Objective To investigate the incidence of xerostomia in patients with acquired immune deficiency syndromes (AIDS), clarify the association between AIDS and xerostomia to promote AIDS patients' oral health. Method The oral health conditions of 200 hospitalized AIDS patients were investigated by a self-designed evaluation form. Results Among 200 patients, xerostomia occurred in 113 (56.6%) . Among the xerostomia patients, 32.7% were without brushing habits, 63.7% with long-term medication and 43.1% (31 cases) with mainly antibiotics, antivirals and antifungal drugs. 30 (31.9%) patients with xerostomia were mainly associated with symptoms of oral burning, lips dry and scaly, periodontitis, oral mucosal dryness and tooth loss. Conclusions AIDS could increase the incidence of xerostomia. Some effective measures should be taken to promote patients' oral health, including improving AIDS patients' awareness of oral health, close observation of adverse reactions after treatment,looking for related causes, timely and targeted therapies,early detection and treatment of associated symptoms.

Objective The purpose of this study was to explore the effect of nursing intervention on xerostomia in patient with AIDS. Methods From October 2010 to April 2012, nursing interventions were administered in 53 AIDS patients with xerostomia during treatment. The self-designed evaluation form was used to evaluate the oral dryness of patients before and after nursing intervention. Results There were significant changes on oral dryness of patients before and after nursing invention ( < 0.01) . There was a progressive decrease in the occurrence degree of oral dryness from level 0 to level 4. The number of patients decreased by 11.4%in level 4, but increased by 9.4% in level 0. There was a positive correlation between the intervention time and treatment effect. Establishment of an effective oral care hygiene behavior intervention could help patients create a healthy lifestyle. Conclusion Nursing intervention is important to relieving xerostomia of AIDS patients.

Objective To investigate the effects of extract of Ginkgo biloba leaves EGb761 on 1-methy-l 4-phenylpyridium (MPP+)-induced injury in human neuroblastoma SH-SY5Y cells; To discuss its mechanism of action.Methods Cell culture method was used and SH-SY5Y cell damage model was induced with different concentrations of MPP+ to build Parkinson’s disease model in vitro. The experiment was divided into control group, MPP+ model group, low-, medium-, and high-dose EGb761 groups. The survival rate was determined by MTT assay, and the apoptotic rate was detected by flow cytometry according to AnnexinV apoptosis detection kit. The cell morphology was observed by inverted microscope. NO content in SH-SY5Y cells was detected by Nitric acid reduction method.Results Compared with the control group, the survival rate of SH-SY5Y cells decreased and the apoptotic rate and NO content increased in the model group (P<0.05); Compared with the model group, the survival rate of SH-SY5Y cells increased and the apoptotic rate and NO content decreased in the low-, medium- and high-dose EGb761 groups (P<0.05).Conclusion EGb761 can protect MPP+-induced SH-SY5Y cell from damage by the inhibition of the content of NO free radical.

BACKGROUND: Moxibustion can improve the symptoms of rheumatoid arthritis and reduce inflammation, but there are no uniform operation standards. The moxibustiondistance becomes one of factor influencing the therapeutic efficacy.OBJECTIVE: To compare the effects of different moxibustion distances on rheumatoid arthritis, and to explore the optimal distance.METHODS: The 8 of 40 male Sprague-Dawley rats were randomlyselected as controls. The other 32 were used to make animal modes of collagen type Ⅱ-induced ankle arthritis, and then given moxibustion at Shenshu (BL23) and Zusanli (ST36) at an interval of 1, 2 and 3 cm, respectively, once daily, 10 minutes at each point, 6 days per course for three courses, with a course interval of 1 day. Model rats with no treatment acted as model group.RESULTS AND CONCLUSION: Compared with the control group, the toe volume, arthritis index and serum levels ofinterleukin-1β and tumor necrosis factor-α except the body mass were significantly increased in the model group (P < 0.01).After moxibustion treatment, these indexes were significantly decreased in the three treatment groups (P < 0.01), especially in the 1 and 2 cm groups (P < 0.01). Narrowed articular cavity, intra-articular inflammation and pannus formation were observed in the model group, while only moderate inflammatorycell infiltration and few pannus formation were found in the 1,2, 3 cm groups. These results indicate that moxibustion improvesjoint functions and regulates immune reaction by downregulating the levels of interleukin-1β and tumor necrosisfactor-α, as well as reducing synovial hyperplasia. In addition,the optimal distance for moxibustion is 1 or 2 cm, which is amomentous proposition to improve therapeutic efficacy.

