A total of 152 strains of endophytic fungi were isolated from the barks of Eucommia ulmoides in three regions (Lueyang country, Zunyi country, Cili country). Based on morphological characteristics and analysis of ITS sequences, these strains were identified into 8 genera. Thereinto Phomopsis, Diaporthe and Alternaria were common genera to Eucommia barks from different sites. But the dominant genus was different: Alternaria was the dominant genus in the barks from Cili country, and Phomopsis was the dominant genus from Zunyi country, then Diaporthe was the one from Lueyang country. According to the similarity coefficient, the composition of the endophytic fungi was distinctly different between the barks from three sites. The diversity and species richness in Lueyang country and Cili country were found higher than those in Zunyi country. The evenness of endophytic fungi was 0.936 5 in Lueyang county, which was higher than 0.737 1 or 0.641 0 in Cili county or Zunyi county, respectively. After phylogenic analysis and calculating the genetic distances of typical strains belong to Phomopsis and its perfect stage--Diaporthe, there was very high genetic diversity in the two genera from our study. In conclusion, the community structure and diversity of endophytic fungi were significant different in Eucommia barks from the three habitats.

OBJECTIVETo verify the clinical efficacy of warming moxibustion on cystic acne.

METHODSNinety-four cases were randomized into an observation group, control group 1 and control group 2. The basic treatment of body acupuncture combined with fire needling was applied in all of three groups. In observation group, cone moxibustion was added on Guanyuan (CV 4), Qihai (CV 6) and Pishu (BL 20). In control group 1, Isotritinoin soft capsule was taken orally, and in control group 2, no any other therapy was administered. The efficacy, the scale change in skin lesion before and after treatment and adverse reactions were observed in three groups.

RESULTSAfter treatment, the total effective rate was 84.4% (27/32) in observation group, was 71.0% (22/31) in control group 1 and was 51.6% (16/31) in control group 2. The efficacy in observation group was superior to that in control group 2 (P < 0.05), but there was no significant difference between observation group and control group 1 (P > 0.05). The improvement in skin lesion in observation group was equal to that in control group 1 (P > 0.05), and was superier to that in control group 2 (P < 0.05). Control group 1 presented some adverse reactions, such as dry skin and cheilitis.

CONCLUSIONWarming moxibustion can improve the efficacy of body acupuncture and fire needling on cystic acne, which is equal to the efficacy of Isotritinoin soft capsule, but no any adverse reaction is induced.

BACKGROUNDAcinetobacter baumannii is one of the main gram-negative bacilli in clinical practice. Nosocomial infections caused by multi-drug resistance Acinetobacter baumannii is very difficult to treat. This study was designed to investigate the antimicrobial resistance characteristics and four resistant gene expressions of aminoglycoside-modifying enzymes including N-acetyltransferases and O-phosphotransferases in Acinetobacter baumannii.

METHODSBacterial identification and antimicrobial susceptibility test were performed by Phoenix system in 247 strains of Acinetobacter baumannii. Minimal inhibitory concentrations (MICs) of seven aminoglycosides including gentamicin, amikacin, kanamycin, tobramycin, netilmicin, neomycin and streptomycin in 15 strains of multi-drug resistant Acinetobacter baumannii were detected by agar dilution. Four aminoglycoside-modifying enzyme genes were amplified by polymerase chain reaction (PCR) and verified by DNA sequencer.

RESULTSThe resistance rates of 247 strains of Acinetobacter baumannii against cefotaxime, levofloxacin, piperacillin, aztreonam, tetracycline, ciprofloxacin and chloramphenicol were more than 50%. Imipenem and meropenem showed high antibacterial activities with resistance rates of 3.2% and 4.1%. MIC50 and MIC90 of gentamicin, amikacin, streptomycin and kanamycin in 15 strains of multi-drug resistant Acinetobacter baumanii were all more than 1024 mg/L, and the resistance rates were 100%, 100%, 100% and 93.3%, respectively. But their resistance rates to tobramycin, netilmicin and neomycin were 86.7%, 93.3% and 46.7%, respectively. Three modifying enzyme genes, including aacC1, aacC2 and aacA4 genes, were found in 15 strains, but aphA6 had not been detected. Their positive rates were 93.3%, 20.0% and 20.0%, respectively. These three genes existed simultaneously in No.19 strain. Nucleotide sequences of aacC1, aacC2 and aacA4 genes shared 100%, 97.9% and 99.7% identities with GenBank genes (AY307113, S68058 and AY307114).

CONCLUSIONMulti-drug resistant Acinetobacter baumannii strains are rapidly spreading in our hospital, and their resistance to aminoglycosides may be associated with aminoglycoside-modifying enzyme gene expressions.

OBJECTIVETo investigate the availability of serum level of macrophage clony stimulating factor (M-CSF) as a marker for early diagnosis of Alzheimer's disease (AD).

