ABSTRACT

OBJECTIVE@#To compare the efficacy of interactive scalp acupuncture, scalp acupuncture alone and scalp acupuncture plus cognitive training for cognitive dysfunction after stroke.@*METHODS@#A total of 660 patients with cognitive dysfunction after stroke were randomly divided into an interactive scalp acupuncture group (218 cases, 18 cases dropped off), a scalp acupuncture group (220 cases, 20 cases dropped off) and a scalp acupuncture plus cognitive training group (222 cases, 22 cases dropped off). All the patients were treated with routine medication and exercise rehabilitation training. The interactive scalp acupuncture group was treated with scalp acupuncture on the parietal midline, and contralateral anterior parietal temporal oblique line and posterior parietal temporal oblique line at the same time of cognitive training; the scalp acupuncture group was treated with scalp acupuncture alone, and the scalp acupuncture plus cognitive training group was treated with scalp acupuncture and cognitive training in the morning and afternoon respectively. All the treatments were given once a day, 6 times a week for 8 weeks. Montreal cognitive assessment (MoCA) scale score was used to evaluate the cognitive function before treatment, 4 weeks and 8 weeks into treatment.@*RESULTS@#Compared before treatment, the total score of MoCA was increased after 4-week treatment and 8-week treatment in the three groups (@*CONCLUSION@#The interactive scalp acupuncture could significantly improve the cognitive function in patients with cognitive dysfunction after stroke, and the efficacy is superior to scalp acupuncture alone and scalp acupuncture plus cognitive training.

ABSTRACT

Objective: Using exogenous carbon monoxide (CO) donor Hematin (H) to study the changes of photosynthesis parameters and chlorophyll fluorescence characteristics in Coptis chinensis seedlings under NaCl stress and get the way for promoting the resistance ability of C. chinensis seedlings under NaCl stress. Methods: Under 100 mmol/L NaCl stress, the several physiological indexes of C. chinensis seedlings treated by H at the different concentration, such as the contents of photosynthetic pigment and the parameters of chlorophyll fluorescence and photosynthesis, were measured. Results: Under NaCl stress the photosynthetic physiology of C. chinensis seedlings was inhibited, but the contents of chlorophyll a, chlorophyll b, total chlorophyll, and carotenoids could be obviously increased after the treatment of H at different concentration. The levels of the net photosynthetic rate (Pn), stomatal conductance (Gs), and transpiration rate (Tr) in C. chinensis seedlings were all decreased, which would gradually increase with the time and concentration increase of NaCl stress, while the concentration of CO2 (Ci) increased with the opposite tendency. These results indicated that the main influencing factor of decreasing Pn of C. chinensis was non-stomatal factors. After being treated with different exogenous substances, the Pn, Gs, and Tr were all increased in different degrees, but the level of Ci was decreased. And the maximum fluorescence (Fm), photochemical efficiency of photosystem II (Fv/Fm), potential photochemical efficiency (Fv/Fo), photochemical efficiency (Fv'/Fm'), PSII actual photochemical efficiency (ΦPSII), photochemical quenching coefficient (qP), electronic transfer rate (ETR), and photochemistry rate (PCR) were obviously increased, while the levels of minimal fluorescence (Fo), non-photochemical quenching coefficient (NPQ), and heat dissipation rate (HDR) were effectively decreased. Conclusion: Exogenous CO H with the appropriate concentration of 2.0 mmol/L could reduce the excess excitation dissipation, improve photochemical electron transport efficiency, and efficiently protect C. chinensis leaves from PSII damage by significantly alleviating the damages of salt stress to C. chinensis so that H could obviously promote the salt resistance to C. chinensis under salt stress.

