OBJECTIVETo investigate the recipe-based pathogenesis and effects of Xiayuxue Decoction (XD), Yinchenhao Decoction (YcD), Yiguanjian Decoction (YgD) and Huangqi Decoction (HD) on carbon tetrachloride (CCl4) induced liver cirrhosis formation in rats on the basis of the recognition of basic pathogenesis of liver cirrhosis in TCM and train of thoughts of detecting the TCM syndrome by recipe.

METHODSModel rats of liver cirrhosis were established by subcutaneous injecting of 100% CCl4 3ml/kg followed by 50% CCl4 olive solution 2ml/kg, twice a week for 12 weeks. They were randomly divided into the model group, the XD treated group, the YcD treated group, the YgD treated group and the HD treated group. Rats in the three treated group received the treatment starting from the 9th week of modeling with the corresponding decoctions. All animals were sacrificed by the end of the 12th week, and their hepatic function, liver pathological changes and hydroxyproline (Hyp) content of hepatic tissue were detected.

RESULTS(1) Typical chronic liver injury and fibrosis became evident in the model rat at the 8th week and cirrhosis came into being at the 12th week. (2) Compared with the rats in the model group, hepatic pathological changes were alleviated significantly, content of Hyp in hepatic tissue was decreased markedly and hepatic function improved remarkably in the XD group and YgD group. The improvement in the XD group was superior to that in the YgD group, while the serum albumin level elevated more significant in the YgD group.

CONCLUSIONThe main pathological changes during CCl4 induced liver cirrhosis formation in rats is the rapid hyperplasia of hepatic fibrous connective tissue and obstruction of collaterals by blood stasis, thus induced reconstruction of the tissue structure, which could be treated with XD effectively, while the severe injury of liver parenchyma in this phase is another pathological change of Gan-yin deficiency syndrome, which could be effectively treated with YgD by its Yin-nourishing action.

OBJECTIVETo study the clinical effects of Reduning Injection on ordinary hand, foot and mouth disease (HFMD) in children.

METHODS76 children with confirmed diagnosis of HFMD were randomly assigned to 3 groups by the center randomization method, i.e., the Western medicine group (WM, 24 cases, treated with Ribavirin Injection or antibiotics), the Reduning Injection group (RI, 26 cases, treated with Reduning Injection), and the combination group (26 cases, treated with the combination of Reduning injection with Ribavirin Injection or antibiotics). The therapeutic course lasted for 3 to 7 days. A 3-day follow-up study was performed by the end of the treatment. The blood routines, the liver function, the renal function, the fasting blood glucose, the pyretolysis effect initiating time, the time for the body temperature recovery, and the rash subside time were observed in the three groups.

RESULTS(1) Of 76 patients, 13 dropped out, with the final effective case being 63. Of them, there were 19 cases in the WM group, 22 in the RI group, and 22 in the combination group. (2) Compared with the WM group, the pyretolysis effect initiating time and the time for the body temperature recovery were both significantly shortened in the RI group and the combination group (P<0.05, P<0.01). (3) There was no significant difference in the rash subside time among the three groups (P>0.05). But there was shortening tendency in the RI group and the combination group. (4) One child in the RI group dropped out from this study due to a mild rash, and no adverse drug reaction occurred in the other two groups.

CONCLUSIONSRI had some advantages in treatment of HFMD such as fasting pyretolysis effect initiating time, shorter time for the body temperature recovery, higher safety. Besides, it also could accelerate the subside of skin rashes to some extent.

OBJECTIVETo observe the therapeutic effect of Xiaozheng Rongmu Powder (XRP) for the treatment of progressive CCl4-induced liver cirrhosis in rats.

METHODSRat liver cirrhosis model was established by subcutaneous injection of 50% CCl4-olive oil 2 mL/kg twice a week for 12 weeks. Experimental rats were divided into the control group treated by saline and the two treatment groups, treated with XRP and Xiaochaihu Decoction, respectively, with the treatment starting from the 9th week of modeling. Rats were sacrificed at the terminal of experiment, the death rate, character of ascites, liver histological changes, liver function, mRNA expression of hepatocyte mitosis and the liver fibrosis associated markers in rats were observed.

