Acupuncture anesthesia is a technique by partially or completely replacing anesthetics with acupuncture in surgery based on the traditional acupuncture analgesia mechanism.It emerged in the 1950s,went viral in the 1970s and then gradually fell into decline.In the recent years,this technique has regained attention and further research.Acupuncture anesthesia can be classified as either pure acupuncture anesthesia or acupuncture-medication combined anesthesia.To expand the application of this technique,a patient with non-ST elevation acute coronary syndrome in urgent need of percutaneous coronary intervention (PCI) received pure acupuncture anesthesia because of an allergy to lidocaine,and the operation went successfully.This is the first time that pure acupuncture anesthesia and coronary arteriography were combined,which is of great significance in further study and development of acupuncture anesthesia.

Ulcerative colitis (UC) is a chronic inflammatory disease and its involvement area in colon is influenced by a complex network of gene interactions.We analyzed the weighted gene co-expression networks in microarray dataset from colonic mucosa of patients with UC and identified one gene co-expression module that was highly associated with the progression of involved area in UC colon (Pearson coefficient=0.81,P＜0.0001).In total,523 hub genes in this module were found to be involved in immune system process after enrichment analysis in Gene Ontology.By the STRING and Cytoscape analysis,we observed that interleukin-8 (IL-8) and matrix metalloproteinase-9 (MMP-9) were centered in the network of hub genes.We then detected the expression of IL-8 and MMP-9 in mucosa from left-sided colon of patients using quantitative PCR and immunofluorescence assay respectively.Both quantitative PCR and immunofluorescence assay revealed the expression levels of IL-8 and MMP-9 were significantly different among the healthy controls,left-sided colitis group and pancolitis group (P＜0.05).IL-8 and MMP-9 were detected with an enhanced expression in pancolitis as compared with left-sided colitis and healthy controls,respectively (P＜0.05).This study demonstrates that immune system process is indispensable in the progression of disease in colon,and identifies that IL-8 and MMP-9 play potential critical roles for the progression.

Objective To study the relationship between plasma creatinine and lactic acid levels in type 2 diabetic patients with normal renal function, and the effect of mefformiu administration on plasma lactic acid. Methods Blood samples were collected from 723 type 2 diabetic inpatients(275 cases treated with mefformin as treatment group and 448 without mefformin as control group). Plasma lactic acid was measured with enzyme-electrode assay. The fasting plasma glucose, fasting insulin, creatinine (Cr) , alanine aminotransferase (ALT), and HbA1C levels were also determined. Results (1) The lactic acid level in treatment group was significantly higher than that in control group [(1.33±0.57 vs 1.17±0.47) mmol/L, P<0.01] and so was the incidence of hyperlactacidemia (9.45% vs 4.91%, P<0.01). No lactic acidosis was found in all patients. (2) The correlation analysis showed that Cr, blood urea nitrogen, ALT and body mass index (BMI) were positively correlated with lactic acid in control group, and the positive correlation between Cr and lactic acid still existed (r= 0.345, P<0.01) after adjustment for ALT and BMI. (3) After being divided by 20 μmol/L Cr in control group, lactic acid levels in subgroup increased with the Cr levels, especially when Cr was over 90 μmol/L. The Cr cutpoint for predicting lactatemia was 95.35 μmol/L. Conclusion It is safe to administrate metformin in type 2 diabetic patients with normal renal function, along with low risk of lactic acidemia. The incidence of lactic acidemia may increase when plasma Cr level reaches 95.35 μmol/L,

To investigate the effects of carbamazepine (CBZ) on the plasma concentrations of valproic acid (VPA) and its toxic metabolite 2-propyl-4-pentenoic acid (4-ene VPA) in epileptic patients, the plasma concentrations of VPA and 4-ene VPA were determined, and the effect of CBZ on pharmacokinetics of VPA was evaluated. All patients had been divided into two groups (VPA group, n = 87; and VPA+CBZ group, n = 19). As compared to VPA group, the combination of CBZ significantly (P < 0.01) decreased the trough concentration of VPA [VPA group, (69.5 +/- 28.8) microg x mL(-1); VPA+CBZ group, (46.3 +/- 25.6) microg x mL(-1)] and does-adjusted VPA trough concentration [VPA group, (4.89 +/- 2.21) microg x mL(-1) x mg(-1) x kg(-1); VPA+CBZ group, (3.14 +/- 1.74) microg x mL(-1) x mg(-1) x kg(-1)]. However, the addition of CBZ did not influence the concentration of 4-ene VPA. The present study revealed that coadministration of CBZ can reduce VPA plasma concentration and may impact VPA clinical effect, therefore therapeutic drug mornitoring of VPA should be used when combined use of CBZ and VPA.

OBJECTIVETo compare the uptake of four contrast agents: (99)Tc(m)-RGD-4CK, (99)Tc(m)-N(NOET)(2), (99)Tc(m)-MIBI and (18)F-FDG in Bal B/c nude mice bearing human non-small cell lung cancer NCI-H358 and evaluate their diagnostic value in low-metabolic lung cancer.

METHODSHuman bronchioloalveolar carcinoma NCI-H358 cells were subcutaneously inoculated in Bal B/c nude mice to establish mouse models bearing human lung cancer. Twenty tumor-bearing nude mice were given injection of the four contrast agent, respectively, 5 mice in each group. SPECT imaging and biodistribution of the 4 tracers in the tumor-bearing nude mice were performed. The ratios of tumor to non-tumor (T/NT) of the tracers were compared.

