The contents of adenosine, gastrodin, 4-hydroxybenzyl alcohol, 4-hydroxybenzaldehyde, parishin and sulfur dioxide residue were compared in differently-processed Gastrodiae Rhizoma to provide the basis for a reasonable processing method of Gastrodiae Rhizoma. The analysis was performed on a Merck Purospher STAR column (4.6 mm x 250 mm, 5 μm) with a mobile phase consisting of methanol and water (containing 0.1% formic acid) under gradient elution at a flow rate of 1.0 mL x min(-1). The eluates were detected at 270 nm, and the column temperature was 35°C. The content of adenosin, gastrodin, 4-hydroxybenzyl alcohol, 4-hydroxy-benzaldehyde and parishin in processing of boiling or sulfur-fumigated were lower than that of in processing of steaming. Furthermore, the sulfur dioxide residue of sulphur-fumigated groups exceed 400 mg x kg(-1). This stable and reliable method will contribute to the quality control of different processed Gastrodiae Rhizoma.

OBJECTIVETo evaluate the therapeutic effect on pain in the dressing change after perianal abscess surgery treated with warm suspending moxibustion at Changqiang (GV 1).

METHODSOne hundred and sixty patients were randomized into a moxibustion group and a far-infrared therapy group, 80 cases in each one. In the moxibustion group, the warm suspending moxibustion at Changqiang (GV 1) was applied. In the far-infrared therapy group, the infrared ray was radiated at Changqiang (GV 1). The treatment started in 10 min after dressing change in the two groups. Totally, 8 treatments were required. The time requirement being equal to or less than 2 score in the assessment face scale (AFS), the case number of pain relief in 10 min after treatment and the intention of the two therapies after everyday dressing change were observed in the patients of the two groups.

RESULTSIn the moxibustion group, the time of pain relief was shorter than that of the far-infrared therapy group [(11.5 +/- 3.9) min vs (17.8 +/- 3.8) min on the 1st day; (9.4 +/- 3.6) min vs (15.2 +/- 4.3) min on the 2nd day; (7.8 +/- 2.7) min vs (14.3 +/- 3.2) min on the 3rd day; (6.4 +/- 3.3) min vs (10.5 +/- 2.9) min on the 4th day; (5.9 +/- 2.9) min vs (11.2 +/- 1.9) min on the 5th day; (5.3 +/- 2.2) min vs (8.8 +/- 2.3) min on the 6th day; (5.4 +/- 1.8) min vs (9.2 +/- 2.1) min on the 7th day; (5.1 +/- 1.4) min vs (9.5 +/- 2.6) min on the 8th day, all P < 0.05]. The case numbers of pain relief in 10 min after treatment were 74 cases, 75 cases, 77 cases and 78 cases from the 1st to the 4th day separately in the moxibustion group, which were much more than 63 cases, 65 cases, 68 cases and 69 cases in the far-infrared therapy group (all P < 0.05). The treatment intention scores in the moxibustion group were better than those in the far-infrared therapy group (all P < 0.05).

CONCLUSIONThe warm suspending moxibustion at Changqiang (GV 1) relieves pain rapidly in the dressing change of much more patients after perianal abscess surgery in much shorter time as compared with the far-infrared therapy. Moreover, the patients have more expectation to be treated with moxibustion therapy.

Objectives To analyze the diagnosis and management of steroid-resistant nephrotic syndrome (SRNS) accompanied with irreversible leukoencephalopathy in children. Methods The clinical, laboratory and imaging data were retrospectively analyzed in a SRNS child accompanied with irreversible leukoencephalopathy. A literature review was performed. Results After clinical diagnosis of SRNS, glucocorticoid, immunosuppressant, and hemodialysis were administrated for 10 months. During the course of treatment, the seizures, visual problems, and hypertension were repeatedly occured. The cranial MRI showed bilateral occipital parietal lobe hyperintensity and right frontotemporal lobe hyperintensity on T2-weighted imaging and bilateral occipital parietal lobe hypointensity on T2-Flair imaging, which indicated that encephalomalacia was accompanied with gliosis. Conclusions A variety of reasons may induce leukoencephalopathy in children. The accompanied irreversible leu-koencephalopathy should be strongly considered in management of SRNS.

