Objective To explore the relationship between skin photo reactions and structural pa-rameters. Methods Benzophenone-1, Benzophenone-2 and Benzophenone-3 were assessed by phototoxici-ty test and photoallergic test on guinea pig. And the phototoxicity index and photoallergic index were cal-culated after clinical assessment. Structural parameters of the three sunscreens like total energy, binding energy, electronic energy, heat of formation, dipole and sum of the net charges were also calculated by the soft of HyperChem7.0, respectively. Results The phototoxicity index rised with total energy, elec-tronic energy and sum of net charges increasing. And the photoallergy index rised only with binding ener-gy increasing. So there was some correlation between phototoxicity index and total energy, electronic en-ergy and sum of net charges (P<0.01). Significant relationship was only between the photoallergy index and binding energy (P<0.01). Conclusions The phototoxicity is correlated with total energy and e-lectronic energy, while photoallergy is related to binding energy. It is possible to establish a model evalua-ting the safety and structural parameters of benzophenone ramifications.

Objective To observe the effect of Tongfu Xiere Recipe (TXP) combined with routine treatment on cytokine level in patients with acute lung injury due to surgery disease of chest. Methods Fifty eight patients with acute lung injury due to surgery disease of chest were randomized into two groups. The two groups received routine treatment subjecting to the Guideline (2006) for Diagnosis and Treatment of Acute Lung Injury/Acute Respiratory Distress Syndrome. The treatment group additionally received TXP (mainly composed of Radix et Rhizoma Rhei, Natrii Sulfas, Fructus Gardeniae, Caulis Lonicerae, Herba Taraxaci, Semen Raphani, Semen Lepidii seu Descurainiae, Rhizoma Polygoni Cuspidati, Radix Paeoniae Rubra, Fructus Aurantii Immaturus, and Cortex Magnoliae Officinalis) for 5 days or till oxygenation index recovered to the normal. The therapeutic effect was evaluated after treatment, and the changes of blood tumor necrosis factor ? (TNF-?), interleukin 6 (IL-6) and interleukin 8 (IL-8) levels were observed before and after treatment. Results The serum levels of TNF-?, IL-6 and IL-8 in the two groups after treatment were decreased (P0.05). Conclusion The therapeutic effect of traditional Chinese medicine integrated with western medicine is superior to the western medicine only for acute lung injury due to surgery disease of chest. TXP can regulate the immune function and relieve the pulmonary inflammation and injury by decreasing the blood levels of TNF-?, IL-6 and IL-8, thus enhance the therapeutic effect of western medicine.

OBJECTIVETo investigate the risk factors for contact dermatitis in pig farm workers.

METHODSThe cross-sectional questionnaire survey and on-site survey were conducted in pig farms raising more than 50 pigs in a county of Fujian Province, China. The study subjects were grouped based on different factors. The incidence rate was compared between groups by statistical analysis.

RESULTSOf 302 subjects, 70 (23.18%) had contact dermatitis. There was a significant difference in the prevalence of contact dermatitis between the subjects in direct contact with commercially available pannage and those in indirect contact (χ(2) = 14.552, P < 0.01). Region, season, farm scale, brand of pannage, and allergic history were not influential factors for contact dermatitis (P > 0.05 for all).

CONCLUSIONDirect contact with commercially available pannage is closely associated with contact dermatitis in pig farm workers.
