Traditional Chinese ancient prescriptions have been used for treatment of liver cancer for a long history and the scientific and rational compatibility is a great wealth for modern research and development (R&D) of new drugs. The research and development of new drugs are often accompanied with a large investment, a long cycle and a high risk, especially for the anti-tumor drugs R&D which are facing more risks and lower successful rate. In this research, the regularity of compatibility of drugs was analyzed from 124 anti-hepatoma ancient prescriptions by computer program. The results can offer help to the R&D of anti-hepatoma new drugs and reduce the risk of drug screening. In addition, we surveyed 22 companies in this field from six provinces such as Beijing, Shanghai, Tianjin and so on and obtained 240 risk assessment questionaires. Then we used qualitative analysis method to interpret the greatest impacts for the risks in the process of R&D, production and sales of anti-hepatoma new drugs. The study provides a basis for anti-liver cancer drugs R&D researchers, who can take effective measures to reduce the R&D risks and improve successful rate.

Astragalus polysaccharide has been widely used in food and medicinal industry owing to its health-promoting properties. In order to characterize better the relationship among molecular weight, structure-activity and activities, a simple method was used different concentration of ethanol including 30% (PW30), 50% (PW50), 70% (PW70), 75% (PW75), 80% (PW80) and 90% (PW90) to precipitate Astragalus polysaccharides into different molecular weight. As a result, PW90 showed smooth surface and the strongest antioxidant activity among these six fractions (P < 0.05). In conclusion, graded ethanol precipitation was a simple method to separate Astragalus polysaccharides into different molecular weight with different antioxidant activity fractions.

Thyroid gland goiter of children was detected by thyroid palpation, children's urinary iodine was tested by As( Ⅲ )-Ce4+ catalytic spectrophotometry, and salt iodine was tested by direct titration. Results A total of 2919 children aged 8 to 10 were examined, 31 goiter was detected, goiter rate was 1.06%(31/2919).One thousand and seventy-eight urine samples were detected, urinary iodine median was 205.3 μg/L, that lower than 20 μg/L accounted for 1.9% (20/1078), lower than 50 μg/L accounted for 4.5%(48/1078). Two thousand and seventy-nine salt samples were detected, median of salt iodine was 32.80 mg/kg, the rate of non-iodized salt was 0.87%(18/2079), the coverage rate of iodized salt was 99.13%(2061/2079), the qualified rate of iodized salt was 98.64% (2033/2061), the consumption rate of qualified iodized salt was 97.79% (2033/2079). Conclusions Prevention and control of iodine deficiency disorders has achieved remarkable results in Xining city, all indicators have reached the national standard to eliminate iodine deficiency disorders.

OBJECTIVETo assess the efficacy and safety of Tangzu Yuyang Ointment (TYO) for treatment of chronic diabetic foot ulcers.

METHODSFifty-seven patients with chronic diabetic foot ulcers of Wagner's ulcer grade 1 to 3 were randomly assigned to the control group (29 cases) and the treatment group (28 cases). Patients in the control group received the standard wound therapy (SWT), while those in the treatment group received SWT plus TYO. The ulcer healing rate, the ulcer improvement rate and the incidence of adverse events were compared between the two groups. Totally 48 patients finished the final follow-ups and entered the data analysis.

RESULTSThe ulcer improvement rate was 79.2% in the TYO group and 41.7% in the SWT group (P=0.017) at the 12th week, and 91.7% vs. 62.5% (P=0.036) at the 24th week. There was no statistical difference in the ulcer healing rate and the incidence of adverse events between the two groups at week 4, 12, and 24, respectively. The ulcer healing time was 96 +/- 56 days in the TYO group and 75 +/- 53 days in the SWT group, showing insignificant difference (P=0.271).

CONCLUSIONTYO plus SWT was more safe and effective than SWT alone in the treatment of chronic diabetic foot ulcers.

Objective An analysis was conducted to investigate the iodine nutrition level of children aged 8 - 10 in low-coverage area of iodized salt of Yushu Qinghai province for providing a scientific basis for the development of effective preventive measures. Methods Yushu, Chengduo, Nangqian and Zaduo counties with higher non-iodized salt coverage rate in Yushu Qinghai province were chosen as survey counties in 2009. Three townships were selected in each county, and 2 primary schools were selected in each township and 40 urine samples of children aged 8-10 were collected randomly in each primary school. The content of urinary iodine was analyzed by As-Ce catalytic spectrophotometery. Results Median urinary iodine of children aged 8 - 10 in Nangqian and Zaduo was < 100 μg/L. The percentage of median urinary iodine < 50 μg/L in Yushu was over 20%. Median urinary iodine of children aged 10 in Zaduo was 81.5 μg/L, the percentage of median urinary iodine < 50 μg/L of children aged 9 and 10 was over 20%. The percentage of median urinary iodine < 50 μg/L in children aged 9 and 10 of Yushu was over 20%. Median urinary iodine of girls in Zaduo was 87.1 μg/L, the percentage of median urinary iodine < 50 μg/L of boys in Zaduo was over 20%. The percentage of median urinary iodine < 50 μg/L of girls in Yushu was over 20%. Conclusions The iodine nutrition level of children aged 8 - 10 in Nangqian, Zaduo and Yushu counties were very low due to the impact of non-iodized salt. We propose salt market in the region to strengthen management and improve the coverage and consumption rates of iodized salt to improve the level of iodine nutrition for effective prevention of iodine deficiency disorders.

OBJECTIVETo analyze the distribution of the musculoskeletal disorders, work load and working postures in different factories, gender, education levels, age and working years among manufacturing workers.

METHODSIn a cross-sectional study of 5134 manufacturing workers in 12 factories, the morbidities for musculoskeletal disorders in one year period were measured with questionnaires.

RESULTSThe morbidities for musculoskeletal disorders in body sites: waist, neck, shoulder, wrist, ankle/feet, knee, hip/buttocks and elbows were 59.7%, 47.9%, 38.1%, 33.7%, 26.9%, 25.4%, 15.2%, and 14.9%, respectively in one year period. There were significant differences of morbidities for musculoskeletal symptoms in body sites of workers among different factories (P < 0.05 or P < 0.01). The morbidities of musculoskeletal symptoms in elbows, waist, wrists and ankle/feet of the workers in refractory material and chemical fiber factories were higher than those in other factories, the morbidities for musculoskeletal symptoms of workers in garments and diamond factories were lower than those in other factories. The morbidities for musculoskeletal symptoms in neck, shoulders and wrists of female workers were significantly higher than those of male workers (P < 0.01). There were significant differences of the morbidities for musculoskeletal symptoms in body sites among workers with different educational levels (P < 0.05 or P < 0.01). There were significant differences of the morbidities for musculoskeletal symptoms in neck, shoulders, wrists, hip/buttocks and knee among groups with different age or different working years (P < 0.01), and the morbidities for musculoskeletal symptoms increased with age and working years. The proportions of unhealthy working postures and high working load among workers in refractory material and chemical fiber factories were higher; but those in garments and diamond factories were lower.

CONCLUSIONThe morbidities for musculoskeletal symptoms in waist, neck, shoulder and wrists of workers in manufacturing workers were higher; the gender, education level, age and working years could influenced the morbidities for musculoskeletal disorders.
