Detection and antibiotic sensitivity test of Klebsiella peneumoniae in Ailurus fulgens / 中国人兽共患病学报

To confirm the etiology of a dead case for a 6 year-old female Ailurus fulgens,one strain of the predominant bacteria from pathologic tissues(heart,liver,spleen,lung and other samples) of the dead Ailurus fulgens were examined and isolated.The isolate was named R1 and no other bacteria were isolated.The bacterial etiological examination(morphological characteristics,biochemical characteristics and 16S rDNA gene detection)of R1 showed that it was identifed as K.peneumoniae.Artificial infection to mice about R1 was also conducted in this study.R1 had strong pathogenicity to mice and the LD50 is 6.5 × 104 CFU/mL.Moreover,the clinical and pathological features of the dead mice were consistent with that of the Ailurus fulgens.To find effective therapeutic drugs of curing other Ailurus fulgens,antibiotic sensitivity test of R1 was conducted,and the results revealed that R1 was highly sensitive to cefotaxime et al,moderately sensitive to amikacin and resistant to penicillin.These data showed that K.peneumoniae was bacterial pathogen leading to death of the Ailurus fulgens and it had strong resistance to penicillins,macrolides and virginiamycin and it had broad drug resistance spectrum.However,R1 is sensitive to cephalosporins and aminoglycoside antibiotics.

Risk factors for rupture of intracranial aneurysm / 中华全科医师杂志

Objective To investigate the risk factors of rupture of intracranial aneurysms.Methods Two hundred and seventy eight patients with cerebral aneurysms admitted from January 2000 to December 2013 were enrolled in study,including 122 cases with ruptured intracranial aneurysm (rupture group) and 156 cases without rupture (non-rupture group).The clinical data were collected from two groups,risk factors of aneurysm rupture were studied by univariate analysis and multivariate logistic regression analysis.Results The rates of female gender,smoking history,hypertension and atherosclerosis in rupture group were significantly higher than those in non-rupture group [70.5％ (86/122) vs.59.0％ (92/156),42.6％ (52/122) vs.29.5％ (46/156),63.9％ (78/122) vs.51.9％ (81/156) and 69.7％ (85/122) vs.51.3％ (80/156);x2 =3.943,5.175,4.034 and 4.319,respectively,all P ＜ 0.05];the width of aneurysm neck and diameter of aneurysm in rupture group were significantly lower than those in non-rupture group (all P ＜ 0.05).In addition,the rates of aneurysm rupture in patients with aneurysm diameter of ＜ 5 mm,5-8 mm and ＞8 mm were 63.4％ (64/101),40.9％ (38/93),25.0％ (20/84),respectively,Z =27.180,P =0.000;the rates of aneurysm rupture in patients with aneurysm neck width of ＜4 mm was higher than that with width ≥ 4 mm [67.3％ (66/98) vs.31.1％ (56/180),x2 =33.832,P =0.000].Multivariate logistic regression analysis showed that aneurysm diameter is an independent risk factor for rupture of intracranial aneurysm (OR =3.759,95CI:1.638-6.879,P =0.001).Conclusions The diameter of intracranial aneurysm in an independent risk factor for aneurysm rupture.Female gender,history of smoking,underlying hypertension and atherosclerosis,and the width of aneurysm neck may also related to the rupture of intracranial aneurysms.

Expression of neuropeptide Y and long leptin receptor in gastrointestinal tract of giant panda / 生物工程学报

To study the expression and distribution of neuropeptide Y (NPY) and long leptin receptor (OB-Rb) in the gastrointestinal tract of giant panda, samples of three animals were collected from the key laboratory for reproduction and conservation genetics of endangered wildlife of Sichuan province, China conservation and research center for the giant panda. Paraffin sections of giant panda gastrointestinal tissue samples were observed using hematoxylin-eosin staining (HE) and strept actividin-biotin complex immunohistochemical staining (IHC). The results show that the intestinal histology of three pandas was normal and no pathological changes, and there were rich single-cell and multi-cell mucous glands, long intestinal villi and thick muscularis mucosa and muscle layer. Positive cells expressing NPY and OB-Rb were widely detected in the gastrointestinal tract by IHC methods. NPY positive nerve fibers and neuronal cell were widely distributed in submucosal plexus and myenteric plexus, especially in the former. They were arranged beaded or point-like shape. NPY positive cells were observed in the shape of ellipse and polygon and mainly located in the mucous layer and intestinal glands. OB-Rb positive cells were mainly distributed in the mucous layer and the laminae propria, especially the latter. These results confirmed that NPY and OB-Rb are widely distributed in the gut of the giant panda, which provide strong reference for the research between growth and development, digestion and absorption, and immune function.

Expression of Translationally Controlled Tumor Protein (TCTP) Gene of Dirofilaria immitis Guided by Transcriptomic Screening

Dirofilaria immitis (heartworm) infections affect domestic dogs, cats, and various wild mammals with increasing incidence in temperate and tropical areas. More sensitive antibody detection methodologies are required to diagnose asymptomatic dirofilariasis with low worm burdens. Applying current transcriptomic technologies would be useful to discover potential diagnostic markers for D. immitis infection. A filarial homologue of the mammalian translationally controlled tumor protein (TCTP) was initially identified by screening the assembled transcriptome of D. immitis (DiTCTP). A BLAST analysis suggested that the DiTCTP gene shared the highest similarity with TCTP from Loa loa at protein level (97%). A histidine-tagged recombinant DiTCTP protein (rDiTCTP) of 40 kDa expressed in Escherichia coli BL21 (DE3) showed immunoreactivity with serum from a dog experimentally infected with heartworms. Localization studies illustrated the ubiquitous presence of rDiTCTP protein in the lateral hypodermal chords, dorsal hypodermal chord, muscle, intestine, and uterus in female adult worms. Further studies on D. immitis-derived TCTP are warranted to assess whether this filarial protein could be used for a diagnostic purpose.

The effect of group interpersonal psychotherapy on depression disorder of college students abused in childhood / 中华行为医学与脑科学杂志

ObjectiveTo study the effect of group interpersonal psychotherapy (IPT-G) on depression disorder of college students abused in childhood.Methods 28 college students meeting criteria of DSM-Ⅳ for depression disorder were divided into two groups:the treatment group( 14 patients)and the control group (14 patients).The treatment group was treated with IPT-G.Depression Symptom Checklist and Global Assessment Function(GAF) were measured in two groups before and after treatment.Results ①Patients in treatment group had better efficacy than those in control group( 100％ vs 57.1％,x2 =7.636,P ＜ 0.01 ).②The treatment factor and time factor had main effect to depression symptom and GAF(F =4.23 ～ 184.93,P ＜ 0.05 ),also had interaction effect(F=15.87 ～82.36,P ＜ 0.01 ).Time factor and abuse factor had main effect to depression symptom and GAF(F =7.44 ～ 183.9,P ＜ 0.05 ),but no interaction effect (F =0.01 ～ 4.72,P ＞ 0.05 ).③IPT-G,depression symptom and quality of life before treatment,age and only children had remarkable predictable functions on depression symptom(P ＜ 0.05).IPT-G had striking predictable functions on GAF (P ＜ 0.01 ).ConclusionIPT-G can improve depression symptom,mental and Social Function,while childhood abuse has no effect.
