum insulin, TNF-α, IL-6, adiponectin (ADPN) and leptin (LEP) were detected by ELISA. The results showed that HEH could reduce weight and fasting glucose in KK-Ay mice, alleviate hyperinsulinemia, reduce blood glucose-time AUC, increase 30-min blood glucose decline rate, relieve insulin resistance, significantly ameliorate the pathomorphological changes in pancreas in each group, decrease serum TNF-α, IL-6 and leptin levels in KK-Ay mice and rise serum ADPN level. This study proved that humifuse euphorbia herb can ameliorate the insulin resistance in KK-Ay mice, and its mechanism may be related to the effect on inflammatory factors and adipocytokines.

OBJECTIVEThe purpose of this article is to examine the effect of curcumin on the proliferation and metastasis of human tongue squamous cell carcinoma and analyze its mechanism.
METHODSSCC-4 were treated with curcumin of 0, 5, 10, 20, 30, 60, 100 micromol x L(-1) in 24 h. MTT assay, Matrigel invasion assay, flow cytometry and fluorescence microscopy were used to examine the effect of curcumin on the growth and metastasis of SCC-4. cDNA microarray and RT-PCR were employed to analyze the expression of genes treated by curcumin.
RESULTSThe results showed that curcumin could concentration-dependently inhibit SCC-4 cell proliferation at the concentration range from 20 to 100 micromol x L(-1). Furthermore, Matrigel invasion assay indicated that curcumin can reduce SCC-4 cell invasion under the dosage of 20, 30, 60 micromol x L(-1). Flow cytometry also showed that curcumin can influence the distribution of cell cycle of SCC-4 cell with the dosage of 20, 30, 60 micromol x L(-1). And the dosage of 30 micromol x L(-1) curcumin could lead to the recruitment of alpha-tubulin. cDNA microarray showed that 87 genes were activated and 198 genes were inhibited with the effect of curcumin. These results were validated by the real time quantitative RT-PCR.
CONCLUSIONAccording to the results, it suggests that curcumin has the potential as the leading compound for anti-cancer proliferation and invasion in oral cancer treatment, and cdc27, EGFR substrate 15, PPAR-alpha and H2A histone may play an important role among this multiple anticancer-targeting ability.

Objective To investigate the potential of neural stem cells (NSCs) injected into the cistema magna to migrate into the injured brain tissue to survive and differentiate into neural cells in rats with traumatic brain injury (TBI). Methods Embryonic NSCs cultured in vitro were labeled with BrdU and identified using immunofluorescence assay for nestin and BrdU expression. The labeled NSCs were stereotactically injected into the subarachnoid spaces of rats 24 h after experimental traumatic brain injury. The motor neurological function of the rats was assessed 24 h before and 24 h and 1 and 2 weeks after the injury, and immunohistochemistry was used to detect the expressions of BrdU, MAP2 and GFAP in the brain tissues. Results Positive expressions of nestin and BrdU were detected on the neurospheres by immunofluorescence assay. NSC transplantation resulted in significantly improved motor neurological function of the rats with traumatic brain injury (P<0.05). Immtmohistochemistry demonstrated the presence of BrdU-positive NSCs, MAP2-positive neurons and GFAP-positive glial cells in the traumatic brain tissue of rats 1 and 2 weeks after NSC transplantation. Conclusion Neural stem cells injected via the subarachnoid space can migrate into the injured rat brain tissue and differentiate into neural cells to promote the recovery of motor neurological function of rats with traumatic brain injury.
