Objective Improve the efficiency of radiology doctors on reading bone age films by sharing Tanner-Whitehouse(TW2)bone algorithm on the network. Methods The bone age algorithm web was Programmed with a Java script implementation of Tanner-Whitehouse Method and putted on a Web server based on HTTP service. The program allows to select a stage (from a set of 8 stages) for every bone (from a set of 20 bones), and also allows doctors to input some specific data such as birthday, sex. Based on TW2 reported values, selected and input data, the program computes the bone age. We assessed the bone ages on 50 left hand and wrist X-ray films of Chinese children aged 2-18 (1000 bones totally) with computer-aided method and manual method. The grading agreement of bone development and the time spent for bone age assessment were compared (U test) between the two methods. Results Computer-aided method is easy to use, better than manual method in accuracy of bone development grading, and it also has a friendly interface. For the 1000 bones assessed by TW2, the rate of the same maturity classification was 83.8%(838/1000), the rate of one-level maturity difference (+ 1 and - 1) was 14. 9% (149/1000), the rate of two-level maturity difference (+2 and -2) was 1.3% (13/1000). For the 1000 bones assessed by manual method, the rate of the same maturity classification was 65.7% (657/1000), the rate of one-level maturity difference (+ 1 and -1) was 27. 2% (272/1000), the rate of two-level maturity difference (+ 2 and -2) was 7.1% (71/1000). TW2 bone algorithm was significantly better than manual method (U =9.31595 ,P <0.01). The average time of assessing bone age by the two methods was 3-5 min and 15-20 min, and the TW2 method saved time for radiologists doctor. Conclusion Sharing TW2 bone age algorithm through the network can be quick and easy.

Objective To observe the difference in therapeutic efficacy between acupuncture with distant acupoints selection and proximal acupoints selection in treating acute headache.Method Sixty patients with acute headache were randomized into group A and group B, 30 cases in each group. Group A was intervened by acupuncture with distant acupoints selection, while group B was by acupoints with topical acupoints selection. The Visual Analogue Scale (VAS) and Present Pain Intensity (PPI) from McGill Pain Questionnaire (MPQ) were observed before and after intervention, and the clinical efficacies were compared between the two groups. Result After treatment, the VAS and PPI scores were significantly different from that before treatment in both groups (P<0.01). The changes of VAS and PPI scores in group A after intervention were significantly different from that in group B (P<0.01). The total effective rate was 90.0% in group A versus 73.3% in group B, and the difference was statistically significant (P<0.01). Conclusion Acupuncture with distant acupoints selection can produce a better therapeutic efficacy than acupuncture with topical acupoints selection.

Aim To investigate the protective effects of ginsenosides ( GS) on reactive oxygen species-induced oxidative damage in mouse spermatogonial cells. Meth-ods Mouse spermatogonial cell oxidative stress model was established and the attenuating effects of ginsen-osides on germ cell oxidative damage were evaluated by determination of cell viability,malondialdehyde( MDA) formation,superoxide dismutase ( SOD) activity and glutathione ( GSH) level. Results The exposure to hypoxanthine/xanthine oxidase ( HX/XO) induced an elevation in MDA,while a decrease in germ cell viability,SOD activity and GSH level. However,supplementation with GS ( 10 mg?L -1) restored HX/XO-induced decrease in cell viability,SOD activity and GSH level and HX/XO-induced increase in MDA formation. Conclusion GS may exert antioxidant activity to attenuate reactive oxygen species-induced oxidative damage in mouse spermatogonial cells.

Objective To compare the accuracy of stroke volume variation (SVV),central venous pressure (CVP) and puhnonary arterial wedge pressure (PAWP) in monitoring the changes in blood volume in the patients undergoing renal transplantation.Methods Sixteen patients with chronic renal failure,of American Society of Anesthesiologists physical status Ⅱ or Ⅲ,aged 18-55 yr,scheduled for elective allograft renal transplantation under general anesthesia,were enrolled in the study.SVV was continuously monitored with the FloTrac/Vigileo monitor,and CVP,PAWP and stroke volume index (SVI) were continuously monitored with the volumetric pulmonary artery catheter during surgery.The parameters of hemodynamics were recorded at 30 min after induction of anesthesia,5 min before renal artery opening,5 and 30 min after renal artery opening,and at the end of surgery.Hydroxyethyl starch 130/0.4 electrolyte solution 6 ml/kg was infused over 15 min via the central venous catheter to perform fluid responsiveness starting from 30 min after induction of anesthesia.Positive fluid responsiveness was defined as the change in SVI ≥ 15％.The relationship between SVV and CVP and between SVV and PAWP was analyzed using the Pearson correlation analysis.The receiver operating characteristic curve for CVP,SVV and PAWP in monitoring the changes in blood volume was drawn,and the area under the curve was calculated.Results Compared with the value at 5 min before renal artery opening,SVV was significantly increased after renal artery opening (P＜0.05),and no significant change was found in CVP and PAWP after renal artery opening (P＞0.05).SVV was negatively correlated with CVP,and r=-0.82 (P＜0.01);SVV was negatively correlated with PAWP,and r=-0.77 (P＜0.01).The area under the curve of SVV in monitoring the changes in blood volume was 0.87,and of CVP and PAWP was 0.69 and 0.66,respectively.Conclusion SVV provides better accuracy than CVP and PAWP in monitoring the changes in blood volume in the patients undergoing renal transplantation.

Objective To investigate the effect of prebiotics supplement on intestinal epithelial tight junctions and barrier function of the rats with acute pancreatitis (AP). Methods The AP model in Wistar rat was established by intraperitoneal injection of L-arginine. The rats were randomly divided into 3 groups: control group, AP group, GOS group. GOS was given 4g·kg-1·d-1at 7d before ANP induced. Twelve hours after modeling, the AP rats in each group were sacrificed. 2 ml of blood sample was taken from heart for the analysis of plasma diamine oxidase (DAO) activity. Jejunum was taken for histological examination. The transmembrane binding proteins (occludin) were measured with immunohistochemistry. Results The plasma DAO level in AP group was (7.29±0.68) U/L, and significantly higher than (2.01±0.34) U/L of control group (P＜0.01). The DAO level in GOS group was (3.44±0.59) U/L, and significantly lower than that of AP group. The occludin protein level in AP group was 95.1±9.2, and significantly lower than 44.7±8.2 of control group and 59.7±7.8 of GOS group (P＜0.01). The occludin protein level in COS group was significantly higher than that of control group (P＜0.05). Conclusions The prebiotics may increase the expression of occludin protein, enhance the intestinal epithelial tight junction, maintain the intestinal permeability, and protect the intestinal barrier function.
