Objective To observe the therapeutic efficacy of eight nape needle therapy in treating mild cognitive impairment (MCI) after cerebral stroke. Method By following a randomized controlled trial design, 200 eligible patients were randomized into an eight nape needle group and a medication group by the random number table, with 100 cases in each group. The patients all received basic medications, while the eight nape needle group was additionally intervened by acupuncture at the eight nape acupoints including Fengchi (GB20), Fengfu (GV16), Dazhui (GV14) and Xiangsihua points (Extra), and the medication group additionally received oral administration of nimodipine. The intervention lasted eight weeks, followed by a three-month follow-up. Before and after treatment, the two groups of patients were evaluated by Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA) and Barthel Index (BI). Result Respectively at four-week and eight-week treatment and the follow-up, the scores of MMSE, MoCA and BI showed improvements compared with the corresponding baseline (P<0.01, P<0.05);compared with the medication group, the eight nape needle group was superior to the medication group comparing the MMSE score at each time point after treatment (P<0.01, P<0.05); there were no significant differences in the MoCA and BI scores between the two groups at four-week treatment (P>0.05), but the differences were significant at eight-week treatment and the follow-up (P<0.01). Conclusion Eight nape needle therapy can effectively improve the cognitive function in patients with MCI after cerebral stroke.

Objective: To investigate the effects of herbal cake-partitioned moxibustion on the plasma levels of trimethylamine (TMA), trimethylamine-N-oxide (TMAO), and flavin-containing monooxygenase 3 (FMO3) in rabbits with atherosclerosis (AS), as well as to explore the possible mechanism of herbal cake-partitioned moxibustion in treating AS. Methods: After 1-week adaptive feeding, 28 male New Zealand rabbits were divided into a blank group, a model group, an antibiotic group, and a herbal cake-partitioned moxibustion group according to the random number table method, with 7 rabbits in each group. Rabbits were fed with a basic diet in the blank group, while with a basic diet plus 1％ choline in the remaining groups to prepare the AS model. Rabbits were given drinking water with broad-spectrum antibiotics in the antibiotic group, and herbal cake-partitioned moxibustion in the herbal cake-partitioned moxibustion group for 12 weeks. The atherosclerotic plaques by hematoxylin-eosin (HE) staining, the blood lipid levels, the plasma TMA and TMAO levels by liquid chromatography-mass spectrometry were detected for rabbits in each group at the end of interventions. Liver FMO3 protein expression was detected by Western blotting. Liver FMO3 mRNA expression was detected by real-time fluorescence quantitative polymerase chain reaction. Results: HE staining showed that the arterial wall was rough, the intima was significantly thickened, and more foam cells and lipid deposits were seen in rabbits of the model group. Arterial wall thickening was not obvious with a few foam cells and lipid deposits in the herbal cake-partitioned moxibustion group. Compared with the blank group, the serum levels of low-density lipoprotein cholesterol (LDL-C) and total cholesterol (TC) were increased (P<0.01), the plasma levels of TMA and TMAO were increased (P<0.05, P<0.01), and the expression levels of liver FMO3 protein and mRNA were all increased (P<0.05, P<0.01); while the serum high-density lipoprotein cholesterol (HDL-C) level was decreased in the model group (P<0.05). Compared with the model group, the LDL-C and TC levels were decreased (P<0.01 or P<0.05), the HDL-C levels were increased (P<0.01), the TMA and TMAO levels were decreased (P<0.05), while the protein and mRNA expression levels of FMO3 were decreased without statistical significance in the herbal cake-partitioned moxibustion group and the antibiotic group. Conclusion: Herbal cake-partitioned moxibustion can slow atherosclerotic plaque formation and regulate lipid levels in AS rabbits, and the mechanism may be related to the down-regulation of TMA and TMAO expression in the plasma.

OBJECTIVE: To study the interactive regulatory effect of histone acetylation and methylation on cardiomyogenesis, and to provide a theoretical basis for the prevention and treatment of congenital heart disease. METHODS: A total of 24 Kunming mice were randomly divided into embryo day 14.5 (ED 14.5) group, embryo day 16.5 (ED 16.5) group, postnatal day 0.5 (PND 0.5) group, and postnatal day 7 (PND 7) group, with 6 mice in each group, and the heart tissue of fetal and neonatal mice was collected. Colorimetry was used to measure the activities of histone acetylases (HATs) and histone methyltransferases (HMTs) in the myocardium. Western blot was used to measure the expression of H3K9ac and H3K9me3 in the myocardium. RESULTS: Colorimetry showed that the activities of HATs and HMTs were higher before birth and were lower after birth. There was a significant difference in the activity of HATs in the myocardium between the PND 0.5 and PND 7 groups and the ED 14.5 group (P<0.05), as well as between the PND 7 group and the ED 16.5 group (P<0.05). There was also a significant difference in the activity of HMTs in the myocardium between the PND 7 group and the ED 14.5 and ED 16.5 groups (P<0.05). Western blot showed higher expression of H3K9ac and H3K9me3 before birth and lower expression of H3K9ac and H3K9me3 after birth, and there were significant differences in the expression H3K9ac and H3K9me3 in the myocardium between the PND 0.5 and PND 7 groups and the ED 14.5 and ED 16.5 groups (P<0.05). CONCLUSIONS The dynamic expression of HATs, HMTs, H3K9ac, and H3K9me3 is observed during cardiomyogenesis, suggesting that histone H3K9ac acetylation and histone H3K9me3 methylation mediated by HATs and HMTs may play a role in interactive regulation during cardiomyogenesis.

