Objective To compare drug therapy in patients suffering from chronic heart failure between Tianjin and Kashi region of Xinjiang autonomous region and to analyse their disparities in drug uses by guideline between the two regions.Methods All data were retrospectively taken from the hospitalized chronic heart failure cases from June 2005 to June 2006 in the 2nd Hospital of Tianjin Medical University and the 2nd People's Hospital of Kashi in Xinjiang respectively.The heart functions level NYHA Ⅱ-Ⅳ were recorded for analysis of drug use in the two regions.Results 749 cases were enrolled,491 from Tinajin and 258 from Kashi of Xinjiang.The average age of group Tianjin[(70.39±10.84)yrs]was older than that[(62.91±12.54)yrs]of group Kashi(t=8.488,P＜0.01).The distribution of≥165 cases in the group Tianjin(75.6%)was higher than that of group Kashi(51.2%)(X2=45.642,P＜0.01).The male cases in group Tianjinwere 264(53.8%)andthatwere 134(51.9%)in group Kashi with no significant differences in sex distribution between the two groups(P＞0.05).The first three etiological diseases were coronary heart disease(84.9%),rheumatic heart disease(5.9%)and dilated cardiomyopathy (3.3%)in group Tianjin,and that were coronary heart disease(63.2%),pulmonary heart disease(19.8%)and dilated eardiomyopathy(6.6%)in group Kashi respectively.The proportions of level NYHA Ⅱ,Ⅲ,Ⅳ on admission were 29.7%,39.1%and 31.2%in group Tianjin respectively,and that were 15.5%,39.5%and 45.0%in group Kashi respectively,with significant difference in heart function levels between the two groups(X2=22.770,P＜0.01).Theusages of nitrides and β-blockers in group Tianjin were more than that in group Kashi(both P＜0.01).The usages of diuretics,digitalis was more in group Kashi(all P＜0.01).There was no difference in ACEI usages between the two groups.The dosages of drugs in group Tianjin achieved the target dosages by the guideline and the dosages in group Kashi did not achieve the targets.The use frequency of β-blockers was more in male cases and＜65yrs respectively of group Tianjin.The usage frequency of uretics and aldosterone antagonist were more in＜65yrs cases of group Kashi and the usages of nitrides,ACEI,B-blockers,calcium antagonists,aldosterone antagonist of male cases were more than that of female cases(all P＜0.05)in this group.The usages of uretics,digitalis,aldostemne antagonist increased following the grading of heart function of the two groups(P＜0.05).Moreover the usage of ACEI decreased following the worsen heart function in group Tainjin and this was not the same in group Kashi.Conclusion There are differences in drug medications for chronic heart failure between Tianjin and Kashi.The majority of treatment drugs in Tianjin is approaching the guideline and there is a gap from guideline in Kashi of Xinjiang,especially on the dosage.

OBJECTIVE:To provide reference for the individualized treatment of opioid drugs by investigating the effects of OPRM1 A118G gene polymorphism on opioids dosage in Chinese Han Population patients with cancer pain. METHODS:66 Chi-nese Han Population patients with medium and severe cancer pain were selected from a third grade class A hospital. Using fluores-cence in-situ hybridization,OPRM1 A118G genotypes were detected to compare the opioids dosage of different genotype in pa-tients with cancer pain. RESULTS:Among 66 patients,distribution frequency of AA,AG and GG genotype were 36.36%, 53.03% and 10.61%,respectively;those of A and G allele were 62.88% and 37.12%;the daily dosage of opioids in AA,AG, GG genotype patients respectively were(21.67±13.41),(42.00±32.18)and(87.14±73.65)mg,with statistical significance(P<0.001). Among 39 patients receiving opioids for the first time,the dosage of 6 AA genotype patients and 15 AG genotype patients had been adjusted,with statistical significance(P=0.026). After adjusting dosage,daily dosage of AA genotype and AG genotype patients were (16.11 ± 9.16) and(28.57 ± 18.52)mg,with statistical significance (P=0.011). CONCLUSIONS:OPRM1 A118G genotype can influence the dosage of opioid in Chinese Han Population patients with cancer pain,and gene polymorphism can be used as evidence for dosage guide of opioids.

