OBJECTIVE To design the detection system of the leaky surface acoustic wave(LSAW) biosensor in(liquid) phase and detect human papilloma virus(HPV) target sequence with the LSAW biosensor.METHODS A detection delay line and a reference delay line were constructed,the phase of the two delay line changes was(evaluated) in liquid phase,and real time monitoring of HPV reaction was performed by using the LSAW biosensor system.RESULTS The phase of the two delay lines had different changes in liquid phase;HPV could lead to a great change of the phase in the detection delay line,and reference delay line had no change.CONCLUSIONS The(detection) system of the LSAW biosensor in liquid phase is successfully constructed and real time monitoring of(detection) of HPV is realized.

One endophytic stain SS02 was isolated from the underground stems of Paris polyphylla var. Chinensis franch. The ferments of SS02 showed antibiosis activities against 13 kinds of the crop causes germs. The characteristics of morphology,physiological and biochemical showed that SS02 belonged to Bacillus sp. The 16S rDNA of SS02 was PCR and sequenced. The accession of GenBank is AY842144. The one 16S rDNA phylogenetic tree was constructed by comparing with the published 16S rDNA sequences of the relative bacteria species. In the phylogenetic tree SS02 and Paenibacillus daejeonensis was the closest relative with 97.7% sequence similarity. According to the phylogenetic analysis it was identified as Paenibacillus daejeonensis SS02.

Objective To observe the role of rosiglitazone in unclipped kidneys of two-kidney- one-clip hypertensive rats and examine its relationship to angiotensinⅡreceptors.Methods Two- kidney-one-clip hypertensive rats were divided randomly into 4 groups as follows:positive control group (CONT),traditional antihypertensive drugs group (TAHD,reserpine 50?g?kg~(-1)?d~(-1), dihydralazine 6.25 mg?kg~(-1)?d~(-1) and hydrochlorothiazide 6.25 mg?kg~(-1)?d~(-1),regular-dose rosiglitazone group (RRGL,rosiglitazone 5 mg?kg~(-1)?d~(-1)),and high-dose rosiglitazone group (HRGL, rosiglitazone 20 mg?kg~(-1)?d~(-1)).Sham operation rats were as negative controls.Each group had 8 rats. Animals were monitored and sacrificed at 10th week.Results Blood systolic pressure in TAHD group and HRGL group was significantly lower than that in CONT group [TAHD(137?27 ) mm Hg and HRGL (143?16) mm Hg vs CONT (191?25 ) mm Hg,P＜0.05],but no significant difference between the former two groups was found.Nor did the blood systolic pressure between RRGL group [(176?18) mm Hg] and CONT group.At 10th week,rats in SHAM group and treated groups had lower urinary urinary protein excretion rate,glomerular injury score and wall-to-lumen ratio of arteriole than those in CONT group [vs CONT urinary protein excretion rate (44.60?17.40) mg/24 h,P＜0.05; vs CONT glomerular injury score 60.85?33.05,P＜0.05;vs CONT wall-to-lumen ratio of arteriole 2.33?1.01,P＜0.01,except TAHD group].Though with the similar level of blood pressure,blood glucose and lipid,HRGL,compared with TAHD group showed lower urinary protein excretion rate [HRGL (16.78?3.50) mg/24 h vs TAHD (27.94?12.79) mg/24 h,P＜0.05],decreased glomerular injury score (HRGL 18.04?7.76 vs TAHD 27.92?6.39,P＜0.05) and wall-to-lumen ratio of arteriole (HRGL 1.75?0.38 vs TAHD 2.16?0.90,P＜0.05) in the cortexes of unclipped right kidneys.The expression of type 1 angiotensinⅡreceptor (AT1R) mRNA was no difference in HRGL group and TAHD group,but the expression of type 2 angiotensinⅡreceptor (AT2R) mRNA was more intensive in HRGL group.Conclusion Rosiglitazone can protect the kidneys from hypertensive injury,especially in high dose.The beneficial effects seem incompletely dependent on the metabolism modulating and reduction of blood pressure,but in relationship to the upregulation of AT2R mRNA.

Objective: To explore the mechanism of acupuncture in regulating cognitive deficits in insomnia rats by observing the effect of acupuncture on microglia in thalamic reticular nucleus (TRN). Methods: Thirty rats were randomly divided into a control group, a model group and an acupuncture group, with 10 rats in each group. The insomnia model was established by intraperitoneal injection of para-chlorophenylalanine (PCPA) once a day for 2 d. Rats in the control group were intraperitoneally injected with the same amount of normal saline. Rats in the acupuncture group received acupuncture at Neiguan (PC 6) and Zusanli (ST 36) for 5 consecutive days. The CLOCKLAB 2 data acquisition system was used to dynamically observe the sleep of the rats throughout the experiment. The cognition of rats was evaluated by event-related potentials (ERPs). After intervention, brain tissue was extracted. Immunofluorescence was used to test the fluorescence expression in TRN region. The concentrations of interleukin (IL)-1β and tumor necrosis factor (TNF)-α were detected by enzyme-linked immunosorbent assay. Results: After intraperitoneal injection of PCPA suspension, the spontaneous activity in light period of rats in the model group and acupuncture group increased significantly compared with the control group (both P<0.01). After acupuncture treatment, the rats in the acupuncture group had much less spontaneous activity during the light period than those in the model group (P<0.01), and the results indicated that acupuncture could effectively improve the sleep quality of insomnia rats. Compared with the control group, rats in the model group showed that the P3 latency, the average optical density of microglia, and the concentrations of IL-1β and TNF-α increased significantly (all P<0.05), and the P3 amplitude decreased significantly (P<0.01). Compared with the model group, rats in the acupuncture group presented that the P3 latency, the average optical density of microglia, and the concentrations of IL-1β and TNF-α were significantly decreased (all P<0.05), and the amplitude of P3 was significantly increased (P<0.05). Conclusion: Acupuncture possesses an ability to improve the cognitive state in insomnia rats. The mechanism may be related to inhibiting the microglial activation, diminishing the levels of pro-inflammatory mediators like IL-1β and TNF-α, and promoting the recovery of central nervous system function.

Objective To investigate the features of familiar facial palsy,ophthalmoplegia and dysphagia characterized by autosomal dominant inheritance in a family and to discuss the classification and pathogenesis of the disease.Methods Clinical,electrophysiological,pathological examinations were performed and blood samples were obtained from 5 patients and 26 family members.PCR protocol was used to identify a certain gene. Results In the 5 patients receiving physical examination,all had ptosis,external ophthalmoplegia,facial paralysis,dyphagia,hoarseness,decreased pharyngeal reflex;4 had amyotrophy of muscle of tongue,temporal nuscle,masseter and muscles of distal lower limbs;3 had proximal limb asthenia and distal limbs amyotrophy.Compared to those of oculopharyngeal muscular dystrophy(OPMD)with similar symptoms and signs,both electrophysiological manifestation and pathological findings of the family members supported the diagnosis of muscular dystrophy,but the(GCG)6(GCA)3GCG in the first exon of PABPN1 mutated neither in normal family members nor in patients.Conclusions This family presents clinical manifestations somewhat resembling to those of OPMD and distinctive to other disorders,but has a totally different genetic background from OPMD.It may be a new subtype of muscular dystrophy.