Objective Atherosclerosis ( AS) is a common pathological basis of cardiovascular diseases.Adiponec-tin ( APN) has been shown to have an anti-AS effect, and the underlying mechanisms, however, are largely unknown.Nu-clear transcription factorκB ( NF-κB) has also been regarded as a proatherogenic factor, mainly because of its regulation of a variety of the proinflammatory genes linked to AS.It is hypothesized that the inhibitory effects of APN on AS is through the inhibition of NF-κB signaling pathway.The aim of this study was to test the hypothesis via investigation and validation of the inhibitory effect of APN on AS in ApoE-/-mice, and to delineate the roles of NF-κB signaling pathway in modulating the APN effect on AS in vivo.Methods APN overexpression in ApoE-/-mice were mediated by transfecting adenovirus bearing a vector encoding for APN and enhanced green fluorescent protein ( Ad-APN-eGFP) .The AS in ApoE-/-mice was induced by feeding a high-fat diet.To validate the inhibitory effect of the adenovirus mediated APN overexpression on AS in the ApoE-/-mice.120 male ApoE-/-mice aged 12 weeks were randomly and evenly assigned into two groups (60 mice per group), and were fed with a high-fat diet to induce AS.At 0 day, 2, 4, and 6 weeks of high-fat diet feeding.The 2 groups of mice were injected intravenously in the tail with either 100 μL (3.0 ×108 p.f.u) of Ad-eGFP virus ( control group) or the same amount of Ad-APN-eGFP virus ( APN group) .Blood samples and aortic tissues were taken at 0 day, 4, and 8 weeks of high-fat diet feeding.For the blood samples, FABA was used to analyze the concentrations of blood lipids and ELIZA was used to test the concentrations of serum APN.For the aortic tissues, oil red O staining was used to detect the surface lesion percentage.Masson staining was used to evaluate the collagen content and fibrous cap thickness of the plaque area.Immunofluorescence method was used to detect APN and NF-κB p65 expression.Western blot was used to de-tect the expressions of APN,nuclear NF-κB p65 and the downstream factors of NF-κB pathway.Results APN inhibited the formation of atherosclerotic plaque in ApoE-/-mice.The lesion formation in aortic sinus was significantly inhibited ( P<0.01).Compared with the control group, the oil red O staining showed that the surface area ratio of atherosclerotic le-sions was decreased significantly in the Ad-APN group ( P<0.001 ): the percentage of surface lesions in the 4 weeks groups was 27.78 ±8.64 vs.33.02 ±5.18 (%);the 8 weeks groups was 31.58 ±5.87 vs.52.16 ±5.79 (%) .As the serum APN was increased,the concentration of TC, TG and LDL-C were significantly decreased( P<0.001 for all) , and the growth of body weight was slowed down(P<0.05).APN effectively inhibited the expression of NF-κB nuclear protein p65 and inflammatory factors.Conclusions Adiponectin reduces the inflammatory reactions in atherosclerosis through in-hibiting the NF-κB pathway.

AIM:To determine the therapeutic efficacy of recombinant adenovirus containing hyper-interleu-kin-6 (HIL-6) and hepatocyte growth factor (HGF) (Ad-HGF-HIL-6) on acute-on-chronic liver failure (ACLF) in rats u-sing that of recombinant adenovirus HIL-6 or HGF ( Ad-HIL-6 or Ad-HGF) for comparison.METHODS:The rat model of ACLF was established and the model rats were randomly divided into model group, Ad0 group, Ad-HGF group, Ad-HIL-6 group and Ad-HGF-HIL-6 group.The sera and liver tissues were collected for biochemical, pathological and molecular bio-logical examinations.RESULTS:Compared with Ad0 group, prothrombin time ( PT) and the serum levels of alanine amin-otransferase (ALT), tumor necrosis factor-α(TNF-α), interferon-γ(IFN-γ) and high-mobility group box-1 (HMGB1) were markedly reduced in the ACLF rats treated with Ad-HGF, Ad-HIL-6 and Ad-HGF-HIL-6, and similarly, reduced he-patic damages and apoptotic activity, reduced Bax at protein level, and increased expression of Ki67 and Bcl-2 at protein levels were observed.Among them, treatment with Ad-HGF-HIL-6 showed the most significant therapeutic efficacy without obvious side effects.CONCLUSION:The therapeutic efficacy of Ad-HGF-HIL-6 is more potent than that of Ad-HGF or Ad-HIL-6 alone on ACLF rats with no significant side effects.

Objective:To test the expression of Minichromosome maintenance complex component 7(MCM7) protein in hepato-cellular carcinoma(HCC) of different species including human, rat and tree shrew (tupaia) by cross-species oncogenomics approach, and to investigate the relationship between the expression of MCM7 and the development of hepatocellular carcinoma and its clinical significance. Methods:Western blot and Immunohistochemistry were applied to detect the expression levels of MCM7 protein in HCC tissues,corresponding HCC-adjacent liver tissues and normal liver tissues collected from different species including human, rat and tree shrew, respectively. The clinicopathologic factors were also analyzed with the results of Immunohistochemistry. Results:Western blot analysis showed that the expression of MCM7 protein in HCC tissues of human and rat were higher than that in corresponding HCC-ad-jacent liver tissues and normal liver tissues, respectively and significantly (P<0.05). However, the expression of MCM7 protein in HCC tissues of tree shrew were also higher than that in corresponding HCC-adjacent liver tissues and normal liver tissues, but no significant difference was found among three types of tissues (P>0.05).There was also no significant difference between HCC-adjacent liver tis-sues and normal liver tissues in three species (P>0.05). Immunohistochemical analysis showed that MCM7 protein was mainly ex-pressed in nucleus of HCC cells, and the positive rate of MCM7 protein in HCC tissues of human, rat and tree shrew were significantly higher than that in corresponding HCC-adjacent liver tissues and normal liver tissues, respectively (P<0.05). However, no significant difference was found between HCC-adjacent liver tissues and normal liver tissues (P>0.05). Moreover, the protein level of MCM7 was intimately related to patient's HCC stage, extrahepatic metastases and postoperative recurrence (P<0.05). Conclusion:MCM7 protein might play a pivotal role in hepatocarcinogenesis. In addition, it was probably related to patient's HCC stage, extrahepatic metastases and postoperative recurrence. It seems very likely that MCM7 may be applied as a new molecular target in HCC prevention and treat-ment.