Objective To observe the role of brain-derived neurotrophic factor (BDNF) in the plasticity of enteric nervous-smooth muscle system,and to investigate the effects of BDNF induced plasticity on gastrointestinal motility in mice.Methods Male hybrid BDNF knockout (BDNF+/) mice and wild type (BDNF+/+) mice were selected,eight in each group.Gastrointestinal motility of BDNF+/+ mice and BDNF+/ mice were tested and compared.Longitudinal muscle strips of mice colon smooth muscle were prepared.The effects of carbachol (1 × 10 5 mol/L) and BDNF (1 × 10 7 mol/L) on contractile function of muscle strips were observed.And the effects of tetrodotoxin (TTX,1 × 10-6 mol/L) on BDNF induced contractile function of muscle strips were also studied.The changes of the density of mice intestinal myenteric plexus and the expression of smooth muscle α-actin (α-SMA) in colon smooth muscle were detected by immunohistochemical techniqne.The ultrastruetural alterations of myenteric plexus,neuromuscular junction (NMJ) and smooth muscle cells were detected by transmission electron microscope (TEM).T-test or Rank sum test was performed for comparison between groups.Results Number of feces particles and water content in feces of BDNF+/-mice ((3.80±0.75) and (39.60±1.47)％) were both lower than those of BDNF+/+ mice ((6.30± 1.03) and (51.00± 1.61) ％),and the differences were statistically significant (t=4.792,12.827;both P＜0.05).Carbachol (1 × 10-5 mol/L) could significantly increase contraction activity of smooth muscle of BDNF+/+ mice (R =3.26 ± 0.43) and BDNF+/-mice (R=2.15 ± 0.36),and the difference was statistically significant (t=15.754,9.632;both P＜0.05).The effects on contraction exciting of smooth muscle strips of BDNF+/+ mice were more significant than BDNF+/ mice,and the difference was statistically significant (t =5.972,P＜0.05).BDNF could significantly increase contraction of muscle strips of BDNF+/+ mice and R value increased from 1 to 1.41±0.09,and the differences were statistically significant (t=13.674,P＜0.05).TTX could obviously inhibit the excitatory effects of BDNF,R value decreased from 1.41 ± 0.09 to 1.03 ± 0.04 (t=11.692,P＜0.05).The density of myenteric plexus of BDNF+/ mice (median 5.8％,interquartile range 4.2％-7.0％) was significantly lower than that of BDNF+/+ mice (median 9.0％,interquartile range 7.1％-10.8％),and the difference was statistically significant (Z =3.730,P＜ 0.05).The expression of α-SMA of BDNF+/-mice (median 33.4％,interquartile range 28.8％-38.5％) was significantly lower than that of BDNF+/+ mice (median 44.6％,interquartile range 39.2％-48.8％),and the difference was statistically significant (Z=4.565,P＜0.05).The results of TEM indicated ultrastructural alterations of myenteric plexus,NMJ and smooth muscle in BDNF+/-mice.Conelusionss BDNF could induce the plasticity of morphology and function in enteric nervous-smooth muscle system,which may play an important role in mice gastrointestinal motility.

Hegu needling is mainly used for the treatment of orthopedic and neurologic diseases, such as cervical spondylosis, third lumbar transverse process syndrome, myofasciitis, periarthritis of shoulder, and stroke sequela, which has a rapid and benefial effect in relieving pain and improving symptoms and signs. It is often combined with other treatment methods, such as point-point needling, electric needling, QI needling, SHU needling, bloodletting, stagnant needling, warm needling, ginger partitioned moxibustion, Qistimulated massage, Tuina, bonesetting and xercise therapy. Filiform needle or round sharp needle are mostly used in Hegu needling. At present, the acupoints of Hegu needling are mostly Ashi points or stimulation points, but the acupoints of the fourteen meridians are rarely selected. Hegu needling is rarely used in the treatment of gynecological and pediatric diseases. Hegu needling has certain effect on dementia, vertigo, panic attack, trigeminal neuralgia, facial paralysis, and cancer pain, but few clinical studies confirmedit.

This paper is aimed to study the feasibility of myocardial infarction risk assessment by noninvasive multivariable trend analysis, including heart rate variability (HRV), deceleration capacity (DC) of heart rate and pulse wave velocity (PWV). Thirty five patients with cardiovascular diseases (11 Myocardial infarction (MI), 8 coronary artery disease (CAD), 6 artery atherosclerosis (AA) and 10 hypertension), and 31 healthy subjects were randomly selected into a control group for this research as comparison. 15 min ECG and 1 min pulse wave data were collected based on the analysis workbench developed by our Lab. HRV, DC and PWV between the cardiovascular group and the control group were analyzed and compared. The results showed that the HRV indices, DC and PWV were significantly higher than those in the control group. The DC and the HRV indices including NN50, PNN50 and TINN especially presented a decline trend that was consistent with the regularity of cardiovascular development process. This noninvasive multivariable trend analysis of HRV, DC and PWV can be a reference for the earlier risk prediction of MI.