RESULTSThe results from semi-quantification of the planar image and assessment of biodistribution showed that tumor to contralateral muscle activity ratios (T/NT) of the four tracers had statistically significant difference between each two of the four tracer groups of tumor-bearing mice (P < 0.001), with a highest value of T/NT ratio in the (99)Tc(m)-RGD-4CK group.

CONCLUSIONSNCI-H358 tumors show a higher uptake of (99)Tc(m)-RGD-4CK than (18)F-FDG. It suggests that when diagnosing a well-differentiated lung cancer such as bronchioloalveolar carcinoma, the contrast agent (99)Tc(m)-RGD-4CK may be more sensitive than (18)F-FDG, and it may become a promising contrast agent in tumor imaging diagnosis.

OBJECTIVETo investigate the biological effects of anti-beta(3) adrenoceptor (beta(3)-AR) autoantibody in the serum of patients with heart failure, which may contribute to a new therapeutic clue for heart failure.

METHODSThe synthetic peptide of the second extracellular loop of the beta(3)-AR was used as the antigen to screen sera of patients with heart failure and of healthy controls by using enzyme-linked immunosorbent assay. IgG in the patients group of positive autoantibody sera was prepared by using a MabTrap Kit (Amersham) following the manufacturer's instructions. The effects of IgG per each group both on contractile response of adult isolated cardiomyocytes and on beating frequency of cultured neonatal rat cardiomyocytes were observed.

RESULTSThe positive rate of anti-beta(3)-AR autoantibody was 26.7% (mean antibody titer: 1:43.27 +/- 2.71) or 11.0% (mean antibody titer: 1:14.59 +/- 1.61) in patients or healthy subjects, respectively P < 0.05. Compared with the control group, the autoantibody against beta(3)-AR from the patients group decreased cell shortening amplitude/cell shortening 3.84% +/- 0.33%, the velocity of shortening -0.47 microm/s +/- 0.07 microm/s and relengthening 0.17 microm/s +/- 0.02 microm/s in adult isolated cardiac myocytes, respectively. The autoantibody in the patients group decreased the beating rate in cultured neonatal rat cardiac myocytes by 47.1 beats/min +/- 8.11 beats/min, which could have a 6-hour continuance. This decreasing was not modified by Nadolol (beta(1)-AR and beta(2)-AR antagonist) in pretreating myocytes, but was nearly prevented by Bupranolol (nonselective beta-AR antagonist) or beta(3)-AR specific antigen.

CONCLUSIONIt seems reasonable to state that a high titer of the autoantibody against beta(3)-AR in the serum in patients with heart failure, which could have a negative inotropic and chronotropic effect, may be a part of pathophysiological mechanisms of heart failure.

0.05),while hyperlactacidemia existed in 21 patients(4.62%).LA levels increased with the creatinine levels,especially in those with Cr more than 90 ?mol/L.However,LA levels increased with the reduction of GFR,especially in those with GFR less than 80 mL/min.It was revealed by correlation analysis that LA level was positively correlated with Cr,ALT and BMI.The optimal cutoff of Cr inducing the lactic acidemia was 95.35 ?mol/L.Conclusion The baseline LA levels of patients with T2DM are similar to those of healthy adults,and LA levels are mainly influenced by BMI and renal and hepatic function.Hyperlactacidemia may be induced when Cr reaches a level more than 95 ?mol/L.

Aim To investigate the role of miR-125 b and its DNA methylation in homocysteine ( Hcy )-in-duced vascular smooth muscle cells( VSMCs) prolifera-tion. Methods VSMCs were stimulated with 0,50, 100, 200, 500 μmol · L-1 Hcy respectively. Then qRT-PCR was used to detect the mRNA levels of miR-125b,and nested-touchdown methylation-specific PCR ( ntMS-PCR) was used to detect the methylation levels of miR-125b. VSMCs were transfected with miR-125b precursor or the inhibitor of miR-125b ,then 3-(4,5-dimethylthiazol-2-yl)-2-5-diphenyl tetrazolium bromide ( MTT ) assay was used to reflect the proliferation of VSMCs. The distribution of CpG islands of miR-125b promoter region was analyzed by bioinformatics meth-ods. VSMCs were stimulated with 100 μmol·L-1 Hcy and transfected with or without DNA methylation inhib-itors 5-nitrogen impurity cytidine ( AZC) , then the ex-pression of miR-125b was detected by qRT-PCR. Re-sults The mRNA levels of miR-125 b were decreased in 100,200,500 μmol·L-1 Hcy group compared with 0 μmol·L-1 Hcy group. The precursor of miR-125b could inhibit the proliferation activity and the inhibitor of miR-125 b could increase the proliferation activity of VSMCs cells. Bioinformatics analysis indicated that MiR-125 b promoter region had a CpG island whose length was 792 bp ( 1881-2672 ) . The miR-125 b pro-moter region methylation levels increased after Hcy in-tervention ( P <0. 01 ) . The expression level of miR-125 b increased after AZC intervention ( P <0. 05 ) . Conclusions ① Hcy promotes vascular smooth mus-cle cell proliferation maybe by down-regulating the ex-pression of miR-125b. ② Hcy down-regulates the ex-pression of miR-125 maybe by up-regulating the methy-lation levels of miR-125b promoter region.
