Objective To investigate the molecular and cell signal transduction mechanisms by Lactobacillus cell wall extract(LCWE)inducing human-β-defensin-2(hBD-2)expression in human vaginal epithelial cells.Methods The induction of hBD-2 in human vaginal epithelial cells(WZV-1)by LCWE was observed using real-time PCR and Western blot.After stimulating WZV-1.the activation of NF-κB and p38MAPK signaling pathways were determined by Western blot.The induction of hBD-2 in WZV-1 cells by LCWE was observed with signaling pathways inhibitors of NF-κB and p38MAPK using real-time PCR and Western blot.Results The results showed that LCWE significantly upregulated hBD-2 expression in the time and dose-dependent manner.The maximal stimulatory effect of LCWE on the expression of hBD-2mRNA in WZV-1 cells were observed at the concentration of 50μg/ml after treatment for 8 h.After stimulation by 50μg/ml LCWE,Western blot analysis demonstrated that the phosphorylation of p38MAPK increased at 0.5 h significantly,peaked at 1 h,moreover the concentration of NF-κB in nucleus increased at 0.5 h significantly(P<0.05),peaked at 2 h.Blocking with inhibitor of NF-κB and(or)p38MAPK pathways results in decreased levels of HBD-2 expression.Conclusion These findings suggest that p38MAPK and NF-κB pathways play the important roles in induction of hBD-2 expression by LCWE in human vagihal epithelial cells.

Objective To examine the reliability and similarity of amplitude of low-frequency fluctuation (ALFF)for different scan duration.Methods 10 min 10 s resting state fMRI data acquired from 13 healthy volunteers separately were divided into 10 pieces of the same length.The reliability and similarity of ALFF were assessed for each scan length (1-10 min).Results Spatial maps of ALFF steadily appeared in each time period (1-10 min);but during the time evolution,both spatial distribution and extent of ALFF increased gradually.At only one minute,there were detectable statistical differences within the group.When the time ran-ging from 5 to 10 min,relatively stable ALFF results in the group achieved.Conclusion ALFF is a relatively stable index,it can be easily affected by scan duration.In the case of 1-5 min,it should be carefully analyzed and interpretated particularly.

Objective To observe the anticoagulant effect of low molecular weight heparin on induced hemodialysis in patients with acute renal failure.Method One hundred and eight patients with acute renal failure treated with induced hemodialysis were randomly divided into low molecular weight heparin(LMWH)group and unfractionated heparin(UFH)group.A bolus disc of UFH was given at first and then maintained by continuous infusion in UFH group,whereas a single bolus dose of LMWH with 2000AFXa IU to 4000AFXa IU in LMWH group.Results Anticoagulant effect between LMWH and UFH did not show significant discrepancy during induced hemodialysis.The bleeding from internal jugular vein catheter increased in the UFH group much more than that in the UFH group was significantly higher than that in the LMWH group.Anti-FXa blood levels were significantly higher in LMWH group than in UFH group.Conclusions LMWH has minor influence on aPTT and TT,while its anticoagulation effect approximates to that of UFH.LMWH represents a realistic alternative agent UFH in acute renal failure induced hemodialysis.

Objective To study the hip angle characteristics in hemiplegic gait.Methods Gait analysis was performed in 20 subjects with hemiplegia and 20 healthy subjects and the hip joint angle of all subjects was analyzed.Results The hip joint angle of affected-side lower limb of hemiplegic gait showed significant differences between 20 subjects with hemiplegia and 20 healthy subjects on hip flextion at heel-contact,maximum extension in stand phase,flextion toe-off,maximum flexion in swing phase and total excursion on sagittal plane.Conclusion The research on the characteristics of hemiplegic gait is helpful to make clinical assessment and treatment planning.