ABSTRACT

Objective: To find get the method of alleviating salinity damage to Coptis chinensis under NaCl stress by studying the seed generation and seedling physiological nature. Methods: Several physiological indexes such as germination vigor, germination rate, germination index, and vigor parameters of C. chinensis were measured after treated by 5-aminolevulinic acid (ALA) under salt stress (NaCl with the concentration of 100 mmol∙L-1 NaCl). And other parameters such as memberane permeability, H2O2 content, production rate of superoxide anion, contents of soluble surge, soluble protein, free proline, and malondialdehyde (MDA), and activities of superoxide (SOD), peroxidase (POD), catalase (CAT), and ascorbate peroxidase (APX) were also measured. Results: The seed germination indexes of C. chinensis under NaCl stress have an obvious inhibition. But after the treatment of ALA, germination indexes were all increased. The results also showed that the treatment of exogenous ALA obviously increased the contents of soluble sugars, free proline, and soluble protein, decreased the contents of MDA, H2O2, and production rate of superoxide anion. Meanwhile, the results also indicated that ALA could improve the activities of SOD, POD, CAT, and APX. Conclusion: Exogenous ALA with appropriate concentration could significantly alleviate the damages to the seeds and seedlings of C. chinensis under NaCl stress and promote the salt resistance of the seeds and seedlings through improving the germination indexes and activities of anti-oxidase, decreasing the memberane permeability, and so on.

ABSTRACT

Objective To study the effects of drought stress on chlorophyll fluorescence characteristics and energy dissipation of Sarcandra glabra and get the method of alleviating drought stress, so as to provide theoretical basis against drought in planting. Methods Several physiological indexes of S. glabra treated by 5-aminolevulinic acid (ALA) under drought stress (PEG-6000 at the concentration of 15%) were measured, such as the contents of photosynthetic pigment, chlorophyll fluorescence parameters, and energy parameters. Results Exogenous ALA obviously increased the content of chlorophyll and carotenoids, enhanced the maximum fluorescence (Fm), photochemical efficiency of photosystem II (PSII, Fv/Fm), potential photochemical efficiency (FWFo), photochemical efficiency (Fv'/Fm'), PSII actual photochemical efficiency (φPSII), photochemical quenching coefficient (qP), electronic transfer rate (ETR), and photochemistry rate (PCR), as well as significnatly decreased the level of minimum fluorescence (Fo), non-photochemical quenching (NPQ) coefficient, and heat dissipation rate (HDR). The proportion of ALA absorbed light in photochemistry (P) was increased, the fraction of antenna pigment heat dissipation (D) and excess energy (E) for NPQ was decreased. The fraction off was the main pathway for excessive energy dissipation. ALA could promote the redistribution of energy reasonablely. Conclusion Exogenous ALA (100 mg/L) could significantly reduce the dissipation of excess excitation energy, improve the photochemical electron transport efficiency, and efficiently protect leaf blade of S. glabra from PSII damage under drought stress. ALA could obviously promote the drought resistance of S. glabra plantlet.

ABSTRACT

Objective To determine the distributions of major pathogenic capsular types and in vitro antimicrobial susceptibility of different serotypes of Streptococcus suis isolated from clinically healthy sows in China. Methods Tonsil specimens of clinically healthy sows from 10 different provinces in China were collected, a total of 421 S.suis were isolated. Capsular types of S.suis were decided using the sera agglutination reaction. Antimicrobial susceptibility testing was performed using a broth microdilution method and the differences between serotypes were decided statistically. Results The prevalent capsular types of S.suis isolated from clinically healthy sows were 9(26.6% ), 3 (23.5%) and 7(15.7% ) types, respectively. 7.4% of isolates were confirmed to be S.suis type 2. Overall, differences in antimicrobial susceptibility among serotypes of S. suis were found. By comparison, lower resistance was observed for S.suis type 2 from clinically healthy sows. Conclusion The prevalence of pathogenic S.suis serotypes from clinically healthy sows again indicates S.suis is a conditional pathogenic bacterium. Differential prevention and treatment regimes should be considered according to antimicrobial susceptibility of different serotypes of S.suis.
