OBJECTIVETo study the effects of Wenyang Shengjing Decoction (WSD) containing serum on the estradiol (E2) secretion, the synthesized cytochrome P450 aromatase (P450arom) activities, as well as the expression of its encode gene CYP19 in Leydig cells of male sterile rats of adenine induced Shen-yang deficiency (SYD).
METHODSExperimental rats were randomly divided into 4 groups, i.e., the normal control group, the high, middle, and low dose WSD groups, 5 in each group. The normal saline, low, middle, and high dose WSD were respectively given to rats of all groups for 10 successive days. Blood was drawn from rats' heart 2 h after the last gastrogavage. The serum was separated after centrifuge. Leydig cells isolated and purified from SYD rats were primary cultured in vitro and divided into 5 groups in random, i. e., the blank control group, the model group, the high, middle, and low dose WSD groups (1.2, 1.0, and 0.8 g/mL, respectively). The content of E2 released in the culture supernate was determined by radioimmunoassay. The P450arom activity was detected by tritium release assay. Meanwhile, the mRNA and protein expressions of CYP19 were analyzed using fluorescent quantitative PCR and Western blot respectively.
RESULTSCompared with the blank control group, the E2 secretion of the supernate of Leydig cells obviously decreased in the model groups, accompanied with the inhibition of P450arom activities, significant decreased protein and mRNA expressions of CYP19 (P < 0.01, P < 0.05). Compared with the model group, after intervened by WSD containing serum, the E2 secretion in the Leydig cells could be significantly increased, the P450arom activities up-regulated, the CYP19 expressions up-regulated at the protein and mRNA levels partially in a dose-dependent manner (P < 0.01, P < 0.05).
CONCLUSIONSWSD containing serum could effectively elevate the E2 secretion in Leydig cells, which might be partially achieved through up-regulating P450arom activities and enhancing the gene expression of CyP19. This might be one of its mechanisms of action for treating male infertility of SYD.

OBJECTIVETo construct the body mass index (BMI) reference data and curves for Chinese children and adolescents from birth to 18 years of age.
METHODSData from two national representative cross-sectional surveys which were The National Growth Survey of Children under 7 years in the Nine Cities of China in 2005 and The Physical Fitness and Health Surveillance of Chinese School Students in 2005. Height (length was measured for children under 3 years) and weight data of 93,702 urban healthy children from nine cities/provinces used to calculate the BMI. The LMS method was used to smooth the BMI, with estimates of L, M, and S parameters, values of percentile and Z-score curves which were required were calculated, and then standardized growth charts were generated. Adult cut-offs for overweight and obesity at 18 years was used to study the cut-offs for children 2 to 18 years of age.
RESULTSThe smoothed percentiles and Z-scores reference data and curves of BMI-for-age for boys and girls aged 0-18 years were made out respectively. BMI cut-off values for overweight and obesity for children from 2 to 18 years of age were also defined. At 18 years, the BMI values are equivalent to the overweight cut-off (> or =24 kg/m2) and obesity cut-off (> or =28 kg/m2) for Chinese adults. Comparison with the reference of the WHO and 2000 CDC for the United States, there were some difference among them, at the 97th percentile curve there was a big difference between Chinese and U. S. adolescents. On the whole, the China BMI curve for boys was higher than the new WHO curve and lower than 2000 CDC at 97 percentile curve, but the China BMI curve for girls was lowest among the three curves. There was also significant difference between China and Japan BMI values at 97 percentile curve.
CONCLUSIONBMI growth curves are very useful in child growth monitoring and nutritional surveillance, discovering overweight and obesity. The BMI growth charts are recommended for use in pediatric clinic and public health service.

