The importance of rest phase and pollutant removal mechanism of tidal flow constructed wetlands (TFCW) in rural grey water treatment.

This paper explored the effects of the rest phase of tidal flow constructed wetlands (TFCW) on pollutant removal and microbial communities, and further analyzed the mechanism of TFCW removal of pollutants from grey water. The results showed that the removal rate of organic matter was 69.91 ± 2.44% in the control group (NR-TFCW) without the rest phase, 94.95 ± 1.17% in the experimental group (TFCW), and 96.95 ± 2.43% in the control group (P-TFCW) with the ventilation pipe enhanced rest phase. Limiting and enhancing the oxygen supply in the emptying stage of TFCW will enhance the overlap rate of microorganisms in the upper, middle and lower layers of the reactor. Enhancing the rest phase of TFCW leaded to better aerobic removal of organic matter in the microbial community, while limiting the rest phase of TFCW results in the opposite. In addition, the species overlap rate of the top, middle and bottom layers of NR-TFCW (69.98%) and P-TFCW (54.29%) was higher than that of TFCW (11.34%). The removal of organic matter by TFCW mainly relied on the adsorption of biochar in the flood phase, and the microorganisms aerobic degraded the organic matter adsorbed on the biochar in the rest phase. And thus form a continuous cycle of adsorption and biological regeneration. The microbial community in TFCW did not have the ability to nitrify, but had the ability to remove phosphorus. Ammonia nitrogen in the influent was adsorbed by biochar or converted into cytoplasm. While the phosphorus in the influent was adsorbed by the biochar, it was also being biologically removed.

[Clinical observation on plum-blossom needle combined with rehabilitation training for hand spasm after stroke].

OBJECTIVE: To observe the effect difference between plum-blossom needle combined with rehabilitation training and conventional rehabilitation training for hand spasm after stroke. METHODS: A total of 61 patients were randomly divided into a comprehensive treatment group (30 cases) and a rehabilitation training group (31 cases). In the rehabilitation training group, Bobath occupational therapy, OT training, and hand function training were adopted, once every day; on the basis of treatment in the rehabilitation group, plum-blossom needle was applied at the lung meridian of hand-taiyin, heart meridian of hand-shaoyin, pericardium meridian of hand-jueyin in the comprehensive treatment group. The treatment was given once every two days, three weeks as one course in the two gnoups. After 3 courses of treatment, clinical efficacy evaluation was performed, and the modified Ashworth scale and Fugl-Meyer (FMA) motor function scores were assessed before and after treatment. RESULTS: After treatment, the grade for Ashworth scale and FMA scores in the comprehensive treatment group and the rehabilitation trainning group were better than those before treatment (all P<0.05), and the improvements in hand spasm and hand fuction in the comprehensive treatment group were superior apparently to those in the rehabilitation trainning group (both P<0.05) The total effective rate of hand function was 93.3% (28/30) in the comprehensive treatment group, which was better than 74.2% (23/31) in the rehabilitation training group (P<0.05). CONCLUSION: Plum-blossom needle combined with rehabilitation training are more effective than simple rehabilitation training for hand spasm after stroke.

[Study on HPLC Fingerprint of Kanggongyan Series].

OBJECTIVE: To establish analysis methods for fingerprint of Kanggongyan series by HPLC. METHODS: A Shiseido CAP-CELL PAK C18(250 mm x 4. 6 mm, 3 µm) column was used with acetonitrile-0. 5% phosphoric acid as the mobile phase by gradient elution. The flow rate was 0. 8 mL/min, the column temperature was 30 °C, and the detection wavelength was set at 280 nm during 0 ~ 44 min and at 332 nm during 44 ~ 115 min. RESULTS: Ten common peaks were selected as characteristic peaks in the chromatogram of Kanggongyan particles, eleven common peaks were selected as characteristic peaks in the chromatogram of Kanggongyan tablets and capsules ,the similarities were greater than 0. 9 among all batches. CONCLUSION: The method is simple, steady and repeatable. It provides a basis for the quality control of Kanggongyan series.

Racemosins A and B, two novel bisindole alkaloids from the green alga Caulerpa racemosa.

Racemosin A (1), a structurally unique bisindole alkaloid possessing the seco-indolo[3,2-a]carbazole skeleton with two uncommon indolinenone units both conjugated with a methyl propenoate moiety, and its unusual cyclized derivative, racemosin B (2), were isolated from the green alga Caulerpa racemosa, together with the most commonly encountered pigment in the genus Caulerpa, caulerpin (3). Their structures were elucidated by extensive spectroscopic analysis and by comparison with data for related known compounds. A plausible biosynthetic pathway of 1 and 2 was proposed. In a neuro-protective assay, compound 1 significantly attenuated the Aß2(5-35)-induced SH-SY5Y cell damage with a 14.6% increase in cell viability at the concentration of 10µM when compared to epigallocatechin gallate (EGCG, 16.57% increase at 10 µM) as the positive control.

Clinical observation on therapeutic effects of the point-penetrating method in acupuncture treatment of spastic hemiparalysis due to cerebrovascular disorders.

OBJECTIVE: To observe the therapeutic effects of different acupuncture methods for spastic hemiparalysis due to cerebrovascular disorders. METHODS: 90 cases of spastic hemiparalysis after wind-stroke were randomly divided into a control group of 30 cases, a body acupuncture group of 30 cases and a point-penetrating acupuncture group of 30 cases. All the patients were given 4 courses of treatment, with 7 sessions constituting one therapeutic course and with a one-day interval between courses. The evaluations were made 3 times, i.e. once before treatment and once every 15 days during the treatment. RESULTS: The therapeutic effects in the point-penetrating acupuncture group were obviously superior to those of both the control group and the body acupuncture group. CONCLUSION: The point-penetrating acupuncture is an effective therapy for treating spastic hemiparalysis due to cerebrovascular disorders.
