Objective To observe the efficacy of WS-frequency spectrum in treating second degree burn wounds. Methods 350 cases of second degree burn were treated in the whole couse with WS-frequency spectrum in association with systemic treatment including anti-shock,anti-infection and expecant treatment. Results All the patiens healed,only 23 cases with deep burn area over 20% TBSA resulted in superficial pigmentation and scar formation without dysfuntion. Conclusion WS-frequency spectrum is a good remedy for treating second degree burn. This method is easy and simple to apply and has very good efficacy.

The role of flavonoids of Echinps latifolius (FELT) in Wnt signaling was investigated in adjuvant arthritis (AA) rats. The therapeutic effects of FELT on AA rats were detected by rat arthritis score and MTT. The effect of FELT gavage treatment on the Wnt signaling key gene β-catenin, C-myc and cyclin D1 in synovium from AA rats was detected by Real-time qPCR, and the effects of FELT gavage treatment on the upstream negative regulation gene SFRP 1,2,4,5 in synovium from AA rats were detected by Real-time qPCR. The results showed that FELT gavage treatment significantly inhibited arthritis score and MTT values in AA rats, significantly inhibited the expression of the Wnt signaling gene β-catenin, C-myc and cyclin D1, significantly up-regulated the expression of the up- stream negative regulation gene SFRP 1,2,4. FELT has a better therapeutic effect for AA rats.

Objective To study the imaging characteristics of the ligaments in craniocervical junction (CCJ), and to optimize the examination methods and scanning sequences of the ligaments in this region. Methods Two groups of 51 healthy volunteers in each were selected to undergo CT and MRI examination respectively. The CT and MRI features of the ligaments in CCJ were assessed. Two senior imaging doctors compared the results of showing the ligaments in CCJ by several MRI sequences, including T1 WI ,T2 WI, proton density weighted imaging (PDWI), T2 * WI and short time inversion recovery (STIR) ,and proton density fat saturate (PDFSAT). Standard normal rank transformation was done according to the primary data,and then analysis of variance of repeated measurement was applied. Results CT and MRI could both demonstrate the ligaments (except the anterior atlantooccipital membrane only seen on MRI) and their adjoins in CCJ, while MRI had more advantages than CT. The display ratio of the anterior atlantooccipital membrane was 100% (51/51) by MRI. The display ratio of the apical ligament was 29.4%(15/51) by CT and 43.1% (22/51) by MRI. The posterior atlantooccipital membrane-dura complex,tectorial ligament-dura complex, transverse ligament, and alar ligament could be demonstrated clearly by CT and MRI, the display ratio was 100% respectively (51/51). The results of PDWi scored by two doctors were both 5.0, there were no significant differences between them (F = 0.000, P > 0.05), which were significantly higher than T, WI (M = 3.0), T2Wi (M = 3.0), T2 * WI (M = 1.0), STIR (M = 1.0), and PDFSAT(M = 3.0)(P < 0.01). Conclusion MRI was superior to CT in demonstrating the ligaments in CCJ. PDWI was the optimal MRI sequence. Imaging research of normal ligamentous structures in CCJ could provide valuable diagnostic and therapeutic information for evaluating the ligamentous diseases.

