Doctor's degree is the highest degree for medical education.Nowadays,medical doctor candidates in more and more medical universities are requested to publish research papers in intemational journals embodied in Science Citation Index(SCI),or they can not graduate with doctor's degree.So,it is significant for medical doctor candidates to learn the related knowledge about SCI and Impact Factor(IF).

Objective To observe the effects of stationary cycle training on lower limb muscle tension and motor function in children with spastic cerebral palsy.Methods Sixty-seven children with spastic cerebral palsy were divided into a treatment group (n =34) and a control group (n =33).Both were treated with routine rehabilitation therapy,including neurodevelopment treatment,massage and physical agent therapy.The treatment group additionally cycled on a stationary bicycle for 20 min a day,five days a week for 3 months.Muscle tension in the children's adductor,hamstring and gastrocnemius muscles was evaluated using the modified Ashworth scale (MAS),while the adductor angle,popliteal fossa angle and foot dorsiflexion angle were measured using a joint protractor.Moreover,the 88-item version of the Gross Motor Function Measure (GMFM-88) was used to evaluate gross motor function.Results After treatment the average muscle tension of both groups was significantly lower than before treatment.The average muscle tension scores of the adductors,hamstrings and calf muscles of the treatment group [(1.79±0.54),(1.00±0.60),(2.29 ±1.77)] were significantly lower than those of the controls [(1.82 ± 0.53),(1.15 ± 0.44),(2.52 ± 1.89)].The adductor angles,popliteal fossa angles and foot dorsiflexion angles of both groups were significantly larger than before treatment,and the angles in the treatment group [(97.06 ± 19.03) °,(53.38 ± 12.54) ° and (8.38 ± 9.11) ° respectively] were significantly larger on average than those in the control [(98.94 ± 21.42) °,(56.52 ± 12.90) ° and (5.30 ± 14.30) ° respectively].After treatment the total GMFM scores of both groups were better than before treatment,but the treatment group's average score(138.18 ± 54.86) was significantly better than that of the control group(112.21 ± 62.44).Conclusion Three months of stationary cycle training can effectively reduce the muscle tension of children with spastic cerebral palsy and improve their motor function.

Objective To investigate the beneficial effect on enterocyte-like cells HT-29 through adhesion of Lactobacillus. Methods Using viable bacteria counting method to evaluate inhibition of Escherichia coli adhesion and invasion to enterocyte-like cells by incubation with Lactobacillus together. Cellular membrane permeability and cell viability were examined in vitro by LDH level and MTT method respectively. Results Adhesion and invasion of enteropathogenic Escherichia coli to enterocyte-like cells was inhibited by high adhesiveness strain Lactobacillus reuteri JCM1081. In vitro, no significant changes of the morphology, structure and function of the HT-29 cells after being treated with Lactobacillus alone for 3 hours, especially cellular LDH level, viability and membrane permeability. Lactobacillus reuteri JCM1081 did not alter cell integrity and prevented the increase in permeability induced by enteropathogenic Escherichia coli infection. Conclusion Lactobacillus reuteri JCM1081 interact with intestinal epithelial cell receptor to competitively inhibit the adhesion and invasion of enteropathogenic Escherichia coli to HT-29 cells by incubation and enhance the integrity of the cells.

Objective To explore the molecular mechanism of hypophrenia induced by Down syndrome (DS).Methods Ts65Dn mice were used as DS animal model.Three female mice and three male mice of three to twelve weeks old were mated.Among the 17 first-generation mice alive,five mice remained Ts65Dn trisomy and 12 mice were normal.Five Ts65Dn mice and five normal mice were selected randomly as Ts65Dn group and control group,and bred till 16 to 18 weeks old for experiments.Differential proteins in hippocampus of mice were tested by isobaric tags for relative and absolute quantitation (iTRAQ).Expressions of the differential proteins in Ts65Dn group were detected compared with those in control group.Results A total of 2805 proteins were identified in hippocampus of Ts65Dn group and control group,and significant differences were observed in the expressions of 374 proteins.Compared with those in control group,expressions of 195 proteins increased and 179 reduced in Ts65Dn group.Sorted by P value from low to high,the seven proteins with the lowest P value were uncharacterized protein C2orf47 homolog,isoform 2 of filamin A-interacting protein 1-like,zinc finger protein,isoform 1 of pericentriolar material 1 protein,SEC23 interacting protein,BAG family molecular chaperone regulator 3 and serpin H1.Conclusions Differential proteins are observed in hippocampus of Ts65Dn mice,perhaps closely correlating to neurological defects.The new technology of iTRAQ helps to screen and identify differential proteins in hippocampus.

Objective To retrospectively review the efficacy and side effects of intense pulsed light (IPL) and red light emitting diode (LED) in the treatment of steroid-dependent dermatitis.Methods Seventy patients with steroid-dependent dermatitis mainly manifesting as facial telangiectasis were treated with IPL for an average of 3.49 sessions with a 4-week interval.The energy density of IPL varied from 20 to 23 J/cm2,pulse width from 2.6 to 5.0 ms,and delay from 15 to 20 ms.Meantime,197 patients with steroid-dependent dermatitis,who mainly presented with facial skin sensitivity,were treated with red LED (633 ± 3 nm wave length) twice a week for an average of 4.23 sessions.The energy density of red LED was 128 J/cm2,and the irradiation lasted 20 minutes at each treatment.The efficacy and adverse reactions were assessed and recorded for each treatment.Results The total response rate was 88.57％ for IPL,and 83.76％ for red LED.There was a significant difference in the clinical efficacy between triple-pulse and double-pulse IPL (x2 =8.14,P ＜ 0.05).No severe adverse reaction was observed in any of the patients.Conclusion IPL and red LED are both effective in treating steroid-dependent dermatitis.

Objective: To compare the effects of traditional and limited resuscitation on mediators of inflammation and the lung injury in a rat model of hemorrhagic shock. Methods: Seventy-two male Spra-gue-Dawley rats were challenged with hemorrhage followed by unresuscitation or resuscitation with 6 mL/kg blood withdrawl and lactated Ringer's solution of 45 mL/(kg · h) ,30 mL/(kg · h) or 15 mL/ (kg · h). Rats were sacrificed at 24 hrs, 48 hrs and 72 hrs, respectively. Blood was withdrowed for testing plasma levels of lactic acid and TNF-α. Lungs were harvested for observation of the ratio of wet/dry weight and histology. Results: The unresuscitation group were dead within 2 ～ 12 hrs, while the resuscitation groups were survival. The MAP of group 15 mL/(kg · h) increased slowly, but the MAP of 30 and 45 mL/(kg · h) groups increased rapidly. The plasma levels of TNF-α at 24 and 72 hrs and the lactic acid at 24 hrs in group 45 mL/(kg · h) were higher than that of group 15 and 30 mL/(kg · h) (P < 0. 05). The ratio of W/D weight of lungs at 48 and 72 hrs in group 15 mL/(kg · h) was lower than that of group 45 and 30 mL/(kg · h)(P<0.05). The lung injury was alleviated in pace with the time elapsing. The lung injury was more severe in group 45 mL/(kg · h) than the other two groups in 24, 48 and 72 hrs(P <0. 05). Conclusion: Limited fluid resuscitation could decrease the plasma levels of TNF-α and lactic acid,and attenuate the lung injury.
