Purpose: In order to explore the clinical effect in acupuncture treatment of vascular headache. Methods: 93 cases of vascular headache were randomly auocated into acupuncture group (n= 30), treated by puncturing Fengchi (GB 20), Ashi point and Sanyinjiao (SP 6) on the sick side, acupuncture plus needle-embedding group (n= 36), treated by basic acupuncture treatment plus needle-embedding method in Taiyang (Ex-HN 5) and Xuanzhong (GB 39) on the sick side, and control group (n = 27), treated with oral administration of 5 mg Sibelium,twice a day, for observation of the changes in the clinical symptoms before and after treatments in the patients of three groups. Results: After treatment, the clinical symptoms in the patients of three groups were relieved or disappeared. The recent therapeutic effect was better in acupuncture plus needle-embedding group than in the control group (P＜ 0.05), and there was no significant difference (P＞ 0.05) between the acupuncture plus needle-embedding group and acupuncture group and there was no significant difference (P ＞ 0.05) between acupuncture group and control group, either. The long-term therapeutic effect was better in the acupuncture plus needle-embedding group than in the control group (P＜ 0.01), in the acupuncture group than in the control group (P ＜ 0.05), and there was no significant difference between the acupuncture plus needle-embedding group and acupuncture group. Conclusion: Acupuncture treatment of vascular headache offers a better recent and long-term therapeutic effect, and acupuncture plus needle-embedding method is much better in the therapeutic effect.

Objective To investigate the clinical features of moyamoya disease complicated with Graves′disease and the efficacy of extra-and intra-cranial revascularization. Methods The clinical data of 4 patients with moyamoya disease complicated with Graves′disease were analyzed retrospectively. Among them,three were females and one was a male. Their mean age was 32 ± 7 years. After medical treatment, their thyroid function was normal. The patients were treated with superficial temporal artery-middle cerebral artery bypass grafting. Results (1) Three patients showed cerebral infarction and one showed frequent transient ischemic attack. DSA confirmed that 2 patients had unilateral moyamoya disease and 2 had bilateral moyamoya disease. Head MRI revealed brain infarcts. (2) The thyroid function was normal after drug treat-ment,the symptoms of moyamoya disease were stable in 3 cases. One patient had high metabolic symptoms, such as high fever and accelerated heart rate within one week after procedure. The patients were followedup for 6 to 18 months,one was good,3 were excellent,and there was no recurrence of Graves′disease. Postoperative head MRI revealed that the 4 patients did not have new brain infarcts. MRA showed that the arterial filling in cerebral sulci in the ischemic lesion areas was obviously improved compared with that before procedure. Retrograde filling of the ipsilateral middle cerebral artery M2-M3 segment was observed in 2 patients. Postoperative single photon emission computed tomography perfusion imaging revealed that the ischemic perfusion lesions on the operated sides were obviously improved compared with those before procedure. Conclusion When complicated with Graves′ disease,the symptoms of moyamoya disease will aggravate. It manifests as acute and chronic cerebral ischemia. After controlling the symptoms of hyperthyroidism,most cerebral ischemic symptoms can be alleviated. Superficial temporal artery-middle cerebral artery bypass grafting may establish an effective collateral circulation and improve the clinical symptoms.

As a heritable regulation , epigenetics can regulate gene expression by other ways without changing the DNA sequence ,and change cell or individual phenotypes .DNA methylation is an issue in the field of epigenetics research.Recently,many studies have been demonstrated that the methylation of repetitive DNA ,spe-cific gene and CpG island and loss of imprinting play an important role in tumor occurrence .As the development of technological approaches to DNA methylation ,we have a more comprehensive understanding on methylation pat-terns.As specific markers,abnormal methylation sites in the genome can be used in the diagnosis ,treatment and prognosis predictor of disease .For tumor development caused by DNA methylation ,the application of demethylat-ing drugs have achieved good effect in clinical treatment .

Indoleamine 2,3-dioxygenase 1 (IDO1) is the rate-limiting enzyme in the degradation of tryptophan to kynurenine. IDO1 is highly expressed in some tumor tissues. IDO1 can deplete tryptophan in tumor microenvironment, inhibit T cell function, and mediate the immune escape of tumor cells. Thus, IDO1 is considered a potential target of tumor immunotherapy. Currently, there are several IDO1 inhibitors in clinical research studies. The mechanism of IDO1-mediated tumor immune escape and the structure of IDO1 inhibitors are summarized in this review.