The levels and abnormal rates of platelet, serum sodium and serum creatinine were compared. Results The T3 - T5 serum creatinine levels in deterioration died group were significantly higher than those in improvement survival group: (102.14 ± 75.67) μmol/L vs. (78.21 ± 26.68) μmol/L, (116.45 ± 110.64)μmol/L vs. (78.77 ± 29.25) μmol/L, (161.43 ± 153.23) μmol/L vs. (76.40 ± 27.26) μmol/L, and the T1 - T5 serum sodium and platelet levels were significantly lower than those in improvement survival group:(135.05 ± 6.24) mmol/L vs. (137.52 ± 5.26) mmol/L, (137.01 ± 4.99) mmol/L vs. (139.00 ± 3.89) mmol/L, (134.80 ± 16.74) mmol/L vs. (139.15 ± 3.77) mmol/L, (134.40 ± 11.69) mmol/L vs. (138.30 ± 8.75) mmol/L, (133.30 ± 8.93) mmol/L vs. (139.01 ± 9.10) mmol/L, and (122.46 ± 72.59) × 109/L vs. (149.70 ± 71.70) ×109/L, (110.18 ± 65.10) × 109/L vs. (152.09 ± 82.79) ×109/L, (107.32 ± 70.49) ×109/L vs. (169.32 ± 100.65) ×109/L, (97.06 ± 58.15) ×109/L vs. (183.57 ± 112.68) ×109/L, (94.66 ± 57.00) × 109/L vs. (191.36 ± 118.64) ×109/L, and there were statistical differences (P<0.05). The abnormal rates of T3-T5 serum creatinine, T2 - T5 serum sodium and T1 - T5 platelet in deterioration died group were significantly higher than those in improvement survival group, the serum creatinine: 22.06%(15/68) vs. 6.90% (6/87), 27.49% (19/68) vs. 8.05% (7/87) and 42.65% (29/68) vs. 10.34% (9/87), the serum sodium: 32.35% (22/68) vs. 13.79% (12/87), 39.71% (27/68) vs. 14.94% (13/87), 48.53% (33/68) vs. 12.64%(11/87) and 60.29%(41/68) vs. 11.49%(10/87), the platelet:45.59%(31/68) vs. 21.84%(19/87), 55.88% (38/68) vs. 24.14% (21/87), 54.41% (37/68) vs. 25.29% (22/87), 55.88% (38/68) vs. 21.84%(19/87) and 61.76% (42/68) vs. 20.69% (18/87), and there were statistical differences (P<0.05). Abnormal rate of platelet was highest in each time point. Conclusions In the course of pathological changes in deterioration and dead patients, the platelet is the first and most easily affected compare with serum sodium and serum creatinine; the platelet may be a sensitive marker for predicting clinical outcome in patients with liver failure.

Objective To learn the plague's host animals and parasitic flea composition, and to investigate the natural foci of plague in Xiji county in order to provide basic information for plague prevention and control. Methods The Citellus alaschanicus density, nocturnal rodents, the body flea, the burrow track flea, the nest flea were investigated in 8 townships (town) of Xiji county from June 11 2007 to July 25 2007. Specimens of small mammalian, fleas were collected for bacteriological and serological testing. Results The average density of the main host Citellus alaschanicus was 0.85 per hectare. The nocturnal mouse capture rate was 0.80%(24/2987).The survey found 16 species of small mammals that belonging to 3 orders, 9 families and 16 species with Citellus alaschanicus the dominant species. The Citellus alaschanicus had 2.84 fleas per body. Four families and 16 species of fleas were identified in the areas. The Citellus alaschanicus and Citellophilus Tesquorum Mongolicus were the dominant species. Plague bacteriology and serology tests were negative. Conclusions The study shows that the area is suitable for the formation of natural foci of Citellus alaschanicus plague. Surveillance is an important measure for prevention and control of the plague.

To study the effect of pulchinenoside (PULC) on the Frizzled (FZD) expression of adjuvant arthritis ( AA) rats. AA rats were prepared through the toe injection with complete Freund's adjuvant to culture fibroblast-like synoviocytes (FLS). The effect of the oral administration with PULC on the FZD8 expression was detected by the real time qPCR. The effect of FZD8 knockout on the expressions of IL-1, IL-6, IL-8 were detected by MTT and ELISA. The role of miR-375 in the abnomal expression of FZD8 was detected by the real time qPCR. The results showed signfiicant decrease in the FZD8 expression among AA rats, FLS proliferation ater FZD8 knockout and IL-1, IL-6, IL-8 expressions and notable increase in miR-375 expression after the oral administration with PULC. The up-regulated miR-375 expression can inhibit the FZD8 expression. PULC may inhibit the FZD8 expression by up-regulating the miR-375 expression.

The role of pulchinenoside (PULC) in the regulation of MeCP2 expression was investigated in RA model rats. Adjuvant arthritis rats were used as RA model rats, and fibroblast-like synoviocytes (FLS) from the RA model rats were cultured. The effect of 100 mg x kg(-1) PULC gavage treatment on the MeCP2 expression and the effect of MeCP2 siRNA on the expression of SFRP2 and β-catenin were detected by real time qPCR and Western blotting. The role of PULC in the FLS proliferation was detected by MTT. The results showed that the MeCP2 expression was down-regulated, the SFRP2 expression was up-regulated and the FLS proliferation was inhibited in FLS after therapy. MeCP2 siRNA significantly inhibited the MeCP2 expression, up-regulated the SFRP2 expression and inhibited the β-catenin expression in FLS from RA model rats. PULC may increase the SFRP2 expression, inhibit the Wnt signaling and inhibit the FLS proliferation in FLS from the RA model rats by inhibiting the MeCP2 expression.