RESULTSAt the end of the 8th week of modeling, serum levels of ALT, AST and TBil were increased, and Alb decreased significantly in rats (P < 0.01), cirrhosis formation with ascites could be seen in all rats. Meantime, levels of vascular smooth muscle alpha-actin, transforming growth factor-beta1, collagen I A2, tumor necrosis factor-alpha, tissue inhibitor of melalloproteinase-1 mRNA increased, while matrix melalloproteinase-13 mRNA were decreased significantly (P < 0.01), with visible liver proliferation to some extents. Further changes of above-mentioned abnormalities and clear suppression of hepatocytes mitosis were found in the modeled rats at the end of the 12th week. As compared to those occurred in the control group, changes in the XRP treated group were significantly milder at the corresponding duration, and clearly active hepatocytes mitosis was shown.

CONCLUSIONXRP, a Chinese drug with the effect of dissolving phlegm, removing stasis and supplementing qi, could reverse the progress of cirrhosis formation induced by CCl4, and it brings potential new hope for the treatment of advanced cirrhosis by Chinese medicine.

ObjectiveTo explore the effect of endovascular treatment for closed limb artery trauma. MethodsFrom March 2006 to December 2011,the clinical data of 12 cases treated for closed limb artery trauma were analyzed retrospectively.Catheters sheath were placed by antegrade or retrograde puncture.Catheters was send to the proximal end of the lesion.Intraoperatively through angiography the location and extent of arterial lesions were determined.Catheter with the help of guidewire were sent through the lesion to establish treatment “ pathway,at the lesion site suitable stents were placed to repair damaged arteries. ResultsThe procedure was all successful in 12 patients,there was no mortality nor sever compalications.Postoperatively 2 cases suffered from acute renal failure,and were managed and cured by continuous veno-venous hemofiltration (CWH).Osteofascial compartment incision decompression was carried out in 3 cases due to osteofascial compartment syndrome.One case of them suffered from amputation due to sever muscle necrosis and lost of limb function.Eleven patients were followed-up for 1year.All the arteries were patent.There were no stent break,deformation or stenosis.ConclusionsEndovascular techniques for the treatment of closed limb arterial trauma is safe and effective.

Objective: To observe the effect of electroacupuncture (EA) on serum interleukin (IL)-6, IL-8 and IL-10 in rat models of cerebral ischemia-reperfusion, and to discover the mechanism of EA in preventing and treating cerebral ischemia.
Methods:Male Sprague Dawley (SD) rats were randomized into a sham-operation (SO) group, a model control (MC) group, and an EA group, which were sub-grouped into a 6-hour group and a 24-hour group. In the SO group, rats only received vessel separation with filament placed inside without any treatment. In the MC and EA groups, the focal cerebral ischemia-reperfusion model was induced by using modified Longa method with intraluminal filament. The MC group didn’t receive any treatment;the EA group received EA at Baihui (GV 20) and Dazhui (GV 14) with sparse-dense wave for 30 min. The levels of serum IL-6, IL-8 and IL-10 were detected by using Elisa test.
Results: Six hours after ischemia-reperfusion injury, the levels of serum IL-6, IL-8 and IL-10 in the MC group were significantly higher than those in the SO group (P<0.01, P<0.05, P<0.05);the level of serum IL-8 in the EA group was significantly lower than that in the MC group (P<0.05), while there were no significant differences in comparing IL-6 and IL-10 between the EA group and the MC group. Twenty-four hours after ischemia-reperfusion injury, the levels of serum IL-6 and IL-8 in the EA group were significantly lower than those in the MC group (both P<0.05), while there were no significant differences in comparing the level of IL-10 among the three groups.
Conclusion:Early intervention by EA can regulate the levels of serum IL-6 and IL-8 in cerebral ischemic injury.

