Objective To investigate the relationship between transfusion transmitted virus (TTV)infection and neonatal hyperbilirubinemia,the effect of TTV infection on the liver function, and analyse the feature of nucleotide sequences in TTV ORF1.Methods Serum TTV DNA,which were from 58 neonates with high direct bilirubin(DB,including 5 with hepatitis Syndrome),92 ones with high indirect bilirubin(IB),and 85 normal ones,was detected using a nested polymerase chain reaction technique(nPCR),electropherosis and sequence analyse,and serum alanine amniotransferase (ALT)was determined in all neonates.Results In DB neonates,TTV DNA were detected in 7 neo- nates(12.1%,including 3 neonates with hepatitis syndrome);in IB and normal ones,1 neonate had positive TTV DNA(1.1% and 1.25),respectively.Even if there were point mutations in Guangdong's TTV,the homology of Guangdong's TTV(GD1-9)and Japanese TTV(N22)ranged from 87.1%～97.8% at nucleotide level.Conclusion TTV infection may be one of important pathogenesis resulting in neonatal hyperbilirubinemia and liver damage in such patients.Guangdong's and Japanese TTV isolates had the same genotype,some gene mutations maybe increase the pathogenicity in TTV.

Tissues and organs generate angiogenesis under the stimulation of angiogenic factors in physiological or pathological conditions.Multiple signal pathways including VEGF, Notch, Wnt/β-catenin, Ang1(2)/tie2 and PIK-Akt etc.have effects on various stages of angiogenesis.VEGF exerts irreplaceable effects on the whole process of angiogenesis through multiple signal pathways.Over the past few years, new progress has been made in the researches of mechanisms regulating angiogenesis through VEGF-related signal pathways both at home and abroad.These findings provide us new theoretical basis for clarification of the pathogenesis of many diseases and clinical drug development.In this article we will summarize the recent research progress in this field, hoping to provide new possibilities for the treatment of angiogenesis-related diseases.

Objective To investigate the effect of intracoronary application of tirofiban on coronary slow flow patients with acute myocardial infarction during primary percutaneous coronary intervention (PPC1).Method It was a retrospective analysis of 187 patients with acute myocardial infarction treated with PPCI in the emergency department of Beijing Anzhen Hospital enrolled in this study from January,2008 through January,2011.The patients divided into 2 groups in terms of intra-coronary administration of tirofiban (tirofiban group) and intra-coronary use of nitroglycerol (control group).Data were statistically analyzed by using SPSS 13.0 software.Categorical variables were analyzed using x2 test and continuous variables were compared by t test.Results Between two groups,there were no differences in preoperative systolic pressure (P =0.245),the rate of TIMI flow 3 (P =0.568) after PPCI and ST segment resolution (P =0.824),LVEF (P =0.275) and in-hospital mortality (P =0.502).Compared with tirofiban group,the systolic pressure was lower and the rate of using intra-aortic counter-pulsation was higher in control group.Although the incidence of slight bleeding in the control group was lower than that in the tirofiban group,no severe bleeding was observed in both groups.Conclusions The effect of intracoronary use of tirofiban was similar to that of nitroglycerol in terms of improving slow flow of coronary artery.It could safely and effectively reduce the incidence of the coronary slow flow in the patients after PPCI,but it produced a little impact on systolic pressure.It may be a better method of choice for AMI patient with low blood pressure.

Objective To observe the effect of microprismatic needle scalpel(MPNS) on headache induced by compression of greater occipital nerve or lesser occipital nerve.Methods 95 patients with headache induced by compression of occipital nerve were divided into the treatment group (50 cases, treated with MPNS) and control group (45 cases, treated with carbamazepine).Results In the treatment group, 42 cases were cured, 6 cases were effective, 2 cases were ineffective; while, those in the control group were 16 cases, 21 cases and 8 cases respectively. There was a significant difference between two groups ( P<0.01).Conclusion MPNS has an obvious effect on headache induced by compression of occipital nerves.

OBJECTIVETo observe the impacts on the muscle strength in the patients of stroke-induced acroparalysis treated with Xunjingcuiqi needling technique.