Objective: To observe the effect of different moxibustion durations on rats with rheumatoid arthritis (RA) and to evaluate the relationship between moxibustion amount and moxibustion efficacy.Methods: Eight rats were randomly selected as a normal group from the 40 male Sprague-Dawley (SD) rats, and the other 32 rats were used to establish typeⅡ collagen-induced RA models. After successful modeling, the 32 rats were randomly divided into a model group, a moxibustion for 20 min group, a moxibustion for 40 min group and a moxibustion for 60 min group, with 8 rats in each group. Rats in the normal group did not receive modeling and moxibustion intervention; rats in the model group did not receive moxibustion after modeling; rats in the moxibustion for 20 min group, the moxibustion for 40 min group and the moxibustion for 60 min group were treated with moxibustion at Shenshu (BL 23) and Zusanli (ST 36) for 20 min, 40 min and 60 min, respectively. Six days were a course of treatment, with a total of 3-course treatments and a 1-day rest between the courses of treatment. After treatment, the serum levels of interleukin (IL)-1β and tumor necrosis factor (TNF)-α, arthritis index (AI) scores, toe volumes and pathological score of synovitis were evaluated in the rats.Results: Compared with the normal group, the serum IL-1β and TNF-α levels, and the toe volumes in the model group were increased, and the differences were statistically significant (P<0.01), before the treatment. Compared with the model group, the serum IL-1β and TNF-α levels, toe volumes and arthritis index (AI) scores were significantly decreased in the moxibustion for 20 min group, the moxibustion for 40 min group and the moxibustion for 60 min group (P<0.05 orP<0.01 ). Compared with the moxibustion for 20 min group and the moxibustion for 60 min group, serum IL-1β and TNF-α levels, toe volumes and AI scores were decreased more significantly in moxibustion for 40 min group, and the differences were statistically significant (P<0.05 orP<0.01). There were no significant differences in serum IL-1β and TNF-α levels, AI scores and toe volumes between the moxibustion for 20 min group and the moxibustion for 60 min group (allP>0.05). The synovial histopathological improvement was the most obvious in the moxibustion for 40 min group, when the synovial histopathological changes were compared among the moxibustion for 20 min group, moxibustion for 40 min group and moxibustion for 60 min group.Conclusion: The therapeutic efficacy of moxibustion for 40 min in RA rats was more significant than that of moxibustion for 20 min and moxibustion for 60 min, indicating that the duration of moxibustion is the main factor affecting its therapeutic efficacy.

To ensure the quality and safety of Panax notoginseng, a method for the simultaneous determination of 10 mycotoxins in Panax notoginseng was developed using ultra performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS). The sample was extracted with acetonitrile and purified by HLB multifunction cleanup column. The separation was performed on a Phenomenex Kinetex XB-C18 column by gradient elution using methanol and 5 mmol·L(-1) ammonium acetate as mobile phase. The targeted compounds were detected in MRM mode by mass spectrometry with electrospray ionization (ESI) source operated in both positive and negative ionization modes. The linear relationships of the 10 mycotoxins were good in their respective linear ranges. The correlation coefficients (r) ranged from 0.9981 to 1.0000. The LOQs of the 10 mycotoxins were between 0.15 and 8.6 μg·kg(-1). The average recoveries ranged from 73.8% to 107.0% with relative standard deviations (RSDs) of 0.10%-10.9%. The results demonstrated that the proposed method was sensitive and accurate, and suitable for the mycotoxins quantification in Panax notoginseng.