Objective To further investigated the effect of minocycline on the inhibition of microglial activation and subsequent protection of nigral DA neuron.Methods 20 rats injected with LPS in the substantia nigra (SN) were randomly divided into two groups (LPS group and LPS+Minocycline group).The behavior was observed on the 7~(th) d and 14~(th) d.The immunohistoehemistry,in situ hybridization and Western-blot were used to detect the levels of positive neuron,mRNA,protein of TH and OX-42. Results The slightly rotational behavior was observed in LPS+Minoeyeline group.The majority of mieroglias were activated in the two groups.Some microglia in the SNpc remained ramified in LPS+ Minocycline group.The numbers of hypertophie microglia in LPS+Minoeyeline group were less than that in LPS group.Western-blot showed that the protein of OX-42 in two LPS groups was higher than in normal group(P

OBJECTIVEAnalyze the clinical characteristics of the mild cases of pandemic influenza H1N1 virus infection, as well as the relationship of clinical characteristics and patient genders.

METHODSA total of 245 influenza A (H1N1) patients confirmed by viral nucleic acid detection were included in the study. The patients' personal information, signs and symptoms, lab and iconography data, disease course, negative seroconversion duration of new influenza A (H1N1) viral nucleic acid after antiviral treatment and hospitalization stay were analyzed. Measurement data were analyzed using one-way analysis of variance (ANOVA) by software SPSS 11.5. P < 0.05 was defined as statistically significant.

RESULTS(1) Among the 245 patients, 130 were males and 115 were females, yielding a sex ratio of 1.13:1. Almost 52.0% (127/245) of the patients came from Australia, and 64.5% (158/245) were between 18 and 40 years old. (2) Clinical manifestations included fever (98.4%, 241/245), cough (80.8%, 198/245) and throat congestion (95.9%, 235/245), and lab findings were characterized by elevated C-reaction protein (CRP, 71.0%, 174/245) and neutrophil (52.2%, 128/245). (3) Female patients had significantly lower serum Prealbumin (pre-A) levels than male patients [(245.04 ± 75.3) vs (273.34 ± 92.18) mg/L, F = 5.55, P = 0.019]. (4) The patients' serum CRF levels significantly decreased after the treatment [(4.06 ± 3.47) vs (14.54 ± 14.68) mg/L, F = 6.18, P = 0.016], while the levels of CD3, CD4 and CD8 were significantly increased after treatment [(1451.23 ± 443.97) vs (819.97 ± 375.75) cell/µl, F = 32.61, P = 0.000; (771.33 ± 251.92) vs (435.36 ± 215.35) cell/µl, F = 44.43, P = 0.000; (593.16 ± 237.19) vs (342.47 ± 180.12) cell/µl, F = 28.518, P = 0.000, respectively]. (5) Approximately 30.6% (75/245) of the patients had abnormal signs on chest CT iconography, and 22.0% (54/245) had obvious signs indicating pneumonia. The average disease course was (3.9 ± 1.2) days, the average hospitalization stay was (5.0 ± 1.4) days, and the negative seroconversion duration of the mRNA after antiviral treatment was (3.8 ± 1.4) days.

CONCLUSIONThe influenza A (H1N1) virus was characterized by fever, cough and throat congestion, with elevated CRP and neutrophil being the most significant lab findings. The influenza A (H1N1) strain was able to affect multiple organs, including being able to affect hepatic synthesis of pre-A as well as immune functioning. The influenza A (H1N1) influenza virus strain was mild clinically, with short disease course and good prognosis.

OBJECTIVETo detect the self-assembly morphology of sodium hyaluronate injection on mica using atomic force microscopy(AFM).

METHODSAtomic force microscopy with nanometer resolution was used to observe the self-assembly morphology of different concentrations of sodium hyaluronate injection on mica at room temperature.

RESULTSThe self-assembly morphology of 0.001, 0.01, and 0.1 mg/ml sodium hyaluronate injection on mica featured piebald, reticular and dendritic structures, respectively. At 1 and 5 mg/ml, sodium hyaluronate injection displayed bacilliform and spherical structures on mica, respectively; the diameter and height of the particles of 5 mg/ml sodium hyaluronate was 197.97±78.48 nm and 30.79±18.67 nm, significantly greater than those of 0.1 mg/ml sodium hyaluronate injection (49.52±11.93 nm and 5.37±1.59 nm, respectively, P<0.05).

CONCLUSIONThe self-assembly morphology of sodium hyaluronate injection on mica varies with its concentration. The piebald and reticular structure may facilitate the function of sodium hyaluronate, and the dendritic feature resembles the representative model of diffusion-limited aggregation (DLA).
