ObjectiveTo investigate the clinical efficacy of coiling-dragon warm needling atHuatuo jiaji points plus Chinese herbal fumigation in treating ankylosing spondylitis (AS).MethodEighty AS patients were randomly allocated to treatment and control groups, 40 cases each. The treatment group received coiling-dragon warm needling at Huatuo jiaji points plus Chinese herbal fumigation and the control group, oral administration of salicylazosulfapyridine (SASP). An investigation was made of the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), the patients’ overall assessment, the Bath Ankylosing Spondylitis Functional Index (BASFI), the total number of swollen joints, the Bath Ankylosing Spondylitis Measurement Index (BASMI) and laboratory inflammatory indices: erythrocyte sedimentation rate (ESR), platelet (PLT) and C reactive protein (CRP).ResultThere was a statistically significant difference in the marked efficacy rate between the two groups (P<0.05). Clinical indices: disease activity index and functional index and laboratory indices: ESR, PLT and CRP improved somewhat inboth groups of patients after treatment (P<0.05). After two courses of treatment, the therapeutic effect was better in the treatment group and there was a statistically significant difference compared with the control group (P<0.05).ConclusionCoiling-dragon warm needling at Huatuo jiaji points plus Chinese herbal fumigation can effectively relieve the clinical symptoms and reduce inflammatory reactions in the active stage in AS patients. It is an effective way to treat AS.

Objective To investigate the correlation between drug-resistant genes and mobile genetic elements in multi-drug resistant Escherichia coli,and to explore phylogeny among the strains.MethodsTotally 20 strains of multi-drug resistant Escherichia coli were collected from Pan' an Hospital,Zhejiang Province during June 2009 and June 2010.Beta-lactam-resistance genes,aminoglycoside-resistance genes,genetic markers of mobile genetic elements were analyzed by PCR.Index and sample cluster analysis were performed on above results. Results In 20 strains of Escherichia coli,4 kinds of beta-lactamresistance genes,4 kinds of aminoglycoside-resistance genes,and 5 kinds of genetic markers of mobile genetic elements were detected.Index cluster analysis showed that correlation existed between resistance genes TEM,CTX-M-1,aadA5 and mobile genetic elements traA,IS26,ISEcpl; and correlation also existed between resistance genes OXA-1,aac(6′)-Ⅰ b,ant(3)-Ⅰ,rmtB and mobile genetic elements trbC,IS903.Sample cluster analysis showed that this group of Escherichia coli could be divided into 2 groups which were genetically different.ConclusionsDrug-resistant genes in multi-drug resistant Escherichia coli are correlated with mobile genetic elements.Sample cluster analysis can reveal phylogeny among the strains,which is important for hospital infection control.

Objective To investigate the effects of angiotensin Ⅱ (AngⅡ) on the expression of albumin and the synthesis of type Ⅰ collagen in human normal hepatic cells. Methods HL-7702 cells (human normal hepatocyte) were cultured and divided into control group, Ang Ⅱ treated group, an AngⅡ+irbesartan (co-stimulated) group. The expressions of albumin and type Ⅰ collagen were detected by immunofluorescence and Western blotting, respectively. The mRNA level of type Ⅰ collagen was measured by real time-PCR(qRT-PCR). Results After stimulated with 10-7 mol/L Ang Ⅱ for 72 hours, the expression of albumin significantly decreased in Ang Ⅱ treated group compared with control group (0.85±0.11 vs 1. 41±0.23,P=0.000), while the mRNA expression increased in AngⅡ treated group compared with control group (1.00±0.08 vs 3.72±0.19,P=0.000). In costimulated group, however, the expression of albumin significantly increased (0.85 ± 0.11 vs 1.38 ±0.32,P=0.000),and mRNA expression (3. 72±0.19 vs 2.86±0.13,P=0.000) and synthesis of type Ⅰ collagen were reduced when compared with Ang Ⅱ treated group. Conclusions The reduction of albumin and elevated systhesis of type Ⅰ collagen in HL-7702 cells are induced via Ang Ⅱ AT1 receptor.

To study the complete genomic sequence, genomic characteristics, and genetic variation of the bovine papillomavirus 2 genotype (BPV-2) Aks-01 strain at the molecular level, genotyping of this strain from the skin samples of cows in southern Xinjiang (China) was first detected by the polymerase chain reaction with FAP59/FAP64 primers. Based on the complete genome of the BPV-2 reference strain, specific primers and sequencing primers were designed, and the complete genome of the Aks-01 strain amplified and sequenced. Sequence analyses showed that genotyping of the Aks-01 strain belonged to BPV-2. The Aks-01 strain had the structural characteristics of BPV-2. The 7944-bp full-length genomic sequence of the Aks-01 strain was compiled using DNAStar™. The sequence of the Aks-01 strain had 98% similarity to the reference strain from GenBank. The Aks-01 strain was most closely related to BPV-1 and BPV-13. BPV-2, BPV-1 and BPV-13 were grouped within the genus Deltapapillomavirus. The Aks-01 strain is the first BPV-2 strain reported in southern Xinjiang.