Objective To study the effect of ulinastatin on no reflow or slow flow in the infarct related artery in patient with acute ST-elevation myocardial infarction (STEMI) undergoing emergency percutaneous coronary interventional therapy (PCI).Methods 180 STEMI patients were divided into the control group (n=100) and the ulinastatin treatment group (n=80).The control group received conventional PCI treatment and the treatment group received conventional PCI treatment plus ulinastatin. The level of serum inflammatory factors IL-6,IL-10,superoxide converting enzyme,the infarct related coronary artery reperfusion TIMI flow grade (TFG) and myocardial perfusion grade (TMPG),the results of postoperative cardiac ultrasound examination and clinical outcomes were compared between the two groups.Results Compared with the control group,the level of IL-6 was decreased,while the levels of IL-10 and superoxide converting enzyme were increased significantly in the ulinastatin treatment group(P<0.05).The TFG and TMPG of the infarct related vessels were increased significantly in the ulinastatin treatment group. The left ventricular end diastolic diameter[(54.6 ± 5.2 mm vs. (50.4±4.6) mm,P=0.046)]and left ventricular ejection fraction [(58.4±10.2) % vs. (62.2±9.8) % P=0.048] showed statistical difference between the two groups.Compared to the control,the major cardiovascular event rate of the treatment group during hospitalization (1% vs. 5%, P=0.038), after one month (1.2% vs. 3%,P=0.046) and 6 months (3% vs 12%,P=0.018) were all significantly lower .There was no significant difference in mortality between the 2 groups.Conclusion Ulinastatin may lower the incidence of no flow and slow flow after emergency PCI,improve heart function and the lower the rates of MACE.

OBJECTIVESTo explore the clinical features of traumatic atlantoaxial instability combined with subaxial cervical spinal cord injury (CSCI), and to analyze the feasibility, indication and therapeutic effects of anterior-posterior approach in such cases.

METHODSFrom March 2004 to September 2009, 16 cases with this trauma were admitted and surgically treated in our department. Before surgery, skull traction was performed. Posterior atlantoaxial pedicle screw internal fixation and bone graft fusion were conducted to manage traumatic atlantoaxial instability. As for subaxial CSCI, anterior cervical corpectomy or discectomy decompression, bone grafting and internal fixation with steel plates were applied.

RESULTSAll operations were successful. The average operation time was 3 hours and operative blood loss 400 ml. Satisfactory reduction of both the upper and lower cervical spine and complete decompression were achieved. All patients were followed up for 12 to 36 months. Their clinical symptoms were improved by various levels. The Japanese Orthopaedic Association (JOA) scores ranged from 10 to 16 one year postoperatively, 13.95+/-2.06 on average(improvement rate equal to 70.10%). X-rays, spiral CT and MRI confirmed normal cervical alignments, complete decompression and fine implants'position. There was no breakage or loosening of screws, nor exodus of titanium mesh or implanted bone blocks. The grafted bone achieved fusion 3-6 months postoperatively and no atlantoaxial instability was observed.

CONCLUSIONSTraumatic atlantoaxial instability may combine with subaxial CSCI, misdiagnosis of which should be especially alerted and avoided. For severe cases, one stage anterior-posterior approach to decompress the upper and lower cervical spine, together with reposition, bone grafting and fusion, as well as internal fixation can immediately restore the normal alignments and stability of the cervical spine and effectively improve the spinal nervous function, thus being an ideal approach.

OBJECTIVETo investigate the relationships between rs3865418 polymorphism of neural precursor cell expressed developmentally downregulated 4-like gene and obesity in Kazakh general population.

METHODSBased on a cross-sectional epidemiological study in a Kazakh general population, a case-control study was conducted. The rs3865418 polymorphism in a Kazakh general population (856 subjects, including 364 males and 492 females; 478 in obesity group and 378 in normal control group) was genotyped by TaqMan polymerase chain reaction, and the relationship between rs3865418 polymorphism and obesity was analyzed.

RESULTSThe rs3865418 polymorphism was successfully genotyped in 851 Kazakh subjects. The distribution of the genotypes and alleles of rs3865418 polymorphism did not differ significantly between the obesity group and normal control group in terms of general populations, males, and females (all P > 0.05). The waist circumference showed a tendency of C/C > C/T > T/T in males and C/C < C/T < T/T in females, but without statistical significance (P > 0.05).

CONCLUSIONSThe rs3865418 polymorphism of neural precursor cell expressed developmentally downregulated 4-like gene may not be associated with obesity in Kazakh general population. In other words, it is not a predisposing factor for obesity in Kazakh.

The inhibition activity of 36 flavonoids against CYP1A2 was determined by our previously developed in vitro method. The Comparative Molecular Similarity Indexes Analysis (CoMSJA) approach was used to probe the quantitative relationships between the flavonoids' molecular structural descriptors and their inhibitory activities. A reliable CoMSIA model with the combined electrostatic and hydrophobic fields was derived with the regression coefficient R2 of 0.948 and the cross-validation regression coefficient q2 of 0.630, separately, which is capable of elucidating the quantitative relationship between the 3D structural descriptors of the flavones and their bioactivities. Comparing with flavone, the larger pi-pi conjugated system of alpha-naphthoflavone significantly improved the biologically inhibitory ability. Based on the core structure of the latter, either electropositive substituents or hydrophobic groups at the 6, 3', and 4' ring positions or electronegative counterparts at the 5 ring position, can enhance the inhibitory potency against CYP1 A2 according to the CoMSIA contour maps.