ObjectiveTo study the reliability and sensitivity of the gait analysis system based on digital video and image processing.Methods20 healthy subjects were assessed twice by the same doctor having one-week interval to investigate intraobserver reliability, they were also assessed twice separately by two doctors to investigate interobserver reliability. Gait parameters of affected limb of 20 hemiplegic patients were compared with 20 healthy subjects to investigate the sensitivity of this system.ResultsThere were high correlations in all the parameters between the two assessments. The parameters of the patients were significantly different from those of the controls.ConclusionThe system is sufficiently repeatable and sensitive in the assessment of gait.

OBJECTIVETo study clinical value of shear wave elastography (SWE) in the evaluation of neck-shoulder myofascial pain syndrome.

METHODSFrom December 2013 to July 2014,30 patients diagnosed as neck-shoulder myofascial pain syndrome were in the treatment group,including 17 males and 13 females, with an average age of (44 ± 3) years old. Thirty healthy people were in the control group, including 22 males and 8 females, with a mean age of (37 ± 5) years old. The patients in the treatment group were treated with manipulation, once every other day, total 7 times. The SWE was used to detect tension part of trapezius muscle of patients in the treatment group before and after treatment, as well as to detect muscle belly at the descending part of trapezius muscle in the control group. The tissue elasticity and Yang's modulus value were recorded and compared.

RESULTSThe tissue elasticity chart of patients in the treatment group before treatment was mainly greenish blue with the score of 3.70 ± 1.53, and the Yang's modulus was (43.4 ± 15.6) kPa. The tissue elasticity figure after treatment was mainly blue with the score of 2.40 ± 0.87, and the Yang's modulus was (29.0 ± 5.9) kPa. Whereas in the control group, the tissue elasticity figure was mainly blue with the score of 1.60 ± 0.72, and the Yang's modulus was (24.0 ± 7.6) kPa. These were statistical differences between the two groups (P = 0.000).

CONCLUSIONSWE can be used as an evaluation method of manipulation treatment for neck-shoulder myofascial pain syndrome, which is an objective and sensitive detection method.

Objective To determine the frequency of polymorphism at exon 26 (C3435T) of muhidrug resistance 1 gene (MDR1) in epileptic patients in the southern Chinese and to study the association of this polymorphism with pharmacoresistance.Methods DNA samples were obtained from 134 patients,of whom 72 were resistant to antiepileptic drug treatment and 62 were responsive to the treatment. Genotypes of the C3435T polymorphism were determined by polymerase chain reaction (PCR) followed by restriction digestion and gel electrophoresis.Genotype and allele frequencies in the drug resistant group were compared to those in the response group by Chi-square analysis.Results Of all 134 patients,33 (24.6%) had CC genotype,72 (53.7%) had CT genotype,and 29 (21.6%) had TT genotype.The frequency of CC genotype was significantly higher in the pharmaeoresistance group (33.3%) than that in the responsive group (14.5%,P=0.012).The frequency of the C allele was also significantly higher in the pharmacoresistance group (57.6%) than that in the responsive group (44.4%,P=0.03).When patients were divided by types of seizure into three groups:generalized seizure group,partial seizure group,and undefined seizure group,the CC genotype and C allele were associated with pharmacoresistance in the partial seizure group.Conclusions In the southern Chinese,the CC genotype and C allele are associated with resistance to the antiepileptic treatment.This finding needs to be verified in studies with larger sample size.

ObjectiveTo study basic pattern of normal youth in gait analysis.Methods28 healthy young persons as experimental subjects were studied. The gait analysis system based on digital video and digital image processing was employed to obtain kinematic parameters.ResultsThe means and standard deviations of kinematic parameters of normal youth were obtained. The differences of gait patterns between males and females were compared. The correlations between gait parameters and height, weight were analyzed respectively.Conclusions It is recommended that the values of the gait parameters and the trends obtained can be used as a standard gait pattern of normal youth. Statistically significant differences exist between the males and the females for most of the gait parameters. Furthermore, the differences of the values of gait parameters between the males and the females are not led only by the difference of height except very few parameters.
