The basic physiological function of anti-arrhythmic drugs is affects myocardial cell membrane ion channels. Change the ion flow and affect cell electrophysiological properties, change the conduction velocity, eliminate retrace, inhibit autorhythmicity and trigger events, inhibit the occurrence of arrhythmia, but will trigger a new activities, new retrace, produce new arrhythmia. In recent years, with the improvement of the theoretical system of traditional Chinese medicine and the production of new research methods, Chinese medicine treatment of arrhythmia has a new development. This article summarized the recent decades of which Chinese medicine monomer anti-arrhythmic drugs that had been proved by the influence of monomer anti-arrhythmic drugs, lists the differents traditional Chinese medicinal materials which chemical composition and the effective of the anti-arrhythmic effects, shows the unique advantages of Chinese medicine in the aspect of anti-arrhythmic, and points out that the current Chinese medicine in anti-arrhythmic (monomer) existing problems and solutions.

And the clinical effect were measured by AOFAS Ankle Hind-foot Scale System. Results The 24 patients were followed up for 26 months averagely (12~36 months). According to AOFAS Ankle Hind-foot Scale System, there were 4 cases of mod-erate and 20 cases of bad before treatment, and there were 18 cases of excellent, 4 cases of good, and 2 cases of moderate after the treat-ment. Conclusion It can achieve good clinical results in treatment of necrosis of talus through triple arthrodesis and bone grafting combined with plat screw internal fixation.

Objective To investigate the influence of epigallocatechin gallate ( EGCG)on reactive oxygen species (ROS) in mouse podocytes exposed to high glucose. Methods Mouse podocytes cultured in high glucose were exposed to different concentrations of EGCG (0.2, 10, 100 μmol/L) or α-tocopherol (0.2 μmol/L) for 6, 12, 24 hours. The viability of podocytes was detected by MTT. The intracellular formation of ROS was detected by confocal microscopy with fluorescent probe CM-H2DCFDA and was measured by fluorescence microscopy. RT-PCR was used to examine the expression of p22phox, p47phox and p67phox mRNA in cultured podocytes exposed to different concentrations of EGCG. Results Intracellular ROS generation was significantly higher in high glucose than that in control conditions (P<0.01). EGCG could significantly inhibit ROS induced by high glucose significantly (P<0.01). EGCG (100 μmol/L) led to an inhibition of the increased production of NADPH oxidase components of p22phox and p67phox mRNA in high glucose (P<0.05). The expression of p47phox mRNA in high glucose was inhibited by EGCG(0.2 μmol/L) and ot-tocopherol(0.2 μmol/L) (P<0.05). Conclusion EGCG can protect cultured mouse podocytes from injury of high glucose by inhibiting ROS formation.

OBJECTIVETo study the effect of electro-acupuncture (EA) at Neiguan (PC6) and Lieque (LU7) on the expression of protein kinases in cardiomyocytes of myocardial ischemia (MI) rats.

METHODSHealthy male SD rats were randomly divided into the control group, the model group, the Neiguan point group, the Lieque point group, and the non-meridian non-acupoint group, 10 in each group by random digit table. The MI rat model was established by injecting isoprenaline hydrochloride (85 mg/kg). EA at Neiguan (PC6), Lieque (LU7), and non-meridian non-acupoint were respectively performed. Changes of the expression of protein kinases [such as protein kinase A (PKA), protein kinase C (PKC), protein kinase G (PKG)] in rat cardiomyocytes were observed using Western blot.

RESULTSCompared with the control group, expression levels of PKA, PKC, and PKG increased obviously in the model group (P < 0.01). Compared with the model group, expression levels of PKA, PKC, and PKG decreased in the Neiguan point group and the Lieque point group (P < 0.01, P < 0.05). Expression levels of PKA decreased in the non-meridian non-acupoint group (P < 0.01). Compared with the Neiguan point group, expression levels of PKA, PKC, and PKG increased in the non-meridian non-acupoint group and the Lieque point group (P < 0.01, P < 0.05). Compared with the Lieque point group, expression levels of PKA, PKC, and PKG increased in the non-meridian non-acupoint group (P < 0.01, P < 0.05).

CONCLUSIONEA at Neiguan (PC6) and Lieque (LU7) could decrease protein expression levels of PKA, PKC and PKG in rat myocardial cells, and the effect of acupuncture at Neiguan (PC6) was better than that obtained by EA at Lieque (LU7).

Objective To investigate clinical result of hepatectomy and porta-enterostomy in the treatment of Bismuth type Ⅳ hilar cholangiocarcinoma.Methods Nine patients with Bismuth type Ⅳ hilar cholangiocarcinoma underwent accurate hilar resection(portal parecnchyma resection including about Ⅰ cm of the hilar part of the segments 5 and 4b and caudate lobe beyond the tumor),and the biliary drainage was reconstructed by Roux-en-Y portal parecnchyma-jejunum lpop anastomosis.None of the biliary radicals had to be ligated and all of them were drained into thus constructed"biliary pool".Results Hilar resection was successfully performed in all cases,and there was no postoperative mortality.Aspartate transaminase and alanine transaminase and serum bilirubin decreased evidently four weeks later.Three patients presented postoperative complications.One patient developed a transient anastomotic leakage,while one patient developed self-limiting hemobilia,wound infection occurred in one patient.All three patients were treated conservatively and recovered.The mean Karnofsky performance score was 86,with which they could carry on normal activity with minor symptoms of disease.Two patient died after 9 months and 17 months of extensive metastasis and intrahepatic metastasis respectively.The remaining seven patients are alive by a mean followup of 24.9 months after surgery without any signs of recurrence.Conclusions With accurate hilar resection and portal parecnchyma-to-enterostomy,the patients considerably benefit from the preservation of liver parenchyma and patent biliary drainage and radical resection.So the Hew technique prolongs the survival time and enhances the quality of life of the patients.

