OBJECTIVETo investigate the type and corresponding operation methods of ulnar lateral mass in distal radial fractures.

METHODSFrom January 2004 to September 2010,32 cases of distal radial fractures with ulnar lateral mass were treated by surgical incision and relocate ulnar lateral mass,including 23 males and 9 females with an average age of (34 +/- 9) years old ranging from 28 to 65 years old. According to the classification of Melone-Doi, 2 cases with type I, 24 cases of type II, 6 cases with type III. The operative appoach involved palm-radial, palm-ulnar, radial-dorsal. Among them, 28 patients with closed fractures were fixed with plate, 4 cases (including 2 cases of open fractures) were fixed by Kirschner pin and braces.

RESULTSThirty-two patients were followed up for 8 to 18 months with an average of 12 months. All fractures were healing without complications. According to modified Gartland-Werley scoring system (GWSS), the total score was 1.12 +/- 0.45, the remain deformity was 0, subjective evaluation was 0.50 +/- 0.30, objective evaluation was 0.30 +/- 0.21, complications was 0.40 +/- 0.09; the result was excellent in 21 cases, good in 11 cases.

CONCLUSIONThe location of ulnar lateral mass in distal radial fractures is one of the important prognostic factors in wrist function and surgical treatment is an effective method of fixing ulnar lateral mass in distal radial fractures.

Objective To establish the methods for quantitating the circulating tumor DNA with PicoGreen fluorescent nucleic acid stain and investigate the role of the quantitative analysis in diagnosis of breast cancer. Methods Circulating tumor DNA was isolated from serum with QIAmp blood kit and was quantitated by spectrofluorometry with PicoGreen fluorescent stain. Receiver operator characteristic ( ROC) curve and area under the curve were used to estimate the role of DNA quantification in diagnosis of breast cancer. Results The efficiency of QIAamp blood kit isolating DNA from serum was 37. 8%-46. 2%, average 43. 4%. Circulating tumor DNA concentration as low as 1 ng could be detected by PicoGreen spectrofluorometry. and the detected range was 1-500 ng/0. 2 ml. The median concentration of serum DNA in breast cancer group was (169. 70+ 124. 10) μg/L, and that of healthy control and breast benign group were (54. 30±36. 84) μg/L and (51. 70±29. 04) μg/L, respectively (P<0. 01). The area under the ROC curve was 0. 899 (95% CI: 0.848-0.951), and the sensitivity was 78. 2%, the specificity was 90% by using the cutoff value of 96. 0 ng/ml. Conclusions The concentration of circulating tumor DNA can be efficiently quantitated by PicoGreen spectrofluorometry, which indicates the potential of clinical applicability in breast cancer diagnosis.

Objective To evaluate the effects of compound glycyrrhizin on the percentage of Th17 cells and expression of interleukin(IL)-17A in peripheral blood of patients with psoriasis vulgaris, and to explore their relationship with therapeutic effects. Methods A total of 30 patients with mild to moderate progressive psoriasis vulgaris were randomly and equally divided into two groups:group 1 treated with compound glycyrrhizin injection, antihistamines and topical drugs, group 2 treated with antihistamines and topical drugs. Twelve healthy human subjects served as the control group. Blood samples were collected from the patients 1 day before start of treatment and after 3 weeks of treatment, and from the control group. Flow cytometry and enzyme-linked immunosorbent assay (ELISA)were performed to determine the percentage of Th17 cells and expression level of IL-17A respectively in the peripheral blood samples. Results Before the treatment, the percentage of Th17 cells and expression level of IL-17A were both significantly higher in the two patient groups than in the control group (all P<0.05). After the treatment, group 1 showed significant decreases in the percentage of Th17 cells and expression level of IL-17A compared with those before the treatment (both P<0.05), while no significant differences were observed in group 2 between pre-and posttreatment IL-17A expression level or Th17 cell percentage (both P>0.05). Furthermore, both Th17 cell percentage and IL-17A expression were significantly different between the two patient groups after the treatment (both P< 0.05). Conclusion Compound glycyrrhizin may treat psoriasis vulgaris by regulating Th17 cell percentage and IL-17A expression in peripheral blood.

OBJECTIVE:To study the anti-inflammatory effect of Xinfeng capsule on adjuvant arthritis (AA) in rats. METH-ODS:70 SD rats were randomized into a normal control group(isovolumetric normal saline),a model control group(isovolumet-ric normal saline),a positive control TCM group [Qufeng zhitong capsule 0.4 g(crude drug)/kg],a positive control chemical medi-cine group(Leflunomide tablet 2.1 mg/kg)and groups of low,middle and high doses of Xinfeng capsule,which were respectively marked as groups A,B,C,D,E,F and G. All groups of rats except for Group A were given freund’s complete adjuvant intracu-taneous injection to establishe AA models,and from the 12th day after the inflammation was induced,were given the correspond-ing drug,ig,for 28 consecutive days. The degree of toe swelling and arthritis index were determined and calculated for all groups of rats before and after the administration. The contents of interleukin 1β(IL-1β) and tumor necrosis factor α(TNF-α) in serum and synovial membrane of all groups of rats were determined 24 h after the last administration,and pathomorphological changes of their ankles were observed by light microscope. RESULTS:Compared to group A,group B demonstrated higher degree of toe swelling,arthritis index and contents of IL-1β and TNF-α in serum and synovial membrane,with statistical significance(P<0.01). After the administration,the degree of toe swelling and arthritis index of groups C,D,E,F and G reduced,with statistical signifi-cance(P<0.05). Compared to group B,groups C,D,E,F and G showed lower degree of toe swelling,arthritis index and con-tents of IL-1β and TNF-α in serum and synovial membrane,with statistical significance(P<0.01 or P<0.05). Synovial membrane hyperplasia and inflammatory cell infiltration were noted in the ankle tissue of the rats in group B,and such symptoms were not so serious in groups C,D,F and G. CONCLUSIONS:Xinfeng capsule has anti-inflammatory effect for AA rats by a mechanism which may be related to accelerating synoviocyte apoptosis and inhibiting synovial membrane hyperplasia.
