Objective To evaluate the effect of heat treatment on ultraviolet B (UVB)-induced oxidative injury to human melanocytes.Methods Melanocytes were isolated from adult foreskins,and subjected to a primary culture.After 3-4 passages of subculture,the melanocytes were classified into 4 groups:control group incubated at 37 ℃,heat treatment group incubated at 42 ℃ for 1 hour,UVB group exposed to UVB irradiation at 100 mJ/cm2,combination group receiving heat treatment at 42 ℃ for 1 hour followed by UVB irradiation at 100 mJ/cm2.After three successive days of treatment,MTT assay was performed to evaluate cell viability,a biochemical method to determine the activity of superoxide dismutase (SOD) and concentration of malonaldehyde (MDA),and flow cytometry to detect intracellular reactive oxygen species (ROS) and apoptosis in melanocytes.Results The cell survival rate,apoptosis rate,SOD activity,MDA concentration and ROS level were (100 ± 6.14)％,(4.66 ± 0.58)％,(53.39 ± 8.23) U/gprot,(1.09 ± 0.32) mmol/gprot,and 1070.85 ± 42.07 in the control group respectively.UVB exposure induced a significant increase in apoptosis rate (24.14％ ± 2.90％,P ＜ 0.001),MDA concentration (1.65 ± 0.33 mmol/gprot,P ＜ 0.01) and ROS level (1416.45 ± 79.12,P＜ 0.01),but a significant decrease in cell survival rate (50.23％ ± 5.36％,P＜ 0.01)and SOD activity (31.98 ± 1 1.89 U/gprot,P ＜ 0.01) in the UVB group compared with the control group,while the heat pretreatment markedly downregulated the UVB-induced increase in apoptosis rate (14.9％ ± 1.49％,P ＜ 0.001),MDA concentration (1.10 ± 0.26 mmol/gprot) and ROS level (1033.30 ± 68.41,P＜ 0.01),as well as the decrease in cell survival rate (74.12％ ± 6.17％,P＜ 0.01) and SOD activity (51.63 ± 6.55 U/gprot,P＜ 0.01) in the combination group.Conclusion Heat treatment could protect melanocytes from UVB-induced oxidative injury.

Objective:To detect the anti-cancer component, trans-resveratrol in red wine by high performance liquid chromatography, and to determine the influence of environmental factors on its content. Methods: A method for determining trans-resveratrol in red wine by HPLC is described. The operating conditions were ZORBAX-C18 column(4.6 mm×250 mm, 5μm) at room temperature, 30%acetonitrile as mobile phase at a flow of 1ml/min and UV detection at 306 nm. Results:The content of trans-resveratrol in Changyu dry red wine and Great Wall Claret Cabernet are (1.01±0.03)mg/L and (2.36±0.02)mg/L, respectively. The results show that, sunlight, high temperature and poor seal condition can decrease the content of trans-resveratrol. Conclusion:The content of trans-resveratrol varies in different brands of red wine. Red wine should be stored in cool, dark and sealed conditions.

Objective To master of the characteristics of development and variation in plague natural foci of Marmota sibirica, and to analyze the plague monitoring results from 2004 to 2008. Methods From May to September every year, we monitored plague in Manzhouli, Chenbaerhuqi, Xinbaerhuzuoqi, Xinbaerhuyouqi,Ewenkeqi and Yakeshi city. The monitored area was 20 000 - 40 000 hm2 in every county. The density of Marmota,ground squirrel and moonlighting rats was surveyed by path method, one-day bow-clip method and a clamp was placed every five meters, respectively. The classification and identification of ectoparasite fleas were done by using low power lens. The fleas in the ground squirrel hole were collected by flannel rubber stick, then classified and identified. According to National Standard of Plague Diagnostic Criteria(GB 15991-1995), the collected rats and fleas were detected by isolation and cultured Yersinia pestis, the serums of collected rats were tested by indirect hemagglutination test. Results In five years, the density of Marmota and ground squirrel was 0.010/hm2 and 0.602/hm2, respectively. The capture rate of moonlighting rats was 2.69％ (258/9600). The flea infection rate of Marmota was 17.54％(10/57) and the fleas index was 2.54. The fleas infection rate of ground squirrel was 28.40％(213/750) and the fleas index was 1.01. Flea infection rat of ground squirrel hole was 5.60％(46/822) and the fleas index was 0.17. The total number of various hosts of Yersinia pestis detected was 1351, the groups number of the variety of cultured fleas was 127, and the pathogen test results were negative. The number of serum tested was 1064, positive number was 43, and the detection rate was 4.04％(43/1064). The highest positive titer was 1 : 1280. Other than 2006, the remaining four years were found positive for blood clotting material; positive serum was found in a total of three regions, they were Manzhouli, Xinbaerhuzuoqi, and Xinbaerhuyouqi; and 30, 12 and 1 copies of hemagglutination-positive sera were detected. Conclusions The epidemic of plague natural foci of Marmota sibirica is in a active state, and gradually expands the scope. We must continue to strengthen the inspection of the bacteria, bearing in mind the replacement of the region's main host, make every effort to prevent and control of human plague.

AIM: To compare the clinical efficacy and safety of phacoemulsification and small incision non -phacoemulsification cataract surgery, and provide better options for clinical cataract treatment.
METHODS: According to the different operation methods, 98 cases of simple senile cataract patients in our hospital were divided into control group and treatment group, 49 cases in each. The control group received ultrasonic emulsification operation treatment; treatment group were treated by small incision non -phacoemulsification. Visual acuity, astigmatism values, average operation time, and complications were compared between two groups before and after operation.
RESULTS: There was no significant difference in preoperative corneal astigmatism values of two groups at 3mo between two groups (P>0. 05). On other times, vision and corneal astigmatism were obviously better than those before operation (P<0. 05). The average vision, corneal astigmatism values and complications incidence of two group at operation time and different postoperative time had no statistical difference (P>0. 05). When the lens nucleus hardness was at Ⅰ~Ⅲ level, corneal endothelial cell count of two groups had no significant difference ( P>0.05). When the lens nucleus hardness was at Ⅳ ~ Ⅴlevel, there was statistical difference (P<0. 05).
CONCLUSION: Small incision non-phacoemulsification cataract surgery has the similarly efficacy compared with phacoemulsification. It should be based on the actual situation of the hardness of nuclear to select the appropriate surgical treatment.
