China Journal of Chinese Materia Medica 2015;40(22):4510-4513
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 lowcost 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.

According to the designed specific primers of gene fragment based on the Salvia miltiorrhiza transcriptome data, a full-length cDNA sequence of SQS2 from S. miltiorrhiza f. alba was cloned by the method of reverse transcription polymerase chain reaction (RT-PCR). The SmSQS2 cDNA sequence was obtained, this sequence is named SmSQS2 and its GenBank registration number is KM244731. The full length of SmSQS2 cDNA was 1245 bp, encoding 414 amino acids including 5'UTR 115 bp and 3'UTR 237 bp. Sequence alignment and phylogenetic analysis demonstrated that SmSQS2 had relative close relationship to the SQS2 of S. miltiorrhiza. The induction of E. coli [pET28-SQS2] in different temperature, induction time, IPTG concentrations and density of inducing host bacterium (A600) were performed, Shaking the culture at 30 degrees C until the A600 is approximately 0.6 and add IPTG to final concentration of 0.2 mmol x L(-1), and then the optimal expression of SmSQS2 recombinant protein were accumulated after the induction time of 20 h. The research provided important base for the study of sterol and terpene biosynthesis of SQS2 in S. miltiorrhiza f. alba.

Objective To investigate the carrying rate and genotype of thalassemia in the household population of Yantian dis-trict in Shenzhen city so as to provide the scientific basis for Thalassemia genetic counseling,prenatal diagnosis and prevention plan. Methods 3 mL of anticoagulation blood by EDTA-K2 was extract for conducting the whole blood cells analysis.With the mean cor-puscular volume(MCV)<80 fL as the preliminary screening test,then the suspected cases were performed the DNA extraction for conducting the gene test.In theα-thalassemia detection,4 pairs of PCR primer were used to amplify in the same reaction system and the results were analyzed according to the band after the agarose gel electrophoresis.In theβ-thalassemia detection,the PCR product sequencing was adopted.Results After the preliminary screening,4 657 suspected cases all were performed the gene detection.510 carriers with thalassemia gene were detected out with the thalassemia gene carrying rate of 10.95%,including 389 cases carryingα-thalassemia gene with the carrying rate of 8.35%,which was dominated by α-3.7,α-4.2 and α-SEA,and 121 cases carrying βthalassemia gene with the carrying rate of 2.59%,which was dominated by CD41.42,LVS-Ⅱ-654,CD17 and CD71.Conclusion The carrying rate of thalassemia gene in the household population of Yantian district was 10.95%,which is closed to that in other districts within Guangdong province,all of the 8 detected genotypes of thalassemia are the common types.
