Wuyi is one of the Chinese medicine recorded in Shennong's Herbal Classic and many other herbal books during the long history period. Up to now, Wuyi is still an important medicine used for insecticidal and removing food retention. Recent researches indicated that Wuyi also had the function of anti-malaria and treating herpetic simplex keratitis. Therefore, Wuyi had notable value on clinic and development of new medicine. The herbalogical textual research on Wuyi was conducted through investigation of the literature of materia medica during the long historical period from Han Dynasty. It was demonstrated by this work that the original plants of Wuyi include Ulmus macrocarpa Hance and Hemiptelea davidii (Hance) Planch, in which, U. macrocarpa was the quality specie. U. pumila was the false specie which cause confusing. The medicine Wuyi was the processed product made from the nutlet of the plants through fermentation with other additive agents.

Objective To study the effects of propofol exposure during pregnancy on space cognitive and exploration abilities and expression of phosphorylated tau protein ( P-tau) and beta-amyloid protein[ Aβ(1-42) ] in hippocampus of the offspring. Methods Sprague-Dawley female (n=24) and male rats (n=8) of three months old were mated at the same cage at the ratio of 3:1. Pregnant rats were randomly divided into early group (group E), medium group (group M), late group (group L) and control group ( group C) , with 6 rats in each group. Groups E, M and L received propofol 80 mg · kg-1 · d-1 for 7 consecutive days. Propofol was replaced with equal volume of physiological saline in group C. Learning and memory of the 30-day offspring rats were assessed by using Morris water maze test. Then offspring rats were sacrificed to determine the expression of P-tau and Aβ(1-42) in the hippocampus by ELISA and immunohistochemistry. Results The learning and memory abilities were declined significantly in group E (51. 20±8. 11) s, group M (36. 00±6. 44) s and group L (47. 20±12. 30) s, as compared with group C (65. 60± 7. 23) s (all P<0. 05). The result of immunohistochemistry and ELISA showed that expression of Aβ(1-42) and P-tau in hippocampus was significantly higher in group M than in groups E, L and C[(immunohistochemistry: Aβ(1-42), (27. 38±5. 90) vs. (12. 65± 2. 08), (13. 79±3. 37), and (65. 60±7. 23); P-tau, (26. 35±5. 83) vs. (13. 65±3. 46), (14. 56±3. 82), and (8. 49±1. 20);ELISA:Aβ(1-42) , (88. 6±7. 43) vs. (71. 60±6. 79), (13. 79±3. 37), and (65. 80±6. 28);P-tau, (230. 13±8. 22) vs. (210. 42± 2.20), (210.95±1. 75), and (200. 65±1. 57)] (all P<0.05). Conclusion Multiple propofol injections may impair rat offspring’ s space cognitive abilities and exploration abilities, and the impairment is especially obvious in second trimester of pregnancy, which may be associated with over-expression of P-tau and Aβ(1-42) .

Orange peel was used as lowcost adsorbent in binding of Methylene Blue.The effects of equilibrium time,pH,dye concentration have been studied.Carboxyl,amine and phosphonate functional groups were present in the orange peel.The equilibrium time was 1 hour,the maximum adsorption capacities of the orange peel was 370.3?31.0 mg/g at pH 10.The Langmuir and Freundlich isotherms were well fitted in this biosorption system.Results showed relatively higher rate constant and biosorption capacities.These adsorption performance indicate the orange peel as a potentially economical adsorbent for dye removal.

OBJECTIVETo investigate the effect of Syk on the VEGF-C expression in breast cancer.

METHODSImmunohistochemical EnVision method was used to detect the protein expression of Syk, NFκB and VEGF-C in breast carcinoma; and the relationship between protein expression of Syk, NFκB, VEGF-C and lymph node metastasis was analysed. MDA-MB-231 cells were transfected with pcDNA3.1(-)-Syk, and the effect of Syk gene on the VEGF-C and NFκB expression was determined.

RESULTSIn the lymph node metastatic group, a lower expression rate of Syk and higher expression rate of VEGF-C and NFκB were detected as compared to the non-metastatic group. The expression of Syk was negatively associated with NFκB (r = -0.448, P = 0.002) and VEGF-C (r = -0.620, P = 0.000) expression, and VEGF-C was associated with the nuclear expression of NFκB (r = 0.310, P = 0.036). Compared with the non-transfected cells, the pcDNA3.1(-)-Syk transfected MDA-MB-231 cells showed significantly lower transcriptional level of VEGF-C mRNA, expression level of VEGF-C protein and NFκB activity (P < 0.05).

CONCLUSIONSSyk may play an important role in the lymph node metastasis of breast cancer. It may down-regulate the expression of VEGF-C by inhibiting the activity of NFκB, which thus suppresses lymph node metastasis of breast cancer.

OBJECTIVETo explore the surgical method and its clinical effects of minimally invasive osteosynthesis on the treatment of complex ankle fractures.

METHODSFrom January 2007 to December 2011, 53 patients with complex ankle fractures were treated with minimally invasive osteosynthesis. There were 31 males and 22 females, with an average age of 38.2 years old (ranged, 18 to 65). According to the system of Lauge-Hansen, 32 fractures were supination external rotation injury (grade WV), 13 fractures were pronation external rotation (grade III or IV), 5 fractures were pronation abduction (grade III); and 3 fractures can not be classified due to serious comminution fracture of fibula. According to the system of Denis-Weber, there were 4 cases with type A, 34 cases with type B and 15 cases with type C. Seven cases were open fractures. The duration from injuries to operation ranged from 2 hours to 14 days with an average of 5 days. The sequence of reduction and fixation of ankle fractures was firstly posterior malleolus, then medial malleolus and lateral malleolus, and inferior tibiofibular syndesmosis lastly. The fractures of posterior malleolus were reduced and fixed through anterior ankle approaches; the fractures of medial and lateral malleolus were percutaneously fixed with bolts or blade plate or tensile force band; and inferior tibiofibular syndesmosis were firmly fixed if necessary. Baird-Jackson scoring system was used to evaluate clinical effects.

RESULTSForty-eight patients were followed up from 10 to 36 months with an average of 13 months. The fractures got healing with an average time of 12 weeks (ranged, 10 to 18). According to the Baird-Jackson scoring system, the mean score of ankle function was 94.7 +/- 4.2, and 28 cases obtained excellent results, 15 good, 3 fair and 2 poor. One case experienced superficial infections and was cured by changing dressings, 2 cases experienced fixed syndesmosis screw breakage.

CONCLUSIONThe surgical method of minimally invasive osteosynthesis can ensure the anatomical join restoration, protect the blood supply of fracture end, rebuild the function of ankle joint, obtain satisfactory clinical results in treating complex ankle fractures.
