Objective To evaluate the effects of dexmedetomidine on the cellular immune function of the rats with scald.Methods Seventy-two healthy male Sprague-Dawley rats,weighing 200-220 g,aged 120-150 days,were randomly divided into 3 groups (n =24 each):normal control group (group C),scald group (group S) and dexmedetomidine group (group D).Thirty percent of the total body surface was shaved and then exposed to 94 ℃ water for 12 s in S and D groups.The rats were resuscitated according to Parkland formula after scald in S and D groups,and in addition,dexmedetomidine 30 μg/kg was also intraperitoneally injected immediately after scald in D group.Before the model was established (T1) and at 12 and 24 h after scald (T2,3),blood samples from the inferior vena cava were collected for determination of T lymphocyte subsets CD3 +,CD4 + and CD8 +,NK cell,C-reactive protein (CRP),interleukin-6 (IL-6),IL-10 and tumor necrosis factor-alpha (TNF-α) level.CD4+/CD8+ was calculated.Arterial blood samples were collected for blood gas analysis.Results Compared with C,the CD3+,CD4+ and NK cell levels,CD4+/CD8+,pH value,PaCO2 and PaO2 were significantly decreased,and CD8+ levels,IL-6,IL-10,TNF-α,CRP and BE negative value were increased at T2,3 in S and D groups.Compared with group S,the CD3+,CD4+,NK cell and IL-10 levels,CD4+/CD8+,pH value,PaCO2 and PaO2 were significantly increased,and CD8+ levels,IL-6,TNF-α,CRP and BE negative value were decreased at T2,3 in group D.Conclusion Dexmedetomidine can improve the cellular immune function of the rats with scald.

OBJECTIVETo observe the effects among aconite cake-separated moxibustion, moxibustion and acupuncture for knee osteoarthritis (KOA) with kidney-marrow deficiency and to explore the feasibility of cake-separated moxibustion as a home remedy solution.

METHODSNinety patients were randomized into an aconite cake-separated moxibustion group, a moxibustion group and an acupuncture group, 30 cases in each one. The acupoints in the three groups were Neixiyan (EX-LE 4), Dubi (ST 35) in the affected side, and bilateral Xuehai (SP 10), Liangqiu (ST 34), Heding (EX-LE 2), Shenshu (BL 23) and Zusanli (ST 36). All the treatment was given for 3 sessions, 10 days as a session with 2 to 3 days between 2 sessions, and once a day. The first 2 courses of aconite cake-separated moxibustion was applied in the hospital and the other 1 session was used at home guided by officer physician. Symptoms and physical signs classification score and life quality scores were recorded before and after treatment and 6 months after treatment, including walking pain, knee pain in stoop and squat, knee discomfort in stair activity and daily discomfort. The effects were evaluated.

RESULTSThe symptoms and physical signs classification scores in the three groups after treatment and at follow-up were lower than those before treatment (<0.01,<0.05), and the scores in the aconite cake-separated moxibustion group were better than those in the moxibustion group and acupuncture group (all<0.01). The scores of walking pain, knee pain in stoop and squat, knee discomfort in stair activity and daily discomfort were lower in the three groups after treatment and 6 months after treatment (<0.01,<0.05), and the scores of walking pain and daily discomfort in the aconite cake-separated moxibustion group were lower than those in the moxibustion group and acupuncture group (<0.01,<0.05). After treatments, the cured and markedly effective rate in the aconite cake-separated moxibustion group was 63.3% (19/30); that in the moxibustion group was 50.0% (15/30) and one in the acupuncture group was 43.3% (13/30). The cured and markedly effective rate of aconite cake-separated moxibustion group was more promising than those in the other two groups (both<0.05). At follow-up, the cured and markedly effective rate in the aconite cake-separated moxibustion group was 56.7% (17/30), which was better than 36.7% (11/30) in the moxibustion group and 40.0% (12/30) in the acupuncture group (both<0.05).

CONCLUSIONAconite cake-separated moxibustion can be used for KOA patients with kidney-marrow deficiency, which can improve patients' life quality and is better than moxibustion and acupuncture. The method is feasible as a home remedy solution.

Objective To study the antifungal activity of phenazines derivatives. Methods The anti-fungal activity of phenazine compounds was evaluated initially with micro-liquid dilution. No significant antifungal activity against Candida albicans was found. Then, with the combination of phenazine compounds and fluconazole, the anti-fungal activity against fluconazole-resistant C. albicans was detected. Results The phenazine-17 had significant antifungal activity when combined with fluconazole through the inhibition of hyphae formation. Conclusion This study provides a new idea for the development of antifungal drugs and the solution of antifungal drug resistance.