OBJECTIVETo construct the height and weight growth charts for Chinese children and adolescents from birth to 18 years for both clinical and preventive health care uses.
METHODSData from two national representative cross-sectional surveys which were The National Growth Survey of Children under 7 years in the Nine Cities of China in 2005 and The Physical Fitness and Health Surveillance of Chinese School Students in 2005. The data from 94,302 urban healthy children were used to set up the database of length/height (length was measured for children under 3 years) and weight. The LMS method was used to smooth the growth curves, with estimates of L, M, and S parameters, values of percentile and Z-score curves which were required were calculated, and then generated standardized growth charts.
RESULTSThe 3rd, 10th, 25th, 50th, 75th, 90th, 97th smoothed percentiles curves and -3, -2, -1, 0, +1, +2, +3 Z-scores curves of weight-for-age, length/height-for-age for boys and girls aged 0-18 years were made out respectively. Comparison with the new WHO growth charts and 2000 CDC growth charts for the United States, the results showed that there was some big difference in weight and height among the three growth charts. For boys under 15 years of age and girls under 13 years of age, the China curves are slightly higher than WHO and CDC curves, but after those ages, the China curves fall behind and the difference became larger as age progresses. At the age of 18 years, the Chinese children are 3.5 cm shorter in boys and 2.5 cm shorter in girls as compared with the U. S. children. The difference in weights are very large for the school children, especially in girls. The weight of Chinese boys was 5.9 kg less than that of the U. S. boys at 18 years, and the difference was much bigger in girls, the weight of U.S. girls between 8 to 18 years was 4.1-20.5 kg more than that of Chinese girls at the same age range.
CONCLUSIONThe new growth charts of height and weight were based on national survey data and therefore are recommended as the China national growth standards for use in pediatric clinics and public health service. Application of the charts will promote child growth monitoring, discovering early growth disorder, and will be useful to diagnosis of diseases and assessment of therapeutic effects.

OBJECTIVESTo study the inhibitory effect of KF-950 on human acrosin and sperm acrosome.
METHODSHuman acrosin was extracted and purified with 2% acetic acid, and its residual activity was evaluated by BAEE/ADH assay after treated with different concentrations of KF-950. ABC assay was used to observe the effect of KF-950 on human acrosome with Biotin-PSA as a probe.
RESULTS1. The activity of normal sperm acrosin was (37.65 +/- 4.47) U/L. 2. The residual activity was inversely related to the concentration of KF-950 (r = -0.998), and had a dose-response curve. The result could be described by Y = 7.57-1.895X. 3. With increase of KF-950 concentration and prolongation of action time, the staining rate of acrosome obviously dropped (P < 0.01).
CONCLUSIONSKF-950 directly inhibits acrosin activity and assumely injures sperm acrosome. It might be a new kind of highly effective inhibitor.

Acetylcholinesterase (AChE) inhibitors are mainly used in the treatment of Alzheimer's disease (AD). The inhibitory effect of icariin on the activity of AChE was investigated by inhibition kinetics. The binding interaction and binding sites between icariin and AChE were also studied by using fluorimetry and molecular docking, respectively. The results showed that icariin could potently inhibit the activity of AChE, the IC50 value was determined to be 3.50 x 10(-8) mol x L(-1), and the determined IC50 value to tacrine was 0.75 x 10(-8) mol x L(-1). Kinetic analyses showed that icariin is a reversible and mixed type AChE inhibitor. The inhibition constants K1 and K(IS) were determined to be 2.67 x 10(-8) and 4.43 x 10(-8) mol x L(-1), respectively. Icariin binds selectively to the AChE peripheral anionic site via hydrogen bonds and Van der Waals forces.