METHODSOne hundred patients were randomized into a Xunjingcuiqi group and a routine acupuncture group, 50 cases in each group. In the routine acupuncture group, the routine acupuncture technique was adopted at the main acupoints, such as Shangxing (GV 23), Baihui (GV 20), Dicang (ST 4), Quchi (LI 11), Huantiao (GB 30) and Zusanli (ST 36), etc. In Xunjingcuiqi group, on the basis of the routine acupuncture technique, Xunjingcuiqi needling technique (pricking technique was quickly applied with the filiform needle along the running course of meridian to promote the conduction of meridian qi) was added. For the patients being hard to feel the needling sensation and with the muscle strength of 0 to 1 degree, Dongzhencuiqi technique was supplemented at shu-stream points of yang meridians (after qi arrival, the needling manipulation with limb movement was given to promote the conduction of meridian qi). The treatment was given once every day in the two groups. Ten treatments made one session. Three sessions of treatment were required. At the end of each session treatment, the muscle strength and clinical efficacy were assessed.

RESULTSIn the 1st, 2nd and 3rd sessions of treatment, 20, 24 and 36 cases achieved the 3 to 5 degrees muscle strength in Xunjingcuiqi group, respectively; and 6, 10 and 15 cases achieved the 3 to 5 degrees muscle strength in the routine acupuncture group. The differences were significant statistically in comparison of the two groups (P < 0.01, P < 0.05). The markably effective rates were 60.0% (30/50), 64.0% (32/50) and 70.0% (35/50) after the 1st, 2nd and 3rd sessions of treatment in Xunjingcuiqi group, respectively; and those were 38.0% (19/50), 44.0% (22/50) and 46.0% (23/50) in the routine acupuncture group, respectively. The differences were significant in the 1st and 3rd sessions of treatment between the two groups (both P < 0.05).

CONCLUSIONXunjingcuiqi needling technique combined with routine acupuncture achieves the apparent superior efficacy on acroparalysis induced by ischemic stroke as compared with the simple routine acupuncture. Xunjingcuiqi needling technique obviously improves muscle strength and shortens the duration of sickness.

OBJECTIVETo explore the correlation of the gene polymorphisms of Toll-like receptor 2 ( TLR2) and TLR4 with the susceptibility and recurrence of condyloma acuminatum (CA).

METHODSUsing Snapshot, we detected the gene polymorphisms of TLR2 597(T/C), 1350(T/C), 15607(A/G), and 2258(G/A) and TLR4 896(A/G) and 1196(C/T) in the peripheral blood of 140 CA patients and 105 HPV-negative controls. We made comparisons between the CA patients and controls as well as between the cases of recurrent CA and those of non-recurrence at 6 months after treatment.

RESULTSThere were 72, 48, and 20 cases of genotype TT, TC, and CC of TLR2 597 (T/C), respectively, in the CA patients, as compared with 71, 31, and 3 cases in the controls. The gene frequency of mutant C was 31. 43% in the patients, significantly higher than 17.62% in the controls (χ2 = 12.04, P < 0.01), and it was 38.68% in the recurrent cases, remarkably higher than 27.01% in the non-recurrent cases (χ2 = 4.16, P < 0.05). There were 74, 49, and 17 cases of genotype TT, TC, and CC of TLR2 1350( T/C), respectively, in the CA patients, as compared with 73, 29, and 3 cases in the controls. The gene frequency of mutant C was 29. 64% in the patients, significantly higher than 16. 67% in the controls (χ2 =11.05, P < 0.01), and it was 36.79% in the recurrent cases, markedly higher than 25. 29% in the non-recurrent cases (χ2 = 4.18, P < 0.05). There were 44, 66, and 30 cases of genotype AA, AG, and GG of TLR2 15607(A/G), respectively, in the CA patients, as compared with 26, 58, and 21 cases in the controls. There was no significant difference in the gene frequencies of mutant G between the two groups (χ2 = 0.33, P > 0.05). No mutant genes of TLR2 2508 (G/A) or TLR4 896(A/G) and 1196(C/ T) were detected in either the CA patients or the controls. Linkage disequilibrium analysis showed a tight linkage between TLR2 597 (T/C) and 1350(T/C) (D' = 1, r2 = 0.93).

CONCLUSIONTLR2 597(T/C) is tightly linked to 1350(T/C), which is correlated with both the susceptibility and the recurrence of condyloma acuminatum.