A chiral LC-MS/MS method for the simultaneous analysis of desvenlafaxine (DVS) enantiomers in human plasma was developed and applied to a pharmacokinetic study on 12 Chinese healthy volunteers. d6-Desvenlafaxine was used as internal standard (IS). Chromatographic separation was performed on the Astec Chirobiotic V chiral column (150 mm x 4.6 mm, 5 μm). The assay was linear over the concentration range of 0.500-150 ng x mL(-1) for both enantiomers (r2 > 0.99). The method was successfully applied to a stereoselective pharmacokinetic study of 100 mg desvenlafaxine sustained release tablets on 12 Chinese healthy volunteers under fasting conditions. The results showed that the pharmacokinetic parameters were similar to both enantiomers in Chinese healthy volunteers. The AUC(0-t), and C(max) of the two enantiomers were about 1.5 times higher than those of blacks and whites reported in the literature.

OBJECTIVETo explore the effect of drug-containing serum of Chinese herbal compounds [Xiongshao Capsule (XS, for activating blood) and Huanglian Capsule (HL, for dispelling toxin)] on tumor necrosis factor-alpha (TNF-alpha)-induced adherence between human umbilical vein endothelial cells (HUVECs) and polymorphonuclear neutrophils (PMN), inflammatory reaction and expression of related proteins in mitogen-activated protein kinase (MAPK) pathway.

METHODSThirty-two rats were randomly divided into four groups (8 in each group) using random digit table: the blank control group treated with distilled water, the test group I treated with Chinese herbal compound of XS (0.135 g/kg), the test group II treated with Chinese herbal compound of HL (0.135 g/kg), and the test group Ill treated with Chinese herbal compound of XS (0.135 g/kg) and HL (0.135 g/kg). All medication was given by gastrogavage once a day for a week. Rats' blood serum was harvested 1 h after the last administration to prepare drug-containing serum. HUVECs were exposed to TNF-alpha (100 ng/mL) to induce cell injury model and incubated with corresponding drug-containing serum (10%) for 24 h. Normal rats' serum was given to cells in the blank control group and the model group, while XC + HL containing serum was given to cells in the rest 3 groups. The adherence of HUVECs and PMN cells was detected by using rose bengal strain. Levels of E-selectin, intercellular adhesion molecule-1 (ICAM-1), and interleukin-1beta (IL-1P) in the supernatant of cultured HU-VECs were determined by ELISA. Protein expressions of mitogen-activated protein kinases p38 (p38MAPK) and extracellular signal-regulated kinase 1/2 (ERK 12) were determined by Western blot.

RESULTSCompared with the blank control group, HUVECs were seriously injured; PMN adherence amount significantly increased; levels of E-selectin, ICAM-1, and IL-1beta increased; expression levels of p-p38MAPK and p-ERK 1/2 in the supernatant of HUVECs significantly increased in the model group (all P < 0.01). Compared with the model group, HUVECs-PMN adherence amount decreased (P < 0.05); levels of E-selectin, ICAM-1, and IL-1 beta in the supernatant of HUVECs decreased (P < 0.01, P < 0.05); expression levels of p-p38MAPK and p-ERK 1/2 of endothelial cells decreased in the test group I, II, and III (P < 0.01).

CONCLUSIONSDrug-containing serums of activating blood, activating blood and dispelling toxin could attenuate TNF-alpha induced injury of HUVECs, inhibit HUVECs-PMN adherence and the release of adhesion factors. Its mechanism might be involved with protein phosphorylation of p38MAPK and ERK 1/2 in the MAPK pathway.

OBJECTIVETo evaluate the effects of Shenfu Injection (SF) on cytokines during cardiopulmonary bypass (CPB) in infants.

METHODSTwenty-four infants with congenital heart disease, aged below three years, were randomly assigned to the control group and the SF group equally. In the SF group, 1 mL/kg of SF was given through center vein pump after center vein puncture being performed, while only normal saline was given instead in the control group. Blood sample was obtained for measurement of serum necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) concentration by ELISA, at various time points in the process, i.e. right after anesthesia induction (T1), beginning of CPB (T2), aortic off-clamping (T3), 20 min after CPB (T4), the end of CPB (T5), and 6 h (T6) and 24 h (T7) after CPB.

RESULTSThe time for reverting to sinus heart rhythm and analepsia after CPB was shorter in the SF group than in the control group (P < 0.05). Serum concentration of TNF-a and IL-6 was equal in the two groups at T1; they increased significantly after CPB (P < 0.05), reached the peak value at T4 and reduced to the normal level at T7 in the control group. TNF-alpha concentration was significantly lower at T3, T4 and T5, and IL-6 concentration was lower at T4 in the SF group than that in the control group at corresponding time point (P < 0.05).

CONCLUSIONSF could shorten the time for reverting to sinus heart rhythm and analepsia after CPB in infants, and suppress the inflammatory response caused by CPB.
