Gum tragacanth-sodium alginate active coatings containing epigallocatechin gallate reduce hydrogen peroxide content and inhibit lipid and protein oxidations of large yellow croaker (Larimichthys crocea) during superchilling storage.

The active coatings supplemented with epigallocatechin gallate (EGCG) (0.16 %, 0.32 %, and 0.64 %, respectively) combined with superchilling storage (-3 ± 0.2 °C) were used to reduce hydrogen peroxide (H2O2) content, and inhibit lipid and protein oxidations of large yellow croaker during 42 days of superchilling storage. EGCG coatings delayed lipid and protein oxidations by inhibiting the generation of H2O2, malondialdehyde (MDA) and carbonyl groups, and maintaining a higher Ca2+-ATPase activity and sulfhydryl content. We also observed that EGCG treatments maintained myofibrillar organized secondary structure by keeping higher α-helix content, and also stabilized tertiary structure during superchilling storage. Low-field nuclear magnetic resonance (LF-NMR) revealed that EGCG treatments might improve the association of water molecules with protein for fixed water. In addition, sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and scanning electron microscope (SEM) images both showed that these treatments could delay the myofibrillar degradation of fresh fish. Overall, we report that the active coatings containing EGCG treatments protect the lipid and protein of large yellow croaker during superchilling storage.

[Analgesic and Sedative Effect of Acupuncture Combined with Medicine on Patients Undergiong Cardiac Surgery].

OBJECTIVE: To observe analgesic and sedative effect of acupuncture combined with medicine (ACM) on patients undergiong cardiac surgery. METHODS: A total of 50 patients with cardiac surgery from January 2012 to October 2014 were randomly assigned to the conventional analgesia group (group A) and the ACM analgesia group (group B), 25 in each group. Patients in group A were subjected to analgesia and sedation by injecting dexmedetomidine, while patients in group B were subjected to analgesia and sedation by electro-acupuncture [EA, Shenting (GV24); Yintang (EX-HN3)] combined with injection of dexmedetomidine. Morphine hydrochloride injection was performed when analgesia and sedation effect was ineffective in the two groups. The indicators of patients at different time points in the two groups were observed, such as static and dynamic VAS scores, SAS scores, mean arterial pressure (MAP), heart rate (HR), oxygen saturation (SpO2). The injection dosage of dexmedetomidine and morphine hydrochloride, analgesia satisfaction rate, sedation satisfaction rate, the incidences of adverse reactions during treatment such as bradycardia and low blood pressure, mechanical ventilation time, ICU time, and hospitalization expense were observed and recorded in the two groups. RESULTS: There was no statistical difference in static and dynamic VAS scores, SAS score, MAP, HR and SpO2 between the two groups at different time points (P > 0.05). The injection dosage of dexmedetomidine and morphine hydrochloride was significantly reduced in group B than in group A (P < 0.05). The analgesia satisfaction rate of patients in group B was much higher than that in group A (P < 0.05). The incidence of bradycardia also obviously decreased more in group B than in group A (P < 0.05). There was no statistical difference in patients' sedation satisfaction rate, incidences of low blood pressure, delirium, vomiting; mechanical ventilation time, ICU time, or hospitalization expense between the two groups (P > 0.05). CONCLUSION: The analgesia method of ACM could reduce the dosage of traditional analgesic drugs and the occurrence of partial adverse reactions.

[The observations of curative efficacy of rhubarb combined with blood purification on treatment patients with severe acute organophosphorus pesticide poisoning].

OBJECTIVE: To observe the curative efficacy of rhubarb, montmorillonite powder combined with blood purification on treatment for patients with severe acute organophosphorus pesticide poisoning (AOPP). METHODS: 39 patients with AOPP were divided into treatment group (received the combined treatment of rhubarb, montmorillonite powder and blood purification on the basis of routine therapy, n = 21) and control group (only received the routine treatment because of financial difficulties or the will of family members, n = 18). The differences of clinical manifestations, curative effects and prognosis between two groups were compared. RESULTS: The time of consciousness recovery, the duration of mechanical ventilation and the length of stay in hospital in treatment group were (6.5 ± 1.3), (7.9 ± 2.0) and (13.1 ± 3.2) days, which were significantly shorter than those [(8.4 ± 2.4), (10.7 ± 2.9) and (16.5 ± 3.7) days] of control group (P < 0.05). In 5, 6 and 7 day after treatment,the cholinesterase (ChE) activities of treatment group were significantly higher than those of control group (P < 0.05). The total amount and using time of atropine and pyraloxime methylchloride in treatment group were significantly smaller and shorter than those in control group (P < 0.05). The death rate of treatment group was [19.0% (4/21)], which were significantly lower than that of control group [19.0% (4/21)] (P < 0.05). CONCLUSION: The combined treatment of rhubarb, montmorillonite powder and blood purification of the AOPP patients has a better curative effect.
