Objective To investigate the preparation process of cold -dampness medicine iron stick and the curative effect of cold -dampness medicine iron stick,thus to provide reference for the clinical treatment of cold -dampness lumbago.Methods Using science and technology of preparation and the thermal effect of cold -dampness medicine iron stick was observed.1 20 cases with cold -dampness lumbago of dampness type with low back pain, according to the order of treatment were divided into the observation group and control group.63 cases of the treatment group were given cold -dampness medicine iron stick affixed to the surface of the skin,57 cases of the control group were given kanlisha affixed to the surface of the skin.The treatment effect after one course of treatment was observed. Results Cold -dampness medicine iron stick heat effect index of heat time was 1 2min,to thermal time was 1 0.8h, the highest temperature was 56.5℃,thermal equilibrium curve was gentle and lasting.The efficacy of the two groups of drugs within the observation time effect was obvious.The total effective rate of the observation group was 90.5%(57 /63),which was higher than 75.4%(43 /57)of the control group,the difference was statistically significant (χ2 =4.87,P <0.05).During the treatment,local skin blisters,rash,itching and other low temperature burns and other allergic reaction were not found.Conclusion Cold -dampness medicine iron stick process is stable and controllable in quality and heat balance curve slow long -lasting,determine the efficacy,innovative therapies,it is easily accepted by patients and worthy to be popularized in clinical practice.

Objective This report aims to assess the exposure risk of aflatoxin B1 in edible vegetable oil in Guangxi.Methods By using margin of exposure (MOE),the report analyzes the dietary exposure of aflatoxin B1 in edible vegetable oil with the data from contamination survey and dietary intake survey.Results For the vegetable oil sample,the content of aflatoxin B1 was between 0.50-320.00 μg/kg.The detection rate of peanut oil was 78.08％ (114/146) which was higher than other vegetable oil,and the exceeding rate was 31.51％ (46/146).For peanut oil,the average content was 30.80 μg/kg,the dietary exposure of the population was 17.30 ng/kg BW,and the MOE was 18.For the prepackaged peanut oil samples,the average content of aflatoxin B1 was 6.33 μg/kg,which was below the limit.While for the bulk peanut oil,the average content of AFB1 was 41.50 μg/kg,which was more than 1.08 times of the limit,and the dietary exposure was 25.59 ng/kg BW.The MOE of bulk peanut oil was 12,1/8 of the prepackaged peanut oil.Conclusion Food safety regulators should pay more attention to bulk peanut oil products,the priority in the risk management measures.At the same time,related department should also promote healthy education for the residents.

Objective: To explore the relationship between childhood abuse, adult attachment and borderline personality disorder (BPD) in college students, and to provide reference for promoting the physical and mental health of college students. Methods: We selected undergraduate students from four colleges in Hefei, a total of 4 034 college students were surveyed by the childhood trauma questionnaire short form(CTQ-SF), the state adult attachment measure (SAAM) and the Personality Diagnostic Questionnaire(PDQ). Results: BPD was found in 4.2% of subjects, 4.5% of males and 3.7% of females. The score of BPD in non-single-parent families was lower than that in single-parent families, in families with average family economic status was lower than that in families with poor and good family economic status, and in families with medium father education level was lower than that in fathers with low and high education level(Z=-2.30, 29.25, 9.63, P<0.05). Childhood abuse, avoidant attachment and anxious attachment positively predicted BPD(β=0.21, 0.10, 0.23, P<0.01), secure attachment negatively predicted BPD(β=-0.15, P<0.01). Adult attachment played a partial mediating role in the effects of childhood abuse on BPD, with the mediating effect accounting for 16.7% of the total effect. Conclusion Adult attachment plays a mediating role in the effects of childhood abuse on BPD.
