Objective: Huperzia serrata, whose growth is limited by high temperature, is a rare medicinal plant with the treatment function for Alzheimer's disease (AD). To research the effect of high temperature on the structure and function of cell membrane and chloroplast, and to provide the evidence for production practices. Methods: H. serrata was processed at 25, 30, 35, and 40°C, respectively, then the content changes of malondial dehyde (MDA) and conductivity rate, and the content changes of total chlorophyll, chlorophyll a, chlorophyll b, and chlorophyll a/b values were measured. The changes of the chloroplast ultra microstructure were observed under the transmission electron microscope (TEM). Results: The changes of MDA and conductivity rate in the process at 35 and 40°C were significantly higher than those of the control group; After processed at 40°C for 4 d, the total chlorophyll was decreased significantly, and became the lowest on the day 6, just was 58% compared to the control group; the change trends to the contents of chlorophyll a, chlorophyll b, and total chlorophyll were similar; TEM observation revealed that after processed at 35°C for 4 d, the chloroplast structure appeared deformation, and after processed at 40°C for 4 d, the chloroplast structure subjected obvious destruction capsule fuzzy, fracture in different degrees, thylakoid in disorder, matrix lamellar irregular, and so on. Conclusion: According to the changes of physiological index, ultramicroscopic structure, and external morphology of chloroplast, the suitable temperature for H. serrata is 25-30°C, 40°C is the limited temperature, causing death after 4 d stress, and 35°C has obvious impact on the growth, long-time stress in 35°C could also cause plant deaths.

OBJECTIVETo compare the difference in the efficacy on cervical type of cervical spondylosis (CS) between the combined treatment of sword-like needle and chiropractic spinal manipulation (the combined therapy) and the simple chiropractic spinal manipulation.

METHODSOne hundred and thirty-eight cases of cervical type of CS were randomized into a combined therapy group (76 cases) and a simple chiropractic spinal manipulation group (62 cases). In the combined therapy group, the sword-like needle therapy was applied at Fengchi (GB 20), Tianzhu (BL 10) and Jiaji (EX-B 2) C3-C5. The chiropractic spinal manipulation was used in combination. In the chiropractic spinal manipulation group, the simple chiropractic spinal manipulation was adopted. The treatment was given once every other day in the two groups, 10 days made one session. One session of treatment was required. Visual analog scale (VAS) score was observed before and after treatment in the two groups and the efficacies were compared between the two groups.

RESULTSVAS score after treatment was reduced obviously as compared with that before treatment in the patients of the two groups (both P < 0.01) and VAS score after treatment in the combined therapy group was lower than that in the simple chiropractic spinal manipulation group (1.50 +/- 0.58 vs 1.87+/-1.05, P < 0.01). In the combined therapy group, 48 cases were cured, 20 cases remarkably effective, 8 cases improved and 0 case failed. In the chiropractic spinal manipulation group, 30 cases were cured, 16 cases remarkably effective, 15 cases improved and 1 case failed. The overall efficacy in the combined therapy group was better than that in the chiropractic spinal manipulation (P < 0.05).

CONCLUSIONThe sword-like needle therapy combined with chiropractic spinal manipulation relieve effectively pain in cervical type of CS and the efficacy is superior to the simple chiropractic spinal manipulation.

Brucellosis is a zoonotic disease of global importance for infecting humans .The early diagnosis of brucellosis infection plays a significant role in the treatment and rehabilitation .This paper reviews the different methods used to diagnose brucellosis ,particularly introduces the basic principles and applications of fluorescence polarisation assay as a diagnostic tool for brucellosis ,which could provide the reference for clinical diagnosis and epidemiological investigation on brucellosis .

Objective To observe the changes of femur biomechanical properties in fluorosis rats. Methods Fifty Wistar rats of thirty-day old, weighing 90-100 g, were randomly divided according to body mass into fluorosis and control group of 25 each. Fluorosis group drank tap water containing 100 mg/L of fluoride, the control group drank tap water. The rats were observed of dental growing status and killed after feeding 6 months. Their femurs underwent tensile strength, impact, shear, bending experiments. Results The deteetable rate of dental fluorosis was significantly higher in fluorosis group[92%(23/25)] than control group[0(0/25),X2=38.97, P<0.01]. Biomeehanical data in fluorosis group(225.67±11.81,1.94±0.15,76.62±6.10,39.96.3±3.90) were lower than those of the control group(244.70±13.38,2.39±0.19,87.72±7.05,45.75±3.75) in experiments of tensile strength (MPa), impact toughness (J/mm2), shear and bending strength (MPa). The difference was statistically significant(t=3.372,5.879,3.756 and 3383, respectively, P<0.01) between the two groups. Conclusion Fluorides affected bone metabolism in rats, femur biomechanieal properties ehanged in fluorosis rats.

Objective To investigate the relation of pelvic three-dimensional conformal radiotherapy(3D-CRT) target with rectal dose distribution and irradiation volume in cervical cancer.Methods In 45 patients with cervical cancer(Ⅱa-Ⅲb) treated in our department from September to December 2006,we compared rectal dose distribution in different treatment plans: conventional radiation,4-field box radiation,4-field oblique radiation and 5-field radiation,and studied the relationship between rectal irradiation volume and dose in the target area.Results Compared with that of the other models,the dose distribution of CTV in 3D-CRT was relatively poor although it could satisfy the demand of treatment;dose distribution of D90,D80 and D50 in the radiated rectum differed significantly(P

Objective To determine the dietary nutritional status of rural residents in Midwestern Shandong Province,in order to improve the dietary pattern and health status of them.Method 11 987 residents,from 10 273 households,were included in this study by multi-stage randomized cluster sampling in 8 counties located in Midwestern Shandong Province.Questionnaire of Food Frequency (QFF) was applied to collect the information about the amount and frequency of food consumed by the subjects in the past year.Results The average intake of cereal,vegetable,fruit,meat,egg,milk,bean,oil and salt per reference man per day was 553.9 g,310.6 g,58.2 g, 36.3 g,50.1 g,16.7 g,34.4 g,44.8 g and 12.3 g,respectively.The average intake of energy,carbohydrate,protein,fat and dietary fiber per reference man per day was 12 095.6 kJ,451.8 g,85.6 g,78.8 g and 18.7 g as well Cereal food provides 66.1% of total energy; however,the meat provides only 6.6% of that.Carbohydrate,protein and fat amount to around 63.2%,12.0% and 24.8% of total energy, respectively.24.0% of fat intake was from animal food,while 76% of that was from vegetable food.Conclusions The intake of energy, protein,fat was sufficient for these subjects;however,the intake of vegetable,fruit,bean and meat was lower than the dietary reference intake.Moreover,oil and salt intake in these subjects was much higher than Chinese Recommended Nutrient Intakes.Thus,the amelioration of dietary pattern in rural residents will be an important task for nutrition workers in rural area of Midwestern part of Shandong Province in the future.