Objective To investigate the expression of granulocyte-macrophage colony-stimulating factor (GM-CSF) and its associated mechanism during the wound healing. Methods The animal model with the full-thickness skin injury was used in the study. Fifty male mice were involved in the study and divided randomly into control group (n = 25) and GM-CSF group (n = 25). Each group had five time points (5 mice per time point). All the mice received full-thickness skin defect (1 cm × 1 cm) through the panniculus camosus on the midline of the back near the neck after anesthesia. Recombinant human granulocyte-macrophage colony stimulating factor (RhGM-CSF) gel (10 μg/cm2) were applied in the GM-CSF group and gel matrix without RhGM-CSF applied in the control group. The wound healing time and rate were observed at days 3, 5, 7, 10 and 14 after injury. The wound specimens were collected to detect the histopathological change. The microvessel density of the wound was counted based on the results of CD31 immunohistochemistry. RT-PCR was employed to detect the expression changes of GMCSF, platelet-derived growth factor (PDGF) , vascular endothelial growth factor ( VEGF) and stromal cell derived factor-1 (SDF-1). Results RT-PCR results showed that the gene expression of GM-CSF reached the peak at day 3 after injury (P＜0. 01) and kept the high level at days 3-10 after injury (P＜ 0. 05) , followed by a sharp decrease to a normal level at day 14 after wound. The wound healing time was average (2.4 ±0. 3) days earlier than the control mice after application of rhGM-CSF, with significant increase of the wound healing rate during 7-14 days after injury ( P ＜ 0. 05 ). In the GM-CSF group, the early histology of trauma wound showed a small number of neutrophils, obvious epithelial cell proliferation in the wound margin, marked hyperplasia of the granulation tissue, high cell density with quantity of spindle-shaped and oval-shaped cells and increased number of new blood vessels. The microvessel density was also increased significantly (P ＜ 0. 05) at days 7-14 after injury. The gene expressions of VEGF and SDF-1 were significantly increased at day 7 and day 10 respectively after injury (P＜0.05) and the gene expression of pro-healing factor PDGF was significantly increased in every time point (at days 5, 7 and 10,P＜0.05;at day 14,P＜0.01). Conclusion GM-CSF expresses highly in the early stage after injury and can promote the wound healing, when the mechanism may relate to the up-regulated expressions of pro-angiogenic factors and pro-healing growth factors.

Currently available monotherapies of oral nucleoside/nucleotide analogs or interferon are unable to achieve a sustained and effective response in most of patients with chronic hepatitis B (CHB). The objective of the present study was to compare the efficacy and safety of pegylated interferon (Peg-IFN) alpha-2b plus adefovir dipivoxil combination therapy versus Peg-IFN alpha-2b alone. Sixty-one HBeAg-positive chronic hepatitis B patients were randomized to receive Peg-IFN alpha-2b alone (1.5 μg/kg once weekly) or Peg-IFN alpha-2b plus adefovir (10 mg daily) for up to 52 weeks. Efficacy and safety analyses were performed on all participants who received at least one dose of study medication. The rate of HBeAg seroconversion and undetectable HBV-DNA were evaluated after 52 weeks of therapy. At the end of treatment, 11 of 30 (36.7%) patients receiving combination therapy achieved HBeAg seroconversion versus 8 of 31 (25.8%) in the monotherapy group (P=0.36). In contrast, the percentage of patients with undetectable serum HBV DNA was significantly higher in the combination group than in the monotherapy group (76.7% vs. 29.0%, P<0.001). Thyroid dysfunction was more frequent in the combination group than in the monotherapy group (P<0.05). In HBeAg-positive CHB, combination of Peg-IFN alpha-2b and adefovir for 52 weeks resulted, at the end of treatment, in a higher virological response but without significant impact on the rate of HBeAg seroconversion and possibly an adverse effect on thyroid function.

Objective To separate and amplify Hantaan virus(HV)in serum of hemorrhagic fever patients with renal syndrome(HFRS)in Heilongjiang,and look for its difference from intemational standard type strain(76-118strains).Methods HVs of different phase in the 8erum of 50 HFRS patients were separated and amplified by RTnested-PCR,its products were analyzed the amplified by sequencing.Results Detectable rate of HV in the patients serum was 36.36%(8/22)in 7 days after onset,it Was 13.04%(3/23)in patients having an onset 8 days to 14 days earlier,5 cases were not detectable 15 days after onset.Comparing the sequence of HV S gene fragment,sample 1,9,18,31,37,38,44 strain had a homology of 90.24%,86.72%,89.97%,89.16%,86.45%,87.26%and 89.43%to 76-118 strains,respectively.Conclusions The positive rate is the highset in 7 days after onset.Nucleotide sequence difference exists between pathogenic strain of Heilongjiang's HV and international standard strain,indicating that not only hosts but also locations can affect HV.
