Objective To observe the clinical efficacy of Qufeng Qingre Weiling Decoction combined with the decreasing amount of loratadine in treatment of chronic urticaria (CU). Methods Totally 108 CU patients were randomly divided into treatment group and control group, 54 cases in each group. The treatment group was given Qufeng Qingre Weiling Decoction combined with the decreasing amount of loratadine (10 mg, 1 time per day) according to symptom controlling situation, and control group with the decreasing amount of loratadine only. Both groups were treated for 4 treatment courses (2 weeks as a treatment course). Symptom score reduce index was used to calculate the effective rate after 8 weeks of treatment. And the taking antihistamine medicine score was recorded 4, 6, 8 weeks of treatment. The follow-up visits were made to observe long-term efficacy of the cured patients 1 month, 3 months and 6 months after discontinuing the medication. Results Totally 27 cases from the treatment group were cured, with a total short-term effective rate of 96.30%;13 cases from the control group were cured, with a total short-term effective rate of 65.38%, with statistical significance (P<0.05). The taking antihistamine medicine score in treatment group (0.553 ± 0.239) was lower than that in control group (0.721 ± 0.245), namely the symptom improvement in treatment group was better than that in control group by taking less antihistamine medicine. Long-term clinical efficacy showed that the treatment group was also distinctively better than the control group. Conclusion Qufeng Qingre Weiling Decoction combined with the decreasing amount of loratadine is more effective for CU, and with better short-term and long-term clinical efficacy than the control group.

OBJECTIVETo explore effect of curcumin in different concentrations on learning and memory of senescence-accelerated mice (SAM) and their possible mechanisms.
METHODSMice were randomly divided into six groups: the SAMR1 normal control group, the SAMP8 model control group, the SAMP8 + solvent (the peanut oil) control group, SAMP8 + low, middle and high dose curcumin groups. Mice were gastrogavage for 25 successive days. On the next day of ending the experiment, changes of learning and memory in mice of each group were observed by Morris water maze. The hippocampal [Ca2+] was determined. Expressions of hippocampal calmodulin-dependent protein kinase II (CaMK II) and Calmodulin (CaM) mRNA were detected using Western blot and reverse transcription polymerase chain reaction (RT-PCR) respectively.
RESULTSThe latency to find the hidden platform was remarkably prolonged, the hippocampal [Ca2+]i was markedly increased, the expression of CaMK II in the hippocampal membrane and the level of hippocampal CaM mRNA were significantly reduced in the SAMP8-model control group (P < 0.05, P < 0.01). The latency to find the hidden platform was remarkably shortened in the SAMP8 + middle dose curcumin and the SAMP8 + high dose curcumin groups (P < 0.01). The hippocampal [Ca2+]i was markedly lowered, the expression of CaMK II in the hippocampal membrane and the level of hippocampal CaM mRNA obviously increased in the SAMP8 + low, middle and high dose curcumin groups (P < 0.05, P < 0.01).
CONCLUSIONCurcumin could improve learning and memory Ca2+/capacities of SAM by lowering hippocampal [Ca2+] overload, increase the hippocampal CaM mRNA level and CaMK II expression in the hippocampal dose-dependently.

Acupuncture has remarkable effects of pain relieving and functional restoration on injuries of soft tissue and joint due to military training. As more and more attention has been attached to the impact of psychological states and biorhythm disorder on the fighting ability of military staff, acupuncture has found its place in treating chronic fatigue, combat stress reaction, traumatic brain injury and post-traumatic stress disorder as well as regulating circadian rhythms. The therapeutic effect of acupuncture in military training-related physical damage and psychological trauma has already been proved by numerous clinical practices and researches. It is held that using acupuncture as an alternative could not only save medical resources, but also enhance the fighting ability of the army. However, the current clinical studies is facing the problem of limited sample size. Therefore, randomized controlled trials in large scale and multiple centers should be further carried out toward military staff, so as to provide more speaking evidences to the prevention and treatment of physical and psychological diseases.