METHODSThe serum levels of M-CSF in 70 patients with AD, 52 healthy controls, 22 patients with VAD (vascular dementia) were measured and the serum levels of IL-1 beta, IL-6, TNF-alpha in 32 patients with AD and 20 controls were measured as well.

RESULTSSerum levels of M-CSF were significantly elevated in patients with AD when compared with healthy controls (P < 0.01) and VAD controls (P < 0.05) respectively. At the early stage of mild dementia and middle dementia, serum levels of M-CSF were significantly elevated, but at the later stage of severe dementia, they returned to normal level. Serum levels of IL-1 beta were significantly elevated in AD patients compared with controls (P < 0.05), and serum levels of TNF-alpha and IL-6 were within the normal range in patients with AD.

CONCLUSIONSThe results suggest that serum M-CSF level may provide a convenient and sensitive means for the early diagnosis of Alzheimer's disease.

BACKGROUNDThis study transferred a recombinant gene encoding human insulin like growth factor-1 (hIGF-1) into modified primary skeletal myoblasts with a retroviral vector (pLgXSN) and determined whether the hIGF-1 promoted growth of skeletal muscle in rat.

METHODShIGF-1cDNA was amplified in vitro from normal human liver cells by using RT-PCR and cloned into plasmid vector pLgXSN. The recombinant vector pLghIGF-1SN and control vector pLgGFPSN were transfected into packaging cell PT67 and G418 was used to select positive colony. Myoblasts were infected with a high titre viral supernatant and transduction efficiency was evaluated as GFP expression. The expression of hIGF-1 mRNA in myoblasts was investigated by immunocytochemistry and RT-PCR. MTT assays detected the growth of myoblasts in vitro. Myoblasts transduced with pLghIGF-1SN were injected into hind limb muscles of 10 - 12 week male SD rats. Formed tissues were harvested 4 weeks later. Myocyte diameter, mean weight of hind limb and body were measured to evaluate the skeletal muscle growth.

RESULTSRecombinant retroviral plasmid vector pLghIGF-1SN was constructed successfully. The titre of the packaged recombinant retrovirus was 1 x 10(6) cfu/ml. The transfection rate of PT67 cells reached 100% after G418 screening. hIGF-1 expression was positive in myoblast-IGF-1. The proliferation rate of myoblast-IGF-1 in vitro was higher than GFP-myoblast or myoblast (P < 0.05). The mean weights of hind limb and body of rats injected myoblast-IGF-1 were higher than those of the rats injected with myoblast-GFP or myoblast (P < 0.05). Myocyte diameter had a significant increase in IGF-1 group compared to GFP group and myoblast group (P < 0.05).

CONCLUSIONSThe transfection of the human IGF-1 gene mediated by a retroviral vector can promote the growth of skeletal muscle in rats. Genetically modified primary skeletal myoblasts provide a possibly effective approach to treat some skeletal muscle diseases.

OBJECTIVETo observe the effect of acupuncture combined physical training and relearning on stroke patients.

METHODSA multi-center, randomized controlled trial design was adopted. A total of 364 stroke patients were recruited and randomly assigned to the experimental group (184 cases) and the control group (180 cases). Patients in the experimental group received acupuncture combined with physical training and relearning, while those in the control group only received physical training and relearning. All received four weeks of treatment. Effects on Fugl-Meyer motor function, neurological impairment, activities of daily living difference were compared before treatment, after treatment, 2 and 5 months after follow-ups between the two groups.

RESULTSTotally 353 patients completed this trial, 179 in the experimental group and 174 in the control group. (1) compared with before treatment, brief Fugl-Meyer motor functions scores and FIM scored obviously increased, and scores for neurological impairment obviously decreased in the two group. Besides, the increment of brief Fugl-Meyer motor functions scores and FIM scores was obviously higher in the experimental group than in the control group at month 2 and 5 of follow-ups; scores for neurological impairment was obviously lower in the experimental group than in the control group. The increment of FIM scores was obviously higher in the experimental group than in the control group at month 5 of follow-ups (P < 0.05, P < 0.01). (2) There was statistical difference in inter-group comparison of total Fugl-Meyer motor functions scores and FIM scores, or scores for neurological impairment (P < 0.01). The improvement of Fugl-Meyer motor functions grading and neurological impairment grading was obviously superior in the experimental group at month 2 and 5 of follow-ups. The distribution of FIM grading was also better in the experimental group at month 5 of follow-ups (P < 0.05, P < 0. 01).

CONCLUSIONSBoth acupuncture combined exercise training and relearning and physical training and relearning could effectively promote the rehabilitation of stroke patients, reduce their neurological impairment degrees, improve motor functions and independent capacities. Better long-term efficacy could be obtained by acupuncture combined exercise training and relearning.