OBJECTIVETo evaluate the long-term results of combination treatment with Gamma Knife radiosurgery and stereotactic intracavitary brachytherapy for mixed cystic and solid craniopharyngiomas.
METHODSSixty-seven consecutive patients with mixed cystic and solid craniopharyngioma treated by Gamma Knife radiosurgery combined with stereotactic brachytherapy from October 1996 to December 2005 were selected for retrospective analysis. The inclusion criterion was the patients who survived for at least 5 years after combined treatment. There were 39 male and 28 female patients and the mean age was 31.5 years (ranged from 3 to 70 years). The clinical evaluations including neurological, neuro-ophthalmological, and neuro-endocrinological examinations, assessment of comprehensive quality of life and neuroimaging examinations were performed periodically. The actuarial survival rates and the mean survival time were calculated by using Kaplan-Meier product limit method. The rates were compared using the χ(2) test.
RESULTSFollow-up period varied from 60 to 168 months, with an average of 114 months. The tumor response rate gained from combination treatment with Gamma Knife radiosurgery and stereotactic intracavitary brachytherapy for predominantly solid and cystic craniopharyngiomas were 10/12 and 90.9% respectively, and 89.6% in all. Mean survival after combination treatment was (110 ± 9) months. The mean survival of patients with predominantly solid and cystic craniopharyngioma were (97 ± 12) months and (120 ± 14) months and the actuarial 10-year survival rates were 7/12 and 69.1%. There was no statistics difference in tumor response rate and 10-year survival rate between 2 groups of patients with predominantly solid and cystic craniopharyngioma. The actuarial 5-, 6-, 7-, 8-, 9- and 10-year survival rates were 90.5%, 85.7%, 83.3%, 76.4%, 69.4% and 60.0% respectively. The decreased visual acuity had improved in 68.3% at 6 months postoperatively and in 70.0% in long term results. Comprehensive quality of life in long term follow-up of 67 patients was excellent in 28 cases(41.8%), good in 19 cases(28.4%), fair in 17 cases(25.4%) and poor in 3 cases(4.5%), respectively. The side effects that occurred 6 to 12 months after treatment were worsening of visual acuity (4 patients), dysfunction of hypothalam (4 patients) and third nerve palsy was found in 1 patents 5 years after treatment. The rate of complications was 13.4%.
CONCLUSIONCombination treatment with Gamma Knife radiosurgery and stereotactic intracavitary brachytherapy is highly effective and safety in the treatment of mixed cystic and solid craniopharyngiomas.

Objective: To study the effect of Baoyuan Jiedu decoction on serum interleukin-6 (IL-6) content, expression of muscle atrophy F-box 1(Atrogin-1), muscle ring finger-1 (MuRF-1), uncoupling proteins-2 (UCP-2), uncoupling proteins-3 (UCP-3) in Apcmin/+ mice, in order to explore the mechanism in improving muscle atrophy in cancer cachexia model. Method: The 14-week-old Apcmin/+ cachexia mice model was randomly divided into model group, Baoyuan Jiedu decoction group (23 g·kg-1) and megestrol group (0.024 g·kg-1). C57BL/6J mice were normal group, with 10 mice in each group, and given continuous intragastric administration for 12 weeks. The quality of gastrocnemius muscle and the transverse diameter of muscle fibers were measured. The content of IL-6 in serum of Apcmin/+ cachexia mice was detected by enzyme-linked immunosorbent assay (ELISA). The expressions of Atrogin-1, MuRF-1, UCP-2, UCP-3 mRNA and protein in gastrocnemius muscle were detected by Western blot and quantitative real-time fluorescence polymerase chain reaction (Real-time PCR). Result: Compared with the normal group, the weight of gastrocnemius muscle and the transverse diameter of fibers in the model group decreased significantly (P<0.05), while the concentration of IL-6 in serum and the expressions of Atrogin-1, MuRF-1, UCP-2 and UCP-3 in gastrocnemius muscle of mice increased significantly (P<0.05). Compared with the model group, the weight of gastrocnemius muscle, the expression of UCP-3 and protein in the treated group increased significantly (P<0.05). The transverse diameter of muscle fibers increased significantly, whereas the concentration of IL-6 in serum and the expressions of Atrogin-1, MuRF-1, UCP-2 and UCP-3 in gastrocnemius muscle of mice decreased significantly (P<0.05). Conclusion: Reduction of the concentration of IL-6 in serum and the down-regulation of the expressions of Atrogin-1, MuRF-1, UCP-2 and UCP-3 genes may be the possible mechanism of Baoyuan Jiedu decoction in alleviating muscle atrophy in Apcmin/+ cachexia mice model.
