Objective To investigate the efficacy of electromyographic biofeedback therapy (EMGBFT) in treating dysphagia after stroke.Methods Patients diagnosed with dysphagia after stroke were recruited and randomly divided into a control group (n =22),an electrostimulation group (ES,n =25) and an EMGBFT group (n =23).The control group received conventional treatment,while the patients in the other groups additionally received Vitalstim ES or EMGBFT 5 times per week for 3 weeks.Before and after the trial,deglutition function was evaluated through surface electromyography (sEMG) and using a standardized swallowing assessment (SSA).Results After 3 weeks of treatment,the mean sEMG amplitude,deglutition duration and SSA score and improved significantly in comparison to the baseline in all three groups.All were also significantly better in the two treatment groups than in the control group.Importantly,the mean sEMG amplitude,deglutition duration and SSA score were all significantly better in the EMGBFT group than in the ES group.Conclusion EMGBFT can promote better deglutition among patients with dysphagia after stroke more effectively than ES or conventional treatment.

[Objective] To investigate the protective effects of different extraction of Agaricus blazei Murrill on HaCaT cells damaged by UVB. [Methods] The cell viability which was detected by MTT method was used to determine the impact of different dose of UVB and different extraction of Agaricus blazei Murrill on normal HaCaT cells and HaCaT cells damaged by UVB. [Results] ①The HaCaT cells viability declined after irradiation with UVB, and it was a dose-dependent manner. The cell viability was 53.23%when the dose of UVB was 20mj/cm2. ②The water extraction at the concentration of 0.2~4mg·mL-1, aqueous extraction at the concentration of 0.1~2mg·mL-1 and crude polysaccharide at the concentration of 0.2~1mg·mL-1 could promote the proliferation of HaCaT cells, while aqueous extraction and crude polysaccharide inhibited the proliferation of HaCaT cells at higher concentrations.③The water extraction at the concentration of 1~4mg·mL-1, aqueous extraction at the concentration of 1~2mg·mL-1 and crude polysaccharide at the concentration of 0.5~1mg·mL-1 could enhance the cells viability which was irradiated by 20mj/cm2 UVB (P<0.01). [Conclusion] The different extraction of Agaricus blazei Murrill all could relieve the photo-damage caused by UVB, and it has the potential of anti-photoaging.

Objective To evaluate the clinical significance of measuring IL-13 in serum and dynamics of pulmonary function in infants with bronchiolitis.Methods A total of 50 infants with bronchiolitis(30 in acute phase,20 in recovery phase) and 20 infants in healthy controls were recruited into this study.IL-13 level in serum were detected with Sandwich enzyme linked immunosorbent assay(ELISA),at the same time the object′s respiratory function were tested,then the above indexes were compared.Results The level of serum IL-13 in recovery phase of bronchiolitis was significantly lower than that in acute phase of bronchiolitis and those of both 2 groups were significantly higher than that in control group(all P0.05).Conclusions IL-13 plays a role in pathogenesis in infants with bronchiolitis.The reduction of level of IL-13 will contribute to recovery of infants with bronchiolitis.During the acute phase of bronchiolitis higher resistance can be seen.

AIM: To evaluate the efficacy of phacoemulsification and intraocular lens implantation surgical intervention of complicated cataract in patients with uveitis.
●METHODS:Retrospective study. A total of 57 cases (57 eyes ) with complicated cataract with uveitis were involved in the study from Jan. 2015 to Dec. 2015. All cases underwent phacoemulsification and intraocular lens implantation surgery successfully. The postoperative reaction, effect, complications and so on were retrospectively analyzed after phacoemulsification and intraocular lens implantation surgery. The date of visual outcome was analyzed using Non - parametric Wilcoxon test.
●RESULTS: lris were bleed in 21 eyes ( 37%) , 4 eyes ( 7%) with posterior capsule rapture and posterior chamber intraocular lens was not implanted in 4 eyes ( 7%) . The uncorrected visual acuity ( UCVA ) was significantly increased after surgery. The UCVA of 8 eyes (14%) were 0. 1 or better before surgery, and the UCVA of 42 eyes (74%) were 0. 1 or better 3mo after surgery, the difference was statistically significant ( Z=23. 42, P<0. 001). The corneal edema (17 eyes, 30%), uveitis (2 eyes, 4%) and intraocular hypertension ( 1 eyes, 2%) were appeared in postoperative 1d. The corneal edema (3 eyes, 5%) was appeared in postoperative 1wk. The uveitis ( 1 eyes, 2%) was appeared in postoperative 1mo. The corneal edema (1 eyes, 2%), uveitis (2 eyes, 4%) , intraocular hypertension ( 1 eyes, 2%) and after-cataract ( 3 eyes, 5%) were appeared in postoperative 3mo.
● CONCLUSION: The phacoemulsification combined intraocular lens implantation surgical intervention of complicated cataract in patients with uveitis has good effect and fewer complications.

1,3-propanediol is an important chemical used as building block for the synthesis of highly promising polyesters such as polytrimethylene terephthalate. A genetically modified Klebsiella pneumoniae LDH526 can use glycerol as sole carbon source and produce 1,3-propanediol with the titer above 90 g/L. A key factor affecting the production of 1,3-propanediol by the mutant K. pneumoniae is the accurate control of the feeding of glycerol. To generate a robust and reproducible fermentation process of 1,3-propanediol, we designed and optimized an automatically feeding strategy of glycerol based on fermentation kinetics. By coupling the substrate feeding rate with easily observed variables -pH and fermentation time, we have achieved self-starting glycerol feeding and dynamic control of the glycerol concentration during the fermentation process. This automated system allowed us to generate a reproducible, consistent and operator-independent process from lab-scale to production scale. The final concentration of 1,3-propanediol was above 95 g/L after 72 h.

To study ecology suitability rank dividing of the total alkaloid content of Coptis Rhizoma for selecting artificial planting base and high-quality industrial raw material in Chongqing province. Based on the investigation of PCB and DEM data of Chongqing province, the relationship between the total alkaloid content in Coptis Rhizoma and topographical conditions was analyzed by statistical analysis. The geographic information systems (GIS)-based assessment and landscape ecological principles were applied to assess eco logy suitability areas of Coptis Rhizoma in Chongqing. slope, aspect and altitude are main topographical factors that affect the content of the total alkaloid content in Coptis Rhizoma The total alkaloid content in Coptis Rhizoma is higher in the lower altitude, shady slope and bigger slope areas. The total alkaloid content is higher in the south areas of Chongqing province and lower in the northeast. Terrain conditions of the southern region of Chongqing are most suitable for The accumulated of total alkaloid Coptis Rhizoma content.
